Description

  The present invention relates to a gaming machine represented by a pachinko machine or a slot machine, and more particularly to a gaming machine having an annular rotating body such as a rotating drum (annular reel) configured to be rotatable.

  A slot machine, which is a kind of gaming machine, has three annular drums (annular reels) on which a plurality of symbols (a type of identification information) are arranged at predetermined intervals. The three spinning cylinders are configured to be able to rotate independently of each other, and the benefit (medal used in the game) is given to the player based on the arrangement of stop symbols after the three spinning cylinders are rotated. ) Is given. That is, when the start lever of the slot machine is pressed, the three spinning cylinders start to rotate downward and the game is started. When the predetermined condition is satisfied after the rotation starts, the rotation of the three rotating cylinders can be stopped. When the player presses the stop button in this state, the rotation of the spinning cylinder corresponding to the pressed stop button stops. When all the spinning cylinders have stopped rotating and a specific symbol row is aligned on the active line, the number of medals determined according to the symbol row are paid out to the player, and the player is profited. Is granted. Since the medal is used for starting the game, the player can perform the next game using the paid-out medal.

  In a gaming machine equipped with a spinning cylinder such as the slot machine exemplified above, each spinning cylinder is provided with an origin sensor for detecting the position of the rotation origin serving as a reference for the rotational position of the spinning cylinder. Each rotating cylinder is configured to detect the position of the rotation origin by passing (or reaching) the origin sensor through a shielding plate that rotates in synchronization with the rotation of the rotating cylinder. Therefore, in the rotation control of the rotating cylinder, when the shielding plate of the rotating rotating cylinder passes the origin sensor, the symbol number for recognizing the symbol displayed to the player and the symbol of the displayed symbol An offset number, which is a shift amount less than one symbol, is initialized.

When stopping the rotating drum, the brake processing is performed when the symbol number to be stopped is reached to stop the rotation of the rotating drum. Each cylinder is rotationally driven by 1-2 step excitation by a stepping motor, and the brake processing is performed by switching the 1-2 phase excitation to all phase excitation. As described above, the rotating cylinder is stopped by the balance between the rotating inertia moment of the rotating cylinder and the braking force. Therefore, the actual symbol stop position is determined by the rotational inertia moment of the film stuck on the surface of the rotating cylinder or the annular reel itself. In some cases, a deviation occurs between one of the cylinders and the other cylinder.
JP 2003-126337 A

  However, the adjustment of the deviation of the stop position, which can be different for each spinning cylinder, was made by changing the relative position of the origin sensor and the shielding plate with respect to the display pattern, so after completing the spinning cylinder once at the production site, There was a problem that the rotating cylinder had to be tried, and adjustment work had to be performed based on the result of the trial.

  The present invention has been made to solve the above-described problems, and simplifies or eliminates the adjustment work for mechanically changing the detection position of the rotation origin of the annular rotating body, thereby simplifying the production process. It aims to provide a gaming machine that can be used.

  In order to achieve this object, the gaming machine according to claim 1 is an annular rotator configured to be rotatable, a driving means for rotationally driving the annular rotator, and an origin for detecting a rotation origin of the annular rotator. Detecting means, and stopping means for performing stop control for stopping the rotating annular rotating body at a desired position based on the rotation origin detected by the origin detecting means, and further stopping by the stopping means A displacement amount detecting means for detecting a displacement amount of the annular rotating body caused by execution of the control, and the stop means includes a displacement amount detected by the displacement amount detection means and a rotation origin detected by the origin detection means. Based on the above, stop control is performed to stop the rotating annular rotating body at a desired position.

  According to the gaming machine of the first aspect, the rotating annular rotator driven by the driving means includes the deviation amount detected by the deviation amount detection means and the rotation origin detected by the origin detection means by the stopping means. Based on the above, stop control is performed to stop at a desired position.

  According to the gaming machine of the present invention, since the stop control is performed by the stop unit based on the shift amount detected by the shift amount detection unit and the rotation origin detected by the origin detection unit, the rotated annular rotating body Can be stopped at a desired position. Therefore, as in the past, once the annular rotator is completed, trial operation is performed at the production site, and the adjustment work for mechanically changing the detection position of the rotation origin is simplified or unnecessary, simplifying the production process. There is an effect that can be done.

An ashtray 34 or the like for storing butts is provided.

  FIG. 3 is a block diagram showing an electrical configuration of the slot machine 1. The main control board C of the slot machine 1 is disposed in the control device 40. The main control board C is equipped with an MPU 51 as a one-chip microcomputer as an arithmetic unit, and an input / output port 54 connected to the MPU 51 and connected to various I / O devices. The MPU 51 is a ROM 52 for storing various control programs executed by the MPU 51 and fixed value data, and a memory for temporarily storing various data in executing the control program stored in the ROM 52. The RAM 53 and various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are incorporated.

  The ROM 52 stores a program shown in a flowchart described later as a part of the control program. Further, an excitation time table 52a (see FIG. 4) is stored as a part of the fixed value data. Details of the excitation time table 52a will be described later when the acceleration counter 53f of the RAM 53 is described.

  In the RAM 53, a drum number memory 53a, a symbol number memory 53b, a symbol offset memory 53c, an excitation data memory 53d, an excitation time memory 53e, an acceleration counter 53f, an accelerated flag 53g, and an origin sensor SAVE flag 53h, a rotation stop position adjusting timer 53i, a post-origin distance work memory 53j, a post-origin distance storage memory 53k, a distance work memory 53m to the origin, and a distance storage memory 53n to the origin. The RAM 53 is configured so that a backup voltage is supplied from a power supply board 55 described later even after the power of the slot machine 1 is turned off, and data can be retained (backed up) after the power of the slot machine 1 is turned off. Yes.

  The rotating cylinder number memory 53a is a memory for indicating the rotating cylinder to be controlled in the motor control process (S32) and the origin sensor determination process (S50), and the value is determined by the rotating motor control process (S17). Is set. Specifically, if the value of the rotating cylinder number memory 53a is “1”, the left rotating cylinder L is designated as the control target, if “2”, the middle rotating cylinder M is specified, and if “3”, the right rotating cylinder is specified. R is designated as a control target. In the motor control process and the origin sensor determination process, a memory or the like corresponding to the spinning cylinder designated in the spinning cylinder number memory 53a is referred to, and the spinning cylinder designated in the spinning cylinder number memory 53a is controlled based on the value or the like. Is done. Note that the value “0” in the spinning cylinder number memory 53a indicates that the motor control processing has been completed for all the spinning cylinders L, M, and R on the left, middle, and right.

  The symbol number memory 53b is a memory for storing a symbol number of a symbol at a position that can be visually recognized by the player, and is provided in each of the left, middle, and right cylinders L, M, and R (53bL, 53bM, 53bR). The symbols displayed on the surface of each of the drums L, M, and R are made visible to the player by three symbols in the vertical direction from each of the exposure windows 14L, 14M, and 14R. The symbol number symbol stored in the symbol number memory 53b is in a state of being positioned just below the exposure windows 14L, 14M, 14R. Twenty-one symbols are displayed at approximately equal intervals on the surface of each cylinder L, M, R. Accordingly, a value of “0 to 20” is stored in the symbol number memory 53b corresponding to the 21 symbols. For control purposes, the value in the symbol number memory 53b may be “21” or more. In such a case, some abnormal state (rotation of the motor or circuit, or manual operation) that impedes the rotation of the rotating cylinders L, M, R. This is when an abnormality occurs in which the rotation of the rotating cylinders L, M, and R is forcibly stopped by operation. In such a case, a reacceleration setting process (S64) is performed as an abnormality process.

