BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a gaming machine and a method of adjusting a volume thereof.
In a conventional gaming machine, when a player inserts a game medium such as coin or bill into an insertion slot of the gaming machine and presses a start button, symbols are variably displayed in a display mounted on a front of a cabinet and the symbols are then stopped automatically.
The gaming machine, as disclosed in U.S. Pat. No. 7,128,650, for example, comprises a sound circuit that outputs a sound signal, in which a variety of effect sounds such as background music, game effect sound and the like are overlapped, and a speaker that converts the sound signal into a sound wave and turns it up. Then, the machine carries out a game effect through the effect sound outputted from the speaker. When adjusting a volume of the effect sound, a volume adjustor is operated in the sound circuit, so that an output voltage of the sound signal is increased or decreased. As a result, the volumes of all the effect sounds such as background music or game effect sound included in the sound signal are adjusted into a same level by the volume adjustor.
The invention provides a gaming machine having an adjustment function of an effect sound, which is not provided to the conventional gaming machine, and a method of adjusting a volume thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiment

1

Hereinafter, it will be described a first embodiment of a gaming machine and a method of adjusting a volume thereof according to the invention. Meanwhile, in the following embodiment, a slot machine is described as an example of the gaming machine. However, it should be noted that the invention is not limited thereto.
(Volume Adjusting Method)
As shown in FIG. 1, a slot machine 10 executes a volume adjusting method comprising a first step of enabling a volume level of a sound signal, which becomes a background music (BGM) of a game, to be selected by an operation from an outside, a second step of changing a volume level of a sound signal that becomes a background music of a selected game into the selected volume level and a third step of converting a sound signal including at least a sound signal that becomes a background music of the game having the volume level changed and a sound signal that becomes a function music into a sound wave and turning it up. Herein, the function music is a voice sound representing an operating state of a game relating to an action of a player. For example, the function music includes a voice sound that is generated in inserting a coin, a voice sound that is generated in betting, a voice sound that is generated in paying out a coin and the like.
Thereby, it is possible to enable a player to hear the background music having a volume based on the selected volume level and the function music. Accordingly, when increasing the volume level of the background music, it is possible to enable the player to have a difficulty in hearing the function music. To the contrary, when decreasing the volume level of the background music, it is possible to enable the player to easily hear the function music. As a result, since it is possible to change the volume level of the function music in accordance with a provision environment of the gaming machine and the player's preference, the player can flexibly carry out an effect of the gaming machine by the voice sound including the background music and the function music.
For example, in FIG. 1, when a background music and a function music are outputted at the same time, it is possible to maintain a volume of a voice sound that is indicated as a speech bubble, even though an overall volume is decreased.
Furthermore, in the first step, a volume level of a sound signal that becomes a background music can be selectively inputted, based on a volume control signal received from an outside such as hall computer. Thereby, each slot machine 10 can collectively adjust the volumes, based on the volume control signal.
(Structure of the Volume Adjustment)
The volume adjusting method is carried out by the slot machine 10. The slot machine 10 comprises a game that is operated by a betting of a player, background music information of a sound signal that becomes a background music of the game, function music information of a sound signal that becomes a function music representing an operating state of the game relating to an action of the player, a volume level changer that can change a volume level of the sound signal that becomes a background music of the game, a selection switch that is adapted to be operated from an outside and selects a volume level of the sound signal that becomes a background music of the game, an adder that can add the sound signal that becomes a background music of the game having the volume level changed and a sound signal that becomes a function music, a speaker that converts the sound signal and turns it up and a game controller programmed to change, in the volume level changer, a volume level of the sound signal that becomes a background music of the game selected in the selection switch, to add, in the adder, at least the sound signal having the volume level changed and the sound signal that becomes a function music, and to turn up the added sound signal from the speaker.
In the embodiment, the slot machine 10 has a function of changing a sound signal that becomes a background music (hereinafter, referred to as background music signal) into a predetermined volume level so that it becomes a volume corresponding to an environment in a hall by an operation of a player or receptionist, thereby turning up the sound wave from the speaker together with at least the sound signal that becomes a function music (hereinafter, referred to as function music signal).
As shown in FIG. 2, the slot machine 10 has a main CPU 41, a sound signal output device 201, a volume level changer 211 and a voice sound output device 212. The sound signal output device 201 is connected to the main CPU 41 and outputs sound signals in parallel. The volume level changer 211 selectively changes a volume level of the sound signal that becomes a background music, among the sound signals outputted from the sound signal output device 201. The voice sound output device 212 overlaps the background music signal having the volume level changed, the function music signal in which the volume level is not changed and an effect sound signal and converts them into a sound wave. Herein, the effect sound signal indicates a sound signal that becomes an effect sound outputted from the speaker depending on the game states, rather than an action of the player.
The sound signal output device 201 has a main body PCB (Printed Circuit Board) 60 that outputs sound signals of a digital format in parallel and a D/A converter 210 that converts the sound signal outputted from the main body PCB 60 into an analog format. The D/A converter 210 has three output terminals 210 a, 210 b, 210 c. The output terminals 210 a, 210 b, 210 c output the sound signals, which are converted into the analog format in the D/A converter 210, in parallel. In the embodiment, each of the output terminals 210 a, 210 b, 210 c is adapted to output the background music signal, the function music signal and the effect sound signal, respectively.
