Description

TECHNICAL FIELD The present invention relates to a ball game machine represented by a pachinko game machine and the like, and more particularly, to a variable display device capable of variably displaying a plurality of types of identification information. However, the present invention relates to a ball game machine capable of imparting a predetermined game value when the display result when the variable display device is variable stopped is a combination of predetermined specific identification information.

[Prior Art] Among the ball game machines of this type, one generally known from the past has been described in, for example, JP-A-59-55273. In this conventional ball game machine, the variable display device is variably displayed when a predetermined condition such as a driving ball wins a start is satisfied, and then the variable display device is stop-controlled and then stopped. It is configured such that a predetermined game value can be given when the display result of the variable display device becomes predetermined specific identification information.
Then, in the conventional variable display device of this type of ball game machine, for example, a rotating member on the outer periphery of which identification information such as a plurality of types of symbols is drawn, and a drive source for rotationally driving the rotating member. Is provided, and the plurality of types of identification information are variably displayed by rotating the rotating member.

[Problems to be Solved by the Invention] As described above, in this type of ball game machine, it may or may not be possible to add a game value depending on the display result when the variable display device is stopped in a variable manner. The display control of the variable display device is a very important control.

However, in the conventional ball game machine, the rotation of the rotating member is caused by various causes such as dust adhering to the rotating member, the rotation of the rotating member being stopped by an external action, and the rotation resistance increasing. Abnormalities sometimes occurred. That is, there is a case in which a rotation abnormality occurs in which the rotation member is not actually rotating that way even though the rotation member is controlled to rotate by a predetermined rotation angle. In such a case, there arises a disadvantage that the variable display of the variable display device is not normally performed normally, and when the detection of the rotation abnormality of the rotating member is delayed, the rotation abnormality repair work is also performed. If it is left for a long time with a delay or abnormal rotation, there is a drawback.

The present invention has been conceived in view of such business, and an object thereof is to reduce inconvenience caused by abnormal rotation of a rotating member provided in a variable display device as much as possible.

[Means for Solving the Problem] The present invention has a variable display device capable of variably displaying a plurality of types of identification information, and the display result when the variable display device is variably stopped is predetermined identification information. In a ball game machine capable of imparting a predetermined game value in the case of a combination of, the variable display device includes a rotating member having the plurality of types of identification information on its outer periphery, and the rotating member. A drive source for rotationally driving, and a reference position detecting means for detecting that the rotation of the rotating member has reached a predetermined rotation reference position, the ball game machine is configured to rotate the drive source by a predetermined rotation. Rotational drive control means for performing rotational drive control by advancing by angle, and abnormal rotation of the rotating member has occurred based on the detection result of the reference position detection means and the rotational angle step control amount by the rotational drive control means. Time to judge that Characterized in that it comprises an abnormality determination means.

[Operation] According to the present invention, the variable display device has a rotating member having a plurality of types of identification information on its outer periphery, a drive source for rotationally driving the rotating member, and a predetermined rotation of the rotating member. Reference position detecting means for detecting that the rotation source has reached the rotation reference position is provided, and the drive of the drive source is stepped by a predetermined rotation angle by the operation of the rotation drive control means to control the rotation drive. Then, by the operation of the rotation abnormality determination means, it is determined that the rotation abnormality of the rotating member has occurred, based on the detection result of the reference position detection means and the rotation angle step control amount by the rotation drive control means. In other words, when the rotating member is rotating normally, a predetermined correlation between the rotation angle step control amount of the rotation drive control means and the detection signal of the reference position of the rotating member which is rotationally driven by the drive source ( The relationship that the reference position is detected when the rotation angle step control amount reaches a certain predetermined amount) is established, and the detection result of the reference position detection means and the rotation angle step control amount by the rotation drive control means are established. It is possible to determine that the rotation abnormality of the rotating member has occurred by determining whether or not the predetermined correlation is established based on the above.

A predetermined DC current is supplied from the power supply circuit 81 to the various devices and the control circuit.

