Abstract

PURPOSE:To prevent a remaining coin from being erroneously detected due to dust or the like stuck to the coin by forming a transaction tray by a light- transmissive material and detecting the existence of coin remaining in the tray by a remaining coin detecting means through the light-transmissive material. CONSTITUTION:The light-transmissive material of the transaction tray 4 and a light receiving element 21 are arranged in the irradiating direction of light from a light emitting element 20 and the element 21 is fixed to a fixing member 22 fixed to the bottom position of the outside of the tray 4 so that its light receiving part is oriented to the side of the element 20. The element 20 irradiates over a prescribed range and three light receiving elements are arranged in the light irradiating direction correspondingly to one light emitting element 20. Since plural light emitting elements 20 and light receiving elements 21 corresponding to the elements 20 are provided, remaining coins in the tray 4 can be completely detected. Since the tray 4 is unitedly molded by transparent resin (light-transmissive material) or the like, dust or the like is not collected and remaining coin detecting means 19 does not detect erroneously the remaing coin.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a residual coin detecting device for detecting residual coins on a trading plate of a circulation type coin depositing / dispensing machine in which coins are inserted or removed.

[0002]

2. Description of the Related Art As a conventional circulation type coin depositing / dispensing machine, there is one disclosed in Japanese Patent Application Laid-Open No. 61-253595. This is because when coins are manually inserted into the trading plate provided in the fuselage from the trading port at the time of deposit,
The authenticity of the deposited coins, the denomination, etc. are discriminated, and the acceptable coins are replenished as coins for withdrawal to the denomination storing section for each denomination. The coin corresponding to the amount of money is fed from the denomination-based storage portion to the trading plate, and the coin fed to the trading plate is manually taken out. In addition, when the coins that are manually inserted from the trading port at the time of deposit are taken into the machine body, the transaction plate of this type of circulating coin depositing / dispensing machine checks whether or not the coins inserted in the transaction plate remain. In order to detect or to detect whether all the coins delivered to the trading plate from the coin storage unit at the time of withdrawal were taken out manually, multiple detection sensors to detect residual coins on the trading plate are provided on the trading plate. By providing the coins, misjudgment such as counting of coins caused by remaining coins can be prevented.

[0003]

Further, as a conventional detection sensor of this type, as disclosed in Japanese Utility Model Laid-Open No. 164579/1989, a light beam emitted by a light emitting element at a predetermined angle hits an object to be detected. A reflection type sensor is used in which a light receiving element receives a light beam reflected by a light receiving element to detect an object to be detected. However, since the positions of the light emitting element and the light receiving element are fixed in this reflective sensor, the angle of the light beam emitted by the light receiving element is set in advance, except that the residual coin is located at a predetermined position. No matter how the light emitting element irradiates residual coins, the direction of the reflected light beam is different from the direction of the light receiving element, and the light receiving element cannot receive this, and it is mistaken that there is no coin remaining. There was a problem to detect.

In order to detect the coins remaining on the trading plate, a plurality of small holes are provided at the bottom of the trading plate, and both elements are inserted into the small holes. Whenever the number of coins increases, dust or dirt that accumulates on the coins accumulates in the small holes, which blocks the light beam and prevents the light receiving element from receiving this light beam, even though no coin remains. However, there was a problem in that it was judged that it remained, leading to malfunction of this machine. Also, when the withdrawal coins that have been discharged from the coin-type storage unit to the trading plate at the time of withdrawal are taken out, the inside of the trading plate is dark. There was a problem that it was difficult to confirm.

