字装置全体が大きくなる等の欠点があつた。 Since conventional endless ink ribbon cassettes are provided with guides to the print section in only one direction, two endless ink ribbon cassettes are required for printing devices having multiple print heads. Therefore, the structure of the ribbon feeding drive mechanism is more complicated than that of a single ribbon feeding mechanism, and the cost is also increased.
Furthermore, maintenance of two endless ink ribbon cassettes is difficult, and a larger space is required than in the case of one endless ink ribbon cassette, resulting in disadvantages such as an increase in the size of the entire printing device.

Reference numeral 12 denotes a guide roller provided on a first surface S1 having the exit opening 11b and the entrance opening _11c , which is parallel to the first surface _S1 and guides the ribbon exiting from the exit opening 11b. 1 perpendicularly to the cassette body 1.
1 is rotatably supported. Reference numeral 15 denotes a guide shaft which is perpendicular to the first surface _S1 and from approximately the center between the outlet opening 11b and the inlet opening 11c in order to twist the ribbon 1 from the guide roller 12 at right angles. It is provided near the center of the width dimension (slightly larger than the ribbon width) of the guide roller 12 near the exit opening 11b. Reference numeral 13 denotes a guide roller, which is connected to the entrance opening 11.
It is provided in the proximal chamber of c in parallel to the first surface _S1 rotatably supported by the cassette main body 11. Reference numeral 14 denotes a guide roller, which is rotatably supported by the cassette body 11 from the guide roller 13 to the center of the cassette body 11 in parallel to the guide roller 13. Reference numeral 16 denotes a guide shaft, which is erected on a first surface S ₁ provided so that the ribbon 1 does not come into contact with the guide roller 14 . Further, reference numerals 19, 20, 21, and 22 are ribbon guides that guide the ribbon 1 to the height of the printing units 17 and 18, respectively. It is held at a predetermined angle by a lock arm 11d disposed on the cassette body 11 so as to withstand the tension of the printer. They are each supported so that they can be folded and stored. In the endless ink ribbon cassette configured in this manner, the ribbon 1 is transported from the ribbon storage section 11a to the outlet opening 11b and the guide roller 12.
Then, this ribbon 1 is removed from the guide roller 12.
The first surface is parallel to the first surface _S1 .
S ₁ and then twisted at right angles on the guide shaft 15, so that the width direction of the ribbon 1 is made perpendicular to the first surface S ₁ . Next, after passing through the guide shaft 16, it proceeds along the first plane _S1 , and then passes through the ribbon guide 21, and after being bent twice at right angles and changing direction by 180 degrees,
It is sent to the printing section 17. After passing through the printing section 17, the ribbon is bent at right angles by the ribbon guides 19 and 20, and the direction is changed again by 180 degrees, and then sent to the printing section 18, which is arranged opposite to the printing section 17. Furthermore, the ribbon 1 that has passed through the printing section 18 is changed direction again by 180 degrees by passing through the ribbon guide 22, and is twisted back to its original state at right angles until it reaches the guide roller 14. , and the first surface S ₁ becomes parallel.
After that, it passes through the guide roller 13 and the entrance opening 11c, and returns to the ribbon storage section 11.

In addition, although the parts of each corner of the ribbon guides 19, 20, 21, and 22 that bend and guide the ribbon at right angles are integrated in the figure, rotatable guide rollers may also be used for these parts. . Furthermore, in the figure, the printing direction of the print heads 23 and 24 is upward for the print head 23 and downward for the print head 24, but the ribbon guides 19, 20, 24 are
By changing the lengths of 1 and 22, the combinations of downward and upward, downward and downward, and upward and upward can be freely selected.

果が得られる。 As described above, according to this invention, the guide rollers 12, 13, 14 and the guide shaft 1 are arranged along one side of the first surface _S1 etc. of the ribbon storage section 11a.
5, 16 and the first to eighth guide members such as ribbon guides 19, 20, 21, 22 that can be folded and stored. Whereas two ink ribbon cassettes were required, it is now possible to supply ink ribbon to two printing units with one endless ink ribbon cassette. This not only makes it easier to maintain the endless ink ribbon, but also simplifies the structure of the ribbon feeding mechanism and makes the entire printing device more compact.
In addition, especially by providing the second and third guide members, the ribbon can be smoothly twisted (orthogonally transformed) to effectively prevent deformations such as distortion and wrinkles from occurring in the ribbon. Effects such as being able to do this can be obtained.
