Image reading device provided with structural features for fixing the reading unit during transport

摘要

An image reading device comprises: a frame; a reading unit provided with a line sensor for reading a text image; a guide member fixed to the frame for supporting the reading unit such that the reading unit is free to slide in a predetermined direction; and a stay fixed to the frame. A screwhole is formed at a predetermined position in the reading unit, a first throughhole is formed in the frame coaxially with the screwhole, and a second throughhole is formed in the stay coaxially with the screwhole and the first throughout. Further, an elastic member having a third throughhole engages with the first throughhole in the frame, and a holding member is provided comprising a grip of large diameter and a screw of small diameter. The reading unit is fixed, when the image reading device is transported, by screwing the screw into the screwhole of the reading unit through the second throughhole of the stay and through the third throughhole of the elastic member.
