[0006]

In a thermal transfer recording apparatus using an intermediate sheet, an intermediate sheet having a dyeing layer on which a coloring material is fused is used in melting type thermal transfer recording, and a dye is used in sublimation type thermal transfer recording. An intermediate sheet having a dyeing layer for dyeing is required. The intermediate sheet is stretched between the pair of roll portions, and is drawn out from one roll portion and wound around the other roll portion to be moved. The image is formed on the image receiving body by forming an image on the dyeing layer on the intermediate sheet and then transferring the image-formed dyeing layer and the image receiving body in an overlapping manner. It is formed by separating the image receiving body and the sheet base material of the intermediate sheet, and then fixing if necessary. Further, in order to form a color image composed of a plurality of colors, each color is recorded on the dyeing layer of the intermediate sheet,
The second color and the third color are sequentially superimposed and recorded on the image of the first color. If the misregistration of the color overlap becomes large, the color reproducibility becomes poor and the characters may be blurred. Therefore, an adhesive layer is provided on at least one of the surfaces where the platen and the intermediate sheet are in contact with each other, and the intermediate sheet is caused to run by the adhesive force of the adhesive layer, so that good color registration with less misregistration is achieved. -A method is being considered in which a recorded image can be obtained.

However, after the dyeing layer on which the color image is formed is transferred to the image receiver, in order to stably separate the image receiver and the base material of the intermediate sheet, a pair of rollers is used. It was necessary to increase the tension of the intermediate sheet stretched between the cables. Therefore, the moved intermediate sheet is held by the adhesive platen in a stretched state to record an image, and an image expanded or contracted depending on the magnitude of the tension of the intermediate sheet at the time of subsequent transfer is obtained. However, there is a problem in that a large amount of color misregistration occurs.

After transfer, the image receptor is separated from the intermediate sheet, and the smoothness of the surface of the dyeing layer of the color image transferred onto the image receptor is determined by the surface of the intermediate sheet substrate on the separated side. The surface of the intermediate sheet substrate has almost the same smoothness as the state, and a color image with high glossiness is obtained. In order to reduce the glossiness, a pair of rollers are provided at the downstream position of the separating means and fixing is performed by heating and pressurizing, so that the recording apparatus becomes large and the temperature inside the recording apparatus rises, and the image is increased. This has caused a deterioration in quality.

Further, after an image is formed on the dyeing layer on the intermediate sheet, the dyeing layer on which the image is formed and the image receiving material are superposed and transferred by heating and pressurizing. It was difficult for the transferability between layers to perform good transfer depending on the type of image receptor.

In view of the above points, the present invention is capable of stably separating the image receptor from the intermediate sheet after transfer in a thermal transfer recording apparatus using the intermediate sheet, and at the same time, image expansion and contraction and color superposition. It is an object of the present invention to provide a color image recording apparatus capable of obtaining a good color image with less positional deviation.

Another object of the present invention is to provide a color image recording apparatus capable of obtaining an image having a low glossiness by a simple method.

Still another object of the present invention is to provide a color image recording apparatus capable of stably transferring an image on an intermediate sheet onto a desired image receiving body.

[0013]

To achieve this object, a color image recording apparatus of the present invention comprises an intermediate sheet having a light-transmitting dyeing layer on one surface of a continuous sheet-like substrate. A sheet, a sheet holder that is detachable from the recording position and holds the other surface of the intermediate sheet, and the sheet with the intermediate sheet held by the sheet holder. A recording means for selectively recording the ink material on the dyeing layer, and the dyeing layer of the intermediate sheet together with the surface of the intermediate sheet on which the ink material is recorded and the image receptor are in contact with each other. The intermediate sheet
A transfer means for transferring the ink material recorded on the sheet to the image receiving body by a medium of heat and pressure, and a separating means for separating the image receiving body from the intermediate sheet after the transfer, and the intermediate sheet The sheet is stretched between the intermediate sheet supply roll for winding the unused portion and the intermediate sheet take-up roll for winding the used portion, and the winding force of the intermediate sheet take-up roll. It is configured by providing a winding force varying means for varying the winding force to a predetermined value.

The intermediate sheet is an intermediate sheet that winds an unused portion.
Intermediate sheet winding roll for winding the supply roll and used part
The winding force of the intermediate sheet winding roll or the intermediate sheet supplying roll is set by the winding force control means, and the winding force is set in the winding force control means. With respect to the driving rotation of the above, the both rolls are rotated through the speed reducing means.

Further, the transfer means has a heating body and a pressure roller whose surface is covered with a rubber layer, so that the image receiving surface on which the image is formed is in contact with the pressure roller. The sheet is re-fed, and the image on the image receptor is fixed by heating and pressurizing the transfer means.

Further, the intermediate sheet conveying speed of the transfer means may be equal to or lower than the intermediate sheet conveying speed of the sheet holder.

The pressure of the transfer means is so high that it is highest at the central portion and becomes smaller toward both ends.

[0018]

According to the present invention, the intermediate sheet is stretched between the intermediate sheet supply roll for winding the unused portion and the intermediate sheet take-up roll for winding the used portion, The tension of the intermediate sheet at the time of recording and at the time of separation after transfer is provided by providing a configuration for varying the winding force of the intermediate sheet winding roll to a predetermined value. Since it is possible to operate by setting the respective tensions to the optimum tensions, the image on the intermediate sheet is transferred onto the desired image receptor, and the image receptor and the intermediate sheet are transferred.
It is possible to stably separate the sheet from the base material, and it is possible to obtain a good color image in which the expansion and contraction of the image and the misregistration of the color overlap are small.

