Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic monetary registration apparatus adapted to transmit and receive monetary registration information from one or a plurality of electronic monetary registration machines to a processing device such as a host computer.

[0002]

2. Description of the Related Art FIG. 9 is a diagram showing a configuration of a conventional electronic cash register B, in which one or a plurality of electronic cash registers 92 are preset data to a host computer 91 which is a common processing device. , For example, call a unit price
LU, Price LookUp) unit prices and texts corresponding to codes, setting data such as product names, and various types of monetary registration data related to sales stored in the memory for each sales are transmitted via the communication unit 93.
Data collection and analysis are performed on the host computer 91 side.

In such a prior art, the following operation is generally performed. FIG. 10 is a diagram showing transmission and reception of sales data for each PLU code between the host computer 91 represented by HC and the electronic cash register 92 represented by ECR. First, as indicated by arrow 94, a signal requesting transmission of sales data for each PLU code is sent to the electronic cash register 9
2, and the electronic cash register 92 transmits the data of the number of sales and the amount of sales relating to the first PLU code 1 out of the n PLU codes to the host computer 91 as indicated by arrow 95. Next, as indicated by the arrow 96, the data of the sales quantity and the sales amount of the second PLU code 2 are transmitted, and this operation is sequentially repeated,
As indicated by the arrow 97, the data up to the nth PLU code n is transmitted.

[0004]

In such a conventional technique, even if only the sales quantity data of the sales data for each PLU code is required, only the sales quantity data is stored in the electronic cash register 92. There is no function to send,
The data of the sales amount is also transmitted to the host computer 91 together with the number of sales, and the host computer 91 performs arithmetic processing such as tabulating only the data of the number of sales among the transmitted data. That is, there is a problem in that unnecessary data that is not the target of aggregation or analysis by the host computer 91 is transmitted, and the transmission time is unnecessarily lengthened.

The reason why flexible transmission conditions cannot be set in this way is that there are dozens of types of data even with sales data by PLU code alone, and various types of transmission conditions must be set for various types of data. Not only that, the number of operation programs of the electronic cash register 92 increases unnecessarily, which complicates programming and also increases the storage capacity of the required memory, which requires expansion of the storage capacity. is there. Therefore, providing the electronic cash register 92 with a function of transmitting only necessary data leads to an increase in cost, and as described above, data transmission is performed according to a predetermined combination of data. Is.

An object of the present invention is to provide an electronic cash registering device which receives only information required by a processing device such as a host computer from an electronic cash register and performs arithmetic processing such as counting. That is.

[0007]
