PROBLEM TO BE SOLVED: To more smoothly rotate a reel without increasing the number of steps of a stepping motor when a symbol display is rotated with the stepping motor. SOLUTION: A stepping motor case 15 is partitioned with a wall 40 and a motor 42 and a stator 43 are placed thereunder. A small diameter drive gear 45 is fixed on a drive shaft 41 integrally rotated with the rotor 42. The drive gear 45 is made mesh with the large diameter gear 46 of a transmission gear 48, and an output gear 49 fixed on an output shaft 18 in engaged to a small diameter gear 48 integrally rotated with the large diameter gear 46. Rotation of the drive shaft 41 is reduced with two pairs of reduction gear mechanisms and transmitted to the output shaft 18. |
