Definitions

  • the present invention relates to an electronic cash register system having a plurality of cash registers which operate in systematic fashion.
  • An electronic cash register system having a plurality of electronic cash registers includes a parent electronic cash register, which is provided with a memory serving as a master file, a child electronic cash register, and a line, which communicates the parent cash register and the child cash register with each other in such a manner as to allow mutual communication therebetween.
  • This arrangement is often referred to as an in-line system.
  • the foregoing system typically operates based on the following steps.
  • the foregoing system has a shortcoming that when a failure causes the parent cash register to be inoperative, the overall in-line system must be inoperative, because the master file for storing the transaction data is provided only in the parent cash register. While the parent cash register is inoperative, the child cash register has to be operated as an individual device. If, therefore, the in-line system is provided with a plurality of child cash registers, it is impossible to draw the transaction data from all the child cash registers.
  • an electronic cash register system including: a parent electronic cash register provided with a first control device and a first memory for registering a transaction data inputted thereto; a quasi-parent electronic cash register provided with a second control device and a second memorv for registering a transaction data inputted thereto; a child electronic cash register provided with a third control device for registering a transaction data inputted thereto; and a line for communicating the registers to one another.
  • the first, second and third control devices accomplish a mutual communication between the registers through the line and controlling the registers so as to store the data registered by the parent, quasi-parent and child registers into the first and second memories respectively when the parent register operates normally, store the data registered by the quasi-­parent and child registers into the second memory when the parent register becomes inoperative, and transfer the data stored in the second memory to the first memory after the parent register is recovered to operate normally.
  • the parent register is provided with the first memory while the quasi-parent memory is provided with the second memory.
  • These first and second memories store the same content when these parent and quasi-parent registers operate normally in the in line operation of the svstem.
  • the second and third control devices of the quasi-parent and child registers notice this inoperative condition of the parent register by the mutual communication with the first control device of the parent register. Then, the second and third control devices control the quasi-­parent and child devices such that the second memory stores the transaction data inputted to the quasi-­parent and child registers so as to continue the in-­line operation of the system.
  • the first control device instructs to the second control device such that the the quasi-parent register transfers the data content stored in the second memory to the first memory. Then, the first, second and third control devices control the registers so as to resume the normal in-line operation of the system.
  • the system of the present invention makes it possible to make the quasi-parent register acting as an alternative of the parent register when some cause brings the parent register into the inoperative condition, and thus the system can keep operating by the cooperation of the remaining quasi-parent and child registers even if the parent register becomes inoperative.
  • Fig. 1 is a block diagram showing the overall in-line system according to an embodiment of the invention.
  • the in-line system includes a parent electronic cash register 11, a quasi-parent electronic cash register 12, a child electronic cash register 13, and a line 14 consisting of a cable. Those registers 11, 12 and 13 are connected through the line 14 for communicating them with one another.
  • the parent cash register 11 and the quasi-­parent cash register 12 respectively have master files 15 and 16.
  • Fig. 2 exemplarily illustrates how the in-line system shown in Fig. 1 operates normally. The operation will be carried out as follows.
  • a user registers the new transaction data, that is, performs the look-up operation at the child cash register 13.
  • the child cash register 13 sends out a request message 17 about the transaction data to the parent cash register 11 through the line 14.
  • the parent cash register 11 serves to draw the corresponding transaction data from the master file 15 and then transfer it to the child cash register 13 as indicated by an arrow 18.
  • the parent cash register 11 sends out a check message 19 for checking the presence or absence of the transaction data to the quasi-parent cash register 12.
  • This check message 19 is used for making sure if the master file 15 of the parent cash register 11 has the same store content as the master file 16 of the quasi-­parent cash register 12.
  • the quasi-parent cash register 12 serves to send out a response 20 indicating the presence or absence of the corresponding transaction data to the parent cash register 11. If the quasi-parent 12 does not have the corresponding transaction data, that is, it sends out the response indicating that it does not operate normally, the parent cash register 11 displays the error condition on a display 21 or prints it on paper so as to allow the user to see it.
