By the way, the touch panel 15 tends to be difficult to operate from an oblique direction. Therefore, in the embodiment of the present invention, the display unit 11 can be swung by the connecting mechanism 28 described later so that the touch panel 15 can be operated from the front, and the orientation of the display unit 11 having the touch panel 15 can be adjusted. In particular, in an embodiment of the invention, a portion of the device 25 that constitutes the electrical circuit for the thin display 14 is located on the column 16. This allows
Since the display unit 11 can be made lightweight, for example, when the position of the display surface 10 can be adjusted by the connecting mechanism 28, the position can be easily adjusted with a light force.

Further, the display unit 11 can be downsized, for example, the dimension in the front-rear direction can be thinned to improve the appearance. Moreover, since the device 25 is arranged on the column 16, compared with the case where the device 25 is arranged on the base 17,

In addition to 2, it is also conceivable to use the control circuit 18 and the interface 19 described above.

In particular, the electric circuit arranged on the column 16 is
The power supply circuit 22 is preferable. That is, since the power supply circuit 22, which tends to be heavy, can be arranged outside the display unit 11, the display unit 11 can be effectively reduced in weight. Further, a member for attaching the power supply circuit 22 can be omitted or simplified, which contributes to downsizing and weight saving. Even if the power supply circuit 22 may generate noise, such a power supply circuit 22 can be kept away from the display unit 11, so that the level of noise from the power supply circuit 22 in the display unit 11 can be reduced. Therefore, it is possible to suppress the adverse effect caused on the display unit 11 due to the noise from the power supply circuit 22. For example, it is possible to prevent unintended lines from being displayed on the thin display 14. Further, since the member for suppressing the adverse effect of noise can be simplified or omitted in the display unit 11, the display unit 11 can be further downsized and lightened, and the cost can be reduced. Furthermore, the temperature of the display unit 11 can be prevented from rising due to the heat generated from the power supply circuit 22.

The column 16 has a main body having a groove-shaped cross section, and a cover attached to cover the rear portion of the main body. The main body and the cover are made of sheet metal. A storage chamber is defined inside the groove of the main body, and an electric circuit is stored and fixed in the storage chamber. The periphery of the electric circuit is covered by the main body and the cover. An opening is formed in the upper portion of the main body, and an electric wire 23 from the power supply circuit 22 extends into the display unit 11 through the opening. The lower portion of the main body is fixed to the bottom portion 34 of the base 17.

An electric wire 24 is housed inside the column 16. The electric wire 24 connects the circuit boards of the control circuit 18, the detection circuit 27, and the circuit 20 of the interface 19 to each other. From the upper part of the pillar 16, the electric wires 23 and 24 are introduced into the display unit 11 through the vicinity of the connecting mechanism 28. In addition, the pillar 16

The base 17 includes a bottom portion 34 that is a plate-shaped sheet metal molded product that can be placed along the installation surface, a cover 35 that is a resin molded product that can openably cover the upper portion of the bottom portion 34, and a bottom portion 34. It has a housing space 36 that is partitioned between the cover 35 and the connector 21 and the like.
The bottom part 34 partitions the lower part of the housing space 36, and the cover 35 partitions the upper part and the lateral side of the housing space 36. Accommodation space 3
6 includes an interface 19 and this interface 1
9 and a part of the connection cable 3 connected to 9. Please refer to FIG. 4 and FIG.

The bottom portion 34 and the cover 35 are detachably engaged with each other. Remove the cover 35 from the bottom 34,
The accommodation space 36 is opened, and the connectors 5 and 21 are connected or separated. A known method can be used as a specific method of forming the bottom portion 34 and the cover 35. The housing space 36 has a connector 21 of the interface 19 for an external device, a part of the counterpart cable 3 that is detachably connected to the connector 21, that is, the connector 5, and has a predetermined length near the connector 5. The electric wire 4 part is accommodated.

As described above, since the pair of connectors 5 and 21 connected to each other can be housed in the inner depth of the base 17,
It is possible to prevent adverse effects due to dust, etc. from the outside. For example, it is possible to prevent dust and the like from adhering to the outer surface and making the appearance unfavorable. Moreover, both connectors 5, 21 and cable 3
Since a part of the electric wire 4 is accommodated in the base 17, it is not necessary to secure a large space outside the base 17 for connecting the connectors 5 and 21 to each other. As a result, for example, it is possible to prevent an unexpectedly large space around the base 17 when the display device 1 is installed, and therefore, it is possible to avoid extra work for arranging the cable 3. Easy to install.

