Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scanning exposure apparatus, a production method of the scanning exposure apparatus, and a scanning exposure method using the scanning exposure apparatus.

[0002]

2. Description of the Related Art In order to obtain a hard copy from a digital image, many techniques for exposing a photosensitive material have been known. As techniques for this, there are many techniques such as exposing by scanning a laser beam in the main direction while transporting the photosensitive material, and transporting and exposing the photosensitive material in a direction perpendicular to the exposure array. As one of the techniques suitable for miniaturizing the apparatus, there is a technique in which a photosensitive material is conveyed in a direction orthogonal to an exposure array and exposed.

However, the light emitting portion of the light emitting portion of the exposure array, which can be used for the technique of transporting the photosensitive material in the direction orthogonal to the exposure array and exposing the light, has a long wavelength, and a short wavelength corresponding to the blue light. There is a problem that no object can provide a sufficient amount of light.

Therefore, a flat CRT is used instead of an exposure array.
The technology using is described in Japanese Patent Publication No. 2501870 or the like. However, since a CRT scans an electron beam with a magnetic field or an electric field to emit a phosphor, there is a problem that it is difficult to reduce the size of the phosphor.

Further, by applying the technology described in JP-A-7-225433 or JP-A-7-248544, a large-light-emitting LED element is placed at one end of an optical fiber, and the other end of the optical fiber is made of a photosensitive material. However, there is a problem that the device becomes large and complicated.

[0006]

Accordingly, the photosensitive material is conveyed and exposed while being adjacent to the exposure array, so that even if the light amount of the light emitting portion of the exposure array is small, the photosensitive material is exposed. Though an attempt was made to obtain a sufficient amount of light, the shape of the exposure side of the exposure array was often complicated, and it was difficult to transport the photosensitive material without damaging the photosensitive material. In addition, none of the exposure arrays that emit short-wavelength light have high emission intensity.

[0007] In view of the above, it has been considered that the photosensitive material is conveyed to a position separated from the exposure array and exposed through a filter using the exposure array. However, the photosensitive surface of the photosensitive material is positioned within the depth of focus of the image formation. It was difficult to transport while. Also, it was difficult to position the filter. Therefore, the use of an exposure array having a deep focal depth for imaging has been considered, but there is a problem that it is difficult to obtain a sufficient amount of light with an exposure array having a deep focal depth for imaging.

Further, it has been considered that the photosensitive material is positioned by a member that supports the back surface of the photosensitive material. However, if only the back surface of the photosensitive material is supported, the photosensitive surface of the photosensitive material may be lifted, and the positioning is stably performed. There is a problem that cannot be done.

Further, it has been considered that the photosensitive surface of the photosensitive material is positioned by supporting the photosensitive material with a mask plate having an opening near the image forming position of the exposure array. May jam.

An exposure array is provided inside the rotating transparent cylindrical member so that the surface of the transparent cylindrical member is located at the image forming position, and the photosensitive surface of the photosensitive material is brought into close contact with the surface of the transparent cylindrical member. I thought about exposing while moving along with rotation. However, there is a problem that it is difficult to make it inexpensively as shown below. That is, in an exposure array having a small depth of focus, the accuracy required for the transparent cylindrical member is high, and high accuracy is required for all the cylindrical surfaces of the transparent cylindrical member. Therefore, the transparent cylindrical member becomes expensive, and When the cylindrical member is deformed, the focal point is lost, so the strength required for the transparent cylindrical member is high, and when the transparent cylindrical member is thick, the distance between the exposure array and the photosensitive surface of the photosensitive material becomes longer, so the light amount is small. This is because, if the strength is high, the cost is high.

According to the present invention, the apparatus can be downsized, the apparatus can be manufactured at a low cost, a sufficient amount of light can be obtained for the photosensitive material, the structure of the apparatus can be simplified, the photosensitive material is not damaged, and the photosensitive material can be used. It is an object of the present invention to make it possible to perform good exposure without a possibility of jamming and without defocusing.

[0012]

The object of the present invention is achieved by the following claims. Hereinafter, each claim will be described. In addition, the description which overlaps with the cited item will be omitted.

