(2-2) Camera As shown in FIGS. 1 and 2, the camera 12 is mounted on a support member 12 a provided over the two columns 10 a and 10 b in the vicinity of the first and second touch panels 16 a and 17. It is attached. The camera 12 is attached from above the weighing unit 11 so that an object to be weighed placed on the placing table of the weighing unit 11 can be imaged. The camera 12 detects the size of the tare of the object to be weighed placed on the placing table of the weighing unit 11. The detected tare size of the object to be weighed is used for the tare specifying operation by the control unit 30 described later.

  In addition, when a member card is placed on the placing table of the weighing unit 11, the camera 12 can read the member identification information displayed on the member card. Specifically, it is assumed that there is a member card issued by a store, and the card is written with a barcode representing member identification information such as a member number. If the surface to which the barcode of the member card is attached is placed on the placing table before the weighing object is placed on the placing table and the weighing operation is performed, the camera 12 will be the member The barcode of the card, that is, the member identification information is read. The read member identification information is used for a coupon ticket issuing operation described later. Note that the membership card is not particularly limited as long as it can read information on the membership, and may be, for example, an IC card or a magnetic card.

  Further, the camera 12 can take an image of an operation in which a label is attached to the tare by the customer on the mounting table of the weighing unit 11. Therefore, when the customer intentionally attaches another label different from the label corresponding to the object to be weighed, this operation is imaged, which is effective in finding fraud.

(2-3) Human Sensor The human sensor 13 is attached to the support member 12a as shown in FIGS. The human sensor 13 is attached to the support member 12a so that the detection portion faces the front side of the weighing device 100. The human sensor 13 is configured by an infrared sensor, for example, and detects the presence or absence of a customer near the weighing device 100. The detection result by the human sensor 13 is used as a trigger for starting the guidance of the purchase procedure described later.

(2-4) Label issuing unit The label issuing unit 14 includes a label cassette, a plurality of sensors, and the like. The label issuing unit 14 prints the price of the product based on the weight of the product on the blank label fed out from the label cassette, and issues a label that the customer attaches to the tare. As the white paper used for the label, only the back side is sticky.

  FIG. 5 shows a label L1 as an example of a label issued by the label issuing unit 14. The label L1 in FIG. 5 is printed with an expiration date L2, a unit price L3 per 100 g of the product, a net amount L4 that is the weight of the product, a price L5 corresponding to the weight of the product, and a barcode L6 representing the price L5. .

  Examples of the sensor include a sensor for detecting the remaining amount of blank paper rolls contained in the label cassette, a sensor for detecting that the issued label is taken by the customer, and the like.

(2-5) Coupon issuing unit The coupon issuing unit 15 includes a cassette for printing coupons, a plurality of sensors, and the like. When the membership identification information of the membership card is read by the camera 12, the coupon issuing unit 15 issues a coupon ticket on which blank information paid out from the cassette is printed with discount information received by the member. As the white paper used for the coupon, unlike the white paper roll used for the label, a white paper which is not sticky on both sides is used.

  FIG. 6 shows a coupon ticket C <b> 1 as an example of a coupon ticket issued by the coupon issuing unit 15. A coupon C1 in FIG. 6 is printed with a product name C2 to be discounted and its discount amount C3, an expiration date C4 of the coupon C1, and a bar code C4 representing the discount amount C3.

  Here, it is preferable that the coupon is issued for a customer who has purchased the product. Therefore, the timing at which the coupon issuing unit 15 issues the coupon is, for example, the same timing as the timing at which the label issuing unit 14 issues a label after weighing the object.

  As with the label issuing unit 14, the sensor constituting the coupon issuing unit 15 detects a remaining amount of blank paper stored in the cassette, and detects that the issued coupon is taken by the customer. And a sensor for doing so.

(2-6) Customer side notifying unit The customer side notifying unit 16 includes a first touch panel 16a and a speaker 16b, as shown in FIG. That is, the customer-side notifying unit 16 is configured to be able to notify the information announced to the customer not only visually but also audibly.

(2-6-1) First Touch Panel The first touch panel 16a displays various screens for customers. In particular, when the human sensor 13 detects the presence of the customer because the customer approaches the weighing device 100, the first touch panel 16a displays the screen sc1, which is one of the purchase procedure guidance screens. Start. After displaying the screen sc1, the first touch panel 16a sequentially displays screens sc2 and sc3, which are other screens for purchasing procedure guidance.