  The symbol offset memory 53c is a memory for storing the shift amount of the display symbol designated by the symbol number memory 53b that is less than one symbol, and is provided in each of the left, middle, and right cylinders L, M, and R. (53cL, 53cM, 53cR). The rotating cylinders L, M, and R are driven to rotate by stepping motors 64L, 64M, and 64R, respectively. Driving in this embodiment is performed by 1-2 phase excitation, and shifts by one symbol in 24 steps. As described above, since the 21 symbols are displayed on the spinning cylinders L, M, and R, the spinning cylinders L, M, and R make one rotation in 21 symbols × 24 steps = 504 steps. When the stepping motors 64L, 64M, and 64R are driven one step, the value of the symbol offset memory 53c is incremented by one. When the value of the symbol offset memory 53c after the addition reaches 24, the value of the symbol offset memory 53c is cleared to 0, and at the same time, the value of the symbol number memory 53b is incremented by 1. That is, the value of the symbol offset memory 53c is updated in the range of “0 to 23”.

  The symbol number memory 53b is initialized (cleared) by the shielding plates 67L, 67M, which are provided in the respective spinning cylinders L, M, R and rotate in synchronization with the respective spinning cylinders L, M, R. After the 67R passes the origin sensors 63L, 63M, 63R (detection of the rotation origin), the stepping motors 64L, 64M correspond to the total number of steps stored in the after-origin distance storage memory 53k and the distance storage memory 53n described later. , 64R is driven at the timing when it is driven. When the value of the symbol number memory 53b is initialized, the value of the symbol offset memory 53c is initialized again. That is, the values in the symbol number memory 53b and the symbol offset memory 53c are initialized every time the revolving cylinders L, M, and R are rotated once, so that even if the rotating cylinders L, M, and R are misaligned. This deviation can be resolved every time one rotation is made.

  The excitation data memory 53d is a memory for storing output excitation phases when the stepping motors 64L, 64M, and 64R are driven by 1-2 phase excitation, and is stored in each of the left, middle, and right cylinders L, M, and R. (53dL, 53dM, 53dR). The values stored in the excitation data memory 53d are output from the input / output port 54 to the driver circuit (not shown) of the stepping motors 64L, 64M, 64R, so that the stepping motors 64L, 64M, 64R excitation is performed.

  The excitation time memory 53e is a memory that stores the output time (excitation time) of the output excitation phase stored in the excitation data memory 53d, and is provided in each of the left, middle, and right cylinders L, M, and R. (53eL, 53eM, 53eR). Excitation of the stepping motors 64L, 64M, and 64R of this embodiment is performed in an integral multiple of 1.490 ms (milliseconds), and the timer interrupt process for controlling the driving of the stepping motors 64L, 64M, and 64R is as follows. , Executed every 1.490 ms. Therefore, the quotient obtained by dividing the excitation time by 1.490 ms is stored in the excitation time memory 53e as the excitation time. The value of the excitation time memory 53e is subtracted by 1 by the motor control process (S32). If the value is 0, the value of the excitation data memory 53d is switched to the next output excitation phase, and the excitation time is excited. It is set in the time memory 53e.

  The acceleration counter 53f is a counter used for reading the excitation time set in the excitation time memory 53e from the excitation time table 52a (see FIG. 4), and each of the left, middle and right cylinders L, M, R (53fL, 53fM, 53fR). First, the excitation time table 52a will be described with reference to FIG.

  FIG. 4 is a diagram schematically showing the configuration of the excitation time table 52a. As shown in FIG. 4, the excitation time table 52a is a data table that stores the excitation time set in the excitation time memory 53e, and is composed of 25-byte data corresponding to the values of “1 to 25” of the acceleration counter 53f. Has been. That is, the substance of the excitation time table 52a is such that 25-byte data in the column indicated as “data” in the top row is configured in the arrangement shown in FIG. The contents of the columns indicated as “excitation period”, “1-2 phase excitation”, and “acceleration direction” in the top row are explanations for understanding the excitation method of the stepping motors 64L, 64M, and 64R. Further, the value in the column indicated as “acceleration counter value” on the top line indicates the relationship between the value of the acceleration counter 53f and the data of the excitation time table 52a acquired based on the value of the acceleration counter 53f. This value is not stored in the actual excitation time table 52a.

  When starting to drive the stepping motors 64L, 64M, 64R, the value of the acceleration counter 53f is first set to “25”. The data in the excitation time table 52a corresponding to the value of the acceleration counter 53f is “129”, and this is written in the excitation time memory 53e. Each time the motor control process (S32) is executed, the value of the excitation time memory 53e is decremented by 1. When the motor control process is executed with the value of the excitation time memory 53e being 0 as a result of the subtraction, the acceleration counter 53f 1 is subtracted, and the data of the excitation time table 52a corresponding to the value of the acceleration counter 53f after the subtraction is read and set in the excitation time memory 53e. That is, after “129” is set in the excitation time memory 53e, the motor control process is executed with the value of the excitation time memory 53e being 0 after 130 interruptions described in the “Excitation period” column. In this case, the value of the acceleration counter 53f is decremented by 1 to “24”, and the value “7” of the excitation time table 52a corresponding to the “24” is set in the excitation time memory 53e. Thus, since the value of the acceleration counter 53f is updated in the subtraction direction from 25, the drive control of the stepping motors 64L, 64M, and 64R has the data in the excitation time table 52a downward as shown in the column of “acceleration direction”. Is used from above to perform acceleration control.

  Further, the acceleration of the stepping motors 64L, 64M, and 64R ends when the value of the acceleration counter 53f reaches “1”. Thereafter, constant speed driving is continued until stop control (brake processing (S59)) is started. The value of the acceleration counter 53f during constant speed driving is set to “1”. When the value of the acceleration counter 53f is set to “0”, stop control of the stepping motors 64L, 64M, and 64R is started.

  The accelerated flag 53g in FIG. 3 is a flag for indicating that the acceleration control of the stepping motors 64L, 64M, and 64R has been completed, and is provided in each of the left, middle, and right cylinders L, M, and R. (53 gL, 53 gM, 53 gR). The accelerated flag 53g is turned on when the value of the acceleration counter 53f becomes 1. When the accelerated flag 53g is turned on, and the information on the spinning cylinder is normally rotated (S82), the stop buttons 22 to 24 of the spinning cylinders L, M, and R are ready to be pressed, and stop in this state. When the buttons 22 to 24 are pressed, stop control of the corresponding spinning cylinders L, M, and R is started.

  The origin sensor SAVE flag 53h is a flag used for detecting a rotation origin serving as a reference for the rotational position of each of the spinning cylinders L, M, R, and each of the left, middle, and right spinning cylinders L, M, R. (53hL, 53hM, 53hR). In the present embodiment, the rotation origins of the rotating cylinders L, M, R are detected at the timing when the shielding plates 67L, 67M, 67R pass the origin sensors 63L, 63M, 63R. Therefore, the state of the origin sensor 63L, 63M, 63R read last time in the origin sensor determination process (S50) is stored as a flag, and the shielding plates 67L, 67M, 67R are compared with the state read this time by the origin sensor 63L. , 63M, 63R, and the rotation origin is detected.

