Description

生体情報測定装置および血圧計Biometric information measuring device and sphygmomanometer
　この発明は生体情報測定装置に関し、より詳しくは、マイクロフォンを備えた外部端末と音波（超音波を含む。）を介して通信を行う生体情報測定装置に関する。また、この発明は、そのような生体情報測定装置を備えた血圧計に関する。 The present invention relates to a biological information measuring device, and more particularly to a biological information measuring device that communicates with an external terminal equipped with a microphone via sound waves (including ultrasonic waves). The present invention also relates to a sphygmomanometer provided with such a biometric information measuring device.
　従来、外部へ音波を発する生体情報測定装置として、例えば特許文献１（特開２００７－３０９７８６号公報）に開示されている電子体温計のように、振動板を含むブザーを備え、内ケースと、この内ケースに対向するブザーカバーとの間に、前記ブザーの振動板を挟み込むように固定したものが知られている。前記ブザーカバーは、外ケース（表示器が設けられた側）の内壁面によって、前記ブザーへ向けて押圧されている。 Conventionally, as a biological information measuring device that emits sound waves to the outside, for example, like the electronic thermometer disclosed in Patent Document 1 (Japanese Unexamined Patent Publication No. 2007-309786), a buzzer including a diaphragm is provided, and an inner case and the buzzer are provided. It is known that the diaphragm of the buzzer is fixed so as to be sandwiched between the buzzer cover and the buzzer cover facing the inner case. The buzzer cover is pressed toward the buzzer by the inner wall surface of the outer case (the side on which the display is provided).
特開２００７－３０９７８６号公報JP-A-2007-309786
　ところで、最近、本出願人は、生体情報として血圧を測定する卓上式血圧計であって、ハウジング内にブザー（振動部材）を収容し、ブザーの振動によってハウジングの壁面を振動させて音波を発し、マイクロフォンを備えた外部端末と音波を介して通信を行うものを開発している。 By the way, recently, the applicant is a desktop sphygmomanometer that measures blood pressure as biological information. A buzzer (vibration member) is housed in the housing, and the wall surface of the housing is vibrated by the vibration of the buzzer to emit sound waves. , We are developing a device that communicates with an external terminal equipped with a microphone via sound waves.
　ここで、普及型の卓上式血圧計では、ハウジング（血圧計本体をなす筐体）は、略平板状の底壁部とその周縁から上方へ延びる側壁部とを一体に含む下ハウジングと、略平板状の上ハウジングとを組み合わせて構成されることがある。上ハウジングには、表示器および操作スイッチが配置されるため、仮に上ハウジングの内面にブザーを固定して、上ハウジングを振動させる構成を採用すると、振動の伝達状態（つまり、通信状態）が悪くなる可能性がある。特に、上ハウジングの上面がフロント銘板で覆われるデザインを採用する場合は、さらに通信状態が悪化する可能性がある。また、下ハウジングの底壁部は、テーブル等に面するため、音波通信に用いるには不向きである。また、側壁部（縦壁）にブザーを固定しようとする場合、単に上ハウジングと下ハウジングとの間にブザーを挟み込むような固定構造（従来例並みの固定構造）を採用することができず、固定のための新たな工夫を要する。 Here, in the popular desktop sphygmomanometer, the housing (housing forming the main body of the sphygmomanometer) is a lower housing including a substantially flat bottom wall portion and a side wall portion extending upward from the peripheral edge thereof, and abbreviated. It may be configured in combination with a flat upper housing. Since the display and operation switch are arranged in the upper housing, if a buzzer is fixed to the inner surface of the upper housing and the upper housing is vibrated, the vibration transmission state (that is, the communication state) is poor. There is a possibility of becoming. In particular, when the design in which the upper surface of the upper housing is covered with the front name plate is adopted, the communication condition may be further deteriorated. Further, since the bottom wall portion of the lower housing faces a table or the like, it is not suitable for use in sound wave communication. Further, when trying to fix the buzzer to the side wall (vertical wall), it is not possible to adopt a fixing structure (fixing structure similar to the conventional example) in which the buzzer is simply sandwiched between the upper housing and the lower housing. A new device for fixing is required.
　そこで、この発明の課題は、マイクロフォンを備えた外部端末と音波を介して通信を行う生体情報測定装置であって、ハウジングをなす側壁部の内面に振動部材を固定して側壁部を振動させることにより、音波による通信状態を良好に保つことができる生体情報測定装置を提供することにある。また、この発明の課題は、そのような生体情報測定装置を備えた血圧計を提供することにある。 Therefore, an object of the present invention is a biological information measuring device that communicates with an external terminal provided with a microphone via sound waves, in which a vibrating member is fixed to the inner surface of a side wall portion forming a housing to vibrate the side wall portion. Therefore, it is an object of the present invention to provide a biological information measuring device capable of maintaining a good communication state by sound waves. Another object of the present invention is to provide a sphygmomanometer provided with such a biometric information measuring device.
　上記課題を解決するため、この開示の生体情報測定装置は、
　マイクロフォンを備えた外部端末と音波を介して通信を行う生体情報測定装置であって、
　内部に収容空間を有するハウジングと、
　上記収容空間の内部に配置され、受けた信号に基づいて振動する振動部材と、
　上記ハウジングとは別体として構成され、上記振動部材を保持した状態で上記ハウジングに固定された保持部材と
を備え、
　上記ハウジングは、
　面状に延在する第１壁部と、
　上記第１壁部に対向しかつ面状に延在する第２壁部と、
　上記第１壁部および上記第２壁部に交差して延在する側壁部と

　上記側壁部の内面に、上記保持部材が、上記振動部材の振動を上記側壁部に伝達させる態様で固定されている、ことを特徴とする。 In order to solve the above problems, the biometric information measuring device of this disclosure is
A biometric information measuring device that communicates with an external terminal equipped with a microphone via sound waves.
A housing with an internal storage space and
A vibrating member that is placed inside the accommodation space and vibrates based on the received signal,
It is configured as a separate body from the housing, and includes a holding member fixed to the housing while holding the vibrating member.
The above housing
The first wall that extends in a plane and
The second wall portion facing the first wall portion and extending in a plane shape,
The accommodation space is defined by the first wall portion and the side wall portion extending across the second wall portion.
The holding member is fixed to the inner surface of the side wall portion in such a manner that the vibration of the vibrating member is transmitted to the side wall portion.
　本明細書で、「音波」とは、空中を伝播する弾性波を指し、人間の可聴周波数（２０Ｈｚ～２０ｋＨｚ程度）より高い周波数をもつ超音波を含む。 In the present specification, "sound wave" refers to an elastic wave propagating in the air, and includes ultrasonic waves having a frequency higher than the human audible frequency (about 20 Hz to 20 kHz).
　典型的には、ハウジングの「第１壁部」は上壁、「第２壁部」は底壁を指すが、これに限られるものではない。 Typically, the "first wall" of the housing refers to the upper wall and the "second wall" refers to the bottom wall, but it is not limited to this.
　上記側壁部の「内面」とは、上記側壁部の両面のうち、上記ハウジングの内部（収容空間）の側の面を指す。 The "inner surface" of the side wall portion refers to the surface of both sides of the side wall portion on the side of the inside (accommodation space) of the housing.
　この開示の生体情報測定装置では、上記ハウジングは、面状に延在する第１壁部と、上記第１壁部に対向しかつ面状に延在する第２壁部と、上記第１壁部および上記第２壁部に交差して延在する側壁部とによって上記収容空間を画定している。そして、上記側壁部の内面に、上記振動部材を保持した状態の上記保持部材が、上記振動部材の振動を上記側壁部に伝達させる態様で固定されている。したがって、上記振動部材が信号を受けて振動すると、上記側壁部が振動して、上記ハウジングの外部へ音波が発せられる。これにより、マイクロフォンを備えた外部端末と音波を介して通信が行われる。 In the biological information measuring device of the present disclosure, the housing has a first wall portion extending in a planar shape, a second wall portion facing the first wall portion and extending in a planar shape, and the first wall portion. The accommodation space is defined by a portion and a side wall portion extending so as to intersect the second wall portion. Then, the holding member in a state of holding the vibrating member is fixed to the inner surface of the side wall portion in such a manner that the vibration of the vibrating member is transmitted to the side wall portion. Therefore, when the vibrating member receives a signal and vibrates, the side wall portion vibrates and a sound wave is emitted to the outside of the housing. As a result, communication is performed with an external terminal equipped with a microphone via sound waves.
　典型的な使用態様として、上記ハウジングが卓上に置かれる場合、例えば、表示器、操作スイッチなどが配置された第１壁部が上壁としてユーザに面する一方、第２壁部は底壁としてテーブル等に面することが想定される。側壁部では、通常、配置されるべき部品が比較的少ないので、比較的広い領域（面積）が振動（したがって、音波通信）のために確保され得る。そのような状況下で、この生体情報測定装置によれば、上記側壁部の比較的広い領域（面積）を振動させて、外部へ音波を発することができる。したがって、音波による通信状態を良好に保つことができる。 As a typical usage mode, when the housing is placed on a table, for example, the first wall portion on which an indicator, an operation switch, etc. are arranged faces the user as an upper wall, while the second wall portion serves as a bottom wall. It is expected to face a table or the like. Since there are usually relatively few components to be placed on the sidewalls, a relatively large area (area) can be reserved for vibration (and therefore sonic communication). Under such circumstances, according to this biological information measuring device, it is possible to vibrate a relatively wide area (area) of the side wall portion and emit sound waves to the outside. Therefore, it is possible to maintain a good communication state by sound waves.

It is characterized by that.
　本明細書で、「圧電ブザー」とは、上記圧電素子層に上記信号としての電気信号を受けて、上記圧電素子層が振動を生ずるタイプの公知の部材である。 In the present specification, the "piezoelectric buzzer" is a known member of a type in which the piezoelectric element layer receives an electric signal as the signal and the piezoelectric element layer vibrates.
　金属板の「第一の面」、「第二の面」とは、面状に延在する二つの板面を指す（つまり、端面ではない。）。同様に、板部の「一方の板面」、「他方の板面」も、面状に延在する二つの板面を指す（つまり、端面ではない。）。 The "first surface" and "second surface" of a metal plate refer to two plate surfaces extending in a plane shape (that is, they are not end faces). Similarly, the "one plate surface" and the "other plate surface" of the plate portion also refer to two plate surfaces extending in a plane shape (that is, they are not end faces).
　この一実施形態の生体情報測定装置では、上記振動部材は、面状に延在する金属板と、この金属板の第一の面に固定された圧電素子層とを有する圧電ブザーであり、実質的に板状の外形を有する。上記保持部材をなす上記板部の一方の板面は、上記圧電ブザーの上記金属板の第二の面（圧電素子層が固定された第一の面とは反対側の面）に接触している。また、上記保持部材をなす上記挟持部（上記板部の端部に設けられている）は、上記金属板の端部の少なくとも２箇所を上記板部と共に挟持している。これにより、上記保持部材が、実質的に板状の外形を有する上記圧電ブザーを保持した状態になっている。そして、上記板部の上記一方の板面とは反対側の他方の板面が上記側壁部の内面に接触することによって、上記圧電ブザーの振動が、上記板部を介して上記ハウジングの上記側壁部に伝達される。したがって、この一実施形態の生体情報測定装置では、上記振動部材が実質的に板状の外形を有する上記圧電ブザーである場合に、音波による通信状態を良好に保つことができる。 In the biological information measuring device of this embodiment, the vibrating member is a piezoelectric buzzer having a metal plate extending in a plane shape and a piezoelectric element layer fixed to the first surface of the metal plate, which is substantially the same. It has a plate-like outer shape. One plate surface of the plate portion forming the holding member is in contact with the second surface of the metal plate of the piezoelectric buzzer (the surface opposite to the first surface on which the piezoelectric element layer is fixed). There is. Further, the holding portion (provided at the end portion of the plate portion) forming the holding member holds at least two positions of the end portion of the metal plate together with the plate portion. As a result, the holding member is in a state of holding the piezoelectric buzzer having a substantially plate-like outer shape. Then, when the other plate surface of the plate portion opposite to the one plate surface comes into contact with the inner surface of the side wall portion, the vibration of the piezoelectric buzzer is transmitted through the plate portion to the side wall of the housing. It is transmitted to the department. Therefore, in the biological information measuring device of this embodiment, when the vibrating member is the piezoelectric buzzer having a substantially plate-like outer shape, the communication state by sound waves can be kept good.
　また、実質的に板状の外形を有する上記圧電ブザーの上記圧電素子層が設けられている側では、大部分の領域（上記金属板の端部以外の領域）が、上記保持部材に覆われることなく、開放され得る。その場合、上記保持部材によって干渉されることなく、例えば上記収容空間の内部に配置された制御部から配線を介して、上記圧電素子層に対して上記信号としての電気信号を供給することができる。 Further, on the side of the piezoelectric buzzer having a substantially plate-like outer shape on which the piezoelectric element layer is provided, most of the region (the region other than the end of the metal plate) is covered with the holding member. Can be released without. In that case, an electric signal as the signal can be supplied to the piezoelectric element layer from, for example, a control unit arranged inside the accommodation space via wiring without being interfered by the holding member. ..

