As shown in FIGS. 6 to 8, the main body case 52 is formed integrally with the upper end of the inner guide rail 28, and includes a bottom surface portion 52a and a side surface portion 52b standing from one end of the bottom surface portion 52a. have. A space surrounded by the bottom surface portion 52a and the side surface portion 52b serves as a notch portion S. As shown in FIG. The notch S opens the front side facing the transparent plate 11 and the top side facing the boundary region 700 (see FIG. 8). An upper open end of the notch portion S serves as a stopper wall 52c. The stopper wall 52c is formed at the upper end portion of the side surface portion 52b located near the game area 30, and is a columnar wall surface crossing the upper end portion in the width direction.

A bottom surface portion 52a of the body case 52 is formed with a first bearing portion 52d and a guide groove 52e. The guide groove 52e extends in a substantially arc shape along an imaginary circle centered on the first bearing portion 52d. Further, the bottom portion 52a is provided with a first screw hole 52f and a first positioning pin 52g (see FIG. 8). A second positioning pin 52h is provided on the rear side of the bottom surface portion 52a (see FIG. 7). A return prevention mechanism 50 is positioned on the acrylic plate 5a.

The cover 53 is formed in a plate shape and has a second screw hole 53a and a positioning hole 53b. A second bearing portion 53c is formed on the rear side of the cover 53. As shown in FIG. By inserting the first positioning pin 52g of the bottom surface portion 52a into the positioning hole 53b and inserting the screw 55 into the second screw hole 53a and the first screw hole 52f of the bottom surface portion 52a, the cover 53 is attached to the front surface of the notch portion S. It is attached to the main body case 52 with its side closed.

The ball return prevention member 54 has a shaft hole 54a, an on-off valve 54b, and a weight portion 54c. The on-off valve 54b and the weight portion 54c are formed so as to be bent in a doglegged shape bordering on the shaft hole 54a. A support shaft 56 is inserted through the shaft hole 54 a . One end of the support shaft 56 is engaged with the first bearing portion 52 d of the bottom surface portion 52 a and the other end is engaged with the second bearing portion 53 c of the cover 53 . is stopped. Thereby, the ball return preventing member 54 is rotatably supported by the main body case 52 and the cover 53 .

The on-off valve 54b is formed in a substantially rectangular plate shape, and its length in the longitudinal direction (vertical direction) is long enough for the game balls returning from the game area 30 to the boundary area 700 to collide with each other. there is The on-off valve 54b has a first side portion 540b facing the guide passage 29 and a second side portion 541b opposite to the first side portion 540b and facing the game area 30 (left-handed area 30a). (See Figure 9). The first side portion 540b is the portion of the game ball that has been shot from the shooting device 16 and passed through the guide passage 29. As shown in FIG. The second side surface portion 541b is a portion that collides with a game ball trying to return to the guide passage 29 from the game area 30 .

The tip of the on-off valve 54b is tapered. Specifically, the vertical length of the first side surface portion 540b is longer than the vertical length of the second side surface portion 541b. It slopes down towards the tip. A projecting portion 541c projecting toward the game area 30 is formed in the central portion of the second side surface portion 541b.

The weight portion 54c is thicker and heavier than the on-off valve 54b. An engaging pin 54d is projected from the back side of the weight portion 54c, and the engaging pin 54d is inserted into the guide groove 52e of the bottom portion 52a (see FIG. 7). The ball return prevention member 54 is rotatably supported by the main body case 52 and the cover 53 as described above, and is displaceable between the open state and the closed state. In a normal state, the ball return prevention member 54 is urged to rotate in one direction (counterclockwise) around the support shaft 56 by the weight of the weight portion 54c, and the engagement pin 54d moves toward the guide groove 52e. is in contact with one end of the As a result, the ball return prevention member 54 cannot rotate any more and maintains the closed state. On the other hand, the ball return prevention member 54 is rotated in the other direction (clockwise) around the support shaft 56 by the contact force by contacting the game ball shot from the shooting device 16, and is rotated in the other direction (clockwise) as described above. Abutting against the stopper wall 52c results in an open state.

