BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device suitable for use in a portable telephone or the like. More specifically, the first and second operators are used to search for desired data from a data storage unit in which a plurality of data groups each including one or a plurality of data are stored. The present invention relates to a communication terminal device in which the number of operators is reduced to reduce the size and cost of the device.

[0002]

2. Description of the Related Art In recent years, some communication terminal devices, for example, simple portable telephones (PHS: Personal Handyphone System) and portable telephones have a telephone directory function. The telephone directory function means that telephone directory data including data such as telephone numbers and names are stored in data storage means, and when a call is made, a call is made using the telephone number data included in the retrieved predetermined telephone directory data. It is a function that can make a call.

Conventionally, as a method of searching for desired telephone directory data from a plurality of telephone directory data stored in the above-mentioned data storage means, a method using a ten key "1" to "0" is used. It has been proposed that the user designates a desired telephone directory data by operating an up key or a down key from a data group having the designated first character.

[0004]

As described above, in searching for desired telephone directory data, "1" to "1" are used.
Ten keys of "0" and an up key and a down key are required, and the number of required operators is large, so that the operability is poor, and it has been difficult to reduce the size and cost of the apparatus.

Accordingly, an object of the present invention is to provide a communication terminal device in which the number of required operators is reduced to improve the operability, and the size and cost of the device are reduced. .

SUMMARY OF THE INVENTION A communication terminal device according to the present invention comprises: a data storage means in which a plurality of data groups each comprising one or a plurality of data are stored; A communication terminal device including a data search unit that performs a first operation and a second operation, and is stored in a data storage unit by operating the first operation. One data group is sequentially selected from the plurality of data groups, and the predetermined data group selected by the operation of the first operation element is determined by operating the second operation element. It is characterized in that one data is sequentially selected.

In the present invention, the data storage means includes:
A plurality of data groups each including one or a plurality of data are stored. Here, the data is character data, telephone directory data, or the like. The data search means has a first operator and a second operator. For example, the first operator is
There is a single selection key, and the second operator is an up key and a down key.

By operating the first operation element, one data group is sequentially selected from a plurality of data groups stored in the data storage means, and the selected data group is selected by a display means such as a liquid crystal display element. A display indicating the data group is displayed (for example, the display of the first character of the name). When the operation of the first operator is continuously performed, one data group is sequentially selected from the plurality of data groups at a constant time interval.

By operating the second operation element, a predetermined data group selected by operating the first operation element is determined, and thereafter, by operating the second operation element, One piece of data is sequentially selected from the predetermined data group, and the contents are displayed on the display means. When the operation of the second operator is continuously performed, one data is sequentially selected from the predetermined data group at a fixed time interval. As described above, desired data can be searched only by using the first and second operators.

After the first or last data constituting the predetermined data group is selected by the second operator, a new selection operation in a direction deviating from the predetermined data group is performed by the second operator. At this time, a transition may be made to a state in which one piece of data is sequentially selected from the data group before or after the predetermined data group by operating the second operation element. Thereby, the user does not need to select a data group before or after the predetermined data group again,
It becomes possible to select data from the data group.

After the first or last data constituting the predetermined data group is selected by the second operator, the selection operation in a direction deviating from the predetermined data group is continued by the second operator. In such a case, a transition may be made to a state in which one piece of data is sequentially selected from the end or the beginning of the predetermined data group. As a result, the user can sequentially and repeatedly select one or a plurality of data constituting a predetermined data group. In this case, the data selection time from the state where the first or last data of the predetermined data group is selected to the time when the last or first data of the predetermined data group is selected is made longer than the other data selection times. You may do so. Accordingly, the user can easily stop the operation of the second operator in a state where the first or last data of the predetermined data group is selected, and shift to the data selection state of the next data group. .

Further, when the first operator is operated in a state where predetermined telephone directory data is selected by the operation of the second operator, a call is made based on the predetermined telephone directory data. It may be. As a result, the user's calling operation can be easily performed as an extension of the telephone directory data search operation.

Further, from the state where one data is sequentially selected from a predetermined data group by operating the second operation element,
A third operator for returning to a state in which one data group is sequentially selected from a plurality of data groups by the first operator may be further provided. As a result, the selection of the data group can be restarted halfway, and the usability for the user is improved.

The data retrieval means has a first operation element and a second operation element. When the first operation element is operated, one data group is sequentially read from a plurality of data groups stored in the data storage means. A data group is selected, a predetermined data group selected by operating the first operator is determined by operating the second operator, and a second data group is determined by operating the first operator.
One data may be sequentially selected from the predetermined data group determined by the operation of the operator. In this case, when the first operation element is an up key and a down key, it is possible to select a data group and select data in both directions.

