Abstract: A motor drive camera incorporates a motor drive device and a power source for the device and is adapted to mount a detachable auxiliary power source device to supply additional electric power to the motor drive device so as to raise the film winding up speed. The motor drive device includes a timer device whose operation is initiated at the same time as the initiation of power to the motor drive device and which effects the stop of power to the motor after the passage of a predetermined time. The operating time of the timer device is adapted to be changed in order to prevent the film from being damaged when mounting the auxiliary power source device to the camera.

Abstract: In the disclosed shutter, shutter blades are reciprocatable between exposure start positions and end positions. Reciprocative rotating electromagnetic drive sources with stators and rotors reciprocate the shutter blades. Magnetic members on the stator facing the rotors hold the latter at positions corresponding to the blades' start positions and are movable to vary the gaps formed between the rotors and themselves.

Abstract: A focal plane shutter device of the present invention is provided with leading blade braking means arranged near the terminal end of running down movement of the leading blades of the focal plane shutter to stop said leading blades in a standstill position either directly or through a member cooperative with the leading blades, and brake releasing means arranged in the trailing blades of the shutter upon termination of running down movement of the trailing blades to release the above-described leading blade braking means. Another feature is that the member cooperative with the leading blades in the standstill position and the braking member form a synchro-contact for use in flash photography.

Abstract: A slit exposure shutter having the front and rear screens thereof respectively arranged to be driven by a source of an electromagnetic driving force is provided with a minimum slit width insuring means which prevents uneven exposure resulting from difference in travelling speed between the front and rear shutter screens during a high speed shutter operation and particularly prevents a total absence of the slit, the shutter is also provided with a nullifying means which nullifies the insuring means when the shutter screens are on their return travels.

Abstract: A digital camera with five automatic exposure modes is provided with corresponding individual cards upon selective insertion into the camera to effect the operation of either or both of the shutter and diaphragm in accordance with the digital output of a computer through logic selection circuits as the mode information on the inserted card is read into a binary coded decimal counter controlling operation of the logic circuits. When the card is absent from the camera, a first controlling push button for sequential display of the modes is rendered effective to pass a pulse train to the counter so that upon release of the button, the current mode displayed can be set. The card further includes information relating to the determination of whether or not to give a sound warning signal which occurs, in one embodiment, when the film nears the terminal end of footage. In another embodiment, the buzzer is utilized to assist in releasing not only a first but also an additional three buttons for setting exposure factors and a number of film frames available just after a desired symbol or digital value appears in the display as they are sequentially presented.
