<p>PURPOSE:To reduce correction time by controlling stoppers wth the timers being operated with the signal from the plural number of paper detectors. CONSTITUTION:Plural number of paper detecting sensers 8-1 to 8-4 are arranged to the rear of the paper feeding rollers 6, and plural number of stoppers 9 are arranged to further rear of them; and input circuit 10 which issues derivative pulse a by the switching on of the detector 8, and stopper control circuit are constituted by adding the output of timers IC12 and 13 to the base of the transister 16 for the operation of the solenoid 15. When the paper 2 is inclined and the detector 8-1 is on, IC12 and 13 are set and reset respectively by output pulse a-1, and the IC13 is set by the reset of IC after a certain time, and the operation of the stopper 9 is continued. Then the detectors 8 are successively on, and the same operation is repeated, and the solenoid 15 stops when the leading edge of the paper 2 is alined at the stoppers 9.</p> |
