Abstract

PURPOSE: To positively prevent erroneous actions, by detectig whether a master is set on a plate cylinder thereby to obtain a signal, and controlling actions for feeding or removing the plate using the signal.
CONSTITUTION: (i) When the master 7 is set on the plate cylinder 6, the output from a master detecting signal generating member 11 is (1), and inputs of AND gates 14, 15, 16 are (0), (0), (1), respectively (numeral 13 denotes an inverter), and when there is a signal from an end cycle commanding signal generating member 3, though an end cycle actuating member 4 (reference numeral 17 denotes on OR gate ) and a plate removal error detecting member 5 are actuated to remove the plate, while a plate feeding actuating member 2 does not work, even if a plate feeding commanding signal generating member 1 issues a signal. On the other hand, (ii) in the case when the master 7 is not set, when there is a plate feeding commanding signal, the member 2 is actuated to feed the plate, but since the member 4 works and and member 5 does not work, even if an end cycle commanding signal is provided, the operation of the printer would not be stopped.
