Therefore, the medal insertion slot 6, the one-bet button 7, the max-bet button 8, the adjustment button 9, the start lever 10, the stop button unit 14, the return button 15, the performance button 18 and the numerical keypad 19 are likely to need to be replaced or repaired.

In this case, if the control panel case 601 is formed integrally with the front door 3, the front door 3 needs to be removed from the cabinet 2. This makes the work of repair complicated.

In contrast, with the present embodiment, the components constituting the control panel module 600 are accommodated in the control panel case 601, and this control panel case 601 is removably attached to the front door 3, and therefore it is possible to remove the control panel module 600 from the front door 3.

By this means, when the components constituting the control panel module 600 have to be replaced or repaired, it is not necessary to remove the front door 3 from the cabinet 2, but merely the control panel module 600 is removed from the front door 3, and therefore it is possible to improve the efficiency of the work of repair.

In addition, with the present embodiment, the control panel module 600 further includes the control panel bracket 602 on the rear surface side of the performance button bracket 603 that convers the rear surface side of the performance button 18.

That is, the control panel bracket 602 that covers the performance button bracket 603 is provided on the rear surface side of the control panel module 600, so that it is possible to reliably protect the performance button 18 and the other parts.

Then, this control panel bracket 602 serves as an earth. By this means, it is possible to improve the safety in the removal of the control panel module 600 from the front door 3.

To be more specific, each component of the control panel module 600 is electrically driven. Therefore, each component may radiate electromagnetic waves. Here, the control panel bracket 602 serves as an earth, so that it is possible to prevent improper operation due to the electromagnetic waves.

As described above, with the present embodiment, it is possible to improve the safety in the removal of the control panel module 600 from the front door 3.

Next, the stop button unit 14 according to the present embodiment will be described with reference to FIGS. 3A to 3F.

Here, FIG. 3C shows the stop button unit 14 from the front side to the back side, assuming that the side on which the player sits at the game machine 1 is the front side.

As shown in FIG. 3A to FIG. 3C, the stop button unit 14 according to the present embodiment includes the left stop button 11, the middle stop button 12 and the right stop button 13 which can be operated by the player.

In addition, the stop button unit 14 includes a stop button unit case 700 that accommodates the left stop button 11, the middle stop button 12 and the right stop button 13.

This stop button unit case 700 has a left stop button accommodation part 701, a middle stop button accommodation part 702 and a right stop button accommodation part 703 to accommodate the left stop button 11, the middle stop button 12 and the right stop button 13, respectively.

In this way, with the present embodiment, the middle stop button light source area 712 has the first middle stop button LED 712a, the second middle stop button LED 712b, the third middle stop button LED 712c, and the fourth middle stop button LED 712d. By using these middle stop button LEDs, it is possible to provide a variety of performances such that the middle stop button LEDs are lit at a time and at different times. Here, the first stop button LED 712a, the second stop button LED 712b, the third stop button LED 712c, and the fourth stop button LED 712d are equivalent to “plurality of light sources” recited in the appended claims.

A stop button unit bracket 720 is provided on the rear surface side of the light source board 710. This stop button unit bracket 720 is formed by a nonconductive member. Therefore, the stop button unit bracket 720 can prevent improper operation due to the static electricity discharged from the other parts.

Meanwhile, a front cover 730 is provided on the front surface side of the stop button unit case 700. This front side cover 730 has a left stop button insertion hole 731, a middle stop button insertion hole 732 and a right stop button insertion hole 733 into which the left stop button 11, the middle stop button 12 and the right stop button 13 are inserted, respectively.

Next, the configuration of the left stop button 11, the middle stop button 12 and the right stop button 13 according to the present embodiment will be described with reference to FIGS. 3D to 3F, as well as FIGS. 3A to 3C.

FIG. 3D is a schematic cross-sectional view showing the stop button unit 14 shown in FIG. 3B, taken along line I-I′; FIG. 3E is a back perspective view showing the middle stop button 12 according to one embodiment of the present invention; and FIG. 3F is a back view showing the middle stop button 12 according to one embodiment of the present invention.

