Abstract

PURPOSE:To decide the present set mode and to facilitate the easy display of contents of each switch by displaying just one of mode-set characters, symbols, patterns, etc. on the surface of a keyboard switch. CONSTITUTION:In an initial action mode a mode of a high using frequency is previously selected and displayed on the surface of a keyboard switch 10. For instance, a symbol '3' displayed on the keyboard surface is delivered from a keyboard with push of the switch 10. Then another display is displayed with push of a mode changeover switch 11 and 'A' (KATAKANA, Japanese syllabary) is delivered from the keyboard with the second push of the switch 10. Thus both symbols '3' and 'A' are outputted from the keyboard with operations of the switch 11 and the switch 10. In such a way, just one of mode- set characters, symbols, etc. is displayed via switches 10 and 11 to know the present set mode and also to facilitate the easy display of contents of each switch.

Description

[Detailed description of the invention] 3 Detailed explanation of the invention [Industrial application field] The present invention relates to a method for displaying keyboard switches.

[Conventional technology]

First, characters, symbols, patterns, etc. corresponding to the switches were printed on the surfaces of multiple switches.

[Problem that the invention seeks to solve]

With conventional printing on the switch surface, there are many types of characters, symbols, patterns, etc. on one switch surface, making it difficult to see <<,
Moreover, since the space is narrow, printing of three to four types is the limit, and it is difficult to display three or more types of roles.

Furthermore, the graphic display is not printed, and the correspondence between the patterns and the switches is unclear. Another drawback is that the switch has multiple displays, making it difficult to tell which mode it is currently set to.

[Means for solving problems]

In the keyboard switch of the present invention, when one switch is selected from the outside, the selected character, symbol,
[Embodiment] An embodiment of the keyboard switch of the present invention will be described below based on the drawings. In FIG. 1, a transparent protection plate 1.6 x 8 rows of liquid crystal displays 2. Conductive rubber 31 LCD driver work on the circuit board 04. Afternoon
A ROM C5 storing characters, symbols, patterns, etc. corresponding to the switches is provided, and a flat cable 6 is provided for determining the power supply necessary for this key switch and the address of the ROM C. Figure 2 shows the liquid crystal display.
The letter [A] is displayed.

Next, an example of operation will be explained.

FIG. 5 shows the frequently used modes selected in advance and displayed on the keyboard switch surface during the initial operation when the power is turned on. Keyboard switch 10. By pressing , the symbol [3] displayed on the keyboard switch surface is output from the keyboard in the same way as before. Figure 6 shows mode selector switch 1 on the keyboard.
11. Shows the display when you press . By pressing the same keyboard switch 10 as described above, a signal roughly corresponding to the symbol [A] displayed on the keyboard switch surface is output from the keyboard.

As described above, by operating the mode changeover switch, the symbol [:3:
+12. C a: +13. Figure 8, which allows output of c〆:1141(:#]15 from the keyboard, shows that the arrangement of the symbols on the keyboard has been changed, and shows that the keyboard switch can be configured in a number of arrangements. By using RAM C instead of ROM C on the liquid crystal display, the display symbol of the corresponding keyboard switch can be arbitrarily changed from the outside.

FIG. 3 shows another example of the display method. Transparent protection plate on the key switch surface 7. Characters, symbols, and symbols for keys
Figures such as patterns are placed in advance, a portion Bb where panels created using light emitting elements 8α such as EL are overlapped, and a power cable necessary for displaying the selected graphic panel 9. It is something that you have. FIG. 4 shows an example of the shape of the display panel 8α.

〔Effect of the invention〕

As explained above, the present invention provides mode-setting characters and symbols on the surface of a keyboard switch.

By displaying only one pattern, etc., it is possible to know what mode is currently set, and the contents of each switch can be easily seen.

Note that the present invention is more effective when used by unskilled persons.

Claims (1)

[Claims] When one switch is externally selected, only one of the selected characters, symbols, patterns, etc. is displayed on the keyboard switch surface, in a keyboard switch that has multiple roles such as characters, symbols, patterns, etc. A keyboard switch characterized by:
