A bonding roller 120 is arranged on the outer periphery of the side.

The photosensitive material 16 is adhered between the bonding roller 120 and the squeeze roller 68 of the water application section 62 corresponding to the back surface (the opposite side to the image forming surface) of the photosensitive material 16 transported by the squeeze roller 68. A guide plate 122 for guiding to the aligning roller 120 is provided. Irregularities are formed on the surface of the guide plate 122 by embossing, and thereby the friction between the guide plate 122 and the photosensitive material 16 after water application is reduced.

On the other hand, between the bonding roller 120 and the transport roller 114, a blade guide 124 for guiding the image receiving material 108 transported by the transport roller 114 to the bonding roller 120 is arranged. The surface of the blade guide 124 is subjected to Teflon (trade name) processing (or a Teflon tee is attached), so that the surface of the blade guide 124 slides well with the image receiving material 108 and is prevented from being damaged.

The bonding roller 120 has an outer diameter of approximately 2 at the center in the axial direction.
It is composed of a so-called crown roller of 9 mm, and its outer peripheral surface is covered with silicon rubber. The bonding roller 120 is pressed against the outer periphery of the heating drum 116 by applying a pressure of approximately 15 kgf at both ends.

Endless pressure contact belt 118 pressed against the outer periphery of heating drum 116
Is formed by covering a woven fabric material with rubber. The woven fabric material is sewn with heat-resistant fibers such as aromatic polyamide fibers (for example, Kevlar or Nomex: both are registered trademarks of DuPont), and monofilament fibers are used in the belt width direction. The rigidity in the belt width direction has been improved. The coating rubber is made of silicon rubber containing carbon and has conductivity.

The endless pressure contact belt 118 has four winding rollers 13.
4, 136, 138, 140
The portion between the eight winding rollers 134 and 140 is pressed against the outer circumference of the heating drum 116.

The winding rollers 134, 136, and 138 are made of aluminum, and have flange portions at both ends in the axial direction for preventing the belt from shifting. At both ends in the longitudinal direction of the winding roller 136, a pressing force of 2.5 kgf (a practical range is 0.5 to 3.0 kgf) is applied in a direction away from the heating drum 116, whereby the endless pressure contact belt 118 is A predetermined tension is applied.

On the other hand, the wrapping roller 140 is formed of a rubber roller, and a motor (not shown) as a drive source is connected to a rotating shaft thereof. For this reason, the winding roller 140
When the is rotated by the motor, the endless pressure contact belt 118 wound around the winding roller 140 is rotated, and accordingly, the heating drum 116 is driven by the frictional force between the endless pressure contact belt 118 and the heating drum 116. Is rotated. When the heating drum 116 rotates, the bonding roller 120 disposed in pressure contact with the outer periphery of the heating drum 116 also rotates together by frictional force.

Further, in this case, the heating drum 116 and the bonding roller 1
The speed at which the photosensitive material 16 or the image receiving material 108 is conveyed by the squeeze roller 68 or the conveying roller 114 is higher than the speed at which the photosensitive material 16 and the image receiving material 108 are nipped and conveyed by 20 (in other words, the rotational speed of the outer peripheral surface of the heating drum 116). Is set to be about 2% slower, whereby the photosensitive material 16 and the image receiving material 108 are subjected to a backlash when they are fed to the bonding roller 120. A one-way clutch (not shown) is attached to the drive shafts of the squeeze roller 68 and the transport roller 114, so that a predetermined tension is maintained.

The leading end of the image receiving material 108 is conveyed between the heating drum 116 and the bonding roller 120 in synchronization with the conveyance of the photosensitive material 16, and the photosensitive material 16 has a predetermined length (in this embodiment, approximately
20 mm) The sheet is fed between the laminating roller 120 and the heating drum 116 in the preceding state and is superposed.

The photosensitive material 16 and the image receiving material 108 superimposed by the laminating roller 120 are heated while the superposed state is maintained between the heating drum 116 and the endless pressure contact belt 118.
6 1/2 rotation (winding roller 134 and winding roller 140
). When the photosensitive material 16 is heated during this nipping and conveying, it releases a movable dye,
At the same time, the dye is transferred to the dye fixing layer of the image receiving material 108 to obtain an image.

A bending guide roller 142 and a peeling claw 154 are disposed below the heating drum 116 on the downstream side of the endless pressure contact belt 118 in the material supply direction. The peeling claw 154 is related to only the front end portion of the photosensitive material 16 that has been overlapped with a predetermined length ahead of the photosensitive material 16 and the image receiving material 108 that are nipped and conveyed between the endless pressure contact belt 118 and the heating drum 116. The leading end is peeled off from the outer periphery of the heating drum 116, and the bending guide roller 1
42 guides the peeled photosensitive material 16 around.

