ABSTRACT:
In a serial printer a pinion and a rack for lateral movement of a carriage, a dislodging member with edges proximate to the rack is provided to remove any chads or other foreign matters that may be attached to the rack, as they approach the pinion with the lateral movement of the carriage. The chads or other foreign matters are prevented from being caught between the pinion and the rack, and noises and increase in the torque due to the rolling in is prevented.
