Description

  The present invention relates to a pachinko machine in which a ball feeding device for sequentially sending game balls flowing out from a firing ball storage dish to a launching device is arranged in an inner frame.

  A typical pachinko machine includes a wooden outer frame fixed to the game island facility and a front frame attached to the outer frame through a hinge member so as to be opened and closed. The front frame mainly includes an inner frame having an opening for fixing the game board, a launching device, and the like. Further, on the front side of the inner frame, a front door provided with a launch ball storage tray for storing a game ball for launch and attached to the front side of the inner frame so as to be openable and closable is provided.

  The inner frame is provided with a launching device that launches a game ball below the game board and on the back side of the launch ball storage tray. The front side of the launching device is covered with a front door, and a launching ball storage tray is disposed on the front side of the front door covering the launching device. In addition, a ball feeding device is provided between the launching ball storage tray and the launching device to send game balls flowing out from the launching ball storage tray one by one to the launching device in accordance with the operation of the launching device. The ball feeding device is provided with a ball outlet for discharging the game ball flowing in from the launch ball storage tray to the front side of the machine body. The ball outlet is normally closed by a movable opening and closing piece, and the game ball that has flowed into the ball feeding device is sent to the launching device, but the opening and closing piece is operated on the front side of the front door. It is connected to the member, and when the opening and closing piece is moved by operating the ball removal operation member, the ball opening is opened, so that the game ball is discharged from the ball feeding device to the front side of the machine body (excess ball storage tray etc.) It has become.

  By the way, in many pachinko machines, a ball feeding device is provided on the back side of the front door, but in recent years, a configuration in which the ball feeding device is arranged in an inner frame has been proposed (Patent Document 1 and Patent Document 2). ). In such a configuration, since the ball feeding device is located on the inner frame side with the front door open, there is an advantage that maintenance of the ball feeding device can be performed quickly and easily. Here, in such a configuration, there is provided a movable ball stop member that blocks the ball outflow path on the rear side of the front door when the front door is opened and prevents the game ball from flowing out of the launch ball storage tray. Further, in this configuration, the ball removing operation piece connected to the ball removing operation member is disposed on the back side of the front door. This ball removal operation piece is separated from the opening / closing piece of the ball feeding device when the front door is open, but the opening / closing piece can be pressed when the front door is closed, and the ball removal operation piece is operated when the ball removal operation member is operated. The ball opening is opened when the operating piece pushes and moves the opening and closing piece.

  By the way, in the configuration in which the ball feeding device is arranged on the inner frame, the ball opening operation piece and the opening / closing piece are separated from each other when the front door is open, so that each can move independently. Depending on the position of the ball pulling operation piece, when the front door is closed, both may collide and be damaged. With respect to this problem, in the configurations of Patent Documents 1 and 2, the opening / closing piece is urged to a closed position that closes the ball opening, and the ball removing operation piece is urged to a steady position that does not press the opening / closing piece. When the front door is open, the opening and closing piece and the ball pulling action piece are biased and held at each position, so that when the front door is closed, the ball removing action piece does not collide with the opening and closing piece. It moves to a position where it can be pressed.

  However, even in the above configuration, the ball removal operation piece is mechanically linked to the ball removal operation member, so that when the front door is closed, the operator's hand carelessly touches the ball removal operation member. If this is the case, the ball removal operating piece may move from the steady position, and the opening / closing piece and the ball removal working piece may collide. In addition, when the ball removal operation member is accidentally operated with the front door open, the ball removal operation piece may be caught by the peripheral members and not return to the normal position. If it tries to close, the opening / closing piece and the ball pulling operation piece collide.

  An object of the present invention is to provide a pachinko machine that can solve such a problem.

