PURPOSE:To promoter color mixing by performing the recording well even on a low smoothness medium to be recorded by a method wherein a vibration means for vibrating a pressure means to the medium to be recorded is provided, and a roller component of the pressure means is made to have anisotropy in peripheral rigidity and axial rigidity. CONSTITUTION:An image is formed by selectively applying heat energy and specific wavelength optical energy to a medium 1 to be transfer-recorded with a recording part 3. The medium 1 to be transfer-recorded is overlapped on recording paper 8 being a medium to be recorded and is jointed by heat and pressure to transfer the image to the recording paper 8 with a transfer part 8. Further, it is wound around a winding roll 6. Besides, pressure, heat, and shearing force are applied to the recording paper 8 by a pressure means 13 and a vibration means 14 vibrating the recording paper. Color mixing of a transferred image is promoted and besides, the paper is fixed to be discharged to a discharge tray 11. A color mixing roller 13a in the pressure means 13 has an hollow part 13a4 passed through axially and a rib 13a7. Consequently peripheral rigidity becomes larger than axial rigidity. 300cs silicone oil 13a5 is enclosed in the hollow part 13a4 and further, a halogen heater 13c is established at a central part of an aluminum roller 13a1.

Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a recording device for recording an image on a recording medium, and more particularly to a recording device that can be used in a printer, a copying machine, a facsimile, or the like.

<Prior Art> In recent years, with the rapid development of the information industry, various information processing systems have been developed, and recording devices suitable for each information processing system have also been developed.

One of the above recording devices is a thermal transfer recording device. In this method, recording is performed on a recording paper using an ink ribbon made by coating a ribbon-shaped support with a hot-melt ink made by dispersing a colorant in a hot-melt binder.

That is, the ink ribbons are stacked so that their heat-melting ink layers are in contact with the recording paper, and the ink ribbon and the recording paper are conveyed between the thermal head and the platen, and the ink ribbon is transferred from the support side of the ink ribbon to the thermal head. By applying pulse-shaped heat according to the image signal and pressing the two together and transferring the molten ink to the recording paper, an ink image corresponding to the heat application is recorded on the recording paper. .

The above recording apparatus has been widely used in recent years because it is small and lightweight, makes no noise, and can record on plain paper.

Problems to be Solved by the Invention However, conventional thermal transfer recording devices are not without problems. The reason is that in conventional thermal transfer recording devices, the transfer recording performance, that is, the image quality, is greatly affected by the surface smoothness of the recording paper.
Although good image recording is performed on recording paper with high smoothness, there is a possibility that the quality of image recording will deteriorate when recording paper with low smoothness is used.

Furthermore, in the conventional thermal transfer recording apparatus, when attempting to obtain a multicolor image, it is necessary to repeat transfer to overlap the colors. For this purpose, it is necessary to provide multiple thermal heads or to make complicated movements such as stopping and reversing the recording paper, which not only makes color misalignment unavoidable, but also makes the entire device large and complicated. There are challenges.

<Means for solving the problem> Therefore, the present applicant uses a photothermal sensitive material, and when thermal energy and light energy are applied, the reaction of the material proceeds rapidly and the transfer characteristics change irreversibly. proposed a technique for forming an image based on the difference in characteristics according to the signal and transferring it to a recording medium.

No. 95 (published on July 30, 1988), etc. 1. According to this technology, it is possible to record high-quality images even on recording media with low surface smoothness, and when applied to multicolor recording, it is possible to make complex movements on the recording medium. It is possible to obtain multi-colored images without any problems.

The purpose of the present invention is to further develop the above technology, and to improve the coverage of images formed on recording media, and to improve the mixing of each color in multicolor recording to produce high quality images. The purpose is to provide a recording device that can be obtained.

A typical means according to the present invention for this purpose is to apply a first energy and a second energy different from the first energy to a transfer recording layer, the transfer characteristics of which are changed, on a support. a conveyance means for conveying a transfer recording medium, which is provided along a conveyance path of the transfer recording medium conveyed by the conveyance means, for applying the first energy to the transfer recording medium; a recording section having a first energy applying means and a second energy applying means for applying the second energy; and a transfer member made of an inelastic body that contacts the support side of the transfer recording medium; a transfer section for transferring the image formed on the transfer recording medium in the recording section to the recording medium; and a transfer section for contacting the recording medium that has passed through the transfer section and applying at least pressure to the recording medium. , the roller member of the pressing means has a rigidity in the circumferential direction and a rigidity in the axial direction. It is characterized by having anisotropy in its stiffness.

Effect> According to the above means, when the transfer recording medium and the recording medium are set in the apparatus and recording is performed, multiple types of energy are applied to the transfer recording medium in the recording section to form an image. The image is transferred to the recording medium in the transfer section. Furthermore, when the recording medium to which the image has been transferred is ejected, at least pressure is applied to fix the image on the recording medium. At this time, due to the slight movement of the pressurizing means,
Each color in a multicolor record is mixed, resulting in a high-quality image with enhanced color mixing. Furthermore, since the roller member of the pressure means has anisotropy in rigidity in the circumferential direction and the axial direction, even if there are minute irregularities on the image surface, the roller member surface will be in close contact with the image surface, and pressure and vibration will not be applied to the image surface. The shearing force is applied reliably by means to ensure color mixing of the image. Practical Example> Next, an example of the present invention to which the above means is applied will be described in detail. [First Embodiment] FIG. 1(8) is a sectional explanatory view of a recording apparatus according to the first embodiment, and FIG. 1(B) is a perspective explanatory view. First, we will explain the general configuration of this device. In the figure, reference numeral 1 denotes a long sheet-shaped transfer recording medium, which is wound into a roll and is removably incorporated into the apparatus main body M as a supply roll 2. That is, this supply roll 2 is removably loaded onto a rotatable shaft 2a provided in the main body M of the apparatus. The leading edge of this transfer recording medium 1 is connected to the supply roll 2. Guide roller 1