Here, with the present embodiment, the left stop button 11, the middle stop button 12 and the right stop button 13 are located in the different positions in the stop button unit 14, but have the same configuration as each other. Therefore, the middle stop button 12 is described and overlapping descriptions will be omitted.

As shown in FIGS. 3A to 3F, the middle stop button 12 according to the present embodiment includes a middle top button lens body 742. The middle stop button 12 also includes a middle stop button operation part 752 that can be pushed directly by the player, a middle stop button spring 762 that allows the middle stop button lens body 742 and the middle stop button operation part 752 to reciprocate, and a middle stop button sensor 772 that detects the middle stop button operation part 752 being pushed by the player. Here, the stop button operation part 752 is equivalent to “operation part” recited in the appended claims.

Here, with the present embodiment, the middle stop button spring 762 is not limited as long as it allows the middle stop button operation part 752 to reciprocate by the pushing operation of the player.

This middle stop button lens body 742 includes a cylindrical part 782 that forms the outer boundary of the middle stop button lens body 742, and a conical part 792 provided in the cylindrical part 782. Here, the cylindrical part 782 and the conical part 792 of the middle stop button lens body 742 are equivalent to “hollow part” and “light transmissive part” recited in the appended claims, respectively.

The cylindrical part 782 is provided along the front-to-back direction of the game machine 1. With the present embodiment, a light shielding process is applied to the cylindrical part 782.

By this means, it is possible to prevent the light incident on the middle stop button lens body 742 from leaking from the middle stop button lens body 742.

A middle stop button sensor 772 is provided in the cylindrical part 782. Therefore, unless the light shielding process is applied to the cylindrical part 782, the light incident on the middle stop button lens body 742 leaks from the middle stop button lens body 742, so that the middle stop button sensor 772 may be reacted.

Accordingly, for example, unless the light shielding process is applied to the cylindrical part 782, the middle stop button sensor 772 reacts with the light leaking from the cylindrical part 782 despite that the middle stop button operation part 752 is not pushed by the player, and therefore determines that the middle stop button operation part 752 is pushed.

However, with the present embodiment, the light shielding process is applied to the cylindrical part 782 as described above, to prevent the light from leaking from the middle stop button lens body 742. As a result, it is possible to prevent a detection error of the middle stop button sensor 772.

The conical part 792 of the middle stop button lens body 742 is accommodated in the cylindrical part 782 and provided along the front-to-back direction of the game machine 1. Then, the conical part 792 is formed to reduce its diameter from the front surface side to the rear surface side.

That is, the inner surface of the conical part 792 tapers. In addition, the inner surface of the conical part 792 includes a multi-faceted lens.

With the present embodiment, a number of small hemispheres are formed in the inner surface of the conical part 792 from the front surface side to the rear surface side. That is, the inner surface of the conical part 792 serves to diffuse light and control the light efficiency.

In addition, with the present embodiment, the conical part 792 is formed in the cylindrical part 782.

Therefore, a space is provided between the cylindrical part 782 and the conical part 792, which gradually increases in size from the front side to the back side. Then, a shielding part is formed in the space.

With the present embodiment, the shielding part is formed of a plate.

This shielding part is non-translucent. One LED is provided in each space formed by the shielding part. By this means, the light from each LED is collected and emitted to the lens body without interference with another light. That is, the entire stop button is not lit, but it is possible to light the portion irradiated with the light from each LED.

Then, as described above, the light is diffused on the lens surface, and the lens body is irradiated with the diffused light, so that it is possible to light the entire stop button.

That is, the light efficiency is controlled by using the LEDs with the same capability. Therefore, by lighting the LEDs at different times, it is possible to show the player as if the light is rotating.

A left stop button operation part is formed by a permeable member.

Here, although with the present embodiment, the CGROM 423 stores the palette data in an uncompressed way, it is by no means limiting. Part of the pallet data may be compressed. In addition, to compress movies, various compression technologies, such as MPEG 4 are applicable.

