Description

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to an image recording apparatus that overlaps a photosensitive material and an image-receiving material, transfers an image recorded on the photosensitive material to the image-receiving material, and obtains an image on the image-receiving material. .

[Prior Art] A heat-developable photosensitive material is used as the above-mentioned photosensitive material, and the photothermally-developable material on which the image has been exposed is superimposed on an image-receiving material and heated to be thermally developed, and the exposed image is transferred to the image-receiving material. Image recording devices that obtain images on image-receiving materials are known.

In this type of image recording apparatus, a separation means such as a separation arm is arranged near the heat development transfer section, and the heat development photosensitive material after heat development transfer is separated from the image receiving material by this separation arm. ing. Furthermore, the separated photothermographic material is conveyed by a conveyor belt and is collected in a waste box placed at the lowest end of the apparatus.

[Problems to be Solved by the Invention] By the way, a heat-developable photosensitive material curls when it is separated from an image-receiving material after heat development transfer due to reasons such as being wrapped around a roller and being conveyed or being heated.

In this regard, conventional image recording apparatuses have a structure in which the curls generated on the photosensitive material are simply collected in a waste box without being removed, so this curl increases the apparent volume of the heat-developable photosensitive material that accumulates, causing it to be discarded. There is a problem in that the actual amount of boxes that can be stacked is reduced.

The present invention has been developed in consideration of the above facts, and is capable of reliably transporting the photosensitive material separated from the image-receiving material after an image has been transferred without causing any clogging, and furthermore, allowing the photosensitive material to be accumulated in a small space without waste. The object is to obtain an image recording device that can realize this with a simple structure.

[Means for Solving the Problems] The image recording apparatus according to the present invention overlaps a photosensitive material and an image-receiving material, transfers an image recorded on the photosensitive material to the image-receiving material, and further separates the photosensitive material and the image-receiving material by a separating means. An image recording apparatus that obtains an image on an image-receiving material by separating the photosensitive material d, which is disposed on the downstream side of the photosensitive material conveying path of the separating means and is conveyed along the conveying direction while sandwiching the widthwise center portion of the conveyed photosensitive material d. a bending means for bending; and a protrusion mounting device disposed downstream of the photosensitive material conveyance path of the bending means and for accumulating the photosensitive material sent out from the bending means in a mountain shape with the bending portion as the apex. and a pressing member that presses and holds both sides of the folded portion of the photosensitive material accumulated on the waste tray.

[Function] In the image recording apparatus configured as described above, the photosensitive material after thermal development transfer is separated from the image-receiving material by the separating means. The separated photosensitive material is conveyed while being held by a bending means, and the center portion in the width direction is forcibly bent along the conveyance direction. moreover,
The folded photosensitive material is delivered from the folding means to a waste tray.

The photosensitive material sent to the waste tray is pressed and held by the pressing member on the protrusion placement section.

In this case, the photosensitive materials accumulated on the waste tray have their center portions in the width direction bent along the conveyance direction to increase bending rigidity, and the bent portions are furthermore Since both sides are pressed and held in a chevron-shaped state with the bent portion as the apex, they are regularly stacked and accumulated. Therefore, the apparent volume does not increase when stacked, and the space of the waste tray can be used effectively, making it possible to downsize.

Furthermore, since the stacked photosensitive material is pressed and held by the pressing member, curling does not occur again over time.

Furthermore, in this case, irregular undulations may occur in the photosensitive material upstream of the bending means due to bending, but if a conveyance roller is provided downstream of the separation means, the photosensitive material can be Since it is held between the conveyance rollers, the generated undulations will not be transmitted to the upstream side of the conveyance rollers, and will not adversely affect the conveyance of the photosensitive material and will not be clogged.

In the present invention, the photosensitive material may be any material as long as an image obtained by imagewise exposure can be transferred as a visible image onto an image-receiving material.

The photosensitive material 16 is pulled out from its outer periphery, cut into a predetermined length by a cutter 18, and then wound around the outer periphery of a rotating drum 20. An exposure head 22 is disposed corresponding to the outer periphery of the rotating drum 20, and rotates the rotating drum 20 in the direction of arrow A to expose an image onto the wound photosensitive material 16.

After exposure, the photosensitive material 16 is rotated in the reverse direction of the rotating drum 20.
After being peeled off from the rotating drum 20 by the scraper 24 and applied with water as an image forming solvent by the water application section 26,
The image is sent to the thermal development transfer section 28.

On the other hand, the uppermost layer of the plurality of image receiving materials 32 accommodated in the tray 30 is sent to the thermal development transfer section 28 .

