A stapler apparatus of the type using continuous belt-formed staplesincludes a staple feed clawfor advancing the staplessequentially to a stapling positionand a drive meansfor driving the staplesdrawn to the stapling positionA clincher meansbends the ends of the staplesdriven into the sheets and pivots a staple feed pawlinterlocked to the staple bending operation of the clincher meansfor sequentially feeding the staplesto the stapling positionThis construction lightens the load on the drive means to staple sheet stacks, facilitates smooth driving operation of the drive means, and reduces the occurrences of trouble.

Stapling apparatus with interconnected feeding and clinching

A stapler apparatus includes a cartridge that stores staples, a staple driving unit for engaging and driving staples, an urging member to urge the cartridge toward the staple driving unit, and an interlocking mechanism movable upon installation of the cartridge to apply the urging member to the cartridge. The construction provides a stapler apparatus that allows the easy mounting of a cartridge and that can effectively urge a cartridge toward the punching station of the stapler.

Stapler device

A staple storage unit () allows the effective and easy removal of jammed staples () from the inside of the apparatus () by attracting jammed staples to the staple storage unit. The staple storage unit can be removed from the stapler apparatus frame. The staple storage unit is detachably mounted to a stapler apparatus provided with a storage unit () storing staples and a guide unit () to guide staples in this storage unit to a staple driving unit (). The stapler includes staple attracting member () in the apex of a staple driving unit on the guide unit ().

Staple attracting member for attracting jammed staples

A stapling device for automatically binding a set of sheets is formed of a needle driving unit for driving a needle in the set of the sheets; a bending unit for bending the driven needle; two pairs of front and rear guide shafts for supporting the needle driving unit and the bending unit and guiding movements of these units in a sheet width direction; and moving shafts for moving these units along the guide shafts in the sheet width direction. By disposing each moving shaft between the front and rear guide shafts, each unit can be moved in the sheet width direction stably and smoothly, and the entire device can be structured small. Also, in at least one of the units, a small space is formed for a moving mechanism for at least one of needle driving device and bending device in a sheet thickness direction, to thereby achieve a further miniaturization of the entire device.
