Abstract

PURPOSE:To discharge the fume due to toner scattering and toner fusion which are generated when a flash lamp emits the light, from between the lamp and a form in a copying machine, a printer, or the like the electrophotographic system. CONSTITUTION:A table 8 where a form 1 is guided is covered with a pre-fixing cover 4 and a post-fixing cover 6 to form a discharge chamber 9 between a flash fixing part 5 and the table 8 where the form 1 is guided toward the position just under the flash fixing part 5, and a discharge hole 10 is opened on the post-fixing cover 6, and the scattered toner and the fume of the fused toner which are generated on the surface of the form are discharged through this discharge hole 10. It is undesirable that the discharge hole 10 is provided just before the fixing part 5 because the scattered toner is increased to generate easily the disorder of printing. This discharge toner fume is discharged to the outside of the device through a filter, a deodorizing machine, etc.

Description

【発明の詳細な説明】 呆発明は電子写真方式たよる複写機、プリンター等にお
けるフラッシュ定着装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flash fixing device for electrophotographic copying machines, printers, and the like.

従来フラッシュ装置を用紙上に形成されたトナ可視像の
定着装置として使用した場合、フラッシュランプの発光
時にトナー飛散及びトナー融解による発煙が生じ、これ
が原因となってトナーの定着性の劣化及び発光音の増大
というトラブルが発生していた。Conventionally, when a flash device is used as a fixing device for a visible toner image formed on paper, when the flash lamp emits light, toner scatters and smoke is generated due to toner melting, which causes deterioration of toner fixability and light emission. There was a problem with increased sound.

引・緋気することによって前記欠点を解決し、定着の安

特徴とするものである。The present invention solves the above-mentioned drawbacks in a flash fixing device by suctioning/scorching air from scattered toner and toner melting generated when a flash lamp is emitted, thereby achieving stable fixing and low noise of the device. It is characterized by this.

以下、本発明の一実施例を図面によって説明する。An embodiment of the present invention will be described below with reference to the drawings.

ーキである。The paper 1 on which the toner visible image has been formed is conveyed through the loop tension 2 along the table 8 to just below the flash fixing section 5, where the toner is melted by the flash fixing section 5 and the toner visible image is formed on the paper 1. After fixing, the paper 1 is discharged by the discharge roller 7. 3 is a paper brake.

しやすくなるため好ましくない。なお、この排気トナー
煙はフィルター、脱臭機等を経由後装置外へ排出される
。The present invention covers the upper part of the table 8 that guides the paper 1 with a pre-fixing cover 4 and a post-fixing cover 6, and provides a space between the flash fixing section 5 and the table 8 that guides the paper 1 directly below the flash fixing section. After fixing, an exhaust chamber 9 is formed in the cover 6, and an exhaust port 10 is opened in the cover 6 to exhaust scattered toner and melted toner smoke generated on the paper surface through the exhaust port 10. In this case, it is not preferable to provide the exhaust port 10 immediately before the fixing unit 5 because the amount of scattered toner increases and printing becomes more likely to blur. Note that this exhaust toner smoke is discharged to the outside of the apparatus after passing through a filter, a deodorizer, etc.

本発明は以上説明したように、フラッシュランプ発光時

煙をランプと用紙との間から排気するようにしたので、

性の低下を防止できる。As explained above, in the present invention, the scattered toner generated when the flash lamp is emitted and the smoke generated by toner melting are exhausted from between the lamp and the paper.
The lamp, lamp front hood, etc. are prevented from getting dirty, and deterioration in fixing performance caused by dirt on the lamp and hood, scattered toner, etc. can be prevented.

また飛散トナー及びトナー融解煙が常に排気されている
ことによって発光音がいつも最低に押えられ、装置の低
騒音化を図ることができる効果を有する。Furthermore, since the scattered toner and toner melting smoke are constantly exhausted, the emission sound is always kept to a minimum, which has the effect of making it possible to reduce the noise of the apparatus.
