The CPU 20 controls the display control section 24 mainly in accordance with the display control program, and displays various display screens on the display section 7.

(3) Display of Items on Mobile Phone In the mobile phone 1, on a screen having a plurality of selectable items, such as a telephone directory screen and a schedule screen, the plurality of items are displayed in a list on the display unit 7. The user can select and determine any item by rotating and pressing the jog dial 9.

For example, when the power of the portable telephone 1 is turned on by pressing the power / end key 10, the CPU 20 first displays a standby screen (not shown) on the display unit 7, and in this state, the jog dial 9 is turned on. When pressed, the CPU 20 displays a main menu screen (not shown) on the display unit 7 accordingly.

Then, for example, when "Phonebook" is selected on the main menu screen, the CPU 20 displays a telephone book screen 100 shown in FIG.

In the telephone directory screen 100, a plurality of icons indicating various information such as a radio wave reception state, an e-mail, and a remaining battery level are displayed at the upper end of the screen. An item display area 101 for displaying a list of destination names as items in a list is displayed.

The CPU 20 follows the display control program,
As the initial state, the seven destination names stored in the telephone directory list in the RAM 22 are read from the top seven items, and the read destination names are displayed as a list in the item display area 101 as items 102A to 102G, and a rectangular cursor is displayed. 103 is displayed with the item 102A displayed at the top of the item display area 101 selected. CPU2
0 indicates a downward icon 10 of a downward triangle for notifying the user that there is an item hidden below the item display area 101 on the lower right side of the item display area 101.
4 is displayed.

In this state, the jog dial 9 is operated by one click rotation downward, and the jog dial 9 is
When the rotation pulse is supplied to the CPU 20, the CPU 20 moves the cursor 103 downward by one item in response to the rotation pulse, and displays the next item 102B in a selected state. When the jog dial 9 is clicked upward one rotation, CP
U20 moves cursor 103 upward by one item in response to this and displays it.

Thus, in the mobile phone 1, the cursor 1 is turned by rotating the jog dial 9 up and down.
03 is moved so that the item displayed in the item display area 101 can be arbitrarily selected.

Then, the cursor 103 is moved to the item display area 1
When the jog dial 9 is further rotated by one click while the item 102G displayed at the bottom of 01 is selected, the CPU 20 correspondingly deletes the item 102A displayed at the top. Item 1 with
02B to 102G are moved upward by one step and displayed.

Further, the CPU 20 reads out the destination name next to the destination name displayed in the item 102G from the telephone directory data in the RAM 22, and uses this as the item 102F (not shown) as the bottom row of the item display area 101. Is displayed newly. At this time, the CPU 20 does not move the cursor 103, whereby the cursor 103 is displayed with the newly displayed item 102F selected.

The CPU 20 also provides a downward icon (not shown) consisting of an upward triangle to notify the user that an item hidden above the item display area 101 exists.
Is displayed on the right side of the upper end of the item display area 101.

Thus, in the cellular phone 1, when the jog dial 9 is further rotated downward while the cursor 103 selects the lowermost item in the item display area 101, the entire item is moved without moving the cursor 103. Scroll display to move up.

Similarly, in the mobile phone 1, when the jog dial 9 is further rotated upward while the cursor 103 selects the uppermost item in the item display area 101, the entire item is moved without moving the cursor 103. Scroll down.

As described above, in the portable telephone 1, every time the jog dial 9 is rotated, one item is read from the RAM 22 and displayed by scrolling, so that the item selected by the cursor 103 is switched and displayed. This display mode is called a normal scroll mode.

In the normal scroll mode, when the jog dial 9 is continuously rotated in the same direction within a predetermined reference time (for example, 0.5 seconds), the mobile phone 1 is turned into the automatic scroll mode as shown in FIG. Move to

In the automatic scroll mode, the mobile phone 1 continuously reads items from the RAM 22 at predetermined read timings and automatically scrolls and displays the items at a predetermined reference speed, so that the item selected by the cursor 103 is automatically displayed. Switch to and display. Thus, the user can easily and quickly search and select a desired item without operating the jog dial 9.

Further, in the automatic scroll mode, when the continuous rotation operation of the jog dial 9 is repeated a predetermined number of times or more, the mobile phone 1 shifts to the high-speed automatic scroll mode.

