Meter for automotive vehicle
First Claim
1. A meter for an automotive vehicle comprising:
- a back light illuminating with a predetermined color,a display portion comprising a first deflecting plate, a second deflecting plate, and a phase difference portion for providing a meter design having scales and letters, the display portion disposed in front of the back light and being changeable between a positive mode and a negative mode at a predetermined speed, anda reverse control device determining whether an engine of the vehicle is in an initial starting step or the vehicle is in a running state, the control device reversing the display portion at a speed in response to a result of the determination, wherein the reverse control device has a reverse operation control unit for controlling an intersection angle between a first deflecting axis of the first deflecting plate and a second deflecting axis of the second deflecting plate so as to at least partly transmit or block light emitted from the back light, the intersection angle being from 0°
to 90°

Abstract
The meter has a back light illuminating with a predetermined color, a display portion disposed in font of the back light and being changeable between a positive mode and a negative mode at a predetermined state, and a reverse control device determining whether an engine of a vehicle is in an initial starting step or the vehicle is in a running state. The control device reverses the display portion in response to a result of the determination. The control device changes the display portion from one of the positive and negative modes to the other at a lower speed when the control device determines that the vehicle engine is in an initial starting step than when the control device determines that the vehicle is in a running state. When the control device determines that the vehicle engine is in an initial starting step, the control device changes the display portion in one of the positive and negative modes from a neutral contrast state.
