DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic processing apparatus in which a film to which any one of polyethylene naphthalate (PEN), polyethylene terephthalate (PET) and triacetate (TAC) is applied as a support is mixed. .

[0002]

2. Description of the Related Art Generally, a photographic film (eg, a negative film) is a photosensitive emulsion in which fine crystals of silver halide such as silver chloride, silver iodide, and silver bromide and a photosensitive dye are mixed and dispersed in a gelatin solution. Is formed on the support by applying it very thinly and drying.

Conventionally, TAC (triacetate) is most frequently used as a support, and PET (polyethylene terephthalate) is sometimes used as the support.

[0004] Photographic films can be classified according to their use,
They are classified according to size, and can be classified into monochrome / color, negative / positive, and the like according to the application.

[0005] On the other hand, in the classification by size, films which are generally classified into roll films and sheet films, and which are wound and stored in a patrone in a roll shape, are the most popular films called "135". .

[0006] As described above, TAC is used as a base of a film to be wound into a roll, because TAC has no optical anisotropy and high transparency. Further, it has an excellent characteristic in the curl removability after the development processing. That is, since the TAC-based film has a relatively high water absorbency as a plastic film as a characteristic derived from its molecular structure, the curl caused by being wound up in a roll and aged over time causes the molecular chain to be absorbed by the water absorption in the development process. The molecular chains that have flowed and become immobilized over time undergo rearrangement, and as a result, curling is eliminated.

[0007] By the way, instead of TAC or PET currently used as the support, strength, dimensional stability,
A support excellent in thinning and the like has been developed and proposed (Japanese Patent Application No. 4-208637).

This support is called PEN (polyethylene naphthalate). In particular, by applying annealed (heat-treated) PEN as a support, the strength,
The dimensional stability is improved, and the thickness can be reduced.

[0009]

However, PEN
Since the properties of PEG and TAC are remarkably different from those of TAC and PET, it is preferable that the same photographic processing apparatus be applied to PEN.

For example, since PEN has a higher glass transition point than TAC or PET, it is necessary to change the temperature applied to the joint when joining films in a splicer which is a part of a photographic processing apparatus. .

When films of different bases are continuously (joined) by the splicer, the subsequent processing (development processing, printing processing, etc.) may be affected. For example, a change in drying conditions due to a difference in the type of the support in the developing unit, a change in the amount of light at the time of printing in a printer, the strength of a cutter in a cut inserter, etc.

In the case of a roll of a support having different physical property values,
Since the transfer conditions are different, the reliability of the transfer is reduced.

In view of the above facts, the present invention considers PEN, TA

In the large laboratory, first, the film splicer 1
At 00, the loaded films (contained in the patrone) are successively connected to form a long roll-shaped film. At this time, the information of the film is written on the LSI card.

The rolled film and the LSI card are then sent to the tester 102, where the state of bonding between the films is checked, and then sent to the developing machine 200. In the developing machine, the film is transported in a processing tank for development, fixing, washing and the like, and is dried to be visualized. This visualized film is conveyed to the printer 300 together with the LSI card in a state of being wound up in a roll shape.

In the printer 300, the image frames of the roll film are sequentially positioned at the printing position, and the transmission image is printed on the photographic paper with a predetermined exposure amount. By sequentially performing this, images are sequentially printed on the photographic paper.

The film after the printing process is sent to the cutting inserter 400 to be returned to the customer, cut at a predetermined number of frames (for example, every 6 frames), and placed in a translucent bag called a negative sheet. It is accommodated by this.

The configuration of each device will be described below. In the tester 102, since the operator only checks while moving the roll-shaped film from one side to the other side, the description of the configuration is omitted, and the film splicer 100, the developing device 200, the printer 300 and The description will be made in the order of the cutting inserter 400. (Film Splicer 100) FIG. 2 shows a film splicer 100 according to the present embodiment. On the main table 112 of the film splicer 100, a loading section 116 for loading the patrone 12 into the apparatus is provided. The input unit 116 is provided for the main table 11.
A cover 120 for closing the hole 118 is attached to a rectangular hole 118 provided in the apparatus 2.

The lid 120 is provided with a concave portion 126 so as to accommodate a part of the patrone 12, and an operator places the patrone 12 in correspondence with the concave portion 126.

