Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable communication device represented by a mobile phone.

[0002]

2. Description of the Related Art A conventional portable communication device of this type will be described with reference to FIGS. FIG. 4 is a perspective view showing the structure of a two-fold type mobile phone. In the figure, 1a is a receiver side casing, 1b is a microphone side casing, 2 is a hinge portion, and when carrying, it is folded by the hinge portion 2. The total length of the device can be reduced to about half. Reference numeral 3 is a receiver, 4 is a microphone, 5 is an operation button such as a dial, and 6 is an antenna.

FIG. 5 is a perspective view showing the structure of an integral type mobile phone having no folding mechanism. In the figure, the same reference numerals as those in FIG. 4 designate the same or corresponding parts, and 1c designates an integral housing. .

Since it is necessary to place the receiver 3 on the ear and bring the microphone 4 close to the mouth during a call, the distance and angle between the receiver 3 and the microphone 4 are determined in order to make a good call. The two-fold mobile phone shown in FIG. 4 is opened as shown in the same figure, the receiver 3 is put on the ear, and the user holds the two-folded case with one hand so that the microphone 4 is close to the mouth and talks. Also, when carrying, the receiver-side casing 1a and the microphone-side casing 1b with the hinge portion 2 as an axis
The length is shortened by folding so that they face each other, and they are stored in a pocket or the like. In such a two-fold mobile phone, the opening and closing of the case is linked with the on / off operation of the hook operation, and the line is automatically connected and ready to make a call just by opening the case. It is common to have a structure in which a telephone call can be made only by operating the, and the line is automatically cut off when the housing is closed.

Further, the mobile phone shown in FIG. 5 can make a call only by operating the hook button without requiring the opening / closing operation of the housing, but it cannot be miniaturized while being carried.

[0006]

Since the conventional portable communication device is constructed as described above, it has the following problems. That is, in the portable communication device shown in FIG. 4, when the housing is closed, all of the receiver, the microphone, and the operation button are hidden inside, so that the call cannot be made at all. Therefore, for example, when an incoming call is received while driving, the operation cannot be performed immediately, so that a quick and outgoing call operation cannot be performed. In addition, it becomes unstable because it is necessary to support the folded case with one hand while talking. Further, in the portable communication device shown in FIG. 5, since the microphone and the receiver are provided on one plane, the microphone is slightly separated from the mouth during a call with the receiver placed on the ear, and the call quality deteriorates. Further, if a miniaturization is attempted, howling is likely to occur because the microphone and the receiver come close to each other, which makes it difficult to miniaturize and has poor portability.

The present invention has been made in order to solve the above problems, and it is possible to carry out a call transmission / reception operation promptly even in a state of being carried, if necessary, without deteriorating portability and call quality. The purpose is to get the device.
