Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a prize ball discharge control system for a pachinko game machine, and in particular to an output signal from a winning ball detector that electrically detects winning game balls in the winning section. The present invention relates to a prize ball ejection control system for a pachinko game machine that controls the ejection of prize balls in accordance with the situation.

[Prior Art] A winning ball detector electrically detects winning game balls (winning balls) in various winning parts provided in the gaming area of a pachinko game machine, and detects the winning balls based on the output signal of the winning ball detector. A prize ball control system for a pachinko game machine is known, which discharges a predetermined number of prize balls a number of times according to the number of winning balls.

[Problems to be Solved by the Invention] By the way, in the island equipment of a pachinko game parlor where the game machines are actually installed, dirt, dust, or heat tends to accumulate inside the equipment, so that it is difficult to electrically hit winning balls. The conditions for using the winning ball detector described above for detecting are not appropriate, and noise is likely to occur in the output signal of the winning ball detector. In addition, the pachinko game ball itself detected by the winning ball detector,
Because it circulates inside the island of the game arcade, it becomes charged with static electricity due to friction with the flow paths such as the storage tank, drain gutter, and supply tray while flowing down the flow paths. This charged game ball causes noise to be generated in the output signal of the winning ball detector.

When controlling the ejection of prize balls, the noise generated in this way is treated in the same way as a signal when a winning ball passes through the device, and the generation of this noise may cause incorrect ejection of prize balls. There was a problem where the

Furthermore, devices that electrically detect the presence of game balls, such as the above-mentioned winning ball detector, not only generate noise, but also
When a foreign object enters the device, the output signal changes and a waveform is output as if a game ball has won a prize, resulting in the wrong prize balls being ejected. .

In addition, in the prize ball control system of conventional pachinko gaming machines, the winning balls detected by the winning ball detector are configured to pass through the detector and be released to the outside without being stored. , it was not possible to adequately deal with the occurrence of a failure in the winning ball detector itself. In other words, if a malfunction occurs in the prize winning ball detector, confirmation of the occurrence of a malfunction is when the player points out that the prize ball is not ejected even though the game ball has won, and the staff member actually plays the game ball. This was done by inserting the prize ball into the winning part of the board (inside the detector) and making sure that the prize ball was not ejected. Therefore, when it is confirmed that the winning ball detector has malfunctioned, the undetected winning balls have already been released to the outside, and it is not possible to determine how many winning balls have been invalidated due to the malfunction. First, there was a risk that trouble would arise between the player and the game parlor over the number of prize balls that were not ejected, and the relationship of trust between the game parlor and the player would be damaged.

[Purpose of the Invention] The present invention has been made in view of such problems, and aims to improve the accuracy of winning ball detection by monitoring the output signal from a winning ball detector that electrically detects winning balls. A malfunction state of the winning ball detector can be quickly detected using the monitored signal, thereby preventing troubles between game parlors and players regarding the number of prize balls that were not ejected due to a malfunction of the winning ball detector. The purpose of the present invention is to provide a prize ball discharge control system for a pachinko game machine that can perform the following functions.

[Means for Achieving the Object] In order to achieve the above object, the prize ball discharge control system for a pachinko game machine of the present invention includes a winning ball detection means for detecting a winning ball and outputting a pulse signal as a detection signal; A pulse width detecting means for measuring the pulse width of the pulse signal, and determining that the ball is a winning ball when the pulse width measured by the pulse width detecting means is within a predetermined appropriate range. Winning ball determining means for outputting a winning signal; and a failure for outputting a failure signal when it is determined that the pulse width measured by the pulse width detection means is within a predetermined range of failure. A configuration comprising a detection means, a prize ball ejecting means for ejecting prize balls based on a winning signal from the entered prize ball determining means, and a failure processing means for performing failure processing based on a failure signal from the failure detection means. It becomes.

[Function] As described above, in the prize ball discharge control system of the pachinko game machine of the present invention, the winning ball determining means determines the winning ball based on the pulse width of the output signal of the winning ball detecting means detected by the pulse width determining means. It is determined whether the signal from the ball detection means indicates a winning ball or not, and the ejection of the prize ball is controlled according to this result, so the ejection of the prize ball is performed more accurately than in the past. It turns out. In addition, since the structure is such that a failure of the winning ball detection means itself can be detected based on the signal representing the pulse width from the pulse width detection means, the occurrence of a failure can be detected quickly, and compensation will be provided for any disadvantages caused by the occurrence of the failure. can be carried out smoothly and accurately.

As shown in the figure, it includes a safe bulb detection section 830A, a pulse width detection section 830B, and a short detection section 830C.

Of these, the safe detection section 830A normally (when there is no winning ball inside) has a potential on the 8 force side (point A) that is a value that turns on the transistor Tr of the pulse width detection section 830B (for example, 6.5V: L). level). Further, when there is a winning ball inside, the potential on the output side (point A) changes to a value (for example, 12■: H level) that turns off the transistor Tr of the pulse width detection section 830B.

The pulse width detection section 830B is connected to the safe detection section 83.
It is determined whether the change in the output signal (potential at point A) obtained by the action of 0A is due to the winning game ball actually passing through the safe detection section or whether it is due to noise or the like.

More specifically, the pulse width detection section 830B includes a resistor R
1 to R1, transistors Tr, capacitor C1, and an inverter. Of these, the resistor R and capacitor C1 form an integrating circuit, and the noise of the waveform appearing at point B is removed by the function of this integrating circuit. It will be done. Note that the width of the noise removed by the integrating circuit can be adjusted as appropriate by the capacitance of the resistor R1 and the capacitor C1.

An example of this circuit constant is shown below for reference.

Next, the procedure for controlling the ejection of prize balls performed by the above-mentioned prize ball ejection control device 600 will be explained in detail with reference to FIGS. 14 to 36.

The ejection control of the prize balls is performed by a so-called background control process (FIG. 14) that starts at the same time as the power of the prize ball ejection control device 60o is turned on and is repeated as long as the power is turned on, and a background control process (FIG. 14) when the power is turned on. There are two interrupt processes (Fig. 18) in which the background control process is interrupted every predetermined period of time (for example, 0.5 m5ec) after the input. These two control processes are executed by the MPU 620 in the device 600. Note that in the background processing that is performed between the start of one interrupt processing and the start of the next interrupt processing, one loop of processing (steps 88 to 519) is performed.
) is performed multiple times.

First, the main routine of the background control process for controlling the ejection of prize balls will be explained with reference to FIG.

This main routine is repeated after the power of the prize ball ejection control device 600 is turned on as described above.

When the power is turned on, first, in step s2, it is determined whether the "safe storage value" is rQJ or not.

This "safe memory value J is determined in the safe ball judgment process (Fig. 28) of the interrupt process (Fig. 18) described later, and each time it is determined that the safe ball has passed inside the safe sensor, The value is added to 1, and conversely, every time a predetermined number of prize balls corresponding to one safe ball (for example, 13) are ejected in the ejection process (Figure 32), the value is added to I. is subtracted.

When the determination result in step S2 is "Yes", the process advances to step S4, and the RAM 622 in the MPU 620
Clearing the memory contents of , resetting various discrimination flags used in various subroutines described below (set to "o"), clearing various operating parts (various solenoids,
Output resets (setting the outputs to L level) to various lamps, etc.) are sequentially performed, and after such initialization, the process proceeds to step S8 and subsequent steps.

On the other hand, the determination result in step S2 is 'N'.

In other words, at the start of this program, the safe memory value is rlJ.
When the above value is reached, in other words, at the end (or interruption) of the series of control programs that were being executed before this program started, the safe balls that have been confirmed to have won until then are If the number of prize ball discharges corresponding to the number of prize balls has not been completed yet, the process proceeds to step S6, and the safe balls that have not yet been discharged (hereinafter referred to as "Ero remaining balls J") are Ejected remaining ball indicator lamp unit 4 that is lit (ON) to indicate that remaining balls remain.
45c is demagnetized (OFF), and then the process proceeds to step S8 and subsequent steps. If there is, the light will be lit to indicate that there are balls remaining to be ejected in the power down process (FIG. 36) to be described later).

In the following steps S8 and SIO, it is determined whether the processing number is '2'' and whether it is II I ++, respectively.

This process number (processing number) starts the discharge start process (Fig. 29) described later when its value is '1', and starts the discharge process described later (Fig. 32) when its value is '2'. Then, the step S4, which is executed immediately after the power is turned on, or the discharge process (third
When the ejection of a predetermined number (for example, 13) of prize balls is completed in Figure 2), the value is reset to 'O'', and the reset process number has a safe memory value of rQJ at that point.
When it is determined that this is not the case, the value is immediately reset to "1" (step S12520, which will be described later), and the discharge start process is then started again.

Furthermore, processing N immediately before the discharge start processing is ended.

The value is set to '2'' and the discharge process is subsequently started.

The processing procedure will be explained in sequence according to the flow.

Consider the case where the safe memory value at this time is "O" immediately after power is applied to the metal plate (at this time, all control variables and control flags are set as If O++ in step S2).
).

At this time, step S8. Both SIO discrimination results are I.
NoI+, and it is determined in step S12 whether or not the safe storage value is rQJ. In this case, the determination result is "Yes", and in step S14, a memory clearing process (described later in FIG. 15) of the safe memory value based on the output signal of the memory clearing switch is performed, and in subsequent step S1
After performing a replenishment process (FIG. 16), which will also be described later, in step S6, it is determined in step S17 whether or not the safe error flag is '1'.

This safe error flag is set based on the level of the output signal of the safe sensor 830 in the safe ball determination process (FIG. 28) described later, and when the value is "1" (details will be described later). (When the output signal is held at H level for an abnormally long time or when a short circuit is detected) This indicates that an abnormality (or fraud) has occurred in the safe sensor.

When the determination result in step S17 is 1Nou, the process directly advances to step S18, and the number of winning balls (safe memory value) stored at this point is stored in the winning ball discharging device 60.
After displaying on the winning pitch number display 613 provided at 0,
The process starts again from step S8.

On the other hand, the determination result in step S17 is 1lyesI+
In this case, the process advances to step S19 to perform error recovery processing (FIG. 17), which will be described later, and then restarts the process from step S8.

While the above-mentioned steps 88 to S19 are repeatedly executed, it is newly confirmed that a safe ball has actually won a prize by executing the safe ball determination process (see FIG. 28 described later) in the interrupt process (see FIG. 18). When the confirmation is made and 1 is added to the safe memory value, and as a result, the value becomes "1" or more, step S12 is performed.
The determination result changes to "No++" and step S20 is executed.

In step S20, the process NO is set to ++ 1 ++, after which steps SL4 to S19 are executed, and the process starts again from step S8.

In the next process, the process NO is set to II I ++, so the determination result in step SIO changes to "Yes," and the discharge start process (FIG. 29) is performed in step S22.

This discharge start process, as will be described in detail later, is performed prior to the discharge process (see FIG. 32 described later), and is performed for the set number of prize balls (for example, 1 to 15) stored in the prize ball setting device 530.
This process involves pre-selecting the ejection pattern (single ejection, alternating ejection, combined ejection) of the prize balls based on the range (set within the range of In the discharge start process, the process N
The value of O is changed to "2pa".

When this discharge start process is completed, steps S14 to S19 described above are executed, and then step S8 is performed again.
Processing will be resumed from.

In the next loop, since the process number is set to "2'", the determination result in step S8 changes to Yes and the discharge process (FIG. 32) is started (step 524).

As will be described in detail later, this discharge process is to discharge a predetermined number of prize balls (set number of prize balls) a number of times corresponding to the safe memory value, and as will be described later, the above predetermined number of prize balls are discharged. Once the discharge is completed, the processing number is temporarily set to ``0''. In the loop immediately after that, the step S
8. Both SIO determination results are "NO", and the determination in step S12 is performed again.At this time, if the safe storage value is not rQJ, the determination result in step S12 is I No+-, and the process is NO. is set to ``BI'', and the discharge start process and discharge process are restarted. The safe storage value is subtracted by 1 for each series of such processing, and the discharge processing is repeatedly executed until the safe storage value reaches rQJ.

Thereafter, the process of ejecting the prize balls of constant A is performed the number of times corresponding to the safe memory value, and as will be described later, in the ejection process, the processing number is reset to ((O++). As a result, the subsequent loop Step S8 again
．． Both SIO determination results are II No I+, and further determination in step S12 is performed.

When the determination result in step S12 is 11 NoI+ (safe memory value≠O), the processing NO is set to ``BI'' (step 520), and the ejection control of the prize balls is performed again. If "Yes", steps 88 to S18 or step S19 will be repeatedly executed until a new winning ball is detected by safe sensor input processing, which is an interrupt processing that is performed separately from this main routine.

FIG. 15 is a flowchart showing the subroutine of the memory clearing process carried out in step S14 of the main routine (FIG. 14) of the above-mentioned prize ball ejection control.

When this routine starts, first step 51402
In step 51404, it is determined whether the memory clear flag is "'1" or not.
+, it is determined whether or not.

