The embodiment of the present invention will be specifically described with reference to the following examples.
(Example)
This example is an example related to a pachinko gaming machine 1 having a function of displaying symbols in a variable manner. This will be described with reference to FIGS.

  A pachinko gaming machine 1 illustrated in FIG. 1 is a gaming machine that is played using a pachinko ball as a game medium. This pachinko gaming machine 1 is a so-called seven machine that executes a jackpot lottery in accordance with a winning at the special drawing start winning opening 12 and executes symbol variation representing a lottery result. In the pachinko gaming machine 1, as a gaming state other than the big hit state, in addition to a normal state where the player's advantage degree is low, a probability variation state where the winning probability of the big hit lottery is increased is set. As the jackpot, in addition to a normal jackpot, a probability variation jackpot with a probability variation state in which the winning probability of the jackpot lottery is increased is set.

  The pachinko gaming machine 1 has an open / close door 13 attached to a frame (not shown), and a substantially circular gaming area 130 is formed on the inside gaming board surface. A speaker 131 is disposed at the lower left of the game area 130, and a ball supply dish 135 and a lower dish 137 are provided in two upper and lower stages below the game area 130. On the lower right side of the ball supply tray 135, an operation handle 15 is further erected for firing the balls of the ball supply tray 135 toward the game area 130.

  The open / close door 13 is fixed to the frame so as to be rotatable through a hinge 133 located on the left side facing the pachinko gaming machine 1. The open / close door 13 is provided with a substantially circular transparent window 139 corresponding to the game area 130, and decorative lamp portions 132 arranged on both sides of the upper portion of the transparent window 139.

The ball supply tray 135 is a tray for receiving a prize ball paid out in accordance with a winning prize, a ball rental, or the like. The balls of the ball supply tray 135 are supplied to a launching device 341 (see FIG. 2) via a supply passage (not shown).
The lower plate 137 is a plate that receives balls or the like exceeding the storage limit of the ball supply plate 135.

  The game area 130 is an area where pachinko balls, which are game media, flow down. In the game area 130, a special figure start winning opening 12, a passing gate 14, a big winning device 16, and the like are arranged around the effect display unit 5 that variably displays symbols. At the bottom of the game area 130, an out hole 138 is opened for collecting balls that have flowed down without winning. On the left side edge of the game area 130, a special figure display unit 182 and a general figure display unit 183 having seven segments are arranged.

The passing gate 14 is a gate that detects a passing ball. The payout of the winning ball is not set to the passing gate 14 that only allows the ball to pass. The passing gate 14 is a winning opening that is a trigger for the usual drawing. When a ball wins the passing gate 14, a random number for lottery for normal symbol determination (hereinafter referred to as common symbol determination) is extracted, and the normal symbol lottery is executed. The winning probability of the normal drawing lottery is 1/30 in the normal state, and 1/1 in the probability variation state and the short time state.
The universal map display unit 183 is a display unit for displaying whether or not the universal map lottery is successful.

  The special figure display unit 182 is a display unit that displays a symbol indicating the result of the jackpot lottery. However, the symbol displayed by the special symbol display unit 182 is a symbolic symbol representing control information inside the gaming machine, and it is difficult for a general player to grasp the result of the big hit lottery. The notification of the result of the jackpot lottery for the player is performed by a design for production by the production display unit 5.

  The special figure start winning opening 12 is a winning opening (three payout balls) that triggers a big hit lottery. When a ball wins the special drawing start winning opening 12, a lottery random number for the jackpot lottery is extracted and the jackpot lottery is executed. The special drawing start winning opening 12 is constituted by an electric chew (electric tulip) in which a pair of movable blades 121 are provided in the opening 120.

  The pair of movable blades 121 in a normal state is in a state of standing so as to face each other with a gap (a state indicated by a dotted line in FIG. 1). In this state, the ball may win only through a gap corresponding to one ball that opens upward. On the other hand, the pair of movable blades 121 (states shown by solid lines in the figure) rotated so as to be separated from each other act like a tray that guides the inflow of balls into the opening 120. In such an open state, winning to the special drawing start winning opening 12 easily occurs. The opening time of the special figure start winning opening 12 is 0.2 seconds in the normal state and 1.5 seconds × 3 times in the probability variation state.

