Abstract

PURPOSE: To prevent the hue change by dot position deviations of respective colors by providing first, second recording means for recording a recording medium in the state that the medium is rotated at a first rotating angle and a second rotating angle different from the first angle with respect to first and second color inks of an ink sheet from a position perpendicular to the arraying direction of heating generators of a thermal head. CONSTITUTION: After a cyan image is formed on an yellow image and a magenta image of a recording medium 2, a CPU 40 rotates a table (recording medium) 15 deg. in a counterclockwise direction by a motor 25, and sets it perpendicular to the arraying direction of heat generating resistor of a thermal head 4. Accordingly, in the case of a print result shown in (f), the dispositions of three color dots are superposed and displaced. Even if they are deviated in a subscanning direction, it is not apparent. That is, when the three colors of inks are superposed to record color images, at least one color is different in the direction of the recording image from the other color, and screen angles are altered at the colors, thereby eliminating the superposition of the dot positions of the colors.

A recording mechanism 3 for recording data on the recording medium 2 is provided on the upper surface side of the table 1 (in the direction of the supporting surface of the recording medium 2). The recording mechanism 3 includes a thermal print head (hereinafter abbreviated as a thermal head) 4 having a plurality of heating resistors as recording means, an ink sheet 5 as a thermal transfer color material sheet, and a supply roll 6 to which the ink sheet 5 is fed. The ink sheet 5 is wound up by a winding roll 7 as a winding means. The arrangement direction of the plurality of heating resistors of the thermal head 4 is the main scanning direction.

FIG. 3 shows a structure in the vicinity of a recording portion in which the ink on the ink sheet 5 is transferred to the recording medium 2 by the thermal head 4. The winding roll 7 is rotated by a motor 9 connected to the winding shaft 8 and is driven to be wound.

As shown in FIG. 4, the eccentric cam 14 is rotated by the motor 13, and the arm 12 attached to the thermal head 4 is pushed up by the eccentric cam 14 to separate the thermal head 4 from the recording medium 2.

In such a state, the ink sheet 5 is cueed, the recording medium 2 is mounted on the table 1, or after recording a color image, the recording medium 2 is moved to record the next color.

A carriage 17 is movably supported by two guide rails 16 and a ball screw 19 for transmitting rotation from a table moving motor 18 to the carriage 17.

Inside the carriage 17, as shown in FIGS. 6 and 7, a rotating mechanism 20 for the table 1 is provided. The rotating mechanism 20 is connected to the center of the table 1 and rotates with the rotating shaft 2 that rotates with the table 1.
1, a pulley 22 connected to the rotating shaft 21, a belt 24 spanning the pulley 22 and a gear train 23, and a motor 25 for rotating the table 1 that rotates the gear train 23. . The rotation (rotation) of the motor 25 is transmitted to the pulley 2 via the gear train 23 and the belt 24.
By being transmitted to 2, the rotary shaft 21, that is, the table 1 is rotated.

That is, the table 1 or the recording medium 2 is rotated by the rotation of the motor 25. For example, as shown in FIG. 8, the horizontal direction of the recording medium 2 is aligned with the direction perpendicular to the arrangement direction of the heating resistors of the thermal head 4 (a), and the vertical position is 15
The state is set to three position states, that is, a state rotated in the counterclockwise direction (b), a state rotated from the vertical position by 15 degrees, and a state rotated in the clockwise direction (c).

In the case of (a), the recording medium 2 and the table 1 are arranged in parallel with the guide rails 16, 16. That is, first, as shown in FIG. 8A, the table 1 and the recording medium 2 are arranged in a direction parallel to the guide rails 16, 16. In this direction, the recording medium 2 is sub-scanned along the direction of the guide rails 16 and 16,

And the recording medium 2 are rotated to form a magenta image. Further, the table 1 and the recording medium 2 are rotated in the direction shown in FIG. 8C to form a cyan image.

