Description

  The present invention relates to a photographic processing apparatus for measuring a test print and correcting processing conditions.

  In general, in a photographic processing apparatus, various processing conditions are corrected in order to perform these optimum processes before the exposure and development processes are started. Performing this correction is called setup work. The setup operation is performed by measuring the color development state of the developed test print (test photosensitive material used for the setup operation) and correcting the processing conditions based on the result.

As a photographic processing apparatus that performs such setup work, a colorimeter, which is a means for measuring the color development state of a test print, is provided in the photosensitive material discharge section in the drying processing section, and automatically after the test print is discharged. There has been proposed one that performs colorimetric measurement and performs setup (see Patent Document 1).
For example, the set-up operation can be completed automatically without the intervention of an operator, such as when the discharged test print is manually set in a colorimeter and colorimetry is performed.

The pressure-conveying roller pair 57 is configured by combining two rollers, and conveys the photographic paper P to the downstream side by rotating the photographic paper P in pressure contact with a gap between the two rollers. The chucker-type conveyance unit 58 conveys the downstream side (front end side) of the photographic paper P cut to a print size or the like by pinching from both sides in the conveyance direction.

The density measuring unit 80 is disposed on the downstream side of the drying unit 60 and measures (colorimetry) the density of each band of the setup test print TP. The concentration measuring unit 80 will be described in detail later.
(Configuration of drying unit 60)
The drying unit 60 is provided with a device for blowing out warm air such as a blower (not shown), and dries the photographic paper P that has been subjected to development processing while transporting it. 3 and FIG. 4, the drying unit 60 includes a pressure-contact conveyance roller pair 61, a turn roller pair 62, a conveyance switching guide 63, a carry-out roller pair 64, and a turn guide 66 (conveyed as described above).

The pair of turn rollers 62 is a group of rollers for changing the transport direction so that the photographic paper P transported upward from the upstream side is transported downward, for example, a drive roller and a plurality of driven rollers. It consists of and.

The conveyance switching guide 63 is disposed immediately downstream of the turn roller pair 62. If the photographic paper P being conveyed is a normal print, as shown by the solid line in FIGS. 3 and 4, if the photographic paper P is a conveyance path a, and if it is a setup test print TP, then in FIG. 3 and FIG. As shown by the broken line, the printing paper P is switched to be conveyed to the conveyance path b.
The carry-out roller pair 64 is a roller for discharging the normal printing photographic paper P guided by the conveyance switching guide 63 to the conveyor 56, and rotates the driving roller by sandwiching the photographic paper P between the two rollers. Then, the photographic paper P is carried out. The photographic paper P passes through the carry-out hole 65 and is dropped and conveyed to the conveyor 56.

The turn guide 66 is a guide for guiding the printing paper P of the setup test print TP guided by the conveyance switching guide 63 to the density measuring unit 80. The photographic printing paper P sent out from the turn roller pair 62 and conveyed from vertically above is for changing the conveying direction to a substantially horizontal direction.
The shutter 67 is a blocking unit for preventing high-temperature dry air sent from a blower (not shown) in the drying unit 60 from being ejected from the carry-out hole (discharge unit) 68 toward the concentration measuring unit 80. As shown in FIGS. 3 and 4, the shutter 67 is installed in the vicinity of the carry-out hole 68 in the drying unit 60. When the photographic paper P is conveyed along the conveyance path b, the shutter 67 is pushed upward by the stencil of the conveyed photographic paper P (see FIG. 3) and is connected to the carry-out hole 68. The drying unit 60 is opened by the thickness of P. When the rear end of the photographic paper P passes through the shutter 67, the shutter 67 returns to the original position from the state where it is pushed upward (see FIG. 4), and blocks and seals the drying air from the drying unit 60. Thus, the photographic paper P sent out to the transport path b by the transport switching guide 63 passes through the carry-out hole 68 and is continuously sent out to the density measuring unit 80.

(Concentration measuring unit 80)
The density measuring unit 80 measures the density of each band while feeding the set-up test print TP conveyed. As shown in FIGS. 3 and 4, the concentration measuring unit 80 includes a housing 81, a concentration meter 82, and conveying rollers 83 and 83. The setup test print TP measured by the density measuring unit 80 will be described in detail later.

The densitometer 82 includes, for example, a filter such as a Latin filter (registered trademark) designed to have transmission characteristics with respect to light of a specific wavelength, and a CCD. Thus, the density of each band of the setup test print TP as shown in FIG. 5 is measured, and the measurement result is transmitted to the computer unit 30.

