DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. As is apparent from the plan view of FIG. 1 and the rear view of FIG. 2, a plurality of display units 1 are vertically and horizontally arranged so that a display surface A is formed on the front surface. On the front surface of the housing 2 of these display units 1, for example, light-emitting elements (not shown) such as discharge lamps are formed on the entire surface so as to form an expanded portion 3 arranged in a matrix and formed. Although not shown, a narrow portion 4 for accommodating circuit components connected to the light emitting element is formed in the rear portion. The width and height dimensions of the narrow portion 4 are set to values smaller than those of the display portion 3.
Therefore, the gap 5 is formed between the narrow portions 4 of the adjacent display units 1. A vertically long column 6 is inserted into the gap 5. These columns 6 are arranged with an arrangement pitch that is twice the arrangement pitch of the display units 1 in the horizontal direction.

Both sides of the column 6 and a plurality of display units 1 arranged in the vertical direction are connected by a crank-shaped connecting member 7. The coupling member 7 is fixed to the column 6 and the display unit 1 by screws 8. In addition, the adjacent pillar 6
The housings 2 of the display units 1 adjacent to each other are connected by a plate-shaped connecting member 9. These connecting members 9 are also fixed to the housing 2 with screws 8. In addition, stanchion 6
A columnar display power supply panel 10 for supplying electric power or a display signal to each display unit 1 is erected on the back side of the.

Consider the case where the display unit 1 located at the second position from the right side in FIG. First, the connection between the display unit 1 and the display power supply panel 10 is cut off, the coupling member 7 is removed from the column 6, the connection member 9 is removed, and the display unit 1 is pulled out. In this case, the housing 2 of the display unit 1
Since the width of the narrow portion 4 at the rear of the display unit 3 is narrower than the width of the display unit 3 at the front, the display unit 1 is pulled backward by a distance corresponding to the length of the display unit 3 in the depth direction. It is possible to move the display unit 1 and the connecting member 7 that have been pulled out halfway in this state without interfering with 1, and can be pulled out further rearward without interfering with the support column 6. The arrow B shown in FIG.
The drawing path of the display unit 1 at this time is shown. Conversely, when assembling the display unit 1, the display unit 1 can be inserted between other display units 1 by displacing the display unit 1 in the direction opposite to the arrow B.

In the assembled state, the peripheries of the front faces of the adjacent display units 1 can be brought close to each other. Also,
Since a plurality of display units 1 can be vertically arranged and coupled to both sides of the columns 6 arranged in the vertical direction, the support structure of the display units 1 can be simplified and the cost can be reduced. This is the effect corresponding to the invention of claim 1. Further, a narrow portion 4 is formed in the rear portion of the housing 2 of the display unit 1, and the pillar 6 is passed through the gap 5 between the narrow portions 4 of the adjacent housings 1 to form the housing 2 and the pillar 6.
And can be in close proximity. As a result, the depth dimension of the entire display device in the front-rear direction can be reduced.
Moreover, since the support pillar 6 can be brought close to the housing 2, the length of the coupling member 7 can be shortened.
The moment acting on the coupling member 7 due to the weight of the display unit 1 can be reduced. Therefore, the display unit 1 can be held horizontally.

By connecting the adjacent housings 2 between the columns 6 with the connecting member 9, the number of columns 6 can be reduced with respect to the number of the display units 1 arranged in the lateral direction. Therefore, the support structure of the display unit 1 can be further simplified. This is an effect corresponding to the invention of claim 2.

