A detection switch 31 is provided at the special prize opening 30a. It is equipped. The detection switch 31 of the special winning opening 30a is a switch for continuously opening the entrances 9 and 9a. Therefore, it is advantageous for the player that the winning ball dropped through the drop opening of the distribution plate enters the special winning opening 30a. It will be The rail arm 11 serves as a guiding means for surely guiding the ball dropped through the central drop port 28b among the three drop ports of the distribution plate 27 to the special winning port 30a. The rail arm 11 is composed of a pair of left and right arms that are parallel to each other in the front-rear direction. Each arm is supported by the swing arm 12, and the spindle 32 of the swing arm rotates to maintain the parallel state.ゝ It is designed to move in and out. The support shaft 32 is a bearing 33 provided on the back plate of the box frame 8.
To the rear through the link 3
4 is attached to the shaft. Each of the links 34 has the other end connected to a leg end of an interlocking member 35 forming two forks via a pin 36. The interlocking member 35 is rotated by a motor 38 via a connecting rod 37. Connected to. The interlocking member 35 includes a vertical sliding plate 40 and a box frame 8
Is vertically slid to a guide 41 provided on the back surface of the connecting rod 37, and a pin 42 provided on the sliding plate 40 is fitted with a hole 43 of the connecting rod 37, and a pin 44 of the rotating body 39 is connected to the connecting rod. The other hole 45 is fitted to be connected. In the figure, reference numeral 46 is a limit switch for controlling the rotation of the motor 38, and the motor 38 starts driving together with opening the door piece 10 when a hit ball hits the specific winning opening 4. This motor 38 is driven to rotate the rotating body 39.
When is rotated, the connecting rod slidingly engaged with the pin 44 acts as a crank to vertically move the bifurcated interlocking member 35, and the vertical movement of the interlocking member 35 causes the link 3 pivotally attached to the support shaft 32.
4 swings up and down to rotate the support shaft 32 forward and backward. The swing arm 12 pivotally attached to the support shaft swings with the rotation of the support shaft, and the rail arms 11 projecting forward in parallel are moved in the left-right direction to keep the distance between the two. It will be opened and closed. The two parallel rail arms 11 are formed on the upper surface of the guide piece 4 which is inclined forward along the length direction.
7, the two swinging arms 12 are provided along with the pulling up of the interlocking member 35 when the pin 44 of the rotating body 39 reaches the uppermost point.
Are drawn inward, and the interval between the guide pieces 47 is narrower than the size of the pachinko ball to form a guide path. In this state, when there is a winning ball falling from the drop opening 28b, it is received and guided to the special winning opening 30a provided on the bottom plate 29 without fail. The opening / closing movement of the rail arm 11 is performed by driving the motor 38 as described above, and this opening / closing movement is continuously performed so as to reverse the opening / closing movement due to the assembly of the game, or in the closed state. Alternatively, the state of being opened to the left and right may be continued for a certain period of time, which will be arbitrarily selected. The prize winning device of the present invention is constructed as described above, and in the normal state, the solenoids 18 and 23 are demagnetized, so that the door pieces 1 are operated by the springs 21 and 26.
0, the obstacle plate 13 closes the respective entrances 9 and 9a. When the hit ball enters the specific winning opening 4 in this state, the switch 22 detects the winning ball and excites the solenoids 18 and 23 to open the entrance. Excitation of the solenoid associated with this detection is arbitrarily selected by setting the game, and by maintaining a timer for a certain period of time to maintain a high winning probability, or there is a preset number of winning balls. When it is demagnetized, it is set arbitrarily. The winning balls that have entered through the entrances 9 and 9a are dropped through openings 28a and 28 provided in the distribution plate 27.
