Description

Description: TECHNICAL FIELD The present invention relates to a coin dispensing device for dispensing a required number of stored coins, and more specifically, to a coin dispensing operation by a belt mechanism. The present invention relates to a configured coin dispensing device.

[Conventional technology]

As is conventionally known, the coin processing device is configured to sort coins in a state in which coins of respective denominations are mixed for each denomination, and sort and store the coins in coin-type coin storage units. . The coins stored in the denomination-based coin storage unit by the coin processing device are then paid out from the denomination-based coin storage unit by the coin payout device as required by the required number of coins.

FIG. 14 and FIG. 15 show the configuration of a commonly used tube type coin dispensing device. As shown in these figures, the coin dispensing device 1 is provided with a coin storage tube 2 in which coins are stacked horizontally. A gap for one coin is formed between the bottom opening 2a of the tube 2 and the base 3,
The slider 4 can slide in the diametrical direction of the tube through the gap. The slider 4 is driven by a crank mechanism composed of an eccentric pin 6 attached to the output shaft of the motor 5 and a groove 4a formed at the slider front end with which the pin is engaged. When the slide 4 moves from the retracted position shown in Fig. 15 toward the tube side, the coin CN1 at the bottom of the tube is pushed laterally over the base and pushed out of the tube, forming a half-moon shaped cut on the base. It falls from the notch 3a. This operation is repeated and the required number of coins are paid out.

In such a conventional tube type coin dispensing device, in order to increase the dispensing capacity of coins, it is necessary to increase the height H of the coin storage tube to increase the number of coins to be stored. However, as the length of the tube increases, the size of the coin dispensing device, especially the length, increases accordingly, which in turn increases the length of the coin processing device in which such a device is incorporated.

As a coin dispensing device that can reduce the device height,
The one disclosed in Japanese Patent Publication No. 62-121672 is known. The coin payout device forms a coin holding section for receiving coins and a bottom surface of the coin holding section, and also has a coin conveying belt mechanism inclined upward in the coin conveying direction and a coin conveying belt mechanism. A coin reversing roller that faces the coin transport belt of the coin transport belt mechanism at a position near the downstream end in the transport direction at a constant interval and that rotates in a direction in which the coin transported by the coin transport belt is returned. Receive coins from the downstream end of the conveyor belt mechanism,
It has a discharging roller that conveys coins at a speed faster than the coin conveying speed of the coin conveying belt mechanism, and a photo sensor that detects coins that are fast-forwarded by the discharging rollers.

When paying out the coins in the coin holding section, the coin transport belt mechanism is driven. When the coin transport belt mechanism is driven, the coins on the coin transport belt are transported toward the payout side and reach the reversing roller arranged at the downstream end of the belt mechanism. Since the reverse rotation roller rotates in the direction of returning coins, when a plurality of coins are conveyed in an overlapping state, this roller returns the overlapping coins in the opposite direction. Therefore, coins can be conveyed one by one by properly setting the distance between the reverse rotation roller and the conveyance belt. In this way, the coins are paid out one by one by the conveyor belt mechanism and the reverse rotation roller.

[Problems to be solved by the invention]

However, the belt type coin dispensing device described in the above publication has the following problems.

That is, since the discharge roller rotates synchronously with the motor common to the conveyor belt, if the photosensor detects the last coin to be paid out, the drive of the motor is immediately stopped, so that the last paid coin is completely paid out. Since it is not possible to do so, the driving of the motor is stopped after a while, but during that time, the discharge roller may easily pull in the coins that follow. Even if the rotation drive is stopped, there is a disadvantage that the succeeding coins are erroneously dispensed due to inertia or the like.
In order to eliminate such an inconvenience, the discharging roller has to pay out the last paid-out coin and stop rotating before the subsequent coin sent out from under the reverse rotation roller reaches the discharging roller. For that purpose, it is necessary to make the conveying speed of the conveying belt as low as possible and set the peripheral speed of the discharge roller as high as possible. However, if the peripheral speed of the discharge roller is set as high as possible,
Since the inertia at the time of stopping becomes strong, it becomes difficult to stop rather than stopping,
There is a limit to speeding up the discharge roller. For this reason,
Although it is unavoidable to set the conveying speed of the conveying belt as low as possible, this lowers the coin dispensing speed and prolongs the dispensing waiting time. Therefore, the reliability (certainty) of the number of coins to be paid out and the payout performance (time) are in a trade-off.