  The transport roller 83 transports the density meter 82 while feeding the frames so that the density of each band of the setup test print TP can be measured. Specifically, first, the center of the band F1 of the setup test print TP shown in FIG. 5 is conveyed to a position directly below the densitometer. When the densitometer 82 finishes measuring the density of the band F1, the conveyance roller 83 conveys the setup test print TP in the conveyance direction by a distance corresponding to the band width. By the transport roller 83 repeating this operation, the densitometer 82 can sequentially measure the respective densities from the belt bodies F1 to F22 in the setup test print TP.

The test print TP for setup which has finished measuring the density of all the strips F <b> 1 to F <b> 22 by the densitometer 82 is transported to the discharge unit 84 by the transport roller 83.
<Automatic setup with photo print system 1>
The photographic print system 1 measures the density (density pattern) of each band in the setup test print TP printed for setup at the start of every day operation with a densitometer 82 mounted on the density measuring unit 80. Then, the computer unit 30 performs a setup for adjusting the output state of the print exposure unit 54 based on the measurement result of the densitometer 82.

  Usually, the print quality (print density) output from the print unit 50 varies depending on the light emission state of the light source of the print exposure unit 54 and the state of each processing solution (processing solution temperature, oxidation state, degree of activation, etc.). End up. For this reason, the density of each of the plurality of strips having different densities formed on the setup test print TP is measured by the densitometer 82, and the adjustment of the output state of the print exposure unit 54 based on the measurement result, so-called setup is performed. Do. By performing such a setup, a highly reproducible photo print can be performed regardless of the state of the print exposure unit 54. Note that, in general, setup refers to adjustment of a cause related to the print exposure unit 54 among the above-described causes that influence the print state.

  In the setup in the photo print system 1 of the present embodiment, when the setup mode is selected by the GUI displayed on the monitor 21, a series of setups is automatically performed. Specifically, the computer unit 30 controls the print exposure unit 54 so that the test print TP for setup is output from the print unit 50 in the current state based on predetermined image data. The contents of the image data of the setup test print TP at this time will be described in detail later. The set-up test print TP exposed and developed by the print exposure unit 54 is automatically measured for the density of each band by the densitometer 82 constituting the density measuring unit 80. Further, a density difference between the measurement result and a predetermined reference density is calculated, and the output state of the print exposure unit 54 is adjusted based on the density difference. The print exposure unit 54 can be adjusted by, for example, a method of rewriting the LUT of image data provided in an exposure control device (not shown) of a laser exposure engine (an example of the print exposure unit 54).

<Test print TP for setup>
In the photographic print system 1 of the present embodiment, the test print TP for setup printed for setup and whose density of each band is measured is composed of band bodies F1 to F22 having 22 gradations as shown in FIG. Is formed.
[Features of Photo Print System 1]
(1)
In the photographic print system 1 according to the present embodiment, the density of the strips F1 to F22 formed on the setup test print TP is set on the part of the carry-out hole 68 of the drying unit 60 that dries the developed setup test print TP. In this system, a concentration measuring unit 80 for measurement is arranged close to each other, and a shutter 67 is provided in the drying unit 60 in the vicinity of the carry-out hole 68 on the drying processing side.

  Normally, when the printing paper P of the test print TP for setup is discharged toward the density measuring unit 80, the density measuring unit 80 is exposed to high-temperature drying air from the inside of the drying unit 60 ejected from the carry-out hole 68. . The density measuring unit 80 includes a filter and a CCD used for measurement, but these performances are easily affected by heat. Therefore, due to the heat of the drying air, the measurement accuracy of the density difference between the 22 gradation bands F1 to F22 formed on the setup test print TP, which requires high accuracy, is greatly reduced. As a result, the processing conditions are not properly corrected.

Therefore, in the photographic print system 1 of the present embodiment, a shutter 67 is provided in the vicinity of the carry-out hole 68 of the setup test print TP in the drying unit 60.
This minimizes the blowing of drying air from the drying unit 60 to the density measuring unit 80, so that the density measuring unit 80 is exposed to the drying air on the photographic paper P of the setup test print TP. It is possible to prevent the measurement accuracy from deteriorating with respect to the concentration of each band formed. As a result, even in the configuration in which the concentration measuring unit 80 is arranged close to the downstream side of the drying unit 60, the concentration of each band F1 to F22 included in the setup test print TP is accurately measured, and the setup operation is performed. It is possible to prevent a decrease in accuracy.

[Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.
(A)
In the above-described embodiment, the photographic print system 1 has been described with an example of a configuration in which the shutter 67 that opens and closes by the stencil of the photographic paper P is provided near the carry-out hole 68 on the drying unit 60 side. However, the present invention is not limited to this.

For example, as shown in FIG. 6, the housing of the drying unit 60 may have a configuration in which a heat insulating material (heat blocking unit) 59 is provided on the wall surface on the concentration measuring unit 80 side.
With this configuration, it is possible to suppress the propagation of heat due to the drying air from the inside of the drying unit 60 to the concentration measuring unit 80, and thus it is possible to suppress the variation in the measurement result with respect to the concentration of each band due to high heat. As a result, it is possible to prevent a reduction in accuracy of the setup work.

Moreover, you may use combining the shutter 67 demonstrated in the said embodiment, and the heat insulating material shown in FIG. In this case, it is possible to more effectively reduce the influence of heat on the concentration measuring unit arranged immediately downstream of the drying unit, and to perform highly accurate concentration measurement.
(B)
In the above embodiment, in the photo print system 1, an example of a configuration in which the shutter 67 is opened and closed by being pushed up using a stencil of the photographic paper P has been described. However, the form of the shutter 67 is not limited to this.

For example, the shutter 67 may be a goodwill type.
Normally, it is necessary to assume that the photographic paper P has various materials and thicknesses. For this reason, the photographic paper P may be weak. Even in such a case, the photographic paper P must be configured so that the shutter 67 can be surely pushed out so that the passage thickness of the photographic paper P can be secured.

Thus, by making the shutter 67 a goodwill type, the load required to push the shutter 67 is reduced, and the shutter 67 can be optimally opened and closed even with a weak photographic paper P. And the dry wind sprayed with respect to the density | concentration measurement part 80 from the drying part 60 can also be prevented. As a result, it is possible to prevent a reduction in accuracy of the setup work.
(C)
In the above-described embodiment and the above-described (B), an example of a configuration in which the shutter 67 is opened and closed by being pushed up using a stencil of the photographic paper P in the photo print system 1 has been described. However, the form of the shutter 67 is not limited to this.

For example, the shutter 67 may be opened and closed by automatic control. In this case, any system may be used as long as the sensor senses that the leading edge of the photographic paper P reaches the shutter 67 and opens and closes the shutter 67 based on the information.
This also prevents the drying air blown from the drying unit 60 to the concentration measuring unit 80. As a result, it is possible to prevent a reduction in accuracy of the setup work.

(D)
In the above-described embodiment, an example of a configuration in which dry air is blocked using the shutter 67 in the photo print system 1 has been described. However, the configuration for blocking the drying air is not limited to this.
For example, instead of the shutter 67, as shown in FIG. 7, an opening / closing part (door 69) is directly provided in the transport hole 68, and the door 69 is opened / closed to suppress the ejection of the drying part from the drying part 60. There may be.

  In this case, in order to open and close the door 69, for example, the roller pair 70 is installed in contact with the door 69 in the vicinity of the transport hole 68 on the drying unit 60 side. When the photographic paper P is conveyed, the roller pair 70 rotates in the direction of the arrow in the drawing to open the door 69, and when the rear end of the photographic paper P passes through the door 69, it rotates in the reverse direction to close the door 69. . By providing the roller pair 70, the door 69 can be opened and closed more smoothly.

Also with this configuration, it is possible to block the dry air blown from the inside of the drying unit 60 to the concentration measuring unit 80, so that fluctuations in measurement results due to high heat can be suppressed. As a result, it is possible to prevent a reduction in accuracy of the setup work.
(E)
In the above embodiment and the above (B) to (D), various types of shutters 67 have been described, and in the above (A), the heat insulating material 59 has been described as an example. Although the shutter 67 and the heat insulating material 59 are described as being installed separately, the present invention is not limited to this.

For example, you may install both the said embodiment, said (B)-(D), and the heat insulating material 59 together.
Accordingly, the heat from the housing can be simultaneously cut off together with the dry air, so that the dry air from the drying unit 60 can be more reliably prevented and the propagation of heat can be prevented. As a result, it is possible to perform highly accurate concentration measurement, and it is possible to prevent a reduction in accuracy of the setup work.

  The present invention has an effect of preventing drying air from the drying unit and, as a result, preventing a reduction in accuracy of the setup operation, and thus widely applied to a photographic processing apparatus, an image forming apparatus, a printing apparatus, and the like equipped with the drying unit. Is possible.