The inner surface of the side wall has a specific shape that is inclined or curved from the first wall to the second wall.
The other plate surface of the plate portion has a shape along the inner surface of the side wall portion.

　例えば、上記第２壁部と上記側壁部とが一体成形される場合、金型から成形品を取出し易くするために、金型のキャビティやコアに抜き勾配がつけられることがある。それに応じて、上記側壁部の内面は、上記第１壁部から上記第２壁部へ向かって傾斜または湾曲した形状を有することになる。ここで、仮に上記板部の上記他方の板面が単なる平坦面であったとすると、上記板部の上記他方の板面と上記側壁部の内面との間に隙間が生じて、上記圧電ブザーの振動が、上記ハウジングの上記側壁部へ伝わり難くなる。そこで、この一実施形態の生体情報測定装置では、上記側壁部の内面が上記第１壁部から上記第２壁部へ向かって傾斜または湾曲した特定の形状を有する場合に、上記板部の上記他方の板面が、上記側壁部の内面に沿った形状を有するものとしている。これにより、上記板部の上記他方の板面と上記側壁部の内面とが密接して、上記圧電ブザーの振動が、上記ハウジングの上記側壁部へ伝わり易くなる。この結果、音波による通信状態を良好に保つことができる。 For example, when the second wall portion and the side wall portion are integrally molded, a draft may be provided in the cavity or core of the mold in order to facilitate the removal of the molded product from the mold. Accordingly, the inner surface of the side wall portion will have a shape that is inclined or curved from the first wall portion to the second wall portion. Here, assuming that the other plate surface of the plate portion is merely a flat surface, a gap is generated between the other plate surface of the plate portion and the inner surface of the side wall portion, and the piezoelectric buzzer is used. Vibration is less likely to be transmitted to the side wall portion of the housing. Therefore, in the biometric information measuring device of this embodiment, when the inner surface of the side wall portion has a specific shape inclined or curved from the first wall portion to the second wall portion, the plate portion is described above. The other plate surface is assumed to have a shape along the inner surface of the side wall portion. As a result, the other plate surface of the plate portion and the inner surface of the side wall portion are brought into close contact with each other, and the vibration of the piezoelectric buzzer is easily transmitted to the side wall portion of the housing. As a result, the communication state by sound waves can be kept good.

The plate portion has an opening that penetrates from one plate surface to the other plate surface in the plate thickness direction.
The second surface of the metal plate comes into contact with the inner surface of the side wall portion through the opening, and the vibration of the piezoelectric buzzer is directly transmitted to the side wall portion.
It is characterized by that.
　この一実施形態の生体情報測定装置では、上記金属板の上記第二の面が、上記板部の上記開口部を介して上記側壁部の内面に接触し、上記圧電ブザーの振動が上記側壁部に直接的に伝達される。したがって、振動の伝達効率が高まって、音波による通信状態を良好に保つことができる。 In the biometric information measuring device of this embodiment, the second surface of the metal plate comes into contact with the inner surface of the side wall portion through the opening of the plate portion, and the vibration of the piezoelectric buzzer causes the side wall portion. Is directly transmitted to. Therefore, the transmission efficiency of vibration is increased, and the communication state by sound waves can be kept good.

A part of the inner surface of the side wall protrudes toward the second surface of the metal plate so that the second surface of the metal plate contacts the inner surface of the side wall through the opening. Has a shape,

　この一実施形態の生体情報測定装置では、上記金属板の上記第二の面が上記開口部を介して上記側壁部の内面に接触するように、上記金属板の上記第二の面に向けて上記側壁部の内面の一部が突出した形状を有している。したがって、上記板部が板厚（上記一方の板面と上記他方の板面との間の寸法）を有していても、上記金属板の上記第二の面が、上記板部の上記開口部を介して上記側壁部の内面に確実に接触する。 In the biological information measuring device of this embodiment, the second surface of the metal plate is directed toward the second surface of the metal plate so as to come into contact with the inner surface of the side wall portion through the opening. A part of the inner surface of the side wall portion has a protruding shape. Therefore, even if the plate portion has a plate thickness (dimension between the one plate surface and the other plate surface), the second surface of the metal plate is the opening of the plate portion. It surely contacts the inner surface of the side wall portion through the portion.

The holding member, which is composed of a component integrated with the side wall portion and holds the piezoelectric buzzer in the region corresponding to the holding member inside the side wall portion, is formed from one direction along the inner surface of the side wall portion. A holding member installation unit that can be slid and inserted is provided.
The holding member has an elastic portion exhibiting elasticity that protrudes from the plate portion or the sandwiching portion in a direction intersecting the one direction.
In a state where the holding member is slid and inserted from the one direction with the deformation of the elastic portion, the elastic portion of the holding member is formed from the component forming the holding member installation portion. The plate portion is urged toward the inner surface of the side wall portion by receiving a pressing force toward the inner surface of the side wall portion.

　本明細書で、保持部材設置部が「側壁部と一体の構成要素からな」るとは、保持部材設置部の構成要素が上記側壁部と直接連なっている場合に限られず、例えば、保持部材設置部の構成要素が第２壁部に連なり、上記第２壁部を介して上記側壁部と一体になっていてもよい、ことを意味する。 In the present specification, the term "the holding member installation portion is composed of a component integrated with the side wall portion" is not limited to the case where the component of the holding member installation portion is directly connected to the side wall portion, for example, the holding member. It means that the components of the installation portion may be connected to the second wall portion and may be integrated with the side wall portion via the second wall portion.
　また、「側壁部の内面に沿った一方向」とは、例えば、上記第１壁部から上記第２壁部へ向かう方向を指す。ただし、その方向に限られるものではなく、例えば、上記第１壁部または上記第２壁部と平行な方向などであってもよい。 Further, "one direction along the inner surface of the side wall portion" refers to, for example, the direction from the first wall portion to the second wall portion. However, the direction is not limited to that, and may be, for example, a direction parallel to the first wall portion or the second wall portion.
　この一実施形態の生体情報測定装置では、上記側壁部の内側の上記保持部材に対応する領域に、上記側壁部と一体の構成要素からなり、上記圧電ブザーを保持した状態の上記保持部材が、上記側壁部の内面に沿った一方向からスライドして挿入され得る保持部材設置部が設けられている。上記保持部材は、上記板部または上記挟持部から上記一方向と交差する向きに突出した弾性部を有する。これにより、上記保持部材設置部に上記保持部材が上記弾性部の変形を伴って上記一方向からスライドして挿入された状態で、上記保持部材設置部をなす上記構成要素から上記保持部材の上記弾性部が上記側壁部の内面へ向けて押圧力を受けて、上記板部が上記側壁部の内面へ向けて付勢され、押し付けられる。したがって、仮に上記保持部材設置部から上記保持部材が離脱する向きの力が加わったとしても、上記板部と上記側壁部の内面との間に摩擦力が生じて、上記保持部材設置部から上記保持部材が離脱するのは抑制される。つまり、上記保持部材設置部に上記保持部材が上記弾性部の変形を伴って上記一方向からスライドして挿入されれば、上記保持部材設置部に上記保持部材が固定された状態となる。また、上記板部が上記側壁部の内面へ向けて付勢され、押し付けられるので、上記圧電ブザーから上記側壁部の内面への振動の伝達効率が高まって、音波による通信状態をさらに良好に保つことができる。 In the biometric information measuring device of this embodiment, the holding member in a state of holding the piezoelectric buzzer, which is composed of a component integrated with the side wall portion, is formed in a region corresponding to the holding member inside the side wall portion. A holding member installation portion that can be inserted by sliding from one direction along the inner surface of the side wall portion is provided. The holding member has an elastic portion protruding from the plate portion or the holding portion in a direction intersecting the one direction. As a result, in a state where the holding member is slid and inserted from the one direction with the deformation of the elastic portion, the holding member is inserted into the holding member installation portion from the constituent elements forming the holding member installation portion. The elastic portion receives a pressing force toward the inner surface of the side wall portion, and the plate portion is urged and pressed toward the inner surface of the side wall portion. Therefore, even if a force is applied in the direction in which the holding member is separated from the holding member installation portion, a frictional force is generated between the plate portion and the inner surface of the side wall portion, and the holding member installation portion is described as described above. The holding member is prevented from coming off. That is, when the holding member is slid and inserted from the one direction with the deformation of the elastic portion, the holding member is fixed to the holding member installation portion. Further, since the plate portion is urged and pressed toward the inner surface of the side wall portion, the transmission efficiency of vibration from the piezoelectric buzzer to the inner surface of the side wall portion is increased, and the communication state by sound waves is further maintained. be able to.

ことを特徴とする。 In the biological information measuring device of one embodiment,
The first wall portion is configured to be removable in one direction with respect to the side wall portion.
In the region corresponding to the holding member inside the side wall portion, a holding member installation portion which is composed of a component integrated with the side wall portion and can receive the holding member in a state of holding the piezoelectric buzzer is provided.
The holding member has an elastic portion exhibiting elasticity that protrudes from the plate portion or the sandwiching portion in a direction intersecting the one direction.
In a state where the first wall portion is mounted on the side wall portion, a holding rib extending toward the holding member installation portion is provided integrally with the first wall portion.
The holding member in a state where the piezoelectric buzzer is held is received by the holding member installation portion, and the holding member is attached to the holding member from the holding rib in a state where the first wall portion is attached to the side wall portion. The elastic portion receives a pressing force toward the inner surface of the side wall portion, and the plate portion is urged toward the inner surface of the side wall portion.
It is characterized by that.
　本明細書で、上記第１壁部は、上記側壁部に対して「一方向に着脱可能」とは、典型的には、上記側壁部に対して、上記第２壁部へ向って装着され得、また、その逆に、上記側壁部に対して、上記第２壁部から遠ざかる向きに取り外され得ることを指す。 In the present specification, the said that the first wall portion is "removable in one direction" with respect to the side wall portion is typically mounted on the side wall portion toward the second wall portion. On the contrary, it means that the side wall portion can be removed in a direction away from the second wall portion.
　この一実施形態の生体情報測定装置では、上記保持部材は、上記板部または上記挟持部から上記一方向と交差する向きに突出した、弾性を示す弾性部を有する。また、上記第１壁部と一体に、この第１壁部が上記側壁部に対して装着された状態で、上記保持部材設置部へ向けて延在する押さえリブが設けられている。上記保持部材設置部に上記圧電ブザーを保持した状態の上記保持部材が受けられ、かつ、上記第１壁部が上記側壁部に対して装着された状態で、上記押さえリブから上記保持部材の上記弾性部が上記側壁部の内面へ向けて押圧力を受けて、上記板部が上記側壁部の内面へ向けて付勢され、押し付けられる。したがって、上記圧電ブザーから上記側壁部の内面への振動の伝達効率が高まって、音波による通信状態をさらに良好に保つことができる。 In the biometric information measuring device of this embodiment, the holding member has an elastic portion exhibiting elasticity that protrudes from the plate portion or the sandwiching portion in a direction intersecting the one direction.

The elastic portion receives a pressing force toward the inner surface of the side wall portion, and the plate portion is urged and pressed toward the inner surface of the side wall portion. Therefore, the efficiency of transmitting vibration from the piezoelectric buzzer to the inner surface of the side wall portion is increased, and the communication state by sound waves can be maintained even better.

A sphygmomanometer that measures blood pressure by pressing the area to be measured.
Equipped with the above biometric information measuring device
The above housing
As the side wall portion, there is a first side wall portion that defines one of the four directions of the accommodation space, and a second side wall portion that defines another direction different from the one of the four directions.
A pump for supplying a fluid for compressing the measurement site is provided inside the accommodation space.
An air tube connection port for supplying the fluid from the pump to the outside of the housing is provided on the first side wall portion.
The holding member is fixed to the inner surface of the second side wall portion.
　本明細書で、典型的には、上記収容空間の「四方位」とは、前後左右の方位を指す。 In the present specification, the "four directions" of the accommodation space typically refer to the front-back, left-right directions.
　この開示の血圧計では、上記生体情報測定装置を備えているので、マイクロフォンを備えた外部端末と音波を介して通信を行うことができる。また、この血圧計では、上記収容空間の内部に、被測定部位を圧迫するための流体を供給するポンプを有し、上記ポンプからの流体をハウジング外部へ供給するためのエアチューブ接続口が、上記収容空間の四方位のうち一方位を画定する第１側壁部に設けられている。このため、仮に上記第１側壁部の内面に上記保持部材を固定して、上記保持部材に保持された状態の上記振動部材（または圧電ブザー）によって上記第１側壁部を振動させる構成にすると、振動の伝達状態（つまり、通信状態）が悪くなる可能性がある。そこで、この血圧計では、上記保持部材が、上記収容空間の四方位のうち上記一方位とは異なる他の方位を画定する上記第２側壁部の内面に固定されている。上記第２側壁部では、上記エアチューブ接続口その他の血圧計の構成部品を配置しないことによって、比較的広い領域（面積）が振動（したがって、音波通信）のために確保され得る。そのような状況下で、この血圧計によれば、上記第２側壁部の比較的広い領域（面積）を振動させて、外部へ音波を発することができる。したがって、音波による通信状態を良好に保つことができる。 Since the blood pressure monitor of this disclosure is equipped with the above-mentioned biometric information measuring device, it is possible to communicate with an external terminal equipped with a microphone via sound waves. Further, in this sphygmomanometer, a pump for supplying a fluid for compressing the measurement site is provided inside the accommodation space, and an air tube connection port for supplying the fluid from the pump to the outside of the housing is provided. It is provided on the first side wall portion that defines one of the four directions of the accommodation space. Therefore, if the holding member is fixed to the inner surface of the first side wall portion and the first side wall portion is vibrated by the vibrating member (or piezoelectric buzzer) held by the holding member, the first side wall portion is vibrated. The vibration transmission state (that is, the communication state) may be deteriorated. Therefore, in this sphygmomanometer, the holding member is fixed to the inner surface of the second side wall portion that defines the other direction different from the one position among the four directions of the accommodation space. By not arranging the air tube connection port and other components of the sphygmomanometer in the second side wall portion, a relatively large area (area) can be secured for vibration (and therefore sound wave communication). Under such circumstances, according to this sphygmomanometer, a relatively wide area (area) of the second side wall portion can be vibrated to emit sound waves to the outside. Therefore, it is possible to maintain a good communication state by sound waves.
　以上より明らかなように、この開示の生体情報測定装置および血圧計によれば、ハウジングをなす側壁部の内面に振動部材を固定して側壁部を振動させることにより、音波による通信状態を良好に保つことができる。 As is clear from the above, according to the biological information measuring device and the sphygmomanometer of the present disclosure, by fixing the vibrating member to the inner surface of the side wall portion forming the housing and vibrating the side wall portion, the communication state by sound waves is improved. Can be kept.

