摘要： PURPOSE:To prevent the titled device from the generation of a miss due to day photographing using a stroboscope as auxiliary light by delaying the output time of a close control signal based on exposure data when the aperture of a lens is so small as to photograph at the emitting of the stroboscope. CONSTITUTION:When the maximum aperture of the lens is Fm and the aperture of the lens is Fs, the step difference Fs-Fm of the lens aperture which is calculated by a step difference arithmetic circuit 13a based on exposure data and opening data is inputted to a correcting value determining circuit 13b and converted into a time signal proportional to the stop difference Fs-Fm and the time signal is inputted to the 1st time constant circuit 4. The circuit 4 delays an output time T3 of an aperture close control signal determined by exposure data obtained from an exposure arithmetic circuit 2 by a correction value DELTAT determined by the step difference Fs-Fm. A sector is transferred to a closing process at a time T4 delayed from the time T3 determined from the guide number of the stroboscope found out by an aperture value arithmetic circuit 7 only by a correcting value DELTAT. Consequently, the aperture of a shutter is increased and the aperture appropriate for stroboscopic photographing is formed to obtain exposure proper to a main object.

摘要： PURPOSE:To prevent light from leaking in film rewinding operation by providing a control means which controls a driving means so that it operates according to the detection outputs of the 1st and the 2nd detecting means. CONSTITUTION:When a film is rewound, a sprocket gear 5 is disconnected from the 1st intermediate train wheel 3 by the pushing-in operation of the film and a rewind button switch SW2 turns on at the same time. In this state, a charge detection SW3 is ON because a charge plate 9 is in the middle of movement to left, so a rewinding circuit which detects both switches SW2 and SW3 being ON further runs the charge plate 9 to left to charge a shutter. When the shutter is charged completely, a succeeding gear 14 disengaged from a segmental gear 13 in the 2nd intermediate train wheel 12 begins to idle and a motor is powered off with the charge detection switch SW3 which turns off. Consequently, while the exposure of the film is suppressed securely, the film is rewound.

摘要： PURPOSE: To improve the precision of automatic focus adjustment by detecting a focusing signal in synchronism with the motion of an electromagnetic driving device and thus detecting the focusing signal synchronously with the motion of a ratchet claw eventually.
CONSTITUTION: The focusing signal outputted by a two-division sensor 8 is inputted by a microcomputer 15 in synchronism with pulses of a stepping motor 3 to decide that an image is in focus or out of focus. When the focusing signal is detected, an electromagnet turning-off signal is outputted to power off an electromagnet 6. A lock lever 7 which is released from being attracted by the electromagnet 6 swivels clockwise with the energizing force of a spring 7a and its claw 7c engages a lock tooth part 5a. The rotation of the stepping motor 3 is transmitted to a ratchet wheel 5 through a distance ring 2, so the electromagnet turning-off signal which synchronizes with the stepping motor 3 is sent out in synchronism with the motion of the lock tooth part 5a of the ratchet wheel 5. The claw 5c of the lock lever, therefore, enters an engagement state at the position of the determined phase of the lock tooth part 7a with any pulse all the time, so the engagement between the lock tooth part 5a and lock lever claw 7a is secured.

摘要翻译：目的：通过与电磁驱动装置的运动同步检测聚焦信号，从而最终与棘爪的运动同步地检测聚焦信号，从而提高自动对焦调整的精度。构成：由分割传感器8输出的聚焦信号由微型计算机15与步进电机3的脉冲同步输入，以决定图像是聚焦还是聚焦。当检测到聚焦信号时，输出电磁铁关闭信号以使电磁体6断电。由电磁体6吸引而释放的锁定杆7以弹簧7a及其爪7c的作用力顺时针旋转与锁定齿部5a接合。步进电动机3的旋转通过距离环2传递到棘轮5，因此与步进电动机3同步的电磁铁关闭信号被同步地发送出来，与锁定齿5的移动相同棘轮5.因此，锁定杆的爪5c始终以任何脉冲在锁定齿部7a的确定的相位的位置处进入接合状态，因此锁定齿部5a和锁定杆爪7a被固定。

