Description

[Detailed description of the invention] The present invention relates to a fee display aggregation system.

More specifically, the present invention relates to a price display and aggregation system for a sushi restaurant that displays, for example, how much sushi each customer has eaten and automatically prints out a receipt at the end.

The price for sushi, etc. is fixed if the amount is fixed in advance, but if you eat it one after another at a restaurant, it is common for the price to be added each time.

However, in the latter case, the price is not fixed in advance, and even if the amount of food increases, the customer cannot know the price for each portion, so they may have to eat with a sense of anxiety. There were some inconveniences, such as not being able to eat safely and deliciously.

Furthermore, the price of sushi is often determined by market prices, which is difficult for customers to understand and creates a sense that it will be expensive, which is not favorable for either customers or restaurants.

The present invention eliminates these conventional drawbacks and makes it possible to arbitrarily find out the amount of money to be spent at any time during the trip without having to ask the store.

The purpose is to provide a price display aggregation system.

To summarize the present invention, a plurality of first rate display devices each having a display switch are provided, and a second rate display device and an input key are provided to display the display contents of these display devices on one screen. A set of input/output means is provided, and the clerk enters the amount each time the sales increase using the input key, and the added total amount is displayed on the corresponding first price display on the customer's display switch. It is designed so that it can be confirmed at any desired time by operation.

Embodiments of the present invention will be described below with reference to the drawings.

What is described below is an example of a price display aggregation system for a sushi restaurant, but I would like to point out in advance that the system is not limited to sushi restaurants.

FIG. 1 shows a block diagram of a fee display aggregation system that is an embodiment of the present invention.

In the figure, display device 1, la, which is the first price display device,
, 1b, =ln is composed of a 5-digit LED display, and a maximum of 32 can be set.

These displays are placed around each individual table or individual customer, and are designed to indicate the additional charge for each table or each customer.

Display switch 2, 2. a, 2b, . . . 2n are switches connected to the display control circuits 3, 3a, 3b, .

Therefore, when a customer wants to know the current total amount of charges, he or she can easily check the charges by operating this switch 2.

In addition, a push button switch is used for switch 2.
Since it is displayed only when this switch is pressed, customers can avoid having their rates known to others.
You can casually check prices.

Next, the second price display, CRT4.4a.

Up to five characters 4b, . . . 4n can be set as character display devices, and these are placed in front of each staff member.

Similarly, the CRT 4 includes keyboards 5, 5a, 5b, . . . 5 having numerical keys and other function keys.
n are attached to each, and each board has a CRT 4
The keyboard 5 can be operated while looking at the screen.

The CRT 4 includes display control circuits 6 and 6a.

6b, . . . 6n are connected, and furthermore, the story display control circuit 6 has character generators 7.7a, 7b.

. . 7n, and registers 8, 8a, sb, . . . 8n are connected to the character generator 7, respectively.

As will be described later, the control unit of this system transfers the character code for one line to be displayed on the CRT 4 to the register 8, and then the character generator 7 converts the character code into a character pattern. It looks like this.

Therefore, the contents of the register 8 are updated every time the corresponding number of characters (numbers) is displayed on the CRT 4.

The input keys of the keyboard 5 consist of numeric keys and function keys including a selection key for selecting one from the plurality of displays 1 and a print key for instructing to issue a receipt.The price is entered using the numeric keys on the former. However, the latter function key is used to select the display and issue a receipt.

9.9a, 9b, . . . 9n in the figure are input control circuits for the keyboard 5, which perform operations such as encoding the contents of input keys.

Next, one journal printer 10, which is a printer device, is set in this system and is connected to a control unit via a print control circuit 11.

Print output by the printer 10 is performed by operating the print key on the keyboard 5, and the print content is the amount displayed on the display 1 selected by the selection key on the same keyboard 5, the food and drink tax amount, and the sum of the sum. becomes.

As described above, the input/output section of this system is composed of a display with a switch for customers, a CRT display and an attached keyboard for the counter, and a journal printer for issuing receipts.

By the way, each element of these input/output sections is connected to each interface 12, 13.14 of the control section, and the CPU 1
5 performs input/output data processing.

The control unit basically consists of a CPU 15, a ROM 16, a first RAM 17, a second RAM 18, and three buses that exchange data between these elements, and controls the microcomputer system. is forming.

