The diffused light A1 is diffused and transmitted through the outer surface 422 (see FIG. 9), and the light A2 reflected from the double-sided reflector 401 is diffused and transmitted through the outer surface 422 (see FIG. 9). Diffusion processing for diffusing light is performed on the end surfaces 426 and 428 on the short side of one and the other of the acrylic diffusion plate 403. A semi-cylindrical shaft half 430 is formed on the other long side of the acrylic diffusion plate 403 (one side of the display plate 132a).

  On the outer surfaces 421 and 422 of the acrylic diffusion plates 402 and 403 on the one surface side and the other surface side, pattern layers 404 and 405 made of a translucent material are formed in the shape of the pattern by silk screen printing, for example. Yes.

Let Next, the display control board 96 causes the stepping motor 121 to perform test rotation and rotates the spur gear 123 and the rotating drum 131 to cause the rotation position detection sensor 103 to detect the rotation position detection index 210 of the spur gear 123, thereby rotating the rotation drum. The rotation reference position 131 is detected. Thereafter, the display control board 96 uses the rotation reference position as a reference, grasps the rotation position of the rotary drum 131 based on how many pulses are supplied to the stepping motor 121 from this position, and controls the rotation of the stepping motor 121. Do.

  Thereafter, the display control board 96 moves the stopper 141 to the locking position of the display plates 132a, 132b, 132c,. Next, the CPU 501 positions the intermediate portion of the support hole 194 where the stop position of the rotating drum 131 is adjacent to the center of the display window 113 in the vertical direction, that is, the display plates 132a, 132b, 132c,. Among them, the drive stop control of the stepping motor 121 is performed so that the pair of upper and lower display plates at the display position (in the case of FIG. At the same time, the display control board 96 supplies power to the plurality of light emitting diodes 333 provided in the light projecting units 301, 302, 303, and 304 to light them.

  When the rotary drum 131 is stopped, the upper display board (in the case of FIG. 5, the display board 132b) is locked by the stopper 141, and a pair of upper and lower display boards (in the case of FIG. 5). , The display boards 132b and 132a are vertically and planarly arranged, and a pair of upper and lower display boards (in the case of FIG. 5, the display boards 132b and 132a) is set as one set 211 (FIG. 4) from the front through the display window 113. And FIG. 5) are displayed. Further, in this state, a plurality of light emitting diodes provided in the light projecting units 303 and 304 are provided on the end surfaces 423 and 424 (see FIGS. 7 and 9) of the lower display panel (in the case of FIG. 5, the display panel 132a). Light A1 from 333 enters. Light A1 from the plurality of light emitting diodes 331 provided in the light projecting units 301 and 302 is applied to the end surfaces 423 and 424 (see FIGS. 7 and 9) of the upper display plate (in the case of FIG. 5, the display plate 132b).
