Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic cash register equipped with a unit price reading device used in department stores, supermarkets, etc.

[Conventional technology]

When changing the unit price of a specific product from a specific time using a conventional electronic cash register equipped with a unit price reading device, as described in Japanese Patent Application Laid-Open No. 63-25796, a file connected to the electronic cash register is used. The controller is equipped with a mask file that stores the unit price for each product code, a unit price change memory that stores the changed unit price for each product code, and a batch processing memory that stores the unit price change time and the product code for which the unit price is changed. When the time comes, the unit price of the product is automatically changed to the changed unit price stored in the unit price change memory.

However, in an electronic cash register equipped with a conventional unit price reading device, the batch processing memory is checked to see if the current time and the changed time match, and if there is a match, the changed unit price in the unit price change memory is sequentially read out, and the changed unit price is read out sequentially. Since the unit price of the corresponding product coat in the mask file is changed, there is a drawback that it takes time to change the unit price when the number of product codes whose unit price is to be changed increases. In particular, if you set a service time and try to sell almost all the products in the store at a certain discount, for example, 10% off from a certain time.
When trying to sell 00 types of products at a discount, the first product whose unit price was changed and 10
If the unit prices were replaced in order with the product whose unit price was changed 00th, a time lag would occur.

As a result, there is a risk that products for which discounts should have started at the same time may end up being sold without being discounted.

[Problem to be solved by the invention]

As mentioned above, with conventional electronic cash registers equipped with a unit price reading device, there is a time lag between the beginning and end of a unit price change. When match information was entered, the unit price of the product that was originally supposed to be discounted had not been changed yet, causing problems such as the unit price before the discount being read out.

SUMMARY OF THE INVENTION In view of the problems of the prior art, it is an object of the present invention to provide an electronic cash register equipped with a unit price reading device that can reliably and efficiently change unit prices.

[Means to solve the problem]

Based on the input of unit price inquiry information including the product code from the registration processing section, the registration processing section reads out the unit price corresponding to the product code from the product data storage means storing the unit price corresponding to the product code. In an electronic cash register equipped with a unit price reading device that outputs
a change time storage section for storing the unit price change time corresponding to the product code; a change unit price storage section for storing the change unit price corresponding to the product code; a clock circuit for measuring the current time; and a clock circuit for inputting the unit price inquiry information. unit price change determining means for determining a unit price change when the current time indicated by the clock circuit has reached the unit price change time corresponding to the product code of the unit price inquiry information in the change time storage unit; An electronic cash register equipped with a unit price reading device characterized by comprising a changed unit price reading device for reading a changed unit price corresponding to the product code from the product data storage device based on unit price change determination by the device. When unit price inquiry information is input, it is checked whether the current time has reached the unit price change time corresponding to the product code in the unit price inquiry information, and if so, it is determined that the unit price has been changed, and the change corresponding to the product code is made. Read unit price.

〔Example〕

Embodiments of the present invention will be described using the drawings. FIG. 1 is a hardware configuration diagram of a file controller which is a unit price reading device for an electronic cash register.

FIG. 2 is a system configuration diagram of the system. P.

In the S system, a plurality of electronic cash registers 13 and a file controller 14 that manages these electronic cash registers 13 are connected inline. Further, the electronic cash register 13 performs the registration work of sales products, and the file controller 14 reads out the registered unit price in response to an inquiry about the registered unit price from the electronic cash register 13 and sends it to the original electronic cash register 13. The registered data is stored for each item and for each cashier. When the file controller 14 receives inquiry information about the registered unit price from the electronic cash register 13, the file controller 14 searches the product code memory of its own single item table using the inquired product code data, and searches for the corresponding product. The registered unit price of the code is read and transmitted to the electronic cash register 13 of the transmission source. The electronic cash register 13 that has received the registered unit price displays and prints the registered unit price and performs the registration process.

FIG. 3 is a block diagram of the main memories used in this embodiment in RAM 4. The RAM 4 has a communication buffer for exchanging data with a plurality of electronic cash registers 13, as well as a single item table 15.

The single item table 15 includes a code memory 151 that stores product codes, a name memory 152 that stores product names, a change time memory 153 that is a change time storage section that stores unit price change times, and a change unit price memory that stores changed unit prices. A unit price change flag 155 indicating that the registered unit price has been changed, and a registered unit price memory 156 that stores the registered unit price to be referenced at the time of registration.

FIG. 4 is a flowchart showing the processing of this embodiment.

