Abstract

PROBLEM TO BE SOLVED: To make the size of the title device small, to reduce the weight and to decrease the cost. SOLUTION: In a lateral movement mode, a cursor is moved in lateral directions (left or right direction) through a long-depression operation of an UP key and a DOWN key. When the cursor is moved to an end of a screen, the cursor cannot be moved and the lateral movement mode is changed into a longitudinal movement mode (ST1-ST5). In the longitudinal movement mode, the cursor is moved in longitudinal directions (upward or downward) through the operation of the UP key and the DOWN key (ST8, ST9). In this case, scrolling the image on the screen moves the cursor. When no key operation is made for a prescribed time in this longitudinal movement mode, the lateral movement mode is again obtained (ST7, ST8, ST1). The movement mode is properly changed depending on the position of the cursor and a key non- operation period and only the two keys can move the cursor on the screen two-dimensionally. Thus, the number of keys provided to the device main body can be reduced, and the device is made small in size, made light in weight and the cost can be reduced.

In this case, when the user rotates the operation member clockwise, the up key is pressed down, and when the user rotates the operation member counterclockwise, the down key is pressed down. . The operating member that has been rotated is automatically returned to the neutral position.

Next, the simplified portable telephone 100 shown in FIG.
Will be described. When the power is turned on, the control channel is out of synchronization with the control channel. Therefore, the control channel transmitted from the base station is received and the synchronization with the control channel is established. In this case, a search operation of sequentially receiving control channels of available public base stations is performed, and a maximum control channel whose received signal strength (RSSI: Receive Signal Strength Indicate) is equal to or higher than a selection level and is selected,
Synchronization with the control channel is established. After that, location registration is performed to be in the area of the base station associated with the control channel for which synchronization has been established. This location registration is performed using a call channel. After the location registration is completed, the mobile station returns to the reception state of the control channel for which synchronization has been established, and enters a standby state.

The operation for making a call will be described.
In this case, for example, if the call key 211 is operated by inputting the telephone number of the other party by key operation of the operation unit 115, or the call key 211 is operated after searching the telephone directory data, a calling process is performed. That is, the control unit 101 transmits telephone number data and the like as control data to the TDMA processing unit 1.
05 and transmitted to the base station on the control channel.
As a result, the line connection with the other party is established, and a call state is established.

Here, the communication is performed using the communication channel. At the time of the line connection processing, the communication frequency and the slot position data of the communication channel are transmitted as control data from the base station using the control channel. TDMA
It is supplied from the processing unit 105 to the control unit 101. Control unit 1
01 controls the radio section 103 based on the communication frequency data so that the transmission / reception frequency matches the communication frequency of the communication channel, and sets the slot selected by the TDMA processing section 105 based on the slot position data. . As a result, a call can be made using the call channel notified from the base station.

Paging data is transmitted from the base station as control data using the control channel. The paging data is supplied from the TDMA processing unit 105 to the control unit 101, and when the incoming call is detected, the control unit 101 Buzzer 1
18 is sounded, and the incoming call lamp 119 is controlled to light up, and the user is notified of the incoming call.

In this state, the call key 211 is
Is operated and a response data is supplied from the control unit 101 as control data to the TDMA processing unit 105, and is transmitted to the base station via the communication channel. As a result, the line connection with the other party is established, and a call state is established.

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 section 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, the case where the function key 217 is set to the character input mode will be described. In this case, the display unit 116
Displays a character input screen on which characters (sentences) are input and edited. A cursor is displayed on this character input screen, and the user can move the cursor position to specify a character input position and an edit position. In the present embodiment, the user can perform the operation of moving the cursor position using only the jog switch 218, that is, only the up key and the down key. However, at this time, the character display direction of the display unit 116 is
Since the left side of 0 is displayed as a downward direction, the jog switch 218 functions as a lateral movement key at the start of operation.

FIG. 3 is a flowchart showing a cursor moving process of the control unit 101 in the character input mode. First, in step ST1, a horizontal movement mode for moving the cursor in the left and right directions is set. Then, in step ST2, it is determined whether there is a long press of the up key or the down key. In this case, when the pressing operation of the up key or the down key has been continued for a predetermined time, for example, 1 second or more, it is determined that there is a long press. If there is a long press, the process proceeds to step ST3.

