In this embodiment, 1-yen coins and 5-yen coins are stored in the first storage chamber 1Aa and the second storage chamber 1Ab of the coin storage unit 1A, respectively. 10-yen coins and 50-yen coins are stored in the first storage chamber 1Ba and the second storage chamber 1Bb of the coin storage unit 1B, respectively. 100-yen coins and 500-yen coins are stored in the first storage chamber 1Ca and the second storage chamber 1Cb of the coin storage unit 1C, respectively.

It should be noted that the combination of frequently used coins K and low coins K stored in one coin storage unit 1A, 1B and 1C is free. For example, it may be a combination of a 1-yen coin and a 50-yen or 500-yen coin, a combination of a 10-yen coin and a 5-yen or 500-yen coin, or a combination of a 100-yen coin and a 5-yen or 50-yen coin. Furthermore, different countries have different types and combinations of coins K.

Further, although not shown, the automatic change deposit / withdrawal machine 100 is provided with a bill storage / withdrawal device capable of storing and withdrawing a plurality of types of bills (for example, 1,000-yen, 5,000-yen, and 10,000-yen bills) by type. You may. The bill storage / withdrawal device has a bill introduction port, a bill identification unit for identifying the denomination of the bill introduced into the bill introduction port, and a transport passage for transporting the denomination-identified bill to the bill storage / withdrawal device. A bill transfer unit and a bill payout outlet for paying out bills in the bill storage / withdrawal device as change may be provided. In this case, the control unit 105 is electrically connected to each portion of the bill identification unit, the bill transport unit, and other bill storage / withdrawal devices.

The coin identification unit 102 identifies the denomination from a conventionally known method, for example, the size (including thickness), weight, material, etc. of the coin K, and transmits a coin identification signal to the control unit 105. Further, the banknote identification unit identifies the denomination from a conventionally known method, for example, a banknote printing pattern (including a watermark), a material of printing ink, vertical and horizontal dimensions, and the like, and transmits a banknote identification signal to the control unit 105.

The coin transport unit 103 switches between a coin moving mechanism (not shown) provided on the transport passage 103a and a plurality of transport passages 103a so that the coin K is transported to the first or second storage chamber described later of the coin storage unit 1A. It has a transport passage switching mechanism 103b. The same applies to the coin storage units 1B and 1C.

The coin moving mechanism includes a rubber endless belt provided on the transport passage 103a, and a plurality of pulleys for stretching and rotating the endless belt. By moving the coin K in the transport direction (direction of arrow A) while the endless belt is in contact with the flat surface of the coin K lying on the transport passage 103a, the coin K is slid on the transport passage 103a and transported one by one. Has been done.

Openings 3Aa, 3Ab, 3Ba, 3Bb, 3Ca, 3Cb are provided along the transport passage 103a for each type of coin K. Further, an opening 4 communicating with the spare coin storage portion 2 is provided.
The transport passage switching mechanism 103b corresponding to the opening 3Bb includes a solenoid 103b ₁ and a shutter 103b ₂ for opening and closing a communication hole provided in the transport passage 103a leading to the coin storage unit 1A by the solenoid 103b ₁ . A similar transport passage switching mechanism is provided for the other openings.

The control unit 105 receives the coin identification signal from the coin identification unit 102, and switches the transfer command signal for transporting the coin K to the first or second storage chamber of the predetermined coin storage unit according to the coin identification signal. It is configured to transmit to the mechanism 103b.
For example, when the control unit 105 receives the coin identification signal of a 1-yen coin from the coin identification unit 102, the control unit 105 transmits a transfer command signal for transporting the coin K to the first storage chamber 1Aa of the coin storage unit 1A of the transport passage switching mechanism 103b. Send to solenoid 103b ₁ . As a result, the solenoid 103b ₁ corresponding to the first storage chamber 1Aa of the coin storage unit 1A operates to open the shutter 103b ₂ in the direction indicated by the arrow F. Then, the 1-yen coin moving on the transport passage 103a falls into the first storage chamber 1Aa of the coin storage unit 1A and is stored. The control unit 105 also drops other coins K from the openings corresponding to the types of coins K and stores them in the coin storage unit 10 according to the type.
In this way, the coin transport unit 103 guides the coins K inserted from the coin insertion port 101 one by one to the openings corresponding to the types.

