Description

[0001]
[Industrial application fields]
The present invention relates to a reel for a gaming machine in which a plurality of symbols are arranged on a belt-like portion on the outer periphery, and a symbol variable display game comprising a symbol display unit by a symbol variable display simulating this kind of reel or reel. Related to the machine.
[0002]
[Prior art]
In a conventional typical slot machine, three symbol display windows are formed side by side on the front panel on the front side, and three reels are arranged inside the fuselage corresponding to the position where each symbol display window is formed. Has been. Each reel is generally formed by adhering a belt-like sheet on which a plurality of symbols such as numerals and symbols are drawn on the outer periphery of the reel frame, and after starting to rotate all at once according to the player's starting operation, Each is stopped sequentially by an individual stop operation. On the front panel symbol display window, there are 5 winning lines, upper, middle, lower, right-up, and right-down. By stopping each reel, three winning lines are displayed on each winning line. The symbols are displayed in an aligned state.
[0003]
In addition, in the conventional slot machine, whether or not to win a prize is determined by internal lottery and the reel stop operation is controlled, and when winning or `` reach '' is established, or when the lottery is won, In order to effectively notify the player, various configurations are added.
[0004]
As this type of notification means, the most typical one is a lamp provided at an appropriate position on the front surface of the aircraft. In addition to this, when a symbol on the winning line is identified and displayed, a light source such as a bean lamp is placed inside the reel corresponding to the stop display position of each symbol, and a specific symbol stops on the winning line. In addition, there is a model in which back lighting is applied to the symbol. Furthermore, in recent years, it has also been proposed that a specific symbol is formed transparent or semi-transparent, and the specific symbol is emitted with a predetermined color light by applying back lighting to the symbol (Japanese Patent Laid-Open No. 10-290856). Issue gazette).
[0005]
In place of the printed winning line, line indicators such as LEDs and optical fibers are provided, and when a predetermined condition is satisfied during the game, the line indicator is turned on to identify the predetermined winning line. A model for display is also proposed (Japanese Utility Model Laid-Open No. 62-84484, Japanese Patent Laid-Open No. 6-23092).
[0006]
[Problems to be solved by the invention]
Each symbol in a conventional reel is generally drawn by silk screen printing on an outer belt-like sheet, and the color scheme of each symbol is fixed. Therefore, even if the back lighting is applied to the symbol, the color of the symbol does not change, and it is impossible to set different prizes for the same symbol or to make various notifications by diversifying the symbol display. is there.
[0007]
Further, when the winning line is displayed by light emission by the line indicator, the winning line becomes unclear when the indicator is not lit. In order to solve this problem, if the emission color is switched between the normal time and the notification time, it is necessary to provide a switch mechanism or the like, resulting in a problem that the configuration becomes complicated and the cost is increased.
In addition, there is a problem that notifications that only turn on the lamps on the front panel or output sound are not interesting and cannot sufficiently raise the player's expectation.
[0008]
In addition, in recent slot machines, a plurality of types of game modes are set for “special prizes” that guarantee a large amount of medal payout, and for each mode, for example, “7” in red and “7” in green As described above, there is a symbol in which “7” symbols having different display colors are set. However, when a plurality of types of winning symbols are provided in this way, the setting of the symbol arrangement and the reel stop control become complicated, and there is a problem that a great deal of time is required for development.
[0009]
  The present invention has been made by paying attention to the above-mentioned problems.For a particular symbolBy changing the color of the print pattern, an object is to increase the notification effect when notifying various information, and to enhance the effect of performing the game and to prevent the game from becoming monotonous.
