Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball discharging device for a pachinko machine.

[0002]

2. Description of the Related Art As a ball discharging device for a pachinko machine, a back gutter for supplying a pachinko ball from a storage tank to a supply tray and a receiving tray on the front side of the machine is provided on a back mechanism board of the machine.
It is well known that a stopper mechanism that restricts the flow of pachinko balls in the middle of the discharge gutter is provided, and when a discharge request for prize balls etc. is generated by electronic control, the stopper mechanism is opened for the operating time according to the number of requests. ing.

[0003]

By the way, in such a discharging device, compared with the conventional one in which the movable gutter is swung (discharging operation) through a mechanical structure, a link interlocking with winning of a game ball, and the like. , It is possible to discharge the game ball with good responsiveness to winning a prize, that is, to speed up the discharge, but since the mechanical structure of the stopper mechanism is simple, for example, wire etc. intrudes from the supply tray or the tray on the front side of the pachinko machine. Therefore, I was a little worried about the function of preventing fraudulent attempts to open the stopper mechanism.

In order to prevent the pachinko balls (discharge balls) from jumping out of the supply tray or the receiving tray on the front side of the machine as the discharge processing becomes faster, the flow speed of the balls from the stopper mechanism is moderate. It is necessary to form the flow path in a meandering shape so as to attenuate it, but in that case there was a problem that the wall surface part where the sphere hits violently at the bent part of the flow path may be worn and damaged early. .

Therefore, the present invention aims to solve such a problem by a simple countermeasure.

[0006]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a discharge gutter for supplying a pachinko ball from a storage tank provided on a back mechanism panel of a pachinko machine to a supply tray and a receiving tray on the front side of the machine, and a middle of the discharge trough. In a ball discharging device provided with a stopper mechanism that regulates the flow of pachinko balls, a bent portion that forms a meandering downstream channel of the discharge gutter so as to appropriately dampen the momentum of the pachinko balls that fall from the stopper mechanism. , A normally closed foreign matter intrusion prevention member that can be opened and closed only on the downstream side to allow the ball to flow down from the closed position that blocks the discharge gutter, and a pachinko ball from the upstream side at the flow path bent portion of the stopper mechanism downstream. A wall surface member is provided, which is configured to be replaceable in a region that hits vigorously with a member having excellent wear resistance.

[0007]

According to this, when the pachinko ball falls from the stopper mechanism, the pachinko ball meanders in the downstream flow path of the discharge gutter, pushes the foreign matter intrusion prevention member open, and is discharged to the supply tray and the receiving tray on the front side of the machine. Therefore, the momentum of the sphere is appropriately attenuated mainly at the bent portion that changes the direction of the flow path. In this case, since the area where the balls hit vigorously at the bent portion can be replaced with a wear-resistant wall member, it is possible to secure good durability of the gutter corresponding to speeding up the discharge process and to use it for a long time. There is an economic merit that only this member needs to be replaced when the wall member is worn or damaged due to.

Further, since the normally closed foreign matter invasion preventing member can open and close the middle of the flow path only to the downstream side, in other words, to block the upstream side so as not to open and close, it does not obstruct the flow of the pachinko ball. It is possible to effectively prevent a fraudulent act of opening a stopper mechanism by intruding a wire or the like from the downstream side. The bent portion of the flow path also helps prevent the entry of foreign matter.

In FIG. 1, reference numeral 16 denotes a winning ball payout unit for discharging the winning balls in the derived trough 6 one by one each time the discharging of the winning balls is completed, and a detector and a payout mechanism for detecting the presence or absence of the winning balls inside the winning ball payout unit. Will be housed. Reference numeral 17 is an emission control circuit for processing the discharge of prize balls based on the detection of the presence of a ball by the prize ball detector and the discharge of the loan balls based on a command from the ball lending machine, 18 is a control circuit of the hitting ball launching device 4, and 19 is a game situation. Is a speaker for outputting various game sounds corresponding to, and 20 is a relay board for exchanging signals with the ball lender side.

The ball discharging device 21 is a guide gutter unit 22 for flowing down pachinko balls from the ball storage tank 7 while rectifying the pachinko balls into two rows, a discharging unit 23 forming an upstream part (parallel path) of the discharge gutter, and a flow path switching. Units 24 are provided, and each unit is detachably assembled at a predetermined position on the back mechanism board 3. In the assembled state, the discharge unit 23 and the flow path switching unit 24 are arranged from the downstream portion of the guide gutter unit 22.
A cover (not shown) is integrally provided to cover them. Reference numerals 25A and 25B denote locking holes for attaching the cover.

