Sheet accommodating apparatus and sheet binding apparatus

摘要

A sheet accommodating apparatus includes sheet accommodating means for accommodating one by one sheets fed thereto; aligning means for aligning the sheets; sheet interval detecting means for detecting interval time or distance between adjacent sheets; and control means for preventing the aligning means from operating when an output of the sheet interval detecting means indicates that sheet interval time or distance is shorter than time required for the aligning means to align the sheets or the distance through which the sheets moves in the time required for the aligning means to align the sheets.
