Description

The present invention relates to data processing apparatus and program.

  Conventionally, in a retail store such as a department store or a supermarket, a salesperson performs a series of operations such as calculating the price of a product while meeting a customer and recording the calculation result as the sales of the store. In recent years, sales data processing apparatuses such as ECR (Electronic Cash Resistor) and POS (Point of Sales) terminals have become widespread in order to digitize such work. That is, the salesperson serves as an operator while operating the sales data processing apparatus.

  The sales data processing apparatus is provided with a drawer called a drawer for storing sales. The drawer is normally closed and can be opened under the control of the sales data processing apparatus only when a predetermined operation is performed by the operator. Note that the drawer once opened is closed by manual operation of the operator.

The drawer is generally opened and closed with a predetermined operation by an operator. Specifically, the drawer is opened and closed in accordance with the operation of storing the price received from the customer in the drawer and the operation of drawing out the change to be delivered to the customer from the drawer. Therefore, since the opening and closing of the drawer accompanying such a predetermined operation is a short time, if the drawer has been opened for a long time, there is a suspicion that cash has been illegally withdrawn from the drawer.
Therefore, Patent Documents 1 and 2 disclose a technique for issuing a warning when the drawer opening time exceeds a reference value.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing an external configuration of a sales data processing apparatus according to an embodiment of the present invention.

  As shown in FIG. 1, the sales data processing apparatus 10 includes a numeric key 21, a function key 22, a display unit 23, a printing unit 24, and a drawer 25.

  Although not shown, the numeric key 21 is composed of a plurality of keys on which various numbers are printed. Each of the plurality of keys is assigned a function of inputting a printed number to the main body of the sales data processing apparatus 10. That is, the operator can input the desired number to the sales data processing device 10 by pressing the key on which the desired number is printed out of the number keys 21.

Although not shown, the function key 22 is composed of a plurality of keys on which various function names are printed. Each of the plurality of keys is assigned a function for notifying the main body of the sales data processing apparatus 10 of the printed name function.
Here, the function means an operation performed by the operator operating the sales data processing apparatus 10. Executable functions are determined for each operator, and the operator depresses the function key 22 on which the name of the function name currently performed or most recently performed is printed. The sales data processing apparatus 10 recognizes the function printed on the pressed key as a function that the operator performs or has performed most recently.
Details of the function will be described later with reference to FIG.

The display unit 23 is composed of a liquid crystal display or the like, and displays various information necessary for the operator's work as an image.
The printing unit 24 prints various information necessary for the operator's work, a receipt handed over to the customer, and the like on a paper medium for output.
The drawer 25 is a drawer for storing sales money, and is normally closed, but is opened by the control of the sales data processing device 10 when a predetermined operation is performed by the operator. Note that the drawer 25 once opened is closed by a manual operation of the operator.

  Here, an outline of the operation of the sales data processing apparatus 10 by the operator (hereinafter referred to as “sales data processing operation” as appropriate) will be described.

First, in order to start an operation for processing sales data, the operator performs a login operation by pressing the numeric key 21 or the like and inputting an operator number.
The sales data processing apparatus 10 checks whether or not the input operator number is registered. If the registered operator number is registered, the sales data processing apparatus 10 executes a login process, and if not registered, prohibits the login process. The sales data processing apparatus 10 stores the logged-in operator number in an internal memory (such as a storage unit 40 in FIG. 3 described later).

  When the login process is executed, the operator can use one or more preset functions. That is, the operator can perform various key operations on the sales data processing apparatus 10 in accordance with these functions.

FIG. 2 is a diagram illustrating an example of a function in a table format.
In the table of FIG. 2, the predetermined row corresponds to a predetermined one function. That is, in a predetermined row, an item in the first column describes a code (hereinafter referred to as “function code”) that uniquely indicates the function associated with the row. In the item in the second column of the row, the name of the function associated with the row (hereinafter referred to as “function name”) is described. In the item of the third column of the row, the specific content of the function associated with the row (hereinafter referred to as “function content”) is described.
For example, it can be seen that the function in the first line has a function code of “0001” and a function name of “preparation for change”. Further, the function content regarding the “change preparation” is “used when changing the sales data processing apparatus 10 before opening the store. The total amount of the prepared change is input with the number keys 21 and the change of the function key 22 is used. When the preparation key is pressed, the drawer 25 is automatically opened, so that the change is put in the drawer 25 and then the drawer 25 is closed by hand.
The change preparation key is a key on which the function name “change preparation” is printed out of the function keys 22. Hereinafter, the other function keys 22 will be expressed with the printed function name at the head.

  Here, as a specific example of various key operations involving functions, when a customer purchases a first product with a price of 500 yen and a second product with a price of 250 yen, the payment amount of the customer is the sales amount of the store. A series of key operations that are performed before being registered as will be described.

  In this case, the operator depresses the number key 21 and the like, and inputs a number of 500 as the price for the first product. Similarly, the operator depresses the number key 21 and the like, and inputs 250 numbers as the price of the second product. Then, the sales data processing apparatus 10 stores the price of the first product 500 yen and the price of the second product 250 yen in the internal memory.

  Although not shown, the sales data processing apparatus 10 may be configured to assign each product to each key and acquire the price of each product from the inside or the outside. For the sales data processing apparatus 10 having such a configuration, the operator depresses the key to which the first product is assigned instead of the numeric key 21. Similarly, the operator depresses the key to which the second product is assigned. Then, the sales data processing apparatus 10 acquires the price of 500 yen for the first product and the price of 250 yen for the second product, and stores them in the internal memory.

