Abstract

PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing a fluctuation of a game ball in a flow-down direction (direction of movement) during passing through a passage formation member while securing a freedom in arrangement of the passage formation member.SOLUTION: A passage formation member 30 has a first wall part 35 and a second wall part 36, each formed in a protrusion shape, parallelly arranged with an interval between them in a base part 31. A game ball which flows down between the first wall part 35 and the second wall part 36 changes its flow-down direction by a second bent part 58 of the second wall part 36. Since a projection part 62 pointing toward the second bent part 58 is provided on the first wall part 35 opposing the second wall part 58, the game ball goes toward the second bent part 58 if the ball collides with the projection part 62. Thus the game ball can surely be introduced in a bending direction of the second bent part 58, so that a fluctuation of the game ball in its movement in the flow-down direction can be suppressed. In addition, a lower end part of the second wall part 36 can be made shorter by the projection part 62, contributing to downsizing of the passage formation member 30.

As a result, the engaging protrusion 50 is inserted into the notch 49 formed in the base 31 and the engaging claw 51 is inserted into the engaging hole 48 formed in the left and right restricting portion 45, thereby The passage forming portion 33 can be positioned with respect to the portion 31.

  In the base portion 31, a locking hole 52 extending in the thickness direction of the base portion 31 is formed along the outer surface of the rib 42 in the vicinity of the left / right regulating portion 46 positioned on the center side of the base portion 31. Further, the translucent body 41 is formed with locking holes 53 extending in the thickness direction of the translucent body 41 at a plurality of locations on the translucent body 41 at predetermined intervals in the vertical direction.

  On the other hand, the passage forming portion 33 is provided with a columnar locking protrusion 54 extending rearward from the rear end side of the first wall portion 35. The locking projection 54 inserts the engagement projection 50 into the notch 49 of the base portion 31, and inserts the engagement claw portion 51 into the engagement hole 48 of the left and right restricting portion 45, thereby allowing passage to the base portion 31. When the forming portion 33 is positioned, the protruding portion is provided at a position where the forming portion 33 can be inserted into the locking hole portion 52 formed in the base portion 31. Further, the passage forming portion 33 is provided with a columnar locking projection 55 that extends rearward from a plurality of locations on the rear end side of the second wall portion 36. The locking hole portion 53 has the light transmitting body 41 attached to the base portion 31, and the engaging protrusion 50 is inserted into the notch portion 49 of the base portion 31 and the engaging claw is engaged with the engaging hole portion 48 of the left and right restricting portion. When the passage 51 is positioned with respect to the base 31 by inserting the portion 51, it is formed at a position where it can be inserted into the locking projection 55 projecting from the second wall portion 36.

  Thereby, the translucent body 41 is mounted on the base portion 31, and the engaging protrusion 50 is inserted into the notch 49 formed in the base portion 31, and the engaging hole 48 formed in the left and right restricting portion 45. When the engaging claw portion 51 is inserted into the locking hole portion 52 formed in the base portion 31, the locking protrusion portion 54 protruding from the first wall portion 35 is inserted into the light transmitting body 41. A locking projection 55 protruding from the second wall portion 36 is inserted into the locking hole 53. As a result, the movement of the passage forming portion 33 with respect to the surface direction of the base portion 31 and the translucent body 41 is restricted.

  As shown in FIG. 6, the base portion 31 has a plurality of hole portions 31 c formed at a plurality of locations avoiding the light transmitting member mounting hole 40 and the sensor mounting hole 44. The hole portion 31 c is formed so as to penetrate in the thickness direction of the base portion 31. The hole portion 31c is a portion into which the screw S is inserted from the back side of the base portion 31, and is formed in a bowl shape in accordance with the shape (conical shape) of the head surface of the screw S (head screw). . As a result, the head of the screw S can be prevented from protruding from the back surface of the base portion 31. Further, the base portion 31 has positioning pins 31d protruding at a plurality of locations on the back surface. The positioning pin 31d is a part for positioning with respect to the board surface when the base portion 31 is fixed to the board surface of the game board 20. Since the positioning pins 31d protrude from a plurality of locations and the holes corresponding to the positioning pins 31d are formed on the board surface, the position of the base portion 31 with respect to the game board 20 can be uniquely determined.

  On the other hand, as shown in FIG. 5, the passage forming portion 33 has the fastening wall portions 56 into which the screws S inserted into the hole portions 31 c are inserted and fastened, and the second wall portion is provided at a plurality of positions on the back surface of the second wall portion 36. 36 is formed along the front-rear direction. Thereby, after positioning the channel | path formation part 33 with respect to the base part 31 with which the translucent body 41 was mounted | worn, screw S is inserted from the hole part 31c, and it fastens to the 2nd wall part 36, and thereby the base part The passage forming portion 33 can be fixed to 31.

