Description

[Detailed description of the invention]

The present invention relates to a fee calculation system that outputs price information of an object to be weighed calculated from a weighed value and a set unit price, and particularly relates to a system configured to print and issue the price information on a label or receipt. The purpose of this is to improve processing capacity and provide a device that can be made smaller. First, the sales format targeted by the fee calculation scale and its peculiarities will be explained in comparison with a sales format such as a supermarket. In supermarkets, customers bring their purchased products in bulk to a checkout terminal, so cashiers are unable to continuously input price information of sold products into a checking device, such as a cash register, without any lag. The normal receipt issuing operation (payment total printing operation) in which a plurality of pieces of sales price information for one customer are printed on a series of receipts does not greatly affect the processing capacity of the checking device. However, in face-to-face sales of scale-sold products that are processed by the above-mentioned fee calculation scale, when one customer purchases multiple items, the customer often considers the purchase amount etc. Therefore, in the above-mentioned receipt issuing operation, even though there is a waiting time for the fee calculation scale during the processing [between weighing], one customer is not charged until one customer finishes shopping. The current situation is that they are forced to use it exclusively for customers. Further, as a device that allows two customers to conduct transactions at the same time, it is conceivable to provide two sets of function keys that are involved in the registration function, closing function, and correction function. However, in this case, the number of keys becomes considerably large, which not only increases cost but also occupies a large area of the operation panel, so it is not easy to implement. Next, a fee calculation scale according to the present invention that can avoid the above-mentioned problems will be described based on an embodiment. 1 is a charge calculation scale body that outputs price information (DM) of the object to be weighed calculated from the weighed value and unit price, a unit price setting section where the price of the object to be weighed per unit weight is set, and a unit price setting section where the price of the object to be weighed per unit weight is set, and a load value A weighing section configured to convert the weighing information into a digital signal and, for example, output a balance signal B which monitors the weighing information and detects a balance state of the weighed value; and a price calculation section that calculates a price from the weight information and the unit price information from the unit price setting section. 2 is a total register which, when the first registration instruction switch _SW1 is operated in a state where the weight values are balanced, accumulates and stores the price information DM at that time. Reference numeral 3 denotes a buffer register, which includes a register _3a that sequentially stores the price information at that time when the second registration instruction switch SW 2 is operated in a state where the weighed value is balanced, and an AND gate 4.
a counter 3b that counts the number of times the second registration instruction switch SW ₂ is operated via a register 3;
and a register 3c that cumulatively stores the price information Da each time it is stored in the register 3c. Reference numeral 5 denotes a gate circuit interposed at the data input of the total register 2, which is controlled by a control section 6 to be described later, and switches the data to the total register 2 into the price information Da and the contents stored in the register 3c. 6 is the first and second
The control section serving as a printing control section detects, via the AND gate 7 in the same way as the total register 2, that the first printing instruction switch SW ₁ is operated in a state where the weighed value is balanced, and prints the price information. Instructs the subsequent printing device 8 to print Da, and also closes the tightening instruction switch.
It detects the operation of SW ₃ and instructs the printing device 8 to print the stored contents of the total register 2, and also outputs a clear signal I to automatically clear the contents of the total register 2. When the total amount of the stored contents is monitored and it is detected that the total amount is at the cleared amount "zero", a gate switching signal and a storage instruction signal are output to the gate 5 and the total register 2, respectively, and at the same time the counter The printing device 8 is configured to instruct the printing device 8 to print all the price information accumulated in the register 3a based on the count value of the register 3b, and output a clear signal to automatically clear the registers 3a and 3c. has been done. The actual device is further equipped with a display device that digitally displays other weighing values, set unit prices, calculated price information, and total amount, but since this is not related to the gist of the present invention, FIG. It is omitted from. Next, the configuration of the control section 6 will be explained in detail. Here, a case where price information Da for another customer F is processed during a receipt issuing operation for customer E will be described as an example. If the weighing order and amount of shopping for customers E and F are as shown in the table below,

