Abstract

PURPOSE:To extremely reduce the memory capacity by setting the data after compressing it when the data is identical with the data which is already set in accordance with other sorting. CONSTITUTION:In a set mode to a sort-based memory 1, a discriminating device 2 retrieves the memory 1 for each input of the preset data and discriminates whether the data identical to the input data is set at the memory 1 or not. If not, a setting device 3 secures a standard area of the prescribed length decided previously in accordance with the input preset data in the memory 1. Thus the input preset data is set in the standard area. Meanwhile a 2nd setting device 4 secures an area in the an area in the memory 1 by reducing the standard area corresponding to the input data by a degree equal to a size set previously when the data identical to the preset data is inputted to the memory 1. Then the link data related to the sort of the same data is set in the reduced area.

Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a sales data processing device such as an electronic cash register, and more particularly to a sales data processing device that sequentially sets presets and data input for each category in a memory for each category. [Prior Art] Conventionally, an electronic cash register (ECR) is provided with a FLU memory or the like for storing sales data for each product. Figure 10 is a partial diagram of a conventional FLU memory, showing the data format for one record (lm items). That is, data for one record is stored in memory Nb (FL
It consists of U code), character (product name), unit price, quantity, amount, and other setting data. here,
2 bytes for memory, 12 bytes for characters, 3 bytes for unit price, 3 bytes for 4WIa, 5 bytes for amount, 5 bytes for other setting data, that is, a predetermined capacity that is determined in advance according to the type of data. area will be secured. Therefore, an area of 30 bytes is fixedly secured in the FLU memory corresponding to the l record. [Problem to be solved by the invention] In this way, in the past, 30 bytes per product, so if the number of products was r5 0 0, 15,000 bytes were required for the FLU memory, but However, there was a drawback that there was a large portion of the same data and the memory could not be used efficiently. The reason for this is that the data corresponding to each classification is treated as fixed data with a uniform 30-byte structure. If the data set for each classification is the same as the data already set for other classifications,
It is clear that memory can be used more efficiently by avoiding duplicate settings for the same data and compressing and setting the data corresponding to the relevant classification. An object of this invention is to avoid duplicate settings of the same data and to compress and set the data when it is the same as data that has already been set corresponding to another classification.

[1,000 Steps to Solve the Problem The means of this invention are as follows. The classification memory l (see the functional block diagram in Fig. 1, the same applies hereinafter) is, for example. This is a FLU memory that stores FLU codes, characters, unit prices, quantities, amounts, and other setting data. The discriminating means 2 stores data (FLU code,
character, unit price, etc.), it is determined whether the same data as the input data has already been set as preset data for another category in the category memory l. The first setting means 3 stores a standard area of a predetermined length corresponding to the input data in the memory for each classification when it is determined in the discrimination step 2 that the same data is not set. 1, and then set the input preset data to the standard area. Here, the standard area of predetermined length is a fixed length that is predetermined according to the type of preset data, such as 2 bytes for FLU code, 12 bytes for character, and 3 bytes for unit price. This is the area. The second setting means 4 secures a reduced area in the classification memory l by reducing the standard area of the predetermined length when it is determined in the discrimination stage 2 that the same data is set. , set link data to be associated with the same data classification in the reduced area. Here, the reduced area is an area obtained by reducing a standard area of a predetermined length, and is an area of a fixed length whose reduced size is fixed in advance according to the type of preset data. [Function] The function of the means of this invention is as follows. Now, it is assumed that the FLU code, character, unit price, and other necessary data are sequentially set for each product in the classification memory l, for example, the FLU memory. In this setting mode for the classification memory 1, the determining means 2 searches the classification memory 1 every time preset data is input, and determines whether the same data as the input data is set in the classification memory 1. Determine. Here, if the same data is not preset in the classification memory l, the first setting means 3 sets a standard area of a predetermined length corresponding to the input preset data in the classification memory l. After securing, set the input preset data to the standard area. Therefore, for example, when a FLU code is input, a 2-byte standard area is secured and the FLU code is set in that area. Also. When a character is