The sound signal output device 201 is connected to the volume level changer 211 via first transmission lines 202 a, 202 b, 202 c so that it inputs the background music signal, the function music signal and the effect sound signal thereto. The volume level changer 211 has a signal switching unit 204, first to third attenuators 205 a, 205 b, 205 c, an adder 207, second transmission lines 208 a, 208 b, 208 c and an output bus 209.
The signal switching unit 204 has a single input terminal 213, three output terminals 214 a, 214 b, 214 c and a switch changeover terminal 219. The first attenuator 205 a has a single input terminal 215 a and a single output terminal 216 a. The second attenuator 205 b has a single input terminal 215 b and a single output terminal 216 b. The third attenuator 205 c has a single input terminal 215 c and a single output terminal 216 c. The adder 207 has three input terminals 217 a, 217 b, 217 c and a single output terminal 218.
The first transmission line 202, the second transmission line 208 and the output bus 209 are respectively formed by signal lines. The signal switching unit 204 is adapted to switch to which output terminals 214 a, 214 b, 214 c the sound signal inputted from the output terminal 213 is outputted. A switching signal is outputted in an operation timing of first to third selection buttons 70, 71, 72 and represents a connection state corresponding to the first to third selection switches 70S, 71S, 72S.
The first to third attenuators 205 a, 205 b, 205 c consist of fixed resistors decreasing an output of the sound signal. Meanwhile, the first to third attenuators 205 a, 205 b, 205 c are not limited to the resistors and may consist of an OP AMP, for example.
One ends of the first transmission lines 202 a˜202 c are respectively connected to the output terminals 210 a˜210 c of the D/A converter 210. The other end of the first transmission line 202 a is connected to the input terminal 213 of the signal switching unit 204. Thereby, the background music signal outputted from the D/A converter 210 is inputted to the signal switching unit 204 via the first transmission line 202 a.
The signal switching unit 204 switches to which output terminals 214 a, 214 b, 214 c the inputted background music signal is outputted, by a switching signal from the main body PCB 60. In the embodiment, when a first selection button 70 is pushed, the background music signal is outputted to the output terminal 214 a, when a second selection button 71 is pushed, the background music signal is outputted to the output terminal 214 b and when a third selection button 72 is pushed, the background music signal is outputted to the output terminal 214 c.
The one ends of the second transmission lines 208 a˜208 c are respectively connected to the output terminals 214 a˜214 c of the signal switching unit 204. The other ends of the second transmission lines 208 a, 208 b, 208 c are respectively connected to the input terminals 215 a, 215 b, 215 c of the first to third attenuators 205 a, 205 b, 205 c.
Thereby, when the background music signal is outputted to the output terminal 214 a from the signal switching unit 204, an output of the background music signal is decreased by the first attenuator 205 a and outputted to the output terminal 216 a. In the mean time, when the background music signal is outputted to the output terminal 214 b from the signal switching unit 204, an output of the background music signal is decreased by the second attenuator 205 b and outputted to the output terminal 216 b. In addition, when the background music signal is outputted to the output terminal 214 c from the signal switching unit 204, an output of the background music signal is decreased by the third attenuator 205 c and outputted to the output terminal 216 c.
Meanwhile, in the embodiment, the signal outputted from the signal switching unit 204 is adapted to pass to one of the first to third attenuators 205 a, 205 b, 205 c. However, the invention is not limited thereto. For example, by omitting the third attenuator 205 c from the volume level changer 211, an output level of the background music signal may not be changed when the background music signal is outputted from the output terminal 214 c. Thereby, it is possible to carry out an effect of the gaming machine by the voice sound including the background music and the function music, more flexibly.
The respective output terminals 216 a, 216 b, 216 c of the first to third attenuators 205 a, 205 b, 205 c are connected to the adder 207 through the signal line. The other ends of the first transmission lines 202 b, 202 c are connected to the adder 207.
Thereby, the background music signal in which the volume level thereof is changed by the first to third attenuators 205 a, 205 b, 205 c, the function music signal outputted from the output terminal 210 b of the D/A converter 210 and the effect sound signal outputted from the output terminal 210 c of the D/A converter 210 are inputted to the adder 207. Then, the adder 207 outputs a new sound signal from the output terminal, in which the background music signal having the volume level changed, the function music signal and the effect sound signal are added.
The volume level changer 211 structured as described above is connected to the sound voice output device 212. The sound voice output device 212 has a volume amplifier 206 and a speaker 29. The volume amplifier 206 is connected to an output terminal of the adder 207. The volume amplifier 206 amplifies the sound signal inputted from the adder 207 by a predetermined amplifying ratio. The volume amplifier 206 is connected to the speaker 29. The speaker 29 converts the sound signal into a sound wave and turns it up.