Here, the purchase procedure referred to in the present embodiment includes an issuing operation for causing the label issuing unit 14 to issue a label and an attaching operation in which the customer attaches the label to the tare. More specifically, the purchase procedure includes the following three procedures.
Procedure 1: The customer is prompted to place the object to be weighed on the placing table of the weighing unit 11 (screen sc1 in FIG. 7).
Procedure 2: In order to issue a label including a price corresponding to the weight of the product, the customer is prompted to press the issue button sc2c on the screen sc2 displayed on the first touch panel 16a (screen sc2 in FIG. 8).
Procedure 3: The customer is prompted to attach the label issued by pressing the issue button sc2c to the tare of the object to be weighed (screen sc3 in FIG. 9).

  As shown in steps 1 to 3 above, the purchase procedure according to the present embodiment does not include a procedure for the customer to input which tare the customer has selected. This is because when the object to be weighed is placed on the weighing unit 11 by the customer, the size of the tare of the object to be weighed is detected by the camera 12 and which tare is used is automatically specified. .

  On the other hand, even when the camera 12 is used, the tare size of the object to be weighed cannot be detected, or the tare cannot be specified because the detected tare size applies to two or more types of tare. Alternatively, the screen sc4 shown in FIG. 10 may be displayed on the first touch panel 16a between the procedure 1 and the procedure 2. The screen sc4 is a screen in which the customer inputs the tare selected by the customer.

  Here, information included in the various screens sc1 to sc4 will be briefly described. On the screen sc1, the tare weight sc1a, the weight of the object to be weighed (or the weight of the product itself) sc1b, the unit price sc1c per 100 g of the product, the price sc1d of the product, and the object to be weighed are placed on the weighing unit 11. A message sc1e indicating that the object is to be placed and a moving image sc1f for placing the object to be weighed on the weighing unit 11 are included. Here, a still image or an animation image may be used instead of the moving image sc1g. The screen sc1 is displayed on the first touch panel 16a from when the customer approaches the weighing device 100 until an object to be weighed is placed on the weighing unit 11, or for a predetermined time after the customer approaches the weighing device 100. Continue to display. The tare weight sc1a, the weight sc1b of the object to be weighed, the unit price sc1c per 100 g of the product, and the price sc1d of the product are information displayed in common on the other screens sc2 to sc4.

  The screen sc2 includes a message sc2a that prompts the user to press the issue button sc2c, a tare name sc2b, an issue button sc2c, and a return button sc2d. When the return button sc2d is pressed, the screen sc1 is displayed again on the first touch panel 16a.

  The screen sc3 includes a message sc3a that prompts the user to put the issued label on the tare, and a moving image sc3b that attaches the label to the tare while the object to be weighed is placed on the weighing unit 11. Here, a still image or an animation image may be used instead of the moving image sc3b. The screen sc3 is continuously displayed on the first touch panel 16a until the customer moves away from the weighing device 100 or for a predetermined time after the screen sc3 is displayed.

  The screen sc4 includes various information sc4b, sc4c, sc4d, and sc4e relating to selectable tares, in addition to a message sc4a that prompts the customer to select a tare. Various information sc4b to sc4e regarding the tare are displayed so that any one can be selected. This screen sc4 is continuously displayed on the first touch panel 16a until the customer selects any one of the various types of information sc4b to sc4e regarding the tare or for a predetermined time after the screen sc4 is displayed. .

  In addition, when a predetermined time has elapsed since the various screens sc1 to sc4 are displayed and the customer is not near the weighing device 100, it is determined that the customer has left the purchase procedure in the middle, and even if the purchase procedure is in the middle Even if it exists, the 1st touch panel 16a complete | finishes the display of the various screens sc1-sc4.

  Moreover, in this embodiment, as shown in FIG. 11, the unit price of goods is set for every weight range of goods. Accordingly, as shown in FIG. 12, the first touch panel 16a can further display a message sc2e indicating how much more products are purchased and the unit price is reduced. FIG. 12 illustrates a case where the message sc2e is popped up on the screen sc2 corresponding to the procedure 2. The part “10g” in the message sc2e is in the weight range when the weight of the product that the customer is currently purchasing and the unit price “178 yen” of the current product is lower than this and becomes “168 yen”. This corresponds to a weight difference “10 g” from the lower limit value “601 g” (601 g−591 g = 10 g).

(2-6-2) Speaker The speaker 16b is provided in the main body 10, and outputs various information for customers by voice. In particular, when the human sensor 13 detects the presence of the customer because the customer approaches the weighing device 100, the speaker 16b is displayed in conjunction with various screens sc1 to sc4 displayed on the first touch panel 16a. Messages sc1e, sc2a, sc3a, and sc4a on the various screens sc1 to sc4 are output by voice. For example, the speaker 16b outputs a message sc1e when the screen sc1 is displayed on the first touch panel 16a and a message sc2a when the screen sc2 is displayed.

