(FIG. 5B). The game ball held in the ball guide port 89 falls to the ball receiving member 77 side when the “ball feed execution state” is entered next, and is supplied onto the firing rail 12 through the ball supply port 75. .

  The striking rod 63 is supported on the back side of the mounting plate 70 so as to be swingable around a swing shaft 93 in the front-rear direction, for example, at an intermediate position in the longitudinal direction. For example, it protrudes in the counterclockwise direction, and is elastically urged in the striking direction (counterclockwise direction) of the flange 94 by the firing spring means 65 on the swing shaft 93, for example. Further, a ball feed driving unit 95 for pushing and swinging the ball feed interlocking means 64 at the time of the swing is fixed to the striking rod 63, for example, at an intermediate portion between the swing shaft 93 and the flange 94.

  The ball feed interlocking means 64 is formed in a substantially L-shape when viewed from the front by the driving arm 96 and the driven arm 97, and at its bent portion, for example, on the lower side of the firing rail mounting plate 71 by a fixed shaft 98 in the front-rear direction. It is pivotably supported. When the striking rod 63 is driven to swing clockwise, the ball feed interlocking means 64 is pivoted counterclockwise by the driven arm 97 being pushed by the ball feed driving unit 95, whereby the drive arm 96 is interlocked. The roller 85 of the member 79 is pushed upward.

  The firing spring means 65 is supported on the front side of the mounting plate 70 so as to be rotatable about the same axis as the swinging shaft 93 of the striking rod 63, and is a substantially circular drive-side spring end member 101 and operation-side spring end arranged in the front-rear direction. A member 102 and a coil spring (not shown) for connecting the spring end members 101 and 102 are provided, and are inserted from the rear side into a mounting hole formed in the front frame 2.

  The drive side spring end member 101 is fixed to the striking rod 63 side via the swing shaft 93, and the operation side spring end member 102 is fixed to the firing handle 10 side within the mounting boss portion 67 via the wire 65a. When the firing handle 10 is rotated in a predetermined direction (clockwise), the operation side spring end member 102 rotates counterclockwise via the wire 65a according to the operation amount, and the drive side spring end member 101 side by the coil spring , That is, the striking force of the striking rod 63 is increased.

  The firing drive motor 66 is detachably mounted on the rear side of the mounting plate 70 with the drive shaft 104 protruding to the front side of the mounting plate 70 through the opening 70a. The firing drive cam 105 is fixed corresponding to the drive receiving portion 103. The firing drive motor 66 continuously rotates the firing drive cam 105 counterclockwise to swing the drive receiving portion 103, that is, the striking rod 63, by a predetermined angle in the clockwise direction against the spring force of the firing spring means 65. It is designed to repeat the action of releasing the force after the release.

  By the driving of the firing drive motor 66, the striking rod 63 that is swung clockwise through the firing drive cam 105, the drive receiving portion 103, the support fitting 103a, and the swing shaft 93 and moved from the initial position to the firing preparation position is When the pressing force of the drive receiving portion 103 by the firing drive cam 105 is released and the spring force of the launch spring means 65 returns to the initial position all at once, the game ball supplied on the launch rail 12 by the ball feed means 13 The part 94 is hit along the launch rail 12 and fired toward the game area 21.

  The attachment boss portion 67 is detachably attached to the front side of the attachment plate 70 and is inserted into the attachment hole formed in the front frame 2 from the rear side. The firing handle 10 is detachably attached to the mounting boss portion 67 from the front side of the front frame 2. The launch handle 10 is provided with a contact detection switch (not shown) that detects the player's grip.

  Further, as shown in FIGS. 6 and 8, the pachinko machine returns the foul ball returned to the launch rail 12 side without returning to the game area 21 despite being launched by the launch means 9. Return ball blocking means 111 is provided. The return ball blocking means 111 is provided in the vicinity of the rear end portion 12b of the firing rail 12 and opens the passage space in the “pass blocking state” that blocks at least a part of the passing space of the game ball at the rear end portion 12b of the firing rail. An opening / closing member 112 that can be changed to a “passable state” and an interlocking means 113 that links the opening / closing member 112 with the driving operation of the firing drive motor 66 on the firing means 9 side are provided.

  As shown in FIG. 9, the opening / closing member 112 has a width in the front-rear direction that is substantially the same as that of the firing rail 12, for example, and the length along the longitudinal direction of the firing rail 12 is formed to be about several game balls. For example, an elastically deformable sliding plate portion 114 and a blocking plate portion 115 extending upward at a substantially right angle from the distal end side of the sliding plate portion 114 are integrally provided, and the blocking plate portion 115 is provided on the firing rail 12. In the “passage blocking state” (FIG. 9), the upper end of the passing space of the game ball is blocked and the support end 114a of the sliding plate 114 opposite to the blocking plate 115 is positioned above the passing space. In a state indicated by a solid line), the support end portion 114a is fixed to the front side of the firing rail mounting plate 71 by the fixing means 117.

  The opening / closing member 112 is provided such that when a game ball collides with the blocking plate 115 from the outer rail 22 side, the center of gravity of the game ball comes closer to the outer rail 22 side than the rear end portion 12b of the launch rail 12. The foul sphere returned from the outer rail 22 side collides with the blocking plate portion 115 of the opening / closing member 112 in the “passage blocking state”, and then all of the foul balls are fired without being placed on the rear end portion 12b of the firing rail 12. It falls into a foul ball guide passage 57 between the rail 12 and the outer rail 22.

