Abstract

PURPOSE:To use a sensitized material with high efficiency, by providing a cutter which cuts a sensitized material located between a magazine and an exposing part and a light shield part which shields the sensitized material, located between the cutter and the magazine, from external light. CONSTITUTION:Since a portion between a rotary cover and a magazine 14 is shielded from light by means of a light shield plate 98 and a portion between the magazine 14 and a moving platform 64 is shielded from light by means of a light shield plate 120, a rotary cover 88 brings the moving locus of a sensitized material 16 between the magazine 14 and a cutter 18 into a light shield state. Thus, a most of the sensitized material 16 pulled off from the magazine 14 is positioned in the rotary cover 88 and is brought into a state to be shielded from light, a photographic fog is prevented from production. Though there is a possibility that the cut tip part of the sensitized material 16, present between the rotary cover 88 and the cutter 18, is brought into a slight fog state due to release of the cover plate of a machine bed, there is no problem since this part is a part being out of a picture. This constitution eliminates a control means to discharge a fog part, and enables the effective use of the sensitized material 16.

[Summary and operation of the invention]

The present invention is an image recording apparatus that unwinds a roll-shaped photosensitive material housed in a magazine, conveys it to an exposure section, and performs imagewise exposure in the exposure section, and wherein the photosensitive material is provided between the magazine and the exposure section. The apparatus includes a cutter for cutting the material, and a light shielding means for shielding the photosensitive material between the cutter and the magazine from external light.

In this way, in the present invention, since the photosensitive material is always kept in a light-shielded state while being drawn out from the magazine and reaching the cutter,
Even when the cover plate of the main body of the apparatus is opened for the purpose of maintenance or the like, the photosensitive material does not have any exposed parts. Therefore, there is no need for a control means for discarding the overlapping portion, and the photosensitive material can be used effectively.

In the present invention, the type of photosensitive material is not particularly limited.

Any material may be used as long as the image obtained by imagewise exposure can be subjected to processing such as development, transfer, fixing, etc. to obtain a visible image.

For example, there are so-called heat-developable photosensitive materials in which an image obtained by performing the above-mentioned thermal development is transferred to an image-receiving material by heating. In this heat-developable photosensitive material, a movable dye is released in an image form by heating, and the movable dye is transferred to an image-receiving material (dye-fixing material) having a mordant using a solvent such as water.
Transfer is performed to the image receiving material using a high-boiling point solvent, transfer is performed to the image receiving material using a hydrophilic hot solvent built into the image receiving material, or transfer is performed using a mobile dye that is transferred to the image receiving material by thermal diffusion. There are known dye-receiving materials that are dye-transferable or sublimable and transferable to dye-receiving materials such as supports. Specifically, U.S. Pat.

Another example is a so-called photosensitive pressure-sensitive material in which a visible image is obtained by transferring an image generated by imagewise exposure to an image-receiving material having an image-receiving layer by pressure.

This photosensitive and pressure-sensitive material is made by curing a polymerizable compound imagewise by imagewise exposure, as disclosed in, for example, Japanese Patent Laid-Open No. 5'1-1791336 filed by the present applicant, and then overlaying it with an image-receiving material. There is a type that applies pressure to obtain a visible image. This photosensitive and pressure sensitive material has a synthetic polymer resin wall capsule containing a vinyl compound, a photopolymerization initiator, and a colored precursor supported on a support.

Further, there is a type in which a latent image generated by imagewise exposure is subjected to preliminary heat development or wet development, and then overlaid with an image-receiving material and pressure is applied to obtain a visible image. Examples of such materials include JP-A-61-2 filed by the present applicant.
There is one disclosed in No. 78849.

This material is used to obtain an image on an image-receiving material by transferring a color image-forming substance to an image-receiving material having an image-receiving layer after thermal development. A polymerizable compound and a color image-forming substance are coated thereon, and at least the polymerizable compound and the color image-forming substance are encapsulated in the same microcapsule.

Other examples include black and white photographic materials using silver halide, X-ray photographic materials, and conventional color photographic materials.

Therefore, the loaded magazine 14 is accurately positioned in the horizontal plane by the urging force of the leaf springs 72, 76.

