Copying machine with audible indicator means

Claim 1

An audible indicator means for use in a copying machine, comprising: a plurality of detector means for monitoring the operating condition of the copying machine; memory means for storing therein a plurality of operational statements indicative of the operation and the operational condition of the copying machine; control circuit means connected between the detector means and the memory means for selecting respective ones of the statements from the memory means in response to the outputs from the detector means and for developing an output signal indicative of the selected statements; and an audible sound generation means responsive to the output signal from said control circuit means for converting the selected statements into audible sounds indicative of the operation and the operational condition of the copying machine; said control circuit means including a plurality of flip-flop means respectively connected to said plurality of detector means, said flip-flop means each developing an output signal indicative of the respective operational condition associated with its respective detector means; a plurality of decision circuit means respectively connected to said plurality of flip-flop means for deciding whether a set output signal is being generated from its respective flip-flop means; control circuit means connected to said decision circuit means for developing micro-instructions in response to the respective set output signals from said flip-flop means; and means responsive to the micro-instructions for selecting the respective ones of the operatinal statements from the memory means in response thereto.
