Description

Detailed Description of the Invention (81 Technical Field) This invention relates to an electronic cash register having an item management table that stores item management data such as item code, unit price, unit price name, etc. for each item, and in particular, to changing the item management data. Concerning means.

(b) Prior art and its disadvantages In conventional electronic cash registers that have a single item management table that stores single item management data for each item, when change data to the single item management data is entered from the input key, the change data is immediately changed at the time of input. It was configured so that the single item management data could be changed. Therefore, for example, if the unit price of a certain item changes in the morning and afternoon, it is necessary to input data to change the unit price at the end of the morning, and it is not possible to input the changing data at any time, which is very inconvenient. there were. In addition, when changing unit price, unit price name, and other unit management data for many individual items at a certain time, it is necessary to centrally input the changed data all at once at that change time, which can cause mental and physical stress on the operator. In addition to increasing the burden, if there are a large number of items to be changed at that time, the input operation may take too much time, leading to the possibility that changes to some individual items may not be made in time.

(C) Purpose of the Invention The purpose of this invention is to enable the input of change data to single item management data in a distributed manner in advance of the point at which the change is necessary, and to automatically input change data at the time when the change is required. An object of the present invention is to provide an electronic cashier register in which change processing is performed.

fd) Structure and Effects of the Invention To summarize, the present invention is provided with a change data storage means for storing change data and a change time for changing the single item management data based on the change data, together with an item management table, and further measures the current time. A time clock means is provided, and when the changed time stored in the changed data storage means becomes approximately equal to the current time,
The single item management data is changed based on the change time and the change data stored in pairs.

With this configuration, according to the present invention, it is possible to input the change data in advance together with the change time, that is, the desired data change execution time at the time when the change data is generated, so that the change data can be inputted in advance at the time when the change is required. There is no need for intensive input, and the change is automatically performed when the change time comes, so the mental and physical burden on the operator can be reduced. Also, even if there are a large number of changes because there is no need for intensive input at once,
It is possible to prevent the occurrence of a situation in which the change of the single item management data for some single items cannot be made in time due to the input time.

The department key 11 can specify a total of five departments. The numeric keypad 12 is used to input the PLU code (product code), sales amount, etc. at the time of sale. Function key 13
The PLU key 13a is used when registering a PLU, the time key 13b is used when inputting change data, the identification key 13c is used, and the subtotal key 13 is used when calculating a subtotal.
d and a cash sales key 13e used at the time of sales.

FIG. 3 is a block diagram of a data management table including a single item management table, that is, the first storage means 6 shown in FIG.

This data management table DT includes a single item management table, an operator management table, a function management table, and a data buffer.

The single item management table has a section for storing the single item code, unit price, single item name, total sales of the single item, and number of sales of the single item for each item. For example, the single item code is “000000”
1" indicates that the unit price is "500", the single item name is "Kutsushita", the total sales is "49000", and the number of sales is "90".The data buffer stores the data input from the input key. DTiME, which is a temporary storage part and stores change time, that is, change execution time; BiD, which stores processing identification data to be described later; and PLU, which is a one-item code.
It is composed of B P L [J that stores codes and BN that stores numeric data.

FIG. 4 is a block diagram of the mailbox MB, that is, the storage means 70 shown in FIG. F. This mailbox MB is
For each item, time table level, processing identification stage, change data,
It has a storage area for processed flags. The time table M is for linking with the stored data of the time table TT shown in FIG. 5 (described later). The first digit of the processing identification field indicates the change target table, and "0" indicates the single item management table. The second digit represents the item to be changed and is “1”.
” indicates the unit price, and “2” indicates the unit name. The first data of the change data is the unit code, and the next data is the data of the item to be changed corresponding to the second digit number of the process identification. Process The completed flag is "O" to indicate unprocessed, and "1" to indicate processed.

FIG. 5 is a block diagram of the time table TT, that is, the storage means 71 shown in FIG. This time table TT has an area for storing table space, processing timing, and processed flag for each item. The timetable south is for linking with the mailbox MB shown in FIG. The processing timing is the change time (including date and time) of the single item management data input from the input key. The processed flag is "0" to indicate unprocessed, and "I" to indicate processed.

In the above configuration of mailbox MB and timetable TT, for example, the first data of mailbox MB is
Time table TT time table number 3 time “59”
11:30 am on December 20, 2019” Single item code
0000001" is changed to "socks".

