It is set smaller than the length of the outer wall portion 32 . By setting the lengths of the first wall portion 35 and the second wall portion 36 as described above, the first wall portion 35 and the second wall portion 36 are respectively attached to the transparent body mounting portion 40 (the transparent body 41). ) in the vertical direction. As a result, after positioning the passage forming portion 33 with respect to the base portion 31 to which the translucent body 41 is mounted, the screw S is inserted from the hole portion 31c and fastened to the second wall portion 36, whereby the base portion The transparent body 41 can be easily fixed between the base portion 31 and the passage forming portion 33 at the same time as the passage forming portion 33 is fixed to the base portion 31 .

The first wall portion 35 has a first curved portion 57 that curves so that the lower end side approaches toward the inner wall portion 34 side, and the second wall portion 36 has a lower end side that approaches the first wall portion 35 side. It has a second curved portion 58 that curves upward. The first curved portion 57 and the second curved portion 58 have curved extension portions 57a and 58a extending rearward, respectively. The lengths of the curved extending portions 57 a and 58 a extending rearward from the first wall portion 35 and the second wall portion 36 are set substantially equal to the thickness of the base portion 31 .

On the other hand, the base portion 31 has lower edge cutout portions 59 and 60 formed at positions corresponding to the first wall portion 35 and the second wall portion 36 on the lower edge of the outer circumference to receive the curved extension portions 57a and 58a, respectively. ing. The lower edge notches 59 and 60 are formed in the inclined portion 31a of the base portion 31, and the width is set slightly larger than the thickness of the curved extension portions 57a and 58a. Further, the vertical direction between the ribs 42 below the left/right restricting portion 46 is connected by a rib connecting portion 61, and a lower edge notch portion 59 is formed in the base portion 31 (inclined portion 31a) below the rib connecting portion 61. there is The rib connecting portion 61 has the same length and thickness in the front-rear direction as those of the rib 42, so that mechanical strength can be ensured.

As described above, the cutout length of the lower edge cutouts 59 and 60 from the lower edge of the base portion 31 is set short, and the lower edge cutouts 59 and 60 are formed in the thin inclined portion 31a. Therefore, the cross-sectional area of the base portion 31 can be secured. As a result, it is possible to prevent the mechanical strength of the base portion 31 from deteriorating due to the lower edge cutouts 59 and 60 .

In addition, since the lower edge cutout portion 59 is formed in the base portion 31 (inclined portion 31a) below (on the extension line) of the rib connection portion 61, the reduction in the cross-sectional area of the base portion 31 due to the lower edge cutout portion 59 can be prevented. It can be supplemented by the connecting part 61 . Thereby, it is possible to prevent the mechanical strength of the base portion 31 from being lowered by the lower edge notch portion 59 .

Further, when the game ball flowing down along the first wall portion 35 and the second wall portion 36 collides with the first curved portion 57 and the second curved portion 58, the first curved portion 57 and the second curved portion 58 It bends downward, and the curved extension portions 57a and 58a move downward. However, since the width of the lower edge cutouts 59 and 60 is set slightly larger than the thickness of the curved extensions 57a and 58a, the curved extensions 57a and 58a are received by the lower edge cutouts 59 and 60. Deformation (deflection) of the first bending portion 57 and the second bending portion 58 is suppressed. As a result, it is possible to prevent fatigue failure from occurring in the first curved portion 57 and the second curved portion 58 due to the repeated stress of collision of game balls.

FIG. 7 is a plan view of the passage forming member 30. FIG. As shown in FIG. 7, the passage forming member 30 has one game ball between the inner wall portion 34 and the first wall portion 35 and between the first wall portion 35 and the second wall portion 36 in plan view. The gaps (passages W2 and W3) wider than the size of a minute are formed respectively. Also, from the gaps (passages W2, W3) formed between the inner wall portion 34 and the first wall portion 35 and between the first wall portion 35 and the second wall portion 36, the first A first curved portion 57 and a second curved portion 58 formed on the lower end sides of the wall portion 35 and the second wall portion 36 are visible. Therefore, the game ball entering between the inner wall portion 34 and the first wall portion 35 and between the first wall portion 35 and the second wall portion 36 is played by the first curved portion 57 and the second curved portion 58. It is guided to the inside of the area PE (left side of FIG. 7).

