Variable display deviceAlignment of symbols inIt is about the method.
[0002]
[Prior art]
In pachinko machines and slot machines that have traditionally been used as symbol combination gaming machines, symbol combination combinations can be developed and symbol combinations related to special gaming status and winning status can be established and displayed. It is equipped with a variable symbol display device. In this symbol variable display device, a “drum-type symbol variable display device” having a symbol drum, a “belt-type symbol variable display device” having a symbol belt, a “liquid crystal symbol variable display device” having a liquid crystal panel, etc. Broadly divided. Among these, in the drum-type symbol variable display device and the belt-type symbol variable display device, as its basic form (form), rotational drive control means including a motor (stepping motor or pulse motor), a drive control circuit, and the like, A drum-shaped or belt-shaped symbol display body which forms and arranges a plurality of symbols consisting of numbers, character designs, etc., and a positioning reference for stopping and displaying each symbol on an effective line are detected. For example, a plurality of symbol display units configured to include a detection unit and an illumination unit including a lamp that illuminates the symbol from the inside, for example, in one box frame (usually the left column, the middle column, the right column) 3 units) are set in parallel as a group unit.
[0003]
In the symbol variable display device, as a basic symbol variation control mode related to each symbol combination game, a start condition based on a winning operation of a game ball hit in the game area or a start operation after inserting a coin, Assuming the stop condition based on the stop operation or when the set time elapses, the symbol display unit for each column starts and fluctuates sequentially based on the set condition, and the timely variable stop is set by the motor in the symbol display unit. The final stop symbol is stopped and displayed on the active line side by side.
[0004]
[Problems to be solved by the invention]
By the way, in the case of a display device having a symbol display body in which symbols formed by printing, transfer, etc. are fixedly arranged, such as the drum symbol variable display device and the belt symbol variable display device, from the start of variation. Even if the symbol variation pattern until the variation stop is the same, the symbol displayed before the symbol alignment process and the symbol displayed at the time of variation stop are different each time. There is a difference in the amount of deviation from the displayed symbol, and accordingly, the amount of movement (the amount of rotational movement of the symbol drum or symbol belt) for correcting the amount of deviation is inevitably different. In addition, in the conventional symbol positioning method in the variable symbol display device, the symbol position correction for correcting the deviation amount during the high speed symbol variation is performed in parallel while the rotational speed at the time of the high speed symbol variation is controlled to be constant. Therefore, the symbol variation time varies depending on the amount of deviation. For example, when the movement amount is large, the symbol variation time becomes long. Accordingly, since even the same symbol variation pattern has a plurality of variation time patterns, variation control data covering all variation time patterns that can be generated in each symbol variation pattern is input and set in advance. There is a problem that the necessity of the memory capacity increases and the occupation ratio of the memory capacity increases. Also, when performing the operation inspection, it is troublesome because all the variation time patterns must be inspected.
[0005]
Also, in the above-mentioned stepping motor etc., there is a possibility of slipping during driving due to its drive control system. If slipping occurs, the step unit will shift and the final stop displayed on the effective line will be stopped. The design is shifted from the line and stops. For this reason, in the symbol variable display device, it is necessary to correct the shift amount in units of steps while correcting the shift amount in units of symbols described above. However, in the conventional symbol variable display device, even when the deviation amount in steps is corrected, it is performed with the rotation speed being constant in the same manner as the correction of the deviation amount in symbol units. The symbol variation time changes depending on the size, and the same problem as described above is inherent. In addition, when there are multiple rows of symbol display units, the variation time pattern is different for each symbol display unit, so the stop timing is also different each time, and unnaturalness is exposed to the symbol variation operation, and symbol alignment is performed. It is also pointed out that the player can easily perceive that it is inside.
[0006]
Furthermore, in the conventional variable symbol display device, motor drive control, detection means detection control, illumination means illumination control, and the like are performed on a main board (main control board) that comprehensively controls the pachinko machine. It was. For this reason, when a high-grade symbol variation display is performed, the load on the main board is increased and the operation of the entire pachinko machine is hindered, so that the main board is not overloaded. Only the symbol display function can be provided, and it has been difficult to set game display contents that are varied and varied.
[0007]
OBJECT OF THE INVENTION
  The present invention has been proposed in view of the above-mentioned problems inherent in the prior art described above, and has been proposed to suitably solve this problem. The symbol fluctuation speed at the time of step position correction related to symbol alignment is variable. By controlling to always perform step position correction in the symbol variation pattern in a fixed time, it is possible to reduce the time required for symbol alignment and natural symbol alignment operation, and separately from the main control board The variable symbol display device that can also reduce the load on the main control board by controlling the variable symbol display device with the provided special symbol control boardAlignment of symbols inIt aims to provide a method.
[0008]
[Means for Solving the Problems]
  In order to overcome the above-described problems and to achieve the desired purpose suitably, the present invention provides a control board.(34)Driven based on the fluctuation pattern selected and set insteppingmotor(41)Multiple designsTo rotation direction etc.whileEvery otherArray formationA drum or belt type that is rotated by one pattern by driving the stepping motor (41) at every predetermined step.Symbol display(42), the stepping motor (41) with the symbol display (42)Rotate theThe symbol is changed on the effective line (L), and the symbol display (42) rotates.When stopped, Determined by the control board (34) for each design variationLast stop symbol is valid line(L)Stop displayConfigured asDesign variable display deviceThe method of aligning the symbols,
As the stepping motor (41) is driven in one step, data indicating the current position in steps of one symbol is updated and recorded, and the symbol display (42) is rotated by one symbol. Each time the stepping motor (41) is driven by the step, the data indicating the current position in steps is set to be updated to the reference value,
Corresponding to the deviation amount of the step unit which is the difference between the reference value and the data indicating the current position in the step unit during the alignment process set in the middle of the variation pattern, the symbol display body ( 42) Set the position correction pattern (R) to rotate and move at the required alignment speed (S).
A total value of the shift amount in steps at the time of the alignment process and the movement amount of the symbol display body rotated and moved by the position correction pattern corresponding to the shift amount is constant and rotated by each position correction pattern. Set the rotation time of the symbol display body (42) to be a certain time,
In the alignment process, a position correction pattern (R) corresponding to the shift amount in steps is selected and set.Selected position correction pattern(R)According to the above-mentioned symbol display body(42)By rotating theCorrection for the amount of deviation in stepsAlways a certain timeCompleteIt is characterized by having finished.
[0009]
[Action]
  When aligning symbols, perform “step position correction” processing for a fixed time.In one patternSince the shift in step units can be corrected, if only a small number of position correction patterns are set, all the step position correction processes are suitably performed. In the position correction pattern, the symbol display can always be aligned in a fixed time by rotating the symbol display body at a plurality of alignment speeds for a predetermined time.
  Moreover, it is the same as the speed of change at high speed.First alignment speed and second alignment speed lower than the first alignment speedSince the step position correction is executed at a speed, the processing time required for the symbol alignment is shortened. On the other hand, since the unnatural symbol fluctuation during the step position correction processing does not occur, the player can It is difficult to realize that it is movement.
  Furthermore, since the step position correction process is executed by a special symbol control board independent of the control board that comprehensively controls the pachinko machine, the control board can reduce the load related to the symbol display control.

[0018]
  Next, the symbol variable display device according to the present embodiment configured as described above.Alignment of symbols inA method will be described in which overall control of the symbol variable display device 35 is comprehensively described. The pachinko machine P according to the present embodiment includes the main board 34 that comprehensively controls the pachinko machine P and the special symbol control board that exclusively controls the symbol variable display device 35, as described above and shown in FIG. 50, each command signal and INT signal are transmitted from the main board 34 to the special symbol control board 50, and the special control board 50 transmits the command. The symbol variable display device 35 is controlled based on the signal.
[0019]
(Main board)
In the main board 34, a series of processing programs as shown in FIG. 2 are executed every 2 ms by timer interrupt processing executed every 2 ms. Briefly describing this processing program, when the program is started, the CPU and the like are initially set at step MS1, then the stack pointer is set at step MS2, and the presence of an initial check abnormal value is checked at MS3. If an abnormal initial check value is confirmed in step MS3, the process proceeds to step MS4 to perform initialization processing and wait for a timer interrupt.
[0020]
On the other hand, if the initial check abnormal value is not confirmed in step MS3, the process proceeds to step MS5 to perform output processing. In this output process, the output data for various solenoids 60 that are the operation source of the winning device 26 and the like are created and output, the award ball data, various lamps such as the lighting device 27, LED output data, and various information signals. Are output, various display commands (described later) and an INT signal are transmitted to the special symbol control board 50, and a strobe signal is turned on and off (FIG. 1). In the output process of step MS5 in the processing program, a display command, an INT signal, and the like set based on the processing result in the special symbol process (described later) of step MS13 in the processing program executed before this are transmitted. Is.
