Description

  The present invention relates to an electric tulip that operates when a specific condition is satisfied, and a variable winning device and a pachinko gaming machine that can solve a problem that a mechanism for opening and closing a winning opening is illegally opened. .

Pachinko machines equipped with electric tulips are conventionally known. The electric tulip is composed of a pair of blades (movable pieces) that are rotated by using a solenoid as a drive source, and when a game ball wins a predetermined start winning opening, the solenoid is operated to turn the pair of blades once or two. By opening and closing about several times, the game ball flowing down the game board surface is captured and guided into the variable winning device.
A pachinko gaming machine has a rectangular frame, and a game board is detachably attached to a window hole of the frame. The game board surface is equipped with the above variable winning device. A glass frame is attached to the front side of the game board so that it can be opened and closed.
By the way, a fraudulent act has been conventionally performed in which a wire or the like is inserted from a gap formed between the glass frame and the game board to forcibly open the blades of the variable winning device to obtain a ball.
As a countermeasure for preventing such an illegal act, Patent Document 1 describes a variable of a type in which a blade is opened when a plunger is retracted while a blade is held in a closed position when the plunger of the solenoid is protruding. In the winning device, the blade is locked in the closed state when the plunger is protruding, while the unlocking of the blade is provided by providing a lock mechanism that releases the lock and allows the blade to open when the plunger is retracted. A technique for preventing the above is disclosed.
However, since this lock mechanism is provided at a position closest to the blade, the wire inserted from the gap between the glass frame and the game board is moved along the game board surface to reach the lock mechanism to lock. It was relatively easy to cancel.

JP 2008-272121 A

In the conventional variable winning device having a pair of blades that open and close as described above, a lock mechanism is provided in the vicinity of the blades, that is, on the surface side of the game board to prevent the blades from being illegally opened. Therefore, it has been relatively easy to release the locking means with a wire or the like inserted along the surface of the game board from the gap on the outer periphery of the gaming machine.
The present invention has been made in view of the above, and in a variable winning device provided with an opening / closing piece that opens and closes using a solenoid as a driving source, the variable winning device is located at a position deeper than the opening / closing piece and thus is not easily exposed to fraudulent acts.

FIG.

The variable winning device 12 according to the present invention is a means for opening and closing a winning opening formed on a board surface, and includes a pair of opening and closing pieces (blades) 30 and an opening and closing piece 30 as an example of an electric chew 14 that opens and closes the winning opening. An opening / closing mechanism 31 that opens and closes, a solenoid drive mechanism 40 that operates the opening / closing mechanism 31, and a lock mechanism 60 that locks the solenoid drive mechanism 40 are schematically configured.
The variable winning device 12 is disposed in an opening formed in the game board 3, and the pair of opening / closing pieces 30 are positioned in front of the game board surface, and the solenoid drive mechanism 40 is positioned in the rear of the game board. . The variable winning device 12 is fixed to the game board 3 by fixing the mounting member 35 shown in FIGS. 2 and 10 to the game board.
Each opening / closing piece (blade) 30 can be opened and closed in the left-right direction indicated by the arrow by pivotally supporting a shaft portion 30 a protruding from the lower rear surface by a pair of left and right shaft holes 35 a provided in the front portion of the mounting member 35. A projection-like actuated member 30b that is moved up and down by a solenoid-type drive mechanism 40 is provided on the back surface of the opening / closing piece inside each shaft portion 30a. The shaft hole 35a, the shaft portion 30a, and the actuated member 30b constitute an opening / closing mechanism 31 that opens and closes the opening / closing piece 30.

