[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a photographic processing apparatus that performs digital exposure.
[0002]
[Prior art]
With the recent development of digital technology and accompanying digital devices, there is a wave of digitization in the photographic processing industry. As an example, it replaces the conventional analog exposure method in which an original image of a photographic film is printed on a photosensitive material via an optical lens system, and the original image of a photographic film is read by a scanner and converted into digital data, which is created based on this digital data. A digital exposure method in which an image to be printed is printed on a photosensitive material through a digital device has been adopted.
[0003]
The digital exposure method includes a method using a combination of an optical fiber and a PLZT element (translucent piezoelectric ceramic element), and a method using a DMD (digital micromirror device) (registered trademark) (hereinafter abbreviated as “DMD”). A method using a combination of a laser beam and a polygon mirror is provided. In any method, there is a so-called scanning exposure method in which a line-shaped exposure is performed while a photosensitive material is conveyed at a constant speed. The majority.
[0004]
Therefore, in a photographic processing apparatus that employs a scanning exposure method, an exposure table that can carry with high feed accuracy corresponding to minute digital dots, and a photosensitive material on the exposure table based on digitized photographic film image data. A scanning exposure unit for irradiating scanning light for exposure is essential.
[0005]
[Problems to be solved by the invention]
Here, since the exposure table and the scanning exposure unit are completely independent in terms of mechanism, in the apparatus design, the concept that they are separately mounted and arranged in the apparatus main body is generally employed. . In this case, the photosensitive material is scanned and exposed unless the conveying direction of the photosensitive material on the exposure table and the conveying direction of the photosensitive material sent from the other upstream conveying unit are exactly matched. Since multiple dot images do not overlap neatly and a correct print image cannot be obtained, normally, before shipping from the factory, first adjust the position of the exposure table with respect to the photosensitive material transport direction, and then set the scanning exposure unit. The position is adjusted so as to fit the exposure table. However, the following problems occur in the photo processing apparatus having such a configuration.
[0006]
The first problem is that if the position of the exposure table has to be readjusted for maintenance at a later date, or if the exposure table has to be removed once for repair, repair, replacement, etc., the position of the exposure table has changed from the initial position. Since the position is slightly shifted, it is necessary to re-adjust the position of the scanning exposure unit, which makes the adjustment work extremely complicated.
[0007]
The second problem is that in the main body of the apparatus, vibrations of the motor when transporting the photosensitive material, vibrations of the motor driving the transport rack in the development processing unit, vibrations of the drying fan, etc. occur. When different exposure tables and scanning exposure units receive these external vibrations and vibrate slightly at different frequencies, image misalignment occurs during scanning exposure and stripes occur on the print.
[0008]
Accordingly, the present invention has been made to solve the above-described problems, and can simplify the position adjusting operation of an exposure table for conveying a photosensitive material and an exposure unit for exposing the photosensitive material on the exposure table. In addition, another object of the present invention is to provide a photographic processing apparatus that is less affected by external vibrations such as a motor and a fan for the exposure table and the exposure unit.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, a photographic processing apparatus according to the present invention includes an exposure table 13 for transporting the photosensitive material P, and digitally converts the photosensitive material P on the exposure table 13 based on the digitized image data of the original image. In the photographic processing apparatus comprising an exposure unit 14 for exposure in the apparatus main body 1, the exposure table 13 and a mounting table 122 for mounting the exposure unit 14 are provided in the apparatus main body 1. Is positioned on the mounting base 122 by the first positioning means, and the exposure base 13 is positioned on the mounting base 122 by the second positioning means so as to be in an appropriate position with respect to the exposure unit 14, and The mounting base 122 is configured to be position-adjustable with respect to the apparatus main body 1.