[0021]
When the output process is completed in step MS5, the process proceeds to step MS6 and the input process is performed. In this input process, the big hit determination random number and the big hit symbol random number are extracted based on the input of the ball detection signal from each winning switch 49 provided in the start winning tool 21, the normal winning opening 32 and the winning device 26. On the other hand, a random number for hit determination is extracted and stored in the RAM by inputting a detection signal from a detection switch provided at a passage gate or the like. Next, when the input process is completed in step MS6, the process proceeds to step MS7 to perform random number processing. In this random number processing, the big hit determination random number, the big hit symbol random number, the miss symbol random number, the reach determination random number, the fluctuation pattern distribution random number, the hit determination random number, the big hit determination initial value random number, and the like are updated. Further, the process proceeds to step MS8 to perform error processing for determining various errors, and then proceeds to step MS9 to execute a prize ball payout process for creating prize ball data.
[0022]
Then, the process proceeds to step MS10, and if an error is confirmed in the error process in step MS8, the process proceeds to step MS18 without executing the subsequent processes. If no error has been confirmed, the process proceeds to step MS11, where it is determined whether or not this time is an error recovery time. If the error is recovered, the process proceeds to step MS18. If not, the process proceeds to step MS12. The first type special electric accessory processing is executed. In the first type special electric equipment processing, the opening / closing operation control of the opening / closing plate 31 of the special winning opening 30 of the winning device 26 at the time of big hit is performed.
[0023]
Next, in step MS13, special symbol processing is performed. In this special symbol process, a special symbol start process and a special symbol variation process are roughly performed. That is, in the special symbol starting process, the big hit determination random number value extracted and stored in the input process of step MS6 is compared with the set value for determination, and in the case of “big hit”, the big hit symbol extracted and stored in the input process is used. The jackpot stop symbol is determined based on the random number value, and in the case of “off”, the loss stop symbol is determined based on the values of the reach determination random number and the random symbol numbers 1, 2, and 3 for generating the offset symbol. A variation pattern is determined based on a random number value (in the embodiment, 29 types from variation pattern 1 to variation pattern 29 are set as shown in FIG. 3A), and a variation start command (design control command) Set. On the other hand, in the special symbol variation process, as shown in FIG. 3 (c), the left, right and middle special symbol designation commands (symbol control commands) corresponding to the big hit stop symbol or the outage stop symbol determined in the special symbol start processing are executed. Set sequentially. Further, a predetermined time (all symbol stop time T) until transmission of all symbol stop commands corresponding to the variation pattern determined in the special symbol start processing is set as a timer and measured. And all symbols stop command is set when predetermined time passes in this measurement result.
[0024]
When the special symbol process is completed, the process proceeds to step MS14, where the normal electric accessory opening / closing operation control is performed as the normal symbol accessory process. Next, at step MS15, as the normal symbol processing, the hit determination random number extracted and stored in the input processing at step MS6 is compared with the determination set value, and the stop symbol corresponding to the determination result is determined to control fluctuation of the normal symbol. To do. Further, in step MS16, output data of various lamps and LEDs of the lighting device 27 and the like is created as a lamp process, and in step MS17, various information signals (a big hit signal, a start winning hole entrance signal, Create a symbol confirmation signal, etc.). In Step MS18, as the surplus time random number update process, the processing program ends with the update of the initial value random number for jackpot determination, the random numbers for out symbol 1, 2, 3, the random number for reach determination, and the random number for variation pattern distribution. (Until timer interrupt processing is executed).
[0025]
That is, in the main board 34, the start winning tool 21 in the pachinko game in the game area 19 of the game board 18 while executing the above-described series of processing programs based on the timer interruption process every 2ms. If there is an incoming ball, the incoming ball detection signal from the winning switch that has detected this is input to the main board 34, and this becomes effective in the input process of step MS6 in the processing program. Then, based on the processing result of the processing program, various display commands and an INT signal are transmitted to the special symbol control board 50 in the output process of step MS5 in the processing program sequentially executed every 2 ms thereafter.
[0026]
(Special design control board)
In the special symbol control board 50, the symbol variable display is executed by executing the processing program shown in FIG. 4A every 0.5 ms by the timer interrupt processing (FIG. 4B) executed every 0.5 ms. The overall control of the device 35 is performed. Briefly describing this processing program, when the program is started, the process first proceeds to step S1 to initialize the CPU 56, etc., then proceeds to step S2 to set the stack pointer, and further proceeds to step S3 to interrupt. After the permission process, the process proceeds to step S4. If the time of proceeding to step S4 is an interrupt standby state, step S4 is repeatedly executed, and if the timer interrupt process according to FIG. 4B is executed and the interrupt standby is released, the process proceeds to step S5 and output. Execute the process. Note that the interrupt standby is set when the interrupt standby setting in step S10 is executed after the processing in steps S5 to S9.
[0027]
In the output process in step S5, a pulse output process to the motor 41 is performed based on the motor process (described later) in step S7, and each symbol display in the symbol variable display device 35 is performed based on the symbol ramp process in step S8. An output process to the illuminating device 44 installed in the design drum 42 of the unit U is performed.
[0028]
When the output process in step S5 is completed, the process proceeds to step S6 and the input process is performed. This input process is executed by receiving the display command and the INT signal transmitted from the main board 34. When the special symbol control board 50 receives the INT signal, the INT shown in FIG. Interrupt processing is executed and the INT signal flag is set. Therefore, when the display command and the INT signal are received from the main board 34, as shown in FIG. 5, in step S13, the program proceeds to step S14 to clear the INT signal flag, and then proceeds to step S15. Input processing corresponding to the display command transmitted from 34 is executed. The display commands transmitted from the main board 34 are, as described above and as shown in FIG. 3C, (1) Fluctuation start command, (2) Left special symbol designation command, (3) Right special symbol designation command, 4) There are five types of special symbol designation commands and (5) all symbol stop commands. As described later, when the command (1) is received, the change start command input process shown in FIG. 6 (a) is executed. If any of the commands (2), (3), and (4) is received, the symbol designation command input process shown in FIG. 6 (b) is executed, and the command (5) is received. If so, all symbol stop command input processing shown in FIG. 6C is executed. In the input process, when the display command and the INT signal are not received from the main board 34, the input process is terminated after executing step S13.
[0029]
The transmission interval of each display command and INT signal from the main board 34, as shown in FIG. 3 (b), starts from the time when the variation start command is transmitted, and the symbol designation command in the left column is transmitted after 2 ms. Next, a symbol designation command in the right column is transmitted 2 ms later, and a symbol designation command in the middle column is further transmitted 2 ms later. The all symbol stop command is based on the all symbol stop time T of the variation pattern set on the main board 34 side, and after the all symbol stop time T has elapsed after the variation start command is transmitted (for example, T in the case of variation pattern 1). = 9360 ms (9.36 seconds)), the data is transmitted from the main board 34.
[0030]
When the input process in step S6 is completed, the process proceeds to step S7, and the motor process shown in FIG. 7 is executed as described later. When this motor process is completed, the process proceeds to step S8, and the in-design ramp process is performed. In the in-design lamp processing, the lighting / blinking control processing of the illuminator 44 arranged in each symbol display unit U in the symbol variable display device 35 is performed, and the output is a processing program executed after 0.5 ms. In step S5. Next, the process proceeds to a random number process in step S9, and a random number process for determining a temporary stop symbol before changing again is performed. When the random number processing is completed, the process proceeds to step S10 to set an interrupt standby, and when this is completed, the process proceeds to step S4 to enter an interrupt standby state. Therefore, after the series of processing from step S5 to step S9 is completed, an interrupt standby state is entered until timer interrupt processing is executed.
[0031]
(Input processing according to the received display command)
In the “input process corresponding to the received display command” in step S15 in the input process, as described above, (1) “variation start command input process” by reception of the fluctuation start command, and (2) left special symbol designation command (3) “Design designation command input process” by receiving right special symbol designation command and (4) Medium special symbol designation command, and (5) “All symbol stop command input process” by receiving all symbol stop command are executed. .
[0032]
(Variation start command input process)
When a change start command is received, information such as which change pattern of change patterns 1 to 29 is to be executed is attached to the change start command. As shown, first, in step S16, first speed data is acquired from “variation control data” corresponding to the fluctuation pattern, and this speed data is stored in a RAM (speed). For example, FIG. 10 shows the fluctuation control data corresponding to the fluctuation pattern 1. When the fluctuation pattern 1 is set according to the processing result of the main board 34, the first speed data “−12” in the “fluctuation control data” is shown. ”And the speed data“ −12 ”is stored in the RAM (speed). When the storage of the speed data is completed, the process proceeds to step S17, where the movement amount data (number of steps) corresponding to the speed data is acquired from the “variation control data”, and this movement amount data is stored in the RAM (movement amount). Store. For example, in the case of the fluctuation pattern 1, since the movement amount data (number of steps) corresponding to the first speed data “−12” is “−5”, this movement amount data “−5” is acquired and the RAM (movement Stored in quantity). Next, the process proceeds to step S18 to set a variation flag, and then the variation start command input process is completed. The variation flag here is valid at step S25 in the motor processing shown in FIG. 7, and the variation flag is valid until step S40 is executed.
