The original glass 3 is directly held on the receiving surface 2b of the side frame 2, and the optical head 1 is slid on the sliding surface 2a, so that the optical head and the original to be read are always kept at an equal interval. At the time of scanning, the original is placed on the original cover (not shown).
) Is pressed against the original glass. Also, during reading, the sliding tip 1a fixedly attached to the optical head 1 slides on the sliding surface 2a, but the side frame 2 uses a lubricated surface-treated steel sheet having excellent slidability. 1
This allows stable driving without squealing and chattering, and the sliding tip 1a is also excellent in wear resistance.

As shown in FIG. 3, a linear projection 4b is formed at the tip of the side frame 2 from the lower case 4, and Is shielded from the appearance. Generally, the fractured surface of the end surface of the surface-treated steel sheet including the lubricated surface-treated steel sheet was not plated, and the appearance visible to an operator through the original glass 3 was significantly impaired due to rust or the like. According to the present embodiment, the end face is shielded from the operator by a simple method of forming the protrusion linearly along the cut surface of the side frame by the resin constituting the lower case, so that the appearance is less expensive than the extruded aluminum material. For the first time, a side frame that is comparable to that available will be available.
