  • the number of kinds of sales data in the PLU file of controller 13 is larger than that of kinds of sales data in the PLU file in hand scanner 11.
  • Sales data which is not in PLU file 11-29 of hand scanner 11 can be obtained by calculation based on sales data in the PLU file of hand scanner 11. Since the kinds of the sales data in the PLU file of hand scanner 11 may be small in number, the memory capacity of hand scanner 11 can be saved.
  • the registration pro­cess by PLU codes may be performed by the normal key operation procedure through keyboard 11-2 on hand scanner 11 with the hand scanner placed on the controller, or by scanning the labels of commodities with the hand scanner in hand.
  • Hand scanner 11 performs operations shown in the flowchart of Fig. 7.
  • Hand scanner 11 is placed in the wait state first until the scanning or key operation is performed while checking as to whether the label of a product is scanned (step A1) or keyboard 11-2 is operated (step A2).
  • CPU 11-11 When a key is pressed in this state, CPU 11-11 responds to the key operation to carry out the key entry process (step A3) and then decides whether the operated key is finalizing key FK or not in step A4. When the finalizing key FK is operated, the finalize flag is set on (step A5). However, if a PLU key (not shown) is pressed during the registration process, then the control operation proceeds to step A6 without setting the finalize flag on.
  • step A6 Since in this case the off state of the finalize flag is detected in step A6, the normal registration operation, such as the subtotal calculating operation, is carried out and the results of the opera­tion are stored in RAM 11-17 in step A7, and then the sold number in PLU file 11-31 corresponding to the entered PLU code is updated in step A8. In this case, if he need, the sold number of each department or article number linked with the PLU codes is also updated. And, the operation returns to step A1 so that the above process is repeated each time a PLU code is entered through the keyboard. Consequently, the sold number of each commodity in PLU file 11-31 is updated.
  • step A9 PLU file 11-31 is retrieved on the basis of the read PLU code, the unit price corresponding to the PLU code is read from the file. Subsequently the normal registration operation such as the subtotal calculation is carried out and the result of the operation is stored in RAM 11-17 in step A10. The sold number corresponding to the PLU code in PLU file 11-31 is updated in step A11. The operation then returns to step A1 to repeat the above operation each time the scanning is performed. As a result, the sold number for each commodity in PLU file 11-31 is updated.
  • step A13 When the registration process of a sale is completed, finalizing key FK is pressed. This is detected in step and then the process proceeds through steps A5 and A6 to step A12 in which the finalize opera­tion, for example, the calculation of change is carried out. Data to be transmitted to controller 13 is pre­pared and stored in buffer 11-17-1 in step A13.
  • CPU 11-11 monitors the charging of secondary bat­tery 11-20.
  • CPU 11-11 decides that the hand scanner has been placed on controller 13.
  • the CPU transmits the data stored in buffer 11-17-1 through transmitter 11-18 to the controller 13 in step A14, clears all the sold number data and the subtotal data stored in subtotal memory in PLU file 11-31, and clears data stored in buffer 11-17-1 in step A15, and clears the finalize flag in step A16.
  • Fig. 8 shows the format of transmission data.
  • the transmission data comprises a start code, a drawer open command which is set when change needs to be given, a PLU code, the subtotal, a code for each sale, a receipt printing command which is set when an operator presses a receipt issue key in response to the request of a customer to issue a receipt, and an end code.
  • the PLU code may involve any one of PLU codes in which the sold number in PLU file 11-31 is one or more. Namely, the PLU code in which the sold number is zero is excluded. In the case of a sale of a plurality of products the number of the PLU code Corresponding to the sold number is set.
  • sold number in the PLU file 11-31 Since all the sold numbers in PLU file 11-31 are cleared each time the registration of a sale of a sale is completed, that the sold number in the PLU file 11-31 is one or more represents the record of the pre­sent sale. The sales data on the department and article number is also transmitted in the same manner.
  • controller 13 In response to the data thus transmitted from hand scanner 11, controller 13 performs the process according to the flowchart of Fig. 9.
  • hand scanner 11 When hand scanner 11 is placed on controller 13 (in this case erroneous transmission of data decreases and data transmission speed improves as compared with the case where they are separated from each other), the transmission of data from hand scanner 11 is detected in step B1 and then a check is made as to whether the drawer open command is received or not in step B2.
  • a drive signal is applied to drawer body 12 in step B3 so as to open the drawer and then the process returns to step B1.
  • CPU 13-11 retrieves the PLU file 13-20 and performs an operation for updating the sold number, the amount of sales in PLU file 13-20 and the total stock in accordance with the sold number in step B4. Subsequently the result of the operation is transferred to PLU file 13-20 to update the sold number, the amount of sales and the total stock corresponding to the PLU code in step B5.