  The interlocking means 113 connects the opening / closing operation means 118 provided in the vicinity of the opening / closing member 112, the opening / closing driving means 119 provided on the firing drive motor 66 side, and the opening / closing operation means 118 side and the opening / closing drive means 119 side. And a connecting member 120 made of a wire or the like.

  The opening / closing operation means 118 changes the opening / closing member 112 from the “passage-preventing state” to the “passage-permitted state” by driving on the opening / closing drive means 119 side. An opening / closing operation member 121 that engages with the swing end side, that is, the blocking plate portion 115 side, and an opening / closing support case 122 that supports the opening / closing operation member 121 slidably in the operation direction of the opening / closing member 112, for example, substantially in the vertical direction. For example, a spring member 123 that is disposed in the opening / closing support case 122 and elastically biases the opening / closing operation member 121 substantially downward is fixed to the front side of the extending portion 72 of the firing rail mounting plate 71.

  As shown in FIG. 9, the opening / closing operation member 121 is formed, for example, in the shape of a bowl on the lower side of the guide shaft 121a having a predetermined cross section of a circular shape or other predetermined shape on the lower side, and on the lower end side of the guide shaft 121a. And the engaging portion 121b. One end side of the connecting member 120 is fixed to the upper end side of the opening / closing operation member 121, and the engaging portion 121 b on the lower end side is the swing end side of the opening / closing member 112, for example, the distal end of the blocking plate portion 115 on the opening / closing member 112 side. It is engaged with, for example, a slit-like engaged portion 116a formed on an engaging plate portion 116 that extends from the side toward the other end side of the sliding plate portion 114 at a substantially right angle.

  The engaging portion 121b of the opening / closing operation member 121 has its upper surface side on the lower surface side of the engaging plate portion 116 on the opening / closing member 112 side when the opening / closing operation member 121 is in an inoperative state (a state where it is not pulled by the connecting member 120). When the opening / closing operation member 121 is in an operating state (a state pulled by the connecting member 120), it is engaged with the engaging plate portion 116 and pulled upward. Thus, when the opening / closing operation member 121 is in the non-operating state, the opening / closing member 112 is maintained in the “passage blocking state” (the state indicated by the solid line in FIG. 9). “Passable state” (state indicated by a two-dot chain line in FIG. 9).

  Since the engaged portion 116a of the opening / closing member 112 is slidable along the guide shaft portion 121a on the opening / closing operation member 121 side, the opening / closing member 112 side is “passed” when the opening / closing operation member 121 side is not operating. It is in a state where it can freely swing from the “blocking state” to the “passable state”. Therefore, even if the opening / closing operation member 121 does not operate normally due to some trouble, for example, the opening / closing member 112 has the blocking plate portion 115 side of the sliding plate portion 114 moved by the game ball moving on the firing rail 12 in the firing direction. It is elastically deformed in the direction in which it is pushed up, so that the blocking plate 115 can retreat upward from the passing space of the game ball and enter a “passable state”.

  The opening / closing drive means 119 is for operating the opening / closing operation means 118 in conjunction with the drive operation of the firing drive motor 66, the driven member 124 that is interlocked with the opening / closing operation means 118 side via the connecting member 120, and the firing drive. An opening / closing drive cam 125 that operates the driven member 124 in accordance with the drive operation of the motor 66 is provided.

  As shown in FIGS. 6, 8, etc., the driven member 124 is swingably attached to the mounting plate 70, for example, by a support shaft 126 in the front-rear direction. The driven member 124 is provided with a cam receiving shaft 127 in the front-rear direction on the swing end side thereof, and one end side of the connecting member 120 is fixed in the vicinity thereof, and the connecting member 120 is further connected by a spring means 128 (FIG. 8). It is biased in the pulling direction, that is, the direction in which the opening / closing member 112 is moved to the “passable state” side.

  The opening / closing drive cam 125 is fixed to the drive shaft 104 of the firing drive motor 66, and the cam receiving shaft 127 of the driven member 124 slides along the substantially circular outer edge side thereof. On the outer edge of the opening / closing drive cam 125, a recess 129 is formed at a predetermined position. When the driven member 124 passes through the recess 129, the connecting member 120 is pulled, so that the opening / closing member in the “passage prevention state”. 112 is moved to the “passable state” side.

  The concave portion 129 is positioned in the circumferential direction so that the opening / closing member 112 is in the “passable state” only during a predetermined period before and after the timing when the game ball launched by the hitting basket 63 passes through the opening / closing member 112. And the size is set. In addition, it is desirable to make the period when the opening / closing member 112 is in the “passable state” as small as possible.

  In the pachinko machine described above, when the player operates the launch handle 10 with the game balls for launch stored in the upper plate 11, the operation-side spring end member 102 is moved via the wire 65a according to the amount of operation. By rotating relative to the drive-side spring end member 101, the spring force of the firing spring means 65 increases.

  Further, the firing drive motor 66 is operated, and both the firing drive cam 105 and the opening / closing drive cam 125 start to rotate counterclockwise. Then, the firing drive cam 105 gradually pushes down the drive receiving portion 103 on the impact rod 63 side in the clockwise direction, so that the impact rod 63 resists the spring force of the firing spring means 65 from the initial position to the firing preparation position in the clockwise direction. (Fig. 10 (A)-> (B)).

