Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement for expanding the use of a color copying device using a silver halide photosensitive material so that it can also be used as a developing device.

[Prior art] ``Imagewise exposure and development and finishing processing on silver halide photosensitive materials involves work in a darkroom, and in the case of color photosensitive materials in particular, imagewise exposure and development finishing processing must be carried out in the dark. There wasn't. Therefore, even though some mechanization has progressed in Step 1 of this process, the process still had to be handled carefully by skilled personnel in a dark room.

As a special case, automatic processing systems such as the Sakura Print System were developed for the popular size of color photographs, and the 9th
As shown in the figure, a roll-shaped silver halide photosensitive material 12a placed in a light-tight magazine 12' that is shielded from light is loaded into a light-tight printer 1a, which is exposed to image exposure in a bright room automatically by the exposure device 3. The photosensitive material 12b that has been image-exposed
The magazine is wound up into a light-tight magazine 12° which is separately prepared and is loaded into a light-tight developing device 1b which is light-tight as shown in FIG. Bleach-fix tank 30 stabilization tank 31, 32. An automated system is put into practical use in which the processed photosensitive material 12c is processed through a series of processes in the drying section 35, and is finally cut into sheet-like photographs by a cutter device 1c, screen by screen, as shown in FIG. has been made into

As another example, as shown in FIG. 12, when a roll-shaped silver halide photosensitive material 12a placed in a light-shielding, light-tight magazine I2° is loaded, a sheet-shaped sheet cut to a length by a cutting device 22 is cut. Silver halide photosensitive material or transport device 1
3, the document on the W and stacking table 2 is exposed imagewise at a position 40 where it is imaged by the scanning exposure section 3 constituted by an exposure lamp 4 mirror 5.6.7.9.10 and a lens 8, and then developed. Tank 25. Bleach-fix tank 30. Stabilization tank 31.3
A fully automatic copying apparatus 1 has also appeared in which a series of processes are performed in a developing processing section 24 including a color copy sheet 12f and a drying section 35, and a color copy sheet 12f is finished and collected.

However, although it can be said that these devices have achieved their purpose in terms of freedom from darkroom work, they have
From an efficiency standpoint, the situation is not necessarily satisfactory.

[Problem that the invention sought to solve]

In other words, the former type of equipment is very efficient and has excellent operability for popular, regular-sized products, but for small-lot products of other sizes, there are few opportunities to use it, and it is difficult to produce finished products. Since there is a lot of waiting time and therefore a very long stagnation time until completion, application of this method to such small quantities is inefficient and completely impractical.

The latter is a fully automatic device that connects and integrates each process and is light-tight, so it is free from darkroom work and has good operability. In order to accommodate various sizes, the magazine 12 has to be replaced, and the range of application has been considerably expanded. However, if the silver halide photosensitive material or test piece that has already been exposed by another exposure device can be used as the sole function of the developing device, which processes it by introducing it into the process after this reference development, the uses of this device will be further expanded. I think that the.

In Utility Model Application No. 61-86922, the present applicant adopted a system in which a part of the conveyance path of the photosensitive material supply and conveyance unit was branched and an intermediate supply port was provided to supply exposed photosensitive material from the middle. It is extremely difficult to reliably feed the photosensitive material into the supply port of the copying device in the correct posture by groping, and it is unstable and requires skill.

The present invention solves these problems by making it possible to reliably feed exposed sheets of photosensitive material in a stable and correct posture even during darkroom work, and also to function as a developing device. An object of the present invention is to provide a color copying device using a silver halide photosensitive material whose uses are expanded.

[Means to solve the problem]

The purpose of this is to install a manual tray in the mounting position of a magazine that stores the photosensitive material as a long roll in a color copying machine that uses silver halide photosensitive material and has a scanning exposure section, a photosensitive material supplying section, and a development processing section. At the same time, an exposed silver halide photosensitive material sheet is separately placed at a predetermined position on the tray, and the photosensitive material sheet is transported to the development processing section. This is achieved by a color copying apparatus that is controlled in this way and can also be used as a developing device.