FIG. 8 is a cross-sectional view of the passage forming member 30 along line VIII-VIII of FIG. As shown in FIG. 8, a through gate 39 is provided by arranging a detection sensor 38 between the inner wall portion 34 and the first wall portion 35 . An upper end 34a of the inner wall portion 34 slopes downward toward the opposite side of the first wall portion 35, and an upper end 35a of the first wall portion 35 slopes downward toward the second wall portion 36 side. ing. Also, the upper end 34a of the inner wall portion 34 and the upper end 35a of the first wall portion 35 are arranged on the game board 20 so as to be at the same height. As a result, game balls are set to be difficult to enter the through gate 39.例文帳に追加Since the upper end 36a of the second wall portion 36 is set at a position higher than the position of the upper end 35a of the first wall portion 35, the upper end 35a of the first wall portion 35 contacts and the ball fails to enter the through gate 39. The game ball thus played can easily enter the passage W3 between the first wall portion 35 and the second wall portion 36.例文帳に追加

The inner wall portion 34 and the first wall portion 35 are positioned to match both ends of the sensor mounting hole 44 formed in the base portion 31 in a front view, and the inner wall portion 34 and the first wall portion 35 face each other. Sensor holding portions 34b and 35b are recessed in the respective portions. The sensor holding portions 34 b and 35 b are portions for holding both ends of the detection sensor 38 inserted into the sensor mounting hole 44 . The lower end surfaces of the sensor holding portions 34b and 35b are set at the same height as the lower ends of the sensor mounting holes 44 formed in the base portion 31 and the upper surfaces of the ribs .

When the detection sensor 38 is inserted into the sensor mounting hole 44 and the sensor holding portions 34b and 35b from the back side of the base portion 31, the opening 38a through which the game ball passes is held by the sensor holding portions 34b and 35b. A right-and-left restricting portion 46 extends along the side surface of the detection sensor 38 , and the other end (sensor main body 38 b ) of the detection sensor 38 is engaged with a claw portion 47 . Thereby, the detection sensor 38 is fixed to the passage forming member 30 . The upper surface of the rib 42 is set at the same height as the lower edge of the sensor mounting hole 44, and the rib 42 extends from the base portion 31 toward the rear end side. front side) is supported from below. As a result, the load resistance of the detection sensor 38 (especially the sensor main body 38b) against the load in the vertical direction (bending load) can be improved, and the detection sensor 38 can be made less likely to be damaged.

Next, referring to FIG. 9, a structure for holding the detection sensor 38 by the passage forming member 30 will be described. 9 is a cross-sectional view of the passage forming member 30 along line IX-IX in FIG. As shown in FIG. 9, the left side of the detection sensor 38 faces the concave portion 34b of the inner wall portion 34, the engaging projection 50 and the left/right restricting portion 45 of the base portion 31, and the right side faces the first wall portion 35. The concave portion 35 b faces the sensor mounting hole 44 and the left/right restricting portion 46 of the base portion 31 . As a result, the detection sensor 38 is constrained in the left-right direction. The detection sensor 38 is held by the passage forming member 30 by being constrained in the front-rear direction by the connecting portion 37 and the claw portion 47 .

Further, when the detection sensor 38 is held by the passage forming member 30 , the movement of the engaging claw portion 51 in the left-right direction is restricted by the detecting sensor 38 , so the engaging claw portion 51 can move toward the engaging hole portion 48 and the notch. Part 49 cannot be separated. Therefore, even if the passage forming portion 33 on the side of the inner wall portion 34 is not fixed to the base portion 31 with a screw or the like, the engaging claw portion 51 (the passage forming portion 33 on the side of the inner wall portion 34) is not removed unless the detection sensor 38 is removed. ) can be prevented from detaching from the base portion 31 . As a result, it is possible to reduce the number of fastening and fixing portions of the passage forming portion 33 to the base portion 31 using screws or the like, so that the man-hours required for assembling the passage forming member 30 can be reduced.

Returning to FIG. 8, description will be made. The first wall portion 35 has a convex portion 61 formed slightly below the upper end 35a and directed toward the second wall portion 36. As shown in FIG. The convex portion 61 is formed in a convex shape on the back side of the sensor holding portion 35b by bending the first wall portion 35 to form the concave sensor holding portion 35b. Further, the first wall portion 35 has a projecting portion 62 projecting toward the second wall portion 36 below the projecting portion 61 . The projecting portion 62 is formed on the outer side surface 57c of the first curved portion 57 formed on the lower end 35c side of the first wall portion 35 .

The first curved portion 57 is a portion for changing the flowing direction of the game ball to the left side (inside the game area PE) with respect to the vertically downward direction. The inner side surface 57b (bent surface) of the first curved portion 57 is a surface for guiding the game ball that has passed through the through gate 39 toward the inside of the game area PE (left side in FIG. 8). The length of the first wall portion 35 is set so that the lower end 35c is located outside the outer edge of the base portion 31 in a front view.

The second wall portion 36 has a projecting portion 63 projecting toward the first wall portion 35 slightly below the upper end 36a. The projecting portion 63 is formed in a bulging shape extending in the front-rear direction of the second wall portion 36 so as to project to both sides of the first wall portion 35 and the outer wall portion 32 . The protruding portion 63 is set so that the protruding length protruding from the second wall portion 36 toward the first wall portion 35 is longer than the protruding length protruding toward the outer wall portion 32 side. A fastening hole portion 56 is formed in the projecting portion 63 along the front-rear direction. The fastening hole portion 56 is a portion into which the screw S inserted into the upper hole portion 31c of the vertically aligned hole portions 31c (see FIG. 6) is screwed.

