Description

  The present invention relates to a gaming machine represented by a swivel type gaming machine.

  As is well known, a unit game by a revolving game machine is started when a player bets a game medium and operates a start lever, and any of the profits (re-games and various small roles) is performed by internal processing. And various bonus combinations such as a big bonus combination and a regular bonus combination are determined, and a plurality of spinning cylinders having a symbol row are rotated. Thereafter, by operating the stop button, the rotation of the plurality of spinning cylinders stops, and the unit game ends. At the end of the unit game, if any of the symbol patterns that make up the profit combination is displayed on a predetermined active line corresponding to the number of bets, a new game medium is bet in the case of a re-game combination. The player enters a re-playing state where the next unit game can be performed without any change, and in the case of a small role, a predetermined number of game media according to the type of the small role is paid out. Transition to a special gaming state that is extremely advantageous to the player who has played.

  Each spinning cylinder of the spinning cylinder game machine starts rotating according to the operation of the start lever and stops according to the operation of the stop button. Specifically, when the start lever is operated, the state shifts to an acceleration state where acceleration of the rotating cylinder starts, and when the predetermined rotational speed is reached, the rotating cylinder shifts to a steady rotation state that maintains the rotation at that speed. . On the other hand, when the stop button is operated, the process shifts to a decelerating state in which the rotating cylinder rotating at a constant speed is decelerated, and finally the rotating cylinder stops. A stepping motor is known as a drive motor used for driving control of such a rotating drum (see, for example, Patent Document 1). Since the stepping motor has a large rotational torque, it is possible to accelerate the rotating drum to a predetermined rotational speed in a short time and stop the rotation of the rotating drum in a short time compared to other motors. In addition, the stepping motor rotates the rotating cylinder by a predetermined constant angle in response to reception of the control pulse signal, so that a desired level of accuracy can be obtained by cyclic excitation of a plurality of types of excitation phases by transmission of the control pulse signal. The rotating drum can be stopped at a rotation angle. Therefore, it is possible to stop an arbitrary symbol attached to the rotating drum at a desired position with high accuracy. Usually, a plurality of symbols are arranged at equal intervals on the rotating drum, and the current symbol is changed to the next symbol by transmitting the control pulse signal a plurality of times.

  In the deceleration state of the stepping motor, normally, excitation is performed by all-phase excitation phases that collectively select all of a plurality of types of rotation excitation phases in the steady rotation state. In all-phase excitation phases, substantially all of the magnetic stable angles corresponding to the excitation of each of the one-phase excitation phases among a plurality of types of rotational excitation phases are stable angles. Therefore, even if it is desired to stop at a desired stop angle among the stable angles, the interval between the stable angles is set as the “stable step angle”, and if the half of the stable step angle is exceeded from the desired stop angle, the desired In some cases, the vehicle stops at a stable angle immediately after the stop angle. Moreover, the case where it stops at the stable angle just before a desired stop angle is also considered. Such deviation of the stop angle is caused by a manufacturing error of the stepping motor, excessive heating of the stepping motor, a change in the driving current (driving voltage) of the stepping motor, a secular change in torque necessary for the rotation of the stepping motor, and the like. . This is because in such a case, the torque when excitation by all-phase excitation phases is performed is different from that at normal time.

Therefore, in the present invention, the stop accuracy when stopping the rotating drum is improved.

In order to solve the above problems, a gaming machine according to the present invention is:

It is characterized by that.

  With the gaming machine of the present invention, stopping accuracy is improved when stopping the rotating drum.

The gaming machine according to the present invention has the following configuration.
Means 1.
A symbol display means for displaying a symbol including a rotatable rotator provided with a symbol row (for example, a symbol row of a symbol sticker), and a symbol display variation for changing the symbol display by rotating the gyrus of the symbol display means. And a fluctuation control means for controlling rotation of the rotating drum by the symbol display changing means (for example, rotating rotation processing and stepping motor control processing). And
It further includes stop input means (for example, a stop button) for inputting an instruction to stop the spinning cylinder according to an operation by the player,
The symbol display changing means includes a stepping motor for rotating the rotating drum,
The fluctuation control means is
Different types of rotational excitation phases (for example, combinations of A phase, B phase, inverted A phase and inverted B phase, A phase, (A + B) phase, B phase, (B + inverted A) phase, inverted A phase, ( (Reversed A + inverted B) phase, inverted B phase and (inverted B + A) phase combination) in a predetermined rotation excitation order (for example,... → A phase → B phase → reversed A phase → reversed B phase → A phase → .. or order ... → A phase → (A + B) phase → B phase → (B + inverted A) phase → inverted A phase → (inverted A + inverted B) phase → inverted B phase → (inverted B + A) phase → A Motor rotation means (for example, acceleration counter setting process) that cyclically selects the phase step and then drives the stepping motor;
Displacement angle update means (for example, symbol number update processing, symbol offset update processing, and rotation) for updating displacement angle information (for example, symbol number and symbol offset) for identifying the displacement angle of the rotor with the rotation of the rotor. Position adjustment processing)
In response to an input of the stop instruction from the stop input means, scheduled stop angle control means (for example, a stop symbol number and a stop symbol offset) corresponding to the expected stop angle of the rotating cylinder (for example, stop symbol number and stop symbol offset) , Rotation control processing),
In response to an input of the stop instruction from the stop input means, referring to the angular displacement information and the scheduled stop angle information, an all-phase excitation phase that excites the plurality of types of rotational excitation phases at once (for example, All phases), and after selecting all of the phase excitation phases, select a specific excitation phase (for example, phase A) that makes the planned stop angle magnetically the most stable displacement angle, and Motor stop means (stop start determination process, deceleration counter setting process) for selecting the all-phase excitation phase after the selection and selecting the stop excitation order to stop the driving of the stepping motor;
It is characterized by including.

In this specification, the “scheduled stop angle” implies the case where only one angle is selected at a time by the planned stop angle control means, or the case where a plurality of angles are selected at a time.
In this specification, the “specific excitation phase” is excited by combining the same excitation phase as any one of a plurality of types of rotation excitation phases and a combination of two or more types of rotation excitation phases among the plurality of types of rotation excitation phases. It implies the excitation phase, all of the multiple types of rotational excitation phases, and a different dedicated excitation phase. The specific excitation phase implies a fixed excitation phase in the operation of the gaming machine and a variable excitation phase selected from a plurality of types of excitation phases.

  With the above configuration, the pulling angle range of the all-phase excitation phase is centered on the planned stop angle without sufficient deceleration due to the all-phase excitation phase preceding the specific excitation phase in the stop driving state of the stepping motor. As long as it is within the pulling angle range of the specific excitation phase, the pulling angle range centered on the planned stop angle by the specific excitation phase is larger than the pulling angle range of all the phase excitation phases. By the specific excitation phase, it can be pulled back within the scheduled stop angle range by all phases. Conversely, when the stepping motor is stopped, excessive deceleration is performed by the all-phase excitation phase preceding the specific excitation phase, and the displacement angle does not reach the pull-in angle range of the all-phase excitation phase from the planned stop angle. However, since the pull-in angle range by the specific excitation phase is larger than the pull-in angle range by the all-phase excitation phase, the pull-in angle range by the specific excitation phase is within the pull-in angle range of the all-phase excitation phase as long as it is within the pull-in angle range by the specific excitation phase. You can pull in. As a result, the accuracy of stopping the rotating drum at a predetermined scheduled stop angle is improved. In a normal state, the structure may be such that the spinning cylinder completely stops during the excitation of the specific excitation phase, or the spinning cylinder may not completely stop during the excitation of the specific excitation phase. If the spinning cylinder does not stop completely during the excitation of the specific excitation phase, the spinning cylinder will stop completely during the excitation of all the phase excitation phases following the specific excitation phase.

  Furthermore, with the above configuration, the speed of the rotating cylinder when reaching the planned stop angle is lower than that when decelerating by a specific excitation phase without going through all-phase excitation phases. Since the maximum vibration width of the rotating drum in the vicinity of the angle is reduced and the vibrating time of the rotating drum is shortened, the stop to the planned stop angle becomes smooth.

Each pressing portion 1375a, 1375b is formed in a tongue-like shape, and protrudes in the radial direction of the shaft member 1362, respectively. The opening / closing member 1363 includes a plurality of closing portions 376 for closing each of the plurality of ball passages 1402 and pressed portions 1378a and 1378b that receive stress for moving the opening / closing member.

  The state shown in FIG. 4 is a state where the pressing portion 1375a presses the pressed portion 1378a and the opening / closing member 1363 is moved to the right side. In this state, a game to each of the plurality of ball paths 1402 is performed. Sphere inflow is allowed. When the shaft member 1362 is rotated clockwise as viewed from above in FIG. 4 by operating the operation handle from the state shown in FIG. 4, the pressing portion 1375b is directed substantially in the horizontal direction and the pressed portion of the opening / closing member 1363 Press 1378b. As a result, the opening / closing member 1363 moves to the left, and the size of the entrance of the closed portion 1376 of the spherical passage 1402 is reduced. In this state, the inflow of game balls into each of the plurality of ball paths 1402 is prohibited. In this state, even if the selector 1400 is removed in a state where the game balls are stored in the upper plate 1302 and the game ball guide path 1322, those game balls will not be dropped. Conversely, when the shaft member 1362 is rotated counterclockwise by operating the operation handle from this state, the inflow of game balls into each of the plurality of ball passages 1402 is permitted.

  As shown in FIG. 5, the upper dish ball removing portion 1380 includes a base portion 1381 attached to the lower side of the upper plate unit main body 1320 via the CR operation display portion 1350, and a support shaft erected on the base portion 1381. 1382, a rotating piece 1384 and a pressing piece 1385 that rotate about 1383, and an upper dish ball removing lever 1386 that slides along the front surface of the base portion 1381. A connecting portion 1384 b that is pivotally attached to an upper dish ball removing lever 1386 is provided on the base portion 1384 a of the rotating piece 1384. In addition, the base portion 1384 a of the rotating piece 1384 is connected to the base portion 1381 via a coil spring 1387. A bifurcated grip 1384 c is provided at the tip of the rotating piece 1384. The grip portion 1384c is a portion that slidably grips the convex portion 1385b provided on the base portion 1385a of the pressing piece 1385. A pressing portion 1385 c that presses the return shutter 1420 of the selector 1400 is provided at the tip of the pressing piece 1385. The hollow protrusion 1408 of the selector 1400 stores a coil spring that presses the return shutter 1420 toward the pressing piece 1385 side.

  The state shown in FIG. 5 is a state where the upper dish ball removing lever 1386 is not operated. That is, the rotating piece 1384 is pulled counterclockwise by the coil spring 1387, and the pressing piece 1385 is pulled clockwise by the rotating piece 1384, so that the pressing portion 1385c is separated from one end of the return shutter 1420. State. In this state, the return shutter 1420 is at the reference position by the urging force of the coil spring 1430 disposed inside the hollow protrusion 1408. From this state, if the upper dish ball removal lever 1386 is picked and moved downward in the figure (actually, from the right side to the left side when viewed from the front of the ball-type revolving game machine 1010), the upper dish ball removal lever 1386 is rotated. The moving piece 1384 rotates clockwise, and the pressing piece 1385 is rotated counterclockwise by the rotating piece 1384, and the pressing portion 1385 c presses the return shutter 1420. As a result, the return shutter 1420 moves. In this state, when the hand is released from the upper tray ball removal lever 1386, the return shutter 1420 is pressed forward by the urging force of the coil spring disposed in the hollow protrusion 1408, and the state shown in FIG. 5 is restored.

  As described above with reference to FIG. 3, the selector 1400 includes a plurality of game ball insertion portions 1410 a, 1410 b, 1410 c, a return shutter 1420, a return switch board 1440, a board cover 1450, and a return shutter 1420. A coil spring (not shown) for returning to the reference position and a selector relay device 1460 are provided.

  As shown in FIG. 3, the game ball throwing portion 1410 a of the selector 1400 includes a resin casing including a casing 1411 and a cover 1412. The outer surface of the casing 1411 is an attachment surface for the cover 1412 of the adjacent game ball insertion portion 1410b, and the outer surface of the cover 1412 of the game ball insertion portion 1410a is an attachment surface for the substrate cover 1450. When the casing 1411 and the cover 1412 are assembled, a bowl-shaped portion 1417 constituting the ball passage 1402 is formed. As shown in FIG. 4, the game ball throwing portion 1410 a passes through a throwing flicker 1413 a (a kind of medium inflow restriction means) and a throwing solenoid 1414 a (a kind of inflow restriction changing means), as shown in FIG. 4. A sensor 1415a and a count sensor 1416a are provided. In addition, a guide passage 1404 extending obliquely downward and a discharge passage 1406 extending substantially vertically downward are formed in the game ball throwing portion 1410a on the downstream side of the ball passage 1402.

  The input flicker 1413a regulates the inflow of game balls from the ball passage 1402 to the discharge passage 1406. The insertion flicker 1413a has a proximal end portion 1413a1 and a distal end portion 1413a2 that are rotatably connected by a support shaft 1413a3. The proximal end side portion 1413a1 and the distal end side portion 1413a2 of the input flicker 1413a are rotatably supported by the support shafts 1411a1 and 1411a2 of the casing 1411a, respectively. A gripping portion 1413a4 for gripping the tongue piece 1414a1 of the closing solenoid 1414a is provided at the proximal end portion of the closing flicker 1413a. In addition, an opening / closing portion 1413a5 for opening / closing the discharge passage 1406a is provided at the tip of the charging flicker 1413a.

  The closing solenoid 1414a is energized by the operation of the bet buttons 1114 and 1304 and operates to contract the piston (plunger) 1414a2 upward. A knob 1414a3 is attached to the tip of the piston 1414a2. The knob portion 1414a3 has the tongue piece 1414a1 extending in the radial direction of the piston 1414a2. The piston 1414a2 is provided with a coil spring 1414a4. The coil spring 1414a4 biases the main body portion 1414a5 of the closing solenoid 1414a and the knob portion 1414a3 in the direction of separating them. That is, when the energization to the closing solenoid 1414a is cut off, the piston 1414a2 extends downward by the biasing force of the coil spring 1414a4.

  When the bet buttons 1114 and 1304 are pressed, the closing solenoid 1414a is energized, and the piston 1414a2 is contracted to rotate the proximal end portion 1413a1 of the closing flicker 1413a counterclockwise in the drawing. At the same time, the tip end side portion 1413a2 of the insertion flicker 1413a rotates clockwise in the drawing to open the discharge passage 1406a, so that the game ball waiting in the ball passage 1402a can fall naturally. On the contrary, when the energization of the closing solenoid 1414a is cut off, the piston 141a2 is extended by the urging force of the coil spring 1414a4 and the proximal end side portion 1413a1 of the closing flicker 1413a is rotated clockwise in the drawing. At the same time, the tip end side portion 1413a2 of the insertion flicker 1413a rotates counterclockwise in the drawing and closes the discharge passage 1406a at the opening / closing portion 1413a5, so that the game ball cannot fall naturally.

  The passage sensor 1415a is disposed in the discharge passage 1406a and immediately downstream of the opening / closing part 1413a5 of the input flicker 1413a, and detects whether or not the game ball has been normally taken in. The passage sensor 1415a has a substantially U-shaped cross section so as to surround the tip end portion 1413a2 of the input flicker 1413a, and a light emitting element is provided on either the front side or the back side of the input flicker 1413a, and The light receiving element is provided. In addition, the light emitting element and the light receiving element are provided as a pair in the upper and lower directions and at an interval shorter than the diameter of one game ball. After the game ball is detected by the upper element 1415a1, the game balls are simultaneously detected by the upper and lower elements 1415a1 and 1415a2, and then only the lower element 1415a2 is detected within a predetermined time. When it is determined that the game ball has been properly taken in. Conversely, when the lower element 1415a2 does not detect a game ball even after a predetermined time has elapsed after detecting the game ball with the upper element 1415a1, or after the game element is detected with the lower element 1415a2, the upper side and When the lower balls 1415a1 and 1415a2 detect a game ball at the same time, and then only the upper ball 1415a1 detects a game ball, it is determined that the game ball has been inserted by unauthorized means, 1010 informs that an error has occurred and prohibits the game. Therefore, for example, it is possible to prevent fraudulent acts such as playing a game ball using a fraudulent tool. The upper element 1415a1 is in a state where the number of game balls detected by the passage sensor 1415a is one less than the number of game balls to be inserted by the game ball insertion unit 1410a (for example, 4, 9, or 14). When the final game ball is detected, the charging solenoid 1414a is de-energized, the opening / closing part 1413a5 of the charging flicker 1413a projects into the discharge passage 1406, and the game ball is configured from the ball passage 1402 to the discharge passage 1406. Yes.

  The count sensor 1416a counts the game balls thrown in by the game ball throwing unit 1410a separately from the passage sensor 1415a. The count sensor 1416a detects the passage of the game ball by an action different from that of the passage sensor 1415a. If the number of game balls counted by the count sensor 1416a is less than the number of game balls determined to have passed normally by the passage sensor 1415a, a bet error will occur. This further prevents fraud. Specifically, the passage sensor 1415a is an optical sensor, but the count sensor 1416a is a magnetic sensor. When a magnetic sensor is used as the count sensor 1416a, it can be determined whether or not the material that has passed is an iron material. Thereby, an illegal act of playing a game can be prevented even better by inserting an inexpensive resin game ball or the like that is different from a normal game ball.

  The return shutter 1420 has a plurality of window holes 1422, one corresponding to each of the plurality of game ball guide paths 1322, and the ball passages 1402 and the guide passages 1404 a, 1404 b, and 1404 c are provided to the sides of the window holes 1422. Blocking walls 1424a, 1424b and 1424c for blocking are provided. In addition, tongue pieces 1426a, 1426b, and 1426c extending toward the spherical passages 1402a, 1402b, and 1402c are provided below the window holes 1422a, 1422b, and 1422c. Each tongue piece 1426a, 1426b, 1426c is a part which guides a game ball to each window hole 1422a, 1422b, 1422c from ball passages 1402a, 1402b, 1402c. When the upper tray ball removal lever 1386 is not operated, the return shutter 1420 is at the reference position, and the game balls from each of the plurality of ball passages 1402 to the plurality of guide passages 1404 at the blocking wall 1424 of the return shutter 1420. Inflow is prohibited. On the other hand, when the upper tray ball removal lever 1386 is operated and the pressing portion 1385c of the return shutter 1420 is pressed, the return shutter 1420 moves from the reference position and passes through the window holes 1422a, 1422b, and 1422c of the return shutter 1420. The inflow of game balls from the ball path 1402 to the guide path 1404 is permitted. As a result, the game ball flows from the upper plate 1302 to the lower plate 1128 through the guide passages 1404a, 1404b, and 1404c. At this time, the movement of the return shutter 1420 from the reference position is detected by a return switch (not shown) of the return switch board 1440, and based on the detection result, it is impossible to accept operations of the 1-bet button 1114 and the max-bet button 1304. A state occurs.

  The selector relay terminal plate 1462 transmits the detection results of the passage sensor 1415a and the count sensor 1416a to the main controller 1045 described later.

  The payout device 1033 is for paying out a predetermined number of game balls by satisfying a predetermined winning condition or by pressing a ball lending button 1306 with a card inserted in a CR unit (not shown). In this embodiment, the maximum number of prize balls of the pachinko machine is 15 balls, whereas the maximum number of prize balls of the ball-type spinning game machine 1010 is 75, which is a ball-type spinning machine compared to the pachinko machine. In view of the fact that the maximum number of prize balls of the gaming machine 10 is large, more payout devices 1033 are provided than pachinko machines so that prize balls can be quickly paid out. In other words, if the pachinko machine has two payout devices 1033, the game can proceed quickly, but in the case of the ball-type spinning game machine 1010, the number of prize balls is large and all the prize balls are not paid out. In this embodiment, four payout devices 1033 are provided in the front-rear direction to speed up the payout of the winning ball so that the game can proceed without delay.

