PROBLEM TO BE SOLVED: To securely return a movable member to the original position until the information (definition) of a final stopped symbol (at least until the following start of a symbol change pattern presentation), even if the movable member is operated when an abbreviated operation is carried out and the final stopped symbol indicating a lottery result is informed immediately thereafter. SOLUTION: An operation section 62 is operated to stop symbol change in a time t<SB>HK</SB>(1.0 second) according to a standard specification. Operation of the operation section 62 triggers return operation of a movable section 62 to the original position. Since the sum of the time t<SB>HS</SB>and a blanking period t<SB>BK</SB>is 1.6 seconds, the movable section 62 has enough time to return to the original position by the start-up of the following changing period, even if any load is applied to the returning movable section 62. The blanking period t<SB>BK</SB>provided between fall of the changing period and the start-up of the following changing period has time to spare which is twice as long as a time t<SB>MS</SB>required for the returning operation of the movable section 62.
