The reel position detection circuit 49 is a circuit that receives a pulse signal from the reel rotation sensor and supplies a signal for detecting the position of each reel 3L, 3C, 3R to the CPU 31. The payout completion signal circuit 47 generates a signal indicating completion of medal payout when the number of medals paid out from the medal hopper 21 reaches the designated number data.

  After the rotation of the reels 3L, 3C, 3R is started, the number of drive pulses supplied to each of the stepping motors 49L, 49C, 49R is counted, and the counted value is written in a predetermined area of the RAM 33a. From the reels 3L, 3C, 3R, reset pulses are obtained every rotation, and these pulses are input to the CPU 31 via the reel position detection circuit 49. The count value of the drive pulse counted in the RAM 32 is cleared to “0” by the reset pulse thus obtained. As a result, the RAM 32 stores a count value corresponding to the rotational position within one rotation range for each of the reels 3L, 3C, 3R.

  A symbol table (not shown) is stored in the ROM 33 in order to associate the rotational positions of the reels 3L, 3C, 3R as described above with the symbols drawn on the outer peripheral surface of the reel. In this symbol table, a code number that is sequentially given for each fixed rotation pitch of each reel 3L, 3C, 3R with reference to the rotation position where the reset pulse is generated, and a corresponding code number are provided. Is associated with a symbol code indicating the displayed symbol.

  When the CPU 31 determines the internal winning combination or the stop winning combination by lottery processing (probability random determination processing or the like) based on the random number sampling, the stop switch 18LS, Based on the operation signal sent from 18CS and 18RS and the determined stop table, a signal for controlling the stop of the reels 3L, 3C and 3R is sent to the motor drive circuit 50. However, when receiving an input of a command by the player, the CPU 31 sends a signal for controlling the reels 3L, 3C, 3R to stop the motor drive circuit 50 even if the player operates the stop buttons 18L, 18C, 18R. Do not send.

  Further, when the CPU 31 is in a stop mode (that is, a winning mode) indicating winning of the winning combination, the CPU 31 supplies a payout command signal to the hopper driving circuit 46 and pays out a predetermined number of medals from the medal hopper 21. The payout completion signal circuit 47 generates a signal for detecting a medal payout completion signal when the count value of the medal detection unit 21S (the number of medals paid out from the medal hopper 21) reaches the designated number data. To do.

  That is, the medal detection unit 21S counts the number of medals to be paid out from the medal hopper 21 and outputs a medal payout completion signal to the CPU 31 via the payout completion signal circuit 47 when the counted value reaches a designated number. Is input. As a result, the CPU 31 stops driving the medal hopper 21 via the hopper driving circuit 46 and ends the medal payout process.
