Description
【０００１】[0001]
本考案は、移動体の移動状態などを検出精度良く検出できるフォトセンサ組立 体に関するものである。 The present invention relates to a photo sensor assembly capable of detecting a moving state of a moving body with high detection accuracy.
【０００２】[0002]
発光素子と受光素子とから構成された１組のフォトセンサは、移動体の位置を 検出したり、あるいは、移動体の通過状態を検出できるので、各種の自動機器に 多用されている。 One set of photosensors, which are composed of a light emitting element and a light receiving element, can detect the position of a moving body or the passing state of the moving body, and are therefore widely used in various automatic devices.
【０００３】 上記フォトセンサは、発光素子と受光素子とを樹脂材などの基台を用いて反射 型又は透過型として小型一体に成形して使用する場合と、それぞれ別体に形成し た発光素子と受光素子とを所定の間隔を離して互いに対向するよう基台に取り付 けて透過型として使用する場合とがある。 前者の場合には、発光素子と受光素子間の距離が比較的小さく、小型一体に組み 立てられているので使い易いが、設置時の自由度はある程度制限される。これに 対して後者の場合には、発光素子と受光素子とを自由に設置できるので、発光素 子と受光素子間の距離を比較的大きく設定できると共に、小型一体のフォトセン サを取り付けることができない箇所にも適用できるなどの利点がある。In the above photo sensor, a light emitting element and a light receiving element are integrally molded as a reflective type or a transmissive type using a base made of a resin material or the like, and a light emitting element formed separately. There is a case in which the light receiving element and the light receiving element are mounted on a base so as to face each other with a predetermined distance and used as a transmission type. In the former case, the distance between the light-emitting element and the light-receiving element is relatively small, and it is easy to use because it is assembled in a small size, but the degree of freedom during installation is limited to some extent. On the other hand, in the latter case, the light emitting element and the light receiving element can be freely installed, so that the distance between the light emitting element and the light receiving element can be set relatively large, and a small integrated photosensor can be attached. It has the advantage that it can be applied to places that cannot.
【０００４】 ここでは、後者のフォトセンサを採用した例について述べる。Here, an example in which the latter photo sensor is adopted will be described.
【０００５】 図３は従来のフォトセンサ組立体を採用した多装填カセット記録・再生装置を 示した斜視図、図４は従来のフォトセンサ組立体を拡大して示した側断面図であ る。FIG. 3 is a perspective view showing a multi-load cassette recording / reproducing apparatus adopting a conventional photo sensor assembly, and FIG. 4 is an enlarged side sectional view showing the conventional photo sensor assembly.
【０００６】 図３に示した多装填カセット記録・再生装置１において、ラック２には磁気テ ープとかディスクなどの記録媒体３を収納したカセット４が垂直方向に複数積層 されている。上記カセット４は、後述するフォトセンサ組立体によりカセット４ の移動状態などを検出される移動体となるものである。In the multi-loading cassette recording / reproducing apparatus 1 shown in FIG. 3, a plurality of cassettes 4 accommodating recording media 3 such as magnetic tapes or disks are vertically stacked on a rack 2. The cassette 4 serves as a moving body whose movement state and the like are detected by a photo sensor assembly described later.
【０００７】 また、ラック２と対向する奥方には、カセット４に収納した記録媒体３を駆動 する記録媒体駆動装置５が複数段積みして設置されている。ここでは３台の記録 媒体駆動装置５を段積みして設置している。Further, a plurality of recording medium driving devices 5 for driving the recording mediums 3 housed in the cassette 4 are stacked and installed in the rear opposite to the rack 2. Here, three recording medium driving devices 5 are stacked and installed.

The cassette transporting device 6 selectively takes out a desired cassette 4 from the rack 2 and selectively transports it to a desired recording medium driving device 5, and selectively drives the desired cassette 4 to a desired recording medium driving device 5. It has a function of inserting the desired cassette 4 to the original rack 2 after the recording medium 3 is driven in the desired recording medium driving device 5 while being inserted into the insertion slot 5a of the same.
