2. Description of the Related Art At present, digital communication is capable of performing not only voice but also data communication, facsimile communication or image communication at high speed and high quality. Therefore, digital mobile communication has been developed in Western countries. But the digital communication network has started to be established. A mobile phone is one of the tools for this digital mobile communication.

[0003]

However, the conventional digital mobile phone has only a real-time transmission / reception function. Therefore, where there are computers and fax machines,
Data transmission / reception or facsimile transmission / reception can be performed only when connected to these digital input / output devices through an interface, and data transmission / reception or FAX transmission / reception cannot be performed at a place where a computer or FAX is not available.

Therefore, an object of the present invention is to provide a digital voice signal, a data signal, and a fax even in a place without an input / output device.
To obtain a digital mobile phone that can send and receive signals and image signals.

[0005]

In order to achieve this object, the digital mobile phone of the present invention can be built in the housing, receives the input from the digital receiving means and the analog-digital converting means, and also performs the digital transmission. Means and a buffer memory means for outputting to the digital-analog conversion means, and a control means for controlling the buffer memory means and the other means, by which the digital signal is not diverted to the buffer memory means. It is characterized in that it is possible to switch between a normal buffer invalid mode and a buffer valid mode for bypassing the buffer memory means and accumulating or selectively outputting a digital signal in the buffer memory means.

[0006]

In the digital portable telephone according to the present invention, the buffer memory means is switched from the normal buffer invalid mode to the buffer valid mode by the control means when the call cannot be answered even if there is a call to be spoken. , The voice message of the other party (digital voice signal) is temporarily stored in the buffer memory means, and when the telephone response becomes possible, the voice message stored in the buffer memory means is output from the voice output means via the control means. By listening to it, I call the other party again to make contact. It can also function as a voice memo for temporarily recording one's own voice in the buffer memory means.

Further, when there is no input / output device such as a computer or FAX at the destination, for example, when there is a call to receive data or FAX, the control means sets the buffer memory means to the normal buffer invalid mode. Switching to the buffer valid mode, the transmitted digital signal such as a data signal or a FAX signal is stored in the buffer memory means. After this, when the personal computer returns to an office or arrives at a place with a fax facility such as a hotel, the digital information signal accumulated from the buffer memory means is wirelessly transmitted or wired (via the interface means).
Outputs to computer or FAX by transmission.

Furthermore, after the still image taken by the digital still camera is transferred to the built-in buffer memory means, the digital camera can be disconnected, and the digital camera is ready to take a picture and stored in the buffer memory means. It is also possible to transfer the static image information thus made to a remote receiver (for example, a personal computer) via the digital telephone line network at an arbitrary time.
