Description

[Detailed Description of the Invention] This invention provides exposure (photography), development, fixing, washing,
The present invention relates to a method for controlling the length of a film leader/trailer section in a camera processor that allows each drying process to be performed consistently.

As shown in Figure 1, the camera processor performs an exposure process 1 in which an original is exposed (photographed) onto a photographic film using a lens system and a light source, and the film exposed in process 1 is once stored and then cut and stored. A storage process 2, a development process 3 in which the film cut and sent out after storage is developed with a developer, a fixing process 4 in which the film developed in process 3 is immersed in a fixer and fixed; The process includes a washing process 5 in which the fixed film is washed with water, and a drying process 6 in which the film washed in process 5 is dried by heating with a heater or the like.

FIG. 2 shows a schematic configuration of the camera processor according to the transport path of the film 10. The film (unphotographed film) 10 wound around the supply reel 11 is conveyed by rollers 12A, 12B, 12C,
12D, the film 10 is wound around an autoreel 22 in a storage chamber 20, and the film 10 is slit by the light reflected from the original 14 from a light source 13 through a lens system 16 on a roller 12C. It is becoming exposed. And manuscript 1
4 is provided with a shutter 15 that opens only during exposure to form an optical path, and in front of the storage chamber 20 is provided a cutter 17 for cutting the exposed film 10 to an appropriate length. has been done. At the entrance of the storage chamber 20, the transported film 1 is stored.
Rollers 21A and 21B for taking in zero are provided in a pressed state, and rollers 21A and 21B
The film 10 that has been picked up by the rollers 21B is automatically mounted on the core 23 of the auto reel 22 and wound through a rotatable mounting roller 26 attached to the roller 21B by a guide arm 25. A rotating plate 27 is provided coaxially with the auto-reel 22 in the vicinity of the auto-reel 22, and a reel drive for winding the film 10 by a belt that comes into contact with the surface of the rotating plate 27. Means 2
4 are arranged. Also, the exposed film 10A wound on the autoreel 22 in the storage chamber 20
is transported to a subsequent processing system 30 by a separate drive mechanism, and this processing system 30 performs a developing process 3, a fixing process 4, and a water washing process 5.
After the drying process 6 is carried out, it is further conveyed by rollers or the like and wound around a take-up reel 40. Furthermore, the original 14 is supplied to the exposure section by an auto feeder.

Such a camera processor may perform long processing or strip processing depending on the length of the film 10 or the length of the film to be imaged. Since the processing methods are different for long film processing and strip processing, the length from the leading edge of the film to the beginning of the photographed frame, in other words the length of the leader section, and the length from the end of the photographed frame to the rear end of the film, i.e. Preferably, the lengths of the trailer sections are different. Figures 3A and 3B show this situation. In the case of strip processing, the length of the leader part A1 and the length of the trailing part B1 are set to about 10 to 20 cm, respectively, as shown in Figure A. In this case, the length of the leader part A2 and the length of the trailer part B2 are each about 1 to 2 m, as shown in FIG. The reason why the lengths of the leader part A1 and the trailer part B1 are shortened in the case of strip processing is to adjust the amount of film used without winding it around a reel in the case of strip processing. The reason why the leader section A2 and trailer section B2 are made longer in the case of long film processing is to secure the necessary space because in the case of long film, the film is often wound around the reel of a leader or reader printer, etc. This is because it is necessary.

The present invention has been made in view of the above circumstances, and the length of the leader/trailer part can be selectively varied depending on whether the film is a strip film or a long film.

This invention will be explained below.

This invention consistently performs the processes of exposing, developing, fixing, rinsing, and drying the film, and also cuts the film sent from the exposure section with a cutter and stores it in a storage chamber, and then develops, fixes, and dries the film.
This relates to a method for controlling the length of the leader/trailer section of a camera processor that is wound onto a reel as needed after a process of washing and drying. Therefore, while selectively varying the length of the leader section from the leading edge of the film to the start of exposure,
The length of the trailer section from the end of exposure can be selectively varied by operating the cutter.

That is, in this invention, as shown in FIG.
Detection switch S for detecting attachment of the take-up reel 40
1 and the film 1 on the supply reel 11.
A remaining amount detection switch S2 for detecting the remaining amount of 0 is provided, and a film detection sensor for detecting the film 10A sent from the storage chamber 20 to the processing system 30.
We have a FS. The leader portion of the film 10 is formed according to the flowchart shown in FIG. 4, and the trailer portion is formed according to the flowchart shown in FIG.

