Abstract:
A sheet member feeding device comprising:a first gear transmitting a driving force to a feeding roller for intermittently feeding a sheet member per a predetermined feeding amount; a second gear having a first mark and a second mark representative of a maximum eccentric position and a minimum eccentric position along a radial direction relative to a predetermined concentric circle in a tooth space, in opposition to each other and directly or indirectly transmitting a driving force to said first gear; a third gear directly or indirectly transmitting driving force from driving means to said second gear; detecting means for detecting the first mark and the second mark in said second gear and transmitting a detection output; and a control portion operating said driving means for performing operation for rotating said second gear through 180Â° between said first mark and said second mark with respect to feeding for a feeding amount of said sheet member for one time, on the basis of the detection output from said detecting means.
