PURPOSE:To make small the size of receiver, by forming the laminated transformer through the print of conductors and magnetic substances of a plurality on the surface of magnetic substance board with equal distance, forming the antenna function on one side of the board and the circuit pattern on another side, and constituting the coil in thin plate. CONSTITUTION:The conductors 20 of equal distance and having right sided slope are printed on the surface of the magnetic substance board 1. The conductors 20 are divided into the primary group P and the secondary group C every other place to the group P, and they start from PS, CS down left and end PF, CF up right. Next, the magnetic substance 21 having the window 22 is printed and insulation is given the same as the board 1. Further, the conductors 23 of left slope connecting the conductor P to the adjacent conductor P are printed and the magnetic substance 31 similar to the magnetic substance 21 is printed. Thus, the laminated transformer is formed, and the antenna function is given to one side of the board and the circuit pattern is given on another side of the board 1, allowing to constitute the coil in thin plate and to make small the receiver in size. |
