。Conventional Structure and Problems Conventionally, as shown in Fig. 5, a light source part a and a light receiving part A are provided so that the light beam crosses the input port, and depending on the amount of light reaching the light receiving part, the driving device of the cutter 〇 is changed. There was a shredder configured to control. However, in such a shredder, there is a very high possibility that the light receiving section receives the external light e and fails to receive it, resulting in malfunction. In other words, light reception! When external light e hits Isb, if the thickness of the paper to be shredded is thin or the number of sheets is small, the light meter from the light source section a that receives light from the light receiving section changes depending on the paper input. However, this method has a drawback in that the light receiving section receives external light that has passed through the paper, so shredding cannot begin.
発明の目的
本発明はこのような従来の欠点を解消したもので、受光

In the input port 2, there is a cylindrical part 9 shaped like a cylindrical part 9, which takes a light receiving part 8 consisting of a light source 7 such as a lamp and a photoelectric conversion element corresponding to the light source 7.
has. The light source 7 and the light receiving section 8 are located at a position that is an extension of a line from the upper end 12 of the input opening to the upper end 13 of the entrance of the cylindrical section 9 provided at the opposing input opening, or at a position that corresponds to the inside of the cylindrical section 9. It is installed in a position deeper than 14. A transparent or translucent cover 10 is provided at the inlet portion of the cylindrical part 9 so as to coincide with the inlet surface.

When the paper to be cut is not inserted, the light from the light source 7 enters the light receiving section 8, and the light receiving section 8 becomes ON state, and as a result, The motor controls the rotation of the motor 5 to stop, and when a piece of paper is thrown in, the paper cuts off the light from the light receiving section 8 and turns it off, which is detected by the control circuit and controlled to start the circuit of the motor 5. -1 drive circuit.

い。In the above configuration, the light source 7 and the light receiving section 8 are located in the hood-shaped cylindrical section 9 at a position deeper than the input opening surface.
The light receiving section 8 detects only the light from the light source 7 without being affected by external light, and can always perform normal light emission and reception. Furthermore, since a cover 10 is provided on the front of the light receiving section 8, even if the light source 7 and the light receiving section 8 are installed in a recessed position, malfunctions may occur due to the intrusion or accumulation of foreign matter such as debris. do not.