The intermediate sheet is an intermediate sheet that winds an unused portion.
Intermediate sheet winding roll for winding the supply roll and used part
The winding force of the intermediate sheet winding roll or the intermediate sheet supplying roll is set by the winding force control means, and the winding force is set in the winding force control means. By rotating both of the rolls through the speed reducing means in response to the drive rotation of (1), the winding control means can be downsized and the life can be improved.

The transfer means has a heating body and a pressure roller whose surface is covered with a rubber layer, so that the image receiving surface on which the image is formed is in contact with the pressure roller. By feeding the paper again and fixing the image on the image receiving body by heating and pressurizing the transfer means, the recording apparatus can be downsized and an image with low gloss can be easily obtained.

Further, by setting the intermediate sheet conveying speed of the transfer means to be equal to or lower than the intermediate sheet conveying speed of the sheet holder, the intermediate sheet during the transfer operation can be performed.
Elongation of the sheet is reduced, and wrinkles of the intermediate sheet do not occur,
It is possible to obtain a high-quality color image in which the expansion of the color image transferred to the image receptor is small.

Further, the image on the intermediate sheet can be satisfactorily transferred to a desired image receiving member by pressing the transfer means so that the central portion has the highest pressure and the pressure decreases toward both ends. A high-quality color image can be obtained.

(Not shown) is operated and the intermediate sheet 18 is stretched so as not to sag at all times. Further, since the sheet sandwiching bodies 21 and 22 are constantly pressed against the sheet holding body 3 by the pressing spring 26, the intermediate sheet 18 held by the sheet holding body 3 is not wrinkled. .

Next, the operation of replacing the ink sheet will be described below. In FIG. 1, the second holding plate 53 is pushed in the B direction to release the engagement between the second holding plate 53 and the second positioning shaft 28, and the first unit 1 is rotated clockwise with the opening / closing shaft 31 as a fulcrum. Rotate. Since the engagement between the first holding plate 14 and the first positioning shaft 27 is held, the first unit 1 and the second unit 16 are integrally rotated. Then, the ink sheet 32, the ink sheet supply roll 33, and the ink sheet take-up roll 34 can be replaced from above the recording device.

Next, the printing operation for color image recording will be described below. FIG. 1 is a sectional view of the overall configuration of the first embodiment of the present invention, showing a state during recording.

When the print operation is on standby, the intermediate sheet 18
Is closely attached to the sheet holding body 3 for a predetermined length, and the intermediate sheets 18 at both ends thereof are held by the sheet holding bodies 21 and 22. The ink sheet 32 and the recording head 35 are separated from the intermediate sheet 18.

In the printing operation, first, the intermediate sheet supply roll 19 and the intermediate sheet winding roll 20 are rotated in the respective winding directions, and the rotary drive system is provided with a torque limiter as shown in FIG. The winding force is exerted by the friction drive member 68, and the intermediate sheet 18 is always stretched. When the recording head 35 is pressed, the surface of the ink sheet 32 coated with the color material layer and the surface of the dyeing layer 18b of the intermediate sheet 18 are brought into contact with each other, and the sheet holder 3 is rotated clockwise for recording the first color. To be rotated.

When the recording head 35 is pressed, the color material layer coated surface of the ink sheet 32 and the dyeing layer 18 of the intermediate sheet 18 are pressed.
The surface b is contacted, and the sheet holder 3 is rotated clockwise for recording the first color. At this time, a heat pulse corresponding to the recording signal applied to the recording head 35 is applied to the ink sheet 32.
While receiving from the back side of the sheet, the ink sheet 32 is conveyed as the sheet holder 3 rotates, and the dye layer 18 of the intermediate sheet 18 is conveyed.
The first color is recorded on b. The sheet holder 3 is operated by an operation means capable of designating at least the length of the image to be recorded in the moving direction of the intermediate sheet 18 as an arbitrary recorded image length.
A predetermined amount of rotation is controlled and rotated according to the size of the image receiving body 44 or an image end signal of a designated recording image length. At this time, the intermediate sheet 18 pulled out from the intermediate sheet supply roll 19 is held by the sheet sandwiching body 21 until the sheet is held by the sheet sandwiching body 21. Body 3
It is moved while being held in close contact with the surface of. The intermediate sheet 18 on which the image of the first color is recorded is moved away from the sheet holding member 3 and the sheet holding member 22 by the winding force of the intermediate sheet winding roll 20. .

After the recording of the first color is completed, the rotation of the sheet holder 3 is stopped. Then, the sheet holder 3 is rotated counterclockwise for the recording of the second color. This time,
The intermediate sheet 18 on which the image of the first color has been recorded is brought into close contact with the surface of the sheet holder 3 by the pressing of the sheet sandwiching body 22, and recording starts for recording of the second color. Return to the position. Further, at the time of this reversal, the ink sheet 32 and the recording head 35 are on standby in a state of being separated from the intermediate sheet 18, and press contact with each other in accordance with the recording of the second color, and the second color as well as the first color. The image is recorded. Similarly, when the recording of the third color (the final color) is completed, the sheet holder 3
Is stopped, and the ink sheet 32 and the recording head 3 are stopped.
5 is waited in a state of being separated from the intermediate sheet 18.

Next, in order to transfer the recorded color image on the intermediate sheet 18 to the image receiving member 44 in FIG. 1, the sheet holding member 3 is rotated counterclockwise. Then, the intermediate sheet 18 on which the color image is recorded is fed to the intermediate sheet 18 until the leading edge of the color image recorded on the intermediate sheet 18 reaches a predetermined position where transfer is possible. It is rewound to 19 and the rotation of the sheet holder 3 is stopped.

