In this state, the display main body 11, the display cover 12, the display mounting frame 13, And the back cover 14 is integrally assembled.

FIG. 7 shows the display portion 10 in an assembled state, and heads of a plurality of screws protrude from the display portion 10 in the screw-fastened portion. The heads of eight screws used for the positioning of the housing 20 and the display portion 10 among the heads of these screws are shown with reference numeral 41 a in FIG. 7 . Note that details of this positioning will be described later.

Next, the structure of the case 20 will be described with reference to FIG. 8 . FIG. 8 is a perspective view of the case 20 .

As described above, the box body 20 is a box-shaped member having a substantially square opening 20a formed on one side. Inside the housing 20, a control section 30 for controlling display contents of the display main body 11 is housed. The control unit 30 is fixed inside the housing 20 .

The ends of the first cable 15 and the second cable 16 drawn out from the above-mentioned cable passing hole 14a are electrically connected to the control unit 30 via a detachable connector not shown. The control unit 30 can supply power to the backlight of the display main body 11 via the first cable 15 . In addition, the control unit 30 can output an image signal to the display main body 11 via the second cable 16, and can control the content displayed on the display screen 11a.

As shown in FIG. 8 , inside the box 20 , a cable clamp 31 of a known structure capable of fixing the first cable 15 and the second cable 16 is attached to the control unit 30 . The cable clamp 31 is arranged at a position closer to the center of the opening 20 a than the connection between the first cable 15 and the second cable 16 and the control unit 30 , and holds the first cable 15 and the second cable 16 . The cable clamp 31 guides the middle portions of the first cables 15 and the second cables 16 through the opening 20a at a position sufficiently far from the edge of the opening 20a, and holds the first cables 15 and the first cables 15 and The second cable 16 is fixed to the control unit 30 .

As shown in FIG. 8, a flange 20b protrudes outward from the case 20 at a position corresponding to the edge of the opening 20a. The flange 20b is formed in a square shape along the opening 20a, and is formed with a constant width outside the opening 20a. On the inner edge of the flange 20b, a substantially square groove (not shown in the figure) is formed, and a packing (packing) 21 is attached to the groove. When the box body 20 is fixed to the display unit 10 , the sealing member 21 seals the opening 20 a of the box body 20 , and plays a waterproof function to prevent water from entering the box body 20 .

In the case 20 comprised as mentioned above, the 1st imaginary square (1st imaginary square P1 of FIG. 8) of substantially the same shape as the square formed by the flange 20b is conceivable. As shown in FIG. 1 , the first imaginary square P1 corresponds to (coincides with) the second imaginary square P2 in the display unit 10 described above.

A plurality of holes (recesses) 20c, 20c, . . . are formed in the flange 20b along the first imaginary square P1 defined as described above. In the present embodiment, as shown in FIG. 8 and the like, two holes 20 c are formed on each side so as to roughly divide each side of the first virtual square P1 into three equal parts. Therefore, the two holes 20c, 20c on one side of the first virtual square P1 are formed to coincide with the two holes 20c, 20c on the adjacent side when rotated 90° about the center of the first virtual square P1. Furthermore, in the present embodiment, the holes 20c, 20c, ... are arranged so that the positions of the holes 20c at every 90° rotation around the center of the first imaginary square P1 overlap. That is, the holes 20c, 20c, . . . are arranged in 90° rotational symmetry with respect to the center of the first imaginary square P1.

As shown in FIG. 8, a through-shaped insertion hole 20f is formed in the flange 20b. This insertion hole 20f is arrange|positioned at each vertex of the said 1st virtual square P1, and the midpoint of each side of the 1st virtual square P1. Therefore, the insertion hole 20f at the two ends and the midpoint of a certain side of the first imaginary square P1 is formed so that when the center of the first imaginary square P1 is rotated by 90°, it is aligned with the two ends of the adjacent side. And the insertion hole 20f of the midpoint is consistent. In addition, the insertion holes 20f, 20f, ... are arranged in 90° rotational symmetry with respect to the center of the first imaginary square P1.

Hereinafter, the operation of attaching the housing 20 to the display unit 10 will be specifically described. FIG. 9 is a perspective view showing a state in which the housing 20 is placed and positioned with respect to the display unit 10 with its back facing up. FIG. 10 is an enlarged view showing a circled portion indicated by a two-dot chain line in FIG. 9 . FIG. 11 is a cross-sectional view showing a positioning structure included in the display device 1 .

First, as shown in FIG. 7 , the display unit 10 is placed on a workbench or the like with the display screen 11 a facing downward (the rear cover 14 faces upward). In this state, the back side (mounting side surface) side of the display unit 10 is opposed to the opening side of the box body 20 so that the first imaginary square P1 specified in the box body 20 is opposite to the second virtual square P1 specified in the display unit 10 . The virtual squares P2 are overlapped, and the cabinet 20 is placed on the display unit 10 . In addition, as shown in FIG. 9, if the heads 41a of the eight screws arranged along the second imaginary square P2 on the side of the display unit 10 respectively enter (fit) into the screw heads 41a arranged along the first imaginary square P1 on the side of the box body 20. If there are eight holes 20c, the two imaginary squares P1 and P2 described above roughly coincide.

