BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet separating apparatus used for an automatic cash dispenser or an optical character reader.

[0002]

2. Description of the Related Art Conventionally, for example, in an automatic cash dispensing apparatus, a sheet separating apparatus for feeding out sheets (banknotes) one by one into the apparatus has been used. Hereinafter, the configuration of a conventional sheet separating apparatus will be described with reference to the drawings. FIG. 4 is an internal configuration diagram of the automatic teller machine, and FIG. 5 is a side view of a conventional sheet separating device.

[0003] In FIG. 4, a paper sheet storage box 2 is mounted inside an automatic cash dispenser 1. A bill (not shown) is stored in the paper storage box 2.
The automatic cash dispenser 1 is provided with a payout mechanism 3. The payout mechanism 3 is provided with a payout roller (hereinafter, referred to as a pickup roller) 4 for feeding out bills from the paper sheet storage box 2, and the pickup roller 4. It comprises a feed roller 6 for feeding the fed bills to the transport path 5 and a reverse roller 7 for feeding back the second and subsequent bills when two or more bills are fed. The bills fed by the feeding device 3 pass through the transport path 5, are discriminated by a discrimination unit (not shown), and are accumulated in the temporary storage unit 8. When a predetermined number of bills are sent to the temporary storage section 8, the bills are sent out from the payout port 9.

Next, referring to FIG. 5, the internal structure of the paper sheet storage box 2 will be described in detail. An intermediate plate 11 for loading the banknotes 10 is provided inside the paper sheet storage box 2, and a loading door 1 that is opened and closed when the banknotes 10 are loaded is provided on the upper surface of the storage box.
2 are provided. On the intermediate plate 11, the banknotes 10 are stored in a vertically placed state. Inside the loading door 12, an upper surface door 14 that opens and closes the opening 13 of the paper sheet storage box 2 is provided on condition that the paper sheet storage box 2 is attached to the automatic teller machine 1. A movable plate 16 that presses the banknotes 10 stored in the stacked state toward the banknote holder 15 is provided in the paper sheet storage box 2.
The movable plate 16 is movably supported in the direction of arrow AA ′ and has one end connected to the intermediate plate 11.
And a tension spring 17 having the other end fixed to the movable holding plate 16 is urged in the direction of arrow A ′, that is, toward the bill holder 15.

[0005] The banknote 1 is stored in the paper-sheet storage box 2 having such a configuration.
When the banknote 0 is stored and attached to the automatic cash dispenser 1, the pickup roller 4 protrudes from a not-shown notch of the banknote holder 15, and comes into pressure contact with the leading end of the banknote 10 in the paper sheet storage box 2. Thereafter, the pickup roller 4 is rotated,
The bill 10 is sent upward. When the banknote 10 is inserted between the feed roller 6 and the reverse roller 7, the banknote 10 is fed further upward by the rotation of the feed roller 6 in the direction of arrow B. If two sheets are stacked, the second and subsequent sheets are fed back by the rotation of the reverse roller 7 in the direction of arrow B.

[0006]

However, in the above-described apparatus, when the paper sheet storage box 2 is mounted on the automatic cash dispenser 1 while moving in the direction of arrow A 'shown in FIG.
Pickup roller 4 projecting from bill holder 15 shown in FIG.
Thereby, the bills 10 stored in the paper sheets storage box 2 are pushed back. At this time, one end 10b of the bill 10 is connected to the movable plate 16 by the frictional force between the bill 10 and the intermediate plate 11 of the paper sheet storage box 2 and the frictional force of a guide portion (not shown) for guiding the movement of the movable plate 16. It does not move integrally, and only the bills 10 in contact with the pickup roller 4 are compressed. Therefore, as shown in FIG.
Is mounted with the tip end 10a thereof inclined to the reverse roller 7 side. That is, the rear end portion 10b of the banknote 10 is
There was a case where it leaned so as to approach the bill holder 15 from a.
When the bill 10 is fed out by the pickup roller 4 in this state, the leading end portion 10a of the bill 10 collides with the reverse roller 7 as shown in FIG. 7, and the reverse roller 7 is moved in the direction of arrow B (reverse transport direction) in FIG. There is a problem in that it is pushed back due to the rotation and defective feeding occurs.
FIGS. 6 and 7 are explanatory diagrams showing examples of conventional problems.

[0007] In order to eliminate the above-mentioned problem of poor feeding operation, the present invention properly separates the banknotes one by one by properly adjusting the stacking state of the banknotes after the paper-sheet storage box is mounted. It is an object of the present invention to provide a paper sheet storage box capable of smoothly performing a feeding operation.

[0008]

In order to solve the above-mentioned problems, in a sheet separating apparatus for feeding out stacked sheets one by one, a sheet stacking plate for stacking sheets, a notch, And a holding plate having a portion, which is movable along the sheet stacking plate and is urged in the direction of the holding plate to clamp sheets on the sheet stacking plate between the holding plate and the holding plate. A movable plate,
A sheet storage box having a pressing guide for pressing the rear end of the sheet in contact with the sheet stacking plate on the holding plate toward the movable plate, and protruding from a notch of the holding plate. A pickup roller for feeding the paper sheet, a feed roller positioned above the pickup roller for feeding the paper sheet fed by the pickup roller to a transport path, A reverse roller that feeds back the second and subsequent sheets when more than one sheet is fed out, and the pressing guide guides the leading end of the sheet toward the feed roller from the tangent line of the pressure contact of the feed roller and the reverse roller. It is inclined.

