Abstract

PURPOSE:To ensure the smooth shopping for customers by storing the counters in an electronic calculator after sorting them and displaying successively the stored data for each counter. CONSTITUTION:When a customer reads the data out of an electronic calculator at his/her actual shopping, the customer turns on a 'see' key of a key part 4 to set a read mode. In this read mode, one of plural counters stored in a RAM 9 of a display part 3 is displayed together with the total number of other remaining counters. The displayed counter is shifted every time a 'counter' key is turned on, and other counters stored in the RAM 9 are displayed successively with switching. Thus the customer can grasp the total counters before actually making purchases. Then the customers can accurately know the routes of plural counters in the supermarkets and the shopping districts even for the first time or despite the change of layout of the counters there.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention particularly relates to a shopping calculator that is used to accurately purchase various products in daily shopping for small items.

(Prior art) In general, when purchasing a wide variety of small-value items such as fresh foods and preserved foods that are consumed on a daily basis in daily life, it is difficult to memorize all of them before going shopping. It is easy to have an excess or shortage of food, which in turn makes it difficult to maintain a healthy household budget, so before going shopping,
Make a note of the products you want to purchase and their quantities in advance, and when you actually go shopping, check to make sure you have completed each purchase to make sure you don't forget to buy the products you planned on purchasing. is desirable.

By the way, it has been proposed to use a calculator with a memory function to take notes for such shopping. For example, in the method proposed in Japanese Unexamined Patent Publication No. 58-58670, the cumulative budget amount for multiple products to be purchased is manually recorded, and each time each product is purchased, the amount of expenditure is subtracted in order. If the total amount of expenditure exceeds the budgeted amount, a warning is issued to the purchaser to draw their attention.

(Problem to be solved by the invention) However, this conventional system only has the function of warning when the cumulative cost of purchased products exceeds the budget.
I can't categorize the product I'm trying to purchase. For this reason, for example, when purchasing multiple types of products on the same sales floor, after purchasing some of them, the remaining products may be on the same sales floor, but the customer may move to another sales floor and purchase another product. In this case, the user must return to the original sales floor to purchase the item that he/she forgot to buy, which becomes extremely troublesome. In particular, when it is necessary to visit many sales floors, the user has to go back and forth in large stores such as supermarkets and shopping streets, which requires a great deal of effort.

The present invention has been made in view of the above points, and its purpose is to classify various types of products to be purchased, store them in a calculator, and display them. The purpose is to allow customers to shop while smoothly visiting the stores without having to travel back and forth unnecessarily.

(Means for Solving the Problem) In order to achieve the above object, the solving means of the present invention is to classify a plurality of types of products and their quantities in advance into a calculator before going shopping. When the user goes shopping, the stored data is displayed in order for each department.

Specifically, as shown in FIG. 1, the configuration of the present invention includes display means 3 for displaying data, product name,
An input means 10 for inputting the quantity and sales floor; a storage means 9 for storing data on the product name and quantity entered by the input means 10 collectively for each sales floor; and the product name and quantity stored in the storage means 9. The present invention is characterized by comprising an output means 11 for displaying the data on the display means 3 for each sales floor.

(Function) With the above configuration, in the present invention, before going shopping,
In advance, the name of the product to be purchased, its quantity, and the sales floor are input using the input means 10.

This input data is stored in the storage means 9, with product names and quantities organized for each sales floor. Thereafter, when the user actually goes shopping and operates the output means 11, the stored item names and quantities are called up for each sales floor and displayed on the display means 3. In this way, the product name and quantity are displayed in order for each department, so buyers can recognize each department and
Next, it is possible to recognize all the products to be purchased at that sales floor. As a result, it is possible to move through each sales floor in order and reliably purchase products at each sales floor, eliminating the need to go back and forth between sales floors unnecessarily, and thus greatly reducing shopping effort.

(Example) Hereinafter, an example of the present invention will be described based on the drawings from FIG. 2 onwards.

The display section 3 is made up of a liquid crystal, a light emitting diode, etc., and includes, for example, "Uriμ?" (sales floor) and "Namako?" (product name).
, "Surariyou?" (Quantity), "Nedan?" (Price),
It constitutes a display means for displaying various data such as "Total amount" (total amount), "Remaining amount" (remaining number), and "Yosan" (budget).

Further, the key portion 4 is composed of a plurality of keys arranged in a matrix in the vertical and horizontal directions (note that the names of the keys shown in the drawing without reference numerals are used as they are with the quotation marks ""). Among these keys are alphabet keys (some of which double as numeric keys) for inputting/outputting data, and pressing each of these keys as they are will change the upper alphabet (for example, rK/IJ keys). "K"), but if you press each key after pressing the "Shift" key, the lower number, unit, etc. ("1") will be displayed.
are input respectively.

