PROBLEM TO BE SOLVED: To provide a compact and low-cost air discharge device for driving an air pump by a one-way rotation of a motor wherein an excessive load is not applied to a motor shaft. SOLUTION: A crank disk 81 is rotated by a timing belt which is not illustrated in the figure from the motor 110. A crank lever 86 is pivoted for a crank disc 81 and a piston 55 is reciprocated in a cylinder 53 in a right-and-left direction of the figure as the crank disc 81 rotates. A filler 82 is arranged to project on the crank disk 81 and a sensor 95 for detecting the filler 82 is arranged. The filler 82 is detected by the sensor 95 when a driving signal is input to the motor and the crank disk 81 rotates once and thus the motor 110 is stopped. Hence, rotation and stop can be repeated without a clutch by the one-way rotation of the motor 110. COPYRIGHT: (C)2011,JPO&INPIT |
