printer is used for printing information concerning settlement. The PIN pad is used for customer's inputting his or her personal identity number.

Fig. 1 is a timing chart of settlement processing performed by the conventional CAT. Fig. 1 shows a case in which settlement processing, is. performed· for three customers. First, information, al. to be. settled, for one customer is inputted, and. stored, which, information comprises card data, settlement' amount data and·, personal identity number, data. Then., a telephone: number of the host computer is dialed, so that the host computer is called. Consequently, the. information al is transmitted to the host computer. The host computer: performs settlement processing, based on. the transmitted information al, to obtain information bl indicating the result of settlement. The obtained information bl is transmitted to the CAT. The transmitted information bl indicating the result of settlement is displayed: on the display in the CAT. Consequently, settlement processing for one customer is terminated, whereby settlement information of the next customer can be inputted. The same·, processing, as described above is performed for the. next customer.

In the conventional. CAT, as described, above, the settlement information of one customer can not be inputted until the settlement processing for the previous customer is terminated, and thirty seconds or more are required for communication processing, between the CAT and the host computer. Thus, one customer must wait for a long, time until settlement processing for the previous customer is terminated.

Fig. Ί is a timing chart according to an embodiment of the present invention.

Figs. 8A and 8B are flow charts for explaining an operation according to an embodiment of the present invention, where Fig. 8Ά shows input processing of information concerning settlement and display processing of information indicating the result of settlement, and Fig. 8B shows communication processing.

Referring now to Figs. 2 to 8B, the operation according to an embodiment of the. present invention will be described. In the present embodiment, the CPU 6 performs multitask processing based on a program stored in the ROM 9, so that the input processing of information concerning settlement, the communication, processing and the display processing of the result of settlement are performed in parallel.

When an operator performs continuously settlement processing for a plurality of customers, the operator first inputs information concerning, settlement for the first customer.. More specifically, the operator first designates the form of settlement, i.e., immediate settlement processing with the cash card, credit processing with the credit card or the like (in the step S 1). The designation is achieved by operating the cash card key 21 or the credit card key 22. Then, the operator inserts a card into the card reader 4. The card reader 4 reads card data from the inserted card (in the step S 2), Then, the operator operates the ten-key array 25 to input a settlement amount (in the step S 3). Then, a customer operates the PIN pad 5 to input the PIN data ( in the step S 4). The CPU 6 stores the inputted information concerning settlement- in the communication buffer 11 in the RAM 10 (in the step S 5). The above described input processing corresponds to input processing of information al in first processing shown in Fig. 7.

The CPU 6 determines, whether or not information concerning settlement is stored in the communication buffer 11 (in step S 21). When the information concerning settlement is stored, the CPU 6 connects the MODEM 8 with the host computer. 30 through a telephone line by dialing (in the step S22). -The CPU 6 then reads the information concerning settlement from the communication buffer 11, to transmit the same to the host computer 30 (in the step S 23). The host computer 30 performs settlement processing based on the transmitted information concerning settlement. The host computer 30 debits a customer's account for the amount to be settled when the cash card is used while registering, the amount to be settled on a file when the credit card is used. The host computer 30 may be employed both for the cash card and the

1.290849 credit card. Alternately, the host computer 30 for the cash card and the host computer 30 for the credit card may be separately provided-. The host computer: 30 transmits to the CAT 1 the obtained information, bl indicating the result of settlement. The CPU 6 in the CAT 1 is responsive to the reception:.of the: information bl for indicating the result of settlement.for storing the information bl in the communication buffer 11 (in the step S 24). Then, the CPU 6 turns the LED 32 on for lighting in order to indicate that information indicating the result of settlement which has not been displayed yet is stored in the communication buffer. 11 (in the step S 25), as well as sets, the undisplay flag in the area 105 in the communication buffer 11. The above described communication, processing corresponds to first communication, processing in the first processing, shown, in Fig. 7. The CPU 5 determines whether or not information concerning settlement which, has. not been, transmitted to the host computer. 30 exists, in the communication, buffers 11 and 12 (in the step S 26). In general, when unprocessed data exists., communication processing of the data is performed (in the steps. S 23 to 25). On the other hand, when unprocessed data does, not exist, processing for hanging up a telephone, line, is performed (in the. step S 27). In this case, since the information, concerning settlement is stored in the communication buffer 12 during the first communication processing as described below, the program proceeds from the step S 26 to the step S 22.

Since the CAT 1 has a multitask function, the operator which finished inputting the information concerning settlement for the first customer can input information concerning settlement for the next customer during the communication processing.for the first customer. The input processing for the second customer corresponds to input processing of information a2 in second processing shown in Fig. 7. Since data has already been stored in the communication buffer 11, the inputted information, concerning, settlement is stored in the communication buffer 12. When inputting of the information concerning settlement- for the second custoraer is terminated, the operator, waits, until the communication processing for the first customer is terminated, confirms that the LED 32 in the display 3 is turned on for lighting, and commands to display the result of settlement (in the step S 11). This command, is achieved by operating the settlement result display key 27. The CPU 6 is responsive to the operation of the settlement result display key 27 for reading out data from the communication buffer 11 having the undisplay flag set therein to display the same on the display 3. The CPU 6 allows displaying a card company name data included; in the card data and a settlement amount as the first display data, (in the step S 12), and allows displaying an account number included in the card data and the result of settlement in response to the operation of the set key 29 ( in the steps S 13 to S 14). Then, the CPU 6 is responsive to the operation of the set key 29 for turning off the LED 32 (in the steps S 15 to S 16), to set the display flag in the area 106 in the communication, buffer. 11. The display processing, of the result of settlement- corresponds to display processing of the information bl indicating the result of settlement in the first processing, shown in Fig. 7. Data in the buffer area having the display flag set therein is replaced by information concerning, settlement for the next customer when, it is inputted.

