    摘要: A driving wheel is mounted on the output shaft of a step motor, and a driven wheel engaging with gear wheels on which pointers are set is driven by said driving wheel. The driving wheel and the drive wheel have respective peripheral portions effective to couple the driving wheel with the driven wheel to rotate the driven wheel as the driving wheel rotates of an angular interval of rotation, and for thereafter disengaging the driving member from the driven member.In order to fix the position of a pointer after the driving wheel has finished rotating the driven wheel, the reversal preventing mechanism acts on the said driven wheel or the driving wheel. The driving wheel is driven by a stepping motor having a rotor which intermittently rotates in one direction through a predetermined angular interval to a rest position. The driven wheel is in turn intermittently rotated by the driving wheel to intermittently change the position of the pointer.

    摘要: A polarized drive rotor having opposite polarity poles is rotatably arranged in the magnetic field developed by a coreless field coil and a polarized auxiliary rotor also having opposite polarity poles is arranged and magnetically coupled to the drive rotor so as to displace, the drive rotor through a preselected angle with respect to the direction of the magnetic field developed by the coreless field coil. An output is taken out of either one of the polarized rotors to drive a gear train and accordingly drive a clock hand. Electric drive circuitry applies a forward electric current to the field coil to rotationally advance the rotors and after the rotors stop and when a preselected time has passed since the energization of the coil, the rotors are rotated again in the same direction by applying a reverse electric current to the coil. In this way the clock hand can be driven stepwise at intervals of preselected constant time.

    摘要: To prevent temporary reduction of battery voltage when driving a shutter, an exposure control drive apparatus is provided with a boosting circuit for boosting a voltage of the battery and outputting a boosted voltage. A capacitor is charged by the boosted voltage for driving an actuator of an exposure control mechanism. A detecting circuit detects a current flowing in the boosting circuit and a control circuit controls operation of the boosting circuit in accordance with a magnitude of the detected value so that the boosting circuit is prevented from boosting the battery voltage when the detected current exceeds a predetermined level and is permitted to boost the battery voltage when the detected current is below the predetermined level. In this manner, the current flowing from the battery is prevented from exceeding a maximum level.

    摘要: A circuit for detecting back light comprises a time constant circuit including a capacitor selectively connectable in series with either a resistive element, or one of two CdS photoconductive elements used to measure the central and surrounding portions, respectively, of an object being photographed. Three switches separately conect the resistive element and the two photoconductive elements in series with the capacitor. A circuit generates pulses for a length of time governed by a time constant determined by the time constant circuit, and three separate counters store the pulses the number of which is determined by the time constant. An arithmetic circuit processes the pulses stored in the counters to determine the amount of back light present on the object.

    摘要: In a program shutter including a forwardly/reversely rotatable step motor for opening and closing a shutter blade to effect automatic exposure, a drive pulse number and an interpolation quantity are set in first and second counters. A step drive pulse is generated by the first counter to start opening the sectors. After a final pulse is generated, the second counter is started, and at the timing when the time corresponding to the interpolation quantity is elapsed, the step motor is reversely rotated thereby to fractionate a gap between steps and obtain a proper exposure quantity.

    摘要: A device for detecting coincident focusing points for use in the controlling of the focusing of an automatically focusable lens comprises a single array of light receiving transducers for converting the distribution of light intensity of an image applied thereon to a set of corresponding electrical signals. The image applied to the array is from a first optical path from an object through the lens and from a second optical path from the object. At least one shutter is provided for cutting off one of the optical paths to alternatively effect the application of light from the one optical path on to the array to produce a first set of signals and thereafter the light from either the other optical path or the sum of the two optical paths on to the array to produce a second set of signals. The first set of signals are processed to produce a third set of signals which correspond to the ratio of each signal therein with respect to another of the signals and the second set of signals is processed to obtain a fourth set of signals corresponding to the ratio of each signal with respect to another of the signals. The third and fourth sets of signals, for each transducer, are compared and a signal is produced when a favorable comparison is obtained.

    摘要: The cam type time detecting mechanism of an alarm clock has a time gear wheel, an alarm gear wheel and a detecting plate, all mounted on a shaft. A hole is formed on either the alarm gear wheel or the detecting plate and a projection is formed on the other. The detecting plate is movable on the shaft in the axial direction of the shaft. The time gear wheel and the detecting plate have guiding parts respectively so that the time gear wheel, in its normal rotation, continuously pushes and turns the detecting plate. At least one of the time gear wheel, the alarm gear wheel and the detecting plate has a cam for lifting up the detecting plate if the time gear wheel and the alarm gear wheel turn either in normal and reverse directions.
