And a detection unit 25 that detects the presence or absence of the contents 92 in the storage unit 91 of the blister pack 9.

検知部は、ブリスターパック９の収容部９１が収容される内壁面２２０を有する収容部材２２と、光を射出する光源２３と、光を受光すると共に受光強度に応じた強度の電気信号を出力する受光部２４と、を備える。   The detection unit includes a housing member 22 having an inner wall surface 220 in which the housing unit 91 of the blister pack 9 is housed, a light source 23 that emits light, and an electric signal that receives light and has an intensity corresponding to the received light intensity. A light receiving unit 24.

具体的に、内容物検知装置１は、厚板状の装置本体２と、装置本体２の一方の面を覆うことができるカバー（押圧部）３と、を備える。   Specifically, the content detection device 1 includes a thick plate-like device body 2 and a cover (pressing portion) 3 that can cover one surface of the device body 2.

装置本体２は、筐体２１と、内壁面２２０を有する収容部材２２と、光源２３と、受光部２４と、検出部２５と、を有する。収容部材２２は、複数の内壁面２２０を有する。複数の内壁面２２０のそれぞれは、ブリスターパック９の複数の収容部９１と対応する位置に配置されている。   The apparatus main body 2 includes a housing 21, a housing member 22 having an inner wall surface 220, a light source 23, a light receiving unit 24, and a detection unit 25. The housing member 22 has a plurality of inner wall surfaces 220. Each of the plurality of inner wall surfaces 220 is disposed at a position corresponding to the plurality of accommodating portions 91 of the blister pack 9.

収容部材２２は、矩形の板状であり、かつ厚さ方向に貫通する複数（ブリスターパック９の収容部９１の数に対応した数）の貫通孔を有する部材本体２６と、貫通孔の一方の開口を塞ぐ基板２７と、を有する。本実施形態の収容部材２２では、貫通孔の周面部２６２と、基板２７における貫通孔の一方の開口を塞ぐ部位（閉塞部）２７１と、によって内壁面２２０が構成されている（図２参照）。即ち、複数の内壁面２２０のそれぞれは、周面部２６２と閉塞部２７１とを有する。本実施形態の内壁面２２０は、開口を有すると共に、ブリスターパック９の収容部９１が開口から挿入される。   The accommodating member 22 has a rectangular plate shape and has a plurality of through holes (a number corresponding to the number of the accommodating portions 91 of the blister pack 9) penetrating in the thickness direction, and one of the through holes. And a substrate 27 that closes the opening. In the housing member 22 of the present embodiment, an inner wall surface 220 is configured by the peripheral surface portion 262 of the through hole and a portion (blocking portion) 271 that closes one opening of the through hole in the substrate 27 (see FIG. 2). . That is, each of the plurality of inner wall surfaces 220 includes a peripheral surface portion 262 and a closing portion 271. The inner wall surface 220 of the present embodiment has an opening, and the accommodating portion 91 of the blister pack 9 is inserted from the opening.

また、基板２７に、光源２３と、受光部２４が周面部２６２の径方向に対向する位置にそれぞれ設けられている。   In addition, the light source 23 and the light receiving unit 24 are provided on the substrate 27 at positions facing the circumferential surface portion 262 in the radial direction.

光源２３は、光（赤外領域から紫外領域までの波長のうちの所定の波長の光）を射出する。この光源２３は、単波長の光を射出する。このように、射出される光の波長域を狭くすることで、受光部２４で受光したときの外乱光の影響を除去し易くなる。本実施形態の光源２３は、赤外領域の波長の光を射出する。本実施形態の光源２３は、ＬＥＤである。   The light source 23 emits light (light having a predetermined wavelength among wavelengths from the infrared region to the ultraviolet region). The light source 23 emits single wavelength light. Thus, by narrowing the wavelength range of the emitted light, it becomes easy to remove the influence of disturbance light when the light receiving unit 24 receives light. The light source 23 of the present embodiment emits light having a wavelength in the infrared region. The light source 23 of this embodiment is an LED.

受光部２４は、いわゆる受光素子であり、受光面で受光した光の強度に応じた強度の電気信号を出力する。本実施形態の受光部２４は、光源２３から射出された光を受光する。この受光部２４は、周面部２６２における光源２３と対向する位置に配置されている。   The light receiving unit 24 is a so-called light receiving element, and outputs an electrical signal having an intensity corresponding to the intensity of light received by the light receiving surface. The light receiving unit 24 of the present embodiment receives light emitted from the light source 23. The light receiving unit 24 is disposed at a position facing the light source 23 on the peripheral surface portion 262.

