DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a color image recording apparatus for obtaining a color 7% copy from a color still image signal.

[Prior art]

Various color printers have been proposed for producing hard copies of color reproduced still images obtained from television receivers, video recorders, video disc players, etc., but all of them are expensive and have unsatisfactory image quality. It wasn't.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a color image recording device that can be realized at low cost and has satisfactory image quality.

[Structure of the invention]

For this purpose, the color image recording apparatus of the present invention includes a feeding section that feeds the color photosensitive material, and an exposure means that exposes the color photosensitive material conveyed from the feeding section by emitting light based on a color still image signal. , comprising an automatic development processing section and a conveyance system for subsequently conveying the exposed photosensitive material to the entrance of the automatic development processing section, and the automatic development processing section develops and bleaches the photosensitive material conveyed to the entrance.

In the figure, Y is a printer section of the image recording apparatus, Z is an automatic development processing section, and CRTD is a video image display section that can display a desired color image as a still image. X is a signal processing section, which may be built in the printer section Y.

In the figure, a sheet of silver halide color photosensitive material photographic paper (hereinafter referred to as photographic paper) as a photosensitive material stored in a supply magazine 73 is exposed to light based on a color image signal by FOT, which is an exposure means. The toner is conveyed to the entrance ε of the automatic development processing section Z via the U-turn guide RO of the RO and the S-shaped side RO2. The transported photographic paper is

During a series of operations, that is, when the device is normal and recording is being performed, the photographic paper is automatically transported from the supply magnon to the transport exit 309, and the upper part of the drying rack 307 is used to check the transport status. Although it may have a partially transparent structure, for insects whose stabilization treatment is completed in the rinsing tank from the supplied magnon, the photographic paper is constructed so as to be shielded from light other than the necessary exposure light, especially light from the outside.

Therefore, the operator must set the photographic paper and use the attached CRTD.
Display the video signal as a still image, select the desired still image, turn on the appropriate switch, and a series of operations will be carried out to produce a color hard print of the desired image on the photographic paper. It is something that can be done. Of course, once the exposure operation has started, the CRTD may be able to change the display contents in order to select the next desired still image.

The mechanical configuration and operation of this image recording apparatus will be described in detail below.

71.71' is an outer box that shields the inside from outside light, 72
is a pedestal (rail), and a removable supply magnon 73 is mounted on this pedestal 72.

This supplying machine 73 is provided with a lid 75 that closes an opening 74, and a push plate 77 that applies pressure to the loaded color photographic paper in response to the elastic force of a spring 76 is provided inside. The color photographic paper 6 is loaded with its photosensitive surface facing downward (towards the opening 74). Reference numeral 78 is a cutting board for preventing two or more sheets of color photographic paper 6 from coming out at the same time. 79 is a microswitch that detects the open state of the shutter 78. Also, 98
is a presser roller that presses down the color photographic paper, and since the color photographic paper bends at this portion, it improves the smoothness and reduces the stroke of the suction cup, which will be described later.

80 is a take-out device for taking out the color photographic paper 6;
The front view is shown in the figure. Pins 82 are engaged with L-shaped guide holes 81a formed on both sides of the frame plate 81, and a suction cup mounting body 83 is installed between the bins 82 on both sides.

The above-mentioned paper presence/absence sensor 59 is attached using the suction cup attachment body, and two suction cups 85 are attached so that an upward elastic force is applied by a spring 84. Further, the interior of the suction cup attachment body 85 communicates with a check valve 87 via a hose 86. 87a
is a protrusion that opens the check valve 87 when pushed. This suction cup mounting body 83 is connected to the upright side 90a of the slide plate 90 via two arms 88 and 89 on both sides thereof. A roller 91 is provided on the slide plate 90, and is engaged with an elongated hole 81b formed on the lower side of the frame plate 81. Note that a protrusion 81d is provided on a rising side 81c at the tip of the frame plate 81, with which a protrusion 87a of the check valve 87 comes into contact. The paper feed motor 56 has a built-in deceleration mechanism and is fixed to the frame plate 81 via a pedestal 92.
A disk 93 is fixed to the output shaft 56a, and this disk 9
An arm 94 is pivotally supported on the outer periphery of 3, and this arm 94 is pivotally supported on a bottle 95 implanted in the slide plate 90.

In this take-out device 80, a slide plate 90 connected by an arm 94 reciprocates once in the direction of arrow C every time the paper feed motor 56 rotates and the disk 93 rotates once.

Also, during this reciprocation, the suction cup mounting body 83
The movement is received through the arms 88 and 89, so it is guided by the id hole 81a and reciprocates once in the direction of arrow F, that is, in an L-shape in the up-down and back-and-forth directions. Then, the suction cup 85 is the first
When the check valve 87 returns to the state shown in the figure, that is, to the lowermost position, the protrusion 87a of the check valve 87 comes into contact with the protrusion 81d, and the inside communicates with the atmosphere. The rotational position of the paper feed motor 56 at this time is defined as the home position.

Therefore, in this take-out device 80, when the suction cup 85 rises to the highest position, it comes into contact with the color photographic paper 6 from the open lower part 4 of the supply magazine 73, and is pushed up and deformed by the suction cup 85, causing the air inside the suction cup 85 to is discharged from the check valve 87, and the color photographic paper 6 is sucked under negative pressure. When the suction cup 85 moves downward, the color photographic paper 6 is separated by the cutting board 78 and only one sheet is taken out. When the suction cup 85 descends to the lowest position, it moves forward and the protrusion 87 of the check valve 87
a comes into contact with the protrusion 81d, air enters the check valve 87 from the outside, the negative pressure suction in the suction cup 85 is released, and the force→- photographic paper is peeled off from the suction plate 85.

In this way, one sheet of color photographic paper is fed each time the suction cup 85 moves back and forth.

Reference numeral 96 denotes a paper feed roller, which further feeds the color photographic paper 6 that has been sucked and taken out by the take-out device 80, and is circulated by the output of the conveyance motor 57 (not shown in FIG. 1). It has become. A paper feed sensor 60 is provided at the exit of the paper feed roller 96, and detects whether or not color photographic paper has bitten into the paper feed roller 96. 97
is a guide plate that guides the conveyance of color photographic paper.

A FOT 1 is provided below this guide plate 97. Reference numeral 101 denotes a push plate for pressing the color photographic paper into close contact with the front surface 102 of the FOT 1, and receives the elastic force of a spring 103.

104 is a conveyance roller, which is used to convey the color photographic paper accurately on the front side of FOT 1, and is connected to the conveyance motor 5.
It rotates in response to the output of 7. and,
A paper discharge sensor 61 is provided below this conveyance roller 104 .

