  As shown in FIG. 2, the supply dish 6 stores the pachinko spheres 7 and has the stored pachinko spheres 7 arranged outside the pachinko machine 2 on the storage surface 6 a inclined so as to flow down the stored pachinko spheres 7. A discharge opening 6b for discharging toward the storage box is formed. The supply tray 6 is formed with a receiving opening 6c, a storage portion 6d, a supply passage (supply portion) 6e, and a ball flow lower slope 6f. The supply tray 6 receives the pachinko balls 7 to be paid out from the receiving opening 6c, and stores the received pachinko balls 7 in the storage portion 6d. The pachinko spheres 7 stored in the storage unit 6d are caused to flow down to the ball flow lower slope 6f provided on the upstream side of the supply passage (supply unit) 6e. The supply passage 6e supplies the pachinko ball 7 which has flowed down the ball flow lower slope 6f to the ball launching device. The discharge opening 6b is formed in the storage portion 6d on the upstream side of the spherical flow lower slope 6f. In this embodiment, the supply tray 6 is formed in a size that can store 200 pachinko balls 7.

  A ball discharge unit 20 (see FIG. 3) having a base opening 21b is attached to the back surface of the supply tray 6 opposite to the storage surface 6a by screws or the like. The ball discharge unit 20 is detachably attached to the back surface of the supply tray 6 opposite to the storage surface 6a (internal space covered by the supply tray 6). When the ball discharge unit 20 is attached to the supply tray 6, the discharge is performed. The opening 6b communicates with the base opening 21b (see FIG. 3).

  As shown in FIGS. 3, 4, and 5, the ball discharge unit 20 includes a base plate 21, a shutter 22 that shields and opens the base opening 21 b, a link lever (link member) 23, and a pushing portion 24 a. The contact portion (the holding portion 23e of the link lever 23) that has been pushed in is held in the pushing position by being pushed in until the amount reaches, and the holding portion 23e is released when the pushing portion 24a is pushed in again from this state. A push lock device (holding means) 24 and a torsion spring (shutter biasing means) 25 are attached.

  The base plate 21 is formed in a plate-like main body portion 21 a with a base opening 21 b that communicates with the discharge opening 6 b of the supply tray 6 and discharges the pachinko balls 7 stored in the supply tray 6 to the outside of the pachinko machine 2. ing. Wall-shaped ribs surrounding the outer peripheral portion are erected on the main body portion 21a. The pachinko balls 7 that have passed through the discharge opening 6b and the base opening 21b are discharged to the outside of the pachinko machine 2 from below the supply tray 6 through a discharge path (not shown).

  The main body portion 21a of the base plate 21 includes a shutter shaft portion 21c on which the shutter 22 is pivotally supported, a link shaft portion 21d on which the link lever 23 is pivotally supported, a lock attachment portion 21e to which the push lock device 24 is attached, A shutter receiving rib 21f serving as a receiving portion for restricting the vertical position when the shutter 22 is rotated, and a link lever receiving member serving as a receiving portion for restricting the vertical position when the link lever 23 is rotated. A rib 21g, a spring stopper rib 21h that engages with the first arm portion 25b of the torsion spring 25, a rotation regulating rib 21i that regulates the rotation of the shutter 22 and positions the shutter 22 at a position that shields the base opening 21b. , Is formed. The shutter receiving rib 21f and the link lever receiving rib 21g are formed in an arc shape.

  The shutter shaft portion 21c is inserted into the insertion hole 22c of the shutter 22, and has a diameter slightly smaller than that of the insertion hole 22c. The shutter shaft portion 21c is formed with a length that slightly protrudes from the upper surface of the shutter 22 when inserted through the insertion hole 22c.

  The link shaft portion 21d is inserted into the insertion hole 23d of the link lever 23, and is formed with a diameter slightly smaller than the insertion hole 23d. The link shaft portion 21d is formed with a length that slightly protrudes from the upper surface of the link lever 23 when inserted into the insertion hole 23d. Mounting holes 21j are formed in the shutter shaft portion 21c and the link shaft portion 21d, respectively.

