In particular, by using a mark detection sensor, at the same time, the normal state of transfer of the recording medium, the operating state of the driving device, the connection state of the connector, and the remaining amount of the recording paper for auditing are simultaneously used. The present invention relates to an apparatus for checking the remaining amount of paper and operating conditions of an ATM.

In general, an existing cash dispenser manages cash and check payment boxes separately, that is, cash is put in cash boxes and checks are put in check boxes and withdrawn.

The conventional automatic teller machine of this type includes a bill separator including a bill charger for acquiring cash and checks, a DC motor for separating bills for picking up the bills charged into the bill, and a bill separator. It consists of a banknote conveyance part for conveying the picked-up banknote.

Referring to the operation of the conventional automatic teller machine configured as described above are as follows.

First, the bill charging unit has a separate box for charging cash and check, and the cash or check is picked up one by one by a DC motor for separating bills in the bill separating unit, and the withdrawn bill is transferred to the bill transferring unit. Is transferred to the desired position.

Here, the cash charging box or the check charging box is the same size, and each can charge about 1500 to 3000 sheets.

In this case, an additional inspection apparatus is additionally provided to determine the operation state of the recording paper, the motor, and the like. Further, an additional apparatus is additionally determined to determine the JAM.

Therefore, such a conventional automatic teller machine has to include a separate inspection device to determine the transfer state of the recording sheet or the operation state of the JAM and the motor, thus causing a problem of cost increase and complexity of the device.

Therefore, the present invention is to solve the above problems of the conventional automatic teller machine, an object of the present invention by using the mark detection sensor for the normal transfer of the recording medium and the operating state of the drive device and the connection state of the connector and audit An object of the present invention is to provide an apparatus for checking the remaining amount of paper and the operating state of an automatic teller machine that enables the remaining amount of paper to be recorded at the same time.

Technical means for achieving the object of the present invention comprises a load sensor for determining the presence or absence of a recording sheet; A mark sensor for inspecting a mark on the recording sheet; A printer for printing the data on the recording sheet; Comparison means for comparing the mark inspection value of the mark sensor with a reference value and outputting a result value; And a central processing unit for storing the output mark value of the comparing means in a memory and judging the remaining amount of the recording sheet and the transfer state based on the mark value.

Hereinafter, described in detail with reference to the accompanying drawings of the present invention.

1 is a schematic block diagram of a recording paper remaining amount and an operating state inspection apparatus of an automatic teller machine according to the present invention.

As shown, a load sensor 10 for determining the presence or absence of a recording paper (journal), a mark sensor 20 for inspecting a mark on the recording paper, and a printer 30 for printing the data on the recording paper. ), A recording paper 40 on which data is recorded, and a journal reel 50 for winding and storing the printed recording paper.

2 is a circuit diagram of the recording paper remaining amount and operation state of the automatic teller machine according to the present invention.

As shown, the comparator 60 compares the mark value detected by the mark sensor 20 with the reference value and outputs the result value, and stores the mark value output from the comparator 60 in the memory 80. The central processing unit 70 determines the remaining amount of paper and the conveyance state based on the mark value.

Referring to Figures 3 to 5 attached to the operation and effects of the recording paper remaining amount and the operation state inspection apparatus of the ATM according to the present invention configured as described above are as follows.

First, the load sensor 10 detects the presence or absence of the recording paper 40 and transmits it to the central processing unit 70. When the central processing unit 70 determines that there is a paper by searching for this transmitted signal, In operation, the recording paper feed motor is driven to transfer the recording paper 40.

The conveyed recording paper 40 is transferred to the printer 30 which prints the data on the recording paper after passing through the mark sensor 20, and printing is performed. In this case, the mark sensor 20 passes through the recording paper 40. Mark is detected.

That is, the mark of the normal trading section and the mark of the journal and section are periodically recorded on the recording paper, and the length of the paper to be transferred during printing is not constant. It will always detect the mark.

The detected mark value is compared with the reference value in the comparator 60, and the resultant value is applied to the central processing unit 70. The central processing unit 70 stores the mark value in the memory 80, and Change the value to check the end of paper and transfer status.

Here, the end detection of the journal uses the mark value accumulation method and the mark generation period inspection method to check the end of the paper. First, the mark value accumulation method will be described with reference to FIG.

As shown in (b) of FIG. 4, when the mark is detected, the output value of the mark sensor 20 is output as shown in (a). When the mark value is displayed, the central processing unit 70 increases the memory value by n. If the mark does not appear, the mark value is accumulated by decreasing the memory value by one.

That is, the internal register R and the flag register F are initialized to zero (R = 0, F = 0), and the transaction state is determined and the transaction output value of the comparator 60 is searched if it is 1, R = R-1, and when the output value of the comparator 60 is 0, it changes to R = R + n.

Where R 0 and the output of comparator 60 is zero, then R = 0.

Then, the R value changed as described above is compared to the Near-End value, which is a value for determining the end of the paper, and when the R Near-End is changed to the above F = 1, the transaction state is searched and the comparator 60 is described above. It returns to the process of retrieving the output value of and sends a message, JPR NEAR END, when the transaction ends.

That is, if the value accumulated in the memory 80 is more than a predetermined value, it is determined that the end of the paper.

In FIG. 4, 1 represents General Start, 2 represents General Max, 3 represents General Min, 4 represents Local Max, 5 represents Local Min, 6 represents End Max, and 7 represents End Start.

Here, the inspection of the sheet conveying operation state can be seen by the change of the memory value. That is, if the General Min or Local Min value is below a certain value in the mark value accumulation method, it means that the paper is not conveyed while the white paper part is jammed in the mark sensor 20. If a certain value is exceeded, it is determined that the paper is out of the normal range, and the machine is stopped until the new paper is replaced after completing the current transaction.

Therefore, when the cumulative value of the memory is greater than or equal to the predetermined value A or less than or equal to the predetermined value B, it is determined that the paper is not conveyed normally.

If the paper is not conveyed normally, the mark sensor is malfunctioning, the conveying motor is not working normally, or the power supply is not working properly.

Next, the determination of the end of the paper by the mark generation period inspection method increases the STATUS whenever the mark appears and disappears, as shown in FIG.

If the period where the mark does not appear is long (approximately 2 cm), the above-described STATUS is set to 0, and this method is periodically performed, and when the above-mentioned STATUS reaches 6, it is determined as the end of the paper.

Here, one mark is marked on the top of the recording paper, and three marks are displayed in front of a certain section (for example, 30cm) at the end of the paper, indicating that the recording paper is exhausted, and at the same time after warning with a 30cm margin. It becomes available.

As described above, the present invention can simultaneously determine the end of the recording paper and the machine state by its output value using a mark sensor, so that a device for inspecting the recording paper is unnecessary, so that the recording paper and the operating state are improved. The complexity of the device can be eliminated due to the addition of a device for checking.

In addition, even if the end of the paper appears, a certain time until the end of the transaction has the effect that the normal operation is possible.
