DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an electronic cash register having both the function of issuing tickets such as meal tickets and the function of registering money.

(b) Conventional technology Recently, there has been a demand for cash registers that have both the functions of issuing meal tickets and registering money in restaurants such as cafeterias, and cash registers that can issue meal tickets have already been commercialized. In the conventional method, for example, as shown in Japanese Patent Application Laid-Open No. 57-203168, one meal ticket is issued in response to the operation of a registration key for each item.

By the way, at a restaurant, there are cases where a large number of people order a large number of the same products. If the number of key operations is large, key operations are complicated and the operability is poor, such as the need to count the number of key operations.

(c) Problems to be solved by the invention The present invention has been made to solve the above-mentioned problems. Even when multiple items of the same product are ordered, meal tickets for the number of orders can be issued with a simple key operation. The present invention provides an electronic cash register that can be used to store cash.

(d) Means for Solving the Problems The present invention has a numeric keypad for inputting the number of products and unit price, a multiplication key, and stores the number of products and unit price in response to operations on the numeric keypad and the multiplication key. a unit number storage unit and a unit price storage unit, a department key provided for each product department, a product storage unit that stores the product of the number of items and unit price in response to the operation of the department key, and a printer that prints the ticket surface. , a ticket cutting device, a setting means for setting the printing state and cutting state by the printer and the ticket cutting device, and a control means for controlling each of these devices.

(E) Effect Since the present invention is configured as described above, when multiple items of the same product are ordered, when a key operation is performed to register the multiplication of the number of items x unit price and the department key is operated, it is detected that the multiplication registration has been performed. The control means registers the contents of the product storage section and, based on the printing conditions set in the setting means, stores tickets with at least the unit price stored in the unit price storage section printed thereon in the number storage section. Since the stored number of food tickets can be printed and then cut by the cutting device based on the cutting conditions set in the setting means, the key operation becomes easy when issuing a plurality of the same meal tickets.

It consists of CT and total area TL where the sales amount is added up. These calculation and totalization memories are all designated in advance at addresses within the RAMs 16d and 16e, and their storage contents are changed by address instructions from the CPU 15 to execute various functions.

FIG. 5 shows a deep switch 27 for setting the printing state and cutting state of the meal ticket.
When 7a is ON, it becomes the meal ticket issuing mode, and when it is OFF, the mode is switched so that it becomes a normal cash register that does not issue meal tickets. The switch 27b is
When ON, the switch 27c issues a meal ticket with a receipt as shown in Figures 10 and 11, and when OFF, the switch 27c switches to issue a meal ticket without a receipt as shown in Figures 12 to 15. When the switch 27c is ON, it issues a meal ticket with a receipt. The cutting mode is switched to make perforations and cut, and to turn off the cutting mode to cut one sheet at a time. In addition, the switch 27d is ON, and the switch 27d is set to 1 for each item as shown in Figure 14.
A double meal ticket is issued, and in OFF mode, the system switches to issue a double meal ticket with the same items printed above and below, as shown in Figure 15. Furthermore, when the switch 27e is ON, it issues a food ticket with a store name stamp printed on it as shown in FIG. 10, and when it is OFF, it issues a food ticket without a store name stamp as shown in FIGS. 12 and 13.

Next, the operation of the present invention having such a configuration will be explained based on the flowcharts of FIGS. 8 and 9 and with reference to FIGS. 10 to 15.

As a specific example, a case will be described in which a person eats and drinks five bottles of beer at a unit price of 350 yen at a cafeteria, as shown in the key operation shown in FIG.

First, the mode control lock 9 is rotated to the registration (Reg) position, and then the number "5" is input using the numeric keypad 2. The input data is transferred to the A register 34 in step (a), and "1" is stored in the flag NF 42a, thereby setting the flag. Next, when the multiplication key "@/For" 12d is operated, the process moves to step (b), where the number data "5" stored in the A register 34 is transferred to the B register 35, and "1" is set in the flag AFF 42b. " by storing and setting the flag NF42a and storing "0" in the flag NF42a.
is being reset. Next, use the numeric keypad 10 to enter the unit price of 350 yen as "3", "5", and "0", and in the same way as above, the input data "350" is stored in the A register 34 in step (a).
Also, flag NF42a is set. Next, when the department key "DEPT4", which is the beer department, is operated, the process moves to step (c), where flag AFF4 is first pressed.
2b is set.
Now use the multiplication key "@/For" 12d to flag
Since AFF42b is set, the multiplication step d is entered and the A register 34 stores the unit price.
The B register 35 stores the data and number of
, and the result of the multiplication is stored in the C register 36. Next, the value of the B register 35 is added and accumulated to the quantity area CT of the department memory 46, and the value of the C register 36 is added and accumulated to the total area TL. Therefore, in this state, the quantity area CT of the department memory 46 has "5", and the total area TL has 5×
"1750", where 350 = 1750 yen, is memorized. Further, the flag DPF 42c is set, and the R counter 38 for counting the number of issued tickets is set to "00".

Next, we move on to the routine shown in FIG. 9 for executing printing. The printing format can be selected as shown in FIGS. 10 to 15 depending on the state of the dip switch 27, and will be explained in order.