At this stage, the operator shall discount 50 yen from the total amount of the first product and the second product. In this case, the function in the second row in FIG. 2, that is, the “discount” function is executed by the operator.
Specifically, according to the function contents of “discount” on the second line, the operator presses the numeric key 21 or the like while inputting the product to be sold (while inputting the price of each product). Enter a number of 50 as the discount amount. Then, the sales data processing apparatus 10 stores the discount price (-50 yen in this example) in the internal memory together with the price of the product (500 yen for the first product and 250 yen for the second product in this example). To do.
Then, the operator depresses the discount key of the function key 22. As a result, the sales data processing apparatus 10 recognizes that the “discount” function has been executed, subtracts the discount amount from the total amount input so far, and causes the display unit 23 to display the subtraction result. Specifically, in this example, the sales data processing apparatus 10 calculates 500 yen (the price of the first product) +250 yen (the price of the second product) −50 yen (the discount amount), and the calculation result, that is, 700 An image showing a circle (a numerical image of 700) is displayed on the display unit 23.

A customer who wants to purchase the first product and the second product can view the payment amount from the display on the display unit 23 of the sales data processing apparatus 10. For example, it is assumed that the above-mentioned 700 yen is displayed on the display unit 23 as the payment amount, and the customer delivers 1000 yen to the operator in cash. That is, it is assumed that the operator has received 1000 yen as a deposit from the customer.
In this case, the function of the third line in FIG. 2, that is, the “cash” function is executed by the operator.
Specifically, according to the function content for “cash” on the third line, the operator depresses the number key 21 and the like to input a number of 1000 as a deposit amount from the customer. Press the cash key.
Then, the sales data processing apparatus 10 recognizes that the “cash” function has been executed, subtracts the payment amount from the deposit amount, and causes the display unit 23 to display the subtraction result as a change amount. Specifically, in this example, the sales data processing apparatus 10 calculates 700 yen (payment amount = the price of the first product + the price of the second product−the discount amount) from 1000 yen (the deposit amount). As a result, that is, an image indicating that the amount of change is 300 yen (a numerical image of 300) is displayed on the display unit 23.
Then, the sales data processing apparatus 10 automatically opens the drawer 25. The operator pays a deposit of 1000 yen to the drawer 25, takes out a change of 300 yen from the drawer 25, and gives it to the customer. When the operator hands the change to the customer, the operator completes the “cash” function and closes the drawer 25 by hand.

  During this time, the sales data processing apparatus 10 registers (stores) 700 yen as the sales proceeds of the store in the internal memory. Further, the sales data processing apparatus 10 stores the above-described sales data processing operation history (hereinafter referred to as “operation history”). The storage location of the operation history is not particularly limited, and may be an external device (such as a server (not shown)) of the sales data processing device 10, but in this embodiment, an internal memory (a storage unit 40 in FIG. 3 described later). Etc.) is adopted.

  Here, functions can be broadly classified into functions that do not involve the opening of the drawer 25 such as “discount” described above, and functions that involve the opening of the drawer 25 such as “cash” described above. Therefore, in the present embodiment, in order to clearly distinguish these two types of functions, “0” is set for a function that does not involve the opening of the drawer 25, and for a function that involves the opening of the drawer 25. A flag in which “1” is set is employed. Hereinafter, such a flag is referred to as a “drawer automatic open flag”.

  A function whose drawer automatic open flag is “1” is executed by a combination of routine operations for the operator. For example, when the opening / closing of the drawer 25 is observed, a routine operation of pressing the function key 22 is performed to open the drawer 25, and thereafter, a routine operation of manually tightening the opened drawer 25 is performed. It can be said that such a fixed operation or a combination of a plurality of fixed operations in the predetermined function is a standard operation of the predetermined function. Therefore, hereinafter, one routine operation or a combination of a plurality of routine operations in a predetermined function is referred to as “standard operation of the predetermined function”.

As long as the standard operation of a predetermined function is normally performed, the opening / closing time of the drawer 25 associated with the predetermined function should be shorter than a certain time even if there is a certain individual difference between operators. In other words, in spite of the standard operation of the predetermined function, if the opening / closing time of the drawer 25 is longer than a certain time, an operation that is suspected of illegally withdrawing cash from the drawer 25, that is, an abnormal drawer operation is performed. It will be broken.
Further, as long as the standard operation of the predetermined function is normally performed, the opening / closing frequency of the drawer 25 associated with the predetermined function should be less than the predetermined number even if there is a certain individual difference of the operator. . In other words, in spite of the standard operation of a predetermined function, if the number of times the drawer 25 is opened and closed is equal to or greater than a certain number of times, an operation that is suspected of illegally withdrawing cash from the drawer 25, that is, an abnormal drawer operation is performed. It will be broken.

In this way, in order to determine whether or not an abnormal drawer operation has been performed, such as a certain time for the opening / closing time of the drawer 25 or a certain number of times for the opening / closing of the drawer 25 with respect to a standard operation of a predetermined function. It is possible to set a standard for the above.
The predetermined function can be executed when the predetermined function key is pressed. Accordingly, it can be understood that the operation of pressing a predetermined function key with the drawer automatic open flag set to “1” is an operation of opening the drawer 25.
When grasped in this way, it is possible to set in advance a standard operation standard of a predetermined function executed by the operation for each operation of opening the drawer 25.