The photographic paper that has passed the paper discharge sensor 61 is conveyed to the entrance ε of the automatic development processing section Z through the id R○1→RO2 of the conveyance path RO by rotating roller pairs 110a, 110b, 110c, and 110d. It is desirable that the distance between the roller pairs be smaller than the length of the photographic paper. The photographic paper sent from the printer section Y is inserted through the entrance ε, is held by a group of rotating feed rollers, moves downward, and is transferred to the developer tank 3.
Transported to 02. In FIG. 1, the dash-dotted line indicates the transport path of photographic paper. Above the developer 302, there is a photographic paper receiving row 2302A and a feeding/discharging acid squeezing roller 30.
2B, and a plurality of idle rollers 302C are rotationally driven in the developer tank 302. The photographic paper is moved while being held by these rows 2302A, 302B, and 302C, is immersed in the developer solution contained in the tank, and is developed during the movement for a certain period of time, after which it is transferred to the next bleach-fix tank. It is transported to 303.

The bleach-fixing unit 303 includes a roller 303A for receiving and feeding photographic paper, and a guide roller 303C, and the photographic paper subjected to the development process is transferred to the fixing solution F in this bleach-fixing tank.
is fixed and conveyed by.

The photographic paper that has undergone the above development and fixing process is then rinsed in the first rinse tank 304. Rinse second tank 305. Rinse tank 3
Guided to 06. These stabilizing tanks contain water wash W or a stabilizing solution, and by passing the photographic paper immersed in each tank, the bleach-fixing solution F is washed away and a stabilized image is obtained. The photographic paper that has undergone the stabilization process is squeezed and sent out by the final roller 306A, and is conveyed along the side plate and sent to the next drying chamber 307.

Inside the drying chamber, there is a group of transport rollers that clamp and transport the photographic paper that has undergone stabilization. After the stabilization process, the wet photographic paper is transported and passed through the drying chamber, where it is dried by a stream of warm air.

In the drying rack, outside air is blown into the heater section H by an air blower 112, so that hot air is sent to the photographic paper passing above to dry it.

The photographic paper that has passed through the drying chamber 307 is transported to the exit 3.
09 to the outside, placed on the pedestal 313,
Terminate the process.

Each time the photographic paper is processed, the components of each of these processing liquids are consumed and changed, resulting in a so-called fatigue state and a decline in processing capacity. I can't do two things.

To deal with these problems, the automatic development processing section usually includes a replenisher tank 310 that stores replenisher for each processing solution.
is attached in or near the main body, and the replenishment pump 311
The capacity of the processing solution in each processing tank is always kept constant by replenishing an appropriate amount of replenishing solution one after another according to the amount of photosensitive material processed (sometimes due to the blackened area of the photosensitive material after development). Let's do it.

It is necessary to always replenish the correct amount of fluid.
Based on a replenishment amount strictly determined in advance through preliminary experiments, etc., the replenisher is sent from the replenisher tank 10 to the processing tank by a high-precision liquid sending means such as a metering pump or a magnet pump.

In addition to the above, a bellows pump, a straining roller pump, a cylinder pump, or the like can be used as the replenishment pump. When using these pumps in an automatic development processing section, these pumps are relatively large and heavy;
Also, for reasons such as external design and operability, it is installed inside the main body of the automatic processing apparatus, relatively lower.

FIG. 4 is a block diagram showing the entire path of the color video signal and control signal of the image recording apparatus of this embodiment, and this apparatus is composed of a signal processing section X and a printer section Y. The signal processing section It is composed of In addition, the printer section Y sends a drive signal to the FOTl described above, a paper feed motor 56 which is a synchronous motor for feeding color photographic paper, a transport motor 57 which is a pulse motor for transporting color photographic paper, and the motors. A drive circuit 58, a non-contact type paper presence/absence sensor 59 such as an optical reflection type that detects whether or not color photographic paper is in the supply magazine, and a paper presence/absence sensor 59 that detects whether or not color photographic paper has bitten into the paper feed roller. It is composed of a non-contact paper feed sensor 60, a non-contact paper ejection sensor 61 that detects whether color photographic paper is ejected, an amplifier group 62 that amplifies the sensor signal, and a pan 7a 63. .

Next, the printer section of the image recording apparatus according to the embodiment, particularly the video signal processing, will be described in detail. FIG. 4 shows a schematic configuration of the video signal processing section. This video signal processing section is
Input NTSC color image RGB signals to display RG
a signal input unit I that samples pixel signals of each color of B;
The A/D converter ■ converts the sampled signal into a digital signal, the digital signal processor ■ performs gamma correction to fill in the scanning line spacing to make it less noticeable, and match the sensitivity of the photosensitive material, etc., and the digital signal The device is comprised of a D/A converter (2) which converts the image into an analog signal, and an exposure unit (V) which exposes the color photosensitive material and corrects unevenness in the amount of light at that time.

■J1 optical blank L wide - Exposure section ■ uses color photographic paper (for example, γ = 2.5) as a photosensitive material, and this color mark 1iUii1fc
In addition, a method was adopted in which the scanning surface of a fiber optics tube type CRT (hereinafter referred to as FOT), which scans primary colors in accordance with color image signals, is brought into close contact with the scanner and the color photographic paper is exposed to light.

Figures 5 and 6 are for explaining the exposed part. FOTI has red phosphor (for example, P22-RE3) 2 and white phosphor (for example, P4) on the surface scanned by the electron beam. Optical fiber group 4 is installed in front of the phosphor 2.3, and optical fiber group 4 is installed in front of the phosphor 2.3.
Three types of color filters 5r (red), 5g (green) on the front of the
, sb (blue) are arranged side by side. White phosphor 3 is used for the green and blue color filters 5g and 5b, and this is not used for the red color filter 5r, but a different red phosphor 2 is used. This is suitable when the red sensitivity characteristic of the color photographic paper 6 used is in a long wavelength range and it is difficult to obtain a high density.

The color photographic paper 6 is exposed to primary colors while being conveyed in the direction of arrow A in close contact with the color filters 5r, 5g, and 5b.

rs gSb in figure W&6 is the recording scanning line on the front side of this FOTI, and the pitch of the recording scanning ir and g is Q.
rg, and the pitch of recording scanning lines g and b is Q gb.

(2) - Unevenness In F'OT 1 with uJEr, fine light intensity unevenness occurs due to uneven coating of the phosphor 2.3 or variation in optical loss of the fiber 4. If there is unevenness in the amount of light along the same recording scanning line, vertical streaks will appear along the conveyance direction of the color photographic paper, and the image quality will deteriorate severely.