  At that time, the ball feed driving unit 95 on the striking rod 63 side pushes the driven arm 97 to swing the ball feed interlocking means 64 in the counterclockwise direction, whereby the drive arm 96 pushes the roller 85 of the interlocking member 79 upward. Therefore (see FIG. 8), the ball feeding means 13 changes from the “ball feeding execution state” until then to the “ball feeding preparation state”, and the ball receiving member 77 swings around the pivot 83 and the ball feeding member 78. Rises and the ball stopper 87 moves away from the ball guide port 74 upward (FIG. 5 (A) → (B)). Therefore, one game ball in the ball guide port 74 falls from the ball guide port 89 onto the ball receiving member 77 and is held between the ball receiving portion 88 and the ball holding wall 84 on the cover 81 side. .

  When the firing drive cam 105 further rotates, the pushed-down state of the drive receiving portion 103 is released, and the striking rod 63 returns from the firing preparation position to the initial position at once by the spring force of the firing spring means 65 (hereinafter referred to as a striking operation) ( FIG. 10 (B) → (C)). At that time, the ball feed interlocking means 64 is moved downward from the roller 85 of the interlocking member 79, and the ball receiving member 77 and the ball feeding member 78 are lowered by the weight of the interlocking member 79. To “ball feed execution state” (FIG. 5B → (A)). As a result, the game ball held between the ball receiving portion 88 and the ball holding wall 84 on the cover 81 side falls and rolls on the ball receiving member 77, from the ball supply port 75 to the firing rail 12. Then, it is hit by the hitting rod 63 and fired toward the game area 21.

  Further, the cam receiving shaft 127 of the driven member 124 is substantially simultaneously with a predetermined timing before the game ball launched by the hitting operation passes the position of the opening / closing member 112, for example, hitting the game ball by the hitting rod 63. The recessed member 129 of the opening / closing drive cam 125 enters, and the driven member 124 swings by a predetermined angle in the counterclockwise direction by the spring means 128 (FIG. 10 (B) → (C)). As a result, the connecting member 120 is pulled, the engagement plate portion 116 of the opening / closing member 112 is pulled up by the opening / closing operation member 121 on the opening / closing operation means 118 side, and the opening / closing member 112 is changed from the “passage prevention state” to the “passage permission state”. .

  Therefore, since the game ball fired by the striking rod 63 passes on the firing rail 12 without contacting the opening / closing member 112, the opening / closing member 112 does not affect the firing accuracy, and the opening / closing member 112 is not deteriorated or damaged at an early stage due to repeated friction and impact received from the launch ball.

  When the projecting ball passes the position of the opening / closing member 112, the cam receiving shaft 127 of the driven member 124 is disengaged from the recess 129 of the opening / closing driving cam 125, and the driven member 124 swings clockwise to the original position against the spring means 128. Move (FIG. 10 (C) → (A)). As a result, the pulled connecting member 120 is loosened, and the opening / closing member 112 returns from the “passable state” to the “passage blocking state”. Therefore, the foul ball that has returned without reaching the game area 21 after launching is blocked by the opening / closing member 112 in the “passage prevention state” and reliably guided to the foul ball guide passage 57 side without returning to the firing rail 12. Is done.

  As described above, in the present embodiment, the return ball blocking means 111 is provided in the vicinity of the rear end portion 12b of the firing rail 12 and can be changed between the passage blocking state and the passage allowing state, and the opening and closing member 112. The interlocking means 113 for interlocking the member 112 with the driving operation of the firing drive motor 66 on the launching means 9 side is provided. The interlocking means 113 is a game ball in which the game ball fired by the launching means 9 is at the rear end portion 12b of the firing rail. Since the firing drive motor 66 and the opening / closing member 112 are connected so that the opening / closing member 112 is allowed to pass only within a predetermined period before and after the passage time of the passing space, the firing rail 12 of the foul ball is connected. It effectively prevents the return to the side, does not adversely affect the launch ball, and the opening / closing member 112 does not contact the launch ball, so that the deterioration Damage is not, there is an advantage in that it is not necessary to perform the maintenance of parts such as replacement frequently.

  FIG. 11 illustrates the second embodiment of the present invention, and shows an example in which the interlocking unit 113 is configured to mechanically interlock the ball feeding operation of the ball feeding unit 13 and the reciprocating operation of the opening / closing member 112. Yes.

  As shown in FIG. 11, the interlocking means 113 of this embodiment includes an opening / closing operation means 118 provided in the vicinity of the opening / closing member 112 and a connecting member 120 that connects the opening / closing operation means 118 side and the ball feeding means 13 side. And a connecting rocking member 131. Here, for the opening / closing member 112 and the opening / closing operation means 118, for example, the same configuration as in the first embodiment is adopted.

  As shown in FIG. 11, the ball feeding means 13 is elastically biased to the “ball feeding ready state” side by providing a spring member 132 for connecting the interlocking member 79 and the ball feeding case 76, for example. Other configurations of the ball feeding means 13 are substantially the same as those in the first embodiment.

  The connecting member 120 is fixed to, for example, the ball feeding member 78 on the ball feeding means 13 side, and moves, for example, up and down with the ball feeding operation on the ball feeding means 13 side. An opening / closing side connection member 134 made of a wire or the like fixed to the opening / closing operation member 121 of 121, and an interlocking connection member 135 for interlocking the ball feeding side connection member 133 and the opening / closing side connection member 134 are provided.