Next, the ink sheet 5 will be described. FIG. 9 shows a plan view of the ink sheet 5. The ink sheet 5 has an ink layer 31 made of a binder such as a colorant and wax having a thickness of 2 μm on a heat-resistant support 30 having a thickness of 3.5 μm such as PET (polyethylene terephthalate resin).
It has a structure in which it is melt-coated so as to have a thickness of m.

The ink layer 31 is a yellow ink layer 31Y,

Black ink that does not transmit light is applied.

FIG. 1 is a block diagram of the control system of the recording apparatus.
Shown in That is, the CP that controls the entire recording device
U40 is provided. This CPU 40 has a bus 4
1, ROM 42, RAM 43, thermal head drive circuit 44, motor drivers 45, 46, 47, 4
8, the color division processing unit 49, and the interface 50 are connected. The ROM 42 has a conversion pattern memory 42a in which a control program is stored and two types of conversion patterns are stored. RA
M43 is used for storing image data to be recorded or for working, and stores, for example, image data obtained by converting the image data to be recorded by the conversion pattern.

The thermal head drive circuit 44 drives the thermal head 4, the motor driver 45 drives the ink sheet winding motor 9 for transporting the ink sheet 5, and the motor driver 46 drives the thermal head 4 on the recording medium. The motor 13 for moving the thermal head for urging / releasing the recording medium 2 is driven, the motor 18 for moving the table 1 for conveying the recording medium 2 is driven by the motor driver 47, and the motor driver 48 records. A motor 25 for rotating the table 1 on which the medium 2 is placed is driven.

The interface 50 includes an external personal computer (personal computer) 51 or a scanner 51.
Is selectively connected to receive the recording code from the external personal computer 51 or the image data from the scanner 51.

The color division processing section 49 uses the interface 5
The image data of R (red), G (green), and B (blue) captured at 0 is converted for each of yellow, magenta, and cyan.

The CPU 40 uses the conversion pattern stored in the conversion pattern memory 42a of the ROM 42 to convert the image data and the density data. For example, the yellow image data and the density data are not converted, and the coordinates for the image data and the density data of each pixel are stored in a matrix as shown in FIG. For magenta image data,
As shown in (b) of 0, the coordinates for the image data and density data of each pixel are changed, and for the cyan image data, as shown in (c) of FIG. The coordinates for the density data are changed. In this case, the same number is the image data and the density data for each color corresponding to the same position.

In this case, it is necessary to put white as the image data and 0 as the density data in the positions not to be recorded. In the case of FIG. 10, the case where the original image data is a 5 × 5 matrix has been described, but in reality, it has data for one screen. That is, in the main scanning direction,
There are several hundreds to several thousands of pixels in both the sub-scanning directions, but this can be dealt with by enlarging the matrix.

It is also possible to deal with a large number of pixels by combining the matrices of FIG. 10B. FIG. 10D is a combination of FIG. 10B and 4
It is the figure which combined two matrices. It can be seen that by increasing the number of matrices, it is possible to convert even the number of pixels of several hundreds to several thousands. However, although the density data is lost from the pixel A in the diagram of FIG. 10D, the data of the pixel surrounded by, for example, can be stored.

Thus, the image data can be processed so that the cyan and magenta image data overlaps with the rotated image area of the yellow image. Next, the recording operation of this recording apparatus will be described.

First, the image data of R (red), G (green), and B (blue) captured by the interface 50 is converted into yellow, magenta, and cyan by the color division processing section 49, and the yellow is stored in the RAM 43. , Cyan, and magenta image data are transferred and stored.
Then, the CPU 40 uses the conversion pattern stored in the conversion pattern memory 42a of the ROM 42 to store the RAM in the RAM.
The cyan image data stored in 43 is converted to the position corresponding to the case rotated by 15 degrees clockwise, and the magenta image data is converted to the position corresponding to the case rotated counterclockwise by 15 degrees. , Are stored again in the RAM 43.

The recording medium 2 is mounted on the table 1. Then, a recording start signal is output from the CPU 40, and the ink sheet 5 is simultaneously conveyed by the driving of the motor 9,
The cueing of the ink sheet 5 is performed. At this time the sensor 1
When 0 detects a mark 32 having a width of 5 mm, it sends a position detection signal to the CPU 40.