  The mounting bases 1036a and 1036b are divided into two parts, and have ball passages 1036a1 and 1036b1 connected to the upper plate guide passage 1031d and the lower plate guide passage 1031e, and ball passages 1036a2 and 1036b2 connected to the discharge passage 1031f on the right side. Have. The upper parts of one of the ball paths 1036a1 and 1036b1 are slightly inclined toward the upper dish guide path 1031d, respectively, so that it is easier to guide the game ball to the upper dish guide path 1031d than the lower dish guide path 1031e. Further, the lower part of one of the ball passages 1036a1 and 1036b1 has a tapered shape so as to straddle the upper plate guide passage 1031d and the lower plate guide passage 1031e. The other spherical passages 1036a2 and 1036b2 are configured such that the spherical passage 1036a2 on the back side merges with the spherical passage 1036b2 on the front side and continues to the discharge passage 1031f on the front side.

7A to 7C are longitudinal sectional views showing an example of the configuration of the dispensing device. When FIG. 7A is not paying out, when FIG. 7B is paying out the game balls to the upper plate, FIG. 7C shows the case where the game balls are being discharged to the outside of the gaming machine. ing.
As shown in FIG. 7A, the payout device 1033 has a resin casing including a casing 1033a and a cover (not shown).

The count sensor 1033h is arranged immediately downstream of the opening / closing portion 1033b5 of the payout flicker 1033b, and is for counting the game balls falling in the ball passage 1033d. When the number of game balls detected by the count sensor 1033h reaches a predetermined value (for example, 35, 75, 125, or 250), the payout solenoid 1033c is de-energized and the payout flicker 1033b passes through the ball path 33d. It is configured to close.

  A substantially L-shaped pressing piece 1033i for moving the knob portion 1033c3 up and down is provided below the payout solenoid 1033c. The pressing piece 1033i is rotatably attached to the support shaft 1033a3 of the casing 1033a, and presses the knob portion 1033c3 upward at the distal end portion 1033i1.

  A substantially fan-shaped operation lever 1033j (see FIG. 6) is disposed outside the casing 1033a. 7A to 7C, the operation lever 1033j can rotate around the rotation shaft 33a4. The operating lever 1033j is connected to a protrusion 1033g1 provided at the intermediate portion of the switching piece 1033g and a protrusion 1033i2 provided at the base end of the pressing piece 1033i. That is, when the operation lever 1033j is rotated, the switching piece 1033g and the pressing piece 1033i are configured to be interlocked. When the operation lever 1033j is operated counterclockwise in the drawing, as shown in FIG. 7C, the payout passage 1033e is closed by the switching piece 1033g and the ball passage 1033d and the discharge passage 1033f are communicated. On the other hand, the knob 1033c3 of the dispensing solenoid 1033c is pushed up by the pressing piece 1033i, and the dispensing flicker 1033b opens the ball passage 1033d. When the operation lever 1033j is operated as described above while preventing the game ball from flowing with the ball stop lever 1034c provided on the tank rail 1034, the game ball on the downstream side of the ball stop lever 1034c is It is discharged outside. When the payout device 1033 or the case rail 1035 fails, the payout device 1033 or the case rail 1035 is discharged in a state where the downstream game ball is discharged from the ball stop lever 1034c to the outside of the ball-type rotating game machine 1010 as described above. (See FIG. 6) can be replaced.

When the reset switch 1038b is pressed and the power switch 1038a is simultaneously turned on, the contents of the RAM are reset. When the reset switch 1038b is pressed while the power switch 1038a is turned on, the error state is reset. The stop switch 1038c is for switching whether or not the game is temporarily stopped at the end of the big bonus. The setting change key cylinder 1038d constitutes a setting change device. In the setting change device, the ball turnout rate of the ball-type spinning game machine 1010 is determined in advance in a plurality of steps (for example, 6 steps), and the ball turnout rate is set in any step. The procedure for changing the setting is as follows. First, with the power switch 1038a turned off, a setting change key (not shown) is inserted into the setting change key cylinder and rotated 90 degrees clockwise. In this state, when the power switch 1038a is turned on, the current turn-out rate (setting) of the 7-segment LED display portion 1041g (see FIG. 9) on the front surface of the game block 1040 described later is a numerical value “1” to “6”. Displayed either. Next, when the reset switch 1038b is pushed, the number displayed on the 7-segment LED display unit 1041g changes and increases by 1 (however, in the case of “6”, it returns to “1”). When the start lever 1124 (see FIG. 1) is pressed in a state where any number from “1” to “6” is displayed on the 7-segment LED display portion 1041g, the exit rate (setting) is determined.

  The CR unit connection terminal plate 1039 is electrically connected to the ball lending button 1306 (see FIG. 1) on the front surface of the ball-type spinning game machine 1010 and a CR unit (not shown), and receives a ball lending operation command from the player. This is output to the payout control apparatus 1037. Note that the CR unit connection terminal plate 39 is unnecessary in a cash machine in which game balls are rented directly from the ball lending device or the like to the upper plate 1302 (see FIG. 1) without using a CR unit.

  The payout control device 1037 and the power supply control device 1038 are configured such that a control board is accommodated in a substrate case made of a transparent resin material or the like.

  FIG. 10 is a partial exploded perspective view of an example of the rotating drum unit 1043. As shown in FIG. 10, the rotating drum unit 1043 has three rotating drums (so-called reels) L, M, and R, and each of the rotating drums L, M, and R is accommodated in the rotating drum unit frame 1043a. is there. Since each of the spinning cylinders L, M, and R has substantially the same configuration, the right spinning cylinder R will be described as an example.

  The right drum R is obtained by winding a symbol seal 1043R in which 21 symbols (identification elements) are drawn at equal intervals around the outer peripheral surface of a cylindrical skeleton member 1043R2 that forms a cylindrical cage, and the cylindrical skeleton member 1043R2 Is attached to the rotating shaft 1043R5 of the stepping motor 1043R4 for the right turn cylinder via the disk-shaped reinforcing plate 1043R3.

  The stepping motor 1043R4 for the right swirl is screwed to a motor plate 1043R6 that is suspended from the swivel unit frame 1043a. The motor plate 1043R6 has a pair of light emitting elements and light receiving elements. A position detection sensor 1043R7 is installed. A pair of photosensor elements (not shown) that constitute the rotation position detection sensor 1043R7 are arranged in the sensor casing while maintaining a predetermined interval.

  A sensor cut van 1043R9 extending in the axial direction is attached to one of the five vehicle radii 1043R8 of the cylindrical skeleton member 1043R2. The sensor cut bang 1043R9 is aligned so that it can pass through the gap between both elements of the rotation position detection sensor 1043R7. Then, every time the right cylinder R makes one rotation, the cylinder position detection sensor 1043R7 detects the passage of the tip of the sensor cut bang 1043R9, and outputs a detection signal to the main controller 1045 each time it is detected. Based on this detection signal, main controller 1045 can check and correct the angular position of right cylinder R every rotation.

  The stepping motor 1043R4 is set so that the right cylinder R makes one round by a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse; the same applies hereinafter), and the rotational position is controlled by this excitation pulse. That is, when the right turn R makes one round, 21 symbols are sequentially exposed from the lower window hole 1041b of the gaming panel 1041, so 24 pulses (= 504 pulses / 21 symbols) are required to switch from one symbol to the next. ). Then, based on the number of pulses from when the detection signal of the rotating drum position detection sensor 1043R7 is output, it is recognized which symbol is exposed from the window hole 1041b, or an arbitrary symbol is exposed from the window hole 1041b. Control can be performed. In this embodiment, a hybrid (HB) type two-phase stepping motor employing a 1-2 phase excitation method is used as the stepping motor 1043R4. The stepping motor 1043R4 is not limited to a hybrid type or two-phase, and various stepping motors such as a three-phase stepping motor and a five-phase stepping motor can be used. A drive signal (drive signal data) for the stepping motor 1043R4 is given to the motor driver 1070 (see FIG. 13) as excitation data.

  Here, the configuration of the hybrid two-phase stepping motor and the unipolar drive by the 1-2 phase excitation method will be described in detail. FIG. 12 is a schematic diagram illustrating an example of the internal structure of the stepping motor. FIG. 13 is a block diagram illustrating an example of an electrical configuration of the stepping motor. FIG. 13 is an explanatory diagram for explaining an example of the rotational excitation phase driven by the stepping motor.

  As shown in FIG. 12, the stepping motor 1043R4 includes a rotor (rotor) 1060, a first stator (stator) 1601 disposed around the rotor 1060, a second stator 1602, a first stator 1603, a first stator 1603, and a first stator 1603. Four stators 1604, a first wiring W1 that goes around the first stator 1601 and the third stator 1063, a third wiring W1 that goes around the first stator 1601 and the third stator 1063, and a second stator 1602 and a fourth stator 1064. A second wiring W2 that circulates and a fourth wiring W4 that circulates the second stator 1602 and the fourth stator 1064 are provided.

  The rotor 1060 includes a front rotor 60a, a back rotor 1060b, and a cylindrical permanent magnet (not shown) arranged between the front rotor 1060a and the back rotor 60b. The front rotor 1060a and the back rotor 1060a are magnetized in opposite polarities by the magnetic force of the cylindrical permanent magnet. In this embodiment, the front rotor 1060a is magnetized to the N pole, and the back rotor 1060a is magnetized to the S pole. 63 salient poles are formed at equal intervals on the periphery of the front rotor 1060a and the back rotor 1060b. For convenience of explanation, FIG. 12 shows a case where there are 15 salient poles. The front rotor 1060a and the back rotor have a pitch interval between the salient poles so that each salient pole provided around the back rotor 1060b is positioned between the salient pole (small teeth) of the front rotor 1060a and the salient pole. Relative displacement by 1/2. The rotation shaft 1043R5 (see FIG. 10) rotates with the rotation of the rotor 1060.

  Each stator 1601 to 1604 is opposed to both the front rotor 1060a and the back rotor 1060b, and three salient poles are provided at the front end of the rotor 1060 side of each stator 1601 to 1604 and the front rotor 1060a and the back rotor. It is formed at the same pitch interval as the salient poles at 1060b. Each of the stators 1601 to 1604 is magnetized when a current is passed through the wound wirings W1 to W4 and functions as a magnetic pole.

  A portion wound around the first stator 1601 in the first wiring W1 functions as an exciting coil of the first stator 1601, and a portion wound around the third stator 1603 functions as an exciting coil of the third stator 1603. In the first wiring W1, the winding direction with respect to the first stator 1601 and the winding direction with respect to the third stator 1603 are reversed, and when a current flows through the first wiring W1, the first stator 1601 The third stator 1603 is magnetized with a reverse polarity. In driving the stepping motor 1043R4, only a current in a certain direction flows through the first wiring W1. In the third wiring W3, a portion wound around the first stator 1601 functions as an exciting coil of the first stator 1601, and a portion wound around the third stator 1603 functions as an exciting coil of the third stator 1603. . In the third wiring W3, the winding direction with respect to the first stator 1601 and the winding direction with respect to the third stator 1603 are opposite, and when a current is passed through the third wiring W3, The third stator 1603 is magnetized with a reverse polarity. In driving the stepping motor 1043R4, only a current in a constant direction opposite to the first wiring W1 flows through the third wiring W3. A method of winding the same stator around a pair of wires, such as the first wire W1 and the third wire W3, is generally referred to as “bifilar winding”. Since the second wiring W2 and the fourth wiring W4 are the same as the first wiring and the third wiring, detailed description thereof will be omitted. A method in which a current is allowed to flow only in a predetermined direction in driving the stepping motor 1043R4, such as the wirings W1 to W4, is generally referred to as “unipolar driving”. Such a stepping motor 1043R4 is represented by a circuit symbol as shown in FIG. In FIG. 13, a coil L1 represents the whole of the exciting coil of the first stator 1601 and the exciting coil of the third stator 1603 by the first wiring W1. The other coils L2 to L3 are similar to the case of the coil L1.

  In this specification, as shown in FIG. 14, an excitation phase for exciting the first stator 1601 and the third stator 1603 to the S pole and the N pole respectively by flowing a current through the first wiring W <b> 1 is “A phase”. The excitation phase is referred to as “a kind of rotation excitation phase and basic rotation excitation phase”, and an excitation phase for exciting the first stator 1601 and the third stator 1603 to the N pole and the S pole respectively by flowing a current through the third wiring W3 is referred to as “reversed A phase”. "(A kind of rotation excitation phase and basic rotation excitation phase)", and an excitation phase for exciting the second stator 1602 and the fourth stator 1604 to the S-pole and the N-pole respectively by passing a current through the second wiring W2 is referred to as "B-phase". ”(A kind of rotation excitation phase and basic rotation excitation phase), and an excitation phase for exciting the second stator 1602 and the fourth stator 1604 to the N-pole and the S-pole respectively by passing a current through the fourth wiring W4 is“ inverted B ”. Phase "(times It will be referred to as the kind of the excitation phase and the basic rotation excitation phase). Also, the excitation phase that excites the A phase and the B phase together is called “(A + B) phase” (a kind of rotational excitation phase and quasi-rotation excitation phase), and the B phase and the inverted A phase are excited together. The excitation phase to be excited is referred to as “(B + reversal A) phase” (a kind of rotational excitation phase and quasi-rotation excitation phase), and the excitation phase that excites the reversed A phase and reversed B phase collectively as “(reversed A + reversed B)”. ) Phase "(a kind of rotational excitation phase and quasi-rotation excitation phase), and the excitation phase that energizes the inverted B phase and the inverted A phase together is called" (inverted B + A) phase "(rotation excitation phase and quasi-rotation). This is called a kind of excitation phase. In FIG. 14, the mark “−” means that excitation is not performed. In general, each of the A phase, the B phase, the inverted A phase, and the inverted B phase is a basic excitation phase that excites by passing a current through one of the various wirings W1 to W4. On the other hand, an excitation phase that energizes two types of one-phase excitation phases at a time by passing a current through two of the various wirings W1 to W4 as in the (A + B) phase is “2”. This is referred to as “phase excitation phase”.

  As shown in FIG. 14, the stepping motor 1043R4 is driven via the motor driver 1070 when an excitation phase information signal including excitation phase type information is transmitted from the input / output port 1045a4 of the main control board 1045a. The Specifically, when the motor driver 1070 receives an excitation phase information signal including, for example, information on the A phase, the motor driver 1070 changes the potential of the A terminal to the ground potential (0 V), and until the next excitation phase information signal is received. This state is maintained. As a result, a power supply voltage (for example, a + 24V DC voltage) is applied to the coil L1. The same applies to excitation signals including information on other excitation phases. For example, when an excitation signal including information on both the A phase and the B phase is received, the potentials of the A terminal and the B terminal are changed to the ground potential, and the power supply voltage is applied to both the coil L1 and the coil L2. Is done.

  The main control device 1045 is responsible for the main control of the ball-type spinning game machine 1010. Specifically, the main control device 1045 receives a signal from the start lever 1124 and receives a winning combination (big bonus, regular bonus, small role, replay). And a command signal is issued to the sub-control device 1047 and the payout control device 1037 based on the lottery result. As shown in FIG. 15, the main controller 1045 has a configuration in which a CPU 1045a1 that controls the main control, a ROM 1045a2 that stores a game program, a RAM 1045a3 that stores necessary data according to the progress of the game, and various devices are connected. A main control board 1045a including an output port 1045a4, a random number generation circuit 1045a5 used for various lotteries, a clock circuit 1045a6 used for time counting and synchronization, and a transparent resin that accommodates the main control board 1045a A substrate case 1045b (1045b1, 1045b2) (see FIG. 8) made of a material or the like is used.

  The sub-control device 1047 is based on a command signal (command) issued from the main control device 1045, and a light-emitting device for game effect (not shown) that is covered with various LED cover portions such as the LED cover portion 1104 (see FIG. 1). LED) is turned on and blinking, sound effects emitted from the upper and lower speakers 1106 and 1204 (see FIG. 1), and the display mode displayed on the liquid crystal display device 1042 are controlled. The configuration of the sub-control device 1047 is the same as that of the main control device 1045. The sub-control including the CPU for controlling the various LEDs, the upper and lower speakers 1106 and 1204, and the liquid crystal display device 1042, and other ROM, RAM, input / output ports, and the like. A substrate 1047a and a substrate case 1047b (1047b1, 1047b2) made of a transparent resin material or the like for accommodating the sub-control substrate 1047a.

(Control system for ball-type spinning machine)
A control system of the ball-type spinning machine 1010 will be described. FIG. 15 is a block diagram showing an example of an electrical configuration of a ball-type spinning machine.

  As shown in FIG. 12, the main control board 1045a functions as a control unit configured as a microcomputer centering on a CPU 1045a1 which is an arithmetic processing unit, and a ROM (or flash memory) 1045a2 for temporarily storing a processing program. A working RAM 1045a3, an input / output port 1045a4, and the like for storing data are connected to the CPU 1045a1 via an internal bus.

  The input / output port 1045a4 of the main control board 1045a has a reset signal from the reset switch 1038b, a setting signal from the setting key switch 1038d1, a 1-bet signal from the bet button 1114, a maximum bet signal from the max bet button 1304, and a selector 1400. The auxiliary passage detection signals from the count sensors 1416a1, 1416b1, 1416c1 for detecting the game balls taken in, and the upper elements 1415a1, 1415b1, 1415c1 in the passage sensors 1415a, 1415b, 1415c for detecting the game balls taken in by the selector 1400 Upstream passage detection signals from the lower element passage sensors 1415a2, 1415b2, 1415c2 in the passage sensors 1415a, 1415b, 1415c, Fluctuation start signal from the moving lever 1124, stop signal from each of the spinning cylinder stop buttons 1126L, 1126M, 1126R, detection signal from the spinning cylinder position detection sensors 1043L7, 1043M7, 1043R7, a count for detecting a game ball dispensed from the dispensing device 1033 A count signal based on the count switch signal from the sensor 1033h, a game ball detection signal from the ball break detection device 1035b for detecting a game ball in the case rail 1035, a paying out signal indicating the payout period, and the like are input.

  Further, from the input / output port 1045a4 of the main control board 1045a, the closing solenoids 1414a, 1414b, 1414c based on the betting signals from the betting buttons 1114, 1304, the closing solenoids based on the count values of the passage sensors 1415a, 1415b, 1415c. 1414a, 1414b, 1414c drive stop signals, fluctuation start signals from the start lever 1124, and drive signals for the spinning stepping motors 1043L4, 1043M4, 1043R4 based on stop command signals from the spinning cylinder stop buttons 1126L, 1126M, 1126R, etc. Is output. Control signals for controlling the contents of effects displayed on the liquid crystal display device 1042, sound effects emitted from the speakers 1106 and 1204, lighting and blinking of various light emitting devices (LEDs) covered with the upper LED cover 1104, etc. Is output to the sub-control board 1047a.

  The above-described CPU 1045a1 includes a ROM 1045a2 that stores various control programs executed by the CPU 1045a1 and fixed value data, and a work area that temporarily stores various data when executing the control program stored in the ROM 1045a2. In addition to the working RAM 1045a3 for securing the above, various processing circuits necessary for the ball-type spinning machine 1010 such as a timer circuit and a data transmission / reception circuit such as an interrupt circuit as well known are incorporated, although not shown. ing.

