As shown in FIG. 3, the scroll control device 101 of the navigation device according to the present invention includes a display screen 8, a touch operation detector 1 (touch operation detecting means), a pressing force detector 2 (pressing force detecting means), and an ECU 100. And a navigation system 7 (scroll means). The display screen 8 displays map information read from the map data. Then, a touch operation by a contact means such as a finger on the display screen 8 is detected by the touch operation detector 1, and a pressing force accompanying the touch operation is detected by the pressing force detector 2. The contact means is not limited to a finger or the like, but may be any means capable of performing a touch operation such as a stick-shaped dedicated member for a touch operation.

The touch operation detector 1 and the pressing force detector 2 are connected to an ECU 100, and a touch operation signal to the display screen 8 and a pressing force signal at a touch point are transmitted to the EC 100.
It is input to U100. Then, the ECU 100 calculates a scroll control signal for the display screen 8 based on the input signal, and outputs the scroll control signal to the navigation system 7. The navigation system 7 performs a scroll operation on the display screen 8 based on a control signal from the ECU 100. The configuration itself is publicly known and a detailed description thereof will be omitted.

As shown in FIG. 5, the pressing force detector 2 is connected to a pressure-sensitive mat 9 provided in contact with the back side of the display screen 8 and is displayed by a finger 10 of an operator. When the screen 8 is pressed, the pressing force applied to the display screen 8 is detected by the pressure-sensitive mat 9 and output to the pressing force detector 2.

The operation of the first embodiment of the map scroll control device having such a configuration will be described with reference to the control block diagram of FIG. 1 and the control flowchart of FIG.

First, a scroll control device according to a first embodiment of the present invention will be described with reference to FIG. 1. The touch operation detector 1 includes a touch position detection unit (touch position detection unit) 3 and a scroll control unit ( (Scroll speed control means) 6. Accordingly, when a touch operation is performed on the display screen 8 by the operator, a touch operation detection signal is output from the touch operation detector 1 to the touch position detection unit 3 and the scroll control unit 6, and the touch position detection signal is output. Coordinate data indicating the touch position 11b is detected by the detection unit 3 and input to the scroll control unit 6, and the vector direction of the scroll from the center point 11a of the current screen 8a to the touch position 11b which is the center of the scroll screen 8b is determined. Calculated by the scroll control unit 6.

The pressing force detector 2 is connected to a scroll speed setting unit 5 of the ECU 100, and a detection signal of the pressing force detected by the pressing force detector 2 is input to the scroll speed setting unit 5. The scroll speed setting unit 5 is connected to the storage unit 4 and the scroll control unit 6, and the pressing force detector 2
The scroll speed corresponding to the pressing force is set based on the pressing force input from the controller and the scroll speed characteristic diagram stored in the storage unit 4 in advance, and is output to the scroll control unit 6.

The scroll control unit 6 determines the scroll operation of the screen according to the input signal from the touch operation detector 1, the input signal from the touch position detection unit 3, and the input signal from the scroll speed setting unit 5, and the navigation system. 7 is output. Then, the scroll of the screen display 8 is executed in the navigation system 7 based on the scroll operation determined by the scroll control unit 6.

Next, the control operation according to the first embodiment of the present invention will be described with reference to the flowchart of FIG. First, in step S1, it is determined whether or not the current display screen 8 is a map screen, that is, whether or not it is necessary to scroll when a touch operation is input. If it is determined that the current display screen 8 is a map screen, the process proceeds to step S2.
On the other hand, if it is determined that the current display screen 8 is not the map screen, the process returns.

Next, at step S2, the display screen 8 of the touch operation detector 1 is touched (touched) by the operator.
It is determined whether it has been performed. Here, when it is determined that the display screen 8 is touched by the operator, it is determined that scrolling is necessary, and the process proceeds to step S3.
On the other hand, if it is determined that the display screen 8 has not been touched, the process returns to step S1, and a standby state in which steps S2 and S1 are repeated until an operator's touch operation on the display screen 8 is detected in step S2. .

If it is determined in step S2 that the display screen 8 has been touched, and the process proceeds to step S3, the touch position detection unit 3 detects coordinate data indicating a touch position in the display screen 8 and proceeds to step S4.