Since the information concerning settlement for the second, customer is inputted during the communication processing for the first customer, second communication processing for the second customer is performed without hanging up the line, after the. first communication processing for the first customer is terminated, as shown in Fig. 7. In addition, when the second communication processing for the second, customer, is performed, information concerning, settlement for a third customer is inputted, so that third communication processing for the third customer is performed subsequently to the second communication processing for the second customer.

Meanwhile, the CPU 6 turns the LED 31 on for light,.:.·: during the time period from the time when the line betweer. the CAT 1 and the host computer 30 is connected to the time when the line is hung. up.

Second Embodiment

Structure of a CAT according to a second embodiment is the same as that according, to the first embodiment shown in Figs. 2 to 5.

Fig. 9 shows a storage area in a RAM 10. As shown in Fig. 9, according to the present embodiment, a storage area 110 is provided with N communication buffers 111 to UN. Settlement form data, card data, settlement amount data, PIN data, settlement result data and display/undisplay flag are stored in the communication buffers, respectively, as in the communication buffers shown in Fig. 6.

Fig. 10 is a timing chart according to the present, embodiment. Figs. 11A to 11B are flow charts for explaining an operation according to the present embodiment, where Fig. 11A shows input processing of information concerning, settlement and display processing of the result of settlement, and Fig. 11B shows

- 17 ·' ··')

1230843 communication processing. Referring now to Figs. 2 to 5 and. Figs. 9 to 11B, the operation according to the present embodiment will be described. In the same manner as described in the first embodiment, input processing of information concerning.settlement is performed for a first customer (in the steps S 31 to S 34). The inputted information concerning settlement is stored, in. the communication, buffer 111 (in. the.step S 35). An operator determines whether or not· there exists information concerning, settlement which, has not been inputted, yet ( in the step S 35). When there exists information, concerning settlement which has not been inputted. yet&gt; the information concerning.settlement is. inputted subsequently to the input processing for. the first customer.. The number of times of input processing of. the information concerning, settlement is. restricted, by the. number, of communication buffers. The CPU 5 determines, whether, or not the number of times of input processing· of the information, concerning, settlement. is. N· (in the. step S 37). When the number, of times, of input processing becomes. N, the communication buffer becomes full, so that an input operation is terminated.

According to the present embodiment, input processing is continuously performed for, for example, four customers. The input processing, corresponds to input processing of information al in first processing, input processing of information a2, in second, processing, input processing of information. a3 in. third processing and input processing of information a4 in fourth processing shown in Fig. 10. The CPU 6 determines, whether, or. not information concerning settlement is. stored, in any of the communication buffers (in the step. S 51). When the information concerning, settlement is stored, communication processing is performed, in. the same.· manner, as described, in the first embodiment⁴ (in the steps S 53 to S 57). The communication, processing.corresponds to first communication, processing, second communication, processing, third communication processing, and. fourth communication processing, shown in. Fig. 10. The. CPU 6 turns the LED 32 on for lighting, when, first communication, processing, is terminated.

The operator operates, the. settlement result displaykey 27 to display the result of settlement. on the display 3 when, the input processing is terminated for, for example, four customers (in the. step S 41). The CPU 6 reads out information concerning settlement and information indicating the result of settlement from the communication, buffer 110, to display the. same on the display 3, in the same, manner, as described in the first embodiment (in the steps S 42 to S45). According to the present embodiment, the CPU 5 determines whether or not there exists information indicating the result of settlement which, has. not been displayed yet every time the CPU 6 displays data from one communication buffer (in the step S 46), and turns the LED 32 off when display processing of all information indicating the result of settlement is terminated (in. the step.S 47). It is determined based: on the display/undisplay flag stored in each of the communication, buffers, whether, or not there exists information. indicating, the result.of settlement which has not been displayed, yet. The display processing of the information indicating, the. result of settlement corresponds, to display processing, of the result.bl of settlement, display processing of the result b2 of settlement, display processing, of the result b3 of settlement and display processing, of. the result b4 of settlement shown in Fig. 10.

Meanwhile, the CPU 6 turns the LED 31 on for lighting while communication processing, is. performed..

According to the present embodiment-, input processing of information concerning, settlement, can be continuously performed for a plurality of customers, during communication between the CAT 1 and the host computer 30.

Although the present invention, has been described and illustrated in detail., it is clearly understood that the same is by way of illustration and example only and. is not to be taken, by way of limitation, the spirit and scope of the present invention being limited only by the terms· of the appended claims.
