MECHANISM FOR SYNCHRONIZING OPERATION OF A CAMERA SHUTTER AND A MECHANICALLY ACTUATED FLASH DEVICE

摘要

A member is positioned to act as a stop on shutter blade travel thus controlling camera exposure time. The member has a normal position and a flash position to which it is moved by the mounting of a flash device. In the flash position the member permits increased shutter travel thus increasing exposure time and it further acts as a linkage transmitting energy from the shutter blade to actuate a mechanically operable flash device.
