Description

  The present invention relates to a sales data processing apparatus and a program.

  In general, in stores such as supermarkets and convenience stores, sales data (product name, number, amount) registered in a sales data processing device such as an ECR (Electronic Cash Register) or POS (Point of sale) terminal, change, etc. Is recorded for each transaction as journal data, and other operation statuses are also recorded. Then, at the end of sales, the person in charge checks the operation status of the operator in detail while referring to the journal data to check in detail the operator's operation mistakes and unauthorized operations. Further, as a technique for preventing fraud, conventionally, when an operation for opening the drawer is performed, the face of the operator is photographed, and the journal data and photographing data at that time are captured via the network on the face of the external device side. A technique is disclosed in which the drawer is controlled so as not to open unless it is transferred and recorded in the image database (see Patent Document 1). Further, conventionally, when a receipt ID to be inspected is input to a search condition input area in the screen in a state where a moving image of the operator and the customer and the contents of the receipt are displayed in parallel on the same screen, A technique is disclosed in which receipt contents corresponding to a receipt ID and a moving image are read out and jump-displayed (see Patent Document 2).

(First embodiment)
First, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a block diagram showing basic components of an ECR (Electronic Cash Register) applied as a sales data processing apparatus.
This ECR (sales data processing apparatus) is separated into an ECR main unit 1 and a camera unit 2, and the ECR main unit 1 and the camera unit 2 are detachably connected via a cable 3. Has been. As a basic function (standard function) as the ECR, the ECR main unit 1 registers the input sales data for one transaction, and uses the denomination passed from the customer at the end of registration for one transaction. It has a sales data registration function that performs the appropriate type of tightening process. In the present embodiment, the ECR main unit 1 further generates an event code according to various key operations, drawer open / close, etc., and the event code is used as journal data to the camera unit 2. It has a function to transfer.

  The camera unit 2 captures a customer who is waiting for registration (waiting for payment), or a camera function for photographing a person in charge (operator) and its operation status, and reproduces an image captured by the camera function. However, various functions such as an operation inspection function for inspecting whether or not an unauthorized operation has been performed are modularized. The camera unit 2 is detachably connected to the ECR main unit 1 via a cable 3 and can be freely replaced at any time due to a failure or the like. The ECR main unit 1 and the camera unit 2 cooperate to perform various processes as necessary.

  The ECR main unit 1 has a CPU 11 as a core and is a central processing unit that controls the overall operation of the ECR main unit 1 according to various programs. The storage unit 12 includes, for example, a storage medium such as a ROM, a RAM, a flash memory, and a drive system thereof, and a program for realizing the present embodiment according to an operation procedure illustrated in FIGS. Stores various applications, database, character font data, etc. The above-mentioned storage medium is not limited to a built-in storage medium provided in a fixed manner, and may be a removable external storage medium. Program / data can be transmitted from another device to a wired transmission line. Alternatively, it may be installed in a storage medium via a wireless transmission path, or accessed by using a server that stores and manages programs / data. The memory 13 is a work area for temporarily storing various data necessary for the operation of the ECR main unit 1 such as timing data and flags.

  Further, the CPU 11 is connected with an operation unit 14, a scanner 15, an operator display unit 16, a printing unit 17, a drawer drive unit 18, and a COM port 19 as input / output peripheral devices via a bus line. The CPU 11 controls these operations according to the input / output program. The operation unit 14 has a keyboard on which various push button-type keys are arranged. On the keyboard, in addition to a numeric keypad (not shown), a registration key, a subtotal key, a cash / deposit key, and the like are arranged. In addition, a mode switch MS is provided.

  The mode switch MS is a rotary switch that switches various operation modes (program types) such as “registration (REG)”, “return (RF)”, “settlement (Z)” in accordance with the switching position. The registration key is a product key for instructing registration by product, for example, a PLU (Price Look Up) key, a department key, or the like. In a state where the CPU 11 is switched to the “registration (REG)” mode, the CPU 11 generates an event code corresponding to the operation according to various key operations, displays the input sales data, and displays the total sales. When the registration process for updating is executed and the cash / deposit key is pressed at the end of registration of one transaction, the drawer is released or a receipt is issued.

