Pencil sharpener

A pencil sharpener includes a frame, a drive mechanism, a transmission mechanism, a cutting mechanism, and a pencil-core adjustment mechanism. The pencil-core adjustment mechanism is constituted of a core stopper shaft, an elastic body, and a core adjustment switch constituted of electrode plates aligned in parallel. A pencil inserted into the cutting mechanism presses against and turns ON a switch provided in the drive mechanism to transmit power from the electric power supply unit to the drive device, thereby operating the cutting mechanism via the transmission mechanism to sharpen the pencil. When the pencil is pressed against the upper end of the core stopper shaft, a disk of the core stopper shaft contacts and pushes down one end of the longer electrode plate to separate the projection of the longer electrode plate from the shorter electrode plate, thereby turning OFF the core adjustment switch.
