Description
【０００１】[0001]
この考案は荷物検出装置、特にロッカー内の荷物の有無を検出するロッカー用 荷物検出装置に関連する。 The present invention relates to a luggage detection device, and more particularly to a luggage detection device for a locker that detects the presence or absence of luggage in the locker.
【０００２】[0002]
ロッカー内の荷物の有無を検出するロッカー用荷物検出装置は公知である。例 えば、図４に示すように従来のロッカー用荷物検出装置は、ロッカー２１と、ロ ッカー２１の左側壁部２１aの下部に取り付けられた発光部２２と、ロッカー２ １の右側壁部２１bの下部に取り付けられかつ発光部２２から照射された光２４ を受光する受光部２３と、受光部２３から送出された信号を受信し空間内の荷物 の有無を検出する荷物検出回路（図示せず）を備えている。発光部２２には発光 ダイオード等からなる発光素子が設けられ、受光部２３にはフォトダイオード、 フォトトランジスタ等からなる受光素子が設けられる。また、図示しないがロッ カー２１内又は外に設けられるＬＳＩ等のワンチップマイクロコンピュータ等で 構成される荷物検出回路が受光部２３に電気的に接続される。荷物がロッカー１ の空間内に配置されたとき、発光部２２から照射された光２４が遮断されかつ受 光部２３が光２４を受光しなくなることによって、荷物検出回路が作動しロッカ ー１内の荷物が検出される。 A locker luggage detection device for detecting the presence or absence of luggage in the locker is known. For example, as shown in FIG. 4, the conventional locker baggage detection device includes a rocker 21, a light emitting unit 22 attached to the lower part of the left side wall 21a of the rocker 21, and a right side wall 21b of the rocker 21. A light receiving unit 23 attached to the lower portion and receiving the light 24 emitted from the light emitting unit 22, and a package detection circuit (not shown) for receiving the signal transmitted from the light receiving unit 23 and detecting the presence or absence of the package in the space Is equipped with. The light emitting section 22 is provided with a light emitting element such as a light emitting diode, and the light receiving section 23 is provided with a light receiving element such as a photodiode and a phototransistor. Further, although not shown, a package detection circuit configured by a one-chip microcomputer such as an LSI provided inside or outside the locker 21 is electrically connected to the light receiving unit 23. When the luggage is placed in the space of the locker 1, the light 24 emitted from the light emitting unit 22 is blocked and the light receiving unit 23 does not receive the light 24, so that the luggage detection circuit operates and the inside of the locker 1 is operated. Luggage is detected.
【０００３】[0003]
ところで、従来のロッカー用荷物検出装置では、空間内に荷物が配置されてい ないとき、発光部から照射された光を、荷物を配置する空間を介しかつ発光部に 相対して配置された受光素子で直接受光していた。このとき、荷物を配置する空 間内に一本の光路が形成されるから、空間内に配置された荷物がこの一本の光路 を遮断することによって、ロッカー内の荷物を検出していた。このため、ロッカ ー内において、荷物を配置する空間内に形成された一本の光路から外れた位置に 荷物が配置され、一本の光路を遮断しないときはロッカー内の荷物を検出できな い欠点があった。従って、ロッカー内の荷物の置き場所が制限される問題があっ た。 By the way, in the conventional locker luggage detection device, when the luggage is not placed in the space, the light emitted from the light emitting unit is placed in the light receiving element through the space where the luggage is placed and facing the light emitting unit. It was receiving light directly at. At this time, since one optical path is formed in the space where the luggage is placed, the luggage placed in the space detects the luggage inside the locker by blocking this one optical path. For this reason, in the locker, the luggage is placed at a position outside the one optical path formed in the space where the luggage is placed, and the luggage in the locker cannot be detected unless the one optical path is blocked. There was a flaw. Therefore, there is a problem that the storage place of the luggage in the locker is limited.
【０００４】 そこで、この考案ではロッカー内のいずれの場所に荷物を配置しても、荷物の 検出が可能なロッカー用荷物検出装置を提供することを目的とする。Therefore, an object of the present invention is to provide a luggage detection device for a locker, which can detect the luggage regardless of the location of the luggage in the locker.
【０００５】[0005]
この考案によるロッカー用荷物検出装置は、発光素子を有する発光部と、荷物 を配置する空間を介して配置されると共に発光部から照射された光を受光する受 光素子を有する受光部と、受光部から送出された信号を受信し空間内の荷物の有 無を検出する荷物検出回路とを備えている。このロッカー用荷物検出装置は、荷 物を配置する空間を介して互いに離間して配置されかつ発光部から照射された光 を複数回反射させる一対の反射鏡を備えている。また、このロッカー用荷物検出 装置は、ルーバを介して一対の反射鏡の間で光が反射される。反射鏡の端部には 発光部と受光部が設けられる。 The locker luggage detection device according to the present invention comprises a light emitting portion having a light emitting element, a light receiving portion having a light receiving element for receiving light emitted from the light emitting portion, the light receiving portion being disposed through a space for placing the luggage. And a package detection circuit for detecting the presence or absence of a package in the space by receiving a signal transmitted from the unit. This locker luggage detection device is provided with a pair of reflecting mirrors which are arranged apart from each other through a space in which a load is placed and which reflects the light emitted from the light emitting section a plurality of times. Further, in this locker luggage detection device, light is reflected between the pair of reflecting mirrors via the louver. A light emitting portion and a light receiving portion are provided at the end of the reflecting mirror.
【０００６】[0006]
この考案によるロッカー用荷物検出装置は、荷物が空間内に配置されていない とき、荷物を配置する空間を介して互いに離間して配置された一対の反射鏡間で 発光素子の発光部から照射された光が複数回反射される。この反射された光は受 光素子によって受光される。このとき、荷物を配置する空間には複数本の光路が 形成される。荷物が空間内に配置されたとき、複数本の光路のうちの何本かが荷 物によって遮断され、受光素子が光を受光しなくなることによって、荷物検出回 路が作動しロッカー内の荷物の検出が行われる。 According to the locker luggage detection device of the present invention, when the luggage is not placed in the space, the light is emitted from the light emitting portion of the light emitting element between the pair of reflecting mirrors spaced apart from each other through the space in which the luggage is placed. The reflected light is reflected multiple times. The reflected light is received by the light receiving element. At this time, a plurality of optical paths are formed in the space where the luggage is placed. When the load is placed in the space, some of the multiple optical paths are blocked by the load, and the light receiving element stops receiving light. Detection is done.
