Claims

[Scope of Claim for Utility Model Registration] (1) In a device that scans a document set on a contact glass while the document is pressed by a pressure plate, a document reference portion protruding along the periphery of the contact glass is provided. 1. A structure of a document setting section in a copying machine, etc., characterized in that a concave portion is formed and a convex portion that fits into the concave portion is formed on the lower surface of the pressure plate. (2) In a device that scans a document set on a contact glass while the document is pressed by a pressure plate, a positioning member that can be protruded and retracted is provided at a position along the periphery of the contact glass, and The positioning member is characterized in that when the pressure plate is opened, the positioning member projects upward to serve as a document reference portion, and when the pressure plate is closed on the contact glass, it is retracted downward to make the periphery of the contact glass stepless. Structure of a document setting section in a copying machine, etc.
