By the way, when the serial method is adopted for the transmission of the control signal from the control board to the motor driver, the parallel method is used when the program being executed is paused (break) in the debugging process of the program at the development stage. Since the processing load is different, there is a problem that it is difficult to turn off the motor output even if a macro instruction of ICE (in-circuit emulator) at the time of the break is used. Therefore, as a countermeasure, a signal line for transmitting a predetermined parallel signal (motor stop signal) is provided between the control board and the motor driver, and the parallel signal is changed from L level to H level at the time of program break. Thus, it is considered to add a function of invalidating a control signal (excitation data) for driving the motor in the motor driver and turning off the output of the motor. However, this is a function that is necessary only at the development stage (program debugging work), and is an unnecessary function when the gaming machine is installed and operating in the amusement store, but this is left as it is. In addition, there is a problem that the output of the motor during normal operation is suddenly turned off when noise caused by static electricity generated in the gaming machine is applied to the parallel signal input terminal of the motor driver.

The present invention has been made in view of such problems, and while ensuring the function of stopping the output of the drive source accurately at the development stage, the drive source is erroneously caused by the function during product operation. It is an object of the present invention to provide a gaming machine that can prevent operation.

Drive source stop means for forcibly stopping driving of the drive source based on a stop control signal from the game control means,
Mode switching means for selectively switching between a valid mode for validating the stop control signal and an invalid mode for invalidating the stop control signal based on a mode control signal from the game control means, and is the valid mode If the stop control signal is received, the drive of the drive source based on the drive control signal is forcibly stopped, and if the stop mode is the invalid mode, whether the stop control signal is received or not. Regardless, the drive source is driven based on the drive control signal.

According to the gaming machine according to the present invention, it is possible to ensure a function of accurately stopping the output of the drive source at the development stage, but when the product is in operation, the function is a cause of malfunction, and the drive source is erroneously affected by noise or the like. It can be prevented in advance.

This means a command for controlling all the motor drivers 500 at once.

“Valid / invalid designation” is information for identifying that this command is a motor stop signal valid / invalid command. In other words, it is information for distinguishing from the excitation output command described above.

“Output stop valid / invalid data” is information for identifying whether this command is a motor stop signal valid command or a motor stop signal invalid command, that is, a motor stop signal is valid (output stop valid mode) or This is information for setting the motor stop signal to invalid (output stop invalid mode).

Next, the sensor input command includes “sensor input data”. "Sensor input data"
Is information indicating detection information input from each of the detection sensors S1 and S2. Based on this detection information, on the production control board 200 side, the movable accessory 24 is present in (a) the initial position, (b)
It is possible to detect whether the state exists at the maximum movable position or (c) exists at the intermediate position (does not exist at the initial position and the maximum movable position).

Next, the circuit configuration of the motor driver 500 will be described with reference to FIG. Hereinafter, among the plurality of motor drivers 500 (1), 500 (2),..., The motor driver 50
A description will be given on behalf of 0 (1).

As shown in FIG. 7, the motor driver 500 has a DOUT terminal, a CLK signal as an input terminal.
Terminals, EN terminals, STOP terminals, INA0 to A1 terminals, INB0 to B1 terminals, and OUTA1 to A4 terminals, OUTB1 to B4 terminals, and DIN terminals as output terminals.

The DOUT terminal is connected to the data line DOUT and receives, for example, command data having a 16-bit length. The CLK terminal is connected to the clock line CLK, and receives a clock signal for identifying unit data (data for one bit) included in the command data. The EN terminal is connected to the enable line EN and receives an enable signal for determining the start and end of command data communication. The OUTA1 to A4 terminals are connected to the respective excitation coils of the motor MA, and the OUTB1 to B4 terminals are connected to the respective excitation coils of the motor MB. The INA0 and A1 terminals are connected to the detection sensors S1A and S2A, and the INB0 and B1 terminals are connected to the detection sensors S1B and S2B.

