Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photosensitive material printer, and more particularly to a photosensitive material printer for forming an image using a transmission means such as a liquid crystal panel.

[0002]

2. Description of the Related Art A liquid crystal panel (transmission means) in which a large number of small liquid crystal pieces (micro transmission parts) individually controllable in a transmission state in which a light beam is transmitted and a non-transmission state in which a light beam is not transmitted is arranged in a row direction and a column direction. Are known. Such a liquid crystal panel is, for example, incorporated in a projector and sold by electric appliance manufacturers.

[0003]

Incidentally, it is conceivable to expose a photosensitive material using the above-mentioned liquid crystal panel. For example, irradiating a photosensitive material with digital image light,
Laser exposure devices that form images have the disadvantages of being relatively expensive and vulnerable to vibration.However, if an image is formed using a liquid crystal panel, exposure stability, operability, and equipment costs are low. It is advantageous. However, when a liquid crystal panel is used, there is a problem that image quality is inferior. The reason will be described below.

In a liquid crystal panel, the number of pixels, which is the total number of small liquid crystal pieces, is generally 600 × 800 pixels to 768 × 1024 pixels, which is sufficient for use in a projector or the like. It is not suitable for forming a perfect image.

For example, the entire surface of a photosensitive material having a width of 250 mm is covered with the maximum number of pixels (1) of a commercially available liquid crystal panel.
Assuming that exposure is performed using a pixel having a size of 024 pixels, the number of pixel data (the number of dots) per 2.54 cm (1 inch) is 103 (103 dpi).

Although the number of dots is sufficient for use in digital projectors and high-definition televisions,
The number of pixel data per m (per inch) is 600 to
3000 pcs are insufficient for the photosensitive material required for the application. On the other hand, it is conceivable to maintain the image quality at a certain level or more by limiting the enlargement magnification from the liquid crystal piece, that is, by limiting the width of the photosensitive material to be exposed (that is, the maximum image width). It is convenient if an image can be formed on the image.

In order to form an image on a photosensitive material having a wider width without deteriorating the image quality, it is conceivable to greatly increase the number of liquid crystal pieces in one liquid crystal panel. However, special production of such a liquid crystal panel is not preferable because it causes an increase in cost.

An object of the present invention is to provide a photosensitive material printer which can form an image on a wider photosensitive material while maintaining a certain level of image quality by using a transmission means such as a liquid crystal panel.

[0018]

According to the first photosensitive material printer of the present invention,
A photosensitive material printer for exposing a digital image to a photosensitive material, comprising: a light source for irradiating irradiation light; and a plurality of minute transmitting portions integrated in two dimensions in a row direction and a column direction. Irradiation light, transmission means that can be controlled to be transmitted or non-transmitted in each of the micro-transmitting portions,
Since there are provided a dividing means for dividing the transmitted light from the transmitting means, a means for guiding the transmitted light divided by the dividing means to a predetermined position on the photosensitive material, and a moving means for moving the photosensitive material in a predetermined direction. A case where an image of one screen can be divided and exposed in a width direction (for example, a direction perpendicular to the moving direction of the photosensitive material), whereby the transmitting means has a relatively small number of minute transmitting portions. But 2.54cm
By increasing the number of dots per (1 inch), a high quality image can be formed.

The term "transmission means" used in the present specification refers to means capable of electronically controlling the transmission state of each individual small transmission portion, such as a liquid crystal panel marketed by electric appliance manufacturers. However, it is not limited to this.

It is preferable that the dividing means is a mirror or a prism because a highly accurate dividing means can be constructed.

Further, the transmitted light is divided at predetermined pixel intervals in a row direction or a column direction in which the minute transmission portions are arranged,
A plurality of rectangular digital image light is formed, and by irradiating the photosensitive material in combination with the digital image light, if an image is formed, for example, a short side is short. By forming a plurality of rectangular digital image lights and connecting them in the long side direction, a wide image can be formed.

If the digital image light is arranged and irradiated in a direction perpendicular to the moving direction of the photosensitive material, the digital image light is repeatedly exposed in synchronization with the movement of the photosensitive material. By doing so, a large image can be formed.

