Abstract

PURPOSE:To facilitate the treatment of jamming and to prevent the generation of image turbulence by a method wherein the first member of a developing means is arranged on the side of the first housing and the second member thereof is arranged on the side of the second housing and a recording medium is fed by predetermined quantity when the first and second housing are closed by the signal from the aforementioned first housing. CONSTITUTION:When a recording medium 1 generates jamming, a latch is released and the first housing M1 is rotated to be opened. Since guide rollers 3a, 3c, 3d and a guide plate 3b are provided in the first housing M1, the feed route of the recording medium 1 is largely opened. Further, the drive roller 5a and follower roller 5b of a developing means 5 are separated largely from each other and the pressure contact state of both rollers is also released and the recording medium 1 is exposed to make it possible to easily treat jamming. When the first housing M1 is closed after the treatment of jamming, a reset switch 15 detects this state and a control part sends out a signal upon the reception of the detection signal to drive a feed motor 24 by definite quantity.

It is structured to convey information.

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

First, the recording medium 1 has a recording layer that can form an image when light energy of a specific wavelength is applied on a support la made of a sheet-like polyethylene terephthalate film with a thickness of about 40 mm, as shown in FIG. 1b.

An example of this is shown in FIG.
b is formed by forming a microcapsule-shaped image forming element body using cores 1 b+, 1 bx, and 1 bt.

The cores 1b+, lbt, and lbi of this embodiment each contain a photoinitiator that is sensitive only to specific wavelengths A, B, and C as shown in FIG. 3, a monomer, a leuco dye as a coloring agent, a stabilizer, etc. It is made up of additives.

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

For example, in this example, the core 1b+ contains 3-thenoyl 7-ethylaminocoumarin, 2-mercaptobenzoxazole (MBO), 2. It is composed of components such as 6-diitubropylaniline and React Yellow (BASF).

Core tb is compound 8A, 2.6 diisopropylaniline, HD5100 (magenta color precursor,
(from Hilton Davis Chemical).

Further, the core lbz is composed of components such as Compound IIA, 2,6 diisopropylaniline, and cyanogen precursor [t (CP-117 from Hilton Davis Chemical).

Core 1b+, lbz, lbs consisting of the above components
is coated with a shell LBN of about 1 pm thick made of urea resorcinol-formaldehyde, gelatin, etc., and this is coated with a shell LBN of about 2 to 10 pm in average particle size by a known method such as coacervation or liquid-liquid phase separation interfacial polymerization. The image forming element is formed as a microcapsule with a particle size of about 5-. 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 1b+ in the image forming element is a third
In the light absorption characteristics shown in the figure, it absorbs light in the band shown in the graph (420 nm in terms of peak wavelength), undergoes a polymerization reaction, and is cured.
Capsules that are not irradiated with light and have not undergone a polymerization reaction develop a yellow color during transfer recording.

Further, the photoinitiator in the core 1b+ in the image forming element is the third
Light in the band shown in graph B (peak wavelength 550n)
Capsules that are not irradiated with light and do not undergo a polymerization reaction develop a magenta color during transfer recording.

Furthermore, the photoinitiator in the core 1b+ in the image forming element is
Light in the band shown in graph C (peak wavelength: 650r)
+m ), undergoes a polymerization reaction and hardens, and capsules that are not irradiated with light and do not undergo a polymerization reaction 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.
The a side is guided by the temporary guide 3b, and the recording Fflb side is set so as to face the recording means 4.

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

In FIG. 1, 4a is a cylindrical rotating body made of glass with a thickness of 21 mm, and three types of phosphors A, B,
C is applied sequentially in the circumferential direction in strips every 120° (divided into three equal parts).

The phosphors A, B, and C emit light of different wavelengths, and in this example, the main component of the phosphor A is 8a.
, MliAl+JiCuu (europium activated barium magnesium aluminate) is used. The main component of phosphor B is LaPom:Ce+Tb(
selenium, terbium-activated lanthanum phosphate). Furthermore, Yz(h:Eu (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 sterilizing Radip GL-10 is used as the light a4b, 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 4
Phosphor B emits light with a spectral distribution of 51 nm), phosphor B emits light with a spectral distribution of 543 nI11 in graph B in Figure 4, and phosphor C emits light with a spectral distribution of 543 nI11 in graph C in Figure 4 (peak wavelength 611 nm).
nn+) light is emitted.