  The ROM 1045a2 and the RAM 1045a3 constitute a main memory, and a processing program (including an output control information generation processing program) for executing various processes is stored in the ROM 1045a2 described above as a part of the processing program. In the RAM 1045a3, a plurality of work areas are secured functionally. As is well known, in addition to a stack memory (stack memory area) for storing the value of the program counter provided in the CPU 1045a1, in this example, a power failure flag memory for storing a power failure flag and a stack for storing a stack pointer Pointer storage memory, checksum correction value memory for storing correction values related to the checksum of data stored in the RAM 45a3, and memory such as a power recovery command buffer and power recovery command counter used during power recovery Area is secured.

  In addition to I / O devices such as the sub-control board 1047a, the input / output port 1045a4 is an external device capable of transmitting information to a gaming machine management device (not shown) such as a computer for a hall manager, an external information display device, The centralized terminal board, the power failure monitoring circuit 1038f provided on the power supply control board 1038 ′, the closing solenoids 1414a, 1414b, 1414c, the payout control board 1037a, and the like are electrically connected.

  The power supply control board 1038 ′ is equipped with a power supply unit 1038 e that supplies driving power to each electronic device of the ball-type spinning machine 1010 including the main control board 1045 a, the power failure monitoring circuit 1038 f described above, and the like. The power failure monitoring circuit 1038f monitors the power-off state, and generates a power failure signal not only at the time of a power failure but also when the power switch 1038a is turned off. For this reason, the power failure monitoring circuit 1038f monitors the stabilized drive voltage of 24 VDC output from the power supply unit 1038e, and determines that the power has been disconnected when the drive voltage drops below, for example, 22 volts. A signal is output. The power failure signal is supplied to each of the CPU 1045a1 and the input / output port 1045a4, and the CPU 1045a1 recognizes this power failure signal to execute the power failure process. The power supply unit 1038e is configured to output a stabilized voltage of 5 volts used as a drive voltage in a control system such as the main control board 1045a even when the output voltage is reduced to less than 22 volts. As a time during which the stabilization voltage is output, a sufficient time is secured to execute the power failure process by the main control board 1045a.

  Further, when the reset signal is transmitted from the reset switch 1038b at the same time when the stabilization drive voltage is supplied from the power supply unit 1038e, the main control board 1045a erases the information written in the RAM 1045a3 and stabilizes from the power supply unit 1038e. When a reset signal is transmitted from the reset switch 1038b in a state where the drive voltage is supplied, the error state is reset.

  Furthermore, when the power is turned on after the setting key switch 1038d1 is turned on when the power is turned off, that is, when the power is turned on after the setting key is inserted into the setting change key cylinder 1038d and rotated. A state in which the exit rate of the trunk game machine 10 can be changed occurs. In this state, when a reset signal is transmitted from the reset switch 1038b, the bonus probability and the small role probability of the ball-type spinning game machine 1010 are changed, and the change result is represented by the numbers “1” to “6”. It outputs to 7 segment LED display part 1041g (refer FIG. 9). Then, when a setting confirmation signal is received from the start lever 1124 in a state in which any number from “1” to “6” is displayed on the 7-segment LED display unit 1041g, the turn-out rate of the ball-type rotating game machine 1010 Confirm (Setting).

  The payout control board 1037a has a configuration substantially similar to that of the main control board 1045a, and includes a CPU, a ROM (or flash memory) for storing a processing program, a working (working) RAM for temporarily storing data, Input / output ports and the like are connected to the CPU via an internal bus.

  A control process executed on the main control board 1045a will be described. The control processing of the main control board 1045a is roughly divided into main processing that is activated in response to power recovery by external power supply restart or power switch 1038a being turned on, and interrupt processing that interrupts the main processing. The For convenience of explanation, after describing the interrupt process, the main process will be described. As interrupt processing, there are power failure interrupt processing for interrupting in response to reception of a power failure signal at the NMI terminal, and timer interrupt processing for periodically interrupting by measuring time with a timer.

  First, the power failure interrupt process will be described. When a power failure occurs, a power failure signal is generated by the power failure monitoring circuit 1038f of the power control board 1038 'and output to the main control board 1045a. In main control board 1045a, the NMI terminal of CPU 1045a1 receives a power failure signal, and an interrupt process (not shown) (hereinafter referred to as “power failure interrupt process”) is executed in which a power failure flag is set in response to the reception of the power failure signal. In the power failure interrupt process, first, the register data currently used is saved in a backup area in the RAM 1045a3 ("register save process"). After the register saving process, the power failure flag is set (“power failure flag setting process”). The power failure flag is information representing the occurrence of a power failure state held in a specific area in the RAM 45a3. After the power failure flag setting process, the CPU 45a1 is notified of the end of the process in its own interrupt ("interrupt end declaration process"). After the interrupt end declaration process, the register data saved in the backup area of the RAM 1045a3 in the register saving process is restored to the register of the CPU 45a1 ("register restoring process"). After the register restoration process, a new interrupt is permitted (“interrupt permission process”). The power failure interrupt process ends when the interrupt permission process is completed. If the power failure flag setting process can be performed without destroying the data in the register in use, the register saving process and the register restoring process can be omitted.

  Next, timer interrupt processing will be described. FIG. 16 is a flowchart showing an example of timer interrupt processing in the main control board 1045a. In the main control board 1045a, timer interrupt processing is periodically performed. In this embodiment, the timer interrupt process is substantially performed at a period of 1.49 ms [milliseconds].

  In the timer interrupt process, first, information on all registers used in the normal process in the main process described later is stored in the backup area of the RAM 1045a3 ("register save process" S2101). After the register saving process S2101, it is confirmed whether or not a power failure flag is set (S2102). When the power failure flag is set, the backup process S2103 is executed.

  In the backup process S2103, first, it is determined whether or not the transmission of various commands stored in the ring buffer has been completed. If the transmission of these commands has not ended, the backup process S2103 is temporarily ended and control returns to the timer interrupt process. This is control for completing the transmission of the command before starting the backup process S2103. On the other hand, when the transmission of these commands is completed, the value of the stack pointer of the CPU 1045a1 is saved in the backup area in the RAM 1045a3 ("stack pointer saving process"). After the stack pointer saving process S2102, a RAM determination value, which will be described later, is cleared, and the output state of the output port in the input / output port 45a4 is cleared, and all actuators (not shown) are turned off ("stop process"). After the stop process, a new RAM determination value is calculated and stored in the backup area (“RAM determination value storage process”). The RAM determination value is a 2's complement of the checksum value in the work area of the RAM 1045a3. Here, the 2's complement of the tick sum value is a value generated when each digit (bit) of the check sum value is inverted in binary representation. In this case, the value obtained by adding 1 to the exclusive OR (“FFFF”) of the checksum value of the RAM 1045a3 and the RAM determination value is “0”. In this embodiment, the complement of the checksum value is used as the RAM determination value. However, in the present invention, the checksum value itself may be used as the RAM determination value. After the RAM determination value storage process, access to the RAM 1045a3 is prohibited ("RAM access prohibition process"). Thereafter, an infinite loop is entered in preparation for the case where the processing cannot be executed due to complete interruption of the internal power. Note that, for example, when the power failure flag is erroneously set due to noise or the like, although not shown, it is confirmed whether the power failure signal is still input before entering the infinite loop. If the power failure signal is not output, the internal power supply is restored, so that writing to the RAM 1045a3 is permitted, the power failure flag is released, and the process returns to the timer interrupt process. On the other hand, if the power failure signal is continuously input, an infinite loop is entered (not shown).

  As described above, it is determined whether or not the command transmission is completed at the initial stage of the backup process S2103, and when those transmissions are not completed, the transmission process is prioritized. By adopting a configuration in which the backup process S2103 is executed after the command transmission process is completed, it is not necessary to construct a power failure processing program that also considers that the backup process is executed during the command transmission. As a result, it is possible to simplify the program related to the processing at the time of power failure and to reduce the capacity of the ROM 1045a2.

  The power supply unit 1038e of the power supply control board 1038 ′ outputs backup power used as drive power for the control system for a sufficient time to complete the power failure interrupt process and the backup process even after a power failure occurs. . With this backup power, backup processing of power failure interrupt processing and timer interrupt processing is performed. In this embodiment, backup power is continuously output for 30 ms [milliseconds] after the occurrence of a power failure.

Returning to the description of the timer interrupt process, as shown in FIG. 16, when it is determined in the determination process S2102 that the power failure flag is not set, the watchdog timer for monitoring the occurrence of malfunction is initialized. Then, an interrupt permission is issued to the CPU 1045a1 itself ("interrupt end declaration process" S2104).
After the interrupt end declaration process S2104, the left stepping motor 1043L4 for rotating the left cylinder L, the middle stepping motor 1043M4 for rotating the middle cylinder M, and the right stepping motor 1043R4 for rotating the right cylinder R The drive is controlled ("left stepping motor control process" S2105, "middle stepping motor control process" S2106, "right stepping motor control process" S2107).

  Here, the stepping motor control process will be described. Since the left stepping motor control process S2105, the middle stepping motor control process S2106, and the right stepping motor control process S2107 are substantially the same process, only the right stepping motor control process S2107 will be described. FIG. 17 is a flowchart illustrating an example of the right stepping motor control process.

  In the right stepping motor control process S2107, as shown in FIG. 17, it is first determined whether or not the value of the right wait timer is “0” (S101). The “right wait timer” is a software timer that monitors the excitation time (interrupt count) in the right stepping motor 1043R4. When the value of the right wait timer is “0”, the excitation state for the right stepping motor 1043R4 is This means that a change is necessary. If the right wait timer is a value other than “0”, it means that the current excitation state is maintained. If the value of the right wait timer is not “0”, the value of the right wait timer is updated to a new value obtained by subtracting 1 from the current value (“wait timer update process” S102), and the right stepping motor control is performed. Processing S2107 ends.

  When it is determined in the determination process S101 that the value of the right wait timer is “0”, it is determined whether or not the value of the right acceleration counter is “0” (S103). The “right acceleration counter” is a software counter that monitors the transition of the rotational excitation phase in the rotational driving state of the right stepping motor 1043R4, and is in a predetermined range (specifically, “26” to “1” )) And takes a predetermined value (specifically, “1”) in the constant speed driving state. The right acceleration counter takes a predetermined value (“0”) different from all values in the acceleration driving state and the constant speed driving state in the deceleration driving state. The value of the right acceleration counter is set to a large value exceeding “0”, specifically “26” in the rotation initialization process S2307 (see FIG. 20) of the normal game process of the main control board 1045a described later. Driving of the right stepping motor 1043R4 is substantially started by the setting.

  When it is determined in the determination process S103 that the value of the right acceleration counter is “0”, the value of the right acceleration counter is updated (“acceleration counter setting process” S104). In the right acceleration counter setting process S104, if the value of the right acceleration counter is “1”, the value is maintained. If the value of the right acceleration counter is not “1”, a new value obtained by subtracting 1 from the current value is maintained. Set to

  After the acceleration counter setting process S104, the value of the right wait timer is set to excitation time information corresponding to the value of the right acceleration counter (“wait timer setting process” S105). Here, the setting of the right wait timer will be specifically described. FIG. 18A is an explanatory diagram for describing an example of an acceleration excitation time information sequence and an example of a reference method thereof. In the ROM 1045a2 of the main control board 1045a, the acceleration excitation time information sequence shown in the column “Excitation time” in FIG. 18A is held in a continuous range of a predetermined range. In the wait timer setting process S105, in the acceleration drive state, for example, if the value of the right acceleration counter is “25”, “130” is set in the right wait timer as excitation time information. Thus, the excitation time of the first one-phase excitation phase (specifically, the A phase or the B phase) in the acceleration order is determined. On the other hand, in the constant speed driving state, the value of the wait timer is always set to “1”. The constant speed excitation time information (“1”) is held directly in the program in the ROM 1045a2 of the main control board 1045a.

  After the wait timer update process S105, the rotation excitation phase information is updated ("rotation excitation phase information update process" S106). In the rotation excitation phase information update process S106, the rotation excitation phase next to the current rotation excitation phase is selected according to the rotation excitation sequence, and right excitation phase information corresponding to the selected rotation excitation phase is set. Here, the update of the right excitation phase information will be specifically described. FIG. 1B is an explanatory diagram for explaining an example of a rotation excitation phase information sequence and an example of a reference method thereof. In the ROM 1045a2 of the main control board 1045a, the rotation excitation phase information sequence shown in the “Rotation excitation phase information” column of FIG. 18B is held in a continuous range of a predetermined range. In the binary display of the rotational excitation phase information (value in parentheses in the figure), the 0th bit (LSB: rightmost bit in the figure) indicates whether or not the A phase is excited, and the first bit is the B phase. The third bit represents the presence or absence of inverted A phase excitation, the fourth bit represents the presence or absence of inverted B phase excitation, and if the value of each bit is “1”, the corresponding phase It means excitation, and “0” means no excitation of the corresponding phase. In the rotation excitation phase information update processing S106, the right excitation phase pointer is updated, and the rotation excitation phase information pointed to by the right excitation phase pointer is selected as the right rotation excitation phase state with reference to the rotation excitation phase information sequence. The right excitation phase pointer cyclically takes an integer in a predetermined range of values (specifically, “0” to “7”). For example, when the right excitation phase pointer is “0”, “01H” corresponding to the A phase is selected as the right excitation phase information. Note that the selected right excitation phase information is output to the motor driver 1070 in port output processing S2115 described later.

  After the rotational excitation phase update process S106, the value of the right symbol offset is updated to a new value obtained by adding 1 to the current value ("design offset update process" S107). The “right symbol offset” is information for identifying the displacement angle in the symbol, and in cooperation with the “right symbol number”, the displacement angle of the right cylinder R from the reference rotation position of the right cylinder R is identified. . That is, the displacement angle of the right cylinder R is designated by the right displacement angle information (for example, [10, 12]) based on the combination of the right symbol number and the right symbol offset [right symbol number, right symbol offset value]. . The right displacement angle information corresponding to the reference rotation position is [0, 0].

  After the symbol offset update process S107, it is determined whether or not the rotation of the rotating cylinder R has reached the steady rotation based on the reference position detection signal from the right rotating cylinder position detection sensor 1043R7. The number and the value of the right symbol offset are corrected to values at the reference rotation position (“rotation position correction process” S108). Although not shown, reacceleration is required to restart rotation when the rotating cylinder is not rotating normally based on the reference position detection signal from the right rotating cylinder position detection sensor 1043R7, the right symbol number, and the right symbol offset. If the determination is affirmative, re-acceleration processing is performed.

  After the rotational position correction process S108, the right symbol number is updated as necessary ("symbol number update process" S109). In the symbol number update process S109, when the value of the right symbol offset is larger than a predetermined maximum value (specifically, “23”), the right symbol number is changed to a number obtained by adding 1 to the current number. At the same time, the value of the right symbol offset is changed to a predetermined minimum value (specifically, “0”).

  After the symbol number update process S109, it is determined whether to stop driving the right stepping motor or not (S110 to S112). In the stop start determination, whether the right symbol offset value is less than “3” (first condition), whether the right symbol number matches the right stop symbol number (second condition), the updated current rotation If the excitation phase is one-phase excitation phase, specifically, whether the value of the right excitation phase pointer is an even number (third condition) is determined, an affirmative determination is made when all of the first to third conditions are satisfied A negative determination is made if any one of the first condition to the third condition is not satisfied. If the value of the right excitation phase pointer is an even number, one phase excitation phase is selected. If the value of the right excitation phase pointer is an odd number, the two phase excitation phase is selected. In the start determination, when the right displacement angle information is [right stop symbol number, 0] or [right stop symbol number, 2], that is, A phase excitation or B immediately after the right symbol number is updated to the stop symbol number. An affirmative determination is made when phase excitation is selected. The right stop symbol number is set in a right cylinder stop process S2624 (see FIG. 23) in a rotation control process S2309 (see FIGS. 20 and 23) of the main control board 1045a described later.

  If a negative determination is made in the stop start determination (S110 to S112), the right stepping motor control process S2107 ends. On the other hand, if an affirmative determination is made, the right stepping motor 1043R4 is The drive stops.

  When the drive of the right stepping motor 1043R4 is stopped, in order to cancel the control of the right acceleration counter, the value of the right acceleration counter is set to a predetermined value (specifically, “0”) (“acceleration counter canceling process”) S113). Further, the value of the right deceleration counter is set to a predetermined value (specifically, “2”) (“deceleration counter setting process” S114). The “right deceleration counter” is a software counter that monitors the transition of the stop excitation phase in the deceleration driving state of the right stepping motor 1043R4, and is in a predetermined range (specifically, “2” to “0” in the deceleration driving state). )). The right deceleration counter takes a value of “0” even in the non-excitation state after the deceleration drive state ends.

  After the deceleration counter setting process S114, the value of the right wait timer is set to excitation time information corresponding to the value of the right deceleration counter ("wait timer resetting process" S115). Thus, in the wait timer resetting process S115, the value of the right wait timer once set in the wait timer setting process S105 is forcibly reset to a predetermined value. Here, the setting of the right wait timer will be specifically described. FIG. 18C is an explanatory diagram for describing an example of a deceleration excitation time information sequence and an example of a reference method thereof. In the ROM 1045a2 of the main control board 1045a, the deceleration excitation time information sequence shown in the “Excitation time” column of FIG. 18A is held in a continuous range of a predetermined range. In the wait timer resetting process S115, since the value of the right deceleration counter is “2”, “11” is reset in the right wait timer as excitation time information. Thereby, the excitation time of the first all-phase excitation phase in the deceleration order is set.

  After the wait timer resetting process S115, all-phase information (specifically, “0FH (= 0000111B)”) is set as the right excitation phase information (“all-phase setting process” S116). As can be seen from the binary display of all-phase information, all phases are energized at once for the A phase, B phase, inverted A phase, and inverted B phase (all of the rotation excitation phases or all of the basic rotation excitation phases). Excitation phase. As a result, in the all-phase setting process S116, the excitation phase (specifically, the A phase or the B phase) once selected in the rotational excitation phase setting process S105 is forcibly changed to all phases. This all-phase information is directly held in the program in the ROM 1045a2 of the main control board 1045a.

  When it is determined in the determination process S103 that the value of the right acceleration counter is “0”, it is determined whether or not the value of the right deceleration counter is “0” (S117). When the value of the right deceleration counter is not “0”, the value of the right deceleration counter is updated to a new value obtained by subtracting 1 from the current value (“deceleration counter update process” S118). After the deceleration counter update process S118, it is determined whether or not the value of the right deceleration counter is “0” (S119).

  When the value of the right deceleration counter is not “0”, specifically, when it is “1”, the value of the right wait timer is referred to the stop excitation time information sequence and the value of the right deceleration counter (“1”). ) According to the type of affirmative determination in the stop start determination processing (S110 to S112), and is set to excitation time information (specifically, “3”) according to Information (specific phase information and basic excitation phase information) or B phase information is set as right excitation phase information ("specific phase setting process" S121). Specifically, in the A phase information setting process, the rotational excitation phase information in the rotational excitation phase information sequence pointed to by the current excitation phase pointer is selected as the right excitation phase information. Accordingly, in the stop start determination process (S110 to S112), when the condition of [right stop symbol number, 0] is satisfied, the A phase (basic excitation phase) is selected and the A phase information (basic information as the right excitation phase information) is selected. When the excitation phase information) is set and the condition of [right stop symbol number, 2] is satisfied, the B phase is selected and the B phase information is set as the right excitation phase information. Upon completion of the A-phase information setting process S121, the right stepping motor control process S2107 ends.