Moreover, since the pair of connectors 5 and 21 connected to each other are housed in the housing space 36, the pair of connectors 5 and 21 move along with the display unit 11 when the orientation of the display unit 11 is adjusted. Can be prevented and the connector 5,21
It is possible to prevent excessive force from being applied between them. As a result, for example, even if the connector 5 is not provided with a retaining structure, it is possible to prevent the connector 5 from being accidentally detached. Further, it is possible to prevent contact failure.

The base 17 has a plurality of mounting portions 37 to 39 for detachably mounting the electric wire accommodated in the accommodating space 36 to the base 17. These mounting portions include first and second mounting portions 37 and 38 for mounting the electric wire 4 of the counterpart cable 3 to the base 17, and a third mounting portion 39 for mounting the power supply line 26. . The first and third mounting portions 37, 39 are located on the left and right sides of the rear edge of the base 17, and are arranged at positions corresponding to the openings 40 of the base 17 for leading out electric wires. The second mounting portion 38 is arranged at a substantially central portion of the base 17, and fixes the electric wire 4 at an intermediate portion between the connector 5 and the first mounting portion 37. Each mounting part 37-3
Reference numeral 9 denotes a band-shaped member that surrounds the corresponding electric wires 4 and 26 from the surroundings and holds the wires in a close contact state, a screw for fixing the band-shaped member to the base 17, and a screw hole into which the screw is screwed. And a fixed portion that is fixed.

As described above, since the position of the electric wire 4 is regulated by mounting the electric wire 4 on the stand 12 by the mounting portions 37 and 38, it is possible to move the stand 12 or the cable 3 when the display device 1 is installed. Also, it is possible to further suppress the application of unreasonable force between the connectors 5 and 21 via the electric wire 4 of the connection cable 3. The interface 19 constitutes a connector unit 29 corresponding to the plurality of connection cables 3. The connector unit 29 includes a plurality of connectors 21 corresponding to a plurality of counterpart cables 3.
And a single circuit board 41 described above on which the plurality of connectors 21 are mounted.

The plurality of cables 3 of the other party are, for example,
A plurality of, for example, two cables 3 for the thin display 14 and one cable 3 for the touch panel 15 are included. The interface 1 is provided on the circuit board 41.
A circuit for the thin display 14 of 9 and a circuit for the touch panel 15 of the interface 19 are integrally formed. As described above, since the connector unit 29 needs only one circuit board 41, the number of parts of the circuit board 41 and parts such as screws for fixing the circuit board 41 can be reduced, and as a result, the component cost and the assembly cost can be reduced. Contribute to cost reduction.

Furthermore, since the circuit board 41 of the connector unit 29 can be integrally provided with an electric circuit for connecting external devices to each other, the convenience of the display device 1 can be improved by such an electric circuit. At the same time, the structure can be simplified. For example, the connector unit 29 has a connector 42 for connecting external devices. The connector 42 is arranged to face the outside through an opening on the side surface of the cover 35 of the base 17. Accordingly, the cable for connecting the external devices, which is assumed to be frequently attached and detached, can be easily connected from the side while the cover 35 is still attached to the bottom portion 34.

In particular, since the connector 42 is arranged so as to face the side surface of the base 17, the stand 12 can be used at the time of connection work.
It is not necessary to rotate the hand to the rear of the stand, and it is not necessary to secure a space for connecting the front and the rear of the stand 12. as a result,
Connection work is easy. In the above description, the case where the accommodation space 36 is divided into the base 17 has been described, but the case where the accommodation space 36 is divided into the support columns 16 is also conceivable. Similarly, the mounting portion 37 ~
39 may be provided on the column 16. Even in this case, the above-described effects can be obtained.

