Description

TECHNICAL FIELD The present invention relates to a POS system.

[Prior Art] In a store such as a department store or a large-scale supermarket that has multiple accounting locations, a plurality of electronic cash registers and one store controller installed in each accounting location are used as transmission lines. In-line connection via the electronic cash register, and the product sales data such as the sales amount and sales points of the sales products registered in each electronic cash register are transmitted to the store controller via the transmission line, and the file is provided in the store controller. Generally, a POS (point-of-sale information management) system is used in the memory, for example, for each product code.

In addition, a buzzer is generally incorporated in the electronic cash register, and when a key operation error or a receipt or paper out error of a journal paper occurs, the buzzer sounds to notify an operator. The volume of the buzzer and the like are adjusted individually by electronic hardware such as volume.

[Problems to be Solved by the Invention] As described above, the conventional POS system is complicated because the operator has to adjust the buzzer sound of the electronic cash register for each register. If the buzzer sound is too loud, it makes the customer feel uncomfortable, and if the buzzer sound is too quiet, it cannot be heard by the operator. In addition, the buzzer sounds well during times when there are few customers, but it may not be heard even if it is a little loud when crowded. Therefore, it is necessary to adjust the buzzer sound as needed, which is a burden on the operator.

Therefore, the present invention aims to provide a POS system that can eliminate the need for adjusting the buzzer sound for each electronic cash register and reduce the burden on the operator.

[Means for Solving Problems] According to the present invention, as shown in FIG. 1, a plurality of electronic cash registers 2 having a buzzer 1 and product sales data generated from each electronic cash register 2 are totaled. In a POS system in which one store controller 4 having a file memory 3 for operating the in-line connection via a transmission line 5, each electronic cash register 2 sends a buzzer sound information to the store controller 4 when the power is turned on. Buzzer sound information requesting means 6 for requesting
By the buzzer sound information storage means 7 for storing the buzzer sound information returned from the store controller 4, and a buzzer sound control means for controlling the sound of the buzzer 1 based on the information stored by the buzzer sound information storage means 7 when an error occurs. 8 and 8.

[Operation] In a POS system that takes such a means, each electronic cash register stores the buzzer sound information transmitted from the store controller when the power is turned on, and based on this buzzer sound information, the electronic cash register The buzzer sound of is automatically controlled.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing a POS system, in which a plurality of electronic cash registers 11 and one store controller 12 are connected in a closed loop via a transmission line 13, and each electronic cash register 11 is connected. Are controlled by the store controller 12. In addition, the store controller 12 includes each electronic cash register 11
A large-capacity file memory 14 for connecting the product sales data registered in 1. for each product code is connected.

FIG. 3 is a block diagram showing a circuit configuration of the electronic cash register 11. In the figure, the CPU 21 has a built-in arithmetic circuit and the like, performs predetermined arithmetic processing based on various input data, and stores ROM 23 that stores fixed data such as programs via the bus line 22 and various input data and arithmetic processing data. And RAM 24 for storing variable data such as. A buzzer sound information memory 25 for storing the buzzer sound information transmitted from the store controller 12 is formed in the RAM 24.

Also, "register" to the CPU 21 via the bus line 22.
Control key input circuit 27 for inputting a signal from control key 26 for instructing CPU 21 to execute a business mode as an electronic cash register such as "settlement" and "setting", product code of sold product, sales amount, sale A keyboard input circuit 29 for inputting a key signal from a keyboard 28 for inputting merchandise sales data such as points, and a display unit 30 for displaying the sales amount or the total amount of sales of the merchandise that has been keyed in are driven and controlled. Data transmission between the display control circuit 31, the printer / drawer control circuit 34 for driving and controlling the printer 32 for printing on receipts and journals and for opening the drawer 33, and the store controller 12 via the transmission path 13. A transmission interface 35 for controlling the device and a buzzer circuit 36 are connected.

FIG. 4 is a circuit diagram of the buzzer circuit 36. As shown in the figure, a decoder 42 for decoding the buzzer sound data is connected to an output port 41 that outputs the buzzer sound data provided from the CPU 21 via the bus line 22, and the output of this decoder 42 is It is connected to the buzzer 43 via the eight-divided series resistors r1 to r8.