Next, in step S4, it is determined whether or not a pressing operation is being performed on the pressing force detector 2. Here, the determination in step S4 is made when the pressing operation amount detected by the pressing force detector 2 connected to the pressure-sensitive mat 9 is determined to be larger than the first predetermined value P1 shown in FIG. Is determined that the pressing operation is performed, and the pressing operation amount detected by the pressing force detector 2 is equal to the first predetermined value P1.
When it is determined that the pressing operation is smaller than that, it is determined that the pressing operation is not performed. If it is determined in step S4 that the pressing operation has been performed, the process proceeds to step S5, and the scroll of the display screen 8 in the scroll speed setting unit 5 is set to a high-speed scroll described later. On the other hand, step S4
In step S6, when it is determined that the pressing force is smaller than the first predetermined value P1 and the pressing operation is not performed and the process proceeds to step S6, the normal scroll speed V1 is set in the scroll speed setting unit 5 and the scroll control unit 6 is output. Therefore, if it is determined in step S4 that the pressing force on the display screen 8 detected by the pressing force detecting unit 2 is smaller than a predetermined value (P1 in this embodiment),
A predetermined normal speed scroll (V1 in this embodiment) is set. The first predetermined value P1 is an appropriate value for judging the presence or absence of a conscious pressing operation based on an average pressing force detected when the operator consciously performs the pressing operation. Should be set to.

The high-speed scroll set when it is determined in step S4 that the pressing operation has been performed and the process proceeds to step S5 will be described in detail. First, the pressing force detected by the pressing force detector 2 is determined by the scroll speed. It is input to the setting unit 5. The scroll speed setting unit 5 is connected to a storage unit 4 storing a characteristic diagram showing a relationship between the pressing force and the scroll speed as shown in FIG. 4A or 4B. Is read from the characteristic diagram and output to the scroll speed setting unit 5. Thereby, the scroll speed corresponding to the pressing force in the pressing operation performed on the display screen 8 is set by the scroll speed setting unit 5 and output to the scroll control unit 6.

In the characteristic diagram shown in FIG. 4, (A) shows a case where the scroll speed is set to increase stepwise according to the increase in the pressing force. For example, when the pressing force is equal to or more than the first predetermined value P1. If the pressing force becomes equal to or more than the second predetermined value P2 and the third predetermined value P3, the scroll speed is changed from the initial speed V1 (normal speed scroll) to V2. Speed V2 each
From V3 to V3 and from V3 to V4. In the characteristic diagram shown in FIG. 4, (B) shows a case where the scroll speed is set to be continuously increased in accordance with the increase in the pressing force, and when the pressing force becomes equal to or more than the first predetermined value P1. Indicates that the scroll speed is linearly increased and the pressing force
When the scroll speed exceeds the predetermined value P3, the scroll speed is set to the upper limit value V4. In this embodiment, the scroll speed (V2, V2) is higher than the normal speed scroll V1.
3, V4) are collectively referred to as high-speed scrolling.

The characteristic diagram of the pressing force and the scroll speed may be set in advance to one of the characteristic diagrams shown in FIGS. 4A and 4B, or may be set according to the preference of the operator. Alternatively, both characteristics may be switched. In addition, the characteristic diagram is not limited to only the stepwise or continuous characteristics as described above, and the stepwise or continuous characteristics are combined, and in the region where the pressing force is low, the characteristic is stepwise or continuous. In a region where the pressing force is high, continuous characteristics or the like may be used. Further, as the characteristic that the scroll speed changes continuously, not only the characteristic that changes linearly as shown in FIG. 4B, but also the characteristic that changes in a quadratic function or the characteristic that changes exponentially. It is good.

Next, in step S7, the presence / absence of a touch operation is determined again by the touch operation detector 1. When it is determined that the touch operation is performed, the process returns to step S4, and while the touch operation is detected, the control from step S4 to step S7 is repeated. Therefore, while the touch operation is being performed by the operator, the pressing force is always detected by the pressing force detector 2, and the scrolling speed is converted to the scroll speed according to the pressing force. On the other hand, step S
If it is determined that the touch operation has not been performed by 7, it is determined that the operator has released the hand from the display screen 8, the process proceeds to step S <b> 8, and the process returns after stopping scrolling.

In the navigation system 7 according to the first embodiment, detection signals from the touch operation detector 1 constituting the touch operation detecting means and the pressing force detector 2 constituting the pressing operation amount detecting means are used as scroll speed controlling means. When the detected value detected by the pressing force detector 2 is equal to or greater than a predetermined value, the scroll speed is controlled to be higher than the scroll speed V1 at the beginning of the touch operation. By continuously performing two operations of touching and pressing (pressing) the display screen 8 as it is, it is possible to eliminate the inconvenience of the operation in which the normal scroll has to be performed within a certain time from the start of the scroll as in the related art. The scroll is switched to the high-speed scroll quickly and in a short time from the start of the scroll.

