Abstract

PURPOSE:To allow processing which is interrupted after a power failure is detected to restart automatically after a power source recovers when the elapsed time from the occurrence of the power failure is shorter than a specific time. CONSTITUTION:If a power failure occurs after one of keys classified by transactions is operated, a power failure signal PD is inputted to a CPU and a counter TM starts counting operation. Then, the contents of an X, an Y, and a Z register are saved in a memory 11. When the PD is ceased, the counted value data (power failure time) of the TM is transferred to the X register and compared with the set time in a P register. When the power failure time is shorter than the set time in the P register, the saved data are returned to the registers to perform a display and a printing process. When the power failure time is longer than the set time, the processing is not performed even after recovery from the power failure and a specific key is operated to perform a display and a drawer opening processes.

Description

[Detailed Description of the Invention] QIT is an electronic cash register (ECR).
Concerning Kotobuki's computer equipment.

In the conventional ECR, if a power outage occurs during registration processing, the processing is interrupted, and after the power outage is restored, the processing is continued from the point of interruption. However, if a power outage occurs after a transaction key such as a cash key or rental key is operated and before the lower door is opened, if the door is opened during the process G after the power is restored. /! of theft in the absence of the operator! i2'1. Therefore, in the case of a power outage like this, I try not to open the drawer after the power is restored. In addition, displaying subtotals on the display while in the process of returning to the city is a sign that the operator is not in charge, and it is also undesirable from the standpoint of maintaining confidentiality. stop? ! No display is performed after recovery.

However, the above-mentioned process after returning from a stop is effective only after a relatively long stop where the operator leaves the CIR. In the case of I7+, even in the case of a short power outage where the operator is on standby, the door may not open or the display may not be displayed after the power is restored, so the operator may have to open the drawer U1. ■I had to perform release and display operations. Like this f! It is expected that key operations in special cases will not only be a burden on the operator, but also that it will take a considerable amount of time for the operator to know that the power has returned, and for the operator to operate the keys after knowing that the power has returned. This is not desirable for smooth operation.

This invention was made against the background of the above-mentioned circumstances, and its purpose is to measure the elapsed time since a power outage, and to measure the elapsed time by □7.6 hours. ,. ,
stop. Lol. The object of the present invention is to provide a computer device that automatically continues operations after recovery of the source.

Hereinafter, this invention will be specifically described based on an embodiment not shown in the drawings. FIG. 1 shows ECR blocks i and f according to this embodiment.
In the flink circuit diagram, a power source circuit l connected to an AC power source supplies a charging voltage to a secondary battery 2, and also connects an LSI (Large Scale Integrated Circuit) 3, an input section 4, a marking section 5, and a printing section. A driving voltage is supplied to the unit 6 and the drawer 7, respectively. The LSI 3 is driven by inputting the output voltage of the power supply circuit 1 or the secondary battery 2 through the corresponding backflow prevention diode 8.9, and has a c"pu (central processing Apparatus) 101 has a configuration including a total memory 11, a timer TM, etc.

-CPU 10 controls various operations, and includes an arithmetic logic circuit (not shown), arithmetic and arithmetic auxiliary X,
In addition to the Y and Z registers, there are also P and Q registers in which arbitrary time data inputted by key operations from the input section 4 are set. Also, CPU1
0 is mutually connected to the total memory 11 and exchanges data. In this case, the total memory 11 stores the total number of sales, amount, etc. by department, separately, etc.
It is composed of RAM (Random Access Memory) and performs data write and read operations under the control of CP Lr 3. Further, the CPUI0 reads the contents of the timer TM and outputs a clear signal CL to the timer T to clear the contents. This counter TM counts the clock signal t of a predetermined frequency inputted via the AND gate 12.
It is opened by the gate IJ close signal outputted from the CPU10 by being input to the gate IJ, and outputs the p-check signal t to the counter TM. Therefore, the counter TM
is a counter that counts the elapsed time since the power outage signal PD was input from the CPU I O, that is, the power outage time.

