Claim:
A bookbinding apparatus comprising: an input unit configured to input image data of multiple pages; a printing unit configured to subject multiple sheets to print processing based on the image data of multiple pages input by the input unit; a stacking unit configured to stack the multiple sheets subjected to print processing by the printing unit as a sheet bundle; a paper-feed unit configured to feed a cover sheet; a bookbinding unit configured to perform a binding process for generating a book by binding the cover sheet to the sheet bundle; a mode setting unit configured to set one of a right-opening bookbinding mode for performing the binding process which generates a right-opening book and a left-opening bookbinding mode for performing the binding process which generates a left-opening book; a rotating unit configured to execute rotating processing for changing the top and bottom directions of the image data so that a first direction of the image data in the right-opening bookbinding mode and a second direction of the image data in the left-opening bookbinding mode are opposite; and a notification unit configured to notify, before the binding process is started by the bookbinding unit, an operator of the bookbinding apparatus that it is necessary to change the top and bottom directions at the time of loading the cover sheet to the paper-feed unit in a case where the mode setting unit has set the left-opening bookbinding mode so as to match the top and bottom directions of a sheet bundle stacked in the stacking unit and the to and bottom directions of the cover sheet, wherein the notification unit does not notify the operator of the book binding apparatus that it is necessary to change the top and bottom directions at the time of loading the cover sheet to the paper-feed unit in a case where the mode setting unit has set the right-opening bookbinding mode.
