When the decision key for confirming the selected item is operated in any one of Steps -53, the content (telephone number or e-mail address) of the selected item where the cursor 50 is located is selected and determined.

During activation of the portable telephone device, the man-machine interface control unit 40 periodically detects operation signals from the X-axis direction scroll operation unit 3 and the Y-axis direction scroll operation unit 4 for scroll operation. I do. When an operation signal from the X-axis direction touch pad 10 is detected,
When a scroll operation is detected to be rightward or leftward, and when an operation signal from the Y-axis direction touch pad 7 is detected, it is determined whether the scroll operation is upward or downward. Then, based on an operation signal from the X-axis direction touch pad 10 or the Y-axis direction touch pad 7, a scroll amount is grasped, information such as telephone directory information stored in the memory 24 is read out as appropriate, and scrolled on the display unit 2. Display the display screen. The operation mode of the scroll operation such as the scroll amount and the scroll speed with respect to the operation amount of the operation unit is controlled based on the setting information stored in the memory 41.

After that, when the operation signal continues for a predetermined time and detects that a contact or a pressing operation is performed for a predetermined time or more, a state in which a high-speed scroll is continuously performed in a direction corresponding to the operated key as a long-press operation. Is displayed, and scrolling is continued until the long press operation is completed.

Next, the procedure of the scroll operation as described above will be described with reference to the flowcharts of FIGS. The processing related to the control of the scroll operation is mainly performed in the man-machine interface control unit 40. FIG. 6 is a flowchart illustrating a processing procedure for detecting operation signals from the X-axis direction scroll operation unit and the Y-axis direction scroll operation unit.

The man-machine interface controller 40
Is in an event waiting state as in step S11 at the time of startup, and waits for an event related to a scroll operation to occur. Then, in the processing after step S12, the operation signal of the scroll related operation is detected and the processing corresponding thereto is performed. In step S12, it is determined whether or not an operation signal due to the slide operation of the Y-axis direction touch pad 7 is detected (Y-axis direction operation detection). If the Y-axis direction slide operation signal is detected, in step S13,
Scrolling in the Y-axis direction is performed as Y-axis direction sliding processing corresponding to this operation. In step S14, it is determined whether or not an operation signal due to a slide operation of the X-axis direction touch pad 10 has been detected (X-axis direction operation detection).
In step S15, scrolling in the X-axis direction is executed as X-axis direction sliding processing corresponding to this operation.

In step S16, it is determined whether or not an operation signal due to contact or pressing of the upper automatic scroll key 6 has been detected (upward automatic scroll operation detection). If an upward key operation signal has been detected, step S17 is performed. Then, as the upper automatic scrolling process corresponding to this operation, one-stage scrolling in the upward direction or high-speed scrolling is executed. In step S18, it is determined whether or not an operation signal due to contact or pressing of the lower automatic scroll key 8 has been detected (lower automatic scroll operation detection). If a lower key operation signal has been detected, the process proceeds to step S19. As the lower automatic scroll processing corresponding to this operation, one-step scrolling in the downward direction or high-speed scrolling is executed. Further, in step S20, it is determined whether or not an operation signal due to contact or pressing of the right automatic scroll key 11 has been detected (right automatic scroll operation detection). If a rightward key operation signal has been detected, the process proceeds to step S21. As a right automatic scroll process corresponding to this operation, one-step scroll or high-speed scroll in the right direction is executed. Step S2
In 2, it is determined whether or not an operation signal due to contact or pressing of the left automatic scroll key 9 has been detected (left automatic scroll operation detection). If a left key operation signal has been detected, this operation is performed in step S23. As a left automatic scroll process corresponding to the above, one-step scroll or high-speed scroll in the left direction is executed. If no operation signal related to each of the above-mentioned scroll operations is detected, step S
Returning to step 12, the detection of the operation signal is repeated periodically, and the standby state of the scroll operation is continued.

FIG. 7 is a flowchart showing a processing procedure relating to the Y axis direction sliding processing, and FIG. 8 is a flowchart showing a processing procedure relating to the X axis direction sliding processing. When the operation signal by the slide operation of the Y-axis direction touch pad 7 is detected, as shown in FIG. 7, the Y-axis direction slide processing is started in step S31, and the fixing on the Y-axis direction touch pad 7 is performed in step S32. It is determined whether the position has been touched or pressed for a long period of time equal to or longer than a predetermined time, that is, whether a long press operation has been performed at the fixed position. Here, if the operation is a long press operation at the fixed position, an additional function process registered in advance is executed in step S33.