Next, a second embodiment of the present invention will be described with reference to FIG. The same parts as those in the above-described embodiment are designated by the same reference numerals and the description thereof is omitted (the same applies hereinafter). The plurality of struts 6 are arranged with an arrangement pitch that is twice the arrangement pitch of the display units 1, and are arranged behind the narrow portions 4 of the adjacent housings 2. Further, a vertically long support plate 11 extending toward the space between the adjacent housings 2 is connected to the center of the front surface of the support column 6 by means such as welding. These support plates 11
L-shaped connecting members 12 are fixed to both sides of the housing 8 by screws 8, and the back surface of the housing 2 is attached to the ends of the connecting members 12 by the screws 8.
It is fixed by. Further, the adjacent casings 2 between the adjacent columns 6 are connected by the connecting member 9.
In this way, the support plate 11 that supports the plurality of display units 1
Has a very high strength because it receives a force in a direction orthogonal to the plate thickness direction. As a result, the plate thickness of the support plate 11 is significantly smaller than the interval between the narrow portions 4 of the adjacent housings 2.

Consider the case where the display unit 1 located second from the right side in FIG. 4 is pulled out rearward in such a configuration. This work is performed from the support plate 11 to the connecting member 1.
2 is removed and the connecting member 9 is removed. In this case, since the width of the narrow portion 4 behind the housing 2 of the display unit 1 is narrower than that of the front display unit 3, pulling the display unit 1 backward interferes with the adjacent display unit 1. It is possible to move the display unit 1 and the connecting member 12 that have been pulled out halfway in this state without further interfering with the support column 6 and can be pulled out further rearward. An arrow B shown in FIG. 4 indicates a drawing path of the display unit 1 at this time. Conversely, when assembling the display unit 1, the display unit 1 can be inserted between other display units 1 by displacing the display unit 1 in the direction opposite to the arrow B.

In this case, a predetermined distance can be provided between the housing 2 and the column 6, and the plate of the support plate 11 extending toward the narrow portion 4 of the adjacent housing 2 can be provided. Since the thickness can be reduced, the display unit 1 and the coupling member 12 are moved along the side surface of the support plate 11 in the front-rear direction without interfering with the column 7 when the coupling member 12 is removed from the support plate 11. The possible distance can be increased.

The advantage of increasing the distance in which the display unit 1 is moved in the front-rear direction will be described. The housing 2 has a rectangular shape whose width dimension is larger than its height when viewed from the front. Therefore, after the display unit 2 is pulled out to the rear so as not to interfere with the display portions 3 of the other display units 1 that are adjacent to each other on the left and right, the casing 2 is removed from the display unit 2.
By turning 0 °, a margin should be formed between the vertical surface on the side surface of the housing 2 and the vertical surface on the side surface of the support column 6. This allows the housing 2 to be pulled out sufficiently rearward. However, on the other hand, the direction of the housing 2 is 90 °.
Since it has to be changed, it is possible to drop the display unit 1 carelessly.

According to the present embodiment, since the housing 2 does not interfere with the support plate 11 and the support column 6 even if the distance by which the housing 2 is moved backward is increased, the direction of the housing 2 is 90 °. Since it is not necessary to change the display unit 1, it is possible to prevent the display unit 1 from dropping and facilitate the assembly / disassembly work of the display unit 1. This is an effect corresponding to the invention of claim 3.

Further, a third embodiment of the present invention will be described with reference to FIG. The plurality of columns 6 are arranged with an arrangement pitch that is twice the arrangement pitch of the display units 1, and are provided upright behind the narrow portions 4 of the adjacent housings 2. Support arms 13 extending forward are provided on both sides of the pillar 6.
Are fixed by the screws 8, and the side surfaces of the narrow portions 4 of the support arms 13 of the housing 2 are fixed by the screws 8. The housings 2 adjacent to each other between the adjacent columns 6 are connected by a connecting member 9.

In such a structure, since the housing 2 and the support pillar 6 are coupled via the support arm 13 extending forward, a predetermined distance can be opened between the housing 2 and the support pillar 6. Therefore, in the state where the support arm 13 is removed from the support column 6, it is possible to increase the distance in which the display unit 1 can be moved in the front-rear direction without interfering with the support column 6. The advantage of this is the same as that of the above embodiment. This is an effect corresponding to the invention of claim 4.

