  The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is repeatedly operated between an open state in which a game ball is easy to win and a normal closed state in the event of a big win. ing. More specifically, when a game ball wins the first start opening 33, the symbols are displayed in a variable manner on the first symbol main display device 42, and the confirmed symbol after the stop is a combination of specific symbols set in advance. A special gaming state occurs with the necessary conditions. The large winning opening of the variable winning device 32 is in a predetermined open state, and the game ball is configured to be in a state where it is easy to win a prize (a big hit state). Specifically, the passage of a predetermined time or a predetermined number of winnings is defined as one round, and the big winning opening of the variable winning device 32 is repeatedly opened a predetermined number of times. The number of times that the game ball has passed through the first start port 33 is held up to a maximum of 4 times, and the number of times that the game ball is held is lit and displayed by the hold lamp 46. Note that the hold lamp 46 may be configured so as to be variably displayed on a part of the first symbol main display device 42.

  Further, the game board 30 is provided with a rail unit 50 for guiding the game ball launched from the game ball launching device 38 to the upper part of the game board 30, and is launched in accordance with the turning operation of the game ball launch handle 18. The played game balls are guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product (for example, a molded product added with fluororesin), and has an inner rail 51 and an outer rail 52 that are integrally formed in an inner and outer double. . The inner rail 51 is formed in a substantially annular shape except for about ¼ of the upper portion, and an outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51. In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a spherical guide passage is formed by a portion (the left portion facing) where the rails 51 and 52 are parallel to each other at a predetermined interval. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip portion of the inner rail 51. This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 51 and the outer rail 52 to the upper part of the game board 30 returns to the ball guide path again. Yes. Further, a return rubber 54 is attached to the outer rail 52 at a position corresponding to the maximum flight portion of the game ball (a portion corresponding to the tip of the outer rail 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back. On the inner surface of the outer rail 52, there is a sliding plate 55 as a long metal strip made of stainless steel to make the flight of the game ball smoother, that is, to reduce the frictional resistance of the game ball. It is attached.

  An arc-shaped flange 56 projecting outward is formed on the outer peripheral portion of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, screws or the like are inserted into a plurality of through holes formed in the flange 56.

The convex portion 57 is provided in a substantially vertical direction from the inner rail 51 to the lower end portion of the rail unit 50, and guides a foul ball that does not reach the game area and flows backward in the ball guide passage to a foul ball passage (not shown). To play a role. The lower right corner and the lower left corner of the game board 30 are spaces for sticking stickers (S1 and S2 in FIG. 2) and plates such as stamps (for example, a serial number is described). In order to secure this adhering space, notches 58 and 59 are formed in the flange 56. By sticking stickers S1 and S2 such as a certificate paper to the lower right corner and the lower left corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

  Here, the front frame set 14 described above will be described in more detail with reference to FIG. The front frame set 14 is formed with a substantially elliptical window 101 so that most of the game area can be visually recognized from the outside. Specifically, the window portion 101 has a shape in which a substantially central portion on the left and right sides is curved relatively gently as compared with the upper and lower sides. The substantially central portion may be linear.

  The front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state in the big hit game state or when the blade is opened. For example, at the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED is provided symmetrically, and at the center of the annular illumination portion 102 and at the top of the pachinko machine 10, Similarly, a central illumination unit 103 having a built-in light emitting means such as an LED is provided. In the pachinko machine 10, the central illumination unit 103 functions as a jackpot lamp, and lights and blinks during the jackpot gaming state to notify that the jackpot gaming state is in progress. Further, the upper plate 19 is also provided around the upper plate 19 with an upper plate illumination unit 104 having a built-in light emitting means such as an LED. In addition, on the left and right sides of the central illumination unit 103, there are provided a prize ball lamp 105 that is lit during the payout of a prize ball and an error display lamp 106 that is lit when a predetermined error occurs. Further, a small window 107 made of a transparent resin is provided so as to be adjacent to the lower end portion of the annular illumination portion 102 so that a part of the inner frame 12 surface, the game board 30 surface, or the like can be visually recognized. Since the predetermined portion of the small window 107 is flat, the certificate paper or the like attached to the lower right corner of the game board 30 can be suitably read from the flat portion of the small window 107 by a machine.

  In addition, a ball lending operation unit 120 is disposed below the window unit 101, and the ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. When the ball lending operation unit 120 is operated with a bill or a card inserted in a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. Done. The ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. Is done. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. Note that the ball lending operation unit 120 is not required for a pachinko machine in which a game ball is directly rented from the ball lending device unit to the upper plate without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

  As shown in FIGS. 3 and 4, an operation unit 600 of the open detection switch SW <b> 1 (see FIG. 6) is provided on the upper surface of the inner frame 12 so as to be able to appear and retract. When the front frame set 14 (corresponding to the glass frame) is opened, the operation unit 600 protrudes to the front side as shown by the solid line in FIG. 4, thereby changing the switching of the open detection switch SW1 to detect the open state. it can. On the other hand, when the front frame set 14 (corresponding to the glass frame) is closed, the operation unit 600 is pushed in as shown by a two-dot chain line in FIG. 4, thereby changing the switching of the open detection switch SW1. The closed state can be detected. The processing operation related to the opening detection switch SW1 when the front frame set 14 is opened to eliminate the ball clogging will be described later.

The input side of the input port 527 is connected to the output side of the main controller 261, and the output side of the input port 527 is connected to the MPU 521, ROM 522, work RAM 523, image controller 526, and output port via the bus line 530. 528 is connected. A sound / lamp control device (also referred to as a sound / lamp control board) 262 is connected to the output side of the output port 528. Further, an output port 529 is connected to the image controller 526 via a bus line 531, and the first symbol display device 42 is connected to the output side of the output port 529.

  The MPU 521 of the display control device 45 controls the display of the first symbol display device 42 based on the symbol display command transmitted from the main control device 261. The ROM 522 is a memory for storing various control programs executed by the MPU 521 and fixed value data, and the work RAM 523 is for temporarily storing work data and flags used when the MPU 521 executes various programs. Memory.

  The video RAM 524 is a memory for storing display data displayed on the first symbol display device 42, and the display content of the first symbol display device 42 is changed by rewriting the contents of the video RAM 524. The character ROM 525 is a memory for storing character data such as symbols displayed on the first symbol display device 42. The image controller 526 adjusts the timings of the MPU 521, the video RAM 524, and the output port 529 to intervene in reading and writing data, and reads display data stored in the video RAM 524 from the character ROM 525 at a predetermined timing. The symbols are displayed on the display device 42 in the order of the layers in which the priorities are determined.

  The power supply device 313 includes a power supply unit 541 for supplying power to each unit of the pachinko machine 10, a power failure monitoring circuit 542 for monitoring power interruption due to a power failure and the like, and a RAM having a reset button 543a for RAM erasure (see FIG. 23). And an erasing switch circuit 543. The power supply unit 541 supplies necessary operating voltages to the main control device 261, the payout control device 311 and the like through a power supply path (not shown). As its outline, the power supply unit 541 takes in a voltage of 24 volts AC supplied from the outside, drives a switch, a motor, etc., has a voltage of 12 volts, a voltage of 5 volts for logic, and a RAM backup. A backup voltage or the like is generated, and the 12 volt voltage, the 5 volt voltage, and the backup voltage are supplied to the main controller 261, the payout controller 311, and the like. The firing control device 312 is supplied with operating voltages (12 volts and 5 volts) via the payout control device 311.

