Abstract

PURPOSE:To simplify the operation of inputting again in the case of erroneous inputting when inputting the figure of N digits one by one, by replacing the input figure from the first digit as a reinputting when N+1th input figure is specified figure. CONSTITUTION:A signal processing circuit that inputs the figure of five digits that indicates frequency to be set to a channel selecting circuit 15 stores a figure inputted from key matrix 21 once in a figure register 31 and then stores successively to a digit indicated by the digit register 32 of a frequency register 33. When an ENTER key is inputted by sixth inputting, the numerical value of the frequency register 33 is transmitted to a nonvolatile memory 34 and the channel selecting circuit 15. When a figure key is inputted and the figure is a specified value (1 when 11,700GHz-12,200GHz is selected), it is judged as the reinputting for correcting erroneous operation, and the storing is made again from the first digit of the frequency register 33.

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 that inputs numerical data of a predetermined number of digits manually.

B. Summary of the Invention The present invention provides an input display device that inputs and displays data of a predetermined number of digits one by one. If the number is not a predetermined number, it is ignored without being treated as valid data, thereby simplifying the re-input operation.

C Conventional technology DB S (direct-broadcast 5
(atellite) broadcasting allows receivers scattered over a wide area to directly receive broadcast waves arriving from broadcasting satellites using small parabolic antennas. It is being considered that information can be transmitted from the center to each branch via a receiver installed in each branch. 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.

The minimum unit of frequency that can be preset here is a value that maintains a frequency interval that does not cause interference or disturbance between each channel, and is specified when presetting the frequency of each channel accordingly. When presetting the required number of digits of the frequency, it is necessary to input the numerical data of this predetermined number of digits without excess or deficiency.

D Problems to be Solved by the Invention By the way, as a means to preset 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 can be preset by using a numeric keypad, for example. One possible method is to input the frequency assigned to each channel manually one digit at a time by sequentially entering a predetermined number of digits.
In the case of 2), 2 digits above the decimal point and 3 digits below the decimal point (
Numerical data (total of 5 digits) must be operated sequentially 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)-(7)-(0)-(03-CE
Selectively operate each key in the order of NTER).

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

The present invention has been made in consideration of the above points, and aims to simplify the effort required for input operations as much as possible by effectively processing the erroneously input data when numerical data input operations are erroneous. That is.

E Means for Solving the Problem In order to solve this problem, in the present invention, in an input display device that inputs and displays numerical data with a maximum number of N digits one by one, the first to Nth digits are After entering numeric data, when entering the (N+1)th digit numeric data (31
, 32, 33) If the (N+1)th digit numeric data corresponds to a number other than a predetermined number, the (N+1)th digit numeric data is changed to the 1st to Nth digits. In contrast, if the (N+1)th digit numeric data corresponds to the predetermined numeric data, the (N+1)th digit numeric data is Process so as to replace it as data that replaces the first digit numeric data (
Step 5P25-3P26-3P27-3P28-3
PI).

2 After entering the numerical data of N digits (maximum number of digits), press the end key rE
If new numerical data is input without operating NTERJ, the signal processing circuit 14 determines that numerical data has been input again (step 5P25).

At this time, if the first data (first digit data) of the re-input data is a number other than the predetermined number (“1” in the example), the signal processing circuit 14 converts the numerical data into valid data. is ignored without processing. As a result, the user can immediately perform the re-input operation from the beginning as if the erroneous input operation did not occur, thereby further simplifying the re-input operation.

If this is not done, even if the user immediately realizes that he or she made a mistake in inputting the first numeric data, the user must enter a predetermined number of digits before trying again. This requires a complicated time and effort in which input operations cannot be performed, but according to the present invention, such a complicated time and effort can be omitted.

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

In FIG. 2, 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 S1 given from the channel selection circuit 15.

The channel selection circuit 15 is controlled by a channel selection command signal S2 generated in a signal processing circuit 14 having a microcomputer configuration, for example, and sends out a channel selection signal S1 corresponding to the channel selection command signal 132.

A key matrix 21 including the input device 1 is connected to the signal processing circuit 14, and when each key of the key matrix 21 is selectively operated, corresponding code data is taken into the signal processing circuit 14.

In this embodiment, the signal processing circuit 14 inputs the input numerical data from the numeric keypad and then presses the end key rENTE.
When the RJ key is operated, it is determined that the data input operation has been completed.

That is, when numerical data is entered one digit at a time using the numeric keypad, the signal processing circuit 14 stores the data taken in one digit at a time in the numeric register 31, and then operates the character generating means 22 based on the stored data. The characters corresponding to the predetermined digits, for example, five digits, are displayed one by one on the numerical display 23.

The signal processing circuit 14 then stores the number of digits of the input numerical data in the digit register 32.

Further, when the sequentially input numerical data is frequency numerical data, the signal processing circuit 14 stores the numerical data stored in the numerical register 31 in the frequency register 33, and stores the numerical data stored in the numerical register 31 in the frequency register 33.