[0011]
[Means for Solving the Problems]
  According to this inventionIn the variable symbol display game machine, a plurality of reels each having a plurality of symbols drawn on a translucent belt-like sheet on the outer periphery are arranged behind the symbol display window. When each reel is stopped, a symbol display window is provided for each reel. The symbols for a predetermined number of frames are stopped and displayed in the inside of each reel.Deployed for each symbol stop display position,Light is emitted toward the symbol display window.pluralA light source;eachTurn on and off the light sourceIndividualAnd a control circuit for controlling. Belt strip sheet of the reelOn the back side, a light-shielding layer is provided over the entire portion that corresponds to the background of the symbol, and at the position where the specific symbol isA multilayer printing pattern in which two types of translucent printing layers are superimposed in the thickness direction of the belt-like sheetBy said specificSymbolThe symbol is formed by a print pattern of a single print layer at a symbol formation position other than the specific symbol.ing. In the multilayer printed pattern, the first printed layer is located on the outer side and the second printed layer is located on the inner side. When the light source is turned on, light emitted from the second printed layer is emitted by light traveling from the inner side to the outer side of the reel. When the color is transmitted to the outside of the reel through the first print layer and the light source is turned off, the first print layer prevents the second print layer from being visible from the outside of the reel. The first printed layer isDark pigmentIt is formed by mixing particles and clear material particles having high light transmittance, and the second printed layer includes pigment particles having a hue different from that of the first printed layer and having high brightness. It is formed in a semi-transparent layer.
[0012]
  Further, according to the present invention, when the specific symbol is stopped and displayed in the symbol display window, the control circuit switches the light source on / off state corresponding to the stop display position, and stops the stop at the specific symbol. When the light source corresponding to the display position is turned off, a dark color corresponding to the dark pigment particles is displayed, and when the light source corresponding to the stop display position is turned on, the clear material particles are passed through. The light emitted from the second print layer is transmitted and displayed by the transmitted light.
[0020]
[Action]
  When a specific symbol is stopped and displayed in the symbol display window, if the light source corresponding to the stop display position is turned off, the specific symbol isDark by the first printed layerIn colorexpressed. HoweverThe light source is onWhen illumination is performed from the inside of the reel, the emission color in the second printed layer is transmitted to the outside of the reel through the first printed layer.It is transparent and the display color of a specific symbol changes to a bright and vivid color.
[0027]
【Example】
FIG. 1 shows an appearance of a slot machine according to an embodiment of the present invention, and FIG. 2 shows an internal structure of the machine body.
The slot machine 1 in the illustrated example is configured by assembling a door portion 3 in an opening portion of a body body portion 2 having a front opening. A control board 5 on which a reel block 4 and a control circuit are mounted is provided at an upper position in the machine body, and a medal dispenser 6 having a hopper 6a is incorporated at a lower position.
[0028]
The reel block 4 is formed by assembling three reels 8a, 8b, and 8c to a metal frame 7. As shown in FIG. 3, each reel 8 a, 8 b, 8 c is formed by sticking a belt-like sheet 30 on which a plurality of types of symbols S are drawn on the outer peripheral surface of the reel frame 29. A symbol for establishing a prize is formed.
These reels 8a, 8b, and 8c are assembled together with stepping motors 9a, 9b, and 9c, which serve as their drive sources, on support plates 10a, 10b, and 10c arranged at one side positions, respectively.
[0029]
The door 3 is formed by assembling panels 11, 12, and 13 on the upper, middle and lower parts of a metal frame, respectively. The front panel 11 is mainly for displaying the symbols of the reels 8a, 8b, and 8c, and transparent tempered glass or an acrylic synthetic resin plate is used. Each of the upper and lower panels 12 and 13 is made of a transparent synthetic resin plate such as acrylic, and a pattern such as a character or character representing a model name or game information is drawn. Each of the panels 11, 12, and 13 is subjected to silk screen printing on the surface, thereby drawing characters and designs and coloring the background portion.
[0030]
In addition to the medal slot 16, the frame portion between the front panel 11 and the lower panel 13 has three stop button switches 15a, 15b, 15c, and three stop button switches for each of the start lever 14, reels 8a, 8b, and 8c. Bet button switches 17, 18, 19, a settlement switch 22, a changeover switch 23 and the like are provided. The upper panel 12 is provided with a hit display lamp 27 for informing “big hit”, and a medal payout outlet 25 and a medal tray 26 are provided below the lower panel 13, respectively.