Then, when the power is turned on, the CPU 21 executes the processing shown in FIG. 5 by the program of the ROM 23. That is,
After completion of predetermined initial processing such as clearing the RAM 24 and clearing the input / output port, the store controller 12 is queried for buzzer sound information. When the buzzer sound information is transmitted from the store controller 12 as a response to this inquiry, the buzzer sound information is received, and the received buzzer sound information is stored in the buzzer sound information memory 25 in the RAM 24. Here, the buzzer sound information is data instructing the volume of the buzzer 43, and is data that can be set and changed by the store controller 12. After that, the process shifts to the normal process.

As the normal process, when the product code of the product to be sold is input from the keyboard 28 in the "registration" mode, the product code inquiry is made to the store controller 12. Then, the store controller 12 searches the large-capacity file memory 14 and reads out the unit price, product name, department, etc. corresponding to the corresponding product code and transmits it as response data. Therefore, the CPU 21 receives the response data, displays the product name and unit price on the display 30, and causes the printer 32 to print the receipt and the journal. Further, the sales data such as the number of sales (normally 1), the amount of sales (unit price × the number of points), etc. are transmitted to the store controller 12 again. This sales data is accumulated in the large capacity file 14 under the control of the store controller 12, for example, for each product code.

In this normal processing, when the CPU 21 detects the occurrence of a key input error or a paper out error in the printer 32, it executes the error processing shown in FIG. That is, the buzzer sound information stored in the buzzer sound information memory 25 in the RAM 24 is read. Then, the read buzzer sound information is sent to the output port 41 in the buzzer circuit 26. Then, the buzzer sound information is output from the output port 41 and decoded by the decoder 42, and the current value to the buzzer 43 is determined by the decoder output based on this result, and the buzzer 43 sounds at the volume corresponding to this current value. To do. afterwards,
When the release of the error state is detected, the output of the buzzer sound information is stopped.

Further, when the CPU 21 receives a buzzer sound change command interrupt from the store controller 12 in the normal processing state,
Create a reception system for buzzer sound information. When the buzzer sound information is received, the contents of the buzzer sound information memory 25 are switched to the received buzzer sound information, and the process returns to the normal process.

As described above, in the present embodiment, when the power of each electronic cash register 11 is turned on, the buzzer sound transmitted from the store controller 12 to the buzzer sound information memory 25 formed in the RAM 24 of each electronic cash register 11 is transmitted. Information is stored. Then, when an error event occurs in the subsequent normal processing, the buzzer sounds at the volume determined by the error and error information stored in the memory 25.

Further, when the buzzer sound change command is given from the store controller 12 and the changed buzzer sound information is received, the contents of the buzzer sound information memory 25 are rewritten, and thereafter, the buzzer 43 at the volume corresponding to this change information is received. Sounds.

Therefore, according to the present embodiment, by setting the buzzer sound information corresponding to the desired buzzer sound volume on the side of the store controller 12, the collective buzzer sound volume is set only by turning on the power of each electronic cash register 11. . Also, when the installation environment of the electronic cash register 11 changes due to congestion or a quiet time, and the buzzer sound volume is no longer appropriate, the store controller 12 only sends a command to change the buzzer sound information. Then, the buzzer volume of each electronic cash register can be collectively changed to the volume suitable for the environment. Therefore, the operator of each electronic cash register does not need to appropriately adjust the volume according to the volume or the like, and the labor can be reduced and the workability can be improved.

The present invention is not limited to the above embodiment.
For example, in the above-mentioned embodiment, the case of applying to the POS system using the electronic cash register 11 with a built-in printer is shown, but the R / J (receipt / journal) printer is an electronic cash register POS system for external connection. Is applicable. In this case, the buzzer sound information stored in the buzzer sound information memory 25 of the RAM 24 of each electronic cash register 11 is transferred to the memory of the RAM of the R / J printer in response to the power-on of the R / J printer. As a result, it is possible to collectively adjust the buzzer sound inside the printer for a paper out error or the like in the R / J printer.

Further, in the above embodiment, the case where the buzzer volume information is set by adjusting the current value to the buzzer according to the buzzer sound information has been described.
The sound quality may be set by changing the frequency or cycle of the buzzer. In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide a POS system that can eliminate the need for adjusting the buzzer sound for each electronic cash register and reduce the burden on the operator.