The crystal oscillator 424 is provided to output a pulse signal (V-blank interrupt signal> to the video display processor 421 every “ 1/60 seconds (about 16.6 ms).” Also the video display processor 421 divides the frequency of the pulse signal to generate a system clock for the control and a synchronizing signal to synchronize with the LC display device 41. Then, upon detecting the V-blank interrupt signal, the video display processor 421 outputs a performance timing information signal to the LC control CPU 422a at a predetermined time, based on the V-blank interrupt signal.

An SRAM (Static Random Access Memory) may be used as the VRAM 425. Here, the SRAM may be a readable and writable memory and a sort of volatile memory for temporarily storing data. Since the VRAM 425 includes a SRAM, it is possible to realize the high-speed processing to write and read image data. In addition, the VRAM 425 has a memory map constituted of an optional area, a display list area 1, a display list area 2, a frame buffer area 1 and a frame buffer area 2.

FIG. 6 shows the performance determination table provided in the sub-ROM 414. The sub-control board 400 determines various performances by using the performance determination table and controls the performances. To be more specific, the performance determination table defines “performance No.” and the performance contents corresponding to the performance numbers.

With the present embodiment, for example, “performance No. 068” corresponds to a win sure performance. This win sure performance is presented when it is determined that the game will progress to a bonus preparation state or a bonus state. When the win sure performance is presented, the lighting is controlled in the special lighting mode such that the start lever performance lamp 42, the stop button performance lamp and the performance button lamp (not shown) are repeatedly lit, blinked and turned off.

Therefore, the sub-control board 400 can control the information that is controlled also in the main control board 300. Then, when the processing in the step S404 ends, the step moves to step S405.

In the step S405, the sub-CPU 412 performs command analysis processing, which will be described later with reference to FIG. 13. This processing includes the processing corresponding to the command inputted from the I/F circuit 305 in the main control board 300 to the I/F circuit 411. Then, when the processing in the step S405, the step moves to the step S402.

Next, the lamp control task will be described with reference to FIG. 12.

In step S601, the sub-CPU 412 performs initialization processing. To be more specific, the sub-CPU 412 performs the processing for initializing data on the lamps. Then, when the processing in the step S601 ends, the step moves to step S602.

In the step S602, the sub-CPU 412 performs processing for executing the image control task. This processing includes the processing for analyzing the image data determined in the processing for determining image data in step S405-4 described later (see FIG. 13), and outputting a predetermined signal to the image control board 420, based on the result of the analysis. Then, when the processing in the step S602 ends, the step moves to step S603.

In the step S603, the sub-CPU 412 performs processing for analyzing lamp data. This processing includes processing for analyzing the lamp data determined in the lamp data determination processing of step S405-2 described later (see FIG. 13). Then, when the processing in the step S603 ends, the step moves to step S604.

In the step S604, the sub-CPU 412 performs lamp control processing. To be more specific, the sub-CPU 412 performs the processing for controlling the lighting of the side lamp 5, the performance lamp 22, the stop operation order display lamp 30, and the start lever performance lamp 42, based on the result of the analysis of the processing in the step S603. Then, when the processing in the step S604 ends, the step moves to step S602.

Next, processing for analyzing a command will be described with reference to FIG. 13. Here, FIG. 13 shows a sub-routine of command analysis processing.

In step S405-1, the sub-CPU 412 performs processing for determining performance contents. This processing includes processing for determining various performance contents, based on the received command. Then, when the processing in the step S405-1 ends, the step moves to the step S405-2.

In the step S405-2, the sub-CPU 412 performs processing for determining lamp data. To be more specific, the sub-CPU 412 performs the processing for determining the lamp data corresponding to the performance content determined by the processing in the step S405-1. Then, when the processing in the step S405-2 ends, the step moves to the step S405-3.

With the present embodiment, in order to indicate that the middle stop button 12 is enabled, the sub-CPU 412 lights the first middle stop button LED 712a. The same applies to left stop button 11 and the right stop button 13. Here, with the present embodiment, only the first middle stop button LED 712a is lit in order to indicate that the middle stop button 12 is enabled, but it is by no means limiting. The second middle stop button LED 712b, the third middle stop button LED 712c, and the fourth middle stop button LED 712d may be lit as well as the first middle stop button LED 712a.

