DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medal selector used for a gaming machine such as a slot machine, and more particularly to a medal selector for reliably selecting medals having an outer diameter smaller than a predetermined size.
It can be excluded from the medal passage.

[0002]

2. Description of the Related Art Conventionally, this type of medal selector has a medal passage inclined downward, in which medals inserted from a medal insertion slot roll. The above-mentioned conventional medal passage is provided with a lower side plate and an upper side plate that are opposed to each other with a medal passing distance therebetween in the thickness direction of the medal and that are inclined in the thickness direction of the medal with the medal passage interposed therebetween. Was.

[0003] In the above-mentioned conventional lower side plate, small-diameter medals having an outer diameter smaller than the predetermined outer diameter and having a height less than the predetermined outer diameter are smaller than the medals having a height from the bottom of the medal passage. A drop hole was formed to fall out of the passage.
Then, the medal inserted from the medal insertion slot rolls toward the medal feed port while leaning on the lower side plate when passing between the lower side plate and the upper side plate provided in the medal passage.

As described above, a drop hole is formed in the lower side plate on which the medal rolls while leaning, and the height of the drop hole from the bottom of the medal passage has a predetermined outer diameter. Since the diameter of the medal is smaller than the diameter of the medal, the medal having a predetermined size or a diameter larger than the medal has the uppermost part of the medal located above the upper edge of the drop hole when passing through the drop hole formed in the lower side plate. Therefore, it passes through the position of the drop hole while leaning on the lower side plate, is discharged from the medal feeding port, and is put into the game.

On the other hand, a small-diameter medal having a size smaller than a predetermined size, when passing through the drop hole formed in the lower plate, leans on the lower plate because the top of the medal is located below the upper edge of the drop hole. The upper part of the medal falls into the fall hole without being able to do it. On the bottom side of the upper side plate facing the drop hole, a selection medal exclusion port for excluding selected small-diameter medals from the medal passage is provided opening downward.

[0006] For this reason, among medals rolling in the medal path, small-diameter medals having an outer diameter less than a predetermined size are inclined from the upper side to the outside of the drop hole, and at the same time, the lower side of the medal is disengaged from the bottom, and is sorted. It is eliminated from the medal passage through the medal exclusion opening.

[0007]

However, in the above-described conventional medal selector, when a small-diameter medal having an outer diameter smaller than a predetermined size naturally flows down, the medal can be reliably removed from the medal passage. In the case where the small-diameter medal is sent inside, there is a problem that the small-diameter medal may not be excluded from the medal path.

That is, since a small-diameter medal that is sent vigorously has a large velocity component in the traveling direction, the time required for the small-diameter medal to pass through the drop hole is short, and the small-diameter medal is inclined before reaching the drop hole. The medal itself had passed through the fall hole. In addition, the small-diameter medals may pass near the upper side plate without leaning against the lower side plate, and in this case, the small-diameter medals pass away from the drop hole, so that it is more difficult to be removed from the medal passage. Was.

Therefore, the invention of claim 1 has been made in view of the above-mentioned problems of the prior art, and an object thereof is to provide a predetermined method without increasing the cost and the arrangement space. An object of the present invention is to provide a medal selector capable of reliably selecting small-diameter medals having an outer diameter smaller than the dimension and excluding them from a medal path.

[0010] The invention of claim 2 has the following object in addition to the object of the invention of claim 1 described above. That is, an object of the present invention is to provide a medal selector that can more reliably select small-diameter medals having an outer diameter smaller than a predetermined dimension and can more reliably remove the medals from the medal passage.

[0011]

SUMMARY OF THE INVENTION The present invention is to achieve the above-mentioned object, and its contents will be described below with reference to embodiments shown in the drawings. According to the invention of claim 1, the medal selector 40 is inserted from the medal insertion slot 32.

Alternatively, a medal having a diameter larger than
When passing through the falling hole 63 formed in the game, the player can lean on the lower side plate 51, so that the player passes through the falling hole 63 as it is and is put into the game.

Therefore, a small-diameter medal having an outer diameter smaller than a predetermined dimension is pushed toward the lower side plate 51 having the drop hole 63 by contacting the pushing protrusion 91 when rolling in the medal passage 50. Therefore, small-diameter medals can be reliably selected and eliminated. Further, the medal is reduced in speed in the traveling direction of the medal due to the contact with the push-out protrusion 91, so that there is a time margin for the medal to be inclined. Even so, it is possible to reliably select and eliminate.

