2 and ten keys 143 are displayed.

Next, the operation of the present invention will be described with reference to the flowchart shown in FIG. First, in the telephone mode shown in FIG. 3, when it is determined in step 1 that the call key 128 has been operated and the telephone has been set to the off-hook state, a telephone call is started in step 2 by a subsequent dial operation.
At this time, under the control of the system control unit 125, the switch unit 111 is set to the receiving speaker 102 side, the echo canceller 115 is set to a non-operating state, and the user puts the receiving speaker 102 on the ear and The call is transmitted using the microphone 103. When it is necessary to make a memo during such a call, the user operates the memo mode key 134 to set the memo mode shown in FIG. 4 and can make a memo by handwriting. Become like That is, when the operation of the memo mode key 134 is detected in step 3, the memo mode is set by the system control unit 125 and the display control circuit 123 as shown in step 4, and then in step 5, the system control unit 125 By the control, the switch unit 111 is switched to the hands-free speaker 113 side, the echo canceller 115 is set to the operating state, and the hands-free talking state is set. Therefore, necessary information can be recorded without interrupting the call.

On the other hand, if it is desired to have a conversation while viewing the FAX image transmitted from the other party during the call after the start of the call in step 2 and stored in the page memory 120 after reception, the FAX mode key 135 is operated. As a result, the fax mode is set to the fax mode shown in FIG.
A call can be made while viewing the X image data. That is, when an instruction to set the FAX mode is detected in step 6, the mode is switched to the FAX mode, the FAX image data received in step 7 is displayed, and the switch unit 111 is controlled by the system control unit 125 in step 5. Switching to the hands-free speaker 113 side, the echo canceller 115 is set to the operating state, and the hands-free talking state is set. Therefore, the call can be continued while viewing the received fax image.

In any case, when the call ends and the telephone goes into the on-hook state, the switch means 111 sets the receiving speaker 1
02 and the echo canceller 115
Is set to the non-operation state.

It is preferable to increase the gain of the amplifier of the transmitting microphone 103 (not shown) when setting the hands-free communication state. In this embodiment, the memo mode key 134 and the FAX mode key 135 are operated to set the hands-free call mode. However, an operation button for setting the hands-free call mode may be provided separately.

[0027]

As is apparent from the above description, the portable telephone device according to the present invention has an input display device,
A hands-free speaker, an amplifier that amplifies a received voice signal and drives the hands-free speaker, and selects a received voice signal as one of the receiver speaker and the hands-free speaker. Switch means for automatically outputting a signal, an echo canceller for preventing howling during a call, and controlling the switch means and the echo canceller based on detection of a predetermined input to the input display means during a call to hands-free. Since a control means for switching to a call is provided, for example, when taking notes on the input display device during a call, even if the mobile phone device is removed from the ear, the call is automatically set to a hands-free call, so the conversation is interrupted. You can make notes without having to.

Further, even if a FAX image already received from the other party is displayed during a call, and a conversation is performed while watching the FAX image, the conversation is not interrupted.
