DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a recording device that can be used in printers, copying machines, facsimile machines, and the like.

<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-mentioned recording devices includes a recording medium uniformly coated with microcapsules encapsulating coloring agents of different colors and reactive substances that undergo a polymerization reaction in response to light of a specific wavelength, and a recording medium that causes a coloring reaction with the coloring agent. There is a recording device that uses recording paper uniformly coated with a color developer.

The recording device uses a photoinitiator that is sensitive only to a specific wavelength, forms an image using an optical signal on a recording medium coated with microcapsules containing the photoinitiator, and forms an image on a recording paper coated with a color developer and the recording medium. The capsule is brought into pressure contact with a medium to destroy the capsule and cause a coloring reaction (US Pat. No. 4399).
No. 209, No. 4416966, No. 800014, etc.).

The recording apparatus has the advantage that color recording can be performed in one shot.

<Problems to be Solved by the Invention> However, the recording apparatus described above is not without its problems.

That is, the average particle size of the microcapsules is as small as about 5 pm, and when the microcapsules are pressed against a recording paper having a thickness of about 60 to 100 pi to destroy the capsules, the microcapsules are absorbed into the fibers of the recording paper. It may become stuck and inhibit the pressure break function.

For this reason, if the recording paper is pressed with high pressure, the recording paper is likely to be damaged, and the recording paper is likely to be wrinkled. In addition, excessive torque is required when the developing roller bites the recording paper, so a roller structure that combines multiple rollers is required to prevent roller deformation and increase rigidity, which may increase the size of the device. There is. Furthermore, there are other problems such as the need for an accurate continuous conveyance technique for the recording medium and the recording paper in the same direction under high pressure.

An object of the present invention is to provide a highly reliable recording device that can easily perform pressure destruction of microcapsules with a simple configuration.

<Means for Solving the Problems> A typical means for solving the above problems in the examples described below is to encapsulate color formers of different colors and a reactant that undergoes a polymerization reaction in response to light of a specific wavelength. A recording medium conveying means for conveying a recording medium having a plurality of types of image forming elements on a support, and a recording medium having a color developer that causes a color reaction with a color former of the recording medium to a developing means. a recording medium conveying means for conveying a recording medium to the recording medium, a recording means for selectively applying optical energy having two or more types of spectral distributions to the recording medium according to an image signal, and Energy applying means for applying energy to promote destruction of the image forming element, and developing means for overlapping the recording medium that has passed through the energy applying means and the recording medium and applying pressure to both. It is characterized by the following.

Still another feature is that the energy applying means is constituted by a vibrating member that makes minute vibrations in contact with the recording medium.

Effect> According to the above means, a multicolor image is formed by selectively applying light energy to the recording medium, and the image is visualized by applying pressure to the recording medium.

In addition, a predetermined energy is applied to the recording medium that has passed through the recording means.
For example, by applying vibration energy by a vibrating member, the image forming element becomes easily destroyed. Therefore, the image forming element can be easily destroyed in the developing means to obtain a multicolor image.

<Example> Next, an example of a recording apparatus to which the above-described means is applied will be described.

．． A blade 5a and a blade roller 5b constituting the energy applying means 5 are passed through a guide roller 3a, a guide plate 3b located opposite the recording means 4, and a guide roller 3C.
, then between a driving roller 6a and a driven roller 6b constituting the developing means 6, and then a peeling roller 7.
, the guide roller 3d changes direction to reach the take-up roll 8, and the tip thereof is locked to the take-up roll 8 by means such as a gripper (not shown).

After setting the recording medium 1 as described above, during recording, by driving and rotating the drive roller 6a while applying torque in the direction of the arrow C to the take-up roll 8 using a known drive means, the recording medium 1 is moved in the direction of the arrow C. The recording medium 1 is fed out in the direction a, and in synchronization with this feeding, the recording means 4 selectively applies light energy of a predetermined wavelength to the recording medium 1 to form an image, and the energy application means 5 destroys the microcapsules of the recording medium 1. After the image is brought into a state where it is easy to print, the image is superimposed on a recording paper 9, which is a recording medium, by the developing means 6, and a predetermined pressure is applied to visualize the image on the recording paper 9. Further, the recording medium 1 after the image is recorded is wound onto a take-up roll 8, and the recording paper 9 is discharged onto a discharge tray 10c by a pair of discharge rollers 10a and 10b.

