Description

  The present invention relates to a cash register with a small display with a small display amount.

  In the conventional cash register, for example, an electronic cash register, when an error occurs, a message indicating the cause of the error and the subsequent procedure is displayed step by step as necessary ( For example, see Patent Document 1).

Also, even if you miss a message that is displayed when an error occurs and then automatically disappears, you can check the missed message later by displaying it again when an error redisplay operation is performed. Data input devices have also been known (for example, see Patent Document 2).
Japanese Patent Laid-Open No. 04-312199 JP 2001-306227 A

  As described above, in a conventional cash register such as an electronic cash register, it is possible to display a message indicating an occurrence factor and a subsequent procedure when an error occurs. In addition, when a message is missed, it can be displayed again.

  However, such a message display function is effective in a cash register having a display capable of displaying a plurality of lines of text data such as a CRT display or a liquid crystal display as a display unit for an operator. Therefore, the present invention cannot be applied to a cash register having only a small display with a small display amount that can display only the name and price of the product.

  Cash registers using small displays are cheaper than those with CRT displays and liquid crystal displays, and are therefore mainly used in small stores. However, in such stores, there are many cases where there is no operator who is familiar with the operation of the cash register. For this reason, when an error occurs, there is a case where the shopper waits for a long time because the method of dealing with the error is unknown, or the use of the cash register machine is stopped and a receipt cannot be issued.

  The present invention has been made based on such circumstances. The purpose of the present invention is that even if it is a cash register having only a small display device with a small display amount, the cause of occurrence of an error and the subsequent measures are taken. The purpose is to shorten the time required for recovery from an error state by making the procedure easy to be taught to the operator.

  The present invention solves the above-mentioned problems in a cash register having a receipt issuing means for issuing a receipt in which detailed data of a product purchased by one customer is printed together with a transaction number for specifying a product sales transaction with the customer. In order to achieve the purpose, an error explanation request key is provided. When the error explanation request key is operated when an error occurs, the receipt issuing means is operated to issue an error explanation receipt on which operation explanation data for canceling the occurring error is printed. is there.

  By taking such measures, even in a cash register that has only a small display with a small display amount, the operator can easily know the cause of the error and the subsequent procedure when an error occurs. It is possible to shorten the time required for recovery from the system.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In this embodiment, the present invention is applied to a single electronic cash register.

  FIG. 1 is a perspective view showing an external appearance of an electronic cash register 1 in the present embodiment. The electronic cash register 1 is provided with a keyboard 2, a mode switch 3 and an operator display 4 on the front side which is the operator side, and a customer display 5 is provided on the back side which is the customer side. . An RJ (receipt / journal) printer 6 that performs receipt printing and journal printing is built-in. The receipt paper printed by the RJ printer 6 is discharged from the receipt issuing port 7, and the journal paper is wound inside the main body. It is supposed to be. Further, the electronic cash register 1 is formed with a drawer 8 for storing cash or the like.

  The operator display 4 includes a text display unit 41 that displays a product name and price of a product that has been entered for sale in one or two lines, and a state display unit 42 that displays various states according to the light emitting state of the light emitting element. It is a small display with a small display amount.

  As shown in FIG. 2, the keyboard 2 has a numeric key 21 for numeric data, a plurality of department keys 22 each of which is preset with a department code for classifying each product, and an “amount”. Amount key 23, “×” multiplication key 24, “C” clear key 25, “subtotal” subtotal key 26, “deposit / cash total” closing key 27, “error explanation” error explanation request key 28, Various function keys such as a “cancel” cancel key 29 are arranged.

  FIG. 3 is a block diagram showing a main configuration of the electronic cash register 1. The electronic cash register 1 includes a CPU (Central Processing Unit) 11 as a control unit body. Also, a ROM (Read Only Memory) 12 in which fixed data such as programs and data tables are stored in advance, a RAM (Random Access Memory) 13 in which various memory areas for storing rewritable data are rewritable, A clock unit 14 for measuring the current date and time, an input / output (I / O) port 15 to which a signal from the mode switch 3 is input and an open command signal to the drawer 8 is output, the keyboard 2, a keyboard controller 16 that captures key signals corresponding to operation keys, a display controller 17 that controls data display on the operator display 4, a display controller 18 that controls data display on the customer display 5, and the RJ printer 6 includes a printer controller 19 for controlling the printing operation 6. The CPU 11, the ROM 12, the RAM 13, the clock unit 14, the I / O port 15, and the controllers 16 to 19 are connected by a bus line such as an address bus or a data bus.

