[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a telephone, and more particularly to a telephone directory search function in a telephone.
[0002]
[Prior art]
In recent years, telephones that store telephone directory data in a built-in memory have become widespread.
Such a telephone has a built-in memory that stores and updates telephone book data consisting of a plurality of records whose items are the name of a communication destination such as a company name and a person name and the telephone number of the communication destination in accordance with a user operation. Has a registration function. In general, a telephone having a phone book registration function is such that when a user performs a specific operation related to phone book search, each item of a specific record is displayed on the display device portion of the telephone, or a specific record is selected. Or dialing a telephone number to make a call.
[0003]
Hereinafter, an example of user operation and telephone operation related to telephone directory search will be described with reference to FIG.
FIG. 2 is a diagram showing an overview of each key of the operation unit of the mobile phone.
First, the user presses a dedicated phone book key provided on the telephone. In addition, there is a conventional technique in which a dedicated phone book key is not required and is replaced by another operation method (see Patent Document 1).
[0004]
Upon detecting the pressing of the telephone directory key, the telephone displays a part of one record of the telephone directory data stored in the internal memory, for example, a name and a telephone number on the display device.
Next, when the user presses the down key 305 or the up key 304, the telephone displays the name and telephone number in the other one record on the display device.
[0005]
Therefore, the user can cause the display device to display a desired name and telephone number by pressing the down key 305 or the up key 304 many times.
The order of names displayed when the down key 305 is pressed many times is, for example, the order in which names are registered as phone book data. Further, in a telephone set in which a character string corresponding to the name of the communication destination, for example, a character string such as a reading name, is included in the telephone book data record, it is displayed when the down key 305 is pressed many times. In some cases, the names are arranged in the order of the Japanese syllabary or alphabetical order of the reading kana.
[0006]
According to such user operations and telephone operations, there is no particular problem when the number of registered phone book data is small. However, when the number of registered phone numbers is large, the key name is not displayed until the desired name and phone number are displayed. There is a problem in use that the number of presses increases and the operation becomes troublesome.
Therefore, in order to develop a telephone capable of registering a large number of records in pursuit of convenience, it is necessary to solve the above problems.
[0007]
In order to solve this problem, there has been proposed a telephone having a function of inputting an initial of a name of a communication destination and displaying a name having the initial and a corresponding telephone number (see Patent Document 2). . Such a telephone has a function for inputting initial characters by a combination of a key for specifying a row in the 50-sound table and a key for specifying a column in the 50-sound table, and a plurality of names having the same initial character are registered. Has a function to search and display the next name in the order of 50 tones by pressing a dedicated search key.
[0008]
According to this conventional telephone, there is a possibility that a specific name can be retrieved from a number of names registered as telephone directory data with a somewhat simple operation.

[0011]
[Problems to be solved by the invention]
However, according to the above-described conventional telephone, when a plurality of names including the same initials as the name desired by the user are registered as phone book data, the user usually operates a number of keys to start with the initials. The search key can be further searched and repeatedly pressed to obtain a display of a desired name and telephone number, and the operation is still complicated.
[0012]
Therefore, the present invention has been made in view of such problems, and an object of the present invention is to provide a telephone that allows a user to search for a desired name or the like from telephone directory data with a simpler operation.
[0013]
[Means for Solving the Problems]
The telephone according to the present invention includes a management unit that manages each of a plurality of character strings in order, a basic selection unit that selects one of the character strings managed by the management unit, and the basic selection unit When it is detected that the predetermined key has been pressed by the user after the selection by the user and the pressing continues for the first predetermined time or longer, the character string managed by the management unit A search selection means for searching for a character string starting with a letter different from the first letter of the last selected character string, and selecting a character string obtained as a search result; and selection by the basic selection means Later, when the user depresses the predetermined key and detects that the depressing is interrupted in less than the first predetermined time, it is managed by the managing means. A backward selection means for selecting a character string in a rank immediately after the last selected character string, and a user operation that requests execution of a predetermined process after selection by the basic selection means is detected. And an execution means for specifying the target of the predetermined process based on the last selected character string and executing the predetermined process.
[0014]
Here, the function of ordering and managing each of the plurality of character strings is realized, for example, by storing a plurality of character strings in a memory or the like and storing information that can determine the order of each character string.
With the above configuration, when the user keeps pressing a key such as a numeric key of the telephone for a predetermined time or more, for example, 1 second or more, and after the user presses the same key, the pressing is stopped within a predetermined time, for example, less than 1 second. In the former case, the character string is searched and selected from the ordered character string group by paying attention to the initial character, and in the latter case, the character string is selected according to the order in the character string group. Is realized. In the following, further explanation will be given assuming that the first key pressing mode is referred to as “long pressing” and the second key pressing mode is referred to as “short pressing”.
[0015]
For example, in the case where a large number of records including names, character strings indicating names of names, telephone numbers, etc. are recorded as telephone directory data, the telephone enters a mode for searching telephone directory data, When all or a part of the book data is managed by arranging a large number of character strings indicating the titles of names, in alphabetical order, this telephone will manage when the user presses and holds a numeric key. In the string group, the character string with a different initial letter is skipped and selected, and each time the user presses the same numeric key, the next string is selected. When the user presses the same numeric key for a long time, the character string is selected by skipping to the next character string with a different initial letter. Therefore, the user does not need to search for a numeric key to be pressed each time it is pressed, and can easily select a desired character string simply by changing how the same numeric key is pressed. It should be noted that the user can cause the telephone to perform a calling process with the telephone number corresponding to the character string as a call destination by performing a predetermined operation with the character string selected.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a mobile phone according to an embodiment of the present invention will be described in detail with reference to the drawings.
