Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product sales data processing device capable of processing registration data cancellation.

[Conventional technology] Conventionally, in this type of product sales data processing device, the business modes are ``registration'', ``inspection'', ``payment'', ``setting'', and ``setting''.
A mode selection switch is provided to switch to Cash Register Minus J, etc., and if you want to cancel the product sales data of a customer who has set the Registration J mode and entered it from a keyboard etc., set the mode selection switch to Register Minus J. ”
mode, the customer can cancel the registered data by re-registering the purchased products one by one using the same operations as when registering while looking at the receipt.

[Problems to be Solved by the Invention] However, when canceling registered data in this way, the "register minus" mode is set and the data that has been registered is re-registered one item at a time, which takes a long time. Especially when there are a large number of registered products, it takes a lot of time and is often not possible during normal registration work. There were various problems, such as the risk of losing receipts entrusted to customers by customers, and the risk of registration errors occurring since each item was re-registered.

The present invention has been made in view of the above points, and an object thereof is to provide a product sales data processing device that allows the cancellation of product sales data once registered with a simple operation, and is free from the possibility of cancellation errors. That is.

[Means for Solving the Problems] The present invention provides a product sales data processing device that registers product sales data input from an input unit, prints it out on a printer, and issues a receipt by operating a closing key. As shown in FIG. 1, there is a means for recording at least registered product sales data and its total data with a transaction number in a file memory a, and an erroneous registration number input means C for inputting an erroneously registered transaction number; Based on the transaction number input by this input means C, the file memory a
data reading means d for reading out corresponding product sales data and its total data; and erroneous registration receipt issuing means f for causing a printer e to print out the data read by the data reading means d to issue an erroneous registration receipt. ,
A data cancellation processing means Q for canceling the data read by the data reading means d is provided.

[Operation] In the present invention having such a configuration, when registering product sales data, at least the customer's product sales data and its total data are each assigned a transaction number and recorded in the file memory a. When a customer requests cancellation of the registered data due to cancellation of shopping, etc., by inputting the transaction number using the erroneous registration number input means C, the product sales data corresponding to the transaction number and its total are stored in the file memory a. Read data. The read product sales data and the total data are sequentially printed out on receipt paper by the printer e to issue an erroneously registered receipt. Further, data cancellation processing is performed based on the product sales data read out by the data cancellation processing means Q and the total data thereof.

[Example] This embodiment will be described below with reference to the drawings.

In this embodiment, the present invention will be described as applied to a POS system comprising a plurality of terminals and a terminal controller that controls each terminal.

5.

As shown in FIG. 4, the store controller SC includes a CPtJ31 that constitutes the main body of the control unit, a ROM32 that stores program data used by the CPU31 to control each unit, and various memories and flags for data processing. A RAM 33 is provided. Also, a transmission interface 34 for controlling data transmission with the file controller FC, a printer controller 36 for controlling the printer 35 and printing out data, etc.
A display controller 38 that controls the CRT display 37 to display data, etc., a keyboard controller 40 that controls the keyboard 39 and receives key signals from the keyboard 39, and is used when writing and reading data to and from the hard disk drive HD. An interface 41 is provided.

The CPU 31, ROM 32, RAM 33, transmission interface 34, controllers 36, 38, 40, and interface 41 are connected via a path line 42.

When the "registration" mode is set by the control switch 14, the CPLJll of each of the electronic cash registers ECR1 to ECRrL registers the products purchased by the customer, and the processing is as shown in FIG. That is, when product sales data is entered from the keyboard 21, the data is displayed on the CRT display 16, printed out on receipt paper by the printer 18, and registered in the RAM 13 in the department totalizer.

After this department registration processing is performed, when the closing key is operated on the keyboard 21, memory processing is performed to accumulate the customer's total data in the transaction-by-transaction totalizer of the RAM 13, and then the product of the customer just registered is processed. The sales data and the total data are assigned a register number and a transaction number and transmitted to the store controller SC via the file controller FC. Finally, the printer 18 is controlled to print out the total data and issue a receipt.