input, a standard area of 12 bytes is secured and the character is set in that area. On the other hand, if the same data as the data already preset in the classification memory l is input, for example, if the same unit price as for another classification is input, the second setting means 4 After securing a reduced area (1 byte) in the classification memory l by reducing the corresponding standard area (3 bytes) by a predetermined size, link data that is associated with the same data classification is placed in the reduced area. Set. Therefore, if the data is the same as data that has already been set for another classification, it is possible to compress and set the data while avoiding duplicate settings of the same data. [Example] An example will be described below with reference to FIGS. 2 to 8. Figure 2 is a block diagram showing the basic structure of ECR. The CPU II controls various operations of this ECR according to microprograms stored in the ROM 12, and imports sales data input from the key human power section 13 via the input control section 14, and executes various operations constituting the RAM 15. Along with registering to the sales totalizer, display drive s16,
The information is supplied to the print control section 17 to cause the display section 18 to output a display, the printing section 19 to output a printout, and furthermore to control the opening operation of the drawer 20. In addition to the various keys usually provided on the keyboard of the key control unit 13, such as a numeric keypad and function keys, there are also characters (product name),
There is a character key to input characters when setting the quantity, amount, FLU code, and unit price, a quantity key to input the quantity, an amount key to input the amount, a FLU key to input the FLU code, and a unit price key to input the unit price. A mode switch MS is provided for switching between various modes. Note that the mode switch MS is set to "P (setting)", "rREG (registration)", etc. depending on its switching position. r
oFp (power off), rz (inspection), rz (payment)
This is a control lock that switches between each mode.
In addition, in this embodiment, the learning function described later is turned on/off.
A slide switch SD is provided to turn it off. Here, the learning function means that when setting data to the sales totalizer in the RAM 15, it checks to see if it is the same data that has already been set, and if the data has already been set, special settings are made. This is a function that allows you to do this. RAM 15 stores various sales totalizers, namely FLU memory 15.
-1, department memory l5-2, etc. FIG. 3 is a partial configuration diagram of the PLU' memory 15-1.
It shows the data format for 1 record (for 1 product). That is, the data for 1 record has the data length, memory Nb (FLU code), character (product name), unit price, quantity, amount, etc. at the beginning. Setting data (link department destination,
It consists of the number of authentications, 0 unit price, etc.). here,
Data length is 1 byte, memory is 2 bytes, characters are 12 bytes, unit price is 3 bytes, quantity is 3 bytes, amount is 5 bytes, other setting data is 5 bytes, that is,
An area with a predetermined capacity is secured depending on the type of data. Of each data in the l record, the number of items and the amount are updated when sales data is registered, but other data is setting data arbitrarily set by the user. Note that the data length indicates the length of one record. Also, data length, characters, number,
The area corresponding to the amount is a fixed area, but the area corresponding to the unit price and other setting data is an area that can be reduced as necessary. In other words, when presetting unit price, FLU
If the same unit price has already been set in the memory 15-1, the standard area (3 bytes) predetermined according to the unit price is changed to a reduced area (1 byte).
(See Figure 4). Also, if the same data is already set in FLU memory l5-1 when presetting other setting data, the standard area (5 bytes) predetermined corresponding to that setting data will be reduced. Small area (
1 byte) (see Figure 5!'!!). Next, the operation of this embodiment will be explained with reference to FIGS. 6 to 8. FIG. 6 is a flowchart showing the operation when setting data in the FLU memory 15-1. In this case, when the FLU memory 15-1 is specified in the setting mode in which the mode switch MS is set to the switching position "P", the memory setting process according to the flowchart of FIG. 6 is started. First, the presence or absence of data input is checked (step Al), and if there is no data input, it is checked whether the setting mode has been canceled (step A2). Here, under the setting mode,
Return to step AI and wait while repeating steps AI and A2 until data is input. Now, if you input 1 record's worth of reset data, that is, data length, memory output, character, unit price, and other setting data, the input 1 record's worth of data will be temporarily stored in input buffer IB ( Step A3). After entering all the setting data, first,
The CPU II reserves a data length area (1 byte) in the FLU memory 15-1 and sets the data length to the area (step A4). Next, secure a character area (12 bytes) and set a character in the area (
Step A5). Next, the on/off state of the slide switch SD, that is,
Check the on/off status of the learning function (step A6).