Here, the positioning structure realized by the head portion 41a of the screw and the hole 20c will be described in detail. In FIG. 10 , a portion surrounded by a two-dot chain line in FIG. 9 is shown enlarged, and the positioning screw 41 has the aforementioned head 41 a and a shaft 41 b linearly extending from the head 41 a. The head portion 41a has a larger diameter than the shaft portion 41b, and a groove (not shown) for inserting a tool such as a screwdriver (screwdriver) is formed at the top thereof. When the screw 41 is attached to the display unit 10, the head 41a protrudes toward the back side, but the head 41a has a shape in which the protruding length of the central part is large and the protruding length becomes smaller as it goes outward, that is, a shape in which the central part bulges out. . External threads corresponding to the internal threads of the aforementioned screw holes are formed on the outer peripheral surface of the shaft portion 41b. As the screw 41 , for example, known bind head screws, pan head screws, truss head screws, and round screws can be used.

As shown in FIG. 11 which is a cross-sectional view, the hole 20c has a shape that is deep in the center and becomes shallower toward the outside. In this embodiment, the outer peripheral portion of the hole 20c forms a tapered surface 20d with a slope of 10° based on the angle (0°) perpendicular to the plane of the flange 20b. Wherein, the slope of the tapered surface 20d is not limited to 10°, and may be larger or smaller than that. The depth of the central portion of the hole 20c is formed deeper than the protruding length of the head portion 41a of the screw 41, for example, by about 1 mm. The hole 20c has a semicircular U-shaped profile on the side close to the outer edge of the flange 20b when viewed in the depth direction of the hole 20c, and the side close to the inner edge of the flange 20b is plugged by the packing 21. . The hole 20c is formed slightly wider than the head 41a of the screw 41 when viewed in the depth direction, and can accommodate the head 41a of the screw 41 with play.

With the positioning structure configured as above, even if the position where the box body 20 is placed on the display unit 10 is slightly deviated, it is fixed by the heads 41a of the eight screws 41 arranged along the second imaginary square P2 on the display unit 10 side. With the curved surface and the tapered surfaces 20d of the eight holes 20c arranged along the first imaginary square P1 on the box 20 side, the box 20 is naturally guided to an appropriate position on the display unit 10 . Even if the deviation of the position where the housing 20 is placed on the display unit 10 is large, causing the flange 20b to ride on the head 41a of the screw 41 to create a gap between the display unit 10 and the display unit 10, in most cases, The position of the hole 20c and the head 41a of the screw 41 is not visually confirmed by peeping through the gap, but by slightly moving the housing 20 in an appropriate direction on the display unit 10, the above-mentioned guiding function can be exerted, and the The housing 20 is placed at an appropriate position on the display unit 10 without gaps.

In the state shown in FIG. 9 in which the position of the case 20 is roughly aligned with the display unit 10 as described above, it can be assembled on the back of the display unit 10 by fixing it with screws not shown using the insertion holes 20f and the screw holes 14g. Box 20.

In addition, the heads 41a of the eight screws 41 arranged along the second imaginary square P2 in the display unit 10 are 90° rotationally symmetric with respect to the center of the second imaginary square P2. In addition, the eight holes 20c arranged along the first imaginary square P1 in the box 20 are 90° rotationally symmetric with respect to the center of the first imaginary square P1. Therefore, in the present embodiment, no matter whether the display unit 10 is installed in the horizontal direction or the display unit 10 is installed in the vertical direction to the box body 20, the head 41a and the hole of the screw 41 can be used without any problem. Positioning (guide action) performed by 20c.

When it is desired to switch the posture of the display unit 10 between the landscape orientation and the portrait orientation, it may be as follows. That is, first, the display device 1 is placed on a workbench or the like with the display screen 11a facing downward. Next, the screws are removed from the insertion holes 20f to release the connection between the housing 20 and the display unit 10 . Next, the box body 20 is lifted up slightly to pull out the heads 41a of the screws 41 from the holes 20c, and the box body 20 is rotated by 90° around the center of the imaginary square P2 (P1). Thereafter, in the same manner as above, the case 20 is placed on the display unit 10 , and the heads 41 a of the screws 41 are inserted into the holes 20 c to perform positioning. Finally, by inserting screws into the insertion holes 20f and fixing them, the housing 20 and the display unit 10 are connected again.

In addition, the head 41a of the screw 41 inserted into the hole 20c of one side of the first imaginary square P1 enters the hole 20c of the adjacent side in association with the posture changing operation described above. In this way, the head 41a of the screw 41 can enter any one of the hole 20c on one side of the first imaginary square P1 and the hole 20c on the adjacent side.