Therefore, as a countermeasure against this unevenness in light amount, conventional methods have been to use a multiple exposure method to average the light amount and erase it, or to measure the light amount for each pixel in the recording scanning line direction and to make corrections by multiplying the input by the reciprocal of the light amount. is proposed.

However, the former requires signal processing such as scanning line interpolation to fill in the spaces between the recording scan lines, which will be described later. It has the disadvantage of being invalid.

Therefore, in the present invention, paying attention to the fact that fine light intensity unevenness occurs randomly on the FOT tube surface, it was decided to slightly move the horizontal recording scanning position in the vertical direction for each -horizontal scan. As a result, unevenness in the amount of light appears randomly on the color photographic paper, so it is possible to eliminate vertical streaks that appear in the conveyance direction of the color photographic paper.

However, if you simply adopt this method and move the horizontal recording scanning position randomly in the vertical direction, the synchronization with the conveyance of the color photographic paper will be lost, and the same line will not be able to be exposed accurately for RGB, resulting in poor image quality. to degrade. Therefore, the problem can be solved by keeping the conveyance speed of the color photographic paper 6 constant and adjusting the vertical deflection amount and the recording timing.

Figure PJJ7 is a diagram showing the timing. When the recording scanning line position is moved in the opposite direction to the conveying direction of the color photographic paper for each horizontal scan, the interval between the scanning lines recorded on the color photographic paper is: D, = S, 132... (1
). Here, S2, the conveyance pitch of the color photographic paper per horizontal scan, is the amount of displacement of the recording scanning line in the vertical direction (conveyance direction). Conversely, when moving the recording scanning line position in the same direction as the color photographic paper conveyance direction,
The movement is performed every horizontal scan in the same way as above, but the exposure is paused every other horizontal scan so that no recording is performed. Therefore, the gap D2 between recording scanning lines at this time is D2=2 (S, +82)...
・(2) becomes. Then, to prevent uneven conveyance,
That is, in order for the same recording scanning line to be exposed in each RGB color, it is necessary that D, = D2 = D (3), and the condition is S, = 332
, (4). For example, if S=87μ-, then 52=29μm.

Figure 8(a) shows the still image reproduced on the TV screen 7.
Further, FIG. 8(b) schematically shows the state in which the still image is printed on the color photographic paper 6 by the FOT 1. The horizontal scanning period of an NTSC television signal is 63.5 μs, and each scanning line has a horizontal scanning period of 640 μs.
If you try to sample pixels in the normal way, A/
A total of three D converters (3) are required for R, G, and B, each having a conversion speed of about 12 MHz. Furthermore, even if the conversion is performed at this speed, the exposure section V requires a recording time of at least 10 seconds, and the signal processing section (2) requires a meso buffer.

Therefore, in the present invention, as shown in the fJS9 diagram, only one pixel for each RGB color is sampled per horizontal scanning line of the television screen. That is, as shown in FIG. 8(a),
490 pixels of each BGH are sampled in the vertical direction per reproduction image forming time of one frame (consisting of an odd field and an even field), and this is taken as one recording scanning line for each color of RGB in the exposure system. That is,
The image from the left vertical part of the TV screen to the right side,
Exposure is recorded sequentially on photographic paper using FOT. In this way, it is only necessary to A/D convert one pixel for each color during the television horizontal scanning period of 63°5 μs, and the A/D converter ① is a low-speed one with a conversion speed of about 20 μ5. Just one piece is enough.

The relative sampling position of each color is, as shown in Fig. 6, the distance between the FOTI recording scan line r and the distance Q rg, and the distance between the recording scans llAg and b as Kagb. Sample points separated in time by TrSTg and Tb in FIG. 9 indicate the sampling time of each RGB signal.

From the above, the relative sampling time difference (T b
-Tg, Tg -Tr) and the RGB recording scanning line spacing Qgb, Qrg on the FOTI tube surface is as follows: (Tb-Tg)/△T=Qgb/D
...(5) (T g T r)/ΔT=Q rg/
D = 16) Here, ΔT is the sampling period of pixels of the same signal in the horizontal scanning line direction of the television screen, and D is the interval between adjacent recording scanning lines. 1/D is the recording density. If formulas (5) and (6) are satisfied, the image data of each color will overlap and no color shift will occur.

4 scanning −゛The pixel data obtained by sampling as described above is
For each color of RGB, there are 640 pixels in the horizontal direction and 490 pixels in the vertical direction of the TV screen, but if this was copied directly onto color photographic paper, the recording scanning line structure would be noticeable, and the pixels in the direction along the recording scanning line would be Since the intervals also become wider, it is necessary to interpolate them.

In the present invention, sampling is performed once and the result is 1! ), the pixel data of each RGB color is used twice in succession for exposure, resulting in 1280 pixels in the horizontal direction and 980 pixels in the vertical direction.
The number of pixels is doubled.

Therefore, in this case, the relationship between the above-mentioned relative sampling time difference and each scanning line interval on the screen of FOT 1 is (T b - T ir) / ΔT = gb / 2 D
...(5 Bi(T g - T r)/ΔT = Q rg
/ 2 D - (6)', and for example, if the recording scanning line interval is Q rg = Q gb = 3 mIa,
In the case of 1/D=8.6 pixels/11111,
The resolution between the recording scanning lines is 13 pixels. Formula (5)
If the relationships ' and (6)' are satisfied, color misregistration will not occur for the same reason as described above.

7 f7j' - This is a method of converting the gradation of an input signal by taking into consideration the characteristics of the human input signal, the light emission characteristics of the FOT 1, the sensitivity characteristics of the color photographic paper 6, etc., and is performed on the sampled RGB color data. In the present invention, a table lookup method is adopted in which characteristic data as shown in FIG. 10 is written in memory in advance and corrected output data is obtained by input data specifying the memory address. .

Figure 11 shows a circuit block diagram of the video signal processing section of the color image recording apparatus, including the portions described above. 10r, Log, 10bl! Terminal for inputting NTSC system TV image RGB signals, llr, 1
1. ．． 111) is an amplifier circuit with high-speed response characteristics that amplifies the RGB signals separately, 12r, 12g, and 12b are terminal 1
This is a sample-and-hold circuit that samples an input signal using a sampling pulse input from 3 and continues to hold that signal until the next sampling. Each of the sample and hold circuits is composed of an analog switch connected in series to a signal line and turned on and off by a sampling pulse, and a holding capacitor connected in parallel to the output side of the analog switch.

14A is an A/D converter which sequentially and separately converts the RGB sample signals from the previous stage circuit into 8-bit digital signals in response to a 2-bit RGB selection signal inputted to a terminal 15. This conversion is performed at terminal 16 (conversion start signal 5
This is done every time TART is input. A terminal 17 outputs a signal EOC indicating that the conversion has been completed.