<Configuration>
FIG. 1 is a block diagram showing a configuration of a mobile phone according to an embodiment of the present invention.
[0017]
As shown in the figure, the mobile phone 10 includes a radio unit 11, a modem 12, a TDMA (Time Division Multiple Access) processing unit 13, a D / A / A / D conversion unit 14, an audio processing unit 15, a speaker 16, and a microphone. 17, a storage unit 18, an operation unit 19, a display unit 20, and a control unit 21.
Here, the radio unit 11 receives a PLL (Phase Locked Loop) frequency synthesizer unit 11b that generates a local oscillation frequency signal that determines a carrier frequency to be transmitted and received, and a radio frequency (RF) signal that is input from an antenna at the time of reception. An RF / IF unit 11a that converts an intermediate frequency (IF) signal into a baseband signal and an RF / IF unit 11c that converts the baseband signal to a high frequency during transmission are configured.
[0018]
The modem 12 is a modem that performs modulation and demodulation by π / 4 shift QPSK (Quadrature Phase Shift Keying) or the like between the wireless unit 11 and the TDMA processing unit 13.
The TDMA processing unit 13 divides one baseband signal into 8 time slots per 5 milliseconds (ms), and allocates 4 slots in the upstream and 4 slots in the downstream, thereby time-division multiplexing 4 channels in both directions. Has the function of
[0019]

[0020]
The display unit 20 is a liquid crystal display, and is used for displaying a part of the phone book data under the control of the control unit 21.
The operation unit 19 has a plurality of keys for accepting user operations. When the user operates the keys, information relating to when the key is pressed and when the key is stopped, that is, when the key is released. It functions as an input interface that notifies the control unit 21 of which key is the pressed key.
[0021]
FIG. 2 is a diagram showing an overview of each key of the operation unit of the mobile phone.
As shown in the figure, the operation unit 19 includes a call key 301 used for making or receiving a call, an end key 302 used for instructing the end of processing, and basically display contents of the display unit 20. An upward key 304 and a downward key 305 that are used to advance a part or all of the information upward or downward, and a numeric keypad 310 that is basically a set of numeric keys used for inputting telephone numbers and characters. Have Here, the numeric keypad 310 is composed of numeric keys to which any number or symbol of “0” to “9”, “*”, and “#” is assigned.
[0022]
Similar to the numeric keypad of the conventional mobile phone, most numeric keys in the numeric keypad 310 are assigned kana and English letters (alphabet) in addition to numbers. For example, in the numeric key 311 in which “2” is written, “ka” and “ABC” are written in addition to “2”, and the user presses the numeric key 311 to “2”. In addition to each character of “ka line” (“ka”, “ki”, “ku”, “ke”, “ko”) and “A”, “a”, “B”, “B”, “C” and “c” can be specified or entered.
[0023]
The numeric keys constituting the numeric keypad 310 are also used for instructing to start searching for the phone book data, for instructing to skip the phone book data, and for instructing to select the next one of the phone book data. Used.
The control unit 21 is configured by a microcomputer incorporating a ROM and a RAM, and controls the mobile phone 10 by executing various programs in the ROM. For example, based on information notified from the operation unit 19 The processing corresponding to the key operation by the user is performed. Similar to a conventional telephone, the control unit 21 receives input of phone book data from the user via the operation unit 19 and performs processing for storing the phone book data in the storage unit 18.
[0024]
Note that the control unit 21 measures the key press time using a time counter, and when it is received that the numeric key is pressed for 1 second or longer (long press) via the operation unit 19, the phone book search process Execute. This telephone directory search process will be described in detail later.
<Data>
FIG. 3 is a diagram showing a configuration and example contents of the phone book data stored in the storage unit 18.
[0025]
This phone book data is formed as a result of the control unit 21 of the mobile phone 10 receiving new inputs or update inputs of the respective components of the phone book data from the user via the operation unit 19 and storing them in the storage unit 18 at any time. The
As shown in the figure, the telephone directory data 410 is table data as a collection of records including a registration number 411, a name 412, a nominal character string 413, and a telephone number 414. In the example of the figure, one line shows one phone book record.
[0026]
Here, the registration number 411 is a number that is added by the control unit 21 in increments of 001, 002,.
Further, the name 412, the nominal character string 413, and the telephone number 414 are information input by the user, the name 412 is the name or company name of the other party making the call, and the nominal character string 413 is the nominal name of the other party. For example, it is a reading pseudonym corresponding to the name 412, and the telephone number 414 is the telephone number of the other party.
[0027]
For example, in the record of the registration number “001” illustrated in FIG. 3, the name of the party to call is “Hiro Kubo”, the reading character name is “Kubo Hiroshi”, and the phone number is “090-1234-XXXX”.
FIG. 4 is a diagram showing a configuration and an example of contents of a search nominal character string list formed by the control unit 21.
