Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a recording device that can be used in a printer, a multiple Tg machine, a soaximillimeter, 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 recording devices is a thermal transfer recording device.

In this method, recording is performed on recording paper using an ink ribbon made by coating a ribbon-shaped support with a heat-melt ink consisting of a colorant dispersed in a heat-melt binder.

That is, the ink ribbons are stacked so that their hot-melt ink layer is in contact with the recording paper, and the ink ribbon and the recording paper are conveyed between a heat gutter and a platen, and the heat is applied from the support side of the ink ribbon. By applying pulsed heat corresponding to the image signal in step 7) and transferring the molten ink to the recording paper by pressing them together, an ink image corresponding to the heat application is recorded on the recording paper. It is something.

The second recording device uses a smaller and lighter device, does not cause noise (puff), and can record on 11" paper, and can print images due to differences in OfI characteristics depending on the image signal. We proposed a technology to form the image and transfer it to the recording medium (
Japanese Patent Application No. 60-120080, No. 60-120081, April No. 60-131, No. 60-134831, No. 60-150597, No. 60-199926, etc.).

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.

An object of the present invention is to further develop the above-mentioned technology, and to provide a recording apparatus capable of speeding up recording by subjecting the transfer recording layer to a preliminary reaction.

For this purpose, a typical means according to the embodiments described below is a transfer record consisting of a distributed layer of a plurality of types of image forming elements that exhibit different color tones and whose transfer characteristics change when light energy and thermal energy are applied. It has been widely used in recent years because it can be rotated at the fastest speed by a transport stage for transporting a transfer recording medium having layers and the above-mentioned JX means.

<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 attempting to obtain a multicolor image with a conventional thermal transfer recording device, it is necessary to repeat transfer to avoid overlapping colors. For this purpose, it is necessary to install multiple thermal heads, or to make the recording paper make complicated movements such as stopping and reversing, 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 used a photothermal sensitive material, and when thermal energy and light energy were applied, the reaction of the material progressed to 9fl, and the transfer characteristics became irreversible. The transfer recording performance includes a heating means for applying thermal energy in accordance with image formation, and rotating a plurality of types of phosphors corresponding to the plurality of types of image forming elements and having peak wavelengths in the photosensitive wavelength range. The rotating body is coated in stripes in the direction of the rotational axis of the transfer recording layer, and at least one uncoated area is formed between the plurality of types of phosphors. a recording section having a light irradiation means for applying light energy to the transfer recording layer by flashing a light source that excites the phosphor in accordance with the above, and transferring an image formed in the recording section to a recording medium. This feature is characterized by the provision of a transfer section for the purpose of printing.

<Function> The transfer recording layer has a photothermally sensitive image forming element, and when light energy and thermal energy are applied, the polymerization component in the photothermally sensitive material rapidly polymerizes and hardens. By doing so, the transcription characteristics are irreversibly changed.

Its characteristics are as shown in FIG. 17, for example. In the figure, the solid line in the first quadrant shows the relationship in which the polymerization rate of the polymerization component increases dramatically when both light energy and thermal energy are applied. Also, the 17th
The broken line in the first quadrant of the figure shows the increase in the polymerization rate of the polymerization component when light energy is applied. Further, the second quadrant in FIG. 17 shows the change in transfer temperature as the polymerization rate of the polymerization component increases.

As can be seen from FIG. 17, when light energy and thermal energy are applied to the transfer recording layer over time t2,
The transfer temperature Ta of the transfer recording layer before application increases irreversibly to Te. Therefore, at least one of light energy and thermal energy is made to correspond to recorded information in the transfer recording layer,
By applying the light and thermal energy, a transferred image corresponding to recorded information is formed on the transfer recording layer. Then, the transfer recording layer on which the image was formed and the recording medium are superimposed and T<
If T<Tc is satisfied and transfer is performed at temperature T, a desired transferred image can be obtained on the recording medium.

At the 1711th point, the 1 dJ transfer temperature starts to rise rapidly and shrinkage can be achieved.

<Example> Next, an example of the present invention to which the above means is applied will be described in detail.

[First example]

FIG. 1(8) is a schematic cross-sectional explanatory view of the recording apparatus according to the first embodiment, and FIG. 1(B) is a perspective explanatory view.

In the figure, reference numeral 1 denotes a long belt-like transfer recording medium, which is wound into a roll and used as a supply roll 2 in the apparatus main body M.
It is removably incorporated into the.