Therefore, in view of the above problems, the present invention, while the coin storage unit only stores coins in an unaligned state,
It is an object of the present invention to provide a belt-type coin dispensing device that can simultaneously achieve certainty of the number of coins dispensed and improvement of the dispensing performance.

In order to solve the above problems, in the present invention, a coin storage belt for receiving a coin and a coin transport belt having a belt that forms the bottom surface of the coin storage portion and is inclined upward in the coin transport direction. A mechanism, a reverse feed roller that faces the belt at a position near a downstream side end of the belt in the transport direction at a constant interval, and rotates in a direction to return coins transported by the belt; In a belt type coin dispensing device having a fast-forward mechanism for receiving coins from the downstream end of the belt and for transporting coins at a speed faster than the coin transport speed of the belt, and a coin sensor for detecting coins fast-forwarded by the fast-forward mechanism. , The coin transport belt mechanism and the fast-forward mechanism are driven by driving means of different systems, and the last dispensed coin is detected by the coin sensor. When knowledge immediately stops driving the coin conveying belt mechanism, characterized in that stops driving of said rapid traverse mechanism and then delayed.

In such a basic configuration, the coin transport belt mechanism includes a first coin transport belt located upstream in the coin transport direction and a second coin transport belt located downstream. The inclination of the second coin transport belt is set to be larger than the inclination of the first coin transport belt, and the fast-forward mechanism receives coins from the downstream end of the second coin transport belt, and the second coin transport belt receives the coin. It is possible to adopt a configuration in which coins are conveyed at a speed faster than the coin conveying speed by the coin conveying belt.

Further, as a belt type coin dispensing device corresponding to a denomination, the coin storage section includes a plurality of denomination-based coin storage sections, the coin transport belt mechanism, the reverse feed roller,
The fast-forwarding mechanism and the coin sensor are respectively arranged in the coin-type coin storage portions, and the drive means of the plurality of fast-forwarding mechanisms can be a common drive means.

[Action]

In the present invention, since the drive system of the coin transport belt mechanism and the drive system of the fast-forward mechanism are separate systems, the drive system on the side of the coin transport belt mechanism can be stopped immediately when the coin sensor detects the last coin to be paid out. , The inconvenience that the subsequent coin fast-forward mechanism is accidentally paid out does not occur. Further, since the driving of the fast-forwarding mechanism is delayed and stopped, the last dispensed coin detected by the coin sensor can be reliably dispensed without staying in the fast-forwarding mechanism. In other words, even if the transfer speed of the coin transfer belt mechanism is increased, if the transfer speed of the fast-forward mechanism is higher than that, the distance between the last dispensed coin and the succeeding coin will be increased. If the drive system of the coin transport belt mechanism is immediately stopped when the last payout coin is detected by the sensor, the subsequent coins are not delivered from the coin transport belt mechanism. In other words, it is possible to realize an increase in the transfer speed of the coin transfer belt mechanism without causing an incorrect payout of subsequent coins, and it is possible to improve the coin payout performance (speed).

Further, in the belt type coin dispensing device in which the first coin transport belt and the second coin transport belt are connected, the coin is first transported by the first coin transport belt having a gentle slope and then the steep slope is provided next. It is carried by the second coin carrying belt. While being conveyed by the steeply inclined second coin conveying belt, coins conveyed in an overlapping state are gradually separated, and coins are overlapped by the reverse feeding roller arranged at the downstream end (two-layer feeding). Are eliminated. Therefore, the coins are surely paid out one by one, and the jamming of coins at the mouth of the reverse feed roller can be prevented. Moreover, since the volume of the coin storage portion increases, the number of coins stored increases.