Also, according to the first embodiment, the pressing force of the display screen 8 is reduced to be smaller than the first pressing force P1 from the time of high-speed scroll pressing the display screen 8, so that the normal pressing force is reduced. Since the scroll speed can be returned to the scroll speed V1, it is not necessary to cancel the touch operation once and interrupt the scroll operation, the scroll speed switching operation is performed continuously, and the operability of the scroll control device 101 is improved. I do.

In the first embodiment, the description has been made by using the map display of the navigation device as the vehicle information display device. However, the present invention is not limited to this, and a scroll operation of the screen is required. If applicable, they can be applied. That is, even when a vertical scrolling operation is required on the search candidate location display screen, the menu display screen, the received mail display screen, or the like, the touch operation detector 1 and the pressing force detector 2 are used in the same manner as in the first embodiment. The scroll speed is controlled based on the detection value at.

Next, a second embodiment of the present invention will be described with reference to FIGS. The detailed description of the same configuration as that of the first embodiment is omitted.

In the second embodiment of the present invention, the overall configuration and control block diagram of the scroll control device are the same as the overall configuration and control block diagram of the scroll control device of the first embodiment shown in FIGS. It is. And FIG.
When the pressing force associated with the pressing operation is input from the pressing force detector 2 to the scroll speed setting unit 5 as shown in FIG. 6, the input is performed based on the characteristic diagram of the pressing force and the scroll speed stored in the storage unit 4. The scroll speed corresponding to the set pressing force is set and input to the scroll control unit 6. When the input scroll speed is equal to or higher than the predetermined value and the touch operation by the touch operation detector 1 is no longer detected, the scroll control unit 6 is controlled to maintain the scroll speed. Thereby, the scroll speed becomes equal to or higher than the predetermined value, and when the operator releases his / her finger from the display screen 8, the scroll speed is maintained.

When a touch operation detection signal from the touch operation detector 1 is input again to the scroll control unit 6 while the scroll speed is being held, the scroll control unit 6 causes the touch operation to be performed. It is determined whether or not the touch position on the display screen 8 matches the current scroll direction of the display screen 8, and if it is determined that they do not match, the scroll direction is switched to the direction corresponding to the touch position. That is, as shown in FIG. 9, the pressure-sensitive mat 9 arranged on the back side of the display screen 8 is divided into nine areas, and the correspondence between the position on the display screen 8 and the scroll direction is set in advance. I have. When a touch operation signal is input from the touch operation detector 1 to the touch position detection unit 3, the touch position detection unit 3 detects which area of the display screen 8 has been touched and inputs the area to the scroll control unit 6. Is done. As a result, for example, if the lower right 20 is touch-operated while the scroll toward the right side of the display screen 8 (the right side scroll) is in the scroll speed holding state, the display screen 8 keeps the scroll speed while maintaining the scroll speed. The scroll direction is switched from the scroll to the diagonally lower right.

Next, an operation state according to the second embodiment of the present invention will be described with reference to the flowcharts of FIGS. In the second embodiment, as shown in FIG. 10, two stages of a high speed scroll (first scroll speed) V6 and a normal speed scroll (second scroll speed) V5 are set as the scroll speed. When it is determined that the pressing force detected in Step 2 is equal to or higher than the predetermined pressing force P5, the scroll speed of the display screen 8 is switched from the normal speed scroll V5 to the high speed scroll V6.

When control is started in the flowchart shown in FIG. 6, first, in step S10, it is determined whether or not the current display screen 8 of the navigation system 7 is a map screen.
That is, it is determined whether or not the screen can be scrolled. Here, when it is determined that the display screen 8 is a map screen, the process proceeds to step S20. On the other hand, when it is determined that the display screen 8 is not a map screen, it is determined that it is not necessary to perform the scroll control, and the process returns. I do.

In step S20, the touch operation detector 1
It is determined whether or not the finger of the operator is touching the display screen 8, that is, whether or not a touch operation is being performed. Here, when it is determined that the touch operation has been performed, the process proceeds to step S30, and when it is determined that the touch operation has not been performed, the process proceeds to perform the scroll holding determination described later.

