<p>PURPOSE:To release locking by reversely rotating a motor which actuates a driving part in locking a stapler and display a locked state of the stapler. CONSTITUTION:A stapler controller 30 which judges an operation state of a stapler by using an output signal of a home sensor and a timer and outputs a motor reverse rotation command in a locked state, and a motor drive circuit 31 reversely drives the motor based on a motor reverse rotation command, are provided. When drive operation of a staple pin is started, a timer is started. Where a home position is not detected after a specific time has elaspsed, the stapler is judged to be in a locked state (abnormality), and the motor is reversely rotated. Where the home position is detected within a specific time when the motor is reversely rotated, the staple pin is judged not to be correctly driven (generation of jam) and where the home position can not be detected when a specific time has elapsed, a breakdown state of the stapler is judged. When the stapler is abnormal, the motor is stopped or electrification to the motor is cut, and its contents (jam, trouble) are displayed.</p> |
