摘要: A drive ring drivable by a stepping motor is normally urged by a spring to turn in one direction around a lens aperture. When not in use, the stepping motor is not subjected to the resilient force from the spring since the drive ring is locked against rotation by a ratchet wheel engaged by an engagement lever. The stepping motor is therefore not subjected to undue stresses and is prevented from malfunctioning. Consequently, focusing failures and exposure adjustment failures which could otherwise arise from malfunctioning of the stepping motor are prevented from occurring. In operation, a solenoid is energized to move the engagement lever out of engagement with the ratchet wheel, which is then freed to allow the drive ring to be turned by the stepping motor.
摘要翻译: 由步进电机驱动的驱动环通常由弹簧推动以围绕透镜孔向一个方向转动。 当不使用时,步进电机不受弹簧的弹力,因为驱动环被接合杆啮合的棘轮锁定以防旋转。 因此,步进电机不会受到过大的应力,并且不会发生故障。 因此,防止由于步进电机故障引起的聚焦故障和曝光调整故障发生。 在操作中,螺线管被通电以将接合杆移动脱离与棘轮的接合,然后释放该棘轮,以允许驱动环由步进电机转动。

摘要: A camera shutter has an automatic focusing lens operative when actuated to effect an automatic focusing operation. An actuating ring is normally placed in a non-operating region and momentarily shifted to an operating region during the automatic focusing operation. The actuating ring is sequentially displaceable in forward and reverse direction through the operating region to actuate the automatic focusing lens, and displaceable in the forward and reverse directions in the non-operating region without effecting actuation of the automatic focusing lens. A ratchet mechanism is coupled to the actuating ring for selectively locking and unlocking the actuating ring in the non-operating region in response to the displacement thereof in the forward and reverse directions. A bi-directionally rotatable stepping motor is connected to drive the actuating ring to displace the same in the forward and reverse directions.

摘要: A program shutter has a plurality of shutter sectors driven in opening and closing directions by a reversible stepping motor to define a lens aperture during an exposure operation. An arithmetic circuit calculates an exposure amount corresponding to the brightness of the object being photographed, and a counting circuit outputs a pulse count corresponding to the number of steps through which the stepping motor should be rotated based on the calculated exposure amount. A pulse circuit produces driving pulses equal in number to the number of steps determined by the counting circuit, and a time circuit determines the ON/OFF periods of the driving pulses based on the calculated exposure amount. The driving pulses are applied to the stepping motor through a driving circuit to accordingly drive the shutter sectors in the opening and closing directions during the exposure operation.

摘要: A slip mechanism in the gear train of a clock comprises a gear wheel and an associated pinion coaxial with the gear. The gear wheel and pinion have interengaging surfaces for centering and rotatively guiding them relative to one another. A circle of resilient fingers on one of the gear wheel and pinions resiliently, frictionally and radially engage an annular friction surface of the other to provide a frictional coupling between them. Moreover hooks on the fingers retain the gear wheel and pinion in assembled relation to one another. In one embodiment the resilient fingers are integral with the pinion and are received in a concentric opening in the gear wheel of lesser diameter than a circle defined by the fingers in relaxed conditions. In another embodiment the resilient fingers are integral with the gear wheel and engage the outside of a concentric flange on the pinion of larger diameter than a circle defined by the fingers in relaxed condition. The pinion and gear can readily be formed of plastic material thus providing an inexpensive slip mechanism which can be easily assembled.
