An illumination device for an indicating needle includes a plurality of light sources, an indicating needle, a guiding member, and a luminance control unit. The indicating needle includes a needle body and a needle base. The base has an entrance surface and a reflection surface. A luminance control unit controls luminance of the light sources in response to turning of the indicating needle such that the luminance is lowest when a light emitted perpendicularly from a center of an emitting surface of the light source is reflected off a reflection surface's region which a longitudinal central line of the needle body intersects with, and that the luminance gradually increases as the light emitted by the light source from the center of the emitting surface thereof is reflected off a region that is more distant from the region which the longitudinal central line of the needle body intersects with.

A head-up display device includes a housing; a display unit accommodated in the housing for emitting a projected image; a reflector for reflecting the projected image passing through an opening in the housing toward an eye range of a vehicle driver. The head-up display device further includes a movable member attached movably to the housing, and the display unit is fixed on the movable member. A position of the projected image is adjusted by only moving the movable member.

The pointer illuminator includes: an optically transparent pointer member having a reflecting surface for a pointer, which surface reflects, light incident on a predetermined surface of incidence and guides the light to a tip of the pointer; a light source arranged around a drive shaft of the pointer member; and an optically transparent light-guiding member, which guides light from the light source to the surface of incidence and includes a first light-guiding reflecting surface provided on a face of the light-guiding member, an angle which the face forms with a center axis of the light source becoming smaller as the face leaves the light source so that the first light-guiding reflecting surface reflects the light from the light source to convert the light into approximately parallel light rays, whereby the light-guiding member guides the parallel light rays to the surface of incidence.

A multi display device includes: a first display disposed at a predetermined position; a second display disposed 10B in front of the first display 10A and being movable from a first position where the second display overlaps with the first display to a second position where the second display does not overlap with the first display; and a transferring member for moving the second display. When the first display is mainly monitored, the second display is transferred to the second position, and when the second display is mainly monitored, the second display is transferred to the first position.

A speedometer for a vehicle includes a display part, formed into a circular shape and that includes a movable portion rotatable about a center thereof, the movable portion having an indication design, a pointer that rotates to indicate the indication design for displaying the running speed of the vehicle. During a normal driving, the pointer rotates to indicate a position on the indication design of the movable portion that corresponds to a current running speed of the vehicle while the movable portion is fixed. During a driving with an adaptive cruse control system, the movable portion rotates so that the pointer indicates a position on the indication design of the movable portion that corresponds to the current running speed of the vehicle while the pointer is fixed.

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.

An apparatus is used for diagnosing the temperature state of a catalyst converter. The catalyst converter includes a catalyst for cleaning an emission, and a conductive carrier for carrying the catalyst. The conductive carrier is energized for temperature rise of the catalyst, and the conductive carrier has a characteristic in which resistance drops with temperature increase. In the apparatus, a first obtaining unit obtains a first parameter having a first correlation with supply power to the conductive carrier for energization of the conductive carrier. A second obtaining unit obtains a second parameter having a second correlation with a temperature of the conductive carrier. A diagnosing unit diagnoses the temperature state of the conductive carrier based on a comparison between the first parameter and the second parameter.
