Description

この発明は、例えば現金自動預け払い機、複写機やプリンタに用いられる光電センサの取付機構に関する。   The present invention relates to a photoelectric sensor mounting mechanism used in, for example, an automatic teller machine, a copying machine, and a printer.

現金自動預け払い機、複写機やプリンタ等では、紙葉の位置、搬送速度、収納庫内の紙葉の有無等を監視するために、受光センサと発光センサまたは受発光センサ（以下、これらを光電センサと呼ぶ。）が所定の位置に配置されている。   In automatic teller machines, copiers, printers, etc., a light receiving sensor and a light emitting sensor or a light receiving / emitting sensor (hereinafter referred to as these) are used to monitor the position of the paper sheet, the conveyance speed, and the presence or absence of paper sheets in the storage. (Referred to as a photoelectric sensor) is disposed at a predetermined position.

従来の光電センサ取付け機構は、図７に示すように、光電センサ１１００と、この光電センサ１１００を固定するブラケット１２０１と、紙葉類をガイドする搬送ガイド１２０２とで構成されている。図７（Ａ）は斜視図であり、図７（Ｂ）はＢ−Ｂ矢視断面図であり、図７（Ｃ）はＣ−Ｃ矢視断面図である。従来の光電センサ１１００は、従来の光電センサ１１００にある爪部１１０１をブラケット１２０１の溝部に引っ掛けることにより、ブラケット１２０１に固定されている。さらに、従来の光電センサ１１００は、搬送ガイド１２０２に空けられたセンサ孔１２０３に発光部、受光部、または受発光部（以下、これらをセンシング部と呼ぶ。）をはめ込むことにより搬送ガイド１２０２にも位置決めされている。センシング部は搬送路上に露出している。このような構成であるので、ブラケット１２０１と搬送ガイド１２０２の相対位置を適切に決めなければならない。また、従来の光電センサ１１００を搬送ガイド１２０２に固定するためにブラケット１２０１と爪部１１０１が必要であるので、その分の場所をとっていた。   As shown in FIG. 7, the conventional photoelectric sensor mounting mechanism includes a photoelectric sensor 1100, a bracket 1201 for fixing the photoelectric sensor 1100, and a conveyance guide 1202 for guiding paper sheets. 7A is a perspective view, FIG. 7B is a cross-sectional view taken along line BB, and FIG. 7C is a cross-sectional view taken along line CC. The conventional photoelectric sensor 1100 is fixed to the bracket 1201 by hooking the claw portion 1101 of the conventional photoelectric sensor 1100 into the groove portion of the bracket 1201. Further, the conventional photoelectric sensor 1100 has a light emitting unit, a light receiving unit, or a light emitting / receiving unit (hereinafter referred to as a sensing unit) fitted in the sensor hole 1203 formed in the conveyance guide 1202, so that the conveyance guide 1202 is also fitted. It is positioned. The sensing unit is exposed on the transport path. Because of such a configuration, the relative position of the bracket 1201 and the conveyance guide 1202 must be determined appropriately. Further, since the bracket 1201 and the claw portion 1101 are necessary to fix the conventional photoelectric sensor 1100 to the conveyance guide 1202, the space for that is taken up.

また、部品点数を少なくし、コスト低減を図ることを目的として、光電センサを搬送ガイドに固定するためのブラケットが搬送ガイドと一体となった構成である光電センサ取付け機構が示されている（特許文献１参照）。この光電センサ取付機構は、上述したブラケットと搬送ガイドの相対位置の決定は不要であるが、光電センサを固定するためのブラケットと爪部は必要である。   Further, for the purpose of reducing the number of parts and reducing the cost, there is shown a photoelectric sensor mounting mechanism in which a bracket for fixing the photoelectric sensor to the transport guide is integrated with the transport guide (patent) Reference 1). This photoelectric sensor mounting mechanism does not require determination of the relative position of the bracket and the conveyance guide described above, but requires a bracket and a claw for fixing the photoelectric sensor.