Further, a fourth embodiment of the present invention will be described with reference to FIG. Reference numeral 14 is a support tool that supports the housing 2 of the display unit 1. That is, this support tool 14 is
The mounting plate 15 for supporting the lower surface of the mounting plate 15, the poles 16 provided upright on the mounting plate 15, and the grips 17 having both ends fixed to these poles 16. On the back surface of the housing 2 of each display unit 1, a locking piece 1 that is locked to the pole 16 is provided.
8 is formed.

In such a structure, when the display unit 1 surrounded by the surrounding display units 1 is pulled out or when the pulled-out display unit 1 is assembled, the hand interferes with the surrounding display unit 1, so that the detachable display unit 1 is detached. Both sides of the display unit 1 to be operated cannot be grasped by both hands and are unstable. Further, when the members for connecting or connecting and supporting the display unit 1 (the connecting member 8, the connecting members 7 and 12, the support arm 13 and the like) are removed in order to remove the display unit 1, the display unit 1 tilts by its own weight, which is not good. It is possible that it cannot be pulled out and removed. However, the support 1
The pole 16 of No. 4 is locked to the locking piece 18 of the display unit 1, the bottom surface of the housing 2 is supported by the mounting plate 15, and the grip 17 is gripped, so that the display unit 1 can be easily gripped with one hand. Can be attached and detached.

Further, if the mounting plate 15 is configured to hold the narrow portion 4 between the upper and lower portions, the display unit 1 is not tilted even if a member for connecting or connecting and supporting the display unit 1 is removed. It can be pulled out and removed.

[0027]

The invention according to claim 1 is as described above.
A narrow portion having a width dimension smaller than the width dimension of the front portion is formed in the rear portion of the display unit housing, and a plurality of support columns disposed near the narrow portions of the adjacent display units are provided. Since the support columns and the display unit are connected by the connecting member, the peripheries of the front faces of the adjacent display units can be brought close to each other, whereby the adjacent display units and the light emitting elements located in the end row are located. It is possible to reduce the influence on the displayed image by narrowing the interval of the display unit. Also, since it is possible to arrange and combine a plurality of display units in the vertical direction on both sides of columns vertically arranged side by side, It is possible to simplify the support structure and reduce costs.

According to a second aspect of the present invention, in the first aspect of the present invention, a plurality of support columns arranged with an array pitch that is twice the array pitch of the display units are provided, and adjacent display units are provided between adjacent support columns. Since the connection member for connecting the display units is provided, the number of columns can be reduced with respect to the number of display units arranged in the lateral direction, and thus the support structure of the display unit can be further simplified. .

According to a third aspect of the present invention, in the invention according to the first or second aspect, the dimension is smaller than the interval between the narrow portions of the adjacent display units which are coupled to the columns and extend toward the display unit. Since a vertically long support plate having a plate thickness and a connecting member for connecting and supporting the support plate and the display unit are provided, the distance between the adjacent display units is reduced as in the invention according to claim 1. It is possible to support the display unit with an inexpensive structure mainly composed of columns, and it is possible to open a predetermined distance between the display unit and the columns, and further, between the narrow portions of the adjacent display units. Since the extending support plate has a small thickness, the display unit and the connection member can be moved in the front-back direction along the side surface of the support plate without interfering with the support columns when the connection member is removed from the support plate. It is possible to increase the distance, which makes it possible to facilitate the assembly and disassembly operations of the display unit.

According to a fourth aspect of the present invention, in the first or second aspect of the present invention, there are provided support arms which are fixed to both sides of the column and extend forward. The support arms fix the display unit. Therefore, similarly to the invention according to claim 1, the distance between the adjacent display units can be reduced, and the display units can be supported by an inexpensive structure mainly of columns, and the support extending forward can be provided. Since the display unit and the support column are connected via the arm, a predetermined distance can be opened between the display unit and the support column, and thus, when the support arm is removed from the support column, the display unit and the support arm are provided. It is possible to increase the distance in which the display unit can be moved in the front-rear direction without interfering with the support, which facilitates the assembly / disassembly work of the display unit.
