Image reading apparatus and method of manufacturing image reading apparatus

A method of manufacturing an image reading apparatus, the image reading apparatus including a main unit, an openable unit coupled to the main unit, a cable extending between the main unit and the openable unit, and a holding member configured to hold the cable routed in the main unit, the main unit including a document support surface configured to support a document on the document support surface, and a reading unit configured to read an image of the document supported on the document support surface, the openable unit being configured to move up and down relative to the main unit and to pivot about an axis between a closed position where the document support surface of the main unit is covered and a released position where the document support of the main unit is exposed, the openable unit including an electric component and a feeding unit configured to feed a sheet along a feed path, the reading unit of the main unit being configured to read an image of the sheet fed along the feed path, the cable being connected to the electric component of the openable unit and routed in the main unit, the holding member including a first guide portion configured to guide the cable in a specified direction within the main unit and hold a first specified portion of the cable routed in the main unit, the method comprising:

• locating the openable unit in the closed position;
• attaching the holding member, in a first position, to the main unit;
• putting the cable in the holding member attached in the first position to the main unit such that the first guide portion holds the first specified portion of the cable and the cable has no slack in a second specified portion of the cable, the second specified portion being closer to an end of the cable disposed in the openable unit than the first specified portion;
• and
• moving the holding member from the first position to a second position such that the first guide portion holds the first specified portion of the cable and the cable is slack in the second specified portion of the cable, the holding member being closer to the openable unit in the second position than in the first position.
