Claims

[Scope of utility model registration request]

A sensor unit that converts the rotational speed of a rotating body, such as the rotational speed of a vehicle or the rotational speed of an engine, which is proportional to the running speed of the vehicle, into a pulse signal proportional to this; It consists of a speedometer that displays the rotation speed on the speed display section, and a scale is set by selecting the speed range to be displayed in full scale on the speed display section. is provided with a plurality of sensing parts that are sensitive to the above-mentioned detection part along its rotation trajectory, and the number arranged on one rotation trajectory of the upper sensing part is displayed for each speed range on the full scale of the speed display section. A tachometer with an enlargement function, characterized in that a plurality of detection blocks each having a different number of sensitive parts are arranged in parallel, each set in an independent detection block unit.
