<P>PROBLEM TO BE SOLVED: To provide an illuminating decorative sheet capable of emitting light as a design on the entire body thereof without allowing a game player to view a light source even when it is difficult to secure a light source since the illuminating decorative sheet is separated from a game board surface. <P>SOLUTION: The illuminating decorative sheet includes a luminous board 10 that is separately disposed forward of the game board surface in parallel with the game board surface and has luminous portions 10a and a shading portion 10b provided on the front surface thereof, a rib 11 that is standingly disposed on the rear surface thereof, and a printed board 20 that has a plurality of LEDs 21 which are disposed along the disposed shape on the luminous board and cause light to enter from one end surface of the opposing rib. The luminous board 10 has a plurality of recessed portions 50 each of which subsides from the front surface to the rear surface and gradually increases in depth and area with an increasing distance from a portion bonded to the rib in a planar direction. Light that is emitted from the LEDs 21 and enters the rib 11 is reflected in a planar direction of the luminous board 10 at an interface between the rib's end surface 11b and a groove 10d of the luminous board, and enters the luminous board 10 after refraction, and is emitted by each of the recessed portions 50 from the front surface of each of the luminous portions 10a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
