A power switch 6 for energizing the light emitting display device 1 is disposed on the front surface of the base 2. The light emitting display device 1 emits light by the power supplied from the power source via the power cord 5, but may emit light by the power stored in the battery, the power generated by the solar cell, or the like.

  The Thomson blade 7 used when processing the display content A is formed in a size and a shape corresponding to the contour line of the display content A having a butterfly pattern, and processes the linear groove 3b having a desired depth. It is formed of a metal plate having a hardness suitable for (see FIG. 4). Further, the Thomson blade 7 is formed to have a thickness suitable for processing the linear groove 3 b with respect to the display surface 3 a of the light guide plate 3. The cutting edge of the Thomson blade 7 is formed in a cutting edge angle and a cutting edge shape suitable for processing the linear groove 3b.

  Next, the 1st processing method which processes the display content A of a butterfly pattern with respect to the display surface 3a of the light-guide plate 3 is demonstrated.

  First, as shown in FIG. 4, a light guide plate 3 in which a single Thomson blade 7 formed in a size and shape corresponding to the display content A of a butterfly pattern is placed on the upper surface of the placement table 9 of the processing device 8. It is attached to the lower surface of the movable table 10 disposed above the mounting table 9 so as to face the display surface 3a. Further, the light guide plate 3 having translucency is placed horizontally on the upper surface of the placing table 9 disposed below the movable table 10.

  Thereafter, the movable table 10 is vertically lowered downward by a lifting device (not shown), and the Thomson blade 7 attached to the movable table 10 is placed on the display surface 3 a of the light guide plate 3 mounted on the mounting table 9. While pressing vertically from above, the edge of the light guide plate 3 bites into the display surface 3a at a substantially right angle (for example, 90 degrees).

  The Thomson blade 7 is made to bite into the display surface 3a substantially uniformly along the contour line of the display content A drawn on the display surface 3a of the light guide plate 3 by a desired depth. After processing the display content A composed of the linear grooves 3b formed when the Thomson blade 7 is bitten into the display surface 3a of the light guide plate 3, the movable base 10 is vertically raised upward, and the Thomson blade 7 Is extracted from the display surface 3 a of the light guide plate 3. In addition, the groove part 3b is formed in the depth by which the light of each LED element 4 ... injected into the inside of the light-guide plate 3 is diffused.

  If the light guide plate 3 processed with the display content A is separated from the mounting table 9 after the movable table 10 is lifted and stopped to a predetermined height, the butterfly-shaped display content A composed of the linear grooves 3b is displayed on the light guide plate 3. The work for processing the display surface 3a is completed.

  That is, since the single Thomson blade 7 formed in a size and shape corresponding to the entire display content A of the butterfly pattern is bitten into the display surface 3a of the light guide plate 3, the display content A composed of the linear groove portions 3b. Can be processed with respect to the display surface 3a of the light guide plate 3 by one processing operation.

You may change it. Further, the display content A may be formed on the entire display surface 3 a of the light guide plate 3 or a part thereof.

  Next, when the display content A drawn on the light guide plate 3 of the light emitting display device 1 is caused to emit light, as shown in FIGS. 1 and 2, the light guide plate 3 on which the display content A is processed is placed on the upper surface side of the base 2. After being inserted and fixed in the opening 2a, the power switch 6 is turned on to turn on / flash the LED elements 4 built in the base 2, so that they are inserted into the upper surface side opening 2a of the base 2. Light projected from each LED element 4 is irradiated onto one end face of the light guide plate 3.

  Light incident on the inside of the light guide plate 3 from one side end face of the light guide plate 3 is diffused by the groove portion 3b of the display content A drawn on the display surface 3a of the light guide plate 3, and corresponds to the front surface of the light emitting display device 1. The light is emitted outward from the display surface 3a of the light guide plate 3 (see FIG. 3). Thereby, since the whole linear groove part 3b processed on the display surface 3a of the light-guide plate 3 light-emits, the display content A drawn by the linear groove part 3b can be light-emitted and displayed.

  As described above, the Thomson blade 7 formed in a size and shape along the contour line of the display content A is bitten into the display surface 3a of the light guide plate 3 having translucency. Since the display content A composed of the linear grooves 3b formed at the time is processed, it is not necessary to move the Thomson blade 7 to a desired processing position, and the processing operation of the desired display content A such as a butterfly pattern is simple and easy. Easy to do. Further, the work time required for processing the display content A can be shortened, and the efficiency of the processing work can be improved. Further, since no waste such as burrs, chips and cutting powder is generated during processing, the display content A can be processed cleanly. In addition, since the cost burden for waste disposal is unnecessary, the processing cost can be reduced.

  Moreover, you may change the biting angle of the Thomson blade 7 with respect to the display surface 3a of the light-guide plate 3 to the desired angle included in the range of 0 degree or more and 90 degrees or less, for example. That is, if the biting angle of the Thomson blade 7 is close to 90 degrees, the amount of light emitted toward the outside increases. Further, if the biting angle of the Thomson blade 7 is close to 0 degrees, the amount of diffusion of the light emitted toward the outside is reduced, so that light emission display can be performed due to the luminance difference.