As described above, since the projecting portion 63 is formed in a bulging shape with respect to the second wall portion 36 so as to project toward both sides of the first wall portion 35 and the outer wall portion 32, the diameter thereof can be increased. Therefore, it is possible to form the fastening hole portion 56 to the extent that the screw S can be screwed into the projecting portion 63 . Since the projecting portion 63 is fastened and fixed to the base portion 31 , the second wall portion 36 can be firmly fixed to the base portion 31 . Moreover, since the rigidity of the projecting portion 63 with the screw S screwed into the fastening hole portion 56 is improved, the durability of the projecting portion 63 can be improved.

The second wall portion 36 has a projecting portion 64 located between the horizontal position of the projecting portion 61 and the horizontal position of the projecting portion 62 and projecting toward the first wall portion 35 . The projecting portion 64 is formed above the inner surface 58b of the second curved portion 58 formed on the lower end 36b side of the second wall portion 36 .

The second curved portion 58 is a portion for changing the flowing direction of the game ball to the left side (inside the game area PE) with respect to the vertically downward direction. The inner side surface 58b (bending surface) of the second curved portion 58 is a surface for guiding the game ball toward the inside of the game area PE (left side in FIG. 8).

The length of the second wall portion 36 is such that the lower end 36b is positioned outside the outer edge of the base portion 31 when viewed from the front, and the lower end 36b is positioned below the horizontal position of the lower end 35c of the first wall portion 35. is set. Further, the second wall portion 36 is arranged such that the lower end 36b is located on the opposite side (right side in FIG. 8) of the bending surface (second curved portion 58) in the bending direction from the left and right positions of the lower end 35c of the first wall portion 35. is set to The second wall portion 36 is set so that the horizontal position of the lower end 36b is located above the lower end 32i of the outer wall portion 32. As shown in FIG.

Projections 63 , 65 , 66 , 67 protrude toward the outer wall portion 32 at predetermined intervals from each other on a surface of the second wall portion 36 facing the outer wall portion 32 . The protruding portions 63 , 65 , 66 , 67 protrude from the second wall portion 36 in the front-rear direction. The projecting portion 32f formed on the outer wall portion 32 is positioned below the horizontal position of the projecting portion 63 formed on the second wall portion 36, and the projecting portion 65 formed on the second wall portion 36 is located above the projecting portion. It is located below the horizontal position of 32f. The projecting portion 32g formed on the outer wall portion 32 is positioned below the horizontal position of the projecting portion 65 formed on the second wall portion 36, and the projecting portion 66 formed on the second wall portion 36 is positioned above the projecting portion. Located below the horizontal position of 32g. The projecting portion 32h formed on the outer wall portion 32 is positioned below the horizontal position of the projecting portion 66 formed on the second wall portion 36, and the projecting portion 67 formed on the second wall portion 36 is located above the projecting portion. It is located below the horizontal position of 32h.

The protruding portion 67 protrudes from the outer side surface 58c of the second curved portion 58, and the fastening hole portion 56 is formed in the front-rear direction. The fastening hole portion 56 is a portion into which the screw S inserted into the lower hole portion 31c of the vertically arranged hole portions 31c (see FIG. 6) is screwed. Since the protruding portion 67 is formed so as to protrude greatly from the second wall portion 36 toward the outer wall portion 32 side, it is possible to form the fastening hole portion 56 having a diameter large enough to allow the screw S to be screwed therein. Since the projecting portion 67 is fastened and fixed to the base portion 31 , the second wall portion 36 can be firmly fixed to the base portion 31 . In particular, since the protrusion 67 is provided on the outer side surface 58c of the second curved portion 58, which is likely to receive the impact of falling game balls, the second curved portion 58 can be made difficult to break. Moreover, since the protrusion 67 with the screw S screwed into the fastening hole 56 has improved rigidity, the durability of the protrusion 67 can be improved.

Next, the pachinko machine 1 in which the passage forming member 30 is attached to the right side area 20b (see FIG. 2) of the game board 20 will be described. In the pachinko machine 1, in the normal game state, the player hits left and aims at a starting hole (not shown) to play the game, and in the special game state and after the special game state ends, the player hits right. This is a type of gaming machine in which a game is played aiming at the variable prize winning device 23 or the through gate 39. Specifically, when the player hits left, the game ball flows down the left side of the game area PE (left area 20a). A game ball hit by a left-handed strike is set so as to hardly win a prize in the passage forming member 30 or the variable prize-winning device 23 due to the arrangement of the variable display unit 21 (central accessory) and nails (not shown). .