[0028]
This search name string list is formed in the RAM by the control unit 21 of the mobile phone 10 during the phone book search process.
As shown in the figure, the retrieval nominal character string list 420 extracts the registration number 421 and the nominal character string 422 for some records in the telephone directory data 420 so that the nominal character string 422 is in the order of 50 notes. As a result of being sorted into
[0029]
In the example shown in the figure, a search nominal character string list corresponding to the numeric key 311 of “2” is shown. In this nominal symbol string for search, “2” is assigned to the numeric key 311. A nominal character string starting with each letter of “Ka Line” is arranged in the order of the Japanese syllabary.
<Operation>
Hereinafter, the operation of the mobile phone 10 having the above-described configuration and handling the above-described telephone directory data will be described.
[0030]
FIG. 5 is a flowchart showing an outline of processing for key pressing of the mobile phone 10.
The control unit 21 of the mobile phone 10 determines whether or not the numeric key is pressed by the user via the operation unit 19 (step S601). If the numeric key is not pressed, the control unit 21 is the same as the conventional mobile phone. General processing is performed (step S602), and the process returns to the determination of step S601. In step S602, for example, processing related to reception of a control signal from a radio base station, processing for performing location registration as necessary, various processing corresponding to pressing of a key other than a numeric key, and the like are performed.
[0031]
When it is determined in step S601 that the numeric key is pressed by the user, the control unit 21 determines whether the numeric key is pressed long or short (step S603). Long press means that the key is not released even if a predetermined time elapses from the start of pressing, that is, the press continues for a predetermined time or more, and short press is released before the predetermined time elapses from the start of pressing. Means. In this embodiment, the predetermined time is 1 second.
[0032]
That is, the control unit 21 generates either an event that the pressing is not stopped even after one second has elapsed from the start of pressing, or an event that the pressing has been stopped before one second has elapsed from the start of pressing. Whether or not the key has been pressed is determined according to which event has occurred (step S603).
If it is determined in step S603 that the numeric key has not been pressed for a long time, that is, if it is determined that the numeric key has been pressed for a short time, the control unit 21 determines whether the numeric key corresponding to the numeric key or Performs processing to accept characters as input values. If the user presses the call key 301 after step S604 and step S602, for example, the user inputs a numerical group by short pressing each numerical key, the control unit 21 sets the telephone number formed by the input numerical group. Each part of the mobile phone 10 is controlled so as to make a call by dialing.
[0033]
If it is determined in step S603 that the numeric key has been pressed for a long time, the control unit 21 executes a telephone directory search process (step S605), and thereafter returns to the determination in step S601.
FIG. 6 is a flowchart showing the telephone directory search process.
When detecting the long press of the numeric key, the control unit 21 generates a search character string list corresponding to the long-pressed numeric key in the RAM (step S606). For example, the numeric key 311 of “2” includes “ka”, “ki”, “ku”, “ke”, “ko”, “A”, “a”, “B”, “b”, “C” ”,“ C ”, and“ 2 ”are assigned, so when the numeric key 311 is pressed for a long time, the control unit 21 stores the phone book data stored in the storage unit 18 (see FIG. 3). From the above, the initial character of the nominal character string is “ka”, “ki”, “ku”, “ke”, “ko”, “A”, “a”, “B”, “b”, “C”, A character string list for search as illustrated in FIG. 4 is generated in the RAM by arranging the characters “c” and “2” in this character order.
[0034]
Subsequently, the control unit 21 selects the first call character string in the search call character string list (step S607), specifies a name corresponding to the selected call character string, and displays the name on the display unit 20. (Step S608). That is, the control unit 21 obtains a registration number 421 corresponding to the selected nominal character string 422 from the retrieval nominal character string list, and has the same registration number in the phone book data 410 based on the registered number 421. The phone book record is specified and the name 412 in the phone book record is displayed on the display unit 20.
[0035]
Here, it is assumed that the display screen format by the display unit 20 can simultaneously display four names. Therefore, in step S608, the control unit 21 selects names corresponding to all four nominal character strings including three nominal character strings that follow the nominal character string selected in the nominal character string list for search. The names are displayed on the display unit 20 in order from the top, and the names corresponding to the selected nominal character strings are highlighted. In addition, the display part 20 displays a radio wave reception state, a battery state, etc. other than the name for four cases.
[0036]
FIG. 7 is a diagram illustrating a state of screen transition according to a user operation.
A screen 501 is the content of the screen immediately after the end of step S608. Subsequent to step S608, the control unit 21 determines whether or not the number key that has been determined to be long pressed has been in a state of continuing long press (step S609). In other words, the control unit 21 determines that the number key has been continuously pressed even after one second has elapsed from the time when it has already been determined that a long press has been made or has been in a long press continuing state, and the time at which it has already been determined. The process waits until one of the events that the pressing is stopped before the elapse of one second from the beginning, and determines whether or not the long pressing is continued depending on which event has occurred (step S609). ).
[0037]
If it is determined in step S609 that the numeric key is not in the state of long press continuation, the control unit 21 determines whether or not the call key 301 is pressed (step S612), and determines that the call key 301 is pressed. If so, each part of the mobile phone 10 is controlled to dial and make a call using the telephone number corresponding to the currently selected nominal character string (step S613), and the telephone directory search process is terminated.
