Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to an electronic cash register, and in particular, in the event of a power outage during registration, receipts can be fed in order to know which products have been registered. This invention relates to an electronic cash register.

[Problems to be solved by conventional technology and invention]

Conventional electronic cash registers have a power outage detection memory or registration memory to determine whether they were in the middle of business or registration when a power outage occurred. It detects the power failure detection memory, displays all F on the display, and generates an error sound. Therefore, when the power is turned on, it is possible to know that the registration process is still in progress due to a power outage during registration, but it is not possible to confirm which products have been registered. In other words, information about registered products is printed on the receipt, but the part where information about the last registered product was printed (the last printed line) remains inside the printer and cannot be seen. , it was not possible to determine which products were registered based on the printed contents of the receipt. Therefore, if you operate the clear key to reset the power failure detection memory to release the error state and then continue the registration operation, registration may be missed.
Or, it often happens that multiple registrations occur.
It will take time and effort to get things back to normal.
The flaw was that the registration process was particularly congested during busy periods, which had a negative impact on sales.

The present invention makes it possible to easily check which products have been registered by making the last printed line of the receipt visible when the power is turned on after a power outage occurs during registration. The object of the present invention is to provide an electronic cash register that allows registration operations to be continued without causing repeated registrations or registration omissions.

[Means for solving problems]

Therefore, this invention has a departmental memory in which the cumulative price of the purchased product is registered based on the input of registration information corresponding to the purchased product, and a cumulative purchase amount that is printed based on the product price and closing input from the keyboard. A printer that prints on the receipt and feeds the receipt according to commands, a power failure detection memory that is set at the start of work and reset at the end of work, and a memory that is set by inputting registered information and is used for tightening operations. A clear function that resets the power failure detection memory by canceling the error state that is generated based on the set state of the registration memory, the receipt feed key that causes the receipt feed to be performed with the printer, and the power failure detection memory when the power is turned on. In the electronic cash register having a key, when the power is turned on, the registering memory determining means determines the set state of the registering memory, and the registering memory determining means determines the set state of the registering memory based on the registering memory determining means. a receipt feed command means for setting the receipt feed memory and outputting a receipt feed signal for a specific line to the printer; a receipt feed memory determining means for determining the receipt feed memory; and a receipt feed memory determining means. Only the processing of the receipt feed key is permitted based on the determination of the setting of the means, and upon input of the receipt feed key, a receipt backward feed signal for the specific line is output to the printer, and the receipt feed memory is reset. It is an object of the present invention to provide an electronic cash register characterized in that it is equipped with a receipt backward feed command means.

[Operation] With this configuration, if a power outage occurs during registration, the receipt will be automatically fed when the power is turned on, and the last part of the receipt where information about the registered product is printed will be fed to the printer. It is possible to visually confirm the information regarding the last registered product that is externally derived. Also, in this state, only the receipt feed key is valid, so operate the receipt feed key to reverse feed the receipt to set the state at the time of a power outage, and then operate the clear key to clear the error state. This means that you will not be able to cancel the registration, and you will not be able to continue the registration while feeding the receipt.

A "current/total" key is provided. Further, above the number key 2a, there are paper feed keys 8 such as a receipt stop/issue switch, a push-button type receipt feed switch 8b, a record feed switch 8c, etc., and a button 8 used for setting the date and register number. "Date/Register No." key 8a is provided. In addition, the upper front of the keyboard 2 has positions for □-, lock, registration, inspection, payment, and setting. control key 9
A lock-type person-in-charge key 10, 10 is also provided to identify the person in charge.

Next, according to FIG. 3, in this example
The circuit configuration of ECR1 will be explained. 11 is a central processing unit (hereinafter abbreviated as CPU), 12 is a departmental memory,
RAM with transaction-specific memory and responsible person memory, etc.
13 is a RAM having a display buffer memory, a print buffer memory, a number buffer memory, etc., and 14 is a ROM in which various business processing programs are written in advance. Note that the RAM 12 is a memory having a protection function to prevent data from being erased due to a voltage drop during a power outage. and control key 9
When the paper feed key 8 or the like is operated, the content of the operation is transmitted to the CPU 11 via the switch control circuit 15.
It has come to be transmitted to Also, keyboard (2)
, when various keys are operated, the operation contents are transmitted via the keyboard interface 16.
The information is transmitted to the CPU 11. CPU1
1 is based on the operation contents of the control key 9 and the operation contents of various keys on the keyboard 2.
A predetermined program is called from the ROM 14, the data input control circuit 17 is driven based on the program, and data input from the keyboard 2 is written into the RAM 12.
Of course, the data entered from keyboard 2 is
It is temporarily stored in each buffer memory in the RAM 13. Further, the CPU 11 sends data to the display 3 via the display interface 19 by driving the data input control circuit 18.
and print interface 2.
0 to the printer 21. Further, the power supply circuit 22 supplies operating voltage to each circuit of the ECR 1, and the power failure detection circuit 22a detects a power failure in the power supply circuit 22.
When the RAM 12 detects a power outage, a battery 23 for backing up the RAM 12 replaces the power supply circuit 22 and supplies operating voltage.

