ABSTRACT:
In a printer for printing information onto a recording medium, rotation of a platen in a normal direction causes the recording medium to be transported in a normal-feed direction. Rotation of the platen in a reverse direction causes the recording medium to be transported in a reverse-feed direction opposite to the normal-feed direction. Discharge rollers are arranged above the platen for rotation about an axis parallel to a longitudinal axis of the platen at respective peripheral speeds higher than that of the platen. A rotation transmitting mechanism is arranged between the platen and the discharge rollers for transmitting rotation of the platen to the discharge rollers. The rotation transmitting mechanism includes a one-way clutch for permitting rotation of the platen in the normal direction to be transmitted to the discharge rollers to rotate the same thereby feeding the recording medium in the normal-feed direction, but for preventing rotation of the platen in the reverse direction from being transmitted to the discharge rollers.
