[Industrial application field]

The present invention relates to a medium conveyance determination device that determines the conveyance state of a medium such as a passbook in an automatic teller machine or the like.

2. Description of the Related Art In recent years, many automatic teller machines have been installed in banks and the like, which allow customers to make deposits and payments through operations. In the case of payment, the customer usually inserts his/her passbook into the slot,
Operates buttons for payment instructions, amounts, etc., and inserts banknotes into the payment slot. The bankbook automatically taken in by the conveyance means is automatically processed by the convenience store inside the bank, and the predetermined amount to be paid is printed on the bankbook before being carried out.

At this time, the state of the inserted medium, ie, the passbook, is left to the customer himself and is not checked by a third party. Therefore, for example, troubles such as inserting banknotes while being stuck in a passbook and causing the banknotes to separate and fall during transportation,
A problem is occurring where the next customer inserts data while the previous customer is being processed.

Therefore, there is a need for technology that can quickly detect abnormalities in media being transported in automatic teller machines whose operation is left to customers.

[Conventional technology]

FIGS. 6(a) and 6(b) are explanatory diagrams of the prior art. In the figure, A, B, and C are sensors as detection means,
10 is a conveyance path as a conveying means, 11 is a passbook as a medium, and 12 is a banknote sandwiched between the media. The passbook 11 inserted from the insertion slot is sucked onto the conveyance path 10, and is detected in the order of sensors A, B, and C, and the conditions of the detection signal output from the sensors are B=C=1 and A=0. It is transported until it becomes . Here, "1" means that there is a medium, and "0"
is the case where there is no

In this way, the conventional conveyance state has been detected depending on whether the sensor conditions satisfy the above conditions.

[Problem to be solved by the invention]

As shown in FIG. 6(b), when a banknote is inserted into a passbook while being sandwiched and separated during transportation, and the banknote 12 is caught and stagnated at the position of sensor A, sensor A will detect A=1. Since the conveyance operation is further continued to detect whether the medium length is long or not, the passbook 11 is carried further back than the intended position, and the jammed state of the banknotes 12 becomes even worse. The above sensor detection conditions are not satisfied and it is determined that there is a conveyance abnormality.

In this way, the conventional method does not have a function to detect abnormalities in the medium at an early stage, so the medium is fed too much, resulting in paper jams, or the banknotes 12 coming off the conveyance rollers and becoming impossible to remove. There was a problem.

In addition to the process of detecting the arrival of a medium at a predetermined sensor position, it is an object of the present invention to
A media conveyance determination device that detects abnormalities in the medium during conveyance at an early stage by comparing the distance between two sensors and immediately stopping conveyance of the medium when the relationship does not satisfy predetermined conditions. It is about providing.

[Means to solve the problem]

FIG. 1 is a diagram showing the principle configuration of the present invention. The present invention provides a transport means OG for transporting the inserted medium OD, and a transport means OG for transporting the inserted medium OD, and the medium transport means OG for detecting the medium length of the medium 01).
0), a plurality of detection means (1) arranged at predetermined intervals on the medium transport means αO subsequent to the medium length detection means Q31; Of the means (1), the medium length (x) detected by the first detecting means on the side where the medium (11) is inserted is compared with the distance (dl, d2) between the subsequent adjacent detecting means,
The present invention is characterized in that it includes determining means (3, 4, 5) for determining whether or not the conveyance state of the medium is appropriate based on the comparison result.

[Effect]

In the present invention, the medium length is detected by the first detecting means on the upstream side of the conveyance path, and a plurality of sensors are arranged at predetermined intervals in the succeeding stage, so that the distance between the first detected medium length and the subsequent adjacent detecting means is The distance (cll, d2>) is compared, and based on the comparison result, it is determined whether the conveyance state of the medium is appropriate.

