Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides the following advantages: 1- In an electric pencil sharpener using a metal base plate, an insulating plate is installed at the bottom of the motor chamber to insulate the entire base plate. Q, 1-Karu, and the above-mentioned 1! AI is used to prevent shavings from entering the remoter chamber.

- Crotch V'c The electric pencil sharpener has a partition i and a motor frame to form a cutting chamber and a motor chamber, and a front chamber (L front chamber) where the motor frame is connected and lN is the motor frame. ?I won't intrude.''
J. If the outer periphery is in close contact with the inner surface of the case and the base surface and exhibits the above-mentioned dustproof function, or if it is made of a base plate or metal plate, this base plate is deformed and the lower edge of the motor frame A gap is likely to form between the base plate 1, which is made of 11 pieces of gold plate 1, and increases the A degree.
e゛)l (Ni-mon gate length/-r1, 4 protruding strips;] Suka, this": Number the uni-mon ridge strips, make the ridge strips 1, and then make the base plate 1'11) 1) In the same way, a gap is created between the toe edge of the motor freno. Therefore, the shavings from the υ compartment enter the said gap, and the shavings from the jail core, which is particularly conductive, enter the motor conductor.
Propagates to the M part and produces small growths [, easily].

On the other hand, when the base plate is made of a metal plate, for example, if the main body of the electric pencil sharpener is dropped, the lead wires and other core parts of the motor may come into contact with the base plate V, causing an electric shock accident.

The present invention takes these conventional problems into consideration and aims at reliable dustproofing by utilizing an insulating plate in a motor room, and will be described below with reference to drawings showing 11 examples.

In FIG. 1C, it is a bottomless case body made of a 1:1 synthetic resin, and the inside of the case body 1 is partitioned by a vertical wall 2a of a motor frame 2 to form a cutting chamber 3 (!2 motor chamber 4). There is a cutter holder 6 in the cutting chamber 3.
The machine is equipped with a cutting mechanism such as a cutter 6, and a waste receiving box 7 is detachably provided.

A motor 8 is equipped in the motor chamber 4) L1 gear 9
