摘要： An electric pencil sharpener includes a frame, a first motor, a first transmission mechanism driven by the first motor, and a continuing feeding mechanism. The feeding mechanism includes a roller, a feeding wheel rotatably mounted to the frame and driven by the first transmission mechanism, and a driving assembly. An end of the driving assembly is driven by the first transmission mechanism, and the other end of the driving assembly is connected to the roller. The roller defines a groove in a bottom thereof, for pencils falling through. The feeding wheel defines a plurality of receiving slots each for receiving a pencil. The roller is driven by the driving assembly to swing, when the groove of the roller aligns with one of the receiving slots of the roller. Thus, a pencil falls into the receiving slot.

摘要： An electric multi-pencil sharpener includes an entering pencil vase, a sending mechanism, a hustling mechanism, a sharpening mechanism, and an exit pencil vase. The entering pencil vase includes a pushing mechanism for pushing pencils. The hustling mechanism is for clamping pencils to take the pencils into or out of the sharpening mechanism. The sharpening mechanism is for sharpening the pencils. The exit pencil vase has an exit mechanism. The sending mechanism connects the pushing mechanism, the hustling mechanism, and the exit mechanism, to move the pencils from the pushing mechanism to the hustling mechanism and move the pencils sharpened by the sharpening mechanism to the exit mechanism.

摘要： 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.

摘要： An electric sharpener has a casing, an electric motor, and a flat cutting blade for turning by the motor. There is an aperture in the casing through which a pencil can be inserted for sharpening by the cutting blade. An activation sensor is included for detecting when a pencil has been inserted through the aperture to close the electrical circuit, and a deactivation sensor for detecting a sharpened tip of the pencil to open the electrical circuit, thereby stopping the motor. The deactivation sensor has an actuating part for engagement and movement by the tip and a contact part supported by the actuating part for concurrent movement to break electrical contact with a fixed contact in the electrical circuit.
