Abstract
. Thereby, the reading of the intrinsic identification information affixed to the electronic part on the control circuit board in the circuit board case, and the confirmation of the sealed state of the circuit board case can be reliably effected, thus preventing dishonest acts, such as replacing the electronic part by a new one in the inspection step and allowing the new one to read a dishonest intrinsic identification information.
