Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photographic processing machine that performs a series of processing operations from photographic printing to development while intermittently drying a long photographic paper wound into a roll in predetermined lengths. This invention relates to an improvement in a stocker section for long photographic paper that is interposed between a printer and an automatic developing device.

I believe that one of these types of photo processing machines is a printer that prints photos by intermittently drying a long photographic paper wound into a roll in predetermined lengths. The printed long photographic paper is guided by a guide roller group consisting of an upper roller that cannot move up and down and a lower roller that can move up and down, which are arranged alternately up and down, and then it is guided by a cutter. Each frame is cut, and each cut sheet of photographic paper is sent to a developing device equipped with a sheet-like photographic paper conveying member that can be individually conveyed using a conveyance device that can convey each frame individually. Automatic photo processing machines were introduced, but in a photo processing machine that automatically performs a series of processing operations from photo printing to development, first, a long piece of photographic paper is passed through a group of guide rollers arranged alternately above and below. Distortion occurs due to forced bending in the longitudinal direction while being guided and guided, and when it is cut frame by frame, it is unavoidable that it appears as curls that significantly impede subsequent development processing, etc. Not to mention its shortcomings, there are undeniable drawbacks such as the cumbersome operation of having to wrap a long photographic paper over a group of guide rollers when it is first used. It increased with the spread of cameras.

Therefore, the present applicant set out to improve this, which is the biggest drawback or difficulty, and developed a practical application in 1973 to replace the conventional guidance roller group of this kind.
We have developed a printer equipped with a stocker that stores long photographic paper in a loop, as described in the specification attached to the application No. 175300 [Utility Model Application No. 53-93225], and we have developed a printer equipped with a stocker that stores long photographic paper in a loop. Although it has been possible to provide a printer that eliminates the above-mentioned drawbacks and difficulties in processing machines, recently it has been possible to eliminate the automatic sorting device and connect this printer and an automatic developing device in a series. There was a need for an automatic photo processing machine that could process printed long photographic paper as a long sheet of photographic paper instead of cutting it into sheets of photographic paper one frame at a time.

Therefore, the present applicant has added innovations to the stocker that the present applicant has developed and for which he has previously filed an application for utility model registration, and has further improved the stocker to create a connection between the conventional printer and automatic developing device. Easy to install,
Furthermore, we have been able to develop a stockcar that can fully meet current demands and demands.

Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

In the figure, A has a mounting section for long photographic paper P that is wound into a roll and has cut marks etc. applied thereto, from which the long photographic paper P is intermittently dried in predetermined lengths. The drying roller, the photo printing section, the punch section that moves during the photo printing operation in the photo printing section, the tension roller, etc. are installed in the machine frame on the machine stand in this order, making it much easier than conventional printers. With any printer you can imagine,
B is a development process that includes a water washing process on a long photographic paper P that has been photoprinted in printer A;
This is also a conventional automatic developing device in which a large number of processing tanks are arranged in a series for carrying out so-called developing processes such as bleaching, fixing, stabilization, and hardening processes. This is a stocker for long photographic paper P that we were able to develop.

Therefore, the explanation of the printer A and the automatic developing device B will be omitted, and the stocker C of the long photographic paper P according to the present invention will be explained below.

Now, in the stocker C of the long photographic paper P according to the present invention, 1 is a light-shielding casing, and 2 is a guide track base plate T ₁ in the printer A.
A feeding roller is used to introduce the exposed length of photographic paper P that is fed along the casing 1 into the casing 1 in a loop shape, and this roller is connected to a torque motor _M1 . It consists of a driving roller 3 whose rotation may be stopped due to friction with the printer A, and an elastic roller 4 which is brought into elastic contact with the driving roller 3. It is also possible to eliminate the roller and use this feeding roller 2 as a substitute for the tension roller.
is a feed roller that feeds out a long photographic paper P from inside the casing 1, and this is a stepping motor.
The long photographic paper P consists of a drive roller 6 rotated by _M2 in synchronization with the operation of feeding out the long photographic paper of the feed roller in the printer 1, and an elastic contact roller 7 brought into elastic contact with the driving roller 6.
It is provided along the guideway platform _T2 . Y is a cut mark detector, 8 and 9 are cutter blades operated by cutter operating motor CM,
Reference numeral 10 denotes a roller for feeding the long photographic paper P to the automatic developing device B. This roller 5 can also be used for this purpose, so although it is not necessary, a driving roller 11 connected to a motor _M3 is provided. and an elastic roller 12.