検出部２５は、基板２７に実装されている。この検出部２５は、受光部２４から受信した電気信号の強度が所定の閾値を超えるか否かでブリスターパック９の収容部９１内の内容物９２の有無を検出する。本実施形態の検出部２５は、一つの内壁面２２０と、この内壁面２２０に対応する光源２３および受光部２４とを一つの検知ユニットとしたときに、複数の検知ユニットのそれぞれから電気信号を受信すると共に、検知ユニット毎の収容部９１内の内容物９２の有無を検出する。   The detection unit 25 is mounted on the substrate 27. The detection unit 25 detects the presence or absence of the contents 92 in the storage unit 91 of the blister pack 9 based on whether or not the intensity of the electrical signal received from the light receiving unit 24 exceeds a predetermined threshold value. The detection unit 25 of the present embodiment receives an electrical signal from each of the plurality of detection units when one inner wall surface 220 and the light source 23 and the light receiving unit 24 corresponding to the inner wall surface 220 are one detection unit. While receiving, the presence or absence of the content 92 in the accommodating part 91 for every detection unit is detected.

検出部２５は、検出結果を、スマートフォン等の外部機器に向けて電波により出力する。このスマートフォン等に所定の服薬管理用のソフトをインストールしておくことで、検出結果を受信したスマートフォンで、服薬管理を行うことができる。即ち、ブリスターパック９の複数の収容部９１のうちのいずれの収容部９１内の内容物９２が無いかが検出できるため、例えば、毎日所定個数の錠剤を服薬したか否かや、所定時間ごとに錠剤を服薬したか否か等の管理を行うことができる。   The detection unit 25 outputs the detection result by radio waves toward an external device such as a smartphone. By installing predetermined medication management software on the smartphone or the like, medication management can be performed with the smartphone that has received the detection result. That is, since it is possible to detect which of the plurality of storage portions 91 of the blister pack 9 is free of the contents 92, for example, whether or not a predetermined number of tablets have been taken every day, every predetermined time It is possible to manage whether or not a tablet has been taken.

なお、内容物検知装置１からの出力情報を受信する前記の外部機器は、スマートフォンに限定されず、ＰＤＡ等の携帯端末、ＰＣ、服薬管理専用端末等でもよい。また、外部機器は、内容物検知装置１の使用場所から離れた場所に設置されてＬＡＮやインターネット等を経由して接続されるサーバ等であってもよい。即ち、外部機器は、収容部９１毎の内容物９２の有無についての情報を利用する機器であればよい。また、本実施形態の内容物検知装置１は、無線接続によって、外部機器に収容部９１毎の内容物９２の有無についての情報を出力しているが、有線接続によって、外部機器に収容部９１毎の内容物９２の有無についての情報を出力する構成でもよい。   In addition, the said external apparatus which receives the output information from the content detection apparatus 1 is not limited to a smart phone, A portable terminal, such as PDA, PC, a terminal for exclusive use of medication management, etc. may be sufficient. The external device may be a server or the like that is installed at a location away from the location where the content detection device 1 is used and connected via a LAN, the Internet, or the like. That is, the external device may be a device that uses information about the presence / absence of the contents 92 for each storage unit 91. Moreover, although the content detection apparatus 1 of this embodiment is outputting the information about the presence or absence of the content 92 for every accommodating part 91 to an external apparatus by wireless connection, the accommodating part 91 is transmitted to an external apparatus by wired connection. The configuration may be such that information about the presence or absence of the contents 92 for each is output.

カバー３は、板状の部材であり、矩形板状の装置本体２の長辺に、該長辺に沿った軸を回動軸として回動可能に取り付けられている。本実施形態のカバー３は、閉じた状態のときに、ブリスターパック９を収容部材２２に向けて押さえる機能を有する。   The cover 3 is a plate-like member, and is attached to the long side of the rectangular plate-like device main body 2 so as to be rotatable about an axis extending along the long side. The cover 3 of the present embodiment has a function of pressing the blister pack 9 toward the housing member 22 when the cover 3 is closed.

以上のように構成される内容物検知装置１は、以下のように使用される。   The content detection apparatus 1 configured as described above is used as follows.