This memory clear flag changes from the L level (“O”) to the H level (''1'') in the memory clear switch input process (Fig. 26) executed in the interrupt process described later. When the ball is turned, the value is set to "'1", and the processing number is set to "'1", as described above, the reset processing (
Step S4) or when the discharge process is completed, the value is “0”
is reset to "'1" in step S20 of the main routine when the ejection of prize balls is started (when the safe memory value becomes "1" or more), and is further set to "'1" in the ejection start process. 2++, which determines the control flow of the main routine as described above.

Said step 51402. If the determination result of either step 51404 is NO, that is, the memory clear switch is not pressed, or the ejection process of the prize ball is not completed, then step 51406 and step 51 continue.
Skip step 408 and end this routine.

On the other hand, when the determination results in steps 31402 and 51404 (7) are both II Yes esI+, the safe storage value is reset to rQJ (step 51406), and the memory clear flag used for the determination in step 51402 is reset to 110++. (step 514)
08), this routine ends.

FIG. 16 is a flowchart showing the subroutine of the replenishment process carried out in step S16 of the main routine (FIG. 14) of the above-mentioned prize ball discharge control.

When this routine starts, it first starts at step 51600.
At this point, it is determined whether or not the replenishment sensor rise flag, the value of which is determined in the replenishment sensor input process (FIG. 22) performed in the interrupt process described later, is "1". When this determination result is IYeSI+, that is, when there are no prize balls up to the installation position of the supply sensor 211 of the storage tank 201 due to the ejection of the prize balls, the completion lamp is turned on to indicate that there is a shortage of prize balls (step 51604). ),
The shutter solenoid is set to prohibit the firing of game balls.
ON” (step 51606), the external information relay is “ON” (step 31608), and the replenishment sensor startup flag is returned to 0” (step 5161).
0), this routine ends.

When the determination result in the step 51600 is "NO++", it is determined in the following step 51602 whether or not the replenishment sensor fall flag, whose value is determined in the replenishment sensor input process described later, is '1''. When this determination result is "IIYeSl", that is, when the prize ball has reached the installation position of the replenishment sensor 211 of the storage tank 201 after replenishment, the completion lamp is turned OFF (step S1612), and the game ends. The shutter solenoid is turned "OFF" to enable the ball to be fired (step 516).
14), turn off the external information relay (step S1616), and turn off the replenishment sensor fall flag.
It returns to I OJ+ (step S 1 618) and ends this routine.

FIG. 17 is a flowchart showing a subroutine of error recovery processing performed in step S19 of the main routine (FIG. 14) of the above-mentioned prize ball ejection control.

When this routine starts, first step 51702
It is determined whether the recovery ON flag is "1" or not. This recovery ON flag is determined by the recovery switch input process (FIG. 27), which will be described later, based on the output signal of the recovery switch 780.
If the value is "1", it means that the lock solenoid 72 has been temporarily demagnetized (turned OFF) due to fraud, etc. by an employee at the game parlor pressing the switch.
1 is forcibly re-energized (ON) to restart ejection of prize balls.

Therefore, the flag is IIQI+ (step 51702
If the result of the determination is lN o++ ), the following steps 51704 to 51708 are skipped and the routine ends. On the other hand, when the determination result in step 51702 is "'Yes", the main routine (first
The safe error flag used for the determination in step S17 in Figure 4) is reset to 0'' (step 51704).
), proceed to step 51706.

Steps 51706 and 51708 cancel the process performed when the output signal from the safe sensor is determined to be abnormal in the safe ball determination process (Figure 28) (processing at the time of sensor failure), as will be described in detail later. Processing is performed. That is, in step 51706, the motor control relay, which was deactivated (OFF) when the sensor failed, is again driven (ON) L, and then in step 51708, it is also demagnetized when the sensor fails to prevent the ejection of the prize ball. The safe bulb outflow prevention solenoid 851 is energized (ON) again to cancel the error processing and end this routine.

Next, the main routine (background processing) described above (Fig. 14) is given priority and
) The detailed procedure of the interrupt processing performed each time the process progresses will be explained with reference to FIGS. 18 to 28.

As shown in FIG. 18, when the interrupt process is started, first, the count values of various timers such as a discharge wait timer and a safe ball wait timer, which will be described later, are updated (step 842), and then the discharge sensor 1 input processing (step 544), and input processing of the discharge sensor 2 (step 546).
), safe sensor input processing (step 548), replenishment sensor input processing (step 550), incomplete sensor input processing (step 552), overflow switch input processing (step 554), firing motor control processing (step 556), Memory clear switch input processing (step 558), recovery switch input processing (step 560), and safe ball determination processing (step 562) are sequentially performed.

FIG. 19 is a flowchart of the input processing routine for the discharge sensor 1 carried out in step S44.

When a prize ball is present in the sensor, the output signal of the discharge sensor 1 (and discharge sensor 2, which will be described later) becomes H level, and the prize ball floats and temporarily or continuously enters the sensor. The configuration is such that when it no longer exists, its output signal goes to L level. Therefore, in this flow, when the output signal rises from the L level to the H level (when the ejection sensor 1 rise flag = "1" and the ejection sensor 2 rise flag = "1", which will be described later), the prize ball is determined to have reached the inside of the sensor.

When this routine is started, first, in step 54402, it is determined whether or not the discharge 1 change flag is II II II.
In the following step 54404, the discharge IL level flag is set to l.
′” is determined.

By the way, as described above, all the discrimination flags are set to 0'' in step S4 of the main routine (FIG. 14) immediately after the power is turned on to the prize ball discharge control device 600.

Therefore, when this routine is executed immediately after the interrupt processing is started for the first time, the determination results in steps 54402 and 34404 are both i regardless of the output signal level of sensor l.
tN oI+, and first, in step 54406, the output signal in this loop becomes L level (emission sensor 1 output = "
O'') is determined.

From the state where the prize ball remains in the discharge sensor 1 on the metal plate, the prize ball is moved to the supply tray 1 by actuation of the discharge solenoid 1.
Let us consider the case where the liquid is discharged to the 02 side.

While the prize ball remains on sensor 1, the output signal of sensor 1 remains at H level, so the determination result in step 54406 is "N".

Then, this routine ends as is (steps 34402 to 54406 are repeated after initialization until the output signal of sensor 1 changes to L level for the first time).

When the prize ball in the ejection sensor 1 moves from this state (gets out of the sensor 1) and the output signal of the sensor 1 changes from the H level to the L level, the determination result in step 54406 becomes 'Yes'. , proceeds to step 54408, and sets the discharge IL level flag to '1'' in order to remember that the output signal of sensor 1 has become L level in this loop.
Set this to end this routine.

When proceeding to the next loop, the step 34 of the previous loop
Since the discharge IL level flag is set to "1" by the process in step 408, the determination result in step 54404 is 'Yes'.
” and proceeds to step 54410, where the output signal of the discharge sensor 1 in this loop is set to H level (discharge sensor 1f).
fi car "l"). If this determination result is llN0'', that is, the output signal is at L level in the current loop as well as in the previous loop, the following step 4
412, skipping step 54414 and ending this routine. Therefore, steps 54402, 54404, and 54410 are repeated as long as the output signal is at L level.

On the other hand, if the determination result is "Yes", that is, if the output signal of the discharge sensor 1, which was at the L level until the previous loop, rises from the L level to the H level before moving to the current loop, the rising edge will not be detected in the current loop. The discharge 1 change flag is set to "1'" to remember that this happened (step 54412), and the discharge IL level flag is set to 0" to remember that the output signal in this loop is no longer at the L level. to end this routine.

In the loop immediately after the output signal of the discharge sensor 1 rises, first, in step 54402, it is determined whether the discharge 1 change flag is "1".

In this case, the determination result is ii y eS=+, and in the subsequent step 54416, it is determined whether the output signal of the discharge sensor 1 is still at the H level in this loop.

When this determination result is "Yes", that is, when the output signal of the discharge sensor rose in the previous loop and is still maintained at the H level in the current loop,
It is determined that the prize ball has reached the ejection sensor 1,
The discharge sensor 1 startup flag, which is used as a sensor output in the alternate discharge process (FIG. 34) described later and the combined discharge process (FIG. 35) described later, is set to "1" (step 5441).
At the same time as 8), the discharge 1 change flag that stores the rising edge of the output signal is reset (set to "0'') (step 54420), and this routine ends.

In the subsequent loop, as long as the output signal still maintains the H level, steps 54402, 54404, and 5440 are performed.
6 will be repeated.

On the other hand, the determination result of step 54416 is “l N
When or+, that is, when the output signal falls again in the loop immediately after the output signal rises, it is determined that this change in the output signal is not due to the passing of the prize ball (such as the generation of a noise signal), and the current loop After remembering that the output signal at is at L level (step 54422),
In step 54420, the discharge 1 change flag is reset (set to II OII) (the rise that occurred this time is determined to be due to noise and is invalidated),
This routine ends.

By executing the above routine, the discharge sensor 1
After the output signal rises, the discharge sensor l rise flag is set to "1" only when that state is maintained for a predetermined period or longer (while the interrupt processing is performed at least twice). The flag comes to indicate that the prize ball has reached the ejection sensor 1. In addition, this discharge sensor 1 startup flag is set immediately after it is used for discrimination in the alternate discharge process or combined discharge process (see Figures 34 and 35 described later) in the background process (main routine). will be reset. By the way, the processing routine including the above discharge processing of the main routine is to be executed multiple times between the end of one interrupt processing and the start of the next interrupt processing, so this flag is The next interrupt process (input process for the discharge sensor 1) will not be performed while ' is in the state of "1".

FIG. 20 shows step S46 of the interrupt processing (FIG. 18).
3 is a flowchart of an input processing routine of the discharge sensor 2 performed in the flowchart of FIG. This flow is performed in the same procedure as the input processing routine of the discharge sensor 1 described above.

When the power of the prize ball ejection control device 600 is turned on and all determination flags are set to "O" in step S4 of the main routine, this routine is started by interrupt processing.1. First, in step 54602, the discharge 2 change flag is set to “
In the following step 54604, it is determined whether the discharge 2L level flag is "1" or not.

The determination results in steps 54602 and 34604 are If N on regardless of the output signal level of sensor 2 (all flags are set to "OII"), and in step 54606, the output signal in the current loop is at L level (
It is determined whether the discharge sensor 1 output = II OII ).

From the state where the prize ball remains in the discharge sensor 2 on the metal plate, the prize ball is moved to the supply tray 1 by actuation of the discharge solenoid 2.
Let us consider the case where the liquid is discharged to the 02 side.

While the prize ball remains on the sensor 2, the output signal of the sensor 2 remains at H level, so the determination result in step 54606 is "'N."

When the prize ball in the ejection sensor 2 moves (gets out of the sensor 2) and the output signal changes from the H level to the L level, the determination in step 54606 is made. The result is II Y eS
I+, the process proceeds to step 34608, and the discharge 2L level flag is set to "111" to remember that the output signal of sensor 2 was at L level in this loop, and this routine ends.

When proceeding to the next loop, the step 54 of the previous loop
Since the discharge 2L level flag is set to II II II in step 608, the determination result in step 54604 is “Ye”.
s", and in step 54610, it is determined whether the output signal of the discharge sensor 2 in the current loop is at the H level (the output signal of the discharge sensor 2 = "1"). This determination result is II N o, that is, when the output signal is at L level in the current loop following the previous loop, the following step 546
12,54614 and ends this routine.

Therefore, as long as the output signal is at the L level, step 5460
2.54604 and 54610 will be repeated.

On the other hand, if the determination result is 11 y eSll, that is, when the output signal of the discharge sensor 2, which was at the L level until the previous loop, rises from the L level to the H level before moving to the current loop, there is a corresponding rise. To remember this, the discharge 2 change flag is set to 1111+ (step 54612), and the discharge 2L level flag is reset (set to "O") to remember that the output signal in this loop is no longer at L level. ) to end this routine.

In the loop immediately after that, that is, in the next loop in which the output signal of the discharge sensor 2 rises, first, step 54602 is performed.
That is, it is determined whether or not the discharge 2 change flag is B I II. In this case, the determination result is "Yes", and then in step 84616 the discharge sensor 2
It is determined whether the output signal of is still maintaining the H level in this loop.

When this determination result is 11 y eSll, that is, when the output signal of the discharge sensor rose in the previous loop and is still maintained at the H level in the current loop,
It is determined that the prize ball has reached the ejection sensor 2,
Alternate discharge processing (Fig. 34) and combined discharge processing (Fig. 3) will be described later.
5), the discharge sensor 2 startup flag used as the sensor output is set to II 1 H (step 8461).
8), the discharge 2 change flag that stores the rise of the output signal is reset (set to II O1+) (step 54620), and this routine ends.

In the subsequent loop, as long as the output signal still maintains the H level, steps 54602, 54604, and 5460 are performed.
6 will be repeated.

On the other hand, the determination result in step 54616 is “N ol
When the output signal falls again in the loop immediately after the output signal rises, these changes in the output signal are not due to the prize ball reaching the sensor mounting position (noise signal generation, etc.) After determining that the output signal in this loop is at the L level (step 54622), the discharge 2 change flag is reset (set to "0") in step 54620 (when the output signal that has occurred this time It is determined that the rise is due to noise and is invalidated), and this routine is ended.