  The power failure monitoring circuit 542 is a circuit for outputting a power failure signal SG1 to each NMI terminal of the MPU 501 of the main control device 261 and the MPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541. The power failure signal SG1 is output to the main controller 261 and the payout controller 311. By the output of the power failure signal SG1, the main controller 261 and the payout controller 311 recognize the occurrence of the power failure and execute the NMI interrupt process. The power supply unit 541 outputs a voltage of 5 volts, which is the drive voltage of the control system, for a time sufficient to execute the NMI interrupt processing even after the DC stable voltage of 24 volts becomes less than 22 volts. Is maintained at a normal value. Therefore, the main controller 261 and the payout controller 311 can normally execute and complete the NMI interrupt process.

  The RAM erase switch circuit 543 is a circuit that outputs a RAM erase signal SG2 for clearing backup data to the main controller 261 and the payout controller 311 when the reset button 543a is pressed. When the RAM erase signal SG2 is input when the pachinko machine 10 is turned on, the main controller 261 and the payout controller 311 clear the data in the respective backup areas 503a and 513a.

  Here, the display content of the 1st symbol display apparatus 42 is demonstrated. As shown in FIG. 6, the first symbol display device 42 is provided with a special symbol display unit 42b for displaying a special symbol at the lower end of the display screen. Is provided with a decorative symbol display section 42a for displaying decorative symbols that scroll from right to left. The special symbol display portion 42b displays three symbol rows, left, middle, and right, and the decorative symbol display portion 42a includes three symbol rows Z1 to Z3 in three display areas divided into an upper row, a middle row, and a lower row. Is displayed. Here, the special symbol displayed on the special symbol display unit 42b will be mainly described.

  The special symbol display section 42b displays six types of special symbols “O”, “△”, “☆”, “×”, “#”, “*”, and each of the three symbols, left, middle, and right In each of the divided oblong display areas, a symbol string that is repeatedly displayed in the order of “O”, “Δ”, “☆”, “×”, “#”, “*”, and “O” is configured. The variation display of the special symbol is started based on a winning at the start port 33 (see FIG. 2), and the variation display of the three special symbols is stopped simultaneously after a certain time. After the stop, if any of the symbols “○”, “△”, “☆”, “×”, “#”, and “*” stops together, it will be a big hit, and then a big hit video will be displayed. On the other hand, if there are not three special symbols when the variable display is stopped, it will be lost, and the variable display will be performed again based on the winning at the start port 33.

  Next, the operation of the pachinko machine 10 configured as described above will be described. In the present embodiment, the MPU 501 in the main control device 261 uses various counter information during the game to perform jackpot lottery, setting of symbol display of the first symbol display device 42, and the like. Specifically, As shown in FIG. 7, when the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for selection of the jackpot symbol of the first symbol display device 42, and the first symbol display device 42 fluctuate and change. Reach random number counter C3 used for reach lottery, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, variation type counter CS for determining the type used for variation pattern selection, and special symbol display section 42b, left, middle and right out symbol counters CL used for setting each out symbol of the left symbol row, middle symbol row and right symbol row, M, and a CR.

  Here, the variation pattern means each pattern (form) in a case where features having common features of variation display are divided.

  Each of the counters C1 to C3, CINI, and CS is a loop counter that adds 1 to the previous value every time it is updated and returns to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using the R register (refresh register) in the MPU 501, and as a result, the numerical values change randomly. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). In each of these areas, a game ball to the start port 33 is provided. The values of the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are stored in accordance with the winning timing.

  Next, the specific contents of each counter will be described in detail.

  The jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is configured as a loop counter that is updated in the same range as the jackpot random number counter C1 (value = 0 to 676), and is updated once per timer interrupt and within the remaining time of normal processing. Will be updated repeatedly. The jackpot random number counter C1 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the start port 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”. The high probability means that a special symbol combination is a big win by a combination of predetermined probability variation symbols (in this embodiment, “◯” symbol) and the subsequent jackpot probability is increased as an added value. The time of so-called probability change is said, and the normal time (low probability) is the time when it is not such a probability change state.

  The jackpot symbol counter C2 determines symbols at the time of change stop in the special symbol display unit 42b of the first symbol display device 42 in the case of a jackpot, and in this embodiment, six types of special symbols are set. Therefore, six (0 to 5) counter values are prepared. That is, the jackpot symbol counter C2 is configured so that 1 is added in order within the range of 0 to 5, and after reaching the maximum value (that is, 5), it returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the start port 33. In this embodiment, the special symbol displayed at the time of the jackpot is a symbol symbol, and the decorative symbol is a numeric symbol, but the special symbol is also a numeric symbol and the same as the decorative symbol. You may make it set to a number. Also, in this embodiment, when the special symbol displayed at the time of the jackpot is “○” (when the decorative symbol is an odd number), it becomes a certain change until the next jackpot occurs, and the special symbol is other than “○”. At the time of (when the number is an even number in the decorative pattern), the normal state is not changed until the next jackpot occurs.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 11, for example, and reaches a maximum value (that is, 11) and then returns to 0. In the present embodiment, the reach random number counter C3 draws out “reach out” in which the final stop symbol stops without a big hit after the reach has occurred and “complete out” in which no reach occurs. For example, the reach random number counter C3 = 0 corresponds to outlier reach, and the reach random number counter C3 = 1 to 11 corresponds to complete outlier.

  Here, “reach” means that after the special symbol (or decorative symbol) displayed on the display screen of the first symbol display device 42 starts the variable display, the combination of symbols that stop first is the same symbol (a plurality of effective lines). In the case of a certain decorative symbol, it is the same symbol on any active line) and the jackpot condition is satisfied, suggesting to the player that it will be a jackpot depending on the display result of the symbol for which the variable display continues. This is a display that makes the player expect a combination of jackpot symbols and is a type of entertainment production. Interesting production means that a predetermined symbol represented by reach appears on the display screen of the first symbol display device 42 in the middle of variable display, a specific sound is output from a speaker, or a vibration motor This is an effect that causes the player to expect that the display result after the variable display will be a big hit with the variable display such as vibrating the game ball launching handle 18 by the variable display.

  The reach lottery may be set individually according to the state of the lottery probability of the first symbol display device 42, the number of suspended balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the start port 33.

  For example, the variation type counter CS is incremented by 1 in the range of 0 to 198, and after reaching the maximum value (that is, 198), it returns to 0. Depending on the fluctuation type counter CS, short reach (fluctuation time from fluctuation start to fluctuation stop is 15 seconds to 16 seconds), middle reach (fluctuation time is 20 seconds to 22 seconds), or long reach (fluctuation time is 30 seconds). The reach type of the special symbol is determined. Which reach is made corresponding to each of “0 to 198” constituting the value of the variation type counter CS is assigned in advance at different ratios for the big hit time and the outreach time. In the ROM 502 of the main controller 261, the value of the variation type counter CS and a command corresponding to each reach type (or each variation time) are stored in association with each other in advance. Here, it is not always necessary to determine the reach type by providing only one variation type counter CS, and the reach type may be determined using two or more variation type counters CS.

The counter CS is updated once every time a normal process to be described later is executed once, and is repeatedly updated even within the remaining time in the normal process. Then, the buffer value of the counter CS is obtained when the first symbol display device 42 determines the variation pattern at the start of variation of the decorative symbol and the special symbol.
The first to third off symbol counters CL, CM, and CR used for each of the left, middle, and right symbol rows stop stopping the left symbol row, middle symbol row, and right symbol row when the jackpot lottery is missed. It is for determining a design. Each symbol row displays one of six types of special symbols “○”, “△”, “☆”, “×”, “#”, “*”, and therefore, six symbols (0 corresponding to each symbol row) (0 Counter values 5 to 5) are prepared. A special symbol of “O” corresponds to a counter value of 0, “△” for a counter value of 1, “☆” for a counter value of 2, and so on for one counter value. Each special symbol corresponds. The symbol of the left symbol row is determined by the first symbol symbol counter CL, the symbol of the middle symbol symbol is determined by the second symbol counter CM, and the symbol of the right symbol column is determined by the third symbol counter CR.

