Abstract

A portable terminal has a portable terminal main body and an enclosure. If the enclosure is open, and if the portable terminal is in a communicating state after a power switch has been turned on, a memo mode is selected which makes it possible to take memos by input from a display panel using a pen. As a result, a memo-mode display image appears on the display, whereby it becomes possible to take memos during communication. In a portable terminal having a window formed in an enclosure, a normal-mode image is displayed as a result of the power switch being turned on even when the enclosure is closed. If the closure is open, and if the portable terminal is in a communicating state, the memo mode is selected.

Claims

1. A portable terminal having a radio communication function, comprising:

a display panel having an image display section and a digitizer disposed on the image display section;

a portable terminal main body equipped with the display panel;

an enclosure attached to the portable terminal main body so as to be able to open and close;

enclosure open/closed state detecting means for detecting an open state of the enclosure; and

communicating state detecting means for detecting a communicating state of the portable terminal, wherein if the enclosure open/closed state detecting means detects the open state of the enclosure, and if the communication state detecting means detects a communicating state of the portable terminal, a memo mode is selected which makes it possible to take memos by input from the display.

2. The portable terminal according to claim 1, further comprising switching means for cancelling the memo mode by means of a user'"'"'s operation when an operation mode of the portable terminal is the memo mode.

3. The portable terminal according to claim 1, wherein a display on the display panel is terminated when the enclosure is in a closed state.

4. The portable terminal according to claim 2, wherein a display on the display panel is terminated when the enclosure is in a closed state.

5. A portable terminal having a radio communication function, comprising:

a display panel having an image display section and a digitizer disposed on the image display section;

a portable terminal main body equipped with the display panel;

an enclosure attached to the portable terminal main body so as to be able to open and close;

enclosure open/closed state detecting means for detecting an open state of the enclosure;

communicating state detecting means for detecting a communicating state of the portable terminal; and

receiving-end detection means for detecting that the portable terminal is a receiver when in a communicating state, wherein if the enclosure open/closed state detecting means detects the open state of the enclosure, if the communicating state detecting means detects the communicating state of the portable terminal, and if the receiving-end detecting means detects that the portable terminal is a receiver, a memo mode is selected which makes it possible to take memos by input from the display.

6. The portable terminal according to claim 5, further comprising switching means for cancelling the memo mode by means of a user'"'"'s operation when an operation mode of the portable terminal is the memo mode.

7. The portable terminal according to claim 5, wherein a display on the display panel is terminated when the enclosure is closed.

8. The portable terminal according to claim 6, wherein a display on the display panel is terminated when the enclosure is closed.

9. A portable terminal having a radio communication function, comprising:

a display panel having an image display section and a digitizer disposed on the image display section;

a portable terminal main body equipped with the display panel; and

an enclosure which has a window and is attached to the portable terminal main body so as to be able to open and close, wherein when the power of the portable terminal is turned on, it is possible to carry out origination and receipt of calls even when the enclosure is closed by indicating on the display panel an image for a normal mode, in which at least the origination and receipt of telephone calls can be conducted, and by indicating display keys for at least carrying out the origination and receipt of calls within the window of the enclosure.

10. The portable terminal according to claim 9, wherein the operation mode is switched to the normal mode when the enclosure changes from an open state to a closed state, so that a normal-mode image is displayed.

11. The portable terminal according to claim 9, further comprising switching means for cancelling the memo mode by means of a user'"'"'s operation when the operation mode is the memo mode.

12. The portable terminal according to claim 9, further comprising enclosure open/closed state detecting means for detecting an open state of the enclosure, and wherein when the enclosure open/closed state detecting means detects the open state of the enclosure, a memo mode is selected which makes it possible to take memos by input from the display.

13. The portable terminal according to claim 12, wherein the operation mode is switched to the normal mode when the enclosure changes from an open state to a closed state, so that a normal-mode image is displayed.

14. The portable terminal according to claim 12, further comprising switching means for cancelling the memo mode by means of a user'"'"'s operation when the operation mode is the memo mode.

15. The portable terminal according to claim 9, further comprising enclosure open/closed state detecting means for detecting an open state of the enclosure, and communicating state detecting means for detecting a communicating state of the portable terminal, and wherein if the enclosure open/closed state detecting means detects the open state of the enclosure, and if the communicating state detecting means detects the communicating state of the portable terminal, a memo mode is selected which makes it possible to take memos by input from the display.

16. The portable terminal according to claim 15, wherein the operation mode is switched to the normal mode when the enclosure changes from an open state to a closed state, so that a normal-mode image is displayed.

17. The portable terminal according to claim 15, further comprising switching means for cancelling the memo mode by means of a user'"'"'s operation when the operation mode is the memo mode.

18. The portable terminal according to claim 15, wherein an area in which normal-mode display keys are displayed when the enclosure is closed is set so as to become smaller than an area in which the normal-mode display keys are displayed when the enclosure is open.

19. The portable terminal according to claim 9, further comprising enclosure open/closed state detecting means for detecting an open state of the enclosure, communicating state detecting means for detecting a communicating state of the portable terminal, and receiving-end detection means for detecting that the portable terminal is a receiver when in a communicating state, and wherein if the enclosure open/closed state detecting means detects the open state of the enclosure, if the communicating state detecting means detects a communicating state of the portable terminal, and if the receiving-end detecting means detects that the potable terminal is a receiver, a memo mode is selected which makes it possible to take memos by input from the display.

20. The portable terminal according to claim 19, wherein the operation mode is switched to the normal mode when the enclosure changes from an open state to a closed state, so that a normal-mode image is displayed.

21. The portable terminal according to claim 19, further comprising switching means for cancelling the memo mode by means of a user'"'"'s operation when the operation mode is the memo mode.

22. The portable terminal according to claim 19, wherein an area in which normal-mode display keys are displayed when the enclosure is closed is set so as to become smaller than an area in which the normal-mode display keys are displayed when the enclosure is open.
