Abstract: A camera includes a movable mirror arranged to be movable between a finder-viewing position and an exposure-retracted position, a spring member for applying to the movable mirror a force which causes the movable mirror to move from the finder-viewing position to the exposure-retracted position, and a movement mechanism for causing the movable mirror to move. The movement mechanism is provided with a cam member arranged to be rotated by a drive source and a cam follower arranged in abutment with the cam member. During rotation of the cam follower in a first direction, the movement mechanism causes the movable mirror to move toward the exposure-retracted position by means of the urging force of the spring member and, during rotation of the cam follower in a second direction, causes the movable mirror to move toward the finder-viewing position against the urging force of the spring member.

Abstract: A camera comprises a data imprinting device which is arranged to imprint data on the surface of film from a front side of an optical axis and is disposed between an aperture and a spool in a position to overlap with a focal plane shutter unit in the optical axis direction; a rotary member which is arranged to be rotated following the movement of the film surface and is disposed between the aperture and the spool; and a control part which is arranged to control the action of the imprinting device by detecting the amount of rotation of the rotary member.

Abstract: A camera includes a flash mechanism, an exposure-preparatory operation mechanism, a motor, a clutch mechanism arranged to transmit an output of the motor to the flash mechanism during the time of operation of the motor in a first direction and to transmit the output of the motor to the exposure-preparatory operation mechanism during the time of operation of the motor in a second direction, a first detecting device for detecting an operational state of the flash mechanism, a second detecting device for detecting an operational state of the exposure-preparatory operation mechanism, and a controller for controlling driving of the motor in response to outputs from the first and second detecting devices.

Abstract: A camera that comprises a flash unit supported swingably between a down position and an up position, a first drive mechanism for supplying a drive force to move the flash unit in a specific direction, and a second drive mechanism for supplying a drive force to move the flash unit in the specific direction. The drive force of the second drive mechanism is controlled to be lower than that of the first drive mechanism by a control circuit.

Abstract: A camera comprises a main mirror which is arranged to guide the light of an object to be photographed to a viewfinder optical system and to be movable to and from its finder-viewing position and its exposure position; a sub-mirror which is arranged to guide the object light to a focus detecting device and to be movable to and from its focus detecting position and its exposure position; a spring member which is arranged to urge the sub-mirror; and a change-over mechanism which is arranged to change the urging direction of the spring member according to the moving position of the the main mirror and also to restrict the position of the sub-mirror when the sub-mirror is in the focus detecting position.