The supply roller is driven only to send out the photosensitive material to the first conveyance path 101, and the drive is stopped after the cutter is operated.

The scanning exposure section 3 is arranged at the upper part of the image forming apparatus 1, and scans the original on the document table 2 through the exposure lamp 4 with a reflector and the reflector 5 on the first movable table 4A, and the reflector 6 on the second movable table 6A. .7 and a projection lens 8 to form an image at the exposure position 40. Here, the scanning speed of the first moving table 4A is twice the moving speed of the second moving table 6A, so that the length of the optical path from each scanning position on the document to the exposure position 40 is constant. It is. Also, enlarge the manuscript by 1.5 times or 0

Further, a shutter 17A operated by a solenoid 16A is provided near the exposure position. This shutter 17A is closed except during image exposure scanning to prevent light leakage to the supplying and conveying section 50 of the sensitive material.

The development processing section 24 is placed below the scanning exposure section 3, and is connected to the left sensitive material supplying and conveying section 50 by a connecting conveyance path 105, and the exposed sensitive material to be supplied is transferred to the guide roller 26.2.
7 and is fed into a color developing tank 25. The processing tanks include a bleach-fixing tank 30, a first washing alternative stabilizing tank 31, following the color developing tank 25. The second washing alternative stabilization tanks 32 are arranged in sequence, and the developer and bleach-fix solution are replenished in fixed quantities by pumps from each replenishment tank 47, 48, and during the replenishment, they are mixed with the circulating solution of the processing solution in each processing tank. The 11th and 2nd washing alternative stabilizing liquids are replenished in constant quantities from the replenishment tank 49, and each processing liquid is maintained at a constant level in each tank even though it overflows. That's how it is. Each type has an outer guide frame 36, each of which is provided with driving conveyor rollers 28 at predetermined intervals, and an inner guide frame 37.
A pressure roller 29 is attached that presses against the driving conveyance roller 28, and a conveyance path 38 is formed in each tank by the roller rows of both frames 36, 37 and both rollers 28, 29.

Further, fog exposure in the liquid is applied by the reversal exposure device 42 at the stage when the photosensitive material is conveyed into the first conveyance path in the color developing image tank 25. The device 42 is provided with lamp houses 43, 44, each lamp house is provided with cold cathode tubes 43A, 44A, and the irradiation windows 43B, 44B of the lamp house are provided with color correction filters 43C, 144.
C is generated, and component light corresponding to each type of sensitive material is supplied to the irradiation chamber 45. That is, it is possible to switch between both lamps for irradiation depending on the type of sensitive material. In this way, the photosensitive material being transported is exposed through the exposure window 46 to inverted exposure of light components suitable for each photosensitive material.

The exposed photosensitive material passes through various conveyance paths 38 and is conveyed while being held between conveyance rollers 28 and their pressure rollers 29 provided at predetermined intervals in the conveyance path, and progresses while undergoing a photochemical reaction. , a drying section 35, finishing and recovery.

Each conveying roller 28 for the sensitive material in each processing tank is connected to an AC speed control motor via a drive transmission device that combines a worm, a worm wheel, a spiral gear, and a spur gear. An encoder is directly connected to the AC speed control motor, and the self-generated power is detected by the encoder's tachogenerator and fed back to control the conveyance speed while controlling the current and voltage. Accordingly, the conveying speed in the tank is 4 in/S to 7 mm.

In addition, the exit of the color developing tank, the exit of the bleach-fixing tank, the 11th 2nd
JAM detection sensors are installed at the stabilized seed outlet, the entrance and exit of the drying chamber, so that it is possible to easily determine what to do when a conveyance failure occurs. A liquid level drop detection sensor and a liquid temperature sensor are also provided to maintain appropriate developing conditions.