Here, at the development stage, as shown in FIG. 4, the STOP terminal is connected to the connection line STOP, and a motor stop signal for stopping the motor M is input from the effect control board 200.
This is because, in the debugging operation of the program at the development stage, when the program being executed is temporarily stopped (break), a motor stop signal is input from the effect control board 200 to the STOP terminal, so that the motor M at the break point is input. This is to stop the system accurately. on the other hand,
When the product is operated in the amusement store, as shown in FIG. 5, the STOP terminal is short-circuited to the ground, and the motor stop signal from the effect control board 200 is not input to the STOP terminal.
However, there is a possibility that a motor stop signal is input to the STOP terminal due to noise caused by static electricity or the like generated in the gaming machine on the STOP terminal, and as a result, the motor M that is operating normally. Will suddenly stop (malfunction). Therefore, in the present embodiment, the motor stop signal (hereinafter, including both the “motor stop signal from the effect control board” and the “motor stop signal due to noise”) input to the STOP terminal is switched between valid and invalid, While the function of stopping the motor M accurately can be secured at the time of a break in the development stage, the function is configured to prevent the function from causing a problem when the product is in operation (details will be described later).

As shown in FIG. 7, the motor driver 500 includes a communication circuit 501, a storage circuit 502, a comparison circuit 503, an output control circuit 504, an output circuit 505, and an input circuit 506.

The communication circuit 501 inputs command data from the DOUT terminal at the rising timing of the clock signal input from the CLK terminal, and takes this as serial data. At this time, the communication circuit 501 validates the command data when the “IC address” of the command data matches its own unique address, and treats the command data as invalid when it does not match the own unique address. When the own unique address is designated, the motor MA or MB designated by the “channel” of the command data is set as the control target.
The communication circuit 501 receives an enable signal (L level: enable, H level: disable) from the effect control board 200, and starts communication when the enable signal changes from H level to L level. When the enable signal changes from L level to H level, the end of communication is determined.

The memory circuit 502 includes a shift register, a latch register, and the like, for example, and acquires and holds the serial data captured by the communication circuit 501. This serial data is
While the predetermined load signal is input from the effect control board 200 to the communication circuit 501, it is held in the storage circuit 502, while “excitation data” is input to the output control circuit 504 when the load signal is input. Then, “output stop valid / invalid data” is transferred to the comparison circuit 503. The input / output timing of the load signal includes, for example, the timing after transmitting the excitation output command to all the motor drivers 500, the timing after transmitting the motor stop signal valid / invalid command to all the motor drivers 500, and the like. is there. In this way, the synchronization control of all the motors M can be achieved by sending the load command after the command transmission to all the motor drivers 500. Note that the storage circuit 502 does not input until the next load signal is input.
The serial data is held and data output to the comparison circuit 503 and the output control circuit 504 is maintained. When the next load signal is input, the serial data held so far is cleared, and the serial data newly acquired from the communication circuit 501 is acquired and held.

The comparison circuit 503 analyzes the “output stop valid / invalid data” transferred from the storage circuit 502 and compares whether the input command is a motor stop signal valid command or a motor stop signal invalid command. If the comparison result matches the motor stop signal invalid command, the comparison circuit 503 outputs an output stop invalid signal (L level) to the output control circuit 504. On the other hand, the comparison circuit 503 outputs an output stop valid signal (H level) to the output control circuit 504 when the comparison result matches the motor stop signal valid command. When there is no serial data (before receiving the first motor stop signal valid / invalid command), the comparison circuit 503 outputs an output stop invalid signal (L level) to the output control circuit 504.

In response to the output stop valid / invalid signal from the comparison circuit 503, the output control circuit 504 switches to the output stop valid mode for validating the motor stop signal or the output stop invalid mode for invalidating the motor stop signal. Whether to transfer excitation data to the output circuit 505 is controlled based on the input state (L / H level) of the motor stop signal. That is, when the output stop invalid signal (L level) is input from the comparison circuit 503, the output control circuit 504 switches to the output stop invalid mode in which the motor stop signal input from the STOP terminal is invalidated, and the motor stop signal The excitation data input from the comparison circuit 503 is transferred to the output circuit 505 regardless of whether L is at the L level or the H level. On the other hand, when the output stop invalid signal (H level) is input from the comparison circuit 503, the output control circuit 504 switches to the output stop valid mode that validates the motor stop signal input from the STOP terminal, and the motor stop signal If H is H level, the excitation data input from the storage circuit 503 is blocked from being transferred to the output circuit 505.

