Abstract
Description
【発明の詳細な説明】 本発明は複写機等のプラテンカバーに関する。[Detailed description of the invention] The present invention relates to a platen cover for a copying machine or the like.
従来、被写機のプラテンカバーには剛性のソフトなもの
と、・・−ドなものとがあったが、ソフト々も（Ｍｉカ
ウンターバランスをＮけられないので使い勝手が悪く、
最近のカバーはハードなものが大部分である。In the past, there were two types of platen covers for photographic devices: rigid and soft ones, and soft ones, but the software was not easy to use because the Mi counterbalance could not be adjusted.
Most covers these days are hard.
そして、この）・−トなプラテンカバーは第１図に示す

ｉｌｌｉ１ｆＣは升・淘度の高い白色フィルム３を結目
するように構成し、図示を省略した複写機のプラテン面
に対し、ヒンジを用いて開閉可能に増目けていた。As shown in FIG. 1, this platen cover is made by attaching a flat cushion 2 made of urethane resin or the like to the bottom of the cover 1, and
The illi1fC is constructed by tying together a white film 3 with a high degree of lamination, and is designed to be openable and closable using a hinge on the platen surface of a copying machine (not shown).

らの多数枚複写を継続する場合には更に大きくなる傾向
にあった。However, the hinges of the platen cover tend to play, and the white film is easy to get dirty, and when this dirt is wiped off, the smoothness tends to become even worse. Therefore, this platen cover is used in machines that use moving platens. If this happens, the cover may not be able to follow the movement of the platen due to inertia and may shift, and this shift will be transmitted to the original through the cushion, causing a defect that shifts the original and disrupts copy registration. This defect tends to become even more severe when multiple copies are made from a single original.
本発明は上記従来のプラテンカバーの欠陥に鑑みなされ

ずれの生じない複写機のプラテンカバーを提供すること
を目的とする。The present invention has been made in view of the above-mentioned defects of the conventional platen cover, and uses a flexible material such as soft rubber or urethane sponge as the material for the cushion added to the lower surface of the cover. By providing a hollow part of an appropriate shape in the cushion, the rattling of the hinge during copying is absorbed by the cushion, and the movement of the cover is prevented from being transmitted to the document placed on the platen. The purpose is to provide a platen cover for copiers that does not require a copy machine.
以下本発明を図面に示す実施例に基でいて詳細に説明す
る。The present invention will be described in detail below based on embodiments shown in the drawings.
第２図は本発明のプラテンカバーの一実施例を示す断面
正面図である。FIG. 2 is a sectional front view showing one embodiment of the platen cover of the present invention.

。Soft rubber is used as the material for the flat cushion 5 that is attached to the lower surface of the cover 4, and the cushion 5 is provided with a hollow portion 6,6, etc. having an appropriate shape, and the lower surface of the cushion 5 is A highly smooth white film T is pasted on the surface.
本発明のプラテンカバーはＶ、上のように構成したもの
であシ、次にその使用の状態をムービングプラテン複写
様の場合を例に挙げて説明する。The platen cover of the present invention is constructed as shown above.Next, the state of use thereof will be explained by taking as an example the case of moving platen copying.

９上に押圧する。As shown in FIG. 3, when the original 8 is positioned and placed on the platen 9 by the positioning plate 10 and the cover 4 is placed over the original 8, the cover 4 is placed on the lower cushion 5.
The hollow portions 6, 6, .

ることなく載置されていることになる。When the platen 9 is moved in the forward direction in this state, the cover 4 is also moved together with the platen 9 in the direction of movement. When the platen 9 is reversed and starts moving in the forward direction, the cover 4 is also reversed together with the platen 9. If there is play in the hinge at this time, the cover 4 will have inertia against the movement of the platen 9. Therefore, it may not be able to follow the movement and may shift. Conventionally, this shift when the cover 4 is reversed presses against its lower surface.
However, at this time, the cover 4 absorbs the movement by the cushion 5 on the lower surface and moves by the amount of play of the hinge, but this movement is not transmitted to the document 8. Therefore, the original 1'I8 is placed at the position ff' (positioned by the determining plate 10) without shifting.
本発明は以上のように構成し且つ使用するものであり、
前記クッション５の材料に柔軟性を有する材料を使用し
、しかもこれに適当な形状の中空部６．６・−一を設け
ることによって多少のヒンジのガタはほぼ完全に吸収す

ストレーションを正確に惺つことが可能となる利点があ
る。The present invention is constructed and used as described above,
By using a flexible material for the cushion 5 and providing hollow portions 6.6-1 of an appropriate shape in the cushion 5, any looseness of the hinge can be almost completely absorbed. Even if the platen cover is smooth, it has the effect of not shifting the original, and therefore the platen cover has the advantage that the original pressing surface, that is, the white film I, is easy to clean, and it is possible to accurately perform copy registration. be.
尚、本発明は上記実施例に限定されなければならない理

である。It should be noted that there is no reason why the present invention should be limited to the above embodiments, and for example, urethane sponge or the like may be used instead of the soft rubber as the material of the cushion 5.
7. Also, it goes without saying that the hollow parts 6, 6... of the cushion 5 may be formed by forming a hollow part t7I when the cushion 5 is extended to the cover 4 as shown in Fig. 4. It is.
更に本発明のプラテンカバーはムービンプラテンを使用