The present invention has been made in view of the above problems, and solves the above problems in the conventional circulation type coin depositing / dispensing machine, widens the detection area of residual coins, and inserts coins from the trading port. To provide a coin residual detection device in a circulation type coin depositing / dispensing machine capable of preventing erroneous detection due to dust and dirt adhering to the inside of the coin, facilitating insertion and removal of coins, and performing stable coin depositing and dispensing operation The purpose is to

[0006]

[Means for Solving the Problems] In order to achieve the above object, in the first aspect of the present invention, the coins inserted into a transaction counter are judged to be true or false and the denomination is determined, and the coins that are judged to be acceptable are selected. In a circulation type coin depositing / dispensing machine that stores in a coin type storing unit and pays out coins discharged from the coin type storing unit to a trading port based on a withdrawal command, the coin is dispensed inside the machine in the vicinity of the trading port. At least a part of the trading plate, which is movably provided and capable of accepting incoming and outgoing coins, is formed of a transparent material, and the presence or absence of coins is optically detected through the part of the trading plate formed of the transparent material. The residual coin detecting means for detecting selectively is provided in the vicinity of the trading plate.

[0007] In the second invention, the residual coin detecting means emits light through a light emitting element which is arranged in the vicinity of the trading plate and emits a light beam, and a portion of the trading plate which is formed by a translucent material. And a light receiving element provided at a position capable of receiving a light beam emitted by the element, and a plurality of residual coin detecting means are arranged in parallel.

In the third invention, the light emitting element is arranged above the trading plate and emits visible light.

[0009]

In the first aspect of the invention, when a coin is inserted into the transaction plate where coins are inserted or removed at the transaction port, the transaction plate is rotated and the coin inserted into the transaction plate is inserted into the fuselage. After being taken in, it is transferred in the direction of the storing section by denomination, while
The trading plate that has released the coins returns to the standby position. At this time, since the light beam that passes through the translucent portion of the trading dish is received by the residual coin detecting means, if the residual coin detecting means does not receive the light beam, it is assumed that coins remain on the trading dish. The coin discharging operation on the trading plate can be performed again. Further, at the time of withdrawal, the coins remaining in the transaction plate are discharged by the residual coin detecting means even after the coins withdrawn from the coin storing unit are discharged into the transaction plate and the coin is taken out manually. The presence or absence of the coin can be detected, and when a remaining coin is detected, the trading tray can be rotated to forget the remaining coin and take it as a coin into the machine body.

In the second invention, when the light receiving element receives the light beam of the light emitting element of the residual coin detecting means through the light transmitting portion of the trading plate, it is determined that there is no coin on the trading plate, and the light receiving element is also present. If it is not possible to detect the light beam of the light emitting element, it is determined that the coins remain on the trading plate, whereby the trading plate rotates, and the coins in the trading plate are discharged downward,
When the trading plate returns to the standby position, in the trading plate,
It is possible to detect whether or not there are residual coins that have not been delivered to the denomination-specific storage unit. Furthermore, even when a withdrawal is made, the trading plate receives coins similarly discharged from the denomination-specific storage unit.
After being manually taken out, it is possible to detect whether or not there are residual coins that have not been taken out in the trading plate.

According to the third aspect of the present invention, the light of the light emitting element that constantly emits light is made visible light, so that the trading plate can be brightened, and coins can be inserted or taken out easily.

After the deposit is once counted by the deposit discriminating unit, it is immediately transported by the transport passage 9 through the reject passage 8 and further collected in the forget-to-remove box 13 through the rotating disk 11 and the transport passage 18. Further, the coins rejected when the coins dispensed from the denomination storing unit 12 are dispensed to the transaction dish 4, are stored in the dispense reject box 14 through the transport path 18. Further, a mounting recovery safe 1 for storing coins loaded in the coin storing unit and storing coins collected from the overflow storing unit 10.
6 is configured to be detachable from the inside of the machine body 1 at the open position of the rotating disk 17.

