    • An image reading apparatus includes a carriage for holding a film holder holding a film, a motor for moving the carriage, and a housing for holding the carriage and the motor. While the motor moves the carriage, a first portion of the carriage is positioned by being slidably clamped by the housing, and a second portion which is in the opposite side of the first portion of the carriage is slidably positioned by a guide shaft. An image reading apparatus includes an image sensor for sensing an image from an original, a conveyor for conveying the original, a first board on which an image processing circuit for performing predetermined processing for an image signal output from the image sensor is mounted, and a second board on which a power supply circuit for supplying power to the image processing circuit is mounted. The first and second boards are arranged to be parallel to each other, and the conveyor means conveys the original to cause the original to pass through a space enclosed with the first board and the second board. An inlet is formed in a lower part of a space enclosed with the first board and the second board, and an outlet is formed in an upper part of the space. The conveyor conveys the original while keeping the original parallel to the first or second board. The original is translucent.
    • 图像读取装置包括用于保持保持膜的胶片保持器的滑架,用于移动滑架的电动机和用于保持滑架和电动机的壳体。 当马达移动托架时,托架的第一部分通过由壳体可滑动地夹紧而定位,并且位于托架第一部分相对侧的第二部分由导向轴可滑动地定位。 图像读取装置包括用于感测来自原稿的图像的图像传感器,用于传送原稿的传送器,安装用于对从图像传感器输出的图像信号执行预定处理的图像处理电路的第一板,以及 第二板,其上安装有用于向图像处理电路供电的电源电路。 第一和第二板被布置为彼此平行,并且输送装置输送原件以使原稿通过由第一板和第二板包围的空间。 入口形成在与第一板和第二板包围的空间的下部中,并且在该空间的上部形成出口。 输送机传送原稿,同时保持原稿平行于第一或第二板。 原来是半透明的