Further, the "input/budget" key is operated initially when data such as product names, quantities, sales locations, and budgets are input as stored data. The "↓" key is operated to switch input or output data. The "correct" key is operated to correct data. rYES/NOJ
The keys are operated to confirm input or output data.

The "start" key is operated before the "input/budget" key is operated when inputting data.

The "view" key is operated initially when outputting data such as product name, quantity, sales floor, budget, etc. as stored data. The "store" key is operated to output the store as data, and the "name" key is operated to output the product name as data.

The "Complete/Add" key is operated when the purchase of a product is completed, and when pressed twice or more, the mode is switched to additional purchase mode. The "yen/delete" key is operated when inputting the price of a purchased item, and
If you press it more than once, the mode will switch to return mode.

In addition, an "output" key is provided in some of the keys above, and by turning on this "output" key,
Data is exchanged between calculator A and an external computer.

As shown in FIG. 2, the display section 3 and key section 4 are connected to a CPU 7 via input/output interfaces 5 and 6, respectively, so that they can send and receive signals, and the CPU 7 has a ROM 8 and a RAM 9 that can send and receive signals. It is connected to the.

The procedures of various signal processing performed by the CPU 7 will be explained.

(1) First, when inputting data (store, product name, quantity) before going shopping, an input mode as shown in FIG. 3 is executed. This mode is started by inputting a push operation signal of the "start" key. First, after inputting the signal, it is determined in step S1 whether or not the "input/budget" key has been pushed (ON operation). , if this determination is No, step S1 is repeated. - On the other hand, if the determination is YES, the process proceeds to step S2, and the display section 31 displays "Uri style?". Then,
In step S3, it is determined whether or not "Sales Floor" is input by operating the alphabet keys and then the "↓" key is operated. If the determination is No here, the same step S2+83 is repeated, while YES is determined.
If it is determined that this is the case, the process proceeds to step S4, and the display section 3 displays "Name?". Furthermore, in step S5, it is determined whether or not the "product name" is input by operating the alphabet keys, and the "number" key is subsequently operated. If this determination is No, step S4. While repeating S5, if the determination is YES, in step S6, the display section 3 displays "Surariyo?". After that, in step S7, it is determined whether "quantity" is input by operating an alphabet key after operating the "shift" key, and whether or not the "↓" key is subsequently operated. If this determination is NO, it is determined. Step S6. While repeating S7, if the determination is YES, the process advances to step S8, and the display section 3
Displays all of the data entered above, ie, "store", "item name", and "quantity". Furthermore, in step S9, rYES is sent to determine whether the displayed data is correct or incorrect.
The number of times the /NOJ key has been operated is determined, and when the key has been operated once, the above data (sales floor, product name, and quantity) are stored in the RAM 9 in step SIO. On the other hand, rYES
/NOJ key is operated twice, step Sl
Press + to cancel all the data entered above. After steps SIO and SI+, the process returns to step S1, and subsequent steps S2+33+ are repeated to repeat the same procedure as above for the next product.

(a) Also, when inputting a shopping budget, as shown in FIG. 4, a budget input mode is executed that starts when the "input/budget" key is turned on two or more times. That is, In this mode, "Yeosan?" is displayed on the display section 3 in the first step S21.After this, in step S2
In 2, the purchaser uses the numeric keypad (alphabet keys)
``Budget'' is entered by the operation, and then ``↓''
Determine whether a key has been operated. If this determination is No, steps S2+ and S22 are repeated, and the determination is Y.
When ES is reached, the process proceeds to step S23, where the display section 3 displays "Yeosan oooo en", and further, step S2
In 1, [Y
The number of operations on the ES/NOJ key is determined, and when the key is operated once, the above data (budget) is displayed in step S25.
is stored in the RAM 9 and the process ends. On the other hand, rYES/N
When the OJ key is operated twice, the inputted budget data is canceled in step S26, and then the process ends.

(3) On the other hand, when the user actually goes shopping and retrieves the input and stored data, a read mode as shown in FIG. 5 is executed. This mode is
The process is started by pressing the "view" key, and in the first step S31, the "selling floor and its remaining number" stored in the RAM 9 is read out and displayed on the display section 3. Further, in step S32, it is determined whether or not the "number of sales floor remaining" is zero, and when this determination is NO, it is determined in step S32 whether or not the "sales floor" key has been turned on. The determination in step S33 is N.

