Description

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 in which a cartridge for storing a photographic film having polyethylene naphthalate (A-PEN) heat-treated at a high temperature as a support on a spool can be loaded.

[0002]

2. Description of the Related Art In recent years, it has been proposed to rewind a negative film that has been subjected to development processing to a cartridge and return it to a customer. In this case, by rotating the spool shaft for accommodating the negative film, so-called bellows can be easily carried out, and in the case of requesting additional printing, this cartridge is loaded into the printing apparatus and the printing process is carried out. The negative film wound up in such a cartridge has a stronger winding tendency at the end portion. 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 curling tendency becomes strong similarly to the above.

For this reason, it is conceivable that the curl habit, such as attaching the short leader to the rear end of the negative film, is corrected in advance and the development process is performed. However, it must be handled in a state with a strong curl during the baking process.

At present, a mechanism (separation mechanism) for pulling out and separating the negative film from the cartridge (separation mechanism) and a mechanism for re-engaging the negative film once pulled out by re-engaging with the spool in the cartridge (winding mechanism), They have been proposed as independent devices (Japanese Patent Application No. 4-212).
No. 135), by using this device, the negative film can be easily separated from the cartridge, and the separated negative film can be stored in the cartridge again.

By the way, in a conventional developing device, printing device, photographic film processing device such as a splicer, a cutter is indispensable for separating the photographic film from the cartridge. In addition, cutting scraps are generated when cutting with this cutter.

By integrally connecting the separating mechanism and / or the winding mechanism to such a photographic film processing apparatus, a cutter mechanism becomes unnecessary and it is possible to prevent the generation of cutting scraps.

[0007]

However, with a negative film having a strong curl, it is troublesome to handle the negative film after it has been separated from the cartridge, and the separating mechanism is provided upstream and downstream of a developing device, a printing device, a splicer and the like. Also, if a winding mechanism is provided, there is a problem in transportability, and they cannot be connected.

The negative film is currently used as a support for polyethylene terephthalate (PE).
Instead of T) or triacetyl cellulose (TAC),
It has been proposed to apply polyethylene naphthalate (A-PEN) which has been heat treated by high temperature. By applying this A-PEN, the coefficient of thermal expansion is small,
Since it is small in moisture absorption, it has good dimensional stability and is less prone to curling, which makes it ideal for winding and storing in cartridges.

In consideration of the above facts, the present invention applies a photographic film having polyethylene naphthalate (A-PEN) heat-treated at a high temperature as a support to reduce the curling habit, and a photograph in a state of being housed in a cartridge. An object of the present invention is to obtain a photographic film processing apparatus capable of integrally forming at least one of a separating mechanism and a winding mechanism by improving the transportability of the film.

And a driving means for reciprocating the separating member from the retracted position to the insertion position when the photographic film is fully drawn out.

According to a third aspect of the present invention, the winding mechanism holds the cartridge at a predetermined position, a retracted position separated from the cartridge held by the holding means, and a photograph of the cartridge. A holding portion is formed which is inserted from a film drawing port and is movable to an insertion position corresponding to the engaging portion of the spool and the photographic film, and which holds a rear end of the photographic film on a movement locus to the insertion position and the insertion. A delivery member that delivers the rear end of the photographic film to the spool at the position, and a drive unit that reciprocates the delivery member from the retracted position to the insertion position in a state where the rear end of the photographic film reaches the movement path. It is characterized by being.

[0013]

According to the first aspect of the invention, polyethylene naphthalate (A-PE) is used as a support for photographic film.
N) applies. A-PEN has mechanical strength, particularly high elastic modulus, and has a glass transition temperature (Tg) of 119 ° C.
And high enough. The compounds of PEN are as follows. PEN: [2,6-naphthalenedicarboxylic acid (NDCA) / ethylene glycol (EG) (100/100)] Tg = 119 ° C. By heat treating (annealing) the above PEN at a high temperature not exceeding the glass transition temperature (Tg). Properties such as (A-PEN), strength, dimensional stability, and thinning are improved, and the winding habit due to being wound on a spool can be reduced.

In a photographic processing apparatus having a separating mechanism, since the photographic film drawn out from the cartridge has a small curl, even if the photographic film is continuously conveyed to the next step without correcting the curl after the drawing, it is a so-called. It can be stably transported without causing jamming. Further, even when the photographic film is stored in the cartridge again by the winding mechanism after the predetermined processing, since the winding tendency is small, the photographic film can be reliably engaged with the spool and wound around the spool.

Further, it is not necessary for the operator to touch the negative film 18 after the baking process, and the negative film 18 can be prevented from being damaged.

Since the negative film 18 using A-PEN as a support has a higher tear strength than other films such as PET and TAC, the locking claw 20 of the spool 20 is used.
The negative film 18 is less likely to be damaged by 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 the negative film 18 is repeatedly detached from the spool 20 and damaged. There is nothing to do. Further, since the winding tendency is small, the stopping accuracy is improved at the time of positioning during the baking process.

