<p>The invention relates to a writing tool comprising a liquid ejecting head (41) and a processing unit (6) for actuating said ejecting head. In addition the inventive tool comprises measuring means (12) for measuring the distance between the ejecting head and a support and motion detecting means. The processing unit is adapted for controlling the liquid ejecting head (41) actuation when at least measuring means determines that the distance between the liquid ejecting head (41) and the support is less than a maximum predetermined value and the processing unit is also adapted for managing the ejecting head activation according to a motion detected by motion detecting means.</p> |
