[0006]

[Embodiment of the invention]

 Embodiments of the present invention will be described with reference to the drawings based on typical examples. 1A is a front view of an embodiment of the present invention, FIG. 1B is an end view showing an aa 'end face in FIG. 1A, and FIG. 1C is an aa' end face when holding a film. FIG. As shown in FIG. 1A, the sharksten of the present invention is formed such that the illumination panel 40 is exposed on the front surface and the frame 20 of the housing 10 covers the periphery of the illumination panel 40 in a frame shape. . As shown in FIGS. 1A to 1C, a plurality of holding pieces 50 are provided as holding members in a gap 21 between the frame edge 20 of the housing 10 and the illumination panel 40. (Although a backlight device is provided on the back of the illumination panel 40, the illustration in the a-a 'end view and the enlarged view is omitted. The same applies hereinafter.)

[0007] In the present embodiment, the holding piece 50 is made of PETP generally called Mylar, which is a material having high tensile strength and tear strength, moderate elasticity, and excellent mechanical and chemical stability. A polyethylene terephthalate film was used. FIG. 2A is a plan view of a square piece of Mylar having a thickness of 0.2 mm and a size of 30 mm × 30 mm as a holding piece 50. Although the sheet is folded in two layers, as shown in FIG. 2B, the sheet is bent into a V-shape at an angle of about 30 degrees at the bent portion 52 due to the elasticity of the material. As shown in FIGS. 1A and 1B, the V-shaped holding piece 50 is arranged in the gap 21 between the illumination panel 40 and the frame edge 20 so that the bent portion 52 faces the open end 22 of the frame edge 20. When one half of the holding piece 50 is fixed to the inside of the frame edge 20 with an adhesive or the like, the other half of the holding piece 50 is pressed against the illumination panel 40 by its elastic force.

FIG. 2C is an enlarged top view of the aa ′ end face in FIG. 1A, showing a state before the film is attached to the shark casten, and FIG. 2D is an enlarged top view of the aa ′ end face in FIG. 1A. 2E shows a state in which the film 60 is inserted into the gap 21 while pressing the film 60 against the illumination panel 40. FIG. 2E is an enlarged top view of the aa ′ end face in FIG. FIG. 5 is a view showing a state where the holding piece is inserted into the holding piece 50. As shown in FIGS. 2C to 2E, when the film 60 to be attached to the shear caster is inserted into the gap 21 of the frame edge 20 while being applied to the surface of the illumination panel 40, the film 60 The film 60 is pushed between the panel 40 and the holding piece 50, and the film 60 is held by the lighting panel 40 by pressing the lighting panel 40 by the elastic force of the holding piece 50. The film 60 is held at one or a plurality of positions by the holding pieces 50, and furthermore, the surface attraction between the film 60 and the illuminating panel 40 acts to be stably held. The clamping piece 50 is formed by mounting a Mylar having a thickness of about 0.2 mm as described above, so that the moderate elasticity of the material enables smooth insertion and removal without damaging the film 60. It can be held on the panel 40. The film 60 to be attached to the shaka stainless steel is usually rectangular, and when one or two sides thereof are held by the holding pieces 50, a surface attraction force acts between the film 60 and the illumination panel 40, so that the entire surface of the film is exposed to light. It is held by the panel.

As shown in FIG. 1C, the opening edge 22 of the frame edge 20 on the front surface of the housing 10 is bent in the direction of the illumination panel 40, and the opening edge 22 of the frame edge 20 is fixed inside the frame edge 20. The holding piece 50 is formed so as to be closer to the illumination panel 40 than to the position of the bent portion 52 of the holding piece 50. By bending the opening end 22 of the frame edge 20 in the direction of the illumination panel 40, the width of the insertion hole of the gap 21 provided for inserting the film 60 between the illumination panel 40 and the frame edge 20 is reduced. It narrows toward the illumination panel 40 side. When the film 60 to be attached to the shelves is inserted from the opening end 22 of the frame edge 20 while being applied to the surface of the light panel 40, the film 60 comes into contact with the light panel 40 because the width of the insertion port becomes narrow. In this state, the film 60 is smoothly inserted between the illumination panel 40 and the holding piece 50 without being caught by the bent portion 52 of the holding piece 50, and the film 60 is transferred to the lighting panel 40 by the elastic force of the holding piece 50. Is held by the illuminated panel 40. In this embodiment, the gap 21 provided for inserting the film 60 between the illumination panel 40 and the frame edge 20 is a gap of about 3 mm, and the gap 21 of the film insertion port at the open end 22 of the frame edge 20 is provided. The gap is formed to be about 1.5 mm, and a V-shaped holding piece 50 having a thickness of 0.2 mm is provided, so that a 0.1 mm-thick dental x-ray film and a 0.2 mm-thick surgical It is possible to mount various kinds of photographic films having a thickness of 0.1 to 1 mm including an X-ray film.

FIG. 3 is an exploded perspective view showing the configuration of an embodiment of the present invention. In this figure, the film 60, the frame edge 20, the illumination panel 40 (the backlight device 41 is attached to the back surface), and the housing body 30 are shown in an exploded state, but in a completed state. In the figure, the illumination panel 40 is housed inside the housing body 30, and the frame edge 20 is screwed to the housing body 30. The housing body 30 and the frame edge 20 are formed by bending, drilling, pressing, or the like of a stainless steel plate having a thickness of 1 mm. The size of the housing 10 is about 25 cm in height, about 36 cm in width, and about 2 cm in depth. The illuminating panel 40 is a translucent (milky white) acrylic plate slightly smaller than the housing body 30, and has a back light device 41 in which a cold-cathode tube light source and an inverter power supply are integrally incorporated.

[Effect of the invention]

 The sharksten of the present invention has a neat design because a clip piece made of a polymer film is provided in the gap between the frame edge of the housing and the lighting panel as a holding member, so there is no need to provide a clip member outside the lighting panel. Realized and made the housing thinner. In addition, since a small piece of polymer film such as PETP polyethylene terephthalate is bent into a V-shape as the sandwiching member, the holding property of the film to be attached to the shakasten is excellent due to the moderate elasticity of the narrowing piece. In addition, the holding position can be freely adjusted without damaging the film, and the film can be detached. In addition, since the opening end of the frame edge is bent toward the lighting panel so as to be closer to the lighting panel than the position of the bent portion of the holding piece, the film is pinched when the film is inserted into the gap between the frame edges. It is smoothly inserted between the lighting panel and the holding piece without being caught in the bent part of the piece. It can also be used as a portable shakasten and used not only in consultation rooms but also in patients' rooms or bedside at home visits to explain to patients. It is also suitable for displaying general photographs and paintings as an illumination frame for interior decoration, and can be manufactured at a low price.