Further, the control unit 105 is configured to transmit a rotation command signal for commanding forward rotation and / or reverse rotation to a motor MA described later in a predetermined coin storage unit when change is required. At this time, the control unit 105 counts the number of coins K whose denomination has been identified by the coin identification unit 102, and calculates the total amount. In addition, the product price signal from the outside is received, and the total amount is compared with the amount included in the product price signal to determine whether or not change is necessary. Then, when change is required, a command signal for forward rotation and / or reverse rotation is transmitted to the motor MA of the coin storage unit according to the change. When the motor MA rotates in the forward direction, the coin K is paid out from the first storage chamber. At this time, the coin K is not paid out from the second storage room. When the motor MA rotates in the reverse direction, the coin K is paid out from the second storage chamber. At this time, the coin K is not paid out from the first storage chamber. Coins K are paid out from each room one by one at predetermined time intervals.

≪Coin storage units 1A, 1B and 1C≫
FIG. 2 is a perspective view showing a state in which a part of the wall portion constituting the coin storage units 1A, 1B and 1C of FIG. 1 is removed, and FIG. 3 is a perspective view showing the coin storage units 1A, 1B and 1C of FIG. It is a perspective view which shows the state which the other constituent wall part was removed.
Since the three coin storage units 1A, 1B and 1C provided in the automatic change deposit / withdrawal machine 100 have the same structure, respectively, in the following description, the coin storage unit 1A for storing 1-yen and 5-yen coins. Will be explained as a representative. The same applies to the other coin storage units 1B and 1C.

The coin storage unit 1A includes a coin storage unit 10 capable of individually storing two types of coins K, and a coin discharge mechanism 20 for selectively discharging the two types of coins K from the inside of the coin storage unit 10 to the outside.
The coin storage unit 1A has a first storage chamber 1Aa and a second storage chamber 1Ab for storing coins K according to the type, respectively, and the volume of the first storage chamber 1Aa is set to be larger than the volume of the second storage chamber 1Ab. Has been done.
The first storage chamber 1Aa has a wide first introduction port 11a for introducing one type of coin K (in this case, a 1-yen coin) into the first storage chamber 1Aa. Further, a first discharge port 11b (see FIG. 2) provided at the bottom for discharging the coin K in the first storage chamber 1Aa to the outside, and a slope portion 11c provided in a part of the first introduction port 11a. (See FIG. 3).

Further, at the bottom of the first storage chamber 1Aa, four circular holes and a side wall portion extending downward from the holes are formed, and a circular recess 11d into which a rotatable first rotating plate 21 is fitted, and a circular recess 11d. It has a concave curved surface portion 11e (see FIG. 2) provided around it. Then, a part of the stepped portion 11d ₁ (see FIG. 2) of the circular concave portion 11d adjacent to the concave curved surface portion 11e is cut out to form the above-mentioned first discharge port 11b. Two cylindrical first convex portions 24a and 24b are fixed to the circular recess 11d. The first convex portions 24a and 24b have a height equivalent to that of one coin. Each hole of the first rotating plate 21 is formed with a side wall portion extending downward, and the side wall portion is formed so that the side wall portion does not come into contact with the first convex portions 24a and 24b when the first rotating plate 21 rotates. A notch is formed in.

Coins K (1 yen coins) are randomly stored in the first storage chamber 1Aa instead of being stacked flat. At this time, the coin K falling from the coin transport portion 103 of the automatic change deposit / withdrawal machine 100 is received by the slope portion 11c and slid down onto the first rotating plate 21. Further, an L-shaped stirring rod 26 (see FIG. 3) is screwed to the rotating shaft of the first rotating plate 21. When the first rotating plate 21 rotates, the stirring rod 26 also rotates to stir the coin K in the first chamber 1Aa. Therefore, the standing coin K is laid down sideways, and the coin K is easily fitted into the hole of the first rotating plate 21.

When the motor MA rotates in the forward direction, the first rotating plate 21 rotates clockwise when viewed from above. The coin K fitted in any hole of the first rotating plate 21 moves on the circular recess 11d. When the front end side of the coin K comes into contact with the first convex portions 24a and 24b, the side wall portion of the first rotating plate 21 that pushes the coin K from the rear end side releases the coin K to the outer peripheral side of the first rotating plate 21. , The shape of the side wall portion is formed so that the coin K is discharged from the first discharge port 11b. When the motor MA rotates in the reverse direction, the first rotating plate 21 can rotate counterclockwise when viewed from above, but the transmission mechanism that transmits the drive of the motor MA to the first rotating plate 21 has a one-way clutch. doing. When the coin K fitted in any hole of the first rotating plate 21 moves counterclockwise together with the first rotating plate 21 and the tip side abuts on the first convex portions 24a and 24b, the coin K is acted on by a one-way clutch. The movement of the first rotating plate 21 is stopped, and the coin K stays at a position where it abuts on the first convex portions 24a and 24b.

