Description

[Detailed explanation of the invention] This invention is a price calculation scale that calculates the price of the object to be weighed from the set unit price and weight value, and in particular, the three setting items of the set unit price, set weight value, and set price are combined into one label. Regarding the charge calculation scale with a printing device that has a setting item printing mode that allows printing, the purpose is to prevent printing of incorrect labels in the setting item printing mode, and to improve the reliability of the charge calculation scale with the printing device. The goal is to ensure sex.

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 shows an outline of the configuration of a price calculation scale with a printing device. 1 is a scale body, which has a load cell and an analog-to-digital converter, and outputs a digital signal Dg according to a load value. 2 is a microcomputer section which calculates the price of the object to be weighed and processes various set values based on various input information to be described later. 3 is a numeric keypad as an input device, 4 is a mode setting switch, which sets the microcomputer section 2 to a normal operation mode in which the price of the object to be weighed is calculated from the set unit price and weight value; For example, a unit price setting mode, a weight setting mode, and an amount setting mode, which selectively allocate the set weight and the set amount, respectively, and a setting item printing mode, which prints the three setting items on one label, can be selectively selected. It consists of a changeover switch with five selection positions. Reference numeral 5 denotes a memory for storing various data, in which the numbers keyed in via the numeric keypad 3 are stored in numerical sequences of unit price, set weight, and set amount when unit price setting mode, weight setting mode, and amount setting mode are selected by mode setting switch 4. It is configured so that it can be stored as 6 is a printing device consisting of a label printer, and 7 is a display device.

2 and 3 are explanatory diagrams of the operation of the microcomputer section 2 when the mode setting switch 4 is located in the normal operation mode and the setting item printing mode selection position, respectively.
11 is a weight display section, a unit price display section, and a price display section that constitute the display section; 11 is a price calculation section; D _G , D _A ,
D _M are set weight data, set unit price data, set amount data, and 1 read out from memory 5, respectively.
2 is an interface for the printing device 6, 13 is an interface for the display section 7, and 14 is a comparison section.

In FIG. 2, the price calculating section 11 includes the weighing section body 1.
The output digital signal Dg and the set unit price data D _A are input, and the price calculation unit 11 calculates the price Dm of the object to be weighed according to the weight value.
The digital signal Pg, set unit price data D _A , and calculated object price Pm are input to 2 and 13, and the printing device 6 issues a printout when the weighed values are balanced by the interface 12 or from outside. When instructions are given, set weight, unit price, and price to 1
Print on one label. In addition, the weight display section 8, the unit price display section 9, and the price display section 10 each display the weight, which is printed on the label via the interface 13.
Unit price and price are displayed digitally.

In FIG. 3, set weight data D _G , set unit price data D _A , and set amount data D _M are input to the interfaces 12 and 13, and the price calculation unit 11
is the set weight data D _G instead of the digital signal Dg.
is input, and the comparison unit 14 compares the correct price Dm of the object to be weighed calculated from the set unit price data D _A and the set weight data D _G in the price calculation unit 11 with the set amount given by the set amount data D _M. death,
Only after a match is detected, the interface 12 is instructed to enable printing, and when a mismatch is detected, at least a predetermined item out of the three items [for example, one or two of the three items, such as the set amount, or 3 items] is prohibited from printing.

FIG. 4 shows a flowchart of the microcomputer section 2 when the mode setting switch 4 is located at the setting item print mode selection position. When a printing instruction is given, first the set weight,
Check [a-1] that the set values for the three items of set unit price and set amount are not zero, and if they are not zero, check that (set weight) x (set unit price) is equal to the set amount [ a-2]. [a-
If any of the amounts is determined to be zero in step 1], or if it is determined to be equal to the set amount in step [a-2], immediately instruct printing [a-3], and also instruct [a-3].
2], if it is determined that the amount is not equal to the set amount, a printing prohibition instruction [a-4] is output.

With this configuration, the microcomputer section 2 automatically prevents the issuance of unreliable labels in the setting item print mode, thereby ensuring the reliability of the issued labels.

In the above embodiment, the correct set amount is calculated from the set weight and the set unit price, and the actual set amount is compared with the calculated correct set amount, but the set weight, set unit price, and set amount are It may also be configured to compare the correct setting value of the remaining one item determined from two of the items with the actual remaining one item to determine whether or not printing is possible.

Further, in the above embodiment, when the comparison unit 14 detects a mismatch, the printing operation of the predetermined item by the printing device 6 is only prohibited. It is also possible to notify the outside. The notification means may be a buzzer, a lamp, a means for flashing the display contents of the display section 7, or the like. Further, in the above embodiment, the mode setting switch 4 was explained as having five positions including the setting item printing mode, but it is located in any one of the unit price setting mode, weight setting mode, and amount setting mode. It can also be configured to automatically enter the setting item print mode when the setting operations for the three items of weight and set amount are completed.

As explained above, according to the present invention, the set weight,
Setting unit price and setting amount can be printed and issued In the setting item print mode, calculate the correct setting value of the remaining one item from two of the three setting items, compare it with the actual setting value of the one item above, and make sure that both are the same. Since the label is configured to prohibit printing of a predetermined item out of the three items if the label does not match, the reliability of the printed label can be sufficiently ensured.

Claims (1)

[Scope of utility model registration request] There is a normal operation mode in which the price of the object to be weighed is calculated from the set unit price and weight value, and the price of the object to be weighed is printed and issued.Also, the three setting items of the set unit price, set weight value, and set price can be printed and issued on one label. In a price calculation scale with a printing device that has a setting item printing mode, in the setting item printing mode, the correct setting value of the remaining one item is calculated from two items of the setting unit price, setting weight, and setting amount, and the actual setting value is calculated. The printing device is characterized in that it is configured to compare the setting value of the remaining one item with the calculated correct setting value, detect a mismatch between the two, and prohibit printing of a predetermined item among the three items. Price calculation scale.
