BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receipt issuing device and a program for issuing a receipt to a customer who has visited a store and purchased a product.

[0002]

2. Description of the Related Art Stores that sell goods, dishes, drinks, or services (including use of exercise facilities and accommodation facilities, massages, etc.) to customers who come to the store as products are usually provided with an electronic cash register or POS (Point). Of Sale) A receipt issuing device such as a terminal is installed. The receipt issuing device is intended to easily perform accurate accounting operations and sales amount management. When the customer registers (enters) the purchased product (sales product), the details of the transaction related to the sale (the name (or corresponding symbol) for each sales product, the amount thereof, the total amount, the date, ) Is printed on a recording paper.

[0003] The receipt is given to a customer. Paying attention to this, a receipt issuing device capable of printing not only transaction contents but also image information such as messages and advertisements has been commercialized. As a result, attempts to increase the customer's willingness to purchase through receipts have been actively made.

[0004]

A conventional receipt issuing apparatus capable of printing image information prints the image information on a surface (front surface) on which the details of the transaction are printed.
For this reason, there is a problem that a receipt to be issued becomes longer by an amount corresponding to the printing of the image information, and a running cost in issuing the receipt is significantly increased. Giving customers a long receipt for each type of product they purchase is
This is not desirable because it may give a bad impression to the customer that it is troublesome to receive.

[0005] It is an object of the present invention to provide a receipt issuing apparatus capable of issuing a receipt on which image information other than transaction contents is printed at a lower running cost.

[0006]

SUMMARY OF THE INVENTION A receipt issuing apparatus according to the present invention is an apparatus for printing, on a recording sheet, the details of a transaction relating to the sale of a product to a visiting customer and issuing the receipt as a receipt. Product registration means for performing,
First printing means for printing the transaction contents of the goods registered by the goods registration means on one surface of the recording paper, and advertisement printing data to be printed on the other surface of the recording paper; Means for acquiring the information according to the length of the transaction content printed by the first means, and printing on the other surface of the recording paper by the first printing means using the advertisement printing data acquired by the information acquiring means. And second printing means for printing an advertisement corresponding to the length of the transaction content.

In the above arrangement, the information acquisition means acquires advertisement printing data as information, and the second printing means employs the data acquired by the information acquisition means on the other side of the recording paper. It is desirable to print an advertisement on the website. The information acquiring means acquires a plurality of types of data according to the length of the transaction content printed by the first printing means,
The second printing means prints an advertisement of a type corresponding to the length of the transaction content printed by the first printing means on the other surface of the recording paper using the data obtained by the information obtaining means. Is desirable.

[0008] Further, when the customer pays the price using a credit card, the information acquiring means acquires data for printing at least the contents of use of the credit card. At least the credit card usage is printed on the other side of the recording paper using the acquired data, and the recording paper on which the credit card usage is printed is charged to the company that issued the credit card for payment. It is desirable to be able to issue it as a slip for doing so. The first and second printing means reverses and conveys a portion of the recording paper, on which one or the other surface has been printed, to the same place again through a previously prepared conveying path, and thereby conveys one sheet. It is desirable that this is realized by one printing means.

In the present invention, when a receipt or a slip is issued, information to be printed on the back side is obtained, and printing is performed on both the front side and the back side. For receipts, for example, advertisements, messages to customers, coupons, discount coupons, etc. are printed on the back side as necessary, and for slips, for example, one of the information to be printed in two pieces is printed on the back side I do. In this way, as a result of using the back side effectively, a receipt printed with image information other than transaction contents,
Alternatively and / or, the voucher can be issued at lower running costs.

Embodiments of the present invention will be described below in detail with reference to the drawings. <First Embodiment> FIG. 1 is a diagram for explaining a circuit configuration of a receipt issuing device according to a first embodiment and a device connected thereto.

The receipt issuing device 100 is one in which the present invention is applied to, for example, an electronic register or a POS terminal. As shown in FIG. 1, a CPU 101 for controlling the entire device 100 and a store for operating the same are used. A display unit 102 for displaying data to be notified to another person (cashier), a keyboard 103 operated by the cashier, a printing device 104 for performing printing on recording paper by, for example, a thermal recording method, and a CPU 101 executing. A program memory 105 for storing programs and various data; an interface 106 for relaying data exchange with a barcode scanner (hereinafter simply referred to as a scanner) 121 for reading a barcode attached to a product or its price tag; For example, a personal computer (hereinafter referred to as a PC) A communication control unit 107 for relaying the exchange of data with the user 131, a display 108 for displaying information to be notified to the customer, and a storage device 109 for storing various data and working. Have been.

As other components, although not particularly shown, a drawer unit for controlling the opening and closing of a drawer for storing money and vouchers, a card reading unit for reading a magnetic stripe formed on a credit card or the like. , And so on. However, they will not be mentioned here unless otherwise required.

The store in which such a receipt issuing device 100 is installed is, for example, selling goods to customers who come to the store as goods. However, the products sold by the store are not limited to items, but may be dishes, drinks, or various services (including use of exercise facilities and accommodation facilities, massages, and the like).

The PC 131 is a receipt issuing device 10
0 is connected by a LAN or a cable. It is the maintenance of the issuing device 100 (printable POP (Poin
t OfPurchase advertising) image data is deleted, rewritten, or added, etc.), and data stored in the storage device 110 is read and stored or processed. The POP1 data in the figure is the image data.

The PC 131 can be connected to the Internet 132 via a public line, for example. An advertiser (advertising company or manufacturer) that commissioned the presentation of POP to customers via the Internet 132
The server 133 can access the server 134 installed. Note that the connection with the server 134 (establishment of a link) is, for example, the Internet 1
ISP (Internet S
After making a dial-up connection with the service provider, the connection is designated by designating the URL (Uniform Resource Locator) of the server 134.