現金自動預け払い機の内部にある取付対象物としての搬送ガイド２０２に光電センサ３００を固定ピン５００で取り付けた光電センサ取付機構５０５について詳しく説明する。図１は光電センサ３００の斜視図であり、図２は図１とは別の角度から見た光電センサ３００の斜視図である。図３は固定ピン５００の正面図である。図４は搬送ガイドの斜視図である。図５は光電センサ３００の取り付け手順を示すための説明図である。図６は光電センサ３００と固定ピン５００が係合した状態を示す斜視図である。図面はすべて概略図である。   The photoelectric sensor attachment mechanism 505 in which the photoelectric sensor 300 is attached to the conveyance guide 202 as an attachment object inside the automatic teller machine by the fixing pin 500 will be described in detail. FIG. 1 is a perspective view of the photoelectric sensor 300, and FIG. 2 is a perspective view of the photoelectric sensor 300 viewed from an angle different from that of FIG. 1. FIG. 3 is a front view of the fixing pin 500. FIG. 4 is a perspective view of the conveyance guide. FIG. 5 is an explanatory diagram for illustrating a procedure for attaching the photoelectric sensor 300. FIG. 6 is a perspective view showing a state in which the photoelectric sensor 300 and the fixing pin 500 are engaged. All drawings are schematic.

光電センサ取付機構５０５は、光電センサ３００と固定ピン５００と搬送ガイド２０２から構成される。この光電センサ３００は、透過型の光電センサの投光側光電センサ、透過型の光電センサの受光側光電センサ、あるいは反射型の光電センサなど、適宜の光電センサで構成されている。   The photoelectric sensor mounting mechanism 505 includes a photoelectric sensor 300, a fixing pin 500, and a conveyance guide 202. This photoelectric sensor 300 is composed of an appropriate photoelectric sensor such as a light emitting side photoelectric sensor of a transmission type photoelectric sensor, a light receiving side photoelectric sensor of a transmission type photoelectric sensor, or a reflection type photoelectric sensor.

図１と図２に示すように、光電センサ３００は、全体が略直方体に形成されている。光電センサ３００の平面の中央部に短手方向のすべてが凹となっている平面視四角形の凹部３０３が設けられ、その両横に２つの当接部３０５が設けられている。この２つの当接部３０５は、いずれも平面視四角形で同一サイズ、同一形状に形成されており、光電センサ３００の平面の凹部３０３を挟んで左右対称に配置されている。当接部３０５の一方には、円盤形のセンシング部３０２が凸設されている。このセンシング部３０２は、投光部、受光部、受発光部のいずれであってもよく、センシング部３０２の角部３０４は面取りされている。   As shown in FIGS. 1 and 2, the entire photoelectric sensor 300 is formed in a substantially rectangular parallelepiped. A concave portion 303 having a rectangular shape in plan view that is concave in the short side direction is provided at the center of the plane of the photoelectric sensor 300, and two contact portions 305 are provided on both sides thereof. The two abutting portions 305 are square in plan view, are formed in the same size and shape, and are arranged symmetrically with respect to the concave portion 303 on the plane of the photoelectric sensor 300. On one side of the contact part 305, a disk-shaped sensing part 302 is projected. The sensing unit 302 may be any of a light projecting unit, a light receiving unit, and a light receiving / emitting unit, and a corner 304 of the sensing unit 302 is chamfered.

また、凹部３０３の平面視中央部から底面の中央部にかけて、当接部３０５に垂直な固定ピン貫通孔３０１が空けられている。光電センサ３００の底面は、板状部材４０４からなる。板状部材４０４は、固定ピン貫通孔３０１を囲む様に底面視Ｕ字状に溝孔４０３が設けられており、溝孔４０３の内側の板状部材が付勢手段である板バネ４０１として機能する。   Further, a fixing pin through hole 301 perpendicular to the contact portion 305 is opened from the central portion of the concave portion 303 in plan view to the central portion of the bottom surface. The bottom surface of the photoelectric sensor 300 is composed of a plate member 404. The plate-like member 404 is provided with a groove hole 403 in a U-shape when viewed from the bottom so as to surround the fixing pin through hole 301, and the plate-like member inside the groove hole 403 functions as a plate spring 401 that is an urging means. To do.

