摘要： A camera operable in shutter-priority automatic exposure mode comprises a photometric circuit, an exposure data memory circuit for storing information on a plurality of selectable diaphragm openings, and a control circuit for calculating a desirable diaphragm opening based on a shutter speed preset prior to an exposure and luminance data output from the photometric circuit, and determining an actual diaphragm opening based on a comparison between the calculated diaphragm opening and the selectable diaphragm openings. The control circuit checks whether the preset shutter speed is higher or lower than a predefined reference shutter speed and selects one of the selectable diaphragm openings that provides a higher shutter speed if the preset shutter speed is higher than the reference shutter speed, or selects one of the selectable diaphragm openings that provides a lower shutter speed if the preset shutter speed is lower than the reference shutter speed.

摘要： A camera shutter is capable of switching between a spring-drive mode and a motor-drive mode through a single electromagnet without performing an exposure operation. A control circuit controls a stepping motor for rotating a driving ring and the electromagnet for controlling the opening and closing operations of the diaphragm. A control circuit operates in a mode in which a first switch is turned ON, and in another mode in which a second switch is turned ON. When the first and second switches are turned ON, a normal photographing operation can be performed. However, when the first switch is turned ON and then OFF while keeping the second switch OFF, a power supply stop signal is transmitted to the electromagnet so that a closing sector is released from its restrained condition allowing the shutter to return to its initial state. When a photographer presses a shutter button after changing the mode, a photographing operation can be performed in the changed mode without the necessity of completing an exposure operation in the first selected mode.

摘要： A camera shutter includes a driving member rotated in forward and reverse directions by a motor and having first and second control portions. A switching circuit switches an operating starting position of the driving member between first and second positions. An opening member is controlled by the first control portion of the driving member and a first biasing member biases the opening member in the direction of opening the shutter. A first restraint member restrains an operation of the opening member and resists the bias of the first biasing member. A closing member is controlled by the second control portion of the driving member and a second biasing member biases the closing member in the direction of closing the shutter. A second restraint member restrains an operation of the closing member and resists the bias of the second biasing member. When the driving member starts its operation from the first position, the opening member is restrained by the first control portion of the driving member, and when the driving member starts its operation from the second position, the opening member is restrained by the first restraint member.

摘要： When a driving member is rotated counterclockwise by a single motor with a pair of sectors biased in the closing direction by a biasing spring, a first driving pin causes an operating lever to rotate clockwise. The pair of sectors pivot in opposite directions to each other in association with the driving lever to reach a first position where the sectors are fully open without overlapping the lens opening. When the driving member is rotated clockwise, a second driving pin also causes the operating lever to rotate clockwise. The pair of sectors pivot in opposite directions to each other to reach a second position, that is, a half-open position where an opening smaller than the lens opening is obtained. At this time, The second driving pin abuts on a part of one sector to restrain the displacement of the driving member. Accordingly, the driving member is prevented from overrunning, and no hunting occurs.

摘要： A camera shutter system has a motor driven sector for opening and closing a shutter opening. A photo-interruptor is positioned to intercept a light beam, to effect the sequential generation of first and second photo-interruptor signal pulses, the first pulse having a width that is a function of the speed of the sector. A timer has a counter that is set to a first count corresponding to an exposure value that is a function of the brightness of an object to be photographed and the width of the first photo-interruptor signal. The timer is controlled to count down in response to the second photo-interruptor signal, and the sector driving motor is energized during the count down of the timer.
