摘要
The subject matter of this invention is an operating mechanism for a digital meter for pétanque and other ball games, with a manual system for measuring distances by means of extendable rods (8) connected to a rotational base (7) and with a digital system with facing infrared transmitters (16) and receivers (17) which interfere with the passage of perforated elements, either a wheel in a first embodiment or the measuring tape (14) itself in a second embodiment. In this second case, the transmitters (16) and receivers (17) are accommodated in an assembly comprising a box (30) and a cover which ensure the equilibrium and immobility thereof. The measuring tape (14) rolled up on a reel (15) has a brake (10) which can be displaced with an adjustment spring (27) and an extension stop. The digital elements are supported on a base plate or programmable printed circuit (11).
