    • Disclosed is a multi-layer type light emitting device including: at least two light emitting sources disposed to be multi-layered; and an optical surface disposed so as to correspond to each of the light emitting sources excluding one positioned at the rearmost stage for forwardly reflecting rays of light emitted by the light emitting source and transmitting rays of light emitted by the light emitting source disposed at the rear stage. With this device, rays of light emitted by each of the light emitting sources excluding one positioned at the rearmost stage are reflected from the corresponding optical surface and radiated forwardly. In this case, when a different optical surface is disposed on the front stage, the rays of light transmit the optical surface and are radiated to the exterior. In the case where rays of light emitted by the light emitting source positioned on the rearmost stage are radiated forwardly, they transmit the optical surface positioned at the front stage and are radiated to the exterior. Accordingly, rays of light emitted by the multi-layered light emitting sources are radiated from the same plane to the exterior.

    • A lateral registration adjusting device for use in an optical writing system, such as a laser beam printer, is provided. When a sheet of recording paper has arrived at a registration roller which is driven to rotate intermittently in association with the rotation of a photosensitive drum, a discrepancy between the sheet of recording paper and a reference position in the lateral direction transverse to the direction of transportation of the sheet of recording paper is detected. Based on this information of lateral discrepancy, the writing start position for writing an image on the photosensitive drum in a scan line is adjusted such that the lateral discrepancy is absorbed. Thus, when the image is formed on the drum and then transferred onto the sheet of recording paper, there is obtained a predetermined relative positional relationship between the sheet of recording paper and the image in the lateral direction at all times.

    • A circuit for protecting a horizontal synchronous signal comprises a horizontal synchronous signal detecting circuit responsive to horizontal synchronous pulses included in a composite synchronous signal of a reproduced PCM signal, first and second horizontal synchronous pulse supplementing or adding circuits and an output switching circuit. The output switching circuit operates so that the first supplementing circuit delivers a first supplementary pulse in the absence of a single pulse of the original horizontal synchronous signal, and the second supplementing circuit produces one or more second supplementary pulses in the absence of a plurality of continuous pulses of the original horizontal synchronous signal. When the circuit returns to a condition in which produced horizontal synchronous pulses are synchronous with the original horizontal synchronous pulses, the time interval between adjacent pulses of the original pulses is detected to see whether the interval is either longer or shorter than a predetermined value. As a result, when a pulse first appeared after the returning point is within the predetermined interval, that pulse is removed so that the number of output horizontal synchronous pulses is correct.
    • 用于保护水平同步信号的电路包括水平同步信号检测电路,其响应包括在再现的PCM信号的复合同步信号中的水平同步脉冲,第一和第二水平同步脉冲补充或加法电路以及输出切换电路。 输出切换电路操作,使得第一补充电路在没有原始水平同步信号的单个脉冲的情况下传送第一辅助脉冲,并且第二补充电路在没有多个连续的情况下产生一个或多个第二辅助脉冲 原始水平同步信号的脉冲。 当电路返回到产生的水平同步脉冲与原始水平同步脉冲同步的状态时,检测原始脉冲的相邻脉冲之间的时间间隔,以查看间隔是否比预定值更长或更短。 结果,当在返回点之后首先出现脉冲在预定间隔内时,该脉冲被去除,使得输出水平同步脉冲的数量是正确的。
