摘要： An automotive instrument includes a light transmission controller and a mode selecting switch. The controller controls light transmission of a light-controllable film according to a selected position of the mode selecting switch. The mode selecting switch has three positions: two manual mode positions and an automatic mode position. The manual mode positions are provided for adjusting the light transmission to a fixed level. The automatic mode position is provided for controlling the light transmission so that a dial plate maintains a predetermined level of visibility. The dial plate can be switched between different appearances. This switching can be performed during the vehicle is in operation based on the driver's preference.

摘要： A pointer of a meter such as a speedometer for use in an automobile is so structured that it is observed as if its illuminated length extends upon turning on a key switch and as if its illuminated length is shortened upon turning off the key switch, thereby giving an ornamental effect to the meter. A pointer cover gradually covering or exposing the illuminated pointer may be provided at a vicinity of a zero-scale position. The pointer may be progressively illuminated by plural light sources disposed behind a scale plate by tuning on the light sources one by one. The light sources such as light-emitting diodes may be embedded in the transparent pointer needle. Plural light sources covered by a bimetal cover may be disposed at a foot portion of the pointer needle, and the bimetal cover may be heated to gradually uncover the light sources thereby to progressively illuminate the pointer needle.

摘要： An indicating instrument for a vehicle has a display board and a light modulation member disposed to cover a surface of the display board. When a condition that an illumination intensity of the display board is lower than a threshold value has continued for a first time period, a light transmissivity of the light modulation member is controlled to a first level so that a driver can easily see the display board. When a condition that the illumination intensity of the display board is equal to or higher than the threshold value has continued for a second time period, the light transmissivity of the light modulation member is controlled to a second level that is lower than the first level to restrict entry of external light to the display board.

摘要： An indicating instrument for a vehicle has a display board, a light modulation member disposed to cover a surface of the display board. An illumination intensity of the display board is detected by a light detecting member and a control unit applies to a dc pulse voltage to the light modulation member, to thereby control a light transmissivity of the light modulation member according to the illumination intensity. When the illumination intensity is higher than a predetermined level, the voltage is applied in one direction so that the light modulation member changes from a colorless condition to a colored condition to restrict an external light from reflecting on the display board. When the illumination intensity is lower than a predetermined level, the voltage is applied in a reverse direction so that the light modulation member is transferred from the colored condition to the colorless condition to maintain the visibility of the display board.

摘要： A graduation board has an arc-shaped graduation portion and translucent graduations disposed along the graduation portion. A light emitting pointer is disposed on a front side of the graduation board and moves along the graduations. A plurality of LEDs that are disposed on a reverse side of the graduation board emits respective graduations. A control circuit controls an emission order of the LEDs according to the movement of the light emitting pointer when a key switch of the vehicle is turned on. As a result, the combination meter provides attractiveness and originality for the driver, when the key switch turns on.