〔Example〕

FIG. 2 is a block diagram of an embodiment of the medium conveyance determination device of the present invention. In the figure, 1 is a plurality of sensors arranged on the transport path 10, 2 is a comparator that converts the analog output of each sensor into digital, 3 is a multiprocessor that performs comparison, judgment, transport control, etc., and 4 stores a processing program. ROM to
, 5 is a RAM for storing the medium length, and 6 is a drive circuit for a motor 7 that transports the medium.

FIG. 3 is an explanatory diagram of the present invention. As shown, sensors 1 to 5 are placed on the conveyance path 10 at the illustrated intervals a, b.

They are arranged in c and d. Let X be the medium length of the medium inserted from the insertion port. Here, the intervals a, b.

c and d are set to predetermined values in advance. Further, it is assumed that the conveyance starts when the medium is set in the insertion slot and stops when the medium is detected by the sensor 5.

In this case, for ease of explanation, the media is
It may be detected by one sensor, but three consecutive
It shall not be detected by more than one sensor at the same time.

FIG. 4 is a basic flowchart showing the processing procedure of the present invention.

First, check step 1) to see if the medium is set from the insertion slot. When set, measure the number of steps the medium takes when passing sensor 1, calculate the medium length from the number of steps, and make a note of the medium length X. ! Store it in JRAM5 (Step 2).

After the medium length is stored, a medium abnormality check process starts in parallel with the conveyance of the medium (step 3). In this medium transport process, when the sensor 5 detects the medium (step 4), the transport and medium abnormality check are terminated (step 6).

Here, the medium abnormality check process shown in step 5 will be explained in more detail.

FIG. 5 is a detailed flowchart of the medium abnormality check process of the present invention. In the figure, "1" indicates that a medium is present, and "0" indicates that there is no medium. The flowchart will be explained with reference to FIG. This flowchart shows that when a medium is detected by sensor (i), the sensors (i-1) on both sides of it, (
The detection state of i+1) is checked.

When the medium is detected by sensor 2 (1), sensor 1
Compare the distance a between the sensor 2 and the medium length X2), a
>X, check the detection state of sensor 1 (3
). Here, if sensor 1 detects that there is a medium, it means that sensor 1 has detected something that should not have been detected by sensor 1 because the medium length is shorter than the distance, and there is some abnormal object between them. QS detects an abnormal medium, stops transport, and issues an alarm).

In step 3, if there is no medium at sensor 1, then compare the distance between sensor 2 and sensor 3 with the medium length 5) If there is a medium, the conveyance is stopped as an abnormal medium is detected and an alarm is generated α
ω.

When the medium length is larger than the distance in step 4,
If there is no medium in sensor 3 in step 5, the sensor 4 and sensor 5 determine whether there is a medium (6), and if there is a medium, the conveyance is stopped and an alarm is generated in step 15 as described above. do.

If there is no medium in step 6, the process returns to the first step 1.

Further, the distance C between the sensor 3 and the sensor 4 and the medium length X can also be determined in the same manner as described above, as shown in steps 7 to 10.

Furthermore, the distance d between the sensor 4 and the sensor 5 and the medium length
Also, the determination can be made in the same manner as described above as shown in steps 11 to 14.

In the above, the conditions for the inter-sensor distance and medium length are such that three consecutive sensors do not simultaneously detect the medium, but even in cases other than these conditions, the sensor that detected the medium and all other sensors A similar effect can be obtained by calculating the distance to and comparing that value with the medium length.

〔Effect of the invention〕

As described above, according to the present invention, in addition to the process of detecting the arrival of the medium at a predetermined sensor position, the size of the medium length and the distance between two adjacent sensors are further compared,
Since conveyance of the medium is immediately stopped when the relationship does not satisfy a predetermined condition, an abnormality in the medium being conveyed can be detected at an early stage without the need for special hardware. Furthermore, in order to compare the sensor spacing, which is known data, with the medium length measured at the time of insertion,
This has the advantage that it can be checked no matter what length of medium is being conveyed.
