That is, when the controller 2 is powered on without pressing the reset key 20 of the drip meter, the read control means 13 determines that the stored data of the type of the controller 2 is being read. When the controller 2 is turned on while the reset key 20 is pressed and the stored data is output to the display means 1, it is determined that the vehicle data is being read out, and the memory related to the vehicle data is stored. Since the data is read from the non-volatile memory 3 and output to the display means 1, the non-volatile memory 3 is stored in the non-volatile memory 3 while storing the type of the controller 2 while preventing an erroneous output of the data. It can also be used as a storage means for storing vehicle data.

Further, the non-volatile memory 3 may have a structure in which a function as a storage means for storing the traveling distance of the vehicle in a normal traveling state is added. In such a structure, the structure of the electric component is provided. Can be further simplified.

In the above embodiment, an example in which the present invention is applied to an electrical component including a combination meter has been described. However, in addition to the combination meter, a controller such as a vehicle audio device and a navigation device is built in, and The present invention can be applied to various electric components controlled by this controller and provided with a display means.
