Is driven by the main controller 2
Controlled by.

In the present embodiment having the above-described 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, both movable rollers 17c and 18c are stopped at the same neutral position N, which is respectively retracted from the fixed rollers 17a, 17b, 18a and 18b by a predetermined distance, as shown in FIG. Then, when image pickup is started, the motor is started in accordance with an instruction from the main controller 2, so that the pinch rollers 15 and 16 and the storage roll 7 start rotating at the same linear velocity. Then, at the same time when the pinch rollers 15 and 16 and the storage roll 7 start to rotate, the actuator operates, and as shown in FIG.
The movable roller 17c of the second path length adjusting mechanism 18 is neutral in the backward direction away from the photosensitive recording medium 8 and the movable roller 18c of the second path length adjusting mechanism 18 is the neutral direction in the forward direction of approaching the photosensitive recording medium 8. Simultaneously move from the 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 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 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.

Then, 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 and 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)). Next, after rewinding, as shown in FIG. 8, the recorded recording medium 38 is set, and at this time, the starting end of the R optical image 19R of the first frame is set so as to be projected on the monochrome line sensor 39. To do.

When the reproduction is started, the main controller 2 keeps the pinch rollers 102 and 102 stopped,
First, the light source 36 is turned on. As a result, one line at the starting end of the R optical image is projected by the monochrome line sensor 39 via the imaging optical system 37.

Then, the sensor driver 40 is driven by the main controller 2 to drive the monochrome line sensor 39 at the timing when the light source 36 is turned on, and the pre-processing circuit 41 drives the accumulated charge by photoelectric conversion of the monochrome line sensor 39. Output to. 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, and then converted into digital image data by the A / D converter 47 and stored in the memory 49. First, digital image data of one line component of the R optical image 19R is stored in the memory 49.

When the digital image data of one line component of the R optical image 19R is stored in the memory 49, the main controller 2 operates the pinch rollers 102, 102 to move the recorded recording medium 38 to the minute size. After being moved in the conveyance direction A (the same direction as the conveyance direction at the time of imaging) with a pitch, the movement is stopped. As a result, the R optical image moves by one pitch and stands still, and each light source 36 is turned on within the time when the R optical image stands still. Thereby, based on the accumulated charge of the monochrome line sensor 39 at the lighting timing,
The image data of the next one-line component of the optical image 19R is stored in the memory 49.

Therefore, the above operation is performed by the R optical image 19R.
The digital image data of the R optical image 19R is stored in the memory 49 by performing the operation from the start end to the end. Similarly, when the recorded storage medium 38 is conveyed in the conveying direction A in small pitches, next, the G optical image 19G is generated.
Digital image data of B optical image 19B is successively stored in the memory 49. Then, the operation matrix 50 calculates the luminance data Y and the color difference data RY and BY from the R, G, B digital image data output from the memory 49, and at the same time performs gamma correction and the like. To do. Further, the luminance data Y, the color difference data RY and BY from the operation matrix 50 are analogized by the D / A converter 51, and the color encoder 46 is the analogized luminance signal Y and color difference signal RY. And BY generate and output a video signal.

In addition, the recording medium 38 is conveyed in the conveying direction A.
When the start end of the R optical image 19R of the next frame 19 is projected on the monochrome line sensor 39 in accordance with the movement to, the digital image data for each line component is sequentially stored in the memory 49 in the same manner as described above.
