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 to which an image has been exposed and an image-receiving material are superimposed and heated and thermally developed, and the exposed image is transferred to the image-receiving material. An image recording apparatus is known that obtains an image on an image-receiving material.

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 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 curls generated in the photothermographic material are simply accumulated in a waste box without being removed, so this curl increases the apparent volume of the photothermographic material accumulated. However, there is a problem in that the actual amount of waste boxes that can be accumulated 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 Problem C] 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 image-receiving material, the conveyance roller being disposed immediately after the photosensitive material conveying path of the separating means and conveying the photosensitive material separated from the image-receiving material, and the conveying roller of the urine feeding roller. a wavy forming means disposed immediately after the photosensitive material conveyance path to sandwich the conveyed photosensitive material and form a bead along the conveyance direction; and a waste disposed immediately after the photosensitive material conveyance path of the wavy forming means to accumulate the photosensitive material. It includes a tray and a pressing member that presses and holds the photosensitive materials 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 by a conveyance roller, and after a bead is formed along the conveyance direction by a corrugated forming means, it is accumulated on a waste tray. The photosensitive material accumulated on the waste tray is pressed and held by the pressing member.

The photosensitive materials to be stacked have beads formed thereon to increase their rigidity, so that they are regularly stacked and stacked. 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.

In addition, in this case, irregular undulations may occur in the photosensitive material upstream of the undulation forming means due to the formation of beads, but these undulations may occur because they are securely held by the transport rollers. It is not transmitted to the upstream side of the roller, so it does not adversely affect the conveyance of the photosensitive material, and no clogging (so-called jam) occurs.

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.

Examples include color diffusion transfer photosensitive materials, heat-developable photosensitive materials, and photosensitive pressure-sensitive materials. Regarding the above heat-developable photosensitive materials, U.S. Pat. No. 4,463.079, U.S. Pat. , No. 626,

FIG. 5 shows an image recording apparatus IO according to an embodiment of the present invention.

In the image recording apparatus IO, a magazine 14 accommodated in a machine base 12 accommodates a roll-shaped photothermographic material 16 . The photothermographic 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 photothermographic material 16.

The exposed heat-developable photosensitive material 16 is peeled off from the rotating drum 20 by the scraper 24 by rotating the rotating drum 20 in the reverse direction.
After water is applied as an image forming solvent in the water application section 26 , it 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 transport roller pairs 34, 36, 38, which transmits a driving force and receives rotational force, and the photothermographic material 16 and the image receiving material are connected to each other in the gap between each transport roller pair. The material 32 is sandwiched and conveyed in a superimposed state.

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

A separation section 42 is arranged downstream of the thermal development transfer section 28 . As shown in FIG. 2, in the separating section 42, rollers 44, 46, rollers 48, 50, U-rollers 52, and a plurality of tension rollers 53 are arranged, which face each other. An endless belt 54 is wound around the rollers 44 and 48, and an endless belt 54 is wound around the rollers 46, 50, and 5.
An endless belt 56 is wound around 2. 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 is provided near the rollers 44 and 46.
is arranged to separate the photothermographic material 16 and the image receiving material 32 sent out from the thermal development transfer section 28. Therefore, the image-receiving material 32 separated by the separation arm 60 is conveyed while being held between the endless heald 54 and the endless belt 56 (in the image-receiving material conveyance 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 and 2, directly below the separation arm 60, a pair of conveyance rollers 66 are arranged that come into contact with each other, and sandwich the photothermographic material 16 separated by the separation arm 60. It is designed to be transported.

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

The waisted roller 70 includes a plurality of male rollers 72 and a female roller 74.
and axes 76.78. Axis 76.
Reference numeral 78 is connected to a drive source (not shown), whereby the male roller 72 and the female roller 74 rotate under the driving force to sandwich and convey the photothermographic material 16.