  The shutter 22 is rotatable between a shielding position that shields the base opening 21b (see FIG. 5A) and an open position that opens (exposes) the base opening 21b (see FIG. 5B). It is attached to the shaft portion 21c. In the shutter 22, a shielding portion 22b for shielding the base opening 21b is formed integrally with the main body portion 22a. The body portion 22a has an insertion hole 22c through which the shutter shaft portion 21c is inserted, a spring compression rib 22d that engages with the second arm portion 25c of the torsion spring 25, and a first arm portion (the other end) of the link lever 23. An abutting boss 22e that abuts on 23b is formed. The spring compression ribs 22d and the contact bosses 22e are formed so as to protrude from the lower surface of the main body portion 22a, and further formed so as to be separated so that the torsion spring 25 can be disposed on the lower surface of the main body portion 22a. On the upper surface of the shielding part 22b, a rattling prevention convex part 22f that suppresses rattling in the vertical direction when the shutter 22 rotates is formed in an arc shape. Two rattling-preventing protrusions 22f are formed.

  The link lever 23 rotates between a holding position (see FIG. 5B) held by the pushing portion 24a of the push lock device 24 and a holding releasing position (see FIG. 5A) where the holding is released. It is possible to attach to the link shaft portion 21d. The link lever 23 is formed in a long plate shape, and a first arm portion (other end) 23b that abuts on a contact boss 22e of the shutter 22 on a columnar main body portion 23a provided at a substantially central portion in the longitudinal direction. And a hook-like second arm portion (one end) 23c that abuts against the abutment rib 32c of the ball discharge operation lever (operation member) 32 are integrally formed. The body portion 23a is formed with an insertion hole 23d through which the link shaft portion 21d is inserted. The first arm portion 23b is formed with a hook-like holding portion 23e that is pushed in and pushed by the pushed-in portion 24a of the push-lock device 24. When the link lever 23 rotates in the clockwise direction (from the holding release position toward the holding position), which is the direction in which the pushing portion 24a is pushed by the holding portion 23e, the first arm portion 23b comes into contact with the contact boss 22e of the shutter 22. The shutter 22 rotates from the shielding position to the open position.

  The torsion spring 25 includes a central portion 25a wound in a coil shape as a main body, and a first arm portion 25b and a second arm portion 25c that extend linearly outward from the central portion 25a.

  When the first arm portion 25b is brought into contact with the inner surface of the spring stopper rib 21h of the base plate 21 and the second arm portion 25c is rotated counterclockwise, the first arm portion 25b is counterclockwise and the second arm portion 25c is Rotational force is generated to rotate each clockwise. When the second arm 25c is brought into contact with the inner surface of the spring compression rib 22d of the shutter 22, the first arm 25b is locked to the spring stopper rib 21h and the second arm 25c is locked to the spring compression rib 22d. The torsion spring 25 is fixed. Accordingly, the spring compression rib 22d is rotated clockwise by the torsion spring 25, and the shutter 22 is urged (rotated clockwise) toward the shielding position.

  The shutter 22 urged clockwise by the spring compression rib 22d being rotated clockwise by the torsion spring 25 is restricted from rotating by contacting the rotation restricting rib 21i, and is positioned at the shielding position. That is, the shutter 22 is always located at the shielding position when an external force that rotates counterclockwise is not applied. When the shutter 22 rotates, the lower surface of the shielding portion 22b is in contact with the upper surface of the arcuate shutter receiving rib 21f, and the rattling prevention convex portion 22f of the shielding portion 22b is in contact with the upper surface of the inner surface of the supply tray 6. Rotates while touching. Thereby, the backlash of the shutter 22 at the time of rotation can be suppressed.

  When attaching the shutter 22 to the base plate 21, the shutter shaft portion 21c is inserted into the insertion hole 22c, and then a screw is screwed into the attachment hole 21j of the shutter shaft portion 21c. As described above, the shutter shaft portion 21 c is formed with a length that slightly protrudes from the upper surface of the shutter 22. Thereby, the shutter 22 is rotatably attached to the base plate 21.

  When attaching the link lever 23 to the base plate 21, the link shaft portion 21d is inserted into the insertion hole 23d, and then the screw is tightened into the attachment hole 21j of the link shaft portion 21d. As described above, the link shaft portion 21 d is formed with a length that slightly protrudes from the upper surface of the link lever 23. Thereby, the link lever 23 is attached to the base plate 21 rotatably.