[0010]
According to the photographic processing apparatus having the above configuration, when the exposure table 13 and the exposure unit 14 are mounted on the mounting table 122, they are positioned in an appropriate positional relationship. From this state, the position of the mounting base 122 is adjusted with respect to the apparatus main body 1, and the photosensitive material P in the other transport units positioned on the upstream side of the exposure stage 13 and in the transport direction of the photosensitive material P on the exposure stage 13. Match the transport direction. Thereby, the position adjustment of the exposure table 13 and the exposure unit 14 is completed.
[0011]
According to the photographic processing apparatus of the present invention, the first reference surface for mounting the exposure unit 14 and the second reference surface for mounting the exposure table 13 on the mounting table 122 as described in claim 2. And a configuration in which the first reference surface and the second reference surface are set to be orthogonal to each other can be employed.
[0012]
According to the photographic processing apparatus having the above configuration, the irradiation direction of the light irradiated from the exposure unit 14 is parallel to the first reference plane and orthogonal to the second reference plane, while the photosensitive material P is conveyed in the exposure table 13. If the exposure table 13 and the exposure unit 14 are positioned so that is parallel to the second reference plane and orthogonal to the first reference plane, the two are in an appropriate positional relationship.
[0013]
Furthermore, in the photographic processing apparatus according to the present invention, as described in claim 3, the exposure unit 14 is positioned on the mounting base 122 by engaging the first reference surface and the exposure unit 14 in at least two places. On the other hand, the second reference surface and the exposure table 13 are concavo-convexly fitted at one place, and the engaging body 144 protruding from the second reference surface and the outer edge of the exposure table 13 are engaged, whereby the exposure table 13 Can be adopted that is positioned on the mounting base 122.
[0014]
According to the photographic processing apparatus having the above-described configuration, the movement of the exposure unit 14 along the first reference surface is regulated by the concave and convex fitting between the first reference surface and the exposure unit 14 in at least two places. The exposure unit 14 is positioned. Then, the second reference surface and the exposure table 13 are concavo-convexly fitted at one place, so that the exposure table 13 can be rotated along the second reference surface. Is restricted, and the exposure table 13 is positioned.
[0015]
Further, in the photographic processing apparatus according to the present invention, it is more preferable to adopt a configuration in which the locking body 144 is an eccentric cam rotatable along the second reference plane.
[0016]
According to the photographic processing apparatus having the above-described configuration, the rotational position of the exposure table 13 can be adjusted with respect to the second reference surface by adjusting the rotation of the eccentric cam. As a result, when the exposure unit 14 adopts, for example, a scanning exposure method, the conveyance direction of the photosensitive material P on the exposure table 13 and the scanning direction of the scanning light can be accurately orthogonally crossed on the photosensitive material. It is possible to obtain a correct print image in which a plurality of point images subjected to scanning exposure are neatly overlapped. The reason for adopting such a configuration is that, in the relative positional relationship between the exposure unit 14 and the exposure table 13 when the scanning exposure method is used, there is a relationship between the conveyance direction of the photosensitive material P on the exposure table 13 and the scanning direction of the scanning light. This is because the orthogonality is strictly required.
[0017]
Furthermore, the photographic processing apparatus according to the present invention can employ a configuration in which a vibration isolating material 134 is disposed between the mounting base 122 and the apparatus main body 1 as described in claim 5. According to the photographic processing apparatus having such a configuration, the vibration of the motor generated when the photosensitive material P is conveyed, the vibration of the motor driving the conveyance rack in the development processing unit, the vibration of the drying fan, etc. External vibration is not transmitted to the exposure table 13 and the exposure unit 14, and image displacement due to minute vibrations of the exposure table 13 and the exposure unit 14 at mutually different frequencies can be suitably prevented.
[0018]

The detailed configuration of the exposure processing unit 11 according to the present embodiment is as described above. Next, an adjustment method of the exposure processing unit 11 will be described with reference to FIG. The adjustment of the exposure processing unit 11 is performed by irradiating the appropriate position of the scanning exposure region on the exposure table 13 with the scanning light, and the photosensitive material of the other conveyance units (particularly the first conveyance unit 7) and the exposure table 13. The purpose is to match the transport directions.
