Abstract
PURPOSE: To effectively prevent jam and damage of an original figure, by detecting an original figure feeder released from an original figure platen, and giving an alarm.
CONSTITUTION: When an original feeder is lifted up, inverter I3 is turned on, and flip-flop FF2 is turned on. When the original feeder is again set, AND circuit A7 is turned on, and AND circuit A8 is turned on with an exposure signal in exposing the original, flip-flop FF3 is turned on, and an alarm for preventing the original from being mislaid is indicated. Output of the last exposure completion signal of AND circuit A11 turns on AND circuit A9, actuates timer T2, and after a given time, gives the alarm for preventing original mislaying.
