Abstract
An apparatus for detecting the rotation of a motor for a camera comprises an encoder rotatable in synchronism with the driving of a motor for driving a driven portion in the camera, a photointerrupter for detecting slits formed in the encoder and outputting pulse signals, and a circuit board having disposed thereon a control element to which the pulse signals from the photointerrupter are input, the photointerrupter being installed on the circuit board.