The thermal development transfer section 28 includes a pair of transport rollers 3 that are in pressure contact with each other.
4.36.38 are arranged at equal intervals. A motor (not shown) is connected to these conveyor roller pairs 34, 36, 38, and a driving force is transmitted to the conveyor roller pair 34, 36, 38 to receive rotational force, and the photosensitive material 16 and the image-receiving material 32 are moved between the opposed conveyor roller pairs 34, 36, and 38. They are sandwiched and conveyed in a stacked state.

A heater 40 is arranged on the outer periphery of each conveyance roller. For this reason, the photosensitive material 16 and the image-receiving material 32, which are sandwiched and conveyed by each pair of conveying rollers, are heated and pressed together by heat transfer through the respective conveying rollers.

A separation section 42 is arranged downstream of the thermal development transfer section 28 . As shown in FIG.
and a plurality of tension rollers 53 are arranged.

An endless belt 54 is wound around the rollers 44 and 48, and an endless heald 56 is wound around the rollers 46, 50, and 52. A portion of the endless belt 56 between the rollers 46 and 50 comes into contact with a portion of the endless belt 54 between the rollers 44 and 48, forming an image-receiving material conveyance path 58.

A separation arm 60 serving as separation means is arranged near the roller 44 and the roller 46, and a separation arm 60 is arranged near the roller 44 and the roller 46.
The photosensitive material 16 and the image-receiving material 32 that are sent out from there are separated. Therefore, the image-receiving material 32 separated by the separation arm 60 is conveyed while being held between the endless belt 54 and the endless belt 56 (in the image-receiving material conveying path 58).

A heater 62 is disposed inside the endless belt 54 in correspondence with the image receiving material conveying path 58, and is designed to dry the image receiving material 32 being conveyed. The image-receiving material 32 after drying is transferred to a take-out tray 64 formed at the top of the machine stand 12.
It is meant to be sent upwards.

On the other hand, as shown in FIGS. 1 to 3, directly below the separation arm 60, a pair of conveyance rollers 66 are placed in contact with each other so as to nip and convey the photosensitive material 16 separated by the separation arm 60. It has become.

An arc-shaped guide plate 68 is arranged directly below the conveyance roller 66, and a stiff roller 70 as a bending means is arranged near the tip of the guide plate 68. Therefore, the photosensitive material 16 that is being nipped and conveyed by the conveying rollers 66 is guided by the guide plate 68 and sent to the stiffening rollers 70.

The buckled roller 70 is composed of a male roller 72 and a female roller 74, and is attached to a shaft 76, 78 at a position corresponding to the widthwise center of the photosensitive material 16 being fed.

The shafts 76 and 78 are connected to a drive source (not shown), so that the male roller 72 and the female roller 74 rotate under the driving force so as to nip and convey the photosensitive material 16.

The outer periphery of the acid roller 74 is knurled so that it can securely hold the photosensitive material 16.

As shown in FIG. 5, a protrusion 80 with a rectangular cross section is formed on the outer periphery of the male roller 72, and a recess 82 with a rectangular cross section is formed on the outer periphery of the acid roller 74.
They are configured to fit into each other. For this reason, the photosensitive material 1 being pinched and conveyed between the male roller 72 and the acid roller 74
At this time, the widthwise central portion of the sheet 6 is bent along the conveyance direction by the convex portion 80 and the concave portion 82 (a bead having a U-shaped cross section is formed).

A pair of presser bars 84 as pressing members are rotatably attached to the shaft 79 above the female roller 74 and always hang downward due to their own weight.

A waste tray 86 is disposed on the side of the stiffening roller 70, and can receive and accumulate the photosensitive material 16 sent out from the clamping portion of the stiffening roller 70.

In the center of the waste tray 86, a protrusion placement portion 87 having a substantially chevron-shaped cross section is formed, and the ridged roller 7
As shown in FIG. 4, the photosensitive material 16 fed from the nipping section 0 can be stacked in a mountain shape with the bent section as the apex.

In this case, the photosensitive material 16 accumulated on the protrusion placement portion 87
is pressed against both sides of the bent portion by a presser bar 84 attached to the shaft 79, so that it is held in a chevron-shaped state with the bent portion as the apex.

Next, the operation of this embodiment will be explained.

The photosensitive material 16 pulled out from the magazine 14 is cutter 1
8 and then wrapped around the outer circumference of the rotating drum 20, the rotating drum 20 rotates at high speed and the exposure head 22
The image is exposed.

After exposure, the photosensitive material 16 is peeled off by a scraper 24, coated with water at a water coating section 26, and sent to a thermal development transfer section 28.

On the other hand, the image receiving material 32 in the tray 30 is sent from its top layer to the thermal development transfer section 28 and is brought into close contact with the photosensitive material 16.

