Next, the operation of the present invention will be described with reference to the flow chart 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 to set the off-hook state, the call is started in step 2 by the dial operation performed subsequently.
At this time, the switch means 111 is set to the receiving speaker 102 side and the echo canceller 115 is set to the non-operating state under the control of the system control unit 125, and the user puts the receiving speaker 102 on his / her ear and transmits. Use microphone 103 for transmission. When it becomes 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 make a memo by handwriting. Like That is, when the operation of the memo mode key 134 is detected in Step 3, the system control unit 125 and the display control circuit 123 set the memo mode as shown in Step 4, and then in Step 5, the system control unit 125 operates. By control, the switch means 111 is switched to the hands-free reception speaker 113 side, the echo canceller 115 is set to the operating state, and the hands-free call state is set. Therefore, it is possible to write down the necessary information without interrupting the call.

On the other hand, when the user wants to have a conversation while looking at the FAX image already transmitted from the other party during the call and stored in the page memory 120 after reception after the start of the call in step 2, the FAX mode key 135 is operated. The received FA is set to the FAX mode shown in FIG.
You can talk while watching the X image data. That is, when an instruction to set the FAX mode is detected in Step 6, the FAX mode is switched to the FAX image data received in Step 7, and the switch means 111 is controlled by the system control unit 125 in Step 5. Switching to the handsfree speaker 113 side, the echo canceller 115 is set to the operating state, and the handsfree call state is set. Therefore, the call can be continued while watching the received FAX image.

In either case, when the call ends and the on-hook state is established, the switch means 111 causes the receiving speaker 1 to operate.
02 and the echo canceller 115
Is set to the inactive state.

When setting the hands-free call state, it is preferable to increase the gain of the amplifier of the transmitting microphone 103 (not shown). Further, in the present embodiment, the hands-free call mode is set by operating the memo mode key 134 and the FAX mode key 135, but 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 includes the input display device and
A hands-free listening speaker, an amplifier that amplifies the received voice signal and drives the hands-free listening speaker, and selects the received voice signal as one of the listening speaker and the hands-free listening speaker. Output means, an echo canceller for preventing howling during a call, and a hands-free operation by controlling the switch means and the echo canceller based on detection of a predetermined input to the input display means during a call. Since a control means for switching to a call is provided, for example, even if the user removes the mobile phone device from the ear when making a memo on the input display device during a call, the call is automatically set to hands-free call, so the conversation is interrupted. You can take notes without

Also, during a call, even if a FAX image already received from the other party of the call is displayed and a conversation is made while watching this, the conversation is not interrupted.
