Description

Description: TECHNICAL FIELD The present invention relates to a color recording apparatus, and more particularly to a color recording apparatus which is small in size, easy to handle, and capable of recording even thick cards.

(2) Conventional technology Conventionally, a color recording apparatus of an electrophotographic type has been put into practical use, but it needs to be developed and fixed, so that the color recording apparatus needs to be enlarged and a toner image formed on a photosensitive drum is recorded. When the recording medium is transferred to the medium, a jam may occur because the recording medium is moved one by one by the friction of the rollers. Further, as a means for preventing the jam, there is a method of winding the cylinder and rotating it. It has a drawback that it is not suitable for thick and hard recording media such as cards.

(3) Object of the Invention An object of the present invention is to provide a color recording device for cards which is small in size and easy to handle.

(4) Configuration of the Invention (4-1) Differences between Features of the Invention and Conventional Techniques The present invention applies a thermal transfer recording to a recording apparatus, fixes a recording medium on a flat plate-shaped moving table, and moves the table. The main feature is that the lens is moved relative to the recording head,
The moving mode of the recording medium is different from that of the conventional apparatus.

(4-2) Embodiment FIG. 1 is a view for explaining an embodiment of the present invention, in which 1 is a document to be copied, 2 is transparent glass, 3 is a light source capable of sequentially emitting three primary colors, 4 is a condensing lens, 5 is a reading sensor, 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, 1
Reference numeral 0 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 color ink film take-up roll, and 14 is an original document 1.
Is a recording medium for obtaining a copy of the recording medium, 15 is a flat-shaped moving base for fixing and moving the recording medium, and 16 is a position detection sensor for the color ink film 11.

FIG. 2 shows the structure of a color ink film, which is usually a thin base film of about 10 .mu.m to 50 .mu.m. The recording color materials are formed at equal intervals. Black is not always necessary. The color ink is formed to have a width w, the color ink is not applied to the portion having the width d, and a position detection mark for detecting the position of the color ink film is formed.

Next, the operation will be described with reference to FIGS.

While pressing the copy start button (not shown),
The reading system including the light source 3, the condenser lens 4, and 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 image memory 6. To read color information, the light source 3 is made to sequentially emit light in the three primary colors of R (red), G (green), and B (blue) at appropriate intervals, and the reflected light is sequentially read by the reading sensor. The reading sensor may be a CCD sensor normally used for reading a facsimile. That is, the information obtained by applying the R light to the original 1 and converting the intensity of the reflected light into an electric signal is the R information included in the original 1, and the reflected light for the G light is the G information and the reflected light for the B light is the reflected light. Becomes B information. Therefore, the color information written on the original 1 can be read by sequentially emitting R, G, and B lights 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 unit 7 to record the R, G, B information in the three primary colors cyan (C) and yellow (Y). , Magenta (M), and further converted into black (BK) and stored in the image memory 8. Both 6 and 8 are image memories,
The memory 6 is a buffer memory for matching the operating speed of the image processing unit 7 and the reading speed of the reading sensor 5,
The capacity for one document is not always required. A few lines are sufficient for practical use. On the other hand, the image memory 8 is the original 1
The capacity for one sheet is required. That is, this will be made clear by describing the recording method next, because one sheet is recorded for each color.

Color information C for one document stored in the image memory 8,
Of the M, Y and BK, the 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 on the color ink film roll 12 is taken up by the take-up roll 13, and the recording medium 14 fixed to the moving table 15 moves in the arrow direction as shown in FIG. Then, the cyan ink heated by the thermal head 9 is melted according to the C information and adheres to the recording medium 14 to perform recording with the cyan ink. When the C information is recorded on the entire surface of the recording medium, the third
It is in the state shown in the figure.

Subsequently, the movable table moves in the direction of the arrow, returns to the position shown in FIG. 1, and then stands still. At this time, in order to record the next M information, the operation of the take-up roll 13 needs to be controlled so that the magenta portion of the color ink film 11 is below the thermal head 9. For the control for this purpose, the position detection mark shown in FIG. 2 may be used. There are two types of position detection marks for detecting the home position of the color ink film 11 and for detecting the color. That is, although two consecutive marks are provided every three marks, the position where the two marks are simultaneously detected by the sensor 16 is the home position and the cyan recording start position. The next three marks are the recording start positions of magenta, yellow, and black, respectively. After recording the magenta information, a total of four colors, yellow and black, are recorded in order, and the recording of one sheet is completed.

The above description is for the case where one recording medium is placed on the movable table 15 for recording, but when the original 1 is reduced in size for recording, or when the original 1 is smaller than the thermal head 9, the fifth As shown in the figure, it is possible to stack a plurality of recording media and record on a plurality of recording media at a time.

As a means for fixing the recording medium to the moving table, there are means such as suction by vacuum, magnetic, electrostatic, mechanical, by means of an adhesive tape, or means by which a recess having the same shape as the medium is provided. Although not particularly limited, electrostatic means is advantageous in terms of simplicity.

(5) Effects of the Invention As described above, according to the present invention, the recording medium is fixed on the moving table and moved, and recording is performed on the recording medium. Not only is it possible to reliably move even a recording medium that has a thickness exceeding that of the frictional movement by rollers, but it is also possible to perform simultaneous recording on multiple recording media. A device such as a television camera may be used as the means for reading the original.