According to a first aspect of the present invention, there is provided a scanning exposure apparatus having an exposure array that forms an image outside, and a transport unit that transports a photosensitive material exposed by the exposure array. A transparent plate is provided at a position between the material and the exposure array, the transparent plate being in close contact with the photosensitive material carried by the carrying means, and a space exists between the exposure array and the transparent plate. Scanning exposure equipment. ], A scanning exposure apparatus having an exposure array that forms an image outside and a transport unit that transports the photosensitive material exposed by the exposure array can be downsized, and the exposure array is formed on the photosensitive material being transported by the transport unit. Since the exposure is performed, the transparent plate in close contact with the photosensitive material can be inexpensive because only the vicinity of the position where the exposure array is exposed needs to have high accuracy. Even if an inexpensive transparent plate is easy to obtain an amount of light and the accuracy is high only in the vicinity of the position where the exposure array exposes, there is a space between the exposure array and the transparent plate, so that focus adjustment is possible and defocusing is possible. And good exposure can be achieved.
Since there is no need to provide an opening in the transparent plate, the possibility of jamming of the photosensitive material can be reduced, and since the photosensitive material does not directly touch the exposure array, the photosensitive material is not easily damaged.

[0014] The "exposure array that forms an image outside" refers to an exposure array in which the image of the light-emitting portion of the exposure array forms an image not at the device surface of the exposure array but at a location away from the device of the exposure array.

An exposure array is an array in which a plurality of optical recording elements such as a liquid crystal element and a shutter element in front of a light emitting element or a light emitting element are arranged in an array. Preferably, at least four or more optical recording elements emit light simultaneously. Examples of the arrangement in an array include a linear arrangement, a parallel arrangement, a staggered arrangement, and a parallel staggered arrangement. Such an exposure array includes an array in which a plurality of LED light emitting elements are arranged as an optical recording element, an array in which a plurality of liquid crystal elements are arranged as an optical recording element in front of an illuminant, and an illuminant. PLZT before
One having a shutter array, one having a plurality of LDs (laser diodes) arranged as light emitting elements in an array, and the other end of an optical fiber having one end connected to an LED light emitting element being arranged in a plurality of arrays. And the like.

[Explanation of claim 2] [The scanning exposure apparatus according to claim 1, wherein the transparent plate has a flat plate portion. By making the image forming position of the exposure array a flat plate portion of the transparent plate, not only can the image formation of the exposure array be good, but also the transport of the photosensitive material near the image forming position of the exposure array can be performed smoothly. The transparent plate and the photosensitive material can be easily brought into close contact with each other in the vicinity of the image forming position of the exposure array, and the transparent plate can be made inexpensive by making the entire transparent plate a flat plate portion.

The transparent plate is preferably a flat plate whose end is rounded, since it is difficult for the photosensitive material to jam at the end of the transparent plate. The transparent plate may be a transparent resin plate such as an acrylic plate. However, a transparent glass plate is inexpensive, and it is preferable because it has durability against the close conveyance of the photosensitive material and heat resistance against the heat generation of the exposure array.

Further, since both surfaces of the transparent plate through which the image-forming light from the exposure array passes are made flat, scattering of the exposure light on the surface of the transparent plate hardly occurs. In addition to improving the tightness of black in the positive photosensitive material, the photosensitive material can be smoothly transported near the image forming position of the exposure array, and the close contact between the transparent plate and the photosensitive material can be improved near the image forming position of the exposure array. Easy to do things. This smooth plane is defined in JIS B 0601-199.
The arithmetic average roughness Ra is 2.0 μm or less at a cut-off value of 0.8 mm and an evaluation length of 4 mm defined by 4, and a cut-off value of 0.25 mm and an evaluation length of 1.25 mm. It is preferable that the arithmetic average roughness Ra is 0.1 μm or less, and particularly, JIS B
0601-1994.
It is preferable that the arithmetic mean roughness Ra is 08 mm, the evaluation length is 0.4 mm, and the arithmetic average roughness Ra is 0.02 μm or less.

