  By the way, as described above, the launch unit disclosed in the cited document 1 has a rotary solenoid disposed on the back side of the mounting base member, and a ball hitting basket and a firing rail disposed on the front side of the mounting base member. Yes. Therefore, when the launch unit is attached to the middle frame, it is necessary to insert the rotary solenoid through an opening formed in the middle frame to avoid interference between the rotary solenoid and the middle frame. For this reason, a rotary solenoid will protrude largely behind the said inner frame. Here, a ball receiving box for collecting the pachinko balls discharged from the pachinko machine is disposed at a position corresponding to the lower position of the pachinko machine on the installation frame base on which the pachinko machine is installed. On the other hand, since the rotary solenoid is disposed below the game board as described above, it is located near the lower part of the pachinko machine. For this reason, in the configuration in which the solenoid protrudes behind the middle frame, there is a problem that the ball receiving box and the solenoid interfere with each other depending on the installation position of the solenoid, and the arrangement position in the middle frame of the launch unit is limited. .

  Then, an object of this invention is to provide the game machine which can install a launch unit in arbitrary positions as needed.

In order to overcome the above-mentioned problems and achieve the intended purpose, a gaming machine according to claim 1 of the present application is
The game board (19) is detachably held on the game board holding part (24) formed on the main body frame (12), and the installation surface part is formed below the game board holding part (24) in the main body frame (12). (25) In a gaming machine in which a launching unit (35) for launching a game ball (S) toward the board surface of the game board (19) is arranged,
The launch unit (35)
Mounting base member (36);
Rotary drive means (37) disposed on the front side of the mounting base member (36);
A launching rail that is disposed on the back side of the mounting base member (36) and is inclined at an angle capable of launching to the board surface of the game board (19), and can stop and hold the game ball (S) at a predetermined hitting ball launch position ( 38)
It is arranged on the back side of the mounting base member (36) and is connected to the rotary shaft (37a) of the rotary drive means (37), and the firing rail (38) is driven by the rotary drive means (37). It consists of a ball ball (42) that launches the game ball (S) stopped and held at the ball launch position toward the board surface of the game board (19),
The installation surface portion (25) is formed with a support portion (26) protruding forward so that the back surface of the launch unit (35) can be attached in a posture facing the installation surface portion (25) ,
The mounting base member (36) extends above the rolling surface (38a) on which the game ball in the firing rail (38) rolls, and the game ball (42) is launched by the ball (42). A fall prevention part (43) that prevents the firing rail (38) of S) from falling forward is formed,
When the launch unit (35) is attached to the support portion (26), the launch rail (38) and the ball hitting basket (42) are positioned between the installation surface portion (25) and the attachment base member (36). In addition, the gist is that the launch rail (38) is configured to be close to the installation surface portion (25) with a spacing smaller than the diameter dimension of the game ball (S) .

As described above, the rotary drive means is arranged on the front side of the mounting base member of the launching unit that launches the game ball toward the game area of the game board, and the back side of the mounting base member is arranged on the rotary shaft of the rotary drive means. In addition to fixing the striking ball provided on the mounting base member, the launching rail is disposed on the back side of the mounting base member, so that the launching unit can be attached to the support portion of the installation surface portion without projecting the rotary drive means to the rear of the main body frame. Can be attached. Accordingly, it is possible to prevent interference between the equipment provided on the installation frame base on which the gaming machine is installed and the rotary drive means, so that the launch unit can be installed at an arbitrary position as necessary. In addition, since it is not necessary to open an opening through which the rotary drive means is inserted in the main body frame, foreign matter can be reliably prevented from being inserted at the installation position of the firing unit.
Further, by providing the mounting base member with a fall prevention portion that extends to above the rolling surface on which the game ball rolls on the firing rail, it is possible to prevent the game ball from falling to the front of the firing rail. . That is, all the game balls sent to the hitting position of the launch rail can be used for the game without being wasted. Similarly, even if the game ball is launched from the launch rail and returned to the launch rail again, the fall prevention unit can prevent the fall of the game ball to the front of the launch rail, so the game ball is wasted. It can be surely used in the game without any problems.

