Abstract
An automatic range finding and lens focusing module particularly adapted for attachment to the top edge of a pivotal shutter housing of a foldable camera. The module incorporates a complete assembly of accoustical, electronic, mechanical and electro-mechanical components necessary for system operation, such components being supported by a pair of parallel plates adapted for direct attachment to a shutter assembly modified only to provide mounting lugs and a coupling of a module output gear to a rotatable lens mount. The connection facilitates calibration of the module components with lens focusing movement.