  Furthermore, when the message sc2e shown in FIG. 12 is displayed in a pop-up on the first touch panel 16a, the speaker 16b outputs the content of the message sc2e by voice in conjunction with the display.

(2-7) Second Touch Panel The second touch panel 17 displays various information for store clerk. For example, when the remaining amount of the white paper roll in the label issuing unit 14 or the coupon issuing unit 15 is equal to or less than a predetermined amount, the content is displayed on the second touch panel 17. In addition, when the number of unused tares is equal to or less than a predetermined number, a selectable tare replenishment button (not shown) is displayed on the second touch panel 17 together with the contents.

  Note that the number of used tares can be grasped from the count value of the number of times the size of the tare is read by the camera 12, the count value of the number of times the weighing unit 11 has measured, or the like. Therefore, by subtracting the count value from the maximum number of tares originally placed, the number of remaining tares that are not yet used can be grasped. On the other hand, when the tare replenishment completion button is pressed, the count value is reset.

(2-8) Store-side wireless unit The store-side wireless unit 18 is for performing wireless communication with a mobile terminal (not shown) possessed by a store clerk.

  When the human sensor 13 continuously detects the presence of the customer for a predetermined time or more, the store-side wireless unit 18 notifies the store clerk's mobile terminal to that effect. In this case, since the customer has continued for a relatively long time near the weighing device 100, it can be determined that the customer is confused for some reason. Therefore, the store clerk who has been informed of the content in the vicinity of the weighing device 100 for a predetermined time or longer can rush to the customer to respond, and can provide better service to the customer.

  In addition, the store-side radio unit 18 is configured when the remaining amount of blank paper rolls in the label issuing unit 14 or the coupon issuing unit 15 is less than a predetermined amount, or when the number of unused tares is less than a predetermined number. The contents may be transmitted to a mobile terminal owned by the store clerk.

(2-9) Communication Unit The communication unit 19 can communicate with the server 150 and the cash register terminals 160a, 160b,... Shown in FIG. In particular, the communication unit 19 according to the present embodiment uses the information related to the label issued by the label issuing unit 14 and the detection result of the camera 12 as grasping information for grasping the degree of occurrence of fraud performed by the customer. To the server 150 and the cash register terminals 160a, 160b,. The grasping information is sent to the server 150 and the cash register terminals 160a, 160b,... Every time the weighing device 100 measures the object to be weighed.

  Here, as the information regarding the label, in addition to the price of the product described in the label (L5 in FIG. 5), the time when the label was issued, and the like can be cited. Examples of the detection result of the camera 12 include an operation for attaching a label imaged by the camera 12 and the size of the tare detected by the camera 12. In particular, the camera 12 captures an overview of the entire container including the label attached to the container, and the image is transmitted to the cash register terminals 160a, 160b,. It becomes possible.

  For example, if it is determined from the amount of the product that the price displayed on the label of the object to be weighed brought into the cash register terminals 160a, 160b,. When the store clerk operating 160b,... Feels, the store clerk can determine that an illegal act has been performed by comparing the information written on the label with the grasping information. Further, the store clerk who operates the server 150 collates information regarding the product input to the cash register terminals 160a, 160b,... It is possible to grasp the degree of occurrence that is being performed. An example of a case where there is a sense of incongruity is a fraudulent act in which a malicious customer issues two labels with different prices in advance and attaches a low-priced label to the tare with the larger amount of merchandise. Therefore, every time the weighing device 100 weighs an object to be weighed, the grasping information is transmitted to the server 150 and the cash register terminals 160a, 160b,. It is possible to grasp whether or not the fraudulent act is performed. Therefore, the store side can also take some measures against the fraudulent act.

  Note that the grasping information transmitted by the communication unit 19 is accumulated on the server 150 side.

(2-10) HDD
The HDD 20 mainly stores weight range-unit price data 21 and a tare information table 22.

(2-10-1) Weight Range-Unit Price Data The weight range-unit price data 21 is data indicating the relationship between the product weight range and the unit price, as shown in FIG. The weight range-unit price data 21 is used when the first touch panel 16a displays the message sc2e shown in FIG. 12 indicating how much the product will be purchased and the unit price will be lowered.

  FIG. 11 conceptually shows the relationship between the product weight range and unit price. Specifically, in FIG. 11, the horizontal axis represents the product weight range (g), and the vertical axis represents the unit price per 100 g of product (yen). For example, the unit price of the product within the weight range of 0 g to 200 g is 198 yen, It shows that the unit price of the product within the weight range of 201 g to 400 g is 188 yen. Thus, in this embodiment, if the weight of the product is within a certain range, the unit price of the product is also a constant value, but each time the product weight increases, the unit price of the product is set to decrease. Yes.

