It has a numeric key 1a for operating and a function key 1b for instructing various processing contents.

A memory M3 for each PLU is formed in the RAM 64. As shown in FIG. 7, the memory M3 for each PLU has areas for storing, for each product, a bar code number corresponding to each product, a unit price, a total sales quantity, a total sales price, and a stock quantity. . The bar code number and unit price are preset, and the total sales quantity, the total sales price, and the stock quantity are transmitted from each hand scanner A, or the bar code number self-entered by the key input unit C1, It is updated under the control of the CPU 40 based on the number of sales. Then, by operating a predetermined key of the key input unit C1, the contents of the memory M3 for each PLU is saved in the floppy disk 65.

After the settlement processing, the CPU 61 sends a PL to each hand scanner A regarding a product with a large number of sales.
The U code and unit price are transmitted via the repeater B.

Next, the operation of each hand scanner A will be described. The CPU 15 of each hand scanner A first inputs the input data from the reading head unit A1 or the key input unit A2,
That is, the presence / absence of self-input data is determined (step S1 in FIG. 8). As a result, if there is self-input data and it is a receipt request command corresponding to the receipt request key 2c, a charging current flows to the secondary battery 2B. It is determined whether or not it is connected to the repeater B (steps S2 and 3). If connected, the power to the optical transmitter 17 is turned on, and the repeater B issues a receipt. Therefore, the contents of one transaction memory M2 together with the receipt request command and the machine No. In step S4, the optical transmitter 17 is turned off (step S4), and the process returns to step S1. On the other hand, if not connected, the power to the wireless transmission unit 19 is turned on, and the relay device B
In order to issue a receipt with, the contents of one transaction memory M2 together with the receipt request command and the machine number are transmitted by the wireless transmission unit 19 which is powered on, and after the transmission is completed, the power to the wireless transmission unit 19 is switched off ( The process returns to steps S3 and 5) and step S1.

When the self-input data is a closing command, the total sales amount of one transaction is calculated based on the unit price and the number in one transaction memory M2 and displayed on the display unit A3 to display the contents of one transaction memory M2. Clear (steps S6 and S7) and return to step S1.

When the self-input data is the bar code number and the sales quantity, it is stored in one transaction memory M2, and if the bar code number related to the input exists in the PLU memory M1, the PLU memory M1. The total number of sales is updated for the corresponding products of (steps S8, 9, 1
0, 11) and returns to step S1. on the other hand. If the barcode number for input does not exist in the memory M1 for each PLU, the main unit register C is sent via the wireless transmission unit 19 and the repeater B.
In order to inquire about the unit price, the power to the wireless transmission unit 19 is turned on, the bar code number for the input is transmitted to the repeater B together with the machine number, and then the power to the wireless transmission unit 19 is turned off (step (S12, 13), and returns to step S1.

When data other than the above is input, processing according to the input data is performed (step S14),
Return to step S1.

When it is determined in step S1 that there is no self-input data from the read head unit A1 or the key input unit A2, the process proceeds to step S15, and it is determined whether there is transmission data from the repeater B. As a result, when there is transmission data and it is connected to the repeater B, predetermined power is transmitted in response to the transmission data via the optical transmission unit 17, so the power supply to the optical transmission unit 17 is turned on. It is turned on (steps S16 and 17). On the other hand, when there is transmission data and it is not connected to the repeater B, since the predetermined data is transmitted in response to the transmission data via the wireless transmission unit 19, the optical transmission unit 17 is powered on. Yes (step S1
8). Then, it is determined whether or not the transmission data is the settlement start command transmitted from the headquarters register C. If the transmission data is the settlement start command, in response to the settlement start command, all the products in the PLU-specific memory M1 are sent. It is determined whether or not the bar code number and the sales quantity have been transmitted as the settlement data (steps S19 and S26). as a result,
When the transmission is not completed, the buzzer 22 is sounded in order to connect with the repeater B and prompt the transmission from the optical transmitter 17 having a high transmission speed (step S21). And
The presence or absence of the connection with the repeater B is determined, and when the connection is established, the optical transmitter 17 is turned on if the power is currently off, and through the optical transmitter 17, the machine No. and P
The bar code number and the total sales quantity of each product in the LU-based memory M1 are sequentially transmitted to the repeater B as adjustment data (steps S22, 23, 24). On the other hand, when the wireless transmitter 19 is not connected, the wireless transmitter 19 is turned on if the power is currently off, and the machine N is connected via the wireless transmitter 19.
At the same time, the bar code number and the total sales quantity of each product in the memory M1 for each PLU are sequentially transmitted to the repeater B as the adjustment data (steps S25 and S24). And PL
It is determined whether or not the bar code numbers and the total sales quantity of all products in the U-based memory M1 have been transmitted (step S2).
6). As a result, when the transmission has not been completed, the process returns to step S22, and the same processing is repeated until the transmission is completed. When the transmission is completed, a transmission completion signal is transmitted to the repeater B to clear the total sales quantity of all the products in the memory M1 for each PLU, and to the optical transmission unit 17 or the wireless transmission unit 19 in the power-on state. Turn off the power (steps S27, 28),
Return to step S1.

By the processing of steps S19 to S26, a certain hand scanner A is connected to the repeater B, and the optical transmitter 17
During high-speed transmission, the other hand scanner A keeps the radio transmission unit 1 having a relatively low transmission speed during that period.
In the range of limited resources, by performing transmission at 9 and connecting and performing high-speed transmission when the repeater B becomes available,
As a whole, it will be possible to perform high-speed transmission as much as possible.

When it is determined in step S19 that there is no settlement start command, the process proceeds to step S29,
It is determined whether the transmitted data is the unit price as the response data to the inquiry in step S12. As a result, when it is the unit price, it corresponds to the bar code number and the sales quantity of the product stored in the one transaction memory M2 in step S9 and not preset in the memory M1 for each PLU,
Store the unit price, the barcode number for the product,
The number of sold products is transmitted to the repeater B via the optical transmitter 17 or the wireless transmitter 19 which is currently powered on (step S30). Then, the power to the optical transmitter 17 or the wireless transmitter 19 which is currently on is turned off (step S3).
1) and returns to step S1. When the transmission data is not the unit price, a predetermined process corresponding to the transmission data is performed (step S32), and the process returns to step S1.

In this way, the optical transmitter 17 and the wireless transmitter 1
The power supplies to 9 are turned on only when using them to transmit, thus saving power consumption.

Next, the operation of the repeater B will be described. The CPU 51 of the repeater B first determines whether or not there is transmission data from the hand scanner A (step S51 in FIG. 9). As a result, if there is transmission data from the hand scanner A, it is judged whether or not the transmission data is a receipt request command, and if it is a receipt request command, the registration data for one transaction that is transmitted subsequently. Is stored in the print buffer Bu2 (steps S52 and S53). If the printing flag F is not set and printing is not in progress, the printing flag F is set and one transaction is printed from the beginning in the print buffer Bu2 as a receipt (steps S54 and S55). . Next, when the content of one transaction from one hand scanner A has been printed, the receipt paper is cut, a receipt is issued, the printing flag F is reset, and the printed content is cleared ( Step S56,
57). Then, if data remains in the print buffer Bu2 (step S58), while one transaction data from one hand scanner A is being received and printed, the transaction data from another hand scanner A is received. Since it means that the registration data of (1) has been received and the receipt printing for that portion has been reserved, the process returns to step S55 and the receipt printing for that portion is performed.
On the other hand, there is no data remaining in the print buffer Bu2,
When all the data have been received and printed, the process returns to step S1.

When it is determined in step S52 that the data from the hand scanner A is not the receipt request command, the unit price inquiry data and the settlement data which are transmission data other than the receipt request command and the registration data for one transaction. The transmission completion signal is stored in the transfer buffer Bu1, is transferred to the head office register C via the transmission control unit 53 (steps S59 and 60), and the process returns to step S1.

If it is determined in step S51 that there is no transmission data from the hand scanner A, step S51.
Proceeding to 61, it is determined whether or not there is transmission data from the head office register C. As a result, when there is transmission data from the central register C, the data, that is, the unit price, the settlement start command, and the preset data to the memory M1 for each PLU are transferred to the transfer buffer corresponding to the machine number transmitted at the same time. It is stored in Bu1 and it is determined whether or not there is the connected hand scanner A (steps S62 and S63). As a result, when there is a connected hand scanner A, if there is transmission data for it, the optical transmitter 55 is turned on, and for the connected hand scanner A, the optical transmitter 5 is connected.
If there is data to be transmitted to the other hand scanner A, the wireless transmission unit 57 is turned on and the data is transferred to the other hand scanner A via the wireless transmission unit 57 (step S64). On the other hand, when there is no hand scanner A connected, the wireless transmission unit 57 is turned on to turn on the wireless transmission unit 57.
The transmission data is transferred to each hand scanner A corresponding to the machine No. via (step S65).

Then, the power to the optical transmitter 55 or the wireless transmitter 57 during the power-on is turned off (step S6).
6) and returns to step S1. In this way, the power supply to the optical transmission unit 55 and the wireless transmission unit 57 is turned on / off as necessary, so that the relay B also saves power consumption.

Next, the operation of the headquarters register C will be described.
The CPU 61 of the head office register C first transmits a settlement start command to each hand scanner A if it is in the settlement mode (steps S101 and 102 in FIG. 10). Then, when data is transmitted from the hand scanner A in response to the settlement start command, it is determined whether or not the data is a transmission completion signal (step S10).
3, 104). As a result, when the transmission data is not the transmission completion signal, it means that it is the adjustment data for the PLU-specific memory M1 of the hand scanner A, and therefore the content of the self-PLU-specific memory M3 is updated based on the adjustment data. (Step S105). Next, it is judged whether or not the transmission completion signals have been received from all the hand scanners A,
When it is received from all, it means that the sales data collection from each hand scanner A is completed.
The contents of the LU memory M3 are settled and printed (step S1).
07). Then, in the memory M3 for each PLU, among the items whose total sales quantity has been changed, the top 100 products with the largest total sales quantity are searched, and the bar code number of the searched product,
The unit price is transmitted as preset data to all hand scanners A (steps S108 and 109), and the process returns to step S101.

As a result of this transmission, as described above, the unit price for 100 types of products that are selling well is preset in the memory M1 for each PLU of each hand scanner A.

Therefore, the following advantages occur. That is, the memory capacity of the RAM 21 in which the memory M1 for each PLU of each hand scanner A is formed can be reduced by limiting the preset to 100 kinds of products that sell well among many products. In addition, since the products that sell well are selectively preset, the number of unit price inquiries to the headquarters register C can be reduced as much as possible even if not all products are preset. Therefore, even if a unit price inquiry is made by wireless transmission having a relatively low transmission speed, it is possible to avoid a decrease in registration processing speed as much as possible. Further, even if the transmission speed is slightly reduced by the wireless transmission, the freedom of movement is guaranteed by the wireless transmission and it is not necessary to go to the relay device B, so that the work efficiency is increased as a whole.

If it is determined in step S106 that the hand scanner A has not received the transmission completion signal, the process returns to step S103 to continue data collection.
Further, when it is determined in step S103 that there is no transmission data, and when it is determined in step S104 that the transmission data is not the transmission completion signal, both of them are performed in step S106.
Proceed to.

In the registration mode, the presence or absence of data input is determined (steps S101, 110, 111). As a result, if there is a data input, it is determined whether or not it is the inquiry data from the hand scanner A that is relayed and transmitted by the relay device B (step S112). , The unit price of the product related to the inquiry is transmitted to the hand scanner A as the inquiry source (step S11).
3). Then, in accordance with the transmission of the unit price, it is determined whether or not the sales quantity of the product has been transmitted from the hand scanner A of the transmission destination (step S114). The total sales quantity and the stock quantity of the corresponding products in the memory M3 are updated (step S11).
5) and returns to step S101. On the other hand, when the sales quantity has not been transmitted, the process returns to step S113 and the unit price transmission is repeated.

When it is determined in step S112 that the input data is not inquiry data, it is determined whether the input data is sales data from its own key input section C1 (step S116). , Step S11
Proceed to No. 7, and based on the sales data concerned, own PLU
Registration processing such as updating the total sales quantity and the stock quantity in the separate memory M3 and printing a receipt is performed. If the sales data is not the self-input sales data, a process according to the input data is performed (step S118), and the process returns to step S101.

In the modes other than the payment mode and the registration mode, the process according to the mode is performed (step S1).
19).

As described above, although the transmission speed is relatively slow, the wireless transmission that can be transmitted separately and the optical transmission that can achieve high speed at the time of connection can be selectively used according to the situation.
Overall, work efficiency can be improved.

The present invention is not limited to the above-described embodiment, and for example, optical transmission or radio transmission may be directly performed to the register C of the head office without passing through the repeater B. Further, it can be applied to a data processing device other than the electronic register, such as a personal computer or an office computer.