  Here, the first wall portion 35 is set to have a length in the vertical direction larger than the length of the inner wall portion 34, and the second wall portion 36 has a length in the vertical direction larger than the length of the first wall portion 35 and It is set smaller than the length of the outer side wall portion 32. By setting the first wall part 35 and the second wall part 36 to the lengths as described above, the first wall part 35 and the second wall part 36 are respectively connected to the translucent body mounting part 40 (the translucent body 41). ) Are arranged across 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 At the same time that the passage forming portion 33 is fixed to 31, the transparent body 41 can be easily fixed between the base portion 31 and the passage forming portion 33.

  The first wall portion 35 includes a first bending portion 57 that curves so that the lower end side approaches the inner wall portion 34 side, and the second wall portion 36 has the lower end side approaching the first wall portion 35 side. A second bending portion 58 that bends in a straight line is provided. As for the 1st bending part 57 and the 2nd bending part 58, the curve extension parts 57a and 58a are each extended toward back. The lengths of the curved extending portions 57 a and 58 a extending rearward with respect to the first wall portion 35 and the second wall portion 36 are set to be substantially the same as the thickness of the base portion 31.

  On the other hand, the base portion 31 has lower edge notches 59 and 60 for receiving the curved extending portions 57a and 58a, respectively, at positions corresponding to the first wall portion 35 and the second wall portion 36 on the lower edge of the outer periphery. 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 extending portions 57a and 58a. Further, the vertical direction between the ribs 42 below the right and left restricting portion 46 is connected by the rib connecting portion 61, and the lower edge notch portion 59 is formed in the base portion 31 (inclined portion 31 a) below the rib connecting portion 61. Yes. In addition, since the rib connecting portion 61 is set to have the same length and thickness in the front-rear direction and the same length and thickness as the rib 42, the mechanical strength can be ensured.

  As described above, the notch lengths of the lower edge notch portions 59, 60 from the lower edge of the base portion 31 are set to be short, and the lower edge notch portions 59, 60 are formed in the thin inclined portion 31a. Therefore, the cross-sectional area of the base part 31 can be ensured. As a result, it is possible to prevent the mechanical strength of the base portion 31 from being lowered by the lower edge cutout portions 59 and 60.

  Further, since the lower edge notch 59 is formed in the base part 31 (inclined part 31a) below the rib connecting part 61 (on the extension line), the lower edge notch 59 reduces the reduction in the cross-sectional area of the base 31. It can be supplemented by the connecting portion 61. Thereby, it can prevent that the mechanical strength of the base part 31 falls by the lower edge notch part 59. FIG.

  Further, when a game ball flowing down along the first wall portion 35 and the second wall portion 36 collides with the first bending portion 57 and the second bending portion 58, the first bending portion 57 and the second bending portion 58 are The bent extending portions 57a and 58a move downward and bend downward. However, since the lower edge notches 59 and 60 are set to have a width slightly larger than the thickness of the curved extending portions 57a and 58a, the lower edge notched portions 59 and 60 receive the curved extending portions 57a and 58a, 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 bending portion 57 and the second bending portion 58 due to repeated stress that the game ball collides.

  FIG. 7 is a plan view of the passage forming member 30. As shown in FIG. 7, the passage forming member 30 includes 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. Clearances (passages W2, W3) wider than the size of each minute are formed. In addition, 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 are first viewed in plan view. The first curved portion 57 and the second curved portion 58 formed on the lower end side of the wall portion 35 and the second wall portion 36 are visually recognized. Therefore, the game ball that has entered 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 bending portion 57 and the second bending portion 58. It is guided to the inside of the region PE (left side in FIG. 7).

  8 is a cross-sectional view of the passage forming member 30 taken along the line VIII-VIII in FIG. As shown in FIG. 8, a through gate 39 is provided by disposing a detection sensor 38 between the inner wall portion 34 and the first wall portion 35. The upper end 34a of the inner wall 34 is inclined downward toward the opposite side of the first wall 35, and the upper end 35a of the first wall 35 is inclined downward toward the second wall 36. ing. Further, 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 have the same height. Thereby, it is set so that it is difficult for a game ball to enter the through gate 39. Since the upper end 36a of the second wall portion 36 is set higher than the position of the upper end 35a of the first wall portion 35, the second wall portion 36 comes into contact with the upper end 35a of the first wall portion 35 and fails to enter the through gate 39. The game ball thus easily enters the passage W3 between the first wall portion 35 and the second wall portion 36.