That is, this supply roll 2 is removably loaded onto a rotatable shaft 2a provided in the main body M of the apparatus.

First, the leading edge of the transfer recording medium 1 is transferred to the supply roll 2.
The peeling roller 5. It is directed by the guide roller 12c and reaches the take-up roll 6, and its tip is locked to the take-up roll 6 by a lower stage of a burr, par (not shown), or the like. After that, the temperature is a known driving temperature, and N1 is the transfer temperature T.
, where tl indicates the light irradiation time to obtain the polymerization rate N, and indicates the minimum light irradiation time to form a transferred image due to a sudden increase in transfer temperature.

Here, the first quadrant in FIG. 17 shows that the polymerization rate of the polymerization component increases even when only light energy is applied. For example, when only light energy is applied for a time t3, the polymerization rate becomes N3. However, at this polymerization rate, the transfer temperature is i+, before it changes drastically, and the polymerization rate is O.
As in the case of , the transfer temperature is T3. In this state, ie, in order to apply light energy and thermal energy to the transfer recording layer with a polymerization rate of N3 and cure it to a polymerization rate of N2 as in the above example, the light irradiation time (t, -t3') is sufficient.

Therefore, it is shorter than the time t2 for increasing the polymerization rate from O to N2 by applying light energy and thermal energy.
It only takes a while.

Therefore, if the polymerization rate of the transfer recording layer is increased in advance within a range where the transfer temperature of the transfer recording layer does not rise rapidly before forming a transfer image, the transfer image can be formed. By rotating the transfer roller 4a while applying a torque of 1~1 to the take-up roll 6 in the direction of the arrow C using a short stage of 5 hours of energy and thermal energy, the transfer recording medium 1 is moved in the direction of the arrow a. move in the direction.

In synchronization with this feeding, the recording unit 3 transfers the transfer recording medium 1
An image is formed by selectively applying thermal energy and light energy of a predetermined wavelength to the recording paper 8, which is overlapped with the recording paper 8 as a recording medium in the transfer section 4, and the image is transferred to the recording paper 8 by applying heat and pressure. Transfer to. Further, the transfer recording medium 1 after image transfer is wound up on a take-up roll 6, and the recording paper 8 is discharged onto a discharge tray 11 by a pair of discharge rollers 13a and 13b.

Incidentally, when winding up the transfer recording medium J, a certain hack tension is applied to the supply roll 2 by 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 part will be explained in detail.

First, the transfer recording medium 1 is created by applying both thermal energy and light energy onto a sheet-like support lc as shown in FIG.
It is formed by depositing a transfer recording layer 1b which has the property of forming an image when applied.

To explain an example thereof, as shown in FIG. 2, the transfer recording layer 1b has the components shown in Table 1 below as the core 1c, the components shown in Table 2 as the core ld, and the components shown in Table 3 as the core 1e. A microcapsule-shaped image forming element is formed using the following method.

Value 13. A few drops of Sanyo Chemical Industries, Ltd.) and 1 g of gelatin were mixed in 200 ml of water and emulsified by stirring at 8,000 to 10,000 rpm with a homomixer at 60° CJJ [1] to form oil droplets with an average particle size of 26 μm. get.

Stirring is continued for an additional 30 minutes at 60"C, with each distillation of methylene chloride resulting in an average particle size of approximately 10 .mu.m.

Add 20mR of water in which 1g of gum arabic was dissolved,
A microcapsule slurry is obtained by adding Nl+4011 (ammonia) water while cooling slowly to bring the pH to less than 1+, and slowly adding 1.0 ml of a 20% glutaraldehyde aqueous solution to harden the capsule walls.

After that, solid-liquid separation was carried out in a Nusoche IJ vessel, and then in a vacuum dryer for 3
It is dried at 5° C. for 110 hours to obtain a microcapsule-shaped image forming element.

This image forming element has core Ic, 1 shown in Tables 1 to 3.
6. Microcapsules are formed in which lc is covered with shell 1f, and the particle size is 7 to 15 μm, with an average particle size of about 10 μm.

