Abstract:
1. A scanner unit comprising: a carriage provided with a frame extending in a first direction along a document surface of a document set substantially horizontal, and an optical member mounted on the frame for illuminating the document surface and guiding light reflected from the document surface to light receiving means; a rail extending along the document surface in a second direction perpendicular to the first direction, and mounting thereon the frame such that the frame can slide in the second direction; a first inhibiting element having a slit which receives a part of the frame when the carriage has slid along the rail to a hold position, said first inhibiting element inhibiting a movement of the frame when the carriage has slid to the hold position in the first and second directions; and a second inhibiting element for holding another part of the frame together with the rail when the carriage has slid to the hold position, thereby inhibiting a vertically upward movement of the frame.
