DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. FIG. 1 is a block diagram showing the overall configuration of the ECR. The CPU 1 has a calculation unit 1-1 and a control unit 1-2, and R
A central processing unit that controls the overall operation of the ECR according to various programs in the OM2, and an input unit 3, a display unit 4, a printing unit 5, a drawer 6, and a clock 7 as peripheral devices thereof are connected to the CPU 1, respectively. Has been done, R
These input / output operations are controlled according to the input / output control program in the OM2.

The input unit 3 has a numeric key A on its keyboard.
In addition to K, department key, PLU (price look up) key, cash / deposit key, +,-, for four arithmetic operations
It is configured to have various function keys BK such as ÷ and × keys, and a mode switch MS. The mode switch MS has “REG (registration)”, “OFF (power off)”, “RF (return)”, depending on its switching position.
The modes of "PGM (setting)", "C (computer)", "Z (settlement)", and "X (check)" are switched. Here, the computer mode is a mode peculiar to the present embodiment, and is a mode for performing calculation processing (four arithmetic operations) different from the normal registration processing. Now, when the sales data is input from the input unit 3 in the registration mode in which the mode switch MS is switched to the REG position, the CPU 1 causes the display unit 4 to display and output the sales data, or the receipt of the printing unit 5. / Prints out to the journal, further updates the value of the subtotal register 8-1 in the RAM 8, and performs the registration process of updating the contents of the various totalizers 8-3.

The RAM 8 includes a subtotal register 8-1, a calculation result memory 8-2, various totalizers 8-3, a registered switching number counter 8-4, a non-registered switching number counter 8-5, and a computer mode switching condition memory 8. With the configuration having -6, the subtotal register 8-1 is a register that stores subtotal data for one transaction, and its value is updated every time sales data is input from the input unit 3. The calculation result memory 8-2 is a work memory for calculation processing used when the mode is switched to the computer mode by the mode switch MS, and the cash / deposit key for closing one transaction is closed and the key is operated. Before the calculation, that is, when the registration mode is switched to the computer mode during the registration, the contents of the subtotal register 8-1 are transferred to the calculation result memory 8-2 as they are, and after the calculation processing, the calculation result memory 8 The contents of -2 are transferred to the subtotal register 8-1. Note that when the registration mode or another mode is switched to the computer mode after the closing of one transaction, etc., not during such registration, the numerical data entered from the input unit 3 is stored in the calculation result memory. 8-2 is written and processed.

The various totalizers 8-3 are composed of totalizers such as a departmental totalizer and a person-in-charge totalizer, and each time sales data is input from the input unit 3, the sales data corresponding to the product is updated. Is done. The switching count counter during registration 8-4 counts the switching count when the registration mode is switched to the computer mode during registration before the registration of one transaction is completed, and the non-registration switching count counter 8-4. -5 counts the number of times of switching when the mode is switched to the computer mode during non-registration such as after the registration of one transaction is completed. The content of is printed out as computer mode switching history information when the inspection report is issued. The computer mode switching condition memory 8-6 stores the switching condition to the computer mode indicating whether to permit switching to the computer mode for each person in charge, and the content thereof is set arbitrarily. Here, when the computer 1 is switched to the computer mode, the CPU 1 refers to the computer mode switching condition memory 8-6 to determine whether or not the current person in charge satisfies the switching condition, and as a result, the condition is satisfied. Only in this case, switching the computer mode is valid.

FIG. 2 shows a computer mode switching condition memory 8-6.
The contents of the computer mode switching condition memory 8
-6 stores "switchability", "password", and "switchable period (date and time, day of the week)" for each Clark No (person in charge).
Here, the “switchability” has the highest priority over other switching conditions, and the switchability is designated only to the skilled person or the like. In addition, the "PIN code" is collated with this input data when the PIN number unique to the person in charge (numerical data different from the person in charge) is input when switching to the computer mode. It is a condition following "possibility". The last "switchable period" indicates the period condition that the person in charge can switch depending on the date and time and the day of the week.
Even if the above two conditions are satisfied, if the condition for this period is not satisfied, the switching of the computer mode is invalid.

