Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a recording device for recording an image on a recording medium, and more specifically to a recording device that can be used in a printer, a copying machine, a facsimile, etc. ．． BACKGROUND 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. This involves recording on recording paper using an ink ribbon made by coating a ribbon-shaped support with a heat-melt ink made by dispersing a colorant in a heat-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-mentioned recording device 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, when trying to obtain a multicolor image with a conventional thermal transfer recording device, it is necessary to repeat the transfer to overlap the colors. For this purpose, it is necessary to install 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 other issues.

Means to Solve 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 technology for forming an image based on the difference in characteristics according to the image signal and transferring it to a recording medium.

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, thereby producing high quality images. The aim is to provide a recording device that can be used to record images. A typical means according to the present invention for this purpose is a transfer record having a transfer recording layer whose transfer characteristics change by applying a first energy and a second energy different from the first energy. a conveyance means for conveying a medium; and a first energy application for applying the first energy to the transfer recording medium, provided along a conveyance path of the transfer recording medium conveyed by the conveyance means. a recording section having a second energy applying means for applying the second energy; a transfer section for transferring the image formed in the recording section to a recording medium; a discharging means for discharging the recording medium to which the image has been transferred; and a discharging means for discharging the recording medium to be discharged;
The recording medium is characterized by being provided with an adsorption means for adsorbing the recording medium to the ejection means, and a pressure means for applying at least pressure to the ejected recording medium. 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.

Further, 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, if the pressure means is made to vibrate minutely, each color in the multicolor recording will be mixed, the color mixing of the image will be promoted, and a high quality image will be obtained. Furthermore, when the recording medium is ejected, it is adsorbed by the suction means to the ejecting means, so even if the pressure means slightly vibrates, the recording medium does not follow and vibrate, thereby preventing the color mixture. <Embodiment> Next, an embodiment of the present invention to which the above means is applied will be described in detail.

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 conveyed while being pressed against the recording head 3a at a constant pressure and at a constant angle. Next, the configuration of each of the above parts will be explained in detail. First, as shown in FIG. 2, the transfer recording medium 1 has a transfer recording layer 1 having the property of forming an image when both thermal energy and light energy are applied on a sheet-like support la.
It is formed by attaching b. To explain one example, in this example, the components shown in Table 1 below were used as the core 1b+ of the transfer recording layer 1b, and the core tb. Using the components shown in Table 2 and the components shown in Table 3 as the core Ibz, a microcapsule-shaped image forming element was formed by the method shown below.

First, 100 g of water and 26 g of isobutylene-maleic anhydride copolymer (ISOBAN-10, manufactured by Kureha Chemical Co., Ltd.) are mixed, sodium hydroxide Log is added, and the mixture is stirred 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. 200 g of the above isovan-vectin mixture was adjusted to p8 4.0 with a 20% sulfuric acid solution, 0.2 g of Quadrol (BASF!) was added, and this was mixed with a homomixer for 30 minutes.
While stirring at 000 rpm, a solution prepared by dissolving 20 g of the components shown in Tables 1 to 3 in 30 g of chloroform was added over 10 to 15 seconds, and emulsification was continued for 10 minutes.

Further, the emulsion was heated to 500+#I. Transfer to a beaker, continue stirring with a stirring blade for 1 to 2 hours, and distill off the solvent. Next, 8.3 g of urea solution (50% by weight), 0.4 g of resorcinol dissolved in 5 g of water, 10.7 g of formalin (37%) and 0.6 g of ammonium sulfate dissolved in 10- of water were added. Add at 2 minute intervals.

+1 bz, L bz are microcapsules coated with seal 1l}4, and are formed to have a particle size of 7 to 15 μm and an average particle size of about 101.

The image forming element thus formed is adhered onto a support la using an adhesive 1bs to obtain a transfer recording medium l. To explain the above-mentioned attachment method in more detail, for example, the polyester adhesive Polyester LP manufactured by Nippon Gosei Kagaku Kogyo
-022 An adhesive 1bs prepared by dissolving 3 cc of toluene in lee (solid content 50%) is applied onto a support la made of a polyethylene terephthalate film with a thickness of 6 mm. Thereafter, the solvent is removed by drying to make the thickness about 1-. Since this adhesive 1bs has a glass transition point of -15°C, a slight tack remains even at room temperature, and the image forming agent formed as described above can be easily attached to the support 1a. ．． Next, a microcapsule-shaped image forming element using the materials shown in Tables 1 to 3 as core materials obtained as above was prepared.
Mix in the ratio of 1) and sprinkle this on to adhere. Thereafter, when excess image forming elements are brushed off, the image forming elements are arranged on the adhesion layer in approximately one layer and at a rate of 90%. Thereafter, the image forming element is firmly fixed on the support la by applying a pressure of about i hriai and thermal energy of about 80° C. to form the transfer recording medium 1. The photoinitiator in the image forming element shown in Table 1 absorbs light in the band shown in graph 8 (peak wavelength 298 ns) and starts a reaction in the light absorption characteristics shown in FIG. The color becomes magenta, and the photoinitiator in the image forming element shown in Table 2 is

