Abstract: PROBLEM TO BE SOLVED: To warn that the established copying number exceeds an allowable number for a copying process at the time of setting the reservation of a single job by providing a comparison means and a warning means. SOLUTION: CPU to perform a control job regarding input signals from various operation keys and a display function, computes a job sheet number on the basis of a registered number, a copying mode and a document number, upon receipt of information about the end of a document counting process. Furthermore, when the job sheet number computed with a processing part B exceeds the residual number of a division, the CPU performs a warning display process for explaining to that effect, for example, the indication of a key or the like for invalidating or rounding (i.e., setting smaller number) as a reservation mode. When the document number is not over the residual number of the division, the registered number is rounded so as to keep the computed job sheet number within the residual number of the division, provided that a rounding process is selected as the reservation mode.

Abstract: PROBLEM TO BE SOLVED: To suppress the duty change of an output pulse signal, which is accompanied by the duty change of an input clock signal, and to realize stable pulse modulation by controlling delay quantity by setting timing to be an operational reference not as the duty of a reference clock signal but as period timing. SOLUTION: A delay circuit 3 delays a signal CLK2 obtained by frequency- dividing the reference clock signal CLK into two by a frequency divider 2 in n-stages, and delay signals D1 -Dn are outputted to a pulse generating circuit 4. The circuit 4 inputs the signals D1 -Dn , and outputs pulse signals D1 '-Dn ' to a delay quantity detection circuit 5. The circuit 5 detects the delay quantity from the output levels of the signals D1 '-Dn '. An arithmetic circuit calculates a correction value with respect to a value which has been previously set, based on the delay quantity and a selection means selects one desired signal among the signals D1 '-Dn ' which the circuit 4 outputs based on the correction value. Thus, an appropriate pulse signal is obtained, regardless of the duty of the signal CLK.