Next, a memory area according to the present invention will be explained. As shown in the memory map in Figure 4, RAM1
2, a flag memory area is set which is composed of a PF memory area 12a, an RFF memory area 12b, and a UR memory area 12c.
The PF memory area 12a contains a power failure detection flag,
A receipt feed flag is set in the RFF memory area 12b, and a registration flag is set in the UR memory area 12c. They are set by writing "1" and by clearing them to "0". Ru.

Since the present invention relates to the above-described configuration, receipts can be fed by the following means. Regarding power outage detection, power outage detection flag PF
A 12a memory is provided, and this flag is set in the memory when a product is registered or when printing starts, and is reset when the "Current/Total" key is closed or when printing is finished. do. Further, a registration flag is set in the registration memory area 12c by inputting registration information, and is reset when the flag is closed by operating the current key. Note that each memory area 12a, 12
b, 12c, even if a power outage occurs, as mentioned above,
Since the RAM 24 is backed up by the battery 23, it maintains the set state. That is, the PF memory area 12a is a power outage detection memory for detecting that a power outage occurred during a business, and the UR memory area 12c is a registration memory that stores information that a business in progress is being registered.

Now, to explain the operation according to the flowchart shown in FIG. 5, when the power is turned on after the power outage is restored, the power outage detection flag PF12a is checked.
If it is in the reset state, the display 3 will show the usual "0", but if it is in the set state,
The display 3 displays all "F" and a buzzer sound is output. At the same time, it is checked whether the registration flag UR12c is set, and if it is set, the receipt is fed by a specific line. In this embodiment, the specific row feed amount is set to 4 pulses. At this time, the receipt feed flag
RFF12b is set. The operator can check the receipt and see how much of the registration data was registered before the power outage. That is, the RFF memory area 12b is a receipt feed memory that stores that the receipt was fed forward by a specific line after the power was restored.

Note that since the power failure detection flag PF12a is set even during printing as described above, a phenomenon in which the receipt is fed back occurs even if there is no power failure during registration, so this embodiment is more effective as a means to prevent this. As a preferable example, registering flag UR
12c was provided. In other words, after the power is restored and all F is displayed on the display 3, the registration flag is
It is configured such that the receipt feed pulse is output by checking whether or not it is set in the UR12c, and only when the registration flag is set in the UR12c.

Next, the receipt backward feed when the receipt feed key is operated according to the flowchart shown in FIG. 7 will be described. In addition to the clear "C" key, there are keys that can be pressed after the power is restored, such as the receipt feed key "RF" key 2d or "JF" key 2e to restore the receipt. In this case, the key is locked so that the next key operation is not possible unless the receipt feed is returned. When it is necessary to apply this lock, the receipt feed flag RFF12b is set by the receipt feed after F is displayed on the display 3.
is set and until it is reset in response to the operation of the "RF" key 2d. That is, other key inputs are prohibited while the receipt feed flag RFF12b is set.

In addition, Flow 2 of the flowchart shown in FIG.
Receipt Feed Flag RFF as shown in 4
When RFF 12b is reset, it functions as a normal receipt feed, but when RFF 12b is set, four receipt backward feed pulses are output, and RFF 12b is reset. By resetting this RFF 12b, it becomes possible to input a clear key to cancel the error state.

〔Effect of the invention〕

As described above, with this invention, even if a power outage occurs during product registration, the receipt will be fed immediately after the power is restored, and it will be possible to visually determine how much of the key-input data has been registered, thereby preventing duplicate registration or registration. It is now possible to continue registration correctly without missing out. Therefore, even if there is a power outage during a busy period of customers, there will be no disruption.
After recovery, efficient registration operations can be carried out immediately without any hindrance.