In this embodiment, the recording unit 3 includes a heating means for applying thermal energy, which is first energy, to the transfer recording medium 1, and a heating means, which also applies light energy, which is second energy, to the transfer recording medium 1. It consists of a light irradiation means for

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 donts/I, which generate heat according to the image signal. As described above, the support la side of the transfer recording medium l is configured to be pressed against the heat generating element 3b with a predetermined pressure by the pack tensile force during conveyance. Note that the west signal is emitted from a control unit of, for example, a facsimile, an image scanner, or an electronic blackboard, 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.

A rotating body 3C made of a cylinder made by Company T, product name IIURAN 50) is rotatably supported by three pairs of rollers 3d, 3e, and 3f, and is rotated at a constant speed by driving and rotating the rollers 3d by a motor. It is structured as follows. Moreover, three types of phosphors A, B. C is applied to stripes of 120 degrees (3 equal parts) in the circumferential direction. In this example, Ca(POn)t:Tl (thallium-activated calcium phosphate) is used as the main component of the phosphor 8, and (Sr+Mg)zPaot:Eu (europium-activated strontium magnesium) is used as the main component of the phosphor B. pyrophosphate), and Ba, MgA1+60zt 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 335 nm).

emits light with a spectral distribution of m). 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 sequence, and each light with a different spectral distribution passes through the slit l-3+ and reaches the transfer recording layer 1b. irradiated in sequence.

Here, a control configuration for controlling the rotational speed and phase of the rotating body 3C will be explained. The rotating body 3c is the first
As shown in Figure (B), a large number of light shielding parts 3j are formed in a stripe shape at regular intervals on the circumference near the end, and one of the light shielding parts 3j' is wider than the other light shielding parts 3j. is formed. Further, a light emitting member 3k such as an LED is disposed inside the rotating body 3c so as to sandwich the light shielding portion 3j, and a light receiving member 3l such as a photodiode is disposed on the outside.

From the above configuration, the signal obtained from the light receiving member 31 is as shown in FIG. 6(A) when the rotating body 3c is rotating at a constant speed. Note that the level "low 1" shown in FIG. The light receiving member 3j is shielded from light! It is in a state where no light is received. 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 frequency. In addition, for phase control, when the integral waveform of FIG. 6(A) is obtained, it becomes as shown in FIG. 6(B), and one of the light shielding parts 3j (
3j') is wide, the integrated wave height value of that part becomes high. Therefore, the magenta line synchronization signal, cyan line synchronization signal, yellow line synchronization signal, video clock, strobe signal, enable signal, etc., which will be described later, are created based on the timing when the peak value becomes high, and the first r high of the enable signal is generated. During the period j, the phosphor A of the rotating body 3C faces the transfer recording layer 1b through the slit 31, and during the period ``2nd r high'' of the enable signal, the phosphor B faces, and during the 3rd period of the enable signal. During the r high 1 period, the phosphor C

Also, in FIG. 7, the lock detector 31e is the phase comparator 31a.
This is to detect whether or not the system is in a synchronized state from the signals from. Also, the output of FG32b is the integrator 31f
The waveform (corresponding to FIG. 6(B)) is shaped by a waveform shaper 31g to obtain a rotational phase reference signal. Next, this transfer section 4 will be explained. The transfer section 4 is disposed downstream of the recording section 3 in the conveyance direction of the transfer recording medium 1, and is in pressure contact with a transfer roller 4a that rotates in the direction of arrow b as shown in FIG. and a pressure roller 4b that rotates as a result of rotation.

The transfer roller 4a is composed of an aluminum roller coated with silicone rubber with a hardness of 70 degrees and a surface strength of 70 degrees, and the surface is maintained at 90 to 100 degrees Celsius by a built-in 800 W halogen heater 4C. It is configured as follows.