  The inner wall portion 34 and the first wall portion 35 are positions where the both ends of the sensor mounting hole 44 formed in the base portion 31 coincide with each other in a front view and the inner wall portion 34 and the first wall portion 35 face each other. In addition, sensor holding portions 34b and 35b are respectively recessed. 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 34 b and 35 b are set to the same height as the lower end of the sensor mounting hole 44 formed in the base portion 31 and the upper surface of the rib 42.

  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. The right and left restricting portion 46 extends along the side surface of the detection sensor 38, and the other end (sensor body 38 b) of the detection sensor 38 is locked to the claw portion 47. As a result, the detection sensor 38 is fixed to the passage forming member 30. The upper surface of the rib 42 is set to the same height as the lower edge of the sensor mounting hole 44, and the rib 42 extends from the base portion 31 to the rear end side. The front side is supported from below. Thereby, the load resistance against the load (bending load) in the vertical direction of the detection sensor 38 (particularly the sensor main body 38b) can be improved, and the detection sensor 38 can be hardly damaged.

  Next, the holding structure of the detection sensor 38 by the passage forming member 30 will be described with reference to FIG. FIG. 9 is a cross-sectional view of the passage forming member 30 taken along line IX-IX in FIG. As shown in FIG. 9, the left side surface of the detection sensor 38 is opposed to the concave portion 34 b of the inner wall portion 34, the engagement protrusion 50, and the left and right restricting portion 45 of the base portion 31, and the right side surface is the first wall portion 35. It is opposed to the recess 35b, the sensor mounting hole 44 of the base portion 31, and the left and right restricting portion 46. Thereby, the detection sensor 38 is restrained in the left-right direction. The detection sensor 38 is held by the passage forming member 30 when the front-rear direction is restrained by the connecting portion 37 and the claw portion 47.

  Further, in the state where the detection sensor 38 is held by the passage forming member 30, the movement of the engagement claw portion 51 in the left-right direction is restricted by the detection sensor 38, so that the engagement claw portion 51 includes the engagement hole 48 and the notch. Cannot leave part 49. Therefore, even if the passage forming portion 33 on the inner wall portion 34 side is not fixed to the base portion 31 with a screw or the like, unless the detection sensor 38 is removed, the engaging claw portion 51 (the passage forming portion 33 on the inner wall portion 34 side). ) From the base portion 31 can be prevented. As a result, the number of fastening and fixing portions of the passage forming portion 33 with respect to the base portion 31 by screws or the like can be reduced, so that the number of steps required for assembling the passage forming member 30 can be reduced.

  Returning to FIG. The first wall portion 35 is formed with a convex portion 61 projecting toward the second wall portion 36 slightly below the upper end 35a. The convex portion 61 is a portion 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 protruding portion 62 that protrudes toward the second wall portion 36 below the convex portion 61. The protrusion 62 is formed on the outer surface 57 c of the first curved portion 57 formed on the lower end 35 c side of the first wall portion 35.

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

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

  As described above, since the protruding portion 63 is formed in a bulging shape with respect to the second wall portion 36 so as to protrude toward both sides of the first wall portion 35 and the outer wall portion 32, the diameter can be increased. Therefore, the fastening hole portion 56 that can be screwed into the screw S can be formed in the protruding portion 63. Since the protruding 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 protrusion 63 into which the screw S is screwed into the fastening hole 56 is improved, the durability of the protrusion 63 can be improved.

  The second wall portion 36 includes a protruding portion 64 that protrudes toward the first wall portion 35 and is positioned between the horizontal position of the convex portion 61 and the horizontal position of the protruding portion 62. The protruding portion 64 is formed above the inner side surface 58 b of the second curved portion 58 formed on the lower end 36 b side of the second wall portion 36.

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

  The second wall portion 36 has a length such that the lower end 36b is located outside the outer edge of the base portion 31 in a front view, and the lower end 36b is located below the horizontal position of the lower end 35c of the first wall portion 35. Is set. Also, the lower end 36b of the second wall 36 is positioned on the opposite side (right side in FIG. 8) of the bending surface (second bending portion 58) from the left and right positions of the lower end 35c of the first wall 35. Is set to The second wall portion 36 is set such that the horizontal position of the lower end 36 b is positioned above the lower end 32 i of the outer wall portion 32.