  The present invention includes an inner frame provided with a launching device at a lower portion, a launching ball storage tray on a front surface, a front door pivotally supported on the front side of the inner frame so as to be able to be opened in one side, and an inner frame, A ball feeding device including a ball outlet for sequentially sending game balls flowing in from the ball storage tray to the launching device and discharging game balls flowing in from the firing ball storage tray to the front side of the machine body, and a ball of the ball feeding device An opening / closing piece disposed on the inner frame side so as to be movable between a closed position for closing the opening and a ball pulling position for opening, and being biased to the closed position by the first biasing means, A pachinko machine that is provided on the front side and includes a ball removal operation member that converts the open / close piece to a ball removal position by a player's operation, and is disposed on the front door and connected to the ball removal operation member. The normal position where the open / close piece can be pressed in the closed state of the front door and the open / close piece is closed by the second urging means. Energized, and by operating the ball removal operation member, the ball opening operation piece that is pressed into the operation position to press the opening and closing piece and to set the opening and closing piece to the ball removal position, and penetrating in the thickness direction of the front door, A ball outflow path for allowing the game ball of the launching ball storage tray to flow out to the back side of the front door, and a ball stop disposed on the front door and closing the ball outflow path by the third biasing means when the front door is open. Urged and held at a position, and in a closed state of the front door, is pressed by a pressure holding member disposed on the inner frame and held at an open position that opens the ball outflow passage against the urging force, and A pachinko machine comprising a movable ball stop member that engages with a ball pulling operation piece in a steady position at the ball stop position and prevents movement of the ball pulling operation piece to the operation position.

  Here, the “inner frame” according to the present invention refers to a frame that fixes the game board and that includes at least a launching device. In addition, the “front door” according to the present invention refers to one that is pivotally supported on the front side of the inner frame and that has at least a launching ball storage dish disposed on the front side. Further, the biasing means according to the present invention refers to a means using an elastic material such as a spring, a weight or the like. In the embodiment, the coil spring 69 corresponds to the first biasing means, the coil spring 82 corresponds to the second biasing means, and the coil spring 85 corresponds to the third biasing means.

  In such a configuration, when the front door is closed, the movable ball stop member is held at the open position, the ball outflow passage is opened, and the ball pulling operation piece is moved from the steady position according to the operation of the ball pulling operation member. When the front door is opened from such a state, the movable ball stop member is held at the ball stop position to block the ball outflow passage at the ball stop position, By engaging, the movement of the ball pulling operation piece to the operation position is prevented. Therefore, in the pachinko machine of the present invention, in the open state of the front door, even if the ball pulling operation member is operated, the ball pulling operation piece remains held at the steady position. There is no collision with the opening and closing pieces.

  In the present invention, the mode of blocking the movement of the ball pulling operation piece by the movable ball stopping member is not particularly limited. For example, an engagement portion may be provided on the ball removal operation piece, and the movable ball stop piece may be engaged with the engagement portion, or the movable ball stop member may be displaced to a position that blocks the movement path of the ball removal operation piece. You may make it make it. The movable ball stop member is set so that its movement direction is substantially perpendicular to the movement direction of the ball removal operation piece so that the movable ball stop member is not driven by being pushed by the ball removal operation piece in the engaged state with the ball removal operation piece. It is desirable to do.

  Specifically, the ball removal operation member is disposed on the front side of the front door so as to be able to be pushed down, and the ball removal operation piece is disposed so as to be movable in the width direction of the front door. Furthermore, it is disposed on the front door so as to be tiltable, abuts on the ball removal operation member and the ball removal operation piece, and moves the ball removal operation piece in the width direction of the front door as the ball removal operation member is pushed down. A configuration including a connecting member that is displaced from the steady position to the operating position is proposed. In such a configuration, the push-down operation of the ball removal operation member is converted into the movement of the ball removal operation piece along the width direction of the front door by the connecting member.

  The opening / closing piece includes a pressure-receiving protrusion protruding forward of the inner frame, and is disposed so as to be movable in the width direction of the inner frame. The ball-opening operation piece moves in the width direction of the front door. It is possible to press the pressure receiving protrusion of the opening and closing piece when the front door is closed, and the opening and closing piece is moved from the closed position to the ball by pressing the pressure receiving protrusion when moving from the steady position to the operating position. A configuration is also proposed which converts to the unplug position. In such a configuration, in the closed state of the front door, the opening and closing piece is displaced to the ball extraction position by pressing the pressure receiving projection by the ball extraction operation piece, and, in the open state of the front door, When the operator directly presses the pressure receiving projection, the opening / closing piece can be displaced to the ball removal position.

