The invention concerns a fountain pen comprising a body (100) having an opening (120) wherein is housed a lead (190) whereof one first end (191) can emerge outside the body (100) through said opening (120), the lead (180) being rigid and free in translation along a longitudinal axis (X-X) of the body, and the fountain pen comprising a device (11, 170) sensitive to a force, which is arranged between a stop element (12) integral with the fountain pen body (100) and the second end (192) of the lead (190) and which co-operates with a second end of the lead (192) to deliver an output electric signal (S) whereof the continuous values represent the intensity of a force (RFx) exerted on the first end of the lead, the fountain pen further comprising prestressing means (14) enabling the second end (192) of the lead to exert a non-null prestressing force on the sensing element (11) when the force exerted on the first end of the lead is null. |