  In the present embodiment, the values of the counters CL, CM, and CR are randomly updated by using the numerical value of the R register built in the MPU 501. That is, when each outlier symbol counter CL, CM, CR is updated, the lower 2 bits of the R register are added to the previous value, and when the addition result exceeds the maximum value, “6” is subtracted and the current value is obtained. Is determined. The outlier symbol counters CL, CM, CR are updated in the normal process so that the update times do not overlap, and the combination of these outlier symbol counters CL, CM, CR is the outlier symbol buffer B7 and the completely outlier symbol buffer in the RAM 503. Stored in any of B8. Then, when determining the variation pattern at the time of starting the variation of the special symbol, the buffer value of either the outreach symbol buffer B7 or the completely out symbol symbol buffer B8 is acquired according to the value of the reach random number counter C3.

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, it is desirable that the sizes of the jackpot random number counter C1 and the reach random number counter C3 variation type counter CS are different prime numbers and are not synchronized in any case.

  Next, each control process executed by the MPU 501 in the main controller 261 will be described with reference to the flowcharts of FIGS. The MPU 501 is roughly divided into a main process that is started when the power is turned on, and a timer interrupt process that is started periodically (in this embodiment, at a cycle of 2 milliseconds (hereinafter referred to as “ms”)). And an NMI interrupt process activated by the input of the power failure signal SG1 to the NMI terminal. For convenience of explanation, the timer interrupt process and the NMI interrupt process will be described first, and then the main process will be described.

  FIG. 13 is a flowchart showing the timer interrupt process. The timer interrupt process is executed by the MPU 501 of the main controller 261 every 2 ms, for example. In the timer interruption process, first, reading process of various winning switches is executed (S601). That is, the state of various switches (excluding the reset button 543a) connected to the main control device 261 is read, and the state of the switch is determined and the detection information (winning detection information) is stored. Next, the random number initial value counter CINI is updated (S602). Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area B4 of the RAM 503.

  Further, the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 are updated (S603). Specifically, the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are each incremented by 1 and their counter values have reached the maximum values (in the present embodiment, 676, 5, and 11 respectively). Each time it is cleared to 0. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer areas B1 to B3 of the RAM 503. Thereafter, a start winning process is performed in accordance with winning in the start port 33 (S604).

  This start winning process will be described with reference to the flowchart of FIG. First, it is determined whether or not the game ball has won the start opening 33 (start winning prize) based on the detection information of the operation opening switch (S701). If it is determined that the game ball has won the start opening 33 (S701: Yes), it is determined whether or not the number N of actuated balls of the first symbol display device 42 is less than the upper limit value (4 in the present embodiment). A determination is made (S702). If there is a prize at the start port 33 and the number of balls with an operating reserve N <4 (S702: Yes), the number of operating reserve balls N is incremented by 1 (S703), and the jackpot random number counter updated at the step S703 is further added. The values of C1, jackpot symbol counter C2 and reach random number counter C3 are stored in the first of the free reserved areas in the reserved ball storage area 700 of the RAM 503 (S704). On the other hand, if there is no winning at the starting port 33 (S701: No), or even if there is a winning at the starting port 33, if the number of suspended balls N <4 is not satisfied (S702: No), each of S703 and S704 The process is skipped and the start winning process is terminated. After the start winning process is completed, the MPU 501 once ends this timer interrupt process.

  When the game ball wins the start opening 33 (start winning), the special symbol display on the special symbol display unit 42b of the first symbol main display device 42 starts accordingly. There is a restriction that a predetermined time (for example, 5 seconds) must elapse before the special symbol changes and the symbol stops after winning. Therefore, in the start winning process, when a start winning is confirmed, a timer for measuring the elapsed time after the start winning is set after each counter value storing process (S704). Specifically, since the start winning process is executed in a cycle of 2 ms, for example, in order to measure an elapsed time of 5 seconds, a numerical value “2500” is set in the timer, and the timer value is incremented by 1 for each start winning process. Subtract. This timer value is stored and managed in the reserved ball storage area of the RAM 503 together with the values of the respective counters C1 to C3. When setting a special symbol variation pattern, which will be described later, the timer value is referred to, and a variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time elapses).

  FIG. 15 is a flowchart showing the NMI interrupt process. The NMI interrupt process is executed by the MPU 501 of the main control device 261 when the power of the pachinko machine 10 is shut down due to the occurrence of a power failure or the like. By this NMI interruption process, the state of the main controller 261 at the time of power-off is stored in the backup area 503a of the RAM 503. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure, the power failure signal 1 is output from the power failure monitoring circuit 542 to the NMI terminal of the MPU 501 in the main controller 261, and the MPU 501 interrupts the control being executed. NMI interrupt processing is started. The NMI interrupt processing program in FIG. 16 is stored in the ROM 502 of the main controller 261. For a predetermined time after the power failure signal is output, power is supplied from the power supply unit so that the processing of the main control device 261 can be executed, and the NMI interrupt processing is executed within this predetermined time.

  In the NMI interrupt process, first, the used register is saved in the backup area 503a of the RAM 503 (S801), and the value of the stack pointer is stored in the backup area 503a (S802). Further, the occurrence information of the power shutdown is set in the backup area 503a (S803), and a power shutdown notification command indicating that the power is shut off is transmitted to another control device (S804). A RAM determination value is calculated and stored in the backup area 503a (S805). The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. Thereafter, access to the RAM 503 is prohibited (S806), and the infinite loop is continued until the power supply is completely shut down and processing cannot be executed.

  The above NMI interrupt process is executed in the same manner in the payout control apparatus 311. With this NMI interrupt process, the state of the payout control apparatus 311 when the power is cut off due to the occurrence of a power failure or the like is stored in the backup area 513a of the RAM 513. Is done. Similarly, the power is supplied from the power supply unit so that the processing of the payout control device 311 can be executed for a predetermined time after the power failure signal SG1 is output. That is, when the power supply of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the MPU in the payout control device 311 and the MPU interrupts the control being executed. The NMI interrupt process of FIG. 15 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 8 is a flowchart showing a main process executed by the MPU 501 in the main controller 261. This main process is started by a reset at power-on. In the main process, first, an initial setting process associated with power-on is executed (S101). Specifically, in order to set a predetermined value in the stack pointer and wait for the sub-side control devices (sound / lamp control device 262, payout control device 311, etc.) to become operable. , Wait processing (for example, about 1 second) is executed. After a payout permission command is transmitted to the payout control device 311 (S102), access to the RAM 503 is permitted (S103).

  Thereafter, it is determined whether or not the RAM erase switch provided in the power supply device is turned on (S104), and if it is turned on (S104: Yes), the process proceeds to S114 to clear (erase) the backup data. Transition. On the other hand, if the RAM erasure switch is not turned on (S104: No), it is further determined whether or not the power interruption occurrence information is stored in the backup area 503a of the RAM 503 (S105), and if not stored (S105). : No), since backup data is not stored, in this case as well, the process proceeds to S114. If the occurrence information of power shutdown is stored in the backup area 503a (S105: Yes), the RAM judgment value is calculated (S106), and the calculated RAM judgment value is not normal (S107: No), that is, calculated. If the RAM determination value does not match the RAM determination value stored at the time of power-off, the backed up data has been destroyed. Even in such a case, the process proceeds to S114. As described above, the RAM determination value is a checksum value at a work area address of the RAM 503, for example. Instead of the RAM determination value, the validity of the backup may be determined based on whether or not the keyword written in a predetermined area of the RAM 503 is correctly stored.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in a hall, the power is turned on while pressing the RAM erase switch. Therefore, if the RAM erase switch has been pressed, the routine proceeds to RAM initialization processing (S114 to S116). Similarly, when the information on occurrence of power shutdown is not set or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing (S114 to S116) of the RAM 503 in the same manner. That is, in the RAM initialization process from S114, the used area of the RAM 503 is cleared to 0 (S114), and the initial value of the RAM 503 is set (S115). Thereafter, the interrupt is permitted (S116), and the process proceeds to normal processing described later.