The pressure roller 4b is an aluminum roller coated with silicone rubber having a hardness of 70 degrees to a thickness of 1)A, and the pressing force with the transfer roller 4a is 6 to 7 kgf by means of pressure means (not shown) such as a spring. /cm. Further, as shown in FIG. 1(A), a recording medium 8 as a recording medium is loaded in the cassette 7, and this recording medium 8 is fed one by one by a feeding roller 9 and a pair of registration rollers 10a and 10b. The image area of the transfer recording medium 1 and the recording target 8 are separated by detecting the leading edge of the recording target 8 and controlling the feeding timing by a resist sensor 26 consisting of an LED 26a and a phototransistor 26b. The configuration is such that the images are fed to the transfer unit 4 in synchronization so that they overlap.

Therefore, in the transfer section 4, the image forming portion of the transfer recording medium 1 overlaps the recording gage 8, and in this state, pressure and heat are applied to the transfer recording medium 1 when it passes between the rollers 4a and 4b. The image is transferred to Record 8. The recording unit 8 onto which the image has been transferred by the transfer unit 4 is transferred to the ejecting means 13
Next, this ejecting means 13 will be explained.

The pressure roller 15b is grounded to the main body M of the apparatus.The color mixing roller 15a is an aluminum roller whose surface is coated with Teflon (registered trademark) resin to a thickness of about 25 mm. In this embodiment, a 300W halogen heater 15c, which serves as heating means for the recording paper 8, is provided inside the color mixing roller 15a, and the surface of the color mixing roller 15a is maintained at 150 to 160°C by this heater 15c. It consists of

Therefore, while the recording paper 8 to which the image has been transferred by the transfer section 4 is discharged by the discharge means 13, constant pressure and heat are applied by the color mixing roller 15a. This application of pressure and heat effectively destroys the image forming element transferred to the recording paper 8, and the colors are mixed and fixed on the recording paper 8. The color mixing roller 15a is connected to a discharge motor that drives the drive roller 13a described above via a drive transmission system (not shown), and is configured to be driven and rotated in the direction of arrow e in FIG. The circumferential rotational speed of the discharge bell H3c is controlled to be the same as the circumferential rotational speed of the discharge bell H3c. As described above, the image on the recording sleeve 8 is mixed and fixed by the pressure means 15, but in this embodiment, the color mixing roller 15a is provided with a vibrating means to further promote the color mixing. As shown in FIG. 8, this vibration means is a color mixing roller 15a.
A vibration unit 16 consisting of a voice coil 16a and a magnetic circuit 16b is attached via a bearing unit 15al. When the vibration unit 16 vibrates, the color mixing roller 15a moves at a frequency of approximately 100F+2 in the axial direction (direction of arrow f) perpendicular to the conveyance direction of the recording paper 8.
It is configured to produce minute vibrations with an amplitude of approximately 0.3fi. In FIG. 8, 16c is a gear connected to the drive transmission system of the color mixing motor, which will be described later. Next, a recording method when recording is performed using the recording apparatus configured as described above will be explained.

Note that this embodiment shows an example in which heat is applied according to an image signal and light is applied uniformly. The motor is driven to sequentially feed out the transfer recording medium l from the supply roll 2, and an image is formed by applying light and heat to the transfer recording layer tb of the transfer recording medium l in the recording section 3 according to the image 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 layer 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.

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 1lb located in the slit 31, and the optical energy of the spectral distribution shown in graph B in FIG. 5 is uniformly applied to the transfer recording layer 1b. It will be done. Next, for yellow color recording, 501 seconds after the start of energization to the heating element 3b in the cyan color recording, 35 ms of current is applied to the complementary color of yellow, that is, the part corresponding to the blue image signal in the heating element array. At the same time, the light source 3g is turned on for 35...S. At this time, the phosphor C 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 the graph C of FIG. 5 is uniformly applied to the transfer record rgib. .

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. 150n+s/L for this image formation

It receives a yellow line synchronization signal and a video clock, and when the page synchronization signal is "high J, the magenta line synchronization signal is r high", it outputs a magenta image signal, and when the cyan line synchronization signal is "high 1", it outputs a magenta image signal. Similarly, when the yellow line synchronization signal is high 1, 1728 yellow image signals are sent out in synchronization with the video clock for both cyan signals. Furthermore, a strobe signal is generated which is "r high" during the r high 1 period of the magenta, cyan, or yellow line synchronization signal and the video clock is at rest. The enable signal starts from the first cyan line synchronization signal when the page synchronization signal becomes r high 1, and then r high 1 at 1.0ms, 20ms, and 35ws from the rising edge of the cyan, yellow, and magenta line synchronization signals in order.
35ms within the "high j" period of the first magenta line synchronization signal when the page synchronization signal becomes "low"
The process ends when r high j occurs. This enable signal corresponds to the image signal shown in FIG. 9, and corresponds to the energization signal to the heating element 3b. Further, the image forming timing generator 23 generates a light source ON 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, the I
``Repeat high j'' in the order of Oms, 20ms, 35aas.

