Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device having a touch panel on the front of a display screen.
In particular, the present invention relates to a display device capable of holding an angle of a display screen at an arbitrary position when inputting on the display screen.

[0002]

2. Description of the Related Art In a display device having a touch panel on the front of a display screen, various programs are selected by touching a specific position on the touch panel based on the display contents of the screen.

[0003] It is necessary to prevent the display screen from being difficult to see due to the prevention of reflection of illumination and the operation posture of the operator. Therefore, the display screen can be set to an arbitrary angle. In order to set the display screen at an arbitrary angle, it is generally known to employ a tilt mechanism in which the display unit is rotatable with a predetermined pressing force and is attached to the base unit.

This tilt mechanism sets the display unit to an arbitrary angle by rotating a shaft. Then, the spring force for urging the shaft is configured so that the spring force is constant with respect to the amount of displacement of rotation of the shaft. Therefore, in the angle adjustment of the display unit, a predetermined pressing force can be obtained constantly. When the pressing force is exceeded, the display unit rotates.

[0005] The pressing force of the display screen at the time of input by the touch operation on the touch panel exceeds the spring force of the tilt mechanism depending on the place where the display screen is pressed. For this reason, the touch operation cannot be performed because the angle of the display unit moves. Therefore, it is necessary to hold the position of the display unit whose angle has been adjusted.

FIG. 5 shows an external view of the prior art. In the figure, a base unit 101 and a display unit 102 are tilt mechanisms 103 having the above-described mechanism.
Have been moored through. At the time of input using the touch panel, a support bar 104 is used to hold the position of the display unit whose angle has been adjusted. One end of the support bar 104 is rotatably attached to the display unit 102 by a rotation member 105. The other end of the support rod 104 is provided with a plurality of recesses 107 at predetermined intervals.
It is engaged with one locking portion 106.

After the angle of the display unit 102 is adjusted to a desired position by the tilt mechanism 103, the support bar 104 is locked in a predetermined recess 107 so as to be engaged with the locking portion 106. Thus, even if the display screen is pressed with a pressing force exceeding the spring force of the tilt mechanism 103, the support rod 10 is pressed.
4, the position of the display unit 102 does not change.

In this display device, the locking unit 106 having a large space is required in the base unit 101, and the display device has been increased in size. Further, the support rod 104
In the above operation, the operator must operate the support bar 104 one by one when engaging with or releasing from the locking portion 106, and this type of operation is troublesome.

[0009]

As described above, the conventional display device has the following problems.

1) The display device has been increased in size.

2) The operation for maintaining the position of the display screen whose angle has been adjusted has been troublesome.
