Abstract (en)
The device has a spring (5) to selectively exert a torque on a zero-resetting lever (2) for pressing hammers (6c, 6d) against respective zero-resetting cams (7, 8). Articulation units articulate the hammers with respect to the lever and have a pin (2d) engaged in a guide slot (6a). The slot is oriented such that, during zero-resetting, direction of perpendicular, dropped from an axis of the pin onto the slot, intersects a straight line joining axes (7a, 8a) of the cams at a point. A pin (2e) is engaged with a play in an opening (6b) to allow a limited rotation of the slot around the pin (2d).
