Abstract

PURPOSE:To ensure the simple change of arrangement of keys on a keyboard by displaying the characters and symbols allocated to keys at the display part of each key based on the key arrangement data recorded on a recording medium. CONSTITUTION:The key arrangement data read out of a recording medium by a memory 13 is written into a key arrangement memory part 12 which stores the state of the key arrangement used presently. Then a liquid crystal display part 11 reads the data displayed on a liquid crystal key 2 of a keyboard 1 out of the part 12. This read-out data is displayed at a display part (liquid crystal plate) of the key 2. Thus a prescribed character or symbol is allocated to each key on the keyboard 1. When the display characters of keys are changed, a conversion key (not shown here) and the keys to be converted are pushed on the keyboard 1. Thus the display character of the relevant key is converted into another display character.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard device used in an information processing device. [Prior Art] Conventional keyboard devices used in information processing devices are configured to provide the key layout required by the user to a JIS standard kana layout compliant keyboard layout, a kana 50-syllabary keyboard layout, or an English JIS keyboard layout.
The configuration is such that the keyboard device is selected from among keyboard devices having a key arrangement such as an IS key arrangement.

[Problem that the invention seeks to solve]

The conventional keyboard device as described above has the disadvantage that when changing the type of key arrangement on the keyboard, the keyboard device must be replaced.

In addition, because multiple letters, numbers, and symbols are displayed corresponding to one key, it is difficult for the user to see unnecessary letters, numbers, and symbols. There are also problems.

An object of the present invention is to eliminate the drawbacks of the conventional keyboard device as described above, and to provide a keyboard that does not require replacing the keyboard device when changing the type of key arrangement, has excellent operability, and has an easy-to-read display. The goal is to provide equipment.

[Means for solving problems]

The keyboard device of the present invention has the following features for each key on the keyboard:
In order to have the ability to assign arbitrary characters and symbols,
A memory is provided in the keyboard to store the contents of the key arrangement, and a display board with a variable display function such as a liquid crystal board is provided in the display section of each key to display the contents of the memory on the display board. It is configured so that it can be changed and has a function that allows the memory contents to be registered in a storage medium such as a card.

That is, the keyboard device of the present invention includes a storage device that reads desired key layout data from a storage medium that stores the desired key layout data, a key layout storage section that stores the data read by the storage device, and a keyboard that stores the key layout data. a display control unit that controls display operations of the keyboard layout data stored in a storage unit; a keyboard layout control unit that controls operations of the storage device, the keyboard layout storage unit, and the display control unit; The character key includes a character key having a variable display portion that changes the displayed character under the control of a control portion, and a control key having a conversion key that instructs conversion of the displayed character of the character key.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

1A and 1B are a plan view and a side view showing an embodiment of the present invention, and FIG. 2 is an enlarged perspective view of section A in FIG. 1.

As shown in FIGS. 1 and 2, the keyboard 1 has a liquid crystal key 2 and a control key 3, and is configured to allow a storage medium 4 to be inserted and removed.

FIG. 3 is a block diagram showing the internal configuration of the embodiment of FIG. 1. Inside the keyboard 1, there is a key layout control section 10.
, a key arrangement storage section 12 , a liquid crystal display control section 11 , and a storage device 13 . Key layout control section 1
0 controls changing the key arrangement and controls the LCD display control unit 1.
1, the key layout storage section 12, and the storage device 13. The keyboard layout storage unit 12 stores the state of the currently used keyboard layout. The liquid crystal display control section 11 reads data to be displayed on the liquid crystal keys 2 from the key arrangement storage section 12, transmits the data to the display section of the liquid crystal keys 2, and displays the data. The storage device 10 reads the keyboard layout data from the storage medium 4 and stores it in the keyboard layout storage section 12.
Write to.

Next, a method of changing the key layout in the keyboard device constructed as described above will be explained with reference to FIG.

FIG. 4 is an explanatory diagram showing an example of a method for changing the key arrangement. FIG. 4 shows an example in which a key displayed as "A" is changed to "B". The upper part of FIG. 4 shows the procedure of the conversion operation, and the lower part shows the display state of the keys during the operation shown in the upper part. That is, control key 3 (see Figure 1)
Press the "Convert" key provided inside. At this time, the key display remains "A". Next, the key you want to convert "
When you press "A", the key display flashes "A". When the last converted key "B" is pressed, the key display changes to "FB" and the conversion operation ends.

〔Effect of the invention〕

As explained above, the present invention has the effect that the user can easily change the key arrangement on the keyboard at any time as necessary, and since the key display is displayed on the liquid crystal, unnecessary displays can be avoided. Since it is possible to display only the necessary information, it has the effect of improving visibility and operability.