[Explanation of Claim 3] In the case of exposing a color photosensitive material, it is preferable to expose each primary color of the color photosensitive material. Therefore, the use of a light emitting unit that emits monochromatic light of each primary color of the color photosensitive material is considered for the exposure array.
It has been found that there is a problem in that the monochromatic light source for color and the monochromatic light source for G color are expensive. Therefore, as shown in FIG. 1, the exposure of the R light is performed by the exposure array 4 which is an R-color monochromatic light source.
Exposure of B and G light is performed by using exposure arrays 51 and 61 for G and B that emit a plurality of primary color lights.
Filters 52 and 62 between the transparent glass plate 33 and
However, there is a problem that the structure between the exposure arrays 51 and 61 and the transparent glass plate 33 becomes complicated, dust easily adheres, it is difficult to remove the adhered dust, and production is difficult. I understood. Therefore, the filter 52,
Considering that 62 is provided in the exposure arrays 51 and 61,
The surface shapes of the exposure arrays 51 and 61 are often complicated,
It has been found that there are problems such as difficulty in mounting and easy removal of the filter. Then, "a color photosensitive material can be exposed, said exposure array emits a plurality of primary color lights, and said transparent plate has wavelength selectivity," Alternatively, the scanning exposure apparatus according to claim 2. This eliminates the need for using an expensive light source such as a B-color monochromatic emission light source or a G-color monochromatic emission light source, simplifies the structure between the exposure array and the transparent plate, makes it difficult for dust to adhere, and It is not necessary to attach a filter to the surface of the exposure array, which is easy to remove dust, is easy to produce, is difficult to attach, and easily peels off the filter, so that exposure can be performed for each primary color of the color photosensitive material.

[Explanation of Claim 4] In the case of exposing a photosensitive material whose photosensitive characteristic changes depending on the exposure wavelength, it is preferable to expose the photosensitive material at several exposure wavelengths.
Therefore, the use of a light-emitting portion that emits monochromatic light of each primary color of the color photosensitive material was considered as the exposure array.
Some monochromatic light sources with the above wavelengths are inexpensive,
It has been found that a monochromatic light source having a wavelength of less than 0 nm has a problem of being expensive. Therefore, we considered making the light emitting unit emit light of a plurality of primary colors and providing a filter between the exposure array and the transparent plate.However, the structure between the exposure array and the transparent plate became complicated, and dust adhered. It was found that there were problems such as easy removal of attached dust and difficulty in production. Therefore, it was considered that a filter was provided on the exposure array. However, it was found that the surface shape of the exposure array was often complicated, and it was difficult to attach the filter and the filter was easily peeled off. Therefore, a light-sensitive material whose photosensitive characteristics change depending on the exposure wavelength can be exposed, and the light emission of the exposure array has a plurality of peak wavelengths within the photosensitive wavelength region of the photosensitive material or the half-width with respect to the peak wavelength is 50 nm or more. 3. The scanning exposure apparatus according to claim 1, wherein the transparent plate has wavelength selectivity. 4. ], It is not necessary to use an expensive light source such as a monochromatic light source having a wavelength of less than 600 nm, the structure between the exposure array and the transparent plate can be simplified, dust is hardly attached, and the attached dust is easily removed. There is no need to attach a filter to the surface of the exposure array, which is easy to produce, is difficult to attach, and easily peels off the filter, making it possible to perform exposure for each primary color of the color photosensitive material.

Examples of the photosensitive material whose photosensitive characteristics change depending on the exposure wavelength include a multi-tone monochrome photographic paper in addition to a color photosensitive material.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, specific examples of the present invention will be described as embodiments, but the present invention is not limited thereto. Further, in the embodiments, although there are definite expressions for terms and the like, they show preferred examples of the present invention, and do not limit the meaning or technical scope of the terms of the present invention.

Embodiment 1 FIG. 2 shows a schematic configuration diagram of a scanning exposure apparatus of the present embodiment.
The scanning exposure apparatus according to the present embodiment includes R, G,
B exposure arrays 41, 51, 61, and conveyance means (not shown) for conveying a silver halide photographic light-sensitive material (hereinafter referred to as “photosensitive material”) 3 exposed by the R, G, B exposure arrays 41, 51, 61. And the photosensitive material 3 conveyed by the conveying means and the R, G, B exposure arrays 41, 51,
The R exposure glass plate 43, which is a transparent plate that is in close contact with the photosensitive material 3 conveyed by the conveyance means,
It has a filter glass plate 53, a B filter glass plate 63, and R, G, B exposure arrays 41, 51, 61, and these R exposure glass plate 43, G filter glass plate 53, B
A space exists between the filter glass plate 63 and the filter glass plate 63.

