BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winning device incorporated in a game board of a pachinko machine.

[0002]

2. Description of the Related Art There have been various types of proposals relating to winning devices, and there are many practical examples. The present invention relates to an improvement of a winning device in which a prize path that jumps into a lot of conventionally proposed devices is changed by a derivative provided in the device to change the value of the winning ball. And, more specifically, it relates to improvement of the driving means for moving the above-mentioned derivative up and down. In general, the winning ball derivative of the winning device is usually designed to reciprocate by the movement of the solenoid sliding the plunger and the movement of rotating the crank by the rotation of the motor. It cannot be adopted in a winning device that changes the winning condition by changing the state over time because of the movement of the moment. On the other hand, the movement of the motor can be freely selected by adjusting the rotation of the motor, the size of the crank, the gear ratio to be inserted, etc., so it is often used in devices that change the winning conditions with time. Has been adopted. However, when an attempt is made to reciprocate an object, such as a derivative, which moves with time and changes winning conditions, for example, by using a crank mechanism, it becomes slower at the reciprocating point and becomes faster at the middle and becomes uniform speed. There is a problem that cannot be obtained. Further, according to this crank mechanism, there is a problem in that there is a difference in speed during movement and at the same time rattling occurs, which impairs the accuracy of the device. Further, since the crank mechanism requires a space for accommodating the rotating arm, a mounting space must be prepared when incorporating the device into the device, which causes a problem of hindering downsizing of the winning device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of the present invention. FIG. 1 is a front view of the winning device according to the present invention, which is partially sectioned, and FIG. 2 is a sectional view taken along line AA of FIG. Is a right side view, and reference numeral 1 in the drawing is a mounting board fixed along the front surface of a game board (not shown), 2 is a launching port opened in the central portion of the mounting board, and 3 is integrally formed on the back surface of the mounting board. A housing provided so as to block the back of the attachment opening 2 is a guide for a winning ball housed inside the housing.

The mounting board 1 has barriers 5 and 6 on the upper side and both sides on the front surface surrounding the entrance 2, and a winning hole 7 is provided on the upper barrier 5. The left and right barriers 6, 6 are provided to face each other, and a deficiency portion provided between the upper end of the barriers 6 and the upper barrier 5 is defined as a winning opening 8, and both winning openings open and close with a rotating shaft 9 as a fulcrum. A piece 10 is provided. In the front of the center of the entrance, a receiving plate 11 whose upper surface is inclined rearward so as to traverse is provided.

Although not shown, the airfoil piece 10 is opened and closed via a crank mechanism by excitation of a solenoid connected to the rear end of the rotary shaft 9, and when the solenoid is excited by a constant release command, the left side of FIG. Like the winged piece of Fig. 1, it falls down horizontally to open the winning opening 8, and when it is demagnetized, it turns to a standing posture like the winged piece on the right side of Fig. 1 and closes the winning opening. The airfoil piece 10 is inclined slightly inward when it is opened so as to guide a ball falling on the piece inward, and the upper surface of the piece at this time is made higher than the receiving plate 11 to guide the ball. The spheres are designed to fall naturally on the top surface of the receiving plate.

The housing 3 is received at the entrance 2 to open the front surface,
Behind the back plate 12 that closes the back surface, various mechanisms for operating the dielectric 4 are provided. The derivative 4 shown in this embodiment is formed into a doll body, and receives the winning ball B with the arm 4a protruding forward, and three winning balls B are provided side by side on the front edge of the bottom of the casing by the movement of the arm. , 14 can be selectively dropped.

The dielectric member 4 is provided with a substrate 15 on the back surface of the body portion 4b, a bearing member 17 is fixed through a window 16 formed in the back plate 12, and the bearing member is slid on a vertically provided spiral shaft 18 to stand up. It is supported in a closed state.

The spiral shaft 18 is rotatably supported by the upper plate 19 horizontally provided behind the back plate 12 having an upper end penetratingly supported and a lower end supported by a bearing 21 provided on the lower plate 20. Forward / reverse rotation motor 22 provided on the upper surface of the
It is designed to be driven to rotate by connecting the upper end of the shaft to. The spiral shaft 18 has a spiral groove 23 formed on the peripheral surface thereof, while the bearing member 17 is provided with a protrusion that slides in the groove so that the bearing shaft 17 slides up and down as the spiral shaft 18 rotates.
The derivative 4 can be moved up and down.

