    • An image forming apparatus including photoconductor drums corresponding to colors, motors, gears to transmit each rotation of the motors to each of the photoconductor drums, each of two gears comprising a portion to be detected intermittently continuing in a circumferential direction at a position having same radius centering around a rotary shaft of the gears, a pair of phase sensors to output detection signals of signal logics according to an existence or a non-existence of the portion to be detected at a point symmetric position centering around the rotary shaft of each of two gears and a control unit to calculate a rotation phase difference between each of the gears based on a logical combination of the detection signals which are output from the pair of phase sensors and to control the motors so as to synchronize rotation of each of the gears based on the calculated rotation phase difference.

    • A video device comprises: a video signal processor generating a standard definition video signal at least having a composite signal and a high definition component video signal; an outputting unit outputting the standard definition video signal or the high definition component video signal to a cable to be connected; a discriminating unit discriminating a kind of cable connected to the outputting unit; and a switch allowing the outputting unit to selectively output the standard definition video signal and the high definition component video signal on the basis of the discrimination result of the discriminating unit. When the discriminating unit determines that the cable connected to the outputting unit is a cable for a high definition signal, the switch allows the outputting unit to output the high definition component video signal.
    • 视频设备包括:视频信号处理器,生成至少具有复合信号和高分辨率分量视频信号的标准清晰度视频信号; 输出单元,将标准清晰度视频信号或高分辨率分量视频信号输出到要连接的电缆; 识别单元,鉴别连接到所述输出单元的电缆的种类; 以及允许输出单元基于鉴别单元的识别结果选择性地输出标准清晰度视频信号和高分辨率分量视频信号的开关。 当识别单元确定连接到输出单元的电缆是用于高分辨率信号的电缆时,开关允许输出单元输出高分辨率分量视频信号。
