摘要： A motorized drive device for a camera having a motor and a transmission system. The deceleration control of the motor is started when an object being driven arrives at a short distance from a prescribed stop position. The detection of a fall of the speed of the object to an abnormal low value is carried out during the deceleration control period and its preceding motor drive period by respective different processes from each other.

摘要： Disclosed are a technique that in the film feeding control of a camera, before the film is wound up, when the voltage of a battery circuit for supplying voltage to the camera is above a voltage level high enough to wind-up the film, a film winding operation is initiated, and, if this winding-up operation does not terminate normally, that the film has ended is determined and the film is rewound, and another technique that when the above-described voltage level is detected, a motor for the rewinding is used as the load of detecting the voltage level of the above-described battery circuit.

摘要： A multiple exposure device for a camera is arranged to permit one and the same frame portion of film to be exposed to light a plurality of times. In taking a multi-exposed photograph, the device displays a multi-exposure mode; permits a manual resetting operation on the multi-exposure mode for improved operability of the camera; and computes the degree of exposure to be effected at each step of the multiple exposure to ensure an appositely exposed state of the film frame on which the multiple exposure operation is performed.
