Abstract
Abstract A count control apparatus for controlling a photocopying machine is constructed to be enabled by a copy command signal to effect repetitive photocopying operations and to generate a sheet number pulse for each photocopying operation wherein a desired number of sheets being photocopied by said photocopying machine is preset by a keyboard or the like. The sheet number pulses are counted, the preset number is compared with the count number, and the copy command signal is generated in response to a comparison of the count value with the preset value. Normally the copy command signal is conditioned by a comparison of the count number with the preset number. However the copy command signal is prevented from being conditioned by the comparison in response to a manual changing of the presetting whereby the copy command signal is conditioned in a different manner during the changing of the presetting, whereby a differently conditioned copy command signal is provided. After the preset number is changed manually to a new desired preset number, the copy command signal is again conditioned by said comparison but responsive to the manual completion of the presetting change mode.
