摘要: A motor driven photographing control circuit for a double preference type automatic exposure control camera which is used for continuous photographing with a motor drive device attached thereto. When a sum of the shutter time computed by a shutter time computing circuit and the length of time required for a winding operation become longer than a preset photographing cycle in carrying out such continuous photographing, an alarm is displayed giving a warning that photographing in the preset cycle is not possible. Concurrently with this, a stop preference mode of photographing is shifted to a shutter preference mode and the shutter is controlled to be operated at a preset length of time, so that continuous photographing can be accomplished in a set cycle.

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: In the exposure control system disclosed, a first photoelectric element responds to light from a scene to be photographed. A second photoelectric element is a spot sensor set to respond from a portion of the scene to be photographed. An exposure control circuit which is coupled to the first and second photoelectric elements controls the shutter and aperture on the basis of at least the relationship between the responses of the first and second photoelectric elements.

摘要: A flash photographic exposure control system for a camera having an electrically timed shutter is provided with an additional electronic or mechanical timing device in combination with an electronic changeover switch responsive to attainment of the threshold level of the flash unit associated therewith. This is done to switch the camera from an automatic daylight exposure range to an automatic flash exposure range in which a particular timed interval suited for flash photography is made by the timing device which is brought into cooperation with the shutter operating means when the changeover switch is actuated, while the intrinsic timing device for the shutter being cut off from the control means for the shutter.

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: The present invention relates to the flash photographic system for camera which is characterized in that the system presents a safety device for preventing various misoperations generally apt to take place at the time of taking a photograph by using a flash light device. By means of the operation of this device, the shutter time is set at a certain determined time for taking a photograph under flash light with the shutter time setting means at the camera side whereby the flash light photographic mode setting signal can be obtained only when the light device is set at the state ready for flash lighting in such a manner that the camera is capable of taking a photograph under flash light only when this signal is obtained. According to a preferred embodiment in accordance with the present invention, even when the release operation is carried out so that the above mentioned flash light photographic mode setting signal is not obtained, the flash light device does not operate by means of the effect of the safety device so that the camera is automatically set in the state for taking photography under ordinary day light.

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.
