2. Description of the Related Art As a conventional paper sheet separating and feeding mechanism of this type, a mechanism shown in FIG. 4 is known. Figure 4
The basic structure of the separating and feeding mechanism shown in (1) is that the feed roller 11 is fixedly attached to the shaft of the apparatus main body 20, and the non-rotating gate roller 12 is attached so as to face the same. Then, by these, the paper sheets are separated and fed out one by one. Here, the paper sheets stored in the cassette box 10 receive the conveying force of the pickup roller 13 and are fed by the feed roller 1.
1 is fed between the roller 1 and the gate roller 12, but when the paper sheets stored in the cassette box 10 have creases or tears or misalignment occurs during storage,
The sheet is not normally fed between the feed roller 11 and the gate roller 12, and a feeding error or a double feeding abnormality is detected, or the paper sheet is buckled and bent, and the buckled paper sheet is fed to the feed roller 11 and the gate roller 12. Since the apparatus may stop due to the separation jam that stops before 12, the front plate guide 30 is provided between the pickup roller 13 and the feed roller 11 to cope with this. On the other hand, the method for detecting the presence / absence of paper sheets stored in the cassette box 10 is as shown in FIG.
A method of using the empty detection recognition sensor 40 attached so as to block the paper sheet, or a method of bringing a detection lever or the like into contact with the paper sheet and detecting the presence or absence of the paper sheet by the movement of the detection lever. Is used. The cassette box 10 is usually configured to be attachable to and detachable from the apparatus main body, and a sensor 41 for detecting the presence or absence of the cassette box 10 is provided. Incidentally, JP-A-3-111355

The former of the above-mentioned prior art,
That is, in the paper sheet separating and feeding mechanism shown in FIG.
As shown in FIG. 4, the front plate guide 30 contacts the paper sheet 5,
The paper sheet 5 to be delivered by the pickup roller 13 tries to be guided between the feed roller 11 and the gate roller 12. However, it is difficult to match the outer peripheral surface of the feed roller 11 and the tip portion 30a of the front plate guide 30 described above, and generally, a space is formed between the paper sheet 5 and the front plate guide 30. As shown, thin paper sheets 5
Regarding a, the paper sheet 5a is bent and buckling occurs. In order to prevent this, when the front end 30a of the front plate guide 30 is made to be a tangent line between the feed roller 11 and the pickup roller 13, a longitudinal curl that is rounded and curled in the longitudinal direction (direction perpendicular to the paper surface of the drawing) (see FIG. 6). When trying to separate and feed out the paper sheet 5 under the condition called
As shown in FIG. 6, the front end 5b of the paper sheet 5 is attached to the front plate guide 30.
There is a problem that the tip 5b of the paper sheet 5 cannot come into contact with the pickup roller 13 upon contact with a and cannot be separated.

Separately from this, the cassette box 1
The empty detection recognition sensor 40 for detecting the presence / absence of paper sheets stored in 0, the sensor 41 for detecting whether or not the cassette box is loaded in the apparatus main body, and the like are used to confirm the presence / absence of paper sheets. There is also the problem that a sensor is needed. On the other hand, the latter of the above-mentioned conventional techniques, that is, Japanese Patent Laid-Open No. 3-11
In the paper sheet feeding mechanism disclosed in Japanese Patent No. 1355,
A friction roller that comes into contact with the end surface of the paper sheet in parallel from the outside is provided, but this is also a problem similar to the above in that the tip of the paper sheet is accurately guided between the feed roller and the gate roller. Is to have. The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-mentioned problems in the prior art, regardless of the state of the stored paper sheets, that is, to the paper sheets. Even if the paper is thin or has a crease or breakage, it can be reliably fed between the feed roller and the gate roller, and a paper separating / feeding mechanism with less buckling or separation jams can be installed. To provide.

[0005]

SUMMARY OF THE INVENTION The above-mentioned object of the present invention is to make a pickup roller for feeding a paper sheet that is rotated by contacting the upper surface of a large number of accumulated paper sheets, and a single sheet paper sheet that has been fed out. In a paper sheet separating and feeding device having a feed roller that rotates and a gate roller that does not rotate, which are arranged to face each other so as to be separately conveyed, the paper sheet separating and feeding device is configured to be rotatable around a rotation axis of the feed roller. This is achieved by a paper sheet separating and feeding mechanism, which is characterized in that a paper sheet guide member that comes into contact with the upper surface of the accumulated paper sheets is provided.

[0006]

In the separating and feeding mechanism according to the present invention, when the paper sheets are fed one by one from the feeding portion, the thickness of the paper sheets stored in the cassette box, the crease, and the breakage,
Even if there is misalignment or the like, it is possible to reliably feed the leading edge of the paper sheet between the feed roller and the gate roller and prevent buckling or separation jam. By configuring the paper sheet guide member as described above, it is possible to detect the presence or absence of the paper sheet in the cassette box with only one sensor without adding any member other than the paper sheet guide member, and It becomes possible to detect the presence or absence of the cassette box itself.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 3 is a schematic diagram of the entire configuration of the automatic teller machine having a bill separating / feeding mechanism (hereinafter, simply referred to as “separating and feeding mechanism”) according to an embodiment of the present invention, and the bills stored in the cassette box 10 are shown. A predetermined number of sheets of paper are fed from the separating and feeding mechanism and accumulated in the accumulating portion 16 of the dispensing port via the conveying path 15. 1 is a side view showing a detailed configuration of a main part of the separating and feeding mechanism of the automatic teller machine shown in FIG. 3, and FIG. 2 is an arrow A in FIG.
It is the front view seen from the direction. The separating and feeding mechanism according to the present embodiment will be described below with reference to the drawings. In the separating and feeding mechanism according to the present embodiment, the feed roller 11 and the pickup roller 13 are fixedly attached to the shaft of the automatic teller machine body 20, and are fed in the same direction by a feeding motor (not shown). It is driven at the same speed. On the other hand, the movable guide member 1 that comes into contact with the banknote 5 has the feed roller 11 via the bearing 2.
Is attached to the rotary shaft 18 of the feed roller 1
It is configured to be rotatable independently of the rotation of the first rotary shaft 18.

Further, a predetermined load is constantly applied to the bill 5 by the spring 3 which connects the conveyance guide plate 31 attached to the automatic teller machine body 20 and the rear end 1a of the movable guide member 1 described above. It is configured to add. Due to the bill separating / feeding mechanism configured as described above, there is no space in which the bill can buckle between the feed roller 11 and the pickup roller 13, and thus a thin bill, a bill with a crease or a tear, and a bill for storing Even in the case of misalignment, the banknotes can be reliably fed between the feed roller 11 and the gate roller 12. Further, since the movable guide member 1 is rotatable, the movable guide member 1 retracts around the feed roller 11 even when the "conditional banknote" having the above-mentioned longitudinal curl is separated and fed out. As shown in FIG. 7, the bill 5 is in contact with the pickup roller 13, and the tip 5b of the bill 5 is directed along the outline of the movable guide member 1 between the feed roller 11 and the gate roller 12 so that the separating / feeding is normally performed. It will be possible.

Further, the rear end 1a of the movable guide member 1 described above.
When there are banknotes 5 stored in the storage unit, the sensor 4 attached to the above-mentioned transport guide plate 31 is used.
