An improved photographic mechanism for mechanically sensing and firing a percussive flashlamp device is actuatable and resetable by the camera body release or shutter actuator and without requiring additional setting force upon film winding. The flashlamp device includes a preenergized striker, and the mechanism includes a sensing and actuating member movable into a first distinct position in engagement with the striker to sense the condition of the flashlamp. To fire the lamp, the sensing and actuating member is rapidly moved to a second and striker-dislodging position by a hammer or driver. Movement of the sensing and actuating member to such first and second positions is effected by depression of the camera body release or shutter actuator, and return movement thereof effects both retraction of the member and resetting or positioning of the hammer or driver. The mechanism also may be provided with one or more lamps or other indicating means for presenting an output or signal indicative of the sensed condition of the flashlamp or position of the preenergized striker.
