Abstract
A vehicle-mounted meter system includes: an inputting and outputting circuit for data measured to show a condition of the vehicle, a control circuit for controlling the system as a whole and for procession of the data, a meter main body, and a control unit detachably attached to the meter main body. The data inputting and outputting circuit is arranged on the meter main body, and the control circuit is arranged on the control unit. Preferably, the meter main body has a random bus structure corresponding to the data inputting and outputting circuit, and the bus structure has a buffer through which communication is allowed between the data inputting and outputting circuit and the control circuit.
