Description

DETAILED DESCRIPTION OF THE INVENTION The present invention regulates the feeding of a thermal transfer tape in a transfer type thermal recording device in the feeding direction of printing paper or in a direction oblique to the feeding direction, and ) in an arbitrary plural number.

Therefore, this type of transfer type thermal recording device in the past was T.
SS terminal 1 This terminal is used in word processors, ticket issuing machines, etc., and in recent years, thermal heads have become denser and faster, and attempts have been made to apply them to color printing.

However, as a transfer type color thermal recording system, the reels (1) and (1) are fed perpendicularly to the feeding direction as shown in FIG.
Using a tape (3) coated with three transfer colors of M) and cyan (C) in three strips facing the feeding direction, the thermal head (4) records three separate colors every three lines. In this method, when mixing colors, the printing paper is fed in the feeding direction by the color minus the line width and is coated sequentially in the order of cyan (C), magenta (M), and yellow (Y). This requires a particularly high level of precision in feeding the printing paper, and it takes a long time to print because a mixture of three colors cannot be produced unless the printing paper advances by three lines.

In addition, the method shown in Fig. 5, that is, yellow (Y) magenta (
In this method, the thermal head (4) is scanned in the lateral direction for each line to record one color at a time using tape (applied in a stepwise manner to the transfer medium). In this case, the thermal head must be operated three times for each color, similar to the method using tape with three strips coated with three colors, and it has been pointed out that the printing speed is slow, and it is difficult to switch between 1-down movement. This required tape winding at line breaks.

Furthermore, in the conventional example shown in Fig. 6, tapes of each color (3
) 3 sets are arranged perpendicularly to the feeding direction of the printing paper,
Each has a thermal head (4) and three sets of tape (
3) and a thermal head (4) that perform horizontal scanning sequentially, the tape must be switched for each hend, making the device itself large and slow. Met.

Furthermore, if the recording speed is to be improved by increasing the speed of the thermal head, it is necessary to improve heat storage compensation technology that focuses on each heating element of the thermal head.

Next, the conventional example shown in Fig. 7 is a three-head system in which printing paper (2) is fed by the rotation of a drum (5), but it has the disadvantages of being large and expensive. In addition, the signals received in line sequential order are stored in a buffer memory, or are stored in a screen memory with multiplied signal times, and the head spacing is made narrower by recording with delayed color sequential signals for each head spacing. That was the issue.

The present invention was devised especially in view of the disadvantages of the prior art, and its main purpose is to make it possible to reproduce multiple colors by subtractive color mixture by one traverse scan of the thermal head. At the same time, we aim to dramatically increase printing volume.
It was designed to be a seven-noh play.

Another main object of the present invention is to minimize the waste of transfer media and to reduce printing costs.

Furthermore, one of the other main objects of the present invention is to dramatically increase the required printing speed per sheet of printed material compared to the conventional method.

On the other hand, the present invention aims to achieve appropriate and appropriate effects on the various physical properties, and the gist of the structure is to regulate the operation perpendicular to the feeding direction of the printing paper that is adjusted and moved in a predetermined direction. In a configuration consisting of a thermal transfer tape that is sequentially supplied between the thermal transfer tape and the thermal transfer tape that is sequentially supplied between the thermal transfer tape that is
A plurality of arbitrary thermal heads are arranged at predetermined intervals on the base line, and the thermal heads are connected to each other, so that the thermal head is moved in a direction perpendicular to the printing paper transport direction ( At the same time, one sheet of thermal transfer tape is separated for each thermal head from a storage reel in which the same number of thermal transfer tapes as the number of thermal heads are wound up and stored. The thermal transfer tape separated by one f1 is placed at a point where the feeding is regulated in the feeding direction of the printing paper or in a direction diagonal to the feeding direction, Considerable design changes are planned.

Hereinafter, a typical embodiment of the present invention will be described with reference to the drawings. Three thermal paper reciprocating in a direction perpendicular to the feeding direction of the printing paper (2) and maintaining a predetermined interval from each other. In order to arrange Hen I・(4)a, (4)b, and (4)c on the operating baseline, the fixed rod (6) is appropriately coated with IL, and the current line is applied to the printing surface of the printing paper (2). Thermal transfer tape (3)a, (3)b, which has four strips of different transfer colors arranged in parallel in the feeding direction.
(3) Stack three sheets of C and wind them onto a set of reels consisting of a storage reel (1) a and a take-up reel (1) b, and then wrap the respective thermal hens l'' (4) a, (4) b, (4) Between C and the printing paper (2), place separate thermal transfer tapes (3) a, (3) b, and (3) C in the feeding direction of the printing paper (2) or It is interposed so as to restrict the feed in a direction oblique to the feed direction.

In addition, the thermal transfer tapes (3)a, (3)b, (3)C
is from the storage reel (1') a to the thermal head (4) a.
, (4)b, (4)C, there is a separation roller (
(not shown) and other mechanisms (thereby separated and transferred to the thermal
(4) a.

The used tapes that have passed through (4)b and (4)C are converged and transferred to the take-up reel (1)b as a three-ply tape. The fixed front (6) has both ends fixed to the device case (7), and the reel (1) a,
(1) It is designed to be reciprocated integrally with b in a direction perpendicular to the feeding direction of the printing paper (2).

Furthermore, each of the two thermal heads (4) has a head portion (
Four tapes 4) are arranged on the operating base line, and one color is brought into contact with each color of the tape (3).

The present invention has a characteristic configuration in which the printing paper is moved in a predetermined direction, and a thermal land whose operation is regulated perpendicular to the direction of the printing paper transport force. In this configuration, which consists of a thermal head and a thermal tape that is sequentially supplied between the printing paper, an arbitrary plurality of thermal heads are arranged at required intervals on the same base line perpendicular to the transport direction of the printing paper. and the thermal heads are connected to each other so that the thermal head can be reciprocated in a direction perpendicular to the direction of force for conveying the printing paper to the printing paper, and the number of the thermal heads is equal to 11.
41 t) Separate and supply the thermal transfer tape one sheet at a time to each surfer head from a storage reel that winds up and stores several sheets of thermal transfer tape, and separates the thermal transfer tape. By regulating the printing paper in the feeding direction of the printing paper or in a direction diagonal to the feeding direction, the defects of the prior art described above can be effectively corrected, and the following specific effects are achieved. This is what I was able to play. That is, in the present invention, the thermal transfer tape (3) is interposed between the thermal head (4) and the printing paper (2) in the feeding direction of the printing paper (2) or in the oblique direction. This makes it possible to reproduce mixed colors by subtractive color mixing with a single horizontal scan of the thermal head, and also allows printing M, (
2) It enables simultaneous color printing to multiple locations, dramatically increasing the amount of printing.

Furthermore, in the present invention, due to the characteristics of thermal transfer recording, wastage of thermal transfer tape can be prevented as much as possible.

That is, since the head section (4) of the thermal head is positioned to transfer each color of the thermal transfer tape with ink of different transfer colors applied to arbitrary plurality of strips, each color is simultaneously transferred to the printing paper (2).
Since it has become possible to transfer to rrJ, the play of the transfer ink as in the past has been reduced.

Furthermore, in the present invention, thermal heads (4)a, (4)
By making the intervals between b and (4) C freely adjustable, printing on any position on the printing paper (2) can be adjusted.

Next, in the present invention, by supplying transfer tapes of different colors to each thermal head,
In the same way as transferring multiple colors onto a single piece of tape, it has the ability to transfer multiple colors, making it possible to create mixed colors.

As stated in Section 1-1, one object of the present invention is to provide a novel and effective transfer type color thermal recording apparatus.
