Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a unit price setting method in an electronic fare scale that calculates and displays a price from weight data taken in from a weighing unit and a unit price recalled from a unit price preset memory.

Conventionally, in electronic rate scales that use preset unit prices, the unit price is entered and displayed using the numeric keypad, and in this state, by specifying a department using the department key, the unit price is stored in the corresponding unit price preset memory and displayed. There is a known method that clears the information and waits for the next unit price setting.

However, in this unit price setting method, the display disappears as soon as the department key is operated, so the previously set unit price cannot be confirmed when setting the next unit price, resulting in poor operability.

This invention was devised in order to eliminate these drawbacks, and is an electronic price scale that can improve operability when setting unit prices by confirming the previously set unit price before setting the next unit price. The purpose is to provide a unit price setting method for

Next, the processing performed by the data processing section 34 will be described based on the flowcharts of FIGS. 8 to 15. FIG. 8 is the main flowchart, and when the power is turned on to start, 1 initialization processing is performed. In this initial processing, RAM clearing, etc. are performed. 2.Subsequently, a power outage process is performed, and then a 3-display scan is performed to check each digit segment of each display 6, 7, 8, and 9. When this display scan is completed, DPKF
and starts reading the status of 4. In this status reading, the mode state of the mode changeover switch, ie, one of "registration", "setting", and "accounting" is read according to the states of REGH and SETH. In addition, the ARTLB checks whether the switch switches 26, 27, and 28 for single item label issue/prohibition, measurement label issue/prohibit, and subtotal label issue/prohibit are set to "issuance" or "prohibition".
Read according to the status of MESLB and STLB. 5 Next, set processing for each mode is performed. This sets or resets the mode flags SETF and INQF depending on the state of the mode changeover switch read in step 4, and performs initial display. If the process of step 5 is shown in a flowchart, as shown in FIG. 9, it is checked whether SETH=1 or not, and if SETH=1, it is determined whether REGF=1 or not by flag determination in 5-1, and REGF=1. If so, it will be the end, but if REGF≠1 then continue
It is checked whether SETF=1 or not, and if SETF=1, it is determined that the setting mode was used last time, and the process ends. If SETF≠1, the initial display of the setting mode is performed at 5-2, and SETF is set to "1" at 5-3, and the process ends. On the other hand, SETH
If ≠1, then it is checked whether REGH=1 or not, and if REGH≠, flag determination of 5-4 is performed. In this flag judgment, for example, it is judged whether REGF = 1, and if REGF = 1, it is the end, but REGF
If ≠1, then it is checked whether INQF=1 or not, and if INQF=1, it is determined that the previous payment mode was also used, and the process ends. Also, if INQF≠1, initial display of payment mode is performed at 5-5, and 5-
At 6, INQF is set to "1" and the process ends. Furthermore, if SETH≠1 and REGH≠1, then 5-
At step 7, both SETF and INQF are reset and the process ends. In this manner, in the setting process for each mode of 5, when SETH=1 and REGH≠1, reading is performed as a setting mode, and if SETF is not set, it is set. Also, SETH≠1,
When REGH≠1, reading is performed in settlement mode, and if INQF is not set, it is set. Also, when SETH≠1 and REGH=1, reading is performed as a registration mode and both SETF and INQF are reset. When the setting processing for each mode in step 5 is completed, it is then checked whether or not a key-in has occurred, and if there is a key-in, key processing in step 6 is performed.
If there is no key-in, read ADC data at 7,
That is, count data is read from the A/D converter 33 of the weighing section 30 via the data selector 37.
Subsequently, flicker processing is performed at step 8, and auto-zero processing is performed at step 9 to determine the true value of the weight. That is, the processes 7, 8, and 9 are a well-known series of processes performed by reading count data corresponding to the weighing value from the weighing section 30. When this series of processing is completed, check whether it is in registration mode with SETF and INQF, and if it is not in registration mode, return to 4 to 9.
Repeat the process. Registration mode i.e. SETF
If ≠1 and INQF≠1, the automatic measurement display recovery process of 10 is performed. This automatic weighing display restoration process checks whether the display is fixed after registration.
When the device is fixed, the weight is checked and automatically entered into weighing mode (mode that allows registration by weighing).
Perform processing to return to . Also, when the conditions for returning to the weighing mode are satisfied, the DSPHF is reset. FIG. 10 is a flowchart showing this automatic measurement display return process, in which first it is checked whether DSPHF=1 or not. And when DSPHF≠1, DSPHF is 10-1,
Reset DSPRF and end this process.
When DSPHF=1, it is subsequently checked whether DSPRF=1 or not. If DSPRF≠1, after registration, the product and tare are removed from the weighing platform 1 and a check is made to see if the gross weight has become zero or less.
If the gross weight has not become zero or less, this process ends. Also, if the gross weight becomes zero or less, DSPRF is set at 10-2. Furthermore, if DSPRF=1 is determined in the above, it is determined that the gross weight has become less than zero after registration, and then it is checked whether the gross weight has become more than 20 g. If the gross weight is 20 g or more, DSPHF and DSPRF are reset at step 10-1 and the process is automatically returned to the weighing mode. In this way, in the weighing display automatic return process in step 10, if DSPHF is set, it is determined that it has been registered, and in this case, if the gross weight once falls below 0g and then exceeds 20g, it will automatically return to the weighing mode. Process. When this weighing display automatic return process is completed, the net weight is calculated by subtracting the weight and calculating the tare weight at step 11. Next, in step 12, the price is calculated by multiplying the net weight by the unit price. When this is completed, check whether DSPHF=1 or not.
If DSPHF=1, it is determined that the display is fixed after registration, and the process returns to the above. If DSPHF≠1, it is determined that the weighing mode is in effect, and various status lamps are set at step 13, namely, a power failure/error lamp 10, a zero point lamp 11, and a tare weight setting lamp 1.
2. Selectively light up the total lamp 13, etc. Next, at step 14, the unit price, weight, price, and tare display data are subjected to zero suppression processing, and at step 15, these display data are displayed on the various displays 6, 7, 8, of the display device 4.
Display it on 9. When this display processing is completed, it is subsequently checked whether AUTF=1 or not, and it is determined whether the automatic label issuing mode is set. and
If AUTF=1, it is determined that the automatic label issuing mode is set, and then a flag determination is performed in step 16. This flag determination checks, for example, ENAF, which is set when the weight is stable, and MINCF, which is set when the weight is 20 g or less, to determine whether or not it is possible to issue a label. When it is determined that it is okay to issue a label, 1
At step 7, automatic label issuance processing is performed and the process returns to the above. Further, if it is determined that the label cannot be issued by the flag judgment, or if AUTF≠1, the process returns to the above without performing the label issuing process.

