    • A main control circuit for controlling a door open-close drive motor and a lamp illuminating the interior of a garage is disposed in a body of a door operation control apparatus, and an interface circuit for applying control command signals to the main control circuit is connected by two signal conductors to a control box mounted on the wall of the garage. Signal voltages of a plurality of levels can be generated from the control box to be transmitted to the interface circuit by way of the two signal conductors, and the interface circuit discriminates the level of one of the signal voltage transmitted by way of the two signal conductors to apply a control command signal for controlling a controlled object corresponding to the discriminated voltage level.

    • Disclosed is an exposure amount control device for a copying machine comprising an exposure amount control circuit for controlling an exposure amount by controlling light of the exposure lamp for illuminating an original document to be copied and a digital light control signal generator for supplying a digital light control signal of a variable duty factor to the exposure amount control circuit. The digital light control signal generator includes a light intensity increase/decrease setting circuit and an oscillator for generating an oscillation output of a variable oscillation period in accordance with a light intensity signal from the light intensity increase/decrease setting circuit. The oscillation output of the oscillator is converted to an on-off light signal, which is supplied to the exposure amount control circuit as the digital light control signal. Thus, the digital light control signal generator is perfectly electrically isolated from a primary power supply circuit of the exposure amount control circuit and a highly safe exposure amount control device with a stable control ability due to an on-off light signal is provided.
    • 公开了一种用于复印机的曝光量控制装置,包括:曝光量控制电路,用于通过控制用于照射要复印的原稿的曝光灯的光控制曝光量;以及数字光控制信号发生器,用于提供数字光控制 可变占空因数的信号到曝光量控制电路。 数字光控制信号发生器包括光强度增减设置电路和用于根据来自光强度增减设置电路的光强度信号产生可变振荡周期的振荡输出的振荡器。 振荡器的振荡输出被转换为开关光信号,该信号作为数字光控制信号提供给曝光量控制电路。 因此,数字光控制信号发生器与曝光量控制电路的主电源电路完全电隔离,并且提供了由于开 - 关光信号而具有稳定控制能力的高度安全的曝光量控制装置。
