  • Patent number: 9719814
    Abstract: A needle type gauge includes: a needle that includes a main rotating portion that rotates around a rotation shaft, and an indicator which points out an index part; and an actuator. The main rotating portion includes a light emitting portion that emits strip-shaped light. The light emitting portion is located at the actuator side relative to the indicator, and emits the strip-shaped light to a nearby area to the indicator and located, relative the indicator, at one side in a rotation direction of the indicator. The needle includes a shield which extends in a direction of the actuator from the indicator, extends along the indicator, and blocks, among the strip-shaped light, light directed from the one side in the rotation direction of the indicator to the other side therein.
    Type: Grant

  • Patent number: 4906919
    Abstract: In the moving magnet type meter of the present invention, the coil mounting portions of a bobbin body are projected outwards in a generally arched shape on the central side to form circular arc-like or inclined surfaces, whereby the bobbin body can be made strong against the external pressure induced by the mounting of coils thereon and can be prevented from being deformed. Further, the upper portion of a movable magnet is centrally formed with an upwardly projecting shaft support portion for supporting a pointer shaft, and a thrust bearing portion is formed in the lower surface of an upper bobbin body portion in an opposed relation to the upper end face of the said shaft support portion through a predetermined slight gap, whereby the pointer shaft can be formed in the shape of a straight rod without forming a reduced-diameter portion serving as a thrust bearing, so the fabrication of the pointer shaft is easy and it is possible to maintain the strength of the pointer shaft itself.