  By the way, in the above configuration, since the opening / closing piece is biased to the closed position, if the ball pulling operation piece pressing the opening / closing piece to the ball pulling position returns to the steady position, the opening / closing piece is moved by the biasing force. It will return from the ball removal position to the closed position. However, in such a configuration, the opening / closing piece may be caught by a peripheral member or an abnormality may occur in the biasing means, and may not return to the steady position but may remain in the ball extraction position. In such a case, since an abnormality of the opening / closing piece cannot be confirmed by the player, there is a possibility that the gaming ball is supplied to the ball feeding device with the ball outlet opened. For this reason, in the above configuration, the ball pulling operation piece is formed in the thickness direction of the front door and includes a pressing hole portion that fits with the pressure receiving protrusion of the opening and closing piece in the closed state of the front door. Is proposed. In such a configuration, since the pressing hole is externally fitted to the pressure receiving projection in the closed state of the front door, the ball pulling operation piece is different from the opening / closing piece even when the opening / closing piece returns to the steady position. It will be linked. For this reason, in this configuration, when the opening / closing piece remains in the ball removal position, the ball removal operation piece also remains in the operation position, and further, the ball removal operation member linked to the ball removal operation piece remains in the operated state. Become. Therefore, when the player stops the operation of the ball removal operation member, the player can confirm whether or not the opening / closing piece has returned to the closed position depending on whether or not the ball removal operation member returns to the original state. In such a configuration, the pressing hole portion of the ball pulling operation piece and the pressure receiving protrusion portion of the opening / closing piece are separated in the open state of the front door, so that the pressing hole portion is closed when the front door is closed. However, such a problem can be solved if the ball pulling operation piece is held in a steady position with the front door opened as in the present invention.

  Further, it is arranged on the movable ball stop member or the ball pulling operation piece, and the ball pulling operation piece moves toward the operation position in the engaged state between the ball stop position at the ball stop position and the ball pulling operation piece at the steady position. When the ball pulling operation piece presses the movable ball stop member, it is connected to a ball pulling operation detecting means for detecting the press and outputting a ball pulling abnormal signal, and a ball pulling operation detecting means, and A configuration is also proposed that includes ball removal abnormality notification control means that activates predetermined notification means upon reception. Here, the ball extraction operation detecting means is constituted by a sensor for collision detection, and the pressure sensor corresponds to this in the embodiment. Further, the ball removal abnormality notification control means is constituted by a substrate provided with a CPU, and the main control substrate corresponds to this in the embodiment. Further, the notification means is constituted by, for example, a lamp, various display devices, a speaker, and the like.

  In such a configuration, when the ball removal operation member is operated with the front door opened and the ball removal operation piece is blocked by the movable ball stop member at the ball stop position, the ball removal operation detection means detects this. Then, a ball removal abnormality signal is transmitted, and in response to this, the ball removal abnormality notification control means operates the notification means. For this reason, the operator can recognize that the ball removal operation member is improperly operated by the operation of the notification means. In such a configuration, in the closed state of the front door, the movable ball stop member does not lock the ball pulling operation piece, so the ball pulling operation detecting means does not transmit a ball pulling abnormality signal. In a case where the ball removal abnormality signal is transmitted in the closed state, the ball removal abnormality notification control means may not operate the notification means in the closed state of the front door. A normal pachinko machine is provided with a sensor for detecting the open state of the front door, and such a configuration can be easily realized by using a detection signal of such a sensor.

  As described above, according to the present invention, the movable ball stop member is engaged with the ball pulling operation piece in the steady position at the ball stop position that closes the ball outflow path, and the ball pulling operation piece is moved to the operating position. Therefore, when the front door is in the open state, the ball removal operating piece is held at the steady position even if the ball removal operation member is operated. The operating piece and the open / close piece do not collide. Therefore, in the pachinko machine of the present invention, the ball pulling operation piece and the opening / closing piece are not easily damaged when the front door is closed, and the operator needs to be careful not to operate the ball pulling operation member when the front door is open. Absent. Further, the present invention uses the existing movable ball stop member to prevent the movement of the ball pulling operation piece, and therefore has an advantage that it can be realized with a simple configuration without increasing the number of parts.

  In addition, a pressure receiving protrusion that protrudes forward of the inner frame is provided on the opening and closing piece, so that the ball pulling operation piece can press the pressure receiving protrusion in the closed state of the front door, and with the movement from the steady position to the operating position When the opening / closing piece is converted to the ball extraction position, the opening / closing piece can be easily converted to the ball extraction position by directly operating the pressure receiving projection in the opened state of the front door.

