本発明は、合成樹脂光伝送体を用いた光反射型用検知装
置に係り、特に分岐を有する合成樹脂光伝送体を用いた
光反射型用紙検知装置に関するものである。Detailed Description of the Invention [Industrial Application Field] The present invention relates to a light reflection type detection device using a synthetic resin light transmission body, and more particularly to a light reflection type detection device using a synthetic resin light transmission body having branches. This invention relates to a paper detection device.
［従来の技術１

障害となっている。電線束の太径化に対しては、電線の

号電線のＦ２Ｏ化あるいは各種検知類への光センサーの
適用が行われている。[Prior Art 1] As the functionality of OA equipment, AV equipment, etc. increases, the number of electric wires in the equipment increases and the diameter of the wire bundle increases, which poses an obstacle to miniaturization and weight reduction. Increasing the diameter of wire bundles has been addressed by reducing the diameter of the wires, but since the wiring is complicated and it is not possible to fully satisfy the need to make the equipment more compact, it is necessary to convert the signal wires inside the equipment to F2O. Alternatively, optical sensors are being applied to various detection types.

光伝送体を用いずに、発光及び受光素子のみで検知を行
う場合がほとんどである。An example of the above-mentioned optical sensor is paper detection inside a printer or a copying machine. There are two main types of detection methods: an interrupter type (lever type) that detects by turning the light on and off, and a light reflection type that detects by the difference in intensity of reflected light. In most cases, detection is performed using only the light-emitting and light-receiving elements without using the light-emitting and light-receiving elements.

とするため、組立ての合理化、経済性等で問題がある。[Problems to be Solved by the Invention] However, in this case, due to the detection position, it is difficult to centralize the electric wires used for the light emitting and light receiving elements, and at least one set of light emitting wires is required for one detection. Since a light-receiving element is required, there are problems with rationalization of assembly, economic efficiency, etc.
そこで、電線の集中化、素子の低減化（電線の削減化で
もある）を図る方法のひとつとして安価で取り扱い性に
優れた合成樹脂光伝送体の光センサの適用が検討されて
いる。Therefore, as a way to centralize electric wires and reduce the number of elements (which also means reducing the number of electric wires), the application of optical sensors made of synthetic resin light transmitters, which are inexpensive and easy to handle, is being considered.

ある。An object of the present invention is to provide a synthetic resin optical transmitter that eliminates the drawbacks of the prior art described above, reduces the number of light emitting elements and light receiving elements, and is capable of detecting paper in multiple directions with one synthetic resin optical transmitter. An object of the present invention is to provide a light reflection type paper detection device using the present invention.

This system detects the presence or absence of paper in the area to be inspected, the presence or absence of black bands, the conveyance status, the amount of remaining paper, etc. by using the difference in the A light-receiving element is arranged at one end of the transmission line, the other end faces each part to be inspected, and light from the light-emitting element is made to enter the emitting optical transmission line and is projected onto the part to be inspected from the other end,
By making the reflected light enter the other end of the receiving optical transmission path and detecting the intensity of the reflected light with a light receiving element, for example, the presence or absence of paper in the inspection section, the presence or absence of a black band, the conveyance state, the paper This allows the remaining amount to be detected.
この場合、発信用及び受信用光伝送路を分岐させること

a, and is projected onto the inspected part 8 from the other @7. In this case, when the inspected part 8 detects, for example, paper out, if paper is present, the light from the light emitting element 5 is reflected by the paper and enters the receiving optical transmission path 3b, and is transmitted to the light receiving element 6. The reflected light is detected, and it is determined from this whether there is paper present, and if there is no paper, the light from the light emitting element 5 is not reflected by the paper, so it does not substantially enter the receiving optical transmission path 3b, and therefore the light is not received. Since the element 6 does not detect reflected light, it is possible to determine whether the paper is out.