  The second wall portion 36 is provided with projecting portions 63, 65, 66, and 67 that protrude from the surface facing the outer wall portion 32 toward the outer wall portion 32 at a predetermined interval. The protrusions 63, 65, 66, and 67 are provided so as to protrude in the front-rear direction of the second wall portion 36. The protrusion 32f formed on the outer wall 32 is positioned below the horizontal position of the protrusion 63 formed on the second wall 36, and the protrusion 65 formed on the second wall 36 is a protrusion. It is located below the horizontal position of 32f. The protrusion 32g formed on the outer wall 32 is positioned below the horizontal position of the protrusion 65 formed on the second wall 36, and the protrusion 66 formed on the second wall 36 is a protrusion. Located below the horizontal position of 32g. The protrusion 32h formed on the outer wall 32 is positioned below the horizontal position of the protrusion 66 formed on the second wall 36, and the protrusion 67 formed on the second wall 36 is a protrusion. It is located below the horizontal position of 32h.

  The protruding portion 67 protrudes from the outer surface 58c of the second bending portion 58, and a fastening hole portion 56 is formed in the front-rear direction. The fastening hole portion 56 is a portion into which a screw S inserted into the lower hole portion 31c of the hole portions 31c (see FIG. 6) arranged vertically is screwed. Since the protruding portion 67 is formed so as to largely protrude from the second wall portion 36 toward the outer wall portion 32 side, a large-diameter fastening hole portion 56 that can be screwed into the screw S can be formed. Since the protruding 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 protruding portion 67 is provided on the outer side surface 58c of the second bending portion 58 that is susceptible to the impact of falling game balls, the second bending portion 58 can be hardly damaged. Moreover, since the rigidity of the protrusion 67 in which the screw S is screwed into the fastening hole 56 is improved, 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 region 20b (see FIG. 2) of the game board 20 will be described. In the normal gaming state, the pachinko machine 1 is left-handed and the player plays a game aiming at the starting port (not shown), and after the special gaming state and the special gaming state are finished, the player strikes the right-hand side. Thus, this is a type of gaming machine that plays a game aiming at the variable winning device 23 and the through gate 39. Specifically, when the player strikes left, the game ball flows down on the left side (left side region 20a) of the game region PE. The game balls launched by left-handed are set so as to hardly win the passage forming member 30 and the variable winning device 23 by the arrangement of the variable display unit 21 (central role) and nails (not shown). .

  Further, when the player hits the right, the game ball flows down to the right side (right side region 20b) of the game region PE. In the special game state, most of the game balls launched by the right strike are 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 of shortening the fluctuation time of the symbol display device 21a (ordinary symbol display device) and extending the opening time of the operating ball entry portion 22 (blade 22a) after the special gaming state is finished (so-called time reduction). )have. Since the operation entrance part 22 serves as a starting port of the symbol display device 21a (special symbol display device), the opening time of the operation entrance part 22 (blade 22a) is extended, so that This is to increase the winning frequency and increase the chances of the special gaming state (big win) lottery. As a result, it is possible to obtain many special game state (big win) lottery opportunities in a short time while suppressing a decrease in game balls as compared to the normal game state. The time reduction of the symbol display device 21a (ordinary symbol display device) is started after the end of the special game state, and the special game state (big win) lottery is in the high probability state (probability changing) or the symbol display device 21a (special symbol display) The variation of the device is continued until a predetermined number of times is reached.

  As described above, since the change (lottery) of the symbol display device 21a (ordinary symbol display device) is triggered by the winning of a game ball in the through gate 39, the symbol display device 21a (ordinary symbol display device). Even during the short period of time, the player continues to make a right turn and plays the game aiming at the through gate 39 (passage forming member 30). At this time, the player expects the game ball passing through the passage forming member 30 to flow down toward the working entrance portion 22. This is because the operating ball entrance 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 working ball entering portion 22, it is conceivable to lengthen the passage of the passage forming member 30 that restricts the movement of the game ball. However, if the passage of the passage forming member 30 is lengthened, the area that the passage forming member 30 occupies the game area PE increases. Since the variable display unit 21 (central role) is arranged at substantially the center of the game area PE, the game area PE on the right side or the left side of the variable display unit 21 is restricted by the space by the variable display unit 21. Therefore, if 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 path forming member 30 is downsized to reduce the area that occupies the game area PE in order to secure the degree of freedom of arrangement of the path forming member 30, the path that restricts the movement of the game ball becomes shorter. The performance of guiding the in a specific direction is reduced. If it does so, the flow-down direction (movement direction) of the game ball which passes the channel | path formation member 30 will become irregular easily. If the flow direction (movement) of the game ball becomes too irregular, it becomes difficult to direct the game ball in the direction intended by the player, and the operability of the pachinko machine 1 is lowered, so that the interest of the game is lowered.

