Description

  The present invention relates to an improvement of a large winning device for a pachinko machine.

  2. Description of the Related Art As a big prize device disposed on a game board of a pachinko machine, an apparatus having an opening / closing door that is normally maintained in a closed state is known. In the one disclosed in Patent Document 1, the standing door is pivoted forward to open the big prize opening, and the ball is received on the back surface of the pivoted door to guide the ball into the winning device. Can do.

However, the large prize winning device provided with the opening and closing door as described above is common and scarcely changed, and lacks the interest of the game. In addition, when the open / close door is in a closed state, it has nothing to do with the contents of the game. In recent years, with the increase in the size of image display devices, there is a tendency to limit the installation space for other gaming parts occupying the entire gaming area. The vertical width of the open / close door when standing in the winning device is constant so that when the open / close door is opened, a ball bite does not occur between the glass plate provided in front of the game board and the upper end of the open / close door. This is necessary. Therefore, there is a limit that the winning device cannot be thinned below the vertical width of the open / close door at the time of standing. Furthermore, even if the open / close door is closed immediately after a predetermined number of balls have been won in the grand prize opening when the open / close door is opened, the ball that was present on the open / close door is introduced inside the open / close door and becomes a winning ball Will be treated. Therefore, there has been a problem that there is a possibility that a prize ball exceeding the set value may be paid out.
JP 2004-173811 A (FIG. 2)

  In view of the above-described conventional problems, the present invention has an object to provide a large winning device for a pachinko machine that can perform excitement of games and accurately pay out a ball and can be thinned. To do.

A large winning device for a pachinko machine according to the present invention made to solve the above-mentioned problems, a ball winning box is projected in front of a base plate for attaching the device main body to a game board, and the upper surface of this ball winning box And a shutter plate that opens and closes the grand prize opening by sliding horizontally on the big prize opening, and is inclined low toward the direction of the big prize opening on the upper surface of the shutter plate. A rail is provided, and a ball that has fallen on the rail is guided in the direction of the big prize opening to be awarded .

In addition, a lever operated by a solenoid is arranged in the apparatus main body, one end of this lever is connected to the shutter plate, and the other end is provided with a fork that engages with a solenoid plunger . during forward state of plunger and during retraction state, perpendicular to the sides of the head of the plunger can abut tip face can be provided, respectively.

  In the invention according to claim 1, since the big prize opening and the shutter board are provided on the upper surface of the ball prize box protruding in front of the base plate, the shutter board slides horizontally on the big prize opening to The big prize opening can be opened and closed. Therefore, it is possible to provide a large winning device having a novel structure that has not been conventionally available. In addition, since the opening / closing door does not fall down and stand up unlike the conventional case, the thickness of the large winning device can be made thinner than the vertical width of the opening / closing door.

Further, in the invention according to claim 1, since the rail of the shutter plate guides the ball to one side of the ball winning box when the big winning opening is closed, the shutter plate is provided in a starting area provided below one side of the big winning device, etc. It can act as a guide member to Further, when the grand prize opening is opened, the shutter plate expands the prize winning area to the big prize opening in the lateral direction, and an unprecedented effect can be obtained.
In the invention according to claim 2, since the external force applied to the bifurcated tip surface is orthogonal to the forward and backward direction of the plunger, the rotation of the lever is locked during the forward and backward movement of the plunger, and the shutter plate by the external force is locked. Forced opening and closing can be prevented.

Hereinafter, the present invention will be described based on embodiments.
1-4 is a figure which shows the big prize apparatus which concerns on this invention, Comprising: In the big prize apparatus, the big prize opening is a closed state. In the figure, 1 is an apparatus main body, and 2 is a base plate for attaching the apparatus main body 1 to a game board (not shown). The base plate 2 is provided with a ball winning box 3 that protrudes in front of the base plate 2, and a large winning opening 4 and a shutter plate 5 are provided on the upper surface of the ball winning box 3. The big winning opening 4 is provided close to one side of the upper surface of the ball winning box 3. In addition, the shutter plate 5 slides in a direction parallel to the base plate 2 in the horizontal direction on the winning prize opening 4 to open and close the winning prize opening 4.

  The ball winning box 3 includes a box main body 31 formed integrally with the housing 11 constituting the apparatus main body 1 and a seal plate 32 fitted into the front surface of the box main body 31.

