摘要:
A movement control device has a DC motor by which a recording medium is moved by one frame of 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 an 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 the forward direction, the rotatable arm is rotated in a first direction, and thus the transmitting gear is meshed with the driven gear at a first point. When the stepping motor is rotated in the reverse direction, the rotatable arm is rotated in a second direction reverse to the first direction, and thus the transmitting gear is meshed with the driven gear at a second point different from the first point.