  The image scanner 15 includes, for example, an image sensor (image sensor) such as a CCD or a CMOS, and reads a bar code or a two-dimensional code attached to the product during a scanning operation for registering the product. The CPU 11 analyzes the image data photographed by the image scanner 15 to decode a barcode or the like and specify a product. The operator display unit 16 displays data about money and products, messages, and the like for a person in charge (operator), and is configured by, for example, a liquid crystal display or an organic EL (Electro Luminescence) display. The printing unit 17 is, for example, a non-impact printer such as thermal transfer or inkjet, or a dot impact printer, and performs receipt printing. The drawer drive unit 18 controls the opening / closing of the drawer 18A according to a key operation, and the CPU 11 generates a drawer open / close event according to the opening / closing of the drawer 18A. The COM port 19 is a serial port for connection with the camera unit unit 2.

  The camera unit 2 has a CPU 21 as a core, and is a central processing unit that controls the overall operation of the camera unit 2 according to various programs. The storage unit 22 includes, for example, a storage medium such as a ROM, a RAM, a flash memory, and a drive system thereof, and a program for realizing the present embodiment according to an operation procedure illustrated in FIGS. Stores various applications. The memory 23 is a work area for temporarily storing various data necessary for the operation of the camera unit 2.

  The CPU 21 is connected to the customer side display unit 24, the customer side camera 25, the operation side camera 26, the card interface unit 27, and the COM port 29, which are input / output peripheral devices, via a bus line. The CPU 21 controls these operations according to the program. The customer side display unit 24 has a screen facing the customer side for registration waiting (payment waiting) customers, and is composed of, for example, a 7-segment LED (light emitting diode) and the like. , Display the amount of deposit, etc. numerically.

  The customer-side camera 25 is disposed close to the customer display unit 24 and shoots mainly on the face of the customer waiting for registration. The operation-side camera 26 is a person in charge (operator) and its operation. This is a surveillance camera for photographing the situation, and for photographing the person in charge (operator) and the operation situation. Although details of the customer-side camera 25 and the operation-side camera 26 are not shown in the drawings, they have a lens unit, an image sensor, an A / D (analog / digital) conversion unit, and the like, and can capture moving images. The subject image from the lens unit is formed on an image sensor (CCD or CMOS), so that the subject can be photographed with high definition.

  The card interface unit 27 is inserted and connected to an SD card 28 as a recording medium, and various files to be described later are stored in the SD card 28. The camera unit 2 is provided with a lock (not shown) to prevent the SD card 28 inserted and connected to the card interface unit 27 from being stolen. For example, a dedicated key possessed by the person in charge is used. Then, the lock is opened and the SD card 28 is taken out. Further, the external recording medium is not limited to the SD card 28. The COM port 29 is a serial port for connection with the ECR main unit 1.

FIG. 2 is an external perspective view of the ECR (ECR main body unit portion 1) configured as described above as viewed obliquely from the front (customer side), and FIG. 3 is an ECR (ECR main body unit portion 1). It is an external view of the state seen from one side.
On the upper surface of the ECR main unit 1, an operator display unit 16 is disposed, and a keyboard and a mode switch MS constituting the operation unit 14 are disposed. A receipt issuing port (not shown) for taking out a receipt sent from the printing unit 17 is disposed on the upper surface of the ECR main unit 1.

  The camera unit unit 2 includes a housing 2A of the customer display unit 24 and a pole-shaped support member (supporting pole) 2B that supports the housing 2A. The support pole 2 </ b> B supports the housing 2 </ b> A of the customer display unit 24, and its lower end is fixed vertically on the back side of the ECR main unit 1. The upper end of the support pole 2B is mounted with a housing 2A of the customer display unit 24 so that the length of the housing 2A can be adjusted, and the housing 2A of the customer display unit 24 includes the support pole 2B. Can be rotated. That is, the height of the housing 2A and its orientation can be adjusted, and the height and orientation of the customer display unit 24 and the customer-side camera 25 can also be adjusted accordingly.

  As shown in FIGS. 2 and 3, the customer-side camera 25 is disposed close to one end portion (left end portion in the figure) of the customer display unit 24 on the front surface of the housing 2A. The angle of view is within a range where the customers in the registration queue can be photographed. The operation-side camera 26 is disposed at the upper end of the support pole 2B. The photographing direction is the operator direction, and the angle of view is a range in which the entire operation unit 14 and the face of the operator in operation can be photographed. ing. That is, the shooting direction and the angle of view of the operation side camera 26 are set so that the operator and the operation status thereof can be shot.

