2. Description of the Related Art FIG. 7 is a side view showing an example of a conventional panel type display device in use. The panel-type display device 1 includes a liquid crystal display 2 with an input function and a slide stand 3. The liquid crystal display 2 with an input function is provided with wheels 1a on the bottom surface in an upright state, and has a hinge means 1b and the liquid crystal display 2 with an input function on the back side at a predetermined tilt angle at the top plate 5A of the desk 5. It has a leg 1d for supporting it above.

The slide stand 3 includes a fixing jig 4 that can be screwed to the top plate 5A of the desk 5, a hinge 1c pivotally supported by the fixing jig 4, a hinge 1c, and a hinge 1b of the liquid crystal display 2 with an input function. And an arm 1e connecting the two. In a state where the liquid crystal display with input function 2 is supported on the top plate 5A of the desk 5 by the leg 1d, the height of the arm 1e on the hinge 1b side is set to be slightly higher in advance than the height position on the hinge 1c side. Have been.

FIG. 8 shows the panel type display device 1 described above.
FIG. 4 is a top view showing a use state of the liquid crystal display. A liquid crystal display with an input function 2 is connected to a personal computer (not shown) and is used as a display device. Also used as a device. Also,
In use, it is configured in advance by the legs 1d on the back so as to be installed on the top plate 5A at an inclination angle that is generally easy for the operator to input.

FIG. 9 shows this panel type display device 1.
It is a side view which shows the storage state of. To put the panel-type display device 1 in the stowed state, when the operator pushes the liquid crystal display with input function 2 toward the back of the desk 5 in the use state of FIG. To roll
The liquid crystal display with input function 2 and the arm 1e move to the back of the desk 5 while standing up, and the panel-type display device 1 enters the storage state shown in FIG. In the stowed state, the liquid crystal display with input function 2 is in a slightly forwardly inclined posture, and the wheels 1 a are stopped by the fixing jig 4.
It is a kind of locked state due to gravity. The reason why the hinge 1b side of the arm 1e is located slightly higher than the hinge 1c side as described above is to allow the liquid crystal display with input function 2 and the arm 1e to rise up smoothly when stored.

FIG. 10 is a top view showing the stored state of the panel type display device 1. The liquid crystal display with input function 2 is standing on the back side of the desk 5, and the top plate 5A is closed. Since there is no operator, the operator can perform another operation on the top 5A.

In the panel-type display device 1 having such a configuration, for example, the liquid crystal display 2 having an input function of about 5.6 kg is always supported on the top plate 5A of the desk 5 by the wheels 1a. It was good with a lightweight structure. In order to change from the storage state to the use state, the desk 5
The liquid crystal display 2 with an input function standing in the rear side of the vehicle can be easily pulled out to the front side while rolling the wheel 1a. In order to change from the use state to the storage state, the input function-equipped liquid crystal display 2 can be easily pushed into the back of the desk 5 while rolling the wheel 1a, and the input function-equipped liquid crystal display 2 can be stood up. Let it. Thus, the panel-type display device 1
The posture of the use state and the storage state was changed.

[0008]

By the way, in the panel type display device 1 having such a configuration, the liquid crystal display 2 with an input function is provided on the back surface of the top plate 5 of the desk 5 at a predetermined inclination angle.
A leg 1d supported on A was provided, and the angle of inclination was set to 15 °, which was excellent in input workability. However, when the panel-type display device 1 is changed from the stored state to the used state, if the inclination angle is gradually reduced, the liquid crystal display 2 with the input function will not move due to its own weight when the inclination angle becomes about 15 °. There was a risk of falling sharply onto the plate 5A. Further, it is difficult to set the screen operation angle to an angle other than the angle determined by the leg 1d, and there is a problem in workability at the time of input.

Accordingly, an object of the present invention is to eliminate the danger of a sudden drop of a liquid crystal display with an input function when a panel type display device is changed from a stored state to a used state, and to set the screen operation angle to an arbitrary angle. It is an object of the present invention to provide a panel type display device which can be used.
