Description

  The present invention relates to a payment apparatus used in a retail store or the like.

Conventionally, in a checkout device such as a POS register or cash register used in a retail store such as a supermarket, if a customer issues a receipt request during or after the checkout process, the clerk operates the receipt key. There is known a settlement apparatus capable of issuing a receipt using one printing unit and subsequently issuing a receipt (see, for example, Patent Document 1).
JP-A-5-325044

  At present, the prices of various materials are soaring, and the price of receipt paper and receipt paper is no exception. For this reason, the store wants to reduce the amount of printing paper used, such as receipt paper and receipt paper. However, the receipt issuing method described in Patent Document 1 requires printing paper for each receipt and receipt. There was a problem that it could not be reduced. In addition, the speed of the checkout process leads to the evaluation of the store by the customer, but the clerk needs to operate the receipt issuance key every time there is a request for issuing a receipt. There was a problem of being slow.

  The present invention has been made in order to solve the above-described problem, and provides a payment apparatus that can reduce the number of print sheets and further increase the speed of the payment process even when a receipt is issued. With the goal.

  The present invention calculates a purchase price, which is the total price of registered purchased products, and prints a receipt on one side of a sheet having two sides in a settlement apparatus that issues a receipt when the purchase price is settled. And a second printing unit that prints a receipt on a surface different from the surface of the paper on which the receipt is printed.

  Further, the present invention includes a cutting unit that cuts the paper, a control unit that compares the length of the receipt with the length of the receipt, and controls the cutting unit based on the comparison result. This is a settlement apparatus characterized by this.

  Further, the present invention provides the length of the receipt when the characters of the receipt are printed in parallel with the direction in which the paper is conveyed, the direction of the characters of the receipt, and the paper. The controller determines the direction of characters to be printed on the receipt based on the length of the receipt when printed so that the direction in which the sheet is conveyed is orthogonal to the length of the receipt. The second printing unit prints the receipt in the direction of the character determined by the control unit.

  According to the first aspect, when issuing a receipt, it is possible to reduce the number of print sheets and further improve the settlement processing speed. According to the second aspect of the present invention, since the checkout apparatus automatically determines and cuts the required length of the printing paper, the printing paper can be surely printed without missing both items of the receipt part and the receipt part. can do. According to claim 3, the length of the receipt part, the length of the receipt when the direction of the letter of the receipt and the direction in which the paper is conveyed are printed in parallel, and the letter of the receipt Compare the length of the receipt when it is printed so that the direction of the paper and the direction in which the paper is conveyed are orthogonal, and the direction of the letters in the receipt and the direction in which the paper is conveyed are parallel To determine whether to print the receipt or to print the receipt so that the direction of the letters on the receipt and the direction in which the paper is conveyed are orthogonal, the amount of print paper used and the appearance of the receipt The receipt part can be printed in consideration of the above.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of a settlement apparatus according to the present embodiment. In the example shown in the figure, the settlement apparatus includes a CPU 101, a RAM 102, a ROM 103, a display unit 104, an operation unit 105, a drawer unit 106, a clock 107, a communication unit 108, a first thermal head control unit 109, A second thermal head control unit 110, a cutter unit 111, a first platen roller driving unit 112, and a barcode scanner 113 are provided.

  The CPU 101 controls the settlement apparatus. The RAM 102 operates as a flag, a register, and a work area for the CPU 101 to operate, and also stores a PLU (Price Look Up) file, a receipt format, a vertical writing receipt format, a horizontal writing receipt format, and the like. The vertical receipt and horizontal receipt will be described later.

  The ROM 103 stores a program for operating the CPU 101. The display unit 104 displays the settlement result and the like to the store clerk and the customer. The operation unit 105 receives an operation by a store clerk. The drawer unit 106 stores product prices and the like. The clock 107 measures time (year / month / day / hour / minute / second). The communication unit 108 communicates with a store controller and other checkout devices. The first thermal head control unit 109 controls the operation of the first thermal head so that dots are printed on one side of the double-sided thermal roll paper. The second thermal head controller 110 controls the operation of the second thermal head so that dots are printed on a surface different from the surface of the double-sided thermal roll paper printed by the first thermal head controller 109. The cutter unit 111 cuts a print sheet described later under the control of the CPU 101. The first platen roller driving unit 112 includes a stepping motor and rotates a first platen roller described later. The barcode scanner 113 reads the barcode of the product and acquires the product price and the like.

