Description

本発明は、スイッチ及び電子機器に関する。   The present invention relates to a switch and an electronic device.

従来、外力が加えられることで接点電極のオンとオフとが切り替わるスイッチが知られている。このようなスイッチとして、特許文献１には、固定接点と、固定接点に対して相対移動する可動接点と、外力が加えられることによって可動接点を固定接点に接触させるプッシュボタン（操作入力部材）を備えるスイッチが記載されている。   2. Description of the Related Art Conventionally, a switch that switches on and off of a contact electrode by applying an external force is known. As such a switch, Patent Document 1 discloses a fixed contact, a movable contact that moves relative to the fixed contact, and a push button (operation input member) that brings the movable contact into contact with the fixed contact by applying an external force. A switch to be provided is described.

また、このようなスイッチは、例えば、中央演算装置や主記憶装置などが実装された刀身状のサーバー装置と筐体とを備える電子機器においてサーバー装置と筐体とを着脱する場合に、サーバー装置などを着脱するためのレバーが一体に設けられた押圧部材と連動して操作されてサーバー装置が筐体に接続されたか否かを検出するためのスイッチとして使用されている。   In addition, such a switch is used when, for example, a server device and a housing are attached to and detached from an electronic device including a blade-like server device and a housing on which a central processing unit, a main storage device, and the like are mounted. The server device is used as a switch for detecting whether or not the server device is connected to the housing by being operated in conjunction with a pressing member integrally provided.

しかしながら、従来のスイッチは、操作入力部材の外面に対して繰り返し外力が加わることで操作入力部材が磨耗する場合がある。この場合、スイッチの製造時に設定された位置と異なる位置で接点電極の接触及び離間が起こってしまい、接点電極の動作が不安定になるという問題がある。   However, in the conventional switch, the operation input member may be worn due to repeated external force applied to the outer surface of the operation input member. In this case, there is a problem that the contact electrode contacts and separates at a position different from the position set at the time of manufacturing the switch, and the operation of the contact electrode becomes unstable.

また、従来の電子機器は、スイッチの操作入力部材が磨耗しないように、また操作入力部材に対して適切な方向から外力が加わるように、サーバー装置などのレバーの回動中心から離れた位置にスイッチを配置する必要があった。   In addition, the conventional electronic device is located at a position away from the rotation center of the lever of the server device or the like so that the operation input member of the switch is not worn and an external force is applied to the operation input member from an appropriate direction. It was necessary to place a switch.

本発明は、上述した事情に鑑みてなされたものであって、その目的は、操作入力部材に対して繰り返し外力が加えられても安定して接点部を操作することができるスイッチを提供し、また、操作入力部材に外力が加わる方向が適切な方向からずれてもスイッチを好適に操作できる電子機器を提供することである。   The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a switch that can stably operate a contact portion even when an external force is repeatedly applied to an operation input member. It is another object of the present invention to provide an electronic device that can operate the switch suitably even when the direction in which the external force is applied to the operation input member deviates from an appropriate direction.

本発明のスイッチは、内部に接点部を有するスイッチ本体と、前記スイッチ本体から突出して設けられ、外力を伝達して前記接点部の接離を操作するための操作入力部材とを備えるスイッチであって、前記操作入力部材において前記外力を受ける端部には、転動体が転動自在に支持されていることを特徴とする。   The switch according to the present invention is a switch including a switch body having a contact portion therein and an operation input member that is provided so as to protrude from the switch body and that transmits and receives an external force to operate the contact portion. A rolling element is supported on the end of the operation input member that receives the external force so as to roll freely.