The CPU'15 is an 8-bit microprocessor such as Zilog's Z-80 or Intel's 8080, and the ROM and RAM1 interfaces are appropriate.

Of these, the RAM 18 is for the counter, ie, stores the display contents of CR and T4, and the RAM 17 is for the customer, ie, stores the additional amount to be displayed on the display 1.

FIG. 2 is a diagram schematically showing the storage contents of the RAM 17.

The NO area in the same figure represents the number of display 1, the number of people area represents the number of customers assigned to each display, that is, the number of customers occupying each display, and the TOTAL area represents the number of customers to date. Shows the total amount of charges.

The RAM 17 stores, for each display 1, the current charges to be displayed on each display 1 and the number of people required for calculating the food and beverage tax, which will be described later.

In the system of this embodiment, up to 32 settings can be made for the display 1, so the capacity of the RAM 17 is selected to correspond to the settings.

The RAM 18 stores the memory contents of the RAM 17 on the CRT 4.
It functions as a buffer memory for display on the CRT 4, and its storage state is geometrically one-to-one correlated with the display screen of the CRT 4.

Next, the ROM 16 is a memory that stores the processing procedures performed by the CPU 15, and the main control contents in this system are shown in FIG. 3.

The details of this control will be explained below with reference to the same figure.

As mentioned above, the flow shown in the figure shows the main control contents in this system, and the instructions for each step are actually programmed by an instruction set determined by the CPU 15.

These specific programming methods can be easily performed by those skilled in the art, and therefore will not be described in detail here.

First, in step n□ (hereinafter step ni will be simply abbreviated as ni), the display 1 outputs display data of the charges that have been added up to now.

That is, for each display 1, among the storage contents of the RAM 17, the storage contents in the TOTAL area are transferred to the interface 13.
The data is sequentially transferred to each display control circuit 3 via the.

In this case, the display data is not displayed on the display 1 until the customer operates the switch 2, so normally the display data does not reach the display 1 from the display control circuit 3.

Subsequently, at n2, the contents of the RAM 18 are transferred to each register 8 via the interface 14.

The transfer is performed line by line as described above, and the transfer timing is synchronized with the scanning timing of the CRT 4.

Next, nIO determines whether there is an input interruption, that is, an interruption from the keyboard 5.

If there is no interruption in this step, the process returns to the original routine and transfers the display data using nl and n2 again.

Note that since the CRT 4 does not display data unless it is constantly refreshed, it is desirable that the data be transferred directly from the RAM 18 to the register 8, regardless of the processing by the CPU 15.

In this case, it is another element for its control.

For example, a DMAC (direct memory access controller) is used.

Now, if there is an input interruption at nIo, the process proceeds to n2, where the cause of the input interruption is determined.

If the input is to add a new charge, that is,
If the display number and the additional amount, which is the product price, have been input, the process advances to nIa, where the display number corresponding to the customer to whom the addition is to be added is read, and at nIa, the input fee is read.

Next, use n I5 to check the TOTAL of the corresponding RAM 17 area.
Add the loaded charges to the area.

Then, at nIa, the memory capacity of the RAM 17 is rewritten to the RAM 18.

On the other hand, if the display number is input at nI2 and the print key is operated, the process proceeds from nI2 to nl7, and the display number corresponding to the customer to whom a receipt is to be issued is read.

Next, in nl8, TOTA of the corresponding part of RAM17
Read out the charges and number of people in the L area, calculate the food and beverage tax amount from those first shifts, add this to the charges in the TOTAL area, and output the added amount in the next ni9 to the journal printer 10 as the billed amount. do.

In this case, the additional amount and the food and beverage tax amount stored in the RAM 17 are also printed separately.

Input and output control is performed in the manner described above.

Although not shown, the RAM 17 has a capacity that includes, in addition to the area shown in FIG. 2, a storage area necessary to record the total sales for one day.

Further, the entire system is backed up by an uninterruptible power supply 19.

As described in detail above, according to the present invention, in a product purchase format in which a fee is added to each product order and it is difficult for the product purchaser to grasp the additional fee amount, the product purchaser alone can always You can know the prices that have been calculated up to now, and you can obtain an excellent purchasing system that has never existed before.

Therefore, the present invention is suitably applied to the buying and selling of products (sushi) between customers and staff (in front of the restaurant) at a sushi restaurant or the like.