Thereafter, the transfer recording medium 1 is fed out in the direction of arrow a by rotating the transfer roller 4a while applying torque to the take-up roll 6 in the direction of arrow C using a known driving means. In synchronization with the feeding of the transfer recording medium, the recording unit 3 selectively applies thermal energy and light energy of a predetermined wavelength to the transfer recording medium 1 to form an image, and the transfer unit 4 transfers the recording medium to the recording medium. The image is superimposed on the paper 8 and transferred to the recording paper 8 by applying heat and pressure. Further, the transfer recording medium 1 after the image transfer is wound onto a winding roll 6. On the other hand, pressure, heat, and shearing force are applied to the recording paper 8 by a pressure means 13 and a vibration means 14 that vibrates the pressure means 13, which promotes color mixing of the transferred image on the recording paper 8 and fixes it on the discharge tray. It is structured so that it wanders into 1). Incidentally, when winding up the transfer recording medium 1, a certain back tension is applied to the supply roll 2 by, for example, a known means such as a hysteresis brake (not shown).
Due to this tension and the guide rollers 12a and 12b, the transfer recording medium 1 is kept under a constant pressure against the recording head 3a and -. It is configured so that it is conveyed while being pressed against it at a certain angle. Next, the configuration of each of the above parts will be explained in detail. A transfer recording layer 1b having a property capable of forming an image when both thermal energy and light energy are applied is deposited on a sheet-shaped support la. To explain one example, in this example, the transfer recording layer 1
The components shown in Table 1 below were used as core 1b+ of core 1b, and the components shown in Table 2 were used as core lbz. A microcapsule-shaped image forming element is formed by using the components shown in Table 3 and the method shown below. (The following is a blank space) First, the transfer recording medium 1 is prepared by mixing 100 g of water and 26 g of isobutylene-maleic anhydride copolymer (ISOBAN-10, manufactured by Kureha Chemical Co., Ltd.) as shown in FIG. Add 10 g of sodium and stir at 80°C for 6 hours. After further cooling to room temperature, 700 g of pectin 3.1 aqueous solution was mixed therein and stirred for 20 minutes. The pH of 200 g of the above isobane-pectin mixture was adjusted to 4.0 with a 20% sulfuric acid solution, 0.2 g of Quadrol (manufactured by BASF) was added, and this was mixed with a homomixer for 30 minutes.
While stirring at 000 rpw+, a solution prepared by dissolving 20 g of the components shown in Tables 1 to 3 above in 30 g of chloroform was added over 10 to 15 seconds, and emulsification was continued for 10 minutes.

Further, the emulsion was transferred to a 500 Wl beaker and continued to be stirred with a stirring blade for 1 to 2 hours to distill off the solvent. Then 8.3 g of urea solution (50% by weight), 0.4 g of resorcin dissolved in 5 g of water, lO. 7g formalin (
37%) and 0.6 g of ammonium sulfate dissolved in 10 yd of water are added at 2 minute intervals.

After raising the temperature to 60"C and continuing stirring for 3 hours, lower the temperature and adjust the pH to 12.0 with 20% caustic soda solution. After passing through iLi, the capsule liquid was washed twice with 1000-degree water. and drying to obtain a micro-force particle-like image forming element.The image forming element comprises core 1b+,
lbw. It is a microcapsule in which lbz is coated with a shell lbn, and the particle size is 7 to 15 nm, with an average particle size of about 10 mm. The image forming element thus formed is adhered onto a support la using an adhesive 1bs to obtain a transfer recording medium 1.

To explain the above-mentioned attachment method in more detail, for example, the polyester adhesive Polyester T.
p-022 (solid content 50%) lee to toluene 3cc
Adhesive 1bs dissolved at a ratio of 1.0 to 1.0 cm is applied onto a support la made of a polyethylene terephthalate film with a thickness of 6 nm. After that, remove the solvent by drying and reduce the thickness to about 1 [
Make it. This adhesive 1bs has a glass transition point = l5°C
Therefore, a slight tack remains even at room temperature, and the image forming body formed as described above can be easily transferred to the support 1. It is possible to attach it to a.

Next, a microcapsule-shaped image forming element using the materials shown in Tables 1 to 3 obtained as above as a core material was prepared in 1.
: Mix at a ratio of 1:1 and sprinkle this on to adhere. after that. When the excess image-forming element is brushed off, the image-forming element is disposed on the adhesion layer in approximately one layer and at a rate of 90%.

Thereafter, a pressure of about 1 kgr/cd and thermal energy of about 80° C. are applied to firmly fix the image forming element on the support la, thereby forming a transfer recording medium l.