  The abutment boss 22e of the shutter 22 is pivotally supported (rotated) clockwise by a torsion spring 25, with the shutter 22 supported by the shutter shaft 21c and the link lever 23 supported by the link shaft 21d. The first lever 23b contacts the link lever 23 and is biased counterclockwise. Thereby, the link lever 23 is always located at the holding release position (see FIG. 5A) when no external force is applied. The link lever 23 is restricted from rotating counterclockwise when the first arm 23b abuts against the side surface of the shutter receiving rib 21f of the base plate 21.

  The push lock device 24 is a well-known technique and will not be described in detail. However, the push lock device 24 includes a pushing portion 24a, and the link lever 23 rotates clockwise from the holding release position (see FIG. 5A). When the holding portion 23e of 23 pushes the pushing portion 24a, the holding portion 23e is held by the pushing portion 24a to hold the link lever 23 in the holding position, and the link is resumed from this state (the link lever 23 is the holding position). When the lever 23 rotates clockwise and the holding portion 23e pushes the pushing portion 24a again, the holding of the holding portion 23e is released. The push lock device 24 is attached to the lock attachment portion 21 e of the base plate 21.

  As shown in FIG. 2, a side cover 31 for exposing and shielding the ball launcher is attached to the left side of the supply tray 6 so as to be openable and closable in the front-rear direction. A ball discharge operation lever (operation member) 32 is attached to the side cover 31 so as to be slidable in a linear direction. The ball discharge operation lever 32 slides to rotate the link lever 23 clockwise, thereby rotating the shutter 22 from the shielding position to the open position, and discharging the pachinko ball 7 stored in the supply tray 6 to the outside. Is for. The ball discharge operation lever 32 is attached to the side cover 31 so that the handle portion 32b (see FIG. 5) protrudes from the front surface of the side cover 31 and can be operated (slided) by the player. When the front door 5 is closed, the side cover 31 cannot be opened or closed by covering the upper end of the side cover 31 with the lower end of the front door 5, and the front door 5 is unlocked with the release key. When the front door 5 is opened, it can be freely opened and closed. When the side cover 31 is opened, the ball discharge operation lever 32 is released from the reference position (initial position) where it comes into contact with the second arm portion (one end) 23c of the link lever 23.

  As shown in FIG. 5, the ball discharge operation lever (operation member) 32 includes a plate-like main body portion 32 a, a handle portion 32 b that serves as a handle when the player operates, and a second arm portion ( An abutment rib 32c that abuts one end) 23c and a spring attachment portion 32d that protrudes toward the pachinko machine 2 for attaching a coil spring (operation biasing means) 33 are formed. A spring insertion shaft 32e that is inserted into the central portion of the coil spring 33 is formed in the spring attachment portion 32d. The ball discharge operation lever 32 is attached so that the handle portion 32 b protrudes from the front surface of the side cover 31. Thus, the player can operate the ball discharge operation lever 32 with the handle portion 32b.

  The ball discharge operation lever 32 is moved to the holding position by rotating the link lever 23 clockwise from the holding release position and the reference position (see FIG. 5A) as the initial position for positioning the link lever 23 in the holding release position. It is attached to the side cover 31 so as to be slidable between the operation position to be positioned (see FIG. 5B). The ball discharge operation lever 32 is urged from the operation position toward the reference position (initial position) by a coil spring (operation urging means) 33. The coil spring 33 is inserted into the spring insertion shaft 32e of the spring attachment portion 32d, the left end is attached to a spring fixing portion (not shown) inside the side cover 31, and the right end is attached to the spring attachment portion 32d. Yes. When the ball discharge operation lever 32 is moved from the reference position to the operation position, the link lever 23 rotates clockwise (from the holding release position toward the holding position).

  The operation of the pachinko machine 2 configured as described above will be described. When a player plays a game with the pachinko machine 2 and wins a jackpot, the attacker 14 opens and the pachinko ball 7 enters the attacker 14. The pachinko ball 7 that has entered the inside of the attacker 14 enters the special winning opening 18 and is detected by the special winning ball detection sensor. When the pachinko ball 7 is detected by the big winning ball detection sensor, a predetermined amount of the pachinko ball 7 is paid out to the supply tray 6 through the receiving opening 6c.

