Description

  The present invention relates to a board role of a gaming machine such as a pachinko gaming machine or an arrangement ball gaming machine, and more particularly to a board role that can effectively prevent an unauthorized operation using a magnet.

As this type of board role, there are a pair of left and right movable wing pieces that can be rotated between a tilting posture and a standing posture, and an operation arm that opens and closes the movable wing pieces from the rear by a vertically moving tip. The operating arm is attracted and raised by an electromagnetic solenoid that is energized to rotate the movable wing piece into a tilted and open posture. Unauthorized operation that opens a movable wing piece by attracting and raising the operation arm by applying a magnetic field from a powerful magnet to the front of the game board against such a board role even though the electromagnetic solenoid is not energized May be performed. Therefore, in order to prevent such an unauthorized operation, in Patent Document 1, a shield plate made of a magnetic material is attached to the front surface of the cover body located in front of the left and right movable wing pieces, and the front of the game board is attached. The magnetic field is prevented from acting on the operation arm.

  However, in recent years, magnets used for unauthorized operations have become extremely powerful, such as rare earth elements, and there has been a problem that unauthorized operations cannot be completely prevented with the above-described conventional structure.

  Therefore, the present invention solves such a problem, and an object of the present invention is to provide a gaming machine board feature capable of effectively preventing an illegal act of opening a movable wing piece using a strong magnet. And

  In order to achieve the above object, in the present invention, a pair of left and right movable wing pieces (3) that can rotate and an operating arm (3) that rotates the movable wing piece (3) by a tip portion (52) that moves up and down ( 5) and bent in a substantially L shape, with its vertical wall (61) positioned in front of the movable wing piece (3) and its lateral wall (62) at the distal end (52) of the operating arm (5). And a magnetic body (6) which is extended downward and positioned below the magnetic body (6).

  In the present invention, even if a strong magnet magnetic field is applied from the front of the game board in the direction of tilting the movable wing piece, the magnetic magnetic field is caused by the fact that the horizontal wall of the magnetic body is located below the tip of the operation arm. Since the acting magnetic body and the tip of the operation arm are close to each other, a large attractive force is generated by the magnetic force, and the operation arm is strongly held in the downward rotation position. For this reason, the operation arm is not attracted to the magnetic field and does not rotate upward.

  In addition, the code | symbol in the said parenthesis shows the correspondence with the specific means as described in embodiment mentioned later.

  As described above, according to the board role of the gaming machine of the present invention, it is possible to effectively prevent an illegal act of opening the movable wing piece using a strong magnet.

  FIG. 1 shows a front view of an electric accessory as an example of a board accessory, and FIG. 2 shows a side view thereof. 3 is a sectional view taken along line III-III in FIG. 1, FIG. 4 is a sectional view taken along line IV-IV in FIG. 1, and FIG. 5 is a sectional view taken along line V-V in FIG. The electric accessory 1 is provided with a housing part 11 to be mounted in the mounting opening P1 (FIG. 2) of the game board P. In the housing part 11, the flow path 13 (FIG. 4) of the game ball is arranged in the lower half. And an electromagnetic solenoid 2 is installed in the upper half. A large-diameter mounting flange 14 (FIG. 1) is formed at the front end of the housing portion 11, and the housing portion 11 is fixed to the game board P by attachment holes 141 provided at two places on the left and right sides thereof.

  A cover portion 4 is fixed to the front surface of the mounting flange 14 so as to protrude forward with a substantially L-shaped cross section, and the movable blade 3 is located in the left and right positions between the mounting flange 14 in the inner space of the cover portion 4. It is arranged. The movable wing piece 3 is rotatably supported by a shaft body 411 (FIG. 5) protruding from the inner surface of the standing wall 41 of the cover portion 4, and each figure shows a closed posture in which the movable wing piece 3 stands. Indicates the state. In addition, the lower outer periphery 14a of the mounting flange 14 is notched in a straight line, and a concave space S is formed between the rear surface of the lower end of the cover portion 4 and the front surface of the game board P as shown in FIG. In such a concave space S, the upper end of a mounting flange R (FIG. 2) of a variable prize device or the like provided below the electric accessory 1 can be inserted, so a gaming board surface with a limited component mounting area is effective. Can be used for

  A plate-like operation arm 5 is disposed in the casing 11 below the electromagnetic solenoid 2. The operation arm 5 is provided so as to be inclined downward in the forward direction, and a base end 51 of the operation arm 5 is supported in the housing portion 11 so as to be rotatable in the vertical direction. The operating arm 5 has a bifurcated tip and extends into the cover 4 as a leg 52 (FIG. 3), and the tip of each leg 52 is positioned below the left and right movable wing pieces 3 (FIG. 5). . A leaf spring 53 (FIGS. 3 and 4) is disposed between the operation arm 5 and the electromagnetic solenoid 2 to urge the operation arm 5 downward. When the electromagnetic solenoid 2 is energized, the operating arm 5 is attracted and rotated upward against the spring force of the leaf spring 53, and its leg portion 52 moves upward to the inner lower end of each movable wing piece 3. It enters into the formed notch 31 (FIG. 5) and pushes it up. Thereby, each movable wing piece 3 is tilted and rotated outwardly to be in an open posture.

  When the energization of the electromagnetic solenoid 2 is stopped, the operation arm 5 is rotated downward by the spring force of the leaf spring 53 and its own weight, and each movable blade piece 3 returns to the standing closed posture. In this state, when a magnetic field is applied from the front of the game board with a strong magnet and the operation arm 5 is attracted and rotated upward against the spring force of the leaf spring 53, the movable wing piece 3 is in an open posture. End up.

  Here, in this embodiment, the magnetic plate 6 as shown in FIG. The magnetic plate 6 is formed by punching a cold-rolled steel plate or a galvanized steel plate with a press and then bending it into an L shape. The vertical wall 61 is formed in an outer shape along the shape of the front surface of the standing wall 41 of the cover portion 4. (See FIG. 1). Further, the horizontal wall 62 of the magnetic plate 6 is formed in a shape having leg portions 621 protruding in the left and right positions, and the formation positions of both leg portions 621 correspond to the leg portions 52 of the operation arm 5.

  As shown in FIGS. 1 and 3, the magnetic plate 6 is mounted in a recessed portion 413 formed with a vertical wall 61 on the front surface of the standing wall 41 of the cover portion 4, and a horizontal wall 62 is formed on the standing wall 41 of the cover portion 4. The leg portions 621 are inserted into the horizontally long openings 412 and extend into the space of the cover portion 4, and the tips of the leg portions 621 are positioned close to the tips of the leg portions 52 of the operation arm 5. In this case, each leg portion 621 of the horizontal wall 62 does not necessarily have to be directly below each leg portion 52 of the operation arm 5, and may be slightly shifted in the left-right direction and the front-rear direction. As shown in FIG. 7, the surface of the vertical wall 61 of the magnetic plate 6 is covered with a seal 7 on the entire surface of the recessed portion 413.

  Even if a strong magnetic field is applied from the front of the game board P to the electric accessory 1 having such a structure, the tip of the lateral wall leg 621 of the magnetic plate 6 is close to the tip of the leg 52 of the operation arm 5. When the magnetic field loops and the magnetic field acts, a large attractive force is generated between the adjacent leg portions 621 and 52, and the operation arm 5 is strongly held in the downward rotation position. As a result, the operation arm 5 is not sucked and rotated upward.