Then, when the player pushes the middle stop button 12, the sub-CPU 412 turns off the first middle stop button LED 712a. This allows the player to know whether or not the first middle stop button LED 712a is enabled.

Moreover, with the present embodiment, the sub-CPU 412 lights the second middle stop button LED 712b, the third middle stop button LED 712c, and the fourth middle stop button LED 712d in sequence, as one of the performance display modes with the middle stop button 12 to provide the player with a hope for a jackpot.

In this case, the sub-CPU 412 lights the second middle stop button LED 712b, and then, when lighting the third middle stop button LED 712c, the sub-CPU 412 turns off the second middle stop button LED 712b. Likewise, when lighting the fourth middle stop button LED 712d, the sub-CPU turns off the third middle stop button LED 712c.

That is, the sub-CPU 412 performs the control to repeatedly light and turn off the second middle stop button LED 712b, the third middle stop button LED 712c, and the fourth middle stop button LED 712d in sequence.

In addition, while the sub-CPU 412 repeatedly lights and turns off the second middle stop button LED 712b, the third middle stop button LED 712c and the fourth middle stop button LED 712d in sequence, the sub-CPU 412 lights the first middle stop button LED 712a as the stop button available display in order to indicate that the middle stop button 12 is enabled, and then, when the middle stop button 12 is pushed by the player, the sub-CPU 412 turns off the first middle stop button LED 712a.

Moreover, when the middle stop button 12 is pushed by the player, the sub-CPU 412 also turns off the second middle stop button LED 712b, the third middle stop button LED 712c and the fourth middle stop button LED 712d.

Here, with the present embodiment, when the middle stop button 12 is pushed by the player, the sub-CPU 412 turns off the second middle stop button LED 712b, the third middle stop button LED 712c, and the fourth middle stop button LED 712d. However, it is by no means limiting, but the second middle stop button LED 712b, the third middle stop button LED 712c, and the fourth middle stop button LED 712d may be continuously lit in sequence.

Moreover, with the present embodiment, the sub-CPU 412 sequentially lights the LEDs, as one of the performance display modes with the middle stop button 12 to provide the player with a hope for a jackpot. However, it is by no means limiting, but the sub-CPU 412 may control the lighting of the LEDs in a special lighting mode such that the LEDs are repeatedly lit, blinked and turned off as one of the performance display modes for a win sure performance.

To be more specific, during the win sure performance, the sub-CPU 412 lights the second middle stop button LED 712b, the third middle stop button LED 712c and the fourth middle stop button LED 712d in sequence. Here, this win sure performance is provided when it is determined that the game will progress to a bonus preparation state or bonus state.

In the step S405-3, the sub-CPU 412 performs processing for determining sound data. To be more specific, the sub-CPU 412 performs the processing for determining the sound data corresponding to the performance content determined by the processing in the step S405-1. Then, when the processing in the step S405-3 ends, the step moves to step S405-4.

In the step S405-4, the sub-CPU 412 performs processing for determining image data. To be more specific, the sub-CPU 412 performs the processing for determining the image data corresponding to the performance content determined by the processing in the step S405-1. Then, when the processing in the step S405-4 ends, the command analysis processing is terminated, and the step moves to the step S402 in the main board communication task (see FIG. 11).

As described above, the stop button unit 14 according to the present embodiment includes the left stop button 11, the middle stop button 12 and the right stop button each having a plurality of light sources.

Then, with the present embodiment, in order to indicate that the middle stop button 12 is enabled, the sub-CPU 412 lights the first middle stop button LED 712a as the stop button available display. The same applies to the left stop button 11 and the right stop button 13.

Meanwhile, during the performance display, the sub-CPU 412 lights the second middle stop button LED 712b, the third middle stop button LED 712c, and the fourth middle stop button LED 712d in sequence. By this means, with the present embodiment, it is possible to provide a variety of performances with the middle stop button 12, and therefore to improve the effects of the performances.

