Abstract

PURPOSE: To accurately detect the dust removing time without halting the device by forming an AC circuit by the dust collecting part and capacitor and detecting the dust removing time from the AC current of this AC circuit.
CONSTITUTION: The dust collecting part 4 provided with a ground plate and high voltage plate is connected to a dust collecting DC high voltage power source 6 via choke coil 5 in order to block AC current. Also, the dust collecting part 4 is grounded by way of a transformer 7, and the AC power source 8 of the specified frequency and specified voltage is connected to this transformer 7. Further, the decision circuit 11 having a current detector 10 on the AC circuit by the dust collecting part 4 and coupling capacitor 9 provides the decision output deciding the time when the detection current exceeds the specified value to be the time requiring dust removing in the dust collecting part. As a result of this, the need for interrupting the dust collecting operation for the detection of the dust removing time is eliminated.