The second storage chamber 1Ab has a second introduction port 12a for introducing another type of coin K (in this case, a 5-yen coin) into the second storage chamber 1Ab, and a coin K in the second storage chamber 1Ab. Has a second discharge port 12b (see FIG. 2) for discharging the coin to the outside. As a whole, it is formed in a cylindrical shape having an inner diameter slightly larger than the diameter of the coin K to be stored.
The second storage chamber 1Ab is arranged so that the second introduction port 12a is adjacent to the slope portion 11c of the first storage chamber 1Aa.
A coin K (5-yen coin) is introduced into the second storage chamber 1Ab by dropping into the storage chamber when the shutter 103b ₂ above the second storage chamber is released. The dropped coins K are piled up from the lower end side so that the faces of the coins K are in contact with each other and lined up. That is, coins K are stacked and stored in the second storage chamber. The stacked coin rows extend in the vertical direction. At the time of payout, a required number of coins K are ejected from the lower end side of the cylindrical member.

At the lower end of the second storage chamber 1Ab, the second rotating plate 22 is arranged in a direction parallel to the coins K stacked flat. The second rotating plate 22 has a second convex portion 25 at a position near the outer circumference of the upper surface thereof. The second convex portion 25 has a height equivalent to one coin K. When the second rotating plate 22 rotates, the second convex portion 25 crosses the lower end portion of the second storage chamber 1Ab. A notch is formed on the side wall of the lower end portion of the second storage chamber 1Ab so as to avoid the second convex portion 25 that crosses the lower end portion.

The coins stored in the second storage chamber 1Ab are stored in a state where the lower surface side of the lowermost coin K is in contact with the second rotating plate 22. When the motor MA rotates in the reverse direction, the second rotating plate 22 rotates accordingly. When the second convex portion 25 fixed to the second rotating plate 22 crosses the lower end of the second storage chamber 1Ab, the second convex portion 25 pushes the coin K at the lowermost end from the side. There is a gap of about one coin K between the second rotating plate 22 and the lower end of the second storage chamber 1Ab so that the pushed lowermost coin K is discharged from the second storage chamber 1Ab. The second discharge port 12b is formed as described above.

The driving force from the motor MA is the first connecting gear 210 (see FIG. 8), the connecting shaft 230 (see FIG. 8), and the second connecting gear 210 provided between the first rotating plate 21 and the second rotating plate 22. It is transmitted to the second rotating plate 22 via the connecting gear 220 (see FIG. 8). When the motor MA rotates in the opposite direction, the second rotating plate 22 and the second convex portion 25 rotate. Eventually, the lowermost coin K comes into contact with the side wall opposite to the second discharge port 12b of the second storage chamber 1Ab. At that time, the one-way clutch acts so as to stop together with the second convex portion 25 and the second rotating plate 22 that push the coin K.

As described above, when the motor MA rotates in the forward direction by the action of the two one-sided clutches, the coins K stored in the first storage chamber 1Aa are discharged one by one from the first discharge port 11b. When the motor MA rotates in the reverse direction, the coins K stored in the second storage chamber 1Ab are discharged one by one from the second discharge port 12b at the lower end.
The number of coins K to be ejected can be managed by the number of turns of the second rotating plate 22, that is, the angle at which the motor MA rotates in the reverse direction. Alternatively, a sensor may be provided near the second discharge port 12b to detect the coins K to be discharged and count the number of coins K.

For example, when the withdrawal amount of the coin K to be withdrawn is 296 yen, the control unit 105 receives one 1-yen coin from the first storage chamber 1Aa of the coin storage unit 1A and one 5-yen coin from the second storage chamber 1Ab. Withdraw one coin K for a total of 6 yen.
Further, the control unit 105 withdraws four 10-yen coins from the first storage chamber 1Ba of the coin storage unit 1B and one 50-yen coin from the second storage chamber 1Bb, for a total of 90 yen.
Further, the control unit 105 withdraws two 100-yen coins from the first storage chamber 1Ca of the coin storage unit 1C for a total of 200 yen, but withdraws 500-yen coins from the second storage chamber 1Bb. Is no longer needed.

