Description

  The present invention relates to a display device, a display control method, a display control program, and a communication system, and is suitably applied to, for example, a display device that displays a numeric string when inputting an IP (Internet Protocol) address.

Conventionally, when a character string composed of a plurality of words is displayed on a display unit with a limited number of display digits, there is a display device configured to perform omission display of the character string by erasing while scrolling the character ( For example, see Patent Document 1).
JP 2005-62497

  By the way, the data string displayed on the display device includes, for example, an IPv4 IP address that cannot be omitted. The IP address uses a total of 32 bits, divided into four 8 bits each. For example, a decimal number from “0” to “255” such as “211.9.36.148” is displayed in four fields. These numbers are arranged side by side, and these numerical values cannot be omitted.

  In a portable communication terminal device, there are cases where IP addresses of all digits cannot be displayed at the same time due to the display capability of the display unit. For example, as shown in FIG. 25A, when the data string of the IP address to be input is “134.097.215.001” configured over the first field F1 to the fourth field F4, every three digits. For a period “.” Representing a delimiter, a display capability of a maximum of 15 digits including the number of digits is required. For example, as shown in FIG. 25B, a communication terminal device having only a 7-digit display unit In this case, only the display range AR constituting a part of the IP address can be displayed, and the shortage is dealt with while scrolling.

  By the way, in the communication terminal device having such a configuration, even when the user wants to input the numerical value “001” of the fourth field F4 among the IP addresses with the cursor CS, as shown in FIG. May be entered as a single digit “1” by some users.

  However, in the communication terminal device, the IP address input to the display unit is recognized based on a three-digit numerical value constituting each item of the first field F1 to the fourth field F4. Therefore, as described above, the numerical value “001” of the fourth field is desired to be input. However, as shown in FIG. 25C, the single-digit numerical value “1” is simply input due to the difference in recognition for each user. In such a case, there is a problem that the communication terminal apparatus erroneously interprets this as “100” and communicates with the wrong access destination.

  The present invention has been made in consideration of the above points, and even when a data string in a range exceeding the display capability is input, a display device, a display control method, a display control program, and a display device that always prompts the user for accurate input A communication system is to be proposed.

  In order to solve such a problem, in the display device, the display control method, and the display control program of the present invention, a set of data strings that display a set of data strings in which a plurality of items that form a group by a plurality of digits of a predetermined minimum unit are connected. When a data string is input via a specified input indicator for designating a digit in a display means having a display capacity less than the total number of digits, and an item outside the display range exceeding the display capacity of the display means is input. The data string is shifted and scrolled so that at least all of the multiple digits constituting the item are displayed on the display means, and the input indicator is moved to the most significant digit of the multiple digits constituting the item. Try to fix.

  Thereby, it is possible to guide the user to accurately input the minimum number of digits constituting the data string item by the scroll display range of the data string and the position where the input indicator is fixed.

  According to the present invention, there is provided a communication system constructed by a predetermined display device and a remote controller for remotely operating the display device. The display device includes a plurality of items that are grouped by a plurality of digits of a predetermined minimum unit. Display means for displaying the aggregate of the data strings displayed, the display means having a display capacity less than the total number of digits of the aggregate, and the receiving means for receiving the data string corresponding to the user input operation transmitted from the remote controller; When receiving a command to input an item outside the display range that exceeds the display capability of the display means, the data string is shifted and scrolled so that at least all of the digits constituting the item are displayed on the display means. And a display control means for moving and fixing the input indicator to the most significant digit of the plurality of digits constituting the item. Input means for inputting an over data string by a user, to be provided with transmitting means for transmitting to the display device the input data string through an input operation of the user by the input means.

  As a result, the scroll display range of the data string displayed on the display device that has received a command from the remote controller and the fixed position of the input indicator for multiple digits of the minimum unit constituting the data string item The user can be guided to input correctly.

  According to the present invention, it is possible to guide a plurality of digits of the minimum unit constituting an item of the data string to be accurately input by the scroll display range of the data string and the position where the input indicator is fixed. Thus, it is possible to realize a display device, a display control method, a display control program, and a communication system that always prompts the user to input an accurate data string even when a data string exceeding the display capability is input.

  The wireless communication module 3 is provided with a display 23 with a 7-digit display on the surface of the main body. In order to establish a wireless communication link between the wireless communication module 3 and the server 2, the server can be remotely operated from the remote controller 4. 2 IP addresses can be input via the cursor CS of the display 23.

  Accordingly, when the wireless communication module 3 receives, for example, a streaming playback command from the remote controller 4 while being electrically connected to the cradle 5, the wireless communication module 3 receives the audio data from the server 2 and performs streaming playback accordingly. Can be output from the speaker SP.

(2) Circuit Configurations of Wireless Communication Module, Cradle, Server, and Remote Controller Here, circuit configurations of the server 2, the wireless communication module 3, the cradle 5, and the remote controller 4 will be described.