In the present embodiment, the POP is printed on the back surface of the receipt (the surface opposite to the surface on which the details of the transaction are printed). Each image (image) data for printing the POP is stored in the storage device 109 as, for example, a file. A non-volatile storage device 109 is used so that such data can be held. Specifically, for example, a RAM, a hard disk device backed up by a battery, or a combination of a hard disk device and a RAM (there is no need to back up with a battery at this time). The POP image data stored in the storage device 109 is, for example, data downloaded by the PC 131 from the server 134 of the advertiser 133 via the Internet 132.

The type of POP to be printed on the receipt is set in advance by the store. As a result, it is possible to inform customers in a timely manner of information such as new merchandise, merchandise focused on sales, or events through the receipt. The POP to be printed does not need to be the same for all customers, and a plurality of types may be set in consideration of gender, age, and the like. In that case, the POP to actually print
The type of can be selected by the cashier. As a matter of course, the customer may select the type of POP to be printed on the receipt.

The operation of the above configuration will be described. When the power is turned on, the CPU 101 reads out and executes a program stored in the program memory 105 to start control of the entire apparatus 100. The control is performed in response to a cashier operation on an input device such as the keyboard 103 or the barcode scanner 121, or in response to a request from the PC 131 received via the communication control unit 107. Here, in order to avoid confusion, the cashier will be described as operating only the keyboard 103 for convenience.

The customer carries the product he / she wants to purchase to the cashier (receipt issuing device 100) and pays for the purchase. At that time, the cashier, for each product, for example, the product code and the number thereof, the keyboard 1
The registration is performed by inputting from 03, and after all the registrations are completed, a subtotal key which is one of the function keys arranged on the keyboard 103 is operated. By operating the subtotal key, the prices (total) of the products are displayed on the display devices 102 and 108, respectively. Thereafter, the customer deposits money, inputs the amount of the deposited money from the keyboard 103, and operates a function key (hereinafter referred to as a closing key) indicating that the input has been completed. By operating the key, one transaction on the receipt issuing device 100 in the sale of the product is closed, and the details of the transaction (the name (or the code corresponding thereto) for each registered product, the number thereof, the amount thereof, and the like) A receipt is printed with the price, deposit amount, change amount, date, etc.). The cashier gives the customer the receipt and change, if any, in addition to the goods.
As such, the cashier is adapted to the customer.

The CPU 101 responds to an operation on the keyboard 103 by such a cashier to display the display 10.
The user can change the display content of the
To print and issue a receipt. Thereby,
The receipt issuing device 100 is operated so that the cashier can perform the above-described operation. The display units 102 and 108
Is changed by the CPU 101 creating image data of data to be displayed on the CPU and writing the image data into a memory (for example, a VRAM) mounted thereon.

POP is printed on the back of the receipt. Receipt issuance, including printing of the POP, is performed as follows. Figure 2
This will be described in detail with reference to various explanatory diagrams in FIG. FIG.
As a part of the printing device 104, the receipt issuing device 10
FIG. 4 is a diagram illustrating a printing mechanism mounted on a print mechanism. This is an excerpt of a main configuration for printing on a roll paper 201 installed as a recording paper in a receipt issuing device 100 and issuing a receipt.

In the present embodiment, it is assumed that the roll paper 201 having a thermosensitive recording layer formed on both sides is used. As shown in FIG. 2, a printing mechanism capable of performing printing on both sides of the printing head includes two printing heads (thermal heads) 202 and 203 having different surfaces that come into contact with the recording paper fed from the roll paper 201, and the two printing heads.
02, 203, and the roll paper 20
Platens 204 and 205 for pressing against the recording paper fed from 1, an auto cutter 206 for cutting off a portion of the fed recording paper to be issued as a receipt 201 a, and feeding the recording paper from the roll paper 201 And a pair of rollers 207 and 208 for carrying the sheet. The print head 202 is for printing on the front side of the roll paper 201, that is, for printing the transaction contents of the product, and the other print head 203 is for printing on the back side, that is, for POP printing. In the drawings, a to c denote the distance on the transport path between the auto cutter 206 and the print head 202, the distance on the transport path between the auto cutter 206 and the print head 203, and the distance between the print head 203 and the print head 20, respectively.
The distance on the transport path between the two is shown.

One of the rollers constituting each pair of rollers 207 and 208 has a stepping motor (not shown) mounted as a power source for feeding out and transporting the recording paper from the roll paper 201, for example. Power is transmitted. The auto cutter 206 is
The roll paper 201 is cut by moving the blade from the state shown in FIG. The movement from the state shown in FIG. 2 to a state where the blade is housed in the groove and the movement for returning from the state to the state shown in FIG. 2 are performed by, for example, a solenoid.

The printing device 104 includes, for example, loads such as a stepping motor, a solenoid, and print heads 202 and 203, various driving circuits thereof, and a CPU for controlling the various driving circuits. Accordingly, the receipt 201a is issued by the CPU of the printing
In accordance with an instruction from the PU 101, printing is performed by controlling various drive circuits in accordance with data transmitted from the PU 101, and then the printed portion is separated from the roll paper 201 by the auto cutter 206. It has become. In this manner, a receipt 201a having both sides printed thereon is issued as shown in FIG.

As shown in FIG. 3B, the receipt 201
When the POP is printed on the back surface of a, the P is compared with when the POP is printed on the front surface together with the transaction contents.
The length of the receipt 201a (the length in the transport direction) is reduced by the amount of OP. For this reason, the roll paper 201 can be saved, and accordingly, the running cost in issuing the receipt 201a is reduced. Also, the time required for the issuance is shorter because the length of the receipt 201a is shorter. Therefore, the receipt 201
a can be delivered to the customer more quickly. This means that it is possible for the store to avoid deterioration in service quality due to printing of POP (image information) on the receipt 201a.

