Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a winning device installed on the game board surface of a pachinko machine.

[Prior Art] Many proposals regarding winning devices for pachinko machines have already been made and put into practical use. The basic form of a winning device is a fixed winning device that has a hole larger than the diameter of a pachinko ball, but current winning devices set conditions and when the conditions are met, widen the hole to make it easier to win. Movable prize-winning devices that narrow or close the entry opening to make it difficult to win have become widely used and put into practical use.

Some movable winning devices use the weight of the flying ball (winning ball) to open and close the flying hole by rotating wing pieces near the flying hole, but this makes it possible to win many prizes in a given time. There is a so-called big winning device that uses a solenoid as a driving force.

This winning device is usually equipped with wing pieces that rotate to the left and right of the jump entrance, and when a winning command is received, a solenoid is excited to rotate and open the wing pieces, allowing the ball to fly in. The opened wing pieces pick up the ball and guide it in,
It is designed to greatly increase the winning efficiency.

[Problems to be solved by the invention] The above-mentioned conventional prize-winning device catches the batted ball when winning a prize by opening the wing pieces provided at the entry port, which greatly improves the winning efficiency. Since it is necessary to provide space on the left and right sides of the entry hole for the winnings to be played, the surface of the game board is restricted by this, and it may be difficult to install other winning devices.
In addition, when the wing is opened, the wings open in a substantially horizontal position and wait for the ball to be hit, so once the ball is hit, it sometimes falls off and does not win a prize.

This invention was developed in order to improve upon the problems of conventional winning devices, especially those that operate the winning opening and change the entry conditions by opening and closing the wing pieces. This minimizes the space occupied on the game board surface when a prize can be won to avoid hindrance to other winning devices, and also prevents the winning ball from escaping once it has landed, making it possible to catch the ball reliably. Therefore, we would like to propose a winning device that makes it possible to win a prize with certainty.

[Means for Solving the Problems] That is, the present invention was made based on the above-mentioned purpose, and its features include a mounting board having an entrance/exit window fixed to the game board; It has a ball catching frame that faces the window from the rear and is slidably housed in the window, and a driving means that slides the ball catching frame back and forth through the entrance/exit window, and when catching a ball, the driving means moves the ball catching frame. protrude forward through the doorway,
This is a winning device for a pachinko machine that is retracted to the rear of the entrance/exit window when the ball is not being caught.

[Function] The device of the present invention operates the driving means when receiving an opening command as in the conventional prize-winning device, and moves the ball catching frame into a state where it can catch a ball, that is, slides forward to close the entrance/exit window of the mounting board. The ball-catching frame is made to protrude from the front surface of the game board, making it possible to catch balls that fall along the board surface, while at the same time, during the cold season, the ball-catching frame is moved back and placed inside the entrance/exit window, making it impossible to catch balls. It is.

Examples illustrating the present invention will be described below.
Its features will be explained in detail.

[Example] Figure 1 is a partially cutaway front view of the winning device of the present invention, Figure 2 is a partially cutaway plan view of the winning device in use, and Figure 3 is a right side view of the main part in cross section. It is a diagram.

In the drawing, 1 is a mounting board for fixing to the game board 2, 3 is an entrance/exit window opened on the mounting board,
4 is a box-shaped frame provided so as to protrude rearward along the edge of the entrance/exit window 3; 5 is a capture frame housed inside this frame and facing the entrance/exit window 3 from behind;
6 is a solenoid for driving the capture frame.

The catching frame 5 is formed into a rectangular dish shape and has a depth sufficient to receive pachinko balls.
The front plate 7 is tilted forward to avoid facing parallel to the glass plate 8, and the bottom is open to accommodate the received batted balls (winning balls) in a safe ball gathering room (not shown) located behind the game board 2. It is designed so that it can be guided to

This capture frame 5 is provided with protrusions 9, 9 having lengths in the front and rear direction on the outer surfaces of the left and right side plates, and these protrusions are connected to the frame body 4.
slidingly fitted into guide grooves 10 provided on the inner surfaces of both side walls,
It is housed so that it can be slid in the front and back direction using this groove as a guide. The protrusions 9, 9 are hollow inside as shown in FIG.
1 and receives the end of the connecting frame 12 inserted from the rear.