The structure of each part has been explained above, and the function and operation of the supply conveyance section will be explained using FIG. 2a. In addition, in this embodiment of the copying apparatus, there are three types of sizes A as shown in FIG.
4. It is possible to form images on A3.84 size photosensitive material. And A4 and A3 size are the same 'I'1297
Use a roll of +++m photosensitive material and use a photosensitive material of a different width for 84 size, and the measuring length is 210m+nA for A4 size and 420m for 3 size.
mm%B 4 size is 364mm. However, the present invention is not limited to this, and can of course be adapted to any size.

The tip of the photosensitive material roll 54 in the magazine 53 held between the supply rollers 55 and 56 indicates the number of copies, copy size,
Conveyance of the photosensitive material is started by setting the type of photosensitive material and pressing the copy start instruction button on the operation unit, and the photosensitive material passes through the cutter member 57 and ascends the conveyance path at a speed of 100 mm/s. , conveyance rollers 60.61. It passes through the JAM detection sensor 92 and reaches the position of the photosensitive material size sensor 93, which turns on the photosensitive material size sensor. This corresponds to a distance of 199.5 m + x from the cutter cutting position 57A, and by reading the set size with the button inserted earlier, the difference with the measuring length is 210 - 199.5 = for A4 size.
For IO, 5mm A3 size, 420-199.5 = 2
For 20.5mm 84 size, 364-199.5 = 164
．． 5n++n is sent further.

The timer has a period of 3 + IIS, which is 1 count, and the conveyance speed is 1oOIIl + m/S, which corresponds to 1 pulse of 0.3 mm, so the above counter settings are 10.5 mm 10.3 mm for A4 size = 35 pulses 220.5 mm 10.3 mm for A3 size = 735 pulses For B4 size, 164.5 mm 10.3 mm = 548 pulses.If you drive and stop the pulse motor by directly connecting it to a high-speed clutch and brake until the above pulses have been counted, you can accurately measure each size. made about.

In the second step, the cutter 57 is operated and the measured preceding photosensitive material is cut off from the photosensitive material roll 54 to become a sheet photosensitive material. The remaining photosensitive material roll remains in this state until the clutch for transmitting power from the motor is turned off, stopping feeding and waiting. The sheet photosensitive material is held by each conveyance roller and conveyed upward, and the tip end is placed in a winding stocker. 102, and when the rear end passes the sensitive material sensor 92, the sensor turns OFF, and from this point on, the timer counter indicates 3.
At the 03 count (90.9mm), the high speed clutch connected to the pulse motor is released and the brake is applied at the same time. In this way, the rear end portion stops at a position 90.9 mm ahead of the position of the sensitive material sensor and 20 mm above the exposure position 40. This completes loading before exposure.

At this point, the sheet sensitive material moves to the next exposure process.

In synchronization with the start of the original scanning function of the exposure device, the sheet of photosensitive material is moved 100 shoulders over the conveyance path 101 with the rear end at the beginning by the reverse drive of the motor in order to perform switchback. Reverse feed at a speed of m/s.

In this way, even if the distance between the cutter 57 and the exposure position 40 is short, it is possible to copy a large-sized photosensitive material sheet in a compact space.Furthermore, since the cutter does not operate during image exposure, the photosensitive material can be easily transported. or adversely affect the optical system of the exposure device. Therefore, image exposure is performed by accurately synchronized scanning, and high-quality copies can be obtained.

Synchronization with the exposure device is achieved by starting the optical system's start sensor.
This is done by determining the drive start timing of the transport system based on the N signal. The drive start timing is determined by the copy magnification M, and the timer setting time is 0.4X M.
x 0.2sec.

Then, it is determined whether the exposure is completed or not by measuring the conveyance time of the sheet photosensitive material. It is calculated by: 2.45 ec for A4 size = 3.94 sec for 80θ pulse 7° 84 size = 4.5 for 1313 pulse A3 size
0sec = 1500 pulses are programmed,
After counting these pulses, the high-speed clutch is disengaged and the brakes are applied at the same time.

