Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an input/output device for information processing equipment using a transparent touch panel.

[Conventional technology]

In general, an input/output device using a transparent touch panel allows an operator to select necessary information from nine pieces of input information displayed on a display, as shown in Japanese Unexamined Patent Publication No. 55-72282. When a user touches a position corresponding to input information, a transparent touch panel attached to the display surface detects the position and input is performed. Traditionally, this touch panel was fixed to the surface of the display.

[Problem that the invention seeks to solve]

In the conventional transparent touch panel, a portion of the display capacity of the display device must be used to display input information. Therefore, it is useful for usages that require displaying a large amount of data on the screen, such as convenient usages such as word processors where inputted characters are displayed on a display device and editing work is performed while looking at the displayed characters. In addition to the transparent touch panel, a complete typewriter keyboard was required. In this case, a separate typewriter keyboard and an interface for connecting it to the main body of the information processing device are required, which has the drawback of increasing the price. Furthermore, adding a typewriter complete keyboard increases the volume of the entire device.

Therefore, the present invention eliminates the need for a conventional typewriter keyboard, makes maximum use of the ease of display on a display device, and allows information input/output without interfering with input operations. The purpose is to provide all possible input/output devices.

[Means for solving problems]

In order to solve the above problems, the present invention provides a display device that displays output display information from an information processing device on a screen, and a menu board that is installed adjacent to the display device and displays input information items. , a transparent touch panel of a size corresponding to the display screen size and menu board of the display device for detecting the coordinates of the pressing point;
Furthermore, the touch panel may be selectively movable on the display screen of the display device or on the menu board.

The structure that allows the touch panel device to be moved is, for example, a hinge that attaches the touch panel device 1 between the display device and the menu board so that it can rotate once. Thereby, the touch panel device can be moved like turning the pages of a book and placed either on the screen of display group 1 or on the menu board. The touch panel device is transparent, and you can see the information written on the menu board from the screen of the display device below, select the information to be input from there, and touch the position. A touch panel device detects the coordinates and input is performed. Since the touch panel device has a symmetrical structure on the front and back, it can detect touches applied from the front side and touches applied from the back side in the same way. You can input according to what is displayed on the display, and if you place it on the menu board, you can input according to the menu board.

[Effect]

According to the present invention having the above configuration, the touch panel can be selectively moved onto the display screen or the menu board of the display device, so that when the output information to be displayed on the display is satisfied. Even though
If you move the touch panel to the side of the menu board, it will not interfere with input operations, and if you move the touch panel above the display, you can process information display and input in parallel on the display. .

〔Example〕

An embodiment of the present invention will be described below. In FIG. 1, the input devices include a display device 1, a transparent touch panel 2,
It is composed of a rotation support section 3 and an input menu board 4. The display device 1 is a liquid crystal display, EL
The display may be a 7-rat panel display such as a plasma display, or a CRT display, but the surface of the screen is flat so that it can be brought into close contact with the touch panel 2.

The input menu board 4 may have information used for inputting characters, symbols, figures, etc. printed directly on its surface, or may be a sheet or card-like object on which the information is printed. It is a flat thin plate that is attached to a surface and is made of plastic or the like. The menu board 4 is placed side by side with the display device 1 so that its surface is on the same plane as the surface of the display device 1.

The structure for attaching the menu board 4 to the display device 1 is, for example, as shown in FIG. 2, in which both are rotatably coupled with a hinge 10 and a stopper 11 is provided. The mounting structure is not limited to this, and the display device 1 and the menu board 4 may be fixed or detachable. The rotation support part 3 is, for example, something like a hinge, and one end of the touch panel 2 is rotatably attached between the display device 1 and the menu board 4. Other methods of attaching the touch panel 2 can be considered; for example, a detachable type or a sliding type as shown in FIG. 3 may be used.

FIG. 4 shows an outline of the configuration of the touch panel 2. As shown in FIG. A plurality of X-coordinate detection electrodes 6X made of conductive material are placed parallel to each other at regular intervals (cover sea).
5a.

