Abstract
A motor drive which is adapted to be used with a camera having a mechanical shutter release mechanism is modified to enable the motor drive to be mounted in a camera having an electromagnetic shutter release mechanism, by providing a circuit which produces an electromagnetic release signal. The likelihood of blurring which may be caused by the rotation of a motor during the exposure of a film and which may be caused by the mere provision of the circuit for producing an electromagnetic release signal is avoided by preventing the rotation of the motor during the exposure of the film. In addition, difficulties are also avoided which are experienced when a film, not subject to any winding operation, is loaded into the camera.