本発明の電子機器は、内部に空洞を有する収容体と前記収容体に収容される被収容体とが互いに着脱可能に設けられた電子機器であって、前記被収容体は、請求項１から請求項３のいずれか一項に記載のスイッチと、前記スイッチの前記転動体に接触し、前記転動体を介して前記操作入力部材に外力を加えるカム面を有する押圧部材と、前記収容体の内側から外側に向かって前記収容体の内壁面に当接するように前記押圧部材に形成された着脱部と、を備えることを特徴とする。   The electronic device of the present invention is an electronic device in which a housing body having a cavity therein and a body to be housed accommodated in the housing body are detachably provided. A switch according to any one of claims 3 to 7, a pressing member having a cam surface that contacts the rolling element of the switch and applies an external force to the operation input member via the rolling element; An attaching / detaching portion formed on the pressing member so as to contact the inner wall surface of the container from the inside to the outside.

本発明のスイッチによれば、操作入力部材に設けられた転動体が転動することで操作入力部材と被接触体との間の摩擦抵抗が低減されているので、操作入力部材が磨耗するのを抑えることができる。このため、操作入力部材に対して繰り返し外力が加えられても安定して接点部を操作することができる。
また、本発明の電子機器によれば、操作入力部材に転動体が設けられているので、操作入力部材に外力が加わる方向が適切な方向からずれてもスイッチを好適に操作できる。 According to the switch of the present invention, since the rolling element provided on the operation input member rolls, the frictional resistance between the operation input member and the contacted body is reduced, so the operation input member is worn. Can be suppressed. For this reason, even if an external force is repeatedly applied to the operation input member, the contact portion can be stably operated.
Further, according to the electronic device of the present invention, since the rolling element is provided on the operation input member, the switch can be suitably operated even if the direction in which the external force is applied to the operation input member is deviated from an appropriate direction.

（第１実施形態）
以下、本発明の第１実施形態のスイッチについて説明する。図１は、本実施形態のスイッチ１を示す図で、（Ａ）は正面図、（Ｂ）は平面図、（Ｃ）は右側面図である。図２（Ａ）ないし図２（Ｃ）は、スイッチ１の使用時の動作を示す動作説明図である。 (First embodiment)
The switch according to the first embodiment of the present invention will be described below. 1A and 1B are diagrams showing a switch 1 according to this embodiment, in which FIG. 1A is a front view, FIG. 1B is a plan view, and FIG. 1C is a right side view. FIG. 2A to FIG. 2C are operation explanatory diagrams showing the operation when the switch 1 is used.

図１に示すように、スイッチ１は、図示しない接点電極を内部に有するスイッチ本体１０と、スイッチ本体１０から突出して設けられた操作入力部材２０と、操作入力部材２０の端部２０Ａに設けられた転動体３０とを備えている。   As shown in FIG. 1, the switch 1 is provided at a switch body 10 having a contact electrode (not shown) therein, an operation input member 20 provided so as to protrude from the switch body 10, and an end 20 </ b> A of the operation input member 20. The rolling element 30 is provided.

スイッチ本体１０は、端子１２Ａ、１２Ｂ、１２Ｃ、１２Ｄが、ケース１１の内部で接点電極に導通するようにケース１１の外面に設けられている。   The switch body 10 is provided on the outer surface of the case 11 so that the terminals 12A, 12B, 12C, and 12D are electrically connected to the contact electrodes inside the case 11.

操作入力部材２０は、例えば棒状に形成されており、ケース１１から突き出した端部２０Ａには、転動体３０を支持する受座２１が設けられている。操作入力部材２０は、ケース１１に対して操作入力部材２０の軸方向に進退動作してケース１１の内部の図示しない接点部を操作するようになっている。   The operation input member 20 is formed in a rod shape, for example, and a receiving seat 21 that supports the rolling element 30 is provided at an end 20A protruding from the case 11. The operation input member 20 moves back and forth in the axial direction of the operation input member 20 with respect to the case 11 to operate a contact portion (not shown) inside the case 11.

本実施形態では、受座２１は、球面の一部をなすような曲面形状を有している。また、受座２１における端部２０Ａ側の一部には、操作入力部材２０の径方向内側に向かって延びるストッパ部２２が設けられている。ストッパ部２２は、転動体３０が受座２１から脱落しないように、かつ転動体３０を転動自在に支持するものである。   In the present embodiment, the receiving seat 21 has a curved surface shape that forms a part of a spherical surface. Further, a stopper portion 22 that extends toward the inside in the radial direction of the operation input member 20 is provided on a part of the receiving seat 21 on the end 20 </ b> A side. The stopper portion 22 supports the rolling element 30 so that the rolling element 30 does not fall off the seat 21 and can roll.

