摘要： In the disclosed device, forward and reverse rotation of a motor is used to wind and rewind a camera. A first semi-conductor switching element becomes conductive during winding and a second semi-conductor switching element becomes conductive during rewinding, the switching elements being connected in series across a power source. A selector switch has its fixed terminals connected to opposite poles of the power source. The motor is connected between the armature of the selector switch and the point between the switching elements. Driving circuits operate the switches so that the motor is driven in one direction when the selector switch is in one position and the reverse direction when the selector switch is in the other position and arranged to brake the motor after rewinding has stopped.

摘要： An electric motor drive device for a camera is arranged such that, in cases where power supply to a film winding motor is stopped with the camera still in an incomplete winding state and when the film comes to the end thereof after completion of a photographic operation on every frame, the power supply to the motor is resumed in response to a film rewinding completion signal produced from a film detection switch upon completion of film rewinding so that the camera can be brought into a winding completion state. This arrangement solves the problem of phase discrepancy arising between the camera body and the electric motor drive device when they are separated from each other.

摘要： A film advance error detection system for synchronizing the operation of shutter cocking and film winding mechanisms with a motor drive unit therefor. This system utilizes three transducers positioned adjacent the sprocket wheel, film perforations and rewinding spindle to pick up signals whose frequencies are related to their speeds. By processing the signals in combination with an output signal of a phase difference compensator, it is made possible to provide, in a selective manner, a display representative of the film advane error and reeling end in the winding and rewinding operations along with the automatic stoppage of rotation of the motor.

摘要： The disclosed device winds film in a continuous rapid-sequence mode or a non-continuous single-frame mode. A disengagement arrangement responds to a winding completion signal after each frame is wound in the continuous mode and disengages the transmission during the subsequent shutter release, but allows the transmission to remain engaged in the non-continuous mode and at the end of a winding sequence in the continuous mode. According to one embodiment, the disengagement arrangement contains an electromagnet that also actuates the camera's shutter release in the continuous mode.