  The grand prize winning device 16 is a variable prize winning device called a so-called attacker that opens the grand prize winning opening 160. The attacker 16 is disposed below the special drawing start winning opening 12. The attacker 16 has a large winning opening 160 having a horizontally long rectangular shape and a lid member 161 that seals the large winning opening 160.

  The normal-time attacker 16 has the lid member 161 positioned so as to be substantially flush with the board surface forming the game area 130, and the special winning opening 160 is closed. When the lid member 161 is rotated to the near side, the big prize opening 160 is opened, and the lid member 161 functions as a tray for guiding the ball to the big prize opening 160. It should be noted that the payout at the time of winning the grand prize opening 160 is 15 balls.

  The effect display unit 5 is a display unit constituting symbol display means for displaying a predetermined symbol in accordance with the result of the big hit lottery. The effect display unit 5 informs the general player of the result of the lottery lottery by an effect design. The effect display unit 5 can display an 8-digit numeric symbol as an effect symbol. There are eleven types of numbers in each digit, with “.” (Decimal point) added to each symbol of “0-9”.

  In particular, the effect display unit 5 of this example is a model of a Nixie tube, which is a kind of cold cathode discharge tube that is often used as a display in the 1960s to 70s, for example. A Nixie tube is a specific number or letter generated by glow discharge that emits red-orange light over a cathode by selectively applying a voltage to one of a plurality of types of cathodes in the form of numbers or letters. It is a display that displays characters. The Nixie tube has declined due to the widespread use of 7-segment displays since the 1970s, and in the 1990s, all major manufacturers ended production. According to the production display unit 5 simulating a Nixie tube, it is possible to produce a similar retro effect without using a Nixie tube that is difficult to obtain at present. The specific configuration and operation of the effect display unit 5 will be described in detail later.

  The pachinko gaming machine 1 stops and displays a predetermined jackpot symbol (for example, an 8-digit number) for a production when the jackpot win is generated, and notifies the winning display by displaying the winning display on the production display unit 5. Is generated. Note that the probability variation ratio in which the probability variation state in which the jackpot winning probability increases after the jackpot state ends is set to 50% when the jackpot state occurs. When the probable jackpot status is won, the jackpot symbol for the probable jackpot (for example, an odd number of 8 digits) is stopped, and when the normal jackpot status that is not followed by the probable status is won, the normal jackpot symbol ( For example, an even number of 8 digits) is stopped and displayed.

  Next, the electrical configuration of the pachinko gaming machine 1 will be described with reference to FIG. The pachinko gaming machine 1 is configured around a main control unit 20 in which a main control circuit is formed. For the main control unit 20, a payout control unit 33 that controls the payout of balls, a firing control unit 34 that controls the driving of balls, an effect control unit 35 that controls game effects, and an effect display unit 5 are controlled. Display control unit 36, winning ball or passing ball detection sensors 312 to 314, an electric chew solenoid 322 that opens the special drawing start winning port (electric chew) 12, a large winning port solenoid 324 that opens the attacker 16, and an electric power supply A power supply circuit portion 328 and the like are electrically connected.

  As a detection sensor for a winning ball or a passing ball, a special drawing starting sensor 313 for detecting a winning ball to the special drawing starting winning port 12, a general drawing starting sensor 312 for detecting a passing ball of the passing gate 14, and an attacker 16 There is a large winning sensor 314 for detecting a winning ball.

In addition to the amplifier 133, the speaker 131, and the decorative lamp unit 132 being electrically connected to the effect control unit 35, the display control unit 36 is communicably connected. The display control unit 36 constitutes symbol display means for displaying a predetermined symbol according to the result of the big hit lottery.
When a winning occurs, the payout control unit 33 receives an instruction signal from the main control unit 20 and controls the payout mechanism unit 331 so that a predetermined number of balls are paid out.
The firing control unit 34 controls the launching device 341 in accordance with the operation angle of the operation handle 15 to control the ball launch strength.

