BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1 of the Invention A medal delivery device according to an embodiment of the invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing an outline of a medal sending apparatus according to the first embodiment of the invention. 1A is a sectional view and FIG. 1B is a perspective view. In FIGS. 1A and 1B, the display of the drive mechanism is omitted. In FIG. 1B, the display of the medal receiving portion 1 and the like is omitted.

In FIGS. 1 (a) and 1 (b), reference numeral 1 denotes a shape in which an opening A through which inserted medals pass is provided at the bottom and guides the inserted medals to the opening A, for example, a funnel shape. The medal receiving portion 2 that it has is provided on the lower side of the medal receiving portion 1, and the belt 3 that receives the medal from the opening A and conveys it is provided between the medal receiving portion 1 and the belt 2. , A roller for separating a plurality of medals inserted in an overlapping state. The roller 3 is provided substantially parallel to the belt 2. A gap b is provided between the roller 3 and the belt 2. When the medals are conveyed one by one, the gap b is slightly wider than the thickness of one medal and is narrower than the thickness of two medals. In this case, the belt 2 conveys the medals one by one.
The size of the gap b is determined according to the thickness of the medals to be conveyed and the number of conveyed medals. As indicated by the arrow in the figure, the roller 3 moves in the direction opposite to the conveying direction of the belt 2 in the gap b. More specifically, the roller 3 rotates so that the side of the roller 3 that faces the conveyance direction of the belt 2 moves in the direction opposite to the conveyance direction of the surface of the belt 2 that faces the roller 3. The fact that the roller 3 moves in the direction opposite to the conveying direction of the belt 2 means this.

A medal guide 4 is provided at the end of the belt 2 and guides the conveyed medals in a predetermined direction. A roller 6 drives the belt 2. Reference numeral 7 is a medal guide for guiding the medal at the opening A onto the belt 2.

Reference numeral 5 is an insertion slot medal sensor for detecting the presence or absence of a medal in the vicinity of the opening A of the medal receiving portion 1. The medal sensor 5 is a metal sensor that reacts with the metal forming the medal. For example, it is a sensor that contacts a medal and applies electricity to the medal, and determines the presence or absence of the medal and / or the type of the medal based on the magnitude of the electric resistance. For example, it is a sensor that determines the presence or absence of medals in a non-contact manner by using eddy current. In this case, only medals can be detected, and even if small articles such as cigarettes and lighters that are not related to medals are placed in the slot, they can be distinguished from medals. The medal sensor 5 may be an optical sensor. For example,
It is a sensor that determines the presence or absence of a medal by detecting the light reflected on the surface of the medal (or shielded by the medal). In this case, there is no malfunction due to the difference in the material of the medal.

FIG. 2 shows the medal delivery device 100 of FIG.
An example in which is applied to a gaming machine (slot machine) is shown. The medals thrown by the medal sending device 100 can be sent to the medal selector, the medal internal storage device, and the hopper.

As shown in FIG. 2, the slot machine 10 has a rectangular box-shaped housing 11. A square window-shaped display window 12 facing the player side is formed in the central portion and the upper portion of the housing 11. Then, in the center of the display window 12 in the central portion, a symbol display window 13 through which the symbols 61 of the three rotating reels 40 can be seen is formed. The pet switch 16 is a switch located below the rotating reel 40, and reduces the number of stored medals and substitutes for inserting medals. The settlement switch 17 is a switch located diagonally below the rotating reel and pays out the stored inserted medals. The start switch 30 is a lever positioned diagonally below the rotary reel 40, and starts driving the reel unit 60 on condition that the game medal is inserted or the pet switch 16 is inserted. The stop switch 50 is for stopping the drive of the reel unit 60. The reel unit 60 is composed of three rotating reels 40. Each of the rotary reels 40 includes a rotary drum made of synthetic resin, and a tape-shaped reel tape 42 attached around the rotary drum.
On the outer peripheral surface of the reel tape 42, a plurality (for example, 2
The (one) pattern 61 is displayed.

FIG. 3 shows a state in which the vicinity of the medal insertion slot of the medal delivery device 100 is viewed obliquely from above. 101 is a start / stop switch. By operating this switch 101, the medal sending device 100 operates /
Stop. When a player inserts a large number of medals into the medal receiving portion 1, the medals slide on the slope of the funnel-shaped medal receiving portion 1 to reach the opening A, and then drop onto the belt 2. The size of the opening A is slightly large so that a plurality of medals can be easily dropped. Therefore, 1, 2
Not only when about a few medals are thrown in, but also when a large number of medals are thrown at the same time, some of them are surely dropped onto the belt 2 and conveyed. As will be described later, even if a plurality of medals fall onto the belt 2 through the opening A, the medals are conveyed one by one (in order to inspect and sort the medals in the medal selector and to count the medals, Is desirable to be transported one by one). The medal receiving portion 1 may be removable. A medal batch insertion mechanism is provided inside the medal delivery device 100.