Furthermore, the image forming timing generator 23 generates a motor reference clock for creating a motor clock to be given to the PLL motor driver 31. This clock is 6 kHz
The motor clock is a continuous clock of Z and is given to the PLL motor driver 31 via a switch controlled by a light source motor ON signal sent from the control section 20 via the interface 21. The recording head 3a takes in a direct signal from an external image signal generator 33 into a shift register inside the head using a video clock from an image forming timing generator 23. This captured image signal is latched into a latch register in the head by a strobe signal from the image forming timing generator 23, and then is latched by an enable signal from the image forming timing generator 23 according to the image signal in the latch register. The heating element 3b is energized, and at the same time the next image signal is taken into the shift register by the video clock. Further, the lighting device 30 for the light B3g receives an AND signal of the ON signal of the light H3g from the image forming timing generator 23 and the light source motor ON signal from the interface 21,
When the signal is high 1, light source 3g is turned on. As shown in FIG. 7, the PLL motor driver 31 drives the light source motor 32a so that the input motor clock and the output from the light receiving member 31 (FIG. 6(A)) are phase synchronized. Furthermore, this PLL motor driver 31 is connected to the control section 2 via an interface 21.
A lock detection signal indicating that phase synchronization is applied to the rotational body 3C is sent to the image forming timing generator 23, and a rotational phase reference signal for synchronizing the rotating body 3C with the line synchronization signal is sent to the image forming timing generator 23.

In this embodiment, the number of light blocking parts 3j3j' on the rotating body 3C is 900, and if the light source motor 32a is in phase synchronization state by the PLL motor driver 31, the motor clock is 6 kHz as described above. Therefore, the rotating body 3C rotates at a speed of 150 ms per revolution. An image is formed on the transfer recording medium 1 by the control described above. Next, conveyance control of the transfer recording medium 1 and the recording paper 8 for transferring the image formed on the transfer recording medium 1 to the recording paper 8 will be explained. The feed motor driver 24a is connected to the interface 2
1, the feeding motor ON signal from the control unit 20 is
When high J, the feed motor 24 is driven and the feed roller 9
Then, the pair of registration rollers 10a and 10b are rotated to convey the recording paper 8 at a constant speed.

Further, the transport motor driver 25a also receives the transport motor O from the control unit 20 via the interface 21.
When the N signal is r high 1, 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 1 and the recording medium 8 are
is transported at a constant speed. Ejection motor driver 26a
Similarly, the discharge motor ON signal from the control unit 20 is “
When high J, the discharge motor 26 is driven and the drive roller 1 is
3a, and also rotates the color mixing roller 15a via a drive transmission system. At this time, as described above, the drive transmission system is set so that the rotational peripheral speed of the discharge belt 13c and the rotational peripheral speed of the color mixing roller 15a are the same speed.

Further, the vibration unit driver 27 controls the vibration unit 16 to ONL and vibrates the color mixing roller 15a in the direction of the arrow f in FIG. Similarly, the charger driver 28 also drives the charger 14a when the discharge motor ON signal is "high 1". Here, the timing of each signal sent by the control section 20 via the interface 21 is as shown in FIG.
Incidentally, the times T, -Ts in FIG. 12 correspond to the distances between each member L, -L, . . . as shown in FIG. 13. In the case of binding, it is the time required for conveying the transfer recording medium 1 or the recording paper 8 as follows.

L1: Conveyance distance of the transfer recording medium 1 from the recording head 3a to the pressure contact portion between the transfer roller 4a and the pressure roller 4b.

L8: Conveyance distance of the transfer recording medium 1 from the pressure contact portion to the peeling roller 5. L,: Conveyance distance of the recording sleeve 8 from the registration sensor 29 to the pressure contact portion.

L4: Conveyance distance of the recording paper 8 from the peeling roller 5 to the drive roller 13a.

T,: transfer recording medium 1 to L, -L. The time required to transport the distance.

