PURPOSE:To allow one detecting means to detect that an original is set in a home position by providing the means detecting that an original is set in the home position of an original placing glass inside a corner made by two sides orthogonally intersecting with an original positioning scale. CONSTITUTION:The machine is so designed that the original M is placed on the original placing glass 10 on a single reference basis. The means 90a detecting that the original M is set in the home position of the original placing glass 10 is provided inside the corner made by two sides orthogonally intersecting with the original positioning scale. Moreover, another original detecting means is provided inside the minimum original size of the original positioning scale. Consequently, even if the original M runs onto the original scale to be set abnormally, that can be detected. Simultaneously, the opening and closing of the original cover plate can be detected. |
