摘要： A sheet from the top of a stack of media, and is driven by a reversible electric motor operated in a forward direction to drive a feed roll and nudger roll; and operated in a reverse direction to drive a cam profiled to raise and lower the nudger roll. One-way clutched gears may be provided to restrict rotation of the feed roll and the nudger roll when the motor is operated in a reverse direction; and to restrict rotation of the cam when the motor is operated in a forward direction. A rotary cam may be profiled to allow for the reciprocating movement of the nudger roll from a down position in which the nudger roll contacts the top of the stack of media to an up position in which the distance between the nudger roll and the top of the stack of media is suitable for loading media onto the stack of media.

摘要： A registration gate is mounted in a sheet feeding mechanism for rotation about an axis at about right angles to the direction of sheet feed into a feeder mechanism. The gate includes a plurality of fingers extending upwardly through slots in the tray. A motorized sequencing cam moves followers to rotate the gate to an open position to retract the fingers below the tray, to raise and lower a nudger in and to move a lever for locking and unlocking the gate into the closed position with the fingers upright for registering the leading edge of the sheets during user loading of the tray. The cam may be detented or locked by a pawl engaging a notch in the cam.

摘要： A simplified sheet sensor and registration gate for feeding print media sheets from a stack loaded by a user into a receptacle on a photocopier. The gate is pivoted on the mechanism and has a flag attached; and, upon user loading of sheets into the receptacle, the gate is pivoted against a locking arm and the flag is moved to actuate an optic sensor that sheets have been loaded. The locking arm is pivoted on the nudger roll arm and unlocks the gate when the nudger roll is moved down to contact the top sheet in the stack. When the sheet receptacle is unloaded, the gate is pivoted by gravity to the downward position and the locking arm pivots by gravity to reset. If the nudger is raised for sheet jam clearance, the locking arm is pivoted to clear the gate, allowing the gate to drop. The locking resets by gravity.