T! : Time required to send the record 8 a distance L, aS. T,: Length of record size 8 (for example, 29 for A4 size)
70) The time required to transport the transfer recording medium by 70 minutes. T4: Transfer recording medium 1 to L, +L. The time required to send the distance jiIS. T,: Time required to transport the record 8 a distance L4. 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 29. At this point, the rotating body 3c rotated by the light source motor 32a 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 j" for a time T, and a transfer image forming process is performed in the recording section 3.

The conveyance motor 25 operates during the image forming time. After T has elapsed, it will stop after a further time T 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, and then the feed motor 24 is driven for a time T2 to convey the recording shaft 8 at the same speed as the transfer recording medium 1, and then stops. 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 section 20 that sends out each signal as shown in FIG. do. That is, since the magenta line synchronization signal has a period of 150 m 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, transport motor ON signal, page signal, and discharge 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 configuration as shown in FIG. 14, and consists of a total of 3496 words from the 0th word to the 3496th word. corresponds to the transport motor ON signal, bit 2 corresponds to the page signal, and bit 3 corresponds to the discharge motor ON signal (including the vibration unit ON signal and the charger drive signal).

In addition, the numbers in the box at the top of Fig. 12 indicate the magenta line synchronization signal at the time when the registration sensor signal becomes r high, and the number of the magenta line synchronization signal at each time point (signal number). number). 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 r high 1, and when the signal becomes r high J, the process moves to step S5 and waits for the lock detection signal from the PLL motor driver 27 to become r high. ．． That is, it waits for phase synchronization of the rotating body 3C. When the lock detection signal becomes r high J, the process moves to step S6 and O is substituted into R indicating the rask number of the sequence table. Next, in step S7, the Mazenkline synchronization signal is set to r row 1.
Then, at step $8, wait for the magenta synchronization signal to become r high 16. Thereby, the rising edge of the magenta line synchronization signal is detected.
When the edge is detected, the process moves to step S9, and the Rth bit of the sequence table is referred to, and bit 01
Turn on the feeding motors for Bint 1, Bit 2, and Bint 3 respectively.
It is sent as a signal, transport motor ON signal, page signal, and discharge 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, and if it is larger, the process moves to step 512 to stop the light source motor 32a and end the recording. The image formed as described above is transferred onto the recording paper 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. Thermistors T and t in FIG. 16 are arranged so as to be in contact with the surface of the transfer roller 4a, and the resistance value changes depending on the surface temperature of the transfer roller 4a. is converted into voltage Ex by converter Co and compared with reference voltage E●. The comparison output is connected to the power supply E by relay RL via relay driver Rs.
, controls the energization of the halogen heater 4c. Here, we will discuss the driving principle of the temperature control configuration. Thermistors T and I have 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. Is the resistance value lower? As a result, the voltage E, decreases.

Conversely, if the surface temperature of the transfer roller 4a decreases, the thermistor T
, and the voltage E2 also increases. Therefore, by setting the value of the reference voltage E0 to the value of the voltage E corresponding to the temperature of the transfer roller 4a at 95°C, when the surface temperature of the transfer roller 4a is lower than 95°C, the comparison output becomes ``High 1''. , the halogen heater 4C is energized, and the surface temperature of the transfer roller 4a rises. On the other hand, when the temperature is higher than 95°C, the halogen heater 4C is not energized and the surface temperature decreases.

Due to the above control, the surface temperature of the transfer roller 4a is 90 to 10
It is maintained at 0°C. This control system is constantly operating when the power switch of the apparatus is on, and is controlled so that the surface temperature of the transfer roller 4a reaches 90 to 100 DEG C. before the start button on the operation panel is pressed.

The structure for maintaining the surface of the color mixing roller 15a at 150 to 160''C 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 transfer, the transfer recording medium 1 and the recording paper 8 are separated by the peeling roller 5, the transfer recording medium 1 is wound onto the take-up roll 6, and the recording paper 8 is discharged by the discharge means 13.

When the recording paper 8 is ejected, the recording paper 8 is ejected from the ejection belt t-7.
The discharge belt 13c is charged with a positive charge by the discharge of the charger 14a, and the recording belt 8 is injected with a negative charge by the electrode roller 14b, so that the recording belt 8 is transported by the discharge belt 3c. It is transported in a state in which static electricity is adsorbed.

Furthermore, during the conveyance, pressure and heat are applied to the image transfer surface of the recording sleeve 8 by the color mixing roller 15a, and since the color mixing roller 15a is slightly vibrating in a direction perpendicular to the conveyance direction, the image transfer surface is is subjected to shear force.

