DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a block diagram showing a configuration formed of slot machines 13 according to the present invention, and instruments connected to the slot machines 13. In FIG. 1, a cellular phone 300, a points management server 400, and a conversion rate management server 500 are connected to the slot machines 13 through a network 600. Moreover, cellular phones 300 of players are connectable to the slot machines 13 through wireless transmitting/receiving parts 171 (refer to FIG. 2). A connection method for the cellular phones 300 of the players will be described later.
Each of the cellular phones 300 of the players transmits, to the slot machine 13, points data for adding credits of a game executed in the slot machine 13. On the cellular phone 300 of the player, an IC chip (not shown) is mounted for storing the points data and making wireless communication with the slot machine 13.
The points management server 400 stores a plurality of game programs to be downloaded, which are to be executed by the cellular phones 300 of the players.
A description will be given of an example of a method by which a player's cellular phone 300 acquires points. The cellular phone 300 of the player downloads a program executable by the cellular phone from the points management server 400 through the network 600. A payment of cash necessary to download the program includes payment by electronic money and by credit. Types of currencies, such as “Dollar”, “Yen”, and “Euro”, are selectable by operating the cellular phone 300. When the cellular phone 300 downloads the game program, a cellular phone ID for identifying the cellular phone 300 and an initial points are given to the cellular phone 300 by the points management server 400. The value of the points data changes by executing the game thus downloaded. An ending condition of the game is that the value of the points data becomes zero, or that the player performs an operation for ending the game, and points data at the time of ending the game is stored in a storage part of the cellular phone 300. The data stored in the storage part of the cellular phone 300 at this time of ending the tame corresponds to a part of contents shown in a first authentication table (refer to FIG. 10), which are the cellular phone ID, an address of the points management server 400, and the currency type of the cash paid out when the game program is downloaded.
The points management server 400 stores a second authentication table (refer to FIG. 11). Here, under a condition that the game is ended, the cellular phone 300 transmits total points of the first authentication table to the points management server 400 together with the cellular phone ID. The points management server 400 stores the received total points and cellular phone ID in the second authentication table. In this way, the total points acquired by the cellular phone 300 can be managed by the points management server, and under a condition that the total points stored by the cellular phone 300 and the total points stored by the points management server always match, it can be authenticated that the total points stored by the cellular phone 300 has a correct value.
When the player resumes the game, the cellular phone 300 transmits the total points stored thereby to the points management server 400 together with the cellular phone ID. In this process, when the total points stored by the points management server 400 and the cellular phone 300 are different from each other, rewriting processing for replacing the total points stored by the cellular phone 300 by the total points stored by the points management server 400 takes place. In this processing, the points management server 400 transmits an error message to the cellular phone 300 together with the total points, and rewrites the total points stored by the cellular phone 300 after the cellular phone 300 displays the error message and displays the fact that the total points will be rewritten.
The conversion rate management server 500 stores a conversion rate table (refer to FIG. 13) for use in converting the points data into the credits in the slot machine 13.
Each slot machine 13 is a slot machine which allows the player to play a basic game. Moreover, the slot machine 13 converts the points data into the credits by receiving the points data from the cellular phone 300 of the player. In order to perform such conversion, the slot machine 13 receives data of a conversion rate from the conversion rate management server 500. A method of the conversion will be described later.
As described above, the player transmits the points data stored in the cellular phone 300 to the slot machine 13, thus making it possible to convert the points data into the credits and to play the basic game. Accordingly, the player can purchase the credits easily. Therefore, enjoyment of the game is enhanced.

Thus, the liquid crystal display 30 is composed of a front panel 31 including the touch panel 32 and a display plate 33, the transparent liquid crystal panel 34, a light guide plate 35, a reflection film 36, fluorescent lamps 37 a, 37 b, 38 a and 38 b as so-called white light sources, lamp holders 39 a, 39 b, 39 c, 39 d, 39 e, 39 f, 39 g and 39 h, and a table carrier package (TCP) on which an IC for driving the transparent liquid crystal panel is mounted. Note that, though the TCP is not specifically shown in FIG. 5 and FIG. 6, the TCP is composed of a flexible board (not shown) connected to a terminal part of the transparent liquid crystal panel 34, and the like.
