Claims

[Claims for Utility Model Registration] (1) A blade holder having a conical hole and a flat blade along the generatrix of the conical hole is rotatably supported in the case, and A pencil sharpener characterized by having a rotating means for rotating a holder. (2) In paragraph 1 of the claims for utility model registration,
A pencil sharpener characterized in that the rotation means is comprised of a motor provided in the case, and a transmission mechanism that reduces rotation of the motor and transmits it to the blade holder. (3) In paragraph 2 of the claims for utility model registration,
The blade holder is rotatably and vertically movably supported by the case with the conical hole facing upward, and is further provided with a switch that drives the motor when the blade holder moves downward by a certain amount. Pencil sharpener. (4) In paragraph 3 of claims for utility model registration,
The switch is connected to a fixed contact fixed to the case, and a plate that is arranged opposite to the fixed contact and normally biases the blade holder upward, and is displaced toward the fixed contact by the downward movement of the blade holder. A pencil sharpener characterized by comprising a spring-like movable contact. (5) In paragraph 1 of the claims for utility model registration,
A pencil sharpener characterized in that the rotation means includes a handle, and a speed-up mechanism that increases the speed of the rotation of the handle and transmits the rotation to the blade holder. (6) In paragraph 5 of claims for utility model registration,
The speed increasing mechanism includes a pinion provided at the end of the counter-conical hole of the blade holder, an internal gear meshing with the pinion and rotatably provided in the case, and an eccentric position of the internal gear. A pencil sharpener comprising: a rotatable handle;