By executing the above routine, the discharge sensor 2
The discharge sensor 2 rise flag is set to "l"' only when that state is maintained for a predetermined period or longer (while the interrupt processing is performed at least twice) after the output signal of
Therefore, the rising flag indicates that the prize ball has reached the ejection sensor 2. Note that this discharge sensor 2 start-up flag is similar to the above-mentioned discharge sensor I start-up flag, and can also be used for alternate discharge processing or combined discharge processing in the background processing (main routine) (see FIGS. 34 and 35 described later). It is reset immediately after being used for discrimination.

Since the processing routine including the above discharge processing of the main routine is to be executed multiple times between the end of one interrupt processing and the start of the next interrupt processing, the main routine The next interrupt process (input process for the discharge sensor 2) will not be performed while the flag is in If l II state.

FIG. 21 is a flowchart of the safe sensor input processing routine performed in step S48.

As mentioned above (Figure 5), when a winning ball is present in the safe sensor, its output signal (voltage level at terminal B) becomes H level, and the winning ball flows out and temporarily Alternatively, the output signal is configured to go to L level when the sensor no longer exists in the sensor. Therefore, in this flow, when the output signal rises from L level to H level (safe rise flag = KL I II
) It is determined that the winning ball has reached the sensor, and when the output signal goes from H to bell and falls to L level (safe fall flag == 111 +"), it is determined that the ball has passed through the sensor. It has become.

Consider the sensor output in a state where no game ball has won a prize on the gold plate.

In this state, the power is turned on to the prize ball discharge control device 600,
When the routine is started, first, in step 54802, it is determined whether the output signal of the sensor 830 is at the H level (safe sensor 8 force==II I++). In this case (when the game ball has not reached the sensor installation position), the determination result is "N".

The process then proceeds to step 34804 and subsequent steps.

In the next step 54804, the safe fall change flag is set to I.
In step 54806, it is determined whether the safe rising change flag is "it 1 ++", and in step 54808 "'r-", it is determined whether the safe H level flag is "'l". but then step 5481O
Then, it is determined whether the safe level flag is '1' or not.

By the way, immediately after the MPU 620 is initialized, all flags are set to "'0", so steps 54804~
All the determination results in 54810 are "No", and in step 34812, the safe high level flag is set to "'1" to remember that the output signal of the safe sensor was at L level in this loop, and the routine returns to step 34812. end.

Since the safe high level flag is set to "'1" in the subsequent loop, steps 54802 and 54804 are performed as long as the output signal of the safe sensor remains at L level.
, 54806, 54808, and 54810 are executed repeatedly.

Thereafter, when the game ball wins and the game ball (safe ball) reaches the installation position of the safe sensor 830 in the winning ball lead-out gutter 820, the output signal of the safe sensor 830 changes to H level, and the step 34802 The determination result is “Yes”
"" and steps 84830 and subsequent steps are executed.

When the processing after step 54830 is performed for the first time, the safe high level flag is '1'' and all other flags are II O++.
Both the results of the determination in step 4830 (whether the safe rising change flag is "'1") and the determination in the next step 54832 (whether the safe falling change flag is II I ++) are II
NoI+, the result of determination in the following step 54834 (although the safe level flag is II 1 F+) is Lr
Yes es++ and step 54836.34.83
8 is executed.

In step 54836, the output signal of the safe sensor 830 changes from the L level to the H level from the previous loop to the current loop.
In order to remember that the level has changed (rise), the safe high level change flag is set to 1111+, and in the following step 34838, the safe high level flag, which was set to '1' until the previous loop, is reset ('0'). ”) and
This routine ends.

When the output signal of the safe sensor 830 is still at H level in the next loop, step 54836 of the previous loop is executed.
Since the safe rise change flag is set to ``BI'' in step 34830, the determination result in step 34830 is =l v es++
Turn to Then, the following steps 54840 to 5484
In step 6, the safe sensor start-up flag is set to II II II in order to remember that the safe ball has reached the safe sensor 830 installation position in the winning ball lead-out gutter 820 (step 348
40) and when the value is 1'', the sensor 830
Set the safe sensor fall flag (set to "O11" when this step is executed for the first time after initialization) to 0, which indicates that there is no safe ball at the installation position (after the safe ball has passed). Step 5484
2) Next, the safe rise change flag is reset to 'O°' (step 84844), and the replenishment H level flag is set to remember that the output signal of the safe sensor 830 in this loop is at the H level. 1'' (step 54846) and ends this routine.

In the next and subsequent loops, if the output signal of the safe sensor 830 is at H level, the safe rising change flag, safe falling changing flag, and safe high level flag are all “IQ”.
++, since the safe H level flag is "1", step 34802. S4830.54832
, 54834 and step 54848 (determining whether the safe level flag is II II II) are repeatedly executed (the determination result of step 54848 is l y
esI+), at this time the safe sensor rise flag is held at r 1 n and the safe sensor fall flag is held at '0''.

On the other hand, the output signal of the safe sensor 830 changes from L level to H level.
In the loop immediately after falling to the L level, if the output signal falls to the L level again (step 34836 was executed in the previous loop and the safe rising change flag became "1'", and in the current loop If the sensor high force has fallen to the L level, step 548
The determination result of 02 is changed to II No I+, and the determination result of step 54804 is "No", step 548
The determination result of step 06 is determined as ii y es++, and in step 54828, a safe falling change flag is set to pavi' to remember that the output signal fell from the previous loop to the current loop, and the step At S, 4829, the safe rise change flag set in it 1 u during the previous loop is reset to O'', and this routine ends.

As a result, the safe rise flag is set to "1'' unless the H level state is detected for a predetermined period of time or longer (at least while this interrupt processing is performed twice) after the output signal of the safe sensor 830 rises. (indicating that the safe ball has reached the sensor 830 setting position in the winning ball derivation gutter 820) processing is not performed, so that it can be handled in cases where noise occurs in the output signal of the safe sensor. It has become.

Next, consider a case where the safe ball reaches inside the sensor 830 and the safe start flag is set to II III, and from this state the safe ball flows down and is located outside the sensor.

First, in step 54802, it is determined whether the output signal of the sensor 830 is at H level (safe sensor 8 force = "'1"), but in this case, the determination result is llN0+
1, and the determination in step 34804 is performed.

In this case, the determination result in step 34804 is II No
++, and in step 54806 it is determined whether the safe rise change flag is "1". At this time, the determination result in step 54806 is also "'NO" (set to "'0" in step 54844), and the process proceeds to step 54808, where the safe-be-level flag is set to pulse.
``'' is determined.

At this point, the safe level flag is set at step 34.
Since it is set to "1'" in 846, step 34
The determination result of 808 is ll y es I+, and the process proceeds to step 34814, where the safe rising edge is set to remember that the output signal of the safe sensor 830 changed from the H level to the L level (falling) from the previous loop to the current loop. The lower change flag is set to “1” and the subsequent step 548
16, reset the safe level flag that was set to ``1'' until the previous loop (set it to 110II),
This routine ends.

Furthermore, when the output signal of the safe sensor 830 is still at L level in the next loop, step 548 of the previous loop is executed.
Since the safe fall change flag is set to ``1'' in step 14, the determination result in step 54804 is +1 y
Switch to eSI+. Then, the following step 54818
~54824, the safe sensor 830 sets the safe sensor falling flag to If I 11 (step 54818) to remember that there is no safe ball within the safe sensor 830 (after the safe ball has passed). , when the value is '1'', the safe sensor rise flag indicating that the safe ball has reached the sensor is reset to II O''' (Step 54820), and then the safe fall change flag is set to II Q II. At the same time as resetting (step 34822), the safe high level flag is set to ll l II to remember that the output signal of the safe sensor 830 in this loop is at L level (step 54824), and this routine ends.

Thereafter, as long as the output signal of the safe sensor 830 is at the L level, steps 54802, 54804, and 548
06, 54808, and 54810 will be executed repeatedly, and at this time, the safe fall flag will be + 1 ++,
The safe rise flag is held at O'''.

On the other hand, the output signal of the safe sensor 830 changes from H level to L level.
If the output signal rises to the H level in the loop immediately after the level falls (step 54814 was executed in the previous loop and the safe falling change flag became 111++, and the current loop rose to the H level) case), the determination result in step 54802 is "Yes", the determination result in step 54830 is "No", and step 54
The determination result of 832 is determined as “Yes”,
At step 34850, a safe rise change flag is set to 111'' to remember that the output signal rose from the previous loop to the current loop, and at step 54
At step 852, the safe fall change flag set to "1'" during the previous loop is reset to "O++" and this routine ends.

As described above, unless the L level state is detected for a predetermined period of time or longer (at least while this interrupt processing is performed twice) after the output signal of the safe sensor 830 falls, the safe fall flag is set to '1'. The setting process (indicating that there is no safe bulb in the safe sensor 830) is not performed, and if noise occurs in the output signal of the safe sensor, the safe fall flag may be set by mistake. 1″
It is no longer set to .

FIG. 22 shows step S50 of the interrupt processing shown in FIG.
12 is a flowchart showing a subroutine of input processing of the replenishment sensor 211 performed in FIG.

As mentioned above, the replenishment sensor 211 is connected to the storage tank 201.
This is to detect the shortage of game balls (spare balls) in the tank 201, and the stored spare balls are detected by the replenishment sensor 2 in the tank 201.
It is configured so that it outputs an L level signal when it is up to the installation position 11 (5), and an H level signal when it is not.

Consider a state in which the metal plate is not filled with spare balls up to the sensor installation position in the tank 201 (insufficient state).

In this state, the power is turned on to the prize ball discharge control device 600,
When the routine starts, first, step 55002
It is determined whether the output signal of the sensor 211 is at the H level (replenishment sensor 8 force = "l'"). In this case, the determination result is "Yes" and the process proceeds to step 55004.

By the way, immediately after the MPU 620 is initialized, all flags are set to 'O', so steps 55004 to 55004-5
All the determination results in step 5010 are IINoI+, and in step 55012, the replenishment H level flag is set to I++ to remember that the output signal of the replenishment sensor was at H level in this loop, and this routine ends. Since the replenishment H level flag is set to "1" in the subsequent loop, steps 55002, 55004, 55006, 5500 are performed as long as the output signal remains at the H level.
8.55010 will be executed repeatedly.

After that, the storage tank 2 is filled with game balls (spare balls).
When the spare bulbs are filled up to the installation position of the replenishment sensor 211 in 01, the output signal of the replenishment sensor 211 changes to L level, and the determination result of step 550O2 becomes l Nor.
” and proceeds to step 55030 onwards.

When step 55030 is performed for the first time, the replenishment H level flag is l l 11 and all other flags are '0''.
The determination results of the next step 55032 are both 11NO! +
, the following step 55034 becomes "Yes", and steps 55036 and 55038 are executed.

In step 55036, in order to remember that the output signal of the replenishment sensor 211 changed from the H level to the L level (falling) from the previous loop to the current loop, the replenishment fall change flag is set to B, and the following step 55038
Now, the replenishment H level flag that was set to "l11" in the previous loop is reset (set to "Q++"), and this routine ends.

In the next loop, the output signal of the replenishment sensor 211 will continue to be L.
At the level, the replenishment fall change flag was set to '1' in step 55036 of the previous loop, so the determination result in step 55030 changes to "Yes".Then, in the following steps 55040 to 55046, the storage tank 201 The replenishment sensor falling flag is set to II II II (step 55040) to remember that the spare balls are filled up to the replenishment sensor 211 installation position within the sensor 211, and when the value is "1", the sensor 211 is installed. Set the replenishment sensor start-up flag (set to 0'' when this step is executed for the first time after initialization) indicating that there is no prize ball at the position to '0'' (step 55042), and then Reset the falling change flag to 'O'' (
At the same time as step 55044), the replenishment L level flag is set to "1" to remember that the output signal of the replenishment sensor 211 in this loop is at L level (step 55
046) End this routine.

Thereafter, as long as the output signal of the replenishment sensor 211 is at the L level, steps 55002, 55030.55Q3
2,55034,55048 will be executed repeatedly, and at this time, the replenishment sensor falling flag will be set to II I I
I, the replenishment sensor rise flag is held at ``0''.

On the other hand, if in the loop immediately after the output signal of the replenishment sensor 211 falls from the H level to the L level, the output signal rises to the H level (step 55036 was executed in the previous loop, and the replenishment fall change If the flag is “B” and the sensor output is H level in this loop), the determination result in step 55002 is “’Y”.
es, the determination result in step 55004 is ""No'
, the determination result in step 55006 is determined as r+yesn, and in step 35028, the replenishment rise change flag is set to '1'' to remember that the output signal rose from the previous loop to the current loop, and
In step 55029, the replenishment fall change flag set to "1" during the previous loop is returned to "OII", and this routine ends.

As a result, the replenishment fall flag is set to 1111+ (storage The process (indicating that the spare bulb is filled up to the sensor 211 set position in the tank 201) is not performed, and it is possible to deal with cases where noise occurs in the output signal of the replenishment sensor. There is.

Next, consider a case where the prize ball discharge control device 600 is powered on and this routine is started in a state where the reserve balls are filled up to the sensor 211 installation position in the storage tank 201.

