DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic film processing apparatus which can be loaded with a cartridge for storing a photographic film having a support made of polyethylene naphthalate (A-PEN) heat-treated at high temperature on a spool.

[0002]

2. Description of the Related Art In recent years, it has been proposed that a developed negative film is wound up again into a cartridge and returned to a customer. In this case, by reversing the spool shaft accommodating the negative film, it is possible to easily perform so-called tongue-out. In the case of a request for additional printing or the like, this cartridge is loaded into a printing apparatus and printing processing is performed. In the negative film wound up in such a cartridge, the winding habit of the end portion is further strengthened. It is also considered that the negative film is accommodated in a small cartridge in accordance with the miniaturization of the camera, and even in such a small cartridge, the winding habit becomes strong similarly to the above.

For this reason, it is conceivable to correct the curl in advance by, for example, attaching the above-mentioned short leader also to the rear end of the negative film, and to carry out development processing. However, during the baking process, it must be handled with a strong curl.

At present, a mechanism (separation mechanism) for pulling out and separating a negative film from a cartridge and a mechanism (rewinding mechanism) for reengaging a negative film once pulled out with a spool in a cartridge and winding the same are known. Each is proposed as an independent device (Japanese Patent Application No. 4-212).
No. 135), by using this apparatus, the negative film can be easily separated from the cartridge, and the separated negative film can be stored again in the cartridge.

In conventional photographic film processing apparatuses such as a developing apparatus, a printing apparatus, and a splicer, a cutter is indispensable when separating a photographic film from a cartridge. Further, when cutting by the cutter, cutting waste is generated.

[0006] By integrally connecting the separating mechanism and / or the winding mechanism to such a photographic film processing apparatus, a cutter mechanism is not required, and generation of cut waste can be prevented.

[0007]

However, in the case of a negative film having a strong curl, handling of the negative film after being separated from the cartridge is troublesome, and the separating mechanism is provided upstream and downstream of a developing device, a printing device, a splicer, and the like. In addition, if the winding mechanism is provided, there is a problem in the transportability and the connection cannot be performed.

[0008] Negative films are currently used as a support for polyethylene terephthalate (PE).
T) or triacetylcellulose (TAC)
It has been proposed to apply polyethylene naphthalate (A-PEN) that has been heat treated by high temperatures. By applying this A-PEN, the coefficient of thermal expansion is small,
Since it is also made of a small amount of moisture-absorbing material, the dimensional stability is improved and the curl is hardly formed, and it is most suitable for winding and storing in a cartridge.

In view of the above facts, the present invention uses a photographic film having a support made of polyethylene naphthalate (A-PEN) heat-treated at a high temperature to reduce the curl and apply a photographic film in a state accommodated in a cartridge. It is an object of the present invention to provide a photographic film processing apparatus in which at least one of a separation mechanism and a winding mechanism can be integrally configured by improving film transportability.

4 is engaged with the locking claw 20B, and thereafter, the guide plate 172 returns to the standby position by the reverse rotation of the motor 190, whereby the engagement between the guide claw 174 and the elongated hole 90 is released. Delivered to the spool 20.
Therefore, the negative film 18 is wound up in a layer by the subsequent rotation of the spool 20 and can be stored in the cartridge 14.

As described above, by providing the locking mechanism 166 on the downstream side of the negative film transport path 116, it is not necessary to store the negative film 18 after the printing process in the cartridge 14 in a separate step, thereby reducing the number of working steps. be able to. Further, it is not necessary for the operator to touch the negative film 18 after the baking process, so that the negative film 18 can be prevented from being damaged.

Further, since the negative film 18 using A-PEN as a support has a higher tear strength than other films such as PET, TAC, etc.
The negative film 18 is unlikely to be damaged due to the engagement between the B and the circular hole 64 and the engagement between the guide claw 174 of the guide plate 172 and the elongated hole 90, and is damaged even if the negative film 18 is repeatedly detached from the spool 20. Never do. In addition, since the winding habit is small, the stopping accuracy is improved at the time of positioning during the printing process.

Further, when A-PEN is used as the support, the dimensional stability of the negative film 18 against the environment such as temperature and humidity is good, and the curl is small. Deviation (track deviation)
And the azimuth angle shift is small, the signal output is large,
Reading or writing errors can be prevented.

Further, the guide claw 174 is inserted into the elongated hole 90 while the negative film 18 is pressed by the pressing plate 196. However, in the case of the negative film 18 using A-PEN as a support, the pressing plate 196 is omitted. Is also possible.

In the second embodiment, by providing a buffer section for storing the negative film 18 in a loop shape, the transport of the negative film 18 during the printing process can be achieved.
It is possible to absorb the difference in the operation from the transportation when the negative film 18 is locked, so that the processing can be performed continuously.

The film locking mechanism 166 applied to the second embodiment is different from the film separating mechanism 62 applied to the first embodiment only in the shape of the guide plate 172. It has become. Therefore, by making this guide plate 172 detachable and replaceable with the guide plate 68 applied in the first embodiment, the guide plate 6
The cartridge 14 before printing may be accommodated in the accommodating portion 168 with the cartridge 8 attached, and the negative film 18 may be sent back to the printing position in order to reverse the negative film 18 and once separated in the fully drawn state. Thereafter, if the negative film 18 is replaced by the guide plate 172 and wound up and accommodated in the cartridge 14 again, the separation from the cartridge 14 to the winding accommodation after baking can be performed automatically.

Third Embodiment A third embodiment of the present invention will be described below.