転動体３０は、例えばステンレス鋼などからなる球体で、受座２１において自在に転動するように受座２１に支持されている。また、転動体３０と受座２１との間は、転動体３０が受座２１で自在に転動できる程度に摩擦抵抗が低減された低摩擦部になっている。具体的には、受座２１には、転動体３０に点接触する突起が形成されている。また、受座２１において転動体３０に接触する部分がフッ素樹脂などの樹脂材料で構成されていてもよい。   The rolling element 30 is a spherical body made of, for example, stainless steel and is supported by the receiving seat 21 so as to roll freely in the receiving seat 21. Further, a space between the rolling element 30 and the seat 21 is a low friction part with reduced frictional resistance to such an extent that the rolling element 30 can freely roll on the seat 21. Specifically, a protrusion that makes point contact with the rolling element 30 is formed on the seat 21. Moreover, the part which contacts the rolling element 30 in the seat 21 may be comprised with resin materials, such as a fluororesin.

本実施形態では、ケース１１に対して操作入力部材２０が最大に突出している状態と、ケース１１に対して操作入力部材２０が最大に押し込まれている状態とが切り替わることで、端子１２Ａ、１２Ｂ、１２Ｃ、１２Ｄの間の導通状態が第一状態と第二状態との間で相互に切り替わるようになっている。第一状態と第二状態とのそれぞれにおける端子１２Ａ、１２Ｂ、１２Ｃ、１２Ｄの接離は適宜に設定して構成することができる。一例を挙げると、第一状態では端子１２Ａ、１２Ｂ、１２Ｃ、１２Ｄが互いに導通していない状態であり、第二状態では端子１２Ａと端子１２Ｂとが導通するとともに端子１２Ｃと端子１２Ｄとが導通するようになっている。   In the present embodiment, the terminals 12A and 12B are switched by switching between a state in which the operation input member 20 protrudes to the maximum with respect to the case 11 and a state in which the operation input member 20 is pressed to the maximum with respect to the case 11. , 12C, 12D are switched between the first state and the second state. The contact and separation of the terminals 12A, 12B, 12C, and 12D in each of the first state and the second state can be appropriately set and configured. For example, in the first state, the terminals 12A, 12B, 12C, and 12D are not connected to each other. In the second state, the terminals 12A and 12B are connected and the terminals 12C and 12D are connected. It is like that.

以上に説明した構成の、本実施形態のスイッチ１の使用時の動作について説明する。
図２（Ａ）に示すように、スイッチ１は、被接触体１００に対して転動体３０の外面が接触するように配置されて使用される。スイッチ１と被接触体１００との位置関係は、スイッチ１の操作入力部材２０の端部２０Ａに設けられた転動体３０が平坦面１０（例えば点Ｘ）に接する位置関係にあるときは、操作入力部材２０がケース１１から最大に突出する位置関係になっている。このとき、スイッチ１の端子１２Ａ、１２Ｂ、１２Ｃ、１２Ｄの導通状態は上述の第一状態になっている。 An operation when the switch 1 of the present embodiment having the configuration described above is used will be described.
As shown in FIG. 2A, the switch 1 is arranged and used so that the outer surface of the rolling element 30 contacts the contacted body 100. When the rolling element 30 provided at the end 20A of the operation input member 20 of the switch 1 is in contact with the flat surface 10 (for example, point X), the positional relationship between the switch 1 and the contacted object 100 is The input member 20 is positioned so as to protrude from the case 11 to the maximum. At this time, the conduction state of the terminals 12A, 12B, 12C, and 12D of the switch 1 is the first state described above.