Here, with the present embodiment, the left reel 17a, the middle reel 17b and the right reel 17c serve as a plurality of symbol arrays, and the reel unit 17d serves as a symbol display device. However, it is by no means limiting, but an image output device such as an LC display device may serve as the symbol display device, instead of the left reel 17a, the middle reel 17b, the right reel 17c and the reel unit 17d.

Moreover, with the present embodiment, although the start lever 10 is employed as a spin start device, it is by no means limiting, but, for example, a start button is applicable, instead of the start lever 10.

Moreover, with the present embodiment, the first middle stop button LED 712a, the second middle stop button LED 712b, the third middle top button LED 712c, and the fourth middle stop button LED 712d serve as a plurality of light sources. However, it is by no means limiting.

Furthermore, with the present embodiment, the stop button unit 14 is used as an example of “operation device.” However, it is by no means limiting, but the present invention is applicable to any operation devices that can be operated by the player, such as the above-described start lever (start button) and a touch panel, which can display an image mimicking buttons. In addition, with the present embodiment, it has been described that the present invention is applied to a slot machine. However, it is by no means limiting, but the present invention may be applicable to a pachinko machine, a mahjong ball game machine, and an arrange ball game machine.

For example, the above-described “operation device” may be applicable to a video game device. Here, a video game device 800 having the operation device according to the present invention will be described with reference to FIG. 14.

As shown in FIG. 14, the video game device 800 can perform a card game (e.g. poker, and baccarat), and a slot machine game. This video game device 800 includes an insertion slot 801 into which a card or paper money is inserted; a first image display device 802 that can display game images of a card game, a slot machine game and so forth; an operation buttons 803 that can start and stop the game, and select various images; a payout slot 804 from which a prize such as a card or paper money can be paid out; and a second image display device 805 that can display a performance image associated with the game.

In the video game device 800 with the above-described configuration, it is possible to perform a card game, a slot machine game and so forth by inserting a card or paper money into the insertion slot 801 in the same way as in the above-described game machine 1.

Here, the flow of a video game performed by the video game device 800 will be described in two cases: when the video game is a card game; and when the video game is a slot machine game.

First, one case in which the video game is a card game (e.g. poker game) will be described. The video game device 800 is configured to perform a card game by the player. The card game can be performed by inserting a card and so forth into the insertion slot 801, and then operating the operation lever 803a.

To be more specific, when the operation button 803a is operated, the first image display device 802 displays a plurality of rear surface images that imitate the rear surfaces of playing cards, and then, when any of the operation buttons 803b is operated, the rear surface image corresponding to the operation button 803b is inverted and a face card image representing a picture is displayed. Then, in a case in which the plurality of face card images constitute a specific condition (e.g. one pair), a prize corresponding to this specific condition is paid out from the payout slot 804.

Next, the other case in which the game performed by the video game device 800 is a slot machine game will be described. The video game device 800 is configured to perform a slot machine game by the player. The slot machine game can be performed by inserting a card and so forth into the insertion slot 801, and then operating the operation button 803a, in the same way as in the case of a card game.

To be more specific, when the player operates the operation lever 803a, the plurality of reel images stopped and displayed on the first image display device 802 are rotated at a time, and, when the player operates the operation buttons 803b, the reel images corresponding to the operation buttons 803b can be stopped. Then, when the combination of the stopped symbols represents a specific condition, a prize corresponding to the specific condition is paid out from the payout slot 804.

In the video game device 800 with the above-described configuration, a plurality of LEDs can be built in the operation button 603a and the operation buttons 603b, like the middle stop button 12.

In this case, when a predetermined condition is met, for example, when it is previously determined that a card game or a slot game is provided with a specific condition, it is possible to light and blink a plurality of LEDs. As a result, it is possible to improve the performance effects in the same way as in the game machine 1.

Although the preferred embodiment has been explained, it is by no means limiting, it will be appreciated that various modifications and alterations are possible without departing from the scope of the invention.