Further, referring to FIG. 2, a detailed description will be given of a residual coin detecting device which is an embodiment of the present invention. A transaction dish having a U-shaped cross section provided obliquely below the transaction port 2. Reference numeral 4 denotes a semicircular side wall of which is fixed to a support member 24, and the support member 24 is rotatably supported at its center portion by a shaft 23 fixed to the machine body 1. It should be noted that, in the trading plate 4, a position in which the receiving port faces vertically upward as shown in FIG. 2 is a standby position. A fixed member 28 interlocking with a support member 24 is rotatably supported on the shaft 23, and one end of an arm 25 is rotatably supported on the fixed member 28 via a shaft 29. Furthermore, the arm 2
At the other end of 5, a fixing member 2 is formed in a V shape via a shaft 30.
One end of 6 is rotatably supported, and the other end is fixed to the side surface of the gear 27 by pins 31a and 31b. Further, since the gear 27 is interlocked with a drive unit (not shown), when the gear 27 is driven clockwise, the fixing member 26,
The support member 24 is rotated clockwise about the shaft 23 via the shaft 30, the arm 25, the shaft 29, and the fixing member 28, and the trading tray 4 supported by the support member 24 is also rotated in the same direction. The drive unit (not shown) is driven until the receptacle of the trading plate 4 is positioned in the vertical direction. As a result, the coins inserted into the trading plate 4 from the trading port 2 at the time of deposit are discharged onto the rotating disk 5 located below as the trading plate 4 rotates, as shown in FIG.

Next, after depositing coins into the trading plate 4 at the time of depositing and discharging the coins onto the rotary disk 5, or at the time of dispensing, the coins delivered to the trading plate 4 from the coin-type storing unit 12 were manually taken out. Explaining the residual coin detecting means 19 for detecting the presence or absence of residual coins in the subsequent trading tray 4, a plurality of light emitting elements 20 for irradiating light rays are arranged above the trading tray 4 in the machine body 1. A sensor using this type of light emitting and light receiving element uses an invisible light ray (for example, infrared ray) as a light ray to be applied. However, visible light is used as the light emitted from the light emitting element 20, and the visible light is applied to the trading plate 4
Since the vicinity of the trading port can be brightened by irradiating it upwards, it becomes possible to reliably insert and withdraw coins when depositing and withdrawing. Further, the light emitting element 20 always emits light when the power source of the device is ON.

The light transmissive material of the transaction dish 4 and the light receiving element 21 are arranged in the irradiation direction of the light beam emitted by the light emitting element 20. The light receiving element 21 is attached to a fixing member 22 fixed to a bottom position outside the trading plate 4 such that the light receiving portion faces the light emitting element 20 side. The light emitting element 20 irradiates a light beam over a predetermined range, and three light receiving elements 21 are provided for one light emitting element 20 on the irradiation direction line of the light beam. Therefore, the plurality of light emitting elements 2
By providing 0 and a light receiving element 21 corresponding thereto, it is possible to prevent leakage in detection of residual coins on the trading dish 4, and even one of the light receiving elements 21 that receives this light beam can receive the light beam. When it is not possible, the coin remains on the trading plate 4.

Therefore, conventionally, it is necessary to provide a considerable number of small holes in the bottom of the trading plate 4 for penetrating the light rays emitted from the light emitting element 20, and dusts attached to coins each time the number of times of use increases. If dust or dust accumulates in one of the small holes, the light beam may be blocked, leading to malfunction of the machine body 1. However, in the embodiment of the present invention, the small hole is eliminated.
Since the transaction dish 4 is integrally molded with a transparent resin (translucent material) or the like, dust and dirt do not collect, and the light beam emitted by the light emitting element 20 can also be transmitted therethrough. There is no concern that the detection means 19 will erroneously detect.

In the conventional reflection type sensor, the angle at which the light emitting element emits the light beam and the angle at which the light receiving element receives the light beam are preset. That is, in order for the light rays emitted by the light emitting element to be reflected by the remaining coins and for the light receiving elements to receive the reflected light rays, the residual coins must be located at a set point, for example, the residual coins Even if it hits the light beam emitted by the light emitting element at the position where the one point is removed, the light receiving element cannot receive it because the reflection direction of the light beam shifts, and even if coins actually remain, this is detected. Although it cannot be done, in the embodiment of the present invention, if a residual coin is located on the line connecting the light emitting element 20 and the light receiving element 21, it is detected. By providing a plurality of coin detecting means 19, it is possible to prevent the remaining coins on the trading plate from being leaked.