Further, when the photosensitive material is exposed while being moved, the end regions of the adjacent digital image light may be exposed by overlapping the same portion of the photosensitive material.
It is possible to form a high-quality image without discontinuity of the connecting portion of the digital image light.

Further, the digital image light is divided into a substantially square shape, and line-exposure is applied to the photosensitive material in a first direction so as to be substantially in a line, and the photosensitive material is irradiated with respect to the first direction. It is preferable that the moving member be moved in a second direction orthogonal to the moving direction. If digital image light having a square shape on both sides is formed, when a lens is arranged between the dividing means and the photosensitive material, the diameter of the lens can be reduced, thereby reducing the size and cost of the configuration.

Further, if the photosensitive material is arranged such that end regions of the digital image light adjacent to each other in the first and second directions overlap and expose the same portion of the photosensitive material, a digital It is possible to form a high-quality image without interruption of the connecting portion of the image light.

If an optical system is disposed between the transmitting means and the dividing means, and the optical system forms the digital image light on or near the dividing means, For example, even when the cross-sectional area of the transmitted light beam transmitted through the minute transmitting portion is large, the cross-sectional area of the transmitted light can be adjusted by the optical system according to the size and shape of the splitting unit. High quality images can be formed.

Further, if an objective optical system is arranged between the dividing means and the photosensitive material, and the objective optical system forms an image of the digital image light on the surface of the photosensitive material, for example, the dividing means Even when the cross-sectional area of the luminous flux of the digital image light from is large, the cross-sectional area of the transmitted light can be adjusted by the objective optical system in accordance with the size of the photosensitive material, and higher image quality can be obtained. An image can be formed.

Since the boundary between the transmission surfaces of the liquid crystal pieces, which are the dividing means, for example, is considered to be unstable in the transmission state, the black state is changed to the non-transmission state, or the boundary between the transmission means and the corresponding boundary. It is preferable to take measures such as not using the portion where the image is formed) as a digital image.

A photosensitive material printer according to a second aspect of the present invention is a photosensitive material printer for exposing a photosensitive material to a digital image, comprising: a light source for irradiating irradiation light; A plurality of micro-transmitting parts are integrated, and the irradiating light from the light source can be controlled to be transmitted or non-transmitted in each of the micro-transmitting parts, and one end facing the transmitting means, A plurality of optical fibers having the other end facing the photosensitive material, and moving means for moving the photosensitive material in a predetermined direction, one end of each optical fiber is located at a predetermined position corresponding to the transmission means. Since they are arranged, the transmitted light transmitted through each of the minute transmitting portions is transmitted to the predetermined position on the photosensitive material without increasing the cross-sectional area (pixel size) of the transmitted light beam by transmitting the light using an optical fiber. Door can be. For example, if the other end of the bundle of optical fibers is formed to have a rectangular shape in which the other end is thinned, the long side can be arbitrarily increased in accordance with the shortening of the short side, whereby a wide image can be formed. At this time, the number of pixels in the direction along the short side is reduced by one exposure, but a large image can be formed by moving the photosensitive material in the direction along the short side.

Further, if the other ends of the optical fibers are arranged in a line in a direction perpendicular to the moving direction of the photosensitive material, a wider image can be formed.

Further, the transmitted light transmitted through the optical fiber is divided at predetermined pixel intervals in a row direction or a column direction in which the minute transmission portions are arranged to form a plurality of rectangular digital image lights. If an image is formed by irradiating the photosensitive material with the digital image light, an image of an arbitrary size can be formed.

Further, an optical system is disposed between the transmitting means and one end of the optical fiber, and the optical system forms an image of the light transmitted through the transmitting means on one end face of the optical fiber or in the vicinity thereof. If this is done, a higher quality image can be obtained by forming an image (focusing) on the end of the optical fiber via the optical system (for example, a lens).

For example, when a liquid crystal panel of 600 × 800 pixels is used, if the liquid crystal panel is divided into four parts, an image of 150 × 3000 pixels can be formed by one irradiation.