The liquid crystal display 30 is provided on a front side of the display areas of the mechanical reels 3A to 3E (on a front side of the display surface 31 a) so as to straddle the mechanical reels 3A to 3E. The mechanical reels 3A to 3E and the liquid crystal display 30 are provided so as to be spaced from each other at a predetermined interval. Note that, in the case of the video reels, the image reels are displayed on the liquid crystal display 30 in place of the mechanical reels 3A to 3E.
The touch panel 32 is composed of a transparent member. The display plate 33 is composed of a transparent member. On the display plate 33, the picture pattern and the like are formed at a position corresponding to an area between the display plate 33 and the above-described variety of display parts 48 to 50, and the like. Specifically, the area of the display plate 33, where the picture pattern and the like are formed, is the picture pattern-formed area 31 b on the front panel 31, and on the other hand, an area of the display plate 33, where the picture pattern and the like are not formed, is the display surface 31 a on the front panel 31 (refer to FIG. 3). Alternatively, the entire surface of the front panel 31 may be made as the display surface 31 a without forming the picture pattern-formed area 31 b on the front panel 31. In this case, the picture pattern just needs not to be formed on the display plate 33, or the display plate 33 just needs to be omitted.
In FIG. 5 and FIG. 6, an electric circuit and the like for operating the variety of display parts 48 to 50 arranged on a back surface side of the display plate 33 is not shown.
The transparent liquid crystal panel 34 is formed by sealing liquid crystal into a gap between a transparent substrate such as a glass plate on which a thin-film transistor layer is formed and a transparent substrate opposite thereto. A display mode of the transparent liquid crystal panel 34 is set to be normally white. The normally white display mode indicates that the display turns white in a state where the liquid crystal is not activated (light transmitting to a display surface side is visually recognizable from the outside). As described above, the transparent liquid crystal panel 34 set to be normally white is employed, and thus variation display and still display of the respective symbols of the mechanical reels 3A to 3E can be visually recognized even if a situation where the liquid crystal cannot be activated occurs. Accordingly, the player can continue the game. Specifically, even if such a situation as described above occurs, the game in which the rearrangement of the symbols of the respective mechanical reels 3A to 3E is mainly necessary can be played.
The light guide plate 35 is for guiding the light from the florescent lamps 37 a and 37 b to the transparent liquid crystal panel 34 (in other words, for illuminating the transparent liquid crystal panel 34), and is composed of a transparent member (having a light guide function) of acrylic resin or the like, which is provided on a back side of the transparent liquid crystal panel 34 and has a thickness of, for example, approximately 2 cm.
For the reflection film 36, for example, a white polyester film or an aluminum thin film is used, on which a silver-deposited film is formed. The reflection film 36 reflects the light guided into the light guide plate 35 toward a front surface side of the light guide plate 35. The reflection film 36 is composed of a reflection area 36A and a non-reflection area (transmission area) 36B. The non-reflection area 36B is formed of a transparent material, and provided on an area including a part of the front panel 31, which covers fronts of the mechanical reels 3A to 3E.
The fluorescent lamps 37 a and 37 b are arranged along an upper end part and lower end part of the light guide plate 35, and both ends thereof are supported by the lamp holders 39 a, 39 b, 39 g and 39 h. Light irradiated from the fluorescent lamps 37 a and 37 b is reflected on the reflection area 36A of the reflection film 36, and illuminates the transparent liquid crystal panel 34. On the other hand, the fluorescent lamps 38 a and 38 b are arranged toward the mechanical reels 3A to 3E at an upper position and a lower position on a back side of the reflection film 36, and both ends thereof are supported by the lamp holders 39 c, 39 d, 30 e and 39 f. Light emitted from the fluorescent lamps 38 a and 38 b, reflected on the surfaces of the mechanical reels 3A to 3E, and made incident onto the non-reflection area 36B illuminates the transparent liquid crystal panel 34. As described above, in the liquid crystal display 30, the transparent liquid crystal panel 34 is illuminated by the light irradiated from the fluorescent lamps 37 a and 37 b, and further reflected on the reflection area 36A of the reflection film 36, and the light irradiated from the fluorescent lamps 38 a and 38 b, further reflected on the surfaces of the mechanical reels 3A to 3E, and made incident onto the non-reflection area 36B. Hence, the area of the liquid crystal display 30, which corresponds to the non-reflection area 36B of the reflection film 36, is an area switched between the transparent state and the opaque state depending on whether or not the liquid crystal is activated. On the other hand, the area of the liquid crystal display 30, which corresponds to the reflection area 36A of the reflection film 36, turns to the opaque state no matter whether or not the liquid crystal is activated.