Also, when the player hits to the right, the game ball flows down the right side (right side area 20b) of the game area PE. In the special game state, most of the game balls hit by hitting to the right are placed in the variable winning device 23 due to the arrangement of the variable display unit 21 (central accessory), the right decoration 28, the passage forming member 30 and the nail (not shown). is set to win

The pachinko machine 1 has a function (so-called time saving )have. Since the operating ball entering portion 22 is a starting port of the symbol display device 21a (special symbol display device), by extending the opening time of the operating ball entering portion 22 (wings 22a), the operating ball entering portion 22 This is to increase the winning frequency and increase the chances of the special game state (jackpot) lottery. As a result, it is possible to obtain many opportunities for special game state (big hit) lottery in a short time while suppressing the decrease in the number of game balls as compared with the normal game state. The time saving of the symbol display device 21a (normal symbol display device) is started after the end of the special game state, and during the special game state (jackpot) lottery is a high probability state (probability fluctuation) or the symbol display device 21a (special symbol display) device) is continued until a predetermined number of fluctuations are reached.

As explained above, since the variation (lottery) of the symbol display device 21a (normal symbol display device) is started with the game ball winning the through gate 39 as a trigger, the symbol display device 21a (normal symbol display device) is started. , the player continues hitting to the right and aims at the through gate 39 (passage forming member 30) to play the game. At this time, the player expects that the game ball passing through the passage forming member 30 flows down toward the operating ball entering portion 22 . This is because the operating ball entry portion 22 serves as a starting port for the symbol display device 21a (special symbol display device).

Here, in order to guide the game ball passing through the passage forming member 30 to the operating ball entering portion 22, it is conceivable to lengthen the passage of the passage forming member 30 that regulates the movement of the game ball. However, when the passage of the passage forming member 30 is lengthened, the area occupied by the passage forming member 30 in the game area PE increases. Since the variable display unit 21 (central accessory) is arranged substantially in the center of the game area PE, the space of the game area PE on the right or left side of the variable display unit 21 is restricted by the variable display unit 21 . Therefore, when the passage of the passage forming member 30 is lengthened, the arrangement of the passage forming member 30 is restricted.

On the other hand, if the passage forming member 30 is downsized to reduce the area that occupies the game area PE in order to ensure the degree of freedom in the arrangement of the passage forming member 30, the passage that regulates the movement of the game ball will be shortened. The ability to guide in a specific direction is reduced. As a result, the flowing direction (moving direction) of the game ball passing through the passage forming member 30 tends to become irregular. If the flowing direction (movement) of the game ball becomes too irregular, it becomes difficult for the player to direct the game ball in the direction intended by the player, and the operability of the pachinko machine 1 is deteriorated, thereby reducing the interest of the game.

On the other hand, according to the passage forming member 30, since the lower end 35c of the first wall portion 35 is set to be positioned above the game board 20 from the position of the lower end 36b of the second wall portion 36, the curved surface ( The game ball flowing down along the inner surface 58b) of the second curved portion 58 of the second wall portion 36 is guided in the bending direction of the bending surface (left side in FIG. 8). Furthermore, since the protrusion 62 is provided on the facing surface (outer side surface 57c) of the first wall portion 35 facing the bent surface (inner side surface 58b) toward the bent surface (inner side surface 58b), the first wall When the game ball flows down between the portion 35 and the second wall portion 36 and collides with the projecting portion 62, the game ball heads toward the curved surface (inner surface 58b). A game ball directed toward the curved surface flows down along the curved surface and is guided in the bending direction of the curved surface. Even if the game ball flowing down between the first wall part 35 and the second wall part 36 collides with the projection part 62 or does not collide with it, the game ball can be surely guided in the bending direction of the bending surface. It is possible to suppress variation in the flowing direction (moving direction) of the ball.

The second wall portion 36 is set so that the lower end 36b is located on the opposite side (right side in FIG. 8) of the bending surface (inner side surface 58b) in the bending direction from the left and right positions of the lower end 35c of the first wall portion 35. Therefore, compared to the case where the lower end 36b is located on the bending direction side (left side in FIG. 8) of the bending surface (inner side surface 58b) from the left and right positions of the lower end 35c of the first wall portion 35, the second wall portion 36 can be shortened on the lower end 36b side. As a result, the size of the passage forming member 30 in a front view, that is, the space occupying the game area PE can be reduced. As a result, it is possible to secure a degree of freedom in arranging the passage forming member 30 on the board surface of the game board 20 .

