Abstract
A sheet transport apparatus has opposed sheet transport guide baffles defining a sheet transport path having an upstream and downstream direction and, a switch adjacent the path to detect the presence of a sheet in the path, the switch having a main switch body fixedly mounted adjacent the path, a switch actuator movable between a rest position and a switch actuated position including an actuator arm having a free end and being pivotally mounted on an actuator pivot at the other end to the main switch body and movable between a position associated with the said rest position and switch actuated position, a switch actuator tip pivotally mounted to the free end of the actuator arm and movable between a first position extending the length of the arm into said path detecting the presence of a sheet in the path and a second position pivoted toward the sheet transport upstream direction out of the sheet transport path, the actuator tip being spring biased to the first position enabling positive switch actuation by the passage of a sheet in the downstream direction of the path and passively movable to the second position against the bias by the removal of a sheet from the path in the upst…