　図１は、この発明の生体情報測定装置の一実施形態としての卓上式血圧計１の外観を示している。図２は、血圧計１の外観を、図１におけるのとは略反対方向から見たところを示している。この血圧計１は、テーブル５００（図１参照）等の水平面上に載置され、マイクロフォンを備えた外部端末（図示せず）と音波（超音波を含む。）を介して通信を行う仕様になっている。 FIG. 1 shows the appearance of the desktop sphygmomanometer 1 as an embodiment of the biological information measuring device of the present invention. FIG. 2 shows the appearance of the sphygmomanometer 1 as viewed from a direction substantially opposite to that in FIG. The sphygmomanometer 1 is placed on a horizontal surface such as a table 500 (see FIG. 1) and communicates with an external terminal (not shown) equipped with a microphone via sound waves (including ultrasonic waves). It has become.
　図１、図２によって分かるように、血圧計１の筐体であるハウジング１０は、正面パネルをなすように面状に延在する第１壁部としての上壁（上ハウジング）１１と、上壁１１に対向しかつ面状に延在する第２壁部としての底壁１２と、上壁１１および底壁１２に交差して延在する側壁部１３Ｓとを備えている。これらの上壁１１と底壁１２と側壁部１３Ｓとによって、図３に示すように、ハウジング１０の内部に収容空間４００を画定している。側壁部１３Ｓは、収容空間４００の四方位（前後左右の方位）をそれぞれ画定する前側壁１４、後側壁１７、左側壁１５、右側壁１６を有している。この例では、底壁１２と側壁部１３Ｓとは、合成樹脂の一体成形により、下ハウジング１３として一体に構成されている。上壁１１は、下ハウジング１３とは別体として構成され、下ハウジング１３（特に、側壁部１３Ｓ）に対して着脱可能になっている。 As can be seen from FIGS. 1 and 2, the housing 10 which is the housing of the sphygmomanometer 1 has an upper wall (upper housing) 11 as a first wall portion extending in a plane so as to form a front panel, and an upper wall (upper housing) 11. It includes a bottom wall 12 as a second wall portion that faces the wall 11 and extends in a plane shape, and a side wall portion 13S that intersects the upper wall 11 and the bottom wall 12 and extends. As shown in FIG. 3, the accommodation space 400 is defined inside the housing 10 by the upper wall 11, the bottom wall 12, and the side wall portion 13S. The side wall portion 13S has a front side wall 14, a rear side wall 17, a left side wall 15, and a right side wall 16 that define four directions (front-back, left-right directions) of the accommodation space 400, respectively. In this example, the bottom wall 12 and the side wall portion 13S are integrally formed as the lower housing 13 by integrally molding a synthetic resin. The upper wall 11 is configured as a separate body from the lower housing 13, and is removable from the lower housing 13 (particularly, the side wall portion 13S).
　図１、図２によって分かるように、この例では、上壁１１は、前方から後方に向かうにつれて次第に高くなるように水平面に対して約２５°傾斜して延在する傾斜面になっている。底壁１２は、概ね平坦面になっているが、底壁１２の後縁部１２Ｂは、前方から後方に向かうにつれて次第に高くなるように水平面に対して約２５°傾斜した傾斜面になっている。前側壁１４と後側壁１７は、下から上に向かうにつれて次第に前になるように鉛直面に対してそれぞれ約３０°、約２０°傾斜した傾斜面になっている。左側壁１５、右側壁１６は、それぞれ下から上に向かうにつれて略鉛直に立ち上がる鉛直面になっている。 As can be seen from FIGS. 1 and 2, in this example, the upper wall 11 is an inclined surface extending at an inclination of about 25 ° with respect to the horizontal plane so as to gradually increase from the front to the rear. The bottom wall 12 has a substantially flat surface, but the trailing edge portion 12B of the bottom wall 12 has an inclined surface inclined by about 25 ° with respect to the horizontal plane so as to gradually increase from the front to the rear. .. The front side wall 14 and the rear side wall 17 are inclined surfaces that are inclined by about 30 ° and about 20 ° with respect to the vertical plane so as to gradually move forward from the bottom to the top. The left side wall 15 and the right side wall 16 are vertically facing each other so as to rise substantially vertically from the bottom to the top.
　図１に示すように、この例では、上壁１１には、ユーザが血圧計１に指示を入力するための操作部５２と、血圧に関する情報を表示する表示器５０とが設けられている。操作部５２は、ユーザが血圧測定のオンオフを指示するための測定／停止スイッチ５２Ａと、血圧計１の記憶部（図示しないが、収容空間４００内に配置されている）に記憶されている過去の血圧測定結果を呼び出すためのメモリスイッチ５２Ｂとを含んでいる。表示器５０は、血圧に関する情報として、最高血圧、最低血圧、脈拍数などを表示する。 As shown in FIG. 1, in this example, the upper wall 11 is provided with an operation unit 52 for the user to input an instruction to the sphygmomanometer 1 and a display 50 for displaying information on blood pressure. The operation unit 52 has a measurement / stop switch 52A for instructing the user to turn on / off the blood pressure measurement, and a past stored in a storage unit (not shown, but arranged in the accommodation space 400) of the sphygmomanometer 1. It includes a memory switch 52B for recalling the blood pressure measurement result of the above. The display 50 displays the systolic blood pressure, the diastolic blood pressure, the pulse rate, and the like as information on the blood pressure.
　また、この例では、第１側壁部としての左側壁１５に、エアチューブ接続口としてのエアコネクタ３９と、このエアコネクタ３９に取り付けられたエアプラグ３８とが配置されている。これらのエアコネクタ３９とエアプラグ３８とを介して、収容空間４００内部に配置されたポンプ（図示せず）からの空気（流体）がハウジング１０の外部、この例では図示しない血圧測定用カフへ供給される。これにより、血圧測定用カフによって被測定部位（例えば、上腕）が圧迫され、血圧測定が行われる。 Further, in this example, the air connector 39 as the air tube connection port and the air plug 38 attached to the air connector 39 are arranged on the left side wall 15 as the first side wall portion. Through these air connectors 39 and air plugs 38, air (fluid) from a pump (not shown) arranged inside the accommodation space 400 is supplied to the outside of the housing 10, a blood pressure measuring cuff (not shown in this example). Will be done. As a result, the blood pressure measurement cuff presses the area to be measured (for example, the upper arm), and the blood pressure is measured.
　図２に示すように、この例では、後側壁１７に、ＤＣジャック５３が配置されている。このＤＣジャック５３には、ハウジング１０の外部からＤＣ電圧（例えば、ＤＣ６Ｖ）が供給される。 As shown in FIG. 2, in this example, the DC jack 53 is arranged on the rear side wall 17. A DC voltage (for example, DC6V) is supplied to the DC jack 53 from the outside of the housing 10.
　また、この例では、底壁１２において、略中央に略矩形の電池蓋１４０が設けられ、また、四隅に短円柱状のゴム脚１８１，１８２，１８３，１８４が設けられている。ハウジング１０から電池蓋１４０が取り外された状態で、収容空間４００内に配置された電池収容部（図示せず）へ外部から電池を入れたり、逆に出したりすることが可能になっている。ハウジング１０に電池蓋１４０が取り付けられた状態では、電池蓋１４０はフック１４１で底壁１２に係合して、電池収容部に収容された電池がハウジング１０から脱落するのを防止する。ゴム脚１８１，１８２，１８３，１８４は、ハウジング１０がテーブル５００等の水平面上に置かれたとき、ハウジング１０の姿勢を維持する。 Further, in this example, in the bottom wall 12, a substantially rectangular battery lid 140 is provided in the substantially center, and short columnar rubber legs 181, 182, 183, 184 are provided at the four corners. With the battery cover 140 removed from the housing 10, it is possible to insert and remove the battery from the outside into the battery accommodating portion (not shown) arranged in the accommodating space 400. When the battery lid 140 is attached to the housing 10, the battery lid 140 engages with the bottom wall 12 with the hook 141 to prevent the battery housed in the battery housing from falling out of the housing 10. The rubber legs 181, 182, 183, 184 maintain the posture of the housing 10 when the housing 10 is placed on a horizontal surface such as a table 500.
　分かるように、この例では、ハウジング１０の前側壁１４と右側壁１６には、血圧測定のための本来の構成部品が配置されていない。前側壁１４よりも右側壁１６の方が広い面積を占めているので、右側壁１６を用いれば、比較的広い領域（面積）が振動（したがって、音波通信）のために確保され得る。 As can be seen, in this example, the original components for blood pressure measurement are not arranged on the front side wall 14 and the right side wall 16 of the housing 10. Since the right side wall 16 occupies a larger area than the front side wall 14, a relatively large area (area) can be reserved for vibration (and therefore sound wave communication) by using the right side wall 16.
　（実施例１）
　そこで、この例では、図３に示すように、第２側壁部としての右側壁１６の内面１６ｉに保持部材設置部７０が設けられ、この保持部材設置部７０に、振動部材（後述の圧電ブザー４０）を保持した状態の保持部材６０が固定されている。右側壁１６の内面１６ｉとは、右側壁１６の両面（内面１６ｉと外面１６ｏ）のうち、ハウジング１０の内部（収容空間４００）の側に向いた面を指す。保持部材６０は、保持部材設置部７０に、振動部材の振動を右側壁１６に伝達させる態様で固定されている。 (Example 1)
Therefore, in this example, as shown in FIG. 3, a holding member installation portion 70 is provided on the inner surface 16i of the right side wall 16 as the second side wall portion, and the holding member installation portion 70 is provided with a vibrating member (piezoelectric buzzer described later). The holding member 60 in the state of holding 40) is fixed. The inner surface 16i of the right side wall 16 refers to a surface of both surfaces (inner surface 16i and outer surface 16o) of the right side wall 16 facing the inside (accommodation space 400) of the housing 10. The holding member 60 is fixed to the holding member installation portion 70 in such a manner that the vibration of the vibrating member is transmitted to the right side wall 16.
　具体的には、図４（Ａ）と図４（Ｂ）は、図３における保持部材設置部７０の近傍（破線１６ｘで示す領域）を拡大して、互いに別の方向から見たところを示している。また、図５は、ハウジング１０を前後方向に切断して、右側壁１６の内面１６ｉに設けられた保持部材設置部７０を、保持部材６０が固定された状態で示している。これらの図では、いずれも、保持部材６０に、振動部材としての後述の圧電ブザー４０が保持された状態にある。 Specifically, FIGS. 4 (A) and 4 (B) show an enlarged view of the vicinity of the holding member installation portion 70 (the region indicated by the broken line 16x) in FIG. 3 and viewed from different directions. ing.

On the contrary, the holding member 60 holding the piezoelectric buzzer 40 can be slid and fixed to the holding member installation portion 70 diagonally downward as indicated by the arrow A1 as one direction. The directions indicated by the arrows A1 and A2 are perpendicular to the upper edge 16e of the right side wall 16 and correspond to the direction along the inner surface 16i of the right side wall 16.

In this example, the holding member installation portion 70 is an integral component of the housing 10 (particularly, the right side wall 16). Specifically, the holding member installation portion 70 is provided on both sides (that is, left and right in FIGS. 7 (A) and 7 (B)) with respect to a direction perpendicular to the above one direction (slide insertion direction indicated by arrow A1 in FIG. 6). It has a pair of guide columns 71 and 72 arranged in the above and a stopper 75 that defines the end of the slide insertion. As shown in FIG. 7A, the guide column 71 projects substantially in a flat plate shape from the inner surface 16i of the right side wall 16 toward the inside of the housing 10 in a direction perpendicular to the upper edge 16e of the right side wall 16. It has an extending regulation plate portion 71A and a sub regulation plate portion 71B bent from an end portion of the regulation plate portion 71A (the end facing the inside of the housing 10) toward the guide column 72. ing. A recess 73 recessed from above to below is provided on the upper portion of the regulation plate portion 71A.

