Description

Error handling method of cash register

The present invention relates to an error handling method of a cash register, and more particularly, an alarm is issued through a display unit when an error occurs in a key input sequence, and at the same time, the user can easily process after an error occurs by issuing a type of inputable key through a receipt. The present invention relates to an error handling method of a cash register.

In general, a cash register refers to a device used to facilitate information management by processing various data accompanying product sales and informing a user of results. The range is from point of sales system to comprehensively manage distribution economy such as inventory and inventory research. Hereinafter, in the present specification, the term Electronic Cash Register (ECR), which means an electronic cash register controlled by a microprocessor, is used as a broad concept including a low-end cash register to a POS terminal.

Recently, as the function of the cash register becomes more complicated, an error occurs during key input due to a user's inexperienced use or an error in operation. When such an error occurs, the cash register divides the contents of the continuous buzzer sound and the error. The error code is shown on the display. In this case, the error code displayed is an error code of 'E1' on the display unit in case of an error caused by an input error of a function key, for example, depending on the occurrence of the error. Accordingly, the user checks the error code displayed through the display unit together with the buzzer sound, and accordingly performs a key operation (eg, a 'CLEAR' key) to solve the error occurrence.

However, if the user of the cash register is not familiar with the error contents according to the error code displayed when an error occurs and the types of keys that can be input after the error occurrence, the error contents should be interpreted by referring to the manual etc. when an error occurs. In addition, since a proper function key for resolving an error must be checked and operated manually, there is a problem in that the operation method becomes complicated and excessive error processing time is required when operating the cash register.

Accordingly, the present invention has been made to solve such a problem, the object of which is to warn the error situation occurred during the operation of the cash register and at the same time to display the function keys that can be input to solve the error occurred at the cash register error It is an object of the present invention to provide an error handling method of a cash register that can efficiently handle an occurrence.

In order to achieve the above object, an error processing method of a cash register according to the present invention is an error processing method of a cash register configured to display an error code according to an error occurrence when an error occurs due to a key input error. Determining whether an error has occurred, if it is determined that an error has occurred, determining an error occurrence and displaying an error occurrence, determining whether to input a clear key for erasing an error occurrence state, If it is input, clearing the generated error and determining whether an error key is input; if it is determined that the error key is input, the searchable key is searched after the error is generated, and the received inputtable key is received. Characterized in that it comprises a step of printing and printing on.

Hereinafter, with reference to the accompanying drawings, the configuration and operation and effect according to a preferred embodiment of the present invention will be described in detail.

First, Figure 1 is a system block diagram showing the configuration of a cash register to which the present invention is applicable. As shown in FIG. 1, the ECR system for implementing the present invention kisses the key input unit 20 and the key input unit 20 that generate various key codes for mode designation and money registration. The real time clock unit (RTC) 30, which designates an operation mode of the cash register and provides real time information to the central processing unit 10 and the central processing unit 10, which performs various functions in the designated mode. RAM 40 for storing various data generated during a program or transaction, ROM 50 for storing a system operation program, and printer for issuing documents for customer receipts and various processing results under the control of the central processing unit 10. And a display unit 70 for displaying various kinds of information related to the transaction under the control of the central processing unit 10.

On the other hand, Figure 2 is a key configuration diagram of the key input unit 20 to which the error processing method of the cash register according to the present invention can be applied, in practice, according to the height and ease of use of the model and the number (function) of keys It will be changed or added.

As shown in Fig. 2, the key configuration of the key input unit 20 to which the present invention can be applied is a mode switch 21 used to designate a desired operation mode among various operation modes of the ECR, and the amount or correspondence of various items. Numeric keys (27) used to input the numeric code, etc., item keys (25) used to specify the desired item, and function keys (23) used to execute a desired function among various functions provided in the ECR. The "error" key 23a and the "clear" key 23b which will be described later may belong to a function key group.

In this case, the 'error' key 23a is a key for receiving a signal for printing the type of a key that can be input after an error occurs on the receipt, and the 'clear' key 23b is for canceling the input number and error state. This key is used to cancel the status keys that are previously entered.

3 is a flowchart showing an error processing method of the cash register according to the present invention. As shown in the flowchart shown in FIG. 3, when a key is input in step S10, the scan key of the input key is interpreted in step S12 to determine the input key. At this time, in step S14, it is determined whether there is an error by determining whether there is a key input in an order which is not allowed by the system due to the user's immature use or mistake. In this case, when it is determined that an error has occurred, the error code according to the error occurrence factor is analyzed in step S16, and then in step S18, an error code indicating an error occurrence and contents of the generated error is displayed through the display unit. Done.

On the other hand, if an error due to a key input error does not occur as a result of the determination in step S14, the function corresponding to the key input in step S15 is performed.

At this time, in step S20, when the error occurs, it is determined whether the 'CLEAR' key 23b is input to solve the error occurrence state, and as a result of determination, the 'clear' key 23b is not input. If the step S18 is repeated and the 'clear' key 23b is inputted, the error state is cleared at step S22.

Further, in step S24, it is determined whether the user inputs an 'error' key 23a for printing on the receipt the type of the key that can be input after an error occurs. If the 'error' key 23a is not input as a result of the determination, the corresponding function of the key input in step S25 is performed. If the 'error' key 23a is input, after an error occurs in step S26 Search for an available key. Thereafter, in step S28, a receipt in which the type of the searchable input key is found is issued.

On the other hand, Figure 4 is an exemplary view of the receipt according to the error processing method of the cash register according to the present invention, as shown in Figure 4 will print a key that can be input according to the error content generated when the error occurs is issued a receipt.

As described above, the error handling method of the cash register according to the present invention displays the error occurrence contents when an error occurs, determines the inputable keys after the error occurrence, and prints the types of inputable keys on the receipt. To be issued.

Therefore, when an error occurs due to an incorrect key input due to a user's immature use or a mistake by an error handling method of a cash register according to the present invention, the user knows in advance the contents of the error and the types of keys that can be input for error cancellation. Even if it is not present, error canceling and subsequent key operation can be easily performed, so that an effective operation of the cash register can be obtained.
