Abstract

PURPOSE:To simplify the reading of a message and the recognision of a monitor picture, by superposing a tranparent monitoring display plate part to an input picture part to make it possible to observe input and output pictures from the same visual field. CONSTITUTION:An original 12 is put on the input picture part 14 and a display part 10 is closed in the direction of an arrow to superpose the display part 10 to the input picture part 14. The display part 10 is composed of a transparent film such as liquid crystal and also provided with electrodes coincident with the electrodes arrayed in the x and y axis directions on the input picture part 14 like a grid. When the original is indicated by a stylus pen 18 from the surface of the film of the display part 10, the graphic is detected by the input picture part 14 and the output signal is supplied to an unshown CPU through a controller 20. The controller 20 drives the display part 10 on the basis of the positional information processed by the CPU to display the picture inputted by the stylus pen 18. Consequently, the input graphic 12 is superposed to the monitor graphic, so that an input error is easily detected and the input stopped on the way is easily continued.

Description

[Detailed description of the invention] The present invention relates to a graphic input device for handwritten input.

In recent years, with the development of computers, the diversification of data processing has progressed, and there has been a desire to input figures by hand. BACKGROUND ART Conventionally, graphic input devices for handwriting input called tablets and digitizers have been used as f3+4. These devices generally consist of an instruction section called a stylus or cursor, and an input screen section that supports a predetermined coordinate system and outputs positional information of the indicated point, and in some cases, a display section for a monitor such as a CRT. combined with Input ■ Output of 1st side (
The i number is supplied to a graphic processing device such as a computer. The signal that has undergone predetermined processing in the graphic processing device is supplied to the display section, where the input graphic is displayed and input errors and the like are recognized. In addition to this, the display unit may display messages that instruct the operator to perform operations. in this way,
The display section provides the operator with useful information regarding the operation.

However, in conventional devices, the input ilI! +
Since the U#: section and the display section are spatially apart, in order to read the message Mt or check the monitor image,
It is necessary to move 1fM. This may cause erroneous operation. Also, in the case of an input error, it is necessary to re-enter the input from the point where the error occurred, but this input? In addition to not being able to accurately determine the location of IJ opening,
The drawback is that it takes time to make this decision.

This invention was made to deal with the above-mentioned circumstances,
The purpose is to provide a graphic input device in which the monitor display section and the double-sided input section can be viewed in the same field of view.

The purpose of this is to input i! This is realized by overlaying a translucent display section on one surface.

Hereinafter, one embodiment of a graphic input device according to the present invention will be described with reference to the drawings. FIG. 1 and FIG. 2 are both perspective views of this embodiment, and each shows a case in which the flat translucent display section 10, which also serves as a document cover, is ridged when closed.

For example, there is one input screen section 14 on which the original figure 12 is placed.
It has electrodes arranged in a grid pattern in the x-y axis direction.

The input screen is spatially quantized. One side of the display section 10 is connected to one side of the input screen section 14 by a hinge, and after placing the original figure 2 on the input screen section 14, the first
As shown in the figure, hold the original figure 12 in the input screen section 4.
It is connected to The vertical movement of the display section 10 and the input screen section 14 is smoothly performed by a spring 16. The display section JO is made of a translucent material such as liquid crystal or electrochromic, and has the same coordinate axes so as to exactly overlap the coordinate axes of the input screen section 14. In the state shown in FIG. 1, when a point in the figure is specified with the stylus pen 18, a magnetic field is generated from the stylus pen J8, and the input screen @l5
74 detects this point and outputs a signal representing the position of the point constituting the original figure. The thickness of the display @SXO is
It is set so as not to interfere with the detection of this magnetic field. input i1
The output signal of the 1+1 side section No. 4 is supplied to the controller 20 and further to a computer (not shown).

On the other hand, the controller 20 moves the display unit 10 based on position information processed by the computer. This results in
A graphic input using a stylus pen 18 is displayed on the display unit 10. Here, if the coordinate axes of the display section 10 are exactly aligned with the coordinate axes of the input screen section 4, a figure that exactly overlaps with the original figure 12 will be displayed unless there is an input error. Therefore, the input i 31 quickly becomes
And it can be done accurately. Furthermore, even if input is interrupted midway, the point at which re-input is to be started can be easily detected. Here, if the color of the display unit 10 is made different from the color of the original graphics, this input confirmation can be easily performed.

As described above, according to this embodiment, by placing a translucent display section JO on the input screen section J4 and inputting the original figure 12 with the stylus pen 18 via the display section JO,
A graphic input device capable of convenient monitor display is provided.

The present invention is not limited to the embodiments described above, and the graphic input method, type of display section, etc. can be changed in various ways. In particular, regarding the graphic input method, any type that can be detected even when the translucent display section 10 is held in between (iiJ is also acceptable). 7. In this case, the display section may be placed on the opposite side of the projection side and may be glued to the input rl! Instead of displaying , a predetermined symbol % pattern or message may be displayed.

As described above, the present invention provides a graphic input device in which the input screen section and the display section can be viewed in the same field of view.