  If the value of the right deceleration counter is “0” in the determination process S119, the excitation time corresponding to the value of the right deceleration counter (“0”) is determined by referring to the stop excitation time information sequence. Information (specifically, “146”) (“wait timer setting process” S122), and all phase information (“0FH”) is set as the right excitation phase information (“all phase setting process” S123). . This all-phase information is also directly held in the program in the ROM 1045a2 of the main control board 1045a.

  If it is determined in the determination process S117 that the value of the right deceleration counter is “0”, the right stepping motor 1043R4 is in an excited state (specifically, because the deceleration driving state is completed or has been completed). In the case of the all-phase excitation state), the state is shifted to the non-excitation state, and when the state is already the non-excitation state, the state is maintained ("de-excitation processing" S124). Upon completion of the group maintenance process S124, the right stepping motor control process S2107 ends. As described above, the right stepping motor control process S2107 includes the determination process S101 to the deexcitation process S124.

  Returning to the description of the timer interrupt process, as shown in FIG. 16, after various stepping motor control processes S2105 to S2107, a change in the state of the switch in the various apparatuses connected to the input / output port 1045a4 is monitored ( “Switch reading process” S2108). After the switch reading process S2108, the sensor state change in various devices connected to the input / output port 1045a4 is monitored ("sensor monitoring process" S2109). After the sensor monitoring process S2109, various counter values and various timer values are subtracted ("timer subtraction process" S2110). After the timer subtraction process S2110, the bet number and the acquired ball number are output to the external concentration terminal board in order to count the difference ball number (difference between the total number of bets and the total number of acquisitions) ("difference ball counting process" S2111). . After the difference ball counting process S2111, various commands accumulated in the ring buffer are transmitted to the sub control board 47a ("command output process" S2112). After the command output process S2112, segment data displayed on the 7-segment LED display unit 1041g, the acquired number display device, and the like are set ("segment data setting process" S2113). The segment data set in the segment data setting process S2113 is transmitted to a predetermined segment data display device in the 7-segment LED display unit 1041g or the like (“segment data display process” S2114). Accordingly, the 7-segment LED display unit 1041g and the like display numbers, characters, symbols, and the like corresponding to the received segment data. Data is output from the input / output port 1045a4 to the I / O device ("port output processing" S2115). After the port output process S2115, the data of each register saved in the backup area in the register save process S2101 is restored to the corresponding register in the CPU 1045a1 ("register restore process" S2116). After the register restoration process S2116, the next timer interrupt is permitted ("interrupt permission process" S2117). A series of timer interrupt processing is completed through the above processing.

  The main process in the main control board 1045a will be described. FIG. 19 is a flowchart showing main processing of the main control board 1045a. The main process of the main control board 1045a is executed when returning from the power failure state.

  In the main process of the main control board 1045a, first, an initial value of the stack pointer is set ("stack pointer initial setting process" S2201). After the stack pointer initial setting process S1201, an interrupt mode permitting the interrupt process is set ("interrupt mode setting process" S2202). After the interrupt mode setting process S2202, various settings for the register group, the I / O device, and the like in the CPU 45a1 are performed ("register setting process" S1203).

  After the register setting process S2203, a setting key is inserted into the setting key switch 1038d1, and it is determined whether or not a predetermined operation (such as a right rotation operation) is performed (S2204). If it is determined that the setting key is operated, one probability setting selected from a plurality of predetermined probability settings (in this embodiment, six settings from “setting 1” to “setting 6”) The data in all the areas of the RAM 1045a3 excluding the predetermined area that holds the set value is forcibly cleared ("forced RAM clear processing" S2205). After the forced RAM clearing process S2205, the current setting value can be reset (resetting the setting) ("probability setting selection process" S2206). In changing the set value, the operation of the reset switch 1038b and the operation of the start lever 1124 are used. After the probability setting selection process S2206, the process proceeds to the normal game process.

  If it is determined in the determination process S2204 that the setting key switch 1038d1 is not operated, is the set value of the selected probability setting within a predetermined range (“1” to “6”)? It is determined whether or not (S2207). Note that the set value takes only a value within a predetermined range unless an abnormal situation such as mechanical or electrical destruction of the RAM 45a3 occurs between the occurrence of a power failure state and the return from the power failure state. Absent. If the set value is within a predetermined range, it is determined whether or not a power failure flag is set (S2208). When the power failure flag is set, the checksum value of the work area of the RAM 45a3 is newly calculated, and it is determined whether or not the new checksum value is normal (S2209). The new checksum value is normal means that the new checksum value and the checksum value before the occurrence of the power failure state are the same, that is, the new checksum value and the RAM determination held in the backup area of the RAM 45a3. It means that the value obtained by adding 1 to the exclusive OR with the value is “0”. This value is “0” when the new checksum value and the checksum value before the occurrence of the power failure are the same, and other than “0” when they are different. Unless an abnormal situation such as mechanical or electrical destruction of the RAM 45a3 occurs between the occurrence of a power failure state and the return from the power failure state, this value is not “0”.

  If it is determined in the determination process S2207 that the set value of the probability setting is not within the predetermined range, if it is determined in the determination process S2208 that the power failure flag is not set, or a new checksum is determined in the determination process S2209 When it is determined that the value obtained by adding 1 to the exclusive OR of the value and the RAM determination value is other than “0”, the interrupt is prohibited (“interrupt prohibition setting process” S2216). After the interrupt inhibition setting process S2216, all output ports of the input / output port 1045a4 are cleared, and all actuators connected to the input / output port 1045a4 are turned off ("all output port clear process" S2217). After the all output port clear process S2217, a process for notifying the occurrence of an error is performed ("error notification process" S2218). This error notification state continues until the reset switch 1038b is operated.

  If it is determined in the determination process S2209 that the new checksum value is normal, the value of the stack pointer stored in the backup area is written to the stack pointer of the CPU 1045a1, and the value of the stack pointer is before the occurrence of the power failure state. ("Stack pointer return process" S2210). As a result, after returning from the power failure state, it is possible to resume from the process interrupted by the occurrence of the power failure state. After the stack pointer recovery process S2210, a power recovery command indicating recovery from the power failure state is set ("power recovery command setting process" S2211). As a result, the power recovery command is transmitted to the sub control board 1047a. After the power recovery command setting process S2211, the state of the stop changeover switch 1038c is stored in a predetermined area of the RAM 1045a3 ("game form setting process" S2212). After the game form setting process S2212, the sensor values of various devices are initialized ("sensor initialization process" S2213). After the sensor initialization process S2213, the power failure flag is canceled ("power failure flag cancellation process" S2214). If a power failure occurs during payout after the power failure flag release process S2214, a payout command for resuming payout is set ("payout command setting process" S2215). After the payout command setting process S2215, the process is resumed from the process at the address before the occurrence of the power failure indicated by the stack pointer. Specifically, the interrupt end declaration process S2104 after the backup process S2103 (see FIG. 16) in the timer interrupt process described above is executed.

  The normal process for performing the main control related to the game at the normal time will be described. FIG. 19 is a flowchart showing an example of a normal game process executed on the main control board 1045a. The normal game process of the main control board 1045a is executed after the end of the probability setting process S2206 (see FIG. 19) in the main process. In addition, after the payout command setting process S2215 ends, the normal game process is executed halfway.

  In the normal game process, as shown in FIG. 15, first, interrupt permission is set ("interrupt permission setting process" S2301). After the interrupt permission setting process S2301, the state of the stop change switch 1038c for determining the game form is stored in a predetermined area of the RAM 1045a3 (“game form setting process” S2302). The game form setting process S2302 is the same process as the game form setting process S2212 (see FIG. 19) in the main process. After the game form setting process S2302, the process proceeds to the loop process described below. In the following, a case where a continuous game is in progress will be described.

  In the loop process, the data in the area holding information that changes for each game in the RAM 1045a3 is cleared ("game information clear process" S2303). Specifically, information related to the previous game is cleared. The information to be cleared includes, for example, information related to random numbers, information related to control of the reels L, M, and R, information related to winning, and information related to errors. Information related to winning includes information such as winning symbols, winning lines, and number of game balls to be won.

  After the game information clear process S2303, it waits while performing a predetermined process until a change start signal is input ("change wait process" S2304). Here, the fluctuation waiting process S2304 will be described in detail. FIG. 21 is a flowchart illustrating an example of the variation standby process.

  In the variable waiting process S2304, first, a game monitoring timer is set (“game monitoring timer setting process” S2401). Here, the setting of the game monitoring timer means that the value of the timer is reset and a new time measurement by the timer is started. The game monitoring timer is a timer for measuring a game interval, and when a predetermined time has elapsed without being played by the player, the image on the liquid crystal display device 42 is transferred to a predetermined image (demonstration image). Used to make

  After the game monitoring timer setting process S2401, it is determined whether or not a re-game has been won in the previous game. If a re-game has been won, the same number of games as the previous game bet is automatically set. The ball is automatically bet ("automatic betting process" S2402).

  After the automatic betting process S2402, it is confirmed whether an error has occurred in the selector 1400. If an error has occurred, the speaker 1106, 1204, the light emitting devices 1132, 1134L1, and various LED cover portions are covered. A throw error command for notifying the LED, the liquid crystal display device 1042, and the like of the error is set ("load error notifying process" S2403). For example, a case where an upstream passage detection signal or a downstream passage detection signal is received from the passage sensors 1415a, 1415b, and 1415c except during a game ball insertion period can be mentioned. The throw error command stored in the ring buffer is output to the sub control board 1047a in the command output process S2112 of the timer interrupt process executed after the storage. In the following, various commands stored in the ring buffer are output to the sub-control board 1047a in the command output process S2112 of the timer interrupt process executed after the storage as in the case of the input error command.

  After the insertion error notification process S2403, it is determined whether or not an error has occurred in the payout device 1033. If an error has occurred in the payout device 1033, a liquid crystal such as a speaker 1106, 1204 light emitting device 132, 134L1, etc. A payout error command for informing the display device 42 of an error is set ("payout error notification process" S2404). Specifically, whether or not a signal being paid out from the payout board 1037a is in an on state, and whether or not a count signal from the payout board 1037a based on count switch signals from various count sensors 1033h is in an on state. Is determined. If the result of this determination is that the payout signal is not in the on state (during the payout period) but one of the count signals is in the on state, error processing is executed and a payout error command is set. The As a result, the game cannot proceed and an error is notified. Note that the same payout error notification process is executed in a state waiting for some input from the player even during other processes, for example, in a reel stop waiting state during reel rotation.

  After the payout error notification process S2404, it is determined whether or not the return button 1308 has been operated. If the return button 1308 is being returned, input by the operation of another button or the like is prohibited ("return process" S2405).

  After the return process S2405, it is confirmed whether or not the 1 bet button 1114 or the max bet button 1304 is operated. If any of the bet buttons is operated, a predetermined number of game balls are bet (“ “Game Ball Bet Processing” S2406). Note that the number of inserted game balls is counted by the passage sensors 1415a, 1415b, and 1415c, and separately counted by the count sensors 1416a, 1416b, and 1416c.

  Here, the game ball betting process S2406 will be described in detail. FIG. 22 is a flowchart showing an example of the game ball betting process S2406. In the game ball betting process S2406, it is first determined whether or not the insertion has been completed (S2501). Specifically, in the normal gaming state or the like, if the bet number is “3” (the number of inserted balls is 15), it is determined that the insertion is completed, and during JAC, the bet number is “1” (the inserted ball). When the number is 5), it is determined that the insertion is completed. If the insertion has been completed, the game ball betting process S2406 ends. If the insertion has not been completed, it is determined whether or not a maximum bet signal has been received (S2502). When the maximum bet signal is received, the value of the total inserted number counter is set to “15” in the normal gaming state or the like, and to “5” during JAC or the like (“total inserted number counter setting process”). "S2503). On the other hand, if the maximum bet signal has not been received, it is determined whether or not a 1 bet signal has been received (S2504). When the 1-bet signal is received, the value of the total inserted number counter is set to “5” (“total inserted number counter setting process” S2505), and when it is not received, the game ball bet process S2406 is performed. Ends.

  When the value of the total thrown number counter is set in the total thrown number counter setting processes S2503 and S2505, the first to third article throwing retry flags are respectively set ("all throwing retry flag setting process" S2506). Initial setting is performed so that the insertion processing is performed in all of the three game ball insertion units 1410a to 1410c. After all throw retry flag setting processing S2506, it is determined whether or not any throw retry flag is set (S2507), and if all payout retry flags are not set, game ball betting processing is performed. S2406 ends. On the other hand, if the input retry flag is set for any item, it is determined whether or not the value of the total input number counter is “0” (S2508), and the value of the total input number counter is “0”. If there is, the game ball betting process S2406 ends.

  If the value of the total inserted number counter is not “0” in the determination process S2508, it is determined whether or not the all-item payout retry flag is set (S2509). In the determination process 2509, if the throw-in retry flag of any item is released, the payout of the game ball is delayed in any item as will be described later. The system waits for a time (“wait process” S2510), and then proceeds to the input number distribution process S2511. In this embodiment, the wait time in the wait process S2510 is 80 ms. This weight processing S2510 is provided in order to suppress the flapping of game balls when the flow of game balls to the discharge passages 1406a to 1406c is prohibited in the ball passages 1402a to 402c by the input flickers 1413a to 1413c. . Further, it is provided to accurately determine the transient response of the voltage in driving the closing solenoids 1414a to 1414c for operating the closing flickers 1413a to 1413c.

  In order to throw game balls as evenly as possible in the plurality of game ball throwing units 1410a to 1410c, the number of each game ball throwing unit thrown is distributed, and the planned number of throws corresponding to each game ball Is determined ("input number distribution process" S2511).

  After the throwing number distribution process S2511, it is determined whether or not the throwing timer interrupt execution flag is set (S2512). If the insertion timer interrupt execution flag is set, the maximum value “3” is set in the input item pointer (“input item pointer maximum value setting process” S2513). After the throwing-in pointer maximum value setting process S2513, the game is assigned to each of the game ball throwing units 1410a to 1410c by the throwing number sorting process S2511 and thrown in each game ball throwing unit 1410a to 1410c. The number of balls thrown is counted and a process for managing the end of the throw is executed ("insertion execution process" S2514). After the insertion execution process S2514, a process for managing counting of the number of game balls passing through the respective count sensors 1416a to 1416c is executed ("count sensor passing number counting process" S2515). After the count sensor passing number counting process S2515, it is determined whether or not the throwing line pointer is the minimum value “1” (S2516). If the input item pointer is not “1”, the value of the payout item pointer is decreased by “1” (“input item pointer subtraction process” S2517), and the process returns to the input execution process S1514. On the other hand, if the making line pointer is “1”, the driving of each making solenoid 1414a to 1414c is controlled based on each making solenoid operation flag (“all entry solenoid operation control process” S2518). Specifically, the dispensing solenoids 1414a to 1414c having the newly set closing solenoid operating flag are changed to the on state, and the closing solenoids 1414a to 1414c having the already set closing solenoid operating flag are maintained in the on state and are turned on. The closing solenoids 1414a to 1414c whose solenoid operation flag has been newly released are changed to the off state, and the closing solenoids 1414a to 1414c whose release solenoid operation flag has already been released are maintained in the off state.

  After the all-row solenoid operation control processing S2518, it is determined whether or not the value of the all-pass sensor counter is “0” (S2519). If the value of the all-pass sensor counter is “0”, the process returns to the determination process S2507. On the other hand, if the value of any of the passage sensor counters is not “0”, the input timer interrupt execution flag is canceled (“input timer interrupt execution flag release process” S2520), and the process returns to the determination process S2512. As described above, the game ball betting process S2406 is realized by the determination process S2501 to the insertion timer interrupt execution flag releasing process S2520.

  Returning to FIG. 21, after the game ball betting process S2406 is completed, it is determined whether or not the bet number is less than the minimum prescribed number (S2407). If the bet number is less than the minimum prescribed number, the insertion error notification process S2403 to the determination process S2407 are repeated. On the other hand, if the bet number is not less than the minimum prescribed number, it is determined whether or not a change start signal corresponding to the operation of the start lever 1124 has been received (S2408). If the variation start signal has not been received, the process from the error notification process S2403 to the determination process S2408 is repeated. On the other hand, when the variation start signal is received, the number of game balls counted by the passage sensors 1415a to 1415c in the game ball betting process S2406 is compared with the number of game balls counted by the count sensors 416a to 416c. If the number of game balls counted by the count sensors 1416a to 1416c is less than the number of game balls counted by the passage sensors 1415a to 1415c, an error process (number error process) is executed ("injected ball"). Number comparison process "S2409). As described above, through the processing steps (S2401 to S2409), the fluctuation waiting process S2304 is completed.

  After the change waiting process S2304, as shown in FIG. 20, the value of the random number counter latched by hardware when the start lever 1124 is operated is read and stored in the RAM 45a3 (“random number generation”). Processing "S2305). When the start lever 1124 is operated, the random number counter is latched by hardware so that the operation of the start lever 1124 and the acquisition of the random number value are synchronized in time. Note that although the value of the random number counter can be read by software, in this case, the time from the operation of the start lever 1124 to the acquisition of the random number value is more uneven than in the case of latching by hardware.

  After the random number generation process S2305, the winning combination corresponding to the random value acquired in the random number generation process S2305 is determined by referring to the random number table corresponding to the probability setting, the number of bets, and the gaming state, and according to the type of the winning combination Winning flags (for example, Big Bonus Winning Flag, Regular Bonus Winning Flag, Cherry Winning Flag, Bell Winning Flag, Watermelon Winning Flag, Replay Winning Flag) are set. A set value command representing a value is set ("internal lottery process" S2306). Winning roles include, for example, a big bonus role (hereinafter also referred to as “BB”), a regular bonus role (hereinafter also referred to as “RB”), and various small roles (in this embodiment, a cherry role, a bell role, and a watermelon role) , A re-playing role and a loser role. Note that a plurality of types of winning combinations may be selected in one game.

  After the internal lottery process S2306, based on the winning combination, the number of bets, and the gaming state, one manual stop control table used for controlling each of the cylinders L, M, R from the manual stop control table group held in the ROM 1045a2 is reference-controlled. The table is selected as a table, and the table number of the reference control table is stored in a predetermined area of the RAM 1045a3 ("rotation initialization process" S2307). When the winning combination is other than losing, slip control is performed in accordance with this reference control table to rotate the rotating cylinder extra within a predetermined range (5 symbols) in order to win the winning combination as much as possible. When the winning combination is lost, the same slip control is performed in order to prevent other winning combinations from winning. This reference control table is reselected from the manual stop control table group as necessary. In this embodiment, each of the spinning cylinder stop buttons 1126L, 1126M, and 1126R are arranged in a predetermined order (for example, “left spinning cylinder stop button 1126L → middle spinning cylinder stop button 1126M → right spinning cylinder stop button 1126R” and “left spinning cylinder stop button 1126L”). → right turn stop button 1126R → middle turn stop button 1126M ”), and in other operation orders, the reference control table is reselected from the manual stop control table group. The predetermined symbol pattern is stopped by another control method or by using them. Further, when the change of the symbol display is automatically stopped, it is stopped with a predetermined symbol pattern by referring to the automatic stop control table held in the ROM 1045a2.

