DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch panel type display provided in, for example, an outdoor terminal device of a gas station.

[0002]

2. Description of the Related Art Since such a display is used outdoors,
Dirt and dirt adhere between the touch panel and the liquid crystal display, which is a major obstacle in use. On the other hand, if the touch panel and the liquid crystal display are completely dustproof, the internal temperature rises due to dew condensation or strong direct sunlight and the display contrast deteriorates. For this reason, the performance must be ensured by increasing the ventilation, so that dust and dirt tend to adhere.

[0003] When the touch panel is used for a long time,
The protective film covering the surface of the touch panel is stretched, abraded, or glossy only at the part of the key that is constantly pressed, and the display becomes unclear.

[0004]

Therefore, if dust or dirt adheres between the touch panel and the liquid crystal display, it is necessary to clean the back surface of the touch panel and the surface of the liquid crystal display. However, the cleaning work is very troublesome due to the structure that cannot be cleaned unless disassembled.

When the display becomes unclear due to extension of the protective film, it is necessary to replace the display with a new one. However, with the conventional structure, it is troublesome to remove and replacement is difficult.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a touch panel display in which the back surface of the touch panel and the surface of the liquid crystal display can be easily cleaned, and a protective film can be attached and detached.

[0007]

According to the present invention, the upper edge is pivotally connected to the upper edge of the case opening, and the lower edge is detachably attached to the lower edge of the opening by the first stopper. A frame-shaped first frame that is fixed and selectively locked substantially horizontally to the case by a stopper arm, an upper edge portion is pivotally connected to an upper edge portion of the first frame, and a lower edge portion is a second edge portion. A frame-shaped second frame detachably fastened to a lower edge portion of the first frame by a stopper, a touch panel attached to an opening of the first frame, and a touch panel attached to an opening of the second frame. The touch panel of the first frame is provided with a liquid crystal display which is mounted facing the gap with a gap.

Further, according to the present invention, the first and the second
The stopper is a one-touch type including a ball portion and a concave portion.

Further, according to the present invention, a removable protective film is provided.

[0010]

In the touch panel display constructed as described above, when cleaning the touch panel and the liquid crystal display, the first stopper at the lower edge of the first frame is removed and pulled up, and the stopper arm is lifted. Holds the first frame substantially horizontally. Next, the second stopper is removed from the lower edge of the second frame, and the second frame is suspended. In this state, the rear surface of the touch panel facing downward and the front surface of the liquid crystal display panel whose front surface is exposed are cleaned.

When the protective film is to be removed, the film is bent, the engaging projection is removed from the locking projection of the first frame, and the film is removed. After the cleaning is completed or after the film is attached, the above operation may be performed in reverse.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a card reader 4 and a printer 5 are respectively provided at a lower portion of a case 3 supported by a post 2 of an outdoor terminal device, which is generally denoted by reference numeral 1, and a whole is denoted by reference numeral 10 at an upper portion. The touch panel display shown is provided.

In FIG. 2, on the upper part of the case 3,
A rectangular opening recess 3a is formed. An upper edge of the rectangular frame-shaped first frame 11 is pivotally connected to an upper edge of the opening recess 3a via a pair of hinges 12, and a lower edge of the first frame 11 is It is detachably fastened to the lower edge of the opening recess 3a by a one-touch first stopper 13.

A touch panel 14 is provided behind the opening 11 a of the first frame 11, and the surface of the touch panel 14 is covered with a protective film 15. As shown in FIG. 3, the film 15 is provided with engaging projections 15a projecting from upper and lower edges, respectively, and a pair of locking recesses 11b formed on upper and lower edges of the opening 11a of the frame 11, respectively. And is detachably attached to the opening 11a. On both sides of the first frame 11, one end of a pair of stopper arms 16 is pivotally connected by pins 16b, and the other end of the stopper arm is selectively locked to a stopper 3b protruding from the case 3. The engaging recess 16a to be formed is formed.

At the rear upper end of the first frame 11,
The upper edge of the rectangular frame-shaped second frame 17 is pivotally connected by a pair of hinges 18, and the lower edge of the second frame 17 is firstly moved by a pair of left and right one-touch type second stoppers 19.
It is detachably fixed to the frame 11. The opening 17a of the second frame 17 has a touch panel 14
The liquid crystal display 20 is mounted with a gap C provided therebetween, and the touch panel 14 and the liquid crystal display 20
Are connected to the control device 21 provided on the upper part of the device.

Next, the operation will be described.

The back surface of the touch panel 14 and the liquid crystal display 20
First, as shown in FIG. 4, when cleaning the surface of
After pulling the lower edge 11c of the frame 11 to remove the ball portion 13a of the first stopper 13 from the concave portion 13b, it is pulled up to lock the engaging concave portion 16a of the stopper arm 16 with the stopper 3b. 11 is held in a substantially horizontal position.

Next, as shown in FIG. 5, the knob 19c on the ball portion 19a side of the second stopper 19 is pulled out of the concave portion 19b, and the second frame 17 is hung down. Therefore, in this state, the back surface of the touch panel 14 and the front surface of the liquid crystal display 20 are cleaned.

After the cleaning is completed, the second frame 17 is pulled up to stop the second stopper 19 and return to the state shown in FIG. 4, and the stopper arm 16 is turned slightly upward to engage the engaging recess 16a.
Is removed from the stopper 3b, the first frame 11 is lowered, and the concave portion 13a is fixed to the ball portion 13b.

When the film 15 is to be replaced, the film 15 is bent forward as shown in FIG.
a is removed from the locking recess 11b of the first frame 11, and the film 15 is removed from the first frame 11. Therefore, the new film 15 is similarly curved and the engaging projection 15a is locked in the locking recess 11b, and the film 15 is mounted in the opening 11a.

[0022]

According to the present invention, as described above, the back surface of the touch panel and the front surface of the liquid crystal display can be easily cleaned.

Further, the protection filter can be easily attached and detached.
