Abstract

PURPOSE:To improve the operability of a data processor by changing a part of the storage contents by a simple operation and in a short time for transfer of data. CONSTITUTION:A master equipment U consists of a 1st memory means (buffer) 4, a 2nd memory means (buffer) 5, an operating means (key input part) 6, and a 3rd memory means (memory) 7. For instance, the data on the buffer 4 is stored in the memory 7 with a partial change. In this case, the data is sent to the buffer 5 from the buffer 4 with a change applied via the operation of the part 6. Then the data is transferred to the memory 7 from the buffer 5. Thus the data on the buffer 4 can be stored with a partial change into the memory 7 with a simple operation and in a short time compared with a case where the data on the buffer 4 is transferred to the memory 7 and then partly changed. As a result, the operability of a data processor is improved.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is directed to, for example, a sales management system that connects a main store and each store via an online line. The present invention relates to a data processing device that is suitably implemented in electronic cash registers and the like that process data.

Conventional technology Traditionally, the head office, central processing center, etc. and each store are connected through an online line, and sales data from the electronic cash register at each store is processed by a host combinator in the head office or central processing center, or by a host computer. From the unit price and department code of each product (hereinafter, products of the same category are represented,
(The smallest classification range to which the same unit price is assigned is called a department)
A sales management system has been implemented in which a host computer performs sales management for all stores at once by sending information such as cash registers to electronic cash registers at each store.

In such a sales management system, product data representing the unit price and department code of each product sent from the host computer is input into the buffer of a specific electronic cash register (hereinafter simply referred to as the master machine) at each store. Then, this product data is transferred from the buffer to the memories of the base machine and the slave machine of the electronic cash register (hereinafter simply referred to as slave machine) by operating keys on the base machine.

Conventionally, when you want to add or delete product data sent from a host computer, you transfer the product data sent from the host computer from the buffer of the parent device to the memory of the parent device and child device, and then The master device was operated to read out and change product data stored in the master device and its slave devices.

Problems to be Solved by the Invention In the base machine of such an electronic cash register, the i% association that changes the product data sent from the host computer has to store all the product data including the changed part in the m machine's key. It was necessary to enter the information manually using manual means, which was unnecessarily time-consuming.

An object of the present invention is to solve the above-mentioned problems, and to provide a data processing device that can transfer data by changing part of the stored contents with simple operation and in a short time, and has improved operability. It is to provide.

Means for Solving the Problems The present invention provides a first storage means for storing data, a second storage means to which data is transferred from the first storage means, and a first storage means for storing data from the first storage means or the second storage means. A data processing device comprising: a third storage means to which the data is transferred; and an operation means for changing the storage contents of the second storage means.

According to the present invention, for example, when it is desired to partially change the data in the first storage means and store it in the third storage means, the data is transferred from the first storage means to the second storage means, and the data is transferred to the second storage means. In the step, the operating means is operated to make changes, and then the data is transferred from the second storage means to the third storage means. Therefore, compared to transferring data in the first storage means to the third storage means and then changing part of the data, it is possible to change part of the data in the first storage means and transfer the data to the third storage means in a shorter time. can be memorized.

Embodiment ゛Figure 1 shows an electronic cash register U1~ of one embodiment of the present invention.
1 is a block diagram showing the configuration of a sales management system using Um. In a sales management system, for example, a host computer 1 is installed at the head office or central processing center, and product data such as the unit price and department code of each product is transmitted from this host computer 1 to the parent electronic cash register at each store. The information is transmitted to the machines U1 to Un (base machines U1 to Um are configured in the same way and are hereinafter collectively referred to as base machines U). The base unit U includes a buffer 4 as a first storage means, a buffer 5 as a second storage means, a key manual section 6 as an operation means, and a third
It is configured to include a memory 7 which is a storage means. In addition, each store has slave machines M1 to Mn, which are also electronic cash register machines, that perform so-called cash register operations together with the master machine U, and these slave machines M1 to Mn each include memories T1 to Tn. Ru.

Base unit U stores product data sent from host computer 1 in buffer 4 . On the other hand, for example, if each store wants to set its own unit price for a certain product.
When changing this product data, the product data stored in buffer 4 is transferred to buffer 5. buffer 5
can store data input from the key input unit 6, or change data stored in the buffer 5 by operating the key input unit 6. The data stored in the buffer 5 is transferred to the memory 7 of the main unit U by operating the key manual unit 6.
and are transferred to memories T1 to Tn included in slave units M1 to Mn, respectively.

If the product data from the host computer 1 is not changed, the data stored in the buffer 4 is transferred to the key human power section 6.
are operated to directly transfer the data to the memory 7 and the memories T1 to Tn of the slave units M1 to Mn, respectively.

FIG. 2 is a flowchart for explaining the operation of the base unit U of the electronic cash register. When product data from the host computer 1 is stored in the buffer 4 of the base unit U, when such product data is transferred to the memory 7 of the base unit U and the memories T1 to Tn of the slave units Ml to Mn, Then, the process moves to step n1.

In step n1, if it is desired to change the product data in the buffer 4, the process moves to step n2.

At step n2, the buffer 4 is
Product data is transferred from the buffer 5 to the buffer 5.

Thereafter, in step rI3, the key human power section 6 is operated to make changes such as additions and deletions to the product data in the buffer 5.

In step n4, the buffer 5 is
The contents stored in memory 7 and each slave unit M1 to M
rr's memories T1 to Trr.

When it is not necessary to change the product data stored in the buffer 4 in step n1, the process moves to step n5 and by operating the key human power unit 6, the product data stored in the buffer 4 is directly transferred to the memory 7 and It can also be transferred to the memories T1 to Tn of the mustard fiM1 to Mn.

In this embodiment, when it is desired to change the product data sent from the host computer 1, the main unit U
memory 7 and memories T1 to Tn of each slave unit M1 to Mn
It is possible to transfer the data to the buffer 5 and change its contents by operating the key manual section 6 before transferring the data to the buffer 5. Therefore, after the transfer to memory 7 and memories T1-Tn,
Compared to changing the product data, it is possible to change the product data with a simpler operation and in a shorter time, and therefore, the so-called interruption time of register registration can be shortened.

Effects As explained above, according to the present invention, for example, when data in the first storage means is partially changed and stored in the third storage means, C1 the data is transferred from the first storage means to the second storage means, Changes can be made by operating the operating means, and then the data can be transferred from the second storage means to the third storage means. Therefore, changing part of the data in the first storage means is easier and faster than transferring data in the first storage means to the third storage means and then changing part of the data. and can be stored in the third storage means, improving operability.
