摘要：PURPOSE:To enable safe balls and out balls to be detected on the board

surface of a pin ball game machine by composing a signal transmitting line and a signal

receiving line, of transparent conductor patterns formed on a glass substrate, and

metallic patterns formed on the patterns, and by setting the return-shaped signal

receiving line connected electromagnetically to the return-shaped signal transmitting

line at a face-parallel position and in the crossed direction. CONSTITUTION:A signal

transmitting line 22 is composed of the transparent conductor patterns of an I.T.O. film

22a formed on the one-side surface of a glass base substrate 17b with evaporation, and

metallic patterns formed along the patterns on, and a signal receiving line 26 is also

formed on the other side surface of the glass base substrate 17b, in the same manner.

The return-shaped signal receiving line 26 connected electromagnetically to the return-

shaped signal transmitting line 22 at a faceparallel position and in the crossed direction is

set, and when current is permitted to flow to the signal transmitting line 22 and a

magnetic field is generated, then an electromotive force is generated on the signal

receiving line 26, and when conductors like pin balls B approach, then the current of the

signal transmitting line 22 is changed, and according to the change, the scale of the

electromotive force of the signal receiving line 26 is changed, and so the approach of the

conductors can be discriminated. Accordingly, by the sensor of the conductors, the

movement of safe balls and out balls can be followed on the board surface of a pin ball

game machine.