9 and 10, the ball return prevention mechanism 50 when the ball return prevention member 54 is in the closed state (first state) and the ball return prevention member 54 in the open state (second state). The return prevention mechanism 50 will be described. 9 is a front view of the ball return prevention mechanism 50 when the ball return prevention member 54 is in the closed state, and FIG. 10 is a front view of the ball return prevention mechanism 50 when the ball return prevention member 54 is in the open state.

As shown in FIG. 9, when the ball return prevention member 54 is in the closed state (first state), the on-off valve 54b protrudes from the top opening of the notch S toward the outlet of the boundary region 700 in a substantially vertical posture. there is In this state, the distance (specific distance) from the tip portion of the ball return prevention member 54 (open/close valve 54b) to the outer guide rail 27 is shorter than the diameter of the game ball B and the shortest. This distance means the shortest distance from the tip of the on-off valve 54b (first side surface portion 540b) of the ball return prevention member 54 to the outer guide rail 27. As shown in FIG. Therefore, even if the game ball that has once entered the game area 30 collides with the game nail 36 or the like and bounces back toward the boundary area 700 , it collides with the ball return prevention member 54 . Further, the ball return prevention member 54 maintains the closed state even if it collides with the game ball, so it does not rotate counterclockwise. Therefore, the ball return prevention member 54 prevents the game ball that has entered the game area 30 from returning to the guide passage 29 when in the closed state.

In the state shown in FIG. 9, the game ball B shot from the shooting device 16 toward the game area 30 rises through the guide passage 29, enters the boundary area 700, and contacts the on-off valve 54b. The anti-return member 54 can be displaced from the closed state to the open state. Then, as shown in FIG. 10, the ball return prevention member 54 rotates in the direction of opening the exit of the boundary region 700, and when it collides with the stopper wall 52c, further rotation is restricted and the ball is opened. (Second state). In this state, the distance (specific distance) from the tip of the on-off valve 54b (first side surface portion 540b) to the outer guide rail 27 is longer than the diameter of the game ball B and is the longest. Therefore, when the ball return prevention member 54 is in the open state, it allows the game ball shot by the shooting device 16 to enter the game area 30 from the boundary area 700 . After being displaced to the open state, the ball return preventing member 54 is instantly rotated in the opposite direction (counterclockwise) by receiving the biasing force of the weight portion 54c, and is again displaced to the closed state shown in FIG. .

As described above, the ball return prevention mechanism 50 is configured to prevent the game ball that has entered the game area 30 from returning to the guide passage 29 when the ball return prevention member 54 is in the closed state. In this embodiment, it is possible to prevent the game ball from returning to the guide passage (guide area) 29 even in the state (third state) in which the ball return prevention member 54 is being displaced from the closed state to the open state. there is

FIG. 11 shows how a game ball that has entered the game area 30 (left-handed area 30a) is about to return to the boundary area 700 while the ball return preventing member 54 is being displaced from the closed state to the open state. 12 and 13 are enlarged views of the area enclosed by the dashed lines shown in FIG.

In FIG. 12, the point of contact between the other game ball B2 and the tip of the on-off valve 54b is indicated by P4, the point of contact with the outer guide rail 27 is indicated by P5, and the lowest point of the other game ball B2 is indicated by P6. .