As described above, by reducing the space occupied by the passage forming member 30 in the game area PE, the protrusion 62 and the curved surface (the inner side surface 58b) can be arranged while securing the degree of freedom in the arrangement of the passage forming member 30. Therefore, it is possible to suppress variations in the flowing direction (moving direction) of the game ball flowing down the passage forming member 30, and to suppress the movement of the game ball from becoming too irregular. As a result, it becomes easier for the player to direct the game ball in the direction intended by the player, and the operability of the pachinko machine 1 is improved, so that the interest in the game can be enhanced.

In addition, in order to adjust the flowing direction and movement of the game ball, it is necessary to drive a large number of nails into the board surface of the game board 20, but the passage forming member 30 can adjust the flowing direction and movement of the game ball, so at least A nail driven into the position of the forming member 30 can be omitted.

The first wall portion 35 and the second wall portion 36 of the passage forming member 30 are configured to be attachable to the base portion 31, and the lower ends 35c and 36b extend outward from the outer edge of the base portion 31 when viewed from the front. The length is set to fit. As a result, since the outer edge of the base portion 31 can be positioned inside the lower ends 35c and 36b of the first wall portion 35 and the second wall portion 36 in a front view, the space occupied by the base portion 31 in the game area PE can be reduced. can be made smaller.

Also, since the first wall portion 35 and the second wall portion 36 are attached to the base portion 31 , the lower end 36 b side of the second wall portion 36 is cantilevered by the base portion 31 . The second wall portion 36 is set so that the lower end 36b is located on the opposite side (the right side in FIG. 8) of the bending surface (inner side surface 58b) in the bending direction from the left and right positions of the lower end 35c of the first wall portion 35. Therefore, compared to the case where the lower end 36b is located on the bending direction side (left side in FIG. 8) of the bending surface (inner side surface 58b) from the left and right positions of the lower end 35c of the first wall portion 35, the second wall portion 36 The lower end 36b side can be shortened. Thereby, the length by which the lower end 36b side of the second wall portion 36 protrudes outside the outer edge of the base portion 31 can be reduced. As a result, even if the game ball flowing down the game area PE collides with the vicinity of the lower end 36b of the second wall portion 36, the lower end 36b side of the second wall portion 36 cantilevered on the base portion 31 will can be prevented from being damaged or deformed by the energy of

Further, since the first wall portion 35 is provided with a through gate 39 , a detection sensor 38 for detecting a game ball is held between the inner wall portion 34 on the opposite side of the second wall portion 36 . The first wall portion 35 includes a sensor holding portion 35b formed in a concave shape to hold the detection sensor 38, and a rear surface of the sensor holding portion 36b formed in a convex shape toward the second wall portion 36 and protruding. The second wall portion 36 is positioned between the horizontal position of the convex portion 61 and the horizontal position of the projection portion 62 and protrudes toward the first wall portion 35 . It has a protrusion 64 that

Since the rear surface of the sensor holding portion 35 b is formed in a convex shape on the first wall portion 35 as a convex portion 61 directed toward the second wall portion 36 , the sensor holding portion 35 b and the convex portion 61 are formed on the front and back surfaces of the first wall portion 35 . The thickness of the first wall portion 35 can be made thinner as compared with the case where the first wall portion 35 is provided separately. That is, by forming the thin first wall portion 35 in a curved shape, the sensor holding portion 35b and the convex portion 61 can be provided on the front and back sides of the first wall portion 35 . As a result, since the thickness of the first wall portion 35 can be reduced, the space in which the first wall portion 35 occupies the base portion 31 (in particular, the thickness direction of the first wall portion 35 (horizontal direction in FIG. 8)) can be reduced. . Therefore, the space in which the base portion 31 occupies the game area PE can be reduced, and the space in which the passage forming member 30 occupies the game area PE can be reduced.

Further, the projection 61 is positioned above the projection 62 of the first wall 35 , and the projection 64 positioned between the horizontal position of the projection 61 and the horizontal position of the projection 62 is located on the second wall 36 . be provided. Since the projecting portion 64 projects toward the first wall portion 35, the game ball flowing down between the first wall portion 35 and the second wall portion 36 collides with the projecting portion 61 of the first wall portion 35. , collides with the protrusion 64 of the second wall 36 and the protrusion 62 of the first wall 35, and is then guided along the curved surface (inner surface 58b) of the second wall 26. As shown in FIG. By reciprocating the game ball between the first wall portion 35 and the second wall portion 36 and colliding with the convex portion 61, the projecting portion 64, and the projecting portion 62, the flowing speed of the game ball can be reduced. As a result, it is possible to reduce the space of the passage forming member 30 that occupies the game area PE and to control the movement of the game ball by reducing the speed of the game ball passing through the curved surface (inner side surface 58b). can.

