When the reader- writers 12a and 12b receive the identification signal transmitted from the non- contact type ID card 11 continuously, whether the different identification information of the received identification information exceeds the allowable number of people for dust removal of the air shower device 2 stored in a memory 13b is checked. If it exceeds, a warning is given on a display part 10. Also, a warning sound is given by an alarm part 16.;COPYRIGHT: (C)2002,JPO