  After the rotation initialization process S2307, a symbol variation standby process S2308 is executed. In the symbol variation standby process S2308, first, it is determined whether or not the measurement time by the symbol variation monitoring timer is equal to or longer than a predetermined time (for example, 4.1 seconds). Here, the “symbol fluctuation monitoring timer” is a timer that measures the elapsed time from the time of the last symbol display fluctuation start. If the measurement time of the symbol fluctuation monitoring timer is less than a predetermined specified time, a variable waiting command (internal state command of the internal state command) indicating that the specified time has elapsed (hereinafter referred to as “variable waiting state”). Is stored in the ring buffer. Note that the player is informed of the variable standby state by a variable standby state display device (not shown). After that, until the measurement time of the symbol fluctuation monitoring timer becomes equal to or longer than the predetermined specified time, whether or not the measurement time by the symbol fluctuation monitoring timer is equal to or longer than the predetermined specified time while the change waiting state is notified. Is repeated. On the other hand, when the measurement time of the symbol fluctuation monitoring timer is equal to or longer than the predetermined specified time, the symbol fluctuation monitoring timer is reset and started, the notification of the standby state for the specified time is stopped, and the predetermined specified time has elapsed. A specified time elapse command (a kind of internal state command) indicating this and a bet number command to be output to the external concentration terminal board are stored in the ring buffer. Thereafter, information related to drive control of each of the stepping motors 1043L4, 1043M4, and 1043R4 of the rotating drum unit 1043 in a predetermined area of the RAM 1045a3 is initialized for starting rotation. For example, the value of the wait timer is set to “0”, and the value of the acceleration counter is set to “26”. The actual driving of the stepping motors 1043L4, 1043M4, and 1043R4 is controlled by various stepping motor control processes S2105 to S2107 (see FIG. 16) of the timer interrupt process.

  After the symbol variation standby process S2308, a rotation control process S2309 for controlling the rotation of each of the spinning cylinders L, M, and R in the spinning cylinder unit 1043 is executed. Here, the rotation control process S2309 will be described in detail. FIG. 23 is a flowchart illustrating an example of the rotation control process.

  In the rotation control process S2309, information about rotation of each of the spinning cylinders L, M, R in a predetermined area of the RAM 45a3 is initialized, and an all-rotating cylinder rotation command indicating that all of the spinning cylinders L, M, R are rotating. (A type of spinning rotation information command) and a symbol variation state command (a type of internal state command) indicating a symbol display variation state in the spinning unit 1043 are stored in the ring buffer ("rotation start process" S2601). ). After the rotation start process S2601, the process waits until a predetermined stop standby time elapses ("design stop standby process" S2602). The “predetermined stop standby time” in the symbol stop standby process S2602 is substantially the same time as the average time required from the start of rotation of each of the cylinders L, M, and R to steady rotation at a constant speed. After the symbol stop standby process S2602, it is determined whether or not the rotations of all the spinning cylinders L, M, and R are steady rotations (S2603). Specifically, whether or not these rotations are steady rotations is determined by whether or not a detection signal is received from the rotating cylinder position detection sensor 1043R7 corresponding to the rotating cylinder that has started rotating last. If the detection signal is received, it is determined that the rotations are steady rotations. If the detection signal is not received, it is determined that the rotation of any of the rotating cylinders is not steady rotations. . If these rotations are not steady rotations, the determination process S2603 is repeatedly executed. In this embodiment, all the spinning cylinders L, M, R start to rotate simultaneously.

  If it is determined in the determination process S2603 that all the rotations of the cylinders are steady rotations, an automatic stop timer for measuring the fluctuation time of the symbol display until the automatic stop is set ("automatic stop timer setting process" S2604). ). After the automatic stop timer setting process S2604, it is determined whether the time measured by the automatic stop timer exceeds the specified rotation time (S2605). If the measurement time by the automatic stop timer does not exceed the specified rotation time, the following process for manually stopping the symbol display fluctuation is executed.

  It is determined whether or not a left stop signal corresponding to the operation of the left cylinder stop button 1126L is received (S2606). If the left stop signal has not been received, it is determined whether or not an intermediate stop signal corresponding to the operation of the middle-cylinder stop button 1126M has been received (S2607). If the middle stop signal has not been received, it is determined whether or not a right stop signal corresponding to the operation of the right-turn cylinder stop button has been received (S2608). If the right stop signal has not been received, that is, if any of the left stop signal, the right stop signal, and the right stop signal has not been received, the determination process S2606 is executed.

  If it is determined in the determination process S2606 that a left stop signal has been received, it is determined whether a left stop flag is set (S2609). The “left stop flag” is a flag for identifying whether the left cylinder L is rotating or stopped, and is canceled in the rotation initialization process S2307. When the left stop flag is set, it indicates that the left cylinder L has already stopped, and when the left stop flag is released, it indicates that the left cylinder L is rotating. When the left stop flag is set, the determination process S2606 is executed. On the other hand, when the left stop flag is released, the left-turn cylinder stop process S2610 is executed. In the left turning cylinder stop process S2610, first, the left stepping motor 1043L4 that rotates the left turning cylinder L is stopped with reference to the reference control table. After the left stepping motor 1043L4 stops, a left stop flag is set, the number of stop rotations is incremented, and a left rotation stop command (a type of rotation rotation information command) indicating that the left rotation L is stopped; A left swirl symbol command (a kind of stop symbol command) representing a stop symbol of the left swirl L is stored in the ring buffer. The “number of stopped spinning cylinders” represents the number of stopped spinning cylinders, and is reset to “0” in the rotation start process S2601.

  Here, the left turn cylinder stop processing S2610 will be described in detail. In the left-turning cylinder stop processing S2610, first, with reference to the current symbol number held in the RAM 1045a3, the stop reference symbol number is set to a value obtained by adding 1 to the current symbol number. After the stop reference symbol number is set, if the left cylinder L is the second cylinder that has been stopped, the currently selected reference control table is changed to another control table as necessary. . If the left turn cylinder L is not the second stop, the control table is not changed. Thereafter, referring to the reference control table, a slip amount corresponding to the stop reference symbol number is extracted, and a value obtained by adding the slip amount to the stop symbol number is set as the stop symbol number. When the stop symbol number exceeds 20 (maximum symbol number), the stop symbol number is changed to a value obtained by subtracting 21 from the current value. After the stop symbol number is set, the stop interval timer is set. The stop interval timer is a timer that measures a period during which a stop instruction for the next spinning cylinder is not accepted. Note that the value of the stop interval timer is set to a predetermined time exceeding the maximum time in consideration of the time required for the rotation corresponding to the slip amount and the subsequent stop of the spinning cylinder. Thereafter, when the measurement time of the stop interval timer exceeds a predetermined time, the left stop flag is set, and the left cylinder stop process S2610 ends.

  After the left rotation stopping process S2610, it is determined whether or not the number of stop rotations is 3 (S2611). If the number of stop cylinders is not 3, that is, if at least one of the cylinders is rotating, it is determined whether or not the reference control table needs to be changed (S2612). When it is necessary to change the reference control table when stopping the unstopped cylinder, the reference control table is changed to another manual stop control table selected from the manual stop control table group ("control table change process"). S2613). In the control table change process S2613, the stop position of the already-rotated cylinder of the middle and right cylinders M and R is referred to together with the stop position of the left cylinder L. As a case where it is necessary to change the reference control table, for example, there is a case where a combination other than the winning combination wins.

  If it is determined in the determination process S2607 that an intermediate stop signal has been received, it is determined whether or not an intermediate stop flag is set (S2614). As in the case of the left stop flag, the “intermediate stop flag” is a flag for identifying whether the middle drum M is rotating or stopped, and is canceled in the rotation start process S2601. If the middle stop flag is set, determination processing S2606 is executed. On the other hand, when the middle stop flag is released, it is determined whether or not the number of stop rotations is 0 (S2615). If the number of stop cylinders is not 0, the middle cylinder stop process S2617 is executed. On the other hand, when the number of stop rotations is 0, a predetermined manual stop control table in the manual stop control table group is reset as a reference control table (“control table resetting process” S2616), and the control table is reset. After the process S2616, a mid-cylinder stop process S2617 is executed. Note that the middle cylinder stop process S2617 is the same process as the left cylinder stop process S2610. In the middle cylinder stopping process S2617, first, the middle stepping motor 1043M4 that rotates the middle cylinder M is stopped with reference to the reference control table. The control for stopping the middle stepping motor is substantially the same as the control for stopping the left stepping motor 43L4. After the middle stepping motor 1043M4 is stopped, an intermediate stop flag is set, the number of stop rotations is incremented, and a middle rotation stop command (a kind of rotation rotation information command) indicating that the middle rotation cylinder M is stopped. ) And a middle-rotor symbol command (a kind of stop symbol command) representing a stop symbol of the middle drum M is stored in the ring buffer.

  After the middle cylinder stop process S2617, it is determined whether or not the number of stop cylinders is 3 (S2618). If the number of stop cylinders is not 3, it is determined whether or not the reference control table needs to be changed when stopping the unrotated cylinder (S2619). When the reference control table needs to be changed, the reference control table is changed to another manual stop control table selected from the manual stop control table group ("control table change process" S2620). In the control table changing process S2620, the stop symbol numbers of all the rotating cylinders that have already stopped among the left rotating cylinder L and the right rotating cylinder R are referred to together with the stop position of the middle rotating cylinder M.

  If it is determined in the determination process S2608 that a right stop signal has been received, it is determined whether a right stop flag is set (S2621). As in the case of the left stop flag and the middle stop flag, the “right stop flag” is a flag for identifying whether the right cylinder R is rotating or stopped, and is canceled in the rotation start process S2601. If the right stop flag is set, determination processing S2606 is executed. On the other hand, if the right stop flag is released, it is determined whether or not the number of stop rotations is 0 (S2622). When the number of stop rotations is not 0, the right rotation stop process S2624 is executed. On the other hand, when the number of stop rotations is 0, a predetermined manual stop control table in the manual stop control table group is reset as the reference control table (“control table resetting process” S2623), and the control table is reset. After the process S2623, a right cylinder stop process S2624 is executed. Note that the right crotch stop processing S2617 is the same processing as the left crotch stop processing S2610. In the right cylinder stop process S2617, first, the right stepping motor 1043R4 that rotates the right cylinder R is stopped with reference to the reference stop control table. The control for stopping the right stepping motor is substantially the same as the control for stopping the left stepping motor 1043L4. After the stop of the right stepping motor 1043R4, a right stop flag is set, the number of stop rotations is incremented, and a right rotation stop command (a type of rotation rotation information command) indicating that the right rotation R is stopped ) And a right swirl symbol command (a kind of stop symbol command) representing a stop symbol of the right swirl are stored in the ring buffer.

  After the right turn stopping process S2624, it is determined whether or not the number of stop turns is 3 (S2625). If the number of stop cylinders is not 3, it is determined whether or not the reference control table needs to be changed when stopping the unrotated cylinder (S2626). When the reference control table needs to be changed, the reference control table is changed to another manual stop control table selected from the manual stop control table group ("control table change process" S2627). In the control table changing process S2627, the stop symbol numbers of all the rotating cylinders that have already stopped among the left rotating cylinder L and the middle rotating cylinder M are referred to together with the stop position of the right rotating cylinder R.

  In the determination process S2605, when the time measured by the automatic stop timer exceeds the specified rotation time, the rotation of all the cylinders L, M, and R that are currently rotating is stopped ("automatic stop process" S2628). After the automatic stop process S2628, and when it is determined in the determination process S2611, the determination process S2618, and the determination process S2625 that the number of stop rotations is “3”, the automatic stop timer is canceled.

  Here, the automatic stop process S2628 will be described in detail. In the automatic stop process S2628, first, one table is set as a reference control table from the automatic stop control table group held in the ROM 1045a2 with reference to the stop symbol number (stop position) of the rotating cylinder that has already stopped. . Thereafter, it is determined whether or not the left stop flag is set. If the left stop flag is not set, the rotation of the left cylinder L is stopped. Next, it is determined whether or not the intermediate stop flag is set. If the intermediate stop flag is not set, the rotation of the intermediate drum M is stopped. Thereafter, it is determined whether or not the right stop flag is set. If the middle stop flag is not set, the rotation of the middle cylinder R is stopped.

  After the rotation control process S2309, as shown in FIG. 20, a winning confirmation process S2310 is executed. In the winning confirmation process S2310, first, the pattern pattern for each activated line is confirmed, and if any winning combination other than the winning combination has been won, an error process for notifying the occurrence of a winning error is executed. The On the other hand, if only the winning combination is winning, a winning flag corresponding to all winning winning combinations (for example, big bonus winning flag, regular bonus winning flag, cherry winning flag, bell winning flag, watermelon winning flag, A replay winning flag) is set. Further, the number of acquired game balls corresponding to each winning combination won is added within a range not exceeding the maximum number of acquired game balls, so that the number of acquired game balls is finally determined. Further, in the winning confirmation processing S2310, a winning combination command including information on the type of winning combination, a winning line command including information on the type of winning line, and a winning combination error command including information on winning error are stored in the ring buffer. .

  After the winning confirmation process S2310, a payout command including information on the number of acquired game balls is set ("acquired ball payout process" S2311). After the acquired game ball payout process S2311, a re-game process S2312 is performed. In the re-game process S2312, various processes such as setting the internal state to a re-game are performed when the re-game win flag is set in the win confirmation process S2310. Further, a re-game command (a kind of internal state command) indicating that the next game is a re-game is stored in the ring buffer.

  After the re-game process S2312, an accessory operating process S2313 is performed. In the in-community-acting process S2313, processing during the actuating of an accessory such as a big bonus (BB) combination and a regular bonus (RB) combination is performed. When the internal state is the big bonus game state, control during the small role game, transition control from the small role game to the JAC game, control during the JAC game, transition control from the JAC game to the small role game, and the big bonus Game state end control and the like are performed. The end determination of the big bonus game state is determined by whether or not the total number of game balls acquired during that state is greater than or equal to a predetermined number. When the total number of acquisitions is equal to or greater than the predetermined number of acquisitions, a big bonus end process is performed. On the other hand, when the total number of acquisitions is less than the predetermined number of acquisitions, the big bonus end process is skipped. On the other hand, when the internal state is a regular bonus, control during the JAC game, end control of the regular bonus game state, and the like are performed. The termination condition for the regular bonus is also determined by whether or not the total number of acquisitions is equal to or greater than the predetermined number of acquisitions.

  After the accessory operating process S2313, an accessory operating determination process S2314 is performed. In the combination act determination process S2314, a winning flag for the big bonus combination indicating that the big bonus combination is won is set, and a big bonus winning flag indicating that the big bonus combination is won is set. If so, a process for starting the big bonus is executed ("BB start process"). In addition, when the regular bonus combination winning flag indicating that the regular bonus combination is won is set and the regular bonus winning flag indicating that the regular bonus combination is won is set, the regular bonus combination is set. Is executed ("RB start process").

  After the accessory operation determination process S2314, a game progress display process S2315 is executed. In the game progress display processing S2315, when the internal state is a big bonus game state or a regular bonus game state, data for displaying the number of remaining JAC games, the total number of acquired game balls in one big bonus, and the like. Is set. In addition, after the end of the big bonus or regular bonus, the internal state is changed to the specific gaming state in order to shift to a specific gaming state such as a replay time (“RT”) in which the winning probability of replaying is higher than the normal gaming state. The specific game state command (a kind of internal state command) indicating the specific game state is set and stored in the ring buffer.

  A control process executed by the payout control board 1037a will be described. The control process of the payout control board 1037a is roughly divided into a main process that is activated in response to power recovery by restarting the supply of external power or turning on the power switch 1038a, and an interrupt process that interrupts the main process. The For convenience of explanation, after describing the interrupt process, the main process will be described. The interrupt process includes a command interrupt process for interrupting in response to reception of various commands from the main control board 1045a and a timer interrupt process that is periodically and repeatedly executed (2 ms in this embodiment). For convenience of explanation, the interrupt process will be described first, followed by the main process.

  First, command interrupt processing will be described. FIG. 24 is a flowchart illustrating an example of command interruption processing of the payout control board 1037a. The command interruption process is executed when the payout control board 1037a receives a command from the main control board 1045a. As shown in FIG. 24, when the command interrupt process is executed, first, the received command is stored in the data buffer for reception ("received command storage process" S3001). After the command reception process S3001, a command reception flag is set ("command reception flag setting process" S3002). The external interrupt process ends when the command reception flag setting process S3002 ends.

  Next, timer interrupt processing will be described. FIG. 25 is a flowchart showing an example of timer interrupt processing of the payout control board 1037a. As shown in FIG. 25, in the timer interrupt process, first, it is determined whether or not a command reception flag is set (S3101). When the command reception flag is set, the command stored in the data buffer for reception is read (“command reading process” S3102). After the command reading process S3102, the command reception flag is canceled ("command reception flag cancellation process" S3103). After the command reception flag release processing S3103, it is determined whether or not the read command is a payout command (S3104). If it is a payout command, the number of prize balls (number of payouts) corresponding to the type of payout command is set in the prize ball number counter (“prize ball number counter setting process” S3105). On the other hand, when the read command is not a payout command, the winning ball number counter setting process S3105 is skipped. If it is determined in the determination process S3101 that the command reception flag is not set, the command reading process S3102 to the prize ball number counter setting process S3105 are skipped.

  Next, the state of the detection signal from the overflow detection switch (not shown) is confirmed, and setting control of the lower pan full state is performed based on the reception state ("lower pan full state setting process" S3106). . Specifically, when the overflow detection switch is continuously detected for 200 ms, “bottom pan is full”, the lower pan full state is set, and in other cases, the lower pan is full. Is released.

  After the lower plate full state setting process S3106, the reception state of the game ball detection signal from each ball break detection device 1035b is confirmed, and setting control of the ball presence state is performed based on the reception state (“ball presence state”). Setting process "S3107). Specifically, setting control for the presence of a sphere is performed as follows. First, it is determined whether or not all the game ball detection signals are in the ON state, that is, it is determined whether or not a predetermined number or more of game balls are stored in all of the ball paths 1033d and 1035a. When all the game ball detection signals are in the on state, it is confirmed whether or not the state continues for 2000 ms. When the on-state of the game ball detection signal has passed 2000 ms, there are more than a predetermined number (20 in this embodiment) of game balls in all the ball passages 1035a. When the ball presence state setting process S4007 ends and the on-state of the game ball detection signal has not elapsed 2000 ms, the ball presence state setting process S3106 ends as it is. On the other hand, when at least one of the game ball detection signals is in the off state, it is determined whether or not the state continues for 200 ms. If the state has passed for 200 ms, the ball presence flag is canceled. Then, the sphere presence state setting process S3107 ends, and if the state does not continue for 200 ms, the sphere presence state setting process S3107 ends as it is.

  After the ball presence state setting processing S3107, when the state in the lower pan full state setting processing S3106 or the ball presence state setting processing S3107 is a state to be notified, the state is notified ("state notification process" S3108). . Specifically, in the case of “full of lower tray ball”, the player is informed by the sound from the speakers 1106 and 1204, or the player is informed by the image by the liquid crystal display device 1042. . Further, when the game ball is not stored in the game ball tank 1032 (when the flag with a ball is released), the player is similarly notified of the fact.

  After the status notification process S3108, it is determined whether or not the prize ball payout is disabled (S3109). The prize ball payout disabled state is a case where a payout of a ball is currently being executed. If the prize ball payout is not disabled, it is determined whether or not the value of the prize ball number counter is “0” (S3110). When the value of the prize ball number counter is “0”, there is no game ball to be paid out based on the payout command, so the process proceeds to S3112. If the value of the prize ball number counter is not “0”, Since there is a game ball to be paid out based on the payout command, “1” is set in the payout state counter (“payout state counter setting process” S3111). If it is determined in the determination process S3109 that the prize ball cannot be paid out, or if the value of the prize ball number counter is “0” in the determination process S3110, the process proceeds to the next process S3112.