  On the other hand, according to the passage forming member 30, the lower end 35 c of the first wall 35 is set to be located above the game board 20 from the position of the lower end 36 b of the second wall 36. The game ball flowing down along the inner side 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). Further, since the projecting portion 62 protrudes toward the bending surface (inner side surface 58b) on the opposing surface (outer side surface 57c) of the first wall portion 35 facing the bending 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 protrusion 62, the game ball moves toward the bending surface (inner side surface 58b). The game ball headed to the bending surface flows down along the bending surface and is guided in the bending direction of the bending surface. Even if the game ball flowing down between the first wall portion 35 and the second wall portion 36 collides with the projection 62 or does not collide, the game ball can be reliably guided in the bending direction of the bending surface. It is possible to suppress variation in the flow direction (movement direction) of the sphere.

  Further, the second wall portion 36 is set such that the lower end 36b is positioned on the opposite side (right 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. Therefore, compared with 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 is provided. The lower end 36b side can be shortened. Thereby, the size in the front view of the passage forming member 30, that is, the space that occupies the game area PE can be reduced. As a result, it is possible to ensure the degree of freedom of arrangement of the passage forming member 30 on the surface of the game board 20.

  As described above, by reducing the space in which the passage forming member 30 occupies the game area PE, the projecting portion 62 and the bent surface (inner side surface 58b) are secured while ensuring the degree of freedom of arrangement of the passage forming member 30. Therefore, it is possible to suppress variation in the flow direction (moving direction) of the game ball flowing down the passage forming member 30 and to prevent the movement of the game ball from becoming irregular. As a result, the game ball can be easily directed in the direction intended by the player, and the operability of the pachinko machine 1 is improved, so that the interest of the game can be enhanced.

  In order to adjust the flow 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 since the flow direction and movement of the game ball can be adjusted by the path forming member 30, at least the path A nail that is driven into the position of the forming member 30 can be omitted.

  Further, the passage forming member 30 is configured such that the first wall portion 35 and the second wall portion 36 can be attached to the base portion 31, and lower ends 35 c and 36 b are disposed outside the outer edge of the base portion 31 in a front view. The length is set to be located. As a result, the outer edge of the base portion 31 can be positioned inside the lower ends 35c, 36b of the first wall portion 35 and the second wall portion 36 in a front view, so that the space where the base portion 31 occupies the game area PE is obtained. Can be small.

  Further, 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 such that the lower end 36b is positioned on the opposite side (right 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. Therefore, compared with 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 which the lower end 36b side of the 2nd wall part 36 protrudes outside the outer edge of the base part 31 can be made small. As a result, even when a game ball flowing down the game area PE collides near the lower end 36b of the second wall portion 36, the lower end 36b side of the second wall portion 36 that is cantilevered by the base portion 31 collides with the game ball. It can be prevented from being damaged or deformed by the energy.

  Further, since the first wall portion 35 is provided with the through gate 39, the detection sensor 38 for detecting the 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 is formed in a concave shape to hold the detection sensor 38, and the back surface of the sensor holding portion 36b is formed in a convex shape toward the second wall portion 36 and protrudes. The second wall portion 36 is located between the horizontal position of the convex portion 61 and the horizontal position of the protruding portion 62 and protrudes toward the first wall portion 35. Projecting portion 64 is provided.

  Since the back surface of the sensor holding portion 35b is formed as a convex portion 61 on the first wall portion 35 as a convex portion 61 directed toward the second wall portion 36, the sensor holding portion 35b and the convex portion 61 are connected to the front and back sides of the first wall portion 35. The thickness of the first wall portion 35 can be reduced as compared with the case where the first wall portion 35 is provided separately. That is, the sensor holding part 35b and the convex part 61 can be provided on the front and back of the first wall part 35 by bending the thin first wall part 35. As a result, since the thickness of the first wall portion 35 can be reduced, the space occupied by the first wall portion 35 on the base portion 31 (particularly the thickness direction of the first wall portion 35 (the left-right direction in FIG. 8)) can be reduced. . Therefore, the space where the base part 31 occupies the game area PE can be reduced, and the space where the passage forming member 30 occupies the game area PE can be reduced.

  Further, the convex portion 61 is located above the protruding portion 62 of the first wall portion 35, and the protruding portion 64 located between the horizontal position of the protruding portion 61 and the horizontal position of the protruding portion 62 is formed on the second wall portion 36. 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 convex portion 61 of the first wall portion 35. After colliding with the protruding portion 64 of the second wall portion 36 and colliding with the protruding portion 62 of the first wall portion 35, it is guided along the bending surface (inner side surface 58 b) of the second wall portion 26. By causing the game ball to collide with the convex portion 61, the projecting portion 64, and the projecting portion 62 while reciprocating between the first wall portion 35 and the second wall portion 36, the flow-down speed of the game ball can be reduced. This makes it 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 bending surface (inner side surface 58b). it can.