The photoinitiator in the image-forming element shown in Table 1 has the absorption characteristics shown in FIG. 3 in the band of graph A (peak wavelength 29
The photoinitiator in the image forming element shown in Table 2 has a wavelength of 389 nm (peak wavelength of 389 nm) and starts a reaction by absorbing light of 389 nm). ), the reaction starts, and the color becomes cyan during image formation.The photoinitiator in the image forming element shown in Table 3 has a wavelength of ) absorbs light and starts a reaction, resulting in a yellow color when forming an image. Next, the recording section 3 will be explained. In this embodiment, the recording section 3 includes a heating means for applying thermal energy, which is first energy, to the transfer recording medium 1, and a heating means, which applies light energy, which is second energy, to the transfer recording medium 1. 1, and a light irradiation means for imparting light to The heating means consists of 1728 line-type heating elements 3b arranged in a row on the surface of the recording head 3a for A-4 size with a width of 0.2 fl and 8 dots/double, which generate heat according to the image signal. As described above, the support la side of the transfer recording medium 1 is configured to be pressed against the heating element 3b with a predetermined pressure by the back tension during conveyance. The image signal is generated from a control unit of a facsimile, an image scanner, an electronic blackboard, or the like, depending on the purpose.

On the other hand, a light irradiation means is provided on the transfer recording layer lb side facing the recording head 3a. This light irradiation means has the characteristics shown in FIG. 4 as a spectral transmittance, and has a thickness of 2 f.
Glass with an inner diameter of 40mm (manufactured by SCIIOTT in West Germany, product name DIIRAN 50) A rotary body 3C made of a cylindrical cylinder is connected to three pairs of rollers 3d, 3e. 3f, and is configured to rotate at a constant speed by driving and rotating the roller 3d with a motor. Furthermore, three types of phosphors A, B, and C are coated on the inner surface of the rotating body 3C in stripes of 120 degrees each (divided into three equal parts) in the circumferential direction. In this example, Ca(POa)m+T1 (thallium-activated calcium phosphate) is used as the main component of the phosphor A, and (Sr.Mg)xPxOr:Eu (europium-activated strontium magnesium) is used as the main component of the phosphor B. pyrophosphate), and Ba, MgAI+hOgy as the main components of phosphor C:
Eu (eurobium activated barium magnesium aluminate) is used. A light source 3g is disposed inside the rotating body 3C, and the phosphors A, B, and C are configured to emit light when the light source 3g is turned on. In this embodiment, a low-pressure mercury lamp is used as the light source 3g, and when this light source 3g is turned on, the phosphor A emits light as shown in graph A in FIG. 5 (peak wavelength 335nw).
, phosphor B has a peak wavelength of 390 na in graph B in Figure 5.
), phosphor C is graph C in Figure 5 (peak wavelength 450
It emits light with a spectral distribution of nm). The light emitted by the phosphors A, B, and C passes through a slit 31 with a width of 0.5 mm formed in the light shielding plate 3h and irradiates the transfer recording layer 1b. Therefore, when the rotating body 3C is rotated and light is irradiated from the light source 3g, the phosphors A, B, and C are excited and emit light in order, and the light with different spectral distribution passes through the slit t-3i and reaches the transfer recording layer 1b. They are irradiated in order. Here, a control configuration for controlling the rotational speed and phase of the rotating body 3C will be explained.

As shown in FIG. 1(B), the rotating body 3c has a large number of light shielding parts 3j formed in stripes at regular intervals on the circumference near the end, and one light shielding part 3J' of the light shielding parts 3J' is formed on the circumference near the end. It is formed wider than the light shielding part 3. Moreover, the light shielding part 3j
A light emitting member 3k such as an LED is disposed inside the rotating body 3C so as to sandwich the rotating body 3C, and a light receiving member 3g such as a photodiode is disposed outside. From the above configuration, when the rotating body 3C is rotating at a constant speed, the signal obtained from the light receiving member 3l is as shown in FIG. 6(A). Note that the level r low 1 shown in FIG. , the light is not received by the light receiving member 31. Therefore, since the frequency of the rising edge of the signal appears as the rotational speed of the rotating body 3C, it is possible to control the rotational speed of the rotating body 3C by detecting and controlling this. In addition, for phase control, the integral waveform shown in Figure 6 (^) is obtained and the result is as shown in Figure 6 (B).Since one of the light shielding parts 3j (3j') is wide, the integral of that part is The wave height value increases. Therefore, based on the timing when the peak value becomes high, the magenta line synchronization signal, cyan line synchronization signal, yellow line synchronization signal, video clock, which will be described later,
A strobe signal, an enable signal, etc. are created, and during the first r high j period of the enable signal, the phosphor A of the rotating body 3C is
is opposed to the transcription record [1b] through the slit 31, phosphor B is opposed during the second r-high 1 period of the enable signal, and phosphor C is opposed during the third r-high period of the enable signal. All you have to do is to control the gate so that it does, and repeat this sequentially for each "high" enable signal. Therefore, in this embodiment, PLL (Phase Lo) is used to rotate the rotating body 3c at a constant speed and phase.

It corresponds to 31. Note that the light source motor 31a is a motor that drives a roller 3d that supports a rotating body 3c,
F C3l b is the output of the light receiving member 3l. In this embodiment, the output of the FC3l b and the phase comparison output of the motor clock are obtained from a phase comparator 30a, and in order to further stabilize the system, the output of the FC3l b is integrated by a monostable multi-bicycle plate 30b. The difference between the output and the output of the phase comparator is applied to the VCO 31 through a low-pass filter 30c and a power amplifier 30d.