6A to 6E are flowcharts for explaining the operation of the control circuit shown in FIG. FIG. 6A shows the main routine.
It is executed once every time a reset pulse oscillated every 2 msec is given. The motor control process of step S (hereinafter simply referred to as S) 5 shown in FIG. 6A will be described later.
The switch check processing of S6 shown in FIG. 6B will be described later in 6C.
Shown in Figures through Figure 6E. The details of S3 and S4 are omitted. Next, by S8, the stop symbol determination counter is counted up, but the processing of this S8 is the reset waiting time (the time from the completion of the main processing from S1 to S7 until the reset pulse is input). Repeated during the period. Since the processing time for one main process (S1 to S7) changes depending on the game state, the number of times S8 is processed is not constant. Then, every time the process of S8 is performed, the stop symbol determination counter is incremented by "+1". This stop symbol determination counter consists of a hexadecimal counter, 00
There are 4096 possible values from 0 to FFF, which correspond to each drum in order from the upper right drum, middle drum, left drum.

FIG. 6B is a flowchart showing the subroutine program defined by S5. By S9 to S11, it is judged whether or not each of the motor deceleration flag, the motor constant speed flag and the motor acceleration flag is set, and when all of these flags are not set, the process proceeds to S12. Here, the motor deceleration flag is for smoothly decelerating the stepping motors 53a to 53c (see FIG. 4) for rotationally driving the rotary drum, and is set by S24 described later and cleared by S49. It is a thing. The motor constant speed flag is for rotating the stepping motor at a constant speed, and is set by S20 described later and cleared by S24. The motor acceleration flag is for smoothly accelerating the stepping motor, and is set by S18 described later and cleared by S20.

In S12, it is determined whether or not the jackpot flag is set. This big hit flag is set in S47 described later. If the jackpot flag has already been set, the subroutine program ends, but if it has not been set, S1
Then, it is judged whether or not the starting memory counter is "0", and if it is "0", the subroutine program is terminated as it is, but if it is not "0", the program proceeds to S14.
A determination is made as to whether the out-of-range interval timer has expired. This out-of-range interval timer is for measuring the time of about 1 second necessary for the player to recognize the identification information when the variable display device is out of order. It is set. If the out-of-range interval timer has not yet expired, the subroutine program ends as it is. While this deviation interval timer has not expired, a determination of NO is made by S14 each time this subroutine program is executed, but when the deviation interval timer has expired, a determination of YES is made by S14 and the process proceeds to S15 and the stop symbol A process of calling the stop symbol data in the area 1 of the data storage area and storing it in another area is performed. The stop symbol data storage area is an area for storing the current count value of the stop symbol determination counter according to the process of S57 described later, and has a storage area corresponding to the value (1 to 4) of the start storage counter. Then, as will be described later, the value of the stop symbol determination counter at the time of starting winning (see S8) is stored in the storage area corresponding to the value of the starting memory counter, and, for example, the value of the starting memory counter at the time of starting winning is " If it is "3", it is stored in the third area. Then, by S15, the stop symbol data in the stop symbol data storage area 1, that is, the oldest start winning stop symbol data among the stored starting prizes is called and stored in another area. What is stored in this separate area is the data of the planned stop design in this variable display. Next, the process proceeds to S16, the start memory counter is decremented by 1, and the stored contents of the stop symbol data memory area are completely shifted one by one from 4 to 1 in S17. For example, the stop symbol data stored in the stop symbol data storage area 2 until now is stored in the stop symbol data storage area 1 when the process of S17 is performed. Then S18
Then, the basic timer is set, the motor acceleration flag is set, and the motor acceleration pattern data is set. This basic timer measures the basic time when the variable display device is automatically stopped, and measures, for example, about 4.9 seconds. The motor acceleration pattern data is data for smoothly accelerating the motor over a predetermined time. Next, proceeding to S43, processing for counting the number of steps of the stepping motor is performed, and the subroutine program ends. The S43 constitutes output number counting means for counting the output number of the rotation angle stepping signal.