In this case, the sales data processing apparatus 10 can execute the following series of processes.
That is, the sales data processing apparatus 10 acquires a history of each operation by the operator.
Further, the sales data processing apparatus 10 acquires a standard operation standard for an operation specified from the history among standard operation standards set in advance for each operation of opening the drawer 25.
The sales data processing apparatus 10 obtains a difference from the standard of the acquired standard operation for each operation specified from the history, and detects an abnormal drawer operation when there is a difference greater than or equal to a predetermined value.
Such a series of processes is hereinafter referred to as “drawer abnormality detection process”.

Here, when there is a possibility that a plurality of operators may operate the sales data processing apparatus 10, the standard operation standard may be set uniformly for all operators. As a result, erroneous detection occurs, or conversely, accurate detection becomes difficult.
Therefore, in this embodiment, the standard operation standard is individually set for each operator. Thereby, erroneous detection can be reduced and detection with high accuracy can be realized.

  FIG. 3 is a block diagram illustrating a hardware configuration of the sales data processing apparatus 10 capable of executing the drawer abnormality detection process.

The “drawer automatic open flag” is set to “1” when the function associated with the row is associated with the opening of the drawer 25 and is set to “0” when the drawer 25 is not associated with the opening. Flag.

Returning to FIG. 4, the abnormality detection unit 123 obtains the standard operation standard (drawer opening permission of the drawer opening / closing management table in FIG. 8) for each combination of the operator and the function specified from the operation history file (see FIG. 7). Time and the number of drawer open permits) are obtained, and if there is a difference greater than a predetermined value, it is detected as an abnormal drawer operation.
Details of detection of an abnormal drawer operation by the abnormality detection unit 123 will be described later with reference to FIGS. 15 to 19.

The abnormality information output control unit 104 generates information for notifying an abnormal drawer operation detected by the abnormality detection unit 123 (hereinafter referred to as “abnormal information”), and controls the output unit 37 to output the information. .
For example, the abnormality information output control unit 104 controls the printing unit 24 of the output unit 37 to print abnormality information as shown in FIG. 11 on a paper medium. The abnormality information printed on the paper medium is hereinafter referred to as a “drawer open abnormality report”.

  FIG. 11 is a diagram illustrating an example of a drawer open abnormality report. Specifically, FIG. 11A is a diagram illustrating an example of a drawer open time abnormality report. FIG. 11B is a diagram showing an example of a drawer open frequency abnormality report.

  As shown in FIG. 11 (a), in the drawer open time abnormality report, various information when an abnormality in the opening time of the drawer 25 is detected as an indication of an abnormal drawer operation is printed. Specifically, the date and time when the abnormality was detected, the operator who caused the abnormality, the name of the function that was the target of the abnormality, the amount entered at the time of the abnormality, and the drawer 25 at the time of the abnormality The opening time (abnormal time) is printed.

  As shown in FIG. 11B, in the drawer open frequency abnormality report, various information when an abnormality in the opening / closing frequency of the drawer 25 is detected as an indication of an abnormal drawer operation is printed. Specifically, the date and time when the abnormality was detected, the operator who caused the abnormality, the name of the function subject to the abnormality, and the number of times the drawer 25 was opened and closed (the number of abnormalities) Printed.

  Next, various processes of the sales data processing apparatus 10 having the functional configuration of FIG. 4 will be described with reference to the flowcharts of FIGS.

FIG. 12 is a flowchart for explaining an example of a flow of processing for generating an operation history file (hereinafter referred to as “operation history file generation processing”) among the history generation processing executed by the sales data processing apparatus 10.
When the operation history file generation process is executed, each functional block in FIG. 4 functions in the CPU 31 and the following process is executed. In other words, the operation subject of the following steps corresponds to the CPU 31 in hardware. However, in order to facilitate understanding of the present invention, the processing of the following steps will be described on the assumption that each functional block functioning in the CPU 31 is an operation subject.

In step S1, the main control unit 101 determines whether or not a login operation by the operator has been performed.
When the login operation by the operator is not performed, it is determined as NO in Step S1, and the process returns to Step S1. That is, the determination process of step S1 is repeatedly executed until the login operation by the operator is performed.
Thereafter, when the operator performs a login operation, it is determined as YES in Step S1, and the process proceeds to Step S2.
In step S2, the main control unit 101 executes a login process.
For example, when the operator code input by the login operation is “0001”, the main control unit 101 recognizes that the operator is registered as “Arimori” (see FIG. 9), and Allow login.

In step S3, the operation history information generation unit 111 determines whether the function key 22 has been pressed.
If the function key 22 has not been pressed, it is determined as NO in Step S3, and the process proceeds to Step S6.
In step S <b> 6, the main control unit 101 determines whether or not the sales data processing apparatus 10 is powered off.
If the power is on, it is determined as NO in step S6, the process returns to step S3, and the subsequent processes are repeated. That is, when the power is on and the function key 22 is not pressed, the loop process of step S3 (NO) and step S6 (NO) is repeated, and the operation history file generation process is on standby. It becomes a state.
If the power is turned off during this time, it is determined as YES in step S6, and the operation history file generation process is ended.
On the other hand, if the function key 22 is pressed while the power is kept on during this time, it is determined as YES in Step S3, and the process proceeds to Step S4.

In step S4, the operation history information generation unit 111 acquires the operation history information and stores it in the operation history information file (see FIG. 5).
Specifically, the operation history information generation unit 111 includes the date and time when the operator depresses the function key 22, the function code and name of the function corresponding to the depressed key among the function keys 22, the drawer automatic open flag, The operator's name and the input amount are acquired as operation history information and stored in the operation history information file.