According to the second aspect of the invention, in addition to the configuration of the first aspect of the invention, the following operation is achieved. Since the pushing protrusion 91 provided on the upper side plate 52 is formed along the direction of rolling the medals in the medal passage 50, the medals passing between the lower side plate 51 and the upper side plate 52 provided in the medal passage 50 are provided. Is more reliably extruded toward the lower side plate 51.

Therefore, small-diameter medals having an outer diameter less than a predetermined dimension can be more reliably selected and removed from the medal passage 50 more reliably.

An outlet path 36 communicating with 35 is provided. The medals sorted by the medal selector 40 are returned to the player from the payout port 35 via the lead-out path 36. The medal selector 32 has a medal slot 32 as shown in FIG.
A medal passage 50 is provided, in which the medals inserted from above are rolled toward the hopper device 21 so as to be inclined downward. Also,
The medal passage 50 is opposed to the medal passage 50 with a medal passing distance therebetween in the thickness direction of the medal, and the lower side plate is inclined toward the front door 30 in the medal thickness direction.
51 and an upper side plate 52 are provided. The lower side plate 51 forms a lower wall surface of the medal passage 50, and the upper side plate 52 forms an upstream upper wall surface of the medal passage 50.

As shown in FIG. 1, the lower side plate 51 has a lower portion having a width which allows the medal to pass while rolling, for example, 1.5 times or more and 2 times the thickness of the medal. The bent portion is bent to the inside of the main body 20 of the slot machine 10 with a width that does not become too small. The bent portion serves as a bottom portion 53, and a medal passage 50 is formed along the upper surface of the bottom portion 53. As shown in FIG. 1, the lower side plate 51 and the upper side plate 52 constituting both side walls on the upstream side of the medal passage 50 are bent in a wide-angle L-shape on the medal insertion slot 32 side and obliquely upward in the medal receiving port. 54 is open. Further, the lower side plate 51 constituting the medal passage 50
The hopper device 21 is formed to be bent in a wide-angle L-shape opposite to the medal insertion slot 32 side and to open the medal feed port 55 diagonally downward.

As shown in FIG. 1, a portion of the medal passage 50 between the medal receiving port 54 and the medal sending port 55,
Various functional members are attached to the lower side plate 51. This functional member includes, in order from the medal receiving port 54 side, a medal selecting unit 60 for excluding different-diameter medals from the medal passage 50, a medal blocking unit 70 for preventing a predetermined number or more medals from being inserted into the game, and a medal passing. It comprises a passage detection section 80 for monitoring, and these functional members are arranged in a line along the medal path 50, and the whole medal selector 40 is constituted.

First, the configuration of the medal selection unit 60 will be described. As shown in FIG. 4, a pair of bearings 61, 61 protruding in an L-shape toward the front door 30 and facing each other are provided on the lower side plate 51 of the medal selector 60, as shown in FIG. The bearings 61, 61 pass through the center of both bearings 61, 61, and the lower side plate 51
A rotation shaft 62 is provided in parallel with the axis.

As shown in FIGS. 1 and 4, below the bearings 61, 61, a rectangular drop hole 63 extending along the direction of rolling the medals of the lower side plate 51 is provided. It is open through. As shown in FIG. 5, the height of the falling hole 63 from the upper surface of the bottom 53 at the upper edge thereof is set to be smaller than the diameter of the medal A having a predetermined size, and the height of the lower edge from the upper surface of the bottom 53 is a predetermined size. Each is set to be equal to or less than the radius of the medal A. Although not shown, the size of the falling hole 63 in the direction of rolling the medals is set to be sufficiently longer than the diameter of the medal A having a predetermined size.

As shown in FIG. 5, a large-diameter restraining plate 64 for regulating the upper limit of the height of the medal passage 50 is provided on the lower side plate 51 above the drop hole 63 along the medal rolling direction. Drop hole
Screwed at the top of 63. The screw stop position in the height direction of the large-diameter holding plate 64 is set slightly larger than the diameter of the medal A of a predetermined size from the upper surface of the bottom 53 of the lower side plate 51.
Therefore, the large-diameter holding plate 64 prevents medals having a diameter larger than the predetermined-size medal A from rolling. The height of the medal passage 50 can be changed in accordance with the size of the medal A of a predetermined size by changing the screwing position of the large diameter suppressing plate 64 in the height direction.

