Abstract: The cutting machine includes a sheet-driving unit, a detection sensor, and a cutter. The machine operates the sheet-driving unit and the cutter based on given input data to cut the sheet. The cutting machine calculates a length of sheet necessary to perform a cutting operation based on the input data, feeds out the sheet by the sheet-driving unit, and then performs a given cutting operation based on the input data without fully returning the sheet fed out by the driving unit after the cutting machine detects whether the sheet of the necessary length as calculated above is placed with using the detection sensor.

Abstract: In order to reduce an impact noise which is made when a pen lifting rail (5) is swung up into contact with a pen support arm (4) in a writing apparatus wherein the arm is swung up and down by swinging the rail up and down, in the present invention, immediately before the pen lifting rail (5) being swung up by de-energizing a solenoid, which is energized to swing down the rail, comes into contact with the bottom of the pen support arm (4), the solenoid is instantaneously energized to slow down the upward swinging of the rail to reduce the impact noise.