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

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 female roller 74, so that they fit into each other. There is. Therefore, the male roller 72 and the female roller 74
At this time, the heat-developable photosensitive material 16 is sandwiched and conveyed between the photothermographic material 16 so that a bead having a U-shaped cross section along the conveyance direction is formed by the convex portions 80 and the concave portions 82 .

A pair of presser bars 84 as pressing members are rotatably attached to the shaft 78 of the female roller 74 and always hang downward due to their own weight.

A waste tray 86 is disposed on the side of the elastic roller 70, and can receive and accumulate the photothermographic material 16 pinched and conveyed by the elastic roller 70.

In this case, the accumulated photothermographic material 16 is pressed against a presser bar 84 attached to the shaft 78.

Next, the operation of this embodiment will be explained.

When the photothermographic material 16 drawn out from the magazine 14 is cut by the cutter 18 and wound around the outer periphery of the rotating drum 20, the rotating drum 20 rotates at high speed and an image is exposed by the exposure head 22.

After exposure, the photothermographic material 16 is peeled off by a scraper 24, coated with water by 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 heat development transfer section 28 and brought into close contact with the heat development photosensitive material 16 . .

The heat-developable 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 pair of conveying rollers 34, 36, 38, heat is transferred from the heater 40 to the photothermographic material 16 and the image receiving material 32 through each pair of conveying rollers, and they are bonded under heat and pressure. The heat-developable photosensitive material 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 transfer, the heat-developable photosensitive material 16 and the image-receiving material 32 are separated into the separating section 4.
Sent to 2. In the separating section 42, the photothermographic 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 held and conveyed by 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 154. 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 photothermographic material 16 separated by the separation arm 60 is pinched and conveyed by a pair of conveyance rollers 66 arranged directly below the separation arm 60 .

Since an arc-shaped guide plate 68 is arranged directly below the conveyance roller 66, the photothermographic material 16 is moved along this guide plate 68.
A waisted roller 7 moves while being guided by the wavy forming means.
Sent to 0.

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

Furthermore, 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 female roller 74, so that the male roller 72 is configured to fit into each other. At this time, the heat-developable photosensitive material 16 sandwiched and conveyed between the convex portion 80 and the concave portion 82
A bead having a U-shaped cross section along the conveyance direction is formed by this.

Therefore, the rigidity of the heat-developable photosensitive material 16 that has passed through the stiffening roller 70 is increased by the beads.

In this case, irregular undulations may occur in the heat-developable photosensitive material 16 upstream of the waisted roller 70 due to the formation of beads, but since they are securely held by the conveyance roller 66, This corrugation is not transmitted to the upstream side of the conveyance roller 66 and does not adversely affect the conveyance of the photothermographic material 16.

The heat-developable photosensitive material 16 nipped and conveyed by the elastic rollers 70 is accumulated on a waste tray 86 .

The heat-developable photosensitive material 16 accumulated on the waste tray 86 is pressed and held by the presser bar 84 .

In this case, beads are formed on the heat-developable photosensitive materials 16 to increase their rigidity, so that they are regularly stacked and stacked. Therefore, the apparent volume does not increase when stacked, and the space of the waste tray 86 can be used effectively, making it possible to downsize. Furthermore, since the heat-developable photosensitive material 16 after the hive is pressed and held by the presser bar 84, curling does not occur again over time.

Furthermore, since the conveying roller 66, the waist roller 70, and the waste tray 86 are arranged immediately after the photothermographic material conveying path of the separating section 42, the image receiving material 32 is separated by the separating section 42.
The transport path of the photothermographic material 16 after being separated from the photothermographic material 16 becomes shorter. This reduces the number of parts and reduces costs.Additionally, the bead formation increases rigidity and prevents blockages (so-called jams).
never occurs.

In this embodiment, the convex portion 80 formed on the outer periphery of the male roller 72 and the recessed portion 82 formed on the outer periphery of the female roller 74 are both formed to have a rectangular cross section, but the present invention is not limited to this. As shown in FIG. 6, a convex portion 88 and a concave portion 90 each having a trapezoidal cross-sectional shape may be used.

[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.