By the way, the receipt with the POP printed as image information on the back side is issued as roll paper 201.
If a POP that has already been printed is used, the POP can be performed without printing the POP on the back surface of the receipt.
However, the POP on the back of the receipt is required to be appealing as an advertisement, and must be suitable for the situation. For example, POP for products that should be introduced to customers, such as new products that have started selling and products that stores are focusing on selling
Need to be

With the roll paper 201 on which the POP is printed in advance, the receipt 201a on which the POP of the product to be introduced to the customer is printed cannot be issued unless the roll paper 201 is replaced according to the date and time or the customer. . But,
The exchange of the roll paper 201 is not possible because it is not desirable in order to prolong the waiting time of the customer, so that it cannot be performed substantially. The roll paper 201 on which the POP is printed is ordered by a special order, but the surplus roll paper 201 must be discarded in some cases. They mean that running costs increase. For this reason, when the roll paper 201 on which the POP is printed in advance is used, it is not easy to issue the receipt 201a on which the appropriate POP is printed, so that there is a problem that lack of timeliness and a running cost increase. There is a problem such as doing.

Each of the print heads 202 and 203 has, for example, a heating element arranged on one line. As a result of driving the heating elements on the print heads 202 and 203, circular black dots (black dots) are formed on the receipt 201a as shown in FIG. The width t (unit: mm) of the black dot is the length of one line in the transport direction.

As shown in FIG. 3A, the transaction contents (data) such as the type (including price) and subtotal of the product purchased by the customer, the amount of money deposited from the customer, etc., are as shown in FIG. Separate lines are printed separately. As shown in FIG. 5, the CPU 101 converts the image data for each line into data in the line within a range in which the number of dots (DOT) in the transport direction of the receipt 201a does not exceed a predetermined number of dots, as shown in FIG. Create by expanding to a pattern. From this, the roll paper 20
1 is printed on the recording paper fed out from the roll paper 2 by the CPU of the printing device 104 by driving the stepping motor.
The print heads 202 and 203 are driven according to the data sent from the CPU 101 while the recording paper is fed out by one line (width t) from 01. Thereby, printing on both sides of the receipt 201a as shown in FIG. 3 is realized. In FIG. 5, “DOT / line” represents the number of dots in one line in the transport direction in units of dots. Although not described in detail, both the print heads 202 and 203 are brought into pressure contact with the recording paper fed from the roll paper 201 only when the print heads are driven.

Next, the operation of the receipt issuing device 100 for responding to the operation performed by the cashier as described above,
In particular, the operation at the time of issuing the receipt 201a will be described in detail with reference to various flowcharts shown in FIGS. 6 to 8 are realized by the CPU 101 reading and executing a program stored in the program memory 105.

FIG. 6 is a flowchart of the back / front print control processing. The print control process is performed when the cashier operates the close key on the keyboard 103 to instruct the closing of the sales transaction, in other words, the receipt 201a.
When the content to be printed is determined, the receipt 201a
This is a process that is executed in order to issue First, the print control process will be described in detail with reference to FIG.

As shown in FIG. 2, the print head 202 is at a distance a from the auto cutter 206 and the print head 203 is at a distance b therefrom. At the start of the print control process, the auto cutter 206 is in a state where it exists at the position shown in FIG. 3 of the next receipt 201a to be issued. From this, the contents of the transaction on the surface,
On the back side, POP printing is immediately started, respectively. Since the POP printing has not been started, the POP to be printed can be changed even immediately before.

As shown in FIG. 3A, the receipt 201
The size of the character (font) printed on the surface of a differs depending on the item. However, here, in order to avoid confusion, for convenience, the number of dots in the transport direction for one line, D
The OT / line is treated as being unchanged by the item. Similarly, regarding the number of dots in the POP transport direction, the difference due to POP is ignored. Hereinafter, unless otherwise specified, the number of dots (row) is the
Dots (lines) in the direction (vertical direction) of transporting 01a
I will use it to indicate a number.

First, in step S601, a print line n to be printed to represent the contents of a transaction is obtained. The print line n is, for example, a line for printing a product registered by a cashier, a line for printing items such as a subtotal, a deposit amount (cash deposit), and fishing, and a line for printing a solid line or a broken line, or a blank line. The number of lines including the number of lines
(A)). Since the number of lines for printing items such as subtotals and the number of lines for printing solid lines, etc., are predetermined numbers of lines, the calculation of the number of printed lines n is based on the sum of those lines and the number of items registered by the cashier. This is done by adding the number of types.

Step S602 following step S601
Then, the value obtained by multiplying n, which is the number of dots for one line, and DOT / line, which is the number of dots for one line, and the width t of one dot (= n × DOT / line × t) are used as the width of POP dots. t
Is subtracted from the value obtained by subtracting the distance c (= the number of POP dots × t−c). If the former value is larger than the latter value, that is, it is determined that the content of the transaction is one POP, and the process shifts to step S612. If not, that is, if the former value is less than or equal to the latter value, it is determined so and the process proceeds to step S603.

The reason for subtracting the distance c for calculating the latter value is that the print head 202 for front side printing and the print head 203 for back side printing are distances (distances on the transport path) as shown in FIG. This is because, since it is separated by c, printing on the back surface can be continued for the distance c even after printing on the front surface ends. From this, the fact that the former value is larger than the latter value, that is, moving to step S612, means that the transaction content is printed at least as long as one POP printing can be completed. ing. Conversely, when the former value is equal to or less than the latter value, that is, when the process proceeds to step S603, it means that the printing of the transaction content is not performed as long as the printing of one POP is completed.

In step S603, the value obtained by subtracting the distance c from the value obtained by multiplying the number of POP dots by the width t (= POP)
(Dot number × t−c) multiplied by each value of DOT / line, which is the number of dots for one print line, and the value of width t (= n × DOT / line × t: transaction content) The number obtained by subtracting the number of dots required for printing (.) Is substituted for the variable Δg. In this way, the variable Δg is set to the length (the receipt 201a) that is insufficient to complete the printing of one POP.
After that, the processing proceeds to step S604.

