IMAGE READING DEVICE AND CABLE REPLACEMENT METHOD

To solve such a problem that the work becomes ambitious and many man-hours are required when replacing a cable upon the replacement of an image sensor, since a frame and the like constituting a base body of an image reading device are required to be detached.SOLUTION: An upper unit that can open/close an upper portion of a lower unit comprises: a first reading section which is provided in a medium conveyance path and reads a surface of a medium which is conveyed; a substrate which is connected to the first reading section; a cable whose one end is connected to a first connection portion of the first reading section and whose other end is connected to a second connection portion of the substrate; and a detachable opposed portion which is a member opposite to a lower unit in such a state that the upper unit is closed. The first connection portion and the second connection portion are arranged apart from each other in the width direction intersecting the medium conveyance direction in the medium conveyance path. The cable is provided at a position where the cable is exposed when the opposed portion is detached.SELECTED DRAWING: Figure 6 【課題】イメージセンサーを交換する際にケーブルも併せて交換しようとすると、装置の基体を構成するフレーム等を取り外す必要があり、作業が大掛かりとなって多くの工数を要してしまう。【解決手段】下部ユニットの上部を開閉可能な上部ユニットは、媒体搬送経路に設けられ、搬送される媒体の面を読み取る第１読み取り部と、第１読み取り部と接続される基板と、一端が第１読み取り部の第１接続部に接続され、他端が基板の第２接続部に接続されるケーブルと、上部ユニットが閉じた状態において下部ユニットと対向する部材であって着脱可能な対向部と、を備え、第１接続部と第２接続部とは、媒体搬送経路における媒体搬送方向と交差する幅方向において離間して配置され、ケーブルは、対向部を取り外すことで露呈する位置に設けられる。【選択図】図６
