Each recording area of the 9G and B optical image 19B constitutes one frame.

In this embodiment, each optical image 1
9R, 19G, 19B are separated in the horizontal direction along the moving direction of the photosensitive recording medium 8, and each optical image 1
The areas where 9R, 19G, and 19B are projected are shown in FIG.
As shown in, the horizontal (a) × longitudinal (b) = 9 × 16 mm, and the pitch p of disposing the tops 19 is 30 mm. Also,
In this embodiment, NTSC standard 30 frames /
According to sec, the imaging rate = 30 frames / sec and the effective length of 270 m in this embodiment, the imaging time is 5 minutes. Further, the optical shutter 10 is opened at a frequency of 30 times / sec according to an instruction from the main controller 2, and the opening operation time at that time is 1/50 to
It is about 1/1000 second.

In the medium carrying block 4, as shown in FIG. 7, the supply roll 6 and the storage roll 7 are spaced apart from each other.
And are rotatably arranged. A pair of pinch rollers 15 and 16 are arranged near the rolls 6 and 7, respectively, and the photosensitive recording medium 8 is pinched between the pair of pinch rollers 15 and 16. Also, both pinch rollers 1
In the vicinity of the inside of 5, 16
A second path length adjusting mechanism 18 is provided respectively. The color separation optical system 11 projects the optical images 19R, 19G, and 19B on the intermittent moving portion 8a of the photosensitive recording medium 8 extending between the path length adjusting mechanisms 17 and 18. There is.

Each path length adjusting mechanism 17, 18 includes a pair of fixed rollers 17a, 17b, 18a, 18b which come into contact with the base 11 side of the photosensitive recording medium 8 (see FIG. 3A), and the fixed rollers 17a, On the extension line between 17b, 18a, and 18b, movable rollers 17c and 18c that are movable in a direction orthogonal to the photosensitive recording medium 8 are provided.
Reference numerals 7c and 18c denote the entire Vis photosensitive layer 1 of the photosensitive recording medium 8.
It is pressed against the 3rd side. These movable rollers 17c, 18c
Is reciprocally driven in the above direction by an actuator (not shown), and the pinch rollers 15 and 16 and the storage roll 7 are driven.
Is rotationally driven at the same linear velocity through a motor and a speed reduction mechanism (not shown). The operations of these actuators and motors are controlled by the main controller 2, so that the intermittent moving portion 8a of the photosensitive recording medium 8 extending between the adjacent fixed rollers 17b and 18a is intermittently driven as described later. To be done.

On the other hand, FIG.
The developing / fixing unit 20 shown in FIG. The developing / fixing unit 20 is provided with a tank 21 having a vertical length that is substantially the entire width of the photosensitive recording medium 8. The opening and the opening are provided on the surface of the tank 21 facing the photosensitive recording medium 8. A lid (both not shown) is provided which is opened during imaging and closed during non-imaging. Further, in the tank 21, a developing / fixing solution used for a part of so-called instant photography and a coating member made of a sponge impregnated with the developing / fixing solution are stored. The coating member is configured to come into contact with the surface of the photosensitive recording medium 8 when the lid is opened, and the lid is operated by an actuator (not shown) that operates according to an instruction from the main controller 2. It is driven to open and close. The developing / fixing unit 20 is arranged near the storage roll 7 and at a position where the photosensitive recording medium 8 moves at a constant speed, for example, between the pinch roller 16 and the storage roll 7 shown in FIG.

In the present embodiment having the above-described structure, the pinch roller 1 is operated when the non-imaging operation is 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. 8A, 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.

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 operation shown in FIGS. 8 (B) and 8 (C) is 1
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. 9 (A), the optical shutter 10 opens according to an instruction from the main controller 2 at the timing when the intermittent moving unit 8a is stationary, and as shown in FIG. 9 (B), the optical shutter 10 opens. By moving the intermittent moving unit 8a at the closing timing, the captured image 1
It is possible to expose the R optical image 19R, the G optical image 19G, and the B optical image 19B for each R, G, and B component on each frame 19 ...

On the other hand, in the developing and fixing unit 20, the lid of the tank 21 is driven to open by 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. 10, 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. Become.

FIG. 11 shows another configuration of the color separation optical system 11. That is, the first dichroic mirror surface 26 that transmits B light and reflects R light and G light in a direction orthogonal to the optical axis on the optical axis of the surface imaging optical system 9 that is incident through the shutter 10. Is provided. A first total reflection mirror surface 27 that reflects all incident light in a direction parallel to the optical axis is provided on the side of the first dichroic mirror surface 26, and in front of the first total reflection mirror surface 27.

A second total reflection mirror surface 29 is provided in front of the first dichroic mirror surface 26 and on the side of the second dichroic mirror surface 28, and the other side portion of the second total reflection mirror surface 29 is provided. Is provided with a third total reflection mirror surface 30 that reflects all incident light in a direction parallel to the optical axis. Therefore, according to such a configuration, the surface imaging optical system 9 is configured by using only the mirror without using the prism.
It is possible to decompose the captured image from R into G, B, and B light components, and simplify the structure of the color separation optical system 11.

However, in the image pickup device 25 shown in the second embodiment, the color separation optical system 11 is arranged in the vertical direction orthogonal to the conveying direction of the photosensitive recording medium 8, and therefore, the respective optical images 19R, 19G, 19B is projected in the vertical direction.

It is possible to sequentially expose the G optical image 19G and the B optical image 19B as one frame to the frames 19 ... At this time,
The top 19 has a length 1/3 that of the first embodiment.
Since it moves at a pitch of 0 mm, when the photosensitive recording medium 8 having an effective length of 270 m, which is the same as that in the first embodiment, is used, the imaging time is 15 minutes, which is three times that in the first embodiment.