In step 604, the value of the variable Δg is set to 1
The value obtained by multiplying DOT, which is the number of dots for a row, by a width t (=
DOT / row × t). If the value of the variable Δg is smaller than the latter value, it is determined so and step S608 is performed.
Move to If not, that is, if the value of the variable Δg is equal to or greater than the latter value, it is determined that this is the case, and the process proceeds to step S605.

In step S605, the above constant A is set as the number of dots (feed dots) (lines) to be added to the print lines excluding the last line of the transaction contents in order to increase the space between the lines. In the following step S606, as the number of feed dots to be added to the last line, a value obtained by multiplying the value of the constant A, the print line n, and the value of the width t is subtracted from the value of the variable Δg, and the value obtained thereby is used as the width. A value (= (Δg−A × n × t) / t) divided by the value of t is set. When the number of feed dots is set as described above, the flow proceeds to step S607 to print the POP to be printed.
After substituting 1 into the variable m as the number of
Move to The setting of the number of each feed dot is performed by substituting the corresponding values into the character line FEEDDOT and the last line FEEDDOT, which are variables prepared to hold the set values. Step S
At 606, if the value obtained to be substituted for the last line FEEDDOT is smaller than 0, 0 is substituted.

On the other hand, in step S608, to which the process proceeds when it is determined in step S604 that the value of the variable Δg is smaller than the value obtained by multiplying DOT / line by the width t, the value of the variable Δg is relatively small. Last line FEEDDOT
And the value obtained by dividing the value of the variable Δg by the value of the width t (= Δg / t)
Is assigned. After that, in step S607, the variable m is set to 1
After that, the process moves to step S609.

As described above, in the present embodiment, if the length for printing the transaction content is insufficient to complete the printing of 1 POP, the number of dots in the print line is increased to compensate for the shortage. ing. Thereby at least one
One POP is printed on the receipt 201a in a complete form (see FIG. 3).

In step S609, the receipt 201a
To print on the front and back sides of the recording paper while feeding out the recording paper from the roll paper 201 to issue
4 performs a back / front print execution process. After the printing on the front side and the back side is completed by executing the printing execution processing, the process proceeds to step S610, and the printing device 104 further causes the printing paper to be further fed from the roll paper 201, and then the printed portion is printed. An AUTOCUT execution process for cutting by the auto cutter 206 is executed. Accordingly, in step S611 to which the process proceeds after issuing the receipt 201a, a store name stamp printing process for causing the printing device 104 to print information predetermined by the store, such as the store name, is executed. In this way, after the position of the auto cutter 206 on the receipt 201a to be issued next is set to the position shown in FIG. 3, a series of processing is ended. The information to be printed at the time of executing the shop name stamp printing process includes “THA” in the receipt 201a shown in FIG.
NK YOU CALLAGAIN ".

When it is determined in step S602 that the former value is larger than the latter value, the process proceeds to step S61.
In 2, the printing line n, the number of dots for one line, DOT /
A value obtained by adding the value of the distance c to the value obtained by multiplying each value of the line and the width t, and dividing the addition result by the number of POP dots (the total number of lines in the transport direction in units of dots). (=
(N × DOT / row × t + c) / number of POP dots) is substituted for the variable m. In this way, after substituting the number of POPs that can be printed on the back side with the length for printing the transaction details into the variable m, the process proceeds to step S613.

In this embodiment, such a value is referred to as a variable m.
To the receipt 2 while changing the type.
POP that can be printed on the back side of 01a is printed. Thereby, the receipt 201a is more efficiently used as an advertising medium.

In step S613, the value of the decimal part of the variable m is compared with 0.3. If the value of the decimal part is smaller than 0.3, it is determined so and the process proceeds to step S614 to convert the value of the variable m to an integer by deleting the decimal part (“m = mod in the figure). (Indicated as “(m)”), and then proceeds to step S615. If not, that is, if the value of the decimal part is 0.3 or more, it is determined so and the process proceeds to step S615 without executing the processing of another step.

Even if POP is printed, if the ratio of the printed portion to the whole is small, the printed portion does not function as an advertisement and may be recognized as mere noise. In this case, there is no point in printing the POP. For this reason, in the present embodiment, it is considered that the printing rate is small, and PO is considered to be simply recognized as noise.
P is not printed. 0.3 is a value determined as a criterion for determining whether or not to perform the printing. If the number of dots to be printed is smaller than 0.3, the decimal part of the variable m is truncated.
POP printing whose ratio is less than 0.3 is avoided.

In step S615, the character line FEEDD
Substitute the default value for OT. Following step S616
Then, 0 is substituted for the last line FEEDDOT. After performing such substitution, the process proceeds to step S609 described above. Note that the default value assigned to the character line FEEDDOT is, for example, 0.

Next, the back / front print execution processing executed as step S609 will be described in detail with reference to the flowchart shown in FIG. The printing execution process is a process for controlling the printing device 104 to print on the front surface and the back surface while feeding out the recording paper from the roll paper 201.

The data to be printed as transaction contents, ie, the type (including the number and unit price) of merchandise registered by the cashier, subtotal, cash deposit, etc. (see FIG. 3)
The information is stored in an area secured in the storage device 111 for the storage (hereinafter, referred to as transaction information BUFFER) in units of rows. From this, the printing of the transaction content is
Data is read out one line at a time from the FFER. The calculation of the print line n in step S601 is performed by counting the number of lines of data stored in the transaction information BUFFER.

