Abstract

PURPOSE:To enable plural times of color duplications on the surface of the same transfer sheet, in a color transfer sheet used in a line printer, by making color arrangement symmetric in a predetermined region. CONSTITUTION:A transfer sheet 1 consists of a color track 1, an upper track 2 and a lower track 3 and, when a ribbon A moves to the right direction, color arrangement is performed in the order of Y1, M1, C1, C2, M2, Y2 from a home position 2A and, when moves to the left direction, color arrangement is performed in the order of Y2, M2, C2, C1, M1, Y1 from a home position 3A. The transfer sheet 10 is wound around a paper tube 11 (or 12) in a roll form and the paper tube 11 extrudes asymmetrically from roll end surfaces 10A, 10B and, by this structure, an ink surface 10' is prevented from being set to the side of a head 14. Further, the paper tubes 11, 12 can be set to a cassette in point symmetry and, only by reversely setting the taken-up roll to the cassette, recording to positive and reverse directions is enabled. Color recording can be performed plural times by using the surface of the same transfer sheet.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a color transfer sheet and a transfer sheet roll used in thermal transfer or impact line printers.

Techniques for widening the ribbon width and using the front and back sides of the ribbon for ribbons (sheets) used in printers are disclosed, for example, in JP-A-54-76322 and JP-A-57.
Although it is known from Japanese Patent No. 59795, etc., at that time, it was still a solid black ribbon, and therefore, the above-mentioned publication does not disclose a color ribbon. Recently, color ribbons have been proposed, but conventional color ribbons include yellow (Y), magenta (M), cyan (C), yellow (Y), magenta (M), and cyan (C).

By repeating , that is, repeating YMC, it is possible to print only in one direction, and in the opposite direction, the order is CMYCMY, which has the disadvantage of complicating color designation control.

The present invention has been made in order to solve the above-mentioned drawbacks of conventional color ribbons, and in particular, it provides a color transfer sheet that can be used multiple times on the same transfer sheet surface in a line-type color transfer printer, and a color transfer sheet therefor that can be used multiple times on the same transfer sheet surface. The purpose of this invention is to provide a transfer sheet roll for the following purposes.

1. In order to achieve the above object, the present invention requires that a color transfer sheet used in a line printer has a symmetrical color arrangement within a predetermined section, or that the transfer sheet has a paper tube wound in a roll. , the paper tube protrudes asymmetrically from the roll end surface, or the paper tube includes a first paper tube around which the transfer sheet is wound and a second paper tube around which the transfer sheet is wound; It is characterized in that the first and second paper tubes protrude asymmetrically from the end face of the roll, and both paper tubes can be set in a cassette point-symmetrically. Hereinafter, the present invention will be explained based on examples.

FIG. 1 is a diagram for explaining an example of a color ribbon (transfer sheet) according to the present invention, and FIG. 1 (A) shows Y, M, C
, C, M, Y type color ribbon, Figure 1 (B) is Y, M
, C, and M type color ribbons are shown below, and hereinafter, the left side ■ in the figure is the supply side, and the right side ■ is the winding side. In Figure 1,
IO is a transfer sheet, and the transfer sheet 10 has color tracks 1. Upper track 2. The ribbon consists of a lower track 3, and the upper track 2 is provided with a home position mark 2A, and the lower track 3 is provided with a home position mark 3A as shown in the diagram.
When the ribbon moves to the right in the figure, y,,M, from home position 2A.

CL, C2, M2. The colors are arranged in the order of Y2, and when moving to the left, Y from the home position mark 3A.
2. M2. C2, C,, M8. The colors are arranged in the order of Yl. In addition, in the ribbon shown in FIG. 1(B), when the ribbon moves to the right, Y from the home position mark 2A.

The colors are arranged in the order of M, C, M, and even when moving to the left, the home position mark 3A, Y, Y.

The colors are arranged in the order of M, C, M.

Next, the procedure for transferring using the color ribbon shown in FIG. 1(A) will be explained.

(1) Detects the home position mark 2A of the upper track and waits.

(2), without sub-scanning the transfer sheet to the right,
Recorded in , Ml, and CI.

(3) When recording is completed, send the transfer sheet C2, M2, Y2 (no recording at this time).

(4) Detects the home position mark of the primary upper track and waits.

(5) Yl by repeating the above (1) to (4).

Complete the first use of MX and C1.

(6) Reverse the transfer sheet between the supply side and the take-up side (operator operation).

(7) Detects the home position mark 3A of the lower track and waits.

(8) While feeding the transfer sheet to the left by the sub-operation,
2. M2. Recorded with C2.

(9) When recording is completed, send the transfer sheet as C1, M, Y (do not record at this time).

(10), Home position mark 3 of the next lower track
Detect A and wait.

(11), Y2+ by repeating the above (7) to (10)
M2. Completed using C2 for the first time.

(12) As above, reverse the supply side and take-up side.

(13) Repeat the same operations as (1) to (4) above.

(14), Yl, Ml by repeating the above (13).

Completed using C1 for the second time.

(15) As above, reverse the supply side and take-up side.

(16), by repeating the above (11), Y2. M2゜C2
The second time I used it completely.

(17) The above operation is repeated multiple times.

In the case of the transfer sheet shown in FIG. 1(B), the sheet is fed by Y before detecting the home position mark.

FIG. 2 is a diagram for explaining a transfer sheet roll suitable for use in the above-mentioned transfer sheet. FIG. 2 (A) is a front view, and FIG. 2 (B) is a side view. , 10 is a transfer sheet as described above; 11 is a paper tube on the supply side; 12 is a paper tube on the winding side; and 13 is a platen.

14 is a head, and the 10° side of the transfer sheet 10 is the ink surface. The transfer sheet 1-10 is wound around a paper tube 11 (or 12), and the paper tube 11 (or 12) protrudes asymmetrically from the roll end surface 10A, IOB.
This prevents the ink surface 10' from being deposited on the head 14 side. In addition, the paper tubes 11 and 12 can be set point-symmetrically in the cassette, making it possible to record in the forward and reverse directions as described above simply by setting the wound roll in the cassette in reverse. , and allows set FM production to be performed easily.

Figures 3 and 4 are diagrams for explaining the above-mentioned cent operation. Figure (A) is a front view of the recording unit,
B) is a side view, and FIG. 3 shows a state in which recording has been completed from the state shown in FIG. 2 and the sheet 10 has been wound onto the winding paper tube 12. In this state, transfer the paper tubes 11 and 12 to the transfer sheet 10.
If the paper tubes 11 and 12 are removed from each cassette and the positions of the paper tubes 11 and 12 are swapped, the result will be as shown in FIG. 4, thereby making it possible to perform color recording as described above. It should be noted that it is easy to understand that the paper tube described in FIGS. 2 to 4 is not limited to color transfer sheets, but can also be used for monochrome transfer sheets.

As is clear from the above description, when a color ribbon is used in the present invention, color recording can be performed multiple times using the same transfer sheet surface. Furthermore, when the paper tube according to the present invention is used, since the paper tube protrudes asymmetrically from the roll end surface, it prevents the ink surface from being set on the head side, and prevents ink from adhering to the thermal head due to missetting. can be prevented. Furthermore, since the paper core on the supply side and the paper core on the winding side are configured to be point symmetrical, the rolled up roll can simply be set in the opposite direction (therefore, the rolled up There are advantages such as very easy rerolling operation.