In the high-speed automatic scroll mode, the mobile phone 1 automatically performs scroll display at a speed corresponding to the number of repetitions of the continuous rotation operation, so that the cursor 10
The item selected by 3 is switched at a high speed and displayed. Thus, the user can control the scroll display speed of the mobile phone 1 only by continuously rotating the jog dial 9, and can search and select a desired item at a higher speed.

(3-1) Scroll Display Processing Next, a processing procedure for performing the above-described scroll display will be described in detail with reference to flowcharts shown in FIGS. 6, 7, and 8.

When, for example, "Phonebook" is selected on the main menu screen, the CPU 20 as a switching means responds to this from the start step of the normal scroll mode processing procedure of the routine RT1 shown in FIG.
Move on to

At step SP1, the CPU 40 displays the telephone directory screen 100 (FIG. 4) on the display unit 7, and proceeds to the next step SP2.

In step SP2, the CPU 20 determines whether the cancel key 13 has been pressed. If a positive result is obtained in step SP2, this indicates that the cancel key 13 has been pressed and the telephone directory screen has been canceled, and the CPU 40 proceeds to step S2.
Moving to P9, the count value Count of the jog counter for counting the number of continuous rotation operations of the jog dial 9 is set to "0", and the process proceeds to the next step SP10, where the standby screen is displayed on the display unit 7, and in step SP11. The process ends.

On the other hand, if a negative result is obtained in step SP2, this means that the cancel key 13 has not been pressed and the telephone directory screen has not been canceled, and the CPU 20 proceeds to step SP3.

In step SP3, the CPU 20 determines whether or not the jog dial 9 has been pressed.

If a positive result is obtained in step SP3, this means that the jog dial 9 is pressed down,
The cursor 103 indicates that the item being selected has been selected, and the CPU 20 proceeds to step SP12, sets the count value Count of the jog counter to “0”, stores it in the RAM 22, and proceeds to the next step SP13. .

In step SP13, the CPU 20
The destination telephone number corresponding to the selected item (that is, the destination name) is read from the RAM 22, displayed on the display unit 7 as a detailed screen (not shown) together with the destination name, and the process ends in step SP14.

On the other hand, if a negative result is obtained in step SP3, this means that the jog dial 14 has not been pressed and the item being selected has not been selected, and the CPU 20 proceeds to step SP4. .

In step SP4, the CPU 20 determines whether or not the jog dial 9 has been rotated. If a negative result is obtained in step SP4, this means that the jog dial 9 has not been rotated, and the CPU 20 returns to step SP2.

On the other hand, if a positive result is obtained in step SP4, this indicates that the jog dial 9 has been rotated, and the CPU 20 proceeds to step SP5.

In step SP5, the CPU 20 determines whether or not a timer A (not shown) for measuring a reference time (for example, 0.5 seconds) for a continuous rotation operation on the jog dial 9 is being activated. If a negative result is obtained in step SP4, this means that the timer A is not running, that is, whether the jog dial 9 is first rotated in the normal scroll mode or 0.5 seconds of the reference time since the previous rotation operation. Has elapsed and the timer A has stopped (the jog dial 9 has not been continuously rotated), and the CPU 20 proceeds to step SP6.

In step SP6, the CPU 20 sets the count value Count of the jog counter to "1", starts the timer A in step SP7, and executes the next step SP
Move to 8. In step SP8, the CPU 20 reads items corresponding to the rotation operation of the jog dial 9 from the RAM 22 and scrolls and displays one item in the rotation operation direction.
It returns to step SP2.

On the other hand, if an affirmative result is obtained in step SP4, this means that the timer A is running, that is, the jog dial 9 has been continuously rotated, and the CPU 20 proceeds to step SP15. Move on.

In step SP15, the CPU 20
It is determined whether the jog dial 9 has been rotated in the same direction as the previous time. If a negative result is obtained in step SP15, this indicates that the jog dial 9 has been rotated in the opposite direction to the previous operation, and the CPU 20 proceeds to step SP6 and counts the count value Coun of the jog counter.
After setting t to "1", the timer A is restarted in step SP7, and one item is scroll-displayed in the rotation operation direction of the jog dial 9 in step SP8.

On the other hand, if a positive result is obtained in step SP15, this means that the jog dial 9 has been rotated in the same direction within the reference time, that is, that the jog dial 9 has been continuously rotated. Moves to step SP6, and counts the count value of the jog counter.
Is set to "2", the routine proceeds to the automatic scroll mode processing procedure of the routine RT2.

