Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an input canister display method in a display device.

[Prior art and its problems]

When inputting data to personal computers, office computers, etc., it is impossible to predict whether input up to the largest digit is possible or not, so errors often occur when the maximum input digit range is exceeded. For example, as shown in Figure 1, enter r1234J as the "Shohin code",
Even after entering a certain number, an alarm message indicating an error may be displayed. Also, as shown in Figure 2,
There are some devices that display an inverted data entry area on the screen with a length corresponding to the number of digits, but even if the maximum number of digits to be input can be roughly guessed, it cannot be recognized at a glance. However, it had the disadvantage of causing errors in operation.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide an input digit display method in a display device that can reliably prevent over-input by clearly indicating the maximum number of input digits on the display screen. With the goal.

[Embodiments of the invention]

In FIG. 3, 11 is data RA)J, into which display data sent from the CPU (not shown) is written. The display data stored in this data RAIJJZ is read out to the latch circuit 12, and is read out to the character generator 13.
is converted into character pattern data. Then, the character pattern data output from the character generator I3 is converted into direct data via the p-s (parallel-serial) conversion circuit 14, and the exclusive logic first'' circuit (
The signal is sent to a CRTfi display section (not shown) via I5 (hereinafter abbreviated as EX-OR circuit) and an intensifier 16. Also,
17 is a control RAM in which control data sent from the C'PU is stored. The control data stored in the control RAM 17 is read out to the latch circuit I8. The data latched by the latch circuit 18 has, for example, an 8-bit configuration and is sent to each circuit as a control signal, and the 7th bit signal is input to the Ex-OR circuit 15. This gx OR circuit 1
5, according to the control signal from the latch circuit 18, the data from the two-control P-8 circuit 14 is sent as it is.
Output is inverted. The output of this EX-OR circuit 15 is then sent to qR via the amplifier 16 as described above.
The signal is sent to the T display section.

Next, the operation of the above example A will be explained. First, the user program is compiled and stored in the main memory (not shown), and the display data is transferred to the data RAM by the CPU.
ZJ and Control Cheetaka Control R
AuzyKtJ is included. An example of the above user program is shown below.

%DATA INDATA: DR (128) CODg: DS Z (4) os c (124) B-P-K: o s z (2)? CNT L KOPgN In the above program, the first r % DATAJ indicates that the data will be defined by the subsequent program. For example, it is defined that the data is constituted by an area of r128J, and consists of ``4'' numerical values and characters of r124J. After finishing the above definition, [CH PROCEDURE J
indicates that the contents below are specific program instructions. In this program instruction,
"rINPUT C0D8 %4" indicates that the maximum number of input digits for the "Shouhin code" is 4 digits.

In FIG. 3, the display data stored in the data RAM 11 is read out to the latch circuit 12 and converted into character pattern data by the character generator 13. The character pattern data output from the character generator 13 is converted into serial data via the P-8 conversion circuit 14 and input to the EX-OR circuit 15. In this case, if the display data indicates energization, the control signal inputted from the control RAM Z7 to the gx OR circuit I5 via the latch circuit 18 is 01. Therefore, P-8 conversion circuit 1
The display data input from GX OR circuit 15 to GX OR circuit 15 is output as is from GX OR circuit 15, and is sent to the CRT display section via amplifier 16, where it is displayed, for example, as shown in FIG. 4(a). Figure 4(a) shows the display state of the character "A", which is displayed in 1 character area 2.
1 is displayed in a character display area 22 configured within 1. The one character area 21 is, for example, 11×13 dots,
The character display area 22 has a configuration of 7×9 dots.

However, when inputting a "Shohin code", the maximum number of digits to be input is rINPU as described above.
T CoDE %4", that is, "The maximum number of digits to input for the Shouhin code is 4 digits.

”, data 5 indicating a data entry box is written in data RAu11, and data indicating a space is written for 4 digits in data RAu11.
A data inversion instruction of 1 is placed in AIJZ7. If the display data is a space, all the line tallies of the character pattern output from the character generator 13 are wO',
The signal is sent to the EX-OR circuit 15 via the P-8 conversion circuit 14. At this time, the inversion instruction rO1000000J is read out from the control RAM 17 to the latch circuit 18, and the I1'' signal is input to the EX OR circuit 15. Therefore, the space data'' is input to the EX OR circuit I5.
All 01's are inverted to 11'' information, sent to the CRT display section via the amplifier 16, and 7x as shown in FIG. 4(b).
The 9-dot character display area 22 is displayed in reverse as an input area or data entry area 23. This j,
When i is %, four data entry areas 23a to 23d are displayed on the CRT display section as shown in FIG. 5, indicating that the maximum number of digits of the input code is 4 digits τ.

In the above embodiment, the space data is inverted with the bits of the control data, but the data entry area may be displayed by providing in advance a turn that avoids inversion.

Further, in the above embodiment, the data entry area is displayed by inverting the entire character display area 22, but the display shape of the data entry area is changed according to the embodiment [11].
The display shape is not limited to 'lJ', and the display shape may be arbitrary as shown in FIGS. 6 to 8, for example, as long as it displays the number of digits in the data entry area.

〔Effect of the invention〕

As described above, according to the present invention, the same number of data entry areas as the pre-specified number of input digits are displayed at predetermined intervals, so the maximum number of input digits can be easily set using the displayed data entry areas. It is possible to provide a method for displaying input signals in a display device that can be used to accurately prevent over-input.
