くなって来ている．又、メンテナンス性の向上ならびに
廉価性の追求も切望されている。The device described in JP-A-5-6-57-3-4 uses a plurality of friction rolls and a reversing belt with a simpler configuration than before in order to take out paper sheets one by one. It is arranged on the opposite side of this friction roll. JP-A No. 63-282032 also discloses a comparison method in which a plurality of friction rolls are arranged in the front and back direction along the feeding direction of paper sheets and a spring mechanism is built into the gate roller in order to take out paper sheets one by one. A complex structure is adopted. Furthermore, Utsukai Showa 63-183
In No. 136 as well, in order to take out paper sheets one by one, a plurality of friction rolls are arranged in the front-rear direction along the feeding direction of the paper sheets, and a second (first) sheet is placed near both sides of the rear roll. It has a structure in which a braking pad is installed on the front side to suppress the lower paper leaves. (Problems to be Solved by the Invention) As described above, in a device for dispensing banknotes, etc., a dispensing roll is provided as a basic structure, while a means for suppressing the dispensing is provided on the back side. The most important issue is how to prevent the double-sheet feeding phenomenon (overlapping feeding). In addition to this, a major challenge is to avoid complicating the device structure and improve reliability. Also, in order to prevent paper sheets from being fed out twice, it is important to be able to maintain a stable contact force between the paper sheet and the feed roll under all circumstances, and it is important to maintain this stable contact force. Another major challenge was how to perform the Dakkai without using a complicated structure. In particular, in recent years, devices have been widely used in which the bucket portion for storing the paper sheets and the associated portions are configured as one unit and can be detachably attached to, for example, a banknote dispensing machine. The demand for simplification and weight reduction is becoming greater than ever. There is also a strong desire for improved maintainability and lower cost.

く常に安定した付勢力を作用させることが可能である。Under such circumstances, the present invention is capable of reliably preventing the phenomenon of double sheet output, simplifying the structure of the device, and achieving improved maintainability and low cost of the device. The purpose is to provide a structured paper sheet feeding device. (Means for Solving the Problems) The above-mentioned object of the present invention is to hold paper sheets in a stacked state in a paper sheet storage chamber, and a mounting table movably supported is biased in a certain direction by an elastic member. In the paper sheet feeding device configured to sequentially feed out the paper sheets one by one from the front side by a feeding roll provided on the side facing the urging force, the feeding roll is configured to feed out the paper sheets one by one from the front side. a rotatable convex member that temporarily pushes back the placing table in a counter-biasing direction by pressing the outermost part of the paper sheet; and a friction member that slightly advances the outermost part of the paper sheet. a preliminary delivery roll that is engageable and whose rotation is suppressed by elastic means;
A feeding member made of a high-friction member that frictionally engages with the paper sheet and greatly advances the paper sheet in the feeding direction is protruded from the outer circumferential surface of the roll or an extension of the outer circumferential surface with respect to the roll rotation direction. A paper sheet feeding device characterized in that it is configured to come into contact with the paper sheets in the above order can perform the admonition. Embodiments of the present invention shown in the accompanying drawings will be described below. Fig. 1 is a schematic side view of one embodiment of the paper sheet dispensing device of the present invention, Fig. 2 is a perspective view of the dispensing roll, and Fig. 3 is a schematic operational diagram sequentially showing the action of the dispensing roll. ．． The paper sheet dispensing device l shown in FIG. 1 is constructed as a box-shaped unit, and is detachably attached to, for example, a bill dispensing machine. This paper sheet dispensing device 1 is movable up and down within the storage chamber l8 which is the storage space for the paper sheets 20! ! A placing table 2 is provided, and a feeding roll 9 is provided above the storage chamber 18 for feeding out the Giyo sheets 20 stacked on the placing table 18 one by one. A supply roll 3 and a separation roll 4 are provided close to each other (on the downstream side of the unit), and are configured so that the sheets 20 can be supplied one by one to a predetermined conveyance path outside the unit. The mounting table 2 is supported by a slider pull on a plurality of pillars (not shown) and is pulled upward by a coil spring 5 attached to a suitable position at the left end in the figure. Therefore, the mounting table 2 can act so as to press the gyoza 20 against the delivery roll 9. Further, the tip of the coil spring 5 is hooked on a locking pin 6 installed at the upper right end of the unit, and its approximately middle portion is held between the pins 7 and 8 installed at the upper left end of the unit, so that it is held at an approximately right angle. It is bent and attached so that it has a horizontal part along the upper edge of the unit and a vertical part along the side of the unit, making it an extremely long structure. By making the most of the unit space and using a long coil spring 5, the amount of deformation per unit length when the coil spring 5 expands and contracts can be kept small.
In the range where the mounting table 2 moves up and down, this coil spring 5
There is little variation in the spring force between the fully extended state (the stage is at the lowest position) and the state where it is not so stretched (the stage is at the top), so it is always stable regardless of the position of the stage 2. It is possible to apply a certain biasing force.