Furthermore, in the belt type coin dispensing device of the present invention corresponding to the denomination, the coin storing section is provided with a plurality of coin storing sections of different denominations, and the driving means of the plurality of fast-forwarding mechanisms for different denominations are commonly driven. As a means, when the common driving means is stopped after the last denomination denomination coins are completely paid out, the plurality of fast-forwarding mechanisms are simultaneously driven and stopped. It is not necessary to provide a drive means for each fast-forward mechanism for each denomination, even though a coin storage section for each denomination is provided and the drive system for the fast-forward mechanism and the coin transport belt mechanism are separate systems. The space can be greatly reduced and the size can be reduced.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

First Embodiment FIGS. 1 to 3 show a belt type coin dispensing device according to a first embodiment of the present invention. In the belt type coin dispensing device 10 shown in the figure, 11 and 12 are device side plates arranged in parallel, and a front partition plate 13 and a rear partition plate 14 are mounted between them. These dividers 1
A coin transport belt mechanism 15 that is inclined upward toward the front partition plate 13 is disposed between the side plates 11 and 12 on the lower side of the plates 3 and 14. These side plates 11, 12, partition plate 13,
The side surface of the coin storage portion 16 having a rectangular cross section is formed by 14,
The bottom surface of the storage unit 16 is formed by the coin transport belt mechanism 15. The distance between the side plates 11 and 12 corresponds to the diameter of coins to be stored and is set slightly larger than the diameter.

At a position between the lower end 13a of the front partition plate 13 and the coin transport belt mechanism 15, a reverse feed roller 17 is attached between the side plates. In front of the front end of the coin transport belt mechanism 15, a horizontal coin guide 18 for receiving the coins CN transported by this belt mechanism is arranged, and a fast-forward roller 19 is arranged so as to face the guide 18. . This fast-forwarding roller also transports coins at a speed faster than that of the coin transport belt mechanism 15. An optical coin sensor 21 is arranged on the coin delivery side. And both side plates 13, 14
The portion on the front side of the fast-forwarding roller 19 whose both sides are defined by is the coin payout outlet 22.

The above coin transport belt mechanism 15 includes a drive side pulley 151 and a driven side pulley 152 which are rotatably supported between the side plates,
The coin transport belt 153 is stretched between them, and a motor 154 attached to the outer surface of the one side plate 12. The motor 154 is fixed to the side surface 12 by a mounting plate 155, and its output shaft 154a has a rotation shaft 151a of a driving pulley 515 through a transmission mechanism 154b including a belt and a pulley.
It is connected to.

As can be seen from FIG. 1 and FIG. 3, a gear 23 is fixed to a portion of the rotary shaft 151a of the drive pulley 151 protruding outward from the side plate 11, and this gear 23
Is an idle gear rotatably supported on the outer surface of the side plate 11.
The side plate 1 on the rotary shaft 17a of the reverse feed roller 17 via 24
It is connected to a gear 25 that is fixed to a portion protruding from 1 to the outside. In this way, the motor 154 serves as a drive source for the reverse feed roller 17. On the other hand, the drive source of the fast-forwarding roller 19 is different, and as shown in FIG. 3, the fast-forwarding roller 19 has a gear 191 and an idle gear 192, which are fixed to the rotation shaft 19a thereof, and are not shown. It is connected to the drive source.

The operation of the belt-type coin dispensing device 10 of this example configured as described above will be described. First, coins are stored in the coin storage portion 16 from the upper opening thereof. When paying out coins, the motor 154
Is driven to operate the coin transport belt mechanism 15, and the coin transport belt 153 starts moving toward the coin payout outlet 22 side as indicated by the arrow. As a result, the coin CN on the belt 153 is conveyed toward the reverse feed roller 17 side.

This reverse feed roller 17 is an idle gear as described above.
Since it is connected to the drive pulley 151 via 24, it rotates in the same direction as the drive pulley 151. For this reason,
The belt 153 rotates in a direction in which coins conveyed by the belt 153 are pushed back. Therefore, as shown in FIG. 2, the coins conveyed in the state of being overlapped toward the gripping side of the reverse feed roller 17 have the upper coin fed backward and only the lower one coin. After passing through the reverse feed roller 17, it is conveyed to the fast feed roller 19 side.

