PURPOSE:To prevent the lack of image due to skew and prevent the useless copy by outputting a correction disable signal and stopping copying when the count number for clock pulses corresponding to the skew amount of the transported original copy is over the max. set number. CONSTITUTION:When skew sensors 31 and 33 detect an original copy at first, the first counter operates to count the number of clock pulses outputted from a clock pulse generator, and when sensors 32 and 34 detect the original copy, counting into stop. When the original copy has a large size, and the skew sensor 31 detects the original copy, the count number of the first counter is compared with the first set number, and when the count number is over the first set number, a driving signal is outputted from an output port P-1, and the count number and the first max. set number in the correctable skew amount are compared, and when the count number is over the max. set number, the output of the copying signal outputted from an output port Q is brought into stop, when the original copy is transported to a slit light exposure part 2, and the useless copy such as the lack of image can be eliminated. |