In step S <b> 5, the main control unit 101 executes function processing corresponding to the pressing operation of the function keys 22. The main control unit 101 opens the drawer 25 via the drawer control unit 38 when the function is of a type that involves opening the drawer 25, that is, when the drawer automatic open flag is “1”.
The drawer 25 once opened is closed by the manual operation of the operator.
Thereafter, the process returns to step S3, and the subsequent processes are repeated.
That is, every time the operator presses the function key 22, the loop processing of step S3 (YES), step S4, and S5 is repeatedly executed, and the operation history information acquired each time is stored in the operation history information file. It is appended (memorized).
Thereafter, when the power is turned off, the operation history file is terminated.

  During this time, the opening / closing history information generating unit 112 generates drawer opening / closing history information and stores it in the drawer opening / closing history file each time the opening / closing of the drawer 25 is detected by the sensor unit 39 (see FIG. 6).

Next, the drawer abnormality detection process will be described with reference to FIG.
FIG. 13 is a flowchart for explaining an example of the flow of a drawer abnormality detection process.
The drawer abnormality detection process is started, for example, when the sales data processing apparatus 10 is executing the settlement process after the business of the day is finished and the store manager logs in the sales data processing apparatus 10 as an operator.
When the drawer abnormality detection process is executed, each function block of FIG. 4 functions in the CPU 31 and the following process is executed. In other words, the operation subject of the following steps corresponds to the CPU 31 in hardware. However, in order to facilitate understanding of the present invention, the processing of the following steps will be described on the assumption that each functional block functioning in the CPU 31 is an operation subject.

  In step S <b> 21, the reference information acquisition unit 122 reads the drawer opening / closing management table (see FIG. 8) from the reference information storage unit 131.

  In step S <b> 22, the history information acquisition unit 121 executes a process for creating an intermediate merge file (hereinafter referred to as “intermediate merge file creation process”). Details of the intermediate merge file creation processing will be described later with reference to FIG.

  In step S <b> 23, the abnormality detection unit 123 executes a process for detecting a drawer open abnormality time (hereinafter referred to as “drawer open abnormality time detection process”). Details of the drawer open abnormal time detection process will be described later with reference to FIGS. 15 to 17.

  In step S <b> 24, the abnormality detection unit 123 executes a process for detecting the number of drawer open abnormalities (hereinafter referred to as “drawer open abnormality number detection process”). Details of the drawer open abnormality frequency detection process will be described later with reference to FIGS. 18 and 19.

In step S25, the main control unit 101 deletes the operation history information and the drawer opening / closing history information.
Thereby, the drawer abnormality detection process ends.

Next, the intermediate merge file creation process will be described with reference to FIG.
FIG. 14 is a flowchart for explaining an example of a detailed flow of the intermediate merge file creation process of step S22 in the drawer abnormality detection process of FIG.

In step S <b> 41, the history information acquisition unit 121 reads only the function record (operation history information) that accompanies the opening of the drawer 25 from the operation history file stored in the operation history information storage unit 132.
Specifically, the history information acquisition unit 121 reads only the operation history information (record) whose drawer automatic open flag is “1” from the operation history information included in the operation history file.
Referring to the example of FIG. 5, operation history information (records) of the functions “change preparation”, “cash”, and “exchange” is read.

  In step S <b> 42, the history information acquisition unit 121 takes the read record (operation history information) into the intermediate merge file of the integrated history information storage unit 134.

  In step S43, the history information acquisition unit 121 reads all the records (drawer opening / closing history information) of the drawer opening / closing history file stored in the opening / closing history information storage unit 133. Referring to the example of FIG. 6, all the drawer opening / closing history information (records) for 8 lines are read.

  In step S <b> 44, the history information acquisition unit 121 takes the acquired record into the intermediate merge file of the integrated history information storage unit 134.

  In step S45, the history information acquisition unit 121 rearranges the records of the intermediate merge file (operation history information and drawer opening / closing history information with the opening of the drawer 25) in the integrated history information storage unit 134 in time series. Thereby, for example, the intermediate merge file shown in FIG.

In step S46, the integrated history information generation unit 135 stores the intermediate merge file (see FIG. 7A) rearranged in the process of step S45 in the integrated history information storage unit 134.
Thus, the intermediate merge file creation process ends. Thereafter, the process proceeds to a drawer open abnormality detection process in step S23 of FIG.

Accordingly, the drawer open abnormal time detection process will be described with reference to FIGS. 15 and 16.
15 and 16 are flowcharts for explaining an example of a detailed flow of the drawer open abnormality time detection process of step S23 in the drawer abnormality detection process of FIG.

In step S60, the abnormality detection unit 123 places a pointer on the first line of the intermediate merge file. It is assumed that the pointer indicates a line (record) to be read.
In step S61, the abnormality detection unit 123 initializes the abnormality time detection count i to zero. The abnormal time detection count i will be described later.

In step S62, the abnormality detection unit 123 determines whether a record exists at the position indicated by the pointer in the intermediate merge file.
If the record does not exist, NO is determined in step S62, and the process proceeds to step S76. However, the processing after step S76 will be described later.
On the other hand, if a record exists, it is determined as YES in step S62, and the process proceeds to step S63.
In step S63, the abnormality detection unit 123 reads the record indicated by the pointer from the intermediate merge file.
Specifically, for example, in the intermediate merge file in FIG. 7A, it is assumed that a point is arranged at the position of the fourth line from the top. In this case, the abnormality detection unit 123 reads the record on the fourth line, that is, the combination of “Ito” by the operator using the “cash” function.

