Abstract
PURPOSE: To prevent an original from being left behind by sounding an alarm when the cover of a copy container is opened in a state of the original left on a set position after completion of copying.
CONSTITUTION: Reflecting member r is provided on part of pressing board 2, and light source L for illuminating member r through glass 1, and photoelectric converting element PE for receiving the light reflected from member r are installed, and presence or absence of original 0 on glass 1 is detected by change of output of element PE. A detection signal is generated with microswitch MS acting in response to opening and closing of transparent cover 5 of copy container C. Each detection signal is applied to control signal generating circuit CS and this provides a control signal to alarm device AR when a detection signal is obtained from MS and original 0 remains on a set position.
