Abstract

PURPOSE:To simplify remarkably the input operation of a numeric data by giving a data of numeral '0' to remaining low-order digits to form a numeric data when a data is inputted from an end key before the numeric data with a maximum digit number is not finished for input. CONSTITUTION:When each key of a key matrix 21 is operated selectively, a code data representing a corresponding numeral is fetched in a signal processing circuit 14. When a numeric data to be inputted is subject to key input operation one by one digit from the most significant digit and the end key ENTER is operated before the numeric data with maximum digit number is inputted, the circuit 14 gives numeric '0' data to remaining digits not inputted yet simultaneously to form a numeric data to be displayed and the result is stored in a nonvolatile memory 24. This means that when '0' digits exist in the low order digits of the numeric data, the operation of the key ENTER is enough without operation of 0-key at each digit. Thus, the key operation is simplified in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to an input display device, and is particularly applicable to a data input device for inputting numerical data of a predetermined number of digits manually.

B Summary of the Invention In an input display device configured to input numeric data of the maximum number of digits one by one, when data is input from the end key before the numeric data of the maximum number of digits has been inputted, the remaining numeric data remains. By entering the data of the number "O" in the lower digit, the input operation is simplified.

C Conventional technology DB S (direct-broadcast 5
(atellite) broadcasting is carried out by receivers scattered over a wide area. Broadcast waves arriving from Star H can be directly received by a small parabolic antenna, so one company rents a broadcast band and transmits signals from the center to each station via receivers installed at branches scattered over a wide area. It is being considered that it can be used as a means of transmitting information to branches. In this case, the user can specify any frequency included in the available broadcast band and preset the channel on which information can be transmitted.
Thus, by simultaneously transmitting multiple pieces of information using multiple channels, utilization efficiency can be increased.

In this case, the minimum unit of frequency that can be preset is selected to be a value that maintains a frequency interval that does not cause interference or disturbance between each channel, and the frequency of each channel is specified according to this when presetting the frequency. This will determine the number of digits of frequency that must be used. When presetting the frequency of each channel, it is necessary to input the numerical data of the predetermined number of digits without excess or deficiency.

Problem to be Solved by the Invention By the way, as a means for presetting the frequency of each channel, a channel frequency memory having a memory area for storing the frequency of each channel is prepared in advance in the receiver, and the frequency of each channel is preset by using a numeric keypad, for example. For example, if the frequency band used is 11.700 (GH2) to 12.199 (
GHz), 2 digits above the decimal point and 3 digits below the decimal point.
Numerical data of digits (5 digits in total) must be operated in sequence using the numeric keypad.

In practice, as a key human-powered device, as shown in Figure 3, "0
” to “9” keys and end key rENTE
For example, an input device 1 having RJ, for example rll,
When presetting the frequency of 700J (GHz), (1) - 1"l) - (7) - (Q) - (Q) - C
Selectively operate each key in the order of ENTER).

Such manual key operations have the problem of placing a heavy burden on the operator since each key must be selected accurately, so it is desirable to simplify the operation as much as possible.

The present invention has been made in consideration of the above points, and is intended to simplify the input operation of numerical data as much as possible.

E Means for solving problem When data is input from the end key "rENTER" in the input state, data of the number "0" is entered in the lower (NM) digits to form the numerical data to be input and displayed.

If the end key rENTERJ is operated before inputting the maximum number of digits of numerical data, the signal processing circuit 14
enters the number "0" data into the remaining lower digits to form the numerical data to be input and displayed.

Therefore, it is not necessary to input the numerical data corresponding to the lower digit "0" one by one, thereby simplifying the operation of the input display device.

G example An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, broadcast waves received by an antenna 11 are supplied to an information reproducing circuit 13 of a broadcast wave receiving section 12,
The information reproducing circuit 13 receives the broadcast wave of the channel corresponding to the channel selection signal Sl given from the channel selection circuit 15.

The tuning circuit 15 is controlled for tuning by a tuning command signal S2 generated in a signal processing circuit 14 having a microcomputer configuration, for example, and sends out a tuning signal S1 corresponding to the tuning command signal S2.

The signal processing circuit 14 includes, as described above with reference to FIG.
Numeric keypad with keys “0” to “9” and end key rE
A key matrix 21 including an input device 1 having NTERJ is connected, and when each key of the key matrix 21 is selectively operated, code data representing a corresponding number is taken into the signal processing circuit 14.

In this embodiment, the signal processing circuit 14 terminates the data input operation by inputting numerical data using the numeric keypad and then pressing the end key rENTER in the same manner as described above with reference to FIG. is designed to be entered.

In this way, when numerical data is entered one digit at a time using the numeric keypad, the signal processing circuit 14 operates the character generating means 22 based on the data taken in one digit at a time, and displays a predetermined digit, for example, a 5-digit input data display. 23, characters corresponding to the input data are displayed sequentially from the upper digits to the lower digits.