In this way, the control unit 105 performs a process of withdrawing a required number of coins K from the coin storage units 1A, 1B and 1C according to the withdrawal amount, but in the following description, the coin storage unit 1A is represented. It is explained as. Here, the coin (1 yen coin) stored in the first storage chamber 1Aa will be referred to as a coin K ₁ , and the coin (5 yen coin) stored in the second storage chamber 1Ab will be referred to as a coin K ₂ . The same applies to the other coin storage units 1B and 1C.

Next, in step S102, the control unit 105 determines whether or not the coin K ₁ needs to be withdrawn from the first storage chamber 1Aa of the coin storage unit 1A (step S102).

When it is necessary to withdraw the coin K ₁ (when the determination in step S102 is Yes), the control unit 105 performs the withdrawal process of the coin K ₁ in step S103 (step S103). After that, the control unit 105 determines in step S104 (step S104).
The details of the withdrawal process of the coin K ₁ will be described later in the description of FIG.

On the other hand, when the withdrawal of the coin K ₁ is unnecessary (when the determination in step S102 is No), the control unit 105 determines in step S104 (step S104).

Next, in step S104, the control unit 105 determines whether or not it is necessary to withdraw the coin K ₂ from the second storage chamber 1Ba of the coin storage unit 1A (step S104).

When it is necessary to withdraw the coin K ₂ (when the determination in step S104 is Yes), the control unit 105 performs the withdrawal process of the coin K ₂ in step S105 (step S105). After that, the control unit 105 ends the withdrawal process of the coin storage unit 1A.
The details of the withdrawal process of coin K ₂ will be described later in the description of FIG. 7.

On the other hand, when the withdrawal of the coin K ₂ is unnecessary (when the determination in step S104 is No), the control unit 105 ends the withdrawal process of the coin storage unit 1A.

≪Procedure for coin discharge processing in the 1st storage room 1Aa≫
Next, a procedure for coin withdrawal processing in the first storage chamber 1Aa of the coin storage unit 1A will be described with reference to FIGS. 5 and 6.

In step S201 of FIG. 5, the control unit 105 rotates the motor MA in the forward rotation direction NR (step S201).
Here, in the coin storage unit 1A, the rotation directions of the first rotating plate 21, the second rotating plate 22, the motor MA, and each gear that rotate when the coin K ₁ in the first storage chamber 1Aa is paid out are set to "forward rotation direction NR". The rotation direction of the first rotating plate 21, the second rotating plate 22, and each gear that rotates when the coin K ₂ in the first storage chamber 1Ab is paid out will be described as "reverse rotation direction IR".
The same applies to the coin storage units 1B and 1C.

As shown in FIG. 6, the control unit 105 controls the rotation of the motors MA, MB, and MC by transmitting a rotation control signal to the motor drive IC 111.

The motor drive IC 111 is an IC that receives a rotation control signal from the control unit 105 and controls ON / OFF of the power supply and the polarity of the voltage supplied from the power supply circuit 113 to the motors MA, MB and MC.
The motor drive IC 111 controls the rotation direction (that is, forward rotation direction NR or reverse rotation direction IR) of each motor MA, MB and MC by the polarity of the voltage supplied from the power supply circuit 113 to each motor MA, MB and MC. can do.

Subsequently, in step S202 of FIG. 5, the control unit 105 determines whether or not the motor lock is detected (step S202).

When the motor lock occurs and the rotation of the motor MA is stopped, the current circuit flowing through the coil of the motor MA is always connected and short-circuited, so that a motor overcurrent occurs. Therefore, whether or not the motor lock has occurred can be detected by monitoring the current flowing through the motor drive IC 111.
As shown in FIG. 6, when the motor drive IC 111 detects a motor overcurrent, it notifies the control unit 105.

When the motor lock is detected (when the determination in step S202 is Yes), the control unit 105 executes the motor lock release process in steps S203 to S206 (steps S203 to S206).

On the other hand, when the motor lock is not detected (when the determination in step S202 is No), the control unit 105 resets the retry counter to 0 in step S207 (step S207).
Here, the retry counter is a counter that determines a standard for how many times the motor lock is retried in the motor lock release process of the coin K ₁ .

Subsequently, in step S208, the control unit 105 determines whether or not the withdrawal of a specified number of coins K ₁ has been completed (step S208).

When the withdrawal of the specified number of coins K ₁ is completed (when the determination in step S208 is Yes), the control unit 105 stops the rotation of the motor MA in step S209 (step S209). After that, the control unit 105 performs the process of step S210 (step S210).

On the other hand, when the withdrawal of the specified number of coins K ₁ has not been completed (when the determination in step S208 is No), the control unit 105 repeats the process of step S201 (step S201).