When it is determined in step S20 that the touch operation has been performed and the process proceeds to step S30, it is determined whether or not the touch position detected by the touch position detection unit 3 is the center of the display screen 8. If it is determined that the touch position is at the center of the display screen 8, step S4
The process proceeds to 0, and it is determined whether or not a pressing operation has been performed.
On the other hand, when it is determined that the touch position is not at the center of the display screen 8, that is, when it is determined that a touch operation has been performed on a portion other than the center of the display screen 8, the process proceeds to step S60.

In step S30, the touch position is displayed on the display screen 8.
When the process proceeds to step S40, it is determined by the pressing force detector 2 whether or not a pressing operation has been performed by the operator as described above. And
If it is determined that the pressing operation has been performed, step S5
The program proceeds to 0, returns the map screen displayed on the display device 8 to the previous screen (menu screen in this embodiment), and returns. If it is determined in step S40 that the pressing operation has not been performed, the process returns. Accordingly, when the operator performs the touch operation at the center of the display screen 8 and performs the pressing operation by pushing the center portion as it is,
It is determined that the operator wants to return to the previous screen, and is controlled to return to the menu screen immediately before the map screen. If it is determined in step S30 that the touch position is at the center, the process may directly proceed to step S50 and return to the previous screen.

In the second embodiment, it is determined whether or not a pressing operation is being performed. When the pressing force detected by the pressing force detector 2 is determined to be equal to or more than a predetermined value P5, the pressing operation is performed. It is determined that the operation has been performed, and when the pressing force is smaller than the predetermined value P5, it is determined that the pressing operation has not been performed. It should be noted that a route search button, a route change button, a point registration button, and the like are displayed on the menu screen, and can be selected and operated by an operator so as to be an arbitrary operation screen.

On the other hand, when it is determined in step S30 that the touch position is not at the center of the display screen 8, and the process proceeds to step S60, the scroll operation of the current display screen 8 is in the scroll stop state or in the normal speed scroll state. It is determined whether there is a high-speed scroll state. If it is determined in step S60 that the current display screen 8 is in the scroll stop state, the process proceeds to step S7.
The process proceeds to step S11 when it is determined that the current display screen 8 is in the normal speed scroll state, and to step S11 when it is determined that the current display screen 8 is in the high speed scroll state. Note that the determination of the scroll speed in step S60 is performed by a first normal speed scroll flag F10, a second normal speed scroll flag F11,
It is determined whether or not the high-speed scroll flag F20 is set. That is, in step S60,
Not all the flags are set (F10 = 0,
(F11 = 0, F20 = 0), it is determined that the scroll is stopped, and the process proceeds to step S70. Also, the first
If any one of the normal speed scroll flag F10 and the second normal speed scroll flag F11 is in the set state (F10 = 1 or F11 = 1), it is determined that the normal speed scroll state is set, and the process proceeds to step S11. Further, when the high-speed scroll flag F20 is in the set state (F20 = 1), it is determined that the high-speed scroll state is set, and the process proceeds to.

If it is determined in step S60 that the current display screen 8 is in the scroll stop state, and the process proceeds to step S70, the display screen 8 is changed by the operator from the scroll stop state.
Since the touch operation has been performed on a portion other than the center portion of, the operator determines that the user wants to start scrolling the display screen 8, switches from the scroll stop state to the normal speed scroll state, and returns. At this time, the first normal speed scroll flag F10 set when the scroll is switched from the scroll stop state to the normal speed scroll state is set (F10 = 0 → F10 = 1).

Next, a case where at least the touch operation is maintained by the operator after switching from the scroll stop state to the normal speed scroll state in step S70 and returning as described above will be described. In this case, the process from the start to step S60 is the same as the control described above. In step S60, it is determined that the current scroll display screen 8 is the normal speed scroll, and the process proceeds to step S11.

In step S11, it is determined whether or not a pressing operation has been performed based on an input from the pressing force detector 2.
If it is determined that the pressing operation has not been performed, it is determined that the operator wants to maintain the current normal speed scroll, and the process returns. On the other hand, if it is determined in step S11 that the pressing operation has been performed (the pressing force P5 or more), it is determined that the operator wants to switch from the normal speed scroll to the high speed scroll, and the process proceeds to step S12.

In step S12, it is determined whether the first normal speed scroll flag F10 is in a set state (F10 = 1). Then, when it is determined that the state is the setting state, it is the case where the pressing operation is performed by the operator after shifting from the scroll stop state to the normal speed scroll. Therefore, in this case, the process proceeds to step S13, the display screen 8 is switched from the normal speed scroll to the high speed scroll, and the process returns. When the display screen 8 is switched from the normal scroll state to the high-speed scroll state in step S13, the high-speed scroll flag F20 is set to a set state (F20 = 0 → F20 = 1), and
The first normal speed scroll flag F10 is released (F10 =
1 → F10 = 0).