Below the peeling claw 154, a cutter 18 for cutting the photosensitive material 16 is provided.
0, a waste photosensitive material passage sensor 181 and a waste photosensitive material storage box 178 are disposed, and the photosensitive material 16 separated from the outer periphery of the heating drum 116 and separated from the image receiving material 108 is finely cut by a cutter to be a waste photosensitive material storage box. Integrated in 178.

A drying fan 182 for blowing air to dry the image receiving material 108 is arranged on a side of the peeling claw 154.

In the vicinity of the heating drum 116 above the peeling claw 154, a peeling roller
An image receiving material 108 that is separated from the photosensitive material 16 and moves with the heating drum 116 is peeled off from the outer periphery of the heating drum 116. The peeled image receiving material 108 is accumulated on the tray 184.

Next, the operation of the image recording apparatus will be described. Photosensitive material pulled out from photosensitive magazine 14 by nip roller 18
After being cut into a predetermined length by the cutter 20, the 16 passes through the exposure unit 22 and is conveyed in the direction of the flapper 36. The flapper guides the photosensitive material 16 to a transport path located above the flapper. The guided photosensitive material 16 is reversed at the reversing section 34 and is conveyed to the exposure section 22. When the photosensitive material 16 is nipped by the transport roller 26, the drive of the transport roller 26 is temporarily stopped, and the photosensitive material 16 enters a standby state immediately before the exposure unit 22.

On the other hand, while the photosensitive material 16 is being conveyed, the original 54 is pressed. That is, first, while the light source 40 moves, the reflection mirror 46 enters the optical path, and the image density of the image of the original 54 (in other words, the image of the original 54 is a print original or a photo original). Is measured, and the color adjustment filter and the aperture slit plate 52 are adjusted based on the measured values.

Next, the reflecting mirror 46 is separated from the optical path, and the light source 40, the moving mirrors 42A and 42B and the lens unit are removed.
48 is returned to the home position (image scanning start position).

Here, the driving of the transport rollers 24 and 26 is started again, and the photosensitive material 16 passes through the exposure unit 22 at a speed of approximately 100 mm / sec. At the same time when the photosensitive material 16 passes through the exposure section 22, the light source 40, the moving mirrors 42A and 42B and the lens unit
48 is moved along the light source device plate 50, and the photosensitive material 16 is scanned and exposed. In this case, since the exposure unit 22 is forcibly cooled by the cooling fan 58, exposure failure due to a temperature rise does not occur.

When the exposure is started, that is, when the driving of the transport rollers 24 and 26 is restarted, the flapper 37 is switched upward, whereby the exposed photosensitive material 16 is transported to the reversing unit 60. Photosensitive material
16 is sent to the water application unit 62 after being inverted by the inversion unit 60.

In the water application section 62, water as an image forming solvent is applied to the photosensitive material 16, and excess water is removed by a squeeze roller 68. The photosensitive material 16 to which water as an image forming solvent has been applied in the water application section 62 is sent to the thermal development transfer section 104 by the squeeze roller 68.

On the other hand, the image receiving material 108 is also pulled out from the material receiving magazine 106 by the nip roller 110, and further cut by the cutter 112 to a length shorter than the photosensitive material 16, and then the conveying roller
It is conveyed by 114 and sent to the thermal development transfer unit 104. Further, after the cutting, the nip by the nip roller 110 is released, and deformation caused by nip of the leading end (image forming surface) of the image receiving material 108 for a long time is prevented.

Here, the image receiving material 108 is conveyed to the thermal development transfer unit 104 at the same time as the conveyance of the photosensitive material 16, and
Is fed between the laminating roller 120 and the heating drum 116 in a state of preceding by a predetermined length (approximately 20 mm in the present embodiment) and is superposed.

In this case, a guide plate 70 is arranged between the bonding roller 120 and the squeeze roller 68 of the water application section 62, and the photosensitive material 16 sent from the squeeze roller 68 is reliably guided to the bonding roller 120. You. Further, a blade guide 124 is disposed between the bonding roller 120 and the transport roller 114 of the image receiving material 108, and the image receiving material 108 is also guided to the bonding roller 120 without fail.

The leading end of the photosensitive material 16 guided to the bonding roller 120 prior to the image receiving material 108 is
After being sandwiched by the heating drum 116 and the heating drum 116, the squeeze roller 68 increases the nipping and conveying speed of the photosensitive material 16 by the heating drum 116 and the bonding roller 120 (in other words, the rotational movement speed of the outer peripheral surface of the heating drum 116). Since the conveying speed of the photosensitive material 16 is set to be slowed down by about 2%, the photosensitive material 16 is not affected by the back tension and is not slackened.