(2-1) Circuit Configuration of Wireless Communication Module First, the configuration of the wireless communication module 3 will be described with reference to FIG. The line communication module 3 is a wireless communication between the wireless communication module 3 and the server 2 based on various wireless LAN (Local Area Network) standards such as IEEE (Institute of Electrical and Electronics Engineers) 802.11a / b / g. The MPU (Micro Processing Unit) 20 performs overall control by executing a basic program read from a built-in memory (not shown), and various application programs (display control program, etc.) ) Is executed, an IP address display processing procedure to be described later is executed.

  In practice, when the MPU 20 of the wireless communication module 3 is mounted on the cradle 5 and electrically connected to the cradle 5, for example, a list for requesting a music title list of audio data stored in the server 2 A request signal is wirelessly transmitted to the server 2 by the wireless LAN adapter 21.

  As a result, when the MPU 20 of the wireless communication module 3 receives the music title list of the audio data transmitted from the server 2 via the wireless LAN adapter 21, the received music title list is displayed on the display 23 via the display controller 22. To display. Incidentally, the music title list in this case shows, for example, music titles corresponding to the respective audio data stored in the server 2.

  This display 23 has, for example, a 7-segment LED (Light Emitting Diode) having a display capability of a maximum of 7 digits due to display area limitations and cost requirements. When displaying a character string such as a music title, the display 23 The character portion in a range that cannot be completely displayed is scrolled.

  The MPU 20 of the wireless communication module 3 displays the list on the display 23 in this way, and then performs a reproduction operation for selecting arbitrary audio data from the audio data described in the music title list via the operation keys 24. When the wireless LAN adapter 21 transmits a voice data request signal for requesting the selected voice data to the server 2.

  As a result, when the MPU 20 of the wireless communication module 3 starts transmitting the audio data corresponding to the audio data request signal from the server 2, the audio data is received while receiving the audio data via the wireless LAN adapter 21. The data is written in the buffer 25 in order from the finished part. Incidentally, the audio data transmitted from the server 2 is, for example, linear PCM (Pulse Code Modulation) on which digital processing such as decoding processing is performed on the server 2 side.

  Then, when the MPU 20 of the wireless communication module 3 accumulates, for example, several seconds of audio data in the buffer 25, the collected audio data is sent to the DA converter 26 and erased from the buffer 25, and again for several seconds of audio data in the buffer 25. Wait until it accumulates. The DA converter 26 obtains an audio signal by performing digital-analog conversion processing on the sent audio data, and the audio signal is obtained via the module side terminal 27 connected to the cradle side terminal 5B. Send to.

  As a result, sound based on the sound signal sent to the cradle 5 is output from the speaker SP built in the cradle 5. Incidentally, in the following description, the process of digital-to-analog conversion in order from the part where the audio data has been received is also referred to as a streaming reproduction process.

  In this way, when the wireless communication module 3 is connected to the cradle 5, the speaker built in the cradle 5 receives the sound obtained by streaming the sound data transmitted from the server 2 wirelessly. It can be output via SP. Further, when the wireless communication module 3 is connected to the cradle 5 as described above, a built-in battery (not shown) is charged by the power supplied from the cradle 5 through the module side terminal 27.

  Further, the wireless communication module 3 is provided with an infrared light receiving unit 28, and an infrared signal transmitted from the remote controller 4 is received by the infrared light receiving unit 28 and converted into a command. That is, the wireless communication module 3 not only executes various processes according to operations on the operation keys 24 but also executes various processes according to remote operations from the remote controller 4.

(2-2) Circuit Configuration of Cradle Next, the circuit configuration of the cradle 5 will be described with reference to FIG. The cradle 5 is operated by a power source supplied through an AC adapter (not shown), and the MPU 30 performs overall control by executing a basic program read from an internal memory (not shown) of the MPU 30. Has been made.

  In practice, for example, when the power-on operation is performed via the operation key 31, the cradle 5 is activated in response to the operation, and the wireless communication module 3 is placed on the placement unit 5A and connected thereto. For example, power is supplied to the wireless communication module 3 via the cradle side terminal 5B.

  When the audio signal sent from the wireless communication module 4 is received via the cradle side terminal 5B with the wireless communication module 3 connected in this manner, the MPU 30 of the cradle 5 receives the audio signal. An analog-digital converter (hereinafter also referred to as an AD converter) 32 is input.

  The AD converter 32 obtains audio data by performing analog-digital conversion processing on the audio signal, and sends the audio data to the sound processor 33. The sound processor 33 performs digital processing such as equalizing processing on the audio data sent from the AD converter 32, and then sends the digitally processed audio data to the DA converter 34.