The lid 120 has a structure in which the lid 120 is pivoted inward around the side of the apparatus. When the hole 118 is opened, the lid 120 becomes an inclined surface, and the cartridge 12 slides down into the contents of the apparatus. It has become.

[0034] Three magazines 154 are arranged in a high position on the far side of the main table 112 of the film splicer 100.

As shown in FIG. 3, each magazine 154 is provided with a reel 155, and the negative film 14 is wound in a roll.

When driving the negative film 66 (when moving the negative film 56 in the conveying path direction), a splice tape is attached to the negative film 14.

Here, by heating the joining head 166 to a predetermined temperature, the negative film 14 can be securely joined by the splice tape, but the optimum temperature varies depending on the type of the support. Therefore, the optimum temperature is stored for each type of the support, and the support identification unit 1
The temperature most suitable for the support of the negative film 14 identified by reference numeral 10 is read to control the temperature.

That is, PEN is superior in thermal dimensional stability to TAC. For this reason, in the case of the conventional negative film 14 using TAC, the temperature limit of the bonding head 166 is 170 ° C. to 190 ° C. However, PEN does not affect the dimensional stability even when the temperature is further increased (190 ° C. to 220 ° C.). Therefore, in the bonding of the negative film 14 of the PEN specification, the bonding is performed in a time (1 second) shorter than the time (1.5 seconds) required for bonding the negative film 14 of the TAC specification.

Further, corresponding to the joining head 166,
A negative film front end detection sensor 170 is provided below the transport path, and detects the front end of the negative film 14 sent out by a pair of rollers 164. The transport is stopped by the signal from the negative film leading edge detection sensor 170.

Next, the roller-shaped negative film 14 of the same support as the single negative film 14 at the standby position is pulled out of the magazine 54 by driving the rollers 178, 180 and 182, and sent to the joining position.

In the case where the support is the same as the roll-shaped negative film 14 bonded immediately before, there is no need to replace the roll-shaped negative film 14.

When the magazine is determined, the splice tape is sent to the joining head 166, the joining head 166 is driven, and the splice tape is attached to the single negative film 1.
4 and the roll-shaped negative film 14 are attached so as to be bridged therebetween, and the two are joined.

When the type of the support identified by the support identification unit 110 is TAC, the bonding temperature is set to 185.
° C and the bonding time are set to 1.5 seconds. In the case of PEN, the bonding temperature is set to 200 ° C and the bonding time is set to 1 second. PET is an intermediate value.

That is, the negative film 14 of the PEN specification
Since the temperature of the joining can be increased, the joining time can be shortened accordingly, and the working efficiency is improved.

Next, the winding of the negative film 14 into the magazine 154 corresponding to the bonded roll-shaped negative film 14 is started.

Here, the negative film rear end detection sensor 17

Set values such as the drying air temperature are determined.

That is, the negative film 14 of the PEN specification
Has many excellent points in physical properties as compared with the negative film 14 of TAC and PET specifications. For example, it has good temperature and humidity stability, is hard to curl, and has excellent dimensional stability. Also, there is little deformation at high temperatures. PEN is more resistant to strong alkali and strong acid liquids than PET, and hardly causes hydrolysis.

From the characteristics, the processing conditions for each support are determined as follows. Processing solution temperature: TAC <PET <PEN (high) Transfer speed: TAC <PET <PEN (fast) Drying temperature: TAC <PET <PEN (high) The conditions are optimized, and the reliability of transportation is increased, and at the same time, the processing time can be reduced. Also,
The information on the support may be read from an LSI card sent together with the roll film from the previous process, and the conditions may be automatically set.

The dark room processing unit 204 and the light room processing unit 206
Is divided into a plurality of tanks. Each tank stores a processing liquid, and is provided with a immersion processing rack 218 (see FIGS. 5 and 6) (FIG. 6 shows the dark room processing unit 204).

Has become. That is, it is possible to select an optimum cutter blade in terms of strength, durability and the like according to the type of the support of the negative film 14.