  The mode switch 3 is a control switch for selecting various business modes such as “registration”, “inspection”, “settlement”, and instructing the CPU 11 to execute them. Incidentally, “registration” is a process for registering sales data of a product purchased by one customer in a predetermined memory area of the RAM 13 based on product data input by a combination operation of the numeric key 21 and the department key 22 of the keyboard 10. When the closing of the product purchased by one customer is declared by the operation of the closing key 27, the receipt on which the transaction details data such as the sales amount of the product purchased by the customer and the total amount is printed by the printer 6 is printed. This is the mode of work to be issued. “Check” is a mode of business in which product sales data registered in a predetermined memory area of the RAM 13 by registration work is totaled and a report is output as sales data. “Checkout” is a mode of business in which the product sales data registered in the predetermined memory area by the registration business is aggregated and output as sales data, and then the predetermined memory area is cleared as in the inspection business.

  Now, when an error occurs due to an erroneous key operation or the like, the electronic cash register 1 of the present embodiment displays error name data indicating the error content on the text display unit 41 of the operator display 4 to display the error. When the error explanation request key 28 is operated when an error occurs, the RJ printer 6 that is a receipt issuing means is operated to print operation explanation data for canceling the error that has occurred. And a function for issuing an error explanation receipt.

  In order to realize such a function, in the present embodiment, as shown in FIG. 4, an error name table 31 in which error name data indicating the type of error content is set for each error code set for each error type. As shown in FIG. 5, an error explanation table 32 in which operation explanation data for canceling the error is set for each error code is stored in the ROM 12 of the electronic cash register 1.

  Further, as shown in FIG. 6, a print data buffer 33 for accumulating and storing receipt print data and a print data saving memory 34 for temporarily saving receipt print data accumulated in the print data buffer 33 are electronically connected. It is formed in the RAM 13 of the cash register 1.

  Therefore, the electronic cash register 1 is configured so that when an error occurs, the CPU 11 executes the error processing shown in the flowchart of FIG. First, the CPU 11 detects an error code of an error occurring as step (ST) 1. In ST2, this error code is printed on journal paper by the RJ printer 6.

  Next, the CPU 11 acquires error name data set corresponding to the error code from the error name table 31 as ST3. In ST4, the error name data is displayed on the text display unit 41 of the operator display 4.

  Thereafter, the CPU 11 waits for key input in ST5. If it is detected in ST6 that the error explanation request key 28 has been operated, the CPU 11 executes an error explanation process specifically shown in FIG.

  First, in ST11, the contents of the print data buffer 33 are saved in the print data save memory 34, and the print data buffer 33 is cleared. Next, the CPU 11 acquires error explanation data set corresponding to the error code from the error explanation table 32 as ST12. In ST13, the error explanation data, the footer data printed on the last line of the receipt, and the header data displayed at the head of the next receipt are stored in the print data buffer 33.

  Normally, the footer data of a receipt is composed of a cashier code of a signed-on cashier, a transaction number that identifies a merchandise sales transaction, and a current time (transaction time) counted by the clock unit 14. However, in ST13, data of two items (a casher code and a transaction time) excluding the transaction number is stored in the print data buffer 33. The header data of the next receipt is composed of item data of store name / logo, setting message, transaction date and cash register number, and these item data are stored in the print data buffer 33 as they are.

  Next, the CPU 11 operates the RJ printer 6 in ST14 to collectively print the data in the print data buffer 33 on receipt paper and journal paper. After printing, a receipt cutting process is performed as ST15, and the cut receipt paper is issued from the receipt issuing port 7 as an error explanation receipt (error explanation receipt issuance control means).

  Thereafter, the CPU 11 returns the print data saved in the print data save memory 34 in ST16 to the print data buffer 33 and restores it. As described above, the CPU 11 ends the error explanation process, returns to ST5 of the error process, and waits for the next key input.

