Claims

[Scope of utility model registration request]

In a body opening/closing mechanism of a copying machine configured such that an upper movable part is rotatably supported by a lower fixed part and the upper movable part is rotated upward by a reaction force of a compression spring, the rotation of the upper movable part A body opening/closing mechanism for a copying machine, characterized in that the distance from a fulcrum to a point where the reaction force of the compression spring is applied to the upper movable part can be changed.
