When the receiver picks up the handset 8 due to the ringing sound, the hook switch 11 is turned on, and the control means 13 detects this. Next, the control means 13 controls the interface circuit 5 to close the telephone line 1. As a result, the calling side and the receiving side can talk, and the audio signal input from the telephone line 1 is output from the receiver of the handset 8 via the interface circuit 5 and the receiving circuit 7, and the audio signal input from the microphone is output from the receiver of the handset 8. are the transmitting circuit 6 and the interface circuit 5.
The signal is output to telephone line 1 via . When the call ends and the user goes on-hook, the hook switch 11 is turned off and the control means 13 controls the interface circuit 5.

Open telephone line 1.

The calling party's telephone number is stored in the storage means 9 in the order in which the call was received, regardless of whether the receiver goes off-hook or not.

Therefore, if a call is received while the recipient is away, all the phone numbers received during that time are memorized, and when the user presses the display switch 12 after returning home, the phone number received while the recipient is away will be displayed. be done.

(Problems to be Solved by the Invention) However, the above configuration has the disadvantage that it is only possible to display the caller's telephone number, but it is not possible to leave a simple message. Note that answering machines have traditionally been used to leave messages, but they cannot record messages unless the telephone line is closed, so even leaving a simple message requires a call fee. There are some issues that must be addressed.

An object of the present invention is to eliminate the above-mentioned conventional problems and provide a telephone that does not require call charges just for message recording.

(Means for Solving the Problems) The present invention has achieved the above object by providing a ring signal detecting means for counting the number of rings or measuring the ringing time of a ring signal input through a telephone line, and a ring signal detecting means that stores a plurality of messages in advance. and a caller's telephone number detection means, the message storage means is configured to read a message from the message storage means in correspondence with the number of ringings or the ringing time of the ring signal detected by the ring signal detection means. This is achieved by a telephone configured to select and display the caller's telephone number on a display means together with the telephone number of the caller detected by the telephone number detection circuit.

(Function) According to the present invention, it is possible to display the caller's telephone number and message without the need to close the telephone line with the above configuration. Messages received from telephones that are not connected to the telephone line can be displayed without incurring call charges.

(Example) Hereinafter, examples of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a telephone in one embodiment of the present invention. Figure 2 is a flowchart showing the operation, Figure 3 is a flowchart showing the operation.
This figure is a waveform diagram of a ring signal, and FIG. 4 is a diagram showing a telephone number displayed on a display circuit.

In FIG. 1, 14 is ring signal end detection means, 15
is a ring signal counting means for detecting the number of ringings or the duration of the bell sounding, and the explanation of other symbols refers to the explanation of FIG. 5.

The operation of the telephone configured as described above will be described below.

First, the ring signal end detection means 14 will be explained.

As shown in Figure 3, the ring signal from the telephone line is 12O
The alternating current signal at about V continues for a first fixed time (° C. 1), and then the alternating current signal appears again after a second fixed time (t2). The ring signal detection means 14 detects the rise of this AC signal, sets a time t3 that is sufficiently longer than tl+t2, and counts the time from the rise of the ring signal. Mote t
When the rising edge of the ring signal is input again within 3 seconds, t
Set 3 and count the time. If the user does not go off-hook, the calling party goes off-hook, and no ring signal is input while counting t3, the ring signal end detection means 14 outputs a signal indicating the end of the ring signal to the control means 13. .

In addition, the storage means 9 has a plurality of information stored in advance, such as "Please call me."

Jr. I'll call you later. Messages such as J are stored in the form of digital data, and one of these messages is selected depending on the number of inputs of the ring signal. In this embodiment, assuming that the messages of the above two examples are stored in advance, if the ring signal is input 6 to 8 times,
If ``Call me please'' (hereinafter referred to as message 1) is input nine times or more, ``I'll call you later'' (hereinafter referred to as message 2) is selected.

With the above configuration, when the calling party's telephone number data is input along with the ring signal from the telephone line 1 (Step (hereinafter abbreviated as S) 1 in Fig. 2), a ringing sound is generated as in the conventional example. (S2), this telephone number data is stored in the storage means 9, and the ring signal counting means 15 counts the number of ring signals input based on the signal output from the ring signal detection circuit 2 (S3). Next, when the ring signal end detection means 14 detects the end of the ring signal (S4),
The value of the ring signal counting means 15 is detected by the control means 3 (S5), and if the count value is 6 to 8 times (S5)
5) Message 1 is selected (S6), and the message 1 is added to the telephone number previously stored in the storage means 9 and stored (S7).
