ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a mobile information terminal equipment, more particularly, to a mobile radio wave communication equipment, such as a mobile telephone, furnished with functions including electronic note, data communication, word processor, personal computer, and so on.
Moreover, the present invention relates to the communication control and user interface of a terminal for which the mobile radio wave communication equipment such as a mobile telephone and personal information management functions are combined.
Furthermore, the present invention relates to the structure of a cover for protecting an input display unit for the portable electronic apparatus such as a mobile information terminal equipment.
BACKGROUND OF THE RELATED ART
As a conventional mobile information terminal equipment furnished with functions of a mobile telephone plus an electronic note, there is a mobile information terminal equipment disclosed in the official gazette of Japanese Unexamined Patent Publication No. HEI 5-211464 of Japan Patent Application. The outline of the Patent Publication No. HEI 5-211464 is given below.
FIG.
58
and
FIG. 59
show the appearance of the conventional mobile information terminal equipment.
In
FIG. 58
, a body
1
of a mobile information terminal equipment, an antenna
2
, a speaker
3
, a liquid crystal display
4
, a microphone
5
, a telephone keyboard
6
, and a cover
7
are illustrated.
FIG. 59
gives another front view with cover
7
opened, showing an electronic note keyboard
8
and a cover switch
9
.
Telephone keyboard
6
for dialing keys is placed on the top of cover
7
installed on a mobile information terminal equipment body
1
. Electronic note Keyboard
8
for character data input keys is installed from the back of cover
7
to the area covered by cover
7
. A telephone mode and an electronic note mode are switched based on the output from a cover switch
9
, which detects the opened/closed status of cover
7
. When the cover is closed, the telephone mode is set, enabling the user to use the equipment as a regular mobile telephone. Meanwhile, the electronic note mode is set as the cover is opened, thus allowing the user to use it as an ordinary electronic note.
FIG. 60
shows the memory configuration for storing electronic note data of the mobile information terminal equipment. The memory is the Random Access Memory (RAM) and incorporated in mobile information terminal equipment body
1
(not shown in FIG.
58
and FIG.
59
).
A telephone directory data memory
10
, a schedule data memory
11
, and a memorandum data memory
12
are illustrated in FIG.
60
.
Telephone directory data memory
10
stores a name and a telephone number input from electronic note keyboard
8
as a pair. Schedule data memory
11
stores the activities input from electronic note keyboard
8
and the planned time and date for starting and ending each activity as a triad. Memorandum data memory
12
stores data input from electronic note keyboard
8
collectively.
FIG. 61
,
FIG. 62
, and
FIG. 63
show examples of screens displayed on liquid crystal display
4
. Character strings are displayed on three lines on the screen. Line
1
shows a selected function, a mode name, and status information, and etc. Line
2
and line
3
show data input from telephone keyboard
6
or electronic note keyboard
8
, and data read from the RAM (not shown).
In telephone mode, e.g., when the cover is closed, a “TEL”
13
indicating telephone mode and a mark
14
for receiving sensitivity appear on line
1
. A dialed data “0367895421”
15
input by pressing the numeric keys on telephone keyboard
6
is displayed on line
3
(FIG.
61
).
When the cover is opened, e.g., in electronic note mode, and in telephone directory data search mode, “TEL.NO. SEARCH”
16
is displayed on line
1
. On line
2
, a retrieved data, a name “YAMADA TARO”
17
is displayed and on line
3
, its telephone number “03-6789-5421”
18
is displayed, respectively (FIG.
62
). Displayed data is retrieved from telephone directory data memory
10
shown in
FIG. 60
of the RAM (not shown) incorporated in mobile information terminal equipment body
1
. When the cover is opened, data can be easily retrieved, input, modified, deleted, etc. using electronic note keyboard
8
which has alphabetic keys, kana keys, and so forth.
When the cover is closed in the status shown in
FIG. 62
, telephone mode starts and “TEL”
13
and mark
14
for receiving sensitively are added to the display at line
1
(FIG.
63
). Pressing the S (SEND) key at this status enables the user to actually dial the displayed telephone number, because it is in telephone mode.
In this way, the mobile information terminal equipment disclosed in the official gazette Japanese Unexamined Patent Publication No. HEI 05-211464 is a mobile telephone set having an electronic note function for facilitating the input of character data by installing the operation keys for electronic note on both the rear sides of the opening/closing part attached to the main cabinet and on the body surface covered with the opening/closing part.
Another example of the conventional mobile information terminal equipment is disclosed in Japanese Unexamined Patent Publication No. HEI 06-284067 of Japan Patent Application. The mobile information terminal equipment is a mobile telephone with functions for a word processor or a personal computer.
FIG.
64
and
FIG. 65
are the front views showing the appearance of the conventional mobile information terminal equipment.
FIG. 64
is the front view showing cover
7
in the closed status while
FIG. 65
shows the front view of cover
7
in the opened status.
In
FIG. 65
, a hinge
19
is shown. For the conventional mobile information terminal equipment, cover
7
and mobile information terminal equipment body
1
are overlapped in parallel with the plane in the front view. Mobile information terminal equipment body
1
is coupled with cover
7
by hinge
19
, which can hold the cover at a necessary position from the closed status to the opened status.
When the mobile information terminal equipment is used as a mobile telephone, as shown in
FIG. 64
, mobile information terminal equipment body
1
is overlapped with cover
7
, and used with cover
7
in the closed status. The power source key P on telephone keyboard
6
is pressed. When there is a call-in, pressing down the send key S on telephone keyboard
6
enables a telephone talk. Furthermore, pressing down the one-touch key D on telephone keyboard
6
makes corresponding dial signals to be automatically transmitted, thus allowing a call-out. When a talk ends, the ending talk key E on telephone keyboard
6
is pressed.
To dial manually for a call-out, after the power source key P is pressed, cover
7
is opened. Then, a send key (not shown) of electronic note keyboard
8
is pressed, and the dial number is input from dial keys (not shown) of electronic note keyboard
8
. After that, cover
7
is closed, and talking is enabled when the equipment is entered to a talk mode.
When using as a word processor or a personal computer, after the power source key P on telephone keyboard
6
is pressed with the cover in the closed status, cover
7
is opened, and with cover
7
in the opened status, designated keys (not shown) of electronic note keyboard
8
are operated to activate the application. Operating the input mode selection keys (not shown) of electronic note keyboard
8
to select either a kana or roman character input mode renders it possible to function as a word processor or to input necessary data into a personal computer. Moreover, input characters can be displayed on liquid crystal display
4
so that the input data can be confirmed.
FIG. 66
is a flowchart showing the execution of a processor (not shown) incorporated in mobile information terminal equipment body
1
. The program shown in this flowchart is stored in the ROM incorporated in mobile information terminal equipment body
1
.
The processor periodically detects whether or not an input has been