In the state shown in FIG. 12, the distance (specific distance) from the tip of the ball return prevention member 54 to the outer guide rail 27 is longer in the open state (see FIG. 10) than in the closed state (see FIG. 9). is shorter than In other words, it is the distance between the closed state and the open state. Moreover, the distance H1 from the tip of the ball return prevention member 54 (open/close valve 54b) to the outer guide rail 27 is shorter than the distance H2 from the lowest point P2 of the other game ball B2 to the outer guide rail 27. In other words, the distance H1 from the point of contact P1 between the other game ball B2 and the tip of the ball return prevention member 54 to the outer guide rail 27 is the distance from the lowest point P2 of the other game ball B2 to the outer guide rail 27. shorter than the distance H2. That is, the length H1 of the perpendicular L1 drawn from the tip of the ball return prevention member 54 to the outer guide rail 27 is the length H2 of the perpendicular L2 drawn from the lowest point P2 of the other game ball B2 to the outer guide rail 27. is shorter than

Further, as shown in FIG. 13, when the ball return prevention member 54 is in the above-described intermediate state, another A distance H3 from the game ball B2 to the contact point P3 of one game ball B1 is shorter than a distance H4 from the lowest point P2 of the other game ball to the contact point P3. That is, the length of the line segment L3 connecting the contact P1 and the contact P3 is shorter than the length of the line segment L4 connecting the lowest point P2 and the contact P3.

Further, as shown in FIGS. 12 and 13, when the ball return prevention member 54 is in the middle state described above, the ball return prevention member 54 reaches the lowest point P2 of the other game ball B2. It doesn't rotate as much. Specifically, the tip of the ball return prevention member 54 is positioned higher than the lowest point P2 of the game ball B2 in the vertical direction, and to the left of the lowest point P2 of the game ball B2 in the horizontal direction (the guide path). 29 side). That is, the tip portion of the ball return prevention member 54 is positioned on the upper left with respect to the lowest point P2.

After the game ball B1 and the game ball B2 collide as described above, even if the game ball B2 tries to return to the guide passage 29, the tip of the ball return prevention member 54 (open/close valve 54b) contacts from the game area 30 side. will do. Therefore, the ball return preventing member 54 is more likely to be rotated counterclockwise by being given a contact force directed from the game area 30 side toward the guide passage 29 side. Therefore, the ball return prevention member 54 closes the exit of the boundary area 700 more than when the game ball B1 and the game ball B2 collide, and it becomes difficult for the game ball B2 to return to the guide passage 29.例文帳に追加As a result, even when the game ball B1 and the game ball B2 collide as shown in FIG. 11, it is possible to prevent the game ball B2 from returning to the guide passage 29. In other words, it is possible to prevent two game balls from returning to the guide passage 29 in succession.

In addition, at the time of collision between the game ball B1 and the game ball B2 as shown in FIG. If the distance H2 from the lowest point P2 of the game ball B2 to the outer guide rail 27 is longer than the distance H2, the game ball B2 will move between the tip of the ball return prevention member 54 and the outer guide rail 27 after the collision. It becomes possible to enter between Then, the game ball B2 can contact the tip of the ball return prevention member 54 from above, so that the ball return prevention member 54 is more likely to rotate clockwise. Therefore, the ball return prevention member 54 opens the exit of the boundary area 700 more than when the game ball B1 and the game ball B2 collide, and the return of the game ball B2 to the guide passage 29 cannot be suppressed.

As described above, the pachinko machine P according to the present embodiment is sufficiently improved to prevent game balls that have entered the game area 30 from returning to the guide path (guide area) 29 compared to conventional pachinko machines. However, as described below, the return prevention is further improved by preventing the ball return prevention mechanism 50 from being caught by the game ball. Therefore, with reference to FIG. 14, prevention of catching between the ball return prevention mechanism 50 and the game ball will be described. FIG. 14 shows a state in which the game ball B returning from the game area 30 to the boundary area 700 collides with the ball return prevention member 54. As shown in FIG.

As shown in FIG. 14 , the game ball B returns from the game area 30 to the boundary area 700 and contacts the opening/closing valve 54 b of the ball return prevention member 54 and the main body case 52 . Specifically, the game ball B is in contact with the projecting portion 541c of the open/close valve 54b in the closed state, and is in contact with the upper end portion of the main body case 52 (stopper wall 52c). In FIG. 14, the point of contact between the game ball B and the projecting portion 541c of the on-off valve 54b is indicated by P7, the point of contact with the upper end of the main body case 52 is indicated by P8, and the leftmost point of the game ball B is indicated by P9. .

