It is sectional drawing cut | disconnected parallel. In both figures, the light source device 20 housed inside is omitted. The main body 11 is formed of a box, and its upper opening is covered with a glass plate 30 to form a substantially rectangular parallelepiped shape. The glass plate 30 is a plate made of translucent glass, and is preferably frosted glass or milky white tagron. However, the present invention is not limited to this, and a milky white resin sheet may be attached to a glass plate. In any case, it is preferable to use a material that causes little deformation such as expansion of the fluorescent lamp 21 due to heat. The thickness of the glass plate 30 is preferably about 3 mm.

On the other hand, the main body 11 is made of wood, and is composed of a side plate, four columns 17 for supporting the side plate, a bottom plate 15, and a glass plate fixing portion for fixing the glass plate 30 by framing the upper part of the side plate. It consists of 12. The side plate is assembled so that it can be inserted into the four columns. As a type of wood, paulownia, which has little hygroscopicity and a small amount of wood, is suitable. The side plate is erected perpendicularly to the bottom plate 15. Here, the side plates disposed in the longitudinal direction are referred to as first side plates 13, and the side plates disposed perpendicular to the first side plates are referred to as second side plates 14.

The glass plate fixing portion 12 is provided on an upper peripheral portion of the main body 11 formed by the first side plates 13, 13 and the second side plates 14, 14. In the glass plate fixing portion 12, a receiving portion 12 a on which the glass plate 30 is placed protrudes toward the inside of the main body 11. Further, on the upper end surface of the receiving portion 12a, a receiving surface 12b formed of a flat surface parallel to the bottom plate 15 is provided at a uniform height from the bottom plate 15 over the inner periphery of the main body 11.

In the glass plate fixing portion 12, a peripheral portion 12d is provided around the receiving surface 12b so as to be higher by the same step difference h as the thickness of the glass plate 30. Further, the size and shape of the glass plate 30 are set to be substantially the same as the shape and size formed by the inner edge of the peripheral portion 12d.

When fixing the glass plate 30 to the main body 11, the glass plate 30 is placed on the receiving surface 12 b from above the main body 11 as shown in FIG. 2 (a), and shown in FIGS. 2 (b) and 3. Fix so that As a result, the glass plate 30 is fitted and fixed in the frame formed by the peripheral portion 12d, and the peripheral portion 12d and the surface of the glass plate 30 are located on the same plane. Further, the glass plate 30, the peripheral portion 12d, and the outer edge 12c which is a corner of the glass plate fixing portion 12 in the upper part of the main body are all formed of a smooth surface without irregularities.

Next, the glass plate holder 50 will be described with reference to FIGS. FIG. 6 is a perspective view showing a state where the glass plate retainer 50 is attached to the main body 11. FIG. 7 is a schematic view showing an operation method of the glass plate retainer 50. The two glass plate holders 50, 50 are made of wood made of the same material as the main body 11, and include a holding portion 51 obtained by cutting a wooden plate into a bar shape, and two supporting portions 52. The shape is such that the support portion 52 is connected to both ends of the holding portion 51 in an L-shape, and the whole is formed in a U-shape.

At the center of the distal end of the support portion 52, there is provided a fixed shaft engaging portion 53 which is cut out in a square shape in cross section and formed in a concave shape, and further, from near the center of the support portion 52 toward the pressing portion 51. A support shaft hole 54 cut into a rectangular shape is provided. The fixed shaft engaging portion 53 is set to a size into which a first fixed shaft 57 and a second fixed shaft 58 described later are fitted. Further, the size of the support shaft hole 54 is set with an allowance so that the support shaft 55 described below can pass through and the support shaft 55 can move in the longitudinal direction of the support shaft hole 54.

The glass plate retainer 50 having such a shape is disposed so as to straddle two opposing first side plates on both sides thereof. For this purpose, the distance between the two supporting portions 52 of the glass plate retainer 50 is set such that the surfaces of the pillars 17 that face in the same direction as the first side plate sandwich the second side plate. The distance is set to be substantially the same as the facing distance.

The method of fixing the glass plate retainer 50 to the main body 11 is as follows. In the two support portions 52, the screw as the support shaft 55 is passed through the support shaft hole 54 through the washer 56, and It is fixed by screwing. A metal anchor for receiving the screw is provided at the position where the column 17 is screwed, thereby maintaining the durability of the wooden column 17. The glass plate retainer 50 thus fixed is movable around the support shaft 55 by a distance in the longitudinal direction of the support shaft hole 54 as shown in FIG.

As shown in FIG. 7, a first fixed shaft 57 is disposed below the screwed position of the two support shafts 55, and a second fixed shaft 57 is provided above the first side plate 13 of the main body 11. A fixed shaft 58 is provided. The first fixed shaft 57 is attached to the fixed shaft engaging portion 53 in a state where the support portion 52 is lowered vertically to the bottom plate 15 and the pressing portion 51 is fixed by sandwiching the glass plate 30 with the receiving surface 12b. It is positioned to fit. On the other hand, the second fixed shaft 58 removes the pressing portion 51 from the glass plate 30 and rotates about the support shaft 55, and is fitted into the fixed shaft engaging portion 53 with the pressing portion 51 in contact with the support 17. Is positioned. In particular, as shown in FIG. 7, it is preferable to dispose the second fixed shaft 58 so that the support portion 52 is fitted in the fixed shaft engaging portion 53 in a state of being parallel to the bottom plate 15.

