Abstract

PURPOSE:To enhance printing efficiency and obviate troubles such as wasteful feeding of a ribbon and bending of the ribbon, by a construction wherein two ribbon cassettes are stacked so that the take-up direction of a ribbon in one of the cassettes is opposite to that in the other, and the two cassettes are shifted up or down in accordance with forward or backward movement of a carriage. CONSTITUTION:When printing while moving the carriage 5 in a forward direction F, a cassette holer 11 is shifted downward by an operating motor 18, so that the upper ribbon cassette 12 is located in front of a heating part 6a of a printing head 6. In this condition, while the carriage 5 is moved in the forward direction F by clockwise rotatory movement of a timing belt 8, thermal transfer printing on a printing paper through the ribbon 16 in the cassette 12 is conducted by the head 6 turned to a printing position. In the forward printing, a moving focre of the belt 8 is transmitted to a driving shaft 30 on one side, so that a take-up spool 15 in the cassette 12 is rotated to feed the ribbon 16 in a direction opposite to the direction F without trouble.

(Prior art and problems to be solved by the invention) Generally, in a thermal transfer printer, heat from a thermal head is transferred to a thermal transfer ribbon, and carbon, etc. on the thermal transfer ribbon is melted and transferred onto printing paper. Printing is then performed. Therefore, if a relative movement occurs between the ribbon and the printing paper during printing, the transferred characters will be in a state of flowing, so it is essential to prevent the relative movement from occurring. Therefore, in a type of printer in which a thermal transfer ribbon cassette is mounted on a metal carriage, the ribbon is sent in the opposite direction at the same speed when the carriage is in use, so that relative movement does not occur. However, with this type of device, if the ribbon is fed during the backward movement of the carriage, a relative movement occurs between the printing paper and the ribbon at twice the moving speed of the carriage, resulting in printing failure during the backward movement. It is possible.

Therefore, in order to perform bidirectional printing, a ribbon cassette is placed at a fixed position on the frame close to the T-carriage, and the ribbon exposed from the ribbon cassette is stretched over the printing range on the printer. A thermal transfer printer that uses a ribbon feed motor also
This has been proposed in the past. However, in this conventional printer, when the carriage on which the print head is mounted is moved to the right or left end of the movement range, the ribbon feed motor transports a predetermined amount of ribbon regardless of whether there is printing or not. There was a problem in that the amount of ribbon used was wasted. Further, in this conventional configuration, since the portion of the ribbon exposed to the outside from the ribbon cassette becomes long, there is also a problem that the ribbon is easily bent and wrinkled.

Now, in this printer, the forward movement direction F of the carriage 5 is
When printing on the
8, the cartridge holder 11 is moved to the lower position,
The upper ribbon cassette 12 is the heat generating part 6a of the print head 6.
In this state, the carriage 5 is moved in the forward direction F by the clockwise rotation of the timing belt 8, and the print head 6 is rotated to the white position.
Thermal transfer printing is performed on the printing paper on the platen 1 via the ribbon 16'i of the upper ribbon cassette 12. During printing in the forward direction, as shown in FIG. 8 transmission gear 40 is meshed with 10,000 intermediate gears 34, and the moving force of the timing belt 8 is transmitted to 10,000 drive shafts 30, so that the winding system/I/15 of the upper ribbon cassette 12 is The ribbon 16 is rotated many times, and the ribbon 16 is moved in a direction opposite to the forward movement direction F of the carriage 5 without any trouble.

Also, when the cartridge set holder 11 is moved to the upper position by the rotation of the operating motor 18 from this forward printing state,
As shown in FIGS. 4 and 5, the lower ribbon cassette 13 is arranged opposite to the heat generating portion 6a of the print head 6. As shown in FIGS. Therefore, in this state, while the carriage 5 is moved to the backward direction hole by the counterclockwise rotation of the timing heald 8, the printing paper is passed through the ribbon 16 of the lower ribbon cassette 13 by the print head 6 at the printing position. is printed.

During printing in the backward direction, the moving force of the timing belt 8 is transmitted to the other drive shaft 31 by the meshing of the third transmission gear 40 and the other intermediate gear 35, as shown in FIG. Therefore, the winding system (v15) of the lower ribbon cassette 13 is rotated, and the ribbon 16 is moved in the direction opposite to the backward movement direction R of the carriage 5 without any trouble.

Furthermore, when changing the traveling direction of the carriage 5 or when the carriage 5 is empty-feeding without printing, the 6th.
As shown in FIG. 7, the recess 6b of the print head 6 is placed in the non-printing position via the actuation member 9 by the operation of the solenoid.

Therefore, the moving force of the timing belt 8 is not transmitted to either of the drive shafts 30.31, and the ribbons 16 of either the upper or lower ribbon cassettes 12.13 are not fed unnecessarily.