FIG. 4 is a view of the medal sending device 100 as seen from diagonally above. As shown by the dotted line, the medal receiving portion 1
Two sensors 5a and 5b are provided on the back surface of the. These sensors 5a and 5b detect medals placed near the opening A of the medal receiving portion 1.

FIG. 5 shows a state in which the medal receiving portion 1 is removed. Two sensors 5a and 5b are provided on the back side of the medal receiving portion 1. It can be seen that the medal guide 7 is provided below the opening A.

FIG. 6 shows the case where one medal M is inserted. In FIG. 6, the medal M passing through the opening A of the medal receiving portion 1 falls on the belt 2. Since the belt 2 moves in the direction of the arrow, the tip of the medal M also moves in the same direction. Then, the other end of the medal M also falls on the belt 2. Since the gap between the belt 2 and the roller 3 is wider than the thickness of one medal, the medal M is conveyed by the belt 2 and reaches the end of the belt 2. Then, the medal M falls from the end portion of the belt 2 along the medal guide 4. Then, it is guided to a medal selector (not shown).

When a plurality of (two) medals M and M'are inserted, the lower medal M is similarly conveyed, but the medal M'does not come into contact with the belt 2. Instead, the upper medal M '
Comes into contact with the roller 3 and is slightly lifted up and pushed back toward the opening A side. The medal M ′ is in the opening A while the medal M is being conveyed. In this way, the medal M ′ is separated from the medal M. When the medal M is conveyed, the medal M ′ falls a little and becomes the same state as the medal M of FIG. Then, the medal M ′ is also similarly conveyed.

Consider the case without the roller 3.
If two medals are thrown in the overlapping state, they will be conveyed by the belt 2 as they are. This may cause the medal selector to be clogged with medals. Consider a case where a plate is used instead of the roller 3 to provide a gap for one medal. When two medals are thrown in a state of overlapping, the two medals are conveyed together by a belt. Then, there is a risk that the medals will be blocked in the gaps. Therefore, in order to convey the medals one by one without causing a jam of the medals when a plurality of medals are thrown in at the same time, it is desirable to provide the roller 3, for example.

FIG. 7 is a block diagram of a medal sending device according to the embodiment of the present invention. Based on the signal from the medal sensor 5 at the insertion slot and / or the signal from the switch 101, the control unit 102 causes the drive unit 103 of the collective insertion mechanism to operate.
(For example, a motor (not shown) that rotates the rollers 3 and 6) is driven. Further, this apparatus has a load detection unit 104 that detects a load applied to the collective loading mechanism drive unit 103.
And a separation means pressure detection unit for detecting the pressure applied to the separation means 3, and a carry-out exit medal sensor 1 provided at the carry-out exit for detecting that medals have been sent out from the batch insertion device.
06 and. The load detection unit 104 is, for example, the drive unit 1.
The load condition is detected based on the motor current value of 03.
Alternatively, the torque of the motor may be directly detected. The separating means pressure detection unit 105 is a sensor that detects, for example, the force applied to the support portion of the roller 3, and detects the impact when the medal hits the roller 3 and the pushing force by the medal conveyed on the belt. Unloading medal sensor 106
Is, for example, a sensor (similar to the insertion port sensor 5) provided between the medal guide 4 and the roller 6 (see FIG. 13 and its description below).

Next, the operation of the medal sending device according to the embodiment of the present invention will be described. First, the driving procedure of the batch loading device based on the signal from the sensor will be described with reference to FIG. S1: Receive a signal from the sensor 5. S2: Based on the received signal, it is determined whether or not a medal has been inserted into the insertion slot A portion. S3: When a medal is thrown, the batch throwing device is driven. The medals thus inserted are conveyed to the medal hopper through the medal selector.

