Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a sales data processing device such as an electronic cash register.

[Prior Art and its Problems] Conventionally, some electronic cash registers (ECRs) are configured so that data on both purchases and sales made with a credit card can be registered.

In this type of product, in addition to the various keys required for normal registration operations, there are also -1--1 selection of payment methods such as lump-sum payment or installment payment in order to execute the sales process in the cart. A large number of keys are required, such as keys for inputting payment details such as the payment start month, the payment amount for each month, or the bonus month and its payment m. Therefore, in this type of ECR, a key for normal registration processing and a key for cart processing are provided on the keyboard separately, or a key for specifying the start of card processing is provided, so that one key can handle normal registration processing. It is designed to have a double function function that can be used for both business and card processing.

However, if the key for normal processing and the key for card processing are provided separately, the number of keys will increase, and if the key is provided with a double function function, the cart processing key must be operated from the beginning. The operator must always be aware of the double-function machine, since the only thing to do is execute card processing, and as a result, key operations become sloppy, placing a burden on the operator. .

[Purpose of the Invention] This invention was made in view of the situation mentioned in -, and its [1] object is to easily execute card processing with a small number of keys without being aware of the double crank function. The aim is to provide a free data processing system.

[Summary of the Invention] In order to achieve the above-mentioned object, the present invention provides a sales data processing device equipped with a multi-function key that is selectively used for normal processing or card processing, as well as providing a cart reading means. This card reader is characterized in that when the recorded contents of the card are read by the card reading means, the +iii multi-function key is switched from a key for normal processing to a key for card processing.

[Example] Hereinafter, the present invention will be specifically explained based on an example of Mg shown in the drawings. Note that this embodiment shows an example in which the present invention is applied to an ECH, and this ECR is capable of transmitting and receiving data with a center-side ECR as a POS terminal.

Configuration of the Embodiment FIG. 1 is a block circuit diagram of an ECR as a POS terminal. 1 in the figure is the input section of this ECR, and the keyboard of this input section 1 has numeric keys, etc., as well as a double function that will be described later and is selectively used for normal processing or card processing. The old key I was holding was scratched.

In addition, "Settings" and "Settings" are displayed on the keyboard depending on the switching position.
A mode switch MS is provided for switching between "registration", "power supply 0FFJ", "inspection", and "payment" modes. The key input signals output from the input section 1 corresponding to the operation keys and the mode designation signals output corresponding to each switching position of the mode switch MS are input to the central processing circuit (CPU) 2, respectively. Ru. In addition, the input section 1 receives an input mode designation signal N from the CPU 2 to the machine 1 to designate whether the key is to be used for normal processing or for card processing.
/C is given. In addition to the keyboard, this ECR is also provided with a card reading device 3 as external input means, which reads data stored on a magnetic card or the like and provides it to the CPU 2. Note that the card read by this card reading device 3 is a credit card on which a user code and the like are magnetically recorded.

The CPU 2 controls various operations of this ECH, such as input processing and registration processing, and includes a control section, a calculation section, and a transmission register that temporarily stores data transmitted to and from the center side ECR (central control unit) that collects data. A flag register F1 is provided for storing a mode flag for switching between the normal processing input mode and the cart processing input mode. The CPU 2 then sends and receives data to and from the RAM (Random Access Memory) 3 to accumulate data for each section, and gives a read command to the ROM (Read Only Memory) 4 to read data from the ROM 4 in the system system.
, and controls the opening operation of the drawer 5. Further, the CPU 2 sends sales data, etc. to the printing section 6 to print it on receipt paper and journal paper, and display it on the display section 7 electro-optically. Further, data is exchanged between the CPU 2 and the transmission control unit 8, and data is exchanged with the central control unit (center side ECR) 9.

The RAM 3 executes data writing and reading operations under the control of the CPU 2, and is provided with a total memory for storing departmental sales total data and the like, as well as function conversion tables M1 and M2 for the multi-function keys. In this case, the conversion table Ml is normal! l! j, ri m, variation table m
2 is for cart processing, and the key code corresponding to the multi-function key is out of memory.

