しまうという問題点があつた。(B) Prior Art A series of pencil sharpeners that use a battery as a power source to drive a motor, rotate a cutter unit by the motor, and cut a pencil using the cutter unit are known as the Utility Model No. 58-136400, for example. There is a publication. To briefly explain the configuration of such conventional technology,
A cutter unit is rotatably provided inside the main body, a motor and a battery are housed, and the rotational drive of the motor is transmitted to the cutter unit by a reduction gear, and the rotating cutter unit cuts the pencil inserted from the pencil insertion slot. This is what we do. In this example, the portion surrounded by the rotating portion of the cutter unit becomes a dead space, and the volume of the cutting waste storage portion formed on one side of the main body is reduced. Also, due to the rotation of the cutter unit, a small gap is formed between the side wall of the cutting waste storage section and the cutter unit, but if too much cutting waste accumulates, the cutting waste will enter this gap and the cutter unit will lock. There was a problem that the rotation would stop.

The purpose is to provide a cutting tool.

も奏するものである。(g) Effects of the invention As explained above, the present invention provides a pencil sharpener in which a motor, a battery, a gear, and a cutter unit are housed in an outer case, and the cutter unit is rotated by the drive of the motor. An inner frame body that rotates in conjunction with the cutter unit is provided inside the case, a cutting waste storage section is provided between the inner frame body and the cutter unit, and a motor is disposed inside the inner frame body, and The drive shaft of the motor is fitted to a pinion gear that meshes with an internal gear disposed at the bottom, and an inner frame body that rotates in conjunction with the cutter unit is provided inside the outer shell case. Since the cutting waste storage section is provided between the inner frame and the cutter unit, a gap is not formed as in the conventional case, and the cutting waste moves together with the cutter unit, so even if a large amount of cutting waste accumulates in the storage section, there is no gap. The cutter unit does not lock and stop, making stable cutting possible at all times.In addition, the motor is placed inside the inner frame, and the pinion gear meshes with the internal gear located at the bottom of the case. Since the drive shaft of the motor is fitted, the outer shell case with the same storage volume can be used, compared to the case where the motor is not placed inside the inner frame as described in, for example, Japanese Utility Model Publication No. 37-10424. If so, the invention of the present invention allows the diameter of the internal gear to be made larger, and as a result, it is possible to obtain a larger reduction ratio and the cutting force can be increased.