For transfer, the sheet holder 3 is rotated clockwise and the image receiver 44 in FIG. 1 is fed to the position of the registration roller 48. Further, the heating roller 5 in FIG. 1 which has been separated is pressed at a predetermined timing until the leading edge of the color image recorded on the intermediate sheet 18 reaches the transfer means. 42 against the intermediate sheet
The heater 18 is held and conveyed by the heating roller 5 and the pressure roller 42. At this time, since the intermediate sheet conveying speed of the pressure roller 42 is equal to or less than the intermediate sheet conveying speed of the sheet holder 3, the color image is recorded. The intermediate sheet 18 thus formed has almost no elongation and wrinkles do not occur, and the intermediate sheet 18 is conveyed well.

Further, the pair of registration rollers 47 and 48 are rotated at a timing relative to the leading end position of the color image on the intermediate sheet 18, and the image receiving body 44 is sent out. The image receiving body 44 is conveyed to the transfer means in a state of being in contact with the surface of the dyeing layer 18b of the intermediate sheet 18, and the heating roller 5 from the rear surface of the intermediate sheet 18 heats and melts the dyeing layer 18b and pressurizes it. Thus, the image receiver 44 and the dyeing layer 18b are bonded. Image receptor 4
4 is plain paper, coated paper, or OHP film.

Next, the intermediate sheet 18 and the image receptor 44, which pass between the heating roller 5 and the pressure roller 42 and adhere to each other by melting the dyeing layer 18b, are predetermined by the cooling fan 12. Cooled below the temperature, for example below the glass transition point of the dyeing layer 18b,
The separation roller 11 having a large curvature separates the image-receiving body 44 to which the dyeing layer 18b is adhered and the intermediate sheet base 18a. At this time, the dyeing layer 18b and the ink material recorded on the dyeing layer 18b are transferred onto the image receptor 44 having a strong adhesive force. The smoothness of the surface of the dyeing layer 18b of the transferred color image is almost the same as the surface condition of the separated side of the intermediate sheet base 18a, and the surface of the intermediate sheet base 18a has high smoothness. A glossy color image is obtained. Heating row
The roller 5 is separated from the pressure roller 42 at a predetermined timing after the rear end of the image receiving body 44 has passed through the separation roller 11.

Further, the image receptor 4 to which the dyeing layer 18b is adhered
4 is a pair of discharge rollers 50 which are pressed against each other and rotated.
After passing through 51, the image receiver 44 on which a glossy color image is formed is obtained, and the printing operation is completed.

Next, the operation for obtaining an image with low gloss will be described below. When the image receiving body 44 is plain paper and an image having a low gloss is obtained, the glossy image surface obtained by the printing operation is faced up and the paper feeding cassette 4 is placed.
5 and the heating roller 5 of the transfer means is set to a predetermined temperature. Next, the heating roller 5 is pressed against the pressure roller 42, and the image receiving body 44 on which a glossy image is formed is placed on the sheet feeding cassette 45 and is fed, and the image surface is applied. The heating roller 5 and the pressure roller are brought into contact with the pressure roller 42.
An image with a low glossiness can be obtained by fixing the sheet with the sheet 42 and discharging the sheet. When the temperature of the heating roller 5 is fixed at about 165 ± 5 ° C, which is the same temperature as the transfer,
The dyeing layer 18b follows the surface roughness of the image receiving member 44 and thus the image receiving member 4
It is possible to reduce the glossiness to the extent that the presence of the dyeing layer 18b on No. 4 is not felt. Further, by setting the temperature of the heating roller 5 to be low and fixing the image, an image having an arbitrary glossiness can be obtained.

When the surface roughness of the image receptor 25 is smooth as in the case of coated paper, the set temperature of the heating roller 5 and the rubber layer surface roughness of the pressure roller 42 are relatively high. An image having a desired gloss can be obtained within the gloss range.

When an operation for obtaining an image having a low gloss is performed, the operability is improved, the intermediate sheet 18 is used without waste, and the dyeing layer 18b of the intermediate sheet 18 is not transferred to the back surface of the image receiving body 44. In order to do so, the surface of the used intermediate sheet 18 is wound around the intermediate sheet supply roll 19, and then the image receiving member 44 on which a glossy image is formed is fed and used. The surface of the intermediate sheet 18 and the image receiving member 44 are held by the heating roller 5 and the pressure roller 42 and conveyed. Further, although the operability is lowered, the gloss can be reduced even if the image receiving member 44 on which the glossy image is formed is fed after the intermediate sheet 18 is removed from the recording apparatus.

Next, the operation of the drive system of the intermediate sheet winding roll will be described below with reference to FIGS.

First, as shown in FIG. 4a, a roll drive motor is used.
The pulley 63 and the intermediate gear 64, which are integrally formed with each other via a timing belt 71, are rotated counterclockwise by a motor (not shown). Then, the intermediate gear shaft 59 is generated by the static frictional force that can obtain a rotational torque of about 200 gcm of the frictional drive member 68 in FIG. 3 that is integrally provided on the side surface of the pulley 63.
Is rotated counterclockwise, and the intermediate sheet winding roll 20 is rotated in the winding direction of the intermediate sheet 18 via the intermediate gears 61, 57 and the drive gear 56. The intermediate sheet winding roll 20 is rotated at a speed reduced by about 1/2 of the rotation of the intermediate gear shaft 59. Intermediate sheet winding roll 20
The take-up force can be increased to about 400 gcm, which is the magnitude relative to the reduction ratio with respect to the static friction force generated by the friction drive member 68. The electromagnetic clutch 65 is stopped and the intermediate gears 66 and 67 are idly rotated. The intermediate sheet supply roll 19 shown in FIG. 1 is also rotated in the direction in which the intermediate sheet 18 is wound by the roll drive motor through a similar drive system. Therefore, the intermediate sheet supply roll 19 and the intermediate sheet take-up roll 20 are rotated in the respective winding directions by the roll drive motors to drive the intermediate sheet take-up roll 20. The friction drive member 68 provided in the system and the similar friction drive member (not shown) provided in the drive system of the intermediate sheet supply roll 19 each exert a winding force of about 400 gcm, and the intermediate sheet is supplied. The belt 18 is maintained in a stretched state. Since the sheet holder 3 shown in FIG. 1 is stopped while holding the intermediate sheet 18 in close contact therewith, when the intermediate sheet 18 is stretched to a predetermined tension, the intermediate sheet is wound. In the drive system of the take-up roll 20, slippage occurs between the intermediate gear shaft 59 and the friction drive member 68, and the intermediate gear shaft 59 becomes idle.