As shown in FIGS. 3 and 4, the ball storage tank 7 is integrally molded in a box shape with a synthetic resin, and an opening 27 is formed at the lowermost portion of the inclined bottom wall 26 thereof. The inclined bottom wall 26 is composed of a central inclined surface 26A that converges from the right side of the tank to the opening 27 and an inclined surface 26B that forms both wings of the central inclined surface 26A. Is provided. In addition, in order to equalize the load of the pachinko balls to the entire inside of the tank 7, a raised portion 29 is formed in which a part near the opening where the depth increases increases to the bottom.

The movable wall 28 is fitted to the inclined bottom wall 26 of the tank 7 so as to close the excision opening 30 that opens, and the inclined bottom wall 2
On the upper end side with respect to 6, a lever-shaped projection 31 is rotatably attached to an attachment piece 32 on the lower surface of the tank via a shaft 33. The lower end of the movable wall 28 is bent to the outside of the tank 7 in an L shape, and a small protrusion that restricts the movable wall 28 from entering the inside of the tank is formed on an arcuate curved surface centered on the shaft 33 of the bent portion 34. 35 is formed. A spring 36 urges the movable wall 28 to the regulation position of the small protrusion 35. The spring 36 is attached around the shaft 33 with both ends abutting against the movable wall 28 and the lower surface of the tank 7.

Therefore, when the tank 7 is filled with a predetermined amount or more of pachinko balls, the movable wall 28 is pushed down by the load so as to form a part of the inclined bottom wall 26, and at this time, the lever-like protrusion 31 on the upper end side. Locks on the bottom surface of the tank and restricts further rotation. When the number of pachinko balls in the tank 7 decreases from this state, the movable wall 28 is gradually pushed up to the inside of the tank by the spring force, and this time the small projection 35 on the lower end side is locked to the lower surface of the tank and further rotated. Regulate.

In order to attach the ball storage tank 7 to the back mechanism board 3, a recessed recess 37 for receiving the front side of the tank 7 is formed in the upper portion of the back mechanism board 3 as shown in FIG.
Boss 38 that protrudes vertically from the board on both sides of 7.
Are arranged three at the top and bottom. On both sides of the tank 7, flanges 39 having a connecting structure 40 for the boss portion 38 of the back mechanism board 3 are provided.

As shown in FIGS. 6 and 7, the coupling structure 40 includes substantially cylindrical engaging portions 40A and 40C for holding the upper and lower boss portions 38A and 38C, and a seat to be fitted to the intermediate boss portion 38B. A clip 40a as a fixing member for fixing the surface portion 40B and the engagement hole 38a of the upper boss portion 38A (when the knob on the rear surface side of the flange is pushed and pulled, the locking portion on the front surface side expands and contracts), and the insertion hole of the lower boss portion 38C. A pin (40c) for 38c is provided, and a screw (not shown) as an auxiliary fixing member for connecting the intermediate boss portion 38B and the seat surface portion 40B is provided.

Therefore, the tank 7 can be fixed to the back mechanism board 3 by the connecting structures 40 on both sides in a state where the front surface side is housed in the recess 37. In this case, all the engaging portions of the coupling structure 40 and the corresponding boss portions 38 are fitted in the vertical direction of the board surface, so that the load of the pachinko balls stored in the tank 7 can be sufficiently supported. Further, since the tank 7 can be attached or detached from the direction perpendicular to the board surface of the back mechanism board 3, it is not necessary to waste space on the board surface for these operations. Since the load in the tank 7 does not act in the direction of removing the tank 7, if the engagement force of the clip 40a is sufficient to prevent slipping off, it is not necessary to purposely use a screw as an auxiliary fixing member.

The ball shortage detector 12 of the ball storage tank 7 is turned on and off by opening and closing the contact, and is arranged on the back mechanism board 3 side with the operator 41 of the contact facing the movable wall 28 side of the tank 7. In this case, the detector 12 is provided with two lamps for indicating that there is a lamp for indicating a shortage of balls in the tank (for example, provided at the upper part of the front frame of the pachinko machine) and an operating mechanism for replenishing the tank with pachinko balls, because the control system is different. They are arranged side by side and mounted in the storage section 42 formed below the recess 37 of the back mechanism board 3 (see FIG. 5).

These detectors 12 are turned off when the amount of pachinko balls stored in the tank is equal to or greater than a predetermined value and the movable wall 28 is pushed down to the regulating position of the lever projection 31, and the pachinko balls are stored. When the amount decreases and the movable wall 28 is pushed up by the spring 36, it is turned on.

