PROBLEM TO BE SOLVED: To change the width and number of rotary members of a pachinko game machine having a variable display device with plural rotary members mounted side by side in a storage housing. SOLUTION: Engagement parts (engaging grooves 116a-121b) for positioning and supporting drum attaching base boards 55, 56 and 57 inside a drum housing 58 by the engagement with the drum attaching boards 55, 56 and 57 are mounted in the drum housing 58. By mounting the engagement parts at plural positions in the drum housing 58 at least for one drum attaching base board, the storage position of each drum attaching base board in the drum housing 58 can be changed in plural ways. Therefore, the recycling of the variable display device involving large-scale changes such as the change of the width of rotary drums (display width of patterns) and change of the number of rotary drums (number of patterns to be displayed in parallel), etc., is possible. |