Incidentally, in silver halide color paper, 6
If 00 dpi (600 pixels in 2.5 cm (1 inch)), it is equivalent to the pixels of the color paper itself,
It has been found that even if the dots are made finer than that, an image with such a high quality cannot be expected. By the way, 60
0 dpi is a pixel of approximately 41 μm square or round shape. In this case, 600 dpi can be cleared by, for example, enlarging or reducing an image on the end face of the optical fiber with a lens in accordance with the size of one minute transmitting portion of the transmitting means with respect to the diameter of the optical fiber. .

Further, an objective optical system is disposed between the other end of the optical fiber and the photosensitive material, and the objective optical system guides light emitted from the other end of the optical fiber to the photosensitive material. When irradiating the photosensitive material, light can be prevented from being scattered. As such an objective optical system, for example, a selfoc lens (array, plate) marketed by Nippon Sheet Glass Co., Ltd. can be used.
Not limited to this.

Further, it is preferable that the optical fiber is formed as a bundle having a rectangular cross section having a long side corresponding to the width of the transmitting means and a short side substantially orthogonal thereto, and a plurality of the bundles are arranged. For example, if the optical fibers are arranged at random, the correspondence between the pixels of the transmission means and the image formed on the photosensitive material cannot be established, and conversion of digital data becomes troublesome. On the other hand, according to the above-described method, the other end of the optical fiber can be divided into a plurality of blocks, and the conversion at the time of operation facilitates the conversion of digital data.

At one end of the optical fiber, a bundle stacked in the short side direction is arranged corresponding to a row of the minute transmitting portions of the transmitting means, and at the other end of the optical fiber, the bundle is arranged at the long side. It is preferable that they are arranged in a line in the direction.

Further, the short side of the bundle formed on the other end side of the optical fiber is arranged so as to coincide with the moving direction of the photosensitive material, and the short sides of the adjacent bundle are contacted or superposed. This is preferable because it is possible to suppress breaks in the image.

Further, the plurality of bundles include a predetermined number (for example, a relatively small number of 100 to 10000) of optical fibers which are equal to each other, and by forming such a partial bundle, simplification of handling and exposure positioning can be achieved. It can be facilitated. Further, the manufacture of the device can be facilitated, and the data conversion can be simplified. In such a case, an image guide commercially available from Sumita Optical Glass Co., Ltd., Sumitomo Electric Industries, Ltd. or the like can be used. The image guide is formed by bundling thousands to tens of thousands of optical fibers having a diameter of 2 to 14 μm so that the cross section is circular, and using this, the transmitted light from the transmitting means can be transmitted.
The image guide may have a square cross section, and may be arbitrarily shaped, such as a square shape at one end and a slender rectangular shape at the other end.

Further, a layer for reflecting, absorbing or blocking light is provided on the outer periphery of the end of the bundle of optical fibers to prevent the transmitted light from mixing between two or more bundles of adjacent optical fibers. Then, it is possible to prevent the image quality from being deteriorated due to the mixing of light.

If a layer for reflecting, absorbing or blocking light is provided on the outer periphery of the end of each optical fiber to prevent mixing of the transmitted light between two or more adjacent optical fibers, the light can be prevented from being mixed. It is possible to prevent a decrease in image quality due to mixing.

Further, a detecting means for detecting light emitted from the other end of the optical fiber is provided, and the micro-transmitting portion is controlled in accordance with the result of the detecting means to expose a predetermined image to the photosensitive material. Is preferred. For example, in the case of transmitting light using a bundle of optical fibers, the detecting means obtains the relationship between the individual micro-transmission portions and the exposure position of the photosensitive material, and performs digital data conversion based on the detection result. A desired image can be formed. Therefore, it is easy to adjust the displacement of the image. In addition, as such detection, when a photosensitive material printer is installed,
A mode in which adjustment is performed using an inspection jig, a mode in which a sensor is incorporated in a photosensitive material printer in advance, and automatic correction is performed periodically, for example, when power is turned on, can be considered.

