DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention belongs to the technical field of an image recording apparatus for recording a latent image by exposing a photosensitive material.

[0002]

2. Description of the Related Art At present, an image photographed on a photographic film (hereinafter, referred to as a film) such as a negative film or a reversal film is printed on a photosensitive material such as photographic paper by projecting light of the film onto the photosensitive material. The exposure is performed by so-called direct (analog) exposure in which the photosensitive material is surface-exposed with the projection light.

In recent years, a printing apparatus using digital exposure, that is, an image recorded on a film is photoelectrically read, and the read image is converted into a digital signal.
Various types of image processing are performed to produce image data for recording. A photosensitive material is scanned and exposed with recording light modulated according to the image data to record an image (latent image), and subjected to development processing to print (photograph). Digital photo printers that output images as such have been put to practical use. According to this digital photo printer, images reproduced on a print are subjected to various processing that cannot be performed by a normal direct exposure printer, such as sharpness (sharpening) processing, partial image correction, and synthesis of a plurality of images and character synthesis. Image processing can be performed. In addition, an image (image data) to be reproduced for printing is supplied as an image file to a computer or various image devices, or
It is also possible to receive an image file from these and reproduce the image.

[0004]

In an image recording apparatus for recording a latent image on a photosensitive material such as a printing device of a photo printer, an image such as a light beam modulated according to a projection light of a film or a recorded image is used. A latent image is recorded on a photosensitive material by exposing the photosensitive material with a recording light carrying the image, but the color density of an image formed on the photosensitive material after development is affected by the temperature of the photosensitive material at the time of exposure. .

A general image recording apparatus has a heat source such as an exposure light source and a power supply. Therefore, by introducing outside air into the apparatus using a cooling fan or the like, the inside of the apparatus is cooled to reduce the internal temperature of the apparatus. The temperature is kept within a predetermined range. In addition, many image recording apparatuses determine a temperature range of an installation environment in which the apparatus can exhibit a predetermined performance. However, even if it is installed in a predetermined environment and further adjusts the temperature inside the device using a cooling fan or the like, it is difficult to keep the temperature inside the device constant with high accuracy, and during the day, In addition, the temperature inside the apparatus fluctuates (the temperature fluctuates during the day). In addition, in order to control the temperature in the image recording apparatus with high accuracy and to prevent the temperature from fluctuating within the day, it is necessary to provide an expensive and high-performance temperature adjusting means, which leads to an increase in the apparatus cost, which is preferable. Absent.

In the conventional image recording apparatus, the temperature of the photosensitive material fluctuates due to the daily fluctuation of the temperature and the like. As a result, the image density recorded on the produced print differs depending on time, resulting in stable high image quality. Images cannot be obtained. In particular, in the above-described digital photo printer, image recording is performed by scanning exposure using a light beam or the like, but it is necessary to increase the scanning speed in order to shorten the exposure time. Since it is used, there is a large change in color density due to such temperature fluctuation of the photosensitive material. Among them, an apparatus that performs exposure after cutting the photosensitive material and develops without passing through a portion such as a reservoir that temporarily stores the photosensitive material. As described above, in an apparatus in which the time from exposure to development is short, the fluctuation in color density is particularly large, which is a problem.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, and there is no fluctuation in the density of a formed image due to a temperature fluctuation inside the image recording apparatus such as a daily fluctuation, and a high-quality image having an appropriate density can be obtained. It is an object of the present invention to provide an image recording apparatus capable of stably creating a recorded finished print.

In order to achieve the above object, the present invention provides a recording means for exposing a photosensitive material with recording light for carrying an image at a predetermined exposure position to record a latent image, Transporting means for transporting the photosensitive material to the exposure position, and transporting the exposed photosensitive material from the exposure position to supply the developing material to the developing device; and An image recording apparatus comprising: a temperature adjusting unit.

The temperature adjusting means may be an atmosphere temperature adjusting means in the vicinity of the exposure position and / or an atmosphere temperature adjusting means in a predetermined area on the upstream side of the exposure position of the photosensitive material transport path by the transport means. preferable.

When the intake fan 24 and the exhaust fan 26 are stopped, it is preferable that the exhaust port 62 be closed by a shutter or the like. Furthermore, it is preferable to provide a filter or the like in the intake fan 24 and the exhaust fan 26 in order to prevent foreign substances such as dust and dirt from entering the housing 20.

In the recording apparatus 10, the supply section 12 includes loading sections 28 and 30, and pull-out roller pairs 32 and 3.
4 and cutters 36 and 38. The loading portions 28 and 30 are portions for loading a magazine 40 in which a long photosensitive material A wound in a roll shape with the recording surface (emulsion surface) outside is housed in a light-shielding housing. Both loading sections usually have a size (width), face type (silk or mat),
A magazine 40 containing photosensitive materials A of different types such as specifications (thickness, type of base, etc.) is loaded. Although the recording apparatus 10 in the illustrated example is an apparatus capable of loading two magazines, the present invention is not limited to this, and the number of magazines that can be loaded may be one, or three. The above magazines may be loadable.

