  In the symbol arrangement table, when the reel index is detected, the symbol positions existing in the middle stages of the display windows 21L, 21C, and 21R are set to “0”, and the symbols are arranged in the order of advance in the rotation direction of the reels 3L, 3C, and 3R. “0” to “20” are respectively assigned to the positions. Therefore, by managing how many symbols have been rotated since the reel index was detected, by referring to the symbol arrangement table, the positions of symbols existing mainly in the middle stages of the display windows 21L, 21C, and 21R and It is possible to always manage the type of the symbol.

[Program flow executed in pachislot]
Next, the contents of the program executed by the main CPU 31 of the main control circuit 71 will be described with reference to FIG.

[Main flowchart by control of main CPU of main control circuit]
FIG. 9 is a main flowchart showing basic control of the main CPU 31. When power is turned on to the pachi-slot 1, first, the main CPU 31 performs an initialization process (S1). Next, the main CPU 31 clears the designated storage area in the main RAM 33 (S2). In this process, for example, data stored in a storage area that needs to be erased for each game, such as an internal winning combination storage area or a display combination storage area, is cleared.

  Next, the main CPU 31 performs medal acceptance / start check processing (S3). In this processing, input checks of the medal sensor 42S and the start switch 6S are performed.

  Next, the main CPU 31 extracts a random value and stores it in a random value storage area provided in the main RAM 33 (S4). Next, the main CPU 31 performs an internal lottery process (S5). In this process, the internal winning combination is determined by lottery based on a random value. Next, the main CPU 31 transmits a start command to the sub-control circuit 72 (S6). The start command includes a parameter for specifying an internal winning combination.

  Next, the main CPU 31 requests the start of rotation of all the reels 3L, 3C, 3R (S7). When the start of rotation of all the reels 3L, 3C, 3R is requested, the driving of the stepping motors 49L, 49C, 49R is controlled by an interrupt process executed at a constant cycle (1.1173 msec), and each reel 3L , 3C, 3R starts to rotate.

  Next, the main CPU 31 performs a reel stop control process (S8). In this process, the input of the stop switch 7S is checked, and the rotation of the reels 3L, 3C, 3R is stopped based on the timing when the stop buttons 7L, 7C, 7R are pressed and the internal winning combination.

  Next, the main CPU 31 searches for a combination of symbols displayed along the winning determination line, and determines a payout number or the like based on the result (S9). As a result of the search, if the symbol combination displayed along the winning determination line matches the symbol combination defined by the symbol combination table, the corresponding display combination and the number of payouts are determined. Next, the main CPU 31 transmits a display command to the sub control circuit 72 (S10). The display command includes parameters that specify the display combination, the number of payouts, and the like.

  Next, the main CPU 31 performs a medal payout process (S11). In this process, the hopper 40 is driven and the number of credits is updated based on the determined payout number. Next, the main CPU 31 updates the bonus end number counter based on the payout number (S12). In this process, the numerical value determined as the payout number is subtracted from the bonus end number counter.

  Next, the main CPU 31 determines whether or not the bonus operating flag is on (S13). When determining that the bonus operating flag is on, the main CPU 31 performs a bonus end check process (S14). In this process, it is checked whether or not to end the operation of the bonus with reference to various counters for managing the end timing of the bonus.

  The main CPU 31 performs a bonus operation check process after S14 or when it is determined in S13 that the bonus operating flag is not on (S15). In this process, it is checked whether or not the bonus operation is started. When this process ends, the process proceeds to S2.

(Operation of open / close detection switch, etc.)
With reference to FIG.4 and FIG.5, the effect | action and effect of the opening / closing detection switch 60 which concern on the pachislot 1 are demonstrated.

  As shown in FIG. 4, when the front door 2 is closed, the permanent magnet 61 and the Hall IC 62 are close to each other. Therefore, the Hall IC 62 detects a strong magnetic field from the permanent magnet 61 and outputs an ON signal.

  On the other hand, as shown in FIG. 5, when the front door 2 is opened by a predetermined amount, the permanent magnet 61 and the Hall IC 62 are separated from each other, the magnetic field of the permanent magnet 61 does not reach the Hall IC 62, or the magnetic field is weakened. Outputs an off signal. In this way, the opening / closing detection switch 60 detects opening / closing of the front door 2.

  Further, since the permanent magnet 61 and the Hall IC 62 are provided so as not to protrude from the facing surfaces 63 and 64, the appearance of the front door 2 and the cabinet can be improved when the front door 2 is opened. There is no loss. Further, the maintenance person of the pachislot machine 1 does not inadvertently hook clothes or the like on the protruding portion, and does not interfere with the work.

  Further, since the open / close detection switch 60 does not protrude from the opposing surfaces 63 and 64, dirt such as dust or liquid is difficult to adhere, and the open / close detection switch 60 (particularly, the Hall IC 62) is unlikely to fail.

  As described above, according to the present embodiment, the open / close detection switch 60 is provided without protruding at a predetermined installation location, is smart in appearance, does not interfere with work, and can reduce the cause of failure. A pachislot 1 can be provided.

  Further, since the pachi-slot 1 is provided with the open / close detection switch 60 on the free end side of the front door 2, when the front door 2 is opened even a little, the relative distance between the permanent magnet 61 and the Hall IC 62 increases rapidly. A large magnetic field change can be detected. Therefore, the pachi-slot 1 can reliably detect even a slight opening of the front door 2.

  In the above embodiment, as shown in FIG. 5, the Hall IC 62 is provided in the recess 63a of the cabinet 1a and the permanent magnet 61 is provided in the recess 64a of the front door 2. However, the present invention is not limited to this. For example, as shown in FIG. 10, the permanent magnet 61 may be provided in the recess 63a of the cabinet 1a, and the Hall IC 62 may be provided in the recess 64a of the front door 2. In this case, the same effect as above can be expected.
