Abstract: An instrument driver is provided in which a radical new representation can be used in presentation operation to improve marketability and design. The instrument driver includes an instrument 2 indicating vehicle information by turning of a pointer on a display plate and first and second illuminating means 2d and 2e for illuminating the instrument with different illumination colors. Control means 1 and 2a is included which causes the instrument 2 to perform presentation operation different from normal display operation in response to an input of a predetermined start signal and gradually changes at least brightness of the first illuminating means 2d and brightness of the second illuminating means 2e at different times as the presentation operation. The start signal is an input for turning on or an input for turning off a power source switch.

Abstract: A meter driving apparatus is provided in which the display luminance of a plurality of placed meters can be adjusted in synchronization to enhance the appearance of the whole additional meter system. The driving apparatus is for a plurality of meters 2 and 3. The meters include the first meter (digital meter) 2 including an optical sensor 2d for detecting the surrounding brightness and having an auto-light-adjustment function of obtaining light-adjustment data for adjusting the display luminance of the meter 2 in accordance with the detection result of the optical sensor 2d and the second meter (analog data) 3 having no optical sensor. The driving apparatus has a control unit 1 which transmits the light-adjustment data obtained by the first meter 2 to the second meter. The second meter 3 adjusts the display luminance thereof based on the light-adjustment data received from the control unit 1.

Abstract: A meter driving device 1 includes a meter (a combination meter) 6 including state display units (first and second analog display units and a digital display unit) 6b, 6c, and 6d that display vehicle states, control means (first control means and second control means) 4a and 6a for inputting state signals indicating the vehicle states, calculating vehicle state data on the basis of the state signals, and causing the state display units 6b, 6c, and 6d to operate on the basis of the vehicle state data, and storing means (a memory card) 4b for storing the vehicle state data and data other than the vehicle state data during a predetermined time in synchronization with each other.

Abstract: A display device includes a pointer 18 including an indicating part 18a, pointer driving unit 20 for rotating the pointer 18, and a display element 17 including an index part 23 indicated by the indicating part 18a. The display element 17 includes a pair of translucent substrates 26 and 27, stripe-shaped transparent electrode films 24 and 25 respectively formed on the translucent substrates 26 and 27, and light shielding parts 33 and 46 provided on at least one of the translucent substrates 26 and 27, and the index part 23 is made of an opening of the light shielding parts 33 and 46. The display element 17 includes a hole part 36 formed in a place corresponding to a rotation shaft of the pointer driving unit 20.

Abstract: A first indicator has a display board, a pointer to point the display board, a light source to subject the display board to transmitted illumination, and pointer driving means to drive the pointer. A housing stores the first indicator, a second indicator formed of a first light emitting type indicator, and a third indicator formed of a second light emitting type indicator. The viewer sees the second indicator reflected upon a semi-transmitting reflection board, the third indicator through the semi-transmitting refection board, and the first indicator not through the semi-transmitting reflection board.