The cutting blades have different cutting shapes. For example, the shape after the cutting is changed according to the type of the support, such as a straight cut, a sinusoidal cut, or a triangular cut. Thus, by visually observing the shape after cutting, the type of the support of the negative film 14 can be determined, and the identification can be performed without using the identification unit at the time of reprinting. Become simple.
In addition, this cut shape is not limited at all. For example, as shown in FIG. 13, after being cut straight, a chamfer 474 is applied to a corner, or an R chamfer 476 is applied so as to be distinguished. Is also good.

The transport amount of the negative film 14 at one time is equivalent to six image frames.
Is shortened every 6 frames. The shortened negative film 14B is sent to the negative film sheet insertion portion 462.

A transparent glass plate 464 is disposed above the negative film 14 between the transport section 438 and the cutter section 456 to correct the slack in transporting the negative film 14 and to reliably move the negative film 14 to the cutter section 456. I'm guiding you. An opening (not shown) is provided below the negative film 14 corresponding to the glass plate 464 so that light from a light source is irradiated. This allows the light from the light source to pass through the image, and allows the operator to visually check the transmitted image.

The negative film sheet insertion portion 462 includes a delivery drum 468 provided on the upper side of the sub-table 416 and a take-up drum 470 provided on the side of the main table 412 on the near side. A negative film sheet 472 is wound around these drums 468 and 470. The negative film sheet 472 has a structure in which a plurality of protective bags 472A are continuously formed. The intermediate portion of the negative film sheet 472 is guided so as to be flush with the slope portion 414 of the sub-table 416, and the protective bag 47 located downstream of the cutter portion 456.
The short negative film 14B is inserted into 2A. Short negative film 14B is protective bag 472A
11, the delivery drum 468 and the take-up drum 470 rotate in the directions indicated by arrows B in FIG. 11, respectively, and the next protective bag 472A is positioned downstream of the cutter unit 456.
By operating this in conjunction with the cutting of the negative film 14 by the cutter unit 456, the short negative film 14
B are successively stored in the protective bag 472A.

By the way, PEN is superior to TAC in many points, but in terms of electrostatic trouble, the surface resistance is higher than TA.
It is disadvantageous because it is larger than C. For example, if static electricity is generated when inserting the negative film sheet 472,
It may not be able to insert smoothly. Therefore, in the pre-insertion step, if an area for removing static electricity (static elimination area) is provided, and the negatively charged film 14 is removed and then inserted into the negative film sheet 472, smooth insertion can be performed. Can be. In addition, if a negative sheet mixed with a conductive material or an antistatic agent is used, electrostatic trouble can be prevented. Furthermore, since PEN is yellowed by ultraviolet rays, if a negative sheet mixed with a UV agent is used, discoloration of a film using PEN as a support can be prevented.

Of the support of the negative film 14 by the passage of PE)
N, PET, TAC) can be identified.

The identification result is reflected on the transport speed of the negative film 14, the temperature of the processing solution, the temperature of the drying air, and the like (similar to the developing machine 200 of the large laboratory).

Particularly, at the drying temperature, TAC is usually 50 ° C.
６０60 ° C., whereas PET is 79 ° C., P
With EN, the temperature can be increased to 119 ° C.

Also, without changing the conditions, PEN, PET,
The processing may be performed only on the film having any one of the supports of TAC, and the film of the other supports may be rewound to the cartridge and discharged.

When the entire amount of the negative film 14 is pulled out, the rear end of the negative film 14 is released from the spool. A film transfer unit 542 is placed in each processing tank, and the reader 530 and the negative film 14

Is preferred.
As a result, generation of a stitch mark or the like can be prevented beforehand, and dust can be eliminated, thereby preventing the processing liquid from being stained. This static elimination is particularly effective for a negative film of PEN specification. This is because PEN has a high surface resistance and easily generates static electricity. (Printer Processor 600) FIGS.
Shown is a printer processor 600 with a photographic printer according to the present invention.

The printer processor 600 is provided with a work table 614 whose outside is covered with a casing 612 and which protrudes from the casing 612 on the left side of FIG.

As shown in FIG. 19, the work table 6
Below the 14, a light source unit 636 is arranged. The light source unit 636 includes a light source 638 therein, and the light source 638
From the filter unit 640 and the diffusion tube 64
1 through the negative carrier 618 on the work table 614
The negative film 14 is disposed at the printing position of the negative. The filter unit 640 includes C,
It is composed of three color filters of M and Y, and each filter can be made to appear on the optical axis of the light beam.