Also, in FIG. 7, the lock detector 30e is the phase comparator 30a.
This is to detect whether or not the system is in a synchronized state from the signals from. Also, the output of FG3lb is integrator 30r
The rotational phase reference signal is obtained by integrating the waveform (corresponding to FIG. 6 ([1))] using the waveform shaping H30g.

Next, this transfer section 4 will be explained. The transfer section 4 is disposed downstream of the recording section 3 in the transport direction of the transfer recording medium I, is driven to rotate in the direction of arrow b as shown in FIG. 1, and is pressed against the support Ia side of the transfer recording medium I. The transfer roller 4a is a transfer member, and a pressure roller 4b is pressed against the transfer roller 4a via the transfer recording medium 1 and the recording paper 8 and rotates as a result of the transfer roller 4a.

The transfer roller 4a is composed of an aluminum roller whose surface is coated with silicone rubber having a thickness of 1 m and a hardness of 70 degrees, and the surface is maintained at a temperature of 90 to 100 degrees Celsius by a built-in 800W halogen heater 4C. has been done.

The pressure roller 4b is made of an aluminum roller coated with silicone rubber having a hardness of 70 degrees, and the pressing force of the transfer roller 4a is increased to 6 to 7 krf/1 by a pressure means (not shown) such as a spring. am.

Further, as shown in FIG. 1(^), recording paper 8, which is a recording medium, is loaded in the cassette 7, and the recording paper 8 is fed one by one by a feeding roller 9 and a pair of registration rollers 10a and tab. The leading edge of the fed recording paper 8 is detected by a registration sensor 28 consisting of an LED 28a and a phototransistor 28b, and the feeding timing is controlled, thereby separating the image area of the transfer recording medium 1 and the recording paper 8. The structure is such that the transfer parts are fed to the transfer unit 4 in synchronization so that they overlap. Therefore, when the transfer part 4 is polished, the image forming part of the transfer recording medium l overlaps the recording ring 8, and in this state, pressure and heat are applied to the transfer recording medium l when it passes between the rollers 4a and 4b. The image is transferred to Record 8. The recording paper 8 onto which the image has been transferred in the transfer section 4 is pressed by 1,000 steps l3.
However, at this time, the pressurizing means 1 is recorded in the record 8.
Pressure and heat are applied at 3.

The pressure means 13 is disposed downstream of the transfer section 4 in the conveyance direction of the recording paper 8, and is composed of a color mixing roller 13a and a pressure roller 13b that presses against the roller 13a.

As shown in FIG. 8(^), the color mixing roller 13a is a hollow aluminum roller 13a+ whose circumferential surface is coated with silicone rubber 13a* having a thickness of 31 cm, and fluororubber latex 13a is coated on the surface with a thickness of approximately 31 cm. Coated with 30 lna. Further, a plurality of hollow portions 13a penetrating in the axial direction are formed in the silicone rubber l3ax portion, and the hollow portions 13a

As a result, the surface of the color mixing roller 13a reaches approximately 150 to 160'C.
It is structured so that it is maintained. In FIG. 8(A), 13ab is silicone rubber 13a. to prevent the silicone oil 13an sealed in the cavity 13a from leaking out. It is a cap that can be attached to both ends of the . By configuring the color mixing roller 13a as described above,
The axial rigidity and circumferential rigidity of the roller 13a have anisotropy. That is, the color mixing roller 13a of this embodiment has a hollow portion 13a4 passing through in the axial direction, and this hollow portion 138
Reply 13a between 4? , the circumferential rigidity of the roller 13a is greater than the axial rigidity of the roller 13a. The pressure roller 13b is made of silicone rubber with a thickness of about 3N, and is supported by the color mixing roller 13a and a spring (not shown) to provide a pressure of about 0.1 to Q. It is configured to make pressure contact with a pressing force of 3 kgf/cm. Further, the color mixing roller 13a is configured to be rotated in the direction of arrow d by a color mixing motor, which will be described later. Note that the color mixing roller 13a is rotationally controlled by a drive transmission means (not shown) connected to the color mixing motor so that the rotational peripheral speed of the color mixing roller 13a is the same as the speed at which the recording paper 8 is conveyed by the transfer roller 4a. Further, a vibration unit l4 serving as a vibration means is attached to the color mixing roller 13a. To explain this specifically, as shown in FIG. 8(B), the color mixing roller 13a is rotatably attached via a bearing unit 13a, and the voice coil 14a and the magnetic circuit are connected to the bearing unit 138. Vibration unit l consisting of 14b
4 is installed. and the vibration unit l4
When driven, the color mixing roller 13a moves at a frequency of about 100Hz in the axial direction (direction of arrow e) perpendicular to the conveying direction of the recording paper 8.
, which generates minute vibrations with an amplitude of about 0.3fi. still,
In FIG. 8, 14c is a color mixing roller gear connected to the drive transmission means of the color mixing roller 13a. Next, we will explain the recording method when recording using the recording device configured as described above. Note that this embodiment shows an example in which heat is applied according to an image signal and light is applied uniformly. The transfer recording medium 1 is sequentially fed out from the supply roll 2 by driving the motor, and an image is formed by applying light and heat to the transfer recording layer 1b of the transfer recording medium 1 in the recording section 3 in accordance with the west signal. ．． The transfer recording layer 1b has a property that when light and heat of a predetermined wavelength are applied, the softening point temperature increases, that is, the transfer characteristics change irreversibly, and the transfer recording layer 1b is no longer transferred to the recording paper 8. ．． Therefore, as shown in the timing chart of FIG. 9, when recording magenta color, among the heating element rows, the heating element 3b corresponding to the complementary color of magenta of the image signal, that is, the green image signal.