Incidentally, when conveying the recording medium 1, a certain back tension is applied to the supply roll 2 by existing means,
Due to this tension, the guide rollers 3a, 3c, and the guide plate 3b, the sheet is stably conveyed when passing through the recording means 4.

Next, the configuration of each of the above-mentioned parts according to this embodiment will be explained in detail.

First, as shown in FIG. 2, the recording medium 1 consists of a support la made of a sheet-like polyethylene terephthalate film having a thickness of about 40 prn, and a recording layer 1b that can form an image when light energy of a specific wavelength is applied. It is formed by forming.

To explain an example of this, as shown in FIG.

Cores of this embodiment: l bl, l bx, 1 bs

Specifically, it is composed of components as described in JP-A-62-150242.

For example, in this example, core lb+ is 3-thenoyl 7-ethylaminocoumarin, 2-mercaptohenzuoxazole (MBO), 2. It is composed of components such as 6-diitubropylaniline and React Yellow (BASF).

Core lbz is also comprised of components such as Compound 8A, 2,6-diitupropylaniline, HD5100 (magenta color precursor, from Hilton Davis Chemical).

Additionally, core lbz is comprised of components such as Compound IIA, 2,6-diituprobylaniline, and a cyanogen precursor (CP-117 from Hilton Davis Chemical).

Core 1b+, lbi', It consisting of the above components
) z is coated with a shell lbn of about 1 mm thick made of urea resorcinol-formaldehyde, gelatin, etc., and this is coated with a shell lbn of about 1 mm thick, which is made of urea resorcinol-formaldehyde, gelatin, etc., and this is coated with a shell lbn having a particle size of 2 mm by a known method such as coacervation or liquid-liquid phase separation interfacial polymerization. An image forming element is formed as a microcapsule of 10 plI and an average particle size of 5n. Furthermore, the recording medium 1 is constructed by uniformly coating the image forming element on the support la by means similar to known coating techniques for carbonless paper.

The photoinitiator in the core 1b1 in the image forming element is a third
In the light absorption characteristics shown in the figure, the capsule absorbs light in the band of graph A (420nl11 in terms of peak wavelength), undergoes a polymerization reaction and hardens, and the capsule, which is not irradiated with light and has not undergone a polymerization reaction, turns yellow when it is transferred and recorded. It develops color.

Further, the photoinitiator in the core 1b1 in the image forming element is
Light in the band shown in graph B in the figure (peak wavelength approximately 550n)
(m), undergoes a polymerization reaction and hardens, and capsules that are not irradiated with light and have not undergone a polymerization reaction develop a magenta color during transfer recording.

Furthermore, the photoinitiator within the core lbl in the imaging element is
Light in the band shown in graph C in the figure (peak wavelength approximately 650n)
Capsules that have not undergone a polymerization reaction and are not irradiated with light develop a cyan color during transfer recording.

The recording medium 1 is placed on the support 1 at the position of the recording means 4.
It is set so that the a side is guided by the temporary guide 3b and the recording 151b side faces the recording means 4.

Next, the configuration of the recording means 4 will be explained.

This recording means 4 has a function of forming an image on the recording medium 1. Its structure is as shown in FIG.

In FIG. 1, 4a is a cylindrical rotating body made of glass with a thickness of 2 as, and three types of phosphors A and B are placed on its inner surface.
, C are sequentially applied in the circumferential direction in strips every 120° (divided into three).