  FIG. 4 illustrates an operation image (moving image) obtained by photographing the person in charge (operator) and its operation status by the operation side camera 26, and shows a case where the operator puts in and out money with the drawer 18A opened. ing. In the above-described operation inspection function, when an operation image (moving image) photographed by the operation-side camera 26 is reproduced, it is performed using the operator display unit 16 as shown in FIG. An external monitor (display device as an external device) 4 may be connected to the ECR with a cable, and an operation image (moving image) may be reproduced on the external monitor 4.

FIG. 5 is a diagram showing various files stored on the camera unit 2 side (SD card 28).
The SD card 28 on the camera unit 2 side stores and manages a customer-side moving image file Y1, an operating-side moving image file Y2, an electronic journal file Y3, and the like. The customer side moving image file Y1 is a moving image file shot by the customer side camera 25, and the operation side moving image file Y2 is a moving image file shot by the operation side camera 26. The electronic journal file Y3 is a file that sequentially stores and manages the operation data as journal data for each operation. The electronic journal file Y3 is print data (operation data) that is sequentially printed on a receipt for each registration, that is, registered sales data and operation details. This is a file for storing and managing (for example, operation key type: key code: event code) as business record data (journal data). The electronic journal file Y3 sequentially stores and manages journal data for each chapter by inserting a chapter for operation identification at every operation timing when the operation is performed.

FIG. 6A shows the format of journal data (operation data) of the electronic journal file Y3.
One record of journal data (operation data) is data for one operation, and this set of records becomes journal data for one transaction, and a set of records for each transaction is a journal file (one day's worth). Settlement data). Here, the record of the journal data includes “mode”, “event code”, “chapter number”, “person name”, “year / month / day”, “hour / minute / second”, “series No.” as shown in the figure. , “Amount”, and “Journal data”. The “mode” is an operation mode such as “registration (REG)” switched by the mode switch MS. “Event code” indicates the type (key code) of the operation key.

  The “chapter number” is a chapter number (for example, a serial number), and the camera unit 2 inserts and stores the chapter number at the operation timing for each operation. That is, in the registration mode which is switched to “registration (REG)” by the mode switch MS, the chapter number is inserted at the operation timing when the key code corresponding to the operation key is input every time any operation is performed. I try to remember it. “Journal data” is print data printed on a receipt as described above.

FIG. 6B is a diagram showing the format of the operation-side moving image file Y2.
The operation side moving image file Y2 is an operation image (moving image file) photographed by the operation side camera 26. The transaction (1) scene, the transaction (2) scene, the transaction (3) scene, The transaction is sequentially stored and managed for each transaction, such as “Scene of transaction (4)”, and the operation timing for each operation described above, that is, the chapter number is inserted into the journal data in this operation image (video file). The same chapter number is inserted and stored at the stored timing. In the illustrated example, “0001” and “0002” to “0005” are inserted and stored as chapter numbers in “transaction (1) scene”, and chapter numbers are stored in “transaction (2) scene”. In this case, “0006” to “0010” are inserted and stored.

When the operation image (moving image file) in the operation side moving image file Y2 is reproduced, fast-forward reproduction / slow reproduction / reverse reproduction can be performed. In this case, on the camera unit 2 side, when an operation inspection function for inspecting whether or not an unauthorized operation has been performed is activated by a responsible person, the contents of the operation side moving image file Y2 and the electronic journal file Y3 are operated in synchronization. The display unit 16 or the external monitor 4 is mainly composed of the display mode for simultaneous display to be displayed in parallel on the display unit 16 for the operator or the external monitor 4 and the contents of either the operation side moving image file Y2 or the electronic journal file Y3. The main display mode to be displayed can be arbitrarily selected.
In other words, referring to “ON / OFF” of a synchronous display flag (not shown) arbitrarily set by a user operation in advance, the contents of the operation side moving image file Y2 and the electronic journal file Y3 are synchronously displayed in parallel. The display mode can be switched to the main display mode in which either one of the contents is displayed as the main.

FIG. 7A is a diagram showing a display example in which the contents of the operation-side moving image file Y2 and the electronic journal file Y3 are displayed in parallel in the operation inspection function.
When the above-described synchronous display flag is “ON” (simultaneous display mode), the camera unit 2 sequentially reads out the operation images (operation movies) recorded in the operation side movie file Y2 and displays them on the display screen. In addition to starting the reproduction operation, the contents of the electronic journal file Y3 are sequentially displayed in the screen simultaneously in conjunction with the reproduction of the operation moving image. In the figure, the left screen shows the operation video playback screen OP, and the right screen shows the journal data playback screen JR. The operation video playback screen OP and the journal data playback screen JR are simultaneously displayed. Playback is displayed as it progresses (synchronized playback display). That is, in order to display the operation video having the same content and the journal data in synchronization (appearing simultaneously), the journal data is sequentially scroll-displayed in conjunction with the sequential reproduction of the operation video.