In such a state, the point of contact P7 between the game ball B and the projecting portion 541c of the on-off valve 54b is located below the leftmost point P9 of the game ball B in the vertical direction. Further, the point of contact P8 between the game ball B and the upper end of the main body case 52 is positioned to the left of the lowest point P6 of the game ball B in the horizontal direction, and the lowest point P6 of the game ball B in the vertical direction. is also located above. That is, the contact point P8 is located on the upper left with respect to the lowest point P6. The distance (first distance) H5 from the contact point P7 to the contact point P8 is shorter than the distance (second distance) H6 from the leftmost point P9 of the game ball B to the lowest point P6. Therefore, the game ball B is distributed between the opening on the upper surface side facing the boundary area 700 in the main body case 52 (see FIG. 8) and the portion closer to the base end than the projecting portion 541c of the second side surface portion 541b of the on-off valve 54b. , so as not to enter the gap region SP between. Moreover, as indicated by the dotted line arrow in FIG. 14, when the game ball B collides with the ball return prevention member 54, a force is applied to the right from the projecting portion 541c of the on-off valve 54b, and the upper end portion of the main body case 52 It rebounds to the game area 30 by applying force diagonally upward to the right. Therefore, it is possible to prevent the game ball B from being caught between the opening/closing valve 54b of the ball return prevention mechanism 50 and the main body case 52 by entering the gap area SP. Therefore, the return prevention of the ball return prevention mechanism 50 caused by such a game ball B being caught is not impaired. Therefore, since the return prevention of the ball return prevention mechanism 50 can be stably ensured, the return prevention of the game ball entering the game area 30 to the guide passage (guide area) 29 can be further improved.

According to the pachinko machine P according to this embodiment configured in this manner, the following effects can be obtained.

The ball return prevention mechanism 50 not only prevents the game ball that has entered the game area 30 from returning when the ball return prevention member 54 is in the closed state, but also prevents the ball return prevention member 54 from being displaced from the closed state to the open state. It is possible to prevent the game ball entering the game area 30 from returning to the guide passage 29 even while playing. Therefore, it is possible to improve the prevention of the game ball that has entered the game area 30 from returning to the guide passage (guide area) 29 .

In addition, the pachinko machine P according to the present embodiment guides the launched game ball to the game area 30, which is an area between the outer guide rail (outer rail) 27 and the inner guide rail (inner rail) 28. A guide path (guide area) 29 and a ball return prevention mechanism 50 that prevents the game ball from returning to the guide path 29 from the game area 30, and the ball return prevention mechanism 50 is in a closed state (first state). , an open state (second state), an on-off valve (displacement member) 54b that can be displaced, and a main body case (holding member) 52 that can hold the on-off valve 54b. 30, and a tip portion on the tip side of the second side face portion 541b. is a state in which the specific distance is shorter than in the open state, and in the open state is a state in which the specific distance is longer than in the closed state. It has a stopper wall (contacting portion) 52c, and the game ball may contact the stopper wall 52c and the second side surface portion 541b (the protrusion 541c) in the closed state, and the game ball and the stopper wall 52c in the closed state. The distance from the contact point P8 of the game ball and the contact point P7 of the second side surface portion 541b (protruding portion 541c) is the first distance H5, and the distance from the lowest point P6 of the game ball to the leftmost point P9 is the second distance. H6 is characterized in that the first distance H5 is shorter than the second distance H6. Therefore, it is possible to further improve the prevention of the game ball that has entered the game area 30 from returning to the guide passage (guide area) 29 .

Next, with reference to FIGS. 15 and 16, the configuration of the starting port unit (resin member) 60 described above will be described. 15 is a front perspective view showing the starting port unit 60, and FIG. 16 is a rear perspective view showing the starting port unit 60. As shown in FIG.