Above the work table 614, an arm 644 protrudes from the casing 612. Arm 6
An optical system 646 is provided in 44. Optical system 6
Reference numeral 46 denotes a lens 648 and a shutter 650 which are arranged on the optical axis of the light beam transmitted through the negative film 14. The light transmitted through the negative film 14 passes through the lens 648 and the shutter 650 of the optical system 646, and then passes through the exposure chamber 652.
The image recorded on the negative film 14 is formed on the photographic paper 16.

The optical system 646 includes a density measuring device 6 such as a CCD for measuring the density of an image recorded on the negative film 14.
56 are arranged. The light transmitted through the negative film 14 is reflected by a half mirror disposed near the shutter 650 and reaches the density measuring device 656. The measuring region is divided into a plurality of regions and transmitted through each region. By measuring the light quantity obtained, the average density of each area and the average density of the entire image can be obtained. In the printer processor 600, the density measuring device 656 is used.
An exposure correction value at the time of exposure is set based on data obtained from the average density of the image measured by the method and data input by a key by an operator. The image of the negative film 16 positioned at the printing position is the CC
The image is printed on a CRT (not shown) via D, and the image to be printed is visible to the operator. The light source section 636, the optical system 646, and the exposure chamber 652 form an exposure section 658 for performing a printing process.

On the upper surface of the work table 614, a negative carrier 618 on which the negative film 14 is set is mounted, and the negative film 14 is sandwiched and transported one image at a time. A so-called frame feed in which the frames are sequentially arranged in the printing opening is performed.

Here, a support identification section 620 is provided on the most upstream side in the negative film transport direction of the negative carrier 618, and the negative film 14 is provided with the support identification section 620.
, And is positioned to the printing opening 626.

The result of identification of the support by the support identification section 620 is reflected in the exposure amount. That is, in the present embodiment, the exposure amount reference value is determined for each support from the difference in the refractive index and the like of the support, and the exposure amount reference value is selectively selected based on the identification result in the support identification unit. It is supposed to be. Although not shown, it is preferable to provide an ultraviolet absorbing filter in any one of between the light source 638 and the negative carrier 618 as in the printer 300 of the large lab, and further, without changing the reference value of the exposure amount. A diffuser may be selected for each type of support and arranged on the optical axis (see FIG. 10).

FIG. 16 shows a negative carrier 6 according to this embodiment.
18 is shown. The negative carrier 618 includes a base 303 as a base and an opening / closing cover 304 as a lid.
The main part is configured.

On the base 303, a negative film transport path 305 is formed as a guide path.

In the negative film transport path 305, the negative film 14 has an arc shape in which the center in the width direction is slightly upwardly convex due to curling, and only the both ends of the negative film 14 in the width direction are on the surface of the transport path 303. Often comes in contact with.

Here, PEN, TAC, and PET have differences in the following characteristics. Difference in slipperiness (friction coefficient TAC <PET <PEN) Conventional conveyance path 3 having relatively low hardness due to difference in friction coefficient
On 05, the same transport force cannot be applied. Difference in hardness, difference in long curl condition (hardness TAC <
PET <PEN) The durability of the transport path 305 becomes a problem. If the film is curled in the longitudinal direction, the leading edge becomes
05 will be conveyed. Difference in refractive index (refractive index TAC <PET <PEN) Light piping (propagation of light within the film thickness) development in PEN may cause poor exposure during printing,
A decrease in the sensor detection rate may occur. Easiness of generating static electricity (surface resistivity TAC <PET,
PEN) Static electricity is generated by friction caused by high-speed conveyance. For this reason, dust easily adheres to the negative film 14, and there is a possibility that the dust may burn in during printing or the film itself may be damaged. Furthermore, malfunctions of various sensors may be induced by electrostatic noise.

Therefore, as shown in FIG. 17A, the contact surface (part of the side and bottom) of the transport path 305 with the negative film 14 is made of a hard member such as stainless steel which is relatively hard and slippery. 311 are attached. Thereby, even the negative film 14 of PEN specification having relatively high hardness and high friction coefficient can be stably passed. In addition, as shown in FIG. 17B, a substantially L-shaped hard member 315 in which the members of the side surface and the bottom surface are integrated may be provided.

