摘要： An electric shutter device wherein an armature lever is attracted by an electromagnet by making a large current flow to the electromagnet only when the operation of a self-timer ends so that a normal exposure operation may be thereby started in order to minimize the power consumption during the operation of the electric self-timer. This electric shutter device is provided with a pair of shutter blades which are also diaphragm blades, a closing drive plate engageable with the armature lever to control the opening and closing of the shutter, an exposure time controlling circuit controlling the energizing time of the electromagnet to determine a proper exposure time, an exposure warning circuit and a flash controlling circuit.

摘要： A program type electric shutter wherein a shutter blade which is also a diaphragm blade and is made to be able to latch an exposure warning indicating device to be inoperative just before the beginning of the opening of the shutter blade and a diaphragm device which can open and close a window for a light receiving element are operatively connected with each other in order to prevent the mis-indication of the exposure warning indicating device. This electric shutter is provided with an electric self-timer device and a flash controlling circuit.

摘要： A lens shutter has a diaphragm blade, a shutter blade, and a motor with a rotor reciprocatingly turned between an initial position and a final position by a current applied to a coil, to move the diaphragm blade to stop at an aperture regulating position and the shutter blade between an aperture open position and an aperture close position in cooperation with a first forcing member urging the diaphragm blade toward the aperture regulating position, a stopper for keeping the diaphragm blade at the aperture regulating position and a second forcing member urging the rotor against movement for the final position at least after the diaphragm blade abuts on the stopper. A magnetic device is provided to keep the rotor at positions where the aperture is fully opened and closed, respectively, even when the current to the coil is interrupted.
摘要翻译：透镜快门具有光阑叶片，快门叶片和电动机，其具有通过施加到线圈的电流在初始位置和最终位置之间往复转动的转子，以使光阑叶片移动到孔径调节位置，并且与将第一强制构件推动光阑叶片朝向孔径调节位置协作的孔径打开位置和孔关闭位置之间的快门叶片，用于将光阑叶片保持在孔径调节位置的止动器和用于将转子抵抗至少在隔膜叶片抵接在止动器上之后，最终位置的运动。提供一种磁性装置，即使当线圈的电流被中断时，分别将转子保持在开口完全打开和关闭的位置。