Next, from the CPU 40 to the motor driver 4
The motor 9 is stopped by the signal to 5, and the cueing of the ink sheet 5 is completed. Next, the thermal head 4 is the CPU 4
Motor 13 according to signal from 0 to motor driver 46
Is pressed toward the recording medium 2 to bring the ink sheet 5 into contact with the recording medium 2.

Next, printing is performed in the order of yellow, magenta, and cyan, and the series of operations for recording the four colors is as follows. First, a yellow image is formed, but C
The motor 40 is driven by the PU 40 via the motor driver 47, and the table 1 is moved to convey the recording medium 2 at a desired recording speed in the direction of arrow A in FIG. In synchronization with this, the ink sheet 5 is conveyed by driving the motor 9. Further, in synchronization with these, the thermal head 4 outputs the yellow image data stored in the RAM 43 to the thermal head drive circuit 44. The heat generating resistor driven by the thermal head drive circuit 44 heats the ink sheet 5 to melt the yellow ink layer 31Y of the ink layer 31, and a yellow image is formed on the recording medium 2.

In this case, as shown in FIG. 8A, the state in which the recording medium 2 and the table 1 are aligned with each other in the direction perpendicular to the arrangement direction of the heating resistors of the thermal head 4,
A yellow image is printed as shown in FIG. 11A in a state in which the guide rails 16 and 16 are arranged parallel to each other. The horizontal direction and the vertical direction of this yellow image correspond to the horizontal direction and the vertical direction of the recording medium 2, respectively.

In the case of FIG. 11A, the right direction is the main scanning direction (arrangement direction of the heating resistors of the thermal head 4), and the upper direction is the sub scanning direction (conveying direction of the recording medium 2). Then, the thermal head 4 for the yellow image data
When the recording by is completed, the CPU 40 separates the thermal head 4 from the recording medium 2 by the motor 13, rotates the motor 18 in the opposite direction to the recording, and returns the table 1 to the recording start position of the thermal head 4.

Further, the CPU 40 causes the motor 25 to move the table 1 (recording medium 2), as shown in FIG.
The thermal head 4 is set in a state of being rotated by 15 degrees counterclockwise from the direction perpendicular to the arrangement direction of the heating resistors. At this time, the yellow image printed on the recording medium 1 is as shown in FIG.
As shown in (b) of FIG. 6, the guide rails 16 and 16 are rotated counterclockwise by 15 degrees from a direction parallel to the guide rails 16.

Next, the CPU 18 drives the motor 18 via the motor driver 47, and the table 1 moves to convey the recording medium 2 at the desired recording speed in the direction of arrow A in FIG. In synchronization with this, the ink sheet 5 is conveyed by driving the motor 9. Further, in synchronization with these, the thermal head 4 outputs the converted magenta image data stored in the RAM 43 to the thermal head drive circuit 44. This thermal head drive circuit 4
The ink sheet 5 is heated by the heat generating resistor driven by 4, the magenta ink layer 31M of the ink layer 31 is melted, and a magenta image is formed on the yellow image of the recording medium 2.

In this case, as shown in FIG. 8B, the recording medium 2 is rotated by 15 degrees counterclockwise from the direction perpendicular to the arrangement direction of the heating resistors of the thermal head 4.
Then, with the table 1 rotated counterclockwise by 15 degrees from the direction parallel to the guide rails 16 and 16, as shown in FIG. 11C, the magenta image is printed on the yellow image. The horizontal and vertical directions of this magenta image correspond to the state in which the recording medium 2 is rotated counterclockwise by 15 degrees from the horizontal and vertical directions, respectively.

When the recording of the magenta image data by the thermal head 4 is completed, the CPU 40 causes the motor 13 to separate the thermal head 4 from the recording medium 2 and causes the motor 18 to rotate in the opposite direction to that at the time of recording, so that the table 1 is moved. Return to the recording start position of the thermal head 4.

