摘要：A mechanism for flash attachment cameras, which when the shutter speed tting means is t at a position for flashbulb operation, moves a switch out of the path of movement of a lock means to permit the latter, upon depression of the shutter relea button, to lock a rotary member, such as an escapement wheel, operatively connected to the shutter closing thus holding the shutter open during flashbulb operation. When the shutter speed tting means is t at a position other than that for flashbulb operation, the switch is moved into the path of movement of the lock means to prevent the latter from locking the rotary member. Resilient means is provided between the lock means and the shutter relea button to permit the latter to be operated while the former is in its inoperative condition.夜晚的星