  FIG. 2 is a diagram showing the configuration of the printing mechanism in the present embodiment. The printing mechanism includes a double-sided thermal roll paper 201, a first platen roller 202, a second platen roller 203, a first thermal head 204, a second thermal head 205, and a cutter 206.

  The double-sided thermal roll paper 201 is a paper on which a receipt and a receipt are printed. The double-sided thermal roll paper 201 is thermal paper, and heat is applied by the first thermal head 204 and the second thermal head 205 to print characters.

  A specific operation of the printing mechanism will be described. The first platen roller 202 includes a rotation drive mechanism (not shown), and the double-sided thermal roll paper 201 is pulled out by the rotation of the rotation mechanism. The first thermal head 204 prints a receipt on one side of the double-sided thermal roll paper 201, and the second thermal head 205 prints a receipt on the other side of the double-sided thermal roll paper 201. As a result, a receipt is printed on one side of the double-sided thermal roll paper 201, and a receipt is printed on the other side. After the receipt and receipt have been printed, the cutter 206 cuts the double-sided thermal roll paper 201. The CPU 101 determines the position at which the double-sided thermal roll paper 201 is cut. The determination method will be described later.

  The CPU 101 controls the operation of the printing mechanism. Further, the RAM 102 stores information on the contents to be printed on the receipt and the receipt. Further, the second platen roller 203 is not provided with a driving unit, and the double-sided thermal roll paper 201 is pulled out only by driving the first platen roller 202.

  Next, the procedure for determining the length of the double-sided thermal roll paper 201 on which the receipt and the receipt are printed and the format of the receipt will be described with reference to FIG. FIG. 3 is a flowchart showing a flow of operations for issuing a receipt and a receipt in the present embodiment.

  (Step S301) The store clerk reads the information of the product purchased by the customer using the barcode scanner 113 and registers it in the settlement apparatus. Note that the store clerk may register information on products purchased by the customer in the checkout apparatus using the operation unit 105. Based on the information read by the barcode scanner 113 or the information received by the operation unit 105, the CPU 101 of the checkout apparatus stores information on the products purchased by the customer in the RAM 102, and calculates the total price of the products. Thereafter, the process proceeds to step S302.

  (Step S <b> 302) When the clerk registers information on all the products purchased by the customer in the settlement apparatus, the clerk presses a “clamp key” such as a current key provided in the operation unit 105. The CPU 101 determines whether or not the “tightening key” provided in the operation unit 105 has been pressed. If it is determined that the button has been pressed, the process proceeds to step S303; otherwise, the process returns to step S301.

  (Step S303) Based on the merchandise information purchased by the customer stored in the RAM 102 in step S301, the CPU 101 determines the contents to be printed on the receipt. Further, the CPU 101 calculates the length of the receipt based on the printed contents of the receipt. Thereafter, the process proceeds to step S304. As the number of products purchased by the customer increases, the length of the receipt also increases. Further, the length of the receipt in the present embodiment is the length in the direction in which the double-sided thermal roll paper 201 is conveyed. The printed contents of the receipt are as shown in FIG. 4, for example.

  FIG. 4 is a view showing an example of the printed contents of a receipt in the present embodiment. In the example shown in the figure, the printed contents of the receipt include a word to be transmitted to the customer, a date and time when the receipt is issued, a person in charge name, a product name, a product price, and store information.

  (Step S304) The CPU 101 determines whether or not the length of the receipt calculated in step S303 is longer than the length of the vertical writing receipt set in advance. If it is determined that the length of the receipt is longer than the length of the vertical receipt, the process proceeds to step S307. Otherwise, the process proceeds to step S305. In the vertical receipt, the orientation of characters printed on the receipt (defined in this embodiment as the direction from the top to the bottom of the characters (the direction of the arrow 500 in FIG. 5)) and the double-sided thermal roll paper 201 are conveyed. 5 is a receipt printed so that the direction of the head is parallel to the direction, for example, as shown in FIG. In addition, the length of the vertical writing receipt in this embodiment is the length of the direction in which the double-sided thermal roll paper 201 is conveyed.