This motor control subroutine program is executed, for example, once every 2 msec. Since the motor acceleration flag has already been set in S18 in the previous execution, a YES determination is made in S11 in this execution. Proceed to S19. In S19, it is determined whether or not the motor acceleration pattern data has ended. Until the motor acceleration pattern data ends, NO is determined in S19, the number of steps is counted in S43, and the subroutine program ends. When it is determined that the stepping motor is sufficiently accelerated and the motor acceleration pattern data is completed, the process proceeds to S20, the motor acceleration flag is cleared, the motor constant speed flag is set, and the process proceeds to S43.

Then, when the subsequent motor control subroutine program is executed, since the motor constant speed flag has already been set in S20, a YES determination is made in S10 and the process proceeds to S21 to determine whether the basic timer has ended. Is judged. This basic timer is the one set by S18, and when it is not finished,
In S22, it is determined whether or not the stop flag is set. If the stop flag is not set, the process proceeds to S43. This stop flag is set by S64, which will be described later, based on the pressing operation of the stop operation button 8 (see FIG. 1) by the player. Then, if the player presses the stop operation button 8 (see FIG. 1) before the basic timer expires or before it expires, the process proceeds to S23, and the subsequent stop control of the variable display device is performed. First, in S23, it is determined whether or not the symbol is in the middle. The determination in S23 is to wait until the symbol comes to the center position when the symbol is not at the center position when the stop condition is satisfied, and NO when the symbol comes to the center position.
Is made and the process proceeds to S24. In S24, processing for clearing the stop flag, clearing the motor constant speed flag, and setting the motor deceleration flag is performed. Then, the process proceeds to S25, and it is determined whether or not the value for the left symbol in another area (see S15) satisfies the big hit condition. If the value for the left pattern in the other area corresponds to one of the big hit displays of "7", "FEVER", "BAR", and "SANKYO", YES is determined in S25 and the process proceeds to S27. In S27, it is determined whether or not the values for the left and right symbols in different areas satisfy the big hit condition, and if they are satisfied, the process proceeds to S29, in which the deceleration pattern data for each motor is based on the current symbol and the planned stop symbol. Is selected and set, and the process proceeds to S43. The current symbol is the data of the symbol positioned on the central display line of the variable display device when the process of S29 is performed, and the planned stop symbol is the stop symbol data stored in another area by S15. . When the deceleration pattern data of each stepping motor is selected and set, each stepping motor simultaneously enters the deceleration pattern. In addition, 16 types of this deceleration pattern data are prepared in advance for each motor. In addition, no matter what combination is used, the stepping motor 53a for the left drum, the stepping motor 53c for the right drum, and the stepping motor 53b for the central drum are set to stop in this order. . According to the deceleration pattern data of each motor set in S29, each motor is sequentially stopped and controlled with a predetermined time difference.

On the other hand, if the value for the left symbol in another area does not satisfy the big hit condition in S25, the process proceeds to S26, where the stepping motor A for the left drum is decelerated based on the current symbol and the value for the left symbol in the other area. The pattern data is selected and set, and the deceleration pattern data that can stop the stepping motor C for the right drum and the stepping motor B for the central drum in the shortest time is selected and set, and the process proceeds to S43.
In other words, when the identification information displayed on the left variable display portion which is first stop-controlled does not satisfy the big hit condition, the left drum is normally stop-controlled. The right drum and the center drum are stopped and controlled in the shortest time. Next, by S27, if the value for the left and right symbols in the different area does not satisfy the big hit condition, the process proceeds to S28, where the stepping motor A for the left drum is based on the current symbol and the value for the left and right symbols in the different area. Then, the deceleration pattern data of the stepping motor C for the right drum is selected and set, the deceleration pattern data that can stop the stepping motor B for the central drum in the shortest time is selected and set, and the process proceeds to S43. In other words, when the stop design of the variable display on the left satisfies the big hit condition, but the stop design of the variable display on the right does not satisfy the big hit condition in combination with the left, S2
When NO is determined by 7, the left and right drums are sequentially stopped and controlled as usual, while the central drum is stopped and controlled in the shortest time. Thus, in the case of S26, the left pattern S28
In the case of, the left and right symbols are stopped and controlled based on the data selected at the time of starting winning, but for the rest, regardless of the data selected at the time of starting winning, the deceleration pattern prepared (16 types in this embodiment) ), Select the deceleration pattern data that can be stopped in the shortest time. in this way,
In the first embodiment, the display content displayed on the identification information display unit that stops first is set to the display content that was determined at the time of winning the start prize, but the display content that is determined first also for the one that stops first. If is out of range, the display content may be changed so that the display can be stopped in the shortest time within the range of out of range. Further, when there are a plurality of identification information display sections that are being variably displayed when the deviation is confirmed, the remaining variable display sections may be stopped at the same time or almost the same time.