The supply unit 12 pulls out the corresponding photosensitive material A from the magazine 40 by the pair of draw-out rollers 32 and 34, and transports the photosensitive material A to the printer 14 downstream (hereinafter referred to as downstream) in the transport direction of the photosensitive material A. . This conveyance stops when the photosensitive material A conveyed downstream from the cutters 36 and 38 has a length corresponding to the print to be made, and then the cutters 36 and 38 operate to cut the photosensitive material A. Then, a cut sheet having a predetermined length is obtained. In the illustrated example, cutters 36 and 38 are arranged corresponding to the loading units 28 and 30, respectively, but the photosensitive material A supplied from both the loading units 28 and 30 is cut by one cutter. You may.

For example, a dot impact printer, a thermal transfer printer, an ink jet printer, or the like, a non-contact type such as an ink jet printer. The recording method can be suitably used, and in particular, an ink jet printer using a non-water-soluble, room-temperature solid hot-melt ink is preferably exemplified. In the illustrated example, a back print is recorded by the printer 14 while the photosensitive material A cut to a predetermined length is guided by a guide 14a also serving as a platen.

It is preferable that the printer 14 be configured to be capable of printing two or more lines in accordance with a new standard new photo system (Advanced Photo System). In the apparatus shown in the figure, the back print is recorded prior to the exposure. However, in the present invention, in addition, the printer 14 is disposed downstream of the exposure position X, and the back print is recorded after the exposure. The configuration may be as follows.

The recording section 16 scans and conveys the photosensitive material A, exposes the photosensitive material A by so-called digital raster scanning exposure using recording light modulated according to digital image data, and records a latent image. And is composed of an exposure unit 42 and a scanning and conveying unit 44.
The exposure unit 42 is, for example, a light beam L as a recording light.
And an optical unit for performing digital exposure by using a red (R) exposure, a green (G) exposure, and a blue (B) of the photosensitive material A.
A light source that emits a light beam corresponding to each exposure, a modulating unit such as an AOM (acousto-optic modulator) that modulates the light beam emitted from the light source according to digital image data, and a light source that mainly emits the modulated light beam. An optical deflector such as a polygon mirror that deflects in the scanning direction (perpendicular to the plane of FIG. 1), forms an image of a light beam deflected in the main scanning direction at a predetermined position on an exposure position X (scanning line) with a predetermined beam diameter. This is a known light beam scanning device configured to include an fθ (scanning) lens or the like.

As the exposure unit 42, in addition to such a light beam scanning device, a PDP (plasma display) array, an ELD (electroluminescent display) array, an LED (light emitting diode) array, an LCD (liquid crystal display) Various types of digital raster exposure means using an array, a DMD (digital micromirror device) array, a laser array, and other various light emitting arrays or spatial modulation element arrays extending in a direction orthogonal to the scanning and conveying direction can be used.

On the other hand, the scanning and conveying means 44

And 48, and an exposure guide 50 for more suitably holding the photosensitive material A at the exposure position X. The exposure guide 50 holds the photosensitive material A at the exposure position X,
The photosensitive material A is scanned and transported by the transport roller pairs 46 and 48 in a sub-scanning direction (rightward in FIG. 1) orthogonal to the main scanning direction. As described above, since the light beam L is deflected in the main scanning direction, the photosensitive material A is two-dimensionally scanned and exposed by the light beam L modulated according to an image to be recorded, and a latent image is recorded. Is done. In addition, as the scanning conveyance means,
In addition to the above, a scanning transport unit using an exposure drum that transports the photosensitive material Z while holding it at the exposure position X, and two nip rollers that contact the exposure drum across the recording position X, and the like are also preferably exemplified. .

Here, in the recording apparatus 10 according to the present invention, a predetermined space including the exposure position X and the transport region of the photosensitive material A near the exposure position X is surrounded by the exposure unit housing 52. The inside of the exposure section housing 52 is maintained at a predetermined temperature by a temperature adjusting (temperature adjusting) means 54.

