ABSTRACT:
A bellows camera having a housing movably connected with its lens mount by a scissor linkage has a shutter with a spring-loaded setting ring carried on the lens mount, the setting ring being mechanically coupled with a wind-up lever on the camera housing through a gear train whose gears are carried on the legs of a knee joint articulated to the housing and to the lens mount. The housing-side end of the gear train is connected with the wind-up lever through a lost-motion coupling and is provided with a detent holding the setting ring in its cocked position until disengaged by the shutter release.
