Abstract

PURPOSE:To prevent colors from misregistering, by a method wherein a single heat transfer ribbon is provided with at least three primary colors in plurality and in succession, and a color boundary discriminating part is provided at each boundary part between adjacent colors. CONSTITUTION:The heat transfer color ribbon 1 is provided with yellow (2Y), magenta (2M) and cyan (2C) colors, and the color boundary discriminating part (2D) at each boundary part between adjacent colors. The boundary part is detected by a method of using a photo-sensor (3S), a method wherein aluminum is vapor-deposited on the ribbon and is detected through contact or in a non- contact manner or other method, and driving of a take-up reel of a head carriage is controlled to conduct transfer recording in the primary three colors. Accordingly, maintenance is facilitated because it is necessary only to replace a single ribbon, the accuracy of each of the colors on the ribbon used is not required, and there is no need for considerable allowance of each of the colors for the recording width.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a color transfer device and a ribbon, and is particularly improved so that color fading is eliminated and ribbon length accuracy and margin during recording are no longer required.

Conventionally used devices of this type used three ribbons for each color, yellow (Y), magenta (M), and cyan (C), as shown in Figure 1, which had the disadvantage of causing color misalignment. Ta.

This invention is intended to provide an extremely effective means for eliminating the above-mentioned drawbacks, and has the configuration shown in Figure 2.

Hereinafter, the color transfer device and ribbon according to this invention will be explained with reference to the drawings.

In Figure 2, 1llFi thermal transfer multicolor ribbon,
Yellow (2Y)t Magenta (2M)? and cyan (2C)
A color boundary identification unit (2D) is provided at the boundary between each color. To detect this boundary, there is a method using a photosensor (5B) i as shown in Figure 3, or a method of contact or non-contact detection by vapor depositing aluminum on the ribbon as shown in Figure 4. be.

FIG. 5 shows the relationship between the recording paper (P) and the thermal head (H) in the color transfer device.

The length of each color of the ribbon (R) (B) is the recording width of the recording paper (
) must be longer.

In FIG. 1116, the rotation of the platen +11 is controlled in accordance with a rotation control signal to be described later, and the recording paper +21 is sent out at a predetermined pitch. (3) shows a thermal transfer multicolor ribbon, which is sandwiched between the thermal head 14) and the recording paper (2), and arranged so that the paint side is in contact with the recording paper (2). As this ribbon (3), use the ribbon shown in Fig. 2.

Book f! In IK, the thermal head +41 t is fixed on the head moving table (5).This head moving table (5) is indicated by arrow a.

Make it possible to move in the horizontal direction as shown in bK.

Further, the supply reel (6) supplies the ribbon tube, is in a stopped state when the head moving table 11 is moving in the direction of arrow a, and is in a stopped state when the head moving table (5) is at the left end position.
(It's like playing out 3I. +71 is a ribbon (
3) shows the take-up reel to be taken up after use, and this take-up reel ()) has the head moving table tel taken off to the left, and the color boundary sharp part of the ribbon (3) is on the sensor (8). When detected, the take-up reel +71 comes to a halt and stops winding. Further, +81+91 is an intersecting roller provided on the head moving table +51, which functions to peel off the ribbon (3) and the recording paper (2) after transfer when the head moving table (5) moves in the direction of arrow a. There is.

When the transfer of at least the three primary colors is completed, the platen (1) sends out the recording paper (2) at a predetermined pitch according to a rotation control signal.

Since this example is constructed as described above, at least the three primary colors are transferred to a predetermined pixel of the recording paper (21), so that a desired color can be obtained.

Since the present invention is thermal transfer, ordinary paper can be used as recording paper, and maintenance is easy because it is only necessary to replace one ribbon. Further, there is an advantage that precision in the length of each color of the ribbon used is not required, and there is no need for much margin for the recording width of each color.

In the improved example, the ribbon is supplied in the direction indicated by the arrow, but it is also possible to reverse the positions of the supply reel (61) and the take-up reel (71) and supply the ribbon in the direction indicated by the arrow.

Furthermore, the present invention is not limited to the above-described embodiments, and may of course include various other configurations without departing from the gist of the present invention.