Further, the signal processing circuit 14 is configured to preset the frequency data of each channel by storing the numerical data stored in the frequency register 33 in the nonvolatile memory 34 when the end key rENTERJ 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, after starting the program in step SP1, it enters a state in which it waits for key data to be input from the key matrix 21 in step SP2, and when numerical data regarding the frequency is input, the signal processing circuit 14 executes in step SP3. Move to.

In step SP3, the signal processing circuit 14 stores the numerical data input from the key matrix 21 in the numerical register 31, and then proceeds to the next step SP4 to read the contents of the digit register 32.

When the signal processing circuit 14 reads that the content of the digit register 31 is rOJ, the signal processing circuit 14 moves to step SP5 and transmits the content of the digit register 31 to the most significant digit, that is, the first digit, of the numeric display 23 via the character generation means 22. After displaying it on the eye, the process moves to step SP6 and the contents of the number register 31 are entered into the first digit of the frequency register 33. In this manner, the signal processing circuit 14 completes the processing of the first digit frequency numerical data, and after adding "+1" to the digit register 32 in the next step SP7, returns to the above-mentioned step SP1. As a result, the signal processing circuit 14 enters a state in which it waits for new key manual data in step SP2.

Subsequently, when frequency numeric data is input from the key matrix 21, the signal processing circuit 14 determines this in step SP2, enters the loop of steps 5P3-3P4 described above, and inputs new numeric data into the numeric register 31. At the same time, the contents of the digit register 32 are read.

At this time, since the contents of the digit register 32 have been added with "+1" and become "1" in the above-mentioned step SP7, the signal processing circuit 14 moves to step SP8 based on the reading result and reads the contents of the numeric register 31. After displaying the data in the second digit of the numerical display 23 via the character generating means 22, the data in the numerical register 31 is entered in the second digit of the frequency register 33 in step SP9. In this way, the signal processing circuit 14 has finished processing the second digit data of the frequency data, and after adding "+1" to the digit register 32 in step SP7, the signal processing circuit 14 adds "+1" to the digit register 32 in step SP7.
- The process returns to the loop of 3P2 and enters a state in which it waits for new numerical data to be input from the key matrix 21.

Similarly, the third and fourth digits of the frequency numerical data,
When the numerical data for the fifth digit is sequentially input from the key matrix 21, the signal processing circuit 14 performs each step (SF3-3P4-3P10-3PI 1-3P?-
3PI-3P2), (SF3-5P4-SPI 2-5
PI 3-5P7-3PI-SF3), (SF3-SF
3-3P14-5P15-3P7-3PI-SF3) The numerical data sequentially input into the numerical register 31 through the loop of After displaying the data in the digit, the data in the number register 31 is stored in the third, fourth, and fifth digits of the frequency register 33, respectively. Here, the signal processing circuit 14 specifies the number of digits of the next input data by adding "+1" to the digit register 32 in step SP7 every time new numerical data is input. being done.

By inputting the five-digit numerical data in this way, the input of the frequency numerical data to the signal processing circuit 14 is completed, and therefore the user presses the end key rE of the input device l.
By operating NTERJ, the signal processing circuit 14 is informed that the input operation has been completed.

At this time, the signal processing circuit 14 selects the end key rENTERJ.
It is detected in step SP2 that the key has been operated, and the process enters the loop of step SP21.

In this step 5P21, the signal processing circuit 14 stores the five-digit frequency data stored in the frequency register 33 in the nonvolatile memory 34, and thus presets the frequency data in the receiver.

Subsequently, in step 5P22, the signal processing circuit 14 performs
The frequency data of the frequency register 33 is sent to the broadcast wave receiving section 12.
is stored in the channel selection circuit 15 of the broadcast wave receiving section 1.
2. Preset the frequency data of the receiving channel.

In this way, the frequency receiving section 12 can perform a tuning operation on the channel selection circuit by reading out the preset frequency data from the nonvolatile memory 34 and supplying it to the channel selection circuit 15 when selecting a channel.

Furthermore, the signal processing circuit 14 moves to step 5P23, clears the digit register 32, and inputs the contents into the numerical value "
"O". As a result, the signal processing circuit 14 has completed the frequency data input operation by operating the end key rENTERJ, and henceforth inputs new data into the frequency register 33 and the first digit of the numerical value display 23. Clear the digit register 32 so that it can be used.

Thereafter, the signal processing circuit 14 returns to step SPI and returns to the state of waiting for a new key manual operation.

In this way, one cycle of the frequency data input operation is completed, but if the user makes a mistake in the input operation on the input device 1, input the 6th digit numerical data before operating the end key "ENTERJ". The input operation can be corrected by doing this.

In other words, if the user wants to correct the input value after inputting 5-digit frequency data, press the end key rENTE.
Before operating the RJ, input the frequency data to be corrected sequentially starting from the upper digit. First, when the first digit numerical data of the frequency data is input again, the signal processing circuit 14 determines this in step SP2 and proceeds to steps 5P3-3P4.
The loop of step 5P25 is entered through the loop of step 5P25. When viewed from the signal processing circuit 14 side, this input of numerical data means that the sixth digit numerical data has been taken in, and the signal processing circuit 14 determines whether or not the input data of the sixth digit is correct. make a judgment.