Further, the surface of the light source 4b is provided with the irradiation portion 4c so that the light from the light s4h is irradiated only from the line-shaped irradiation portion 4c.
Aluminum except! ! 4d is deposited. Further, the rotating body 4a is housed in a light-shielding housing 4e, and the housing 4e is also provided with a slit member 4f at a position corresponding to the irradiation section 4c of the light #4b.

Therefore, the light irradiated from the irradiation part 4c of the light source 4b and emitted in B and C to each phosphor passes through the slit formed in the slit member 4f,
An optical path is formed so that the beam is illuminated.

The liquid crystal shutter array 4g is 8 dotS/+w+
It has a pixel density of s, and selectively irradiates light by opening and closing according to the 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, such as a SELFOC lens (registered trademark) 4h.

Further, the rotating body 4a has only one driving roller pair 4++ and two driven roller pairs 4iz near both ends of the outer periphery.

When the driving roller pair 411 is rotated by a known driving means (not shown), that is, a light source motor connected to the driving roller pair 4L via a pulley, a timing belt, etc., the rotating body 4a is configured to rotate in the direction indicated by the arrow.

With the above configuration, when the light fi 4b is turned on and the light source motor is driven to rotate the rotating body 4a, the phosphors A, B, and C are alternately excited and emit light by the light irradiated from the irradiation section 4C, and the fourth As shown in the figure, light having different spectral characteristics passes through the slits of the slit member 4r and is sequentially irradiated onto the liquid crystal shutter array 4g.

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 stripes at regular intervals on the circumference near the end of the rotating body 1, and one light shielding part 4j' of the light shielding parts 4j' 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 the rotating body 4j', and a light receiving member 4R such as a photodiode is disposed on the outside.

In the above configuration, the rotational speed of the rotating body 4a is 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 41. 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.

The rotating body 4 is detected by detecting the number of pulses and the pulse width and controlling the driving of the light source motor based on the detected pulse number and pulse width.
A is configured to rotate in synchronization with the conveyance of the recording medium l.

Next, the configuration of the developing means 5 will be explained.

The developing means 5 applies pressure to the recording medium 1 and the recording paper 8 in order to visualize the image formed by the recording means 4, and presses the first member and the second member. , the recording medium 1 and the recording paper 8 are sandwiched between both members and pressure is applied.

In this embodiment, a drive roller 5a, which is a first member that is disposed downstream of the recording means 4 in the conveyance direction of the recording medium 1 and rotates in the direction of arrow d as shown in FIG. It is configured by a driven roller 5b, which is a second member that is in pressure contact and rotates as a result.

The drive roller 5a 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 5b. That is, the driving roller 5a and the driven roller 5b also function as a means for conveying the recording medium 1.

The drive roller 5a is constructed of a carbon steel roller whose surface is hard chromed and finished to a predetermined surface roughness (R,=1.6p11 in this embodiment).

Similarly, the driven roller 5b has a hard chrome-plated surface and has a predetermined surface roughness (in this embodiment, R is -1.6 m).
The first roller consists of a roller made of carbon steel with a
As shown in the figure, a pressurizing machine 50b can be rotated around a shaft 50a.
is rotatably attached to. Furthermore, the pressure plate 50
b is biased toward the drive roller 5a by a spring 50c to constitute a pressure means, and is configured to come into pressure contact with the drive roller 5a by this pressure means.

Further, as shown in FIG. 5, both the driving roller 5a and the driven roller 5b have an outer diameter D at the center in the axial direction, and an outer diameter D at both ends.
2 (DI>D), and is formed in a shape that tapers parabolically from the center toward both ends.In this example, in FIG. 5, y=-ax"+ 23
6a x +16 (a = 7.1818X10-')
(1st letter) is set.

Due to the rollers having the above shape, the pressing force between the two is 400 to 42
Even at a high pressure of 0 kgf/cffl, a uniform pressure distribution can be obtained in the nip between the driving roller 5a and the driven roller 5b.