By the way, regarding the positional relationship between the detector 12 and the movable wall 28, when the actuator 41 of the detector 12 can directly contact the lower surface of the movable wall 28, the movable wall 28 is attached when the tank 7 is attached. Since there is a risk that the operator touches the operator 41 and damages it, the detector 12 is installed in the back mechanism board 3 as shown in FIGS.
Of the movable wall 28 immediately below the front surface of the tank 7
The position is set so that it does not overlap with.

In this case, the accommodating portion 42 of the detector 12 is formed by recessing it from the board surface to a depth substantially the same as the recess 37 of the tank 7, and the detector 12 is attached to the lower surface of the movable wall 28 when the tank 7 is set. A pressing piece 43 extending so as to be suspended from the operator 41 is attached. The tip of the pressing piece 43 is formed in an upward inclined portion 44, which prevents an unreasonable force from acting on the actuator 41 of the detector 12 when the tank 7 is attached.

In FIGS. 3 and 4, reference numeral 45 is an attached member fitted to the side wall for preventing the pachinko ball from spilling backward from the tank 7 when the front frame 2 is opened and closed, and the upper part thereof has many small pieces forested. It is formed like a fence. Also,
Reference numeral 46 denotes a ball seal that hangs down in the parallel path of the guide trough unit 22 and is rotatably supported by a mounting piece 32 on the lower surface of the tank 7 via a shaft 47.

A guide gutter unit 22 for guiding the pachinko balls falling from the opening 27 of the ball storage tank 7 to the upstream part of the discharge gutter 8.
As shown in FIGS. 10 and 11, an upstream portion 50 (guide gutter) that gently flows down the pachinko balls while rectifying the pachinko balls into two rows, and a downstream portion 5 that guides the pachinko balls in a meandering path in the vertical direction.
1 (flow path conversion section), and a flow dividing wall 53 that defines a parallel path 52 is provided in the trough of the upstream section 50. The distribution wall 53 is formed so that its height gradually increases toward the downstream of the gutter (finally rises to a height equal to or larger than the diameter of the pachinko ball).

The downstream portion 51 is formed by assembling the case-shaped first and second flow path constituting members 54 and 55 with the substrate 56 sandwiched therebetween, and the parallel paths 52 of the upstream portion 50 are formed on both sides of the substrate 56 inside thereof. A vertical meandering path 58 is formed that connects via a U-turn path 57. Inside the downstream portion 51, FIG.
2. As shown in FIG. 13, a movable piece 59 that can swing freely in the vertical direction by a shaft 58 installed on the gutter in front of each U-turn path 57.
Then, a detector 60 for detecting the broken state of the pachinko ball in the gutter from the swing of the movable piece 59 is provided. 12 shows one gutter in the downstream portion 51, and FIG. 13 shows the other gutter.

As the detector 60, a gate type optical sensor which allows the movable piece 57 to enter is used, and when the movable piece 59 is pushed up into the gate type sensor 60 by the continuation of the pachinko balls, it turns off and the pachinko ball. When the movable piece 59 descends into the gutter due to the interruption of the flow-down, the device is turned on. The detector 60 is a common wiring plate 61 (connector 6
2) are mounted side by side, and the mounting member 63 on one side is provided with a mounting hole 63 and a lid piece 64 for mounting it in a predetermined position in the downstream portion (see FIG. 11).
Although the movable piece 59 is attached, when the detector 60 is turned on by the lowering of the movable piece 59, it is provided as a discharge standby ball on the downstream side of the movable piece 59 (in the gutter of the two systems) for one lending ball. It is set so that pachinko balls more than the number ejected remain.
Reference numeral 65 denotes a guide plate that suppresses the overlap of the pachinko balls from the upstream portion 50. The guide plate 65 is swingably supported in the vertical direction via the shaft 66 near the entrance of the downstream portion 51, and is slightly covered so as to cover the parallel path 52. A weight 67 is attached to the tip side extending in a warped manner.
Equipped with.

The meandering paths 58 are adjacent to each other in the front-rear direction with the substrate 56 sandwiched therebetween, and are formed so as to be connected to the lower end portions which are opened in a state where they are bent differently and are offset to the left and right. A shutter 68 is provided at the lower end of each meandering path 58 to prevent balls from falling off. The shutter 68 is shown in FIGS.
As shown in FIG. 5, one flat plate is formed into a stepped shape corresponding to the positional relationship between the two meandering paths 58 on the plane, and is supported in the lower end opening portion so as to be slidable (open / close) in the front-rear direction. A spring 69 urges the shutter 68 to the closed position, and the spring 6 is urged by the insertion wall when the shutter 68 is connected to the discharge unit 23 described later.
The slit-shaped fitting hole 7 is located between the meandering paths 58 so that the shutter 68 can be pushed to the open position against the biasing force of the slit 9.
0 is provided. The shutter 68 is assembled together with the spring 69 from a mounting hole formed in the component member 54 on one side, and the spring 69 is provided between the lid member 71 of the hole and the spring receiver 72 of the shutter 68 at the center of the pin 73.
It is supported via a and 73b (see FIG. 11).

