<p>The device has a marking equipment (4) for applying color marking fluid (5) from a marking fluid reservoir (6) on a smooth or rough surface (1) e.g. wall, and a pneumatic valve (8) controlled by a mechanical grill unit. A nozzle (9) is provided with a nozzle axis (d), and the reservoir is a pen (11) with a pen axis and with a porous stylus (12), where the pen is insertable into a pen holder (10). The nozzle is connected with a gaseous fluid medium (13) e.g. pressurized air, over the valve, and the holder is arranged adjacent to the nozzle.</p> |
