業条件下で行うことができるという効果を奏する。As explained in detail above, the present invention provides a first light emitter.
a light-emitting unit attached to a second mounting plate; a light-receiving unit having a photoreceptor attached to a second mounting plate; Since the structure is equipped with a positioning member to align the optical axes of the light emitter and the light receiver and keep the distance between them constant, the optical axis adjustment of the light emitter and the light receiver and the adjustment of these distances are performed outside the machine. In addition, each of the above adjustments can be easily performed using the positioning member, and even once installed inside the machine, it can be easily taken out of the machine, making it easy to replace parts and perform maintenance and inspection in the event of a breakdown. can be done extremely easily. Further, in the present invention, the light emitting unit is provided with a first roller that is close to the light emitting body and is rotatable in the conveying direction of paper sheets, and the second roller is provided in the light emitting unit similarly to the first roller. and when the units are assembled, the rollers are configured to sandwich paper sheets between each other via the conveyor belt, so at the location where overlapping paper sheets are detected, The waving phenomenon of the conveyor belt (conveyor belt vibration) is prevented, and as a result, paper sheets can always be detected at a predetermined position, the detection level is stable, and overlapping sheets can be detected accurately. There are effects such as being able to. In addition, a guide member is provided in each of the light emitting unit and the light receiving unit, and a sloped portion is provided so that the opposing distance between the two guide members is gradually narrowed, and furthermore, paper sheets guided by the sloped portion are guided by a pair of mutually parallel guides. Since the distance between the light emitting body and the light receiving body is maintained constant while guiding between the rails, paper sheets can be reliably guided to the detection position, and the distance between the opposing guide members can be adjusted. This has the effect that adjustments and other operations can be performed under favorable working conditions outside the machine, as well as maintenance work for the light emitter and photoreceptor.

出装置。1 In a detection device that optically detects whether or not paper sheets that are conveyed while being held one by one between a pair of conveyor belts overlap, a first guide attached to a first mounting plate is used. A light emitting unit in which a light emitter is attached within a member and a light receiving unit in which a light receiver is attached in a second guide member attached to a second mounting plate are opposed to each other with their optical axes aligned. A positioning member is provided between the light-emitting unit and the light-receiving unit to maintain a constant mutual interval therebetween, and the light-emitting unit is
A first roller that presses one of the pair of conveyor belts from the inside near the light emitter is rotatably provided, and a first roller that presses the other of the pair of conveyor belts from the inside near the photoreceptor is provided in the light receiving unit. 2 rollers are rotatably provided, and the first and second guide members include an inclined portion that guides the paper sheets by gradually narrowing the opposing interval toward the transport direction of the paper sheets, and a slope portion that guides the paper sheets. It is characterized by having a linear guide rail that positions the paper sheet in the direction in which the light emitting body and the light receiving body face each other from a position where the facing distance between the parts is the narrowest toward the front in the direction of movement of the paper sheet. This is a paper sheet stack feed detection device.
