Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a tablet device, and in particular, to a tablet device that provides positional information corresponding to a standard menu paper without being affected by the size and arrangement of menu paper that can be placed on a tablet. The present invention relates to an obtainable tablet device.

(El) Background of Technology CAD and CAM are technologies that rely on computers in the design and manufacturing process. In CAD and CAM, there is a tablet device that informs a computer program of necessary information from a rectangular menu sheet placed on the tablet.

In such a tablet device, not only the standard size menu paper but also enlarged or reduced menu paper can be used freely on the tablet device, which improves the storage and operability of the menu paper. It is strongly requested from this point of view.

(C) Prior Art and Problems The size of the rectangular menu paper used in conventional tablet devices is constant. That is, a menu paper a of that size is placed on the tablet b (see Figure 1), and the three points P1 + P2 + P3 are input in this order to create the menu paper that has been input and stored in advance. is compared with the paper data (see Figure 2), and Pl is determined to be P, Pa is determined to be Pb, and P3 is determined to be Pc.
#L 11 123 If it becomes object L2, the position (x, y) on the menu paper that is input after that is (X, Y)
It is determined that this is the case (assuming that there is no rotation of the paper) and the process proceeds, but if it is not lu#L,,+7!2s#L2, it will be treated as an error and no further processing will be performed. There is.

In other words, this tablet device has a restriction that the menu paper must be of a size determined by the device, which causes various problems.

(→Purpose of the Invention The present invention has been made in view of the above-mentioned drawbacks of the conventional device.The purpose of the present invention is to provide a standard menu paper that can be set on a tablet without depending on the size of the menu paper. An object of the present invention is to provide a tablet device that can input location data.

g) Structure of the Invention In order to achieve this object, the device of the present invention includes a tablet, a storage device for storing dimensional data of a rectangular standard menu sheet, a position detecting means for the standard menu sheet, and a tablet for the tablet. A rectangular menu paper of any size that can be set is set on the tablet, and the paper magnification is set in response to the position data obtained by detecting the arbitrary position of the paper with the position detection means and the dimension data of the reference menu paper. and a calculation means for calculating the rotation angle, and a conversion for converting the position data into a value indicating the corresponding position on the reference menu paper in response to the paper magnification and rotation angle and the position data indicated by the position detection means and outputting the result. The device is configured to include means.

(F) Embodiments of the Invention The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 3 shows an embodiment of the invention. In this figure, 1
is a tablet, and 2 is a position detection means for a rectangular reference menu sheet. 3 is a storage device that stores dimension data for a rectangular standard menu sheet. 4 sets a rectangular menu paper of any size that can be read on the tablet 1, and calculates the paper magnification and size from the position data obtained from the position detection means 2 and the dimensional data of the storage device 3 regarding the arbitrary position. This is a calculation means to calculate the rotation angle. Reference numeral 5 denotes a conversion means that responds to the paper magnification and rotation angle from the calculation means 4 and the position data from the position detection means 2, converts the position data into a value indicating the corresponding position on the reference menu sheet, and outputs the converted value.

Next 1. The operation of the apparatus of the present invention having the above configuration will be explained.

Menu paper of any size that can fit into a tablet 1 6
cents on tablet 1 as shown in FIG. The three vertex coordinates of the menu paper 6 are P, + P2 + P3
are detected by the position detecting means 2 (step S1 in FIG. 4), and these are input to the calculating means 4.

Calculation means 4 calculates ' 12 + ' as shown in Figure 3.
23 +ρ, 3, and since these lengths and the paper are rectangular, find the correspondence between P11P21P8 in Fig. 3 and Pa, pb, and Pc of the standard menu paper shown in Fig. 5, and find the origin ( Step S2 in FIG. 4). and,
These data and the dimensional data Xo, Yo of the storage device 3
In response to this, the rotation angle θ of the paper set on the tablet 1, the paper magnification in the X direction, for example, the magnification MX, and the paper magnification in the Y direction, for example, the magnification My are calculated (step S3 in FIG. 4).

In this way, preparations for inputting each menu on the menu paper are completed.

When an arbitrary menu position (x, y) to be inputted on the menu paper is indicated by the stylus pen of the position detection means 2, the position is the menu that would be located if the menu paper was the reference menu paper. The converting means 5 converts and outputs the values X and Y corresponding to the position (step S4 in FIG. 5), and makes them available for use by a computer program connected to the tablet device.

In this way, even if the menu sheet set on the tablet l is a sheet other than the standard menu sheet, for example a reduced sheet, input can be made from that menu sheet. Therefore, it is advantageous in storing the menu paper and also improves its operability.

Note that the gist of the present invention will not be lost even if the calculating means 4 and the converting means 5 are replaced not only by hardware but also by software.

0) Effects of the Invention As described above, according to the present invention, ■ it is possible to use a menu paper that has been enlarged or reduced compared to the standard menu paper, ■ it is advantageous in storing the paper, and Effects such as improved operability can be obtained.
