Abstract

PURPOSE:To facilitate the setting of format, and to improve workability by making the setting means of the format of coordinate data to be outputted into the coordinate data in a digitizer for detecting coordinate. CONSTITUTION:The setting means of the format is made into the coordinate data, and a deciding means to decide whether the coordinate data is for setting the format or to be outputted to an external device is provided between an arithmetic operating means and a processing means. Then, when the coordinate data is to be used for setting the format, the deciding means stores this coordinate data in the prescribed position of a format table. Besides, when the coordinate data is to be outputted to the external device, it outputs the coordinate data to the processing means. Thus, the setting of the format becomes easy, and the workability becomes favorable.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a digitizer for reading coordinates.

[Conventional technology]

The digitizer receives the signal sent out by the signal source by the receiving means, calculates the position of the signal source from the received signal as coordinate data by the calculating means, and the processor R calculates the position of the signal source as coordinate data according to the format set in the format table. Process data and output to external device. In addition, to set the format for the format table, use one or more binary changeover switches as a setting means, and combine these to create a logical condition.The logical condition is stored in a predetermined position of the format table. I will do my best to let you know.

By the way, the above format includes not only coordinates such as the direction of coordinate axes and units of length, but also formats for matching with connected external devices, and there are dozens of items that need to be set. Extends.

For this reason, the changeover switch used is a combination of small changeover levers that are operated by the tip of a precision screwdriver or the like.

[Problem to be solved by the invention]

However, as described above, since there are many items to be set, the number of changeover switches is 10 to 20. Further, for example, there are cases where eight sets of nine logical conditions are configured by forming a set of three binary changeover switches, so the levers of the changeover switches are operated. Sometimes you have to keep a lever setting chart handy and check each lever one by one. Furthermore, as mentioned above, since the lever is small,
The problem was that it was difficult to operate and it took time to set the format.

SUMMARY OF THE INVENTION An object of the present invention is to provide a digitizer that solves the above problems, allows easy formatting, and has excellent workability.

[Means to solve the problem]

The above problem can be solved by using W1 standard data as the format setting means,
This problem can be solved by providing a determining means between the arithmetic means and the processing means for determining whether the coordinate data is for setting a format or is to be output to an external device.

[For production]

The determining means stores the coordinate data at a predetermined position in the format table when the coordinate data is used for format setting. Further, when the coordinate data is to be output to an external device, the coordinate data is output to the processing means.

〔Example〕

Figure wJ1 is a front view of an electromagnetic induction type digitizer showing a first embodiment of the present invention.

In the figure, 1 is a cursor, which generates a predetermined signal when an operation switch 2 arranged on the side is closed. 3 is the case. A digitizing surface 4 is placed on the front side of the case 30 and receives a signal generated by the cursor 1 through a sense line (not shown). Note that the digitizing surface 4 has the origin O at the bottom left.
There is. 5 is a push button switch for control. 6 is an output terminal to which an external device (not shown) is connected. A menu sheet 7 indicated by a two-dot chain line is printed on the surface of the digitizing surface 4, and as shown in FIG. 2, which is a partially enlarged view, format items that must be set are described.

FIG. 3 is a flowchart for explaining the operation, and 8 is a calculation means. 9 is a means of judgment. 10 is a writing means. 11 is a format table. 12 is a processing means.

The operation will be explained below.

First, the operation of setting the format will be described, taking as an example the case where the unit of length, which is one of the format setting items, is set to .

First, the pushbutton switch 5 is fixed in the closed state. Next, the tip of the cursor 1 is brought into contact with the edge of the menu sheet 7, and the operation switch 2 is closed.

The signal generated by the cursor 1 is received by the digitizing surface 4, and the tip position of the cursor 1, which is the source of the signal, is outputted to the calculation means 8 as coordinate data on the digitizing surface 4 with the origin O as a reference.

Here, since the pushbutton switch 5 is closed, the determining means 9 outputs the output coordinate data to the writing means 10.

The writing means 10 writes a format corresponding to the output coordinate data at a predetermined position in the format table 11. Thereafter, other format items are set in the same manner, and when the format setting work is completed, the pushbutton switch 5 is fixed in the open state.

Next, although the normal reading and scanning operations of outputting coordinate data to an external device are the same as before, they will be explained just in case.

A drawing or the like is placed on the digitizing surface 4, the tip of the cursor 1 is brought into contact with the position where reading is required, and the operation switch 2 is closed. The signal generated by the cursor 1 is received by the digitizing surface 4, and the arithmetic means 8 outputs the position of the tip of the deer crane 1 as coordinate data. Here, since the pushbutton switch 5 is open, the determining means 9 outputs the output coordinate data to the processing means 12 as is. Processing means 12
processes the coordinate data according to a format set in the format table 11 and outputs it to an external device.

In this embodiment, the menu sheet 7 is printed on the digitizing surface 4, but it goes without saying that it may be configured as a separate sheet and placed on the digitizing surface 4 only when setting the format.

FIG. 4 is a front view of an electromagnetic induction type digitizer showing a second embodiment of the present invention, and FIG. 5 is a flowchart for explaining the operation of the second embodiment.

Note that the same parts as in Figures WJ1 to WJ3 are given the same reference numerals.

In the figure, 15 is a second digitizing surface used only for setting the format, the origin O is the same as the digital quiz surface 4, and the menu sheet 7 is printed. 16 is a judgment means.

The determining means 16 in this second embodiment is based on the calculating means 8.
It is determined whether to output the coordinate data to the writing means 10 or the processing means 12 based on the value of the coordinate data output from the coordinate data. That is, in FIG. 4, if the Y-axis is set upward from the origin O as indicated by the arrow, and the upper limit of digitizing 4 is Y4, the determining means 16 determines the Y-coordinate value Yn of the coordinate data output from the calculating means 8. If Y4 is exceeded, Y4 is written to the writing means 10.
In the following cases, it is output to the processing means 12. Other operations are substantially the same as those in the first embodiment, and will therefore be omitted.

In the above two embodiments, the format corresponding to the coordinate data is written in the format table 11 using the writing means 10, but the coordinate data is directly written in the format table 11.
It goes without saying that the coordinate data stored in the format table 11 may be stored in a format, and the conversion means 12 may have a function of converting the coordinate data stored in the format table 11 into a format.

Furthermore, it goes without saying that the present invention is applicable not only to electromagnetic induction type digitizers but also to other types of digitizers such as magnetostrictive type, magnetic detection type, and touch panel type.

〔Effect of the invention〕

As described in detail above, according to the present invention, since coordinate data is used as the format setting means, format setting is easy and workability is excellent.
