In particular, a head card capable of reading a magnetic code signal of a credit card and a memory unit having a built-in program capable of controlling the credit card are provided to execute a credit card inquiry function. The present invention relates to a key phone system having a credit card inquiry function that significantly improves the versatility of the keep phone since the card inquiry function is additionally provided including the call function of the keep phone.

In general, as the industrial society develops, information communication systems are widely used to transfer data from one point to another desired more appropriately and quickly. Such communication systems are usually homogeneous or heterogeneous communication devices which are geographically dispersed. In most cases, information devices are connected to a network to enable sharing and communication of resources. In the network, a switch is usually used to exchange information converted into an electrical signal with a counterpart, and is divided into a subscriber transmission connecting a subscriber and an exchange and a transmission between stations connecting an exchange period.

In particular, various types of systems are currently developed and used in the exchange system for subscriber transmission in terms of large facility capacity, and a simple exchange system for a building or a small subscriber among such exchanges is now widely used. In addition, such a conventional simple exchange system, for example, a keep-phone, a board having necessary functions is inserted into a mother board, and each of these motherboards is combined according to a subscriber or other capacity. It is also possible to construct a rack.

Then, referring to FIG. 1, an example of the conventional keep-phone system as described above, a predetermined number of universal slots 71 into which external CO lines or extension cards 70A-N can be inserted, and this universal slot The backplane interface line 72 which is connected to each of the CO line or the extension card 70A-N inserted in the 71 and is a passage through which the signal to be switched is moved, and the backplane interface line 72 is connected. The function of the keep phone 75 including a switching function of the transformer 74 for separating the signal switched through the module jack 73 and the trunk lines or the extension cards 70A-N inserted into the universal slot 71. It consists of a main processor 76 that can control the overall.

One end of the main processor 76 is connected to a key panel unit 77 capable of inputting a user's control signal and an LCD panel 78 displaying an operation state therein. The other end of the ring detect unit 79 and the handset 80 for detecting a ring signal input through the backplane interface line 72 is connected.

On the other hand, looking at the operation of the conventional keep-phone system as described above, when a call signal is input from the external switch 81, the call signal is corresponding to the universal slot 71 of the keep phone 75 through the backplane interface line 72 It is input to the CO line card 70A and simultaneously with the ring detecting unit 79. At this time, the ring detecting unit 79 detects a ring signal carried in the input external call signal and rings a bell (not shown). Then, when the operator hears the ring tone and picks up the handset 80, the trunk line card 70A processes the voice signal of the other party's caller and sends it to the handset 80. Therefore, the operator confirms the extension number of the desired receiver from the other party's caller, and then presses the extension number through the key panel unit 77, and the main processor 76 recognizes this and allocates a channel to the corresponding extension card 70N. give. Then, a call connection signal is input from the trunk line card 70A of the universal slot 71 to the corresponding station card 70N. Accordingly, the call connection signal, for example, a voice traffic signal, is transmitted through a backplane interface line 72. The signal is matched via 74). Then, the call connection signal signal-matched by the transformer 74 is input to the wired telephone 82 via the module jack 73 to make a call between an external caller and an extension user. At this time, the main processor 76 displays the call state on the LCD panel 78 in letters or numbers through a display control signal.

However, since the conventional keep phone system as described above is operated only by a function of switching a call signal input from an exchange, a specific function, for example, cannot execute a function such as a credit card inquiry function. There was a significant disadvantage compared to the system.

In addition, the conventional keep-phone as described above has a drawback that the card look-up operation becomes very cumbersome and complicated, since a separate complicated card look-up has to be allocated to the extension of the keep phone 75 for the card look-up function.

The present invention has been invented to solve the above problems, and includes a head means capable of reading the magnetic code signal of the credit card and a memory unit having a built-in program to control the credit card inquiry function. Therefore, the purpose of the present invention is to provide a key phone system having a credit card inquiry function that significantly improves the versatility of the keep phone, since it has an additional card inquiry function including a call function of the keep phone.

Another object of the present invention is to provide a key phone system having a credit card inquiry function that can be performed by integrating a separate complex card inquiry into the keep phone in a simple circuit configuration so that ease of use is also significantly improved.

The present invention for achieving the above object is to execute a credit card inquiry function through a certain number of universal slots to insert a CO line card connected to an external credit card server, and the CO line card inserted into the universal slot A credit card inquiry function including a main processor, a head section for reading a magnetic code signal of a credit card in accordance with a card inquiry control signal of the main processor, and a printer section for outputting an inquiry result of a credit card read through the head section.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

The device according to the present invention has a predetermined number of universal slots 2 into which external CO lines or extension cards 1A-N can be inserted, and a CO line or extension card inserted into the universal slot 2. The overall function of the keep phone 3 can be controlled, including the switching functions of the 1A-Ns and the credit card inquiry function, and the credit is controlled according to the main processor 4 and the card inquiry control signals of the main processor 4. A head unit 5 for reading the magnetic code signal of the card, a memory unit 6 storing a program related to the card inquiry function of the main processor 4, and a credit card read through the head unit 5 The printer unit 7 outputs an inquiry result and a buzzer unit 8 which alarms an error of a credit card to the outside according to the error control signal of the main processor 4.