As described above, the photosensitive material A at the time of exposure is
Has an effect on the image density obtained after development, and the image density fluctuates with time due to daily fluctuation of this temperature or the like. In particular, as shown in the drawing, a device for performing digital exposure, in particular, a photosensitive material as a cut sheet is exposed, and after the exposure (the photosensitive material A is divided into a plurality of rows as necessary), the photosensitive material is immediately transferred to the developing device 22. Like supplying
In an apparatus in which the time from exposure to development is short, the problem of the density fluctuation is large. In contrast, the recording apparatus 10 of the present invention
, The ambient temperature near the exposure position X is set to a predetermined temperature,
Preferably, by maintaining the ambient temperature near the exposure position X such that the temperature of the photosensitive material A at the time of exposure becomes a predetermined temperature suitable for forming a latent image, the temperature of the photosensitive material A at the time of exposure is kept constant, And it is possible to stably obtain a high-quality image. Further, according to this configuration, the cost is much lower than that of adjusting the temperature inside the housing 20 of the recording apparatus 10 with high accuracy.

The temperature control means 54 is not particularly limited, and various known heating and / or cooling means used for adjusting the ambient temperature can be used. For example, as cooling means,
Examples include a cooling fan, a Peltier element, an air conditioner having a cooling function, and cooling means combining these. Examples of the heating means include a heater, a combination of a heater and an intake fan, an air conditioner having a heating function, a combination thereof, and the like. As described above, since the recording apparatus 10 has many heat sources such as the exposure unit 42, these are used as the heat sources, and for example,
Hot air discharged by cooling the exposure unit 42 or the like may be introduced into the exposure unit housing 52 by a fan to perform heating. Further, in addition to using these heating and cooling means in combination, an air conditioner having a heating and cooling function can be suitably used.

The temperature control means 54 of the present invention is not limited to one having both heating and cooling functions, but may have only one of them. For example, when the target ambient temperature in the exposure unit housing 52 is higher than the highest internal temperature of the housing 20, for example,
In the recording device 10 of the illustrated example, the highest temperature inside the housing 20 is 35 ° C. Therefore, when the ambient temperature in the exposure unit housing 52 is 40 ° C. ± 2 ° C., even if only the heating function is provided. Good.

If necessary, the exposure unit housing 5
2 may have a temperature sensor for detecting the temperature inside. All known temperature detecting means such as a thermistor can be used as the temperature sensor.

Here, when a fan or the like for introducing outside air (inside of the housing 20) is provided as the temperature control means 54, the air intake section into the exposure section housing 52 is provided to prevent dust and dirt from entering. It is preferable to provide a filter or the like.

The temperature in the exposure section housing 52, that is, the temperature in the vicinity of the exposure position X may be appropriately determined according to the type of the photosensitive material A to be used. For example, if the photosensitive material A is Fuji Color Laser Paper CLP-07 (manufactured by Fuji Photo Film Co., Ltd.), the temperature may be about 38 ° C. to 42 ° C.

The photosensitive material A that has been exposed is conveyed to the sorting unit 18. The distributing unit 18 may, if necessary,
The photosensitive material A is distributed in a direction perpendicular to the conveying direction (hereinafter, referred to as a lateral direction for convenience). At present, in general silver halide photographic light-sensitive materials used for photography, development processing and exposure require more time for development processing. It is necessary to temporarily store the material in a stocker or the like. The sorting unit 18 is arranged to solve this inconvenience. The sorting unit 18 sorts the photosensitive material A conveyed in a single row in a horizontal direction orthogonal to the conveying direction to form a plurality of rows overlapping in the conveying direction. This makes it possible to improve the processing capacity of the developing device 22, for example, it is possible to perform less than twice the processing of a single row in the case of two rows and less than three times in the case of three rows. It offsets the time difference.

The sorting device in the sorting unit 18 is not particularly limited, and various methods for sorting the sheet material into a plurality of rows are available. For example, a sorting device using a circular turret rotating about a center, a photosensitive material, and the like. A means for dividing the conveying means of A into a plurality of blocks, for example, three blocks in the conveying direction, and moving and sorting the central block in the horizontal direction, and conveying the photosensitive material A in the downstream direction for mounting and conveying the photosensitive material A A belt conveyor as a means and a lift conveying means for lifting the photosensitive material A using a suction cup or the like and transporting the photosensitive material A in the lateral direction are used to lift the photosensitive material A loaded into the belt conveyor from the upstream and transported to a predetermined position. A device or the like that is conveyed in a horizontal or oblique horizontal (downstream side) direction by a conveying unit and sorted is exemplified.

Further, a sorting device shown in FIG. 2 is preferably exemplified. This sorting device includes five belt conveyors 56 arranged as spaced apart from each other, which are conveying means for conveying the photosensitive material A in the downstream direction (the direction of arrow a in the figure).
And a pair of half-moon rollers (D-rollers) 58 disposed between the belt conveyors 56 to distribute the photosensitive material A by transporting the photosensitive material A in the horizontal direction.

