Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a prize ball outflow restricting device in a pachinko machine, and more specifically, it will be described in more detail. The present invention relates to a prize ball outflow restricting device for loosely restricting the circulation state of prize balls in the discharge route communicated to the.

[Technical background]

In the well-known pachinko machine P as schematically shown in FIG. 9, a glass door 3 and a support plate 4 are both openably and closably attached to the opening front surface of an openable front frame 2 assembled in a machine frame 1. A game board 6 is detachably attached to a holding frame 5 fixed inside the front frame 2, and a game ball is thrown into the ball receiving tray 7 on the front surface of the support plate 4 while the game ball is being shot. When the device 8 is driven in accordance with the operation of the operating portion 8A, the ball striking operation of the device 8 and the ball feeding device 9 set inside the support plate 4 are performed.
According to the cooperation with the ball feeding operation, the game balls are sent one by one to the launch rail 10 on the front surface of the holding frame 5, and then are shot into the game board 6.

In this ball-hit game, the game balls in the game board 6 enter the prizes at the respective positions and are made safe balls, while a predetermined number of prize balls are supplied from the prize ball dispensing section 12 on the mechanism set board 11 on the back side of the front frame 2. The prize balls will be dispensed. After that, the prize balls will be attached from the downstream end outlet of the discharge path 13 formed in the mechanism set board 11 to the ball outlet 14 formed in the holding frame 5 and the inside of the support plate 4. It flows out in the discharge path leading to the ball insertion tool 15 and is discharged to the ball receiving tray 7. Then, after the pachinko balls in the plate are full, the two-stage state in the discharge path (that is, the state where the upper prize balls are placed on the lower prize balls stored along the bottom surface)
It is stored in, and the ball saucer 7 in the progress of the game under this
As the number of pachinko balls in the inside decreases, the stored prize balls in the discharge route are sequentially discharged into the dish. It should be noted that the prize balls are discharged from the discharge path 12 after filling the ball tray 7 and the discharge path.
Is discharged to the lower ball tray 17 through the branch passage 16.

In such a pachinko machine, in order to promptly discharge the prize balls supplied from the prize ball supply unit 12 to the ball tray 7, the bottom surface of the discharge path is inclined downward with a relatively large slope. At the same time, a step is sequentially added according to the front. As a result, the prize balls can quickly flow out with considerable momentum in the discharge path, but at some times, each stepped portion exhibits a jumping state. For this reason, when the number of pachinko balls in the ball receiving tray 7 is still small, the prize balls that have passed through the ball receiving tray may fly out of the plate with too much force, and a technical measure for solving this problem is desired.

[Prior art]

In the background described above, as an example of a measure for solving the above-mentioned “jumping out of the prize ball to the outside of the ball tray”, conventionally, as illustrated in FIG. A pair of mitigation restriction weir pieces 18 that can come into contact with the prize balls are formed to project forward in a slanted manner on both sides of the distance.

[Problems to be solved by the invention]

According to the above-mentioned conventional art, in the prize balls that are passed through the ball outlet 14 into the ball passing tool 15, the prize balls that have once contacted both the dam pieces 18 have their momentum relaxed and the ball receiving tray Although it is possible to effectively prevent the prize balls from jumping out to 7, the prize balls that have passed through the central portion without contacting both the weir pieces 18 may be vigorously discharged into the plate 7 and sometimes jump out. Further, since both of the weir pieces 18 block the prize balls in the upper stage of the ball passing-in device 15, even if the ball receiving tray 7 is still in a state before being full, the ball outlet 14 and the ball outlet 14 from the latter half of the ball passing-in device 15 The prize balls are stored along the discharge path 13, and the player may not be able to enjoy the "satisfaction due to the filling of the balls in the dish". In forming the weir pieces 18 in the upper ball-passing device 15, there are unexpected difficulties in setting items such as position, shape and direction. By the way, when the weir piece 18 is formed on the upstream end inlet side or the downstream end outlet side in the ball passage device 15, ball clogging is likely to occur.

[Purpose of device]

The object of the present invention is to set the prize balls in the discharge path for prize balls extending between the ball outlet on the game board side and the ball passing tool on the support plate side in the normally closed set state of the support plate for the ball saucer. To provide an award ball outflow restricting device with a simple structure that can appropriately control the outflow momentum, thereby maintaining a good outflow state of the award ball and preventing the award ball from scattering outside the dish. With the goal.

