Abstract

PURPOSE:To perform a correcting operation efficiently by providing a memory means storing the contents such as name of an item, weight, unit price and total price, a display means, a selecting means and a correcting means. CONSTITUTION:It is assumed that the contents displayed at present are name of an item 'HAM', weight 400g, unit price 40 yen and total price 160 yen, for instance. When a cursor key 19 is pushed on the occasion, a scrolling-back correction mode flag is set at '1'. Then, an address pointer 35 is shifted to a home position, i.e. the position of 'HAM', and the name of the item 'HAM', the weight 400g, the unit price 40 yen and the total price 160 yen stored in a registering memory 38 and indicated by the address pointer 35 are outputted to a display output control circuit 37 and returned. When a correction key 22 is pushed then, it is checked whether the scrolling-back correction mode flag is set at '1' or not, and when it is set at '1', the name of the item 'HAM' and others displayed at present are cleared. In this way, a correcting operation is performed efficiently.

Description

[Detailed description of the invention] Industrial applications The present invention is installed in one store, with one product name, one weight, and one price.

This invention relates to an electronic price scale that can display product details such as price and add registration.

Conventional technology In conventional electronic price scales, when calling up the product to be corrected in order to correct the product details such as the product name 9 weight, unit price, price, etc. that have already been registered, the PL of the product to be corrected is required.
The product item is called up using the U (Price LookTJp) number.

Problems to be Solved by the Invention Therefore, if corrections were made one by one using PLU numbers as in the past, the operator himself would have to know which product and which PLU number.
It is very inconvenient to have to remember whether each product corresponds to the LO number, and if two or more products with the same PLU number are registered, corrections must be made to the last registered product. It can only be done for things that are.

Means for Solving the Problems In order to solve these problems, there is a storage means for storing the contents of each product item, a display means for displaying the stored contents, and a display means for displaying the displayed contents. It is provided with a selection means for changing by scrolling in the recording order or in the reverse direction, and a correction means for correcting the selected contents by operating a key.

The contents of the product items stored using the action storage means are displayed and confirmed using the display means, and the displayed contents can be changed in the order of registration or in the reverse direction by operating keys using the selection means. The user scrolls to make changes, and uses the correction means to correct the desired product item by operating keys.

to move to.

Also, reading of the registration mode changeover switch 6 is OFF.
If F, read the scale data, process the scale data, make the display blink after 16 seconds have passed from the start, read the depth switch 30 again, read the registration mode changeover switch 6, and then is O
If it is FF, the scale data is read and the scale data is processed.

Further, if it is not OFF', the display and blinking of 8 is repeated to check the segments of the weight display 12, unit price display 13, and price display 14 described above. and,
When the scale data becomes stable as described above, the zero range is checked, a power failure is detected, and the process moves to MAIN in FIG. 8.

Next, in Figure 8, after checking the mode,
A front switch check is performed and the OFF state of the registration mode changeover switch 6 is checked. If it is OFF, it returns to the ``○FFJ'' position shown in Figure 7, but if it is not OFF, it checks to see if there is a key.If there is a key, if it is a front key, it returns to the ``Front key processing'' shown in Figure 9 (described later). ”, performs remote key processing if it is not a front key, and then displays the lamp and display.

Check again for the presence of the key.

If there is no key, the balance data is read, scale data processing and auto-zero processing are performed, and then the OFF state of the registration mode changeover switch 6 is checked. And O
If it is FF, it will return to the rOFFJ position shown in Figure 7, but

Then, check whether net calculation is necessary or not, and if it is necessary, calculate the gross, auto clear,
Calculate the net weight and check the auto clear conditions.

It also checks whether price calculation is necessary, calculates the price if necessary, rounds the price value according to certain conditions, displays the lamp and prints the label, and prints the MAI.
Return to the beginning of N.

"Front key processing" in such an operation will be explained based on FIG. 9. First, the currently displayed contents are product name rHAMJ, weight 400g, unit price 4 in Figure 1.
Assume that the price is 0 yen and the price is 160 yen. At this time, when the cursor key (-) 19 is pressed, the scrolling back correction mode flag is set to "1". Then, the address pointer 35 is moved to the home position, that is, the position of rHAMJ in FIGS. 1 and 2, and the product name rHAMJ, weight 400, and
g, unit price: 40 yen, price: 160 yen, and return.

Then, when the correction key 22 is pressed, it is checked whether the scrolling correction mode flag is set to "1" or not. If it is set to "1", the currently displayed product name rl-IAMJ, weight Clear 400g, unit price 40 yen, price 160 yen, perform initial display and return. Thereafter, corrected data is input as necessary. If the scrolling back correction mode flag is not set to "1", the process moves to other processing.

Next, assume that the currently displayed contents are the product name rHAMJ, weight 400 g, unit price 40 yen, and price 160 yen in FIG. 1, which is the same as described above. At this time, when the scroll key (upper) 20 is pressed, it is checked whether the scrolling back correction mode flag is set to "1", and if it is set to "1", the address pointer 35 is moved to rHAMJ. Move it toward the upper rCHICKENJ position. However, if it reaches the rB E E FJ position, move it to the lower rHAMJ position.

After that, the product name rCHI of the registration memory 38 indicated by the current address pointer 35 is sent to the display output control circuit 37.
CKENJ, weight 200g, unit price 80 yen, price 160
Outputs yen and returns. If the scrolling back correction mode flag is not set to "1", the process moves to other processing.

Then, when the correction key 22 is pressed, the currently displayed product name rCHICKENJ, weight 200g, unit price 80 yen, and price 160 yen are cleared, and other processes similar to those described above are performed.

Next, let us assume that the currently displayed contents are shown in FIG. 1, the same as described above, with product name rHAMJ, weight 400 g, unit price 40 yen, and price 160 yen. At this time, when the scroll key (lower) 21 is pressed, it is checked whether the scrolling back correction mode flag is set to "1", and if it is set to "1", the address pointer 35 is set to "1". Since there is nothing below HAMJ, that is, below rHAMJ in this case, it is moved to the first position rBEEFJ.Then, the product name rBEEFJ of the registered memory 38 currently indicated by the address pointer 35 is sent to the display output control circuit 37. , weight 300g, unit price 200 yen 1. Output the price 600 yen and return. If the scrolling back correction mode flag is not set to "1", proceed to other processing.

Then, when you press the correction key 22, the currently displayed product name rBEEFJ, weight 300g, unit price 200 yen, price 60
0 yen is cleared, and other processing similar to that described above is performed.

Here, descriptions of other processes and other key processes will be omitted, but in this case as well, processes are sequentially performed based on key operations.

In this way, by performing "front key processing", there is no need to call up the registered contents using the PLU number,
Corrections can be made according to the displayed product name.

Effect of the invention As mentioned above, the present invention is based on product name, weight, and unit price.

Since it is equipped with a storage means for storing contents such as prices, a display means, a selection means, and a correction means, the registered contents are sequentially scrolled in the registration order or in the reverse direction to display and confirm the contents. can be done, thereby
Even if two or more identical products are registered, corrections can be made to all of the same products, and furthermore,
Since the operator does not have to remember which product corresponds to which PLU number, the operator can save time and work efficiently.