In step ST3, it is determined whether the cursor can be moved in the horizontal direction specified by the key. Here, the horizontal direction specified by the key is the left direction when the up key is long-pressed, and the right direction when the down key is long-pressed. In this case, when the cursor moves in the horizontal direction specified by the key in the horizontal movement mode and reaches the end of the character input screen, it is determined that the movement is impossible.

If it is determined that the cursor can be moved, the process proceeds to step ST4 to move the cursor in the horizontal direction specified by the key, and thereafter returns to step ST2.
Thus, when the pressing of the up key or the down key is continued, the cursor sequentially moves leftward or rightward. As described above, in the horizontal movement mode, the cursor moves in the horizontal direction only when the up key or the down key is pressed for a long time, and the cursor moves in the horizontal direction due to an erroneous operation of the up key or the down key. Can be prevented from moving. Of course, before determining the long press of the up key or the down key, the movement in the pressed direction may be performed by one cursor. At this time, cursor movement control can be quickly performed for key input.

On the other hand, if it is determined in step ST3 that the cursor cannot be moved, the process proceeds to step ST5.
In this step ST5, the mode is changed from the horizontal movement mode described above to the vertical movement mode in which the cursor is moved in the vertical direction. Then, in step ST6, the timer is started.
It is determined whether 0 ms has elapsed. 200ms
If not, the process proceeds to step ST8.

In step ST8, it is determined whether or not the up key or the down key has been pressed. If the up key or the down key has been depressed, the process proceeds to step ST9 to move the cursor in the vertical direction specified by the key, and thereafter returns to step ST6. Here, the vertical direction specified by the key is upward when the up key is depressed, and is downward when the down key is depressed.

As described above, by returning to step ST6 after the processing in step ST9, the cursor is sequentially moved upward or downward by pressing the up key or the down key without stopping for 200 ms or more. I will do it. In step ST9, the cursor is moved vertically with respect to the character input screen.
In the present embodiment, this is realized by scrolling the character input screen in the vertical direction. Thus, even when the cursor is moved in the vertical direction with respect to the character input screen, the cursor remains displayed at a predetermined position on the display unit 116.

If there is no depression of the up key or the down key in step ST8, the process returns to step ST7. When 200 ms has elapsed in step ST7, the process returns to step ST1 to change the mode from the vertical movement mode to the horizontal movement mode. Therefore, when there is no operation of the up key or the down key for 200 ms or more in the vertical movement mode, the vertical movement mode is automatically changed to the horizontal movement mode.

Next, an example of the operation of moving the cursor CS will be described with reference to FIGS. Initially, it is assumed that the cursor CS is displayed in the position shown in FIG. 4A with respect to the character input screen PCI in the horizontal movement mode. When the up key is pressed for a long time in this state, FIG.
As shown in (b), the cursor CS moves to the left. And if the long press of the up key is continued,
As shown in FIG. 4C, the cursor CS moves to the left end of the character display screen PCI, and is changed from the horizontal movement mode to the vertical movement mode. Then, when the pressing of the up key is further continued, FIGS. 4 (d), (e), and (f)
As shown in (1), the cursor CS sequentially moves upward with respect to the character display screen PCI by scrolling the character display screen PCI downward.

For example, when the cursor CS is moved to the position shown in FIG.
When the down key is depressed within 200 ms after moving to the position shown in FIG. 4A, the character display screen PC is displayed as shown in FIG.
By the upward scroll of I, the cursor CS moves downward with respect to the character display screen PCI. Then, when the depression of the down key is continued, as shown in FIG.
As shown in (i), when the character display screen PCI is scrolled upward, the cursor CS is moved to the character display screen PCI.
Sequentially move downward.

For example, when the cursor CS is moved to the state shown in FIG.
After moving to the position shown in FIG. 5 (f), pressing down of the up key is stopped, and when 200 ms has elapsed, the mode is changed from the vertical movement mode to the horizontal movement mode. When the up key is pressed for a long time after the mode is changed to the horizontal movement mode, the cursor CS moves to the right end of the previous line, as shown in FIG. Then, when the long press of the up key is continued, FIG.
As shown in (k) and (l), the cursor CS sequentially moves to the left.

