ABSTRACT:
A sheet feeding apparatus having a track for guiding a sheet therein, with the track having an upstream end and a downstream end, and with a staging area located therebetween. Transport rollers are used for moving a sheet from the upstream end towards the downstream end. The apparatus also comprises control means including a stationary member and a moveable member located at the staging area; the moveable member is moveable between first and second positions with regard to said stationary member and one of the transport rollers. The moveable member, when in the first position, is operatively uncoupled from a transport roller and is operatively coupled to said stationary member to stop a sheet therebetween at the staging area, and the moveable member, when in the second position, is operatively uncoupled from the stationary member and is operatively coupled to one of the transport rollers to move the sheet from the staging area towards the downstream end. The control means also includes actuators for moving the moveable member between the first and second positions.
