PURPOSE:To drive an electromagnetic counter with simple constitution and to obtain a device with high-reliability by arranging position detecting means for an exposure scan in a scanning direction at specific intervals, and using their output signals as an exposure scan stop signal and an electromagnetic counter driving signal. CONSTITUTION:For example, a CPU turns on an exposure lamp 2 during an A4 size exposure scan, an original exposure scanner 1 moves on a rail 4, and a microswitch plate 3 turns on a microswitch 5. Then, a total size counter 8 starts and the CPU inputs an L-level signal from a line 10 to stop the scanner 1 from making a scan, and the lamp 2 is turned off by a signal from the CPU and the scanner 1 returns. At this time, the switch plate 3 leaves the switch 5 and the counter 8 goes up by one. The switch plate 3 or switch 7 is operated during an A3 size exposure scan. Thus, a gate circuit is omitted. |