[0031]
The slot machine 1 is a credit-type machine that stores a large number of medals in an electronic data format in a control circuit and executes a game while consuming the stored medals. The bet button switch 17 provided on the overhanging surface is for playing a game by consuming three stored medals. In addition, the bet button switches 18 and 19 provided on the lower vertical surface are for consuming two and one stored medal, respectively. Further, the settlement switch 22 is used to settle the stored medals so that a considerable number of medals are paid out from the medal payout opening 25 to the medal tray 26, and the changeover switch 23 is used in the credit game mode or the medal insertion slot. This is for selecting one of the game modes in which medals are directly inserted from 16.
In the following description, the terms “medal insertion” indicate the concepts of both direct medal insertion from the medal insertion slot 16 and medal consumption from the stored medal.
[0032]
In the central front panel 11, rectangular symbol display windows 20a, 20b, and 20c that are not colored are formed corresponding to the arrangement positions of the reels of the reel block 4, respectively.
As shown in FIG. 4, the symbol display windows 20a, 20b, and 20c are each formed in a vertically long shape having a size corresponding to the reel width in the horizontal direction and the display range for three symbols S in the length direction. Has been. Further, on the surface of the front panel 11, five winning lines along each of the upper, middle, and lower horizontal directions, and the right-down and right-up diagonal directions so as to cross the symbol display windows 20 a, 20 b, and 20 c. L1 to L5 are drawn, and when the reels 8a, 8b and 8c are stopped, the three symbols S are aligned and stopped for each of the pay lines L1 to L5.
[0033]
The winning lines L1 to L5 are activated according to the number of medals inserted, and the center horizontal line L1 is increased by inserting one medal and the upper, middle, and lower three lines are inserted. Horizontal lines L1, L2, and L3 are activated. When three medals are inserted, all winning lines L1 to L5 are activated.
[0034]
Furthermore, in the slot machine 1 of this embodiment, a light source 28 for illuminating the symbols is arranged on the back side of each reel 8a, 8b, 8c in correspondence with the stop position of each symbol.
As shown in FIG. 5, each light source 28 is a surface light emitter formed by mounting a number of LED chips 32 on a substrate 31 and molding a resin 33 containing a diffusing material thereon, and each reel 8a, Three light sources 28 for each of 8b and 8c are connected and fixedly arranged inside each reel 8a, 8b and 8c as a light source unit 28A.
[0035]
FIG. 6 shows an example of attachment of the light source unit 28A.
A semicircular mounting plate 35 is attached to the front edge of each of the support plates 10a, 10b, 10c for each reel 8a, 8b, 8c along the annular portion of the reel. The light source unit 28A for each reel 8a, 8b, 8c is supported by screws 36, 36 inside the mounting plate 35 with each light source 28 positioned behind the respective symbol stop position.
The light source 28 does not necessarily need to use a surface light emitter as described above. For example, a light source having a structure in which a bean lamp is accommodated in the case body may be used.
[0036]
Further, in the slot machine 1 of this embodiment, among the symbols S arranged on the reels 8a, 8b, 8c, a specific symbol such as the numeral “7” is printed using a printing pattern according to the method shown in FIG. Thus, the symbol display color under back illumination by the light source 28 is changed to a color different from the normal time.
[0037]
This print pattern is formed by two types of print layers 37 and 38 superimposed on the back surface of the belt-like sheet 30 along the thickness direction of the sheet.