An exposure opening 306 is provided at a central portion in the longitudinal direction of the negative film transport path 305, and serves as an irradiation port of a light beam from a light source 314 (see FIG. 9) provided in the printer processor 10.

The size of the exposure aperture 306 is substantially the same as the size of the image frame of the negative film 14. In the negative film transport path 305, transport rollers 308, 310, 312, and 313 correspond to the lower surface of the negative film 14 on the upstream side (left direction in FIG. 16) and on the downstream side (right direction in FIG. 16) of the exposure opening 306. It is arranged. The transport rollers 308, 310, 312, and 313 are driven in the same rotation direction at the same rotation speed.

The opening / closing cover 304 is supported by a bar 326 fixed to the pedestal 303 at the lower end of a housing-like cover main body 324, and can be opened and closed with respect to the pedestal 303 around the bar 326. ing.

A through hole 328 corresponding to the exposure opening 306 is provided at the bottom of the cover body 324.
In addition, the cover body 324 is provided with an upper guide base 330 at a position corresponding to the negative film transport path 305 in a closed state.
Is attached, and the negative film guide wall 332 is integrally formed, so that a gap is formed between the tip of the negative film guide wall 332 and the bottom surface of the negative film transport path 305. The gap dimension is slightly larger than the thickness dimension of the negative film 14 to secure a transport path at the end of the negative film width direction.

Further, the transport rollers 308, 310, 312 and 313 provided on the negative film transport 305 are provided.
In response to the above, the idle roller 3
34, 336, 338, and 339 are disposed, and when the open / close cover 304 is closed, the idle film 334, 336, 338, and 339 and the transport rollers 308, 310, 312, and 313 allow the negative film 1
4 to be able to transmit the conveying force. These idle rollers 334, 336, 33
8 and 339, the nip pressure of the negative film 14 depends on the type of the support of the negative film 14 (PEN, PET, TA).
C) can be changed.

Further, when the opening / closing cover 304 is closed, the negative film 14 comes into contact with the charge removing brush 333 to prevent static electricity from being generated. This is because the negative film 14 of the PEN specification has a higher surface resistivity than the negative film 14 of the TAC specification, and therefore, when conveyed at a high speed, static electricity is easily generated by the frictional force. Therefore, the charge is removed (discharged) by the discharge brush 333 to prevent static electricity.

The transport rollers 308, 310, 3
12, 313 or idle rollers 334, 336, 3
Both or one of 38 and 339 may be conductive rubber specifications, or a neutralizing agent or the like may be applied to the negative film 14 of PEN specifications.

At the center of the upper guide base 330 in the direction of transport of the negative film, an upper mask as a negative film holding means having an opening provided at a position corresponding to the through hole 328 and movable relative to the upper guide base 330. 340 is arranged and attached to the mask base 342.

At the base end of the mask base 342, a bracket 360 is formed. This bracket 360
The mask base 342 is urged in the opening direction by a torsion spring 364 while being pivotally supported by a bar 362 provided on the pedestal 303. On the other hand, an insertion groove 368 in which the plate-shaped support piece 366 of the upper mask 340 can be mounted is provided at the tip of the mask base 342. The mask base 342 is mounted on the pedestal 303 with the cover body 304 closed.
Corresponds to the solenoid 350 provided in the first embodiment. Therefore, when the solenoid 350 is energized, the mask base 342 is attracted by the magnetic force, and the torsion spring 36
The upper mask 340 is brought into close contact with the exposure opening 306 of the negative film transport path 305 against the urging force of No. 4 to sandwich the negative film 14 positioned on the optical axis.

As shown in FIG. 18, when the open / close cover 304 is closed, both ends in the width direction of the upper mask 340 are bent at substantially right angles so as to face both end surfaces in the width direction of the negative film 14. Is provided. The cover film 340A allows the negative film 14
Light entering from both end surfaces in the width direction is suppressed, and insufficient exposure and errors in exposure calculation and the like can be eliminated.

As described above, the above-mentioned problems can be solved by making the sliding surface during film conveyance a hard material, preventing light from entering from the film side edge and suppressing generation of static electricity. .

