ることを特徴とするカメラ用シャッタ機構。In a camera shutter having an electromagnetic device that starts exposure when excited and ends exposure when demagnetized, an exposure blade that can open and close an opening of the shutter, and an opening/closing member that opens and closes the exposure blade; an opening locking device having a locking portion with the opening/closing member and locking the opening of the exposure blade; an electromagnetic device connected to an electric control circuit that controls a predetermined exposure time; and the electromagnetic device is excited. It is composed of an iron piece member that is sometimes subjected to a suction operation, and a drive spring that is hung between the opening/closing member and the iron piece member to obtain the opening force and the closing force of the exposure blade, and the electromagnetic When the device is energized, the drive spring charges the opening force and closing force of the exposure blade due to its suction operation, and after the charging is completed, the opening lock of the exposure blade is released and the exposure blade is opened. When the electromagnetic device is demagnetized after a predetermined period of time has elapsed, the charged closing force acts, causing the iron piece member to separate and close the exposure blade together with the opening/closing member. A camera shutter mechanism characterized by:
