2. Description of the Related Art In a conventional POS system of this kind, a circuit for controlling on / off of a main power supply by turning on / off a remote power control signal (hereinafter abbreviated as RPC signal) is provided in each satellite machine, and a master is provided. R on the machine
There is already known a circuit in which a circuit for supplying a PC signal to each satellite device is provided so that the main power of each satellite device can be remotely turned on and off by a master device.

[0003] In general, a satellite machine is configured to execute so-called registration work, in which, when information on a product for sale is input from an input unit, product sales data is acquired based on the input information and registered in a storage unit. ing.

[0004] The master unit includes a setting operation for preliminarily setting data necessary for executing various operations in the storage unit of the master unit and each satellite unit, and a sales of goods registered in the storage unit of each satellite unit. The system is configured to selectively execute a so-called inspection operation in which data is totaled in a storage unit and a report is output.

In a conventional POS system having a power supply remote control function, when a setting operation or an inspection operation is selected in the master unit, the main power supply of each satellite unit is automatically forcibly turned on, and the selection is performed. The system was configured so that the main power supply forced on state was released when the operation was completed.

[0006]

Incidentally, the setting work performed by the master unit includes a process of setting necessary data in its own storage unit. During this process, the main power supply of each satellite unit is forcibly turned off. You do not need to turn it on. Also, in the inspection work, after collecting data from each satellite machine, it only needs to collect the collected data and output a report, so it is not necessary to forcibly turn on the main power supply of each satellite machine. .

However, in the conventional POS system having the power supply remote control function, the main power supply of each satellite machine is forcibly turned on unconditionally during the period when the setting work or the inspection work is selected in the master machine. Power was wasted. In addition, since each satellite machine is inoperable during the period when the main power is forcibly turned on by the master machine, if setting work or inspection work is performed while the store is open, each work will be completed until the work is completed. On satellite machines, registration had to be interrupted, resulting in poor processing efficiency.

Accordingly, the present invention provides a plurality of satellite devices having means for controlling the turning on and off of the main power supply in accordance with the on and off of the RPC signal, and a master device having means for supplying an RPC signal to each satellite device. Connected via a transmission line, the main power of each satellite can be forcibly turned on only when executing the process of operating each satellite during the work performed by the master, which wastes power. It is an object of the present invention to provide a merchandise sales data processing device capable of suppressing the occurrence of a problem and improving the processing efficiency of each satellite machine.

It is configured to print out.

On the other hand, the master control unit 32 has a command table 40 in which a command sequence of various processings related to a setting operation or an inspection operation is set, and the host device 14 activates a command string via the host communication control unit 41. When the command string is activated by a key operation of the keyboard 36, the processing shown in FIG. 4 is executed.

First, the pointer TP of the command table 40 is initialized to "1" (ST1). Next, the command set in the area of the command table 40 indicated by the pointer TP is read and analyzed (ST2).

Here, if the command is "90" (YES in ST4), it is a command for forcibly turning on the power of each satellite device 2, so that the RPC signal generation circuit 34 generates each satellite device. The RPC signal supplied to the power supply 12 is turned on (ST5). Thereafter, if the pointer TP is updated by +1 (ST9), the command set in the area of the command table 40 indicated by the pointer TP is read and analyzed (ST2).

When the command is "99", (S
T6: YES), the command cancels the forced power-on state of each satellite device 2, so that the RPC signal is turned off (ST7). Thereafter, if the pointer TP is updated by +1 (ST9), the command set in the area of the command table 40 indicated by the pointer TP is read and analyzed (ST2).

When the command is "FF", (S
Since this is a command indicating the end of the command sequence (YES in T3), this process ends.

On the other hand, if the command is “FF”, “9”
If the command is other than "0" or "99", various processes related to the setting task or the inspection task corresponding to the command are executed. This processing includes the transaction-based totalizer 3 of the master unit 11.

There are a process for making a request, a process for totalizing collected data, a process for printing out the totaled data on recording paper by the printer 39 and outputting a report, and the like, and a unique command is set for each process.

Here, the command generation means of the master unit 11 comprises a process (ST2) of sequentially reading out a command string set in the command table 40 by activating the command string.

Similarly, the command judging means analyzes the command read from the command table 40, and executes "9
If it is "0", it is judged as an operation command of each satellite machine,
If it is "99", the processing is determined to be a non-operation command (ST
4, 6).

Further, the RPC signal control means similarly turns on the RPC signal if the command is "90", and "9"
If "9", the process of turning off the RPC signal (ST5, 7)
It consists of.

In this embodiment having such a configuration,
As shown in FIG. 4 (a), the transaction totalizer 24 of each satellite machine 2 accumulates product sales data for each department code for classifying each product, and the product sales data for each time zone. It is assumed that a totalizer 24b for each time zone, a totalizer 24c for each customer layer for accumulating product sales data for each customer layer, and the like are formed. In addition to the section totalizer 37a, the time slot totalizer 37b, the customer layer totalizer 37c, and the like, the PLU (price, look,
Up) It is assumed that a PLU-based totalizer 37d for accumulating product sales data for each code is formed.

Thus, the merchandise sales data registered in the transaction-specific totalizer 24 of each satellite machine 12 and the product sales data registered in the transaction-specific totalizer 37 of the master machine 11 are classified by type (by division, by time zone). Considering a case where an inspection task is executed in which data is totalized for each customer group and each PLU and output as a report.

In this case, the master unit 11 first requests each satellite unit 12 to collect the data of the transaction-specific totalizer 24, and when the data collection is completed, reads and collects the data of the transaction-specific totalizer 37. And each satellite machine 12
Totalizer 24 for each transaction and totalizer 37 for each transaction of the master machine 11
Then, the data collected from the above are aggregated by type, and the aggregated data is output as a report by the printer 39.

In this processing, the period during which each satellite machine 12 is operated is a period from when a data collection request is made to when the collection is completed.

Therefore, in the command table 40, first, a command "90" for forcibly turning on the power of each satellite machine 12 is set in the area of the pointer TP = 1. A command “10” requesting the data collection of the satellite 24 is set in the area of the pointer TP = 2, and then a command “99” for releasing the power-on state of each satellite machine 12 is set to the pointer TP = 2.
3, the command "20" for reading and collecting data from the transaction-based totalizer 37 is set in the area of the pointer TP = 4, and then the collected totalizer data is classified by type. Is set to the pointer TP = 5, and the command “40” of the process of outputting the total data as a report is set to the pointer TP = 6.
, And finally a command “FF” indicating the end of the command sequence is set to the pointer TP = 7.

In the command table 40, a command sequence of various processes relating to an execution task is set as appropriate by downloading from the host device 14.

In this state, when a command string is activated by a request from the host device 14 or by a key operation of the keyboard 36, the commands set in the command table 40 are read out in the order of pointers, and are instructed by the commands. Are sequentially executed.

That is, first, the command “90” is read, the RPC signal generation circuit 34 is controlled, and the RPC signal supplied to each satellite device 12 is turned on. Thereby, in each satellite device 12, the RPC circuit 29 operates to forcibly turn on the main power supply of the power supply unit 28.

Next, the command "10" is read and the in-line communication control unit 42 is controlled, and each satellite device 12
First, a data collection request of the transaction-specific totalizer 24 is made through the transmission line 13. As a result, in each satellite machine 12, the data accumulated for each type is read by the transaction-specific totalizer 24, and the transmission line 13
Is transferred to the master device 11 through

Next, the command "99" is read and the RP
The C signal generation circuit 34 is controlled, and the RPC signal is turned off. As a result, in each satellite device 12, the RPC circuit 29 operates to release the main power supply forced ON state.

Next, the command "20" is read, and the data of the transaction-specific totalizer 37 is read. Next, the command “30” is read out, and the data of the transaction-based totalizer 24 and the data of the transaction-based totalizer 37 collected from each satellite machine 12 are totaled by type. Next, the command “40” is read, the printer 39 is driven, and the total data is output as a report. Finally, the command “FF” is read out, and the current inspection work ends.

As described above, according to the present embodiment, when performing the inspection work, the totalizer 2 for each transaction of each satellite machine 12 is used.
Since the main power supply of each satellite machine 12 is forcibly turned on only during a period required to collect the data of No. 4, each satellite machine 12 is forcibly turned on until the aggregated data is output as a report. Wasteful power consumption can be suppressed.

Each satellite machine 12 cannot perform the registration operation when the main power supply is forcibly turned on. However, according to this embodiment, the forced on period can be shortened. There is little risk of trouble and the processing efficiency is improved.

In the setting operation, first, an operation command "90" is set before the processing command for setting data in the transaction-specific totalizer 24 of each satellite machine 12, and then the transaction total of the master machine 11 is set. As long as the non-operation command “99” is set before the processing command for setting the data in the vessel 37 and the command sequence for the setting operation is set, the same operation and effect as in the inspection operation can be obtained.

In the above-described embodiment, the command string set in the command table 40 is sequentially read out by activating the command string as the command generating means. However, the present invention is not limited to this. A configuration in which commands are sequentially received may be used.

In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.