The solenoid-type drive mechanism 40 includes a coil 42 that switches between an energized state (energized state) and a non-excited state (non-energized state) when power is supplied from a power supply unit (not shown), and an elastic member (coil spring or the like) 43 when the coil is not excited. A pull-type solenoid 41 provided with a plunger 44 that protrudes forward while being energized by the coil and retracts backward when the coil is excited, a base member 45 that is fixed to the mounting member 35 and supports the solenoid 41, and a rear portion that is a base A pair of actuating arms 46 that actuate the opening / closing mechanism 31 and the opening / closing piece 30 by pivoting (turning) the tip portion in the vertical direction by being pivotally supported by the member 45, and actuating in conjunction with the retracting operation of the plunger 44. A connecting portion 47 that connects the plunger 44 and the operating arm 46 so as to swing the arm 46 is provided. The base member 45 constitutes a part of the attachment member 35. Further, the base member as a means for supporting the operating arm 46 is not necessarily integrated with the base member 45 for supporting the solenoid, and may be a separate member.
As is well known, the pull-type solenoid 41 is configured such that when a coil 42 wound around a fixed iron core is energized, the plunger 44 as a movable iron core is sucked and immersed, and is returned to the protruding direction by an elastic member 43 when not energized. Has been.

Each operating arm 46 is provided with a shaft support 46a extending in a direction (horizontal direction) orthogonal to the direction in which the plunger 44 protrudes and retracts (front-rear direction), and the shaft support 46a is provided on the base member 45 (or the mounting member 35). By being pivotally supported by a support portion (support hole), the opening / closing mechanism 31 is operated by swinging the tip portion in the vertical direction. Each operating arm 46 is integrated by a horizontal shaft 46c. FIG. 4B shows a procedure for assembling the operating arm to the solenoid drive mechanism 40.
Each operating arm 46 is provided with a substantially circular recess 46b opened at the tip, and an actuated member 30b protruding from the rear surface of the opening / closing piece 30 is loosely fitted in the opening of each recess 46b. As shown in FIG. 10, the actuated member 30b moves up and down as the actuating arm 46 swings up and down, and the open / close pieces 30 are opened and closed around the shaft 30a. Has been. That is, when the distal end portion of the operating arm 46 is lowered as shown in FIG. 10A, the actuated member 30b is pushed down, so that the opening / closing piece 30 is closed, and conversely, as shown in FIG. 10B. Since the actuated member 30b is pushed up when the tip portion is raised, each open / close piece 30 is in an open state.

Since this opening / closing mechanism 31 is installed in front of the game board surface, when a lock mechanism for preventing unauthorized opening of the opening / closing piece is provided at this portion as in the prior art, the gap between the glass frame and the game board is provided. It was possible to release the lock mechanism by inserting a wire or the like through the gap.
The connecting portion 47 is a protrusion 46d that protrudes from the gap between two discs 47a, the center of which is fixed to the tip of the plunger 44 at a predetermined interval, on the rear upper part of the inner surface of the operating arm 46. When the plunger 44 is in a protruding state, the disk 47a pushes the protrusion 46d forward to lower the tip of the operating arm 46, while the plunger 44 is retracted. When in the state, the disk 47a pulls the protrusion 46d backward to raise the tip of the operating arm 46.

Next, the lock mechanism 60 is supported by the operating arm 46 so as to be rotatable in the same direction as the swinging direction (vertical direction), and locks the operating arm when the coil 42 is in a non-excited state. And a lock member 61 for releasing the prohibition of swinging of the operating arm when the coil is in an excited state. In this example, the lock member 61 is pivotally supported by the horizontal shaft 46c of the operating arm parallel to the shaft support 46a so as to be rotatable in the vertical direction.
The lock member 61 is provided with at least a part of the magnetic body portion 64, and locks the lock member in a state where the magnetic body portion 64 is attracted by the magnetism of the coil when the coil 42 is excited and the swinging of the operating arm 46 is prohibited. It is configured to rotate in the release direction.
The lock member 61 according to this example is supported by a horizontal shaft 46c parallel to the shaft support portion 46a and the protrusion 46d of the operating arm so as to be rotatable in the same direction as the swinging direction of the operating arm (FIG. 4A). )). The horizontal shaft 46c is at a substantially intermediate height position between the shaft support 46a and the projection 46d, and is fixed between the inner walls of the operating arm in front of the shaft support 46a and the projection 46d.
The lock member 61 is mounted on the outer surface of the horizontal shaft 46c and protrudes in the same outer diameter direction from the hollow cylindrical base portion 62 that rotates relative to the horizontal shaft 46c, and both axial ends of the base portion 62. The support piece 63 is different from the support piece 63 from the center of the base 62, and the magnetic pin (magnetic part) 64 made of a magnetic material such as steel supported at both ends by the tip of each support piece 63. And a plate-like stopper piece 65 projecting in the radial direction. As will be described later, the angle formed between the support piece 63 and the stopper piece 65 is such that a part of the lock member 61 is locked by the locking portion 45a and the operating arm 46 is swung (the opening and closing piece is swung in the opening direction). Is set so that the stopper member is brought into contact with the tip of the plunger in the protruding state and the lock member 61 can be held in the lock position.