First, as shown in FIG. 10, a case will be described in which a receipt 47 is followed by a number of meal tickets 48 connected at perforations and issued. At this time, the depth switch 27
a to 27e are all ON as shown in column A of Figure 7.
The state is set. Therefore, the CPU 15 transfers the print data of the receipt section 47 from the storage section to the P register 37 in accordance with the printing order. When the data is transferred to the P register 37, printing is automatically performed by the dot printer 22 by the print controller 19. In this case, the store name was already stamped on the previous receipt when it was issued. The printed contents are date (i), time (b), quantity (c), unit price code (d),
These include unit price, department and item name, total, machine number, number of customers, person in charge, and serial number of meal ticket issue. When printing is completed, the switch 27c is ON, so after partial cutting and perforations are made, "0" is stored in the flag WF 42d, and the R counter 38 for counting the number of issued tickets is incremented by 1.
Next, in order to issue the first meal ticket, the CPU 15 again writes the date (i), time (b), department and product name, unit price code (d), unit price (e), aircraft number (i), number of customers (re), and person in charge from the storage unit to the P register 37. The first meal ticket 48 is then printed.
Next, since switches 27d and 27c are ON,
After performing a partial cut to create a perforation, the value in the B register 35 is subtracted by 1. However, since only one food ticket has been issued and the value of the B register 35 is not "0", the process returns to step (i) again and stores "0" in the flag WF42d, and the R counter 3
After adding 1 to 8 to make ``2'', a second meal ticket is issued in the same manner as described above. At this time, the meal ticket issuing serial number is printed as "02" based on the R counter 38. In this way, meal tickets are issued until the value of the B register 35 becomes "0", and a total of five meal tickets are issued. When the value of the B register 35 becomes "0", the flags NF42a and AFF42b are set to "0", and then the switch 27b is turned ON.
Therefore, cutting is performed. Therefore, as shown in FIG. 10, five meal tickets 48 are issued in succession following the receipt 47. Furthermore, switch 27e is turned on.
Therefore, the stamp is activated to print the store name for the next receipt and return to the starting state.

When another product is subsequently input, meal tickets for the number of items ordered are issued in the form shown in FIG. 10 in the same manner as described above. If the number of items ordered is one, the department key 11 is operated after entering the amount.
Since the multiplication key 12d is not operated, the flag AFF
Since "1" is not stored in 42b, proceed to step (e), add 1 to the quantity area CT of the total memory 43, and add 1 to the amount area TL of the A register 34.
After adding the preset amount, set ``00'' in the R counter 38 and ``1'' in the B register 35, and then proceed to step (i) of issuing a meal ticket. It is issued with a restaurant name printed on it and a meal ticket attached to it. In this way, meal tickets are issued in the form shown in FIG. 10 depending on the number of products ordered.

And finally, after all orders are completed, total key 12a
When is operated, the routine proceeds to routine f for normal total processing, processes the total memory 43, issues a receipt with the total amount printed, prints the store name for the next receipt with a stamp, and returns to the starting state. This completes the registration and meal ticket issuing operations for one customer.

Next, if only the switch 27c is set to OFF as shown in column B of FIG. 7, the paper is cut off each time printing is completed, so that it is possible to cut and issue one sheet at a time as shown in FIG. 11. Also, Figure 7C
Turn off switches 27b and 27e as shown in the column.
If set to , the store name will not be printed using a stamp, and the receipt printing step h will be skipped depending on whether the switch 27b is ON or not, so only the meal tickets will be connected at the perforations, as shown in Figure 12. It will be issued in the same condition. Furthermore, from this state, switch 27c is turned OFF as shown in column D of Figure 7.
When set to , only the meal tickets are cut one by one and issued as shown in FIG.

Next, if you want to issue each meal ticket with the store name stamped on it as shown in Figure 14, set switches 27b and 27c to OFF and the rest to ON as shown in column E of Figure 7. It can be issued by In other words, after the store name stamp is printed and the food ticket data is printed on one sheet, it is completely cut off.
Subsequently, since the switch 27b is OFF, the process proceeds to step k for printing the store name for the next meal ticket, and after printing the store name, the second meal ticket is printed and issued.

Next, as shown in Figure 15, if you want to print the same items as the food ticket following the store name and use it as a stub, press the switch 27 as shown in the bottom column of Figure 7.
It can be issued by setting a and 27e to ON and the rest to OFF. That is, after printing the store name and then printing the same content as the meal ticket in step (i), since the switch 27d is OFF, the process proceeds to step (l) and sets the flag WF42d to "1". After performing partial cutting to create perforations, return to step (i) again to print the meal ticket. Printing end flag WF42
Since d is not "0", proceed to step (j) and completely cut. In this way, a ticket as shown in FIG. 15 is issued. After the store name for the next ticket is printed with a stamp, return to step (i), set the flag WF42d to "0", and set the R counter 3.
By adding 1 to 8, a ticket with the ticket issue serial number "02" is issued as shown in FIG. Similarly, five tickets are automatically issued until the B register 35 becomes "0".

In this way, the deep switches 27a to 27
By switching e, at least six types of ticket issuing states can be obtained, so that an appropriate ticket issuing state can be selected depending on the actual situation of the restaurant such as a cafeteria or restaurant.

If the switch 27a is set to OFF, the ticket issuing function is stopped, and after the registration process, the process proceeds to step (g) to issue a normal receipt and function as a cash register.

(G) Effects of the Invention As described above, when multiple items of the same product are ordered, the electronic cash register of the present invention can issue meal tickets for the number of orders with a simple key operation for multiplication registration. In addition, since each meal ticket is numbered consecutively, it is easy to check the number of tickets.Furthermore, you can choose whether to cut the ticket separately or leave a part of the ticket with a perforation etc., making it easy to check the number of tickets. This has the effect of issuing matching meal tickets.
