As shown in the side view of FIG. 1B, a jog dial 1 for selecting various application functions on a display screen 17 of the display device 6 is provided on the left side surface of the housing body 2.
4 are provided.

The lid 3 is foldable with respect to the housing body 2 via a hinge 8, and a display device 6 such as an LCD is provided inside the lid 3. Therefore, when the lid 3 is folded in the normal state, the display device 6 is built in the lid 3 and is reduced in size as shown in FIG. 2B.

FIG. 3 is an exploded perspective view of the hinge 8 of the portable telephone of this embodiment. The hinge 8 is provided with a central bearing portion 8c between two left and right bearing portions 8a and 8b formed integrally with the housing body 2 with a synthetic resin or the like, and these bearing portions 8a, 8b, 8 are provided.
The left and right shafts 8e and 8f are inserted into the through holes 8d formed in the left and right shafts 8a and 8f, as shown by arrows AA 'in FIG. Is rotatable.

A through hole 8d is provided substantially at the center of the center bearing 8c.
An L-shaped through hole 8g is drilled so as to be orthogonal to, and a pipe 8h is inserted so as to loosely fit into the L-shaped upper through hole 8g. It is configured to be rotatable in the direction B '. In this case, the tip of the pipe 8h is fixed to the bottom 3a of the lid 3.

As another method, the pipe 8h is erected so as to be fixed to the central bearing 8c, and the tip of the pipe 8h inserted into the through hole 8j formed in the bottom 3a of the lid 3 is attached to the lid 3. On the other hand, they are pivotally connected so as to be rotatable in the direction of arrows BB '.

In this manner, when pivotally mounted in the BB 'direction so as to be rotatable, the ball embedded in the through hole 8g or 8j at a predetermined angle, not shown in FIG. The lid 3 is configured to be able to rotate by 180 ° with respect to the housing body 2.

A wire 16 connected from the housing body 2 to the lid 3 is connected to a through hole 8g of the central bearing 8c via a pipe 8h.

With the hinge 8 as described above, the lid 3
FIG. 2 (C) shows a state in which the display device 6 is being rotated completely 180 ° and is provided inside the lid portion 3 on the front side of the housing body 2. 2A, and the state where the lid part 3 is folded is shown in FIG.
Is shown in

In the case of FIG. 2A, the screen 17 of the display device 6
2 is reversed as compared with the case of FIG.
Numeral 7 is electrically inverted so that a normal screen 17 can be viewed in the use state of FIG.

FIG. 4 shows a model of a videophone that performs video distribution via a transmission path 23 such as a narrowband or wideband ISDN network or the Internet using the above-described mobile phone 1 which is a mobile terminal device of the present invention. .

A video input from an imaging camera 11 such as a CCD disposed on the back side of the housing body 2 is codeced by a moving image or still image codec unit 18, and is transmitted via a transmission control unit 20 and a line interface 21. The data is transmitted to the transmission path 23 by wire or wirelessly via the antenna 7. In this case, a video to be distributed is displayed on the display device 6 as a screen 17. The text information and the video screen transmitted from the videophone 24 are also displayed on the display device 6.

The audio signal from the transmitter 13 is also codec-coded by the audio codec 19 and transmitted to the transmission line 23 via the transmission control unit 20 and the line interface 21. The system control unit 22 controls the image codec unit 18 and the audio codec unit 19, and the transmission control unit 20 controls the system control unit 22. The system control unit 22 inputs various types of text information via the operation unit 4 such as a numeric keypad.

The jog dial 14 is rotatable with a fingertip, for example, clockwise (CW). When the jog dial 14 is pressed downward (D), the switching means 26 is turned on or turned on. Is generated through the waveform shaping circuit 25, and the waveform-shaped pulse is supplied to the system control unit 22. The system control unit 22 determines a predetermined item according to the pulse generation density within a certain period, for example, the number of pulses. A switching pulse is output for each list, and the selection item displayed on the display device 6 is selected.

When the transmission path 23 is the Internet, I
As in the case of a network such as SDN, the transmission band is not guaranteed and the transmission speed is low (10 to 120 kb).
ps) and has jitter, so video and audio signals are compressed and coded to several hundredths, then multiplexed into one stream, and a buffer or the like is provided to compensate for band fluctuations to absorb band fluctuations. Video distribution.

The operation of the above configuration will be described below. now,
The portable telephone 1 allows the user to transmit his / her own face and the like to the transmission path 23.
When transmitting video and audio to a terminal device such as the videophone 24 of the other party via the terminal, the lid unit 3 is rotated by 180 ° as shown in FIG. Can face the front side of the housing body 2 to image the display device 6 of the opening 3 of the imaging camera 11 of the housing body 2 and the lid unit 3 toward itself.
It is possible to easily take an image while watching and monitoring his / her own face on the screen 17.

In the state shown in FIG. 2A, the lid 3 is folded forward from the state shown in FIG. 1A, and the opening of the imaging camera 11 provided on the rear side is directed toward an external subject. In this case, it is possible to take an image while monitoring the screen 17 to be imaged by the display device 6. In this case, the jog dial 14 can be associated with the imaging means.

Further, as shown in FIG. 1 (C), even when the lid portion 3 is opened, an external subject can be imaged through the imaging camera 11 disposed on the back of the housing main body 2, and the display device can be displayed. 6 can be used as a monitor of a subject, but in this case, the monitor screen is used as a monitor screen at the time of various input data operations such as telephone conversation, image transmission, and e-mail of the portable telephone 1.

In the state shown in FIG. 2A, when the jog dial 14 is operated with one hand, the jog dial 14 is folded, so that the operation becomes easy. In this state, since the operation unit such as the numeric keypad 4 shown in FIG. 2C is hidden by the lid, it is suitable for selecting a predetermined address or a predetermined music in the above-described Internet mail or music distribution.

FIG. 5 shows a state in which the lid 3 is rotated by 180 ° as shown in FIG. 2A, and the operation is performed by operating the jog dial 14 in the miniaturized portable telephone 1 folded to the front side. 2 illustrates the relationship between the display screens 17 on the display device 6.

The operator's hand 2 shown in FIGS. 5A and 5B
8 shows a case where the jog dial 14 is rotated clockwise CW, for example, as shown in FIG. FIG. 5A shows a case in which predetermined selected songs (selection items 1) are sequentially displayed on the upper side of the display screen 17 from the left side of the display screen 17, and FIG. 2 shows a case where predetermined selected music pieces (selection item 1) are sequentially displayed substantially at the center of the display screen from the right side.

In FIG. 5C, the font of the selected music (selection item 1) is sequentially increased from the lower side of the display screen 17, and
The font becomes the largest font at the center of the display screen 17, and the selected music (selection item 1) becomes easy to read. 2) can be displayed in large numbers.

The jog dial 1 in the state shown in FIG.
Turn 4 to select a specific song from the list (selection item 1)
When the jog dial 14 is pressed as shown in FIG. 5 (E), the switching means 26 is turned on, for example, and the system control unit 22 displays on the display screen 17 on the display device 6. The menu corresponding to the first selected song appears.

According to the portable terminal device of the present invention, a compact and operable device can be obtained when a predetermined item is selected at the time of Internet mail or music distribution.