When applying the shearing force, the recording paper 8 is moved by the ejection bell H. 3c
Since the color mixing roller 15a vibrates, the recording paper 8 will not be dragged or moved.

Therefore, a stable shearing force is applied to the image transfer surface k. When fixing an image by applying pressure and heat as described above, shearing force is applied to promote the destruction of the capsule-shaped image forming element that forms the image, so that each image forming element is Color mixing is further promoted at the border.

Here, to explain the color mixing state in a simplified manner with reference to the drawings, for example, the blue-purple image transferred to the recording medium 8 by the transfer section 4 is as shown in FIGS. 17(A) and 17(B). A blue image forming element body 17a and a magenta color image forming element body 17b are transferred. When this image passes through the color mixing roller 15a, as shown in FIGS. 18(A) and 18(B), the image forming elements 17a and 17b are destroyed by the application of the pressure, heat and shearing force, and the cover is removed. The ledge is improved, color mixing progresses at the boundary between the image forming elements 17a and 17b, the blue-violet image becomes clearer, and the image quality is improved.

The recording medium 8 on which the image in which color mixing has been further promoted as described above is discharged to υ1 out 1 heley 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 Bib side of the transfer recording medium 1, and the support 1a Although the configuration has been described in which heat is applied according to the image signal for side-swaying, another configuration may be adopted in which heat is uniformly applied and a predetermined light is irradiated in accordance with the image signal.

In addition to the above-mentioned method using the recording head 3a, the heating means may also use a selective heating method using a YAG laser and a polygon mirror, and the light irradiation means may use the above-mentioned rotating body 3c. There is no need to limit the method used.

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 fine. 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 naturally possible to perform one-color recording or two-color recording. (3) Transfer section In the above 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. The transfer section 4 is not limited to a roller-like structure such as the transfer roller 4a and the pressure roller 4b, but may be any structure that can obtain a desired pressure, such as a rotating belt.

(4) Discharge means Although urethane rubber was used for the discharge bell 30 in the first embodiment described above, it is also possible to use other materials such as polyethylene or polyester.

(5) Pressure means In the above-mentioned embodiments, the color mixing roller 15a is rotated at the same circumferential speed as the ejection belt 13c, but the color mixing roller 15a is rotated slightly (for example, about 2%) faster than the ejection belt 13C. Alternatively, the color mixing roller 15a may be set to rotate in the opposite direction to the rotation direction of the discharge belt 13C.

Also, Fig. 19(A). As shown in (B), a cleaning mechanism for the color mixing roller 15a may be provided. 19th
The structure of Figure (A) is that a felt par 18a made of aromatic polyamide resin fibers is coated with 5,000 to 10. O

With the above configuration, the surface of the color mixing roller 15a that has come into contact with the image on the recording paper 8 can be cleaned by the felt parser 18a, and offset of the image forming element can be prevented. Further, in the configuration shown in FIG. 19(B), a cleaning belt 18b 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 15 by a pressure roller 18c. Therefore, the same effect as in the case of FIG. 19(A) can be obtained. Further, in the first embodiment described above, pressure and heat are applied by the pressure means 15, but even if only pressure is applied, destruction of the image forming element is promoted and color mixing is promoted.

(6) Vibration means In the first embodiment described above, the voice coil type vibration unit 16 was used as the vibration means, but instead of this, as shown in FIG. The element 19a may be attached to the color mixing roller 15a, and power may be supplied to the vibrator 19a through a slip ring 19b. In this case, it is preferable to cause 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
Although the HzS vibration was set to 0.31-, it is obvious that the vibration frequency and amplitude of the color mixing roller 15a are not limited to the above values. (7) Recording medium The recording medium is not limited to the above-mentioned recording paper; for example, an overhead projector (OHP)
Of course, plastic sheets etc. for use can also be used.

Effects of the Invention> As described above, the present invention sequentially forms an image on a transfer recording medium and transfers this image to a recording medium, so it can be used even on recording media with relatively low surface smoothness. Images can be recorded well. Also, if the present invention is applied to multicolor recording, what about the recording medium? j! Multicolor images can be obtained without making rough movements. Furthermore, by applying at least pressure to the recording medium on which the 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 improved. Furthermore, when increasing the color mixing, applying shearing force to the image forming surface further increases the degree of color mixing, but at this time, since the recording medium is adsorbed to the ejection means, the shearing force is applied more effectively.