  On the other hand, if the RAM erasure switch is not turned on (S104: No), the occurrence information of the power shutdown is stored (S105: Yes), and if the RAM judgment value (checksum value etc.) is normal (S107) : Yes), the process proceeds to S108, and the process at the time of power recovery (process at the time of power-off recovery) is executed. That is, in the power recovery process, the stack pointer at the time of power interruption is restored (S108), and the information on occurrence of power interruption is cleared (S109). Next, a power-return command for returning the sub-side control device to the gaming state at the time of power-off is transmitted (S110), and the used register is returned from the backup area 503a of the RAM 503 (S111). Further, it is confirmed whether or not the interrupt is permitted before the power is turned off (S112). If the interrupt is permitted (S112: Yes), the interrupt is permitted (S113), while the interrupt is prohibited when the power is turned off. If it is in the state (S112: No), the processing is returned to the address before the power is shut off while the interruption is prohibited.

  Next, normal processing will be described with reference to the flowchart of FIG. In this normal process, the main process of the game is executed. As an outline, each process of S201 to S207 is executed as a periodic process with a period of 4 ms, and the counter update process of S208 to S210 is executed in the remaining time.

  In the normal processing, first, output data such as a command updated in the previous processing is transmitted to each control device on the sub side (S201). Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. In addition, a stop symbol command, a variation pattern command, a confirmation command, and the like are transmitted to the display control device 45 when the first symbol main display device 42 displays the variation of the special symbol. In addition, at the time of starting the change of the special symbol, one each time in the normal process in the order of the change pattern command-> stop symbol command of the left symbol row-> stop symbol command of the middle symbol row-> stop symbol command of the right symbol row (i.e. The command is transmitted once every 4 ms), and the confirmation command is transmitted at the end of the fluctuation time.

  Next, each value of the variation type counter CS is updated (S202). Specifically, the variation type counter CS is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (198 in the present embodiment). Then, the update value of the variation type counter CS is stored in the corresponding buffer area of the RAM 503. Further, the off symbol counters CL, CM, and CR of the left symbol row, the middle symbol row, and the right symbol row are updated by the miss symbol counter updating process (S203).

  Here, the off symbol counter updating process will be described with reference to FIG. First, it is determined whether or not it is the update time of the first out symbol counter CL corresponding to the left symbol row (S301). If it is the update time (S301: Yes), the first out symbol counter CL is updated (S303). . Next, if it is not the update time of the left symbol row (S301: No), it is determined whether or not it is the update time of the second out symbol counter CM corresponding to the middle symbol row (S302), and if it is the update time (S302). : Yes), the second off symbol counter CM is updated (S304). Further, if it is not the update time of the middle symbol row (S302: No), it is the update timing of the right symbol row, so the third off symbol counter CR corresponding to the right symbol row is updated (S305).

  In updating outlier symbol counters CL, CM, and CR in each of the processes of S303 to S305, the value of the lower 2 bits of the R register is added to the previous counter value, and 3 is added when the addition result exceeds the maximum value. Subtraction is performed, and the result of the calculation is taken as the current value of the symbol counters CL, CM, CR. According to the update process of CL, CM, CR, the outlier counters CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row are sequentially updated one by one in one normal process. The update time of each counter value does not overlap. As a result, every time the normal process is executed three times, one set of the off symbol counters CL, CM, CR is updated.

  Thereafter, it is determined whether or not the combination of the updated outlier symbol counters CL, CM, and CR is a jackpot symbol combination (S306). If the symbol combination is a jackpot symbol combination (S306: Yes), this processing is performed as it is. finish. If it is not a jackpot symbol combination (S306: No), it is determined whether or not it is a reach symbol combination (S307), and if it is a reach symbol combination (S307: Yes), the off symbol counter CL at that time, The combination of CM and CR is stored in the outreach symbol buffer B9 of the RAM 503 (S308). If the combination of the out symbol counters CL, CM, CR is not a jackpot symbol combination (S306: No) and is not a reach symbol combination (S307: No), the combination of the out symbol counters CL, CM, CR is out of reach. In such a case, the combination of the off symbol counters CL, CM, CR is stored in the complete off symbol buffer B10 of the RAM 503 (S309).

  After the end of the off symbol counter CL, CM, CR update processing (S203), the process returns to the normal processing of FIG. 9 and reads the award ball count signal and the payout abnormality signal received from the payout control device 311 (S204). A special symbol variation process for performing variation display of the special symbol by the symbol display device 42 is executed (S205). With this special symbol variation processing, jackpot determination, special symbol variation pattern setting, and the like are performed. Details of the special symbol variation process will be described later with reference to FIG.

  After the special symbol variation process is completed, a special prize opening / closing process for opening or closing the special prize opening of the variable prize winning device 32 is executed in the case of the big win state (S206). That is, the big winning opening is opened for each round of the big hit state, and it is determined whether the maximum opening time of the big winning opening has elapsed or whether a predetermined number of game balls have been won in the big winning opening. When either of these conditions is satisfied, the special winning opening is closed. At this time, the continuous winning opening is allowed on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  Thereafter, it is determined whether or not the next normal process execution timing has been reached, that is, whether or not a predetermined time (4 ms in the present embodiment) has elapsed since the start of the previous normal process (S207). If (S207: Yes), the process proceeds to S201, and the processes after S201 described above are repeatedly executed.

  On the other hand, if the predetermined time has not yet elapsed from the start of the previous normal process (S207: No), the random number initial value is within the remaining time until the predetermined time is reached, that is, until the next normal process is executed. The value counter CINI and the variation type counter CS are updated repeatedly (S208, S209). First, the random number initial value counter CINI is updated (S208). Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. Next, the counter CS is updated (S209). Specifically, the counter CS is incremented by 1 and cleared to 0 when the counter values reach the maximum value. Then, the updated value of the counter CS is stored in the variation type counter buffer B6 of the RAM 503.

  Here, since the execution time of each process of S201 to S206 changes according to the state of the game, the remaining time until the execution timing of the next normal process is not constant and varies. Therefore, it is possible to update the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. The counter CS can also be updated at random.

  Next, the special symbol variation process (S205) will be described with reference to the flowcharts of FIGS. In the special symbol variation process, first, it is determined whether or not a big hit is currently being made (S401). The jackpot includes the jackpot game displayed on the first symbol display device 42 in the jackpot and the middle of a predetermined time after the jackpot game ends. As a result of the determination, if it is a big hit (S401: Yes), this processing is terminated as it is.

  If it is not a big hit (S401: No), it is determined whether or not the special symbol variation display is being performed by the first symbol main display device 42 (S402), and if the special symbol variation display is not being performed (S402: No). ), It is determined whether or not the number N of actuated balls of the first symbol display device 42 is greater than 0 (S403). If the number N of active suspension balls is 0 (S403: No), this process is ended as it is. If the number of the operation holding balls N> 0 (S403: Yes), the operation holding ball number N is decremented by 1 (S404), and the data stored in the holding ball storage area is shifted (S405). This data shift process is a process of sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side, and the reserved first area → execution area, reserved second area → Specifically, the data in each area is shifted, such as the hold first area, the hold third area → the hold second area, and the hold fourth area → the hold third area. After the data shift process, a special symbol variation start process is executed (S406). The variation start process will be described later with reference to FIG.