In the slot machine 13, only the partial area of the display surface of the liquid crystal display 30 is made as the area switched between the transparent state and the opaque state. However, the entire area of the display screen of the liquid crystal display 30 may be made as the area switched between the transparent state and the opaque state. As described above, when the entire area of the liquid crystal display 30 is made as the area switched to the transparent state or the opaque state, the reflection film 36 just needs to be made entirely as the non-reflection area 36B, or the reflection film 36 just needs to be omitted.
FIG. 7 is a block diagram showing an electric construction of the controller 100 of the slot machine 13 with the mechanical reels. As shown in FIG. 7, the controller 100 of the slot machine 13 is a microcomputer, and includes the interface circuit group 102, the input/output bus 104, the CPU 106, the ROM 108, the RAM 110, the communication interface circuit 111, the random number generator 112, a motor drive circuit 120, the speaker drive circuit 122, the hopper drive circuit 124, the display part drive circuit 128, and the display/input controller 140. Note that, since the construction in this case is mostly the same as that in the case of the video reels described in FIG. 4, a description will be made here only of parts different from those in the case of the video reels described in FIG. 4.
To the interface circuit group 102, a reel position detection circuit 46 is connected. The reel position detection circuit 46 is a circuit for detecting rotational positions of the respective mechanical reels 3A to 3E based on pulse signals from reel position detection sensors (not shown). Such detection signals from the reel position detection circuit 46 are also supplied to the interface circuit group 102, converted into predetermined signals by the interface circuit group 102, and then supplied to the input/output bus 104.
The CPU 106 reads out a basic game program and executes the basic game on an occasion that the starting operation of the basic game is received through the start switch 25. The basic game program is programmed so that the respective stepping motors 45A to 45E can be allowed to be driven to rotate all the mechanical reels 3A to 3E, thereby starting to scroll the symbols of the reels 3A to 3E, and the respective stepping motors 45A to 45E can be allowed to then stop driving to stop the rotations of all the mechanical reels 3A to 3E, thereby rearranging the symbols of the reels 3A to 3E, and so that, when a combination of the symbols stopped at that time is shown on the winning line and represents a specific combination for giving the prize, coins corresponding to the specific combination for giving the prize can be paid out.
To the input/output bus 104, the motor drive circuit 120 for driving the stepping motors 45A to 45E is also connected. The CPU 106 controls movements of the stepping motors 45A to 45E through the motor drive circuit 120 in response to an occurrence of a predetermined event.
FIG. 8 is a block diagram showing an electric construction of the display/input controller 140 of the slot machine 13. The display/input controller 140 of the slot machine 13 is a sub-microcomputer for performing image display processing and control for an input from the touch panel 32. The display/input controller 140 includes an interface circuit 142, an input/output bus 144, a CPU 146, a ROM 148, a RAM 150, a VDP 152, a video RAM 154, an image data ROM 156, a drive circuit 158, and a touch panel control circuit 160.
The interface circuit 142 is connected to the input/output bus 144. The image display instruction outputted from the CPU 106 on the above-described controller 100 side is supplied to-the input/output bus 144 through the interface circuit 142. The input/output bus 144 receives and outputs a data signal or an address signal from and to the CPU 146.
To the input/output bus 144, the ROM 148 and the RAM 150 are connected. In the ROM 148, a display control program for creating a drive signal supplied to the liquid crystal display 30 based on the image display instruction from the CPU 106 on the above-described controller 100 side is stored. On the other hand, in the RAM 150, flags, values of variables, and the like for use in the above-described display control program are stored.
