Abstract:
An apparatus for feeding rolled paper comprising:rolled paper; a feed mechanism for feeding a portion of the rolled paper in a predetermined direction; a cutting unit for cutting the portion of the rolled paper into a sheet of desired length; a driving source for actuating the feed mechanism and the cutting unit; a first gear train interposed between the driving source and the feed mechanism; and a second gear train interposed between the driving source and the cutting unit,wherein the first gear train includes a feed gear for driving the feed mechanism;wherein the second gear train includes a cutter gear for moving a movable cutter of the cutting unit between a non-cutting position and a cutting position; anda reverse feed gear comprising an integral part of the cutter gear for transmitting driving force for the cutter gear to the feed gear interposed between the first gear train and the second gear train;the apparatus being operable such that when the portion of the rolled paper is to be fed, the second gear train is held in a non driving connection state and the first gear train is held in a driving connection state, thereby transmitting the driving force from the driving source to the feed mechanism via the first gear train and rotatively driving the feed mechanism in the predetermined direction;when the portion of the rolled paper is to be cut, the second gear train is held in a driving connection state and the first gear train is held in a non driving connection state, thereby transmitting the driving force from the driving source to the movable cutter via the second gear train and moving the movable cutter from the non-cutting position to the cutting position and then from the cutting position to the non-cutting position; andwhen the movable cutter moves from the cutting position to the non-cutting position, the reverse feed gear connects the first gear train with the second gear train, thereby transmitting the driving force for the cutter gear to the feed gear via the reverse feed gear and rotatively driving the feed mechanism in a direction opposite to the predetermined direction.