Next, referring to FIGS. 2 and 3, the multi-function keys on the keyboard and the corresponding conversion table M1. The relationship with M2 will be explained. Below the keyboard of the input section 1 is a liquid crystal display device consisting of two liquid crystal panels.One liquid crystal panel displays the function name for normal processing, and the other liquid crystal panel displays the name for card processing. The function names are switched and displayed according to the input mode designation signal N/C from the CPU 2. Here, FIG. 2(a) shows a1 for normal processing.
1 is the clear key, K2 is the multiplication key, K3 is the numeric key, K4 is the departmental key, 5 is the deposit key, K6 is the withdrawal key, K7 is the lending key, K8 is the correction key corresponding to the @ name. ,
K9 functions as a subtotal key, and K10 functions as a cash/FA credit key. FIG. 2(b) shows the contents of a function conversion table M1 in which key codes are stored in correspondence with each key in order to make the above-mentioned keys function for normal processing. In addition, in FIG. 3(a), corresponding to the function names for card processing, keys Kl~, 3 are clear keys as in normal processing,
It functions as a multiplication key and a numeric key, but in normal processing, the key 4 functions as a department key, and the key 4 functions as a reset and set key, or as a payment method selection key such as lump sum payment or bonus payment. Furthermore, in normal processing, the key KIO, which is used as a cash/deposit key, functions as a card reading end key. FIG. 3(b) shows the contents of a function conversion table M2 in which key codes are stored corresponding to each key in order to make the above-mentioned keys function for card processing.

Figure 4 is a flowchart that starts execution when the mode switch MS is set to the registration mode. First, in step S1, it is checked whether the cash card has been inserted into the card reading device 3 and the contents recorded on the card have been read. However, if the cash card is not currently inserted into the card reading device 2! , the process advances to step S6, and the one-function 'a' conversion table M1 is designated.

As a result, the contents of this conversion table Ml are read out and the function name is displayed in correspondence with the key on the liquid crystal display device of the input section 1. Therefore, in this case, the keys of the input unit 1 function as keys for normal processing as shown in FIG. 2(a). When the user visually confirms the displayed content and performs a departmental registration operation according to the normal key operation procedure, the presence or absence of key input is detected in step S7. If there is a key input now, it is checked whether the operation key is a registered key (department key) (step S8), and if it is a registered key, total sales data by department is generated according to the contents of the machine run conversion table M1. A registration process is performed to accumulate the total number of data (step 39). Further, when the transaction registration is completed and it is detected that a closing key (cash/deposit key, etc.) has been operated, a closing process (step S l O) corresponding to the operated key is executed.

When such registration processing and closing processing are completed, or when no key input is detected in step S1, the process proceeds to the next step SIR, where it is checked whether or not the card has been read. If the card has not been read, the process proceeds to step S1. In the case of "Return now, purchase with credit card", the customer inserts the card taken from the customer into the card reading device 3, and the card reading device 3 reads the user code etc. recorded on the credit card. Read and send to CPU2. by this,
The CPU 2 detects that the card is being read and proceeds to step S1.
Proceed to step 2. Here, the end of one registration for one product,
That is, it is checked whether registration is in progress, and if it is in the middle of registration and the registration of one departmental sales data that has just been keyed in has not been completed, step S1 executes J-, and step S9 described above is executed. , waits for the completion of 1 registration. If 1 registration is completed, a flag indicating the card processing input mode is set in the Fl register in step 313, and then the process returns to step S1.

When the card processing input mode is set in this way, this is detected in step S1, and the process proceeds to step S2, where the function conversion table M2 is designated. by this,
The contents of the function conversion table M2 are read out, and the function names are switched and displayed on the liquid crystal display device of the input section 1 in correspondence with the keys. Therefore, in this case, the key of input section 1 is the third key.
+,< As shown in (a), it functions as a key for card processing. When the user visually confirms the displayed contents and operates a desired key, the key code corresponding to the operated key is read out from the conversion table M2, and the CPU 2 thereby performs card processing based on the input data (step 33). Then, in the next step S4, it is checked whether the card end Y processing has been performed, that is, whether the car F, l take end key KIO has been operated, but if this key KIO is not operated, the process returns to step S1 and the operation keys are changed in the same way as described above. The corresponding card processing continues until the card reading end key KIO is operated. When the card reading line r key KIO is operated, a termination process is executed accordingly, and after the contents of the Fl register are cleared in the first step S5, the process returns to step S1. Therefore, the display contents of the input section 1 return to the display state of normal processing.

In this way, in this embodiment, if the contents of the card are read once,
Since the function conversion table M2 for cart processing is designated and the input unit 1 is switched to the a-name table, in this state, the multi-function key is automatically switched as a key for card processing. Therefore, the operator does not have to use double-function functions to perform cart processing.

[Effects of IJI Issue 1] As explained in detail, card reading In addition to providing a step, when the recorded contents of the card are read by this method reading means, the multi-function key is switched from the normal processing key to the cart processing key, so be aware of the double function function. This has the advantage of allowing card processing to be easily executed with fewer keys.
