Abstract

PURPOSE:To discharge copies of different direction while avoiding mixing up by providing two paper discharge trays. CONSTITUTION:In a copying machine that increases copying speed by performing copying action by both foreward movement and backward movement of a scanning optical system, copies 19, 19' different in direction by 180 deg. are sent out sheet after sheet. To avoid mixing up, a copy 19 is taken out into the first tray 31 through a paper guide 26, and another copy 19' is taken out into the second tray 30. By combining first tray 31 and the second tray 30 into one, large sized copies that spread over two trays can be contained.

Description

【発明の詳細な説明】 本発明は光学系の往動、復動ともに画像形成ができる往
復読み取り装置用の排紙トレイに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper discharge tray for a reciprocating reading device that can form images in both forward and backward movements of an optical system.

動時のみ感光体上に画像形成するものであるかり、光学
系の復動時の移動時間がムダになるはかりでなく、時間
当りの複写枚数にも限朋がある。Copying machines that have been put into practical use for a long time form images on the photoreceptor only when the optical system moves forward, so the moving time of the optical system is not wasted when the optical system moves backward; There is also a limit to the number of copies.

伴ない劣化が促進される等の不都合が発生する。In order to increase the number of copies, there is a way to increase the moving speed of the optical system, but this gift will require only one image preview.
It is necessary to take various countermeasures such as increasing the strength of the transfer parts, increasing the run-up distance, reinforcing the main body structure, and increasing the output of the drive motor. As a result, the main unit becomes large and heavy, and it also makes noise. On the other hand, cleaning, charging, etc. accelerate the deterioration of the photoreceptor, and the developer also becomes more likely to scatter, resulting in disadvantages such as acceleration of deterioration due to high-speed agitation.

27 etc., an apparatus has been proposed that can increase the number of copies per unit time by reading images even when the optical system moves back and forth without increasing the moving speed of the optical system.

In some PCs, as shown in FIG. 1, the copy sheets 2 are stacked on the paper output tray L with the image orientations alternately different by 180 DEG.

トレイで受けるワラ法が提案されている。2. In order to improve the drawback that the orientation of the image of the copy paper ejected onto the paper ejection tray alternates by 180 degrees when the optical system associated with the above-mentioned device moves forward and backward, we have developed a practical application. Showa 56
No. 3,553 proposes a straw method in which two paper ejection trays are provided and the formed 8-overlapping copies are received in separate trays during the forward movement and the shaped copies are received during the backward movement.

This makes the space for placing the tray very small, which is very inconvenient when actually manufacturing an apparatus.

Image forming bag f for copying machines, etc. that produces a large number of copies per hour?
In this case, the first tray, which is fully loaded with copy paper during forward movement, and the second tray, which is fully loaded with copy paper during recoil movement, are almost on the same plane, and the stack of paper on the first and second trays is Alternatively, it is desirable to provide a copy sheet output tray which is flexible and, in the case of large sheets, can be loaded over the entire surface of the first and second trays.
