Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a coordinate input device integrally equipped with a graphic display device, and more specifically, the present invention relates to a coordinate input device integrally equipped with a graphic display device, and more specifically, the present invention relates to a coordinate input device that is integrally equipped with a graphic display device, and more specifically, The present invention relates to the invention of a coordinate input device that is integrally equipped with a graphic display device that can display a specified graphic drawn at its original size in real time.

[Conventional technology]

As is well known, a coordinate input device called a digitizer is used. Specifically, a coordinate input board is provided within the outer frame, and electrical coordinate lines are formed along the X-axis and Y-axis on this coordinate input board. On the other hand, as a coordinate input means, specifically, a stylus pen, a cursor, etc. are provided.

When inputting figures etc. using the above coordinate input device,
The coordinate input means is used to specify a position on the coordinate input board, and at that time, the position information is read, and the position information is stored and output.

By the way, if we take a closer look at the conventional technology, conventionally when a worker, designer, drawer, etc. draws a figure etc. on a coordinate input board using a coordinate input means, the information drawn is input to the computer side. The data is stored at the same time as it is displayed, and subsequent processing such as enlargement, reduction, and editing can be performed. In other words, a figure display device that displays figures, etc. that have been drawn so that the operator, etc. can visually confirm the figures, etc. that are currently being input by the worker, or because confirmation is necessary for work efficiency. is provided.

Specifically, there are CRT displays and the like.

However, the conventional graphic display device was connected to the coordinate input device by wire, and there was a graphic display device separate from the coordinate input device. On the other hand, in recent years, it is not only necessary to input, memorize, and output positional information specified on a coordinate input board using a coordinate input means, but also to input, memorize, and output information on a specified position on a coordinate input board. There has also been a demand for making drawn figures and the like immediately known to workers, and the above-mentioned prior art graphic display devices have only partially met this demand.

[Problem to be solved by the invention]

The above-mentioned conventional technology has the following problems.

That is, when a worker or the like draws a figure while specifying a position on the coordinate input board using a coordinate input means, although there are figure display devices that display the figure, etc., The figures, etc., were not the same size as the figures, etc. drawn by the worker, etc., that is, they were not the original size of the actual figures, etc., drawn by the worker, etc. More specifically, when a worker draws a figure by specifying a position on the coordinate input board using a coordinate input means, the length of the line segment actually drawn is displayed on the figure display. It was displayed in a reduced size on the screen of the device, and was not displayed in its original size. Therefore, although the worker can check the drawn figure on the figure display device, it is not displayed at the actual size of the figure drawn, so it is difficult to grasp the overall grandeur of the figure itself. there were. In addition, since a graphic display device is provided separately from the coordinate input board, when looking at the graphic display device, the worker uses the coordinate input means to designate a position on the coordinate input board and draw a graphic. This was a nuisance from the standpoint of work efficiency, as the operator had to take his/her line of sight off and shift it towards the graphic display device.

Therefore, an object of the present invention is to provide a method for when an operator draws a figure etc. by specifying a position on a coordinate input board using a coordinate input means and displays the drawn figure etc. on a figure display device. , the drawn figures, etc. are not only displayed in real time, but also displayed in the actual size of the drawn figures, etc., and moreover, the drawn figures, etc. can be displayed without changing the line of sight when drawing the figures, etc. To provide a means to check the vehicle.

[Means to solve problems]

In order to solve the above object, the present invention has the following technical means.

That is, to explain using the reference numerals in the attached drawings corresponding to the embodiments, the present invention includes a transparent coordinate input board 1 and coordinate input means 8, and the position on the transparent coordinate input board 1 is determined by the coordinate input means 8. In the coordinate input device 11, which can read position information on the transparent coordinate input board 1, store and output the position information by specifying the coordinate input board 1, the transparent coordinate input board 1 is made of a transparent insulator, and its Coordinate lines 9 are formed on the surface, and this transparent coordinate input board l
The figure display device is characterized in that it is integrally equipped with a figure display device 2 on the back side of the screen, which is capable of displaying figures etc. drawn on a transparent coordinate input board 1 by specifying the position using the coordinate input means 8 in real time at the original size. This is an integrated coordinate input device.

Further, it is considered that the graphic display device 2 is provided on the back surface of the transparent coordinate input board 1 over the entire surface of the transparent coordinate input board l.

Further, the graphic display device 2 is provided on the back side of the transparent coordinate input board l so as to be partially located with respect to the transparent coordinate input board 1, and is movable along the X axis 22 and the Y axis 23. It is considered that the

This eliminates the hassle of moving the line of sight to the figure display device 2 when drawing a figure or the like by specifying a position on the input board 1, making it easier to improve the efficiency of the work.