However, if the credit limit is exceeded, it is not preferable to increase the credit any more,
If the credit limit is exceeded, the batch loading device is stopped. The credit signal is sent from a control unit (microcomputer) (not shown) in the slot machine.
Similarly, when the internal hopper is full, driving of the batch feeding device is stopped. The hopper full signal is sent from a sensor in the hopper (not shown). The processing of S4 to S10 relating to these will be described. S4: It is determined whether or not errors E1 to E5 have occurred. When an error occurs, the driving of the batch feeding device is stopped (S11). Details of the errors E1 to E5 are shown in FIG. When any of the errors E1 to E5 occurs, an error is displayed on the game medal payout number display device, and the game becomes impossible. This state continues until a predetermined release procedure is executed, and when the release procedure is executed, the state before the abnormality occurs is restored. S5: It is determined whether or not the motor is started and the insertion of a medal is not detected within a certain period of time. In the case of YES, an abnormality such as a medal jam may be considered, so the driving of the batch insertion device is stopped (S11). S6: It is determined whether the number of credits has reached the limit (50). If YES, the drive of the batch insertion device is stopped to prohibit further credits (S
11). S7: Determine whether the bet number has reached the upper limit.
Bet means placing a medal on a slot machine. 1 play 1 bet is the basic, but depending on the machine, there may be restrictions such as 2 bet.
If YES, the driving of the batch loading device is stopped in order to prohibit further bets (S11). S8: Determine whether the game is in progress. In-game is a period during which the start river is turned on, the reel is rotated, and then the reel is stopped. If it is during the game, the driving of the batch insertion device is stopped (S11). S9: Determine whether or not replay is in progress. Since it is not necessary to insert medals during replay, driving of the batch insertion device is stopped (S11). S10: Based on the signal from the sensor 5, it is determined whether or not there is no medal in the insertion slot, and when the medal is gone, the driving of the batch insertion device is stopped (S11).

According to the above procedure, when a medal is inserted into the insertion slot, the batch insertion device can be driven to automatically convey the medal to the medal hopper.

Next, the driving procedure of the batch feeding device will be described with reference to FIGS. FIG. 10 is a processing flowchart for rotating the belt in the reverse direction when a medal is inserted, and FIG. 11 is a processing flowchart for increasing the belt speed when a large number (large number) of medals are thrown at once.

Here, in the present invention, "a large amount (a large amount)"
"When medals are thrown in" means "when the amount of medals that are usually, or significantly exceeding, the amount of medals that are normally thrown at one time is thrown in" When an amount of medals that exceeds the range is thrown while the amount of medals is being thrown in ". Specifically, for example, the upper limit amount (predetermined amount) is determined from the amount of medals that are normally thrown at once, and when this upper limit amount (predetermined amount) is exceeded, that is, "the number of medals that have been exceeded is exceeded. Or when the upper limit amount (predetermined amount) is simply determined and the upper limit amount (predetermined amount) is exceeded, that is, when the medals are inserted in excess of the predetermined amount. S20: It is determined whether there is a medal in the insertion slot but the medal is not ejected.

Here, it is determined to be YES when all of the following conditions are satisfied. If YES is determined, the process S is performed.
Do 23. A medal is detected at the slot by the slot medal sensor 5. The drive unit 103 is driven by the control unit 102. The carry-out medal sensor 106 does not detect the carry-out of medals.

If the carry-out medal sensor 106 is not provided, YES is determined under the following conditions. The drive unit 103 is driven by the control unit 102. A medal is detected at the insertion slot by the insertion slot medal sensor 5, but this is constant (not intermittent).
Or it remains detected for a long time. S21: It is determined whether the load of the drive unit 103 is equal to or greater than a predetermined value (first threshold) (overload).

When the load of the drive unit 103 detected by the load detection unit 104 is equal to or more than the first threshold value, it is determined as YES. For example, the current value of the motor of the drive unit 103 is measured, and when the current value is equal to or larger than a predetermined value, it is determined as an overload. Yes
If so, the process S23 is executed. S22: It is determined whether the pressure applied to the separating means 3 does not change.

In a normal state, the separating means (roller)
3 is under intermittent pressure. For example, medals thrown into the separating means may collide with each other, collide with the belt during conveyance, or be lifted up by overlapping medals. This pressure is detected by the separation means pressure detection unit 105. If this pressure is constant without interruption, it is considered that the medal has stopped moving, that is, the medal has been sandwiched between the belt 2 and the roller 3. In such a state, YES is determined and the process S23 is executed. S23: When it is determined in S20 to S22 that the medals are jammed, the control unit 102 drives the drive unit 103 in the reverse direction for a predetermined time. As a result, the sandwiched medals can be returned to the normal state.

When the upper limit is set for the number of times of the processing of S23 and the same state is obtained even after repeating a predetermined number of times or more,
The driving of the batch feeding device may be stopped.

Next, the flowchart of FIG. 11 will be described. S30: It is determined whether a large number of medals have been inserted into the insertion slot.

When the output of the slot medal sensor 106 outputs an analog value according to the amount of the object, the amount of inserted medals can be determined based on the output level. When the level is equal to or higher than the predetermined value, YES is determined, and the process S32 is executed to accelerate the rotation of the belt. S31: It is determined whether the load on the drive unit 103 is equal to or greater than a predetermined value (second threshold value).

