Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic printing apparatus, a photographic processing method, and a photographic processing apparatus for printing an image frame on a developed short film on a web-like photosensitive material and then sending the same to a developing machine.

[0002]

2. Description of the Related Art Conventionally, a developed short film is supplied to a photographic printing apparatus, and an image frame on the developed short film in an exposure section of the photographic printing apparatus is printed on a photographic paper or the like. From the negative sheet containing multiple developed short films, take out only the developed short films that contain image frames that need to be printed, for example, because a printing order was placed.
Only the developed short film taken out was passed through the exposure section. After the exposure, the developed short film was returned to the original bag.

[0003] To remove the developed short film from the negative sheet, the end of the developed short film is manually pulled out of the negative sheet, and the leading end protruding from the negative sheet is fed by a machine. The short film was already taken out.

Conventionally, when the photosensitive material to be printed is in the form of a web, there is a difference between the transport speed in the photographic printing device and the transport speed in the developing device. Therefore, an accumulation mechanism is provided between the photographic printing device and the developing device. A structure is provided in which excess photosensitive material is accumulated between the photographic printing apparatus and the developing machine, thereby maintaining transport consistency.

[0005]

However, in the conventional technique of taking out only a developed short film of an image frame requiring printing, a conventional developing technique having an image frame requiring printing from a negative sheet accommodating a plurality of developed short films. Since only the used short film is taken out, in order to return the taken-out developed short film to the original position of the original negative sheet, it is necessary to perform a manual operation or move the taken-out developed short film to the original position of the original negative sheet. A device that requires complicated control such as returning is required.

[0006] As a method for solving the problem caused by taking out only the developed short film of the image frame requiring printing, all the developed short films of one order, that is, all of the inserted short films are used. Of the developed short film from the negative sheet, and passing all the developed short films taken out through a photographic printing apparatus (preferably, an exposure section of the photographic printing apparatus).

However, when all of the developed short films of one order contained in the negative sheet are taken out of the negative sheet and all the taken out short films are passed through a photographic printing apparatus, a certain printing order of the image frame is required. From printing on a photosensitive material to printing of the next image frame ordered on the photosensitive material may take a long time. When the photographic photosensitive material for printing is in the form of a web, the amount of the photosensitive material accumulated between the photographic printing apparatus and the developing machine, that is, the amount of accumulation, is increased because the web-like photosensitive material is transported to the developing machine during that time. It decreases, and the amount of accumulation finally becomes zero.

When the accumulation amount becomes zero, even the unexposed photosensitive material is sent to the developing machine, where the photosensitive material is subjected to the developing process, so that there is a problem that the photosensitive material is wasted.

Further, in order to eliminate such waste, if a reverse mechanism is provided for returning the unexposed photosensitive material once passed through the exposure unit to the exposure unit again at the time of exposure, and performing exposure.
There is a problem that the device becomes complicated and large.

[0010] Further, when the accumulation amount is zero due to the transport of the web-like photosensitive material by the developing machine, the photosensitive material is transported and moved even at the time of exposure in the printing apparatus, so that proper exposure can be performed. There is a problem that there is no.

Therefore, the present invention is intended to simplify the work of taking out a developed short film from a negative sheet, returning it to a negative sheet after exposure, when printing an image frame on the developed short film ordered for printing on a web-like photosensitive material. Operations can be performed with a simple device, and even if it takes a long time between printing one image frame on the photosensitive material and printing the next image frame on the photosensitive material, the device can be complicated. It is an object of the present invention to provide a photographic printing apparatus, a photographic processing apparatus, and a photographic processing method that can prevent waste of a photosensitive material and can perform an appropriate exposure without making the photosensitive material unnecessary.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, specific examples of the present invention will be described as embodiments, but the present invention is not limited thereto. Further, in the embodiments, although there are definite expressions for terms and the like, they show preferred examples of the present invention, and do not limit the meaning or technical scope of the terms of the present invention.

FIG. 1 is a schematic diagram showing a photographic processing apparatus having a photographic printing apparatus 100 and a developing machine 200 according to the present invention.

An example of an embodiment of the present invention will be described with reference to FIG. First, the operation of the exposure unit 50 of the photographic printing apparatus 100 will be described. The exposure unit 50 includes a light source 51,
Color filter 52B, shutter 52A, diffuser 5
3. Negative carrier 54, imaging lens 55, reflection mirror 5
And a paper mask 56 and the like. Light emitted from the light source 51 travels along the optical axis Z, is mixed and scattered in the diffuser 53, and becomes uniform scattered light. The developed short film 91 set on the negative carrier 54 is almost uniformly illuminated by the scattered light from the diffuser 53. In this embodiment, the developed short film 91 passed through the negative carrier 54 of the exposure unit 50 is all of the developed short film 91 of one order taken out from the negative sheet. Then, printing is performed on the web-shaped photographic paper 96 only for image frames that need to be printed because a printing order has been received. Further, the negative carrier 54 of the exposure unit 50
The developed short film 91 having no image frame requiring printing is passed through. The exposure unit 50 gives, for each image frame, whether or not the image frame of the developed short film 91 sent to the negative carrier 54 is an image frame that needs to be printed due to a printing order or the like. It is preferable to make the determination based on the frame number code.