Further, as in this embodiment, the accommodation space 3
When 6 is divided into the base 17, there is a space in the accommodation space 36, which is preferable. This is because when the rear surface 31 of the display unit 11 is supported by the column 16 of the stand 12, the root portion 47 of the column 16 of the stand 12 is supported.
Is attached to the rear portion 43 of the base 17, and the front portion of the base 17 becomes an empty space. Therefore, the housing space 36 is defined in the base 17, and the connector unit 29
Are arranged in front of the base portion 47 of the support column 16 in the base 17. As a result, the empty space in the front part of the base 17 can be effectively used, so that the base 17 can be prevented from becoming large in the front-rear direction and the appearance can be improved.

Further, the connector unit 29 is attached to the base 17
It is also conceivable to place it in the rear part 43, but in this case,
It is necessary to secure a space for the connector unit 29 at the rear of the column 16, and it is assumed that the base 17 becomes large in the front-rear direction. The connector unit 29 is the base 1
7 is arranged so as to be biased only to the right side portion as one side.
Each connector 21 is arranged toward the left side, and the connector 5 of the counterpart cable 3 is connected from the left side as the other side. The electric wire 4 of the counterpart cable 3 is led out from the opening 40 on the rear surface of the rear portion 43 of the base 17. The opening 40 and the connector unit 29 are arranged side by side on a diagonal line of the base 17 in a plan view. Note that the left and right relationships may be interchanged.

As a result, as compared with the case where the connector unit 29 and the cable 3 are arranged on only one of the right side and the left side, there is more space for guiding the cable 3, so that the cable 3 which is usually hard to bend is not required. The radius of curvature can be increased, and the electric wire 4 of the cable 3 can be accommodated in the base 17 without difficulty. As a result, the connectors 5, 21
It is possible to further prevent excessive force from being applied between them. Moreover, since the cable 3 and the connector unit 29 are arranged side by side, the space required for this can be reduced in the front-rear direction, and the base 17 in the front-rear direction can be reduced.
Can be prevented from increasing in size.

At the bottom portion 34 of the base 17, the connector 5 of the counterpart cable 3 connected to the connector unit 29 is connected.
A notch 44 is formed at a position corresponding to. Thereby, the interference between the bottom portion 34 and the connector 5 can be prevented, and the cable 34 can be easily connected without the bottom portion 34 interfering. Moreover, the base 17 can be made lighter, and the base 17 can be made thinner along the vertical direction. Also, the notch 44
When the connector 5 is opened to the peripheral edge of the base 17, the connector 5 is accommodated in the accommodation space 36 corresponding to the notch 44 from the opening direction.
Since it can be moved in and out, it is possible to easily connect the connectors 5 and 21 to each other. In particular, when the opening direction of the notch 44 is forward, the portions of the bottom portion 34 on both sides of the notch 44 can be formed to be long in the front-rear direction, and the decrease in rigidity of the base 17 can be suppressed.

At the peripheral edge of the notch 44, as a reinforcing portion for reinforcing the bottom portion 34, a standing plate portion 45 which is arranged on the right side of the notch 44 and integrally formed with the base 17 in a cut-and-raised shape, and the left side of the notch 44. And a folded-back plate portion 46 formed integrally with the base 17 in a folded shape. The standing plate portion 45 functions as a cover of the interface 19,
The side on which the connection cable 3 is mounted covers the connector unit 29 and has an opening for connecting the connectors 5 and 21.
The folded-back plate portion 46 prevents an edge from being generated in the peripheral portion of the cutout 44, and prevents the connection cable 3 from being damaged.

Further, in the embodiment of the present invention, the orientation of the display section 11 with the touch panel 15 can be adjusted so as to be swingable vertically and horizontally by the connecting mechanism 28. Accordingly, even when the user is diagonally in front of the display device 1, by moving only the display unit 11 without moving the entire display device 1 together with the stand 12, the touch panel can be viewed from the direction facing the display surface 10. 15 can be operated reliably. Further, it is preferable to apply the connecting mechanism 28 to the display device 1 without the touch panel 15, and the display surface 10 can be easily seen. In particular, a liquid crystal display may be difficult to see from an oblique direction, but the present invention is preferable because such a liquid crystal display can be easily seen.

