Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic cash register that can take measures against power outages.

[Prior Art] Generally, an electronic cash register consists of a CPLI that constitutes the main body of the control unit, a ROM that is a non-volatile memory that stores program data, a RAM that is a volatile memory that has a memory for data registration, etc., a keyboard, and a display. , printer, drawer, etc. Conventionally, in such electronic cash registers, when a power outage occurs, power backup is provided to the RAM, but the power to the CPU, keyboard, display, printer, drawer, etc. is cut off and they cannot operate at all. For this reason, registration work could not be completed at all during power outages.

[Problems to be Solved by the Invention] As described above, in the conventional electronic cash register, when a power outage occurs, registration work cannot be performed at all.

For this reason, it is best to prepare a power supply that can back up all circuits in the event of a power outage, but printers and drawer opening devices require a large amount of power, so it is necessary to use a backup power supply with a fairly large capacity, and installation is difficult. There are problems with space and cost.

Therefore, the invention of Application No. 1 backs up power only to other circuits, excluding those that require large amounts of power such as printers and drawer opening devices, so that product sales data can be maintained even if a power outage occurs. The present invention aims to provide an electronic cash register that allows registration work and prevents a decrease in work efficiency.

A second aspect of the invention is to provide an electronic cash register that can print out product sales data that was registered during a power outage when the power outage is restored, and that does not pose a risk of hindrance to registration operations.

[Means for Solving the Problems] The first invention performs data processing based on an input operation on an input unit, registers product sales data in a registration memory having a backup power supply, displays it on a display, and displays the product sales data on a display. In an electronic cash register that prints out a printout, issues a receipt by closing the registration at the input section, and also drives the drawer opening device, the input section, data processing section, registration memory, display, printer, and drawer opening device are connected to each other. The system is equipped with a main power supply for supplying current, and a power supply for power outage that is activated when the main power supply fails and supplies power to at least other circuits other than the printer and the drawer opening device.

A second invention further provides a detailed memory for separately storing product sales data that is registered in the registration memory while the power outage cloth source is operating, and a printer that operates when the main power supply returns to the power outage. A power failure recovery printing control means is provided for driving and printing out the contents stored in the detail memory.

[Function] In the first invention having such a configuration, when a power outage occurs and the power supply for power outage operates, at least the other circuit parts except the printer and the drawer opening device are energized. The input section, data processing section, registration memory, and display will be able to operate. Therefore, it is possible to perform data processing based on input operations on the input unit and register product sales data in the registration memory.

Further, in the second invention, the product sales data registered in the registration memory at the time of power outage is further stored in the detail memory,
When the main power is restored, the contents stored in the detailed memory are printed out by the printer. Therefore, a receipt can be issued.

A total key 6d, a detail key 6e, a changeover switch 19 between normal times and power outages, and the like are provided.

As shown in FIG. 3, the detailed memory provided in the RAM 3 includes a customer number memory 3a, a department code, a flag,
A plurality of product sales data storage memories 3b each having an area for registration details, an overflow memory 3c for adding and storing data to be registered after this memory 3b becomes full, and a total amount memory 3d for storing the total amount of the customer. It is made up of.

As shown in FIG. 4, the power supply for power outage 17 is provided with a battery 20, and the collector of an NPN transistor 21 is connected to the positive terminal of the battery 20, and the base of the transistor 21 is connected to the negative terminal of the battery 20 via a Zener diode 22. connected. A capacitor 23 is connected in parallel to the Zener diode 22. Further, a series circuit of a resistor 24 and a normal side contact 19a of the changeover switch 19 is connected to the Zener diode 22 in parallel.

The power failure side contact 1 of the changeover switch 19 is connected between the collector and base of the transistor 21 via the resistor 24.
9b is connected.

Then, +5V is output from the emitter of the transistor 21 via the diode 18, and a power failure mode signal S is also output.

The CPU 1 is set to perform registration control as shown in FIG. That is, it is checked whether the power outage mode signal S is output from the power outage power source 17, and the signal S is output.
If it is not output, then it is checked whether or not there is an input to the detail key 6e, and if there is no input, normal memory processing is performed. When a department registration operation is performed on the keyboard 6 by entering an amount using the number keys 68 and selecting the department key 6b, product sales data is registered in the registration memory of the RAM 3 by department. Then, the registered product sales data is displayed on the display 8 and printed out on a receipt and a journal using the printer 14.