  Further, the convex portion 61 protrudes from the protruding portion 62 toward the second wall portion 36 with respect to the first wall portion 35. Therefore, the game ball that falls vertically downward toward the passage W2 between the first wall portion 35 and the second wall portion 36 does not collide with the convex portion 61 or the second wall portion 36, and directly protrudes 62. Cannot touch. 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 energy of the game ball that collides with the projection 62 and faces the bending surface (inner side surface 58b). Energy can be controlled. Thereby, it can suppress that the flow direction (movement direction) of the game ball which flows down along a bending surface varies.

  In the second wall portion 36, the upper end 35 a of the first wall portion 35 is located below the horizontal position of the upper end 36 a, and the second wall portion 36 protrudes above the horizontal position of the convex portion 61 of the first wall portion 35. The part 63 is located. Thereby, the game ball that collides with the protruding 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 protruding portion 63 of the second wall portion 36. Energy decreases. Moreover, although the protrusion part 63 protrudes on both sides of the 1st wall part 35 and the outer side wall part 32, the protrusion length by the side of the 1st wall part 35 is set to the larger value than the protrusion length by the side of the outer side wall part 32. . Thereby, the protrusion 63 tends to become resistance of the game ball flowing down between the first wall 35 and the second wall 36, and the game flowing down between the first wall 35 and the second wall 36. The energy of the sphere can be reduced. Since the variation in energy of the game ball can be reduced, it is possible to suppress variation in the flow direction (movement direction) of the game ball flowing down along the bending surface (inner side surface 58b).

  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, and then collides with the projecting portion 32 f of the outer wall portion 32. After colliding with the 36 projecting portions 65, it collides with the projecting portion 32 g of the outer wall portion 32. Next, after colliding with the projecting portion 66 of the second wall portion 36, it collides with the projecting portion 32 h of the outer wall portion 32, collides with the projecting portion 67 of the second wall portion 36, and then flows downward substantially vertically.

  A large-diameter protruding portion 67 into which the screw S is screwed into the fastening hole portion 56 protrudes from the outer surface 58 c of the second bending portion 58 and projects from the second wall portion 36 toward the outer wall portion 32. The resistance of the game ball flowing down between the second wall portion 36 and the outer wall portion 32 is likely to occur. The energy of the game ball flowing down between the second wall portion 36 and the outer wall portion 32 can be reduced by the protruding portion 67, so that the game ball can easily flow down along the outer wall portion 32. Since the curvature on the lower end 32i side of the outer wall portion 32 is set to a value smaller than the curvature of the first bending portion 57 and the second bending portion 58 formed in the first wall portion 35 and the second wall portion 36, The game balls along the outer wall portion 32 flow down substantially vertically downward. On the other hand, the game balls along the first bending portion 57 and the second bending portion 58 are guided in the bending direction of the first bending portion 57 and the second bending portion 58, so that the flow-down direction (movement direction) of the game balls is different. 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 projections 64 and 65. Since the thickness of the second wall portion 36 can be increased by the protrusions 64 and 65 at those positions, compared to the case where the locking protrusion is provided at a position where the protrusions 64 and 65 are not formed. The thickness of the locking projection 55 can be increased. Accordingly, the second wall portion 36 can be firmly supported by the translucent body 41 by inserting the engaging projection 55 into the engaging hole portion 53 formed in the translucent body 41.

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

  As shown in FIG. 10, a protruding portion 71 protrudes from the outer surface 57 c of the first curved portion 57 formed on the lower end 35 c side of the first wall portion 35. The protrusion 71 is directed to the second curved portion 58 formed on the lower end 36 b side of the second wall portion 36. The protruding portion 71 is provided inside the inclined portion 31a so as to avoid the inclined portion 31a of the base portion 31, and the fastening hole portion 72 is formed at the center along the front-rear direction (the vertical direction in FIG. 10). The fastening hole 72 is a hole into which the screw S is screwed, and the screw S is inserted into a through hole (not shown) formed through the base portion 31 in the thickness direction (the vertical direction in FIG. 10). It is inserted from the back side of the base part 31 and screwed into the fastening hole part 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 protrusion 71 protrudes from the outer surface 57c of the first bending portion 57, and the fastening hole 72 is formed in the front-rear direction. Since the protruding portion 71 is formed so as to largely protrude from the first wall portion 35 to the second wall portion 36 side, a fastening hole portion 72 having a large diameter enough to allow the screw S to be screwed in can be formed. Since the protruding 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 surface 57c of the first bending portion 57 that is susceptible to the impact of falling game balls, the first bending portion 57 can be hardly damaged. Moreover, since the rigidity of the protrusion 71 into which the screw S is screwed into the fastening hole 72 is improved, the durability of the protrusion 71 can be improved.