Magazine 14 mounted on positioning block 66, 68
A nipping conveyance roller 80.82 is provided between the rotary drum 2o and the rotary drum 2o.
are arranged one above the other, and the holding and conveying rollers 82 receive the driving force of the motor 83 to draw out the photosensitive material 16 from the outer periphery of the roll-shaped winding portion 16A accommodated in the magazine 14. For this purpose, the clamping conveyance roller 82 is horizontally supported on the movable table 64 via a link 84, and the clamping conveyance roller 80 is attached to a rotating cover 88 as a light shielding means.

This rotating cover 88 is pivotally supported by a pin 92 on the movable table 64. This bin 92 is arranged closer to the rotating drum 2o than the nipping and conveying roller 80, and the rotating cover 88
can be rotated as shown in the imaginary line in Figure 1. For this purpose, a handle 94 is attached to the rotating cover 88. Further, a tension coil spring 96 is interposed between the rotary cover 88 and the movable table 64, so that the rotary cover 88 can be rotated to the state shown in solid line in FIG.

Therefore, when replacing the magazine 14, the rotating cover 88 is rotated as shown in the imaginary line in FIG. 1, and the nipping conveyance roller 80 is separated from the nipping conveyance roller 82, so that the vicinity of the tip of the photosensitive material 16 that was being held can be released. It looks like this. Note that a means for locking the rotary cover 88 as shown in the imaginary line in FIG. 1 may be provided.

The rotating cover 88 has a light shielding plate 98 on the surface corresponding to the magazine 14.
is installed. This light-shielding plate 98 is made of a synthetic resin plate or the like bent into a ■-shape, and the negative side thereof is used as a fixed side and is attached to the outside of the rotating cover 88 with double-sided adhesive tape, and the other side is used as a movable side. It hits the outside of the magazine 14 and blocks light between the magazine 14 and the rotating cover 88.

As shown in FIG. 3, this light shielding plate 98 has a pair of slits 100 formed in the middle part on the moving side, so that both longitudinal ends 98A are connected to the frame 14A, and the middle part 98B is connected to the cylinder 14A.

A lower guide plate 104 and an upper guide plate 106 are attached below the rotating cover 88 near the rotating drum 20 of the nipping conveyance roller 80. These are arranged parallel to each other and guide the leading end of the photosensitive material 16 sent out from the nipping and conveying rollers 80, 82 toward the cutter 18 slightly downward.

The cutter 18 has a fixed blade 110 fixed to the machine base 12 and a guide plate 112 arranged above and below the movement trajectory of the photosensitive material 16, and a movable blade 114 movable parallel to the guide plate 112 from the guide plate 112. is also arranged near the rotating drum 20.

The movable blade 114 moves up and down in response to the driving force of a motor (not shown), and engages with the fixed blade 110 to cut the intermediate portion of the photosensitive material 16.

Note that when the rotating cover 88 is rotated as shown in the imaginary line in FIG. 18 is rotating cover 8
Interfering with the rotational movement of 8. z Wordless.

Further, the magazine 14 is shielded by a light shielding plate 120 between the surface opposite to the side where the photosensitive material outlet is provided and the movable table 64, as shown in FIG. This light shielding plate 120 is attached to the positioning blocks 66 and 68 by screws 74.

Note that the gap between the lower surface of the magazine 14 and the moving table 64 may be shielded by a light shielding plate. The light-shielding plate in this case has the same structure as the light-shielding plate 98, with one side bent in the shape of a square square being attached to the moving table 64, and the other side touching the lower surface of the magazine 14.

Next, the operation of this embodiment will be explained.

When installing the magazine 14, move the movable base 64 to the machine base 12.

As a result, the pinching conveyance roller 80 becomes the pinching conveyance roller 82.
and leaves.

In this state, move the magazine 14 to the positioning blocks 66 and 68.
Load it into the. In this case, the magazine 14 is a leaf spring 72.
76 for automatic positioning. That is, the leaf spring 72 presses the surface of the magazine 14 provided with the outlet for the photosensitive material 16 toward the positioning portion 70A, and the leaf spring 76
is a positioning block 68 at one longitudinal end of the magazine 14.
70C of the side surface.

