BACKGROUND OF THE INVENTION
The present invention relates to a photographic printer that enables reverse conveyance of photographic paper using a motor for automatically loading and rewinding photographic paper.
[0002]
[Prior art]
The image data of each frame of the negative film read by the scanner is temporarily stored in the image memory, and this image data is read from the image memory and displayed on the liquid crystal panel. Techniques for exposing photographic paper are known.
[0003]
Using this image memory and LCD panel, each frame is arranged in a matrix and reduced and printed so that it is possible to easily search what kind of photograph is taken on one developed negative film. There are photographic printers that can make prints.
[0004]
In this photographic printer, a conventional main exposure unit for directly exposing an image recorded on a negative film to a photographic paper and a sub-exposure unit for exposing an image stored in an image memory to a photographic paper are They are arranged side by side along the paper conveyance path, and an index print is arranged on the photographic paper after every frame of the negative film.
[0005]
In addition, in this main exposure section, when a normal size print is exposed in the final frame because of the creation of various size prints, a gap is generated between the final frame and the index print, resulting in wasted paper. become.
[0006]
[Problems to be solved by the invention]
Therefore, when creating this index print, before the final frame is exposed, for example, two to three out of six exposures for creating one index print are performed in advance, and the final frame is printed. After that, the remaining part of the index print is exposed to eliminate waste of photographic paper.
[0007]
However, if the exposure of the index print is started after the last frame is exposed first, the processing of the negative film can be changed during the exposure of the index print. It leads to the ability improvement of.
[0008]
In other words, in order to improve processing performance and eliminate waste of photographic paper, it is very effective to first expose the last frame, then reversely transport the photographic paper, and then start index print exposure. it is conceivable that.
[0009]
However, installing a motor in the photographic printer to enable reverse transport requires that there is no space for installing the motor in the photographic printer and that a motor control board must be added. It was difficult for the reason.
[0010]

Further, an exposure lens 35 for changing the magnification of the index print image is disposed at a position adjacent to the liquid crystal panel 31. The liquid crystal panel 31 is provided with various types of light in the sub-exposure optical unit 22. A control unit (not shown) that monitors and controls the processing status is connected.
[0033]
As described above, the sub-exposure optical unit 22 reads the image data of each frame of the negative film 16 stored in the image memory 106, forms one index image data in which the frame images are arranged according to a predetermined rule, and forms It is possible to display on the liquid crystal panel 31 an image corresponding to image data of a predetermined number of frames of one index image data, for example, five frames (one column).
[0034]
Further, as shown in FIG. 3, at the position facing the main exposure optical system 46 in the exposure chamber 52, there is a main exposure unit 26 that exposes an image recorded on the negative film 16 onto the photographic paper 54. At a position facing the sub-exposure optical unit 22 in the chamber 52, there is a sub-exposure unit 28 that exposes the photographic paper 54 with an image stored in the image memory 106. That is, in the exposure chamber 52, the sub-exposure unit 28 and the main exposure unit 26 are arranged in order from the top, but the main exposure unit 26 creates a print of various sizes, so that the main exposure unit A gap S exists between the end of the normal size print 26 and the end of the sub-exposure 28.
[0035]
A main controller 20 that controls and monitors the entire printer processor 10 is installed below the exposure chamber 52. The main control unit 20 includes a CPU, RAM, ROM, input / output controller, and the like (not shown). The main control unit 20 is connected to the CC filter control unit 39, the negative density measuring device 56A, the image signal processing unit 102, and the control unit described above, and monitors and controls the operations of these components.
[0036]
On the other hand, as shown in FIGS. 1 and 3, a mounting portion 60 is provided at the corner of the upper surface of the casing 12, and the photographic paper 54 is wound around the reel 62 in layers in this mounting portion 60. A paper magazine 64 to be accommodated is mounted.
[0037]
Further, as shown in FIGS. 5 and 6, a motor 112 that is a drive source around which one end side of the endless belt 114 is wound is installed near the mounting portion 60, and the other end side of the endless belt 114. Further, a clutch 116 is arranged in which a driving force transmission path is switched by a solenoid (not shown).