In the photographic printing apparatus, a bypass branch point is provided in front of the exposure section, through which all the developed short films of one order taken out of the negative sheet are passed, and image frames requiring printing at the bypass branch point are provided. The developed short film having the image frame required to be printed is separated from the developed short film having no image frame, only the developed short film having the image frame requiring the printing is passed through the exposure unit, and after exposure, the printing is required. A developed short film having a proper image frame and a developed short film having no image frame requiring printing may be mixed.

Between the light source 51 and the diffuser 53,
A color filter 52B for each of yellow, magenta, and cyan and a shutter 52A are provided. These color filters are controlled and driven by a filter driving unit (not shown), and are inserted into and retracted from the optical path accordingly. Yellow, magenta, and cyan color filters 52
When B is inserted into the optical path, each color light of blue, green, and red is cut, and the exposure amount given to each color photosensitive layer of the web-shaped photographic paper 96 is appropriately adjusted. On the other hand, shutter 5
2A is controlled and driven by a shutter drive unit (not shown), and opens and closes the exposure light path accordingly. Thus, the exposure time is adjusted, and the exposure amount is adjusted.

Then, the web-shaped photographic paper 96 sent on the transport path is regulated on the outer edge by the paper mask 56 and waits on the print stage 57 for main exposure. Then, the illuminated original image on the developed short film 91 is projected onto the web-like photographic paper 96 by the imaging lens 55 and the reflection mirror 5, whereby main exposure, that is, imagewise exposure is performed. Incidentally, a zoom lens is used as the imaging lens 55, and the enlargement magnification is adjusted.

In this way, in the exposure section 50 of the photographic printing apparatus 100, the light source 51, the imaging lens 55, the color filter 52B and the shutter 52A are operated, and the main exposure is completed. The web-shaped photographic paper 96 on which the main exposure has been performed is immediately conveyed to the developing machine 200.

The web-shaped photographic paper 96 is made of the original rolled magazine 8.
The web-shaped photographic paper 96 is supplied by setting the original wound magazine 8 in the photoprinting apparatus 100. Also, the web-like photographic paper 96
Is provided with a punched hole indicating a cutting position by the hole punch 14 before exposure. The exposure is performed such that the portion provided with the punched hole becomes a non-image portion, that is, the portion provided with the punched hole is not included in the image portion. Alternatively, a punched hole may be formed in the non-image portion of the web-shaped photographic paper 96 after exposure by the hole punch 14. Further, as a means for indicating the cuttable position, a cut mark may be provided by printing on the exposed surface or the non-exposed surface instead of the punched hole.

The image frames to be printed are not limited to the image frames for which the printing order has been received. Further, the photographic light-sensitive material to be printed is not limited to web-like photographic paper.

Then, in the developing machine 200, the web-shaped photographic paper 96 is developed with a developing solution while being transported in the developing tank 71. Subsequently, it undergoes bleach-fixing processing in the bleach-fixing tank 72, water-washing processing in the first washing tank 73, the second washing tank 74, and the third washing tank 75, and is dried by the dryer 77 in the drying unit 76 and cut by the print cutter 7. Is done. The web-shaped photographic paper 96 that has been subjected to these series of processes becomes a print 97 and is discharged from the developing machine 200.

Incidentally, there is a difference between the transport speed of the web printing paper 96 in the photographic printing apparatus 100 and the transport speed of the web printing paper 96 in the developing device 200. For example,
If the transport speed in the photographic printing apparatus 100 is higher than the transport speed in the developing device 200, the web-shaped photographic paper 96 is accumulated between the photographic printing device 100 and the developing device 200 one after another.

Therefore, the photographic printing apparatus 100 and the developing machine 20
0, the web-like photographic paper 96 generated by the difference between the transport speed of the web-like photographic paper 96 in the photographic printing apparatus 100 and the transport speed of the web-like photographic paper 96 in the developing machine 200.
Accum 6 as a part to store the excess pool of
Is provided. The accumulation 6 makes it possible to supplement the difference in the transport speed between the photographic printing apparatus 100 and the developing device 200, and to maintain the transport consistency.

However, as in the present embodiment, the developed short film 91 passed through the negative carrier 54 of the exposure unit 50 of the photographic printing apparatus 100 includes all of the developed short films of one order taken out of the negative sheet. In the case where only the image frames which need to be printed are printed on the web-shaped photographic paper 96, another problem arises.

