ABSTRACT:
A release locking device for use in photographic cameras of the type in which an exposure meter and electromagnetic actuating and releasing means for automatic exposure control are rendered operative in separate manner by their respective control or release switches as may be operatively associated with a display button and a shutter release button respectively. This device comprises a master switch connected between an electrical power source and a common input lead of these release switches to be closed and opened in response to an actuation and a release, respectively, of a manually operable member, thereby all of the release switches are rendered effective and ineffective at a time. In a preferred embodiment, this device is operatively associated with a shutter cocking mechanism to be actuable in automatic response to a protracting movement of the shutter cocking lever into an effective range of shutter cocking operation.