In the gaming machine according to claim 2, a ball feed notch (36c) is formed in the mounting base member (36) so as to extend along the upper end portion of the firing rail (38). The gist is that the game ball (S) from 13b) is sent to the hitting ball launch position of the launch rail (38) via the notch portion (36c) for ball feeding .

In this way, by forming the ball feed cutout portion on the mounting base member so as to extend along the upper end portion of the launch rail, the game ball delivered from the ball feed device can be reliably received via the ball feed cutout portion. Can be sent to the hitting position.

In the gaming machine according to claim 3, the fall prevention portion (43) is formed by extending an edge portion along the upper end portion of the firing rail (38) in the mounting base member (36) upward, The projecting dimension from the rolling surface (38a) of the launch rail (38) in the fall prevention part (43) is 2/3 or more of the diameter dimension of the game ball (S), and the diameter dimension of the game ball (S) The gist is that the following ranges are set .

Thus, by setting the projecting dimension from the rolling surface of the launch rail in the fall prevention portion to a range that is 2/3 or more of the diameter dimension of the game ball and less than the diameter dimension of the game ball, Can be reliably prevented, and an increase in cost and an increase in the size of the launch unit due to an unnecessarily large projecting dimension of the fall prevention unit can be avoided. In addition, since the fall prevention part is integrally formed so as to extend upward from the edge of the mounting base member, it is possible to suppress an increase in cost and eliminate the need for assembling the fall prevention part to the mounting base member. obtain.

The gist of the gaming machine according to claim 4 is that the projecting dimension of the support part (26) from the installation surface part (25) is set to be equal to the width dimension in the front-rear direction of the firing rail (38) .

In this way, by setting the projecting dimension of the support part from the installation surface part to be equal to the width dimension in the front-rear direction of the launch rail, the launch rail comes close to the install surface part when the mounting base member is attached to the support part. Thus, it is possible to reliably prevent the game ball from falling behind the launch rail.

In the gaming machine according to claim 5, a ball tray member (16) for storing a game ball (S) is disposed on the main body frame (12) so as to open and close on the front side of the installation surface portion (25), The gist is that a recess (16a) is formed on the back side of the ball tray member (16) so that the rotary drive means (37) can face when the ball tray member (16) is closed.

Thus, by assembling the ball tray member located on the front side of the launch unit so as to be openable and closable with respect to the main body frame, the assembling work or maintenance work of the launch unit from the front side of the gaming machine (main body frame) can be performed. It can be done easily. Moreover, the recessed part which can face the said rotational drive type means is formed in the back side of the said ball tray member, Therefore The rotational drive means which protrudes ahead can be accommodated reliably.

A speaker 30 is provided. Here, the installation surface portion 25, the ball return passage portion 29, and the front side of the speaker 30 are closed by the plate portion 13 a of the front frame 13 and the ball tray member 16. The handle member 18 is disposed on the right side of the installation surface portion 25 in the middle frame 12.

  As shown in FIG. 2, FIG. 3, FIG. 5, or FIG. 7, a hook-like part 31 protruding forward is formed at the lower end of the game board holding part 24, and the hook-like part 31 is The plate 13 a contacts the frame 13. That is, the installation area of the game board 19 in the middle frame 12 and the installation area of the installation surface portion 25, the ball return passage portion 29, the speaker 30, and the like are configured to be partitioned by the bowl-shaped portion 31. A return port 32 that opens up and down is formed at a position corresponding to the ball return passage portion 29 in the bowl-shaped portion 31, and the game board 19 is formed above the return port 32. The start end opening 22a of the launch passage 22 faces.

