Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display control method for an input item area of a display attached to a data input terminal device.

Data input devices such as keyboards are equipped with a display to display input data for the purpose of preventing errors in input data, and the format of the display is usually a 5 x 7 or 7 x 9 dot type. be. Furthermore, when input data is displayed, it is common to use a cursor to indicate the next data input position. FIG. 1 shows an example of this, where 10 is the screen of a CRT display, ABC, etc. are characters displayed on the screen. A cursor 12 indicates the next character input position.

The cursor 12 shifts one step to the right each time one character is input or the space key is pressed, and when one line is completed, it jumps to the next line. This cursor 12 is normally displayed in a so-called cursor-only area below the character display area. Figure 2 shows another display example. In this case, the next character input position is left blank, and then the next character input position displays N if the position is scheduled for inputting numbers, and B if it is planned to be left blank. do. However, this method has drawbacks such as being difficult to see and confusing. In the present invention, a cursor is displayed using dots used for displaying characters, the next character input position is indicated by a dot, and the boundaries between one field (one word or one item) are indicated by a dot group. It is characterized by 0, which is indicated by a mark.

In this way, dots for the cursor are not required, so the dots on the display can be used effectively, and miniaturization becomes possible. Also, the cursor is familiar to this type of display, and since the number of dots and lines is small, it is not too obtrusive. Furthermore, since the next character position and field delimiter can be determined, it is easy to see which part of the slip is currently being input, which has the advantage of facilitating accurate data input. Next, this will be further explained in detail with reference to examples. FIG. 3 shows a display example using the display control method of the present invention.

"SA", "SI", and "SU" are characters that have already been input, and 12 is a force-sol indicating the next character input position. This display 20 is 5×
It is a 7-dot type, and the cursor 12 uses five dots for one horizontal row. Cursor 1 when the next character is entered
2 disappears, the next character is displayed in its place, and Force-Sol is displayed in a position moved one place to the right. 14 is one of the dots for displaying characters, specifically, the one dot in the center of the bottom line, which indicates the character input position of next next, next next next, . . . .

16 is a hanging mark indicating the end of one field, consisting of three dots from the right end of the bottom row and three dots from the bottom of the right column.

18 is a blank area, and nothing is displayed in this area.

FIG. 4 shows a data input terminal device equipped with the display of FIG. This terminal device is connected to the Mikawa telephone line and inputs slip data, and is equipped with a keyboard 22, a printer 24, and the like. FIG. 5 shows an example of a slip in which data is input using the terminal device 30 shown in FIG. This slip 2 consists of a header part 4, a body part 6, and a tail part 8. An example of the display on the display 20, taking the data input operation for the slip 2 as an example, is as follows. First, on the keyboard 22, press “
Press the "Select" key and then press the number "1" key. When you press the "Select" key, the character "Select" will appear on the display; then, when you press the number "1" key, the display will show The character Hizuke appears. At this time, the printer 24 prints *Hatch You*Select 1. This means that the format check program for type 1 slips, that is, the slips in the format shown in FIG. 5, has been selected. Next 54
I keyed in the date 1017, but the first "5"
When the key is pressed, the display 20 shows 5-, ``,'', .
,,"""001 is displayed. Next number 4, 1...
As ``...'' is input, the number is displayed, the cursor moves, and when the data 54107 has been input, the display shows 541017...''''
It becomes 001. Next, when you press the "Space" key, "Tempo Code" appears on the display, and when you press the "FI" function key, in which you have previously registered the store code, the store code written on the slip will appear on the display. 5 with date
4101701295''001. next"
When you press ``Space'', ``Shozaikubun'' appears on the display, and when you press ``0'', which usually means 1, the display becomes 541017012950''001. next"
When you press "Space", the display becomes "Akakurokupun", and when you press "0", which means "black", the display becomes 54.
10170129500 001, and one line is full. In this case, the header part of the slip is treated as one line. Next, press "Space" and "Memory input", the display will show the Himban code, and the printer will be 5410170129.
500 are printed and these data are written to the transmit memory. Next, when you enter the product number code ``13903'', the display will show 1390 pieces,...''002, and then when you press ``Space'', the display will read ``SUURYO'', and then ``
When 201 is input, the display becomes 1390320002. This completes the line in the body section, so next click "Space"
When "memory input" is pressed, the display becomes the Himban code, the printer prints i390320002, and these data are written to the transmission memory. Next, the next product number code is input, the quantity is input, and "base" and "memory input" are pressed, and the same process is repeated. The above processing is mainly performed by software, but if it is explained in terms of hardware, it will be as shown in FIG. 6.

In this figure, 32 is a memory for a line format check program, and in this memory are registered parameters indicating the characteristics of each line of the slip, such as whether the relevant digit is a number, kana, or blank. 34 is a special code generating circuit that generates the dots, pots, etc., 36 is a character generator, and 38 is a display pattern register.

A step-up counter 42 operates in response to data input from the keyboard 22, and provides a read address to the memory 32 every time a row changes (one row is treated as two rows). As a result, one line of the format check program is extracted from the memory and stored in the register 44'. Reference numeral 46 denotes an input field discrimination circuit which separates the parameters in the register 44 into fields and outputs an open signal for the gate 48 for each field.

Also, the special code generation circuit 34 is activated to output a special code pattern signal. This pattern signal is supplied to the display pattern register 38, and on the other hand, a character pattern signal generated by the character generator 36 based on the character code signal inputted from the keyboard 22 is also inputted to this register 38, and the register 38 of the display control unit Mako 4kawa The contents of are displayed on the display 20. 42 is a cursor control unit;
Each time a character is inputted on the keyboard 22, the cursor address is advanced and the cursor is written into the display pattern register 38.

When the input for one line is completed, the step-up counter 42 gives the next starting address to the memory 32, and causes the next line format check program to start.

The same applies below. As explained in detail above, according to the present invention, character display dots are used to display the cursor, the next and subsequent character input positions, and field separation, so the display area can be used effectively. , and the next and subsequent data input instructions are also displayed, making it easier to determine the position of the character currently being input, and ensuring accurate data input.