First, in step S701, 1 is assigned to a pointer PT, which is a variable prepared for reading data from the transaction information BUFFER in units of rows. In the subsequent step S702, the POP image data to be initially printed stored in the storage device 111 is copied to an image BUFFER, which is an area secured in the storage device 111, and the BUFFE
1 is assigned to a DOT pointer PP, which is a variable prepared for reading out image data on R in units of rows.
After that, the procedure moves to step S703. Note that 1 assigned to each pointer is a value representing the line located at the beginning.

In step S703, the data of the line specified by the value of the pointer PT is
Read from FER. Step S70 to be executed next
In step 4, the read data is expanded into a font image, that is, bitmap image data, and the image data is stored in a frame BUFFER, which is an area secured in the storage device 111. When the image data is stored, the process proceeds to step S705, in which a feed dot for expanding a blank portion between lines is set in the frame BUFF.
Add to ER. If the line from which data was read in the immediately preceding step S703 is not the last line, the line is added to the line specified by the value of the character line FEEDDOT (a line in units of dots. Hereinafter, this line is referred to as a DOT line for convenience). In other words, if the line from which the data is read is the last line, the process is performed for the dot line specified by the value of the last line FEEDDOT. After the addition of such feed dots, the process proceeds to step S706.

In step S706, the frame BUFF
The number of dot rows of the image data stored in the ER is substituted for the variable fn. In the following step S707, a one-frame print control process for causing the printing device 104 to print the image data stored in the frame BUFFER and the POP image data is executed. When the print control process is executed, the value of the pointer PT is incremented in step S708, and then the process proceeds to step S70.
Move to 9.

In step S709, it is determined whether or not the value of the pointer PT is a value representing the row next to the last row. When the printing of the last line is completed, the value of the pointer PT is a value representing the line next to the last line, so the determination is YES, and a series of processing ends here. Otherwise, the determination is no and the process returns to step S703, where
The subsequent processing is executed in the same manner.

As described above, the above steps S703 to S7
The processing loop formed in step S09 is repeatedly executed until the determination in step S709 becomes YES. As a result, while reading data line by line from the transaction information BUFFER, the data and the POP image data corresponding to the data are read out on the roll paper 2.
01 is printed on the recording paper fed from 01.

FIG. 8 is a flowchart of the one-frame print control process executed as step S707. Finally, the print control process will be described in detail with reference to FIG. First, in step S801, a pointer FP, which is a variable prepared for reading image data from the frame BUFFER in dot row units, is used.
Is substituted for the value of 1 representing the dot row located at the top of the row. In the following step S802, the image BUFFER
Then, the value obtained by subtracting the value of the pointer PP from the value of EOF representing the last dot row of the image data of the POP copied in (1) (= EOF-PP) is compared with the value of the variable fn. If the value is equal to or greater than the value of the variable fn, that is, the frame BUF
While printing FER image data,
If the printing of the image data of the target POP is not completed, it is determined to that effect, and the flow shifts to step S805. Otherwise, it is determined so and the process proceeds to step S803.

In step S803, it is determined whether the value of the variable m is less than 1 having a decimal part. If the target POP cannot be printed next to the current POP (the last POP to be printed), the determination is N.
The result is O, and the flow shifts to step S804 to store image data for forming a blank portion (indicated as "NUL image data" in the drawing) in the image BUFFER and to assign 1 to the pointer PP, and then to step S805. Move to Otherwise, the decision is YE
In S, the process moves to step S805.

As described above, the number of dots to be printed (line)
Is smaller than 0.3, the fractional part of the variable m is truncated to avoid printing POP whose ratio is less than 0.3. The avoidance is realized by executing the above step S804.

In step S805, the image data of the dot row specified by the value of the pointer PP is converted to the image BU.
Read from FFER. In a succeeding step S806, the value of the pointer PP is incremented. After the increment, the process moves to step S807.

In step S807, the value of the pointer PP is compared with the value of EOF. If the value of the pointer PP is equal to or greater than the value of EOF, it is determined that the pointer PP has been reached, and the flow shifts to step S813. Otherwise, the determination is no and the process moves to step S808, where step S8
05 to the print head 203
Then, the data is sent to the printing device 104 as data to be printed, and the printing is instructed. Then, the process proceeds to step S809.

In step S809, the image data of the dot row specified by the value of the pointer FP is read from the frame BUFFER. In a succeeding step S810, the read image data is stored in the print head 20.
In step 2, the data is sent to the printing device 104 as data to be printed, and the printing is instructed. After that, the value of the pointer FP is incremented in step S811, and then, in step S811.
The process moves to 812. After the printing, the roll paper 201
The instruction to the printing device 104 for feeding out the recording paper for one dot from is performed in step S810, for example.

In step S812, the value of the variable fn is decremented, and the value after the decrement is compared with 0. If the value after decrement is 0 or less, that is, if the printing of the image data stored in the frame BUFFER has been completed, this is determined, and a series of processing ends here. If not, it is determined so and the process returns to step S805. As a result, the image data is read from the frame BUFFER one dot row at a time while the image data and the PO are read.
The P image data is printed on the recording paper fed from the roll paper 201.

In step S813, to which the process proceeds when it is determined in step S807 that the value of the pointer PP is equal to or greater than the value of EOF, the value of the variable m is decremented, and the value after the decrement is compared with 0. If the value of the variable m after decrement is equal to or less than 0, that is, if all the POPs to be printed have been printed, it is determined that this is the case, and step S8 is performed.
Shift to 09. If not, the process proceeds to step S814, and the POP image data to be printed next, which is stored in the storage device 111, is copied to the image BUFFER, and 1 is set to the pointer PP. After the substitution, the process moves to step S809. In this way, if there is a POP to be printed next to the POP for which printing has been completed,
Printing is started immediately. Although a detailed description is omitted, in order to specify a POP to be printed next, for example, the number of POPs printed so far is counted.