Since the motor deceleration flag is set by S24,
At the next execution of the motor control subroutine program, YES is determined in S9 and the process proceeds to S30.
In S30, it is judged whether or not the stepping motor A deceleration pattern data is completed, and if it is not completed,
The process proceeds to S31, it is determined whether or not this time is ended, and if not this time, the process proceeds to S43. When ending this time, the process proceeds to S32, and after the stepping motor A is stopped and controlled, the process proceeds to S43. At the next execution of the motor control subroutine program, since the deceleration pattern data of the stepping motor A is completed, S3
When YES is determined by 0, the process proceeds to S33, and it is determined whether or not the deceleration pattern data of the stepping motor C is finished. If it is not finished yet, the process proceeds to S34, and it is determined whether or not this time is finished. If you want to end this time
Proceed to S35. In S35, the stepping motor C is stopped and controlled, and the process proceeds to S36, in which it is determined whether the left and right stop symbols satisfy the big hit condition. If not satisfied, the process proceeds directly to S43, but is satisfied. In this case, the process proceeds to S37, sets the reach flag, and then proceeds to S43. By this S36
As a specific example of the case where the determination of YES is made, for example, when the combination of the big hit symbols is "777", the symbols when the left drum and the right drum are both stopped are "7". .

At the next execution of the motor control subroutine program, YES is determined in S33 and the process proceeds to S38, it is determined whether or not the stepping motor B deceleration pattern data is finished, and if it is not finished yet, S39 is performed. Then, it is determined whether or not to end this time. If it is to end this time, the process proceeds to S40 to determine whether or not the reach flag is set. When the reach flag is not set, the process proceeds to S45, and the stopping control of the stepping motor B is performed as it is, but when the reach flag is set according to S37, the process proceeds to S41, and the data for increasing three revolutions is set. Proceed to S43. By setting the 3-rotation increase data, the central rotating drum slowly rotates for a longer time than usual, and the effect of further encouraging the player's expectation can be expected.

At the next execution of the motor control subroutine program, YES is determined in S39, the process proceeds to S42, and it is determined whether or not the data for increasing three revolutions is completed. And if not finished yet, the result of S42 is NO.
Therefore, every time the motor control subroutine program is executed until NO at step S42, the determination of NO is continued. When the data for increasing three revolutions is completed, YES is determined in S42, the process proceeds to S44, the reach flag is cleared, the process proceeds to S45, and the stop control of the stepping motor B is performed. Then, the process proceeds to S46, where it is determined whether or not the left, middle, and right stop symbols satisfy the jackpot condition. If the jackpot condition is satisfied, the process proceeds to S47, the jackpot flag is set, and the jackpot interval timer is set. To do. This big hit interval timer is a waiting time until the opening / closing plate 22 of the variable winning ball device 20 (see FIG. 1) is opened. next
Progressing to S49, the motor deceleration flag is cleared and the subroutine program ends. On the other hand, if the left, middle, and right stop symbols do not satisfy the jackpot condition, proceed to S48,
The falling interval timer is set and the process proceeds to S49.
On the other hand, when the big hit flag is set, the solenoid 40 is controlled to open / close the opening / closing plate 22 (see FIG. 1) of the variable winning ball device based on the flag. Omit the program. In this solenoid control processing program, when the big hit control is completed, the big hit flag set in S47 is cleared.