As described above, in the normal scroll mode, the CPU 20 serving as the switching means operates the jog dial 9.
Is rotated at an interval longer than the reference time of the timer A, the scroll display is performed one item at a time in the direction corresponding to the rotation operation, and the jog dial 9 is continuously rotated twice within the reference time of the timer A. When the rotation operation is performed in the direction (continuous rotation operation), the mode shifts to the automatic scroll mode.

Next, the automatic scroll mode processing procedure will be described in detail with reference to FIG. In FIG. 7, the CPU 20 as the automatic switching means enters from the start step of the automatic scroll mode processing procedure of the routine RT2 and moves to step SP21.

At step SP21, the CPU 40
It is determined whether the cancel key 13 has been pressed. If a positive result is obtained in step SP21, this indicates that the cancel key 13 has been pressed and the telephone directory screen has been canceled.
Step 20 goes to step SP28, where the count value Count of the jog counter is set to "0" and the next step SP2
9, the standby screen is displayed on the display unit 7, and step SP
The process ends at 30.

On the other hand, if a negative result is obtained in step SP21, this means that the cancel key 13
Indicates that the button has not been pressed and the telephone directory screen has not been cancelled, and the CPU 20 proceeds to step SP22.

At step SP22, the CPU 20
It is determined whether or not the jog dial 9 has been pressed.

If an affirmative result is obtained in step SP22, this means that the jog dial 9 has been pressed and the item being selected has been selected.
The CPU 20 proceeds to step SP31, sets the count value Count of the jog counter to “0”, proceeds to the next step SP32, reads the destination telephone number corresponding to the selected item (destination name) from the RAM 22, A detailed screen is displayed on the display unit 7 together with the destination name, and the process ends in step SP33.

On the other hand, if a negative result is obtained in step SP22, this means that the jog dial 9 has not been pressed and the item being selected has not been selected, and the CPU 20 proceeds to step SP23. Move on.

In step SP23, the CPU 20
It is determined whether or not the jog dial 9 has been rotated.
If a positive result is obtained in step SP23, this indicates that the jog dial 9 has been rotated, and the CPU 20 proceeds to step SP24.

At step SP24, the CPU 20
It is determined whether the jog dial 9 has been rotated in the same direction as the previous time. If a negative result is obtained in step SP24, this means that the jog dial 9 has been rotated in the direction opposite to the previous operation, and the CPU 20 proceeds to step SP38 and moves to the count value Co of the jog counter.
After setting unt to "1", the automatic scroll mode is ended and the routine returns to the normal scroll mode processing procedure of the routine RT1.

Thus, in the mobile phone 1, by rotating the jog dial 9 in the reverse direction in the automatic scroll mode, the automatic scroll mode is released and the normal scroll mode can be restored.

On the other hand, if a positive result is obtained in step SP24, this means that the jog dial 9 has been rotated in the same direction as the previous time, that is, the jog dial 9 has been continuously rotated in the automatic scroll mode. Then, the CPU 20 proceeds to step SP25 and adds "1" to the count value Count of the jog counter, and then proceeds to step SP26.

At step SP26, the CPU 20
The timer B (not shown) for measuring the reference time of the continuous rotation operation of the jog dial 9 in the automatic scroll mode is started, and the routine goes to the next step SP27.

At the step SP27, the CPU 20
It is determined whether or not the count value Count of the jog counter is “5” or more. If a negative result is obtained in step SP24, this means that the count value Count is "5".
And the CPU 20 determines in step S
The process proceeds to P28, and the RAM2 is read at every predetermined read timing.
The items are continuously read out from No. 2 and automatically scroll-displayed at a predetermined reference speed, and the process returns to step SP21.

On the other hand, if a positive result is obtained in step SP27, this means that the count value Count is equal to or more than "5", that is, the continuous rotation operation has been repeated a predetermined number of times (in this case, three times). And C
The PU 20 shifts to the high-speed automatic scroll mode processing procedure of the routine RT3.

On the other hand, if a negative result is obtained in step SP23, this indicates that the jog dial 9 has not been rotated, and the CPU 20 proceeds to step SP34.

At step SP34, the CPU 20
It is determined whether or not the timer B is running. Step S
If an affirmative result is obtained in P34, this means that the timer B is being started, that is, the reference time has not elapsed since the last rotation operation in the automatic scroll mode, and the CPU 20 determines in step SP
28, the automatic scroll display is performed.

