摘要:
A device for releasing shutter hold particularly for a single lens reflex camera including a shutter hold release device having a release mechanism for releasing the shutter hold wherein the driving power for the release mechanism is charged into the release mechanism in operative engagement of the charge of mirror driving power in a mirror driving mechanism of the device.
摘要:
The disclosed camera ordinarily uses an electromagnetic release device. A supplemental mechanical release device is enabled only when the electromagnetic release device's battery is absent from the battery case. The release operation is then carried out by the mechanical release device.
摘要:
A camera capable of changing over between electromagnetic release and mechanical release and to which a motor drive unit is attachable, whereby when in the mechanical release position the use of the motor drive unit permits an automatic winding operation to be initiated in response to return of the release button after the exposure has been completed.
摘要:
A camera capable of changing its operational mode having an operation member for moving the diaphragm between the fully opened state and closed state comprises a lock mechanism for keeping the diaphragm in the fully opened state, the lock mechanism being released by a diaphragm closing operation of the operation member, with release of the lock mechanism being prevented when the camera is set in the shutter time preference mode.
摘要:
A mechanically controlled shutter with a latch for holding the closing curtain in a charged position arranged upon running off of the opening curtain to start operation which then terminates at running off of the closing curtain to control the shutter time, wherein there is provided a keeper for holding the closing curtain latch in the charged position independently of the closing curtain latch, whereby after actuation of a camera release operation and before the opening curtain runs off, the keeper is actuated to release out of holding connection with the closing curtain.
摘要:
A camera provided with a control member for changeover from the film winding to the film rewinding mode and an operating member for actuating the control member, wherein the operating member is made movable in a first direction followed by a second direction, whereby at the terminal end of movement of the operating member in the first direction, the operating member is rendered capable or actuating the changeover control member as it moves in the second direction.
摘要:
A light shading device for a camera in which a soft and elastic light shading curtain has a base part which is fixed on a flat support surface, in the region of the shutter running path. The free end of the shading curtain is brought into elastic contact with the shutter curtain by way of a step provided on the support, the step serving to incline the free end of the light shading curtain with respect to the support surface.
摘要:
The disclosed camera includes a viewfinder which displays a display member representing a preset aperture value in its view field, and is capable of operating in open aperture and stopped down aperture manual exposure modes as well as a shutter priority automatic exposure control mode. A retracting arrangement retracts the display member from the view field in response to a shift either to the stopped down or the shutter priority automatic exposure control mode.
摘要:
A fixing member having a screw part to be attached to the cable release mounting screw hole of a release button of a camera and a cover member made of an elastic material are unified into one body and are arranged to be attachable to and detachable from the cable release mounting part of the release button.
摘要:
In the disclosed camera system, a spring arrangement to drive an automatic exposure mechanism of a camera and a magnet arrangement to control starting and stopping of the AE mechanism of the camera are provided within an electric drive device, and the automatic exposure control of the camera is carried out by mounting the electric drive device on the camera. Facilities, when energized by a power supply, are set to supply driving power to a motor for cocking the shutter, and an arrangement supplies power from the power source to the magnet arrangement for actuating the magnet arrangement. The present invention eliminates disadvantages of prior camera systems, namely, inferior response characteristic of the magnet and erroneous operations by the release action, and a large number of connecting terminals.