The backphone interface line 9 includes a backplane interface line 9 which is connected to each of the CO lines or the extension cards 1A-N inserted in the universal slot 2 and is a passage through which the signal to be switched is moved. A transformer 11 for separating a signal switched through the backplane interface line 9 from the module jack 10 and a control signal of a user connected to one end of the main processor 4, for example, a call function and a credit card. A key panel unit 12 capable of inputting a password, an LCD panel 13 displaying an internal operation state according to a display control signal of the main processor 4, and an input through the backplane interface line 9 And a ring detect unit 14 for detecting a ring signal to be generated.

In addition, a handset 15 is connected to one end of the main processor 4.

Next, the operation and effects of the present invention as described above will be described.

In the device of the present invention, when the keep phone 3 is set up and the main processor 4 is normally operated, the main processor 4 moves from the initial state S1 to the card inquiry mode determination step S2 as shown in FIG. It proceeds to determine whether the card lookup mode is currently set in the keep phone 3 system. At this time, if the card inquiry mode determination step (S2) is determined as a result, if the card inquiry mode is not set and the normal call mode is set to proceed to the general call processing function execution step (S3) to execute the general call processing function.

That is, when the keep phone 3 is set up, the main processor 4 determines whether a setting signal for card inquiry is input from the key panel unit 12 in the standby mode. The main processor 4 switches to a normal call mode and executes a general call processing function when a setting signal for requesting a card inquiry is not input from the key panel unit 12. At this time, the external switch 16 When a call signal is input from the call signal, the call signal is input to the corresponding trunk line card 1A of the universal slot 2 of the keep phone 3 through the backplane interface line 9, and also to the ring detect unit 14 at the same time. do. At this time, the ring detecting unit 14 detects a ring signal carried in the input external call signal and rings the bell. Then, when the operator hears the ring tone and picks up the handset 15, the trunk line card 1A processes the voice signal of the other party's caller and sends it to the handset 15. Therefore, the operator confirms the extension number of the desired receiver from the other party's caller, and then presses the extension number through the key panel unit 12, and the main processor 4 recognizes this and allocates a channel to the corresponding extension card 1N. give. Then, a call connection signal is input from the trunk line card 1A of the universal slot 2 to the corresponding station card 1N, so that the call connection signal, for example, a voice traffic signal, is transmitted through a backplane interface line 9. The signal is matched via 11). Then, the call connection signal signal-matched by the transformer 11 is input to the wired telephone 17 via the module jack 10 to make a call between an external caller and an extension user. At this time, the main processor 4 displays the call state on the LCD panel 13 in letters or numbers through a display control signal.

On the other hand, if the card inquiry mode is determined during the card inquiry mode determination step (S2), if the card inquiry mode is set, the process proceeds to the credit card mode execution step (S4) to read the magnetic code signal of the credit card to use as a server of the card service company. Send the acknowledgment signal and wait. Then, after the credit card mode execution step (S4) proceeds to the approval determination step (S5) to determine whether the use approval signal is input from the server of the card service company. At this time, if it is determined during the approval determination step (S5) that the use approval signal of the currently read credit card is not transmitted from the server of the card service company, proceeds to the error signal output step (S6) and the error according to the use of the credit card Outputs alarm sound or text display signal. However, if the result of the determination in the approval decision step (S5) is transmitted from the server of the card service company, the approval message of the currently read credit card proceeds to the card inquiry termination step (S7) and the result according to the payment of the credit card. The card is notified to the server of the card service company, and the result data is output to the outside to terminate the card inquiry function.

In other words, when the user presses a card inquiry service button (not shown) installed on the key panel unit 12 of the keep phone 3, the main processor 4 recognizes this and switches from the call mode to the card inquiry mode. The card inquiry program stored in the memory unit 6 is read and executed. At this time, when the user inserts the credit card into the head unit 5, the main processor 4 reads and analyzes the magnetic code signal of the credit card and sends the card information to the server of the card service company. 4) inputs the corresponding card information signal to the trunk line card 1A of the universal slot 2 via the backplane interface line 9. Then, the CO line card 1A of the universal slot 2 processes the inputted card information signal by a predetermined signal and then transmits it to the server 18 of the card company via the external exchange 16. Accordingly, the server 18 of the card company analyzes the input card information signal, and transmits the processed information signal to the keep phone 3 via the exchange 16 to approve the use of the card or to indicate that the card cannot be used. Then, the processing information signal of the server 18 is input to the main processor 4 via the backplane interface line 9 after being subjected to a constant signal processing by the trunk line card 1A of the universal slot 2. At this time, if the processing information signal is a signal indicating that the use of the card, the main processor (4) causes the buzzer (8) to emit an alarm sound notifying the use of the card. However, the main processor 4 notifies the processing information signal input from the server 18 of the card company to inform the approval of the use of the card through the LCD panel 13 and requests to input a password. Then, when the card holder enters the password of the card through the key panel unit 12, the main processor 4 recognizes and processes it, and then outputs the result to the printing unit 7 and outputs the processing result to the card company. The card inquiry function is terminated by resending to the server 18.

As described above, the present invention has a head unit capable of reading a magnetic code signal of a credit card and a memory unit having a built-in program for controlling the same. In addition, since the card inquiry function is provided, there is an advantage of significantly improving the versatility of the keep phone.

In addition, according to the present invention, since the card inquiry can be executed by integrating a separate complicated card inquiry device into the keep phone with a simple circuit configuration, the convenience of use is also significantly improved.
