The foot bracket 7 is designed so that when it is attached to the display device 1, its appearance is not impaired. The foot 8 is connected to the supports 8a, 8
It has a plurality of gears 8b formed at predetermined angular intervals on an arc centered at a, and after being attached to the display device 1, protrudes from the bottom portion 1a of the display device 1 according to a predetermined angle setting. The amount of protrusion is variable.

By assembling the above-mentioned foot bracket 7, foot 8 and lock lever 9 as shown in FIG. 2, the angle adjustment mechanism 6 shown in FIG. 3 can be obtained.

That is, the foot 8 becomes rotatable by engaging its supports 8a, 8a with the fulcrums 7a, 7a of the foot bracket 7. In this engaged state shown in FIGS. 2 and 3, the supports 8a, 8a of the foot 8 easily move in the direction of the arrow in FIG. 4 from the fulcrums 7a, 7a of the foot bracket 7, as shown in FIG. 4A. However, after the angle adjustment mechanism 6 shown in FIG. 3 is attached to the rear bottom part 1a1 of the display device 1, the foot bracket 7 will fall off as shown in FIG. 4B.
Supports 8a, 8a of the foot 8 from the fulcrums 7a, 7a of
will not fall off, and therefore the foot 8
is capable of circular rotation around its fulcrums 7a, 7a. By regulating this circular rotation in stages, the bottom portion 1a of the display device 1 is
By being able to set the amount of extension of the foot 8 (that is, setting the angle), the display device 1
Rear bottom part 1 of display device 1 from the installation surface of
The height of a1 can be arbitrarily varied, and the screen 1b can be directed to an arbitrary position. Foot bracket 7
The lock lever 9 is inserted into the sliding parts 7b, 7b in advance, and the foot 8 is inserted into the stopper part 9c.
The angle adjustment mechanism 6 is completed by inserting the gear 8b and storing the spring 10 in the spring storage portion 9b of the foot bracket 7 via the spring receiving portion 7d.

5A to 5C are diagrams showing the mutual positional relationship of the foot bracket 7, foot 8, and lock lever 9 that constitute the angle adjustment mechanism 6, respectively. When the lock is released, FIG. 5C shows the respective mutual states when the lock is locked, and FIGS.
FIG. 6 is a diagram showing the coupling relationship between the foot 8 and the lock lever 9, and FIG.
C shows the coupling relationship between the foot 8 and the lock lever 9 from the time of unlocking to the time of locking, and D of the same figure shows the coupling relationship between the foot 8 and the lock lever 9 at the time of locking.

When assembling the angle adjustment mechanism 6, as shown in FIGS. 5A and 5A', if the spring 10 is not yet stored in the spring storage portion 7d of the foot bracket 7, the lock portion 7c of the foot bracket 7 and the lock lever 9 Since the openings of the stopper portions 9c can be aligned with each other, an opening large enough to allow the falling-off prevention claw 8c to be inserted is formed here. Arrow C in FIG. 5 indicates the direction in which the lock lever 9 is operated.

After that, when the lock is released, the elastic force F of the spring 10 stored in the spring storage portion 7d of the foot bracket 7 is increased as shown in FIGS. 5B and B', respectively.
When the lock lever 9 is manually operated in the direction of arrow C against this, the stopper portion 9c of the lock lever 9 is caught on the fall-off prevention claw 8c of the foot, so that the foot 7 is moved within the range of the base portion 8d between each gear 8b, 8b. (as shown in Figure 6A). Here, the spring 10, which is elastically stored between the spring receiving part 7d of the foot bracket 7 and the receiving part 9d of the spring storage part 9b, pushes the lock lever 9 inserted into the foot bracket 7 with a resilient force F( (direction of arrow F shown in Figure B)
It acts by pressing from the inside to the outside.

After this, when lock lever 9 is released, spring 1
The lock lever 9 moves with an elastic force F of 0, and the stopper portion 9c of the lock lever 9 is fitted and fixed to the gear 8b, as shown in FIGS. 5C and C' and FIG. 6D, respectively. The lock state is complete. During the transition from unlocking to locking, sloped portions 8b1 and 9c1 are provided on each gear 8b of the foot 8 and the stopper portion 9c of the lock lever 9, respectively (as shown in FIG. 6B), so that locking can be performed smoothly. (Illustrated in the figure is a hooked state and a state in which the foot 7 is moving due to gravity as shown in Figure C).

After configuring the angle adjustment mechanism 6 in this way, the mounting holes 7e, 7e, 7 of the foot bracket 7 are
The display device 5 of the present invention can be constructed by passing screws (not shown) through e and 7e, respectively, and screwing them into the respective mounting recesses provided in the rear bottom portion 1a1 of the display device 1.
Since the height of this angle adjustment mechanism 6 is lower than the combined height of the conventional stand 2 and slider 3 described above, manual operation of the lock lever 9 and rear bottom portion 1a1 of the display device 1 can be easily adjusted. Even if the orientation of the screen 1b is set to an arbitrary position within a limited height space by lifting it from the installation surface of the counter 4, the upper surface thereof will not come into contact with the lower surface of the counter 4.

(Effect of the invention) As mentioned above, the display device according to the present invention can be directly attached and fixed to the bottom of the display device 1, so its height can be lowered compared to the conventional display device fixed to a slider. Therefore, even when installed in a space, the screen orientation can be set to any desired position.