【０００９】 また、上記カセット搬送装置６では、垂直方向に移動自在なベース台７の左右 側方にタイミングプーリ８，８及びタイミングプーリ９，９を介して一対のタイ ミングベルト１０，１０が張架されている。これらのタイミングベルト１０，１ ０はゴムなどの摩擦部材を用いて無端ベルトに形成されており、内側にタイミン グプーリ８，９と噛合する歯形が形成されている。Further, in the cassette carrying device 6, a pair of timing belts 10 and 10 are stretched on the left and right sides of a vertically movable base base 7 via timing pulleys 8 and 8 and timing pulleys 9 and 9, respectively. It is hung. These timing belts 10 and 10 are formed as endless belts by using a friction member such as rubber, and have a tooth profile that meshes with the timing pulleys 8 and 9 inside.
【００１０】 また、記録媒体駆動装置５に形成した挿入口５ａの左右両側には、それぞれ別 体に形成した発光素子１１と受光素子１２とで１組のフォトセンサを構成し、そ れぞれの挿入口５ａに対応して複数組のフォトセンサが設置されている。 即ち、挿入口５ａの左側に設けた第１基台１３には、複数の発光素子１１のみが 略同一線上で垂直方向に一列にそれぞれの挿入口５ａに対応して配設され、発光 素子１１側のフォトセンサ組立体として構成されている。 一方、挿入口５ａの右側で第１基台１３と対向して設けた第２基台１４には、複 数の受光素子１２のみが上記複数の発光素子１１と対向しながら略同一線上で垂 直方向に一列にそれぞれの挿入口５ａに対応して配設され、受光素子１２側のフ ォトセンサ組立体として構成されている。Further, on the left and right sides of the insertion port 5a formed in the recording medium driving device 5, a pair of photosensors are formed by the light emitting element 11 and the light receiving element 12 which are separately formed, and each set has a photosensor. A plurality of sets of photosensors are installed in correspondence with the insertion openings 5a. That is, on the first base 13 provided on the left side of the insertion port 5a, only the plurality of light emitting elements 11 are arranged substantially in a line in the vertical direction in a line corresponding to the respective insertion ports 5a. Side photosensor assembly. On the other hand, on the second base 14 provided on the right side of the insertion opening 5a so as to face the first base 13, only a plurality of light receiving elements 12 are suspended on the substantially same line while facing the plurality of light emitting elements 11. The photosensors are arranged in a straight line in a row corresponding to the respective insertion openings 5a, and are configured as a photosensor assembly on the light receiving element 12 side.
【００１１】 そして、ラック２から取り出した所望のカセット４の左右両側を一対のタイミ ングベルト１０，１０で把持しながら、左方のタイミングベルト１０を反時計方 向，右方のタイミングベルト１０を時計方向に回転させることにより、所望のカ セット４を一時的にベース台７に搬送し、更に、このベース台７を所望の記録媒 体駆動装置５の挿入口５ａまで垂直方向に移動して、ベース台７から所望のカセ ット４を所望の記録媒体駆動装置５内に挿入している。 ここで、挿入口５ａの左右に設けた発光素子１１と受光素子１２とで構成された 複数組のフォトセンサにより、所望のカセット４が完全に所望の記録媒体駆動装 置５内に挿入された時、１組の発光素子１１から照射された光は、これと対向す る受光素子１２で受光できるので、所望のカセット４が挿入されたことを検出し 、その後所望の記録媒体駆動装置４により記録媒体３を記録及び／又は再生して いる。While holding the left and right sides of the desired cassette 4 taken out from the rack 2 with the pair of timing belts 10 and 10, the left timing belt 10 is counterclockwise and the right timing belt 10 is clocked. By rotating in the direction, the desired cassette 4 is temporarily transported to the base table 7, and further this base table 7 is moved vertically to the insertion port 5a of the desired recording medium driving device 5, The desired cassette 4 is inserted into the desired recording medium driving device 5 from the base 7. Here, the desired cassette 4 is completely inserted into the desired recording medium driving device 5 by the plurality of sets of photosensors each including the light emitting element 11 and the light receiving element 12 provided on the left and right of the insertion opening 5a. At this time, the light emitted from the pair of light emitting elements 11 can be received by the light receiving element 12 facing the light emitting element 11, so that it is detected that the desired cassette 4 is inserted, and then the desired recording medium driving device 4 is used. The recording medium 3 is recorded and / or reproduced.
