Abstract

PURPOSE:To input a character by a small number of keys such as a cursor key, a selecting key and a shift key, by displaying a keyboard on an indicator so that an input character can be selected by moving a cursor. CONSTITUTION:A controlling circuit is set to a read-out mode first, and an alphabet keyboard 13 and a mode symbol READ 15 are displayed. For instance, in case of inputting 'S', a cursor key 22 is operated two times so that a cursor being in a position of 'A' in the initial state is moved to a position of 'S'. It is detected by the controlling circuit that the cursor key 22 is operated, and '11' is added and calculated to a code of the present cursor. As a result of said addition of two times, the code becomes '22', it is decided to be 'S' from a code table, and the cursor being under 'S' is lighted. In such a state, by operating a selecting key 24, 'S' is displayed on a display part 11.

Overall control is performed by exchanging data with each section, which will be described later, via a signal bus +31 according to a program in a program memory 121 in which a processing program is stored in advance. 14) is a keyboard consisting of various keys, key signals are input to the control circuit +11 through the input buffer circuit +51t, and the control circuit 111 that has taken in the key signals stores the processing operations corresponding to the middle signals in a 10-gram memory. Follow the +27 program. keyboard +43
As shown in Fig. g3, it is composed of keys for calculation and keys for reading and writing data, the details of which will be described later.

(6; is a calculation memory that stores calculation results etc. in the calculation mode, and writing and reading are controlled by the 1vlJ control circuit +11. (7) is a memory that stores memo data such as names and telephone numbers. In this case, it is configured as shown in Fig. 4 to store a maximum of 12 characters and 12 digit numbers in one item as a pair, and has a storage capacity of 100 items in total, and the data can be read out by the control circuit +11. and writing is controlled.

The character data is stored in the memory (7) as a code of the character generator (8), and when reading and displaying the data stored in the memory (7), the control circuit 11+ is stored in the memory (7). It is configured to drive a character generator (8) based on the code, generate a corresponding character pattern, supply it to the display drive circuit (91), and display the character on the display 111j.The display 6 is a liquid crystal display. As shown in FIG. 2, the first display section (ill) is provided with a 12-digit 5 x 7 dot matrix and displays characters.

A 12-digit Japanese character segment is provided to display the numerical value @2
The display part (12+) and the third display part a3 which displays an alphabet or kana keyboard, the third display part a3
1 is a cursor segment that further displays the cursor position)
tL4J'14J . . . is formed below the letters in both kana and Japanese alphabets, and a mode display segment α9 4 is provided at the right end to indicate the mode state.

The detection of the cursor position is performed in such a way that the control circuit +l+ calculates and determines the cursor position based on the code table stored in the program memo 21, as shown in Figure 5. The hour code is "0"
, and the cursor is set at the "A" and rAJ positions.

Next, the operation of the present invention having such a configuration will be explained.

First, when you operate the 'w [ON key (In), the control circuit Ill
is set to the initial reading mode, and displays the alphabet keyboard of the third display section α3 and the mode symbol rFtEADJα9, as shown in FIG. a9. At this time, the code indicating the cursor position is set to rOJ, and when a display signal is supplied to the display drive circuit +91 to light up the "AJ" indicated by the code rOJ based on the code table in FIG. Cursor α4 is displayed under rAJ.If this data is not stored in memory at this time and you want to input it and store it, operate mode key σ9 on the keyboard (4) in the display state shown in Fig. 9. The control circuit (11) that detected the mode key signal sets the memory (71) to the writing state and also sets the 1 display (10@3 display unit 13) to the writing state.
The mode symbol or wa I Tg J (11! 10 is displayed as shown in figure. So, for example, enter the name and phone number of 3xtti as rsANX% 06-991-1181
The case where J is input will be explained.

First, operate the cursor key twice to move the cursor from the rAJ position to the "S" position in order to input rs,,H-. When the control circuit 111 detects that the cursor key (2) has been operated, it calculates rllJ by 7FO on the code of the current cursor, as shown in the flowchart of FIG. 8, to obtain the code each time it detects the operation. The cursor is now r
Since the code at the AJ position is "0", the code as a result of operating the cursor key twice is "22", and the control circuit 111 determines that it is "S" from the code table and moves it to the "S" position. A display signal that lights up the cursor is output to the display drive circuit (91. This lights up the cursor under "S". Then, when the selection key c! 41'fl is operated to manually control the The circuit Il+ reads out the data of SJ from the code table and reads the control circuit (
At the same time as storing it in the register in I2, the character pattern of "S" is read out from the character generator (8) and supplied to the display drive circuit (9). "S" will be displayed as shown in FIG. You can input r S A NX, X J like this.

