Abstract

PURPOSE:To detect the inserting/pulling out of a package automatically, and to prevent noise without any hands by providing a light emitting part and a light receiving part in positions corresponding to a through hole in a package when the package is completely inserted in a connector. CONSTITUTION:The through holes 30-32 are provided in the packages 20-22, and the light emitting part 10 and the light receiving part 40 that receives light from the part 10 in a position corresponding to the holes 30-32 when the packages 20-22 are completely inserted in the connector. Accordingly, if any one of the packages begins to be pulled out, the through hole of the package also moves, and the light is no longer received. Therefore, the pulling out of the package can be recognized, and the occurrence of noise can be prevented by automatically dropping the power supply voltage or by stopping the supply of clock.