First, in step 55002, the output signal of the sensor 211 is at H level (replenishment sensor output = II I 11 ).
In this case, the determination result is "
No'', and the process advances to step 55030.

Immediately after the MPU 620 is initialized, all flags are set to OII, so steps 55030 and 55032
, 55034, 55048 are all 'No'
Therefore, in step 55054, the replenishment L level flag is set to IIT'' to remember that the output signal of the replenishment sensor was at L level in this loop, and this routine ends.

In subsequent loops, the supply L level flag is set to 'B'.

As long as the output signal remains at L level, steps 55002, 55030°55032
, 55034, and 55048 are executed repeatedly.

Thereafter, when the installation position of the reserve supply sensor 211 in the tank 201 is no longer filled with the emptying of the prize balls, the output signal of the supply sensor 211 becomes H level, and the step 5
The determination result of 5002 is 'Yes' and the process goes to step 55.
Proceed to 004 onwards.

When step 55004 is performed for the first time, the supply L level flag is II I II and all other flags are It Q II, so step 550
04, the determination results of the next step 55006 are both 11
No”, the subsequent step 55008 becomes ly esTl, and step 55014 is executed.

In this step 55014, the replenishment rise change flag is set to II II II in order to remember that the output signal of the replenishment sensor 211 changed from L level to H level (rise) from the previous loop to the current loop. In the following step 55016, the replenishment L level flag, which had been set to "'1"' in step 55054 before the previous loop, is reset (set to "OII"), and this routine ends.

In the next loop, the output signal of the replenishment sensor 211 continues to be H.
At the level, the replenishment start-up change flag was set to "1 u" in step 55014 of the previous loop, so after the determination in step 55002 is performed, the determination result in step 55004 changes to "Yes".
In subsequent steps 55018 to 55024, the replenishment sensor 2
11, the replenishment sensor startup flag is set to "1'" to remember that there is no prize ball at the replenishment sensor 211 installation position in the storage tank 201 (step 55018).
At the same time, when the value is "1", a replenishment sensor fall flag indicating that there is a prize ball at the sensor installation position in the storage tank 201 (when this step is executed for the first time during initialization, it is set to "0"). II Q II 4: Configure (Step S 5020) and set (Step S 5
022), the replenishment H level flag is set to "'bi" to remember that the output signal of the replenishment sensor 211 in the current loop is at the H level (step 55024), and this routine ends.

Thereafter, as long as the output signal of the replenishment sensor 211 is at H level, the steps 55002, 55004, and 5500
6, 55008, and 55010 are repeatedly executed, and at this time, the replenishment start flag is held at "1" and the replenishment fall flag is held at "0".

On the other hand, if in the loop immediately after the output signal of the replenishment sensor 211 rises from the L level to the H level, the output signal falls to the L level (step 55014 was executed in the previous loop and the replenishment rise change If the flag is "BI" and the loop is at L level this time), the determination result in step 55002 is NO, and step 5503
The determination result of step 55032 is determined as "No", and the determination result of step 55032 is determined as IIYesI+.
In step 5050, the replenishment fall change flag is set to "1°" to remember that the output signal fell from the previous loop to the current loop, and in step 55052, the replenishment fall change flag set to "I II" during the previous loop is set. The upper change flag is returned to "0" and this routine ends.

As described above, unless the H level state is detected for a predetermined period of time or longer after the output signal of the replenishment sensor 211 rises (at least while this interrupt processing is performed twice), the replenishment start flag is set to "1". The setting process (indicating that there is no prize ball at the sensor 211 installation position in the storage tank 201) is not performed, so that it can be handled in cases where noise occurs in the output signal of the replenishment sensor. It has become.

The replenishment sensor rise flag and replenishment sensor fall flag that are set to "0" or "II" in this way are shown in the above-mentioned replenishment process (Fig. 16) executed in step S16 of the main routine (Fig. 14). Used in

FIG. 23 is a flowchart showing the input processing routine of the half-end sensor 221 performed in step S52 of the interrupt processing (FIG. 18).

The half-end sensor outputs a signal for setting the half-end sensor ball presence flag used in the discharge start process (FIG. 29) described later. The output signal is configured to be at H level (when more than the number of spare balls to be ejected for two prize balls is stored) and to be at L level when the number is less than the above number and is in an irregular state.

When this routine starts, it first starts at step 55200.
, the output of the half-way sensor is H level (half-way sensor output = I
I l”) is determined.

Let us consider a case where the spare balls have not been stored in the metal plate up to the halfway sensor installation position of the guide gutter 202, and the spare balls have been replenished and the sensor has reached the installation position.

If the spare ball has not reached the installation position, the determination result in step 55200 is "No".

At this time, all the determination flags have been reset to II Q II (step S4 in FIG.
), and the results of the determination in step 55204 (whether the half-sphere non-monitoring flag is "l'") are both 11NoI+,
Set the half-sphere non-monitoring flag to “l11” Step 5
Step 5206), set the hemispherical presence monitoring flag to "0" (Step 35208), and set the hemispherical no timer to a predetermined value (2).
sec) (step 55210) and ends this routine.

Here, the half-ball non-monitoring flag is used to determine whether or not a state in which the spare ball has not reached the installation position is detected (step 5).
5204), and the half-end ball presence monitoring flag is used to determine whether or not the state in which the spare balls have accumulated to the above-mentioned installation position has been detected twice in a row (step 55220). This is the flag that will be displayed.

Continuing in the next loop, if the spare balls have not accumulated to the above installation position, the determination results in steps 55200 and 55202 are both ``No'', and the subsequent determination result in step 55204 is ``1yesI+'', and step 55212 is performed.
is executed.

In this step 55212, it is further determined whether or not the ball-free timer has timed up, that is, after it is determined for the first time that the spare balls are not accumulated at the above-mentioned installation position (after the execution of steps 55206 to 55210 described above), a predetermined period of time ( 25ec
), and if the result of the determination is "No", the following steps 55214 and 55216 are skipped and this routine is ended. On the other hand, the step 55
If the determination result in step 212 is “Yes”, step 5
In step 5214, the half sensor ball missing flag is set to "1, 11" to indicate that the spare balls have not accumulated up to the sensor installation position of the guide gutter 202, and at the same time, in the next step 55
At step 216, the half sensor bulb presence flag (which is set to an initial value of "0" when this step is performed for the first time after initialization) is reset (set to "0"), and this routine ends.

In subsequent loops, unless the spare balls are accumulated up to the above installation position, the determination result in step 55200 is 11 No. II.
The determination result in step 55202 becomes 'Yes', and these steps are repeatedly executed.

From this state, when the game balls are supplied to the storage tank 201 and the spare balls accumulate up to the installation position of the half-end sensor 221 of the guide gutter 202, the determination result in step 55200 becomes "Yes".
becomes. In the subsequent step 55218, it is determined whether or not it is Pabi'.Since the half-odd sensor bulb presence flag is still set to the initial value II OII at this point, the result of this determination is IINoI+, and the determination result in the subsequent step 55220 (half-odd The result of whether the ball presence monitoring flag is "1" also becomes "No" by executing step 55208 described above, and the process proceeds to step 55222.

In step 55222, the hemispherical presence monitoring flag is set to “l I
In step 55224, the hemispherical non-monitoring flag is set to "'0", and the hemispherical presence timer is set to a predetermined value (25ec) (step 5522).
6) End this routine.

In the next loop, if the spare balls have accumulated up to the installation position of the half-end sensor, the determination result in step 55200 is "Yes", and the determination result in step 35218 is "N".

es (set to "BI" in step 55222 of the previous loop) and step 55228 is executed.

In this step 85228, it is further determined whether or not the ball presence timer has timed up, that is, after it is determined for the first time that the spare balls have accumulated up to the above installation position (step 5 described above).
After executing steps 5222 to 55226), it is determined whether a predetermined period of time (25 ec) has elapsed, and if the determination result is "No", the following steps 55230 and 55232 are skipped and this routine is ended. On the other hand, when the determination result is "Yes", that is, when the predetermined time has elapsed after the spare balls have accumulated to the sensor mounting position, in step 55230,
In order to show that the spare balls have accumulated up to the installation position of the half-end sensor 221, the half-end sensor ball present flag is set to 'l', and in the next step 55232, the half-end sensor ball missing flag is reset (set to "OII"). ) to end this routine.

In the subsequent loop, as long as the spare balls are stored up to the halfway sensor installation position in the guide gutter 202, step 55200 is performed.
The determination result of step 85218 is ``Yes'', and the determination result of step 85218 is 1lyes'', and these steps are repeatedly executed.

As described above, in the manual processing, in the loop immediately after the output signal of the odd sensor 221 changes from L level to H level (or from H level to L level), the output signal changes from L level to H level (or from H level to H level). Changes in L level) are only stored (setting the monitoring flag to 1411+), and the next loop is still at H level (or L level) and a predetermined time (2 sec) has elapsed since the above change. Only later is the final output value of this routine, that is, the half sensor bulb present flag, changed to "'1" (or the half sensor bulb absent flag, to "bi"). By adopting such a control procedure, even if the output signal level of an odd sensor changes instantaneously due to noise occurrence, the change will not be immediately judged as a normal change, and the noise occurrence etc. It is possible to prevent malfunction due to

FIG. 24 is a flowchart showing a subroutine of the input processing of the overflow detector 770 performed in step S54 of the interrupt processing (FIG. 18).

Overflow detector 770 performs step S of interrupt processing.
Firing motor control processing performed at 56 (Fig. 25),
This is to output a signal to determine the no overflow ball flag used in the discharge start process (Fig. 29), etc. described later, and indicates that some of the prize balls in the prize ball discharge gutter 751 have accumulated above the level. state, the output signal is H level,
It is configured so that it becomes L level when it is below a certain level.

When this routine starts, it first starts at step 55400.
The output of the detector is at H level (overflow output = “1”).
″) is determined.

When the prize ball changes from a state in which the prize ball has not reached the installation position of the overflow detector in the ball lead-out gutter 750 to a state in which the prize ball has been ejected and has reached the position of the detector 770 in the ball lead-out gutter 750 on the gold plate. think of.

In a state where the prize ball has not reached the position of the detector, the determination result in step 55400 becomes "NoI+".

At the beginning of this routine, all determination flags are 11.Q
It is reset to I+ (step S4 in FIG. 14).
Therefore, the determination in the following step 55402 (the no overflow ball flag is ii 1 n), and step 5540
4 determination (overflow bulb unmonitored flag is ul I
+ or) are both IINoI+, and the overflow ball non-monitoring flag is set to ``B'' in step 5540.
'6), set the overflow ball presence monitoring flag to "0" (step 35408), and set the overflow ball no timer to a predetermined value (25ec) (step 55).
410) End this routine.

Here, the overflow ball non-monitoring flag is a flag used to determine whether or not a state in which the prize ball has not reached the detector position has been detected two or more times in a row (control in step 55404); The overflow ball presence monitoring flag determines whether or not the prize ball reaching the detector position is detected two or more times in a row (step 5542).
This is a flag used to make a judgment of 0).

Continuing in the next loop, if the prize ball has not reached the above position, the determination results in steps 55400 and 55402 are both "No u", and the subsequent determination result in step 55404 is "Yes", and step S5412 is executed. Ru.

In step S5412, after it is determined for the first time whether or not the no-ball timer has timed up, that is, the prize ball has not reached the mounting position of the detector (step S5412 described above)
After executing 5406 to 55410] It is determined whether a predetermined time (2 seconds) has elapsed, and the determination result is llNo! When it is 1, the following steps 55414 and 55416 are skipped and this routine ends. On the other hand, the discrimination result is “Ye”.
s'', in step 55414, the no overflow ball flag is set to 1'' to indicate that the prize ball has not reached the detector position, and in the next step S5416, the overflow ball presence flag (this When the step is performed for the first time after initialization, the initial value it
(set to On) (set to 11011) and ends this routine.

In the subsequent loop, unless the prize ball has reached the position of the detector, the determination result in step 55400 is "No", the determination result in step 35402 is "Yes", and these steps are repeatedly executed.

Next, the prize balls ejected from this state accumulate and enter the detector 7.
Consider the case where the position reaches 70. At this time, the determination result in step 55400 becomes "Yes," and in the following step 35418, it is determined whether or not the overflow ball presence flag is "1".This overflow ball presence flag was set to "0" by the previous loop. Therefore, the result of this determination is "No" (step 55416).

In the following step 55420, it is determined whether the overflow ball presence monitoring flag is "1", but this overflow ball presence monitoring flag has also been set to II Q II by the previous loop.
(step 55408), the result of this determination is "INO+1," and the overflow bulb monitoring flag is set to II II II (step 55422), and the overflow bulb non-monitoring flag is set to i.
IOII is set (step 55424), and the overflow timer is set to a predetermined value (25ec) (step 55426), and this routine ends.

Continuing in the next loop, when the prize ball reaches the position of the detector 770, the determination result in step 55400 is "Yes" and the determination result in step S5418 is "NO."
”, the determination result of the subsequent step 354.20 is 'Ye.
s” and step 85428 is executed.

This step 55428 further determines whether or not the ball presence timer has timed up, that is, after it is determined for the first time that the prize ball has reached the above position (steps 55422 to 55428 described above).
After executing step 55426), it is determined whether a predetermined time (2 seconds) has elapsed, and if the determination result is 1N0T'', the following steps 55430 and 55432 are skipped and this routine is ended.

