Summary of the Invention
Problems to be Solved by the Invention
[0005] However, the disclosed technology of Patent Document 1 assumes that the light-emitting diodes provided on the trading card emit light, and does not assume that the still images included in the trading card emit light. For this reason, there is a problem that the still images included in the trading card cannot be made to emit light in the disclosed technology of Patent Document 1.
[0006] Therefore, the present invention has been devised in view of the above-described problems, and an object thereof is to provide a light-emitting trading card capable of making a still image included in the trading card emit light.
Means for Solving the Problems
[0007] The light-emitting trading card according to the first invention comprises a lower layer including organic EL (electro-luminescence), a middle layer provided above the lower layer and including an image film printed with a still image, and an upper layer provided above the middle layer and including a translucent film that transmits visible light.
[0008] The light-emitting trading card according to the second invention is characterized in that, in the first invention, the upper layer includes a polarizing film that removes reflected light instead of the translucent film.
[0009] The light-emitting trading card according to the third invention is characterized in that, in the first and second inventions, the middle layer includes an image film printed with the still image consisting of a color having a wavelength different from the wavelength included in the light irradiated by the organic EL.
[0010] The power supply cartridge according to the fourth invention is characterized by supplying power to the light-emitting trading card in the first or second invention.
Advantages of the Invention
[0011] According to the first to third inventions, the light-emitting trading card includes a lower layer including organic EL (electro-luminescence) and a middle layer including an image film printed with a still image. Thereby, the light irradiated from the organic EL in the lower layer causes the still image in the middle layer to emit light. For this reason, it becomes possible to cause the still image included in the light-emitting trading card to emit light.
[0012] Further, particularly in the first invention, the light-emitting trading card includes an upper layer including a translucent film that transmits visible light. Thereby, it becomes possible to view the still image in the middle layer from the upper surface of the translucent film. For this reason, it becomes possible to confirm the still image in the middle layer without irradiating light.
[0013] In particular, according to the second invention, the upper layer includes a polarizing film that removes reflected light instead of the translucent film. As a result, it becomes impossible to view the still image of the middle layer from the upper surface of the translucent film. Therefore, until light is irradiated, the still image drawn on the light-emitting trading card cannot be confirmed, making it possible to create a surprise when the light is irradiated and the still image emits light.
[0014] In particular, according to the third invention, the middle layer includes an image film on which a still image consisting of a color with a wavelength different from the wavelength contained in the light irradiated by the organic EL is printed. For example, when the organic EL irradiates white light, the middle layer is provided with an image film on which a still image not containing white is printed. As a result, the color of the irradiated light and the color of the still image are combined, making it possible to emit the still image more clearly.
[0015] In particular, according to the fourth invention, the power supply cartridge supplies power to the light-emitting trading card. This makes it possible to supply power for causing the light-emitting trading card to emit light.

Embodiments for Carrying Out the Invention
[0017] An example of the light-emitting trading card 1 in the present embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an example of the light-emitting trading card 1 inserted into the power cartridge 2 in the present embodiment.
[0018] As shown in FIG. 1, the light-emitting trading card 1 is a card that is inserted into the power cartridge 2 through the insertion port 21, supplied with power from the power cartridge 2, and emits light using the supplied power. The light-emitting trading card 1 has the same area and thickness as a general card or a trading card, but is not limited thereto, and cards with any area and thickness may be used.
[0019] FIG. 2(a) is a diagram showing an example of the front surface 1a of the light-emitting trading card 1 in the present embodiment. FIG. 2(b) is a diagram showing an example of the back surface 1b of the light-emitting trading card 1 in the present embodiment. As shown in FIG. 2(a), the light-emitting trading card 1 is provided such that the image film 15 can be made visible from the front surface 1a, but is not limited thereto, and may be provided such that the image film 15 cannot be made visible from the front surface 1a. As shown in FIG. 2(a), the light-emitting trading card 1 may be provided with an electrode 11 for supplying power to the light-emitting trading card 1 on the back surface 1b. Further, the light-emitting trading card 1 may have an explanatory text or the like of the light-emitting trading card 1 described on the back surface 1b.
[0020] FIG. 3 is a diagram showing the configuration of the light-emitting trading card 1 in the present embodiment. The light-emitting trading card 1 includes a lower layer 1C including an organic EL (electro-luminescence) 14, a middle layer 1B provided above the lower layer 1C and including an image film 15, and an upper layer 1A provided above the middle layer 1B and including a translucent film 12 that transmits visible light. The light-emitting trading card 1 includes, for example, a lower layer 1C, a middle layer 1B provided on the upper surface of the lower layer 1C, and an upper layer 1A provided on the upper surface of the middle layer 1B. Further, the light-emitting trading card 1 may further include an arbitrary layer. The light-emitting trading card 1 may include, for example, a paper surface or the like on which an explanatory text or the like of the light-emitting trading card 1 is described on the lower surface of the lower layer 1C.
