A sub-miniature photographic camera with a housing elongated in a direction transverse to the optical axis, and having a lens window opening and a viewfinder window opening in the front edge of the housing, spaced from each other in the direction of elongation of the housing. A cover plate or blind plate is slidable within the housing from a position closing both openings to a position uncovering both openings. A manually operable member slidable on the housing in a direction transverse to the optical axis serves simultaneously to initiate movement of the cover plate to an open position, and to wind the film, and to tension or cock the shutter operating mechanism ready for making an exposure. After the film winding and shutter tensioning movement of the manually operable member, if the operator decides not to take a picture right away and therefore moves the manually operable member back to its initial position in order to move the cover plate to its closure position, the manually operable member becomes automatically disconnected from the film feeding parts, so that it will not cause further film feeding movement if the manually operable member is again moved in a film feeding direction in order to shift the cover plate to an open or picture-taking position, when the operator is ready to make an exposure.
A photographic camera having an optical axis and comprising a housing and a manually operable handle movable relative to said housing to and from a basic position in a direction transverse to said optical axis, said housing having at least one optical opening for passage of light, a cover plate operatively coupled to said handle for movement between a position covering said optical opening and a position clearing said opening, a shutter, means for releasing said shutter to make an exposure, film winding mechanism, a toothed rack movable for operating said film winding mechanism, an operative connection between said handle and said rack to operate said rack from movement of said handle, the means for automatically rendering said connection inoperative after said film winding mechanism has been operated and before said shutter has been released for the next exposure so that said handle and said cover plate may be freely moved without causing movement of said rock or operation of said film winding mechanism, until the next exposure is made.
A photographic camera having an optical axis and comprising a housing and a manually operable handle movable relative to said housing to and from a basic position in a direction transverse to said optical axis, said housing having at least one optical opening for passage of light, a cover plate operatively coupled to said handle for movement between a position covering said optical opening and a position clearing said opening, a shutter, means for shifting said shutter to a cocked position ready for an exposure, means for releasing said cocked shutter to make an exposure, film winding mechanism, feeler means for feeling the position of film in the camera, said feeler means having a first position allowing a film feeding movement and a second position blocking further film feeding movement after one picture area of unexposed film is placed in a film gate of the camera, a toothed rack movable for operating said film winding mechanism, an operative connection between said handle and said rack to operate said rack from movement of said handle, a device for disconnecting said rack from said handle, means normally holding said device in an inoperative position, and means responsive to said feeler means and said shutter shifting means for releasing said device holding means when said feeler means is in said second position and said shutter is cocked, said device being set in a position to disconnect said rack from said handle when said handle returns to said basic position, so that said handle may thereafter be moved without causing longitudinal movement of said rack.
