| 1. A sheet-trimming apparatus for trimming a sheet located in a trimming position, the sheet-trimming apparatus comprising:
a trimming blade to trim a sheet which has been substantially horizontally located in the trimming position;
a blade-driving mechanism structured to bring said trimming blade into contact with said sheet from under a surface of said
sheet and to move said trimming blade in a trimming direction to trim said sheet located in said trimming position;
a blade-receiving member to receive said trimming blade on an upper surface of said sheet, said blade-receiving member being
formed into a plate and being positioned at a first position such that said trimming blade contacts said blade-receiving member
at a first portion of said blade receiving member;
a blade receiving-member driving mechanism structured to shift said blade-receiving member relative to said trimming blade
so that said blade-receiving member can be positioned at a second position such that said trimming blade contacts said blade-receiving
member at a second portion of said blade receiving member; and
a sheet-holding member traveling between a working position where said sheet-holding member holds said sheet at the trimming
position and a retreated position;
wherein said blade-receiving member is structured to be movable relatively with said sheet holding member by said blade-receiving
member driving mechanism; and
wherein a part of the sheet-holding member is composed of the blade-receiving member.