この板バネ４０１は、基部側が板状部材４０４に繋がっており、先端側に前述の固定ピン貫通孔３０１が設けられている。この固定ピン貫通孔３０１の周囲部分は、後述する固定ピン５００の第１固定部５０２が係合する係合部４０２として機能する。光電センサ３００の内部は、中空であり、適宜の電子部品が内蔵されている。   The leaf spring 401 is connected to the plate-like member 404 on the base side, and the fixing pin through hole 301 is provided on the tip side. The peripheral portion of the fixing pin through hole 301 functions as an engaging portion 402 with which a first fixing portion 502 of the fixing pin 500 described later is engaged. The inside of the photoelectric sensor 300 is hollow, and appropriate electronic components are incorporated.

図３に示すように、固定ピン５００には一端に先端部５０１が設けられており、他端に搬送ガイド２０２に固定するための突起である第２固定部５０３と第３固定部５０４が設けられている。先端部５０１は、先端が半球状に形成され、続いて逆円錐台形状で光電センサ３００に係合するための第１固定部５０２が形成されている。第１固定部５０２から第２固定部５０３までの距離Ｗ２は、光電センサ３００の当接部３０５の平面から板バネ４０１の底面までの高さＷ４よりわずかに短く形成されている。第１固定部５０２、第２固定部５０３、第３固定部５０４はいずれも下方が半径小となる逆円錐台形状に形成されている。   As shown in FIG. 3, the fixing pin 500 has a tip 501 at one end, and a second fixing portion 503 and a third fixing portion 504 that are protrusions for fixing to the conveyance guide 202 at the other end. It has been. The tip 501 has a hemispherical tip, followed by a first fixing portion 502 for engaging with the photoelectric sensor 300 in an inverted truncated cone shape. A distance W2 from the first fixing portion 502 to the second fixing portion 503 is formed slightly shorter than a height W4 from the flat surface of the contact portion 305 of the photoelectric sensor 300 to the bottom surface of the leaf spring 401. The first fixing portion 502, the second fixing portion 503, and the third fixing portion 504 are all formed in an inverted truncated cone shape having a lower radius.

図４に示すように、搬送ガイド２０２には光電センサ３００のセンシング部３０２と略同形状を有するセンサ孔２０３と固定ピンを挿入する固定ピン孔２０４が設けられている。第３固定部５０４の傾斜角Ａ１と固定ピン孔２０４の傾斜角Ａ２は等しくなるように設計されている。第２固定部５０３から第３固定部５０４までの距離Ｗ１は搬送ガイドの厚みＷ３より短く設計されている。   As shown in FIG. 4, the transport guide 202 is provided with a sensor hole 203 having substantially the same shape as the sensing portion 302 of the photoelectric sensor 300 and a fixing pin hole 204 into which a fixing pin is inserted. The inclination angle A1 of the third fixing portion 504 and the inclination angle A2 of the fixing pin hole 204 are designed to be equal. The distance W1 from the second fixing portion 503 to the third fixing portion 504 is designed to be shorter than the thickness W3 of the conveyance guide.

次に、光電センサ３００を搬送ガイド２０２に取り付ける手順について説明する。まず、図５（Ａ）に示すように、検出領域側ＤＳから反対側ＯＳへ向かって固定ピン５００を固定ピン孔２０４に挿入し、固定ピン５００を搬送ガイド２０２に固定する。この固定は、搬送ガイド２０２におけるすり鉢状の固定ピン孔２０４に、逆円錐台形状の第３固定部５０４がほぼ隙間無く当接し、かつ、搬送ガイド２０２の反対側の面に固定ピン５００の第２固定部５０３が当接することで実現される。言い換えれば、搬送ガイド２０２の固定ピン孔２０４周辺部が第３固定部５０４と第２固定部５０３で挟まれることによって搬送ガイド２０２への固定ピン５００の固定が実現される。   Next, a procedure for attaching the photoelectric sensor 300 to the conveyance guide 202 will be described. First, as shown in FIG. 5A, the fixing pin 500 is inserted into the fixing pin hole 204 from the detection region side DS toward the opposite OS, and the fixing pin 500 is fixed to the conveyance guide 202. In this fixing, the inverted frustoconical third fixing portion 504 is brought into contact with the mortar-shaped fixing pin hole 204 in the conveyance guide 202 with almost no gap, and the fixing pin 500 is fixed to the opposite surface of the conveyance guide 202. This is realized by the contact of the two fixing portions 503. In other words, the fixing pin 500 is fixed to the conveyance guide 202 by sandwiching the periphery of the fixing pin hole 204 of the conveyance guide 202 between the third fixing portion 504 and the second fixing portion 503.