181 and 182 output input data to the first and second line memories 19. and 192, these are the first and second data selectors that distribute the data.

The data selectors 181 and 182 transfer the input signal to the output side by receiving the signal rLJ at the output control terminal OC. The selector 182 receives the data as it is, and the other selector 18 receives the data in an inverted manner, thereby being selectively selected and transferring the input data to the output side. Note that when data is not transferred to the output side, the output side becomes a high-in-begin gate, and one-by-one flow of data from the line memory side is prevented. Line memo 1J19. and 192 enter the penetrating state by receiving the signal rLJ at the write terminal W, and enter the read state by receiving the terminal WC [Hl] and further receive the signal rLJ at the forward enable terminal OE. The terminal W of the first line memory 191 receives the selection signal DS of the terminal 22 and the write signal W of the terminal 23 via the NAND date 211, and the terminal W of the second line memory 192 receives the signal DS of the terminal Z2. Since the signal inverted by the inverter 20, the write signal W of the terminal 23, and the NAND date 212 are input, when one of the line memories is in the write state depending on the logical value of the selection signal DS, the other is not in the write state. No. Also, regarding reading, when one is in the reading state, the other is not in the reading state.

24 is a latch, and by inputting a selection signal DS to its terminal WS, the line memory 19. Alternatively, the transfer data from 19□ is latched. This latch is performed by, for example, 1.7 clocks of 100 kHz input to the terminal CK.

To summarize the above part, for example, the first data selector 1
81, the data is written to the first line memory 191, and at this time the second data selector 18. sets the output side to A impedance, and the second line memory 192 enters the read state and transfers the read data to the latch 24 at the next stage.

Here, sample hold circuits 12r, 12g, 1
The operation of the circuit from 2b to latch Z4 will be explained with reference to the timing charts of FIGS. 12 and 13.

As shown in the timing chart of FIG. 12, during the IH (initial horizontal scanning period) of an odd field, the R pixel data of the scan at the rising edge of the sampling pulse Sr is sampled, and then the sampling pulse S
Six pixel data at the scanning point at the rising edge of g and eight pixel data at the scanning point at the rising edge of the sampling pulse sb are sequentially sampled and held.

The RGB pixel data signals held in this manner are converted into digital signals at -1 by the A/D converter 14 in the order of R pixel data, G pixel data, and B pixel data. This A/D converter 14 inputs a 2-bit RGB selection signal to a terminal 15, and performs conversion processing every time a conversion start signal 5TART arrives at a terminal 16. In this conversion start signal, the start signal for R pixel data at the time of first conversion is obtained by processing the sampling pulse Sr, but the conversion start signal for the next 6 pixel data and 8 pixel data is the conversion end signal. It is obtained by processing the signal EOC.

The above sampling and A/D conversion are performed for pixels at the same time point from the horizontal synchronizing pulse l-1p for each RGB color from the first scanning line to the last scanning line of the odd field on the television screen, The same process is performed for subsequent even-numbered fields. That is, while forming one frame, the RGB in the vertical direction shown in FIG. 8(a)
R pixel data for 490 pixels are obtained along each line.

Next sampling and A″/D/D conversion (b
), while forming the next frame, the same applies to the pixel that is shifted by one pixel (corresponding to the above-mentioned Δt) along the horizontal scanning line of the television signal from the above pixel. and obtain the RGB pixel data there. Below, we sampled in the same way and added 1 per horizontal scanning line of the TV screen.
) Obtain 640 pixel data for each color of RG and B.

The digital data for each vertical RGB line shown in FIG. 8(a) obtained by conversion as described above passes through either the first data selector 183 or the second data selector 182, and First line/Mori 191. It is temporarily stored in either the second line/memory 192. - Here, when the selection signal DS is rHJ, the first data selector 18. is selected and the first line memory 19. is not in the read state, the NAND date 21 opens the date, the second line memory 192 is in the read state, and the NAND date 212 closes the date.

Therefore, in the first line memo January 91-1, terminal 2
Each time a write signal is applied to 3, pixel data of each color of RGB is written. This writing is performed over one frame, and in total, ν1 for each color of RGB is a pixel in the vertical direction of the television screen (see FIG. 8(a)), that is, 49 pixels each.
0 pixel data is written.

On the other hand, in the second line memory 1921, the pixel data previously written in the same manner as above is read out, but the reading is performed by reading out 490 pixels of R pixel data twice consecutively from the first pixel data. served, totaling 9
80 pixels are read out.

Next, 0 pixel data for 980 pixels is read out twice in the same way, and then 3 pixel data is read out for 980 pixels in the same way twice and transferred to the latch 24. As a result, the pixel data along one recording scanning line for each of RGB becomes 980 pixels.

The reading of this RGB pixel data is completed during sampling and A/D conversion for one frame,
Exactly the same readout is performed in the time corresponding to the next frame. Therefore, although the sampling rate was 640 per horizontal scanning line of the television screen, pixel data for 1280 recording scanning lines, which is twice that, can be obtained. As a result, adjacent recording scanning lines are exposed with the same pixel data, filling the spaces between the recording scanning lines and preventing the scanning lines from standing out.

Since the selection signal DS repeats once every two frames (see FIG. 13(g)), the data selector 18. and 18
□, line memo IJ19. and 192 are switched every two frames, and the line memories 19 and 192 are switched every two frames.
Pixel data is written alternately, and the written pixel data is read out alternately (Fig. 13(c), (
d)).

Reference numeral 25 denotes a γ correction circuit, which is composed of a ROM storing correction characteristic data as shown in FIG. 10, for example. For data reading, 8-bit pixel data from the latch 24 is input as an address signal, and pixel data corrected from the input data is sent out from the output. Note that the pixel data to be output is 10 bits so that more fine-grained gradation can be expressed. In this γ correction circuit 25, each characteristic for R, G, and B is selected by a 2-bit RGB selection signal applied to a terminal 26. Note that a mask signal for making the output pixel data zero luminance data is also applied to this terminal 26 at a specific timing, which will be described later.

27 is a buffer, 28 is a D/A converter that converts digital pixel data into an analog signal, 29 is an amplifier circuit, and 30 is a driver that converts the pixel data signal to a level that can drive FOT 1. 31 is a horizontal deflection circuit that outputs a horizontal sweep signal for FOT i, and the line memo 17
19. ．． In synchronization with the reading of pixel data from 192, a triangular wave shown in FIG. 13(e) is output. 32 is a vertical deflection circuit that outputs a vertical sweep signal, and outputs a signal (see FIG. 13(r)) that determines the horizontal sweep position for RGB.