  Here, with reference to FIG. 5, a detection method of the rotation origin of each of the spinning cylinders L, M, R will be described. FIG. 5 is a side view of the left-handed drum L, and only the rotation origin detection mechanism is shown for convenience of explanation. The arrow in the figure indicates the direction of rotation of the rotating drum L. Since the middle cylinder M and the right cylinder R are configured in the same manner as the left cylinder L, only the left cylinder L will be described, and description of the middle cylinder M and the right cylinder R will be omitted.

  The origin sensor 63L is composed of an optical sensor in which a light emitting element 63La and a light receiving element 63Lb are paired, and is fixed to a frame (not shown) to which the rotating drum L is rotatably attached. On the side surface (front side of the hand in FIG. 5) of the rotating body L on the opposite side of the frame, a cross-shaped arm 68L is provided in a side view (front view in FIG. 5). Since the center of the arm 68L is directly connected to the rotation shaft of the stepping motor 64L, when the stepping motor 64L rotates, the rotating drum L rotates together with the arm 68L. One of the four cross-shaped arms 68L is integrally fixed with a thin plate-shaped shielding plate 67L protruding toward the origin sensor 63L. The shielding plate 67L rotates with the rotating drum L by the rotation of the stepping motor 64L, and passes through the origin sensor 63L once for each rotation of the rotating drum L.

  The origin sensor 63L outputs a zero value when the light emitted from the light emitting element 63La is blocked by the shielding plate 67L and cannot be received by the light receiving element 63Lb, and conversely, the light emitted from the light emitting element 63La is reflected by the shielding plate 67L. When the light receiving element 63Lb can receive light without being blocked by the light, 1 value is output. Therefore, the timing when the output of the origin sensor 63L rises from 0 to 1 is the timing when the shielding plate 67L passes the origin sensor 63L, and this timing is the rotation origin. The origin sensor SAVE flag 53h in FIG. 3 stores the state of the origin sensor 63L detected last time in order to detect the rotation origin.

  Note that the rotation origin is not necessarily limited to the timing when the shielding plate 67L passes the origin sensor 63L. For example, the timing at which the shielding plate 67L reaches the origin sensor 63L may be set as the rotation origin. In such a case, the timing at which the output of the origin sensor 63L falls from 1 to 0 is the rotation origin. Further, as a matter of course, the output value of the origin sensor 63L may be a value opposite to that of the above embodiment. In that case, the rotation origin is detected by the reverse logic of the above embodiment.

  3 is a timer for delaying the initialization timing of the symbol number memory 53b and the symbol offset memory 53c, which is originally performed with the rotation origin as a reference. It is provided in each of the trunks L, M, R (53iL, 53iM, 53iR). By delaying the initialization timing of the symbol number memory 53b and the symbol offset memory 53c, the shift of the stop position of the rotating cylinders L, M, R is corrected. In the rotation stop position adjustment timer 53i, the total value stored in the distance storage memory 53k and the distance storage memory 53n up to the origin is set at the timing when the rotation origin is detected. As described above, each value stored in the post-origin distance storage memory 53k and the distance storage memory 53n up to the origin is stored as the number of steps of the stepping motors 64L, 64M, 64R. The symbol number memory 53b and the symbol offset memory 53c are initialized at the timing when the stepping motors 64L, 64M, and 64R are driven by the number of value steps.

  The post-origin distance work memory 53j is a work memory used for obtaining a value to be stored (stored) in the post-origin distance storage memory 53k, from the drive start position of the rotating drums L, M, R to the rotation origin. Count the distance (number of steps). It is provided in each of the left, middle and right drums L, M and R (53jL, 53jM and 53jR). The value in the post-origin distance work memory 53j is incremented by 1 when the origin sensor determination process (S50) is executed, and cleared to 0 when the rotation origin is detected. If no data is stored in the post-origin distance storage memory 53k at the start of stop control (brake processing (S59)), the value of the post-origin distance work memory 53j is written and stored in the post-origin distance storage memory 53k. Is done. Since the origin sensor determination process is executed once every time the stepping motors 64L, 64M, and 64R are driven by one step, the value of the post-origin distance work memory 53j is stored as the number of steps of the stepping motors 64L, 64M, and 64R. The The post-origin distance work memory 53j is used to store data once in the post-origin distance storage memory 53k every time the slot machine 1 is turned on. After being stored, the value of the post-origin distance work memory 53j is not practically used until the power is turned off.

  The post-origin distance storage memory 53k is a memory for storing an adjustment amount for correcting the shift of the stop position of the rotating cylinders L, M, and R together with the distance storage memory 53n to the origin to be described later. It is provided in each of the cylinders L, M, R (53 kL, 53 kM, 53 kR). In the post-origin distance storage memory 53k, the distance from the rotation origin to the position where the stop control (brake process (S59)) at the time of calculation of the adjustment amount is started is stored as the number of steps of the stepping motors 64L, 64M, 64R. Is done.

  The distance-to-origin work memory 53m is a work memory used for obtaining a value to be stored (stored) in the distance-to-origin storage memory 53n. The distance (number of steps) from the rotation origin to the stop control start position. Count. It is provided in each of the left, middle and right cylinders L, M, R (53 mL, 53 mM, 53 mR). The value in the distance work memory 53m to the origin is incremented by 1 when the origin sensor determination process (S50) is executed, and when the stop control (brake process (S59)) is started and when data is stored in the post-origin distance storage memory 53k. 0 is cleared (at this time, the value in the distance storage memory 53n is also cleared to 0 to the origin). When the rotation origin is detected, if the data is stored in the post-origin distance storage memory 53k and the data is not stored in the distance storage memory 53n up to the origin, the value of the distance work memory 53m to the origin is set to the origin. It is written and stored in the distance storage memory 53n. Since the origin sensor determination process is executed once every time the stepping motors 64L, 64M, and 64R are driven by one step, the value of the distance work memory 53m to the origin is stored as the number of steps of the stepping motors 64L, 64M, and 64R. The The distance work memory 53m to the origin is used to store data once in the distance storage memory 53n until the origin every time the slot machine 1 is turned on. After being stored, the value of the distance work memory 53m is practically not used until the origin is turned off.

  The distance storage memory 53n to the origin is a memory for storing an adjustment amount for correcting the shift of the stop position of the rotating cylinders L, M, R together with the distance storage memory 53k after the origin. It is provided in each of each cylinder L, M, R (53nL, 53nM, 53nR). In the distance storage memory 53n, the distance from the stop position where the rotating cylinders L, M, R are actually stopped to the rotation origin is set to the stepping motors 64L, 64M by performing stop control when calculating the adjustment amount. , 64R is stored as the number of steps.

  A stop position shift correction method using each value in the post-origin distance storage memory 53k and the distance storage memory 53n to the origin will be described later with reference to FIG.

