After moving the scroll bar 23, the control unit 10 determines whether or not the second touch operation is released (step S14).

(1) When the second touch operation is released After the scroll bar 23 is moved in step S13, the user does not want to scroll the electronic book image 24, and it is assumed that the index finger is released from the portion 44. When the touch panel 12 no longer detects the second touch operation, the control unit 10 determines that the second touch operation has been released (YES in step S14), and moves the scroll bar 23 to the first position. (Step S18). After returning the scroll bar 23 to the first position, the control unit 10 returns to the process of step S11.

(2) When only the first touch operation is released After the scroll bar 23 is moved in step S13, the user assumes that the thumb is released from the portion 42 while the portion 44 is still touched by the index finger. When the touch panel 12 no longer detects the first touch operation and only the second touch operation is detected, the control unit 10 first determines that the second touch operation has not been released (in step S14). NO), and further, it is determined that the first touch operation has been released (YES in step S15), and acceptance of the slide operation on the knob 22 via the touch panel 12 is permitted (step S16). After permitting the acceptance of the slide operation, the control unit 10 waits until the second touch operation is released (NO in step S17).

In this state, it is assumed that the user has performed a slide operation in the first direction X on the knob 22 in order to display the image of the desired page in the electronic book image 24 in the display area 25. In this case, when the touch panel 12 detects the above slide operation, the control unit 10 moves the knob 22 until the knob 22 is displayed at the slide position, and at the same time, the position of the knob 22 after the movement in the electronic book image 24.

When the desired page is displayed in the display area 25 by scrolling the electronic book image 24, the user releases the index finger from the portion 44. When the second touch operation is no longer detected by the touch panel 12, the control unit 10 determines that the second touch operation has been released (YES in step S17), and displays the scroll bar 23 on the display unit 11. It is moved to the position of 1 (step S18). After returning the scroll bar 23 to the first position, the control unit 10 returns to the process of step S11.

After the movement of the scroll bar 23 in step S13, while the first touch operation and the second touch operation are maintained, the control unit 10 determines that the second touch operation has not been released. (NO in step S14), it is determined that the first touch operation has not been released (NO in step S15), and the process of step S13 is repeated.

As described above, since the electronic book image 24 includes 100 pages of images, the length of the knob 22 in the first direction X is 1/100 of the length of the main body 21 in the first direction X. It becomes. Therefore, the display area of the knob 22 displayed on the display unit 11 is smaller than the area of the user's finger. In such a case, it becomes difficult for the user to directly touch the knob 22.

However, according to the above embodiment, the control unit 10 provides the display unit 11 with a scroll bar 23 including a main body 21 extending along the first direction X and a knob 22 arranged on the main body 21. It is displayed at a predetermined first position. When the control unit 10 receives the first touch operation on the display area 25 and the second touch operation on the main body portion at the same time via the touch panel 12, the control unit 10 gives the display unit 11 a second touch operation. The scroll bar 23 is moved from the first position so that the knob 22 is displayed at the second position where the above is performed.

As a result, by performing the first touch operation and the second touch operation, the user grasps the position where the knob 22 is displayed and moves his / her finger to that position with respect to the knob 22. The knob 22 can be selected without directly performing the touch operation. Therefore, even when the display area of the knob 22 is small, the user can easily perform a touch operation on the knob 22.

Further, according to the above embodiment, the control unit 10 displays when the second touch operation is released after receiving the first touch operation and the second touch operation at the same time via the touch panel 12. The scroll bar 23 is moved to the first position by the unit 11. As a result, the user can easily return the scroll bar 23 to its original position and display it.

Further, according to the above embodiment, when the control unit 10 receives the first touch operation and the second touch operation via the touch panel 12 at the same time, the first touch operation with respect to the knob 22 via the touch panel 12 is performed. Acceptance of slide operation in direction X is prohibited. After receiving the first touch operation and the second touch operation at the same time via the touch panel 12, the control unit 10 permits the acceptance of the slide operation when only the first touch operation is released. As a result, it is possible to prevent the slide operation on the knob from being erroneously accepted while the knob is being selected.

Further, according to the above embodiment, the control unit 10 causes the display unit 11 to display a part of the electronic book image 24 together with the scroll bar 23 in the display area 25 in which the scroll bar 23 is not displayed. Regarding the length of the first direction X, the control unit 10 has the same ratio of the length of the display portion to the length of the electronic book image 24 and the ratio of the length of the knob 22 to the length of the main body 21. With respect to the position of the first direction X, the scroll bar 23 is displayed so that the position of the knob 22 on the main body 21 corresponds to the position of the display portion on the electronic book image 24.

When the control unit 10 receives the slide operation of the first direction X with respect to the knob 22 via the touch panel 12, the control unit 10 moves the knob 22 until the knob 22 is displayed at the slide position on the display unit 11, and also moves the knob 22 to the electronic book image. The electronic book image 24 is scrolled in the first direction X until the portion corresponding to the position of the knob 22 after the movement in 24 is displayed in the display area 25. As a result, the user can easily display the desired image by sliding the knob 22.