FIG. 6C is a flow chart showing a start switch check subroutine program in the switch check processing defined in S6. By S50, it is determined whether or not the start switch (starting winning ball detectors 43a to 43c) is ON. When the pachinko ball wins any of the starting winning openings 27a to 27c, YES is determined in S50 and the process proceeds to S52, in which it is determined whether the start switch check counter is maximum. The start switch check counter is incremented by "1" by S53 each time the start switch check subroutine program is executed, and its maximum value is "255", for example. If the maximum value has not been reached yet, the process proceeds to S53, the check counter is incremented by 1, and the process proceeds to S54, in which it is determined whether or not the start switch check counter = “3”. If "3" has not been reached yet, the subroutine program ends, but if "3" is reached, S5 is executed.
Proceeding to 5, it is judged whether or not the start memory counter = “4”. Since the upper limit value of the starting memory counter is "4", if the upper limit value "4" has already been reached, the subroutine program ends as it is, but if it has not reached "4" yet. Advances to S56, and the addition processing of "1" of the start memory counter is performed in accordance with the occurrence of the start winning. Next, in S57, a process of storing the current count value of the stop symbol determination counter as stop symbol data in the stop symbol data storage area corresponding to the value of the start storage counter is performed. For example, when the starting memory counter is "1", the stop symbol data corresponding to the current count value is stored in the area 1 of the stop symbol data storage area. The stop symbol data storage area corresponding to the value of the starting memory counter is area 1 when the value of the starting memory counter is "1", and area 2 when the value of the starting memory counter is "2". If the starting memory counter is "3", it is area 3, and if the starting memory counter is "4", it is area 4.
Next, when it is determined in S50 that the start switch is not turned on, the process proceeds to S51, the start switch check counter is cleared, and the subroutine program ends. After all, this start switch check subroutine program is executed three times, and only when the start switch is ON all three times, the determination of YES is made by S54, and the processing after S55 is performed, so that the game hall is operated. Even if the start switch is momentarily turned on due to generated noise or the like, the processing after S55 is not performed immediately so that malfunction due to noise can be prevented as much as possible. By the start storage counter described in S56, the start command signal is generated from the time when the start command signal of the start command signal generating means is derived until the end of the variable display control of the variable display unit based on the start command signal. Storage means is configured to store that the start command signal is derived again from the means.

FIG. 6D is a flowchart showing a subroutine program of a stop switch check process in the switch check process shown in S6. When the player presses the stop operation button 8 (see FIG. 1), the stop switch is turned on, the determination of YES is made in S58, the process proceeds to S60, and whether the stop switch check counter is maximum or not is determined. Judgment is made. This stop switch check counter is set to "1" by S61 every time this stop switch check subroutine program is executed.
The maximum value is, for example, "25.
5 ”. If the stop switch check counter has not reached the maximum value yet, the process proceeds to S61, the stop switch check counter is incremented by "1", and the process proceeds to S62. In S62, it is determined whether or not the stop switch check counter is "3", and if it is not "3" yet, the subroutine program ends as it is, but if it is "3", S6
Proceeding to 3, it is judged whether or not the motor constant speed flag is set. This motor constant speed flag is
Set by and cleared by S24.
If the motor constant speed flag is not set, the subroutine program ends as it is, but if the motor constant speed flag is set, the process proceeds to S64, the stop flag is set, and the subroutine program ends. The reason why the stop flag is not set when the motor constant speed flag is not set, that is, when the motor is already in the deceleration stage is that the player presses the stop operation button 8 because the stepping motor has already entered the deceleration stage. This is because the pressing operation is too slow. this
Based on the stop flag set by S64, the S
When YES is determined by 20, the process proceeds to the stop control of the variable display device thereafter. On the other hand, when the stop switch is not ON, the process proceeds to S59, the stop switch check counter is cleared, and the subroutine program ends. The reason why the stop flag is controlled so that the stop flag is set only after the stop switch check counter reaches "3" is to prevent a malfunction due to noise or the like as described in S51 and S54. The S58
Through S64 and S21 and S22, a stop command signal generating means for generating a stop command signal based on the satisfaction of a predetermined stop condition for controlling the variable display of the variable display section is configured. There is.