Meanwhile, in the embodiment, the volume adjustment is performed in the single slot machine 10 by forming a switching signal with the first to third selection switches 70S, 71S, 72S provided to the slot machine 10. However, the invention is not limited thereto. In other words, the volume adjusting method may be carried out in a system having several slot machines 10, a hall computer (not shown) and a communication network such as LAN or Internet that connects the slot machines 10 and the hall computer in a data communication manner. In this case, the hall computer can collectively change the volumes of the background music that are outputted from all the slot machines 10.
In addition, the slot machine 10 has sample music information of the sound signal that becomes a sample music including the background music having the volume level selectable by the selection buttons 70, 71, 72 and the function music. The slot machine may have a game controller programmed to use the sound signal of the sample music information when the first to third selection buttons 70, 71, 72 are operated, to change a volume level of the background music signal selected in the first to third selection buttons 70, 71, 72 and to output the background music signal from the speaker. In this case, since the sample music includes the background music and the function music, the player can easily change the volume level.
(Slot Machine 10)
In the followings, the slot machine 10 having the volume level changer 211 will be specifically described.
As shown in FIGS. 1 and 3, the slot machine 10 executes a playing method comprising steps of randomly selecting a scatter object symbol 181 from many symbols 180, rearranging the symbols 180 in a display, awarding a payout determined by a combination of the symbols 180 rearranged on a payline L, and when a predetermined number or more of the scatter object symbols 181 is rearranged, setting the scatter object symbol 181 as a scatter symbol 182, notifying a content of a payout determined on the basis of the scatter symbol 182 and awarding the payout.
In addition, the slot machine 10 executes a playing method comprising steps of providing a display area (scatter object symbol display unit 163) to a part different from an arrangement area (display windows 151˜155) for arranging the symbols 180 and displaying the scatter object symbol 181 in the display area, and when a predetermined number or more of the scatter object symbols 181 is rearranged, notifying that the scatter object symbol 181 is set as a scatter symbol 182.
Herein, the “arrangement” means a state in which the symbols 180 including the scatter symbol 182 are allowed to be visible with naked eyes of an exterior player. In other words, the symbols 180 are under state of being displayed in the display windows 151˜155. In the mean time, the “rearrangement” is meant by arranging the symbols 180 again after dismissing the arrangement of the symbols 180. In addition, the “payline” L is provided to determine a combination of the symbols 180. In other words, when the symbols 180 are rearranged on and out of the payline L, a combination is determined for only the symbols 180 rearranged on the pay line. As a result of the determination for a combination, when it is made a winning combination, it is carried out, for example, a process of paying out a coin in accordance with the winning combination.
In addition, the “scatter symbol” 182 is a symbol making it a condition that a winning is made through only the arrangement thereof, irrespective of the payline L. In other words, when the scatter symbol 182 is rearranged, a winning is made and it is carried out, for example, a process of paying out a coin on the basis of the number of all the scatter symbols 182 rearranged on and out of the payline L. The “scatter object symbol 181” is a symbol functioning as a scatter symbol on condition that a predetermined number or more of the symbols is rearranged. For example, in a case where a scatter object symbol is “BELL” and the number of rearrangement (set threshold) is set to be “3,” when three or more “BELLs” are rearranged, it functions as a scatter symbol and when two or less “BELLs” are rearranged, it functions as a typical symbol. In addition, the “symbol 180” means all symbols used in the slot machine 10 and includes the scatter symbol 182 and the scatter object symbol 181. The payline L, the symbol 180, the scatter symbol 182 and a winning combination will be more specifically described later.
(Display Unit 101)
As shown in FIG. 3, the slot machine 10 executing the above playing method is provided with a display unit 101 (display) and a game controller 100. The display unit 101 is structured to have the payline L and to arrange the symbols 180 including the scatter symbol 182. In addition, the display unit 101 is structured to provide the scatter object symbol display unit 163 (display area 101 b) to a part different from the display windows 151˜155 (arrangement area 101 a) for arranging the symbols 180.
The display unit 101 may be a mechanical structure with a reel device for arranging the symbols 180 by rotation of a reel or electrical structure with a video reel on which an image is displayed for arranging the symbols 180. Further, the display unit 101 may be a structure of combining a mechanical structure (reel) and an electrical structure (video reel). The electrical structure may include a liquid crystal device, a CRT (cathode-ray tube), a plasma display and the like. A detailed structure of the display unit 101 will be described later.
(Game Controller 100)
The game controller 100 is structured to execute a first process of randomly selecting a scatter object symbol 181 from many symbols 180, a second process of rearranging the symbols 180 in a display, a third process of awarding a payout determined by a combination of the symbols 180 rearranged on a payline L, and a fourth process of when a predetermined number or more of the scatter object symbols 181 is rearranged, setting the scatter object symbol 181 as a scatter symbol 182, notifying a content of a payout determined on the basis of the scatter symbol 182 and awarding the payout. In other words, the game controller 100 has a first processing unit, a second processing unit, a third process unit and a fourth processing unit.
