A CPU subtracts a specified value from the maximum value among the measurement values, and stores three times for a detection frequency more than a difference in a RAM. The CPU further multiplies the stored value "three times" at detection time intervals, a moving speed of the sucking nozzle, and 10<SP>-6</SP>, and stores the result in the RAM as the nozzle diameter of the sucking nozzle. The CPU determines whether a nozzle diameter is within a range of a1-a2 of the nozzle diameter of the type A that is stored in the RAM or not.  <P>COPYRIGHT: (C)2009,JPO&INPIT