  The installation surface portion 25 is formed so as to be positioned on substantially the same plane as the surface of the game board 19 held by the game board holding portion 24 (see FIG. 2 or 3), and a plurality of the launch units 35 are attached. The support portion 26 is formed so as to protrude forward. Here, the projecting dimension of each support section 26 from the installation surface section 25 is set to be substantially the same as the width dimension in the front-rear direction of a launch rail 38 (described later) in the launch unit 35. It is comprised so that it can attach in the attitude | position which made the back surface oppose the installation surface part 25 (refer FIG. 7). That is, when the launch unit 35 is attached to the support portion 26, the installation surface portion 25 can prevent the pachinko ball S on the launch rail 38 from falling backward. In addition, a ball overflow prevention wall 28 protrudes from the installation surface portion 25 at a position facing the upper side of the firing rail 38 in the firing unit 35 attached to the support portion 26, and is spaced upward from the firing rail 38. The pachinko ball S is restricted from moving in the direction.

  Note that screw holes 26a are screwed in a total of four locations with respect to the plurality of support portions 26, and positioning holes 26b are drilled in a total of two locations. Further, as shown in FIG. 3, the wall 27 defining the installation surface portion 25 and the ball return passage portion 29 is provided with the flange-shaped portion 31 positioned on the upper end side of the ball overflow prevention wall 28. In the vicinity, an opening 27a set to an opening size through which one pachinko ball S can pass is opened. It should be noted that a ball discharge passage 12a that discharges the pachinko ball S that has been launched into the game area 19a and used for the game is provided on the back surface side of the installation surface portion 25 (that is, the approximate center position in the left-right direction on the back side of the middle frame 12). The pachinko ball S is discharged to the ball collecting member 51 from the ball discharge passage 12a.

  As shown in FIG. 4 or FIG. 6, the firing unit 35 includes a flat mounting base member 36 attached to the support portion 26, and a rotary solenoid (rotary drive) disposed on the front side of the mounting base member 36. Means) 37, a firing rail 38 disposed on the back surface side of the mounting base member 36, and a hitting ball 42 disposed on the back surface side of the mounting base member 36 and connected to the rotating shaft 37a of the rotary solenoid 37 In preparation. Here, the mounting base member 36 is provided with a through hole 36a penetrating in the front-rear direction at a position corresponding to the screw hole 26a of the support portion 26, and corresponds to the positioning hole 26b of the support portion 26. A positioning protrusion 36b protruding rearward is provided at the position. That is, when the firing unit 35 is fixed to the support portion 26, the mounting base member 36 is positioned in a state in which the positioning protrusions 36b of the mounting base member 36 are inserted into the positioning holes 26b of the corresponding support portion 26 and positioned. The mounting base member 36 is fixed by screwing the screw 46 inserted from the front side of each through hole 36a into the corresponding screw hole 26a. Further, an insertion hole 36d (see FIG. 7) penetrating in the front-rear direction is formed in the lower left position of the mounting base member 36, and the rotation shaft 37a of the rotary solenoid 37 is inserted into the insertion hole 36d. It has become.

  The firing rail 38 is disposed at an upper position on the back side of the mounting base member 36 so as to incline upward in the left direction. Here, the firing rail 38 is attached to the attachment base member 36 so that the inclined upper end faces the opening 27 a of the drawing wall 27 and extends in the tangential direction of the outer rail 20 of the game board 19. That is, the pachinko ball S launched along the launch rail 38 arrives at the outer rail 20 (launch passage 22) via the opening 27a of the painting wall 27 and the return port 32, and the outer rail 20 It moves to the upper position of the game board 19 along (the launch passage 22). As shown in FIG. 7, the launch rail 38 is formed in a substantially M-shaped cross section, and guide grooves 38b are formed along the longitudinal direction of the rolling surface 38a on which the pachinko balls S roll on the launch rail 38. (Refer to FIG. 4 or FIG. 7) is formed, and the pachinko ball S on the firing rail 38 (rolling surface 38a) is configured to move along the guide groove 38b.