その後、図５（Ｂ）に示すように固定ピン５００を光電センサ３００の固定ピン貫通孔３０１に挿入するようにして光電センサ３００を搬送ガイド２０２に近づけていき、センシング部３０２をセンサ孔２０３に挿入して取り付ける。このとき、板バネ４０１を検出領域側ＤＳへ向けて少し押し込み、固定ピン５００の第１固定部５０２を固定ピン貫通孔３０１から反対側ＯＳへ完全に突出させる。こうして光電センサ３００が搬送ガイド２０２に取り付けられた状態で、センシング部３０２の表面は搬送ガイド２０２の表面と同一平面上にある。また、固定ピン５００の検出領域側ＤＳに露出している露出部５０６は搬送ガイド２０２の検出領域側ＤＳの表面よりも低い位置にくる。図６に示すように固定ピン５００の第１固定部５０２と光電センサ３００の係合部４０２が係合する。   Thereafter, as shown in FIG. 5B, the fixing pin 500 is inserted into the fixing pin through hole 301 of the photoelectric sensor 300 so that the photoelectric sensor 300 is brought close to the transport guide 202, and the sensing unit 302 is moved to the sensor hole 203. Insert and install. At this time, the leaf spring 401 is slightly pushed toward the detection region side DS, and the first fixing portion 502 of the fixing pin 500 is completely projected from the fixing pin through hole 301 to the opposite OS. With the photoelectric sensor 300 thus attached to the conveyance guide 202, the surface of the sensing unit 302 is flush with the surface of the conveyance guide 202. In addition, the exposed portion 506 exposed on the detection region side DS of the fixed pin 500 comes to a position lower than the surface of the conveyance guide 202 on the detection region side DS. As shown in FIG. 6, the first fixing portion 502 of the fixing pin 500 and the engaging portion 402 of the photoelectric sensor 300 are engaged.

以上のような構成であるので、光電センサ３００を搬送ガイド２０２に固定するためのブラケットが不要となり、しかも、光電センサ３００の外側面に光電センサ３００自身を固定するための爪などの突起部も不要となり、その分の場所をとらないので、取り付け可能な範囲が広がる。特に近年小型化が望まれる現金自動預け払い機では、構造物間の空間が小さくなっているが、この小さい空間でも取り付けることができる。   Since it is the above structure, the bracket for fixing the photoelectric sensor 300 to the conveyance guide 202 becomes unnecessary, and also there is a protrusion such as a claw for fixing the photoelectric sensor 300 itself to the outer surface of the photoelectric sensor 300. It becomes unnecessary and does not take up that much space, so the range of attachment is expanded. In particular, in an automatic teller machine that is desired to be downsized in recent years, the space between structures is small, but it can be installed even in this small space.

