CONSTITUTION:When an automobile is registered, the operator inputs an item code by operating a keyboard 4 in order to write the date of the registration into an RAM15. When the code is inputted, the writing programs prepared beforehand in an ROM11 are executed. When the writing programs are executed, the route of an automobile diagnosing device-input terminal 13-input interface 14-input interface 5-MPU2-RAM15 is opened, and the capacity of information is written thereon. In the case of writing other items such as information on legal inspection, etc., writing is carried out by the similar sequence. When read out programs are executed, the necessary information is fed automatically from the RAM15 to the automobile diagnosing device in the route of the RAM15-MPU2- output interface 16-output terminal 17-automobile diagnosing device. |
