The pad portion 53 is a switch on the entire surface and can detect depression and release. The pad unit 53 is a pressure-sensitive device that can rotate infinitely clockwise or counterclockwise, and can detect the direction and amount of rotation.

  Next, processing when an operation with the circular scroll pad 52 is performed in the mobile phone according to the present embodiment will be described with reference to FIGS.

  First, the operation of scrolling the screen by operating the circular scroll pad 52 will be described with reference to FIG.

  The input unit 50 waits for the circular scroll pad 52 to be pressed (step S401). When the circular scroll pad 52 is pressed (step S401 / YES), the input unit 50 waits for the rotation of the circular scroll pad 52 (step S402). When the rotation of the circular scroll pad 52 is detected (step S402 / YES), the input unit 50 determines whether the circular scroll pad 52 has rotated clockwise or counterclockwise, and the rotation direction is determined as a working memory. 30 (step S403). In the mobile phone according to the present embodiment, it is possible to instruct screen scrolling by rotating the circular scroll pad 52 while pressing the circular scroll pad 52. When the circular scroll pad 52 is stopped being pressed, it is instructed to stop the screen scrolling operation.

  The CPU 10 measures the rotation amount of the circular scroll pad 52, and stores the measured rotation amount in the work memory 30 (step S404). Further, the CPU 10 calculates the accumulated rotation amount after the circular scroll pad 52 starts rotating, and stores it in the work memory 30 as the accumulated rotation amount (step S405).

  Then, the CPU 10 determines whether or not the accumulated rotation amount stored in the work memory 30 has reached an amount worth moving by one line of screen scroll (step S406). If it is determined that the accumulated rotation amount has reached an amount worth moving for one line of screen scroll (step S406 / YES), the CPU 10 converts the accumulated rotation amount into a movement amount for scrolling the screen by one line (step S407). .

  When the accumulated rotation amount is converted into the screen scroll movement amount for one line, the CPU 10 reads the rotation direction stored in step S403 from the work memory 30, and determines whether the rotation direction is clockwise or counterclockwise. Judgment is made (step S408). If the rotation direction is clockwise (step S408 / clockwise), the screen is scrolled downward by one line on the screen displayed on the display unit 60 (step S409). On the other hand, if the rotation direction is counterclockwise (step S408 / counterclockwise), the screen displayed on the display unit 60 is scrolled upward by one line (step S410).

  Next, processing from when screen scrolling is started by the processing shown in FIG. 4 to when automatic screen scrolling is started will be described with reference to FIG.

  While the rotation of the circular scroll pad 52 is continued, the CPU 10 always monitors the accumulated rotation amount from the start of the rotation of the circular scroll pad 52 calculated in step S405 of FIG. It is determined whether or not has exceeded one round (step S501).

  If it is determined that the accumulated amount of rotation has exceeded one turn (step S501 / YES), the CPU 10 first checks whether or not the circular scroll pad 52 is continuously pressed (step S502). Here, when the pressing on the circular scroll pad 52 has been released (step S502 / NO), the shift to the automatic screen scroll operation is not performed, and the screen scroll operation is also ended (step S506).

  On the other hand, if the circular scroll pad 52 has been continuously pressed (step S502 / YES), the rotation direction stored in the work memory 30 in step S403 in FIG. 4 is read and the rotation direction is clockwise. Or it is judged whether it is counterclockwise (step S503). If the rotation direction is clockwise (step S503 / clockwise), automatic screen scrolling in the downward direction of the screen displayed on the display unit 60 is started (step S504). On the other hand, if the rotation direction is counterclockwise (step S503 / counterclockwise), automatic screen scrolling upward on the screen displayed on the display unit 60 is started (step S505). When the automatic screen scrolling is started, the scrolling of the screen is continued even if the user stops rotating the circular scroll pad 52. At that time, it is assumed that the user does not need to rotate the circular scroll pad 52, but continuously presses the circular scroll pad 52.

