A camera having a body, a sliding member, a shutter release, and a timer. The sliding member is mounted in the camera body. The sliding member has a shutter button arm and a shutter actuation arm. The sliding member is moveable from a first position to a second position by application of a force to the shutter button arm. The shutter release is disposed in the camera body and is movable from a stopped position to a released position. The shutter release is biased toward the released position. The timer has a delay counter and a linkage coupled to the delay counter for movement in synchronism with the delay counter, from a start configuration to an exposure configuration and to an end configuration. The linkage has a stop that engages the shutter release when the linkage is in the start configuration and the sliding member is in the second position. The stop is disengaged from the shutter release when the linkage is in the exposure configuration. The holdfast grips the sliding member when the sliding member is in the second position and the linkage is in one of the start and exposure configurations. The holdfast is released from the sliding member when the linkage is in the end configuration.

Camera having self timer dwell

A camera includes a camera body, a shutter release, a timer, and a timer release arm. The shutter release is disposed in the camera body and is movable from a stopped position to a released position. The shutter release is biased toward the released position. The mechanical timer includes: a spring, a winder, a gear train, an escapement, and a linkage. The winder is mechanically connected to the spring and is movable into a wound position to load the spring. The gear train includes input, output, and intermediate gear units. The input gear unit is driven by the spring. The intermediate gear unit is disposed in mechanical sequence between the input and output gear units. The intermediate gear unit has a lower mechanical advantage in the sequence, relative to the input and output gear units. The escapement is driven by the output gear unit. The linkage is coupled to the gear train for movement with the gear train between start an end configurations. The linkage has a stop disposed to arrest the shutter release when the linkage is in the start configuration and the shutter release is in the stopped position. The stop is free of the shutter release when the linkage is in the end configuration. The timer release arm is disposed in the camera body and is movable between first and second positions. The timer release arm stalls the intermediate gear unit when the linkage is in the start configuration and the timer release arm is in the first position. The timer release arm is displaced from the intermediate gear unit when the timer release arm is in the second position.

Camera and mechanical timer mechanism

A camera back comprising a light emitting device for recording information on a filmstrip in conjunction with picture-taking, and a film support for ensuring the shape of the filmstrip when information is recorded on the filmstrip, is characterized in that the film support has a plurality of parallel curved film ribs integral with the camera back for shaping the filmstrip in a curve, a recording opening is formed in the camera back adjacent one of the curved film ribs, and the light emitting device has a flat light emitting face positioned over the recording opening at an acute angle with respect to the one film rib.

Camera back

A camera structure includes a multiple function shutter button assembly that is capable of performing multiple functions in combination with other camera elements. More specifically, the camera includes a camera body, a circuit board attached to the camera body, a shutter button assembly including a sliding member movably coupled to the camera body, wherein the sliding member comprises a shutter button arm, a shutter actuation arm, and an electrical contact arm, and a biasing mechanism for biasing the sliding member to an initial position. The shutter actuation arm includes a shutter actuation member that activates a shutter release mechanism of the camera when a force is applied to the shutter button arm to move sliding member from the initial position to a shutter actuation position. The electrical contact arm includes electrical contact elements that come into contact with contact pads provided on the circuit board when the force is applied to the shutter button arm to move the sliding member from the initial position to an electrical contact position. The electrical contact arm can either be fixed in a stationary manner or coupled to the sliding member by a yoke assemble that permits movement of the electrical contact arm along an arc. A lens cover assembly is provided that is moveable from a closed position to an open position, wherein the lens cover assembly includes a slide plate having a retainer portion that slides over the electrical contact arm to maintain a contact pressure. The slide plate further comprises a shutter lock member that is positioned beneath the shutter actuation arm to prevent movement of the slide member to the shutter actuation position.

Multiple function shutter button assembly

A camera back comprising a film support for ensuring the shape of a filmstrip, is characterized in that the film support has a plurality of parallel film shaping ribs integral with the camera back, an opening for a battery is formed in the camera back to be located across at least some of the film ribs, and a door for closing the opening has integral rib-extensions that are longitudinally aligned with the film ribs across which the opening is located.

A camera having a body, a push-pull, a sliding member, a shutter release, and a timer. The push-pull is movable between primary and secondary positions. The sliding member has a shutter button arm, a shutter actuation arm, and a timer release arm. The sliding member is moveable from a first to a second position by depression of the shutter button arm. The sliding member is limited to movement from the first position to an offset position when the push-pull is moved from the primary to the secondary position. The sliding member in the offset position is substantially blocked from moving toward the second position. The shutter release is movable from an initial position to a stopped position and to a released position. The shutter release is detained in the initial position by the shutter actuation arm when the sliding member is in one of the first and offset positions. The shutter release is released from the shutter actuation arm when the sliding member is in the second position. The shutter release is biased toward the released position. The timer includes: a delay counter and a linkage coupled to the delay counter for movement, from a start configuration to an end configuration. The linkage has a stop that is disposed to arrest the shutter release and gear train when the linkage is in the start configuration and the shutter release is in the stopped position. The stop is free of the shutter release when the shutter release is in one of the initial and released positions. The timer release arm deactuates the timer when the sliding member is in the first position and actuates the timer when the sliding member is in one of the offset and second positions.