As will be described later, the magnetic pin 64 is displaced (moved up and down) between a state where it is locked by a locking portion 45a provided on the base member 45 side and a state where the lock is released, thereby locking the magnetic pin 64. The member 61 can lock the operating arm in the lowered position or release the lock so that the arm can be raised. The magnetic pin 64 is configured to release the locked state by the lock member by being attracted by the magnetic force when the coil 42 constituting the solenoid is excited. In addition, since the plunger 44 is comprised from the magnetic body, the magnetic force from a coil acts on a magnetic body pin via the plunger 44. FIG.
Note that the locking portion 45a only needs to be part of the lock member 61 when locked, and the magnetic pin 64 itself may not be locked.
The locking portion 45a is a protruding portion having a sharp tip that protrudes forward from an appropriate position below the base member 45. As shown in FIGS. 5 (a), 6 (a), 7, 8 (a), and 9 (a), the lock member 61 has a part of the lock member 61 (magnetic pin 64) as a locking portion. FIG. 5B, FIG. 6B, FIG. 8C, FIG. 8B, FIG. 9 and FIG. 5B, FIG. 6C, FIG. 6B, FIG. As shown in (b), a part of the lock member 61 (the magnetic pin 64) is disengaged from the tip of the locking portion 45a and moved upward to displace the operating arm from rising. Can do.

Since the lock member 61 is freely supported by the horizontal shaft 46c of the operating arm, when the plunger 44 protrudes by the elastic member 43 because the coil is not energized as shown in FIG. 63, the magnetic pin 64 rotates in the direction of lowering due to the weight of the magnetic pin 64. For this reason, the magnetic pin 64 is locked by the tip of the locking portion 45a and cannot be rotated further downward (clockwise direction). At this time, since the stopper piece 65 is in contact with the distal end surface of the plunger 44 in the protruding state, the locked state between the magnetic body pin 64 and the locking portion 45a can be stably maintained.
If a part of the lock member 61, in this example, the magnetic pin 64 is always in contact with and locked with the locking portion 45a when the solenoid is not excited (state of FIG. 5A), It is also assumed that when the attracting force is generated by energizing and exciting the solenoid, the smooth attraction of the magnetic pin is hindered by the locking portion 45a. Therefore, as shown in FIG. 5A ', there may be a case where the magnetic material pin 64 is intentionally separated from the locking portion 45a to form the clearance C when the solenoid is not excited. In such a configuration, the problem is that the lock member 61 is in the clockwise direction of FIG. 5A 'because the magnetic pin 64 is not in contact with the locking portion 45a during the non-excitation of the solenoid. It will rotate freely (backward). When the lock member rotates freely in the clockwise direction, a situation is also assumed in which the magnetic pin is pulled downward beyond the locking portion. In this case, even if a force for rotating the operating arm 46 in the clockwise direction is applied, the magnetic pin cannot be locked by the locking portion.

