The third effective line display unit 34 is notified by lighting or the like when a pair of diagonal lines (downward right line and upward right line) of the combination lines is activated. Then, when the combination line that has been activated, that is, the pattern stops on the activated line in a predetermined combination, a prize is awarded, and a predetermined medal pay-on process, a process for shifting to a specific game, and the like are executed.

<Reel tape configuration>
FIG. 6 is a development view of a strip-shaped reel tape constituting each reel 42L, 42M, 42R.
Next, the pattern attached to each reel 42L, 42M, 42R will be described.
As shown in the figure, the pattern arrangement drawn on the reel tape wound around each of the left reel 42L, the middle reel 42M, and the right reel 42R is shown. As shown in the drawing, each of the reels 42L, 42M, and 42R is provided with 21 patterns in a row. Although numbers 1 to 21 are assigned to the respective reels 42L, 42M, and 42R, these are given for convenience of explanation, and are not actually attached to the reels 42L, 42M, and 42R. . However, in the following description, the number is used for explanation.

  As for the design, the “7” design (for example, the left reel tape 20th) and the “youth” design (for example, the left reel tape 19th) as the first special design for shifting to the big bonus game (BB game). There is. In addition, there is a “BAR” pattern (for example, the 14th reel tape on the left) as the second special pattern for shifting to the regular bonus game (RB game). In addition, there is a “replay” pattern (for example, the 11th reel reel tape) as a third special pattern for shifting to a replay (replay) game. Also, a “watermelon” design (for example, the 9th left reel tape), a “bell” design (for example, the 8th left reel tape), a “cherry” design (for example, the 9th) , Left reel tape 4th). In the reel tapes wound around the reels 42L, 42M, and 42R, the number and arrangement order of various patterns are completely different.

<Explanation of the number of payouts>
The number of payouts for each picture when winning is described.
Regarding the small role design, when the “Watermelon” design is aligned with the left, middle, and right on the active line, 15 medals are paid out. When the “Bell” design is aligned with the left, middle, and right on the effective line Pays out 8 medals, and when the “cherry” pattern on the left reel 42L stops on the active line, 2 medals are paid out. That is, the “cherry” pattern on the middle reel 42M and the right reel 42R is irrelevant to the medal payout. In addition, for the “cherry” design, medals are paid out regardless of the combination with the other design, so that the multiple effective lines of the left reel 42L overlap (specifically, the upper or lower level) with “ When the “cherry” pattern is stopped, medals are paid out by multiplying the number of overlapping active lines. As a result, in this embodiment, four medals are paid out.

  As for other designs, if the “7” design or “youth” design, which is a combination of the first special design (big bonus design), is aligned with the left, middle and right on the active line with the same design 15 medals are also paid out when the “BAR” pattern, which is a combination of 15 medal payouts and the second special pattern (regular bonus pattern), is aligned with the left, middle and right on the active line. In the present embodiment, for example, a case where a “7” pattern and a “cherry” pattern are simultaneously established may occur. In such a case, 15 medals are paid out. This is because the upper limit number for one medal payout is set to 15.

  Further, when the “replay” pattern that is the combination of the third special pattern is aligned with the left, middle, and right on the active line, the medal payout is not performed. In other cases, that is, when the “cherry” pattern of the left reel 42L does not stop on the active line and the same pattern as the left, middle, and right is not aligned on the active line, no medal payout is performed. When the “replay” pattern is aligned with the left, middle, and right on the active line, that is, when replaying is won, the next game can be started without betting medals. Here, simply inserting a medal from the insertion slot 75 (see FIG. 2) is “insertion”, and in order to start the game (the operation of the start lever 71 is valid), a necessary number of medals are inserted. A virtual medal (hereinafter also referred to as a credit medal as appropriate) stored and stored by a credit function (a function based on a credit mode described later) is used for the first to third credit insertion switches 77 to 79 (FIG. 2). The operation of (see) is applied (pressed down) to be applied and is distinguished as “bet”.

Although these display parts 35-37 are comprised by the 7 segment display, it is naturally possible to substitute by a liquid crystal display etc. FIG.

<Description of the game method (procedure for betting medals)>
Here, a procedure for betting medals will be described.
In both the direct mode and the credit mode, a bet is placed when a medal is inserted from the medal slot 75 at the start of the game. When the first medal is inserted from the medal slot 75 and a bet is placed, the first active line display section 32 is turned on, and the corresponding center line becomes the active line, and the second medal is the medal slot. When a bet is made from 75 and a bet is placed, the second active line display section 33 is further lit, and a total of three combination lines including the upper line and the lower line corresponding thereto become active lines, respectively, and the third medal Is inserted from the medal insertion slot 75 and betted, the third effective line display section 34 is further lit, and all five combination lines including a pair of diagonal lines corresponding thereto become effective lines. Hereinafter, the medals in the bet state are referred to as bet medals as appropriate.