  Next, it is determined whether or not the rental ball payout state is disabled (S3112). Note that the rental ball payout disabled state is a case where the payout of the winning ball is currently being executed. If it is not in the lend-out status, it is determined whether or not a lend-out request signal is received from the card unit (S3113). If the rental ball payout request signal has been received, “2” is set in the payout state counter in order to pay out the winning ball (“payout state counter setting process” S3114). On the other hand, when the lending payout request signal has not been received, the payout state counter setting process S3114 is skipped. If it is determined in S3112 that the rental ball payout is not possible, the determination process S3113 and the payout state counter setting process S3114 are skipped.

  Next, a payout timer interrupt execution flag is set ("payout timer interrupt execution flag setting process" S3115). After the payout timer interrupt execution flag setting process S3115,

  The main process in the payout control board 1037a will be described. FIG. 26 is a flowchart showing an example of the main process of the payout control board. As shown in FIG. 26, in the main process, first, various settings are made for a register group around the CPU, an I / O device, and the like ("initial setting process" S3201). After the initial setting process S3201, access to the RAM 1037a3 is permitted ("RAM access permission process" S3202), and an external interrupt vector is set ("external interrupt vector setting process" S3203). After the external interrupt vector setting process S3203, all areas of the RAM 1037a3 are cleared to “0” (S3204), and then an initial value is set in the RAM 1037a3 (“RAM initial setting process” S4105), and other peripheral devices of the CPU 37a1. Initial setting is performed ("CPU peripheral device initial setting process" S3206). After the CPU peripheral device initial setting process S3206, interrupt permission is set (S3207), and the game ball payout process S3208 is repeatedly executed. In a normal game, in response to receiving a payout command from the main control board 1045a, pay out game balls with the number of winning balls based on the type of payout command, and pay out 25 game balls when a lending payout request is made. It is processing to issue.

  Here, the game ball payout process S3208 will be described in detail. FIG. 27 is a flowchart showing an example of the game ball payout process. As shown in FIG. 27, in the game ball payout process S3208, it is first determined whether or not the value of the payout state counter is “0” (S3301). When the payout state counter is “0”, that is, when no payout command is received, it is determined whether or not reception of a count switch signal from the count sensor 33h is detected (S3302). When reception of the count switch signal is detected, processing for outputting the count signal to the main control board 1045a is performed (“count signal output processing” S3303). On the other hand, when the reception of the count switch signal is not detected, the count signal output process S3303 is skipped. If it is determined in the determination process S3301 that the value of the payout state counter is other than “0”, the determination process S3302 and the count signal output process S3303 are skipped.

  Next, it is determined whether or not a sphere presence flag is set (S3304). When the ball presence flag is not set, the game ball payout process S3208 is not performed because the game balls cannot be paid out because a predetermined number or more of the game balls are not stored in the ball passage 1035a of the case rail 1035. finish. On the other hand, when the ball presence flag is set, the process proceeds to S3305 and subsequent steps in order to pay out the game ball.

  If it is determined in the determination process S3304 that the ball presence flag is set, the value of the payout state counter is confirmed (S3305, S3307), and if the value is neither “1” nor “2” Since it is not the situation to pay out the game ball, the game ball payout process S3208 ends. When the value of the payout state counter is “1”, the game ball is paid out based on the payout command, so the value of the prize ball number counter is set in the total payout number counter (“total payout number”). Counter setting process "S3306). On the other hand, when the value of the payout state counter is “2”, “25” is set as the value of the total payout number counter (“total payout number counter setting process” S3308). The reason why “25” is set as the value of the total payout number counter is that, in this embodiment, 25 game balls are paid out each time a lending payout request signal is received.

  When the value of the total payout number counter is set in the total payout number counter setting processing S3306, S3308, the first to fourth payout retry flags are set ("retry flag setting processing for all items" S3309). Initial setting is performed so that the payout process is performed for all four ball passages 1033d. After the all-item payout retry flag setting process S3309, output of a payout signal to the main control board 1045a is started ("payout signal output start process" S3310).

  After the payout signal output start process S3310, it is determined whether any payout retry flag is set (S3311). If all the payout retry flags are not set, error processing is executed to It is notified that the payout has become impossible in a state where the ball has not been paid out ("error processing" S3312). The error process S3312 is an infinite loop, and the error can be eliminated by resetting the ball-type spinning gaming machine 10. On the other hand, if any one of the payout retry flags is set, it is determined whether or not the value of the total payout number counter is “0” (S 3313), and if the value of the total payout number counter is “0”. Then, it is determined whether or not the value of the payout state counter is “2” (S3314). If the value of the payout state counter is “2”, a lending end signal is output to the CR unit (“lending end signal output process” S3315). Since the payout is not based on the payout request signal, the loan end signal output process S3315 is skipped. Next, the value of the payout state counter is set to “0” (“payout state counter initialization process” S3316), the output of the payout signal is stopped (“payout signal output stop process” S3328), and the game ball The payout process S3308 ends. When the value of the payout state counter is set to “0”, the winning ball payout is prohibited and the lending payout is prohibited.

  Before the determination process S3313, it is confirmed whether or not the payout retry flag of any of the articles is released. If the payout retry flag is not set even in one of the articles, an abnormality such as a ball clogging occurs. Therefore, error processing may be performed. That is, if even one of the ball paths 1033d of the payout device 1033 is clogged, even if 80 or more game balls are stored in the ball path 1035a of the case rail 1035, the game balls cannot be paid out reliably. In some cases, the game ball can be paid out reliably by urging the user to cancel the abnormality by executing error processing.

  If the value of the total payout number counter is not “0” in the determination process S3313, it is determined whether or not the payout retry flag for all items is set (S3317). If one of the payout retry flags is canceled in the determination process 3317, the payout of the game ball has been delayed in any of the articles as will be described later, so that it waits for a predetermined time before redistributing the game balls. ("Wait process" S3318), and thereafter, the process proceeds to a payout number distribution process S3319. In this embodiment, the wait time in the wait process S4218 is 80 ms. This wait process S4218 is provided to suppress fluttering of the game ball on the upstream side of the payout passage 1033e when the ball passage 1033d of the game ball is closed by the payout flicker 1033b. Further, it is provided to accurately determine the transient response of the voltage in driving the dispensing solenoid 1033c that operates the dispensing flicker 1033b. On the other hand, when the all-item payout retry flag is set, the process proceeds to the payout number distribution process S3319 without performing the wait process S3318.

  In order to pay out game balls evenly in the four ball passages 1033d from which game balls are paid out, the number of payouts to be paid out by each of the ball passages is distributed (“payout number distribution process” S4219). ). After the payout number distribution process S3319, it is determined whether or not a payout timer interrupt execution flag is set (S3320). If the payout timer interrupt execution flag is set, the maximum value “4” is set in the payout item pointer (“payout item pointer maximum value setting process” S3321). After the payout item pointer maximum value setting process S3321, the number of game balls that are distributed to each ball path by the payout number distribution process S3319 and started to be paid out in each ball path 33d are counted and the payout is performed. Is executed (“payout execution process” S3322). After the payout execution process S3322, it is determined whether or not the payout item pointer is the minimum value “1” (S3323). If the payout item pointer is not “1”, the value of the payout item pointer is decreased by “1” (“payout item pointer subtraction process” S3324), and the process returns to the payout execution process S4222. On the other hand, if the payout line pointer is “1”, each payout solenoid 1033c is driven based on each payout solenoid operation flag (“all line payout solenoid operation control process” S3325). Specifically, in each article, when the payout solenoid operation flag is newly set, the payout solenoid 1033c is changed to an on state, and when the payout solenoid operation flag is already set, the payout solenoid 1033c is turned on. When the state is maintained and the payout solenoid operation flag is newly released, the payout solenoid 1033c is changed to an off state, and when the payout solenoid operation flag is already released, the off state of the payout solenoid 1033c is maintained. The

  After all payout solenoid operation control processing S3325 for all items, it is determined whether or not the value of the payout game ball counter for all payouts is “0” (S3326). If all the payout game ball counter values are “0”, the process returns to the determination process S3311. On the other hand, if the value of any payout game ball counter is not “0”, the payout timer interrupt execution flag is canceled (“payout timer interrupt execution flag release process” S3328), and the process returns to the determination process S3320. As described above, the game ball payout process S3208 is realized by the determination process S3301 to the payout signal transmission stop process S3328.

  A control process executed by the sub control board 1047a will be described. The control process of the sub control board 1047a is roughly divided into a main process that is activated when the external power is restored from a power failure or a power is restored by turning on the power, and an interrupt process that interrupts the main process. For convenience of explanation, after describing the interrupt process, the main process will be described. As interrupt processing in the CPU, there are regular timer interrupt processing and regular command interrupt processing.

  The timer interrupt process will be described. FIG. 28 is a flowchart illustrating an example of timer interrupt processing in the sub-control board 1047a.

  The timer interrupt process is executed with a period of approximately 1 ms. In the timer interrupt process, first, an interrupt flag is read (“interrupt flag read process” S4001). After the interrupt flag reading process S4001, it is determined whether or not the interrupt flag is valid (S4002). Specifically, it is confirmed that it is a timer interrupt among various interrupts to the CPU. If the interrupt flag is valid, the interrupt timer counter is incremented and the interrupt timer counter is updated ("interrupt timer counter update process" S4003). After the interrupt timer counter update process S4003, the interrupt flag related to the timer interrupt is canceled ("interrupt flag release process" S4004). As a result, the next timer interrupt process for the CPU can be executed. If it is determined in the determination process S4002 that the interrupt flag is not valid, the interrupt timer counter update process S4003 and the interrupt flag release process S4004 are skipped because they are other interrupt processes.

  The command interrupt process will be described in detail. FIG. 29 is a flowchart illustrating an example of command interrupt processing in the sub-control board 1047a. The command interrupt process is executed in response to the transmission of a command from the main control board 1045a. Since the command transmission in the main control board 45a is performed with a period of approximately 1.49 ms, this processing is performed with a period of approximately 1.49 ms.

  In the command interrupt process, first, it is determined whether or not the strobe signal from the main control board 45a is normal (S4101). If the strobe signal is normal, command data is acquired ("command data acquisition process" S4102). After the command data acquisition process S4102, it is determined whether or not the content is normal (S4103). When the command data is normal, the command is received (“command reception process” S4104), and after the command reception process S4104, the retry counter value is changed to a predetermined retry maximum value (“retry counter maximum value setting”). Process "S4105).

  If it is determined in step S4101 that the strobe signal is not normal, the retry counter value is changed to a predetermined maximum retry value (S4106). If it is determined in the determination process S4103 that the command data is not normal, the retry counter value is changed ("retry counter update process" S4107). In this change, the retry counter value is increased by one. After the process of changing the retry counter value (S4105, S4106, S4107), it is determined whether the retry counter value is the maximum value (S4108). When the retry counter value is the maximum value, the interrupt flag is read (“interrupt flag read process” S4109). After the interrupt flag reading process S4109, the value of the retry counter is cleared to the initial value “0” (“retry counter clear process” S4110). After the retry counter clear process S4110, the interrupt flag is released ("interrupt flag release process" S4111). By releasing the interrupt flag, the next command interrupt process can be executed.

  When the retry counter value is not the maximum value, that is, when the strobe signal is normal but the command data is not normal, the interrupt flag read process S4109, the retry counter clear process S4110, and the interrupt flag release process S4111 are skipped. The acquisition of command data at a predetermined timing is repeated until the retry counter value reaches a predetermined maximum retry value.

  The main process executed by the sub control board 1047a will be described in detail. FIG. 30 is a flowchart illustrating an example of the main process of the sub control board.

  In the main processing, first, in response to the supply of internal power from the power supply control board 1038 ′, initialization of the sub control board 1047a itself and initialization of peripheral devices such as the liquid crystal display device 1042 connected to the sub control board 1047a are performed. Is performed ("initialization process" S4201). After the initialization process S4201, it is determined whether or not the system state is a voltage drop state (S4202). Here, the system state includes a voltage drop state indicating that the supply voltage is equal to or lower than a predetermined voltage, and an initialization indicating that the sub-control board 1047a and the peripheral device connected to the sub-control board 1047a are being initialized. It implies a state and a normal state indicating that the supply voltage is a predetermined voltage and normal game can be performed. Note that the initialization state is selected during the initialization process S4201.

  When it is determined in the determination process S4202 that the system state is a voltage drop state, a backup process S4210 described later is executed. On the other hand, if the system state is not a voltage drop state, it is determined whether or not the value of the interrupt timer counter has changed (S4203). When the value of the interrupt timer counter is changed, the interrupt timer counter is updated (“interrupt timer counter update process” S4204). In the interrupt timer counter update process S4204, the value of the interrupt timer counter is decreased by 1. After the interrupt timer counter update process S4204, a periodic timer process S4205 described later is performed. After the cycle timer process S4205, it is determined whether or not the system state is a voltage drop state (S4206). If the system state is not a voltage drop state, it is determined whether any command is received from the main control board 1045a (S4207). If a command has been received, a received command confirmation process S4208 described later is performed. On the other hand, if a command has not been received, the received command confirmation process S4208 is skipped. After the received command confirmation process S4208, the base value of the random number that determines the details of the effect is updated ("random number base value update process" S4209). After the random number base value update process S4209, the process proceeds to a determination process S4202. When the system state is not a voltage drop state, the above-described processes (S4202 to S4209) are repeatedly executed in sequence.

  If it is determined in the determination processing S4202 and determination processing S4206 that the system state is a voltage drop state, register data and stack data are stored in the external RAM ("backup processing" S4210). After the backup process S4210, it is determined whether or not the system state is a voltage drop state (S4211). If the system state is a voltage drop state, the determination process S4211 is repeatedly executed. On the other hand, if the voltage drop state is not established, the system waits for a predetermined time (30 ms in this embodiment) to confirm that the cancellation of the voltage drop state is not a malfunction due to noise or the like (“wait process” S4212). After the wait process S4212, it is determined again whether or not the system state is a voltage drop state (S4213). If the system state is a voltage drop state, the process returns to the determination process S4211. On the other hand, if the system state is not a voltage drop state, it is determined that the supply of internal power has been resumed normally, and a process for starting the main process is performed ("start process" S4214). After the startup process S4214, the process returns to the initialization process S4201, and the main process is resumed.

  The periodic timer process S4205 in the main process of the sub control board 1047a will be described in detail. FIG. 31 is a flowchart illustrating an example of the periodic timer process. By executing the timer interrupt process substantially every 1 ms, the periodic timer process S4205 is also executed substantially every 1 ms. In the cycle timer process 4205, as shown in FIG. 31, first, a startup command confirmation process S4301 is executed. In the startup command confirmation process S4301, it is confirmed whether any command is received from the main control board 1045a within 2 seconds after the execution of the startup process S4214. When no command is received from the main control board 45a, it is determined that the main control board 1045a has not been normally activated, and processing for notifying the occurrence of an error is performed. On the other hand, if any command is received from the main control board 1045a, this process is terminated and the process proceeds to the device control process S4302.

  In the device control process S4302, the liquid crystal display device 1042, the speakers 1106 and 1204, and the various effect LED cover units 1104 are responded to the various commands confirmed to be received in the received command confirmation process S4208 (see FIG. 30) described below. Drive control of a light emitting device (not shown) covered with 1108 and 1110, various light emitting devices 1132, 1134L1, and the like is performed.

  In the system state change process S4303, it is determined whether or not there is a change in the system state. Depending on the determination result, the voltage drop flag indicating the voltage drop state and the initialization flag indicating the initialization state are set or canceled. . If there is a change in the system state, processing corresponding to the change is executed. When the voltage drop flag and the initialization flag are canceled, the system state is regarded as a normal state, and this process ends. After the system state changing process S4303, a voltage monitoring process S4304 is executed.

  In the voltage monitoring process S4304, it is determined whether or not the voltage of the internal power supplied from the power supply board 1038 ′ is equal to or lower than a predetermined voltage. If the internal voltage is equal to or lower than the predetermined voltage, the voltage drop flag is canceled. If the voltage drop flag is set, the voltage drop flag is set. On the other hand, if the internal voltage is not lower than the predetermined voltage, the voltage drop flag is canceled if the voltage drop flag is set. After the voltage monitoring process S4304, the value of the cycle timer counter is added to the value of the long cycle timer counter, and the long cycle timer counter is updated ("long cycle timer counter addition process" S4305). After the long cycle timer counter update process S4305, it is determined whether or not the value of the long cycle timer counter is 10 or more (S4306). By the determination process S4305, the following processes (S4307 to S4312) are executed approximately every 10 updates of the periodic timer counter. Since the periodic timer counter is updated approximately every 1 ms, the following processing is executed approximately every 10 ms.

  If it is determined in the determination process 2402 that the value of the long-period timer counter is less than 10, this process ends. On the other hand, when the value of the long cycle timer counter is 10 or more, the value of the long cycle timer counter is decreased by 10 and the value of the long cycle timer counter is updated ("long cycle timer counter subtraction process" S4307). . After the long period timer counter subtraction process S4307, data of a desired light emission pattern from a light emission data table including a plurality of light emission patterns for various light emitting devices (light emitting devices 132, 134L1, etc.) held in the ROM of the sub control board 1047a. Is extracted and stored in the output data buffer ("light emission data update process" S4308). The stored data is output by the device control process 4302 in the next periodic timer process S4206.

  After the light emission pattern data update process S4308, a process for synchronizing the light emission effect and the sound effect is executed ("light emission / sound synchronization process" S4309). After the light emission / sound synchronization processing S2405, in the situation where the sound effect is being performed, if the player is left for a predetermined time (30 seconds in this embodiment) without any input, The volume of the sound effect is changed to a low volume (“acoustic fade-out process” S4310). Further, it is confirmed whether or not a predetermined time (in this embodiment, 50 seconds) has passed without any input by the player, and a demonstration flag is set ("demonstration start confirmation process" S4311). A predetermined demonstration effect is started in the liquid crystal display device 1042 by setting the demonstration flag. After the demonstration start confirmation processing S4311, the volume setting of the volume adjustment switch (not shown) in the volume changing operation device (not shown) is confirmed, and the volume at the time of error notification or production for the speakers 1106 and 1204 is updated. ("Volume setting process" S4312).

  After the volume setting process S4312, data for controlling the liquid crystal display device 1042, the speakers 1106 and 1204, the light emitting devices 132 and 134L1, and the like are updated (“notification data change process” S4313).

[Main configuration related to the present invention]
The stop control of each of the stepping motors 1043L4, 1043M4, and 1043R4, which is the main characteristic part of the present invention in the spinning machine 1010, will be described in detail. Since the control of each stepping motor 1043L4, 1043M4, 1043R4 is substantially the same as described above, only the control of the right stepping motor 1043R4 will be described. Further, since the rotational torque received by each excitation phase in the front rotor 1060a and the back rotor 1060b in the stepping motor 1043R4 is substantially the same, only the relationship between the front rotor 1060a and each of the stators 1601 to 1604 will be described.