It has a first out-port forming portion 62b and a second out-port forming portion 62c that form the out port 32 together. The first out port forming portion 62 b is provided on the left side of the starting port forming portion 62 , and the second out port forming portion 62 c is provided on the right side of the starting port forming portion 62 .

A mounting base portion (first resin portion) 69 having a predetermined thickness is formed at each of the four corners on the rear surface of the first plate-like portion 64 . Each attachment base portion 69 is a flat portion that contacts the front surface of the acrylic plate 5a when the first plate-like portion 64 is attached to the acrylic plate 5a. Of these mounting base portions 69, the three mounting base portions 69 formed at the upper right corner, the lower right corner, and the lower left corner on the rear surface of the first plate-shaped portion 64 are provided with screws (fixing members) (FIG. 17). A screw hole (first hole) 67 into which the reference numeral 71) is inserted and a pin (positioning protrusion) 68 that determines the mounting position of the starting port base 61 with respect to the acrylic plate 5a form a pair and are spaced apart by a predetermined distance. are formed adjacent to each other. The screw hole 67 is recessed from the front surface of the first plate-like portion 64 toward the rear surface of the mounting base portion 69 , and penetrates from the front surface of the first plate-like portion 64 toward the rear surface of the mounting base portion 69 . The pin 68 is formed to protrude rearward from the rear surface of the mounting base portion 69 . On the other hand, a mounting base portion (fourth resin portion) 69 formed at the upper left corner of the rear surface of the first plate-like portion 64 has only screw holes 67 and no pins 68 formed therein.

Further, the first plate-like portion 64 has a thin portion (second resin portion) 70 and a thick portion (third resin portion) 75 . The thin portion 70 is a portion formed at the peripheral end portion (in this example, the upper end portion) of the first plate-shaped portion 64 . In this thin portion 70 , the length (dimension) from the front surface to the rear surface of the first plate-shaped portion 64 (that is, the thickness) is smaller than that of the thick portion 75 , and the thickness increases toward the peripheral end of the first plate-shaped portion 64 . It's getting smaller. On the other hand, the thick portion 75 is a portion formed other than the peripheral end portion of the first plate-shaped portion 64 . In this thick portion 75, the length from the front surface to the back surface of the first plate-shaped portion 64 is longer than that of the thin portion 70, and is generally constant.

A second front decoration portion 63 is fixed to the front surface of the second plate-like portion 65 . The second front decoration part 63 has a passage 63 a that cooperates with the second plate-like part 65 to guide the game ball to the general winning opening 33 . The mounting base portion 69 described above is formed at the right end portion of the back surface of the second plate-like portion 65 . Both a screw hole 67 and a pin 68 are formed in the mounting base portion 69 . Further, the second plate-shaped portion 65, like the first plate-shaped portion 64, has a thin-walled portion 70 formed at the peripheral end portion (in this example, the upper end portion) of the second plate-shaped portion 65. , and a thick portion 75 which is a portion formed other than the peripheral end portion of the second plate-shaped portion 65 .

The connecting portion 66 has a first front wall 66a, a second front wall 66b, and a plurality of curved pieces 66c protruding from the back surfaces of these front walls 66a and 66b. The first front wall 66a, the second front wall 66b, and the plurality of curved pieces 66c cooperate with the acrylic plate 5a of the game board 5 to form the plurality of general winning holes 33. A screw hole 67 is formed in a connecting piece 66d that connects the curved piece 66c projecting from the rear surface of the first front wall 66a and the curved piece projecting from the rear surface of the second front wall 66b.

