Abstract

PURPOSE:To eliminate the need to replace a transfer paper at the time of switching from monochromic recording to color recording or vice versa and obtain an inexpensive transfer device without increasing the number of recording heads, by providing a transfer paper comprising a single black ink layer and a transfer paper comprising ink layers of a plurality of colors other than black. CONSTITUTION:The monochromic recording or color recording is selected prior to printing. Where a transfer paper 4a comprises a black ink layer, when a monochromic printing signal is inputted, a recording head 1a is pressed against a drum 2 through the transfer paper 4a and the recording paper 3, thereby printing. During the monochromic printing, a color transfer paper 4b remains stationary, and a recording head 1b for color printing is separated from the drum 2. On the other hand, when a color printing signal is inputted and the paper 3 comes to the position of the head 1b, the head 1b is pressed against the drum 2 through the color transfer paper 4b and the recording paper 3, thereby printing. Accordingly, recording can be easily performed without requiring replacement of a transfer paper. In addition, it is unnecessary to provide a multiplicity of recording heads or position detecting means, and low cost can be maintained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a transfer recording device that is low-noise and easy to colorize as an information output device such as a personal computer, a word processor, etc. or a read copy of a CRT display. 2. Description of the Related Art Conventionally, this type of transfer recording apparatus is disclosed in Japanese Patent Application Laid-open No. 57-45, for example.
As shown in Japanese Patent Publication No. 072, a thermal transfer recording device uses a transfer paper with an ink layer divided into a plurality of color bands and performs color recording using a thermal head as a recording head, and Japanese Patent Application Laid-Open No. 57-69065 As shown in Figure 1, a thermal transfer recording apparatus has been proposed in which ink layers of a plurality of colors are each used as transfer paper of a single color, and a thermal head is installed to perform color recording in correspondence with the transfer paper of each tone.

Problems that the invention aims to solve However, in general, monochrome (black printing) is more common than color recording.
It is often recorded in JP-A-57-45072.
In the configuration as shown in Japanese Patent Application Laid-Open No. 182488, the transfer paper must be replaced to switch between monochrome recording and color recording. It is necessary to add a layer of ink. However, in the former case, there is a problem in that troubles are likely to occur during handling when replacing the transfer paper due to the frequency of replacement and because the transfer paper is generally thin. Furthermore, in the latter case, when monochrome printing is performed, ink layers other than the black ink layer are sent unused and wasted, resulting in an increase in running costs. On the other hand, in the configuration as disclosed in Japanese Patent Application Laid-Open No. 57-182488, a thermal head of the recording head is used for each ink layer.
There was a problem that the cost of the device was high.

Therefore, the present invention eliminates the need for replacement during monochrome recording and color recording, and makes it possible to perform monochrome and color recording without unnecessarily increasing the number of recording heads.

Means for solving the problems and the method of the present invention for solving the above problems are provided with a transfer paper consisting of a single black ink layer and a transfer paper having ink layers consisting of multiple colors other than black. 〇 Effect With this method, in the case of monochrome recording, a black transfer paper sound is used, and in the case of color recording, the other transfer paper having ink layers of multiple colors is used, so that it is easy to use when switching between monochrome and color recording. The present invention provides a low-cost transfer device that eliminates the need to replace transfer paper and has two or less recording heads.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In Fig. 1, la and 1b are recording heads, and generally a thermal head is used. 02 is a drum, and the recording paper 3 is clamped at the leading end (-9 is clamped and wound around the outer circumference of the drum 2. 04a.

4b is a transfer paper, and one is formed of only a black ink layer.
, the other is one in which at least three color ink layers of Y, M, and C (yellow, magenta, and cyan) are coated surface-sequentially (hereinafter referred to as color transfer paper).

sa, sb are supply rolls of transfer paper + a, 4b, 6a,
6b is a winding roll 07 is transfer paper 4a, 4b
The operation of the guide member 8, which is a conveying roller for the transfer sheets 4a and 4b, will be explained based on the constituent sounds of 0 or more. For example, if monochrome or color is selected before printing, the recording paper 3 is conveyed to the drum 2 by a recording paper conveying means (not shown) in response to a print signal input, and the leading edge of the recording paper 3 is clamped by a clamper 9. . -' When the recording paper 3 is clamped, the drum 2 rotates in the direction of the arrow in the figure while winding the recording paper 3 around the outer periphery of the drum 2 by a driving means such as a motor. Now, assuming that a monochrome print signal is input and the transfer paper 4a is a transfer paper made of a black ink layer, the recording head 1a is pressed against the drum 2 via the transfer paper 4a and the recording paper 3, and n printing is performed. It will be done. At this time, the transfer paper 4a is conveyed in the direction of the arrow in the figure by the conveyance roller 8 at a speed corresponding to the rotational speed of the drum 20, and is wound around the take-up roll 6a. At this time, the driving of the drum 2 and the conveyance and winding of the transfer paper 4a may be performed by the same driving source.

Further, during monochrome printing, the color transfer paper 4bFi stops, and the recording head 1b for color printing is separated from the drum 2. When zero recording is completed, the clamp of the recording paper 3 is released and the recording paper is ejected.

On the other hand, when a color print signal is input, the recording paper 3 is clamped to the drum 2 by the clamper 9 as in the case of monochrome printing, and the recording paper 3 is wound on the outer circumference of the drum while the drum 2 rotates in the direction of the arrow in the figure. While rotating it, it comes to the position of the recording head 1b. Furthermore, by the time the recording paper 3 reaches this position, the first color ink layer of the color transfer paper 4b has been set at the position of the recording head 1b. When the recording paper 3 comes to the position of the recording head 16, the recording head 1b is pressed against the drum 2 via the color transfer paper 4b and the recording paper 3, and printing is performed in the direction of the arrow in the figure.When the printing of the n011th color is completed, the same process continues. Then, printing of the second and third colors is performed, and when the printing of the three colors is completed, the recording paper 3 is unclamped and ejected. At this time, the color transfer paper 4b is wound onto the take-up roll 6b by the conveying roller 8 as in the case of monochrome recording.

As a result, by having the monochrome transfer paper 4a and the color transfer paper 4b in the device, and by selecting monochrome and color recording in advance, recording can be easily performed without the need to replace the transfer paper. I can do it. In addition, by controlling the printing start position of the recording paper 3, for example, JP-A-57-1
Low cost can be expected without providing a large number of recording heads and position detection means as shown in Japanese Patent No. 82488.

In this embodiment, the transfer paper and the recording head are arranged on the drum, but instead of the drum, a small-diameter platen roller is used as shown in Figure 2, and the monochrome printing section and the color printing section are placed on a straight line of the recording paper conveyance system. In the case of monochrome printing, printing is carried out in the direction indicated by the arrow n in the figure by the distributed paper conveyance roller 1o, and the printed recording paper 3 is discharged in the direction 12. On the other hand, in the case of color printing, the recording paper 3 passes through the distribution paper conveyance roller 10 and is moved to the direction shown by the arrows B and C in the figure by the conveyance roller 11.
It is transported back and forth in the direction corresponding to each color of the color transfer m4b.
Ru. 13 indicates the return state of the recording paper after printing each color. 0 After the completion of the 3 colors, the recording paper is discharged in the direction of 14. The same effect can be obtained in such a case.

Effects of the Invention The present invention enables easy switching between monochrome recording and color recording by providing a transfer paper made of a black ink layer for monochrome printing and a transfer paper made of ink layers of multiple colors for color printing. .
