Abstract

PURPOSE:To prevent a paper jam of a receipt form, by carrying an unprinted receipt form in the carrying direction by prescribed length, when the receipt form is cut after printing. CONSTITUTION:After all the transaction information to the same customer has been printed to a receipt form, an issue stamp and a data in case of issuing a receipt to the next customer are printed on the receipt form. Subsequently, a CPU3 applies a driving activating signal to a cutter driving circuit 14. The circuit 14 drives a cutter 24, and makes it cut the receipt form automatically. In this case, a paper feed signal generating circuit 16 applies a carrying signal to a carrying driving circuit 13 in accordance with an output signal from the circuit 14. The circuit 16 carries the receipt form by length corresponding to an interval between the cutter and the cutter edge. In this way, when issuing a receipt of a customer, a paper jam of a receipt form can be prevented.

The 0 display unit 10, which is also provided to the conveyance drive circuit 13 and the cutter drive circuit 14, displays registered information or various information based on arithmetic processing. The printing unit 11 prints registration information, various information based on arithmetic processing, and issue year data such as a store seal provided from the issue year setting circuit 12 on receipt paper, journals, and the like.

The conveyance drive circuit 13 conveys the receipt paper every time registration information and the like are printed on the receipt paper. The cutter 1111 (1114) drives a cutter 24 shown in FIG. 2, which will be described later, when the changeover switch 15 is in the closed state.

In FIG. 2III, which is a cross-sectional view of the cutting mechanism installed in the ECR which forms the foreground of the present invention and which is applied to the present invention, a receipt paper 21 is conveyed to an issuing port 23 by a paper feed roller 22. The cutter 24 is driven based on the output signal from the cutter drive SM path 14. A cutting blade 2'-5 is provided at a predetermined distance t from the cutter 24 in the direction in which the receipt paper 21 is conveyed.

FIG. 3 is a 70° chart for explaining the operation of the ECR which forms the background of this invention and is applied to this invention. FIG. 4 is a flowchart for explaining detailed information on the receipt issuing operation in the conventional ECH.

Next, a case in which a receipt is issued using a conventional ECR will be described with reference to FIGS. W41 to FIG.

First, the operator operates numeric key 1 to input the number of transaction products purchased by Ii\E. The key presence signal output from numeric key 1 is sent to C via key encoder 2.
Given to PU3 and received. The CPLI 3 uses the address counter 7 to store data in the RAM based on the numerical data input from the numerical keys in step (abbreviated as S in the diagram) 1.
The address of a predetermined area of 8 is specified, and the numerical data is stored in the RAM 8. Next, the operator operates the function keys 4 to input the classification or department code of the transaction product. Therefore, the key discrimination circuit 5 discriminates which department the product corresponds to based on the key human input signal output from the function key 4, and the CPU 31C
give. The CPU 3 uses the RAM 8 via the input/output control 11 circuit 9 based on the department data input in step 2.
The CPLI 3 reads out the unit price data of the corresponding department stored in a predetermined area of the RAM 8. Then, in step 3, the CPLI 3 calculates the quantity of the traded product x the unit price of the traded product, and stores the calculation result in a predetermined area of the RAM 8. Make me remember. Accordingly, in step 4, the CPU 3 provides data on the transaction amount to the display 1110, and also provides data on the amount of the transaction product, the unit price of the transaction product, and the transaction amount to the printing unit 11. Therefore, the transaction amount is displayed on the receiving section 10. At the same time, the quantity, unit price, and amount of the transaction product are printed on the receipt 1t21.
3, the printing unit 1 is printed by the conveyance drive circuit 13 in step 4.
The receipt llA21 of No. 1 is driven. Take control, CP
In step 5, U3 determines whether transaction information registration processing for all products has been performed.

That is, if transaction information registration processing for all products has not been performed, operations from steps 1 to 4 are repeated.

As described above, when the transaction information registration process for all products is performed, the operator finally inserts the termination instruction key included in the function keys 4 in step 6. Based on this, the CPU 3 calculates the total transaction amount for one customer in step 7, and stores the total transaction amount for one customer in a predetermined area of the RAM 8 in step 8. In response, the CPU 13 causes the display unit 10 to display the transaction total amount in step 9 and prints the transaction amount on the printing unit 11.
At the same time, printing is performed on the receipt paper 21 and a journal (not shown), and the receipt paper 21 of the printing section 11 is driven by the conveyance drive circuit 13.

As mentioned above, upon completing the registration process, the operator receives payment for the customer's transaction.

Then, the operator operates the quantity key and the deposit key of the function key 4 to input deposit amount data from the customer. Accordingly, the CPU 3 calculates the deposited amount minus the total transaction amount in step 10, displays the change amount on the display section 10, and causes the printing section 11 to print it on the receipt paper 21.

Subsequently, the receipt paper 21 is issued in step 11. That is, when the total key indicating that the transaction processing with the customer has been completed is operated in step 101, the CPU 3 activates the transport drive circuit 13 in step 102.
The receipt paper 21 is conveyed by one line only. Accordingly, C
In step 103, the PU 3 causes the publication year setting circuit 12 to give data on the publication year to the printing unit 11, and prints the publication year on i! ll111 to print on the receipt paper 21.