Thus, in the starting port base 61 , a pair of screw holes 67 and pins 68 are formed in each of the three mounting base portions 69 provided on the rear surface of the first plate-shaped portion 64 , and the second plate-shaped portion 65 A set of screw holes 67 and pins 68 are formed in one mounting base portion 69 provided on the rear surface. Also, only a screw hole 67 is formed in one mounting base portion 69 provided on the back surface of the first plate-like portion, and one screw hole 67 is formed in the connecting piece 66d of the connecting portion 66. As shown in FIG.

Next, the attachment of the starting port unit 60 to the game board 5 (acrylic plate 5a) will be described with reference to FIG. FIG. 17 is a perspective view showing attachment of the starting port unit 60 to the acrylic plate 5a. 17, for convenience of explanation, the first front decoration part 64 and the second front decoration part 65 of the starting port unit 60 are not shown.

As shown in FIG. 17, on the front surface of the acrylic plate 5a, there are a plurality of (six in this example) screw through holes (second holes ) 72, and a plurality (four in this example) of pin through holes (positioning holes) 73 into which the pins 68 (see FIGS. 15 and 16) of the starting port base 61 are inserted. When attaching the starting port unit 60 (starting port base 61) to the front surface of the acrylic plate 5a, first, the pins 68 of the starting port base 61 are inserted into the pin through holes 73 of the acrylic plate 5a. At this time, the three pins 68 formed on the first plate-shaped portion 64 of the starting port base 61 and the one pin formed on the second plate-shaped portion 65 are respectively inserted into the pin through holes 73 of the acrylic plate 5a. By inserting, the starting port unit 60 is positioned with respect to the acrylic plate 5a. Next, the screw 71 is screwed into the screw through hole 72 of the acrylic plate 5a through the screw hole 67 of the starting port base 61. As shown in FIG. At this time, four screw holes 67 formed in the first plate-shaped portion 64, one screw hole 67 formed in the second plate-shaped portion 65, and one screw hole 66d formed in the connecting piece 66d of the connecting portion 66 Through the screw hole 67, the screw 71 is screwed into the screw through hole 72 of the acrylic plate 5a. Thereby, the starting port unit 60 can be fixed to the front surface of the acrylic plate 5a.

Next, with reference to FIGS. 18 and 19, the arrangement of the screw holes 67 and the pins 68 of the starting port base 61 will be described. FIG. 18 is an enlarged front view of the vicinity of the starter unit 60 in the game area 30 of the game board 5, and FIG. 19 is an enlarged view of the dotted line frame shown in FIG.

As shown in FIG. 18 , in the second plate-shaped portion 65 , the pin 68 of the mounting base portion 69 is formed in the thick portion 75 and not formed in the thin portion 70 . Specifically, the mounting base portion 69 is formed on the rear surface of the thick portion 75 of the second plate-shaped portion 65 , and the pin 68 of the mounting base portion 69 is also formed on the rear surface of the thick portion 75 . Further, as shown in FIG. 19 , the pin 68 formed at the upper right corner of the rear surface of the first plate-shaped portion 64 is formed in the thick portion 75 and not formed in the thin portion 70 . Specifically, the pin 68 is formed on the rear surface of the thick portion 75 so as to be aligned with the screw hole 67 along the boundary line between the thick portion 75 and the thin portion 70 . A thick portion 75 is formed at the lower left corner and the lower right corner of the rear surface of the first plate-shaped portion 64 , and a pin 68 is formed on the mounting base portion 69 on the rear surface of the thick portion 75 .

Although no pin is formed in the attachment portion (fourth resin portion) at the upper left corner on the back surface of the first plate-like portion 64, if a pin is formed in this position, this pin will be placed in the game area 30. There is a risk of damage due to a relatively large impact from the game ball that has flowed down. Therefore, in order to prevent such a situation in advance, the pin is not formed at this position.

Next, details of the diameter of the screw through hole 72, the diameter of the pin through hole 73, and the length (dimension) of the pin 68 formed in the starting port base 61 will be described with reference to FIG. 20 is a cross-sectional view taken along the line XX-XX of FIG. 18. FIG. In addition, in FIG. 20, hatching is not given for convenience of explanation.

