Claims

[Scope of utility model registration request]

This is a document holding device for strongly pressing the document set on the document table of a copying machine, and the holding force is based on the own weight of the document holding device main body, the document holding device main body side, and the copying machine main body side. and the traction force of a coil spring each having a locking fulcrum,
When the final copy is completed, the fulcrum is moved so that the coil spring's locking fulcrum on the copying machine main body side is automatically moved after the exposure cycle is completed so that the direction of action of the coil spring is reversed. What is claimed is: 1. A document holding device comprising a mechanism so that the document holding device is automatically released by movement of a locking fulcrum on the copying machine main body side.