Of the printing layers 37 and 38, the first printing layer 37 in contact with the back surface of the belt-like sheet 30 is a low-lightness pigment having a hue such as black, silver, pearl, or dark green (hereinafter referred to as “dark pigment”). And a clear material particle 40 having a high light transmittance are mixed at a predetermined ratio. On the other hand, the second print layer 38 is a translucent layer that includes pigment particles 41 having a hue different from that of the first print layer and having high brightness. In addition, it is not necessary for any of the print layers 37 and 38 to include only a single pigment particle, and the outline portion of the symbol and the inside of the outline are represented by different colors using a plurality of color pigments. You may draw a fine pattern.
[0038]
The symbols other than the specific symbols are formed by forming a pattern with a single printed layer on the back surface of the belt-like sheet 30 as in the conventional case. On the back surface of the belt-like sheet 30, a light shielding layer 42 made of a dark color pigment is formed on the entire background portion excluding the formation positions of the symbols.
[0039]
When the symbols having the two-layer printing pattern as described above are arranged on the reels 8a, 8b, and 8c, the light from the light source 28 is emitted from the second printing layer 38 and the light under the back illumination by the light source 28. After passing through the clear material particles 40 of the first printing layer 37, the surface of the belt-like sheet 30 is reached, so that the light emission pattern in the second printing layer 38 from the outer position of the reel through the first printing layer 37. Can be visually recognized. Further, since the second printed layer 38 is illuminated brightly by receiving the back illumination, the color of the symbol is vividly expressed.
[0040]
On the other hand, when the light source 28 is turned off, the second print layer 38 does not emit light and there is no light transmitted through the clear material particles 40. Therefore, the dark pigment of the first print layer 37 is eliminated. The low-lightness color due to the color becomes dominant, and the second printed layer 38 is not visually recognized from the outside of the reel.
[0041]
As described above, in order to switch between the state in which the second print layer 38 can be visually recognized and the state in which the second print layer 38 cannot be visually recognized by back lighting, each particle 39 of the dark color pigment and the clear material in the first print layer is substantially used. , 40 particle size, and the mixing ratio of both. For example, when black pigment particles having a diameter of 20 microns and clear material particles having a diameter of 40 microns are used, they may be mixed at a ratio of about 1: 1.
[0042]
For example, when the number “7” symbol is formed by the two-layer printing pattern, the first printing layer 37 includes a black pigment, and the second printing layer 38 uses a pigment such as red or yellow. Once formed, the symbol is represented in black as shown in FIG. 8 (1) under the condition that no back lighting is applied. However, when this symbol is back illuminated, the emission color of the second print layer 38 is transmitted through the first print layer 37 and the belt-like sheet 30 according to the principle described above. As shown in (), the color changes from black to bright colors such as red and yellow. Further, the symbol is displayed brighter by the back lighting, and the color emitted by the second printed layer 38 becomes brighter.
In the example of FIG. 8, the outline portion of the symbol “7” is formed using a pigment having a color different from the inside of the symbol, and the color of the outline portion is also changed depending on the presence or absence of back lighting. .
[0043]
  Furthermore, in the said Example, each printing layer 37 and 38 is made into strip | belt shape.SheetIt is formed by overlapping on the back surface of, but not limited to this,SheetThe second printed layer 38 may be formed on the surface 30 and the first printed layer 37 may be further formed thereon. Also stripSheetThe first printed layer 37 is formed on the front surface 30 and the second printed layer 38 is formed on the back surface, and the light emission pattern in the second printed layer is formed in a strip shape.SheetFurther, the light may be transmitted through the first print layer.
[0044]
In this embodiment, the entire symbol is formed by a two-layer printing pattern. However, the present invention is not limited to this, and the outline portion of the symbol is formed in a single layer structure with a dark pigment so that the outline is emphasized, or only a part of the symbol is formed. A layer printing pattern may be used. The symbol may be formed by a normal printing pattern, and the surrounding background portion may be formed by a two-layer printing pattern. Further, each of the reels 8a, 8b, and 8c is not limited to the configuration shown in FIG. 3, and may be configured to have a cylindrical shape whose peripheral surface is transparent or translucent, for example.