  Further, in the above configuration, when the ball removal operation piece is formed in the thickness direction of the front door and includes a pressing hole portion that fits with the pressure receiving protrusion of the opening and closing piece in the closed state of the front door. When the operation of the ball removal operation member is stopped, whether or not the opening / closing piece has returned to the closed position can be confirmed by the return state of the ball removal operation member.

  Further, when the ball removal operation detecting means and the ball removal abnormality notification control means are provided, it is possible to notify the player that the ball removal operation member is improperly operated in the front door open state.

As a result, in the ball pulling operation piece 43, as the sliding plate portion 77 slides, the pressing recess 83 presses the opening / closing piece 70 to set the ball pulling position β, and the pressing recess 83 has It can move to a steady position ε that does not press the opening and closing piece 70 (see FIG. 15). As shown in FIG. 13, a connecting shaft 79 for connecting to a connecting member 80 described later is formed on the front surface side of the sliding plate portion 77.

  15 and 16 show the arrangement and connection mode of the ball removal operation piece 43 and the ball removal operation member 42 arranged on the front door 6 from the back side. As shown in FIG. 15, the ball pulling operation member 42 is a button-shaped resin piece, and is pivotally supported when the lower right part in the figure is pivotally supported and the upper end exposed on the front side of the front door 6 is pushed down. It is like that. Further, as shown in FIG. 15, an attachment mechanism plate 46 made of a metal plate is disposed on the front side of the panel plate 41 of the front door 6. On the plate surface of the attachment mechanism plate 46, a connecting member 80 for connecting the ball removing operation member 42 and the ball removing operation piece 43, the movable ball stopping member 44, and the like are attached. As shown in FIG. 15, the connecting member 80 is made of a resin plate piece having a long triangular shape, and in the position directly below the ball removal operation unit 42, the short side is directed upward and the upper right corner in the figure. Are supported so that the lower end portion thereof is tilted left and right along the attachment mechanism plate 46. As shown in FIG. 15, one end of a coil spring 82 is connected to the left side of the connecting member 80 in the figure. The connecting member 80 is urged to the left in the drawing by the coil spring 82, and the short piece is brought into contact with the lower bottom surface of the ball removing operation unit 42. According to such a configuration, when the ball removal operation member 42 is pushed down, as shown in FIG. 15B, the lower end portion of the connecting member 80 tilts to the right in the figure, and the ball removal operation member 42 is pushed down. When stopped, the lower end portion of the linking member 80 returns to the left in the figure, and the pushed-out ball operating member 42 is pushed upward by the linking member 42.

  A connecting hole portion 81 in the front-rear direction is formed at the lower end portion of the connecting member 80, and the connecting member 80 is externally fitted to the connecting shaft 79 of the ball removing operation piece 43 by fitting the connecting hole portion 81 to the connecting shaft 79. The operating piece 43 is connected. As shown in FIG. 15A, the ball removal operating piece 43 is located at the steady position ε when the ball removal operation member 42 is not operated. As shown in FIG. When 42 is pushed down, it will be displaced to the operating position ζ following the tilting of the connecting member 80.

  The movable ball stop member 44 is composed of a horizontally long resin piece. As shown in FIG. 16, the right end portion in the figure is pivotally supported by the mounting mechanism plate 46 above the ball outflow passage 39, and the left end in the horizontal direction. A ball stop position γ that closes the ball outflow passage 39 from the rear by a ball stop tongue portion 84 formed at the center lower portion thereof, and a ball stop tongue portion 84 that is positioned above the ball outflow passage 39 with the left end in the figure facing upward. It can be displaced to the open position δ to be retracted. As shown in FIG. 16, a coil spring 85 is attached to the left side of the movable ball stop member 44, and the movable ball stop member 44 is urged toward the ball stop position γ by the coil spring 85. At the left end portion of the movable ball stop member 44 in the figure, a pressure receiving projection 86 that abuts against the press holding member 67 of the ball feeding device 15 is projected to the left in the drawing. As shown in FIG. 16A, when the front door 6 is closed, the movable ball stopping member 44 is held at the open position δ by pushing up the pressure receiving protrusion 86 by the pressing holding member 67. In addition, a stopper portion 87 that restricts the ball pulling operation piece 43 protrudes downward from the lower left end of the movable ball stop member 44. As shown in FIG. 16B, the movable ball stop member 44 has a stopper portion on the right side of the upper right corner of the sliding plate portion 77 of the ball pulling operation piece 43 at the steady position ε at the ball stop position γ. 87 is located, and thereby engages with the ball pulling operation piece 43. In such a state, since the moving direction of the ball removal operation piece 43 and the movement direction of the movable ball stop member 44 are orthogonal to each other, an attempt is made to move the ball removal operation piece 43 in the operation position ζ direction (rightward in the figure). Then, it collides with the stopper portion 87, and the movable ball stop member 44 is prevented from moving so as to stretch left and right.