In addition, as described above, the distance D1 between the screw holes 13b, 13b in one short side is slightly shorter than the distance D2 between the screw holes 13c, 13c in the other short side (D1<D2 ). Thus, the distance between the head 41a of the screw 41 (first shaft member) installed in the screw holes 13b, 13b and the head 41a of the screw 41 (second shaft member) installed in the screw holes 13c, 13c The distances between them are also different from each other. However, the difference in the distance is small enough to be absorbed by the play between the hole 20c and the head portion 41a. Therefore, regardless of the posture of the display unit 10 , positioning can be performed without problems.

In addition, the head 41a of the screw 41 installed in the screw hole 13b is arranged at a position slightly close to the midpoint of the side of the imaginary square P2, and the head 41a of the screw 41 installed in the screw hole 13c is arranged at a distance from the imaginary square P2. slightly further from the midpoint of the edge. Therefore, the movement range of the head 41 a of the screw 41 relative to the hole 20 c is limited when viewed as a whole of the display device 1 , and positioning can be performed with high precision.

In this way, in the display device 1 according to the present embodiment, it is possible to switch the posture of the display unit 10 with a simple operation. In addition, the orientation of the box 20 can be maintained and only the orientation of the display unit 10 can be changed, so there is no need to change the installation position of the support stand 40 relative to the box 20 or to change the layout of cables connected to the box 20 from the outside. Accordingly, the structures of the housing 20, the support stand 40, and the like are simplified, and the work of switching the orientation of the display unit 10 can be simplified.

As described above, the display device 1 of the present embodiment includes the housing (first housing) 20 and the display unit (second housing) 10 . The case 20 has a flange (mounting portion) 20b and a plurality of holes (recesses) 20c. The flange 20b is substantially square. The plurality of holes 20c are arranged on adjacent sides of the first imaginary square P1 and at positions that are 90° rotationally symmetrical with respect to the center of the first imaginary square P1, and each side of the first imaginary square P1 is set as Corresponds to each side of the flange 20b. In addition, this display unit 10 has a head portion 41 a (protruding portion) of the screw 41 . The head 41a of the screw 41 is configured to be on the side of the second virtual square P2 consistent with the first virtual square P1, and any one of the holes 20c on the adjacent side of the first virtual square P1 is Chimeric.

Thus, by changing the hole 20c for accommodating the head portion 41a of the screw 41, it is possible to attach the display unit 10 to the housing 20 in a horizontal direction or in a vertical direction. At this time, the display unit 10 and the housing 20 are arranged so that the heads 41a of the screws 41 enter (fit into) the holes 20c, thereby enabling easy positioning. Therefore, switching of the attitude of the display unit 10 (for example, switching between portrait and landscape) can be easily performed.

In addition, in the display device 1 of the present embodiment, the first housing is the housing 20 in which the opening 20 a is formed. The flange 20b is provided along the periphery of the opening 20a. The second box is the display unit 10 .

Thereby, by changing the hole 20 c for accommodating the head portion 41 a of the screw 41 , the direction in which the display unit 10 is attached to the housing 20 can be changed.

Furthermore, in the display device 1 of the present embodiment, the head portion 41 a of the screw 41 has a shape in which the protruding length of the central portion is large and the protruding length becomes smaller as it goes outward, as shown in FIG. 11 .

With such a shape of the head portion 41a of the screw 41, the head portion 41a of the screw 41 arranged in the vicinity of the hole 20c is easily naturally guided into the hole 20c, and positioning can be easily performed.

In addition, in the display device 1 of the present embodiment, the hole 20c has a shape that is deep in the center and becomes shallower toward the outside, as shown in the tapered surface 20d of FIG. 11 .

With such a shape of the hole 20c, the head portion 41a of the screw 41 disposed near the hole 20c is easily guided into the hole 20c naturally, and positioning can be easily performed.

In addition, in the display device 1 of the present embodiment, two holes 20c are arranged on each side of the first virtual square P1. Also, on each side of the second imaginary square P2, the heads 41a of the screws 41 corresponding to the holes 20c are arranged.

Thereby, when the cabinet 20 is attached to the display unit 10 , or when the display unit 10 is attached to the cabinet 20 , the four sides can be aligned regardless of which side of the first virtual square P1 is aligned. Therefore, efficient work can be realized.

In addition, in the display device 1 of the present embodiment, the hole 20c is formed wider than the head portion 41a of the screw 41 .

As a result, play is formed between the hole 20c and the head 41a of the screw 41, so that the head 41a of the screw 41 is guided (fitted) only by arranging the case 20 at a rough position relative to the display unit 10. The hole 20c further facilitates alignment.

In addition, in the display device 1 of the present embodiment, it is preferable to have the following configuration.
