Cash register with sales data retrieval and control method

The present invention relates to a cash register having a sales data recovery function and a control method. More particularly, the present invention relates to a cash register having a sales data recovery function that can be easily recovered within a short time by copying sales data stored in an accounting memory to an IC card. It relates to a register and a control method.

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 a result. It ranges from point of sales system to comprehensively manage the distribution economy such as research. Hereinafter, in this specification, the term electronic cash register controlled by a microprocessor is used as a broad concept including a low-end cash register to a POS terminal.

1 is a general system block diagram of a cash register as described above. As shown in this figure, the cash register is a printer for issuing documents for the customer's receipts, audit papers and various data processing results under the control of the central processing unit 10 and the central processing unit 10 that controls the overall operation of the cash register ( 20), a key input unit 30 for generating a mode designation signal and various key codes for money registration, a ROM 40 having a program for implementing various functions of the cash register, including a system operation program, and a money register RAM 50 for temporarily storing various data generated during the work, display unit 60 for displaying various data processing results generated during the money registration operation through an indicator such as a CRT under the control of the central processing unit 10, and power supply to the entire cash register. In case of power failure, power is supplied from a backup battery, which is generated during operation of the cash register, to preserve all data temporarily stored in the RAM 50. It is constructed by using a power source 70 and the bar code reader comprises a bar code reading unit 80 that recognizes data of the bar code attached to a commodity.

In order to process various kinds of data accompanying the money registration, that is, the sale of goods, using a cash register having the above-described configuration, various data are inputted through an input means such as a key input unit 30 or a barcode reading unit 80. The process must be preceded, and the data entered into the cash register is temporarily stored in the RAM 50 and then printed through the printer 20 and issued to a receipt or audit paper.

The audit paper as described above is printed on the same contents as the data printed on the receipt and wound in a roll form inside the cash register. The audit paper stores all the transaction details, that is, sales data, of the stores made for a certain period of time.

Meanwhile, the tax authorities impose taxes on the store owners based on the total sales for a predetermined period of time. In order to investigate the total sales of the stores, the tax office refers to an audit paper in which all sales data are recorded.

However, audit papers can be altered to some extent by users, and the contents of audit papers are frequently manipulated for tax portals. Therefore, in order to prevent the manipulation of the contents in recording and storing the sales data of the store, the cash register may further include a "Fiscal EPROM".

The accounting memory is a type of erasable programmable read only memory (EPROM). The accounting memory is a read memory that can be written but cannot be erased because data can be erased only by irradiation with ultraviolet rays. Therefore, by storing the sales data of the store in the accounting memory, the contents can be prevented from being manipulated.

In Eastern countries, the use of such accounting memory is mandatory, and in order to further secure security, the accounting memory is fixed to the bottom plate of the cash register case by welding or the like. Accordingly, when the tax department wants to check the sales every month or month, the accounting memory is collected.

However, in order for the tax department to recover the accounting memory, the cash register case bottom plate with the accounting memory must be removed, so that the recovered case bottom plate is replaced or replaced with a case bottom with another accounting memory before being reinstalled. There is a problem that data processing through the cash register is not performed.

The present invention has been made to solve the above-described problems, the data processing through the cash register is not interrupted for a long time in the process of recovering sales data by copying the sales data stored in the accounting memory to the IC card and easily recovered within a short time. It is an object of the present invention to provide a cash register and a control method having a sales data recovery function that can be performed smoothly, and can be easily transported and read out.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to a cash register and a control method having a sales data recovery function of the present invention according to a preferred embodiment.

First, FIG. 2 is an external perspective view of a cash register having a sales data recovery function of the present invention, and FIG. 3 is a system block diagram of a cash register having a sales data recovery function of the present invention. In the system block diagram of FIG. 3, the same reference numerals are given to the same parts as those shown in FIG. 1, and detailed description thereof will be omitted.

4 is a key configuration diagram of a cash register key input unit having a sales data recovery function, and FIG. 5 is a flowchart illustrating a sales data recovery method of the present invention.

As shown in FIG. 2, the cash register having the sales data recovery function is replaced by the power supply unit 70 of the general cash register with the new power supply unit 90. The accounting memory 100 and the accounting memory control unit ( 110) through the RS-232C control unit 120 and the RS-232C control unit 120, which is an interface for communication with other terminals, a communication protocol adopted and used by an IBM PC to operate data communication in an efficient manner. An IC card recording / reading unit 130 connected to the cash register is further provided.

The symbol "/" as mentioned above is used in the meaning of "or" in the description of the present invention and in the claims.

The power supply unit 90 of the cash register having the sales data recovery function of the present invention provides a voltage required for each functional unit of the cash register having the sales data recovery function, as well as a request for recording data in the accounting memory 100. Provides a specific voltage.

In detail, since the accounting memory 100 is a kind of EPROM, data can be written when a predetermined high voltage is applied. For example, if the power for driving the cash register is 5V and the power required for data recording in the EPROM is 12V during normal money registration, the sales data is easily recorded in the accounting memory 100 to which 12V is applied by the power supply 90. Can be. Then, when 5 V, which is a normal power supply, is applied to the cash register again, the accounting memory 100 functions as a general reading memory, that is, a ROM.

