Claims

[Scope of claim for utility model registration] Aperture blades that can select two types of aperture rows, maximum aperture or minimum aperture, by on/off control of an aperture magnet device, and an aperture blade that moves in conjunction with pressing down on the shirt button. A leading blade that starts C, a trailing blade that travels behind the leading blade and cuts the aperture, and a trailing blade that inhibits the trailing blade from moving, but moves to the non-inhibited position in conjunction with the leading blade C travel. a first locking lever that is retracted to a position that inhibits travel of the trailing blade or a non-retaining position by on/off control of a speed magnet device;
and a locking lever A2 which is retracted to the non-inhibiting position in conjunction with the travel of the leading wing when it is in the inhibiting position, and while the second locking lever is in the non-inhibiting position in advance. The travel start timing of the trailing blade is controlled only by the first locking lever, and when the second locking lever is also in the inhibiting position, the timing is controlled by both the first and second locking levers. Two shutter speeds can be selected by controlling the start timing of the trailing blades, and the aperture magnet device and the speed magnet device can be turned on and off according to the brightness of the subject.
1. A digitally controlled camera shutter, characterized in that an appropriate exposure is obtained by controlling the off-state and appropriately combining the aperture aperture and shutter speed.