Next, the sheet holder 3 in FIG. 1 is rotated clockwise to record the first color. By rotating the sheet holder 3 in the clockwise direction, the intermediate sheet 18
Is withdrawn from the intermediate sheet supply roll 19, and the intermediate sheet is supplied.
It is wound around the supply roll 20. After the recording of the first color is completed, the rotation of the sheet holder 3 is stopped. For recording the second color, the sheet holder 3 is rotated counterclockwise until the leading edge of the first color image recorded on the intermediate sheet 18 reaches a predetermined position. By rotating the sheet holder 3 in the counterclockwise direction, the intermediate sheet 18 is pulled out from the intermediate sheet winding roll 20 and is wound around the intermediate sheet supply roll 19. .

The winding force of the intermediate sheet winding roll 20 when the intermediate sheet 18 is wound is about 400 gcm due to the static friction force of the friction drive member 68. The intermediate sheet 18 is wound in a stretched state. Intermediate sheet 1
When 8 is pulled out, the intermediate gear shaft 59 is rotated counterclockwise with respect to the counterclockwise rotation of the friction drive member 68. Therefore, the winding force of the intermediate sheet winding roll 20 when the intermediate sheet 18 is pulled out is the static friction force of the friction drive member 68, and the dynamic friction force is added to the friction force of the friction drive member 68. The dynamic frictional force is about 1/2 of the static frictional force. As a result, a winding force of about 600 gcm works, and the intermediate sheet 18 is pulled out in a stretched state. The intermediate sheet supply roll 19 also has a similar winding force, and the intermediate sheet 18 is wound and pulled out in a stretched state.

Next, the sheet holder 3 is rotated clockwise in accordance with the recording of the second color, and the image of the second color is recorded by the same operation as that of the first color. Similarly, when the recording of the third color (the final color) is completed, the sheet holder 3
Is stopped. Then, for transfer and separation, the sheet holder 3 is rotated counterclockwise, and the sheet holder 3 is rotated counterclockwise, so that the intermediate sheet 18 is wound by the intermediate sheet. It is pulled out from the take-up roll 20 and wound on the intermediate sheet supply roll 19.

Next, the sheet holder 3 is rotated clockwise to perform the transfer and separation operations. In this transfer and separation operation, the electromagnetic clutch 65 shown in FIG. 3 is provided between the time when the heating roller 5 is pressed by the pressure roller 42 and the time when the tip of the image receiving member 44 reaches the separation roller 11. Is operated, FIG. 4b
The intermediate gear 6 meshing with the intermediate gear 64 as shown in FIG.
6 rotates clockwise, and the intermediate gear shaft 60 rotates clockwise. About 700 gcm by friction drive members 69 and 70 integrally provided on the side surface of the intermediate gear 67 in FIG.
The intermediate gear 6 is driven by the static friction force that can obtain a rotational torque
7 is rotated in the clockwise direction, and the intermediate sheet winding roll 20 is rotated in the direction in which the intermediate sheet 18 is wound via the intermediate gears 62, 61, 57 and the drive gear 56. The intermediate sheet winding roll 20 is about 1/2 of the rotation of the intermediate gear shaft 59.
Since the intermediate sheet winding roll 20 is rotated at a deceleration to some extent, the winding force of the intermediate sheet winding roll 20 is about 1400 g which is the magnitude corresponding to the reduction ratio with respect to the static friction force by the friction drive members 69 and 70.
It has been increased to about cm.

As the intermediate sheet 18, an intermediate sheet which is elastically deformed when stretched to generate an elongation of about 0.1% / 1000 g is used. The minimum winding diameter of the intermediate sheet winding roll 20 and the intermediate sheet supplying roll 19 is about 2 cm, and the intermediate sheet winding roll when the intermediate sheet 18 is pulled out. Since the winding force of the roll 20 and the intermediate sheet supply roll 19 is about 600 gcm, the intermediate sheet 18
Is applied with a maximum tension of about 600 g and is moved in close contact with the sheet holder 3 while being stretched.

Therefore, the elongation of the intermediate sheet 18 rewound on the intermediate sheet supply roll 19 is about 0.0 at maximum.
A method of controlling the counterclockwise rotation speed of the sheet holder 3 having a simple structure in order to reach the recording start position at the leading edge of the image recorded on the intermediate sheet 18, which is about 6%. Even if is used, it is possible to obtain a color image with little color misregistration. Further, even if the transfer operation is performed without stretching the intermediate sheet 18 after the color image is recorded on the intermediate sheet 18 which is stretched by about 0.06% at the maximum, the maximum is about 0.06
It is possible to obtain a color image of a high-quality color image with a shrinkage as small as about%.