On the other hand, if the determination result is "Yes", step 55
At step 430, the overflow ball presence flag is set to "1" to indicate that the prize ball has reached the detector position, and at the next step 55432, the overflow ball no flag is reset (set to 'O''). ) to end this routine.

In the subsequent loop, as long as the prize ball reaches the position of the detector 770 in the prize ball discharge gutter 751, step 55400 is performed.
The determination result of step 85418 is "'Yes," and the determination result of step 85418 is "Yes," and these steps are repeatedly executed.

As described above, in the manual processing, as in the case of the safe sensor, in the loop immediately after the output signal changes from the L level to the H level (or from the H level to the L level), the output signal changes from the L level to the H level (or from the H level to the L level). The change from H level to L level) is stored only (the monitoring flag is set to "1"), and the next loop will still be at H level (or L level).
Furthermore, a predetermined period of time (25 ec
) has elapsed, the overflow bulb presence flag, which is the final product quality value of this routine, is changed to 1''' (or the overflow bulb no flag is changed to 1''). This control procedure is adopted. By doing so, even if the overflow output signal level changes instantaneously due to noise generation, etc., the change will not be immediately judged as a normal change, and malfunctions due to the noise generation etc. can be prevented. It is now possible to do so.

FIG. 25 is a flowchart showing a subroutine of firing motor control processing performed in step S56 of the interrupt processing (FIG. 18).

When this routine starts, it first starts at step 55600.
The touch switch 10 provided on the batted ball launcher 150 in
It is determined whether or not 5a is 110 N II, that is, whether or not the player is in control of the operation dial 105, and in the next step 55602, it is determined whether or not the above-mentioned no overflow ball flag is '1''. That is, it is determined whether the ejected prize ball has not yet reached the installation position of the detector 770 in the prize ball ejection gutter 751. When the determination results in both of these two steps are 'Yes', the firing motor 151
In order to operate the ball launcher 150, the motor control relay (not shown) is turned ON (step 55604).
), this routine ends.

On the other hand, when either of the determination results in steps 55600 and 55602 (7) becomes =NO++, the motor control relay is turned "OFF" (step 556).
06), this routine ends.

FIG. 26 is a flowchart of the input processing routine for the memory clear switch 614 performed in step S58 of the interrupt processing in FIG.
4, as described above, is the operation by which the staff at the game parlor sets the safe memory value to 1 noa ("t"), i.e., the clear switch 6 installed in the prize ball lotto output device 160f).
The output signal is configured so that when 14 is pressed by the staff force, the output signal is at H level, and when it is not pressed for 6 seconds, it is at 2L level.

Therefore, in this flow, when the output signal of the switch/edge 614 changes from L level to H level, the memory clear flag (to be described later) is set to the safe memory value, and the staff at the game parlor sets the safe memory value. It is designed to indicate that an operation has been performed to clear the ball.Then, the prize ball discharge control device
The above-mentioned memory value clearing process (FIG. 15) is performed based on the memory clearing flag set in the memory.

When this routine is started, it is first determined in step 55802 whether the clear change flag is "'1", and further in step 55804 it is determined whether the clear high level flag is "1".

By the way, as mentioned above, all the discrimination flags are set to 110++ in the main routine (step S4 in FIG. 17) immediately after the power in the prize ball ejection control device 600 is turned on, so the step 55802 .55804
The determination results of both are LL NOI+, and step 3
At 5806, the output signal of the memory clear switch goes to L level (
It is determined whether or not the memory clear switch output = "0°".

Let us consider the case where the memory clear switch installed in the prize ball discharge control device is pressed by an attendant at a game parlor from a state where it has not been pressed yet.

When the memory clear switch is not pressed, the output signal of the switch 614 remains at the L level, so the determination result in step 55806 is 11 Y eS'+, and the process proceeds to step 35808, where the clear high level flag is set to l. ``'' and end this routine.

When the signal from the memory clear switch still holds the L level in the subsequent loop, the clear high level flag is set to '''l++, so the determination result in step 55804 changes to YesII, and step Proceeding to 35810, the output signal of the memory clear switch in this loop is H level (memory clear switch output = “
1'"). At this time (when the output signal of the memory clear switch is held at L level), the result of this determination is 11 N OI+, and this routine ends as it is. Therefore, as long as the output signal of the memory clear switch maintains the L level, step 55802
．． 55804 and 55810 will be repeatedly executed.

When the memory clear switch is pressed from this state and the signal from the switch changes from L level to H level, the determination result in step S5810 changes to II y eSu, and in the following step 35812, the memory clear switch 614 is activated in this loop. In order to remember that the output signal of has changed from L level to H level, the clear change flag is set to “l ++
Then, in step 55814, the clear high level flag is reset to II O++, and this routine ends.

When the output signal is at H level in this loop as well as in the previous loop, the clear change flag is set to 1'' by the processing in step 35812 of the previous loop, so the determination result in step 35802 is l Y eSTT.
Then, the process proceeds to step 35816, where it is determined whether the output signal of the memory clear switch in the current loop is at H level (memory clear switch output = "1"').

If the determination result is "Yes", that is, the output signal is at H level in the current loop as well as in the previous loop, the clear change flag is reset to O'' in the following step 55818, and the memory clear flag is further transferred to step 55820. Set "Pavi" and end this routine.

In the subsequent loop, if the output signal of the memory clear switch is still at H level, the determination result of step 35802 is '
The state changes to ``No''+ (the clear change flag has been reset to ``O''), and then the determination results in steps 55804 and 55806 both become ``No'', and steps 55802, 55804, and 55806 are repeated thereafter. It will be executed.

On the other hand, the output signal of the memory clear switch changes from L level to H level.
When the output signal of the memory clear switch changes to the L level again in the loop immediately after the change to the L level (immediately after the steps 55812 and S5814 are executed), the determination result of the step 55816 is "NoI".
becomes + and the step 55818 (clear change -y-
y ``o''), step 3 without executing step 55820 (memory clear flag=''1'')
At step 5822, the clear level flag is set to "bi", and the clear change flag is reset to 11011 (step 55824), and this routine ends.

After the output signal of the memory clear switch changes from the L level to the H level, the memory clear flag is set only when the output signal remains at the H level while at least two processing loops are executed. Since the flag is set to '1', the memory clear flag will not be erroneously set to '1' even if noise or the like occurs and the output signal temporarily rises to the F (level).

FIG. 27 is a flowchart of the recovery switch 780 input processing routine performed in step S58 of the interrupt processing in FIG.

As mentioned above, the recovery switch 780 is demagnetized (turned OFF) when a fraud occurs and the first and second prize ball deriving channels 710 are turned off.
, 710 is energized again to enable the ejection of the prize ball.When the attendant presses the recovery switch, the output signal is H level, otherwise it is L level. It is configured as follows.

Therefore, in this flow, when the output signal from the switch 780 changes from the L level to the H level, the game parlor staff energizes the lock solenoid 721 (ON ) to indicate that the operation was performed to and,
The prize ball discharge control device performs the above-mentioned error recovery process (FIG. 17) based on the recovery ON flag set to "1".

When this routine is started, first, in step 56000, it is determined whether the recovery change flag is "BI'", and further, in step 56002, it is determined whether the recovery L level flag is "1".

By the way, as mentioned above, all the discrimination flags are set to "0" in the main routine (step S4 in FIG. 14) immediately after the power in the prize ball ejection control device 600 is turned on, so the step The discrimination results of 56000 and 56002 are both l'N oI+, and step 56004
It is determined whether the output signal of the recovery switch is at L level (recovery switch output="o").

Let us consider a case where the recovery switch 780 installed on the back mechanism panel 200 has not been pressed yet, and a case where it is subsequently pressed by an attendant at the game parlor.

When the recovery switch is not pressed, the switch 78
The output signal of 0 remains at L level, so the determination result in step 56004 is 'YesI+', and the process proceeds to step 56006, where recovery is performed to store that the output level of the recovery switch in this loop was L level. The L level flag is set to 1111+, and further step 560
At 08, reset the recovery ON flag to °'0''' (
(It has already been reset to 110'' immediately after the power is turned on) This routine ends.

In the subsequent loop, the signal from the recovery switch is still low.
When the level is maintained, the recovery L level flag is set to '1'', so the step 5600
The determination result of step 2 changes to 11 Yes esII, and step 5
Proceeding to 6010, it is determined whether the output signal of the recovery switch in the current loop is at H level (recovery switch output = "1"').

At this time (when the output signal of the recovery switch maintains the L level), the determination result is If N OIt.
This routine ends immediately. Therefore, as long as the output signal of the recovery switch maintains the L level.

Steps 56000, 56002, and 56010 will be executed repeatedly.

When the recovery switch 280 is pressed from this state and the signal from the switch changes from L level to H level, the determination result in step 36010 changes to 11 y esI+, and in the subsequent step 56012, the recovery switch 780 is activated in this loop. Set the recovery change flag to "F" to remember that the output signal has changed from L level to H level,
Next, in step 56014, the recovery L level flag is reset to O''' to indicate that the output of the recovery switch is no longer at L level, and this routine ends.

When the output signal is at H level in this loop as well as in the previous loop, the recovery change flag is set to II II II by the processing in step 56012, so the determination result in step 56000 changes to 'Yes', and the process goes to step 56016. Next, it is determined whether the output signal of the recovery switch in this loop is at H level (recovery switch output - "'1").At this time, the determination result is "Yes".
”, and in the subsequent step 56018, the recovery change flag is reset to II OII, and further in step 5602
0, the recovery ON flag is set to 1'' and this routine ends.

In the subsequent loop, when the output signal of the recovery switch is still at H level, the determination result in step 56000 is lN
Or+ (recovery change flag is set in step 5601)
8), then step 56002. Both of the determination results in step 56004 are II Not'', and henceforth step 5600
0, 56002, and 56004 will be executed repeatedly.

On the other hand, immediately after the output signal of the recovery switch changes from L level to H level (step 56012, step 5
Immediately after step 6014 is executed), when the output signal of the recovery switch changes to L level again, the determination result of step 56016 becomes "No", and step 56018 (recovery change flag -'0''' ) and step 56020 (recovery ON flag = II
Step 5602 without performing
In step 2, the recovery L level flag is set to ti I II to remember that the Roka level in this loop is L level, and the recovery change flag is further set to 11011 (step 56024), and this routine ends. do.

After the output signal of the recovery switch changes from the L level to the H level, the recovery ON flag is set only when the output signal maintains the H level for at least two processing loops. Since the recovery ON flag is set to ``1'', even if noise or the like occurs and the output signal temporarily rises to the H level, the recovery ON flag will not be erroneously set to 1''.

FIG. 28 is a flowchart showing a subroutine of safe ball determination processing performed in step S62 of the interrupt processing in FIG. 18.

This subroutine determines the pulse width of the output signal of the safe sensor (the time interval during which the H level is maintained) based on the safe rising flag and safe falling flag, the values of which are determined in the safe sensor input processing (Fig. 21) described above. ), and the time interval at which the H level is maintained is within a predetermined range (a range determined experimentally depending on the shape of the winning ball outlet gutter through which the safe balls in the pachinko machine flow (for example, 4 m5ec).
~50m5ec)), the output signal is determined to represent the passage of the safe sphere, and the safe memory value is added by 1; on the other hand, if the time interval is abnormally long (for example, 100m5ec or more) and the sensor When a short circuit of 830 is detected, an error process is performed and the staff at the game parlor is notified of this.

When this routine is started, first in step 56202 it is determined whether the safe error flag is "1". As will be described in detail later, this safe error flag indicates that the output signal of the safe sensor 830 remains at the H level for a predetermined period of time (1
00m5ec) or more, or sensor 8
When 30 short circuits are detected, step 562 will be described later.
26, the value is set to 1111+.

When this routine is started for the first time, the flag is “′
Since the determination result in step 56202 is "No", it is determined in step 56204 whether or not the safe sensor 830 is short-circuited. The determination is made based on the output signal appearing at the high-strength terminal C of the short calibration section 830c.In other words, the output level at this 0 point is L.
When the level is high, it is determined that the safe sensor 830 is not short-circuited, and conversely, when the level is H, it is determined that the safe sensor 830 is short-circuited.

When a short circuit is detected based on the output level of the high-strength terminal C (the determination result in step 56204 is 11 y es
I+), steps 56226 to 56 described below.
A series of error processing according to H.234 is performed.

On the other hand, the determination result of step 56204 is II N
If oll, the process proceeds to step 56206 and subsequent steps to monitor the waveform of the output signal (pulse width check) using the safe rising flag and safe falling flag described above.

First, in step 56206, it is determined whether the pulse width check flag is "1". This pulse width check flag is set to “I II” when the output signal of the safe sensor rises (safe rise flag = II I 11).
(step 56210 described below), and the value of this flag remains “ while the pulse width is being measured.
I II is held.

Consider a case where a winning game ball (safe ball) reaches the safe sensor from a state where it has not yet reached the safe sensor 830 and escapes from the multi-nuclear safe sensor 830.