[0038]
In other words, the first gear 118 and the second gear 120 are coaxially attached to the clutch 116, and either the first gear 118 or the second gear 120 is selectively driven by the operation of the solenoid. It can be rotated with a driving force of.
[0039]
On the other hand, the driven gear 124 is installed coaxially with the lower roller 32A so as to rotate integrally with the lower roller 32A on the lower side of the first conveying roller 32 including the upper roller 32B and the lower roller 32A. The driving force of the motor 112 is transmitted from the first gear 118 to the driven gear 124 via the intermediate gear 122.
[0040]
Therefore, when the clutch 116 is switched and the first gear 118 is rotated, the first conveying roller 32 is driven and rotated by the motor 112, and the photographic paper 54 is moved to the exposure units 26 and 28 side by the driving force of the motor 112. Is fed out from the paper magazine 64 side.
[0041]
Furthermore, the second gear 120 of the clutch 116 is engaged with a magazine gear 126 and a start gear 132A which is a gear on the start end side of the gear train 132. A driving force is transmitted to the reel 62 around which the photographic paper 54 is wound. The gear train 132 is configured by a plurality of gears including the start gear 132A meshing with each other.
[0042]
In the middle of the gear train 132, an electromagnetic clutch 134 that also serves as a gear is arranged. The electromagnetic clutch 134 is movable by a built-in solenoid between a position where the driving force is transmitted and a position where the driving force is not transmitted by moving in the axial direction (perpendicular to the paper surface). .
[0043]
Further, the gear train 132 is configured to rotate integrally with the lower roller 34A on the lower side of the second conveying roller 34 which is composed of the upper roller 34B and the lower roller 34A and guides the photographic paper 54 while sandwiching it. A terminal gear 132B, which is a gear on the terminal side, is installed coaxially with the lower roller 34A, and the second conveying roller 34 can be driven to rotate as the terminal gear 132B is rotated. .
[0044]
A one-way clutch 136 capable of transmitting driving force only in one direction is disposed in the lower roller 34A. For this reason, when the driving force is transmitted to the support shaft of the lower roller 34A in the clockwise direction, the outer peripheral surface of the lower roller 34A also rotates integrally, but in the counterclockwise direction, the driving force is not transmitted and is freely transmitted. Will rotate.
[0045]
That is, at the time of auto-loading in which the photographic paper 54 is sent out from the paper magazine 64, the gear train 132 is cut off by the electromagnetic clutch 134, and the second conveying roller 34 freely rotates to guide the photographic paper 54. Further, when necessary, such as during reverse conveyance for rewinding the photographic paper 54, the solenoids of the clutch 116 and the electromagnetic clutch 134 are simultaneously switched, and the driving force of the motor 112 is changed to the first via the second gear 120 and the gear train 132. As a result of being transmitted to the second transport roller 34, the second transport roller 34 is rotated by the motor 112 to transport the photographic paper 54 back to the first transport roller 32 side.
[0046]
As described above, as shown in FIG. 3, the first transport roller 32 is disposed in the vicinity of the mounting portion 60, and the photographic paper 54 is sandwiched and transported to the exposure chamber 52 in a horizontal state. Further, the photographic paper 54 is wound around the second conveyance roller 34 disposed between the first conveyance roller 32 and the exposure units 26 and 28, and the direction is changed by 90 degrees and drooped.
[0047]
A first stock unit 69 is provided between the first transport roller 32 and the second transport roller 34 to guide and stock the photographic paper 54 in a substantially U shape.
[0048]
Rollers 68A, 68B, 68C are disposed below the exposure units 26, 28 in the exposure chamber 52, and the photographic paper 54 on which the image of the negative film 16 is printed in the exposure chamber 52 is provided for each of the rollers 68A, 68B, 68C. The direction is changed by about 90 degrees each time and is conveyed to the processor unit 72 described later.
[0049]
Further, a friction belt 70 is rotatably installed at a position where the roller 68A and the photographic paper 54 are sandwiched, and the photographic paper 54 is sandwiched between the roller 68A and the friction belt 70 to reliably drive the roller 68A. Is transmitted.
