PROBLEM TO BE SOLVED: To accurately rotate a display belt in a rotation display device and to easily correct its positional deflection. SOLUTION: In this rotation display device for a game machine, the display belt 1 suspended between pulleys 2 and 3 for use is used as a timing belt so that a display range for a pattern 5 is spread over the full width of the belt. A single original point detection part 11 is arranged in the vicinity of the edge part of the inner circumference face of the display belt 1, and a detection switch 4 is arranged to face the passage locus of the original point detection part 11 for detecting the rotation position of the display belt. If the positional deflection is generated, the original point detection part 11 is deformed to change the detection position for carrying out correction operation. |
