  FIG. 1 shows a configuration of an example of a drawing toy for explaining an embodiment of the present invention, and FIG. 2 shows a cross section of the drawing toy of FIG.

  A drawing toy 1 shown in FIG. 1 includes a placement unit 2 on which a sheet such as an original sheet on which a main picture is drawn or a copy sheet that copies the main picture drawn on the original sheet is placed; The light emitting unit 3 that generates illumination light that illuminates the sheet placed on the light source, the reflective sheet 4, and the housing 5 that houses the placement unit 2, the light emitting unit 3, and the reflective sheet 4.

  The mounting portion 2 is made of a substantially rectangular plate material made of a transparent resin such as acrylic, and is formed of a single member. One surface 2 a of the placement portion 2 is a placement surface on which the sheet can be placed, and the placement surface 2 a is exposed through a window portion 6 formed in the housing 5.

  The light emitting unit 3 includes a plurality of LEDs 7 as light sources, a control IC (not shown) that controls lighting of the LEDs 7, a power source (not shown) that supplies power to the LEDs 7 and the control IC, and an operation switch 8. .

  The plurality of LEDs 7 include an LED 7w that emits white light (first color), an LED 7r that emits red light (second color), and an LED 7b that emits blue light (third color).

  The control IC has a first mode in which the white LED 7w is continuously lit and a second mode in which the red LED 7r and the blue LED 7b are alternately lit. The operation mode of the control IC is sequentially switched in the order of turning off → first mode → second mode → turning off →.

  In the illustrated example, the plurality of LEDs 7 are arranged along the side edge 2c on one side of the placement portion 2. The light emitted from each of the LEDs 7 is incident on the mounting portion 2 through the side edge 2c. Preferably, each of the LEDs 7 is disposed in close contact with the side edge 2c as shown in FIG. By arranging the LED 7 in close contact with the side edge 2 c, it is possible to suppress each outgoing light of the LED 7 from being reflected between the side edge 2 c and the LED 7, and to make the outgoing light efficiently enter the mounting portion 2. be able to. Thereby, the efficiency in which each emitted light of the LED 7 is used as illumination light for illuminating the sheet placed on the placement unit 2 can be increased.

  In the illustrated example, the LED 7 is disposed on the side edge 2c on one side of the placement unit 2, but can be disposed on the side edge 2d on the opposite side, for example, and is disposed on the side edges of the four sides. You can also.

  The surface 2b of the mounting part 2 opposite to the mounting surface 2a is a light guide surface capable of guiding light incident on the mounting part 2 from each of the LEDs 7 to the mounting surface 2a. The light guide surface 2b is a rough surface, scatters the light incident on the mounting portion 2, and diffuses the incident light over substantially the entire surface of the mounting surface 2a.

  The light guide surface 2b is supported by the bottom 9 of the housing 5 that faces the light guide surface 2b. For example, when an original sheet and a copy sheet are placed on the placement surface 2a and a main picture drawn on the original sheet is copied onto the copy sheet, a load acts on the placement portion 2, but the light guide surface 2b By being supported by the bottom portion 9 of the housing 5, it is possible to suppress the bending of the placement portion 2.

  Preferably, the light guide surface 2b supported by the bottom portion 9 of the housing 5 has a large number of minute convex portions 10 provided in a distributed manner in the surface as shown in FIG. A large number of convex portions 10 form an air layer between the light guide surface 2b and the bottom portion 9 of the housing 5, and reflection caused by a difference in refractive index between the light guide surface 2b and the bottom portion 9 of the housing 5. By positively generating the light, it is possible to efficiently guide the light incident on the placement portion 2 to the placement surface 2a. Thereby, the efficiency in which each emitted light of the LED 7 is used as illumination light for illuminating the sheet placed on the placement unit 2 can be increased. Further, the light guide surface 2b can be roughened by the large number of convex portions 10.

  The reflection sheet 4 is provided adjacent to the light guide surface 2b of the placement unit 2, and reflects light emitted from the placement unit 2 toward the bottom 9 of the housing 5 without being reflected by the light guide surface 2b. The light is reflected again toward the placement unit 2. Thereby, the efficiency in which each emitted light of the LED 7 is used as illumination light for illuminating the sheet placed on the placement unit 2 can be increased. As the reflection sheet 4, for example, a milky white paper material can be used.

  As shown in FIG. 2, the reflection sheet 4 is held between the light guide surface 2 b and the bottom portion 9 of the housing 5. Thus, in the present example in which the light guide surface 2b of the placement unit 2 is supported by the bottom 9 of the housing 5, the holding of the reflection sheet 4 can be simplified and the cost of the drawing toy 1 can be reduced. .