　図１０（Ａ）、図１０（Ｂ）、図１１（Ａ）～図１１（Ｆ）によって分かるように、保持部材６０は、略矩形の面状に延在する板部６１と、この板部６１の３辺（図１０（Ａ）における左辺、右辺、上辺）と一体に連なる枠部６２～６４とを有している。この保持部材６０は、合成樹脂の一体成形により作製されている。この例では、板部６１の、一方の板面（圧電ブザー４０の金属板４１の第二の面４１ｂに接触する板面）６１ａと、この一方の板面６１ａと反対側の他方の板面６１ｂとは、いずれも平坦面になっている。枠部６２～６４は、板部６１の左辺、右辺、上辺にそれぞれ対応する矩形板部６２，６３，６４を含んでいる。 As can be seen from FIGS. 10 (A), 10 (B), and 11 (A) to 11 (F), the holding member 60 includes a plate portion 61 extending in a substantially rectangular plane shape and the plate portion. It has frame portions 62 to 64 that are integrally connected with the three sides (left side, right side, and upper side in FIG. 10A) of 61. The holding member 60 is manufactured by integrally molding a synthetic resin. In this example, one plate surface (plate surface in contact with the second surface 41b of the metal plate 41 of the piezoelectric buzzer 40) 61a of the plate portion 61 and the other plate surface opposite to the one plate surface 61a. Both 61b and 61b are flat surfaces. The frame portions 62 to 64 include rectangular plate portions 62, 63, 64 corresponding to the left side, the right side, and the upper side of the plate portion 61, respectively.

It is provided. In contrast, the rectangular plate portion 64 projects at a position corresponding to the window 61f at the right end of the plate portion 61 toward the rectangular plate portion 62 facing the plate portion 61 in parallel with one plate surface 61a of the plate portion 61. The holding portion 66 is provided. These sandwiching portions 65 and 66 cooperate with one plate surface 61a of the plate portion 61 and are slidly inserted along one plate surface 61a of the plate portion 61 as shown in FIG. 10 (A). The piezoelectric buzzer 40 (metal plate 41) is guided, and the corresponding end portion of the peripheral edge portion of the slide-inserted piezoelectric buzzer 40 (metal plate 41) is sandwiched.