  As described above, the input / output port 54 is connected to the MPU 51 including the ROM 52 and the RAM 53 and to various I / O devices. Specifically, the input / output port 54 includes a reset switch 42 for resetting the gaming state, and a setting key switch 61 provided in the setting key insertion hole 43 for switching the winning probability of the game to six stages by operating the setting key. In order to detect paid out medals, one, two, max bet buttons 26-28, a credit button 21, a start lever 29, left / middle / right turn cylinder stop buttons 22-24. Payout sensor 62, left, middle and right turn origin sensors 63L, 63M and 63R for detecting the origin positions (rotation origins) of the turn cylinders L, M and R, and left, middle and right turn Stepping motors 64L, 64M and 64R for left, middle and right turn cylinders for rotating the cylinders L, M and R, 1 to 3 bet lamps 15 to 17, and a credit number display section 1 The game number display unit 19, the payout number display unit 20, the hopper drive motor 65, the medal path switching solenoid 66, and a command transmitted from the main control board C, and a sound effect or the like is received from the speaker 12. It is connected to a sub-control board S for performing output control and controlling the display control board D to display effects on the LCD 13, and further to a power failure monitoring circuit 57 provided on the power supply board 55. . Connected to the sub control board S are an upper lamp 11, a speaker 12, and a display control board D that receives a command transmitted from the sub control board S and displays an effect on the LCD 13. Note that the sub-control board S and the display control board D are configured so that data can be transmitted and received bidirectionally.

  The power supply board 55 is provided in the above-described power supply box 44, and includes a power supply unit 56 that supplies drive power to the main control board C and each electronic device of the slot machine 1, and a power failure that monitors the occurrence of power interruption. And a monitoring circuit 57. After the power of the slot machine 1 is turned off, a backup voltage is supplied from the power supply unit 56 of the power supply board 55 to the RAM 53.

  The power failure monitoring circuit 57 is a circuit for outputting a power failure signal 58 to the NMI terminal and the input / output port 54 of the main control board C when the power is shut down due to the occurrence of a power failure or the like (including power failure due to the power switch 41 being turned off). It is. The power failure monitoring circuit 57 monitors the voltage of 24 VDC, which is the largest voltage output from the power supply board 55, and determines that a power failure (power failure) has occurred when this voltage falls below 22 volts. Thus, the power failure signal 58 is output. Based on the output of the power failure signal 58, the main control board C recognizes the occurrence of the power failure and executes the power failure process (S13). Note that the power supply board 55 outputs the output of 5 volts, which is the drive voltage of the control system, to a normal value for a time sufficient for the execution of the power failure process even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain. Therefore, the main control board C can normally execute the power failure process. Further, the power failure monitoring circuit 57 may be provided not on the power supply board 55 but on the main control board C, for example.

  Next, with reference to FIG. 6, the stop position deviation correction method in this embodiment will be described. In addition, the arrow in FIG. 6 has shown the rotation direction of the rotating drum L, M, R. UP is the upper end of the symbol that should be stopped and displayed at the upper position of the exposure windows 14L, 14M, and 14R, CP is the upper end of the symbol that should be stopped and displayed at its middle position, and DP is at the lower position. The upper ends of symbols to be stopped are shown respectively. Further, the line G is a line connecting the position where the shielding plate 67 passes the origin sensor 63 (rotation origin) and the center of the rotating cylinders L, M, R, and the line S is stopped and displayed at the lower position. This is a line connecting the upper end of the power symbol and the centers of the reels L, M, and R.

  The stop control of the rotating cylinders L, M, R is such that the rotating cylinders L, M, R reach constant speed driving and the symbol number (stop symbol number) to be stopped and the symbol number stored in the symbol number memory 53b are When they match, the brake process is performed. Since the brake processing is performed by switching the 1-2 phase excitation of the stepping motors 64L, 64M, and 64R to all phase excitation, the rotation of the rotation of the rotation L , M, and R stop, a certain amount of slippage peculiar to the rotating cylinders L, M, and R occurs.

  Here, in order to stop the symbol of symbol number “0” at the lower position DP, the brake process is executed in the state of FIG. 6A, in the state where the symbol of symbol number “0” is exactly at the lower position DP. Suppose that As a result of the brake process, when the rotating cylinders L, M, and R are stopped at the positions shown in FIG. 6B, it is understood that the slip amount Z is generated by the braking process when the rotating cylinders L, M, and R are stopped. Therefore, as shown in FIG. 6 (c), if the brake process is performed at a position where the upper end of the symbol of symbol number “0” is a front (upward) by the slippage amount Z from the lower position DP, the symbol number “0”. Can be stopped at the lower position DP.

  Therefore, it is necessary to calculate the slip amount Z. However, since the slip amount Z is generated by slipping of the stepping motors 64L, 64M, and 64R, it cannot be directly detected. Therefore, the slip amount Z is obtained as follows. First, the rotating cylinders L, M, and R are driven once, and the distance X from the position of the rotation origin (line G) to the position (line S) at which stop control (brake processing) is started (see FIG. 6B). ) Is stored. Next, the second driving of the rotating cylinders L, M, and R is performed, and the distance Y from the position (line S ′) actually stopped by the brake process to the position of the rotation origin (line G) (FIG. 6B). )) Is stored. Then, the slip amount Z is obtained as the slip amount Z = (distance for one rotation of the rotary cylinder) − (distance X + distance Y) by the two driving (trial movements) of the rotary cylinders L, M, and R.

  Even if the slip amount Z is obtained, it becomes a problem how to perform stop control at a position just before the slip amount Z. This is because, although the control can be originally delayed, the control that has already been performed cannot be returned to the state before the progress. Therefore, in this embodiment, paying attention to the fact that the rotating cylinders L, M, and R are driven to rotate, as shown in FIG. 6D, stop control (brake processing) is started from the position of the rotation origin (line G). The stop control start timing by the distance obtained by adding the distance X to the position (line S) and the distance Y from the position (line S ′) actually stopped by the brake process to the position (line G) of the rotation origin As a result, the stop control is performed at a position just before the slip amount Z. Thereby, the shift | offset | difference of a stop position is correct | amended and the spinning cylinders L, M, and R can be stopped at the correct position. Specifically, the distance X is stored in the post-origin distance storage memory 53k, and the distance Y is stored in the distance storage memory 53n up to the origin. The sum (added value) of the values in both memories 53k and 53n is set in the rotating cylinder stop position adjustment timer 53i when the rotation origin is detected, and the start timing of the stop control is shifted by the set value.

  Next, each process performed on the main control board C will be described with reference to the flowcharts shown in FIGS. FIG. 7 is a flowchart of a timer interrupt process that is periodically executed on the main control board C (every 1.490 ms in this embodiment). In this timer interrupt process, drive control of each stepping motor 64L, 64M, 64R for each cylinder, input / output process to various I / O devices, command transmission process, and the like are executed.

  In the timer interrupt process, first, a power failure process is executed (S13). In the process at the time of power failure, it is confirmed whether or not a power failure has occurred. If a power failure has occurred, backup of data or the like is performed and the subsequent processing is stopped. On the other hand, if a power failure has not occurred, the power failure process is terminated and the process proceeds to S14.

  In the processing from S14, a watchdog timer clear process (S14) for initializing the value of a watchdog timer for monitoring the occurrence of malfunction, an interrupt end declaration process (S15), and a switch state reading for reading various switch states The process (S16) and the rotating motor control process (S17) for driving the stepping motors 64L, 64M, and 64R for the left, middle, and right rotator to rotate the left, middle, and right rotators L, M, and R (See FIG. 8), sensor monitoring processing (S18) for monitoring the state of various sensors, timer subtraction processing (S19) for subtracting the value of each counter or timer, IN / OUT counter processing (S20), A command output process (S21) for transmitting a command to the control board S, a credit number display unit 18, a game number display unit 19, and a payout number display unit 20 are provided. Segment data setting process (S22) for setting the segment data to be displayed, segment data display process (S23) for displaying the segment data set by the segment data setting process on each of the display units 18 to 20, and input / output Port output processing (S24) for outputting output data from the port 54 is executed in order. After executing these processes, the timer interrupt process is terminated.