Next, a description will be given of a method of using the front mounting table 10 having the above configuration. When the book paper 40 is viewed through, the two glass plate holders 50 hold both sides of the glass plate 30 placed on the glass plate fixing portion 12 from above with the holding portions 51 and sandwich the glass plate holder 30 with the receiving surface 12b. State. At this time, since the fixed shaft engaging portion 53 provided on the support portion 54 engages with the first fixed shaft 57, the glass plate holder 50 is fixed at that position, and the glass plate 30 is prevented from falling. . Further, since the two fluorescent lamps 21 are arranged in parallel in the longitudinal direction of the main body 11, it can be energized to illuminate the entire surface of the glass plate 30.

Although the shape of the book paper 40 varies, for example, a long book paper 40 that is displayed as a hanging object is transferred over the surface of the glass plate 30 as shown in FIG. The book paper 40 is placed on the glass plate 30 while being arranged between the glass plate holders 50 so that the width direction of the book paper 40 can be accommodated. Then, since the book paper 40 is transmitted by the light source device 20 by the area of the glass plate 30, the entire book paper 40 can be seen through by moving the book paper 40 with respect to the glass plate 30. At this time, since the glass plate holder 13 prevents the glass plate 30 from falling, the translucent table 10 for surface mounting may be installed obliquely and adjusted to an angle that facilitates the work. Since the glass plate retainer 13 is fixed to the main body 11 and is integrated therewith, there is no possibility of being lost. In addition, since the glass plate 30 is securely fixed by the receiving portion 12a, it is possible to perform an operation such as attaching a reinforcing tape to a position of a wound on the glass plate 30 while transmitting the book paper 40. , Work efficiency can be improved. Further, since it is not necessary to mark the position of the scratch unlike the conventional case, the book paper 40 is not damaged without any darkness.

The paper 40 in FIG. 4 is in contact with the surface of the glass plate 30 at the peripheral edge 12 d and the upper outer edge 12 c of the main body 11, but the glass plate 30, the peripheral edge 12 d and the outer edge 12 c have smooth surfaces. Since it is formed, the book paper 40 is not damaged. If the peripheral edge 12d and the outer edge 12c become uneven due to long-term use or an external injury, the main body 11 is made of wood. Can be.

In the case of a large-sized book paper 40, it is preferable to remove the glass plate holders 50 on both sides from the surface of the glass plate 30, put the book paper 40 so as to cover the main body 11, and transmit the paper. At this time, as shown in FIG. 7, the glass plate retainer 50 is moved in the direction indicated by the arrow. First, the glass plate retainer 50 is lifted upward, and the fixed shaft engaging portion 53 is disengaged from the first fixed shaft 57. Then, the pressing portion 51 is rotated so as to move in both sides of the main body. By pressing the pressing portion 51 in the direction of the arrow in the direction of the arrow at the position where the fixed shaft engaging portion faces the second fixed shaft, the fixed shaft engaging portion 53 is Engage.

In this way, the holding portion 51 is removed from the surface of the glass plate 30 and fixed on both sides of the main body 11. By removing one or both of the two glass plate holders 50 from the glass plate 30 as needed, it is possible to cope with the book paper 40 of various sizes. Further, since the glass plate retainer 50 removed from the glass plate 30 is fixed in parallel to the bottom plate 15 and is in contact with the support 17, there are few portions protruding from the main body 11, and the paper 40 hanging down from the glass plate 30 is removed. Does not hurt by being caught.

Similarly, when the glass plate 30 needs to be removed, such as when the fluorescent lamp 21 is replaced, the glass plate holder 50 is moved in the direction indicated by the arrow in FIG. 7 to remove the glass plate 30 upward. It is done in. After replacing the fluorescent lamp 21, the glass plate 30 is installed again, and the glass plate holder 50 is traced in the opposite direction of the arrow, so that the front mounting table 10 can be used again. .

FIG. 5 shows a structure in which a detachable ribbon 31 is attached so that the glass plate 30 can be easily detached in consideration of usability. The detachable ribbon 31 is a ribbon-like member that is fixed to the inner wall surface of the first side plate 13 or the second side plate 14 at a fixing portion 31 a and extends outward from the main body 11. When the glass plate 30 is placed and fixed on the main body 11 while keeping the removal ribbon 31 along the glass plate fixing portion 12, the removal ribbon 31 is sandwiched between the receiving surface 12b and the glass plate 30. Since the mounting table 10 is used in this state, it is desirable that the detachable ribbon 31 be formed of a ribbon as thin as possible so as not to affect the surface of the glass plate. The number and position are not limited.

When it is desired to remove the glass plate 30 from the main body 11, the glass plate 30 is lifted by pulling the removal ribbon 31 upward, so that the glass plate 30 can be easily removed. In addition, if the removal groove 32 as shown in FIG. 6 is provided, the removal of the glass plate 30 is further simplified. The removal groove 32 is formed by cutting off the inner edge of the peripheral portion 12d to a depth of about 3 mm so that a finger can be inserted. It is effective if two grooves are provided, but the number and position are limited. is not. When removing the glass plate 30, the glass plate 30 can be easily removed from the main body 11 by lifting the removal ribbon 31 while inserting a finger into the removal groove 32.