This flowchart is a flowchart of the file controller 14, and is executed when input of registered unit price inquiry information, which is a unit price read request, ie, product coat data is received from the electronic cash register 13. In step 100, the product code in the single item table 15 is searched based on the product code data received from the electronic cash register 13. If the same product coat as the product coat data does not exist in the single item table 15, the data is sent to the original electronic cash register 13 in step 106 without confirming that it is an error. If there is a product code that is the same as the product code data, it is checked in step 101 whether the unit price change flag 155 of that product code is set to 1. If the unit price change flag 155 is set to 1, the unit price has already been changed, so proceed to step 1.
In step 05, the registered unit price stored in the registered unit price memory 156 is read out, and in step 106, it is transmitted to the electronic cash register 13 from which the product code data was transmitted. When the electronic cash register 13 receives a registered unit price that is a response to the unit price read request, that is, the unit price inquiry information transmitted by itself, it executes a registration process using this registered unit price.

If unit price change flag 155 is not set to 1,
In step 102, which is a unit price change determination means, the unit price change time stored in the change time memory 153 of the corresponding product code is compared with the current time. If the current time is greater than the unit price change time, the unit price change time has not yet arrived, so the registered unit price stored in the registered unit price memory 156 is read out in step 105 without replacing the registered unit price, and the product code data is stored in step 106. is sent to the original electronic cash register 13. If the unit price change time is greater than or equal to the current time, it is the unit price change time, so step 103 sets the unit price change flag to 1, and step 104 sets the changed unit price stored in the changed unit price memory 154 and the registered unit price memory. The registered unit price stored in 156 is replaced. Then, in step 105, the registered unit price stored in the registered unit price memory 156 is read out, and in step 106, the changed registered unit price is transmitted to the electronic cash register 13 from which the merchandise controller sent it. Steps 103 to 105 are changed unit price reading means. When the electronic cash register 13 receives a registered unit price that is a response to the unit price read request, that is, the unit price inquiry information transmitted by itself, it executes a registration process using this registered unit price.

Next, the operation of this embodiment will be explained. For example, suppose the time is 17:00 and a customer buys radishes. and 17
Since then, the regular price of daikon radish has changed from 350 yen to 300 yen, and lettuce has a regular price of 2 yen.
Suppose that the sale price is reduced from 80 yen to 250 yen. The electronic cash register 13 is a file controller 14
In order to read the registered unit price of radish, 0001 of the product coat data of radish is sent to the file controller 14 as inquiry information. The file controller 14 receives an inquiry about the registration unit price from the electronic cash register 13.
searches for the received product code data 0001 among the product codes in the single item table and checks whether the unit price change flag is set. If the unit price change flag is not set, check the change time. Since the change time is 17:00, it matches the current time. As a result, the unit price change flag is set to 1, and 300 stored in the changed unit price memory is replaced with 350 stored in the registered unit price memory. 300 from the registered unit price memory is read out and transmitted to the electronic cash register I3 from which the product code data was transmitted.

At the electronic cash register 13, the price of radish was 300 yen.
Register as yen. In this way, the changed price can be reliably registered at the unit price change time.

Further, the registered unit price of lettuce is not changed even at 17:00, which is the unit price change time, but when an inquiry is made about the unit price of lettuce, the registered unit price is changed, read out, and registered.

Note that the present invention is not limited to this example.

For example, in this embodiment, a system in which a plurality of electronic cash registers are managed by a file controller has been described using the file controller as an example, but a single electronic cash register may be used. In addition, in this embodiment, only the discount start time is stored, and registration after that time is explained as an example where discount sales are carried out until the store closes. A configuration may be adopted in which the unit price returns to the original price after the elapse of time. In that case, add a return time to return to the original registered unit price in the single item table along with the change time, and check the current time, change time, and return time every time an inquiry about the registered car and price is made from the electronic cash register. Just do it. Furthermore, although the configuration is such that the registered unit price and the changed unit price are exchanged, it is also possible not to exchange them by changing the readout address. Various modifications can be made without departing from the gist of the invention.

〔Effect of the invention〕

a change time storage section provided in a part of the product data storage means to store a unit price change time corresponding to the product code; and a change time storage section provided in a part of the product data storage means to store a change unit price corresponding to the product code. Based on the input of a changed unit price storage unit, a clock circuit that measures the current time, and the unit price inquiry information, the current time indicated by the clock circuit corresponds to the product code of the unit price inquiry information in the changed time storage unit. unit price change determining means for determining that the unit price has been changed when the unit price change time has been reached; and a changed unit price for reading out the changed unit price corresponding to the product code from the product data storage means based on the unit price change determination by the unit price change determining means. Since it is equipped with a readout means, there is no problem such as a product whose unit price has not been changed yet and is sold at the unit price before the change. It can be done efficiently.