Next, in step S210, the control unit 105 causes the notification unit 109 (see FIG. 6) to notify the error information when the motor lock has not been released yet (step S210).
Here, the notification unit may notify the error information to a display unit such as a display, or may notify the error information by a voice generation unit such as a speaker.
After that, the control unit 105 ends the coin withdrawal process in the first storage chamber 1Aa.

Next, the motor lock release process will be described.
When the motor lock is detected in step S202, the control unit 105 stops the motor MA in step S203 (step S203).
Specifically, the control unit 105 transmits a control signal for stopping the motor MA to the motor drive IC 111, and the motor IC 111 applies a voltage of opposite polarity to the motor MA to rotate the motor MA in the forward rotation direction NR. Stop it.

Subsequently, in step S204, the control unit 105 determines whether or not the number of retries of the motor lock release process is less than a predetermined number of times (step S204).
When the number of retries of the motor lock release process is less than a predetermined number of times (when the determination in step S204 is Yes), the control unit 105 increases the retry counter by +1 in step S205 (step S205).
The specified number of times is set to, for example, three times, but it is set to an appropriate number of times in consideration of clearing the jam of coin K ₁ and convenience for the user.

Then, in the following step S206, the motor MA is rotated in the reverse rotation direction IR for a predetermined time (step S206). After that, the control unit 105 repeats the process of step S201 (step S201).

On the other hand, when the number of retries of the motor lock release process reaches a predetermined number of times (when the determination in step S204 is No), the control unit 105 stops the rotation of the motor MA in step S209 (step S209). ). After that, the control unit 105 performs the process of step S210 (step S210).

In this way, when the motor lock occurs, the coin K ₁ is clogged in the first storage chamber 1Aa by repeating the rotation of the forward rotation direction NR and the reverse rotation direction IR of the motor MA a predetermined number of times. It can be resolved.

≪Procedure for coin discharge processing in the second storage room 1Ab≫
Next, a procedure for coin withdrawal processing in the second storage chamber 1Ab of the coin storage unit 1A will be described with reference to FIG. 7.

In step S301 of FIG. 7, the control unit 105 rotates the motor MA in the reverse rotation direction IR (step S301).
Here, as shown in FIG. 6, the motor drive IC 111 receiving a command from the control unit 105 reverses the polarity of the voltage applied to the motor MA to rotate the motor MA from the forward rotation direction NR to the reverse rotation direction. It can be transferred to IR.

Subsequently, in step S302, the control unit 105 determines whether or not the withdrawal of a specified number of coins K ₂ has been completed (step S302).

When the withdrawal of the specified number of coins K ₂ is completed (when the determination in step S302 is Yes), the control unit 105 stops the rotation of the motor MA in step S303 (step S303). After that, the control unit 105 ends the coin withdrawal process in the second storage chamber 1Ab.

On the other hand, when the withdrawal of the specified number of coins K ₂ has not been completed (when the determination in step S302 is No), the control unit 105 repeats the process of step S301 (step S301).

As described in the explanations of FIGS. 2 and 3, in the second storage chamber 1Ab where the coins K ₂ are stacked and stored flat, the motor lock due to the clogging of the coins K ₂ is unlikely to occur, so the motor lock release process is adopted. Not.
In contrast, the first storage room 1Aa, since the coin K ₁ at different angles are stored in a random, clogging of the coin K ₁ is likely to occur. Therefore, in the first storage chamber 1Aa, a motor lock release process is provided to clear the clogging of the coin K ₁ by rotating the IR in the reverse rotation direction.

However, when the motor MA is rotated in the reverse rotation direction IR in order to clear the clogging of the coin K ₁ when the motor lock occurs in the first storage chamber 1Aa, the coin K ₂ is paid out from the second storage chamber 1Ab. , Unintended payout of coin K ₂ may occur.

Therefore, in order to solve such a problem, the coin storage units 1A, 1B and 1C of the first embodiment of the present invention are provided with a coin feeding mechanism as shown in FIGS. 8 and 9.
In the following description, the coin storage unit 1A will be described as a representative, but the same applies to the other coin storage units 1B and 1C.