  Since only 200 pachinko balls 7 can be stored in the supply tray 6, when more pachinko balls 7 are paid out to the supply tray 6, the player places the pachinko balls 7 outside the pachinko machine 2. It is necessary to discharge to the placed ball storage box. In this case, the player moves the ball discharge operation lever 32 from the reference position (see FIG. 5A) to the operation position (see FIG. 5B). When the ball discharge operation lever 32 is moved to the operation position, the link lever 23 rotates from the holding release position (see FIG. 5A) to the holding position (see FIG. 5B), and the link lever 23 is pushed. It is held by the locking device 24. As a result, the link lever 23 is positioned at the holding position even after the player releases his hand from the ball discharge operation lever 32. When the player releases his hand from the ball discharge operation lever 32, the ball discharge operation lever 32 moves from the operation position to the reference position by the bias of the coil spring 33.

  When the link lever 23 rotates from the holding release position to the holding position, the shutter 22 rotates from the shielding position (see FIG. 5A) to the open position (see FIG. 5B). Since the link lever 23 is held at the holding position by the push lock device 24, the shutter 22 is held at the open position by the link lever 23 held at the holding position. When the shutter 22 rotates to the open position, the pachinko balls 7 stored in the supply tray 6 are discharged to a ball housing box disposed outside the pachinko machine 2 through the discharge opening 6b and the base opening 21b.

  After the big hit, it is necessary to shield the discharge opening 6b. In this case, the player moves the ball discharge operation lever 32 from the reference position to the operation position. When the ball discharge operation lever 32 is moved to the operation position, the link lever 23 rotates clockwise from the holding position, and the holding of the link lever 23 by the push lock device 24 is released. When the holding of the link lever 23 is released, the shutter 22 rotates from the open position to the shield position by the bias of the torsion spring 25. When the shutter 22 rotates to the shielding position, the discharge opening 6b is shielded by the shutter 22. When the shutter 22 rotates from the open position to the shielding position, the link lever 23 rotates from the holding position to the holding release position.

  As described above, when the player moves the ball discharge operation lever 32 from the reference position to the operation position, the link lever 23 is held at the holding position by the push lock device 24 even after the hand is released from the ball discharge operation lever 32. Since the shutter 22 can be held in the open position by the link lever 23 held in the holding position, when the pachinko ball 7 stored in the supply tray 6 is discharged, the ball discharge operation lever 32 is operated. There is no need to continue, and operability can be improved.

  Further, when rotating the shutter 22 from the open position to the shielding position, it can be performed simply by moving the ball discharge operation lever 32 from the reference position to the operation position, so that the operability can be improved.

  Further, the side cover 31 for exposing and shielding the ball launcher is provided on the left side of the supply tray 6, and the ball discharge operation lever 32 is attached to the side cover 31. Since it is disposed at a distant position, it is possible to reduce erroneous operation of the ball discharge operation lever 32, and moreover, compared to the supply tray 6 provided with the ball discharge operation lever 32, the installation space of the supply tray 6 is reduced. Can be taken widely.

  In addition, since the coil spring 33 that biases the ball discharge operation lever 32 toward the reference position that contacts the second arm portion (one end) 23c of the link lever 23 is provided, when the ball discharge operation lever 32 is not operated, The ball discharge operation lever 32 can be positioned at the reference position.

  In the above-described embodiment, the shutter 22 is attached to the shutter shaft portion 21c of the base plate 21 so as to be rotatable between the shield position and the open position. It is only necessary to be able to be displaced between the shielding position and the open position according to the rotation of the lever 23, and the shutter 22 is attached to the base plate 21 so as to be movable left and right or up and down between the shielding position and the open position. You may do it.

  In the above embodiment, the link lever 23 is attached to the link shaft portion 21d of the base plate 21 so as to be rotatable between the holding position and the holding release position. However, the link lever 23 is not limited to this. Can be displaced between the holding position and the holding release position in accordance with the movement of the ball discharge operation lever 32, and the link lever 23 is moved left and right or up and down between the holding position and the holding release position. The base plate 21 may be attached as possible.

  Further, in the above embodiment, the link lever 23 and the shutter 22 are rotated by moving the ball discharge operation lever 32 in the left-right direction. However, the present invention is not limited to this, and for example, the ball discharge operation lever 32 is rotated. The link lever 23 and the shutter 22 may be rotated by rotation of the ball discharge operation lever 32.
