Description

[Detailed Description of the Invention] The present invention relates to an electronic cash register that is capable of classifying a large number of product section totalizers into a plurality of groups and automatically tallying sales for each group. It is something.

Unlike mechanical cash registers, the number of totalizers in electronic cash registers can be increased relatively easily, and sales management is required to be more sophisticated. There is a tendency for the number to increase significantly. However, the number of product departments is too fragmented,
As a result of increasing the number of totalizers, the task of tabulating sales has become more complicated and more time-consuming than before. The present invention focuses on this point, and makes it possible to reorganize a large number of subdivided product departments into groups consisting of arbitrary plurality of product departments, and to automatically perform sales aggregation for each group. The purpose of this invention is to eliminate the complexity of the sales aggregation work.

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2.

Next, the group function according to the present invention will be explained separately for each operation mode. (1) Preset mode The preset mode is a group number setting mode in which a large number of product departments are reorganized into arbitrary groups consisting of a plurality of items, and a group number for identifying each group is registered in the group number storage section 33 of each department totalizer 15a. It is.

First, the mode switch 5 is set to the group set position.
As a result, the group set signal from the mode switch 5 is applied to the flip-flop (G.S.FF) of the key signal control device 6.
), and the group set display lamp on the display device 13 lights up. Next, a group number arbitrarily selected from among the numbers O to 15 is input into the cash register by pressing the numerical key 2 on the keyboard.

The group number is from O to 1 when pressing number key 2.
It consists of two digits up to 5, but the divisional totalizer is 15
When stored in the group number storage section 33 of a, 1 digit 4
Stored in a binary configuration of bits. The gnome number pressed by the numerical key 2 is stored in the eighth digit from the bottom of the Z register 7 and the X register 8 via the key signal control device 6, and is further displayed on the display device 13 via the input/output control device 12. be done.

At this time, the arithmetic unit 11 checks the group number under the control of the group set signal, and if the number is 16 or more, it disables the machine and lights up the error indicator lamp on the display unit 13. Next, one of the department keys 1 is pressed to specify the product department to be included in the group.
The department number of the pressed department key 1 is stored in the 9th and 10th digits from the bottom of the X register 8, and is further displayed on the display device 13. At the same time, the department number stored in the X register 8 is used to address the corresponding department of the department totalizer 15a through the address control device 15X of the storage device 15. The contents of the eighth digit from the bottom of the addressed department totalizer 15a are read out from the bottom of the X register 8 under the control of the arithmetic unit 11. The group number previously stored in the eighth digit from the bottom of the X register 8 is transferred to the eighth digit from the bottom of the X register 8 via the Y register 9. 8 from the bottom of the X register 8 to which group numbers have been added in this way
The contents of the digits are re-registered in the department totalizer of the corresponding department, and the setting of the group number is completed. At this time, only the department number stored in the X register 8 is displayed on the display device 13, and the group number and department number are printed on the printer 14. By successively pressing the department keys of the product departments desired to be included in the same group, the contents of the department totalizer specified by the department key are read out to the The group number is added and the group is set. This operation can be arbitrarily performed for as many groups as desired. Also, if you want to reset the group number storage section 33 of all department totalizers 15a to O, first press O from numeric key 2, then press automatic key 17, and all group numbers will be automatically reset. It turns out. If you want to change the group number, in order to prevent sales from different groups from being mixed in as sales from other groups, make sure that the department totalizer you want to change has been settled and has not been registered since then. Total unit sales storage unit 31 and total sales amount storage unit 32
The group number can be changed only when and is O.
That is, the arithmetic unit 11 inputs the data from the divisional totalizer to the X register 8.
Check the total sales number and total sales amount read out,
The group number preset operation is performed only when the flag is O. If it is not O, the read memory contents are returned to the original department totalizer, and the machine is stopped at that point. Therefore, in order to operate the cash register next time, the user must press the reset button to reset the stopped state.

(2) Registration mode In order to operate the cash register in the registration mode, the mode switch 5 is set to the registration position.

In this mode, when the department key 1 corresponding to the sales item is pressed, the department totalizer 15a is addressed, and the group number is displayed in the is read out. After the operation, the contents of the X register 8 are written back to the original division totaler together with the group number. The group number read here is used for the group number inspection function described below. [Group number inspection function] The group number can be used as a special function.

One example is a function to disable unused department keys (unused department keys). For example, if the number of departments for products to be used is small, the number of usable department keys is greater than the number of product departments, so there are department keys that should not be used. If the operator presses an unused department key by mistake, the cash register performs normal calculations, adds the amount, etc. to the erroneously addressed department totaler, and then performs normal registration operations.
In sales aggregation, it becomes unclear which product department the contents of the erroneously stored department totalizer belong to, and an error occurs in the aggregation. In order to prevent such errors from occurring, it is necessary to prevent the cash register from operating when an unused key is pressed. As one aspect of its use, the group number according to the present invention is used as an identification number of an unused department key to prevent the operator's operation error as described above. can. For example, group number [1
5" is used as the identification number, and "15" is stored in advance as the group number in the unused department totalizer.