Next, the operation of this embodiment will be described with reference to the flowcharts shown in FIGS. FIG. 3 is a flowchart showing an outline of the operation of the entire ECR which is started when the power is turned on. First, the switching state of the mode switch MS is detected (steps A1 and A2). here,
If the mode is switched to another mode other than the registration mode and the computer mode, the processing corresponding to the mode (for example,
Inspection processing, setting processing, etc.) are performed (step A3).

Now, when the registration mode is switched to (step A1), the CPU 1 inputs the sales data every time the registration input for product registration is performed from the input section 3 in this registration mode (step A4). The registration process is performed based on (step A5). That is, the CPU 1 adds the sales amount of this time to the subtotal register 8-1 based on the input sales data, updates the contents of the various totalizers 8-3, and further displays and prints out the registration contents of this time. To do. Then, when a closing operation for ending the registration of one transaction is performed (step A6), finalizing processing is performed to open the drawer 6, or change calculation or the like is performed (step A7). After issuing the receipt, the process returns to the process (step A1) of detecting the switching state of the mode switch MS.

When the mode switch MS has switched to the computer mode, the fact is detected in step A2 and the process proceeds to step A9 to perform the computer mode switching process. FIG. 4 is a flowchart showing this computer mode switching processing. First, the computer mode switching condition memory 8 is based on the current Clark No. which has been input in advance.
-6 is searched (step B1), and it is determined whether or not the person in charge is authorized to switch to the computer mode based on the "switchability" information corresponding to the Clark No (step B2). Here, if you are an authorized person,
A message prompting you to enter the No is displayed. If you enter the password in response to this, the entered password is compared with the contents of the computer mode switching condition memory 8-6 (step B3) and the password is entered. It is checked whether the Nos match (step B4). If they match, the current timekeeping information is further read from the clock 7, and this is checked against the contents of the computer mode switching condition memory 8-6 (step B).
5). As a result, if it is within the switchable period, it is determined that all the conditions are satisfied, and the process is exited. On the other hand, if it is determined in step B2 that the person in charge is not permitted to switch, or if the password is different even if the person is permitted (step B4), or if it is not within the switchable period (step B4). In B6), the display indicating that switching to the computer mode is not possible is displayed (step B7), and the switch-disabled flag is turned on (step B8).

When the computer mode switching process is performed in this way, the process proceeds to step A10 in FIG. 3 to check whether the switch disable flag is turned on, and if it is turned on, then turn it off. (Step A12),
The process returns to the mode determination process (step A1), but if the switch-disabled flag is turned on, the process proceeds to the computer process (step A11).

FIG. 5 is a flow chart showing computer processing. First, it is checked whether or not registration is in progress (step C).
1). In other words, before closing the registration of one transaction, check whether it was switched to computer mode, if it is registered,
The contents of the subtotal register 8-1 are taken into the calculation result memory 8-2 and copied (step C2). Then, it waits until the numerical data is input from the input unit 3 and the four arithmetic operation keys are operated (step C3). Here, when the four arithmetic operation keys are input, the four arithmetic operation processing is performed according to the key and the processing result is transferred to the calculation result memory 8-2 (step C4). In this case, since the contents of the subtotal register 8-1 are copied to the calculation result memory 8-2 during registration, it is possible to perform a calculation such as a discount or a discount on the subtotal data. The calculation result is stored in the calculation result memory 8-2. In addition, if it is not switched to computer mode during registration,
It is possible to perform four arithmetic operations that are not directly related to registration, and the operation results are stored in the calculation result memory 8-2. The contents of the calculation result memory 8-2 are displayed and output (step C5), and the calculation procedure is saved in the RAM 8 as an operation history (step C6).

