PURPOSE:To have the engagement between a follower gear coupled to the revolving shaft of a display mechanism and a single driving gear and rotate the display mechanism in the forward direction regardless of the revolving shaft revolving in proportion to electric energy by providing the 1st and 2nd reverse gears and the 1st and 2nd ratchet mechanisms to a main revolving shaft. CONSTITUTION:The revolving shaft 5 and a change gear mesh mechanism 4 are couplled to a worm mechanism 6 connected to the revolving shaft 1 which supports a rotor. The 1st and 2nd gears 7 and 8 are held to the shaft 3 so that they can be freely revolve forward and backward. The 1st and 2nd ratchet mechanisms 9 and 10 are provided to the gears 7 and 8 respectively, and furthermore the 1st and 2nd reverse gears 16 and 17 provided to the revolving shaft 14 are connected to the gears 7 and 8 respectively. An accumulation display mechanism 11 is connected to the shaft 14 via a driving gear 15. Then the mechanism 11 is revolved forward regardless of the revolving direction proportional to the electric energy applied to the revolving shaft. In such a way, the assembly is simplified for the titled measuring device together with the improvement of display accuracy. |