  As shown in FIG. 2, the main control unit 20 includes a CPU (Central Processing Unit) 28, a ROM (Read Only Memory) 29 / RAM (Random Access Memory) 24, which is a storage element, and a random number generator that generates a predetermined range of random numbers. 27, a random number extraction unit 26 for extracting a lottery random number, an I / O (Input / Output) 25 serving as an input / output interface, and the like.

  As shown in FIG. 2, the RAM 24 is a readable / writable storage element used for the work area of the CPU 28 or temporary writing. The storage area of the RAM 24 is provided with a holding area for storing lottery random numbers for jackpot lottery as holding random numbers.

The ROM 29 stores various processing programs to be executed by the CPU 28, and stores a lottery table for big hit lottery (not shown) and a lottery table for normal determination.
In the lottery table for jackpot lottery, a jackpot winning random number is defined for each of the normal state and the probability variation state. In each lottery table of this example, winning random numbers are defined such that the jackpot winning probability in the normal state is 1/300 and the jackpot winning probability in the probability variation state is 1/30.

As shown in FIG. 2, the main control unit 20 causes the CPU 28 to execute a program read from the ROM 29, thereby realizing the following functions as each means.
(1) Lottery means: means for performing a big hit lottery when a predetermined lottery condition is satisfied. As a lottery condition, the winning of a ball to the special drawing start winning opening 12 is set, and the lottery means performs a lottery process by acquiring a random number for lottery extracted by the random number extraction unit 26 according to the establishment of the lottery condition. Run.
(2) Storage means: means for storing a lottery random number for jackpot lottery as special figure hold. The storage means stores special figure hold with a limit of 4 as an example of a predetermined upper limit hold number.
(3) Reading means: means for reading the special figure hold one by one in order from the oldest stored time according to the end of the symbol variation.
(4) Win / fail judgment means: means for judging whether or not the special figure hold read by the reading means (whether or not the jackpot is won).
(5) Jackpot generating means: means for generating a jackpot state that is advantageous to the player when the jackpot symbol is stopped and displayed on the effect display unit 5 constituting the symbol display means.

  An outline of the basic operation of the pachinko gaming machine 1 of the present example configured as described above will be described. When the operation handle 15 is operated in the clockwise direction, the pachinko gaming machine 1 launches a ball with an intensity corresponding to the operation angle. The fired ball flows down through the game area 130 in which the passing gate 14 and the like are arranged. The balls that have not won are collected from the out holes 138 provided at the lowermost part of the game area 130.

  When the main control unit 20 detects a ball passing through the passing gate 14, the main control unit 20 executes a lottery process for extracting a random number for lottery for normal determination from random numbers generated by the random number generation unit 27, so Once the symbol is determined, the usual symbol change starts. The usual fluctuation time is 30 seconds in the normal state and 5 seconds in the probable state. When the normal symbol variation stops and matches the preset winning symbol, the special symbol start winning opening (electric chew) 12 is opened. The opening time of the special figure start winning opening 12 is 0.3 seconds in the normal state and 3 seconds in the probability variation state.

  When the main control unit 20 detects a winning ball in the special drawing start winning opening 12, the main control unit 20 executes a lottery process for extracting a random number for lottery in the big hit lottery. If the design display unit 5 is not changing the symbol, the main control unit 20 immediately matches the lottery random number for the big win lottery with the winning random number in the lottery table for the big hit lottery to determine whether or not the big hit lottery is successful. On the other hand, if the symbol is changing, the lottery random number for the big hit lottery is temporarily stored as a special figure hold, and the reserved number is temporarily stored in the special figure hold area with an upper limit of four. Since the upper limit number of special figure hold is four, the maximum number of random numbers for lottery lottery stored by the main control unit 20 is one in the design variation, four stored as the reserved random number, The total is 5. In addition, when the number of holds in the special figure reservation area is the upper limit number of four, when a ball wins the special figure start winning opening 12, the lottery process is not executed and the random numbers for lottery are not extracted. ing.