FIG. 6E is a flowchart showing a subroutine program of the drum position switch check in the switch check processing stopped in S6. First, in S65, it is determined whether or not the step counter A = “96”. This "96" is the maximum value of the step counter. Further, it is determined in S68 and S71 whether the step counter B and the step counter C are "96", respectively. When all the step counters A, B and C are not "96", the subroutine program is finished as it is. On the other hand, when the step counter A of the stepping motor for the left drum has the maximum value "96", the drum position switch A for the left drum (the drum position detector 57
If a) should be turned on, and if it is not turned on, it is possible that the stepping motor has failed or the rotating drum has been forcibly stopped improperly. The advance alarm flag is set and the subroutine program ends. According to the setting of this alarm flag, an alarm sound is generated from the speaker 7 (see FIG. 1) or the like. It should be noted that the drum position switch B for the middle drum and the drum position switch C for the right drum are similarly determined in S69 and S72 to determine whether they are ON, and if they are not ON, S74. Then, the alarm flag is set. When YES is determined in S66, the process proceeds to S67 and the step counter A is cleared. Similarly, the step counter B and the step counter C are also cleared by S70 and S73, respectively. In other words, if the step counter reaches the maximum value of "96", the rotary drum has made one revolution, so the step counter is cleared at that point, and the step counter starts counting up from 0 again. By S65 to S73, based on the detection result of the reference position detection means and the rotation angle step control amount by the rotation drive control means, the rotation abnormality determination means for determining that the rotation abnormality of the rotating member has occurred. It is configured.

FIG. 6F is a flow chart showing a changed part of the program when the stop operation button is not provided in the first embodiment. If YES is determined in S10 shown in Fig. 6B, the process proceeds to S21 ', and it is determined whether or not the basic timer has expired. If not, the process proceeds to S43 in Fig. 6B. If it is judged that it is finished, proceed to S23 ′,
It is judged whether or not it is in the middle of the symbol, and if it is judged that it is in the middle of the symbol, the process proceeds to S43, but if it is determined that it is not in the middle of the symbol, the process proceeds to S24 'to clear the motor constant speed flag. The process of setting the motor deceleration flag is done
Proceed to S25. That is, the stop flag is not set because there is no stop operation button, and as a result, it is not necessary to determine whether or not the stop flag in S22 shown in FIG. 6B is set.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to the drawings.

FIG. 7 is a front view showing a variable display device 90 used in the second embodiment. The variable display device 90 is provided with identification information display sections (7-segment LEDs) 91a, 91b, 91c, which are digital displays. The identification information display sections 91a to 91c constitute a variable display section. Further, in the figure, 92a to 92d are start winning prize memory indicators, 93 is a number of times of opening display, and 94 is a normal winning hole. In the variable display device 90 of the second embodiment, the combination of the identification information of the big hits is "111""333".
It is defined in five ways: "555", "777", and "999". And the identification information displayed by one identification information display part is 10 kinds of 0-9. As a result, the probability of a big hit is 5/10 ³ = 1/200. The upper limit values for the big hit control and the start winning memory are the same as those in the first embodiment.
The stop order of the plurality of identification information display sections 91a to 91c is left,
The order is middle and right.

8A to 8D are flowcharts showing the program of the second embodiment. The flow chart of the second embodiment is almost the same as the flow chart of the first embodiment, and therefore, the explanation of the common portions will be omitted and the different points will mainly be explained.