The image forming element formed in this way is used as a support l,]
Transfer recording medium (10 g of the components shown in Table 2, that is, Tables 1 to 3 above) was first mixed with 20 parts by weight of methoxychloride (1 g of adhesive). A nonionic surfactant (trade name Noniball 10011 L 8 bodies 1 is obtained.To explain this in more detail, for example, polyester adhesive polyester manufactured by Nippon Gosei Kagaku Kogyo Co., Ltd.), P
1 g of an adhesive prepared by dissolving 3 cc of toluene in -022 (solid content 50%) lee is applied onto a support lc made of a polyethylene terephthalate film with a thickness of 6 μm. Thereafter, the solvent is removed by drying to a thickness of about 1 μm. Since 1 g of this adhesive has a glass transition point of 115°C, a slight tack remains even at room temperature, and the image forming element formed as described above can be easily attached to the support 1a. becomes.

Next, a microcapsule-shaped image forming element using the core material as shown in Tables 1 to 3 obtained as above]:
Mix at a ratio of 1:1 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 was firmly fixed on the support Ja by applying a pressure of about 1 kgf/cffl 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 has a band (picture length 298
The photoinitiator in the image forming element shown in Table 2 starts a reaction by absorbing light of 1 nm) and starts a reaction, and becomes magenta in 8 hours of image formation. The photoinitiator in the image forming element shown in Table 3 starts a reaction by absorbing light with a wavelength of 389 nm (wavelength: 389 nm), and becomes cyan when forming an image. It absorbs light with a wavelength of 458 nm 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. and a light irradiation means for applying the light.

The heating means has a width of 0.2 mm and generates heat on the surface of the recording head 3a according to the image signal, and has a width of 8 tons) / *** △

J, +: Eu (europium-activated strondium magnesium birophosphate) is used, and the main components of the phosphor C are Ba and MgAIILOz7.liu (europium-activated barium magnesium aluminate).

There is light if! inside the rotating body 3c. 3g is disposed, and the phosphors A, B, and C are configured to emit light when the light rX3g is turned on. In this example, the light tA
As 3g, a Toshiba germicidal lamp GL-20 was used,
When this light source 3g is turned on, the phosphor A changes to graph A in Figure 5.
(peak wavelength 335 nm), phosphor B emits light having a spectral distribution as shown in graph B (peak wavelength 390 nm) in FIG. 5, and phosphor C emits light having a spectral distribution as shown in graph C (peak wavelength 450 nm) in FIG. The light emitted by the phosphors A, B, and C is transmitted through a 0.5 mm width sulin) 3 formed on the light shielding plate 3h.
The transfer recording layer 1b is irradiated through the beam i. In addition, in the non-coated area, the light from the light source 3g passes through the rotating body 3 (, 111

The image signal is emitted from a control unit of a facsimile, an image scanner, an electronic blackboard, etc., 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. As shown in Fig. 1 (Δ) and (B), this light irradiation means has a thickness of 2 mm and an inner diameter of 4 mm.
(A rotating body 3C made of a quartz glass cylinder is rotatably supported by three pairs of rollers 3d, 3e, and 3f, and is configured to rotate at a constant speed by driving and rotating the rollers 3d by a motor. ing.

Moreover, on the inner surface of the rotating body 3C, there are marks shown in FIGS.
), three types of phosphors A, B, and C are applied in a stripe pattern at 90 degrees (equally divided into four) in the circumferential direction, and phosphor is applied between phosphors A and C. A non-coated area is formed.

through which the transfer recording layer 1b is directly irradiated.

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 from the light source 3g that has passed through the non-coated area is irradiated, and each Light having different spectral distributions passes through the slit 31 and is sequentially irradiated onto the transfer recording layer 1b.

The light from the light source 3g that has passed through the non-coated area causes all of the three types of image forming elements of the transfer recording layer 1b to react. Therefore, when the non-coated area faces the slit 31, the light source 3g is turned on for a predetermined period of time, and all the heating elements are made to generate heat for a predetermined period of time, thereby imparting a predetermined amount of light and thermal energy to the transfer recording layer 1b. By doing so, all the image forming elements of the transfer recording layer 1b can be preliminarily reacted.

As described above, the predetermined time period for turning on the light source 3g and causing the heat generating element to generate heat is within a range where the transfer temperature of the transfer recording layer 1b does not rise rapidly, that is, within a range where the transfer characteristics do not change. It goes without saying that the time should be set long enough for the first 5 hours.

By sequentially irradiating light from the phosphors A and BC after the preliminary reaction, the transfer recording layer 1b is made to react in accordance with the image signal, and an image can be formed.

The rotating body 3c is set to rotate once for one raster recording, and a control configuration for controlling the rotational speed and phase of this rotating body 3c will be explained.