The phosphors A, B, and C emit light of different wavelengths, and in this example, the main component of the phosphor A is Ba.
, MgAl+60zCEu (europium activated barium magnesium aluminate) is used. The main components of the phosphor B are LaPoa:Ce and Tb (selenium and terbium activated lanthanum phosphate).

Furthermore, YzCh:Uu (europium activated yttrium oxide) is used as the main component of the phosphor C.

These phosphors A, B, and C emit light from a light source 4b provided inside the rotating body 4a. For example, when a germicidal lamp GL-10 is used as the light source 4b, each of the phosphors A, B, and
The spectral distribution of light emitted by , C is as shown in FIG. That is, phosphor A has a peak wavelength of about 4
The phosphor B emits light with a spectral distribution of 51 nm), and the phosphor B emits light with a spectral distribution of 51 nm), and the phosphor B emits light with a spectral distribution of 543 nm (peak wavelength of about 543 nm).
Phosphor C is shown in graph C in Figure 4 (peak wavelength approximately 611 nm).
) emits light.

Further, the light from the light source 4b is applied to the surface of the light gub by the irradiating portion 4 so that the light from the light source 4b is irradiated only from the linear irradiating portion 4C.
An aluminum film 4d is deposited except for C. Furthermore, the rotating body 4a is housed in a light-shielding housing 4e, and a slit 4f is also formed in the housing 4e at a position corresponding to the irradiation section 4C of the light tA4b. Therefore, an optical path is formed such that the light from the light fi4b passes from the irradiation section 4C, passes through the slit 4f, and is irradiated onto the liquid crystal shutter array 4g.

The liquid crystal shunter array 4g has a pixel density of 8 dots/mm and selectively irradiates light by opening and closing in accordance with an image signal. The light emitted from the liquid crystal shutter array 4g is imaged onto the recording medium 1 on the guide plate 3b by a short focus imaging lens, for example, a Cellhoc lens (registered trademark 411) 4h.

Further, the rotary body 4a is supported at three points on one side near both ends of its outer circumference by one pair of driving rollers 4L and two pairs of driven rollers 412°4is, and the pair of driving rollers 4i+
The rotating body 4a is configured to rotate in the direction indicated by the arrow when the driving roller pair 4iI rotates by a known driving means (not shown), that is, a light source motor connected via a pulley, a timing belt, etc.

With the above configuration, while lighting the light i+1X4b,
When the light source motor is driven to rotate the rotating body 4a, the phosphors A, B, and C are illuminated by light emitted from the irradiation section 4C.
are alternately excited and emit light, and as shown in FIG.
g is sequentially irradiated.

With the above configuration, the light beam is narrowed down and a small to medium-sized light beam with a large amount of light can be obtained. Furthermore, by rotating the rotating body 4a at high speed, light having different spectral characteristics can be switched at high speed.

The rotational speed and phase of the rotating body 4a are controlled so as to be synchronized with the conveyance of the recording medium 1, and for this purpose, the rotating body 4a is configured as follows.

As shown in FIG. 1(B), a large number of light shielding parts 4j are formed in a stripe shape at regular intervals on the circumference near the end of the rotating body 1, and one of the light shielding parts 4j' is Other light shielding part 4
It is formed wider than j. Furthermore, the light shielding part 4j,
A light emitting member 4k such as an LED is disposed on the inside of the rotating body 4a so as to sandwich 4j', and a light receiving member 41 such as a photodiode is disposed on the outside.

In the above configuration, the rotational speed of the rotating body 4a can be determined by detecting the number of changes in the amount of light (pulse number) transmitted from the light emitting member 4k through the light shielding parts 4j, 4j' and non-shading parts of the rotating body 4a using the light receiving member 42. can be detected, and the rotational speed of the rotating body 4a is controlled based on this signal. Further, since there is a wide light shielding portion 4j', the rotational phase of the rotating body 4a is detected by detecting the pulse width of the signal.

By detecting the number of pulses and the pulse width and controlling the drive of the light source motor based on this, the rotating body 4
a is configured to rotate in synchronization with the conveyance of the recording medium 1.

