ABSTRACT:
The disclosed invention embodies a unique control for cocking and then releasing the shutter blades covering the lens structure of a photographic camera unit. The shutter blade operating mechanism is supported within a housing in which there are provided a pair of slotted regions through which extend control levers used to provide, when moved, the operational control needed to cock or release the blade structure relative to the photographic lens proper. Each control lever is provided at its end portion with a form of identification and conjoint means operable therewith and having a concordant form of identification so that through observation it may immediately be determined by an operator in which of two operational states the camera is instantaneously conditioned. Provisions are made for interlocking and coupling the controlling levers relative to each other, as well as to return each lever to its original position following a release. These indications which are used to provide representations of the operational states may be due to appropriately arranged color, shape, character indications, or similar identification of the instantaneous position of the control, thereby to insure that the operator will be placed in immediate awareness of the operation to be expected.
