FIG. 4 is an exploded perspective view of the drawing stand toy 100 according to the embodiment of the present invention. FIG. 5 is a perspective view showing the front and back surfaces of the plate body 20 of the drawing stand toy 100 according to the embodiment of the present invention.

  As shown in FIG. 4, the drawing stand toy 100 has a plate body 20, a reflecting plate 60, a light emitting diode 50 having a light confusing structure on the back side inside the frame 10 and the housing 90. Etc.

  The frame 10 is a plate made of lightweight hard resin and forms a frame around the trace base at the top, and the housing 90 is a lattice to form a base for housing built-in parts at the bottom. A large number of ribs are formed on the inner wall surface, and the drawing table toy 100 is formed so as to be sandwiched between the two ribs, and several illumination members are stored therein.

  The surface of the plate 20 is a portion that emits illumination light from the back as a paper storage place for the drawing stand toy 100 and further as a trace stand region. The plate 20 is a substantially rectangular plate made of an acrylic material or the like, which is a hard and sturdy transparent resin having a thickness of about 5 mm. As shown in FIG. 5A, the plate body 20 includes a smooth portion 40 whose surface is a transparent or semi-transparent trace base, and a frame locking portion 41 that engages the frame 10 on the periphery of the plate body 20. It is what you have.

And the peripheral edge of the plate 20 are held.

  Then, as shown in FIG. 5 (b), the plate body 20 is formed with ribs 25 on the peripheral edge so that the substantially entire back surface is recessed from the periphery, and an optical confusion structure is formed inside the peripheral edge of the back surface. A number of concavo-convex portions 30 that are formed by cutting grooves vertically are arranged on one surface in the longitudinal direction. Furthermore, as the surface treatment of the uneven portion 30, a satin finish treatment 21 is performed for the purpose of diffusing illumination light. The back surface of the plate body 20 has a plurality of light sources irradiated from the side surfaces of the concavo-convex portions 30 on both sides of the plate body 20 by forming the concavo-convex portions 30 that are parallel to the longitudinal direction of the rectangle on one surface. It has a function to diffusely reflect the light from.

  The uneven portion 30 is formed by cutting a groove having a width of about 1 mm and a depth of 1 mm every 5 mm at the periphery of the plate 20, and a depth of 1 mm and a width of about 2.5 mm every 5 mm in the center of the plate 20. The groove is cut and formed. As a result, the groove width is increased even in the vicinity of the center of the plate body 20 where the distance from the light source located at the peripheral edge of the frame 10 is long and it is difficult for light to reach, thereby reflecting light rays parallel to the surface of the plate body 20. The amount of light transmitted through the plate surface can be increased near the center of the plate to increase the amount of light.

  Further, the plate body 20 has a function of diffusing illumination light by making the uneven portion 30 on the entire back surface a matte treatment 21, and the uneven portion 30 on the back surface that can be seen through when the plate body 20 is seen from the front surface. Makes the longitudinal lines inconspicuous.

  Furthermore, since the substantially entire back surface is made to recede from the rib, and a slight space is formed between the reflector 60, the light irregularly reflected on the back surface in the direction of the reflector is reflected by the reflector 60, and again The light transmitted through the back surface can be uniformly dispersed by being scattered when transmitted through the back surface.

  Then, the plate body 20 can be manufactured easily and inexpensively by forming the concave and convex portion 30 on one surface, for example, by injection molding using a mold that has a simple shape and does not require relatively high accuracy. It is supposed to be.

  The light-emitting diode 50 is a light source of the drawing stand toy 100, and is composed of chip-type high-intensity white LEDs mounted on the substrate at equal intervals as shown in FIG. It is arrange | positioned inside each periphery which the longitudinal direction of the drawing stand toy 100 opposes inside. Further, the light emitting diode 50 is disposed so as to emit light from the end face of the plate body 20. By using the light emitting diode 50 that emits white light, the drawing stand toy 100 having a long light emission lifetime can be obtained.

