Abstract

PURPOSE:To mask an original with the high degree of freedom and to prevent the position of a mask image from being deviated to characters on an original by generating the mask image to be displayed on a mask image display panel based on coordinates detected by a coordinate detecting means. CONSTITUTION:By using the keyboard of a document preparing device, input of the first line of a document is started and when the preparation of the document for one line on the original is completed a document preparing person designates the coordinates of an a1 (X1,Y1) on a transparent tablet 3 by a pen or a finger, etc. Based on the coordinate data from the transparent tablet 3, a mask image generation part 9 displays the mask image on a mask image display panel 2 over the range of X1 in the X axis direction and Y1 in the Y axis direction with coordinates (0, 0) at the upper left end of the mask image display panel 2 as an origin. Thus, the original can be masked with the high degree of freedom such as masking in the middle of the line or the like, and there is no problem to deviate the position of the mask image to the characters on the original.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a document table device used in document input work of a document creation device such as a word processor.

(Prior Art) Conventionally, in document input work using a document creation device such as a word processor, in order to be able to identify at a glance inputted areas and uninputted areas on a manuscript, for example, Previously, the completed area was masked in some form, for example, with a marker pen.

Therefore, each time a document creator performs such a masking operation, he or she has to take his or her finger off the keyboard of the document creation device to interrupt the input operation, making it impossible to perform the input operation efficiently.

Recently, a document table device has been commercialized in which a transparent display panel is placed above the document and a mask image is displayed in the middle of the line at a position on the display panel that corresponds to the area where the document has been input.

However, most of these document table devices only display a mask image line by line, and do not mask the middle of a line.

Therefore, especially when a document with a large number of characters per line is loaded, a satisfactory masking operation cannot be performed.

Further, even if it is possible to display a mask image for each character, misalignment between the original characters and the mask image often occurs due to uneven character spacing on the original.

(Problems to be Solved by the Invention) The present invention is intended to solve such problems, and allows masking to be applied to the original with a high degree of freedom, such as applying a mask to the middle of a line. It is an object of the present invention to provide a document table device which does not have the problem of misalignment of a mask image with respect to upper characters.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above-mentioned objects, the manuscript table device of the present invention has the following features:
A document placement plate on which a document to be created by the document creation device is placed, and a document placement plate on which the document is sandwiched and stacked, corresponding to an area on the document that has been created by the document creation device. A transparent mask image display panel for displaying a mask image at a position, a coordinate detection means arranged on the mask image display panel, and a mask image display based on the coordinates detected by the coordinate pressure detection means. and mask image generation means for generating a mask image to be displayed on the panel.

(Function) In the document table device of the present invention, the mask image generation means
Since a mask image to be displayed on the mask image display panel is generated based on the coordinates detected by the coordinate detection means, the document can be masked with a high degree of freedom, such as masking up to the middle of a line character by character. This also eliminates the problem of misalignment of the mask image with respect to the characters on the document.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIGS. 2 to 4 are a front view, a side view, and a plan view, respectively, of a document table device according to an embodiment of the present invention when viewed from three directions.

In these figures, 1 is a document placement plate on which a document P to be created using a document creation device (not shown) is placed, and 2 is a document placement plate on which the document P is placed on one side of the document placement board 1. This is a transparent mask image display panel made of a liquid crystal display or the like, which is arranged so as to be sandwiched and overlapped, and displays a mask image at a position corresponding to an area on the document P that has been inputted by the document creation device. 3 is the mask image display panel 2
This is a pressure-sensitive transparent tablet placed on top of the coordinate detection means. Further, 4 is a base for stably placing this document table device on a desk or the like, 5 is an extension support part for supporting the document placement plate 1 in an extended position on the base 4, and 6 is a base for supporting the document table 1 on the base 4. For example, extend the extension support part 5 from 45 to 9 in the clockwise direction in the figure with respect to the installation surface of the base 4.
A first angle adjustment connection part 7 (which connects the original angle adjustment connection part 7 so that the angle S can be adjusted in the range of 0 degrees) connects the document placement plate 1 to the extension support part 5, for example, in the clockwise direction in the figure with respect to the installation surface of the base 4. 90-13
This is a second angle adjustment connection part that connects the angle adjustment in a range of 5 degrees. 8 displays the mask image on the mask image display panel 2 line by line, as shown in FIG.
This is an external mask designation device equipped with an UP key 8a and a DOWN key 8b for deletion.