As shown in FIG. 1 (TI), the rotating body 3c has a large number of light shielding parts 14a formed in stripes at regular intervals on the circumference near the end, and one light shielding part 14a' of the light shielding parts 14a' is formed on the circumference near the end. It is formed wider than the light shielding part 14a. Further, L
A light emitting member 14b such as D is disposed, and a light receiving member 14c such as a photodiode is disposed on the outside.

From the configuration described in section 1iii, the signal obtained from the light receiving section +J'14c is as shown in FIG. 6 (8) when the rotating body 3c is rotating at a constant speed. Incidentally, during the period shown in FIG. 6(A), the phosphor C may be controlled so as to face each other, and this may be repeated in sequence for the enable signal r high J.

Therefore, in this embodiment, PLL (Phase Lo) is used to rotate the rotating body 3c at a constant speed and phase.

Corresponds to 028. The light source motor 28a is a motor that drives the roller 3d that supports the rotating body 3c, and the FG 28b is the output of the light receiving member 14C.

In this embodiment, the phase comparison output of the output of the FG 28b and the motor clock is obtained from the phase comparator 27a, and in order to further stabilize the system, the output of the FG 28b is integrated by the monostable multi-high break 27b, and the output and the phase The level "Low J" indicates the difference in the output of the comparator through a low-pass filter.
The level "High J" is the state where light is received at the light shielding part tJ.
The light is blocked by i4a and is not received by the light receiving member 14c.

Therefore, the frequency of the rising edge of the signal appears as the rotational speed of the rotating body 3C, and by detecting and controlling this, it becomes possible to control the rotational speed of the reversing body 3C.

In addition, when controlling the phase, when the integral waveform of FIG. 6(A) is obtained, it becomes as shown in FIG. 6(B), and since one of the light shielding parts 14a (142i) is wide, the integrated wave height value of that part is high. Therefore, based on the timing when the peak value becomes quotient, the magenta line synchronization signal, cyan line synchronization signal, yellow line synchronization signal, video clip, etc., which will be described later, are

Also, in FIG. 7, the lock detector 27e is the phase comparator 27a.
This is to detect whether the system is in a synchronous state from the signals from the Also, the output of FG28b is the integrator 27f
The waveform (corresponding to FIG. 6(i)) is shaped by a waveform shaper 27g to obtain a rotational phase reference signal.

Next, the 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 the arrow as shown in FIG. 1, and the transfer row 4a. and a pressure roller 4b that rotates as a result of rotation.

The surface of the transfer roller 4a has a thickness of lmya and a hardness of 70.
It is made of aluminum solder covered with silicone rubber, and its surface is maintained at 90 to 100°C by a built-in 800W Haloken heater 4c.

The pressure roller 4b is made of an aluminum roller coated with silicone rubber having a hardness of 70 degrees, and has a pressing force of 6 to 7 kgf/cm with the transfer roller 4a by pressure means (not shown) such as springs. is set to be.

Further, as shown in FIG. 1(A), recording paper 8, which is a recording medium, is loaded in the cassette 7, and this recording paper 8 is transferred to the feeding roller 9. The registration roller pair 10a] Ob feeds the sheets one by one, and the LED 26a and phototransistor 2
By detecting the leading edge of the recording paper 8 being fed by a registration sensor 26 consisting of a registration sensor 6b and controlling the feeding timing, the same 1... It is configured such that it is then fed to the transfer section 4.

Therefore, in the transfer section 4, pressure and heat are applied to the transfer recording medium 1 and the recording paper 8 when they pass between the rollers 4a and 4b.

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 timing chart I in FIG.
When recording magenta color, the heating element 3 corresponding to the complementary color of magenta of the image signal, that is, the green image signal, is selected from among the heating element rows.

The strobe signal from 23 is launched into the lano register in the latch register, and then the heating element 3b is energized according to the image signal in the latch register by the enable signal from the image forming timing generator 23, and at the same time as the energization, the heating element 3b is shifted. The next image signal is taken into the register by the video clock.

Further, the lighting device 29 of the light source 3g receives the ON signal of the light source 3g from the image forming timing generator 23, and lights the light source 3g when the light source ON signal is [high J].

As shown in FIG. 7, the PLL motor driver 27 receives the input motor clock and the light receiving member 14c.
The light source motor 28a is driven so as to be in phase synchronization with the output from (FIG. 6(A)). Furthermore, this P L L
The motor driver 27 sends out a detection signal to the control unit 20 via the interface 21 to notify that phase synchronization is applied, and to the image forming timing generator 23, the rotation body 3C is synchronized with the line synchronization signal. The rotational phase reference I1X'-shift is sent out to match the rotational phase.

