摘要:
To provide a high-speed paper-feeding device for feeding slips or papers from the hopper by using a pick roller, featuring reduced misoperation, reduced noise, a higher paper-feeding speed and compactness. In the high-speed paper-feeding device, the bouncing motion of the pick roller that may take place at the beginning of the paper-feeding operation is suppressed by using a buffer device, the end portions only of the slips or the papers are pushed up/restored by a push-up device, that moves the arm up and down being driven by a solenoid that is provided at the bottom of the hopper, in order to reduce the burden for moving the hopper up and down born by the motor and the rack-and-pinion mechanism. Besides, the motion of the pick roller is detected at a moment when the rear end of the slip separates away from the pick roller to control the continuous feeding of the papers while eliminating dead time between the papers that are fed and enabling the papers to be continuously fed at high speed.