The shutter 68 serves as the discharge unit 23.
If there are continuous pachinko balls in the meandering path 58 at the time of separation, the closing operation is performed by pushing them apart. At that time, in order to facilitate smooth insertion between the pachinko balls, the tip of the stepped shape has a blade. Such an inclined surface is formed. Further, the semicircular cutouts 7 are provided at the lower end portions of the two meandering paths 58 so that the pachinko ball located below the shutter 68 and between the discharge unit 23 and the discharge unit 23 does not become an obstacle when the discharge unit 23 is separated.
4 is formed.

In order to attach the guide gutter unit 22 to the back mechanism board 3, a rib 75 for horizontally supporting the load along the gutter is erected at the center of the lower surface of the upstream portion 50 as shown in FIGS. A clip 76a and a screw mounting hole 77a are provided on the rib 75. Further, on the upstream side of the parallel path 52, a flange 78 that abuts the board surface on one trough wall side facing the back mechanism board 3, and on the downstream side in the other trough wall in the depth direction of the trough due to the weight of the pachinko ball. Flange 79 is formed respectively for supporting the bending moment acting. A clip 76b and a screw mounting hole 77b are provided on the flange 78, and a clip 76c is provided on the flange 79. 76d is a clip of the unit downstream portion 51, 7
7d is also a screw mounting hole.

A horizontal support wall 80 on which a rib 75 is placed is projected from the back mechanism board 3 at the mounting position of the guide gutter unit 22. Further, bosses 81, 82 are arranged on the surface facing the rib 75, the flange 79, etc., and these bosses 81, 82
82, engaging holes 81a, 81c, 81d for clips 76a, 76c, 76d or screw holes 82a, 82c, 82d for screws are formed. An engagement hole 81b for engaging with the clip 76b and a screw hole 82b are provided on the surface of the board that contacts the flange 78.

The guide gutter unit 22 is provided with the back mechanism board 3
On the support wall 80 of the rib 75 and the flange 78,
It is attached by connecting with clips 76a to 76d or screws via 79 or the like. In this case, the rib 75 on the support wall 80 with respect to the load in the gutter moves it from the upstream side to the downstream side in the center of the gutter. Therefore, the unit upstream portion 50 can be held at a predetermined inclination angle, that is, the change of the inclination angle with time can be almost completely prevented, and the inclination of the gutter in the depth direction can be effectively prevented. In addition, the upstream side and the downstream side of the parallel path 52 facing the back mechanism board 3, the flange 78 on the one gutter wall side and the flange 7 on the other gutter wall.
Since the clip 76b, 76c and the like support the front and rear in the depth direction at 9, the support rigidity can be further improved against the bending moment due to the weight of the pachinko ball. The clips 76a to 76d have the same configuration as the clip 40a of the ball storage tank 7, and if the engagement force of these clips is sufficient to prevent slipping off, it is not necessary to use screws as auxiliary fixing means. ..

In FIG. 11, a conductive metal plate 90 which also serves as reinforcement of the road surface is attached to the parallel path 52 of the unit upstream portion 50 from the position facing the opening 27 of the ball storage tank 7 to the downstream side. The metal plate 90 is for grounding static electricity or the like of a pachinko ball, and is formed in a strip shape having almost the same width as the road surface, and a plurality of bent pieces 91 are formed on both sides thereof and a grounding connection terminal 92 is integrally formed on one side thereof. To be done. Then, as shown in FIG. 19, the metal plate 90 has slits 9 on both sides of the road surface.
Insert the bent piece 91 into 3 and put the bent piece 9 on the bottom side of the gutter.
It is fixed by bending 1 inward,
At this time, the rib 75 interferes with the bending process. Therefore, in this example, a small opening 94 is provided at the base of the rib 75, and a tool can be inserted from the opposite side by using this opening 94 to facilitate the bending process. It has become. 20 and 21, the slits 93 may be formed in an inclined state that promotes inward bending when the bending piece 91 is inserted, or the inclined projections 95 may be formed on both sides of the rib 75 as well. As a result, the tip end side of the bent piece 91 is separated from the rib 75, which facilitates the subsequent bending process. The connection terminals 92 of the two metal plates 90 are inserted into the slits on the rib 75 side, and are connected to the connecting columns 97 that are erected on the board surface so as to face the notches 96 of the ribs 75 when the guide gutter unit 22 is attached. They are superposed and combined (see FIG. 17).