  Further, when four or more medals are inserted from the medal insertion slot 75, the medals exceeding the three medals are regarded as surplus medals, and if the mode at that time is “direct mode”, the selector 83 causes the discharge passage 82 to be used. Is returned to the medal tray 18 from the medal discharge port 17. On the other hand, in the “credit mode”, surplus medals are stored inside the slot machine and stored as credit medals. Specifically, the number of surplus medals inserted is displayed as a credit number on the credit number display unit 35.

Thereafter, when a game is performed in the direct mode, if a medal is inserted from the medal slot 75, the medal is bet until the bet medal reaches three, and after the bet medal reaches three Will be returned as a surplus medal. When a game is performed in the credit mode, if a medal is inserted from the medal slot 75, the medal is bet until the bet medal reaches three, and the surplus after the bet medal reaches three. The medal is stored and stored as a credit medal. Specifically, a value obtained by adding the number of surplus medals to the number of credits already stored is displayed on the credit number display unit 35 as a new credit number.
Note that an upper limit number of credits (hereinafter referred to as the maximum number M as appropriate) is determined (for example, 50), and when a surplus medal exceeding that number is inserted, the selector 83 causes the medal outlet 17 to Returned to medal tray 18.

  Further, as described above, by operating the first to third credit bet switches 77 to 79, the credit medals (virtual medals) stored and stored can be bet to increase the bet medals. Specifically, when a game is played in the credit mode and the number of credit medals (virtual medals) stored and stored in the credit number display unit 35 is displayed as 1 or more, A virtual medal can be bet by pressing any one of the first to third credit bet switches 77 to 79.

  When the third credit bet switch 79 is pressed, the numerical value displayed on the credit number display unit 35 is decremented by one (decrease) as one virtual medal is inserted, and the first effective line display is displayed. The part 32 lights up and the center line becomes an effective line. When the second credit bet switch 78 is pushed, two numerical values displayed on the credit number display unit 35 are decremented as two virtual medals bet, and the first valid line display unit 32 and The second effective line display section 33 is lit and a total of three combination lines become effective lines. When the first credit bet switch 77 is pressed, three numerical values displayed on the credit number display unit 35 are decremented as three virtual medals bet, and all the effective line display units 32 to 32 are decremented. 34 lights up and a total of five combination lines become effective lines.

  When any of the first to third credit bet switches 77 to 79 is pressed, the number of virtual medals stored and stored is smaller than the predetermined number of virtual medals to be bet. For example, when the first credit bet switch 77 is pressed when the display of the credit number display unit 35 is “2”, all the values of the credit number display unit 35 are decremented to “0” and stored. Bets are placed for the stored virtual medals.

  As described above, in the slot machine dedicated to three bets, the second credit bet switch 78 and the third credit bet switch 79 are not provided on the exterior, but the internal structure can be adapted to each switch. Therefore, a switch can be provided by replacing the operation panel or partially modifying it as necessary.

<Overall configuration of manual circuit board fraud prevention mechanism>
FIG. 7 is a perspective view showing a manual substrate fraud prevention mechanism for manually moving the substrate box 300 according to the first embodiment. FIG. 8 is a front view showing a manual substrate fraud prevention mechanism for manually moving the substrate box 300 according to the first embodiment. FIG. 9 is a rear view showing a manual substrate fraud prevention mechanism for manually moving the substrate box 300 according to the first embodiment.
The manual fraud prevention mechanism according to the first embodiment includes a substrate box movable base 301 that supports the substrate box 300 movably through a support plate member, and the substrate box 300 is moved back and forth, up and down, The movable sliders 307, 308, and 309 are moved leftward and rightward and fixed (stopped).

  The substrate box movable base 301 includes two support receiving side plates 302 and a support receiving back plate 303 that connects the support receiving side plates 302 with a predetermined interval therebetween. The support receiving side plate 302 is a member in which a vertical plate 302a and a bottom plate 302b are connected and formed, and the bottom plate 302b is provided with a front and rear slide outer rail 305 that slidably engages an L-shaped plate material 304.

  The two support receiving side plates 302 are connected to each other by a support receiving back plate 303 with the bottom plates 302b facing inward and the vertical plates 302a opened at a predetermined interval. The horizontal width of the substrate box movable base 301 is set to be longer than the interval in the longitudinal direction of the substrate box 300. This is because a space for moving the substrate box 300 is necessary. In the illustrated example, the interval is slightly narrower than the lateral width of the housing 11. The substrate box movable base 301 is fixed to the inner wall of the housing 11.

  A support plate material is movably attached to the substrate box movable base 301. As shown in the figure, this support plate material is a plate material composed of an L-shaped plate material 304 in which a support vertical plate 304 a and a support bottom plate 304 b are connected at right angles, and a support horizontal plate 306 that connects the L-shaped plate material 304. .
