<Information processing in display device 100>

Next, information processing of display device 100 according to the present embodiment will be described with reference to FIG. The processor 111 of the display device 100 executes the following processes according to the program in the memory 112 . The following describes the processing of completed TODO items while any TODO list page is being displayed, eg, page 4.

First, as shown in FIG. 2, the processor 111 detects a touch on the check box 150G of the completed TODO item via the touch pad 141, and receives a completion command (step S102).

The processor 111 stores the current date and time as the completion date and time of the item in the TODO data 112A of the memory 112, and displays the completion date and time 150H in the TODO list of the touch panel 150 (step S104). The user may terminate the current process with this. In this embodiment, only the date is displayed as the completion date and time 105H, but both the date and time may be displayed, or only the time may be displayed.

Processor 111 detects touch of function button 150A on touch panel 150, and accepts an instruction to move to the archive page of the completed item (step S106). For example, when function button 150A is pressed, processor 111 displays on touch panel 150 a button for moving the checked item or the currently selected item to the archive page. When the button is pressed, processor 111 displays a window for obtaining confirmation of the item movement, as shown in FIG.

When processor 111 obtains confirmation of the movement (step S108), in page data 112B, it registers the checked item in association with the page of the archive (step S110).

In this embodiment, as shown in FIG. 8, the electronic paper 131 is updated from the screen of the original TODO list page to a screen in which the moved items are deleted (step S112). More specifically, the items that have been moved are deleted, and the remaining items are moved upward (upset).

However, the specifications may be such that the moved items remain on the original TODO list page.
For example, it may be left on the page while being grayed out.

Note that when the processor 111 accepts a touch operation on the page forward button 150X for advancing the page and moves to the archive page, the items moved from the TODO list page are displayed as shown in FIG. As shown in Figure 9, items moved to a page of the archive fill the archive list from top to bottom. In addition, when the page is moved to the archive page, it may be displayed in order of completion date and time.

In FIG. 9, "page A1" indicating that the currently displayed page is "the first page of the archive pages" is displayed in the page display section. In this way, by making the TODO list page display and the archive page display different, it becomes easier to recognize whether the current page is the TODO list page or the archive page.

More specifically, in this embodiment, as shown in FIGS. 7 and 9, when the user selects multiple items from the TODO list page and collectively moves them to the archive page, processor 111 , the items at the bottom of the archive page are displayed on the archive page, followed by the plurality of items on the TODO list page in the same vertical order.

For example, when a user enters a handwritten image across multiple items in the TODO list, the user checks the multiple items and selects the multiple items to display the multiple items on the archive page. When moved, the items will be displayed on the archive page with the handwritten image as input.

Also, as shown in FIGS. 7 and 9, the processor 111 moves the checked or selected items on the TODO list to pages of the archive with the corresponding information still attached. For example, the processor 111 moves the item with a check mark, moves the item with the date and time checked in the TODO list, that is, with the TODO completion date and time 150H attached, and attaches the important flag 150J. If it is in the state (black star state), it will remain in the attached state (black star state), or if it is in the state where the important flag 150J is not attached (white star state), it will remain in the unattached state (white star state). to move items.

Note that the items displayed on the archive page cannot be rewritten. Therefore, if you want to put the same content in the TODO list again, you can copy the item on the archive page and paste it to the item on the TODO list page.

In addition, it is good also as the following structures. When the processor 111 receives a touch operation on the check box 150G via the touch panel 150 on the page of the archive, it unchecks the check box 150G and displays it again on the touch panel 150, and touches the important flag 150J via the touch panel 150. When the touch operation is received, the importance flag 150J is canceled and displayed on the touch panel 150 again.

In this case, it is also possible to move the items displayed on the archive page to the TODO list. More specifically, during display of an archive page, processor 111 accepts a touch operation on an item on touch panel 150 to select an item. Processor 111 detects touch on function button 150A, and displays on touch panel 150 a button for moving the selected item to the TODO list page. When the button is pressed, a window is displayed to obtain confirmation of the item movement. When the confirmation of the movement is obtained, the processor 111 registers the selected item in the page data 112B in association with the page of the TODO list. At this time, if the important flag 150J is attached, the item is moved with the attached state, and if it is not attached, the item is moved with the attached state.

In such a configuration, processor 111 updates the screen of electronic paper 131 from the original archive page screen to a screen with the selected item deleted. However, the specification may be such that the selected item remains on the original archive page.

In addition, when the processor 111 accepts a touch operation on the return page button 150Y for returning the page and moves to the TODO list page, the processor 111 displays the items moved from the archive page.

More specifically, when a user selects multiple items from a page of the archive and moves them to a page of the TODO list, the processor 111 displays items above and below the page of the archive below the bottom item of the TODO list page. Multiple items will be displayed on the TODO list page in the same order.

For example, when the user selects a handwritten image that is input over a plurality of items and moves the plurality of items to the page of the TODO list, the input handwritten image remains the same as the TODO list. It will appear on the page in the list.

In this case as well, the processor 111 transfers the items selected on the archive page to the TODO list page with information such as presence/absence of a completion check, completion date and time, and status of important flags attached. move. Then, when the processor 111 receives a touch operation on the check box 150G or the importance flag 150J via the touch panel 150, the check box 150G or the importance flag 150J is canceled and displayed on the touch panel 150 again.
<Second Embodiment>

In addition to the above functions, when the processor 111 receives a power OFF command, the processor 111 converts the entire surface of the electronic paper 131 to white while storing the screen information of the electronic paper 131 in the memory 112, and then turns on the power. Turn off. As a result, it is possible to reduce the possibility that others will see the contents of the TODO list displayed on the electronic paper 131 after the power is turned off.

More preferably, when the processor 111 receives the power OFF command, the information on the screen of the electronic paper 131 is stored in the memory 112, the entire surface of the electronic paper 131 is converted to white, and then refreshed. , turn off the power.

In this embodiment, when the power is turned on, the processor 111 reads the information in the memory 112 and causes the electronic paper 131 to display again the image and text displayed on the screen immediately before the power was turned off. .

With such a configuration, the user can easily know that the power has been turned off.