For example, an image frame that needs to be printed on the developed short film 91 is one of the image frames of one order.
In order to pass the developed short film 91 which does not include the image frame requiring printing to the negative carrier 54, the image frame requiring printing is printed on the web-shaped photographic paper 96. It may take a long time between printing and printing of an image frame requiring the next printing on the web-shaped photographic paper 96. During that time, the web-shaped photographic paper 96 is not transported in the photoprinting apparatus 100,
Since the web-shaped photographic paper 96 is conveyed only in the developing machine 200, the amount of the accumulation 6 is gradually reduced. Then, when the accumulation 6 finally disappears, the web-shaped photographic paper 9
6 is always pulled toward the developing machine 200,
It becomes difficult to stop and expose the web-shaped photographic paper 96 in the photoprinting apparatus 100, and even the unexposed web-shaped photographic paper 96 is transported to the developing machine 200,
It will be developed.

Therefore, the accumulation amount detecting means 7A, 7
B, 7C and 7D are provided, and the accumulation amount detecting means 7 determines that the accumulation amount has become equal to or less than the minimum amount defined by the predetermined amount.
When A and 7B are detected, the web 4 is cut by the cutter 4.

It is preferable that the predetermined amount defining the minimum accumulation amount is 1.2 to 2.0 times the linear distance between the cutter 4 and the pinch roller 16 as the minimum accumulation amount. Further, as another definition method, a preferable example is that the minimum accumulation amount is set to 1/3 to 1/10 of the maximum accumulation amount. And it is more preferably 1/4 to 1/8 of the maximum accumulation amount.

The above description is based on the premise that the transport speed in the photographic printing apparatus at the normal transport speed is faster than the transport speed in the developing machine, and all the short-length developed films of one order pass through the exposure unit. The problem that may occur in the case described above is described, but the invention is not limited thereto.At a normal transport speed, the transport speed in the photographic printing device is the same as the transport speed in the developing machine, or the transport speed in the photographic printing device is the developing speed. Even if the device is slower than the transport speed of the machine, to solve the problem that can occur when all the short films of one order pass through the exposure unit, the web The present invention of cutting photographic paper can be used.

The accumulation amount detecting means 7A and 7B detect the minimum accumulation amount, and the accumulation amount detecting means 7C and 7D detect the maximum accumulation amount. The accumulation amount detecting means 7A, 7C has an infrared irradiating unit for irradiating infrared light, and the accumulation amount detecting means 7B, 7D has an infrared light receiving unit for receiving infrared light. When the accumulation amount detecting means 7B detects infrared rays, it detects that the accumulation amount is less than the minimum amount, and cuts the web-shaped photographic paper 96 with the cutter 4. When the accumulation amount detecting means 7D does not detect the infrared ray, it detects that the accumulation amount is equal to or more than the maximum amount, and stops the exposure and conveyance of the web-shaped photographic paper 96 in the exposure section 50. Then, when the accumulation amount detecting means 7D detects infrared rays again, the exposure and conveyance of the web-shaped photographic paper in the exposure unit 50 is started.

Incidentally, the accumulation amount detecting means is not limited to the means using infrared rays. FIG. 2 is a schematic diagram of another example of the accumulation amount detecting means.

The accumulation amount detecting means comprises a weight 12A and a tension detecting means 12B. Usually Figure 2
FIG. 2B shows the state shown in FIG. 2B as the amount of accumulation 6 decreases. And weight 1
When the tension detecting means 12B detects a decrease in the tension due to the touch of the accumulator 6 with the accumulator 6, the web-shaped photographic paper 96 is cut by the cutter 4 by detecting that the amount of accumulator has become equal to or less than the minimum value.

Further, instead of the tension detecting means, means such as a spring scale is used so that not only the maximum and minimum values of the accumulation amount but also the accumulation amount can be appropriately detected by the weight detected by the spring scale. Is also good. In addition, a detection means made of a flexible rod-shaped member is provided at the lower part of the accumulator, and while the rod-shaped member detects a load by touching the rod-shaped member with the accumulator, it is detected that the amount of accumulation is greater than or equal to the minimum amount, When the member no longer detects the load, it detects that the amount of accumulation has fallen below the minimum amount,
The web-shaped photographic paper may be cut by a cutter.

Further, the cutting position for cutting the web-shaped photographic paper is preferably a non-image portion, and more preferably a cutting position where waste of the web-shaped photographic paper can be minimized.

