Description

The invention relates to commercial equipment and can be used in retail trade in bulk goods and household weighing and calculations.

Known manual spring scales (ed. St. USSR N538239, G 01 G, 3/00, 1976), which contain an oval case with a circular dial and a ring to ensure the vertical position of the scales and the weighed load.

The low information content of the circular dial (only the weight value) no longer meets the requirements of modern retail trade, and the use of a thin ring creates inconvenience when using the scales, especially when the load is heavy.

Known electronic scales with indication of price, weight and cost of goods (ed. St. USSR N429287, G 01 G, 19/40, 1974), which contain a load pad mounted on a load-receiving mechanism, a force meter, price and indication input units weight and cost.

A disadvantage of the known electronic scales is that due to the relatively high energy intensity of the electromechanical force transducers, they are manufactured in a stationary version powered by a network or capacious current sources.

Piezoelectric transducers used as sensitive elements in electronic scales (for example, ed. St. USSR N437918, G 01 G, 3/16, 1974) will make it possible

the latter in a mobile (manual) version with autonomous low-capacity power supply.

Electronic scales with price indication; weight and cost of goods by author. St. USSR N429287, G 01 G, 19/40, 1974, was selected as a prototype of the invention.

The purpose of the invention is to increase the functionality, reliability and convenience of the weighing procedure on manual electronic scales, especially in conditions of retail trade.

This goal is achieved by the fact that on the front case of hand-held electronic scales there is a key that includes calculator mode, a key for fixing indicators, individually activating each of the indicators, its corresponding storage device and operation key, and keys for entering the contents of the indicators into memory and output its into indicators from memory. The keys on the front panel of the handheld electronic scale housing allow you to use the balance in the household calculator mode, save the indicators until complete settlement with the customer, and activate a separate indicator with its corresponding storage device, the addition key, and the key to enter the contents of the indicators into memory and output it to the indicator from memory makes it possible to reproduce the previous readings of each indicator, determine the sum of these readings, determine the price of the goods with knowledge of e the cost and determine the weight (which is particularly important in street vending) and use other features, the description of which is given below.

As well as the fact that the lateral and rear parts of the body of hand-held electronic scales have a relief that corresponds to the relief of a bent hand, which creates convenience when using the scales, especially with a significant weight of the goods, and improves the quality of service.

And also by the fact that in the case of the scales there is at least one oval hole for the fingers of the hand, which increases the reliability of fixing the scales during use, allows you to keep the scales on your finger or in a special hanger between the weighings.

The invention is illustrated by drawings, where figure 1 shows the proposed manual electronic scales, figure 2 and figure 3 - embodiments of the housing of manual electronic scales.

Hand-held electronic scales contain a rigid case with built-in self-contained power supply (not shown), an electromechanical force transducer (for example, a piezoelectric transducer of gravity of the weighed load into a frequency signal at the output of the sensor) electrically connected to a digital microprocessor and mechanically connected to a weight hook (transducer and microprocessor not shown). On the front panel of the scale body there are indicators of price, weight and cost, as well as keys that have the following purpose:

“Vk” - power on / off key;

“K” - on / off key for calculator mode;

“Ц” - activation key of the “PRICE” indicator, corresponding storage device and arithmetic addition operation;

“F” is the key to fix the indicators and save them after removing the load from the weight hook, pressing this key again will clear the “COST” and “MASS” indicators and activate the “PRICE” indicator.

“C” - activation key of the “COST” indicator, corresponding storage device and arithmetic addition operation;

“M” - activation key of the “MASS” indicator, corresponding storage device and arithmetic addition operation;

“> P” - key to enter the indicator reading into memory;

"<П" - a key of a conclusion of indications from memory in the indicator;

“0”, “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9” - number keys;

“.” - decimal point key;

“+”, “-”, “*”, “:” - keys of arithmetic operations;

“=” Is the key for performing arithmetic operations.

The current state of microelectronics and the development of microprocessors fully ensures the performance of all the functional operations laid down in the invention, including the automatic output of the value in the indicator corresponding to the set values in any two other indicators. The memory devices of the indicators can, for example, be based on a stack memory, which is organized according to the principle of store memory, when sequentially recorded information is read only in the reverse recording sequence (the last recorded number is read first). After reading the information is stored in the memory cells, which allows you to use it repeatedly. The recorded information is erased after turning off the power to the balance.

The rigid case of the scales has a flat front panel with indicators and keys, and the side and back surfaces are made in relief, which corresponds to the relief of a bent hand, in particular, there is a bulge (not shown) on the back of the case, inside

which strengthened the electromechanical force transducer, and the bulge itself corresponds to the hollow of the palm of a bent hand.

Manual electronic scales work as follows.

