Abstract:
A sheet member feeding device comprises 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 the first gear, a third gear directly or indirectly transmitting driving force from driving means to the second gear, detecting means for detecting the first mark and the second mark in the second gear and transmitting a detection output, and a control portion operating the driving means for performing operation for rotating the second gear through 180° between the first mark and the second mark with respect to feeding for a feeding amount of the sheet member for one time, on the basis of the detection output from the detecting means.