As shown in FIGS. 22 to 25, the discharge unit 23 includes case-shaped first and second flow path forming members 100 and 101.
In addition, an adjustment path 103 is formed by overlapping the cover member 102, and is connected to the meandering path 58 on the guide gutter unit 22 side. The adjustment path 103 is mainly composed of an upstream vertical portion 104 and a downstream inclined portion 105, and a stopper mechanism 106 (discharging mechanism) that regulates the flow of pachinko balls near the lower end of the inclined portion 105 and discharge immediately upstream thereof. A detector 107 for detecting a sphere is provided.

Here, the adjusting path 103 is connected to the back mechanism board 3 from the introducing section 109 corresponding to the positional relationship on the plane of the lower end of the meandering path 58 to the leading section 110 opening side by side at the same position in the front-rear direction. The flow path is formed so as to bend forward and backward while being adjacent to the left and right in the mounting direction.

The stopper mechanism 106 is composed of a pair of locking members 111 capable of moving forward and backward with respect to the inside of the inclined portion 105, and a solenoid 112 for moving them forward and backward respectively. The locking member 111 is formed in a hook shape at the tip side,
It is swingably supported by a shaft 113 on the side of the inclined portion 105 via its base portion. The tip of the locking member 111 is formed on an arc-shaped sphere blocking surface that matches the swing locus, and the solenoid 112 is pin-coupled to the vicinity of the base (position offset with respect to the shaft 113) via a link 114. ..

A slit 115 corresponding to the tip side of the locking member 111 is formed in the gutter wall of the inclined portion 105. In addition,
Regarding the positional relationship between the locking member 111 and the slit 115 with respect to the inclined portion 105, two pachinko balls are set to be aligned in the inclined portion 105 when the locking member 111 enters.

When the solenoid 112 is in the non-energized state, the locking member 111 enters the inclined portion 105 and its ball blocking surface regulates the flow of the pachinko ball. When the solenoid 112 is energized from this state, the locking member 111 retracts from the inside of the inclined portion 105 via the link 114, allowing the pachinko ball to flow down. Then, when the solenoid 112 is de-energized, the locking member 111 returns to the initial state by the urging force of the return spring 116, enters the inclined portion 105, and again regulates the flow of the pachinko ball (FIG. 2).
4, see FIG. 25).

The discharge ball detector 107 is of a gate type which allows passage of each pachinko ball one by one, and is inclined at a position surrounding substantially the center of the second pachinko ball following the head when the locking member 111 enters. It is installed in the unit 105 and outputs an on / off signal with the discharge of the pachinko ball. Since both sides of the gate type of the detector 107 project to the inside of the gutter wall to some extent in the inclined portion 105, in order to ensure smooth passage of the pachinko ball to the detector 107, the adjustment path 10
On both sides of the gutter wall of No. 3, guide protrusions 120 are formed along the center of the flow path so as to extend at the same height as the protrusion of the detector 107.

By the way, the adjusting path 103 serves to keep the speed and interval of the pachinko ball at the time of flowing down by the vertical portion 104 on the upstream side and the inclined portion 105 on the downstream side, and particularly from the vertical portion 104 to the inclined portion 105. In the bent portion 121, a pachinko ball from the bottom wall 122 of the vertical portion 104 is applied to the inclined wall 123 at a predetermined angle so that the pachinko ball is dropped to the inclined portion 105 at a constant speed and at a constant interval. Since the bottom wall 122 of the vertical portion 104 is greatly affected by the downflow pressure of the pachinko ball, it can be replaced by using a component part of another member having excellent wear resistance and cushioning property.

Reference numeral 130 denotes a switchboard of the solenoid 112 and the detector 107, which includes a connector 131 for connecting to the discharge control circuit 17 side and a connector 132 for connecting to the flow path switching unit 24, which will be described later. Then, the switchboard 130 is set in the storage portion 134 on the rear surface side of the unit 23, and the cover member 13 of the storage portion 134 is attached to the component member 100 on one side.
5 are provided.

Since the discharge unit 23 is attached to the back mechanism board 3, a fitting recess 135 is provided on the right side of the window 9 of the back mechanism board 3 as shown in FIG. The fitting recess 135 is also formed integrally with the space for mounting the flow path switching unit 24, and a flange piece 136 for vertically positioning both units 23 and 24 is provided at the edge of the recess 135, and one side of the recess 135 is provided. Is a locking portion 137 that supports the lower portion of the discharge unit 23.
And the retaining portion 13 that locks the lower portion of the flow path switching unit 24.
8 are provided. Further, a side wall 140 with a claw 139 for locking the rear surface of the unit 23 set in the recess 135 is erected on the surface of the board at the side of the mounting position of the discharge unit 23.

