Fig. 1 is a perspective view showing a display device according to a first embodiment of the present invention. The display device 1 shown in Fig. 1 includes a display main body 10 and a support member 30.

The display body 10 has a rectangular plate-like outer shape, and both sides of the display surface serve as display surfaces. The display main body 10 is held in a substantially vertical direction by a support member 30 disposed on the left and right as shown in FIG. The potential is supported. The display body 10 has a display surface covered by a transparent cover 11 having a rectangular plate shape. The photographic film 12 on which the desired pattern is drawn is accommodated inside the transparent cover 11 of each display surface in the table. In the display main body 10, the front surface film 12 of each of the front and back display surfaces is back-illuminated by a light-emitting surface to be described later, whereby the pattern of each of the positive image films 12 is displayed on the respective display surfaces via the transparent cover 11. As described above, the display device 1 of the present embodiment is a display device of a double-sided display type in which a desired pattern is displayed on both the front and back sides of the display main body 10 in the standing posture.

Here, the edge formed by the four sides of the transparent cover 11 of each display surface in the front surface is held by the frame member 13 having a rectangular shape. The transparent cover 11 held by the cover frame member 13 is opened and closed in the opening and closing directions D1 and D2 shown by the arrows in the figure, centering on the opening and closing axis of the upper side of the display main body 10 in the standing posture as will be described later. . Further, when the erecting film 12 is housed inside the display main body 10 and the aligned film 12 or the like is replaced, the transparent cover 11 is opened and closed.

Further, a lock member 14 that receives a predetermined operation and prohibits opening and closing of the respective transparent covers 11 is attached to a portion on the lower side of the display main body 10 in the standing posture of each of the cover frame members 13. By the lock member 14, for example, theft of the photographic film 12 or the like stored therein is prevented.

Fig. 2 is a view showing a cross section taken along the line A-A in Fig. 1 of the display device shown in Fig. 1. In addition, in FIG. 2, illustration of the support member 30 is abbreviate|omitted. Further, in the second drawing, the display body 10 is indicated by an arrow in the design plane direction Ax1 and the depth direction Ax2, respectively.

The surface light-emitting member 16 is a member having a rectangular plate shape and emitting light on both sides, and includes a light guide plate 161, a diffusion sheet 162, and a milk plate 163. The light guide plate 161 has a rectangular plate shape and receives light from the LED light source 15 at the end edge and spreads the light inside. In the present embodiment, the thickness of the light guide plate 161 is 5.0 mm. A milk plate 163 is attached to each of the front and back surfaces of the light guide plate 161 so as to sandwich the diffusion sheet 162 with the light guide plate 161. A pattern for diffusing light is engraved on the diffusion sheet 162, and light traveling inside the light guide plate 161 is diffused toward the outside of the front and back surfaces. Further, by the diffusion sheet 162, the phenomenon that the photographic film 12 on the opposite side is transferred to the front and back surfaces of the surface light-emitting member 16 disappears. The diffused light becomes milky white light by penetrating the breast plate 163. According to this configuration, the front and back surfaces of the surface light-emitting member 16 are such that the transfer phenomenon disappears and the surface is illuminated by the milky white light.

The frame member 17 for a surface light-emitting member holds the edge of the upper and lower sides of the edge formed by the four sides of the surface-emitting member 16 together with the LED light source 15 disposed in the vicinity of each edge.

Here, the LED light source 15 is arranged along the upper and lower sides of the light guide plate 161, and a plurality of them are arranged along the respective sides. In the present embodiment, a plurality of LED light sources 15 are arranged in one line along each side of the light guide plate 161. The plurality of LED light sources 15 accommodate the light emitting portions toward the respective sides of the light guide plate 161 in the two LED housings 19 that extend along the upper and lower sides of the surface light emitting member 16, respectively. Further, in the present embodiment, in the light guide plate 161 In the substantially orthogonal depth direction Ax2, a plurality of LED light sources 15 are housed in the LED housing 19 such that the center of each of the LED light sources 15 substantially coincides with the center of the light guide plate 161.

The upper and lower two LED housings 19 and the surface light-emitting members 16 are integrally coupled by two L-shaped members 20 extending along the upper and lower sides of the surface light-emitting member 16, respectively. The L-shaped member 20 has an L-shaped cross-sectional shape as shown in Fig. 2 . The outer surface of the LED housing 19 is then fixed to the inner wall surface of the L-shaped member 20. Further, the edge of the upper and lower sides of the light-emitting surface on the left side in the second light-emitting member 16 is fixed to the inner wall surface of the L-shaped member 20. By these subsequent fixings, the LED housing 19 and the surface light-emitting member 16 are integrally coupled.

