制御装置。[Claims for Utility Model Registration] A zoom switch for switching to wide-angle or telephoto zooming, and a motor drive circuit for rotationally driving a zoom motor based on an ON signal of the zoom switch, the zoom motor being rotated by a selection operation of the zoom switch. In a zoom motor control device for a video camera that performs zooming by rotating forward and backward to move a zoom lens in a wide-angle direction or a telephoto direction, the rotation speed of the zoom motor is controlled between a constant speed or a constant speed. 1. A zoom motor control device for a video camera, comprising a speed change switch for setting one of variable speeds, and a variable zoom speed circuit for outputting a speed setting signal in response to operation of the speed change switch.