This vertical deflection circuit 32 receives an R recording scanning line reference position signal V
r, G recording scanning line reference position signal Vg, and B recording scanning line reference position signal vb by analog switches 33r and 338.3.
3b selectively inputs and outputs. 34 is a terminal for inputting a 2-bit RGB selection signal for making the selection; 35
is a logic circuit that generates a selection timing signal. The analog switch is 33", 33FK.

33b, the reference position signal is switched to Vr.

V=, vb are output in this order in synchronization with the horizontal sweep.

Reference numeral 36 denotes a ROM"F memory that stores recording scanning line position movement amount data for eliminating vertical streaks due to uneven light intensity on the front surface of FOT 1. From this memory 36,
For each frame of the input video signal, each time each RGB scan by FOT 1 is completed, new data is read out, converted to an analog signal by the D/A converter 37, and corrected. It is applied as a signal to the vertical deflection circuit 32.

Therefore, each recording scanning line reference position signal Vr, v for RGB
By adding the above correction signal to g and vb, each RGB recording scanning line position becomes a position moved from the reference position (rgb in Fig. 6), and this position changes as explained in Fig. 7. , fjS7 The light quantity correction as explained in FIG.

When moving the recording scanning line in the opposite direction to the conveyance direction of the color photographic paper, the data of the movement amount S2 is
2.2S2.3S2...100S2...and then when moving in the same direction as the conveying force direction...100S2...3 S 2.2S2, S
.

so that it continues to decrease. Therefore, the memory 36 has more than one S, 2S2.3S2...100S2...
Store data like this and read it out in order. When exposing one sheet of color photographic paper, reading is performed 4 to 10 times back and forth.

When moving the recording scanning line in the same direction as the conveyance direction of the color photographic paper, as explained in FIG. input the pause control signal to 1.
Pixel data with zero luminance is output to the output side of the γ correction circuit 25 during the frame formation time, regardless of the input data.

Further, even during this pause, pixel data is read out in the line memories 191 and 192, but this pixel data is not used for recording. Therefore, the pixel data read out during the pause is read out again in succession so that the continuity of the image is not impaired.

Therefore, in this case, if the selection signal DS is inverted when 2 frames are completed, the next time it is inverted when 37 frames are completed, and the next time it is inverted when 2 frames are completed.

By the way, when changing the recording scanning line position as described above, a difference occurs in the average amount of light at each scanning line position, and this time, instead of the vertical stripes along the conveyance direction of the color photographic paper, the horizontal stripes along the scanning line direction Since streaks may be noticeable, correction is required to keep this average light amount constant.

Therefore, the correction signal from the D/A converter 37 in FIG.
After adjusting again according to each color of B, analog switch 3
9r, 39g, and 39b) In synchronization with the exit of the RGB signals from the D/A converter 328, the amplifier circuit 29 adds the RGB signals to perform brightness adjustment.

Level adjusters 38r, 38g, 38b are FOTI
Since the brightness in front of the color filters 5r, 5g, and 5b is not necessarily the same, this difference is adjusted in advance.

In addition, when exposing by FOTI, color photographic paper 6
At both ends along the transport direction, at least the distance between the R and B recording scanning lines of FOTl (r1rg+QgbH, see Figure 6), the same location cannot be exposed to the three primary colors of RGB, resulting in a discolored image. . Further, complete data may not be obtained at the time of sampling on both sides of each recording scanning line of each RGB. Therefore, in order to avoid exposing the four circumferential parts of the color photographic paper 6, when the pixel data of those parts is inputted to the γ correction circuit 25, a mask signal is inputted from the terminal 26, and the four circumferential parts are Mask the data so that the four circumferential parts are not exposed.

! -12 Hereinafter “margin” white ,□　,ノ This will be explained next.

This color image recording device' has a CPU 5 shown in FIG.
2 and others, the operation is controlled according to a preset program and exposure is performed.

The control clock in this case is, for example, 600 Hz. Next, the exposure control operation will be explained with reference to charts 70 after #IJ14.

First, start the start key (operate it each time you start exposure).

), the entire device is set to its initial state by the initial setting routine shown in FIG.

In step 131, the supply magsin 73 and the receiving magazine 1 are
It is determined whether the lid No. 20 is open or not. This lid opening detection is performed by a microswitch 79.113. If the answer is no (hereinafter referred to as N. If yes, it is referred to as Y), the opening of the lids is checked again in step 132, and it is determined again in step 133 that if both lids are still not open, then In step 134, a warning (buzzer sounding, display lamp lighting, etc.) is issued to indicate that the lid has not been opened.

If the lid is open, set P mode to 1 in step 135.
and the E mode is set to 2 in step 136. P mode=1 is the exposure start mode. E
The mode is a mode in the middle of exposure, and is expressed in 5-bit logic as follows.

E mode = 1 → 00001 2 → 00010 3 → 00011 〃　　4　→　ooio.

5 → 00101 〃 8 → 01000 16 → 10000 Then, in step 137, the supply motor 56 is turned on, the paper presence/absence sensor 59 is turned on, and then step 13
Step 8 resets all trouble counters (paper-free trouble counter and paper-dropping trouble counter) to zero. next,
In step 139, the supply motor 56 leaves the home position (when the suction cup 85 starts to move upward, α). After leaving the home position described above, the process proceeds to the exposure operation routine shown in FIG. 15.

In this routine, the current E mode is determined from step 141 to step 145 until the condition is met. As mentioned above, since the E mode is currently 2, the logic is [0OO10J, so the result in step 142 is Y, and the photographic paper removal routine FFB1 is entered. This routine is shown in FIG. 16, and step 151 At this time, it is determined whether or not there is a color print wk6 in the supplying machine 73 by the paper presence/absence sensor 59 which is turned on. If N, it is determined again in step 152 whether or not the supply motor 56 is in the home position, and if N, the process returns to the routine shown in FIG. Detection is 2
It is determined in step 153 whether or not the time has passed. If N, that is, if it is the first time, the paper presence/absence trouble counter is incremented by 11 in step 154, and the process returns to step 139 of the routine in FIG. 14 to detect it again. If the determination in step 153 is Y, in step 155 the paper feed motor 56
, turn off the paper presence/absence sensor 59, and step 15
At step 6, a paper out alarm is issued to notify that the color photographic paper in the supply machine 73 is out.

That is, here, the presence or absence of color photographic paper is detected by the paper presence/absence sensor 59, but if there is no detection result, it may be a false detection, so the same detection is performed again and an alarm is generated if there is no detection result. let

If the determination in step 151 is Y, in step 157 the conveyance motor 57 is turned on and the supply roller 96 is turned on.
The conveyance roller 104 is rotated, the supply sensor 60 is turned on, and the used paper presence/absence sensor 59 is turned off. Then, in the next step 158, the E mode is set to 4, and the 15th
Returning to the routine shown in the figure, judgments are made in order from step 141.