By the way, various processes are performed by operating various keys in the above-mentioned 6 key processes, and the main key processes will be described below. First, Figure 11 shows "0" to "9"
In the flowchart for the numeric keypad 16 and erase key 18, when the numeric keypad 16 is operated, it is first checked in 6-1 whether or not the numeric keypad 16 can be operated, depending on whether INQF=1 or not. judge. When INQF≠1, it is determined that the numeric keypad 16 can be operated and further resets DSPHF. Also, when INQF=1, it is in the payment mode and no reception is made using the numeric keypad 16, so the process ends immediately in this case. When the DSPHF reset process is completed, the data input using the numeric keypad 16 is stored in the NREG (number register) at 6-2.
Store in. Then, it is checked whether SETF=1 or not, and if SETF≠1, then it is checked whether DPKF=1 or not. And if DPKF=1 then 6-
After setting the PNF in step 3, in step 6-4
Store the contents of NREG in DATAM (U) as unit price data. Also, if DPKF≠1, immediately 6-
Go to 4. When the storage process in 6-4 is completed, the routine moves to the process shown in FIG. Above, SETF≠
When the numeric keypad is input in step 1, the data is stored in DATAM (U) as unit price data.
On the other hand, when SETF=1, it is subsequently checked whether SETCF=1 or not. Then, when SETCF≠1, it next checks whether DPNO=0 or not, and DPNO
When ≠0, use the contents of NREG as the unit price in 6-5.
It is preset to the PLU corresponding to the contents of the DPNO, and further displayed on the unit price/point display 8 in step 6-6.
Also, if SETCF=1, then check whether DPNO=0 or not, and if DPNO≠0, in 6-7
Preset the contents of NREG as a code to the CORD of the departmental total memory corresponding to the contents of DPNO,
The price is displayed on the price display 6 at 6-6. And 6-
When the display process of 6 is completed, this numeric keypad process ends. Further, in the above case, when DPNO=0, this ten key processing ends immediately. SETF=
When the numeric keypad is input in 1, further
Check SETCF, and if SETCF=1, the data will be preset to CORD as a code, and if SETCF≠1, the data will be preset to PLU as a unit price.

