摘要:
A movement control device has a DC motor by which a recording medium is moved by one frame of an image, and a stepping motor by which a recording medium is moved by a small predetermined amount. A driven gear fixed on the output shaft of the DC motor is meshed with a gear of a moving mechanism on which the recording medium is mounted. A clutch has a transmitting gear which is rotatably supported by a rotatable arm and can be meshed with the driven gear. The rotatable arm is rotated by the stepping motor. When the stepping motor is rotated in a forward direction, the rotatable arm is rotated in a first direction. Thus, the transmitting gear is meshed with the driven gear at a first point. When the stepping motor is rotated in a reverse direction, the rotable arm is rotated in a second direction reverse to the first direction. Thus, the transmitting gear is meshed with the driven gear at a second point different from the first point.