FIG. 7 (2) shows the case where the contents of one of the operation side moving image file Y2 and the electronic journal file Y3 of the operation side moving image file Y3 and the electronic journal file Y3 are mainly displayed in the operation inspection function. It is the figure which showed the example of a display in the main body display mode which displays the content of the moving image file Y2 as a main body.
When the above-mentioned synchronous display flag is “off” (subject display mode), the camera unit unit 2 stores the operation-side moving image file Y2 in the operation-side moving image file Y2 if it is specified to be displayed as the main component. A reproduction operation for sequentially reading recorded operation images (operation moving images) and displaying them on the display screen is started.

  Then, when a predetermined operation (synchronization confirmation operation described later) is performed during the reproduction operation, the electronic journal file Y3 is searched based on the chapter inserted in the operation image currently reproduced, and the corresponding chapter is retrieved. The journal data in which (the same chapter) is inserted is read, and this journal data is displayed in a superimposed manner (superimposed display) in synchronization with the operation image being reproduced. In the figure, the display content at the upper left indicates journal data, and the deposit and change amount are recorded as journal data at the timing when the cash / deposit key is operated after the number of deposits is counted (when the drawer 18A is released). The case where it is displayed in a superimposed manner is shown.

When the above-mentioned synchronous display flag is “off” (subject display mode), contrary to the case of FIG. 7 (2), when displaying the contents of the electronic journal file Y3 as a subject,
When the reproduction operation for sequentially reading the journal data stored in the electronic journal file Y3 and displaying it on the display screen is started, and when a predetermined operation (synchronization confirmation operation described later) is performed during the reproduction operation, The operation side moving image file Y2 is searched based on the chapter inserted in the journal data being reproduced, the operation image in which the corresponding chapter (the same chapter) is inserted is read out, and synchronized with the journal data being reproduced. The operation image is superimposed (superimposed).

  Next, the operation concept of ECR in the first embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. Further, it is possible to sequentially execute the operation according to the above-described program code transmitted via a transmission medium such as a network. In other words, in addition to the recording medium, an operation unique to the present embodiment can be executed using a program / data supplied externally via a transmission medium.

FIG. 8 is a flowchart showing an overview of the overall operation of the ECR that is started when the power is turned on.
First, the CPU 11 of the ECR main unit 1 executes an initialization process for clearing various memories in response to power-on (step A1). Then, a moving image file name (for example, data in which a serial number is added to the date) is generated and set in the operation side moving image file Y2 (step A2), and the operation side camera 26 is activated to start recording (step S2). A3). In this state, it is checked whether the mode switch MS is switched to the “registration (REG)” mode (step A4), whether the mode switch MS is switched to the “settlement (Z)” mode (step A5), and the like. It is checked whether the mode has been switched (step A6), or whether a power-off operation has been performed (step A7). Now, when the registration mode is switched (YES in step A4), the process proceeds to a registration process for registering sales data every time a registration operation is performed (step A8).

FIG. 9 is a flowchart for explaining the registration process (step A8 in FIG. 8) in detail. The ECR main unit 1 performs various processes in cooperation with the camera unit 2 as necessary.
First, the CPU 11 of the ECR main body unit 1 confirms whether a registration operation has been performed, that is, whether a scanning operation has been performed by the scanner 15 to read a barcode or the like from a product, or a product key or the like after inputting the number of value data. It is checked whether the registration key has been operated (step B1), whether a closing key such as a cash / deposit key has been operated at the end of registration for one transaction (step B6), or whether other keys have been operated. To investigate (step B11).

  If a registration operation is performed (YES in step B1), the process proceeds to a product registration process (step B2), and the input product name and unit are displayed on the operator display unit 16 and the customer display unit 24. Based on the input sales data, the contents (sales data) of the product total file and department total file (not shown) are updated. In this case, by transferring display data from the ECR main unit 1 to the camera unit 2 side, the product name and unit are displayed on the customer display 24. Then, after updating the subtotal amount for one transaction (step B3), a chapter (serial number) corresponding to the current operation is generated (step B4).