To the input/output bus 144, the VDP 152 is also connected. The VDP 152 is a processing device including so-called sprite circuit, screen circuit, pallet circuit, and the like, and capable of performing a variety of processing for displaying an image on the liquid crystal display 30. The VDP 152 is connected to the video RAM 154 for storing image data corresponding to the image display instruction from the CPU 106 on the above-described controller 100 side, and the image data ROM 156 storing a variety of image data including an effect image data as described above, and the like. Moreover, the VDP 152 is also connected to the drive circuit 158 outputting a drive signal for driving the liquid crystal display 30.
The above-described CPU 146 reads out and executes the display control program stored in the ROM 148, and thereby allows the video RAM 154 to store the image data displayed on the liquid crystal display 30 in response to the image display instruction from the CPU 106 on the above-described controller 100 side. The image display instruction includes a variety of image display instructions including a display instruction for the above-described effect image.
The image data ROM 156 stores a variety of image data including the data of the above-described effect image, and the like.
The touch panel control circuit 160 transmits, as an input signal, a signal inputted on the touch panel 32 on the liquid crystal display 30 to the CPU 106 through the input/output bus 144.
FIGS. 9A and 9B are flowcharts showing a series of processing from a start of the conversion of the points data into the credits, to an end thereof, which is executed by the controller 100 of the slot machine 13.
In Step S1, the CPU 106 determines whether or not the slot machine 13 can communicate with the cellular phone 300. When the slot machine 13 ¥can communicate, the CPU 106 moves the processing to Step S2. When the slot machine 13 cannot communicate, the CPU 106 performs the determination of S1 one more times. Specifically, the CPU 106 determines whether or not the wireless transmitting/receiving part 171 provided in the holder 170 can communicate with the cellular phone 300 of the player.
In Step S2, the CPU 106 receives the first authentication data, and moves the processing to Step S3. Specifically, the CPU 106 receives the respective items (the cellular phone ID, the total points data, a server address (an address of the points management server 400), and the type of currency) stored in the first authentication table (refer to FIG. 10) from the cellular phone 300 through the wireless transmitting/receiving part 171, and stores the respective items in the RAM 110.
Here, as described above, the first authentication table shown in FIG. 10 stores the total points acquired by executing the game, the address of the points management server 400, and the type of currency of the cash paid at the time of downloading for each cellular phone ID allocated in the case where the cellular phone 300 downloads the game program from the points management server 400. For example, for a cellular phone ID “A001”, the total points data is “5000”, the server address (the address of the points management server 400) is “aaa”, and the type of currency is “Yen”.
Returning to FIG. 9A, in Step S3, the CPU 106 receives the second authentication data, and moves the processing to Step S4. Specifically, the CPU 106 accesses the points management server 400 based on the address of the points management server 400, which is received through the communication interface circuit 111 in Step S2, receives the respective items (the cellular phone ID, the total points data) stored in the second authentication data table (refer to FIG. 11), and stores the respective items in the RAM 110.
Here, as described above, the second authentication data table shown in FIG. 11 stores the total points acquired by executing the game for each cellular phone ID allocated in the case where the cellular phone 300 downloads the game program from the points management server 400. For example, for the cellular phone ID “A001”, the total points data is “5000”.
Returning to FIG. 9A, in Step S4, the CPU 106 determines whether or not the total points data included in the first authentication data table and the total points data included in the second authentication data table are equal to each other. When both of the total points data are equal to each other, the CPU 106 moves the processing to Step S6. When both of the total points data are not equal to each other, the CPU 106 moves the processing to Step S5. Specifically, the CPU 106 determines whether or not the total points received from the cellular phone 300 and the total points received from the points management server 400 among the total points for the same cellular phone ID, which are stored in the RAM 110, are equal to each other. By performing the processing of Step S4, it is determined whether or not the total points stored in the cellular phone 300 has a correct value. For example, when the determination is made for the cellular phone ID “A001” with reference to FIG. 10 and FIG. 11, the total points thereof stored in both of the tables are 5000, which are equal to each other. Accordingly, it is authenticated that, for the cellular phone ID “A001”, the total points data stored in the cellular phone 300 has a correct value.
In Step S5, the CPU 106 displays an error message screen (refer to FIG. 12), and ends the processing. Here, the error message screen shown in FIG. 12 is a screen displayed when the total points stored in the cellular phone 300 has an erroneous value. On the error message screen, a message to the effect “The stored points data has an error. Access the points management server, and reacquire correct points.” is displayed.
