PURPOSE: To transmit various informations according to a situation by using a surface light source device. CONSTITUTION: A display device is composed of a light source part 1 and a light conductive display part 2, and the light source part 1 is constituted so as to have a lamp 6 or the like on a pinball stand, and a guide member 7 is arranged on the peripheral edge of its opening 3a. The light conductive display part 2 is constituted of a locking tool 11 and a light conductive panel 8, and the locking tool 11 can be inserted into and extracted from the guide member 7. The light conductive panel 8 is constituted by sticking a reflecting sheet 13 to one side surface or the like of a transparent acrylic plate 12 and a diffusing sheet 14 to its other surface side, and characters such as 'a great hit' are recorded on the diffusing sheet 14. Since the light conductive panel 8 on which plural kinds of different characters or the like are recorded can be replaced according to a situation, information can be flexibly transmitted. |
