スイツチが開閉不能になるという問題がある。Conventional structure and problems Generally speaking, the power switch of electric pencil sharpeners is automatically closed when a pencil is inserted into the pencil insertion slot of the main body of the electric pencil sharpener, and the power switch is automatically closed when the pencil is pulled out. The switch is set to open.
The opening/closing structure of this power switch is such that the power switch is placed around the pencil insertion slot, and an actuator is provided inside the pencil insertion slot that moves when the pencil is inserted or removed, and this mover opens and closes the power switch. , or when a pencil is pushed into the pencil insertion slot, the cutting mechanism at the rear is deflected rearward using the force of the pencil, and the power switch disposed at the rear of the cutting mechanism is closed. Some have been designed so that when the pencil is removed, the cutting mechanism returns to the front and the power switch is opened. However, in the former case where the power switch is located at the front of the main body, a long lead wire must be routed to the motor installed at the rear of the main body. In addition, the latter mechanism that moves the cutting mechanism back and forth has a problem in that shavings and the like adhere to the movement guide section, making it impossible to move smoothly, that is, the power switch cannot be opened or closed.

る。 In the figure, 1 is a main body case, a cutting mechanism section 2 (details not shown) is provided in the front part of the interior, and a rotation transmission member 3 such as a gear for rotating the cutting mechanism section 2 is provided in the middle part of the interior. A motor (not shown) is provided at the rear of the interior to serve as a driving source.
A power switch 4 for driving the motor is also provided. A front plate 6 having a pencil insertion opening 5 corresponding to the cutting mechanism 2 is provided at the front of the main body case 1. The pencil insertion opening 5
has an opening 8 on one side of its cylindrical portion 7. A switch operating body 9 is arranged inside the front plate 6. This switch operation body 9 is pivotally supported on the front plate 6 by a fulcrum member 10, and has a front lever 12 having a protrusion 11 inserted into an opening 8 on one side of the pencil insertion opening 5 on one side, and a front lever 12 on one side. It consists of a rod 13 that extends rearward from the pivot portion of the lever 12 and reaches the rear inside the main body case 1, and a rear lever 14 that projects laterally from the rod 13. The rear lever 14 has a cam portion 15. The cam portion 15 is brought into contact with the tip of the actuator 16 of the power switch 4. Further, the switch operation body 9 is biased by a spring 17 so that the protrusion 11 of the front lever 12 protrudes inward from the opening 8 of the pencil insertion slot 5, and a part of the rod 13 is attached to a member 18. rotation is maintained.
The power switch 4 has a contact portion 19 that opens and closes according to the displacement of the actuator 16, and is inserted into a circuit of a motor (not shown) to control the operation of the motor.

回転を停止する。 In the above configuration, when a pencil is inserted into the pencil insertion opening 5, the protrusion 11 of the front lever 12 of the switch operating body 9 is pushed outward by the pencil. Therefore, the front lever 12 rotates around the pivot, and this rotation is transmitted to the rear lever 14 via the rod 13.
can be conveyed to. This rear lever 14 performs the same movement as the front lever 12, and its cam portion 15
, the actuator 16 of the power switch 4 is pushed in, the contact portion 19 is closed, and the motor is driven. The cutting mechanism section 2 is rotated by the drive of the motor, and the pencil is sharpened. Next, when the pencil is pulled out, the front lever 12 of the switch operating body 9 is inserted into the pencil insertion opening 5.
is rotated back by the force of the spring 17, and the rear lever 14 is also rotated back accordingly. Then, the actuator 16 of the power switch 4 returns to its original position, and the contact portion 1
9 opens, the motor stops driving, and the rotation of the cutting mechanism section 2 is stopped.

である。 According to this configuration, since the power switch 4 is provided at the rear inside the main body case 1, the lead wires to the motor can be routed in short lengths, which not only simplifies the wiring, but also makes the wiring easier. Case 1
A means for detecting the insertion of a pencil in the pencil insertion slot 5 provided at the front of the camera and transmitting the detection to the power switch 4 is provided by means of the rotation of the switch operation body 9 consisting of the front lever 12, the rod 13, and the rear lever 14. Since the power switch 4 is opened and closed in a reliable manner, there is almost no influence from cutting debris and the like.