  Then, the operation data of this transaction is stored as journal data in the electronic journal file Y3 together with the generated chapter, and the same chapter is recorded at the current recording position of the operation side moving image file Y2 (step B5). That is, the same chapter is recorded in the electronic journal file Y3 and the operation-side moving image file Y2 at the timing when the key code corresponding to the operation key is input (operation timing) (hereinafter the same). And it returns to the above-mentioned step B1, and repeats the above-mentioned operation | movement every time registration operation is performed hereafter.

  When another operation is performed (YES in step B11), for example, when a subtotal key, a correction key, or the like is operated, the subtotal amount is displayed for the operator as processing corresponding to the operation (step B12). The display unit 16 and the customer display unit 24 display the data or correct the input data. Then, the process proceeds to step B4 described above, and after generating a chapter (serial number) according to the current operation, the operation data in the current transaction is stored as journal data in the electronic journal file Y3 together with the generated chapter. Are recorded at the current recording position of the operation-side moving image file Y2 (step B5).

  In addition, when a closing key such as a cash / custody key is operated at the end of registration for one transaction (YES in step B6), processing for updating the transaction total is performed according to the denomination passed from the customer. If the operated closing key is a cash / deposit key, a closing process is performed to open the drawer (step B7), and the printing unit 17 is driven to print the sales data on the receipt and issue the receipt. (Step B8). Then, after generating a chapter (serial number) according to the current operation (step B9), the operation data in the current transaction is stored as journal data in the electronic journal file Y3 together with the generated chapter, and the same chapter is stored. Recording is performed at the current recording position of the operation-side moving image file Y2 (step B10). Thereafter, the flow of FIG. 9 is exited.

  As a result, when the registration process for one transaction (step A8 in FIG. 8) ends, the process returns to step A4 described above. On the other hand, when the mode switch MS is switched to another mode other than “registration (REG)” and “settlement (Z)”, for example, “return (RF)” mode (YES in step A7), the mode For example, a return process (returned goods process) or the like is performed as a process in accordance with (Step A9). Then, a chapter (serial number) is generated in accordance with the current operation (step A10), the current operation data is stored as journal data in the electronic journal file Y3 together with the generated chapter, and the same chapter is stored on the operation side moving image. Recording is performed at the current recording position of the file Y2 (step A11). Thereafter, the process returns to step A4 described above.

  Further, for example, when the business of the day is over and the mode switch MS is switched to the “checkout (Z)” mode (YES in step A5), a checkout process for updating the contents of a transaction total file (not shown) is executed. (Step A12), a chapter (serial number) is generated according to the current operation (Step A13), and the current operation data is stored as journal data in the electronic journal file Y3 together with the generated chapter. The chapter is recorded at the current recording position of the operation-side moving image file Y2 (step A14). Then, it is checked whether or not an operation for instructing an operation inspection has been performed (step A15). If the instruction operation is not performed (NO in step A15), the process returns to the above step A4, but when the instruction operation is performed, (YES in step A15) After performing an operation inspection process described later (step A16), the process returns to step A4 described above. When a power-off operation is performed (YES in step A7), a predetermined power-off process is executed (step A17), the operation camera 26 is stopped (step A18), and the flow of FIG. 8 ends. It becomes.

10 and 11 are flowcharts for explaining the operation inspection process (step A16 in FIG. 8) in detail. The ECR main unit 1 performs various processes in cooperation with the camera unit 2 as necessary.
First, when the CPU 11 of the ECR main body unit 1 performs an operation of specifying the inspection target file name, the CPU 11 transfers the specified file name to the camera unit 2 (step C1 in FIG. 10). On the camera unit unit 2 side, the specified operation moving image to be inspected is acquired from the operation side moving image file Y2 (step C2), and the inspection target journal data is acquired from the electronic journal file Y3 (step C3).

  Then, whether the synchronous display flag (not shown) arbitrarily set by the user operation is “ON”, that is, the contents of the operation side moving image file Y2 and the electronic journal file Y3 are displayed in parallel and displayed in parallel. It is checked whether the display mode is designated (step C4). Now, in the simultaneous display mode in which the synchronous display flag is “ON” (YES in step C4), the reproduction of the operation moving image acquired as the inspection target and the journal data is started simultaneously, and the display for the operator is performed. The operation moving image and the journal data are displayed in parallel on the display screen of the unit 16 or the external monitor 4 (step C5). As a result, as shown in FIG. 7A, a moving image file (operation moving image) is displayed on the reproduction screen OP, and journal data is displayed on the reproduction screen JR. In this case, the operation moving image and the journal data are reproduced simultaneously while detecting the coincidence between the chapter (serial number) inserted in the operation moving image and the chapter inserted in the journal data.

