PURPOSE:To facilitate the adjustment of the printing position with a simple construction by delaying a signal to be provided to a tractor controlling circuit from a print controlling circuit. CONSTITUTION:As soon as a print start signal is inputted into a control circuit 1 from an upper unit, a print signal is provided to a video signal output circuit 2, which provides a video signal to an optical unit 3 to allow information to be written onto a photosensitive drum 4. A delay circuit 5 into which a tractor start signal was inputted from the circuit 1 outputs a signal delayed by time set with a vertical position setting switch 6 for adjusting mechanical position. With a delay circuit 7, a signal delayed by time set with a vertical position setting switch 8 on an operator panel 1 is provided to a control circuit 9, which drives a tractor 12 with motors 10 and 11. |