The coins transferred from the coin transport belt 153 to the fast-forwarding roller 19 side are transferred at a higher speed than the conventional coin payout outlet 22.
Is transported toward. Therefore, the coins passed through the reverse feed roller 17 and fed out one by one are fast forwarded by the fast forward roller, so that the coins are fed out one by one from the delivery side at a constant interval. The coins thus sent out at regular intervals are detected by the optical sensor 21 and then paid out from the coin payout opening 21.

Here, the number of coins paid out from the output of the optical sensor 21 is counted, and after the required number of coins are paid out, the driving of each unit is stopped. This stopping operation in this example is as follows. First, when the sensor 21 detects the last coin to be paid out, the coin transport belt mechanism 15 immediately
To stop. Therefore, the reverse feed roller 17 also stops. However, the fast-forwarding roller 19 continues to rotate until the final payout coin has passed through it.

In this way, the coin transport belt mechanism 15 and the fast feed roller 19
Since the drive system of each is a separate system, the drive system of the coin transport belt mechanism 15 side can be stopped immediately when the last coin to be paid out is detected by the optical sensor 21, so that the subsequent coin fast-feed roller 19 The inconvenience of being paid out by mistake does not occur. Further, since the driving of the fast-forwarding roller 19 is delayed and stopped, the final dispensing coin detected by the optical sensor 21 can be reliably dispensed without staying at the fast-forwarding roller 19. That is, even if the transfer speed of the coin transfer belt mechanism 15 is increased, if the transfer speed of the fast-forward roller 19 is higher than that, the interval between the last payout coin and the succeeding coin will be expanded. If the drive system of the coin transport belt mechanism 15 is immediately stopped when the final payout coin is detected by the optical sensor 21, subsequent coins are not delivered from the coin transport belt mechanism 15. In other words, the coin transport belt mechanism 15 does not cause the subsequent coins to be dispensed by mistake.
It is possible to increase the transfer speed, and the coin payout performance (speed)
Can be improved.

As described above, the belt-type coin dispensing device 10 of this example
In the above, a configuration is adopted in which the coin storage portion is partitioned and formed by the side plate, the partition plate, and the coin transport belt mechanism, and the coin dispensing operation is performed by the coin transport belt. Therefore, as compared with the conventional tube type coin dispensing device, it is possible to store a larger number of coins without making the height dimension (H of FIG. 2) so large. Further, since the reverse feed roller is arranged, the coins can be reliably conveyed by the conveyor belt one by one. Furthermore, since the fast-forwarding roller is arranged, the coins to be dispensed can be fed at a predetermined interval, and the coins to be dispensed can be reliably detected.

Second Embodiment FIGS. 4 and 5 show the overall structure of a belt type coin dispensing device according to a second embodiment of the present invention. The belt type coin dispensing device 30 of the present example is also basically the same as the above example, but is mainly different in that the coin conveying belt mechanism is composed of two coin conveying belts having different inclinations.

Explaining in detail, the coin storage unit in the device 30 of this example
36 is partitioned and formed by a pair of side plates 31, 32, a partition plate 34, and a coin transport belt mechanism 35. Where the side plate
The interval between 31 and 32 is set similarly to the first embodiment.
The coin transport belt mechanism 35 includes a first coin transport belt mechanism 46, which is installed on the partition plate 34 side and has a gentle slope, and a second steep slope, which is connected to the coin transport side of the coin transport belt mechanism. It is composed of a coin transport belt mechanism 47. First
The coin transport belt mechanism 46 defines the bottom surface of the coin storage portion 36, and the second coin transport belt mechanism 47 defines the front surface of the coin storage portion 36.

