FIG. 5 is a flowchart schematically showing the flow of the return process. First, in step S1, the process waits until any one of various keys provided on the keyboard 4 is pressed.

One of the keys is pressed (step S1).
If the pressed key is the designated cancel key 4d (Y in step S2), it is determined in step S3 whether the control key 5 is in the MGR mode. If the control key 5 is not in the MGR mode (N in step S3), the designated cancel key 4d is a key that needs to be pressed in the MGR mode that exerts the MGR compulsory function.
The process based on this function is not executed, and the process proceeds to step S4. In step S4, it is determined whether the control key 5 is in the registration mode. These steps S3 to
S4 is repeated until the control key 5 is switched to the MGR mode (Y in step S3) or any key is pressed in the registration mode (Y in step S5).

If any key is pressed (Y in step S5), it is determined in step S6 whether the pressed key is the MGR forced release key 4c. If the pressed key is the MGR forced release key 4c (Y in step S6), it recognizes that a temporary release request to prohibit execution of an operator other than the predetermined operator has been made, Proceed to step S7. Here, the function of the cancellation request recognition means is executed.

In step S7, the MGR compulsory release code obtained by reading the MGR compulsory release barcode BC by the barcode scanner 10 and the cashier No. Wait until there is acquisition. MGR forced release code and cashier No. Is acquired (Y in step S7), it is determined in step S8 whether the acquired code is the same as the registered MGR compulsory cancellation code stored in the RAM 15. The acquired MGR forced release code is registered M
If it is the same as the GR compulsory release code (step S1
0, Y), the cashier No. which was identified as an appropriate operator and was acquired at the same time. The operator is identified by the "Casher No." Is stored in the print buffer of the RAM 15. By these steps S7 to S8, the function of the operator identifying means is executed.

In the following step S9, the printer 6 prints the "MGR forced release message", the "time" of the process, and the acquired "casher No." on the journal.
Here, a part of the function of the operation history recording unit is executed.

In step S10, even if the designated cancel key 4d which needs to be pressed in the MGR mode for exerting the MGR forcible function is pressed in the registration mode, execution by an operator other than the predetermined operator is performed. Is temporarily released, the return process corresponding to the return after the end of the closing process is executed, and the content is printed on the journal. Here, the function of the cancellation permission means is executed. Also, a part of the function of the operation history recording unit is executed.

If it is determined in step S2 that the pressed key is not the designated cancel key 4d (N in step S2), a process based on the function of the pressed key is executed in step S11.

In step S3, when the control key 5 is in the MGR mode (Y in step S3), the MGR compulsion function is properly performed, and
In step S12, a return process corresponding to the return after the end of the closing process is executed based on the designated cancel key 4d.

If it is determined in step S4 that the mode is not the MGR mode or the registration mode (N in step S4), and if the key pressed in step S6 is not the MGR forced release key 4c (N in step S6), the MGR forced release acquired in step S8 is performed. If the code is not the same as the registered MGR compulsory release code (N in step S8), in step S13,
Perform error handling.

In step S10, when the execution of the return process corresponding to the return after the closing process is completed by temporarily canceling the prohibition of the execution of the operator other than the predetermined operator, Again the designation cancellation key 4d is M
It becomes necessary to depress in the MGR mode that exhibits the GR compulsory function.

Here, a description will be given of a return process in a case where it is not possible to switch to the MGR mode when the customer is requested to return the purchased product after pressing the deposit / current total key 4b. First, the cashier presses the designated cancel key 4d, but the designated cancel key 4d is pressed in the MGR mode in which the MGR compulsion function, which is a function of giving special authority only to a predetermined operator such as a store manager or a manager, is performed. Since it is necessary to do so, it is not possible to immediately execute the return processing based on the pressing of the designated cancel key 4d. However, subsequently, the MGR compulsory release key 4c is pressed, and the MGR compulsory release code of the MGR compulsory release bar code BC on the ID card of the operator and the cashier No. Is read by the barcode scanner 10 to identify the operator and identify that the operator is a proper operator. Therefore, even if the operator cannot switch to the MGR mode, the operator other than the predetermined operator Is temporarily released so that the return process can be executed.

In this state, the bar code scanner 10 reads the product code of the corresponding product, so that the product name, unit price,
The department code is acquired, the cash register is executed in the sales file, and the content is
Recorded above. Here, FIG. 6 is a plan view showing an example of the printed journal paper P. As shown in FIG.
On the journal paper P, the “MGR forced release message”, the processed “time”, the information “Casher No.” for identifying the processed cashier, and the pressing of the designation cancel key 4d as in the past. The content of the return process is printed.

Therefore, even if the mode cannot be switched to the MGR mode, the cashier executes the return processing, and the cashier that has executed the return processing on the journal paper P on which the content is printed is identified. By clarifying the time of the process, the operator, and the content of the process, it is possible to prevent fraud such as wearing the amount of the cancellation.

In this embodiment, the merchandise sales registration data processing device is applied to the POS terminal 1,
