Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic cash register having a totalizer for each product category and a totalizer for each person in charge, and capable of processing registered data for each product category and each person in charge.

Conventionally, this type of electronic cash register has been equipped with a memory for setting totalizers for each product category and a memory for setting totalizers for each person in charge, so that any number of totalizers can be set in the dedicated memory for each. It is being

However, with such a device, it is fine if the totalizer is fully set in each dedicated memory, but in a market where the business is run by a small number of people, for example, one or two people, the number of totalizers set by each person in charge may be limited. Therefore, there is a drawback that the non-protocol part of the dedicated memory of the totalizer for each person in charge is wasted.

In addition, in such a device, the number of totalizers that can be set for a dedicated memo is determined by the memory capacity limit. For example, if there are a particularly large number of product categories or a particularly large number of persons in charge, There was a drawback that they could not deal with it. This invention was devised in order to eliminate these drawbacks, and provides an electronic cash register that can effectively and efficiently set product classification weak U totalizers and person-specific totalizers in memory. The purpose is to provide.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the external appearance, and 1 is the main body of the cash register.

The cash register main body 1 has an operator display 2 at the top, a keyboard 3, a control switch 4, a receipt issuing port 5, a journal inspection window 6, and a memo holder 7 at the center, and a drawer 8 at the bottom. ing. Incidentally, a cashier table 9 is provided above the drawer 8. A customer display 10 is attached above the husband part of the cash register main body 1. The operator display 2 and the customer display 1
For example, as shown in FIG. 2, 0 is formed by a department display 10a, an amount display 10b, and a process content display 10c such as registration, bunch, and subtotal.

The control switch 4 controls the power on/off by inserting a key into the insertion slot and rotating it, and also commands the central processing circuit to perform the tasks of "return registration,""registration,""inspection," and "settlement." This is a control switch for Note that the above-mentioned "registration" refers to the task of storing the price of the product, etc. in the storage section of the register body, and printing out the results on receipts and journals. In addition, "return registration" refers to the process of storing the amount of the returned product, etc. in the memory section of the register when a previously "registered" product is returned, and printing out the results on the receipt and journal. say. Furthermore, "inspection" refers to the task of printing out the total sales amount, total sales points, etc. cumulatively stored in the storage section of the register main body through the "registration" on receipts and journals. Also"
"Settlement" means, for example, at the end of a day's work, the total sales amount, total sales points, etc. cumulatively stored in the memory section of the register body by the "registration" mentioned above are printed out on receipts and journals, and the contents of the memory section are cleared. refers to the work that is done. Furthermore, "setting" refers to the task of setting the totalizer, etc. to be used depending on the purpose. The keyboard 3
As shown in Figure 3, the direct number keys 1, 1, ``Free'', ``Haruto'', ``Department/Product Number'', ``9'' and ``00'' are shown in Figure 3.
Function keys 1 for ``Deposit'', ``Register/Cash Total'' etc.
2 is provided. FIG. 4 is a block diagram showing the circuit configuration. A central processing unit (CPU) 13 includes an arithmetic circuit, a program counter, a control circuit, an instruction recorder, a command register, etc., and each of the keys 11,
Based on the 12 input signals, various arithmetic processes, the storage section 14, and the input/output device 15 are operated.

The storage unit 14 has nine registers that store fixed data such as programs for each operation of this register, such as "registration,""inspection,""accounting," and "setting etc." as described above.
Only memory (ROM) 16 and 12 random access memories that store variable data such as product prices, product classification symbols, sales numbers by product classification and person in charge, construction cost, etc. (RAM) 17.

The data in each of these ROMs 16 and RAM 17 is exchanged with the central processing unit (CPU) 13 through an address bus 18 and a data bus 19, respectively, and at the same time, the timing control thereof is selected through a ROM selector 20 and a RAM selector 21. This is done using control signal lines 22 and 23 that are inputted to the control signal line.

The input/output device 15 includes three output ports 2 connected to the central processing unit (CPU) 13 through the data bus 19.
4, 25, 26, one input board 27, and a keyboard display circuit 28, each of which receives a control signal line 29 from the central processing unit 13.