The discharge unit 23 is formed such that the front side in the setting direction is a stepped engagement portion 141 with the fitting concave portion 135 and the lower portion is a stepped engagement portion 142 with the upper portion of the flow path switching unit 24, and the upper surface of the unit 23. An insertion wall 143 that protrudes into the slit-shaped fitting hole 70 of the downstream portion 51 to open the shutter 68 when connecting to the guide gutter unit 22 is provided.

Then, the discharging unit 23 is fitted with the stepped engaging portion 141 on the front side from the rear of the back mechanism board 3 into the fitting recess 135.
And the claws 139 on the side wall 140 from the rear side.
It is attached by locking with. In this case, in the unit 23, the depth dimension (side surface width) is increased by forming the adjustment path 103 so that the flow path is curved forward and backward while being adjacent to the back mechanism board 3 in the left and right directions. The width of the facing surface is substantially the same as the width of the flow path for the left and right adjustment paths 103 and fits straight in the vertical direction, and the stopper mechanism 106 is also positioned at the front and rear position of the flow path, that is, at the position overlapping the adjustment path 103 on the board surface. Can be arranged in a relationship,
Therefore, since the protrusion to the side of the gutter is completely eliminated,
The installation space can be greatly reduced.

By the way, the discharge control circuit 17 (see FIG. 1)
However, on condition that the out-of-ball detector 60 is turned off, the prize balls are discharged when the detector balls in the winning ball payout unit 16 detect the presence of the balls, and the discharge of the loan balls is made in response to the discharge request from the ball lending machine. It is controlled by the ball discharging mechanism 106 when the prize balls are discharged.
The solenoid 112 is driven, and the number of discharged particles is counted based on the signal from the detector 107. When the number of discharged balls reaches a predetermined number of prize balls, the driving of the solenoid 112 is stopped. In addition, the payout mechanism is controlled so that one winning ball is discharged based on a signal from a detector in the payout unit 16 at the end of discharging the winning ball.

Similarly, at the time of discharging the loaned balls, the solenoid 112 of the ball discharging mechanism 106 is controlled to be driven in accordance with the requested number, and at the end of the discharging, a discharge end signal for instructing the ball lending machine to subtract the card balance frequency is executed. It outputs it.

The discharge control circuit 17 is used for the ball discharge mechanism 10.
Control of alternate discharge from only one locking member and simultaneous discharge from both locking members of the solenoid 112 of No. 6 is selectively performed according to the number of discharge requests.

As shown in FIGS. 27 to 31, the flow path switching unit 24 is constructed by arranging and stacking the side members 150 and 151 and the substrates 152 and 153 one by one, and stacking these side members 150 and 151 and the substrates 152 and 153. Between 153, two branch channels 154 connected to the adjustment path 103 of each discharge unit 23 are formed. Note that one branch channel 154 is a gutter wall integrally formed on the surface of the side member 151 facing the substrate 153, and the other branch channel 154 is the substrate 15.
Each of the two side walls 150 is made of a gutter wall integrally formed on the surface facing the side member 150.

Each branch channel 154 is composed of a vertical portion 155 on the upstream side, a meandering portion 156 on the downstream side, and a branch portion 157, and an opening / closing door 158 is arranged at the entrance of the branch portion 157.
Each opening / closing door 158 has two base plates 152, 153 at the lower end base.
It is rotatably supported on both sides of a shaft 159 penetrating through and is connected to each other by a rod 161 penetrating the guide holes 160 of the substrates 152 and 153. A lever member 162 is rotatably attached to the middle of the shaft 159 at a dogleg-shaped central portion, and one end of the lever member 162 is opened and closed via an elongated hole 163.
The connection rod 161 is engaged with the other end, and the other end is pin-connected to the flow path switching solenoid 164 via a link 165.

That is, the opening / closing doors 158 on both sides are integrally driven by one solenoid 164, and in the closed state (when the solenoid 164 is not energized), the branch portion 157 is cut off as shown in FIG. When opened (energization state of the solenoid 164), the branch portion 157 is connected to the vertical portion 155 and the meandering portion 156 side is shut off as shown in FIG. 31 (B). In addition, concave seat portions 166 for locking the opening / closing door 158 at the closed position and the open position are formed on the gutter walls on both sides of the vertical portion 155. Reference numeral 167 represents a return spring of the solenoid 164.

