Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuity inspection method for inspecting defects such as disconnection and short circuit of a signal line, and a gaming machine to which the inspection method is applied.

[0002]

BACKGROUND OF THE INVENTION Generally,
The gaming machine has a control system for controlling the gaming operation. This control system generally includes a main control board (main control section) for controlling the overall operation of the gaming machine, and a plurality of sub-control boards (sub-control section) provided for each function of a plurality of electronic components installed in the gaming machine. ). As this sub-control board,
For example, in a pachinko machine, a payout control board that controls a payout operation of award balls, rental balls, and the like, a voice control board that controls the output of sound effects and the like, and a lamp that controls turning on and off an electric decoration member attached to a game machine A control board, a launch control board for controlling the launch of the pachinko ball, a display control board for controlling the symbol display of the symbol display device provided in the gaming machine, and the like are provided.

The main control board and each sub-control board are connected by signal lines, and various data signals and command signals can be transmitted from the main control board to each sub-control board. Also,
A control program is stored in the main control board in advance, and a command signal is transmitted to a predetermined sub-control board according to the control program. The sub control board controls the operation of each of the above electronic components by receiving the command signal.

[0004] For example, when a pachinko ball wins at each winning port arranged on the game board of the gaming machine, the main control board transmits a command signal indicating the number of award balls to be paid out to the payout control board. On the other hand, the payout control board pays out a designated number of balls according to the received command signal. here,
Pachinko balls actually paid out are monitored by both the main control board and the payout control board, and if there is a difference in the number of balls, an error is reported.

However, in the above-described prior art, the command signal output from the main control board may not match the command signal received by the sub-control board. The causes are as follows: 1. Disconnection of the printed pattern (connection) of each board, or failure of hardware such as failure of parts.

2. Unauthorized acts such as shorting pins between connectors or exchanging signal lines to forcibly change an electric signal level and input an illegal command signal.

[0007]

In order to solve such a problem, it is necessary to check the operation of the equipment as needed even after shipment.

For example, in Japanese Patent Application Laid-Open No. 08-266723, a main board for image quality test of an image display device installed in a game machine is detachably provided on an image display control board. A technique for performing an image quality test by transmitting a command image for an image quality test from the main board side to the image display control board side in a state where the board is connected and displaying a test image on an image display has been proposed. I have.

However, in the above-described conventional technology, data exchange from the main control board to the sub-control board (such as the payout control board or the image display control board) is permitted only in one direction (one direction from the main control board). However, there is a problem that it is not possible to confirm whether the command signal output from the main control board matches the command signal actually input to the sub-control board.

Is output through the harness 153
Each input terminal D _I 0 of the CPU 152A of the payout control board 152
~ D _I 7 and the control signal input C _I.

As shown in FIG. 10, the main control board 150
The harness 153 connecting the payout control board 152 and
Specifically, it is constituted by a flat cable connecting the connectors 150D and 152D. This harness 1
53 has flexibility, and is particularly effective for wiring in a narrow space, for example. However, since nine signal lines are arranged close to one line, adjacent signal lines may be short-circuited. ,
Moreover, since it is flexible, the possibility of disconnection is high.

In the first embodiment, a predetermined inspection signal can be transmitted from the main control board 150 in order to inspect for short-circuit or disconnection of these signal lines. The inspection signal includes 0110110 corresponding to the signal lines 153A to 153H of the harness 153.
1 (first check command), and 10101010
Two types of signals (second check command) are sequentially transmitted.

In the payout control board 152 on the receiving side, the above two types of inspection signals transmitted from the main control board 150 are recognized in advance, and the same inspection signal as the inspection signal transmitted from the main control board 150 is transmitted. If received, it can be determined that there is no disconnection or short circuit of the signal line.

If the signal line 153C is disconnected, the data transmitted from the main control board 150 is 1 when the second command data is transmitted, whereas
The payout control board 152, the input end of CPU152A D _I
The data to be received at 2 becomes 0 instead of 1. Thereby, the payout control board 152 can determine the disconnection of the signal line 153C.

It is assumed that the signal lines 153B and 15
In the case where 3C is short-circuited, for example, when the first command data is transmitted, the data transmitted from the main control board 150 is 0 on the signal line 153C, whereas the data on the payout control board 152 is , data to be received at the input terminal D _I 2 of CPU152A is 1 instead of 0.
That is, the first data in the next signal line 153B shorting is received at the input terminal D _I 2 of CPU152A via the signal line 153C. Thereby, the payout control board 1
At 52, it can be determined that the signal line 153C is short-circuited with the adjacent signal line 153B (or the signal line 153D).

Next, the operation of the first embodiment will be described.

First, when the power of the pachinko machine 110 is turned on, the CPU 150A of the main control board 150 shown in FIG.
Is executed. First, step 30
In the case of 0, power-on processing for each part of the control system is performed. As a result, power is supplied to the sub-control board 151 such as the pay-out control board 152, and the sub-control board 151 enters an operating state.

In the next step 302, the payout control board 1
A first check command is transmitted to the control command 52. The first check command transmitted here is composed of 8 bits, and differs between adjacent bits (01010110).
Send 1). In transmitting the check command, a control signal is transmitted together to synchronize transmission and reception of the check command (see FIG. 6A).

In the next step 304, the payout control board 1
A second check command is transmitted to the control unit 52. The second check command transmitted here is composed of 8 bits similarly to the above-described first check command, and differs between adjacent bits, but has a different pattern (10101010) from the first check command. ) Is transmitted, and this processing routine ends.