  In other gaming states in which the big hit state is not occurring, the main control unit 20 reads one by one in order from the oldest stored timing of the special figure hold in the special figure hold area when the variable display of symbols stops Then, after changing the fluctuation time of the special figure, the fluctuation of the symbol is started. With respect to the read lottery random numbers with special figure hold, whether or not to win the big hit lottery is determined.

  The main control unit 20 generates a jackpot state when the symbol variation of the special symbol by the special symbol display unit 182 stops and coincides with a preset jackpot symbol (not shown). At this time, in synchronization with the stoppage of the special figure on the special figure display unit 182, a predetermined jackpot symbol is stopped and displayed on the presentation display unit 5 for variably displaying the symbol for presentation, thereby notifying the winner of the big prize. Is called. Note that during the occurrence of the big hit state, even if there is a pending random number, reading is not performed and the special figure change by the special figure display unit 182 is not executed.

  As described above, as the jackpot, in addition to a normal jackpot, a probability variation jackpot is set in which a probability variation state occurs after the end of the jackpot state. The normal jackpot and the probabilistic jackpot are each assigned with a probability of 1/2. When the jackpot state triggered by the probability change jackpot ends, the state shifts to a probability change state (probability variation state), and the winning probability of the jackpot becomes 10 times that of the normal state. This probabilistic state continues until the big hit lottery is won. If the winning jackpot is won, the probabilistic state will occur again after the jackpot state ends, and then the probable state will end in accordance with the normal jackpot winning.

Next, the configuration and operation of the effect display unit 5 which are characteristic in the pachinko gaming machine 1 of this example will be described with reference to FIGS.
As described above, the production display unit 5 is a display unit that produces a retro feeling by imitating a Nixie tube. The effect display unit 5 is a display device in which a plurality of light guide plates 51 (11 in this example) on which a predetermined design (effect design) is printed by an inkjet method are stacked in the depth direction.

  The effect display unit 5 includes a housing 50 that houses a light guide plate 51 that overlaps in the depth direction. The front side of the housing 50, that is, the front side of the effect display unit 5 is formed of a transparent member so that the player can expect. In particular, the effect display unit 5 of the present example is similar to eight Nixie tubes arranged in parallel in the horizontal direction, and the vertical display-like transparent resin cover 59 is provided on the front of the effect display unit 5. Are arranged in parallel in the horizontal direction.

  As shown in FIG. 4, eight light guide plates 51 are arranged in the horizontal direction in a state of being connected to each other via a connecting portion 518, thereby forming a horizontally elongated light guide panel 51 </ b> P as a whole. Inside the casing 50 of the effect display unit 5, eleven light guide panels 51P are stacked in the depth direction, whereby eight sets of eleven light guide plates 51 in the depth direction are arranged in parallel in the horizontal direction. Yes. In the effect display unit 5, each set in which a plurality of light guide plates 51 (11 in this example) are stacked in the depth direction constitutes one display unit corresponding to one Nixie tube. A plurality of units (eight in this example) are arranged in the horizontal direction.

  The eleven light guide panels 51P have the same shape specification, but have different printed designs. In the light guide panel 51P, a slit 519 is provided in the gap between the adjacent light guide plates 51, and the adjacent light guide plates 51 are connected via two connecting portions 518 located near both ends in the longitudinal direction of the strip-shaped light guide plate 51. It is connected. One of the two connecting portions 518 is formed so as to be flush with the side surface of the end portion in the longitudinal direction of the light guide plate 51, and the other connecting portion 518 is formed from the end portion in the longitudinal direction of the light guide plate 51. Is also slightly recessed. The end portion of the light guide plate 51 on the other connecting portion 518 side individually protrudes in a peninsular shape to form a light guide end portion 511 suitable for taking light into each light guide plate 51.

  In each light guide plate 51 of each light guide panel 51P, in addition to “0” to “9”, among the 11 types of numerical symbols such as “.” (Decimal point), the same type of symbols is printed. For example, a numerical symbol “1” is printed on each light guide plate 51 of a certain light guide panel 51P, and a numerical symbol “2” is printed on each light guide plate 51 of another light guide panel 51P. .

