[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In FIG. 1, reference numeral 2 denotes a main body of a mobile phone compatible with the Internet, on which a cover 6 on which a vertically long display 4 composed of a liquid crystal display device or the like is fixed is pivotally supported to open and close. On the surface of the main body 4, soft keys, cursor keys, dial keys, and other keys necessary for basic mobile phone calls, Internet operations, and the like are arranged.

The cover body 6 is provided on a hinge member (not shown) rotatable with respect to a horizontal axis (not shown) provided at an upper portion of the main body 2. It is rotatably supported in forward and reverse directions within a range of 90 degrees in a parallel plane. The pivot portion of the cover body 6 can be easily released by external stress at a position of 0 degree in the vertical direction shown in FIG. 1A and a position rotated by 90 degrees in the horizontal direction shown in FIG. 1B. A lock mechanism (not shown) for fixing is provided.

As shown in FIG. 3, a CPU 12 is provided on a substrate inside the main body 2, and a memory 14 storing a telephone number and an Internet-compatible program is connected to the CPU 12. An antenna 16 provided on the main body 2 is connected to the CPU 12 via a radio wave transmission / reception control unit 18. The radio wave transmission / reception control unit 18 converts a signal from the antenna 16 into a digital signal, and converts the digital signal into various modulation schemes and transmits the signal from the antenna 16. Further, the radio wave transmission / reception control unit 18 performs a baseband (BB) signal processing operation of converting the converted digital signal into audio data, image data, and the like.

The key operation unit 8 is connected to the CPU 12 via a key input control unit 20. The receiver 22 and the transmitter 24 provided in the main body 2 are connected to the CPU 12 via a transmission / reception control unit 26. A display control unit 28 is connected to the transmission / reception control unit 26, and the display control unit 28 is connected to the vertically long display 4 via a vertical / horizontal display switching unit 30. As shown in FIG. 4, the vertical / horizontal display switching unit 30 includes a horizontal mode display drive circuit 32, a vertical mode display drive circuit 34, and a mode switching unit 36.

As shown in FIG. 5A, the horizontal mode display drive circuit 32 converts the input image signal 38 into an X coordinate axis on the display 4 using the 01 point set on the vertically long display 4 as a coordinate reference. 40, and are developed and displayed on the coordinate plane of the Y coordinate axis 42. On the other hand, as shown in FIG. 5B, the vertical mode display drive circuit 34 uses the input image signal 38 as a coordinate reference with the 02 point set on the vertically long display 4 as an X coordinate axis 44 on the display 4. , On the coordinate plane of the Y coordinate axis 46.

The mode switching section 36 constitutes a gate circuit that turns on one of the horizontal mode display drive circuit 32 and the vertical mode display drive circuit 34 and turns off the other. It is configured to be input. The key operation unit 8 is provided with a screen switching key (not shown) for inputting a switching signal to the mode switching unit 36 to the CPU 12. The mode switching section 36 is normally set to a normal display mode in which the horizontal mode display drive circuit 32 is turned on and the vertical mode display drive circuit 34 is turned off.

In the above-described configuration, when the user starts a voice call, the user inputs a telephone number with the dial key from the key operation unit 8 and notifies the CPU 12 of the telephone number, or the telephone number of the other party stored in the memory 14. The number is read out and transmitted to the CPU 12, and a call key in the key operation unit 8 is pressed to make a call. At this time, a call request signal is transmitted from the CPU 12 to the base station via the antenna 16 via the radio wave transmission / reception control unit 18. After each outgoing call sequence from the mobile phone is exchanged with the base station, a call is established. After being input from the transmitter 24, the voice call signal is converted into a digital signal by the transmission / reception controller 26.

Normally, as shown in FIG. 1A, a mobile phone is used with a display 4 in a vertically long state. An image signal input from the antenna 16 through the Internet is converted into a digital image signal by the radio wave transmission / reception control unit 18 and input to the CPU 12. In addition, an image signal is input to the CPU 12 from outside the Internet from the memory 14 or from an external storage medium (not shown) such as a memory chip mounted on the main body 2. The CPU 12 sends the digital image signal to the transmission / reception control unit 26. The image signal sent to the transmission / reception control unit 26 is sent to a display control unit 28, where it is processed into an image signal for driving the display 4, and then the mode switching unit 36 of the vertical / horizontal display switching unit 30. Is transferred to the horizontal mode display drive circuit 32, and the image signal 38 is displayed on the XY coordinate axes 40 and 42 of the display 4.

When the horizontal width of the image signal 38 is large and it is difficult to see the image signal 38 on the vertical display 4, a display mode switching signal is sent to the mode switching unit 36 to turn off the horizontal mode display drive circuit 32 and turn the vertical mode display drive circuit 34. Is turned on. Thus, the image signal 38 is displayed on the XY coordinate axes 44 and 46 on the basis of the 02 point on the display 4. At this time, the user rotates the cover body 6 90 degrees counterclockwise from the vertical state of FIG. 1A around the pivot 10 so that the image signal 38 can be seen in the correct direction. The display 4 is oriented horizontally.

In the above embodiment, the cover body 6 is configured to be rotatable within a range of 90 degrees with respect to the main body, but as shown in FIG. The frame 50 of the display is rotatably attached to the main body 52 within a range of 90 degrees around the pivot 54 to connect the frame 50 and the main body 52, and the display frame 50 is rotated as shown in FIG. 2 (B). Thus, the display 48 may be configured to be able to change its orientation from portrait to landscape or vice versa.

[0015]

[Effect of the invention]

 As described above, according to the present invention, a vertically long display can be used in either a portrait or landscape orientation, so that image data that is long in the horizontal direction can be displayed on the display in an easily viewable state.
