By operating as described above, when the head of the display character string is being displayed, the character string is displayed without being scrolled for a predetermined period of time, and thereafter, smooth scrolling is started. On the other hand, when the display character string is smoothly scrolled to display the end, the display character string is displayed without being scrolled for a predetermined time and fixed. Since the end of the display character string is displayed in a fixed manner, there is an effect that it is easy for the user looking at the display 4 to recognize the end of the character string by judging the end of the display character string.

In addition, since the head of the display character string is fixedly displayed when it is displayed, and then scrolling is started, there is an effect that the head of the display character string can be easily recognized. Thus, when the display character string is repeatedly displayed, the end of the character string is not connected to the head and the delimiter is not lost.

In particular, as described above, when used in a portable communication device such as a portable telephone, the display 4 is small in order to ensure portability. It becomes easy to see.

In the above embodiment, the case where a character string is displayed has been described. However, the present invention is applicable not only to the case of displaying characters but also to the case of displaying a picture.

Next, based on FIG. 4, the LCD shown in FIG.
An interrupt process when a key operation occurs in the scroll display process will be described.

When the scroll interruption process is started in step S20, it is determined in next step S21 whether or not the key operated by the user is the "*" key.
When the “*” key is operated, “YES” is determined, and the process shifts to step S22. On the other hand, if the “*” key has not been operated, “NO” is determined and step S23 is performed.