The connecting mechanism 28 has a vertical swing mechanism 51 that allows the display unit 11 to swing vertically, and a horizontal swing mechanism 52 that allows the display unit 11 to swing horizontally. Both swinging mechanisms 51 and 52 are interposed in series between the upper end of the column 16 and the rear surface 31 of the display unit 11. Thereby, the connection mechanism 28 can adjust the orientation of the display surface 10 vertically and horizontally. The vertical rocking mechanism 51 is arranged so that the display unit 11 is arranged around the first rocking axis C1 extending in the left-right direction so that the display surface 10 is oriented vertically.
By rotating, the orientation of the display unit 11 can be adjusted up and down, and the display unit 11 is interposed between the rear surface 31 of the display unit 11 and the left-right swing mechanism 52. The adjustment range of the swing angle is, for example, an angle range in which the display surface 10 faces upward, 20 degrees in the upward direction, and 10 degrees in the downward direction, with the display surface 10 facing the front. To be done.

The left / right swing mechanism 52 rotates the display portion 11 around the second swing axis C2 extending in the vertical direction so that the display surface 10 is directed to the left / right, and thus the display portion 11 is rotated.
Can be adjusted to the left and right, the vertical swing mechanism 51 and the support 16
Intervenes between the upper end of the. The adjustment range of the swing angle is, for example, an angle range of 30 degrees on both sides of the state where the display surface 10 faces the front. Further, the first swing axis C1 for swinging up and down is arranged closer to the display surface 10 than the second swing axis C2 for swinging left and right. As a result, the display unit 1 when swinging up and down
The influence of the weight of No. 1 can be reduced and the rocking can be facilitated.

And the second swing axis lines C1 and C2 in front view.
It is placed in the approximate center of 0. Thereby, the touch panel 1
During 5 operations, the maximum value of the arm length of the moment around both swing axis lines C1 and C2 due to the operating force can be suppressed, the moment due to the operating force can be suppressed, and the deflection of the display unit 11 caused by this moment can be suppressed. Can be suppressed. Therefore, it is possible to prevent an operation error due to the shake, and it is not necessary to wait for the shake to subside, and it is easy to operate the touch panel 15.

Further, by supporting the display unit 11 at the central portion along the vertical direction, the display unit 11 is supported by the support 1 at the lower portion thereof.
Since the pillar 16 can be made longer than in the case of being supported by 6, it is possible to secure a large space available for arranging the electric circuit on the pillar 16 and to easily arrange the electric circuit. That is,
It is easy to work when assembling the electric circuit into the column 16, and the degree of freedom in the layout of the electric circuit can be increased. As shown in FIGS. 6 to 8, the connecting mechanism 28 includes a first bracket 53 fixed to the rear surface 31 of the display unit 11 and the first bracket 53.
Second bracket 55 that is connected to the bracket 53 of FIG.
And a third bracket 57 which is connected via a pair of bolts 56. The third bracket 57 is the post 1
It is fixed to the upper end of 6.

The first bracket 53 includes a pair of side plates 61 and 62 that are spaced apart from each other and face each other and are arranged in the left-right direction.
The connecting plate 63 connects these side plates. The second bracket 55 includes a pair of side plates 71 and 72 that are spaced apart from each other and arranged in the left-right direction, and a pair of side plates 73 that are spaced apart from each other and arranged in the up-down direction.
Connection plate 75 connecting these two pairs of side plates 71 to 74
Have and. A pair of side plates 71, 72 and a pair of side plates 7
3, 74 are arranged on the opposite sides of the connection plate 75.

The third bracket 57 includes a pair of side plates 81, 82 which are spaced apart from each other and face each other and are arranged in the vertical direction.
The connection plate 83 connects the side plates 81 and 82 to each other.
The pair of side plates 61, 62 of the first bracket 53, and the second
The pair of side plates 71, 72 on one side of the bracket 55 and the pair of bolts 54 connecting the side plates together constitute a vertical swing mechanism 51. The bolts 54 are arranged so as to extend in the left-right direction, penetrate the corresponding side plates and washers of both brackets 53 and 55, and have nuts 58 screwed into them. The axis of both bolts 54 becomes the first swing axis C1.

