Thus, the convenience of use is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless telephone such as a cordless telephone or a cellular telephone.

[0002]

2. Description of the Related Art Conventionally, a cordless telephone, which is composed of a combination of a master unit and a slave unit and has a master unit connected to a telephone line so that the slave unit can talk in a place away from the master unit, has been widely used. Cellular phones, which are wirelessly connected to central offices, have come into use. In such a portable telephone, for example, as disclosed in Japanese Utility Model Laid-Open No. 1-65541, two cabinets are rotatably connected to each other so as to be foldable, and the cabinets face each other. There is one in which a numeric keypad or the like is arranged on the surface to be mounted, a speaker is arranged in one cabinet, and a microphone is arranged in the other cabinet to achieve miniaturization.

[0003]

However, in the above configuration, the call answering process is performed after the cabinet is opened even when there is an incoming call from the outside line in the closed state, that is, even when it is not necessary to operate the numeric keypad or the like. I had to do it.

[0004]

The mobile phone of the present invention comprises:
In a mobile phone in which a first cabinet and a second cabinet are rotatably coupled to each other, when the respective cabinets are closed, a call key provided in a portion of one cabinet not covered by the other cabinet and the respective cabinets are closed. Two microphones installed in one or the other cabinet to enable voice input when open and closed, and detecting whether each cabinet is closed or open And a selecting means for switching and selecting the respective microphones based on the detecting means.

[0005]

Since the present invention is configured as described above, for example, when an incoming call is received from an outside line, a call key is used to perform a response process, and then a call is made without closing each cabinet. can do.

[0006]

Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, (1) is a first cabinet that contains electronic components and the like, and (2) is a second cabinet that is rotatably attached to the first cabinet via a hinge portion (3).

The first cabinet (1) is provided with an earpiece (4), a call key (5), an off key (6), a dial key (7) and a power key (8), and a second cabinet (1). When 2) is closed, the dial key (7) and the power key (8) are covered by the second cabinet (2) as shown in FIG. Further, the first cabinet (1) is provided with a lock mechanism (not shown) so as to maintain the closed state and to release the lock with the release button (9). The call key (5) and the off key (6) are used for the second cabinet (2).
However, since it is provided in the recess (10), it is less likely to be erroneously operated when being carried.

By the way, although the second cabinet (2) is provided with a transmitter, in the present invention, the first transmitter corresponds to the open state and the closed state as shown in FIGS. A talker (11) and a second transmitter (12) are provided. Then, microphones (13) and (14) are provided as shown in FIG. 3 corresponding to the respective transmitters (11) and (12).
As shown in FIG. 4, the microphones (13) and (14) have ribs (1) on the lower plate (15) of the second cabinet (2).
6) It is fitted inside, and the upper plate (17) and the lower plate (1)
It is sandwiched by 5).

Thus, in the above structure, for example, when the respective cabinets (1) and (2) are closed and carried,
If there is an incoming call from an outside line, you can operate the call key (5) to answer the call without opening the cabinets (1) and (2) and operate the off key (6). You can end the call. When dialing, the cabinets (1) and (2) are opened, and then the call key (5) and the dial key (7) are operated, without closing the cabinets (1) and (2). You can talk in this state.

However, two microphones (13) (1
When 4) is activated, ambient noise is introduced from one of the microphones that is not required for the call (in the state of Fig. 1, noise from the back side of the telephone is also input), and the voice wraps around and voices of different levels are heard. Each microphone (13)
Since it is delayed to enter (14) and the other party is hard to hear, in the present invention, as shown in FIG. 1, the first cabinet (1) has a hole (15) and the second cabinet (2) has a protrusion ( 16) and when the cabinets (1) and (2) are closed, holes (15) are provided as shown in FIG.
The changeover switch (17) provided in the first cabinet (1) is operated by the projection (16) via the.

Thus, the changeover switch (17) is connected to the control circuit (18) built in the second cabinet (2), and the control circuit (18) responds to ON-OFF of the changeover switch (17). Either transistor (1
9) By turning on (20), the microphone (14) is made inoperative in the open state (FIG. 1), and the microphone (13) is made inoperative in the closed state (FIG. 2).

[0012]

Since the present invention is configured as described above, for example, when an incoming call is received from an outside line, a response process is performed using a call key, and then each cabinet is closed without being opened. It is possible to provide a mobile phone that is easy to use and can make a telephone call.