In step S64 in FIG. 16, the abnormality detection unit 123 determines whether or not the read record is a function record.
When the read record is originally a record of the drawer opening / closing history file, it is a record indicating opening / closing of the drawer 25 (open or closed record), so it is determined as NO in step S64, and the processing is performed. Proceed to step S75. However, the processing after step S75 will be described later.
On the other hand, if the read record is originally a record of the operation history file, it is a function record, so that it is determined as YES in Step S64, and the process proceeds to Step S65. In the above example, that is, in the example in which the record in the fourth line of the intermediate merge file in FIG. 7A is read, since it is a record of the function of “cash”, it is determined as YES in step S64, Advances to step S65.

In step S65, the abnormality detection unit 123 searches the drawer opening / closing management table for the drawer open permission time for the operator and function corresponding to the record read in the process of step S63.
Such a series of processes in step S65 is hereinafter referred to as “permitted time search process”. Details of the permission time search process will be described later with reference to FIG.
For example, in the above example, that is, the record in the fourth line of the intermediate merge file in FIG. 7A is read, the drawer opening / closing management of FIG. 8 is performed because the “cash” function and the operator are “Ito”. From the first row of the table, it is searched that the drawer open permission time is 30 seconds.

In step S66, the abnormality detection unit 123 determines whether the drawer open permission time is the maximum value.
The drawer open permission time being the maximum value means that there is no restriction on the opening time of the drawer 25 for the combination of the operator and the function corresponding to the record read in the process of step S63. In such a case, it is determined as YES in Step S66, and the process proceeds to Step S75 in FIG. However, the processing after step S75 will be described later.
On the other hand, when the drawer open permission time is not the maximum value, it is determined as NO in Step S66, and the process proceeds to Step S67. For example, in the above example, that is, in the example in which the drawer opening permission time is searched for from the first row of the drawer opening / closing management table of FIG. 8 to be 30 seconds, it is determined as NO in step S66, and the processing is step. Proceed to S67.

  In step S67, the abnormality detection unit 123 advances the pointer in the intermediate merge file by one record. In the above example, that is, in the example in which the pointer is set on the fourth line of the intermediate merge file in FIG. 7A, the pointer moves to the fifth line.

In step S68, the abnormality detection unit 123 determines whether a record exists at the position indicated by the pointer in the intermediate merge file.
If the record does not exist, it is determined as NO in Step S68, and the process proceeds to Step S76 in FIG. However, the processing after step S76 will be described later.
On the other hand, if a record exists, it is determined as YES in step S68, and the process proceeds to step S69.
In step S69, the abnormality detection unit 123 determines whether the read record is a closed record.
If the read record is originally an open record of the drawer opening / closing history file (record indicating opening of the drawer 25) or an original operation history file record, it is determined as NO in step S69. The process proceeds to step S77. In the above example, that is, in the example in which the pointer moves to the fifth line of the intermediate merge file in FIG. 7A, the record on the fifth line is an open record, so it is determined as NO in step S69. The process proceeds to step S77.

In step S77, the abnormality detection unit 123 determines whether the read record is a function record.
If the read record is a function record, it is determined as YES in step S77, and the process proceeds to step S78. However, the processing after step S78 will be described later.
On the other hand, if the read record is not a closed record (NO in step S69) and is not a function record, that is, if it is an open record, step S77 is executed. In step S67, the process returns to step S67, and the subsequent processes are repeated.
In the above example, that is, in the example in which the pointer moves to the fifth line of the intermediate merge file in FIG. 7A, the record on the fifth line is an open record, so it is determined as NO in step S77. The processing is returned to step S67. In this case, the pointer moves to the sixth line of the intermediate merge file in FIG. 7A (step S67), and there is a record (YES in step S68). If it is determined as YES, the process proceeds to step S78.

In step S78, the abnormality detection unit 123 determines whether or not the time difference between the records of the previous function and the current function exceeds the drawer open permission time.
That is, the determination process in step S78 can be understood from the previous function that the current function has been executed while the drawer 25 is not closed (see NO in step S69) and the open state is maintained. Therefore, the time difference between the records of the previous function and the current function indicates the maintenance time of the drawer 25 in the open state. It is determined whether or not the maintenance time of the drawer 25 in the open state exceeds the drawer open permission time.

  If the maintenance time of the drawer 25 in the open state does not exceed the drawer open permission time, no drawer open abnormal time has occurred, so it is determined NO in step S78, and the process returns to step S65. The subsequent processing is repeated. That is, the drawer open permission time for the current function is searched, and the presence or absence of the drawer open abnormality time is detected based on the drawer open permission time.

On the other hand, if the maintenance time of the drawer 25 in the open state exceeds the drawer open permission time, it means that the drawer open abnormal time has occurred, so it is determined as YES in step S78, and the process Advances to step S79.
In step S79, the abnormality detection unit 123 increments the abnormality time detection count i by 1 (i = i + 1).
In step S80, the abnormality detection unit 123 determines whether or not the abnormal time detection count i is 1.
The case where the abnormal time detection count i is 1 means that the drawer open abnormal time is detected for the first time. Thus, when the abnormal time detection count i is 1, it is determined as YES in Step S80, and the process proceeds to Step S81. In step S81, the abnormality information output control unit 104 controls the printing unit 24 to print the detected drawer open abnormality time together with the header. That is, when the drawer open abnormal time is detected for the first time, not only the drawer open abnormal time detected for the first time but also the header is printed.

