It is configured as follows. In addition, the above-mentioned X of the photographing stand 60
A third position and a fourth position are indicated by a dashed line and a dashed double dot line, respectively, within the range of movement in the direction, but this is the range of movement of the imaging platform 60 during normal imaging. indicates that the position is between the third position 60A indicated by the one-dot chain line and the second position 60B indicated by the two-dot chain line. A first abutting part 61 of the cutter
The position 60C is a position where the photographing table 60 is positioned to receive the film sent out from the film feeding section 65 prior to the start of shooting, and the second position 60C in contact with the film taking out section 62 is a position where the shooting table 60 is positioned to receive the film sent out from the film feeding section 65 before starting shooting. This is the position to which the photographing stand 60 moves when transporting the film that has been processed to the processing section for processing.

As described above, the photographing platform 60 is made movable in the X-Y directions so that when the camera section 63 photographs images on film, it is possible to arrange and photograph a plurality of images two-dimensionally. It is. The position of the photographing table 60 is controlled by providing independent drive systems in the X direction and Y direction, using a pulse motor as a drive source, and applying a predetermined number of pulses to this in accordance with the photographing position. Although a method of moving the object a predetermined distance from the reference point is used, other methods may also be used.

The film feeding section G5 is a film feeding section G5.
4, a predetermined length of film is pulled out from the film reel 13 and sent onto the photographing stand 60. The amount of feed in this case is controlled by controlling the rotation angle of the film feed roller 14. Further, the film take-out section 62 includes a pickup roller 21 that can come into contact with and detach from the film surface on the photographing stage 60, and film transport bells 22A and 22B, and the film on the photographing stage 60 is removed by the pickup roller 221.

The processor section is roughly divided into a processor 70 and a dryer 71, and the processor 70 includes a development processor 72, a stop processor 73. It consists of a fixing processing section 74 and a washing processing section 75. Among the above-mentioned processing sections, the development processing section 72. Each of the fixing processing section 74 and the washing processing section 75 is configured to process the film while transporting it in a U-shape by disposing a large number of rollers in a processing tank. Further, the stop processing section 73 serves as a cross-over between the development processing section 72 and the fixing processing section 74.
A stop liquid reservoir consisting of two pairs of small-diameter rollers, a stop liquid supply pipe (spray nozzle), and a drip-proof plate is provided here, and while the film passes through the stop liquid reservoir, By performing stop processing, it is possible to improve the efficiency of stop processing, save space, and shorten processing time. In addition, in the figure, Fo indicates a film transport path.

The dryer 71 includes a group of transfer rollers similar to the squeeze section 76 having a large number of transfer rollers R arranged in a so-called staggered pattern, and a group of dry air blowing nozzles N arranged to face the transfer roller groups, respectively. It consists of a drying section 77. The staggered roller arrangement is effective for processing thin films, especially thin films processed using non-hardening fixers. Further, the drying air blowing nozzle N is provided with a plurality of film guide members in the width direction to prevent the film from getting caught in the drying air blowing port of the nozzle N.

The film sent out from the dryer 71 is supported by the airflow ejected from the lower surface of the dryer 71 and is accumulated in the accumulation section. The stacking section has an exhaust hole above it, through which the airflow used for the film support is exhausted. This has the effect that the film does not get stuck or folded, and the stacking process is carried out smoothly.

In the processor section, the processor 70 is structured so that it can be separated from the dryer 71 and pulled out to the back side of the camera processor main body for convenient maintenance and inspection. The driving force is transmitted to the processor 70 via a removable coupling.

(5) Processing liquid supply section A part of the processing liquid supply section is shown in FIG.
1 to 85 are a developing solution and a stop solution, respectively.

These are cartridges for fixing solution, first washing water, and second washing water. In this camera processor.

All of the processing liquid and washing water used are supplied and collected by the cartridge, completely eliminating the need for external piping connections for the processing liquid and washing water. That is, the processing liquid and washing water supplied by the cartridge are sent to each processing tank and washing tank by a pump and subjected to processing. Regarding the developer and fixer, new solutions are replenished from the cartridge according to the amount of film processed. The details will be explained below.

As shown in detail in FIG. 6, the developing processing system includes a developing processing section 72. Developer cartridge 81. Developer liquid supply pump 9
1. Developer circulation pump 91A, developer replenishment pump 91B
and a filter 91C. The circulation pump 91A is provided in the development processing tank.

A liquid inlet/outlet of the circulation system consisting of the filter 91C, a U-shaped pipe for liquid injection connected to the liquid supply pump 91 and the replenishment pump 91B, a drain port to which a drain pipe equipped with a cock is connected, an overflow pipe, etc. It is provided.

The developer cartridge 81 has a double structure in which a soft plastic bag is inserted into a hard plastic container 81A, and the developer is initially filled in the inner bag 81B. The space between the container 81A and the inner bag δlB is used for collecting developer that overflows due to replenishment that occurs during film processing. The cap 81C of the developing cartridge 81 is provided with a liquid receiving pipe connected to the liquid supply tank 91, the liquid suction pipe of the replenishment pump 91B, and the overflow nozzle of the developing processing section 720. .

The liquid suction pipe is inserted into the inner bag 81B, and the liquid receiving pipe opens into the recovery space. Further, the cap 81C is installed integrally with the liquid supply pump 91, or from the position where the cap 81C alone is fitted into the cartridge 81 as shown in FIG. 6, to the position where the liquid suction pipe is completely pulled out from the cartridge 81. It is configured so that it can be moved up to

When supplying liquid to the developing processing tank, pull up the cap 81C, set the first cartridge 81 filled with the developer, and then insert the cap δIC into the cartridge 81.
The liquid supply pump 91 may be operated by setting it to . After the above operations, preparation for processing is completed by converting the empty cartridge to a new one filled with developer.