Further, the convex portion 61 protrudes toward the second wall portion 36 from the projection portion 62 with respect to the first wall portion 35 . Therefore, the game ball falling vertically downward toward the passage W2 between the first wall portion 35 and the second wall portion 36 directly hits the projection portion 62 without colliding with the projection portion 61 or the second wall portion 36. cannot be contacted. Since the energy of the game ball is reduced by colliding with the convex portion 61 and the second wall portion 36 before contacting the projection 62, the game ball collides with the projection 62 and heads toward the curved surface (inner side surface 58b). You can control your energy. Thereby, it is possible to suppress variation in the flowing direction (moving direction) of the game ball flowing down along the curved surface.

The second wall portion 36 has the upper end 35a of the first wall portion 35 positioned below the horizontal position of the upper end 36a, and the second wall portion 36 protrudes above the horizontal position of the protrusion 61 of the first wall portion 35. A portion 63 is located. As a result, the game ball that collides with the projecting portion 63 of the second wall portion 36 and flows down between the first wall portion 35 and the second wall portion 36 collides with the projecting portion 63 of the second wall portion 36. energy decreases. The projecting portion 63 projects to both sides of the first wall portion 35 and the outer wall portion 32, and the projecting length on the first wall portion 35 side is set to be larger than the projecting length on the outer wall portion 32 side. . As a result, the projecting portion 63 tends to act as a resistance to the game ball flowing down between the first wall portion 35 and the second wall portion 36, and the game ball flowing down between the first wall portion 35 and the second wall portion 36 does not move. It can lower the energy of the sphere. Since variation in the energy of the game ball can be reduced, variation in the flowing direction (moving direction) of the game ball flowing down along the curved surface (inner surface 58b) can be suppressed.

The game ball flowing down between the second wall portion 36 and the outer wall portion 32 collides with the projecting portion 63 of the second wall portion 36, then collides with the projecting portion 32f of the outer wall portion 32, and then hits the second wall portion. After colliding with the projecting portion 65 of 36, it collides with the projecting portion 32g of the outer wall portion 32. As shown in FIG. Then, after colliding with the projecting portion 66 of the second wall portion 36, it collides with the projecting portion 32h of the outer wall portion 32, and after colliding with the projecting portion 67 of the second wall portion 36, flows substantially vertically downward.

A large-diameter protruding portion 67 into which a screw S is screwed into the fastening hole portion 56 protrudes from the outer side surface 58c of the second curved portion 58 and protrudes from the second wall portion 36 toward the outer wall portion 32. , the game ball flowing down between the second wall portion 36 and the outer wall portion 32 tends to be a resistance. The projecting portion 67 reduces the energy of the game ball flowing down between the second wall portion 36 and the outer wall portion 32 , making it easier for the game ball to flow down along the outer wall portion 32 . Since the curvature of the lower end 32i side of the outer wall portion 32 is set to a value smaller than the curvature of the first curved portion 57 and the second curved portion 58 formed in the first wall portion 35 and the second wall portion 36, The game ball along the outer wall portion 32 flows down substantially vertically. On the other hand, since the game ball along the first curved portion 57 and the second curved portion 58 is guided in the bending direction of the first curved portion 57 and the second curved portion 58, the flowing direction (moving direction) of the game ball is separated. can be set to

The locking projections 55 extending rearward from a plurality of locations on the rear end side of the second wall portion 36 are provided at the positions of the projecting portions 64 and 65 . At those positions, the thickness of the second wall portion 36 can be increased by the amount of the projections 64 and 65. Therefore, compared to the case where the locking projections are provided at positions where the projections 64 and 65 are not formed, , the thickness of the locking protrusion 55 can be increased. Accordingly, by inserting the locking protrusion 55 into the locking hole 53 formed in the transparent body 41 , the second wall section 36 can be firmly supported by the transparent body 41 .

Next, referring to FIG. 10, a pachinko machine according to the second embodiment will be described. The pachinko machine according to the second embodiment has the same configuration as that of the first embodiment except that the passage forming member is different. Therefore, the same reference numerals are assigned to the same parts as in the first embodiment, and the following description is omitted. FIG. 10 is a sectional view of the passage forming member 70 of the pachinko machine according to the second embodiment.

As shown in FIG. 10, a projecting portion 71 protrudes from the outer surface 57c of the first curved portion 57 formed on the lower end 35c side of the first wall portion 35 . The projecting portion 71 faces the second curved portion 58 formed on the lower end 36 b side of the second wall portion 36 . The projecting portion 71 is provided inside the inclined portion 31a of the base portion 31 avoiding the inclined portion 31a, and has a fastening hole portion 72 formed in the center along the front-rear direction (perpendicular to the paper surface of FIG. 10). The fastening hole portion 72 is a hole portion into which a screw S is screwed. It is inserted from the back side of the base portion 31 and screwed into the fastening hole portion 72 . A through hole (not shown) formed through the base portion 31 is formed inside the inclined portion 31a of the base portion 31 and outside the rib 42 (see FIG. 6).

