In the present embodiment having the above-mentioned structure, when the image pickup is started, the photosensitive recording medium 8 in the non-image pickup state is set.
Are set as shown in FIG. At this time,
As shown in the figure, both movable rollers 17c and 18c are stopped at the same neutral position N retracted from the fixed rollers 17a, 17b, 18a and 18b by a predetermined distance.

Then, when the image pickup is started, the motor is started in accordance with the instruction from the main controller 2,
The pinch rollers 15 and 16 and the storage roll 7 start rotating at the same linear velocity, whereby the photosensitive recording medium 8 is fed in the transport direction F (see FIG. 2). Then, simultaneously with the start of rotation of the pinch rollers 15 and 16 and the storage roll 7, the actuator operates, and as shown in FIG. 9B, the movable roller 17c of the first path length adjusting mechanism 17 has a photosensitive recording. For the movable roller 18c of the second path length adjusting mechanism 18, in the backward direction away from the medium 8, in the forward direction toward the photosensitive recording medium 8, the equidistant distance L1 from the neutral position N, respectively.
Move at the same time.

Therefore, during that time, the photosensitive recording medium 8 pulled out from the supply roll 6 in accordance with the rotation of the one pinch roller 15 has its path length lengthened by the backward movement of the movable roller 17b, and the pulled-out amount is absorbed. To be done. Further, when the movable roller 18c moves forward, the path length of the photosensitive recording medium 8 is shortened on the side of the second path length adjustment mechanism 18, and the surplus generated by this is accompanied by the rotation of the pinch roller 16 and the storage roll 7. And is wound up on the storage roll 7. Therefore, during this period, the intermittent movement portion 8a of the photosensitive recording medium 8 is stopped without moving.

Then, in this way, the pinch rollers 15, 1
6 and the storage roll 7 continue to rotate at the same linear velocity, when 1/30 second elapses, the actuator operates in the opposite direction to the above, and as shown in FIG. The movable roller 17c of the first path length adjusting mechanism 17 moves forward in the direction approaching the photosensitive recording medium 8, and the movable roller 18c of the second path length adjusting mechanism 18 moves backward from the photosensitive recording medium 8. In the same direction, the same distance L2 is simultaneously moved.

Therefore, the path length of the photosensitive recording medium 8 is shortened on the side of the first path length adjusting mechanism 17, and at the same time, the path length of the photosensitive recording medium 8 is increased on the side of the second path length adjusting mechanism 18. . For this reason, the surplus on the side of the first path length adjusting mechanism 17 caused by the shortening of the path length arrives at both of the adjacent fixed rollers 17b and 18a, and at the time of the same figure (B), between the fixed rollers 17b and 18a. The intermittent moving portion 8a interposed in the second path length adjusting mechanism 18
Absorbed by the side.

The above operation shown in FIGS.
By repeating every 30 seconds, the photosensitive recording medium 8 is pulled out from the supply roll 6 at a constant speed and wound around the storage roll 7 at the same speed, while the intermittent moving portion 8a is sequentially moved to 1 /
At 30-second intervals, the stationary rollers 17b and 18a stand still. Therefore, as shown in FIG. 10A, the optical shutter 10 opens according to the instruction from the main controller 2 at the timing when the intermittent moving unit 8a is stopped, and the optical shutter 10 opens.
As shown in FIG. 6, by moving the intermittent moving unit 8a at the timing when the optical shutter 10 is closed, it is possible to sequentially expose the frames 19 ...

On the other hand, in the developing and fixing unit 20, the lid of the tank 21 is driven to open according to an instruction from the main controller 2 issued at the same time as the start of image pickup. As a result, the coating member impregnated with the developing and fixing solution is exposed to the outside of the tank 21 and comes into contact with the photosensitive recording medium 8 on which the still image of the subject image is exposed in each frame 19. Therefore, the developing / fixing solution permeates the R, G, and B photosensitive layers 12 to 14 of the photosensitive recording medium 8, and the photosensitive layers 12 to 14 cause R and G of the subject image to
According to G and B, the storage roll 7 is developed while exhibiting an absorption spectrum having different wavelengths λ1, λ2 and λ3 as peaks.
Is taken up by. At this time, the photosensitive recording medium 8 is
As shown in FIG. 11, the developing / fixing unit 20 applies the developing / fixing solution at the constant velocity moving portion moving at a constant velocity (v). Of course, when the imaging is stopped, the lid of the tank 21 is closed, so that the excessive development and fixing solution is not applied to the stopped photosensitive recording medium 8. Therefore, the developing / fixing liquid is applied to the photosensitive recording medium 8 in a uniform amount over the entire length thereof, whereby the developing / fixing effect of each frame 19 can be made uniform.