[0038]
If it is determined in step S612 that the call key 301 has not been pressed, the control unit 21 determines whether or not the end key 302 has been pressed (step S614), and determines that the end key 302 has been pressed. In this case, the phone book search process is terminated. If it is determined in step S614 that the end key 302 has not been pressed, the control unit 21 determines whether or not the number key has been pressed (step S615). If the number key has not been pressed, the call key The process returns to the determination step S612 for pressing the button. Note that the numeric key to be determined in step S615 is a long-pressed numeric key that triggered the phone book search process (step S605).
[0039]
If it is determined in step S615 that the numeric key has been pressed, the control unit 21 further determines whether the numeric key has been pressed long or short (step S616).
That is, the control unit 21 generates either an event that the pressing is not stopped even after one second has elapsed from the start of pressing, or an event that the pressing has been stopped before one second has elapsed from the start of pressing. Depending on which event has occurred, it is determined whether or not the key has been pressed for a long time (step S616). If it is determined that the key has not been pressed for a long time, it has already been selected from the search name string list. The name character string next to the name character string is selected (step S617), and the name in the telephone directory data corresponding to the selected name character string is displayed on the display unit 20 (step S618).
[0040]
Note that, as described above, four items can be displayed on the display unit 20, so the control unit 21 manages the contents of the four items displayed on the display unit 20, and in step S618, newly When displaying the name corresponding to the selected nominal character string, the display content is determined as follows.
That is, when the name corresponding to the newly selected nominal character string is already displayed on the display unit 20, the four displayed names are left unchanged and the newly selected nominal character string is responded. Change only the highlighting target so that the name to be highlighted is highlighted. If the name corresponding to the newly selected nominal character string is not displayed on the display unit 20, the display content is scrolled up by one item, and the newly selected nominal character string is responded to the lowest level. The name to be displayed is newly displayed, and the reverse display target is changed so that the name is displayed in reverse video.
[0041]
For example, assuming that the phone book data has the contents illustrated in FIG. 3 and the search character string list has the contents illustrated in FIG. 4, the screen 501 shown in FIG. If the user presses the number key 311 for a short time, the control unit 21 performs the processes of step S615 (yes), step S616 (no), step S617, and step S618, and as a result, the screen 502 is displayed on the display unit. Similarly, if the user further presses the number key 311, the screen 503 is displayed. If the user further presses the number key 311, the screen 504 is displayed. If the numeric key 311 is further pressed briefly, the screen 505 is displayed. If the user further presses the numeric key 311, the screen 506 is displayed.
[0042]
If it is determined in step S609 that the numeric key is in the state of long press continuation, the control unit 21 uses a nominal character string having an initial character different from the character string currently selected from the nominal character string list for search. Are searched in accordance with the list order, and a nominal character string as a search result is selected (step S610), the name in the telephone directory data corresponding to the selected nominal character string is displayed on the display unit 20 (step S611), and again. The process returns to the determination step S609 as to whether or not the long press is continued.
[0043]
Assuming the search character string list having the contents illustrated in FIG. 4, if “Kakimoto Shiro” is currently selected and the long press of the numeric key 311 is continued, By S610, the nominal character string “Kikugawa Hatsuko” having an initial of “ki” different from “ka”, which is an initial of “kakimoto shiro”, is selected.
[0044]
Note that this is not included in the example of FIG. 4 in order to simplify the description, but “ka”, “ki”, “ku”, “ke”, “ko” ”,“ A ”,“ a ”,“ B ”,“ b ”,“ C ”,“ c ”, and“ 2 ”. In addition, after the last name string in the search name string list, the search is performed assuming that the first name string in the list is connected. For example, when "Konishima Sako" is currently selected When the numeric key 311 is pressed for a long time, “Kakimoto Shiro” at the top of the list having an initial that is different from “Ko”, which is the initial of “Konishima Sako”, is selected in step S610. become.
[0045]
In step S611, when a name corresponding to the newly selected nominal character string is displayed, the display content is determined as follows.
That is, when the name corresponding to the newly selected nominal character string is already displayed on the display unit 20, the four displayed names are left unchanged and the newly selected nominal character string is responded. Change only the highlighting target so that the name to be highlighted is highlighted. Further, when the name corresponding to the newly selected nominal character string is not displayed on the display unit 20, the nominal character strings for three items following the newly selected nominal character string in the retrieval nominal character string list. The names corresponding to each of the four nominal character strings including the characters are displayed in order from the top on the display unit 20, and only the names corresponding to the selected nominal character strings are highlighted.
[0046]
FIG. 8 is a diagram illustrating a state of screen transition according to a user operation.
Here, assuming that the phone book data has the contents illustrated in FIG. 3 and the search character string list has the contents illustrated in FIG. 4, an operation performed before the user calls “Emi Kuroda”. The operation of the mobile phone and the screen transition will be described.
When the user presses the numeric key 311 for a long time, the control unit 21 sequentially performs the processes of step S601 (yes), step S603 (yes), step S606, step S607, and step S608, and as a result, a screen 511 illustrated in FIG. Is displayed (step S608), and in this state, if the user continues to press the numeric key 311 for 1 second or more without releasing it, the control unit 21 performs steps S609 (yes), S610, and S611. Processing is performed in order, and as a result, a screen 512 is displayed on the display unit 20.