As described above, the dielectric body 4 has a body portion 4b which moves up and down together with the bearing member 17, and a leg portion 4c having a shaft 25 as a fulcrum at the lower portion of the body portion 4c, which is also capable of bending the knee. The legs 4d for receiving the ball B are provided at the lower ends of the legs.

This derivative moves the body 4b up and down in accordance with the rotation of the spiral shaft 18, and also bends and extends the legs 4c. At the same time, when the body descends, the swing rod 27 which projects rearward of the arm 4a. The tip of the arm is tilted downward by this, and when it rises, it is kept horizontal so that the ball B can be caught.

The oscillating rod 27 projects rearward from the rear end of the arm 4a through the window 16 and a spring 28 stretched between the rear end of the arm 4a and the bearing member 17 keeps the flap 4a in a horizontal position. I am urged. FIG. 2 shows a state in which the body portion 4b is at the highest position due to the rise of the bearing member 17 and the legs 4c are slightly bent.
At the same time as stopping the rise of the inductor 4 by contacting it with the upper edge of the arm 6, the arm 4a is kept in a horizontal position so that the ball from the front receiving plate 11 can be received between the left and right arms. In this state, the rotation of the spiral shaft 18 lowers the bearing member 17 and lowers the body portion 4b.
a will descend horizontally and hold the ball.

FIG. 3 shows the above-mentioned state, and when the body portion 4b is further lowered from this state, the pin 27a at the rear end portion of the swing rod 27 connects the upper plate 19 and the lower plate 20 to the left and right. Since the descent is impeded by a ridge 30 provided on the inner surface of the side plate 29, the swing rod 27 swings around the shaft 24 as a fulcrum, tilts the arm 4a forward and downward, and catches a ball. The ball B will be dropped.

FIG. 4 shows the tilted state of the arm 4a.
The ball B dropped from the arm falls on the foot 4d and is held again on the foot 4d. After the inductor 4 reaches the lowest point, the motor 22 is actuated by the sensor S2 (not shown).
By rotating it in the reverse direction and returning it to the raised position again.
The rear end of the swing rod 27 is released from 0, and the arm 4a is returned to the horizontal posture. Then, when the maximum rising point is reached, the sensor S1 is actuated again to return the motor 22 to the normal rotation to convert it to the downward rotation, and by repeating this, the dielectric 4 is moved up and down.

The foot 4d that receives the falling of the winning ball B is connected to the plunger 32 of the solenoid 31, and the ball falling by lowering the toe with the solenoid which is normally in the demagnetized state is located in the center as it is. 13 (see FIG. 5). Then, the solenoid 31 is driven by a signal from the outside.
When the magnet is excited, the plunger 32 is pushed forward and the tip of the toe is raised to catch the falling ball.

Therefore, the ball B that has jumped into the inside of the housing through the entrance 2 and is held by the arm 4a of the dielectric is held between both arms until the dielectric 4 descends to a fixed position, and after the swing rod 27. When the end hits the ridge 30, it falls from the arm and is guided to the lower leg 4d. And at this time, foot 4d
When the tip of the toe is in the lowered state, it directly enters the winning path 13 at the center of the front, and when the tip of the toe is raised by the excitation of the solenoid 31, the ball B is held on the foot and is prevented from moving into the winning path. Then, in this state, when the next ball is released from the arm 4a, the ball collides with the previous ball, is repelled to the left and right, and is distributed to the left and right winning paths 14.

In the figure, 33 is a solenoid for tilting the left and right arms 4a in the horizontal position to one side to drop a ball B held by the arm 4a sideways, and 34 is attached to a plunger 35 of the solenoid and is a swing rod. It is a projecting member formed in a bifurcated shape in which 4a is tilted forward and downward by being inserted under the rear end portion of 27.

