2. Description of the Related Art Conventionally, in stores such as supermarkets, fresh foods such as meat and seafood are sold by weighing. If you do this weighing sale,
A scale is used because it is necessary for a customer to weigh a desired quantity of a product at the time of selling the product. In the case of weighing sales, since it is necessary to calculate the price of the product by multiplying the weight of the product by the unit price of the product, a so-called toll scale in which a price calculation function of the product is added to the above-described scale is often used. I have. In the above-mentioned stores, ECR is used as a device that performs calculation processing such as product registration and settlement and outputs various reports on sales data.

[0003] Under such circumstances, in recent years, a so-called face-to-face sales electronic balance (hereinafter simply referred to as an electronic balance) has been added to the above-mentioned toll scale with a function of registering and adjusting goods and a function of outputting various reports on sales data. Scale) has been developed and put into practical use. The details of this type of electronic balance are described in Japanese Patent Application Laid-Open No. 63-2844 previously proposed by the present applicant.
See No. 28 publication.

[0004] However, the above-mentioned electronic balance is obtained by adding a part of the ECR function to the charge balance, and does not have all the functions of the conventional ECR. In addition, it can issue receipts, but does not have a journal printing function or a slip (slip) printing function. For this reason, conventional electronic scales for face-to-face sales are suitable for small-scale stores with relatively low sales, but if you want to aggregate more detailed sales data in stores with high sales, or use credit cards In tenants such as department stores that often need to print on slips for settlement processing by
Not used much.

[0005] Therefore, conventionally, in a tenant such as a store or a department store having a large sales amount, a separately constructed ECR is required.
And a weighing device using a product sales system that is electrically connected using a cable. E of this product sales system
The CR calculates the price of the product based on the set unit price and the weight signal from the weighing device, and performs a registration process based on the calculated price. For details of the merchandise sales system described above, refer to Japanese Patent Application Laid-Open No. 55-103668.

Recently, a bar code scanner is connected to the ECR, and the bar code attached to the product is read by the bar code scanner, thereby automatically inputting product data. Used.

[0007]

The degree of freedom in arrangement is small, and there are many restrictions on arrangement. (2) In addition, since the ECR and the weighing device are connected by a cable, a clerk or a customer may hook a certain cable on a foot to break the connector portion, or drop the weighing device or the ECR from the upper surface of the showcase. There is a risk of doing so. (3) In addition, in order to respond to individual users' requirements, the manufacturer must separately manufacture an ECR for connecting a barcode scanner in addition to an ECR for connecting a weighing device. In addition, parts management and manufacturing management are troublesome.

The present invention has been made under such a background, and an object of the present invention is to provide an electronic cash register which is small and lightweight, and has an electronic balance function.

As shown in FIG. 6, these are placed so as to be stored in four leg storage sections 13, 13,... Of storage recesses 12 formed in the ECR main body. Then, the measuring unit 10 and the ECR
The main body is electrically connected by a connector (not shown).

In FIG. 5, reference numeral 14 denotes a load cell.
A total of four strain gauges 16, 16, and 2 are respectively provided on the upper and lower beams formed by the holes 15 a of the flexure element 15.
…… are adhered. This load cell 14
The fulcrum member 17 is formed integrally with the fulcrum side 14a, and the fulcrum member 17 is fixed to the upper surface of the substrate 18. Also,
A mounting plate 19 is mounted on the important side 14 b of the load cell 14, and a lower surface 4 of the weighing pan 10 a is mounted on a mounting portion 20 such as a rubber bush provided at four corners of the upper surface of the mounting plate 19.
A weighing dish 10a is attached by fitting a projection 10b formed at a corner.

In FIG. 5, reference numeral 21 denotes a cover of the measuring unit 10, a part of which forms a part of the ECR cover when the measuring unit 10 is incorporated in the ECR body. 2
Reference numeral 2 denotes a base having a U-shaped cross section, to which two legs 11 are attached, and two adjustment screws 23 penetrating the substrate 18 are attached rotatably. The cover 21 is provided with an adjustment through hole 21a at a position corresponding to the adjustment screw 23, into which a driver or the like for rotating the adjustment screw 23 is inserted.

A leveler 24 indicates that the measuring section 10 is in a horizontal state. A liquid containing air bubbles is put in a cylindrical transparent glass container, and the upper end surface of the container is placed inside. Sealed with protruding spherical glass. And when the bubble is located at the center of the spherical glass,
The leveler 24 indicates that it is in a horizontal state. still,
The weighing dish 10a and the cover 21 are provided with see-through windows 10c and 21b, respectively, at positions corresponding to the weighing dish 24 so that the leveling instrument 24 can be seen through from above the weighing dish 10a.

