ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a portable wireless information terminal apparatus such as a portable telephone and the like, and more particularly to a portable wireless information terminal apparatus in which a view of a display unit and an operation of an operational section are easy to perform even during using.
2. Description of the Related Art
In a case of a conventional portable wireless information terminal apparatus represented by a portable telephone, as shown in
FIG. 1
, a terminal main body unit
50
has a configuration in which an upper casing
51
and a lower casing
52
are foldably disposed through a hinge
53
. The upper casing
51
is provided with a receiver unit
54
and a display unit
55
. The lower casing
52
is provided with a transmitter unit
56
and a key operation section
57
.
In such a portable wireless information terminal apparatus, the display unit
55
is provided on a side of the upper casing
51
having the receiver unit
54
. Thus, the display unit
55
is concealed by the side of the face of a user during calling. Therefore, information displayed on the display unit
55
can not be viewed.
In order to solve the above mentioned problem of the conventional portable wireless information terminal apparatus, a telephone in which information displayed on a display unit can be viewed even during calling is proposed in Japanese Laid-Open Utility Model Application (JU-A-Showa 61-134159).
FIG. 2
is a rear side appearance view which shows the telephone described in this Japanese Laid-Open Utility Model Application (JU-A-Showa 61-134159).
FIG. 3
is a front side appearance perspective view which shows the telephone.
As shown in FIG.
2
and
FIG. 3
, in the telephone described in Japanese Laid-Open Utility Model Application (JU-A-Showa 61-134159), a receiver unit
61
and a transmitter unit
62
are provided on the front side of a terminal main body unit
60
, and a display unit
63
and an operational section
64
are provided on the rear side thereof.
Then, as shown in
FIG. 3
, a second display unit
65
is further provided on the lower end side of the transmitter unit
62
of the terminal main body unit
60
.
According to the telephone having such a configuration described in Japanese Laid-Open Utility Model Application (JU-A-Showa 61-134159), a user can view the second display unit
65
, if tilting the terminal main body unit
60
so as to separate the side of the transmitter unit
62
from his mouth, without separating the receiver unit
61
from his ear. Thus, the information identical to that displayed on the display unit
63
can be viewed from the second display unit
65
while calling.
In the telephone described in Japanese Laid-Open Utility Model Application (JU-A-Showa 61-134159), the second display unit
65
can be viewed while calling. However, the operational section
64
is located on the rear side of the terminal apparatus. Thus, this results in a problem that the operational section
64
can not be operated while viewing the display units
65
,
63
, during calling.
Especially, since the above mentioned operation of the operational section
64
can not be performed, the screen operations of the display units
63
,
65
and the like can not be performed during calling. Hence, the retrieval of the information within the terminal and the like can not be performed while calling, which is extremely inconvenient for the user.
The second display unit
65
is attached to the position adjacent to the transmitter unit
62
. Therefore, even if the side of the transmitter unit
62
is separated from his mouth, the second display unit
65
is concealed behind his jaw and the like. This results in a problem that the visibility is not always excellent. In this case, this problem may be solved if placing the second display unit
65
at a position away from the transmitter unit
62
and further making the size larger. However, if so, the terminal main body unit
60
becomes larger, which is inconvenient for the utilization as the portable terminal apparatus.
Moreover, the transmitter unit
62
is separated from the mouth during calling. This results in a problem that it is difficult to input voice to the transmitter unit
62
.
Another technique is disclosed in Japanese Laid-Open Utility Model Application (JU-A-Heisei 3-111045). This technique relates to a telephone apparatus installed in a movable body. The telephone apparatus is characterized by comprising: a movable body mount unit installed in the movable body; a handset unit connected to the movable body mount unit having a first display unit for giving information to a user; and a second display unit connected to at least one of the movable body mount unit and the handset unit. Then, the second display unit is described to be disposed such that the displaying direction thereof is adjustable.
However, if the second display unit is disposed in the handset unit, the handset unit is accordingly made larger. Thus, this is not suitable for the portable wireless information terminal apparatus of the prevent invention. Moreover, in the technique disclosed in Japanese Laid-Open Utility Model Application (JU-A-Heisei 3-111045), the operational section is concealed by the side of the user during using. Thus, the operational section can not be operated while viewing the display unit.
SUMMARY OF THE INVENTION
The invention is made to solve the above problems in the conventional technique. Therefore, an object of the present invention is to provide a portable wireless information terminal apparatus, which can easily view a display unit and operate an operational section even during using the terminal apparatus and especially operate the operational section simultaneously while viewing the display unit during calling.
In order to achieve an aspect of the present invention, a portable wireless information terminal apparatus includes a terminal main body unit having a receiver unit and a transmitter unit and a data display unit which is movably provided on the terminal main body unit.
The data display unit may be slidably engaged with the terminal main body unit. Also the data display unit may be tiltably provided on the terminal main body unit.
In order to achieve another aspect of the present invention, a portable wireless information terminal apparatus includes a terminal main body unit having a receiver unit and a transmitter unit, a movable body which is movably provided on the terminal main body unit. In this case, the movable body includes an operational section for operating the terminal main body unit and a data display unit.
An infrared ray communication may be performed between the terminal main body unit and the data display unit. Also the data display unit may be moved along a communication path of the infrared ray communication when being moved into the terminal main body unit.
The terminal main body unit may include a receiver unit mount section on which the receiver unit is provided, a transmitter unit mount section on which the transmitter unit is provided. In this case, the data display unit may be moved such that the data display unit is moved into and out from a portion closer to the transmitter unit mount section than the receiver unit mount section in the terminal main body unit.
The terminal main body unit has at least two sides provided to substantially oppose to each other. In this case, the transmitter unit is disposed closer to a first side than a second side among the two sides in the terminal main body unit. Also the data display unit may be slidable in a direction such that the data display unit is further spaced from the first side.