  FIG. 5 is a diagram showing an example of the print contents of a vertical receipt in the present embodiment. In the example shown in the figure, the printed contents of the vertical writing receipt are the words “receipt”, the address field of the receipt, the amount of money, the word to convey to the customer, the stamp pasting field, the date, and the store information. included. The length of the vertical receipt is determined in advance without depending on the number of products purchased by the customer. In addition, the length of the vertically written receipt is stored in the RAM 102 in advance.

  (Step S <b> 305) The CPU 101 controls the first thermal head 204 to print a receipt on one side of the double-sided thermal roll paper 201, and controls the second thermal head 205 to set the other side of the double-sided thermal roll paper 201. Print a vertical receipt. Thereafter, the process proceeds to step S306. Note that the receipt and the vertical receipt are printed on different sides of the double-sided thermal roll paper 201. In addition, the printing start position of the receipt and the vertical writing receipt is the same position of the double-sided thermal roll paper 201. For example, the CPU 101 controls the printing mechanism to start printing the receipt and the vertical writing receipt from a position 5 mm from the front end of the double-sided thermal roll paper 201.

  (Step S306) The CPU 101 controls the cutter 206 to cut the double-sided thermal roll paper 201 based on the length of the vertical writing receipt. Thereafter, the process ends. Note that, in step S306, since the length of the receipt is equal to or less than the length of the vertical writing receipt based on the determination in step S304, even if the double-sided thermal roll paper 201 is cut based on the length of the vertical writing receipt. The paper is not cut during the printing of the receipt, and a blank is formed at the bottom of the receipt. A receipt having a margin at the bottom of the receipt is as shown in FIG. 6, for example.

  FIG. 6 is a view showing an example of a receipt having a margin at the bottom in the present embodiment. In the illustrated example, the receipt includes a receipt portion 601 and a margin portion 602. The receipt unit 601 prints the print content determined in step S303. Nothing is printed in the margin part 602.

  (Step S307) The CPU 101 determines whether or not the receipt length calculated in step S303 is longer than the preset horizontal receipt length. If it is determined that the length of the receipt is longer than the length of the horizontal receipt, the process proceeds to step S310, otherwise the process proceeds to step S308. In the horizontal receipt, the direction of characters printed on the receipt (defined in this embodiment as the direction from the top to the bottom of the characters (the direction of the arrow 700 in FIG. 7)) and the double-sided thermal roll paper 201 are conveyed. This is a receipt printed so that the direction is orthogonal, for example, as shown in FIG. In addition, the length of the horizontal receipt in this embodiment is the length of the direction in which the double-sided thermal roll paper 201 is conveyed. The horizontal receipt is longer than the vertical receipt. Also, horizontal receipts look better than vertical receipts, so if the customer purchases many items and the receipt is long, the receipt is horizontal.

  FIG. 7 is a diagram showing an example of the printed contents of the horizontal writing receipt in the present embodiment. In the example shown, the printed contents of the horizontal receipt include the text “Receipt”, the date, the address field of the receipt, the amount, the stamping field, the wording to the customer, and the store information. It is. The length of the horizontal receipt is determined in advance without depending on the number of products purchased by the customer. Further, the length of the horizontal receipt is stored in advance in the RAM 102.

  (Step S308) The CPU 101 controls the first thermal head 204, prints a receipt on one side of the double-sided thermal roll paper 201, controls the second thermal head 205, and controls the other side of the double-sided thermal roll paper 201. Print a horizontal receipt. Thereafter, the process proceeds to step S306. Note that the receipt and the horizontal receipt are printed on different sides of the double-sided thermal roll paper 201. Further, the printing start position of the receipt and the horizontal writing receipt is the same position of the double-sided thermal roll paper 201. For example, the CPU 101 controls the printing mechanism to start printing a receipt and a horizontal writing receipt from a position 5 mm from the front end of the double-sided thermal roll paper 201.