[0050]
A cutter 71 is disposed on the downstream side of the roller 68A, and the cutter 71 cuts the rear end of the photographic paper 54 after the exposure processing. The photographic paper 54 cut in the cutter 71 and remaining in the exposure chamber 52 can be rewound onto the paper magazine 64 again.
[0051]
That is, when the photographic paper 54 is rewound onto the paper magazine 64, the motor 112 is driven and the clutch 116 is switched to the reel 62 in the paper magazine 64 via the second gear 120 and the magazine gear 126. The reel 62 rotates to transmit the driving force and wind up the photographic paper 54.
[0052]
At this time, since the clutch 116 is switched for the first conveying roller 32 and the one-way clutch 136 is disposed for the second conveying roller 34, the winding of the photographic paper 54 is hindered. There is nothing.
[0053]
Further, a second stock portion 73 is provided between the rollers 68A and 68B for guiding and stocking the photographic printing paper 54 that has been baked into a substantially U shape. In the second stock unit 73, the difference in processing time between the printer unit 58 and the processor unit 72 is absorbed by stocking the photographic paper 54.
[0054]
Next, the configuration of the processor unit 72 will be described.
As shown in FIG. 1, in the processor unit 72, a color development processing tank 74 in which a color development processing solution is stored, a bleach-fixing processing tank 76 in which a bleach-fixing processing solution is stored, and a plurality of washing processing solutions are stored. The rinsing processing tank 78 is provided, and the photographic printing paper 54 is sequentially conveyed through the color developing processing tank 74, the bleach-fixing processing tank 76, and the plurality of rinsing processing tanks 78, so that development, fixing, and water washing processes are sequentially performed. Done. The washed photographic paper 54 is conveyed to a drying unit 80 adjacent to the rinsing tank 78, where the photographic paper 54 is wound around a roller and exposed to high-temperature air to be dried.
[0055]
The photographic paper 54 is sandwiched between a pair of rollers (not shown), and is discharged from the drying unit 80 at a constant speed after the drying process is completed. A cutter unit 84 is provided on the downstream side of the drying unit 80, and the cutter unit 84 detects a cut mark applied to the photographic paper 54 and a density of the photographic paper 54. A paper density measuring unit 90 and a cutter 88 for cutting the photographic paper 54 are installed. The cut mark sensor 86, the paper density measuring unit 90, and the cutter 88 are connected to the main control unit 20, respectively. In the cutter unit 84, the photographic paper 54 is cut for each image frame by the cutter 88, and a photographic print is completed.
[0056]
The completed photographic prints are discharged to the sorter unit 92, sorted in the sorter unit 92, and subjected to a predetermined verification operation. After the defective print such as so-called defocusing is extracted by this verification operation, the normal photographic print is returned to the customer together with the negative film.
[0057]
Next, the operation of this embodiment will be described.
The printer processor 10 according to the present embodiment exposes an image stored in the main exposure unit 26 and the image memory 106 that exposes an image recorded on the negative film 16 onto a long photographic paper 54 sent out from the paper magazine 64. There is a sub-exposure section 28 for exposing the photographic paper 54.
[0058]
For this reason, the exposure process in the main exposure unit 26 of the printer processor 10 will be described first.
[0059]
With the black shutter 50 closed, the negative film 16 on which an image to be printed is recorded is set on the negative carrier 18, the light source 38 is turned on, and the image of the negative film 16 formed by the light transmitted through the negative film 16 is displayed. The density is measured by the negative density measuring unit 56. Based on the measured image density of the negative film 16, an appropriate exposure condition (for example, the insertion amount of each filter of the filter unit 40) is set by the main control unit 20. Next, the black shutter 50 is opened, and the image on the negative film 16 is exposed on the photographic paper 54 based on the set exposure condition.
[0060]
On the other hand, when the photographic paper 54 is not sent into the printer processor 10 prior to the exposure processing of the negative film 16 or when it is necessary to replenish the photographic paper 54, the photographic paper 54 is automatically loaded. .
[0061]
That is, as shown in FIG. 7, the first conveying roller 32 feeds the photographic paper 54 from the paper magazine 64 side to the exposure unit 26, 28 side by the driving force from the motor 112, and at this time, the first conveying roller 32 And the second conveying roller 34 disposed between the exposure units 26 and 28 guide the photographic printing paper 54.