As shown in FIG. 8, the output control circuit 504 includes, for example, a NAND circuit 5041 and an AN circuit.
A combination with the D circuit 5042 is possible. The same number of combinational circuits as the output terminals (eight in this example) are provided. The NAND circuit 5041 receives the output stop valid / invalid signal from the comparison circuit 503 and the motor stop signal from the STOP terminal. N
As shown in the function table in FIG. 8, the AND circuit 5041 validates the motor stop signal (H level) when the output stop valid signal (H level) is input, and sends the signal to the AND circuit 5042.
Output level (output stop enable mode). On the other hand, when an output stop invalid signal (L level) is input, the motor stop signal (H level) is invalidated and an L level is output to the AND circuit 5042 (output stop invalid mode). Next, the AND circuit 5042 includes a NAND circuit 5.
The output signal (L / H level signal) from 041 and the excitation data (data signal for 1 bit of the excitation data) from the storage circuit 503 are input. The AND circuit 5042 is shown in FIG.
As shown in the middle function table, when the output signal from the NAND circuit 5041 is at the H level, that is, in the output stop invalid mode, the excitation data “0” or “1” is transferred as it is. On the other hand, when the output signal from the NAND circuit 5041 is at the L level, that is, in the output stop valid mode, the excitation data is cut off and the L level (“0”) is output. The circuit configuration shown in FIG. 8 is an example, and other circuit configurations may be adopted as a matter of course.

The output circuit 505 includes a plurality of transistors internally connected in Darlington (8 in this example).
Each transistor is provided with each output terminal (OUTA1 to AA).
4 terminals, OUTB1 to B4 terminals) are connected in a 1: 1 relationship. The transistor is not shown in the figure because of its well-known configuration, but the output control circuit is connected to the gate, the source is grounded, and one end of each exciting coil of the motor is connected to the drain. The other end of each excitation coil of the motor M is connected to a power source (for example, 16V). An excitation signal (excitation data) from the output control circuit 504 is input to the gate of the transistor of the output circuit 505. While an excitation signal (H level) is input to the gate, that is, while a voltage exceeding a threshold value is applied to the gate, a current flows from the drain to the source. As a result, the output terminals (OUTA1 to OUTA1) A current is supplied to the excitation coil of the motor M connected to the A4 terminal (OUTB1 to B4 terminal) via a transistor, and the motor M is rotationally driven.

The input circuit 506 transfers detection information (sensor input data) from the sensors S1 and S2 to the storage circuit 502. The memory circuit 502 holds the sensor input data transferred from the input circuit 506. The communication circuit 501 transmits the sensor input data (sensor input command) held in the storage circuit 502 to the effect control board 200 according to the transmission format in synchronization with the reception of the excitation output command. That is, the communication circuit 501 can identify the sensors S1 and S2 corresponding to the motor M to be controlled by receiving the device ID, IC address, and channel of the excitation output command, and is held in the storage circuit 502. The sensor S1
, S2 sensor input data is transmitted to the effect control board 200 at the falling timing of the clock signal.

[Action]
Next, in order to facilitate understanding of the present embodiment, the characteristic operation of the pachinko gaming machine PM will be described. FIG. 9 is a timing chart showing a process flow when the motor stop signal is validated, and FIG. 10 is a timing chart showing a process flow when the motor stop signal is invalidated.

First, with reference to FIG. 9, for example, processing when the motor stop signal is validated when debugging a program in the development stage will be described. As shown in FIG. 4, in the development stage, a connection line (parallel line) ST is connected between the effect control board 200 and the motor driver 500.
Connected by OP, a motor stop signal (L / H level) can be transmitted from the effect control board 200 to the motor driver 500.