【００１２】[0012]
ところで、従来のフォトセンサ組立体を採用した多装填カセット記録・再生装 置１では、それぞれ別体に形成した発光素子１１と受光素子１２とで１組のフォ トセンサを構成し、且つ、複数段積み設置した記録媒体駆動装置５のそれぞれの 挿入口５ａの左右両側に複数組のフォトセンサを設置し、所望のカセット４が所 望の記録媒体駆動装置５内に挿入されたことを検出している。 この際、図４にも拡大して示したように、挿入口５ａの左側に設けた第１基台１ ３には、複数の発光素子１１のみが略同一線上で垂直方向に一列にそれぞれの挿 入口５ａに対応して配設され、一方、挿入口５ａの右側に設けた第２基台１４に は、複数の受光素子１２のみが上記複数の発光素子１１と対向しながら略同一線 上で垂直方向に一列にそれぞれの挿入口５ａに対応して配設されている。 従って、一つの発光素子１１から照射された光は、同一水平線上で一つの発光素 子１１と対向する受光素子１２で受光できるものの、一つの発光素子１１から照 射された光が照射角θの範囲に拡散しているので、同一水平線上で対向する受光 素子１２と隣り合う他の組みの受光素子１２，１２にも影響を及ぼしてしまい、 所望のカセット４が所望の記録媒体駆動装置５内に挿入されたことを検出できる ものの、他の記録媒体駆動装置５内にも挿入されたと判断されるなどの現象が生 じてしまう。これにより、発光素子１１側のフォトセンサ組立体と受光素子１２ 側のフォトセンサ組立体とで構成された複数組のフォトセンサが誤検出するなど の問題が生じている。 By the way, in the multi-loading cassette recording / reproducing apparatus 1 employing the conventional photosensor assembly, one set of photosensors is constituted by the light emitting element 11 and the light receiving element 12 which are separately formed, and a plurality of stages are provided. A plurality of sets of photosensors are installed on the left and right sides of the respective insertion openings 5a of the stacked recording medium driving devices 5, and it is detected that the desired cassette 4 is inserted into the desired recording medium driving device 5. There is. At this time, as shown in FIG. 4 in an enlarged manner, only the plurality of light emitting elements 11 are arranged substantially in the same line in a vertical direction on the first base 13 provided on the left side of the insertion opening 5a. On the other hand, on the second base 14 provided on the right side of the insertion port 5a, only the plurality of light receiving elements 12 are arranged on the substantially same line while facing the plurality of light emitting elements 11. Are arranged in a line in the vertical direction corresponding to the respective insertion openings 5a. Therefore, although the light emitted from one light emitting element 11 can be received by the light receiving element 12 which faces the one light emitting element 11 on the same horizontal line, the light emitted from one light emitting element 11 has an irradiation angle θ. Since it is diffused in the range, the light receiving elements 12 facing each other on the same horizontal line also affect the other light receiving elements 12 and 12 adjacent to each other, so that the desired cassette 4 can drive the desired recording medium driving device 5 Although it can be detected that it has been inserted into the other recording medium driving device, a phenomenon such that it is judged that the recording medium driving device 5 is also inserted into another recording medium driving device 5 occurs. This causes a problem such as erroneous detection by a plurality of sets of photosensors configured by the photosensor assembly on the light emitting element 11 side and the photosensor assembly on the light receiving element 12 side.
【００１３】[0013]
本考案は上記課題に鑑みてなされたものであり、それぞれ別体に形成した発光 素子と受光素子とを第１の間隔を離して対向させて１組のフォトセンサを構成し て成り、 前記発光素子と前記受光素子とを第１基台の一方向に略第２の間隔を離して交互 に配設した第１のフォトセンサ組立体と、 前記第１基台と略平行で前記第１の間隔を離して対向する第２基台に、前記第１ 基台側のそれぞれの発光，受光素子と１組づづのフォトセンサを構成する受光， 発光素子を対向して配設した第２のフォトセンサ組立体とを具備したことを特徴 とするフォトセンサ組立体を提供するものである。 The present invention has been made in view of the above problems, and is configured by forming a pair of photosensors by separately forming a light emitting element and a light receiving element that face each other with a first gap therebetween. A first photosensor assembly in which the elements and the light receiving elements are alternately arranged in one direction of the first base at a substantially second distance, and the first photosensor assembly is substantially parallel to the first base. A second photo in which the light-emitting elements on the first base side and the light-receiving elements that constitute one set of photosensors and the light-emitting elements are arranged on the second base elements that face each other at a distance.

