<p>PROBLEM TO BE SOLVED: To obtain a small fly-back transformer electrically connected without bending work and overhead wiring of lead wires of electric components, thereby improving the workability. SOLUTION: At least, using a plurality of circuit boards and utilizing patterns formed on the circuit bards, a diode, a capacitor and an anode lead are connected to form a high voltage rectifier on one circuit board, and a diode and a capacitor are connected similarly on the other circuit board to form a low voltage rectifier. A transformer is disposed and sandwiched between the circuit boards constituting the high and low voltage rectifiers, and the respective circuit boards are electrically connected through electric components such as voltage divider resistors, etc., to form a small fly-back transformer.</p> |