In addition, the game controller 100 is structured to execute a fifth process of providing a display area 101 b (scatter object symbol display unit 163) to a part different from an arrangement area 101 a (display windows 151˜155) for arranging the symbols 180 and displaying the scatter object symbol 181 in the display area 101 b, and a sixth process of when a predetermined number or more of the scatter object symbols 181 is rearranged, notifying that the scatter object symbol 181 is set as a scatter symbol 182. In other words, the game controller 100 has a fifth processing unit and a sixth processing unit in addition to the first to fourth processing units.
The game controller 100 comprises a scatter object symbol memory 105 for storing the scatter object symbols 181, a scatter symbol memory 106 for storing a scatter symbol 182, a symbol memory 108 for storing all symbols including the scatter symbols 182 and a display symbol memory 107 for storing the symbols in the respective memories 105, 106, 108 as a display symbol. The display symbol memory 107 can be accessed by a display control unit 102. The display control unit 102 sets the arrangement area 101 a for arranging the symbols 180 and the display area 101 b for displaying the scatter object symbols 181 in the different parts of the display unit 101. In addition, the display control unit 102 reads out the symbols 180 in the display symbol memory 107 under control of a game executing unit 110 and displays the symbols 180 in the arrangements area 101 a and the scatter object symbols 181 in the display area 101 b. A detailed display state will be described later.
Further, the game controller 100 is connected to a game start unit 109. The game start unit 109 has a function of outputting a game start signal in accordance with control of the player. The game controller 100 comprises a game executing unit 110 for rearranging the symbols with an input of a game start signal, as trigger, from the game start unit 109, a combination payout determining unit 111 for determining a payout determined by a combination of the symbols rearranged on the payline in a unit game, a scatter symbol payout determining unit 112 for determining a payout determined on the basis of the scatter symbols rearranged on and out of the payline and a payout award unit 113 for awarding the respective payouts determined in the combination payout determining unit 111 and the scatter symbol payout determining unit 112.
In addition, the game controller 100 has a symbol determining unit 104 that is operated when a game start signal is inputted from the game start unit 109. The symbol determining unit 104 randomly selects the scatter object symbol 181 from the symbols 180. The symbol determining unit 104 outputs the scatter object symbol 181 to a rearrangement-number determining unit 114 and the scatter object symbol memory 105. The rearrangement-number determining unit 114 sets the scatter object symbol 181 as a scatter symbol 182 when a predetermined number of the scatter object symbols 181 is rearranged. In other words, the rearrangement-number determining unit 114 enables the scatter object symbol memory 105 to transmit the scatter object symbol 181 stored therein to the scatter symbol memory 106, thereby setting it as the scatter symbol 182.
Furthermore, the game controller 100 comprises an information output unit 116 and a game information memory 117 and a volume setting unit 230 connected to the information output unit 116. The game information memory 117 stores the background music data of a sound signal that becomes a background music of a game, the function music data of a sound signal that becomes a function music representing an operating state of a game relating to an action of a player and the sample music data of a sound signal that becomes a sample music having the background music and the function music. In addition, the game information memory 117 stores character data corresponding to the scatter symbol 182, payout-number data and description data and the like, in addition to the above information.
The volume setting unit 230 is adapted to be operated from an outside and to select a volume level of the sound signal. Specifically, it consists of the first to third selection switches 70S, 71S, 72S in FIG. 2 and the other switches. In the mean time, the volume setting unit 230 may be a touch panel provided to the display unit 101 of a liquid crystal display device. In addition, the volume setting unit 230 may be installed to an outside of the gaming machine and alternatively, may be installed in the gaming machine.
The information output unit 116 is adapted to read out the data stored in the game information memory 117 and to output it as a sound signal to the volume level changer 211. In addition, the information output unit 116 is adapted to output a switching signal of the volume setting unit 230 to the volume level changer 211. The volume level changer 211 is adapted to switch, by the switching signal, a volume level of the background signal that is to be changed. Thereby, the information output unit 116 reads out a variety of data from the game information memory 117 and outputs it to the volume level changer 211, thereby outputting a voice sound, in which the background music having the volume level selected on the basis of the switching signal and the function music are overlapped, through the volume amplifier 206 and the speaker 29.
In the mean time, each block of the game controller 100 may be structured with a hardware or software, as required.
(Operation of the Game Controller 100)
With the above structure, an operation of the game controller 100 will be described.
When a game start signal is outputted from the game start unit 109 through an operation of a player, the symbol determining unit 104 starts a process and the game executing unit 110 starts a unit game, so that the symbols 180 are rearranged (second process). The symbol determining unit 104 randomly selects a scatter object symbol 181 from the symbols 180 stored in the symbol memory 108 (first process). The determined scatter object symbol 181 is stored in the scatter object symbol memory 105 and is also used for a determination process in the rearrangement-number determining unit 114.
The scatter object symbol 181 stored in the scatter object symbol memory 105 is outputted to the display symbol memory 107 and then used for an image process in the display control unit 102, so that it is displayed in the display area 101 b of the display unit 101. In other words, the game controller 100 executes the fifth process of providing the display area 101 b to a part different from the arrangement area 101 a for arranging the symbols 180 and displaying the scatter object symbol 181 in the display area 101 b. Thereby, the player can easily recognize the scatter object symbol 181 since the scatter object symbol 181 is displayed in the display area 101 b separated from the arrangement area 101 a.