In the talking state, the TDMA processing unit 105 outputs the compressed voice data transmitted through the talking channel. The compressed audio data is supplied to the audio codec unit 106, where it is converted into an analog signal after being subjected to a decoding process. Then, the received audio signal output from the audio codec unit 106 is transmitted to the speaker 10 via the amplifier 107.
8 and the speaker 108 outputs a sound based on the received sound signal.

The transmission audio signal output from the microphone 111 is amplified by the amplifier 112, supplied to the audio codec unit 106, converted into a digital signal, and then compression-encoded to form compressed audio data. . Then, the compressed audio data output from the audio codec unit 106 is supplied to the TDMA processing unit 105, and transmitted to the other party through the communication channel.

Next, referring to FIG. 3 and FIGS. 4A and 4B,
The search operation of the telephone directory data will be described. As shown in FIG. 3, when the selection key 217 is depressed from the state before the search is started, the data group 1 is selected, and the first character “A” of the data group 1 is displayed on the display unit 116. Is displayed. Each time the selection key 217 is pressed, the next data group is selected in ascending order, and the display unit 116
Displays the first character of the selected data group. When the selection key 217 is kept depressed for a long time, the next data group is automatically selected at every predetermined time t, and when the selection key 217 is depressed and released, the next data group is selected. Is stopped. In the example of FIG.
The operation is stopped in a state where the data group whose first character is "S" is selected.

When the up key "@" or the down key "@" is depressed by the jog switch 218 while the predetermined data group is selected, the selection of the predetermined data group is determined. Then, the first data of the data group is selected, and the display unit 116
Indicates the name and telephone number of the first data. Hereafter, every time the down key is pressed,
The next data is selected in ascending order, and the display unit 116 displays the name and telephone number of the selected data. Each time the up key is pressed, the next data is selected in the descending order, which is the reverse of the down key pressing operation.

When the down key is held down for a long time, as shown in FIG. 4A, data is automatically selected in ascending order every n seconds, for example, every 200 ms, and the last data is selected. Thereafter, the state shifts to the first data selection state, and the automatic selection of data is similarly repeated. In this case, the time from the last data selected state to the first data selected state is m × n seconds (m> n).
1), which is longer than other selection intervals (n seconds). Thereby, the user can recognize that the last data is selected. If the down key is pressed and released while the last data is selected, and then the down key is pressed again, the first data of the data group one after the current data group is selected. The display unit 116 displays a name and a telephone number relating to the data.

On the other hand, when there is a long press of the up key,
As shown in FIG. 4B, data is automatically selected in descending order every n seconds, for example, every 200 ms, and after the first data is selected, the state again shifts to the last data selection state.
Similarly, the automatic selection of data is repeated. In this case, the time from when the first data is selected to when the last data is selected is m × n seconds (m> 1),
It is set to be longer than another selection interval (n seconds).
Thus, the user can recognize that the first data is selected. With the first data selected, if the up key is pressed and released, and then the up key is pressed again, the last data in the data group immediately before the current data group is selected. The display unit 116 displays a name and a telephone number relating to the data.

Next, the control operation of the control unit 101 when searching for telephone directory data will be described with reference to the flowcharts of FIGS.

First, in step ST11, the selection key 21
It is determined whether or not the data group 7 is depressed. If there is a depression, N = 1 is set in step ST12 to select the data group 1, and then the process proceeds to step ST13. In this step ST13, the first character of the data group N is displayed on the display unit 116.

Next, in step ST14, a t-second timer is started. Thereafter, in step ST15, it is determined whether or not the t-second timer has timed out.
At 6, it is determined whether or not the depression of the selection key has been stopped. If the t-second timer times out while the selection key 217 is held down for a long time, the process proceeds to step ST17. If the depression of the selection key 217 is stopped before the time-out of the t-second timer, step ST
Proceed to 18.

In step ST18, it is determined whether or not the selection key 217 has been depressed. When the selection key 217 is depressed, the process proceeds to step ST17. In step ST17, it is determined whether or not N is the maximum number of data groups Nmax. If N = Nmax, N = 1 is set in step ST19, and the process returns to step ST13. That is, the state shifts to the state where the data group 1 is selected,
The first character "A" of the data group 1 is displayed on the display unit 116, and the same control operation as described above is performed. On the other hand, N =
If it is not Nmax, N is increased by 1 in step ST20, and thereafter, the process returns to step ST13. That is,
The display unit 116 shifts to the state where the next data group N is selected.
Displays the first character of the data group N, and performs the same control operation as described above.

In step ST18, the selection key 217 is selected.
If there is no depression of the key, it is determined in step ST21 whether the up key or the down key is depressed,
Further, in step ST22, it is determined whether or not the end key 212 is depressed. End key 2 in step ST22
If there is a depression of 12, the process returns to step ST11, and the state before the start of the search is set.

