Sheet-cutting device, method for cutting sheet, and non-transitory computer readable recording medium

A sheet processing apparatus comprising:

• a first processing section which forms a plurality of first processing lines, extending in a first direction (an X axial direction) on a sheet as an object to be processed by selectively making a plurality of tools contact with and release from the sheet, and relatively moving the plurality of tools to the first direction with respect to the sheet, at a first position, the plurality of tools comprising a plurality of first blades to cut the sheet;
• a second processing section which forms a plurality of second processing lines, extending in a second direction (a Y axial direction) orthogonal to the first direction on the sheet by selectively making a plurality of tools contact with and release from the sheet and relatively moving the plurality of tools to the second direction with respect to the sheet, at a second position, the plurality of tools comprising a plurality of second blades to cut the sheet;
• a third processing section which forms a third processing line that is an aslant line or a curved line, on the sheet, by making a third blade contact with and release from the sheet, and relatively moving the sheet and the blade, at a third position, the blade being configured to cut the sheet;
• a conveyance mechanism which conveys the sheet among the first position, the second position, and the third position;
• an up-down moving motor which causes a movement of the blade which cuts the sheet in a third direction (a Z axial direction) orthogonal to the first direction and the second direction;
• and
• an angle adjustment motor which causes a rotation of the blade about an axis along the third direction,
• wherein the first processing section, the second processing section, and the third processing section are operable independently of each other and in parallel.
