In the pachinko machine of the present embodiment, the special symbol control board 130 and the payout control board 190 are controlled from the main control board by a 2-byte control command. In addition, complicated control can be performed, and the processing load on the main control board can be reduced. For this reason, a high-level game can be realized by the main control board, and the complicated control can be completed in a short time by the special symbol control board 130 and the payout control board 190.

Here, in this embodiment, as shown in FIGS. 8, 9 and 10, the upper 4 bits of the first 1 byte of the control command sent from the main control board 100 to the special symbol control board 130 are "E". (1110) as an identifier. Further, as shown in FIG.
The upper 4 bits of a 1-byte control command sent from 0 to the voice control board 180 are created using “5”, “7”, and “A”. As shown in FIG. 12, the upper 4 bits of the first byte of the control command sent from the main control board 100 to the payout control board 190 are created using “3” and “4”. As shown in FIGS. 13 and 14, the upper four bits of a 1-byte control command sent from the main control board 100 to the lamp control board 150 are “6”, “8” (not shown), and “9” (not shown). (Not shown) and "F".

In the pachinko machine of this embodiment, since the identifier of each sub-control board is included in the control command, the connector is connected to a different sub-control board by unauthorized operation, for example, the cable to the voice control board 180 is connected. Even when connected to the payout control board 190, the payout control board 19
0 does not work.

In the present embodiment, the identifier is included in the control command. Alternatively, at least one bit of the signal of the control command applied in parallel to the signal line can be made different for each sub-control board. . For example, a specific bit of a signal to the payout control board 190 is set to 1,
All other sub-control boards are set to 0, or 2 bits of the special symbol control board 130 are set to 00, 2 bits of the lamp control board 150 are set to 01, and the voice control board 180 is set to 0.
1, the payout control board 190 is 11. Thus, even if a connector to a different sub-control board is connected to the payout control board 190 due to an illegal operation, illegal payout of award balls can be prevented.

Next, the processing by the payout control board 190 will be described with reference to the flowchart of FIG.
Here, from the main control board 100, a 1-byte command and a transfer signal of 31 hexadecimal signals (H) and a 1-byte command of a hexadecimal signal (H) of CF shown in FIG. The following describes an example in which the transfer signal is transmitted. First, the CPU of the payout control board 190 determines whether the upper 4 bits in the first 1-byte command are the identifier “3” (0011) indicating the payout control board 190 (S12). Here, when the identifier "3" is not included (S12: No), a connector for another sub-control board was erroneously inserted at the manufacturing stage, or another sub-controller trying to perform an improper operation after manufacturing. Since either the connector for the board has been inserted, the process ends.

On the other hand, when the identifier is "3" (0011) (S12: Yes), a process of adding the first command and the second command is performed (S14). Here, the first 31 (H) command (001100)
01) and CF (H) command (1100111)
1) is added to obtain 0. Thereafter, it is determined whether the operation result is 0 (S16). Here, when the calculation result is 0 (S16: Yes), since an appropriate signal has been sent from the main control board 100, the above-described ball sending motor 2
The control signal is sent to 76 to pay out the prize balls (one payout here) (S18). On the other hand, when the calculation result is not 0 (S16: No), the payout control board 190
Since there is a high probability that an illegal act has been performed, the process ends.

The main control board 100 monitors whether or not the prize ball is properly paid out in response to the payout control command sent by itself, based on the detection signal from the prize ball unit 272 shown in FIG. . Here, despite the transmission of the control command, as described above,
When the prize balls are not paid out, an error display is displayed on the special symbol display 34, and an error signal is sent to the centralized control computer on the hall side via the game frame information terminal board 280. Send out.

In the pachinko machine of the present embodiment, the payout control board 190 performs an arithmetic operation on the first byte command and the second byte command of the two-byte control command from the main control board 100, and controls the operation based on the operation result. In order to detect a command abnormality, for example, it is possible to detect that an illegal act of replacing one of the signal lines D0 to D7 of the cable C to the payout control board 190 has been performed.

In the present embodiment, since the second byte command is a complement of the first byte command, the second byte command can be easily generated on the main control board side. In this embodiment, the command of the first byte and the command of the second byte are subjected to arithmetic processing, and it is determined that the command is appropriate when the arithmetic result becomes 0. However, it is needless to say that various check methods can be adopted. No.

In this embodiment, only the special symbol control board 130 and the payout control board 190 are controlled by a 2-byte control command. However, the voice control board 180 and the lamp control board 150 are controlled by a 2-byte control command. It is also possible. Thereby, the voice control board 180
In addition, complicated processing can be quickly performed by the lamp control board 150, and the burden on the main control board 100 can be reduced.
