DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone, and more particularly to a portable telephone comprising a master unit and a slave unit.

[0002]

2. Description of the Related Art A conventional portable telephone has a display unit in one housing,
A key input unit, microphone, speaker, etc. are mounted. In addition, the size of the mobile phone itself has been reduced. Further, in recent years, not only voice information but also text information can be communicated with a mobile phone.

[Problems to be solved by the invention]

[0003] Even if the size of the mobile phone is further reduced, it is considered that it is technically possible by integrating electronic components. However, the mobile phone is used by human beings in the first place. Usability is getting worse. For example, many mobile phones that fit easily in a clothes pocket have difficulty in operability. Although there may be some products that are easy to use even if they are small, there is still a limit to the size of the mobile phone itself.
That is, there is a limit to size reduction (especially length) in consideration of ergonomic operability and the like.

[0004] For this reason, there are many portable telephones which cannot be stored in pockets of clothes, and are often carried in bags or the like. However, there is a problem that if a mobile phone is put in a bag, it is difficult to understand the notification operation such as a ring tone or vibration at the time of an incoming call. For example, if the volume is set to be large so that the ringing tone can be heard, the volume suddenly becomes high when taken out of the bag, which may disturb the surroundings.

[0005] In addition, when the user notices the incoming call notification and tries to remove the mobile phone from his bag, the telephone is often disconnected.

[0006] For this reason, people who wear a mobile phone around their neck have come to be seen. However, the size of the mobile phone is not so good and it is hard to look like in a new scene. See FIG. 6).

On the other hand, with respect to character information communication (for example, e-mail) by a portable telephone, there are many models in which reception of character information can be completed without connecting a line as in normal voice reception, as in normal voice reception. Therefore, the notification operation time is often short. For this reason, there is a case where the user does not notice the arrival of the character information and sometimes loses a serious opportunity.

However, character information (for example, electronic mail)
Basically, it is implicit common sense not to seek immediacy, but work-related information is something that we want to check in real time.

A first object of the present invention is to provide a portable telephone which is small in size, has good operability, can make a call immediately, and does not bother the appearance.

A second object of the present invention is to provide a portable telephone capable of confirming character information in real time.

[0011]

According to an aspect of the present invention, there is provided a portable telephone having an operation surface and capable of communicating with a base station, and a transmitting means for transmitting a signal in conjunction with incoming and outgoing reception. And a notifying unit that separates the master unit from the master unit and notifies an incoming call by detecting a signal transmitted from the master unit, and receives a signal transmitted from the master unit by detecting the signal transmitted from the master unit. And a display unit for displaying character information, wherein the master unit is mechanically detachable from the slave unit, and the slave unit is mounted in the machine when the slave unit is worn. It is characterized by being housed and integrated.

In the portable telephone, the master unit has no display means when it is separated from the slave unit, and the display means of the slave unit is integrated with the master unit. In the above, it is preferable to be arranged on the operation surface side of the master unit.

Further, in the portable telephone, the master unit has a connection terminal for transmitting a signal in a wired manner in conjunction with incoming and outgoing reception on a surface in contact with the slave unit, and the slave unit is connected to the master unit. A contact surface is provided at a position corresponding to the connection terminal of the master unit, the connection terminal being electrically connected to the connection terminal of the master unit, and detecting a signal transmitted from the master unit. Is preferred.

Further, in the portable telephone, the master unit has an entrance at a side end surface for accommodating the slave unit, and a slide for slidingly housing the slave unit inside the entrance. Preferably, the slave unit has a sliding surface on a surface corresponding to the sliding surface of the master unit.

Further, in the portable telephone, it is preferable that the slave unit has a key input unit.

Also, in the portable telephone, the slave unit includes a microphone, a speaker, and communication means for transmitting and receiving call information, respectively, and the master unit works in conjunction with the communication means of the slave unit. It is preferable to include communication means for transmitting and receiving call information by using the communication means.

In the portable telephone, the slave unit has a strap for hanging from the neck of the person, and the strap is attached to both shoulders of the person when the slave unit is hung from the neck of the person. Preferably, the speaker is provided at a position, and the wiring of the speaker is laid in the strap and electrically connected to the main unit.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION Portability and immediate correspondence of information are improved by extracting some functions such as a display portion from a mobile phone main body and separating them into a small and lightweight slave unit. In addition, by assigning a call function to the child device, it is possible to immediately respond to an incoming call.