[0047]
Furthermore, if the user continues to press the numeric key 311 for one second or more without releasing it, the control unit 21 performs the processing of step S609 (yes), step S610, and step S611 in order, and as a result, A screen 513 is displayed on the display unit 20.
After that, if the user releases the numeric key 311 once less than 1 second has elapsed, that is, ends the long press continuation state, and then presses the numeric key 311 for a short time, the control unit 21 performs step S609 (no). , Step S612 (no), Step S614 (no), Step S615 (yes), Step S616 (no), Step S617, Step S618 are sequentially performed, and as a result, the screen 514 is displayed on the display unit 20. .
[0048]
After that, if the user again presses the numeric key 311 again, the control unit 21 performs step S612 (no), step S614 (no), step S615 (yes), step S616 (no), step S617, step The process of S618 is performed in order, and as a result, the nominal character string “Emi Kuroda” is selected, and a screen 515 formed by inverting the corresponding name “Emi Kuroda” is displayed on the display unit 20. .
[0049]
Thereafter, when the user presses the call key 301, the control unit 21 performs the processing of step S612 (yes) and step S613 in order, and the telephone corresponding to the last selected character string “Kuroda Emi”. Control to dial the number "□□□-○○○○-△△△△".
After all, when the phone book data is as shown in FIG. 3, when the user wants to call the person named “Emi Kuroda” by operating the mobile phone 10, “2”. The numeric key 311 is continuously pressed and held for a long time with the finger, and the name key 311 that has been long-pressed is released from the finger when the name “Kaeda Atsushi” starting with the letter “ku” is displayed on the liquid crystal display. Thus, the desired “Emi Kuroda” can be quickly displayed on the liquid crystal display by a simple operation of simply pressing the number key 311 twice, and when the call key 301 is further pressed, “Emi Kuroda” is immediately called. You will be able to call the person with the name.
<Supplement>
The telephone according to the present invention has been described based on the mobile phone 10 as an embodiment. However, the mobile phone 10 can be modified, and the present invention is not limited to the above-described embodiment. . That is,
(1) Although the mobile phone 10 is shown in the embodiment, the phone according to the present invention may be any terminal that can make a phone call, for example, a home phone connected to a public network by wire, It may be a personal handyphone system (PHS) portable device.
(2) The telephone directory data shown in the embodiment may include an electronic mail address in addition to a telephone number in association with a name and a nominal character string. Further, the mobile phone 10 may transmit a message separately input by the user with the e-mail address corresponding to the nominal character string selected by the telephone directory search process as a destination.
(3) In the embodiment, the mobile phone 10 performs a phone book search process in response to a long press of a numeric key by the user, and displays four names registered as phone book data at a time on the liquid crystal display screen. However, the number of items displayed on one screen is not limited to four, and only one item may be displayed or seven items may be displayed because of the size of the liquid crystal display. In the telephone directory search process, a telephone number, an e-mail address, and other information may be displayed on the liquid crystal display in addition to the name. In the embodiment, the mobile phone 10 displays a name corresponding to the selected nominal character string on the liquid crystal display. However, a method for transmitting information related to the nominal character string to the user is to display on the liquid crystal display. There is no limitation, and the nominal character string may be read out by voice using a technique related to voice synthesis.
(4) In the embodiment, when the numeric key is kept pressed for a long time, the selected character string from the nominal character string on the search nominal character string list is different from the selected nominal character string. The search character string is searched and selected one after another. For example, “ka”, “ki”, “ku”, “ke”, “ko” and the initials are selected in advance. This is realized by storing a list of initials in which the initials are ordered and collating the stored initials with the initials of the nominal character string in the nominal character string list for search according to the order of the initial character list. It is good as well. In other words, if the initial character of the currently selected nominal character string is “ka”, the selected nominal character is matched with “ki” positioned next to “ka” in the initial character list. Search until the matching target matches backward from the next nominal character string in the column, and if it does not match, search is performed by searching for “ku” next to “ki”. Also good.
[0050]
Note that the mobile phone 10 repeatedly executes a process of searching for and selecting a nominal character string having an initial that is different from the currently selected nominal character string when the numeric key is continuously pressed. In the search character string list, the last call character string is followed by the first call character string in the list, that is, the list is handled as if it is looping. It is good. Thereby, for example, in order to search for a name whose initial name is “ku”, the user starts long-pressing the “2” numeric key 311 corresponding to the “ka” line, and then the user When a name with the initial letter “K” displayed on the liquid crystal display, the long press stop, that is, release of the numeric key 311 failed once in a timely manner, and the initial letter “ Even after the name “Ke” is displayed on the liquid crystal display, the user can display the name whose initial acronym is “ku” again on the liquid crystal display by pressing and holding for a while. If the long press is stopped at that time, a desired name can be displayed on the mobile phone and a telephone number corresponding to the name can be dialed with a small number of operations. (5) In the embodiment, the mobile phone 10 performs the phone book search process (see FIG. 6) due to the long press of the numeric key by the user. However, the mobile phone is for searching the phone book other than the numeric key by the user. It is also possible to start the phone book search process upon receiving a press of a dedicated key or the like. In this case, in step S606, a search nominal character string list is generated in which all nominal character strings constituting the telephone directory data are arranged in a fixed order such as in the order of the Japanese syllabary or alphabetical order.