As shown in FIG. 1, an upper side plate 52 facing the lower side plate 51 with the medal passage 50 interposed therebetween is fixed to the rotating shaft 62 from the near side in the figure. The upper side plate 52 has a lower side abutting against an end face of the bottom portion 53, forms an upper wall surface of the medal passage 50 from the medal receiving port 54 to the medal selecting section 60, and is formed so as to be able to open downward around the rotating shaft 62. ing.

As shown in FIGS. 1 and 5, the upper side plate 52 reaches the bottom 53 at the medal receiving port 54 side. The medal A is cut off to a height of about one-third from the bottom, thereby forming a selective medal rejection opening 90. As shown in FIGS. 1, 4, and 5, the upper side plate 52 above the selection medal exclusion port 90 has a horizontally long extrusion protrusion 91 along the medal rolling direction of the medal passage 50.
Are formed so as to protrude inside the medal passage 50 with the same thickness. As shown in FIG. 5, the extrusion protrusion 91 is positioned so that the height from the bottom 53 is equal to or larger than the radius of the medal A having the predetermined dimension. Upper side plate leaving a gap that can pass
It protrudes from 52. The extrusion protrusion 91 has a semicircular cross section, and both end portions are formed hemispherically. Note that the push-out protrusion 91 may be provided so as to protrude from the upper side plate 52 in a thick shape. Further, the cross section of the extrusion protrusion 91 does not necessarily have to be semicircular, but when a medal rolling in the medal passage 50 collides, the medal smoothly moves to the lower side plate.
Preferably, the shape is extruded toward 51.
Further, the push-out protrusion 91 does not necessarily have to be formed horizontally long along the medal rolling direction of the medal passage 50, and may be, for example, a hemispherical protrusion protruding toward the inside of the medal passage 50. .

On the side opposite to the upper side plate 52 with the rotating shaft 62 interposed therebetween, as shown in FIG. . The pushing member 92 is fixed to the upper side plate 52, and rotates together with the rotation of the upper side plate 52. In a state where the upper side plate 52 is in contact with the bottom 53, the lower end of the pushing member 92 is located outside the drop hole 63 as shown in FIG. It is put in and out of the drop hole 63 and is formed so as to be able to appear and disappear in the medal passage 50.

As shown in FIGS. 4 and 5, on the outer surface of the pushing member 92, a pressing portion 93 which is pushed down in conjunction with the advance / retreat of the cancel button 33 provided on the front surface of the front door 30 is provided substantially horizontally. With the pressing down of the pressing portion 93,
The pushing member 92 and the upper side plate 52 rotate about the axis. As shown in FIGS. 4 and 5, the pushing member 92 and the upper side plate 52 are urged by a coil spring 65 wound around the rotating shaft 62 in a direction in which the upper side plate 52 is pressed against the end surface of the bottom 53. Thus, normally, the upper side plate 52 is positioned substantially parallel to the lower side plate 51 and the pushing member 92
Is located outside the drop hole 63.

Next, the structure of another functional member will be described. The medal blocking unit 70 is provided along an electromagnetic solenoid (not shown) fixed to the back surface of the lower plate 51 and a back surface of the lower plate 51. As shown in FIG. It is formed by projecting the piece 71, and turns on / off the electromagnetic solenoid.
When the block member 71 is turned off, an operating member (not shown) that protrudes and retracts into the medal passage 50 from a slit 72 provided in the lower side plate 51 and a medal passage from the distal end of the operating member to the medal receiving port 54 side. Medal passage 50 located above 50
And a holding side plate 73 whose upper end is axially fixed so as to be able to open downward. This medal blocking part 70
Excessive medals larger than a predetermined number that can be inserted in one game are eliminated from the medal passage 50 by colliding with a block piece 71 protruding into the medal passage 50 from the lower side plate 51 side. This is for guiding to the payout port 35 provided.

Although not shown, the operating member has a spring on the side opposite to the block piece 71, and is urged to project the block piece 71 into the medal passage 50 when the electromagnetic solenoid is OFF. As shown in FIG. 1, the pressing side plate 73 has a weight 74 on the upper surface side thereof, and has an appropriate weight to prevent the medal from jumping out of the medal passage 50 on the way to the block piece 71. At the end face of the bottom 53.

