ABSTRACT:
A mechanism for converting a weight into a frequency by means of a tuning fork vibrator having a pair of elongated plate-like vibrating strips extending in parallel with each other, a lever unit with a power pivot, fulcrum pivot and a load pivot, and a base portion, both ends of the tuning fork vibrator being coupled with the power pivot of the lever unit and the base portion, respectively by means of thin plate-like members. The weight to be converted is applied to the load pivot of the lever unit and is transferred to the tuning fork vibrator by means of the lever unit. All the parts of the mechanism are formed integrally from a single plate.