  The interlocking connecting member 135 has a ball feeding side connecting member 133 connected to one end side thereof, and an opening / closing side connecting member 134 connected to the other end side thereof. When the ball feed means 13 changes from the “ball feed execution state” to the “ball feed preparation state” and the ball feed side connection member 133 rises, the open / close side connection member 134 is supported. The opening / closing member 112 is changed from the “passage-preventing state” to the “passage-permitted state” via the opening / closing operation means 118.

  The spring force of the spring member 132 that urges the ball feeding means 13 from the “ball feeding execution state” to the “ball feeding preparation state” side causes the opening / closing member 112 to move from the “passing permission state” to the “passing prevention state” side. The spring force of the biasing spring member 123 and the opening / closing member 112 is set to be stronger.

  As in the first embodiment, the ball feed interlocking means 64 of this embodiment is formed in a substantially L shape with a driving arm 96 and a driven arm 97, and swings by a fixed shaft 98 in the front-rear direction at the bent portion. Although it is pivotally supported, its mounting position, mounting direction, interlocking operation and the like are slightly different from those of the first embodiment, and when the striking rod 63 is driven to swing clockwise, the driven arm 97 is pushed by the ball feed drive unit 95 and swings counterclockwise, whereby the drive arm 96 pushes the roller 85 of the interlocking member 79 downward against the spring force of the spring member 132. .

  The firing drive cam 105 is slightly different in shape from that of the first embodiment, and immediately after the game ball is hit by the hitting bar 63 and the game ball passes through the opening / closing member 112, the launch drive cam 105 is used. The pressing operation of the drive receiving portion 103 by the above, that is, the swinging operation of the striking rod 63 in the clockwise direction is started.

  Since the opening / closing member 112, the opening / closing operation means 118, the interlocking connecting member 135 and the like are provided on the lower set plate 18 side and the ball feeding means 13 are provided on the front plate 5 side, respectively, when the front plate 5 is opened, The engagement between the interlocking connecting member 135 and the ball feeding side connecting member 133 is temporarily released. In this case, when the front plate 5 is closed, the ball feeding side connecting member 133 is smoothly engaged with the interlocking connecting member 135 as it is, so that the state of the interlocking connecting member 135 is changed only while the front plate 5 is opened. It is desirable to provide locking means for locking. Of course, if the opening / closing member 112, the opening / closing operation means 118, the interlocking connecting member 135, etc. are provided on the same front plate 5 side as the ball feeding means 13, it is not necessary to release the connected state when the front plate 5 is opened / closed.

  In the pachinko machine of the present embodiment, in a state where the striking rod 63 is in the initial position (the position shown in FIG. 11A), the ball feeding means 13 is in the “ball feeding ready state” (FIG. 5B). The opening / closing member 112 is held in the “passable state”.

  When the firing handle 10 is operated from the state where the striking rod 63 is in the initial position, the firing drive motor 66 is actuated and the firing drive cam 105 starts to rotate counterclockwise. Immediately thereafter, the firing drive cam 105 begins to gradually push down the drive receiving portion 103 on the striking rod 63 side, and the striking rod 63 begins to swing clockwise against the spring force of the firing spring means 65. . At that time, the ball feed driving portion 95 on the striking rod 63 side pushes the driven arm 97 to swing the ball feed interlocking means 64 counterclockwise, whereby the drive arm 96 pushes the roller 85 of the interlocking member 79 downward. Therefore, the ball feeding means 13 changes from the “ball feeding preparation state” until then to the “ball feeding execution state” (FIG. 5 (B) → (A)), and the next game ball in the ball guiding port 74 is changed. While being received by the ball stopper 87, the game ball held between the ball receiver 88 and the ball holding wall 84 on the cover 81 side falls, rolls on the ball receiver 77, and supplies the ball supply port 75. To the firing rail 12.

  Further, when the ball feeding means 13 changes from the “ball feeding ready state” to the “ball feeding execution state”, it is maintained in the “passable state” until then through the connecting member 120 and the opening / closing operation member 121 on the opening / closing operation means 118 side. The opened opening / closing member 112 is changed to the “passage blocking state”. Therefore, the subsequent foul balls are blocked by the opening / closing member 112 in the “passage blocking state” and are reliably guided to the foul ball guide passage 57 side without returning to the firing rail 12.

  When the rotation of the firing drive cam 105 further proceeds and the striking rod 63 swings from the initial position to the firing preparation position (FIG. 11 (A) → (B)), the pushed state of the drive receiving portion 103 is released immediately thereafter, The hitting basket 63 returns from the launch preparation position to the initial position at once by the spring force of the launch spring means 65 (FIGS. 11B to 11C), and the game ball supplied on the launch rail 12 is moved by the saddle section 94. Strike and fire.

  At this time, the ball feed interlocking means 64 is disengaged upward from the roller 85 of the interlocking member 79, and the ball receiving member 77 and the ball feeding member 78 are raised by the spring force of the spring member 132. The state returns to the “ball feeding preparation state” (FIG. 5 (A) → (B)). Thereby, one game ball in the ball guide port 74 that has been stopped by the ball stopper 87 until then falls into the ball guide port 89, and the ball holder 88 and the ball holding wall 84 on the cover 81 side It will be in the state kept between.

  Further, at the same time when the ball feeding means 13 returns from the “ball feeding execution state” to the “ball feeding preparation state”, the opening / closing member 112 is placed in the “passage prevention state” via the connecting member 120 and the opening / closing operation member 121 on the opening / closing operation means 118 side. ”To“ passable state ”, the game ball fired by the hitting rod 63 passes on the firing rail 12 without contacting the opening / closing member 112, and the opening / closing member 112 affects the firing accuracy. There is no effect, and the opening / closing member 112 is not deteriorated or damaged at an early stage due to repeated friction and impact received from the launch ball.