A small amount of the leading end of the photosensitive material 16 is pulled out from the magazine 14 and mounted on the clamping and conveying rollers 82, and the rotary cover 88 is returned to the state shown in solid line in FIG. As a result, the nipping conveyance roller 80 and the nipping conveyance roller 82 nip the vicinity of the leading end of the photosensitive material 16 between them. Further, a light shielding plate 98 blocks light between the rotating cover 88 and the magazine 14.
Furthermore, since the light shielding plate 120 blocks light between the magazine 14 and the moving stage 64, the movement trajectory of the photosensitive material 16 between the magazine 14 and the cutter 18 is in a light-blocked state.

At this point, the mounting of the magazine 14 is completed by moving the moving table 64 along the rail 62 toward the back of the paper in the first drawing and closing the cover plate (not shown) of the machine table 12.

By operating a control button (not shown), the pinching conveyance roller 8
2 receives a rotational force from a motor 83 to cause the leading end of the photosensitive material 16 to protrude slightly beyond the cutter 18 through the lower guide plate 104 and the J guide plate 106. At this point, the movable blade 114 of the cutter 18 is raised and engages with the fixed blade 110 to cut and discard unnecessary portions such as uneven edges of the photosensitive material 16.

At this point, the nipping and conveying roller 80 rotates in the reverse direction, and the leading end of the cut photosensitive material 16 is pulled into the rotary cover 88 and placed on standby.

When the start button (not shown) is pressed, the motor 83
The nipping conveyance roller 82 driven by the photosensitive material 16
The cutter 18 cuts the photosensitive material 16 by a predetermined length, and the cut photosensitive material of the predetermined length is fed into the rotating drum 20. The nipping and conveying roller 82 rotates in reverse and draws the vicinity of the cut end of the photosensitive material 16 into the rotating cover 88 . Therefore, even when an operator removes the light-shielding cover of the machine base 12, external light does not hit the leading end of the photosensitive material 16 pulled out from the magazine 14, and no fogging occurs.

In this way, the cut end of the photosensitive material 16 is placed on the rotating cover 88.
Even if the photosensitive material 16 is not drawn into the magazine 14, most of the photosensitive material 16 pulled out from the magazine 14 is placed inside the rotating cover 88 and is in a light-shielded state, so that no bulking occurs. The cutting edge of the photosensitive material 16 located between the rotary cover 88 and the cutter 18 may be slightly loose due to the opening of the twelfth cover plate of the machine, but this part is outside the image. Therefore, there is no problem.

The photosensitive material 16 cut by the cutter 18 is transferred to a rotating drum 20.
When the drum 20 is wrapped around the outer periphery of the drum 20, the rotating drum 20 rotates at high speed, and an image is exposed by the exposure head 22.

After exposure, the photosensitive material 16 is peeled off by a scraper 24, coated with water by a water coating section 26, and sent to a developing and transferring means 28.

On the other hand, the image-receiving material 32 in the tray 30 is sent from its top layer to the development transfer means 28 and 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 sent to the transport rollers 42.44 through the transport rollers 34.36. Furthermore, it is sent out from between the transport rollers 42, 40 and through the transport rollers 38, 40. When conveyed by multiple pairs of conveyance rollers in this way, since these conveyance rollers are heated by the heater 46, the photosensitive material 16 and the image receiving material 32 are immediately brought to a predetermined temperature, and the photosensitive material 16 is exposed to light. The image is thermally developed and thermally transferred to image receiving material 32.

After the transfer, the photosensitive material 16 and the image-receiving material 32 are separated by a peeling means 48, and the photo-sensitive material I6 is taken out to a waste box 50, and the image-receiving material 32 is taken out via a drying device 52 and onto a take-out tray 54.

In the above embodiments, the present invention is of a type in which the heat development section for the photosensitive material and the heat transfer section from the photosensitive material to the image receiving material are provided at the same location, that is, the heat development transfer is performed simultaneously. The thermal development section and the thermal transfer section may be provided separately.