In addition, when the symbols 180 are rearranged as a unit game is executed, the rearrangement-number determining unit 114 specifies the scatter object symbol 181 among the rearranged symbols 180 and calculates a rearrangement-number of the scatter object symbol 181. Then, when the predetermined number or more of the scatter object symbols 181 is rearranged, it sets the scatter object symbol 181 as a scatter symbol 182. In other words, it transmits the scatter object symbol 181 stored in the scatter object symbol memory 105 to the scatter symbol memory 106. Thereby, the scatter object symbol 181 serves as a scatter symbol 182.
In addition, when the scatter symbol 182 is set, the information output unit 116 reads out the character data corresponding to the scatter symbol 182, the payout-number data and the description data from the game information memory 117 and outputs the data to the display control unit 102. Then, it is notified the contents of a payout determined on the basis of the scatter symbols 182 rearranged on and out of the payline L and the payout is awarded (fourth process). Further, the data is outputted to the volume level changer 211 and then outputted as voice sound from the speaker 29.
In addition, when the game is executed as described above, a function music representing a game start is outputted in starting a game and a function music representing a payout is outputted in awarding a payout. In addition to the function music, a background music is outputted. At this time, the background music has a volume level that is selected in the volume setting unit 230 by the volume level changer 211.
Thereby, since the player can select a background music that the player desires with respect to the function music, it is possible to decrease the displeasure of the player. In addition, when the volume setting unit 230 is operated, the sample music including the background music and the function music is outputted. Accordingly, it is possible to easily adjust the volume level.
(Display State)
It is specifically described an example of a display state of the display unit 101, with respect to the operation processes of the slot machine 10. In the mean time, as shown in FIG. 3, the display state is described with reference to a structure in which the display unit 101 arranges the symbols with a video reel manner.
The display unit 101 has display windows 151˜155 as the arrangement area for arranging the plural symbols. The display windows 151˜155 are arranged in a central part of the display unit 101. In the display windows 151˜155, symbol columns consisting of the plural symbols 180 are scroll-displayed. In addition, each of the display windows 151˜155 is divided into upper, center and lower stages 151 a, 151 b, 151 c. Each of the symbols 180 is stopped (arranged) in the respective stages 151 a, 151 b, 151 c. For example, in FIG. 3, “ORANGE” is stopped in the upper stage 151 a of the display window 151, “STRAWBERRY” is stopped in the center stage 151 b of the display window 151 and “BLUE 7” is stopped in the lower stage 151 c of the display window 151. As a result, the display windows 151˜155 display a symbol matrix consisting of 5 columns and 3 rows. In the mean time, the symbol matrix is not limited to 5 columns/3 rows.
In addition, the display unit 101 has the scatter object symbol display unit 163 as the display area for displaying the scatter object symbols 181. The scatter object symbol display unit 163 is arranged in a right-handed upper part of the display unit 101 so as not to overlap with the display windows 151˜155. In the mean time, the scatter object symbol display unit 163 may be provided in an arbitrary position on condition that it can avoid overlapping with the display windows 151˜155.
A selection object window 165 is provided below the scatter object symbol display unit 163. The selection object window 165 displays a symbol which will be a candidate for the scatter object symbol 181. Accordingly, the player can intuitively recognize that a scatter object symbol 181 is randomly selected among the candidate symbols displayed in the selection object window 165 and then displayed in the scatter object symbol display unit 163.
In addition, the display unit 101 has a scatter symbol display unit 171. The scatter symbol display unit 171 is basket-shaped, and displays the scatter symbol 182 as a received thing. The scatter symbol display unit 171 is provided to a left-handed upper corner part of the display unit 101. In the mean time, the scatter symbol display unit 171 may be provided to an arbitrary position on condition that it can avoid overlapping with the display windows 151˜155 and the scatter object symbol display unit 163.
A display state of FIG. 3 shows a state that the scatter symbol 182 has been set. Specifically, “ORNAGE” is displayed as a received thing in the scatter symbol display unit 171, through a series of operations that “ORANGE” displayed in the scatter object symbol display unit 163 is moved to the scatter symbol 182 and then received. As a result, the player can intuitively recognize that “ORANGE” has been set as the scatter symbol 182 by observing the displayed state of the scatter symbol 182 with naked eyes.
(Symbol, Combination, Etc.)
As shown in FIG. 5, the symbols 180 to be displayed in the display windows 151˜155 of the display unit 101 constitute columns of symbols by 22 symbols. The symbols constituting the respective columns of symbols are given with one code number of 0˜21. Each of the columns of symbols is constituted with a combination of symbols of “JACKPOT 7,” “BLUE 7,” “BELL,” “CHERRY,” “STRAWBERRY,” “PLUM,” “ORANGE” and “APPLE.”