  Then, immediately after that, the firing drive cam 105 starts to gradually lower the drive receiving portion 103 on the striking rod 63 side in the clockwise direction, and the opening / closing member 112 changes from the “passable state” to the “passage prevention state” at an early stage. Then, the return of the foul ball to the firing rail 12 side can be reliably prevented.

  FIG. 12 illustrates a third embodiment of the present invention, in which the ball feeding means 13 is configured to perform a ball feeding operation by driving a ball feeding driving means different from the firing drive motor 66 that drives the striking rod 63. In this example, the interlocking unit 113 is configured to mechanically interlock the driving operation on the side of the ball feeding driving unit and the reciprocating operation of the opening / closing member 112.

  The pachinko machine according to the present embodiment is provided with ball feed driving means 141 for driving the ball feed means 13. This ball feed driving means 141 is constituted by, for example, an electromagnetic solenoid, and is detachably mounted on, for example, the front side of the lower set plate 18 in a state where the drive shaft 142 is disposed in a substantially vertical direction. The ball feed driving means 141 is held in a state in which the drive shaft 142 protrudes downward by the spring member in the OFF (non-excitation) state, and resists the biasing force of the spring member when in the ON (excitation) state. It is assumed that the drive shaft 142 is configured to move upward.

  The ball feed driving means 141 is connected to the ball feed means 13 side by the ball feed drive connecting member 143 and to the opening / closing member 112 side by the interlocking means 113.

  For example, the lower end side of the drive shaft 142 of the ball feed driving means 141 is fixed to one end side of the ball feed drive connecting member 143, and the other end side is fixed to the ball feed member 78 or the like on the ball feed means 13 side. For example, a ball feed side connecting member 133 that reciprocates up and down together with the ball feed operation is rotatably connected to each other, and can be swung around the swing shaft 143a in the front-rear direction on the front side of the lower set plate 18 at an intermediate position. It is supported by.

  The interlocking means 113 includes an opening / closing operation means 118 provided in the vicinity of the opening / closing member 112, and an opening / closing drive connecting member 144 that connects the opening / closing operation means 118 side and the ball feed driving means 141 side. Here, for the opening / closing member 112 and the opening / closing operation means 118, for example, the same configuration as in the first embodiment is adopted.

  The opening / closing drive connecting member 144 is rotatably connected, for example, to the upper end side of the drive shaft 142 of the ball feed driving means 141 on one end side, and to the opening / closing operation member 121 side on the opening / closing operation means 118 side on the other end side. At the position, it is supported on the front side of the lower set plate 18 so as to be swingable around a swing shaft 144a in the front-rear direction, for example.

  Thereby, when the ball feed driving means 141 is OFF, the ball feed means 13 is in the “ball feed ready state”, and the open / close member 112 is in the “passable state”. When the ball feed drive means 141 is ON, the ball feed means 13 is turned on. Is “ball feeding execution state”, and the opening and closing member 112 is “passing prevention state”.

  The opening / closing member 112, the opening / closing operation means 118, the opening / closing drive connecting member 144, the ball feed driving means 141, the ball feed drive connecting member 143 and the like are provided on the lower set plate 18 side, and the ball feed means 13 is provided on the front plate 5 side. Therefore, when the front plate 5 is opened, the engagement between the ball feed drive connecting member 143 and the ball feed side connecting member 133 is temporarily released. In this case, when the front plate 5 is closed, the ball feed side connecting member 133 is smoothly engaged with the ball feed drive connecting member 143 as it is, so that the ball feed means 13 is only opened while the front plate 5 is open. It is desirable to provide locking means for locking the state. Of course, if the opening / closing member 112, the opening / closing operation means 118, the interlocking connecting member 135, etc. are provided on the same front plate 5 side as the ball feeding means 13, it is not necessary to release the connected state when the front plate 5 is opened / closed.

  During the firing operation, the ball feed driving means 141 is, for example, a period from the time when the striking ball 63 strikes the game ball by the launch control board 68 or almost immediately before the hit game ball passes through the opening / closing member 112. It is controlled to turn off only, and to turn on during other periods.

  In the pachinko machine of the present embodiment, when the striking rod 63 is in the initial position (the position shown in FIG. 12A), the ball feed driving means 141 is OFF and the ball feed means 13 is “ball feed”. In the “prepared state” (FIG. 5B), the open / close member 112 is held in the “passable state”.

  When the firing handle 10 is operated while the striking rod 63 is in the initial position, the firing drive motor 66 is actuated to start the firing drive cam 105 rotating counterclockwise, and the ball feed drive means 141 is turned on. Then, the ball feeding means 13 changes from the “ball feeding ready state” to the “ball feeding execution state” (FIG. 5 (B) → (A)), and the next game ball in the ball guiding port 74 is the ball. While being received by the stopper 87, the game ball held between the ball receiver 88 and the ball holding wall 84 on the cover 81 side falls and rolls on the ball receiver member 77 from the ball supply port 75. Supplied on the firing rail 12.

  At the same time, since the opening / closing member 112 held in the “passable state” is changed to the “passage blocking state”, the subsequent foul ball is blocked by the opening / closing member 112 in the “passage blocking state” and placed on the firing rail 12. It is reliably guided to the foul ball guide passage 57 side without returning.