The photosensitive material 16 and the image-receiving material 32 after being brought into close contact with each other are sandwiched and transported by a pair of rotating transport rollers 34, 36, and 38. In the process of nipping and conveying by the conveyance roller pairs 34, 36, and 38, heat is transferred from the heater 40 to the photosensitive material 16 and the image receiving material 32 through each conveyance roller pair, and the photosensitive material 16 and the image receiving material 32 are bonded by heat and pressure. 16 is thermally developed, and the recorded image is transferred to the image-receiving material 32 to obtain an image on the image-receiving material 32.

After the transfer, the photosensitive material 16 and the image receiving material 32 are sent to a separating section 42. In the separating section 42 , the photosensitive material 16 and the image receiving material 32 that have been fed are separated from each other by a separating arm 60 .

The image-receiving material 32 separated by the separation arm 60 is conveyed while being held between the endless belt 54 and the endless belt 56 (in the image-receiving material conveyance path 58), and furthermore, at this time, the image-receiving material is conveyed into the endless shape of the endless belt 54. The machine base 1 is dried while being dried by a heater 62 disposed corresponding to the passage 58.
2 onto a take-out tray 64 formed at the top of the tray.

On the other hand, the photosensitive material 16 separated by the separation arm 60
are pinched and conveyed by a pair of conveyance rollers 66 arranged directly below the separation arm 60.

Since an arcuate guide plate 68 is arranged directly below the conveyance roller 66, the photosensitive material 16 is guided by the guide plate 68 and moved to a stiffening roller 70 as a bending means.

In the stiffening roller 70, a male roller 72 and an acid roller 74 rotate under driving force to nip and convey the photosensitive material 16. In this case, since the outer periphery of the acid roller 74 is knurled, the photosensitive material 16 is reliably held and conveyed.

Further, here, a convex portion 80 is formed on the outer periphery of the male roller 72, and a recessed portion 82 is formed on the outer periphery of the acid roller 74, so that the male roller 72 is configured to fit into each other. At this time, the photosensitive material 16 sandwiched and conveyed between the acid roller 74 and the acid roller 74 is bent at its center in the width direction along the conveyance direction by the convex portion 80 and the concave portion 82 (a bead with a U-shaped cross section is formed). It is formed). Therefore, the bending rigidity of the photosensitive material 16 that has passed through the stiffening roller 70 is increased by this bending portion.

In this case, the photosensitive material 16 on the upstream side of the waisted roller 70
Irregular waving may occur as the bead is formed, but since the bead is securely held by the conveying roller 66, this waving is not transmitted to the upstream side of the (7) conveying roller 66. Therefore, the transport of the photosensitive material 16 is not adversely affected.

Photosensitive material 16 sent out from the clamping part of waist b-rough 0
are sent to the waste tray 86. The photosensitive material 16 sent to the waste tray 86 is pressed and held by the presser bar 84 on the protrusion placement portion 87 .

In this case, the photosensitive material 16 accumulated on the waste tray 86 is bent at the center in the width direction along the conveyance direction to increase bending rigidity, and furthermore, the photosensitive material 16 is placed on the protrusion placement section 87 by the presser bar 84. Since both sides of the bent portion are pressed and held in a chevron-shaped state with the bent portion as the apex, they are regularly stacked and accumulated.

Therefore, the apparent volume does not increase when stacked, and the space of the waste tray can be used effectively, making it possible to downsize.

Further, since the stacked photosensitive material 16 is pressed and held by the presser bar 84, curling does not occur again over time.

Furthermore, since the conveyance roller 66, the waist roller 70, and the waste tray 86 are arranged immediately after the photosensitive material conveyance path of the separating section 42, the conveyance path of the photosensitive material 16 after being separated from the image receiving material 32 by the separating section 42 Therefore, the number of parts can be reduced and costs can be reduced.Furthermore, the rigidity is increased by bending, and both sides of the bent part are pressed by the press bar 84 on the protrusion placement part 87. Coupled with the fact that it is held in a chevron-shaped state with the bent portion at the apex, clogging (so-called jam) does not occur.

In this embodiment, the widthwise central portion of the photosensitive material 16 is bent into a U-shaped cross section along the conveyance direction by the convex portion 80 and concave portion 82 of the buckled roller 70 (male roller 72 and female roller 74). However, by changing the shapes of the convex portion 80 and the concave portion 82, the central portion of the photosensitive material 16 in the width direction can be formed into a V-shaped cross section as shown in FIG. 7A). It may also be configured to be folded into a shape, and
As shown in FIG. 7(B), a structure may be adopted in which the center portion of the photosensitive material 16 in the width direction is simply bent.

[Effects of the Invention] As explained above, the image recording device according to the present invention reliably transports the photosensitive material separated from the image-receiving material after an image has been transferred without causing any clogging, and furthermore, the image recording device can transport the photosensitive material separated from the image-receiving material without causing clogging, and can also transport the photosensitive material in a small space. It has the excellent effect of being able to be integrated without waste and realizing this with a simple structure.