[0045]
Further, the first printing layer 37 is not limited to the configuration shown in FIG. 7, and printing with high transparency is achieved by multicolor printing of four types of pigments of cyan (C), yellow (Y), magenta (M), and black (K). A layer may be formed.
Further, if a fluorescent pigment is included in the second printed layer 38 and an ultraviolet lamp is provided as the light source 28, the symbol display under the back illumination can be further emphasized.
[0046]
FIG. 9 shows an electrical configuration of the slot machine 1.
In the figure, reference numeral 43 denotes a control unit comprising a microcomputer, a CPU 44 which is the main body of control and calculation, a ROM 45 storing a program and a table for lottery, a RAM 46 used for reading and writing data, and a random number generator 47.
[0047]
Various input / output units are connected to the CPU 44 via a bus 51. The CPU 44 recognizes various input signals based on a program in the ROM 45, and gives a drive signal to the output unit to provide a series of games. Execute the process. As an input unit, in addition to the start lever 14, the stop button switches 15a, 15b, 15c, the bet button switches 17, 18, 19, the settlement switch 22, the changeover switch 23, a medal inserted from the medal slot 16 is detected. For this, a medal detection sensor 48 or the like is connected. The output unit includes a medal dispenser 6, a reel drive unit 49 that drives the stepping motors 9a, 9b, and 9c, a hit notification lamp 27, and an audio circuit 50 that outputs sound effects and the like for the above-described back lighting. The light source 28 is connected.
[0048]
FIG. 10 shows a series of game control procedures in the slot machine 1.
The CPU 44 validates a predetermined number of pay lines in response to input signals from the bed button switches 17, 18, 19 or the medal detection sensor 48 (ST1, 2). Next, when the operation signal of the start lever 14 is received, ST3 becomes “YES” and it is checked whether or not a winning flag is set (ST4).
[0049]
Here, the winning flag is a flag for storing and holding that the lottery has become a “hit”, and if the lottery result of “hit” has been carried over from the previous game, the determination of ST4 Becomes “YES”, and the process proceeds to the reel start process of ST8.
[0050]
If the winning flag is not set, the process proceeds to ST5, where the random number output from the random number generator 47 is taken in and a lottery is executed. Further, if this lottery becomes a “hit”, the CPU 44 sets a winning flag in the next ST7 and then proceeds to ST8 to start the reels 8a, 8b and 8c all at once.
[0051]
Thereafter, each time the stop button switches 15a, 15b, 15c are operated, the CPU 44 slides the corresponding reels 8a, 8b, 8c to a maximum of 4 frames to stop the lottery result on the effective winning line. The symbols corresponding to are stopped as much as possible (ST9, 10). When all the reels 8a, 8b, 8c are stopped and the same symbols are aligned on an effective winning line, a winning is achieved and a predetermined number of medals are paid out (ST11 to 13).
[0052]
Further, when the winning is based on a special symbol combination such as “7”, ST14 is “YES”. In response to this, the CPU 44 resets the winning flag in ST15 and then turns on the light source 28 behind the stop position of the symbol “7” to change the display color of the symbol “7” in ST16. The symbol display with the different display colors is continued for a predetermined time, after which the CPU 44 turns off the light source 28 and executes a special game having a high winning probability a predetermined number of times (ST17, 18).
[0053]
On the other hand, despite the fact that the lottery is a “hit”, there is a case where “7” symbols are not drawn on the target winning line in any of the reels and become “out of place”. In such a case, the CPU 44 proceeds to ST20 via ST14 and 19, and corresponds to the symbol “7” that has been successfully pulled in and the symbol “7” that has stopped from the target pull-in position. The identification is displayed by blinking the light source. When the predetermined time has elapsed, the CPU 44 cancels the blinking display (ST21), and waits for the start of the next game with the winning flag carried over.
[0054]
In this way, by changing the display color of the symbol using the two-layer printing pattern and back lighting, the player can understand that the production at the time of the special prize is raised or that the internal lottery has become a `` big hit '' It is possible to increase the interest in the game by easily informing.