In such a configuration, the operator places the ECR body in which the weighing unit 10 is stored in the storage recess 12 at a predetermined place such as the upper surface of a showcase, and then removes the weighing dish 10 a from the mounting plate 19. In this state, while looking at the leveler 24 from above the cover 21, as shown in FIG. 7, a driver is inserted into the adjustment through-hole 21 a and the adjustment screws 23 attached to the four corners of the base 22 are rotated. The level of the measuring unit 10 is adjusted so that the bubble of the leveler 24 comes to the center of the spherical glass. At this time, the height of the substrate 18 changes, but the cover 2

Then, the projections 10b formed at the four corners of the lower surface of the weighing dish 10a are fitted to the attachment portions 20 provided at the four corners of the upper surface of the attachment plate 19 to assemble and use the ECR. When dealing with weighed products, this ECR sets the unit price of the product in advance, and when the product is weighed, the price of the product is calculated and displayed on the display unit 2, and the weight of the product becomes the weight desired by the customer. In this case, when the operator presses the "+" key, which is one of the function keys, the product is registered. When handling fixed-price products, processing similar to that of a normal ECR, that is, an ECR to which an electronic balance is not connected is performed. For a specific example of the registration process,
Since it is publicly known, its description is omitted.

As described above, according to the above-described first embodiment, the position of the cover 21 of the measuring unit 10 does not change even if the horizontal state of the measuring unit 10 is adjusted. The adjustment does not impair the beauty of the entire ECR as compared with the case where the height of the unit is adjusted to adjust the height of the entire measuring unit 10. After the weighing unit 10 is assembled in the ECR main body, the horizontal state of the weighing unit 10 can be adjusted independently of the ECR main body with the weighing pan 10a removed. Further, since the adjusting through-hole 21a is covered by the weighing dish 10a when using the ECR, it is invisible to the clerk and the customer,
Does not spoil the beauty of CR. In addition, since the horizontal adjustment of the weighing unit 10 is performed not by moving the entire ECR but by the weighing unit 10 only, the weight of the portion to be adjusted is small and the adjustment operation is easy.

Next, a second embodiment of the present invention will be described. Some ECRs are connected to a barcode scanner that reads code data corresponding to a barcode from a barcode printed portion of a product. The ECR to which the barcode scanner is connected reads a barcode attached to a product and performs a registration process of the product. Therefore, when registering a product with a barcode scanner, the condition is that the price of the product has already been determined. On the other hand, in the case of the weighing sale using the weighing unit 10 of the first embodiment described above,
The price of the product is not determined until the product is weighed. That is, even if the same ECR is connected to a weighing unit (electronic scale) and a barcode scanner is connected, the usage form is different. Therefore, an ECR having both a weighing unit and a barcode scanner is generally used. Not required.

Recently, with the advance of optical systems and semiconductor technologies, extremely thin and small fixed barcode scanners have been developed.

Therefore, in the second embodiment, in view of the above points, the fixed barcode scanner is configured to have substantially the same shape as the weighing unit 10 of the first embodiment, and
0 and a fixed barcode scanner are configured to be interchangeably attached to the ECR body. FIG. 8 is a block diagram showing an electrical configuration of the ECR according to the second embodiment of the present invention. In this figure, parts corresponding to the respective parts in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. 8, the barcode scanner 25 described above is newly provided in place of the weighing unit 10 of FIG. Here, FIG.
FIG. 8 shows a front sectional view of the ECR shown in FIG. It should be noted that detailed cross sections other than the barcode scanner 25 are omitted. This barcode scanner 25 is similar to the weighing unit 10 in FIG.
Legs 1 each having a substantially rectangular parallelepiped shape and provided at four lower corners thereof
Are recessed storage portions 1 formed in the ECR main body.
Are mounted so as to be stored in the two four leg storage sections 13, 13,.... Then, the barcode scanner 25
And the ECR main body are electrically connected by a connector (not shown).