The three successive symbols in the columns of symbols are displayed (arranged) in the upper, center and lower stages 151 a, 151 b, 151 c of the display windows 151˜155, respectively, so that they constitute a symbol matrix of 5 columns/3 rows. When a 1-BET button 26 or MAX-BET button 27 is pushed and then a spin button 23 is pushed, the symbols constituting the symbol matrix starts the scroll. When the scroll starts, the scrolls of the respective symbols are stopped (rearranged) after a predetermined time period has lapsed.
In addition, various winning combinations are predetermined with regard to the respective symbols. The winning combination is a combination that a combination of symbols stopped on the payline L becomes an advantageous state to the player. The advantageous state is a state in which a coin is paid out in accordance with the winning combination, the payout-number of coins is added to a credit, a bonus game is started, and the like.
Specifically, when a combination of “APPLE” symbol is stopped on the payline L, a bonus is triggered and a gaming state is shifted to a bonus game from a basic game. In addition, when a symbol of “CHERRY” is stopped on the payline L, 20 coins (game medium) are paid out per one bet. When a symbol of “PLUM” is stopped on the payline L, 5 coins are paid out per one bet.
In the mean time, a bonus game is a gaming state that is more advantageous than a basic game. In one embodiment, the bonus game is a free game. The free game is a gaming state allowing a player to play a game for a predetermined number of times, without betting a coin. The bonus game is not particularly limited as long as it is a gaming state advantageous to the player, i.e., it is more advantageous than the basic game. For example, the bonus game may include a state in which it is possible to obtain more game medium than the basic game, a state in which it is possible to obtain a game medium in a higher probability than in the basic game, a state in which a game medium is less consumed than in the basic game, and the like. Specifically, a free game, a second game and the like are examples of the bonus game.

The lamp 30 is turned on/off on the basis of the control signal outputted from the main CPU 41. The sub CPU controls the scroll of symbols of the display windows 151˜155 and is connected to a VDP (Video Display Processor). The VDP reads out image data of the symbol stored in an image data ROM, produces a scroll image to be displayed in the display windows 151˜155 and outputs the scroll image in the lower image display panel 16.
The hopper 66 is mounted in the cabinet 11 and pays out predetermined number of coins to the coin tray 18 from the coin payout slot 19, based on the control signal outputted from the main CPU 41. The coin sensor 67 is mounted in the coin payout slot 19 and outputs an input signal to the main CPU 41 when it detects that the predetermined number of coins are paid out from the coin payout slot 19.
The graphic board 68 controls an image display in the upper image display panel 33 and the lower image display panel 16, based on the control signal outputted from the main CPU 41. In addition, the graphic board 68 is provided with a VDP for producing image data on the basis of the control signal outputted from the main CPU 41, a video RAM for temporarily storing the image data produced by the VDP, and the like.
The bill validator 22 reads an image of the bill and accommodates the normal bill in the cabinet 11. In addition, in accommodating the normal bill, the bill validator 22 outputs an input signal to the main CPU 41, based on an amount of the bill. The main CPU 41 stores a credit-number, which corresponds to the amount of the bill transmitted by the input signal, in the RAM 43.
The ticket printer 35 prints a barcode having data encoded thereto, such as credit-number stored in the RAM 43, date and time, identification number of the slot machine 10 and the like, on a ticket, based on the control signal outputted from the main CPU 41, thereby outputting the ticket 39 having the barcode.
The card reader 36 reads the data from the smart card to transmit it to the main CPU 41, and writes the data into the smart card, based on the control signal outputted from the main CPU 41. The key switch 38S is mounted to the keypad 38, and outputs an input signal to the main CPU 41 when the player manipulates the keypad 38. The data displayer 37 displays the data which is read by the card reader 36 or the data which the player inputs through the keypad 38, based on the control signal outputted from the main CPU 41.
The door PCB 80 is connected with the control panel 20, a reverter 21S, a coin counter 21C and a cold cathode tube 81. The control panel 20 is provided with a spin switch 23S corresponding to the spin button 23, a change switch 24S corresponding to the change button 24, a cash out switch 25S corresponding to the cash out button 25, a 1-BET switch 26S corresponding to the 1-BET button 26 and a MAX-BET switch 27S corresponding to the MAX-BET button 27. Each of the switches 23S˜27S outputs an input signal to the main CPU 41 when each of the corresponding buttons 23˜27 is pushed by a player.
The coin counter 21C is mounted in the coin receiving slot 21 and validates whether a coin, which is inserted in the coin receiving slot 21 by the player, is normal or not. A coin except the normal coin is discharged from the coin payout slot 19. In addition, the coin counter 21C outputs an input signal to the main CPU 41 when it detects a normal coin.
The coin counter 21C is operated on the basis of the control signal outputted from the main CPU 41 and distributes a coin, which is recognized as a normal coin by the coin counter 21C, to a cash box (not shown) or hopper 66 mounted in the slot machine 10. In other words, when the hopper 66 is fully filled with the coins, the normal coin is distributed into the cash box by the reverter 21S. In the mean time, when the hopper 66 is not fully filled with the coins, the normal coin is distributed into the hopper 66. The cold cathode tube 81 functions as a backlight mounted to rear sides of the lower image display panel 16 and the upper image display panel 33 and is turned on, based on the control signal outputted from the main CPU 41.