≪Coin feeding mechanism of coin storage unit 1A≫
Hereinafter, the coin feeding mechanism of the coin storage unit 1A will be described with reference to FIGS. 8 to 10.
FIG. 8A is an explanatory diagram showing the operation of the motor MA during rotation of the forward rotation direction NR in the coin feeding mechanism of each coin storage unit 1A of the first embodiment, and FIG. 8B is an explanatory view of the embodiment. It is explanatory drawing which shows the operation at the time of rotation of the reverse rotation direction IR of a motor MA in the coin feeding mechanism of each coin storage unit 1A of 1, FIG. 9A is the 1st connection gear shown in FIG. 8A. It is an explanatory view which looked at 210 from the upper side, FIG. 9 (B) is the explanatory view which looked at the 1st connecting gear 210 shown in FIG. 8 (B) from the upper side, and FIG. 10 (A) is FIG. 8 (A). FIG. 10B is an explanatory view of the first connecting gear 210 as viewed from above, and FIG. 10B shows a state when the rotation of the first connecting gear 210 in the reverse rotation direction IR is started from the state of FIG. 10A. FIG. 10 (C) is an explanatory diagram showing a state when the first connecting gear 210 is rotated in the reverse rotation direction IR by about 180 ° from the state of FIG. 10 (B). FIG. 10D is an explanatory diagram showing a state when the first connecting gear 210 is rotated in the reverse rotation direction IR by about 360 ° from the state of FIG. 10B.
For convenience of explanation, FIGS. 8 to 10 omit the illustration of the shaft and the support member that support each gear and the rotating plate.

<< Operation of coin feeding mechanism when the motor MA rotates in the forward rotation direction NR >>
First, the operation of the coin feeding mechanism when the motor MA rotates in the forward rotation direction NR will be described.
In FIG. 8A, the rotational driving force from the motor MA is transmitted to the first rotating plate 21 of the first accommodating portion 1Aa via the motor gear 200, and the rotation of the first rotating plate 21 causes the first accommodating chamber 1Aa. The coin K ₁ inside is discharged to the outside.

Further, the first connecting gear 210 rotates in conjunction with the rotation of the first rotating plate 21.
As shown in FIG. 8A, in the first connecting gear 210, the engaging convex portion 210a is fixed to the peripheral edge of the upper surface, and the upper end of the connecting shaft 230 is inserted into the through hole at the center of the first connecting gear 210. However, the first connecting gear 210 is not fixed to the connecting shaft 230, but is connected so as to be rotatable with respect to the connecting shaft 230.

Further, at the upper end of the connecting shaft 230, an engaging piece 230a is provided at a position where it rotates together with the connecting shaft 230 and can engage with the engaging convex portion 210a provided on the upper surface of the first connecting gear 210.
As shown in FIG. 9A, when the engaging convex portion 210a on the upper surface of the first connecting gear 210 engages with the engaging piece 230a, the rotational force of the first connecting gear 210 with respect to the engaging convex portion 210a. It is transmitted to the connecting shaft 230 via engagement. At this time, the connecting shaft 230 rotates together with the first connecting gear 210 in the forward rotation direction NR.

On the other hand, the lower end of the connecting shaft 230 is inserted into a through hole at the center of the second connecting gear 220, and a one-way clutch 241 is provided between the connecting shaft 230 and the second connecting gear 220. ..

As shown in FIGS. 8A and 8B, the one-way clutch 241 transmits the rotational force of the reverse rotation direction IR of the connecting shaft 230 to the second connecting gear 220, but the forward rotation direction NR of the connecting shaft 230. It is configured so that the rotational force is not transmitted.

As described above, since the rotational force of the connecting shaft 230 in the forward rotation direction NR is not transmitted to the second connecting gear 220 by the one-way clutch 241, the second connecting gear 220 does not rotate in the forward rotation direction NR, and the first The second rotating plate 22 linked to the two connecting gears 220 also does not rotate in the forward rotation direction NR.

As described above, when the motor MA rotates in the forward rotation direction NR, the first rotating plate 21 rotates, but the second rotating plate 22 does not rotate, so that only the coin K ₁ can be paid out.

≪Operation of coin feeding mechanism when the motor MA rotates in the reverse rotation direction IR≫
Next, the operation of the coin feeding mechanism when the motor MA rotates in the reverse rotation direction IR will be described.
As shown in FIG. 8 (B), when the motor MA is rotated in the reverse rotation direction IR, the motor gear 200 rotates in the direction opposite to that in FIG. 8 (A), and the rotational driving force of the motor gear 200 is the first rotation. It is transmitted to the plate 21.

Further, the first connecting gear 210 rotates in conjunction with the rotation of the first rotating plate 21.
As shown in FIG. 9B, when the engaging convex portion 210a on the upper surface of the first connecting gear 210 engages with the engaging piece 230a, the rotational force of the first connecting gear 210 with respect to the engaging convex portion 210a. It is transmitted to the connecting shaft 230 via engagement.
Therefore, the connecting shaft 230 rotates in the reverse rotation direction IR together with the first connecting gear 210.