In Step S6, the CPU 106 receives the conversion rate data corresponding to the data on the type of currency, and moves the processing to Step S7. Specifically, the CPU 106 transmits, to the conversion rate management server 500, such currency type data received from the cellular phone 300, receives the conversion rate corresponding to the currency type data from the conversion rate table (refer to FIG. 13) stored by the conversion rate management server 500, and stores the conversion rate in the RAM 110. For example, when the cellular phone ID is “A001”, the type of currency, which is received from the cellular phone 300, is “Yen”, and the CPU 106 receives “10” as the conversion rate with reference to the conversion rate table of FIG. 13.
Here, in the conversion rate table shown in FIG. 13, values of points data necessary to obtain one credit after conversion are stored. For example, when the type of currency is “Yen”, 10 points are necessary to obtain one credit after the conversion.
Returning to FIG. 9A, in Step S7, the CPU 106 updates the conversion rate data, and moves the processing to Step S8. Specifically, the CPU 106 overwrites the received conversion rate data onto the conversion rate data stored in the RAM 110. In such a way, it is made possible to convert the points data into data on the number of credits by the conversion rate according to the type of currency paid when the cellular phone 300 downloads the game.
In Step S8, the CPU 106 displays a conversion points input screen (refer to FIG. 14), and moves the processing to Step S9.
Here, the conversion points input screen shown in FIG. 14 is a screen for allowing the player to enter the points to be converted into the number of credits. The conversion points input screen is displayed on the liquid crystal display 30 by the CPU 106 through the display/input controller 140. When the conversion points input screen is displayed, the player can enter the conversion points by operating a ten key 201 by hand 200, and can decide the conversion points by operating a conversion decision switch 203 thereby. Note that the player can clear the entered conversion points by operating a clear switch 202 by hand 200.
Moreover, the CPU 106 displays the points necessary to obtain one credit after the conversion and the maximum convertible points (the total points stored by the cellular phone 300). For example, in the case of a cellular phone 300 with the cellular phone ID “A001”, as described above, the points necessary to obtain one credit after the conversion are “10”, and the maximum convertible points are “5000”.
Returning to FIG. 9A, in Step S9, the CPU 106 receives the input of the conversion points, and moves the processing to Step S10. Specifically, the CPU 106 receives the input of the conversion points through the display/input controller 140 in such a manner that the ten key 201 provided on the liquid crystal display 30 is operated by hand 200 on the conversion points input screen (refer to FIG. 14).
In Step S10, the CPU 106 determines whether or not the conversion decision switch 203 is operated, moves the processing to Step S11 when such an operation is performed, and performs the determination of S10 one more time when the operation is not performed. Specifically, the CPU 106 determines whether or not the conversion decision switch 203 provided on the liquid crystal display 30 is operated on the conversion points input screen (refer to FIG. 14) by hand 200. When the conversion decision switch 203 is operated, the conversion points is decided, and the inputted conversion points data is stored in the RAM 110.
In Step S11, the CPU 106 determines whether or not a value of the inputted conversion points data is the maximum convertible points or less. When the value is the maximum convertible points or less, the CPU 106 moves the processing to Step S12. When the value is not the maximum convertible points or less, the CPU 106 moves the processing to Step S9. Specifically, the CPU 106 compares a value of the total points data received from the points management server 400, which is the maximum convertible points data, with a value of the inputted conversion points data.
In Step S12, the CPU 106 makes a request to transmit the conversion points data, and moves the processing to Step S13. Specifically, the CPU 106 transmits, to the cellular phone 300, data requesting transmission of the conversion points data stored in the RAM 110 in Step S10.
In Step S13, the CPU 106 receives the conversion points data, and moves the processing to Step S14. Specifically, the CPU 106 receives the requested conversion points data from the cellular phone 300, and stores the received conversion points data in the RAM 110. Moreover, the CPU 106 transmits, to the cellular phone 300, data for subtracting the conversion points from the points stored by the cellular phone 300.