When the reproduction of the imaged result is started, the recorded recording medium 38 is rewound to the supply roll 6 side. This rewinding is performed by both path length adjustment records 17, 1.
8 both movable rollers 17c, 18c to the neutral position N (see FIG.
The operation is performed by rotating the supply roll 6 in the reverse direction while stopped at (A)). After rewinding, both rolls 6,
7, the recorded recording medium 38 and the reproducing unit 31
Side transfer block 101, and as a result, as shown in FIG.
As shown in, the recorded recording medium 38 is pressed between the pinch rollers 102, 102. When reproduction is started in this state, according to the instruction from the main controller 2, both the drivers 106, 1 are driven together with the pinch rollers 102, 102.
07 starts. Then, the laser light sources 36R, 36
While G and 36B operate, the motor 105 operates and the mirror 103 rotates. When the irradiation position P of each laser beam crosses once in the direction perpendicular to the transport direction A as the mirror 103 rotates, each laser beam transmitted through the top 19 reflects the recorded image density on one line. Receive intensity modulation. Each intensity-modulated laser light is incident on the corresponding light receiving sensor 39R, 39G, 39B and photoelectrically converted, and as a result, an electric signal correlated with a recorded image on one line on the frame 19 is generated. That is, every time the irradiation position P of each laser beam crosses the frame 19, the image signal of the 1-line component in the R component of the still image recorded in the frame 19 from the R light receiving sensor 39R is G An image signal of one line component in the G component is obtained from the B light receiving sensor 39G, and an image signal of one line component in the B component is obtained from the B light receiving sensor 39B.

These R, G, B image signals for one line are adjusted in signal level in preprocessing circuits 41R, 41G, 41B, and then the corresponding A / D converters 47R, 47G, 47B. Digitized by
The data is sequentially stored at designated addresses in the memories 49R, 49G, 49B managed by the corresponding memory controllers 48R, 48G, 48B. At this time, since the respective light receiving sensors 39R, 39G, 39B have the intervals of several lines as described above, the lines of the images to be read are shifted by several lines. Therefore, the memory controllers 48R, 48G, and 48B specify an address in consideration of the deviation of the read line, and the R, G, and B image data for one line is stored at the specified address. Therefore, by sequentially performing the above operation at the timing when each laser beam crosses the frame,
The R, G, B components that make up a still image of one frame are converted into data.

Then, the memory controllers 48R, 48
G and 48B are corresponding memories 49R, 49G and 49B.
The image data forming one screen for each R, G, B component is read out, and the operation matrix 50 is
Luminance data Y and color difference data RY and BY are calculated from the R, G, and B digital data output from R, 49G, and 49B while performing the above-described correction and the like. Also, D
The / A converter 51 converts the luminance data Y, the color difference data RY and BY from the operation matrix 50 into analog data. Further, the color encoder 45 generates and outputs a video signal for one screen based on the analog luminance signal Y and the color difference signals RY and BY. Therefore, by operating the passive TV set based on the video signals that are sequentially output, it is possible to visually recognize a color moving image that is a series of still images recorded in each frame 19, and a still image can be displayed by the video printer. You can also print it out.

Therefore, by using this image pickup / reproduction device 61, as shown in FIG.
All of "2. Automatic development" → "3. Reproduction" can be performed. As a result, the moving image f of the captured image F can be reproduced on the television receiver 65, the still image f ′ of the captured image F can be printed by the video printer 66, etc., quickly and smoothly.

As described above, the image reproducing apparatus according to the present invention irradiates a laser beam to read a still image recorded on a photosensitive recording medium for each color component and for each line component to obtain an image. A signal is generated. Therefore, the image can be reproduced at low cost without using the magnetic-image conversion means, and further, without being restricted by environmental conditions such as a dark place. Further, since the recorded image is read directly from the photosensitive recording medium, a higher reading resolution can be obtained and the reproduction image quality can be expected to be improved, as compared with a reproducing apparatus involving magnetic-image conversion.

That is, since the spot size at the irradiation position can be easily miniaturized by using the laser beam, high-density and high-resolution reading can be performed. For example, by the main scanning 4500 × the sub-scanning 8000,
Even resolutions up to 36 million pixels can be realized. Further, since the laser beam can easily generate a high-energy light beam, the intensity of the signal generated by the light receiving means becomes large. As a result, the time required to read one line can be shortened, which enables high-speed reading.

Further, by constructing the optical path control means by the rotatable mirror and the driving means for rotationally driving the mirror, the structure can be simplified and the cost can be reduced.

Further, in the image pickup / reproduction device of the present invention, since the image reproduction / reproduction device has both the function as the image reproduction device and the function as the image pickup device, the common function portion is shared to simplify the structure and further. It is possible to secure the advantages of the image reproducing apparatus described above while enabling the size reduction and the weight reduction.