  The DA converter 34 obtains an audio signal by performing digital-analog conversion processing on the audio data sent from the sound processor 33, and sends the audio signal to the amplifier 35. The amplifier 35 performs an amplification process on the audio signal, and then outputs a sound based on the amplified audio signal via a speaker SP connected to a speaker terminal (not shown).

  In this way, the cradle 5 charges the wireless communication module 3 connected via the cradle side terminal 5B, and the sound based on the sound signal sent from the wireless communication module 3 is transmitted via the speaker SP. It can be output.

  The MPU 30 of the cradle 5 is also configured to display various information such as volume and current time on the display 37 via the display controller 36.

(2-3) Server Circuit Configuration Next, the circuit configuration of the server 2 will be described with reference to FIG. The server 2 can wirelessly communicate with the wireless communication module 3 via the wireless LAN adapter 44 based on the same wireless LAN standard as the wireless communication module 3.

  Further, the CPU 40 of the server 2 develops a basic program read from a hard disk drive 41 or a ROM (Read Only Memory) 42 to a RAM (Random Access Memory) 43 and executes it, thereby performing overall control and performing various processes. It is made to run. Further, the CPU 40 is adapted to temporarily store data handled in these various processes in the RAM 43 as appropriate.

  In practice, for example, when receiving the list request signal transmitted from the wireless communication module 3 via the wireless LAN adapter 44, the CPU 40 converts the audio data stored in the hard disk drive 41 according to the list request signal. The corresponding music title list is transmitted to the wireless communication module 3 via the wireless LAN adapter 44. Incidentally, this music title list is generated, for example, when audio data is stored in the hard disk drive 41 and stored in the hard disk drive 41.

  When the CPU 40 receives the audio data request signal transmitted from the wireless communication module 3 via the wireless LAN adapter 44 after transmitting the music title list to the wireless communication module 3, the CPU 40 designates the audio data request signal. The read audio data is read from the hard disk drive 44. Incidentally, here, it is assumed that the audio data recorded in the hard disk drive 44 is compression-encoded.

  The CPU 40 subjects the audio data read from the hard disk drive 44 to digital processing such as decoding processing by the sound processor 45, and then wirelessly communicates the audio data subjected to the digital processing via the wireless LAN adapter 44. Send to module 3. Incidentally, the audio data digitally processed by the sound processor 45 is, for example, linear PCM, and the audio data of the linear PCM is transmitted to the wireless communication module 3.

  In this way, in response to a request from the wireless communication module 3, the server 2 supplies the wireless communication module 3 with a music title list of audio data stored in the hard disk drive 44 and audio data subjected to predetermined digital processing. In contrast, wireless transmission is performed.

(2-4) Circuit Configuration of Remote Controller Next, the configuration of the remote controller 4 will be described with reference to FIG. As shown in FIG. 1, the remote controller 4 is operated by pressing the menu button 51, the enter key 52, the right button 53, the left button 54, the upper button 55, and the lower button 56 provided on the surface of the main body. When the MPU 50 recognizes this, various commands corresponding to the pressing operation are transmitted to the wireless communication module 3 via the infrared light emitting unit 57 by infrared.

  Here, the remote controller 4 is used to remotely input an IP address for accessing the server 2 from the wireless communication module 3 when the wireless communication module 3 and the server 2 establish a wireless communication link. Yes, the IP address input mode is entered in response to the pressing operation on the menu button 51.

  In the IP address input mode, the MPU 50 of the remote controller 4 transmits various commands to the wireless communication module 3 in accordance with the pressing operation on the right button 53 or the left button 54 to display the wireless communication module 3 with a 7-digit display. The position of the cursor CS on the display 23 can be moved left and right.

  In addition, the MPU 50 of the remote controller 4 transmits various commands to the wireless communication module 3 in response to a pressing operation on the upper button 55 or the lower button 56 in the IP address mode, so that the cursor CS on the display 23 of the wireless communication module 3 is transmitted. The numeric value specified by can be increased or decreased.

  Further, in the IP address input mode, the MPU 50 of the remote controller 4 finishes the input operation of the IP address according to the pressing operation on the right button 53, the left button 54, the up button 55, and the down button 56, and the enter key 52 performs the pressing operation. When it is recognized that the wireless communication module 3 is transmitted by infrared to the wireless communication module 3, a command indicating that the IP address displayed on the display 23 of the wireless communication module 3 is determined at that time is wirelessly transmitted based on the IP address. A wireless communication link between the communication module 3 and the server 2 is established.

(3) Functions of Cradle, Wireless Communication Module, Remote Controller, and Server Here, the wireless communication module 3 is mounted on the mounting portion 5A of the cradle 5, and the cradle 5 and the wireless communication module 3 are electrically connected. The functions of the cradle 5, the wireless communication module 3, the remote controller 4 and the server 2 will be described.