In this embodiment, the PO according to the customer is
In order to print P, the receipt 201a is not printed from the beginning of the receipt 201a (see FIG. 3), but may be printed from the beginning. The printing start position may be arbitrarily selected by the store. <Second Embodiment> In the first embodiment, the print head (thermal head) 202 for printing on the front side is replaced with the print head (thermal head) 203 for printing on the back side of the roll paper 201. Is also equipped with a printing mechanism (see FIG. 2) located on the near side. In contrast, the second
In this embodiment, a printing mechanism whose positional relationship is reversed is mounted.

The structure of the receipt issuing device 100 according to the second embodiment is basically the same as that shown in FIG. 1 according to the first embodiment. Most of the operation is the same as in the first embodiment. From this,
The reference numerals used in the description of the first embodiment are used as they are, and only the parts different from the first embodiment will be described.

FIG. 9 is a diagram showing a printing mechanism according to the second embodiment. The printing mechanism is mounted on the receipt issuing device 100 as a part of the printing device 104 as described above. In the second embodiment, as shown in FIG. 9, a print head 901 for backside printing is positioned before a printhead 902 for front side printing with respect to the roll paper 201. They are arranged at a distance f on the transport path. With respect to the auto cutter 206, the print head 901 is separated by a distance d on the transport path, and the other print head 902 is separated by a distance e on the transport path. A pair of rollers 903 disposed between the print heads 901 and 902 is for feeding out and transporting the recording paper from the roll paper 201, and one of the rollers is configured to transmit power from a stepping motor. Has become. Reference numerals 904 and 905 in FIG. 9 denote platens for pressing the print heads 901 and 902 against the recording paper, respectively.

FIG. 10 is a view showing a receipt 201a issued by the printing mechanism. FIG. 1A shows the front surface, and FIG. 1B shows the back surface. 9 correspond to the distances df shown in FIG. 9, respectively. In the second embodiment, as shown in FIG. 10 (b), unlike the first embodiment, the POP is
01a is printed from the top. This is because the distance d between the print head 901 and the auto cutter 206 is relatively large as shown in FIG. This is because the portion indicated by d in 10 (b) becomes large. In other words, the utilization efficiency of the back surface is greatly reduced. Note that the auto cutter 2 shown in FIG.
The position 06 indicates the receipt 201a where the auto cutter 206 exists at the time when the printing of the shop name stamp is completed.
This is the upper position, and the print heads 901 and 902 are located at distances d and e, respectively, from that position.

Next, the front / back print control processing executed in place of the back / front print control processing (see FIG. 6) in the first embodiment will be described in detail with reference to the flowchart shown in FIG. explain. First, step S1101
Then, it is determined whether or not the roll paper 201 is loaded. For example, a sensor that detects the open / closed state of the cover that covers the roll paper 201 detects that the cover is open (the
When the roll paper 201 is attached, it is recognized that the state has changed from the uncovered state to the closed state.
The determination is YES and the process moves to step S1102,
After the printing device 104 prints the POP for the distance f from the head only for the back surface, the process proceeds to step S1103. Otherwise, the determination is no and the process moves to step S1103.

In step S1103, a process of causing the printing device 104 to print the dot lines of the shop name stamp, the shop name stamp, and the POP on the front and back sides, respectively, is executed. In the following step S1104, transaction information B
The print line n is obtained by counting the number of lines of data stored in UFFER. After that, step S1
Move to 105.

In step S1105, a value (= n × DOT / line-f) obtained by subtracting the value of the distance f from the value obtained by multiplying the print line n by DOT / line, which is the number of dots for one line, is
The value is compared with the value obtained by multiplying the number of remaining dot lines of the POP by the value of the width t. If the former value is greater than or equal to the latter value, that is, if the length for printing the transaction content is long enough to print all one POP, it is determined that this is the case, and the process proceeds to step S1112. Transition. Otherwise, it is determined so and the process moves to step S1106. It should be noted that the value of the distance f is subtracted from the value obtained by multiplying the print line n by DOT / line, which is the number of dots for one line, immediately before the end of the printing of the transaction contents, by the distance f for the next receipt 201a.
This is because the minute must be printed. In FIG. 10, the remaining length of the POP at the time when the process of step S1105 is executed is indicated by g.

In step S1106, the variable m is set to 0.5.
Is assigned. After 0.5, after printing POP,
This is an arbitrary value set so as not to start printing the next POP. After substituting the value for the variable m, step S
The flow shifts to 1107, where values to be substituted for various variables (parameters) are set. Specifically, for the pointer PP, a value (actually, the current value of the pointer PP) representing the dot line located at the head of the image data not printed (remaining) in the image BUFFER is set. For the pointer PT, a value 1 representing a line located at the head of the transaction information BUFFER is set, and the transaction information BUFF is set.
The value representing the row (end row) of data to be processed last by FER is obtained by dividing the value of the distance f by a value obtained by multiplying the value of DOT / dot which is the number of dots for one row by the value of the width t. The value obtained by subtracting the value from the value of the print line n (= n−f / (DOT / line ×
t)) is set. After that, the procedure moves to step S1108. Note that the value obtained by dividing the value of the distance f by the value obtained by multiplying the value of the DOT / line by the value of the width t is expressed by a value having a decimal part so that the number of lines is not represented by a number having a decimal part. If there is a decimal part, an operation of converting the decimal part to an integer is performed, and the value after the operation is subtracted from the print line n.

Step S11 following step S1107
In step 08, front / back printing execution processing is performed to cause the printing device 104 to print on the front and back sides of the recording paper according to the value set in step S <b> 1107. After that, the procedure moves to step S1109. By executing the front / back printing execution process in step S1108, the state shifts to a state where the transaction content ends with printing for the distance f. This state means that the POP for the next receipt 201a is printed on the back side.
Is a state in which printing of. Therefore, in step S1109, values to be substituted into various variables (parameters) are set in accordance with the state. After that, the process shifts to step S1110 to execute the front / back print execution process according to the set value.