When the down key is pressed for a long time after the mode has been changed to the lateral movement mode as described above, FIG.
As shown in (m), the cursor CS moves rightward. And if the down key is kept pressed,
As shown in FIGS. 5 (n) and 5 (o), the cursor CS sequentially moves to the right.

In the above-described moving operation example, the case where the up key is long-pressed first and the cursor CS moves leftward has been described. A brief description will be given.

In the state of FIG. 4A, when the down key is pressed for a long time, the cursor CS sequentially moves to the right, and when it moves to the right end of the character display screen PCI, the cursor moves from the horizontal movement mode to the vertical movement mode. Is changed to When the up key or the down key is depressed after the change to the vertical movement mode, the scroll of the character display screen PCI causes the cursor CS to move upward or downward with respect to the character display screen PCI. Move sequentially. Also,
When 200 ms elapses without pressing down the up key or the down key in the vertical movement mode, the mode is changed from the vertical movement mode to the horizontal movement mode again. And
After the mode is changed to the horizontal movement mode, when the up key is pressed for a long time, the cursor CS sequentially moves to the left. When the down key is pressed for a long time, the cursor CS moves to the left end of the next line. It moves and moves to the right sequentially.

As described above, in the present embodiment, the cursor displayed on the character input screen of the display unit 116 in the character input mode is moved by the jog switch 21.
8, therefore, the character input screen can be arbitrarily moved in the left-right direction and the up-down direction using the two keys of the up key and the down key. Therefore, according to the present embodiment,
The number of keys provided on the telephone body can be reduced as compared with the conventional case, and the size, weight, and cost can be reduced.

In the above-described embodiment, in the horizontal movement mode, when the up key or the down key is pressed for a long time, the cursor moves in the horizontal direction specified by the operated key. When the cursor is located at the end in the direction specified by the operated key from the beginning, the line on which the cursor is positioned is changed, and the cursor moves in the horizontal direction specified by the operated key ( (See FIG. 3).

However, in the lateral movement mode, when the up key or the down key is depressed, immediately
The cursor may be moved in the horizontal direction specified by the operated key, and if the cursor is located at the end in the direction specified by the operated key from the beginning, a condition that the key is held down is required. The mode may be changed to the vertical movement mode, and the cursor may be moved in the vertical direction specified by the operated key.

FIG. 6 is a flowchart showing a cursor moving process of the control unit 101 in the character input mode for realizing the above. In FIG. 6, steps corresponding to those in FIG. 3 are denoted by the same reference numerals.

First, in step ST1, a horizontal movement mode for moving the cursor in the left and right directions is set. Then, in a step ST11, it is determined whether or not the up key or the down key is depressed. If the up key or the down key is depressed, step ST12
Proceed to.

In step ST12, it is determined whether the cursor can be moved in the horizontal direction specified by the key. Here, the horizontal direction specified by the key is the left direction when the up key is pressed down, and the right direction when the down key is pressed down. When the cursor is located at the lateral end, it is determined that movement is impossible. Note that the cursor is located at the end portion when the cursor is at the end portion from the beginning of the key operation, or when the cursor moves by the key operation and reaches the end portion.

If it is determined that the cursor can be moved, in step ST13, the cursor is moved in the horizontal direction specified by the key, and thereafter, the process proceeds to step ST14.
On the other hand, when it is determined that the cursor cannot be moved, the process immediately proceeds to step ST14. Step ST1
At 4, it is determined whether or not the long press of the up key or the down key is determined. In this case, when the pressing operation of the up key or the down key has been continued for a predetermined time, for example, 1 second or more, it is determined that the long press is determined.

If the long press of the key is not determined, the process returns to step ST11. On the other hand, when the long press of the key is determined, the process proceeds to step ST15. This step ST1
At 5, it is determined whether the cursor can be moved in the horizontal direction specified by the key. This determination is also performed in the same manner as the determination in step ST12 described above. If it is determined that the cursor can be moved, the process proceeds to step ST
The program proceeds to step 4, where the cursor is moved in the horizontal direction specified by the key, and thereafter, the process returns to step ST11. As a result, when there is no cursor at the horizontal end specified by the operated key, the cursor sequentially moves leftward or rightward with the key operation.