When the up key or the down key is depressed in step ST21, in step ST23,
The selection of the data group N is determined, and M for specifying the data in the data group N is set to 1, so that the first data of the data group N is selected. Then, step ST2
At 4, it is determined whether or not the number NMmax of data in the data group N is one. If NMmax is not 1, step S
At T25, the display unit 116 displays the name and telephone number of the M-th data in the data group N.

Then, in a step ST31, an n-second timer is started.
It is determined whether or not the second timer has timed out, and in step ST33, it is determined whether or not the depression of the up key or the down key has been stopped. If the pressing of the up key or the down key is stopped before the n-second timer times out, it is determined in a step ST34 whether or not the pressing of the up key or the down key is performed.
When the up key or down key is pressed,
In step ST35, it is determined whether the operation is an up key operation or a down key operation.

If the operation is a down key operation, it is determined in step ST36 whether or not M = NMmax, that is, whether or not the last data of the data group N is selected. If M is not equal to NMmax, M is increased by 1 in step ST37, and thereafter, the process returns to step ST25. On the other hand, when M = NMmax, in step ST38, N
= Nmax, that is, whether or not the last data group has been selected. When N = Nmax, in step ST39, N = 1 is set, and then step S39 is performed.
When the process proceeds to T40, and N is not equal to Nmax, in step ST42, after N is increased by 1, the process proceeds to step ST4.
Proceed to 1. Then, in step ST41, M = 1 is set, and the process returns to step ST25. After returning to step ST25, the same control operation as described above is performed.

Thus, when the down key is pressed while data other than the last data in the data group N is selected, the state shifts to a state where the next data is selected in ascending order.
The display unit 116 displays the name and telephone number of the data. When the down key is pressed while the last data of the data group N is selected, the next data group is selected in ascending order, and the first data is shifted to the selected state. The name and telephone number of the data are displayed. In this case, when the last data group is selected, the state shifts to the first data group selected state.

If the up key is operated in step ST35, it is determined in step ST43 whether or not M = 1, that is, whether or not the first data of the data group N is selected. . If M is not 1, M is decreased by 1 in step ST44, and thereafter, in step ST44.
Return to 25. On the other hand, when M = 1, step ST
At 45, it is determined whether or not N = 1, that is, whether or not the first data group is selected. If N = 1, the process proceeds to step ST47 after setting N = Nmax in step ST46. On the other hand, if N = 1, N is reduced by 1 in step ST48, and then the process proceeds to step ST47.
Go to 47. Then, in step ST47, M = NMmax
And returns to step ST25. Step ST2
After returning to 5, the same control operation as described above is performed.

When the up key is depressed in a state in which data other than the first data in the data group N is selected, the state shifts to a state in which the next data is selected in descending order.
The display unit 116 displays the name and telephone number of the data. If the up key is pressed while the first data in the data group N is selected, the next data group is selected in descending order, and the state is shifted to the state in which the last data is selected. The name and telephone number of the data are displayed. In this case, when the first data group has been selected, the state shifts to the last data group selected state.

If there is no depression of the up key and the down key in step ST34, step ST5 is executed.
In step ST52, it is determined whether or not the hold key 213 has been depressed. In step ST52, it is determined whether or not the selection key 217 has been depressed. In step ST53, whether or not the end key 212 has been depressed. Is determined. When the hold key 213 is depressed, the process returns to step ST13, and shifts to a state where the first character of the data group N is displayed on the display unit 116 with the data group N selected.
That is, the state returns to a state where the data group can be selected in ascending order from the data group N by the selection key 217.

If the selection key 217 is depressed in step ST52, the process proceeds to step ST50 to shift to a calling process using the selected data. By adopting a configuration in which the operation shifts to the calling process by operating the selection key 217 in this manner, the user can easily perform the calling operation as an extension of the operation of searching the telephone directory data. Instead of pressing the selection key 217 as described above, the calling process may be shifted to the calling process by pressing the talk key 211 as conventionally known. Step ST
If the end key 212 is depressed at 53, the process returns to step ST11 to set the state before the start of the search.

If it is determined in step ST32 that the n-second timer has timed out while the up key or the down key is being pressed for a long time, then in step ST54, the operation state of the up key or the down key is changed. It is determined whether there is. If the down key has been operated, it is determined in step ST55 whether or not M = NMmax, that is, whether or not the last data of the data group N has been selected.

If M = NMmax, step ST5
In M6, M = 1, the first data of the data group N is selected, and the process returns to step ST25. On the other hand, M = NM
If it is not max, M is increased by 1 in step ST57, and the next data is selected in ascending order, and then the process proceeds to step ST58. In step ST58, M =
It is determined whether or not NMmax, that is, whether or not the selected data is the last data of the data group N. M = NMmax
If not, the process returns to step ST25, while M = NMma
If it is x, the process proceeds to step ST71.

