Abstract
A shutter dial releasable locking device for photographic cameras, includes a stationary circular guide member having a number of radially directed stepped portions, a stop member carried by the shutter dial and movable along the circumference of the guide member and biased to engage a stepped portion of the guide member, and a release member biased to project outwardly through a circumferential wall of the shutter dial and adapted to move the stop member in a radial direction of the shutter dial when pressed against a force which biases the release member. When the shutter dial is set in an automatic exposure control position, at a highest shutter speed of manual exposure control or in a mechanical exposure control position, the stop member engages a corresponding stepped portion of the guide member to hold the shutter dial in a position of the selected mode of shutter control.