Therefore, in the present invention, a stopper piece 65 protruding from the support piece 63 with a predetermined angle is provided, and the clearance piece C is brought into contact with the distal end surface of the plunger in a protruding state. In this case, free rotation of the lock member is prevented. For this reason, the magnetic body pin 64 can be maintained at an optimum position facing the distal end of the engaging portion while maintaining a clearance with the engaging portion 45a, and when the operating arm is biased in the opening direction. When the magnetic pin moves in the locking direction, it immediately fills the clearance and comes into contact with the locking portion to be locked (locked).
While the fulcrum when the operating arm 46 swings is the shaft support 46a, the rotation support shaft of the lock member 61 is a horizontal shaft 46c provided on the upper front side of the shaft support 46a. For this reason, in the process in which the lock member 61 moves up and down around the horizontal axis 46c, a part of the lock member, in this example, the magnetic pin 64 is engaged with or disengaged from the tip of the locking portion 45a. As a result, it is possible to realize locking and unlocking with respect to the swing of the operating arm 46. In order to release the lock member, the magnetic pin is attracted by the electromagnetic force from the solenoid side.
With the above-described configuration, even if the operating arm 46 in the lowered position is lifted by applying force in the direction to open the opening / closing piece 30 illegally using a wire or the like, the magnetic pin 64 does not move the locking portion 45a. Since the locking member 61 prevents the operating arm 46 from being lifted and the plunger 44 from being retracted by being locked, the opening / closing piece 30 cannot be opened.

On the other hand, when energizing the coil 42 and retracting the plunger 44 as shown in FIG. 5B, the magnetic body pin 64 is attracted to the plunger side by the magnetic force transmitted through the plunger made of a high magnetic body. The lock member 61 rotates counterclockwise about the horizontal shaft 46c, and the magnetic pin is detached from the locking portion 45a. After the magnetic pin 64 is detached from the locking portion 45a, the plunger 44 can be retracted against the elastic member 43 as shown in (c).
Note that the magnetic pin 64 may be configured by an electromagnet so that the attractive force of the magnetic pin is increased by electromagnetic force generated by energization of the coil. In this case, when the coil is not energized, the magnetic force of the magnetic pin is appropriately adjusted so that the magnetic pin is easily detached from the plunger 44.

In the variable winning device B having the above-described configuration, the lock mechanism 60 is provided on a portion other than the opening / closing mechanism 31 for opening / closing the opening / closing piece 30, that is, on the solenoid-type driving mechanism 40 side located on the back side of the game board. Therefore, it becomes difficult to release the lock state of the lock mechanism 60 by an unauthorized tool such as a wire inserted from the gap between the glass frame and the game board. That is, since it is difficult to insert a wire or the like from the front side of the game board to the back side, the crime prevention effect can be enhanced. Specifically, as shown in FIG. 5A and the like, the lock member 61 that is locked by being locked by the locking portion 45a can be forcibly rotated in the unlocking direction by a wire or the like. In this case, the operating arm 46 can be swung in the opening direction, but since it is difficult to insert a wire or the like from the game board surface side to the back side, it is possible to reliably prevent fraud.
Further, as shown in FIG. 10A and the like, a force for directly opening the opening / closing piece itself in order to open the opening / closing piece 30 in the closed state illegally, or a force for swinging the operating arm 46 in the opening direction. Even if it is added, as long as the solenoid is in a non-energized state, the lock member 61 rotates and stops in the direction in which the magnetic pin 64 is lowered, so that the magnetic pin 64 hits the locking portion 45a and is locked. . For this reason, even if a force in the opening direction is improperly applied, the opening and closing piece cannot be opened by swinging the operating arm in the opening direction and retracting the plunger.

On the other hand, when the solenoid is turned on, the magnetic pin 64 is attracted in the direction of detachment from the locking portion 45a by the electromagnetic force from the coil or plunger, so that the lock member 61 is moved upward with the horizontal axis 46c as the center. The lock is released to be unlocked, and the operating arm can be swung in the opening direction.
In the above-described embodiment, the example in which the lock mechanism 60 of the present invention is applied to means for locking the unauthorized opening of the electric chew 14 constituting the variable winning device 12 has been described. However, the lock mechanism according to the present invention is a solenoid type. In general, it can be applied as a locking means for an opening / closing piece that opens and closes a winning opening using a drive mechanism. Therefore, for example, the present invention can also be applied to an opening / closing lid that opens and closes a large winning device (attacker) 16.
Further, the variable winning device B of the present invention can be applied to pachinko gaming machines and other gaming machines that use other gaming balls.