Next, the configuration of the energy applying means 5 will be explained.

The energy applying means 5 has a function of making the image forming element of the image formed by the recording means 4 more likely to be destroyed by the developing means 6.

Specifically, the energy applying means 5 is disposed downstream of the recording means 4 in the conveyance direction of the recording medium l, and
As shown in Figure (B), the width direction of the recording medium 1 (arrow d direction)
It is composed of a blade 5a that serves as a vibrating member that vibrates minutely, and a blade peeler 5b that is in pressure contact with the blade 5a.

The blade 5a is made of stainless steel, and a Langevin type vibrator 5C is disposed at a predetermined position thereof as shown in FIG. The vibrator 5c is driven by a driving means (not shown) and vibrates at a frequency of 35 KHz. This allows the blade 5a to vibrate in the direction of arrow d with an amplitude of 5 ha.

Further, the blade roller 5b is formed of a rubber roller having a rubber hardness of about 40 degrees. This play roller 5b
is configured so that it can be pressed against the blade 5a with a pressure of about 2 kg/- by a pressing means (not shown).

By configuring the energy applying means 5 as described above, shearing force is applied to the recording medium 1 passing between the blade 5a and the blade roller 5b. The image forming element formed on the recording medium 1 is easily destroyed by the action of the shearing force, and is easily destroyed when a predetermined pressure is applied in the developing means 6, which will be described later. It becomes possible to form a visible image.

Next, the configuration of the developing means 6 will be explained.

The developing means 6 has a function of visualizing the image formed by the recording means 4, and is disposed downstream of the energy applying means 5 in the conveying direction of the recording medium l, as shown in FIG. As shown in the figure, it is composed of a drive roller 6a that rotates in the direction of arrow e, and a driven roller 6b that is in pressure contact with the drive roller 6a and rotates as a result.

The drive roller 6a is connected to a transport motor (not shown) via a drive force transmission means, and rotates at a constant speed during recording. This rotation causes the recording medium 1 to be conveyed in cooperation with the driven roller 6b. That is, the driving roller 6a and the driven roller 6b also function as a means for conveying the recording medium 1.

The drive roller 6a is constructed of a carbon steel roller whose surface is hard chrome plated and finished to a predetermined surface roughness (R=0.8 μm in this embodiment).

Similarly, the driven roller 6b has a hard chrome plated surface and has a predetermined surface roughness (R2-0.8μ in this embodiment).
The driving roller 6a is configured to have a pressing force of 25 to 28 kgf/d by a pressing means (not shown) such as a spring.

Further, as shown in FIG. 6, both the driving roller 6a and the driven roller 6b have an outer diameter D1 at the center in the axial direction and an outer diameter D1 at both ends.
2 ((D+>Dz)), and is formed in a shape that tapers parabolically from the center toward both ends.In this example, in FIG. 6, y = -a x" +
236a x +16 (a=1.436 Xl0-6)
(+n) &':, Setting title.

Due to the rollers having the above shape, the pressing force between the two is 25 to 28 k.
Even at a high pressure of gf/c+J, it is possible to maintain a constant pressure distribution in the nip between the driving roller 6a and the driven roller 6b.

Next, a conveying means for conveying the recording paper 9 to the developing means 6 is constructed as shown in FIG. 1(A).

That is, the recording paper 9 is loaded in a cassette 11, and the recording paper 9 is transferred one by one by a feeding roller 12 and a pair of registration rollers 13a and 13b, which are connected to a feeding motor (not shown) via a driving force transmission means. fed, LED14
The leading edge of the fed recording paper 9 is detected by a registration sensor 14 consisting of a phototransistor 14b and a phototransistor 14b, and the feeding timing is controlled so that the image area of the recording medium 1 and the recording paper 9 overlap. The structure is such that the images are fed to the developing means 6 synchronously.