  (Step S309) The CPU 101 controls the cutter 206 to cut the double-sided thermal roll paper 201 based on the length of the horizontal writing receipt. Thereafter, the process ends. In step S309, since the receipt length is equal to or less than the length of the horizontal receipt according to the determination in step S307, even if the double-sided thermal roll paper 201 is cut based on the length of the horizontal receipt, the receipt Will not be cut in the middle of printing, leaving a blank at the bottom of the receipt. The receipt with a margin at the bottom of the receipt is as shown in FIG. Further, since the double-sided thermal roll paper 201 is cut based on the length of the horizontal writing receipt, the printed receipt is as shown in FIG.

  (Step S310) As in step S308, the CPU 101 controls the first thermal head 204, prints a receipt on one side of the double-sided thermal roll paper 201, controls the second thermal head 205, and double-sided thermal roll paper. A horizontal receipt is printed on the other side of 201. Thereafter, the process proceeds to step S311.

  (Step S311) The CPU 101 controls the cutter 206 to cut the double-sided thermal roll paper 201 based on the length of the receipt. Thereafter, the process ends. In step S311, the receipt length is longer than the horizontal receipt based on the determination in step S307. Therefore, even if the double-sided thermal roll paper 201 is cut based on the receipt length, the horizontal receipt is printed. Will not be cut in the middle, and there will be a margin at the bottom of the horizontal receipt. Receipts with margins at the bottom of the horizontal writing receipt are as shown in FIG. 8, for example.

  FIG. 8 is a diagram showing an example of a horizontal receipt with a margin at the bottom in the present embodiment. In the illustrated example, the horizontal receipt includes a receipt part 801 and a margin part 802. The receipt section 801 is printed with the contents as shown in FIG. Nothing is printed in the margin part 602. In addition, a cut line is printed at the boundary between the receipt part 801 and the margin part 802. This makes it easier for the customer to cut the blank portion 802 with scissors or the like. Also, cutting the margin 802 is convenient when the customer keeps the receipt or submits it somewhere.

  In addition, an example of receipt printing in step S311 is as shown in FIG. FIG. 9 is a diagram showing an example of the printed contents of a receipt in the present embodiment. In the example shown in the figure, the printed contents of the receipt include a word to be transmitted to the customer, a date and time when the receipt is issued, a person in charge name, a product name, a product price, and store information. In the illustrated example, the receipt does not include a blank portion.

  As described above, according to the present embodiment, since the receipt is printed on one side of the double-sided thermal roll paper 201 and the receipt is printed on the other side, the printing paper can be reduced. Moreover, since the receipt can be issued without performing the operation for issuing the receipt, the speed of the settlement process can be further improved. In addition, since the payment apparatus automatically determines and cuts the necessary length of the double-sided thermal roll paper 201, the double-sided thermal roll paper 201 is surely printed on the double-sided thermal roll paper 201 without missing both items of the receipt part and the receipt part be able to. In addition, the length of the receipt part, the length of the vertical writing receipt, and the length of the horizontal writing receipt are compared to determine which format is used to print the receipt. The receipt can be printed in consideration of the appearance of the receipt.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes designs and the like that do not depart from the gist of the present invention. For example, in the present embodiment, a receipt and a receipt are printed using a double-sided thermal roll paper. However, the present invention is not limited to this, and a receipt and a receipt are printed on an ordinary paper using an ink jet print or an ink ribbon. Also good. Further, different printing methods may be used for the front and back of the paper.

  The determination of whether the length of paper cutting is based on a receipt or a receipt may be determined based on the number of products purchased by the customer or the number of operations for registering products.

  In addition, when printing a vertically written receipt, the presence or absence of a stamp sticking field may be determined according to the total amount of the receipt to further save paper.

  In addition, the total amount of the receipt becomes negative at the time of return, but in this case, only the receipt may be printed and the receipt may not be printed. Similarly, when the registered product is canceled, the total amount of the receipt becomes 0. In this case, only the receipt may be printed and the receipt may not be printed.