On the other hand, when the erase key 18 is operated, at 6-8
Reset DSPHF, then NREG at 6-9
Clear and check whether SETF=1.
If SFTF=1, then it is checked whether SETCF=1 or not. If SETCF≠1, the process of 6-5 is performed, and if SETCF=1, the process of 6-7 is performed. Moreover, if SETF≠1, the process of 6-4 above is performed and the process goes on.

FIG. 12 is a flowchart regarding the wind key 17. When the wind key 17 is operated, a flag is first determined at 6-10. This flag judgment is to check whether wind keys can be accepted.For example, SETF,
Check whether INQF and DSPHF are all reset. If even one is set, it is determined that the wind key 17 cannot be accepted, and the 8th
Immediately move the routine to the one shown in the figure. Also 6-
SETF, INQF,
When it is determined that all DSPHFs have been reset, it is then checked whether ENAF=1 or not. That is, ENAF is a flag that is set when the weight data is stable, with fluctuations within one scale, for example, so this is used to check whether the weight data is stable. and ENAF
If = 1, then it is checked whether MNSCF = 1 or not, and it is checked whether the weight has become a negative count value. Then, if MNSCF≠1, check whether weight = 0 or not. This checks whether there is nothing on the scale stand 1 and the zero point lamp 11 is lit. If the weight is 0, then it is checked whether the unit price is 0 or not. This is done by checking whether the contents of DATAM(U) are zero. Then, when weight≠0 or when weight=0 and unit price=0, it is checked whether the weight data is within three digits, that is, the number of digits for taring. and 3
If it is within the digits, use 6-11 to set the weight as a tare amount.
The data is stored in TARE, and the routine moves to that shown in FIG. Also, when the wind key 17 is operated, ENAF=
1, ENAF=1 and MNSCF=1, ENAF=1
MNSCF ≠ 1, weight ≠ 0, weight 4 digits or more, or
ENAF=1, MNSCF≠1, weight=0, unit price=0
6-12 if the weight is in each state of 4 digits or more.
At step 6-13, TARE and NTARE are cleared, and at step 6-13, DATAM(U) is cleared, and the routine proceeds to step 6-13. Further, in the above case, when the unit price≠0, it is checked whether the unit price is within three digits. If the unit price is within three digits, it is then checked whether the numerical value of the unit price is a multiple of the minimum weight scale. If the value of the unit price, that is, the content of DMTAM (U), is in the relationship of multiples of the minimum weight scale, then in 6-14
The unit price of DATAM (U) is stored in NTARE as a tare amount, and the process moves to clear DATAM (U) in 6-13 above. In addition, if the unit price is not within 3 digits in the above, or if the unit price is within 3 digits but not a multiple of the minimum weight scale, please refer to 6-12 above.
Move on to clearing TARE and NTARE.

