PURPOSE:To provide a simple construction requiring none of an auto-emitter, a power supply, a wiring work and a control apparatus by using reflected light of a prism sheet. CONSTITUTION:A plurality of base patterns 2 are arranged on a prism sheet 1. Pillars 3 of pink color condensed to a center part of the patterns 2 are erected and appears by light of an incandescent lamp 9. Thereby, optional characters and patterns can be obtained by bringing a sheet 4 in tight contact-on a sheet 1 and clipping a plurality of optional characters and patterns 5-1, 5-2 and 5-3 and putting them on the sheet 4. A timing bar 7 is turned by turning the winding axis 8 of the sheet 4 so that the sheet 4 can be moved and the next optional characters and patterns can appear. |