  In this state, the process moves to step C14 and subsequent steps in FIG. 11 and moves to a process corresponding to the operation (steps C14 to C19). That is, when an operation for instructing a pause is performed in a state where the operation moving image and the journal data are being reproduced at the same time (YES in Step C14), the reproduction operation of the operation moving image and the journal data is suspended ( Step C15). When an operation for instructing fast forward playback / slow playback / reverse playback is performed (YES in step C16), the playback operation of the operation video and journal data is controlled to perform fast forward playback / slow playback / reverse playback. When an operation for instructing other playback control is performed (step C18), such as canceling the pause, canceling the fast-forward playback / slow playback / reverse playback, etc. (YES in step C18) The reproduction operation is controlled in accordance with (Step C19).

  At the end of playback, that is, when a user operation for instructing the end of playback is performed or when it is detected that playback has been completed to the end of the operation video and journal data (YES in step C20), 10 and FIG. 11 are exited, but if the reproduction is not finished (NO in Step C20), it is checked whether the synchronous display flag is “ON” (Step C21). If the synchronous display flag remains “ON” in the simultaneous display mode (YES in step C21), the process returns to the above-described steps C14 to C19 to perform processing according to the operation.

  On the other hand, when the synchronous display flag is “off”, that is, when the subject display mode in which the contents of either the operation-side moving image file Y2 or the electronic journal file Y3 are displayed as the subject is designated ( Whether or not the operation side moving image file Y2 has been selected as the subject to be displayed is checked (step C6). In addition, when selecting the subject of the subject display, it may be arbitrarily selected by a user operation during the execution of the operation inspection process, but it is arbitrarily selected and set in advance before the execution of the operation inspection process. It may be left. Here, when the content of the operation side moving image file Y2 is instructed as the subject of the main display (YES in Step C6), the content of the operation side moving image file Y2 is acquired and the reproduction is started (Step C7). ) If the content of the electronic journal file Y3 is instructed as a subject to be displayed (NO in step C6), the content of the electronic journal file Y3 is acquired and its reproduction is started (step C8). In the case of the display example of FIG. 7 (2), the state in which the content of the operation side moving image file Y2 is being reproduced is shown.

  In this state, the presence / absence of a synchronization confirmation operation is checked (step C9 in FIG. 11). Here, the synchronization confirmation operation refers to reading and synchronizing the other content that matches the chapter being played back in the main display mode in which either one of the operation side moving image file Y2 or the electronic journal file Y3 is displayed as the main component. Operation for instructing display, for example, a double-click operation on the screen when a mouse is provided as a pointing device, and a double-tap on the screen when a touch screen is provided It is an operation. If the synchronization confirmation operation is not performed (NO in step C9), the process proceeds to the above-described operation (steps C14 to C19).

  On the other hand, when a synchronization confirmation operation is performed in the main display mode (YES in step C9), a chapter is detected from one content (operation image / journal data) currently being reproduced (step C10), and the detected chapter is displayed. Based on this, the other content (journal data / operation image) is searched (step C11), and the journal data / operation image having the same chapter is obtained (step C12). Then, the acquired journal data / operation image is displayed in a superimposed manner on the currently reproduced screen (step C13). Thereafter, the process proceeds to the above-described operation (steps C14 to C19).

  In the case of the display example in FIG. 7B, when the journal data is superimposed on the operation image reproduction screen OP, the above-described synchronization confirmation operation (for example, double-clicking) is performed on the operation image reproduction screen OP. When an operation or a double tap operation) is performed, the journal data in the transaction scene being reproduced is jumped, and the journal data is displayed superimposed on the reproduction screen OP. On the other hand, when a synchronization confirmation operation is performed on the journal data reproduction screen, a jump is made to a moving image scene in which the journal data is input, and the moving image scene (operation image) is superimposed and displayed. In this case, the superimposed display is continued until the next operation is performed. However, the present invention is not limited to this, and the superimposed display may be continued until the cancellation of the superimposed display is instructed. For example, when fast-forward playback / slow playback / reverse-play playback of an operation image is instructed in the superimposed display state, the contents of the journal data are also synchronized with the playback operation of the operation image (while detecting matching of chapters). Fast forward playback / slow playback / reverse playback may be performed. Thereafter, the above-described operation is repeated until the end of reproduction is detected.