Next, the image receiving material 1 guided to the bonding roller 120
When the leading end of 08 reaches the pressure contact point between the laminating roller 120 and the heating drum 116, the photosensitive material 16 is sequentially superimposed.
In this case as well, the conveying roller 114 is nipped against the nipping and conveying speed of the image receiving material 108 by the heating drum 116 and the bonding roller 120.
, The conveying speed of the image receiving material 108 is set to be slow, so that the image receiving material 108 is not subjected to backlash and slack does not occur. Therefore, the photosensitive material 16 and the image receiving material
108 is superimposed uniformly without wrinkles.

Also, the photosensitive material is provided by a one-way clutch mounted on the drive shaft of the squeeze roller 68 and the transport roller 114.
Since the tension acting on the photosensitive material 16 and the image receiving material 108 is maintained at a predetermined value, the photosensitive material 16 and the image receiving material 108 are not damaged or cannot be transported due to excessive tension.

Further, in this case, since the width of the image receiving material 108 and the length thereof in the longitudinal direction are smaller than those of the photosensitive material 16, the peripheral portion of the photosensitive material 16 has four sides.
It is superimposed in a state protruding from the periphery of 108.

The photosensitive material 16 and the image receiving material 108, which are superimposed by the bonded roller 120, are heated while the superposed state remains between the heating drum 116 and the endless pressure contact belt 118.
About 1/2 lap of 116 (wrapping roller 134 and winding roller 1
40). When the photosensitive material 16 is heated during the nipping and conveying, the movable dye is released, and at the same time, the dye is transferred to the dye fixing layer of the image receiving material 108 to obtain an image.

In this case, the photosensitive material 16 and the image receiving material 108 are uniformly overlapped without wrinkling.
The four sides protrude from the periphery of the image receiving material 108 on all four sides and are in close contact with the outer periphery of the heating drum 116, so that a predetermined pressure can be applied without shifting each material during the conveyance, and there is no image unevenness. Good quality images can be obtained.

Further, since the endless pressure contact belt 118 is directly and forcibly rotated by the winding roller 140 connected to the motor, the bending ratio of the winding portion is large, and even if the belt is bent at a plurality of locations, it can be reliably determined. Rotate at the speed of. Further, since the endless pressure contact belt 118 of the heating drum 116 has a small resistance to the rotational driving force and is in pressure contact with the heating drum 116 over a wide range, the rotational force from the endless pressure contact belt 118 is reliably transmitted by friction (one of the rotational force). Part is transmitted without loss). Therefore, there is no difference in rotation speed between the endless pressure contact belt 118 and the heating drum 116. Therefore, a shear force is not generated between the photosensitive material 16 and the image receiving material 108 which are nipped and conveyed by the endless pressure contact belt 118 and the heating drum 116, so that the two materials are not displaced from each other. An image is obtained.

Further, since the endless pressure contact belt 118 has conductivity, generation of static electricity due to friction between the heating drum 116 and the endless pressure contact belt 118 or the photosensitive material 16 or the image receiving material 108 is prevented, and an image obtained on the image receiving material 108 is obtained. No fogging occurs.

Thereafter, when the photosensitive material 16 and the image receiving material 108 are nipped and conveyed and reach the lower portion of the heating drum 116, a peeling claw is attached to the leading end of the photosensitive material 16 which is conveyed a predetermined length ahead of the image receiving material 108.
154 are engaged, and the tip of the photosensitive material 16 is peeled off from the outer periphery of the heating drum 116. Further, the peeled photosensitive material 16 is
It is wound around the bending guide roller 142 and bent downward,
It is cut into small pieces by the cutter 180 and collected in the waste photosensitive material storage box 178.

On the other hand, the image receiving material 108 that is separated from the photosensitive material 16 and moves while being in close contact with the heating drum 116 is a drying fan 182.
While being dried by the heating drum 116, it moves between the heating drum 116 and the peeling claw 176 separated from the outer periphery thereof and is sent to the peeling roller 174. Here, the heating roller 116 is peeled off from the outer periphery of the heating drum 116 by the peeling roller 174 and the peeling claw 176, and is accumulated on the tray 184.

And the tip detection sensor 23 is connected to the microcomputer 190. The micro computer 190 is connected to the motor 17 and the cutter 20 via a driver (not shown).

Since the image receiving material side has the same configuration, the illustration is omitted.

Next, a control routine of the control system will be described. Since the same applies to the image receiving material side, in the following control routine, only the control routine for the photosensitive material side will be described.