The main routine program shown in FIG. 8A is different from that of the first embodiment in that the 7-segment LED control process is performed by S5. In the first embodiment, each variable display portion is composed of a drum whose rotation is stopped and controlled by a stepping motor, but in the second embodiment, it is composed of a 7-segment LED as shown in FIG. Therefore, in S5, 7-segment LED control processing is performed. Further, in S8, a process of counting up the rotation time determination counter is performed. This rotation time determination counter is composed of a decimal counter and can take 1000 different values from 000 to 999. The 100's place is the right 7 seg, the 10's place is the middle 7 seg, 1
The position of corresponds to the left 7 segment. Then, for example, each time the main routine is executed, the rotation time determination counter is incremented by "+1".

FIG. 8B shows a subroutine program for the 7-segment LED control process defined in S5. This 7-segment LED control processing is similar to the motor control processing shown in FIG. 6B, and the differences will be mainly described. In the second embodiment, the "motor deceleration flag" in the first embodiment becomes the "7 segment stop flag", and the "motor low speed flag" in the first embodiment becomes the "7 segment rotation flag". The "stop symbol data storage area" in the example becomes the "rotation time data storage area". In the first embodiment, it is judged in S11 of FIG. 6B whether or not the motor acceleration flag is set, but in the second embodiment, the control and judgment corresponding thereto are not performed. This is because the motor acceleration flag is set in order to accelerate the stepping motor smoothly over a predetermined period of time, and in the second embodiment, the variable display device is not a rotary drum system using the stepping motor but a 7-segment segment. This is because there is no need to accelerate over a predetermined period of time because the digital variable display method using LEDs is adopted. Further, in the first embodiment, since the symbols are variably displayed by the rotation of the drum, there is a portion for judging whether or not the symbols are in the middle in S23 of FIG. 6B.
In the second embodiment, it is not necessary to judge whether the symbol is in the middle. If the basic timer has expired or if the stop flag is set, the 7-segment rotation flag is cleared and the 7-segment stop flag is set in S21. Next, in S22, a timer for stopping each 7-segment is set based on the rotation time data stored in another area in S14. In the process of S22, 10 types of timers are prepared for each 7-segment depending on the value of the counter for determining the rotation time, and the time depends on the timing when the stop condition is satisfied. Even 7-segment each so that you can stop at all numbers
The time is set according to the rotation speed of the LED.
It is always set to stop in the order of left, middle, and right.
In other words, if it takes 0.2 seconds for the 7-segment LED to change from one number to the next, the stop timer for the left 7-segment LED will be 0, 0.2, 0.4, 0.6 ... 1.6, 1.8. It is prepared. Also, the stop time for medium 7-segment LED is 2.0, 2.2 ... 3.6,
There are 10 types of 3.8. Furthermore, the stop time for the right 7-segment LED is 10 types, 4.0, 4.2 ... 5.6, 5.8.

