A storage portion 29 for storing 28 is formed. A lower winning opening 14 is opened at the front end of the case 21 (the right end in FIGS. 3 and 4), and a door member 18 is disposed in front of the lower winning opening 14.

  Next, the door operation mechanism 28 will be described with reference to FIGS. 5 and 6, the door operation mechanism 28 is basically supported by a solenoid 31 having a plunger (sliding shaft) 30, an operation member 32 connected to the plunger 30, and a rotation member 32. It is comprised from the door member 18 which opens and closes the lower prize-winning opening | mouth 14 based on the cooperative action with the lever member 33 and the lever member 33. FIG.

  Here, as shown in FIG. 6B, a disc 30 </ b> A is fixed to the distal end of the plunger 30, and the disc 30 </ b> A is fitted to the base end portion 32 </ b> A of the operating member 32. A connecting groove 32E is formed. Thus, the plunger 30 and the operating member 32 are connected to each other by fitting the disc 30A into the connecting groove 32E. The actuating member 32 has a base end portion 32A and a plate-like portion 32B extending vertically from the base end portion 32A. Further, in the plate-like portion 32B, a longitudinal groove-like support groove 32C extending downward from the upper edge is formed, and a long hole 32D extending in the horizontal direction is formed below the support groove 32C.

  The lever member 33 is formed of a plate material having a substantially triangular shape, and the support pin 33A extends in the horizontal direction from one side surface (the back side in FIG. 5B, the front side in FIG. 6B) of the upper apex thereof. Further, sliding pins 33B are extended from both sides of the lower apex thereof. Further, a rod-shaped operating portion 33C is extended from the remaining vertex.

  Here, the support pin 33 </ b> A of the lever member 33 is rotatably supported in the support groove 32 </ b> C of the operation member 32. Further, among the sliding pins 33B, the sliding pins 33B formed on the same side as the support pins 33A are slidably inserted into the long holes 32D of the operating member 32. Note that the end of each sliding pin 33B is supported in the case 21 so that the lever member 33 can rotate.

The door member 18 includes a door 18A and side plate portions 18B and 18B extending from both sides of the door 18A in a diagonal direction (a diagonally lower left direction in FIG. 5B and a diagonally right direction in FIG. 6B). Has been. A decorative portion 18C is formed on the door portion 18A. A rotation shaft 18D extends from each side plate portion 18B, and each rotation shaft 18D is rotatably supported by a support portion 21C of the upper case 21A. Further, of each side plate portion 18B, one side plate portion 18B (left side plate portion in FIG. 5B) is provided with an engaging pin 18E extending in the horizontal direction adjacent to the rotation shaft 18D. As will be described later, the engagement pin 18E is engaged with and released from the operation portion 33C of the lever member 33. Further, the one side plate portion 18B is provided with a contact pin 18F which is provided apart from the engagement pin 18E and can contact the operating portion 33C.
In the door member 18 configured as described above, as is clear from FIGS. 5B and 6B, the center of gravity of the door member 18 has a door portion 18A rather than a line segment connecting the rotation shafts 18D. Therefore, the door member 18 rotates around the respective rotation shafts 18D by its own weight in a state where no regulating force is applied.

  As shown in FIGS. 5B and 6B, a coil spring 34 is attached to the plunger 30 of the solenoid 31 between the side surface of the solenoid 31 and the side surface of the base end portion 32A of the operating member 32. Has been. The coil spring 34 always urges the base end portion 32A of the operating member 32 in one direction (right in FIG. 5B, left in FIG. 6B).

Next, the operation of the door actuation mechanism 28 configured as described above will be described with reference to FIGS.
First, when the solenoid 31 is not energized, the operating member 32 is urged rightward in FIG. 7 by the urging force of the coil spring 34. As a result, the lever member 33 is urged to rotate in the clockwise direction in FIG. 7 around the sliding pin 33B by the cooperation of the support pin 33A and the support groove 32C, and the door is about to rotate downward by its own weight. It is in contact with the contact pin 18F of the member 18. In this state, the door member 18 is urged to rotate counterclockwise in FIG. 7 around the rotation shaft 18D, and as a result, the door member 18 is in the first state in which the lower winning opening 14 is closed. Is held in.

  Thereafter, when the game ball passes through the start gate 17 and the normal symbol display result is hit, the solenoid 31 is energized to open the lower winning opening 14 by rotating the door member 18 downward by its own weight. . When the solenoid 31 is energized, the plunger 30 is moved in the left direction in FIG. 7 against the urging force of the coil spring 34. At the same time, the actuating member 32 is also moved leftward in FIG.