When the light-emitting element 20 arranged above the trading plate 4 is located at a position where it interferes with the operation of other mechanisms in the machine, the light-receiving element 2 for receiving light rays inside the machine body 1 of the shutter 3 is used.
For example, a mirror member that reflects in one direction may be provided. That is, the light beam emitted by the light emitting element 20 is reflected and emitted in the direction of the light receiving element 21.
It is not necessary to dispose on a line connecting 0 and the light receiving element 21, and the position where the light emitting element 20 is disposed can be changed according to each condition.

Next, the operation of the trading plate 4 will be described.
At the time of depositing, it is manually inserted into the trading tray 4 from the trading port 2, and after a predetermined time has elapsed, the shutter 3 is closed and the drive unit (not shown) is driven to rotate the gear 27 clockwise as viewed from FIG. And the trading plate 4 is the shaft 2 in the clockwise direction.
It will rotate about 3. When the trading plate 4 is rotated to a predetermined position, the inserted coins are discharged to the lower rotary disk 5, and after a predetermined time elapses, a driving unit (not shown) is driven in the reverse direction again, and the gear 27 is rotated counterclockwise. While rotating, the trading tray 4 is also moved to the standby position shown in FIG.

When the trading tray 4 moves to the standby position, the light receiving element 21 can receive the light beam emitted by the light emitting element 20 of the residual coin detecting means 19 at the standby position. Therefore, if even one of the plurality of light receiving elements 21 does not receive the light beam emitted from the light emitting element 20 at the standby position, it is assumed that the coin remains on the transaction dish 4 and the above-mentioned drive unit (not shown). Is driven to eject coins to the rotary disk 5. Further, when all the light receiving elements 21 receive the emitted light, it is assumed that there is no coin on the transaction dish 4, and the rotary disc 5 is driven to continue the deposit operation.

Further, at the time of withdrawal of money, the money type storage unit 12
The coins delivered from the transaction tray 4 to the transaction dish 4 are detected by the residual coin detecting means 19 and the shutter 3 is opened to be manually removed from the transaction port 2. When a predetermined time has elapsed after the shutter 3 was opened, the shutter 3 is closed, and the residual coin detecting means 19 detects the presence or absence of coins remaining on the trading plate 4 as described above, and when the residual coins are detected, The remaining coins are transferred to the forgotten collection box 13, and if no remaining coins are detected, the dispensing operation is completed.

When the shutter 3 is made of a transparent resin or the like, the inside of the trading dish 4 is illuminated by the light emitting element 20 of the residual coin detecting means 19, so that the shutter 3
Even after the coin is closed, a person who inserts coins or takes out coins can visually recognize from the outside of the machine whether or not coins remain in the trading plate 4 after the transaction. In this way, the coin depositing / dispensing machine itself can recognize the presence or absence of residual coins in the transaction dish 4, so that the reliability can be improved.

In the present embodiment, the trading tray 4 is integrally formed of a transparent material such as transparent resin, but the present invention is not limited to this, and the transparent material is provided only within the detection range of the residual coin detecting means 19. It may be formed by.

[0026]

As described above, according to the first aspect of the present invention, at least a part of the trading plate is made of a translucent material, and the residual effect detecting means is used to leave the trading plate in the trading plate. Since the presence / absence of coins is detected, it is possible to prevent erroneous detection of residual coins due to dust or dust adhering to the coins, and improve the reliability of the coin depositing / dispensing machine itself.

According to the second aspect of the invention, since the light receiving element of the residual coin detecting means is arranged in the light beam direction irradiated by the light emitting element of the residual coin detecting means, the detection area of the light receiving element is wide. Further, since the plurality of residual coin detecting means are arranged in parallel, the coins remaining on the transaction plate can be detected without leaking, and the reliability of the coin depositing / dispensing machine itself can be improved.

According to the third invention, the light emitting element of the residual coin detecting means for irradiating visible light is arranged above the trading plate,
Since the trading plate is illuminated by irradiating it on the trading plate, it is easy to confirm the coins on the trading plate, and it is possible to easily insert and remove coins from the outside of the machine.