FIG. 13 is a flowchart for department key 15.
When the department key 15 is operated, the department number is first set to DPNO in step 6-15. Then, it checks whether SETF=1 or not, and if SETF=1, it is determined that it is a department key operation in the setting mode, and 6-1
The department number, preset unit price, and code stored in DPNO are displayed at 6-16'.
to reset SETCF and end this key processing. Also, if SETF≠1, then it is checked whether INQF=1 or not. If INQF≠1, DPKF and PNF are reset in 6-17.
Then check whether DPNO=32. and
If DPNO≠32, set AUTF in 6-18, then correspond to the contents of DPNO in 6-19.
Load PLU (LORD) and read it to DATAM (U). When this process is completed, the routine shifts to that shown in FIG. Also, when DPNO = 32, it is determined that the operation is a department key dedicated to pack pricing, and 6
-18 is passed and the process moves to 6-19. If INQF=1 in the above INQF check, the department number is displayed at 6-20 and the department total is displayed. This is determined to be a department key operation in the settlement mode, and the department number of the DPNO and the total points, total weight, and total price of the department total memory corresponding to that department number are displayed. 6 more
At step -21, the contents displayed at step 6-20 and the department code are printed on a label and issued, and the process ends.

FIG. 14 is a flowchart for the single item key 19 and the scale addition key 20.
At step -22, a flag is determined as to whether or not a single key can be accepted. For example, this flag judgment is
This is performed depending on whether SETF, INQF, and AUTF are all reset, and if they are all reset, it is determined that the operation of the single item key 19 is in the single item label issuing mode, and then ARTF is displayed in 6-23 to indicate the single item mode.
and resets MESF indicating the scale addition mode. Furthermore, if any one of SETF, INQF, and AUTF is set, this key processing ends immediately. After the process of 6-23 is completed, continue
Check whether PNF = 1 or not, and if PNF = 1, select the single item open department number at 6-24, for example "3".
1" is set in DPNO. If PNF≠1, the process of 6-24 is passed. Next, it is checked in the state of ARTLB whether the single item label is set to issue or is set to prohibit issue. Then, if it is set to be able to issue a single item label, the single item label is issued at 6-25.If the prohibition of issuing a single item label is set, the process at 6-25 is passed.Subsequently, at 6-26 Displays the department number, adds the unit price to the single item memory, displays it in the price column, and also adds the number of individual items.
1 and display. Further, in 6-27, the unit price is added to the price subtotal memory, STP, price PT of the department total memory corresponding to the department number, and price total memory GTP, respectively. When the processing of 6-27 is completed, it is checked whether PNF=1 or not, and PNF
If ≠1, DPKF is set at 6-28,
If PNF=1, the process of 6-28 is passed.
Furthermore, it is checked whether MESF=1 or not.
And if MESF=1, DATAM at 6-29

Set DSPHF at , and finish this key processing.

On the other hand, when the scale addition key 20 is operated, the
Check whether SETF=1. and SETF
If =1, it is determined that the scale addition key has been operated in the setting mode, SETCF for switching from unit price setting to code setting is set at 6-31, and this key processing is terminated. Also, if SETF≠1, a flag is determined in 6-32 to determine whether or not the weight value is stable, and if it is determined that the weight value is stable, 6-3
Set MESF and reset ARTF in step 3. Then, check whether PNF=1 or not. If PNF=1, then in step 6-34, the department number for metering open, for example "30", is set in DPNO. Further, if PNF≠1, the process of 6-34 is passed. Next, check whether the weighing label is set to issue or not to issue using MESLB.
Check the condition. If the weighing label is set so that it can be issued, the weighing label is issued at 6-35. Furthermore, if the prohibition of issuance of weighing labels is set, the process of 6-35 is passed. Next, at 6-36, the contents of the DPNO, that is, the department number, and the calculated price are displayed. Furthermore, in step 6-37, the weight and price are added to the subtotal, department, and grand total memories. Then, it is checked whether PNF=1 or not, and if PNF≠1, the above-mentioned process 6-28 is performed.