  As described above, in the first embodiment, when a predetermined operation is performed during a reproduction operation for reproducing and displaying the operation image recorded in the operation side moving image file Y2, the operation image is inserted into the operation image currently being reproduced. The electronic journal file Y3 is searched based on the chapters being read, the journal data in which the corresponding chapters are inserted is read, and the journal data is displayed in synchronization with the operation image being played back. When a predetermined operation is performed during a reproduction operation for reproducing and displaying journal data stored in the journal file Y3, the operation side moving image file Y2 is searched based on the chapter inserted in the currently reproduced journal data. The operation image with the corresponding chapter inserted is read, and the operation image is synchronized with the journal data being played back. When the user (inspector) inspects whether the correct operation has been performed, the operation image and the journal data can be checked in association with each other. This makes it easy to find a multi-faceted and efficient inspection, enables more accurate inspections, and reduces the burden on the inspector.

  Further, the timing at which the key code corresponding to the operation key is input is set as the operation timing, the chapter is inserted and stored in the electronic journal file Y3, and the same chapter is stored in the operation side moving image file Y2 at the timing at which the chapter is inserted into the electronic journal file Y3. The operation image and the journal data can be synchronized via the chapter, and the synchronization display between the operation image and the journal data can be easily performed by detecting the match / mismatch of the chapters. It can be carried out. In addition, by using chapters as serial numbers, the number of operations in one transaction, the number of operations in one day transaction, and the like can be easily obtained, and various types of management are facilitated.

  In addition, it is now possible to select whether to display the operation image synchronously during the playback operation with the journal data as the main object or to display the journal data synchronously during the playback operation with the operation image as the main object. In addition to being able to display the entire screen, it is possible to perform inspection while appropriately changing the subject as required, and it is possible to change the viewpoint and discover a new illegal operation.

  Synchronous display for displaying journal data simultaneously in sync with the playback operation of the operation image can be set as desired so that the inspector can execute synchronous display as needed. .

  The operation-side camera 26 is disposed in the vicinity of the customer-side display unit 24, and its shooting direction and angle of view are set so that the operator and its operation status can be shot. In addition, the operation status can be photographed from above the operation unit 14.

(Second Embodiment)
A second embodiment of the present invention will be described below with reference to FIGS.
In the above-described first embodiment, the case where the present invention is applied to an ECR alone has been shown. However, in the second embodiment, the present invention is applied to a sales data processing system in which the ECR and a management apparatus (server apparatus) are connected by communication. This is the case. Here, in both the embodiments, the same or the same names are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIG. 12 is a block diagram showing a sales data processing system.
The sales data processing system is a LAN system in which a plurality of ECRs 100 installed in a store are connected to a management device (server device) 200 via a LAN (private private line) 300. The system is connected to a sales data processing system of another affiliated store B via the Internet 400 and can communicate therewith. The configuration of the ECR 100 is basically the same as the configuration shown in FIG. 1, but in the second embodiment, a LAN communication unit that further transmits and receives data to and from the management device (server device) 200. 101. The management device (server device) 200 is a personal computer (PC), and the configuration thereof is not shown. However, in addition to the CPU, storage unit, display unit, and operation unit, data is transmitted to and received from the ECR 100. A LAN communication unit 201 is provided.

FIG. 13 is a flowchart showing an outline of the operation on the management apparatus (server apparatus) 200 side.
First, the server apparatus 200 designates one of a plurality of ECRs 100 connected to the LAN as a processing target (step D1), and then requests the designated ECR 100 to transmit an operation video and journal data (step D2). ). Here, on the ECR 100 side, basically the same operation as the operation shown in FIGS. 7 and 8 is executed, but the difference is that instead of Step A15 and Step A16 in FIG. When a data transmission request is received, a process for transmitting the operation moving image and journal data to the server device 200 in response thereto is performed. That is, in the second embodiment, the operation inspection process is not performed, and the process is left to the server device 200 side. Note that the transmission process in response to a request from the server apparatus 200 is not limited to the payment mode, and may be executed in other modes. In addition, the server device 200 may request the data transmission by designating the inspection target, but may request the transmission of the operation video and journal data for the current day at the end of the business day. .