In this example, the DBS receiver is 11.700 (GH
z] to 12.199 (GHz), so the first digit of the frequency data to be set on the DBS receiver is "1".
Therefore, when inputting new 5-digit frequency data, if the first numeric data is incorrect, it is obvious that the operation was erroneous even without inputting the subsequent numeric data.

Therefore, the signal processing circuit 14 determines whether the content of the numerical register 31 is "1" in step 5P25, and determines whether the content of the numerical register 31 is "1".
'', the contents of the numeric register 31 are displayed on the most significant digit (ie, the first digit) of the numeric display 23 via the character generating means 22 in the next step 5P26. Subsequently, the signal processing circuit 14 inputs the data of the number register 31 into the first digit of the frequency register 33 in step 5P27, and then inputs the data of the number register 31 into the first digit of the frequency register 33 in the next step 5P28.
The register 32 is set to "1", and then the process returns to the first step SPI.

In this way, the signal processing circuit 14 determines that the numerical data newly input as the sixth digit data (meaning the first digit data of the re-input data) is the first digit number of the frequency to be preset. If the input data matches the numeric data allowed as the input data, the numeric display 23, frequency register 33, and digit register 32 will be operated in response to the input data as the first digit data of the re-input data. .

Therefore, when the user sequentially inputs the second to fifth digits of the numerical data that he wishes to re-enter, the signal processing circuit 14
performs this step sequentially (SP8-3P9), (SP 1
0-3P 11), (SP12-3P13), (SP
14-3P The data re-inputted by the loop of 15) is taken into the line (row).

In this case, after re-entering the 5th digit data, press the exit key rE
If you operate NTERJ, the above step 5P21-3
The re-input data can be stored in the nonvolatile memory 34 through the loop of P22-3P23.

In response, the user incorrectly entered the first digit of the data to be re-entered, and entered a number other than ``1'' (i.e., ``2'').
~ "O"), the first digit of the numerical data you want to re-enter is already incorrect, so the signal processing circuit 14
When a negative result is obtained in step 5P25, the process immediately moves to the above-mentioned step SPI, and returns to the state of waiting for the subsequent manual key operation.

In this case, the signal processing circuit 14 does not perform any processing on the data that was erroneously input into the numeric register 31, and therefore the erroneously input data is subsequently transferred to the key matrix 21.
It disappears when numeric data is entered from . In this way, when re-inputting, the signal processing circuit 14 ignores the data input due to the erroneous operation without processing it as valid data, if the input operation of the numeric data in the second digit is an erroneous operation. It turns out.

Therefore, if the configuration is as shown in FIG. 1, when the user inputs correct frequency data from the key matrix 21,
This is displayed one digit at a time on the numerical display 23, and when the end key rENTERJ is operated after a predetermined digit, that is, five digits worth of numerical data has been input, the input frequency data is stored in the nonvolatile memory 34. Can be preset.

On the other hand, if the user wants to correct the input frequency data immediately after inputting the 5-digit frequency data, the user can enter the numerical data that he or she wants to re-enter using the numeric keypad 21 before operating the "end key rENTER". All you have to do is input it sequentially, and the frequency data re-entered at that time will be saved in the DB.
If the value is in the frequency range of the broadcast band assigned to the S receiver, the signal processing circuit 14 sequentially takes in the re-input frequency data one digit at a time, and then when the end key rENTERJ is operated, this value is Frequency data is preset in the nonvolatile memory 34.

On the other hand, if the contents of the first digit numerical data of the frequency data that you attempt to re-enter do not match the first digit number of the frequency band assigned to the DBS receiver, the signal processing circuit 14 This re-input data of the first digit is ignored without being processed as valid data. Therefore, the user can input the frequency data again without inputting the five-digit numerical data. Therefore, the user's input operation can be simplified accordingly.

However, if such data is not invalidated,
Even if the user realizes that he or she made a mistake in inputting the first digit of the re-entered data, the user will have to wastefully input the remaining five digits of numerical data. If you do this, you won't have to perform such unnecessary operations.

In practice, if you use this function, even if you accidentally press a number key on the key matrix 21 after correctly inputting 5-digit preset data, the signal processing circuit 14 will ignore this data. , it is possible to process data input by the erroneous operation without adversely affecting numerical data that has already been input correctly.

In the above, an embodiment in which the present invention is applied to a display device of a receiver used for DBS broadcasting has been described.
The present invention is not limited to this, and can be widely applied to devices having an input display device that inputs and displays numerical data by key operation.

H Effects of the Invention As described above, according to the present invention, if the first digit data input during a re-input operation corresponds to a numerical value other than the permissible numerical value, the input numerical data is treated as valid data. By ignoring the information without processing it, the effort required for re-input operations can be further simplified.
