制限用抵抗により制限したことを特徴とする電動
ホツチキス用モータ制御回路。 In an electric stapler that uses a DC motor as a drive source to form and drive straight staple material into a U-shape, the DC motor is connected to a series circuit of a current limiting resistor and a first transistor, starting the DC motor by directly connecting emitter-collector paths of a second transistor in series and turning on (conducting) the first transistor during a first predetermined period in response to a start signal; Furthermore, during a subsequent second predetermined period, the second transistor is turned on (conducted).
At the same time, the first transistor is turned off.
A motor control circuit for an electric stapler, characterized in that the starting current of the DC motor is limited by the current limiting resistor only during the first predetermined period by setting F (non-conducting).
