Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a color copying apparatus that uses a silver halide photosensitive material (hereinafter simply referred to as photosensitive material) and performs copying through photographic processing. Regarding.

[Conventional technology]

In recent years, there has been an increasing demand for color copies.
Although color electronic copying devices are on the market, their image quality is insufficient and it cannot be said that they fully satisfy the demand for color copying.

Color copying devices using photosensitive materials have also been proposed and are now on the market.

Color copying using photosensitive materials is not only superior in image quality, but also has the following advantages. In other words, it is possible to obtain extremely excellent not only reflective copying in which an image is formed on white paper, but also excellent transparent copying in which an image is formed on a transparent film and the image is viewed using transmitted light. Color images produced by electrophotography have poor light transmittance because the toner forming the image is mainly composed of resin, and it is essentially difficult to obtain high-quality transmission images.

Copying devices using such photosensitive materials can produce copied images that are far superior to electrophotography in terms of photographic properties such as image sharpness, gradation, color reproducibility, tone, and brightness.

[Problem that the invention seeks to solve]

Copying apparatuses using photosensitive materials can produce high-quality copied images, provided that appropriate exposure and development processes that take full advantage of the excellent photographic properties of the photosensitive material are obtained. In addition, a variety of sensitive materials are available with special characteristics in terms of sensitivity, color temperature, and gradation, and they must be used depending on the purpose. Furthermore, there is a problem that even sensitive materials having the same characteristics have individual variations, and unless appropriate measures are taken to compensate for these variations, satisfactory copying image quality cannot be obtained.

The object of the present invention is to solve these problems and provide a color copying apparatus that can produce stable high-quality copies.

Three types of light beams 44C2 and 44C are provided, and component light corresponding to each type of sensitive material is supplied to the irradiation chamber 45. In other words, as mentioned above, photosensitive material 1! Depending on the identification of the machine's display member, each of the two lamps can be turned on, or both lamps can be turned on and switched, and each color temperature conversion filter can also be switched as necessary for irradiation.

A liquid level drop detection sensor and a liquid temperature sensor are also provided to maintain appropriate developing conditions.

The configuration of each part has been explained above, but 8! of the supply conveyance section!
The function and action will be explained using Fig. 2.

In addition, in this embodiment of the image forming apparatus, three
It is possible to form images on sensitive materials of various sizes A4 and A3.84. And A4 and A3 are 84P'! using the same width 2971N photosensitive material rolls! A different width of photosensitive material is used, and the length of the measuring tape is 210mz for A4 size.
3 size is 420■, B 4 i! lj is on the 3641 shoulder. However, it goes without saying that the present invention is not limited to this, and can be applied to any size.

The forward end of the photosensitive material roll 54 in the magnon 53 held by the supply rollers 55 and 56 is used to control the number of copies, copy size, photosensitive material type M settings, and input of the copy start instruction button. The command transmission means starts conveying the photosensitive material, passes through the cutter part 57, ascends the conveying path at a speed of 100 zz/s, and then starts conveying the photosensitive material by the conveying rollers 60, 61 and the JAM detection sensor 9.
2 and reaches the position of the photosensitive material size sensor 93, and the photosensitive material size sensor is turned on. This is cutter cutting position 5
At a distance of 199.5zz from 7A, read the set size using the button inserted earlier and find the difference from the length of the measuring tape, 210-199.5 = 1 for A4 size.
For 0.5 shoulder lΔ3 size, 420-199.5 = 220.
5zzB 41! If ll, 364-199.5 = 16
Only the 4.5z shoulder should be pushed further.

The timer counts 1 at a cycle of 311S, and the conveyance speed is 1.
Since it is 00jz/S, it corresponds to 1 pulse 0.3in+, so the above Kawatar setting value is A 4 t, q: 10.5 t, 110.3 JI scrap = 35
Pulse A3 size: 220.5z summer / 0.3xz = 7
164.511/0.311 for 35 pulse 84 format
= 548 pulses, and by directly connecting the pulse motor to a high-speed clutch and brake and driving and stopping the pulse motor until the above-mentioned pulses have been counted, accurate measurements can be made for each size.

