Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image recording apparatus that superposes a photosensitive material and an image-receiving material and transfers an image to the image-receiving material.

[Prior art] After cutting a photosensitive material and an image-receiving material into predetermined lengths, an image is exposed on the photosensitive material and transported, and the image-receiving material is transported in correspondence with the transport of the photosensitive material, and both materials are overlapped. Image recording apparatuses that transfer images onto image-receiving materials are also known.

In this type of image recording apparatus, the photosensitive material and the image-receiving material are wound up into rolls and housed in different magazines, and are individually drawn out and cut into predetermined lengths. The cut photosensitive material is conveyed to an exposure section, where an image of the document is exposed, and after being coated with water as an image forming solvent, it is sent to an overlapping section.

On the other hand, the cut image-receiving material is conveyed in accordance with the conveyance of the photosensitive material and sent to the overlapping section.

The two materials sent to the overlapping section are brought into close contact with each other and overlaid so that the image is transferred to the image receiving material.

[Problems to be Solved by the Invention] Incidentally, in such a conventional image recording device, the photosensitive material and the image receiving material are individually drawn out from the magazine and cut, and furthermore, the photosensitive material and the image receiving material are fed into the overlapping section after exposure. Since the image-receiving material after cutting was only transported and sent to the overlapping section at the same time as the photosensitive material was transported, if the storage length of one of the materials in the magazine (remaining If the other material has already been pulled out of the magazine or cut when the length of the material (amount) is less than the predetermined length, the other material has to be discarded unused. especially,
If, after exposing an image on a photosensitive material, the length of the image-receiving material stored in the magazine (remaining amount) is less than a predetermined length, the exposure process itself becomes wasteful.

Furthermore, if one of the photosensitive materials and image-receiving materials becomes clogged (so-called jam) during transportation, the other material must be discarded, which also results in waste. Ta.

In consideration of the above facts, the present invention has been developed in the event that at least one of the photosensitive material and the image-receiving material (remaining length stored in the magazine) is less than a predetermined length, or if the material becomes clogged during transportation ( It is an object of the present invention to provide an image recording device that can effectively utilize the other material without discarding it even if a so-called jam occurs.

[Means for Solving the Problems] The image recording device according to the present invention independently pulls out a photosensitive material and an image-receiving material stored in different magazines, cuts them into a predetermined length, and then exposes an image to the photosensitive material. This is an image recording device that transports the image-receiving material in correspondence with the transport of the photosensitive material, overlaps both materials, and transfers an image to the image-receiving material. A photosensitive material remaining amount detection means for detecting the remaining amount of image receiving material, an image receiving material remaining amount detection means for detecting the remaining amount of image receiving material stored in the magazine, and a jam detection means for detecting a jam during the conveyance of the photosensitive material and image receiving material. means for moving the other material into position when it is detected that the length of the at least one material stored in the magazine is less than a predetermined length and/or when a jam is detected during delivery; The apparatus is characterized by comprising a control means for making the apparatus standby.

[Function] In the image recording apparatus configured as described above, the photosensitive material and the image-receiving material *4 are each independently pulled out from the magazine, cut into predetermined lengths, and then conveyed and overlapped to transfer the image onto the image-receiving material.

Here, the remaining amount of the photosensitive material is detected by the photosensitive material remaining amount detection means, and the remaining amount of the image receiving material is detected by the image receiving material remaining amount detection means. If at least one of the detected remaining amounts is less than the predetermined length, the control means causes the other material to wait at a predetermined position. Therefore, after the remaining amount is secured again, the material in the standby state can be used as it is and will not be wasted.

On the other hand, the jam detection means detects a jam during the conveyance of the photosensitive material and the image-receiving material.

Here, even if clogging of at least one material is detected, the other material is kept on standby at a predetermined position by the control means. Therefore, after the clogging is cleared, the material in the standby state can be used as it is, and in this case too, it is not wasted.

A thermal development transfer section 38 is disposed on the side of the water coating section 36, into which the water-coated photosensitive material 16 is fed.

