されている。Conventional Structures and Problems Generally, electric pencil sharpeners operate a motor using a countercurrent power source, and this motor drives a cutting mechanism to sharpen a pencil. When this pencil sharpener machine inserts a pencil into the pencil insertion slot, it detects the insertion of the pencil and turns on the power switch. However, the power switch is connected to the cutting mechanism due to its relationship with the member that detects the insertion of the pencil. In other words, it is located in the cutting mechanism chamber. A long lead wire drawn out from the motor section is connected to the power switch.
ところで、このような構成の電気鉛筆削り機において、
前記電気鉛筆削り機を落下あるいは衝隼を加えたときに
電源スィッチへのリード線がはずれ、これが金属部材に

から好ましくない。By the way, in an electric pencil sharpener with such a configuration,
When the electric pencil sharpener is dropped or subjected to an impact, the lead wire to the power switch may come off and come into direct contact with a metal member, or may come into contact with powder from the pencil lead, which is a conductor in the cutting chamber. This is undesirable from an electrical safety point of view, as it generates secondary electricity on the metal parts.

線によって電源回路に接続されている。In the figure, reference numeral 1 denotes a main body case made of synthetic resin, the interior of which is partitioned by an electrically insulating partition plate 2 to form a power supply chamber 3 and a cutting chamber 4. The motor 5 is placed inside the power supply room 3.
and a power switch 6. Further, the cutting chamber 4 is provided with a pencil insertion lower on the side thereof, and a cutter part 8 is provided in conjunction with the pencil insertion lower. The tip of a pencil insertion detector 9 made of an electrically insulating material is exposed to one side of the pencil insertion lower. This pencil insertion detector 9 is formed into a lever shape, and the other end is guided into the power supply chamber 3 through the partition plate 2 and is engaged with the actuator 6a of the power switch 6.
The tip portion is biased by a spring 1o so as to protrude into the pencil insertion opening Y. Although not shown, the power switch 6 is connected to the power supply circuit within the power supply room 3 through a short lead wire.