The above normal memory processing, display, and printing are repeated while department registration is being performed using the keyboard 6. Finally, when the deposit/total key 6d is operated, the drawer opening device 13 is driven and the drawer is opened. 12 is opened, and the printer 14 prints out the customer's total and issues a receipt.

In addition, the power outage mode signal S from the power outage power supply 17 is set to f[[i
Product sales data input from the keyboard 6 is registered by department in the registration memory of the RAM 3 and displayed on the display 8. Furthermore, if the product sales data storage memory 3b of the detail memory is not full, registration is also made to that detail memory. That is, the customer number is registered, and then the product sales data is sequentially stored in the memory 3b, and the total amount at that time is sequentially stored in the total amount memory 3d.

Note that the printer 14 is not controlled at this time.

When the product sales data storage memory 3b becomes full during registration in the detail memory, the product sales data is sequentially added to the overflow memory 3c and stored. Finally, when the deposit/account key 6d is operated, the customer number stored in the customer number memory 3a is displayed on the display 8.

When the power outage mode signal S is no longer output from the power supply 17 for power outage while the product sales data is stored in the detail memory, and the detail key 6e is operated on the keyboard 6, the product sales data is stored in the detail memory. Product sales data is sequentially printed out by the printer 14, and a receipt is issued when the printing is completed.

In this embodiment having such a configuration, when product sales data is input from the keyboard 6 while the power supply circuit 16 is operating normally, departmental registration is performed in the registration memory of the RAM 3.

Note that the product sales data is input using the number keys 6a and the department keys 6b. The product sales data registered in the department is displayed on the display 8 and printed out on the printer 14.

After this department registration operation has been performed for all the products purchased by the customer, the customer finally operates the deposit/total key 6d to complete the registration. This drives the drawer opening device 13 to open the drawer 12, and the printer 14 issues a receipt.

Further, when a power outage occurs in the power supply circuit 16, the changeover switch 19 is switched to the power outage side. As a result, the transistor 21 turns on, and the diode 18 is connected from the power supply 17 for power outage.
+5V is supplied to the CPU 1, ROM 2, RAM 3, keyboard controller 5, keyboard 6, display controller 7, display 8, and each 110 port 9.10 through
is supplied to

Thereby, the CPU 1 registers the product sales data input from the keyboard 6 in the registration memory of the RAM 3 by department and displays it on the display 8. It is also stored individually in the detailed memory of RAM3.

When the registration is completed using the deposit/total key 6d, the customer number in the customer number memory 3a is displayed on the display.

In this state, when the power supply circuit 16 is restored from the power outage, the selector switch 19 is returned to the normal side and the details key 6e is operated 1.
The product sales data and the total amount stored in the detail memory are sequentially retrieved and printed on a receipt by the printer 14, thereby issuing a receipt.

In this way, even if a power outage occurs in the power supply circuit 16, the power supply 17 for power outage enables power to be supplied to other circuits except for the drawer opening device 13, printer 14, and printer drive circuit 15. Registration and display will be possible. Therefore, registration of product sales data can be continued even during a power outage, and work efficiency can be prevented from decreasing.

In addition, the power supply 17 for power outage is CPU1, RO with low power consumption.
It is sufficient to energize M2, RAM 3, keyboard controller 5, keyboard 6, display controller 7, display 8, and each I10 board 9, 10, and a large capacity is not required.

In other words, the capacity of power supply 17 for power outage can be reduced.

In addition, the product sales data registered at the time of a power outage is stored sequentially in the detailed memory, and when the power supply circuit 16 recovers from the power outage, the product sales data stored in the detailed memory can be printed out using the printer 14 to issue a receipt. Even if there is a receipt, it will be possible to give the receipt to the customer, and there will be no hindrance to the registration process. In addition, there is a large amount of product sales data to be registered during a power outage, and when the product sales data storage memory 3b of the detail memory becomes full, the overflowing sales data will be stored all at once in the overflow memory 3C. Although the data will be unknown, it will not be inconsistent with the total amount.

[Effects of the Invention] As detailed above, according to the invention of Application 1, power is backed up only for other circuits excluding those that require large amounts of power, such as printers and drawer opening devices, in the event of a power outage. As a result, it is possible to provide an electronic cash register that allows product sales data to be registered even in the event of a power outage, thereby preventing a decrease in work efficiency.

Further, according to the second invention, it is possible to provide an electronic cash register that can print out product sales data registered during a power outage when the power outage is restored, and that does not pose a risk of hindering registration operations.
