PURPOSE:To execute time exposure at the time of underexposure, and to execute a photographing extending over a long period of time at a prescribed time interval by providing the first and the second stopper pins on positions corresponding to one rotation and half rotation positions of a shutter, and making them couple to a stop lever for stopping the shutter. CONSTITUTION:In a mechanism for executing feed and exposure of one frame of a film by one rotation of a shutter, when a motor 50 is driven, a shutter 52 and a winding intermediate shaft 54 are interlocked and start rotation. An electric contact is constituted between a conductive layer stuck to the surface of the winding intermediate shaft 54, and the first shutter contact 60, the second shutter contact 62, an inserting timing contact 64 and a ground common contact 66; a specified timing signal is generated, the first and the second stopper pins 74, 76 and a stop lever 72 are coupled, when a time exposure signal exists, the stop lever 72 is operated by the first timing signal, and it is coupled to the second stopper pin 76, by which the time exposure is executed. |