The recording medium 1 and the recording paper 8 are conveyed at a constant speed.

Here, the timing of each signal sent by the control section 20 via the interface 21 is as shown in FIG.

Incidentally, when the time T and ~T in FIG. 11 are calculated by taking the distance between each member as shown in FIG. This is the time required for

(2) 1: Conveyance distance of the transfer recording medium 1 to the recording contact point 3a to the pressure contact portion between the copying roller 4a and the pressure roller 4b.

L2: Conveyance distance of the transfer recording medium (2) from the pressure contact portion to the peeling roller 5.

L3: Conveyance distance of the recording paper 8 from the registration sensor 26 to the pressure contact portion.

T1: Time required to transport the transfer recording medium 1 a distance of -L3.

T2: Time required to convey the recording paper 8 a distance of L3.

T3: Length of recording paper 8 (for example, 2 if A4 size)
97 mm) L-1 Transfer recording medium 1 is transferred to the rotating body 3.
The number of light shielding parts 14a and 14a' on C is 720,
When the light source motor 28a is in phase synchronization with the PLL motor toe line \-27, the motor clock is 6 kllz as described above, so the rotating body 3C rotates at a speed of 120 m5 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 24 is connected to the interface 21
When the feed motor ON signal from the control unit 20 is r high J, the feed motor 30 is driven, and the feed roller 9 and registration roller pair 10a, 10b are rotated to rotate the recording paper 8.
is transported at a constant speed.

Further, when the conveyance motor ON signal from the control unit 20 via the interface 21 is "high," the conveyance motor driver 25 drives the conveyance motor 31 to rotate the transfer roller 4a, and the transfer motor driver 25 drives the conveyance motor 31 to rotate the transfer roller 4a. Pressure roller 41
), the time required for the transfer to occur.

T4: Time required to transport the transfer recording medium 1 a distance of Ll + L2.

That is, when the operator presses the Sufu-1 button on the operation panel 22, the feeding motor 30 is driven, feeds the recording paper 8, and stops driving when the leading edge of the recording paper 8 touches the registration sensor 2G. At this point, the rotating body 3C rotated by the light source motor 28a is phase-synchronized by the control described above. Next, the conveyance motor 31 is driven to move the transfer recording medium 1 toward the direction indicated by the arrow a in FIG.
At the same time, the page signal becomes "high" during time T3, and a transfer image forming process is performed in the recording section 3.

The conveyance motor 31 stops after the image forming time T3 has elapsed and further after a time T4 has elapsed.

The feed motor 30 is driven for a time T2 after the time T has elapsed since the transfer recording medium 1 started to be conveyed, and the feeding motor 30 conveys the recording paper 8 at the same speed as the transfer recording medium 1, and then stops. As a result, the leading edge of the recording paper 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 31 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 Mazenkline jUl signal has a period of 120 m5 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. 13 inside, and after Regime 1 - Senry - Shingetsu becomes r high j, the sequence table is sequentially referred to while counting the magenta line synchronization signal, and the feed is started. A motor ON signal, a transport motor ON signal, and a vane signal are sent, and the drive of each member is controlled by each signal.

In this embodiment, the sequence table has a 3-pino I-configuration as shown in FIG.
It consists of 3217 words in total, including bits 0 and 1.
Once the feed is turned on, No. 1 and No. 1 wait for the first general J sumo (S8). As a result, the rising edge of the Mazenkline 1/1 signal is detected. When the edge is detected, the Rth position of the sequence table is referred to and the focus bits 0 to 2 are sent out as a feed motor ON signal, a transport motor ON signal, and a page signal, respectively (S9). Next, add 1 to the value of R (SIO), and the value of R becomes 32.
16 (311), and if the value of R is less than or equal to 3216, step S7
to continue recording, and if it is large, light source motor 2
7a is paused (Sl, 2) to end the recording.

The image formed as described above is transferred to the recording paper 8 by applying heat and pressure in the transfer section 4.

Here, the temperature control configuration in the transfer section 4 is configured as shown in FIG. 15.

The thermistor 33 in FIG. 15 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. is converted into voltage E2 by: 1 inverter 35, reference voltage E, and ter ON signal, HIRA I
・2 corresponds to the page signal.