Since the logic of E mode=4 is l"0O100J, the judgment at step 143 is Y, and the process enters the photographic paper feeding routine FFF1 shown in FIG. is determined, and in the case of N, the process returns to the routine shown in FIG.
It is judged by the detection operation of. If the judgment in this step 162 is N, the next step 16 is
3, it is determined whether the judgment is the second time. If it is the first judgment, the result is N, the paper dropout trouble counter is set to 1 in step 164, the E mode is set to 2 in step 165, the conveyance motor 57 is turned off and the supply roller 96 is stopped in step 166, and further In step 167, the paper presence/absence sensor 59 is turned off again, and the paper feed sensor 60 is turned off. Then, the process returns to the routine shown in FIG. 15 and repeats the operation of taking out the paper. If the determination in step 163 is Y, both motors 56 and 57 are turned off and supply sensor 60 is turned off in step 168. Then, in the next step 169, a paper dropout alarm is issued.

That is, if the color photographic paper does not bite into the paper feed roller 96, the paper feed sensor 60 detects the color photographic paper up to two times in the same way as when taking out the color photographic paper described above, and the sensor 60 still detects the color photographic paper. If not, sucker 85
It is determined that the color photographic paper taken out from the supply machine 73 has fallen off during the process, and an alarm is issued.

When it is determined by the operation of the paper feed sensor 60 that the color photographic paper has bitten into the supply roller 96', the process proceeds to step 162.
becomes Y, and the process proceeds to step 170, where the paper feed motor 56 is turned off to stop taking out photographic paper, the paper feed sensor 60 is turned off, and the obsolete sensor 61 near the FOTI is turned on. Then, in step 171, the E mode is set to 1, and the process returns to the routine shown in FIG.

Since E mode = 1 is "00001" in logic,
Step 141 becomes Y, and the conveyance/transfer of photographic paper in FIG.
The exposure routine FFF2 is entered. First, since it is N in step 181, the process proceeds to the next step 182, and here also N.
Therefore, the process advances to the next step 183. Then, the photographic paper conveyed by the paper feed roller 96 bites into the lower conveyance roller 104 until it is detected by the paper discharge sensor 61.
The same steps of this routine FFF2 and the routine shown in FIG. 15 are performed sequentially.

When detected by the paper discharge sensor 61, step 183 becomes Y, so step 184 sets E mode=5, and step 185 sets the time counter to T3. This T3 is a distance L3 downward from the paper discharge sensor 61 (the first
(see figure) is the time required to further feed the photographic paper. This is because when the leading edge of the photographic paper bites into the transport roller 104, the end has not come off the paper feed roller 96.
This is to allow the paper to be fed further so that the end comes off the paper feed roller 96.

Returning to the routine in Figure 15 again, this time E mode = 5.
Since the logic is roololJ, step 141 becomes Y as above, and the photographic paper transport/exposure routine FFF
Enter 2 again. Since step 181 is N and step 182 is Y, the time counter set to T3 is decremented in step 186. Then, the same steps of this routine and the routine of FIG. 15 are repeated in sequence until the content of the counter is determined to be zero in step 186'.

When time T3 elapses and the time counter reaches zero, step/step 186' becomes Y, and step 187 turns off the paper ejection sensor 61, and also turns off the conveyance motor 57 to stop the rotation of the conveyance roller 104. . At this time, the leading end of the photographic paper has advanced by L3 from the paper discharge sensor 61, and the leading end has come off the paper feed roller 96.

Next, in step 188, the process waits for about 0.2 seconds, and then in step 189, the conveyance motor 57 is reversed, the conveyance roller 104 is reversed, and the photographic paper stuck there is reversed. Next, in step 190, set E mode to 8, and in the next step, set the time counter to Ti+T.
Set 3. In T1, the leading edge of the photographic paper is the transport roller 10.
This time corresponds to the distance Ll (see FIG. 1) required to back up to the limit without coming off the cut-in portion of No. 4.

Return and try again! Returning to the routine shown in FIG. 15, since the logic is [0100OJ in E mode=8, step 144 becomes Y, and the photographic paper reversal routine FFB2 shown in FIG. 19 is entered. Here, the time counter set in step 201 is decremented by 1, and the process proceeds to step 202, where the same steps of this routine and the routine of FIG. 15 are repeated in sequence until the time counter becomes zero. Then, when the time Ti+T3 has elapsed, step 202 returns Y.
Therefore, in step 203, the conveyance motor 57 is turned off to stop conveyance under CPU control. In the next step 204, an exposure start signal is sent from the CPU 52 to the video signal processing section 51 to start exposure. During this exposure, the photographic paper is transported by a transport motor 57 using a signal synchronized with the exposure scanning signal in the video signal processing section 51.
is performed by controlled rotation. And Ste, Bu20
In step 5, the E mode is set to 16, and when the exposure is confirmed in step 206, a message indicating that exposure is in progress is displayed in step 207, and the process returns to the routine shown in FIG.

In this routine of FIG. 15, since E mode = 16 this time, the logic is "10000" and step 14
5 becomes Y. Therefore, the photographic paper exposure end routine shown in FIG. 20 is entered. The steps between step 211 and the routine of FIG. 15 until the exposure is completed are performed sequentially. When the exposure is completed, the exposure display is turned off in step 212, and the discharge sensor 61 is turned on to enable detection. Next, in step 213, the conveyance motor 57 is turned on again for CPU control. Then, in step 214, the E mode is set to 3, and then the time counter is set to T2.

This time T2 is the time until the photographic paper leaves the conveyance roller 104.

When the program returns to the routine shown in FIG. 15 again, the E mode is 3, so the logic is "0OO11" and step 1417>-Y. Therefore, the photographic paper conveyance/exposure routine FFF2 shown in FIG. 18 is entered. and,
Since step 181 is Y, step 192 is T2.
After decrementing the time counter set to 1 by 1 and proceeding to the next step 193, the same steps as in the routine shown in FIG. 15 are executed sequentially. When time T2 elapses, the time counter becomes zero and step 193 becomes Y.
In step 194, the conveyance motor 57 is turned on and the conveyance rollers are stopped. 'And the next step 19
In step 5, it is determined whether or not the ejection of the photographic paper has been completed by the detection operation of the paper ejection sensor 61, and if Y, the completion of paper ejection is notified by a short buzzer or the like in step 196. If the paper ejection sensor 61 does not detect completion of paper ejection, that is, if it continues to detect photographic paper, the paper ejection sensor 61 is switched to step 197.
to turn it off, and in the next step 198 an alarm is issued for paper ejection trouble.