When such a calculation process is completed, the process proceeds to step A13 in FIG. 13 and it is checked whether or not the mode is switched to the computer mode during registration. If the computer mode is switched during registration, the computer process is continued (step A11) until the mode is switched back to the registration mode (step A14). In such a computer mode, the operation of the closing key, the operation of the deposit key and the like cannot be accepted, and therefore the opening of the drawer 6 is prohibited. Here, when the mode is switched to the registration mode, first, the calculation result memory 8-
The contents of 2 are transferred to the subtotal register 8-1 (step A15). As a result, the content of the subtotal register 8-1 becomes the value after discounting or discounting is performed on the subtotal in the computer mode. Next, after the normal finalizing process (step A16) and the receipt issuing process (step A17) are performed, the information indicating that the computer mode has been switched is printed in the journal (step A18).
In this case, the key operation procedure in the computer mode is printed as a journal as an operation history. Then, an increment process of adding "1" to the value of the switching number counter 8-4 during registration is performed (step A19). Then step A
Return to 1.

On the other hand, if the mode is switched to the computer mode while not being registered, the process proceeds from step A13 to step A20 to check whether the mode has been switched from the computer mode to the other mode. If the mode is not switched to the other mode, Returning to step A11, the computer processing is continued, but when the computer mode is switched to another mode, the switching information (calculation procedure) for switching to the computer mode is printed out in the journal (step A21), and the number of times of non-registration switching is performed. Increment processing for adding "1" to the content of the counter 8-5 is performed (step A22). Then, the process returns to step A1.

On the other hand, when the mode switch MS is switched to the inspection mode at the end of the day's business, the inspection process is performed in step A3. In this case, the contents of the various totalizers 8-3 are the same as usual. Etc. are printed out on the inspection report, and then the contents of the registered switching number counter 8-4 and the non-registered switching number counter 8-5 are printed out. FIG. 6 shows a print example of the inspection report in this state. As a result, it is possible to easily confirm how many times the switching to the computer mode was performed during registration and non-registration from the print contents of this inspection report.

As described above, in this embodiment, when the mode is switched to the computer mode during the registration before the registration of one transaction is completed, the contents of the subtotal register 8-1 are stored in the calculation result memory 8-2. Then, calculations such as discounts and discounts can be performed on this subtotal amount. Further, when the computer mode is switched to during the registration, normal arithmetic operations and the like can be performed. Under this computer mode, opening of the drawer is prohibited, which is useful for preventing fraud of the operator. Then, when the computer mode is switched to another mode, the value of the registered switching count counter 8-4 or the non-registered switching count counter 8-5 that counts the switching count is updated, and the switching to the computer mode is performed. The information is printed out in the journal. Here, even if you switch to the computer mode during the registration of one transaction, the switching information is printed out after the registration of one transaction is completed, so the switching information is printed together with the registered contents during one transaction. It will not be done.
Further, the contents of the switching number counter during registration 8-4 and the switching number counter during non-registration 8-5 are printed out in an inspection report when the contents of the various totalizers 8-3 are inspected. Therefore, the number of times of switching to the computer mode and what kind of calculation has been performed can be left as the switching history information of the computer mode, which is useful for preventing fraud of the operator.

In the above-described embodiment, the contents of the registered switching number counter 8-4 and the non-registered switching number counter 8-5 are printed during inspection, but they may be printed during settlement. Alternatively, a switching number counter during registration 8-4 and a switching number counter during non-registration 8-5 may be provided for each person in charge, and the number of switching times for each person in charge may be counted and printed.

[0021]

According to the present invention, it is possible to switch to a computer mode in which a calculation process different from the registration process for registering sales data is performed, and the number of switching times indicating that the computer mode has been switched is counted. Since the information is output as described above, it is possible to effectively prevent the operator from fraudulently appearing as if performing a registration operation. In addition, when switching to the computer mode, switching to the computer mode is allowed only when the switching conditions preset for each person in charge are satisfied, which is more effective in preventing fraud. is there.
