Abstract

PURPOSE:To attain an easy-to-see display and facilitation of an operation by variably displaying characters, symbols and numerics, all of which are previously assigned in terms of display, on a variable display part in accordance with a display output. CONSTITUTION:When a command analysis part 2 discriminates that output signals from a depression key 1 is ones from shift keys 82-86, a shift key processing part 4 reads out shift-state data corresponding to the output signal from a shift key definition memory 6, and sets it in a shift stage setting memory 8. In this case, if only the shift key 85 is depressed, each liquid crystal display 12 displays KANA (Japanese syllabary) one by one in an array the same as the key array of KANA. Such a KANA array pattern is not modified unless shift keys other than the shift key 85 are depressed, and each liquid crystal display 12 continues the display as it is. Thus characters, symbols and numerics displayed on a data key can be made more visible.

When the display is displayed, letters, symbols, and numbers to which display has been individually assigned in advance are variably displayed one by one in accordance with the display output.

〔Example〕

Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a block diagram showing the configuration of an information input device according to an embodiment of the invention, and Fig. 2 is a block diagram showing the configuration of an information input device according to an embodiment of the invention. Diagram showing the arrangement of various keys, 3rd
This figure is a perspective view showing the configuration of a data key among the various keys shown in FIG. 2.

In FIG. 1, 1 is a pressed key, and the pressed key 1
2 shows data keys representing alphanumeric characters, kana, and symbols shown in FIGS. 32 to 81, and shift keys for specifying the shift states of the data keys 32 to 81 shown in FIGS. 82 to 86. The input side of the command analysis section 2 is connected to the push key 1 and the command analysis memory 5, respectively. The command analysis section 2 analyzes the signal output from the press key 1 when the press key 1 is pressed, using data stored in the command analysis memory 5, and determines whether the pressed key 1 is a data key 32. ~81 or shift key 82~
It is determined whether it was 86 or not.

The data key processing section 3 is driven by a signal indicating that the data keys 32 to 81 have been pressed from the command analysis section 2, and is driven by the code conversion definition memory 7.
, the signal is converted and outputted based on the data stored in the shift state data storage means, that is, the shift state setting memory 8, respectively. The shift key processing unit 4 receives shift keys 82 to 8 from the command analysis unit 2.
6 is pressed and a signal indicating the next is given, the signal is analyzed based on the data stored in the shift key definition memory 6, and a shift state corresponding to the signal is set and output. It has become. The command analysis memory 5 uses a ROM, for example, and stores a plurality of input signal patterns for analyzing signals input from the data keys 32-81.

The shift key definition memory 6 uses, for example, a ROM, and stores shift state data for defining shift shapes corresponding to signals inputted from the shift keys 82 to 86. For example, a ROM is used as the code conversion definition memory 7, and the data keys 32 to 8 are
A code for code conversion according to the shift state of the input signal is stored. The shift state setting memory 8 uses, for example, a RAM, and stores the shift state data set by the shift key processing section 4 and outputs the shift state data in response to memory access from the data key processing section 3. is configured to do so. For example, a ROM is used as the array pattern storage means, that is, the data key display memory 10, and variable display portions are provided on the data keys 32 to 81, respectively, depending on the shift state of the signals input from the data keys 32 to 81. That is, a plurality of arrangement patterns of characters and the like to be displayed on the liquid crystal display 12 are stored. The arrangement pattern selection means, that is, the data key display section 11 uses the shift key processing section 4 to select the shift state setting memory 8.
Every time the shift state data set in
2 to 81K liquid crystal display 1 provided respectively
Display output to 2. The liquid crystal display 12 is disposed above each of the data keys 32 to 81 as described above (see FIG. is configured to display one character or symbol at a time. Note that 9 is an interface between the information human power device and other devices.

Next, the operation of the information manpower device having the above-described configuration will be explained.

When the operator presses the press key 1 and a predetermined signal is given from the press key 1 to the command analysis section 2, the signal is combined with a plurality of signal patterns stored in the command analysis memory 5 in the command analysis section 2. The data keys 32 to 81 are selected based on the signal pattern that matches the signal extracted from the command analysis memory 5.
It is determined whether the output signal is from the shift keys 82 to 86 or from the shift keys 82 to 86. The signal is applied to data keys 32-8
1, the data key processing section 3 converts the code corresponding to the shift state of the output signal to the code conversion definition memory 7, and converts the shift state data corresponding to the shift state of the output signal from the code conversion definition memory 7. They are respectively read out from the shift state setting memory 8 and output to the interface 9.

On the other hand, when the command analysis section 2 determines that the output signal from the pressed key 1 is an output signal from the shift keys 82 to 86, the shift key processing section 4 converts the shift state data corresponding to the output signal into It will be read from the shift key definition memory 6 and set in the shift state setting memory 8. In this case, for example, if only the shift key 85 is pressed, each liquid crystal display 12 will display one kana character in an arrangement similar to the conventional key arrangement for kana characters, as shown in FIG. 2a. There are so many things to do. The arrangement pattern of kana characters as shown in FIG.
2 continues the display. However, when the shift key processing section 4 recognizes that the shift key 86 as well as the shift key 85 have been pressed down completely by the operator, the shift state data corresponding to the output signals from these shift keys 85 and 86 are used by the nuclear shift key processing section 4 to define shift keys. It is read out from the memory 6, output to the shift state setting memory 8, and updated and stored in the shift state setting memory 8. When the shift state data read from the shift key definition memory 6 by the shift key processing section 4 is given to the data key display section 11, the arrangement pattern of kana characters corresponding to the shift state data is displayed as a data key by the data key display section 11. The data is read out from the display memory 10 and displayed on each of the liquid crystal displays 12. As a result, a unique arrangement pattern of kana characters (in alphabetical order) as illustrated in No. 25''Jb is displayed on each of the liquid crystal displays 12, and the display remains as it is unless the shift keys 82 to 86 are pressed again. This will be continued by each of the liquid crystal displays 12.

〔Effect of the invention〕

As described above, according to the present invention, when shift state data is updated, there is an arrangement of i characters, symbols, and numbers in the character group, symbol group, and number group constituting the information corresponding to the data. In addition to selecting a pattern and outputting it for display, characters, symbols, and numbers that have been individually assigned to be displayed in advance are variably displayed one by one according to the display output, so that the characters displayed on the data keys, This has the effect of making symbols, numbers, etc. easier to see and providing an information input device that is easy to operate even for unskilled people.