[0033]
(Design designation command input processing)
When each of the symbol designation commands is received, since the information of the final stop symbol is attached to each symbol designation command, the received symbol designation command is displayed in step S19 as shown in FIG. 6B. The symbol number is corrected and stored in the RAM (stop symbol). Here, in the symbol variable display device 35 of the embodiment, since 10 symbols in total are formed and arranged on the symbol drum 42 provided in each symbol display unit U, symbol numbers 0 to 9 are assigned to each symbol. Has been granted.

(Final stop symbol command input processing)
If all symbols stop command has been received, the process proceeds to step S20 as shown in FIG. 6C, and it is determined whether or not the RAM (speed) is waiting for a stop symbol (a shake state immediately before the final stop). Here, the data stored in the RAM (speed) includes the speed data (15, 12, 8, etc.) and the speed information ("reverse fluctuation A", "stop B" in FIG. 10, "..." E ”,... Can recognize the operating state such as“ sway H ”). In addition, there are (a) a “swing” state immediately before the final stop and (b) a “swaying” state in the middle of the fluctuation set by the fluctuation pattern. This means a “sway” state immediately before the final stop. Accordingly, if the speed information in the data stored in the RAM (speed) is in a state waiting for the final symbol due to the fluctuation just before stopping, the process proceeds to step S21, but all symbols stop command in a state that is not the shaking state immediately before stopping. When is input, the process proceeds to step S22. However, when the all symbol stop command is transmitted from the main board 34 at an appropriate timing, the special symbol control board 50 is designed so that the RAM (speed) receives the all symbol stop command in a swaying state immediately before the stop. Therefore, if there is no abnormality, the process always proceeds to step S21.
[0035]
In step S21, it is determined from the RAM (current step) and RAM (current symbol number) whether or not the current position is the stop position. In the symbol variable display device 35 of the embodiment, a RAM (current step) and a RAM (current symbol number) are provided so that the current position of each symbol display unit U can be grasped, and each symbol display unit. Each time the symbol drum 42 in U moves one step, the respective RAMs are updated. The RAM (current step) is updated by the process of step S30 described later, and the RAM (current symbol number) is updated by the process of step S32 described later. If it is determined in step S21 that the current position is the stop position, the process proceeds to step S24, and the stop symbol waiting speed information is stored in the RAM (speed). The stop symbol waiting speed information is used in steps S26 and S37 as shown in FIG. 7 and described later. On the other hand, if the current position is not the stop position, the process proceeds to step S22, as will be described later, and "final stop symbol processing" is executed.
[0036]
All symbol stop commands are received at an inappropriate timing (during fluctuation, etc.) when (a) a command is erroneously transmitted due to a failure or noise of the main board 34, or (b) operation of the symbol variable display device 35 When all symbols stop command is transmitted from the simulator system connected for the test in a timely manner, etc. are assumed. Therefore, in such a case, as will be described later, the process proceeds to step S22 and step S23 to execute "final stop symbol processing".
[0037]
(Motor processing)
Next, the motor processing in step S7 in the processing program shown in FIG. 4A will be described in detail with reference to FIG. In the symbol display control device 35 of the embodiment, the motor 41 is designed to rotate once (360 degrees) in 400 steps, and a total of ten symbols are arranged on the symbol drum 42 at equal intervals. Therefore, 40 steps of the motor 41 correspond to one symbol (36 degrees). In each symbol display unit U, the index 45 serving as a reference for detecting the position of each symbol on the symbol drum 42 is 22 in the fourth symbol (symbol number 4) from the reference position (origin position) as shown in FIG. It is formed at the pulse position (4-22).
[0038]
In the motor processing based on such premise, first, in step S25, it is determined whether or not the variation flag is valid. This variation flag is set in step S18 of the variation start command input process in FIG. 6A, and the variation start command input processing is not executed when no variation start command is received from the main board 34. The variation flag is not valid, the process of steps S26 to S41 is not performed, the motor process ends, and the motor 41 remains stopped without being driven. On the other hand, after the variation start command is received from the main board 34 and the variation start command input process is executed, the variation flag is set and valid, and the process proceeds from step S25 to step S26.
[0039]
In step S26, it is determined whether or not “0” as speed data or “waiting for stop symbol” as speed information is stored in the RAM (speed), and the speed data is “0” or the speed information is “waiting for stop symbol”. "" Proceeds to step S37. On the other hand, if the RAM (speed) is not the speed data “0” or the speed information is “waiting for stop symbol”, the process proceeds to step S27 to update the RAM (speed timer) by +1. This RAM (speed timer) is used to adjust the speed of the motor. In step S28, it is determined whether or not RAM (speed) = RAM (speed timer). If RAM (speed) = RAM (speed timer) is not satisfied, the motor processing is terminated, and RAM (speed) = RAM (speed). In the case of (timer), the process proceeds to step S29 to clear the RAM (speed timer). Here, the next steps S29 to S36 are processes for moving the motor 41 by one step, and means that the motor is moved by one step when the condition of RAM (speed) = RAM (speed timer) is satisfied. .
[0040]
Specifically, if “15” is stored as speed data in the RAM (speed), the process of step S27 is executed 15 times, so that RAM (speed) = RAM (speed timer). The program proceeds to step S29. Here, since the processing program of the special symbol control board 50 is executed every 0.5 ms, the rotation of the motor 41 is controlled by one step at 0.5 × 15 = 7.5 ms. In the speed data “15”, the rotational speed of the design drum 42 is 20 rpm. On the other hand, if “3” is stored as speed data in the RAM (speed), if the process of step S27 is performed three times, RAM (speed) = RAM (speed timer), so the program proceeds to step S29. Since the motor 41 is controlled to rotate by one step at 0.5 × 3 = 1.5 ms, the rotational speed of the symbol drum 42 is 100 rpm with this speed data “3”. That is, in the control of the embodiment, the motor 41 is rotationally controlled at a higher speed as the absolute value of the speed data is smaller.
[0041]
When the RAM (speed timer) is cleared in step S29, the process proceeds to step S30 to update the RAM (current step) by +1. This RAM (current step) is data indicating the current position in units of steps in one symbol. In the embodiment, 40 steps are equivalent to one symbol as described above, so this RAM (current step) is When the RAM (current step) is “39”, it is updated to “0”. On the other hand, a negative value of the movement amount means reverse rotation. In this case, the RAM (current step) is decremented by 1. If it is subtracted from “0”, it becomes “39”.
[0042]
In step S31, it is determined whether RAM (current step) = 0. If it is not “0”, the process proceeds to step S33, and if it is “0”, the process proceeds to step S32. In step S32, the RAM (current symbol number) is incremented by one and updated. This RAM (current symbol number) is data indicating the current position in symbol units. In the embodiment, 10 symbols are formed on the symbol drum 42 as described above, so the RAM (current symbol number) is 0 to 0. If the RAM (current step) is “9”, it is updated to “0”. Further, a negative value of the movement amount means reverse rotation. In this case, the RAM (current symbol number) is decremented by 1. In addition, when it is subtracted from “0”, it becomes “9”.
[0043]
In the next step S33, it is determined whether or not the original position switch is on. This home position switch is the detection tool 46 for detecting the index 45 provided on the design drum 41. When the detection tool 46 detects the index 45, the process proceeds to step S34, and when it is not detected. Advances to step S37. Here, in each symbol display unit U in the symbol variable display device 35 of the embodiment, the index 45 formed on the symbol drum 42 is located at the 22nd step in the symbol of symbol number 4 as described above. If the design drum 42 is not displaced due to the slip of the motor 41, the index 45 is detected by the detector 46 when the RAM (current step) is "22". Accordingly, in step S34, when the detection tool 46 detects the index 45 in step S33, "22" is set in the RAM (current step). If the RAM (current step) is other than “22”, it means that the design drum 42 is displaced, and the difference between the RAM (current step) and “22” is recognized as a displacement amount in steps. On the other hand, the RAM (current step) is forcibly rewritten to “22”. When the setting (rewriting) of the RAM (current step) is completed in step S34, the process proceeds to step S35, and the RAM (current symbol number) is set to "4" based on the detection tool 46 detecting the index 45. Even if the RAM (current symbol number) is other than “4”, the RAM (current symbol number) is forcibly set to “4”. In step S36, the RAM (excitation data) is updated. By updating the RAM (excitation data), a pulse output process to the motor 41 is performed in the output process of step S5 in FIG.