In FIG. 9, reference numeral 26 denotes an optical system which reads a bar code from a bar code printed portion of a product held over a reading window 25b provided on the upper surface of a cover 25a of the bar code scanner 25. S1 is a reflection type optical sensor that detects a through hole (not shown) provided on the side surface of the barcode scanner 26 and determines that the device attached to the storage recess 12 of the ECR main body is the barcode scanner 26. To detect. S2 is a reflection type optical sensor which detects a through hole (not shown) provided on the side surface of the measuring section 10 and performs EC detection.
The device attached to the storage recess 12 of the R body is the measuring unit 1
0 is detected.

As shown in FIG. 10, the ROM 8 of FIG. 8 includes a control program A area 8a in which a control program A used when the measuring section 10 is mounted in the storage recess 12 of the ECR main body is stored. And a control program B area 8b in which a control program B used when the barcode scanner 25 is attached to the storage recess 12 of the ECR main body is provided.

In such a configuration, the operator can
The operation of the CPU 1 when power is supplied to the CR will be described with reference to the flowchart of FIG. When the operator turns on the power to the ECR, the CPU 1 proceeds to step S
The process proceeds to A1, and it is determined whether the sensor S1 is on. If the result of this determination is "YES", then step S
Proceed to A2.

In step SA2, the control program B in the control program B area 8b of the ROM 8, that is, the control program B when the barcode scanner 25 is used, is selected, and then the process returns to the main routine.

On the other hand, if the result of the determination in step SA1 is "N
If "O", that is, if the sensor S1 is off, the process proceeds to Step SA3.

At Step SA3, it is determined whether or not the sensor S2 is ON. If this determination is "YES", the flow proceeds to step SA4.

At Step SA4, after selecting the control program A in the control program A area 8a of the ROM 8, that is, the control program A in the case of using the measuring section 10, the process returns to the main routine.

On the other hand, if the result of the determination at step SA3 is "N
If "O", that is, if both the sensors S1 and S2 are off, the process proceeds to step SA5.

At step SA5, an alarm is issued to the effect that neither the weighing section 10 nor the barcode scanner 25 is connected to the storage recess 12, and then the process returns to the main routine.

In the above-described second embodiment, an example in which the sensors S1 and S2 are provided has been described.
Instead of S2 and S2, a program selection switch may be provided on the printed circuit board stored in the ECR main body, and this switch may be switched according to the device attached to the storage recess 12 by the operator. Hereinafter, the operation of the CPU 1 when the operator turns on the power to the ECR will be described with reference to the flowchart of FIG. This EC
When power is supplied to R, the CPU 1 proceeds to the process of step SB1 and determines whether or not the program selection switch is on the side for selecting the control program A. If the result of this determination is "YES", the flow proceeds to step SB2.

In step SB2, after selecting the control program A in the control program A area 8b of the ROM 8, that is, the control program when the measuring section 10 is used, the process returns to the main routine.

On the other hand, if the result of the determination in step SB1 is "N
If "O", that is, if the program selection switch is not set to select the control program A, the process proceeds to step SB3.

At step SB3, after selecting the control program B in the control program B area 8a of the ROM 8, that is, the control program when the barcode scanner 25 is used, the process returns to the main routine.

In the above-described second embodiment and the case where the program selection switch is provided, the example in which the CPU 1 automatically selects the control program is shown. It is determined whether or not the device accommodated in the concave portion 12 matches,
If they do not match, an alarm may be generated.

By the way, the ECR described above includes a display unit 2
A dot display is used. Further, as shown in FIG. 3, a part of the operation unit 3 is configured as a touch key 4 provided on a dot display screen of the display unit 2.

Therefore, as described above, when the control program is switched, only necessary displays can be displayed according to the switching, and only necessary keys can be provided.
For example, when the barcode scanner 25 is used, the display column dedicated to the weight and the “zero” key and the “tare” key related to the weighing unit 10 are unnecessary.

In the above-described embodiment, an example in which the present invention is applied to a single ECR is shown.
(Point-Of-Salse: Point-of-sale information management) The present invention may be applied to a terminal device used in a system. That is, in this specification, the electronic cash register includes a terminal device for a POS system.

[0058]

As described above, according to the present invention,
Since the ECR main body and the electronic scale are integrally configured, there is an effect that the device can be downsized. Therefore, there is no inconvenience even if the ECR is arranged in a limited space such as the upper surface of the showcase.

Further, since the ECR main body and the electronic scale are integrally formed, a connection cable is not required, and an operator or a customer can hook the foot or hand on the cable to damage the connector portion or drop the electronic scale or the ECR. There is no danger of being caused.

Further, by replacing the electronic balance with a barcode scanner, an electronic cash register having a built-in barcode scanner can be easily configured.