  Also, on the back side of the mounting base member 36, as shown in FIG. 6, a ball regulating member 39 that abuts on the pachinko ball S and prevents falling is provided at an upper position on the inclined lower end side of the firing rail 38. The pachinko ball S is stopped and held at the inclined lower end portion of the firing rail 38 by the ball regulating member 39. In the following description, the position where the ball restricting member 39 stops and holds the pachinko ball S is referred to as a hitting ball firing position. An upper stopper 40 for restricting the position of the hitting ball 42 is provided on the back side of the mounting base member 36 at a lower position on the inclined lower end portion side of the firing rail 38, and a rotary solenoid 37 is provided. A lower stopper 41 for restricting the position of the hitting ball 42 is provided on the right side of the position (left side in FIG. 6). The upper and lower stoppers 40 and 41 are formed of an elastic member such as rubber, and buffer the impact caused by the collision of the hitting ball 42.

  As shown in FIG. 6, the hitting ball 42 is a rod-shaped member having a required length, and a rotary shaft 37 a of the rotary solenoid 37 is fixed to one end so as to face between the upper and lower stoppers 40 and 41. In addition, a resilient portion 42a made of a coil spring, rubber material or the like is provided at the other end. That is, the hitting ball 42 is always held in an initial position extending rightward from the rotary shaft 37 a of the rotary solenoid 37 and contacting the lower stopper 41, and the elastic ball 37 is driven as the rotary solenoid 37 is driven. The emitting portion 42a is swung to the final position facing the hitting ball launch position of the launch rail 38. When the hitting ball 42 arrives at the final position, the swinging of the hitting ball 42 is brought into contact with the upper stopper 40 and the swinging is restricted. Thereafter, the hitting ball 42 is returned to its initial position by its own weight. That is, each time the energization of the rotary solenoid 37 is energized, the hitting ball 42 is oscillated and shifted between the initial position and the end position so that the pachinko ball S at the hitting ball launch position on the launch rail 38 can be launched. It has become. The ball feeding device 13b sends the pachinko ball S of the upper ball tray 15 to the launch rail 38 (hit ball launching device) after the hitting ball 42 has arrived at the final position and launched the pachinko ball S. The firing control device (not shown) controls the operation timing of the ball feeding device 13b and the rotary solenoid 37.

  Here, as shown in FIG. 4 or FIG. 6, the mounting base member 36 is formed to extend (project) above the rolling surface 38 a of the firing rail 38. That is, a portion of the mounting base member 36 that extends above the rolling surface 38 a of the firing rail 38 functions as a fall prevention unit 43 that prevents the pachinko ball S from falling on the front side of the firing rail 38. . Here, the protrusion dimension L of the fall prevention part 43 from the rolling surface 38a of the launch rail 38 is set to be in the range of 2/3 ≦ L ≦ diameter dimension of the diameter dimension of the pachinko ball S. That is, if the protrusion dimension L of the fall prevention part 43 is set smaller than 2/3 of the diameter dimension of the pachinko ball S, there is a possibility that the fall of the pachinko ball S cannot be prevented. If the projecting dimension L is set larger than the diameter dimension of the pachinko ball S, the drop prevention part 43 becomes larger than necessary, leading to an increase in cost and a problem that the launch unit 35 becomes larger.

  The mounting base member 36 is notched so that the end side of the firing rail 38 close to the ball hitting position extends along the upper end of the firing rail 38 with respect to the fall prevention portion 43. The ball feeding device 13b is set to face the notch (hereinafter referred to as a ball feeding notch 36c). That is, the pachinko ball S from the ball feeding device 13b is sent to the hitting position of the firing rail 38 via the ball feeding notch 36c. When the front frame 13 is closed, the ball feeding device 13b is in contact with the front surface of the mounting base member 36, and the ball feeding notch 36c is closed. The pachinko ball S sent out to the front is prevented from dropping to the front of the mounting base member 36 via the ball feed notch 36c.

(Effects of Example)
Next, the operation of the pachinko machine 10 according to the embodiment will be described.