  The reflector 60 is a flat mirror made of an aluminum sheet or the like formed by vapor-depositing aluminum on the surface of a glass material or metal material. Together with the plate 20, the light emitted from the light-emitting diode 50 is efficiently surface-emitted. It is to be converted.

  Further, as shown in FIG. 4, the drawing stand toy 100 has a battery storage chamber 80 for the battery, and the battery storage chamber 80 is a single battery serving as a main power source for turning on the light emitting diode 50, A plurality of predetermined general-purpose batteries such as AA batteries or AA batteries are accommodated. The battery storage chamber 80 is the only thick portion in the housing 90, and protrudes downward to form a leg 95 as shown in FIG. 7, and the drawing toy 100 itself is inclined. Yes.

  The drawing stand toy 100 uses a stored battery as a main power source, configures a constant current and a constant voltage by a predetermined circuit, and simultaneously arranges a plurality of light emitting diodes 50 based on the ON / OFF operation of the switch 15. Turn on and off.

  Next, an internal structure that enables surface light emission in the drawing stand toy 100 will be described with reference to the drawings.

FIG. 7 is a longitudinal sectional view of the drawing stand toy 100 according to the embodiment of the present invention.

  As shown in FIG. 6, the drawing stand toy 100 is easily manufactured with a configuration in which the light emitting diode 50 is arranged near the edge of the plate 20 and the inside of the casing is composed of the reflector 60 and the plate 20 with a small number of parts As a result, surface emission is possible.

  Specifically, the light emitted from the light emitting diodes 50 arranged on the inner sides in the longitudinal direction on both sides of the toy is incident from the side surfaces of the plate body 20, so that the light is incident on the inside of the plate body 20 and the reflector 60. When traveling through the space formed between them, the light that has reached the uneven surface or the uneven boundary surface of the uneven portion 30 is reflected by the uneven surface toward the upper trace table or the lower reflector 60. Is done.

  Then, by providing a space between the back surface of the plate body 20 and the reflection plate 60, the downward light reflected by the uneven portion 30 is reflected by the reflection plate 60, and until the matte treatment 21 on the surface of the uneven portion 30 This causes a light diffusion effect.

  In addition, the light that is incident from the side surface of the plate body 20 and travels in the interior of the plate body 20 or in the lower space becomes nearly parallel to the surface of the plate body 20 as the light travels from the side surface of the plate body 20 to the center, and from above the surface. Although the amount of light transmitted to the light is attenuated, the width of the groove of the concavo-convex portion 30 is increased to efficiently perform irregular reflection to increase the amount of light. Since the light is shielded from light at the peripheral edge of the frame 10, the trace area can be surface-emitting relatively uniformly.

  Further, in the longitudinal cross section of the drawing stand toy 100, as shown in FIGS. 4 and 7, the light emitting diodes 50 are arranged at equal intervals in the longitudinal direction inside the housing 90, respectively. .

  If the light emitting diodes 50 are arranged so as to be densely spaced at equal intervals in the longitudinal direction, the illumination light in the trace table area can be made more uniform, and lightness spots in the trace table area can be reduced.

  In addition, since the stoppers 18 and 19 and the paper holder 17 are provided on the periphery of the trace table so as to face each other, the paper is prevented from inadvertently moving when drawing a copy picture. be able to.

  Further, as shown in FIG. 7, the casing 90 has legs 95 below, and the trace table is slightly inclined, so that the trace table is easy for children to draw and draw pictures.

  As described above, according to the present embodiment, as a trace table for educational toys useful for children's drawing learning, it is possible to emit light while reducing the number of parts, and it is lightweight and convenient to carry. Can be provided.

  Furthermore, according to the present embodiment, the uneven portion 30 of the plate body 20 is formed such that the width of the convex portion is shortened and the width of the convex portion is increased at the periphery of the plate body 20, and the concave portion and the convex portion are formed at the center of the plate body 20. Since the widths of the portions are substantially equal, the surface of the plate 20 can be transmitted through the surface of the plate 20 even at a distance from the light source located at the peripheral edge in the longitudinal direction of the housing to increase the amount of light and make it brighter.