Further, the CPU 40 causes the motor 25 to move the table 1 (recording medium 2), as shown in FIG.
The thermal head 4 is set in a state of being rotated by 15 degrees in the clockwise direction from the direction perpendicular to the arrangement direction of the heating resistors (rotation by 30 degrees). At this time, as shown in (d) of FIG. 11, the yellow image and the magenta image printed on the recording medium 1 are moved in the clockwise direction from the direction parallel to the guide rails 16 and 16.
It is rotated in a state of being rotated once.

Next, the CPU 18 drives the motor 18 via the motor driver 47, and the table 1 moves to convey the recording medium 2 at a desired recording speed in the direction of arrow A in FIG. In synchronization with this, the ink sheet 5 is conveyed by driving the motor 9. Further, in synchronization with these, the thermal head 4 outputs the converted cyan image data stored in the RAM 43 to the thermal head drive circuit 44. This thermal head drive circuit 44
The ink sheet 5 is heated by the heating resistor driven by, and the cyan ink layer 31C of the ink layer 31 is melted,
A cyan image is formed on the yellow image and the magenta image on the recording medium 2.

In this case, as shown in FIG. 8C, the state in which the recording medium 2 and the table 1 are rotated by 15 degrees in the clockwise direction from the direction perpendicular to the arrangement direction of the heating resistors of the thermal head 4, As shown in FIG. 11E, the cyan image is printed on the yellow image and the magenta image in the state of being rotated by 15 degrees clockwise from the direction parallel to the guide rails 16, 16. The horizontal direction and the vertical direction of this cyan image correspond to the state in which the recording medium 2 is rotated 15 degrees clockwise from the horizontal direction and the vertical direction, respectively.

After that, the CPU 40 rotates the table 1 (recording medium 2) by 15 degrees counterclockwise by the motor 25, and as shown in FIG. 11 (f), the direction in which the heating resistors of the thermal head 4 are arranged. Set to the direction perpendicular to (return to the original position).

Therefore, in the case of the print result shown in FIG. 11 (f), the arrangement of the dots of the three colors may be misaligned in some sub-scanning directions with some overlapping or misaligned dots. Also, it has become inconspicuous.

As described above, when a color image is recorded by superposing three color inks in the recording apparatus of the fusion type thermal transfer recording system, at least one color has a thermal head and the recorded image is oriented in the other direction. By changing the recording (changing the angle of the recording medium with respect to the conveying direction), that is, changing the screen angle for each color, the positions of the dots for each color do not necessarily overlap.

Therefore, even if the dot position deviates from a predetermined position due to fluctuations in the transport speed of the recording medium or vibrations of the apparatus, the hue of the image does not greatly change. That is, by changing the dot position to be recorded for each color, there is no color shift during color recording.

The rotation angle can be changed by changing the shape of the matrix. Further, in the above-described embodiment, the case where the ink sheet has three colors of yellow, magenta, and cyan has been described, but the same can be performed when the ink sheet has four colors of yellow, magenta, cyan, and black.

In this case, as shown in FIG. 12, the ink sheet is coated with the black ink layer 31B after the cyan ink layer 31C on the ink layer 31. Further, the color division processing unit 49 shown in FIG. 1 converts the image data of R (red), G (green), and B (blue) captured by the interface 50 into image data of yellow, magenta, cyan, and black. And they are RAM43
Memorized in. In addition, as the recording operation, in the state shown in FIG. 11F after the recording of cyan (the recording medium 2 and the table 1 are arranged in a direction parallel to the guide rails 16 and 16), black recording is performed. Will be recorded.

As described above in detail, according to the present invention,
When recording is performed on a recording medium that is moved in a direction orthogonal to the arrangement direction of the heating elements of the thermal head using an ink sheet composed of a plurality of colors of ink, due to fluctuations in the conveying speed of the recording medium, vibration, etc., It is possible to provide the recording apparatus in which the hue of the image does not largely change even if the position of the dot for each color deviates from the predetermined position.
