Claims

[Claims for Utility Model Registration] A printing device in which a carriage 13 carrying a ribbon cassette 16 and a printing element 23 moves step by step along the printing line of the platen 11 based on a printing signal to perform a predetermined printing operation, The ribbon cassette 16 is supported by the carriage 13 so as to be swingable between a rest position and a printing position;
a swinging means 18 for swinging the carriage 13 to the printing position prior to the stepwise movement based on the printing signal;
a rotating member 31 rotatably supported by the carriage 13 and rotating as the carriage 13 moves along the print line; and a rotating member 31 rotatably supported by the carriage 13 for positioning a new portion of the ribbon at the printing point of the platen 11. a ribbon feeding drive member 45; and a connecting means provided between the ribbon feeding drive member 45 and the rotating member 31, and connecting the two members 45° 31 only when the ribbon cassette 16 is swung to the printing position. The connecting means includes: a first member 32 that is always connected to the rotating member 31;
1. A second member 38 which is always connected to the ribbon feeding drive member 45; and a second member 38 which is provided between the first and second members 32 and 38 and which is always in a released state and which is connected to the ribbon cassette 16. A ribbon feeding mechanism for a printing device, characterized in that the ribbon feeding mechanism is comprised of a printing position -\a clutch mechanism 42, 54 which forms a coupled state when swung.
