Abstract:
A cutting machine comprising:a placement portion on which a sheet is placed so as to be movable longitudinally thereof, the sheet having a length longer than a width; a sheet-driving unit for moving the sheet placed on said placement portion longitudinally; a detection sensor for detecting whether the sheet placed on said placement portion is present or not; a cutter unit movable in a direction perpendicular to the direction of movement of the sheet made by said sheet-driving unit; and a control unit for controlling said sheet-driving unit and said cutter unit, wherein said cutting machine operates both said sheet-driving unit and said cutter unit based on given input data to cut the sheet, and wherein said cutting machine calculates a length of the sheet necessary to perform a cutting operation based on said input data by means of said control unit, feeds out the sheet by said sheet-driving unit based on results of the calculation, and performs a given cutting operation based on said input data without fully returning the sheet fed out by said driving unit after said cutting machine detects whether the sheet of the necessary length found by the calculation is placed with using said detection sensor.
