Abstract

PURPOSE:To easily obtain a three-dimensional coordinate by providing a controller and synthesizing two-dimensional coordinates due to cursor indication and coordinate data from a key input part of a cursor to obtain three-dimensional coordinates. CONSTITUTION:Two-dimensional coordinate values of a desired point on a tablet 11 on a plane plate are read by pointing of a cursor 12, and the coordinate value of the third dimension is outputted by the operation of ten keys 12b of the cursor 12. These coordinate values are synthesized by a controller 13 to obtain a three-dimensional coordinate value. Consequently, three- dimensional coordinates are easily obtained without passing a computer 14 or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coordinate reading device that reads coordinate values on a plane and inputs the coordinate values into a computer.

[Prior Art] A coordinate reading device (digitizer) is a device that reads the two-dimensional coordinate value of an arbitrary point on a flat plate (tablet) by picking it with a cursor (transmitter) connected to the tablet. It consists of a tablet, a cursor, and a controller to control the whole thing.

That is, the two-dimensional coordinate data read by the cursor on the tablet is sent to the third computer via the controller, where drawing processing and various technical calculations are performed.

Generally, a digitizer refers to a two-dimensional coordinate reading device, and a three-dimensional (three-dimensional) coordinate reading device is called a three-dimensional or three-dimensional digitizer.

For example, if you want to input three-dimensional coordinates into a computer using the two-dimensional digitizer, first input the three-dimensional coordinates using the CRT keyboard installed in the computer, and then wait for the computer to input two-dimensional coordinates. Set to state. Thereafter, the two-dimensional coordinate values read by the two-dimensional digitizer are manually processed into three-dimensional coordinate values by a computer. Alternatively, after inputting two-dimensional coordinate values into a computer, three-dimensional coordinate values are processed by manually inputting third-dimensional coordinate values into the computer using a CRT key.

[Problems to be Solved by the Invention] However, obtaining three-dimensional coordinate data using the coordinate input means described above requires inputting two-dimensional coordinate values using a two-dimensional digitizer and three-dimensional coordinate data using a computer keyboard. This requires a coordinate input operation between the two devices in addition to the coordinate input operation for the second dimension, and there is a drawback that the back and forth operation between each device is troublesome and causes a decrease in work efficiency.

The present invention has been made in view of the above-mentioned problems, and it becomes possible to easily obtain three-dimensional coordinate data without having to separately input two-dimensional coordinate values and third-dimensional coordinate values into a computer and process them. The purpose is to provide a coordinate reading device.

[Means and operations for solving the problem] In other words, the coordinate reading device according to the present invention indicates an arbitrary point on a plane with a cursor and reads this indicated point as two-dimensional coordinates. It is equipped with a key input section for inputting coordinate data, and a controller for synthesizing the coordinate data input by the key input section of the cursor and the two-dimensional coordinates read by the cursor instruction to obtain three-dimensional coordinates, and only the cursor can be operated. The three-dimensional coordinate values are obtained and input to the computer.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 shows its configuration. In the same figure, numeral 11 is a flat tablet for inputting two-dimensional coordinates, and numeral 12 is a flat tablet for inputting two-dimensional coordinates, and numeral numeral coordinates are picked up by moving on a plane to pick up two-dimensional coordinate values on the tablet 11. The cursor is equipped with a numeric keypad 12a for input and a display 12b for displaying key data manually, and signal lines of the tablet 11 and cursor 12 are connected to a controller 13. This controller 13 synthesizes the two-dimensional coordinate value on the tablet 11 picked up by the movement operation of the cursor 12 and the third-dimensional coordinate value input manually using the numeric keypad 12a of the cursor 12, and generates a three-dimensional coordinate value. This three-dimensional coordinate value is output to the computer 14, and graphic creation processing or arithmetic processing is executed as appropriate. Note that 14 is a CRT keyboard.

That is, in the coordinate reading device having the above configuration, two-dimensional coordinates on the tablet 11 are specified by moving the cursor 12, and coordinates in a direction perpendicular to the surface of the tablet 11 are input using the numeric keypad 12a provided on the cursor 12 itself. The three-dimensional coordinate values are obtained by combining the respective coordinate values using the controller 13. Therefore, the user can obtain the three-dimensional coordinate values only by using the cursor 12.

Therefore, according to the coordinate reading device having the above configuration, two-dimensional coordinate values are inputted using a digitizer, and third-dimensional coordinate values are inputted using a CRT keyboard of a computer, as described in the above-mentioned [Prior Art]. , work efficiency can be improved without the hassle of input operations at the separated position, and the three-dimensional coordinate values can be transferred from the controller 13 as one data to the computer 1 in the final data format.
4, it is also possible to simplify the processing content on the computer 14 side.

C. Effects of the Invention As described above, according to the present invention, any point on a plane is indicated with a cursor, and this indicated point is read as two-dimensional coordinates, and the key provided on the cursor is used to input coordinate data. The input section, the coordinate data input by the key input section of this cursor, and the coordinate data read by the cursor instruction.
Equipped with a controller that synthesizes dimensional coordinates and obtains 3-dimensional coordinates, the 3-dimensional coordinate values are obtained only by cursor operation and the computer is manually operated, so the 2-dimensional coordinate values and the 3-dimensional coordinate values can be separately input to the computer. It is possible to provide a coordinate reading device that can easily obtain three-dimensional coordinate data without inputting and processing.
