An in-vehicle display apparatus includes: multiple switchable display elements for displaying one of display items in a display group that is assigned each switchable display element; an operation device for outputting an operation signal according to an operation of a user; a determination device for determining an operation mode of the operation of the user with respect to the operation device, according to the operation signal; and a display control device for independently controlling each switchable display element to execute a switching and displaying operation according to the operation mode. In the switching and displaying operation, the display control device controls one of switchable display elements to switch a current display item to another display item according to a predetermined switching order of display items every time the operation device outputs the operation signal.

In-vehicle display apparatus

A luminous pointer of a displaying instrument has a pointer body with a light emitting area that is divided into subsections with prisms. The subsections are illuminated at different timing. A light emitting circuit, including light emitting diodes (LEDs) for illuminating the light emitting area, and resistors and zener diodes for driving the LEDs, is arranged in a boss of the pointer body. With this configuration, an increase in weight of the pointer body, especially at a tip of the pointer body, is less likely to occur.

Displaying instrument and luminous pointer

An indicator for use in a vehicle instrument panel has a light conductive pointer illuminated by a light emitting diode or LED. In order to provide an increased illuminating surface of the pointer, a slit is formed on a cap to extend from the outer periphery of the cap to a portion above a center of rotation of the pointer driven by a driving shaft. A fixture is connected to the driving shaft and holds a light receiving portion of the pointer at the portion above the center of rotation and the LED in the optical alignment with the pointer at a portion off an axis of the center of rotation. A balancing weight is disposed at a portion opposite the LED with respect to the driving shaft in order to keep balance of the indicator.
