ABSTRACT:
A sheet cutting apparatus including an air removing mechanism and a sheet overlap preventing mechanism. The air removing mechanism includes an aligning device for pushing edges of a stack of sheets, which stack is placed on a table before being cut, towards a center of the stack to align the edges of the stack, and a cover member for covering the stack on the table such that the stack can be hermetically sealed, a pushing device for pushing the stack form above, and an evacuation device for removing air from a space between the table and the cover member to hermetically seal the space. The sheet overlap preventing mechanism is provided with a first restriction device for restricting a displacement of a plurality of stacks of cut sheets, with respect to a thickness direction of each of the stacks of cut sheets, and a second restriction device for restricting a displacement of portions to be cut off from the stacks of the cut sheets, with respect to a thickness direction of each of the portions to be cut off.