  As shown in FIG. 7, when the cradle 5 and the wireless communication module 3 are electrically connected, the wireless communication module 3 performs streaming playback from the server 2 according to the infrared signal received from the remote controller 4. The audio data is received by wireless communication, and a reproduction process is performed on the audio data to obtain an audio signal, which is sent to the cradle 5.

  The cradle 5 can stream and reproduce the music data received from the server 2 via the wireless communication module 3 by outputting sound based on the sound signal sent from the wireless communication module 3 from the speaker SP. The communication module 3 is charged.

  As described above, when the cradle 5 and the wireless communication module 3 are electrically connected, the function of the wireless communication module 3 is to receive the audio data from the server 3 by wireless communication and to stream the received audio data. The function of the cradle 5 is the output of audio based on the audio data stream-processed by the wireless communication module 3 and the charging of the wireless communication module 3. The function of the remote controller 4 is for the wireless communication module 3. It is a remote operation, and the function of the server 2 is to provide voice data to the wireless communication module 4 by wireless communication.

(4) IP Address Input Display Method Next, a display method when an IP address is input to the display 23 of the wireless communication module 3 in response to a user pressing operation on the remote controller 4 will be described.

  Here, the IP address indicating the access destination for the wireless communication module 3 to wirelessly communicate with the server 2 uses a total of 32 bits divided into four 8 bits each. For example, as shown in FIG. In this way, decimal numbers from “0” to “255” are arranged in the first field F1 to the fourth field F4, respectively, as in the numeric string “192.168.100.187”. It is expressed by a 15-digit number string with a period “.” As a delimiter.

  On the other hand, since the display 23 of the wireless communication module 3 has a display capability of a maximum of 7 digits, it cannot display all 15 digits of IP addresses at a time, as shown in FIG. In the first input stage, the numeric string (“192.168”) of the display range AR1 from the first 1st digit to the 7th digit of the total 15-digit IP address is displayed, and the hidden part after that is displayed. A numeric string (".100.187" is scrolled and displayed.

  Further, the MPU 20 of the wireless communication module 3 displays a cursor CS at the first digit of the seven-digit display 23 and can input or edit a user-desired numerical value via the cursor CS. .

  Subsequently, as shown in FIGS. 9A to 9D, the MPU 20 of the wireless communication module 3 moves the cursor CS from the first digit according to the user's pressing operation on the right button 53 of the remote controller 4. The second digit, the third digit, and the fourth digit are skipped and sequentially moved to the fifth digit, and the numeric value of the digit designated by the cursor CS can be input or edited.

  Here, since the MPU 20 of the wireless communication module 3 is not the position where the numerical value is to be specified for the fourth digit with a period “.” That exists as a separator between every three digits, the cursor CS has three digits. The cursor CS is moved to the fifth digit when the right button 53 is pressed once while the eye is positioned.

  By the way, the MPU 20 of the wireless communication module 3 moves the cursor CS further to the right even when the right button 53 is pressed after moving the cursor CS to the fifth digit in the seven-digit display 23. It has been made so that there is nothing.

  This makes it possible to visually and intuitively recognize that when a user inputs an IP address, it is necessary to input a three-digit numerical value after a period “.” That exists as a separator between three-digit numbers. Accordingly, the input field for 3 digits is always left and displayed after the cursor CS.

  That is, the MPU 20 of the wireless communication module 3 moves the cursor CS to the fifth digit of the seven-digit display 23 and then always displays the input column for three digits after the cursor CS, for example, Even when the user inputs a three-digit number string “001” after the period “.”, The MPU 20 of the wireless communication module 3 receives a numerical value by erroneously inputting the single-digit numerical value “1”. It is designed to prevent erroneous recognition of “100”.

  This is because it is necessary to input the numerical value “001” via the display 23. However, as a human characteristic, the numerical value “00” tends to be omitted, so the numerical value “1” is input. In order to avoid this, the wireless communication module 3 presents an input field that makes it clear that the user can input a three-digit numerical value.

In MPU20 of wireless communication module 3 in that you said, when to enter the IP address on the display 23, for example, if you display a three-digit number after the cursor CS ". 0 00" as a default, the numerical value ". 0 01 "and the display on the" 1 "to the digit that is specified will be input by the cursor CS where there is a need to enter". 1 00 becomes a ", it is possible to notice that you have erroneous input to the user's own , So that the correct numerical value “.001” can be input.

  Thus, the MPU 20 of the wireless communication module 3 can guide the user to input the numerical value of the IP address composed of the first field F1 to the fourth field F4 in every three digits in the input format desired by the wireless communication module 3. Access to an access destination other than desired is avoided in advance, and a wireless communication link with the server 2 can be reliably established.