On the other hand, in step S12, the first normal scroll flag F10 is not set (F10 = 0).
If it is determined, the process returns. (In this case, since the normal speed scroll is determined in the above-described step S60, the second normal speed scroll F11 described later is always set (F11 = 1).) The second normal speed scroll flag F11 set when the scroll is switched to the normal speed scroll.
Is in the set state (F11 = 1), it is determined in step S60 that the scroll is normal speed, and the
The control proceeds to control after step 11, but in step S12 the first
It is determined that the normal speed scroll F10 is not in the set state, and the routine returns with the normal speed scroll. As a result,
After the operator performs the pressing operation from the high-speed scroll state and shifts to the normal speed scroll state, even if the operator still continues the pressing operation, shifts from the normal speed scroll state to the high-speed scroll state again. The hunting phenomenon is prevented.

Next, the case where the touch operation detector 1 determines that the touch operation has not been performed in the above-described step S20 and the process proceeds to the subsequent steps will be described with reference to the flowchart of FIG. It should be noted that the case of proceeding to is that the operator has not operated the display screen 8 at all when the current display screen 8 is a map screen, that the current display screen 8 is in a normal scroll state, This is a case where the operator has released his / her finger from the display screen 8 in the scroll state.

From this case, the process proceeds to step S21, and it is determined whether the first normal speed scroll flag F10 or the second normal speed scroll flag F11 is set. Here, if either the first normal speed scroll flag F10 or the second normal speed scroll flag F11 is in the set state, when the display screen 8 is in the normal speed scroll state, the operator can switch from the display screen 8 to the normal speed scroll flag F10. This is the case where the finger is released, and it is determined that the operator wants to stop the scrolling of the display screen 8, and the process proceeds to step S25 to stop the scrolling operation and return. At this time, the first normal speed scroll flag F10 or the second normal speed scroll flag F11 that has been set is released (F10 = 1 → F10 = 0 or F11 = 1 → F
11 = 0).

On the other hand, if it is determined in step S21 that both the first normal speed scroll flag F10 and the second normal speed scroll flag F11 are not set, the process proceeds to step S22 to determine whether the high speed scroll flag F20 is set. No, that is, whether the current display screen 8 is in the high-speed scrolling state is determined. If it is determined in step S22 that the high-speed scroll flag F20 has not been set, the process directly returns because the current display screen 8 is in the scroll stop state. On the other hand, when it is determined that the high speed scroll flag F20 is in the set state (F20 = 1), the process proceeds to step S23.

In step S23, it is determined whether or not a speed holding flag F30 described later is set (F30 = 1). When the speed holding flag F30 is in the set state, the process returns as it is because the speed holding described later has already been performed. On the other hand, if the speed holding flag F30 is not set, the process proceeds to step S
Proceed to 24.

In step S24, the scroll control unit 6
At the same time, the current high-speed scroll is held, and the speed holding flag F30 is set (F30 = 0 →
F30 = 1) Return. As a result, in step S14 described above, the display screen 8 shifts from the normal speed scroll state to the high speed scroll state, and the scroll speed becomes equal to or higher than a predetermined value (V6 in this embodiment).
When the operator releases his / her finger from the display screen 8, the high-speed scroll state of the display screen 8 is maintained.

Next, the case where it is determined in step S60 that the current scroll state of the display screen 8 is the high-speed scroll state and the process proceeds to step S60 will be described with reference to the flowchart shown in FIG. The process proceeds to the scroll stop state, the normal speed scroll state, and then the high speed scroll state, or, as described above, after the high speed scroll state is maintained in step S24, the operator displays on the display screen 8. This is a case where a touch operation is performed on the touch panel.

As shown in FIG. 8, when the process proceeds to step S31, the process proceeds to step S31, and it is determined whether or not a pressing operation is performed based on an input from the pressing force detector 2. If it is determined that the pressing operation has been performed, step S32 is performed.
On the other hand, if it is determined that the pressing operation has not been performed, the process proceeds to step S34 to perform a scroll direction switching determination described later.

If it is determined in step S31 that the pressing operation has been performed and the process proceeds to step S32, it is determined whether or not the speed holding flag F30 is set (F30 = 1). Then, when it is determined that the speed holding flag F30 is not set, the process returns as it is. As a result, if it is determined in step S13 that the pressing operation has been performed from the normal scroll state and the state has shifted to the high-speed scroll state, and if the operator continues the pressing operation as it is, the high-speed scroll state is switched in step S32. Since the return is performed while maintaining the state, the high-speed scroll state is continued.