  FIG. 9 is an example of a purchase details receipt 50 printed and issued for a merchandise sales transaction with one customer processed by the electronic cash register 1 of the present embodiment. In the purchase details receipt 50, data 51 is receipt header data, data 52 is transaction details data, and data 53 is receipt footer data. Along with this receipt footer data 53, header data 61 for the next receipt 60 is printed, and at the same time, the receipt paper is cut along a cutting line 55 and a purchase detail receipt 50 is issued. In this purchase detail receipt 50, “1234” in the receipt footer data 53 is a transaction number, and this transaction number is normally incremented by one each time a registration closing of a merchandise sales transaction with one customer is declared. Therefore, if the merchandise sales transaction with the next customer ends normally, the transaction number “1235” is printed on the purchase details receipt 60 issued to the customer.

  By the way, it is assumed that the error of the error code [ERR001] occurs when the cashier makes an erroneous operation of pressing the department key 22 without entering the amount during the merchandise sales transaction with the next customer. In this case, the error name data “error with no number” set corresponding to the error code [ERR001] is called from the error name table 31, and the error name data “error with no number” is displayed on the operator display 4. Are displayed on the text display section 41.

  As a result, the cashier can know that a no-number error has occurred. Here, if the cashier knows an operation for canceling the state of no-number error, the error canceling operation may be executed. However, if the user does not know the operation for canceling the error state or forgets the operation, the operation for canceling the no-number error cannot be executed immediately. In such a case, the cashier presses the error explanation request key 28.

  Then, the error explanation data set in correspondence with the error code [ERR001] from the error explanation table 32 “Release the error with the C key. Please enter the amount and then press the department key.” Then, as shown in FIG. 10, the error explanation data 62 indicating the operation procedure for eliminating the error state is printed on the receipt 60. Further, receipt footer data 63 excluding the transaction number is printed on the receipt 60. Further, at the same time when the next receipt 70 is printed on the receipt header data 71, the receipt 60 and the receipt 70 are cut by the cutting line 64, and the receipt 60 is issued from the receipt issuing port 7 as an error explanation receipt.

  Therefore, the cashier can cancel the error state with no number by performing a key operation according to the content of the error explanation data 62 printed on the error explanation receipt 60. At this time, since the data in the print data buffer 33 is restored to the state before the error occurred, there is no need to redo the sales input for the merchandise sales transaction in which the error has occurred.

  As described above, according to the present embodiment, even in the case of the electronic cash register 1 having only a small display with a small display amount, the occurrence factor and the subsequent action can be performed in a short time by a simple operation when an error occurs. Since the operator can confirm the procedure, the time required for recovery from the error state can be shortened. As a result, the degree of waiting for the shopper due to the occurrence of an error is reduced, and the reliability of the store can be improved.

  By the way, the embodiment (hereinafter referred to as the first embodiment) has a print data buffer 33 for accumulating and storing receipt print data. The case has been described in which the present invention is applied to a batch printing type cash register which prints the stored receipt print data on receipt paper and issues a receipt. However, the present invention can also be applied to a sequential printing type cash register that prints product sales data on receipt paper every time sales data of products purchased by one customer is processed.

  Next, another embodiment (hereinafter referred to as a second embodiment) in which the present invention is applied to a sequential printing type cash register will be described with reference to the drawings. The second embodiment is also applied to a single electronic cash register 1 as in the first embodiment, and common portions are denoted by the same reference numerals, and detailed description thereof is omitted. .

  The electronic cash register 1 of the second embodiment is the same as that of the first embodiment in terms of its external configuration and hardware configuration, and will not be described with reference to FIGS. Similarly to the first embodiment, an error name table 31 and an error explanation table 32 are stored in the ROM 12. A print data buffer 33 is formed in the RAM 13. The print data buffer 33 holds the receipt print data for one customer until the merchandise sales transaction with the customer is completed. Here, the print data buffer 33 functions as print data holding means.

  Thus, in the electronic cash register 1 according to the second embodiment, when an error occurs, the CPU 11 executes the error processing shown in the flowchart of FIG. In ST6, when the error explanation request key 28 is operated, the CPU 11 is configured to execute an error explanation process specifically shown in the flowchart of FIG.