[Means for solving problems]

The present invention is a newly proposed "award ball outflow restricting device in which the support plate is opened / closed" in order to solve the above-mentioned conventional problem, and is provided on the lower side part on the game board side set inside the front frame. While the ball outlet communicating with the downstream end outlet of the discharge path connected to the prize ball feeding portion on the back side of the game board is formed, on the back surface of the support plate mounted on the front side of the front frame near the opening / closing fulcrum portion. In the normal closed set state of the support plate, the ball inlet connected to the upstream portion of the ball tray is formed, and the rearward inlet of the upstream end of the ball outlet is opposed to the forward outlet of the downstream end of the ball outlet. , An up-and-down regulating member that can communicate with each other at a required facing interval and that can come into contact with and separate from the displacement guide member formed on the front side of the ball outlet on the back side of the ball-passing device is vertically displaced. It is freely attached and always urged in one direction, and the lifting regulation member The first and second restricting rods located at the entrance of the ball insertion device are arranged in parallel in the vertical direction with a circulation interval that is appropriately larger than the diameter of the ball, and with respect to the elevating restricting member, closing of the support plate. In the set state, the first and second restricting rods are displaced to a predetermined position with respect to the entrance of the ball-passing tool by being displaced in the anti-biasing direction while being in contact with the displacement guide member and one of the restricting rods is displaced. The rod is held in the middle part of the entrance where it can come into contact with the prize ball, and when the support plate is opened, the rod is separated from the displacement guide member and is returned and displaced in the urging direction.

It is possible to communicate with the outlet 14b of 4 and the forward facing outlet 15b at the downstream end is communicated with the dish portion 7a of the ball receiving tray 7 on the front surface of the support plate 4 with appropriate steps.

In the side outlet 13a and the ball outlet 14 of the main discharge path 13 and the ball passing tool 15, the bottom surface of the prize ball circulation surface area is the 4.6th ball.
As shown in the figure, it is inclined forward with a substantially constant slope, is provided with a required step, and the width of the distribution surface area is gradually widened as shown in FIG. Then, under the condition that the support plate 4 is held in a normal closed set state, the inlet 15a of the ball passage member 15 communicates with the outlet 14b of the ball outlet 14 with a required facing distance (about 3 to 4 mm). The case of being held in is illustrated.

In the prize ball outflow restricting device of the present example, which is carried out on the prize ball discharge path described above, the ascending / descending restricting member 21 of a form capable of interlockingly changing in response to the opening / closing change of the support plate 4 is inserted into the ball. Ingredient
It is attached to 15. This lifting regulation member 21 is
The main purpose is to relax the distribution of prize balls from the ball passing device 15 to the ball passing device 15, and also to prevent the prize ball from spilling from the entrance 15a of the ball passing device 15. The first and second tilting arms 22.23 pivotally mounted in a cantilevered horizontal direction using the support pins 24 at the upper and lower positions of the above, and the free ends of the arms 22.23 of each set are laterally connected to the outside of the entrance 15a. The upper and lower first and second regulating rods 25.26 positioned at and the pair of vertical support rods 27 connected to both ends of both regulating rods 25.26 form a four-bar parallel link mechanism. Then, the entire body is always urged in one direction (upward in the drawing) by using urging means 28 (indicated by a torsion spring attached to the support pin 24), and is formed on both sides of the ball insertion device 15. It is adapted to be retained at a predetermined position on the urging side by being locked by the formed projection.

As a means for changing the elevation of the entire elevation regulating member 21, the third regulation rod 30 is connected between the upper ends of the vertical support rods 27 on both sides, while the outlet 14b of the ball outlet 14 is connected. A transition guide piece 31 is projected on the upper part of the support plate 4, and when the support plate 4 is opened and closed, the third guide rod 30 moves the transition guide piece 31.
As the member 21 can be displaced within a range of contacting the slanted guide surface 32 formed on the lower edge of the lower member, the entire member 21 is elastically displaced to the downward tilted position and the upward tilted position. The tilting arm 2 above
The 2.23 and the vertical support rods 27 are both made of a thin metal material, and the control rods 25.26.30 are both made to have the same size (diameter and length) as the linear material and are appropriately larger than the diameter of the ball. It is held in parallel in three stages with a distribution distance G for use.