The transfer recording layer 1b is irradiated with light energy having the spectral distribution shown in graph A in FIG. Next, in cyan color recording, 50-S after the start of energization to the heating element 3b in the magenta color recording, this time, the complementary color of cyan, that is, the part corresponding to the red image signal in the heating element array is applied for 20 ms. At the same time, the light source 3g is turned on for 20 ms. At this time, the phosphor B of the rotating body 3c is facing the transfer recording layer 1b located in the slit 31, and the light energy of the spectral distribution shown in graph B in FIG. 5 is uniformly applied to the transfer recording layer 1b. Ru. Next, when recording the yellow color, 50 ms after the start of energization to the heating element 3b during the cyan recording, the 351IIS is energized to the complementary color of yellow, that is, the part corresponding to the blue image signal in the array of heating elements. At the same time, the light source 3g is turned on for 35ms. At this time Surin}3
The transfer recording layer tb located at 1 has a phosphor C of the rotating body 3C.

As described above, a transfer image is formed on the transfer recording layer 1b by controlling the heat generation of the heating element 3b, the rotation of the rotating body 3c, and the lighting of the light source 3g according to the image signals of complementary colors of magenta, cyan, and yellow. 150ms/Lins for this image formation
The transfer recording medium is conveyed synchronously with the repetition period of . Here, the control system according to this embodiment for performing the above recording operation will be specifically explained with reference to FIGS. 10 to 16. In addition, Fig. 10 is a block diagram of the control system, Fig. 1) and Fig. 12 are timing charts of recording operation, and Fig. 13
14 is a sequence table for sending each signal, FIG. 15 is a flowchart of the recording operation, and FIG. 16 is a circuit diagram of the temperature control system of the transfer roller 4a. As shown in FIG. 10, this control system includes a CPU 20a, a microprocessor, etc.
A ROM 20b that stores control programs and various data for the CPU 20a, a control unit 20 that is used as a work area for the CPU 20a, and a RAM 20C that temporarily stores various data, an interface 2l, a recording density, etc. An operation panel 22 with manual switches such as the number of sheets, an image forming timing generator 23, a driver 25a for driving the feed motor 24, a driver 25a for driving the feed motor 25, and a driver 25a for driving the color mixing motor 26. It consists of a driver 26a, a driver 27 for driving the vibration unit 16, a registration sensor 28 for detecting the tip of the register 8, a light source lighting device 29 for lighting the light source 3g, and a PLL motor driver 30.

The control unit 20 receives various information (for example, recording density, number of recording sheets, etc.) from the operation panel 22 via the interface 2l.
recording size, etc.), a signal from the registration sensor 28, a magenta line synchronization signal generated by the image forming timing generator 23, and a lock detection signal from the PLL motor driver 30. Further, the control section 20 outputs, via the interface 21, a motor ON signal for the feeding motor 24 and the transport motor 25, a page signal, a color mixing motor ON signal (also serves as a vibration unit ON signal), and a light source motor ON signal. The image forming timing generator 23 divides the clock of the internal crystal oscillator and generates various signals (magenta line synchronization signal, cyan line synchronization signal, yellow line synchronization signal, page synchronization signal, video clock, enable signal, strobe signal, (light source ON signal, motor reference clock, etc.). The magenta line sync signal, cyan line sync signal, and yellow line sync signal are as shown in Figure 13.
The cycle is 150 m, the duty ratio is 1/3, and the phase is 1.
The signal is shifted by 20 degrees. Furthermore, the magenta line synchronization signal is created based on the rotation/phase reference signal from the PLL motor driver 30. Then, a page signal sent from the control unit 20 via the interface 21 is latched at the rising edge of the magenta line synchronization signal to generate a page synchronization signal.

The video clock is a signal that generates a 36κHz clock from the rising edge of the magenta, cyan, and yellow line synchronization signals, and stops after generating 1728 clocks (approximately 48 m). Further, an external image signal generator (for example, facsimile, image scanner, electronic Kurosaka, etc.) 32 receives a page synchronization signal from the image forming timing generator 23, magenta, cyan,
When the yellow line synchronization signal and video clock are received, the page synchronization signal becomes "high 1", and when the magenta line synchronization signal is r high 1, the magenta image signal is transmitted, and when the cyan line synchronization signal is r high J, the page synchronization signal is "high 1". Similarly, when the yellow line synchronization signal is "high j", 1728 yellow image signals are sent out in synchronization with the video clock. Furthermore, a strobe signal is generated which becomes "high 1" during the r high j period of the magenta, cyan, or yellow line synchronization signal, during which the video clock is at rest.

The enable signal starts from the first cyan line synchronization signal when the page synchronization signal becomes "high 1," and then sequentially changes from the rising edge of the cyan, yellow, and magenta line synchronization signals to "high 1" of IoIls, 20ms, and 35ss.
Repeat this, and the page synchronization signal becomes "35*s within the period of high 1 of the first magenta line synchronization signal that became low 1.
It ends with the occurrence of r-high J. This enable signal corresponds to the energization signal to the heating element 3b corresponding to the image signal shown in FIG.