[0044]
Next, in step S37, it is determined whether or not RAM (speed) = stop symbol waiting. This RAM (speed) stores stop symbol waiting as speed information when the processing in step S24 is performed (when all symbol stop command input processing is executed) or as shown in FIG. This is after the end of the fall in the “variation control data” for final stop symbol processing. Under this condition, if “waiting for stop symbol” is stored as speed information in the RAM (speed), the process proceeds to step S39, and “waiting for stop symbol” is stored as speed information in the RAM (speed). If not, the process proceeds to step S38, and the process shown in FIG. 8 is executed as the symbol data setting process (described later).
[0045]
When the process proceeds to step S39, “Waiting for stop symbol” is stored as speed information in the RAM (speed). Therefore, the RAM (current step) updated in the process of step S30 and the process updated in step S32 are updated. It is determined whether or not the RAM (current symbol number) is the stop position set in the process of step S19. If the RAM (current step) and RAM (current symbol number) are not at the stop position, the motor processing is terminated. If the RAM (current step) and RAM (current symbol number) are at the stop position, Proceeding to step S40, the variation flag set at step S18 is cleared. That is, based on the all symbol stop command input process shown in FIG. 6C, the final stop symbol related to the variation pattern has arrived on the effective line L, and then the variation start command transmitted from the main board 34. Therefore, the design drum 42 does not change until the change flag is set in step S18.
[0046]
Then, when the process of step S40 is completed, the process proceeds to step S41, and the RAM related to fluctuation is cleared. The RAM related to the fluctuation is, for example, RAM (speed), RAM (movement amount), or the like. In this connection, the RAM (speed timer), the alignment flag, etc. are also cleared. When this processing is completed, the motor processing in the processing program ends.
[0047]
(Design data setting process)
Next, the “symbol data setting process” executed in step S38 in the motor process will be described in detail with reference to FIG. In this symbol data setting process, data for controlling the motor 41 is acquired based on the variation pattern set on the main board 34, and the data is stored in each RAM or set on the main board 34. In order to correct the symbol shift amount (to set the amount of movement) when performing the symbol alignment E executed following the high-speed D fluctuation in the fluctuation pattern in order to stop and display the final stop symbol on the active line L. Are acquired and stored in the RAM. In the symbol alignment in the present embodiment, the alignment process based on time, in other words, the symbol drum 42 is rotated and moved at a plurality of alignment speeds (two types in the embodiment), so that it is always in a fixed time. It is characterized by correcting the shift amount of symbols. Specifically, taking the variation pattern 1 shown in FIG. 11 as an example, (a) “symbol position correction” processing executed for 2.4 seconds (4,800 rst), and (b) 0.24 seconds ( 480 rst) and the “step position correction” process, the design drum 42 is moved to the first alignment speed S₁And the second alignment speed S₂By rotating and moving at, it is always set to complete the alignment E process in a total of 2.64 seconds (5,280 rst).
[0048]
(Design position correction method)
In the symbol drum 42 of this embodiment, as described above, a total of ten symbols are arranged at equal intervals, so that the symbol displayed on the effective line L before the symbol alignment process and the symbol variation stop There are always 10 possible deviations from the final stop symbol displayed on the effective line L later. For example, when the display symbol before the symbol alignment process and the final stop symbol are the same symbol, the deviation amount is the smallest (no deviation at all), and the symbol drum 42 of the symbol drum 42 with respect to the display symbol before the symbol alignment. When the symbol adjacent in the rotation direction is the final stop symbol, the amount of deviation is the largest (for nine symbols). The “symbol position correction” method of the embodiment based on this premise is the first alignment speed S set to speed 3 in order to correct all the shift amounts within a fixed time of 2.4 seconds.₁And / or second alignment speed S set to speed 4₂The first alignment speed S₁Variation time and second alignment speed S₂By changing the ratio with the fluctuation time at, the amount of movement corresponding to the above-mentioned 10 kinds of deviations can be set. FIG. 11A shows symbol position correction data consisting of a total of ten types of position correction patterns Q set in advance based on this, and the first symbol position correction movement amount data MD.₁The design drum 42 is moved to the first alignment speed S₁Indicates the amount of movement obtained by rotational movement over the required time, and the second symbol position correction movement amount data MD₂The design drum 42 is moved to the second alignment speed S₂The movement amount obtained by rotating and moving over the required time is shown.
[0049]
For example, the No. 1 position correction pattern Q is the second symbol position correction movement amount data MD.₂No. “30”, and the design drum 42 is moved to the second alignment speed S.₂Rotate for 2.4 seconds (4,800 rst) and move for 30 symbols (3 rotations). The amount of movement for 2.4 seconds is the shortest and the same symbol before and after the symbol alignment process as described above. This is selected when stopping display. The position correction pattern Q of No. 10 is the first symbol position correction movement amount data MD.₁"36" and second symbol position correction movement amount data MD₂And the design drum 42 is moved to the first alignment speed S.₁Rotate for 2.16 seconds (4,320 rst) to move 36 symbols, and the second alignment speed S₂Rotate for 0.24 seconds (480 rst) and move 3 symbols, and the amount of movement in 2.4 seconds (4,800 rst) is 39 symbols (the longest), so 9 symbols from No. 1 Longest longest. Furthermore, the position correction pattern Q of No. 4 is the first symbol position correction movement amount data MD.₁"12" and the second symbol position correction movement amount data MD₂The design drum 42 is moved to the first alignment speed S.₁Rotate for 0.72 seconds (1,440 rst) to move 12 symbols, and the second alignment speed S₂In this case, 21 symbols are moved by rotating for 1.68 seconds (3,360 rst), and the movement amount for 2.4 seconds (4,800 rst) is 33 symbols (3 rotations + 3 symbols). In such a symbol position correction method, a shift amount (movement amount) is calculated from a display symbol before symbol alignment processing and a final stop symbol after symbol variation stop, and the position correction pattern Q of No. 1 to No. 10 is calculated. The one corresponding to the calculation result is acquired from among the symbols, and thereby the symbols can be always aligned in a fixed time of 2.4 seconds (4,800 rst).
[0050]
(Step position correction method)
Further, the “step position correction” method is for correcting a subtle deviation in the step unit of the display symbol caused by a slip or the like that may occur in the motor 41. As described above, a fixed time of 0.24 seconds. It is supposed to be done in. As described above, a total of 10 symbols are arranged at equal intervals on the symbol drum 42 of each symbol display unit U in the symbol variable display device 35 of the embodiment, and 40 steps of the motor 41 correspond to one symbol. Since it corresponds to (36 degrees), there are 40 possible errors in step units within one symbol. The “step position correction” method of the embodiment on the premise of this is that the first alignment speed S set to speed 3 in order to correct all the deviation amounts within a fixed time of 0.24 seconds.₁And / or second alignment speed S set to speed 4₂The first alignment speed S₁Variation time and second alignment speed S₂By changing the ratio with the fluctuation time at, the movement amount corresponding to the 40 deviation amounts can be set. FIG. 11 (b) shows step position correction data composed of a total of 40 types of position correction patterns R set in advance based on this, and the first step position correction movement amount data SD.₁The design drum 42 is moved to the first alignment speed S₁Indicates the amount of movement obtained by rotational movement over the required time, and the second step position correction movement amount data SD₂The design drum 42 is moved to the second alignment speed S₂The movement amount obtained by rotating and moving over the required time is shown.
[0051]
For example, the position correction pattern R of No. 1 is the first step position correction movement amount data SD.₁No. “160” and the design drum 42 is moved to the first alignment speed S₂This is selected when there is no shift in the pattern due to the slip of the motor 41, which is rotated for 160 steps (4 patterns) by rotating for 0.24 seconds (480 rst). The position correction pattern R of No. 40 is the first step position correction movement amount data SD.₁"4" and second step position correction movement amount data SD₂Of "117", and the design drum 42 is moved to the first alignment speed S.₁Rotate for 0.006 seconds (12rst) and move 4 steps, and the second alignment speed S₂Rotate for 0.234 seconds (468 rst) and move 117 steps. The movement amount for 0.24 seconds (480 rst) is 121 steps (3 steps + 1 step). It is selected when the amount is the maximum 39 steps. Further, the position correction pattern R of No. 20 is the first step position correction movement amount data SD.₁"84" and second step position correction movement amount data SD₂The design drum 42 is moved to the first alignment speed S.₁Rotate for 0.126 seconds (252 rst) and move 84 steps, the second alignment speed S₂Rotate for 0.114 seconds (228 rst) and move 57 steps. The movement amount for 0.24 seconds (480 rst) is 141 steps (3 symbols + 21 steps). Is selected when there are 19 steps. In such a step position correction method, the sum of the shift amount and the correction amount is always 4 symbols (160 steps).
