Abstract
A sheet feed mechanism includes a chassis for supporting a stack of sheets; a top sheet engaging member for engaging a top most sheet of the stack; a stack engaging structure, a first end of the stack engaging structure engaging the stack of sheets to bias a top most sheet of the stack of sheets against the top sheet engaging member, the stack engaging structure being supported from the chassis by a resilient member; a friction surface extending perpendicularly from a second end of the stack engaging structure opposite to the first end; a lock mechanism having a lock arm hingedly connected to the chassis, the lock mechanism including a biased contact foot for engaging the friction surface to retard a rectilinear movement of the stack engaging structure; and an actuator for engaging and disengaging the contact foot from the friction surface.