  In the process of S402, when the variation display of the special symbol is being performed (S402: Yes), it is determined whether or not the variation time has elapsed (S407). The variation time of the special symbol is determined according to the variation pattern of the special symbol, and the execution of the process of S408 is skipped until the variation time elapses (S407: No). On the other hand, if the variation time of the special symbol elapses (S407: Yes), a confirmation command set for confirming the stop symbol is set (S408), and this process is terminated.

  Next, the variation start process will be described with reference to the flowchart of FIG. In the fluctuation start process (S406), first, it is determined whether or not a big hit is made based on the value of the big hit random number counter C1 stored in the execution area of the reserved ball storage area (S501). Whether or not the jackpot is determined is based on the relationship between the jackpot random number counter value and the mode at that time. As described above, “337,673” is a winning value among the numerical values 0 to 676 of the jackpot random number counter C1 at the normal low probability, and “67, 131, 199, 269, 337, 401, 463, 523” at the high probability. “601, 661” is the winning value.

  When it is determined that the game is a big hit (S501: Yes), the symbol corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, the jackpot symbol is the value of the jackpot symbol counter C2 and the symbol. The symbol is obtained based on a table (not shown) representing the corresponding relationship, and the symbol is set as a stop symbol command (S502). In the table, a stop symbol command indicating the display of a special symbol of “O” is assigned to the numerical value “0” of the jackpot symbol counter C2, and a command indicating “Δ” is assigned to “2”. "" For "3", "x" for "3", "#" for "4", and "5" for "5" Each command indicating “*” is assigned. In addition, when the jackpot symbol is aligned with a specific symbol (○), it shifts to the probability variation state, but when it is aligned with another specific symbol (non-probability variation symbol), it shifts to the probability variation state. do not do.

  Next, the variation pattern of the special symbol until it stops at the jackpot symbol is determined, and the variation pattern is set in the variation pattern command (S503). At this time, the value of the variation type counter CS stored in the counter buffer B6 of the RAM 503 is confirmed, and the reach type such as short reach, middle reach, long reach, and the variation time are determined based on the value. The relationship between the numerical value of the variation type counter CS1 and the reach pattern is defined in advance by a table or the like.

  If it is determined in step S501 that the game is not a big hit (S501: No), is the reach generated (occurrence of outreach) based on the value of the reach random number counter C3 stored in the execution area of the reserved ball storage area? It is determined whether or not (S504). In the present embodiment, the value of the reach random number counter C3 is any one of 0 to 11, of which “0” corresponds to occurrence of out of reach and “1 to 11” corresponds to no reach (complete out).

  In the case of occurrence of outreach (S504: Yes), the respective values of the left, middle and right outreach symbol counters CL, CM and CR stored in the outreach symbol buffer B7 of the RAM 503 are set as stop symbol commands (S505). ). Further, a variation pattern for displaying the outlier reach is determined, and the variation pattern is set in the variation pattern command (S506). At this time, similarly to the processing of S503, the value of the fluctuation type counter CS stored in the counter buffer B6 of the RAM 503 is confirmed, and the reach type such as short reach, middle reach, long reach, etc. is changed based on the value. Decide on time.

  If neither big hit nor reach (S501: No, S504: No), the left, middle, and right out symbol counters CL, CM, CR stored in the complete out symbol buffer B8 of the RAM 503 are stored. The stop symbol command is set (S507). Also, a variation pattern for complete out-of-range display is determined, and the variation pattern is set as a variation pattern command (S511). At this time, the variation pattern is determined based on the value of the variation type counter CS stored in the counter buffer B6 of the RAM 503, as in the processing of S503. As described above, when the setting of the symbol stop command and the variation pattern command is completed at the time of jackpot, when the reach occurs, or when the reach does not occur, this processing is terminated.

The variation pattern of complete detachment may be determined according to the value of the number N of activated balls at the start of variation. For example, the variation time of complete detachment started when the number N of activated balls is 3 or more. Further, it may be made shorter than the fluctuation time of complete deviation starting when the number N of the operation holding balls is less than 3. Suppressing useless start winnings by quickly digesting the fluctuation display while waiting, and preventing the fluctuation display from being interrupted, and preventing the player's willingness to diminish due to continued fluctuation stoppage. Can do.
Next, with reference to FIGS. 5 and 16 to 19, the special symbols and decorative symbols displayed on the first symbol main display device 42 will be described together with the control of the display control device 45.

  The first symbol main display device 42 has a decorative symbol display area 42a in which three symbol rows (decorative symbol symbol rows) Z1 to Z3 are displayed at the center thereof, and “◯” and “ A special symbol display area 42b on which six types of special symbols of “Δ”, “☆”, “×”, “#”, and “*” are displayed is provided.

  In the special symbol display area 42b, when the value of the jackpot random number counter C1 acquired at the time of winning the start opening 33 is a jackpot, the three symbols are stopped and the player is shown the occurrence of the jackpot. In the pachinko machine 10 of the present embodiment, two types of symbols, a special symbol and a decorative symbol, are provided as symbols for showing the player the occurrence of a jackpot. The special symbols are provided in order to reduce the types of symbols and reduce the types of commands of the main control device 261 and the display control device 45. On the other hand, the decorative symbol is a symbol that changes in synchronization with the special symbol, and starts to change at the same time (or almost at the same time) as the special symbol starts to change, and at the same time as the special symbol stops changing (or almost at the same time). At the same time) the fluctuation is stopped. This decorative design is provided in order to provide a player with a variety of display effects so that the player is not bored. By using these two types of symbols together, while the pachinko machine 10 has various effects, the number of commands transmitted from the main control device 261 to the display control device 45 is reduced and the control program of the main control device 261 is simplified. Or the use area of the storage device such as the ROM 502 and RAM 503 of the main controller 261 can be reduced.

  Note that it is not always necessary to separately provide a special symbol and a decorative symbol to control the display of the first symbol display device 42. Instead of the special symbol, the display content of the decorative symbol is directly determined by the control of the main controller 261. You may make it do. Further, it is not necessary to cause the display control device 45 to perform control so as to start or stop changing the decorative symbol simultaneously with the special symbol. If the change display of the special symbol and the change display of the decorative symbol are performed synchronously, that is, if the change display of each symbol is performed the same number of times based on the start winning prize, the change start of the decorative symbol and the special symbol is started. Or you may make the display control apparatus 45 perform display control so that at least one timing of a fluctuation stop may not correspond. For example, the variation of the decorative symbol may be started after the variation of the special symbol, or the variation of the decorative symbol may be stopped before the variation of the special symbol.

  Next, the decorative symbols displayed in the decorative symbol display area 42a will be described. In the decorative symbol display area 42a of the first symbol display device 42, as shown in FIG. 5, three symbol rows Z1 to Z3 of an upper stage, a middle stage, and a lower stage are displayed. As shown in FIG. 5, the decorative symbol is composed of, for example, a main symbol consisting of numbers “1” to “9” with characters and a sub symbol consisting of shells smaller than the main symbol. A symbol row of decorative symbols is formed by the symbols. In each symbol row formed with decorative symbols, the main symbols are arranged in ascending or descending order of numbers, and sub-designs are arranged between the main symbols.