The accounting memory control unit 110 designates a storage address of various sales data to be recorded in the accounting memory 100 and induces a specific voltage to be applied to the accounting memory 100 during data recording.

On the other hand, IC (Integrated Circuit) card 132 is a card with a large LSI (Large Scale Integration) memory in a card of a few millimeters thick can store a large amount of data, in particular, there is an advantage that it is easy to carry .

In the configuration of the cash register having the sales data retrieval function of the present invention, the IC card recording / reading unit 130 connected to the cash register with a predetermined connector 134, such as a D-SUB 9 pin connector, is provided with an RS-232C control unit ( It is a means for recording predetermined data transmitted from the cash register under the control of 120 to the IC card 132 or reading data recorded in the IC card 132.

Keys of the key input unit provided in the cash register having the sales data recovery function are mode selection switches 32 used to designate a desired mode among various operation modes of the cash register, as shown in FIG. A function key group 34 used to select and execute a desired function among functions, an item key group 36 used to designate a sale item, and a numeric key used to input a price or a number requiring registration of various items It is divided into groups 38.

The function key group 34 may further be provided with a "sales data recovery key 34a" which is a key used to copy sales data of the accounting memory 100 to the IC card.

Hereinafter, the sales data recovery method of the cash register of the present invention, that is, the procedure of controlling the cash register having the sales data recovery function as described above will be described in detail with reference to the drawings and the flowchart of FIG. 5.

First, in step S10, it is determined whether the mode currently designated by the mode selection switch 32 of the key input unit 30 is a program mode.

If the result of the determination in step S10 is the program mode, the process proceeds to step S12 where a password is to be set through the "password setting function" which is one of the functions supported by the program recorded in the ROM 40. It is determined whether there is a doctor. Specifically, the cipher considered in step S12 is related to reading the accounting memory, which is used to determine whether the person who wants to read the accounting memory is the person who is allowed to read the accounting memory.

If there is no intention to set a password as a result of the determination in step S12, the process proceeds to step S14 where other functions supported in the program mode are performed or waited. However, if there is a desire to set a password as a result of the determination in step S12, the flow proceeds to step S16 to receive the password.

The password setting procedure from step S12 to step S16 will be described as an example. In the program mode, press " numeric key 7 " and then " enter key " to select " password setting function " . Then, after inputting a password of a predetermined string or numeric string, press the "enter key" to complete the password input.

After performing step S16, the process proceeds to step S18 to store the password input in step S16 in the storage area allocated to the RAM 50 in advance.

On the other hand, if the mode currently selected by the mode selection switch 32 of the key input unit 30 is not the program mode in step S10, the process proceeds to step S20 and the mode selection switch 32 It is determined whether the registration mode is selected.

If the registration mode is not specified as the result of the determination in step S20, a mode other than the program mode and the registration mode is selected among the various modes of the cash register, so the process proceeds to step S22 to perform the operation supported by the selected mode. Or wait.

However, when the registration mode is selected as a result of the determination in step S20, various data accompanying the sale of the product are input to the cash register through an input means such as a key input unit 30 or a barcode reading unit 80, and then processed and printed. As the money registration process such as printing through 20 is performed, it is determined in step S24 whether there is an input of the "sales data collection key 34a" provided in the key input unit 30.

As a result of the discrimination in step S24, when a key other than the "sale data collection key 34a" is input, the process proceeds to step S26 and the operation required by the input key is performed. However, if the result of the discrimination in step S24 is that the "sales data recovery key 34a" is input, the flow advances to step S28 to connect the cash register and the IC card recording / reading unit 130 by the connector 134. It is determined whether or not.

As a result of the discrimination in step S28, when the cash register and the IC card recording / reading unit 130 are disconnected due to physical or electrical factors, the process proceeds to step S30 and an error message is displayed on an indicator such as a CRT. Outputs an alarm. However, if the cash register and the IC card recording / reading unit 130 are connected as a result of the discrimination in step S28, the process proceeds to step S32 where a password is input from a person who wants to recover sales data of the accounting memory. .

After the execution of step S32, the process proceeds to step S34, and it is determined whether or not the password inputted in the step S32 and the preset password in the program mode match through the procedure from step S12 to step S18. Is determined.

If the determination results in step S34 do not coincide with each other, the flow advances to step S30 to output an error message. However, if the determination results in step S34 coincide with each other, the flow advances to step S36, where the sales data of the accounting memory is copied to the IC card. That is, the sales data transmitted by the RS-232C control unit 120 to the IC card recording / reading unit 130 is recorded in the IC card 132.

The sales data recovery method of the cash register of the present invention is not limited to the above-described embodiment, but may be modified in various ways within the scope of the technical idea of the present invention.

It is also to be understood that the term "step" as used in the detailed description of the present invention may not be semantically consistent with the term "step" to be used in the appended claims.

According to the cash register and the control method having the sales data recovery function of the present invention, the cash register in the process of recovering the sales data stored in the accounting memory by copying the sales data stored in the accounting memory to the IC card and easily recovering them in a short time. Through the data processing is smoothly performed without interruption for a long time, there is an effect that can easily transfer and read the recovered sales data.