  That is, when entering the error explanation process, the CPU 11 first acquires error explanation data set corresponding to the error code from the error explanation table 32 as ST21. In step ST22, the RJ printer 6 is operated to print the error explanation data on the receipt paper and the journal paper. Next, the CPU 11 acquires the receipt footer data excluding the transaction number in ST23, operates the RJ printer 6, and prints the receipt footer data on the receipt paper and the journal paper. Further, the CPU 11 acquires the header data of the next receipt in ST24, operates the RJ printer 6, and prints the receipt header data on the receipt paper and the journal paper. After printing, a receipt cut process is performed as ST25, and an error explanation receipt is issued (error explanation receipt issuance control means).

  Thereafter, the CPU 11 operates the RJ printer 6 as ST26 to print the print data held in the print data buffer 33 on the receipt paper and the journal paper again. The CPU 11 ends the error explanation process, returns to ST5 of the error process, and waits for the next key input.

  In the second embodiment having such a configuration, after the sales input (department registration) of the product classified into the department code “1” and the product classified into the department code “2” is performed, the number is entered. Assume that an error has occurred due to an erroneous operation of pressing the department key 22. In this case, in the receipt printing example shown in FIG. 12, the header data 81 and the detailed data 82 of the registered product are already printed on the first receipt 80.

  Here, if the cashier presses the error explanation request key 28, the error description data for the no-number error is displayed in the receipt 80, “Please cancel the error with the C key. "Please press." 83 is printed, followed by footer data 84 excluding the transaction number. Further, at the same time when the next receipt 90 is printed on the receipt header data 91, the receipt 80 and the receipt 90 are cut by the cutting line 85, and the receipt 80 is issued from the receipt issuing port 7 as an error explanation receipt.

  Subsequently, the detailed data 92 of the registered product held in the print data buffer 33 is printed again on the receipt 90. After that, an operation for resolving the error state is executed and recovery is performed. After the registration of the product classified as the department code “3” is completed, when the closing operation is performed, the receipt 90 includes the remaining transactions. The detail data 93 is printed, the footer data 94 and the header data 101 of the next receipt 100 are printed, the receipt paper is cut along the cutting line 95, and the receipt 90 is issued as a purchase detail receipt.

  As described above, according to the present embodiment, even with a sequential printing type cash register that has only a small display, the cause of occurrence and the subsequent treatment procedure can be quickly determined by a simple operation when an error occurs. The operator can confirm. In addition, the receipt printed with the data of the product that was input before the error occurred is used as the error explanation receipt 80. After the error explanation receipt 80 is issued, the printed contents of the receipt are restored to the state before the error occurred. Therefore, it is not necessary to redo the merchandise sales transaction in which an error has occurred.

  By the way, some cash registers have a type in which a transaction number is printed as header data. In this type of cash register, the transaction number cannot be printed on the error explanation receipt 80. Therefore, for this type of cash register, the transaction number of the header data printed on the receipt next to the error explanation receipt is set to the same value as the transaction number printed on the header data of the error explanation receipt.

  That is, as shown in FIG. 13, the error explanation receipt 120 is printed and issued following the purchase details receipt 110 on which the header data 111 including the transaction number “1234”, the transaction details data 112, and the footer data 113 are printed. In this case, header data 121 including transaction number “1235”, transaction details data 122, error explanation data 123, and footer data 124 are printed on this error explanation receipt 120. Here, the transaction number “1235” is counted up when a transaction receipt (purchase details receipt 110) of the transaction number “1234” established immediately before is issued and printed as header data of the next receipt.

  Accordingly, when the error explanation receipt 120 is issued, the header data 131 for the next receipt 130 is printed. At this time, in the present embodiment, the transaction number “ The header data 131 including “1235” is printed. By doing so, the transaction number of the header data printed on the next receipt 130 of the error explanation receipt 120 can be set to the same value as the transaction number printed on the header data of the error explanation receipt 120. As a result, since the transaction number of the established transaction can be set as a serial number, the management of the transaction is facilitated.

  Note that the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the spirit of the invention in the implementation stage.

  For example, although the error explanation request key 28 is provided on the keyboard 2 in the above-described embodiment, the error explanation request key 28 is provided on a portion other than the keyboard, for example, a blind spot from the back side where the customer stands. You may not be enlightened.

In the above embodiment, the error explanation data is printed on both the receipt and the journal, but may be printed only on the receipt.
In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, the constituent elements over different embodiments may be combined.