Then, in step 104, the CPU 3 causes the transport drive circuit 13 to drive only the row corresponding to the publication year (line 11 in the flowchart). Subsequently, in step 105, the CPUA causes the printing unit 11 to print the date. In response, CPLJ3 provides a drive enable signal to cutter drive circuit 1114 in step 106. Therefore, the cutter drive circuit 14 drives the cutter 24 and causes the cutter 24 to cut the receipt paper 21 . The receipt is then handed over to Ganfu.

On the other hand, when manually cutting and issuing the receipt paper 21, the switch 15 is opened and the receipt paper 21
is conveyed by a length t and cut by the cutting blade 25.

However, in the conventional ECR, since the receipt @ 21 is not fed after automatically cutting the receipt paper 21, the leading edge of the receipt paper 21 is stopped near the issuing port 23. For this reason, in conventional ECR,
Subsequently, when issuing a receipt, the receipt paper 21 hits the bottom of the cutting blade 25 and enters the gap IIA,
There is a drawback that paper jams occur. In addition, in the conventional ECR, since the cutting blade 25 is provided at a predetermined distance from the cutter 24 in the transport direction of the receipt paper 21, when the receipt paper 1121 is cut manually or automatically, There is also the drawback that receipts with different margin sizes are issued.

- Therefore, an object of the present invention is to prevent paper jams of the receipt paper when the receipt paper 21 is automatically cut and issued, and to automatically or automatically cut the receipt paper 21 with an inexpensive and simple configuration. ECRtl allows you to issue receipts with the margins of the cut portion being the same size when you cut it! It is to provide.

In summary, this invention is based on the following: When the receipt paper is automatically cut after all the data specified for transaction processing for the same customer has been printed on the receipt paper, the unprinted receipt paper is conveyed for a predetermined length. The device is designed to be conveyed in the following directions.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 15 is a block diagram of an ECR according to an embodiment of the present invention. In FIG. 1, the same reference numerals as in FIG. 1 indicate the same or corresponding parts. In terms of configuration, this embodiment differs from FIG. 1 in that a paper feed signal generating circuit 16 is provided. The paper feed signal generation circuit 16 is connected to the cutter drive circuit 1
Based on the output signal of step 4, when a sheet of paper on which all registered information for the same customer is printed is cut by the cutter 24, only the length corresponding to the distance t between the cutter 24 and the cutting blade 25 is printed. A conveyance signal for conveying the blank receipt paper 21 in the conveyance direction is given to the conveyance drive circuit 13. Note that the interval t in this case is approximately 3.5-1, which corresponds to one line.

FIG. 6 is a flowchart for explaining details of the receipt issuing operation, which is a feature of this embodiment.

FIG. 7 is an illustrative diagram of a receipt issued by the ECR of this embodiment. Next, the operation of this embodiment will be explained with reference to FIGS. 2, 3, and 5 to 7. The transaction information registration process for the same official is performed in the same manner as steps 1 to 10 in FIG. WR - After all the transaction information for the customer has been printed on the receipt paper 21, the issue stamp and date when issuing the receipt to the next customer are printed on the receipt paper 21 as shown in FIGS. 6 and 7. It will be printed. More specifically, when the total key indicating that the transaction processing with the customer has been completed is operated in step 111, the CPL 13 transmits the data of the issuing stamp from the issuing setting circuit 12 to the printing unit 11 in step 112. The printing unit 11 prints an issue stamp on the receipt paper 21. In response, CPLJ3 issues an i mark in step 113.

The receipt paper 21 is driven by the conveyance N1111 circuit 13 by a row corresponding to (11 rows in the flowchart). Subsequently, the CPU 3 causes the printing unit 11 to print the date in step 114. The CPLI 3 then provides a drive enable signal to the cutter drive circuit 14 in step 115. Accordingly, the cutter driving circuit 114 is
The cutter 24 is driven to automatically cut the dotted line portion of the receipt paper 21 as shown in FIG. As a result, a receipt is given to the customer. At this time, step 1
16, the paper feed signal generation time 1116 is based on the output signal from the cutter drive circuit 15.
A carrier signal is given to 6. In response, the conveyance drive circuit 16 conveys the receipt paper 21 by a length corresponding to the distance t between the cutter 24 and the cutting blade 25 (which is one line in the flowchart). This is to prevent paper jams in the receipt 21 when the receipt is issued to the next customer.

On the other hand, when manually cutting the receipt paper 21 with the cutting blade 25 to issue a receipt, the switch 15 is opened.
be put into a state. Therefore, the cutter drive circuit 14 is no longer driven, and the receipt paper 21 is conveyed by one line in step 116.

Then, in step 117, the dotted line portion of the receipt paper 21 is cut by the cutting blade 25 based on the operator's operation.

As described above, according to the present invention, when the receipt paper 21 is automatically cut after all the data specified for transaction processing for the same customer has been printed on the receipt paper, the unprinted receipt paper is cut to a predetermined length. By conveying the receipt paper only in the conveying direction, a unique effect is achieved in that it is possible to prevent paper jams in the receipt paper when the receipt paper is automatically cut and issued. Further, according to the present invention, when a receipt paper is cut manually or automatically, the margin of the cut portion can be used to issue a receipt of the same size.
