いの欠点を有していた。Conventional Structure and Problems Conventionally, as shown in FIG. 5, a light source section a and a light receiving section b are provided so that the light beam crosses the input port, and the cutter c is driven by a drive device depending on the amount of light reaching the light receiving section b. There was a shredder configured to control the However, in such a shredder, the light receiving part b receives the external light e, and there is a very high possibility that the shredder will malfunction. In other words, when external light e hits light receiving section b, if the thickness of the paper to be shredded is thin or the number of sheets is small, the amount of light from light source section a that light receiving section b receives will be This changes depending on the input of the paper, but it has the disadvantage that the light receiving section b receives external light that has passed through the paper, so shredding cannot be started.

ター駆動回路である。 In FIGS. 1 to 3, 1 is the shredder main body, 2 is the paper inlet formed above it,
A cutter 3 and a motor 5 for driving the cutter 3 via a speed reducer 4 are built inside, and a discharge port 6 for shredded paper is provided below the input port 2. The input port 2 also has a hood-shaped cylindrical part 9 to which a light source 7 such as a lamp and a light receiving part 8 composed of a photoelectric conversion element corresponding to the light source 7 are attached.
has. The light source 7 and the light receiving section 8 are located at a position 14 where an extension of a line passing from the upper end 12 of the input opening to the upper end 13 of the entrance of the cylindrical part 9 provided on the opposite input opening surface corresponds to the inside of the cylindrical part 9. It is installed in a position further back than the Further, a transparent or translucent cover 10 is provided at the input port of the cylindrical portion 9 so as to match the input port surface. Next, Fig. 4 shows the circuit configuration, and 11 indicates that when no paper to be shredded is input, the light from the light source 7 enters the light receiving section 8, and the light receiving section 8 is turned on, and as a result, the motor Control is performed to stop the rotation of 5.
Also, when paper is inserted, the paper blocks the light from the light receiving section 8 and turns it into an OFF state, which is detected by the control circuit.
This is a motor drive circuit that performs control to start the circuit of the motor 5.
なお、フード状筒状部９とカバー１０は一体で
あつてもよい。 Note that the hood-like cylindrical portion 9 and the cover 10 may be integrated.
上記構成において、光源７及び受光部８はフー

の異物の侵入、堆積による誤動作は発生しない。 In the above configuration, the light source 7 and the light receiving part 8 are located in the hood-shaped cylindrical part 9 at a position deeper than the input opening surface, so the light receiving part 8 receives only the light from the light source 7 without being affected by external light. can be detected, and normal light emission and reception can be performed at all times. Furthermore, since a cover 10 is provided in front of the light source 7 and the light receiving section 8, malfunctions due to the intrusion and accumulation of foreign matter such as shredded debris will not occur even if the light source 7 and the light receiving section 8 are installed in a recessed position. .
さらに、カバー１０に茶色あるいは黒色などの
着色を行ない、半透明にすれば、光源７以外から
の外光の進入は完全に防ぐことが可能となる。 Furthermore, if the cover 10 is colored brown or black to make it translucent, it is possible to completely prevent external light from entering from sources other than the light source 7.