If it is determined in step ST15 that the cursor cannot be moved, the process proceeds to step ST5. In this step ST5, the mode is changed from the horizontal movement mode described above to the vertical movement mode in which the cursor is moved in the vertical direction. Then, in step ST6, the timer is started, and thereafter, in step ST7, it is determined whether or not the timer indicates that 200 ms has elapsed. 200
If ms has not elapsed, the process proceeds to step ST8.

In step ST8, it is determined whether or not the up key or the down key has been pressed. If the up key or the down key has been depressed, the process proceeds to step ST9 to move the cursor in the vertical direction specified by the key, and thereafter returns to step ST6. Here, the vertical direction specified by the key is upward when the up key is depressed, and is downward when the down key is depressed.

As described above, by returning to step ST6 after the processing of step ST9, the cursor is sequentially moved upward or downward by depressing the up key or the down key without stopping for 200 ms or more. I will do it. The vertical movement of the cursor is realized, for example, by scrolling the character input screen in the vertical direction. As a result, even if the cursor is moved in the vertical direction with respect to the character input screen, the cursor remains at a predetermined position on the display unit 116.

If there is no depression of the up key or the down key in step ST8, the process returns to step ST7. When 200 ms has elapsed in step ST7, the process returns to step ST1 to change the mode from the vertical movement mode to the horizontal movement mode. Therefore, when there is no operation of the up key or the down key for 200 ms or more in the vertical movement mode, the vertical movement mode is automatically changed to the horizontal movement mode.

According to the cursor movement processing shown in the flowchart of FIG. 6, in the horizontal movement mode, when the up key or the down key is depressed, the cursor is immediately moved in the horizontal direction designated by the operated key. Is moved, and if it is located at the end in the direction specified by the operated key from the beginning, the mode is changed to the vertical movement mode on condition that the key is long-pressed, and the vertical movement mode specified by the operated key is The cursor moves in the direction.

Next, an example of the operation of moving the cursor CS will be described with reference to FIGS. Initially, it is assumed that the cursor is in the horizontal movement mode and the cursor CS is displayed at a position as shown in FIG. 7A with respect to the character input screen PCI. When the up key is pressed in this state, the cursor CS moves to the left as shown in FIG. 7B. Then, when the pressing of the up key is continued, the cursor CS moves to the left end of the character display screen PCI as shown in FIG. In this state, if the press of the up key continues for more than a predetermined time and a long press is confirmed,
The mode is changed from the horizontal movement mode to the vertical movement mode.
And if the up key continues to be depressed,
As shown in FIG. 7D, the cursor CS is moved downward by the scrolling of the character display screen PCI.
It moves upward with respect to CI.

It is also assumed that the cursor is initially in the horizontal movement mode, and the cursor CS is located at the left end as shown in FIG. In this state, the up key is depressed, and when the long press is confirmed, the mode is changed from the horizontal movement mode to the vertical movement mode. And FIG.
As shown in (b), by scrolling the character display screen PCI downward, the cursor CS is moved to the character display screen PCI.
It moves upward with respect to. On the other hand, if the down key is pressed in the state of FIG. 8A, the cursor CS moves rightward as shown in FIG. 8C.

In the above embodiment, the first movement mode is the horizontal movement mode and the second movement mode is the vertical movement mode. However, the first movement mode is the vertical movement mode. A movement mode in which the second movement mode is the lateral movement mode is also conceivable.

Further, in the above-described embodiment, the present invention is applied to a simple type portable telephone. However, the present invention has a display unit so that a cursor is displayed on a screen of the display unit. It goes without saying that the present invention can be similarly applied to other communication terminal devices.

[0068]

According to the present invention, the movement mode is appropriately changed based on the cursor position and the key non-operation period, and the cursor on the screen can be moved two-dimensionally with only two keys. Therefore, the number of keys disposed on the apparatus main body can be reduced as compared with the conventional case, and the apparatus can be reduced in size, weight, and cost.