[0061]
First, the pins 135 and 135 of the reference mounting base 123 are formed on the lower surface of the optical box 157 on the assumption that the lower surface of the optical box 157 and the irradiation direction of the scanning light emitted from the optical box 157 are parallel. The optical box 157 is placed on the reference mounting base 123 by fitting the concave and convex portions so as to be fitted into the two holes. At this time, since the lower surface of the optical box 157 and the first reference surface of the reference mount 123 are in contact with each other, the irradiation direction of the scanning light from the optical box 157 is parallel to the first reference surface.
[0062]
Next, the pin 143 projecting from the end surface 136b of the left plate 136 is concavo-convexly fitted so as to be fitted into a circular hole drilled in the central portion on the one end side of the mounting surface 140 of the exposure table 13, and the mounting surface 140 is fitted. One end side of the exposure plate 13 is brought into contact with the end surface 136b of the left side plate 136, and the other end side of the mounting surface 140 is brought into contact with the end surface 137b of the right side plate 137, and then the bolts inserted into the four positions of the exposure table 13 are inserted. 141 are screwed into female screws formed on the end surfaces 136b and 137b of the plates 136 and 137, respectively, so that the exposure table 13 is lightly fixed to the exposure table mounting table 124.
[0063]
From this state, the eccentric cam 144 is rotated and adjusted to adjust the tilt of the exposure table 13, and the scanning direction of the scanning light and the axial direction of the roller are parallel, that is, the scanning direction of the scanning light and the exposure table After making the conveyance direction of the photosensitive material P orthogonal, the four bolts 141 are fastened to firmly fix the exposure table 13 to the exposure table mounting table 124.
[0064]
As described above, the optical box 157 (the scanning exposure unit 14 is placed on the upper surface (first reference surface) of the reference mounting table 123 and the exposure table 13 is mounted on the end surfaces 136b and 137b (second reference surface) of the exposure table mounting table 124. , And by adjusting the tilt of the exposure table 13 using the eccentric cam 144, the proper positional relationship between the scanning exposure unit 14 and the exposure table 13 can be obtained. Appropriate scanning light is irradiated to the region.
[0065]
Next, after loosening the nut 131 fastened to the bolt 130, the screwing position of the nut 131 with respect to the bolt 130 is changed, and the reference mounting base 123 is moved slightly in the horizontal direction, so that the axial length of the roller of the exposure base 13 is increased. The direction of the roller and the axial length direction of the rollers of the first transport unit 7 are made parallel, and the transport direction of the photosensitive material P in the first transport unit 7 and the transport direction of the photosensitive material in the exposure table 13 are matched, Are fastened to fix the reference mounting base 123 (second base 121) to the first base 120.
[0066]
As described above, the relationship between the scanning exposure unit 14 and the apparatus main body 1 (other transport unit) and the exposure table 13 and the apparatus main body 1 (others) can be obtained only by adjusting the inclination of the reference mounting base 123 and the horizontal position. Therefore, it is possible to obtain a correct print image in which a plurality of point images scanned and exposed on the photosensitive material on the exposure table 13 are neatly overlapped.
[0067]
The adjustment method of the exposure processing unit 11 according to the present embodiment is as described above. According to the exposure processing unit 11 according to the present embodiment, the scanning exposure unit 14 is simply mounted on the reference mounting base 123 and is attached to the reference attachment. Positioned on the stage 123, the exposure stage 13 is positioned on the exposure stage mounting stage 124 simply by being attached to the exposure stage mounting stage 124 and rotating the eccentric cam 144, so that either of the scanning exposure unit 14 or the exposure stage 13 is positioned. Even if it is once removed and then attached again, as long as the eccentric cam 144 is not touched, the relationship between the two remains maintained, so that a re-adjustment operation is unnecessary.