  FIG. 8 is a flowchart of the spinning motor control process (S17). In the rotating motor control process, the left, middle, and right rotating stepping motors 64L, 64M, and 64R are driven and controlled to rotate the left, middle, and right rotating cylinders L, M, and R, respectively.

  In the rotating motor control process, first, the value of the rotating cylinder number memory 53a is set to 3 (S31), and the control target is set as the stepping motor 64R for the right rotating cylinder (S32). After executing the motor control process, the value of the cylinder number memory 53a is further subtracted by 1 (S33), the value is set to 2 (S31), and the motor control process is executed with the stepping motor 64M for the intermediate cylinder. (S32). After the motor control process is executed, the value of the spinning cylinder number memory 53a is further subtracted by 1 (S33), the value is set to 1 (S31), and the motor control process is executed by setting the control target to be the stepping motor 64L for the left cylinder. (S32).

  After execution of the motor control process, 1 is further subtracted from the value of the cylinder number memory 53a (S33). As a result of the subtraction, if the value of the rotating cylinder number memory 53a is 0 (S34: Yes), the motor control process has been executed for all of the stepping motors 64L, 64M, 64R for the left, middle and right rotating cylinders. The values of the excitation data memories 53dL, 53dM, 53dR updated by the execution are output to the corresponding ports, and the output excitation phases of the left, middle, and right turn stepping motors 64L, 64M, 64R are switched, respectively. 64L, 64M, and 64R are driven.

  FIG. 9 is a flowchart of the motor control process (S32). The motor control processing is executed after the stepping motor to be controlled is designated by the value of the rotation number memory 53a by the rotation motor control processing (S17) of FIG. Specifically, when 3 is set in the rotating cylinder number memory 53a, the stepping motor 64R for the right rotating cylinder is set, and when the 2 is set, the stepping motor 64M for the middle rotating cylinder is set 1. The left turning stepping motor 64L is designated as a control target. Hereinafter, a case where 1 is set in the spinning cylinder number memory 53a and the left spinning cylinder stepping motor 64L is designated as a control target will be described as an example.

  In the motor control process, first, it is confirmed whether or not the value of the excitation time memory 53eL is 0 (S41). If it is not 0 (S41: No), the value of the excitation time memory 53eL is subtracted by 1 (S42). ), The current motor control process is terminated. On the other hand, if the value of the excitation time memory 53eL is 0 (S41: Yes), the output excitation phase of the stepping motor 64L (the value of the excitation data memory 53dL) is updated by each process after S43. The motor control process is executed once for each of the stepping motors 64L, 64M, and 64R by executing the timer interrupt process (FIG. 7) once. Since the timer interruption process is executed every 1.490 ms, excitation of the output excitation phase of the stepping motor 64L (the value of the excitation data memory 53dL) is performed for a time of 1.times.490 ms of the excitation time memory 53eL.

  In the process of S43, it is confirmed whether or not the value of the acceleration counter 53fL is 0 (S43). If it is not 0 (S43: No), the value of the acceleration counter 53fL is decremented by 1 and updated (S44). If the value of the updated acceleration counter 53fL is 0 (S45: Yes), the acceleration process is completed, so the value of the acceleration counter 53fL is set to 1 and the accelerated flag 53gL is turned on (S46). On the other hand, if the value of the updated acceleration counter 53fL is not 0 (S45: No), since the acceleration process is still in progress, the process of S46 is skipped.

  After updating the value of the acceleration counter 53fL, the excitation time data is read from the excitation time table 52a based on the updated value, written in the excitation time memory 53eL (S47), and the value of the excitation data memory 53dL is set. Update (S48) to prepare for the next excitation. Then, 1 is added to the value of the symbol offset memory 53cL (S49), and the origin sensor determination process shown in FIG. 10 is executed (S50).

  After execution of the origin sensor determination process, it is checked whether or not the value of the symbol offset memory 53cL is 23 or less (S51). If it is 24 or more (S51: No), the stepping motor 64L has shifted by one symbol. Therefore, the value of the symbol offset memory 53cL is cleared to 0 (S52), and the value of the symbol number memory 53bL is incremented by 1 (S53).

  On the other hand, if the value of the symbol offset memory 53cL is 23 or less (S51: Yes), it is confirmed whether or not the rotation of the rotating drum L is normally performed. Specifically, the value of the rotation stop position adjustment timer 53iL is 0 (S61: Yes), the value of the symbol number memory 53bL is 21 or more (S62: Yes), and the value of the symbol offset memory 53cL is 4 or more. If there is (S63: Yes), some abnormal state (motor or circuit abnormality or abnormality in which rotation of the rotating cylinder L is forcibly stopped by manual operation) that inhibits rotation of the rotating cylinder L has occurred. . Therefore, in such a case, a reacceleration setting process is executed to eliminate the abnormal state (S64), and the current motor control process is terminated. When the value of the symbol offset memory 53cL is 23 or less (S51: Yes), the value of the spinning cylinder stop position adjustment timer 53iL is other than 0 (S61: No), or the value of the symbol number memory 53bL is 21. If it is less than (S62: No), or if the value in the symbol offset memory 53cL is less than 4 (S63: No), it is determined that there is no abnormality in the rotation of the rotating drum L, and the process proceeds to S57. .

  In the processes of S57 and S58, the execution timing of the stop control is checked. If the value of the symbol offset memory 53cL is 3 or less (S57: Yes) and the value of the symbol number memory 53bL matches the stop symbol number (S58: Yes), the brake setting process is executed and the stop control of the stepping motor 64L is performed. Is performed (S59). Specifically, the acceleration counter 53fL is set to 0 to indicate the start of brake processing, the excitation data memory 53dL is set to 0FFh, the stepping motor 64L is excited in all phases, and the excitation time memory 53eL is further braked. Set the time. As a result, until the value of the excitation time memory 53eL becomes zero, all-phase excitation brake processing is performed on the stepping motor 64L, and the rotation of the rotating drum L is stopped.

  Along with the execution of the brake process (S59), a data storage process to the post-origin distance storage memory 53kL is performed (S65 to S67). First, it is confirmed whether or not data is already stored in the post-origin distance storage memory 53kL (S65), and if it is stored (S65: Yes), the execution of each process of S66 and S67 is skipped, and the brake is executed. The process is executed (S59). On the other hand, if no data is stored in the post-origin distance storage memory 53kL in the process of S65 (S65: No), the value of the post-origin distance work memory 53jL is stored in the post-origin distance storage memory 53kL (S66). After each value in the distance work memory 53mL to the origin and the distance storage memory 53nL to the origin is cleared to 0 (S67), the brake process is executed (S59).

  Since the value stored in the distance storage memory 53nL to the origin corresponds to the value in the distance storage memory 53kL after the origin, when storing data in the distance storage memory 53kL after the origin, the distance from the work memory 53mL to the origin and the distance to the origin The value of the storage memory 53nL is cleared. The post-origin distance storage memory 53kL stores the number of steps of the stepping motor 64L from the rotation origin to the stop control (brake processing) start position, and the post-origin distance storage memory 53nL stores the post-origin distance storage memory 53kL. This is because the number of steps of the stepping motor 64L from the start of driving to the detection of the rotation origin is stored by the first driving after the driving for which the number of stored steps is obtained.

