When 10 stops, a message such as "7 will be out!" Is produced and displayed in the upper part of the display area of the special symbol display device 310. After that, the concealment symbol 1610 disappears, and one piece of identification information appears from behind. When the special stop result mode of “777” finally appears as in FIG. 17B, the opening and closing operation of the special winning opening 24 is repeated up to 16 times as a special game state. On the other hand, as shown in FIG. 17C, when the identification information appearing from behind the concealment symbol 1610 is different from that displayed in another display frame, the display game ends without a special stop result mode appearing. .

As described above, the concealment symbol that appears during the execution of the display game moves on the two or more pieces of identification information, and the occurrence of the special prize depends on where the concealment symbol stops. Gives unexpected surprises to attract interest.

FIG. 18 shows an example in which the concealment symbol 1610 moves irregularly. In the example shown in FIG. 18, the concealment symbol 1610 moves in a zigzag manner. Since the concealment symbol 1610 moves irregularly in this manner, it is difficult to predict where the concealment symbol will eventually stop, and the thrill and excitement of the player can be further aroused.

FIG. 19 shows a case where a plurality of concealed symbols move simultaneously. In this example, as shown in FIG. 19B, when a state in which the reach display mode does not appear and ends as it is, the concealment symbol 1610 and the second concealment symbol 1620 appear at the same time. These concealed symbols 1610 and 1620 include a left display frame 311, a middle display frame 312, and a right display frame 313, as shown in FIGS.
After moving for a predetermined period on a predetermined orbiting path passing through, the vehicle stops at any one of the locations.

As shown in FIG. 19E, two display frames 31
Stopping in a state of covering 1 and 312 again causes the possibility that the special stop result mode will appear when these hidden symbols 1610 and 1620 disappear. In FIG. 19f, after the concealment symbols 1610 and 1620 disappear, “77” is displayed.
7 "has appeared, and a special stop result mode has been formed.

As described above, if a plurality of concealed symbols appear, there is a possibility that a special stop result mode will occur regardless of the development of the game up to that time. Can be done. Even if only one concealment symbol appears, for example, if it stops at the position where the left display frame 311 in FIG. 19 is covered and “7” is stop-displayed in the middle display frame 312, after the concealment symbol 1610 disappears. Therefore, there is a possibility that a special stop result mode will appear.

As shown in FIG. 20, a larger number of display frames may be provided than the number of pieces of identification information necessary to configure the special stop result mode. In the example of FIG. 20, four display frames 3
11 to 314 appear, and when three of them “777” are aligned, a special stop result mode is formed. In FIG. 20c,
Since “7277” appears, if the concealment symbol 1610 stops on “2” as shown in FIG. 20D, a special stop result mode is formed at that point. On the other hand, when the game stops above “7” as shown in FIG. E, when the concealment symbol 1610 disappears, the result of the game depends on whether or not “7” appears from behind. When the symbol “7” appears from behind the hidden symbol 1610 as shown in FIG.
A special stop result mode is formed in line with “777”.

Next, the control of the game machine main body 1 will be described with reference to FIG.
This will be described with reference to flowcharts shown in FIGS.
FIG. 13 is a flowchart showing the operation of the main processing of the main substrate 100. When the power of the gaming machine body 1 is turned on,
One-chip microcomputer 10 mounted on main board 100
1, a reset signal is input. One-chip microcomputer 1
When the reset signal is input, the CPU 102 initializes the program counter (PC) and executes the program from the start address (step 001) of the main processing.

When the main processing is started, step 00
1 interrupt initialization is executed. In the interrupt initial setting, setting of an interrupt vector depending on the CPU 102 and setting of interrupt inhibition are performed. Subsequently, in the initialization of the hardware in step 002, the CPU 102
Set various devices and input / output interfaces to be connected. Here, a parallel I / O and a serial I / O are prepared for the input / output interface.

Next, in step 003, the input of the RAM initialization switch is confirmed. The RAM initialization switch is a hardware switch installed on the back of the game board 2. If this switch is pressed when the power is turned on, the input is determined by this processing and the processing branches. If the input has been confirmed, the process proceeds to step 005 to forcibly initialize the game information storage area. If there is no input, the process proceeds to step 004.