摘要： PURPOSE:To simplify structure and to improve the precision of exposure control by providing two sector blades rotatably to a lens aperture and driving them by a stepping motor which is controlled by an exposure program. CONSTITUTION:A CPU 8 receives a signal from a subject brightness measuring circuit 12 and accesses a data storage ROM 13 for automatic iris operation and a data storage ROM 14 for shutter operation. The ROM 13 is stored with an optimum aperture for subject brightness as data and the ROM 14 is stored with the optimum quantity of exposure for the subject rightness. A stepping motor driving circuit 15 outputs driving pulses for rotating the stepping motor on the basis of the data read out of the ROMs 13 and 14. Then, still picture photography and motion picture photography are brought under programmed control according to the subject brightness. Thus, the exposure control is carried out precisely by the simple structure.

摘要： PURPOSE:To decide whether a light beam is absent or not when an object is at infinite or finite distance by receiving reflected light from the object by a two-divided photodetecting element and deciding on its level while performing zero detection. CONSTITUTION:When a light beam from a projecting element 1 is within a range l1 and its integral output B is lower the upper hysteresis limit of a refer ence level C, the output D of a level deciding comparator C2 is at a low level (Lo), a transistor TR3 is off, and a TR4 is on, thereby suppressing the output E of a zero detection comparator C1 to the Lo. Then, the beam enters a range of l2 and the integral output B exceeds the upper hysteresis limit, the TR3 turns on and the TR4 turns off to release the suppression, so that the result of the comparator C1 is outputted as an output E. Then, when the light beam further moves and the integral output B coincides with the reference level G, the output E of the comparator Ca is inverted from the Lo to a high level (Hi). Then, the output F of an OR circuit OR goes up to the Hi and the Q terminal of an FF 1 is held at the Lo, turning off an electromagnet 23.

摘要： PURPOSE: To shorten exposure of a short second time, and also to obtain a fine- grained exposure step by switching forcibly the turning direction of a step- motor at an exposure time point corresponding to the brightness of an object to be photographed, and subdividing a part between the steps.
CONSTITUTION: A photographed object brightness measuring circuit 1 compresses logarithmically a current signal proportional to the brightness detected by a photodetector 1a and outputs a brightness signal. Also, a step-motor driving pulse generating circuit 5 is constituted of a reference clock generator 5a, a pulse train generator 5b for generating a two phase pulse for driving a step- motor 51 by frequency-dividing a clock signal from said generator. In a process in which the motor 51 turns continuously in the forward direction and opens a sector, an exposure quantity controlling circuit 2 executes an apex operation of film sensitivity and photographed object brightness by a differential amplifier 2a, and when the time corresponding to a difference of both of them elapses, an inversion signal is outputted from a timer 2d. As a result, a step-motor driving circuit 6 is inverted, the motor 51 is rotated backward forcibly and closes an optical path, and an optimum exposure to the photographed object brightness is ended.

摘要： PURPOSE: To simplify mechanism and to permit easy handling by driving all the operations for focusing and exposure adjustment by means of a single electromagnetic driving member.
CONSTITUTION: A stop motor 3 is turned and a driving plate 1 and an interlocking plate 2 are run toward the right when a release member is pushed down. An excited electromagnet 7e attracts simultaneously an electromagnet 7c and holds a focusing control lever 7 in the position where said lever does not contact with a detaining tooth part 2c. A light emitting element 6a irradiates impulsive light toward a subject at the arm end of a scanning lever 6. On the other hand, a bisected sensor 8 detects the impulsive light of the element 6a as the light reflected from the subject and outputs a focusing signal at the point of the time when the outputs from the two sensors coincide. The result of the measurement is displayed in a finder and the conduction of electricity to the electromagnet 7e is interrupted. The lever 7 released from the attraction is turned toward the right by the energizing force of the spring 7a to engage the claw 7d with the part 2c, thereby stopping the running of the plate 2. A distance ring 9 is further detained via a pin 2d to stop a photographing lens in the focusing position.