Preferably, the cutting operation is automatically performed from the detection of a cut mark provided by printing or the like on a non-image portion of the web-shaped photographic paper or a punch hole provided by a hole punch or the like. In the present embodiment, a punch hole is provided by the hole punch 14 in a non-image portion, which is a position where the web-shaped photographic paper 96 can be cut, and the web-shaped photographic paper 9 is cut.
6, the position of the punched hole is detected by the punched hole detecting means 15 in front of the cutter 4, and the cuttable position of the web-shaped photographic paper 96 indicated by the detected punched hole is cut by the cutter 4. Then, the cutting operation is performed. The position where the cutting operation is performed, that is, the position of the cutter 4 is preferably between the exposure unit 50 and the developing tank 71.
It is more preferable that the temperature is shorter than the time before immersing in 1 in the developer.

In the present embodiment, the punch hole detecting means 15 is provided with an infrared light emitting portion and an infrared light receiving portion with a web-shaped photographic paper conveying path interposed therebetween. The punch hole is detected by the infrared light receiving unit receiving infrared light emitted from the infrared light emitting unit and passing through the punch hole. In addition, a mechanical means such as a microswitch may be used as a punch hole detecting means.

FIG. 3 is an explanatory view showing a preferred cutting position of the web-shaped photographic paper.

The cutting position of the web-shaped photographic paper 96 when the accumulation amount becomes equal to or less than the predetermined amount is determined by the image portions A1 and A2.
(Because it is a latent image because it is before development, it is indicated by a dotted line). A straight line C on the punched hole 13 which is a substantially rear end of the image portion A1 exposed last and indicates a non-image portion is set as a cutting position. This is preferable in that the unexposed web-like photographic paper 96 sent to the developing machine 200 can be reduced as much as possible.

Next, an example of a system using a photographic processing apparatus including a photographic printing apparatus and a developing machine according to the present embodiment will be described.

FIG. 4 is an overall schematic diagram of the system of this embodiment. The photographic processing apparatus including the photographic printing apparatus 100 and the developing machine 200 is partially omitted or changed in FIG. 4 except for the parts necessary for the description, but the photographic processing apparatus including the photographic printing apparatus and the developing machine illustrated in FIG. Same as the processing device.

The system according to the present embodiment takes out all the developed short films accommodated in the negative sheets from the negative sheets, supplies all of the developed short films taken out to the photographic printing apparatus, and supplies the photographic printing apparatus with an exposure section. This is a system in which image frames on a developed short film are printed on a web-like photographic paper, and the developed short film is stored in a new negative sheet.

A negative sheet 92 containing a plurality of developed short films 91 is placed on the negative sheet conveying table 11, and the judgment section 2 serving as a judgment means determines the developed sheets contained in the negative sheet 92 containing the developed short films 91. It is determined whether all the short films are developed short films that can be taken out. That is, the electronic camera 3 photographs the negative sheet 92 containing the developed short film 91, analyzes the shapes of the front end and the rear end of the developed short film 91 from the photographed image, and determines whether the shape is within the range of the normal shape. Whether or not the developed short film 91 contained in the negative sheet 92 is a developed short film that can be taken out is determined,
Further, the shape of the negative sheet is analyzed from the photographed image, and it is determined whether or not the shape is within the range of the normal shape.
All of the developed short films 91 contained in the developed short film can be taken out. Only when it is determined that the shape of the negative sheet is within the range of the normal shape, all of the developed short films can be taken out. It is judged that it is a developed short film. By judging these shapes, it is possible to exclude missing, bent, or cut objects.

Then, the negative sheet transport table 11 is transported to the next developed short film take-out section 10. Here, only when the determination unit 2 determines that all of the developed short films 91 contained in the negative sheet 92 are removable short films, the developed short film having the image frame ordered for printing. Whether or not
All of the developed short films 91 stored in the negative sheet 92 are taken out of the negative sheet 92. The developed short film that has been taken out is sent to the front / back determination correction device 30.
The negative sheet 92 from which all of the developed short films 91 have been taken out is conveyed in the direction of the arrow on each of the negative sheet conveyors 11 and sent to a negative sheet discharge unit (not shown). Then, the negative sheet 92 in which the developed short film 91 remains at the negative sheet discharge unit is exposed by manual operation.

The determination section 2 and the developed short film take-out section 10 constitute the developed short film take-out device 1.

Then, the developed short film 91 sent to the developed short film front / back determination correcting device 30 is inserted through the insertion port 34, and the developed short film front / back determination unit 31

According to the present invention described above, when an image frame on a developed short film ordered to be printed is printed on a web-like photosensitive material, the developed short film is taken out from the negative sheet, and is returned to the negative sheet after exposure. Work can be performed with simple work and devices. Further, even when the time from printing one image frame on the photosensitive material to printing the next image frame on the photosensitive material is long, it is possible to eliminate the waste of the photosensitive material without complicating the apparatus. Thus, it is possible to provide a photographic printing apparatus, a photographic processing apparatus, and a photographic processing method capable of performing appropriate exposure.
