Abstract

PURPOSE:To prevent cash money deposited by a customer from being stored in a drawer until a time when change is delivered to the customer by issuing an alarm when the kind of a note inputted/outputted to the drawer first exceeds the change in a state where a calculated change amount is displayed on a display part. CONSTITUTION:A CPU 41 discriminates a job mode selected by a mode switch 22 when key input is performed from a keyboard 12, and executes a key processing. When a cash calculation key is inputted, after the fact that a mode is set at a registration mode and that a product is now on sale and registration being confirmed, it is judged whether or not the registration is performed just before. And when the registration is performed, since registered data shown the amount deposited by the customer, change calculation to subtract a total amount from the deposited amount is performed, and calculated change is displayed on display devices 14 and 15. Next, a money case is opened via a drawer opening device 51, and only a receipt is issued from a receipt issuing opening, and the kind of note and the change inputted/outputted from the money case are compared and when the kind of note exceeds the change, a buzzer 49 is activated.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to electronic cash registers.

[Prior Art] Normally, when a cashier who operates an electronic cash register receives a payment of more than the total amount from a customer, he places the cash on the cashier table installed in the electronic cash register and records the received amount, also known as the deposit amount. Enter the current total key.

Then, in the electronic cash register, change calculation is performed to subtract the deposited amount from the total amount, and the calculated change amount is displayed on the display section.

The cashier then takes out the change from the drawer according to the instructions and hands it to the customer along with the issued receipt.

With this, the accounting operations for one customer are completed.

However, sometimes the cashier first stores the cash received from the customer in the drawer, then enters the deposited amount and calculates the change. In such a case, it is not possible to check the amount deposited at the time of handing over the change, so even if the customer claims that the change is incorrect, it cannot be proven, leading to problems. For this reason, the cashier must be careful not to put the deposit received from the customer in the drawer until the cashier has given the change.

[Problems to be solved by the invention] However, in the conventional electronic cash register,
There was no function to prevent cashiers from storing cash deposited by customers in the drawer before handing over change, which caused problems with change.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide an electronic cash register that can prevent the cashier from storing the cash deposited by the customer in the drawer before handing over the change, and can suppress the occurrence of troubles related to change. be.

[Means for Solving the Problems] As shown in FIG. The electronic cash register calculates the change amount 5 by subtracting the total amount 2 from the deposit amount 4 and displays the change amount 5 on the display section 6, which has a plurality of storage sections for storing cash by denomination. The drawer 7 has a sensor 8 that detects whether cash is taken in or taken out of each storage section of the drawer 7, and a denomination determination means 9 that determines the denomination of the deposit or withdrawal based on the output from the sensor 8. After the change amount 5 is displayed on the display unit 6, the determination means 9 compares the first determined denomination with the change amount 5, and if the denomination is larger than the change amount 5, an alarm is issued. It is equipped with a change alarm means 10 that issues a change alarm.

[Function] If the electronic cash register is equipped with such a method, the amount of change calculated by the change calculation by pressing the close key will be displayed on the display when the change is first put in or taken out of the drawer. An alarm is issued if the denomination is greater than the change amount. Therefore, if the cashier V attempts to put the cash received from the customer in the drawer before handing over the change, an alarm will be issued to alert the cashier.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. A receipt issuing port 13 is formed adjacent to. In addition, the sales amount 1 of the product entered from the keyboard 12 is displayed on the upper front part of the housing 11.
A cashier display 14 for displaying the total amount, etc. is provided, and a customer display 15 having the same configuration as the cashier display is attached to the upper surface of the housing 11. Furthermore, a second cashier's table is provided at the lower front of the housing 11 on which the cashier keeps the cash received from the customer until the cashier hands over the change, and a frame having a mouth-shaped recess on the lower surface of the housing 11 is provided. A drawer 17 consisting of a body 17a and a money case 17b that is detachably inserted into a recessed portion of the frame body 17a is installed.

The keyboard 12 includes a number key 18 for entering the sales amount, number of sales items, deposit amount from customers, etc. of the sales registration product, a department key 19 for entering the department in which each product is classified, and a sales registration key. A subtotal key 20 for displaying and printing the subtotal amount of the purchased products, a cash total key 21 functioning as a closing key for instructing closing of sales registration by cash settlement, and the like are arranged. In addition, on the keyboard 12, you can control the power on/off, as well as "registration" and "payment".
Mode switch 2 that instructs the central processing unit to execute various tasks as an electronic cash register such as "setting"
2 is provided.