Next, a conveying means for conveying the recording paper 8 to the developing means 5 is constructed as shown in FIG. 1(A).

That is, the recording paper 8 is loaded in the cassette θ, and the recording paper 8 is connected to a feeding motor (not shown) and a feeding roller 11 and a pair of registration rollers 1 connected via a driving force transmission means.
The sheets are fed one by one by 2a and 12b, and the LED 13a
detecting the leading edge of the fed recording paper 8 by a registration sensor 13 consisting of a phototransistor 13b and a phototransistor 13b;
By controlling the feeding timing, the image area of the recording medium 1 and the recording paper 8 are synchronously fed to the developing means 5 so that they overlap.

Therefore, in the developing means 5, when the recording medium 1 and the recording paper 8 pass between the driving roller 5a and the driven roller 5b, the pressure of the above-mentioned pressure distribution is applied.

Incidentally, the recording paper 8 is uniformly coated with a color developer 8a 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-61-24495,
Tamol (Rohm & Haas Chemical Company) Carbon T (Carvon Incorporated)
, DEQuest 2006 (Monsanto Company)
It consists of a mixture of.

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. 6, 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.
20a, a control unit 20 equipped with a RAM 20c for temporarily storing various data, etc., an interface 21, an operation panel 22, a registration sensor 13, a driver 23a for driving a feeding motor 23, It consists of a driver 24a for driving the II transmission motor 24, a driver 25a for driving the light source motor 25, a light source lighting device 26, a shutter array 4g, and a reset switch 15.

The control unit 20 receives various information (for example, recording density, number of recording sheets,
(recorded size, etc.), a signal from the registration sensor I3, a signal from the reset switch 15, and an image signal from the external device 27. The control unit 20 also connects the feed motors 23 . Transport motor 2
4. It generates an ON signal for the light source motor 25, a light source ON signal, a page signal, and an opening/closing signal for the shutter array 4g according to 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 transport motor 24 is driven to rotate the driving roller 5a and the driven roller 5b to sequentially feed out the recording medium 1 from the roll 2, and in synchronization with this, the light source motor 25 is driven to rotate the rotating body 4a and the light source 4b is rotated. flash. As a result, the recording layer 1b of the recording medium 1 that is fed out
An image is formed by irradiating light having respective spectral characteristics in accordance with yellow, magenta, and cyan image signals.

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

Therefore, as shown in the timing chart of FIG. 7, 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, for magenta recording, when the rotating body 4a rotates and the phosphor B faces the shutter array 4g, the g-shackle array 4g is opened and closed according to the magenta image signal, and at the same time the light source 4b is turned on for 30a+s. . As a result, the light shown in graph B in FIG. 4 is spatially modulated in accordance with the magenta image signal, and its image is formed on the recording layer 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, 30 m5 of the light 'fA4b is turned on. 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 recording ilb via lens 4h.

In the manner described above, the recording i1b is irradiated with light according to the yellow, magenta, and cyan image signals to form a negative image, and 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 8 in order to visualize the image formed on the recording medium 1 on the recording paper 8 will be explained.

The feed motor driver 23a receives a feed motor ON signal from the control unit 20 via the interface 21. At high j, the feed motor 23 is driven to rotate the feed roller 11 and the registration roller pair 12a, 12b to convey the recording paper 8 at a constant speed.

Further, when the 1st feed motor ON signal from the control unit 20 via the interface 21 is "high 1", the transport motor driver 24a drives the transport motor 24 to rotate the drive roller 5a and follow this. The recording medium 1 and the recording paper 8 are conveyed at a constant speed by cooperation with the rotating driven roller 5b.

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 and -T4 in Fig. 8 are the times required for conveying the recording medium l or the recording paper 8 as shown below, assuming that the distance between each member is L1 to L as shown in Fig. 9. It's time.

Ll: Conveyance distance of the recording medium 1 from the position where the recording medium 1 is irradiated with light by the recording means 4 to the pressure contact portion between the driving roller 5a and the driven roller 5b.

Lt: Recording medium 1 from the pressure contact portion to the peeling roller 6
transport distance.