At this time, the 11118 circuit +IJ is set to +1 by operating the cursor key Q1 as shown in FIG. By operating the cursor keys -
1. Also, by operating the cursor key @, a calculation of -11 is performed to detect the cursor position.

Next, enter the name as described above and use ζRoll.

In order to enter a telephone number on the second display section (13) of display device a1, press the cursor movement key (111uz) on the first and second display sections (111uz).
To) When you operate the up/down movement key ■ among the four ■, the lower segment (d segment) of the leftmost digit lights up on the second display section tl'1Jf), instructing you to move the cursor.Then, enter the phone number. If you input "r06-991-1181" on the keyboard (using the numeric keypad ■ and the minus key on 41), it will be displayed on the @2 display section σ2 as shown in Figure 16.In this way, you can complete the data input and write it to your friend. , when the input key (to) is operated to store it in the memo month 7), the friend data stored in the register in the MJ control circuit 1H is transferred to the memory (7) and stored.At this time, the control circuit +13 searches the empty memory area 1R and stores it in the empty area.From now on, the same memory area (
7) can store 100 items of data.

Note that the input operation described above is for alphabetical input, but if you want to input in kana.

When the shift key 6v of the keyboard +4J is operated, a shift key signal is detected, and the mental control circuit +11 controls the display drive circuit f91 to display a kana keyboard as shown in FIG. 14 in 6 phases of 1 display. The input characters can be selected in the same way as described above by moving the cursor and operating the 9th selection key @. It can be stored on January 71st.

The keyboard is controlled so that the alphabet and kana keyboards are displayed alternately each time the shift key 13υ is operated, and it is also possible to input mixed letters of the alphabet and kana by selecting arbitrarily. At this time, the cursor I is configured so that it lights up in common for a pair of kana and alphabet.
We are trying to reduce the number of signal terminals that control the lighting of the cursor.

Next, the operation of reading and displaying the data stored in the memo (January 7) will be explained.

In this case, switch to the read mode by operating the mode gill recess. The mode is configured such that read, write, and calculation modes are cyclically switched each time the mode key α3 is operated. As shown in Figure 9, the MJ control circuit detected the output key signal when the output key (to) was operated after switching to the read state (IJFi, Memo January 7)
Search alphabetically among the data stored in the , for example, if there is an item in which data starting with rAJ is stored, it is read out, and based on the nine character code read out, a character generator (Fl t' is driven and one display is performed). vessel(
The name is displayed on the @1 display section aυ of III, and the telephone number is displayed on the II2 display section σ2. In this case, an alphabet keyboard is not necessary.

The third display section α3 is turned off. Each time you operate the output key (33), it is read out sequentially from Memo +7 to +71 and displayed on the display aO. When you operate the output key C32 to read out sequentially, the data whose initial letter is the last letter of the alphabet. Since it takes a very long time to read out a search result, it is also possible to search by inputting a single initial letter.

Example, ttfli human power L7trsANXX 06-99
1-1131J), with the alphabet keyboard shown in Figure 9 displayed, operate the 2 cursor keys (to) (211) (c) to move the cursor to the "-8" position. After that, operate the selection key @ and input "S" to display it on the first display part (ill) of the display q■.

Then, when you operate the output key (to), the control circuit (11
searches for data starting with the input "S" and displays it. If the displayed data is not what you want, you can change it by operating the output keys c32 in sequence.

Data starting with “S” will be displayed, and the desired one is number 16.
When the screen shown in the figure is displayed, stop operating the output key G3. In this way, the data stored in the memory (7) can be read and displayed as desired.

Next, a case in which calculation is performed will be explained.

In this case, first, when switching to the calculation mode using the mode key σ], rOJ is displayed on the rightmost digit of the second display part f121 of the display +tU, as shown in FIG. only to be
The alphabet keyboard of the third display section +13 is unnecessary and is turned off. This state is the same as that of a normal electronic desktop calculator, and calculations can be performed using the numeric keypad (support) of the keyboard (4) and the calculation key Op. The control circuit tl+ performs the calculation while exchanging data with the calculation memory (6), and displays the calculation result t- on the second display section ff3. In addition, when the memory key Q1G is operated to store the calculation result, it is stored in a predetermined area of the calculation memory (6) and at the same time, the memory contents are displayed on the first display section 111 as shown in FIG. .

Although the embodiment has been described with respect to an electronic desktop calculator with a memo function, it is also applicable to electronic devices that require input of one character.

(G) Effects of the Invention As described above, the character data input device of the present invention displays a keyboard showing input characters on one display.

By configuring the input character to be selected by moving the cursor, it is highly effective when applied to portable electronic devices where the keys for character input are a small number of keys, the cursor-1 selection key and the shift key. .

Furthermore, by using the cursor for both kana and alphabet display, the number of lighting terminals of the cursor is reduced and the structure is simplified, which has an extremely practical effect.