Further, the light from the plurality of minute transmitting portions is
In order to enter a single optical fiber, the diameter of the optical fiber is set to be multiple times or more larger than the pixel size from the minute transmitting portion, and when light transmitted from a specific minute transmitting portion enters the plurality of optical fibers. By not using the specific minute transmission portion, if it is controlled so that light transmitted from the specific minute transmission portion is not irradiated on the photosensitive material,
For example, in the case where transmitted light from the same minute transmitting portion enters over a plurality of lines, deterioration of image quality can be prevented by not using such minute transmitting portion. Note that, for example, if digital image light is 20 μm square and transmitted through a large number of thin optical fibers, it is possible to prevent image degradation.

Furthermore, if the transmitting means and the end face of the optical fiber are maintained in a state of contact or close proximity, the transmitting means can transmit the light to the optical fiber.
When transmitted light is transmitted, it hardly needs to pass through the air, so that light attenuation and the like can be suppressed. The term “maintaining the transmission means and the end face of the optical fiber in contact or proximity” means, for example, the case where the transmission means and the end face of the optical fiber are maintained in a state in which they are in direct contact or in close proximity. In addition, when a color coupling unit or the like is interposed between them, a case where the color coupling unit or the like is maintained in close contact or close proximity between the transmission unit and the optical fiber is also included.

And a moving unit for moving the photosensitive material in a predetermined direction, so that the parallel light is stable. An image can be formed using a laser beam, and a lens and the like are not required, so that the configuration can be further simplified. In the case of normal laser exposure, since the polygon mirror is rotated at a high speed to irradiate laser light, there is a problem that exposure unevenness easily occurs due to vibration. Since there is no movable portion in the, it is possible to provide a configuration resistant to vibration.

Further, if a lens is inserted between the transmitting means and the photosensitive material, and the digital image light from the transmitting means is focused on the photosensitive material and exposed, a higher quality image can be formed. it can.

The passage of the light beam is prevented, and when the drive data is “1”, the light beam enters the transmission state, and the light beam is allowed to pass.

FIG. 2 is a perspective view showing the mirror 7. The mirror 7 as a dividing means has a substantially stepped shape, but has inclined reflecting surfaces 7a to 7e. Each reflecting surface 7a to 7e
Can reflect spot (transmitted) light that has passed through the liquid crystal pieces in a predetermined column (vertical) and row (horizontal).

Next, the operation of the photosensitive material printer according to the present embodiment will be described. When a power supply (not shown) is turned on, the controller 18 operates the data write control circuit 11.
To clear the liquid crystal panels 5A to 5C.
The data write control circuit 11 writes "0" into the SRAMs of the liquid crystal panels 5A to 5C to make each liquid crystal piece non-transmissive.

Next, the controller 18 turns on the light source 1. The white light from the light source 1 is converted into parallel light by the projection lens 2, and is converted into dichroic mirrors 3A to 3A.
After separation into each color by C, the transmission color is controlled for each pixel in the liquid crystal panels 5A to 5C.

More specifically, the controller 18 reads out image data (for example, first data obtained by dividing one image into ten parts) from the image memory 9 and sends it to the data conversion circuit 10. The data conversion circuit 10 converts each image data into N-bit drive data. The drive data includes a number of “1” corresponding to the value of the image data. From the driving data of each image, the minimum bit is extracted for each name pixel and sent to the data writing control circuit 11 to be sent to the liquid crystal panels 5A to 5C.
Is written to the SRAM.

Each liquid crystal piece is in a transmission state when the drive data of “1” is given, and transmits component light.
The component light is color-coupled by the color-coupling unit 5D, passes through the objective lens 6, is further reflected by the mirror 7 onto the photosensitive material 8, and exposes the photosensitive material 8 as digital image light. The image is formed thereon in accordance with the movement of the image.

In the printer for photosensitive material according to the present embodiment, at power-on or at regular intervals, the transmitted light from the liquid crystal panels 5A to 5C is detected by an optical sensor (not shown) and compared with the initial state. By doing so, for example, a change in the light amount of the light source 1 with time or a decrease in the light amount due to dirt on a small liquid crystal piece is obtained, and this is automatically corrected.

The optical sensor is provided below the photosensitive material passing therethrough, and when the photosensitive material is not processed, the liquid crystal panel 5A
It is preferable to control transmitted light through 5C to detect transmitted light.