As shown in FIG. 1, the passage detecting section 80
For example, two photocouplers 81, 81 having a U-shaped cross section having a light emitting unit and a light receiving unit opposed to each other and having a detection optical axis facing the medal path 50 from above are arranged adjacent to each other. It is. Each photocoupler 81 detects the passage of a medal sent without being blocked by the medal blocking unit 70. The reason why the two photocouplers 81 are adjacent to each other is not only to detect the number of medals, but also to monitor whether or not medals pass normally. That is, the photocoupler 81
By providing two adjacent medals, it is possible to detect the passing speed and the passing direction of the medals, whereby it is possible to detect not only the number of medals but also the passing of an unauthorized medal moving in the opposite direction.

As shown in FIG. 1, the lower side plate 51 and the upper side plate 52 in the medal receiving opening 54 are open outward toward the medal insertion slot 32, so that the inserted medals are easily received. Further, the upstream end of the lower side plate 51 of the medal receiving port 54 is bent in an L-shape toward the medal passage 50 so that the medals received from the medal receiving port 54 are guided to the medal selection unit 60 side. The upstream side of the medal passage 50 is closed.

On the other hand, as shown in FIG. 1, on the medal feeding port 55 side, the sliding surface of the medal of the lower side plate 51 itself is
It is formed to be bent shallowly inside the main body 20 of the slot machine 10. As a result, medals can be reliably sent from the medal selector 40 toward the center of the hopper tank 22 of the hopper device 21. Next, the operation of the medal selector 40 formed as described above will be described.

The medals inserted by the player through the medal insertion slot 32 are guided to a medal receiving opening 54 formed to extend outward, enter the medal selector 40, and are first sent to the medal selection unit 60. In the medal selection unit 60, medals having an outer diameter different from the predetermined size are selected. Hereinafter, the sorting operation will be described in three cases, that is, when the sent medals are smaller than the predetermined size, when the medals are larger than the predetermined size, and when the sent medals have the predetermined size.

First, the case where the medal is a small-diameter medal B smaller than a predetermined size will be described. If the medal is less than the specified size,
When a small-diameter medal B whose diameter is less than the distance from the upper surface of the bottom 53 to the upper edge of the drop hole 63 is sent to the medal selection unit 60, the small-diameter medal B moves on the bottom 53 toward the lower side plate 51. Rolls inside the medal passage 50 while hanging, but since the outer diameter is smaller than a predetermined size, the top is not supported by the lower side plate 51 at the drop hole 63, and from the drop hole 63 toward the outside of the medal passage 50 Fall down. At the same time, the lower side of the small-diameter medal B in contact with the bottom 53 is swung out of the medal passage 50 and comes off the bottom 53. As a result, the small diameter medal B is at the bottom
The support by the upper side plate 52 is lost as shown in FIG.
From the selection medal exclusion port 90, and then returned to the player from the payout port 35.

Further, the small-diameter medal B vigorously flows in the medal passage.
In the case where the small-diameter medal B has a large velocity component in the traveling direction when it is sent to the inside of the medal passage 50, the small-diameter medal B may pass through the medal passage 50 near the upper side plate 52 without leaning on the lower side plate 51. is there. In this case, the small-diameter medal B collides with the end of the pushing protrusion 91 provided on the upper side plate 52 and is pushed out toward the lower side plate 51. As a result, as shown in FIG. 7, the small-diameter medal B is pushed down from its upper side toward the falling hole 63, and the falling hole
The small-diameter medal B falls outward from 63, and its lower side comes off the bottom 53, and the small-diameter medal B falls downward.

At this time, the stronger the force of the medal, the greater the force to be pushed down to the falling hole 63 side. In addition, the closer to the upper side plate 52, the longer the medal is in contact with the pushing protrusion 91, so that the velocity component in the medal traveling direction is greatly attenuated and reaches the opening of the drop hole 63 accordingly. There is time margin. This means that the pushing protrusion is proportional to the medal's momentum and the distance from the drop hole 63.
91 means that the action of trying to make the medal reach the falling hole 63 works strongly. Therefore, by the pushing projection 91, at any passing position in the medal passage 50,
In addition, no matter how fast or slow a medal is sent, a small-diameter medal B having a diameter smaller than a predetermined dimension can be reliably dropped to the payout port 35 side.

Further, since the push-out projection 91 is provided along the direction of rolling the medals in the medal passage, the small-diameter medal B passing through the drop hole 63 can be moved to the lower side plate while passing through the drop hole 63.
51, that is, it is pushed down toward the falling hole 63, so that the small-diameter medals B can be reliably selected and eliminated. Next, the large-diameter medal C whose diameter is larger than the distance from the upper surface of the bottom 53 to the lower end of the large-diameter holding plate 64 will be described.

