Abstract

PURPOSE:To effectively utilize the space of an abandoned tray so that the title recorder can be miniaturized by feeding a photosensitive material separated from an image receiving material from a wave-like forming means by means of a forcibly discharging means after beads are formed on the photosensitive material along the carrying direction by means of the wave-like forming means and accumulating the photosensitive material in an accumulating means. CONSTITUTION:A separated photosensitive material 16 is moved under the guidance of a guide plate 68 and fed to rollers with skirt 70 which is a wave-like forming means. At the rollers 70, a male roller 72 and female roller 74 rotate and carry the photosensitive material between them and beads having a U-shaped cross section are formed on the material 16 along the carrying direction by means of the projecting sections 80 of the male roller 72 and recessed sections 82 of the female roller 74. Then the photosensitive material 16 forcibly fed from the holding section of the roller 70 by means of a discharging roller 92 is accumulated in an abandoned tray 86. Since the photosensitive material 16 thus accumulated is increased in rigidity due to the beads, the material 16 is regularly piled up. Therefore, the apparent volume of the piled up material 16 does no increase and the space of the abandoned tray 86 can be utilized effectively. Thus this picture recorder can be miniaturized.

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 thermal photosensitive 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 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 device that obtains an image on an image-receiving material by separating the photosensitive material from the separated photosensitive material and forming a bead along the transport direction; a forced ejection means that engages with the photosensitive material and sends out the photosensitive material from the waveform forming means; and an accumulation means that is disposed immediately after the photosensitive material conveying path of the waveform forming means and collects the photosensitive material sent out by the forced ejection means. We are prepared.

[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. Beads are formed in the separated photosensitive material along the transport direction by a wave forming means. Furthermore, the photosensitive material on which the beads have been formed is forcibly sent out from the corrugated forming means by the forced ejection means, and is accumulated in the accumulating means.

In this case, since the photosensitive material on which the bead is formed is forcibly sent out from the waveform forming means by the forced ejection means, clogging (so-called jam) of the photosensitive material does not occur during or after bead formation. It is reliably accumulated in the accumulation means.

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 stacking means can be used effectively, making it possible to downsize.

In this case, if a pressing member is provided to press and hold the stacked photosensitive material, curling will not occur again over time.

Furthermore, by providing a conveyance roller that clamps the photosensitive material upstream of the wave forming means, even if irregular undulations occur in the photosensitive material due to the formation of beads, these undulations can be prevented by the conveyance rollers. Also, there is no possibility that the liquid will be transmitted to the upstream side, and the transport of the photosensitive material will not be adversely affected, and clogging will not occur.

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.

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 optical material 16 is peeled off from the rotating drum 20 by a scraper 24 as the rotating drum 20 is reversed, and after being applied with water as an image forming solvent in a water application section 26, it is transferred to a thermal development transfer section 28. is sent.

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 belt 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 is provided near the rollers 44 and 46.
is arranged to separate the photosensitive 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 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 and 2, a pair of conveyance rollers 66 are arranged directly below the separation arm 60 and are 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 wave forming 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 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 nip and convey the photosensitive material 16.

The outer periphery of the female roller 74 is knurled to ensure that the photosensitive material 16 can be held therebetween.

A convex portion 80 having a rectangular cross section is formed on the outer periphery of the axially intermediate portion of the male roller 72, and a concave portion 82 similarly having a rectangular cross section is formed on the outer periphery of the axially intermediate portion of the female roller rough 4. They are designed to fit into each other. Therefore, when the photosensitive material 16 is conveyed while being held between the male roller 72 and the female roller 74, a bead having a U-shaped cross section along the conveying direction is formed by the convex portions 80 and the concave portions 82. It looks like this.

As shown in FIGS. 1 to 3, a discharge roller 92 serving as a forced discharge means is provided between each male roller 72.
Similarly, it is attached to a shaft 76 and rotates together with the shaft 76, that is, the male roller 72.

A plurality of continuous wedge-shaped notches 94 are formed on the outer periphery of the discharge roller 92, forming a ratchet tooth shape as a whole. The tip of this notch 94 is connected to the discharge roller 92.
In other words, wall surfaces 94A along the radial direction of the discharge roller 92 are formed to face the rotation direction, and in this embodiment, the depth of the wall surfaces 94A is 2 mm. There is.

This discharge roller 92 is used to remove the photosensitive material 1 on which beads are formed.
6 is separated from the waist roller 70 (when the clamping is completed), the wall surface 94A of the notch 94 engages with the rear end of the photosensitive material 16, presses it and guides it, and as it rotates, The photosensitive material 16 is forcibly sent out downward (along the direction of rotation) from the nipping portion between the male roller 72 and female roller 74 of the stiffening roller 70.

A pair of presser bars 84 as suppressing 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 as a collection means is arranged on the side of the elastic roller 70, and the photosensitive material 1 that has been forcibly sent out from the clamping portion of the elastic roller 70 by the discharge roller 92 is disposed on the side of the elastic roller 70.
6 can be taken and accumulated by Uke. In this case, the accumulated photosensitive material 16 is pressed against a presser bar 84 attached to the shaft 78.