  Thereafter, the firing drive cam 105 begins to gradually push down the drive receiving portion 103 on the striking rod 63 side, and the striking rod 63 begins to swing clockwise against the spring force of the firing spring means 65.

  When the rotation of the firing drive cam 105 further proceeds and the striking rod 63 swings from the initial position to the firing preparation position (FIG. 12 (A) → (B)), the pushed state of the drive receiving portion 103 is released immediately thereafter, The hitting rod 63 returns from the launch preparation position to the initial position at once by the spring force of the launch spring means 65 (FIG. 12B → (C)), and the game ball supplied on the launch rail 12 is moved by the saddle portion 94. Strike and fire.

  At that time, the ball feed driving means 141 is turned OFF, and the ball feed means 13 returns from the “ball feed execution state” to the “ball feed preparation state” (FIG. 5 (A) → (B)). Thereby, one game ball in the ball guide port 74 that has been stopped by the ball stopper 87 until then falls into the ball guide port 89, and the ball holder 88 and the ball holding wall 84 on the cover 81 side It will be in the state kept between. At the same time, the opening / closing member 112 changes from the “passage-preventing state” to the “passable state”, so that the game ball fired by the striking rod 63 passes on the firing rail 12 without contacting the opening / closing member 112. The opening and closing member 112 does not affect the firing accuracy, and the opening and closing member 112 is not deteriorated or damaged at an early stage due to repeated friction and impact received from the launch ball.

  Immediately after the launch ball passes through the opening / closing member 112, the ball feed driving means 141 is turned on, the ball feeding means 13 changes from the "ball feeding ready state" to the "ball feeding execution state", and the opening / closing member 112 is "passed" Since the state changes from the “allowable state” to the “passage blocking state”, the subsequent return of the foul ball to the firing rail 12 side can be reliably prevented.

  13 to 21 exemplify a fourth embodiment of the present invention. Similarly to the third embodiment, the ball feed driving means 141 different from the firing drive motor 66 in which the ball feed means 13 drives the striking rod 63 is shown. An example is shown in which the ball feeding operation is performed by driving the motor, and the interlocking unit 113 is configured to mechanically interlock the driving operation on the ball feeding driving unit 141 side and the reciprocating operation of the opening and closing member 112. Yes.

  The ball introduction port 163 communicates with the upper plate discharge port 151 when the front plate 5 is closed to the lower set plate 18 side. Further, as shown in FIG. 16, a fall prevention member 151 a is provided on the front plate 5 side to prevent the game ball from dropping from the upper dish discharge port 151 when the front plate 5 is opened. The fall prevention member 151a is formed to be movable between a closed state in which the upper plate discharge port 151 is closed and an open state in which the upper plate discharge port 151 is opened at a position in front of the closed state. When the front plate 5 is closed to the lower set plate 18 side, it is pushed forward by the bulging portion 175 on the ball feed case 165 side so as to change from the closed state to the open state. It has become.

  On the upper side of the ball supply passage 161, for example, a plate-like restricting plate 176 arranged substantially horizontally extends forward from the rear wall 173 on the rear cover body 171 side, and the front edge side of the restricting plate 176 is It is located in front of the bulging portion 175, that is, behind the ball feeding passage 162.

  The ball feeding member 166 includes a ball feeding operation unit 181 that regulates and guides the game ball flowing from the ball introduction port 163 to the ball feeding path 162 side, and the ball feeding operation unit 181 around the swing shaft 182 in the front-rear direction. A support arm portion 183 that is swingably supported is integrally provided.

  The ball feeding operation portion 181 includes an upper plate portion 184 disposed along the upper side of the restriction plate 176, a lower plate portion 185 disposed along the ball supply passage 161 below the restriction plate 176, and the upper plates. Front side in which the opposite side (left side) of the side plate part 186 opens toward the ball inlet 163 with the side plate part 186 that connects the part 184 and the lower plate part 185 vertically on one end side in the left-right direction, that is, the right end side. It is formed in a general U-shape.

  The ball feeding operation portion 181 is provided in the front-rear direction from the vicinity of the front side of the rear wall 173 on the rear cover body 171 side to the vicinity of the rear side of the front wall 174 on the front cover body 172 side. 162.

  The upper plate portion 184 has an inflow restricting portion 187 arranged at the front end side edge portion in the vicinity of the inner side of the ball introduction port 163, and further in the vicinity of the rear end side and at the rear side of the ball introduction port 163. The interlocking projection part 188 which protrudes on the opposite side (left side) of the side plate part 186 is integrally formed, for example.

  The lower plate portion 185 is formed, for example, in a downwardly inclined shape along the ball supply passage 161. Note that the distance between the upper plate portion 184 and the lower plate portion 185 of the ball feeding operation portion 181 is formed to be slightly larger than the diameter of the game ball.

  The support arm portion 183 is formed in a protruding shape on the back side (right surface side) of the side plate portion 186 of the ball feeding operation portion 181, and the ball feeding case 165 via the swing shaft 182 in the front-rear direction in the vicinity of the end portion. It is supported on the side so as to be swingable.

  On the upper surface side of the support arm portion 183, a driven piece 189 made of, for example, a metal plate is mounted between the swing shaft 182 and the ball feeding operation portion 181 so as to face the upper side of the driven piece 189. In addition, a ball feed driving means 141 made of, for example, an electromagnetic solenoid is mounted on the ball feed case 165 side.