The recording paper 9 is uniformly coated with a color developer 9a that causes a color reaction with the color former of the recording medium 1. In this example, as a color developer, KC-11 (Fuji Photo Film@), as described in JP-A No. 61-24495,
Tamol (Rohm & Haas Chemical Company) Carbon T (Carvon Incorporated)
, DEQuest 2006 (Monsanto Company).

Therefore, the image formed on the recording medium 1 is made visible by the reaction between the color former of the recording medium 1 and the color developer.

As shown in the block diagram of FIG. 7, the control system for operating the recording apparatus having the above configuration includes, for example, a CPU 20a such as a microprocessor, a ROM 20b storing control programs and various data for the CPU 20a, and a CPU 20.
A control unit 20 equipped with a RAM 20c, etc., which is used as a work area for a and also temporarily stores various data.
, interface 21, operation panel 22, registration sensor 14, driver 23a for driving the feeding motor 23, driver 24a for driving the transport motor 24, driver 25a for driving the light source motor 25, light source lighting device 26 , shutter array 4g
, and a driver 27 for driving the vibrator 5c.

The control unit 20 receives various information (for example, recording density, number of recording sheets,
(recorded size, etc.), a signal from the registration sensor 14, and an image signal from an external device 28.

The control unit 20 also connects the feed motors 23 . Conveyance motor 24. Light source motor 25. It generates an ON signal for the vibrator 5c, a light source ON signal, a page signal, and an opening/closing signal for the shutter array 4g in accordance with the image signal.

Each of the above-mentioned members operates according to each of the above-mentioned signals.

Next, a recording method using the recording apparatus configured as described above will be explained.

The conveyance motor is driven to rotate the driving roller 6a and the driven roller 6b to sequentially feed out the recording medium 1 from the roll 2, and in synchronization with this, the light source motor is driven to rotate the rotating body 4.
a is rotated, and the light 114b is made to blink. As a result, the recording medium 1 that is fed out is irradiated with light having respective spectral characteristics according to the yellow, magenta, and cyan image signals to form an image.

When the recording layer 1b is irradiated with light of a predetermined wavelength, it undergoes a polymerization reaction, and the hardness of the reacted image forming element increases. That is,
The fracture resistance of the capsule changes irreversibly, and the capsule has a property of not being destroyed even when pressure is applied by the energy applying means 5 and the developing means 6.

Therefore, as shown in the timing chart of FIG. 8, when recording yellow, when the phosphor A of the rotating body 4a faces the shutter array 4g, the shutter array 4g
are opened and closed according to the yellow image signal, and at the same time, 30m5 of the light sources 4b are turned on. As a result, the light shown in graph A in FIG. 4 is spatially modulated in accordance with the yellow image signal, and its image is formed on the recording layer 1b by the short focus imaging lens 4h.

Next, during magenta recording, when the rotating body 4a rotates and the phosphor B faces the shutter array 4g, the shutter array 4g is opened and closed according to the magenta image signal,
At the same time, the light source 4b is turned on for 30+ns. As a result, the light in graph B in FIG. 4 is spatially modulated in accordance with the magenta image signal, and its image is formed on the recording [1b] via the lens 4h.

Similarly, during cyan recording, when the phosphor C of the rotating body 4a faces the shutter array 4g, the shank array 4g is opened and closed in accordance with the cyan image signal, and at the same time the light source 4b is turned on by 30m5. As a result, the light shown in graph C in FIG. 4 is spatially modulated in accordance with the cyan image signal, and its image is formed on the recording layer 1b via the lens 4h.

In the manner described above, the recording Jllb is irradiated with light according to both yellow, magenta, and cyan signals to form a negative image.
The recording medium 1 is conveyed at a repeating cycle of 180 m5/line.

Here, transport control of the recording medium 1 and the recording paper 9 to visualize the image formed on the recording medium 1 on the recording paper 9 will be explained.

The feed motor driver 23a drives the feed motor 23 when the feed motor ON signal from the control unit 20 via the interface 21 is C high 1, and drives the feed roller 12 and the registration roller pair 13a, 13b. It rotates and conveys the recording paper 9 at a constant speed.

