Abstract
A sheet handling device comprising a first roller (5) defining a reference surface which defines part of a sheet feed path along which sheets are fed, The roller (5) is mounted to a support (26) by arms (6) such that under normal working conditions the roller is fixed relative to the support, The arms (6) are biassed by a spring (12) to hold the roller (5) in its fixed position, the spring force being such that under abnormal conditions the roller (5) moves relative to the support (26) whereby the reference surface moves away from its sheet feed path defining position.
Claims12
A sheet handling device comprising a first member defining a reference surface which defines part of a sheet feed path along which sheets are fed a support and a mounting arrangement said first member being mounted to said support by said mounting arrangement such that under normal working conditions said first member is fixed relative to said support, said mounting arrangement being such that under abnormal conditions said first member defining said reference surface moves relative to said support whereby said reference surface moves away from its sheet feed path defining portion, a second member cooperating with said reference surface of said first member such that sheets can be fed between the members, said second member being movable relative to said reference surface and said support under normal working conditions in response to the thickness of sheets passing between said members.
