ABSTRACT:
A bellows camera has a housing movably connected with its lens mount by a ir of scissor links whose operation is controlled by respective rack members driven by pinions on a common shaft which traverses the housing and carries a focusing-control knob. If the knob is rotated beyond a limiting position of an operating range, corresponding to focusing on infinity, the rack members are decoupled from the scissor links and simultaneously unblock a spring-loaded latch (or a pair of such latches) which is then free to engage a peg on the lens mount upon manual collapsing of the camera. Restoration of the knob to the aforementioned limiting position releases the latch and allows the lens mount to be re-extended by hand or under spring pressure.