  The firing unit 35 has a rotary solenoid 37 screwed to the mounting base member 36 in a state where the rotary shaft 37a is inserted into the insertion hole 36d from the front side of the mounting base member 36, and the rear surface side of the mounting base member 36. In addition, the launch rail 38 is attached at a predetermined inclination angle, the ball restricting member 39 and the upper and lower stoppers 40, 41 are attached, and the rotary shaft 37a of the rotary solenoid 37 is positioned between the upper and lower stoppers 40, 41. It is assembled by attaching the hitting ball 42 to the. Then, with the back surface of the mounting base member 36 facing the installation surface portion 25 of the middle frame 12, the positioning projection 36 b of the mounting base member 36 is inserted into the positioning hole 26 b of the support portion 26 formed in the installation surface portion 25. By inserting, the firing unit 35 is positioned at a predetermined position, and in this state, the screw 46 is screwed into the screw hole 26a of the support portion 26 from the front side of each through hole 36a formed in the mounting base member 36. The firing unit 35 is attached to a predetermined position of the installation surface portion 25 in a posture in which the back surface of the firing unit 35 is opposed. Thus, the firing rail 38 and the hitting ball 42 are located between the installation surface portion 25 and the mounting base member 36.

  In this way, the positioning projection 36b is formed on the mounting base member 36 of the launch unit 35, and the positioning hole 26b is formed in the support portion 26 of the installation surface portion 25, thereby facilitating positioning and fixing of the launch unit 35. Therefore, the assembling work of the firing unit 35 can be easily performed. Further, by attaching the rotary solenoid 37, the firing rail 38, the ball restricting member 39, the upper and lower stoppers 40, 41, and the hitting ball 42 to the mounting base member 36 as a unit, the assembling work of the firing unit 35 is shortened. This can be done in time, and the work efficiency can be improved. Further, since the relative positional relationship between the firing rail 38 and the hitting ball 42 can always be kept constant, when the rotary solenoid 37 is operated to swing the hitting ball 42, the hitting ball 42 There is an advantage that the bullet hitting portion 42a can be surely brought to the hitting ball launch position and the pachinko ball S can be launched accurately.

  Here, when the game board 19 is enlarged and the game board holding part 24 is formed at a position below the middle frame 12 as in recent years, it is necessary to provide the installation surface part 25 on which the firing unit 35 is disposed below. In this case, since the handle member 18 is provided on the right side of the middle frame, it is difficult to move the formation position of the installation surface portion downward with the configuration in which the installation surface portion is formed on the right side of the middle frame. For this reason, it is necessary to move the formation position of the installation surface portion in the middle frame to the left. In this case, considering the launch of the pachinko ball into the launch path of the game board, the substantially central position of the middle frame in the horizontal direction It is optimal to form in. However, since the ball collection member 51 provided on the installation frame base 50 faces a substantially central position in the left-right direction on the back side of the pachinko machine (middle frame), the rotary solenoid is located behind the middle frame as in the conventional case. In the configuration protruding to the center, it is difficult to dispose the launch unit by providing the installation surface portion at a substantially central position in the left-right direction of the pachinko machine (inner frame).

  On the other hand, in the launch unit 35 according to the embodiment, the rotary solenoid 37 is disposed on the front side of the mounting base member 36, and the launch rail 38, the hitting ball 42, etc. are provided on the back side of the mounting base member 36. In addition to providing the support portion 26 on the installation surface portion 25, the rotary solenoid 37 can be disposed on the installation surface portion 25 without protruding rearward of the middle frame 12. Accordingly, since the rotary solenoid 37 does not interfere with the ball collecting member 51 provided on the installation frame base 50 on which the pachinko machine 10 is installed, the installation surface portion 25 on which the launch unit 35 is installed is arranged in the horizontal direction of the middle frame 12. It can be formed at a substantially central position. As described above, by arranging the rotary solenoid 37 on the front side of the mounting base member 36 as in the embodiment, the firing unit 35 can be provided regardless of the formation position of the installation surface portion 25. The degree of freedom in designing a pachinko machine can be improved, such as an increase in size.