図２（Ｂ）に示すＡ方向に被接触体１００が相対移動すると、操作入力部材２０は転動体３０とともにケース１１の内部方向へ移動する。カム面１０２から転動体３０に加わる外力は、操作入力部材２０の軸方向に対して角度を有しており、転動体３０が受ける外力は、操作入力部材２０の軸方向の成分と操作入力部材２０の軸に直交する方向の成分とを有している。操作入力部材２０の軸に直交する外力の成分によって、転動体３０は転動する。このとき、転動体３０の外面とカム面１０２との間に発生する摩擦は転がり摩擦であり、転動体３０の外面とカム面１０２との間の転がり摩擦係数は転動体３０の外面とカム面１０２との間のすべり摩擦係数より小さい。   When the contacted body 100 relatively moves in the A direction shown in FIG. 2B, the operation input member 20 moves in the inner direction of the case 11 together with the rolling elements 30. The external force applied to the rolling element 30 from the cam surface 102 has an angle with respect to the axial direction of the operation input member 20, and the external force received by the rolling element 30 includes the axial component of the operation input member 20 and the operation input member. And a component in a direction perpendicular to the 20 axes. The rolling element 30 rolls due to an external force component orthogonal to the axis of the operation input member 20. At this time, the friction generated between the outer surface of the rolling element 30 and the cam surface 102 is rolling friction, and the rolling friction coefficient between the outer surface of the rolling element 30 and the cam surface 102 is the outer surface of the rolling element 30 and the cam surface. The sliding friction coefficient with respect to 102 is smaller.

スイッチ１と被接触体１００とが図２（Ｃ）に示すようにカム面１０２の頂点Ｙに転動体３０が位置する位置関係にあるときは、操作入力部材２０がケース１１に対して最大に押し込まれた位置関係になっており、転動体３０がカム面１０２に沿って動作することで上述の第一状態から第二状態へ切り替わる。   When the switch 1 and the contacted body 100 are in a positional relationship in which the rolling element 30 is positioned at the vertex Y of the cam surface 102 as shown in FIG. The positional relationship has been pushed in, and the rolling element 30 moves along the cam surface 102 to switch from the first state to the second state.

被接触体１００が図２（Ｂ）に示すＡ方向と反対方向に移動したときには、転動体３０は転動しつつ、操作入力部材２０はケース１１から外向きに移動する。平坦面１０１の点Ｘに転動体３０が到達したときには、スイッチ本体１０においては上述の第二状態から第一状態へ切り替わっている。   When the contacted body 100 moves in the direction opposite to the direction A shown in FIG. 2B, the operation input member 20 moves outward from the case 11 while the rolling element 30 rolls. When the rolling element 30 reaches the point X on the flat surface 101, the switch body 10 is switched from the second state to the first state.

以上説明したように、本実施形態のスイッチ１によれば、操作入力部材２０に設けられた転動体３０によってカム面１０２との間の摩擦力が低減されている。そのため、操作入力部材２０が磨耗することが軽減され、操作入力部材の動作方向と異なる方向から外力が操作入力部材に対して繰り返して加えられても安定して接点電極を動作させることができる。   As described above, according to the switch 1 of the present embodiment, the frictional force with the cam surface 102 is reduced by the rolling elements 30 provided on the operation input member 20. Therefore, the wear of the operation input member 20 is reduced, and the contact electrode can be stably operated even when an external force is repeatedly applied to the operation input member from a direction different from the operation direction of the operation input member.

（第２実施形態）
次に、本発明の第２実施形態の電子機器について図４及び図５を参照して説明する。なお、本実施形態において、上述した第１実施形態のスイッチ１と構成を共通とする箇所には同一符号を付けて、説明を省略することにする。
図３（Ａ）は、本実施形態の電子機器２の一部の構成を示す部分断面図である。また、図３（Ｂ）は、電子機器２の使用時の動作を示す動作説明図である。 (Second Embodiment)
Next, an electronic apparatus according to a second embodiment of the present invention will be described with reference to FIGS. In the present embodiment, portions having the same configuration as those of the switch 1 of the first embodiment described above are denoted by the same reference numerals and description thereof is omitted.
FIG. 3A is a partial cross-sectional view illustrating a partial configuration of the electronic apparatus 2 of the present embodiment. FIG. 3B is an operation explanatory diagram showing an operation when the electronic device 2 is used.