  FIG. 3 is a diagram illustrating a usage example of the drawing toy 1.

  In FIG. 3, the original sheet 11 and the copy sheet 12 are placed in this order on the placement surface 2 a of the placement unit 2, and the copy sheet 12 in which the main picture Pic drawn on the original sheet 11 is superimposed on the original sheet 11. An example of use when copying is shown below. In this usage example, the light emitting unit 3 is operated in the first mode, and the white LED 7w is continuously lit.

  The light incident on the mounting portion 2 from the white LED 7w is mainly scattered by the light guide surface 2b of the mounting portion 2 and diffused over substantially the entire surface of the mounting surface 2a, and the original placed on the mounting surface 2a. The sheet 11 and the copy sheet 12 are illuminated over the entire area of the placement surface 2a. Thereby, the main picture Pic drawn on the original sheet 11 through the copy sheet 12 is visually recognized, and the main picture Pic can be copied to the copy sheet 12.

  In this embodiment, since the mounting part 2 is comprised by one member, there is no reflection resulting from the refractive index difference between the members in the case of comprising a plurality of members, and each emitted light of the white LED 7 Increases the efficiency used as illumination light for illuminating the sheet placed on the placement unit 2. Thereby, the visibility of the main picture Pic of the original sheet 11 viewed through the copy sheet 12 can be enhanced. In addition, as in the above-mentioned Patent Document 1, the cost increases when the light guide that guides the light emitted from the light emitting diode to the sheet placed on the transparent plate is constituted by a plurality of members. In this case, by configuring the mounting portion 2 with a single member, the cost of the drawing toy 1 can be reduced as compared with the case where the mounting portion 2 is configured with a plurality of members.

  FIG. 4 is a diagram showing another example of use of the drawing toy 1.

  In FIG. 4, the first sheet 13 and the second sheet 14 on which different pictures are depicted, and the covering sheet 15 that covers the first sheet 13 and the second sheet 14 in a transparent manner are placed on the placement surface 2 a of the placement unit 2. An example of use in which a pseudo moving image is displayed by a picture placed and drawn on each of the first sheet 13 and the second sheet 14 will be described. In this usage example, the light emitting unit 3 is operated in the second mode, and the red LED 7r and the blue LED 7b are alternately lit.

  On the first sheet 13, a picture Pic1 is drawn in a red color corresponding to the color of the emitted light of the red LED 7r, and on the second sheet 14 a blue color corresponding to the color of the emitted light of the blue LED 7b. The picture Pic2 is drawn in the color of.

  The covering sheet 15 that covers the first sheet 13 and the second sheet 14 in a transparent manner is a transparent member having the same color as either the color of the emitted light from the red LED 7r (red) or the color of the emitted light from the blue LED 7b (blue). In this example, the color of the light emitted from the red LED 7r is red.

  The first sheet 13 and the second sheet 14 are stacked with the first sheet 13 on which a picture is drawn in the same color as the covering sheet 15 facing up, and then placed in a state of being covered by the covering sheet 15. 2 is placed on the placement surface 2a.

  FIG. 5 shows an example of a display mode of pictures drawn on the first sheet 13 and the second sheet 14 in the usage example of FIG. 4, and FIG. 5 (A) shows a state in which the red LED 7r is turned on. 5 (B) shows the state in which the blue LED 7b is lit.

  As shown in FIG. 5A, when the red LED 7r is turned on and the first sheet 13 and the second sheet 14 are illuminated by red illumination light, the second sheet 14 drawn in blue The visibility of the picture Pic2 is increased. On the other hand, the picture Pic1 of the first sheet 13 drawn in red similar to the red illumination light is illuminated with the red illumination light, so that the difference in color tone from the other areas in the first sheet 13 is small. Since it is covered with the red covering sheet 15, the visibility is lowered.

  As shown in FIG. 5B, when the blue LED 7b is turned on and the first sheet 13 and the second sheet 14 are illuminated with blue illumination light, the first sheet 13 drawn in red The visibility of the picture Pic1 is increased. On the other hand, the picture Pic2 of the second sheet 14 drawn in blue similar to the blue illumination light is illuminated with the blue illumination light, so that the difference in color tone from other areas in the second sheet 14 is small. And is covered with the first sheet 13, the visibility is lowered.

  Therefore, when the red LED 7r and the blue LED 7b are alternately turned on, the picture Pic1 drawn on the first sheet 13 and the picture Pic2 drawn on the second sheet 14 are alternately visually recognized. Thereby, a pseudo moving image can be displayed by the picture Pic1 drawn on the first sheet 13 and the picture Pic2 drawn on the second sheet 14.