  • the child cash register 13 serves to perform additional registration for, that is, update the transaction data received from the parent cash register 11 and then temporarily balance the book.
  • the parent cash register 11 serves to update the corresponding transaction data in the master file 15 of the parent cash register 11. At the same time, the parent cash register 11 serves to transfer the transaction data to the quasi-parent cash register 12.
  • the quasi-parent cash register 12 serves to update the corresponding transaction data.
  • the parent cash register 11 and the quasi-parent cash register 12 are effective as the child cash register and can perform those steps (A) to (F) as the child cash register. In this operation as the child cash register, these registers 11 and 12 allow the transaction data to be directly transferred to each of the master files 15 and 16 without transferring the transaction data through the line 14.
  • the parent cash register 11, the quasi-parent cash register 12, and the child cash register 13 respectively include input means 22, 23, 24 and processing circuits 25, 26, 27 realized by microcomputers, for example. These input means are used for registering the transaction data and performing the look-up operation.
  • the parent cash register 11 includes the display 21 as mentioned above.
  • the quasi-parent cash register 12 and the child cash register 13 respectively provide displays 28 and 29.
  • Figs. 3, 4 and 5 are flowcharts illustrating how the processing circuit 27 included in the child cash register 13 operates.
  • the operation of the child cash register 13 starts at a step al, then the transaction data is registered at a step a2. Then, at a step a3, the child cash register 13 sends out the request message about the transaction data to the parent cash register 11 through the line 14.
  • the child cash register 13 receives the transaction data stored in the master file 15 of the parent cash register 11. Proceeding to a step a5, the new data is registered on the input means 24.
  • the child cash register 13 temporarily balances the book. Then, at a step a7, the child cash register 13 transfers the resulting transaction data to the parent cash register 11 through the line 14. Then, this sequential operation of the child cash register 13 is finished at a step a8.
  • Fig. 4 is a flowchart illustrating how the child cash register 13 operates when the parent cash register 11 becomes inoperative.
  • the flow starts at a step C1 when the child cash register is operating normally as in Fig. 3.
  • the child cash register 13 judges if it receives a declaration message from the quasi-parent cash register 12 for acting as an alternative of the parent cash register 11. If the child cash register 13 receives the declaration message, at a step c3, it sets to communicate with the quasi-parent cash register 12 in place of the parent cash register 11 and this setting operation of the child cash register 13 is finished at a step c4.
  • Fig. 5 is a flowchart illustrating how the child cash register 13 operates after the parent cash register 11 is recovered.
  • the child cash register 13 is communicating with the quasi-parent cash register 12.
  • the child cash register 13 judges that the parent cash register 11 is recovered to operate normally at a step d2
  • the child cash register 13 is reset to communicate with the parent cash register 11 at a step d3.
  • this resetting operation is finished.
  • Fig. 6 is a flowchart illustrating how the processing circuit 25 provided in the parent cash register 11 operates.
  • the flow starts at a step b1 when the parent cash register is operating normally.
  • the parent cash register 11 receives the request message about the transaction data from the child cash register 13 or the quasi-parent cash register 12. Proceeding to a step b3, the parent cash register 11 serves to retrieve the master file 15 and then, at a step b4, transfer the corresponding transaction data retrieved from the master file 15 to the child cash register 13.
  • the parent cash register 11 sends out a check message for checking the presense or absense of the transaction data to the quasi-parent cash register 12.
  • the register 11 judges if it receives a response indicating the presence or absence of the corresponding transaction data from the quasi-parent cash register 12. If no transaction data is found, that is, an error takes place in the quasi-parent cash register 12, at a step b7, the display 21 indicates the error condition. If it is judged that there takes place no error, this sequential operation of the processing circuit 25 is finished at a step b8.
  • Fig. 7 is a flowchart illustrating how the processing circuit 25 provided in the parent cash register 11 operates when it receives the response indicating the presence of the corresponding transaction data.
  • the flow starts at a step el when the parent cash register 11 is operating normally.
  • the parent cash register 11 receives the transaction data inputted and temporarily balanced in the child cash register 13 or the quasi-parent cash register 12.
  • the register 11 serves to update the corresponding data in the master file 15.