On the other hand, if a negative result is obtained in step SP34, this means that the timer B is not running, that is, whether the rotation operation has not yet been performed in the automatic scroll mode or the reference has been determined since the previous rotation operation was performed. This indicates that the time has elapsed, and the CPU 20 proceeds to step SP35.

At step SP35, the CPU 20
The count value Count of the jog counter is decremented by "1", the timer B is started in step SP36, and the next step SP
Move to 37.

At the step SP37, the CPU 20
It is determined whether or not the count value Count of the jog counter is “2” or more. If a positive result is obtained in step SP37, this means that the count value Count of the jog counter is "2" or more, and the CPU
In step SP28, automatic scroll display is performed.

On the other hand, if a negative result is obtained in step SP37, this means that the count value Count of the jog counter is less than “2”,
The CPU 40 ends the automatic scroll mode and returns to the normal scroll mode processing procedure of the routine RT1.

As described above, in the automatic scroll mode, the CPU 20 as the automatic switching means sets the count value Count of the jog counter to "1" when the jog dial 9 is rotated in the same direction within the reference time of the timer B.
When the jog dial 9 is not rotated within the reference time of the timer B, the count value Count of the jog counter is decremented by "1".

The CPU 20 determines that the jog dial 9 is continuously rotated and the count value of the jog counter is counted.
When the value becomes “5” or more, the mode shifts to the high-speed automatic scroll mode, while the count value of the jog counter Coun
When the value of t falls below “2” and when the jog dial 9 is rotated in the reverse direction, the mode returns to the normal scroll mode.

Next, the high-speed automatic scroll mode processing procedure will be described in detail with reference to FIG. In FIG. 8, the CPU 20 as the high-speed switching means enters from the start step of the high-speed automatic scroll mode processing procedure of the routine RT3 and proceeds to step SP41.

At step SP41, the CPU 20
It is determined whether the cancel key 13 has been pressed. If a positive result is obtained in step SP41, this indicates that the cancel key 13 has been pressed and the telephone directory screen has been cancelled.
Step 20 goes to step SP49 and sets the count value Count of the jog counter to "0", and then proceeds to step SP5.
0, the standby screen is displayed on the display unit 7, and step SP
The process ends at 51.

On the other hand, if a negative result is obtained in step SP41, this means that the cancel key 13
Is not pressed, indicating that the telephone directory screen has not been cancelled, and the CPU 20 proceeds to step SP42.

At step SP42, the CPU 20
It is determined whether or not the jog dial 9 has been pressed.
If an affirmative result is obtained in step SP42, this means that the jog dial 9 has been pressed and the item being selected has been selected and determined. The CPU 20 proceeds to step SP52 and moves on to the count value Co of the jog counter.
unt is set to "0", and the routine goes to the next step SP53, where the destination telephone number corresponding to the selected item (destination name) is read from the RAM 22, and displayed on the display unit 7 as a detailed screen together with the destination name. And step SP5
The process ends in 3.

On the other hand, if a negative result is obtained in step SP42, this means that the jog dial 9 has not been pressed and the selected item has not been selected, and the CPU 20 proceeds to step SP43. Move on.

In step SP43, the CPU 20
It is determined whether or not the jog dial 9 has been rotated.
If a positive result is obtained in step SP43, this indicates that the jog dial 9 has been rotated, and the CPU 20 proceeds to step SP44.

In step SP44, the CPU 20
It is determined whether the jog dial 9 has been rotated in the same direction as the previous time. If a negative result is obtained in step SP44, this indicates that the jog dial 9 has been rotated in the opposite direction to the previous operation, and the CPU 40 proceeds to step SP59 to count the count value Co of the jog counter.
After setting unt to "1", the high-speed automatic scroll mode is terminated and the process returns to the automatic scroll mode processing procedure of the routine RT2.

Thus, in the mobile phone 1, by rotating the jog dial 9 in the reverse direction in the high-speed automatic scroll mode, the high-speed automatic scroll mode can be canceled and the automatic scroll mode can be restored.

On the other hand, if a positive result is obtained in step SP44, this indicates that the jog dial 9 has been rotated in the same direction as the previous time, that is, that the jog dial 9 has been continuously rotated in the automatic scroll mode. Then, the CPU 20 proceeds to step SP45 and adds “1” to the count value Count of the jog counter, and then proceeds to step SP46.

