PURPOSE:To provide a heat protecting device in which an operation for mounting a component such as a detector, etc., to protect against an overheat is simplified and an area for mounting an overheat protecting detector and an entire height of the component are reduced. CONSTITUTION:An overheat detector 4 is mounted on a side opposite to that of a circuit board 17 in which heat generating elements 6, 7, 8 are mounted, and connected by a conductor 18 passing both sides to detect abnormal overheats of the elements 6, 7, 8. An overheat protecting circuit stops the operations of the elements 6, 7, 8 with the signal from the detector as a trigger, thereby protecting the elements 6, 7, 8 against the overheat. |