Further, in this example, a ball receiving member 33 made of a synthetic resin is attached to the lower front portion of the ball outlet 14 in addition to the above-described lifting restriction member 21. The ball receiving member 33 is for receiving prize balls spilling from the ball outlet 14 when the support plate 4 is opened, and is fixed to the front surface of the launching plate portion 5a of the holding frame 5 with screws or the like, and the bottom plate portion. Vertical wall 33b standing on the front edge of 33a
However, it is formed so as to face the front surface of the launching plate portion 5a and not interfere with the lower portion of the ball penetrating tool 15. The bottom plate portion 33a is inclined downward toward the center of the launching plate portion 5a.
A passage 34 formed by the front surface of the launch plate portion 5a and the vertical wall portion 33b and the vertical wall portion 33a communicates with the lower ball tray 17 side.

Further, a rectangular ball stopper plate 36 made of soft synthetic resin is attached to the vertical wall portion 33b of the ball receiving member 33 so as to be tiltable. This ball stop plate 36 is for directly hitting the winning ball spilling from the ball outlet 14, and the shaft support pieces 37 formed on both sides of the lower end thereof and the shaft support pieces formed inside the vertical wall portion 33b. 35
Is supported so as to be tiltable in the front-rear direction with respect to a support shaft 38 that is passed laterally between and with the urging means 39.
A twisting spring (shown in the drawing) is used to constantly urge the user in the forward standing direction to tilt and change the ball outlet 14 into the close-inclined state and the spaced-apart raised state. In addition, ball stop plate
36, the locking pieces 40 protruding on both sides thereof are locked to the vertical wall portion 33b to be held in an upright state, and the upper end thereof is positioned in front of the ball outlet 14 and at the lower stage portion of the outlet 14b.

In the prize ball outflow regulation device of this example configured as described above,
Regulation of the circulation state of prize balls and the outside of the prize ball by means of a lifting regulation member 21 whose state is changed in relation to the opened / closed state of the support plate 4 (displacement of the ball passage tool 15 to the ball outlet 14 in the perspective direction). Can be prevented from scattering.

Then, looking at the state of the apparatus of this example when the support plate 4 is in the closed set state, as shown in FIG. 3, in the elevating / lowering restricting member 21, the third restricting rod 30 of the displacement guide piece 31 on the ball outlet 14 side is provided. According to being pushed down along the inclination of the guide surface 32, as shown in the drawing, between the inlet 15a of the ball passing-in tool 15 and the outlet 14b of the ball outlet 14, the first regulating rod 25 is at the lower end position,
Further, the second restriction rods 26 are held at the middle positions, respectively. The ball stopper plate 36 of the ball receiving member 33 is held in a state of tilting and changing clockwise in the drawing while being in contact with the rear lower end portion of the entrance 15a of the ball passing tool 15 as shown in the drawing.

Therefore, in such a state, when the discharge state of the prize balls supplied from the prize ball supply unit 12 is observed, as can be understood from FIG. 4, the side outlet 13a of the discharge path 13 to the ball outlet 14 and the ball passage Tool 15
In most of the cases, the prize balls coming out of the contact balls collide with or collide with the second restriction rod 26, the flow momentum thereof is relaxed, and the prize balls enter the ball insertion tool 15 from below or above the restriction rod 26. After that, the flow gradient of the tool 15 is used to quickly flow out and be discharged into the ball receiving tray 7, and the prize balls in the tray 7 are reduced in their momentum and jump out of the tray. Suppressed.

After the pachinko balls in the ball tray 7 are full, the newly dispensed prize balls cannot be discharged into the bowl, but are reversed from the ball passing tool 15 to the ball outlet 14 in the opposite direction. And it will be sequentially stored across the lateral exit 13a of the discharge path 13, in most cases, initially presents a one-step state along each outflow bottom, after that, prize balls overflowing from the lateral exit 13a, It is pushed out while being stored in a two-stage state on the lower storage prize ball. And from the ball outlet 14 in the ball passing tool 15,
The prize balls pass through the flow interval G between the second and third control rods 26.30 and enter the upper portion (two-stage portion) of the ball passing tool 15 and are stored therein. In addition, if the number of pachinko balls in the ball receiving tray 7 gradually decreases in the course of the game, the stored prize balls in the ball passing device 15 are discharged from the outlet 15b into the plate portion 7a so as to be pushed out, and the ball outlet 14 following this The stored prize balls in the discharge path 13 are also sequentially slid out along the circulation bottom surface and discharged to the plate 7.