As for the other processing systems, the fixing processing system is exactly the same as the developing processing system, and the stop and washing processing systems supply processing liquid or washing water in the cartridge between the processing tank and the cartridge only when the processor is operating. It is structured in a circular manner.

When a series of processing is completed, the developing solution and the fixing solution are stored in their respective processing tanks, and the stop solution and washing water are collected in the cartridge.

When performing the next treatment, the stop liquid and washing water collected in the cartridge are reused.

When the amount of film processed by the processing liquid and washing water supplied with the cartridge reaches a specified amount, or when a specified period of time (for example, one week) has elapsed since the start of use of the cartridge, the alarm device described below will be activated. At this point, replace all of the processing liquid and wash water according to the instructions. When replacing the cartridge, the processing liquid in the developing and fixing processing tank must be collected separately using the drain pipe, but other processing liquids and washing water are collected in the cartridge, so you can simply replace it. Good. At this time, the cap of the cartridge is pulled up as described above, which has the advantage that the operation is extremely simple and the operator does not get his hands dirty.

Note that the processing tank is equipped with an electrode switch (see Fig. 6, 72A) to monitor the level position of the processing liquid.
It is configured to issue an alarm if the liquid level drops.

IO is an image section. Note that the photographing in this embodiment apparatus is performed from the back side of the screen shown in FIG.
After the IO is photographed in this order, the title section and the data section are photographed. During this time, the film F is held on the photographing platform 60 shown in FIG.
In the process of being transported step by step to the position B, the image sections 11 to I
, is also moved by one image pitch in the Y direction (towards the back of the figure) and returned to the position 60A in the X direction, and then is moved stepwise again from the position 60A to the position 60B. In the process of being transferred, the image sections 16 to IIO are photographed. Furthermore, at the image capturing position of the image section 1100, the title section T and the data section are captured. In addition,
If the number of documents to be photographed is less than 10, after the document has been photographed, the photographing table 60 is moved to the photographing position of the title section T and data section, and the photographing of the title section T and data section is started. Needless to say, it will move.

All operations of the device of this embodiment are controlled by a microcomputer. The processing flowchart is shown in FIG. 8 and subsequent figures, and the operation will be explained based on this. The details of the subroutine in FIG. 8 are shown in FIGS. 9 to 22.

An outline of the operation of the apparatus of this embodiment will be explained based on FIGS. 8(5) and 8(B) as follows.

(1) Initial operation Steps 101 to 109 in FIG. 8 (5) are so-called mechanical and drowsy initial setting steps, in which the processing liquid in the processing section is replenished (step 105, r-liquid level control (29) See figure) J).

The remaining film in the camera section is also ejected (step 109 "Film ejecting operation (see Figure 1)"). This operation is performed only once when the power is turned on.

(2) Heat-up operation Steps 110 to 114 correspond to the five steps, and the next operation does not proceed until step 114, when an increase in the developing temperature is detected.

(3) Actual work operation (I) Actual work becomes possible by detecting the development temperature rise in step 114. The following operations are automatically repeated as long as the power of the device is not turned off.

If instructions for actual work are given, step 116 ``Liquid Supply Control'' (see Figure 12) checks whether or not the liquid supply switch is suppressed, step 117 ``Alarm Check'' checks whether there is an alarm, and step 122 ``Temperature Adjustment'' is performed. ” while monitoring the developing temperature respectively, the shutter button depression is monitored in step 124. As long as the shutter button is not pressed, "READY" is displayed and waits.

(4-I Actual work operation (6) When the shutter button is pressed, the display shows “WAIT”
Then, the film is set (feeding, cutting, holding by suction). When the film setting is completed, the process moves to step 131 "Frame Routine". The details of the "frame routine" are shown in FIG. First, the display is REA

(See Figure 13), set the mask (see Figure 13).
It is possible to set the double magnification (see the "Mask Manual" step in Figure 20), set the lamp (see the "Rung" step in Figure 21), set the exposure, etc.

The "frame routine" further includes "film discharge control (see Figure 13)" for discharging the previously shot film, and "replenishment control (see Figure 14)" for controlling the replenishment of the film. etc., and monitor the alarm and shutter button suppression. If the shutter button is not pressed, line feed (skip from column A to column B), assuming that the shooting is not in the normal order.
Wait while checking the belly button skip (skip to title shooting position), etc.

When the shutter button is pressed, it controls the lamp, shutter (takes pictures, moves the film position, etc.)
The next shooting position (title position if 10 images have been shot) is displayed on the film indicator. Title photography is performed by a "title routine (see FIG. 17)."

“Frame routine” is also used in “Title routine”
Similarly, until the shutter button is pressed, input is accepted in the "key manual input acceptance" step. Also,
Other checks are performed similarly. When the shutter button is pressed, title lamp control, shutter control (shooting), and film ejection control (first
(See Figure 8).

``The film ejection control J step feeds the film that has been photographed at high speed halfway through the processing section, and finally sends it through the processing section at the same speed as the processing section, and at the same time checks the number of films for replenishment.

(5) Processing in case of abnormality FIG. 15 is a diagram showing details of alarm processing.

The "1 week alarm" issues an instruction to replace the processing solution when one week has passed or when 800 sheets have been processed, whichever arrives first, and its details are shown in FIG. If the alarm is issued when one month or more has elapsed since the last time the processing section was cleaned, an instruction is given to clean the processing section as well. A "misfeed alarm" is an alarm that occurs when there is a problem loading film into the camera section.

It goes without saying that various other types of alarms can be provided as well.
