れていた。2. Description of the Related Art Conventionally, a document crimping plate in an image reading apparatus or the like is rotated around a hinge portion so that a crimping position at which a document placed on a document is crimped and a crimping of the document are released to an upward direction. It is configured to be openable and closable between an open position where it stops in the open state. And, the hinge part is Japanese Patent Sho 59
-A damper as shown in No. 26013 etc. is provided, and the force of the spring of the damper part and the weight and center of gravity of the original pressure plate can be balanced according to the angle when the original pressure plate is opened. It was configured to stop at various angles.

きすぎたりすることになる。However, in the case of the above-mentioned prior art, since the weight of the original pressure plate is balanced with the spring pressure of the damper to stop the original pressure plate in the opened state, the spring pressure is The weight and the position of the center of gravity of the original pressure plate had to be set accurately. Therefore, when the original pressure plate is enlarged in order to accommodate a large-size original, the change in weight due to variations in the specific gravity of the material of the original press plate becomes large, and it becomes difficult to balance the spring pressure of the damper. There was a problem. For example,
If the original pressure plate is too heavy, the spring pressure of the damper will be lost and it will not be possible to stop the original pressure plate in the open state, and it will close when the user releases his hand.If the original pressure plate is too light, The pressure of the spring of the damper becomes relatively strong, so that the original pressure plate cannot stop at the position where the original is pressed, or it opens too much.