On the other hand, step 30 of the above processing routine
The processing routine shown in FIG. 5 is executed on the payout control board 152 that has been powered on by the process of 0.

When the CPU 152A receives the control signal at the control signal input terminal C _I, it receives the binary data transmitted to each of the input terminals D _I 0 to D _I 7.
It is determined whether or not the received data is a check command (a first check command or a second check command). If a negative determination is made in step 400,
Proceeding to step 406, pachinko ball payout preparation processing is performed, and this processing routine ends. Note that a control signal for transmitting the check command may be transmitted from the main control board 150 before transmitting the check command.

On the other hand, in the case of an affirmative determination in step 400, the flow advances to step 402 to determine whether or not the received data matches the first check command. If a positive determination is made in step 402, the process proceeds to step 404,
It is determined whether or not the received data matches the second check command. In the case of an affirmative determination in step 404, the process proceeds to step 406, in which pachinko ball payout preparation processing is performed, and this processing routine ends.

On the other hand, if the received data does not match the first check command, it can be determined that there is a disconnection or short circuit in the signal line.

[0050] For example, data transmitted from the main control board 150, whereas a 0 in the signal line 153C, the dispensing control board 152, rather than the data 0 to be received at the input terminal D _I 2 of CPU152A If it is 1, then
The next signal line 153B whose data being transmitted is 1
(Or the signal line 153D) can be determined to be short-circuited with the signal line 153C. Further, for example, the data transmitted from the main control board 150 is 1 on the signal line 153B, whereas the payout control board 152 has data 0 to be received at the input terminal D _I 1 of the CPU 152A instead of 1. In the case of, it can be determined that the signal line 153B is disconnected.

Accordingly, if the received data does not match the first check command, a negative determination is made in step 402, the process proceeds to step 408, where the payout of pachinko balls is stopped, and the present processing routine ends.

If the received data does not match the second check command, it can be determined that the signal line has a disconnection or short circuit.

For example, while the data transmitted from the main control board 150 is 0 on the signal line 153B, the data to be received at the input terminal D _I 1 of the CPU 152A is not 0 on the payout control board 152. If it is 1, then
The adjacent signal line 153A whose data being transmitted is 1
(Or the signal line 153C) can be determined to be short-circuited with the signal line 153B. Further, for example, the data transmitted from the main control board 150 is 1 on the signal line 153C, whereas the payout control board 152 has data 0 to be received at the input terminal D _I 2 of the CPU 152A instead of 1. In the case of, it can be determined that the signal line 153C is disconnected.

Therefore, if the received data does not match the second check command, a negative determination is made in step 404, and the flow advances to step 408 to perform pachinko ball payout stop processing and terminate the present processing routine. At this time,
Further, an error may be notified to the outside by a lamp, an LED, a sound, or the like.

In the first embodiment, as described above, the data confirmation processing in the payout control board 152 has been described. However, the voice control board 154, the lamp control board 156, and the launch Control board 15
8 and the display control board 160 can be similarly applied to the present invention.

As described above, in the first embodiment, if the data received when transmitting 1 as binary data is 0, it can be determined that the signal line is disconnected.
On the other hand, if the data received when 1 is transmitted as binary data is 1, it can be determined that the signal line is short-circuited with an adjacent signal line to which 1 is transmitted as binary data. Therefore, by comparing data between the transmission side and the reception side, disconnection and short circuit of the signal line can be inspected.

The transmission command is 2 bytes or 3 bytes. For example, the transmission command may be transmitted in combination with a check command (check data) and a prize ball instruction (prize ball number data) (see FIG. 6B). .

In the first embodiment, the check command may be transmitted and received in order for each bit. As a result, for example, the transmission path 153A and the transmission path 153C in the harness 153 due to fraud.
Can be determined even if the numbers are replaced. (Second Embodiment) Next, a second embodiment of the present invention will be described in detail.

In the second embodiment, the connector 150D of the main control board 150 shown in FIG.
In the 52 connectors 152D, the connection portions corresponding to the signal lines 153A to 153H of the harness 153 are:
As shown in FIGS. 7A and 7B, eight terminals T <b> 1 to T <b> 8 whose terminal arrangement is fixed in a hollow portion of the outer wall portion 502 having a rectangular cylindrical shape by a fixing member 504 in a 2 × 4 arrangement. Is used. The other configuration is the same as the configuration of the above-described first embodiment.

10, 11001100, 00110011). As a result, it is possible to inspect for a short circuit or disconnection between signal lines corresponding to adjacent terminals (for example, terminals T1, T2, T4, T5, and T6 for terminal T3).

Even when the number of rows and columns of the terminal arrangement of the connector is increased, disconnection and short-circuit of the signal line can be inspected in the same manner as in the second embodiment. (Third Embodiment) Next, a third embodiment of the present invention will be described in detail.

In the third embodiment, the main control board 150 and the payout control board 152 in the first embodiment are used.

They are connected to branch points P1 to P9 between B and the input buffer 152C, respectively. Thus, a binary signal input from each input terminal of the connector 152D can be input to each input terminal of the connector 152E via the branch points P1 to P9.

Further, nine independent signal lines 153A '
Each output terminal of the connector 152E and each input terminal of the connector 150F are connected to each other by the harness 153a having .about.153I '. Accordingly, the output terminals D _O 0 to D _O of CPU 150 'of the main control board 150a