FIG. 9 is a schematic diagram of a splicer 204 according to the third embodiment. This splicer 20
Reference numeral 4 is composed of three blocks of a sending unit 206, a joining unit 208, and a winding unit 210.

The sending section 206 is provided with a mounting table 212 on which the cartridge 14 is mounted.
The cartridge 14 placed on the cartridge 2 is held by a stopper 214. The cartridge 14 mounted on the mounting table 212 has its spool 20 engaged with the drive shaft 213, and the spool 20 is rotated by the drive shaft 213 in the pull-out direction of the negative film 18.

A film separating mechanism 62 is provided downstream of the mounting table 212. The film separating mechanism 62 has the same structure as the structure applied to the developing device 10 of the first embodiment. Therefore, the detailed structure is omitted, and the same reference numerals are given and the description of the structure is omitted. Omitted.

That is, by inserting the guide plate 68 into the cartridge 14 in a state where the negative film 18 is fully pulled out, a circular hole 64 provided at the rear end of the negative film 18 is formed.
And the locking claw 20B are separated from each other, and the negative film 18 and the cartridge 14 can be separated.

In the third embodiment, A-PEN is used as a support for the negative film 18.

The roller pair 21 is located at the most downstream side of the delivery section 206.
6 is disposed, and the negative film 18 is
, And reaches the joining portion 208.

At the joint 208, the negative film 18 is transported along a guide plate 218 provided on the front and back surfaces. A joining head 220 is provided in a middle portion of the conveyance by the guide plate 218. Joining head 2
Reference numeral 20 denotes a head main body 220A which is operated so as to approach and separate from the negative film 18, and a receiving stand 220B which holds the negative film 18 between the head main body 220A and the front end of the negative film 18. Body 2
It is configured to be temporarily stopped once it is sent between 20A and the cradle 220B. Further, the rear end of the negative film 18 separated just before is also temporarily stopped between the head main body 220A and the receiving base 220B.

A splicing tape 222 is fed between the negative film 18 and the head main body 220A, and the rear end (previous) and the front end (current) of the negative film 18 are stopped. In this state, when the head body 220A is operated, both the front and rear negative films 1
The splicing tape 222 is adhered and joined with the splicing tape 222 stretched between the eight.

A winding section 210 is provided downstream of the joining head 220 via a reservoir section 224. The winding unit 210 is provided with a shaft 226 that rotates at a constant speed, and the negative film 18 sent out from the joining unit 208 is wound around the shaft 226.

The reservoir section 224 includes two pairs of rollers 22
8, 230 are provided, and the rollers 228, 23
The negative film 18 is stored in a loop between zero. Due to the increase or decrease of the loop amount, a difference in conveyance between the joining section 208 and the winding section 210 is absorbed.

The operation of the third embodiment will be described below. When developing a plurality of photographed negative films 18 in succession, it is necessary to pull out the negative films 18 from the cartridge 14 and join them. For this reason, the cartridge 14 is mounted on the mounting table 212, and the leading end of the negative film 18 is nipped and pulled out by the roller pair 216. The tip of the drawn-out negative film 18 has a head body 220A and a receiving stand 220B.
, The transport of the negative film 08 is temporarily stopped. At this time, the rear end of the previous negative film 18 is on standby between the head main body 220A and the receiving stand 220B, and in this state, the head main body 220A operates (the negative film is held between the receiving base 220B). Thereby, the splicing tape 222 is wrapped between both the front and rear negative films 18, and the joining is completed.

[0094] In the winding section 210, the bonded negative 18 is wound around the shaft 226 while being transported at a constant speed.
A conveyance difference occurs between the intermittent conveyance at the joining section 208 and the intermittent conveyance. In the reservoir section 224, the transport difference is absorbed by the increase and decrease of the loop, so that the joining operation and the winding operation can be smoothly performed without affecting the joining operation and the winding operation.

When the negative film 18 is fully pulled out,
The motor 84 is driven to rotate the cam plate 86. As a result, the guide plate 68 moves from the standby position, is inserted from the entrance 14A of the cartridge 14, and
To the slit hole 20A. Since the guide plate 68 is inserted between the locking claw 20B and the negative film 18, the engagement of the circular hole 64 with the locking claw 20B is released in accordance with this insertion. As a result, the negative film 18 is
Separated from

As described above, by providing the separation mechanism 62 in the negative film loading section 60, the negative film 18
Can be separated from the cartridge 14 (spool 20) without cutting, and a cutting mechanism is not required. Further, it is possible to eliminate cutting waste at the time of cutting.

In addition, by applying the negative film 18 using A-PEN as a support, there is no curl at the front and rear ends of the negative film 18, the joining accuracy (alignment) is improved, and the subsequent transport reliability is improved. And meandering and jamming can be prevented.

As described above, connecting the negative film separating mechanism 62 and the negative film locking mechanism 166 to the existing negative film processing apparatus, and applying A-PEN as a support for the negative film 18 , Can eliminate the conventionally required mechanism, for example, the cutting mechanism of the negative film 18,
As a result, cutting waste can be eliminated. The negative film separating mechanism 62 and the negative film locking mechanism 1
66 is connected to an existing negative film processing apparatus without deteriorating the transportability thereof.
Can be automated, and the chance of touching the negative film 18 can be reduced, so that damage to the negative film 18 can be reduced.

[0099]

As described above, the photographic film processing apparatus according to the present invention employs a photographic film having a support made of polyethylene naphthalate (A-PEN) heat-treated at a high temperature to reduce the curl and to reduce the curl. By improving the transportability of the photographic film stored in the photographic film, there is an excellent effect that at least one of the separation mechanism and the winding mechanism can be integrally formed.