図３（Ａ）に示すように、本実施形態の電子機器２は、例えばAdvanced TCA（Telecom Computing Architecture）にハードウエア仕様が定められた外枠となる収容体３０１と、収容体３０１の内部に収容される被収容体３００との間に介在されて設けられている。   As shown in FIG. 3A, the electronic device 2 according to the present embodiment includes, for example, a housing 301 that is an outer frame whose hardware specifications are defined in Advanced TCA (Telecom Computing Architecture), and a housing 301. It is interposed between the object 300 to be accommodated.

収容体３００は、上述の第１実施形態で説明したスイッチ１が回路基板３１０上に実装され、回路基板３１０には、収容体３００に固定された回動軸部材２０３を介して連結された押圧部材２００と、押圧部材２００の外面の一部に引っ掛けて押圧部材２００の位置を固定する固定部３２０と、が取り付けられている。   In the container 300, the switch 1 described in the first embodiment is mounted on the circuit board 310, and the circuit board 310 is connected to the press through the rotation shaft member 203 fixed to the container 300. A member 200 and a fixing portion 320 that is hooked on a part of the outer surface of the pressing member 200 and fixes the position of the pressing member 200 are attached.

回動軸部材２０３は、回路基板３１０の面に垂直な方向に延びる円柱形状で、押圧部材２００は回路基板３１０が存する面と平行な面に沿って回動軸部材２０３回りに回動するようになっている。本実施形態では、回動軸部材２０３とスイッチ１との位置関係は、スイッチ１のケース１１から突出する操作入力部材２０が、回動軸部材２０３の回動中心軸に向かって延びる位置関係になっている。   The rotation shaft member 203 has a cylindrical shape extending in a direction perpendicular to the surface of the circuit board 310, and the pressing member 200 rotates about the rotation shaft member 203 along a plane parallel to the surface on which the circuit board 310 exists. It has become. In the present embodiment, the positional relationship between the rotation shaft member 203 and the switch 1 is such that the operation input member 20 protruding from the case 11 of the switch 1 extends toward the rotation center axis of the rotation shaft member 203. It has become.

押圧部材２００は、回動軸部材２０３回りに相対回動自在で回動軸部材２０３回りに延びて形成されたカム面２０１、２０２と、被収容体３００が収容体３０１に収容されている状態で収容体３０１の外部側に延びて設けられたレバー部２１０と、被収容体３００の内部側に突出してレバー部２１０の一部に設けられたフック部２２０と、を備えている。   The pressing member 200 is a state in which the cam surfaces 201 and 202 formed so as to be relatively rotatable around the rotation shaft member 203 and extending around the rotation shaft member 203, and the container 300 are accommodated in the container 301. The lever part 210 is provided to extend to the outside of the container 301 and the hook part 220 is provided on a part of the lever part 210 so as to protrude to the inside of the container 300.

カム面２０１とカム面２０２とは、回動軸部材２０３の回動中心軸からの距離が異なっており、カム面２０２と回動中心軸との間の距離は、カム面２０１と回動中心軸との間の距離よりも長くなっている。カム面２０１とカム面２０２との間の傾斜カム面２０４は、カム面２０１からカム面２０２に向かうに従って回動軸部材２０３の回動中心軸との間の距離が漸次長くなるように形成されている。   The cam surface 201 and the cam surface 202 have different distances from the rotation center axis of the rotation shaft member 203, and the distance between the cam surface 202 and the rotation center axis is the same as the cam surface 201 and the rotation center. It is longer than the distance between the shafts. The inclined cam surface 204 between the cam surface 201 and the cam surface 202 is formed such that the distance from the rotation center axis of the rotation shaft member 203 is gradually increased from the cam surface 201 toward the cam surface 202. ing.

