  The present invention relates to a slot machine that can win a winning medal by stopping a plurality of rotating reels (rotating drums) so that symbols, symbols, and the like attached to each reel are in a predetermined arrangement. In particular, the present invention relates to a slot machine capable of displaying arbitrary content information and the like over the entire front panel of the slot machine with a simple and inexpensive structure.

Generally, in a slot machine, when a player inserts a game medal and operates a start lever, a plurality of reels (generally three) rotate and a plurality of symbols drawn on the surface of the reel move at a high speed, and then When the player operates the stop button corresponding to each reel, the rotation of each reel is stopped, and a plurality of symbols drawn on the surface of each reel are stopped and displayed.
If the combination of symbols that are stopped and displayed is a predetermined combination, a game medal as a prize is paid out, and that the combination of symbols that are displayed and stopped is a predetermined special winning mode. As a starting condition, a special game (such as a bonus game) advantageous to the player as compared with a general game is played.

By the way, in this type of slot machine, there is a type that includes a display device for performing an effect display relating to a game separately from a reel. Such an effect display device is configured by a dot display device, a liquid crystal display device, or the like, and displays a demonstration of a game in the slot machine, an effect image accompanying the progress of the game, and the like.
FIG. 9 is an external perspective view showing an example of a slot machine (slot machine with a display device) provided with a conventional display device for presentation.
As shown in the figure, a conventional slot machine DSM with a display device includes a housing 100 and a front door 200 that can be opened and closed.

The casing 100 has a vertically long rectangular parallelepiped shape, and a reel, a medal payout mechanism, a control device, and the like are accommodated therein (not shown).
The front door 200 includes a front panel 210 capable of displaying reel symbols and the like, an operation unit 220 having a start lever, the character display unit 230 and the payout display unit 240, which are the aforementioned display devices, and a medal payout unit. 250 (medal payout slot 251 and medal tray 252).
Three vertically long display windows 212 (212a, 212b, 212c) are provided on the front surface of the front panel 210, and reels 213 (213a, 213b, 213c) are disposed behind the display window 212, respectively. The symbols drawn on the outer peripheral surface of each reel 213 are visible through the display window 212.
In addition to the three vertically long display windows, the display window 212 may be composed of, for example, one horizontally long display window that is large enough to visually recognize the three reels 213 at the same time.

On the front left side of the front panel 210, a credit indicator 215 that displays the number of medals (credits) that can be played and a count indicator 214 that displays the number of winning games are arranged. On the right side, a payout indicator 216 for displaying the number of payouts corresponding to “winning” is arranged.
The count display 214, the credit display 215, and the payout display 216 are each configured with, for example, a 7-segment LED.
In the operation unit 220, a start lever 221 for starting rotation of the three reels 213, a stop button 222 (222a, 222b, 222c) for stopping each of the rotating reels, and one game are input. A medal BET switch 223 for determining the number of medals and a medal slot 224 are provided.

The character display unit 230 includes light emitting diodes (LEDs) arranged in a matrix, so that an effect display by a character related to a game is performed.
Here, as a production | presentation character, there exists a thing shown to FIG. 10 (a), (b), (c), for example.
FIG. 10A shows a “gang” displayed at the time of a small role, FIG. 10B shows a “kiss mark” displayed at the time of a bonus, and FIG. 10C shows a button. This is an “electrocardiogram waveform” displayed when the timing of pressing is successful.
In addition to the light emitting diode, the character display 230 includes a liquid crystal display device.

The payout display 240 is composed of a liquid crystal display device, for example, and displays a “winning” mode (for example, 15 medals in the case of “777”) in the case of a regular bonus or a big bonus. .
Note that the payout indicator 240 may be formed of a light emitting diode or the like instead of the liquid crystal display device.
From the speakers 241a and 241b arranged on the left and right of the payout display 240, effects such as announcements at the time of “bonus game start”, music, sound effects, and the like are transmitted.

Here, regarding the effect display during the game in the slot machine provided with the display device for the effect as described above, the following proposals are further made.
For example, in Patent Document 1, between a fluctuation display means (reel) and an effect image display means (liquid crystal display device) for displaying an effect image arranged at a predetermined angle with the fluctuation display means, An arrangement in which half mirrors are arranged at a predetermined inclination angle has been proposed.
With such a configuration, it is possible to display the effect image displayed on the effect image display unit superimposed on the design displayed on the variation display unit by the half mirror.

Japanese Patent Application Laid-Open No. 2004-228620 proposes a greatly enlarged display screen in a gaming machine such as a slot machine.

Larger effects can be displayed than the conventional display devices for effects (see FIG. 9).

JP 2002-113150 A (page 3-4, FIG. 2) JP-A-6-35066 (page 2-3, FIG. 1)

However, the slot machine provided with the conventional display device for presentation as described above has the following problems.
First, in the slot machine with a display device shown in FIG. 9, the positions of the character display and the payout display are fixed, and the layout and size of the displayed characters / characters / numbers are extremely small. Only a certain pattern display can be performed.
In addition, since the count display 214, the credit display 215, and the payout display 216 are composed of 7 segments, only characters and numbers are displayed, and it cannot be said that the display is attractive.

In addition, the proposal described in Patent Document 1 requires an expensive and large-sized liquid crystal display device that can cover the entire plurality of reels, and the price of the slot machine may increase significantly.
Furthermore, in the proposal described in Patent Document 2, all of the slot machine including the reel is displayed as a moving image, and this conflicts with the regulation of the current law that “the reel must be made of hardware such as resin”. In addition, game machines that do not have mechanical reels and are all displayed as video images can no longer be called slot machines. In particular, this is an idea that cannot be adopted at game halls in Japan. There wasn't.

