The capacity of the bidirectional RAM 76 is, for example, 2048 bytes.

Next, the analog multiplexer 52 of the receiving circuit 50 switches the signal from each receiving line 26 (see FIG. 21).
32 according to 32 reception lines 26 (see step 95)
The above steps are repeated once (see step 96 in FIG. 21). After repeating 32 times, the analog multiplexer 44 of the transmission circuit 40 switches the transmission line 22 (see step 97 in FIG. 21), and repeats the signal processing again.

Thus, the reception line 26 in which the reception signal has changed
, And the transmission lines 22, 22 ... Transmitted at that time can be detected by scanning, and the position of the pachinko ball on the matrix sensor 20 can be grasped as coordinates from the intersecting position. The number of detection units 20a is 32 for the transmission line 22.
Since there are 1024 rows and 32 reception lines 26 in total,
It can be detected even if the pachinko ball passes through any of the safe holes 14a and the out holes 15 on the board surface 11.

The bidirectional RAM 76 determines the position of the pachinko ball in the matrix sensor 20 from the intersection position of the reception line 26 in which the reception signal has changed and the transmission line 22 transmitted at that time, based on the signal from the reception circuit 50. It is stored as detection data of the detection unit 20a by each transmission line 22 and each reception line 26.

The CPU unit 30 reads the detection data relating to the position of the pachinko ball recorded in the bidirectional RAM 76 by a read start signal as necessary, performs arithmetic processing, and the detection data is stored in the card 63. The pachinko balls are monitored in association with the monitoring data.

The CPU unit 30 repeats this process. The matrix sensor 20 can follow the movement of a pachinko ball on the board surface 11 of the pachinko game machine 10, such as the state of entering the pachinko ball, as a change in coordinates. Pachinko game machine 10
Then, by monitoring the progress of the game by the matrix sensor 20 and knowing the conditions of hitting balls, out balls, and safe balls of the winning prize device device 14b, it is possible to perform stop management, check abnormalities due to fraud, and adjust nails. It can be used as data.

The inner glass body 17 is formed by quadruple lamination of an inner protective glass plate 17a, a receiving side glass base substrate 17b, a transmitting side glass base substrate 17c, and an outer side glass plate 17d, and a receiving side glass base substrate. 17b
Alternatively, the transmission-side glass base substrate 17c may be formed of one sheet to form a triple-layered structure.

According to the pachinko ball detection device and the pachinko game machine of the present invention, the transmission line and the reception line are
Since it is composed of the folded portion, the transmission terminal, the lead portion, and the wire, the matrix sensor can be made thin so as not to be conspicuous by the wire. Further, since it is easy to make the wire uniform in thickness, it is possible to improve the detection accuracy and reduce the manufacturing cost. Further, since the transmission terminal is formed on the transmission side routing board along the adjacent side of the side closest to the opposite side of the side, as compared with the case where the transmission terminal is provided closer to the center, Since the length of one side of the circuit board can be shortened and the area of the transmitting circuit board can be reduced, the material cost of the transmitting circuit board can be reduced.

In the receiving side routing board, when each routing part is connected to each receiving terminal through the through hole, the transmitting circuit and the receiving circuit can be connected to the transmitting terminal and the receiving terminal from the same side. , Easy to connect.

When the transmitter connector and the receiver connector are mounted by surface mounting, the transmitter connector and the receiver connector can be easily mounted.

In the pachinko game machine, the pachinko ball detection device can follow the movement of the pachinko ball on the board as a change in coordinates.