In the above example, that is, in the example in which the pointer moves from the 4th line to the 6th line of the intermediate merge file in FIG. 7A, the time difference between the previous function record and the current function record is 1 minute (09:22:02). 11-209: 21: 02.112). On the other hand, the drawer open permission time is 30 seconds. Therefore, since the drawer open abnormal time has occurred, it is detected, and it is determined as YES in Step S78, and the process proceeds to Step S79.
Then, the abnormal time detection count i is updated from 0 to 1 in step S79, and it is determined as YES in step S80. In the process of step S81, as shown in FIG. Along with the header “Report”, the drawer open abnormal time “2011/3/12 09:21 Ito Cash ... 60 seconds” is printed.

  On the other hand, when the abnormal time detection count i is not 1, it means that the drawer open abnormal time is detected for the second time or later. Therefore, in such a case, it is determined as NO in Step S80, and the process proceeds to Step S82. In step S82, the abnormality information output control unit 104 controls the printing unit 24 to print the detected drawer open abnormality time. That is, when the drawer open abnormality time is detected for the second time or later, printing of the header is unnecessary, and therefore only the detected drawer open abnormality time is printed.

In the foregoing, a series of processes for a pattern in which records arranged in a time series of an intermediate merge file do not sandwich a close record between two functions has been described.
Next, a series of processes for a pattern in which records arranged in a time series of an intermediate merge file sandwich a closed record between two functions will be described. However, since the process up to step S69 is the same, the description thereof is omitted.

  When the pointer advances to point to a closed record, it is determined as YES in step S69, and the process proceeds to step S70.

In step S <b> 70, the abnormality detection unit 123 determines whether the time difference between the records of the function and the close exceeds the drawer open permission time.
That is, the difference between the function and the closing time indicates the maintenance time of the drawer 25 in the open state. In the determination process of step S70, it is determined whether or not the maintenance time of the drawer 25 in the open state exceeds the drawer open permission time.

If the maintenance time of the drawer 25 in the open state does not exceed the drawer open permission time, no drawer open abnormality time has occurred, so it is determined NO in step S70, and the process proceeds to step S75 in FIG. .
In step S75, the abnormality detection unit 123 advances the pointer in the intermediate merge file by one record, returns the process to step S62, and repeats the subsequent processes.

On the other hand, when the maintenance time of the open state of the drawer 25 exceeds the drawer open permission time, it means that the drawer open abnormal time has occurred, so it is determined as YES in step S70, and the process Advances to step S71.
Note that the processes of steps S71 to S74 are the same as the processes of steps S79 to S82 described above, and thus the description thereof is omitted here.

When the above processing is repeatedly executed, the pointer advances and moves to the next (last) of the last record in the intermediate merge file. In such a case, it is determined as NO in Step S62 of FIG. 15, and the process proceeds to Step S76.
In step S76, the main control unit 101 deletes the intermediate merge file.
Thereby, the drawer open abnormal time detection process is completed.

Here, with reference to FIG. 17, the permission time search process of step S65 of FIG. 16 will be described.
FIG. 17 is a flowchart illustrating a detailed flow of the permission time search process in step S65 of FIG.
The permission time search process is executed when a function record is read from the intermediate merge file (YES in step S63 in FIG. 15 and step S64 in FIG. 16).

In step S101, the abnormality detection unit 123 sets the maximum value as the drawer open permission time. That is, the maximum value becomes the initial setting value.
In step S <b> 102, the abnormality detection unit 123 places a pointer at the top of the drawer opening / closing management table stored in the reference information storage unit 131.

In step S103, the abnormality detection unit 123 determines whether there is a record at the position indicated by the pointer.
If a record exists, it is determined as YES in step S103, and the process proceeds to step S104. In step S104, the abnormality detection unit 123 reads a record at the position indicated by the pointer in the drawer opening / closing management table.

  In step S105, the abnormality detection unit 123 determines the combination of the operator and the function in the record read from the intermediate margin file in the process of step S63, and the operator and the function in the record read from the drawer open / close management table in the process of step S104. It is determined whether the combinations match.

If they do not match, the record read in the process of step S104 does not include the target drawer open permission time, so it is determined as NO in step S105, and the process proceeds to step S106.
In step S106, the abnormality detection unit 123 advances the pointer position by one record. Thereafter, the process returns to step S103, and the subsequent processes are repeated.
That is, the loop processing of steps S103 (YES), S104, S105 (NO), and S106 is repeated, and the pointers are shifted sequentially.
If the combination of the operator and the function in the record read from the intermediate margin file in step S63 matches the combination of the operator and the function in the record read from the drawer open / close management table in step S104, In step S105, it is determined as YES, and the process proceeds to step S107.

In step S107, the abnormality detection unit 123 sets the drawer open permission time assigned to the operator in the record read from the drawer opening / closing management table in the process of step S104. As a result, the permission time search process ends.
Even when the above-described loop processing is repeated and the pointer moves to the end and there is no record that can be read, it is determined as NO in step S103, and the permitted time search processing is performed. Ends.
When the permission time search process ends, that is, when the process of step S65 of the drawer open abnormal time detection process of FIG. 16 ends, the process proceeds to step S66.