  The ball feed driving means 141 swings and drives the ball feed member 166 in the vertical direction. When the ball feed drive means 141 is in an OFF (non-excited) state, the ball feed member 166 is lowered by its own weight, When the “feed execution state” is entered (FIG. 17) and the ON (excitation) state is established, the driven piece 189 is pulled toward the ball feed drive means 141 side and rises to the “ball feed preparation state” (FIG. 18). It has become.

  When the ball feeding member 166 is in the lowered state, that is, the “ball feeding execution state” (FIG. 17), the inflow restricting portion 187 of the upper plate portion 184 constituting the ball feeding operation portion 181 is The inflow restricting portion 187 is in an up state, that is, in a “ball feeding ready state” (FIG. 18), by blocking the portion from the inside to prevent the inflow of game balls from the upper tray discharge port 151 side to the ball feeding passage 162 side. By moving upward, the ball introduction port 163 is opened, and the inflow of game balls from the upper plate discharge port 151 side to the ball feeding passage 162 side is allowed.

  In the “ball feeding preparation state”, the lower plate portion 185 blocks a part of the ball supply passage 161 and prevents the game ball from flowing from the ball supply passage 162 side to the ball supply passage 161 side. The first game ball that has flowed into the ball payout passage 162 from the upper plate discharge port 151 via 163 is controlled in the front edge side of the restriction plate 176 and held in the ball feeding operation unit 181. When the lower plate portion 185 is lowered to the vicinity of the lower side of the ball supply passage 161 and the ball supply passage 161 is opened so as to be able to pass the game ball, It is guided by the plate portion 185 and flows down to the front side, and is supplied onto the firing rail 12 via the ball supply port 164.

  The opening / closing member 112 is disposed on the upper side of the ball feeding member 166 and protrudes rearward from the inside of the ball feeding case 165 through an opening 191 provided in the rear wall 173 on the rear cover body 171 side. The ball feeding case 165 is supported so as to be swingable about a swing shaft 193 in the front-rear direction via a swing arm 192 formed integrally. The swing shaft 193 is provided at a position obliquely above the upstream side of the opening / closing member 112 with respect to the game ball launch direction.

  On the lower side of the swing arm 192, an interlocked portion 194 that contacts the upper side of the interlocking protrusion 188 on the ball feeding member 166 side is formed integrally, for example, and the opening / closing member 112 faces downward due to its own weight. Oscillation is regulated by the interlocking protrusion 188 via the swinging arm 192 and the interlocked part 194, and the ball of the ball feeding member 166 is connected via the interlocking protrusion 188, the interlocked part 194 and the swinging arm 192. It moves up and down in conjunction with the feed operation.

  That is, the opening / closing member 112 is in a “passage blocking state” that blocks at least a part of the passing space of the game ball at the rear end 12b of the launch rail when the ball feeding member 166 is in the lowered state, that is, the “ball feeding execution state”. The foul ball is prevented from returning to the firing rail 12 side (FIGS. 17 and 19), and when the ball feeding member 166 is in the ascending state, that is, the “ball feeding ready state”, it rises in conjunction with it and launches. The game ball is allowed to pass in the launch direction by opening the space for passing the game ball at the rail rear end 12b (FIGS. 18 and 20).

  Here, the oscillating arm 192, the interlocked portion 194, the interlocking protrusion 188, the ball feeding member 166, and the like are interlocking means for mechanically interlocking the driving operation on the side of the ball feeding driving means 141 and the reciprocating operation of the opening / closing member 112. 113 is an example.

  In addition, the opening / closing member 112 includes a blocking plate portion 112a that is substantially in the vertical direction when in the “passage blocking state”, and extends from the lower side of the blocking plate portion 112a toward the upstream side in the firing direction. ”And the passage guide plate 112b that is inclined obliquely upward and upstream with respect to the firing direction. Thereby, the opening / closing member 112 can effectively prevent the return of the foul ball by the blocking plate portion 112a in the “passage blocking state”, and the game ball is launched without changing to the “passable state” for some reason. Even in such a case, it is possible to enter a “passable state” by the projecting ball colliding with the passage guide plate portion 112b and pushing up the opening / closing member 112 upward.

  During the launching operation, the ball feed driving means 141 is operated, for example, by the launch control board 68 from about the same time or immediately before the hitting ball 63 hits the game ball to immediately after the hit game ball passes through the opening / closing member 112. It is controlled so that it is ON only during this period and OFF during other periods.

  In the pachinko machine of the present embodiment, when the firing drive solenoid 66a is OFF and the striking rod 63 is in the firing preparation position (position shown in FIG. 21A), which is the initial position, the ball feed driving means 141 is OFF. The ball feeding means 13 is held in the “ball feeding execution state” and the opening / closing member 112 is held in the “passage blocking state”. For example, the game ball supplied by the previous ball feeding operation is launched on the launch rail 12. It is in a state of being held at the standby position Pa.

  When the firing handle 10 is operated from the state where the striking rod 63 is in the initial position (firing preparation position), the firing driving solenoid 66a is turned on, and the striking rod 63 swings clockwise toward the firing position.