Next, a manner of discharging the game ball from the ball feeding device 15 will be specifically described.
In the closed state of the front door 6, as shown in FIG. 17A, the pressing recessed portion 83 of the ball removing operation piece 43 is located on the right side of the pressure receiving projection 74 of the opening / closing piece 70. As described above, when the ball removal operation member 42 is not operated, the ball removal operation piece 43 is held at the steady position ε, and the opening / closing piece 70 is closed by the coil spring 69 as shown in FIG. Is held energized. For this reason, when the launch lever 29 is operated to rotate in such a state, the game balls are sent one by one onto the launch rail 18 by the ball feed mechanism of the ball feeder 15 and are launched into the game area 12.

  When the ball removal operation member 42 is pushed down while the front door 6 is closed, the ball removal operation piece 43 moves to the left operation position ζ, as shown in FIGS. 11 (b) and 17 (b). Displacement is performed, and the opening / closing piece 70 is pressed to the ball extraction position β to open the ball extraction port 61. Thereby, the game ball x in the ball feeding device 15 flows out from the ball outlet 61 to the ball outlet passage 62 and is discharged from the ball outlet 24 to the surplus ball storage tray 11 as shown in FIG. . Further, in this state, the ball outflow path 39 is open, so that the game ball x of the firing ball storage tray 10 also flows into the ball feeder 15 and is discharged to the surplus ball storage tray 11. When the operation of the ball pulling operation member 42 is stopped, the ball pulling operation piece 43 is returned to the steady position ε by the urging force of the coil spring 82 coupled to the connecting member 80, and the opening / closing piece 70 is returned to the closed position α and the ball discharge port 61 becomes a closed state. In the ball feeder 15 of the present embodiment, as shown in FIG. 11A, the lever member 58 that blocks the game ball x is flat at the upper end. The game ball x on the member 58 remains on the lever member 58 without being discharged. However, if the upper end portion of the lever member 58 is inclined toward the ball outlet 61, the lever member 58 is opened when the ball outlet 61 is opened. The above game ball x can also be discharged.

  Further, when the closed front door 6 is opened, as shown in FIG. 17C, the ball pulling operation piece 43 rotates forward, and the pressing recess 83 and the pressure receiving projection 74 are separated from each other. In such a state, the opening / closing piece 70 is urged and held in the closed position α unless the pressure receiving projection 74 is directly operated. On the other hand, when the front door 6 is opened, the movable ball stop member 44 is pushed up to the open position δ as shown in FIG. Accordingly, the ball spring is tilted to the ball stop position γ by the biasing force of the coil spring, and the ball outflow passage 39 is closed. Thereby, the outflow of the game ball from the firing ball storage tray 10 is prevented in the opened state of the front door 6. Further, as shown in FIG. 16B, in a state where the movable ball stop member 44 is at the ball stop position γ, the ball pulling operation piece 43 is prevented from being displaced to the operation position ζ by the movable ball stop member 44. For this reason, in the open state of the front door 6, even if the ball removal operation member 42 is pushed down, the ball removal operation piece 43 collides with the movable ball stop member 44 and is held at the steady position ε.

  When the front door 6 in the open state is closed, as shown in FIG. 17A, the open / close piece 70 and the ball pulling operation piece 43 which have been separated approach each other and press the pressure receiving projection 74 by the pressing recess 83. It becomes possible. As described above, since the ball pulling operation piece 43 is held at the steady position ε when the front door 6 is open, the pressure receiving projection 74 and the pressing recess 83 collide when the front door 6 is closed. Absent. Further, the ball stop position γ is pushed up by the pressure holding member 67 of the ball feeder 15 and returns from the ball stop position γ to the open position δ, whereby the game ball is transferred from the launch ball storage tray 10 to the ball feeder 15. Can flow in.

