Pinch roll nipping releaser in paper feeding mechanism for copying machine

Abstract

Abstract PURPOSE:To make the copying paper nipped between rolls releasable in an easy manner, by making up part of a paper feeding mechanism at the takeout side of a paper feeding unit of a support guide into a taper form, in case of the paper feeding mechanism coupling the paper feeding unit with a copying machine body via the support guide. CONSTITUTION:When a paper feeding unit A comes into a state of being set in operation, a roll support 6 is situated on the horizontal part of a support guide 7 whereby a takeout roll 3 and a pinch roll 5 both are held in a state of being nipped. And, in time of changing the copying paper, if the paper feeding unit A is moved in an X direction, the takeout roll 3 remains in keeping its height intact but the nip roll side of the roll support 6 mounted on the support guide 7 goes down along a taper part 8 installed in the support guide 7 as rotating downward centering on a shaft 6'. Therefore, when the paper feeding unit A reaches a broken line position, nipping at both rolls 3 and 5 is released, so that the copying paper existing between both these rolls 3 and 5 can be easily taken out.