Naturally, the rear of the sheet photosensitive material at the end of exposure (the top of the sheet at the time of cutting) is 30 mm from the exposure position 40 -2011
111g = Stops after 10mm. The leading end (rear end of the sheet at the time of cutting) passes the first branch point A and is in the first branch conveyance path 103 .

Since the exposure has ended here, the sheet photosensitive material is transferred to the processing section 24.
must be sent to. For this purpose, switchback is performed again, and the first branch conveyance path 103 and the conveyance path 10 are moved with the previous rear end (the leading edge of the sheet at the time of cutting) at the beginning.
Convey roller 60.61.68.69.73.7 inside 1
4 in the opposite direction to the front, switch the drive motor (DC servo motor) to high speed rotation and directly connect the high speed clutch brake to 30
It is transported at a high speed of 0+++ m/s, and the leading end is fed into the hoisting stocker 102, and when the trailing end passes the sensitive material sensor 93, the high speed clutch is activated by the drive motor (DC servo motor) in response to the sensor OFF signal. At the same time as cutting, apply the brake to stop the sheet material. Next, the movable guide plate 66 at the second branch point B is opened in the direction in which the second branch conveyance path is opened by the gate solenoid, and the rear end of the sheet photosensitive material (the rear end of the sheet at the time of cutting) is placed at the front. When the leading edge reaches 33.5 mm after passing the sensor 95 in front of the automatic processing machine, the high speed conveyance of 300 mm/S is started from 4 mrtr/S to 7 mrtr/S depending on the type of photosensitive material. Switching to a low-speed conveyance arbitrarily set within the range of mm/S, each conveyance roller 28.
29 is also 4mm by the speed control motor that drives the processing section.
Since it is driven in synchronization with the speed of 7 mm/S to 7 mm/S, the transfer is smooth. When the rear end of the sheet photosensitive material passes the processor front sensor 95, the sensor
FF, and at this point one copying process is completed, and this signal turns on the clutch to the supply roller 55, making the next copying possible.

4m from 300mm/S at the entrance of the automatic processing machine from the start of the next copy
It takes about 11 seconds until the next head reaches the speed down position from m/S to 7 m+++/S, so the trailing edge of the sheet photosensitive material one page before is fed at a speed of 4 mm/S to 7 mm/S. Because there is, it is ahead by 44mm to 77mm,
The spacing in the treatment tank is 44-33.5 = 0.5 to 77
-33.5=43.5mm.

In this way, the photosensitive material supplying and conveying section 50 of the copying apparatus of this embodiment
A measured switchback path for the sheet sensitive material is provided in the sensitive material path between the cutter part 57 and the exposure position 40, and a switchback path is provided in the sensitive material path between the exposure position 40 and the processing section 24. Two back paths are provided, allowing for smooth conveyance, measurement, cutting, and exposure, and delivery to the processing section. However, it is needless to say that it is not necessary to limit the switchback route to two locations, and it is possible to use one switchback route. In order to reduce the space and use a small number of members, it is advantageous to use two locations.

In order to make large-sized copies by utilizing the transport path in a small space as described above, the transport path is switched back and used for both the forward and return paths.

However, since the photosensitive material is conveyed over a long distance, including both the forward and return trips, it takes time. Therefore, it is desirable to transport the material at as high a speed as possible. However, since it is particularly important to improve the accuracy of the conveyance of the sensitive material sheet for measurement and image exposure, it is necessary to avoid excessively high conveyance speeds during this process. However, since there are not many restrictions on precision in the next step, which is transport from the end of image exposure to the processing device 24, it was decided to transport at a fairly high speed. The conveyance speed of the photosensitive material within the processing device such as development is set according to the photochemical properties of each photosensitive material. The speed is considerably lower than the conveyance speed until reaching the target.

