It is an object of the invention to bind recording papers at a desired position, and produce a stapled sheaf of recording papers efficiently. The recording paper fed in the feeding direction by conveying rollers is held by a support plate so that a downstream end in the conveying direction thereof abuts against a predetermined gate projecting from a holding face of a support plate by a paddler. Mutually opposite ends parallel to the conveying direction are aligned by joggers. When a predetermined number of recording papers are held in stuck, upper and lower stapling units separately provided with the support plate between them are put in action, and a staple is driven from a surface of the recording paper. A tip portion of the staple projecting from the other surface of the recording paper is bent by a clinching member of the lower stapling unit. A stapled sheaf of recording papers is discharged in the discharging direction parallel to the feeding direction.