また、光電センサ３００の底面に板バネ４０１が設けられており、しかも距離Ｗ２＜高さＷ４であるので、図５に示すように、光電センサ３００を搬送ガイド２０２に取り付けた状態において板バネ４０１が検出領域側ＤＳへ反っている。ゆえに、板バネ４０１の復元力により光電センサ３００と搬送ガイド２０２間および第３固定部５０４と搬送ガイド２０２間に接触圧が生じ、光電センサ３００を搬送ガイド２０２に安定して固定できる。   In addition, since the leaf spring 401 is provided on the bottom surface of the photoelectric sensor 300 and the distance W2 <height W4, the leaf spring 401 is attached in a state where the photoelectric sensor 300 is attached to the conveyance guide 202 as shown in FIG. Is warped to the detection region side DS. Therefore, contact pressure is generated between the photoelectric sensor 300 and the conveyance guide 202 and between the third fixing portion 504 and the conveyance guide 202 by the restoring force of the leaf spring 401, and the photoelectric sensor 300 can be stably fixed to the conveyance guide 202.

さらに、光電センサ３００の平面の中央部に短手方向のすべてが凹んでいる部分を有する凹部３０３が設けられているので、光電センサ３００と搬送ガイド２０２は離れた２ヶ所の当接部３０５で接する。もし、搬送ガイド２０２や光電センサ３００の当接部３０５が完全に平坦でない場合であっても、凹部３０３があることで光電センサ３００と搬送ガイド２０２は離れた２ヶ所で接することになるので、このような場合でも凹部３０３がない場合に比べより安定して固定できる。   In addition, since the concave portion 303 having a concave portion in the short side direction is provided at the center of the plane of the photoelectric sensor 300, the photoelectric sensor 300 and the conveyance guide 202 are separated by two contact portions 305. Touch. Even if the conveyance guide 202 and the contact portion 305 of the photoelectric sensor 300 are not completely flat, the photoelectric sensor 300 and the conveyance guide 202 come into contact with each other at two locations because of the recess 303. Even in such a case, it can be more stably fixed as compared with the case without the recess 303.

しかも、固定ピン５００に第２固定部５０３と第３固定部５０４が設けられており搬送ガイド２０２に固定ピン孔２０４が設けられているので、固定ピン５００を搬送ガイド２０２に固定してから光電センサ３００を固定ピン５００に固定させることができ、取り付けが容易にできる利点がある。すなわち、固定ピン５００と光電センサ３００を同時に操作して取り付ける必要がなく、１つずつ順に取り付けできる。   In addition, since the fixing pin 500 is provided with the second fixing portion 503 and the third fixing portion 504 and the conveyance guide 202 is provided with the fixing pin hole 204, the fixing pin 500 is fixed to the conveyance guide 202 and then the photoelectric pin is fixed. There is an advantage that the sensor 300 can be fixed to the fixing pin 500 and can be easily attached. That is, it is not necessary to operate the fixing pin 500 and the photoelectric sensor 300 at the same time and attach them one by one.

また、固定ピン５００を光電センサ３００の中央に１つ挿入するだけで固定する方式としたため、取り付け作業が容易であり、部品点数も少なくしてコストダウンを図ることができる。   In addition, since the fixing method is such that only one fixing pin 500 is inserted into the center of the photoelectric sensor 300, the attaching operation is easy, the number of parts can be reduced, and the cost can be reduced.

センシング部３０２の角部３０４は面取りされているので、紙幣がセンシング部３０２を通過する際の紙幣の引っ掛かりを防止できる。
なお、上述した実施例では、付勢手段を板バネ４０１としたがコイルバネとしてもよいし、光電センサ３００の当接部３０５は離れた２ヶ所に設けられているが２ヶ所以上設けてもよい。 Since the corner portion 304 of the sensing unit 302 is chamfered, it is possible to prevent the bill from being caught when the bill passes through the sensing unit 302.
In the above-described embodiment, the urging means is the leaf spring 401, but it may be a coil spring, or the contact portion 305 of the photoelectric sensor 300 is provided at two distant locations, but may be provided at two or more locations. .

この発明は、上述の実施形態の構成のみに限定されるものではなく、多くの実施の形態を得ることができる。   The present invention is not limited only to the configuration of the above-described embodiment, and many embodiments can be obtained.

この発明は現金自動預け払い機、複写機やプリンタなど紙葉類を搬送する機構を備える様々な機器に利用できる。   The present invention can be used for various devices including a mechanism for conveying paper sheets such as an automatic teller machine, a copying machine, and a printer.