[Table] At the first measurement, the first registration instruction switch
SW ₁ is operated, the printing device 8 is instructed to receive 500 [yen] as the price information Da via the control unit 6, 500 [yen] is printed on the receipt, and the total register 2
stores Σ ^M =500 yen via the gate circuit 5.
At the second weighing, since it is for customer E as in the first weighing, the first registration instruction switch _SW1 is operated again. As a result, the printing device 8 prints the 500 [yen] on the receipt, and then
200 [yen] is printed, and the contents of total register 2 Σ _M
= updated to 700 [yen]. Since the third weighing is not for customer E who is in the process of printing a receipt, the second registration instruction switch SW ₂ is operated to store it in the buffer register 3. Due to this operation, the printing device 8 does not perform any printing operation, and the contents of the registers 3a and 3c are both 100 [yen].
The count value of the counter 3b is incremented to "1". Also, since the fourth weighing is for customer E who is in the process of printing a receipt, he operates the first registration instruction switch SW ₁ , prints 300 [yen] on the printing device 8, and also prints 300 [yen] on the total register 2.
The memory content of is updated to Σ _M = 1000 [yen] [(500 + 200) + 300]. In the fifth time, since it belongs to customer F, operate the second registration instruction switch SW ₂ ,
Store it in buffer register 3, update the contents of register 3a to 100 [yen] and 400 [yen], update the contents of register 3c to 500 yen [100 + 400], and count up the count value of counter 3b to "2". do. When customer E operates the tightening instruction switch SW ₃ after the completion of the fifth weighing, the printing device 8 prints out the contents Σ _M of the total register 2 according to the instructions from the control unit 6 as 500 yen and 200 yen. Then, a subtotal of 1000 [yen] is printed on a series of receipts with 300 yen printed on them, and a receipt is issued. Additionally, since the contents of the total register 2 are automatically cleared in conjunction with this, the control unit 6 clears the buffer register 3 through the process shown in FIG.
The printout of the register 3a and the contents of the register 3c are transferred to the total register 2. That is, when it is detected that the memory content of the total register 2 has been cleared to the total amount "zero" [a-1], it is confirmed that the content _Σs of the register 3c is not "zero" [a-2] and the gate circuit is activated. 5 and transfer the memory contents of register 3c to total register 2 [a
-3], the printing device 8 prints out the 100 [yen] that was initially stored in the register 3a [a-4], and the control unit 6 detects the printing end instruction signal of the printing device 8 [a-5]. ] and outputs a down count signal to the counter 3b and changes the count value N to "1" [a-
6], and then checks [a-7] whether the count value of the counter 3b is zero. Here, since the count value is "1", a shift pulse is sent to the register 3a [a-8], and it returns to [a-4] again, and the printing device 8 is controlled to print 400 [yen] of the output of the register 3a. Similarly, the counter 3b receives a down count signal and the count value becomes "zero", so a match is detected at [a-7] and the contents of the register 3a are cleared, for example. If customer F continues shopping after that, as in the case of customer E,
By operating the first registration instruction switch SW ₁ , the price information at that time can be printed on a series of receipts on which the third and fifth price information are printed, and the contents of the register 3c can be printed. Total register 2
Therefore, the tightening for customer F can be obtained by operating the same tightening instruction switch SW ₃ as for customer E. In this way, the price information of another customer F while printing a receipt for one customer E is stored in the buffer register 3, and the contents of the buffer register 3 are automatically printed after the receipt issuing operation for customer E is completed. Due to this configuration, one printing device 8 can process two customers E and F. In the above embodiment, the gate circuit 5 is switched after checking the contents of the register 3c [a-2], but the same effect can be achieved even if the switching is performed after confirming that the count value of the counter 3b is not zero. 2], it is also conceivable to switch to the register 3c side. In the above embodiment, the control unit 6 is the total register 2
The control unit 6 is configured to automatically print out the information stored in the buffer register 3 when the contents of the total register 2 are in a clear state or have been cleared. It is also possible to print out the information in the buffer register 3 only after detecting a subsequent printing operation. Note that the printing operations here include operating the first or second registration instruction switch, operating the tightening instruction switch, and in the configuration diagram of FIG. 1, using only the registration mode as an example. Examples include operation of a correction instruction switch (including a subtraction instruction switch), which is used when correction of information occurs, or operation of a subtotal print instruction switch, which instructs printing of the total amount. As an example of the control section 6 in this case, FIG. 3a shows a case where the operation of the first registration instruction switch SW ₁ is detected and the contents of the buffer register 3 are printed out, and FIG. A flowchart is shown when detecting the operation of the registration instruction switch SW ₂ and printing out the contents of the buffer register 3. In this case, if the content Σ _M of the total register 2 is the total amount "zero" yen and the information is stored in the buffer register 3, the first or second
The price information DM output from the toll scale body 1 at the time when the registration instruction switches SW ₁ and SW ₂ are operated is
The past price information is printed out at the end of the receipt following the printout of past price information stored in the buffer register 3 up to that point. In Figure 3 a and b, [a-1] [a-
2], [a-4] to [a-9] represent the same steps as in FIG. In addition, in each of the above embodiments, the buffer register 3
In the above, the cumulative value of the information stored in the register 3a is stored in the register 3c, but this means that when the contents of the register 3a are sequentially printed out, the price information is sequentially accumulated in the total register 2 and the total value is stored in the register 3c. You can also get information about the amount. As described above, according to the present invention, the charge calculation scale body includes a total register for storing cumulative price information at the time of operation of the first registration instruction switch; Instructs a downstream printing device to print out the information, detects the operation of a tightening instruction switch, and instructs the printing device to print the stored contents of the total register, and automatically prints the stored contents of the total register up to that point. a first print control section that clears the operation price information of the second registration instruction switch; a buffer register that can store price information; A second print control unit is provided that instructs the printing device to print the contents of the buffer register when a printing operation is detected, so that even though there is only one printing device, multiple users It is necessary to be able to process customers, improve processing capacity, and downsize the equipment, and in particular to make effective use of limited space such as on the top of the show case. Effective in price calculation scales for face-to-face sales.
