[Technical field to which the invention belongs]

 The present invention relates to a work-assisting display cover sheet placed on a pen input unit in order to prevent an operation error of a pen input unit (work area) due to handwritten characters of a PDA (Personal Digital Assistance “portable information device”). .

[0002]

2. Description of the Related Art In a portable information device having a pen input unit using handwritten characters such as a PDA, a method of inputting information from a screen of a display device (menu) consisting of characters and pictures on the screen. Is displayed, and a handwriting character input unit using a stylus pen is placed on the screen, and the operator selects a desired menu or performs character input, so that information is displayed on the screen via the control unit inside the device main body. Is displayed.

[0005] However, when a menu button is arranged near an input unit for handwritten characters in these devices, the menu button may be erroneously selected with a stylus pen at the time of character input. As disclosed in JP-A-10-31431 and JP-A-11-181370, a cover sheet for a display which is disposed on a screen surface for the purpose of preventing a display from being stained or static electricity or removing bacteria is known. It was not something.

Further, in the case of a PDA, it is necessary to reduce the size of the entire device. For this reason, a menu button must be arranged near the character input unit, and the darkness in a warehouse or the like due to the convenience of carrying. There are many inputs at the place, and the problem caused by the erroneous operation is a problem.

[0005]

[Problems to be solved by the invention]

 The present invention has been made in view of the above, and is intended to prevent a user from accidentally selecting a menu button arranged near a character input unit when inputting handwritten characters using a PDA. It aims to provide display cover sheets.

[0006]

[Means for solving the invention]

 In order to achieve the above object, the present invention provides a main body made of a transparent resin sheet, a frame having a convex surface provided around a pen input area by a stylus pen, and an upper surface of the main body outside the pen input area. And a button portion having a convex surface provided at a desired position. According to the display cover sheet of the present invention, by applying the present invention to a pen input unit using a stylus pen of a pen input type portable information device such as a PDA, a menu button near the pen input unit can be selected by mistake. Can be prevented.

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. FIG. 1 is an overall view showing one embodiment of the present invention. The main body 1 is made of a transparent resin and is made of a sheet-like material (such as transparent polyvinyl chloride) so that the display 7 can be seen through when the display 1 is placed on the display 7 of the PDA 6. The frame 3 is provided on the upper surface of the main body 1 so as to surround a pen input area 2 for inputting handwritten characters using a stylus pen, and deforms the main body 1 into a convex shape by pressure, heat or the like. The input area 2 and other areas of the main body 1 are separated. The button portion 5 is provided on the upper surface of the main body 1 outside the pen input area 2 so as to be convexly deformed from the upper surface of the main body 1 like the frame 3.

FIG. 2 shows an example of a PDA using the display cover sheet according to the present invention. As the PDA device, a product name “WorkPad” of IBM Japan, a product name “Palm” of 3Com, etc. Are sold. A display 7 is provided on the main body of the PDA 6, and the display 7 is divided into a display area 8 for input information and a work area 9 for inputting handwritten characters and the like. The work area 9 is divided into an alphabet character input section 10a and a number input section 10b when a product name "Palm OS", which is an OS of 3Com, is used to reduce erroneous recognition of handwritten characters. Has become. Various menu buttons 11 are arranged near the character input units 10a and 10b.

The sheet size of the main body 1 is the same size as the work area 9 of the PDA 6, and the frame 3 has a frame line 10 c indicating the area of the character input units 10 a and 10 b when the main body 1 is arranged in the work area 9. They are arranged to overlap. The button section 5 is also arranged so as to overlap the menu button 11. The convex portion 4 provided in the pen input area 2 is a mark indicating a boundary between the character input portions 10a and 10b, and is a protrusion provided on the upper surface of the main body 1 like the frame 3 and the button portion 5. .

The main body 1 can be configured to have a size that covers not only the work area 9 of the PDA 6 but also the entire display 7. Although the size of the work area 9 and the arrangement position and size of the menu button 11 are different for each model of each maker, it can be dealt with by manufacturing the size and the position of each model.

Next, a method of using the display cover sheet according to the present invention will be described. The main body 1 is arranged so as to overlap the work area 9 of the PDA 6. A detachable adhesive layer may be provided on the back surface of the main body 1 on the surface of the work area 9 to prevent the main body 1 from shifting during work. It is not an essential requirement for the invention. Further, since the main body 1 is formed of a transparent resin sheet, even if the main body 1 is arranged on the upper surface of the work area 9, the handwritten characters and the menu buttons 11 displayed on the work area 9 can be seen through. . When inputting handwritten characters into the character input sections 10a and 10b, the stylus pen is provided with the stylus pen since the frame 3 provided around the pen input area 2 projects upward from the upper surface of the main body 1. The user does not move beyond 10a and 10b and does not select the menu button 11 by mistake.

When operating the menu button 11, the menu button 11 in the work area 9 is selected by pushing the convex bulge of the button section 5 from above. In this case, the normal button operation simply touches the menu button displayed in the work area 9, and it is difficult to determine whether the selection is accurate or not. It is possible to get a feeling.

By providing roughness on the surface of the main body 1 with minute irregularities that do not impair the see-through to the display 7, the pen input unit 2 causes the pen input unit 2 to slip too much when inputting handwritten characters with a stylus pen. It is possible to prevent writing mistakes caused by writing, and to feel like actually writing characters using paper and a pen.

Although the frame 3 provided on the main body 1 is illustrated so as to surround three sides of the pen input area 2, it may be provided so as to surround four sides of the pen input area 2. Further, the frame 3 and the button portion 5 are provided by deforming the main body 1 in a convex shape, but it may be configured such that transparent silk printing for Braille or a thick resin material is attached. In this case, the ink or resin material is more preferably a material having elasticity. Furthermore, although the projections 4 provided in the pen input area 2 are shown as small projections, they may be provided over the entire boundary of the character input sections 10a and 10b.

[Effect of the invention]

 As described above, according to the present invention, by disposing the display cover sheet in the work area (handwritten character input unit) of the PDA, even in a relatively dark place such as a moving place or a warehouse, the display cover sheet can be used. It is possible to prevent a menu button provided near the input unit from being selected by mistake. Also, when selecting a menu button displayed on the display, it is possible to obtain the feeling of operating a mechanical button. Further, by providing minute irregularities on the surface of the main body, it is possible to obtain a feeling of writing characters using a paper and a pen even when inputting characters on a display with a stylus pen.