First, when the safe sphere has not reached the sensor, the pulse width check flag is II OII (this flag is set to II I I only by executing step 56210).
(set to I), the process proceeds to step 56208, where it is determined whether or not the above-mentioned safe rise flag is set to 1''.

If the safe ball has not yet reached the inside of the sensor, the result of this determination is rNO1'', and the routine ends. Therefore, only steps 56202 to 56208 are repeatedly executed until the safe ball reaches inside the sensor. That will happen.

After that, when the safe ball reaches inside the sensor (when the safe sensor output rises to "1"), the safe rise flag is set to "1" by the above-mentioned safe sensor input process (Fig. 21), and the safe rise flag is set to "1" in step 56208. The discrimination result is “Y e
Then, in step 56210, the pulse width check flag is set to NIII, and in step 56212, the pulse width timer starts counting from "0", and then this routine ends.

The output signal of this pulse width timer is rising (H
It measures the time interval (holding the level), and the measured value is used in steps 56216, 56220,
6222 is used for determination.

When moving to the next loop, the determination result in step 56206 changes to "Yes"', and the process proceeds to step 56214, where it is determined whether or not the safe fall flag is 1". In this loop, the safe sensor still remains active. Output signal is H
When the level is maintained (when the safe ball is moving within the sensor), the safe fall flag is set to “OI”.
I (discrimination result is l N oll ), step 5
At 6216, it is determined whether the count value of the pulse width timer at this point has exceeded a predetermined value (100 m5ec).

When the determination in this step is executed for the first time after the output signal of the safe sensor 830 rises, the determination result is II.
The result is NOI+, and this routine ends immediately.

After that, step 5 until the safe ball escapes from inside the sensor.
6202, 56204, 56206 and step 562
14,56216 will be repeated.

From this state, when the safe ball escapes from inside the sensor (safe sensor "O") and the safe fall flag is set to II I 11 by the above-mentioned safe sensor input process, the determination result of step 56214 is In step 56218, the pulse width check flag is set to indicate that the pulse width counting is finished.
It is reset to On and the process proceeds to steps 56220 and 56222. In steps 56220 and 56222, the count value of the pulse width timer at this point (the output signal is
A determination is made as to whether or not the period during which the level was maintained is within a predetermined range.

That is, in step 56220, it is determined whether the count value is less than the minimum time required for the safe ball to pass through the safe sensor 830 (first predetermined value; for example, 4 m5ec), and in step 56222, the above-mentioned It is determined whether the count value is less than or equal to the maximum time required for the safe ball to pass through the sensor (a second predetermined value; for example, 50 m5ec).

When the safe ball passes through the safe sensor 830,
The determination result in the step 56220 should be "No" and the determination result in the step 56222 should be "Yes". At this time, the process advances to step S6224, and 1 is added to the safe memory value at this point. to end this routine.

On the other hand, the determination result in step 56220 is “Yes”.
In other words, the time interval (timer count value) from the time when the output signal of the safe sensor is determined to have risen to the time when it has been determined that it has fallen (while the H level is maintained)
If it is less than the above-mentioned minimum value (4 msec), it is determined that the rise and fall of the signal are due to noise generation, and this routine is ended without adding the safe storage value. At this time, since the pulse width check flag has already been reset to it On in step 56218, the pulse width check will be repeated from the beginning after the sensor output signal rises again in the next and subsequent loops.

Further, if the determination result in step 56222 is NO, that is, the time interval (timer count value) from the time when the output signal of the safe sensor is determined to have risen to the time when it has been determined that it has fallen exceeds the maximum value (50m5ec). In this case, the rising and falling values are assumed to mean that the safe sensor has mistakenly determined that the foreign object that has entered the sensor is a safe ball, and this routine is terminated without adding the safe memory value. . At this time, since the pulse width check flag has already been reset to 'O' in step 56218, the pulse width check will be repeated from the beginning after the sensor output signal rises again in the next and subsequent loops.

On the other hand, in this routine, after the output signal of the safe sensor rises, a predetermined time (third predetermined value; 100 m5ec)
If the output signal still does not fall even though the period has passed (the determination result in step 56216 is ly eS+
(+) A short circuit is detected, either because the safe sensor itself has malfunctioned, or because the player has intentionally inserted a foreign object (such as a piano wire) into the sensor, causing an illegal pulse. (The determination result in step 56204 is “Y”)
eS''], error handling from step 56226 onwards is performed.

In this error processing, first, in step 56226, the safe error flag is set to "1" to remember that the error processing has started, and in step 56228, the motor control relay is turned off (OFF) to prohibit firing of game balls. , In step 56230, the safe ball flow prevention solenoid is demagnetized (OFF) L in order to prevent the outflow of safe balls that have won at that point and have not yet been detected by the safe sensor 830.
Next, the failure indicator lamp 42 of the information display device (Fig. 4)
5c, an error is displayed (step 5623)
2) Generate an error sound from the speaker 689 (step 56234), and end this routine.

Determination of step 56216 described above or step 562
Once it is determined that an error has occurred through the determination in step 04 (the safe error flag is set to II II II), in the next and subsequent loops, the determination result in step 56202 becomes "Yes" and the step 56232 is performed.
(Error display) and 56234 (Error sound generation) will be executed.

Error handling that continues in this way is carried out in the main routine (
In the error recovery process (FIG. 17) performed in step S19 of FIG. 14), the error is canceled only based on the output signal of the recovery switch (by the recovery ON flag).

FIG. 29 is a flowchart showing a subroutine of the discharge start process executed in step S22 of the main routine (FIG. 14) of the prize ball discharge control device described above.

This subroutine sets up two rows of the predetermined number of prize balls (preset number of prize balls) when shipping a predetermined number of prize balls once for one winning ball (safe ball). The first and second prize ball guide channels 710, 710 (Fig. 4,
In addition to determining in advance how many discharges are to be discharged from one side of Figure 6) and how many from the other side, the discharge solenoid 1 and/or discharge solenoid 2 is energized (ON) L to follow the above-mentioned manner. This is to start discharging the prize balls.

When this routine is started, first, in step 5102, it is determined whether the half-end sensor bulb presence flag set in the above-mentioned half-end sensor input process (FIG. 23) is "'1", that is, whether the guide gutter 202 It is determined whether or not there are spare balls accumulated at the half-end sensor installation position.

Subsequently, in step 5104, it is determined whether the no overflow ball flag set in the above-described overflow detection input process (FIG. 24) is II II II, that is, if the ejected prize ball overflows in the prize ball discharge gutter 751. It is determined whether the detector 770 installation position has not been reached.

If either of the determination results in steps 5102 and 5104 is INOI+, the subsequent step 510
Steps 6 to 5150 are skipped and the routine ends. On the other hand, step 5102 and step 51
If both of the determination results in step 04 are IfYes++, the processing from step 5106 onwards is executed.

In step 5106, the number of prize balls pre-stored in the prize ball setting device 530 (see FIG. 13) connected to the prize ball discharge control device 600 is set in the discharge register O, and in step 3108, the number of prize balls set in the prize ball setting device 530 (see FIG. 13) is set in the discharge register O. It is determined in the following step S110 whether the value of the discharge register 0 is "8" or less.

If the determination result in the step 5108 is "Yes", that is, the value of the discharge register O is "1", the one discharge flag is set to "'bi" (step 5112), and the alternate discharge flag is set to "'O" (step 5l12). 5114), and further sets a one-piece discharge timer to a predetermined value (step 5116) to be used in the one-piece discharge process (FIG. 33) to be described later, and performs the inversion flag process of step 5122.

Here, the single discharge flag and alternate discharge flag mentioned above are:
The mode of prize ball ejection in the ejection process (Fig. 32) that is performed subsequent to this routine can be explained in the following three modes (one type in which only one game ball is ejected by activating either one of the ejection solenoids 1 and 2). Discharge process: Alternate discharge process in which discharge solenoids 1 and 2 are operated alternately to discharge game balls; discharge solenoid 1.

2 is activated simultaneously to discharge the game balls (combined discharge process)
This is a discrimination flag used when selecting from the following. When the one-piece discharge flag is set to it 1 u, one-piece discharge processing (when the number of prize balls set is 1) is performed, and the alternate discharge flag is set to 'l''. When set, alternate ejection processing (when the number of prize balls set is 2 to 8) is performed when both flags are set.
When set to +, the combined discharge process (the set number of prize balls is 9 to 15) is performed.

Returning to FIG. 29, the determination result in step 3108 is “
'No, the determination result in step Sl 10 is "Y".
es, that is, when the value of the discharge discharge register O is a value between "2" and "8", one discharge flag is set to "
The alternate discharge flag is set to '0'' (step 5118), the alternate discharge flag is set to II II (step 5120), and the inversion flag process of step 5122 is performed.

This reversal flag processing is the ejection processing of one prize ball,
Or when carrying out an alternate discharge process, the discharge solenoid 1 of the first prize ball discharge device 740 and the second prize ball discharge device 740
The value of the "reversal flag" provided to alternately operate the discharge solenoid 2 is alternately reversed each time the solenoid is operated, and as shown in Fig. 30, at the start of this process, When the inversion flag is IJ++ (corresponding to discharge solenoid 2) (the determination result in step 58001 is "Yes"), it is inverted to "ON" (step 580
02), on the other hand, when the reversal flag is 11011 (corresponding to discharge solenoid l) (the determination result in step 58001 is "No"), it is reversed to '1' (step 58
003).

When this reversal flag processing (step 5L22) is completed, it is determined in step 5124 whether or not the reversal flag is 0''.The result of this determination is II Y eSI+
At this time, the ejection solenoid 1 is energized (ON) L (
Step 5126), On the other hand, when the determination result in step 5124 is llN0, the second prize ball ejecting device 740
The ejection solenoid 2 is energized (ON) to eject the prize balls (step 5128), and the process proceeds to step 5144 and subsequent steps, respectively, which will be described later.

Further, when the determination results in steps 5108 and 5IIO are both "'N0In," that is, when the number of prize balls discharged is 9 or more, after performing the discharge number division process (FIG. 31) described later (step 5130), 1 Set the individual discharge flag to 0'' (Step 5132), set the alternate discharge flag to 0'' (Step 5134), and set the values of the discharge 1 end flag and discharge 2 end flag used in the combined discharge process described later to 110. ``'' is reset (steps 5136 and 3138), and both discharge solenoid 1 and discharge solenoid 2 are excited (ON) (steps 5140 and 5142), and the process proceeds to steps 5144 and thereafter.

In step 5144, a discharge weight flag, which is set to 'l'' when a predetermined number of prize balls have been discharged in a discharge process to be described later, is reset to 110''. In the next step 5146, the above-mentioned processing number (processing number) is set to ii 2 u, and in step 5148, three processes (single discharge process, alternate discharge process) performed in the discharge process (FIG. 32) are performed.

The discharge end flag, which is set to ``1'' at the end of each process (combined discharge process), is reset to ``0'', and the safe lamp is turned on (ON) in step 5150, after which this routine ends.

FIG. 31 shows step 51 of the discharge start process (FIG. 29).
30 is a flowchart showing a subroutine of the discharge number division process executed at step 30.

This routine is executed when the prize balls are discharged in the combined discharge process described later (the set number of prize balls (value of the discharge register O) is 9.
This process is performed only when the number is 15 or less. This is because in the combined discharge process, the discharge solenoids 1 and 2 are operated simultaneously in one control loop, so the value stored in the discharge register O in advance is divided into two and the values are stored in the two discharge registers 1 and 2, respectively. It is stored separately. The discharge solenoids 1 and 2 are operated independently according to the values of these two discharge registers 1.2.

When this routine is started, steps 3152 to 516

Then, the determination result in step 5152 is 11yes.
+'', the value of the discharge register 1 is set to "5" in step 5164, and the value of the discharge register 2 is set to "4" in step 5166, and this routine ends.

Thereafter, when the determination result of step 5154 is "Yes", the values of discharge register 1 and 2 are set to [5" (steps 3168 and 5170)), and when the determination result of step 5156 is "1cyeS", the values of discharge register 1 and 2 are set to [5"). Set the value to "6" (step S172
) and set the value of the discharge register 2 to 115 TI (step 5174), and when the determination result of step 5158 is "Yes", set the values of the discharge registers 1 and 2 to "6" (step 5176, step 3178).

When the determination result of step 2 is "Yes", the discharge register 1.
2 are both set to r7J (steps 3184 and 5186), and this routine ends.

On the other hand, when all of the determination results from step 8152 to step 5162 are "'NOI+", the value of discharge register 1 is set to "'8" (step 5188), and the value of discharge register 2 is set to "7". (Step 5

FIG. 32 shows the MPU 62 on the prize ball discharge control device side mentioned above.
In the main routine (Figure 14) performed at 0,
12 is a flowchart showing a subroutine of a discharge process executed when the process number is II 2 II.

When this routine is started, first, in step 5202, it is determined whether the discharge weight flag is "1''. This discharge weight flag is set in step 5222 described later.
It is set to 111 IT in the above-mentioned discharge start process and is reset to 0''' in the above-mentioned discharge start process, and when the value is "I II", a predetermined number of prizes (prize ball discharge number) corresponding to one safe ball This indicates that the ball has been ejected.

