摘要： In the disclosed arrangement, an energy storage device such as a capacitor is discharged through a flash lamp. A sensing device produces a signal when the storage voltage is sufficient to fire the lamp. A switchover device normally permits the shutter and exposure aperture to be set for daylight operation, but automatically responds to the signal to switch the shutter speed and the exposure aperture to suitable values for flash operation.

摘要： The present invention relates to an aperture setting device for camera at the time of photographing under day light as well as under flashlight. The device presents an aperture setting ring rotatable from the range of photographing under daylight to that under flashlight, being switched over according to the then photographing conditions, an information setting means to be moved according to the set information for photographing under flashlight such as information of the distance and an aperture ring for setting aperture, whereby the aperture ring is moved in engagement with the aperture setting ring in case the aperture setting ring is set for the range of photographing under daylight while the aperture ring is moved in engagement with the information setting means in case the aperture setting ring is set for the range of photographing under flashlight. In this way the aperture is set for photographing under daylight as well as under flashlight.

摘要： An electrical film counter for a photographic camera is provided with a differentiating circuit responsive to a film winding operation for producing an output pulse. The number of output pulses from the differentiating circuit is counted by an UP-DOWN counter and is decoded by a decoder designed to drive an indicator which indicates the number of film frames advanced through the film gate of the camera.

摘要： A focal plane shutter unit for a camera has a dimension-stable framework which has a rear wall member provided with an exposure aperture and with a film guide channel defining a path of the film behind the exposure aperture and which has a front surface to which a support structure having means for receiving and holding a lens mount is fixedly secured so that a predetermined spatial relationship between the objective lens and the film plane is established with dimension-stability, though the internal and external camera housing sections are made from a dimension-unstable material such as plastic. The framework is further adapted to carry front and rear shutter curtains with respective drive means, front curtain actuating means, rear curtain actuating means, and shutter cocking means coupled to the film wind mechanism of the camera.

摘要： A photographic flash exposure control system for a camera associated with a flash device. In conformance with a preselected shutter interval, an effective exposure aperture of a diaphragm device is computed by a computing circuit of the system. The total flash energy available from the flash device is automatically controlled in accordance with the luminance of the subject being photographed, to thereby provide correct exposure for complex lighting situations.

摘要： A single lens reflex camera adjusted to a shutter preference exposure range in which responsive to the light sensor and preselected shutter speed, an Appex type computer derives an exposure value which is previously stored, and thereafter automatic adjustment of the diaphragm mechanism in accordance with the stored exposure value starts in substantial coincidence with the start of pivoting movement of the mirror from its viewing to non-viewing position which is followed by the operation of the shutter mechanism to thereby minimize the time interval between the time when the shutter button is depressed and the time at which the shutter is released from its cocked position.

摘要： A flash illumination device is removably mounted on the body of an accompanying camera. Electric adjusting means set the diaphragm of the camera. A signal system produces a signal corresponding to a prescribed diaphragm setting and transfers the signal through a shoe attached to the camera body or through other electric connecting means. When the flash illumination device is connected to the camera body, the signal system provides an electrical signal which causes the adjusting means automatically to set the diaphragm.

摘要： In the disclosed flash camera, a flash unit is movable between protruding and stowed positions, and a sensor senses whether a capacitor that flashes the unit is adequately charged. A switch and a control circuit enable the flash only when the unit is in the protruding position and the sensor simultaneously senses an adequate charge.
