Abstract
A focusing adjusting device for a camera which uses the rotation of a motor shaft to move a photographing lens into focus includes an operating member which is movable to a number of positions. Each position of the operating member specifies a particular rotational direction and a particular rotational speed of the motor shaft. A detecting member is used for detecting the operating mode and the position of the operating member, and for generating detection signals in accordance with these detected parameters. Also provided is a rotation control circuit for receiving the detection signals and rotating the motor shaft at a direction and at a speed in accordance with the position and operating mode of the operating member.