[0052]
As described above, in the “symbol data setting process” for setting the data used for “symbol position correction” and “step position correction”, first in step S42, the above-described step S17 or steps S45, S51, and S57 described later are performed. It is determined whether or not the value of RAM (movement amount) stored in any of the above and subtracted in step S53 described later is “0”. If the RAM (movement amount) is “0”, the process proceeds to step S43. If (movement amount) is not “0”, the process proceeds to step S53. That is, from the “variation control data” shown in FIG. 10, speed data is sequentially stored in the RAM (speed) and movement amount data (number of steps) is sequentially stored in the RAM (movement amount). If the movement amount at is not achieved, the process proceeds to step S53. If the movement amount at that speed is achieved, the process proceeds to step S43.
[0053]
In step S43, it is determined whether or not the “alignment flag” set in step S52, which will be described later, is valid. If the alignment flag is set, the process proceeds to step S58, and the alignment flag is not set. Advances to step S44. That is, in the variation pattern, if the “alignment E” shown in FIG. 9 is currently being performed, the alignment flag should have been set in step S52, and the process proceeds to step S58, where the current “alignment E” is performed. If not, the alignment flag should be cleared in step S60, and the process proceeds to step S44.
[0054]
When the process proceeds to step S44, the movement amount at the current speed is achieved from the determination in step S42, and the current position is not “alignment” from the determination in step S43. The next speed data is acquired from the “data” and stored in the RAM (speed). As an example, in the fluctuation pattern 1 shown in FIG. 10, it was after storing the first speed data “−12” shown in the fluctuation speed in the “variation control data” shown in FIG. If this is the case, the next speed data “−8” is acquired and stored in the RAM (speed). Next, in step S45, movement amount data (number of steps) corresponding to the speed data acquired in step S44 is acquired from the “variation control data” and stored in the RAM (movement amount). In the variation pattern 1, as shown in FIG. 10, the movement amount data “−10” corresponding to the speed data “−8” is acquired and stored in the RAM (movement amount).
[0055]
Next, in step S46, if “alignment” is stored in the speed information of the speed data stored in the RAM (speed) in step S44, the process proceeds to step S47, and “positioning” is performed in steps S47 to S49. If “position alignment” is not stored in the speed information of the speed data, the symbol data setting process is completed.
[0056]
(Selection of position correction pattern for step position correction)
In step S47, a position correction pattern R for the “step position correction” process for correcting the shift amount in steps of one symbol is selected. In other words, in the motor processing, the degree of deviation of the RAM (current step) with respect to “0” is calculated. Based on the calculation result, the step position correction data shown in FIG. The position correction pattern R is determined, and the first step position correction movement amount data SD of the position correction pattern R is determined.₁And second step position correction movement amount data SD₂Are stored in RAM (first alignment movement amount) and RAM (second alignment movement amount). Here, for example, as shown in part (b) of FIG. 13, when the RAM (current step) is shifted by “3” steps, the shift is caused by moving 3 symbols +37 steps in the rotation direction of the symbol drum 42. Since the correction is performed, the No. 4 position correction pattern R in the step position correction data of FIG. 11B is selected, and the first step position correction movement amount data SD is selected.₁"148" and second step position correction movement amount data SD₂"9" is acquired, and each data is stored in RAM (first alignment movement amount) and RAM (second alignment movement amount).
[0057]
When the process of step S47 is completed, the process proceeds to step S48, and the symbol information data at the end of alignment is acquired. For example, in the variation pattern 1 shown in FIGS. 9 and 10, a total of three symbols are moved by combining two symbols (80 steps) at the fall F performed after the alignment E and one symbol at the medium speed G. Therefore, the symbol at the end of alignment is the symbol three symbols before the last stop symbol, and symbol information data corresponding to this symbol is acquired.
[0058]
(Position correction pattern selection for symbol position correction)
In step S49, a position correction pattern Q is selected for the "symbol position correction" process for correcting the shift in accordance with the shift amount in symbol units. That is, the RAM (current symbol number) is calculated how much it deviates from the symbol information data obtained at the end of alignment acquired in step S48, and based on the calculation result, “ From the “design position correction data”, the first alignment speed S₁1st symbol position correction movement amount data MD₁And the second alignment speed S₂2nd symbol position correction movement amount data MD₂And the respective data are added to and stored in the RAM (first alignment movement amount) and the RAM (second alignment movement amount). For example, if there is a deviation of 2 symbols between the symbol information data acquired in step S48 and the RAM (current symbol number), it is determined that 10 symbols are formed on the outer peripheral surface of the symbol drum 42. In view of this, if the symbol drum 42 is moved in the rotation direction by n rounds + 8 symbols, the deviation is corrected. However, since the movement amount data for 4 symbols is stored in the “step position correction” process in step S47, it is only necessary to move n cycles + 4 symbols here. Therefore, the No. 5 position correction pattern Q in the “symbol position correction data” of FIG. 11A is selected, and the first symbol position correction movement amount data MD is selected.₁"16 symbols (640 steps)" and second symbol position correction movement amount data MD₂“18 symbols (step 720)” are acquired, and the respective data are stored in RAM (first alignment movement amount) and RAM (second alignment movement amount). As a result, 148 + 640 = 788 is stored in the RAM (first alignment movement amount), and 9 + 720 = 729 is stored in the RAM (second alignment movement amount).
[0059]
As described above, in the present embodiment, the data for the “step position correction” process and the “symbol position correction” process is set by the processing of step S47 to step S49, and the deviation in step units and the deviation in symbol units are suitably performed. It will be corrected. Such symbol alignment is performed by the first alignment speed S.₁(Speed 3) and / or second alignment speed S₂Due to the rotational movement of the symbol drum 42 at (speed 4), the processing is always completed in 2.64 seconds (5280 rst) regardless of the combination of any position correction patterns Q and R.
[0060]
Next, in step S50, the first alignment speed S is stored in the RAM (speed).₁Is stored. In the symbol variable display device 35 of the embodiment, the first alignment speed S₁However, since the speed is 3 as described above, “3” is stored in the RAM (speed). In step S51, the RAM (first alignment movement amount) acquired in step S49 is stored in the RAM (movement amount) (“788” in the above example). In step S52, an alignment flag that is valid in step S43 is set.
[0061]
In step S47 to step S49, data for “step position correction” and “symbol position correction” is set, and then in step S50, the first alignment speed S is stored in the RAM (speed).₁(Speed 3) is stored, the first alignment movement amount is stored in the RAM (movement amount) in step S51, and the process proceeds to step S42 in the next processing program with the alignment flag set in step S52. Then, since it is determined that RAM (movement amount) ≠ 0 based on the first alignment movement amount stored in step S51, the process proceeds to step S53, and RAM (movement amount) is subtracted. That is, the process proceeds from step S42 to step S53 until the data stored in step S51 becomes RAM (movement amount) = “0” in step S53.
[0062]
On the other hand, when “N” is selected in step S20 in the all symbol stop command input process shown in FIG. 6 (c) and the processes in steps S22 and S23 are performed (all symbol stop commands are received during the change). In the case), a “final stop symbol process” is performed as will be described later, and a “matching symbol wait” process is performed during the final stop symbol process. That is, in step S54, it is determined whether or not the speed information in the RAM (speed) is “waiting for a matching symbol” in the final stop symbol processing. If “waiting for a matching symbol”, the process proceeds to step S55, and “waiting for a matching symbol”. If not, the symbol data setting process is terminated. Steps S55 to S57 are related to “final stop symbol processing” to be described later, and thus the description thereof is omitted here.
[0063]
If the RAM (movement amount) set in step S51 becomes “0” by the processing in step S53 due to the flow of step S42 → step S53 in each processing program, the next processing program The process proceeds from step S42 and step S43 to step S58. That is, RAM (movement amount) = 0 means that the first alignment speed S₁Since the movement amount by (speed 3) has been achieved, the second alignment speed S is determined in step S58.₂Store (speed 4) in RAM (speed). In step S59, the first alignment speed S₁Since the movement amount by (speed 3) has been achieved, RAM (second alignment movement amount) is stored in RAM (movement amount). Further, in step S60, since the speed and movement amount data relating to the alignment are stored in the respective RAMs in steps S58 and S59, the alignment flag set in step S52 is cleared.
[0064]
Thus, in the subsequent processing program, the process proceeds from step S42 to step S53, and the RAM (movement amount) set in step S59 is subtracted every time, and when the RAM (movement amount) becomes “0”, step S43 is executed. Proceed to The fact that RAM (movement amount) = 0 here means that the second alignment speed S₂Since the movement amount by (speed 4) has been achieved, this means that the symbol alignment process in the fluctuation pattern has been completed.
[0065]
(Final stop symbol processing)
Next, it is executed when an all symbols stop command transmitted from the main board 34 is received at an inappropriate timing, or when an all symbols stop command transmitted from the simulator system is received for shortening the operation test time. The “final stop symbol processing” will be described. As described above, when all symbol stop commands are received at an inappropriate timing in the variation pattern, if the reception timing is not waiting for a stop symbol (a shake state immediately before the final stop), the process proceeds to step S22. . If all symbols stop command is received in the stop symbol waiting state, the process proceeds from step S20 to step S21, but if the current position is not at the stop position, the process proceeds to step S22.
