PROBLEM TO BE SOLVED: To solve the problem that a light guide plate exclusive for illuminating a lower tray has to be fixed to the inner side of a panel holding frame with the use of a bolt, etc., concerning a conventional slot machine using part of illumination light for a lower panel as token receiver illumination. SOLUTION: The conventional problem is solved by: allowing a display seal, where management information such as a certificate stamp or game-related information such as a dividend table are printed, to adhere to a display plate made of a transparent material; fixedly attaching the display plate to the panel-holding frame of the lower panel with one operation; and using the display plate also as the light guide plate for illuminating the lower tray, thereby improving an additional value.