カバー３が開かれ（図２参照）、各収容部９１が収容されるようにブリスターパック９が収容部材２２上に配置される。ブリスターパック９が配置されると、カバー３が閉じられる。このカバー３が閉じたことを装置本体２が検知することで、または、スイッチ等が操作されることで、複数の検知ユニットのそれぞれにおいて、光源２３が光を射出すると共に、受光部２４が光を受光する。複数の受光部２４のそれぞれは、受光強度に応じた強度の電気信号を検出部２５にそれぞれ出力する。検出部２５は、各受光部２４から受信した電気信号の強度が閾値を超えるか否かで、検知ユニット毎、即ち、ブリスターパック９の収容部９１毎の内容物９２の有無をそれぞれ検出し、検出結果を電波で出力する。   The cover 3 is opened (see FIG. 2), and the blister pack 9 is disposed on the housing member 22 so that each housing portion 91 is housed. When the blister pack 9 is placed, the cover 3 is closed. When the apparatus main body 2 detects that the cover 3 is closed or a switch or the like is operated, the light source 23 emits light and the light receiving unit 24 emits light in each of the plurality of detection units. Is received. Each of the plurality of light receiving units 24 outputs an electrical signal having an intensity corresponding to the received light intensity to the detection unit 25. The detection unit 25 detects the presence or absence of the contents 92 for each detection unit, that is, for each storage unit 91 of the blister pack 9, depending on whether or not the intensity of the electrical signal received from each light receiving unit 24 exceeds a threshold value. The detection result is output by radio waves.

以上の内容物検知装置１では、光源２３から射出された光を受光部２４によって受光したときに、受光強度が変化することを利用して、ブリスターパック９の収容部９１の内容物９２の有無を検知する。即ち、内容物検知装置１では、光源２３と受光部２４との間にブリスターパック９の一部（例えば、内容物９２を押し出した後の潰れた状態の収容部や、収容部９１の開口を塞いでいたシート）があっても、収容部９１内の内容物９２の有無を検知することができる。   In the content detection apparatus 1 described above, the presence / absence of the content 92 in the accommodating portion 91 of the blister pack 9 is utilized by utilizing the fact that the light reception intensity changes when the light emitted from the light source 23 is received by the light receiving portion 24. Is detected. That is, in the content detection apparatus 1, a part of the blister pack 9 (for example, a collapsed storage part after the content 92 is pushed out or an opening of the storage part 91 is provided between the light source 23 and the light receiving part 24. Even if there is a closed sheet), the presence or absence of the contents 92 in the housing portion 91 can be detected.

具体的には、本実施形態の内容物検知装置１では、受光部２４から出力される電気信号の強度に対する適切な閾値を設定し、検出部２５において受光部２４から受信した電気信号の強度がこの閾値を超えるか否かでブリスターパック９の収容部９１内の内容物９２の有無を検出する構成とすることで、光源２３と、この光源２３から射出された光を受光する受光部２４との間、即ち、光源２３から受光部２４に向かう光の軌道上に物体（ブリスターパック９の一部）があったとしても、収容部９１内の内容物９２の有無を検知することができる。   Specifically, in the content detection device 1 of the present embodiment, an appropriate threshold is set for the intensity of the electrical signal output from the light receiving unit 24, and the intensity of the electrical signal received from the light receiving unit 24 is detected by the detection unit 25. By adopting a configuration for detecting the presence or absence of the contents 92 in the accommodating portion 91 of the blister pack 9 based on whether or not this threshold value is exceeded, the light source 23 and the light receiving portion 24 that receives the light emitted from the light source 23 are provided. Even if there is an object (a part of the blister pack 9) on the light path from the light source 23 toward the light receiving unit 24, the presence or absence of the contents 92 in the storage unit 91 can be detected.

本実施形態の内容物検知装置１では、検出部２５が複数の検知ユニット（一つの内壁面２２０と、この内壁面２２０に対応する光源２３および受光部２４）のそれぞれから電気信号を受信すると共に、検知ユニット毎の収容部９１内の内容物９２の有無を検出しているため、複数の収容部９１を有するブリスターパック９の収容部９１毎の内容物９２の有無を検知することができる。   In the content detection apparatus 1 of the present embodiment, the detection unit 25 receives electrical signals from each of a plurality of detection units (one inner wall surface 220 and the light source 23 and the light receiving unit 24 corresponding to the inner wall surface 220). Since the presence / absence of the contents 92 in the accommodating portion 91 for each detection unit is detected, the presence / absence of the contents 92 for each accommodating portion 91 of the blister pack 9 having the plurality of accommodating portions 91 can be detected.

また、本実施形態の内容物検知装置１では、周面部２６２が、円柱面状であり、光源２３と受光部２４とが、周面部２６２において、該周面部２６２の径方向に対向する位置に配置されている。このため、受光部２４が周面部２６２の周方向において光源２３から最も離れた位置に配置される。   Further, in the content detection device 1 of the present embodiment, the peripheral surface portion 262 has a cylindrical surface shape, and the light source 23 and the light receiving portion 24 are located at positions facing the radial direction of the peripheral surface portion 262 in the peripheral surface portion 262.