Next, in S23, it is determined whether or not the left 7-segment stop timer has expired. If not, the process proceeds to S24, and it is determined whether or not to end by subtracting "1".
If it is not ended, the subroutine program is ended as it is, but if it is judged that it is ended, the process proceeds to S25, and the left 7-segment is stop-controlled. Then proceed to S26, left 7
It is judged whether or not the Seg satisfies the big hit condition. If the big hit condition is satisfied, the subroutine program ends, but if the display result does not satisfy the big hit condition, If the start memory counter is "0" and it is determined that the start memory counter is "0", the subroutine program ends as it is, but some start memory is stored in the start memory counter. If it exists, the process proceeds to S28, the 7-segment stop flag is cleared, the deviation interval timer is set, and the subroutine program ends. In other words, if the display result when the left 7-segment LED is stopped is identification information that is unlikely to be a big hit and there is some memory of the start winning, the 7-segment stop flag set by S21 is cleared. However, instead, the deviation interval timer is set. This out-of-range interval timer is for displaying the display result of the out-of-range time of about 0.5 to 1.0 seconds so that the player can recognize the out-of-range. As a result of the processing in S28, when the next subroutine program of the 7-segment LED control processing is executed, NO is determined in S9,
NO is determined by S10 (see S21) and NO by S11.
Is made, and NO is made in S12, and the process proceeds to S13. Then, in S13, it is judged whether or not the out-of-range interval timer has ended, and if it has not ended yet, the subroutine program ends as it is,
When it is determined that the out-of-range interval timer has expired, the processing from S14 onward is executed, and the next variable display control of the variable display device based on the start memory is executed. In other words, if the 7-segment LED on the left does not satisfy the jackpot condition, that is, if the display result is other than 1,3,5,7,9 and there is a memory of the start winning, the middle, right The 7-segment LED is not controlled to stop, and the variable interval control is passed to the next variable display control. Similarly, S32 ~ S
Also in 34, when the display results of the left and middle 7-segment LEDs do not satisfy the big hit condition and there is a memory of the start winning, the right interval is passed without stopping the right 7-segment LED. After that, the process moves to the next variable display control. By S13-S17, S26-S28 and S32-S34, in the process of sequentially stopping the variable display of the plurality of variable display units, the display result of the stopped variable display unit is already a combination of the specific identification information. Without performing the sequential stop control for the variable display section during the variable display thereafter, based on the satisfaction of the predetermined condition including that there is no possibility of being satisfied and that the storage means stores Next-time variable display transition means is configured to start the next variable display of the variable display section based on the storage of the storage means.
Next, FIG. 8C shows a subroutine program of the start switch check processing in the switch check processing defined by the above S6, and FIG. 8D shows a subroutine program of the stop switch check processing. The start switch check processing and stop switch check processing subroutine programs are the same as those in the first embodiment.
It corresponds to the subroutine program of the start switch check process of FIG. 6C and the subroutine program of the stop switch check process of FIG. 6D, respectively, and the control contents are almost the same, so the description thereof is omitted here. In addition, in the pachinko gaming machine without the stop operation button 8 (see FIG. 1), this FIG.
It suffices to delete S19 and S20 in Figure 8B. Next, the drum position switch check process shown in FIG. 6E of the first embodiment is not necessary in the second embodiment.

The present invention is not limited to the first and second embodiments, and is configured to determine each time each of the identification information display units is stopped one by one, whether or not there is a possibility of a specific combination. However, when there is no possibility of a specific combination, the variable display of the remaining identification information display section may be immediately stopped. Further, the variable display device is not limited to the above-mentioned embodiment, and may be a liquid crystal display, a leaf type display or an electroluminescence display. Further, it may be a so-called roulette type in which a plurality of lamps and LEDs are provided and the lamps and LEDs are circulated to variably display while traveling and lighting. Alternatively, a disc type disc may be used in which a plurality of types of identification information are respectively written in a plurality of disc-shaped discs and the identification information at one location of each disc is displayed. Further, a belt type or a dot matrix type may be used. Further, it may be a combination of two or more of the various systems described above.

Further, in the present invention, when the display content determined at the time of the start winning to be displayed on the identification information display section that stops first or second is out of order, the basic timer sets a short time (for example, set to 5 seconds). However, the remaining identification information display unit may be stopped earlier than the normal sequential stop control. Further, as an early stop condition by the early stop control means of the present invention or a transition condition to the next variable display by the next variable display transition means, an operation for the player's early stop or an operation for the next variable display transition is performed. In the first embodiment, the variable display may be stopped early on the condition that the start winning is stored, as in the second embodiment.

[Effects of the Invention] According to the present invention, the rotation abnormality determination means serves to rotate the rotation angle step control amount by the rotation drive control means and the detection result of the reference position detection means. In other words, the rotation of the rotation member is controlled to rotate. Since it is determined that the rotation abnormality of the rotation member has occurred based on the control amount and the rotation amount of the rotation member actually rotated, it is possible to promptly detect that the rotation abnormality of the rotation member in the variable display device has occurred. It is possible to easily discover.
