<p>PURPOSE:To thin an inverter device, minimize the number of part items, and simplify the assembling by integrating circuit parts consisting of one block onto a magnetic plate forming the core of a transformer. CONSTITUTION:A cold cathode-ray tube and circuit parts other than a load current limiting capacitor on the secondary side are collected into a small-sized thin block. Concretely, an inverter device has two magnetic plates 10, 40 which are mutually butted to form a closed magnetic path and two winding shafts 11, 12 formed on either one magnetic plate. For example, the primary winding 35 of a transformer is formed around a through-hole 31, and terminals 37, 38 are provided on both end parts, and these are positioned on a flexible printed board 30 and arranged around the shaft 12. A secondary winding 50 electromagnetically connected to the winding 35 is connected to a terminal 39 provided on the board 30, and a chalk coil 60 is connected to a winding shaft 13 adjacent to the winding shaft 11. Thus, circuit parts 90 such as transistor and capacitor are mounted on the conductor pattern of the board.</p> |