On the other hand, a receiving material magazine 46 is arranged on the machine base 12 on the opposite side of the photosensitive material magazine 14, and an image receiving material 48 is wound up into a roll and stored therein. The widthwise dimension of the image-receiving material 48 is smaller than that of the photosensitive material 16, and a dye fixing material containing a mordant is coated on the image forming surface. An end mark 48A is also provided on the back surface of this image receiving material 48 at a position a predetermined length from the rear end.

As shown in detail in FIG. 3, an end mark 48A is attached to the image receiving material 48 near the drawer opening of the receiving material magazine 46.
A reflective optical sensor 118 is arranged to detect the
The end of the image receiving material 48 can be detected.

This reflective optical sensor 118 is also connected to the control device 112.

Downstream of the reflective optical sensor 118, a conveying roller 49,
A cutter 50 and conveyance rollers 51 and 53 are arranged.

The conveying roller 49, cutter 50, and conveying rollers 51, 53 are connected to the control device 112, and the image receiving material 48 is pulled out from the receiving magazine 46 by the conveying roller 49 and cut into lengths shorter than the photosensitive material 16 by the cutter 50. After that, it is conveyed to the thermal development transfer section 38 by conveyance rollers 51 and 53.

A standby sensor 120 is disposed downstream of the conveyance roller 53 (between the thermal development transfer section 38) and can detect the image receiving material 48 that has reached the conveyance roller 53. This standby sensor 120 is also connected to the control device 112.

The heat development transfer section 38 includes a heating drum 40 and an endless pressure belt 4.
Further, a superposing roller 55 is disposed in contact with the outer periphery of the heating drum 40.

The overlapping roller 55 overlaps the water-applied photosensitive material 16 conveyed by the squeeze roller 37 and the image receiving material 48 conveyed by the conveyance roller 53, and supplies the superposed material between the heating drum 40 and the endless pressure belt 42. It is supposed to be done.

In this case, the image-receiving material 48 is fed to the overlapping roller 55 at the same timing as the photosensitive material 16 is conveyed, so that the photosensitive material 16 is fed in a predetermined length in advance and is overlaid. There is. Furthermore, since the image-receiving material 48 is smaller than the photosensitive material 16 in both the width direction and the longitudinal direction, the photosensitive material 16
The peripheral portions of the image receiving material 48 are overlapped with each other with all four sides protruding from the peripheral portion of the image receiving material 48 .

The surface of the heating drum 40 is coated with Teflon 45, and a halogen lamp 44 is placed inside to heat the outer peripheral surface to about 90°C.

Furthermore, the endless pressure welding belt 42 is made of aromatic polyamide fiber (for example, Kevlar or Nomex; both are du
A heat-resistant material such as Pont Co., Ltd. (registered trademark) was coated with carbon-containing silicone rubber. structure and has electrical conductivity.

The photosensitive material 16 superimposed on the image receiving material 48 is transferred to the heating drum 40 and the endless pressure belt 4 in the superimposed state.
2, the heating drum 40 is sandwiched and conveyed over approximately 2/3 of the circumference of the heating drum 40.

When the photosensitive material 16 is heated during this nipping and conveying,
A mobile dye is released and at the same time this dye is transferred to the image receiving material 48.
The image is then transferred to the dye fixing layer.

In this case, since the endless pressure contact belt 42 is electrically conductive, generation of static electricity due to friction between the heating drum 40 and the endless pressure contact belt 42 or the photosensitive material 16 or the image receiving material 48 is prevented.

A bending guide roller 52 is disposed below the heating drum 40 on the downstream side of the endless pressure belt 42 in the material supply direction.
Further, a peeling claw 58 is rotatably supported at the lower part of the heating drum 40 on the downstream side of the bending guide roller 52 in the material supply direction. Further, a moving roller 80 is arranged near the peeling claw 58.