The signal from the output boat 24 is input to the drawer opening device 3, and the drawer 8 is opened after the calculation is completed. Further, various timing clocks from the output port 25 are input to each circuit or device constituting the input/output device 15, and control the timing of information exchange with the central processing unit 13. Furthermore, signals from the output port 26 are input to a printer drive circuit 31, which controls the printing operation of a printer 32 that prints various calculation results on receipts or journals. Note that the printer drive circuit 31 includes the output boat 24.
A feed signal fe for feeding receipts and journals and a cut signal Cu for cutting the receipt when the receipt has been fed a predetermined number of lines are input, respectively. The input boat 27 carries out the five operations described above, namely "return registration", "registration" and "inspection".
A signal from the control switch 4 for switching programs for each job such as "accounting" and "setting" is input, and based on this signal, the entire apparatus is designated for each job by the program stored in the ROM 16 of the storage unit 13. That is, it is set to tasks such as "registration" or "inspection."

Also, keyboard display 28 has keyboard 3.
and display device 2, lm are connected. In addition, 33 is a power supply circuit that supplies operating voltage to each circuit of this device;
4 is its power failure detection circuit. FIG. 5 shows a memory formed by the RAM 17, in particular a memory for setting a totalizer by product category and a totalizer by person in charge, and this memory has, for example, memory addresses "1" to "30" It has capacity.

Then, in this memory, totalizer A by product category is set in order from the address with the smallest address to the highest address, and totalizer B by person in charge is set in order from the address with the largest address to the smallest address. It has become. The setting of the product classification U totalizer and the person-in-charge totalizer for the memo IJI shown in FIG. 5 is performed by the circuit shown in FIG. 4 based on the flowchart shown in FIG. 6.

i) Setting of Totalizer A by Product Classification As shown in a of FIG. 6, first set the control switch 4 to "setting".

Next, the user inputs the product classification code using the numerical keys 11 of the keyboard 3, and operates the "Department Product Number" key within the function keys 12. Then, the central processing unit 13
A program for setting the totalizer for each product category is called from 16, and based on that program, writing of the product category code to the setting memory in the RAM 17 is controlled. First, whether or not there is space in the memory is checked in order from the smallest address as shown by the solid arrow in FIG. If there is space, the product classification code input to the code setting section of that address is written, and the product classification totalizer is set. If there is no free space, it is determined that the memory is full and an error is processed.
ii) Setting of totalizer B for each person in charge As shown in FIG. 6b, first set the control switch 4 to "setting".

Subsequently, the person in charge code is digitized using the direct number keys 11 of the keyboard 3, and the "yellow" key within the function keys 12 is operated. Then, the central processing unit 13 calls a program for setting the totalizers for each person in charge from the ROM 16, and based on that program, controls the writing of the person in charge code into the setting memory in the RAM 17.
First, it is checked whether there is space in the memory or not, starting from the address with the largest address, as shown by the dotted arrows in FIG. If there is space, the person in charge code input to the code setting section of that address is written and the totalizer for each person in charge is set. If there is no free space, it is determined that the memory is full and an error is processed. Note that the purpose of pressing the "department/product number" key and the "yellow" key is to determine whether the code numbered by the calendar number key 11 is a product classification code or a supervisor code. Like this 1
Since the product classification missing totalizer is set in order from the smallest address for each memory, and the totalizer for each person in charge is set in order from the largest address, the setting of the totalizer for each contributor is When the number is small, you can set more product classification totalizers, and conversely, when the number of product classification totalizers is small, you can set more totalizers by person in charge. This allows memory to be used effectively depending on the purpose without wasting it.

In this regard, in the conventional system, the permissible number of settings for the product classification porridge U totalizer and the permissible number of settings for the totalizer for each person in charge are set in advance.For example, when the number of settings for the totalizer for each person in charge is small, the remaining The address was unused and wasted. In the above embodiment, the product classification current U totalizer is set in order from the smallest address in the same memory, and the person-in-charge totalizer is set in order from the largest address, but this is not necessarily the case. The present invention is not limited to this, and the product classification totalizers may be set in the same memory in order of increasing addresses, and the person-in-charge totalizers may be set in the order of decreasing addresses.
As detailed above, according to the present invention, one of the totalizers for each product category and the totalizer for each person in charge is set in the same memory in order from the one with the largest address, and the other one is set in the order from the one with the smallest address. By setting the cash register in sequence, an arbitrary number of stages can be set for each, so we provide an electronic cash register that can efficiently and effectively set the product classification totalizer and the person-in-charge totalizer in the memory. It is possible.
