JPH0637697A - Portable telephone set - Google Patents

Abstract

PURPOSE:To cope with an incoming call earlier than the conventional one by providing a second display which is seen from outside even in a closing state other than a first display in front. CONSTITUTION:A portable telephone set 1 has folding construction in which first and second housings 1a and 1b can mutually be folded at a hinge part 2. The display 8 is mounted in front which has a speaker 15 and a lead switch 12 in a state there the housings 1a and 1b are mutually opened. Consequently, when the housings 1a and 1b are mutually folded with the hinge part 2 In a center, the display 8 can not be seen but only the display 11 can be seen. Besides, in the state of being folded, a magnet 13 is operated and as the result, a selection circuit 10 operates so as to send power and character data from a display driver 9 only to the display 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone, and more particularly to a mobile phone having a display and a folding structure.

[0002]

2. Description of the Related Art Conventionally, a mobile phone of this type has only one display, and this display is usually mounted at a position where it cannot be seen from the outside when the folding structure is closed. .

[0003]

Since this conventional mobile phone is mounted in a position where the display cannot be seen when the folding structure is closed, it is generally used in a folded state in waiting for an incoming call. If so, there is a problem that display contents such as electric field strength display, battery voltage display, and incoming call display cannot be confirmed.

[0004]

The mobile phone of the present invention comprises:
In a mobile phone having a folding structure in which a first casing having a speaker and a second casing having a microphone are mutually foldable at a hinge part, the first casing having a foldable structure that is invisible from the outside when the foldable structure is closed. 1 indicator and a second indicator in a position visible from the outside even when the folding structure is closed, and the first indicator with the folding structure opened and the second display with the folding structure closed Power supply switching means for supplying power to the second display is provided, and the second display is mounted on the same surface as the surface on which the antenna is mounted when the folding structure is closed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a schematic diagram showing an example of a usage state of this embodiment.

In FIG. 1, the mobile phone 1 of the present embodiment has a first housing 1a and a second housing 1b having a folding structure in which a hinge portion 2 can fold each other, and the first housing 1a Is a wireless unit 4 to which the antenna 3 is connected, a display 8 for displaying the state of communication and the mobile phone 1, a display 11 on the surface where the antenna 3 is located, and a display 8, 1.
1, a display driver 9 for supplying power and outputting character data, a selection circuit 10 for switching output of power and character data from the display driver 9 to the display 8 or 11, and a switching signal for the selection circuit 10. Reed switch 12 to send
And a speaker 5, and the second housing 1b has a control unit 5 for controlling the entire mobile phone 1, a battery 7 for supplying electric power to the whole, a key operation unit 6, and a magnet for turning on / off the reed switch 12. 13 and a microphone 14.

The display 8 is composed of the first and second casings 1a,
The speaker 1 and the reed switch 12 are attached to the front side with the speaker 1b open to each other.

The first casing 1a and the second casing 1b are
When the hinges 2 are folded around each other, the display 8 is no longer visible and only the display 11 is visible.

Further, in this folded state, the magnet 13 acts on the reed switch 12, and as a result, the selection circuit 10
Operates to send the power and character data from the display driver 9 only to the display 11. As a result, even in the folded state as shown in FIG. 2, it is possible to confirm the display of only important information such as the electric field strength and the battery voltage in the standby state of the incoming call by the display unit 11.

[0011]

As described above, according to the present invention, in addition to the first display device on the front surface, the second display device that is visible from the outside and the folding structure is provided so that the folding structure can be closed. Since the information that needs to be confirmed can be confirmed on the second display, there is an effect that it is possible to respond to incoming calls earlier than before.
