Claim Text:
1. A sheet post-processing device that punches punch holes in a paper sheet and binds a stored paper sheet bundle, comprising: a conveying section that conveys the paper sheet; a punch section that punches the punch holes in the paper sheet conveyed by the conveying section; a stacker section that stores the paper sheet in which the punch holes are punched by the punch section; a stopper section that regulates a leading end of the paper sheet in a sheet conveying direction stored in the stacker section; a binding section that binds the paper sheet bundle whose leading end is regulated by the stacker section; and a folding section that folds the paper sheet bundle bound by the binding section at a predetermined folding position, wherein the punch section punches the punch holes at an upstream and downstream relative to the folding position in the sheet conveying direction at the conveying section, and the binding section binds the paper sheet bundle with a paper-made staple including leg portions and a connection portion connecting the leg portions, by positioning the connection portion to straddle across the folding position from the upstream to the downstream of the sheet conveying direction and the leg portions to penetrate the punch holes, and bending the leg portions inwardly to bind the paper sheet bundle.