  In the process of S57, if the value of the symbol offset memory 53cL is 4 or more (S57: No), or the value of the symbol number memory 53bL does not match the stop symbol number (S58: No), the brake process (S59) Execution is skipped. The stop symbol number is normally set to 0FFh. When the stop button 22 is pressed, the stop symbol at the lower position DP is determined, and the determined symbol number of “0-20” is the stop symbol number. Is written to. Therefore, in the state before the stop button 22 is pressed, the value of the symbol number memory 53bL is always inconsistent with the symbol number of the stop symbol, so that stop control (brake processing) is not performed.

  After the execution of the brake process (S59), when the value of the acceleration counter 53fL is 0 and the value of the excitation time memory 53eL is 0 (S41: Yes, S43: Yes), the brake process is completed. Therefore, in such a case, the value of the excitation data memory 53dL is set to 0, the stepping motor 64L is turned off for all phases, and a series of the process of driving the rotating drum L is completed.

  FIG. 10 is a flowchart of the origin sensor determination process (S50) executed in the motor control process (S32). Similarly to the motor control process, the origin sensor determination process is also executed after the stepping motor to be controlled is specified by the value of the cylinder number memory 53a by the cylinder motor control process (S17) of FIG. Specifically, when 3 is set in the rotating cylinder number memory 53a, the stepping motor 64R for the right rotating cylinder is set, and when the 2 is set, the stepping motor 64M for the middle rotating cylinder is set 1. The left turning stepping motor 64L is designated as a control target. Hereinafter, a case where 1 is set in the spinning cylinder number memory 53a and the left spinning cylinder stepping motor 64L is designated as a control target will be described as an example.

  In the origin sensor determination process, first, one is added to each value of the distance work memory 53jL after the origin and the distance work memory 53mL to the origin (S70), and then the output information of the origin sensor 63L is read (S71). As described above, the origin sensor 63L of the present embodiment outputs a zero value when the light emitted from the light emitting element 63La is blocked by the shielding plate 67L and cannot be received by the light receiving element 63Lb, and conversely, the light emitted from the light emitting element 63La. When the received light is not blocked by the shielding plate 67L and can be received by the light receiving element 63Lb, 1 value is output. If the read output value of the origin sensor 63L is 0 (S72: No), the origin sensor SAVE flag 53hL is turned off (S73), the current output information of the origin sensor 63L is stored, and the process proceeds to S77. . On the other hand, if the read output value of the origin sensor 63L is 1 (S72: Yes), the state of the origin sensor SAVE flag 53hL, that is, the previous output information of the origin sensor 63L is checked (S74). (S74: Yes), since there is no change in the output information of the origin sensor 63L, the process proceeds to S77.

  On the other hand, if the read output value of the origin sensor 63L is 1 (S72: Yes) and the origin sensor SAVE flag 53hL is off (S74: No), the output of the origin sensor 63L rises from 0 to 1. It will be. That is, the timing when the shielding plate 67L passes through the origin sensor 63L and the arrival of the rotation origin. In such a case, the process proceeds to S75, and the origin sensor SAVE flag 53hL is turned on to store the current output information of the origin sensor 63L (S75). The value of the post-origin distance work memory 53jL for counting the distance (number of steps) is cleared to 0 (S91).

  It is confirmed whether or not data is stored in the post-origin distance storage memory 53kL (S92). If not stored (S92: No), data storage to the distance storage memory 53nL to the origin and a rotation stop position adjustment timer are performed. Since an official value cannot be set to 53iL, in such a case, a default value is set to the spinning cylinder stop position adjustment timer 53iL (S93), and the current origin sensor determination process is terminated. In this case, since the value corresponding to the slip amount Z cannot be set in the rotating cylinder stop position adjustment timer 53iL, the shift correction of the stop position is not performed accurately.

  On the other hand, if the data is stored in the post-origin distance storage memory 53kL (S92: Yes), it is further confirmed whether the data is already stored in the distance storage memory 53nL up to the origin (S94), and the data is stored. If not (S94: No), the value of the distance work memory 53mL to the origin for counting the distance (number of steps) from the drive start position after the stop to the origin of rotation is stored in the distance storage memory 53nL to the origin (S95). . After the data is stored in the distance storage memory 53nL up to the origin, or when the data is already stored in the distance storage memory 53nL up to the origin in the process of S94 (S94: Yes), the process proceeds to S96. In the process of S96, the value of the post-origin distance storage memory 53kL and the value of the distance storage memory 53nL to the origin are added, and this is set in the rotating cylinder stop position adjustment timer 53iL (S96). Exit.

  In the process of S77, it is confirmed whether or not the value of the rotation stop position adjustment timer 53iL is 0 (S77). If it is 0 (S77: Yes), the current origin sensor determination process is terminated. On the other hand, if the value of the rotation stop position adjustment timer 53iL is not 0 (S77: No), the value is subtracted by 1 (S78), and if the subtraction result is not 0 (S79: No), the current origin sensor determination End the process. If the subtraction result is 0 (S79: Yes), each value of the symbol number memory 53bL and the symbol offset memory 53cL is initialized (cleared to 0) (S80). Initialization of each value of the symbol number memory 53bL and the symbol offset memory 53cL is originally performed at the arrival timing of the rotation origin. However, in the present embodiment, such initialization is delayed by the value obtained by adding the value of the post-origin distance storage memory 53kL and the value of the distance storage memory 53nL to the origin, so that the position of the stop position of the cylinder L is reduced. The deviation is corrected by software control (see FIG. 6D). That is, with this configuration, the start timing of the stop control (brake process) can be delayed by the number of steps corresponding to the slip amount Z, so that the rotating drum L is stopped at a desired position regardless of the slip amount Z. It can be done.

  After the processing of S80, the state of the accelerated flag 53gL is checked (S81), and if it is off (S81: No), since the rotating drum L is still in the acceleration driving state, the current origin sensor determination is performed as it is. The process ends. On the other hand, if the accelerated flag 53gL is on (S81: Yes), the acceleration driving of the rotating drum L has already been completed and the constant speed driving has been completed. The origin sensor determination process ends. By setting the drive information of the rotating drum L to normal rotation, the stop button 22 can be pressed, that is, the rotating drum L can be stopped.

  As described above, according to the slot machine 1 of the present embodiment, in order to correct the displacement of the stop positions of the rotating cylinders L, M, R, the distance between the post-origin distance storage memory 53k and the distance storage memory 53m up to the origin is determined. A value is obtained, and an added value of these values is set in the rotating cylinder stop position adjustment timer 53i when the rotation origin is detected. Then, at the timing when the value of the spinning cylinder stop position adjustment timer 53i becomes 0, each value of the symbol number memory 53b and the symbol offset memory 53c is initialized. Originally, initialization of each value of the symbol number memory 53b and the symbol offset memory 53c is performed at the arrival timing of the rotation origin. However, as in the present embodiment, such initialization is performed with the value of the post-origin distance storage memory 53k. By performing a delay by an added value with respect to the value of the distance storage memory 53m to the origin, it is possible to automatically correct the deviation of the stop positions of the cylinders L, M, and R by software control. Therefore, after completing the rotating cylinders L, M, and R as in the past, the trial operation is performed at the production site, and the adjustment work for mechanically changing the detection position of the rotation origin is simplified or made unnecessary. The process can be simplified.