As shown in FIG. 19, a mounting section 660 is provided above an arm 644 provided with an exposure chamber 652. The mounting unit 660 transfers the printing paper 16 to the reel 6.

[Embodiment of Support Identification Unit Provided in Each Apparatus] The support identification unit 110 of the film splicer 100 and the developing machine 200
Of the printer 300, the support identification unit 372 of the printer 300, the negative film detection unit (support identification unit) 440 of the cutting synthesizer 400, the support identification unit 540 of the developing machine 500, and the support identification of the printer processor 600. The unit 620 (hereinafter collectively referred to as a support identification unit _SBASE ) has a function of determining the type of the support of the negative film 14 that passes therethrough. is there. When roughly classified, means for reading and determining information from the negative film 14;
There is a means for measuring the physical properties and the like of the negative film 14.

Further, in the film splicer 100, the developing machine 500 of the minilab, and the printer processor 600, information can be obtained from the cartridge 12.

Hereinafter, specific examples will be described. (First Embodiment "Reading Information from Negative Film")
FIG. 20 shows a support identification unit _{SBASE according} to the first embodiment. The support identification unit S _BASE does not determine the support of the negative film 14 as a single unit, but rather detects the symbol, mark, notch, or the like attached to the negative film 14 in advance. .

That is, as shown in FIGS. 21 (A) to 21 (C), the band-shaped mark 18 having a density higher than the base density after development so as to extend outside the image frame of the negative film 14 and over the perforation 14A. Is recorded. This band-shaped mark 18 is designed to be added at the stage of manufacturing the negative film 14. Therefore, as shown in FIGS. 21A to 21C, different marks are provided depending on the type of the support. It is easy to attach 18 (one band, two bands, discontinuous band).

On the other hand, the support discriminating portion S _BASE has two sensors 2 arranged with a light projecting portion and a light receiving portion so as to sandwich the negative film 14 along the passing position of the band-shaped mark 18.
0A and 20B are arranged. Therefore, when the negative film 14 of the mark 18 of one band passes, one sensor 20A continues to be in the ON state and the other sensor 20B
Will be kept off. In addition, when the negative film 14 of the mark 18 of the two bands passes, both the sensors 20A and 20B continue the ON or OFF state. Furthermore, when the negative film 14 of the mark 18 of the discontinuous band passes, one or both of the sensors 20A or 20B repeats ON / OFF.

By determining the output signal, the type of the support of the negative film 14 can be determined.

In the first embodiment, a band-like mark is formed on the perforation 14A. However, the mark shape may be the same and the color may be changed. Instead of the optical marks, the intervals of the perforations 14A themselves may be changed for each type of the support as shown in FIGS. 22 (A) to 22 (C). Further, as shown in FIGS. 23A to 23C, the identification holes 22 (or the optical marks of the optical marks) having different sizes (diameters), positions, and numbers are provided at the front end or the rear end of the negative film 14 for each support. (A cut-out at the end of the negative film) may be provided (number in FIG. 23). Further, as shown in FIG. 23, the identification notch 24 (or hole)
May be formed evenly in the width direction end of the negative film 14 in the longitudinal direction. Even if this is cut at every predetermined frame (piece negative), it is easier to determine the support.
Alternatively, a code for determining the type of the support of the negative film may be inserted in the latent image bar code on the negative film indicating the frame number or the DX code.

As a means for distinguishing the negative film 14 of the PEN specification from other specifications (PET, TAC), both end faces in the width direction of the negative film 14 may be painted black or the like. According to this, write piping unique to PEN can also be prevented, and the negative carrier 61 shown in FIG.
8, the cover portion 340A of the upper mask 340 becomes unnecessary.

Further, for any of the negative films 14 coated with a magnetic material, the presence or absence of magnetism or the type of film support may be determined by a magnetic detector using a recorded magnetic code. . (Second Example "Measurement of Physical Properties and the Like of Negative Film 14") FIG. 24 shows a support identifying section S according to the second example.
_BASE is shown. The support identification section S _BASE has a function of determining the type of the support even if a mark or the like corresponding to the type of the support is not attached to the negative film 14 in advance.