  Further, in the configuration in which the rotary solenoid 37 is attached to the back side of the attachment base member 36, the intermediate frame 12 (installation surface portion 25) is prevented from interfering with the rotary solenoid 37 and the intermediate frame 12 (installation surface portion 25). There is a problem in that it is necessary to form an opening, and there is a high possibility that an illegal act such as inserting a foreign object through the opening is performed. On the other hand, in the embodiment, since the rotary solenoid 37 is arranged on the front side of the mounting base member 36, there is no need to open an opening in the middle frame 12 for inserting the rotary solenoid 37. There is an advantage that can be prevented from being inserted.

  Further, by arranging the rotary solenoid 37 on the front side of the mounting base member 36, the firing unit 35 (rotary solenoid 37) protrudes forward as compared with the conventional case. In the embodiment, the concave portion 16a capable of accommodating the rotary solenoid 37 is formed on the back side of the ball dish member 16, so that the rotary solenoid 37 protruding forward can be reliably accommodated. Further, since the ball tray member 16 located on the front side of the launch unit 35 is assembled to the middle frame 12 so as to be openable and closable, maintenance work and the like of the launch unit 35 can be easily performed.

  Furthermore, in the embodiment, since the projecting dimension of the support part 26 formed on the installation surface part 25 is set to be substantially equal to the width dimension in the front-rear direction of the firing rail 38, the attachment base member 36 is attached to the support part 26. In this case, the launch rail 38 comes close to the installation surface portion 25, and the pachinko ball S can be prevented from falling behind the launch rail 38. Further, by providing the mounting base member 36 with the fall prevention portion 43 extending above the upper end edge of the launch rail 38, the fall of the pachinko ball S to the front of the launch rail 38 is prevented. Is possible. Further, since the ball overflow prevention wall 28 that covers the upper portion of the launch rail 38 is formed on the installation surface portion 25, the pachinko ball S is prevented from falling forward of the launch rail 38 beyond the fall prevention portion 43. Can do.

  Here, it is also conceivable that the fall prevention part is a separate member from the firing unit 35 (attachment base member 36), and the fall prevention part as the separate member is provided on the attachment base member 36 or the plate part 13a of the front frame 13. However, in this case, inconveniences such as an increase in cost and complicated assembly work occur. On the other hand, as in the embodiment, the mounting base member 36 extends above the rolling surface 38a of the firing rail 38 to provide the fall prevention portion 43, thereby suppressing an increase in cost. There is an advantage that the work of assembling the fall prevention unit 43 is not necessary. At this time, the projection dimension L of the fall prevention part 43 from the rolling surface 38a of the launch rail 38 is set to be within a range of 2/3 ≦ L ≦ diameter dimension of the diameter dimension of the pachinko ball S, so that the pachinko ball S can be reliably prevented from falling forward, and problems such as an increase in cost due to an increase in the size of the mounting base member 36 and an increase in the size of the launch unit 35 itself can be avoided.

  That is, all the pachinko balls S sent to the hitting position of the launch rail 38 do not deviate from the space surrounded by the installation surface portion 25, the fall prevention portion 43 and the ball overflow prevention wall 28. It can be used for gaming without making it. Further, the pachinko ball S that has been launched by the striking ball 42 and entered the launch passage 22 of the game board 19 may return along the outer rail 20 without being fired into the game area 19a depending on the momentum. . In this case, since the opening size of the opening 27a of the painting wall 27 that defines the installation surface portion 25 and the ball return passage portion 29 is set to a size through which one pachinko ball S can pass, The pachinko ball S is prevented from returning into the installation surface portion 25 (that is, the launch rail 38 side), and is discharged to the lower ball tray 17 through the ball return passage portion 29. Even if the pachinko ball S returns to the launch rail 38 through the opening 27 a of the drawing wall 27, it is surrounded by the installation surface portion 25, the fall prevention portion 43, and the ball overflow prevention wall 28. The game can be reliably used without departing from the space.