On the other hand, FIG. 6 shows the state of the apparatus of this example when the support plate 4 is opened forward for inspection and adjustment of the front side of the launching plate portion 5a and the inner surface side of the support plate 4. As described above, in the elevating / lowering restricting member 21, as soon as the third restricting rod 30 is separated from the guide surface 32 of the displacement guide piece 31, the biasing means 28 is used to instantly return to the upward tilt, as shown in the drawing. The first restricting rod 25 is located at the lower step position with respect to the entrance 15a of the ball passing device 15, and the second restricting rod 26 is located at the upper step position with respect to the entrance 15a (both are about the radius of the sphere compared to the position shown in FIG. 4). (Above)
Are held respectively. As a result, the prize ball will be the entrance of the ball passing device 15.
When the ball is stored on the side of 15a, the first rod 25 locks the lower prize ball and the second rod 26 locks the upper prize ball. The spillage from the entrance 15a is positively prevented.

In this state, the ball stopper plate 36 of the ball receiving member 33 is
As soon as the ball passing tool 15 is released, the urging means 39 is used to instantly tilt and return in the counterclockwise direction in the drawing to maintain the standing state. As a result, when the prize ball in the ball exit 14 spills forward from the exit 14b, it is blocked by the ball stop plate 36 to prevent it from jumping forward, and the prize ball contacts the inner surface of the upper part of the ball stop plate 36. In this case, the ball is bounced back inward, received in the passage 34 of the ball receiving member 33, and thereafter discharged to the lower ball receiving tray 17 side.

Further, as a state immediately after the support plate 4 is opened, the state of the apparatus of this example in the case where the ball passing tool 15 is retracted to the ball outlet 14 at the facing position of, for example, one ball, see FIG. As a result, in the elevating / lowering regulating member 21, the third regulating rod 21
As 30 moves away from the guide surface 32 of the displacement guide piece 31 and returns to the upper tilt, the first and second restricting rods 25.26 are displaced upward as shown in the figure, and the lower stage of the ball passage tool 15 is moved. The prize balls and the upper prize balls start to be locked respectively, and spillage from the entrance 15a is restricted.

In addition, in this state, the ball stopper plate 36, the ball insertion tool 15
Is released and returned, and is held in an inclined state in which the upper end thereof is extended to the lower part of the entrance 15a of the ball passage tool 15 as shown in FIG. Regarding the prize balls in the ball exit 14,
As shown in the figure, spilling is prevented while the first and second regulating rods 25.26 are in contact with each other.

As the prize ball outflow restricting device which is the subject of the present invention, the lifting restricting member 21 is different from the above-mentioned four-bar parallel link mechanism structure in that it is a vertically moving structure as shown in FIG. A pair of vertical support rods 41 arranged on both sides of the tool 15 is vertically supported by vertically supporting a support body 42 in which three control rods 25.26.30 shown in the figure are connected, and a biasing means (not shown) is used. Then, it may be configured such that one side is biased. In any of the forms, the entire member 21 is biased and held downward, and the third regulating rod is held.
As the 30 is displaced along the displacement guide piece 31, the first
The restricting rod 25 may be displaceable to the middle and lower portions of the entrance 15a of the ball passage tool 15, and the second restricting rod 26 may be displaceable to the upper end and the upper portion of the entrance 15a. Of course, the member 21 can be attached to the ball outlet 14 side.

[Effect of device]

As can be understood from the above-described embodiment, according to the prize ball outflow restricting device of the present invention, in the normally closed set state of the support plate for the ball receiving tray, the lifting / lowering restricting member is attached by the displacement guide member on the ball outlet side. The first and second of which are displaced in the direction of force
The control rod of (1) is displaced to each position of the lower stage and the middle stage or the upper stage and the middle stage where the circulation of the prize ball can be allowed within the interval between the ball outlet and the ball passing tool, and one of the control rods is brought into contact with the prize ball. Or, in a state where the prize ball is held in the middle part where it can be contacted, the outflow momentum of the prize ball can be appropriately relaxed and controlled, and thereafter, the prize ball can quickly flow out to the ball tray side, so that the prize ball can be prevented from jumping out of the plate. .

In addition, when the support plate is in the open state, the elevating / lowering restricting member immediately returns and transitions when released from the displacement guide member, so that the first and second restricting rods move to the prize balls in the ball passing tool. Since it is held at each position of the lower step portion and the upper step portion that can be locked, in this state, it is possible to positively prevent falling of the prize ball from the entrance side of the ball passing tool.

Particularly, in the device of the present invention, the first and second restricting rods of the ascending / descending restricting member are arranged in parallel at a flow interval which is appropriately larger than the diameter of the sphere, and both restricting rods can be displaced up and down by the radius of the sphere. Since it can be configured with the contents, the device itself can be manufactured easily and compactly and at low cost.