When this discrimination result is II N oI+, +)li
In the above-mentioned discharge start process (Fig. 29), the 1-piece discharge flag whose value is set based on the set number of prize balls is II I II
(Step 5204), and whether or not the alternate discharge flag whose value is similarly set according to the set number of prize balls is "1" (Step 5206) are determined.

When the determination result in step 5204 is 'Yes', that is, the set number of prize balls (discharge register O) is '1', the process proceeds to step 5208, and the prize ball is dispensed by one-piece discharging process (FIG. 33), which will be described in detail later. After discharging, the process proceeds to step 5218 and subsequent steps.

The determination result in step 5204 is 'N'.

When the determination result in step 5206 is “Yes”,
In other words, the set number of prize balls (value of discharge register O) is r2J or more.
8'' or less, the process proceeds to step 5210, and after the prize balls are ejected by an alternate ejection process (FIG. 33), which will be described in detail later, the process proceeds to step 5218 and subsequent steps.

When the determination results in step 5204 and step 3206 are both “No,” that is, the set number of prize balls (value of ejection register O) is “9” or more, the process proceeds to step 5212, and the combined ejection process (35th After discharging the prize balls as shown in FIG.

In step 5218, it is determined whether or not the ejection of a predetermined number (set number of prize balls) corresponding to one winning ball has been completed (whether or not the ejection completion flag is II I II); Step 5220 continues when the result is 11N01, that is, when it is determined that the ejection of a predetermined number (set number of prize balls) corresponding to one winning ball has not been completed yet.
This routine is ended by skipping step 5226.

On the other hand, the determination result in step 5218 is 1lyes''
In this case, the value of the "safe memory value" which is added by 1 each time a winning ball is detected by the safe sensor is subtracted by 1 (step 5220), the ejection weight flag is set to '1' (step 5222), and the ejection is performed. The wait timer is set to a predetermined time (for example, 400 m5ec) (step 5224), the safe lamp is turned off (step 5226), and this routine ends.

In the loop after the determination result in step 5218 changes to "Yes", the determination result in step 5202 changes to "Y".
es'', and step S214 is executed. In this step 5214, it is determined whether or not the ejection wait timer has timed up. If the determination result is 'No', that is, after the ejection of a predetermined number of prize balls is completed, the ejection wait timer is If the time has not yet elapsed, this routine is immediately terminated, and only steps 5202 and 5214 are repeatedly executed until the predetermined time has elapsed.When the predetermined time has elapsed (the determination result of step 5214 is
(Yes'''), the process proceeds to step 5216, sets the processing number (processing number) to PaO''', and ends this routine.

In this way, when the ejection processing of a predetermined number of prize balls corresponding to one winning ball is completed (during this time, the value of the processing number is held at II 2 II), the processing number is set to "'O". By resetting to ``, in the main routine from the next time onwards, the prize balls will be ejected the number of times corresponding to the number of ``safe memory values'' after being subtracted by l in step 5220 (the prize balls will be ejected for the set number of prize balls). (ejection of prize balls) will be executed repeatedly from the beginning.

FIG. 33 is a flowchart showing a subroutine of the one-piece discharge process performed in step 5208 of the above-described discharge process (FIG. 32).

As mentioned above, this routine is a process that is performed only when the number of prize balls to be ejected (set number of prize balls) is "1".

When this routine is started, it is determined in step 5232 whether or not the single discharge timer, which was set to a predetermined value in step 5116 of the discharge start process (FIG. 29), has timed out.

This one-piece ejection timer operates after activating the ejection solenoid 1 or 2, the first and second flow prevention parts 745 and 745 that have entered into the first and second prize ball derivation troughs 710 and 710.
(See Figure 7), but actually the above-mentioned lead-out gutter 710, 710
This is set to the time (approximately 35 m5ec) from when the prize ball escapes from the ball to when only one prize ball falls. Therefore,
When the one piece discharge timer has not timed up yet (
When the determination result is "No"), this routine is ended by skipping the following steps 5234 to 5240, and when the time is up (the determination result is "'Yes'")
Then, it is determined that one piece has been discharged and the process proceeds to step 5234.

In step 5234, the reversal flag at this point is '1'.
”, and the determination result is &NoI+
At this time, the discharge solenoid 1 that was energized in step 5126 of the discharge start process (FIG. 28) is demagnetized (OF).
F)L (Step 5236) When "Yes", the discharge solenoid 2, which was also excited in Step 5L28 of the discharge start process, is demagnetized (OFF) (Step 523
8) Proceed to step 5240 and set the discharge end flag to "l" to indicate that the prize balls have been discharged through this process.
, and end this routine.

Figure 34 shows step 5 of the discharge process (Figure 32) described above.
3 is a flowchart showing a subroutine of alternate discharge processing performed in step 210.

As mentioned above, this routine is a process that is performed when the number of prize balls to be ejected (preset number of prize balls) is between "2" and "8", and in this routine, the first and second prizes described above are The prize balls are ejected by alternately using the ball ejecting devices 740, 740.

When this routine starts, first, the discharge start process (second
The reversal flag set in step 5122 in Figure 9) is 0.

When the determination result is "Yes"', the first prize ball ejecting device 740 performs the prize ball ejection process (step 8254).
~5264) is performed, and on the other hand, the discrimination result is 11 No
When the result is N, the second prize ball ejecting device 740 performs the prize ball ejecting process (steps 5266 to 5274, 5264).

First, in step 5254, it is determined whether or not the discharge sensor 1 rise flag is P1'''.The result of this determination is
I N on, that is, after the ejection solenoid 1 is energized (ON) in step 5126 of the above-mentioned ejection start process (FIG. 29), if the ejection sensor 1 does not yet detect the ejection of the prize ball, the subsequent steps 5256 and 5256 are performed. Skip step 5264 and end this routine.

On the other hand, the determination result of this step 5254 is “YesI+
At this time, 1 is subtracted from the value of the discharge register O at this point in step S256), and the discharge sensor 1 start-up flag is reset to it On (step S3258).
), proceed to step 5260.

In step 5260, it is determined whether the subtracted value is "1" or not, and this result is discharged from the first prize ball discharge device by energizing (ON) the discharge solenoid 1, Further, when it is determined that the number of prize balls detected by the discharge sensor 1 has not reached the "set number of prize balls - 1", the following steps 5262 and 8264 are skipped, and this routine is ended.

On the other hand, the determination result in step 5260 is 1lyes.
That is, when the ejection of prize balls is started by the excitation (ON) of the ejection solenoid 1 in the above-mentioned ejection start process, and the ejection sensor 1 detects the number of prize balls equal to "the set number of prize balls - 1", the above-mentioned process is performed. It is assumed that the ejection of the set number of prize balls has been completed, and the ejection solenoid 1 is demagnetized (OFF) L in step 5262, followed by step 82.
At step 64, the discharge end flag is set to °'1'', and this routine ends.

By the way, as mentioned above, when the discharge sensor 1 detects the number of prize balls equal to "preset number of prize balls - 1", the reason why all the prize balls equal to "preset number of prize balls" are considered to have been ejected is as follows. Due to reasons. That is, step 5126 of the discharge start process
Immediately before exhaust solenoid 1 is energized (ON) at
Normally, as shown in FIG. 7, the second prize ball B1 from the bottom is located within the discharge sensor 1 (at this time, the output level is H level). Thereafter, when the third prize ball B in FIG. 10 reaches the inside of the ejection sensor 1 by excitation of the ejection solenoid 1, the sensor detects that one prize ball has been ejected. For this reason, for example, if the discharge solenoid 1 is demagnetized immediately after the sensor detects one prize ball (the prize ball B5 passes the sensor and the flow prevention member 745
), two prize balls B,
B.

will be discharged to the ball outlet gutter 750 side. Therefore, in the alternate discharge process and the combined discharge process described below, the number F is one less than the number of discharged (set number of prize balls) - 1
If the ejection process is performed by counting the rising edge of the ejection sensor by '', the set number of prize balls will be ejected.

Returning to FIG. 34, the determination result in step 5252 is 1.
1 NO1, that is, in the process performed when the reversal flag is o l u, it is first determined in step 5266 whether or not the discharge sensor 2 rise flag is II II II.

If this determination result is "NO", that is, the ejection of the prize ball has not yet been detected by the ejection sensor 2 even though the ejection of the prize ball has been started by the excitation (ON) of the ejection solenoid 2 in the above-mentioned ejection start process. , followed by step 526
Steps 8 through 5274 and step 8264 are skipped, and this routine ends.

On the other hand, if the determination result in step 5266 is 'Yes',
That is, when it is confirmed by the discharge sensor 2 that the prize ball has reached the sensor (the discharge sensor 2 rising flag is it I n ), the value of the discharge register O at this point is crossed and subtracted (step 3268). , the discharge sensor 2 startup flag is reset to P0'' (step 5270), and the process proceeds to step 5272.

In step 5272, it is determined whether the subtracted value is "1" or not, and this result is IIN.

That is, by energizing (ON) the ejection solenoid 2, the prize ball is ejected from the second prize ball ejecting device, and the ejection sensor 2
When it is determined that the number of prize balls detected has not reached the "set number of prize balls - 1", step 5274 and step 5264 are skipped, and this routine is ended.

On the other hand, the determination result of step 5272 is 1lyeS''
That is, when the ejection of prize balls is started by the excitation (ON) of the ejection solenoid 2 in the above-mentioned ejection start process, and the ejection sensor 2 detects "the set number of prize balls - 1" prize balls, the above-mentioned prize Assuming that the ejection of the set number of prize balls has been completed, the ejection solenoid 2 is demagnetized (OFF) L in step 5274, and the ejection end flag is set to 1'' in step 5264. This routine ends.

By the way, as mentioned above, also in the ejection process on the second prize ball ejecting device 740 side, when the ejection sensor 2 detects the number of prize balls equal to "set number of prize balls - 1", the "set number of prize balls" is set. The reason why it is assumed that all the prize balls have been ejected is the same as the reason described in the ejection process on the first prize ball ejecting device 740 side.

FIG. 35 is a flowchart showing a subroutine of the combined discharge process performed in step 5212 of the discharge process (FIG. 32) described above.

As mentioned above, this routine is a process that is performed when the number of prize balls to be ejected (number of prize balls set) is 9 or more (but 15 or less), and the first and second prize balls are processed in one loop of processing. The prize balls are ejected simultaneously by the ejecting devices 740, 740 (if the set number of prize balls is an odd number, the last one
The balls are ejected by one of the devices, for example the first prize ball ejector).

When this routine starts, in step 5302, the discharge 1
It is determined whether the end flag is l'''.This ejection 1 end flag is the number of prize balls to be ejected by the first prize ball ejecting device (hereinafter referred to as "first divided prize ball number"). 1'' in step 5314, which will be described later.
It is set to .

If the determination result in step 5302 is "No," that is, the first prize ball discharging device has not yet completed discharging the first divided prize balls set in the discharging division process (FIG. 31). If not, the following steps 8304 to 5314
processing is performed.

First, in step 5304, the discharge sensor 1 startup flag is set to o.
1 ++ or not is determined, and this result is “No.
That is, after the ejection solenoid 1 is energized (ON) in step 5140 of the above-described ejection start process (FIG. 29), if the ejection of the prize ball has not yet been detected by the ejection sensor l, the subsequent steps 3306 to 3306 are performed. 531
4, further skipping step 5316 described below,
The process proceeds to step 5318 and subsequent steps.

On the other hand, when the determination result is 'Yes', the value of the ejection sensor 1 startup flag indicating that one prize ball has been ejected is reset from '1' to 'O'" (step 5306). , the value of the discharge register 1 is subtracted by 1 (step 5308), and it is further determined whether the subtracted value has reached "l" (step 5310).

The determination result of step 5310 is "No", that is, the number of prize balls ejected by the first prize ball ejecting device and detected by the ejection sensor 1 has reached [first divided number of prize balls - 1]. If not, the following step S3]2
．． Skip steps 5314 and 5316 and proceed directly to steps 3318 and subsequent steps.

On the other hand, the determination result in step 5310 is “Yes”.
That is, when the number of prize balls ejected by the first prize ball ejecting device and detected by the ejection sensor 1 becomes [first divided prize ball number - 1], the number of prize balls equal to the first divided prize ball number is Assuming that all the prize balls have been put out, the discharge ball and Noid 1 are demagnetized (OFF) (step 5312), and the first
In order to memorize that the ejection of the prize balls by the prize ball ejecting device has been completed, the ejection 1 end flag is set to P1''' (step S314), and the process proceeds to step 5316 onward.Therefore, the first divided prize balls are When the determination in step 5302 is made after all the prize balls have been ejected for several minutes, steps 8304 to 5314 are skipped;
The process will directly proceed to step 5316 and subsequent steps.

In step 5316, it is determined whether the discharge 2 end flag is "1". This discharge 2 end flag is the second
When the prize ball ejecting device has completed ejecting the prize balls for the number of prize balls to be ejected (hereinafter referred to as the "second divided number of prize balls"),
This is set to ``1'' in step 5328, which will be described later.