  In addition, since it is not necessary to configure the slot machine 1 so that the position of the rotation origin can be mechanically adjusted, the simplification of the structure of the rotating cylinders L, M, and R and the simplification of the design accompanying that, The apparatus cost can be reduced. However, the slot machine 1 having the configuration of the present embodiment may be mounted with a mechanical adjustment mechanism for the rotation origin of the rotating cylinders L, M, R.

  Furthermore, the shift correction can be performed with high accuracy and detail by performing the shift position correction by software control. For example, since the number of steps of the stepping motors 64L, 64M, 64R is stored as the value set in the spinning cylinder stop position adjustment timer 53i of the present embodiment, the maximum value is 1 of the spinning cylinders L, M, R. It is 503 corresponding to less than the circumference (the rotating drum of this embodiment makes one round in 504 steps). In the conventional mechanical adjustment, the relative position between the origin sensor and the shielding plate is finally changed to three at most due to structural limitations. In this way, the mechanical adjustment that has been conventionally performed is three steps, but in the case of the present embodiment, it can be adjusted to a maximum of 503 steps, so that the deviation correction can be performed with high accuracy and detail. It is. In addition, since the correction of the displacement of the conventional stop position is performed by adjusting the relative position between the origin sensor 63 and the shielding plate 67, the film attachment position (for example, the film attachment position) on which a plurality of symbols are displayed. The landing position) was naturally limited to a position within a certain range of the drums L, M, and R. However, according to the slot machine 1 of the present embodiment, since the shift of the stop position can be corrected with respect to the entire range of one rotation of the rotating cylinders L, M, and R, the sticking position of the film can be determined. There is no limit. Therefore, it is possible to simplify the operation of attaching the film to the rotating drums L, M, and R.

  The value of the post-origin distance storage memory 53k can be obtained by driving and stopping the rotating cylinders L, M, and R once. The value of the distance storage memory 53m to the origin is the value of the post-origin distance storage memory 53k. After obtaining, it can be obtained by driving the rotating cylinders L, M, R again. If the value of the distance storage memory 53m is obtained up to the origin following the value of the post-origin distance storage memory 53k, it is possible to accurately correct the deviation of the stop position. As described above, according to the slot machine 1 of the present embodiment, it is possible to automatically perform the shift correction of the stop position from the second and subsequent driving of the rotating cylinders L, M, and R without any operation.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  In the above-described embodiments, the rotating bodies (annular reels) L, M, and R that are driven and controlled by the main control board C have been described as examples of the annular rotating body. However, in the case where an auxiliary reel (auxiliary cylinder) is provided separately from the rotating cylinders L, M, and R, and the auxiliary reel is driven and controlled by the sub-control board S, the present invention is applied to the auxiliary reel as an annular rotating body. You may make it do. Further, in the case of a pachinko machine equipped with a rotating body such as a rotating drum, the present invention may be applied to the rotating body.

  The value set in the rotating cylinder stop position adjusting timer 53i for correcting the shift of the stopping positions of the rotating cylinders L, M, R is the number of steps of the stepping motors 64L, 64M, 64R. Thus, actual driving distance and driving time data may be set in the rotating cylinder stop position adjustment timer 53i.

  The post-origin distance storage memory 53k corresponding to the post-origin value storage means and the distance storage memory 53n to the origin corresponding to the value storage means up to the origin are not necessarily constituted by two memories. It may be configured. That is, an addition value between the value in the post-origin distance storage memory 53k and the value in the distance storage memory 53n up to the origin is stored in one memory, and this addition value is directly set in the rotation stop position adjustment timer 53i. Anyway.

  Further, a post-origin distance storage memory 53k corresponding to the post-origin value storage means and a distance storage memory 53n corresponding to the value storage means up to the origin may be provided in a nonvolatile EEPROM or flash ROM. Further, these may be provided in the static RAM and the data may be backed up. According to such a configuration, each value of the distance storage memory 53k and the distance storage memory 53n until the origin is temporarily stored, so that the deviation correction of the stop position can be accurately performed even at the first driving after turning on the gaming machine. It can be carried out.

  On the other hand, when the post-origin distance storage memory 53k corresponding to the post-origin value storage means and the distance storage memory 53n up to the origin corresponding to the value storage means are configured so as not to be backed up, only the first drive after the power is turned on. Since the shift correction of the stop position cannot be automatically performed, the rotating cylinders L, M, R may be tried once or twice or more after the power is turned on. Even in one trial movement, the deviation correction of the stop position can be automatically performed from the time when the next drive is stopped. However, in an environment where the spinning cylinders L, M, and R are forcibly rotated manually after one trial motion, the trial motion is performed twice, and the two trial motions cause the It is preferable to determine both values of the distance storage memory 53k and the distance storage memory 53n to the origin. After confirming both values in the distance storage memory 53k after the origin and the distance storage memory 53n up to the origin, even if the rotating cylinders L, M, and R are forcibly rotated manually, the displacement correction of the stop position is accurate. It is because it can be performed.

  You may implement this invention in the pachinko machine etc. of a different type from the said Example. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Moreover, after the jackpot symbol is displayed, it may be implemented as a pachinko machine that enters a special game state under the condition that a ball is awarded in a predetermined area. Further, in addition to the pachinko machine, the game machine may be implemented as various game machines such as an alepatchi, a sparrow ball, a slot machine, a game machine in which a so-called pachinko machine and a slot machine are integrated.

  In the slot machine, for example, a symbol is changed by operating a control lever in a state where a symbol effective line is determined by inserting coins, and a symbol is stopped and confirmed by operating a stop button. Is. Therefore, the basic concept of the slot machine is that it is provided with variable display means for confirming and displaying the identification information after variably displaying the identification information string composed of a plurality of identification information, and resulting from the operation of the starting operation means (for example, the operation lever) Then, the change of the identification information is started, and the change of the identification information is stopped due to the operation of the operation means for stop (for example, the stop button) or after the lapse of a predetermined time, and the fixed identification information at the time of the stop Is a slot machine provided with special game state generating means for generating a special game state advantageous to the player on the condition that the specific identification information is a necessary condition. In this case, coins, medals, etc. are representative examples of game media As mentioned.

  In addition, as a specific example of a gaming machine in which a pachinko machine and a slot machine are integrated, a variable display means for displaying a fixed symbol after displaying a variable symbol sequence consisting of a plurality of symbols is provided, and a handle for launching a ball is provided. What is not provided. In this case, after insertion of a predetermined amount of spheres based on a predetermined operation (button operation), for example, the variation of the symbol is started due to the operation of the operation lever, for example, due to the operation of the stop button, or With the passage of time, the fluctuation of the symbol is stopped, and a jackpot state advantageous to the player is generated on the condition that the confirmed symbol at the time of stoppage is a so-called jackpot symbol. A lot of balls are paid out.

  The gaming machine of the present invention and its modifications are shown below. An annular rotator configured to be rotatable, drive means for rotationally driving the annular rotator, origin detection means for detecting the rotation origin of the annular rotator, and a rotation origin detected by the origin detection means In a gaming machine comprising stop means for performing stop control for stopping the rotating annular rotator at a desired position, a deviation amount of the annular rotator generated by execution of the stop control by the stop means is detected. The stop means includes a deviation amount detection means, and the stopping means places the rotating annular rotating body at a desired position based on the deviation amount detected by the deviation amount detection means and the rotation origin detected by the origin detection means. A gaming machine 1 that performs stop control for stopping.