以下に本考案に係わるフォトセンサ組立体の一実施例を図１乃至図２を参照し て詳細に説明する。 尚、説明の便宜上、先に示した構成部材と同一構成部材に対しては同一の符号を 付し、詳細な説明は省略すると共に、先に示した構成部材は必要に応じて適宜説 明し、従来と異なる箇所を中心に説明する。 An embodiment of a photo sensor assembly according to the present invention will be described in detail below with reference to FIGS. For convenience of explanation, the same components as those shown above are designated by the same reference numerals, detailed description thereof will be omitted, and the components shown above will be appropriately described as necessary. A description will be given focusing on the points different from the conventional one.

It is a figure.
【００１６】 本考案に係わるフォトセンサ組立体では、それぞれ別体に形成した発光素子１ １と受光素子１２とを第１の間隔Ｌ１を離して対向させて１組のフォトセンサを 構成し、且つ、発光素子１１と受光素子１２とを第１基台１３の一方向に略第２ の間隔Ｌ２を離して交互に配設した第１のフォトセンサ組立体１３Ａと、第１基 台１３と略平行で第１の間隔Ｌ１を離して対向する第２基台１４に、第１基台１ ３側のそれぞれの発光，受光素子１１，１２と１組づづのフォトセンサを構成す る受光，発光素子１２，１１を対向して配設した第２のフォトセンサ組立体１４ Ａとでフォトセンサ組立体を組立てたことを技術思想とするものである。In the photosensor assembly according to the present invention, the light emitting element 11 and the light receiving element 12 which are separately formed are opposed to each other with a first distance L 1 therebetween to form a set of photosensors. In addition, the first photosensor assembly 13A and the first base 13 in which the light emitting elements 11 and the light receiving elements 12 are alternately arranged in one direction of the first base 13 with a substantially second distance L 2 therebetween. A pair of photosensors including the light-emitting and light-receiving elements 11 and 12 on the side of the first base 13 are formed on a second base 14 that is substantially parallel to and faces the first base 13 with a first gap L 1 therebetween. The technical idea is to assemble the photo sensor assembly with the second photo sensor assembly 14A in which the light receiving and light emitting elements 12 and 11 are arranged so as to face each other.
【００１７】 図１に示した多装填カセット記録・再生装置１において、前述した従来例と異 なる箇所は、それぞれ別体に形成した発光素子１１と受光素子１２とで１組のフ ォトセンサを構成し、且つ、複数段積み設置した記録媒体駆動装置５に形成した それぞれの挿入口５ａの左右両側に複数組設置する際、発光素子１１と受光素子 １２の配設状態が従来例と異なっている。In the multi-load cassette recording / reproducing apparatus 1 shown in FIG. 1, a portion different from the above-mentioned conventional example constitutes a pair of photosensors with a light emitting element 11 and a light receiving element 12 which are separately formed. In addition, when a plurality of sets are installed on the left and right sides of the respective insertion openings 5a formed in the recording medium driving device 5 which is stacked and installed in plural stages, the arrangement state of the light emitting element 11 and the light receiving element 12 is different from the conventional example. .
【００１８】 即ち、挿入口５ａの左側に設けた第１基台１３と、挿入口５ａの右側に設けた 第２基台１４とは、挿入口５ａの巾寸法程度の第１の間隔Ｌ１（図２）を離して 互いに対向しており、この間隔内に移動体となるカセット４が矢印Ｙ１，Ｙ２方 向及び矢印Ｚ１，Ｚ２方向に移動自在となっている。That is, the first base 13 provided on the left side of the insertion opening 5a and the second base 14 provided on the right side of the insertion opening 5a have a first spacing L 1 about the width dimension of the insertion opening 5a. (Fig. 2) are separated from each other, and the cassette 4 serving as a moving body is movable in the directions Y 1 and Y 2 and Z 1 and Z 2 within this interval.
【００１９】 また、挿入口５ａの左側に設けた第１基台１３には、上方から発光素子１１と 受光素子１２とが略同一線上で垂直方向（一方向）にそれぞれの挿入口５ａに対 応する略第２の間隔Ｌ２（図２）を離して交互に配設されて、第１のフォトセン サ組立体１３Ａとして組立てられている。 一方、挿入口５ａの右側に設けた第２基台１４には、第１基台１３側のそれぞれ の素子１１，１２と１組づづのフォトセンサを構成するよう、即ち、上方から受 光素子１２と発光素子１１とが略同一線上で垂直方向に一列にそれぞれの挿入口 ５ａに対応する略第２の間隔Ｌ２（図２）を離して交互に配設されて、第２のフ ォトセンサ組立体１４Ａとして組立てられている。In addition, on the first base 13 provided on the left side of the insertion port 5a, the light emitting element 11 and the light receiving element 12 are vertically aligned (in one direction) with respect to the respective insertion ports 5a from above. Accordingly, the first photosensor assembly 13A is assembled by alternately arranging the corresponding second intervals L 2 (FIG. 2). On the other hand, in the second base 14 provided on the right side of the insertion port 5a, one set of photosensors is formed with the respective elements 11 and 12 on the side of the first base 13, that is, the light receiving element from above. 12 and the light-emitting elements 11 are alternately arranged in a line in the vertical direction on substantially the same line and separated from each other by a substantially second interval L 2 (FIG. 2) corresponding to the respective insertion openings 5a. It is assembled as an assembly 14A.