  Next, with reference to FIGS. 16 to 19, the contents of the symbol control that is stopped and displayed on the decorative symbol display unit 42a will be described. The MPU 520 of the display control device 45 selects the display content of the decorative symbol based on the command transmitted from the main control device 261. FIG. 16 is a diagram schematically showing an outline of various counters provided in the RAM 523 of the display control device 45 and used for selection of a decorative symbol displayed on the decorative symbol display unit 42a.

  The first to third decorative symbol counters S1 to S3 are for determining the decorative symbol to be displayed in each symbol row. When the fluctuation of each of the symbol rows Z1 to Z3 shown in FIG. 18 is stopped, any one of the decorative symbols corresponding to the number of frames is displayed. Therefore, each of the symbol rows Z1 and Z3 has 18 symbols (0 to 117), For the column Z2, 20 (0 to 19) counter values are prepared. The stop symbol of the symbol row Z1 is determined by the first decorative symbol counter S1, the stop symbol of the symbol row Z2 is determined by the second decorative symbol counter S2, and the stop symbol of the symbol row Z3 is determined by the third decorative symbol counter S3. .

  In this embodiment, the values of the counters S1 to S3 are randomly updated by using the numerical value of the R register built in the MPU 521. That is, when each of the decorative symbol counters S1 to S3 is updated, the value of the lower 3 bits (that is, “0 to 7”) of the R register is added to the previous value, and each maximum value is obtained when the addition result exceeds the maximum value. The current value is determined by subtraction. Each of the decorative symbol counters S1 to S3 is updated in the normal process so that the update times do not overlap, and the combination of the decorative symbol counters S1 to S3 is a jackpot symbol buffer B20, a reach symbol buffer B21, and a completely missed symbol buffer in the RAM 523. Stored in any of B22. Then, when a variation pattern command indicating the variation start of the special symbol is received, the buffer value of any one of the jackpot symbol buffer B20, the reach symbol buffer B21, and the completely off symbol buffer B22 is acquired according to the content of the command.

  Next, each process executed by the MPU 521 of the display control device 45 will be described with reference to FIGS. FIG. 17 is a flowchart showing a main process of the display control device 45, and this main process is started by a reset at power-on.

  The main process of the display control device 45 first executes an initial setting process upon power-on (S811), initializes values of RAM, I / O, etc., and sets each interrupt, such as a timer interrupt. Do. Thereafter, the processing from S812 to S815 is repeatedly executed every 4 ms to control the display content of the first symbol main display device.

  First, an external output process is performed in which a voice output command is transmitted to the voice / lamp control device 262 in order to output a voice in accordance with the display contents of the display devices 41 and 42 (S812). Update of S1 to S5 is performed (S813).

  Here, with reference to FIG. 18, a decoration symbol counter update process (S813) is demonstrated. FIG. 18 is a flowchart showing a decoration symbol counter update process (S813) executed in the main process of FIG.

  First, it is determined whether the decoration symbol counter of the symbol row is to be updated, and counter update processing (S821) is performed to update the decoration symbol counter of the symbol row that has reached the update timing in accordance with the update timing. Specifically, it is determined whether or not it is the update time of the decorative symbol counter S1 of the left symbol row Z1, and if it is the update time, the decorative symbol counter S1 of the first symbol row Z1 is updated. On the other hand, if it is not the update time of the first symbol row Z1, it is determined whether or not it is the update time of the decorative symbol counter S2 of the second symbol row Z2, and if it is the update time, the decorative symbol counter S2 of the second symbol row Z2 is set. Update. Similarly, it is determined whether or not it is the update time of the third symbol row Z3. If it is the update time, the decorative symbol counter S2 of the second symbol row Z2 is updated, and the counter update process (S821) is ended.

  In the update of the decorative symbol counters S1 to S3 in the process of S821, the value of the lower 3 bits of the R register is added to the previous counter value, and when the addition result exceeds the maximum value, the maximum value is subtracted. The calculation result is set as the current value of the decorative symbol counters S1 to S3. According to the update processing of S1 to S3, each of the decorative symbol counters S1 to S3 of the first to third symbol rows Z1 to Z3 is sequentially updated one by one in one normal processing, so that each counter value is updated. The times do not overlap. Thereby, every time the normal process is executed three times, one set of the decorative symbol counters S1 to S3 is updated.

  Thereafter, it is determined whether or not the combination of the updated decorative symbol counters S1 to S3 is a jackpot symbol combination (S826). If it is a jackpot symbol combination (S826: Yes), the decorative symbol counter at that time is determined. The combination of S1 to S3 is stored in the jackpot symbol buffer B20 of the RAM 523 (S828), and this process ends. As the determination of the jackpot symbol combination, all the combinations of counter values for which the jackpot symbol combination is formed on any of the effective lines set in the three symbol columns are stored in the ROM 522 of the display control device 45 in advance. , By comparing with its value.

  If it is not a jackpot symbol combination in the process of S826 (S826: No), it is determined whether or not it is a reach symbol combination (S827), and if it is a reach symbol combination (S827: Yes), the decoration at that time The combination of the symbol counters S1 to S3 is stored in the reach symbol buffer B21 of the RAM 523 (S829). If the combination of the decorative symbol counters S1 to S3 is not a jackpot symbol combination (S826: No), and is not a reach symbol combination (S827: No), the combination of the decorative symbol counters S1 to S3 is a completely out-of-band combination (reach) In such a case, the combination of the decorative symbol counters S1 to S3 is stored in the completely out of symbol buffer B22 of the RAM 523 (S830). Here, the combination of reach symbols and the combination of complete deviation may differ depending on the variation patterns of normal stop fluctuation, forward stop fluctuation, and pinch stop fluctuation, but a corresponding symbol buffer is provided for each fluctuation pattern. Thus, a combination of symbols corresponding to each variation pattern may be described.

  After completion of the decorative symbol counters S1 to S3 update processing (S813), the decorative symbol display processing for returning to the main processing of FIG. 17 and advancing the decorative symbol display on the decorative symbol display unit 42a of the first symbol main display device 42 is performed. (S814). Thereafter, a special symbol display process is performed to advance the special symbol variation display in the special symbol display unit 42b (S815). The display control in S814 and S815 is performed according to the contents of the effect execution area 701 shown in FIG. 16 set based on the command received from the main control device 261.

  Next, the elapsed time from the start of the previous processing of S812 is confirmed (S816). If the elapsed time is less than 4 ms in the process of S816 (S816: No), the process of S816 is repeated until 4 ms elapses. When it is confirmed that 4 ms has elapsed in the process of S816 (S816: Yes), the process proceeds to S812, and the subsequent process is executed.

  By proceeding with the process based on the elapsed time from the process of S812 in the process of S816, the process of S812 to S815 can be performed every 4 ms, and the decorative symbol counters S1 to S3 are updated every 4 ms. Can do. Note that it is not always necessary to provide counters for determining the combination of decorative symbols for the number of symbol columns. Counters are provided for only one central symbol sequence, and others may be fixedly displayed according to predetermined combinations. good. Further, a table in which a plurality of reach variation patterns are set in advance may be stored in the display control device 45, and the variation pattern may be derived from the table.

  Next, a command reception process performed by the display control device 45 will be described with reference to FIG. FIG. 19 is a flowchart of command reception processing of the display control device 45. This command reception process is an interrupt process executed when a command is received from the main control apparatus 261 in the display control apparatus 45, and a process associated in advance with the command transmitted from the main control apparatus 261 by this process. Is performed by the display control device 45.