  An annular rotator configured to be rotatable, drive means for rotationally driving the annular rotator, origin detection means for detecting the rotation origin of the annular rotator, and a rotation origin detected by the origin detection means And a stop means for performing stop control for stopping the rotating annular rotator at a desired position, and a stop control start position by the stop means from the rotation origin detected by the origin detection means. Alternatively, the post-origin value storage means for storing the value up to the stop target position, and the rotation origin is detected by the origin detection means from the position stopped by the stop control for obtaining the value stored in the post-origin value storage means. Value storage means up to the origin for storing the value of the value, and the stop means includes values stored in the post-origin value storage means and the value storage means up to the origin and the origin detection means. Game machine 2 which issued on the basis of the rotation origin is characterized in that it is intended to perform a stop control for stopping the annular rotary body during rotation to a desired position. According to the gaming machine 2, stop control is performed by the stop means based on the value stored in the post-origin value storage means and the value storage means up to the origin and the rotation origin detected by the origin detection means. The made annular rotating body can be stopped at a desired position. Therefore, as in the prior art, once the annular rotator is completed, the production process can be simplified by eliminating or eliminating the adjustment work of mechanically changing the detection position of the rotation origin after trial operation at the production site. . In addition, since it is not necessary to have a configuration in which the position of the rotation origin can be mechanically adjusted, the apparatus cost can be reduced correspondingly by simplifying the structure of the annular rotating body and simplification of the design. be able to. However, a mechanical adjustment mechanism for the rotation origin of the annular rotator may be mounted on the configuration of the gaming machine 2 together.

  In the gaming machine 2, examples of values stored in the value storage means after the origin and the value storage means up to the origin include the driving distance and driving time from or to the rotation origin, or the number of driving steps. Can do. In particular, when the driving time is used as the value stored in the value storage unit and the value after the origin, it is preferable that the annular rotator is driven at a constant speed at all times. Further, when the number of drive steps is used as the value stored in the value storage means until the origin, the drive means may be composed of a drive device capable of step driving (for example, a stepping motor). It is a condition. Further, in the gaming machine 2, the stop control start position can be exemplified as a brake process start position for stopping the rotational drive of the drive means, and the stop target position is intended to be stopped by the brake process. The target position to be performed can be exemplified. Further, the post-origin value storage means may be exemplified by a post-origin distance storage memory, and the value storage means may be exemplified by a distance storage memory up to the origin.

  In the gaming machine 2, rotational position storage means for storing a relative rotational position of the annular rotator with respect to the rotation origin, and rotational position update means for updating the contents of the rotational position storage means as the annular rotator rotates. After the rotation origin is detected by the origin detection means, the contents of the rotation position storage means are initialized after the rotation of the annular rotating body for the value stored in the value storage means and the post-origin value storage means. The game machine 3 is characterized in that it comprises a rotation position initialization means for converting the stop position into a stop position based on a rotation position stored in the rotation position storage means.

  Conventional correction of the deviation of the stop position was done by adjusting the relative position of the origin sensor and the shielding plate, so the film sticking position with multiple symbols displayed on the annular rotating body is naturally within a certain range. Limited to. However, the initialization position of the contents of the rotation position storage means by the rotation position initialization means is set for all ranges of one rotation of the annular rotator based on the value stored in the value storage means and the post-origin value storage means. Since it can set, the sticking position of this film is not restrict | limited. Therefore, the film sticking work to the annular rotating body can be simplified. As the rotational position storage means, for example, the symbol number memory for storing the symbol number of the symbol displayed on the player among the surface symbols of the annular rotating body, or the transition of less than one symbol of the displayed symbol A set of the symbol offset memory and the symbol number memory which are quantities can be exemplified. Further, the initialization by the rotational position initialization means is not necessarily limited to clearing the contents of the rotational position storage means to zero, but may be initialization set to a predetermined value.

  In the gaming machine 2 or 3, the value storage means until the origin is rotated by the origin detection means by the first driving of the annular rotating body after the stop control for which the value stored in the post-origin value storage means is obtained. A gaming machine 4 in which a value until the origin is detected is stored. According to the gaming machine 4, the value stored in the value storage means up to the origin can be stored in association with the stop control obtained from the value stored in the post-origin value storage means, so that the stop position can be corrected by the stop means. It can be done more accurately.

  In any of the gaming machines 2 to 4, when a value is stored in the post-origin value storing means, a value erasing means that clears the value stored in the value storing means up to the origin is provided. Machine 5. The correction of the deviation of the stop position by the stop means becomes effective by storing the value of the value storage means up to the origin in association with the value of the post-origin value storage means. According to the gaming machine 5, when the value is stored in the post-origin value storage means, the value stored in the value storage means is cleared up to the origin by the value erasing means. Therefore, when the value is stored in the post-origin value storage means, the annular rotator is driven in a state where the value unrelated to the value stored in the post-origin value storage means remains (stored) in the value storage means up to the origin. There is no control. Accordingly, it is possible to accurately correct the deviation of the stop position.

  In any of the gaming machines 2 to 5, trial means for trial-running the annular rotating body at least once in order to store respective values in the post-origin value storage means and the value storage means up to the origin. A gaming machine 6 characterized by comprising. According to the gaming machine 6, when the annular rotator is tried at least once by the trial movement means, the value of the post-origin value storage means is obtained and stored by the trial movement. When the annular rotating body is further driven after execution of the trial movement means, the value storage means value is obtained and stored up to the origin corresponding to the value of the post-origin value storage means. Based on these values, It is possible to correct the deviation of the stop position from the time when the drive is stopped. Therefore, the deviation of the stop position can be accurately performed in the subsequent driving of the annular rotator by executing the trial moving means.

  In any one of the gaming machines 2 to 6, the driving means has a stepping motor, and the annular rotating body is rotationally driven by the rotation of the stepping motor. The post-origin value storage means and the value storage to the origin A value stored in the means is stored as the number of steps of the stepping motor. According to the gaming machine 7, the number of steps of the stepping motor that rotationally drives the annular rotator can be set to an adjustment value for correcting the deviation of the stop position of the annular rotator. Can be done. In the conventional mechanical adjustment, the relative position between the origin sensor and the shielding plate is finally changed to three at most due to structural limitations. On the other hand, by using the step number of the stepping motor as an adjustment value, for example, an annular rotating body that rotates once in 504 steps can have adjustment values in a maximum of 503 stages. This can be performed in detail and with high accuracy. Note that the number of steps of the stepping motor does not necessarily have to be used as the adjustment value as it is. For example, a number obtained by multiplying the number of steps by n may be stored as the adjustment value.

  In the gaming machine 7, the driving means is a constant speed drive after accelerating the stepping motor, and the stop control of the annular rotating body by the stopping means is performed only during the constant speed driving of the stepping motor. A gaming machine 8 characterized by According to the gaming machine 8, since the stop control of the annular rotator is performed only when the stepping motor is driven at a constant speed, the stop control can always be performed under substantially the same condition. Can be made substantially the same amount. Accordingly, the rotating annular rotating body can be reliably stopped at a desired position by the stop control of the stop means.

  In any one of the gaming machines 2 to 8, the post-origin value storage means and the value storage means up to the origin are configured by a nonvolatile memory capable of storing values even after the gaming machine is turned off. Gaming machine 9. According to the gaming machine 9, after each value is once stored in the post-origin value storage means and the value storage means up to the origin, even if the gaming machine is turned off, those values are retained, so that the stop Position shift correction can be performed accurately.
