<P>PROBLEM TO BE SOLVED: To precisely remove input noise components in the amplitude control of an oscillating type component supply apparatus (part feeder) to enhance the stability of control. <P>SOLUTION: A pass band selector 20 for outputting a switching signal of a pass frequency band to a filter 15 into which an output signal of an oscillating sensor 12 is inputted is provided in a control circuit 11. When an operator selects one of a plurality of drive voltage patterns in a setting device 17 in response to a running condition of the part feeder, the switching signal based on the selected drive voltage pattern is outputted from the pass band selector 20 to the filter 15, and one of the plurality of pass frequency bands in the filter 15 is selected by the switching signal, thereby appropriately setting the pass frequency band in a narrow width. Thus, the input noise components are more precisely removed than conventionally, and the stable control can be performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
