ABSTRACT:
In a printer with reciprocating carriage, a motor mounted on the carriage is used for up-down motion of the recording head, reciprocating motion of the carriage and sheet feeding motion so that the printer can be made compact and less expensive. The carriage engages with the sheet driving mechanism when it is positioned at the left end position to advance the recording sheet.