The tip of the peeling claw 58 is usually in contact with the outer periphery of the heating drum 40, and the peeling claw 58 is used to remove the photosensitive material 16 and the image-receiving material 48 that are sandwiched and conveyed between the endless pressure belt 42 and the heating drum 40. It engages only the leading end of the photosensitive material 16 stacked one above the other by a predetermined length, and peels this leading end from the outer periphery of the heating drum 40. Further, the peeled photosensitive material 16 is wrapped around a bending guide roller 52 and bent and guided downward, and then moved to a moving roller 80.
The photosensitive material (16) moves between it and the bending guide roller 52.
The image receiving material 48 is separated from the image receiving material 48 and conveyed. These peeling claws 58 and moving rollers 80 are also connected to the control device 112.

A waste photosensitive material storage box 98 is arranged below the heating drum 40, into which the separated photosensitive material 16 is fed.

On the other hand, a peeling claw 100 and a peeling claw 102 are arranged near the heating drum 40 on both sides of the peeling claw 58, and separate the image receiving material 48, which is separated from the photosensitive material 16 and moves together with the heating drum 40, into the heating drum. It is designed to be peeled off from the outer periphery of 40. The image receiving material 48 peeled off from the outer periphery of the heating drum 40 is collected on a tray 104.

A display section 122 is arranged at the top of the machine stand 12, and displays the end of the photosensitive material 16 and the image receiving material 48, and the end of the photosensitive material 16 and image receiving material 48.
It is now possible to display. This display section 122 is also connected to the control device 112.

Next, the control routine of this embodiment will be explained.

When the image recording process is started, a photosensitive material conveyance process is performed in step 200 as shown in FIG. 6th
The figure shows this photosensitive material transport processing routine.

In step 206, the transport rollers 17, 19 are started to be driven, and the photosensitive material 1116 is pulled out from the photosensitive material magazine 14. Next, in step 208, it is determined whether the end of the photosensitive material 16 has been detected based on the detection signal of the reflective optical sensor 110, and further, in step 210
At step 2, it is determined whether or not the drawing has been carried out for a predetermined length based on the number of clock pulses from the start of drawing.

If it is determined in step 210 that the predetermined length has been pulled out, the driving of the conveyance roller 17 is stopped in step 212, and further, in step 214, the cutter 18 is pulled out.
is activated and disconnected.

After cutting, the process advances to step 216, where the photosensitive material 16 is transported to the exposure section 20, the exposure device 22 is activated, and the photosensitive material 16 is transferred to the mounting plate 30.
The image of the original document 32 placed thereon is scanned and exposed onto the photosensitive material 16 located in the exposure section 20 . Photosensitive material 16 after exposure
is reversed by a reversing roller 34 and conveyed to a water application section 36.

Next, in step 218, the water application sensor 114 determines whether the photosensitive material 16 has reached the population of the water application section 36, and if it has reached the population of the water application section 36, the conveyance is stopped in step 220 and the photosensitive material 16 is placed in a standby state. At the same time, flag F is set in step 222, and image-receiving material conveyance processing (step 202 in FIG. 5) is performed.

On the other hand, if the end of the photosensitive material It l 6 is detected in step 208, the process advances to step 224, where the driving of the conveying rollers 17 and 19 is stopped and the photosensitive material magazine 14 is stopped.
The drawing of the photosensitive material 16 from the holder is stopped. Furthermore, in step 226, the photosensitive material 16 less than the predetermined length is
At the same time, the end of the photosensitive material 16 is displayed on the display section 122, and the process immediately proceeds to the image-receiving material conveyance process (step 202 in FIG. 5).

FIG. 7 shows an image-receiving material transport processing routine.

In step 228, the transport rollers 49, 51 are started to be driven, and the image receiving material 48 is pulled out from the receiving material magazine 46. Next, in step 230, it is determined whether the end of the image receiving material 48 is detected based on the detection signal of the reflective optical sensor 118, and further, in step 232, the image receiving material 48 is drawn out for a predetermined length based on the number of clock pulses from the start of drawing. judge whether it is true or not.

If it is determined in step 232 that the predetermined length has been pulled out, the driving of the conveyance roller 49 is stopped in step 234, and further, in step 236, the cutter 50 is pulled out.
is activated and disconnected.