As described above, in this control, photographic paper is taken out -> paper fed -> conveyed -> exposed -> discharged, but at the time of taking out, the presence or absence of paper is detected, and if there is no paper, it is checked twice. Also, suction cup 85
We also check up to two times to see if the photographic paper has fallen out of the suction cup when we take it out and move it to paper feed. Therefore, troubles related to feeding of photographic paper can be effectively dealt with. Furthermore, when the leading edge of the photographic paper is biting into the conveying roller 104, the end is still biting into the paper feed roller 96, so conveyance is reliable, and exposure is performed with the edge removed from the paper feeding roller. Therefore, the occurrence of deviations in the exposure transport can be effectively prevented.

Another automatic processing apparatus used in the present invention will be described below based on embodiments shown in the drawings.

FIG. 21 is an external view of this device (with a printer section partially omitted), and FIG. 22 is an exploded perspective view thereof.

Figures 23 and 24 respectively show the A-A sectional view and the B-B sectional view in Figure 21.The upstream side of ε is a schematic diagram of the internal configuration as in Figure 1. , and regarding the reference numerals used in these drawings, the same structural parts as in FIG. 1 are designated by the same reference numerals.

As described above, a developing tank, a bleach-fixing tank 303, and a washing alternative processing liquid Wl (17-ounce tank) 304, 305, and 306 are provided in the automatic processing apparatus main body 301, and each tank has a processing liquid. A transport roller for transporting photographic paper and a transport rack consisting of a wA moving gear train are removably provided.

The photographic paper sent from the printer section Y is inserted through the entrance ε, is held by a group of rotating feed rollers, moves downward, and is conveyed to the developer tank 302.

In FIG. 23, the dashed-dotted line indicates the transport path of the photographic paper.

At the top of the developing tank 302, there are a photographic paper receiving roller 302A and a feeding/squeezing row 2302B, and inside the developing tank 302, a plurality of idle rollers 302C are rotationally driven. The photosensitive material is transferred to these rollers 302A.
, 302B, and 302C, and is immersed in the developer 'D contained in the tank, and after being developed during the movement for a certain period of time, is conveyed to the next bleach-fix tank 303.

The bleach-fixing tank 303 includes a roller 303A for receiving and sending out photographic paper, and an idle roller 303C, and the photographic paper subjected to the development process is fixed by the fixing solution F in this bleach-fixing tank 303 and is transported. .

The photographic paper that has undergone the development and fixing processes described above is subsequently led to a first rinse tank 304, a second rinse tank 305, and a third rinse tank 306. These washing and stabilizing tanks contain washing W or a stabilizing solution, and by immersing the photographic paper through each tank, the bleach-fixing solution F is washed away and a stabilized image is obtained. Photographic paper that has undergone stabilization is
It is squeezed and sent out by the final roller 306A.
It is conveyed along the drying plate and sent to the next drying chamber 307.

Inside the drying chamber 307, there is a group of conveying rollers that nip and convey the photographic paper that has been stabilized. After the stabilization process, the wet photographic paper is transported and passed through the drying chamber 307, where it is dried by a stream of warm air.

The photographic paper that has passed through the drying chamber 307 is transported to the exit 3.
09 to the outside, placed on the pedestal 313,
Terminate the process.

When a large amount of photographic paper is continuously processed using an automatic processing device such as the one described above, each processing solution stored in each processing tank will wear out and the processing capacity will decrease, so in order to compensate for this, It is necessary to replenish each processing liquid according to the processing amount of photographic paper, similar to the automatic development processing section described above, and to always maintain a constant processing capacity and processing liquid amount.

In this embodiment, a pump for replenishing the processing liquid and a tank for accommodating the processing liquid for replenishment are made into one unit, which is arranged on the processing tank. That is, above the developer tank 302, a developer container 321 and a developer tank 3 for replenishment are provided.
22 and a liquid quantitative replenishment device 323.

The developer container 321 has an over 70-tube 321A that limits the rise in the liquid level when the replenishing developer reservoir is filled therein.

Figure 25 is 11! l Light liquid tank, e.g. developer tank 3
22 is a sectional view showing an embodiment of the invention. Developer tank 32
2 is an airtight container having an opening 322A at its lower part, and the opening 322A is connected to a movable plug 324 and a spring 325.
It is sealed tightly by

When the developer tank 322 is connected to the developer container 321, the protrusion 32 on the bottom of the developer container 321
1B, the movable plug 324 moves upward against the pressure of the spring 324, and opens the opening 322A. Here, since the lower end of the opening 322A and the upper end of the overflow pipe 321A are arranged at approximately the same height, the developer liquid in the developer tank 322 flows out from the opening 322A, but the overflow tube 321A
- When the water level reaches the upper end surface of the pipe 321A, the outflow stops and an equilibrium state is reached.

On the other hand, in the upper right chamber of the developer container 321 (see FIG. 24), a liquid quantitative replenishment device 323 is provided, from which a quantitative object 326 is suspended. The liquid quantitative replenishment device 323 converts the rotational movement of a motor (not shown) or the like into vertical movement using the eccentric shaft 327! Ii structure allows the quantitative object 326 to move up and down between a position above the liquid level of the developer container 321 and a position where it is immersed in the developing QD.

Similarly, above the fixing tank 303, a fixing replenishment device 330 including a fixer liquid container 331, a fixer liquid tank 332, and a liquid quantitative replenishment device 333 is arranged. Additionally, above the rinse tanks 304, 305, and 306, there is a rinsing liquid replenishment device 340 that includes a container 341 that stores the washing liquid W or the stabilizing liquid S, a tank 342, and a liquid quantitative replenishment device 343.
is located. The structure, arrangement, and operation of each of these replenishing devices are substantially the same as those of the developer replenishing device described above, so a detailed explanation will be omitted.

Next, the operations of these replenishing devices will be explained.

In FIG. 24, the fixer liquid replenishing device 330 is shown in a state before liquid replenishment. At this time, the liquid level in the container 331 is at a height that closes the opening of the tank 332, that is, over 70 -
The liquid is filled to almost the same height as the pipe 331A. Further, the quantitative object 336 is kept suspended by the quantitative replenishment device 333 so as to be above this liquid level.

Next, it is necessary to count whether a predetermined number of photographic papers have been developed, measure the passage of a predetermined time, detect the concentration of a processing solution, or measure the black and white area of the photographic paper after development. As a result, one of the processing liquid replenishment signals is issued, and the corresponding liquid quantitative replenishment device is driven. As a result, the eccentric shaft 327, for example, is rotated to a lower position, and the quantitative object 326 is immersed in the developer liquid in the developer container 321. Since the liquid level in the developer container 321 is already almost aligned with the opening of the over 70-pipe 321A, the developer of approximately the same volume as the metering object 326 is in the over 70
- It overflows from the tube 321A and is directly replenished into the developer tank 302 below.

