Further, the medium transport block 101 on the reproducing unit 31 side is the same as the medium transport block 4 of the image pickup unit 1 described above except for the feed amount of one pitch, and is structurally the same. It is shared with one side. That is, as shown in FIG. 8, a pair of pinch rollers 15 and 1 is provided on each of the supply roll 6 side and the storage roll 7 side.
6 are arranged, and each pair of pinch rollers 15 and 16
The recorded recording medium 38 is sandwiched between them. A first path length adjusting mechanism 17 and a second path length adjusting mechanism 18 are provided between the pinch rollers 15 and 16 and the irradiation surface of the light source 36.

Each of the path length adjusting mechanisms 17 and 18 includes a pair of fixed rollers 17a, 17b, 18a and 18b which come into contact with the base 11 side of the photosensitive recording medium 8 (see FIG. 3A), and the fixed rollers 17a and On the extension line between 17b, 18a, and 18b, movable rollers 17c and 18c movable in a direction orthogonal to the recorded recording medium 38 are provided. The movable rollers 17c and 18c are V of the recorded recording medium 38.
The entire area is is in pressure contact with the photosensitive layer 13 side. The movable rollers 17c and 18c are reciprocally driven in the above direction by an actuator (not shown), and the pinch roller 16 and the storage roll 7 are rotationally driven at the same linear velocity via a motor (not shown) and a speed reduction mechanism. Then, the operations of these actuators and motors are controlled by the main controller 2, whereby the adjacent fixed rollers 17b, 18
The respective optical images 19R, 19G, 19B recorded on the recorded recording medium 38 extending between a are intermittently driven as described later.

In the present embodiment having the above-described structure, the pinch roller 1 is operated when the image pickup is not performed because the motor is in the non-operating state according to the instruction from the main controller 2.
5, 16 and the storage roll 7 have stopped rotating, and thus the photosensitive recording medium 8 has also stopped. At this time, as shown in FIG. 10A, 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. Then, the pinch rollers 15 and 1
6 and the storage roll 7 start rotating, the actuator operates and, as shown in FIG. 7B, in the movable roller 17c of the first path length adjusting mechanism 17, the photosensitive recording medium 8
The movable roller 18c of the second path length adjusting mechanism 18 simultaneously moves from the neutral position N in the backward direction away from the neutral position N by the equal distance L1.

Therefore, during that time, the photosensitive recording medium 8 pulled out from the supply roll 6 with the rotation of one of the pinch rollers 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 the operation at 1/30 second intervals, the photosensitive recording medium 8
Is pulled out from the supply roll 6 at a constant speed, and the storage roll 7
While being wound up at the same speed,
At intervals of / 30 seconds, the stationary rollers 17b and 18a stand still. Therefore, as shown in FIG. 11A, 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. By moving the intermittent moving unit 8a at the closing timing, the R optical image 19R, the G optical image 19G, and the B optical image 19R for each of the R, G, and B components are still images every 1/30 second of the captured image. Optical image 1
9B can be sequentially exposed to each frame 19 ...

On the other hand, in the developing and fixing unit 20, the lid of the tank 21 is driven to open in response 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 and fixing solution permeates the Vis whole-area photosensitive layer 13 of the photosensitive recording medium 8, and the Vis whole-area photosensitive layer 13 develops an absorption spectrum having a peak at the wavelength λ1. At this time, as shown in FIG. 12, the developing / fixing unit 2 is moved to the photosensitive recording medium 8 at a constant speed moving portion moving at a constant speed (v).
When 0, the developing and fixing solution is applied. Of course, when the imaging is stopped, the lid of the tank 21 is closed,
Excessive developing and fixing solution is not applied to the stopped photosensitive recording medium 8. Therefore, in the photosensitive recording medium 8,
The developing and fixing solution is applied in a uniform amount over the entire length, whereby the developing and fixing effect of each frame 19 can be made uniform.

Further, as described above, the picked-up image formed on the photosensitive recording medium 8 by the surface image-forming optical system 9 and projected through the color separation optical system 11 is converted into an electric signal. Since it is recorded directly without intervening,
Optical images 19R, 19G, 19B recorded on each frame 19
It is possible to secure the fidelity of the still image composed of the above with respect to the captured image. Moreover, since each frame 19 of the photosensitive recording medium 8 on which the still image is exposed is sequentially developed and fixed by the developing and fixing unit 20, a reproducible recording medium can be obtained at the same time as the image pickup is completed.

