    • An apparatus which includes a feeding device for feeding a document onto a document platen on which the document is irradiated by a light source to obtain a copy image and a discharging device for discharging the irradiated document from the document platen. The apparatus includes a housing unit shaped in the form of a plate for covering the document platen; a hinge for pivotally mounting the housing unit on the document platen, and first, second and third sub-housings made to protrude upwards from the top surface of the housing unit. The first sub-housing is disposed on one side of the housing unit and incorporates the feeding device. The second sub-housing is disposed on the opposite side to the one side and incorporates the discharging device. The third sub-housing is disposed on a side between the one side and the opposite side and incorporates both the hinge and driving mechanism for both the feeding device and the discharging device.

    • A light modulator module includes a submount; a semiconductor laser and a semiconductor light modulator having a signal input terminal integrated on the submount, the semiconductor laser outputting laser light and the semiconductor light modulator modulating the laser light in response to a high-frequency signal input to the signal input terminal; a strip line for transmitting the high-frequency signal, the strip line having first and second terminals, the second terminal receiving the high-frequency signal; a terminating resistor terminating the strip line and having opposed first and second ends with the second end being grounded; a first wire connecting the signal input terminal of the semiconductor light modulator to the first terminal of the strip line; and a second wire connecting the first end of the terminating resistor to the signal input terminal of the semiconductor light modulator. In this structure, the inductances of the first and second wires are present between the signal supply and the terminating resistor. When the frequency of the signal is increased, current flowing in the terminating resistor decreases, compensating for an increase in current flowing through the light modulator, whereby the frequency dependence of the total current is reduced. Deviation of impedance from a prescribed value and return loss are reduced.
    • 光调制器模块包括底座; 半导体激光器和半导体光调制器,其具有集成在所述基座上的信号输入端子,所述半导体激光器输出激光和所述半导体光调制器响应于输入到所述信号输入端子的高频信号而调制所述激光; 用于发送高频信号的带状线,带状线具有第一和第二端子,第二端子接收高频信号; 端接电阻终止带状线并且具有相对的第一端和第二端,其第二端接地; 将半导体光调制器的信号输入端子连接到带状线的第一端子的第一线; 以及将终端电阻的第一端连接到半导体光调制器的信号输入端的第二线。 在这种结构中,第一和第二导线的电感存在于信号电源和终端电阻之间。 当信号的频率增加时,流过终端电阻的电流减小,补偿流过光调制器的电流的增加,从而降低总电流的频率依赖性。 阻抗与规定值的偏差和回波损耗减小。
