Description

  The present invention relates to a variable winning device for a gaming machine that is fixed to a gaming board of a gaming machine and has a winning opening for receiving a gaming ball on the gaming board, and a gaming machine using the same.

  In a gaming machine, for example, a variable winning device that is generally used as an “attacker” has a structure in which a large rectangular winning opening having a rectangular horizontal shape is closed so as to be opened and closed by a corresponding closing member (winning door). Usually, the winning door is hinged at the lower edge both ends to the front plate (base plate) of the winning device, for example. And it is displaced by the drive means, such as a solenoid, between a closed position that closes the big prize opening and an open position that falls from the closed position to the near side (player side) and opens the big prize opening.

  Here, in a variable prize device in a gaming machine, if the excitation time (energization time) of the solenoid becomes long, the power consumption increases and the heat generation amount also increases, so the life of the solenoid itself is shortened and the heat is generated. There is a risk of adverse effects on surrounding parts. Special attention must be paid to attackers whose winning doors (large winning entrances) are open for a long time at the time of a big hit. On the other hand, since the variable winning device is directly involved in paying out a prize ball, it is likely to be a target of fraudulent acts (commonly known as goto acts). For example, by inserting a foreign object such as a wire into a gaming machine and operating the winning door, solenoid plunger, transmission mechanism that transmits power from the plunger to the winning door, etc. There is a risk that a large number of prize balls may be illegally obtained. Therefore, in order to suppress power consumption and heat generation in the solenoid in particular, it has been proposed to use a self-holding solenoid for the variable winning device (see Patent Document 1).

Japanese Patent Laid-Open No. 7-185077

  In the variable winning device of Patent Document 1, a self-holding solenoid is used to open and close the open / close door (winning door), so that the solenoid is excited (energized) only when the winning door is displaced between the open position and the closed position. The position can be maintained even if the solenoid is demagnetized (non-energized) later. Thereby, power consumption and heat generation can be suppressed, and the durability of the solenoid can be improved.

  However, in the self-holding solenoid disclosed in Patent Document 1, when the head portion of the plunger is displaced to the protruding position, the opening / closing door is displaced to the closed position, and when the head portion is displaced to the retracted position, the opening / closing door is moved to the open position. The opening / closing door and the head portion are connected via a transmission mechanism so as to be displaced. Therefore, in order to intentionally open the closed door when the plunger head is in the protruding position (opening / closing door is closed), the head is opened directly or indirectly via a transmission mechanism or opening / closing door. In addition, it can be pushed in against the magnetic adsorption holding force (for example, the magnetizing force of a permanent magnet) from the protruding position. Since the head portion can be displaced to the retracted position (opening / closing door is opened) by this pushing operation, there is a possibility that a prize ball may be illegally obtained by an illegal act. In addition, since the head portion formed on the plunger is linearly displaced in the vertical direction between the upper protruding position and the lower retracted position, the transmission distance from the plunger to the open / close door becomes relatively long, and the transmission There is a risk that the mechanism becomes complicated and the transmission loss increases.

  It is an object of the present invention to easily prevent an illegal act of intentionally opening a closed winning door, simplify the configuration of a transmission mechanism for transmitting power from a solenoid plunger to the winning door, and consume power. It is another object of the present invention to provide a variable winning device for a gaming machine that can suppress the amount of heat generated and improve the durability of the solenoid, and a gaming machine using the same.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the variable prize winning device for gaming machines of the present invention is:

When the plunger head is in the retracted position, the coupling position is located below the swing axis, the self-holding solenoid is demagnetized, and the plunger is magnetically moved to the retracted position by a permanent magnet. While being held by suction and maintaining the winning door in the closed position, when the plunger head portion is displaced from the retracted position to the protruding position, the swinging movement of the first engaging portion causes the swing axis line to move. The self-holding solenoid is demagnetized when the connecting position moves downward to displace the winning door from the closed position to the open position, and when the plunger head is in the protruding position. The plunger is mechanically resiliently held at the projecting position by the resilient member, and the winning door is maintained at the open position.