[0066]
In step S22, speed data is acquired from the “variation control data” for final stop symbol processing shown in FIG. 12, and this data is stored in RAM (speed). However, since it is not determined at which operation shown in FIGS. 9 and 10 all the symbol stop commands are received, the “variation control data” for the final stop symbol processing is the motor 41 executing the operation. Four types (a) to (d) of FIG. 12 are prepared in accordance with the speed of one of these, and one of these is selected. For example, when the all symbols stop command is received during the medium speed G processing and the final stop symbol processing is performed, the speed is “12”, so the “variation control data” in FIG. The first fluctuation data “15” and speed information “rise” are acquired and stored in the RAM (speed). Next, in step S23, movement amount data (number of steps) “3” is acquired and stored in the RAM (movement amount) based on the “variation control data” of FIG. 12A selected in step S22. .
[0067]
Then, after the processing of step S22 and step S23 is performed and the input processing is completed, the processing proceeds to the symbol data setting processing of step S38 in the motor processing, and the processing proceeds from step S42 to step S53 to perform the subtraction processing of RAM (movement amount). Then, the process proceeds to step S54. In this step S54, it is determined whether or not the RAM (speed) is “waiting for a matching symbol” (when all symbols stop command is received in the middle of fluctuation), and if it is not “waiting for a matching symbol” (“rise” or “starting”). In the case of “decrease”), the symbol data setting process is terminated, and in the case of “waiting for a matching symbol”, the processing program proceeds to step S55. Note that “waiting for a matching symbol” is a process of moving until the current position (RAM (current step) and RAM (current symbol number)) matches the stop position (one symbol before the stop symbol).
[0068]
In step S55, it is determined whether the current position (RAM (current step) and RAM (current symbol number)) is a stop position (one symbol before the last stop symbol). If the current position is the stop position, the process proceeds to step S56. If the current position is not the stop position, the symbol data setting process is terminated. If the current position is the stop position, the next speed data is acquired from the “variation control data” (FIG. 12) for final stop symbol processing in step S56, and this data is stored in the RAM (speed). . In addition, after “waiting for a matching symbol” in the final stop symbol processing, any of the data (a) to (d) is always “falling”, so here the first speed data “6” of “falling” is “6”. ”Is acquired, and this speed data is stored in the RAM (speed). Next, in step S57, movement amount data (number of steps) “10” corresponding to the first speed data in “falling” is acquired, and this data is stored in the RAM (movement amount).
[0069]
In the final stop symbol processing based on such a processing program, for example, when an all symbol stop command is received from the simulator system, after performing all symbol stop command input processing steps S22 and S23 in the input processing, In the symbol data setting process in step S38, step S42 → step S53 to step S54 are repeated in the “start-up” process of “variation control data” for the final stop symbol process shown in FIG. 12, and RAM (movement amount) = 0. Then, acceleration control of the motor 41 is performed by executing steps S42 to S46. When the “start-up” process is completed, the process proceeds from step S42 to step 43 and step S44 as RAM (movement amount) = 0, and in this step S44, the speed data “3” for waiting for the matching symbol is displayed. ”And after storing this data in the RAM (speed), the process proceeds to step S45. Here, the amount of deviation between the display symbol before the matching symbol waiting process and the symbol one symbol before the last stop symbol is not constant, and the amount of deviation is from a minimum of one step to a maximum of 400 steps (one rotation). Therefore, since the movement amount data (step) is not determined, 400 or more (for example, 500) is acquired as movement amount data for the time being in step S45, and the 400 or more data is stored in the RAM (movement amount). To do.
[0070]
As a result, in the subsequent processing program, the process proceeds from step S42 to step S53 and step S54, and further proceeds to step S55. By repeating this, the current state is changed before the RAM (movement amount) becomes “0”. The condition of the stop position (one symbol before the final stop symbol) is established, the process proceeds from step S55 to step S56 and step S57, and proceeds to the “falling” process. That is, if the movement amount data is set to 400 or more, the stop position always comes while the symbol drum 42 makes one rotation. In the “falling” process, step S42 → step S53 to step S54 are repeated, and when RAM (movement amount) = 0, step S42 to step S46 are executed to control the motor 41 to decelerate.
[0071]
At the time when the “falling” process is completed, the process proceeds from step S42 to step S43 and step S44 as RAM (movement amount) = 0. As a stop process, the speed data is “ “0” is acquired, and “waiting for stop symbol” is stored in the RAM (speed) as this data and speed information. In step S45, the movement amount data “0” is stored in the RAM (movement amount), and then step S46 is executed to complete the symbol data setting process. As a result, in the motor processing in the next processing program, the process proceeds from step S25 to step S26, and since RAM (speed) = stop symbol waiting, the process proceeds from step S26 to step S37, and further from step S37 to step S39. In step S40 and step S41, the motor process is terminated and the motor 41 is controlled to stop.
[0072]
[Effect of the embodiment]
Next, the main symbol 34 for executing the processing program shown in FIG. 2 every 2 ms and the special symbol control board 50 for executing the processing program shown in FIG. A case where the symbol variation control in the device 35 is performed will be described. In the symbol variable display device 35, each symbol display unit in three columns is based on a total of 29 kinds of variation patterns (FIG. 3A) determined in the special symbol processing (step MS13 in FIG. 2) on the main board 34. Each U is driven and controlled, so that it is possible to perform symbol variation control related to symbol variation and symbol stop which are rich in change and high grade. Therefore, here, the symbol display control when the variation pattern 1 is set in the special symbol processing on the main board 34 will be described. As shown in FIG. 9, the fluctuation pattern 1 is obtained by changing the three symbol display units U to reverse fluctuation A → stop B → rise C → high speed D → alignment E → fall F → medium speed G → sway. This is executed in the order of H, and the symbol variation control constituted by such a series of operations is performed in one cycle 9360 ms (9.36 seconds).
[0073]
(Detection of winning ball and determination of fluctuation pattern)
First, in a pachinko game in the game area 19 of the game board 18 of the pachinko machine P, when a game ball launched into the game area 19 enters the start prize tool 21, the start prize tool 21 A ball detection signal is input from the winning switch to the main board 34. As a result, the main board 34 extracts the big hit determination random number and the big hit symbol random number by the input process in step MS6 as described above and stores them in the RAM. To do. In the main board 34, in the special symbol start process in the special symbol process in step MS13, the big hit determination random number value extracted and stored in the input process in step MS6 is compared and determined in advance. When the determination result is “big hit”, the big hit stop symbol is determined based on the big hit symbol random number, and when the determination result is “out”, the loss stop symbol is determined. Further, for example, the variation pattern 1 is determined from the 29 types of variation patterns based on the value of the variation pattern distribution random number. Based on this result, a change start command (symbol control command) corresponding to the change pattern 1 is created in the information processing of step MS17 (FIG. 3C). The variation start command created by the main board 34 is transmitted to the special symbol control board 50 in the output process of step MS5 in the next program executed 2 ms after the program.
[0074]
In addition, special symbol designation commands (symbol control commands) for the left column, right column, and middle column corresponding to the big hit stop symbol or miss stop symbol determined in the special symbol start process are sequentially created, and are shown in FIG. As described above, a special symbol designation command for the left column is first transmitted 2 ms after the transmission of the fluctuation start command, a special symbol designation command for the right column is transmitted after 2 ms, and a special symbol designation for the middle column is further transmitted 2 ms later. A command is sent. In addition, since the total symbol stop time T of the variation pattern 1 determined in the special symbol start process is 9360 ms, the time until transmission of all symbol stop commands corresponding to the total symbol stop time T is set as a timer to start measurement. When the time is up, all symbol stop commands are created and transmitted.
[0075]
(Variation start command input process)
On the other hand, when the special symbol control board 50 receives the fluctuation start command first transmitted from the main board 34, as shown in FIGS. 5 and 6A, as the fluctuation start command input process in the input process of step S6. The speed data “−12” is acquired from the “variation control data” corresponding to the fluctuation pattern 1 shown in FIG. 10 and stored in the RAM (speed), while the movement amount data corresponding to the speed data (step S17). Number) After obtaining “−5” and storing it in the RAM (movement amount), the fluctuation flag is set in step S18.
[0076]
(Design designation command input processing)
On the other hand, when the left column designating command transmitted from the main board 34 is received 2 ms after the change start command transmission, as shown in FIGS. 5 and 6B, the left column design designating command input process in the input process of step S6. The received symbol designation command is corrected to the symbol number and stored in the RAM (stop symbol). When the right column design designation command transmitted from the main board 34 is received after 2 ms, the received right column design designation command is corrected to the symbol number as the right column design designation command input process in the input process of step S6. Store in RAM (stop symbol). Further, when the middle row symbol designation command transmitted from the main board 34 is received after 2 ms, the received middle row symbol designation command is corrected to the symbol number as the middle row symbol designation command input process in the input process of step S6. Store in RAM (stop symbol).