FIG. 6 shows a part of a main routine which is started when the copy start switch of the image recording apparatus is turned on. When the start switch is turned on,
When the motor 17 is rotated in 200, the photosensitive material is transported in the forward direction, that is, the direction in which the photosensitive material is pulled out from the photosensitive material magazine case 15. When the conveyance is started, a pulse is output from the rotary encoder 19. Next Step 202
Then, it is determined whether or not the leading edge detection sensor 23 has detected the leading edge of the photosensitive material, and when it is determined that the leading edge has been detected,
In step 204, the leading edge detection flag F is set, and in step 206, the value of the size pulse PA is set to the number of pulses Po corresponding to the length of the copy size set by the copy size setting switch in the photosensitive material transport direction.
Set up.

FIG. 7 shows an interrupt routine interrupted by the rise of a pulse output from the rotary encoder. In step 210, the pulse number P is incremented. In the next step 214, it is determined whether or not the leading edge detection flag F is set. When the flag F has been reset, the routine returns to the main routine, and when the flag F has been set, step 216 is executed.
It is determined whether or not the number of pulses P has become equal to or larger than the size pulse PA. When P <PA, the process returns to the main routine. When P ≧ PA, the conveyance of the photosensitive material is stopped at step 218, and a cut signal is output at step 220 to cut the photosensitive material by the cutter 20. At step 222, the pulse number P is reset, and at step 224, the leading end detection flag F is reset.

FIG. 1A shows an interruption routine interrupted by the occurrence of a jam between the discharge port of the photosensitive material magazine case 15 and the cutter 20. After the photosensitive material is started to be conveyed by the motor 17 in the forward direction. This interruption occurs when the leading end of the photosensitive material does not reach the leading end detection sensor 23 within a predetermined time.

In step 230, the jam flag J is set, and in step 232, the jam flag J is stored in the backup RAM 192. FIG. 1 (B) shows a case where the photosensitive material magazine case 15 is pulled out from the machine base 12 and then the photosensitive material magazine case 15 is reattached to the machine base 12 when the DC5V signal input to the microcomputer 190 rises (case). This indicates an interrupt routine interrupted by the detachment information. In step 234, the jam flag J is reset.

Therefore, during jamming, the operator always pulls out the photosensitive material magazine case 15 according to the above-mentioned direction, and the presence or absence of jammed paper from the discharge port of the photosensitive material magazine case 15 to the cutter 20 is confirmed. It is possible to prevent the user from forgetting to remove the jam paper from the discharge port 15 to the cutter 20.

FIG. 8 shows an interrupt routine interrupted by the rise of a pulse output from the rotary encoder.
It is determined whether at least one of B and 101C has been turned off. That is, the front door 10A or the front door 1 of the image recording apparatus
When it is determined that at least one of the microswitches 101A, 101B, and 101C has been turned off, for example, when the photosensitive material magazine 14 or the receiving material magazine 106 is opened, the upper part 10C is opened, and the jam processing is performed, step 236 is performed.
Sets the front end processing flag G and returns to the backup RA
Remember in M.

FIG. 9 shows a part of an initial routine which is started by interruption when the jam processing and the replenishment of the photosensitive material are completed, the front doors 10A and 10B and the upper part 10C of the image recording apparatus are closed, and the power is turned on. Perform a jam check in step 237. In the case of a jam, jam processing is performed. In the case of no jam, it is determined in step 238 whether or not the leading edge processing flag G is set. If it is determined that the leading edge processing flag G is set,
In step 239, the tip processing is performed. That is, the photosensitive material 16 is pulled out by a predetermined amount, for example, a distance (reference L in FIG. 5) from the photosensitive material magazine case 15 to the cutter 20, cut, and discharged to the waste photosensitive material storage box 178.

FIG. 10 shows an interrupt routine started by an interrupt when the cutter 20 is operated during the tip processing in step 254. In step 260, the tip processing flag G is reset. Therefore, if the tip processing is interrupted after the photosensitive material 16 has been cut to the predetermined length, the tip processing flag G stored in the backup RAM 192 is cleared. Therefore, when the power is turned on again, the tip of the photosensitive material 16 is not cut again, and the photosensitive material 16 is not wasted. Further, since the backup RAM 192 is backed up by the rechargeable battery 194, if the power of the image recording apparatus 10 is cut off before the photosensitive material 16 is cut to a predetermined length, the front end processing flag G is stored in the backup RAM 192. When the power is turned on again when the power is turned on, the front end processing is performed and the front end of the photosensitive material 16 is always cut off.

In the above description, the leading edge processing of the photosensitive material has been described, but the invention can be similarly applied to the leading edge processing of the image receiving material.
Although the image recording apparatus using the heat source image transfer has been described above, the present invention can be applied to a device using an image recording material wound in a roll shape, such as a facsimile.