It falls from either b or 28c. Of these, the one dropped from the central drop port 28b falls onto the guide piece 47 of this rail when the left and right rail arms 11 provided in the space below it fall close to the center at the time of this fall. The member rolls forward and is guided to the special winning opening 30a below. Then, the left and right drop ports 28
Those dropped from a and 28c roll forward according to the inclination of the bottom plate 29, and the special winning opening 30a or the normal winning opening 30
It moves into any of b and is transferred to the winning ball processing device provided on the back surface of the game board 1 through the passage 48. When the rail arm 11 is open to the left and right, the ball dropped from the central drop port 28b falls on the distribution table 49 provided on the upper surface of the bottom plate, is distributed to the left and right, and the momentum of the drop causes the box frame to move. When it collides with the side surface, it will roll on the bottom plate 29 toward the front special winning opening or the normal winning opening. By the way, in the prize winning device of the present invention, the door piece 10 for closing the entrance 9 is provided at the tip of the rotary arm 17 which is rotated by the rotation of the support shaft 16, and is arcuate when the rotary arm is rotated during opening and closing. By opening and closing, it is possible to open and close the entrance 9 with a small movement. In particular, in the case of the embodiment, the entrance can be opened and closed by rotation of 45 degrees, which enables quick operation. Further, since this door piece opens and closes along an arc, it does not hit like a conventional wing piece door piece, and therefore can be opened and closed smoothly without hitting a hit ball. On the other hand, the obstacle plate 13 for closing the central entrance 9a in the embodiment may be opened and closed in parallel with the opening and closing of the door piece 10, but may be opened and closed at different times. In particular, since the entrance 9a is located in the central portion and above the drop opening 28b provided in the central portion of the distribution plate 27, it is opened when the rail arm 11 leans close to the central portion to form the guideway. May be set as follows. On the other hand, inside the box frame, the special winning opening 3
As described above, the rail arm 11 forming the guide path connecting the 0a and the fall port 28b of the distribution plate is driven by the motor 38 due to the hitting of the ball into the specific winning port 4, whereby the left and right arms are parallel to each other. While keeping the state, it opens and closes and forms and releases the guideway, but the opening and closing of this rail arm is interlocked with the opening of the entrance 9 or the entrance 9a,
The opening / closing motion may be continued while it is open, the opening / closing motion may be intermittently continued, or the rail arm may be closed to form the guide path continuously. It can be optional. Further, since the opening and closing movement of the rail arm 11 has an important effect on guiding the winning ball to the special winning opening 30a, the rail arm is always moved when the entrances 9 and 9a are closed. Whether the device is closed to keep the guideway formed or conversely opened to release the guideway changes the game characteristic of the device, but the setting is made to face the rotating body 39. The limit position can be arbitrarily determined by selecting the stop position of the motor 38 with the limit switch 46. Of course, in this case, the entrance 9, 9a
It is also possible to stop the driving of the motor 38 along with the closing of the rail arm 11 to stop the rail arm 11 in the middle of the movement, and to start the movement from this stop position when the entrances 9 and 9a are next opened. Needless to say. The prize winning device of the present invention is constructed as described in detail in the above embodiment, and the obstacle plate which is provided so as to freely project and retract facing the entrance opens and closes the entrance through the retracting operation. , This obstacle plate is provided at the upper part of the entrance of the prize winning device, and when the hit ball falling from directly above is made a straight prize ball when it is opened, it is distributed to the left and right when it is closed, so it is not in this type of conventional prize device You can enjoy the ball hitting straight. In particular, in a prize winning device equipped with a special prize opening for continuing the opening of the door piece inside the prize winning device and a normal prize opening for simply counting the number of incoming balls, by installing it just above this special prize opening Since it is possible to increase the probability of jumping into the special winning opening straight and the player can directly see this, it is possible to provide a more varied winning device. On the other hand, the door piece provided at the entrance is provided at the tip of the rotating arm and opens and closes in an arc shape. At this time, the entrance can be opened and closed in a small movement without being disturbed by the support shaft. The door can be opened and closed promptly, and the door can be opened and closed smoothly without hitting the ball because the door does not hit like a conventional door of this kind when opening and closing. In addition, since this door piece is formed in an arcuate cross section and opens and closes in an arcuate shape, the ball received on the door during opening and closing can be guided to the entrance when opening and to the outside when closing without opening the ball. There is an advantage that can be processed.