It is set to be substantially equal to the outer diameter D of 40 (metal plate 41). Further, the dimension of the gap between one plate surface 61a of the plate portion 61 and the sandwiching portions 65, 66 in the direction perpendicular to the plate surface 61a is metal so that the piezoelectric buzzer 40 (metal plate 41) can be sandwiched. It is slightly smaller than the thickness of the plate 41, and is set to about 0.38 mm in this example.
　矩形板部６２には、外（図１０（Ａ）における左方）へ向かって突起した凸部６７が設けられている。また、矩形板部６３には、凸部６７とは左右非対称に、外（図１０（Ａ）における右方）へ向かって突起した凸部６８が設けられている。これらの凸部６７，６８は、既述の保持部材設置部７０に保持部材６０がスライド挿入される過程で、及び、スライド挿入された状態で、それぞれ案内コラム７１，７２の凹部７３，７４（図７参照）に対応して略丁度嵌合するように設けられている。ここで、凸部６７，６８（したがって、凹部７３，７４）は互いに左右非対称になっている。したがって、保持部材設置部７０に対して保持部材６０が、表裏を間違えた状態でスライド挿入されるような事態が防止される。 The rectangular plate portion 62 is provided with a convex portion 67 projecting outward (to the left in FIG. 10A). Further, the rectangular plate portion 63 is provided with a convex portion 68 projecting outward (to the right in FIG. 10A) asymmetrically with the convex portion 67. These convex portions 67 and 68 are the recesses 73 and 74 of the guide columns 71 and 72, respectively, in the process of slide-inserting the holding member 60 into the holding member installation portion 70 described above and in the state of being slid-inserted. It is provided so as to be substantially fitted in accordance with (see FIG. 7). Here, the convex portions 67, 68 (thus, the concave portions 73, 74) are asymmetrical with each other. Therefore, it is possible to prevent the holding member 60 from being slid-inserted into the holding member installation portion 70 with the front and back sides wrong.
　なお、保持部材６０における矩形板部６２と矩形板部６４とが作るコーナーには、リード配線４３，４４を通すための切り欠き６９が設けられている。 A notch 69 for passing the lead wirings 43 and 44 is provided at the corner formed by the rectangular plate portion 62 and the rectangular plate portion 64 of the holding member 60.
　血圧計１の組立過程では、図１０（Ａ）中に矢印Ｂ２で示すように、保持部材６０に、圧電ブザー４０がスライド挿入して固定され、保持される。これにより、圧電ブザー４０の金属板４１の第二の面４１ｂが保持部材６０の板部６１の一方の板面６１ａに接触して、圧電ブザー４０の振動が保持部材６０の板部６１に伝達され得る状態になる。また、図６中に矢印Ａ１で示すように、保持部材設置部７０に、圧電ブザー４０を保持した状態の保持部材６０がスライド挿入される。すると、右側壁１６の内面１６ｉと一対の案内コラム７１，７２が、保持部材６０のスライド挿入方向に垂直な方向への動きを規制する。また、ストッパ７５が、保持部材６０に当接してスライド挿入を停止させ、保持部材６０の下方（図６中に矢印Ａ１で示した方向）への動きを規制する。また、規制リブ７６は、保持部材６０から、圧電ブザー４０が脱落するのを規制する。この状態では、保持部材６０の板部６１の他方の板面６１ｂが右側壁１６の内面１６ｉに接触する。さらに、図１に示したように、上壁１１が下ハウジング１３（特に、側壁部１３Ｓ）に対して取り付けられる。この状態では、保持部材６０の上面（矩形板部６４）が上壁１１の内面によって押さえられて、保持部材設置部７０から保持部材６０が上方（図６中に矢印Ａ２で示した方向）へ離脱するのが規制される。これにより、右側壁１６の内面１６ｉに設けられた保持部材設置部７０に、圧電ブザー４０を保持した状態の保持部材６０が固定される。なお、仮に上壁１１よる規制が無い場合であっても、保持部材６０の外面と、右側壁１６の内面１６ｉ、一対の案内コラム７１，７２との間の摩擦力によって、保持部材設置部７０から保持部材６０が離脱するのは抑制される。このようにして、血圧計１の完成状態では、右側壁１６の内面１６ｉに、保持部材６０が、圧電ブザー４０の振動を右側壁１６に伝達させる態様で固定される。 In the process of assembling the sphygmomanometer 1, as shown by the arrow B2 in FIG. 10 (A), the piezoelectric buzzer 40 is slid-inserted into the holding member 60 to be fixed and held. As a result, the second surface 41b of the metal plate 41 of the piezoelectric buzzer 40 comes into contact with one plate surface 61a of the plate portion 61 of the holding member 60, and the vibration of the piezoelectric buzzer 40 is transmitted to the plate portion 61 of the holding member 60. It will be in a state where it can be done. Further, as shown by an arrow A1 in FIG. 6, the holding member 60 in a state of holding the piezoelectric buzzer 40 is slide-inserted into the holding member installation portion 70. Then, the inner surface 16i of the right side wall 16 and the pair of guide columns 71 and 72 restrict the movement of the holding member 60 in the direction perpendicular to the slide insertion direction. Further, the stopper 75 abuts on the holding member 60 to stop the slide insertion, and restricts the downward movement of the holding member 60 (the direction indicated by the arrow A1 in FIG. 6). Further, the regulation rib 76 regulates the piezoelectric buzzer 40 from falling off from the holding member 60. In this state, the other plate surface 61b of the plate portion 61 of the holding member 60 comes into contact with the inner surface 16i of the right side wall 16. Further, as shown in FIG. 1, the upper wall 11 is attached to the lower housing 13 (particularly, the side wall portion 13S). In this state, the upper surface (rectangular plate portion 64) of the holding member 60 is pressed by the inner surface of the upper wall 11, and the holding member 60 moves upward (in the direction indicated by the arrow A2 in FIG. 6) from the holding member installation portion 70. Withdrawal is regulated. As a result, the holding member 60 in a state of holding the piezoelectric buzzer 40 is fixed to the holding member installation portion 70 provided on the inner surface 16i of the right side wall 16. Even if there is no regulation by the upper wall 11, the holding member installation portion 70 is caused by the frictional force between the outer surface of the holding member 60, the inner surface 16i of the right side wall 16, and the pair of guide columns 71 and 72. It is suppressed that the holding member 60 is separated from the holding member 60. In this way, in the completed state of the sphygmomanometer 1, the holding member 60 is fixed to the inner surface 16i of the right side wall 16 in such a manner that the vibration of the piezoelectric buzzer 40 is transmitted to the right side wall 16.
　したがって、この血圧計１では、圧電ブザー４０が制御部（図示せず）からリード配線４３，４４を介して電気信号を受けて振動すると、右側壁１６が振動して、ハウジング１０の外部へ音波が発せられる。つまり、右側壁１６の比較的広い領域（面積）を振動させて、外部へ音波を発することができる。これにより、マイクロフォンを備えた外部端末と音波を介して通信が行われる。典型的な使用態様として、ハウジング１０がテーブル５００等の水平面上に置かれる場合、音波による通信状態を良好に保つことができる。 Therefore, in this sphygmomanometer 1, when the piezoelectric buzzer 40 receives an electric signal from the control unit (not shown) via the lead wirings 43 and 44 and vibrates, the right side wall 16 vibrates and a sound wave is emitted to the outside of the housing 10. Is emitted. That is, a relatively wide area (area) of the right side wall 16 can be vibrated to emit sound waves to the outside. As a result, communication is performed with an external terminal equipped with a microphone via sound waves. As a typical usage mode, when the housing 10 is placed on a horizontal surface such as a table 500, a good communication state by sound waves can be maintained.
　（変形例１）
　図１２（Ａ）、図１２（Ｂ）は、それぞれ上記保持部材６０を変形した保持部材１６０を、それぞれ図９（Ｃ）、図９（Ｆ）に対応する状態で示している。なお、以下の各変形例の説明では、実施例１における構成要素と同じ構成要素には同じ符号を付し、実施例１における構成要素に対して変形された構成要素には順次１００ずつ増加した符号を付して、詳細な説明を省略する。 (Modification example 1)
12 (A) and 12 (B) show the holding member 160, which is a modification of the holding member 60, in a state corresponding to FIGS. 9 (C) and 9 (F), respectively. In the following description of each modification, the same components as the components in the first embodiment are designated by the same reference numerals, and the components deformed with respect to the components in the first embodiment are sequentially increased by 100. Reference numerals will be given and detailed description thereof will be omitted.
　上の例のように、底壁１２と側壁部１３Ｓとが下ハウジング１３として一体成形される場合、金型から成形品を取出し易くするために、金型のキャビティやコアに抜き勾配がつけられることがある。それに応じて、図１２（Ｃ）中に例示するように、右側壁１１６の内面１１６ｉは、上壁１１から底壁１２へ向かって傾斜または湾曲した形状を有することになる。図１２（Ｃ）（右側壁１１６の前側壁１４に対して略平行な断面を、前方から後方へ向かって見たところを示す）の例では、右側壁１１６の内面１１６ｉが湾曲した形状を有している。ここで、仮に板部６１の他方の板面６１ｂが単なる平坦面であったとすると、板部６１の他方の板面６１ｂと右側壁１１６の内面１１６ｉとの間に隙間が生じて、圧電ブザー４０の振動が、ハウジング１０の右側壁１１６へ伝わり難くなる。 When the bottom wall 12 and the side wall portion 13S are integrally molded as the lower housing 13 as in the above example, a draft is formed in the cavity or core of the mold in order to facilitate the removal of the molded product from the mold. Sometimes. Accordingly, as illustrated in FIG. 12C, the inner surface 116i of the right side wall 116 will have a shape that is inclined or curved from the upper wall 11 to the bottom wall 12. In the example of FIG. 12C (showing a cross section substantially parallel to the front side wall 14 of the right side wall 116 viewed from the front to the rear), the inner surface 116i of the right side wall 116 has a curved shape. doing. Here, assuming that the other plate surface 61b of the plate portion 61 is a mere flat surface, a gap is generated between the other plate surface 61b of the plate portion 61 and the inner surface 116i of the right side wall 116, and the piezoelectric buzzer 40 Vibration is less likely to be transmitted to the right side wall 116 of the housing 10.
　そこで、この変形例１の保持部材１６０では、右側壁１１６の内面１１６ｉが上壁１１から底壁１２へ向かって傾斜または湾曲した特定の形状を有する場合に、板部６１の他方の板面６１ｂが、右側壁１１６の内面１１６ｉに沿った形状を有するものとする。例えば、図１２（Ａ）、図１２（Ｂ）に示すように、板部６１の他方の板面６１ｂの一部６１ｂｘが右側壁１１６の内面１１６ｉに向かって***し湾曲した形状を有するものとする。図１２（Ｂ）中の符号６１ｂｘは、板面６１ｂのうち左右方向に関して***した範囲を示している。 Therefore, in the holding member 160 of the modified example 1, when the inner surface 116i of the right side wall 116 has a specific shape inclined or curved from the upper wall 11 toward the bottom wall 12, the other plate surface 61b of the plate portion 61 However, it is assumed that the right side wall 116 has a shape along the inner surface 116i. For example, as shown in FIGS. 12A and 12B, a part 61bx of the other plate surface 61b of the plate portion 61 has a shape that is raised and curved toward the inner surface 116i of the right side wall 116. do. Reference numeral 61bx in FIG. 12B indicates a raised range of the plate surface 61b in the left-right direction.
　これにより、図１２（Ｃ）に例示するように、板部６１の他方の板面６１ｂ（正確には、一部６１ｂｘ）と右側壁１１６の内面１１６ｉとが密接して、圧電ブザー４０の振動が、ハウジング１０の右側壁１１６へ伝わり易くなる。この結果、音波による通信状態を良好に保つことができる。 As a result, as illustrated in FIG. 12C, the other plate surface 61b (to be exact, a part 61bx) of the plate portion 61 and the inner surface 116i of the right side wall 116 are in close contact with each other, and the piezoelectric buzzer 40 vibrates. However, it is easily transmitted to the right side wall 116 of the housing 10. As a result, the communication state by sound waves can be kept good.
　（変形例２）
　図１３（Ａ）、図１３（Ｂ）は、それぞれ上記保持部材６０を変形した別の保持部材２６０を、それぞれ図９（Ｆ）、図９（Ａ）に対応する状態で示している。 (Modification 2)
13 (A) and 13 (B) show another holding member 260 obtained by deforming the holding member 60, respectively, in a state corresponding to FIGS. 9 (F) and 9 (A), respectively.
　図１３（Ａ）、図１３（Ｂ）に示すように、この変形例２の保持部材２６０では、板部６１が、一方の板面６１ａから他方の板面６１ｂまで板厚方向に貫通した開口部６１ｇを有している。この例では、開口部６１ｇは、左右方向に関して圧電ブザー４０の圧電素子層４２が略占める範囲、かつ上下方向に関して板部６１の下端から矩形板部６４に達する範囲にわたって、略矩形状に開口している。 As shown in FIGS. 13 (A) and 13 (B), in the holding member 260 of the modified example 2, the plate portion 61 penetrates from one plate surface 61a to the other plate surface 61b in the plate thickness direction. It has a portion 61 g. In this example, the opening 61g opens substantially in a rectangular shape over a range occupied by the piezoelectric element layer 42 of the piezoelectric buzzer 40 in the horizontal direction and a range reaching from the lower end of the plate portion 61 to the rectangular plate portion 64 in the vertical direction. ing.
　一方、図１３（Ｃ）（右側壁１６の上壁１１に対して略平行な断面を、図６中の矢印Ａ１またはＡ２に沿って見たところを示す）中に示すように、右側壁１６の一部１６ｂｘが内側へ向かって窪んで、圧電ブザー４０の金属板４１の第二の面４１ｂに向けて右側壁１６の内面１６ｉの一部１６ｉｘが突出した形状を有している。これにより、板部６１が板厚（一方の板面６１ａと他方の板面６１ｂとの間の寸法）を有していても、血圧計１の完成状態では、金属板４１の第二の面４１ｂが開口部６１ｇを介して右側壁１６の内面１６ｉ（正確には、一部１６ｉｘ）に確実に接触するようになっている。 On the other hand, as shown in FIG. 13 (C) (a cross section substantially parallel to the upper wall 11 of the right side wall 16 is shown along the arrows A1 or A2 in FIG. 6), the right side wall 16 A part of 16bx is recessed inward, and a part of 16i of the inner surface 16i of the right side wall 16 projects toward the second surface 41b of the metal plate 41 of the piezoelectric buzzer 40. As a result, even if the plate portion 61 has a plate thickness (dimension between one plate surface 61a and the other plate surface 61b), the second surface of the metal plate 41 is in the completed state of the sphygmomanometer 1. The 41b is ensured to come into contact with the inner surface 16i (more precisely, a part of 16ix) of the right side wall 16 through the opening 61g.
　この結果、この血圧計１では、圧電ブザー４０の振動が右側壁１６に直接的に伝達される。したがって、振動の伝達効率が高まって、音波による通信状態を良好に保つことができる。 As a result, in this sphygmomanometer 1, the vibration of the piezoelectric buzzer 40 is directly transmitted to the right side wall 16. Therefore, the transmission efficiency of vibration is increased, and the communication state by sound waves can be kept good.