First, during the operation of the motor M, at the timing T101 in the drawing, the effect control board 200 is displayed.
A motor stop signal invalid command is transmitted from the motor driver 500 to the motor driver 500. Thereby, an output stop invalid mode for invalidating the motor stop signal is set at timing T102 in the figure. At this time, the motor stop signal output from the effect control board 200 is set to L level (inactive). Next, at timing T103 in the figure, an excitation output command is transmitted from the effect control board 200 to the motor driver 500, and the output of the motor M is continued based on the excitation data included in this excitation output command (timing in the figure). T104).

Subsequently, at timing T105 in the figure, the motor driver 500 is transmitted from the effect control board 200.
A motor stop signal valid command is sent to. Thereby, the output stop valid mode for validating the motor stop signal is set at the timing T106 in the figure. Next, at timing T107 in the figure, an excitation output command is transmitted from the effect control board 200 to the motor driver 500, and the output of the motor M is continued based on the excitation data included in this excitation output command (timing in the figure). T108).

When the execution of the program is temporarily stopped (break) at the timing T109 in the figure, a motor stop signal (H level) is output from the effect control board 200 at the break point by, for example, the function of the ICE (in-circuit emulator). Send. At this time, since the output stop valid mode has already been entered, when a motor stop signal (H level) is input from the STOP terminal, the motor driver 500 outputs excitation data from the output control circuit 504 to the output circuit 505. The transistor of the output circuit 505 is turned off. Accordingly, no voltage is supplied to each excitation coil of the motor M, and as a result, the output of the motor M is turned off at the timing T110 in the drawing. As described above, in the debugging operation of the program, the output of the motor M can be stopped accurately at the breakpoint, and the debugging operation can be performed efficiently.

Next, with reference to FIG. 10, for example, processing when the motor stop signal is invalidated when the product is moving in an amusement store will be described. As shown in FIG. 5, when the product is operated at the amusement store, there is no need to use a motor stop signal. Therefore, the STOP terminal of the motor driver 500 is short-circuited to the ground. The motor stop signal (L / H level) cannot be transmitted to 500.

First, with reference to FIG. 9, for example, processing when the motor stop signal is validated when debugging a program in the development stage will be described. As described above, in the development stage, the effect control board 200 and the motor driver 500 are connected by the connection line STOP, and the motor stop signal (L / H) is sent from the effect control board 200 to the motor driver 500. Level) can be transmitted.

First, during the operation of the motor M, at the timing T201 in the drawing, the effect control board 200 is displayed.
A motor stop signal invalid command is transmitted from the motor driver 500 to the motor driver 500. Thereby, the output stop invalid mode for invalidating the motor stop signal is set at the timing T202 in the figure. At this time, the motor stop signal output from the effect control board 200 is set to L level (inactive). Next, at timing T203 in the figure, an excitation output command is transmitted from the effect control board 200 to the motor driver 500, and the output of the motor M is continued based on the excitation data included in this excitation output command (timing in the figure). T204).

Subsequently, at the timing T205 in the drawing, the motor driver 500 is transmitted from the effect control board 200.
The motor stop signal invalid command is sent again. As a result, the timing T20 in FIG.
In step 6, an output stop invalid mode for invalidating the motor stop signal is set. Next, at a timing T207 in the figure, an excitation output command is transmitted from the effect control board 200 to the motor driver 500, and the motor M is based on the excitation data included in this excitation output command.
Is continued (timing T208 in the figure).

At this time, when a voltage exceeding the threshold is applied to the stop terminal due to the influence of noise caused by static electricity generated in the gaming machine at timing T209 in the drawing (a motor stop signal (H level) due to noise). Even if the signal is input), the motor stop signal (H level) is invalidated because the mode is currently shifted to the output stop invalid mode. Therefore, in the motor driver 500, the output of the excitation data from the output control circuit 504 to the output circuit 505 is maintained, and a voltage is supplied to each excitation coil of the motor by keeping the transistor of the output circuit 505 on. As a result, the output of the motor M continues to be on at timing T210 in the drawing. Therefore, when the game machine is in operation, the motor driver 5
At 00, it is possible to prevent the motor M from malfunctioning by avoiding the influence of noise on the STOP terminal.