The connecting frame 12 transmits the drive of the solenoid 6 to the capture frame 5, and is connected to the end of an interlocking frame 14 fixed to the plunger 13, and when the plunger 13 moves forward by energizing the solenoid 6, It moves forward and projects the capture frame 5 to the front of the mounting board 1 through the entrance/exit window 3.

This connecting frame has an end pushed into the hollow interior of the protrusion, which is pressed backward by a compressed spring 11, and a collar 15 provided at this end is brought into contact with the rear wall of the hollow interior. . Therefore, the connection frame 1 in the normal state
2 is adapted to move the catching frame 5 forward and backward with the collar 15 in contact with the rear wall and extending rearward. Note that the pressing of the connecting frame by the spring 11 is a means to prevent damage to the glass plate 8 and damage to the device due to balls getting caught when the catching frame moves forward, and the catching frame 5 moves forward by energizing the solenoid. At this time, when a ball is caught between the front plate 7 and the glass plate 8, the compression of the spring 11 absorbs the pinching of the ball and promotes the ball to fall.

In the figure, reference numeral 16 indicates a pivot portion 1 at both ends of the upper edge of the entrance/exit window 3.
This is an auxiliary door that is swingably hung with a

As shown in an enlarged view in FIG. 4, this auxiliary door has a weight 18 embedded in its lower edge so that it is suspended by its weight.
A coil spring 19 is contracted at 7 so that the door automatically returns when the lower end of the door swings backward.

This auxiliary door 16 is intended to prevent a batted ball from being caught between the front plate 7 and the upper edge of the entrance/exit window 3 when the trapping frame 5 retreats, and is always kept in a hanging state. This will prevent the ball from flying into the air,
In addition, the interior of the frame 4 is prevented from being exposed. When the ball tries to enter the front plate 7 by riding on it, it is brushed off, and depending on the timing, when the ball enters through the entrance window while riding on the upper edge, the door is swung backwards to allow it to pass. This is intended to prevent biting.

Further, numeral 20 in the figure is a distribution section provided on the left and right sides of the entrance/exit window 3. This distribution section 20 is attached to the mounting board 1
The upper surfaces 21 are inclined downwardly inward to make it easier for fallen balls to fly into the catching frame 5 along this slope. There is.

The prize-winning device of the present invention is constructed as described above, and in the normal state, the solenoid 6 is demagnetized and the capture frame 5 is pushed backward by the bias of the spring 22 which is wound around the plunger 13 and compressed. It will retreat from the entrance/exit window 3 and fit inside the frame.

In this state, when a ball enters another winning hole provided on the game board 2, a signal is generated under this condition, and when the solenoid 6 is energized to open, the ball flies against the bias of the spring 22. Plunger 13 moves forward,
The catching frame 5 projects through the connecting frame 12 to the front surface of the mounting board 1 through the entrance/exit window 3, and can catch a batted ball. If a ball falls during the forward movement of this catching frame, there is a risk that the ball will be caught between the front plate 7 and the glass plate 8. However, in this embodiment, as described above, the slope of the front plate 7 This danger is avoided.

The ball is then sent to the ball sorting section 2.
It protrudes between the play area and the play area 10, and in addition to directly catching balls that fall along the play board and making them winning balls, it also receives and catches balls that fall onto this distribution area.
Of course, it goes without saying that the distribution part itself does not necessarily guide the ball only toward the catcher's frame.

The batted balls caught by the catching frame 5 are guided to the safe ball collection chamber through the opening at the bottom, but a counting detection switch is provided in this process to count the total number of incoming balls, and to detect a predetermined number of incoming balls. Operations such as demagnetizing the solenoid and retracting the capture frame 5 at the time of detection may be designed in accordance with those in conventional winning machines of this type.

In the embodiment, two means, the weight 18 and the coiled spring 19, are employed to maintain the hanging state of the auxiliary door 16, but it goes without saying that only one of them may be used.

[Effects of the invention] The device of the present invention operates in accordance with the structure as explained above, and when catching a ball by advancing the catching frame, it goes straight to the front of the game board and becomes ready to catch the ball, which prevents it from falling. In addition to being able to reliably catch the ball that is being hit, the ball does not spread beyond the installation range of the device, for example, to the left or right when it is possible to catch the ball, so it does not interfere with the installation of other devices on the game board. It's advantageous.

In addition, the prize-winning device according to the present invention can be combined with the distribution section to change the winning rate when the ball can be caught, making it possible to make the prize-winning device even more interesting.