  Further, the MPU 20 of the wireless communication module 3 moves the IP address display range to the right as shown in FIG. 10A from the state where “192.168” is displayed on the seven-digit display 23 (FIG. 9D). Even when the numeric string (“92.168.”) In the display range AR2 moved by one digit is scroll-displayed, as shown in FIG. 10 (B), the fifth digit position on the seven-digit display 23 is displayed. The cursor CS is fixed at (the position where the numerical value “6” is displayed).

  Further, the MPU 20 of the wireless communication module 3 starts from the state in which the numeric string “92.168.” Is displayed on the seven-digit display 23 as shown in FIG. 10 (B), as shown in FIG. 10 (C). When scrolling the numeric string (“2.168.1”) in the display range AR3, in which the display range is further moved to the right by one digit, as shown in FIG. The cursor CS is fixed at the fifth digit position 23 (position where the numerical value “8” is displayed).

  That is, even when the MPU 20 of the wireless communication module 3 scrolls the IP address displayed on the seven-digit display 23 while sequentially moving the IP address to the right by one digit at a time, the position of the cursor CS is the seven-digit display. It is fixed at the fifth digit on the display 23, and an input area for three digits is always secured from there.

  By the way, the MPU 20 of the wireless communication module 3 displays the numeric string “2.168.1” of the display range AR3 constituting the IP address on the seven-digit display 23 as shown in FIGS. 11 (A) and 11 (B). When the IP address is scroll-displayed in response to a single pressing operation on the right button 53 of the remote controller 4 from this state, the numbers are separated by three digits as shown in FIGS. 11C and 11D. In order to avoid positioning the cursor CS at the period “.”, The numeric string “168.100” of the display range AR4 that jumps over the period “.” Is displayed on the display 23.

  As a result, when the MPU 20 of the wireless communication module 3 scrolls and displays in response to a single pressing operation on the right button 53 of the remote controller 4, it is not necessary to input a numerical value among the 15-digit IP addresses. The position of the cursor CS at the period “.” Of the 12th digit and the 12th digit is avoided in advance so that the user does not have to perform an unnecessary pressing operation on the right button 53.

  Incidentally, as shown in FIGS. 12A and 12B, the MPU 20 of the wireless communication module 3 becomes the input target of the numeric string “92.168.” Of the display range AR2 that is not from the top of the IP address, for example. If the user presses the left button 54 of the remote controller 4, the numeric string “192.168” of the display range AR1 from the top of the IP address is displayed as shown in FIGS. 12C and 12D. The display is scrolled as an input object 23.

  At this time, as shown in FIGS. 12B and 12D, the MPU 20 of the wireless communication module 3 displays the cursor CS on the display 23 in a state where the cursor CS is fixed to the fifth digit of the seven-digit display. An entry field for three digits after the cursor CS can be left.

  The MPU 20 of the wireless communication module 3 displays the numeric string “192.168” corresponding to the display range AR1 from the beginning of the IP address on the display 23 as shown in FIG. When the left button 54 of the remote controller 4 is pressed from the state in which the cursor CS is displayed, there is no need to scroll the display range AR1 further to the left in this display state, so as shown in FIG. The cursor CS is moved to the third digit of the display 23 and displayed.

  At this time, the MPU 20 of the wireless communication module 3 moves the cursor CS from the fifth digit to the third digit because the fourth digit of the display 23 is a period “.” Which is not necessary for inputting the IP address. Has been made.

  Furthermore, when the left button 54 of the remote controller 4 is pressed down from the state where the cursor CS is displayed at the third digit of the display 23 as shown in FIG. When the cursor CS is moved to the second digit of the display 23 and displayed as shown in FIG. 13 (C), and the left button 54 of the remote controller 4 is pressed from the display state, the cursor CS is shown in FIG. 13 (D). Thus, the cursor CS is moved to the first digit of the display 23 and displayed.

(5) IP Address Display Processing Procedure Next, when the MPU 20 of the wireless communication module 3 inputs an IP address to the seven-digit display 23 using the IP address input display method as described above in accordance with the display control program. The display processing procedure will be described with reference to the flowcharts of FIGS.

  Here, the IP address given as the edit data string by the MPU 20 of the wireless communication module 3 is a total of 15 bits including a period “.” That is a delimiter every three digits as shown in FIG. This will be described below using “192.168.100.187”.

  As shown in FIG. 19, the MPU 20 of the wireless communication module 3 scrolls while changing the display range AR1 to AR9 of the IP address on the display 23 that can display 7 digits out of all 15 digits of the IP address. It can be displayed. Here, description will be given below assuming that the number of characters L = 7 that can be displayed on the display 23.

  Note that the symbol C used in the flowchart of the routine RT1 (FIG. 14) indicates the edit position of the IP address consisting of all 15 digits indicated by the cursor CS, and the symbol M is a 7-digit display. This is a variable used for calculation to leave an input field for 3 digits after the cursor CS on the display 23 of FIG.