The front side of the flow path switching unit 24 is formed in a stepped engagement portion 168 with the fitting recess 135 of the back mechanism board 3, and like the discharge unit 23, a stepped engagement is performed from the rear side of the back mechanism board 3. It is attached by setting the part 168 in the fitting recess 135 and locking it with the retaining part 138. In this state, the meandering part 156 is connected to the drain gutter 8 on the back mechanism board 3 side (see FIG. 26). ). Further, a connection recess 169 for receiving the stepped engagement portion 142 at the lower portion of the discharge unit 23 is formed between the left and right side members 150 and 151 at the upper portion of the flow path switching unit 24.

Inside the engaging portion 168, the branch portion 15 is provided between the side members 150 and 151 and the substrates 152 and 153, respectively.
7 is provided with a groove 170 having a U-shaped cross section extending downwardly, and a branching portion 157 is connected to a ball-removing gutter (not shown) integrally formed on the front side of the back mechanism board 3 in the fitting recess 135. It is designed to form a road. The fitting recess 1
At the lower end of 35, a hole (not shown) for opening the connecting path to the ball-out trough is provided.

By the way, since the pachinko ball falling from the discharge unit 23 side vigorously hits the bottom wall 171 of the vertical portion 155, the bottom wall 171 is replaceably attached by using a component part of another member excellent in wear resistance and cushioning property. The component 171 includes a delta-shaped portion 172 forming a guide wall of the meandering portion 156 and a block-shaped portion 173 forming a lower wall of the entrance of the branch portion 157, and one delta-shaped portion for each branching channel 154. Portion 172 and block-shaped portion 1
It is fixed between the substrates 152, 153 and the side members 150, 151 via engaging protrusions 174A, 174B that fit with 73. Due to the positional relationship with the opening / closing door 158, the component 171 has an arc-shaped recess 175 surrounding the base of the door 158 on the upper surface of the block-shaped portion 173, and a delta-shaped portion 172.
177 for attaching a gate 176 for preventing intrusion of foreign matter such as wire, which will be described later, between the block and the block-shaped portion 173.
Is formed. Reference numeral 178 is a buffer space formed in the block-shaped portion 173.

The meandering portion 156 moderately attenuates the flow velocity of the pachinko ball, and attempts to open the stopper mechanism 106 of the discharge unit 23 by inserting wire or the like from the supply tray or the tray on the front side of the pachinko machine 1. Although a fraud prevention function is also provided, in this case, in order to achieve more complete fraud prevention, a foreign matter intrusion prevention gate 176 is provided to block the downstream bent portion of the meandering portion 156 from above. The prevention gate 176 is formed by the cutout portion 1 of the component 171.
One end located within 77 is rotatably supported via a shaft 179, and the cutout portion 1 extends from the closed position in which it hangs down by its own weight.
Within the range within 77, the gutter is opened only in the downward rotation, that is, in the direction in which the pachinko ball flows down. It should be noted that the rotation of the prevention gate 176 from the closed position to the upstream side is prevented by the cutout portion 17.
It is regulated by the locking step portion 180 between the inner surface of 7 and the gutter wall.

In addition, a groove 181 deeply tangentially formed in the upper portion of the outer wall of the curve is formed in the bent portion on the upstream side of the meandering portion 156, and the tip of the groove 181 is formed with respect to a wire or the like which enters from the downstream side. It is designed to stop the invasion to the upstream side.

Since the discharge unit 23 and the flow path switching unit 24 have the solenoids 111, 112, and 164 built therein, respectively, the heat dissipation holes 19 are provided at their installation portions.
0 is formed (see FIGS. 22 and 28). Further, the flow path switching unit 24 is provided with a cleaning hole 191 for removing dust accumulated in the meandering portion 156 at the time of maintenance and inspection.

By the way, the shunt channel 154 of the channel switching unit 24 is branched in the front-rear direction with respect to the back mechanism board 3, and constitutes a groove 170 which constitutes a communication path leading to the ball-spilling trough of the back mechanism board 3.
By forming so as to overlap the meandering path 156, the space in the depth direction can be effectively used, and the solenoid 164 for driving the opening / closing door 158 of the branch portion 157 can also be arranged at the front and rear position of the flow path. 156 back mechanism board 3
On the other hand, since the flow paths are formed so as to be bent forward and backward while being adjacent to each other on the left and right, the installation space on the board surface can be significantly reduced as in the case of the discharge unit 23.

The discharge gutter on the side of the back mechanism board 3 is formed in the joint flow passage 182 opening to the meandering portions 156 arranged on the left and right sides on the downstream side of the flow passage switching unit 24 as shown in FIG. 32, and the pachinko machine is provided on the upstream side of the joint flow passage 182. 1 Outlet port 183 connected to the front supply plate
Is provided. The downstream side of the joint flow path 182 is also connected to the saucer via a gentle slope 184.

