Abstract
A binder that can be opened/closed relatively easily by manually handling the tops of binding rings includes a holding member having a sufficient length to allow binding rings to be arranged with a spacing therebetween, and an operating member fixed movably to the inner side of the holding member such that the binding rings anchored to the surface thereof are fixed to the holding member. The operating member includes a pair of operating pieces movable along the longitudinal direction of the holding member within the holding member, and a pivot shaft formed along the abutting edges of the pair of operating pieces. Further, an opening/closing member is provided to move the operating pieces within the holding member in the longitudinal direction of the holding member while rotating the pair operating pieces around the pivot shaft in the directions to open the binding rings.