  Accordingly, the lever member 33 is rotated counterclockwise around the slide pin 33B by the cooperation of the support pin 33A and the support groove 32C, and the operation portion 33C is also rotated counterclockwise. Go. At this time, the engagement pin 18E of the door member 18 moves upward while contacting the operating portion 33C by the weight of the door member 18, whereby the door member 18 is rotated around the rotation shaft 18D by the weight of the door member 18 in the clockwise direction. Rotated in the direction. As a result, the lower winning opening 14 is opened by the door member 18. Such a second state is shown in FIG. In this state where the door member 18 is rotated and the lower winning opening 14 is opened, the game ball is guided by the game ball guiding inclined surfaces 27 and 27 and the door member 18 to enter the lower winning opening 14. Pass through and be guided inside the pachinko gaming machine 1.

  As described above, in the central variable winning device A disposed on the game board 3 of the pachinko gaming machine 1 according to the present embodiment, when the solenoid 31 is not energized, the operating portion 33C of the lever member 33 and the door member 18 are engaged. A first state in which the lower winning opening 14 of the case 21 is closed via the door member 18 by prohibiting the downward rotation due to the weight of the door member 18 by the engagement with the joint pin 18E. 7), and when the solenoid 31 is energized, the door member 18 moves downward due to its own weight while the engagement between the operating portion 33C of the lever member 33 and the engagement pin 18E is released corresponding to the movement of the plunger 30. Is held in the second state in which the lower winning opening 14 of the case 21 is opened (FIG. 8).

  Thereby, according to the central variable prize-winning device A, the operation is based on adopting the door member 18 that rotates downward by its own weight without using a complicated coupling mechanism and without requiring a large solenoid. The door member 18 can be opened and closed with a simple configuration including the member 32 and the lever member 33.

  Further, when shifting from the second state to the first state, an operation opposite to the above-described operation is performed. During this time, the door member 18 gradually rotates in the direction of closing the lower winning opening 14. Even when the game ball falls on the door member 18, the door member 18 can be rotated downward by its own weight, and so-called “ball biting” does not occur between the game ball and the door member 18.

Furthermore, the door member 18 is not forcibly opened and closed using the driving force of the solenoid 31, but is configured to be able to rotate downward under its own weight. Depending on circumstances, the door member 18 may not be opened as described above.
In such a case, as shown in FIG. 9, the door member 18 is not rotated downward by its own weight, that is, the door member 18 is in a state of closing the lower winning opening 14 as in the first state. The lever member 33 is slightly rotated counterclockwise in FIG. 9 based on the leftward movement of the operating member 32. In this state, one of the contact pins 18F of the door member 18 is provided. The part exists inside the rotation locus K drawn by the tip of the operating part 33C of the lever member 33.

  As a result, the operating portion 33C of the lever member 33 comes into contact when the lever member 33 is slightly rotated counterclockwise based on the fact that the solenoid 31 is energized and the operating member 32 is moved slightly to the left. It will contact the pin 18F. Thereafter, the actuating member 32 is further moved to the left via the plunger 30, whereby the lever member 33 is further rotated to forcibly raise the contact pin 18F. As a result, the door member 18 is rotated in the clockwise direction to be in the second state shown in FIG.

  As described above, when the door member 18 does not rotate downward due to its own weight when the solenoid 31 is energized, the operating portion 33C of the lever member 33 and the contact pin 18F are brought into contact with each other via the lever member 33. Since the door member 18 is forcibly rotated downward and held in the second state, the door member 18 is forcibly opened even when the door member 18 is not opened due to some circumstances when the solenoid 31 is energized. It becomes possible.

In addition, this invention is not limited to the said embodiment, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention.
For example, in the above-described embodiment, the solenoid 31 is used as a drive source for opening and closing the door member 18, but the present invention is not limited thereto, and a motor or the like may be used.
In the above-described embodiment, when the door member 18 is normally opened, the door member 18 is also rotated following the rotation of the lever member 33, and the contact pin 18F is moved from the rotation locus K of the operating portion 33C. Since the operating portion 33C does not come into contact with the contact pin 18F of the door member 18, the operating portion 33C may be configured to contact the contact pin 18F.
Furthermore, in the said embodiment, although the door member 18 is comprised so that it may open and close in the front-back direction, the structure by which the door member 18 is opened and closed in the left-right direction may be sufficient.
