Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is directed to an electronic cash register that can automatically correct the date printed on a receipt when the date has changed.

[Prior Art] As is well known, the procedure for registering a product sold to one customer at an electronic cash register installed in a store is as follows.
Sales price and number of sales items for each product.

Enter the department code one by one manually using the registration keys on the keyboard. Then, as shown in FIG. 8, the sales data of the product, including the department code 2 and the sales amount 3, are sequentially printed out on the receipt 1. Then, when the single item registration operation for all sales items is completed and the total key is operated, the total amount 4 is printed out on the receipt 1. Receipt 1 is then fed and ejected from the receipt issuing port.

If there is a deposit amount, the deposit amount and change are also printed on the receipt 1 as shown in the figure.

Generally, in an electronic cash register that issues such a receipt 1, a stamp device is disposed between the print head position of the printer of the receipt 1 and the cutter position that cuts the receipt. The cutter cannot be placed close to the cutter. Therefore, in response to the key operation of the total key, after printing the total amount 4, the paper is fed by ΔL as shown in FIG. Stamp characters 5 such as , etc. are printed as a stamp, and the current date 6 is further read out from the clock circuit and printed. Then, the receipt 1 is cut with a cutter at the position of the broken line 31 in front of the stamp 5. The user then enters sales data for the product sold to the next customer. By printing out the date 6 in advance on the receipt 1a to be issued to the next customer in this way, it becomes possible to use the receipt paper effectively.

[Problems to be Solved by the Invention] However, even in electronic cash registers in which the date 6 is printed out in advance at the top of the next customer's receipt 1a as described above, the following similar layer exists. That is, even at the end of the day's work, the date 6 is still printed on the receipt 1 to be issued to the next customer.

In this state, the date changes, and when the store opens the next morning and performs the sales registration operation for the first customer, a receipt 1 with the previous day's date 6 printed on the top will be issued to this customer. become. Therefore, the cashier had to manually correct the date 6 on the receipt 1 only for the first customer.

This correction is troublesome, and if the correction is forgotten, there is a concern that trouble will occur when determining the sale date at the time of return.

The present invention provides an electronic cash register that can always issue receipts with the correct date and improve reliability by constantly storing the printed date in a date memory and checking the date when the power is turned on. purpose.

[Means for Solving the Problems] As shown in FIG. In an electronic cash register that issues a receipt C on which the total amount is printed out to a customer and also prints out the date read from the clock circuit a on the receipt for the next customer, a date memory d that stores the printed date; In response to the power-on operation e, the clock circuit a
date judgment means f which judges whether or not the date of the date matches the date of the date memory d, and when this date judgment means f judges that the dates do not match, the receipt C is paper-fed and then the clock circuit a
date correction means 9 for printing out the date.

[Function] With an electronic cash register configured in this way, when the closing key is pressed after completing the registration of each product sold to -1 customers, the total amount will be printed on the receipt and the next item will be displayed. The current date of the clock circuit is printed out on the receipt, and this date is stored in the date memory. Then, for example, if the power is turned on before the start of business the next day, the date in the clock circuit and the date in the date memory will not match, so the part of the receipt where the date of the previous day is printed will be fed and read from the clock circuit anew. The current date will be printed. In other words, the correct date is always printed on the receipt handed to the customer.

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

FIG. 2 is a block diagram showing a schematic configuration of the electronic cash register of the embodiment. That is, the CPU (central processing unit) 11 has a built-in arithmetic circuit, etc., and performs various arithmetic processing based on input information from the keyboard 12 on which keys for various sales registrations are arranged.
．． Data bus 14. A ROM 16 that stores fixed data such as each business program via a system 111115, and a RAM 17 that stores sales data such as the sales amount of each product that is constantly stored by a battery and manually input are operated. Further, a control key input circuit 19 receives command signals from a control key 18 for selecting and setting various business modes such as [registration], [inspection], [accounting], and [setting].
A keyboard input circuit 201 receives key signals from the keyboard 12, which is provided with various registration keys such as number keys, department keys, deposit/account keys as closing keys, etc. Department codes, sales amounts, total amounts, etc. Display unit 21 that displays electric light
A display control circuit 22 for sending out display signals to a printer, a printer control circuit 24 for a dot printer 23 that prints out various data on a receipt, and a clock circuit 24 that is constantly supplied with driving voltage by a battery and that measures the current date (month, day) Do. data bus 14. CPtJll via control line 15
It is connected to the.

In addition to the dot printer 23, the printer control circuit 24 also drives a stamp mechanism 26 that prints fixed stamp characters 5 such as a store name and telephone number on the receipt 1, and a cutter 25 that cuts the receipt 1.

As shown in FIG. 3, the RAM 17 stores, for example, sales data such as the department code, number of sales items, and sales amount of each product for sale, entered manually using the stroke number keys and department keys of the keyboard 12, for example, by department code. Sales registration file R1
, a totalizer R2 that calculates the total price of products sold to one customer, a display buffer R3 that temporarily stores display data to be displayed on the display unit 21, and a print buffer R4 that temporarily stores print data that is printed out on the receipt 1. , a print date buffer R5 that stores the print date Ds to be printed out on receipt 1.
, a date memory R6 for storing a printed date D2 printed on the receipt 1, etc. are formed.

