Abstract

PURPOSE: To optimize controlling paper feeding pressure in such a way that in a paper feeding equipment in which the paper feeding pressure is set by means of a spring, the paper edge position is detected, it is memorized as being a slip rate, and displacing rate of a spring suspending position is counted and controlled by the memorized value.
CONSTITUTION: Paper feeding pressure is changed through a spring 1 in such a way that a screw rod 2 is moved up and down through a worm 8 and a wheel 3, by forward and reverse rotation of a motor 9. On another hand, output from photosensitive elements 33 to 36 which receive light through a hole for a paper guide 42 is read into a μ processor with interruption due to pulse signals from a photosensitive element, and slip rate of the paper is detected. Though this rate moves ahead against arresting force of a paper dealing rubber 29 by frictional force with the paper to be fed for the previous time, if the paper feeding pressure is strong, the advance rate is enlarged. Since the motor 9 is turned in forward or reverse direction by means of previous read-in value, paper feeding pressure is controlled by detecting the spring position using a slit plate 14 of a screw rod 2 and photosensitive elements 10, 12.