After cutting, the process proceeds to step 238, where the first general feed roller 51.
53 is driven to convey the cut image-receiving material 48.

Next, in step 240, the standby sensor 120 determines whether or not the image receiving material 48 has reached the conveyance roller 53. If it has reached the conveyance roller 53, the conveyance is stopped in step 242 to enter a standby state, and a flag is set in step 244. G is set, and the transfer process (step 204 in FIG. 5) is performed.

On the other hand, if the end of the image-receiving material 48 is detected in step 230, the process proceeds to step 246, where the driving of the conveying rollers 49, 51 is stopped and the drawing of the image-receiving material 48 from the receiving material magazine 46 is stopped. Further step 2
At step 48, the image receiving material 48 that is less than a predetermined length is disposed of, and the image receiving material 48 is displayed on the display section 122.
An end message is displayed, and the process immediately proceeds to the transfer process (step 204 in FIG. 5).

FIG. 8 shows a transfer processing routine.

In this transfer process, it is determined in step 250 whether the flag F is set (that is, whether the photosensitive material 16 has been cut into a predetermined length, transported, and is in a standby state in the water application section 36). If it has been set, the process advances to step 252 to check whether the flag G is set (that is, whether the image receiving material 48 has been cut to a predetermined length, transported, and is on standby at the transport roller 53). If it is set, step 25
Proceed to step 4.

In step 254, the conveyance of the photosensitive material 16 that has been on standby in the water application section 36 is resumed, and
After water is applied as an imaging solvent by
The image is conveyed to the overlapping roller 55 of the thermal development transfer section 38 .

On the other hand, the image-receiving material 48 that has been in a standby state on the transport roller 53 is restarted when the photosensitive material 16 coated with water is detected by the mount timing sensor 116 (
In other words, the photosensitive material 16 is conveyed at the same timing as the conveyance of the photosensitive material 16), and the photosensitive material 16 is sent to the overlapping roller 55 with a predetermined length in advance and is overlaid.

In this case, since the image-receiving material 48 is smaller in width and length than the photosensitive material 16, the image-receiving material 48 is smaller on all four sides of the photosensitive material 16.
The image-receiving material 48 is superimposed with the photosensitive material 16 leading by a predetermined length, that is, from a position a predetermined length from the tip of the photosensitive material 16, particularly at the tip.

Thermal development (In the image transfer section 38, the photosensitive material 16 and the image receiving material 48 are supplied between the heating drum 40 and the endless pressure belt 42, and are held in an overlapping state while being pressed against the outer periphery of the heating drum 40. transported.

When the photosensitive material 16 is pressed in the thermal development transfer section 38 (between the heating drum 40 and the endless pressure belt 42) with the image receiving material 48 superimposed, it releases a mobile dye, and this dye The image is transferred to the dye fixing layer of the image receiving material 48 to obtain an image.

In this case, the photosensitive material 16 and the image receiving material 48 are reliably overlapped, and the peripheral portion of the photosensitive material 16 is
Since the material protrudes from the periphery of the heating drum 8 and is in close contact with the outer periphery of the heating drum 40, a predetermined pressure can be applied without each material shifting during conveyance, and a high-quality image can be obtained.

Furthermore, since the endless pressure welding belt 42 has conductivity,
Generation of static electricity due to friction between the heating drum 40 and the endless pressure belt 42 or the photosensitive material 16 or the image receiving material 48 is prevented, and the image obtained on the image receiving material 48 is prevented from fogging.

When the photosensitive material 16 and the image-receiving material 48 are sandwiched and conveyed and reach the lower part of the heating drum 40, in step 256, a peeling claw 58 is attached to the tip of the photosensitive material 16, which is conveyed a predetermined length ahead of the image-receiving material 48. When engaged, the leading end of the photosensitive material 16 is peeled off from the outer periphery of the heating drum 40.

Further, the peeled photosensitive material 16 is moved to a bending guide roller 52.
The moving roller 80 further moves and the photosensitive material 1 is wrapped around the bending guide roller 52 and guided downward.
6 is held therebetween and is separated from the image-receiving material 48 and conveyed.