More preferably, one optical sensor is moved by a motor in response to the line exposure so that light from all the liquid crystal pieces can be received, and correction can be made for each liquid crystal piece. That is. In this case, the inter-pixel correction is performed by the feedback of the control, and a clear image can always be obtained. In the case of color light-sensitive materials, for blue, green, and red light,
It is preferable to detect each.

FIG. 3 is a diagram showing the positional relationship between the digital image lights G1 to G5 applied to the photosensitive material 8. Mirror 7
Since the reflecting surfaces 7a to 7e are elongated rectangular shapes and are inclined in a predetermined direction, the digital image lights G1 to G5 also have an elongated rectangular shape as shown in FIG. 3 (in the direction of the arrow in FIG. 3). In this case, by setting the digital image lights G1 to G5 to have a positional relationship in which the digital image lights G1 to G5 overlap in the moving direction of the photosensitive material 8, a continuous image can be formed. When the photosensitive material 8 is further moved, the next image data (second data divided into 10) is added to the photosensitive material 8.
Are exposed further by the digital image light G1 to G5 for the portion indicated by the dotted line, and by repeating this, a high-definition and wide image is formed. In place of the mirror 7, a prism having an internal reflection surface having a similar step shape can be used.

If the mirror 7 is adjusted so that the digital image light is focused on the reflecting surfaces 7a to 7d of the mirror 7 or in the vicinity thereof by the objective lens 6, a higher definition image can be obtained.

FIGS. 4 and 5 show a modification of the present embodiment. As shown in FIG. 4, the digital image light transmitted through the liquid crystal panels 5A to 5C is divided into a substantially square shape by a mirror 7 and irradiated in a direction orthogonal to the moving direction of the photosensitive material 8 as shown in FIG. By doing so, a wider image can be formed. Further, when a lens is provided between the mirror 7 and the photosensitive material 8, the diameter of the lens can be reduced, so that a small-sized configuration can be provided at low cost.

FIG. 6 is a perspective view showing a configuration according to the second embodiment. In the embodiment shown in FIG.
The second embodiment differs from the first embodiment mainly in that an optical fiber 20 is used in place of the mirror 7, and therefore, a common configuration will not be described.

In FIG. 6, the upper ends of the optical fibers 20 are directed toward the liquid crystal panels 5A to 5C, that is, the emission ports of the color combining section 5D (FIG. 1), and the lower ends are positioned on the photosensitive surface of the photosensitive material 8. I am aiming. On the upper end side, the set of optical fibers 20 has a shape similar to the liquid crystal panels 5A to 5C, that is, the exit of the color coupling section 5D. Have been. In addition, a selfoc lens 21 as an objective optical system is disposed between the optical fiber 20 and the photosensitive material 8.

Here, if the exit of the color coupling section 5D and the end face of the optical fiber 20 are kept in contact or close proximity, the transmitted light will be transmitted through the air when transmitted. Almost no light passes, thereby suppressing light attenuation and the like. Note that one end of the three bundles of optical fibers 20 is
The color combination may be performed on the photosensitive material 8 by maintaining the state of being in contact with or in proximity to each of the liquid crystal panels 5A to 5C and distributing the other end side appropriately.

According to the present embodiment, the liquid crystal panels 5A to 5A
Since the spot light from 5C is transmitted by each optical fiber, a wide image can be formed without increasing the pixel size. When the other end of the optical fiber 20 is formed in a single line, the number of pixels in the moving direction of the photosensitive material 8 decreases, but an image of an arbitrary size can be formed by moving the photosensitive material 8. No.

Further, since the objective lens 6 between the liquid crystal panels 5A to 5C and the optical fiber 20 forms the digital image light on the upper end of the optical fiber 20, the digital image light emitted from the other end is formed. Using,
A higher quality image can be formed.

Further, since the selfoc lens 21 is arranged between the optical fiber 20 and the photosensitive material 8, when digital image light is irradiated from the optical fiber 20 to the photosensitive material 8, light scattering is prevented. Further, it is possible to prevent the image light from expanding, and to form a higher quality image.