[0051]
In addition, after starting the telephone directory search process, pressing of the down key 305 as well as the numeric keys may be handled in the same manner. For example, when the user first presses and holds the number key 311 of “2”, the cellular phone 10 starts the phone book search process, and if the user presses the down key 305 after that, it is changed to “2”. The telephone directory search process may be executed by treating it as equivalent to pressing the numeric key 311.
[0052]
Further, when the user presses the up key 304, if it is a short press, the name character string immediately before the currently selected character string in the name character string list for search. If a long press or long press continuation is selected, a search is performed in the reverse direction of the list for a call character string having a different initial character from the currently selected call character string, and the initial character that is detected first is different. It is also possible to newly select a nominal character string. When searching in the reverse direction of this list, the order in the list is the most of the initial character strings that have the same initial character as the different initial character strings that were first detected in the reverse search. It is good also as selecting the name character string which is ahead. In such a case, for example, when the cellular phone 10 is currently selecting and displaying a nominal character string with the initial letter “ku”, the up arrow key 304 is long pressed or continued to be pressed by the user. For example, the cellular phone 10 newly selects and displays a first-named call character string among the call character strings whose initials are “ki” in the search-use called character string list.
(6) In the embodiment, the time of 1 second is used as each determination criterion in the determination of whether the long press or the short press, or whether the long press continues after the previous long press determination. The time is not limited to 1 second, and for example, it may be 2 seconds for the criteria for determining whether or not long presses and 1.5 seconds for the criteria for determining whether or not to continue long presses. Assuming that 1.5 seconds is adopted as a criterion for determining whether or not to continue long press, if the user continues long press for a sufficiently long time, the display state of the name and the like displayed on the liquid crystal display is updated every 1.5 seconds. Will be.
(7) In the embodiment, when the name corresponding to the newly selected nominal character string is already displayed on the display unit 20 in step S611 and step S618, the four displayed names are left as they are. In this case, only the highlight display target is changed so that the name corresponding to the newly selected nominal character string is highlighted. For example, the name corresponding to the newly selected nominal character string is displayed on the display unit. It is good also as scrolling so that it may be displayed on the top line in 20, and it is scrolled so that the name corresponding to the newly selected nominal character string may be displayed at a position near the center of the display unit 20 instead of the top line. It is good as well.
(8) At the recording or updating stage of the phone book data shown in the embodiment, the mobile phone 10 accepts the input of the item name in the phone book record by the user as a result of the so-called kana-kanji conversion process, The phone book record may be stored in the storage unit 18 using the kana character string input by the user before the kana-kanji conversion process as a nominal character string corresponding to the name in the phone book record.
(9) In the embodiment, the search nominal character string list corresponding to the numeric key long pressed in the telephone directory search process is generated (see FIG. 6), but the search nominal character string corresponding to each numeric key is generated. The list may be generated or updated at the time of registration or update of the phone book data according to the user operation and stored in the non-volatile memory. Also, the search name string in the RAM immediately after the mobile phone is turned on. As the generation of the list, the search character string list in the RAM may be updated when the telephone directory data is registered or updated. For a certain numeric key, any character assigned to the numeric key, for example, “1” key, “A”, “I”, “U”, “E”, “O”, And a search character string list corresponding to a list of nominal character strings in all phonebook data whose initials are either “1” or “1”.
(10) The order of the nominal character strings in the search nominal character string list shown in the embodiment may be in the order of kana characters, alphabets, and numbers, or may be in another order. Also, a flag for deciding which of the kana characters and the alphabet is to be ranked first is stored in the telephone, the flag can be updated, and the order of the naming character string is determined according to the flag for searching. A nominal character string list may be generated. Note that the telephone may update the flag when making a call in accordance with whether the initial character of the nominal character string relating to the other party making the call is a kana character or an alphabet.
(11) In the embodiment, the nominal character string and the registration number are associated with each other in the retrieval nominal character string list. However, in the retrieval nominal character string list, the nominal character string and the nominal character string are displayed. It is sufficient that it is associated with some information that can specify the location of the phone book record including the. In other words, the search name string list may be configured so that the phone book record can be specified from the selected name string, and the names and the like that are constituent elements thereof can be specified.
(12) A program for causing the CPU to execute the telephone directory search process (see FIG. 6) shown in the embodiment can be recorded on a recording medium or distributed and distributed via various communication paths. Examples of such a recording medium include an IC card, an optical disk, a flexible disk, and a ROM. The distributed and distributed program is used by being stored in a memory or the like that can be read by the CPU in the telephone, and the CPU executes the program to search for the phone book as shown in the embodiment. Function is realized.
[0053]
【The invention's effect】
The telephone according to the present invention includes a management unit that manages each of a plurality of character strings in order, a basic selection unit that selects one of the character strings managed by the management unit, and the basic selection unit When it is detected that the predetermined key has been pressed by the user after the selection by the user and the pressing continues for the first predetermined time or longer, the character string managed by the management unit A search selection means for searching for a character string starting with a letter different from the first letter of the last selected character string, and selecting a character string obtained as a search result; and selection by the basic selection means Later, when the user depresses the predetermined key and detects that the depressing is interrupted in less than the first predetermined time, it is managed by the managing means. A backward selection means for selecting a character string in a rank immediately after the last selected character string, and a user operation that requests execution of a predetermined process after selection by the basic selection means is detected. And an execution means for specifying the target of the predetermined process based on the last selected character string and executing the predetermined process.
