The invention relates to a device including: a movable element (1) comprising teeth (11; 11 i , i, 11 i+1 , 11 i+2 ,11 i+3 , 11 i+4 ); a driving element (2) for engaging with the teeth (11; 11 i , 11 i+1 , 11 i+2 ,11 i+3 , 11 i+4 ) of the movable element (1) so as to set the movable element (1) in motion in a direction of movement; an actuator element (3) capable of generating an alternating movement so as to move the driving element (2) according to at least two phases, i.e. a driving phase, during which the driving element (2) is engaged with a tooth (11; 11 i , 11 i+1 , 11 i+2 ,11 i+3 , 11 i+4 ) of the movable element (1), and a return phase without driving, during which the driving element (2) is shifted with respect to the movable element (1); and a first indexing element (4), which includes a first indexing finger (41) to be positioned between two teeth (11; 11 i , 11 i+1 , 11 i+2 ,11 i+3 , 11 i+4 ) of the movable element (1), and which is connected to the actuator element (3) in order to move the driving element (2) and the first indexing finger (41) simultaneously.

The invention concerns a device comprising an element to be driven (10) and a driving element (250) designed to be urged into engagement with the element to be driven (10) and an actuating element (202) adapted to generate a reciprocating movement to move the driving element (250), the driving element (250) and the actuating element (202) being formed by etching in a semiconductor material block. The invention is characterized in that it is arranged such that: during a first alternation (a) of the movement generated by the actuating element (202), the driving element (250) is urged into engagement with the element to be driven (10) to pull the element to be driven (10), during a second alternation (b) in the opposite direction generated by the actuating element (202), the driving element (250) slides on the element to be driven (10), such that the element to be driven (10) is displaced in a step-by-step movement by the driving element (250).

The invention relates to a method for counting events occurring during a period T carried out by a mechanical counter comprising two toothed wheels with the same pitch, the occurrence of an event causing the rotation of each wheel by an angle corresponding to the pitch of the teeth thereof, said method comprising: a first step of counting or calculating, for each wheel at the end of T, the difference in the number of teeth between the initial and final position thereof, said step being at least partially carried out either by optical means, requiring the presence on each wheel of at least one marker, or by means for measuring the angular displacement of each wheel and associated calculation means; and a second step of calculating the number of occurred events N in accordance with the difference between the values counted or measured and in accordance with the number of teeth of the wheels.