[0021] A light source 14 for irradiating light is provided in the lower layer 1C. Further, the lower layer 1C causes the light source 14 to emit light using the electric power supplied from the electrode 11. Further, the lower layer 1C may be provided with a light source 14 that irradiates light including light of an arbitrary wavelength or color. The lower layer 1C may be provided with a light source that irradiates light including, for example, white light. The light source 14 is, for example, an organic EL (electro-luminescence), but is not limited thereto, and may be any light source such as an inorganic EL (electro-luminescence).
[0022] An image film 15 on which a still image is printed is provided in the middle layer 1B. The image film 15 may be, for example, any filter that transmits light. The image film 15 may be, for example, a dimming filter of the PDLC (Polymer Dispersed Liquid Crystal) method. In such a case, for example, the image film 15 may operate the transmission of light by supplying electric power via the electrode 11.
[0023] The still image may be a still image depicting an arbitrary person, character, landscape, etc., but is not limited thereto, and may include any subject. The still image may be composed of a color having a wavelength different from the wavelength or color included in the light irradiated by the light source 14.
[0024] The upper layer 1A includes a translucent film 12 that transmits visible light. Any translucent film 12 may be used for the upper layer 1A. Alternatively, instead of the translucent film 12, a polarizing film (not shown) that removes reflected light may be used for the upper layer 1A.
[0025] FIG. 4 is a diagram showing a state in which the light-emitting trading card 1 in the present embodiment is inserted into the power cartridge 2. The power cartridge 2 is a cartridge for supplying power to the light-emitting trading card 1, as shown in FIG. 4. The power cartridge 2 supplies power to the light-emitting trading card 1 through the electrode 11 of the light-emitting trading card 1 inserted in the insertion direction S into the insertion port 21, for example. The power cartridge 2 is preferably, for example, of a portable size, but is not limited thereto and may be of any shape or size.
[0026] Next, the operation of the light-emitting trading card 1 will be described with reference to FIGS. 4 and 5. FIG. 5(a) is a diagram showing an example before the light-emitting trading card 1 in the present embodiment emits light. FIG. 5(b) is a diagram showing an example of the light-emitting trading card 1 that is emitting light in the present embodiment.
[0027] Before the light-emitting trading card 1 emits light, when the translucent film 12 is used, as shown in FIG. 5(a), the image film 15 is faintly reflected from the surface 1a. Thereby, it becomes possible to visually observe the image film 15 from the upper surface of the translucent film 12. Therefore, it is possible to check the image film 15 without irradiating light. Also, when the light-emitting trading card 1 uses a polarizing film (not shown), the light incident from the surface 1a and reflected by the image film 15 is removed, so that the image film 15 cannot be seen from the surface 1a. Therefore, since the still image drawn on the light-emitting trading card 1 cannot be checked until light is irradiated, it is possible to create a surprise when the still image is made to emit light by irradiating light.
[0028] As shown in Fig. 4, the light-emitting trading card 1 is inserted into the power supply cartridge 2 from the insertion direction S to be supplied with power and emit light. As a result, as shown in Fig. 5(b), the light emitted from the light source 14 causes the image film 15 to emit light for the light-emitting trading card 1.
[0029] Fig. 6 is a circuit diagram of the power supply cartridge 2. As shown in Fig. 6, the power supply cartridge 2 includes a power supply 23 and an electrode 22 that is connected to the power supply 23 and provided at the insertion port 21. When the electrode 11 of the light-emitting trading card 1 inserted into the insertion port 21 comes into contact with the electrode 22, power is transmitted to the light-emitting trading card 1 through the contacted electrodes 11 and 22.
[0030] Also, when using an image film 15 printed with a still image consisting of a color having a wavelength different from the wavelength included in the light irradiated by the light source 14, it becomes possible to emit light from the image film 15 more clearly. For example, when the light source 14 irradiates white light, by providing an image film 15 that does not contain white, the color of the irradiated light and the color of the still image are combined, and it becomes possible to emit light from the still image more clearly.
[0031] The operation of the light-emitting trading card 1 according to the embodiment of the present invention has been described above. As a result, it becomes possible to emit light from the still image included in the light-emitting trading card 1.
[0032] Although the embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention and are included in the invention described in the claims and its equivalent scope.