  In the constant speed driving state of the stepping motor 1043R4, the excitation phase information constituting the rotation excitation phase information sequence is sequentially selected in a predetermined order as shown in FIG. 1 type), (A + B) phase (a type of quasi-rotation excitation phase), B phase (a type of basic rotation excitation phase), (B + inverted A) phase (a type of quasi-rotation excitation phase), inverted A phase (a basic rotation excitation phase) ), (Reverse A + reverse B) phase (a kind of quasi-rotation excitation phase), reversal B phase (a kind of basic rotation excitation phase), and (reverse B + A) phase (a kind of quasi-rotation excitation phase) predetermined rotation excitation Excited in order. Thereby, the rotating drum R rotates at a constant speed. The combinations of the stators 1601A to 1601D excited by the respective rotational excitation phases and their polarities are as shown in FIG.

  Here, the phase interval between the passing position of the symbol and the rotation excitation phase in the vicinity of the displacement angle corresponding to the basic planned stop angle in the constant speed rotation state of the right rotating drum R will be described. FIGS. 32A to 32F are schematic explanatory views for explaining an example of the transition of the symbol movement in the constant speed rotation state of the stepping motor. 32A to 32F show the case where the symbol number is 0 (hereinafter referred to as the 0th symbol). FIGS. 33A to 33F are schematic explanatory views for explaining an example of the transition of the position change of the rotor in the constant speed driving state of the stepping motor.

  In FIG. 32A, the length in the rotation direction of the symbol is D, and the position at which the 0th symbol is completely displayed in the reference stop area 100 (FIG. 32C) is positioned by D / 12. Represents the case. FIG. 33A shows the positions of the salient poles of the rotor 1060 of the stepping motor 1043R4 and the salient poles of the stators 1601 to 1604 when the 0th symbol is located as shown in FIG. Represents. As can be seen from FIG. 33A, each of the salient poles of the fourth stator 1604 is completely opposed to the salient pole of the front rotor 1060a, and each of the salient poles of the first stator is the salient pole of the rotor 1060. The pitch is shifted by P / 4 with “P” as the pitch. When the front rotor 1604a and each of the stators 1601 to 1604 are in the positional relationship shown in FIG. 33A, the angle that is magnetically most stable with respect to the excitation of the reversed B phase (hereinafter referred to as “reversed B phase”). Is referred to as a “stable angle”. When the displacement angle reaches the stable angle of the reversed B phase, the excitation phase is changed from the reversed B phase to the rotation excitation phase next to the reversed B phase (reverse B + A) in the rotational excitation order. Due to excitation by the (reverse B + A) phase, the rotor 1604 rotates (moves in the right direction in FIG. 33A), and the 0th symbol moves (moves in the downward direction in FIG. 32A). 33B and the respective stators 1601 to 1604 are in a positional relationship as shown in Fig. 33. The displacement angle in this case is the most magnetically stable angle ((reversed B + A) with respect to the (reversed B + A) phase. When the displacement angle is the stability angle of the (reversed B + A) phase, the 0th symbol is D / 24 of the reference stop area 100 as shown in FIG. Located just in front.

  When the displacement angle reaches the stable angle of the (reverse B + A) phase, the excitation phase is changed to the A phase that is the next excitation phase after the (reverse B + A) phase. Thus, as shown in FIG. 32 (C), the 0th symbol is completely displayed in the reference stop area 100, and as shown in FIG. 33 (C), the first stator 1601 has a positional relationship. Each salient pole is in a state of completely facing any salient pole of the front rotor 1060a. The displacement angle in this case is the most magnetically stable angle with respect to the A phase (“the stable angle of the A phase”). The stators 1601 to 1604 and the front rotor 1060a have a positional relationship corresponding to the stable angle of the A phase for every excitation of all the rotational excitation phases. Here, when the phase A stable angle is θi (i is an integer of 0 to 63) and the displacement angle difference for each change of each excitation phase is θ ′ / 2, FIG. 32 (B) and FIG. Is expressed by θi−θ ′ / 2, and the displacement angle θ in the positional relationship shown in FIGS. 32A and 33B is θi. It is represented by −θ ′. In the following, θ ′ is also referred to as “step angle”, and θ ′ / 2 is also referred to as “drive step angle”. Further, θi + 4θ ′ = θ (i−1).

  When the displacement angle reaches the stable angle (θ = θi) of the A phase, the excitation phase is changed to the (A + B) phase that is the next excitation phase of the A phase. As a result, as shown in FIG. 32D, the positional relationship between the 0th symbol and the reference stop region 100 becomes a positional relationship in which the 0th symbol is shifted from the reference stop region 100 by D / 24. Each salient pole of the stator 1601 and the salient pole of the front rotor 1060a are in a positional relationship shifted by P / 24 as shown in FIG. The displacement angle (θ = θi + θ ′ / 2) in this case is the most magnetically stable angle with respect to the (A + B) phase (“(A + B) phase stable angle”).

  When the displacement angle reaches the stable angle of the (A + B) phase, the excitation phase is changed to the B phase that is the next excitation phase after the (A + B) phase. As a result, as shown in FIG. 32 (E), the 0th symbol is completely displayed in the reference stop region 100, and as shown in FIG. 33 (E), the second stator 1602 has a positional relationship. Each salient pole is completely opposed to one of the salient poles of the front rotor 1060a, and the salient poles of the first stator 1601 and the salient pole of the front rotor 1060a are displaced by D / 12.

  Similarly, when the displacement angle reaches the stable angle (θ = θi + θ ′) of the B phase, the excitation phase is changed to the (B + inversion A) phase that is the next excitation phase of the A phase, and (B + inversion) A) Shift to the most magnetically stable angle with respect to the phase (“(B + inverted A) phase stable angle”). After that, when the displacement angle reaches the stable angle (θ = θi + 3θ ′ / 2) of the (B + reverse A) phase, the excitation phase is changed to the reverse A phase that is the next excitation phase after the (B + reverse A) phase. Thus, the angle shifts to the magnetically most stable angle (“inversion A phase stability angle”) with respect to the inversion A phase. At the reverse A-phase stable angle, each salient pole of the third stator 1603 is in a state of completely facing any salient pole of the front rotor 1060a. Thereafter, when the displacement angle reaches the stable angle (θ = θi + 2θ ′) of the reversed A phase, the excitation phase is changed to the next excited phase of the reversed A phase (reversed A + reversed B), and (reversed) The angle shifts to the most magnetically stable angle with respect to the (A + inverted B) phase (“stable angle of (inverted A + inverted B) phase”). Thereafter, when the displacement angle reaches the stable angle (θ = θi + 5θ ′ / 2) of the (inverted A + inverted B) phase, the inversion B which is the next exciting phase after the (inverted A + inverted B) phase. The phase is changed to a phase that is magnetically most stable with respect to the inverted B phase (“stable angle of inverted B phase”). At the inverted A-phase stability angle, each salient pole of the first stator 1601 is in a state of completely facing any salient pole of the front rotor 1060a. Thereafter, when the displacement angle reaches the stable angle (θ = θi + 3θ ′) of the inverted B phase, the excitation phase is changed to the (exverse B + A) phase that is the next excitation phase of the inverted B phase, and (inverted B + A) The angle shifts to the most magnetically stable angle with respect to the phase (“(inverted B + A) phase stable angle”). Further, when the displacement angle reaches the stable angle (θ = θi + 7θ ′ / 2) of the (reversed B + A) phase, the excitation phase is changed to the A phase that is the next excitation phase after the (reversed B + A) phase. Returning to the phase stability angle (θi + 4θ ′ = θ (i−1)), as shown in FIG. 32 (F), the positional relationship between the 0th symbol and the reference stop region 100 is such that the 0th symbol is the reference stop. The positional relationship is shifted by D / 3 from the region 100, and the positional relationship between each salient pole of the first stator 1601 and the salient pole of the front rotor 1060a is shifted by P / 3 as shown in FIG. Become. Furthermore, when all the rotational excitation phases are excited twice in a cyclic manner, the first symbol is completely displayed in the reference stop area 100 as in the case of FIG.

  The rotational torque applied to the rotor 1060 by excitation by each rotational excitation phase will be described. FIG. 34 is a graph qualitatively illustrating an example of the transition of the rotational torque in the constant speed driving state of the stepping motor. The functions T_A, T_B, T_inversion A, and T_inversion B represented by solid lines represent rotational torques when A-phase excitation, B-phase excitation, inverted A-phase excitation, and inverted B-phase excitation are performed, respectively. Also, the functions T_AB, T_B inversion A, T_inversion A inversion B, and T_inversion BA represented by broken lines are respectively (A + B) phase excitation, (B + inversion A) phase excitation, (inversion A + inversion B) phase excitation and This shows the rotational torque when the (reverse B + A) phase excitation is performed. The positive side of the vertical axis represents the torque acting in the direction of rotating the right cylinder R, and the additional side represents the torque acting in the direction of rotating the right cylinder R in the reverse direction. For example, in the case of A-phase excitation, when the displacement angle θ deviates from θi, in the range of θi−2θ ′ <θ <θi, rotational torque works in the positive rotation direction so that the displacement angle becomes θi. On the other hand, in the range of θi <θ <θi + 2θ ′, rotation torque acts in the positive rotation direction so that the displacement angle becomes θi. Thus, in the range of θi−2θ ′ <θ <θi + 2θ ′, the point where the displacement angle is θi is magnetically most stable. Similarly for other functions, the displacement angle at which the rotational torque is changed from the positive side to the negative side intersects the horizontal axis and is the most magnetically stable angle with respect to the excitation phase according to the function.

  In the actual constant speed drive state, the excitation phase is changed according to the displacement angle, and therefore, as shown in FIG. 34, the rotational torque indicated by the function indicated by the thick solid line is received. Specifically, the front rotor 1060a receives the rotational torque specified by the function T (inversion B) in the range of (1) θi−3θ ′ / 2 <θ <θi−θ ′, and (2) θi−. In the range of θ ′ <θ <θi−θ ′ / 2, the rotational torque specified by the function T (reverse BA) is received. (3) In the range of θi−θ ′ / 2 <θ <θi, the function TA In the range of (4) θi <θ <θi + θ ′ / 2, the rotational torque specified by the function TAB is received, and (5) in the range of θi + θ ′ / 2 <θ <θi + θ ′. Receives the rotational torque specified by the function TB, and receives the rotational torque specified by the function T (B inversion A) in the range of (6) θi + θ ′ <θ <θi + 3θ ′ / 2, and (7) θi + 3θ ′ / In the range of 2 <θ <θi + 2θ ′, the rotation specified by the function T (inversion A) Receiving the torque, (8) In θi + 2θ '<θ <θi + 5θ' / 2 in the range, it undergoes a rotational torque that is specified by a function T (inversion BA). Note that the function indicated by the bold solid line is a periodic function of 4θ ′.

  The non-excitation holding torque applied to the front rotor 1060a in the non-excitation state will be described. FIG. 35 is a graph qualitatively showing an example of the non-excitation holding torque. In FIG. 35, for comparison, a graph that qualitatively expresses the rotational torque with respect to the A-phase excitation is also indicated by a broken line. As shown in FIG. 35, even in the non-excited state, the stators 1601 to 1604 are magnetized when the front rotor 1060a is magnetized, and the magnetic force between the front rotor 1060a and each of the stators 1601 to 1604 is magnetic. The non-excited holding torque specified by the solid line function Td is received by a large stress. The function Td is a function in which the non-excitation holding torque between the front rotor 1060a and each of the stators 1601 to 1604 is superimposed, and is a periodic function of the θ ′ period. Since the non-excitation holding torque between the front rotor 1060a and each of the stators 1601 to 1604 differs depending on the positional relationship between the front rotor 1060a and each of the stators 1601 to 1604, Td obtained by superimposing these is the period θ ′. Increase or decrease in complexity. However, since detailed increase / decrease is not necessary to qualitatively explain the operational effects of the present invention, FIG. 35 shows a function that increases and decreases monotonically like a sine function. In this embodiment, the maximum value of the non-excitation holding torque is approximately 1/7 of the maximum value of the rotational torque for the A-phase excitation. In the non-excited state, the stable angle of the A phase (θ = θi), the stable angle of the B phase (θi + θ ′), the stable angle of the reversed A phase (θi + 2θ ′), and the stable angle of the reversed B phase (θi + 3θ ′, θi−θ All of ') are the most magnetically stable angles. Therefore, even in the non-excited state, the right cylinder R will eventually stop at an angle corresponding to one of these stable angles.

  The stop control of the right cylinder R in this embodiment will be described in detail. As described above, in the right stepping motor 1043R4, each rotation excitation phase is cyclically excited according to a predetermined rotation excitation sequence, whereby the right cylinder R rotates at a constant speed. When the right-turn cylinder stop button 1126R (see FIG. 1) is operated by the player, a right stop signal (stop instruction) is input to the main control board 1045a. The main control board 1045a (see FIG. 15) monitors the right stop signal. When the right stop signal is received, the RAM 1045a3 (see FIG. 15) of the main control board 1045a shows the right stop signal reception flag indicating reception of the right stop signal. Is set (switch reading process S2108 and sensor monitoring process S2109 in FIG. 16). Further, the main control board 1045a monitors the setting state of the right stop signal reception flag (determination processing S2608 in FIG. 23), and when the right stop signal is received (S2608: Y), the right turn cylinder After confirming whether R is in a constant speed rotation state and determining whether it is necessary to change the reference control table referred to in the stop control of the right cylinder R (determination processing S2621 to FIG. 23, resetting the control table) In the process S2623), stop control of the right cylinder R is started (right cylinder stop process S2624 in FIG. 23). When the right cylinder R has already been stopped, the stop control of the right cylinder R is not started, and when the reference control table needs to be changed, the right cylinder is rotated after the change. The stop control of the trunk R is started.

  When the stop control of the right cylinder R is started, a symbol (scheduled symbol to be stopped) to be stopped in the reference stop region 100 (see FIG. 32) constituting the lower combination line is determined (right cylinder stop process S2622). . Specifically, the symbol number is determined. In this embodiment, for each symbol, the symbol offset value corresponding to the stop position is the same (“0” or “2”) and two types (“0” or “2”). By determining, the basic stop scheduled angle and the auxiliary stop angle of the right cylinder R are substantially determined. Two types of planned stop angle information corresponding to the planned basic stop angle and the planned auxiliary stop angle are set in [stop symbol number, 0] and [stop symbol number, 2], respectively. When the planned stop angle information is set, referring to the symbol number and symbol offset values monitored on the main control board 1045a, the combination of these is clockwise until the combination matches the two types of planned stop angle information. The normal rotation of the trunk R is continued (determination process S101 to determination process S112 in FIG. 17). Except for special cases, because the basic stop planned angle is selected, the following will describe the case of stopping at the basic stop planned angle, and then the basic stop when stopping at the auxiliary stop planned angle. Only differences from the planned angle will be described.

  When the combination of the symbol number and symbol offset value matches [stop symbol number, 0] (stop start determination processing S110 to 112: Y), cyclic excitation of each rotational excitation phase in accordance with the rotational excitation sequence. Is completed (acceleration counter release processing S113), and excitation in accordance with the stop excitation sequence in which all phases-A phase (specific phase) -all phases are sequentially selected is started (deceleration counter setting processing S114). First, all phases corresponding to the first stop excitation order are set as excitation phases (all phase setting processing), and all phase excitation times for performing all phase excitation are set (wait timer resetting processing S115). Note that all-phase excitation is executed after (reverse B + A) phase excitation in the rotation excitation order. All-phase excitation is maintained until the all-phase excitation time has elapsed (determination processing S101 to wait timer update processing S102). When the all-phase excitation time has ended (determination process S101: Y, determination process S103: N and determination process S119: N), the excitation phase is changed from all phases to the second A phase in the stop excitation sequence ( A phase excitation time (specific phase excitation time) for exciting the A phase is set together with the specific phase setting processing S121) (wait timer setting processing S120). The A-phase excitation is maintained until the A-phase excitation time elapses (determination process S101 to wait timer update process S102). When the A phase excitation time has ended (determination process S101: Y, determination process S103: N, determination process S119: Y), the excitation phase is changed from the A phase to the last all phases in the stop excitation sequence (specification). Together with the phase setting process S123), the A phase excitation time (specific phase excitation time) for exciting the A phase is set (wait timer setting process S122). When the all-phase excitation time again ends (determination process S101: Y, determination process S103: Y), all-phase excitation is released and the state is shifted to the non-excitation state (demagnetization process S124).

  Here, prior to the detailed description of the drive control of the right stepping motor 1043R4 according to the stop excitation order of this embodiment, for the convenience of the description, (1) a transition from the constant speed drive state to the non-excitation state and the right When stopping the rotating cylinder R, (2) When stopping the right rotating cylinder R by excitation of a specific one-phase excitation phase (specifically, A phase) from the constant speed driving state, (3) Constant speed driving A case where the right cylinder R is stopped by excitation of only the all-phase excitation phase from the state will be described.

  (1) The case where the right cylinder R is stopped by shifting from the constant speed drive state to the non-excitation state will be described. FIG. 36 is a graph qualitatively showing an example of the transition of torque in the deceleration drive state by the excitation release. For comparison with the case of the present embodiment, a case where (reverse B + A) phase excitation is canceled after (reverse B + A) phase excitation will be described. When the (reverse B + A) phase excitation is canceled after the (reverse B + A) phase is excited, as shown in FIG. 36, it is indicated by a thick broken line in an angle range satisfying θi−θ ′ / 2 <θ. In response to the stress caused by the non-excitation holding torque along the path P ″, the right cylinder R stops. In this case, the position where the speed of the right cylinder R first becomes “0” is θi−θ ′ / 2 <. If the angle range satisfies θ <θi + θ ′ / 2, once the speed of the right cylinder R is “0”, the rotor is drawn to a stable angle that satisfies θ = θi and the cylinder is completely stopped. Further, if the position at which the speed of the right turn cylinder R first becomes “0” is an angle range satisfying θi + θ ′ / 2 <θ <θi + 3θ ′ / 2, it is drawn into a stable angle satisfying θ = θi + θ ′. The rotating cylinder stops completely. Furthermore, when the position where the speed of the right cylinder R first becomes “0” is shifted farther than that, the right cylinder R completely stops at a stable angle at a displacement angle exceeding θi + θ ′. Become.

  (2) A case will be described in which the right cylinder R is stopped by exciting only a specific one-phase excitation phase (specifically, the A phase) from the constant speed driving state. FIG. 37 is a graph qualitatively showing an example of torque transition in the deceleration drive state by phase A excitation. For comparison with the case of the present embodiment, a case where A phase excitation is performed after (inverted B + A) phase excitation will be described. When the A phase is excited after exciting the (inverted B + A) phase, as shown in FIG. 37, in the angle range satisfying θi−θ ′ / 2 <θ, the path P ′ indicated by the thick broken line In response to the stress due to the torque along, the right cylinder R stops. Specifically, in this case, if the position at which the speed of the right turn cylinder R first becomes “0” is an angle range that satisfies θi−θ ′ / 2 <θ <θi + 2θ ′, After the speed becomes “0”, the rotating drum is completely stopped by being drawn to a stable angle satisfying θ = θi. Furthermore, when the position where the speed of the right cylinder R first becomes “0” is shifted farther than that, the right cylinder R completely stops at the stable angle of the A phase at the displacement angle exceeding θi + 2θ ′. Will be. In addition, when the A phase is excited after exciting the (reverse B + A) phase, it is the same as the constant speed driving state, so the torque by the A phase for substantially stopping the rotation of the rotating cylinder has a displacement angle. It will act from when θi is exceeded.