FIG. 15 is a flowchart for the total key 21,
In this key operation, if INQF≠1, subtotal memory (STP)=0, and unit price (DATAM(U))≠0, flag determination is performed in 6-38. This flag judgment is, for example, SETF≠1, AUTF≠1, ENAF=
This is done depending on whether the label is set to 1 or not, and only when each flag is set in this way, it is subsequently checked in the MESLB state whether the weighing label is set to be issued or prohibited. If the setting is such that the weighing label can be issued, the weighing label is issued at step 6-39. Further, if the prohibition of issuance of weighing labels is set, the process of 6-39 is passed. Next, at 6-40, the department number of the DPNO is displayed, the price after calculation is displayed, and the total lamp 13 is turned on. Subsequently, at 6-41, the registered data of weight and price are added to the department total memory and the total total memory. And at 6-42 DATAM
The unit price of (U) is cleared, and DSPHF for display fixation is set at 6-43, and this processing is completed. Further, in the above case, when INQF≠1, subtotal memory (STP) = 0, and unit price = 0, it is further checked in STLB whether the subtotal label is set to be issued or prohibited. If the subtotal label is set so that it can be issued, the subtotal label is issued at 6-44. Further, if the prohibition of issuing subtotal labels is set, the process of 6-44 is passed. followed by 6-45

The total lamp 13 is turned on. Furthermore, in 6-46, the subtotal memory is cleared and the process proceeds to 6-42. Also, in the above, INQF≠1, subtotal memory≠
If it is 0, it is further checked to see if ARTF=1 to see if a single item was registered last time. and
When ARTF=1, it is then checked whether it is a subtotal score or not. And when ARTF≠1 and ARTF=
1 and the subtotal score≠1, the process moves to subtotal label issuance processing. Further, when ARTF=1 and subtotal score=1, the department number is displayed, the individual item memory is displayed, and the total lamp is lit at 6-47, and the process moves to 6-46. In addition, when INQF = 1 in the above, it is determined that it is in the settlement mode, and the contents of the total memory (GTW, GTP) are displayed at 6-48, and the total displayed at 6-49 is printed. The label is issued and the process ends.

With such a configuration, if you want to preset the unit price and code, set the mode changeover switch to the "setting" mode and set SETH=1. This allows SETF
is set. In this state, the department to be preset is first specified using the department key 15. With this department designation, the department number is stored in the DPNO and is displayed on the department/tare display 6. At the same time, the corresponding PLU is designated by the department number and its contents are displayed on the unit price/point display 8. Therefore, if the PLU contains a previously preset unit price, it will be displayed, and if nothing has been preset in the PLU, zero will be displayed. At the same time, the corresponding departmental total memory is specified by the department number, and the code preset memory for that total memory is specified.
The contents of the CORD are displayed on the price display 9. Furthermore, SETCF is reset. In this state, when a unit price to be preset is entered using the numeric keypad 16, that unit price is stored in the PLU specified by the department number, and its contents are displayed on the unit price/point display 8.
will be displayed. Subsequently, when the scale addition key 20 is operated, SETCF is set. In this state, when a code to be preset is entered using the numeric keypad 16, the code is stored in the CORD of the departmental total memory designated by the department number, and its contents are displayed on the price display 9. Both indicators 8,
The display of the unit price and code by 9 will continue until the department key is operated to preset the next unit price and code. Therefore, when starting the next preset, the previously preset unit price,
Since the contents of the code can be checked, the next preset operation can be carried out smoothly and operability can be improved.

In addition, in this embodiment, when the numeric keypad 16 is operated without operating the department key, DPNO=0.
Therefore, preset processing is not performed.

As described in detail above, according to the present invention, the electronic system reads weight data from the weighing section, calculates the price by calling up the unit price from the corresponding unit price preset memory using the department key, and displays the weight, unit price, and price, respectively. When presetting a unit price in the unit price preset memory on a price scale, first operate the department key to display the contents of the corresponding unit price preset memory, and in this state, operate the numeric keypad to preset the unit price. Since the unit price is preset in the set memory and the preset unit price is displayed, the previously set unit price can be displayed until the next unit price preset is started, improving the operability of unit price setting. It is possible to provide a unit price setting method for an electronic fare scale that can be used.
