Description

DETAILED DESCRIPTION OF THE INVENTION A. Industrial Application Field The present invention relates to a coordinate data input device, and is suitable for application to an information processing device that processes desired information based on coordinate data input from a tablet, for example. It is.

B. Summary of the Invention The present invention, in a coordinate data input device, prevents the loss of coordinate data by supporting the tablet with a housing so that an area smaller than the dynamic input area and larger than the effective display area of the display screen is open. It can be prevented.

C. Prior Art Conventionally, this type of information processing device has been proposed to be able to manage multiple types of personal information, such as a notebook, address book, telephone number book, schedule sheet, etc. (Patent application No. 1-31619, Patent application No. 2-84318
issue).

In such an information processing device, a tablet is placed on a liquid crystal panel, and the display screen of the liquid crystal panel is switched based on coordinate data input via the tablet, thereby visually confirming input results. It is possible to manage desired personal information.

That is, as shown in FIG. 6, for example, a schedule is displayed on the display screen H in response to the user's selection operation, and icons IA, IB, . . . are displayed at the top and right ends of the display screen H.
... is displayed.

This allows the user to use the necessary icons IA, I
After lowering the pen to B, ......, move the pen to a predetermined position on the display screen to move the window W corresponding to the icon IA, IB, ...... to the corresponding movement position. According to the display within the window W, personal information such as schedules can be managed.

D Problems to be solved by the invention As shown in Figure 7, a tablet is displayed on the display screen.
A coordinate input device configured to input coordinate data by arranging a tablet T includes an effective input area AR, . . . of a tablet T in which coordinate data can be input by operating a pen, and a display panel forming a display screen. It is assembled so that the effective display area AR of P coincides with the effective display area AR.

Furthermore, at this time, the opening in the housing is the effective input area A R
It is formed so as not to cover IN and the effective display area AR.

However, as shown in Fig. 8, in this type of assembly work, it is difficult to assemble the effective input area A RI N and the effective display area A RM due to assembly accuracy, and in this case, the effective input area A RI N and the effective display area A RM are difficult to assemble. Input area ARI
It is inevitable that an area A RI NN of N and an area ARMN of only effective display area AR occur.

For this reason, for example, part of the icon is in the effective display area AR,
If the area is displayed in such a way that it spans the area A RNN, the coordinate data will be missed in the area A RNN, and even if the pen is down on the icon,
It becomes impossible to specify the window of the icon.

Similarly, as shown in FIG. 9, in a pressure-sensitive tablet T, when the pen is moved across the area AR□, which is only the effective display area ARH, the pen crosses the boundary between the effective input area A Rr s and the area A RNN. It is determined that the pen is up and down at points P+ and Pt, and the coordinate data ends up being missed in the area ARMN.

The present invention has been made in consideration of the above points, and it is an object of the present invention to propose a coordinate data input device that can prevent coordinate data from being missed.

E! Means for Solving Problem II In order to solve this problem, in the present invention, a predetermined movable piece 6 is moved on the tablet 32 arranged on the display screen H.
In the coordinate data input device 1 , which sequentially inputs coordinate data according to the position of the movable piece 6 based on the output signal of the tablet 32 , the effective input of the tablet that operates the movable piece 6 and inputs the coordinate data The tablet 32 is placed in the housing A so that the area AR, , is set larger than the effective display area AR of the display screen H, and an area smaller than the effective input area AR, , and larger than the effective display area ARH is opened.
I support it.

The effective input area AR,, of the F action tablet 32 is displayed on the display screen H.
If the tablet 32 is supported by the housing A so that the effective display area A is set larger than the effective input area ARIN, and the effective display area AR is smaller than the effective input area ARIN and larger than the effective display area AR, it is possible to prevent coordinate data from being missed. I can do it.

(Gl-2) Tablet and display panel Figures 1 and 4
As shown in the figure, in this embodiment, the tablet 32
is supported by a housing A with a protective layer 40 made of a transparent sheet material disposed on the upper surface, and a liquid crystal display panel 5 is disposed on the lower surface.

Further, at this time, in the tablet 32, the effective input area A R+N is formed to be larger than the opening KK of the housing A, whereas in the liquid crystal display panel 5, the effective display area A RM is formed to be smaller than the opening KK. It is formed as follows.

Therefore, as in the past, area A of only the effective display area ARM
The occurrence of R□ can be effectively avoided, and accordingly, the failure to capture coordinate data can be effectively avoided.

On the other hand, the central processing unit 24 detects the coordinate data of the pen 6 by importing the coordinate data from the tablet interface circuit 31, corrects the coordinate data, and forms a display image.

That is, as shown in FIG.
2 and the display panel 5, when the user tries to move the pen 6 beyond the opening KK, the pen 6 gets caught on the opening KK and the level difference in the protective layer 400, and a trajectory along the opening KK occurs in that part. It is formed.

As a result, in the trajectory detected via the tablet interface circuit 31, after bending along the opening KK from the point P where the pen is down at the point P2, the point P,
The pen-up point P6 is detected from the pen-up point P6.

Thereby, even if the user attempts to move the pen 6 beyond the effective input area A Rr s, it is possible to effectively avoid missing coordinate data.

However, in the trajectory along the aperture KK of the relevant part, by being located outside the effective display area AR,
It becomes difficult to display the trajectory.

For this reason, the central processing unit 24 outputs the point P at which the pen is down.
After displaying the trajectory from 0 to pen 6,
The trajectory is displayed so that the point P where the trajectory crosses the boundary of the effective display area ARM and P are connected by a straight line.

Furthermore, point P, and thereafter, point P- where the pen is raised
The trajectory is displayed along the trajectory of the pen 6 up to the point where the trajectory of the pen 6 is displayed, thereby preventing the coordinate data from being missed.

(Gl-3) Operation of the embodiment In the above configuration, the information processing device t! 1, when the key switches 4a to 4d and lla to lid are turned on, the operation mode is switched and desired personal information is displayed on the display panel 5.

In this state, by moving the pen 6 down to a predetermined icon and moving it to the page data display area AR□, a window W is displayed at the moved position.

Further, by moving the pen 6 down to the displayed window W and then moving the pen 6, the display position of the window W can be moved to the movement position of the pen 6.

At this time, when the user crosses the effective input area AR,, the pen 6
When an attempt is made to move the pen 6, the pen 6 gets caught on the opening KK and the step of the protective layer 40, and a trajectory along the opening KK is formed at this portion.

As a result, the pen 6 that exceeds the effective input area A RI N
movement of the coordinate data can be prevented, and loss of coordinate data can be effectively avoided.

Furthermore, based on the captured coordinate data, for the movement of the pen 6 beyond the effective display area ARM, a trajectory is displayed along the boundaries of the effective display area ARN and the effective input area AR, l, and the coordinates are thereby The trajectory of the pen 6 can be displayed while preventing data from being missed.

(Gl-4) Effects of Example According to the above configuration, the effective input area A of the tablet 32
By setting the aperture KK of the housing A small for P I H, the pen 6 that exceeds the effective input area AR+
movement of the coordinate data can be prevented, and loss of coordinate data can be effectively avoided.
