摘要：
A punching apparatus having a punching member which effects punching on a sheet, and a driving mechanism which moves the punching member in a sheet width direction intersecting with a sheet conveying direction. On the basis of the difference between the position of a current sheet and the position of a next sheet succeeding thereto detected by a detecting sensor which detects the position of each conveyed sheet in the sheet width direction, at a position upstream of the punching member, the punching member is moved by the driving mechanism along the sheet width direction from a punching position for the current sheet to a punching position for the next sheet.