In step SP46, the CPU 20
The timer C (not shown) for measuring the reference time of the continuous rotation operation of the jog dial 9 in the high-speed automatic scroll mode is started, and the routine goes to the next step SP47.

In step SP47, the CPU 20 determines
It is determined whether or not the count value Count of the jog counter is “11” or more. If a negative result is obtained in step SP24, this means that the count value Count is "1".
1 ”, and the CPU 40 proceeds to step SP48.

In step SP48, the CPU 20
The items are continuously read out from the RAM 22 and are automatically scroll-displayed at a speed twice as high as the count value of the reference speed, and the process returns to step SP41.

On the other hand, if a positive result is obtained in step SP47, this means that the count value Count is equal to or more than "10", and the CPU 20 moves to step SP60 and sets the count value Count to the limit value. Is set to "10", and the routine goes to step SP48.

When the rotation operation is repeated in the high speed automatic scroll mode, the count value Count becomes "1".
The scroll speed of the high-speed automatic scroll display increases accordingly.

On the other hand, if a negative result is obtained in step SP43, this means that the jog dial 9 has not been rotated, and the CPU 20 proceeds to step SP55.

At step SP55, the CPU 40 determines
It is determined whether the timer C is running. Step S
If an affirmative result is obtained in P55, this indicates that the timer C is running, that is, that the reference time has not elapsed since the last rotation operation in the high-speed automatic scroll mode. The process moves to SP48, and high-speed automatic scroll display is performed.

On the other hand, if a negative result is obtained in step SP55, this means that the timer C is not running, that is, whether the rotation operation has not yet been performed in the high-speed automatic scroll mode or since the previous rotation operation has been performed. This indicates that the reference time has elapsed, and the CPU 20 proceeds to step SP56.

In step SP56, the CPU 20
The count value Count of the jog counter is decremented by "1", the timer C is started in step SP57, and the next step SP
Move to 58.

Thus, when the rotation operation is interrupted in the high-speed automatic scroll mode, the count value Count decreases by "1", and the scroll speed of the high-speed automatic scroll display gradually decreases accordingly.

In step SP58, the CPU 20 sets
It is determined whether or not the count value Count of the jog counter is “5” or more. If a positive result is obtained in step SP58, this means that the count value Count of the jog counter is "5" or more, and the CPU
At step SP48, high speed automatic scroll display is performed.

On the other hand, if a negative result is obtained in step SP58, this means that the count value Count of the jog counter is less than “5”,
The CPU 20 ends the high-speed automatic scroll mode and returns to the automatic scroll mode processing procedure of the routine RT2.

As described above, in the high-speed automatic scroll mode, when the jog dial 9 is rotated in the same direction within the reference time of the timer C, the CPU 20 as the high-speed switching means increases the count value Count of the jog counter by "1". On the other hand, if the jog dial 9 is not rotated within the reference time of the timer C, the count value Count of the jog counter is decremented by "1".

As described above, since the mobile phone 1 starts the automatic scroll display in response to the continuous rotation operation of the jog dial 9, it is possible to easily search for an item by a simple operation.

In the automatic scroll mode, when the continuous rotation operation of the jog dial 9 is repeated a predetermined number of times or more in the automatic scroll mode, the CPU 20 shifts to the high-speed automatic scroll mode, and performs high-speed automatic scrolling at a speed corresponding to the number of continuous rotation operations. Display.

As described above, the mobile phone 1 increases the scroll speed in accordance with the repetition of the continuous rotation operation of the jog dial 9, so that the scroll speed can be controlled by a simple operation, and the item can be searched more quickly. Thus, it is possible to give a realistic operation feeling as if the scroll display is accelerated by the continuous rotation operation of the jog dial 9.

The CPU 20 of the mobile phone 1 returns to the normal scroll mode when the jog dial 9 is rotated in the reverse direction in the automatic scroll mode, and automatically operates when the jog dial 9 is rotated in the reverse direction in the high-speed automatic scroll mode. Return to scroll mode.

As described above, the mobile phone 1 returns to the scroll mode by simply rotating the jog dial 9 in the reverse direction, so that the mobile phone 1 has a realistic operational feeling as if the scroll display is stopped or decelerated by the reverse rotation operation of the jog dial 9. Can be given.