Here, if the learning function is turned off, the process proceeds to step A9, where a unit price area (3 bytes) is secured and a unit price is set in the area. On the other hand, if the learning function is turned on, the unit price in the FLU memory 15-1 that has already been set is searched, and the same data as the input unit price in the input buffer IB is found in the FLU memory 15-1.
Check whether the file exists in the LU memory 15-1 (step A7). Here, if the same unit price does not exist,
Proceeding to step A9, a standard area for 3 bytes is secured and data is set in that area. However, if the same unit price has already been set, a reduced area (1 byte) is created by reducing the standard area (3 bytes). ) is secured, and the address of the destination FLU for which the same unit price is set in this reduced area is set as link data (step A8). Next, proceed to step AIO, secure the number area (3 bytes), and secure the amount area (5 bytes) (step A
ll). After that, check the on/off status of the learning function again (step A12), and if it is turned off, proceed to step Al5,
Allocate a setting data area (5 bytes) and write the setting data to that area. On the other hand, if the learning function is turned on, the process advances to step Al3, and it is checked whether the same setting data has already been set in the FLU memory 15-1.
Here, if the same data has not been set, the process advances to step A15, but if the same data has already been set,
A reduced area (1 byte) is secured by reducing the standard area (5 bytes), and the address of the destination FLU in which the same data is set in this reduced area is set as link data (step A14). Then, the process returns to step A1 and the above-described setting process is repeated record by record. FIG. 7 shows the data format set in the FLU memory 15-1 in this way. here. Fi4
Medium rPG! l is link data. Note that when the unit price area is reduced, there will be a 2-byte empty area, and when the setting data area is reduced, there will be a 4-byte empty area, but in this case, each record data will have a gap between them. It is remembered completely. Figure 8 is a flowchart showing the operation when registering sales data. First, in the registration mode in which the mode switch MS is set to the switching position "REGJ", when a FLU-specific registration operation is performed according to the normal key operation procedure, the FLU memory 15-1 is stored in the FLU memory 15-1 with the FLU code input accordingly. In this case, it is checked whether it is the FLU code of memory Nbl (step B2), and if it is the FLU code of memory NOl, data for the first l records is read out according to this data length. but(
Step B3), if it is a FLU code of memory Ft)2 or later, proceed to step B4, and add the data length up to the (n-1)th record in order to read the nth record indicated by memory "n". Read the data from the address value obtained by doing this to the address value indicated by the nth data length. Then, the process proceeds to step B5, and it is checked whether link data is included in the read data for l records. Here, if link data is included instead of unit price data or if link data is included instead of other setting data, this is detected in step B5 and the process proceeds to step B6. The FLU memory 15-1 is searched using the address indicated by the link data, and the unit price or other setting data in the record is read. Once the data for one record to be registered has been collected in this way, the process proceeds to the next step B7, where normal registration processing and arithmetic processing are executed. Although the above embodiment avoids overlapping settings of the same data between FLU data, it is also possible to avoid overlapping settings of the same data between the FLU memory 15-1 and the department memory 15-2. In this case, FIG.
This shows the data format for one record in 5-2. That is, one record of data in the department memory 15-2 is composed of a department code, quantity, price, and other setting data. If the other setting data corresponding to a certain FLU code in the FLU memory 15-1 is the same as the other setting data in the department memory 15-2, the other setting data area corresponding to the FLU code is Set the department address as link data. and. At the time of FLU registration, the department memory 15-2 may be searched according to the link data, and other setting data corresponding to the department code may be read out. Furthermore, during PLUfi recording, it may be determined whether link data is included in an l record based on the data length. In this case, the data length of a record that does not include link data is 31 bytes, 30 bytes if link data that replaces the unit price, and 30 bytes if link data that replaces other setting data is included. is 29 bytes, and 2 if link data that replaces the unit price and other setting data is included.
If it is 8 bytes, it is possible to determine the presence or absence of link data based on the data length. Also, the link data is F
It may be an LU code or a department code. [Effects of the Invention] According to the present invention, when data is the same as data that has already been set corresponding to another classification, in order to avoid duplicate settings of the same data and compress and set the data, Memory capacity can be significantly reduced, making it possible to use memory efficiently.