The other pair of side plates 73, 74 of the second bracket 55 and the pair of side plates 8 of the third bracket 57.
1, 82 and a pair of bolts 56 that connect these side plates together form a left-right swing mechanism 52. Each bolt 56
Are arranged so as to extend in the vertical direction, and both brackets 5 are
5, 57 through the corresponding side plates, washers, etc.
Is screwed in. The axis of both bolts 56 becomes the second swing axis C2. Each swinging mechanism 51, 52 of the connecting mechanism 28
Then, the pair of side plates of one of the brackets are on the same side in the extending direction of the swing axis, and the pair of side plates of the other bracket respectively correspond to the other side of the bracket through the washers 59 while the bolts 54 and 56 as the connecting members pass through. I am trying to face it.

The washer 59 is a bracket 5 made of metal.
In order to prevent dust from being generated by rubbing 3, 55, 57 with each other, the metal bracket 53,
It is provided in order to stabilize the frictional force by suppressing the weakening of the frictional force due to the friction between 55 and 57 and scraping. The washer 59 is formed of a resin member, and adjusts a frictional force generated between the washer 59 and a member facing each other by tightening the bolts 54 and 56, for example, a corresponding side plate of each bracket 53, 55, 57. To do.

For example, in the up-and-down swing mechanism 51, the left side plate 62, the washer 59 of the first bracket 53, the left side plate 72 of the second bracket 55, and the first side of the first bracket 53 are sequentially arranged from left to right in a front view. The right side plate 61 of the bracket 53, the washer 59, and the right side plate 71 of the second bracket 55 are lined up (see FIG. 6). In addition, the left and right swing mechanism 5
2, when viewed from the front, in order from top to bottom, the upper side plate 73 of the second bracket 55, the washer 59, the upper side plate 81 of the third bracket 57, the lower side plate 74 of the second bracket 55, The washer 59 and the lower side plate 82 of the third bracket 57 which is the base side are arranged (see FIG. 7).

With the arrangement of the side plates as described above, at the time of assembly,
The gap between the corresponding side plates can be widened, and the washer 59 can be easily sandwiched in this gap, so that the washer 59 can be easily assembled. For example, in the up-and-down swing mechanism 51, as shown in FIG. 9, one bolt 54 is attached to the washer 60,
The resin washer 59, the side plate 71 on the right side of the second bracket 55, and the resin washer 59 are passed through (FIG. 9A).
(Illustrated on the left side of). The other bolt 54 is attached to the washer 6
0, the resin washer 59, the left side plate 62 of the first bracket 53, and the resin washer 59 (FIG. 9).
(Shown on the right side of (a)). In the conventional structure, the both side plates of the other bracket are fitted between the both side plates of the one bracket, and the side plates face each other and only the thickness of the washer is enough to assemble the washer between the side plates. It was difficult to assemble because I had to insert a washer into a narrow gap and put a bolt through. On the other hand, in the present embodiment, it is sufficient to pass the washer 59 from the open end of the bolt 54, which is easy to assemble.

Next, the former bolt 54 is passed through the right side plate 61 of the first bracket 53, and the latter bolt 54 is passed through the left side plate 72 of the second bracket 55. Next, a washer 60, a plurality of disc springs 86, a washer 60, a torsion coil spring 87, a washer 60, and a nut 58 are passed through each bolt 54 from the head side, and the nut 58 is screwed in. It is desirable that the nut 58 prevent the nut 58 from returning to the tightening of the bolt 54. The torsion coil spring 87 is omitted in the left-right swing mechanism 52.

The structure in which the side plates are connected to each other by the bolts 54 and 56 and the nut 58 is substantially the same for both swinging mechanisms 51 and 52. Further, the connecting mechanism 28 has a reinforcing plate 88 that increases the bending rigidity of the display unit 11 by extending along the rear surface 31 of the display unit 11. The reinforcing plate 88 is formed integrally with the first bracket 53. The first bracket 53 includes the above-described connecting plate 63 that connects the pair of side plates 61 and 62 arranged side by side,
A pair of extending portions 64 extending from the connecting plate 63 and extending in a vertical direction orthogonal to the direction in which the pair of side plates 61 and 62 are arranged.
And a pair of bent bent portions 65 formed on the pair of extended portions 64, respectively. The bent portion 65 and the extended portion 64 form a reinforcing plate 88.