本実施形態では、カム面２０１とカム面２０２とのそれぞれには、スイッチ１の操作入力部材２０に設けられた転動体３０の外面が接触するようになっており、操作入力部材２０がケース１１の外向きに付勢される付勢力によってカム面２０１、カム面２０２及び傾斜カム面２０４に転動体３０は押圧されている。
本実施形態の電子機器２において、スイッチ１は被収容体３００に対して収容体３０１が収容されたことを検知するスイッチである。 In this embodiment, the outer surface of the rolling element 30 provided on the operation input member 20 of the switch 1 is in contact with each of the cam surface 201 and the cam surface 202, and the operation input member 20 is in the case 11. The rolling element 30 is pressed against the cam surface 201, the cam surface 202, and the inclined cam surface 204 by the outward urging force.
In the electronic device 2 of the present embodiment, the switch 1 is a switch that detects that the container 301 is accommodated in the object 300.

以上に説明した構成の本実施形態の電子機器２の使用時の動作について説明する。
まず、被収容体３００を収容体３０１の内部に例えば使用者の手作業によって挿入する。すると、レバー部２１０と係止部２３０との間に収容体３０１の一部が挟まれるように、押圧部材２００は収容体３０１に挿入される。 An operation at the time of using the electronic apparatus 2 of the present embodiment having the configuration described above will be described.
First, the container 300 is inserted into the container 301 by a user's manual work, for example. Then, the pressing member 200 is inserted into the container 301 so that a part of the container 301 is sandwiched between the lever part 210 and the locking part 230.

次に、レバー部２１０が被収容体３００に近づく方向に、押圧部材２００を回動軸部材２０３回りに回動させる。すると、係止部２３０は収容体３０１の内壁面３０１Ａに回り込むように回動軸部材２０３を中心に回動し、着脱部Ｚ１において係止部２３０は内壁面３０１Ａを押圧する。これにより、被収容体３００は収容体３０１の内部にさらに押し込まれて、図示しないコネクタなどを介して被収容体３０１と収容体３００とは電気的に接続される。さらにこのとき、回動軸部材２０３回りにカム面２０１、２０２が回動して、転動体３０とカム面２０１、２０２とは、転動体３０が点Ｙに位置する位置関係になる。   Next, the pressing member 200 is rotated around the rotation shaft member 203 in the direction in which the lever portion 210 approaches the object to be accommodated 300. Then, the locking portion 230 rotates around the rotation shaft member 203 so as to wrap around the inner wall surface 301A of the container 301, and the locking portion 230 presses the inner wall surface 301A at the detachable portion Z1. Thereby, the to-be-contained body 300 is pushed further into the inside of the containing body 301, and the to-be-contained body 301 and the containing body 300 are electrically connected through the connector etc. which are not shown in figure. Further, at this time, the cam surfaces 201 and 202 rotate around the rotation shaft member 203 so that the rolling element 30 and the cam surfaces 201 and 202 are in a positional relationship where the rolling element 30 is located at the point Y.

カム面２０１、２０２からは、操作入力部材２０の軸に対して角度を有する方向から転動体３０を介して外力が加えられ、転動体３０がない場合には操作入力部材２０とカム面２０１、２０２とが摺動することで操作入力部材２０の軸が曲がる方向に外力を受けている。しかしながら、操作入力部材２０の軸に直交する外力の成分によって転動体３０が転動することで操作入力部材２０とカム面２０１、２０２との間の摩擦が低減されているため、操作入力部材２０は曲がることなくケース１１の内部側に直線動作する。   From the cam surfaces 201 and 202, an external force is applied via the rolling element 30 from a direction having an angle with respect to the axis of the operation input member 20, and when there is no rolling element 30, the operation input member 20 and the cam surface 201, The external input is received in the direction in which the shaft of the operation input member 20 is bent. However, the friction between the operation input member 20 and the cam surfaces 201 and 202 is reduced by the rolling element 30 rolling by an external force component orthogonal to the axis of the operation input member 20, and therefore the operation input member 20. Moves linearly inside the case 11 without bending.

