Claims

[Claims for Utility Model Registration] A carriage 1 that is movable along a platen 2, and printing that is provided on the carriage 1 and that can be selectively placed in a printing position that presses against the platen 2 and a release position that is separated from the platen 2. passing between the platen 2 and the printing head 5;
The print head 5 is arranged so as to be movable from one side of the print head 5 to the other side, and is arranged at a printing position.
a print ribbon 10 that is pressed against the printing paper supported on the platen 2 by a printer and is wound onto a take-up spool 12 after traveling between the platen 2 and the print head 5; a ribbon winding member 16 for rotationally driving the printing ribbon 1 on one side of the printing head 5;
Resistance applying members 13 and 14 that apply running resistance to 0
and when the printing head 5 is moved between the printing position and the release position, the resistance applying members 13, 1
In order to absorb the slack of the printing ribbon 10 that occurs between the printing head 4 and the take-up spool 12, a swinging member 3 swings in conjunction with the movement of the printing head 5.
9, a rotating member 34 that rotates as the swinging member 39 swings, and frictional contact between the rotating member 34 and the ribbon winding member 16, and the rotating member 34 Friction transmission member 3 that transmits the rotation of to the winding member 16
3. A printing device having a ribbon slack removing device, characterized by comprising the following.