The strength member 1 is provided on the guide wall to the outlet 183.
3, a dish-shaped introduction part 185 for receiving a pachinko ball is provided, and a ball receiver 187 extending obliquely above the introduction part 185 and immediately below an opening 186 with the meandering part 156 is integrally formed on the trough wall.

Accordingly, the pachinko balls from the flow path switching unit 24 drop along the ball receiver 187 to the introducing portion 185, and are first discharged from the outlet 183 to the supply plate, and the supply plate is filled with the pachinko balls. Then, it falls down from the introduction portion 185 and is discharged to the tray through the inclined portion 184.

The back mechanism board 3 is formed with a ball draining gutter which connects to the lower end of the fitting recess 135 by utilizing the recessed space on the front side, and the pachinko ball from the branch portion 157 of the flow path switching unit 24 is played as a game board. Similarly to the out-ball and the winning ball from the payout unit 16, the ball is discharged to the collecting gutter behind the pachinko machine 1.

Incidentally, regarding the discharging operation of the entire back mechanism of the pachinko machine 1, the pachinko balls from the ball storage tank 7 are guided from the guiding trough unit 22 to the discharging unit 23 and enter the trough in the normal state. The stop member 111 regulates the flow-down.

When the game balls enter the prize opening of the game board, all the prize balls enter the collecting gutter on the back side of the game board, are guided to the payout unit 16 below the collecting gutter, and are prevented from flowing down. When the winning ball detector detects that there is a ball, and a discharge request for the prize ball is generated, the solenoid 112 of the discharging unit 23.
Is driven to convert the locking member 111 into the open state for a predetermined operating time.

As a result, the pachinko ball is ejected by the ejection unit 2
3 is discharged to the supply tray or the receiving tray on the front surface of the pachinko machine 1 through the meandering portion 156 of the flow path switching unit 24 and the downstream portion of the discharge gutter 8.
When the count value of the pachinko balls detected by the number reaches the required number, the solenoid 112 is stopped to stop the locking member 111.
Is returned to the closed state.

In this case, the locking member 111 is the adjustment path 103.
As a result, the speed and interval of the pachinko balls flowing down are maintained properly, so the closing operation (entry into the gutter) can be performed easily without biting the pachinko balls, and therefore the occurrence of ejection errors is extremely small. Become.

When the discharge of the prize ball is completed, one winning ball is discharged by the operation of the payout mechanism. When the detector detects the existence of the ball by the next winning ball, a request for discharging the prize ball is generated again. Will be done.

Further, when a discharge request for a loan ball based on a ball lending machine is generated, the solenoid 112 of the discharge unit 23 is controlled in the same manner as described above according to the number of requests, and the locking member 11 is operated.
The loan ball is discharged through 1. In addition, by pushing the ball lending button on the front of the pachinko machine 1, the lending balls can be repeatedly discharged within the range of the balance frequency of the card.

The number of pachinko balls in the ball storage tank 7 gradually decreases with the discharge of prize balls and loan balls,
When the ball shortage detector 12 is turned on by the swing of the movable wall 28, a fixed amount of pachinko balls is replenished in the tank 7.

[0068]

As described above, according to the present invention, the discharge trough for supplying the pachinko balls from the storage tank provided on the back mechanism board of the pachinko machine to the supply tray and the receiving tray on the front side of the machine, and the middle of the discharge trough. In a ball discharging device provided with a stopper mechanism that regulates the flow of pachinko balls, a bent portion that forms a meandering downstream channel of the discharge gutter so as to appropriately dampen the momentum of the pachinko balls that fall from the stopper mechanism. , A normally closed foreign matter intrusion prevention member that can be opened and closed only on the downstream side to allow the ball to flow down from the closed position that blocks the discharge gutter, and a pachinko ball from the upstream side at the flow path bent portion of the stopper mechanism downstream. A wall member that is configured so that the area that hits vigorously can be replaced with a member that has excellent wear resistance can ensure good durability of the gutter that corresponds to high-speed discharge processing, and the wall portion that can be used for a long period of time. Economical merit with respect to wear and breakage may be replaced with this member only is obtained.

Further, since the normally closed foreign matter intrusion preventing member can open and close the flow path only to the downstream side, in other words, to block the upstream side so as not to open and close, it does not hinder the flow of pachinko balls. It is possible to effectively prevent a fraudulent act of opening a stopper mechanism by intruding a wire or the like from the downstream side.