押圧部材２００とスイッチ１との間では、カム面２０１からカム面２０２へ転動体３０が移動し、操作入力部材２０はケース１１の内向きに移動する。カム面２０１、２０２上の点Ｘから点Ｙへスイッチ１の転動体３０が相対移動すると、スイッチ１においては、端子１２Ａ、１２Ｂ、１２Ｃ、１２Ｄの導通状態が第一状態から第二状態に切り替わる。
このようにして、スイッチ１は、被収容体３００が収容体３０１に確実に装着されたことを検知する。 Between the pressing member 200 and the switch 1, the rolling element 30 moves from the cam surface 201 to the cam surface 202, and the operation input member 20 moves inward of the case 11. When the rolling element 30 of the switch 1 is relatively moved from the point X on the cam surfaces 201 and 202 to the point Y, in the switch 1, the conduction state of the terminals 12A, 12B, 12C, and 12D is switched from the first state to the second state. .
In this way, the switch 1 detects that the container 300 is securely attached to the container 301.

図３（Ｂ）に示すように、レバー部２１０を被収容体３００に近接する方向へ回動軸部材２０３回りに回動させた状態では、レバー部２１０は被収容体３００の外面に沿い、被収容体３００の外面と収容体３０１の外面とは略同一面上に存する位置関係になる。固定部３２０の凸部３２１と係合部２２０の凹部２２１とが係合することで、レバー部２１０は固定部３２０に固定されて、収容体３０１に加わる振動などで押圧部材２００が固定部３２０から外れないようになっている。
これで、被収容体３００の収容体３０１への装着動作は終了する。 As shown in FIG. 3B, in a state where the lever portion 210 is rotated around the rotation shaft member 203 in a direction close to the object to be accommodated 300, the lever portion 210 is along the outer surface of the object to be accommodated 300. The outer surface of the to-be-contained body 300 and the outer surface of the container 301 are in a positional relationship that exists on substantially the same plane. By engaging the convex portion 321 of the fixing portion 320 with the concave portion 221 of the engaging portion 220, the lever portion 210 is fixed to the fixing portion 320, and the pressing member 200 is fixed to the fixing portion 320 by vibration applied to the container 301. It is designed not to come off.
Thus, the mounting operation of the container 300 to the container 301 is completed.

被収容体３００を収容体３０１から取り出すときには、レバー部２１０を被収容体３００の外側方向に引き出すように押圧部材２００を回動軸部材２０３回りに回動させる。すると、レバー部２１０側の着脱部Ｚ２は収容体３０１の外面に当接する。さらに、収容体３０１の外面を支点としてレバー部２１０をさらに収容体３０１の外側に向かって回動させると、被収容体３００を収容体３０１から引き抜く方向に被収容体３００と収容体３０１とが相対移動する。   When the container 300 is taken out from the container 301, the pressing member 200 is rotated around the rotation shaft member 203 so that the lever part 210 is pulled out to the outside of the container 300. Then, the attaching / detaching part Z <b> 2 on the lever part 210 side comes into contact with the outer surface of the container 301. Further, when the lever portion 210 is further rotated toward the outside of the container 301 with the outer surface of the container 301 as a fulcrum, the container 300 and the container 301 are moved in the direction in which the container 300 is pulled out from the container 301. Move relative.

このとき、押圧部材２００とスイッチ１との間では、カム面２０２からカム面２０１に転動体３０が移動し、操作入力部材２０はケース１１の外向きに移動する。これにより、スイッチ１においては、端子１２Ａ、１２Ｂ、１２Ｃ、１２Ｄの導通状態が第二状態から第一状態に切り替わる。
このとき、スイッチ１は、被収容体３００が収容体３０１から取り外されたことを検知する。 At this time, between the pressing member 200 and the switch 1, the rolling element 30 moves from the cam surface 202 to the cam surface 201, and the operation input member 20 moves outward of the case 11. Thereby, in switch 1, the conduction | electrical_connection state of terminal 12A, 12B, 12C, 12D switches from a 2nd state to a 1st state.
At this time, the switch 1 detects that the container 300 has been removed from the container 301.

