PROBLEM TO BE SOLVED: To provide a game machine capable of coping with a case in that an occurring abnormal state cannot be detected.SOLUTION: In a shift to a storage state, it is determined whether zero point position detection by a photosensor exists or not when zero point detection by a detection part does not exist (S5101-S5103). When the zero point position detection does not exist, it is determined whether a variable RT obtained by adding 1 is larger than a threshold SH1 (S5103-S5105). When the variable RT is equal to or less than the threshold SH1 (No for S5105), a connection part is moved by a predetermined angle in a direction so as to be in a proximity state (S5106). When the zero point position detection exists (Yes for S5103), the variable RT is initialized (S5107). When the zero point position detection does not exist (No for S5103), a retry is repeated until the variable RT becomes larger than the threshold ST1 or until the zero point position detection exists. When the zero point position detection still does not exist (Yes for S5105), error processing is performed (S5108).SELECTED DRAWING: Figure 51 |