  As described above, the present invention has been described based on the embodiments, but the present invention is not limited to the above embodiments, and various modifications can be easily made without departing from the spirit of the present invention. It can be guessed. In addition, the numerical values and shapes given in the above embodiment are merely examples, and other numerical values and shapes can naturally be adopted. For example, it is possible to appropriately set the arrangement of various bonuses in the game area PE, the shape of the base portion 31 of the passage forming members 30 and 70, and the like. In addition, the lengths of the inner wall portion 34, the first wall portion 35, the second wall portion 36, and the outer wall portion 32 and the heights (horizontal positions) of the respective upper ends can be set as appropriate.

  In the above embodiment, the pachinko machine 1 has been described as a representative example of the gaming machine. However, the pachinko machine 1 is not necessarily limited to this, and can be applied to a ball game machine such as a sparrow ball game machine or an arrangement ball machine. is there.

  In the above embodiment, the case where the passage forming members 30 and 70 form the four passages W1 to W4 in the game board 20 has been described. However, the present invention is not necessarily limited to this, and the number of passages may be set as appropriate. Is possible.

  In the above-described embodiment, the case where the passage forming members 30 and 70 are disposed on the right side of the variable display unit 21 (central accessory) has been described. However, the present invention is not limited to this, and the passage forming member may be a variable display unit. Of course, it is possible to arrange it on the left side of 21 (central role). In that case, the layout of each wall part is changed so that it may line up with the outer side wall part 32, the 2nd wall part 36, the 1st wall part 35, and the inner wall part 34 in order from the left when the game board 20 is front-viewed. As a result, the game ball can be guided from the outside to the inside of the game area PE by the passage forming member.

  In the above embodiment, the case where 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 will be described. did. However, the present invention is not necessarily limited to this. By 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 integrally, a single passage forming member is formed. Of course, it is possible to use 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.

  Hereinafter, in addition to the gaming machine of the present invention, the concept of various inventions included in the above embodiment will be described.

  A game machine comprising a game board in which a game area in which a game ball flows down is formed on a board surface, and a central accessory arranged substantially in the center of the game area of the game board, on the right or left side of the central bonus A passage forming member attached to the area, the passage forming member being arranged in parallel with a base portion fixed to the board surface of the game board and spaced apart from each other; A first wall portion and a second wall portion, and the second wall portion has a bent surface on the lower end side that changes the flow direction of the game ball to the left or right side with respect to the vertically downward direction. The first wall portion is set so that the lower end is positioned above the game board from the position of the lower end of the second wall portion, and facing the bending surface on the facing surface facing the bending surface. A projecting portion that protrudes, and the second wall portion is below the first wall portion. Gaming machine 1 the lower end opposite the bending direction of the bending plane than the position of the left and right is characterized in that it is set to be positioned.

  According to the gaming machine 1, a game area where a game ball flows down is formed on the board surface of the game board, and a central role is arranged at the approximate center of the game area of the game board, and a passage is formed on the right side or the left side of the central role. A forming member is attached. The passage forming member has a base portion fixed to the board surface of the game board, and a protruding first wall portion and a second wall portion are juxtaposed with the base portion spaced apart from each other. The game ball flowing down between the first wall portion and the second wall portion is changed to the left side or the right side with respect to the vertical downward direction by the bending surface on the lower end side of the second wall portion.

  Here, in order to adjust the flow 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, but since the flow direction and movement of the game ball can be adjusted by the path forming member, at least the passage formation There is an effect that the nail driven into the position of the member can be omitted.

  In addition, since the lower end of the first wall portion is set to be located above the game board from the position of the lower end of the second wall portion, the game ball flowing down along the bending surface is in the bending direction of the bending surface. Be guided. In addition, since the protrusion is provided on the opposing surface of the first wall facing the bending surface toward the bending surface, the game ball flows down between the first wall and the second wall and the protrusion When it hits, the game ball goes to the bending surface. The game ball headed to the bending surface flows down along the bending surface and is guided in the bending direction of the bending surface. Even if the game ball flowing down between the first wall portion and the second wall portion collides with the projection portion or does not collide, the game ball can be reliably guided in the bending direction of the bending surface. Variations in the direction (moving direction) can be suppressed.

  Moreover, since the 2nd wall part is set so that a lower end may be located in the other side of the bending direction of a bending surface rather than the left and right position of the lower end of a 1st wall part, the left and right position of the lower end of a 1st wall part Compared with the case where a lower end is located in the bending direction side of a bending surface, the lower end side of a 2nd wall part can be shortened. Thereby, the magnitude | size in the front view of a channel | path formation member, ie, the space which occupies a game area | region, can be made small.