  Then, when the hitting ball 63 hits the game ball at the firing standby position Pa, the ball feed driving means 141 is turned on substantially at the same time or immediately before, and the ball feed means 13 is changed from the “ball feed execution state” until then. It changes to the “ball feeding preparation state” (FIG. 21 (A) → (B)). At this time, the inflow restricting portion 187 moves upward due to the rise of the ball feeding member 166 to open the ball introduction port 163 and allow the inflow of game balls from the upper plate discharge port 151 side to the ball feeding passage 162 side ( FIG. 17 → FIG. As a result, the game ball flows into the ball delivery passage 162 from the upper plate discharge port 151 via the ball introduction port 163. However, in the “ball feeding preparation state”, the lower plate portion 185 moves a part of the ball supply passage 161. In order to block and prevent the game ball from flowing down from the ball supply passage 162 side to the ball supply passage 161 side, the first game ball that has flowed into the ball supply passage 162 has its rear side at the front edge side of the restriction plate 176. It is regulated and is held in the ball feeding operation unit 181.

  In conjunction with the upward movement of the ball feed member 166, the opening / closing member 112 held in the “passage blocking state” is changed to the “passable state”.

  The game ball hit by the striking ball 63 immediately after that passes through the firing rail 12 without contacting the opening / closing member 112, and the opening / closing member 112 does not affect the firing accuracy, and the opening / closing member 112. Is not deteriorated or damaged at an early stage by repeated friction and impact received from the launch ball.

  Immediately after the launch ball passes through the opening / closing member 112, the ball feed driving means 141 is turned off, and the ball feed means 13 changes from the “ball feed ready state” to the “ball feed execution state” (FIG. 21B → (C)). At this time, the lower plate portion 185 is lowered to the vicinity of the lower side of the ball supply passage 161 by the lowering of the ball feed member 166, and the ball supply passage 161 is opened so as to be able to pass the game ball. The game balls that have been made are guided by the inclined lower plate portion 185, flow down to the front side in the ball supply passage 161, and are supplied onto the firing rail 12 through the ball supply port 164. The subsequent game balls are lowered again and are prevented from flowing into the ball feeding passage 162 by the inflow restricting portion 187 that substantially closes the ball introduction port 163.

  Further, in conjunction with the downward movement of the ball feed member 166, the opening / closing member 112 changes from the “passable state” to the “passage blocked state”, so that the subsequent return of the foul ball to the firing rail 12 side is reliably prevented. it can.

  Here, even when the ball feeding member 166 is in the “ball feeding execution state” and is in the “passage blocking state”, the opening / closing member 112 can move upward against its own weight, that is, to the “passing permission state” side. Therefore, even if the game ball is launched without any change in the “passable state”, for example, due to some trouble, the passage guide plate portion is moved by the game ball moving in the firing direction on the launch rail 12. 112b is pushed upward, whereby the opening / closing member 112 can be retracted upward from the passing space of the game ball to be in a “passable state”.

  It should be noted that the firing drive solenoid 66a is turned off at a predetermined timing after the game ball is fired, for example, when the ball feeding means 13 changes from the “ball feeding ready state” to the “ball feeding execution state”, and the hitting rod 63 is fired. Return to the launch preparation position from the position.

  As mentioned above, although each embodiment of this invention was explained in full detail, it is not limited to this embodiment, A various change is possible within the range which does not deviate from the meaning of this invention. For example, the opening / closing member 112 and the opening / closing operation means 118 for performing the opening / closing operation thereof may be configured as shown in FIG. That is, the opening / closing member 112 is fixed so as to be allowed to pass, and when the opening / closing operation means 118 is not operated, the opening / closing member 112 is moved to the passage blocking state side by the spring member 123 on the opening / closing operation means 118 side via the opening / closing operation member 121. When the opening / closing operation means 118 is actuated and the opening / closing operation member 121 is lifted, the opening / closing member 112 may be returned to the passage permitted state by its own elastic force.

  Alternatively, as shown in FIG. 23, the opening / closing operation means 118 and the opening / closing member 112 may be integrally formed, for example, a part of the opening / closing operation member 121 on the opening / closing operation means 118 side is used as it is.

  The firing drive means 66 may be constituted by an electromagnetic solenoid or the like other than the motor. In this case, the interlocking means 113 may be configured to mechanically interlock the reciprocating driving operation on the firing driving means 66 side and the reciprocating operation of the opening / closing member 112.

  The ball feed driving means 141 may use, for example, a stepping motor other than the electromagnetic solenoid. In this case, the interlocking unit 113 may be configured to mechanically interlock the rotational driving operation on the ball feed driving unit 141 side and the reciprocating operation of the opening / closing member 112.

  In the embodiment, the example in which the interlocking unit 113 mechanically connects a predetermined driving unit such as the firing drive motor 66 and the ball feed driving unit 141 and the opening / closing member 112 is shown. The opening / closing member 112 is allowed to pass only within a predetermined period before and after the timing when the game ball launched by the ball passes through the space for passing the game ball at the rear end 12b of the launch rail, that is, the position of the opening / closing member 112. Any device may be used as long as the operation of the predetermined drive means and the opening / closing member 112 is coupled to each other, and the operation may be electrically linked via the control means. For example, a launch detection means for detecting the launch of a game ball, an open / close drive means such as a solenoid for operating the open / close member 112, and a control means for controlling the open / close drive means are provided. Based on the detection, the control unit may drive the opening / closing driving unit to change the opening / closing member 112 from the passage-blocking state to the passage-permitted state.

  In addition, although pachinko machine was illustrated in embodiment, it cannot be overemphasized that it can implement similarly with other ball game machines, such as an arrangement ball machine and a sparrow ball game machine. Moreover, a medal insertion type using a medal as a game medium, or a circulation type ball game machine that circulates a game ball between the launching means 9 and the game board 16 side may be used.
