ABSTRACT:
A recording apparatus comprises a carriage for carrying a printing head capable of recording on a recording sheet, a drive belt secured to the carriage for reciprocating the carriage relative to the recording sheet when the drive belt is driven, a rotatable feed roller for feeding the recording sheet past the printing head when the feed roller is driven, a reversible motor having a rotatable motor shaft, a drive pulley mounted to the motor shaft, wherein the drive belt passes over the drive pulley to reciprocate the carriage when the motor shaft is rotated in different directions, a worm wheel mounted to the feed roller to rotate therewith to feed a recording sheet when the worm wheel is rotated in a predetemined direction, a worm gear mounted to the motor shaft, wherein the worm gear meshes with the worm wheel to rotate it in different directions when the motor shaft is rotated in respective different directions, and a one-way clutch cooperating with the said feed roller and the worm wheel to transmit the rotation of the worm wheel to the feed roller only in the predetermined direction.