When the operator presses an unused department key during registration, the contents of the corresponding department totalizer 15a addressed by the department number of the department key are transferred to the X register 8. The arithmetic unit 11 checks the group number read into the X register 8. When it is recognized that the group number is [15], the arithmetic unit 11 returns the contents of the X register 8 to the department totalizer 15a as is, and
Closing cash registers. As a result, it is possible to prevent amounts from being erroneously registered in department totalizers that are not in use. Moreover, since there is no display or printing that gives the illusion that the cash register is operating normally, the operator is made aware that the currently pressed department key 2 is an unused department key. I can do it. Subsequent registration operations can be continued after pressing the reset key.

(3) Group aggregation method in settlement/inspection mode The group aggregation method in settlement or inspection mode is the same for both, so the settlement mode will be explained below.

Group payment (payment by group number) includes individual payment by specifying a group number and automatic continuous payment (automatic payment). In the individual settlement mode, only the section totals of the product sections belonging to the group designated by the numerical key 2 are settled, and in the automatic settlement mode, the group-by-group settlement of all the product section totalizers 15a is performed automatically and continuously. First, the individual payment order will be explained. The mode switch 5 is set to the payment position (inspection position in the case of an inspection operation), and the group number is designated by pressing the numerical key 2. Next, when the group key 16 is pressed, the pressed group number stored in the z register 7 (hereinafter referred to as reference group number) is stored in the reference group number register 11c in the arithmetic unit 11 as a group signal generated from the group key 16. is stored in the group settlement flip-flop (FF) 11D. The reference group number is used to identify the group numbers stored in each department totalizer 15a, and the group signal controls the arithmetic unit 11 to perform group-by-group settlement operation. In the arithmetic unit 11, a department number register 11E is provided which counts up from 1 to 60 and specifies the address of the department totalizer 15a, and reads the contents of the department totalizer 15a sequentially from addresses 1 to 60 into the x register 8. X
The group number contained in the group number storage unit 33 read out in the register 8 is compared with the reference group number in the adder 11A, and only when the two match, the sales total of the department is read out in the X register 8. The amount and the total number of sales are added to the itemizer 15b of the storage device 15. If the group numbers do not match, the contents of the department totaler 15a read into the X register 8 are returned to the original department totaler 15a. In this way, the group numbers of all 60 department totalizers 15a are checked, and the total sales amount and total number of sales of the department totalizers 15a belonging to the same group number are totaled in the itemizer 15b.

The printer 14 prints the department number of the product department belonging to the designated group, as well as its total sales amount and total sales number, and finally prints the designated group number, the total sales amount, and the total sales number of that group. . The display device 13 simultaneously displays the same numbers as those printed by the printer 14. When all of the above-mentioned operations are completed, the total sales amount, total number of sales, and contents of the itemizer 15b of each department totalizer 15a of the processed product department are returned to zero. Alternatively, in the inspection mode, only the contents of the itemizer 15b are returned to zero. As is clear from these results, the individual settlement by group is particularly useful when changing the group number, and the individual inspection by group is mainly used for sales inspection by group. Automatic payment is a payment operation in which payment is automatically made for all product categories by group by simply setting the mode switch 5 to the payment mode and pressing the automatic key 17, without specifying the group number.

The calculation method for payment and the order and method of printing and display are the same as in the case of individual payment, but the difference is that automatic payment is performed consecutively for each group. When the payment operation is started by pressing the automatic key 17, first, the reference group number register 11c is automatically set to 1, and the group number 1 is set to 1.
A settlement operation similar to the individual settlement operation is performed for each group, and after the completion of the settlement operation, the reference group number register 11c is counted up to 2 and the settlement operation for group 2 is performed. In this way, the reference group number register 11c is sequentially counted up to 14, and during this time the settlement operation for each group is performed. The contents of the itemizer 15b are added to the totalizer 15d each time the settlement operation for each group is completed, and each time it is returned to zero, in preparation for the addition of the next group. Display device 1
3 and the printer 14 print and display the total sales amount and total sales number stored in the totalizer 15d after the settlement operation of the group 14 is completed. The totalizer 15d is then reset to zero, and the automatic settlement operation ends. Thus, the electronic cash register according to the present invention can divide a large number of product departments into a small number of groups, thereby making it possible to perform settlement and inspection for each group, thereby greatly improving the efficiency of sales tabulation work.
