Abstract

PURPOSE:To decrease the input mistakes and to improve the operability of a keyboard by displaying with lighting only the character corresponding to the operation of a shift key among those characters printed to each character key. CONSTITUTION:A key group 2 set on a keyboard 1 is connected to a transmission part 4 via a keyboard control part 3. At the same time, a shift key storage part 5 is connected to the key group 2 and then to the part 3. In addition, a lighting part 6 is connected to the part 5 to display with lighting only a character part to be inputted among those character keys where plural characters are printed in accordance with the state of a pushed shift key. The signal of the part 6 is sent to the group 2. Therefore an LED that can specify only the corresponding character part is turned on with push of the shift key. As a result, a specific character to be inputted is immediately decided. Then the input mistakes are greatly decreased and the operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard used in various information processing devices such as personal computers and word processors.

[Conventional technology]

Conventionally, in keyboards used in various information processing devices such as personal computers and word processors, multiple characters are printed on one key so that a large number of characters can be entered with a limited number of keys. has been
The system is configured such that one character is selected from the plurality of characters by pressing the shift key and inputted.

[Problem to be solved by the invention]

However, in the conventional keyboard as described above, a plurality of characters are simply printed on one key, and it is not possible to immediately confirm which character will be input just by looking at the key.

As a result, even if there is a mistouch, it is difficult to notice, and input errors are more likely to occur.

The purpose of the present invention is to solve such drawbacks and to make it possible to clearly indicate the character on the key corresponding to the pressed shift key.
Our goal is to provide a keyboard with excellent operability.

[Means to solve the problem]

The present invention provides a key fob configured to output a desired character from a plurality of characters printed on each character key by operating a shift key, comprising: a shift key storage section that stores the operating state of the shift key; , and a lighting section that is connected to the shift key storage section and lights up only the characters corresponding to the operated shift key.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

Note that FIG. 1 is a block diagram showing one embodiment of the keyboard of the present invention, FIG. 2 (A) is a plan view showing a general keyboard, and FIG. 2 (B) is an example of character keys in the keyboard. 3(A) is a perspective view of a character key to which the present invention is applied, and FIG. 3(B) is a perspective view showing a partition plate disposed inside the character key.

In this embodiment, as shown in the block diagram of FIG. 1, a group of keys 2 arranged on a keyboard 1 is connected to a transmitter 4 via a keyboard controller 3,
A shift key storage section 5 is connected to the shift key storage section 5, and this shift key storage section 5 is connected to the keyboard control section 3. Further, in the shift key storage section 5, among the character keys on which a plurality of characters are printed according to the state of the pressed shift key,
A lighting section 6 that can illuminate and display only the manually inputted character portion is connected, and the signal is output to the key group 2.

Further, specific examples thereof are shown in FIGS. 2 and 3.

That is, as shown in FIG. 2(B), a plurality of characters 12a to 12d are printed on a certain character key 11 in the keyboard 10 shown in FIG. 2(A). For keys with multiple characters printed like this, the keys shown in Figure 3 (A
) As shown in FIG.
d is arranged, and in order to prevent light from leaking into adjacent characters, a partition plate 14 as shown in FIG. 3(B) is installed.
is provided.

In the keyboard of this embodiment configured in this way,
When the shift key is pressed, a light emitting diode that can clearly indicate only the corresponding character part is lit, so it can be immediately determined which character is to be input, and input errors are greatly reduced.

Note that the present invention is not limited to the above-described embodiments, and the lighting section may be any device that can light up and display a plurality of characters printed on a character key in accordance with the operating state of the shift key.

〔Effect of the invention〕

As described above, according to the present invention, among the plurality of characters printed on each character key, only the character corresponding to the operation of the shift key can be illuminated, so input errors can be significantly reduced. Improves operability.
