Description

[Detailed Description of the Invention] The present invention relates to an autoprocessor in which a developing device is mounted on an exposure device, and in particular, the arrangement of the photosensitive material box and its stock box in the photosensitive material setting chamber of the developing device, and the arrangement of the photosensitive material box and its stock box. Concerning containment structure.

In order to perform exposure and development in one device and to reduce the area occupied by the device, it is conceivable to mount and fix the developing device on the exposure device.

By the way, it is troublesome to put a photosensitive material into the photosensitive material setting chamber of the developing device each time a negative material or other photosensitive material is set for exposure or sent to the transfer system, so a photosensitive material box is placed inside the photosensitive material setting chamber. However, since such a setting chamber is in a bright room during exposure, it is necessary to take measures to prevent other photosensitive materials in the photosensitive material box from being exposed, and it is also easy to put in and take out photosensitive materials. It is preferable to make it possible to do so.

On the other hand, when the photosensitive material box provided in the setting chamber becomes empty, it is not desirable to put the photosensitive material that needs to be replenished into the setting chamber as it is in order to prevent exposure to light.
It is desirable to store a stock box for photosensitive material in and out of the setting chamber, and it is also necessary to keep the storage space for the stock box in a dark room. It is necessary to take measures to make replenishment work easier.

This idea was created in view of the above circumstances.
The purpose of this is to prevent light from entering the photosensitive material box that should be provided in the photosensitive material setting chamber of the developing device, and to make it easy to take in and take out the photosensitive material. To keep the storage space of the stock box for the photosensitive material to be stored in a dark room condition to prevent light from entering the box, and to facilitate replenishment of the photosensitive material from the stock box to the photosensitive material box, A further object of the present invention is to provide an autoprocessor that achieves the above with a simple structure.

In order to achieve such an object, the present invention has a light-sensitive material box that opens forward and is fixedly suspended from the upper wall of the light-sensitive material setting chamber of the developing device mounted on the exposure device, and a light-sensitive material box that opens forward is fixed to the upper wall of the light-sensitive material setting chamber of the developing device mounted on the exposure device. A self-gravity hinged lid that can be opened and closed is attached to cover this opening at all times, and a support plate that also serves as a light shielding plate that is tilted forward is placed at the back of the set chamber. The gist is that a stock box for photosensitive material is housed in a darkroom-like space on the back side, which can be taken in and out from the front.

After passing through the outlet section 84, it is sent to the squeezing rollers 92, 92 above it, and this squeezing roller 9
No. 2, 92, both emulsion surfaces are sandwiched from left and right and are superimposed in close contact.

Both sheets of paper, which are in close contact with each other, are fed vertically into the diffusion transfer chamber 93 in a vertical state, and the upper ends are fed into the upper guide passage 97 while being held between the dispensing rollers 96, 96, and the actuator 98a of the limit switch 78 is moved. When you press , motor 2
8 input circuit is turned OFF, and the dispensing roller 9
6,96 stops. This dispensing roller 96,
Both papers, whose upper portions are held by 96, stand still in the diffusion transfer chamber 93 in a vertical position, and are held there for a preset time to allow the desired diffusion transfer reaction to occur in the diffusion transfer chamber 93, which is a dark room. It will be done.

After the required time has elapsed, the input circuit of the motor 28 is turned on again, and the two papers that have undergone the diffusion transfer reaction are driven by the dispensing rollers 96, 96, pushing up the light-shielding cover 25 placed over the dispensing port 24, and pushing up the upper plate of the casing 11. It is paid out on 21.

By manually peeling off both papers thus discharged, a photocopy image transferred to the emulsion side of the positive paper is obtained.

In the autoprocessor that can perform exposure and development in one unit as described above, in the present invention, the exposure device 1
A photosensitive material box 35 having a forward opening 35a is fixedly suspended from the upper wall 32 in the photosensitive material setting chamber 30 of the developing device 10 placed above, and an opening/closing box 35 is hinged at the upper side to the opening 35a of the box 35. Since a self-adjustable lid 36 is attached, the opening 35a is always closed by the lid 36, preventing light from entering the box 35. Furthermore, the automatic lid 36 can be opened simply by pulling it open. Photosensitive materials can be easily taken in and out. Furthermore, a support plate 101 which doubles as a light shielding plate is arranged in the back of the setting chamber 30 and is tilted forward, and a sufficient space is formed between the plate 101 and the box 35, and the support plate 101 is tilted forward and serves as a light shielding plate. Since the photosensitive material stock box 102 is accommodated on the back side, the storage space for the stock box 102 is limited to the support plate 1.
This creates a dark room-like space on the back side of the stock box 102, which prevents light from entering the stock box 102 through the opening 102a, and also makes it possible to replenish the photosensitive material from the stock box 102 to the photosensitive material box 35. It's easy to do and it's easy to use stockbox 10.
The second support plate 101 can be moved in and out of the rear space, and the above effects can be achieved with a simple structure that only requires the lid 36 and the support plate 101.

According to the present invention, the above-mentioned great advantages can be exhibited.