(Volume Adjustment)
Hereinafter, it is described a volume adjustment that is performed in the slot machine 10. As the main CPU 41 executes a volume adjustment processing routine of FIG. 8, it is determined whether one of the first to third selection buttons 70, 71, 72 is operated by the player (S101). When the first to third selection buttons 70, 71, 72 are not operated (S101, NO), this routine is ended and a standby state is made until the operation is carried out.
When the first to third selection buttons 70, 71, 72 are operated (S101, YES), a switching signal corresponding to the first to third selection buttons 70, 71, 72 is outputted to the volume level changer 211 (S102). Then, the sample music data is outputted to the volume level changer 211 (S103). After a predetermined time period of standby elapses (S104), this routine is ended.
Thereby, as shown in FIG. 2, the sample music data is outputted to the D/A converter 210 via the main body PCB 60 and then is converted into an analog signal format. A background music signal is outputted from the first output terminal 210 a of the D/A converter 210 and a function music signal is outputted from the second output terminal 210 b. The background music signal passes to a connection passage corresponding to the switching signal of the signal switching unit 204 and is then outputted to the first to third attenuators 205 a, 205 b, 205 c specified by the switching signal.
After the volume level of the background music signal is decreased in the first to third attenuators 205 a, 205 b, 205 c, the background music signal is overlapped with the function music signal in the adder 207, which is then outputted to the volume amplifier 206. Then, the sample music in which the volume of the background music is decreased is outputted from the speaker 29, so that the player having operated the first to third selection buttons 70, 71, 72 hears the sound. The player determines whether the sample music is proper or not. When the player is dissatisfied with the volume of the background music with respect to the function music, the player may tentatively hear a next sample music by operating the first to third selection buttons 70, 71, 72, and adjust the volume so that it becomes a desired volume.
(Processing Operation)
In the followings, it will be described a process which is carried out in the slot machine 10 wherein the volume is adjusted as described above. When the main CPU 41 reads out and executes the game program, a game is started. As shown in FIG. 7, in the game executing process, it is determined whether a coin is bet (S10). In this process, it is determined whether it is received an input signal from the 1-BET switch 26S as the 1-BET button 26 is pushed and whether it is received an input signal from the MAX-BET switch 27S as the MAX-BET button 27 is pushed. When the coin is not bet (S10, NO), the step of S10 is re-executed and it is under standby state until a coin is bet.
In the mean time, when the coin is bet (S10, YES), the credit-number stored in the RAM 43 is subtracted, correspondingly to the number of coins bet (S11). Meanwhile, if the number of coins bet is larger than the credit-number stored in the RAM 43, it is not carried out the process of subtracting the credit-number and the step of S11 is re-executed. In addition, if the number of coins bet is above the upper limit (50 pieces in this embodiment) which can be bet per one game, it is not carried out the process of subtracting the credit-number and a step of S12 is carried out.
Next, it is determined whether the spin button 23 is ON or not (S12). When the spin button 23 is not ON (S12, NO), the procedure is returned to the step of S10. Meanwhile, when the spin button 23 has not been ON (for example, the spin button 23 is not ON and an instruction to end the game is inputted), it is canceled the subtraction result in the step of S11.
In the mean time, when the spin button 23 is ON (S12, YES), a symbol determining process is executed (S13). In other words, a stop symbol determining program stored in the RAM 43 is executed, so that it is determined the symbols 180 which will be stopped in the fifteen respective stages of the display windows 151˜155. Thereby, it is determined a combination of symbols to be stopped on the payline L.
Then, the symbols 180 of the display windows 151˜155 are scroll-displayed (S14). In the mean time, the scroll process is such that the symbols 180 are scrolled in an arrow direction and then the symbols 180 determined in the step of S13 are stopped (rearranged) in the display windows 151˜155.
After that, a scatter object symbol determining process is executed (S15). In other words, a scatter object symbol 181 is randomly determined from the symbols 180 of “BELL,” “CHERRY,” “STRAWBERRY,” “PLUM,” “ORANGE” and “APPLE.” Then, the determined scatter object symbol 181 is displayed in the scatter object symbol display unit 163.
When the scroll of the symbols 180 is stopped, it is acquired a rearrangement-number of the scatter object symbol 181 (S16). Then, it is determined whether the rearrangement-number is a set threshold or more (S17). When it is a set threshold or more (S17, YES), the scatter object symbol 181 is set as a scatter symbol 182. Specifically, the scatter object symbol 181 is displayed as a received thing in the scatter symbol display unit 171, through a series of operations that the scatter object symbol 181 is moved from the scatter object symbol display unit 163 to the scatter symbol display unit 171 and then received in the scatter symbol display unit 171 (S18).
After that, a character 251 is displayed between the scatter symbol display unit 171 and the scatter object symbol display unit 163 and a speech bubble representing a speech content of the character 251 is displayed. In addition, the speech content of the character 251 is outputted with a voice sound. Specifically, an original description image 252 of “ORANGE has become a scatter symbol” is displayed in the speech bubble and is voice-outputted (S19).