Either the sheets of light-sensitive material are conveyed in the processing device 24 in a continuous manner with their leading and trailing ends almost in contact with each other without overlapping, while maintaining a constant interval, If too much time is spent on transport for image exposure and further transport until the tip reaches the processing device 24, the orderly flow of transport as described above cannot be obtained, and the processing device 2
As the distance between the photosensitive material sheets in the photosensitive material sheet 4 increases, the number of sheets processed per unit time decreases, resulting in a decrease in processing capacity and processing efficiency.

Therefore, in order to convey the photosensitive material sheet efficiently without reducing the throughput, the conveyance speed is changed to an appropriate speed at each stage in the copying machine, as described above.
To complete transportation within the required time easily, rationally, and efficiently.

Also, during transportation (when this JAN occurs, the first JAM
Detection sensor 92, sensitive material size sensor 93, second J
AM detection detection sensor 94 sensor ON at each time,
It is determined whether the conveyance of the sheet photosensitive material is normal or abnormal based on the combination of OFF and OFF, and when an abnormality occurs, the abnormal location of the machine is indicated so that it can be easily dealt with.

In addition, the magazine 53 of this supply conveyance section has a
As shown in the figure, a system of identification circuits has been adopted to clearly distinguish the type of photosensitive material (for example, whether it is a reflective photosensitive material or a transparent photosensitive material) or roll width, and to make scanning easier. Each dedicated magazine has a unique cam protrusion 11
0 is provided, the protrusion is detected by the sensor 114, and the protrusion is automatically connected to the identified circuit so that switching can be performed to correspond to each unique inversion exposure amount. In order to accurately identify the magazine and to convey the valley-width-sized photosensitive material while accurately regulating its position in the width direction, it is necessary that each magazine be accurately set at the reference position. Therefore, each magazine is provided with a regulation pin 121, and this pin is guided by a regulation rail 120 provided on the pedestal 118 for loading, so that the positioning of the magazine is maintained accurately.

The photosensitive material drawer portion 115 of the magazine 58 containing the photosensitive material roll 54 has a lip shape, and this portion is pushed into the supply roller 55, 56 as shown in FIGS. 4, 5, and 6. When the device is closed, the rollers 55 and 56 enter the window 116 formed in the lip of the drawer portion 115, so that the photosensitive material can be immediately pulled out at the time of activation. At this time, the supply roller 55
．． Resin rollers 55a, 5 whose outer diameter is slightly larger than that of 56.
6a are provided at both ends of each shaft, and the lip-shaped drawer portion 115 of the magazine is guided by this resin roller, so that the photosensitive material supply rollers 55 and 56 are not scratched. .

When the rollers touch the window 116, the rollers 55 and 56 are in contact with each other, but the rollers 55a and 156a are shifted in position as shown in FIGS. 5 and 6 so that they do not come into contact with each other. By setting the magazine on the mounting base 118 of the supply conveyance section 50 in this manner, preparation for activation can be completed with a single touch.

Further, when it is desired to process a small amount of these various sizes, image exposure is performed using an exposure device such as another printer, and the exposed photosensitive material is transferred to the mounting table 118 of the magazine 53 of the copying apparatus of the present invention. The copying machine is made to function as a developing device by reinstalling the manual tray 153 instead of the magazine into the loading opening of the copying machine and performing only the developing process.

That is, the cover 52 is opened and the manual tray 153 is installed in place of the magazine 53 as shown in FIG.

As shown in FIGS. 7 and 8, the manual tray 153 is provided with symmetrical guide plates 155 on both sides of the base member 154 and an upper ceiling guide 157, and has a window at the tip 115 like the tip of the magazine 53. 116 is provided, and the supply rollers 55 and 56 of the photosensitive material supply and conveyance section of the copying machine are guarded by the guard rollers 55a and 56a so that when the tray is installed, it can be set by jumping into the window 116 without any hindrance. . In reality, when the tray is mounted along the guide rail 120 of the mounting table 118 while pushing down the lock lever 158 against the torque spring 161, the tip of the lever reaches the position where the supply roller jumps into the window 116. The claw portion 159 is locked and positioned by engaging the fixed position 118a of the mounting base 118.

