  FIG. 2 is a block diagram showing the internal configuration of the screen display unit shown in FIG. 1 together with its peripheral configuration. In the figure, the same reference numerals as those in FIG. 1 denote the same blocks as those shown in FIG.

  The screen display unit 2 includes a display memory 21, a display content update unit 22, a display control unit 23, and a display monitor 24.

  The display contents are written in the display memory 21 by the main control unit 1 and have a storage capacity corresponding to the display area of the display monitor 24 such as a liquid crystal display.

  The display content update unit 22 is connected to the main control unit 1 via the internal bus 20 and is scrolled by a single operation of a scroll key that arrives via the key operation unit 5 based on the control of the main control unit 1. According to the set number of lines, the display contents are updated to scroll the contents of the display area.

  The display control unit 23 is also connected to the main control unit 1 via the internal bus 20, and based on the control of the main control unit 1, the contents of the old display area displayed immediately before by one operation of the scroll key And a function of performing an identification display for visually recognizing the boundary of the contents of the new display area that is updated and displayed by a single operation of the scroll key.

  Examples of identification display by the display control unit 23 include line display, boundary display by mark display (FIGS. 4A and 4B, respectively), or one display area as shown in FIGS. On the other hand, display processing such as a change in background color, character color, character font, etc. (FIGS. 5A, 5B, 5C, respectively) can be considered. By performing the processing in this way, the user can easily recognize the boundary between the contents of the old display area and the contents of the new display area mixedly displayed on the screen, and can read the contents.

  The display control unit 23 cooperates with the main control unit 1 and the clock / timer unit 8 to detect the elapse of a predetermined time (identification display release timer) or the operation of a new scroll key as described above. Release the identification display.

  Also, when it is detected that the scroll operation is continuously performed within a certain time (continuous operation determination timer) which is shorter than the predetermined time (identification display release timer), a new scroll key operation is detected. It also performs control to invalidate the release of the identification display due to the fact Details will be described with reference to the flowchart shown in FIG.

  FIG. 3 is a flowchart quoted for explaining the scroll control method by the portable terminal device of the present invention. Specifically, the mobile terminal device according to the present invention is realized by sequentially reading and executing a program recorded in the memory unit 9.

  The operation of the portable terminal device of the present invention shown in FIGS. 1 and 2 will be described in detail below with reference to the flowchart shown in FIG.

  First, the main control unit 1 checks whether or not the user has performed a scroll operation with the scroll key via the key operation unit 5 (S31). Here, when the scroll operation is detected, the display content updating unit 22 updates the display memory 21 according to the scroll line setting. Then, the display content is read from the display memory 21 by the display control unit 23, and scroll display is performed (S32).

  Here, it is assumed that the part that is newly displayed on the screen is displayed as an identification display area in distinction from others, such as by changing the background color (S33). Further, the main control unit 1 activates the clock / timer unit 8 to start timing by the “continuous operation determination timer” and the “identification display release timer” (S34).

  Here, the “identification display cancellation timer” is provided to cancel the identification display by monitoring the elapse of a predetermined time from when the user confirms the identification display until the content is read.

  In addition, the “continuous operation determination timer” usually releases the identification display until a predetermined time elapses or when there is a new scroll operation, but earlier than the timer threshold set here. When the scroll key is continuously pressed, the identification display so far disappears immediately and cannot be followed visually. Therefore, the identification display is provided for a while.

  Normally, the “continuous operation determination timer” value <the “identification display release timer” value, where the former is 1.0 second and the latter is 5.0 seconds.

  Next, it is checked whether or not there is a further scroll operation (S35). Here, if it is confirmed that the scroll operation has not been performed (No in S35), the time-up of the continuous operation determination timer is checked (S36).

  Here, when time-up is detected (Yes in S36), the presence / absence of a new scroll operation is checked (S37). Here, when there is no new scroll operation (No in S37), the time-up of the identification display release timer is checked (S38), and when the time-up has been reached (S38 Yes), an example is shown in FIG. 4 or FIG. Is terminated (S39), and the process is terminated. If the time has not been reached (No in S38), the process returns to S37.

  When a new scroll operation is detected in S37 (S37 Yes), normally, the display of the recognized display area is canceled, but here the cancellation is invalidated, and the display content update unit according to the display scroll line setting 22, the display memory 21 is updated. Then, the display content updated by the display content update unit 22 is read from the display memory 21 by the display control unit 23, and scroll display is performed (S40).

  Next, the previous identification display area is canceled, and the part that newly appears on the screen is displayed as the identification display area (S41). Then, the “continuous operation determination timer” and the “identification display release timer” are updated (S42), and the process returns to S35.

  On the other hand, when a further new scroll operation is detected in the process of S35 (S35 Yes), the display content updating unit 22 updates the display memory 21 according to the scroll line setting. Next, the display content is read from the display memory 21 by the display control unit 23, and scroll display is performed (S43). Then, the part newly appearing on the screen by scrolling is added to the identification display area so far and displayed (S44). Finally, the “continuous operation determination timer” and the “identification display release timer” are updated (S42), and the process returns to S35.

  An example of the identification display is shown in FIGS. FIG. 4A shows an example in which line display is performed as an identification display at the boundary between the old display area and the new display area. Here, three new lines appear below the line by the first scroll. Then, five new lines set by the second scroll appear. FIG. 4B shows an example in which the identification display is indicated by a ▲ mark.

  5A is an example of changing the background color of one display area, FIG. 5B is an example of changing the text color of one display area, and FIG. 5C is an example of changing the background color of one display area. This is an example of changing the character font.

  In the above description, the scroll in the vertical direction has been described. However, when the scroll in the horizontal direction is performed, if the number of columns scrolled by one operation is set, the identification display can be performed in the same manner as described above.