In order to separate the image receiving member 44 from the intermediate sheet 18, the tension of the intermediate sheet 18 wound around the intermediate sheet winding roller 20 must be about 800 g or more. It was The maximum winding diameter of the intermediate sheet supply roll 20 is about 3 cm.
Therefore, the winding force of the intermediate sheet winding roll 20 may be about 1200 gcm or more. Therefore, since the winding force of the intermediate sheet winding roll 20 during the separating operation is about 1400 gcm, the intermediate sheet 18 passing through the separating roller 11 moves the image receptor 44 to the intermediate sheet. -Being stretched over a tension larger than that required for separation from the grate 18, it is possible to always obtain a good separation operation.

As described above, according to this embodiment, the light-transmitting dyeing layer 18 is formed on one surface of the continuous sheet-like substrate 18a.

Means and an intermediate sheet 18
Is wound between the intermediate sheet winding roll 20 for winding the unused portion and the intermediate sheet winding roll 20 for winding the used portion, and the intermediate sheet winding roll 20 is wound up. Since the winding force varying means for varying the force to a predetermined value is provided, the winding force of the intermediate sheet winding roll 20 is changed to the intermediate sheet for image recording.
When the sheet 18 is moved, it is small, and when the image receiving member 44 is separated from the intermediate sheet 18 after the transfer, the winding force is set to be large so that the intermediate sheet can be separated during recording and after the transfer. Since each tension can be set to an appropriate tension to operate, the image on the intermediate sheet is transferred onto the desired image receptor, and the separation between the image receptor and the substrate of the intermediate sheet is stabilized. It is possible to provide a recording apparatus that can obtain a good color image with less image displacement and color misregistration.

The intermediate sheet 18 is stretched between the intermediate sheet supply roll 19 for winding the unused portion and the intermediate sheet winding roll 20 for winding the used portion, and the intermediate sheet 18 is wound around the intermediate sheet winding roll 20. Rolling roll 2
0, or the winding force of the intermediate sheet supply roll 19 is set by the winding force control means, and both rolls 19 are driven through the speed reducing means to drive rotation in the winding force control means. Since the winding force of the winding control means can be reduced by rotating the winding control means 20, 20, the winding control means can be downsized and the life can be improved.

An image receiving member 44 having an image 42 is re-fed so that the image surface is in contact with the pressure roller 42, and the image on the image receiving member 44 is fixed by heating and pressure of the transfer unit. As a result, the recording apparatus can be downsized, and an image with low glossiness can be easily obtained.

It is connected to a roll driving motor (not shown) via 74, a pulley 73 and a timing belt 71.

The operation of the drive system of the intermediate sheet winding roll of the color image recording apparatus constructed as described above will be described below with reference to FIGS.

First, as shown in FIG. 5a, the electromagnetic clutch 72 is operated and the pulley 73 is driven by the roll driving motor (not shown) via the timing belt 71.
And the intermediate gear shaft 59 is rotated counterclockwise. The friction drive member 7 integrally provided on the side surface of the intermediate gear 74
The intermediate gear 74 is rotated in the counterclockwise direction by the static frictional force of 5 and 76, which provides a rotational torque of about 700 gcm, and the intermediate sheet take-up roll 20 passes through the intermediate gear 57 and the drive gear 56. -It is rotated in the winding direction of the grate 18. The intermediate sheet winding roll 20 is rotated at a speed reduced by about 1/2 of the rotation of the intermediate gear shaft 59. The winding force of the intermediate sheet winding roll 20 is the friction driving member 7
It can be increased to about 1400 gcm, which is the size corresponding to the reduction ratio with respect to the static friction force of Nos. 5 and 76.
Since a winding load torque of about 100 gcm is applied to the winding roll 20, a winding force of about 1300 gcm is obtained.

The intermediate sheet supply roll 19 shown in FIG.
Is an electromagnetic clutch 72 driven by the roll driving motor.
About 40 by the static friction force of a friction drive member (not shown) via a drive system such as that provided with the friction drive member 75.
The intermediate sheet 18 is rotated in a winding direction by a winding force of about 0 gcm.

Therefore, the intermediate sheet supply roll 19 and the intermediate sheet winding roll 20 are rotated in the winding direction by the roll drive motor, respectively, and the intermediate sheet winding roll is rotated. The friction drive members 75 and 76 provided in the drive system of 20 and the friction drive member (not shown) provided in the drive system of the intermediate sheet supply roll 19 act as predetermined winding forces, respectively. The belt 18 is maintained in a stretched state. Since the sheet holder 3 shown in FIG. 1 is stopped while holding the intermediate sheet 18 in close contact therewith, when the intermediate sheet 18 is stretched to a predetermined tension, the intermediate sheet is wound. In the drive system of the take-up roll 20, the intermediate gear shaft 59 and the friction drive members 75, 7
Slip occurs between 6 and the intermediate gear shaft 59 becomes idle.

Next, the sheet holder 3 in FIG. 1 is rotated clockwise to record the first color. By rotating the sheet holder 3 in the clockwise direction, the intermediate sheet 18
Is withdrawn from the intermediate sheet supply roll 19, and the intermediate sheet is supplied.
It is wound around the supply roll 20. After the recording of the first color is completed, the rotation of the sheet holder 3 is stopped and the operation of the electromagnetic clutch 72 is stopped. For recording the second color, the sheet holder 3 is rotated counterclockwise until the leading edge of the first color image recorded on the intermediate sheet 18 reaches a predetermined position. By rotating the sheet holder 3 in the counterclockwise direction, the intermediate sheet 18 is pulled out from the intermediate sheet winding roll 20 and is wound around the intermediate sheet supply roll 19. .

