Here, obtaining a negative result in step SP3 means that an operation command other than a link command such as simply switching the page image displayed on the first display panel 4 at this point in time to turn the page is used. Is given, and in this case, the CPU 6 executes a process based on the operation command and returns to step SP2.

On the other hand, obtaining a positive result in step SP3 means that, for example, the second image closely related to the page image (that is, the first link image) displayed on the first display panel 4 at this time. It means that a link image display command (link command) has been given, and in this case C
The PU 6 proceeds to step SP4 and reads the corresponding page image data D2 from the RAM 9 based on the link command.

Next, the CPU 6 proceeds to step SP5 and sends out the page image data D2 read out from the RAM 9 to the second display controller 11 via the system bus 7, whereby the second display controller 11
The page image data D is displayed on the second display panel 5 through the
2 is displayed.

In addition, when adding predetermined information to the first and / or second link image based on the link command, the CPU 6 adds the predetermined information to the first and / or second link image in this step SP5. Perform processing.

Then, the CPU 6 thereafter proceeds to step SP6
To determine whether or not the power switch has been turned off. If the power switch is not turned off and a negative result is obtained, the process returns to step SP2. In response, the power switch is turned off and a positive result is obtained. Then, the process proceeds to the next step SP7, where the link image display processing procedure RT1