Even when a certain amount of developer is replenished into the developer tank 302,
When the metering object 326 is pulled up, the developer in the container 321 decreases by the volume of the metering object 326, and the liquid level drops, but the developer immediately flows out from the tank 322 through the opening 322A and The liquid level will recover to a height that closes the opening 322A.

The volume of the quantitative object is ′g of each processing solution replenished at one time.
Since it is a product of 326 degrees and 336 degrees of quantitative objects for each treatment tank.
346 volumes may be determined as required volumes.

In addition, tanks 322, 332, 34 containing each replenisher
If part or the entire wall of 2 is made of transparent or semi-transparent material, 1 part of the processing liquid remaining in each tank can be
Since it can be visually observed, replenishment of the processing liquid is ensured.

When the replenisher in each tank is consumed and the remaining amount reaches a predetermined amount or less, dispose of the tank! ! ! Remove it from the liquid container and replace it. For example, when the developer tank 322 is pulled upward, the movable plug 324 separates from the projection 321A and seals the opening 321A from the inside by the pressure of the spring 25. Thereby, the tank 322 can be taken out without the developer remaining in the tank 322 leaking to the outside. Thereafter, when a new replenisher tank filled with developer is loaded into the fitting portion of the developer container 321 in the same manner as described above, the developer is replenished again. Replacing the fixer tank 332 and stabilizer tank 342 is also easy.
This can be done reliably.

In addition, a container 321 and a tank 32 of the developer supply device 320
2. The quantitative replenishment vc unit 323 is configured as one unit, and the fixing replenishment device 330 and the rinse liquid replenishment device 3 are also configured as one unit.
40 are each configured as a unit, and each unit can be easily attached and detached from the main body 301 of the apparatus, so maintenance, inspection, repair, etc. can be performed extremely easily and reliably.

Furthermore, replenishment liquid tanks 322, 332, 342 for each processing liquid
Since the quantitative replenishment devices 333 and 343 are arranged between them, it is possible to prevent the replenisher from mixing into the adjacent processing tank.

FIG. 26(a) is a sectional view showing another embodiment of the processing liquid replenishing device according to the present invention, and FIG. 26(b) is a partial sectional view thereof.

Processing liquid, container 351 has warm liquid port (over 70-pipe) 3
In addition to 54, a protrusion 356 for draining the liquid from the replenisher tank 352 and an id 357 for guiding the metering object 353 are provided.

In order to prevent the processing liquid from overflowing from the opening 355 when the replenisher tank 352 is removed from the processing liquid container 351, the opening 36 has a sealing plug 359 and a packing 360 that seal the opening 355 by the biasing force of a spring 358.
1, and the replenisher tank 352 is connected to the positioning pin 3.
62 and attached to the processing liquid container 351, the protrusion 356 pushes up the sealing plug 359 against the biasing force of the spring 358, and the sealing plug 359 and the seal 36
0, thereby opening the opening 355.

The quantitative object 353 is attached to the hanging wire 36 via a hook 363.
4, and as shown in FIG. 26(b), the hanging wire 364 is screwed into a screw thread 367 provided on a bracket 368 fixed to the rotating shaft 365a of the motor 365. It is hooked via a pin 366a to a winding shaft 366 which can move up and down by 1531 g by rotating the pongee 367.

Then, even though the motor 365 rotates in one direction, the quantitative object 35 remains in the state shown in FIG. 26(a).
3 is raised, and when the motor 365 further rotates, the metering object 353 is then lowered.

In this case, a screw shaft 367 is provided on the bracket 368 fixed to the rotating shaft 365a of the motor 365, and since the winding shaft 366 is screwed onto this screw pongee 367, the screw shaft 368
Since the winding shaft moves up and down by rotating 67,
The initial vertical position of the quantitative object 353 can be set, and the winding shaft 36 when the motor 365 rotates can be set.
6 can be changed, and thereby the amount of immersion of the quantitative object 353 can be changed.

The bracket 368 also includes an actuator bin 3.
69 is provided, and this actuator bin 369 acts on the actuator 371 of the microswitch 370, so that the timing of rotation and stop of the motor 365 is controlled.

Next, the operation of the above-mentioned device will be explained.

First, in a steady state, the quantitative object 353
As shown in Figure (a), it is immersed in the processing liquid.

-This is the place that handles it! When J and wL are left in the air, they solidify and adhere to the surface of the quantitative object 353, which causes the apparent volume of the quantitative object 353 to fluctuate, impairing the accuracy of determining the amount of liquid to be replenished. This method takes into account that there may be cases in which this happens, and is a suitable method in such cases.

Then, from the state shown in tJS26 figure (a), the motor 36
5 is rotated in a direction to raise the quantitative object 353, the quantitative object 353 is pulled up and the liquid level in the processing liquid container 351 is lowered from the height shown in the figure.

As a result, air bubbles enter the replenisher tank 352 through the opening 355 , and the replenisher flows out from the tank 352 .
Restore the liquid level to a height that covers 5.

Furthermore, when the motor 365 rotates, the quantitative object 353 is immersed in the processing liquid, and a fixed amount of the processing liquid based on the volume is transferred from the processing liquid container 351 to the hot liquid port (hot liquid pipe) 354. It will be replenished into the processing tank through.

Then, the lifting height is adjusted to prevent the quantitative object 353 from being completely pulled up from the processing liquid.
The amount of liquid to be replenished can be changed by adjusting step 7.
In addition, if the processing liquid container 51 is made small and deep, it is possible to replenish a very small amount of liquid with high accuracy.

On the other hand, if the processing liquid container 351 is made large, it is possible to replenish a large amount of liquid at a constant rate.

When the automatic development processing section described in FIGS. 21 to 24 is used in this image recording apparatus, a known sheet reversing mechanism is used in the conveyance path RO, and when the photographic paper is inserted into the entrance ε, the emulsion If the surface (image recording side) is on the top, the drying rack 307
Since warm air is blown onto the emulsion side of the photographic paper, drying is quick, and the recorded image can be checked as it is when placed on the pedestal 313, which is desirable.

The exposure device used in this image recording device is FOT.
In addition, solid-state light control elements such as liquid crystal shutters (patent application 1983)
-226413) Alternatively, a laser optical system using a semiconductor laser, a slave, etc. can be applied.

(Effects of the Invention) As described above, according to the present invention, a color hard print can be obtained in a bright room based on a video signal by a series of operations just by setting the photosensitive material, so the operation is easy.
Moreover, an extremely good image can be obtained and a compact image recording device can be provided.