The winding force of the intermediate sheet winding roll 20 when the intermediate sheet 18 is wound is the friction drive member 75,
In addition to the static frictional force of 76, there is a rotational load torque of about 100 gcm, so a winding force of about 1300 gcm works.
The intermediate sheet 18 is wound in a stretched state. Intermediate sea
When the seat 18 is pulled out from the intermediate sheet winding roll 20, the electromagnetic clutch 72 is stopped and the break member 77 abutting against the roll support shaft 54 is used to wind up the intermediate sheet. Since the rolling load torque of about 100 gcm is applied to the roll 20, the intermediate sheet 18 is stretched with a small tension and pulled out from the intermediate sheet winding roll 20.

Further, the winding force of the intermediate sheet supply roll 19 when the intermediate sheet 18 is wound around the intermediate sheet supply roll 19 shown in FIG. A winding force of about 400 gcm is exerted by a static friction force (not shown), and the intermediate sheet 18 is wound in a stretched state. Intermediate sheet 18
The winding force of the intermediate sheet supply roll 19 when the sheet is pulled out is about 600 gcm due to the static friction force and the dynamic friction force of the friction drive member (not shown), and the intermediate sheet 1
8 is stretched and pulled out from the intermediate sheet supply roll 19.

Next, the electromagnetic clutch 72 is operated in accordance with the recording of the second color and the sheet holder 3 is rotated in the clockwise direction, and the image of the second color is imaged by the same operation as the first color. Is recorded. Similarly, the third color (the final color)
When the recording is completed, the electromagnetic clutch 72 is stopped and the sheet holder 3 is stopped. Then, for transfer and separation, the sheet holder 3 is rotated counterclockwise, and the sheet holder 3 is rotated counterclockwise, so that the intermediate sheet 18 is wound by the intermediate sheet. It is pulled out from the take-up roll 20 and wound on the intermediate sheet supply roll 19.

Next, the electromagnetic clutch 72 is operated to perform the transfer and separation operations, and the sheet holder 3 is rotated clockwise. After the rear end of the image receiver 44 to which the color image on the intermediate sheet 18 is transferred passes through the separation roller 11 of FIG. 1, the intermediate sheet winding roll 20 is driven at a predetermined timing. Roll drive motor and electromagnetic clutch 72

In the transfer and separation operations, the winding force of the intermediate sheet winding roll 20 is about 1300 gcm, and the winding force of the intermediate sheet supply roll 19 is about 600 gcm. The intermediate sheet 18 is wound and pulled out by the same winding force as that at the time of recording.

As the intermediate sheet 18, an intermediate sheet 18 which is elastically deformed when stretched to cause elongation of about 0.1% / 1000 g is used. The minimum winding diameter of the intermediate sheet winding roll 20 and the intermediate sheet supplying roll 19 is about 2 cm, and the intermediate sheet winding roll when the intermediate sheet 18 is pulled out. Since the winding force of the roll 20 is about 100 gcm or less and the winding force of the intermediate sheet supply roll 19 is about 600 gcm or less, the intermediate sheet 18 has a maximum of about 600 g.
A tension of a certain degree is applied, and the sheet holder 3 is moved in close contact with the sheet holder 3 while being stretched.

Therefore, the elongation of the intermediate sheet 18 rewound on the intermediate sheet supply roll 19 is about 0.0 at maximum.

Even if is used, it is possible to obtain a color image with little color misregistration. Further, even if the transfer operation is performed without stretching the intermediate sheet 18 after the color image is recorded in a state of being stretched to the maximum of about 0.06%, the maximum is about 0.06%. It is a shrinkage, and a color image of a high-quality color image can be obtained.

In order to separate the image receiving member 44 from the intermediate sheet 18, the tension of the intermediate sheet 18 wound around the intermediate sheet winding roller 20 must be about 800 g or more. It was The maximum winding diameter of the intermediate sheet winding roll 20 is about 3 cm.
Therefore, the winding force of the intermediate sheet winding roll 20 may be about 1200 gcm or more. Therefore, since the winding force of the intermediate sheet winding roll 20 during the separating operation is about 1300 gcm, the intermediate sheet 18 passing through the separating roller 11 moves the image receptor 44 to the intermediate sheet. -Being stretched over a tension larger than that required for separation from the grate 18, it is possible to always obtain a good separation operation.

As described above, according to the second embodiment, the winding force of the intermediate sheet winding roll 20 by the winding force control means is adjusted by the intermediate sheet 18 to the intermediate sheet winding. When the intermediate sheet 18 is wound around the roll 20, the image receiving body 44 after transfer can be separated from the intermediate sheet 18 by a large winding force, and when the intermediate sheet 18 is pulled out from the intermediate sheet winding roll 20. Is set to a small winding force, the expansion of the intermediate sheet 18 rewound to the intermediate sheet supply roll 19 can be reduced, so that the counterclockwise rotation speed of the sheet holder 3 is reduced. By controlling, the leading edge of the image recorded on the intermediate sheet can reach a predetermined position, and a recording apparatus having a simple structure can be obtained. In addition, since the tension of the intermediate sheet can be set to an appropriate tension at the time of recording and at the time of separation after the transfer, the image on the intermediate sheet can be transferred onto a desired image receiving member. It is possible to provide a recording device that can stably separate an image receptor and a base material of an intermediate sheet, and that can obtain a good color image with less image expansion and contraction and color misregistration positional deviation. is there.

A pressing force W is applied to both ends of the heating roller 5, and the pressure between the heating roller 5 and the pressure roller 42 is equal to or higher than the required pressure c as shown by a line a in FIG. A case will be described below in which the transfer operation is performed in this state, and as the image receiving body 44, the coated paper coated with the resin on both sides of the paper is used.

