摘要

A sheet sorting machine for sorting plural sheets to plural groups and stapling the sheets by the group. The sheet sorting machine has a sorting assembly to convey the sheets to the plural bins by the group; a positioning member to true up the sheets to a setting position in each of the bins; a member to fix the sheets in the bins; oscillator to move the bins, holding the sheets at the setting position in the bins, to a stapling position; and stapler to staple the sheets at the stapling position; in which the fixing member fixes the sheets before the oscillator sets the sheets to the stapling position.
