The present invention relates to an electronic cash register, and more particularly to an item registration of the electronic cash register.

In general, an electronic cash register is used for the purpose of depositing and withdrawing cash or storing cash in a business that handles miscellaneous goods and a plurality of items. The electronic cash register registers the unit price and tax rate of each item in order to improve the efficiency of the user's selling behavior. Accordingly, the user can use the electronic cash register by extending the desired number of items with a minimum of key operations without going through a number of cumbersome key operations.

1 is a block diagram of the electronic cash register. The electronic cash register shown in FIG. 1 is a CPU 10 which processes various data of sales activities by a predetermined program and performs operation of the system, and a ROM connected to the CPU 10 to store various control programs and initial data. (ROM) 12, a RAM for temporarily storing information such as a unit price for each item for sales activities, a sale amount generated from sales activities, and the like, and a month and a month connected to the CPU 10. A timer 16 for providing time data, a display unit 18 for displaying sales information such as various amounts of money information or errors occurring during sales activities under the control of the CPU 10, and the CPU 10 A printer 20 for issuing a receipt for sales details under the control of a plurality of keys, and a plurality of keys for inputting various commands and key data for performing the operation of the CPU 10 (e.g., item keys, expansion keys, Key with output key) It consists of a code (22).

FIG. 2 shows the keyboard 22 in detail. The mode keys of the keyboard 22 of FIG. 2 are keys for selectively providing a stop mode, a registration mode, a check mode, a settlement mode and a program mode.

In particular, the registration mode is used when registering an item. The program keys PGM1, PGM2, PGM3, and PGM4 of the keyboard 22 are keys for the user to input the item upon registration. The PGM1, PGM2, PGM3, and PGM4 may be further provided on the keyboard 22 of the electronic cash register, or a key already provided may be set to have a specific function only in the registration mode.

3 is a flowchart of a conventional item registration method. Referring now to Figures 1 and 2 and 3 will be described in detail the operation of the electronic cash register according to the conventional item registration method.

The user can set a specific mode among a plurality of modes of the electronic cash register by using a mode key of the keyboard 22 of the electronic cash register. When power is applied to the electronic cash register, the CPU 10 of the electronic cash register receives the key data according to the key input of the mode key of the keyboard 22 set by the user and sets the mode of the electronic cash register.

When the key input to the mode key is a key input according to the registration mode, the CPU 10 sets the mode of the electronic cash register to the registration mode. When the electronic cash register is set in the registration mode, the user inputs the PLU number or item number by using the keyboard 22 to register the item.

At this time, if the item number is input, the CPU 10 performs step (24). In step (24), the CPU 10 receives key data generated by the user keying in the PLU number or the item number by using the keyboard 22 to register the item. The user presses the PGM1 key when the entry of the PLU number or item number for registering an item is completed. The PGM1 key indicates that the input of the item number or PLU number to be newly registered by the user has been completed. When the input of the PLU number or the item number is finished, the CPU 10 performs step 26. In step (26), the CPU 10 searches whether key data according to the input of the PGM1 key is transmitted. At this time, if the key data according to the key input of the PGM1 key is transmitted, the CPU 10 performs step 32, and if the key data according to the key input of the PGM1 key is not transmitted, step 28 is performed. In step (28), the CPU 10 reads error message data for displaying an error message from the RAM 14, and transmits the error message data to the display unit 18. The display unit 18 receives the error message data and displays an error. The reason for displaying the error message is to notify the user that the key data for the PGM1 key has not been transmitted even though the entry of the item number or the PLU number is completed, so as to start the flow again.

When the display of the error message ends, the CPU 10 performs step 30. In step (30), the CPU 10 performs step (24) when key data according to key input of the PGM3 key is transmitted. However, if the key data according to the key input of the PGM3 key is not transmitted, the CPU 10 performs step 28 above.

At this time, the PGM3 key is a key set to perform the item registration from the beginning again. Accordingly, the user can perform the registration again from the beginning when the electronic cash register is misused using the PGM3 key.

On the other hand, after the user ends the input for the PLU or item number and key-in the PGM1 key, the keyboard 22 inputs the code according to the PLU number and the item number. In the step (32), the CPU 10 receives the key data according to the key input of the code according to the PLU number and item number from the keyboard 22. When the user inputs the code according to the PLU number and the item number, the user key-presses the PGM2 key to notify the CPU 10 of the end of the code input. When the key input of the code is terminated, the CPU 10 performs step 34. If the CPU 10 does not receive the key data according to the key input of the PGM2 in step (34), the CPU 10 performs the step 32 again, and if the key data according to the key input of the PGM2 is received, the step (36) is performed. do. In step 36, the CPU 10 reads data corresponding to the code from the RAM 14; When the reading of the data is completed, the CPU 10 performs registration. The registration means that the read data is transmitted to the display unit 18 for display, and the data is stored in the registration buffer of the RAM 14. When the registration ends, the conventional registration flow ends.

In order to register a new item in the prior art as described above, there is an inconvenience of having to register by entering a new code even if there is something similar to a new item to be already registered.

Accordingly, an object of the present invention is to provide an item registration method using an existing code that can be registered again by modifying a code of an existing registered item.

In order to achieve the above object, the present invention reads a code of an already registered item, modifies the code, and then reads and registers data about the modified code from a memory.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the annexed drawings, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

4 is a flowchart illustrating an item registration method using an existing code according to a preferred embodiment of the present invention. Now with reference to FIGS. 1 and 2 and 4 will be described in detail the operation of the electronic cash register according to the item registration method using the existing code according to a preferred embodiment of the present invention.

