Abstract
Abstract A paper binding machine is disclosed. A paper receiving frame having a channel-shaped section is secured to a base in an inclined manner. A paper binder is provided at the lower end of the paper receiving frame, while a guide frame is provided at the upper end of the paper receiving frame in such a manner that the lower end of the guide frame is disposed directly on the receiving frame. The guide frame inclined at substantially the same angle as the paper receiving frame is connected to a vibrating device, and a stopper for releasing the lower end of the opening of the paper receiving frame after binding has been completed such as to be capable of being freely opened and closed.