　（変形例３）
　図１４（Ａ１）、図１４（Ａ２）は、それぞれ上記保持部材６０を変形したさらに別の保持部材３６０を、それぞれ図９（Ｄ）、図９（Ａ）に対応する状態で示している。図１４（Ｂ１）、図１４（Ｂ２）は、変形例３の保持部材３６０が装着されるべき保持部材設置部３７０を、それぞれ保持部材３６０のスライド挿入方向（図６中に矢印Ａ１で示した方向）に沿って上方から見たところ、収容空間４００の内側から正対して見たところを示している。 (Modification example 3)
14 (A1) and 14 (A2) show still another holding member 360 obtained by modifying the holding member 60, respectively, in a state corresponding to FIGS. 9 (D) and 9 (A), respectively. 14 (B1) and 14 (B2) show the holding member installation portion 370 to which the holding member 360 of the modified example 3 should be mounted, respectively, in the slide insertion direction of the holding member 360 (arrow A1 in FIG. 6). When viewed from above along the direction), it shows a view facing directly from the inside of the accommodation space 400.
　図１４（Ａ１）、図１４（Ａ２）に示すように、この変形例３の保持部材３６０では、上記保持部材６０における凸部６７，６８に代えて、矩形板部６２に、外（図１４（Ａ１）、図１４（Ａ２）における左方）へ向かって突起した、弾性を示す弾性部としての略平板状の弾性板３６７が一体に設けられている。また、矩形板部６３には、弾性板３６７と左右対称に、外（図１４（Ａ１）、図１４（Ａ２）における右方）へ向かって突起した、弾性を示す弾性部としての略平板状の弾性板３６８が一体に設けられている。 As shown in FIGS. 14 (A1) and 14 (A2), in the holding member 360 of the modified example 3, instead of the convex portions 67 and 68 in the holding member 60, the rectangular plate portion 62 is outside (FIG. 14). A substantially flat plate-shaped elastic plate 367 as an elastic portion exhibiting elasticity is integrally provided, which protrudes toward (A1) and left side in FIG. 14 (A2). Further, the rectangular plate portion 63 has a substantially flat plate shape as an elastic portion exhibiting elasticity, which protrudes outward (to the right in FIGS. 14 (A1) and 14 (A2)) symmetrically with the elastic plate 367. The elastic plate 368 of the above is integrally provided.
　図１４（Ａ１）によって分かるように、これらの弾性板３６７，３６８の根元部３６７ｎ，３６８ｎは、それぞれ矩形板部６２，６３の略中央に位置している。板部６１の他方の板面６１ｂと弾性板３６７，３６８の根元部３６７ｎ，３６８ｎとの間の距離は符号ｙ０ｍで表されている。弾性板３６７，３６８は、それぞれ、自然状態で矩形板部６２，６３に対して傾斜しており、弾性板３６７，３６８の先端部３６７ｓ，３６８ｓは、図１４（Ａ１）、図１４（Ａ２）における上下方向に関して、根元部３６７ｎ，３６８ｎよりも他方の板面６１ｂに近い位置にある。弾性板３６７，３６８の厚さは符号ｔ１で表されている。 As can be seen from FIG. 14 (A1), the root portions 367n and 368n of these elastic plates 367 and 368 are located substantially in the center of the rectangular plate portions 62 and 63, respectively. The distance between the other plate surface 61b of the plate portion 61 and the root portions 367n and 368n of the elastic plates 367 and 368 is represented by the reference numeral y0m. The elastic plates 367 and 368 are naturally inclined with respect to the rectangular plate portions 62 and 63, respectively, and the tip portions 367s and 368s of the elastic plates 367 and 368 are shown in FIGS. 14 (A1) and 14 (A2), respectively. In the vertical direction in the above, the position is closer to the other plate surface 61b than the root portions 367n and 368n. The thickness of the elastic plates 367 and 368 is represented by the reference numeral t1.
　図１４（Ｂ１）、図１４（Ｂ２）に示すように、この変形例３では、保持部材設置部３７０は、上記スライド挿入方向（図６中に矢印Ａ１で示す）に垂直な方向に関して両側（すなわち図１４（Ｂ１）、図１４（Ｂ２）において左右）に配置された一対の案内コラム３７１，３７２と、その方向に関して案内コラム３７１，３７２間の位置に設けられた一対の押さえリブ３７７，３７８と、スライド挿入の終端を画定するストッパ３７５と、規制リブ３７６とを有している。 As shown in FIGS. 14 (B1) and 14 (B2), in this modification 3, the holding member installation portion 370 is located on both sides (indicated by an arrow A1 in FIG. 6) on both sides (indicated by an arrow A1 in FIG. 6). That is, a pair of guide columns 371 and 372 arranged on the left and right sides in FIGS. 14 (B1) and 14 (B2), and a pair of holding ribs 377 and 378 provided at positions between the guide columns 371 and 372 in that direction. And a stopper 375 that defines the end of the slide insertion, and a regulating rib 376.
　案内コラム３７１，３７２は、それぞれ、右側壁１６の内面１６ｉからハウジング１０の内部へ向かって厚い板状に突起し、上記スライド挿入方向に沿って延在している。さらに、案内コラム３７１，３７２の互いに対向する面には、それぞれ断面凹状の案内溝３７１ｄ，３７２ｄが、上記スライド挿入方向に沿って設けられている。 The guide columns 371 and 372 project from the inner surface 16i of the right side wall 16 toward the inside of the housing 10 in a thick plate shape, and extend along the slide insertion direction. Further, on the surfaces of the guide columns 371 and 372 facing each other, guide grooves 371d and 372d having a concave cross section are provided along the slide insertion direction, respectively.
　案内コラム３７１，３７２間の距離、より正確には、案内溝３７１ｄ，３７２ｄの底の間の距離ｘ１２は、案内溝３７１ｄ，３７２ｄにそれぞれ弾性板３６７，３６８の先端部３６７ｓ，３６８ｓがスライド挿入され得るように、弾性板３６７，３６８の先端部３６７ｓ，３６８ｓ間の寸法Ｌ１（図１４（Ａ１）参照）よりも若干だけ大きく設定されている。図１４（Ｂ１）によって分かるように、案内溝３７１ｄ，３７２ｄの一側面（図１４（Ｂ１）において下側の側面）３７１ｄ１，３７２ｄ１は、互いに対して開くように傾斜した傾斜面になっている。これにより、案内溝３７１ｄ，３７２ｄ内に、弾性板３６７，３６８の傾斜した先端部３６７ｓ，３６８ｓが挿入され易くなっている。 The distance between the guide columns 371 and 372, or more accurately, the distance x12 between the bottoms of the guide grooves 371d and 372d, is such that the tips 367s and 368s of the elastic plates 367 and 368 are slid into the guide grooves 371d and 372d, respectively. As obtained, the dimension L1 between the tip portions 367s and 368s of the elastic plates 367 and 368 (see FIG. 14 (A1)) is set to be slightly larger than the dimension L1. As can be seen from FIG. 14 (B1), one side surface (lower side surface in FIG. 14 (B1)) 371d1 and 372d1 of the guide grooves 371d and 372d are inclined surfaces inclined so as to open with respect to each other. As a result, the inclined tip portions 367s and 368s of the elastic plates 367 and 368 are easily inserted into the guide grooves 371d and 372d.
　押さえリブ３７７，３７８は、それぞれ底壁１２に立設され、底壁１２から図１４（Ｂ２）における上方へ向かって、互いに平行に略平板状に延在している。この例では、底壁１２と側壁部１３Ｓとが下ハウジング１３として一体に構成されていることから、押さえリブ３７７，３７８は、底壁１２を介して右側壁１６と一体の構成要素になっている。 The holding ribs 377 and 378 are erected on the bottom wall 12, respectively, and extend from the bottom wall 12 upward in FIG. 14 (B2) in a substantially flat plate shape in parallel with each other. In this example, since the bottom wall 12 and the side wall portion 13S are integrally formed as the lower housing 13, the pressing ribs 377 and 378 become an integral component with the right side wall 16 via the bottom wall 12. There is.
　押さえリブ３７７，３７８間の距離ｘ１１は、これらの押さえリブ３７７，３７８によって弾性板３６７，３６８の根元部３６７ｎ，３６８ｎが押えられ得るように、根元部３６７ｎ，３６８ｎ間の寸法と略等しく設定されている。図１４（Ｂ１）によって分かるように、押さえリブ３７７，３７８の、右側壁１６の内面１６ｉに面する側の端面３７７ｆ，３７８ｆは丸く形成されている。これにより、これらの端面３７７ｆ，３７８ｆに沿って弾性板３６７，３６８の根元部３６７ｎ，３６８ｎが摺動し易くなっている。 The distance x11 between the pressing ribs 377 and 378 is set to be substantially equal to the dimension between the root portions 367n and 368n so that the root portions 367n and 368n of the elastic plates 367 and 368 can be pressed by these pressing ribs 377 and 378. ing. As can be seen from FIG. 14 (B1), the end faces 377f and 378f of the pressing ribs 377 and 378 on the side facing the inner surface 16i of the right side wall 16 are formed in a round shape. As a result, the root portions 367n and 368n of the elastic plates 367 and 368 can easily slide along the end faces 377f and 378f.
　この例では、案内コラム３７１，３７２における右側壁１６の内面１６ｉと案内溝３７１ｄ，３７２ｄとの間の距離ｙ１１は、保持部材３６０における板部６１の他方の板面６１ｂと弾性板３６７，３６８の根元部３６７ｎ，３６８ｎとの間の距離ｙ０ｍ（図１４（Ａ１）参照）と略等しく設定されている。また、右側壁１６の内面１６ｉと押さえリブ３７７，３７８の端面３７７ｆ，３７８ｆとの間の距離ｙ１２については、右側壁１６の内面１６ｉに保持部材３６０を押し付けるために、ｙ１２≒ｙ０ｍ＋ｔ１に設定されている。 In this example, the distance y11 between the inner surface 16i of the right side wall 16 and the guide grooves 371d and 372d in the guide columns 371 and 372 is the distance y11 between the other plate surface 61b of the plate portion 61 and the elastic plates 367 and 368 of the holding member 360. The distance between the root portions 367n and 368n is set to be substantially equal to the distance y0m (see FIG. 14 (A1)). Further, the distance y12 between the inner surface 16i of the right side wall 16 and the end surfaces 377f and 378f of the pressing ribs 377 and 378 is set to y12≈y0m + t1 in order to press the holding member 360 against the inner surface 16i of the right side wall 16. There is.
　ストッパ３７５は、実施例１におけるストッパ７５と同様に構成されており、スライド挿入される保持部材３６０に当接して、保持部材３６０のスライド挿入を停止させる。また、規制リブ３７６は、実施例１におけるストッパ７５と同様に構成されており、保持部材設置部３７０に保持された保持部材３６０から、圧電ブザー４０が脱落するのを規制する。 The stopper 375 has the same configuration as the stopper 75 in the first embodiment, and comes into contact with the holding member 360 to be slid-inserted to stop the slide insertion of the holding member 360. Further, the regulation rib 376 is configured in the same manner as the stopper 75 in the first embodiment, and regulates the piezoelectric buzzer 40 from falling off from the holding member 360 held by the holding member installation portion 370.
　図１５（Ａ１）、図１５（Ａ２）～図１５（Ｂ１）、図１５（Ｂ２）は、変形例３の保持部材３６０が、図１４（Ｂ１）、図１４（Ｂ２）に示した保持部材設置部３７０に装着される過程を示している。なお、図１５（Ａ１）、図１５（Ａ２）の視方向および視野は、それぞれ図１４（Ｂ１）、図１４（Ｂ２）におけるのと一致している。この点、図１５（Ｂ１）、図１５（Ｂ２）の視方向および視野も同様である。 In FIGS. 15 (A1), 15 (A2) to 15 (B1), and 15 (B2), the holding member 360 of the modified example 3 is the holding member shown in FIGS. 14 (B1) and 14 (B2). The process of being attached to the installation part 370 is shown. The viewing directions and visual fields of FIGS. 15 (A1) and 15 (A2) are the same as those in FIGS. 14 (B1) and 14 (B2), respectively. In this respect, the viewing direction and the visual field of FIGS. 15 (B1) and 15 (B2) are the same.
　予め、圧電ブザー４０を保持した状態の保持部材３６０が用意される。このとき、保持部材３６０の弾性板３６７，３６８は、自然状態にあるものとする。 A holding member 360 in a state of holding the piezoelectric buzzer 40 is prepared in advance. At this time, the elastic plates 367 and 368 of the holding member 360 are assumed to be in a natural state.
　まず、図１５（Ａ１）、図１５（Ａ２）に示すように、上記スライド挿入方向（図６中に矢印Ａ１で示す）に沿って、保持部材３６０の弾性板３６７，３６８の先端部３６７ｓ，３６８ｓが、案内コラム３７１，３７２の案内溝３７１ｄ，３７２ｄに挿入される。すると、弾性板３６７，３６８の根元部３６７ｎ，３６８ｎが押さえリブ３７７，３７８の上端に当接して、保持部材３６０のスライド挿入は一旦停止する。 First, as shown in FIGS. 15 (A1) and 15 (A2), the tips of the elastic plates 367 and 368 of the holding member 360 are 367s, along the slide insertion direction (indicated by the arrow A1 in FIG. 6). The 368s are inserted into the guide grooves 371d and 372d of the guide columns 371 and 372. Then, the root portions 367n and 368n of the elastic plates 367 and 368 come into contact with the upper ends of the pressing ribs 377 and 378, and the slide insertion of the holding member 360 is temporarily stopped.
　次に、ユーザが手動または自動により、図１５（Ｂ１）中に矢印Ｃ１で示すように、保持部材３６０を右側壁１６の内面１６ｉに向かって押すと、弾性板３６７，３６８が変形して、弾性板３６７，３６８の根元部３６７ｎ，３６８ｎが押さえリブ３７７，３７８を回避することができる。このとき、弾性板３６７，３６８の根元部３６７ｎ，３６８ｎは押さえリブ３７７，３７８から押圧力Ｆ１，Ｆ２を受ける。これに伴って、保持部材３６０の板部６１の他方の板面６１ｂは、右側壁１６の内面１６ｉへ向けて付勢され、押し付けられる。 Next, when the user manually or automatically pushes the holding member 360 toward the inner surface 16i of the right side wall 16 as shown by the arrow C1 in FIG. 15 (B1), the elastic plates 367 and 368 are deformed. The root portions 367n and 368n of the elastic plates 367 and 368 can avoid the pressing ribs 377 and 378. At this time, the root portions 367n and 368n of the elastic plates 367 and 368 receive pressing pressures F1 and F2 from the pressing ribs 377 and 378. Along with this, the other plate surface 61b of the plate portion 61 of the holding member 360 is urged and pressed toward the inner surface 16i of the right side wall 16.
　次に、この状態で、図１５（Ｂ１）中に矢印Ｃ２で示すように、上記スライド挿入方向に沿って、保持部材３６０がスライド挿入される。弾性板３６７，３６８の根元部３６７ｎ，３６８ｎが押さえリブ３７７，３７８に摺接するとともに、板部６１の他方の板面６１ｂが右側壁１６の内面１６ｉに摺接しながら、保持部材３６０はスライド挿入される。そして、保持部材３６０がストッパ３７５に当接すると、保持部材３６０のスライド挿入は停止する。 Next, in this state, the holding member 360 is slide-inserted along the slide insertion direction as shown by the arrow C2 in FIG. 15 (B1). The holding member 360 is slid-inserted while the root portions 367n and 368n of the elastic plates 367 and 368 are in sliding contact with the pressing ribs 377 and 378, and the other plate surface 61b of the plate portion 61 is in sliding contact with the inner surface 16i of the right side wall 16. NS. Then, when the holding member 360 comes into contact with the stopper 375, the slide insertion of the holding member 360 is stopped.
