Abstract:
1. A binding apparatus comprising: a binding mechanism for binding a plurality of sheets between a stitcher section and a clincher section with a staple needle, said binding mechanism being equipped with said stitcher section including a staple needle storing section and a needle pushing out section and with the clincher section for bending one end of said needle in a separate manner; first and second supporting members for guiding said stitcher section and said clincher section to support said binding mechanism in a parallel manner; and moving mechanisms for moving said binding mechanism along said supporting members; wherein first and second position controlling members are pair-wise disposed and each are configured to limit the position of said binding mechanism around each of said first and second supporting members as a center thereof, wherein said supporting members and said position controlling members are interposed between side plates to form a housing, wherein the stitcher section has a pair of first rollers which are provided in a side of the stitcher section in a direction where the sheet is fed to limit the rotation of the stitcher section around the first supporting member, a substantially planar portion of the first position controlling member being disposed between the first rollers, wherein the clincher section has a pair of second rollers which are provided in a side of the clincher section in the direction where the sheet is fed to limit the rotation of the clincher section around the second supporting member, a substantially planar portion of the second position controlling member being disposed between the second rollers, wherein a portion of an attaching surface of the first position controlling member has at least two sides of different lengths, a longer of the two sides of the first position controlling member is aligned in a direction approximately perpendicular to a longitudinal axis of the side plates facing the position controlling members, and a portion of an attaching surface of the second position controlling member has at least two sides of different lengths, a longer of the two sides of the second position controlling member is aligned in an approximately parallel direction to the longitudinal axis of the side plates to which the second position controlling member is attached, and wherein said position controlling members have a substantially U-shaped cross-section that provides a channel to house a part of the binding mechanism.
