１の基準値を上回ったとき超過パルス２５を出力する。When a resolution is designated by a switch operation, the operation unit 1 outputs a resolution instruction signal 20 instructing the scanning line density (standard: 3.85 lines/n++n, high resolution: 7.7 lines/h). The image reading unit 2 reads the original in accordance with the resolution instruction signal 20 and outputs a binary image signal 21, a phase signal 22 that determines the sub-scanning cycle, and a page end signal 23 that indicates the end of reading for each page. do. The first counter 3 receives the branched input of the binary image signal 21 and the phase signal 22, and outputs a scanning image density signal 24 that is obtained by counting the number of changes in the white signal and black signal for each scan. The first comparator 4 receives the scanning image density signal 2
4 exceeds a first reference value preset by the resolution instruction signal 20, an excess pulse 25 is output.

ウトするなどの動作を行う。The second counter 5 counts the excess pulses 25 and outputs a page density signal 26 when it receives the page end signal 23. The second comparator 6 outputs a control signal 27 when the page surface density signal 26 exceeds a second reference level preset by the resolution instruction signal 20. The alarm unit 7 performs operations such as displaying an alarm or printing out a page whose reading resolution is insufficient in response to a control signal 27.