Further, the image forming timing generator 23 generates an optical moN signal. The light source ON signal starts from the rising edge of the cyan line synchronization signal, and at each rising edge of each enable signal, l
Repeat r high 1 in the order of 抛S, 2抛s, 35+ms.

Further, the image forming timing generator 23 generates a motor reference clock for creating a motor clock to be given to the PLL motor driver 30. This clock is 6 kHz
The motor clock is a continuous clock of Z, and is given to the PLL motor driver 30 via a switch controlled by a light source motor ON signal sent from the control unit 20 via the interface 21.

The recording head 3a takes in an image signal from an external image signal generator 32 into a shift register inside the hend using a video clock from an image forming timing generator 23. This taken-in image signal is latched in the rough register in the head by the strobe signal from the image forming timing generator 23, and then the heating element is latched according to the image signal in the rough register by the enable signal from the image forming timing generator 23. 3b is energized, and at the same time as the energization, the next image signal is taken into the shift register by the video clock. Further, the lighting device 29 of the light source 3g receives an AND signal of the ON signal of the light source 3g from the image forming timing generator 23 and the light source motor ON signal from the interface 21,
When the signal is r high 1, the light source 3g is turned on.

As shown in FIG. 7, the PLL motor driver 30 drives the light source motor 31a so that the manually operated motor cloth and the output from the light receiving member 3l (FIG. 6(A)) are phase synchronized. Furthermore, this PLL motor driver 30 is connected to the control unit 2 via the interface 2I.
A lock detection signal is sent to the image forming timing generator 23 to notify that phase synchronization is applied to the rotational body 3c, and a rotational phase reference signal is sent to the image forming timing generator 23 for synchronizing the rotating body 3c with the line synchronization signal.

In this embodiment, the light shielding portion 3j. on the rotating body 3c. The number of 3j' is 900, and PLL motor driver-3
If the light source motor 31a is in the same phase state due to 0, the rotating body 3c rotates at a speed of 150 ms per revolution because the motor clock is 6 kflz as described above.

An image is formed on the transfer recording medium 1 by the control described above.

Next, the conveyance control of the transfer recording medium 1 and the recording sleeve 8 for transferring the image formed on the transfer recording medium 1 to the recording sleeve 8 will be explained.

The feed motor driver 24a is connected to the interface 2
When the feed motor ON signal from the control unit 20 is r-high 1 through `1, the feed motor 24 is driven, and the feed roller 9 and the registration roller pair 10a, 10b are rotated to keep the recording paper 8 constant. Convey at speed.

Further, the transport motor driver 25a also controls the transport motor O from the control section 20 via the interface 21.
When the N signal is "high j", the conveyance motor 25 is driven to rotate the transfer roller 4a, and in cooperation with the pressure roller 4b which rotates as a result of this, the transfer recording medium l and the recording medium 8 are
is transported at a constant speed. Color mixing motor driver 26a
Similarly, when the color mixing motor ON signal from the control unit 20 is
When high 1, the color mixing motor 26 is driven and the color mixing roller 1
Rotate 3a. At this time, as described above, the drive transmission system is set so that the rotational circumferential speed of the color mixing roller 13a and the conveyance speed of the recording paper 8 by the transfer roller 4a are the same speed.

Further, when the color mixing motor ON signal from the control unit 20 is "high J," the vibration unisoto driver 27 turns the vibration unit H6 ONL and vibrates the color mixing roller 13a in the direction of arrow e in FIG.

Here, the timing of each signal sent by the control section 20 via the interface 2l is as shown in FIG.

Note that the times T and ~T in FIG. 12 correspond to the times when the transfer recording medium 1 or the recording medium 8 is conveyed as shown below, assuming that the distances between the members are L and ~L4 as shown in FIG. 13. This is the time required for

LI: Conveyance distance of the transfer recording medium l from the recording head 3a to the pressure contact portion between the transfer roller 4a and the pressure roller 4b.

L. ; Conveyance distance of the transfer recording medium 1 from the pressure contact portion to the peeling roller 5. L: Transport distance of the recording sleeve 8 from the registration sensor 28 to the pressure contact portion, L4: Transport distance of the recording sleeve 8 from the peeling roller 5 to the color mixing roller 13a.

The time required to convey the transfer recording medium 1 by 7 m). T4: Move the transfer recording medium 1 to a distance L. +t,, I! time required to send.

T,: Time required to convey the recording paper 8 a distance ML4. That is, when the operator presses the start button on the operation panel 22, the feeding motor 24 is driven, feeds the recording paper 8, and stops driving when the leading edge of the recording paper 8 touches the registration sensor 28. At this point, the rotating body 3C rotated by the light source motor 31a is phase-synchronized by the control described above. Next, the conveyance motor 25 is driven to move the transfer recording medium 1 along the arrow a in FIG.
At the same time, the page signal becomes "high 1" during time T3, and a transfer image forming process is performed in the recording section 3.

The conveyance motor 25 stops after the image forming time T has elapsed and after a further time T4 has elapsed.

The feed motor 24 is driven for a time T2 after a time T has elapsed since the start of conveyance of the transfer recording medium 1, conveying the recording shaft 8 at the same speed as the transfer recording medium 1, and then stopping. As a result, the leading edge of the recording band 8 matches the leading edge of the transfer image formed on the transfer recording medium 1 in the transfer section 4, and is conveyed by the drive of the conveyance motor 25 while being in close contact with the transfer recording medium 1.