  In the embodiment shown in FIG. 5, the automatic screen scrolling is started when the user rotates the circular scroll pad 52 by one turn. However, as shown in FIG. 6, the circular scroll pad 52 is 1 + 1. It is good also as a structure by which an automatic screen scroll is started when it rotates by / 4 round. Therefore, it is possible to have a configuration in which the user can arbitrarily set how many times the circular scroll pad 52 is rotated to start the automatic screen scrolling. In that case, the revolution set by the user is stored in the work memory 30, and the CPU 10 reads the stored revolution and compares it with the cumulative rotation amount calculated in step S405 of FIG. An automatic screen scrolling is started when the set number of laps is exceeded.

  Next, the operation for stopping the automatic screen scrolling started in step S503 or step S504 in FIG. 5 will be described with reference to FIG.

  When automatic screen scrolling is being executed while the circular scroll pad 52 is continuously pressed, the input unit 50 monitors whether or not the circular scroll pad 52 is pressed (step S701). When the release of the circular scroll pad 52 is detected by the input unit 50 (step S701 / NO), the CPU 10 stops the automatic screen scrolling started in step S503 or step S504 shown in FIG. 5 (step S706).

  On the other hand, when the pressing of the circular scroll pad 52 is continued by the input unit 50 (step S701 / YES), the input unit 50 waits for detection of the rotation operation of the circular scroll pad 52 (step S702). If rotation of the circular scroll pad 52 is not detected (step S702 / NO), the CPU 10 continues the automatic screen scroll operation.

  When the rotation of the circular scroll pad 52 is detected by the input unit 50 (step S702 / YES), the CPU 10 measures the rotation amount of the circular scroll pad 52 and stores the measured rotation amount in the work memory 30 (step S702). S703). The CPU 10 calculates the accumulated amount of rotation after the circular scroll pad 52 starts rotating, and stores it in the work memory 30 as the accumulated amount of rotation (step S704).

  Then, the CPU 10 determines whether or not the accumulated rotation amount stored in the work memory 30 has reached an amount worth moving by one line of screen scroll (step S705). When it is determined that the accumulated rotation amount has reached an amount worth moving for one line of screen scroll (step S705 / YES), the CPU 10 stops the automatic screen scroll operation (step S706). On the other hand, when it is determined that the accumulated rotation amount has not reached the amount worth moving for one line of screen scroll (step S705 / NO), the CPU 10 continues the automatic screen scroll operation.

  In step S705, whether to stop or continue the automatic screen scrolling is determined based on whether or not the cumulative rotation amount calculated in step 704 has reached an amount worth moving for one line of screen scrolling. However, the stop or continuation of the automatic screen scrolling may be determined based on whether or not the cumulative rotation amount has reached an amount equivalent to the movement of two lines of screen scrolling, and the user can arbitrarily set the configuration. It is.

  Further, in the process shown in FIG. 7, the automatic screen scrolling is stopped by releasing the pressing of the circular scroll pad or rotating the circular scroll pad while the automatic screen scrolling is being executed. However, the stop or continuation of the automatic screen scrolling can be determined by the process shown in FIG. In FIG. 8, as in FIG. 7, an operation for stopping the automatic screen scrolling started in step S503 or step S504 in FIG. 5 will be described.

  When automatic screen scrolling is being executed while the circular scroll pad 52 is continuously pressed, the input unit 50 monitors whether or not the circular scroll pad 52 is pressed (step S801). When the release of the circular scroll pad 52 is detected by the input unit 50 (step S801 / NO), the CPU 10 stops the automatic screen scrolling started in step S503 or step S504 shown in FIG. 5 (step S808).

  On the other hand, when the pressing of the circular scroll pad 52 is continued by the input unit 50 (step S801 / YES), the input unit 50 waits for detection of the rotation operation of the circular scroll pad 52 (step S802). If rotation of the circular scroll pad 52 is not detected (step S802 / NO), the CPU 10 continues the automatic screen scroll operation.

  When the rotation of the circular scroll pad 52 is detected by the input unit 50 (step S802 / YES), the CPU 10 detects the rotation direction of the circular scroll pad 52 and stores the detected rotation direction in the work memory 30 (step). S803). Further, the CPU 10 measures the rotation amount of the circular scroll pad 52 and stores the measured rotation amount in the work memory 30 (step S804). At the same time, the CPU 10 calculates the accumulated amount of rotation after the circular scroll pad 52 starts rotating, and stores it in the work memory 30 as the accumulated amount of rotation (step S805).