In the above, the drawer open abnormality time detection process of step S23 was demonstrated among the drawer abnormality detection processes of FIG.
When such a drawer open abnormality number detection process is completed, the process proceeds to a drawer open abnormality number detection process in step S24 of FIG.

Accordingly, with reference to FIG. 18, the drawer open abnormality frequency detection process will be described.
FIG. 18 is a flowchart for explaining an example of a detailed flow of the drawer open abnormality frequency detection process of step S24 in the drawer abnormality detection process of FIG.

In step S <b> 121, the history information acquisition unit 121 reads an operation history file record (operation history information) stored in the operation history information storage unit 132 for each operator.
In step S122, the history information acquisition unit 121 counts the number of records for each function.
In step S123, the history information acquisition unit 121 stores the total number of records for each operator-specific function in the integrated history information storage unit 134 as a frequency count file (see FIG. 7B).

In step S124, the abnormality detection unit 123 places a pointer at the beginning of the collection total file.
In step S125, the abnormality detection unit 123 sets the abnormality frequency detection count j to zero.

In step S126, the abnormality detection unit 123 determines whether or not a record exists at the position indicated by the pointer in the number counting file.
If the record does not exist, NO is determined in step S126, and the process proceeds to step S136. However, the processing after step S136 will be described later.
On the other hand, if a record exists, it is determined as YES in step S126, and the process proceeds to step S127.
In step S127, the abnormality detection unit 123 reads the record indicated by the pointer from the number counting file.
Specifically, for example, it is assumed that a point is arranged at the position of the first line from the top in the number counting file of FIG. In this case, the abnormality detection unit 123 records the first line, that is, a record indicating that the opening / closing frequency of the drawer 25 is “15” for the operator “Ito” in the “exchange” function. Read.

In step S128, the abnormality detection unit 123 searches the drawer opening / closing management table for the number of times the drawer is open for the operator and function corresponding to the record read in step S127.
Such a series of processing in step S128 is hereinafter referred to as “permission count search processing”. Details of the permitted number search process will be described later with reference to FIG.
For example, in the above-described example, that is, in the example in which the record in the first line of the counting number file in FIG. 7B is read, the drawer change management in FIG. 8 is performed because the “exchange” function and the operator are “Ito”. It is searched from the third row of the table that the drawer open permission count is 10 times.

  In step S129, the abnormality detection unit 123 determines whether or not the drawer open permission count is the maximum value.

That the drawer open permission count is the maximum value means that there is no limit to the number of times the drawer 25 can be opened and closed for the combination of the operator and the function corresponding to the record read in the process of step S127. In such a case, it is determined as YES in Step S129, and the process proceeds to Step S135.
In step S135, the abnormality detection unit 123 advances the pointer by one record. Thereafter, the process returns to step S126, and the subsequent processes are repeated.

  On the other hand, when the drawer open permission time is not the maximum value, it is determined as NO in Step S129, and the process proceeds to Step S130.

In step S130, the abnormality detection unit 123 determines whether or not the number of occurrences of the record exceeds the number of drawer open permits.
If the number of occurrences of the record does not exceed the number of times that the drawer is permitted to open, since the number of times when the drawer is open is not occurring, it is determined NO in step S130, and the process returns to step S135. Repeated.

On the other hand, if the number of occurrences of the record exceeds the number of permitted drawer opens, the number of abnormal drawer opens has occurred, so it is determined as YES in step S130, and the process proceeds to step S131. move on.
In step S131, the abnormality detection unit 123 increments the abnormality frequency detection count j by 1 (j = j + 1).
In step S <b> 132, the abnormality detection unit 123 determines whether or not the abnormality frequency detection count j is 1.
The case where the number of abnormal times detection j is 1 means that the detection of the number of drawer open abnormal times is the first time. As described above, when the abnormality frequency detection count j is 1, it is determined as YES in Step S132, and the process proceeds to Step S133.
In step S133, the abnormality information output control unit 104 controls the printing unit 24 to print the detected number of drawer open abnormalities together with the header. That is, when the detection of the number of drawer open abnormalities is the first time, not only the number of drawer open abnormalities detected at the first time but also the header is printed.

In the above example, that is, in the example in which the pointer is on the first line of the total number file in FIG. On the other hand, the drawer open permission count is 10 times. Therefore, since the number of drawer open abnormalities has occurred, it is detected, and it is determined as YES in Step S130, and the process proceeds to Step S131.
In step S131, the number of abnormal times detection j is updated from 0 to 1, and in step S132, it is determined to be YES. In the process of step S133, as shown in FIG. Along with the header “Report”, the number of drawer open abnormal times “2011/3/12 Ito Exchange 15” is printed.

  On the other hand, when the number of times of abnormality detection j is not 1, it means that the detection of the number of times of drawer open abnormality is the second time or later. Therefore, in such a case, it is determined as NO in Step S132, and the process proceeds to Step S134. In step S134, the abnormality information output control unit 104 controls the printing unit 24 to print the detected number of drawer open abnormalities. In other words, if the detection of the number of drawer open abnormalities is the second time or later, printing of the header is unnecessary, so only the detected number of drawer open abnormalities is printed.

When the above processing is repeatedly executed, the pointer advances and moves to the next (last) of the last record in the number counting file. In such a case, it is determined as NO in Step S126, and the process proceeds to Step S136.
In step S136, the main control unit 101 deletes the number counting file.
As a result, the drawer open abnormality number detection process is completed.