  The shutter plate 5 is provided with a rail 6 which is inclined downwardly in the direction of the big prize opening 4 on the upper surface thereof, and guides the ball falling on the rail 6 in the direction of the big prize opening 4 while rectifying the ball. In the state where the big winning opening 4 is closed, the rail 6 drops the ball downward from one side of the ball winning box 3. If an impact absorbing material is used for the ball contact surface of the rail 6, the ball that has dropped on the rail 6 when the big prize opening 4 is opened can be surely won in the big prize opening 4. On the contrary, if an elastic member is used, since the ball | bowl which fell on the rail 6 jumps irregularly, the interest of a game can be raised.

  In the apparatus main body 1, a lever 8 is disposed that has one end engaged with a plunger 71 of the solenoid 7 and the other end engaged with a shaft 81 protruding from the back side of the shutter plate 5. The lever 8 rotates about the support shaft 82. A bifurcated 83 is provided at one end of the lever 8, and a head 71 a of the plunger 71 is inserted between the bifurcated 83 and both are engaged. Since the solenoid 7 is normally not energized and the plunger 71 protrudes from the solenoid 7 due to the repulsive force of the spring, the lever 8 is rotated in the direction of the big prize opening 4 as shown in FIG. As a result, the shutter plate 5 is slid in the direction of the big prize opening 4 and closes the big prize opening 4.

The lever 8 includes a lock mechanism that prevents the shutter plate 5 from being opened and closed by an external force. The locking mechanism will be described with reference to FIGS. FIG. 7 is a view for explaining the locking mechanism when the shutter plate 5 closes the special winning opening 4, and the outer peripheral surface of the head 71a of the plunger 71 in the forward state is the tip surface of one fork 83a. It is in contact with. In this state, when the shutter plate 5 is forcibly opened using a piano wire or the like from the outside, a force in the clockwise direction around the support shaft 82 acts, so that the front end surface of the fork 83a Exerts F1 force on the head 71a of the plunger 71. Since the tip end surface of the fork 83a is set at an angle so that the direction of the force applied by F1 is perpendicular to the forward / backward direction of the plunger 71, the plunger 71 is not pushed in. Therefore, since the lever 8 is locked so as not to rotate, it is possible to prevent the shutter plate 5 from being forcibly opened from the outside by this locking mechanism.

FIG. 8 is a view for explaining the locking mechanism when the shutter plate 5 opens the grand prize winning opening 4. The outer peripheral surface of the head 71a of the plunger 71 in the retracted state is the tip end surface of the other fork 83b. It is in contact with. In this state, when the shutter plate 5 is forcibly closed by some external force, a counterclockwise force centered on the support shaft 82 is applied, so that the tip surface of the fork 83b is the head of the plunger 71. F2 force is exerted on the portion 71a. Since the tip end surface of the fork 83b is set at an angle so that the direction of the force applied by F2 is perpendicular to the forward / backward direction of the plunger 71, the plunger 71 is not pushed in. Since the lever 8 is locked so as not to rotate, the shutter plate 5 can be prevented from being closed by this locking mechanism. Therefore, the player is not disadvantaged.

  A winning ball detecting device 9 for counting the winning balls is arranged at the big winning opening 4. The big winning opening 4 communicates with the ball passage 12 in the housing 11, and the ball that won the big winning opening 4 is made to win through the ball passage 12.

When the symbols of the image display device are aligned and the jackpot state is reached, the solenoid 7 is energized and the plunger 71 is sucked into the solenoid 7 as shown in FIG. As a result, the end portion on the solenoid 7 side of the lever 8 is rotated by the plunger 71, and the end portion on the shaft 81 side of the lever 8 is rotated in the opposite direction. As a result, since the shutter plate 5 is moved together with the shaft 81, the shutter plate 5 can open the special winning opening 4. In addition, since the shutter plate 5 slides in the direction to open the grand prize winning opening 4, a ball can be received by the shutter plate 5 and the upper surface of the ball winning box 3, so that the winning area is expanded in the horizontal direction. , Can increase the probability of winning a big prize.
Therefore, the big winning device of the present invention can achieve a remarkable effect that the player's sense of expectation when a big hit occurs can be raised as never before.