[0054]
As a result, when the user keeps pressing the key such as the numeric key of the telephone for a predetermined time or longer, for example, 1 second or longer, the user stops pressing the same key for a predetermined time, for example, less than 1 second after the user presses the same key. In the former case, the character string is searched and selected from the ordered character string group by paying attention to the initial character, and in the latter case, the character string is selected according to the order in the character string group. Is realized.
[0055]
For example, in the case where a large number of records including names, character strings indicating names of names, telephone numbers, etc. are recorded as telephone directory data, the telephone enters a mode for searching telephone directory data, When all or a part of the book data is managed by arranging a large number of character strings indicating the titles of names, in alphabetical order, this telephone will manage when the user presses and holds a numeric key. In the string group, the character string with a different initial letter is skipped and selected, and each time the user presses the same numeric key, the next string is selected. When the user presses the same numeric key for a long time, the character string is selected by skipping to the next character string with a different initial letter. Therefore, the user does not need to search for a numeric key to be pressed each time it is pressed, and can easily select a desired character string simply by changing how the same numeric key is pressed. It should be noted that the user can cause the telephone to perform a calling process with the telephone number corresponding to the character string as a call destination by performing a predetermined operation with the character string selected.
[0056]
Here, when the search selection means detects that pressing of the predetermined key continues for the first predetermined time or longer, the search selection means finally selects the character string managed by the management means. A character string having a first character different from the first character of the character string as a first character is searched, a character string obtained as a result of the search is selected, and pressing of the predetermined key is longer than the first predetermined time. When it is detected that it has continued for a second predetermined time or more, a character string starting with a second character different from the first character is searched from the character strings managed by the management means. The character string obtained as a search result may be selected.
[0057]
As a result, the user continues to press the numeric key for a longer time after a search and selection of the initial character string different from the selected character string is performed when the user presses the numeric key for a long time. Then, another initial character string is searched and selected. Accordingly, the user can determine the number of times to repeat the search by adjusting the time for which the numeric key is continuously pressed.
[0058]
Further, the management means manages each of the plurality of character strings being managed in association with individual display data, and the telephone is further selected every time a character string is selected. Display means for displaying individual display data corresponding to the character string may be provided.
As a result, when the user continues to press the numeric key for a long time, for example, among the nominal character strings for the names registered in the telephone directory, the nominal character string whose initial character is different from the currently selected nominal character string. Each time a skip search and selection is performed, a name corresponding to the selected nominal character string is displayed on the liquid crystal display of the telephone. Therefore, the user can determine the timing of stopping the pressing of the numeric key, that is, the timing of releasing the numeric key while viewing the displayed name.
[0059]
Further, the management means ranks the plurality of character strings so that character strings having the same initial letter are consecutive, and the search selection means is configured to press the predetermined key when the predetermined key is pressed. When it is detected that it continues for more than a time, it is a character string of the rank behind the character string selected last from among the character strings managed by the management means, and finally Search for a character string with the first rank in a character string starting with a first character different from the first character of the selected character string, and pressing the predetermined key continues for the second predetermined time or longer. When the character string is detected, the character string managed by the management unit is a character string that is ranked behind the character string having the first character as an initial character and is different from the first character. The first rank in a string starting with 2 letters It is also possible to search for the string.
[0060]
Thus, for example, the user can use the numeric keypad until a name corresponding to a reading kana that has the same initial as the reading kana such as one name of a desired phone book is displayed on the liquid crystal display or the like. By pressing the key for a long time and obtaining the display, the user can display the desired name on the liquid crystal display etc. with relatively few finger movements by pressing the same numeric key several times. become.
[0061]
Further, the search selection means sets the last selected character string as a search start position, and detects that the predetermined key has been pressed after detecting that the predetermined key has been pressed for the first predetermined time or longer. Searching the plurality of character strings managed by the management means backward with respect to the rank, with the character string having a different initial character from the character string of the search start position as the search target, with the number of searches corresponding to the duration time The search target character string detected first is determined as the search start position in the next search, and the procedure of selecting the character string is repeated, and the search target character string is behind the search start position in the search. If there is no character string, it is assumed that the character string of the first rank among all the character strings managed by the management means is connected behind the character string of the last rank, and the search is executed. Also to do There.
[0062]
As a result, for example, when the user continues to press the number key with a finger and the finger should be released from the number key at the timing when the target name is displayed on the liquid crystal display, the timing is missed and another name cannot be obtained. Even if it is displayed on the liquid crystal display, if the user continues to press the button, the target name is displayed again, and the finger can be released from the numeric key at that time. .
