Abstract

A simple, low cost, hand operated paper feeder includes a media chamber mounted at an acute angle with respect to a horizontal plane that allows media to exit the chamber through a membrane. A two-position, T-shaped actuator including a pair of non-rotating rolls is slidably mounted on a rail for contacting the media. A rod is connected to the actuator such that when movement of the rod is initiated in a first direction, the actuator is moved to a position contacting the media and with continued movement of the rod, a top sheet of the media is moved a predetermined amount through the membrane, and with return of the rod in a second direction to its initial position, the actuator is caused to retract from the media surface to its initial position.