As described above, the projecting portion 71 protrudes from the outer side surface 57c of the first curved portion 57, and the fastening hole portion 72 is formed in the front-rear direction. Since the projecting portion 71 is formed so as to protrude greatly from the first wall portion 35 toward the second wall portion 36 side, it is possible to form the fastening hole portion 72 having a diameter large enough to allow the screw S to be screwed therein. Since the projecting portion 71 is fastened and fixed to the base portion 31 , the first wall portion 35 can be firmly fixed to the base portion 31 . In particular, since the protrusion 71 is provided on the outer side surface 57c of the first curved portion 57, which is likely to receive the impact of falling game balls, the first curved portion 57 is less likely to be damaged. Moreover, since the rigidity of the protrusion 71 having the screw S screwed into the fastening hole 72 is improved, the durability of the protrusion 71 can be improved.

As a result, the passage forming member can guide the game ball from the outside to the inside of the game area PE.

In the above embodiment, the passage forming members 30 and 70 are assembled by providing the inner wall portion 34, the first wall portion 35 and the second wall portion 36 by attaching the passage forming portion 33 to the base portion 31. did. However, it is not necessarily limited to this, and by integrally forming the base portion 31, the inner wall portion 34, the first wall portion 35, the second wall portion 36, and the outer wall portion 32, the passage forming member can be integrated. It is of course possible to use it as a member. In this case, since the inner wall portion 34, the first wall portion 35 and the second wall portion 36 are connected by the base portion 31 and configured as one member, the connecting portion 37 described in the above embodiment can be omitted.

In addition to the gaming machine of the present invention, concepts of various inventions included in the above-described embodiments are shown below.

A game machine comprising a game board having a game area formed on the board surface in which game balls flow down, and a central accessory arranged substantially in the center of the game area of the game board, wherein a game is played on the right side or the left side of the central accessory. A passage forming member attached to the area is provided, and the passage forming member includes a base portion fixed to the board surface of the game board, and a base portion arranged side by side with a space therebetween so that the game balls flow down therebetween. The second wall is provided with a curved surface on the lower end side that changes the flowing direction of the game ball to the left or right with respect to the vertical downward direction. , the first wall portion is set such that the lower end thereof is located above the lower end of the second wall portion, and the opposite surface facing the bending surface faces the bending surface. The second wall portion is provided with a projecting portion, and the second wall portion is set so that the lower end is located on the opposite side of the bending direction of the bending surface from the left and right positions of the lower end of the first wall portion. A gaming machine 1 characterized by:

According to the gaming machine 1, a game area in which game balls flow down is formed on the board surface of the game board, a central accessory is arranged substantially in the center of the game area of the game board, and a passage is provided on the right or left side of the central accessory. A forming member is attached. The passage forming member has a base portion fixed to the board surface of the game board, and a ridge-like first wall portion and a second wall portion are arranged side by side at a distance from each other on the base portion. A game ball flowing down between the first wall portion and the second wall portion is changed in the flowing direction to the left or right side with respect to the vertically downward direction by the curved surface on the lower end side of the second wall portion.

Here, in order to adjust the flowing direction and movement of the game ball, it is necessary to drive a large number of nails into the board surface of the game board. This has the effect of omitting a nail driven into the position of the member.

In addition, since the lower end of the first wall portion is positioned above the game board relative to the position of the lower end of the second wall portion, the game ball flowing down along the curved surface moves in the bending direction of the curved surface. Induced. Furthermore, since the facing surface of the first wall portion facing the bending surface has a projection projecting toward the bending surface, the game ball flows down between the first wall portion and the second wall portion and the projection portion When it collides with , the game ball goes to the curved surface. A game ball directed toward the curved surface flows down along the curved surface and is guided in the bending direction of the curved surface. Even if the game ball flowing down between the first wall part and the second wall part collides with the projection part or does not collide with it, the game ball can surely be guided in the bending direction of the bending surface, so that the game ball flows down. It is possible to suppress variation in the direction (moving direction).

In addition, since the second wall portion is set so that the lower end of the second wall portion is located on the opposite side of the bending direction of the bending surface from the left and right positions of the lower end of the first wall portion, the left and right positions of the lower end of the first wall portion The lower end side of the second wall portion can be shortened compared to the case where the lower end is located on the bending direction side of the bending surface. As a result, the size of the passage forming member in a front view, that is, the space occupying the game area can be reduced.

Here, since the central accessory is placed substantially in the center of the game area of the game board, the game area on the right or left side of the central accessory is restricted in space by the central accessory. Therefore, restrictions arise in the arrangement of the passage forming member. On the other hand, as described above, the space occupied by the passage forming member in the game area can be reduced, so that the degree of freedom in arranging the passage forming member on the board surface of the game board can be ensured.