As shown in FIG. 20, the diameter R1 of the pin through-hole 73 is substantially equal to the diameter R2 of the screw through-hole 72 (R1≈R2). Further, the diameter R3 of the pin 68 is smaller than the thickness T1 of the second plate-shaped portion 65 of the starting port base 61 (R3<T1), specifically, the diameter R3 of the pin 68 is 70% or less of D1. is preferred (R3≤0.7D1). Here, the thickness T1 of the second plate-like portion 65 is the length (dimension) from the front surface of the second plate-like portion 65 to the back surface of the mounting base portion 69 in the range where the pin 68 is formed. Furthermore, the length D1 of the portion where the pin 68 is inserted into the pin through hole 73 is smaller than the length D2 of the portion where the screw 71 is inserted into the screw through hole 72 (D1<D2).

The game board 5 according to the present embodiment configured as described above can provide the following effects.

Since the diameter R3 of the pin 68 of the starting port base 61 is smaller than the thickness T1 of the second plate-shaped portion 65, the starting port base 61, which is formed by injection molding a resin material, is less susceptible to sink marks. . Therefore, it is possible to suppress defects in the starting port base 61 .

Further, the length D1 of the portion where the pin 68 is inserted into the pin through hole 73 is smaller than the length D2 of the portion where the screw 71 is inserted into the screw through hole 72. Even if an unexpected external force is applied to the pin, the possibility of the pin breaking and being damaged can be reduced. Therefore, it is possible to suppress defects in the starting port base 61 .

Further, since the diameter R2 of the pin through-hole 73 of the starting port base 61 is substantially equal to the diameter R1 of the screw through-hole 72, these through-holes 72 and 73 can be collectively formed in the manufacturing stage of the acrylic plate 5a. , the work efficiency can be improved and the work cost can be reduced.

Next, a modified example of the pachinko machine P will be described.

(Modification)
A game board 500 according to a modification will be described with reference to FIGS. 21 and 22. FIG. 21 is an enlarged front view of the starting port base 61 attached to the game board 500, and FIG. 22 is a cross-sectional view taken along line XXII-XXII of FIG. In addition, in FIG. 22, hatching is not given for convenience of explanation. The game board 500 differs from the first embodiment in the position of the pin 68 and the size of the pin through-hole 73 of the acrylic plate 5a in the second plate-shaped portion 65 of the starting port base 61 .

As shown in FIG. 21, in the second plate-like portion 65, the positions of the screw holes 67 and the pins 68 of the mounting base portion 69 are different. Specifically, the mounting base portion 69 is formed on the right end portion of the rear surface of the second plate-shaped portion 65 so as to straddle the thin portion 70 and the thick portion 75 . The screw hole 67 of the mounting base portion 69 is formed in the thick portion 75 , while the pin 68 is formed in the thin portion 70 . Although not shown in the drawings, a mounting base portion 69 on the upper right portion of the rear surface of the first plate-shaped portion 64 is formed so as to straddle the thin portion 70 and the thick portion 75. The holes 67 are formed in the thick portion 75 while the pins 68 are formed in the thin portion 70 . The pin 68 may be formed at least in the thin portion 70 , and may be formed so as to straddle the thin portion 70 and the thick portion 75 , for example. Also, when a plurality of pins 68 are formed, some of the pins 68 may be formed in the thin portion 70 and the remaining pins 68 may be formed in the thick portion 75 .

As shown in FIG. 22, the diameter R1 of the pin through hole 73 is larger than the diameter R2 of the screw through hole 72 (R1>R2) and larger than the diameter R4 of the shaft portion 71a of the screw 71 (R1>R4). ), smaller than the diameter R5 of the head 71b of the screw 71 (R1<R5).

FIG. 23 is a sectional view showing the positional relationship between the starting port base 61 attached to the acrylic plate 5a of the game board 5 and the transparent plate 11 held by the front frame 3. As shown in FIG. In addition, in FIG. 23, hatching is not given for convenience of explanation.

