Abstract: A plotter wherein, while a sheet is being moved on a recording surface, figures, characters etc. are automatically depicted on the surface of the sheet, or the contours of figures, characters etc. are automatically cut in the surface of the sheet. In the plotter, both the side edges of the sheet are respectively held between drive rollers and corresponding pinch rollers mounted at both the sideward parts of the recording surface in opposition to each other, and the drive rollers at both the sideward parts of the recording surface are rotated synchronously to each other, whereby the sheet is moved in the rotating direction of the drive rollers on the recording surface. Each of the drive rollers is formed at its peripheral surface with milling or ruggedness for preventing the sheet from slipping.
