を設けたことを特徴とする印字装置のリボン送り装置。[Claims for Utility Model Registration] The carriage 8 on which the print head 9 is placed is mounted on the platen 6 and moves back and forth to the print head 9 via the print ribbon R.
A printing device that performs a printing operation includes: a drive member 13 that rotates forward and backward in conjunction with the reciprocating movement of the carriage 8; a ribbon feeding member 30 for feeding the printing ribbon R; and a driving member attached to the ribbon feeding member 30. The ribbon feeding member 30 is provided with a transmission mechanism 42744.46 having a first spring clutch 43 in order to transmit only one-way rotation of the ribbon feeding member 30. A second spring clutch 49 that applies a load only when the drive member 13 rotates in the other direction to open the first spring clutch 43 when the drive member 13 rotates in the other direction.
A ribbon feeding device for a printing device, characterized in that it is provided with.