  In the command reception process, the received command is confirmed (S841), and if the command is a variation pattern command (S841: variation pattern command), the variation pattern command is written in the effect execution area (S842). Corresponding to this variation pattern command, variation patterns such as variation time and presence / absence of reach in a special symbol are determined in advance, and variation displays corresponding to various lotteries performed by the MPU 502 of the main controller 261 are the first symbol. This is performed by the display device 42.

  Next, the content of the received variation pattern command is confirmed (S843), and if it is a jackpot variation pattern command (S843: jackpot), the value of the jackpot symbol counter buffer B20 is used as a stop symbol of the decoration symbol for the current variation display. Write and store (S844). If the command received in the process of S843 is a reach command (S843: reach), the value of the reach symbol buffer B21 corresponding to the variation pattern is written in the effect execution area 701 (S845). If the received command is completely out of order (S843: complete out), the value of the complete out symbol buffer B22 corresponding to the variation pattern is written in the effect execution area 701 (S846). By setting the value of the symbol buffer corresponding to the variation pattern command as a stop symbol of the decoration symbol for the current variation display by the processing of S844 to S846, both the special symbol and the decoration symbol are big hits, either reach or completely missed Can be stopped.

  Thereafter, a lamp turn-off command for turning off one hold lamp 46 is transmitted to the voice / lamp control device 262 (S847). In the process of S847, the lamp turn-off command is once written in the command transmission area (transmission buffer) provided in the RAM 523, and the lamp turn-off command is transmitted by the external output process (S812) described above. After the processing of S847, the first symbol display device 42 starts the variable display of the special symbol and the decorative symbol (S848), and the command reception processing is terminated.

  If the command received in the process of S841 is a stop symbol command (S841: stop symbol command), the stop symbol data is written in the effect execution area 701 (S849), and the command reception process is terminated. If the received command is a confirmed command (S841: confirmed command), the variable display is confirmed and stopped (S850), and the command receiving process is terminated. If the command received in the process of S841 is not any of the variation pattern command, the stop symbol command, and the confirmed command (S841: other command), each process according to the received command is executed (S851). ), The command reception process is terminated.

  As described above, in the display control device 45, when the variation pattern command is received from the main control device 261, the value of the symbol buffer corresponding to the variation pattern command is stopped for the current variation display by the processing of S843 to S846. Set as a symbol. Thus, both the special symbol and the decorative symbol can be stopped by either a big win, reach or completely off in accordance with the lottery result performed by the main controller 261, and the big win and reach lottery of the main controller 261 can be stopped. It is possible to execute a variation display of the decorative pattern corresponding to the result.

  Next, the structure when the front frame set 14 (corresponding to a glass frame) is opened, which is the main feature of the present invention, will be described.

  FIG. 20 is a diagram illustrating a connection state between the main control board (also referred to as a main control device) 261 and the open detection switch SW1. In the present embodiment, as shown in FIG. 20, the open detection switch SW1 is electrically connected to the main control board 261, and the main control board 261 constantly monitors the open state during the main flow process. It has become. More specifically, the output terminal of the open detection switch SW1 is connected to one input port P1 of the input / output ports 505 of the main control board 261 via the signal line m1, and the input port P1 The MPU 501 of the main control board 261 determines the change of the logic level every certain period (for example, several msec) during the main flow process. This input port P1 is at a low level in a normal state (a state where the front frame set 14 is closed) according to an output of the open detection switch SW1, and is open (a state where the front frame set 14 is opened). Changes to a high level. Thereby, the MPU 501 can determine the open state.

  When the logic level of the input port P1 becomes high level, the MPU 501 proceeds to the open state processing flow. This open state processing flow is in an infinite loop state until the output of the open detection switch SW1 becomes low level. In this open state process flow, only a process of transmitting a predetermined control command related to the open state and a process of transmitting a drive control command to the payout control device 311 are performed. Here, the predetermined control commands related to the release state are an release command indicating that the release is being performed, a standby command indicating that the release is being performed, a stop symbol determination command, and the like.

Next, the control operation of the gaming machine in the open state will be described. FIG. 21 is a timing chart showing the operation in the open state. Note that FIG. 21 assumes a case where a ball clogging occurs in the variable display. When the game ball stops on the game board and the store clerk in the game hall opens the front frame set 14 (corresponding to a glass frame), the operation part 600 of the open detection switch SW1 protrudes, and the output of the open detection switch SW1 is thereby output at time t2. It changes to a high level (see FIG. 21 (2)).
As a result, the main control board 261 shifts from the main flow process to the open state process flow as described above, so that the gaming state is temporarily stopped (see FIG. 21 (8)). Accordingly, processing relating to the progress of the game, such as detection of a prize opening switch, is not performed. As a result, even if the ball is clogged in the big hit state and the front frame set 14 is opened, the gaming state is temporarily stopped, so there is no disadvantage to the player.

  Further, at this time t1, the main control board 261 transmits an open command to the display control board (also referred to as a display control device) 45 (see FIG. 21 (2)). Upon receiving the release command, the display control board 45 interrupts the formation of the variable display image at this time t2, forms a release display image (for example, an “open” image), and outputs it to the first symbol display device 42. To do. As a result, the “open” image shown in FIG. 22A is displayed on the first symbol display device 42. At the same time, an open command is transmitted to the voice / lamp control board (also called voice / lamp control device) 262. Thereby, the sound / lamp control board 262 drives the sound / lamp so as to notify the open state. That is, from time t2, a sound output “currently open” is output from the speaker, and all the lamps are blinked (see FIG. 21 (7)). As described above, the first symbol display device 42, the speaker, and the lamp notify that the gaming machine is being opened. Therefore, even if an attempt is made to illegally enter the gaming ball by opening the front frame set 14, As a result, it is possible to effectively prevent such illegal acts.

  Note that if the store clerk removes the game ball that has stopped on the game board and, for example, puts the game ball as a service into the big prize opening, the payout device is not stopped and is in an operable state (FIG. 21 (9)). A predetermined number of game balls are paid out.

  Thereafter, when the store clerk closes the front frame set 14, the operation unit 600 is pushed in, and the output of the open detection switch SW1 becomes low level (see FIG. 21 (2)). When detecting this at time t3, the main control board 261 transmits a standby command to the display control board 45 (see FIG. 21 (4)). Upon reception of the standby command, the display control board 45 interrupts the formation of the open display image at this time t3, forms a standby display image (for example, a “standby” image), and displays it on the first symbol display device 42. Output. Accordingly, the “standby” image shown in FIG. 22B is displayed on the first symbol display device 42. At the same time, a standby command is transmitted to the voice / lamp control board 262. Thereby, the sound / lamp control board 262 drives the sound / lamp so as to notify the standby state. At this time, the sound from the speaker and the lighting state of the lamp are different from the open state. Note that the voice / lamp drive may be stopped during standby.

When the fluctuation period ends t4, the main control board 261 transmits a confirmation command (see FIG. 21 (5)). Then, the main control board 261 returns to the main flow, and the stop of the gaming state is released. When receiving the confirmation command, the display control board 45 displays the stop symbol that was scheduled to be displayed at the time t4 when the variable display ends.
In the above example, a case where a ball clogging occurs during the variable display has been described. However, the same is basically true even during the big hit state, and the gaming state is temporarily stopped.

  In this way, even if a ball clog occurs and the front frame set 14 is released, the gaming state is temporarily stopped, so even if a ball clog occurs during the big hit state, the gaming state does not proceed. It is eliminated that the player is disadvantaged as in the conventional example.

  In the demo screen, “Open” is displayed during the release as well as during the above change, and when it is closed, it returns to the demo screen after a few seconds and the game stop state is released. Yes.

[Second form]
In the first embodiment, the opening detection switch SW1 is connected to the main control board 261. However, in the second embodiment, the opening detection switch SW1 is connected to the power supply board 261. A similar process (pseudo power failure process) is performed.

