Printing apparatus

摘要

A printing apparatus includes a driving gear on a carriage rotated in accordance with the movement of the carriage, a spool shaft rotatable only in one direction for rotating a ribbon spool of a ribbon cassette, and a rotation transmitting mechanism having first and second releasing members provided between the driving gear and the spool shaft for operatively interlinking the driving gear to the spool shaft to rotate the spool shaft in the one direction in accordance with the movement of the carriage in the forward direction. The first releasing member is driven by a print head and releases an operational interlink between the driving gear and the spool shaft when the print head is disposed at a non-printing position. The second releasing member releases the operational interlink in accordance with the movement of the carriage in the reverse direction.
