PURPOSE:To certainly fix the stop position of a motor, by simultaneously performing hunting processing to both paper new line and carrier driving motors after the rotary operation of the paper new line motor. CONSTITUTION:A control part 1 receives a borrow signal (d) being an interruption signal and performs the motor rising, rotating and stopping processings to a carrier-driving motor 10 and, after the above mentioned stopping processing, performs the rising, rotating and stopping processings to a paper new line motor 9 in the same way and, thereafter, simultaneously performs hunting processing to both motors 9, 10. Because hunting processing is simultaneously performed to two motors, processing capacity is enhanced as a whole. Because a large value almost same to that of the current at the rotary time of the motor is used as the value of the current at the time of hunting, the stop position of the motor is certainly fixed. |