After the manual tray 153 is mounted in this manner, a sheet of photosensitive material that has been exposed using a separate device is placed on the tray, and the leading end of the sheet of photosensitive material is placed on the feeding roller 55, 56.
Press it against the contact part of the

In addition, as shown in Figures 4 and 5, there is a mark provided at the bottom of the manual tray to distinguish between transparent photosensitive material (travel pen film) and reflective photosensitive material (photographic paper), or to distinguish sensitivity. If the protrusion 110 as an identification mark is set in accordance with the photosensitive material used, it will be detected by the detector 114 provided on the mounting base 11g under the same conditions as when the magazine 53 is mounted.

Then, the detected information is sent to the control device of the color copying apparatus, and operation is performed under developing conditions suitable for the photosensitive material used.

Further, a guide pin 121 similar to that of a magazine is provided on the back surface of the manual tray, and the tray is guided by a guide rail 120 provided on the mounting base 118 so that the tray can be easily mounted.

In this way, the manual tray 153 is attached to the mounting base 1 of the copying machine main body.
18, the operator can easily and correctly guide and insert the image-exposed photosensitive material along the left and right guides 155 of the tray, the upper ceiling guide 157, and the base surface 154A, even in the dark, and place the image-exposed photosensitive material on the supply roller. 55.5
In addition, the hand tray can be loaded and placed in position 6, and the hand tray can be adjusted to accommodate each size of photosensitive material by adjusting the side guide, and there is an independent hand tray that corresponds to each size of photosensitive material. You can prepare a tray, but the former is preferable. It is also possible to accommodate a plurality of exposed photosensitive materials by storing them in a light-shielding cassette, but the tray of this embodiment is sufficient for expedited processing.

Further, when the magazine 53 is installed, the detector 114 detects a protrusion dedicated to the magazine provided on the magazine, and the detection signal detects scanning exposure, supply/conveyance/cutting, development processing,
Each process of the drying process is controlled so that the normal sequence for a rolled sensitive material in a magazine works, and conversely, when the manual tray 153 is attached, the tray-specific protrusion 110 provided on the tray is detected by the detection 6114. As a result, the scanning exposure process is stopped by the detection signal.
When the photosensitive material is conveyed from the conveyance path 101 to the stocker, the conveyance path 101 and the second branch conveyance path 104 are connected by the operation of the movable guide plate 66, and the photosensitive material enters the conveyance path 104 by the switch pack and is different from the normal state. In a process in which switchback is omitted twice, the rear photosensitive material that has not reached the developer loading port is directed directly to the connecting conveyance path 105 of the developer section. The sensitive material conveying rollers 73, 74, 68, 69.
85.86 at an arbitrarily set conveyance speed between 100 mm/sec and 300 mm/sec, and the timing is set after the leading edge is detected by the automatic processing machine front sensor 95, at a conveyance speed of 4 to 7 mm/sec. The low speed conveyance is maintained until the trailing edge passes the sensor. Further, by detecting the rear end, a signal indicating that the next photosensitive material can be fed is generated. In this way, it is possible to directly and smoothly feed a specially sized exposed light-sensitive material sheet to the developing section. Also, in this case, the paper size detection sensor on the conveyance path is used as a JAN detection sensor.

Note that when the manual tray is attached, the exposure light cutting means is a shutter 1 for blocking light from entering the exposure position 40.
This can be done by activating the light source lamp 7A or by turning off the light source lamp 4, but in this embodiment, both are controlled to be used together.

It should be noted that when handling such an exposed photosensitive material, although the explanation in this embodiment is based on the assumption that it will be operated in a dark room, the cover 52
It is possible to significantly reduce the need for darkroom operations by providing a tent-like light-shielding space made of black velvet film above.

〔Effect of the invention〕
