[Main flowchart by control of main CPU of main control circuit]
FIG. 11 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 slide cover, etc.)
Next, the action and effect of the slide cover 45 according to the pachislo 1 will be described with reference to FIGS.

  During normal times when the switch unit 44 of the power supply device 43 is not operated, the slide cover 45 is closed, and the front plate portion 45a of the slide cover 45, the side plate portions 45b and 45b, and the top plate portion 45c of the front surface portion 43a of the power supply device 43. Is covered from all sides. Thereby, the illegal act to the switch part 44 of the power supply device 43 can be prevented reliably.

  The slide cover 45 opens and closes in the vertical direction and does not open and close in the left-right direction (the direction that closes the front of the hopper 40). Therefore, the hopper 40 is pulled out toward you with the slide cover 45 forgotten to close. However, the hopper 40 does not come into contact with the slide cover 45, and the slide cover 45 can be easily prevented from being damaged.

  In addition, since the slide cover 45 can be locked at an arbitrary position with respect to the power supply device 43 by providing the leaf spring 46, the clerk can easily operate the switch unit 44 without gripping the slide cover 45. Can do.

  Further, since the slide cover 45 is formed of a transparent resin, the switch unit 44 of the power supply device 43 can be easily confirmed even when the slide cover 45 is closed, so that a desired switch operation can be performed immediately after the slide cover 45 is opened. The workability is good.

  As described above, the pachi-slot 1 according to the present embodiment can improve the workability of a staff member and can reliably prevent an illegal act on the switch unit 44 of the power supply device 43.

  In the above embodiment, the slide cover 45 is configured to be slidable in the vertical direction by the groove 43c of the power supply device 43 and the protruding piece 45d of the slide cover 45. However, the present invention is not limited to this. Any configuration is possible as long as the slide cover 45 can be slid in the vertical direction.

  Moreover, in the said embodiment, although demonstrated as providing three leaf | plate springs 46 in the side parts 43b and 43b of the power supply device 43, respectively, it is not limited to this, The side plate part 45b of the slide cover 45 is made into predetermined elastic force. The number of leaf springs 46 may be two or less, or four or more.