FIG. 3 is a perspective view showing the overall structure of the money case 17b in the drawer 17, with a coin storage section 31 on the top surface.
and a banknote storage section 32 are formed. The coin storage section 31 includes, for example, a 1 yen coin storage section 31a from the right side in the figure;
5 yen coin storage section 31b, 10 yen coin storage section 31c, 50
Yen coin storage section 31d, 100 yen coin storage section 31e, 50
Divided by denomination such as 0 yen coin storage section 31f,
Similarly, the banknote storage section 32 includes, for example, a 1,000 yen banknote storage section 32a and a 5,000 yen banknote storage section 32b from the right side in the figure.

It is divided by denomination, such as a 10,000 yen bill storage section 32c. Further, each of the banknote storage sections 32a to 32G is provided with a flower pressing mechanism 33 for holding down banknotes. Furthermore, each storage section 31a to 31f and 32a to 32
C is provided with a denomination sensor 34 that detects whether cash is being deposited or withdrawn. As can be seen from the enlarged view of the 1 yen coin storage section 31a shown in FIG. 4, the denomination sensor 34 has an infrared light emitting element 34a and an infrared light receiving element 34b facing each other at approximately the upper center of both sides of each storage section. When Kirerasha takes in or takes out cash, it detects that the infrared rays from the light emitting element 34a are blocked by a finger or the like, thereby detecting whether cash is being taken in or taken out. The money case 17b is inserted into the recessed portion of the frame 17a by being pushed in the direction of the arrow in the figure. Then, a predetermined amount of cash is discharged in the opposite direction by the action of a drawer opening device (not shown), and in this state, cash can be taken in and taken out.

FIG. 5 is a block diagram showing the circuit configuration of the electronic reset register of this embodiment. In the same figure, reference numeral 41 denotes a central processing unit (CPIJ) as the main body of the control unit, which includes an arithmetic circuit, a memory control circuit, etc., and performs predetermined arithmetic processing based on various input data.
RO that stores fixed data such as programs through 2
M43 and the sales amount of registered products by department,
The RAM 44 is operated, which has various memories such as a sales aggregation memory for aggregating by transaction, etc., and a current total memory for calculating the total amount by adding up the sales amount of products sold to one customer. Additionally, a keyboard controller 45 inputs key signals from the keyboard 12 and converts them into signals that can be processed by the CPU 41, a display controller 46 drives and controls each display 14, 15, and a printer 47 prints on receipts and journals. A printer controller 48 for drive control, an output port 52 for outputting a buzzer on/off signal to a buzzer circuit 50 for sounding a buzzer 49 and an opening signal for a drawer opening device 51, and a command signal from the mode switch 22 are input. At the same time, an input port 54 for inputting a signal from a sensor circuit 53 for converting the output of the denomination sensor 34 into a signal that can be processed by the CPU 41 is connected to the CP, L via the path line 42.
Connected to I41.

When the CPU 41 receives a key from the keyboard 12, the CPU 41 determines the business mode selected by the mode switch 22, and executes key processing according to the business mode. For example, if the department key 19 is input after a number has been entered in the registration mode, it is determined that the product has been registered for sale, and the entered number is accumulated as the sales amount in the sales total memory of the RAM 44 by department, transaction, etc. Add to current total memory. In addition, the department and sales amount entered by the key are printed on the receipt and journal and displayed on each display 14 and 15.

Here, when the subtotal key 20 is input, the amount added in the current total memory is displayed on each display 14, 15 and printed on the receipt and journal. Then,
When the current total key 21 is input, key processing shown in FIG. 6 is executed. That is, after confirming that it is in the registration mode and that the product is being registered for sale, it is determined in ST1 whether or not a number has been entered immediately before. When the number is entered, the number data is the deposited amount from the customer, so a change operation is performed to subtract the total amount from the deposited amount, and the calculated amount of change is displayed on the display 14 and 15. Display. Also, the total amount, deposit amount, and change amount are printed on the receipt and journal. Thereafter, an opening signal is sent to the drawer opening device 51 to open the money case 17b and issue only a receipt from the receipt issuing port 13. In this state, ST2 waits for the input of a detection signal from the denomination sensor 34, and this signal input determines in which storage section of the money case 17b cash was deposited or withdrawn, in other words, it is determined whether cash was deposited or withdrawn first. Determine what the denomination of the cash is. Specifically, each storage section 31a to 3
The denominations corresponding to 1f and 32a to 32c are preset in the RAM 44 as a table, and based on the signal from the sensor circuit 53, the storage section in which the detection output of the denomination sensor 34 indicating the presence of insertion or removal is first generated is determined. Then, the above table is searched to determine the denomination corresponding to the storage unit that has been put in and taken out. Next, the denomination determined as ST3 and the display 14.1
Compare the amount of change displayed in 5. If the denomination is less than or equal to the change amount, the process proceeds to the next step. On the other hand, if the denomination is larger than the amount of change, the buzzer 49 is sounded.