Further, the signal processing circuit 14 stores the frequency data of each channel by writing numerical data taken in from the numeric keypad into the nonvolatile memory 24 when the end key rENTER is operated.

In the above configuration, the signal processing circuit 14 executes frequency presetting processing for each channel according to the processing procedure shown in FIG. That is, in step sP1, after starting the program, the signal processing circuit 14 executes step SP1.
After clearing the digit register 25 to zero in step SP2, the process moves to step SP3.

The digit register 25 is built into the signal processing circuit 14, for example, and counts up by "1" each time data is fetched from the key matrix 21, thereby allowing the number of digits of data to be fetched into the signal processing circuit 14. Count the numbers and go.

Step SP3 is the end key rE of the key matrix 21
By determining whether data has been input from NTERJ, it is confirmed whether or not the manual key operation has been completed.

When the signal processing circuit 14 obtains a negative result in step SP3, the signal processing circuit 14 moves to the next step SP4 and takes in numerical data for one digit, and then adds "+1" to the digit register 25 in the next step SP5. Thereafter, the process returns to step SP3 described above. Thus step 5P3-3P
By the loop of 4-3P5-3P3, the signal processing circuit 1
4 takes in numerical data one digit at a time, and stores the number of digits taken in in the digit register 25.

When the data from the end key rENTERJ is input from the key matrix 21 to the signal processing circuit 14, the signal processing circuit 14 determines this in step SP3 and moves to step SP6.

In this step SP6, by determining whether the contents of the digit register 25 have reached the maximum number of digits, 5,
It is checked whether the number of digits of the numerical data taken in by the signal processing circuit 14 has exceeded the predetermined maximum number N.

If a positive result is obtained in step SP6, this means that the signal processing circuit 14 has taken in the numerical data with the maximum number of digits, N, so the signal processing circuit 14 moves to step SP7 to take in the numerical data. After storing the numerical data in the nonvolatile memory 24, the program for inputting the numerical data is ended in step SP8.

On the other hand, if a negative result is obtained in step S, the signal processing circuit 14 moves to step SP9 and reads the contents of the digit register 25. As a result, the contents of the digit register 25 are "0", "1", and "2", respectively.
”, “3”, and “4”, the signal processing circuit 14 performs steps 5P10, 5PII, and 5P12.5P13, respectively.
．． Move to 5p14. These steps 5PIO~5PI
4 sets 0 to the difference N-M between the number of digits M of the numerical data taken into the signal processing circuit 14 and the maximum number of digits N (i.e., the remaining number of digits to which no numerical data has been input yet). It is a step.

That is, when the signal processing circuit 14 confirms that the contents of the digit register 25 are rOJ in step SP9, the remaining five digits are all "0" (that is, roo) in step 5PIO.

00''). Further, the signal processing circuit 14 determines that the contents of the digit register 25 are rlJ in step SP9.
When it is confirmed that all rOJ (i.e. ro 000J
) data. Further, the signal processing circuit 14 determines that the contents of the digit register 25 are "
2", the remaining last three digits are all "0" (i.e. ro OO
J). Further, the signal processing circuit 14 performs step S
When it is confirmed in P9 that the content of the digit register 25 is "3", all "0" (that is, "00") is entered into the last two digits in step SPI3.

Furthermore, when the signal processing circuit 14 confirms that the content of the digit register 25 is "1" in step SP9, it enters 0 into the last digit in step 5P14.

After performing such processing, the signal processing circuit 14 moves to the above-mentioned step 7, stores the numerical data in the nonvolatile memory 24, and ends the input program for the numerical data in step SP8.

In this way, the signal processing circuit 14 operates the end key rENTERJ before inputting the maximum number of digits when numerical data to be input is manually operated one by one from the upper digit. Sometimes, the remaining digits that have not yet been input are filled with numeric "0" data all at once and stored in the nonvolatile memory 24. This means that if there is an rOJ digit in the lower digits of the numerical data to be input, you can simply operate the end key rENTBRJ instead of operating the rOJ key each time. It means.

Therefore, key operations on the input device can be simplified accordingly.

In the above, an embodiment in which the present invention is applied to a DBS receiver has been described, but the scope of application is not limited to this, and the point is that numerical data of a predetermined number of digits can be input by keying one digit at a time. Widely applicable when presetting .

H Effects of the Invention As described above, according to the present invention, when data for which the number "0" should be entered in the lower digit is manually operated using the numeric keypad,
By operating the end key that indicates the end of the operation before reaching the maximum digit, the number "0" data is entered into the remaining digits, compared to the case where rOJ data is entered into the remaining digits one by one. This further simplifies the data input operation.
