2. Description of the Related Art A bill storing and feeding device of a type in which bills are stored by winding them together with a tape and then the stored bills are drawn out by rewinding the tape, can store a large number of bills in a small volume. It has an advantage that it can be easily taken out without requiring a special feeding means at the time of feeding.

As a bill storing and feeding device of the above system,
For example, as disclosed in Japanese Patent Laid-Open No. 3-128854, two tapes are used, one end of each tape is wound around two winding rollers that wind only the tape, and the other end of each tape is wound. Is configured to be wrapped around one winding roller that winds the tape and the bill together,
A two-tape type in which banknotes are sandwiched between two tapes for storage and feeding, for example, Japanese Patent Laid-Open No. 58-12
As disclosed in Japanese Patent No. 5558, one tape is used, and both ends of the tape are wound around a winding roller that winds only the tape and a winding roller that winds the tape and the banknote together. There is known a one-tape type in which when one tape is wound up, banknotes are sandwiched between the tape and the tape to be stored and fed out.

In the above-mentioned device, regardless of the number of tapes, the banknotes cannot be stored or fed out unless tension is constantly applied to the tapes. Therefore, conventionally, motors are provided as drive means on the take-up roller side for taking up only the tape and the take-up roller side for taking up the tape and the banknote together, and when each take-up roller is on the side for taking up the tape. The motor is driven to rotate and the one-way clutch is interposed so that the motor does not rotate when the tape is rewound and rotation resistance occurs, or the rotation speed of the motor on the winding side and the rewinding side is controlled. It was devised so that the tape would always be given tension by doing so.

Of these, the large-diameter gear 16 and the small-diameter gears 14, 14 constitute a speed increaser, and the gear ratio is set to about 3: 1 and the second winding roller 7 is Rewinding speed of tape V ₁
As shown in FIG. 6, V ₁ <V ₃ so that the speed V _{3 at} which the first winding rollers 4 and 4 wind the tape is always faster.
Has been set to the relationship. That is, the speed at which the second take-up roller 7 rewinds the tape is highest at the maximum diameter, and conversely, the speed at which the first take-up rollers 4 and 4 take up the tape is slowest. Since the diameter is small, the speed at which the first winding roller 7 rewinds the tapes T and T at the minimum diameter is faster than the speed at which the second winding roller 7 rewinds the tapes T and T at the maximum diameter. It has only to be set so that

One end of the second winding shaft 8 has a cassette 1 at one end.
Has a joint portion 21 having holes 20 and 20 which are connected to pins 19 and 19 of a drive shaft 18 which is exposed to the outer surface of the apparatus body and which is rotated by a motor (not shown) provided on the apparatus body side. When set in a predetermined position, the joint portion 21 engages with the drive shaft 18 to transmit the driving force. Further, the brake is released on the opposite end of the second winding shaft 8 on condition that the cassette 1 is set at a predetermined position, and the negative operation electromagnetic brake 22 that allows the rotation of the second winding shaft 8 is provided. It is provided.

As shown in FIGS. 3 and 4, the second take-up roller 7 has a sensor S for detecting the presence or absence of banknotes P.
The slit 23 for ₁ is formed in the circumferential direction so that even if one banknote P is wrapped around, it can be detected.

In addition, as shown in FIGS. 5 and 6, the cassette 1 is provided with a bill detection sensor S ₂ and a tape T both end detection sensor S _{3 which} are provided in the cassette 1 and the electromagnetic clutch 15. An electric system for operating the negative operation electromagnetic brake 22 and the like is configured by connecting a terminal 24 of the cassette 1 and a terminal 25 on the power source side.

As the tape T, a uniaxially stretched tape is used, and the surface thereof is preferably coated with silicon or the like so that jamming due to adhesion of sticky matter does not occur.

A carrying device 26 for picking up or taking out the bills P is provided on the main body of the apparatus so as to be located in front of the bill inlet / outlet 2 of the cassette 1. The transport device 26 is composed of a pair of upper and lower belts (or a row of rollers). The relationship between the transport speed of the transport device 26 and the speed of each part in the cassette 1 will be described later in the section of action.

Next, the operation of the above embodiment will be described. When the cassette 1 is set at a predetermined position of the apparatus main body, the pins 19, 19 of the drive shaft 18 on the apparatus main body side engage with the holes 20, 20 of the joint portion 21 facing the side surface of the cassette 1 to generate the driving force. It is in a state of being transmitted, the terminals 24 and 25 are connected, the electric system is connected, and the electromagnetic clutch 15 is turned on.
Becomes Further, when the cassette 1 is set at a predetermined position, the negative operation electromagnetic brake 22 is operated and the brake is released, and the second winding shaft 8 becomes rotatable. Therefore, if it is not set to the predetermined position, it will be in an inoperable state.

When the banknote P is stored in the cassette 1, as shown in FIGS. 1 and 5, the rotation of the drive shaft 18 causes the second winding shaft 8 to move in the clockwise direction (arrow direction) in FIG.
Rotate to. At this time, the rotation speed of the second winding shaft 8 is set so that the winding speed V ₁ of the tapes T and T is higher than the transport speed V ₂ of the transport device 26 by about 5 to 25%.
By acting to pull in the bill P, jamming of the bill is prevented.