【００２０】 また、図２にも拡大して示したように、第１基台１３に配設した発光素子１１ 及び第２基台１４に配設した発光素子１１から照射される光１２は、前述したよ うに照射角θの範囲に拡散している。 ここで、第１基台１３と第２基台１３との間隔を第１の間隔Ｌ１と設定し、一方 、第１，第２基台１３，１４に配設した隣り合う発光，受光素子１１，１２の間 隔を第２の間隔Ｌ２と設定すると、 Ｌ１×ｔａｎθ／２＜２×Ｌ２ ……となるように、第１の間隔Ｌ１に対し て発光素子１１の照射角θをあらかじめ選定し、第２の間隔Ｌ２を設定している 。 従って、一つの発光素子１１から照射された光は、同一水平線上で一つの発 光素子１１と対向する受光素子１２で確実に受光でき、しかも、一つの発光素子 １１に対向する受光素子１２と同一側の上下隣り合う発光素子１１，１１には一 つの発光素子１１から照射された光が照射されても、発光素子１１のため何らの 支障ず生じない。更に、上記式を満足するように受光素子１２と同一側で略２ ×Ｌ２の間隔を離した他の組の受光素子１２が配設されているため、一つの発光 素子１１から照射された光は、他の組の受光素子１２にも何らの影響も与えない 。 従って、それぞれ別体に形成した発光素子１１と受光素子１２とを第１の間 隔Ｌ１を離して対向させて１組のフォトセンサを構成し、第１，第２基台１３， １４の一方向に複数組のフォトセンサを上記のように配設することにより、互い に対向する１組のフォトセンサのみが確実に検出動作をし、他の組のフォトセン サには全く何らの影響を与えないので、フォトセンサ組立体（１３Ａ，１４Ａ） の品質向上及び信頼性向上に寄与できる。Further, as shown in an enlarged view in FIG. 2, the light 12 emitted from the light emitting element 11 arranged on the first base 13 and the light emitting element 11 arranged on the second base 14 is As described above, it diffuses within the range of the irradiation angle θ. Here, the interval between the first base 13 and the second base 13 is set as the first interval L 1 , while the adjacent light emitting / receiving elements arranged on the first and second bases 13 and 14 are arranged. When the distance between 11 and 12 is set as the second distance L 2 , the irradiation angle of the light emitting element 11 with respect to the first distance L 1 becomes as follows: L 1 × tan θ / 2 <2 × L 2 θ is selected in advance and the second interval L 2 is set. Therefore, the light emitted from one light emitting element 11 can be reliably received by the light receiving element 12 facing the one light emitting element 11 on the same horizontal line, and the light receiving element 12 facing the one light emitting element 11 can be surely received. Even if the light emitted from one light emitting element 11 is applied to the light emitting elements 11, 11 that are vertically adjacent to each other on the same side, no problem occurs due to the light emitting element 11. Further, since another set of light receiving elements 12 spaced apart by about 2 × L 2 is arranged on the same side as the light receiving element 12 so as to satisfy the above expression, light is emitted from one light emitting element 11. The light does not affect the other sets of the light receiving elements 12 at all. Therefore, the light emitting element 11 and the light receiving element 12 which are separately formed are opposed to each other with the first gap L 1 therebetween to form a set of photosensors, and the photosensors of the first and second bases 13 and 14 are formed. By arranging multiple sets of photosensors in one direction as described above, only one set of photosensors facing each other can surely perform the detection operation, and the other sets of photosensors are not affected at all. Since it is not provided, the quality and reliability of the photosensor assembly (13A, 14A) can be improved.