Image receptor 4 heated by heating roller 5
Since it is difficult to evaporate the moisture in the image recording medium 4 from the back surface of the image receiving member 44, the moisture is moved to the rear end direction of the image receiving member 44 and to the central portion direction where the pressing force is small, and the moved water partially increases. Occurs. For this reason, a portion where the water content is increased due to movement during the transfer is moved to the image receiving body 44 while heating the dyeing layer 18b of the intermediate sheet 18 by the heat of the heating roller 5, The temperature is lower than the melting temperature of the dyeing layer 18b, and an image in which a portion which is not fused and transferred to the image receptor 44 is generated is obtained.

Next, a pressing force W is applied to both ends of the heating roller 5, and the heating roller 5 and the pressure roller 5 are pressed as indicated by a line b in FIG.
A case will be described in which the transfer operation is performed in a state where the pressure between the rollers 42 is the required pressure c or more and the central portion is large, and as the image receiving body 44, the coated paper coated with the resin on both sides of the paper is used.

Image receptor 4 heated by heating roller 5
Although it is difficult to evaporate the water in 4 from the back surface of the image receiving body 44, since the water is moved in the rear end direction of the image receiving body 44 and in the both end directions where the pressing force is small, there is a place where the water partially increases. Does not occur. As a result, the heating roll during the transfer is
The heat of the layer 5 is transferred to the image receiving body 44 substantially uniformly while heating the dyeing layer 18b of the intermediate sheet 18, and there is no place where the temperature is below the melting temperature of the dyeing layer 18b, so that the dyeing layer 18b is dyed. Layer 18
A good image in which b is fused on the entire surface can be obtained.

In the above description, the heating roller 5 and the pressure roller 5 are used.
The center portion of the heating roller 5 is formed to have a convex shape so that the pressing force in the axial direction between the rollers 42 is the highest in the central portion and gradually decreases toward both ends. As shown in FIG. 12, the central portion of the pressure roller 42a may be formed in a convex shape, or the central portion of the core metal of the pressure roller 42a may be formed in a convex shape, or a combination of these shapes may be used. The same effect can be obtained.

As described above, according to the fourth embodiment, the intermediate sheet 18 having the light-transmitting dyeing layer 18b on one surface of the continuous sheet-shaped substrate 18a, and the recording position. A sheet holder 3 which is detachable from the sheet and holds the other surface of the intermediate sheet 18, and an ink material for the dyeing layer 18b with the intermediate sheet 18 held by the sheet holder 3 And a dyeing layer 18b of the intermediate sheet 18 with the surface of the intermediate sheet 18 on which the ink material is recorded and the image receiving member 44 being in contact with each other. It has a transfer means for transferring the above-recorded ink material to the image receiving body 44 by a medium of heat and pressure, and a separating means for separating the image receiving body 44 from the intermediate sheet 18 after the transfer, and the pressure of the transfer means is Apply pressure so that the central part is the highest and becomes smaller toward both ends. As a result, the transfer means has the heating body 5 and the pressure roller 42 whose surface is covered with a rubber layer, and the pressure of the transfer means is heated so that the central portion has the highest pressure and the pressure decreases toward both ends. At least one of the body 5 and the transfer roller 42 is formed in a convex shape in the central portion with respect to both ends, and the transfer means is a pressure roller in which the heating body 5 and the surface are covered with a rubber layer. 42, the pressure of the transfer means is highest in the central portion and becomes smaller toward both ends, and the core metal of the transfer roller 42 is formed in a convex shape in the central portion with respect to the both ends. In addition to plain paper, it is possible to satisfactorily transfer the image on the intermediate sheet 18 onto a desired image receiving member 44 such as coated paper coated with resin on both sides of the paper, and a high-quality color image. Is what you can get.

The structures and materials of the members used in FIGS. 1 to 12 are shown below in detail. The adhesive surface of the sheet holder is molded by molding a 3 mm thick silicone rubber (a combination of a release silicone resin and an adhesive silicone resin) on the outer peripheral surface of a core metal having a diameter of 14 mm. The one manufactured in a state close to the mirror surface was used. In addition, as the adhesive material, fluorosilicone rubber, fluorine rubber, urethane rubber, chlorosulfonated polyethylene and the like can be used.

The degree of tackiness depends also on the smoothness of the rubber surface, and the tackiness increases as the surface becomes closer to a mirror surface. As an index of tackiness, it is represented by the peeling force when the intermediate sheet is peeled off (JI
SZ0237 180 degree peeling method), if the value is 0.1 g / inch or more, the effect of preventing thermal contraction of the intermediate sheet can be expected, and if the transportability of the intermediate sheet or the image receptor is taken into consideration, it is 1 g. / Inch or more 3g / inc
h or less was appropriate. To confirm this effect,
It is measured by the amount of shrinkage of the intermediate sheet after recording by applying energy of 5 J / cm ^{2 to} the round head. When the peeling force of the surface of the sheet holder was 0.1 g / inch, the heat shrinkage amount was about 0.2 mm per 200 mm width, and about 1 g / inch or more was about 0.15 mm. In addition, the meandering and slipping of the intermediate sheet and the image receiving body were hardly generated. By the way, when using a non-sticky rubber material, about 0.3mm
No heat shrinkage was observed, and meandering occurred unless the pressing force in the axial direction of the sheet holding body was finely adjusted. For the intermediate sheet used at this time, a polyethylene terephthalate film (thickness: 23 μm, manufactured by Lumira Toray Co., Ltd.) was used as an intermediate sheet substrate, and a polyvinyl butyral resin (BL-S) was used on the surface thereof. Average degree of polymerization: about 350 Sekisui Chemical Co., Ltd. 4 parts by weight, siloxane-containing acrylic silicone resin solution (F-6A active ingredient 54 wt%, Sanyo Chemical Industry Co., Ltd.) 0.24 parts by weight, di-n -Butyl tin durarate 0.001 part by weight, toluene 18 parts by weight, 2-
A dyeing layer was formed by applying a paint consisting of 18 parts by weight of butanone.