In step S32, the speed holding flag F
If it is determined that 30 is in the set state, the process proceeds to step S33, where the high speed scroll state is switched to the normal speed scroll state. Therefore, when the high-speed scroll state is maintained without the touch operation on the display screen 8, the operator performs the touch operation on the display screen 8 and presses the display screen 8 as it is to perform the pressing operation. In this case, it is determined that the operator wants to release the high-speed scroll holding state and return to the normal speed scroll state, and the display screen 8 is set to the normal speed scroll state. When the high-speed scrolling state is shifted to the normal-speed scrolling state in step S33, the second normal-speed scrolling flag F11 is set (F11 = 0 → F11 = 1), and the high-speed scrolling flag F20 and the speed holding are set. The flag F30 is released (F20 = 1 → F20 = 0, F30 = 1 → F30 =
0).

If it is determined in step S31 that the pressing operation has not been performed and the process proceeds to step S34, the touch position on the display screen 8 in the touch operation performed by the operator in the scroll control unit 6 Is determined to match with the current scroll direction. If the touch position matches the current scroll direction, the process returns to step S32,
If it is determined in step S32 that the current state is the speed holding state, the flow is switched from the high speed scroll state to the normal speed scroll state in step S33. That is, if the operator performs a touch operation on the position on the display screen 8 corresponding to the direction that matches the current scroll direction in the high-speed scroll holding state, it is determined that the pressing operation has not been performed in step S31. Even when the determination is made, the high-speed scroll holding state is released and the state is switched to the normal-speed scroll state.

If it is determined in step S34 that the position of the touch operation performed by the operator on the display screen 8 does not match the current scroll direction, the process proceeds to step S35, and the scroll direction switching unit The scroll direction is switched to the direction corresponding to the touch position on the display screen 8 where the touch operation has been performed by the user 20, and the process returns. Therefore, when the operator performs a touch operation on a position on the display screen 8 corresponding to a direction different from the current scroll direction while the high-speed scroll state is maintained, the high-speed scroll state is maintained. The scroll direction is switched to a direction corresponding to the touch position.

As described above, according to the map scroll control device of the second embodiment of the present invention, when the normal scroll state is shifted to the high-speed scroll state, that is, when the scroll speed is equal to or more than the predetermined value. Is the touch operation detector 1 because the operator has released his / her finger from the display screen 8.
, The scroll speed is maintained even if the touch operation is no longer detected. Therefore, even if the operator wants to maintain the high-speed scroll state, the display screen 8
Does not need to be continuously pressed, and the troublesome operation is reduced.

When the operator performs a touch operation in a direction different from the scroll direction while the high-speed scroll state is maintained, only the scroll direction is switched while maintaining the high-speed scroll state. Sometimes it is not necessary to cancel the scroll operation, and the operability of the scroll control device is improved. On the other hand, if the operator performs a touch operation in a direction that matches the scroll direction while the high-speed scroll state is maintained, the high-speed scroll state is released. If the user wants to cancel, the cancellation is performed relatively easily according to the operator's will, and the operability of the scroll control device is improved.

In the above-described second embodiment, the scroll speed is set to two stages of the normal speed scroll and the high speed scroll. However, the present invention is not limited to this. The scroll speed is changed according to the pressing force as in the first embodiment. The scroll speed may be increased stepwise or continuously. In this case, the maximum scroll speed is set to a predetermined value, and when the scroll speed becomes maximum with an increase in the pressing force, the speed is maintained.

In the second embodiment, it is determined that the high-speed scroll is held and the pressing operation detected by the pressing operation amount detector 2 is equal to or more than a predetermined value, and the pressing operation is performed. In such a case, or when a high-speed scroll speed is held and a position on the display screen 8 that matches the scroll direction is touched, the high-speed scroll holding is released, but the high-speed scroll state is maintained. When the touch operation is detected by the touch operation detector 3, the high-speed scroll holding may be released regardless of the touch position on the display screen 8 associated with the touch operation. Further, the configuration may be such that the normal speed scroll state is maintained when the high speed scroll state is released. In addition, as shown in FIGS. 11A and 11B, a configuration may be adopted in which hysteresis is provided in the characteristics of the pressing force and the scroll speed to prevent hunting accompanying switching of the scroll speed.