[0077]
(Reverse fluctuation A)
In the motor process of step S7 based on the above-described change start command input process, the motor process ends after executing steps S25 to S28. Each time the processing program of FIG. 4 is executed every 0.5 ms, the RAM (speed timer) is updated in step S27. When this processing program is executed 12 times, RAM (speed) = RAM (speed timer). Therefore, the process proceeds from step S28 to step S29, the RAM (current step) is updated in step S30, the motor 41 is controlled to rotate in the reverse direction by one step, and the RAM (movement amount is changed in step S53 in the symbol data setting process). ) Is subtracted. Accordingly, in the reverse variation A, first, as a first step, the processing program is executed 12 × 5 = 60 times, and during this time, the design drum 42 is rotated and moved in the reverse direction by 5 steps. At this time, the RAM (movement amount) becomes 0 by the processing in step S53, so the next speed data “−8” is acquired and stored in the RAM (speed) in step S44 and the next speed data in step S45. The movement amount data “−10” is acquired and stored in the RAM (movement amount). Therefore, in the second stage of reverse fluctuation A, the processing program is executed 8 × 10 = 80 times, and during this time, the design drum 42 is further rotated in the reverse direction by 10 steps. Since the RAM (movement amount) becomes 0 by the processing in step S53, the next speed data “−12” is acquired and stored in the RAM (speed) in step S44, and the next movement amount data is obtained in step S45. “−5” is acquired and stored in the RAM (movement amount). Thus, in the third stage of the reverse fluctuation A, the processing program is executed 12 × 5 = 60 times, and during this time, the symbol drum 42 is further rotated in the reverse direction by 5 steps. That is, in the reverse variation A, the design drum 42 is rotated in the reverse direction by 20 steps (0.5 symbols) in 0.1 seconds by executing the processing program of FIG. 4 a total of 200 times.
[0078]
(Stop B)
When the processing program proceeds to step S44 when the above-mentioned "reverse fluctuation A" is completed, "0" is acquired as the next speed data and "stop" is obtained as the speed information from the "variation control data" of the fluctuation pattern 1. This data is stored in the RAM (speed), and “0” is stored in the RAM (movement amount) as the movement amount data in step S45. However, in this stop B, the reset number “960” is stored as the speed data, and the symbol drum 42 is stopped for 0.48 seconds.
[0079]
(Start-up C)
When the processing program proceeds to step S44 when the above-mentioned “stop B” ends, “15” as the next speed data and “rise” as the speed information are acquired from the “variation control data” of the fluctuation pattern 1. This data is stored in the RAM (speed), and “3” is stored in the RAM (movement amount) as movement amount data in step S45. In this start-up C, 3 steps at speed 15 (first stage), 5 steps at speed 12 (second stage), 7 steps at speed 8 (third stage), 6 steps at speed 6 (fourth stage), While moving 60 steps (0.1 symbols) in 0.18 seconds, 7 steps (5th step) at speed 5 and 32 steps (6th step) at speed 4, the design drum 42 is changed to 6 steps. Separately and gradually accelerate to speed 4.
[0080]
(High speed D)
When the processing program proceeds to step S44 when the above-described "start-up C" is completed, "3" as the next speed data and "high speed" as the speed information are acquired from the "variation control data" of the fluctuation pattern 1. This data is stored in the RAM (speed), and “2320 (58 symbols)” is stored in the RAM (movement amount) as movement amount data in step S45. Accordingly, at the high speed D, the design drum 42 is rotated at a constant speed for 3.48 seconds at a speed of 3 (100 rpm) while executing the processing program 3 × 2320 = 6960 times, thereby moving 2320 steps (58 designs). .
[0081]
(Alignment E)
When the processing program proceeds to step S44 when the above-described “high-speed D” is completed, “position alignment” is acquired from the “variation control data” of the variation pattern 1 as the velocity information of the next velocity data, and this data is stored in the RAM. Store in (speed). That is, since the speed and the moving amount as the speed data have not yet been determined at the time of entering the alignment E process, only the alignment is stored as the speed information at this time. As a result, the process proceeds from step S46 to step S47, so that the processes of steps S47 to S52 are executed.
Here,
RAM (current step) = 5
RAM (current symbol number) = 8
Symbol information data = 4
Final stop symbol = 7
It is assumed that
[0082]
(Data setting for step position correction processing)
First, in step S47, for the “step position correction” process, the design drum 42 is moved to 3 by recognizing that the RAM (current step) is shifted from “0” by 5 steps from the motor process of FIG. It is calculated that the shift is corrected in increments of steps by moving the pattern +35 steps (155 steps), and the position correction pattern R of No. 6 in the step position correction data shown in FIG. 11B is selected. . Thus, the first step position correction movement amount data SD₁"140" and second step position correction movement amount data SD₂"15" is acquired, and the respective data are stored in the RAM (first alignment movement amount) and the RAM (second alignment movement amount). And after performing the process of step S48 and acquiring symbol information data "4", the process of step S49 is performed.
[0083]
(Data setting for symbol position correction processing)
In this step S49, for the “symbol position correction” process, the RAM (current symbol number) is compared with the symbol information data acquired in step S48, and it is recognized that there is a shift of 8-4 = 4 symbols. Under the circumstances, it is recognized that the shift of the symbol unit is corrected by moving the symbol by 3 rotations + 6 symbols. However, since the movement amount data for 4 symbols has already been stored in step S47, it is actually necessary to subtract 4 symbols and move by 3 rotations + 2 symbols (32 symbols). The No. 3 position correction pattern Q in the “symbol position correction data” shown in a) is selected. Thereby, the first symbol position correction movement amount data MD₁"8 symbols (320 steps)" and second symbol position correction movement amount data MD₂"24 symbols (960 steps)" are acquired, and each data is added to the RAM (first alignment movement amount) and the RAM (second alignment movement amount) and stored. Thereby, 140 + 320 = 460 is stored in the RAM (first alignment movement amount), and 15 + 960 = 975 is stored in the RAM (second alignment movement amount).
[0084]
When the storage of data associated with the alignment E is completed in steps S47 to S49, the first alignment speed S is stored in the RAM (speed) in step S50.₁“3” is stored, and “460” is stored as the first alignment movement amount in the RAM (movement amount) in step S51. Thus, in the first stage of the alignment E process, the processing program is executed 3 × 460 = 1380 times, so that RAM (movement amount) = 0, so that the process proceeds from step S42 to step S43 and to step S58. become. In step S58, the second alignment speed S is stored in the RAM (speed).₁“4” is stored, and “975” is stored as the second alignment movement amount in the RAM (movement amount) in step S59. Thus, in the second stage of the alignment E process, the processing program is executed 4 × 975 = 3900 times, so that RAM (movement amount) = 0, and the symbol alignment process is completed. At the time when the alignment E is completed, the symbol three symbols before the final stop symbol (the symbol of symbol number 4) is positioned on the effective line L.
[0085]
(Falling F)
When the processing program proceeds to step S44 when the above-mentioned "positioning E" is completed, "6" as the next speed data and "fall" as the speed information are acquired from the "variation control data" of the fluctuation pattern 1. The data is stored in the RAM (speed), and “10” is stored in the RAM (movement amount) as the movement amount data in step S45. In this start-up C, 80 steps (2 steps) in 0.32 seconds, such as 10 steps (first stage) at speed 6, 65 steps (second stage) at speed 8, 5 steps (third stage) at speed 12, and so on. During this time, the design drum 42 is divided into three stages and gradually decelerated to a speed of 12. That is, at the time when the fall F is completed, the symbol immediately before the final stop symbol (the symbol of symbol number 6) has arrived on the active line L.
[0086]
(Medium speed G)
When the processing program proceeds to step S44 when the above-described "falling F" is completed, "12" as the next speed data and "medium speed" as the speed information are acquired from the "variation control data" of the fluctuation pattern 1. This data is stored in the RAM (speed), and “40 (one symbol)” is stored in the RAM (movement amount) as movement amount data in step S45. At this medium speed G, the design drum 42 is rotated at a constant speed for 0.24 seconds at a speed of 12 while executing the processing program 480 times, thereby moving 40 steps (one symbol). That is, when the medium speed G is completed, the final stop symbol (the symbol of symbol number 7) has arrived on the active line L.
[0087]
(Yure H)
When the processing program proceeds to step S44 when the above-described “medium speed G” is completed, “sway” is acquired as the next speed information from the “variation control data” of the fluctuation pattern 1, and this data is stored in the RAM (speed). In step S45, “6 reciprocations” is stored in the RAM (movement amount) as movement amount data. That is, in this shake H, a slight vibration of 6 reciprocations is performed over 1.92 seconds, and it is visually recognized by the player as if the final stop symbol is stopped on the effective line L. Actually, it does not stop completely by slightly vibrating up and down, which means that the symbol variation is continuing.
