Abstract
PURPOSE: To make it possible to detect the original size for originals of any type, by combining the mechanical contact system and the optical system to constitute a device and by making one detection signal effective according to the thickness of originals.
CONSTITUTION: When the original put on original stand 1 is thick such as a book type, pattern E and counductive rubber 4 are separated from each other and become nonconductive. Consequently, signal (e) from pattern E becomes high level H, and AND gates G1WG4 are closed, and AND gates G5WG8 are opened, and the size detection signal from the detecting circuit 14 of the size of the optical original passes through these gates and is output. Next, when original 2 is a thin sheet, signal (e) from pattern E becomes low level L, and AND gates G5WG8 are closed, and AND gates G1WG4 are opened, and the size detection signal from the detecting circuit 6 for the original size of the mechanical contact system passes through these gates and is output. Thus, the size can be detected for originals of any type.