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.
Both movable rollers 17c and 18c of 8 are set 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)). Next, when the reproduction is started, the motor is started in accordance with the instruction from the main controller 2, so that the pinch rollers 15 and 16 and the storage roll 7 start rotating at the same constant linear velocity. Then, at the same time as the rotation of the pinch rollers 15 and 16 and the storage roll 7 starts, the actuator operates according to the instruction from the main controller 2, and as shown in FIG.
The movable roller 17c of the
The movable roller 18c of the second path length adjusting mechanism 18 simultaneously moves from the neutral position N by the equal distance L3 in the backward direction in which the movable roller 18c of the second path length adjusting mechanism 18 approaches.

Therefore, during that time, the recorded recording medium 38 pulled out from the supply roll 6 in accordance with the rotation of one of the pinch rollers 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 recorded recording medium 38 is shortened on the side of the second path length adjusting mechanism 18, and the surplus generated by this is caused by the rotation of the pinch roller 16 and the storage roll 7. Accompanying this, the storage roll 7
To be wound up. Therefore, during this period, the recorded recording medium 3 is recorded.
The intermittent movement unit 38a of 8 does not move and is stopped.

Then, in this way, the pinch rollers 15, 1
6 and the storage roll 7 continue to rotate at the same linear velocity, when 1/90 seconds elapse, the actuator operates in the opposite direction to the above, and as shown in FIG. In the movable roller 17c of the first path length adjusting mechanism 17, the movable roller 18c of the second path length adjusting mechanism 18 moves in the forward direction approaching the recorded recording medium 38.
The recording medium 38 and the recording medium 38 are simultaneously moved in the backward direction away from the recorded recording medium 38 by an equal distance L4.

Therefore, on the first path length adjusting mechanism 17 side, the path length of the recorded recording medium 38 is shortened, and at the same time, on the second path length adjusting mechanism 18 side, the path length of the recorded recording medium 38 is long. Turn into. Therefore, 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 same time, the fixed rollers 17b and 18 are fixed.
The intermittent moving portion 38a interposed between a is absorbed by the second path length adjusting mechanism 18 side.

Here, L3 and L4 shown in FIG.
The relationship between L1 and L2 shown in FIG. 10 is L3 = 1 / 3L
1, L4 = 1 / 3L2, and (B) in FIG.
While the operation of (C) has an interval of 1/30 second, the operation of (B) and (C) has an interval of 1/90 second in FIG. As a result, the recorded recording medium 38 is supplied to the supply roll 6
The optical images 19R, 19G, and 19B are drawn out at a constant speed from the
It stands still in front of the light source 36 at 0 second intervals. Therefore,
According to the instruction from the main controller 2, the optical image 19R,
The light source 36 is turned on when 19G and 19B are stationary, and the optical images 19R and 19R are turned on when the light source 36 is turned off.
By moving 19G and 19B, FIG. 14 (A)
As shown in FIG. 1, the R optical image 19R is first projected on the monochrome area sensor 39, and at intervals of 1/90 seconds, as shown in FIGS. Is imaged on the monochrome area sensor 39.

On the other hand, the sensor driver 40 is instructed by the main controller 2 to drive the monochrome area sensor 39 at the timing of FIG. 41 to transfer and output. The transfer output signal is subjected to the removal of the reset pulse and the adjustment of the signal level by the preprocessing circuit 41, then converted into digital image data by the A / D converter 47, and stored in the memory 49.
Therefore, first, the digital image data of the R component is stored in the memory 49.
Memorized in. Further, the monochrome area sensor 39 is driven at the timing shown in FIG. 7B, and when the G component digital image data is stored in the memory 49, the monochrome area sensor 39 is continuously driven at the timing shown in FIG. By driving, the B component digital image data is stored in the memory 49.

In this way, R for one frame,
When the G and B digital image data are stored in the memory 49, the operation matrix 50 uses the R, G, and B digital image data output from the memory 49 to calculate the luminance data Y, the color difference data RY, and While calculating BY, gamma correction and the like are performed at this time.