[0088]
The variation pattern 1 shown in the embodiment is for variation control with respect to the symbol display units U in the left column as shown in FIG. 9, and the variation control for the symbol display units U in the right column and the middle column is performed for all symbols. On the premise that the stop times T are all 9.36 seconds and controlled so as to be sequentially stopped with an appropriate time difference with respect to the left column, the time of the high-speed D is lengthened appropriately, and based on this The other operations are the same as those in the left column. By the way, in the left column, high speed D (D₁) Operation time 3.48 seconds, swing H (H₁) Operation time is 1.92 seconds, while in the right column, high-speed D (D₂) Operation time 3.96 seconds, swing H (H₂) Operation time is 1.44 seconds, and in the middle row, high-speed D (D_Three) Operation time of 4.44 seconds, swing H (H_Three) Operation time is 0.96 seconds.
[0089]
(Final stop symbol processing)
Further, when the all symbol stop command is transmitted from the main board 34 during the symbol variation, or when the all symbol stop command is transmitted from the simulator system in a timely manner, the steps S22 and S23 in the all symbol stop command input process in the input process. Then, the final stop symbol processing is executed. For example, when all symbol stop commands are received during the high-speed D process, the speed is “3”. Therefore, in the step S22, the data (d) in the variation control data for the final stop symbol process shown in FIG. Is selected, speed data “4” and “startup” are acquired as speed information and stored in the RAM (speed), and movement amount data “60” is acquired in step S23 to obtain the RAM (movement amount). ). However, when the all symbols stop command is received at the high speed D, the fluctuation speed is actually reduced to “4” by the start-up.
[0090]
(Waiting for matching symbols)
When the above-described “start-up” is completed, the process proceeds from step S42 to step 43 and step S44 as RAM (movement amount) = 0. In this step S44, the speed data “3” for waiting for the matching symbol is stored. For example, “500” is acquired as temporary movement amount data and stored in the RAM (movement amount) in step S45. As a result, the current stop position (one symbol before the final stop symbol) is established before the RAM (movement amount) becomes “0”, and the process proceeds from step 55 to step S56 and step S57 to “fall”. Proceed to processing.
[0091]
(Fall)
When the symbol immediately before the final stop symbol arrives on the effective line L and the processing program proceeds to step S56, “6” is set as speed information from “variation control data” of the final stop symbol processing as the next speed data. The “fall” is acquired and this data is stored in the RAM (speed), and “10” is stored in the RAM (movement amount) as the movement amount data in step S57. In this fall, 10 steps (first stage) at speed 6, 25 steps (second stage) at speed 8, 5 steps (third stage) at speed 12, and 40 steps (one pattern) are moved. In the meantime, the design drum 42 is gradually decelerated to the speed 12 in three stages. That is, when the fall is completed, the final stop symbol has arrived on the active line L.
[0092]
After the completion of the fall and the processing program proceeds to step S44, “waiting for stop symbol” is acquired as the next speed information from the “variation control data” of the final stop symbol processing and stored in the RAM (speed). In step S45, the movement amount data “0” is stored in the RAM (movement amount), so that the motor 41 is controlled to stop in a state where the final stop symbol is stopped and displayed on the effective line L.
[0093]
As described above, in the symbol alignment according to the present embodiment, the “step position correction” process can be performed in a fixed time of 0.24 seconds to correct the step-by-step deviation. Therefore, a total of 40 types of position correction patterns R If only the step position correction data (FIG. 11 (b)) consisting of is set, all the step position correction processes are suitably performed. Therefore, the step position correction data can be greatly reduced. Moreover, the first alignment speed S that is the same speed as the fluctuation speed at the high speed D.₁(Speed 3) and / or the second alignment speed S at substantially the same speed₂Since step position correction is performed at (speed 4), the processing time associated with symbol alignment is shortened, while unnatural symbol fluctuations during step position correction processing do not occur, and the player can It is difficult to realize that it is an action.
[0094]
Further, in the symbol alignment of this embodiment, since the symbol deviation can be corrected by performing the “symbol position correction” process in a fixed time of 2.4 seconds, the pattern correction pattern Q is composed of a total of ten types of position correction patterns Q. If only symbol position correction data (FIG. 11 (a)) is set, all symbol position correction processing is suitably performed. Therefore, the symbol position correction data can be greatly reduced. Moreover, the first alignment speed S that is the same speed as the fluctuation speed at the high speed D.₁(Speed 3) and / or the second alignment speed S at substantially the same speed₂Since the symbol position correction is executed at (speed 4), the processing time associated with the alignment is shortened, while the unnatural symbol variation during the symbol position correction process does not occur, and the player can perform the symbol alignment. It is difficult to realize that it is an action.
[0095]
In addition, since the symbol position correction process and the step position correction process are executed by the special symbol control board 50 independent of the main board 34, the main board 34 reduces the load related to the symbol display control. It is done. Therefore, if the CPU 56 in the special symbol control board 50 is made to have a high performance, it is possible to perform complicated and varied symbol variation control and upgrade the pachinko machine P accordingly.
[0096]
Since the variation processing time is fixed, the stop timing of the symbol drum 42 in each symbol display unit U can be predicted. As a result, it becomes possible to predict whether or not the reach state before the occurrence of “big hit” will occur, whether or not the reach will further develop, and the interest of pachinko games will increase.
[0097]
Further, in the final stop symbol processing described above, even if the special symbol control board 50 receives all symbol stop commands in a timely manner during symbol variation, the final symbol pattern set on the main substrate 34 is displayed at the end of the variation pattern. It is possible to stop and display accurately on the effective line L instantly. Therefore, for example, when an operation test of the symbol variable display device 35 is performed using a simulator system, the final stop symbol is stopped and displayed on the effective line L even if an all symbol stop command is transmitted in a timely manner during symbol variation. Therefore, the test time can be greatly shortened. In addition, since the final stop symbol processing can use the normal motor processing as it is as a part of the final stop symbol processing, the processing system related to the symbol variable display device 35 can be simplified. Furthermore, since the processing pattern is selected and executed in accordance with the rotational speed of the motor 41 that is changing the design, a sudden speed change of the motor 41 is avoided and processing is performed without imposing a burden on the motor 41. it can.
[0098]
Further, for example, even if some trouble or accident occurs in the pachinko machine P, and the all symbols stop command is transmitted from the main board 34 to the special symbol control board 50 during the symbol variation by the pachinko game, the main board 34 The result of the determination in FIG. 5 and the symbol stop result in the symbol variable display device 35 always coincide with each other. As a result, if it is determined that the main board 34 is “big hit” (special game state), the symbol variable display device 35 always shows the “big hit” state, and the main board 34 is determined to be “out”. In such a case, the “variable” state always appears in the symbol variable display device 35, and inconveniences that cause distrust to the player or the hall manager are preferably avoided.
[0099]
In the above-described embodiment, the case where the alignment E including the “symbol position correction” process and the “step position correction” process is executed following the high speed D is exemplified. You may do it. That is, deceleration processing data may be selected according to the amount of deviation, and in this case as well, since the “positioning” processing is performed immediately before the stop, it is difficult to detect the stop symbol during the fluctuation.
[0100]
Furthermore, in the said Example, although the "drum type symbol variable display apparatus" which comprises the symbol drum 42 implemented in the pachinko machine P was illustrated as a symbol variable display apparatus, the symbol variable display apparatus which this invention makes object is, However, the present invention is not limited to this. For example, a “belt-type variable display device” including a design belt is also included. Further, the object of implementation is not limited to a pachinko machine, but also includes a drum-type symbol variable display device and a belt-type symbol variable display device implemented in an arrange ball machine, a slot machine, and the like.
[0101]
【The invention's effect】
  As described above, the variable symbol display device according to the present invention.Alignment of symbols inIn the method, the “step position correction” process can be performed in a fixed time to correct a step-by-step shift in one pattern. Therefore, if only a few position correction patterns are set, all the step position correction processes are suitable. Made. The step position correction is executed simultaneously with the symbol position correction for correcting the deviation amount in symbol units. Each position correction pattern is composed of a combination of multiple positioning speeds. By rotating the symbol display body by the set time for each positioning speed, the positioning of the symbols is always completed in a fixed time. Can do.
  Moreover, it is the same as the speed of change at high speed.First alignment speed and second alignment speed lower than the first alignment speedSince the step position correction is executed at a speed, the processing time required for the symbol alignment is shortened. On the other hand, since the unnatural symbol fluctuation during the step position correction processing does not occur, the player can It is difficult to realize that it is movement.
  Furthermore, since the step position correction process is executed by a special symbol control board independent of the control board that comprehensively controls the pachinko machine, the control board can reduce the load related to the symbol display control.