As shown in FIG. 2B, when the photosensitive material A is carried into the sorting device from the upstream, the half-moon roller pairs 58 are in a state where their flat portions face each other. Here, the flat portion of the lower half-moon roller is set to be the same as or slightly below the conveying surface of the belt conveyor 56, so that the conveyance of the photosensitive material A by the belt conveyor 56 or the like does not interfere. When the photosensitive material A is transported to a predetermined position, the half-moon roller pair 58 rotates clockwise in the direction in which the photosensitive material A is distributed, for example, in the case where the photosensitive material A is distributed to the right in the drawing. As shown in FIG. 2C, when the half-moon roller pair 58 rotates, the conveying surface of the lower half-moon roller projects above the conveying surface of the belt conveyor 56, lifts the photosensitive material A from the belt conveyor 56, and The half-moon roller pair 58 sandwiches the photosensitive material A and transports and distributes the photosensitive material A in the lateral direction.

In the recording apparatus 10, the photosensitive material A of all sizes is not necessarily arranged in a plurality of rows, and the photosensitive material A of a large size may be carried into the developing device 16 as a single row. Also, when performing the sorting, the entire size is not sorted into the same number of rows, but according to the size of the photosensitive material A, for example, the L size is sorted into a different number of rows, such as 3 rows of 3 rows and 6 rows of 2 rows. May be performed.

The photosensitive material A, which is distributed in the horizontal direction in the distribution section 18 into a plurality of rows,
Thus, the latent image is supplied from the discharge port 62 to the developing device 16 and subjected to a predetermined developing process according to the photosensitive material A such as a color developing tank, bleach-fixing, and a washing tank, so that the latent image is visualized and then dried. The prints are finished, and are stacked again in a single line in the order of print creation (exposure order) and discharged to a sorter or the like.

Here, the temperature of the photosensitive material A during the period from the exposure to the development affects the latent image formation (stabilization of the latent image), that is, the image density of the obtained finished print. For this reason, it is preferable that the photosensitive material A is kept at a predetermined temperature by, for example, maintaining the atmosphere at a predetermined temperature in the transport area of the exposed photosensitive material A including the distribution unit 18. The temperature at this time may be the same as that of the exposure unit housing 52, for example, when the adjustment of the ambient temperature is used as a means.

FIG. 3 shows a conceptual diagram of another example of the image recording apparatus of the present invention. The image recording device 70 shown in FIG.
The recording device 70 (hereinafter, referred to as a recording device 70) does not have the exposure unit housing 52 and the temperature control unit 54 that are the means for adjusting the ambient temperature near the exposure position X, and transports the photosensitive material A upstream from the exposure position X. Except for having a temperature adjusting section 72 whose temperature is kept at a predetermined temperature in the area, it has basically the same configuration as that of the recording apparatus 10.

In addition, the temperature adjustment unit 7
Inside 2, a temperature adjusting means 78 and a temperature sensor 80 are arranged, and the inside thereof is maintained at a predetermined temperature. Such a temperature adjusting section 72 adjusts the temperature of the photosensitive material A to be conveyed in advance in the transport area of the photosensitive material A upstream of the exposure position X by setting the ambient temperature to a predetermined temperature. As in the case of the exposure section housing 52 and the temperature control means 54, the temperature of the photosensitive material A at the exposure position X is set to a predetermined temperature, preferably a predetermined temperature suitable for forming a latent image. It is intended to suppress the fluctuation of the image density due to this and to obtain a high quality image stably.

In the recording apparatus 70 shown in the figure, the photosensitive material A of the cut sheet supplied from the supply section 12 is carried into the temperature control section 72 through an inlet 76a formed in the partition wall 76, and passes therethrough. The paper is discharged from the outlet 76b, the back print is recorded by the printer 14, and supplied to the recording unit 16. Here, as described above, since the inside of the temperature adjusting section 72 is maintained at the predetermined atmospheric temperature, the temperature of the photosensitive material A is adjusted by passing through the temperature adjusting section 72, and the recording section 16 is controlled at the predetermined temperature. For image recording at the exposure position X.

The temperature control means 78 and the temperature sensor 80
Various examples of the recording device 10 can be used. The ambient temperature of the temperature adjusting section 72 may be the same as that in the exposure section housing 52 of the recording apparatus 10.

The photosensitive material A on which the latent image has been recorded at the predetermined temperature in the recording unit 16 is distributed to the distribution unit 18 in the same manner as in the recording apparatus 10.
Are divided into a plurality of rows in the horizontal direction as necessary, and are supplied to the developing device 22 from the discharge port 62 by the pair of conveying rollers 60.

Although the image recording apparatus of the present invention has been described above, the present invention is not limited to the above embodiment, and various improvements and changes may be made without departing from the gist of the present invention. Of course. For example, the recording device 10 shown in FIG. 1 and the recording device 70 shown in FIG.
Each of them has only the means for adjusting the ambient temperature near the exposure position X and the temperature adjusting unit 72, but the present invention is not limited to this, and may have both of them.
