Abstract

PURPOSE:To discriminate between a desired key and the other keys and to improve the operability of key input by discriminating and displaying only inputtable keys determined by the processing of a processing means. CONSTITUTION:An operator sets the functions, display colors, and ECR modes of respective keys are used to a key table 20. Next, a mode switch SW 24 is operated to select a desired ECR mode. A main CPU 23 detects this mode and transfers the information of areas I-III, where mode information stored in an area IV of the table 20 and selected at present is stored, to a RAM 25 in accordance with the program preliminarily stored in a ROM 22. The CPU 23 controls a panel control means 26 in accordance with the program in the ROM 22 based on information in the RAM 25 to read out respective segments and display colors. Picture element positions are selected by horizontal and vertical controls and only inputtable keys on the input panel 2 are discriminated and displayed through a driving circuit 30 in the color designated by a color control means 29.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a key input device used in a computer terminal or the like.

<Prior Art> A key input device with a curved prior art mode switching function has a plurality of input operation keys, a mode switching key, and a Fura I! These keys are used to perform input operations.

The input data is displayed on the display screen, and the operator confirms the specific output displayed on the screen and inputs the next step. In such an input operation, the operator selects the next mode to be executed, identifies the keys in nine areas related to that mode, and then constantly takes care not to operate keys used in other modes. An input operation is performed. In such conventional key input devices, each input key is
Since there is no display that allows identification of the mode in which the input operation is being performed, the operator must memorize the mode and perform the input operation. This often results in input errors. In order to solve this problem, in the past, a pilot lamp was attached to the mode key, and the selected T mode was identified by lighting the pilot lamp.

<Problems to be Solved by the Invention> However, in such a method, only the mode key in use is identified, and the input key selected by that mode key is not identified at all. To essentially reduce input errors caused by the use of keys having multiple functions when inputting a large amount of data while switching mode functions, which may occur due to the confusion of the status of other functions. The present invention was made in view of the drawbacks of the conventional technology, and it is possible to identify and display only the keys that can be used in the process according to each process state, and to distinguish a desired key from other keys. It is an object of the present invention to provide a t-key input device that enables the user to input the keys manually and improves the operability of the keys manually.

Means for Solving the Problems> The present invention provides a key input device including a color liquid crystal display means and a transparent sheet switching input means mounted on the color liquid crystal display means. a key table means for storing the function 0 display color etc. of each key; a memory means for storing various processing programs; The present invention is characterized in that it comprises a processing means for performing processing, and only input-enabled keys determined by the processing of the processing means are identified and displayed.

Function> When the key input device of the present invention is set to a desired mode of the processing means, it detects this mode and inputs the selected t stored in the key table means in accordance with a pre-stored procedure.
The mode information is transferred to and stored in the storage means, and processed by the processing means in accordance with a program previously stored in the memory means.

Therefore, in this device, only the keys used in that mode are identified and displayed, making it possible to distinguish a desired key from the pond key, and improving the operability of the keys manually.

<Embodiment> FIG. 1 is a perspective view of a terminal device 50 such as a computer equipped with a key input device l according to the present invention, and FIG. FIG. The terminal device 50 has a key input device 1 and a display device 3 that displays t data inputted by the key input device 1. An input cover panel 2 is provided on the top surface of the key input device l, and this input cover panel 2 consists of a color liquid crystal display board 4 and a touch panel 5 mounted on the color liquid crystal display board 4 and serving as a sheet switch input means. There is. The color liquid crystal display panel 4 consists of two upper and lower glass substrates 6. 1O is turned on, and nine signal lines 17 are formed on the lower glass substrate 6 in a matrix pattern. This signal electric machine 7 consists of a thin film transistor array 8 and a liquid crystal drive electrode 9.

Laminated on the lower surface of the upper glass substrate 10 are a color filter 11 composed of eight primary colors of red, blue, and green, and a common electrode 12 that serves as the tth counter electric machine for driving the liquid crystal.Color filter No. 11 is capable of full-color display by controlling the amount of light passing through each of the three primary colors, and one pixel is composed of the three primary colors of red, green, and blue.Such a color filter IItI' i, 7t is formed by dyeing method, and is made of gelatin etc.
It is formed by patterning L' into a pixel shape by photolithography and then dyeing it with a dye. A liquid crystal 18 is filled between the common electrode 12 and the signal electrode 67 in close contact with the color filter 11, thereby forming the color liquid crystal display panel 4. A touch panel 5 consisting of two upper and lower transparent sheets 14 and 15 is mounted on the color liquid crystal display panel 4 formed in this manner, thereby forming the cover panel 2.

, the currently selected t mode information is transferred and stored in the RAM 25 (S6), the key panel is controlled by the panel control means 26 based on this information (S7), and only the keys to be used in that mode are identified and displayed (S8). After that, the operation is as usual (S9), no matter which mode you select, 8
Operations 5 to S8 are performed. The designated head area is displayed in the designated color as described above, and this cover panel 2 is made operable. When a predetermined area (for example, area a) of the key panel 19 is pressed, the position of the pressed area is detected by the position detection means 31, and the area signal a is inputted to the panel control means 26. Upon receiving this area signal, the panel control means 26 refers to the RAM 25, checks where the area signal is stored, reads out the function hood of the area key in the row where the area signal was stored, and reads the main Transfer this main C to CP02B
