Claims

[Claims for Utility Model Registration] (1) A vehicle meter having a dial having a scale that emits light by backlighting, and a light source disposed behind the dial, the scale of the dial A light-transmitting opening is formed inside the dial, and a shutter that can be selectively switched between a light-transmitting state and a light-blocking state is connected between the dial and the light source so as to cover the opening of the dial. In preparation for this, the above shutters should be made translucent when the vehicle is in a warning state.
A vehicle meter characterized in that a warning state of the vehicle is indicated by lighting the inside of a scale portion of a dial plate. (2) The vehicle meter according to claim 1, wherein the shutter is a liquid crystal shutter. (3) Two polarizing plates, at least one of which is a composite polarizing plate, are provided between the dial and the light source at the opening of the dial, and the mutual polarization directions of the two polarizing plates are changed. 3. The vehicle meter according to claim 2, wherein the light emitting pattern of the opening is changed by changing the light emitting pattern of the opening. (4) Claim 1, wherein the shutter is two polarizing plates whose polarization directions are mutually changed.
Vehicle meter listed. (5) A composite polarizing plate is provided between the dial and the light source at the opening of the dial, and either one of the two polarizing plates constituting the shutter and the composite polarizing plate are provided. 5. The vehicle meter according to claim 4, wherein the light emitting pattern of the aperture is changed by changing mutual polarization directions of the apertures.
