(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows the appearance of a POS terminal according to this embodiment. This POS terminal comprises a terminal main body 1 and a display device 2 rotatably attached to the terminal main body 1 via a hinge. As shown in FIG. 2, the display device 2 includes a liquid crystal display device 4 in a frame 3, a touch panel 5 arranged on the liquid crystal display device 4, and a transparent protective sheet 6 attached thereon. The frame 3 is composed of two parts, a front frame 3A and a rear panel 3B.
Has a rectangular opening 7 that is slightly smaller than the touch panel 5. The protective sheet 6 has its both sides and the upper side attached to the gap 8 between the peripheral edge of the opening 7 and the touch panel 6,
The folding side 6a formed there is exposed to the outside on the lower side.

The protective sheet 6 is formed of a thin polyester film, and as shown in FIG. 3, a bent piece 6a bent forward at an angle θ is formed on the entire lower side. Slits 6b and 6c are formed obliquely inward on both sides of the bent piece 6a, that is, at the corners of the lower side and the both sides. The entrances and bottoms of the slits 6b and 6c are formed in a round shape. Further, shallow and wide notches 6d and 6e are formed on the upper side and the side of the right corner at positions slightly apart from the tips of the corners. Further, the surface of the protective sheet 6 is hard-coated to form an antireflection coating.

In FIG . 4, the protective sheet 6 is mounted on the frame 3.
It shows the procedure when wearing. First, in STEP 1, protect
The lower corner of the left side of the seat 6 is provided with the frame 3 and the touch panel 5.
Insert it in the gap 8 and then in STEP 2, the upper corner of the left side
Insert into the gap 8. Due to this operation, a part of the upper side has a gap 8
As it is inserted into the
Insert it in the right direction of the, and in STEP 3, the upper right of the protective sheet 6
Move the corner slightly inward and then open the corner and the upper right side.
Insert in space 8. At this time, the notch 6 provided at the upper right corner
d and 6e prevent the upper side from coming off the gap 8. So
Then, in STEP 4, insert the lower corner of the right side into the gap 8.
Protects the folded-back piece 6a on the lower side outside
The seat 6 can be attached to the frame 3. This and
Since there are slits 6b and 6c provided at both corners of the lower side,
No stress is applied to the folded-back piece 6a, and the protection piece is protected.
Prevents cracks from entering the door 6. Remove the protection sheet 6
At the time, as shown in FIG. 5, put the protective sheet 6 on the thumb and the other 4
You can easily slide it out by sliding it inward as if you grab it with your fingers.
You can

As described above, according to the present embodiment, since the protective sheet 6 is attached to the frame 3 to cover the top of the touch panel 5, dirt can be prevented from adhering to the touch panel and the touch panel can be a pen or pen. Even if the touch panel is pressed with a pencil, the touch panel is not damaged, and even if the touch panel is damaged, it is possible to prevent the fragments from scattering. Further, since the folding piece 6a is provided on the lower side of the protective sheet 6, dust can be prevented from collecting on the lower side of the frame 3, and even if juice or cola is accidentally spilled, it can be prevented from entering the frame. Can be prevented. Further, since the antireflection coating is formed on the surface of the protective sheet 6, it is possible to prevent the reflection of the fluorescent lamp indoors and the reflection of sunlight outdoors.

[0019]

According to the present invention, as is apparent from the above-described embodiment, a folding piece is provided on the lower side in the gap between the periphery of the display screen of the display device and the frame surrounding the display screen.
Slits are formed diagonally inward at the corners of the sides
At the same time, at the corner between the upper side and one side, the corner tip
Shallow cutouts on the upper and side edges, slightly away from
Having mounted the protective sheet to form a can, together with the attachment and detachment is easy of the protective sheet, it is possible to protect the display screen, even spilled drinks or the like can be prevented them from entering into the apparatus, further It is easy to put on and take off the protective sheet
Have an effect.