For example, when the electronic cash register is powered on at the start of a day's work, the CPU 11
The program is configured to carry out the flow chart shown in the figure. That is, when the power switch is turned on, a series of initial processing including initialization of each input circuit 19.20 and each control circuit 22.24 is executed, and then the current date and time Do is read from the clock circuit 25 and the printed date is returned. Store in 7R5.

After that, the printed date D is updated to the current date Da at Pl.
1 and the printed date D2 of the date memory R6. Both dates D1. If D2 do not match, the printing date Ds is stored in the date memory R6. That is, at this point, the date D2 in the date memory R6 becomes the current date (D2-DI-D
o).

After that, as shown in FIG. 7, after paper feeding the receipt 1 by the width ΔL of the stamp character 5 and date 6, the printing date D1 (6a) of the printing date buffer R5 is printed out, and then the stamping mechanism At step 26, the stamp characters 5a are printed. Then, the receipt 1 is cut at a position above the stamp character 5a indicated by the broken line 31. And yesterday's date 6
The receipt 1 on which only the stamp characters 5 and 5 are printed is discharged from the receipt issuing port. Thereafter, the print date buffer R5 is cleared at P2.

In addition, the print date DI of the print date buffer R5 is set at Pl.
If the printed date D2 of the date memory R6 matches, it is determined that the power was once cut off and then turned on again on the same day. In this case, the printed date D2 of date memory R6
Since is the current date Do, the process directly advances to P2 and clears the print date buffer R5.

After the electronic cash register starts to operate normally after the N power is turned on, a single item registration operation is performed in which sales data such as the sales amount, number of items sold, and department code of the products sold to the customer are entered manually from the keyboard 12. , the CPU 11 executes the single item registration process according to the flowchart in FIG.

That is, when sales data of a sales product is input, the sales data is displayed on the display section 21 and the sales registration file R is displayed.
1, and the sales amount is added to totalizer R2. Then, as shown in FIG. 8, the department code 2 and sales amount 3 are printed out on the receipt 1. Then, receipt 1 is fed by one line.

When the single item registration operation for all products sold to one customer is completed and the closing key such as the deposit/cash key is pressed manually,
The closing key process shown in FIG. 6 is executed.

When the flowchart is started, the total amount 4 of the totalizer R2 is displayed on the display section 21, and as shown in FIG. 8, it is printed out on the receipt 1, and the total amount of the totalizer R2 is cleared. If the deposit amount is entered, change etc. will be calculated, displayed and printed.

After that, the receipt is paper-fed by 61 minutes. Then, the current date Do is read from the clock circuit 25 and stored in the print date buffer R5.

At R3, the printed date D1 in the printed date buffer R5 is compared with the printed date D2 in the date memory R6.

If they match, the printing date D1 in the printing date buffer R5 is printed out on the receipt 1 as is in R4.

If they do not match, print date D1 in print date buffer R5
is stored in the date memory R6, and then the print date buffer R
5 is printed out on receipt 1.

When the date 6 (-01) is printed on the receipt 1 at R4, the stamp mechanism 26 prints stamp characters 5. Thereafter, the receipt 1 is cut at the broken line 31 between the total amount 4 and the stamp characters 5, and is discharged from the receipt issuing port. After that, the print date buffer R5 is cleared. This completes the series of sales registration processing for one customer.

Even if the electronic cash register is configured in this way,
- When the registration operation for each product sold to a customer is completed and the deposit/total key is pressed, the current date Ds read from the clock circuit 25 is printed on the receipt 1 via the print date buffer R5. At the same time, it is stored in the date memory R6 as the printed date D2. That is, the date printed on the receipt 1 issued to the regular customer is stored in the date memory R6.

Then, when the electronic cash register is powered on the next day, etc., the date memory R6 is
The printed date D2, that is, the date 6 printed on the receipt 1 at this point, is the current date Do of the clock circuit 25.
If they do not match, the receipt 1 is advanced by Δ and the current date and time Do is newly printed via the printing date buffer R5. The receipt 1 on which the previous day's date is printed is then cut by a cutter 27 and discharged from the receipt issuing port. Therefore, receipt 1 issued to a new customer
is the current date 6. (-Do) is printed.

In this way, for example, the date on the receipt is automatically updated before the start of the day's work, which reduces the burden on the cashier and also prevents unnecessary trouble with customers regarding the sales date when returning goods. can be prevented from occurring.

In addition, the closing keys such as the deposit/cash total key have the function of the final execution command key in the [settlement] process that is performed after the end of the day's business, in addition to the closing key processing during the normal sales registration work described above. Therefore, even at that point, a series of stamp characters 5 and a date 6 are printed on the receipt 1. Therefore, the date printed on the receipt 1 is automatically updated even when the power is turned off the next morning after the execution of the [Select Bullet] task and the power is turned on the next morning.

[Effects of the Invention] As explained above, according to the electronic cash register of the present invention, the printed date is always stored in the date memory, and when the power is turned on, the date is compared with the current date, and if they do not match, I am trying to print the current date on the receipt. Therefore, it is possible to issue receipts with the most important dates at all times, and reliability can be greatly improved.