The separated photosensitive material 16 is sent to a waste photosensitive material storage box 98. On the other hand, the image receiving material 48 that is separated from the photosensitive material 016 and moves together with the heating drum 40 is moved by the peeling roller 100.
Then, it is peeled off from the outer periphery of the heating drum 40 by the peeling claw 102 and accumulated on the tray 104.

Next, in step 258, the flag FSG is reset and the process ends.

Further, if the flag FSG is not set in step 250 or step 252, that is, if at least one of the materials is at the end, the process is immediately terminated.

Next, processing for clogging (so-called jam) during conveyance of the photosensitive material 416 and the image receiving material 48 will be explained.

FIG. 9 shows a jam processing interrupt routine.

In step 260, it is determined whether the reflective optical sensor 110 of the photosensitive material 16, the interleaving paper timing sensor 116, the reflective optical sensor 118 of the image receiving material 480, and the standby sensor 120 have detected each within a predetermined time from the start of withdrawal, i.e. Determine if it's a jam. Next, in step 262, it is determined whether the photosensitive material 16 is jammed, and if the image receiving material 48 is jammed, step 28 is performed.
Go to 0.

If the photosensitive material 16 is jammed, a message indicating that the photosensitive material 16 is jammed is displayed on the display section 122 in step 264. Further, in step 266, it is determined whether the flag G is set (that is, whether the image receiving material 48 is cut into a predetermined length, transported, and is in a standby state on the transport rollers 53). If it is not in the standby state, the process proceeds to step 268, where it is determined whether the image receiving material 48 has been pulled out based on the signal from the reflective optical sensor 118, and if it has been pulled out, it is determined in step 270 whether or not it has been cut to a predetermined length. If it has not been cut, it is cut in step 272.

After cutting, the process proceeds to step 274, where the conveyance roller 51 is driven to convey the image receiving material 48, and then step 2
At 76, it is determined by the standby sensor 120 whether the image receiving material 48 has reached the conveyance roller 53, and the conveyance roller 5
When the number reaches 3, the conveyance is stopped in step 278 and a standby state is entered.

In step 266, the image receiving material 48 is transferred to the transport roller 53.
, and step 268
If the image-receiving material 48 has not been pulled out, the process ends immediately.

On the other hand, if it is determined in step 262 that the image-receiving material 48 is jammed, and the process proceeds to step 280, a message indicating that the image-receiving material 48 is jammed is displayed on the display section 122 in step 280. Furthermore, in step 282, whether or not the flag F is set (i.e., the photosensitive material 16
is cut into a predetermined length, transported, and is in a standby state at the water application section 36). If the photosensitive material 16 is not in the standby state, the process proceeds to step 284, where it is determined whether or not the photosensitive material 16 has been pulled out based on the signal from the reflective optical sensor 110. If it has been pulled out, it is determined in step 286 whether or not the photosensitive material 16 has been cut to a predetermined length. If it has not been cut, it is cut in step 288.

After cutting, the process proceeds to step 290, where the conveyance roller 19 is driven and the photosensitive material 16 is conveyed, and then step 2
At step 92, the water application sensor 114 determines whether the photosensitive material 16 has reached the population of the water application section 36, and when it reaches the entrance of the water application section 36, the conveyance is stopped at step 294 and the photosensitive material 16 enters a standby state.

In step 282, if the photosensitive material 16 is in a standby state in the water application section 36, and in step 28
If the photosensitive material 16 has not been drawn out in step 4, the process ends immediately.

In this way, if the remaining amount of at least one of the photosensitive material 16 and the image receiving material 48 is less than a predetermined length, the other material is kept waiting at a predetermined position, so the magazine is replaced and the remaining amount is ensured again. After the material has been prepared, the material in the standby state can be used as is and will not be wasted.

Furthermore, even if a blockage in at least one of the photosensitive material 16 and the image-receiving material 48 is detected, the other material is kept on standby at a predetermined position. Can be used as is,
In this case too, nothing is wasted.