された繰出部材１５が設けられている。The feed roll 9 is a cylindrical body that rotates around a rotating shaft 16, and includes three elements each having a separate function. The three elements are a relatively small roll-shaped protrusion member 10 on both sides of the body of the delivery roll 9 as a first and second element, and a preliminary delivery part that is thicker than the protrusion member 10. each pair of rolls l2 are provided, and furthermore,
As a third element, a feeding member 15 having a wavy surface is provided on the outer circumferential surface 17 of the body.

The spindle 1 is arranged so that it protrudes in the roll radial direction beyond the extension surface of the spindle 1.
1, it is rotatably mounted. This convex member 1
0 is made of a metal or hard plastic with a slippery surface, and when the feed roll 9 rotates, it presses the outermost surface of the stacked Gyoha 20 downward, thereby resisting the biasing force of the coil spring 5. and move the mounting table 2.
It has a function of applying an impact (temporary vibration) to the coil spring 5.

葉２０ａを僅かに前進させることが出来る。Similar to the convex member 10, the preliminary delivery roll 12 is positioned such that its outer circumferential surface protrudes further outward in the roll radial direction than the extended surface of the body outer circumferential surface 17. The surface of this preliminary delivery roll 12 is made of a rubber material having a relatively high coefficient of friction. The preliminary delivery roll 12 is rotatably mounted around an adjustment screw 14 whose head has a large diameter, and furthermore, the head of the adjustment screw 14 and the side surface of the preliminary delivery roll l2 are connected to each other. A coil-shaped adjustment spring 13 is attached between the roll 12 and the roll 12 to appropriately press the roll 12 from the side. Therefore, by tightening and adjusting the adjusting screw 14, the pressing force of the adjusting spring l3 can be adjusted as appropriate, and the preliminary delivery roll 12
The rotational force of the can be controlled. As a result, when the delivery roll 9 rotates, the preliminary delivery roll 12 can slightly rotate the outermost paper sheet 20a in contact with the paper sheet and slightly advance it by appropriate frictional force.

面に嵌め込むように固定されている。The material and shape of the feeding member 15 are appropriately configured so that the frictional force is larger than that of the preliminary feeding roll 12. For example, the feeding member 15 is made of a high friction material such as rubber, and its surface shape is similar to that of Giyo. The vertical cross section along the sheet feeding direction is shaped like a wave so that the frictional force is high when it comes into contact with the sheet. It should be noted that the feeding member 15 has a corrugated outermost part that slightly protrudes in the radial direction of the roll from the outer peripheral surface 17 of the trunk, and the outer peripheral surface of the trunk so that it occupies an angle of approximately 1/4 of one circumference of the roll. It is fixed so that it fits into the

いることは勿論である。In addition, it is preferable that the width (l) of the feeding roll 9 is configured such that, for example, the preliminary feeding roll l2 contacts the vicinity of both ends of the Gyo 20, since this can maximize its effect. It goes without saying that at least the width (L,) between the preliminary feeding rolls 12 is configured so as not to exceed the width of the Gyoha 20.

の長さを有効に使用することができる。The operation of the main parts of the paper sheet dispensing device 1 configured as described above will be explained in detail with reference to FIG. 3. The delivery roll 9, which had been stopped at a predetermined rotational position, starts rotating in response to an appropriate activation signal generated by the operation of the bill dispensing machine equipped with the paper sheet dispensing device 1 described above. As a result of this rotation, the sheet of paper 20 on which the convex member 10 is stacked first
(A in Figure 3), and this pressure is immediately released as the roll rotates. Due to this pressure, the mounting table 2 is pushed downward and is immediately returned upward by the coil spring 5. By temporarily generating vibration in the coil spring 5, the extension of the coil spring 5 becomes uniform over its entire length. can. That is, since the coil spring 5 is forcibly bent and attached by the pins 7 and 8 as described above in order to increase its length, the biasing force (elasticity) of the spring is reduced at the pins 7 and 8. power is divided,
Although the so-called catching phenomenon of the coil spring 5, which largely depends on the elasticity of the portions below the pins 7 and 8, is likely to occur, the vibration caused by the convex member 10 can prevent this catching phenomenon. Therefore, the original length of the coil spring 5 can be used effectively.

