Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a portable telephone and a PHS
In particular, the present invention relates to a mobile terminal capable of checking a display by separating a module having a display unit while continuing a conversation.

[0002]

2. Description of the Related Art Generally, when making a telephone call with a portable telephone or a PHS, almost all of the communication is carried out with the portable terminal itself being put to the ear at present. On the other hand, mobile terminals have been provided with communication functions such as not only communication of conversations but also storage and display of data such as telephone directories and e-mails. Under these circumstances, there is a demand for confirmation and transmission of stored data during a call. However, at present, due to the structure of mobile phones, a receiving speaker, a display unit, dial keys,
Since the microphones and other components are integrated and inseparable, for example, when communicating the contents of the telephone directory or e-mail stored on our side to the other party during a call, first stop the conversation first. Desired data is output to a display, the contents of which are memorized by the user, and then the call is resumed and transmitted to the other party. To solve the troublesome operation, for example, according to the disclosure of Japanese Utility Model Application Laid-Open No. 3-44349, an operation unit and a display unit can be separated from the telephone device main body to facilitate the operation and confirmation. Had been served.

[0003]

However, in the conventional method for temporarily stopping the conversation as described above, the number of digits of the current telephone number and the amount of e-mail data are large, so that the work is complicated and the transmission accuracy is low. Is low, it is not easy to confirm the contents of the display unit while continuing the conversation. In contrast, in the conventional technology that separates both the operation unit and the display unit from the main unit, which has been proposed to facilitate operation and confirmation, the operation unit is separated, so that the contents of the operation must be carried by wireless weak radio waves. It is necessary to communicate with the terminal body and operate the mobile terminal body.In addition to the transmission / reception circuit used for normal communication between the mobile terminal body and the base station, an operation unit and a display unit separated from the mobile terminal body are provided. Since the transmission / reception circuit for performing the data communication must be provided in both the operation unit and the display unit separated from the portable terminal main body, there is a problem that the amount of circuits increases.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problem, and does not increase the amount of circuit for communicating with the portable terminal main body by operating the module, and allows the portable terminal main body to communicate with the ear during a call. An object of the present invention is to provide an excellent portable terminal capable of performing a data confirmation operation while continuing a conversation without releasing the terminal.

In the portable terminal according to the present invention, the module includes a tone signal output switch. When the module is mounted on the portable terminal main body, the tone signal output switch controls the DTMF from the speaker of the portable terminal main body. An automatic dialer function for outputting a signal tone is provided. With this configuration, the mobile terminal body has an auto dialer function,
With the module installed, you can easily dial the other party from a wired line, so even when the mobile terminal is out of the area, the phonebook data in the module can be saved without removing the module from the mobile terminal. The user can easily call the other party.

In the portable terminal according to the present invention, the module includes a tone signal output switch. When the module is separated from the portable terminal body, the DTMF signal sound is output from a speaker of the module by controlling the tone signal output switch. Is provided with an auto dialer function for outputting With this configuration, when the module is used alone, not only the function of simply displaying the contents of telephone directory data and e-mail but also the telephone number displayed is converted into a DTMF signal, and the DTMF signal sound is transmitted to the module. It can be used as an auto dialer function that outputs from the equipped speaker and calls the other party from a wired line or the like.