  (3) The case where the right cylinder R is stopped by the excitation of only the all-phase excitation phase from the constant speed driving state will be described. FIG. 38 is a graph qualitatively showing an example of the transition of torque in the deceleration drive state by the all-phase excitation phase. In FIG. 38, for convenience of explanation, the front rotor 1060a (rotary shaft) is forcibly rotated at the same constant speed in the steady rotation state by an external force with all phases excited. An example of the transition of the additional torque in this case is qualitatively represented (dotted line Ti0 in the figure). When all the phases are excited and the front rotor 1060a is not rotating or when the rotational speed is extremely low, torque is received only from the non-excitation holding torque that is the same as the non-excitation state. In the all-phase excitation, when the A phase, the B phase, the inverted A phase, and the inverted B phase are excited, as can be inferred from FIG. 14, the first stator 1601 is excited to the S pole by the A phase. At the same time, since the N pole is excited by the inverted A phase, the magnetization due to the A phase and the magnetization due to the B phase cancel each other and become substantially the same as in the non-excited state. Similarly, the second stator 1602, the third stator 1603, and the fourth stator 1604 are substantially in a non-excited state. However, since the wirings W1 to W4 (see FIG. 12) for exciting the stators 1601 to 1604 are short-circuited to the power source, the current flowing through them can be changed as necessary. In the non-excited state, since the wires W1 to W4 are opened from the power source, no current flows through them. Therefore, in the case of all-phase excitation, the magnetization of each stator 1601 to 1604 and the relative position with respect to the front rotor 1060a change between the front rotor 1060a and each stator 1601 to 1604 according to the rotation of the front rotor 1060a. The magnetic flux density changes. In response to the change in the magnetic flux density, an induced current is generated in the wirings W1 to W4 corresponding to the magnetization of the stators 1601 to 1604 and the relative position with the front rotor 1060a so as to cancel the change in the magnetic flux density. Due to this induced current, the value of the current flowing through each of the wirings W1 to W4 changes. Therefore, in the case of all-phase excitation, a torque obtained by superimposing a non-excitation holding torque and a torque accompanying excitation by an induced current (hereinafter referred to as “induction torque”) is received. Therefore, when all the phases are excited and the front rotor 1060a (rotating shaft) is forcibly rotated by the external force at the same constant speed in the steady rotation state, it is indicated by a dotted line in FIG. Such induction torque Ti0 is received. In addition, when the rotation direction is reversed, torque having a polarity opposite to that of the induction torque Ti0 is received. In actual stopping of the rotating drum R, since the rotational speed changes, the induction torque Ti0 is multiplied by a coefficient corresponding to the change in the rotational speed, so that the induction torques Ti1 to Ti3 as shown by the solid line are received. The induction torque Ti1 represents a case where the operation is normally stopped, the induction torque Ti2 represents a case where only a weak stress is applied in the direction of stopping rotation than usual, and the induction torque Ti3 is applied with a stronger stress in the direction of stopping rotation than normal. Represents the case. Since each induction torque Ti1 to Ti3 depends on the rotational speed, it acts in a minute time immediately after the start of the stop, for example, a time required to rotate by θ ′ / 2. The holding torque Td becomes dominant and its influence is extremely small. Although not shown in FIG. 38, stress due to rotational friction caused by the rotation shaft of the stepping motor 1043R4 is also acting.

  In the normal case, the stop is started at the point I (θ = θi−θ ′ / 2), and the rotating drum R moves the point M (θ> θi) by the rotational friction, the non-excitation holding torque Td, and the induction torque Ti1. It stops at the point F (θ = θi) via the route. Even when the restraining stress is larger than usual, the rotating drum R stops at the point F (θ = θi) due to the rotational friction, the non-excitation holding torque Td, and the induction torque Ti3. However, when the restraining stress is smaller than usual, the rotating drum R stops at θ = θi + θ ′ due to the rotational friction, the non-excitation holding torque Td, and the induction torque Ti3. Specifically, when the position where the speed of the rotating drum R first becomes “0” exceeds θ = θi + θ ′ / 2 or exceeds θ = θi + θ ′ / 2, the speed of the rotating drum R is “0”. If not, the rotating drum R stops at θ = θi + θ ′. As can be seen from FIG. 38, when stopping the rotating cylinder R by all-phase excitation, compared to stopping the rotating cylinder in the non-excited state (θi−θ ′ / 2 <θ By receiving additional induction torques Ti1 to Ti3 in the direction of stopping the rotation of the rotating drum R in <θi−θ ′ / 4), the rotating speed of the rotating drum R is rapidly reduced.

  Here, the case where the rotating drum R is stopped by the basic stop excitation sequence (all-phase excitation-A-phase excitation-all-phase excitation) of this embodiment will be described in detail. FIG. 39 is a graph qualitatively showing an example of transition of the rotational speed of the rotating drum. Note that FIG. 39 shows an example (P ′, P ″) of transition of the rotational speed when the rotating drum R is stopped only by all-phase excitation and when the rotating drum R is stopped only by A-phase excitation. First, when the start lever is operated (time Ti), acceleration of the rotating drum R is started, and a predetermined acceleration period (213 interruption of timer interruption processing of the main control board 1035a) is started. After a period (about 317.37 ms), a constant speed is reached (time T1) When the rotation stop button is operated when the rotation speed of the rotation R is constant (time T2), depending on the planned stop position When the stop start determination determines that the rotation of the rotating drum R is stopped (displacement angle information = [stop symbol number, 0] or [stop symbol number, 2]) (T3). ), The rotation of the rotating drum R is started, and the speed change P The rotational speed of the rotating drum R is changed along with it, and the rotating drum R stops completely (time Tf). Changes along the speed change P ′, and when the rotating drum R is stopped only by all-phase excitation, it changes along the speed change P ″.

  When stopping the rotating drum R by the basic stop excitation sequence (all-phase excitation-A-phase excitation-all-phase excitation), specifically, as shown in FIG. 38, the point I (θ = θi−θ '/ 2) starts to stop (corresponding to time T3), and is only for a predetermined all-phase excitation time (specifically, 11 interrupt periods (about 16.39 ms) of timer interrupt processing of the main control board 1035a). Phase excitation is performed. In this case, rotational friction, non-excitation holding torque Td, and induction torques Ti1 to Ti3 corresponding to the situation are received. When normal, the displacement angle of the rotating drum R is in the vicinity of θi, and in the abnormal case where the induction torque Ti2 is received, it is an angle that greatly exceeds θi (for example, near θ = θi + θ ′ / 2). . Thereafter, the excitation phase is changed from all phases to the A phase, and the A phase is applied for a predetermined A phase excitation time (specifically, three interrupt periods (about 4.47 ms) of the timer interrupt processing of the main control board 1035a). Excitation is performed. In this case, rotational torque TA is received as shown in FIG. As described with reference to FIG. 37, the rotational torque TA generates a stronger stress in the direction of θi−2θ ′ <θ <θi + 2θ ′ than in the case of full-phase excitation in the direction of pulling in or stopping at the displacement angle θi. Let In the normal case, the rotating drum R is completely stopped by the A-phase excitation. On the other hand, even in an abnormal case according to the induction torque Ti3, in the angle range of θi−2θ ′ <θ <θi + 2θ ′, a stronger stress is generated in the direction in which the displacement angle θi is drawn or stopped than in the normal case. . As a result, after the A-phase excitation, the displacement angle satisfies θ <θi + θ ′ / 2, and the rotating drum R can be in a state where the rotation speed is “0” or rotating in the reverse rotation direction. After that, the excitation phase is changed again from the A phase to the all phase, and the excitation phase is changed only for a predetermined all phase excitation time (specifically, the 146 interrupt period (about 217.54 ms) of the timer interrupt processing of the main control board 1035a). Phase excitation is performed. When the rotating drum R is not completely stopped in the A phase excitation, the rotating drum R is completely stopped by the rotational friction, the non-excitation holding torque Td and the induction torque (not shown) according to the all phase excitation. Will be. It should be noted that even when the rotating cylinder R stops at θ = θi + θ ′ as in the case of receiving the induction torque Ti2 in FIG. 38 only by all-phase excitation, the displacement angle is θ <θi + θ ′ / 2 is satisfied and the rotating drum R is rotated in the rotational speed “0” or in the reverse rotation direction, the rotating drum R can be completely stopped at θ = θi in the all-phase excitation again.

  Here, the case where the rotating drum R is stopped by the auxiliary stop excitation sequence (all-phase excitation-B-phase excitation-all-phase excitation) of this embodiment will be described. In this embodiment, in preparation for an unexpected situation, when the stop cannot be started at the point I (θ = θi−θ ′ / 2), the stop is started at θ = θi + θ ′ / 2, and θ = θi + θ ′. Thus, the rotating cylinder R is completely stopped. Even in this case, since the one-phase excitation phase selected between all-phase excitations is the B phase, since the stress that is substantially the same as that in the case of the basic stop excitation sequence is applied when the rotor R is stopped, the basic stop excitation is performed. Substantially the same stop can be performed as when stopping by order. Moreover, the action and effect are substantially the same.

  After stopping the rotating drum R by the basic stop excitation sequence and the auxiliary stop excitation sequence, the all-phase excitation for the rotating drum R is released again. In the next unit game, when the rotating drum R is stopped according to the basic stop excitation order in the previous unit game, the start excitation phase in the acceleration driving state of the stepping motor 1043R4 is set to the A phase, and the previous unit game When the rotating drum R is stopped in accordance with the basic stop excitation sequence, the start excitation phase in the acceleration driving state of the stepping motor 1043R4 is set to the B phase.

  In the case of the gaming machine of this embodiment, in the stop driving state of the stepping motors 1043L4, 1043M4, and 1043R4, the deceleration angle is not sufficiently reduced by all-phase excitation preceding the A phase (basic excitation phase), and the displacement angle becomes the basic stop scheduled angle ( Even if the pull-in angle range by all phases centering on θ = θi) is exceeded, the pull-in angle range around the planned stop angle by phase A (basic excitation phase) is the pull-in angle range by all-phase excitation phases. Therefore, the rotor R can be pulled back into the pull-in angle range by all phases (substantially non-excited holding torque) as long as it is within the pull-in angle range by the A-phase. This improves the accuracy of stopping the drums L, M, and R at a predetermined scheduled stop angle.

  Similarly, in the stop driving state of the stepping motors 1043L4, 1043M4, and 1043R4, the displacement angle is centered on the planned basic stop angle (θ = θi) without sufficient deceleration due to all-phase excitation preceding the B phase (auxiliary excitation phase). Even if the pull-in angle range by the all-phase excitation phase is exceeded, the pull-in angle range around the planned stop angle by the B-phase is larger than the pull-in angle range by the all-phase excitation phase. As long as it is within the pull-in angle range, it can be pulled back into the pull-in angle range by the all-phase excitation phase by the A phase. This improves the accuracy of stopping the drums L, M, and R at a predetermined scheduled stop angle. In addition, if control for stopping at the basic stop scheduled angle (θ = θi) is not possible due to unforeseen circumstances, the next stabilization by all-phase excitation (non-excited holding torque in the non-excited state) of the basic stop planned angle By stopping according to the angle, it is possible to prevent each of the cylinders L, M, and R from stopping after a stop operation by the player is performed and the player is rotated one or more times.

  Further, by making the start excitation phase in the acceleration drive state of the stepping motors 1043L4, 1043M4, and 1043R4 for the next unit game the same as the one-phase excitation phase in the stop drive state of the stepping motor in the previous unit game, At the start of driving, each cylinder L, M, R can be smoothly rotated.

  As shown in FIG. 39, the rotational speed of each of the cylinders L, M, and R when reaching the planned stop angle is lower than that when decelerated by A-phase excitation without going through all-phase excitation phases. As can be seen from the comparison between the rotational speed change P and the rotational speed change P ′, the maximum vibration width of the rotating cylinder in the vicinity of the planned stop angle is reduced and the vibration times of the rotating cylinders L, M, and R are shortened. Therefore, the stop to the planned stop angle becomes smooth. Further, when the stress for stopping the rotating drum R is smaller than that in the normal case, the rotating drum R is smoothly stopped even in such a case by performing all-phase excitation again after the A-phase excitation. Can do. This is because when the A-phase excitation is continued without performing all-phase excitation again, the reverse rotation speed is increased by the rotational torque TA, and the vibration in the vicinity of the planned stop angle is increased.

  In the above, a rotation excitation phase information sequence (see FIG. 18A) in which a plurality of types of rotation excitation phase information is ordered in substantially the same order as a predetermined rotation excitation order is stored in the data area of the ROM 1045a2 of the main control board 1045a. All phase information corresponding to all phase excitation phases is held in the program area of the ROM 1045a2 of the main control board 1045a, and the stepping motors 1043L4, 1043M4, and 1043R4 are driven to rotate by referring to the rotation excitation phase information sequence. Is controlled, and stop driving of each of the stepping motors 1043L4, 1043M4, and 1043R4 is controlled with reference to the rotation excitation phase information corresponding to the A phase and the B phase and the all phase excitation phase information in the rotation excitation phase information sequence. Although described, other data holding methods and other data reference methods may be used. For example, a stop excitation phase information group including all phase information corresponding to all phase excitation phases, A phase information corresponding to A phase (basic excitation phase), and B phase information corresponding to B phase (auxiliary excitation phase) is mainly used. The stop drive of each of the stepping motors 1043L4, 1043M4, and 1043R4 may be controlled by referring to only the stop excitation phase information group in a predetermined order, which is held in the data area of the ROM 1045a2 of the control board 1045a. Also, the previous all-phase excitation phase information corresponding to the all-phase excitation phase selected before the A phase (basic excitation phase), the specific excitation phase information corresponding to the A phase, and the all-phase excitation phase selected after the A phase. After all phase excitation phase information corresponding to the stop excitation phase information sequence ordered in the predetermined basic stop excitation sequence, and all previous phases corresponding to all phase excitation phases selected before B phase (auxiliary excitation phase) Auxiliary stop excitation phase information in which excitation phase information, specific excitation phase information corresponding to B phase, and all subsequent phase excitation phase information corresponding to all phase excitation phases selected after B phase are ordered in a predetermined auxiliary stop excitation order Are stored in the data area of the ROM 1045a2 of the main control board 1045a, and each stepping motor 1043L4 is selectively referred to by referring to the basic stop excitation phase information row or the auxiliary stop excitation information row according to the stop start determination condition. , 1043M4,1043R Of it may be controlled to stop driving.

  In the above description, based on the positive determination of the stop start determination, the stable angle (θ = θ) of the non-excited state closest to the displacement angle (θ = θi−θ ′ / 2) at the start of stop of the rotating cylinders L, M, and R Although it is stopped at θi), it may be stopped at stable angles (for example, θ = θi + θ ′, θi + 2θ ′) having a displacement angle larger than the stable angle in the most recent non-excitation state.

  In the above, in the stop driving of each of the stepping motors 1043L4, 1043M4, and 1043R4, two types including the basic excitation phase (A phase) and the auxiliary excitation phase (B phase) as specific excitation phases according to the stop start determination conditions. Although the excitation phase is selected, in the present invention, the specific excitation phase may be one type of excitation phase. In the present invention, there may be three or more specific excitation phases. In the case of three or more types, it is preferable that there are at most two types in order to increase the deviation width of the stop position between the types and affect the visibility.

  In the above description, the case where the stepping motors 1043L4, 1043M4, and 1043R4 are controlled by the one-phase to two-phase excitation drive has been described. However, the stepping motors 1043L4, 1043M4, and 1043R4 may be controlled by the one-phase excitation drive or the two-phase to two-phase excitation drive. Here, a case where the stepping motors 1043L4, 1043M4, and 1043R4 are controlled by one-phase excitation drive will be described. FIG. 40 is a graph qualitatively showing another example of the transition of the rotational torque in the constant speed driving state by the one-phase excitation driving. FIG. 41 is a graph that qualitatively represents an example of a change in torque transition in the deceleration drive state with all-phase excitation phases. In the case of one-phase excitation driving, rotation driving is performed only by the A phase, B phase, inverted A phase, and inverted B phase. In the constant speed rotation state, as shown in FIG. 40, the rotation torque TA due to the A phase, the rotation torque TB due to the B phase, the rotation torque TA− due to the reverse A phase, and the rotation torque TB− due to the reverse B phase are received. When stopping the rotating drum R by the stop excitation sequence (all phase excitation-A phase excitation-all phase excitation), specifically, as shown in FIG. 41, the point I (θ = θi−θ ′) ) Is stopped, and all phase excitation is performed for a predetermined all phase excitation time. In this case, rotational friction, non-excitation holding torque Td, and induction torques Ti4 and Ti5 corresponding to the situation are received. In the normal case of receiving the induction torque Ti4, the angle is near θ = θi−θ ′ / 2, and in the abnormal case of receiving the induction torque Ti2, an angle that does not reach θi−θ ′ / 2 (for example, θ = θi−3θ ′ / 2 vicinity). Thereafter, the excitation phase is changed from all phases to A phase, and A phase excitation is performed for a predetermined A phase excitation time. In this case, rotational torque TA is received as shown in FIG. As described with reference to FIG. 37, the rotational torque TA generates a stronger stress in the direction of θi−2θ ′ <θ <θi + 2θ ′ than in the case of full-phase excitation in the direction of pulling in or stopping at the displacement angle θi. Let In the normal case, the rotating drum R is completely stopped by the A-phase excitation. On the other hand, even in an abnormal case according to the induction torque Ti5, in the angle range of θi−2θ ′ <θ <θi + 2θ ′, a stronger stress is generated in the direction in which the displacement angle θi is drawn or stopped than in the normal case. . Thus, after the A-phase excitation, the displacement angle satisfies θi + θ ′ / 2 <θ, and the rotating drum R can be in a state where the rotation speed is “0” or rotating in the forward rotation direction. Thereafter, the excitation phase is changed again from A phase to all phases, and all phase excitation is performed for a predetermined all phase excitation time. When the rotating drum R is not completely stopped in the A phase excitation, the rotating drum R is completely stopped by the rotational friction, the non-excitation holding torque Td and the induction torque (not shown) according to the all phase excitation. Will be. Note that, even when the rotating drum R stops at θ = θi−θ ′ as in the case of receiving the induction torque Ti5 in FIG. 38 only by all-phase excitation, the displacement angle is θ <θi + θ by A-phase excitation. When '/ 2 is satisfied and the rotating drum R is rotated in the rotational speed “0” or in the reverse rotating direction, the rotating drum R can be completely stopped at θ = θi in the all-phase excitation again. it can.

  In the above description, the case where the stepping motors 1043L4, 1043M4, and 1043R4 are two-phase stepping motors has been described. However, in the present invention, other stepping motors such as a three-phase stepping motor and a five-phase stepping motor may be used.

  In the above description, the stepping motors 1043L4, 1043M4, and 1043R4 are decelerated and driven. In the present invention, the excitation time of each excitation phase is a multiple of the excitation time of each excitation phase during steady rotation. The excitation time of each excitation phase in the deceleration drive state may not be a positive multiple of the excitation time. In this case, since the drive control processing of the stepping motors 1043L4, 1043M4, and 1043R4 on the main control board 1045a is complicated, the above configuration is preferable. The same applies to the excitation time of each excitation phase in the acceleration drive state. In the above description, the case where smooth acceleration and deceleration of the cylinders L, M, and R is performed by changing the excitation time of the excitation phases that are sequentially selected in the acceleration drive state and the deceleration drive state has been described. The excitation voltages of the excitation phases that are sequentially selected may be changed. In this case, since the configuration of the motor driver 1070 of each of the stepping motors 1043L4, 1043M4, and 1043R4 is complicated, it is preferable to control the acceleration and deceleration of the rotating cylinder according to the excitation time of each excitation phase as described above.

  The present invention is suitable for a gaming machine such as a swivel type gaming machine.