L3 Conveyance distance of the recording paper 8 from the Ni-registration sensor 13 to the pressure contact portion.

Tl: Time required to transport the recording medium 1 a distance of -L.

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

T3: Length of recording paper 8 (for example, 2 for A4 size)
The time required to convey the recording medium 1 by 97 mm).

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

That is, when the operator presses the start button on the operation panel 22, the feeding motor 23 is driven, feeds the recording paper 8, and stops driving when the leading edge of the recording paper 8 touches the registration sensor 13. 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 1 along the arrow a in FIG.
As the paper is transported in the same direction, the page signal becomes "high" for a time T, and an 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 further after a time T4 has elapsed.

Incidentally, after the time T1 has elapsed since the start of conveyance of the recording medium 1, the feeding motor 23 is driven for a time T to convey 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 image formed on the recording medium 1 in the developing means 5, and is conveyed by the drive of the conveying motor 24 while being in close contact with the recording medium 1.

When the recording medium 1 is conveyed, the recording paper 8 is conveyed so as to overlap the image forming area thereof, and when both are conveyed between the driving roller 5a and the driven roller 5b, both the recording medium 1 and the recording paper 8 are A predetermined pressure is applied by rollers 5a and 5b.

By applying the pressure, the image forming element of the recording film becomes
As shown in FIG. 1O, it is destroyed depending on the hardness state. When the image forming element is destroyed, the core inside the capsule flows out, and the color forming agent that flows out reacts with the color developer 8a of the recording paper 8 to form a color and is recorded as a visible image.

After the visible image is recorded on the recording paper 8 by the developing means 5 as described above, the recording medium 1 and the recording paper 8 are separated by the peeling roller 6, and the recording medium 1 is wound around the winding roll 7, and the recording medium 1 is Paper 8 is discharged onto discharge tray 9c.

As described above, the recording medium 1 and the recording paper 8 are stably conveyed, and high-quality color recording is performed in one shot.

Next, jam processing for the recording medium 1 will be explained.

If the recording medium 1 jams, release the latch between the first casing M and the second casing M2, and rotate the first casing M by about 100 degrees in the direction of arrow e as shown in FIG. Open. Guide rollers 3a and 3c that guide the recording medium 1 at this time
, 3d, guide plate 3b, etc. are provided in the first housing Ml, so that the transport path of the recording medium 1 is largely opened. Furthermore, at this time, the driving roller 5a and the driven roller 5 of the developing means 5
b are greatly separated from each other, and the pressed state of both rollers 5a and 5b is also released. Therefore, since the recording medium 1 is exposed, jam removal can be facilitated.

Since the recording medium 1 is exposed during this jam removal, it is possible that the image forming element reacts to external light. However, in this embodiment, when the first housing Ml is closed after the jam removal, , the reset switch 15 detects this, and upon receiving the detection signal, the control unit 20 turns on the transport motor.
A signal is sent to drive the transport motor 24 by a certain amount.

The drive amount of the transport motor 24 is the amount to transport the length of the recording medium 1 that may be exposed to external light when the first housing M1 is opened, and is the length shown in FIG. ,
This is the amount necessary to transport.

The control procedure for the jam processing is shown in a flowchart as follows:
As shown in FIG. 14, it is detected in step S1 whether or not the start button has been pressed, and if it has been pressed, the above-mentioned recording is performed in step S2, but if it has not been pressed, the process moves to step S3. Turn on the reset switch 15,
Detects OFF.

When the switch 15 is ON, that is, the first case M
When l is in the closed state, the process returns to step S1. On the other hand, when the switch 15 is OFF, that is, when the first casing Ml is opened due to jam processing, etc., the process moves to step S4, and the reset switch 15 is turned ON, that is, after the jam processing etc. are finished, the first casing Ml is opened. It is detected that the body Ml is closed. Then, when the switch 15 is turned on, steps 35 to S
At step 7, the transport motor ON signal is sent, and the recording medium 1
The unexposed recording medium 1 is conveyed to the recording means 4.

As described above, by conveying the recording medium l by a predetermined amount after the jam is cleared, a high-quality image without image disturbance caused by external light is recorded.