  In the 11 light guide panels 51P, the five light guide panels 51P with the light guide end portions 511 positioned on the upper side and the six light guide panels 51P with the light guide end portions 511 positioned on the lower side are staggered. (See FIGS. 4 and 5). Of the 11 light guide panels 51P, the light guide panel 51P closest to the player side has the light guide end 511 positioned on the lower side. The six light guide panels 51P with the light guide end portions 511 positioned on the lower side (left column in FIG. 4) are “1”, “2”, “3” in order from the player closest to the player side. , “4”, “5”, “.” (Decimal point) symbols are printed. In the five light guide panels 51P with the light guide end portions 511 located on the upper side (the right column in FIG. 4), “0”, “9”, “8”, The symbols “7” and “6” are printed.

  As shown in FIGS. 5 and 6, the light shielding member 53 and the electrical decoration board 55 are arranged on the upper and lower sides corresponding to both sides in the vertical direction of the 11 light guide panels 51 </ b> P overlapping in the depth direction with the electrical decoration board 55 facing outside. ing. The light shielding member 53 is a member in which a plurality of bar-shaped light shielding spacers 530 having a rectangular cross section are arranged in parallel at predetermined intervals. A gap of a predetermined interval formed between adjacent light shielding spacers 530 or a gap of a predetermined interval formed between the light shielding spacer 530 and a member on the housing 50 side is a groove-like shape that accommodates the light guide end portion 511 of the light guide panel 51P. A support groove 539 is formed.

  Since there are six light guide panels 51P with the light guide end portions 511 positioned on the lower side (left column in FIG. 4), the lower light shielding members 53 form six rows of support grooves 539. In addition, since there are five light guide panels 51P on which the light guide end portions 511 are positioned on the upper side (the right column in FIG. 4), the upper light shielding member 53 forms five support grooves 539. Of the side surfaces of the light shielding spacer 530, the side surface opposite to the electrical decoration substrate 55 is configured to support the flush side surface of the light guide panel 51 </ b> P opposite to the light guide end 511. The light shielding spacer 530 of the lower light shielding member 53 supports the same side surface of the light guide panel 51P where the light guide end portion 511 is positioned on the upper side, and the light shielding spacer 530 of the upper light shielding member 53 is the light guide end portion. 511 supports the flush side surface of the light guide panel 51P located on the lower side.

  5 and 6 is a substrate on which LEDs 551 as light emitting elements are arranged in a matrix. The LEDs 551 are arranged in a matrix of 8 rows and 5 columns on the illumination board 55 adjacent to the upper light shielding member 53, and the matrix of 8 rows and 6 columns is arranged on the illumination board 55 adjacent to the lower light shielding member 53. LEDs 551 are arranged in a shape. Each LED 551 of the electric decoration board 55 is arranged along the support groove 539 of the light shielding member 53 and individually faces each light guide end portion 511 of the light guide panel 51P.

  Each of the LEDs 551 in the 8 rows and 5 columns of the upper illumination board 55 and each of the LEDs 551 in the 8 rows and 6 columns of the lower illumination board 55 correspond to one of the light guide plates 51 individually. When any one of the LEDs 551 is turned on, the lighting light is guided to the light guide plate 51 corresponding to the LED 551, and the symbol printed on the light guide plate 51 emits light.

  The display control unit 36 that constitutes the symbol display means together with the effect display unit 5 is a control unit that switches and displays symbols by turning on / off each of the light guide plates 51. The display control unit 36 controls lighting / extinguishing of the LEDs 551 on the upper and lower lighting boards 55 of the effect display unit 5 to turn on one of the light guide plates 51 in each digit, thereby generating a desired number string. Display. In addition, the display control unit 36 can be incorporated into the casing 50 of the effect display unit 5 and integrally formed.

  As described above, in the effect display unit 5 that is the symbol display means of the pachinko gaming machine 1 of the present example, a plurality of light guide plates 51 on which a predetermined symbol is printed by the ink jet method are provided in an overlapping manner. The symbol can be switched and displayed by turning on / off. According to the gaming machine provided with the display unit 5 for production, it is possible to execute a display with high taste and full of retro feeling reminiscent of a conventional Nixie tube. In addition, if the light guide plate 51 on which a predetermined pattern is printed by the ink jet method is used, the effect display unit can be configured at a considerably lower cost than the Nixie tube.