If the determination result in step 5316 is "No," that is, at this point, the second prize ball ejecting device is still distributing the prizes equal to the second divided number of prize balls set in the ejected number division process (FIG. 31). If the ejection of the ball is not completed, step 8
Processes 318 to 5330 are performed 7 First, in step 5318, the discharge sensor 2 startup flag is set to I.
It is determined whether or not I i II, and this result is "'
No, that is, step 5142 of the discharge start process described above.
After the ejection solenoid 2 is energized (ON) L, if the ejection sensor 2 does not detect any ejection of prize balls yet, the following steps 3320 to 5332 are skipped and the present routine is directly ended.

On the other hand, when the determination result in step 3318 is 'Yes', the value of the discharge sensor 2 rising flag (at this time "1") indicating that one prize ball has been discharged is set to °'O''.
(step 5320), and subtracts the value of the discharge register 2 by 1 (step 5322), and further determines whether the subtracted value has reached 1J (step 5324).

The determination result in step 5324 is "N o '", that is, the number of prize balls ejected by the second prize ball ejecting device and detected by the ejection sensor 2 has reached [second divided number of prize balls - IJ]. If not, follow step 5.
326,5328. This routine is ended by skipping S33° and step 5332.

On the other hand, if the determination result in step 5324 is Yes,
That is, when the number of prize balls ejected by the second prize ball ejecting device and detected by the ejection sensor 2 becomes "second divided prize ball number - ■", the prize equal to the second divided prize ball number is given out. Assuming that all the balls have been taken, the ejection solenoid 2 is demagnetized (turned OFF) (step 5326), and the ejection 2 end flag is set to remember that ejection of the prize balls by the second prize ball ejection device has been completed. "lII" (step 5328), and it is determined whether the value of the discharge 1 end flag at this point is "bi" (step S330).
.

When the determination result in step 5330 is I N Or-, the following step 5332 is skipped and this routine ends.

When the determination result in step 5330 is °'Yes'',
If the determination result in step S:316 is “Yes+
Step 5332, which is performed when the value is + (at this time, the ejection l end flag is always II II II to indicate that the ejection of the set number of prize balls has been completed by the combined ejection juice 1 process). Then, set the discharge end flag to 1'', and then end this routine.

As shown above, when the set number of prize balls is set to a large value (9 to 15), the set number is divided and the value is stored in the two ejection registers 1 and 2, and the value is stored in the ejection registers 1 and 2. By independently operating the first and second prize ball discharge devices based on the value of 2, a large number of prize balls can be discharged more quickly.

In addition, even in the combined discharge process for J'''), when the number of prize balls equal to 1 prize ball set number - 1 is detected by the discharge sensor 1.2, the "prize ball set number 1 minute" is detected. The reason why all of the prize balls are considered to have been ejected is the same as the reason stated in the explanation of the alternate ejection process.

Next, we will explain up to this point, and if a power outage occurs during the processing of prize ball ejection control using the created prize ball ejection control device and the power supply from the main power source is stopped, the prize will be performed as a backup process. The power down interrupt process on the ball ejection control device side will be explained with reference to FIG. 36.

This power down interrupt process is performed by the prize ball discharge control device 60.
When the power supply monitoring circuit 680a (see Fig. 13), which constantly monitors the power supply voltage from the main power supply (not shown) supplied to the main power supply 0, outputs a signal indicating a power outage state, the main routine that was being executed up to that point is output. (Figure 14) and interrupt processing (
This process is started in place of Figure 18), and while minimizing the power consumption after a power outage occurs, the determination of game balls that have not yet been determined as safe/out is made as specified after a power outage occurs. A process to be executed over a period of time (the safe detection timer counts C), a process to determine whether or not the output signal of the safe sensor 830a occurring at that time is due to a winning of a safe ball; Furthermore, in the event of a power outage, backup processing is performed to eliminate the existence of safe balls with unpaid prize balls.

First, when the occurrence of a power outage is detected based on a signal from the power supply monitoring circuit 680a and this process is started, various components such as the safe bulb outflow prevention solenoid 851, the firing motor 151, the ejection solenoids 1 and 2, and the shutter solenoid 910 are activated. The power supply to the operating part is stopped (output reset) (
step 530). In particular, by demagnetizing (turning off) the safe ball outflow prevention solenoid 851 when a power outage occurs as described above, the safe ball that won before the power outage and whose winning has not yet been detected by the safe sensor can be removed from the safe ball. It can be kept in the sensor by a ball outflow prevention solenoid 851 (FIG. 8(B)).

Next, in step S31, the safe detection timer is incremented to a predetermined value (for example, 5se+jG).This safe detection timer is activated when the safe bulb actually flows out after the demagnetized safe bulb outflow prevention solenoid 851 is demagnetized. This is to measure the time until the ball is stopped and the time interval from the rise to the fall of the output signal of the safe sensor, and count the time longer than the predetermined time required to complete the safe ball determination process.

After the safe detection timer is set, step S32
By forcibly resetting the processing NO in the event of a power outage, the process NO is reset to (I OI+). By forcibly resetting the process NO during a power outage, the process to start discharging the prize ball or the discharging process (see FIG. 29 or Even if a power outage occurs while Figure 32) is being executed, the ejection of prize balls for the safe ball will be restarted from the beginning, so that the player will not be disadvantaged. Become.

In the next step S33, it is determined whether the safe storage value is rQJ or not, and the determination result is "N".

That is, at this point (when a power outage occurs), if there are still winning balls (hereinafter referred to as "remaining balls") for which the corresponding prize balls have not been completely ejected, a message to that effect is displayed in step S34. Ejected remaining ball indicator lamp 4 of information display device 400
45c is turned on (ON), and then the process proceeds to step S35. On the other hand, if the determination result is "Yes", the process directly proceeds to step S35.

In step S35, it is determined whether or not the safe detection timer set in step S3 has timed up.
If the determination result is "No", that is, the predetermined time (5 seconds) has not yet elapsed after the power outage occurred, and therefore, there is a possibility that the safe sensor will detect game balls whose outflow has not been prevented by the safe ball outflow prevention solenoid. ,
In step S36, the timer is updated, and in step S37, safe sensor input processing (FIG. 21) is performed using the same procedure as that performed in the interrupt processing described above, and further, in step 338, this is also performed as described above. After performing the safe ball determination process (FIG. 28) using the same procedure as that performed in the interrupt process, the determination result in step S35 is 'i y
The process in step S33 is repeated until the process changes to es++.

Therefore, the safe sensor manual process in step S37 and the safe ball determination process in step S38 are repeatedly executed until the L distribution predetermined time elapses from the occurrence of a power outage, and the safe ball outflow prevention solenoid prevents the outflow. It becomes possible to reliably detect the safe ball that has not been blocked by the safe sensor, and further to determine whether or not the sensor output indicating the safe ball is normal.

Step S35 when the predetermined time has elapsed after the power outage occurred.
If the determination result is 'Yes''), end this routine and
The prize ball discharge control device 600 shifts to standby mode.

This standby mode is activated by the power supply voltage supplied from the auxiliary power supply circuit 680b (13th 1) during a power outage.
This is a mode for ensuring the functions (maintenance of stored values, display on the information display device 400, etc.), and the amount of electricity consumed at that time is also suppressed to the necessary minimum.

That is, in the control performed on the prize ball discharge control device 600 side, if a power outage occurs during normal control processing (the main routine in FIG. 14, the interrupt processing in FIG. Since the safe sensor input processing and safe ball judgment processing can continue to be processed for a period of time, and the system then shifts to standby mode, the auxiliary power supply supplied to the prize ball discharge control device 600 after a power outage occurs. By simply ensuring the minimum amount of power from the circuit required for detecting winning balls and determining safe sensor output, winning balls can now be effectively processed immediately after a power outage, which was previously considered invalid due to a power outage. Become.

In addition, after the above-mentioned predetermined time has elapsed, all that is required is at least enough power to memorize and retain the safe memory value, and therefore the backup battery used as an auxiliary power supply is also small enough to be able to cope with long-term power outages. .

As described above, in the prize ball discharge control system of the pachinko gaming machine of this embodiment, the safe sensor 830 is provided with a short detection section (circuit), and the MPU 620 of the prize ball discharge control device 600 is provided with the safe sensor 830. Pulse width detection unit 160 that measures the pulse width of the pulse signal from 830
3 is provided, and a failure state of the safe sensor (short, open, illegal state, etc.) is detected based on a signal from at least one of the short detection section and the pulse width detection section, and at this time, failure processing (notification of failure occurrence) is performed. On the other hand, when no fault condition is detected, the safe ball determination section receives a signal from the pulse width detection section and sends a signal to eject the prize ball. Therefore, the occurrence of a failure can be detected quickly and accurately, and the disadvantage to the player caused by the occurrence of the failure can be appropriately compensated. In particular, in this embodiment, when a failure (error) condition is detected, the safe ball outflow prevention solenoid 851 installed in the winning ball guide channel is demagnetized, and the outflow of the safe balls in the winning ball guide channel is immediately prevented. Therefore, it becomes possible to appropriately compensate for the number of unpaid prize balls corresponding to the number of safe balls that are unpaid due to the occurrence of a malfunction.

The prize ball discharge control device 600 also includes a safe ball determining means for determining whether or not the pulse width of the output signal of the safe sensor 830 detected by the pulse width detection unit 1603 is caused by a winning of a safe ball. 1604 is provided, so only the waveform output signal that may be generated by winning the safe ball is processed as a regular output signal, and the output signal generated due to noise or foreign matter entering the safe sensor is treated as a prize. Balls are excluded from the target of discharge control, thereby increasing the accuracy of prize ball discharge control and making it possible to provide players with a fair pachinko game.

In this embodiment, the pulse width of the sensor is set to the first predetermined value (4
m5ec) and the second predetermined value (50m5ec), it is determined that the safe ball has won, and the third predetermined value (l
Q Qmsec) or more, it is determined that an error (failure or fraud) has occurred, but in the above determination, if the pulse width is equal to or greater than the second predetermined value, it is immediately determined to be an error. It's okay.

In addition, in this embodiment, among the modes of failure (error) of the safe sensor, a short state is detected by a short detection section provided inside the sensor, and an open state is detected by the prize ball discharge control device that receives the output signal of the sensor. MPU620
(Pulse Width Detection Unit 1603), but the present invention is not limited to this, and the MPU 620 may detect both the short state and the open state, or the sensor itself may detect the open state. A circuit for detection may be added. Furthermore, contrary to the embodiment, a circuit for detecting an open state may be configured in the sensor, and the MPU 620 may detect a short state.

In addition, in this embodiment, in order to determine whether or not the output signal of the safe sensor indicates a winning of a safe ball, the sensor 8 measures the fall of the force in real time from ri to fall, and this is determined by a plurality of predetermined values (C). ff, (first to third predetermined values), but contrary to the embodiment, the above FI'!4 value is measured and the output state at this time is similarly monitored. Even if you do this, the same effect can be obtained.

Furthermore, the first to third predetermined values are not limited to the values shown in the examples, but may be determined experimentally depending on the back mechanism panel of the pachinko game machine, or may be values that have been set experimentally. It may be changed periodically in accordance with changes over time in the prize ball discharge control system.

Further, in this embodiment, a pachinko game machine with one type of prize ball setting number, that is, a pachinko game machine with one winning ball processing system, such as a winning ball receiving gutter 810 and a winning ball leading out gutter 820, has been described, but the present invention The control device for the pachinko game machine related to
A pachinko game machine with two types of prize ball settings (in this case, the winning ball receiving gutter, winning ball leading out gutter, etc. are provided in two independent rows, and two safe sensors are installed in each of the winning ball leading out gutter in the above two rows). Of course, it is also applicable to the above-mentioned two safe sensors, and the above-described control may be performed on the outputs of the two safe sensors.

In addition, in this example, there are two drainage channels for discharging prize balls (the first
．． Although an example of a pachinko game machine with a second prize ball derivation gutter has been shown, the present invention is not limited to this, and the present invention can be applied to a pachinko game machine equipped with a single derivation gutter or three or more derivation gutter. is also possible.

[Effects of the Invention] As detailed above, the prize ball discharge control system for a pachinko game machine of the present invention includes a winning ball detector stage that detects winning balls and outputs a pulse signal as a calibration signal, and a winning ball detector stage that detects winning balls and outputs a pulse signal as a calibration signal. A pulse width detection means for measuring the pulse width; and when the pulse width measured by the pulse width detection means is within a predetermined appropriate range, the ball is determined to be a winning ball and a winning signal is output. a winning ball determining means for outputting; and a failure inspection means for outputting a failure signal when it is determined that the pulse width measured by the pulse width detection means is within a predetermined range that should be considered a failure; , comprises a prize ball discharging means for discharging prize balls based on the winning signal from the entered prize ball determining means, and a failure processing means for performing failure processing based on the failure signal from the failure checking means,
The accuracy of winning ball detection has been improved, and the ejection of prize balls is now more accurate than before.
On the other hand, since the structure is such that a failure of the winning ball inspection means itself can be detected based on the signal representing the pulse width from the pulse width detection means, the occurrence of a failure can be detected quickly, and compensation for the disadvantage caused by the occurrence of the failure can be provided. This can be done smoothly and accurately, and troubles between players and game parlors regarding the number of prize balls to be ejected when a malfunction occurs can be prevented.