The power failure flag confirmation process in step 004 is a flag confirmation process for determining whether a power failure has been detected and the evacuation action of the game information storage area has been performed before. In this case, if the power failure flag is ON (1), it is determined that the above-mentioned action has been performed, and the processing branches to shift to the return operation of the game information storage area after step 012. on the other hand,
If the power failure flag is OFF (0), the next step 0
Move to 05.

In the initialization of the stack pointer in step 005, the pointer (address) of the stack area managed by the CPU 102 is initialized. In the initialization of the game information storage area in step 006, the minimum necessary parameters are set in addition to the clear processing, and the game information storage area is set at the time of factory shipment.

Activation of timer interrupt in step 007,
And permitting an interrupt is performed by setting a hardware timer connected to the CPU 102 and operating the timer,
The interrupt setting of the PU 102 is changed from the disabled state to the interrupt enabled (enabled) state, and the timer interrupt processing (steps 101 to 110 in FIG. 14) is operated.

The special symbol game process in step 008 is as follows.
The monitoring of the fluctuation time of the special symbol, the management of the random number for the special symbol, the control shift to the customer waiting demonstration screen, the monitoring of the opening time of the special winning opening 24, the monitoring of the winning number, the confirmation of the special symbol holding ball, etc. are performed. Details will be described in a subroutine described later.

The normal symbol game process in step 009 is as follows.
The monitoring of the winning count, the monitoring and operation of the fluctuation time, the confirmation of the ordinary symbol holding ball, the hit judgment, and the like are performed in accordance with the operation of the ordinary electric accessory solenoid 136.

The external information editing process of step 010 is a process of editing the signal information output from the external connection terminal board or the trial test signal terminal 116 and storing the edited signal information in the game information storage area. In the editing process of the signal information, a prize ball signal outputted every time a predetermined number of balls are paid out, a special symbol decision signal outputted every time the special symbol finishes changing and stops, and a normal symbol finishes changing and stops. Normal symbol confirmation signal output every time,
Output monitoring and setting of a special symbol hold signal for signaling and outputting the number of reserved special symbols and a normal symbol hold signal for signaling and outputting the number of reserved ordinary symbols are performed.

In the main random number updating process in step 011, a synchronization prevention random number corresponding to each stop symbol is extracted, and the random number for the stop symbol extracted in the timer interrupt process (FIG. 14) described later corresponds to each symbol random number. By adding the synchronization preventing random numbers, the symbols are prevented from stopping in the same order.

Steps 008 to 011 are repeatedly executed in the main processing. During this time, the timer interrupt operates and the timer interrupt process is executed in parallel, so that the gaming machine main unit 1 is in a playable state, and the game information storage area is updated.

The stack pointer return processing in step 012 is the power failure flag confirmation processing in step 004 described above.
The process moves when the power failure flag is ON (1). The stack pointer, which is part of the game information saved at the time of the power failure, is reset here.

The timer interrupt activation processing in step 013 is almost the same as the processing in step 007, except that the register return processing in step 014 is inserted between the activation processing in step 013 and the interruption permission processing in step 015. After the return process is completed, the timer interrupt process can be performed.

When the return process from step 012 to step 014 is completed, the CPU 102 is operated from the power failure execution address of a part of the game information storage area saved during the power failure. The process of setting the power failure flag OFF in step 016 is such that the process is not shifted to the power failure recovery process at the next power-on.

FIG. 14 is a flowchart showing the operation of the main board 100 in the timer interrupt processing. When the timer interrupt processing is enabled and becomes executable in steps 007 and 015 of the above-described main processing (FIG. 13), the timer interrupt processing is executed at set time intervals. During the repetitive processing from step 008 to step 011 of the main processing, a timer interrupt is activated and the processing described below is executed.

First, in the register save processing of the first step 101, C at the time when the timer interrupt processing is started is set.
The registers of the PU 102 are saved to the stack area. The input process of step 102 is performed by using information on various devices connected to the CPU 102 (starting port switch 121, winning port switches 122 and 123, ordinary symbol display device operation gate switch 126, glass door open detection switch 132, overflow switch 133, Shot ball out switch 13
1, a signal of the prize ball detection switch 130, etc.) is read from the input port via the input / output interface and stored in the game information storage area.

In the output process of step 103, game state information edited by other processes centering on step 010 of the main process is read from the game information storage area, and the output port is output via the input / output interface connected to the CPU 102. And outputs it as a signal to the special winning opening solenoid 134, the ordinary electric accessory solenoid 136, the ordinary symbol display device 310, the external terminal for the panel, and the external terminal for the frame.