(2-10-2) Tare Information Table The tare information table 22 is a table used for the tare specifying operation described later and the weight calculation of the product itself described later. In the tare information table 22, as shown in FIG. 13, the tare name 22a, the size related information 22b, and the tare weight 22c are associated with each other. The size-related information 22b includes the size of the tare as well as the shape of the tare when viewed from above.

  In addition, the size of the tare is represented as having a predetermined width as shown in FIG. This is given a predetermined width in consideration of the detection error of the camera 12 that automatically detects the size of the tare.

(2-11) Control Unit The control unit 30 is a microcomputer configured with a CPU, a RAM, and a ROM, and is connected to various components that configure the weighing device 100. The ROM stores a control program for controlling the weighing device 100. The CPU controls the weighing device 100 based on a control program stored in the ROM. The RAM functions as a so-called work memory when the CPU executes a control program stored in the ROM.

  In particular, the control unit 30 according to the present embodiment performs a tare specifying operation, a product price calculating operation, guidance control of a purchase procedure based on the detection result of the human sensor 13, and the like. In order to realize such an operation, as shown in FIG. 4, the control unit 30 includes a specifying unit 31, a product weight calculation unit 32 (corresponding to a calculation unit), a weight difference calculation unit 33, a label information generation unit 34, a coupon. It functions as an information generation unit 35, a notification control unit 36, and a communication control unit 37.

  In the following, for convenience of explanation, the main body of the operation performed by the control unit 30 is assumed to be performed by each functional unit of the control unit 30, and the name of each functional unit (specifically, the specifying unit 31 or the like). Let's represent.

(2-11-1) Identification Unit The identification unit 31 identifies the tare selected by the customer based on the size of the tare detected by the camera 12. Specifically, when the size of the tare is detected by the camera 12, the specifying unit 31 applies the detection result to “size related information 22b” in the tare information table 22 of FIG. The tare selected by the customer is specified from the “tare name 22a” on the record corresponding to the information 22b ”. For example, if the detection result by the camera 12 is “circular” and “diameter is 140 mm”, the specifying unit 31 specifies that the tare selected by the customer is “container b”.

(2-11-2) Product Weight Calculation Unit The product weight calculation unit 32 first extracts the tare weight by applying the tare name specified by the specifying unit 31 to the tare information table 22. Accordingly, if the tare selected by the customer is “container b”, the product weight calculation unit 32 extracts the tare weight 22c “9 g”.

  Next, the product weight calculation unit 32 calculates the weight of the product by subtracting the extracted tare weight from the weight value of the object to be weighed by the weighing unit 11. That is, since the weight value of the object to be weighed includes not only the weight of the product but also the weight of the tare containing the product, the product weight calculation unit 32 uses the extracted tare weight. The weight of the product itself is determined. For example, when the weight value of the object to be weighed in the container b is 600 g, the weight of the product itself is 591 g (600 g−9 g = 591 g).

  Furthermore, the product weight calculation unit 32 also calculates the price of the product by multiplying the weight of the product itself by the unit price of the product. The tare weight used to calculate the weight of the product itself, the weight of the object to be weighed or the weight of the product, the unit price of the product, and the calculated price of the product itself, as shown in FIGS. Displayed by sc2 and sc3.

(2-11-3) Weight Difference Calculation Unit The weight difference calculation unit 33 includes a message sc2e in the message sc2e to display on the first touch panel 16a the message sc2e of FIG. The weight difference “10 g” is calculated. Specifically, the weight difference calculation unit 33 calculates the weight difference between the weight of the product that the customer is currently purchasing and the lower limit in the weight range when the unit price of the current product is lower than the weight. For example, if the weight of the current product is 350 g, the unit price of the product is 188 yen (FIG. 11), but the lower limit value of the product weight when the unit price of the product is 178 yen is 401 g. The weight difference calculation unit 33 subtracts the current product weight “350 g” from the lower limit value “401 g” to calculate the minimum product weight necessary for the product unit price to decrease as the weight difference “51 g”. To do.

(2-11-4) Label information generating unit The label information generating unit 34 generates information written on the label by the label issuing unit 14. That is, the label information generation unit 34, like the label L1 shown in FIG. 5, the expiration date L2, the unit price L3 of the product, the net amount L4 that is the weight of the product itself calculated by the product weight calculation unit 32, the price of the product L5 and a bar code L6 representing the price are generated.
