JPS6045832A - Computer key displaying function with variable picture - Google Patents

Abstract

PURPOSE:To prevent misoperations of a key having plural functions and to improve the operating efficiency by displaying functions on the surface of the key or at the periphery of the key in the form of variable pictures using liquid crystal. CONSTITUTION:A variable picture device 2 using liquid crystal is set on the surface of a key 1 provided on a keyboard of a computer or at the periphery of the key 1. The functions of the key 1 are displayed by the device 2. The device 2 displays characters and marks through a matrix type liquid crystal display and also can convert into other optional characters and marks. Thus it is possible to display clearly a state where the key 1 having plural functions is presently working, thereby preventing misoperations of the key 1 and improving the operating efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical field of the invention This invention comprises: 1. This invention relates to the keys of the input device of a combi coater, and relates to an improvement in the method of displaying the functions of the keys.

(,2) Each key on a keyboard often has multiple functions, but in the past, the tlg and function of the key had characters and symbols on the key itself or around it. Line up and fix &7r<
L/te), =. For this reason, in order to become proficient in key operation, more ill training was required than with various types of typewriters with 1 key force and 31 keys.

In addition, conventionally, the characters and symbols displayed on the keys themselves
Jl does not display its function directly, but Et has a combination of several keys - S has a function. Therefore, for those who do not have a considerable amount of prior knowledge about how to operate the keys, the double-row nature of the keys makes them difficult to operate.

The present invention was made in order to reduce this drawback, and it is possible to operate the 1M key function directly by confirming the key function, thereby preventing erroneous operation and improving the 8M operation efficiency. This is the 1st objective.

(3) Structure of "Sending W" The key, which is the computer input device of the present invention, has a liquid crystal variable image device on the surface of the key itself or in the periphery adjacent to the key, and displays the function of the key. Variable image display with liquid crystal (N is a MARIX type liquid crystal display that displays characters and symbols, and a 71-RIS type liquid crystal display that can convert the display to characters and symbols. .

The positional relationship between the key and the variable image device will be explained with reference to the drawings as follows.

B. Figure 1 shows a case where there is a variable image formed by liquid crystal on the surface of the key itself.

2 shows a case where there is a variable image formed by liquid crystal on the upper part adjacent to the keys.

C. FIG. 3 shows a case where there is a variable image formed by liquid crystal on the left side adjacent to the keys.

20 on the left and FIG. 4 show a case where there is a variable image formed by liquid crystal on the upper and right side adjacent to the keys.

E, Figure 5 shows the upper part adjacent to the key, the li part and the right j1
(9 shows the case where there is a variable (rHH image) by the liquid crystal.

(≠) Effects of the invention A, ``& In the keys of the input device of the previous computer, multiple letters and number H8 were fixedly displayed on seven keys with multiple functions, so it was difficult to operate the keys. The only way to check whether the input results are as expected is to use a display other than the keys, such as on the display of the output device; in other words, the means of checking was indirect. In the invention, when the key is pressed, it can be confirmed by a variable image displayed on the surface of the key or around it, and compared to the past, M contact is used as a means of confirming the function of the key. Also, by executing the operation procedure, the operator can confirm whether the key is in the requested state or not, so the 2 display has the check island function of the operation procedure. As a result, erroneous key operations can be prevented and operational efficiency can be improved.

For example, under normal conditions, the functions Δ・B−C and m−p・p
By operating the [Kakudan] key, etc., the display is converted to a key with the functions of Chi, Ko, and So, and the display of [Go] - [E:E; Mouth]. And it's in a good condition.

1-1. A computer with many types of programs,
If you consider using a name that does not have enough /317ii'j for a program, the key operation 111f
For i +, Ili? 1774 It is important to minimize the number of combinations of characters and symbols that cannot be easily deduced from their meanings and have seven functions as long as possible. JL-
I believe that this is better from the point of view of improving the reed production FJ8 series, and the present invention meets this claim.

For example, when using a Kosipiko-ku with seven computers like Pono Computer, which has many programs, you can create a program so that by calling each program, keys with corresponding functions and displays can be created. As a result, the operability of the cosipicoter will be improved.

Maru! To give an example, by calling a program that has a self-timer R1 for all home appliances, the variable image displayed on the liquid crystal display of each key will display [ffl ・shiru [lonely mother 4 = τ
They are displayed as ``X7 Teka'', ``Kyoto U swamp times'', ``Kuni E door times'', etc.

C. Even within the seven programs, if you create a program so that a certain number of 1M operations will give you a key with each function and the size of the person, you will improve the operability of the computer. However, the present invention meets this need.

For example, in a finance company program, when you call up the asset account, the variable image on the LCD of each key is displayed as σ charm.
・ m ・ m etc. will be displayed, and by operating the key of 口ID1, current account 5 funds will be input, and at the same time, the variable image displayed on the LCD of each key will indicate the next input item power. , m, etc.).