In the command transmission processing of step 104,
The game control information edited by other processes is read from the game information storage area, and is output to various devices connected to the CPU 102 from the output port via the input / output interface. The output destination is a display control board 300, a lamp control board 400, a payout control board 200, a voice control board 500, and the like.

In the timer interrupt random number updating process of step 105, in addition to the contents of step 011 in the main process, a random number for jackpot determination, a symbol random number, a reach execution random number, a control pattern random number, and the like used for the jackpot lottery are updated. I do.

The random number for the hit determination is determined by the special symbol display device 31.
This is a random number for determining in advance the probability for determining whether to generate a jackpot as a result of the variable display of the symbol at 0. The random number for the hit determination is composed of, for example, a numerical value of 0 to 299. The random number is counted up by one at every random number update process. It is configured to count up again by one. For example, if the lottery result is 5
If it is 9, the count is incremented by 1 from 59 to 58, starting at 59.

The symbol random numbers are used to determine each stop symbol specified as the display result of the special symbol display device 310, and each of the symbols has a value of 0 to 9 and counts up by one at a predetermined timing. When the upper limit value ("9") is reached, the count is restarted from 0.

The reach execution random number determines whether or not to perform a special effect until the last stop symbol is determined when the reach display mode appears. Count up by one for each update process,
When the upper limit (“14”) is reached, the count is restarted from 0.

The effect pattern random number determines various control patterns at the time of execution of variable display, and is composed of, for example, a value of 0 to 5, and is incremented by one for each random number update process, and the upper limit value (“5”) ) Is configured to count up from 0 again.

In the timer updating process of step 106, the special symbol display device 310 outputs the time from the start to the stop of variable display of various symbols, the display (lighting) time of the ordinary symbol display device 140, and the payout control signal for a fixed time. Update the software timer (counter) and so on. In these control processes, the signal is turned on while monitoring this timer.
/ OFF is controlled.

The error updating process of step 107 is a process of monitoring payout sensor information, which is one of the information obtained in step 102, for a certain period of time, and detecting an error by confirming the movement of the ball. If the movement of the ball cannot be confirmed by the payout sensor, the error information is updated because it is considered that the ball is clogged on the passage before the sensor position. In addition to the error monitoring based on the payout sensor information, the open / close state information of the glass frame on the front of the gaming machine is monitored in the same manner, and when the glass frame is opened, the error information is updated.

The switch monitoring process in step 108 reads the state information of each sensor and switch input in step 102 from the game information storage area, and updates the game state information. The target sensors and switches here are the starting port switch 121, each winning port switch 1
22, 123, an accessory continuous operation operation switch 124, a count switch 125, a prize ball detection switch 130, a normal symbol display device operation gate switch 126, etc. relating to ball detection. It is generated and edited as state information and stored in the game information storage area.

In the register return processing in step 109, the contents of the register saved in step 101 are returned to the CPU 102 from the stack area. The timer interrupt permission process of step 110 permits the next timer interrupt process.

FIG. 15 is a flowchart showing the operation of the NMI interrupt processing of the main board 100. The NMI interrupt process is started by a power failure detection signal output from a power failure detection circuit 709 in the power supply board 700. CPU1
When a power failure detection signal is input to the 02, NMI interrupt processing is executed, and the following contents are processed.

First, in the register saving process of step 201, the register of the CPU 102 at the time of detecting a power failure is saved in the stack area. At this time, the contents of the register are saved, but before this, the address immediately before the NMI interrupt is automatically saved. The power failure flag ON setting process of step 202 is a process of detecting a power failure and setting the execution of the power failure detection process as a flag in the game information storage area.

The game information storage area access prohibition process in step 203 is a setting process for prohibiting access (read / write) to the game information storage area by hardware. Access to the game information storage area becomes impossible in the subsequent processing, and the game information storage area is protected. With this, the evacuation action of the game information storage area at the time of the power failure is completed, and the CPU 102 enters an infinite loop without terminating the NMI interrupt processing itself.
And wait until the power supply is completely cut off.
This is because if the NMI interrupt processing is terminated, there is time until the power supply is completely cut off, so that the timer interrupt is processed and the operation becomes undefined.
