【考案の詳細な説明】
本考案はコンタクトガラスが摺動するようになっている
複写機の原稿台装置に関するもので、その目的とすると
ころは各部品の寸法精度を高くしなくても軽く摺動でき
、又コンタクトガラスの片側を誤操作により持ち上げて

た。Conventionally, as shown in FIG. 1, a U-shaped holder 2 is fixed to one side of a transparent contact glass 1, and the bottom 2a of the holder 2 is
A roller guide rail 4 is fixed with screws 3 to the roller guide rail 4, a roller guide rail 6 is fixed to the lower surface of the upper part 5a of the side plate 5 facing the roller guide rail 4, and a large number of rollers 7 are fitted between both roller guide rails 4 and 6. The lower surface of the other side of the contact glass 1 is placed on a guide member 9 fixed to the upper part of the side plate 8, and the contact glass 1 is slidable along the fixed roller guide rail 6. Although manuscript table devices are well known,
If the dimensional accuracy of the holder 2 is even slightly off, an unreasonable force will be applied to the roller guide rail, making it difficult to slide. Therefore, the dimensional accuracy of the holder 2 must be made highly accurate, resulting in high processing costs, and contact When the glass was placed in the home position protruding to one side from the copying machine body, if the protruding end of contact glass 1 was lifted upward by mistake, excessive force was applied to contact glass 1, causing damage to the recolo guide rail. This had the disadvantage that it bent and the sliding movement became unsmooth.
本考案はコンタクトガラスと一体に固定した保持体に弾
性体を介してコロガイドレールを取り付け、コンタクト
ガラス及びコロガイドレールに無理な外力が作用しない
ようにして従来の欠点を除くようにしたものである。This invention eliminates the drawbacks of the conventional method by attaching the roller guide rail via an elastic body to a holder that is integrally fixed to the contact glass, thereby preventing excessive external forces from acting on the contact glass and the roller guide rail. be.

A large number of rollers 7 are fitted between the rails 6 and 11, the other lower surface of the contact glass 1 is placed on a guide member 9 fixed to the upper part of the side plate 8, and the contact glass 1 is guided along the fixed guide rail 6. It is designed so that it can be slid.

破損を防止することができる。According to the present invention, a holder is fixed to one side of the contact glass, a roller guide rail is placed on the bottom of the holder via a spring, and a screw is loosely fitted into the center hole of the spring and the roller guide rail. The lower part is screwed and fixed to the holder, and a large number of rollers are fitted between it and the roller guide rail fixed to the side plate so that it can slide, so there is no need to apply excessive external force to the holder due to dimensional errors or incorrect operation. Even if the force is applied, the spring absorbs it and no unreasonable force is applied to the contact glass and the roller guide rail, so the accuracy of the holder can be lowered, processing costs can be lowered, and sliding operation can be made smoother. Breakage of the contact glass due to erroneous operation can be prevented.
なおばねの代りに他のどのような弾性体を用いてもよい
。Note that any other elastic body may be used instead of the spring.
