Further, the control unit 7 transmits notification information to the other party when the call is received in the simple answering machine mode to notify the other party that the simple answering machine mode is set, and a call receiving the message information from the notifying unit. A detecting means for detecting a telephone number and message information from the user side is realized, and the memory 14 stores the telephone number and message information detected by the detecting means and the detection time.

Next, the main part of the receiving operation of the telephone device will be described with reference to the flowchart of FIG. When the simple answering machine key is turned on by the user and an incoming message is received during standby (step S1), it is determined whether or not a simple answering machine mode is set (step S1).
2). In this case, since the simple answering machine mode is set, a ringing tone is not emitted and a signal or a keypad facility message is transferred to notify the other party of the simple answering machine mode (step S3).
A timer for measuring a predetermined time is started (step S4). The signal and the keypad facility conform to RCR STD-27A. The signal is a signal for transmitting information for the network to generate a tone or a call signal to the terminal, and has a structure as shown in FIG. 5 and a content as shown in FIG. The keypad facility is used to carry the IA5 character set by the terminal keypad, or used by the user to request the network to transmit a PB signal, and has a structure as shown in FIG. The contents are as shown in FIG. Next, it is determined whether the message or the telephone number of the caller of the other party has been received (step S5), and if received, it is stored in the memory 14 (step S6). Further, the memory 14 is searched to determine whether there is a telephone number that matches the telephone number of the caller, and if so, the name of the other party is stored in the memory 14 in association with the telephone number. Next, a confirmation message is transferred (step S7), a disconnection message is transmitted and received (step S8), and a disconnection state is entered. Next, it is determined whether there is a message stored in the memory 14 (step S).
9) If there is, the LED is blinked, the number of messages is displayed on the LCD (step S10), and the process returns to the standby state. If it is determined in step S9 that there is no message stored in the memory 13, the process returns to the standby state. If it is determined in step S5 that the message or the telephone number of the caller of the other party has not been received, it is determined whether or not the timer has timed out (step S5).
11) If it has timed out, proceed to step S8,
If not, the process returns to step S5. If it is determined in step S2 that the mode is not the simple answering machine mode, the process proceeds to a normal incoming call operation, sounds a ringing tone, enters a communication channel, and the user speaks (step S12).

Next, the main part of the calling operation of the telephone device will be described with reference to the flowchart of FIG. First, a call is transmitted (step S21), and it is monitored whether a message in the simple answering machine mode is received or a call confirmation message is received (step S22). When the simple answering machine mode message is received, the simple answering machine mode is displayed on the LCD (step S23), and the user is notified. When the user inputs a message by key input (step S24), the input message is transferred together with the telephone number (step S25), and a timer for a predetermined time is started (step S26). Next, it is determined whether or not a confirmation message has been received (step S27). If the confirmation message has been received, a disconnection message is transmitted and received, the disconnection operation starts (step S28), and the process returns to the standby state. If it is determined in step S27 that the confirmation message has not been received, it is determined whether or not the timer has timed out (step S29). If it has timed out, the process proceeds to step S28. If it has not timed out, the process proceeds to step S27. Return to Step S
If a call confirmation message is received at 22, a normal outgoing call operation is started and a transition is made to a call channel (step S30).

An outline of the above operation is shown in FIG. The called user can know that the message has been received by blinking the LED, and can know the number of messages by displaying the LCD. Therefore, the contents of the memory 14 are displayed in order from the upper
To be displayed. At this time, since an end code is written between the time and the telephone number and between the telephone number and the message at the time of storage, it can be recognized by reading the end code.

As described above, when the call is received in the simple answering machine mode, the message information is transferred to the caller side to notify that the simple answering machine mode is set, and the message information from the notifying means is transmitted. Detecting means for detecting the received telephone number and message information from the caller side is realized by the control unit 7, and the telephone number and message information detected by the detecting means are stored in the memory 14, and stored in the memory 14. Since the displayed phone number and message information are displayed on the LCD, it is possible to answer even if you want to answer the phone, for example, when boarding an airplane or train, driving a car, or at a concert hall. If you are unable to do so, you can automatically record the phone number or message of the person you called, so that you can check its contents later. From, it is very convenient because it is possible to know at any time the opponent and requirements that have a phone call. Moreover, since the above-described processing is performed without entering the communication channel, it is possible to effectively use radio waves without using the frequency for the communication channel.

[0012] Further, if the configuration is such that the name of the other party is retrieved from the telephone number and stored as in this embodiment, it is very convenient because it is not necessary to remember the telephone number of the other party.
Also, as in the present embodiment, storing and displaying the arrival time together with the telephone number and the message is very convenient because it is possible to know when the call arrived. In addition, by using the contents stored in the memory 14, it is easy to automatically send a call to the other party later.

In the above embodiment, the contents of the memory 14 are set to L