In the initial state, the weight hook is removed and fixed in a special niche in the back of the weighing case (not shown).

a) In this position, hand-held electronic scales are conveniently used as a household calculator. To do this, turn on the balance with the "Bk" key and press the "K" key - the balance works in calculator mode. The indicator of the calculator is a multi-digit indicator “COST”. To switch the operation to the scale mode, press the "K" key again.

b) To use the device in the mode of scales in the initial state, remove the weight hook from the niche and set it into working position, thereby mechanically communicating with the electromechanical force transducer. Then, using the “Vk” button, the balance is powered up.

After that, the following operations are performed.

1. Press the “Ts” key, which activates the “PRICE” indicator and the cells of the corresponding storage device. Using the digital and decimal points, the price of the goods sold is entered into the indicator.

2. Weighed goods are fixed on the weight hook. The “MASS” and “COST” indicators will automatically display the corresponding values. After the termination of fluctuations in the goods being weighed, press the "Ф" key to fix the indicators and save them after removing the load from the weight hook until complete settlement with the buyer.

3. Having finished the sales act, press the key "> П", which brings the readings of the activated indicator "PRICE" into the memory cell of the corresponding storage device.

4. Then press the “C” key, which activates the “COST” indicator, the corresponding storage device and the arithmetic operation of addition. After that, press the key "> P", which brings the readings of the indicator "COST" into memory.

5. Then press the “M” key, which activates the “MASS” indicator, the corresponding storage device and the arithmetic addition operation. After that, press the key "> P", which brings the readings of the indicator "MASS" into the memory cell of the corresponding storage device.

6. Having written down the indications of the indicators in the memory of the corresponding storage devices, press the "Ф" key, this leads to the clearing of the indicators in addition to the activated indicator "PRICE", and the next act of weighing and buying and selling the same product is repeated by repeating steps 2-6.

7. If the sale of another product begins, then after operation 6, a new price is entered into the activated indicator “PRICE” and operations 2-6 are repeated.

c) If the price of the goods has already been recorded in memory, then it can be found and displayed in the activated indicator “PRICE”. To do this, press the key to display the contents of the memory on the indicator "<P" so many times until the desired value appears on the "PRICE" indicator. After that, perform operations 2-6.

d) To determine the amount of money earned from the sale of goods (the spent amount of money for the purchase of weighted goods for the buyer), press the "C" key and add up the indicators alternately recalled from the memory by pressing the "<P" key.

d) To determine the quantity of the sold (bought for the buyer) weighted goods, press the “M” key and then add the indicators that are alternately called up from the memory to the indicator by pressing the “<P” key.

f) To determine the value of several piece goods, enter the value of the unit price into the activated PRICE indicator, then enter the number of piece goods into the activated indicator "MASS". The “COST” indicator will automatically display the value of the sold piece goods.

g) To determine the price of goods purchased “with hands” (bucket, package, etc.), press the “C” key and enter the requested amount. Then, after weighing, the PRICE indicator will find out the price of the product, compare it with the price determined in the same way, another seller and make an economical purchase.

h) To determine their purchasing power (especially for pensioners), press the “C” key and enter the available cash amount. Then, press the "Ц" key and enter the price of the goods - the "WEIGHT" indicator will indicate the maximum weight that you can buy, or the number of piece goods.

i) Since sequentially recorded information in the memory is read only in the reverse sequence of recording, this allows for any misunderstandings to reproduce the indicators of any previously made sale (purchase) of goods.

After the purchase and sale acts and other operations are completed, the scales are turned off with the “Bk” key (the recorded information is erased after the balance is turned off), and the weight hook is fixed in a special niche in the back of the scale body.

The relief of the surface parts of the housing of the hand-held electronic scales shown in figure 1 works as follows.

Due to the fact that the lateral and rear parts of the scale body have a relief that corresponds to the relief of a bent hand, the scales come into contact with the palm of the hand on their maximum surface, which creates convenience when using the scale and improves the quality of service. The protrusions in the upper part of the scales during weighing rest on the phalanges of the thumb and forefinger, which eliminates their slipping, especially with a significant weight of the product, which increases the reliability of the weighing procedure and meets safety requirements.

One oval hole in the housing of the scales depicted in figure 2 works as follows.

Due to the relief of the body part, the scales come into reliable tight contact with the palm of the hand, and the index finger placed in the hole increases comfort and gives a reliable guarantee against slipping out during the weighing procedure. In addition, the oval hole allows you to keep the scales on your finger or a special hanger (nail) in between weighings.

Two oval holes in the upper part of the housing of the scales depicted in figure 3 work as follows.

The index finger and thumb placed in the holes and a bulge (not shown) on the back of the case, which corresponds to the hollow of the palm of a bent hand, ensure reliability

and comfort during the weighing procedure and during storage during breaks. In addition, the presence of two oval holes in the upper part and a bulge corresponding to the hollow of the palm of a bent hand on the back of the case reduces the requirement for embossed execution of the side walls of the scales