Further, in the present embodiment, an example of the arrangement of the LED light sources is exemplified by being arranged along the upper and lower sides of the light guide plate 161, one row and one row. However, the arrangement form of the light source of the present invention is not limited to this embodiment, and may be, for example, an arrangement form of another example shown below.

Fig. 3 is a view showing another example of the arrangement of the light sources. In another example of the third embodiment, the thickness of the light guide plate 161' is thicker than the thickness (5.0 mm) of the light guide plate 161 of the first embodiment, and is 8.0 mm. On the other hand, the LED light source 15 of the first embodiment can also be used as a light source in this other example. However, in this other example, the LED light sources 15 are arranged along the upper, lower, two sides, two rows and two rows of the thick light guide plate 161' as described above. The arrangement of the two rows is such that the LED housing 19 is arranged in two rows along the edge of the light guide plate 161' in the depth direction Ax2. The LED housing 19 is for accommodating the LED light source 15 in one line. The boundary between the two rows of LED housings 19 substantially coincides with the center of the depth direction Ax2 of the light guide plate 161'. Each row of LED light sources 15 contributes to the illumination of the light-emitting surface of the LED light source 15 in each of the surface light-emitting members 16'. Further, in the depth direction Ax2, in order to compensate for the difference in size between the L-shaped member 20' and the surface-emitting member 16', the spacer 20a' is interposed therebetween. The description of the other example of the third figure is completed, and the description of the display device 1 of the first embodiment is returned.

In other words, the wall portion 172 is disposed so as to be offset from the outer edge direction Ax1 of the surface of the surface light-emitting member 16 . Further, the wall portion 172 extends in the depth direction Ax2. Further, a protruding wall 178 is protruded from the surface of the wall portion 172 on the side of the rectangular tubular portion 171, and the protruding wall 178 is spaced apart from the opening of the rectangular tubular portion 171 in the depth direction Ax2. On the side of the rectangular tubular portion 171 of the wall portion 172, the concave portion surrounded by the wall portion 172, the rectangular tubular portion 171, and the protruding wall 178 extends in the longitudinal direction. This concave portion serves as a second water passage 179a through which water that is immersed in the display main body 10 flows. In the frame member 17 for a surface light-emitting member, each of the second water passages 179a of the four frame members 17a and 17b is connected in a frame shape to form a second drain passage 179.

The second drainage path 179 is connected to the first drainage path 174 described above. The wall portion 172 is formed to be displaced from the first drainage channel 174 so as to be outward of the depth direction Ax2. Further, the wall portion 172 is formed to extend outward in the depth direction Ax2 of the second drainage path 179.

The surface light-emitting member holding portion 173 is a wall that protrudes from the surface of the wall portion 172 opposite to the side of the rectangular tubular portion 171 so as to be substantially orthogonal to the surface, and the surface light-emitting member holding portion 173 is connected and fixed. The L-shaped member 20 described above. The surface light-emitting member holding portion 173 is provided at a position where the boundary between the two C-shapes of the cross-sectional shape of the rectangular tubular portion 171 and the center of the depth direction Ax2 of the light guide plate 161 substantially coincide with each other. Further, in the surface light-emitting member holding portion 173, the L-shaped member 20 is fixed to the outer surface direction Ax1 at an interval of 6.5 mm between the wall portion 172 and the L-shaped member 20.

In the four frame members 17a and 17b constituting the frame member 17 for the surface light-emitting member, two hinge members 18 are fixed to the rectangular tubular portion 171 which is the upper frame member when the display main body 10 is in the standing posture. Each of the hinge members 18 is a slit that is screwed into the two C-shaped openings corresponding to the cross-sectional shape of the rectangular tubular portion 171 and extends in the longitudinal direction as will be described later. This screw-solid system is used by the connection jigs 175 and 176 which are connected to each other by the frame members 17a and 17b which comprise the frame member 17 for surface light-emitting members. The screwing of the hinge member 18 is described in conjunction with the frame members 17a, 17b.

The hinge member 18 is provided outside the frame of the surface light-emitting member frame member 17 and has an opening and closing shaft 181 that extends substantially parallel to the upper edge of the surface light-emitting member 16 when the display body 10 is in the standing posture.