  Then, the CPU 10 determines whether or not the accumulated rotation amount stored in the work memory 30 has reached an amount worth moving by one line of screen scroll (step S806). If it is determined that the accumulated rotation amount has reached the amount worth moving for one line of screen scroll (step S806 / YES), the CPU 10 reads the rotation direction stored in the work memory 30 in step S803, and the rotation direction is It is determined whether or not the rotation direction is the same as that stored in the work memory 30 in step S403 of FIG. 4 (step S807). When the rotation direction stored in step S803 and the rotation direction stored in step S403 are the same (step S807 / YES), the CPU 10 stops the automatic screen scroll operation. (Step S808). On the other hand, if the rotation direction stored in step S803 differs from the rotation direction stored in step S403 (step S807 / NO), the CPU 10 changes the scrolling direction to the opposite direction by the automatic screen scrolling. The operation is continued (step S809).

  According to the above-described configuration, a mobile phone having a pressure-sensitive circular scroll pad that automatically rotates the screen while rotating the circular scroll pad while pressing the circular scroll pad and then stopping the rotation operation. The automatic screen scrolling stop function can be assigned to the start function, and the automatic screen scrolling can be continued while the circular scroll pad is continuously pressed, and the screen scrolling can be stopped by stopping the pressing or newly starting the rotating operation of the circular scroll pad. By assigning to, it is possible to easily add an automatic screen scroll start function and a stop function without affecting the normal scroll operation.

  Next, the operation of a mobile phone according to another embodiment will be described. Note that the specific configurations of the mobile phone and the circular scroll pad are the same as the configurations of FIGS. 1, 2, and 3 described in the above-described embodiment, and thus description thereof is omitted here. The operation for stopping the automatic screen scrolling is also the same as the processing shown in FIG.

  First, the operation of scrolling the screen by operating the circular scroll pad 52 will be described with reference to FIG.

  The input unit 50 waits for the circular scroll pad 52 to be pressed (step S901). When the circular scroll pad 52 is pressed (step S901 / YES), the input unit 50 waits for the rotation of the circular scroll pad 52 (step S902). When the rotation of the circular scroll pad 52 is detected (step S902 / YES), the input unit 50 determines whether the circular scroll pad 52 has rotated clockwise or counterclockwise, and the rotation direction is determined as a working memory. 30 (step S903). In the mobile phone according to the present embodiment, it is possible to instruct screen scrolling by rotating the circular scroll pad 52 while pressing the circular scroll pad 52. When the circular scroll pad 52 is stopped being pressed, it is instructed to stop the screen scrolling operation.

  The CPU 10 measures the rotation amount of the circular scroll pad 52 and stores the measured rotation amount in the work memory 30 (step S904). Further, the CPU 10 calculates the accumulated rotation amount after the circular scroll pad 52 starts rotating, and stores it in the work memory 30 as the accumulated rotation amount (step S905). Further, the CPU 10 calculates the rotation speed of the circular scroll pad 52 from the elapsed time since the circular scroll pad 52 started rotating and the accumulated rotation amount stored in the work memory 30, and stores it in the work memory 30. Store (step S906).

  Then, the CPU 10 determines whether or not the accumulated rotation amount stored in the work memory 30 has reached an amount worth moving by one line of screen scroll (step S907). If it is determined that the accumulated rotation amount has reached an amount worth moving for one line of screen scroll (step S907 / YES), the CPU 10 converts the accumulated rotation amount into a movement amount for scrolling the screen by one line (step S908). .

  When the accumulated rotation amount is converted into the screen scroll movement amount for one line, the CPU 10 reads the rotation direction stored in step S903 from the work memory 30, and determines whether the rotation direction is clockwise or counterclockwise. Judgment is made (step S909). If the rotation direction is clockwise (step S909 / clockwise), the screen is scrolled downward by one line on the screen displayed on the display unit 60 (step S910). On the other hand, if the rotation direction is counterclockwise (step S909 / counterclockwise), the screen displayed on the display unit 60 is scrolled upward by one line (step S911).

  Next, processing from when screen scrolling is started by the processing shown in FIG. 9 to when automatic screen scrolling is started will be described with reference to FIG.