  This variable M is given by

Indicated by That is, since the number L of characters on the display 23 is 7, M = 5 in this case.

  The symbol S1 used in the flowchart of the subroutine SRT2 (FIG. 15) indicates the display start position with respect to the display 23 of the IP address, which is the edit data string, by the number of digits. The edit position specified by is indicated by the number of digits on the display 23.

  In practice, the MPU 20 of the wireless communication module 3 enters from the start step of the routine RT1, moves to the next step SP1, sets "1" as the first digit number C of the IP address designated by the cursor CS, and executes the next subroutine. Move to SRT2.

  As shown in FIG. 15, the MPU 20 of the wireless communication module 3 enters from the start step of the subroutine SRT2 and moves to the next step SP21, where the number of digits C indicating the editing position of the IP address designated by the cursor CS and the variable M It is determined whether or not the relationship satisfies C ≧ M. In this case, since C = 1 and M = 5, a negative result is obtained. At this time, the MPU 20 of the wireless communication module 3 proceeds to the next step SP22.

  In step SP22, the MPU 20 of the wireless communication module 3 sets the first digit as the display start position S1 with respect to the display 23 of the IP address, and also sets the first digit on the display 23 as the editing position S2 designated by the cursor CS of the display 23. The eye (in this case, editing position S2 = number of digits C (= 1)) is set, and the process proceeds to the next step SP24.

  In step SP24, the MPU 20 of the wireless communication module 3 displays L characters (7 characters) from the first digit of the IP address (FIG. 18) designated as the display start position S1 on the 7-digit display 23. Control goes to step SP25.

  In step SP25, the MPU 20 of the wireless communication module 3 displays the cursor CS at the first digit, which is the editing position S2 on the display 23, and proceeds to step SP3 of the routine RT1.

  That is, as shown in FIG. 20A, the MPU 20 of the wireless communication module 3 sets the first digit as the display start position S1 for the display 23 of the IP address, and therefore the display range AR1 for the first seven digits in the IP address. A number string “192.168” is displayed on the display 23, and the first digit is set as the editing position S2 on the display 23. Therefore, the cursor CS is displayed on the first digit of the display 23.

  Similarly, the MPU 20 of the wireless communication module 3 obtains a negative result when the number C of digits of the IP address designated by the cursor CS takes the values “2” and “3” in step SP21, and displays the IP address in step SP22. 23, the first digit is set as the display start position S1, and the same value as the digit number C is set as the digit number S2 on the display 23.

  As a result, the MPU 20 of the wireless communication module 3 displays on the display 23 a numeric string “192.168” corresponding to the display range AR1 for the first seven digits of the IP address, as shown in FIGS. 20 (B) and 20 (C). In addition, the cursor CS designated as the editing position S2 of the display 23 is displayed in the second digit and the third digit.

  In step SP3 (FIG. 14), when the MPU 20 of the wireless communication module 3 recognizes that the user has made a key input to the various buttons of the remote controller 4, the process proceeds to the next step SP4.

  In step SP4, the MPU 20 of the wireless communication module 3 determines whether or not the key input target is the right button 53. If an affirmative result is obtained, the process proceeds to the edit position right shift process of the next subroutine SRT5. .

  As shown in FIG. 16, the MPU 20 of the wireless communication module 3 has the value of the number of digits C of the IP address designated by the cursor CS before the key input to the right button 53 is “3”, “7”, or “ 11 ”is determined.

  If an affirmative result is obtained here, this means that the value of the number of digits C designated as the editing position of the IP address designated by the cursor CS before key input is “3”, “7” or “11”. , That is, in response to the pressing operation on the right button 53, the cursor CS is positioned at a period “.” Corresponding to a delimiter every three digits by only one right movement process. When this happens, the MPU 20 of the wireless communication module 3 proceeds to the next step SP32.

  In step SP32, the MPU 20 of the wireless communication module 3 uses the following equation for the value of the number of digits C of the IP address specified by the cursor CS before key input is performed.

Is used to calculate a new value of the number of digits C, and the process returns to the subroutine SRT2 of the routine RT1.

  On the other hand, if a negative result is obtained in step SP31, this means that the value of the number of digits C of the IP address designated by the cursor CS before key entry is “3”, “7” or “11”. In this case, the MPU 20 of the wireless communication module 3 moves to the next step SP33.

  In step SP33, the MPU 20 of the wireless communication module 3 determines whether or not the value of the number of digits C of the IP address designated by the cursor CS before key input is “15”.

  If an affirmative result is obtained here, this means that the value of the number of digits C of the IP address designated by the cursor CS is “15”, and the number of digits C greater than this is designated by the cursor CS. Therefore, the processing returns to the subroutine SRT2 of the routine RT1 without performing any processing.