FIGS. 7 and 8 show a modification of the present embodiment. The optical fiber 20 'shown in FIG. 7 (a) is a bundle having a rectangular shape elongated in the horizontal direction, and its vertical thickness A is divided into, for example, 1/5 in the vertical direction in the liquid crystal panels 5A to 5C. The length of the liquid crystal pieces in the predetermined row is substantially equal to the length of the liquid crystal pieces. As shown in FIG. 7B, a plurality of (five in this example) optical fibers 20 'are vertically stacked so as to have a vertical length corresponding to the liquid crystal pieces of the liquid crystal panels 5A to 5C. . On the other hand, optical fiber 2
The photosensitive material side ends of 0 'are arranged in a line in a long side (lateral) direction, that is, a direction orthogonal to the moving direction of the photosensitive material. Since the optical fiber 20 'is easy to bend, the other end side can be arbitrarily arranged, for example, as shown in FIGS. 8 (a) to 8 (c).
With such an arrangement, digital image light can be emitted for each bundle.

For example, if the optical fibers 20 are randomly arranged, the correspondence between the small liquid crystal pieces of the liquid crystal panels 5A to 5C and the image formed on the photosensitive material 8 cannot be established, and the conversion of digital data becomes troublesome. On the other hand, if the optical fiber 20 is divided into a plurality of blocks (bundles 20 '), it is easy to convert digital data by confirming the operation during operation.

Here, the short side of the bundle formed on the other end side of the optical fiber 20 'is arranged so as to coincide with the moving direction of the photosensitive material 8, and the short sides of the adjacent bundle are contacted or superposed. It is preferable if it is.

When the optical fibers 20 'include a predetermined number (for example, a relatively small number of 100 to 10000) of optical fibers which are equal to each other, forming such a partial bundle simplifies handling and exposure. Positioning can be facilitated. Further, the manufacture of the device can be facilitated, and the data conversion can be simplified.

As shown in FIG. 9, a light-shielding layer 20b for reflecting, absorbing or blocking light is provided on the outer periphery of one end of one optical fiber 20a, so that two or more adjacent optical fibers 20a can be provided. In addition, mixing of digital image light can be prevented, and deterioration of image quality due to mixing of light can be prevented.

Further, as shown in FIG. 10, a light-shielding layer 22 for reflecting, absorbing or blocking light is provided on the outer periphery of the end of the bundle of optical fibers 20 ', so that the bundle of two or more adjacent optical fibers can be connected. In this way, it is possible to prevent the digital image light from being mixed, and to prevent the image quality from being deteriorated due to the mixed light.

A sensor 23 (see FIG. 6) is provided as detecting means for detecting light emitted from the other end of the optical fiber 20, and detects light from the optical fiber 20 when the photosensitive material 8 is not conveyed. A desired image can be formed by adjusting the liquid crystal pieces of the liquid crystal panels 5A to 5C or converting the image data itself according to the detection result.

For example, when light is transmitted using the optical fiber bundle 20, the relationship between each liquid crystal piece and the exposure position of the photosensitive material 8 is determined by the sensor 23, and digital data is converted based on the detection result. Thus, a desired image can be formed. Therefore, it is easy to adjust the displacement of the image. In addition, as such detection,
When the photosensitive material printer is installed, an adjustment is performed using an inspection jig, or a sensor is incorporated in the photosensitive material printer in advance, and automatic correction is periodically performed, for example, when the power is turned on.

Also, as shown in FIG. 11, the transmitted light g1, g2,... From the plurality of small liquid crystal pieces enters the single optical fiber 20a. Thus, the diameter of the optical fiber 20a may be set to be multiple times or more.

On the other hand, as shown in FIG. 12, the transmitted light g1
a and 20a, the specific liquid crystal piece is not used, so that the transmitted light g1 from the specific liquid crystal piece is controlled so as not to irradiate the photosensitive material 8. Image quality can be prevented from deteriorating. still,
If the digital image light is set to 20 μm square and transmitted through a large number of optical fibers having a small outer diameter of 4 μm, it is possible to prevent image deterioration.