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
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 photosensitive material 16 is guided by this guide plate 68 and moved to a stiff roller 70 as a wave forming means.

In the elastic roller 70, a male roller 72 and a female roller 74 rotate under driving force to nip and convey the photosensitive material 16. In this case, since the outer periphery of the female roller 74 is knurled, the photosensitive 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 photosensitive material 16 sandwiched and conveyed between the rollers 72 and the female rollers 74 forms a bead with an opening-shaped cross section along the conveyance direction by the convex portions 80 and the concave portions 82 . Therefore, the photosensitive material 16 that has passed through the stiffening roller 70
The stiffness is increased by this bead. In this case, irregular waving may occur in the photosensitive material 16 upstream of the waisted roller 70 due to the formation of beads;
Since the photosensitive material 16 is securely held between the conveyance rollers 66, the undulations will not be transmitted to the upstream side of the conveyance rollers 66, and will not adversely affect the conveyance of the photosensitive material 16.

When the rear end of the photosensitive material 16 being conveyed while forming a bead passes through the stiffening roller 70 (at the time when the nipping is completed), the wall surface 9 of the notch 94 formed in the discharge roller 92
4A engages with the rear end of the photosensitive material 16 and guides it while pressing it, and as the discharge roller 92 rotates, the photosensitive material 16 is moved between the male roller 72 and the female roller 7 of the waist roller 70.
4 and is forcibly sent out downward (in the direction of arrow B in FIG. 2). Therefore, the photosensitive material 16 does not become jammed (so-called jam) between the male roller 72 and the female roller 74 of the elastic roller 70 during or after forming the bead with the elastic roller 70, and is fed out reliably. It will be done.

The photosensitive material 16 forcibly sent out from the clamping portion of the stiffening roller 70 by the discharge roller 92 is accumulated on the waste tray 86. Photosensitive materials 1 accumulated in waste tray 86
6 is pressed and held by a presser bar 84.

In this case, the photosensitive materials 16 to be stacked have beads formed thereon to increase their rigidity, so that the photosensitive materials 16 are stacked regularly. 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. 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 becomes shorter. For this reason, the number of parts can be reduced and costs can be reduced, and this is combined with the fact that a bead is formed and the rigidity is increased, and the discharge roller 92 forcibly sends out the material from the clamping portion of the waisted roller 70. Therefore, no clogging (so-called jam) occurs.

In this embodiment, a wedge-shaped notch 94 is formed on the outer periphery of the discharge roller 92 as a forced discharge means, but the present invention is not limited to this, and as shown in FIG. A configuration may be adopted in which a discharge roller 98 is provided with a portion 96.

Next, a second embodiment of the present invention will be described. Components that are basically the same as those in the first embodiment are given the same reference numerals as those in the first embodiment, and their explanations are omitted.

FIG. 7 shows a stiffening roller 100 according to a second embodiment.

The elastic roller 100 is composed of a male roller 102 and a female roller 104, and rotates in response to driving force to nip and convey the photosensitive material 16.

A convex portion 106 having a rectangular cross section is formed on the outer circumference of the male roller 102 as in the first embodiment, and a concave portion 108 having a rectangular cross section is similarly formed on the outer circumference of the female roller 104. They are designed to fit into each other. Therefore, the stiffening roller 100 is capable of forming a bead in the photosensitive material 16 that has a cross-sectional shape along the conveying direction.

The outer peripheral portion 106A of the convex portion 106 is provided with flat knurling as a forced ejection means. This outer peripheral portion 106A
engages with and guides the photosensitive material 16 being conveyed while forming beads, and as in the first embodiment,
As the male roller 102 rotates, the photosensitive material 16 is forcibly moved downward from the sandwiched portion with the acid roller 104 (arrow C in FIG. 7).

The outer peripheral part 106A of the convex part 106 formed on the acid roller 102 engages with the photosensitive material 16 and guides it while pressing it.
04 is forcibly sent out downward (along the rotational direction). For this reason, the photosensitive material 16 is not jammed (so-called jam) between the male roller 102 of the elastic roller 100 and the acid roller 104 during or after forming the bead by the elastic roller 100, and is fed out reliably. It will be done.

In addition, beads are formed on the photosensitive material 16 to be stacked to increase its rigidity, and the ladle is regularly stacked and stacked, making it possible to effectively utilize the space of the waste tray 86 and downsize. becomes.

In each of the above embodiments, 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 acid roller 74, and the convex portion 106 formed on the outer periphery of the male roller 102 and the acid roller A recess 10 formed on the outer periphery of 104
8 is configured to have a rectangular cross section, but the configuration is not limited to this, and a configuration may be adopted in which the convex portion 110 and the concave portion 112 have a trapezoidal cross section as shown in FIG.

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