　このようにして、保持部材設置部３７０に保持部材３６０が弾性板３６７，３６８の変形を伴ってスライド挿入された状態では、一対の案内コラム３７１，３７２が、保持部材３６０の図１５（Ｂ１）、図１５（Ｂ２）における左右方向への動きを規制する。また、右側壁１６の内面１６ｉと、押さえリブ３７７，３７８とが、保持部材３６０の右側壁１６の内面１６ｉに対して垂直な方向への動きを規制する。また、ストッパ３７５が、保持部材３６０の下方（図６中に矢印Ａ１で示した方向）への動きを規制する。また、規制リブ３７６は、保持部材３６０から、圧電ブザー４０が脱落するのを規制する。この状態では、保持部材３６０の板部６１の他方の板面６１ｂが右側壁１６の内面１６ｉへ向けて付勢され、押し付けられる。さらに、図１に示したように、上壁１１が下ハウジング１３（特に、側壁部１３Ｓ）に対して取り付けられる。この状態では、保持部材３６０の上面（矩形板部６４）が上壁１１の内面によって押さえられて、保持部材設置部３７０から保持部材３６０が上方（図６中に矢印Ａ２で示した方向）へ離脱するのが規制される。これにより、右側壁１６の内面１６ｉに設けられた保持部材設置部３７０に、圧電ブザー４０を保持した状態の保持部材３６０が固定される。なお、仮に上壁１１よる規制が無い場合であっても、主に保持部材３６０の板部６１の他方の板面６１ｂと右側壁１６の内面１６ｉとの間の摩擦力によって、保持部材設置部３７０から保持部材３６０が離脱するのは抑制される。このようにして、血圧計１の完成状態では、右側壁１６の内面１６ｉに、保持部材３６０が、圧電ブザー４０の振動を右側壁１６に伝達させる態様で固定される。 In this way, in a state where the holding member 360 is slide-inserted into the holding member installation portion 370 with the deformation of the elastic plates 367 and 368, the pair of guide columns 371 and 372 are attached to the holding member 360 in FIG. 15 (B1). , The movement in the left-right direction in FIG. 15 (B2) is regulated. Further, the inner surface 16i of the right side wall 16 and the pressing ribs 377 and 378 restrict the movement of the holding member 360 in the direction perpendicular to the inner surface 16i of the right side wall 16. Further, the stopper 375 regulates the downward movement of the holding member 360 (the direction indicated by the arrow A1 in FIG. 6). Further, the regulation rib 376 regulates the piezoelectric buzzer 40 from falling off from the holding member 360. In this state, the other plate surface 61b of the plate portion 61 of the holding member 360 is urged and pressed toward the inner surface 16i of the right side wall 16. Further, as shown in FIG. 1, the upper wall 11 is attached to the lower housing 13 (particularly, the side wall portion 13S). In this state, the upper surface (rectangular plate portion 64) of the holding member 360 is pressed by the inner surface of the upper wall 11, and the holding member 360 moves upward (in the direction indicated by the arrow A2 in FIG. 6) from the holding member installation portion 370. Withdrawal is regulated. As a result, the holding member 360 holding the piezoelectric buzzer 40 is fixed to the holding member installation portion 370 provided on the inner surface 16i of the right side wall 16. Even if there is no regulation by the upper wall 11, the holding member installation portion is mainly due to the frictional force between the other plate surface 61b of the plate portion 61 of the holding member 360 and the inner surface 16i of the right side wall 16. The detachment of the holding member 360 from the 370 is suppressed. In this way, in the completed state of the sphygmomanometer 1, the holding member 360 is fixed to the inner surface 16i of the right side wall 16 in such a manner that the vibration of the piezoelectric buzzer 40 is transmitted to the right side wall 16.
　この変形例３の血圧計１では、保持部材３６０の板部６１が右側壁１６の内面１６ｉへ向けて付勢され、押し付けられるので、圧電ブザー４０から右側壁１６の内面１６ｉへの振動の伝達効率が高まって、音波による通信状態をさらに良好に保つことができる。 In the sphygmomanometer 1 of the third modification, the plate portion 61 of the holding member 360 is urged and pressed toward the inner surface 16i of the right side wall 16, so that the vibration is transmitted from the piezoelectric buzzer 40 to the inner surface 16i of the right side wall 16. The efficiency is increased, and the communication state by sound waves can be maintained even better.
　（変形例４）
　図１６（Ａ１）、図１６（Ａ２）は、それぞれ上記保持部材６０を変形したさらに別の保持部材４６０を、それぞれ図９（Ｄ）、図９（Ａ）に対応する状態で示している。図１６（Ｂ１）、図１６（Ｂ２）は、変形例４の保持部材４６０が装着されるべき保持部材設置部４７０を、それぞれ保持部材４６０のスライド挿入方向（図６中に矢印Ａ１で示した方向）に沿って上方から見たところ、収容空間４００の内側から正対して見たところを示している。 (Modification example 4)
16 (A1) and 16 (A2) show still another holding member 460, which is a modification of the holding member 60, in a state corresponding to FIGS. 9 (D) and 9 (A), respectively. 16 (B1) and 16 (B2) show the holding member installation portion 470 to which the holding member 460 of the modified example 4 should be mounted, respectively, in the slide insertion direction of the holding member 460 (arrow A1 in FIG. 6). When viewed from above along the direction), it shows a view facing directly from the inside of the accommodation space 400.
　図１６（Ａ１）、図１６（Ａ２）に示すように、この変形例４の保持部材４６０では、上記保持部材６０における凸部６７，６８に代えて、矩形板部６２に、外（図１６（Ａ１）、図１６（Ａ２）における左方）へ向かって突起した、弾性を示す弾性部としての略平板状の弾性板４６７が一体に設けられている。また、矩形板部６３には、弾性板４６７と左右対称に、外（図１６（Ａ１）、図１６（Ａ２）における右方）へ向かって突起した、弾性を示す弾性部としての略平板状の弾性板４６８が一体に設けられている。 As shown in FIGS. 16 (A1) and 16 (A2), in the holding member 460 of the modified example 4, instead of the convex portions 67 and 68 in the holding member 60, the rectangular plate portion 62 is outside (FIG. 16). A substantially flat plate-shaped elastic plate 467 as an elastic portion exhibiting elasticity is integrally provided, which protrudes toward (A1) and left side in FIG. 16 (A2). Further, the rectangular plate portion 63 has a substantially flat plate shape as an elastic portion exhibiting elasticity, which protrudes outward (to the right in FIGS. 16 (A1) and 16 (A2)) symmetrically with the elastic plate 467. 468 elastic plates are integrally provided.
　図１６（Ａ１）によって分かるように、この変形例４の保持部材４６０では、変形例３の保持部材３６０に対して、弾性板４６７，４６８が矩形板部６２，６３に対して傾斜しておらず、矩形板部６２，６３に対して垂直に延在している点のみが異なっている。 As can be seen from FIG. 16A, in the holding member 460 of the modified example 4, the elastic plates 467 and 468 are inclined with respect to the rectangular plate portions 62 and 63 with respect to the holding member 360 of the modified example 3. The only difference is that they extend perpendicular to the rectangular plates 62 and 63.
　図１６（Ｂ１）、図１６（Ｂ２）に示すように、この変形例４では、保持部材設置部４７０は、保持部材４６０を受け得るように、上記スライド挿入方向（図６中に矢印Ａ１で示す）に垂直な方向に関して両側（すなわち図１６（Ｂ１）、図１６（Ｂ２）において左右）に配置された一対の案内コラム４７１，４７２と、スライド挿入の終端を画定するストッパ４７５と、規制リブ４７６とを有している。 As shown in FIGS. 16 (B1) and 16 (B2), in the modified example 4, the holding member installation portion 470 can receive the holding member 460 in the slide insertion direction (arrow A1 in FIG. 6). A pair of guide columns 471 and 472 arranged on both sides (ie, left and right in FIGS. 16 (B1) and 16 (B2)) in a direction perpendicular to (shown), a stopper 475 defining the end of the slide insertion, and a regulating rib. It has 476 and.
　案内コラム４７１，４７２は、それぞれ、それぞれ底壁１２に立設され、底壁１２から図１６（Ｂ２）における上方へ向かって、互いに平行に断面Ｌ字状に延在している。詳しくは、案内コラム４７１は、右側壁１６の内面１６ｉに対して垂直な方向に延在する（Ｌ字の短辺に相当する）規制板部４７１Ａと、この規制板部４７１Ａの端部（ハウジング１０の内部へ向かった端部）から案内コラム４７２へ向かって屈曲して設けられた（Ｌ字の長辺に相当する）サブ規制板部４７１Ｂとを有している。案内コラム４７２は、案内コラム４７１と左右対称に設けられ、右側壁１６の内面１６ｉに対して垂直な方向に延在する（Ｌ字の短辺に相当する）規制板部４７２Ａと、この規制板部４７２Ａの端部（ハウジング１０の内部へ向かった端部）から案内コラム４７１へ向かって屈曲して設けられた（Ｌ字の長辺に相当する）サブ規制板部４７２Ｂとを有している。この例では、底壁１２と側壁部１３Ｓとが下ハウジング１３として一体に構成されていることから、案内コラム４７１，４７２は、底壁１２を介して右側壁１６と一体の構成要素になっている。 The guide columns 471 and 472 are respectively erected on the bottom wall 12, and extend upward in FIG. 16 (B2) from the bottom wall 12 in an L-shaped cross section parallel to each other. Specifically, the guide column 471 has a regulation plate portion 471A extending in a direction perpendicular to the inner surface 16i of the right side wall 16 (corresponding to the short side of the L shape) and an end portion (housing) of the regulation plate portion 471A. It has a sub-regulatory plate portion 471B (corresponding to the long side of the L-shape) provided by being bent toward the guide column 472 from the end portion toward the inside of the 10. The guide column 472 is provided symmetrically with the guide column 471, and extends in a direction perpendicular to the inner surface 16i of the right side wall 16 (corresponding to the short side of the L shape), and the regulation plate portion 472A and the regulation plate. It has a sub-regulatory plate portion 472B (corresponding to the long side of the L shape) provided by bending from the end portion of the portion 472A (the end portion toward the inside of the housing 10) toward the guide column 471. .. In this example, since the bottom wall 12 and the side wall portion 13S are integrally formed as the lower housing 13, the guide columns 471 and 472 become an integral component with the right side wall 16 via the bottom wall 12. There is.
　案内コラム４７１，４７２の規制板部４７１Ａ，４７２Ａ間の距離ｘ２１は、図１６（Ｂ１）における左右方向の動きを規制できるように、保持部材４６０の弾性板４６７，４６８を除いた外寸法（図９（Ｄ）中に示すｘ０）と略等しく設定されている。一方、右側壁１６の内面１６ｉとサブ規制板部４７１Ｂ，４７２Ｂとの間の距離ｙ２１は、図１６（Ｂ１）における上下方向に関して保持部材４６０が余裕をもって挿入され得る（したがって、多少移動できる）ように、保持部材４６０の外寸法（図９（Ｃ）中に示すｙ０）よりも若干だけ大きく設定されている。 The distance x21 between the regulating plate portions 471A and 472A of the guide columns 471 and 472 has external dimensions (FIG. 4) excluding the elastic plates 467 and 468 of the holding member 460 so that the movement in the left-right direction in FIG. 16 (B1) can be regulated. It is set to be substantially equal to x0) shown in 9 (D). On the other hand, the distance y21 between the inner surface 16i of the right side wall 16 and the sub-regulatory plate portions 471B and 472B is such that the holding member 460 can be inserted with a margin (and therefore can be moved to some extent) in the vertical direction in FIG. 16 (B1). Is set to be slightly larger than the outer dimension of the holding member 460 (y0 shown in FIG. 9C).
　ストッパ４７５は、実施例１におけるストッパ７５と同様に構成されており、スライド挿入される保持部材４６０に当接して、保持部材４６０のスライド挿入を停止させる。また、規制リブ４７６は、実施例１におけるストッパ７５と同様に構成されており、保持部材設置部４７０に保持された保持部材４６０から、圧電ブザー４０が脱落するのを規制する。 The stopper 475 has the same configuration as the stopper 75 in the first embodiment, and comes into contact with the holding member 460 to be slid-inserted to stop the slide insertion of the holding member 460. Further, the regulation rib 476 is configured in the same manner as the stopper 75 in the first embodiment, and regulates the piezoelectric buzzer 40 from falling off from the holding member 460 held by the holding member installation portion 470.
　図１７（Ａ）は、上記ハウジング１０をなす上壁１１の構成要素としての一対の押さえリブ４７７，４７８の配置を、上壁１１に正対して上方から見たところを模式的に示している。図１７（Ｂ）は、それらの押さえリブ４７７，４７８を、図１７（Ａ）における右側方（矢印Ｒ１で示す）から見たところを示している。 FIG. 17A schematically shows the arrangement of a pair of pressing ribs 477,478 as components of the upper wall 11 forming the housing 10 as viewed from above facing the upper wall 11. .. FIG. 17B shows those holding ribs 477,478 viewed from the right side (indicated by arrow R1) in FIG. 17A.
　図１７（Ａ）、図１７（Ｂ）によって分かるように、押さえリブ４７７，４７８は、それぞれ上壁１１と一体に設けられ、上壁１１の内面１１ｉから下方へ向かって、互いに平行に直角三角形の平板状に突起している。これらの押さえリブ４７７，４７８は、血圧計１の完成状態では、保持部材設置部４７０へ向かって延びて、保持部材４６０の弾性板４６７，４６８を押えるために設けられている。 As can be seen from FIGS. 17 (A) and 17 (B), the holding ribs 477 and 478 are provided integrally with the upper wall 11, respectively, and are right triangles parallel to each other from the inner surface 11i of the upper wall 11 downward. It protrudes like a flat plate. In the completed state of the sphygmomanometer 1, these pressing ribs 477 and 478 extend toward the holding member installation portion 470 and are provided to press the elastic plates 467 and 468 of the holding member 460.
　図１７（Ａ）に示すように、押さえリブ４７７，４７８間の距離ｘ２２は、これらの押さえリブ４７７，４７８によって弾性板４６７，４６８が押えられ得るように、弾性板４６７，４６８の先端部４６７ｓ，４６８ｓ間の寸法Ｌ１よりも小さく、かつ、保持部材４６０の弾性板４６７，４６８を除いた外寸法（図９（Ｄ）中に示すｘ０）よりも大きく設定されている。図１７（Ａ）によって分かるように、押さえリブ４７７，４７８の右側壁１６の内面１６ｉに面する側の端面（直角三角形の斜面に相当する）４７７ｆ，４７８ｆは、丸く形成されている。これにより、これらの端面４７７ｆ，４７８ｆが弾性板４６７，４６８に対して摺動し易くなっている。 As shown in FIG. 17 (A), the distance x22 between the pressing ribs 477 and 478 is such that the tip portions 467s of the elastic plates 467 and 468 are such that the elastic plates 467 and 468 can be pressed by these pressing ribs 477 and 478. It is set to be smaller than the dimension L1 between 468s and larger than the outer dimension (x0 shown in FIG. 9D) excluding the elastic plates 467 and 468 of the holding member 460. As can be seen from FIG. 17A, the end faces (corresponding to the slope of a right triangle) 477f, 478f on the right side wall 16 of the pressing ribs 477,478 facing the inner surface 16i are formed in a round shape. This makes it easier for these end faces 477f and 478f to slide with respect to the elastic plates 467 and 468.
　図１８（Ａ１）、図１８（Ａ２）～図１８（Ｂ１）、図１８（Ｂ２）は、変形例４の保持部材４６０が、図１６（Ｂ１）、図１６（Ｂ２）に示した保持部材設置部４７０に装着される過程を示している。なお、図１８（Ａ１）、図１８（Ａ２）の視方向および視野は、それぞれ図１６（Ｂ１）、図１６（Ｂ２）におけるのと一致している。この点、図１８（Ｂ１）、図１８（Ｂ２）の視方向および視野も同様である。 In FIGS. 18 (A1), 18 (A2) to 18 (B1), and 18 (B2), the holding member 460 of the modified example 4 is the holding member shown in FIGS. 16 (B1) and 16 (B2). The process of being attached to the installation part 470 is shown. The viewing directions and visual fields of FIGS. 18 (A1) and 18 (A2) are the same as those in FIGS. 16 (B1) and 16 (B2), respectively. In this respect, the viewing direction and the visual field of FIGS. 18 (B1) and 18 (B2) are the same.