FIG. 13 is a view similar to FIG. 1 showing a photosensitive material printer according to the third embodiment. In the present embodiment, a laser light source 30 is used instead of the light source 1. Although the lens 2 and the projection lens 4 are thereby eliminated, the description is omitted because the other configurations are common. Note that an optical fiber may be used instead of the mirror 7.

According to this embodiment, an image can be formed by using a stable parallel laser beam, and a lens and the like are not required, so that the configuration can be further simplified. In the case of ordinary laser exposure, the laser light is emitted by rotating the polygon mirror at a high speed. Therefore, there is a problem that exposure unevenness is likely to occur due to vibration. Since there is no movable part other than the panels 5A to 5C, a configuration resistant to vibration can be provided.

As shown by the dotted line, the liquid crystal panel 5A
An image of an arbitrary size can be formed by providing a lens 31 (means for guiding transmitted light) that reduces before the digital image light from 5C to 5C is irradiated on the photosensitive material 8.

Further, the liquid crystal panels 5A to 5C and the photosensitive material 8
If a lens is inserted between the two, and the digital image light transmitted through the liquid crystal panel is formed into an image on or near a photosensitive material and exposed, a higher quality image can be formed. The lenses 31 can be provided according to the number of the reflection surfaces 7a to 7e.

When the sectional area of the irradiation laser beam is smaller than that of the small liquid crystal piece, the irradiation laser beam and the liquid crystal panel 5A
If a lens is provided between the liquid crystal panels 5A to 5C to irradiate the liquid crystal panels 5A to 5C by enlarging the irradiation laser light, the sectional area of the laser light and the size of the liquid crystal small piece can be made to correspond to each other. A high-quality image can be formed using a suitable laser beam.

In contrast to the embodiment shown in FIG. 1, an exposure system ES (shown by a dotted line in FIG. 1) including liquid crystal panels 5A to 5C has one
It is also conceivable that the light from one light source 1 is guided to the photosensitive material 8 through a plurality of paths by separately providing one or more light sources. According to such a configuration, even if the size of the liquid crystal panels 5A to 5C is small, the image can be divided and formed, and the moving speed of the photosensitive material 8 can be increased, so that a higher quality image can be formed at high speed. can do.

FIG. 14 is a diagram for explaining the fourth embodiment. As shown in FIG. 14A, the digital image light beams G1 and G2 are irradiated onto the photosensitive material 8 so as to polymerize the end portions. However, when the gradation of the image is constant, the digital image light G1, G
Assuming that the light amount of No. 2 is constant, the amount of exposure of the portion S to be superimposed increases, and an image having exposure unevenness is formed.

Therefore, in the present embodiment, the light amounts of the digital image light beams G1 and G2 are compared with the overlapping portions S
In the area corresponding to
, Thereby obtaining a high-quality image without exposure unevenness.

When the image to be formed has a uniform gradation, the total amount of light obtained by superimposing a part of adjacent transmitted light is the light amount of the remaining non-superposed part. If they are approximately equal to each other, the ratio can be set to an arbitrary ratio in a range larger than 0 and smaller than 1, whereby a high-quality image can be formed. If the ratio is 0 or 1,
There is a possibility that streak unevenness may occur.

FIG. 15 is a diagram for explaining the fifth embodiment. In the fifth embodiment, the digital image light G1 is transmitted in the vertical direction, that is, in the moving direction of the photosensitive material 8,
Preferably, the compression is 1/3. Such compression is performed by the photosensitive material 8.
Although it is conceivable to compress the digital image light through a cylindrical lens before the light is applied to the surface, it may be performed by image processing. When the digital image light G1 ′ thus compressed is irradiated onto the photosensitive material 8, the photosensitive image 8 is moved at a constant speed, for example, so that an image of a regular image (aspect ratio 1: 1) is formed. Obtainable. This eliminates the need for an intermittent operation such as stopping the photosensitive material 8 for each exposure, and simplifies the configuration for moving the photosensitive material 8.

It is preferable to have a configuration in which the digital image light transmitted through the liquid crystal panels 5A to 5C is irradiated in a line.

Incidentally, instead of using the dichroic mirrors 3A to 3C, a color separation / color combination prism may be used.