If so, the process advances to step S34, where the "store" is shifted to another one, and then the process returns to step S31, where the shifted "store" is displayed together with the "number of stores remaining". If the determination in step 333 is YES, step S
35, it is determined whether the "name" key has been turned on, and this determination is N.

When this happens, the process returns to step S31. Therefore, through the above steps S31 to S35, each time the "Sales Floor" key is turned ON, a plurality of sales floors stored in the RAM 9 are displayed in order along with the remaining number of sales floors, and when the "Sales Floor" key is turned OFF.
In this state, one sales floor continues to be displayed without being switched.

When the judgment in step S becomes YES due to the ON operation of the "name" key, the process advances to step S38, where the "product name and quantity" of the product corresponding to the "sales floor" displayed above are read out from the RAM 9 and displayed. It is displayed by section 3. After that, in step S37, the purchaser sees the above display and purchases as shown and presses the "Complete/Add" key.
It is determined whether or not the N operation has been performed. If the determination is NO, steps 33B and S37 are continued. If the determination is YES, the process advances to step S3B and the display section 3 displays "Needan?"
will be displayed. Further, in step S39, it is determined whether or not the purchaser has inputted the numerical value of the above-mentioned product price, and if this determination is No, steps 33B and S39 are repeated, and if the determination is YES, the process advances to step S40 to input the numerical value of the above-mentioned product price. The price of the purchased product is stored in the RAM 9, and the purchase price of the product thus far is accumulated. Then, in the next step S41, the cumulative amount is compared with the budget read out from the RAM 9, and it is determined whether the cumulative amount exceeds the budget. If NO, the cumulative amount is less than the budget, the display section 3 displays "" in step S42. The "cumulative amount" and "remaining number of items (number of products)" at the relevant sales floor are displayed by lighting up. On the other hand, if YES is over budget, the display unit 3 displays the "cumulative amount" and the "remaining number of items (products)" at the relevant sales floor in step S43. "Number of items" blinks. Above step S42, 5I13
After that, proceed to step S44 and set the remaining number of items on the sales floor to 1.
In step S45, it is determined whether the remaining number is zero. If this determination is NO, step 34
In step S6, it is determined whether or not the "name" key has been turned on, and if the determination is YES, the step S3! Return to l.

On the other hand, when the determination in step S45 is YES, the process proceeds to step S47, where the number of sales areas is decreased by one, and then, in step S4B, it is determined whether or not the sales area j key has been turned on. Above step S3
Return to 5. Therefore, according to the above procedure, the display of the product name, quantity, etc., as well as the cumulative total of the product purchase price and its display are repeated until the number of items on the sales floor reaches zero. When the number of items reaches zero, the sales area itself disappears and the remaining items are displayed. The sales floor will be displayed as before.

Then, when the determination in step S32 becomes YES through such repetition, the process proceeds to step S49, where "yen/
It is determined whether the "Erase" key has been turned on, and if this determination is NO, steps S31, S32.
While repeating S49, if the determination becomes YES, the process proceeds to step S50, where the cumulative total of the purchase amount is displayed on the display unit 3, and then the process ends.

(4) Also, when it becomes necessary to check the budget during shopping and the budget is to be displayed, the budget display mode shown in FIG. 6 is performed. This mode is executed by turning on the "View" key twice, and by turning the same key twice, R is activated in step 561.
The "budget" stored in AM9 is read out, and in the next step S62, the amount of the "budget" is displayed on the display section 3 as "Yosan oooo en", and then the process ends.

(5) Furthermore, when it becomes necessary to change the schedule during shopping at each sales floor and purchase additional products at that sales floor, the additional purchase mode shown in FIG. 7 is executed. That is, this mode is started by turning on the "Complete/Add" key twice, and at this time, "Name?" is displayed on the display section 3 in step S71. Furthermore, in step S72, it is determined whether or not the "product name" is input by operating the alphabet keys, and then the "↓" key is operated. If this determination is NO, step S71. While repeating S7', if the determination is YES, the display section 3 displays "Nedan?" in step S.

Thereafter, the process proceeds to step 374, where it is determined whether or not the purchaser has input the numerical value of the product price, and if this determination is No, step 873. Repeat S74 and the decision is YE.
When S is reached, the process proceeds to step S75, where the purchase amount of the products so far is accumulated, and in step S76, the display section 3 lights up and displays the ``total amount'' and the ``number of items remaining'' at the sales floor, and the process ends.