  If it is determined that the accumulated amount of rotation has exceeded one turn (step S1001 / YES), the CPU 10 first checks whether or not the circular scroll pad 52 is continuously pressed (step S1002). Here, if the pressing on the circular scroll pad 52 has already been released (step S1002 / NO), the transition to the automatic screen scroll operation is not performed, and the screen scroll operation is also ended (step S1007).

  On the other hand, when the circular scroll pad 52 is continuously pressed (step S1002 / YES), the CPU 10 reads the rotation speed stored in step S905 of FIG. 9 (step S1003). Further, the CPU 10 reads the rotation direction stored in step S903 in FIG. 9 and determines whether the rotation direction is clockwise or counterclockwise (step S1004). If the rotation direction is clockwise (step S1004 / clockwise), an automatic screen downward on the screen displayed on the display unit 60 at a speed corresponding to the rotation speed read in step S1003. Scrolling is started (step S1005). On the other hand, when the rotation direction is counterclockwise (step S1004 / counterclockwise), the screen displayed on the display unit 60 is moved upward at a speed corresponding to the rotation speed read in step S1003. Automatic screen scrolling is started (step S1006). When the automatic screen scrolling is started, the scrolling of the screen is continued even if the user stops rotating the circular scroll pad 52. At that time, it is assumed that the user does not need to rotate the circular scroll pad 52, but continuously presses the circular scroll pad 52.

  Next, the operation of controlling the screen scrolling speed by tilting the mobile phone by the user when the automatic screen scrolling operation is performed will be described with reference to FIG.

  When automatic screen scrolling is being executed while the circular scroll pad 52 is being pressed, the input unit 50 monitors whether the circular scroll pad 52 is being pressed (step S1201). When the release of the circular scroll pad 52 is detected by the input unit 50 (step S1201 / NO), the CPU 10 stops the automatic screen scrolling started in step S503 or step S504 shown in FIG. 5 (step S1206).

  On the other hand, when the pressing of the circular scroll pad 52 is continued by the input unit 50 (step S1201 / YES), the gyro sensor 110 waits for the user to tilt the mobile phone itself (step S1202). When the tilt of the mobile phone is detected by the gyro sensor 110 (step S1202 / YES), the CPU 10 determines that the tilted direction is the front direction (FIG. 13) in a state where the surface of the mobile phone is directed to the user side. Or the depth direction (shown in FIG. 14) is determined (step S1203).

  When the mobile phone is tilted forward (step S1203 / frontward), when the screen is scrolling downward by the automatic screen scrolling operation, the CPU 10 increases the scrolling speed and the automatic screen scrolling is performed. When the screen is scrolling upward due to the operation, the CPU 10 reduces the scrolling speed (step S1204). On the other hand, when the direction in which the mobile phone is tilted is the depth direction (step S1203 / depth direction), when the screen is scrolling downward by the automatic screen scrolling operation, the CPU 10 reduces the scrolling speed and automatically When the screen is scrolling upward by the screen scroll operation, the CPU 10 increases the scrolling speed (step S1205).

  According to the above configuration, when the mobile phone is equipped with a gyro sensor and the automatic screen scroll operation is being performed, when the tilt of the mobile phone is detected by the gyro sensor, the screen scroll by the automatic screen scroll operation is performed. The screen scrolling speed can be easily changed even during the operation. In this embodiment, when the mobile phone is tilted in the front direction or the depth direction with the surface of the mobile phone facing the user, the screen scroll speed is accelerated or decelerated. The direction of tilting is not limited to the front direction or the depth direction. Therefore, it is also possible to adopt a configuration in which the screen scrolling speed is accelerated or decelerated by tilting the mobile phone to the left or right side with the surface of the mobile phone facing the user. Further, in the present embodiment, when the mobile phone is tilted in the front direction or the depth direction with the surface of the mobile phone facing the user, the screen scroll speed is accelerated or decelerated. It is possible for the user to arbitrarily set the direction of acceleration or deceleration when tilted in any direction. Furthermore, it is also possible to adopt a configuration in which the screen scrolling speed is accelerated or decelerated in multiple stages according to the angle at which the mobile phone is tilted.
