sent to.

Therefore, when a plurality of paper sheets 6 are sent out to the outlet 1 at one time, they are separated into one sheet by the gate row 23.

Therefore, the gap between the feed roller 2 and the gate roller 3 is an important point for preventing skew, and if there is a difference between the gaps between the left and right feed rollers 2 and the gate roller 30, skew will occur.

When the gap between the feeding roller 2 and the gate roller 3 changes during assembly adjustment or during use after installation and needs to be readjusted, the specified adjustment bill should be readjusted. 2 and the gate roller 3, and the adjustment dial 8 was used to adjust the adjustment banknote by pulling it with a tension gauge and adjusting it to a specified tension.

[Problem that the invention seeks to solve]

However, according to the above-mentioned conventional technology, there is a problem in that it takes time to check the gap adjustment between the feed roller and the gate roller, and whether or not the adjustment is appropriate depends only on whether or not jams or other problems occur. The problem is that I don't understand.

Furthermore, the gap between the left and right feed rollers and the gate roller may differ due to wear of the feed roller or gate roller, changes in the gap due to paper dust or rubber adhering to the surfaces of both rollers, and differences in the degree of wear of the feed roller or gate roller. There was no way to display the occurrence of frequent errors, and as a result, problems such as jams eventually occurred.

[Means for solving problems]

The present invention provides a means for detecting a skew value and a skew direction of paper sheets to be separated and fed, a means for determining whether the detected skew value is within two reference values, an upper limit and a lower limit, and a skew value. The present invention is characterized by comprising means for notifying when the row value is within the reference value.

[Effect]

According to the above invention, by detecting the skew value and the skew direction of the paper sheets to be separated and fed, it is determined whether or not the detected value is between the set upper and lower limits. , when it is within the two reference values, it is notified, and when it is outside the reference value, it is also notified.

As shown in FIG. 7, the skew amount H is in the area B where jams, bill breaks, bill bending, and other obstacles do not occur on the conveyance path.
The upper limit value is set to a value obtained by subtracting a margin amount C that takes into account variations depending on the type and condition of banknotes.

If the skew amount for each banknote withdrawn as described above is equal to or greater than the specified amount H, then the amount of skew for each banknote withdrawn to the left is equal to or larger than the specified amount H.
An ED lamp 66 and an LED lamp 68 light up when there are 1,000 tickets. In the case of leading to the right, if the skew amount is greater than the specified amount H, the LED lamp 67 is lit when there are 10,000 tickets, and the LED lamp 69 is lit when there are 1,000 tickets.

The LED lamps 70 and 71 indicate that the banknotes in the skew area B, which are equal to or greater than the skew amount H and where no failure occurs, are at a specified ratio to the total banknotes dispensed (1 in the case of right-hand lead, 2 in the case of left-hand lead). ), it remains off, but it lights up if it is more than a predetermined percentage of the total bills dispensed, and it blinks if bills with a skew area of 8 or more are dispensed.

When the LED lamps 70 and 71 light up or blink for the total amount of banknotes that have been withdrawn, if there are many left-hand leading banknotes, the LED lamp 66.68° is turned on, and if there are many right-hand leading banknotes, the LED lamp 67.69 is turned on. let When the next transaction is started, all the LED lamps 66 to 70 are turned off.

Next, an adjustment method during assembly or an adjustment method when the feeding roller becomes skewed due to gate roller wear or the like and needs to be readjusted will be explained.

First, as shown in FIG. 4, the bill peg 19 is pulled out by opening the rear door 64 of the automatic teller machine. Then, the feed roller 2 and gate roller 3 of the safe to be adjusted, for example, the million safe 73.
To adjust the gap, insert paper and turn adjustment knobs γ4 and 75 until the specified tension is reached.

The specified tension is set near the lower limit of the area where there is little skew and no single run. Then, for confirmation, a 10,000-ticket withdrawal transaction is performed, and if the LED lamp 71.66 is turned off, the adjustment is completed. At this time, for example, if the LED lamp 71 is lit or flashes and the LED lamp 66 is lit, that is, if there are many bills with the left side leading, the adjustment knob 74 is moved in the direction of narrowing the gap between the left feeding roller 2 and the gate roller 3. Turn. The adjustment is completed when the LED lamps 71 and 66 go out.

If you turn the adjustment knob too much, that is, the LED lamp 71 lights up or flashes, and the LED lamp 67 lights up, turn the adjustment knob in the opposite direction and turn the LED lamp 71.6 on.
Turn until the number 7 disappears.

After operation, the same procedure is carried out when readjusting the gap between the gate roller and the delivery roller in the safe section, where large siskius cases occur frequently due to wear of the reverse roller or the like.