The user can set a specific mode among a plurality of modes of the electronic cash register by using a mode key of the keyboard 22 of the electronic cash register. When power is applied to the electronic cash register, the CPU 10 of the electronic cash register receives the key data according to the key input of the mode key of the keyboard 22 set by the user, and sets the mode of the electronic cash register.

At this time, when the key input to the mode key is a key input according to the registration mode, the CPU 10 sets the mode of the electronic cash register to the registration mode. When the electronic cash register is set to the registration mode as described above, the user inputs the PLU number or the item number by using the keyboard 22 to register the item. When the item number is input, the CPU 10 performs step 38. In step (38), the CPU 10 receives key data generated as a user inputs a PLU number or an item number by using the keyboard 22 to register an item. The user presses the PGM1 key when the entry of the PLU number or item number for registering an item is completed. The PGM1 key is a key for indicating that the input of the item number or PLU number to be newly registered by the user is completed.

When the input of the PLU number or the item number is finished, in step 40, the CPU 10 searches whether key data according to the key input of the PGM1 key is transmitted. In this case, if key data according to key input of the PGM1 key is transmitted, step (46) is performed. If key data according to key input of the PGM1 key is not transmitted, step (42) is performed. In step 42, the CPU 10 reads error message data for displaying an error message from the RAM 14. Thus, the error message data is transmitted to the display unit 18. At this time, the display unit 18 receives the error message data and displays an error.

At this time, the reason for displaying the error message is to notify the user that the key data for the PGM1 key has not been transmitted even though the entry of the item number or the PLU number is completed, so as to start the flow again.

On the other hand, when the display of the error message is finished, the CPU 10 performs step (44). In step 44, if the CPU 10 transmits key data according to a key input of the PGM3 key, the CPU 10 performs step 38 again. However, if the key data according to the key input of the PGM3 key is not transmitted, the CPU 10 performs step (42) again.

At this time, the PGM3 key is a key set to perform the item registration from the beginning again. Accordingly, the user can perform the registration again from the beginning when the electronic cash register is misused using the PGM3 key.

On the other hand, in step (46), the CPU 10 searches whether the key data is transmitted from the keyboard 22 according to the key input of the PGM4 key, and if the key data is transmitted, performs the step (52), and the key of the PGM4 key. If the key data according to the input is not transmitted, step (48) is performed. The PGM4 key is a key for setting an item modification in which a user modifies and registers an already registered item. If the user does not set the item modification using the PGM4 key, the key data for the PGM4 key is not transmitted to the CPU 10, and the CPU 10 performs step (48). The user inputs the code according to the PLU number and the item number by using the keyboard 22 to perform item registration. In step 48, the CPU 10 receives the key data according to the key input of the code according to the PLU number and the item number from the keyboard 22. When the user inputs the code according to the PLU number and the item number, the user key-presses the PGM2 key to notify the CPU 10 of the end of the code input. When the key input of the code for the PLU number and the item number ends, the CPU 10 performs step 50. If the CPU 10 does not receive the key data according to the key input of the PGM2 in step (50), the CPU 10 performs step (48) again, and if the key data according to the key input of the PGM2 is received, the step (60) is performed. do. In the step (60), the CPU 10 reads data corresponding to the code transmitted in the step (50) from the RAM (14). When the reading is finished, registration is performed. The registration refers to transferring the data to the display unit 18 for display and storing the data in the registration buffer of the RAM 14. Upon completion of the registration, the flow ends in the preferred embodiment of the present invention.

If the user sets the item modification in the step (46), and the key data according to the key input for the PGM4 key is transmitted to the CPU 10, step (52) is performed. The user inputs the PLU number and the item number for the pseudo code using the keyboard 22. In step 52, the CPU 10 receives key data according to the key input. When the reception of the key data for the similar PLU number and the item number ends, the CPU 10 performs step 54. In step 54, the CPU 10 reads the code for the similar PLU number and the item number from the RAM 14, and transmits the read data to the display unit 18. The display unit 18 receives the data and displays it. When the display of the data is finished, the CPU 10 performs step 56. The user makes a correction where it should be corrected in the contents of the code displayed on the display 18.

In a typical electronic cash register, a cursor is displayed on the display unit 18. At this time, the user moves the cursor to the desired place to perform the modification. CPU 10 receives the modified data. When the reception ends, the CPU 10 stores the modified data in the RAM 14. When the storing is completed, the CPU 10 performs step 58. At this time, the user inputs the PGM2 key when data modification is finished. The key input key data is transmitted to the CPU 10.

On the other hand, in step 58, the CPU 10 performs step 60 when the key data according to the key input of the PGM2 is transmitted from the keyboard 22, and if the key data according to the key input of the PGM2 is not transmitted ( Perform step 56 again. In step 60, the CPU 10 reads data corresponding to the modified code from the RAM 14. When the reading is finished, registration is performed. The registration refers to transferring the data to the display unit 18 for display and storing the data in the registration buffer of the RAM 14. When the registration ends, the flow according to the preferred embodiment of the present invention ends.

As described above, the present invention can be registered by modifying a similar code at the time of item registration, so that a similar code is not newly registered, but simply modified and registered to enable registration without a user providing key input using multiple keys. In addition, there is an advantage that can prevent the wrong input that can occur by keying a number of keys.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the invention should not be defined by the described embodiments, but should be defined by the equivalents of the claims and the claims.