[0063]
The telephone further includes a reverse search selection means for searching for a character string in a direction opposite to that of the search selection means, and a user presses a specific key different from the predetermined key after selection by the basic selection means. And, when it is detected that the pressing is interrupted in less than the first predetermined time, among the character strings managed by the management means, the character string in the rank immediately before the last selected character string Forward selection means for selecting, the reverse search selection means, after the selection by the basic selection means, the user presses the specific key, and the pressing continues for a first predetermined time or more Of the character strings managed by the management means, the character string is ranked in front of the character string selected last and is selected last. The character string of the first rank is searched for in the character string starting with the third character different from the initial character of the selected character string, the character string obtained as the search result is selected, and the specific key is pressed When it is detected that it has continued for the second predetermined time or longer, a character string in a rank higher than a character string having the third character as an initial character among the character strings managed by the management means The character string obtained as a search result may be selected by searching the character string having the first rank among the character strings having the fourth character different from the third character as the initial character.
[0064]
Thereby, the user can easily execute the search for the ordered character string group according to the order and the search in the reverse order by selecting and pressing one of the two keys. Become.
In addition, each time a character string is selected, the display means is selected last among the character strings managed by the management means together with the individual display data corresponding to the character string selected last. Display individual data corresponding to each of a predetermined number of character strings whose ranks are consecutive in the character string is also displayed, and the search selection unit detects that the predetermined key has been pressed for the second predetermined time or longer. In this case, only when the number of character strings starting with the first character among the character strings managed by the management means is equal to or greater than a specific number greater than the predetermined number, the second Instead of searching the character string of the first rank among the character strings having the first letter as the first character, the character string having the specified number of ranks is searched from the character string of the first rank having the first character as the first letter. It is good to do
[0065]
As a result, when the user continues to press the numeric key for a long time, the telephone moves the selected position to each boundary determined by different initial letters of the character strings in the ordered character strings. In addition, if the number of character strings having the same initial character is greater than a certain threshold value, the selected position is also moved to each boundary determined with a certain number of intervals in the character string order. For example, if the fixed number related to the interval is 4, and there are 15 character strings having the initial letter “KI”, if the user continues to press the numeric key, the character string having the initial letter “KI” Among them, the first one, the fifth one, the ninth one, and the thirteenth one are sequentially selected in this order. Therefore, even when the number of character strings having the same initial letter is large, the user can display one name or the like of a desired phone book by relatively few finger movements, and The telephone can be instructed to make a call to the other party.
[0066]
The predetermined key is a numeric key for inputting a telephone number, and the basic selection means performs the selection when it is detected that the user continues to press the predetermined key for a third predetermined time or longer. It is good.
Thus, the user can cause the telephone to select the first character string in the character string group ordered corresponding to the numeric key by pressing and holding one numeric key, and further presses the numeric key. If you leave it alone, you can let the phone search for and select a character string that has a different initial character from the selected character string, and by pressing the number key briefly, the character string next to the last selected character string can be selected. Can be selected. Accordingly, the user can change the way of pressing one numeric key, and can easily select a desired character string on the telephone and display information such as a name corresponding to the character string with a few finger movements. Will be able to.
[0067]
The telephone includes storage means for storing a plurality of records including items of a communication destination name, a communication destination telephone number, and a search character string, and the management means includes a search included in the storage means. Among the character strings for use, a plurality of characters assigned in advance to the predetermined key are all managed in order, and the management means associates them with the character strings for each search. The individual display data to be managed may be the name of the communication destination in the same record as the search character string.
[0068]
As a result, the user can easily press a numeric key to select a character assigned to the numeric key in advance, for example, “ka”, “ki”, “ku”, “ke” if the numeric key is “2”. , “Ko”, “A”, “a”, “B”, “b”, “C”, “c”, and “2”, the communication destinations associated with the initial character strings Can be displayed on the telephone.
[0069]
In addition, the telephone further includes a determination unit that determines whether to give priority to an English character or a kana, and the management unit uses an English character as an initial if the determination by the determination unit has priority on the English character. If the character string is placed in the order preceding the character string with the kana character as the initial character and the decision is given priority to the kana character, the character string with the kana character as the initial character is preceded by the character string with the initial character as the initial character. It is good also as ordering each character string so that it may become the order of.
[0070]
This allows the telephone to set the flag or the like in order to determine which of the character string whose initial letter is a kana character or the character string whose initial letter is an English character based on, for example, a flag. By changing it, it becomes possible to change the appearance of the character strings that are sequentially displayed based on the pressing of the numeric keys. Note that the character string with the first rank can be searched quickly.
[0071]
Further, the management means may manage the character strings to be managed in an alphabetical order for those whose initials are kana characters.
This allows users who know Japanese, such as “ka”, “ki”, “ku”, “ke”, “ko”, etc., in response to the user continuing to press the numeric key for a long time. Are selected in order of easy-to-understand 50-note order.
[0072]
In addition, the telephone includes storage means for storing a plurality of records including items of a name of a communication destination, a telephone number of the communication destination and a search character string for the name, and the management means includes the storage means Among the search character strings included in the list, all the character strings starting with one of a plurality of characters assigned in advance to the predetermined key are managed in order, and the phone further selects the character string. Each time a character string selected last and a name included in the same record are displayed, the execution means includes a telephone number included in the same record as the last selected character string. May be specified as the target of the predetermined process, and a call using the target may be executed as the predetermined process.
[0073]
As a result, the user causes the telephone to select a character string by a simple operation of pressing a numeric key, and dials a telephone number corresponding to the selected character string to the telephone by a predetermined operation such as pressing a call key. To be able to. That is, the user can search the phone book data and make a call to a desired party with a simple operation.