(6) On the other hand, if you notice that you are over budget or have unnecessary items at each sales floor, and you wish to return the items you have already purchased,
The return mode shown in FIG. 8 is performed. First, it is determined that the "circle/erase" key has been turned on twice, and at this time, "Name?" is displayed on the display section 3 in step S81. Furthermore, in step S82, it is determined whether or not the "item name" is input by operating the alphabet keys in conjunction with the return of the product, and then "↓" is operated. If this judgment is NO, step S group.

While repeating S82, if the determination is YES, in step S83, the display section 3 displays "Nedan?". After that, the process proceeds to step S84, where it is determined whether or not the purchaser has inputted the numerical value of the product price, and if this determination is No.
When , step S83. sM is repeated, and if the determination becomes YES, the process proceeds to step S85, where a new cumulative amount is calculated by subtracting the input amount from the purchase amount of the product so far, and in step S86, the cumulative amount and the relevant sales area are displayed on the display unit 3. The remaining number of items (number of products) will be displayed and the process will end.

In addition, when adding or returning products from a sales floor that has been passed twice due to budget adjustment, etc., it is also possible to have data such as product name, quantity, price, etc. of the product to be added or returned be entered along with the sales floor. It is.

Therefore, in this embodiment, the above-mentioned key section 4 and steps 81 to S1+ in the above-described flow constitute an input means 10 for inputting the name of the product, its quantity, and the sales floor.

Further, the RAM 9 constitutes a storage means that stores the "item name" and "quantity" data inputted by the input means 10 collectively for each "sales floor."

Furthermore, in part 4 and steps 331 to S50, the "product name" and "
An output means 11 is configured to display data on the quantity on the display unit 3 for each sales floor.

Next, the operation of the above embodiment will be explained.

First, before going shopping, data such as the products to be purchased, their quantities, sales areas, and overall budget are entered in advance through the input means 10, and these data are stored in the RAM 9 (storage means). That is, when the "start" key in the key section 4 is pressed, the input mode is entered, and when the "input/budget" key is turned on, "Uri μ?" is displayed on the display section 3. After this, if you input the department by operating the alphabet keys and turning on the "↓" key (for example, "vegetable department")
Or, when entering “greengrocer”, press the “Y/7” key.
rA/gJ key rS/2J key rA/lrJ key
Next, "Name?" will be displayed on the display section 3, and if you input the product name by operating the alphabet keys and turning on the "↓" key (for example, "tomato") To input, press the rT/3J key, ``0/box'' key, rM/6J key, ``A/gJ key, rT/3'' key, and ``0/box'' keys in order), and the display 3 will display ``Surariyo?''. is displayed. Furthermore, if you input the quantity by operating the alphabet keys and turning on the "↓" key (for example, when inputting "3 pieces", press the "Shift" key followed by the "T/3" key r
1/item" keys in sequence), the data related to the products that have been input to the display section 3 are displayed all at once on the display section 3. When this display is correct, turn on the ``YES/NOJ'' key once, and with this operation, the ``item name'' and its ``quantity'' are stored in the RAM 9 in a group for each ``sales floor''. On the other hand, if the data is incorrect and you want to cancel it, press the rYES/NOJ key twice in succession.
If this operation is performed, the data will be canceled and will not be stored in the RAM 9. Thereafter, in the same way as above, the user is prompted to input data on the sales floor, product name, and quantity for each product in an interactive format.

Also, when inputting a budget, turn on the "Input/Budget" key twice in succession to enter the budget input mode. When you enter the budget amount by operating the keys and turning on the "↓" key (for example, "
To input ¥2,000 as "Budget", press the "Shift" key, then the rS/2J key, "0" key, "0" key and "0" key in order), and display 3 will display "Yosan oooo en". Is displayed. When this display is correct, you only need to turn on the rYES/NOJ key once.
With this operation, the budget data is stored as is in the RAM 9. On the other hand, if the data is incorrect and you want to cancel it, press the rYES/NOJ key twice and press the
When the N operation is performed, the data is canceled and is not stored in the RAM 9.

On the other hand, when actually going shopping and reading out data, the user turns on the "view" key in the key part 4 to enter the read mode. In this mode, first, one of the plurality of sales spaces stored in the RAM 9 is displayed on the display section 3 together with the total number of sales spaces remaining. This displayed sales floor is “
Each time the "Sales Floor" key is turned on, the display is shifted and the remaining sales floors stored in the RAM 9 are sequentially switched and displayed.

Therefore, you can understand the entire sales floor before actually shopping, and even when you go to a supermarket or shopping district for the first time, or when the sales floor location of a supermarket etc. has changed from before, you can understand the entire sales floor. You can know the exact route.