  • the parent cash register 11 can execute the other process.
  • the register 11 serves to send out the corresponding transaction data to the quasi-­parent cash register 12 in such a manner as to allow the content stored in the master file 16 to be equal to that stored in the master file 15. Then, this sequential operation of the processing circuit 25 is finished at a step e5.
  • Fig. 8 is a flowchart illustrating how the processing circuit 25 of the parent cash register 11 operates when the register 11 is recovered to operate normally after a failure caused it to stop.
  • the flow starts at a step f1 when the operation of the parent cash register 11 is inoperative by the failure. If it is judged that the parent cash register 11 is recovered to operate normally at a step f2, then at a step f3, the parent cash register 11 receives and collects the transaction data from the master file 16 provided in the quasi-parent cash register 12 and stores it in the master file 15. At a step f4, the parent cash register 11 sends out the declaration data for acting as a parent cash register to the child cash register 13. Then, at a step f5, this sequential operation of the processing circuit 25 is finished.
  • Fig. 9 is a flowchart illustrating how the processing circuit 26 provided in the quasi-parent cash register 12 operates.
  • the flow starts at a step g1 when the registers 11 and 12 are communicating with each other.
  • the quasi-parent cash register 12 receives a check message indicating the presence or absence of the transaction data from the parent cash register 11.
  • the register 12 sends out a response.
  • the register 12 receives the transaction data from the parent cash register 11 in normal operation and updates the master file 16 at a step g5. Then this operation of the registers 11 and 12 is finished at a step g6.
  • Fig. 10 is a flowchart illustrating how the quasi-­parent cash register 12 operates as an alternative of the parent cash register 11 when the parent cash register 11 is made inoperative.
  • the flow starts at a step h1 when the parent cash register 11 is inoperative.
  • a step h2 it is judged if an external operation to make the quasi-parent cash register 12 act as an alternative of the parent cash register 11 is performed via the input means 23 or not when the register 11 is inoperative. If the judgement is YES, at a step h3, the quasi-parent cash register 12 sends out the declaration data for acting as a parent cash register to the child cash register 13 through the line 14.
  • the child cash register 13 can communicate with the quasi-parent cash register 12 in the similar manner that it communicates with the parent cash register 11.
  • the quasi-parent cash register 12 instructs the child cash register 13 to prohibit the communication with the parent cash register 11. Then, this alternative setting operation is finished at a step h5.
  • Fig. 11 is a flowchart illustrating how the quasi-­parent cash register 12 operates when the parent cash register 11 is recovered to operate normally.
  • the flow starts at a step j1 when the quasi-parent cash register 12 is operating as the alternative of the parent cash register 11.
  • the quasi-parent cash register 12 receives a parent-cash-register-recovering declaration from the parent cash register 11.
  • the register 12 serves to transfer the transaction data stored in the master file 16 to the master file 15 of the parent cash register 11.
  • the parent cash register 11 accomplishes the following operatin based on the content stored in the master file 15.
  • the registers 12 and 13 are reset to communicate with the parent cash register 11. Then, this recovering operation is finished at a step j5.
  • the quasi-parent cash register 12 serves to transfer the latest transaction data stored in the master file 16 to the master file 15 of the parent cash register 11 in such a manner as to allow the register 11 to collect the transaction data.
  • This operation is carried out at the step f3 as shown in Fig. 8.
  • the operations illustrated in Figs. 3, 8 and 10 are main process and the operations illustrated in Figs. 4, 5, 6, 7, 9 and 11 are sub process.
  • the quasi-parent cash register 12 can acts as the alternative of the parent cash register 11. It results in being able to prevent the overall in-line system from being inoperative until the parent cash register 11 is recovered.
  • the parent cash register 11 can draw the latest transaction data from the master file 16 of the quasi-parent cash register 12 to the master file 15 and collect all the data in the master file 15. This operation makes it possible to precisely return the transaction data involved in the overall in-line system to the parent cash register 11.
  • the in-line system may be provided with more child cash registers 13 or employ the arrangement wherein the line 14 merely has the parent cash register 11 and the quasi-parent cash register 12 connected thereon.