Further, when A-PEN is applied as a support, the negative film 18 has good dimensional stability with respect to the environment such as temperature and humidity, and has less winding tendency, so that the magnetic recording layer 18B for the magnetic head is formed. Deviation (track deviation)

The delivery section 206 is provided with a mounting table 212 on which the cartridge 14 is mounted.
Cartridge 14 placed on No. 2 is held by stopper 214. The spool 20 of the cartridge 14 mounted on the mounting table 212 meshes with the drive shaft 213, and the drive shaft 213 rotates the spool 20 in the drawing direction of the negative film 18.

A film separating mechanism portion 62 is arranged on the downstream side of the mounting table 212. The film separating mechanism portion 62 has the same structure as that applied to the developing device 10 of the first embodiment, and therefore the detailed structure will be omitted and the same reference numerals will be given to describe the structure. Omit it.

That is, by inserting the guide plate 68 into the cartridge 14 with the negative film 18 fully drawn out, the circular hole 64 provided at the rear end of the negative film 18 is inserted.
The locking claw 20B is separated from each other, and the negative film 18 and the cartridge 14 can be separated.

Also in this third embodiment, A-PEN is used as the support for the negative film 18.

A roller pair 21 is provided on the most downstream side of the sending section 206.
6 is provided, and the negative film 18 is provided with this roller pair 216.
It is nipped and conveyed to reach the joint portion 208.

At the joint portion 208, the negative film 18 is conveyed along the guide plates 218 provided on the front and back surfaces thereof. A splicing head 220 is arranged in the middle of the conveyance by the guide plate 218. Splicing head 2
Reference numeral 20 is composed of a head main body 220A that is operated so as to move toward and away from the negative film 18, and a cradle 220B that holds the negative film 18 between the head main body 220A, and the tip of the negative film 18 is the head. Body 2
It is configured to be temporarily stopped when it is fed between 20A and the cradle 220B. Further, the rear end of the negative film 18 separated one time before is also temporarily stopped between the head 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 portion (previous time) and the front end portion (current time) of the negative film 18 are stopped. In this state, when the head main body 220A is activated, both the front and rear negative films 1
The splicing tape 222 is attached and bonded in a state of being hung between the eight.

On the downstream side of the joining head 220, a winding section 210 is arranged 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 and 230 are provided, and these rollers 228 and 23 are provided.
The negative film 18 is stocked in a loop shape during the zero period. By increasing / decreasing the loop amount, the conveyance difference between the joining portion 208 and the winding portion 210 is absorbed.

The operation of the third embodiment will be described below. When a plurality of the negative films 18 that have been photographed are continuously developed, it is necessary to pull out the negative films 18 from the cartridge 14 and join them. Therefore, the cartridge 14 is mounted on the mounting table 212, and the leading end portion of the negative film 18 is held by the roller pair 216 and pulled out. The leading end of the drawn negative film 18 has a head body 220A and a cradle 220B.
When it reaches the interval between and, the conveyance of the negative film 08 is once stopped. At this time, the trailing edge of the previous negative film 18 is on standby between the head main body 220A and the receiving base 220B, and the head main body 220A operates in this state (the negative film is sandwiched by the receiving base 220B). As a result, the splicing tape 222 is stretched between the front and rear negative films 18, and the joining is completed.

In the winding section 210, the joined negative piece 18 is wound around the shaft 226 while being conveyed at a constant speed.
A conveyance difference occurs between the joint portion 208 and the intermittent conveyance. The reservoir section 224 absorbs this conveyance difference by increasing and decreasing the loop, so that the joining and winding processes can be performed smoothly without affecting the mutual joining and winding operations.

When the negative film 18 is fully drawn out,
The motor 84 drives and the cam plate 86 rotates. As a result, the guide plate 68 moves from the standby position, is inserted from the inlet / outlet port 14A of the cartridge 14, and the spool 20
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 according to this insertion. As a result, the negative film 18 becomes the spool 20.
Separated from.

As described above, by providing the separation mechanism 62 in the negative film loading portion 60, the negative film 18
Can be separated from the cartridge 14 (spool 20) without cutting, and a cutting mechanism is unnecessary. In addition, it is possible to eliminate cutting waste when cutting.

Further, by applying the negative film 18 having A-PEN as a support, there is no curl habit at the front and rear ends of the negative film 18, the bonding accuracy (alignment) is improved, and the transportation reliability after that is improved. However, meandering and jamming can be prevented.

As described above, connecting the negative film separating mechanism portion 62 and the negative film locking mechanism portion 166 to the existing negative film processing apparatus, and applying A-PEN as a support for the negative film 18. By combining the ,, it is possible to eliminate the mechanism that was conventionally essential, for example, the cutting mechanism of the negative film 18,
As a result, cutting waste can be eliminated. Further, the negative film separation mechanism portion 62 and the negative film locking mechanism portion 1
66 is connected to an existing negative film processing apparatus without deteriorating the transportability, and the work that has been performed manually until now, for example, the negative film 18 after the baking process has been completed.
Since the work of accommodating the negative film 18 in the cartridge 14 can be automated and the chance of touching the negative film 18 can be reduced, damage to the negative film 18 can be reduced.