That is, in the second embodiment, the type of the support is determined based on the difference in the physical properties and the like of the negative film 14. Support identification unit S _BASE, the roller 26, 28 so as to sandwich the conveyance path of the negative film 14 is disposed. The lower roller 26 is fixed, and the upper roller is connected to the tracing stylus 30A. This measuring element 30A
It protrudes from the main body 30B of the displacement meter 30, and the amount of axial movement (movement in the direction of the arrow in FIG. 24) of the tracing stylus 30A is calculated as the amount of displacement from the reference position.

Here, the thickness of the negative film 14 of the PEN specification and the thickness of the negative film 14 of the TAC specification are different, and the relationship of PEN <TAC is satisfied. Therefore, when the measurement result of the displacement meter indicates that the thickness is small, it can be determined that the negative film 14 of the PEN specification has passed.

The following means can be cited as other means. First, the reference refractive index of the negative film to which each support is applied is measured and stored using a refractometer. The refractive index of the negative film 14 passing through the support identification unit S _BASE is measured and compared with the stored data. PE
Since N, TAC, and PET all have different refractive indices, the type of the support can be easily determined by comparing the measured refractive index with the stored refractive index.

Secondly, it is also possible to measure the absorption spectrum of infrared rays and determine the type of the support from the measured absorption wavelength.

Third, the dielectric constant is measured, and the type of the support can be determined from the measured dielectric constant.

Fourth, a simple puncher with a built-in pressure sensor can be used to make a hole in the non-image area at the leading or trailing end of the negative film, and the type of support can be determined based on the difference in breaking strength. It is. (Third Embodiment "Acquiring Information from Patrone 12") FIG.
5 shows a support identification unit _SBASE applicable to the film splicer 100 of the large laboratory, the developing machine 500 of the minilab, and the printer processor 600.

The support discriminating section S _BASE does not discriminate the support of the negative film 14 as a single unit, but detects the sign, mark, notch or the like attached to the patrone 12 in advance. ing.

That is, as shown in FIG. 26, a seal 32 having a bar code 34 is attached to a part of the outer periphery of the cartridge 12. The barcode 34 is attached in accordance with the type of the support of the negative film 14 stored in advance, and is, for example, posted to the film splicer 100 and set in a predetermined position. It is designed to face _BASE .

The support discriminating unit S _BASE is constituted by a bar code reader.
By reading the barcode 34 on the seal 32 attached to the negative film 14, the type of the support of the negative film 14 stored therein can be determined.

However, in the large lab, the film splicer 1
Thereafter, since the patrone 12 and the negative film 14 are separated from each other, the type of the support of the negative film 14 from the patrone 12 cannot be determined as described above.

On the other hand, in the minilab, since the processing is generally performed for each patrone (one negative film), information on the type of the support is obtained from the patrone 12 and the respective processing conditions are changed in the same manner as described above. It is possible.

In the third embodiment, the cartridge 12
27, a sticker 32 with a bar code 34 is attached to the outer periphery of the cartridge 12 as shown in FIG.
Of the end face to the number varies depending on the type of support, the size, the provided grooves 36 of shape, as a support identifying unit S _BASE, the groove 3
By arranging sensors for recognizing the number, size, and shape of 6, the type of the support can also be determined.

In the large lab, the negative film 14
Is pulled out from the patrone 12, if the rear end (non-image portion) is caught for some reason, the strength of the negative film 14 of the TAC specification is relatively small.
It can be separated from the patrone 12 by breaking. However, the negative film 14 of the PEN specification has high strength, does not break under normal tensile force, and may not be separated from the patrone 12. Therefore, as shown in FIG. 28, a predetermined amount of cut 38 is formed from both ends in the width direction, and the strength of this portion is reduced in advance. As a result, when the trailing end of the negative film 14 is caught by the cartridge 12 and the cartridge 12 or the negative film 14 cannot be separated in a normal state, a break occurs from the cut 38 and the negative film 14 can be extracted.

As shown in FIG. 29, perforations 40 may be provided to reduce the breaking strength.

[0160] Such cuts 38 or perforations 40 can also be used for discrimination between TAC and PEN.

[0161]

As described above, the photographic processing apparatus according to the present invention has an excellent effect that, when processing a film in which PEN, TAC, and PET supports are mixed, processing suitable for each of them can be performed. Having.