  Here, since the central combination is arranged at substantially the center of the game area of the game board, the right or left game area of the central combination is restricted by the central combination. Therefore, there is a restriction on the arrangement of the passage forming member. On the other hand, since the space for the passage forming member to occupy the game area can be reduced as described above, the degree of freedom of the arrangement of the passage forming member on the board surface of the game board can be ensured.

  In addition, if the lower end side of the second wall portion is shortened, the size of the passage forming member in a front view, that is, the half of the space that occupies the game area can be reduced, and the flow direction (movement) of the game ball passing through the passage forming member is reduced. Prone to irregularities. If the flow direction (movement) of the game ball becomes too irregular, it becomes difficult to direct the game ball in the direction intended by the player, and the operability of the game machine is reduced, so that the interest of the game is reduced.

  On the other hand, according to the gaming machine 1, by reducing the space that the passage forming member occupies the game area, the passage forming member is caused to flow down by the protrusion and the bent surface while ensuring the freedom of arrangement of the passage forming member. It is possible to suppress the movement of the game ball from becoming irregularly by suppressing the variation in the flow direction (movement direction) of the game ball. As a result, the game ball can be easily directed in the direction intended by the player, and the operability of the gaming machine is improved, so that the interest of 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 integrally formed with the base portion, and the lower end is positioned outside the outer edge of the base portion in a front view. A gaming machine 2 characterized by:

  According to the gaming machine 2, in addition to the effects achieved by the gaming 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 a gaming area. Can occupy a small space.

  Further, since the first wall portion and the second wall portion are attached to the base portion or integrally formed with the base portion, the lower end side of the second wall portion is cantilevered by the base portion. Since the second wall portion is set so that the lower end is positioned 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 second wall portion is bent 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 located on the side of the surface in the bending direction. Thereby, the length which the lower end side of the 2nd wall part protrudes outside the outer edge of a base part can be made small. As a result, even when a game ball flowing down the game area collides near the lower end of the second wall portion, the lower end side of the second wall portion that is cantilevered by the base portion is damaged by the energy of the colliding game ball. There is an effect of preventing deformation.

  In the gaming machine 1 or 2, the first wall portion has 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 portion, and the sensor holding portion. And a convex portion located on the upper side of the protruding portion, and the second wall portion includes a horizontal position of the protruding portion and a protruding portion of the protruding portion. A gaming machine 3 comprising a projecting portion located between a horizontal position and projecting toward the first wall portion.

  According to the gaming machine 3, the detection sensor for detecting the game ball is held on the opposite side of the second wall portion by the sensor holding portion formed in a concave shape on the first wall portion. Since the back surface of the sensor holding portion is formed in a convex shape on the first wall portion as a convex portion toward the second wall portion side, the sensor holding portion and the convex portion are separately provided on the front and back of the first wall portion and In comparison, the thickness of the first wall can be reduced. As a result, the space in which the first wall portion occupies the base portion can be reduced, and the space in which the base portion occupies the game area can be reduced. Therefore, the space for the passage forming member to occupy the game area can be reduced.

  In addition, the convex portion is positioned above the protruding portion of the first wall portion, and a protruding portion located between the horizontal position of the protruding portion and the horizontal position of the protruding portion is provided on the second wall portion. Since the protruding portion protrudes toward the first wall portion, the game ball flowing down between the first wall portion and the second wall portion collides with the convex portion of the first wall portion, and then the second wall portion. After colliding with the protrusion and colliding with the protrusion of the first wall, it is guided along the bending surface of the second wall. By reciprocating between the first wall portion and the second wall portion while causing the game ball to collide with the convex portion, the projecting portion, and the protruding portion, the flow velocity of the game ball can be reduced. As a result, in addition to the effect achieved by the gaming machine 1 or 2, there is an effect that it is possible to reduce both the space of the passage forming member that occupies the game area and the speed of the game ball passing through the bending surface.

  In the gaming 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 away from the base portion, and the base portion is A through hole formed in the thickness direction at a position corresponding to the protruding portion is provided, and the first wall portion includes a hole portion formed in the protruding portion, and is inserted into the hole portion and the through hole. A gaming machine 4 comprising a shaft-like member.

  According to the gaming machine 4, the through hole is formed in 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-like member into the hole and the through-hole, the first wall portion and the second wall portion that are connected to each other at a position apart from the base portion are attached to the base portion. . By inserting the shaft-like member into the protruding portion of the first wall portion, the first wall portion can be firmly fixed to the base portion. In addition, since the shaft-like member is inserted into the protrusion portion of the first wall portion, the rigidity of the protrusion portion can be improved, and in addition to the effect exerted by the gaming machine 2 or 3, the effect of improving the durability of the protrusion portion There is.