【００２１】 そして、本考案に係わるフォトセンサ組立体（１３Ａ，１４Ａ）を採用した多 装填カセット記録・再生装置１においては、移動体となる所望のカセット４が所 望の記録媒体駆動装置５内に挿入されたことを確実に検出できると共に、従来の ように他の記録媒体駆動装置５内にも挿入されたと検出するような誤検出がなく なり、多装填カセット記録・再生装置１の品質向上及び信頼性向上に寄与できる 。In the multi-loading cassette recording / reproducing apparatus 1 employing the photosensor assembly (13A, 14A) according to the present invention, the desired cassette 4 to be the moving body is inside the desired recording medium driving device 5. It is possible to reliably detect that the multi-loading cassette recording / reproducing apparatus 1 has been inserted, and the erroneous detection of detecting that it has also been inserted into another recording medium driving apparatus 5 as in the past is eliminated. And can contribute to improving reliability.
【００２２】 尚、実施例では、本考案に係わるフォトセンサ組立体（１３Ａ，１４Ａ）を、 移動体となる所望のカセット４が所望の記録媒体駆動装置５内に挿入されたか否 かの検出用として説明したが、これに限ることなく、例えば移動体（カセット４ ）が矢印Ｚ１，Ｚ２方向に移動する状態も検出可能であり、更に、各種の自動機 器における移動体の移動状態などを検出することも可能となり、多用性のあるフ ォトセンサ組立体を提供できる。In the embodiment, the photosensor assembly (13A, 14A) according to the present invention is used for detecting whether or not a desired cassette 4 as a moving body is inserted into a desired recording medium driving device 5. However, the present invention is not limited to this, and it is possible to detect, for example, the state in which the moving body (cassette 4) moves in the directions of the arrows Z 1 and Z 2 , and further, the moving state of the moving body in various automatic devices, etc. Can be detected, and a versatile photo sensor assembly can be provided.

以上詳述した本考案に係わるフォトセンサ組立体によると、それぞれ別体に形 成した発光素子と受光素子とを第１の間隔を離して対向させて１組のフォトセン サを構成し、且つ、発光素子と受光素子とを第１基台の一方向に略第２の間隔を 離して交互に配設した第１のフォトセンサ組立体と、第１基台と略平行で第１の 間隔を離して対向する第２基台に、第１基台側のそれぞれの発光，受光素子と１ 組づづのフォトセンサを構成する受光，発光素子を対向して配設した第２のフォ トセンサ組立体とでフォトセンサ組立体を組立てたため、一つの発光素子から照 射された光は、一つの発光素子と対向する受光素子で確実に受光でき、しかも、 一つの発光素子に対向する受光素子と同一側の隣り合う発光素子には一つの発光 素子から照射された光が照射されても、発光素子のため何らの支障ず生じない。 更に、一つの発光素子から照射された光は、一つの発光素子に対向する受光素子 と同一側で間隔を離した他の組の受光素子にも何らの影響も与えない。 従って、互いに対向する１組のフォトセンサのみが確実に検出動作をし、他の組 のフォトセンサには何らの影響を与えないので、フォトセンサ組立体の品質向上 及び信頼性向上に寄与でき、各種の自動機器における移動体の移動状態などを検 出することが可能となり、多用性のあるフォトセンサ組立体を提供できる。 According to the photo sensor assembly according to the present invention described in detail above, the light emitting element and the light receiving element, which are separately formed, are opposed to each other with a first distance therebetween, and a pair of photo sensors are formed. , A first photosensor assembly in which a light emitting element and a light receiving element are alternately arranged in one direction of the first base at a substantially second distance, and a first space substantially parallel to the first base. A second photosensor assembly in which the light-receiving and light-emitting elements that constitute one set of light-emitting and light-receiving elements on the side of the first base are arranged opposite to each other on the second base that faces each other. Since the photo sensor assembly is assembled with the three-dimensional structure, the light emitted from one light emitting element can be reliably received by the light receiving element facing one light emitting element, and the light receiving element facing one light emitting element Adjacent light emitting elements on the same side are illuminated by one light emitting element. And even if the light is irradiated, no not a no hindrance for the light emitting element. Further, the light emitted from one light emitting element does not have any influence on the other light receiving elements which are spaced apart on the same side as the light receiving element facing the one light emitting element. Therefore, only one set of photosensors facing each other surely performs the detection operation and has no influence on the other set of photosensors, which can contribute to the quality improvement and reliability improvement of the photosensor assembly. It is possible to detect the moving state of the moving body in various automatic devices, and it is possible to provide a versatile photo sensor assembly.