At this time, the large-diameter gear 16 also rotates in the clockwise direction (arrow direction) and the small-diameter gears 14, 14 rotate in the counterclockwise direction (arrow direction). Cannot rotate counterclockwise due to the action of the second one-way clutches 17, 17 (allowing rotation only in the direction of the dotted arrow), and the action of the first one-way clutches 13, 13 (rotating only in the direction of the dotted arrow) As a result, only the small-diameter gears 14, 14 idle, and the first winding roller shaft 5 remains stopped.

By the second winding roller 7, the tapes T, T
When winding the tape, the first winding rollers 4 and 4 try to rotate in the counterclockwise direction due to the pulling action of the tape, but the first winding roller shaft 5 does not rotate in the counterclockwise direction. Tension is generated. Then, when the tension exceeds a predetermined value, a torque larger than a predetermined value is applied to the torque limiters 6 and 6, and the first winding rollers 4 and 4 are rotated. As a result, the tapes T, T are always given a tension corresponding to the set torque of the torque limiter.

When the storage of the bills P to be stored is completed in this way, the drive shaft 18 is stopped. At this time, the number of stored bills P is counted by the bill detecting sensor S ₂ . Then, every time there is a storage instruction for the banknote P, the above operation is repeated to store the banknote P.
When the bill P is stored and becomes full, the end of the tape T is detected by the sensor S ₃ , and further receipt is stopped.

When the banknote P is dispensed, as shown in FIGS. 2 and 6, the drive shaft 18 causes the second winding shaft 8 to rotate counterclockwise (in the direction of the arrow) in FIG. The take-up roller 7 is rotated counterclockwise (arrow direction) to rewind the tubs T, T. At the same time as the rewinding, the tabs 14, 14 meshing with the gears 16 on the shaft 8 are used to The first one-way clutch 13, 13 is attached to the take-up shaft 5, 5.
Rotation (transmitting the rotation only in the direction of the dotted arrow), the rotation is accelerated and transmitted, and the tapes T, T are fed at a speed faster than the speed at which the first take-up rollers 4, 4 rewind the tapes T, T. As a result, the tapes T and T are tensioned without being loosened. When the tension exceeds a predetermined value, the torque limiters 6 and 6 receive a torque larger than a predetermined value, causing slippage. As a result, tensions corresponding to the set torques of the torque limiters 6 and 6 are always applied to the tapes T and T.

In this way, as the tapes T, T are rewound from the second take-up roller 7, the tapes T,
The banknote P between T is thrown out from the banknote inlet / outlet 2,
Handed over to 5. When the number of banknotes P to be dispensed is detected by the banknote detection sensor S ₂ , the drive shaft 18 is stopped and the dispensing is completed. The above operation is repeated every time there is a withdrawal command for the banknote P, and the banknote P is withdrawn. However, when all the banknotes P have been withdrawn, the sensor S ₁ detects that there is no banknote and the banknote P is empty. Notify the device body that there is. At the time of this withdrawal, the speed V _{1 of the} tape T and the transport device 25
The relationship of speed V ₂ is V ₁ <V ₂ and V ₂ is 5 to 5
It is increased by about 25% and acts so as to pull out the banknote P.

FIG. 7 is an exemplary view when the motor 27 in the driving means is built in the cassette 1. The gear 28 rotated by the motor 17 installed in the cassette 1 is attached to the gear 16 on the second winding shaft 8. The bills P are accommodated and fed out by driving the motor 27 forward and backward. The configuration of the other parts is the same as that of FIG. 1, and therefore, the reference numerals corresponding to these are attached.

8A and 8B show the relationship between the length L, the width W and the height H of the cassette 1 of the embodiment shown in FIG. 1, but the length L and the height H are reduced. If there is a request to do so, the configuration as shown in FIGS. 9A and 9B can be adopted.

In this case, the first take-up rollers 4 and 4 are pivotally supported between the partition wall 10 in the cassette 1 and the second take-up roller 7, and the tape is provided at the inner corner of the cassette 1. Direction change members 29, 29 for making a U-turn of T, T are provided, and the tape T,
T runs around the first and second take-up rollers 4, 4, and 7. The direction changing members 29, 29 have inclined shoulders 29a, 29a on the left and right that are inclined at a required angle (for example, 45 °), and one of the inclined shoulders 29a is shown in FIG. To the other inclined shoulder 29a
The running direction of the tape T is reversed (U-turn) when the tape T is passed over.

By doing so, FIG. 9 (A), (B)
Although the width W of the cassette 1 increases as shown in FIG.
Is significantly reduced and can be significantly compacted as a whole.

In each of the above embodiments, the case where the two tapes T and T are used and the two first winding rollers 4 and 4 are used is shown. However, from the banknote inlet / outlet 2 to the second winding roller. If one side of the banknotes up to 7 is guided by another guide member and the banknote P is sandwiched between this guide member and one tape T to be conveyed, the first take-up roller 4, 4 is sufficient for one, and can be made more compact.

In the illustrated embodiment, the driving force is transmitted from the driving means to the second winding shaft 8, but the driving force is transmitted to the first winding shaft 5. Good. In this case, the first and second one-way clutches 13 and 17 and the torque limiter 6 may be provided on the second winding shaft 8 and the gear ratio may be changed accordingly.

[0032]

As described above, according to the present invention, only one motor is required as the driving means for driving the take-up roller, and therefore, the weight and space can be reduced, which is advantageous in terms of cost. In particular, since the tape is not subjected to an excessive tension, the tape is not broken, and both storing and feeding are performed only by forward / reverse driving of a single motor, so that the control is easy.