Various polymer films can be used as the intermediate sheet substrate. Examples of various polymer films include polyolefin-based, polyamide-based, polyester-based, polyimide-based, polyether-based, cellulose-based, polyoxadiazol-based, polystyrene-based, and fluorine-based films. In particular, polyethylene terephthalate, polyethylene naphthalate, aramid, triacetyl cellulose, polyparabanic acid, polysulfone, polypropylene, cellophane, moisture-proof cellophane, or polyethylene film is useful.

The dyeing layer is formed using at least a polymer. Various polymers can be used as the polymer. For example, there are acrylic resins, styrene resins, urethane resins, polyester resins, polyvinyl acetal resins, vinyl acetate resins, amide resins, cellulose resins, chlorinated resins, and the like. In particular, acrylonitrile-styrene copolymer resin, polystyrene, styrene-acrylic copolymer resin, saturated polyester, polyether urethane, chlorinated rubber, chlorinated polypropylene, vinyl chloride resin, chlorinated vinyl chloride resin, vinyl chloride-vinyl acetate copolymer resin (In addition, vinyl alcohol, maleic acid, and other components may be copolymerized), vinyl chloride-acrylic acid ester copolymer resin (including multi-component copolymer resin using a plurality of acrylic acid esters), acetic acid When at least one kind selected from vinyl resin, polycarbonate or cellulose resin is used, the sublimation dye transfer recording has high recording sensitivity and is good.

The glass transition point of the polymer is 40 ° C. to 150 ° C.
And the average degree of polymerization of the polymer is in the range of 150 to 3000, or the flow softening point is 300 ° C. or less. For the purpose of transferring the dyeing layer to the image receiving body or fixing the dyeing layer resin into the fibers of the paper when the image receiving body is porous such as paper, the average degree of polymerization is 2000 or less and the molecular weight is high. Molecules or flow softening point is 250
A polymer having a temperature of ℃ or less is particularly desirable. Since the dyeing layer on which an image is formed is transferred onto the image receptor, the dyeing layer is preferably a polymer having high transparency. Polyvinyl acetal is particularly preferable as the polymer of the dyeing layer. As the polyvinyl acetal, various aldehydes such as formaldehyde, acetaldehyde, propion acetal, polyvinyl alcohol, polyvinyl butyral and the like are particularly useful for polyvinyl alcohol.

The ink sheet was prepared in the following manner using a sublimation type thermal transfer recording sheet. A polyethylene terephthalate film having a slip heat-resistant layer on the lower surface and an anchor coat layer on the upper surface is coated with the following three color paints on the anchor coat layer, and cyan, magenta and yellow are coated. An ink sheet having each color material layer was prepared. Table 1 shows the composition of each paint.

[Table 1]

Using the above ink sheet, the thermal head was pressed against the intermediate sheet holder (about 3 kg), and recording was performed under the recording conditions shown in (Table 2).

[0113]

[Table 2]

Further, as the ink sheet, a heat melting type recording sheet can also be used. It has a viscosity of 1 when melted.
An ink sheet having cyan, magenta, and yellow color material layers of 0,000 centipoise was used. The recording conditions when these are used are shown in (Table 3).

[0115]

[Table 3]

Further, it is possible to record a sublimation type thermal recording color material and a heat melting type recording material in a mixed manner on the dyeing layer of the intermediate sheet. For example, a photographic image can be formed on the dyeing layer. It is also excellent and expensive according to the present invention that an extremely high quality recorded image can be obtained by utilizing the features of both recording methods by thermally recording with a sublimation dye and recording the character portion with a heat-melting color material.

As described above, the present invention is particularly effective in a thermal recording method involving shrinkage of an intermediate sheet at the time of recording. For example, a recording method for forming a color image by superimposing colors such as ink jet recording. Also, regarding the above, there is an excellent effect in that a high-quality image can be obtained regardless of the accuracy of repeated position accuracy and the type of image receptor.

Details of the transfer means will be described below. The heating roller 5 heats the inside of a cylindrical metal roller with a halogen lamp, and is controlled to a predetermined roller surface temperature by a thermistor provided in contact with the outer peripheral surface. In practice, it was used in the range of 165 ° C ± 5 ° C. Pressure roller 4
For No. 2, a silicon rubber roller having a rubber thickness of 3 mm and a diameter of 20 mm and a hardness of 70 degrees was used. Transfer pressure is 10kg
Used at / 220 mm.

In the above description, the heating roller used in the fixing means has been described, but instead of this, a heating body having a fixed elongated heat generating portion, for example, a ceramic substrate having a width of 3 mm. It is possible to use, as a heating source, a surface of the heating element surface coated with the resistance coating, which is covered with a Teflon-treated polyimide film. The same effect can be obtained even if the film surface temperature is controlled by a thermistor built in the heating element by applying an alternating current to this heating element and used in a temperature range of 165 ° C. ± 5 ° C., for example. In particular, by using a heating body having a fixed elongated heat generating portion, about 3
The transfer temperature can be raised to a predetermined transfer temperature, for example, 165 ° C. in less than a second, no warm-up is required, and power consumption is reduced.
The print time can be shortened.