Furthermore, inside the casing 1, the casing 1
Detectors R ₁ , R 2 and _{R 3 detect} the amount of long photographic paper P stored in the casing 1 from the state of the loop formed by the long photographic paper P within the casing 1;
etc. are provided. By the way, the detector _R1 detects that the loop formed by the long photographic paper P is at the lower limit state.
The cut mark detector Y that detects the cut mark attached to the _long photographic paper P is activated, and when the cut mark detector Y detects the cut mark, switches y ₁ and y ₂ are activated.
, close self- _holding switches x ₄ and _cm to operate relays is cut at a predetermined position, the cutter blades 8 and 9 return to their original states, the switch cm is released, and the cutter operating motor is activated.
While stopping the CM instantly, the switch _y3 is opened, and the relay _X1 opens the switch _x1 to stop the rotation of the stepping motor _M2 and interrupt the operation of the feed roller 5.

In addition, the installation position of the detector R ₂ in the casing 1 can be adjusted up and down, and this detector
R ₂ indicates that the length of the loop formed in the casing 1 is such that the length of the forward part of the long photographic paper P cut by the cutter blades 8 and 9 is such that it can be continuously processed by the automatic developing device B. This is to detect whether the length of the loop _p2 has become
It can be of various configurations, such as having a length starting from 0. ), when this is detected, the self-holding switch x ₃ is closed, the switch x ₁ is closed by the relay X ₁ , and the motor M ₂ for operating the feed roller 5 is operated. At the time of interruption, this is reactivated, and at the beginning of use of printer A, the feed roller 5 is kept on standby until loop _p2 is reached.

Furthermore, the detector _R3 detects whether the loop has reached the upper limit state of the loop _p3 , and lights up the lamp L etc. in the printer A to notify the stock amount in the stocker C, or as the case may be. It is also possible to temporarily interrupt the operation of the photo printing section, but this should be constructed with a bottom part and an upper limit switch as in Utility Model Application No. 175300/1989 [Utility Model Application No. 93225/1983]. However, it is not necessary to install a detector.

In the figure, numeral 15 is a conveyor roller for the long photographic paper P attached to the automatic developing device B, and S is a switch.

Stocker C according to the present invention has the above-mentioned configuration, and as shown in the figure, it is interposed between printer A and automatic developing device B, and these are connected in series and electrically connected. , a long photographic paper P is mounted on the mounting section of the printer A, the leading end of which is led out along a guideway base plate _T1 via a feed roller, and fed into a casing 1 by a feed roller 2.
If the long photographic paper P is stretched in a straight line between the paper and the feed roller 5 and each part is operated, the long photographic paper P is fed out intermittently by a predetermined length, and when it stops, the photo printing is performed in the photo printing section. The loop formed by the long photographic paper P inside the casing 1 is
The feed roller 5 does not operate until the state of loop p ₂ is reached, and waits, and is activated by the detection operation of the detector R ₂ that detects that the state of loop p ₂ has been reached.
The long photographic paper P is continuously sent to the automatic developing device B without being cut, and the automatic developing device B develops the series of photographic papers as they are.

