Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic fare scale with a message display installed at a store so that customers on the front side and clerks on the back side can recognize the contents of the message.

BACKGROUND TECHNOLOGY In general, in this type of electronic fare scale with a message display, the remote display unit is configured with a store-side display and a customer-side display placed on the front and back. Since the same control circuit is used for the side display and the customer side display, the same content is displayed.

The pressure point electronic fare scale that the invention seeks to solve has a built-in electronic circuit that displays messages to guide the clerk's operations and messages to point out erroneous operations.

For example, a message such as ``Please enter the product number'' or ``The number is incorrect.'' may be displayed.
The contents of such a message are displayed not only to the clerk but also to the customer at the same time. Therefore, the display is unnecessary and bothersome to the customers, and in some cases may cause them to feel uneasy or uncomfortable.

Means for solving the problem Separate control circuits are formed to set the display contents of the customer-side display and the surrounding-side display.

Effect: As mentioned above, when a message unnecessary for the customer is displayed, the message is displayed only on the shop side, and a different content is displayed on the customer side display.

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

A changeover switch 6 is provided. Further, a support 7 is erected from the back side of the main body case 2, and a remote display unit 8 is attached to the upper end of the support 7. This remote display unit 8 is provided with a peripheral display 9 and a customer display 1o on the front and back sides, respectively. The peripheral side display 9 and the customer side display 10 of the remote display unit 8 have the same structure as shown in FIG.
A message display 11 is provided around which characters such as "Jr. Score" are arranged. This message display device 11 is capable of displaying characters, symbols, and drawings using a 176×16 dot matrix. Further, below it, a weight display 12, a unit price display 13, and a price display 14 are arranged by seven segments such as a Nixie tube.

Next, the front key panel 5 has direct keys 1 to 99 that call up the product name directly,
In addition to the numeric keys 9 to 9, there are also paper feed 1 key, paper feed 2 key,
Test key, zero setting key, setting key, effective date key, next part number mode key, auxiliary key, fixed price key, date key, number of packs key, correction key, number of pieces key, discount key, multiplication key,
Addition key, product number key, tare/tare setting key, deletion key,
It has deposit/cash keys, execution keys, etc.

Further, the registration mode changeover switch 6 is set to a setting mode,
It can be switched to registration mode, lock mode, inspection mode, J'1'7 calculation mode and OFF.

Furthermore, a selection switch 15 is provided for selecting whether the operation is performed automatically or manually.

Next, the internal electronic circuit will be explained based on FIG.

First, a load cell 16 for measuring weight is connected to a CPU (central control unit) 18 via an analog-to-digital converter 17. I10 block 19 for the second CPU18
is connected.

The I10 block 19 is connected not only to a depth switch 20, a thermal printer 21, and the registration mode changeover switch 6, but also to an inline interface 22 that is connected to other devices. The CPU 18 also includes a display block 23 including a control circuit.
is connected. The front key panel 5 and the remote display unit 8 are connected to the display block 23. In particular, the weight display 12, the unit price display 13, and the price display 'a14 include a peripheral display 9 and a customer display 10.
The same circuit is used for both, but a separate control circuit is used for each message display 11 of the peripheral side display 9 and the customer side display 10 so that the display contents can be controlled separately. are connected.

The operation of such a configuration will be explained based on a flowchart. First, in FIG. 5, at the start, the memory is cleared, I10 is initialized, and the depth switch 2o is read. Then, the registration mode changeover switch 6 is read to check whether it is in the OFF position.

Here, if it is not OFF, the display of O to 9 and the light off are repeated to check the segments of the weight display 12, unit price display 13, and price display 14, and when the scale data becomes stable, it is zero gf! , check the box, detect a power outage, and move to MAIN in Figure 6.

Also, if it is OFF when reading the registration mode changeover switch 6, read the scale data, process the scale data, turn off the display after 16 seconds have passed from the start, and read the depth switch 2° again. ,moreover,
The registration mode changeover switch 6 is read, and if it is OFF, the scale data is read and the scale data is processed.

If it is not OFF, the aforementioned segment check of the weight display 12, unit price display 13, and price display 14 is performed by repeating 8 and turning off the light. Then, as described above, when the scale data becomes stable, the zero range is checked, a power failure is detected, and the process moves to M A IN in FIG.

Next, in Figure 6, after checking the mode,
A front switch check is performed, and after the initial display routine shown in FIG. 7, which will be described later, has passed, the OFF state of the registration mode changeover switch 6 is checked. If it is OFF, the fifth
As shown in the figure, "○ Returns to the FFJ position, but if it is not OFF,
Check for presence of key. If you have the key, please use the 8th key below.
The front key process shown in the figure is performed, and if there is no key, the FF state of the registration mode changeover switch 6 is checked after reading the scale data, processing the scale data, and performing the auto-zero process. If it is OFF, rOF shown in FIG.
Return to the FJ position, but if it is not OFF, read the data from the quartz timer.

The same applies when the front key processing described below is finished, but it checks whether net calculation is necessary, and if it is necessary, calculates the gross, performs auto clear, calculates the net weight, Check auto clear conditions.

It also checks whether price calculation is necessary, calculates the price if necessary, rounds the price value according to certain conditions, performs lamp display and display, prints a label, and returns.

The initial display routine in such an operation will be explained based on FIG. 7. In other words, the registration mode changeover switch 6
If it is OFF, it returns to the rOFFJ position in FIG. 5, and if it is not OFF, it is checked whether it is in the registration mode. If it is not the registration mode, a separate process is performed, although the explanation thereof will be omitted, and if it is the registration mode, the display content "Welcome" is set in the buffer of the customer side display 1o. Further, the display content "Please input the product number" is set in the buffer of the peripheral display 9. Then, the unit price memory is set to rQJ and the process returns.

Next, the front key processing routine will be explained based on FIG. First, when the numeric keys are being input, check whether the displayed content on the peripheral display 9 is "Please input the product number manually."

If "J" is displayed, enter the input number into the store display buffer and return. If "Please enter the product number" is not displayed, "Welcome" will be displayed in the buffer of customer display 1o. Set the display content. Also,
The buffer on the circumferential display 9 says "Please enter the product number.

” Set the display content.

Then, the unit price memory is set to "0" and the process returns.

Next, if the product number key is pressed, the PLU data is loaded into the PLtJ (price lookup) memory, the product name is input into the customer side display buffer, the PLU unit price is input into the unit price memory, and the process returns.

Further, when the erase key is pressed, the display content "Welcome" is set in the buffer of the customer side display 10. Further, the display content "Please input the product number" is set in the buffer of the peripheral display 9. Then, the unit price memory is set to "o" and the process returns.

Furthermore, when the Deposit/Cash Total key is pressed, the display content of "Purchase Total" is set on both message displays 11, the total amount is set thereon, and the process returns.

Then, if the addition key is pressed, the price is added to the total memory and the process returns.

In this manner, the necessary operations are sequentially performed based on the operated keys, although descriptions of other operations will be omitted.

Effects of the Invention As described above, the present invention is provided with a display circuit that separately controls the display contents of the peripheral side display device and the customer side display device, so that the auspicious display and the customer side display are performed completely separately. As a result, necessary matters can be clearly displayed without giving a complicated impression to customers, and the characteristics of the message display can be fully demonstrated.