[0055]
In addition, the symbols based on the two-layer printing pattern can be used not only for notification but also for setting a plurality of winnings having different control modes.
For example, when two types of winnings, “Big Bonus” and “Regular Bonus” are set as special winnings, the “Regular Bonus” is made to correspond to a combination of symbols of “7” in dark colors without back lighting. The “Big Bonus” is associated with a combination of “7” symbols in bright colors by back lighting.
[0056]
In addition, as the “big bonus”, two types of modes with different conditions for the special game executed after winning a prize may be set, and “7” symbols of different colors may be assigned to each mode. With this method, it is not necessary to assign two types of “7” symbols to each of the reels 8a, 8b, and 8c, so that symbol arrangement setting and reel stop control can be simplified.
[0057]
Furthermore, the two-layer printing pattern can be introduced not only to the reel but also to a printing pattern drawn on a winning line of a symbol display window or a panel surface.
FIG. 11 shows an example in which the central winning line L1 is formed by a two-layer printing pattern among the five winning lines L1 to L5. In this printing pattern, the same two kinds of printing layers 37 and 38 as those described above are superimposed on the front surface or the back surface of the front panel 11, or the first and second printing layers are respectively formed on the front and back surfaces of the panel 11. 37 and 38 are formed.
[0058]
The first printing layer 37 of the winning line L1 is formed by mixing a dark pigment such as black or gold and a clear material, and the other four winning lines L2 to L5 are simply made of pigments of the same color as the winning line L1. It is formed by one printing layer. Further, the second printed layer 38 of the winning line L1 is formed as a translucent layer containing a pigment having high brightness such as red.
Further, on the back side of the front panel 11, light sources 52 by LEDs are arranged at both side positions of the respective symbol display windows 20a, 20b, 20c, corresponding to the position and direction of the winning line L1.
[0059]
Therefore, when the light source 52 is not turned on, the winning lines L1 to L5 are displayed in the same color. However, when the light source 52 is turned on, the emission color of the second print layer 38 is emitted from the central winning line L1. Appears and the display color and brightness change.
[0060]
Such a color change display of the winning line is effective when used for notification when the above-described internal lottery becomes a “hit”. Unlike the symbols, the winning line has a fixed display position, and is always placed in a position that will be visible to the player during the game, so the time between when the winning flag is set and when the special winning is established The notification effect is enhanced by maintaining the changed display color.
If the other winning lines L2 to L5 are also formed by the two-layer printing pattern, the activated winning line can be identified and displayed, or used for the purpose of informing the winning line.
[0061]
FIG. 12 shows an example in which the lower panel 13 shows the character information 53 by the two-layer printing pattern. The printing pattern in this case is also such that two types of printing layers 37 and 38 similar to the above are superimposed on the front or back surface of the lower panel 13, or the first and second printing layers on the front and back surfaces of the panel, respectively. 37 and 38 are formed. The print pattern 53 may be a symbol representing a character of a gaming machine or the like in addition to the characters shown in the illustrated example. The character and design portions may be formed by a normal printing pattern, and the background portion may be formed by a two-layer printing pattern.
[0062]
A light source (not shown) such as a bean lamp is provided on the back side of the lower panel 13 so as to correspond to the arrangement position of the character information 53. By turning on this light source at a predetermined timing, as shown in FIGS. 12 (1) and 12 (2), the color of the print pattern is changed, and a vivid color display is realized under back illumination by the light source.
[0063]
This type of printing pattern can be formed on portions other than the symbol display windows 20a, 20b, and 20c of the upper panel 12 and the front panel 11, and can greatly enhance effects such as when winning a prize. .
In addition, although the embodiment in which the two-layer printing pattern is formed at a predetermined position of the slot machine has been described here, it is also introduced to other symbol variable display game machines having a plurality of symbol rows that can be variably displayed, such as a pachinko game machine. Needless to say, you can.
