Abstract
PURPOSE: To prevent erroneous operations for form selective feed and the fault of the device, by providing a detecting electrode provided on the original stop material and a transparent electrode provided on the original stand surface and by detecting the original size by the contact degree between both electrodes.
CONSTITUTION: Detecting electrodes 2 consisting of, for example, conductive rubber are provided in original detection positions on platen cover 1, and transparent electrode 3 formed by conduction working is provided in the position opposite to electrodes 2 on a part of original stand glass 5. When platen cover 1 is closed, the output is generated due to conduction in detecting electrodes which are opposite to and are brought into contact with the part of transparent electrode 3 which is not shielded by original 4 put on original stand glass 5, and no output is generated in detecting electrodes opposite to the part of transparent electrode 3 which is shielded by the original, so that the original size can be detected by presence or absence of output information of detecting electrodes 2.
