Camera comprising an exposure release key

Claim 2

A camera having a housing, an objective, and a movable support for said objective, said support being attached to a tube, said tube carrying said support, said tube and said support being movable along the optical axis of the objective from a nonuse state of said camera to an operative state thereof, said camera comprising a slidable cover slide for protecting said objective in said state of nonuse of said camera, said cover slide being slidable in a plane at right angle to said optical axis from said nonuse state to said operative state of said camera, a slidable control slide movable in a plane at right angle to said optical axis; two guide cams disposed on said control slide; first and second means for moving said tube carrying said support and said cover slide, respectively; guide pin means on said first and second means, said pin means operatively engaging said guide cams, respectively; and said guide cams having section of different inclinations providing movements of said tube and of said cover slide in timed relationship relative to one another.

Claim 3

A camera according to claim 1, said support carried by said tube comprising resilient flanges and said guide pins being moulded from highly impact-resistant tough plastics.

Claim 4

A camera according to claim 1 further comprising a spring moving said control slide from a first position in which said camera is in said nonuse state to a second position in which said camera is in said operative state, resting means on said control slide, an exposure release key and a member connected with said exposure release key of said camera, said member engaging said resting means for locking said control slide in said state of nonuse of said camera.

Claim 5

A camera according to claim 3, said control slide comprising an operation key disposed for protruding outwardly of said housing of said camera in said operative state of said camera, said key disposed further for moving said control slide for returning said tube carrying said support of said objective to said nonuse state of said camera.

Claim 6

A camera according to claim 3, said first means consisting of a rocker, a pair of arms extending from said rocker, said arms engaging said tube, said pin means on said rocker disposed to engage one of said two guide cams of said control slide, the movement of said control slide being transmitted to said tube by said rocker operated by said one of said two guide cams and said pin means.

Claim 7

A camera according to claim 3, said second means consisting of a rocker arm pivotally mounted in said housing of said camera, said pin means on said rocker arm disposed for engaging the other one of said two guide cams on said control slide for transmitting the movement of said control slide to said rocker arm, connecting means on said rocker arm for connecting the latter operatively with said cover slide, and said sections of different inclinations on said other one of said guide cams providing for a first movement to release the opening for said tube and support of said objective and for a subsequent second movement of said tube and support itself while the position of said release of said opening as obtained by said first movement remains unchanged.

Claim 8

A camera according to claim 6, and a release rod pivotally connected with said exposure release key, said release rod having a free end, a pin on said free end, said conTrol slide having a substantially triangular opening, a fixed plate in said housing of said camera, said plate having a substantially U-shaped guide recess, said pin engaging said recess through said triangular opening, a spring on aid release rod for urging said release key into an open position, said U-shaped recess having an outer and an inner U-leg, said pin driven by said triangular opening being shifted by the movement of said control slide within said U-shaped recess for disengaging said release rod from the exposure release mechanism, engaging said outer U-leg for attaining a rest position, said pin being disposed for continuing the movement thereof in said outer U-leg upon actuation of said release key for releasing said control slide, operating said cover slide and said tube with said support, further moving through said U-shaped recess by one side of said triangular opening in said control slide into said inner U-leg for permitting exposure releases by said release key without changing positions of said control slide and of said tube with said support of said objective.