On the other hand, if no number is entered in ST1, the total amount is used as the deposit amount to calculate change as in the conventional case, and the calculated change amount (0 yen) is displayed on the display 14.15. Also,
The total amount, deposited amount, and change amount are printed, the drawer is opened, only a receipt is issued, and the process proceeds to the next step.

In this embodiment configured in this way, when the cashier receives a payment from a customer that is more than the total amount, and enters the payment amount, so-called deposit amount, and inputs the current total key 21, the total amount is subtracted from the deposit amount. The amount of change is calculated and displayed on the display 14.15. Further, the total amount, deposited amount, and change amount are printed on the receipt, etc., and only the receipt is issued, and the drawer 17 is opened. In this state, when the cashier inserts a finger or the like into any storage section in the money case 17b, the denomination sensor 34 detects that cash has been taken in or taken out of that storage section, and the cash that has been taken in or taken out is detected by the denomination sensor 34. The denomination of is determined. Then, this denomination and the amount of change are compared, and if the denomination is greater than the amount of change, a buzzer 49 sounds.

Therefore, for example, if the total amount is 3,000 yen and the cash paid by the customer is a 5,000 yen bill, the cashier usually places the 5,000 yen bill on the cashier's table 16 and then presses the number key 1.
8, enter r5000J and operate the current total key 21. Then, the change amount will be r20 on display 14.15.
00J is displayed and the drawer 17 is opened, so the cashier takes out two thousand yen bills from the thousand yen bill storage section 32a of the money case 17b. At this time, the cashier's fingers or the like block the infrared rays from the thousand yen bill storage section 32a, so a detection output is generated from the denomination sensor 34, and from this detection output, the denomination r1000J of the deposit or withdrawal is determined. Therefore, in this case (change amount r2000J > denomination r1000J)
Therefore, the four buzzers do not sound. The cashier then hands the customer 2,000 yen in change and a receipt, and begins registering the next customer's sales.

However, the display 14.15 shows the amount of change as r 2 Q.
When OOJ is displayed and the drawer 17 is opened, the cashier table 16 is opened before the cashier takes out change.
When trying to put the above 5,000 yen bill in the drawer 17 and inserting a finger etc. into the 5,000 yen bill storage section 32b of the money case 17b to block the infrared rays, a detection output is generated from the denomination sensor 34,
From this detection output, the denomination r5000J of the withdrawal is determined, and in this case, (change amount r2000J ≦ denomination r50
00J), the buzzer 49 sounds. As a result, the cashier realizes that she made the mistake of trying to store the cash deposited by the customer in drawer 17 before handing over the change.

According to this embodiment, if the cashier makes the mistake of putting the cash received from the customer into the drawer 17 before handing over the change, the buzzer 49 will sound to alert the cashier, thereby preventing the occurrence of such a mistake. can be prevented from occurring. Therefore, the cashier always leaves the cash received from the customer on the cashier's table 16 until the change is handed over, so troubles caused by change can be suppressed. Furthermore, it is possible to prevent mistakes such as giving cash of a denomination greater than the amount of change as change.

Note that the present invention is not limited to the above embodiments. For example, in the embodiment described above, the denomination sensor 34 is made up of an infrared light emitting element 34a and an infrared light receiving element 34b, but since the trouble with change is mainly caused by banknotes, a microswitch is used in the flower holding mechanism. A denomination sensor may be constructed by linking the actuators. Further, in the embodiment described above, a case was shown in which an alarm is issued to the cashier by sounding the buzzer ~49, but the alarm may be issued by lighting or blinking an LED or the like. Further, in the embodiment described above, the yen was used as an example of the denomination, but it goes without saying that the present invention can also be applied to dollars, maltese, etc. It goes without saying that various other modifications can be made without departing from the spirit of the invention.

[Effects of the Invention] As detailed above, according to the present invention, it is possible to prevent the cashier from storing the cash deposited by the customer in the drawer before handing over the change, and to prevent troubles related to the change from occurring. It is possible to provide a compact electronic cash register.