In addition, the numbers in parentheses in the second part in Fig. 11 indicate that the magenta line synchronization signal at the time when the register I/sensor signal becomes r high j is number 0, and the magenta line at each This shows the synchronization signal number (number of signals).

Next, a series of operations of the control unit 20 having the above-mentioned functions will be explained using the flowchart of FIG.
1) If pressed, sends out a feed motor ON signal and a light source motor ON signal (S2, 33). Next, wait until the registration sensor signal becomes "high j" and wait until the lock detection signal from the PLL motor driver 27 becomes "r high j", that is, wait for the phase synchronization of the rotating body 3C, and then change the sequence table. R without showing rask number
O is substituted into (34-S6).

Next, the magenta line synchronization signal is r row 41.
Rochi (S7), L, and then ``High J'' are compared.The comparative output beam is transmitted to the Rhino \-36, and the relay 37 controls the energization of the halogen heater 4C from the electric wire #E3.

Here, the driving principle of the temperature control configuration will be described. The thermistor 33 has a property that its resistance value decreases as the temperature rises. Therefore, as the surface temperature of the transfer roller 4a increases, the resistance value of the thermistor 33 decreases, and the voltage E2 decreases. Conversely, if the surface temperature of the transfer roller 4a decreases, the thermistor 33
When the resistance value of E2 becomes -9, the voltage E2 also decreases. Therefore, the reference voltage E. By setting the value of voltage E2 to the value of voltage E2 corresponding to transfer roller 4a at 95°C, when the surface temperature of transfer roller 4a is lower than 95°C, the comparison output becomes “High J”.
, the halogen heater 4C is energized, and the transfer roller 4
The surface temperature of a is 2 parts. 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.
It is held at ~100'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°C before the star l button on the operation panel is pressed. Ru.

After the image has been transferred as described above, the transfer recording medium 1 and the recording paper 8 are separated by the peeling cooler 5, and the recording paper 8 on which the image of the desired color has been recorded is delivered to the discharge port 3a, 13
b is discharged to the discharge tray 11. Further, the transfer recording medium 1 is taken up by a take-up roll 6.

As described above, color recording is performed in one shore 1.times. and at high speed.

Here, a comparative example will be shown in which the transfer recording layer [b] was recorded without performing a preliminary reaction.

In place of the rotating body 3C used in the above-mentioned embodiment, one phosphor AB and one fluorescent material C were added at each 120 degrees (equally divided into three) in the circumferential direction of the rotating body.
The first coating is applied quickly, using a rotating body with no non-coated areas.
An image was formed by applying light energy and thermal energy at the timing shown in the timing chart of FIG.

That is, in the same way as in the above-mentioned embodiment, in the recording section 3, a 15 m5 area corresponding to the magenta color is transferred to the recording medium, and a cyan color (1) is transferred to the recording medium. An example has been shown in which an image is transferred and recorded onto the recording paper 8 by changing the softening point temperature of the transfer recording layer 1b made of a polymeric material containing It is also possible to perform transcription recording.

Alternatively, the transfer recording medium 1 is provided with a layer that imparts color development to the recording paper 8 and changes the color development characteristics of the recording paper 8, and the image formed on the transfer recording medium 1 is transferred to the recording paper 8. The configuration may be such that an image is obtained by doing this.

In addition to the above-mentioned polyethylene terephthalate, for example, polyamide, polyimide, capacitor paper, cellophane paper, etc. can also be used as the material for the support [a].

Further, the image forming element forming the transfer recording layer 1b contains a sensitive component and a coloring component, and the sensitive component contains a plurality of energies such as light and thermal energy (=t-

Light energy and thermal energy of 15 m5 were applied to a portion corresponding to 2 m5 of yellow color, and the repetition period of one line was also set to 120 m5 as in the above-mentioned example.

In this case, unlike the above-mentioned embodiment, the transfer recording
Since no preliminary reaction was performed, some fogging was observed on the recording paper 8. Therefore, in the recording unit 3, light energy and thermal energy of 30 m 5.25 m 5.20 m 5 are applied to the parts corresponding to the magenta, cyan, and yellow images, respectively, to form an image, and the lines are repeated. When recording was performed with a period of 150 m5, images without fogging etc. could be obtained as in the above-mentioned embodiment.

As can be seen from this, in the above-mentioned example, since the transfer recording layer 1b was pre-reacted, it was possible to record 30 m5 faster per inch than in the comparative example. It is.
