Abstract

PURPOSE:To attain automatic dialing through the use of a card by providing a traffic storage area in addition to a call number storage area and recording an optional specific telephone number into the area. CONSTITUTION:A magnetic zone 2 formed on the face of a telephone card 1 is divided into a call traffic storage area 2a storing the number of data of talking enable call and a number storage area 2b storing a specific telephone number. In loading the card 1 to a card reader 5 of a telephone set, a logic control section 3 reads a telephone number written on the card 1. Then the read telephone number is sent to a line by using an automatic number sending section 7. When the talking is applied and a charging signal comes from the exchange, a charging signal detection section 9 detects it to write the number of traffic into the call traffic storage area 2a of the card by using a card write section 6.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in a telephone card system for making calls using magnetic cards instead of coins.

(Prior art) Current telephone card systems have been developed and used as an alternative to coin-operated public telephones, and a telephone card with callable data recorded on a magnetic card is inserted into a card-type telephone. When a call is completed, the number of calls is deducted from the number of available calls on the card, an update is recorded, and the card is returned.
For example, Japanese Patent Application Laid-open No. 107375/1983).

According to this system, there is no need to prepare small change unlike the coin insertion type, and there is no need to worry about the coins being stolen from the phone because there is no need to collect the inserted coins. However, telephone cards are nothing more than a substitute for coins for telephone use. (Problem to be solved by the invention) The present invention focuses on the fact that there is still some free space in the magnetic recording section of telephone cards, and stores a specific telephone number there. By building a system that records and auto-dials only those numbers, it is possible to make a telephone card not just a substitute for coins, but to add an auto-dial function to the card that can automatically call a specific phone number. purpose.

Means for Solving Problem C) In order to achieve this object, the telephone card of the present invention is provided with a number recording area for recording specific telephone number data in addition to the frequency recording area; The card-type telephone is provided with a number automatic withdrawal part which reads specific telephone number data recorded on a telephone card and sends a dialing signal according to the number data to a telephone circuit as long as there is remaining power in the card.

(Function) When the telephone card of the present invention is inserted into a telephone, the callable power data recorded on the card is read, and if there is any remaining power data, the specific telephone number recorded on the card is read and the number is sent from the automatic number sending section. The caller sends out a dialing signal in response to the call and performs auto-dial, and the other party responds to this and the call is made.

When the call ends, the power will be subtracted from the power on the card.
The results will be updated and recorded on the card and the card will be returned.

Even if the telephone card is inserted, if there is no remaining callable data, the card will be returned as is without auto-dialing.

(Example) Fig. 1 is a plan view of a telephone card embodying the present invention, Fig. 2 is a block diagram showing an embodiment of a card-type telephone of the present invention that uses the telephone card of Fig. FIG. 3 is an operational flowchart of the embodiment of the present invention.

1 is a telephone card, and a magnetic band 2 formed on its surface is divided into a frequency recording area 2a for recording data on the number of possible calls per call, and a number recording area 2b for recording a specific telephone number.

Reference numeral 3 denotes a logical control section of the telephone, which is comprised of a processor, memory, etc., and starts operating when the receiver is hung up from the hook switch (off-hook). Reference numerals 5 and 6 denote a card reading section and a card writing section such as a magnetic head for reading and writing data on the card l, each connected to the logic control section 3.

Reference numeral 7 denotes an automatic number sending unit, which receives the read phone number in the number recording area 2b from the control unit 3 if there is any remaining data in the number of callable data that has been read, and immediately sends a dial signal according to the number data. is sent to the communication circuit 8.

As a result, the other party responds and a call is made, and a billing signal arrives from the exchange machine of the office every time a unit call time determined by one call distance elapses. This is detected by the billing signal detection section 9,
The number of times is stored in the memory of the control unit 3.

When the call is over and the receiver is placed on the hook switch 4, the control section 3 subtracts the call frequency from the frequency data of the card 1 based on the billing signal and outputs the result to the card writing section 6. As a result, after the update is recorded in the frequency recording area 2a of the card 1, the card 1 is ejected and returned.

10 is a dial. 1 When using a conventional telephone card that does not have a number recording area 2b, if the card has remaining frequency data, the control section 3 sets the telephone circuit 8 to a state where dialing can be made, and the dialing operation is performed. The original dial signal is sent to the telephone call circuit 8. In this case as well, it goes without saying that after the call, the frequency data on the card is updated and recorded according to the frequency of the call.

If there is no remaining callable data on the telephone card, the card will be returned without being able to make calls, as before.

(Effects of the Invention) As described above, according to the telephone card of the present invention, a number recording area 2b is provided in addition to the conventional frequency recording area 2a, and any specific telephone number is recorded in this, so that the user can make a telephone call. This eliminates the hassle of remembering numbers and eliminates the risk of dialing the wrong number.

Further, according to the card-type telephone of the present invention, since it is equipped with the automatic number sending section 7, it is possible to perform automatic dialing to automatically call a specific telephone number recorded on the telephone card as long as there are remaining callable points, which is convenient. .

Therefore, by writing the store's phone number on the telephone card of the present invention and distributing it free of charge to customers, customers can definitely call the store even if they do not remember the store's phone number, and the phone bill will be borne by the store. Since it is easy to make a phone call, it is suitable as a sales promotion item.
