PURPOSE:To attain efficient operation with less number of components and with a simple construction, by providing the 1st and the 2nd direction clutches and a pulse control circuit, and using one pulse motor in common use for an original feeding roll and a recording chart feeding roll, and also for copying. CONSTITUTION:The pulse motor 50 drives the original feeding rolls 9, 10 and the recording chart feeding roll 41 and is possible for forward and reverse rotation. Further, the 1st direction clutch 58 is inserted to a timing pulley 52 and inserted between the motor 50 and the original feeding roll 9, and is coupled only at the forward rotation of the motor 50. Further, the 2nd direction clutch 59 is inserted to the timing pulley 53 and inserted between the motor 50 and the recording chart feeding roll 41, and is coupled only at the reversing of the motor 50. Further, a motor control circuit 60 drives to forward/reverse the motor 50 based on various control signals. |