A reverse feed roller 37 is arranged on the upper end side of the second coin transport belt mechanism 47. Further, a coin fast-forwarding mechanism 39 is arranged so as to face the coin guide 38 that receives coins carried out from the upper end side of the second coin transport belt mechanism 47. An optical sensor 41 for detecting coins passing therethrough is arranged on the coin delivery side of the coin fast-forwarding mechanism 39. Further, on the coin delivery side of the coin fast-forwarding mechanism 39, a coin payout outlet 42 is defined by the coin guide 38, the cover 48 arranged above the coin guide 38 and both sides 31, 32.

The above-mentioned first coin transport belt mechanism 46 is a drive-side pulley.
461, a driven pulley 462, a tension pulley 463, and a guide pulley 464, on which a coin transport belt 465 is stretched. As shown in FIG. 6, the drive source of the belt mechanism 46 is a motor 466 mounted between the side plates 31 and 32 at the lower position of the belt mechanism 46. Similarly, the second coin transport belt mechanism 47 includes a drive side pulley 471, a driven side pulley 472, and a coin transport belt 473 stretched over these.
And the drive source thereof is the above-mentioned motor 466. Further, coin engaging projections 47a are formed on the surface of the coin transport belt 473 on the second side at intervals wider than the diameter of the coin to be transported in the transport direction.

Here, a pair of vertical plates 49, 49 is provided above the lower end side of the first coin transport belt mechanism and includes a partition plate 34 and a side plate 3.
Installed between 1 and 32. These vertical plates 49
From the center position of the partition plate 34 toward the coin transport direction, approximately 45
It is arranged in a state of spreading in the direction of degree. Further, the lower end surfaces 49a of these vertical plates 49 are substantially the same inclined surfaces as the coin transport belt 465, and the height from the belt surface of these inclined surfaces 49a is higher than the radius of the coin. Is set.

The driving force transmission system of each coin transport belt mechanism will be described with reference to FIG. The output shaft of the motor 466, which is a drive source, is connected to a rotating shaft 466a rotatably supported by both side plates via a pair of bevel gears. A gear 466b is fixed to the rotation shaft 466a on the outside of the side plate 31, and the gear 466b is fixed to the rotation shaft 461a of the drive pulley 461 which is an element of the first coin transport belt mechanism. It is in mesh. This gear 461b is also the idle gear 461c.
The drive-side pulley 471, which is an element of the second coin transport belt mechanism, is connected to the gear 471b fixed to the rotating shaft 471a via the. On the other hand, a gear 472b is fixed to the rotation shaft 472a of the driven pulley 472 of the second coin transport belt mechanism,
The gear 472b is connected to a gear 37b fixed to the fast-feed roller rotating shaft 37a via an idle gear 472c.

Next, the structure of the fast-forwarding mechanism 39 will be described with reference to FIG. The mechanism 39 has a drive pulley 391 and a driven pulley 392, and a fast-forward belt 393 stretched around these. The rotary shaft 391a of the drive pulley 391 is
It is rotatably supported by 1, 32 and one side plate 3
A gear 391b is fixed to a portion protruding from 1 to the outside, and the gear 391b is attached to the outside of the side plate 31 to serve as a motor 394.
Meshes with the gear 394a fixed to the output shaft of the. on the other hand,
On the driven pulley 392 side, a rotation shaft 392a is rotatably supported by the tips of a pair of tension arms 395, 395. These tension arms are fixed at their base ends to a shaft 397 rotatably supported by the side plates 31 and 32. The rotation of the shaft 397 is restricted by a stop member (not shown) in a state where elastic torque is applied counterclockwise toward the drawing. In this example, the distance between the belt 393 wound around the pulley 392 supported by the tension arm and the coin guide 38 is set to be slightly smaller than the thickness of the coin.

The operation of the belt type coin dispensing device 30 of this example will be described. The coins thrown into the coin storage unit 36 define the bottom surface thereof, and therefore fall on the coin transport belt 465 on the first side and accumulate there. At the time of coin dispensing, both coin transport belt mechanisms start driving at the same time. The coins are first conveyed by the first side coin conveying belt 465 with a gentle inclination to the second side coin conveying belt 473, and this belt 4
Delivered to 73. This second side coin transport belt 473
Has a steep slope, but the coin engaging projections formed on its surface
The 473a reliably receives the coin from the first side and conveys the coin toward the upper coin payout outlet 42 side. On the upper end side of the coin transport belt 473 on the second side, as in the case of the first embodiment described above, the reverse feed roller 37 and the fast feed mechanism are provided.
39 are arranged, through which coins are dispensed from the coin dispensing outlet 42 at regular intervals one by one.

