Claims

[Scope of Claim for Utility Model Registration] A pointer device for an instrument in which a pointer attached to the pointer shaft is rotated using a pointer shaft of an internal device as a rotation axis, and the valve is installed in an elongated hollow rod-shaped valve. a pointer consisting of a cold cathode tube in which two electrodes are arranged parallel to each other along the longitudinal direction of the bulb and the terminals of the electrodes are drawn out from the end of the bulb; a pointer holding member that holds a conductive member connected to the terminal of the cold cathode tube so as to intersect with the pointer shaft, and a pointer holding member that holds a conductive member connected to the terminal of the cold cathode tube around the pointer shaft; A pulse voltage of a predetermined frequency is applied to the electrodes of the cold cathode tube through the current conducting means to intermittently generate a planar glow discharge between the electrodes. An instrument pointer device characterized by a cathode tube that emits light.