[0068]
Further, since the scanning exposure unit 14 and the exposure table 13 are integrally attached to one member (a mounting table 122 including the reference mounting table 123 and the exposure table mounting table 124), the scanning exposure unit 14 and the exposure table 13 are mounted. Thus, it is possible to perform an adjustment operation on the apparatus main body 1 (another transport unit) while maintaining the above relative relationship. Moreover, even if one of the scanning exposure unit 14 and the exposure table 13 is once removed by repair, repair, replacement or the like and then attached again, as long as the nuts 131, ... and the eccentric cam 144 are not touched, Since the relationship between the two and the apparatus main body 1 (another transport unit) is maintained, the adjustment work between the two and the apparatus main body 1 is unnecessary.
[0069]
Next, an operation mode of the cooling device for forcibly cooling the halogen lamp 155 will be described with reference to FIG.

[0071]
Then, the air in the apparatus main body 1 is sucked into the lamp house 156 through the air filter 168. Dust, dust, paper dust and the like are removed by the air filter 168 from the sucked air, and first circulates while bending between the light shielding plates 180 in the light shielding body 167.
[0072]
Then, the air that has exited the opening 181 of the light shielding body 167 flows from the opening 173 into the ventilation guide body 166. Therefore, the air is guided between the two guide plates 174 and 174 to the opening 160 formed at the lower side of the side surface of the ventilation guide body 166. At this time, the base end portion of the reflector 170 and the sealing portion 171 interposed on the flow path are exposed to the flowing air and are forcibly cooled. Thereafter, the air that has cooled the halogen lamp 155 flows through the duct 161 and is then exhausted to the outside of the apparatus main body 1.
[0073]
As described above, not only the entire halogen lamp 155 is cooled by the air flow in the lamp house 156, but also the sealing portion 171 that is particularly susceptible to thermal damage is suitably cooled, thereby extending the life of the halogen lamp 155. be able to.
[0074]
In addition, by adopting a labyrinth structure including a plurality of light shielding plates 180,... In the lamp house 156, it is possible to regulate the intrusion of light without hindering the circulation of the cooling air of the halogen lamp 155. It is possible to prevent the photosensitive material P from being inadvertently exposed to stray light that has entered the optical box 157.
[0075]

[0077]
Further, the exposure method is not limited to the scanning exposure method, and even if it is a scanning exposure method, a scanning exposure method in which the photosensitive material P is stopped, and the exposure unit side moves to scan exposure. It may be a method of performing.
[0078]
Furthermore, the digital image data related to digital exposure is not limited to the case of collecting from an image of a photographic film, and may be an image created on a computer, for example, an image taken with a digital camera. Alternatively, it may be an image of a printed matter that can be read by the scanner device.
[0079]
Further, the configuration for adjusting the position of the mounting base (in particular, the tilt adjustment) and the configuration for adjusting the tilt of the exposure table are not limited to the above-described embodiments, and the configuration for positioning the exposure unit and the exposure table is also included in the above-described embodiments.

Therefore, even if one of the exposure unit and the exposure table is once removed and then reattached, the positional relationship between the exposure unit and the exposure table is maintained. Adjustment work can be eliminated.
[0081]
In addition, since the mounting base on which the exposure unit and the exposure table are mounted is configured to be adjustable with respect to the apparatus main body, either the exposure unit or the exposure table is removed once for repair, repair, replacement, etc. Even in the case of mounting, the relationship between the mounting base and the apparatus main body is maintained, and it is possible to eliminate the adjustment operation between the exposure unit and the exposure base and the apparatus main body.
[0082]
Furthermore, by attaching the exposure unit and the exposure stand to one mounting stand, external vibration such as vibration of the motor when transporting the photosensitive material, vibration of the motor driving the transport rack in the development processing section, vibration of the drying fan, etc. Since it is difficult for the exposure unit and the exposure table that have received vibrations to vibrate slightly at different frequencies, for example, in a photographic processing apparatus that performs scanning exposure, image misalignment occurs during scanning exposure, and the image is printed on the print. It is possible to solve the problem of occurrence of uneven stripes.