Further, since the rotational force of the reverse rotation direction IR of the connecting shaft 230 is transmitted to the second connecting gear 220 by the one-way clutch 241, the second connecting gear 220 is also the first connecting gear as shown in FIG. 8 (B). It rotates in the reverse rotation direction IR together with 210.
As a result, the second rotating plate 22 linked to the second connecting gear 220 also rotates in the reverse rotation direction IR, so that the coin K ₂ can be manipulated.

By the way, the conventional coin feeding mechanism has a mechanism in which the rotational driving force of the motor MA is directly transmitted to the first rotating plate 21 and the second rotating plate 22 via the gear. Therefore, when the motor lock occurs in the first storage chamber 1Aa, when the motor MA is rotated in the reverse rotation direction IR in order to clear the clogging of the coin K ₁ , the second rotation is received by the rotational driving force of the motor MA. Since the plate 22 also rotates in the reverse rotation direction IR, the coin K ₂ may be paid out from the second storage chamber 1Ab, which may cause an unintended payout of the coin K ₂ .

In order to solve such a problem, in the coin feeding mechanism of the first embodiment of the present invention, even if the first rotating plate 21 rotates in the reverse rotation direction IR, the rotational force immediately applies to the second rotating plate 22. The second rotating plate 22 is configured to start rotating after the first rotating plate 21 has rotated a certain number of times without being transmitted.

<< Mechanism for delaying delivery of coin K ₂ from the second storage chamber 1Ab when the motor MA rotates in the reverse rotation direction IR >>
Hereinafter, a mechanism for delaying the delivery of the coin K ₂ from the second storage chamber 1Ab at the time of rotation of the motor MA in the reverse rotation direction IR according to the first embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 10 (A), after rotating the first connecting gear 210 in the forward rotation direction NR, the first connecting gear 210 is inverted in the reverse rotation direction IR as shown in FIG. 10 (B). To do.

In FIG. 10A, the rotational force of the first connecting gear 210 in the forward rotation direction NR is transmitted to the connecting shaft 230 through the engagement between the engaging convex portion 210a and the engaging piece 230a.
On the other hand, in FIG. 10B, when the rotation of the IR in the reverse rotation direction of the first connecting gear 210 is started, the engagement between the engaging convex portion 210a and the engaging piece 230a is released, so that the first connecting gear 210 The rotational force of the reverse rotation direction IR is not transmitted to the connecting shaft 230.

Further, as shown in FIG. 10C, even when the first connecting gear is rotated in the reverse rotation direction IR by about 180 °, the engaging convex portion 210a is located at a position away from the engaging piece 230a. The rotational force of the reverse rotation direction IR of the first connecting gear 210 is not transmitted to the connecting shaft 230.

However, as shown in FIG. 10D, when the first connecting gear 210 makes almost one rotation and the engaging convex portion 210a engages with the engaging piece 230a again, the first connecting gear is engaged through the engagement. The rotational force of the reverse rotation direction IR of 210 is transmitted to the connecting shaft 230.

In this way, when the first connecting gear 210 changes from the rotation of the forward rotation direction NR to the rotation of the reverse rotation direction IR, the rotational force of the reverse rotation direction IR of the first connection gear 210 is immediately applied to the second rotation plate 22. A certain delay time DT occurs without being transmitted to.
Therefore, when the motor lock occurs, even if the motor MA is rotated in the reverse rotation direction IR in order to clear the clogging of the coin K ₁ , until the delay time DT elapses (or the delay time DT is reached). (Until the motor MA rotates by the corresponding specified rotation speed), the coin K ₂ is not delivered from the second storage chamber 1Ab.

<< An example of motor unlocking operation of motor MA >>
Next, an example of the motor lock release operation of the motor MA will be described with reference to FIG.
FIG. 11 is a flowchart showing an example of the motor unlocking operation of the motor MA of the coin storage unit 1A.

In step S401 of FIG. 11, when the motor lock is detected during dispensing process of the coin K ₁ (step S401), the time control unit 105, in subsequent step S402, after stopping the motor MA, predetermined, It rotates in the reverse rotation direction IR (step S402).

Here, the rotation of the first connecting gear 210 is reversed from the forward rotation direction NR to the reverse rotation direction IR, and after the engaging convex portion 210a is disengaged from the engaging piece 230a, the engaging piece 230a is again used. When the delay time required to engage with the motor MA is DT, it is desirable that the rotation time of the reverse rotation direction IR of the motor MA is equal to or less than the delay time DT.

