Description

[Detailed Description of the Invention] The present invention allows multiple different types of input to be performed using one key.
The present invention relates to a keyboard that allows input by operating a shift key.

Conventionally, in the keyboard of an electronic ill calculator,
When one key has multiple different types of input functions (for example, numeric and English alphabets), each key in key group 1 should have multiple displays corresponding to each function, as shown in Part 1. After printing, change the function using shift key 2.

A light emitting element 3 is attached to the shift key 2.

2< so that the light emitting element 3 is turned on or off by operating the shift key 2.

Which function is selected is determined based on whether or not the light emitting element 3 is lit, and the keys are operated accordingly.

However, with this method, the key operation cannot be performed correctly unless the user remembers whether or not the shift key 2 is pressed or looks at the shift key 2 every time. This is an obstacle for the operator to operate the keys quickly and accurately.

SUMMARY OF THE INVENTION An object of the present invention is to provide a keyboard device that eliminates the above-mentioned drawbacks and allows input operations to be performed easily, correctly, and quickly when a shift key is switched.

The present invention will be explained in detail below based on the drawings.

FIG. 2 shows an embodiment of the present invention. Each key has two displays belonging to two function groups, and in this case, the light emitting element 5 is disposed at the position of the display corresponding to the first function (number). The shift key 4 is not provided with a light emitting element.

When shift key 4 is pressed, light emitting element 5 is displayed in the display area of the first function.
is lit to immediately indicate that the first function has been selected. Next, when the shift key 4 is pressed again, the light emitting element 5Vi turns off, indicating that the second function (letter) has been selected. In the explanation up to now, the light emitting element has not been disposed at the display position corresponding to the second function, but it is clear that doing so increases the circuit complexity, but this is not a problem. Further, as the light emitting element 5, a semiconductor diode,
An electroluminescent cell or the like can be selected as appropriate. Further, in some cases, a key for identification may be used not only by one light emission but also by a passive liquid crystal or the like, so although in this embodiment it is used as a light emitting element, it can be broadly referred to as an identification element.

A second embodiment having three functions will be explained with reference to FIG. Press shift key 4 at the beginning.

The light emitting element 5 lights up at the position of the display indicating the number of the first function.
Next, when the shift key 4t is pressed for the second time, the light emitting element 5a at the position where the katakana of the second function is displayed lights up.

The light emitting element 5 is turned off. When the shift key 4 is pressed for the third time, both the light emitting elements 5a and 5 are turned off, and it can be seen just by looking at the key that the third functional alphabet has been selected.

Note that there is no restriction on the number of input function groups from the spirit of the present invention.

As you can see from the above explanation, the keyboard operation name is that when you change the function by operating the shift key, you don't have to remember the number of times you press the shift key, but you can immediately perform the correct key operation by looking at the key itself. Since it is possible to detect whether or not there is a noise, manual key operations can be performed quickly and errors can be reduced.

Claims (1)

[Claims] In a keyboard comprising a group of keys in which input functions are divided into a plurality of groups, each key having a plurality of displays belonging to each input function group, and a shift key for selecting an input function of the group of keys, the key The plurality of displays are provided with identification elements at display positions corresponding to each input function other than at least one input function, and when the shift key is operated, the identification element corresponding to the input function is activated. A keyboard device known as TW.