The input unit 4 has numeric keys, department keys, keys for credit sales, cash sales, etc., and in this embodiment, the CPU 1
The CPU 10 has a predetermined key for inputting time data set in the P register and the Q register in the CPU10.
In response to the timing signal KP from the control key, the input signal is output to the input key data INt-CPTJIO corresponding to the operation key. In addition, the display unit 5 digitally displays the display data from CPTJIO, the printing unit 6 prints the print data from CPU10 on recording paper, and the drawer 7 receives the drawer release signal from CPt710 through its internal solenoid (Fig. (not shown) is released by applying a voltage to 0.Next, the operation of the above embodiment will be explained. First, before executing the normal registration process, input the CPU information from the input section 4 in advance.
Arbitrary time data is set in the P register and Q register in 0. When the registration process is started and the transaction-specific key is operated, the operation according to the flow shown in FIG. 2 is executed. That is, first, in step S1,
7j] Transaction-specific arithmetic processing such as cash sales, credit sales, etc. corresponding to the different keys is executed, and the input data is counted in the transaction-specific total data storage area in the total memory 11.

When this separate arithmetic processing is completed, it is checked in the next step S2 whether or not a power outage signal PD is input from the power supply circuit 1.

Assuming that there is no power outage in the AC power supply, there is no power outage and no signal PD is input, and in this case, the process advances to step S3 to perform display processing, and then to step S4 to perform printing processing. Since this display and printing process takes a relatively long time, in the next step S, the same process as the above step S, in which it is determined whether or not the power outage signal PD is input, is repeatedly executed. As a result, if a power outage has not occurred, the process proceeds to step S6, where the contents of the counter TM are cleared, and then, at the next step S7, the game 112 is opened and the counter TM starts to perform a number of operations. Then, in the next steps S8 to Sho, the drawer 7 is moved to the predetermined same amount 11WJfiL according to the time data set in the Q register in advance.
This is the process of That is, in step Sg, the solenoid (not shown) in the drawer 7 is turned on, and
Next step S.

Transfers the count value data of 1 to the phantom counter T to the X register, and checks whether the contents of this X register are larger than the contents of the Q register in the next step S1n'T:''.
As a result, the contents of the X register are within the contents of the Q register,
In other words, it drives the Droasure Maid.

The time being used must be within the time set in the Q register.

For example, the process returns to step S8, and steps 88 to SIO are repeated at a time exceeding the set time of the Q register. Then, when the drawer maid is driven for the above set time, the drawer 7 is released by U11.

The above operation is performed when a power outage does not occur.Next, the operation when a power outage occurs will be explained.

If a power outage occurs after the transaction-specific key is operated, it is determined that the power outage signal PD has been input in step S or step S, and steps 811 to 811 are performed from steps S, , and S, respectively.
Proceed to execution of step 816. First, the contents of the counter TM are cleared in step S1□, and then the Wl number operation of the counter TM is started in the first step S12. And display,
Step SI4 for storing print data, etc. performs the same processing as steps S1 and S5 above, but in this case, it is in a standby state until the input of the power outage signal PD becomes urgent. When the power failure signal PD is no longer inputted, step S1! Proceeding to step I, the count value data of the counter TM is transferred to the X register. Therefore, the contents of the 1X register are the elapsed time (power outage time) from when the power outage signal PD is input until it disappears. Next step S, 6 is X
If the content of the register is less than or equal to the set time of the P register between the P registers, the process advances to the next step S17, and X,
After restoring the display 1 print data to the Y and z registers,
Proceeding to step S3, a display process and a print process are executed, and thereafter, if a power failure does not occur, the drawer opening process described above is executed. That is, if the power outage time is less than or equal to the set time, the process that was interrupted when the power outage was detected is automatically continued after the power outage ends. On the other hand, as a result of the determination in steps S and 6, if the power outage time in the X register exceeds the set time in the P register, the processing that was interrupted when the power outage was detected will not be executed even if the power outage is no longer present.

In this case, display processing, drawer opening processing, etc. are performed by operating a specific key after the power outage is over.

In this way, if you set arbitrary time data in the P register in advance, for example, in the case of a momentary power outage of 4 degrees,
Processing that was interrupted when a power outage was detected is automatically continued after the power outage is removed.

Although the above embodiment was applied to <1EC·R, it may be applied to other devices in total.

Further, in the above embodiment, an arbitrary time data can be set in the P register, but this time data may be fixedly stored by the manufacturer.

As described in detail above, this invention measures the elapsed time B1 after a power outage, and if this elapsed time is less than a predetermined value, the process that was interrupted after the power outage was detected is stopped when the power outage becomes hot. Since the system was set to automatically continue from the start, the most appropriate process can be performed after the power outage is restored, depending on the length of the power outage. Especially when the power outage is short, key operations are not required to open the drawer or display the display, so there is no need to place a burden on the operator, and there is no need to immediately open the drawer 5 when the power is restored. The process continues automatically.
