Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an electronic scale in which a card on which a person in charge or a customer's number is set is read by a card reader and cumulative processing is performed.

(Prior art) In large stores, etc., multiple electronic scales are connected to each other by pass lines as shown in FIG.
The product prices are accumulated for each store clerk or customer, and when the customer makes payment, the cumulative price for the same clerk or customer is calculated using an arbitrary electronic scale, and the calculation result is printed on the label or receipt. A weighing system is used.

(Problems with the conventional technology) In such a weighing system, each time a person weighs or sells a product, the person in charge selects his or her own person number key from among the plurality of person number keys installed and presses the key. I needed to. For this reason, (1) key operation errors are likely to occur, such as (1) erroneously turning on another clerk's staff number key during busy periods such as high customer periods;

(2) Even when the person in charge number key (person in charge number) is changed, key operation errors are likely to occur.

(3) In a store with many people in charge, a large number of number keys are required, which has the drawback of increasing the size of the key personnel department.

(4) When there are a large number of person number keys, it takes time to search for one's person number key, and key operation errors are likely to occur.

There were other problems. If a key operation error occurs, an incorrect payment result will be calculated, resulting in trouble with the customer.
There was a risk that this would develop into a problem that would affect the store's credibility.

(Object of the Invention) The present invention allows the person in charge number or customer number to be easily and accurately set by setting the person's number or customer number using a card and reading it with a card reader. The purpose is to provide an electronic scale that allows input.

(Summary of the Invention) The electronic scale of the present invention is equipped with a card on which a card number corresponding to a person in charge number or a customer number is set in advance, and a card reader that reads the card number of the card. The present invention is characterized in that it is provided with means for calculating and summing the calculation results for each read card number.

The above card also serves as a name tag for the person in charge.

Further, the card number is set by passing through a predetermined hole among a plurality of holes formed on one surface of the board.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 2 is an explanatory diagram of a card according to the present invention. Figure 2 (a
) is a card with no assigned personnel number, and in addition to the check pit that passes through the holes, the 1st, 6th, and parity pit holes are formed on one side of the card. A fixing hole is formed to fix the card when inserted. In Figure 2 (b), the name of the person in charge (△, X) and the number are written, and the binary code corresponding to the number is written. This is an example of a card set for hole penetration/non-penetration.This card can also be used as the name tag of the person in charge, and since the number is 18 and odd parity, it can be used for parity pits, 2nd bits, and 5th pin holes. is penetrated.

FIG. 3 is an explanatory diagram of the relationship between a card and a card reader that reads a card to which a 411 person number has been set. As shown in Figures (a) and (b), the card reader is equipped with a pole that is pressed by a spring near the card insertion slot, and when the card is inserted, the pole and the fixing hole are connected. When engaged, the card is fixed. A light emitting diode and a photo-luminescence diode are provided on the upper and lower surfaces of the card reader corresponding to each hole of the card, and when a card is inserted as shown in FIG. That is, the binary code corresponding to the person-in-charge number is read by the reception/non-reception of light.

FIG. 4 is a circuit diagram for reading the person-in-charge number set on the card. A three-state buffer is connected to each phototransistor provided facing the light emitting diode. A read signal is sent to the arithmetic control section from the output side of this buffer, and a read command signal from the arithmetic control section is also input. The functions of the calculation control section will be described later.

FIG. 1 is a schematic block diagram of an electronic scale of the present invention.

In the figure, the weight of the product detected by weight detection part A is
The signal is converted into a digital value by an A/D converter B, and is input to an arithmetic control section C composed of a microcomputer or the like. In addition, the user inputs the call number of the weighed product using the numeric keypad of the manual key section E, and reads out the unit price, product name code, etc. of the weighed product stored in a predetermined memory in the storage section to the arithmetic control section. After checking that the person in charge card J has been inserted into the card reader, the calculation control section calculates the price of the product. The display section G displays the unit price, weight, price, etc. of the product. Further, when the addition key of the key manual section is turned on, the card number-by-card number addition in progress display lamp F corresponding to the card number is turned on. Next, the product name, unit price, etc. of the weighed product are printed on the label or receipt by the printer H, and the price is added and stored in the cumulative price area corresponding to the card number in the cumulative total memory for each card number, and the cumulative number of products increases by +1. be done. At the time of payment, the contents of the cumulative memory by card number are sent to the electronic scale that processes the payment, and the cumulative price is calculated.
The customer settles the payment accordingly.

FIG. 5 is a flowchart 1. showing the processing procedure of the present invention. Next, this flowchart will be explained.