以上に説明したように、本実施形態の電子機器によれば、点Ｘから点Ｙに転動体３０を移動させる場合には、カム面２０１とカム面２０２とによって、回動軸部材２０３回りの回動方向に押圧力が加わる。このとき、転動体３０がカム面２０１、２０２に接触して転動することでカム面２０１とカム面２０２との間の摩擦抵抗が低減されているので、操作入力部材２０は曲がることなくケース１１の内向きに移動する。このため、スイッチ１を回動軸部材２０３の近傍に配置してもスイッチ１を好適に動作させることができる。   As described above, according to the electronic apparatus of the present embodiment, when the rolling element 30 is moved from the point X to the point Y, the cam surface 201 and the cam surface 202 are used to move around the rotation shaft member 203. A pressing force is applied in the rotation direction. At this time, since the rolling element 30 comes into contact with the cam surfaces 201 and 202 and rolls, the frictional resistance between the cam surface 201 and the cam surface 202 is reduced, so the operation input member 20 is not bent. 11 moves inward. For this reason, even if the switch 1 is disposed in the vicinity of the rotating shaft member 203, the switch 1 can be operated appropriately.

また、従来、押圧部材とスイッチ１との間の位置ずれを少なくするために押圧部材の加工精度を高めて押圧部材を製造していたが、押圧部材の製造するためのコストが高いという問題があった。本実施形態の電子機器によれば、スイッチ１を回動軸部材２０３の近傍に配置することができるので、回動軸部材２０３から離れた位置でスイッチ１の操作入力部材２０を操作する従来の場合に比べて押圧部材２００とスイッチ１との位置ずれが少ない。このため、例えば従来はレーザー加工を要していた押圧部材をＮＣＴ加工（ＮＣタレットパンチ加工）などの加工方法で製造することができ、押圧部材２００を安価に製造することができる。   Conventionally, in order to reduce the positional deviation between the pressing member and the switch 1, the pressing member is manufactured by increasing the processing accuracy of the pressing member. However, there is a problem that the cost for manufacturing the pressing member is high. there were. According to the electronic apparatus of the present embodiment, since the switch 1 can be disposed in the vicinity of the rotating shaft member 203, the conventional operation input member 20 of the switch 1 is operated at a position away from the rotating shaft member 203. Compared to the case, the displacement between the pressing member 200 and the switch 1 is small. For this reason, for example, a pressing member that conventionally required laser processing can be manufactured by a processing method such as NCT processing (NC turret punch processing), and the pressing member 200 can be manufactured at low cost.

以上、本発明の実施形態について図面を参照して詳述したが、具体的な構成はこの実施形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等も含まれる。

For example, in each of the above-described embodiments, the example in which the rolling element is a metal sphere has been described. However, the material of the rolling element is not limited to metal, and the shape of the rolling element is not limited to a sphere. .

Moreover, as a shape of a rolling element, it is good also as a cylindrical shape or a column shape which can roll around a bus-line, for example.

また、上述の各実施形態において、転動体３０と操作入力部材２０に設けられた受座２１との間に、転動体３０と受座２１との間の摩擦抵抗を低減する低摩擦部として別の部材を介在させても良い。例えば転動体３０が鋼球である場合には、低摩擦部の材質としては硬鋼、銅、ガラス、ルビーなどを採用することができる。   Moreover, in each above-mentioned embodiment, it separates as a low friction part which reduces the frictional resistance between the rolling element 30 and the receiving seat 21 between the rolling element 30 and the receiving seat 21 provided in the operation input member 20. These members may be interposed. For example, when the rolling element 30 is a steel ball, hard steel, copper, glass, ruby, or the like can be used as the material of the low friction part.