　予め、圧電ブザー４０を保持した状態の保持部材４６０が用意される。このとき保持部材４６０の弾性板４６７，４６８は、自然状態にあるものとする。 A holding member 460 in a state of holding the piezoelectric buzzer 40 is prepared in advance. At this time, the elastic plates 467 and 468 of the holding member 460 are assumed to be in a natural state.
　まず、図１８（Ａ１）、図１８（Ａ２）に示すように、上記スライド挿入方向（図６中に矢印Ａ１で示す）に沿って、保持部材４６０が、右側壁１６の内面１６ｉと案内コラム４７１，４７２との間に挿入される。このとき、弾性板４６７，４６８は、それぞれ、右側壁１６の内面１６ｉと平行に、案内コラム４７１，４７２の外へ延在した状態にある。保持部材４６０がストッパ４７５に当接すると、保持部材４６０のスライド挿入は停止する。この状態で、図１８（Ａ１）における保持部材４６０の左右方向の動きは、案内コラム４７１，４７２によって規制される。保持部材４６０の上下方向（右側壁１６の内面１６ｉに対して垂直な方向）の動きは、若干だけ許容される。 First, as shown in FIGS. 18 (A1) and 18 (A2), the holding member 460 is attached to the inner surface 16i of the right side wall 16 and the guide column along the slide insertion direction (indicated by the arrow A1 in FIG. 6). It is inserted between 471 and 472. At this time, the elastic plates 467 and 468 are in a state of extending to the outside of the guide columns 471 and 472 in parallel with the inner surface 16i of the right side wall 16, respectively. When the holding member 460 comes into contact with the stopper 475, the slide insertion of the holding member 460 is stopped. In this state, the movement of the holding member 460 in the left-right direction in FIG. 18A is regulated by the guide columns 471 and 472. The vertical movement of the holding member 460 (the direction perpendicular to the inner surface 16i of the right side wall 16) is slightly allowed.
　次に、図１８（Ｂ１）、図１８（Ｂ２）に示すように、上壁１１が側壁部１３Ｓ（したがって、右側壁１６）に取り付けられる。このとき、図１８（Ｂ２）中に矢印Ｈ１，Ｈ２で示すように、保持部材設置部４７０に上壁１１の押さえリブ４７７，４７８が挿入されて、押さえリブ４７７，４７８の端面４７７ｆ，４７８ｆが弾性板４６７，４６８に当接する。これにより、押さえリブ４７７，４７８から弾性板４６７，４６８が、図１８（Ｂ１）中に示すように、右側壁１６の内面１６ｉへ向けて押圧力Ｆ１１，Ｆ１２を受ける。この結果、保持部材４６０の板部６１の他方の板面６１ｂが右側壁１６の内面１６ｉへ向けて付勢され、押し付けられる。 Next, as shown in FIGS. 18 (B1) and 18 (B2), the upper wall 11 is attached to the side wall portion 13S (hence, the right side wall 16). At this time, as shown by arrows H1 and H2 in FIG. 18B2, the holding ribs 477 and 478 of the upper wall 11 are inserted into the holding member installation portion 470, and the end faces 477f and 478f of the holding ribs 477 and 478 are formed. It abuts on the elastic plates 467 and 468. As a result, the elastic plates 467 and 468 from the pressing ribs 477 and 478 receive the pressing forces F11 and F12 toward the inner surface 16i of the right side wall 16 as shown in FIG. 18 (B1). As a result, the other plate surface 61b of the plate portion 61 of the holding member 460 is urged and pressed toward the inner surface 16i of the right side wall 16.
　このようにして、上壁１１が側壁部１３Ｓ（したがって、右側壁１６）に取り付けられた状態では、一対の案内コラム４７１，４７２が、保持部材４６０の図１８（Ｂ１）、図１８（Ｂ２）における左右方向への動きを規制する。また、上壁１１から延在する押さえリブ４７７，４７８が、弾性板４６７，４６８を介して、保持部材４６０の右側壁１６の内面１６ｉに対して垂直な方向への動き、および、上方（図６中に矢印Ａ２で示した方向）への離脱の動きを規制する。ストッパ４７５が、保持部材４６０の下方（図６中に矢印Ａ１で示した方向）への動きを規制する。また、規制リブ４７６は、保持部材４６０から、圧電ブザー４０が脱落するのを規制する。この状態では、保持部材４６０の板部６１の他方の板面６１ｂが右側壁１６の内面１６ｉへ向けて付勢され、押し付けられる。これにより、右側壁１６の内面１６ｉに設けられた保持部材設置部４７０に、圧電ブザー４０を保持した状態の保持部材４６０が固定される。このようにして、血圧計１の完成状態では、右側壁１６の内面１６ｉに、保持部材４６０が、圧電ブザー４０の振動を右側壁１６に伝達させる態様で固定される。 In this way, when the upper wall 11 is attached to the side wall portion 13S (hence, the right side wall 16), the pair of guide columns 471 and 472 are attached to the holding members 460 in FIGS. 18 (B1) and 18 (B2). To regulate the movement in the left-right direction. Further, the pressing ribs 477,478 extending from the upper wall 11 move in a direction perpendicular to the inner surface 16i of the right side wall 16 of the holding member 460 via the elastic plates 467,468, and upward (FIG. FIG. The movement of withdrawal in the direction indicated by the arrow A2 in 6) is regulated. The stopper 475 regulates the downward movement of the holding member 460 (the direction indicated by the arrow A1 in FIG. 6). Further, the regulation rib 476 regulates the piezoelectric buzzer 40 from falling off from the holding member 460. In this state, the other plate surface 61b of the plate portion 61 of the holding member 460 is urged and pressed toward the inner surface 16i of the right side wall 16. As a result, the holding member 460 in a state of holding the piezoelectric buzzer 40 is fixed to the holding member installation portion 470 provided on the inner surface 16i of the right side wall 16. In this way, in the completed state of the sphygmomanometer 1, the holding member 460 is fixed to the inner surface 16i of the right side wall 16 in such a manner that the vibration of the piezoelectric buzzer 40 is transmitted to the right side wall 16.
　この変形例４の血圧計１では、保持部材４６０の板部６１が右側壁１６の内面１６ｉへ向けて付勢され、押し付けられるので、圧電ブザー４０から右側壁１６の内面１６ｉへの振動の伝達効率が高まって、音波による通信状態をさらに良好に保つことができる。 In the sphygmomanometer 1 of the modified example 4, the plate portion 61 of the holding member 460 is urged and pressed toward the inner surface 16i of the right side wall 16, so that the vibration is transmitted from the piezoelectric buzzer 40 to the inner surface 16i of the right side wall 16. The efficiency is increased, and the communication state by sound waves can be maintained even better.
　この変形例４では、保持部材４６０の弾性板４６７，４６８が略平板状であるものとしたが、これに限られるものではない。例えば、図１７（Ｃ）は、図１７（Ｂ）におけるのと同じ視方向で、弾性板４６７，４６８を変形した弾性板４６７′，４６８′を示している（理解の容易のため、保持部材４６０の他の部分の図示を省略している。）。これらの弾性板４６７′，４６８′は、押さえリブ４７７，４７８の端面４７７ｆ，４７８ｆに対向する傾斜面４６７ｆ′，４６８ｆ′を有している。これにより、上壁１１が側壁部１３Ｓ（したがって、右側壁１６）に取り付けられるとき、図１７（Ｃ）中に矢印Ｄ１で示すように、押さえリブ４７７，４７８の端面４７７ｆ，４７８ｆが、それぞれ弾性板４６７′，４６８′の傾斜面４６７ｆ′，４６８ｆ′に当接する。この結果、押さえリブ４７７，４７８から弾性板４６７′，４６８′が、右側壁１６の内面１６ｉへ向けて、それぞれ矢印Ｄ２で示す向きに安定して適度の押圧力を受ける。この結果、保持部材４６０の板部６１の他方の板面６１ｂが右側壁１６の内面１６ｉへ向けて安定して付勢され、押し付けられる。したがって、圧電ブザー４０から右側壁１６の内面１６ｉへの振動の伝達効率が安定して、音波による通信状態をさらに良好に保つことができる。 In this modification 4, the elastic plates 467 and 468 of the holding member 460 are assumed to have a substantially flat plate shape, but the present invention is not limited to this. For example, FIG. 17 (C) shows elastic plates 467', 468', which are deformed elastic plates 467, 468, in the same viewing direction as in FIG. 17 (B). The illustration of other parts of 460 is omitted.) These elastic plates 467'and 468' have inclined surfaces 467f' and 468f' facing the end faces 477f and 478f of the pressing ribs 477 and 478. As a result, when the upper wall 11 is attached to the side wall portion 13S (hence, the right side wall 16), the end faces 477f and 478f of the pressing ribs 477 and 478 are elastic, respectively, as shown by the arrow D1 in FIG. 17 (C). It abuts on the inclined surfaces 467f', 468f' of the plates 467'and 468'. As a result, the elastic plates 467'and 468' from the pressing ribs 477 and 478 are stably subjected to an appropriate pressing force in the direction indicated by the arrow D2 toward the inner surface 16i of the right side wall 16. As a result, the other plate surface 61b of the plate portion 61 of the holding member 460 is stably urged and pressed toward the inner surface 16i of the right side wall 16. Therefore, the transmission efficiency of vibration from the piezoelectric buzzer 40 to the inner surface 16i of the right side wall 16 is stable, and the communication state by sound waves can be further maintained.
　（変形例５）
　図１９（Ａ）、図１９（Ｂ）は、変形例４の保持部材４６０をさらに変形した別の保持部材５６０を、それぞれ図９（Ａ）、図９（Ｃ）に対応する状態で模式的に示している。 (Modification 5)
19 (A) and 19 (B) schematically show another holding member 560 obtained by further deforming the holding member 460 of the modified example 4 in a state corresponding to FIGS. 9 (A) and 9 (C), respectively. It is shown in.
　図１９（Ａ）、図１９（Ｂ）によって分かるように、この変形例５の保持部材５６０では、変形例４の保持部材４６０の弾性板４６７，４６８に代えて、矩形板部６２，６３の板部６１から遠い側の端面に、それぞれ弾性を示す弾性部としての略平板状の弾性板５６７，５６８が設けられている点が異なっている。図１９（Ｂ）に示すように、弾性板５６８は、矩形板部６３の対応する端面の略中央から斜め下方（図１９（Ｂ）において）へ延在している。簡単のため、詳細（挟持部６５，６６）の図示は省略しているが、変形例５の保持部材５６０の他の構成は、変形例４の保持部材４６０におけるのと同じになっている。 As can be seen from FIGS. 19A and 19B, in the holding member 560 of the modified example 5, instead of the elastic plates 467 and 468 of the holding member 460 of the modified example 4, the rectangular plate portions 62 and 63 are used. The difference is that substantially flat plate-shaped elastic plates 567 and 568 are provided on the end faces on the side far from the plate portion 61, respectively, as elastic portions exhibiting elasticity. As shown in FIG. 19B, the elastic plate 568 extends obliquely downward (in FIG. 19B) from substantially the center of the corresponding end face of the rectangular plate portion 63. Although the details (holding portions 65 and 66) are not shown for the sake of simplicity, the other configurations of the holding member 560 of the modified example 5 are the same as those of the holding member 460 of the modified example 4.
　図１９（Ｃ）中に、図１７（Ｃ）におけるのと同じ視方向で、この変形例５における上壁１１の構成要素としての押さえリブ５７８を示している。この変形例５では、上壁１１は、変形例４における一対の押さえリブ４７７，４７８に代えて、図１９（Ｃ）において紙面に対して垂直な方向（図１７（Ａ）における左右方向に相当）に延在する一体物の押さえリブ５７８を備えている。押さえリブ５７８は、上壁１１の装着時に弾性板５６７，５６８の傾斜面５６７ｆ，５６８ｆと略平行になる向きに傾斜した傾斜面５７８ｆを有している。 In FIG. 19 (C), the holding rib 578 as a component of the upper wall 11 in this modification 5 is shown in the same viewing direction as in FIG. 17 (C). In the modified example 5, the upper wall 11 replaces the pair of pressing ribs 477 and 478 in the modified example 4 in the direction perpendicular to the paper surface in FIG. 19 (C) (corresponding to the left-right direction in FIG. 17 (A)). ) Is provided with an integral holding rib 578 extending to the). The pressing rib 578 has an inclined surface 578f inclined in a direction substantially parallel to the inclined surfaces 567f and 568f of the elastic plates 567 and 568 when the upper wall 11 is mounted.
　この変形例５の保持部材５６０は、圧電ブザー４０を保持した状態で、変形例４の保持部材４６０に関して図１８（Ａ１）、図１８（Ａ２）～図１８（Ｂ１）、図１８（Ｂ２）に示したのと同じ過程で、保持部材設置部４７０に装着される。 The holding member 560 of the modified example 5 holds the piezoelectric buzzer 40, and the holding member 460 of the modified example 4 is shown in FIGS. 18 (A1), 18 (A2) to 18 (B1), and 18 (B2). In the same process as shown in the above, the holding member is attached to the holding member installation portion 470.
　ここで、図１９（Ｃ）に示すように、上壁１１が側壁部１３Ｓ（したがって、右側壁１６）に取り付けられとき、矢印Ｊ１で示すように、保持部材設置部４７０に上壁１１の押さえリブ５７８が挿入されて、図１９（Ｃ）中に矢印Ｊ１で示すように、押さえリブ５７８の傾斜面５７８ｆが弾性板５６７，５６８の傾斜面５６７ｆ，５６８ｆに当接するものとする。この結果、押さえリブ５７８から弾性板５６７，５６８が、右側壁１６の内面１６ｉへ向けて、矢印Ｊ２で示す向きに安定して適度の押圧力を受ける。この結果、保持部材４６０の板部６１の他方の板面６１ｂが右側壁１６の内面１６ｉへ向けて安定して付勢され、押し付けられる。したがって、圧電ブザー４０から右側壁１６の内面１６ｉへの振動の伝達効率が安定して、音波による通信状態をさらに良好に保つことができる。 Here, as shown in FIG. 19C, when the upper wall 11 is attached to the side wall portion 13S (hence, the right side wall 16), as shown by the arrow J1, the holding member installation portion 470 holds the upper wall 11. It is assumed that the rib 578 is inserted and the inclined surface 578f of the pressing rib 578 abuts on the inclined surfaces 567f and 568f of the elastic plates 567 and 568 as shown by an arrow J1 in FIG. 19C. As a result, the elastic plates 567 and 568 are stably subjected to an appropriate pressing force from the pressing rib 578 toward the inner surface 16i of the right side wall 16 in the direction indicated by the arrow J2. As a result, the other plate surface 61b of the plate portion 61 of the holding member 460 is stably urged and pressed toward the inner surface 16i of the right side wall 16. Therefore, the transmission efficiency of vibration from the piezoelectric buzzer 40 to the inner surface 16i of the right side wall 16 is stable, and the communication state by sound waves can be further maintained.

The outer shape of the piezoelectric buzzer 40 may have other shapes such as an elliptical plate shape and a plate shape having a rounded quadrangle (a quadrangle with rounded corners). Further, the vibrating member may be another type of vibrating member as long as it can generate sound waves (including ultrasonic waves).

The present invention can also be applied to an integrated sphygmomanometer in which a blood pressure measuring cuff and a main body are integrated. Further, the present invention can be widely applied to a biometric information measuring device that communicates pulse, body temperature and other biometric information other than blood pressure with an external terminal provided with a microphone via sound waves (including ultrasonic waves).
