Abstract

PURPOSE:To miniatuarize a recording device and make color recording of a card and the like easy by applying thermal transfer recoding to a memory unit, fixing a recording medium to a mobile stand and moving the mobile stand relatively to a recording head. CONSTITUTION:A reading system consisting of a three colors light source 3, a condenser lens 4 and a reading sensor 5 is moved to the right by operating a copy start button, and color information of an original 1 on a transparent glass 2 is read successively, and accumulated in a picture image memory 6. Accumulated R, G, B, information from the original 1 is processed by a picture image processing section 7 and converted into three primary colors, cyan C, yellow Y, magenta M, and black KB, and accumulated in a picture image memory 8. Accumulated color information is sent to a thermal head driving circuit 10 and recording in a recording medium 14 on the mobile stand 15 by a thermal head 9 is started. The recording device is miniaturized and color recording of a card and the like is made easy by fixing the recording medium 14 to the mobile stand 15 and relatively moving he mobile stand 15 to the head 9.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical field to which the invention pertains The present invention relates to a color recording device, particularly a color recording device that is compact and easy to handle. (2) Prior art The conventional color recording device Electrophotographic methods have been put into practical use, but because they require development and fixing, they have to be large in size, and when transferring the toner image formed on a photosensitive drum to a recording medium, it is necessary to use only one recording medium. Jams may occur because each piece of paper is moved by the friction of rollers.Furthermore, there is a method to prevent jams by wrapping it around a cylinder and rotating it; It had drawbacks such as being unsuitable for

(3) Purpose of the Invention The purpose of the present invention is to provide a color recording device for cards that is compact and easy to handle.

(4) Structure of the invention (4-1) Differences between the characteristics of the invention and the conventional technology The present invention has the following features:
The most important feature of the recording device is that it uses thermal transfer recording, the recording medium is fixed to a moving table, and the moving table is moved relative to the recording head. The aspects are different.

(4-2) Example FIG. 1 is a diagram illustrating the present invention in detail.

1 is an original to be copied, 2 is a transparent glass, 3 is a light source that can sequentially emit three primary colors, 4 is a condenser lens,
5 is a reading sensor, and 6 is an image memory.

7 is an image processing unit, 8 is an image memory, 9 is a thermal head having a heating element array at the tip, 10 is a drive circuit for the thermal head 9,
11 is a color ink film, 12 is a color ink film roll, 13 is a used empty ink film, - an ink film take-up roll, 14 is a recording medium for obtaining a copy of the original 1, and 15 is a moving table for fixing and moving the recording medium. , 16 are position detection sensors for the color ink film 11.

FIG. 2 shows the structure of a color ink film. 1 Usually, cyan and magenta inks are placed on a thin base film of about 10 to 50 microns as shown in the figure.

In addition to the recording color materials of the three primary colors of yellow, black recording color materials are formed at regular intervals l. Note that black is not necessarily necessary. The color ink is formed to have a width W, and a portion of 1 width d is not coated with color ink, and a position detection mark for detecting the position of the color ink film is formed.

Next, the operation will be explained using FIGS. 1 and 2.

Press the copy start button (not shown) and
Light source 3. Condensing lens 4. The reading system consisting of the reading sensor 5 starts moving to the right and sequentially reads the color information of the color original 1 and stores it in the two-image memory 6. To read color information, set light source 3 to R (red).

The three primary colors of G (green) and B (blue) are emitted in sequence at appropriate intervals, and the two reflected lights are sequentially read by a reading sensor.

The reading sensor is a C
A CD sensor will suffice. That is, the information obtained by applying R light to the original 1 and converting the intensity of the reflected light into an electrical signal is the R information included in the original 1.

The reflected light for G light is C information, and the reflected light for B light is B.
It becomes information. Therefore, color information written on the original 1 can be read by sequentially emitting R, G, and H light to scan the entire original 1 and reading the reflected light. The information from the reading sensor is sequentially accumulated in the image memory 6, and the accumulated information is then sent to the image processing section 7 and R
, G, and B information are recorded in the three primary colors cyan (C) and yellow (
Y), magenta (M), and then black (BK) and stored in the 9-image memory 8. Both 6 and 8 are image memories, but the memory 6 is a buffer memory for matching the operating speed of the image processing section 7 and the reading speed of the reading sensor 5, and does not necessarily require the capacity of one document. I don't. Practically speaking, a few lines are sufficient. On the other hand, the image memory 8 requires a capacity equivalent to one document. That is, as will become clear from the explanation of the primary recording method, this is because one sheet is recorded for each color.

Color information C for one document stored in the image memory 8,
Among M, Y, and BK, C information is first sent to the thermal head drive circuit 10 of the recording section to start recording. When recording is started, the color ink film 11 wound around the color ink film roll 12 is moved to the winding roll 1.
The recording medium 14, which is wound up in the direction of arrow 3 and fixed to the moving stage 15 as shown in FIG. The cyan ink adheres to the medium 14 and is recorded with cyan ink. When the C information has been recorded on the entire surface of the recording medium, the state is as shown in FIG. 3.

Subsequently, the moving table moves in the direction of the arrow (■), returns to the position shown in FIG. 1, and once stops. At this time, in order to record the next M information, the operation of the take-up roll 13 must be controlled so that the magenta portion of the color ink film 11 is located below the thermal head 9. For this purpose, the position detection mark shown in FIG. 2 may be used. There are two types of position detection marks, one for detecting the home position of the color ink film 11 and one for detecting two colors. That is, two consecutive marks are placed every third, but the position where two marks are detected simultaneously by the sensor 16 is the home position and the cyan recording start position. The next three marks are the recording start positions for magenta, yellow, and black in this order. After recording magenta information, a total of four colors, yellow and black, are sequentially recorded to complete the recording of one sheet.

The above is an explanation of the case where one recording medium is placed on the moving stage 15 and recorded, but when the original 1 is to be reduced and recorded, or when the original 1 is resized smaller than the thermal hand 9, the fifth As shown in the figure, it is possible to mount a plurality of recording media and record on the plurality of recording media at once.

(5) As described in detail, according to the present invention, 1. Since the recording medium is fixed on a moving table and recorded on it, it is possible to reliably move even recording media such as cards that are over 200 pm thick and difficult to move by friction using rollers. Not only can this be done, but it also has the advantage of being able to record on multiple recording media at the same time. Further, the means for reading the original may be a television camera or the like.