Here, the coins inserted into the coin storage unit 36 remain standing on the coin transport belt 465 on the first side, which is the bottom surface, and the coins in this state are aligned in the width direction of the belt. Then, even if the belt moves, there is a risk that the coins will only roll on the belt and will not be conveyed forward. However, in the present example, the first side conveyor belt 465 is inclined and the pair of vertical plates 49, 49 is arranged at the rear end side thereof to avoid such a harmful effect.

That is, as shown in FIG. 5, coins that have fallen while standing on the coin transport belt 465 on the first side rolls downward on this belt and reaches the lower end (rear end) thereof. Arrive FIG. 9 shows a group of coins arranged in the width direction of the belt in this manner and in a so-called bale state. When the coin transport belt 465 starts moving in such a state, the coin group is guided by the pair of vertical plates 49, 49, and the side facing the transport direction is directed outward as indicated by the arrow in FIG. And as a result, the lower side as a whole has a posture inclined outward. As shown in FIG. 5, the lower end surfaces 49a of these vertical plates 49 are at the center position of the coin (center of gravity position).
Since it is located above the coin, the coin thus inclined falls on the belt. In this way, the bale state of coins is avoided, and coins are transported smoothly.

Next, in the fast-forward mechanism 39 of this example, the pulley 392 is supported by the tension arm 395 as described above. Therefore, the coin that reaches here is held between the belt 393 and the coin guide 38 of the rapid feed mechanism under the action of an appropriate pressing force, so that the coin can be rapidly forwarded.

The drive stop operation of each part will be described with reference to FIGS. 8 (A) to 8 (C). As shown in FIG. 8 (A), the second
The coin CN conveyed to the side of the fast-forward mechanism 39 by the coin transport belt 473 on the side of is fastened to the fast-forward mechanism 39 as shown in FIG. It is conveyed to the payout opening 42 side. Fast-forward mechanism
The tip of the coin CN held in 39 is the optical axis 41 of the sensor 41.
This sensor is in the coin detection state when a is blocked, and thereafter, when the coin CN has passed the optical axis 41a of the sensor, the sensor returns to the non-detection state of coins, and the change in the sensor output causes , It is detected that one coin has passed. As shown in FIG. 8 (C), such a detecting operation can be performed reliably because it can be performed at intervals between the coin CN and the succeeding coin CN 'by the fast-forwarding mechanism 39. When the above coin CN is the last coin to be paid out, the time when this coin CN is detected by the sensor 41, that is, FIG. 8 (B).
At the time point indicated by, the first and second coin transport belt mechanisms and the reverse feed roller stop. After this, only the fast-forward mechanism 39 is put into operation, and the coin CN gripped is shown in FIG. 8 (C).
As shown in, the fast-forwarding mechanism 39 stops after it is carried out from the fast-forwarding mechanism 39. For this reason, as described in the first embodiment, the coins of
The transfer speed of the first and second coin transfer belt mechanisms 46, 47 can be increased, and the coin dispensing performance (speed) can be improved.

As described above, in this example, the coin transport belt mechanism is configured by the first mechanism having a gentle slope and the second mechanism having a steep slope. Therefore, the coin storage capacity can be increased as compared with the case of the first embodiment described above. That is, in the case of the first embodiment, in order to increase the coin storage capacity while keeping the height as it is, it is necessary to increase the length (dimension L in FIG. 2). However, in this case, since the gradient of the coin transport belt is constant, the space below it is wasted, which is not preferable. On the other hand, in this example, since the inclination of the first coin transport belt mechanism is set to be gentle, even if the length of the device is increased in order to increase the coin storage capacity, it is useless. It has less space and is therefore suitable for increasing coin storage capacity. Further, the device of this example is particularly suitable for the case where the position of the coin payout outlet 42 must be arranged above.