As described above, according to the present embodiment, in the motor control by the serial communication method, at the time of debugging in the development stage, a function for accurately stopping the output of the drive source (motor M) at the break point of the program is secured, thereby enabling debugging work. While the product can be operated efficiently, it is possible to avoid the malfunction of the drive source (motor M) due to the influence of noise or the like by preventing the function from causing a malfunction. Is possible.

Further, in the present embodiment, during debugging in the development stage, the production control board 200 and the motor driver 500 are connected by the connection line STOP to enable transmission / reception of the motor stop signal. By canceling and shorting the STOP terminal to ground,
It is possible to further improve the reliability of motor control by making it less susceptible to noise. Also, a switch means for short-circuiting the connection line STOP connecting the effect control board 200 and the motor driver 500 to the ground is provided, and by switching the switch means, the short-circuit is released at the development stage, and is connected to the ground when the product is in operation. You may make it short-circuit.

In addition, this invention is not limited to the said embodiment, If it is a range which does not deviate from the summary of this invention, it can improve suitably.

In the embodiment described above, each command is transmitted from the effect control board 200 to the motor driver 500 within the timer interrupt process on the effect control board 200 side. For example, command transmission at timings T100 and 100 in FIG. It is assumed that the command transmission is executed in the timer interrupt process of the Nth time (N + 1 period), and the command transmission at the timing T100, 100 is executed in the timer interrupt process of the N + 1th time (N + 1 period). That is, the excitation output command and the motor stop signal valid / invalid command are transmitted as one set for each interrupt cycle. However, the present invention is not limited to the case where the motor stop signal valid / invalid command is transmitted periodically (every interrupt cycle) as described above. For example, the motor stop signal valid / invalid command is transmitted only when the gaming machine is turned on. Alternatively, the output stop valid / invalid mode may be determined according to the setting when the power is turned on, and the mode may be maintained until the gaming machine is powered off. According to this configuration, it is possible to reduce the control burden on the control board and smoothly process the game progress or the game effect. Furthermore, the motor stop valid / invalid command is transmitted only when the mode is changed to the output stop valid mode, and the motor stop valid / invalid command is not transmitted, or the motor stop valid / invalid command cannot be received due to a communication error or the like. In this case, it may be configured to make a transition to the output stop invalid mode. According to this configuration, similarly to the above, it is possible to reduce the control burden on the control board, smoothly process the game progress or the game effect, and accurately switch the mode in accordance with a malfunction such as a communication error. Therefore, it is possible to prevent the occurrence of a secondary problem that the motor cannot operate properly.

In the above-described embodiment, the start and end of command data (serial data) capture in the communication circuit 501 are enabled in order to improve robustness against noise.
However, the present invention is not limited to this configuration. For example, a start code and an end code are set at the beginning and end of the command data, and the command data ( (Serial data) may be started and ended. In this case, the processing load of motor control is reduced.

In the above-described embodiment, serial data is transferred from the storage circuit 502 to the output control circuit 504 or the like in response to the input of the load signal. However, the present invention is not limited to this configuration, and the last bit ( The serial data is transferred when the 16th bit is input, or the serial data is transferred when the enable signal changes from the L level to the H level after inputting the last bit (16th bit) of the serial command. It may be. A load command may be set in the serial command.

Further, in the above-described embodiment, the movable accessory 24 that executes the effect operation according to the predetermined effect pattern is described as the movable means that executes the operation related to the game. However, the present invention is not limited to this configuration. For example, an electric combination (normal electric combination or special electric combination) that opens and closes a game ball in an easy or difficult state, or a payout member that pays out a number of game media according to the type of winning. For other movable means such as a ball feeding member for feeding a game ball to the launching mechanism, a launching member for hitting the game ball toward the game area, and a rotating reel that rotates by arranging multiple types of symbols in the circumferential direction. You may apply.
