Abstract
A hinge member 3 that is attached to a document pressing plate 2 and includes a tubular supporting leg 5, in which a projection member 7 is incorporated so that a tip 71a of the projection member 7 appears and disappears in an opening part 6, and a spring member 8 for always biasing the projection member so that the tip 71a of the projection member 7 projects from the opening part 6 is also incorporated. Thus, by attaching the tip 71a that projects from the opening part 6 of the projection member 7 to an inner wall surface 4a of the supporting hole 4, the tubular supporting leg 5 of the hinge member 3 can be securely fixed in the supporting hole 4 without jouncing.