To form the leader section, as shown in FIG.
1 and determines whether a new film has been loaded. If a new film has not been loaded, normal processing is performed (step 1).
S20). When the remaining amount detection switch S2 is turned from on to off and it is determined that a new film 10 has been loaded, a separate developing button (not shown) is turned on to start the developing process (step S2). Thereafter, it is determined by the detection switch S1 whether or not the take-up reel 40 is loaded (step S3), and if the take-up reel 40 is loaded, it is determined that a long film is being processed. In order to form a long leader section necessary for the long film, empty feeding (for example, 1 to 2 m) is performed (step
S4) After the film 10 is loaded on the autoreel 22 in the storage chamber 20, the auto feeder is turned on to start photographing (step S5), and then exposure is performed (step S6). By the way, if it is determined in step S3 that the take-up reel 40 is not loaded, a new film 10 is fed blankly (for example, 1 to 2 meters) to remove the fogged part (step S7), and then cut with the cutter 17. The fogged portion is cut off and sent to the developing process (step S8). This makes it possible to form a film leader (for example, 10 to 20 cm) necessary for stripping. Thereafter, it is determined whether the film wound on the auto-reel 22 in the storage chamber 20 is sent out to the developing process or below and detected by the film detection sensor FS (step S9), and after being detected, the film is photographed. To start, turn on the auto feeder and perform exposure (steps S10 and S6).

On the other hand, when the above-described exposure process progresses and a trailer portion is to be formed on the exposed film, it is determined whether the remaining amount detection switch S2 is on or not (step S31), as shown in FIG. ),
If the remaining amount detection switch S2 is off, it means that there is still some film left, so normal processing is performed (step S20). When the remaining amount detection switch S2 is turned on and the remaining amount of the film 10 wound around the supply reel 11 becomes low, it is determined whether the detection switch S1 is turned on or not, that is, whether the take-up reel 40 is loaded or not. It is determined whether or not a long film has been processed (step S32), the auto feeder is turned off to prohibit shooting (step S33), the developing button is turned on (step S34), and the long film is processed. A blank feed (for example, 1 to 2 m) is performed to form a long trailer portion necessary for the length of the film, and the process moves on to post-cutting processing (steps S35 and S36). In addition, if the detection switch S1 is off, it is determined whether the additional shooting amount has exceeded (step S37), and if the additional shooting amount has been exceeded, the auto feeder is turned off (step S37). Step S38), then turn on the development button and feed as necessary for stripping (e.g. 10-20cm)
and move on to post-cut processing (step
S39, S40, S36).

As described above, according to the present invention, the take-up reel 4
0 is installed, the detection switch S1 detects that long film processing is being performed, and the first operation of the developing button after loading the film performs a blank feed of approximately 1 to 2 m, and then the auto feeder is activated. and start shooting. When a specified amount of long film has been taken, the remaining amount switch S2 is activated, the auto feeder is turned off, and the operator is notified that the developing button is to be pressed. When the developing button is pressed, the film is moved approximately 1 to 2 meters, and then the cutter 17 is operated and the film in the storage chamber 20 is sent to the processing system 30 at the subsequent stage. on the other hand,
In the case of strip processing, the first operation of the developing button after loading the film performs a blank feed of about 1 to 2 meters, and then the cutter 17 is operated to send the blank feed film (fogging film) to the processing system 30. After that, operate the auto feeder to make it ready for photographing. After the photographing is completed and the developing button is turned on, the film is fed approximately 10 to 20 cm, and then the cutter 17 cuts the film. An alarm is output even after the remaining amount detection switch S2 is turned on, but the auto feeder is not turned off and a certain amount of additional photography is possible. When the predetermined amount of additional photography is taken, the auto feeder is turned off and the developing button is turned off. When is pressed, the film is moved approximately 10 to 20 cm, and then the cutter 17 is operated and the film is sent to the processing system 30.

In the above-described embodiment, the selection between elongate processing and strip processing is performed by the detection switch S1 that detects the attachment of the take-up reel 40, but it may also be performed by a manual switch or button. Furthermore, the amount of film to be photographed may be measured by measuring the amount of film wound around the autoreel 22 in the storage chamber 20 instead of using the remaining amount detection switch S2. The reference length may be selectable.

As described above, according to the length control method of the present invention, in a camera processor capable of photographing and developing a roll film of any length, the length of the film in the leader/trailer part can be shortened during strip processing and long. When processing the film, it can be made longer, reducing running costs, and in the case of longer films, it is possible to secure a leader/trailer part necessary for hanging the film on a leader, reader printer, etc.