ように更に前進させられる。After a predetermined period of time (in this embodiment, the time it takes for the delivery roll to rotate approximately 90') after the convex member 10 makes contact, the preliminary delivery roll 12 comes into contact with a very delicate touch (see B in FIG. 3). ). That is, under the preset stable urging force condition of the coil spring 5, it is possible to contact the sheet with a slight rotation by the pressure of the adjustment spring 13, so that it is possible to make contact with the paper sheet with a slight rotation that is neither too strong nor too weak. Giyo 20a at the top
It is possible to press the top surface of the roll and drag it in the direction of roll rotation. Due to this flexible abutting action, for example, even if there is a factor that tends to cause mutual catch, such as creases, between the upper and lower adjacent Giyo (the outermost Giyo and the paper sheet below), the outermost Giyo can easily catch on each other. The paper leaf 20a can be shifted to ensure that it is separated from the paper sheet immediately below it. As described above, according to the apparatus of the present invention, unlike the conventional methods, it is not possible to completely prevent the paper sheet below the topmost sheet from interlocking when the topmost sheet begins to move. Compared to other devices, the flexible contact action of the preliminary feeding roll 12 described above prevents double-sheet feeding from the beginning of movement of the outermost sheet, and the reliability of preventing double-sheet feeding is extremely high. It is. In addition, due to this slight rotation during operation, the feed roll 12 always has a different surface in contact with the paper sheet, and can stably maintain the desired effect over a long period of time without uneven wear or eccentricity. Moreover, its lifespan can be extended. Following the contact of the preliminary feeding roll 12, the feeding member l5
When the paper sheet 20a comes into contact with the paper sheet 20a (C in FIG. 3), the paper sheet 20a that has started to shift is sent out in the paper sheet supply direction, and then the paper sheet 20a, which has started to shift, is sent out in the paper sheet supply direction, and is connected to the supply roll 3, which is rotating in the normal direction at a higher speed than the delivery roll 9. It is further advanced so as to be sandwiched between the separation roll 4 which is rotating in reverse.

く保つことができる。The paper sheet 20a supported by the supply roll 3 and the separation roll 4 configured in this way is dragged by the supply roll 3 made of a material with a higher coefficient of friction than the separation roll 4, and is fed out to a predetermined distance. It is pulled out onto the transport path. Further, at this time, the separation roll 4, which is rotating opposite to the supply roll 3 in a direction opposite to the direction in which the Gyoha 20a is pulled out, is configured to more reliably prevent two-sheet feeding. Note that the contact force between the supply member 15 and the paper sheet 20a is exerted by the convex member 10 each time the feed roll 9 rotates, so that a stable force of the coil spring 5 is always applied, which ensures good sheet feeding. Conditions are maintained. Although the present invention has been described above with reference to one embodiment, the present invention is not limited to this, and can be modified in various ways, such as the mounting structure of the coil spring, the position of the feeding roll, and even the number of convex members. Furthermore, the present invention is not limited to the bill dispensing device as in the above embodiment, but can be applied to any device such as a copying machine. (Effects of the Invention) As described above, in the apparatus of the present invention, the outlet roll is capable of handling paper sheets. A rotatable convex member that applies vibration to the loading table by pressing the outermost surface, and a reserve whose rotation is suppressed by elastic means that can be frictionally engaged to slightly advance the outermost sheet of paper. A delivery roll and a delivery member made of a high-friction member that frictionally engages paper sheets and delivers the paper sheets from the storage chamber are configured to protrude from the roll outer peripheral surface or an extension of the outer peripheral surface in this order. has been done. Therefore, the impact from the convex member makes effective use of the long spring attached so that it can be bent, and a stable biasing force can be obtained, thereby stabilizing the contact force between the paper sheet and each part of the feed roll. It is possible to always keep the leaf delivery conditions stable. In addition, compared to conventional devices that cannot completely prevent the paper sheets below the outermost part from interlocking when the outermost paper begins to move, the preliminary feeding roll has more flexible contact. Because the shifting action of the double-sheet feed-out prevention operation is performed from the beginning of the movement of the outermost sheet, the reliability of preventing double-sheet feed-out is improved. In addition, since the feed roll undergoes a slight rotation during the shift operation, a different surface is always in contact with the paper sheet, and the desired action is stably maintained over a long period of time without uneven wear or eccentricity. and its lifespan can be maintained for a long time.