  The present invention has been proposed in order to solve the conventional problems as described above, and the entire front panel of the slot machine can be obtained without changing the configuration of an existing slot machine having a mechanical reel. Any content information can be displayed over a wide range, the design freedom for characters, letters, numbers, etc. on the front panel can be increased, and new and attractive production display etc. can be performed, And it aims at provision of the slot machine which the production means can manufacture cheaply.

  To achieve the above object, a slot machine of the present invention is a slot machine comprising a plurality of reels that are rotationally driven by a start operation and a plurality of stop buttons provided corresponding to the plurality of reels. The screen means (projection / transmission plate 40 in FIGS. 2 and 3) arranged in front of the screen and the content information projection means (in FIGS. 2 and 4) for projecting content information related to the game from the front side of the screen means. Content transmitter 32 and reflecting mirror 33), and the screen means includes at least a reel-facing portion (the liquid crystal panel portion 43 in FIGS. 2 and 3) which is a portion facing the outer peripheral surface of the plurality of reels (213). It is configured by a transmission / non-transmission controllable member that can be controlled to a transmission state or an opaque state.

The above configuration is illustrated in FIGS. 2, 3, and 4, for example.
In this way, as shown in FIG. 3A, a wide area can be secured as the screen means (projection / transmission plate 40). Accordingly, various designs (characters, numbers, characters, etc.) can be projected from the content information projection means (content transmitter 32) onto the screen means with a large degree of freedom (size, position, mode, etc. of characters etc.). The image projected on the screen means may be either a still image or a moving image.

In the slot machine of the present invention, the transmission / non-transmission controllable member is constituted by a liquid crystal display panel (liquid crystal panel unit 43).
The above configuration is illustrated in FIGS. 2 and 3, for example.
In this way, by controlling the voltage applied to the liquid crystal display panel, the liquid crystal display panel can be transmitted or not transmitted (for example, white). Therefore, when the liquid crystal is transmitted, it is possible to visually recognize the design of the reel as shown in FIG. 3B. When the liquid crystal is not transmitted, as shown in FIG. For example, the pre-game screen 23 can be displayed by making the entire board 40 opaque (white screen).

The slot machine of the present invention is configured to display content information projected from the content information projection means (content transmitter 32) on a portion other than the reel-facing portion (screen portion 41 shown in FIG. 3A). It is as.
When the above configuration is illustrated, for example, as shown in FIGS. 3A and 6, a portion other than the reel-facing portion (screen portion 41 in FIG. 3A) is a wide area. Various designs (characters, numbers, characters, etc.) can be projected from the information projecting means (contents transmitter 32) onto a portion other than the reel-facing portion with a large degree of freedom (size, position and mode of characters etc.).

Further, the slot machine of the present invention has a reel-facing portion (liquid crystal panel portion 43) in which the screen means (projection / transmission plate 40 in FIG. 3) is controlled to be non-transmissive, and portions other than the reel-facing portion (FIG. 3A). The content information projected from the content information projection means (content transmitter 32) is displayed on both screen portions 41).
The above configuration is illustrated in FIGS. 3 and 5, for example.
In this way, as shown in FIG. 5, both the reel facing portion (liquid crystal panel portion 43) and the portion other than the reel facing portion (screen portion 41 in FIG. 3A) are made opaque (white screen). Thus, for example, the pre-game start screen 23 can be displayed. As a result, it is possible to project and display an arbitrary still image or moving image on a wide area over the entire surface of the front panel, and it is possible to provide a novel effect display and the like that have not been possible in the past.

Further, the slot machine of the present invention is configured to include a side light shielding plate (side light shielding plate 21 shown in FIGS. 1 and 2) covering the front side surface of the screen means (projection / transmission plate 40 in FIG. 3).
By providing such a side light-shielding plate, it is possible to block and prevent the entry of extraneous light to the surface of the projection / transmission plate, and to display a clear image on the screen means. As a result, it is possible to perform an attractive effect or the like with a brighter and clearer projected image, and to prevent the emission of light to the outside.

According to the present invention, since it is possible to secure a wide area as the screen means, various designs (characters, numbers, characters, etc.) can be obtained from the content information projection means with a large degree of freedom (size, position, character, etc.). In a mode etc.).
Further, by controlling the voltage applied to the liquid crystal display device constituting the screen means, it is possible to transmit the liquid crystal or to make it non-transparent (for example, white). It becomes possible to visually recognize the design of the reel, and when the liquid crystal is made impermeable, the entire screen means is made impermeable (white screen), and arbitrary content information can be displayed.

As a result, since the part other than the reel facing part becomes a wide area, various designs (characters, numbers, characters, etc.) from the content information projection means with a large degree of freedom (size, position, aspect, etc. of the characters, etc.) Can be projected on parts other than the reel facing part.
Further, both the reel-facing portion and the portions other than the reel-facing portion are made opaque (white screen), so that, for example, a pre-game start screen can be displayed on the entire surface of the slot machine full surface panel.
Thus, according to the slot machine of the present invention, it becomes possible to display arbitrary content information etc. over the entire front panel of the slot machine with a simple and inexpensive structure such as a projector or a liquid crystal panel. It is possible to realize a slot machine that can display a novel and attractive presentation that does not exist in the past.
