BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a showcase built-in scale used in a showcase used for face-to-face sales.

[0002]

2. Description of the Related Art In face-to-face sales, a "charge calculation scale" is placed on a showcase where products to be sold are arranged, and a salesperson per unit weight of the product taken out of the showcase is used as a scale by a clerk. After setting, the product taken out of the showcase is placed on the plate of the charge calculation scale, the sales price is calculated inside the charge calculation scale, and the sales price is displayed on the price display window of the charge calculation scale.

[0003] In such a configuration, it is necessary for a clerk to manually set the selling price of the merchandise according to the merchandise to be sold, one by one, and this is troublesome.

To cope with this, Japanese Patent Laid-Open No.
There is a method of automatically setting a unit price in an electronic digital toll scale disclosed in Japanese Patent Application No. 19260. This method of automatically setting a unit price includes a method of installing a plurality of detectors on the display case shelf side and in a position close to each display plate in association with each display plate, and connecting each detector to the unit price setting device in the weighing unit. , The approach of the hand of the measuring instrument is detected by the corresponding detector, and the unit price setting unit sets the desired unit price by the detection signal. According to this unit price automatic setting method, when a product is taken out, this product taking-out operation is detected by the detector, so that the unit price of the taken out product is automatically selected and set.

Further, Japanese Utility Model Laid-Open Publication No. 52-91080 discloses a weighing shelf capable of detecting the number and weight of products taken out. This weighing rack is provided with a weighing transmitter for each basket of products and provided with a selection switch for selecting the weight of one product, and it is also shown that a storage circuit for weighing is provided. By performing the operation, the number of products taken out can be calculated, and the weight of the products taken out can be detected. Further, it is disclosed that by providing a unit price setting circuit instead of the unit weight setting circuit, the total price of the stock amount can be remotely calculated.

Therefore, by combining the above two configurations, the unit price of the taken out product is automatically detected, the weight of the taken out product is automatically detected, and the selling price of the product is automatically calculated. It is also conceivable that this will be possible.

[0007]

However, the above-mentioned 2)
When a combination of the two conventional configurations is manufactured, a weighing unit is required for each basket or dish of the product, and the manufacturing cost is increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a showcase built-in scale capable of automatically calculating a selling price of a product while keeping manufacturing costs low. .

[0009]

In order to solve the above-mentioned problems, a showcase built-in scale according to the present invention comprises a load converter for measuring the weight of a showcase shelf on which a plurality of dishes on which goods are placed are placed. A load elimination unit that sets a load value measured by the load converter as a reference value, and detects a clerk's operation on a product that is individually provided in the vicinity of a product removal operation path for each clerk's plate or in the vicinity of each plate. Operation detecting means, a unit price setting unit in which a selling price per unit weight of a product placed on each plate is set, and a price per unit weight of the product on the plate based on the detecting operation of the detecting means. And a unit price selection unit for selecting and outputting the net weight of the product taken out of the plate, subtracting the load value measured by the load converter from the reference value, and calculating the net weight and the output of the unit price selection unit. Characterized in that a price calculation unit for calculating a selling price of the product and a price per unit weight that.

[0010]

According to the above configuration, when the commodity is taken out from the plate after the reference value is set by instructing the load erasing section,
This operation is recognized by the detecting means, the product taken out is specified, the required unit price is automatically output via the unit price selection unit, and the net weight of the product taken out of the plate is calculated by the price calculation unit. At the same time, the selling price of the product is automatically calculated from the net weight and the price per unit weight output from the unit price selection section. Since the load transducer measures the weight of the showcase shelf on which a plurality of dishes on which products are placed are placed, the load transducer needs to be the same as the number of shelves, and the number of load transducers can be reduced. Less than the number of dishes,
Manufacturing costs are reduced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a scale built into a showcase according to the present invention. FIG. 1 shows a showcase built-in scale according to the present invention.

Each shelf 2 inside the showcase 1 is designated via load cells 3 and 3. A plate 6a on which a first product 5a is placed is placed on a first section 4a of the shelf 2, and a plate 6b on which a second product 5b is placed is placed on a second section 4b.
Is placed. The weighed values of the load cells 3 and 3 are summed and input to the load elimination unit 7. The load erasing unit 7 stores the weighed value at the time when the load erasing button 8 is operated as a reference weight, and subtracts the reference weight from the sometimes weighed value and outputs the result. In addition, the first product 5a or the second product 5b is
, The removed weight is output as a negative weight value, but the load elimination unit 7 subtracts the reference weight from the inverted value of the measured weight and outputs the weight as a positive weight value.

Proximity sensors 9a and 9b as detecting means are arranged at positions near the first section 4a and near the second section 4b of the shelf 2. The unit price setting unit 10a has the first
The price 11a per 100 grams of the product 5a is set, and the price 11b per 100 grams of the second product 5b is set in the unit price setting section 10b. The unit price selection unit 12
Based on the outputs of the proximity sensors 9a and 9b, the proximity sensor 9
When a detects the approach of a clerk, the unit price 11a set in the unit price setting unit 10a is selected and output. When the proximity sensor 9b detects the approach of a clerk, the unit price setting unit 10b is selected.
Is selected and output.

The price calculation unit 13 calculates the sales price of the product from the unit price output from the unit price selection unit 12 and the net weight value output from the load elimination unit 7 and displays the price on the display unit 14.
The display unit 14 displays the unit price and net weight supplied to the input side of the price calculation unit 13 in addition to the sales price calculated by the price calculation unit 13.

[0015] With this configuration, the clerk first operates the load erasing button 8 and then operates the first merchandise 5 a on the shelf 2.
Or, of the second product 5b, for example, the first product 5a
When the required amount is taken out and the proximity sensor 9a detects the hand of the attendant, the unit price selection unit 12 automatically sets the unit price of the first product 5a in the price calculation unit 13, and the price calculation unit 13 Since the sales price is displayed, the attendant does not need to manually set the sales price.

Also, since the showcase shelf 2 is supported by the load cells 3 and 3 to calculate the weight taken out by the loss-in-weight weighing method, it is necessary to put the taken-out product on the platen of the scale. Nor.

Moreover, the products 5a and 5b and the plurality of dishes 6
Since the weight of the entire shelf 2 of the showcase including the a and 6b is measured, even when a large number of products 5a and 5b and plates 6a and 6b are placed on the shelf 2, a load converter such as the load cell 3 is used. The same number of shelves 2 can be used, and the manufacturing cost is reduced.

In the above embodiment, the selling price, unit price and net weight value of the first product 5a and the selling price, unit price and net weight value of the second product 5b are displayed on the common display unit 14. , Which correspond to the goods on display, in the first category 4
A display unit dedicated to the first product 5a is provided near a, and a display unit dedicated to the second product 5b is provided near the second section 4b. , The unit price, and the net weight value may be displayed separately by the detection output of the proximity sensors 9a and 9b on a display dedicated to the first product 5a or a display unit dedicated to the second product 5b.