The cover sheet 5a is a sheet made of a transparent flexible insulating material such as polyethylene. The resistor 8Y is
It is made of a material with a uniform resistance value and is attached to the cover sheet 5a in contact with one end of all the X-coordinate detection electrodes 6X. Voltage detection electrodes cry-Ax are attached to both ends of the resistor 8Y. The cover sheet 5b is a sheet made of a transparent flexible insulating material like the cover sheet 5a.
The X-coordinate detection electrode 6X is placed on the surface facing the surface on which the detection electrode 6Y is attached at a certain interval in the direction orthogonal to the X-coordinate detection electrode 6X. It is installed in place. The resistor 8X is attached to the cover sheet 5b in contact with one end of all the X coordinate detection electrodes 6X. At both ends of the resistor 8X, there are electrodes 9X for voltage detection.
is installed.

FIG. 5 is a sectional view of the touch panel 2. The cover sheet 5a to which the X-coordinate detection electrode 6Xt is attached is kept clean for a certain period of time by the insulating protrusion 7 so that the detection electrodes are in contact with the cover sheet 5b to which the X-coordinate detection electrode 6X is attached. They are installed so that they face each other.

The insulating protrusion 7 is made of a transparent elastic insulating material, and is either integrally formed with the cover sheath 5a or on the surface of the cover sheath 5a. ! It is adhered to the surface of the target detection electrode 6Y. The insulating protrusion 7 may be attached to the cover sheet 5b or the X coordinate detection electrode 6X.

When pressure is applied to the front side of the touch panel 2 from the back side with a finger or the like, the cover sheet 5at or 5b deforms, and the X coordinate detection electrode 6X and the X coordinate detection electrode 6X of that part are brought into contact. At this time, by measuring the voltages of 1j9X and 9Y, the position of the electrodes in contact can be determined, and thereby the X and Y coordinates of the point where pressure is applied can be measured.

FIG. 6 shows a circuit used for coordinate detection.

motion? To explain, first, the input switching device 12 switches the conductor 1
The voltage V of the driving power source 14 is applied to the resistor 8X through the resistor 8X. Therefore, the resistor 8X has a constant potential depending on its position. When the touch panel 2 is touched, the X coordinate detection voltage % 6 X I and the X coordinate detection electrode 6X come into contact, and the i position corresponding to the position of the X coordinate detection electrode 6 Pole 6Y, resistor 8
The signal is inputted to an analog/digital converter/actual circuit 16 through a lead wire 15 and an input switching device 12 . At this time, by keeping all the input resistances of the analog-to-digital conversion circuit 16 closed, almost no current flows, so no voltage drop occurs across the resistor 8Y, and the voltage drops depending on the position of the resistor 8X. and the place are entered as is. The analog-to-digital conversion circuit 16 converts the difference between the input voltage and the reference voltage into a digital signal and outputs it to the primary M control circuit as information indicating the X-position drift of the contact point. Next, the input switching device n12 is switched, and this time, the voltage V is applied to the resistor 8Y through the conductor 15. The remaining operations are similar to those described above, and a digital signal corresponding to the Y coordinate of the contact point is output from the analog-to-digital conversion circuit.

Next, the operation of the entire input device will be explained. In FIG. 1, the transparent touch panel 2 can be placed on the menu board 4 at the top of the display device 1, like turning the pages of a book. When a touch panel is placed on top of the display device 1, input can be made according to a menu displayed on one screen. Next, when the touch panel 2 is stacked on the menu board 4, input according to the menu printed on the menu board 4 can be performed without sacrificing the display on the display device 1. Therefore, it becomes possible to freely select one of these two methods according to the purpose of use, and operability is improved.

In this way, in an input device using a touch panel,
Even if you cannot use a touch panel and need to add a mechanical keyboard because you need to display more data on a display device, you can add a menu board that is much smaller, cheaper, and simpler than a mechanical keyboard, and has a simple structure. , touch spring) yf Just use it as is,
Since input can be performed without using a display, an economical, space-saving, and multifunctional input/output bag can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, since the touch panel can be moved arbitrarily as appropriate, it is possible to fully utilize the display capability of the display and perform input operations, and it is also possible to perform input operations on the same screen. Information can also be input and output as desired.