In step S1109, the current value is set for each of the pointer PP and the pointer PT, and the last line of the data to be processed last in the transaction information BUFFER is set to the last line. A value to be represented is set, and 1 is substituted for a variable m. As a result, by executing the front / back printing execution process of step S1110, all the transaction contents are printed on the front surface, and the POP is set to the distance f for the next receipt 201a on the back surface.
Minutes.

Step S following the step S1110
At 1111, an AUTOC for causing the printing apparatus 104 to perform POP printing for at least the distance e only on the back surface and then to cause the printing apparatus 104 to perform cutting by the auto cutter 206.
Execute UT processing. Thus, after the receipt 201a has been issued, a series of processing ends.

On the other hand, when it is determined in step S1105 that the former value is equal to or greater than the latter value, the process proceeds to step S1.
At 112, a value obtained by subtracting the value of the distance f from the value obtained by multiplying the variable m by DOT / line which is the number of dots for one line and the print line n (= n × DOT / line-f), The value obtained by multiplying the number of remaining dot lines of the POP by the value of the width t is subtracted, and the value after the subtraction is used as the number of dots of the POP (the total number of lines in the transport direction in units of dots). The result is divided by the multiplied value, and a value obtained by adding 1 (a value for POP for which printing has already started) to the value after the division is substituted for a variable m. After substituting the value representing the number of POPs that can be printed into the variable m in this way, the flow shifts to step S1113.

In step S1113, the value of the decimal part (value after the decimal point) of the variable m is compared with 0.3. When the value of the decimal part is 0.3 or more, the fact is determined, and the flow shifts to step S1107 to execute the subsequent processing in the same manner. If not, it is determined and
After performing the operation of truncating the decimal part of the variable m in step S1114, the flow shifts to step S1107. In this manner, as in the first embodiment, POP printing that cannot be expected to function as an advertisement because the printing ratio is small is avoided.

Next, at step S1108 or S
The front / back printing execution process executed as 1110 will be described in detail with reference to the flowchart shown in FIG. In the flowchart shown in FIG. 12, the processing contents are the same as the back / front print execution processing shown in FIG.
Alternatively, basically the same steps will be denoted by the same reference numerals and detailed description thereof will be omitted.

First, in step S1201, the value for the pointer PT set in step S1107 or S1109 is assigned to the pointer PT. In the following step 1202, similarly, the value for the pointer PP set in step S1107 or S1109 is assigned to the pointer PP. In the next step 1203 to be executed, the value representing the end line set in step S1107 or S1109 is substituted for the variable END. In that way, step S1107 or S1
After substituting the values set in step 109 into the corresponding variables, the flow shifts to step S703.

Steps S703, S704, and S70
In steps 6 to S708, the processing of each step is executed in the same manner as in the first embodiment. Step S to which the process proceeds after incrementing the value of the pointer PT in step S708
At 1204, it is determined whether or not the value of the variable PT is equal to a value obtained by adding 1 to the value of the variable END. Step S110
If the processing of the data up to the end row set in step 7 or S1109 is completed, the values become equal, so the determination is YES, and the series of processing ends here. Otherwise, the determination is no and the process returns to step S703 to execute the subsequent processing in the same manner.

The AUT in step S1111 shown in FIG.
In the OCUT process, the pointer P whose value has been updated by executing the front / back printing execution process in step S1110.
This is performed using P. The processing in step S1103 is
The processing is performed using the pointer PP whose value has been updated in the AUTOCUT processing or the processing of step S1102. Thereby, POP is printed accurately on the back surface.

In the second embodiment, by printing the POP from the beginning of the receipt 201a, most of the POP can be printed even if the length of printing the transaction details is short. Although printing is not necessarily completed, printing of one POP may be completed.

In the first and second embodiments, when a plurality of POPs can be printed on the back surface of the receipt 201a, a plurality of types of POPs are printed.
The OP may be repeatedly printed. <Third Embodiment> Many customers use a credit card for payment at a store. When a customer uses a credit card, in addition to the receipt given to the customer, a voucher for charging the card company that issued the credit card must be issued. Usually, a few sheets of paper must be issued as the slip. In the third embodiment, the slip can be issued in a smaller number.

The configuration of the receipt issuing apparatus 100 according to the third embodiment is basically the same as that shown in FIG. 1 according to the first embodiment. Regarding the operation, there are many parts that are the same or basically the same as those of the first embodiment. For this reason, only the parts different from the first embodiment will be described using the reference numerals assigned in the description of the first embodiment as they are. The reading of a credit card or a cash card is performed by the card reading unit.

FIG. 13 is a diagram showing a slip issued for a card company in the third embodiment when a customer uses a credit card. FIG. 1A shows the front surface, and FIG. 1B shows the back surface. On the back surface, a customer code (card number), an expiration date, a processing category, a store code indicating a store where the customer has used the card, and the like are printed as data of the credit processing unit.

In the third embodiment, as shown in FIG. 13, the transaction contents (receipt information) are displayed on the front side, and the usage contents of the card to be notified to the card company (data of the credit processing unit and transaction amount) are displayed on the back side. (Price) etc. and signature fields are printed. When printing is performed on both sides of the recording paper in this manner, the number of papers to be issued for a slip can be reduced in one transaction as compared with the related art in which necessary information is printed for each sheet. . Since the entire length can be shorter, the issuance of the slip is completed in a shorter time. As a result, not only can running costs be reduced, but also the speed of the work performed by the cashier is effective.

FIG. 14 is a flowchart of the transaction information printing process. The printing process may be performed by the cashier operating a close key on the keyboard 103, operating a dedicated function key (for example, a credit key) for instructing card payment, causing the card reading unit to read the card, or simply operating the card reader. This processing is executed to issue a receipt 201a and further a slip when the reading unit reads a card. Next, using FIG. 14,
The printing process will be described in detail. The printing process is realized by the CPU 101 reading and executing a program stored in the program memory 105.