  On the other hand, if a negative result is obtained in step SP33, this means that the value of the number of digits C of the IP address designated by the cursor CS before the key input is performed is edited when the key input is performed. This means that the MPU 20 of the wireless communication module 3 moves to the next step SP34.

  In step SP34, the MPU 20 of the wireless communication module 3 uses the following equation for the value of the number of digits C of the IP address specified by the cursor CS before key input is performed.

Is used to calculate a new value of the number of digits C, and the process returns to the subroutine SRT2 of the routine RT1.

  Then, the MPU 20 of the wireless communication module 3 obtains an affirmative result when the relationship between the number of digits C of the IP address designated by the cursor CS and the variable M satisfies C ≧ M in step SP21 of the subroutine SRT2. The process proceeds to step SP23.

  In step SP23, the MPU 20 of the wireless communication module 3 uses the following equation as the display start position S1 for the display 23 of the IP address.

And the edit position S2 designated by the cursor CS of the display 23 is set as the number of digits on the display 23 (in this case, the edit position S2 = variable M (= 5)), and proceeds to the next step SP24.

  In step SP24, the MPU 20 of the wireless communication module 3 is set as the display start position S1 as shown in FIG. 20D when the value of the number of digits C of the IP address designated by the cursor CS is “5”, for example. The L characters (7 characters) from the 1st digit of the IP address (FIG. 18) are displayed on the 7-digit display 23, and the process proceeds to the next step SP25.

  In step SP25, the MPU 20 of the wireless communication module 3 displays the cursor CS at the fifth digit which is the editing position S2 (= variable M) on the display 23 as shown in FIG. Control goes to step SP3.

  Similarly, the MPU 20 of the wireless communication module 3 obtains a positive result when the number C of digits of the IP address designated by the cursor CS in step SP21 takes a value exceeding “5” (“6” to “15”). By executing the processing of step SP23 to step SP25 in the same manner as shown in FIG. 20, as shown in FIGS. 20E to 20L, display ranges AR2 to AR9 corresponding to a 7-digit number string in the IP address are displayed. The display is scrolled on the display 23 while sequentially shifting, and the cursor CS is displayed with the cursor CS fixed at the fifth digit which is the editing position S2 (= variable M) on the display 23.

  Incidentally, the MPU 20 of the wireless communication module 3, as shown in FIGS. 20 (K) and 20 (L), sets the display start position S1 of the IP address to the 10th or 11th digit on the display 23. The cursor CS is fixed at the fifth digit, which is the editing position S2 (= variable M), and the portion after the last digit (15th digit) of the IP address is displayed as a blank.

  As a result, the MPU 20 of the wireless communication module 3 fixes the cursor CS of the display 23 to the fifth digit, so that it is possible to input a numerical value in advance in the blank portion of the sixth or seventh digit of the display 23 in advance. This can be avoided and intuitively recognized as the last digit of the IP address.

  By the way, if a negative result is obtained in step SP4, this indicates that the target of key input is not the right button 53. At this time, the MPU 20 of the wireless communication module 3 moves to the next step SP6.

  In step SP6, the MPU 20 of the wireless communication module 3 determines whether or not the key input target is the left button 54. If an affirmative result is obtained, the process proceeds to the next subroutine SRT7.

  As shown in FIG. 17, the MPU 20 of the wireless communication module 3 has the value of the number of digits C designated as the edit position of the IP address designated by the cursor CS before the key input to the left button 54 is performed in step SP41. It is determined whether the value of the number of digits of the IP address consisting of all 15 digits corresponds to any of “5”, “9”, or “13”.

  If a positive result is obtained here, this means that the value of the number of digits C of the IP address designated by the cursor CS before key input is “5”, “9” or “13”, that is, This indicates that the cursor CS is positioned at a period “.” Corresponding to a delimiter every three digits only by a single left shift process in response to a pressing operation on the left button 54. The MPU 20 moves to the next step SP42.

  In step SP42, the MPU 20 of the wireless communication module 3 uses the following equation for the value of the number of digits C of the IP address specified by the cursor CS before key input is performed.

Is used to calculate a new value of the number of digits C, and the process returns to the subroutine SRT2 of the routine RT1.

  On the other hand, if a negative result is obtained in step SP41, this means that the value of the number of digits C of the IP address designated by the cursor CS before key entry is “5”, “9” or “13”. In this case, the MPU 20 of the wireless communication module 3 proceeds to the next step SP43.

  In step SP43, the MPU 20 of the wireless communication module 3 determines whether or not the value of the number of digits C of the IP address designated by the cursor CS before key input is “1”.

  If an affirmative result is obtained here, this means that the value of the number of digits C of the IP address designated by the cursor CS is “1”, and the number of digits C of a smaller value is designated by the cursor CS. Therefore, the processing returns to the subroutine SRT2 of the routine RT1 without performing any processing.