  In the effect display unit 5, eleven light guide plates 51 are provided in the depth direction, and eight display units simulating one Nixie tube are arranged side by side in the horizontal direction. According to the effect display unit 5, it is possible to display a maximum of eight-digit numeric symbols, and various effects can be achieved.

  In the production display unit 5 of this example, by using the ink-jet type light guide plate 51, it is possible to share processing parts for printing a design. The initial cost can be suppressed when a plurality of light guide plates 51 having the same shape are used or when the display contents are changed.

  For example, in the case of an electroformed mold, it is necessary to change a stamper as a mold in order to change display contents, and there is a circumstance that only a fixed one can be made. On the other hand, the ink jet type light guide plate 51 is very advantageous in that the design and characters of the light guide plate 51 can be arbitrarily changed by ink jet type printing, and the display contents can be changed relatively easily. For this reason, the structure of the effect display unit 5 using the light guide plate 51 printed by the inkjet method is very effective as a display lamp for displaying not only numbers but also about several types of fixed symbols and characters. Note that printing by laser processing may be employed instead of printing by the ink jet method.

  In the presentation display unit 5 of this example, the electrical decoration boards 55 are arranged on both the upper and lower sides, and light shielding between the light guide plates 51 is performed by the light shielding members 53 arranged along the surface of the electrical decoration board 55. It is compatible with both support. Compared with the case where the light shielding member 53 and the electric decoration board 55 are configured on one side, the device size in the depth direction is suppressed, and a compact housing 50 that can be easily incorporated into a gaming machine is realized.

  Incidentally, in the application of light guide plates to gaming machines, at present, use of effects and effects is common. In production / effect applications, it is very effective to produce an image that appears as if a design or the like has been lifted up by light guiding where it is normally transparent and invisible. In manufacturing the light guide plate, it is necessary to perform high-precision optical design and high-precision molding using an electroforming mold so that the light guide plate is normally transparent and visible only when light enters from the end face. For this reason, there is a problem that the usage cost is limited because the initial cost is high and the product is uniform.

  On the other hand, in the case of the production display unit 5 of this example simulating a Nixie tube that can be seen even when the cathode shaped like a number or a character is turned off, the transparency of the light guide plate 51 when turned off may be a problem. However, the lower the number is, the more transparent the numbers are, the better the purpose of producing a retro feeling of the Nixie tube.

Instead of or in addition to the configuration of this example, the following configuration may be employed. Further, the following configurations may be combined as appropriate.
In this example, 11 light guide plates 51 are stacked in one display unit corresponding to each digit of the effect display unit 5 capable of displaying 8-digit symbols. However, the number of light guide plates 51 is two or more. Any number is acceptable.
Although the configuration in which eight display units with light guide plates are arranged in the horizontal direction is illustrated, the number of the display units arranged in the horizontal direction is not limited and may be one.

Although a number is illustrated as a symbol of the light guide plate 51, any symbol may be used. Two or more symbols may be printed on one light guide plate.
In addition, the display unit corresponding to each digit of the effect display unit 5 has the same number of light guide plates 51 and combinations of symbols stacked in the depth direction, but the number of light guide plates and the combinations of symbols are different for each display unit. May be different.

  Although a pachinko gaming machine has been exemplified as a gaming machine, a slot machine may be used. As a pachinko machine, it may be a type that pays out balls according to winnings, or it is a so-called enclosed pachinko machine that uses points to fire balls and is awarded points according to winnings. Also good. The slot machine may be of a type that is played using medals, coins, etc. as a game medium (game value), but using medals or other points as a game value (betting) It may be a so-called complete credit type slot machine that can be played and points are awarded when winning. In the case of a slot machine, the symbol display means displays a predetermined symbol according to the lottery result of a bonus combination (such as a big bonus or a regular bonus), thereby informing the player that the bonus combination is won internally. To do.