Thus, when the down key is pressed and held, the data of the data group N is automatically selected in ascending order. Then, after the last data is selected, the state shifts to the first data selection state. In this case, the data selection time from when the last data is selected to when the first data is selected is m × n seconds (m> 1) in a control operation after step ST71 described later, and in other states. It is longer than the data selection time (n seconds). The user
It is easy to recognize that the last data of the data group N is being selected, and it is easy to stop pressing down key and shift to the state of selecting data from the next data group. (Refer to ST34 and ST35 and thereafter).

If it is determined in step ST54 that the up key has been operated, it is determined in step ST59 whether M = 1, that is, whether the first data of the data group N has been selected. judge.

If M = 1, step ST60
Then, M = NMmax, the last data of the data group N is selected, and the process returns to step ST25. On the other hand, M =
If it is not 1, M is decreased by 1 in step ST61, the next data is selected in descending order, and the process proceeds to step ST62. In step ST62, M = 1
, That is, whether the selected data is the first data in the data group N. If M = 1, the process returns to step ST25, while if M = 1, the process proceeds to step ST71.

Thus, when the up key is pressed and held, the data of the data group N is automatically selected in descending order. Then, after selecting the first data, the state shifts to a state of selecting the last data. In this case, the data selection time from when the first data is selected to when the last data is selected is m × n seconds (m> 1) in a control operation after step ST71 described later, and in other states. It is longer than the data selection time (n seconds). The user
It is easy to recognize that the first data of the data group N is being selected, and it is easy to stop pressing down the up key and shift to the selection state of data from the immediately preceding data group. (Refer to ST34 and ST35 and thereafter).

Next, steps after step ST71 (FIG. 7) will be described. When NMmax = 1 in step ST24 described above, the process proceeds to step ST71. In step ST71, the display unit 116 displays the name and telephone number of the M-th data in the data group N. And step S
At T72, the m × n-second timer is started, and thereafter, at step ST73, it is determined whether or not the m × n-second timer has timed out. At step ST74, whether the pressing of the up key or the down key has been stopped is determined. Is determined. If the depression of the up key or the down key is stopped before the m × n second timer times out, the process returns to step ST34 to perform the same control operation as described above.

On the other hand, if the depression of the up key or the down key continues and the m × n seconds timer times out, the process proceeds to step ST80. This step ST80
Then, it is determined whether or not NMmx is 1, that is, whether or not the data in the data group N is one. If NMmax = 1, the process returns to step ST71. Thus, when the number of data in the data group N is one, while the depression of the up key or the down key is continued, the selection state of the one data continues, the depression is stopped, and the depression is performed again. Is performed, the state shifts to a state of selecting data of the preceding and succeeding data groups. On the other hand, if NMmx is not 1, the process returns to step ST54 and performs the same control operation as described above.

As described above, in this embodiment, only the selection key 217 and the up key and the down key (the jog switch 218) are used, and a plurality of telephone directories stored in the nonvolatile memory 117 are stored.

After the first or last data constituting the predetermined data group is selected by depressing the up key or the down key, the data is deviated from the predetermined data group by newly depressing the up key or the down key. Is performed, the state shifts to a state where one data is sequentially selected from the data group before or after the predetermined data group by depressing the up key or the down key. Therefore, the user can select data from the predetermined data group without selecting the data group before or after the data group again, and the usability of the user is improved.

After the first or last data constituting the predetermined data group is selected by depressing the up key or the down key, selection in a direction deviating from the predetermined data group is performed by depressing the up key or the down key. When the operation is continued, the state shifts to a state where one piece of data is sequentially selected from the last or first data of the predetermined data group. Therefore, one or a plurality of data constituting a predetermined data group is sequentially and repeatedly selected, and the user's selection operation is facilitated.

In this case, the data selection time (m × n seconds) from the state where the first or last data of the predetermined data group is selected to the time when the last or first data of the predetermined data group is selected. Is longer than the data selection time (n seconds) in other states. Therefore,
The user can easily know that the first or last data of the predetermined data group is in the selected state, stop pressing the up key or the down key, and change to the data selection state of the next data group. It is easy to make the transition.

When the selection key 217 is depressed in a state where predetermined telephone directory data is selected by depressing the up key or the down key, a call is made based on the predetermined telephone directory data. Therefore, the user can easily perform the calling operation as an extension of the operation of searching the telephone directory data.

When one data is sequentially selected from a predetermined data group by depressing the up key or the down key, when the hold key 213 is depressed, a plurality of data groups are depressed by depressing the selection key 217. The state returns to the state of sequentially selecting one data group. Therefore, the selection of the data group can be restarted halfway, and the usability for the user is improved.

In the above embodiment, the data group is selected by pressing down the selection key 217, the selection of that data group is confirmed by pressing down the up key or down key, and then the up key or down key is pressed down.