After that, a payout process is carried out. In other words, it is summed a payout-number of coins based on a winning combination and a payout-number of coins based on the display number of the scatter symbols 182. Then, when the coins to be paid out are stored, a predetermined number of credits is added to a credit-number that is stored in the RAM 43. In the mean time, when paying out the coins, a control signal is transmitted to the hopper 66, so that a predetermined number of coins is paid out (S20).
In the mean time, when the rearrangement number is not a set threshold or more (S17, NO), it is determined whether a combination of the symbols 180 stopped on the payline L is a winning combination (S23). When it is not a winning combination (S23, NO), the combination is neither the scatter symbol 182 nor a winning combination. This means a blank, so that this routine is ended.
In the mean time, when the combination is a winning combination (S23, YES), the step of S20 is executed. After that, it is determined whether a bonus trigger is made as the winning combination. In other words, it is determined whether a combination of “APPLE” is arranged on the payline L (S21). When it is determined that a bonus trigger is made (S21, YES), a bonus game process is executed (S22). Meanwhile, when a bonus trigger is not made (S21, NO), this means a blank, so that this routine is ended.

Embodiment 2

In the followings, a second embodiment of the gaming machine and the volume adjusting method thereof according to the invention will be described. In the mean time, the same member as the first embodiment is provided with a same reference numeral and the description thereof is omitted. In addition, the descriptions of the structure and operation same as the first embodiment is omitted.
(Volume Adjusting Method)
A slot machine 10 according to this embodiment comprises a gaming machine cabinet, a game that is operated by a betting of a player, background music information of a sound signal that becomes a background music of the game, function music information of a sound signal that becomes a function music representing an operating state of the game relating to an action of the player, a volume level changer capable of changing a volume level of the sound signal that becomes a background music of the game, a selection switch that can be operated from an outside and selects a volume level of the sound signal that becomes a background music of the game, an adjustment switch that is provided in the gaming machine cabinet and can adjust a volume level of the sound signal that becomes a background music of the game selected by the selection switch, and an adder that adds a sound signal that becomes a background music of the game having the volume level changed and a sound signal that becomes a function music, a speaker that converts the sound signal into a sound wave and turns it up, and a game controller programmed to change, in the volume level changer, a volume level of the sound signal that becomes a background music of a game selected in the selection switch, to add, in the adder, at least the sound signal having the volume level changed and the sound signal that becomes a function music and to turn up the added sound signal from the speaker.
According to the above structure, it is possible to select a volume level of the sound signal that becomes a background music of a game. Furthermore, after the sound signal that becomes a background music of the game is changed into the selected volume level, the sound signal having added the sound signal that becomes a background music and the sound signal that becomes a function music is converted into a sound wave and then is turned up.
As a result, it is possible to enable a player to hear the background music having a volume based on the selected volume level and the function music. Accordingly, when increasing the volume level of the background music, it is possible to enable the player to have a difficulty in hearing the function music. To the contrary, when decreasing the volume level of the background music, it is possible to enable the player to easily hear the function music. Thereby, since it is possible to change the volume level of the function music in accordance with a provision environment of the gaming machine and the player's preference, the player can flexibly carry out an effect of the gaming machine by the voice sound including the background music and the function music. In addition, since the adder adds the background music signal and the function music signal, it is possible to handle the background music and the function music as a same signal.
Furthermore, the adjustment switch capable of setting a volume level, which can be selected by a player using the selection switch, is provided in a gaming machine cabinet. Thereby, a manager of the gaming machine can enable a player to select a volume level of the background music, from a volume level that a manager such as receptionist desires.
Specifically, as shown in FIG. 9, the slot machine 10 is different from the first embodiment 1 in that it has first to third adjustment switches 73S, 74S, 75S. In addition, it is different from the first embodiment in that it is connected to the main body PCB 60 and the first to third attenuators 205 a, 205 b, 205 c through the signal lines. Furthermore, as compared to the first embodiment, the first to third attenuators 205 a, 205 b, 205 c consist of variable resistors that decrease an output of a sound signal.
In this embodiment, the first to third adjustment switches 73S, 74S, 75S are electrically connected to the main CPU 41. In addition, the first to third adjustment switches 73S, 74S, 75S are provided in the cabinet 11. Accordingly, the player cannot adjust the first to third adjustment switches 73S, 74S, 75S. At a timing at which a manager such as receptionist operates any of the first to third adjustment switches 73S, 74S, 75S in the cabinet 11, an adjustment signal is transmitted from the main body PCB 60 to the first to third attenuators 205 a, 205 b, 205 c corresponding to the first to third adjustment switches 73S, 74S, 75S.
The adjustment signal includes the information about the resistance magnitudes of the first to third attenuators 205 a, 205 b, 205 c, which are determined in accordance with the operation amount of the first to third adjustment switches 73S, 74S, 75S. Based on the information about the resistance magnitudes, any resistance magnitude of the first to third attenuators 205 a, 205 b, 205 c corresponding to the first to third adjustment switches 73S, 74S, 75S operated is adjusted in accordance with the operation amount. The other structures are same as the first embodiment.