  On the other hand, if a negative result is obtained in step SP43, the value of the number of digits C of the IP address designated by the cursor CS before key input is entered or edited when the key input is performed. This means that it is possible to move to the next left digit that can be performed. At this time, the MPU 20 of the wireless communication module 3 proceeds to the next step SP44.

  In step SP44, the MPU 20 of the wireless communication module 3 uses the following formula for the value of the number of digits C of the IP address specified by the cursor CS before key input is performed.

Is used to calculate a new value of the number of digits C, and the process returns to the subroutine SRT2 of the routine RT1.

  On the other hand, if a negative result is obtained in step SP6, this indicates that the key input target is neither the right button 53 nor the left button 54. At this time, the MPU 20 of the wireless communication module 3 performs the following operation. The process proceeds to step SP8.

  In step SP8, the MPU 20 of the wireless communication module 3 determines whether or not the key input target is the up button 55 or the down button 56. If an affirmative result is obtained, the process proceeds to the next step SP9, and a negative result is obtained. Is obtained, the process proceeds to step SP10.

  In step SP9, the MPU 20 of the wireless communication module 3 increases or decreases the value of the IP address designated by the cursor CS of the display 23 according to the pressing operation on the up button 55 or the down button 56, and returns to the subroutine SRT2.

  Here, when the MPU 20 of the wireless communication module 3 increases or decreases the numerical value in accordance with the pressing operation on the upper button 55 or the lower button 56, the cursor CS is positioned at the digit next to “.” Indicating a delimiter every three digits. In such a case, it is considered that the numerical value does not exceed “2” even when it is recognized that the pressing operation is performed on the upper button 55.

  Accordingly, the MPU 20 of the wireless communication module 3 can prevent the numerical value of every three digits of the IP address input by the user from exceeding “255” that can display 8 bits.

  In step SP10, the MPU 20 of the wireless communication module 3 determines whether or not the key input target is the right button 53, the left button 54, the upper button 55, or the lower button 56, and therefore is the enter key 52. To do.

  If a negative result is obtained here, this means that a key input other than the right button 53, the left button 54, the up button 55, the down button 56 or the enter key 52 has been performed. 3 MPU 20 returns to subroutine SRT2 and repeats the subsequent processing.

  On the other hand, if a positive result is obtained in step SP10, this means that the key input target is the enter key 52, that is, the input or editing of the IP address has been completed. At this time, the wireless communication module The MPU 20 of No. 3 recognizes the IP address displayed on the display 23 at this time as the final access destination, establishes a communication link based on the IP address, moves to the next step SP11, and ends the process.

(6) Operation and effect In the above configuration, the MPU 20 of the wireless communication module 3 has an edit data string with an IP address of 15 digits in total, whereas the display 23 has a display capability of 7 digits less than that. At a certain time, the display ranges AR1 to AR9 are sequentially scroll-displayed while shifting the 7-digit number string in accordance with the display capability of the display 23 in the IP address.

  At this time, the MPU 20 of the wireless communication module 3 does not place the cursor CS after the fifth digit of the display 23 (7-digit display), and always displays the cursor CS so as to leave an input field for three digits after the cursor CS. 23, the user can be guided to unconsciously input a numeric string of three digits after the cursor CS while sequentially moving the IP address display ranges AR1 to AR9 by scroll display.

  Therefore, when the MPU 20 of the wireless communication module 3 displays a period “.”, Which is a delimiter for every three digits, for example, in the fourth digit among the seven digits displayed on the display 23, the MPU 20 in the fifth digit to the seventh digit has 3 Since the input field for digits can be presented, when a user inputs an IP address number string, a one-digit or two-digit number string such as “1” or “10” can be input as it is. First, it can be sensibly recognized that it must be input as a three-digit number string such as “001” or “010”.

  In other words, the MPU 20 of the wireless communication module 3 wants to sequentially input IP addresses in which a plurality of recognizable 3-digit number string items are concatenated as 3-digit number strings. It is possible to avoid a situation where a digit or two-digit number string is input, and to prevent a wireless communication link from being established with an access destination unintended by the user.

  Further, when the MPU 20 of the wireless communication module 3 scrolls and displays the IP address display ranges AR1 to AR9 on the seven-digit display 23, the cursor CS moves from the first digit to the fifth digit. Is fixed to the fifth digit, and a blank is displayed after the 15th digit of the IP address, so that the user can intuitively recognize that it is not necessary to enter a numerical value after the 15th digit. Can do.

  According to the above configuration, the MPU 20 of the wireless communication module 3 shifts the IP address display ranges AR1 to AR9 by scroll display when the number of digits displayed on the display 23 is smaller than the total number of digits of the IP address to be input. However, by fixing and displaying the cursor CS at a position that prompts the MPU 20 to input a 3-digit number string that can be recognized, the number string with the required number of digits can be surely input, and an always accurate IP address Can be set by the user.