Here, 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, and the clutch that transmits power from the motor is turned off, stopping feeding and waiting.
The sheet of photosensitive material is conveyed upward while being pinched by each conveyance roller, and the leading edge is rolled up into the winding stocker 102. When the trailing edge passes the photosensitive material sensor 92, the sensor is turned off, and from this point on, the timer is activated. When the counter reaches 303 counts) (90,9zz), 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 zm ahead of the position of the sensitive material sensor and 20 ax above the exposure section 40 . This completes loading before exposure. At this point, the sheet photosensitive material is transferred to the next exposure process. In synchronization with the start of the original scanning function of the image exposure section, the sheet photosensitive material is reversely transported on the conveying path 101 at a speed of 100 zz/s by the reverse drive of the motor in order to perform switchback.

Synchronization with the exposure device is performed using the 0 of the start sensor of the optical system.
This is done by determining the drive start timing of the transport system based on the number N (i).The drive start timing is determined by the copying magnification M for a timer setting time of 0.4X M
Set by X O, 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 2.4 seconds for A4 size” soo Hals B44
! 11, 3.94 seconds = 1313 pulses, A3 size, 4.50 seconds = 1500 Hals is programmed, and when these pulses are applied, the high speed clutch is disengaged and the brakes are activated at the same time. Naturally, the rear part of the sheet photosensitive material at the end of exposure stops at a position 3011-20ax=1 (ha) past the exposure position 40.The leading end passes the first branch point A and is in the pt41 branch conveyance path 103.

Since the exposure has now been completed, the sheet photosensitive material must be sent to the development processing section 24. To do this, we made a switchback again and placed the rear end of the car in the first position.
The conveyance roller 6 moves through the branch conveyance path 103 and the conveyance path 101.
0, 61, 68, 69, 73.74 in the opposite direction to the front, the drive motor (DC servo motor) is switched to high speed rotation, the high speed clutch brake is directly connected, and the first part is transported at a high speed of 300zz/S. When the rear end of the sheet of photosensitive material fed into the stocker 102 passes the sensor 93, the high-speed clutch is disconnected from the drive motor (DC servo motor) in response to the sensor OFF signal, and at the same time, the brake is applied to stop the sheet of photosensitive material. let

300zz/S with the rear end of the sheet photosensitive material at the beginning, move the receptacle plate 66 at the second branch point B in the direction in which the second branch conveyance path is opened by the date and time maid. High-speed conveyance is started, and when the leading edge passes through the sensor 95 in front of the automatic processing machine and reaches 33.5zz, the high-speed conveyance of 300za+/S is changed to 4 depending on the type of photosensitive material.
Switching from zz/S to a low speed conveyance arbitrarily set in the range of 77131/S, the color development 29 from the connecting conveyance path 105 is also synchronized to the speed from 4zz/S to 711/S by the speed control motor that drives the processing section. Since the machine is driven by the machine, the delivery is smooth.

Then, when the rear end of the sheet photosensitive material passes the processor front sensor 95, the sensor is turned OFF and one copying process is completed at this point, and this signal turns on the clutch to the supply roller 55 and the next copying process is completed. Copying becomes possible.

o When a sheet photosensitive material is conveyed abnormally with the OFF combination, the abnormal location of the 8!1 machine is indicated so that it can be easily dealt with. Also, in the magazine 53 of this supply conveyance section,
As shown in Figures 4 and 5, an identification circuit system has been adopted to clearly distinguish the types of photosensitive materials and roll widths, and to make scanning easier.
A cam protrusion 110 is provided at a common specific position on the 1' non-stick 53 as a display member for identification.
There are provided n protrusion setting areas A, , A2, . Then, 1 to n protrusions are set in the setting area, and the combination of the protrusions set as a display member for identification is as shown in the following equation.

nC, +nC2+-=--+nCn-1+nCn, that is,
3 types when n=2, 7 types when n=3') n=4
In this case, 15 types of identification are possible.

Therefore, when n=2, there are a maximum of 3 types, when n=3, a maximum of 7 types, when n=4, a maximum of 15 types, and when n=5, a maximum of 31 types! ! Special magazines can be identified for photosensitive materials with different Iwt performance.

In addition, a margin 1g1U ground detection center part 114 as shown in FIG. 4 is provided on the pedestal 121 of the photosensitive material supplying and conveying section 50 of the image forming apparatus 1 corresponding to each of the n+ projection setting areas. . Although the center can be a photoelectric switch, a magnetic switch, a microswitch, etc., a microswitch is used in this embodiment. That is, the sensor part 11
4 is A Iy A 2 r of magazine 53...
・alla2t corresponding to each protrusion setting area of tAn...
..., an microswitch is provided.

