経て装置外の排出トレーへと排出されている。Here, explanation will be given using a copying machine as an example. As is generally known, in a copying process system, copy paper on which a document image has been visualized using a developer is conveyed to a fixing device by a sheet conveying means disposed within the device, where it undergoes a fixing process. After that, it is discharged to a discharge tray outside the device.

後の案内ガイドを小さくし紙との接触領域を少なくシ、
水蒸気の拡散効果を大きくすることが提案されている。However, in general, the fixing process for fixing a developed image onto a sheet as a recording material involves heating roller 2, as shown in FIG.
The fixing device 1 has a combination of a pressure roller 3 and a pressure roller 3, and the heating temperature is set to a high temperature of about 200°C.
This is extremely different from the outside environment. For this reason, if there is a significant temperature difference between the fusing temperature and the outside temperature, dew condensation will occur on parts around the fuser, and especially if dew condensation appears on the conveyance guides before and after the fuser, which is the sheet conveyance means, the conveyance will be interrupted. The water droplets will adhere to the sheet that has been brought in, making the copy paper wet with water, and in the worst case, the original image on the copy paper will bleed and become difficult to read. To prevent this, Japanese Patent Application Laid-Open No. 51-68836, t\j Publication No. 54-
As described in 96049, the guide immediately after the fixing roller is made smaller to reduce the contact area with the paper.
It has been proposed to increase the diffusion effect of water vapor.

又これら公報に記載される以前から定着ローラ対から排
紙ローラとの間においては紙から発生する水蒸気の拡散
が行れている。Further, water vapor generated from paper has been diffused between the pair of fixing rollers and the paper ejection roller since before these publications.

一方、近来特開昭５１−６８８３６号公報に記載される
ような両面複写や多重複写が行われる装置においては、
記録材の搬送を直接外部へ行うことと、装置内で所定方
向に行うこと（循環パス）の両方の切換えで達成するも
のが提供されている。On the other hand, in a device that performs double-sided copying or multiple copying as recently described in Japanese Patent Application Laid-Open No. 51-68836,
There is a method that achieves this by switching between conveying the recording material directly to the outside and conveying it in a predetermined direction within the apparatus (circulation path).

ところが、このように装置内で加熱定着後の紙を所定方
向に搬送するものでは、前述の案内ガイド域を通過した
後に長い搬送路中を移動しなければならない。すると、
ガイド部での十分な水蒸気の拡散があるにもかかわらず
、長い搬送路内では部分的又は局部的に集中する水蒸気
が露結してしまうという新たな問題が生じた。However, in such an apparatus in which the paper after heat-fixing is conveyed in a predetermined direction within the apparatus, the paper must be moved through a long conveyance path after passing through the above-mentioned guide area. Then,
Despite sufficient water vapor diffusion in the guide section, a new problem has arisen in that water vapor that is partially or locally concentrated in a long conveyance path becomes dew-condensed.

この露結による水滴は搬送路内で不均一であるため、搬
送抵抗が部分的に大きく異なり、斜行搬送を起こす。こ
の斜行は多大なもので記録材か搬送路中で停止するとい
うジャムとなってしまう。Since the water droplets due to dew condensation are non-uniform within the conveyance path, the conveyance resistance varies greatly depending on the area, causing oblique conveyance. This skew is so great that the recording material stops in the conveyance path, resulting in a jam.

ことに、この現象は多重記録や両面記録にとっては致命
的であり、そのジャム処理も容易でない。In particular, this phenomenon is fatal for multiple recording or double-sided recording, and it is not easy to clear the jam.

又、長い搬送路が装置の外カバーの如き外壁に近い場合
は、その露結が多大で、上記提案の如き案内ガイド部で
水蒸気を拡散しても、外壁からの低温域の影響で、搬送
路中に大きな変化に豊んだ温度分布を形成してしまうた
め解決できなかった。In addition, if a long conveyance path is close to an outer wall such as the outer cover of the device, there will be a large amount of dew condensation, and even if the water vapor is diffused by the guide section as proposed above, the conveyance will be affected by the low temperature range from the outer wall. This problem could not be solved because it would create a temperature distribution with large variations throughout the road.

特に、連続多重記録や連続両面記録においては枚数が増
えるに従って、ジャム発生率も高くなシ、商品メリット
を半減してしまっていた。In particular, in continuous multiplex recording and continuous double-sided recording, as the number of sheets increases, the jam occurrence rate also increases, reducing the product's merits by half.

（目　的） 本発明は上記目的を解決することであり、ジャム発生率

写紙の品質を向上させている。In this example, a plurality of holes are made in the double-sided (multiple) conveyance guide surface immediately after fixing, and a plurality of holes are also made in the outer cover, so that a state close to the outside air environment is constantly maintained in the sheet conveyance path inside the apparatus. This prevents dew condensation and improves reliable paper feeding and copy paper quality.

録材を導ひく。When conveying the recording material to the outside of the apparatus, the switching means 17 is located below as shown by the broken line, and the guide 111, the paper ejection roller pair 8,
When discharging with 9 and conveying to the inside of the device, switch means 1
7 is located above as shown by the solid line. The conveyance path 20 is close to the outer cover 14, which is the outer wall of the apparatus, and is a substantially parallel portion facing vertically downward, and guides the recording material to different predetermined portions.

小さくできる。The conveyance path 20 has a plurality of cutout openings (c) as a characteristic feature of the present invention, and allows air to flow into the conveyance path 20. The water vapor generated in the conveyance path 20 is diffused by the openings (c), and at the same time, the recording material is air-cooled, so that the generation of water vapor is suppressed. As a result, the area in which the openings C are provided can be made small, and the heat dissipation area of the recording material can also be made small.

Also, a plurality of openings d are provided. This allows the air inside the device and the outside air to flow freely into or out of the device through these notches, removing hot air from the fuser and moist air from evaporated oil and water during the fusing process. Air flows out. therefore,
The temperature difference between the outside air temperature and the temperature around the fixing device is alleviated, and dew condensation on the guide plate surface can be prevented. Furthermore, the presence of notches in the guide plate itself reduces the area on which water droplets adhere, significantly reducing the number of water droplets compared to a guide plate without notches. In addition, as is clear from FIG. 2, the notch openings a and ble in the embodiment of the present invention have a real elongated hole shape centered on the axis tilted by ±0 with respect to the direction of the arrow in the paper advance direction. The center of the negative change is located approximately at the center of the paper width. Furthermore, any value of θ can be selected as long as it is between 00 and 30 degrees. However, the closer the angle is to 0°, the farther away from the edge of the paper the notch should be provided. In addition to the real elongated hole, the notch shape is triangular, base-shaped, and teardrop-shaped (Fig. 4 (a), (b)
), ((ri'), and other various shapes can improve paper feeding υ reliability.The shapes of the notches d and e on the exterior cover should be determined from a design perspective; There is no such thing as good.

Alternatively, it may be formed with a lip guide (furthermore, it may have an opening f at the top of the notch) as shown in the side and perspective views of FIGS. 6 and 7. . Furthermore, it is preferable to integrate it with the exterior cover or form it into a guide 141 (it is even better if it has a cutout upper opening V), since the strength will be improved and the air flow will be more reliable.
