[0005]

[Action]

  Hereinafter, the usage procedure of the light viewer according to the present invention will be described.   The light viewer of the present invention can be used in two ways, for example, for slope and elevation. When using it as a slide, place the lid for the horizontal table on the desk or the like, If the upper slope / upper cover is opened, the viewer is attached to the slope / upper cover. The upper part of the main body is rotatably attached to the open side end of the slope / upright cover, The lower part of the viewer body is slidable on the inner bottom of the lid for the horizontal table. Slide the viewer body so that the slope / elevation screen is sloped or Stop and hold it at any position that makes it upright, and then, slope / upright screen Turn on the power of the light source elements arranged on the back side of the, and connect the screens for slopes and elevations to the screen. A moth, etc., may be placed on it for use.   When using it as a flat type, place it in a closed case on a desk, etc. Is placed so that the lid for the horizontal table is on the lower side, the upper surface is for slopes and elevations. The lid has a flat screen section, so you can use it for negatives or trace materials. Etc., and turn on the power of the light source element, the plane from the inside of the case The screen portion for use is illuminated with light.   Furthermore, this light viewer is a portable case such as an attach case. -Since it can be stored in the space, it can be easily carried after use. It can be done.   In addition, a pair of support poles are provided along both end portions of the front surface of the slope / upright screen portion. A pair of parallels that are provided opposite to each other and straddle the front surface of the screen portion on the support pole. Attach the mounting frame of the pole slidably in the vertical direction. There is a semicircular locking frame with a magnifying glass attached to the This allows the magnifying glass to move vertically and horizontally on the screen and at a distance from the screen. The separation is adjustable and the magnification can be changed. Furthermore, around the light source element The brightness can be secured by arranging an auxiliary member made of a material that reflects light. I am trying to do it.

[0006]

【Example】

  Hereinafter, the structure of the light viewer according to the present invention will be described as an example shown in the accompanying drawings. Therefore, in FIG. 1, one side is the slope / upright cover 1, and The other side is a portable case such as an attache case that can be used as the lid 2 for the horizontal table. Inside the case 3, an image for slopes and elevations made of a material such as milky white acrylic material on the front surface A surface portion 4 is provided, and a light source element 5 composed of a circle is provided on the back surface. The upper portion 6a of the viewer body 6 is provided on both sides of the open side end portion 1a of the slope / upper surface cover body 1. While being rotatably supported by a mounting shaft 7, the lower portion 6b of the viewer main body 6 is Provided with protruding shafts 8 slidable on guides 9 provided on both sides of the horizontal base lid body 2. In addition, the projecting shaft 8 is locked to an arbitrary number of projecting portions 10 provided at appropriate positions of the guide 9. Therefore, the screen portion 4 for slopes and elevations can be freely used for slopes or elevations. I am able to choose.   Further, in the opening 11 provided in the slope / upright cover 1, similarly, a milky white accompaniment is formed. It is made of a material such as rill material, and its surface is on the same plane as the above-mentioned slope / upright cover 1. A certain plane screen unit 12 is provided.   In addition, a pair of support poles are provided along both end portions of the front surface of the slope / upright screen portion 4. 13 are provided so as to face each other, and the support pole 13 straddles the front surface of the screen portion 4. Attach the mounting frame 15 of the pair of parallel poles 14 slidably in the vertical direction. In addition, the magnifying glass 16 can be freely attached to and detached from the parallel pole 14. And this fruit In the embodiment, as a structure for attaching and detaching the magnifying glass 16, as shown in FIGS. The magnifying glass 16 is attached to a semicircular locking frame 17 that can be locked to the parallel pole 14. This allows the magnifying glass 16 to be adjusted in multiple steps at different distances from the screen. The rate can be changed.   Further, in the above-mentioned embodiment, a arc line type fluorescent lamp is used as the light source element. I have used it, but there is no limit to the type of fluorescent lamp, and you can select a rod type or any other type. However, if the brightness is insufficient due to the use of fluorescent lights only, Around the main body 6, an auxiliary member provided with a material that reflects light in order to secure brightness. Auxiliary member, for example, silver plate, bellows type screen, winding screen, rotary type opening A window, closed window screen, or the like may be used, and in this embodiment, it is shown in FIGS. As shown in the figure, a pair of left and right bellows-type screens 18 are adopted, By operating the pull tab 19 that has come out, the screen is displayed on the back surface of the main body 6 when in use. 18 is extended, and when not in use, it is contracted on both sides of the main body 6 for storage. There is.   Further, as the light source element, instead of a fluorescent lamp, a backlight of a liquid crystal screen is currently used. 10 is a surface light source panel including a light source, a light guide layer, and a diffusion layer, and FIG. In the inside of the screen portion 20 made of a material such as acrylic material as shown in FIG. The optical fiber 22 connected to the screen is embedded so that the upper surface and the lower surface of the screen portion 20 are Means such as allowing the use of the surface may be adopted, and this optical fiber or When using the above surface light source panel, it is possible to secure the necessary amount of light. The auxiliary member becomes unnecessary.   In addition, Fig. 11 is used, for example, when you want to see unsorted slides immediately. The slide panel 23, which is convenient to use, shows the slide 2 on the transparent thin substrate 24. A holder 27 having a frame piece 26 capable of locking and holding 5 is formed, and From this part, a locking plate 29 having an opening 28 is projected, and the locking plate 29 is opened at the time of use. A stopper 30 provided with the mouth 28 on the slope / upright screen portion and also serving as a negative stopper The slide panel 23 can be locked and held by fitting it into the I made it so that the slide of can be set easily.   In the figure, 31 is a stand for a slide file, 32 is a holder, and 33 is An outlet of an outlet, 34 is a power cord, and 35 is a switch. Also, of this plan The power of the light viewer can be either AC or DC, and As shown in the embodiment, the upper part of the viewer main body is provided with the open side end of the slope / upright cover. Structure for rotatably mounting to the bottom part, the lower part of the viewer body is the inner bottom of the lid for the horizontal table The structure, etc., that allows the parts to slide so that they can be stopped is limited to the examples. Instead, various replacement means can be adopted.
