<p>PROBLEM TO BE SOLVED: To provide an electric apparatus the heating element of which can be prevented preliminarily from exceeding a prescribed temperature. SOLUTION: This electric apparatus is provided with a heating element 1, a blower 2 for sending air to the element 1, a current transformer 9 for detecting an ampere of the blower 2, a relay 7 for switching over the power- supplied state to the element 1 and a microcomputer 3 for controlling a transistor 6 and another transistor 10 so that the power supplied to the element 1 is broken by the relay 7 when it is decided according to the ampere detected by the transformer 9 that the blower 2 or a photo-coupler 5 is abnormal.</p> |