The extending portion 64 is in contact with and fixed to the rear surface 31 of the display portion 11. The extending portion 64, along with the vertical direction,
It also extends to both sides in the left-right direction. As a result, the display unit 1
1 is supported from the rear surface 31 to enhance bending rigidity with respect to vertical and horizontal swinging. The bent portion 65 includes the pair of extended portions 6
4 are arranged at the upper and lower end portions, have an L-shaped cross section, extend in the left-right direction, and reinforce the extending portion 64 against swinging in the left-right direction. Further, it is conceivable that the bent portion 65 for reinforcing the bending force that causes it to swing vertically may be formed so as to extend in the vertical direction.

As described above, the rigidity of the display portion 11 can be improved by the reinforcing plate 88, which contributes to suppressing the shake of the display portion 11 when the touch panel 15 is operated. Moreover,
The reinforcing plate 88 and the first bracket 53 can be integrally formed to simplify the structure. Further, the connecting mechanism 28 includes a holding mechanism for holding the display unit 11 with a predetermined holding force, a biasing mechanism for facilitating adjustment of the direction regardless of the weight of the display unit 11, and a swinging angle range. A stopper for regulating is provided. It should be noted that it is conceivable to use another known configuration as a configuration for these.

The holding mechanism has a plurality of the above-mentioned disc springs 86. Due to the elastic repulsive force of the disc spring 86, each bolt 5
The pair of side plates connected by 4, 56 are urged to urge each other, and a predetermined holding force is obtained by the frictional force generated between the side plates. Display unit 1 with operating force that exceeds holding force
The direction can be adjusted by rocking 1. Further, when the swing is stopped, the display unit 1 is held by the holding force in the state at that time.
1 is retained. This allows the user to touch the touch panel 1
The display unit 11 can be firmly supported while resisting the pushing force when operating the display unit 5, and the direction of the display unit 11 can be adjusted by a simple operation of directly holding and moving the display unit.

Further, as described above, the weight of the display unit 11 can be reduced, so that the component for resisting the gravity applied to the display unit 11 can be reduced in the holding force, and the holding force can be substantially retained. The ingredients for can be increased. As a result, for example, the holding force can be substantially increased and the display unit 11 can be reliably held without increasing the elastic repulsion force of the disc spring 86 and without increasing the operating force for swinging. . The biasing mechanism has the above-mentioned torsion coil spring 87 that biases the pair of brackets 53, 55 of the vertical swinging mechanism 51 around the first swinging axis C1. The spring 87 is arranged so as to surround the bolt 54, one end extending from the coil abuts on the connecting plate 63 of the first bracket 53, and the other end thereof contacts the connecting plate 75 of the second bracket 55. The display portion 11 is in contact with and urges the display portion 11 to swing upward while resisting the moment of swing due to the weight of the display portion 11. By the biasing mechanism, the operating force for adjusting the orientation of the display unit 11 can be reduced between upward and downward, and the operation can be facilitated.

The stopper of the vertical swing mechanism 51 is a bolt 8 screwed into the right side plate 61 of the first bracket 53.
9 and the second bracket 55 through which the bolt 89 is inserted.
And a peripheral edge portion 77 of an arc-shaped groove 76 formed on the side plate 71 on the right side of. The groove 76 is formed so as to correspond to a swing angle range of swinging up and down. The swing range is restricted by the bolt 89 coming into contact with the peripheral edge portion 77 at the end of the groove 76. Further, the bolt 89 and the female screw into which the bolt 89 is screwed can press the side plates 61 and 71 releasably, and the bolt 89 can be tightened to prevent swinging.

The stopper of the left-right swing mechanism 52 is a pair of inclined surfaces 8 at the front of the upper side plate 81 of the third bracket 57.
4 and the second bracket 55 that contacts the inclined surface 84.
And the connection plate 75. At the end of the swing range, the corresponding inclined surface 84 contacts the connecting plate 75 to regulate the swing. As the stand 12, for example, the base 1
7 and the column 16 may be swingable, or a plurality of columns 16 may be swingably connected to each other.

Further, as the thin display 14, instead of a liquid crystal display, a plasma display, an LED
Other known thin displays such as a display may be used. In addition, the touch panel 15 and the interface 1
A configuration in which at least one of the circuits for connecting external devices in 9 is omitted is also conceivable. Besides, various modifications can be made within the scope of the claims of the present invention.