Here, with reference to FIG. 19, the permitted number searching process in step S128 of FIG. 18 will be described.
FIG. 19 is a flowchart for explaining the detailed flow of the permitted number search process in step S128 of FIG.
The permitted number searching process is executed when a record is read from the number counting file (see step S127).

In step S151, the abnormality detection unit 123 sets the maximum value as the number of drawer open permits. That is, the maximum value becomes the initial setting value.
In step S152, the abnormality detection unit 123 places a pointer at the head of the drawer opening / closing management table stored in the reference information storage unit 131.

In step S153, the abnormality detection unit 123 determines whether a record exists at the position indicated by the pointer.
If the record exists, it is determined as YES in Step S153, and the process proceeds to Step S154. In step S154, the abnormality detection unit 123 reads the record at the position indicated by the pointer in the drawer opening / closing management table.

  In step S155, the abnormality detection unit 123 sets the combination of the operator and the function in the record read from the number counting file in the process of step S127 and the operator and the function in the record read from the drawer opening / closing management table in the process of step S154. It is determined whether the combinations match.

If they do not match, the record read in the process of step S154 does not include the target drawer open permission count, so it is determined NO in step S155, and the process proceeds to step S156.
In step S156, the abnormality detection unit 123 advances the pointer position by one record. Thereafter, the process returns to step S153, and the subsequent processes are repeated.
That is, the loop processing of steps S153 (YES), S154, S155 (NO), and S156 is repeated, and the pointers are sequentially shifted.
If the combination of the operator and the function in the record read from the count number file in the process of step S155 matches the combination of the operator and the function in the record read from the drawer open / close management table in the process of step S154, In step S155, it is determined as YES, and the process proceeds to step S157.

In step S157, the abnormality detection unit 123 sets the number of drawer open permits assigned to the operator in the record read from the drawer open / close management table in step S154. As a result, the permitted number search process ends.
Even when the pointer moves to the end while the above loop processing is being repeated and there is no record that can be read, it is determined as NO in step S153, and the permitted number search processing is performed. Ends.
When the permitted number search process ends, that is, when the process of step S128 of the drawer open abnormality number detection process of FIG. 18 ends, the process proceeds to step S129.

  As described above, the sales data processing apparatus 10 needs to store the cash received from the customer, such as “cash”, “change preparation”, “exchange”, etc., in the drawer 25 or withdraw the change handed to the customer from the drawer 25. When a certain function is executed, the drawer 25 is automatically opened. However, the opened drawer 25 is not automatically closed but is closed by an operator's manual operation.

Since the opening and closing of the drawer 25 associated with such a function is a short time and the number of times of opening and closing is not frequent, the opening time of the drawer 25 is long, or the opening and closing frequency of the drawer 25 is many times There is a suspicion that the cash was withdrawn from the drawer 25 illegally.
Therefore, the standard opening time (drawer open permission time) and standard opening / closing frequency (drawer open permission times) of the drawer 25 required for each operator and for each function are set in advance. The sales data processing device 10 compares each of the standard opening time and the standard opening / closing frequency of the drawer 25 with each of the opening time and the opening / closing frequency as an operation history when the operator actually executes the function. Then, based on the result of the comparison, an operation history that is suspected of being illegally withdrawn from the drawer 25 is detected as an abnormal drawer operation.

Specifically, a drawer abnormality that detects, as an abnormal drawer operation, an operation that is suspected of illegally withdrawing cash from the drawer 25 to the sales data processing apparatus 10 that opens the drawer 25 in response to an operation by the operator. A detection device is built in the sales data processing device 10.
This drawer abnormality detection device includes a history information acquisition unit 121, a reference information acquisition unit 122, and an abnormality detection unit 123.
The history information acquisition unit 121 acquires the history of each operation (each function) for the sales data processing apparatus 10.
The reference information acquisition unit 122 is a standard for an operation specified from a history among standard operation standards (drawer open permission time and drawer open permission times) set in advance for each operation (for each function) that opens the drawer 25. Get operational criteria.
The abnormality detection unit 123 obtains a difference from the standard operation reference acquired by the reference information acquisition unit 122 for each operation specified from the history, and detects an abnormal drawer operation when there is a difference greater than or equal to a predetermined value. .
In this way, the operation history of the sales data processing apparatus 10 that is suspected of having been illegally withdrawn from the drawer 25 can be detected appropriately, accurately, and efficiently as an abnormal operation of the drawer 25. become.

  In addition, this invention is not limited to the above-mentioned embodiment, The deformation | transformation in the range which can achieve the objective of this invention, improvement, etc. are included in this invention.

For example, in the present embodiment, each function of the sales data processing apparatus is housed in one housing in the present embodiment, but this is not particularly necessary and may be distributed.
In particular, at least a part of the reference information storage unit 131 to the integrated history information storage unit 134 does not have to be provided in the storage unit 40 of the sales data processing device 10, and is not provided in a device (server or the like) external to the sales data processing device 10. You may make it provide.

In addition, when the drawer open permission time and the number of drawer open permission times do not exist in the reference information storage unit 131, the past average open time of the drawer 25 is determined from the operation history information for each operator and function in the reference information storage unit 131. The opening / closing frequency of the drawer 25 may be calculated and acquired as the drawer open permission time and the drawer open permission frequency.
In the above-described embodiment, the sales data processing apparatus 10 to which the present invention is applied has been described as an example, but the present invention is not particularly limited thereto. For example, the present invention can be applied to an electronic device having the drawer 25 in general.
