Abstract
A device comprising an element to be driven and a driving element designed to be urged into engagement with the element to be driven and an actuating element adapted to generate a reciprocating movement to move the driving element, the driving element and the actuating element being formed by etching in a semiconductor material block, are provided. During a first alternation (a) of the movement generated by the actuating element, the driving element is urged into engagement with the element to be driven to pull the element to be driven. During a second alternation (b) in the opposite direction generated by the actuating element, the driving element slides on the element to be driven, such that the element to be driven is displaced in a step-by-step movement by the driving element.