If the lower end side of the second wall is shortened, the size of the passage forming member in a front view, that is, the space occupying the game area can be reduced, but the downflow direction (movement) of the game ball passing through the passage forming member is reduced. tend to be irregular. If the flowing direction (movement) of the game ball becomes too irregular, it becomes difficult for the player to direct the game ball in the direction intended by the player, and the operability of the game machine deteriorates, thereby reducing the interest in the game.

On the other hand, according to the game machine 1, by reducing the space occupied by the passage forming member in the game area, the passage forming member flows down by the protrusion and the curved surface while securing the degree of freedom in the arrangement of the passage forming member. It is possible to suppress fluctuations in the flowing direction (moving direction) of the game ball to be played, and to suppress the movement of the game ball from becoming too irregular. As a result, it becomes easier for the player to direct the game ball in the direction intended by the player, and the operability of the game machine is improved, so that the interest in the game can be enhanced.

In the gaming machine 1, the first wall portion and the second wall portion are attached to the base portion or formed integrally with the base portion, and the lower ends are positioned outside the outer edge of the base portion in a front view. A gaming machine 2 characterized by:

According to the game machine 2, in addition to the effects of the game machine 1, the outer edge of the base portion can be positioned inside the lower ends of the first wall portion and the second wall portion in a front view, so that the base portion is positioned in the game area. can occupy less space.

Also, since the first wall and the second wall are attached to the base or formed integrally with the base, the lower end of the second wall is cantilevered by the base. The second wall portion is set so that the lower end of the second wall portion is located on the opposite side of the bending direction of the bending surface from the left and right positions of the lower end of the first wall portion. The lower end side of the second wall portion can be shortened compared to the case where the lower end is positioned on the bending direction side of the surface. Thereby, the length by which the lower end side of the second wall protrudes outside the outer edge of the base can be reduced. As a result, even when a game ball flowing down the game area collides with the vicinity of the lower end of the second wall, the energy of the collided game ball damages the lower end side of the second wall that is cantilevered on the base. It has the effect of preventing deformation.

In the game machine 1 or 2, the first wall includes a sensor holding portion formed in a concave shape to hold a detection sensor for detecting the game ball on the opposite side of the second wall, and the sensor holding portion. The rear surface of the second wall portion is formed in a convex shape toward the second wall portion and is located above the projection portion, and the second wall portion is provided with a horizontal position of the projection portion and a position of the projection portion. A game machine 3 characterized by comprising a protruding portion located between the horizontal position and protruding toward the first wall portion.

According to the gaming machine 3, the detection sensor that detects the game ball is held on the opposite side of the second wall by the sensor holding portion that is formed in a concave shape on the first wall. Since the rear surface of the sensor holding portion is formed in a convex shape on the first wall portion as a convex portion directed toward the second wall portion, the sensor holding portion and the convex portion are separately provided on the front and back sides of the first wall portion. By comparison, the thickness of the first wall can be made thinner. As a result, the space occupied by the first wall portion in the base portion can be reduced, and the space occupied by the base portion in the game area can be reduced. Therefore, the space occupied by the passage forming member in the game area can be reduced.

Further, the protrusion is positioned above the protrusion of the first wall, and the second wall is provided with a protrusion positioned between the horizontal position of the protrusion and the horizontal position of the protrusion. Since the protruding part protrudes toward the first wall part, the game ball flowing down between the first wall part and the second wall part collides with the convex part of the first wall part, and then hits the second wall part. After colliding with the protrusion and colliding with the protrusion of the first wall, it is guided along the curved surface of the second wall. By reciprocating the game ball between the first wall portion and the second wall portion while colliding the game ball against the convex portion, the projecting portion, and the projecting portion, the falling speed of the game ball can be reduced. Thereby, in addition to the effect of the game machine 1 or 2, there is an effect of reducing the space of the passage forming member occupying the game area and reducing the speed of the game ball passing through the curved surface.

In the game machine 2 or 3, the first wall portion and the second wall portion are attached to the base portion and connected to each other at a position spaced apart from the base portion, and the base portion A through hole is formed through the thickness direction at a position corresponding to the protrusion, and the first wall portion is provided with a hole formed in the protrusion, and is inserted into the hole and the through hole. A gaming machine 4 characterized by comprising a shaft-shaped member.

According to the game machine 4, a through hole is formed through the thickness direction of the base portion at a position corresponding to the protrusion, and the hole is formed in the protrusion. By inserting (inserting) the shaft-shaped member into the hole and the through hole, the first wall and the second wall, which are connected to each other at a position separated from the base, are attached to the base. . By inserting the shaft-like member into the protrusion of the first wall, the first wall can be firmly fixed to the base. Further, since the shaft-shaped member is inserted into the protrusion of the first wall, the rigidity of the protrusion can be improved, and in addition to the effects of the game machine 2 or 3, the durability of the protrusion can be improved. There is