When the large-diameter medal C is sent to the medal selection section 60, the large-diameter medal C rolls in the medal passage 50 in the same manner as described above. Since the upper peripheral surface of the medal C hits the end surface of the large diameter holding plate 64,
It cannot roll any more in the medal passage 50 and stops in the medal selector 60. At this time, the player notices that the inserted large-diameter medal C does not cause a reaction in the gaming machine, and presses the cancel button 33 provided on the front surface of the front door 30 considering that the medal may be jammed. Then, the pushing member 92 linked to the cancel button 33 rotates together with the upper side plate 52, and as shown in FIG.
The lower end of 92 pushes the stopped large-diameter medal C by projecting from the drop hole 63 into the medal passage 50. For this reason, the large-diameter medal C is forcibly removed from above the bottom portion 53, and falls downward from the sorting medal exclusion port 90 provided between the upper side plate 52 and the bottom portion 53 by the rotation of the upper side plate 52. Thereafter, the dropped large-diameter medal C is returned to the player from the payout port 35 as described above.

Note that this forcible return of medals is not limited to the case where a large-diameter medal C having a diameter larger than the predetermined-size medal A is sent to the medal selection unit 60. That is, even when the medal A of the predetermined size or the small-diameter medal B having a diameter smaller than the predetermined size is sent to the medal selecting unit 60, the medals A to C can pass through the medal selecting unit 60 for some reason. If the player gets stuck without pressing the button 33,
The medals A to C are similarly returned to the player.

Next, the case where a medal A of a predetermined size is sent will be described. When the predetermined-size medal A is sent, as shown in FIG. 5, the predetermined-size medal A has an upper portion above the drop hole 63 when passing through the drop hole 63. Since it is supported by the portion, it passes through the medal selection unit 60 and is sent to the next medal blocking unit 70.

When the medal is allowed to be taken in and the electromagnetic solenoid of the medal blocking unit 70 is energized, the block 71 of the operating member is retracted outside the medal passage 50. Therefore, the medal A sent from the medal selection unit 60 rolls in the medal passage 50 without being blocked by the medal blocking unit 70, and is counted by the next passage detection unit 80. Thereafter, the medals are sent out from the medal outlet 55 into the hopper tank 22 of the hopper device 21.

On the other hand, when a predetermined number of medals that can be used during one game is already counted by the passage detection unit 80, or the start button 34 provided on the front surface of the front door 30 is pressed. If a medal is further inserted between the end of the game and the end of the game, the power supply to the electromagnetic solenoid of the medal blocking unit 70 is cut off. in this case,
The excited electromagnetic solenoid stops attracting the operating member, and the operating member is pressed against the lower side plate 51 by the bias of a spring (not shown), and the block piece 71 at the tip end thereof is pressed.
Project into the medal passage 50. After that, medal selection section 60
The medals A sent from the cradle collides with the block pieces 71 and can be turned to the outside of the medal passage 50, so that the medals A come off the medal passage 50 and are guided to the lower payout port 35 as in the previous term. In this manner, the loading of medals of a predetermined number or more or medals during the start of the game is prevented.

[0047]

Since the present invention is configured as described above, it has the following effects. Claim 1
According to the invention described above, a small-diameter medal having an outer diameter smaller than a predetermined dimension contacts the extrusion protrusion provided on the upper side plate when passing between the lower side plate and the upper side plate provided in the medal passage. As a result, it is pushed out toward the lower side plate having the drop hole.

Therefore, a small-diameter medal having an outer diameter less than a predetermined dimension can be reliably selected and eliminated. Further, in particular, even for a small-diameter medal that is vigorously inserted into the medal passage, the speed component in the traveling direction of the medal is attenuated by the contact with the push-out protrusion, and the time required for the medal to tilt toward the drop hole is reduced. Since there is a margin, it is possible to reliably select and eliminate.

According to the second aspect of the present invention, the following effects can be obtained in addition to the effects of the first aspect of the present invention. Since the extrusion protrusion provided on the upper side plate is formed along the direction of rolling the medals in the medal passage,
The medals passing between the lower side plate and the upper side plate provided in the medal passage are more reliably pushed toward the lower side plate.

Therefore, a small-diameter medal having an outer diameter smaller than a predetermined dimension can be more reliably selected and more reliably removed from the medal path.