Further, when canceling registration, the CPU 11 performs the process shown in FIG. 6. That is, the register number and transaction number are input from the keyboard 21, and if there is a manual error in hitting a key incorrectly, the input register number and transaction number are transmitted to the store controller SC via the file controller FC. (Incorrect registration number input means) In this state, it waits to receive data from the store controller SC.

When data including the customer's product sales data and the total data corresponding to the register number and transaction number transmitted from the store controller SC is received, the printer 18 is controlled to display, for example, "Register Minus" on the receipt paper. and print it out to issue an incorrect registration receipt. (Misregistered receipt issuing means) Finally, data cancellation processing is performed on the departmental totalizer and transactional totalizer in the RAM 13. (Data Cancellation Processing Means) When the CPU 31 of the store controller SC receives registration data from the electronic cash registers ECR1 to ECRn, it performs the recording process shown in FIG. 7. This process records the product sales data and its total data together with the transaction number in the corresponding area of the hard disk drive HD in accordance with the register number attached to the received data. (Recording means)
In addition, the CPU 31 operates on electronic cash registers ECR1 to
When cancellation data is received from ECRrL, the recording process shown in FIG. 8 is performed. This process searches for a corresponding area in the hard disk drive HD based on the register number attached to the received data, and further searches for registered data recorded in the searched area based on the transaction number. Then, the searched registration data is read out, and the registration data is sent to the electronic cash register corresponding to the register number with a transaction number attached thereto. (Data reading means) In this embodiment having such a configuration, in each electronic cash register ECR1=ECRn, the keyboard 2
When product sales data is input from 1, that data is
displayed on the RT display 16 and the printer 1.
8 is printed out on the receipt paper. Also RAM
Registered in 13 departmental totalizers. This process is performed every time product sales data is input. When the input operation for the product purchased by the customer is completed, the user manually presses the closing key from the keyboard 21. As a result, the customer's total data is registered in the transaction-specific totalizer, and the customer's product sales data and the total data are sent to the store controller SC with the register number and transaction number attached.

Finally, the total data is printed out on a receipt paper to issue a receipt as shown in FIG. 9, for example. That is, the date, register number, b, product sales data, C, total data, d, transaction number, e, time f, etc. are printed on the receipt.

If the customer requests to cancel the purchase of the product after performing such registration, the customer receives a receipt from the customer, looks at the receipt, enters the register number a1 and the transaction number e from the keyboard 21, and operates the original note key. do. Then, the store controller SC receives the register number a and the transaction number e, searches the hard disk drive HD for the area corresponding to the register number, and further reads out the product sales data corresponding to the transaction number e and its total data from the area. , to the corresponding electronic cash register.

In this way, the corresponding electronic cash register prints out the received product sales data and its total data in the same format as at the time of registration, such as date a, register number b, product sales data C1 total data d, transaction number e1 and time f. 10th
An incorrect registration receipt as shown in the figure will be issued.

However, the character Q of "Register Minus" is also printed on this erroneously registered receipt to indicate that it is an erroneously registered receipt.

Further, data cancellation registration processing is performed on the departmental totalizer and transactional totalizer in the RAM 13.

In this way, to cancel all customer data that has been registered, all you have to do is enter the register number and transaction number from the keyboard 21 and operate the original key, instead of having to re-enter the cancellation data one by one as in the past. Since there is no such thing, cancellation operations can be easily performed in a very short time.

Therefore, even if the registration task is in progress, the cancellation operation can be executed after a short period of time. Moreover, there is no possibility that a cancellation error will occur.

In the above embodiment, the present invention has been described as being applied to a POS system equipped with a plurality of electronic cash registers, but the present invention is not necessarily limited to this, and can also be applied to a single electronic cash register. be. In this case, the file is provided in the register, and only the transaction number is required for number input at the time of cancellation.

[Effects of the Invention] As detailed above, according to the present invention, once registered product sales data can be canceled in a short time and with a simple operation.
Moreover, it is possible to provide a product sales data processing device that is free from the possibility of cancellation errors.
