Abstract
PURPOSE: To pressure hold the original always surely by making an original pressure plate vertically movable by way of an elastic material.
CONSTITUTION: A plate 3 is fixed by means of screws 4 to the inner side at one end of an original pressure contact plate 1. The plate 3 is fixed rotatably to a mounting seat 6 by way of a fulcrum axis 5. A rotating leg 8 is mounted to the mounting seat 6 via fulcrum axis 7 and a guide shaft assembled with a spring washer 10, slide spring seat 11 and coil spring 12 is fixed to the rotating leg 8. On the other hand, the mounting seat 6 is fixed to the top end of the stanchion 16 which is supported slidably in the vertical directions with respect to the support member 15 fixed to the body 14 side and is assembled with a roughly wound coil spring 17. Then, when the original is a sheet, it is pressure-held onto the glass plate 23 by way of a cushion member 2 and when it is a three-dimensional original, the stanchion 16 floats by overcoming the force of the coil spring 17 and the original is pressure-held onto the glass plate 23.
