PROBLEM TO BE SOLVED: To provide a game machine equipped with a variable display which can prevent a rotary belt from rotating in vain caused by the frictional force of a pressure roller, by rotating and driving the pressure roller in the delivery direction of the rotary belt accompanying the rotary drive of the driving roller. SOLUTION: This rotary belt mechanism comprises a driving roller 91 arranged so that the periphery of the rotary belt should be in touch with a film belt 55, a stepping motor 90 for rotating and driving the driving roller 91, a pressure roller 50 for pressing a film belt 55 against the driving roller 91, and a stepping motor 80 for rotating and driving the pressure roller 50 in the delivery direction of the film belt 55 accompanying the rotary drive of the driving roller 91. This mechanism can prevent the film belt 55 from rotating in vain caused by the frictional force of the pressure roller 50, so that the mechanism enables the film belt 55 to rotate smoothly. |