The projecting member 34 slides back and forth by sliding both edges into a groove 36 parallel to the upper surface of the projection 30 provided along the inner surface of the side plate 29, and normally the solenoid 33 is demagnetized.
As the plunger 35 is pushed out by the spring 37, it moves forward so that the tip end abutting portion 34a is exposed below the pin 27a provided at the rear end portion of the swing rod 27. Therefore, the oscillating rod 27, in which the inductor 4 is in the raised position and supported horizontally by the tension of the spring 28, descends in a state in which the left and right objects are horizontally aligned until the inductor 4 is in the middle of lowering. Just before reaching the contact point, the pin 27a at the rear end of one of the swinging rods has the above-mentioned abutting portion 3
4a, the one arm 4a is tilted forward and downward with the shaft 24 as a fulcrum, so that the horizontal state collapses and the ball B supported by the left and right arms falls to the tilted side, and the gutter 38 provided immediately below it. Will be transferred to the winning path 14 in the front.

On the other hand, when the solenoid 33 is excited by a signal from the outside and the projecting member 34 is retracted by retracting the plunger and the guide member 4 is lowered, the swing rods 27 of the left and right arms 4a are both in a horizontal state. While keeping the same, the rear end of the ball collides against the ridge 30 at the same time, and in a parallel state, the ball received by the arm is forwardly forwarded and dropped on the foot 4d while leaning forward. The ball that has fallen on this foot is in the central or left and right winning paths 13,1 through the above-mentioned process.
Will be guided to 4.

The device of the present invention is constructed as described above, and by inserting the housing 3 from the front side into the mounting hole formed in the central portion of the game board, the mounting board 1 is brought into contact with the game board and screwed. It is installed. When the wing-shaped piece 10 is open, the hit ball enters through the winning opening 8 and is received by the receiving plate 11,
From this receiving plate, it will move in toward the rear derivative 4. Of course, the ball that jumps in may enter the inside of the housing directly,
The ball that jumps in is the winning path 13, 1 on the bottom as it is.
You will be in 4.

The derivative 4 is a motor 22 that repeats forward and reverse rotations.
Move up and down. Then, in the middle of the vertical movement, the left and right arms 4a protruding horizontally forward are tilted to the front descent state, and the ball 4 received from the receiving plate faces directly below the front side.
It drops to d and guides to the winning path 13 in the center through this foot. On the other hand, as described above, one of the arms is tilted and dropped into the lateral gutter 38 to guide it to the winning path 14, or the toes of the foot 4d are raised to catch and hold the falling ball and to hit the subsequent falling ball. Skein prevents the transfer to the winning path 13 in the central part.

In such an operation, the inductor 4 moves up and down in accordance with the rotation of the spiral shaft 18 caused by the rotation of the forward / reverse rotation motor 22, but in this embodiment, the spiral shaft 18 makes one rotation with respect to the range of vertical movement. As a result, the spiral groove 23 is formed with a large pitch so that the bearing member 17 can be moved from the raised position to the lowered position and from the lowered position to the raised position. Of course, the spiral shaft 18 is not limited to make one rotation with respect to the vertical movement of the inductor, and may be two or three rotations, but the rotation speed can be made small, which imposes a burden on the motor. Is advantageous because it can be made small and quick vertical movement can be set.

[0024]

As described above, the present invention has been described in detail with reference to the illustrated embodiments. According to the present invention, the vertical movement of the winning ball derivative provided inside the housing is accompanied by the rotation of the spiral shaft vertically supported. Since the bearing member is moved up and down, the speed at the time of starting does not change and it can be moved at a uniform speed at all times, and stable up and down movement can be obtained. On the other hand, since the bearing member slides by sliding the projections in the spiral groove formed on its peripheral surface, there is no rattling like in the case of straight movement through the crank mechanism, and it is smooth. Has the advantage of working. Further, since the device of the present invention rotatably supports the spiral shaft, and has a structure in which a bearing member is slidably engaged with this shaft to move the derivative along the shaft, there is no need to provide a space for rotation of the crank, Therefore, there is an advantage that the device can be designed compactly. Further, the spiral shaft of the present invention can freely set the pitch of the groove formed on the circumferential surface, and the moving speed of the bearing member can be arbitrarily set by setting the pitch, thereby providing a winning device with a change. can do.