(1) Turn on the power switch to start the program (step P1), and display a message instructing to insert the card on the weight and unit price display in display section G (step P2). At this time, the price display in the display section G is left blank. Next, a read command signal is output to the card reader, and a read signal output from the phototransistor is input (step P5). Next, the presence or absence of the card insertion is checked based on the reading signal (step P4).
. If the card is not inserted, you will not be able to proceed to the following process.
Confirm that the card is inserted and perform the weighing process. (2) If the card is inserted, the reading signal (
Check the odd parity check according to the read data).Step P5) If the result of the parity check is correct,
The read data, that is, the card number, is displayed on the price display for a predetermined period of time, for example, 5 seconds (step 2). next,
Enter the call number using the numeric keypad and read out and set the unit price, product name character code, etc. stored in a predetermined area of the memory. The read unit price is displayed on the unit price display.

(3) Calculate the product and calculate the price (Step 2 days)
. Next, turn on the addition key of the function keys (step P9). The card number-specific addition in progress display lamp corresponding to the card number is turned on, and the card number-based addition in progress display lamps of all other electronic scales corresponding to this card number are turned on (step Pro). Next, print the name, unit price, weight, price, etc. of the weighed product on the label (
Step P]1).

(4) Add and store the printed price to the cumulative price of this card number in the cumulative total memory by card number, and add 1 to the cumulative number of products (step P12). Next, the card number, weight, price, etc. are sent to the totaling machine (step P13). The aggregation machine performs aggregation by product category, card number, time of day, etc.

(5) Output a reading command signal to the card reader and input the reading signal (step P14). Next, after weighing and label printing, a read signal is used to check whether a card has been inserted to check whether the card has been removed or not (step P15). or issue subtotal labels. If there is no card, this means that the card has been removed after weighing and printing with this card number has been completed, and the process returns to step P2.

FIG. 6 is a flowchart showing a processing procedure when a certain electronic scale issues a subtotal label (settlement label) for settlement. Next, this flowchart will be explained.

(1) With card J inserted into card reader I, turn on the subtotal key of the function keys (Step S1)
, clear the subtotal memory to zero (step 32). Next, the cumulative price and the cumulative number of products for this card number are read out from the cumulative total memory for each card number of this electronic scale and stored in the subtotal memory (Step S3), and the cumulative total for this card number is stored in the cumulative total memory for each card number that has been read out. Clear the price and the cumulative number of products to zero (step 54) - (2) Thereafter, the cumulative price and cumulative number of products corresponding to this card number are sequentially retrieved from other electronic scales and added to the subtotal memory and stored (step S5) Next, the contents of the subtotal memory (total price and total number of products for this card number) are printed on a label (step 8). Subsequently, the contents of the subtotal memory are transmitted to the aggregation machine (step S7), and the card number-by-card number addition in progress display lamp corresponding to this card number is turned off (step Ss). In the electronic scale called in step S5, after transmitting the cumulative price and the cumulative number of products to the electronic scale, its memory is cleared to zero, and the card number-specific addition in progress display lamp is turned off.

Figure $7 is an explanatory diagram of the receipt 1 and the label printed by the printer. FIG. 4A shows a case where the printer H is a receipt printer, and the price of each product is totaled, and the card number and cumulative price are printed at the end. In addition, in the same figure (b), printer H is an example of a label printer, and labels (A) to (E) are printed for each product on each electronic scale that weighs the product. The label (to) is printed.

The following explanation is an example using multiple electronic scales, but 1.
The present invention can also be implemented in an electronic scale with an independent stand. In other words, in order to aggregate the sales amount etc. for each person in charge,
Electronic scales were used that had the function of counting numbers by person in charge, but since the 111 person number was entered using a numeric keypad, key operation errors could occur, and it was not possible to input the person number using a card. By inputting the information, key operation errors can be prevented.

Further, the card and the card reader are as follows: (1) A magnet is buried in the hole of the card, and the card reader is provided with means for detecting magnetic force using a Hall element or the like to read the number.

(2) Use a magnetic card and magnetic detection head.

It can also be composed of

Furthermore, the usage of the card is as follows: (1) One person in charge follows each customer with the card and performs weighing on each electronic scale, calculating prices, printing on a printer, etc. Let's do it.

(2) Hand the card to the customer at the entrance of the store, and the person in charge will receive the card when weighing and checking. In this case, there is no need for the same person in charge to follow one customer.

It can be implemented as follows.

(Effects of the Invention) As explained above, the present invention uses a card and a card reader to input the person in charge or customer number. (1) There is no need to search for the key number, and regardless of the number of persons in charge First, there will be no mistakes in entering the person in charge or customer number.

(2) Even if the person in charge number changes, input errors can be prevented by changing the card or creating a new card.

(3) Even if the number of people in charge increases, the size of the card and card reader will not increase, so the space of the entire device will not increase.

Effects such as this can be obtained.