Thus, the R exposure glass plate 43, the G filter glass plate 53,
The filter glass plate 63 includes an exposure array 4 for R, G, and B.
Processing for improving the accuracy near the position where the exposures 1, 51, and 61 are exposed can be performed at low cost. Also, the glass plate for R exposure 4
3, G filter glass plate 53, B filter glass plate 63
Has a thickness of 1.3 to 1.4 mm, and a sufficient amount of light is easily obtained for the photosensitive material 3. Then, the R, G, B exposure arrays 41, 51, 61 and the R exposure glass plate 43, G
Since there is a space having a thickness of 0.5 to 5 mm between the filter glass plate 53 and the B filter glass plate 63, the image forming position can be adjusted, and the R exposure glass plate 43 and the G filter glass plate 53 can be adjusted. The focus can be adjusted on the surface of the B filter glass plate 63 on the photosensitive material side, and the focus can be adjusted on the photosensitive surface of the photosensitive material 3, so that good exposure without defocusing can be performed. Since there is no opening in the transparent plate, the possibility that the photosensitive material is jammed is low, and the R, G, B exposure array 4
Since the photosensitive material 3 does not directly touch the photosensitive materials 1, 51 and 61, the photosensitive material 3 is not easily damaged.

The exposure array for R of the present embodiment is
300 dp LED light emitting device with a peak wavelength of 665 nm
i. A selfoc lens array, which is a group of lenses having a light emitting element group arranged in a line shape and having a lens function for each LED light emitting element, is arranged at a predetermined position on the front surface of the light emitting element group. is there.

Further, the exposure array 5 for G of the present embodiment
1. Both the exposure array 61 for B emits light in the wavelength range of both the B light and the G light, and as shown in FIG. (ZnO:

A selfoc lens, which is a group of lenses having a light emitting element group in which light emitting elements having a half width of about 100 nm with respect to the peak wavelength of about 300 nm are arranged in a line at 300 dpi and having a lens function for each light emitting element The array is arranged at a predetermined position on the front surface of the light emitting element group.

As a result, an image is formed for each pixel of the light emitting element. Therefore, even if the length of the exposure arrays 41, 51, 61 is increased, the exposure angle is reduced while maintaining the depth of focus by reducing the angle of view of the lens. The distance between the arrays 41, 51, and 61 and the photosensitive surface of the photosensitive material 3 can be maintained, and the thickness and width of the scanning exposure apparatus are not increased.

In addition, since it is made of sheet glass, it is inexpensive, has durability against the tight conveyance of photosensitive material and heat resistance against heat generation of the exposure array, and has both corners in the conveying direction of the photosensitive material. Except for being rounded, since both sides are smooth planes,
Exposure light is not easily scattered on the surface of the transparent plate, which not only improves the white turbidity of the negative photosensitive material and the tightness of black on the positive photosensitive material, but also facilitates the transport of the photosensitive material near the imaging position of the exposure array. And the close proximity of the transparent plate and the photosensitive material in the vicinity of the image forming position of the exposure array can be easily improved. The smooth planes of the R exposure glass plate 43, the G filter glass plate 53, and the B filter glass plate 63 have a cutoff value of 0.8 mm, an evaluation length of 4 mm, and an arithmetic average roughness defined by JIS B0601-1994.

This filter transmits only light of 400 nm to 500 nm, and has wavelength selectivity.

Accordingly, it is not necessary to use a high-output, expensive and inexpensive, low-output light source such as a B-color monochromatic light source or a G-color monochromatic light source.
The structure between the transparent plate and the transparent plate can be made simple, the dust is hardly attached, the attached dust is easily removed, the production is easy, the filter is hard to be attached, and the filter is attached to the surface of the exposure array 51, 61 where the filter is easily peeled. It is not necessary, and it becomes possible to expose each primary color of the color photosensitive material.

The imaging position of each lens of the SELFOC lens array is constant, and the variation of the imaging position is at least within the range of the depth of focus δ. In order to determine the depth of focus, the minimum circle of confusion diameter d is determined by calculating the distance L between pixels at the exposure position.