  As described above, in the pachinko machine according to the present embodiment, when the front door 6 is opened, the movable ball stop member 44 is displaced to the ball stop position γ. 43 is prevented from moving to the operating position ζ. Therefore, in this embodiment, in the opened state of the front door 6, even if the ball removal operation member 42 is operated, the ball removal operation piece 43 is held at the steady position ε. The front door 6 can be reliably closed without causing a collision. Therefore, in the pachinko machine 1 according to the present embodiment, the ball removal operation piece 43 and the opening / closing piece 70 are not easily damaged, and the operator collides the ball removal operation piece 43 and the opening / closing piece 70 when the front door 6 is closed. There is no need to be careful not to let them. Further, in this embodiment, since the ball removal operation piece 43 is locked by the existing movable ball stop member 44, the position conversion of the ball removal operation piece 43 can be prevented without increasing the number of parts.

Next, a modified example in which the configuration of the ball removing operation piece is changed from the above embodiment will be described.
FIG. 19 is a perspective view of a modified ball removal operation piece 43a. Comparing the ball pulling operation piece 43a with the ball pulling operation piece 43 of the above embodiment, the ball pulling operation piece 43 of the above embodiment has a depressed depression at the center at the left end of the pressing arm portion 78 as shown in FIG. 19 is provided with an O-shaped pressing hole 93 penetrating back and forth at the left end of the pressing arm 78, as shown in FIG. In the closed state of the front door 6, the pressing hole 93 is fitted on the pressure receiving projection 74 of the opening / closing piece 70.

  According to such a configuration, the opening / closing piece 70 and the ball removal operating piece 43a are interlocked to the left and right when the front door 6 is closed. For this reason, when the opening / closing piece 70 is caught in the ball removal position β in the closed state of the front door 6, the ball removal operation piece 43 is locked at the operation position ζ, and the ball removal operation member 42 remains in the depressed state. It becomes. Therefore, in this modification, there is an advantage that the player can confirm whether or not the opening / closing piece 70 has returned to the closed position α normally by checking whether or not the ball removing operation member 42 has returned upward. The pressing hole 93 shown in FIG. 19 has the same hole shape in the front and rear, but a taper is formed at the rear of the pressing hole 93 so that the pressure receiving protrusion 74 and the pressing hole 93 are formed. It is good to make it easy to fit.

Next, another modified example in which the above embodiment is further modified will be described.
In this modified example, in addition to the configuration of the pachinko machine 1 of the above-described embodiment, the ball pulling operation piece 43 operates in an engaged state of the movable ball stop member 44 at the ball stop position γ and the ball pulling operation piece 43 at the steady position ε. When the ball removal operating piece 43 moves in the direction ζ and presses the movable ball stop member 44, a ball removal operation detecting means for detecting the pressure and outputting a ball removal abnormality signal, a ball removal operation detecting means, It is connected and has a ball removal abnormality notification control means for operating a predetermined notification means when receiving a ball removal abnormality signal.

  This modification will be described in detail with reference to FIG. 16 of the above embodiment. The movable ball stop member 44 of this modification has a pressure-sensitive sensor on the surface of the stopper portion 87 that contacts the ball removal operation piece 43. As shown in FIG. 16B, the ball removal operation member 42 is operated in a state where the movable ball stop member 44 is at the ball stop position γ, and the ball removal operation piece 43 is moved to the operation position ζ. When it moves in the direction and collides with the stopper portion 87, the pressure sensor detects this and outputs a predetermined ball removal abnormality signal. The pressure-sensitive sensor is connected to the main control board, and when the main control board receives a ball removal abnormality signal, it activates a speaker (not shown) to generate a notification sound in a predetermined mode.

  Therefore, in this modified example, it is possible to notify the player that the ball removal operation member 42 is inappropriately operated in the opened state of the front door 6.

  The pachinko machine of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention. For example, in the above embodiment, the ball feeding device is pivotally supported by the firing mechanism plate, but the ball feeding device may be directly fixed to the inner frame. Further, in the above embodiment, the visual recognition opening 34 is provided in the front door 6, but the visual recognition opening 34 may be pivoted separately from the firing ball storage tray 10.