In the first embodiment, when the delay time DT is 1000 ms, the rotation time of the reverse rotation direction IR of the motor MA is set to 900 ms, which is shorter than the delay time DT, so that the coin K ₂ is paid out from the second storage chamber 1Ab. It is possible to release the motor lock.

Next, in step S403, the control unit 105 stops the motor MA and then rotates it again in the forward rotation direction NR (step S403).
At this time, by setting the rotation time of the forward rotation direction NR of the motor MA to 800 ms, which is shorter than the rotation time of 900 ms of the reverse rotation direction IR of step S402, the position where the engaging convex portion 210a engages with the engaging piece 230a again. The motor lock can be released without rotating the first connecting gear 210.

Subsequently, when the motor lock is detected again in step S404 (step S404), the control unit 105 assumes that the clogging of the coin K ₁ has not been cleared yet, and after stopping the motor MA in the following step S405, after stopping the motor MA, It is rotated again in the reverse rotation direction IR for 800 ms (step S405).

Next, when it is detected in step S406 that the motor lock has been released (step S406), the control unit 105 restarts the withdrawal process of the coin K ₁ in the following step S407 (step S407).

In this way, one motor MA is repeatedly rotated in the forward rotation direction NR or the reverse rotation direction IR within a range in which the rotational force of the reverse rotation direction IR of the first connecting gear 210 is not transmitted to the second rotation plate 22. As a result, it is possible to realize an automatic change deposit / withdrawal machine 100 that releases the locked state of the motor without causing an unintended payout of the coin K ₂ .

(Embodiment 2)
When the motor MA rotates in the reverse rotation direction IR, the rotation position of the engaging convex portion 210a is monitored by an optical sensor or the like, the first connecting gear 210 makes approximately one rotation, and the engaging convex portion 210a reappears to the engaging piece 230a. The rotation of the motor MA in the reverse rotation direction IR may be stopped at a position immediately before engaging with the motor MA.

In this way, the rotation of the motor MA is stopped at an appropriate position without presetting the rotation speed or the rotation time of the motor MA until the engaging convex portion 210a engages with the engaging piece 230a again. be able to.

(Embodiment 3)
By adjusting the ratio of rotation between the first rotating plate 21 and the second rotating plate 22 or the time (or angle) until the coins K ₁ and K ₂ are ejected, the rotation of the motor MA is NR in the forward rotation direction. After reversing in the reverse rotation direction IR, a delay time DT may occur until the coin K ₂ is paid out.

For example, the first rotating plate 21 and the first rotating plate 21 and the first rotating plate 21 and the clogging of the coin K ₁ are cleared so that the first rotating plate 21 rotates greatly before the second rotating plate 22 rotates to the position where the coin K ₂ is discharged. Adjust the ratio of rotation between the second rotating plates 22 or the time (or angle) until the coins K ₁ and K ₂ are ejected.

By doing so, the unintended coin K ₂ can be paid out by adjusting the ratio of rotation between the first rotating plate 21 and the second rotating plate 22 or the time (or angle) until the coin is ejected. It is possible to realize an automatic change deposit / withdrawal machine 100 that releases the motor lock without causing it to occur.

(Embodiment 4)
When the rotation of the motor MA is changed from the forward rotation direction NR to the reverse rotation direction IR when the motor lock occurs, the first convex portions 24a and 24b and so that the delay time DT until the coin K ₂ is paid out becomes long. The position of the second convex portion 25 may be adjusted.

In this way, by adjusting the positions of the first convex portions 24a and 24b and the second convex portion 25, the automatic change deposit / withdrawal machine releases the motor lock without causing an unintended payout of coin K _2. 100 can be realized.

(Embodiment 5)
The second convex portion 25 is provided so as to be housed in the second rotating plate 22, and when the rotation of the motor MA is changed from the forward rotation direction NR to the reverse rotation direction IR when the motor lock occurs, the upper surface of the second rotation plate 22 The second convex portion 25 of the above may be stored in the second rotating plate 22 for a predetermined time.

In this way, the coin K ₂ is not fed out from the second storage chamber 1Ab by the second convex portion 25 for a predetermined time when the motor MA rotates in the reverse rotation direction IR, so that a connecting gear or the like is not provided. It is possible to realize an automatic change deposit / withdrawal machine 100 that releases the motor lock without causing an unintended payout of coin K ₂ with a simple mechanism.
