Abstract
A reset device (7) for the digit rollers (3) of a counter has a positioning spring (22) developed integrally on a shift drive bridge (9), the positioning spring being adapted to engage by means of a detent projection (21) into detent recesses (17-20) of the side surfaces (13-16) of a position setter (12). In this way, the position setter (12) passes in particularly reliable manner into each of its four possible positions.
