    • A signal output board includes: a drive signal generation section configured to generate a drive signal for a CCD; an inverse signal generation section configured to generate an inverse signal by inverting a phase of the drive signal from the drive signal generation section; a first signal transmission line portion configured to transmit the drive signal from the drive signal generation section; a second signal transmission line portion configured to transmit the inverse signal from the inverse signal generation section, at least part of the second signal transmission line portion being arranged in parallel to and adjacent to the first signal transmission line portion; an output end portion configured to output the drive signal transmitted by the first signal transmission line portion, to the outside; and an equivalent load section including a load equivalent to a transmission path for the drive signal from the output end portion to the electronic device, the equivalent load section being connected to an end portion of the second signal transmission line portion.
    • 信号输出板包括:驱动信号生成部,被配置为产生用于CCD的驱动信号; 逆信号生成部,被配置为通过使来自驱动信号生成部的驱动信号的相位反相来生成反相信号; 第一信号传输线部分,被配置为从驱动信号产生部分发送驱动信号; 第二信号传输线部分,被配置为从反向信号产生部分发送反向信号,所述第二信号传输线部分的至少一部分平行布置成与第一信号传输线部分相邻; 输出端部,被配置为将由第一信号传输线部分发送的驱动信号输出到外部; 以及等效负载部分,其包括与从输出端部分到电子设备的驱动信号的传输路径相当的负载,等效负载部分连接到第二信号传输线部分的端部。

    • An endoscope includes: a CCD that picks up an image of a subject; an FPGA that is controlled by a main body portion 3 to output a drive signal for driving the CCD and transmits an image pickup signal outputted from the CCD to the main body; rewritable flash memory in which at least one of program data and setting data that relate to an operation of the FPGA is stored; and a switch group that, based on a rewriting instruction signal SW to the data in the flash memory, switches so that the data received by using all or a part of signal lines for the CCD, the lines being associated with observation of the subject, is inputted to the flash memory.
    • 内窥镜包括:CCD,其拾取被检体的图像; 由主体部分3控制的FPGA,以输出用于驱动CCD的驱动信号,并将从CCD输出的图像拾取信号发送到主体; 其中存储与FPGA的操作相关的程序数据和设置数据中的至少一个的可擦写闪存; 以及开关组,其基于对闪速存储器中的数据的重写指令信号SW切换使得通过使用用于CCD的全部或一部分信号线接收的数据,与对象的观察相关联的线, 被输入到闪速存储器。