Now, to explain the operation of the control unit 20 that sends out each signal as shown in FIG. ．． That is, since the magenta line synchronization signal has a cycle of 150 as described above, the control section 20 can manage time by counting the signal. The control unit 20 has a sequence table as shown in FIG.
Then, while counting magenta line synchronization signals, sequentially refer to the sequence table
The N signal, the conveyance motor ON signal, the page signal, and the color mixing motor ON signal are sent, and the drive of each member is controlled by each signal. In this embodiment, the sequence table has a 4-bit structure as shown in FIG. 14, and consists of a total of 3496 words from the 0th to the 3496th word, where bit 0 is the feed motor ON signal and bit 1 is the feed motor ON signal. The transport motor ON signal, bit 2 corresponds to the page signal, and bit 3 corresponds to the color mixing motor ON signal (including the vibration unit ON signal). In addition, the numbers in the power saw at the top of FIG. ).

Next, a series of operations of the control unit 20 having the above-mentioned functions will be explained using the flow chart of FIG. 15. First, in step S1, it is detected whether or not the start button on the operation panel has been pressed. If so, proceed to step S2, send the feeding motor ON signal, and then proceed to step S2.
Send the light source motor ON signal at step 3. Next step S
Step S4 waits for the registration sensor signal to become rhigh 1, and when the signal becomes "high", the process moves to step S5 and waits for the lock detection signal from the PLL motor driver 27 to become "high". . That is, it waits for phase synchronization of the rotating body 3C. When the lock detection signal becomes r-high 1, the process moves to step S6 and 0 is substituted into R indicating the rask number of the sequence table. Next, in step S7, the magenta line synchronization signal is
, and then waits for the magenta synchronization signal to become "high" in step S8. This detects the rising edge of the magenta line synchronization signal.
When the edge is detected, the process moves to step S9 and refers to the R-th bit of the sequence table.
Bit 1) Turn on the feed motor for bit 2 and bit 3 respectively.
It is sent as a signal, a transport motor ON signal, a page signal, and a color mixing motor ON signal.

Next, the process moves to step SIO, where 1 is added to the value of R, and it is detected whether the value of R is greater than 3496 in step S11. If the value of R is smaller than or equal to 3496, the process returns to step S7 to continue recording; if it is larger, the process proceeds to step 312 to stop the light source motor 31a and end the recording.

The image formed as described above is transferred to the recording medium 8 by applying heat and pressure in the transfer section 4. Here, the transfer section 4
The temperature control configuration is as shown in Figure 16. The thermistor Ts in FIG. 16 is arranged so as to be in contact with the surface of the transfer roller 4a, and its resistance value changes depending on the surface temperature of the transfer roller 4a.已。 and the comparator C
0 and is compared with the reference voltage Eo. The comparison output is relay driver R. Power supply E, by relay RL via
Controls the energization of the halogen heater 4C. Here, we will discuss the driving principle of the temperature control configuration. The thermistor Tw has a property that the resistance value decreases as the temperature rises, so if the surface temperature of the transfer roller 4a rises, the thermistor T. The resistance value decreases, and the voltage E2 decreases. Conversely, if the surface temperature of the transfer roller 4a decreases, the thermistor T.
The resistance value of increases and the voltage E2 also increases. Therefore, the reference voltage E
By setting the temperature to a value of 300° C., when the surface temperature of the transfer roller 4a is lower than 95° C., the comparison output becomes rhighj, the halogen heater 4C is energized, and the surface temperature of the transfer roller 4a increases. Conversely, if the temperature is higher than 95°C, the halogen heater 4C is not energized and the surface temperature drops. Due to the above control, the surface temperature of the transfer roller 4a is 90 to 100.
It is held at °C. This control system is constantly operating when the power switch of the device is on, and is controlled so that the surface temperature of the transfer roller 4a reaches 90 to 100 degrees Celsius before the start button on the operation panel is pressed. .

The structure for maintaining the surface of the color mixing roller 13a at 150 to 160 degrees Celsius is also the same as described above. As described above, an image is formed on the transfer recording medium 1, and the image is transferred to the recording medium 8 in the transfer section 4 as a color image of magenta, cyan, and yellow. After the image has been transferred to the recording paper 8 as described above, the transfer recording medium 1 is separated from the recording paper 8 by the peeling roller 5, and the transfer recording medium 1 is wound onto the take-up roll 6. On the other hand, the surface of the recording paper 8 that has passed the peeling roller 5, on which the image has been transferred, comes into pressure contact with the color mixing roller 13a, and pressure and heat are applied thereto. At this time, as shown in FIG. 17, the surface of the recording paper 8 has minute irregularities due to the transfer of the image forming elements 15a and 15b, but the color mixing roller 13a
The silicone rubber 13a2 is easily elastically deformed, and the silicone rubber 13az portion has a cavity 1 that penetrates in the axial direction.
3a, the color mixing roller 13a is easily deformed in the opposite direction. Therefore, color mixing roller 1
The surface of 3a is in close contact with the image surface of recording paper 8. On the other hand, the color mixing roller 13a has a hollow portion l3a4 in the axial direction.
Because there is a rib 13a between them, it is less likely to deform than in the circumferential direction. Therefore, when the color mixing roller 13a is slightly vibrated by the vibration means 14 in a direction perpendicular to the conveying direction of the recording paper 8,
Shearing force is effectively applied by the vibration of the color mixing roller 13a that is in close contact with the image surface. Furthermore, since the silicone oil 13as is sealed in the cavity 13a4, the heat of the heater 13c is effectively transmitted to the image surface.

