Abstract: A cutting apparatus includes a motor, a gear set, a gliding block, a rotating shaft and a handling element. The gear set includes a first gear part connected to the motor and a second gear part connected to a protrusion member. The center line of the protrusion member is shifted from the center line of the second gear part. The gliding block includes a gliding channel for receiving the protrusion member therein. The protrusion member is linearly moved along the gliding channel back and forth when the protrusion member is rotated in a circular motion. The rotating shaft is connected to an end of the gliding block such that the rotating shaft is rotated with synchronous linear movement of the protrusion member. The handling element has a first end sheathed around the rotating shaft and a second end operated to have the cutting member linearly moved along two guiding tracks.
Abstract: A computer peripheral input device includes a signal receiver for wirelessly receiving an input remote signal for a computer, a signal transmitter for wirelessly transmitting an output remote signal from the computer, a signal processing circuit electrically connected to the signal receiver and the signal transmitter for providing the computer with a signal in response to the input remote signal received by the signal receiver and providing the output remote signal for the signal transmitter in response to a signal generated from the computer, and a peripheral input circuit electrically connected to the computer for providing a computer peripheral input signal for the computer.
