TECHNICAL FIELD The present invention relates to a transmission system using a telephone line,
In particular, send a card such as
You can insert a receiver to send messages.
The present invention relates to a transmission system using a speech line. Conventional technology Conventionally, a message was recorded on a card and the card was
You can send message contents by connecting to a transceiver such as a telephone.
There was no transmission system that could do this. Similar to this
There is an answering machine, but this is, for example,
Record a message on your recording tape that you are out
When a call comes in, within a prerecorded message
Tell the other person, record the message from the other person
It is possible that there is a transmission from the other party.
It works when you play. Also, it is transmitted to a conventional recorder.
Record your words, pick up the phone's transceiver,
The recorder can be played back and the recorded content can be transmitted.
However, in this case, the electric signal from the recorder is sent directly to the telephone.
It does not convey. Problems to be solved by the invention When you want to send a message to your home or friend's house by telephone, the public telephone is empty.
If you are not there
Sometimes it is impossible to convey a word. Also, only the message
It's best if you can, and sometimes you don't want to talk to the other person directly.
In this way, anyone can feel the inconvenience and dissatisfaction with the telephone many times.
I'm trying, for example, if the other person is absent
I want a system that can automatically send messages to the other party later.
It is rare. The purpose of this invention is therefore to convey the message.
Even if the person you want to attend is absent, a message is automatically sent to the person.
You can send it and leave it
A transmission / reception system using a telephone line that can receive words arbitrarily
It is to provide. Means for Solving the Problems This invention is for transmitting and receiving telephone calls using telephone lines.

Performs collation with the PIN entered in the figure pre-entry
(Step S52). This verification is a pre-entered PIN
And the personal identification number recorded on the magnetic stripe 17
You may do it again. If they do not match, the transaction cannot be displayed
(Step S57), eject the IC card (step S57)
60) ends the operation, but if they match, step S53
Go to and display the amount of withdrawal on the display of the automated teller machine.
do. The customer confirms the withdrawal amount, and when making a transaction, the current
Press the confirmation key on the keyboard of the automated teller machine.
Step S54). The customer is changing the withdrawal amount or processing the transaction
To stop, press the cancel key (step S58).
If you press the confirmation key, the withdrawal slip together with the money
Eject (step S55), then into the IC card memory
The transaction is recorded (step S56). Continued
Erase the data previously entered in the IC card (step
(S59), eject the IC card (step S60), and
finish. Cancel key after the amount is displayed in step S53
If is pressed, from step S59 described above.
Later actions are taken. Moreover, as described in FIG. 2, the IC card 1 is a calculator.
It has a function, so if you do daily shopping and household budget calculations
You can use this card as well. As described above, according to the present invention, the first memory hand of the card is
Information indicating the telephone number of the other party and a digital voice signal,
That is, if the information indicating the message is stored, the card
Connect to the transmitter / receiver to write to the desired destination.
The stored message is transmitted through the line and the transceiver.
Therefore, even if the other party is absent, it will be automatically transmitted to the other party.
You can leave a word. Also, in the first storage means of the card
If the information indicating the telephone number of the recipient is stored, the car
Connected to the transceiver, the
Information indicating the message that was sent, that is, the message sent from the other party during absence.
Information indicating the message that is received and remains in the second storage means
It can be received as an arbitrary voice. Therefore,
By using the card, the person you want to send the message to is absent
Even if, etc., automatically send a message to the other party and leave it
And the other party can voluntarily record the remaining message
To obtain a transmission / reception system using a telephone line
be able to. In addition, even if the other party is absent
Since it is possible to avoid repeating the work, congestion on the telephone line
Is reduced.
