As a sheet separating and feeding device configured of a gate roller or the like fixed in the sheet feeding direction and separating the fed sheets one by one and conveying the separated sheets to a subsequent conveyance path, for example, JP-A-63-71140, JP-A-59-205694,
An apparatus disclosed in Japanese Utility Model Laid-Open No. 3-28129 is known.

[0003]

In the apparatuses disclosed in the above publications, the length of the paper sheet that can be handled in the feeding direction is constant, or the length is different within a range of at most 20 to 30%. However, it was not possible to handle paper sheets that differed greatly such that the length in the feeding direction was two to three times. That is, in the conventional general sheet separating and feeding apparatus, the distance from the sheet holding point of the feed roller and the gate roller to the sheet holding point of the subsequent conveyance path is determined by the feeding direction of the sheet to be handled. Since the length of the sheet is set to be shorter than that of the shortest sheet, the length of the paper sheet in the feeding direction is 2-3 times longer than that of the shortest sheet. Is required to be continuously driven, which causes a problem that a subsequent sheet is erroneously fed. Separately, as described above, the distance from the sheet holding point of the feed roller and the gate roller to the sheet holding point of the subsequent conveyance path is determined by setting the length of the handling sheet in the feeding direction to be the shortest. Therefore, the degree of freedom of the position of the paper sheet holding point on the subsequent transport path is greatly restricted. The latter problem is a limitation in obtaining a common banknote transport path when combining a plurality of banknote (banknote) separating and feeding devices such as an automatic teller machine.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a feed roller which separates and conveys sheets fed by a pickup roller and a gate roller for feeding the stacked sheets one by one. A first nipping conveyance interlocked with and driven by the feed roller for nipping and feeding a fed sheet to a subsequent conveyance path, which is located near a nipping point between the gate roller and the feed roller. Means, and a second conveying path, which is provided between a point at which the first nipping and conveying means clamps the paper sheet and a point at which a subsequent conveyance path clamps the paper sheet, and which is interlocked with and driven by the feed roller . And the switching means for switching between the effective and ineffective states of the sheet conveyance by the second sheet conveyance means according to the length of the sheet to be handled.

[0005]

In the paper sheet separating and feeding apparatus according to the present invention, it is possible to convey various kinds of paper sheets whose length in the feeding direction is within a predetermined range to a conveyance path at a subsequent stage.
Further, when stopping the feeding of the paper sheet, the stopping operation does not have to be unnecessarily delayed for the paper sheet having a long length in the feeding direction. The problem of inviting does not occur. Further, since the distance from the sheet holding point of the feed roller and the gate roller to the sheet holding point of the subsequent conveyance path is substantially variable, the position of the sheet holding point of the subsequent conveyance path can be freely adjusted. The degree of freedom can be increased, and when this is used for an automatic cash transaction apparatus, the degree of freedom of the configuration is greatly improved.

In each of FIGS. 5 to 8, (a) shows a situation in the middle of feeding, and (b) shows a situation when feeding is stopped. 5 to 8, the mechanical configuration is the same, and in the arrangement, the position of the above-described guide member 37 changes according to the length of the bill, and as a result, the pinching force of the second pinch roller 27 decreases. in 5 and 7 of the stateless, is different that the state of chromatic 6 and 8.

First, the dimensions and arrangement of the rollers will be described. Feed roller 22 and pickup roller 21
In order to feed out one bill per rotation, the diameter is set to 40 mm so that the outer circumference is longer than the maximum bill length. Further, the distance from the first pinch roller 25 to the bill holding start point 29 of the subsequent conveyance path 3A is a state where the holding force of the second pinch roller 27 is not applied.
It is about 70 mm so that 01 and 203 can be delivered. From the second pinch roller 27 to the subsequent conveyance path 3A
Is set to about 45 mm so that the banknote 202 having a minimum length of 50 mm can be transferred. Next, a description will be given of an operation control method when the feeding operation is started and then stopped at a predetermined feeding number. The general operation is that the feed roller 22 and the pickup roller 21 are rotated by the motor 9A, and the fed banknotes separated one by one are only the feed roller 22 and the first pinch roller 25 or only the feed roller 22 and the second pinch roller 25. 27, and is delivered to a clamping start point 29 of the subsequent transport path 3A.

First, a case of handling bills 201 and 203 having a length of 75 mm or more will be described with reference to FIGS. In this case, as described above, since the holding force of the second pinch roller 27 is not applied when the safe 1A is set, the number of passing banknotes is counted by the passage detection sensor 39, and the predetermined number of banknotes is passed. When the passage of the rear ends of the final bills 201 and 203 is detected, the motor 9A is stopped instantaneously. As a result, the frictional members 31 and 32 of the pickup roller 21 and the feed roller 22 do not come into contact with the next bills 201 'and 203', so that these feeding operations are not started. As shown in FIG. 6 and FIG. 8, when handling bills 202 and 204 having a length of less than 75 mm, as described above, the pinch roller 27 is in a state where the pinch roller 27 acts on the bills. Detection sensor 3
At 9, the number of passing banknotes is counted, and a predetermined final banknote 20 is counted.
The motor 9A is stopped after the time required for the trailing end of the bill to pass through the pinch roller 27 has passed from the time when the trailing end of the bill 1,203 is detected. Also in this case, the feeding operation of the next bills 201 'and 203' is not started. Where simply the second pinch roller

A banknote in the range of ~ 100mm is loaded into three safes, and the upper guide 37 of the safe 1A is adjusted according to the length of the banknotes. One banknote can be paid out and transported to the subsequent transport path 3A. In addition, when the feeding is stopped with a predetermined number of bills, the second pinch roller 27 can be arranged according to the length of the bills, so that the stopping operation is not unnecessarily delayed even for long bills. And the likelihood of starting the next bill delivery can be reduced. Note that the above embodiments are merely examples of the present invention, and it is needless to say that the present invention is not limited to these embodiments. For example, the present invention is widely applicable not only to banknote handling apparatuses but also to other general paper sheet handling apparatuses.

[0013]

As described above in detail, according to the present invention, it is possible to reliably carry out separation and feeding even for paper sheets having greatly different lengths, and to provide a paper sheet for a subsequent conveyance path. This has the effect of realizing a paper sheet separating and feeding device capable of arranging the kind holding points with a large degree of freedom. Further, since the distance from the sheet holding point of the feed roller and the gate roller to the sheet holding point of the subsequent conveyance path is substantially variable, the position of the sheet holding point of the subsequent conveyance path can be freely adjusted. The degree of freedom can be increased, and when this is used for an automatic teller machine, the degree of freedom in configuration is greatly improved.
