2. Description of the Related Art In a conventional pen input electronic device, a surface plate serving as a pen input surface is provided outside a liquid crystal panel (hereinafter referred to as an LCD panel), but as shown in FIG. The surface plate 1 has a pressure sensitive sheet tablet 3 attached to the upper surface of the glass plate 2, or the surface plate 1 has the lower surface of the glass plate 2 coated or laminated with an electromagnetic tablet 4 as shown in FIG. 3B. It adopts the one.

Further, in the mounting structure, as shown in FIGS. 4 (a) and 4 (b), the surface plate 1 is attached under the housing window frame 5. For this reason, the upper surface 1a of the surface plate 1 is located at a position further down from the window frame upper surface 6 of the housing.

[0004]

In the case of the surface plate shown in FIG. 3 (a), the upper side of the surface plate 1 is the pressure-sensitive sheet tablet 3 for position detection, and the upper surface is not subjected to the antiglare process. Is hard to see. Alternatively, even if the antiglare treatment is applied, it is general that there are few kinds and the degree thereof is not so good.

In the case of the surface plate shown in FIG. 3 (b), the upper surface is the glass plate 2 which is not anti-glare or weakly processed, and the pen 8 is slippery and difficult to write.

Both FIG. 3 (a) and FIG. 3 (b)
Since the glass plate 2 is used as the base material, the touch feeling when writing with the pen 8 is stiff, and tired when writing for a long time. Further, the glass plate 2 has a risk of being broken and scattered.

In the case of the structure shown in FIGS. 4A and 4B, the writing pressure and the load of the arm directly act on the functional members such as the LCD panel 7. Further, the front panel 1 bends and the LCD panel 7
A force may be applied to the central part of the LCD, causing damage such as uneven color due to the unevenness of the spacer inside the LCD. Further, there is a step between the upper surface 1a of the surface plate 1 and the window frame upper surface 6 of the housing, and when it reaches the end at the time of pen input, the hand holding the pen 8 rides on this step and it becomes difficult to write.

Therefore, the present invention eliminates the above-mentioned drawbacks,
It is an object of the present invention to provide a pen input electronic device which has excellent operability and durability and can perform pen input without a sense of discomfort.

[0009]

The surface that comes into contact with the pen has been subjected to writing quality adjustment processing.

Further, each of the above pen input electronic devices is characterized in that a gap is provided between the surface plate and the LCD panel, and further, the surface of the surface plate on the side contacting the pen and the casing window frame. The feature is that there is no step between them.

[0012]

In the pen input electronic device of the present invention, since the surface plate is made of the elastic synthetic resin, the feel when writing with a pen is soft, and it is harder to break than glass, and if it breaks. However, the debris is not very dangerous and does not scatter. Furthermore, since it is a resin plate, antiglare treatment can be easily performed at low cost, and there are many types of selection.

(Interference fringes due to external light) are prevented from occurring, and the display on the LCD panel screen is easy to see. In addition, since the writing touch adjusting process is performed on the surface of the surface plate or the pressure-sensitive sheet tablet that is in contact with the pen, the pen is less likely to slip and the writing touch is improved.

Further, since a gap is provided between the surface plate and the upper surface of the LCD panel, the feeling when writing with a pen becomes softer, and writing pressure and arm load are not applied to the LCD panel. Even if it bends, it will be difficult to contact the LCD panel. Further, the generation of Newton's rings (interference fringes) due to the adsorption of water is prevented.

By eliminating the step between the surface of the surface plate that is in contact with the pen and the housing window frame, when entering characters etc. with the pen, when the end reaches the end, the hand will step up. It will not be difficult to write.
