気取入口及び排出口の構成に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image forming apparatus having a light source for irradiating an M document, a photoreceptor, and a fan arranged to exchange air within the apparatus. More specifically, the present invention relates to the configuration of the air intake and exhaust ports of the image forming apparatus.
従来の画像形成装置では、装置内の空気を入れ替えるご
とく配置されたファン近傍の外装に、空気取入用または
排出用の穴が設けられていた。In conventional image forming apparatuses, air intake or exhaust holes are provided in the exterior of the image forming apparatus near a fan arranged to exchange air within the apparatus.
ところが、装置内の空気を入れ替えるのにクロスフロー
ファンを用いた場合、または装置の制約により空気取入
口と排出口が密接して設けられた場合には、−度排出さ
れた空気が再び取り入れられてしまうため、著しく空気
入れ替え効率が低−下してしまう。However, if a cross-flow fan is used to exchange the air inside the device, or if the air intake and exhaust ports are placed close to each other due to device constraints, the air that has been exhausted will be taken in again. As a result, the air exchange efficiency is significantly reduced.
本発明による画像形成装置の空気取入口及び排出口の構
成は、前記取入口と前記排出口の間に排出された空気が
再び吸入されるのを防ぐごとく配置されたしきり構造を
有する事を特徴とする。The structure of the air intake port and the exhaust port of the image forming apparatus according to the present invention is characterized in that it has a barrier structure arranged to prevent the air discharged between the intake port and the exhaust port from being sucked in again. shall be.
本発明の上記の構成によれば、空気取入口と排出口の間
にしきり構造を有するため、排出された空気はしきり構
造に遮られて空気取入口より再び吸入されにくくなる。According to the above structure of the present invention, since the barrier structure is provided between the air intake port and the exhaust port, the discharged air is blocked by the barrier structure and becomes difficult to be sucked in again through the air intake port.
その結果、前記空気取入口からは常に新鮮な空気が取入
れられ、画像形成装置内の空気が入れ替えられる。As a result, fresh air is always taken in from the air intake port, and the air inside the image forming apparatus is replaced.

され画像形成に不要なマイクロカプセルを硬化させる。A lens 5 and an exposure table 6 are arranged below the original irradiation position C, and an unexposed photosensitive film 7 ejected from a cassette 20 is moved over the exposure table 6 in the direction of arrow E at the same speed as the i stacking table 3. Moving. Microcapsules containing a photocurable substance and a dye precursor are provided on the photosensitive film 7. The visible light reflected from the surface of the original 4 passes through a lens 5 and is then projected onto a photosensitive film 7 moving on an exposure table 6 to harden microcapsules unnecessary for image formation.

えられ、完成された画像として装置外へ排出される。The exposed photosensitive film 7 is sent to a pressure developing mechanism 30 located below the exposure table 6. On the other hand, the transfer paper 41 is also sent out from the transfer paper cassette 40 and conveyed to the pressure developing mechanism 30. The exposed photosensitive film 7 and the transfer paper 41 are overlapped and pressed between pressure rollers 31 and 32 in the pressure development mechanism 30. As a result, the photosensitive film 7
The upper uncured microcapsules are crushed and a colored image is formed on the transfer paper 41. After pressure development, the photosensitive film 7 is returned to the cassette 20 and wound up. On the other hand, the transfer paper 41 is sent to a heat treatment means 50, where the development reaction is accelerated by heating and the surface is made glossy, and the paper is discharged from the apparatus as a completed image.
前記ハロゲンランプ１からは多くの熱線が放射されるの

空気取入口１１への流入をより一層抑える事ができる。Therefore, a part of the outside air taken in from the air intake port 11 is blown by an axial fan 9 to cool the halogen lamp 1, the concave reflector 2, the infrared absorption filter 8, etc. The air that has become high temperature due to cooling is The air passes through the exhaust duct 12 and is mixed with a portion of the air taken in from the air intake port 11 by the cross flow fan 10, and is discharged from the exhaust port 13 after lowering the temperature. 14 is a baffle plate through which the warm air discharged from the outlet 13 is returned to the air intake 1.
By making the lower surface of the partition plate 14 convex upward, the air discharged from the outlet 13 flows downward along the convex surface, which prevents the air from being inhaled from the air intake port 13. 11 can be further suppressed.

The rectifying plate 16 of the section #I! is arranged so as to take in the air above the image forming apparatus, and the rectifying plate 16 of the discharge port 13 section is arranged so as to take in the air above the image forming apparatus. By arranging the forming device so that air is discharged below it, intake and exhaust can be separated. Similar effects can be obtained even when the baffle plate 16 is provided only at either the air intake port 11 or the air outlet port 13.
