ABSTRACT:
A paper binder which removably secures a large number of pages of paper without injury to the paper, and which conducts binding so that it is easy to leaf through the pages. The paper binder comprises: a rectangular mount; a lever member extending in parallel with one edge of the mount and having one end rotatably supported at a corner portion of the mount; a spring member supported on the mount and having opposite ends one of which is fixed to the lever member so as to urge a free end of the lever member upward elastically; a pressing member attached to the other one of the opposite ends of the spring member so that the pressing member is elastically pressed in the direction toward the mount by an elastic force of the spring member to thereby grip a corner of paper disposed between the pressing member and the mount when the free end of the lever member is pressed downward against the elastic force of the spring member; and a locking member for locking the lever member when the free end of the lever member is pressed downward to maintain the lowered state of the lever member.