Further, the transport motor driver 248 also receives the transport motor O from the control unit 20 via the interface 21.
When the N signal is "high 1", the conveyance motor 24 is driven to rotate the drive roller 6a, and the recording medium 1 and the recording paper 9 are conveyed at a constant speed by the cooperative action with the driven roller 6b which rotates as a result of this. .

Here, the timing of each signal sent by the control section 20 via the interface 21 is as shown in the ninth section. Note that the times T and ~T4 in FIG. 9 are the distances between each member as shown in FIG. It takes time.

Ll: Conveyance distance of the recording medium 1 from the position of light irradiation on the recording medium 1 by the recording means 4 to the pressure contact portion of the driving roller 6a and the driven roller 6b.

L2; Recording medium 1 from the pressure contact portion to the peeling roller 7
transport distance.

L3: Conveyance distance of the recording paper 9 from the Ni-registration sensor 14 to the pressure contact portion.

Tl; Time required to transport the recording medium 1 a distance of LI L'l.

T2: Time required to convey the recording paper 9 a distance of .

T: Length of recording paper 9 (for example, 29 for A4 size)
7+n) time required to transport the recording medium l.

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

That is, when the operator presses the start button on the operation panel 22, the feeding motor 23 is driven, feeds the recording paper 9, and stops driving when the leading edge of the recording paper 9 hits the registration sensor 14. At this point, the rotating body 4a rotated by the light source motor 25 is controlled to rotate in phase synchronization. Next, the conveyance motor 24 is driven to move the recording medium l along the arrow a in FIG.
At the same time, the page signal becomes "high J" for a time T, and the image forming process is performed in the recording means 4.

Further, the conveyance motor 24 stops after the image forming time T has elapsed and after a further time T has elapsed.

The feed motor 23 is driven for a time T2 after the time T has elapsed since the start of conveyance of the recording medium 1, conveys the recording paper 9 at the same speed as the recording medium 1, and then stops. As a result, the leading edge of the recording paper 9 matches the leading edge of the image formed on the recording medium 1 in the developing means 6, and is conveyed by the drive of the conveyance motor 24 while being in close contact with the recording medium 1.

As the recording medium 1 is conveyed, the recording paper 9 is conveyed so as to overlap the image forming area thereof, and when both are conveyed between the driving roller 6a and the driven roller 6b, both the recording medium 1 and the recording paper 9 are Pressure is applied by rollers 6a, 6b.

By applying the pressure, the image forming element of the recording layer 1b is destroyed depending on the hardness state, as shown in FIG.

When this image-forming element is destroyed, the core inside the capsule flows out, and the flowing color former and the color developer 9a of the recording paper 9 undergo a color reaction and are recorded as a visible image.

When the recording medium 1 is conveyed, vibration energy is applied to the recording medium 1 by the energy applying means 5. This vibration energy is generated by driving the vibrator 5c to vibrate the blade 5a when the vibrator ON signal from the control unit 20 via the interface 21 is "high 1", thereby applying it to the recording medium 1 as a shearing force. It is something that

The image forming element formed on the recording layer 1b of the recording medium 1 becomes easily destroyed by the application of the vibrational energy.

In addition, the image forming element of the recording medium 1 is in a state where it is easily destroyed as described above, and it is possible to obtain a high-quality visible image without applying more than necessary pressure by the driving roller 6a and the driven roller 6b. This makes it possible to prevent wrinkles, scratches, etc. from occurring when the recording medium 1 and the recording paper 9 are transported.

After the visible image is recorded on the recording paper 9 by the developing means 6 as described above, the recording medium 1 and the recording paper 9 are separated by the peeling roller 7, and the recording medium 1 is wound up by the winding roll 8, and the recording medium 1 is Paper 9 is discharged onto discharge tray 10c.

As described above, the recording medium 1 and the recording paper 9 are stably conveyed, and high-quality color recording is performed in one shot.
