Abstract

PURPOSE:To prevent forgetteing to take away an original on a copier, by setting in series a switch to be turned off when the original is taken away from the contact glass and a switch to be adversely interlocking the power supply switch and then connecting these switches to a circuit of an alarm element like a buzzer, etc. CONSTITUTION:An original is put on the contact glass, and a press-contacting plate 2 is closed to turn on a power sounrce switch. Then a start button is pushed to start the copying. When the copying is over and the power source switch is turned off, a switch Sm is turned on. In this case, if the plate 2 is kept closed, i.e., the original is left on the glass 1, an original detection switch S0 is kept off with no operation of a relay R1. Accordingly a normally closed contact S1 is kept on, and a buzzer B operates as soon as the switch Sm is turned on to give an alarm. In such way, the forgetting to take away an original on a copier can be prevented.