The additional function processing includes "scroll function on / off switching", "key lock on / off switching", "ringtone / vibrator switching" and the like. Set. “Switching of scroll function on / off” is for turning on / off the activation of the scroll function by a set operation. The “key lock on / off switching” is for turning on / off a key lock function for invalidating a key operation by a set operation. The “switching of ringtone / vibrator” is a so-called manner mode on / off setting for switching between generation of a ringtone and vibration of the vibrator as a notification operation at the time of an incoming call by a set operation.

If it is determined in step S32 that the operation is not the long press operation at the fixed position, then in step S34, Y
It is determined whether or not the operation is an upward sliding operation on the axial touch pad 7. Here, in the case of an upward sliding operation, an upward scroll on the display screen is executed so as to scroll and display the upward items on the display screen of the display unit 2 in step S35. Step S34
If the operation is not an upward sliding operation, it is determined in step S36 whether or not the operation is a downward sliding operation on the Y-axis direction touch pad 7. If the operation is a downward sliding operation, the display unit 2 is determined in step S37. Is scrolled downward on the display screen so as to scroll down the items on the display screen.

When an operation signal due to a slide operation of the X-axis direction touch pad 10 is detected, in steps S41 to S47 of FIG.
Execute scrolling in the X-axis direction. That is, if the operation is a long-press operation at the fixed position, an additional function process registered in advance is executed in step S43, and if the operation is a rightward slide operation, the rightward item is displayed on the display screen of the display unit 2 in step S45. Is scrolled rightward on the display screen so as to scroll the display. If the operation is a leftward slide operation, the leftward scroll on the display screen of the display unit 2 is scrolled on the display screen of the display unit 2 in step S47. Perform a scroll in the direction.

Execute scroll display in direction. When an operation signal due to the contact or pressing operation of the left automatic scroll key 9 is detected, high-speed scrolling or one-step scrolling in the left direction is executed in steps S81 to S84 in FIG. . That is, if the operation is a long press operation, a high-speed scrolling display in the left direction is executed on the display screen of the display unit 2 in step S83, and if the operation is a single press operation, one step of left scroll is performed on the display screen of the display unit 2 in step S84. Execute scroll display in direction.

Next, a modified example of the scroll operation section will be described. FIG. 13 is a plan view showing a configuration of a modification of the display unit and the scroll operation unit. In the first example shown in FIG. 13A, the X and X are defined at the lower edge and the left edge of the display unit 2.
Only the X-axis direction touch pad 62 and the Y-axis direction touch pad 61 are arranged as the axial direction scroll operation unit 3 and the Y axis direction scroll operation unit 4, respectively. Also,
In the second example shown in FIG. 13B, the left automatic scroll key 65 is used as the X-axis direction scroll operation unit 3 and the Y-axis direction scroll operation unit 4 at the lower edge and the left edge of the display unit 2, respectively. Only the right automatic scroll key 66, the upper automatic scroll key 63, and the lower automatic scroll key 64 are arranged.

The same operation and effect as those of the above-described embodiment can be obtained by the scroll operation section of these modified examples. The scroll operation unit may be provided with a touch pad and an automatic scroll key separately, or may be provided in an integrated manner. The arrangement configuration of the scroll operation unit can be appropriately set according to the design factors (design, specifications, etc.) of the device.

As described above, in the present embodiment, the scroll operation units using the elongated touch pads are separately provided for the X-axis direction and the Y-axis direction. The scroll operation can be easily and reliably performed, the erroneous operation can be prevented, the scroll operation does not become complicated, and the burden on the user during the operation can be reduced. Furthermore, by enabling the additional function to be executed in the touch pad for scroll operation, the scroll operation can be switched on and off as required to be activated, and as a result, current consumption can be suppressed. Also, by assigning and setting additional functions to the scroll operation unit and also using the operation means, the number of keys on the front of the apparatus can be reduced.

In the above embodiment, the X-axis direction and the Y-axis direction
Although the example has been described in which scrolling is performed in the two-dimensional axial direction, when there are few items to be displayed on the screen, scrolling may be performed only in the one-dimensional direction in the X-axis direction or the Y-axis direction. . Also, instead of scrolling in both directions in the X-axis direction and the Y-axis direction,
You may comprise so that it may scroll only in one direction. For example, in the Y-axis direction, scrolling is performed only in one direction, such as scrolling only from the top to the bottom of the display screen and returning to the top from the bottom item. It may be configured such that only scrolling in one direction is performed in the left or right direction.

In the scroll operation, the characters and symbols of the display items are moved up, down, left and right, and the cursor is displayed at a predetermined position by inverting black and white to display the selection items. However, other operations are also applicable. It is possible. For example, when the cursor is moved to a character or the like of a display item, only the display item is moved with the cursor fixed, or both are movable, and the scroll amount is small (eg, one-step scroll), the cursor is moved. When the scroll amount is large, the display items can be moved.