  FIG. 23 is a diagram showing a connection state between the open detection switch SW1 and the power supply board 313 in the second embodiment. In FIG. 23, reference numeral 660 denotes a main control board case for sealing the main control board 261. The open detection switch SW1 is connected to the power failure monitoring circuit 542 of the power supply board 313, and an open signal (high level signal) is provided to the power failure monitoring circuit 542 when the front frame set 14 is opened. Thereby, the power failure monitoring circuit 542 provides the power failure signal SG1 to the NMI terminal of the main control board 261 in the same manner as at the time of a power failure. As a result, the main control board 261 executes the NMI interrupt process shown in FIG. A specific description of the NMI interrupt processing has already been made in the description of FIG.

  When the front frame set 14 is closed, the output state of the open detection switch SW1 changes. Thereby, the power failure monitoring circuit 542 outputs a return signal from a line (not shown) to the main control board 261. When this return signal is input to the main control board 261, the main control board 261 returns to the gaming state immediately before the start of the pseudo power failure process. Therefore, also in the second embodiment, even if the ball clogging occurs during the big hit state and the front frame set 14 is released, the gaming state does not proceed, so that the player is disadvantaged as in the conventional example. Receiving is canceled. Furthermore, since it is a pseudo power failure state during the open state, it is possible to prevent an illegal act such as stealing the eyes of a store clerk and winning a game ball in an accessory.

  In the second mode, it is only necessary that the open detection switch SW1 and the power supply board 261 are connected. As shown in FIG. 24, the power failure state notification for notifying the power / lamp control board 262 of the power failure state is sent from the main control board 261. It may be configured to provide a signal.

  The gaming machine having the configuration shown in FIG. 24 is improved in order to prevent an illegal act occurring in the gaming machine having the configuration shown in FIG. That is, as shown in FIG. 25, a power failure signal line connecting the power failure monitoring circuit 542 and the main control board 261 is electrically connected to a board called a hanging board 665, and the power failure signal SG1 is sent from there for a short time. If the jackpot random number counter C1 of the main control board 261 is initialized by transmitting a number of times, winning can be performed when the jackpot random number is reached, and the jackpot state is obtained illegally. In order to prevent such an illegal act, a power failure state notification signal is given from the main control board 261 to the sound / lamp control board 262 so that the speaker and the lamp always notify the power failure state at the time of a power failure. Since it can be immediately detected that 665 is connected, fraudulent acts can be effectively prevented. In the simulated power failure process, the power failure signal SG1 is output to the NMI terminal of the main control board 261 and the power failure signal is also output to the NMI terminal of the payout control board (also referred to as a payout control device) 311 as in the case of a normal power failure. SG1 may be output to stop the payout device 262, and the power failure monitoring circuit 542 may not output the power failure signal SG1 to the payout control board (also referred to as payout control device) 311.

[Third embodiment]
FIG. 26 is a diagram showing a connection state of the open detection switch SW1 of the third embodiment. The third embodiment is characterized in that the main control board 261 and the power supply board 313 are sealed by the main control board case 660, and the open detection switch SW1 and the power failure monitoring circuit 542 are connected by the optical fiber cable 703. It is. In the third embodiment, a pseudo power failure process is performed when the front frame set 14 is opened, as in the second embodiment.
In the board connection state of FIG. 24 shown in the second embodiment, if the hanging board 666 is connected to the power failure state notification signal line (see FIG. 27) and the power failure state notification signal is cut off, the jackpot state is obtained illegally. It becomes possible. Therefore, in the third embodiment, as shown in FIG. 26, the main control board 261 and the power supply board 313 are sealed by the main control board case 660 to prevent the hanging board 665 from being connected to the power failure signal line. is there. However, even with this configuration, if a hanging board is connected between the open detection switch SW1 and the power failure monitoring circuit 542, an incorrect jackpot state can be obtained.

  Therefore, in the third embodiment, in addition to sealing the main control board 261 and the power supply board 313 by the main control board case 660, a hanging board is connected between the open detection switch SW1 and the power failure monitoring circuit 542. In order to prevent this, the open detection switch SW1 and the power failure monitoring circuit 542 are connected by an optical fiber 703. The reset button 543a is exposed to the outside of the main control board case 660 and can be reset.

Next, a specific configuration will be described with reference to FIG.
The optical fiber cable 703 is configured by covering a quartz glass fiber cable or a plastic fiber cable with a light shielding material. A connector 700 is provided at one end of the optical fiber cable 703. The connector 700 is connected to an output terminal (not shown) of the open detection switch SW1, and the optical fiber cable 703 and the open detection switch SW1 are connected. The Further, a connector 701 is provided at the other end of the optical fiber cable 703. This connector 701 is connected to an input terminal of a power supply board 313 (more precisely, a power failure monitoring circuit 542), and the power supply board 313 and the open detection switch SW1. And are connected. Thereby, the power failure monitoring circuit 542 and the open detection switch SW1 are connected by the optical transmission line.

  The connector 700 of the optical fiber cable 703 incorporates an electrical signal / optical signal conversion unit 702 that converts an electrical signal into an optical signal. The electrical signal / optical signal conversion unit 702 is formed of, for example, a light emitting diode. On the other hand, the connector 701 of the optical fiber cable 703 does not incorporate an optical signal / electrical signal conversion unit that converts an optical signal into an electrical signal. Instead, an optical signal / electrical signal converter 704 is provided at the input of the power failure monitoring circuit 542. As described above, the optical signal / electrical signal conversion unit 704 is not provided in the connector 701 but is provided in the input unit of the power failure monitoring circuit 542. If the optical signal / electrical signal conversion unit 704 is provided in the connector 701, the connector 701 and the power outage are provided. This is because a hanging board can be connected to the monitoring circuit 542.

  As described above, the main control board 261 and the power supply board 313 are sealed by the main control board case 660, and the power supply board 313 (power failure monitoring circuit 542) and the open detection switch SW1 are connected by the optical fiber cable 703. Thus, fraud can be effectively prevented. This is because the hanging board cannot be electrically connected to the optical fiber cable 703. Further, by using the optical fiber cable 703, since the transmission signal is not affected by various noises generated in the gaming machine, an effect that the open detection signal can be accurately transmitted can be obtained.

  The optical signal / electrical signal conversion unit 704 is configured by, for example, a photodiode (PIN photodiode).

[Fourth form]
FIG. 28 is a perspective view of the vicinity of the open detection switch operation portion of the fourth embodiment.
On the upper surface of the inner frame 12, a thin plate-like closing member 620 is rotatably supported by a support shaft 621. When the front frame set 14 is closed, the closing member 620 is fixed by its own weight by the stopper 622 (see FIG. 28 (1)), and when the front frame set 14 is opened, the operation unit 600 protrudes. Thus, the closing member 620 is rotated while the operation unit 600 is pushed in, and is fixed by its own weight by the stopper 623 (see FIG. 28 (2)). Thereby, even when the front frame set 14 is in the open state, the operation unit 600 is pushed in, so the open detection switch SW1 does not output an open signal. As a result, the gaming state can be maintained while the front frame set 14 is opened. Therefore, when the store closing compensation is performed, even if the front frame set 14 is opened by operating the closing member 620, the gaming state does not stop. Therefore, a predetermined number of game balls are put into the big winning opening and paid out. It becomes possible.

  In addition, a closing switch is provided on the back side of the gaming machine, a discharge passage for guiding the stored ball to the tray and a sensor for detecting the number of payouts are provided, and the front frame set 14 is closed when performing the closing compensation.