When arriving at one of the multiple sales floors displayed in the above category, the search procedure described above reads out the sales floor and displays it on the display section 3, and in that state, "
Turn on the "Name" key.

By this operation, one piece of data (product name and quantity) of the product corresponding to the sales floor is read out from the RAM 9 and displayed on the display section 3. Therefore, it is sufficient to carry out shopping according to the displayed data (specifically, for example, at a sales floor of a supermarket, etc., a process is performed in which displayed products are placed in a provided basket). After shopping, when you turn on the "Complete/Add" key, "Nedan?" is displayed on the display section 3 to ask about the price of the purchased item, and when you press the alphabet keys and press the "Yen/Delete" key. When the price of the product is input by turning on , the cumulative total of the amounts input so far is calculated and displayed on the display section 3 along with the number of items remaining (number of products) in the sales floor. The cumulative amount is compared with a budget that has already been set, and when the cumulative amount exceeds the budget, the display on the display section 3 flashes. Therefore, it is possible to know with certainty whether the budget is over. Thereafter, the data regarding the purchased product is subtracted from the product data at the sales floor, and the input/output of data regarding one product is thus completed. Thereafter, the same procedure as above is repeated for other products on the same sales floor. In this way, the stored products for each department are displayed one by one, and the data for the next product is not displayed unless you press the "Complete/Add" key, which effectively prevents you from forgetting to buy a product. can.

Furthermore, when all products on a sales floor are purchased and the remaining number becomes zero, the data for that sales floor is subtracted from all sales floors. Next, when the "Sales Floor" key is turned on, the display returns to the initial state and the remaining sales floors are displayed on the display section 3 along with their remaining numbers. After this, when the user moves to the next sales floor and performs the same operation as above, the product data for that sales floor is read out and displayed. Thereafter, the same procedure is repeated.

When checking your budget in the middle of shopping like this,
When the user presses the "View" key twice, the budget is read out from the RAM 9 and displayed on the display section 3.

In addition, if it becomes necessary to purchase a product that was not in the plan at each sales floor, the above "Complete" button will be displayed at the same time as the purchase
Turn on the "Add" key two or more times in a row. By this operation, "Name?" is displayed on the display section 3. If you input the product name using the alphabet keys in response to this display, a display asking for the price of the product will be displayed on the display unit 3.
When you enter a price using the numeric keypad, the cumulative amount will be displayed along with the number of items remaining on the sales floor.

Furthermore, when returning a purchased product, press the "yen/delete" key two or more times in a row to return the product.
Manipulate. By this operation, "Name?" is displayed on the display section 3. If you input the product name using the alphabet keys in response to this display, a display asking for the price of that product will appear on the display 3. When you input the price using the numeric keypad, that amount will be subtracted from the previous cumulative amount and a new value will be displayed. The cumulative amount is calculated and displayed on the display section 3 together with the number of items remaining on the sales floor.

In addition, when calculator A is connected to an external computer using the input/output connector of case 1, if you turn on the "output" key in key part 4, the data stored in RAM 9 of calculator A will be transferred to the external computer. This data is sent to a computer, and by processing this data on an external computer, household finances can be automatically managed and facilitated.

In addition, when adding or returning a product from a store that you have passed through twice, if you are required to enter data such as the product name, quantity, price, etc. of the product to be added or returned along with the store, the store name will be the same as the product. Since the information is stored together with the item name, etc., it is advantageous for automating the above-mentioned household budget management.

Therefore, in this example, before going shopping,
If you input the product name, quantity, and sales floor of the product you want to purchase in advance, the data on the product name and quantity will be stored in the RAM 9 for each sales floor, and when you actually go shopping, you will be able to read the stored product name. Since the information and quantity are called up for each sales area and displayed on the display unit 3, the purchaser can recognize each sales area, and then recognize all the products to be purchased at that sales area, and move through each sales area in order. The customer can reliably purchase products at each sales floor, and only needs to visit one sales floor once, eliminating the need to go back and forth between sales floors unnecessarily, and thereby greatly reducing shopping effort.

(Effects of the Invention) As explained above, according to the shopping calculator of the present invention, a plurality of types of products and their quantities are classified and memorized for each sales floor before going shopping, When the output operation is performed, the stored data is displayed in order for each department, so the purchaser can look at the display on the calculator and purchase the necessary products for each department in order, which is useful in stores such as supermarkets. This has an excellent practical effect in that it allows a smooth transition without having to go back and forth between stores and shopping streets unnecessarily, and it can greatly reduce the effort required for shopping.