Also, the second data in the mailbox MB is the single item code "00098" when the time in table I'b2 of the timetable TT becomes "December 25, 1959, 10:00".
Indicates that the unit price of ``50'' is to be changed to ``130Q''.If the unit price of ``50'' is changed to ``130Q''.
The processed flag of the corresponding time table in B and time table TT is changed from "0" to "l".

FIG. 6 shows an example of a key sequence for inputting change data and change time. In this example, “December 20, 1959”
Specifies that the unit code and unit price of “1230” should be changed to “225” at “11:30 am”.The data input by this key sequence is the number data before pressing the time key 13b, That is, the change time (execution time data) is temporarily stored in the data buffer BTiME,
The numeric data input before the identification key 13c is pressed, that is, the process identification information, is temporarily stored in the data buffer BiD. Further, the number data inputted before the PLU key 13a is pressed, that is, the single item code, is temporarily stored in the data buffer BPLU. Subsequently, when the numeric value and subtotal keys 13d are operated, the temporary storage data of the data buffer BTiME is set in the empty area of the timetable TT, and the processed flag at that position is set to "O". The timetable end of the timetable TT is set in the empty area of the mailbox MB together with the data stored in the data buffers BiD, BPLU, and BN. At the same time, the processed flag at that position is also set to "0".

Next, the operation of the electronic cash register will be explained with reference to FIGS. 7 and 8. FIG. 7 is a flowchart showing the operation when inputting change data and change time.

If there is a key input key, the process advances to nl”n2, and if the key input data is numeric data, the input data is stored in the data buffer BN at n3.If the key input key is not a numeric key, it is n4 to n7.
The key type is determined in . If it is the time key 13d, the data to be set is transferred to the data buffer BTiME at n9 on the condition that the data to be set is stored in the data buffer BN.

When the identification key 13c is pressed, n12 is entered on the condition that there is a time input in "0;" and the number is set.
transfers the number data to the data buffer BiD.

On the condition that there is an identification input and a number has been set before the time when the PLU key 13a is pressed, the set number data is transferred to the data buffer BPLU at n15.

When the subtotal key 13d is pressed, there is a PLU input before that, the first digit of the data buffer BiD is "0", the second digit is "1", and a number is set. , n20, the temporary storage data of the data buffer BTjME is set in the empty area of the time table TT, and the processed flag at that position is set to "0". Further, in n21, the temporary storage data of the data buffers BiD, BPLU, and BN at that time are set in the empty area of the mailbox MB, along with the timetable space of the timetable TT in which the temporary storage data of the data buffer BTiME is set. At the same time, the processed flag at that position is set to "0". After that, each data buffer is cleared and the process returns to the original nl.

By executing the key sequence as shown in FIG. 6 through the above operations, it is possible to record 1, 0 of the change data of the single item management data to be changed and its change time in the mailbox MB and timetable TT. .

FIG. 8 is a flowchart showing the operation of the single item management data change process executed by the in-flight timer interrupt. This operation is executed by a timer interrupt at regular intervals (for example, 15 minutes). First, at n30, the current time is read from the time clock means 3. Next, search the time table TT using the read current time and check whether there is any data whose time set in the table is before the current time and whose processed flag is "0". investigate. If there is no data matching the conditions, the process ends; if there is, the process proceeds to n33.

In n33, mailbox MB is searched using the timetable floor of timetable TT as a key, and the same timetable fish is set and the processed flag is "0".
”, the single item management data is changed based on the change data stored in that position.Furthermore, the processed flag of the changed data in the mailbox MB is set to “1”.Mailbox MB If there are multiple timetables that satisfy the conditions of n31 within the timetable, change processing of the individual item management data is performed for those multiple change data, and when all changes are completed, the corresponding timetable of timetable TT is changed. Set the positive processed flag to “1”
and exit.

In this embodiment, when searching the time table TT in n31 above, the setting time in the table is checked before the current time, but the operation by the timer interrupt shown in FIG. If it is performed every time, the process of n31 will ultimately check whether the set time (change time) is equal to the current time with an accuracy of minus 15 minutes. Therefore, the shorter the execution interval of the operation shown in FIG. 8, the more accurate the change time will be.