First, in step S1401, it is determined whether or not a credit process is to be performed. When the cashier causes the card reader to read the available credit card presented by the customer for payment, the determination is YES and the step S1 is performed.
Move to 404. Otherwise, that is, if the customer pays for cash or a cash voucher (book coupon, etc.), the determination is no and the process moves to step S1402.

When the cashier causes the card reader to read the credit card, the receipt issuing device 100
The read information and the price (transaction amount) (hereinafter collectively referred to as credit data) are transmitted to the PC 131. The PC 131 relays the transmission of the credit data from the member store to the credit card company, or transmits the data to a center that provides a service such as acting on behalf of the company, and transmits information indicating whether the credit card can be used. Receive an authentication result. The authentication result is transmitted to the receipt issuing device 100. For this reason, although a detailed description is omitted, even if the credit card is read by the card reading unit, if the authentication result indicating that the card can be used is not received from the PC 131, step S is executed.
The determination in 1401 is not YES, and processing for responding to the determination is executed. Naturally, communication with the center is performed by the receipt issuing device 10.
0 may go.

In step S1402, the print data of the POP designated in advance is converted into an image BUFFE for backside printing.
Copy to R In the following step S1403, a first back / front print control process as shown in FIG. 6 is executed. By executing the print control processing, the customer receipt 20 is executed.
After issuing 1a, a series of processing ends. It should be noted that the print control processing is performed in step S1402 in the image BUFFE.
The processing contents are basically the same as those in the first embodiment except that the data copied to R is printed.

In step S1404, to which the determination in step S1401 is YES and the process proceeds, for example, a credit processing unit (see FIG. 9) generated from information read from the credit card by the card reading unit or data previously stored in the storage unit 109 13) to generate image data for printing, and store it in an area secured in the storage device 109 for work. In the following step S1405, data indicating the amount of money charged to the customer is developed to generate image data for printing,
Store it in that area. Thereafter, image data for printing a signature field for customers to sign and image data for printing a unique message stored separately for each credit card company in the storage device 109 are stored in the respective areas. Store (Step S
1407, S1407). When all the image data for printing the back side of the voucher is stored in the area in this manner, the process proceeds to step S1408.

In step S1408, the image data stored in the area is replaced with an image BUFF for back side printing.
Copy to ER. Next step S140
In step 9, a second back / front print control process is performed to print the image data copied to the image BUFFER on the back side and the data to be printed on the front side stored in the transaction information BUFFER on the front side. By executing the print control process, after issuing the slip as shown in FIG. 13, the flow shifts to step S1402 to issue the receipt 201a following the slip.

The second back / front print control processing in step S1409 is, for example, a length to be printed on each of the front side and the back side of the voucher (of course, the length in consideration of the distance c shown in FIG. 2). ) Adds a feed dot to the shorter one. Thus, printing on the front and back sides of the slip is completed.

In the present embodiment (first to third embodiments), two print heads are used to print on both sides of the recording paper fed from the roll paper 201. However, only one print head may be used. For example, as shown in FIG.
1, the print head 1
501, a platen 1502, a paper guide 1503, and a receipt discharge / feed guide 1504 may be provided.

In the printing mechanism shown in FIG. 15, a portion of the recording paper on which printing has been performed on one side by the print head 1501 passes through the transport path formed by the paper guide 1503 and passes through the print head 1501 again in a reversed state. It is supposed to. For this reason, the receipt 201a is issued, for example, as follows.

First, printing on one side is performed while the recording paper is fed from the roll paper 201, and when the printing is completed, cutting is performed by the auto cutter 206. After the cutting, the receipt discharge / feed guide 1504 is moved to the position shown in FIG. (To the right as viewed in FIG. 15). The recording paper 201a separated from the roll paper 201 by the auto cutter 206 is conveyed as it is, and starts printing on the other surface when the leading end reaches the print head 1501. The recording paper 201a on which double-sided printing has been performed in this manner is discharged outside the apparatus as a receipt 201a.
The receipt discharge / feed guide 1504, which has been moved to the position shown in FIG. 15 to convey the printed portion of the other surface in the discharge direction, discharges the receipt 201a, for example, and then returns to the original position (FIG. To the left).

In the printing mechanism shown in FIG.
1a, printing is performed separately on the front surface and the back surface. For a control method for printing on each surface, for example, in the first embodiment, in order to use the back surface more effectively, It is desirable to apply the method described in. Further, it is desirable that a plurality of types of paper guides 1503 having different lengths of transport paths to be formed can be mounted so as to be able to accommodate receipts 201a of various lengths.

The printing device 104 mounted on the receipt issuing device 100 employs a thermal recording system in which printing is performed by applying heat to recording paper. The printing system which can be employed in the printing device 104 is the thermal recording system. However, the present invention is not limited to this. Another printing method may be adopted.

In this embodiment, POP (advertisement) is printed as information on the back surface of the receipt 201a, but the information is not limited to advertisements such as POP. A message from a store to a customer, a coupon, a discount coupon, or the like may be printed as information. If the transaction content becomes long, it may be printed separately on both sides. As is clear from this, various information can be adopted as information to be printed on the back surface. The information may be stored in advance in the storage device 109 or the like, or may be received (acquired) from an external device such as the PC 131 as needed. Whether or not the information is printed on the back surface may be set arbitrarily at the store.

[0098]

As described above, according to the present invention, when a receipt or a slip is issued, information to be printed is acquired and printed on the back surface. For receipts, for example, advertisements, messages to customers, coupons, discount coupons, etc. are printed on the back side as necessary, and for slips, for example, one of the information to be printed in two pieces is printed on the back side I do. In this way, in order to use the back side effectively, a receipt printed with image information other than the transaction content, and / or
A slip can be issued at a lower running cost.