As shown in FIG. 23, when the front frame 3 is closed with respect to the inner frame 2 (see FIG. 2), the game board 5 and the transparent plate 11 face each other. In this state, the length (shortest length (dimension)) D3 between the front end of the starting port base 61 and the transparent plate 11 is greater than the length D1 of the portion where the pin 68 is inserted into the pin through hole 73. is also small (D3<D1). Specifically, the front end of the starting port base 61 is the front surface of the first front wall 66a and the second front wall 66b of the connecting portion 66, and the distance between these front surfaces and the rear surface of the transparent plate 11 is D3. is smaller than the length D1 described above.

According to the game board 500 according to the modified example configured in this manner, the following effects can be obtained.

The diameter R3 of the pin 68 of the starting port base 61 is larger than the diameter of the screw through hole 72 and larger than the diameter of the shaft portion 71a of the screw 71, so that the strength of the pin 68 can be improved. 68 becomes difficult to be damaged.

In addition, since the diameter R1 of the pin through-hole 73 is larger than the diameter R2 of the screw through-hole 72 and larger than the diameter R4 of the shaft portion 71a of the screw 71, the pin 68 inserted into the pin through-hole 73 does not move. A predetermined gap can be formed between the outer peripheral surface and the inner peripheral surface of the pin through hole 73, and the pin 68 is less likely to be damaged during insertion. Further, since the diameter R1 of the pin through hole 73 is smaller than the diameter R5 of the head 71b of the screw 71, the durability of the acrylic plate 5a can be maintained. In particular, since the screw through-hole 72 and the pin through-hole 73 are often formed at positions close to each other, the durability of the area of the acrylic plate 5a where these through-holes 72 and 73 are formed tends to be reduced. . Therefore, this design is extremely effective because the durability of the acrylic plate 5a can be maintained.

Further, since the diameter R3 of the pin 68 is smaller than the thickness of the second plate-shaped portion 65 of the starting port base 61, the starting port base 61, which is formed by injection molding a resin material, is less susceptible to sink marks.

Furthermore, since the length D1 of the portion where the pin 68 is inserted into the pin through hole 73 is smaller than the length D2 of the portion where the screw 71 is inserted into the screw through hole 72, the projection amount of the pin 68 is , the pin 68 is less likely to be broken and damaged.

As described above, the starting port base 61 attached to the acrylic plate 5a has various characteristics as described above, so that defects of the starting port base (resin member) 61 can be suppressed.

A pair of screw holes 67 and pins 68 are formed in the mounting base portion 69 of the second plate-shaped portion 65 of the starting port base 61 . while the pin 68 is formed in the thinned portion 70 . Therefore, since the peripheral end portion of the starting port base 61 can be supported and positioned, the positioned starting port base 61 can be sufficiently fixed, and the starting port base 61 can be easily attached to the acrylic plate (board plate) 5a by the screws 71. can do. Further, compared to the starting port base 61 in which the pin 68 is not formed in the thin portion 70 of the peripheral end portion, the size of the starting port base 61 can be reduced by the amount that the pin can be arranged in the thin portion 70 of the peripheral end portion. Therefore, due to this miniaturization, a new space can be formed in the game area 30, and the degree of freedom in designing the game area 30 can be increased.

Furthermore, since the shortest length D3 between the front end of the starting port base 61 and the transparent plate 11 is smaller than the length D1 of the portion where the pin 68 is inserted into the pin through hole 73, By making the width of the direction as small as possible, the game ball can flow down in the game area 30 as designed. On the other hand, the length D1 of the portion where the pin 68 is inserted into the pin through hole 73 is longer than the shortest length D3 between the front end of the starting port base 61 and the transparent plate 11. It is possible to secure a length D1 that is sufficient for positioning, and to suppress defects in the starting port base (resin member) 61 .
