うになつている。 A projection lens 29 is provided on the carriage 28 so as to face the recording medium 15 between the feed rollers 4 and 5. The projection lens 29 is formed by combining a front lens 29a and a rear lens 29b,
The distance between these lenses 29a and 19b is variable. Further, a reflecting mirror 30 is provided on the trolley 28.
The reflecting mirror 30 bends the optical path of the light emitted from the projection lens 29 and directs it toward the screen 31.

状の経路をたどつて回転される。 Next, the operation of this device will be explained. When the feed rollers 1, 2a, 3a, 4, 5, 6, 7a, and 8a are driven and rotated, the recording medium 15 is moved as shown by arrow A: feed roller 1 → between feed rollers 2a and 2b → idler 14 → feed Between rollers 3a and 3b → feed roller 4 → feed roller 5 → feed roller 6 → between feed rollers 7a and 7b → idler 13 → between feed rollers 8a and 8b → loop-shaped path of feed roller 1 traced and rotated.

される。 In the process of moving the recording medium 15 in a loop like this, the electrostatic recording head 18 records an electrostatic latent image on the recording medium 15 corresponding to the received image signal, and this electrostatic latent image is transferred to the developing device. It is visualized by 19. The received image visualized in this manner is conveyed to between the feed rollers 4 and 5, stopped at the same position, and enlarged and projected onto the screen 31 at the same position.

し投影レンズ２９を前後左右に移動できる。 Here, in order to enlarge and project the received image, light emitted from the projection light source 23 is focused by the Fresnel lens 22 and transmitted through the recording medium 15, and then passes through the projection lens 29 and the reflecting mirror 30 to the screen 31. However, in this device, the projection magnification can be changed by changing the focal length of the projection lens 29 by changing the distance between the front lens 29a and the rear lens 29b, and the carriage 26,
By moving the lenses 28 on the tracks 25 and 27, respectively, the projection lens 29 can be moved back and forth and left and right with respect to the recording medium 15 between the feed rollers 4 and 5.

できる。 Therefore, the entire received image is simply displayed on the screen 31.
In addition to narrowing the distance between the front lens 29a and the rear lens 29b, shortening the focal length of the projection lens 29, and increasing the projection magnification,
By moving the carts 26 and 28 to appropriate positions on the tracks 25 and 27, only the necessary portions of the received image can be enlarged to a high magnification and projected onto the screen 31.
このため、送信側から細かい文字や図形が送信
されて来た場合に、スクリーン３１から離れてい
る人にも容易に判読可能とすることができる。 Therefore, when fine characters or figures are sent from the sending side, they can be easily read even by a person who is far away from the screen 31.
前記のようにして１つの受信画の投影が終了
し、記録媒体１５が再び回転されると、投影終了
後の受信画はクリーナー２０および除電用コロナ
発生器２１を通過することにより消去され、同部
分の記録媒体１５は再び記録可能な状態となる。 When the projection of one received image is completed as described above and the recording medium 15 is rotated again, the received image after the projection is erased by passing through the cleaner 20 and the static elimination corona generator 21. The partial recording medium 15 becomes recordable again.

させることができる。 Note that in this embodiment, the feed rollers 3a,
By driving and rotating only the feed rollers 8a, 1, and 2a while keeping rollers 4, 5, 6, and 7a stopped, the recording medium 15 between the feed rollers 4 and 5 remains stopped.
Since only the recording medium 15 between the feed rollers 7a and 3a can be moved relative to the electrostatic recording head 18, the next received image can be recorded while one received image is being projected, and the device Operation efficiency can be improved.
なお、この場合、送りローラ７ａと静電記録ヘ

保持される。 In this case, the length of the recording medium 15 between the feed roller 7a and the electrostatic recording head 18 becomes gradually shorter. On the other hand, the electrostatic recording head 18 and the feed roller 3
Although the length of the recording medium 15 between the recording medium 15 and the recording medium 15 gradually increases, the idler 13 is moved in the direction of arrow B against the force of the spring 16, and the idler 14 is moved in the direction of the arrow C by the restoring force of the spring 17. As a result, the recording medium 15 in each section is maintained at a predetermined tension.
