Abstract

PURPOSE:To execute efficiently digitization by providing plural coordinate converting parameter memory parts to one tablet, dividing it into plural zones, and executing independently coordinate conversion. CONSTITUTION:A controller is connected to one tablet 1 provided with a coordinate indicator, and this controller is provided with a CPU5, a program memory part 6 and a data memory part 7, and also a coordinate converting parameter memory part 8 corresponding to each zone 11A-11D, etc. As a result, as for a coordinate generated by the coordinate indicator, to which zone of plural divided zones 11A-11D it belongs is discriminated, and for instance, when it belongs to the zone 11A, said parameter memory part 8 corresponding to it is called out, a coordinate conversion is executed by its parameter, and thereafter, processing of formating, etc. is executed, and it is outputted to an interface. In this way, the plate surface of one tablet can be brought to a coordinate conversion independently at every zone.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coordinate reading device, and more particularly to a coordinate reading device including a plurality of coordinate conversion parameter memory units in one tablet.

Conventional coordinate reading devices do not have any parameter memory section for coordinate transformation, or only have a single parameter memory section for coordinate transformation, so the coordinates can be read by digitizing the digitized coordinate values according to the drawing being digitized. In some cases, the coordinates cannot be converted, or only one coordinate conversion can be performed on the entire tablet surface.

In order to solve the above-mentioned drawbacks, the present invention provides one tablet with a plurality of parameter memory sections for coordinate transformation, divides one tablet board surface into a plurality of zones, and independently performs coordinate transformation within each zone. The object of the present invention is to provide a coordinate reading device that can perform the following operations.

A perspective view of a coordinate reading device for explaining the present invention is shown in FIG. 1, a circuit block diagram around a CPU is shown in FIG. 2, and a schematic flowchart of processing is shown in FIG. 3.

In FIG. 1, 1 is a tablet, 2 is one or more coordinate indicators provided on the tablet 1, 3 is a pedestal that supports the tablet 1,
4 is a controller connected to or built into the tablet 1.

FIG. 2 shows a CPU built in the controller 4.
In the peripheral circuit block diagram, 5 is a CPU section, 6 is a program memory section, 7 is a data memory section, 8 is a coordinate conversion parameter memory section corresponding to each zone, and these are a data bus 9 and an address bus 10. are connected by.

The processing procedure will be explained according to the flowchart in FIG.

The coordinates generated by digitizing with the coordinate indicator 2 are determined to which zone among the plurality of zones they belong to, and if the coordinates belong to the Nth zone, for example, coordinate transformation corresponding to the Nth zone is performed. After calling the parameter memory section N and performing coordinate transformation using the parameters stored therein, formatting and other processing are performed, and output to the interface. In this way, when one tablet surface is divided into multiple zones, it becomes possible to perform completely independent coordinate transformation for each zone, and one coordinate reading device can read the coordinates of multiple devices. It can be used as if it were a device.

FIG. 4 shows an embodiment of the present invention, showing four zones 11A separated by broken lines on the surface of the tablet 1.

This is an example of dividing into 11B, 110.11DK. Said 4
The four zones 11A, 11B, 110, and 11D have four drawings 12A, 12B, and 120°12D, respectively, and the coordinate values 13A, 1 of the origin are independent for each zone.

The coordinate values generated by the parameters to be converted to the origin are converted therein.

Note that the coordinate transformation in the present invention is not limited to setting the origin, but can also be applied to many other coordinate transformations such as rotation of coordinates, and complex transformations thereof. It is 4.

As described above, according to the present invention, coordinate transformation can be performed independently on multiple drawings on one tablet, so multiple drawings in different zones can be converted to the same office/space. By overlapping them or using multiple coordinate indicators, one coordinate reading device can be used as several independent coordinate P-claw devices, improving cost performance and digitizing efficiency. , is effective for analyzing more complex drawings, etc.