FIG. 1 is a block diagram showing the configuration of characteristic parts of this document table device.

In the figure, 2 and 3 are the above-mentioned mask image display panel and transparent tablet, respectively, and 9 is based on the coordinate data A input from the transparent tablet 3 or the UP/DOWN signal B input from the external mask designation device 8. This is a mask image generation unit that generates a mask image C to be displayed on the mask image display panel 2.

Next, the operation of the document table device of this embodiment will be explained with reference to FIGS. 6(a-d).

First, a document P to be created is placed on the document placement plate 1. Next, the mask image display panel 2 and the transparent tablet 3 are stacked and fixed on this document placement plate 1 with the document P sandwiched between them, and the first angle adjustment connection section 6 and the second angle adjustment connection section 7 are adjusted. and set the mask image display panel 2 in a direction that is easy for the document creator to view.

After that, as shown in FIG. 6(a), start inputting the first line of the document using the keyboard of the document creation device,
When the document creator has finished creating one line of the document P, the document creator or a1 (XI, Yl) on the transparent tab 1 note 3
When you specify the coordinates of the upper left corner of the mask image display panel 2 on the basis of the coordinate data from the transparent tablet l-3, the mask image generation unit 9 specifies the coordinates of the upper left corner of the mask image display panel 2 (
0,0) is the origin and 17 is X co in the X axis direction and Y in the Y axis direction.
] The mask image is displayed on the mask image display panel 2 within the range.

After this, when masking the next line after the second line of the document P, use the sixth
As shown in Figure (1)), the document creator similarly specifies the coordinates of a2 (, x:2.Y2) on the transparent tablet 3. As a result, the mask image generation unit 9 additionally displays a mask image on that part if there is a part in the range from O to ,0) in the X-axis direction
2. Display the mask image on the mask image display panel 2 within a range of Y2 in the Y-axis direction.

Furthermore, Figure 6(C) shows the case where a mask image of the same width (7 widths) is added to a line that is partially masked [2
ing. In this case, specify 1. Taa2(X2.Y2)
For example, a3 (X3.Y2
) on the transparent tablet 3. As a result, the already displayed mask image and the origin coordinate (0
, O) with a mask image in the range of X3 in the X-axis direction and Y2 in the Y-axis direction, and the mask image is displayed on the mask image display panel 2.

Further, FIG. 6(d) shows a case where the user wishes to refer again to a line 17 of the document P that has already been masked. In this case, for example, a4
The coordinates of (X4.Y4) are transparent tabreso 1-3 J-,
Specify with. As a result, all mask images except for the range X4 in the X-axis direction and Y4 in the Y-axis direction from the origin coordinates (0, O) are deleted, and the desired line on the document P can now be recognized.

Next, the operation when performing a mask operation using the external mask specifying device 8 will be explained.

When the mask image generation section 9 receives the IIP/DOWN signal from the external mask designation device 8, it displays and deletes the mask image line by line on the mask image display panel 2. In this case, the line width of the mask image is equal to the width of the mask image initially designated using the transparent tablet 3 after the document is placed. For example, as shown in FIG. 7, by pressing the UP key 8a of the external mask specifying device 8 once, the bottom line of the mask image or one line is deleted, and by pressing the DOW N key 8b once, the next mask image is deleted. An additional mask image will be displayed that fills the entire line up to the line.

Thus, according to the document table device of this embodiment, a desired area on the mask image display panel 2 can be masked by simply specifying arbitrary coordinates on the transparent tablet 3. Masking operations can be performed on the original P with a high degree of freedom, such as being able to mask up to the middle of a line. Furthermore, the problem of misalignment of the mask image with respect to the characters on the document is also eliminated.

In this embodiment, a pressure-sensitive transparent tablet 3 is used, but an electrostatic induction type or electromagnetic induction type transparent tablet may also be used.

[Effects of the Invention] As explained above, according to the document table device of the present invention, it is possible to mask a document with a high degree of freedom, such as masking the middle of a line character by character, and The problem of misalignment of the mask image with respect to the characters on the original document is also eliminated.