When a large number of medals are thrown in and the tension applied to the belt exceeds a certain level (heavy), the load on the drive unit 103 increases. In this case, YES is determined. This state is a case that does not correspond to the above S21, and means that a load of a predetermined amount or more is applied. That is, it is when a large number of medals are thrown in at one time, although they are within the processable range. In such a case, it is preferable to move the belt quickly to convey the medal quickly. For example, the first threshold> the second threshold. S32: When it is determined in S30 and S31 that a large number of medals have been inserted, the control unit 102 increases the belt speed for a predetermined time. As a result, the medals can be quickly carried out, the spilled coins can be eliminated, and clogging of medals can be prevented.

When the upper limit is set for the number of times of the processing of S32 and the same state is obtained even after repeating a predetermined number of times or more,
The driving of the batch feeding device may be stopped.

According to the embodiment of the present invention, the belt can be rotated in the reverse direction when the medal is jammed or when the medal is sandwiched between the roller 3 and the belt 2. As a result, the clogging of medals and the like can be eliminated and the normal state can be restored. Also, the belt can be moved quickly when a large number of medals are thrown in. This makes it possible to process a large number of medals. Embodiment 2 of the invention. A specific example in which an optical sensor (transmission type photo sensor) is used as the slot medal sensor 5 or the carry-out medal sensor 106 will be described.

FIG. 12 uses a transmissive photosensor. U-shaped photo sensors are provided above and below the opening A. The medal moves through the opening A in the direction perpendicular to the drawing sheet. The photo sensor 5 includes a portion 5-U including a light emitting element and a portion 5-L including a light receiving element. A slit S for passing light of a light emitting element (not shown) is provided on the portion 5-U side of the opening A. Similarly, a slit S for guiding light to the light receiving element 5-S is provided on the portion 5-L side of the opening A. Slit S
Is formed, for example, by providing a hole in a resin member forming the medal receiving portion 1. The light of the light emitting element of the portion 5-U enters the light receiving element 5-S through the slit S.
The optical axis L of the transmissive photosensor of FIG. 12 is oblique. In accordance with this, the slit on the 5-U side has a 5-
The slits on the L side are arranged slightly displaced. With such a structure, dust or the like that has passed through the upper slit S does not adhere to the sensor 5-S. This makes it possible to prevent malfunction.

FIG. 13 and FIG. 14 are explanatory views of an attached state of the optical sensor according to the third embodiment of the invention. Figure 1
3 shows a cross section of the medal receiving portion 1, and FIG. 14 shows a view of the medal receiving portion 1 seen from above. FIG. 14 also shows a state in which an optical sensor is attached as the carry-out outlet medal sensor 106.

There is no medal in the opening A when no medal is inserted. The light from the light emitting element is incident on the light receiving element 5-S as shown in FIG.
S outputs a light reception signal. On the other hand, since the medal enters the opening A when the medal is inserted, the optical axis L is blocked. The light receiving element 5-S does not output a light receiving signal. By detecting this with a microcomputer not shown,
The presence or absence of medals can be determined. Embodiment 3 of the invention. A specific example in which an optical sensor (reflection-type photo sensor) is used as the slot medal sensor 5 or the carry-out medal sensor 106 will be described. The present embodiment can be applied to both the belt type mechanism and the slide type mechanism.

FIG. 15 uses a reflection type photo sensor. The photo sensor 5 is provided above (or may be below) the opening A. The medal moves through the opening A in the direction perpendicular to the drawing sheet. The photo sensor 5 includes a light emitting element and a light receiving element. Slits for passing light of a light emitting element (not shown) are provided above and below the opening A. The slit S is formed, for example, by providing a hole in a resin member forming the medal receiving portion 1.
L is the optical axis. The light of the light emitting element passes through the slit S, the opening A, and exits to the opposite side of the sensor 5.

16 and 17 are explanatory views of an attached state of the optical sensor according to the fourth embodiment of the invention. Figure 1
6 shows a cross section of the medal receiving portion 1, and FIG. 17 shows a view of the medal receiving portion 1 seen from above.

There is no medal in the opening A when no medal is inserted. The light from the light emitting element passes through the opening A as shown in FIG. 16 and does not return to the light receiving element (not shown) provided in the sensor 5. The light receiving element does not output a light receiving signal. On the other hand, when a medal is inserted, the medal enters the opening A and the medal exists on the optical axis L. Then, the light of the light emitting element is reflected on the medal and a part of the light is incident on the light receiving element. As a result, the light receiving element outputs a light receiving signal. The presence or absence of medals can be determined by detecting this with a microcomputer (not shown).

As shown in FIG. 12, the lower slit may be slightly displaced from the upper slit. Further, when the inner surface of the opening A does not reflect light (for example, is colored black), the lower slit in FIG. 15 may not be provided.

As an application of the present invention, an example in which the present invention is applied to a gaming machine (slot machine) has been given in the embodiment, but the present invention is not limited to this. For example, the present invention can be applied to the insertion and / or return of coins of an automatic vending machine, the automatic teller machine of a financial institution, and the like.
