[Industrial application field]

The present invention relates to a drawing input/output device that is used by being connected to a switching device, and more particularly to a drawing input/output device that allows use of both sides of a transparent tablet left.

In recent years, with the remarkable progress of communication devices, drawing input/output devices have become indispensable for simultaneous drawing communication terminals and videotex original drawing devices, etc., along with voice.These drawing input/output devices draw directly on the display with a handwriting pen. There are two forms: one form and one form in which drawing is input by tracing 16 images on existing paper, etc.

[Conventional technology]

Fig. 4 is a diagram explaining a conventional drawing input/output device, and Fig. 4 (ta) is a perspective view of an integrated tablet left and display;
(bl is a perspective view of a separated doublet and display.

In FIG. 4(a), a transparent tablet 3 is stacked on a flat display 2 attached to a main body 1, and is equipped with a handwriting pen 4 and a handset 5. Then, while making a voice call using the handset 5, drawing can be performed on the transparent tablet 3 using the handwriting pen 4, thereby simultaneously communicating voice and images.

In FIG. 4 (1)), an opaque tablet 7 is provided separately from a main body 1 to which a CRT display 6 is attached, and the CRT display 6 attached to the main body 1 and the opaque tablet 7 are electrically connected. 1 is equipped with a handset 5, and an opaque tablet 7 is equipped with a handwriting pen 4. Then, while making a voice call using the handset 5, drawing can be done on the opaque tablet 7 using the handwriting pen 4, thereby allowing simultaneous voice and image communication.

[Problem that the invention seeks to solve]

Among the above-mentioned conventional drawing input/output devices, in a device in which a transparent tablet left is placed on top of the display, when you want to input a drawing by tracing a drawing image written on paper or the like on the transparent tablet, the image is displayed on the display. However, in devices where the CRT display and the opaque tablet are separated, the user must move his/her line of sight between the display and the doublet in order to check the drawings written on the opaque doublet, and partial erasure may occur. When doing this, there were problems such as the drawings drawn on paper and the drawings displayed on the display did not match.

[Means for solving problems]

The present invention solves the above-mentioned problems and provides a drawing input/output device that allows use of both sides of the transparent tablet left, i.e., when the transparent tablet is stacked on the display and when the transparent tablet is separated (turned over). It is something.

That is, a drawing input/output device comprising a transparent tablet 8 that detects an image drawn by the handwriting pen 4 and outputs a coordinate signal, and a display 2 that displays a drawn image corresponding to the inputted drawing information is connected to the display 2. A state in which the transparent tablet 8 is stacked on top of the display 2, and a state in which the transparent tablet 8 is separated from the display 2 by being turned over toward the main body using an opening/closing member 9 such as a hinge, and the transparent tablet 8 is separated from the display 2. A Y-coordinate converter 15 converts the coordinates of the transparent tablet 8 so that the trajectory of the handwriting pen 4 drawn on the transparent tablet 8 and the drawn image displayed on the display 2 are not mutually reversed; Tablet status detection unit 1 that detects the status of tablet 8
This problem is solved by providing 3.

[Effect]

The above-mentioned drawing input/output device is designed so that the transparent tablet left stacked on the display is turned over toward the main body using an opening/closing member such as a hinge so that it is separated from the display. You can place a drawing on a piece of paper underneath and input it by tracing it, so it can accommodate a wide variety of requests.

〔Example〕

FIG. 1 is a diagram illustrating an embodiment of the present invention.

(b) is a perspective view of the display and the transparent tablet separated, in which the same parts as in FIG. 4 are given the same reference numerals.

In FIG. 1(a), a transparent tablet 8 is stacked on the display 2 provided in the main body 1, and the transparent tablet 8 and the main body 1 are placed on top of each other.
is attached so as to be openable and closable with an opening/closing member 9 made of a hinge or the like, and the main body 1 is further equipped with a handwriting pen 4 and a handset 5. Then, while making a voice call using the handwriting pen 5, you can draw on the transparent tablet 8 with the handwriting pen 4, or place a piece of paper with the drawn image on the transparent tablet 8 and trace it with the handwriting pen 4 to simultaneously communicate voice and images. I can do it.

FIG. 1(b) shows a transparent tablet 8 separated from the display 2 from the main body 1 by turning it over toward the front with respect to the main body using an opening/closing member 9 made of a hinge or the like. Therefore, the drawing with the handwriting pen 4 is inputted on the back side of the transparent tablet 8, contrary to FIG. , the selector 10 is operated.By separating the transparent tablet 8, the button switch 11 changes from the ON state to the OFF state, which is detected by the tablet state detection section 1.
3 is detected and can be switched by controlling the selector 10. Then, while making a voice call using the handset 5 attached to the main body 1, you can draw on the transparent tablet 8 with the handwriting pen 4 or place the drawn image on a piece of paper and trace it with the handwriting pen 4 to simultaneously communicate voice and images. I can do it.

In this way, it becomes possible to place an image written on existing paper on top or bottom of the transparent tablet 8 and trace it with the handwriting pen 4.

FIG. 2 is a block diagram of the drawing input/output device of the present invention, in which the same parts as in FIG. 1 are given the same reference numerals.

If input is made using a handwriting pen (not shown) on the transparent tablet 8 (when the transparent tablet left overlaps the display), it will be displayed on the display (not shown) via the solid line of the button switch 10 without passing through the Y coordinate conversion section 15.
The image input to the transparent tablet 8 is displayed as it is. If you separate the transparent tablet left from the display, the transparent tablet left will turn over and the transparent tablet 8 will turn over.
' (back side), the selector 10 changes from a to b.
If you switch to the selection and enter it on the transparent tablet 8' with a handwriting pen (not shown), the Y coordinate signal will be converted to the Y coordinate conversion section 1.
