Abstract

PURPOSE: To prevent check errors by detecting copying paper at the specified timings according to set modes.
CONSTITUTION: A copying material detecting switch provided in the conveying path of copying materials, a means which sets the copying modes such as large and small of copying sizes, etc. and a circuit which detects the jam of the copying material in the conveying path of the copying materials through combination of detection switch and mode set means are provided. When the detection switch is not detecting the copying material at the mutually differing first and second timings corresponding to the mutually differing first and second modes having been set by the mode set means, it is judged to be jam, whereby safety measure is executed.