Therefore, the capsules of the image forming element are reliably destroyed by the shearing force, the colors between the adjacent capsules are mixed, and the colors are fixed on the recording paper 8 by pressure and gentle application. Here, the color mixing state will be specifically explained with reference to the drawings. For example, the blue-purple image transferred to the recording medium 8 by the transfer unit 4 is cyan as shown in FIGS. 18(A) and 18(B). It is formed by transferring the color image forming element 15a and the magenta color image forming element 15b.

When this image passes through the color mixing roller 13a, the image shown in FIG.
) and (B), the application of the pressure, heat, and shearing force progresses the destruction of the image forming elements 15a, 15b, improving the coverage, and improving the coverage of the image forming elements 15a, 1.
Color mixing at the 5b boundary progresses, making the blue-purple image clearer and improving the image quality. The recording paper 8 on which a high-quality image with enhanced color mixing has been recorded as described above is discharged onto the discharge tray 1).

(2) Recording section In the first embodiment described above, in the recording section 3, light of a predetermined wavelength corresponding to a desired color is uniformly irradiated from the transfer recording layer 1b side of the transfer recording medium 1, and the support is Although the configuration is such that heat is applied from the 1a side in accordance with the image signal, another embodiment may be configured in which heat is applied uniformly and a predetermined light is irradiated in accordance with the image signal. Furthermore, if the support 1a is made of a translucent material, the support 1a can be made of a transparent material.
A configuration may be adopted in which light is irradiated from the a side and heat is applied from the transfer recording layer 1b side.

Furthermore, in the first embodiment described above, light irradiation and heat application were performed with the support 1a in between, but image formation could also be achieved by separately performing both light irradiation and heat application from one side of the support 1a. It is possible. Further, as the heating means, in addition to the method using the recording head 3a described above, a method of selectively heating using a YAG laser and a polygon mirror, etc. may be used. Furthermore, the light irradiation means need not be limited to the method using the rotating body 3c described above. For example, a plurality of individual fluorescent lamps capable of emitting light corresponding to each wavelength may be provided, and each fluorescent lamp may be individually turned on in response to an image signal. Furthermore, in addition to the fluorescent lamp, for example, a method using an LED array, a method using a xenon lamp and a filter matching the light absorption characteristics of the material, etc. may be used.

In the above-mentioned embodiment, light energy and thermal energy were applied to the transfer recording layer 1b at the same time. However, even if the optical energy and thermal energy are applied separately, the result is that both energies are applied separately. Any configuration that is given is acceptable.

In the first embodiment described above, an example of color recording in magenta, cyan, and yellow was shown, but the characteristics of the transfer recording medium 1,
By selecting the heat and light energy application characteristics in the recording section 3, it is of course possible to perform one-color recording or two-color recording.

<3> Transfer section In the above-described embodiment, heat and pressure are applied to the transfer section 4, but it is also possible to apply only pressure to the transfer section 4. Further, in the first embodiment, a roller-shaped transfer member such as the transfer roller 4a is used as the transfer member, but there is no need to limit it to this. For example, a belt-shaped member may be used, and any structure that can obtain the desired pressure may be used. Good. This also applies to the pressure roller 4b.

(4) Pressure means Since the color mixing roller 13a is in pressure contact with the image surface of the recording paper 8, in order to prevent offset of the transferred image, as shown in FIG. 20 (^). A cleaning mechanism may be provided as shown in (B). In the configuration shown in FIG. 20(A), a felt par 16a made of aromatic polyamide resin fibers is coated with 5,000 to 1
A roller impregnated with fO00cs silicone oil is pressed against the color mixing roller 13a. When assembled as described above, the surface of the color mixing roller 13a that has come into contact with the image on the recording paper 8 is cleaned by the felt parser 16a, and offset of the image forming element can be prevented. Further, the configuration shown in FIG. 20(B) is one in which a cleaning heel 16b made of aromatic polyamide resin made into a web shape and impregnated with silicone oil in the same manner as described above is pressed against the color mixing roller 13 by a pressure roller 16c. Therefore, the same effect as in the case of FIG. 20(A) can be obtained.

In this case, it is preferable to make minute vibrations at a vibration frequency of about 15 to 50 kHz. In addition, in the first embodiment described above, the vibration frequency was set to 100
Hz and amplitude of 0.3, but it goes without saying that the vibration frequency and amplitude of the color mixing roller 13a are not limited to the above values. <Effects of the Invention> As described above, the present invention sequentially performs the formation of an image on a transfer recording medium and the transfer of this image to a recording medium, so that an image can be formed even on a recording medium with a relatively low surface smoothness. Records can be recorded well. Furthermore, when the present invention is applied to multicolor recording, a multicolor image can be obtained without making any complicated movements on the recording medium. Furthermore, by applying at least pressure and shear force to the recording medium on which an image has been formed, the coverage range of the image can be improved, and when applied to multicolor recording, the color mixing of each color can be enhanced. Furthermore, since the roller member of the pressure means has anisotropy in rigidity in the circumferential direction and the axial direction, even if there are minute irregularities on the image surface, the roller member surface will be in close contact with the image surface, and pressure and vibration will not be applied to the image surface. It is possible to reliably apply shearing force by means of means and ensure color mixing of images.