Further, in this example, it is expected that the coins in the overlapping state will gradually slide down while the coins are conveyed by the coin conveying belt in the second coin conveying belt mechanism having a steep slope. It is preferable that a large number of coins are simultaneously conveyed to the gripping side, so that the occurrence of jamming of coins at this portion is avoided.

FIG. 10 shows a modification of the fast-forward mechanism in this example. In the illustrated example, the drive pulley 391 is
The driven pulley 392 is installed on the side opposite to the tension arms 395, 395. With this change, the motor 394, which is the drive source of the drive pulley 391, is also installed near the drive pulley. is there.

Third Embodiment Next, FIGS. 11 to 13 show an apparatus 50 provided with a plurality of belt type coin dispensing devices 30 according to the second embodiment. Since the device of this example basically has a configuration in which the devices of the second embodiment described above are arranged side by side,
In these figures, only the portion of the coin fast-forwarding mechanism is shown, and the same reference numerals are given to the components corresponding to the above-mentioned second embodiment, and the description thereof will be omitted. .

In the apparatus 50 of this example, as best seen from FIG. 11, the single motor 394 is used as the drive source of the plurality of fast-forwarding mechanisms 39, 39 ... By doing so, it is possible to achieve a reduction in the number of drive devices and a corresponding reduction in the installation space as compared with the case where drive sources are arranged corresponding to each mechanism, which is preferable.

In the device 50 of this example, the drive sources of the coin transport belt mechanisms 35, 35 ... Are separate from each other.
Therefore, the coin transport belt mechanisms 35, 35 ... Are driven and controlled separately, and all the fast-forwarding mechanisms 39, 39.

According to the apparatus of this example, coins of each denomination can be stored and paid out. Incidentally, by arranging a plurality of the devices 10 of the above-described first embodiment as in the present example, it is of course possible to configure a storage / delivery device for coins of a plurality of denominations.

Particularly, in this example, since the driving means of the coin transport belt mechanism 35 and the driving means of the fast-forward mechanism 39 are independent in the coin dispensing device for each denomination, the coin sensor detects the last coin to be dispensed. Then, the driving means on the coin transport belt mechanism side can be stopped immediately. Therefore, there is no inconvenience that the subsequent coins are drawn into the fast-forwarding mechanism 39, so that the subsequent coins are not erroneously dispensed.
Therefore, the coin transport belt mechanism 35 can be speeded up,
The payout performance can be improved.

〔The invention's effect〕

As described above, the belt type coin dispensing device according to the present invention has the following special effects.

Since the coin transport belt mechanism and the fast-forward mechanism have different drive systems, the drive system on the side of the coin transport belt mechanism can be stopped immediately when the coin sensor detects the last coin to be dispensed. There is no inconvenience that the fast-forward mechanism accidentally pays out. Further, since the driving of the fast-forwarding mechanism is delayed and stopped, the last dispensed coin detected by the coin sensor can be reliably dispensed without staying in the fast-forwarding mechanism. Therefore, while the coin storage unit only stores coins that are in a misaligned state, it is possible to increase the transfer speed of the coin transfer belt mechanism without causing the wrong transfer of subsequent coins, and the coin transfer performance is improved. (speed)
It is possible to provide a belt-type coin dispensing device with improved performance.

In the belt type coin dispensing device in which the first coin transport belt and the second coin transport belt are connected, it is possible to prevent the jamming of coins at the mouth of the reverse feed roller. In addition, since the volume of the coin storage portion increases, the number of coins stored increases.

In the belt type coin payout device corresponding to the denomination, the coin storage portion is provided with a plurality of denomination type coin storage portions, and the drive means of the plurality of fast-forwarding mechanisms for different denominations are common drive means. For this reason, it is not necessary to provide a drive unit for each denomination, even though a coin storage unit for each denomination is provided and the drive system for the fast-forward mechanism and the coin transport belt mechanism are separate systems. The installation space can be greatly reduced and the size can be reduced.
