Abstract: First and second switch mechanisms are connected in series between means for generating an output voltage corresponding to detected light and means for storing that output voltage. The first switch is opened upon actuation of a shutter release member and the second switch is opened upon actuation of the reflex mirror from a viewing position to an exposure position. The diaphragm aperture is preset to a desired value and stopped-down from full aperture to that desired value prior to the initiation of film exposure such that the second switch is opened by the stopping-down of the diaphragm aperture in synchronization with the operation of the reflex mirror.

Abstract: An exchangeable lens barrel for use in a photographic camera is provided with a light sensitive element which, when the exchangeable lens barrel has been exactly fitted to the camera, receives the light which is reflected from the light sensitive film surface after it is transmitted through the objective lens and the iris aperture of the exchangeable lens barrel. A control system for an electronic flash tube in the camera or an electronic flash device fitted to the camera comprises a lighting control circuit and includes a timing circuit which controls the lighting of the electronic flash tube. The timing circuit is connected with the light sensitive element to generate a current which is integrated by the timing circuit, and the electronic flash tube is extinguished when the integrated voltage reaches a certain predetermined level, thereby the opening of the iris aperture in the exchangeable lens barrel is transmitted to the control circuit.

Abstract: Switching mechanism in an exposure control device for a photoconductive camera reduces unnecessary battery consumption by disconnecting the power source from a light measuring circuit and a mechanism for actuating shutter closing during those times when either the output of the light measuring circuit and/or the actuation of the shutter are not required. Manually operative individual switches respectively interconnect the light measuring circuit and the shutter actuation mechanism with the power source. A button switch movable between first and second positions engages with a locking member to prevent actuation of the shutter release button to prevent interconnection of the shutter actuating mechanism with the power source when an exposure time setting member is set to an automatic exposure position and the button switch is in the first position for opening the switch interconnecting the light measuring circuit with the battery source. Rotation of the exposure time setting member to any one of a number of positions rotates the locking member enabling the release button to be depressed and the interconnection of the shutter actuating mechanism with the battery source.

Abstract: An exposure control circuit is caused to store a voltage representative of the light intensity of a selected principal object within the object field to be photographed by a manually operated member which disconnects a photosensitive element from a capacitive storage element. Operation of the manual member causes a switch interconnecting the photosensitive element with the capacitive storage element to be opened and a restraining member is provided for maintaining the switch in an opened condition until an exposure has been terminated. A cocking member operated in conjunction with the cocking of the camera causes the switch to be closed in preparation for another photograph.

Abstract: In a still camera having a motor for advancing a film, the motor is actuated by means of a trigger-signal which is to be produced after an adjusted delay time after deenergization of an electromagnet for holding a previously opened shutter in the open state to the start of rotation of the motor. By adjusting the pause time appropriately, the film starts advancing without redundant delay, thereby enabling the efficient consecutive taking of many pictures over a predetermined period of time.