In Step S14, the CPU 106 converts the received points data into number-of-credits data based on the updated conversion rate data. Specifically, the CPU 106 converts the points data received in Step S13 into the number-of-credits data based on the conversion rate data updated in Step S7. For example, “1000 points” are converted on the conversion points input screen shown in FIG. 14, “100 credits” are added since “10” points are necessary per credit. The CPU 106 stores the converted number-of-credits data in the RAM 110, adds the converted number-of-credits data to the number-of-credits data already stored in the RAM 110, and displays the number-of-credits data thus obtained on the number-of-credits display part 49. Thereafter, the CPU 106 ends this processing.
Note that the conversion rate table shown in FIG. 13 is stored in the conversion rate management server 500, and the conversion rate changes with time for each type of currency. The conversion rate is determined based on an exchange rate that changes in real time. For example, with regard to “Dollar” and “Yen”, it is supposed that the conversion points per credit is “10 points”, and that each of “100 yen” and “one dollar (100 yen per dollar)” is necessary in order to purchase 10 points. Moreover, it is supposed that one dollar becomes equivalent to 120 yen owing to subsequent fluctuations of the exchange rate. Then, 100 yen become equivalent to 0.83 dollars, and specifically, 100 yen which have previously been equivalent to one dollar become equivalent to 0.83 dollars. Accordingly, the value of the dollar rises. Hence, in the conversion rate management server 500, the conversion points of “Dollar” per one credit is obtained as “8.3 points” from a multiplication of 10 points by 0.83 based on the current exchange rate.
In such a way, the current exchange rate is reflected in the conversion rate table. Hence, also in the slot machine 13, the points data can be converted into the number-of-credits data based on the conversion rate data on which the current exchange rate is reflected.
Note that the conversion rate management server 500 receives the exchange rate changed in real time from a predetermined server (not shown), and stores the exchange rate.
Moreover, the CPU 106 can change the conversion rate by a change of the conversion points per credit for a specific type of currency, which is a different method from the change of the conversion rate based on the exchange rate.
For example, for “Yen” (the specific type of currency), the CPU 106 changes the conversion points per credit from “10 points,” to “15 points”, and thereby converts the points data for “Dollar”, “Euro”, and the like, which correspond to “15 points”, into the number-of-credits data based on the current exchange rate.
Note that the conversion rate data may be stored in advance in the conversion rate table for each type of currency.
As described above, in this embodiment, the player transmits the points data stored in the cellular phone 300 to the slot machine 13, thus making it possible to convert the points data into the credits to play the basic game. Accordingly, the player can purchase the credits easily. Therefore, the fun of the game is enhanced.
Moreover, the total points acquired by executing the game is stored in the points management server 400, and when the points data is converted into the credits, the points data can be converted after it is authenticated that the total points stored by the cellular phone 300 have a correct value. Accordingly, for example, undesirable situations such as the total points being incorrectly rewritten can be avoided.
Furthermore, the points data can be converted into the credits while reflecting therein the exchange rate changed in real time for each type of currency of the cash paid when the game is downloaded. Accordingly, the variety of options for selecting the type of currency for downloading the game is widened. Therefore, the fun of the game is enhanced.
Still further, the data transfer between the cellular phone 300 and the slot machine 13 is performed by using an IC card (IC chip) of a non-contact mode, and thus communication speed is significantly accelerated as compared with the case of making the communication through a cellular phone network. Accordingly, the player can purchase the credits easily, and the fun of the game is enhanced.
The description has been made above of the embodiment of the game system according to the present invention; however, the embodiment merely illustrates a specific example, and does not particularly limit the present invention. It is possible to appropriately change specific configurations of each means and the like. Moreover, the effects described in the embodiment of the present invention are merely a list of the most suitable effects generated from the present invention, and the effects derived from the present invention are not limited to the effects described in the embodiment of the present invention.
For example, though the points can be acquired by executing the game played offline after the cellular phone 300 downloads the game in this embodiment, the points may be acquired by playing an online game.
Moreover, the data transfer between the cellular phone 300 of the player and the slot machine 13 may be performed through the cellular phone network (not shown). Furthermore, an external connection terminal (not shown) may be provided in the slot machine 13 (not shown), and connected to the cellular phone 300 of the player.