When this microswitch catches the protrusion of the magazine to which it is attached, for example, in the case of n=3, one of the seven combinations of signals shown in Figure 7 is generated, giving the impression that the magazine has been stored. The material specific signal enters the control device fi130 as shown in the circuit diagram of FIG. Speed conversion signal 130A of motor M8, speed conversion signal 130B of processing liquid replenishment pump drive motor M9, exposure amount switching signal 130C of cold cathode tubes 43A and 44A of reversing exposure device 42 due to alpha lamp switching, and color temperature circuit switching signal 130
D, all or part of the conversion command signal 130E of the image exposure lens aperture 12A1 and the filter 14A is transmitted.

Incidentally, the conversion of the exposure amount is carried out by using two cold cathode tubes, when each cold cathode tube is turned on, when both are turned on, and by means of changing the voltage supplied to each cold cathode tube.

In addition, three types of color temperature conversion filters are placed in each cold cathode tube.
It is designed so that it can be switched depending on the sensitive material characteristic information.

As a result, the distinction between a transparent positive type such as an OHP and a normal reflective positive type, and the unique photographic characteristics of each photosensitive material are correctly transmitted to the control device 130 as the photosensitive material type confirmation signal 114B, and the appropriate processing conditions are switched. The copying machine operates.

At n=2, it is only possible to distinguish between a transparent positive type and a reflective positive type, but as n=3+n=4, appropriate processing conditions for various types of photosensitive materials with fine photographic characteristics can be accurately identified. It becomes like this. That is, although photographic characteristics of photosensitive materials are not necessarily the same and vary among manufacturing lofts, it is possible to correct this variation by using this display member.

Further, since the A N B t'l is distinguished by the width dimension of the photosensitive material roll, if this characteristic is displayed on the magazine, it can be effectively utilized for controlling the image forming size.

Incidentally, no magazine is provided that does not have one of the protrusions displayed.

Therefore, when all the sensors are OFF, it means that the magazine, that is, the photosensitive material is not mounted on the pedestal 121 of the conveying section 50.

As in this embodiment, a cam protrusion and a microswitch are used as the identification display means, but instead, a unique bar code is affixed to a specific location on the magazine, that is, for each magazine, that is, for each photosensitive material characteristic, and this is read using a bar code reader. It is also possible to read it. However, in consideration of cost and illumination density, this embodiment is considered to be more advantageous.

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 bin is provided with a regulation pin 121, and this bin is connected to the regulation rail 1 provided on the pedestal 118.
Since the magazine is loaded while being guided by the magazine 20, the positioning of the magazine is maintained accurately.

The photosensitive material drawer portion 115 of the magazine 53 containing the photosensitive material roll 54 has a lip shape, and this portion is shown in FIG.
When it is inserted into the supply roller 55, 56 as shown in Fig. t55 and Fig. 6, the roller 55, 56 enters the window 116 made in the lip of the drawer section 115, so that the photosensitive material can be immediately drawn out at the time of startup. It is. At this time, the υI fat crawler 55 has a larger outer diameter than the supply roller 55, 56.
A56a is provided at both ends of each shaft, and this resin roller touches and guides the lip-shaped pull-out portion 115 of the magazine, so that the photosensitive material supply rollers 55 and 56 are not scratched. It is. After each roller reaches gl16, rollers 55 and 56 come into contact with each other, but rollers 55a and 56
A is shifted in position as shown in FIGS. 5 and 6 so as not to contact each other. On top of this, the sea urchin feeds the non-conveying section 50
By setting it on the pedestal 118, preparations for starting can be completed in one click.

The above describes a case in which characteristic information of various photosensitive materials is stored in labels on magazines, and the copying machine reads the stored photosensitive material information and automatically makes appropriate corrections. The same appropriate correction can be made by manually inputting the characteristic data recorded on the wrapping paper of the photosensitive material into the numeric keypad provided in the operation section of the copying machine and shown by the dotted line in the circuit diagram of Fig. 8, without storing the characteristic data in the magazine. This is so that it can be obtained.

〔Effect of the invention〕

The color copying apparatus of the present invention makes it possible to reflect the characteristic data of the sensitive material on the exposure amount and color temperature of the reversal exposure, so that the reversal exposure factor alone or other factors such as development speed, image exposure, etc. It is now possible to obtain high-quality copies with appropriate color tone and gradation by reflecting the images.
