Description

[Detailed Description of the Invention] Conventionally, when weighing items with different unit prices, price scales have had to set the unit price for each item, making the operation complicated, and in some cases, setting the unit price. It could also lead to mistakes.

Furthermore, it was not possible to keep any records of measurements.

The present invention aims to eliminate this complicated operation as much as possible by storing unit prices for multiple types of items that usually sell well in advance, and inputting the code of the item to be weighed.
The unit price of the item is extracted and the unit price is automatically set, and the amount is accumulated for each item weighed.
The purpose is to provide a scale that can calculate and aggregate the daily sales amount and the monthly sales amount for each product name and type.

The details will be explained with reference to an embodiment shown in the accompanying drawings.

Reference numeral 1 designates a first unit price storage section in which a plurality of types of unit prices are stored. On the input side of this unit price storage section 1, there is a readout selection switch 2 for selecting each condition for reading and reading unit prices, and a readout selection switch 2 for selecting unit price settings. It is equipped with an input device 3, an input device 4 for setting the product type, and an input device 5 for setting the product name.To store unit price settings, set the selection switch 2 to the reading side and set the unit price. The unit price value is inputted from the input device 3, the type code is inputted from the type setting input device 5, and the product name code is inputted from the product name setting input device 4.

Incidentally, each input to each of the input devices 3, 4, and 5 is performed by pressing a button on a numeric keypad switch.

Further, the output side of the l-th unit price storage section 1 is connected to one input terminal of an AND gate 6, and when the unit price storage section selection switch 7 connected to the other input terminal of the AND gate 6 is turned on, the output side of the l-th unit price storage section 1 is stored. A circuit is constructed in which the output signal of the section 1 is inputted to an arithmetic circuit 9 and a unit price display circuit 10 through an AND gate 6 and an OR gate 8.

The above explanation has been made regarding the first unit price storage section 1 in which multiple types of unit prices are set, but even for items that are not stored in this unit price storage section 1, it is necessary to set the unit price for one item name as in the conventional method. Because of the relationship that may occur, a second unit price storage section 11 is provided at a branch of the circuit from the unit price setting input device 3, and the value set in the unit price setting input device 3 is stored every time. It has become.

This second unit price storage section 11 stores only the unit price of the item, and when the next unit price is input, the previous unit price is cleared.

Further, the output side of the second unit price storage section 11 is inputted to one terminal of the AND gate 12, and passes through the OR gate 8 in coincidence with the signal via the inverter 13 connected to the other terminal of the AND gate 12. Similarly to the output from the first unit price storage section 1, the calculation circuit 9 and the unit price display circuit 1
It will be input as 0.

Note that the output selection of the first unit price storage section 1 and the second unit price storage section 11 is performed by turning on the unit price storage section selection switch 7,
Determined by off operation.

That is, by turning on the switch 7, the first unit price storage section 1 is selected, and by turning it off, the second unit price storage section 11 is selected.

The arithmetic circuit 9 calculates the amount by multiplying the input unit price by the weight signal α output from the load converter (not shown), and the output signal of the amount is input to the next amount display circuit 14. The amount will be displayed.

By the way, the above-mentioned "varieties" refer to, for example, fruits, fish, meat, wild-pot cooking, etc., and "item names" refer to each individual item of the variety, such as mandarin oranges, rinko, sardines, mackerel, pork, etc. This indicates average quality beef, radish, carrots, etc.

Further, the "subtotal variety" indicates, for example, the daily sales of fish, and the "total variety" indicates, for example, the monthly sales of fish.

Next, the "product name subtotal" indicates, for example, the daily sales of sardines, and the "product name total" indicates, for example, the monthly sales of sardines.

Reference numeral 15 denotes a selection circuit which selects each memory section for accumulating the price of the product type and product name based on the product type and product name signal P1 (code signal) outputted from the first unit price storage section 1, and 16 the selected memory section. This is an addition circuit that adds the contents of the section and the value B of the amount just calculated.

Reference numeral 17 designates a selection circuit for a storage section that stores the contents added by the addition circuit 16, 21 a storage section for product name subtotal, 20 a storage section for product name total, 19 a storage section for product subtotal, and 18 a storage section for product total. Department.

22 is a selection circuit for each display content, 33 is a switch for total subtotal calculation, and 32 is a switch for total calculation.

Each of the storage units 1B, 19, 20.21 has a number of storage units corresponding to the number of types and product names.

Reference numeral 25 is an addition circuit that adds up the sum of each product type, and reference numeral 23 is a storage section that stores the amount summed up by the addition circuit 25.

The present invention has the above structure, and its operation will be explained next.

First, to set the unit price, product type, and product name for multiple items, set the readout selection switch 2 to the read side, input the unit price into the unit price setting input device 3, and set the product type and product name for each unit price. By inputting the code from the input devices 4 and 5 for setting the product type and product name, respectively, the unit price is input into the first storage unit 1 in pairs with the product name of the product type.

It should be noted that this storage is sequentially input to required addresses in the storage section 1.

Repeat the above operations to store the required number of unit prices in advance.

Next, the operation of calculation of measurement and charge, display thereof, and cumulative total will be explained. Select and set the code of the item to be weighed in the memory section of the item name, and each input section 4 for setting the product type or item name.
.
At the same time, the product type and product name codes are given to selection circuits 15 and 17.

Accordingly, the unit price is displayed by the unit price display circuit 10 based on the signal, and the amount B is obtained by multiplying the weight signal α output from the load converter by the unit price by the arithmetic circuit 9.

Further, the amount B will be displayed on the amount display circuit 14 at the next stage.

By obtaining the amount B as described above, the amount B is inputted to the selection circuit 15, and is passed through the selection circuit 15 by the code signal P1 outputted from the unit price storage circuit 1.
The address of each storage section of the product type and product name corresponding to the code is selected, the content of the number and the amount B that has just been calculated are added in the circuit 16, and the addition result is again sent through the selection circuit 17.
