Abstract
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.
