Device for indicating the ready condition of an electronic flash device

摘要

An electronic photoflash flash device includes a case containing a photoflash network including an indicator member illuminated in the flash ready condition and transferable by a manually operable selector member from a retracted position fully housed in the case to an advance position projecting from a face of the case for wide visibility. The case is a camera body and the camera diaphragm aperture is controlled by the selector member position which also closes the network power switch when the indicator member is advanced. In one mechanism the indicator member is biased to an advanced position and the selector member is biased to a retracted position in which a member coupled thereto releasably locks the indicator member in its retracted position and when the indicator member is advanced it releasably locks the selector member in its advanced position. Alternatively the indicator member is movable with the selector member and is biased to its retracted position.