  When the server apparatus 200 receives the operation video and journal data from the designated ECR 100 side (step D3), the server apparatus 200 starts an operation inspection process based on the operation video and journal data (step D4). Here, the server apparatus 200 performs basically the same processing as the operation inspection processing illustrated in FIGS. 10 and 11. In other words, after starting the playback operation to play back the operation video and journal data at the same time, each time an operation requiring attention is detected with reference to the journal data, an icon corresponding to the type of operation requiring attention is operated at the detection timing. Performs an operation to generate an alarm sound while superimposing it on the moving image. In this way, when the inspection process for one ECR 100 is completed (step D4), it is checked whether all ECRs 100 have been specified (step D5). If unspecified ECRs 100 remain (NO in step D5). Returning to the above-described step D1, the above-described operation is repeated.

  As described above, in the second embodiment, the server apparatus 200 requests the ECR 100 to transmit the operation video and journal data, and in response to the operation video and journal data transmitted from the ECR 100 side in response thereto, the operation inspection is performed. Since the process is executed, as in the first embodiment described above, the user (inspector) associates the operation image with the journal data when inspecting whether the correct operation has been performed. This makes it easy to detect unauthorized operations, realizes multifaceted and efficient inspections, enables more accurate inspections, and reduces the burden on inspectors. Become.

  In addition, the second embodiment has the same effects as those of the first embodiment described above. That is, also in the second embodiment, the operation image and the journal data can be synchronized via the chapter, and the synchronization display of the operation image and the journal data can be easily performed by detecting the match / mismatch of the chapter. It can be carried out. In addition, by using chapters as serial numbers, the number of operations in one transaction, the number of operations in one day transaction, and the like can be easily obtained, and various types of management are facilitated. In addition, since it is possible to arbitrarily set whether or not to perform synchronous display that displays journal data simultaneously in synchronization with the playback operation of the operation image, the user such as the person in charge can display synchronous display as necessary. Can be executed. In addition to displaying the subject of inspection on the entire screen, it is possible to perform inspection while appropriately changing the subject as necessary, and it is possible to find a new illegal operation by changing the viewpoint.

  In the second embodiment described above, the present invention is applied to a LAN system in which the ECR 100 and the server apparatus 200 are connected via a LAN (private private line) 300, but is inserted and connected to the card interface unit 27. The operation side moving image file Y2 and the electronic journal file Y3 may be compressed and stored in a predetermined format in the SD card 28, and the SD card 28 may be inserted and connected to a PC (management apparatus). That is, the operating-side moving image file Y2 and the electronic journal file Y3 may be supplied to the PC (management device) side via a portable external storage medium such as the SD card 28. For example, the operation side moving image file Y2 and the electronic journal file Y3 may be collectively supplied to the PC side via the SD card 28 at the end of the business day. In this case, on the PC side, the operation inspection process may be executed based on the operation side moving image file Y2 and the electronic journal file Y3 in the SD card 28.

  Further, in each of the above-described embodiments, the timing at which the key code corresponding to the operation key is input is used as the operation timing, the chapter is inserted and stored in the electronic journal file Y3, and the operation is performed at the timing at which the chapter is inserted into the electronic journal file Y3. Although the same chapter is inserted and stored in the side moving image file Y2, the present invention is not limited to this, and the fact that the position of the operation finger has changed in the operation image by analyzing the operation image taken by the operation side camera 26 is confirmed. The detected timing, for example, the timing at which a new key operation such as a PLU key or subtotal key is detected is used as the operation timing, and the chapter is inserted and stored in the operation-side moving image file Y2, and this chapter is inserted and stored. Insert and store the same chapter in the electronic journal file Y3 at the timing It may be allowed. This eliminates the need to send the key code from the ECR main unit 1 to the camera unit 2 for each operation, and allows the chapter to be inserted by the operation on the camera unit 2 side.

  Further, in each of the above-described embodiments, when the subject to be displayed is selected, it may be arbitrarily selected by a user operation during the execution of the operation inspection process, or may be arbitrarily selected before the operation inspection process is executed. However, in addition to steps C6 to C8 in FIG. 10, any one of steps C9 to C21 in FIG. 11 may be provided to make it possible to arbitrarily select the subject to be displayed. It may be. This makes it possible to arbitrarily switch the subject of the main display even after the display is started.

  Further, the “apparatus” and “unit” shown in each of the above-described embodiments may be separated into a plurality of cases by function, and are not limited to a single case. In addition, each step described in the above-described flowchart is not limited to time-series processing, and a plurality of steps may be processed in parallel or separately.

The embodiment of the present invention has been described above. However, the present invention is not limited to this, and includes the invention described in the claims and the equivalent scope thereof.