By the way, due to the replacement of negatives in the photo printing section of printer A, the loop of the long photographic paper P formed in the stocker C becomes smaller than the loop _p2 (at this time, the feed roller 5 is self-retaining). When the detector R ₁ detects that the feeding operation of the long photographic paper P is not interrupted by the switch x _{3 )} , the cut mark detector Y is activated by this detection operation. ,
When this is detected, on the one hand, the cutter blades 8 and 9 are operated by the cutter operating motor CM to cut the long photographic paper P, and on the other hand, the rotation of the stepping motor M ₂ for operating the feed roller 5 is looped. Let it stop until it becomes loop p ₂ . The front part of the long photographic paper P cut by the cutter blades 8 and 9 is transported and processed by the conveying member on the automatic developing device B side, but the tip of the rear part is not at the position of the cutter blades 8 and 9. It will be placed. This also makes it possible to minimize the length of photographic paper remaining between the photo printing section and the cutter blades 8 and 9 when the operation of each section of the printer A is stopped.

This detector R ₂ determines whether the length of the loop formed in the casing 1 is the same as the length of the forward part of the photographic paper P cut by the cutter blades 8 and 9 and processed by the automatic developing device B. Since it is installed at a position where it can be detected whether the loop _p2 has a possible length, the length of the portion of the photographic paper cut by the cutters 8 and 9 from the long photographic paper P is the minimum length. The developing process will still be carried out even if the paper is in the same position, and since the installation position of this detector R ₂ can be adjusted up and down, it can also be used as an automatic developing device equipped with a conveying member for conveying photographic paper of different lengths. It can also be made into a series of processors.

In addition, the above-mentioned stocker C of the present invention includes:
Interposed between printer A and automatic developing device B,
In addition to constructing a series of photographic processing machines together with these two, the present applicant has previously applied for utility model registration for this Stotzker C.
As in No. 175300 [Utility Model Publication No. 53-93225], it is incorporated as a component of printer A, and this printer A is mounted on a long photographic paper P that is wound into a roll and has cut marks etc. Next to the feeding roller which feeds out the long photographic paper P intermittently by a predetermined length from the feeding section, there is a punch which is connected to the photo printing section and, if necessary, to the photo printing operation of the photo printing section. The cut mark in the description of the above embodiment can be constructed by placing a stocker C such as the one described above in the present invention. A punch hole drilled in P can also be used.

As is clear from the above description, the long photographic paper stocker for the photographic processing machine according to the present invention has the above-described configuration, and (a) can store a large amount of photographic paper after photographic printing; Even if there are some differences in processing capacity or processing operations between the automatic developing device and the automatic developing device, there is no longer a need for troublesome adjustments to be made one by one.

(b) In addition, the photographic paper after printing is stored in a free-form loop in the stocker, which causes curling, which is the biggest obstacle in the development process using an automatic developing device. No distortion is induced.

(c) Since there are no rollers for guidance or guidance in this stocker, it is easy to carry out long photographic paper.

(d) Furthermore, at the end of the photo printing operation by the printer, the amount of remaining photographic paper from the photo printing section of the printer can be minimized.

(e) In particular, in the casing of the stocker of the photoprocessing machine according to the invention, the length of the loop formed in the casing outside the detector _R1 is
A detector R2 is installed to detect whether the length of the first part of the photographic paper cut by the cutter has reached a length that can be conveyed and developed by the photographic paper conveying member in the _automatic developing device. Therefore, an automatic developing device that processes photographic paper after photo printing is connected in series with a printer, instead of cutting it into sheets of photographic paper one frame at a time, to create a highly efficient photographic processing machine. Now I can do it.

(f) Furthermore, the installation position of the detector R ₂ has a vertically adjustable barrel, which allows connection between an automatic developing device equipped with a conveying member for conveying photographic paper of different lengths and a printer. I got used to it.

Therefore, the present invention connects a printer and an automatic developing device that develops a long photographic paper without cutting it into sheets of photographic paper one frame at a time. However, it can be said that it has made it possible to provide a highly efficient photographic processing machine.