[0062]
In the exposure of the negative film 16, the image of the negative film 16 formed by the light transmitted through the negative film 16 is sequentially read by the scanner 108. Then, the read image data is stored in the image memory 106 by the image signal processing unit 102.
[0063]
Further, when the exposure of one negative film 16 is completed and the index print is exposed on the photographic paper 54 as an exposure process in the sub-exposure unit 28, the sub-exposure optical unit 22 receives several frames from the image memory The image data is read out and exposed on the photographic paper 54.
[0064]
Then, by repeating this, the index print images to be printed are sequentially exposed on the photographic paper 54 as shown in FIG. 10, and finally all the frames of one image on the negative film 16 are photographic paper. 54 is exposed.
[0065]
When the exposure of each frame of the single negative film 16 is completed and the index print is exposed, the gap S is not formed on the photographic paper 54 as shown in FIG. As shown, the second conveying roller 34 is rotated by the motor 112 to reversely convey the photographic paper 54 so as to slightly return to the first conveying roller 32 side.
[0066]
Therefore, at the time of this reverse conveyance, the second conveyance roller 34 is driven by using the motor 112 for automatically loading and rewinding the photographic printing paper 54 by the first conveyance roller 32, and the second conveyance roller 34 Since the photographic printing paper 54 is reversely conveyed by the driving rotation, it is not necessary to newly provide the motor 112 for the reverse conveyance.
[0067]
This eliminates the need for a space for newly installing the motor 112 and eliminates the need to add a control board for the motor 112, thereby reducing the size and cost of the printer processor 10. . Accordingly, since the motor 112 is used as the drive source for the second transport roller 34, the control for driving the second transport roller 34 is facilitated.
[0068]
In the present embodiment, since the gear train 132 that transmits the driving force from the motor 112 to the second transport roller 34 is disposed between the motor 112 and the second transport roller 34, Even if the position is not changed, the driving force can be easily transmitted to the second transport roller 34, and the driving force can be reliably transmitted as compared with the case where the driving force is transmitted by a belt.
[0069]
Further, in the present embodiment, the electromagnetic clutch 134 is disposed in the gear train 132 so that the transmission of the driving force can be arbitrarily stopped. Therefore, the first conveying roller 32 feeds the photographic paper 54 to the paper. The electromagnetic clutch 134 can block transmission of rotation so that the gear train 132 does not become a load during auto-loading or the like sent from the magazine 64 side to the exposure units 26 and 28 side.
[0070]
If this electromagnetic clutch 134 is interlocked with the solenoid of the clutch 116, it is not necessary to add a substrate for the electromagnetic clutch 134 or change software.
[0071]
Next, processing in the processor unit 72 will be described.
As described above, after the image to be printed is exposed on the photographic paper 54, the photographic paper 54 sequentially conveys the color development processing tank 74, the bleach-fixing processing tank 76, and the plurality of rinse processing tanks 78 of the processor unit 72. As a result, the photographic paper 54 is sequentially subjected to development, fixing, and water washing. The photographic paper 54 that has been washed with water is conveyed to a drying unit 80 and dried by high-temperature air. The dried photographic paper 54 is conveyed to the cutter unit 84 and is cut for each image frame by the cutter 88 to be a photographic print. The photographic prints are discharged to the sorter unit 90 and sorted in the sorter unit 90.
[0072]
In the above embodiment, the light emitting diode is used as the index print exposure light source of the sub-exposure optical unit 22.
[0073]
On the other hand, in the above embodiment, an example in which the present invention is applied to a printer processor having a sub-exposure optical unit has been shown. However, a separate photo print system, an image memory, and image data stored in the image memory are displayed. The present invention can also be applied to a liquid crystal photographic printer having a liquid crystal panel to be exposed and an exposure system capable of exposing an image displayed on the liquid crystal panel.
[0074]
【The invention's effect】
As described above, the photographic printer according to the present invention has an excellent effect that the photosensitive material can be reversely conveyed by using a motor for automatically loading and rewinding the photosensitive material.