[0009]

When a sheet storage box loaded with sheets is attached to an automatic cash dispenser, a pickup roller protrudes from a cutout portion of the holding plate, and the leading end of the sheets stacked in the sheet storage box. Contact with the department. In this state, since a pressing guide is provided for pressing the rear end of the sheet in contact with the sheet stacking plate toward the movable plate, the rear end of the sheet is more movable than the pickup roller. Approach the board side. Therefore, the leading end of the paper sheet is inclined toward the feed roller side more than the tangent of the pressure contact point between the feed roller and the reverse roller, and the stacking state becomes proper. Thus, since the feed roller rotates in the transport direction, the paper sheet is transported upward without fail.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. Elements common to the drawings are denoted by the same reference numerals. FIG. 1 is a side view showing a paper sheet storage box according to an embodiment of the present invention, which is attached to an automatic teller machine. FIG. 2 is a side view showing the paper sheet storage box before being attached to the cash dispenser according to one embodiment of the present invention,
FIG. 3 is a front view showing a paper sheet storage box according to one embodiment of the present invention.

In FIG. 2, a guide 18 is mounted at a position where a rear end portion 10b of the bill 10 faces the bill holder 15, and an inclined portion 18a which is a wedge-shaped projection is formed at a lower end portion of the guide 18. ing. Guide 18
For example, it is made of a low friction member such as plastic.
The other structure is the same as that of the prior art. When the bill 10 is loaded into the paper sheet storage box 21 configured as described above, the leading end 10a of the bill 10 is attached to the bill holder 15, and the rear end 10b. Are in contact with the tip of the inclined portion 18a of the guide 18, respectively, and the tip 10a of the bill 10 is
It is in a state of being inclined obliquely so as to be closer to the bill holder 15 than b. In the present embodiment, in FIG.
Numeral 8 is fixed to a position directly below the pickup roller when the paper sheet storage box 21 is mounted on the automatic cash dispenser 1.

In FIG. 1, when the paper sheet storage box 21 loaded with the bills 10 is mounted on the automatic cash dispenser 1, the pickup roller 4 protrudes from the notch 15a of the bill holding plate 15 shown in FIG. It comes into contact with the tip 10a of the banknotes 10 stacked in the leaf storage box 21. In this state, since the guide 18 for pressing the rear end 10b of the bill 10 in contact with the intermediate plate 11 toward the movable plate 16 is provided, the rear end of the bill 10 is inclined more toward the movable plate than the feeding roller. I do. Therefore, the leading end portion 10b of the paper sheet is tilted toward the feed roller 6 side from the tangent of the pressure contact point between the feed roller 6 and the reverse roller 7, and the stacking state becomes proper. The distance from the bill holding plate 15 to the tip of the guide 18 is higher than the protrusion amount of the pickup roller 4, and therefore, the bill 10
Of the feed roller 6 and the reverse roller 7
The contact point is inclined toward the feed roller 6 side from the tangent line of the pressure contact, and the state of accumulation becomes proper. Thereby, since the feed roller 6 is rotating in the direction B (conveying direction) in FIG. 1, the paper sheet is surely conveyed upward, and the feeding operation is ensured.

Next, the operation of this embodiment having the above configuration will be described with reference to FIGS. When the banknotes 10 are loaded in the banknote storage box 21, the loading door 12 is opened, the movable plate 16 is moved in the opposite direction to the banknote holder 15, and the banknotes 10 are loaded into the banknote storage box 21 and are movable. When the plate 16 is released, the movable plate 16 slides in the direction of the bill holder 15 by the tension of the tension spring 17 to press the bill 10, and
0 is stored vertically.

When the banknote 10 is loaded into the paper-sheet storage box 21 and then attached to the automatic cash dispenser 1, the upper door 14 slides in the direction of arrow A, and the feed roller 6 and the reverse roller 7 from the opening 13 thereof. Part of it enters. Also,
A part of the pickup roller 4 protrudes from the cutout portion 15a of the bill holder 15, and presses the bills 10 stacked in the paper sheet storage box 21. Thereafter, the pick-up roller 4 rotates and sends the bill 10 upward. As a result, the bill 10 enters between the feed roller 6 and the reverse roller 7. When the feed roller 6 and the reverse roller 7 are rotated in the direction of arrow B, the first bill 10 is separated and sent further upward. If two sheets are stacked, the second and subsequent bills 10 are prevented from being fed out by the reverse roller 7. Subsequent operations are the same as in the related art.

In FIG. 1, the bill 10 is pressed against the pickup roller 4 with the tip 10a inclined toward the feed roller 6, so that when the bill 10 is fed out by the pickup roller 4 as it is, 10
Does not hit the reverse roller 7 but is fed out toward the feed roller 6.

The guide 18 is formed of a low friction member.
Moreover, the rear end portion 10b of the banknote 10 has a wedge- shaped inclined portion 18.
When the bills 10 are fed out one by one by the pick-up roller 4, the bills 10
Stable feeding is performed almost without being affected by the frictional force of the guide 18. Further, the guide 18 is installed immediately below the pickup roller 4 and can be reliably fed to the feed roller 6 even if both side end portions of the banknote 10 not regulated by the inclined portion 18a are slightly curved. Further, also in the separating operation, when the remaining separated bills 10 are returned by the reverse rotation of the pickup roller 4, the rear end portion 10 b of the bills 10 does not enter a malfunction state as shown in FIG. And moves back to the intermediate plate 11.

[0017]

[Effects of the Invention] The present invention is configured as described above and has the following effects. The leading end of the bill is inclined toward the feed roller side from the tangent line of the pressure contact point between the feed roller and the reverse roller so that the bills are properly stacked, conveyed reliably upward, and the feeding operation is ensured.