Also, such a variable prize device for gaming machines is
In order to introduce a game ball from a game area formed on the board surface of the game board to a winning area facing the rear side opposite to the front side where the player is located, the flow direction in the game area is set as the vertical direction. A variable winning device for a gaming machine having a winning opening that opens in the left-right direction as a crossing direction and fixed to the gaming board,
The game board is parallel to the game board and is arranged so as to be rotatable about a rotation axis extending in the left-right direction, and the prize opening is closed by standing along the game board to introduce the game ball into the prize area. A winning door that displaces to a closed position that disables and an open position that allows the game ball to be introduced into the winning area by opening the winning opening by protruding in a crossing manner to the gaming area;
The head portion formed at the front end portion of the plunger that is arranged in the front-rear direction and linearly displaces with excitation can be demagnetized and held at the backward retracted position and the forward protruding position, respectively . A self-holding solenoid for rotating the winning door around the rotation axis by anteroposterior movement and displacing the winning door to the closed position and the open position;
The winning door is moved to the closed position when the head portion of the plunger is displaced to the retracted position by swinging around a swing axis disposed parallel to the swing axis behind the pivot axis. And a transmission member for directly transmitting the driving force of the plunger to the winning door so as to displace the winning door to the open position when the head portion of the plunger is displaced to the protruding position. by swinging around shaft line, in the course of the head portion before Symbol plunger moves to the extended position from the retracted position, an auxiliary member for assisting the opening operation of the winning door by the transmission member, wherein A transmission mechanism disposed between the winning door and the self-holding solenoid;
The transmission member is connected to a head portion of the plunger and swings as the plunger moves back and forth, and the winning door abuts the winning door behind the pivot axis. A second engagement portion that can be maintained in the closed position, and when the winning door is in the closed position, the connection position between the first engagement portion and the head portion and the second engagement portion, The abutting position with the winning door is configured to be positioned below the swing axis,
When the plunger head is in the retracted position, the connecting position is behind the swing axis, the self-holding solenoid is demagnetized, and the plunger is magnetically moved to the retracted position by a permanent magnet. While the suction door is held and the winning door is maintained in the closed position, when the head portion of the plunger is displaced from the retracted position to the protruding position, the connecting position is moved by the swinging motion of the first engaging portion. The self-holding solenoid is demagnetized when the prize-winning door is displaced from the closed position to the open position and the plunger head is in the protruding position. the plunger Te is mechanically elastically held in the projecting position by the elastic member, there is a case to maintain the winning door to the open position.

  In these variable award winning devices for gaming machines, a plunger is formed by linearly displacing the head portion formed at the front end portion of the plunger of the solenoid linearly in the front-rear direction between the forward protruding position and the backward retracted position. Thus, the transmission distance from the winning door to the winning door can be shortened, and the configuration of the transmission mechanism (for example, the swing arm) can be simplified to form a compact and compact. In addition, a self-holding solenoid is used and the plunger head is demagnetized at the retracted position and the protruding position, so that power consumption and heat generation are suppressed, and the solenoid is improved in durability and energy saving. Can do.

  When the plunger head moves backward, the plunger head maintains the winning door in a closed state by magnetic attraction and holding (for example, a magnetizing force of a permanent magnet), and when it protrudes, it holds a mechanical spring (for example, a biasing force of a compression coil spring). ) To keep the winning door open. Therefore, when the closed winning door is intentionally opened, the plunger head cannot be pushed further from the retracted position, and the head can be directly or against the magnetic holding force. Since the operation of pulling out indirectly (for example, a swing arm) or a winning door is accompanied by a great difficulty, it is possible to easily prevent fraud.

Specifically, the plunger of the self-holding solenoid has a head portion formed at the front end protruding from the main body case,
The self-holding solenoid is wound around the plunger inside the main body case, and is attached to the main body case with a coil that generates electromagnetic force for reciprocating linear movement of the plunger in the longitudinal direction in accordance with the excitation applied voltage. (E.g., built-in) a permanent magnet that attracts and holds the plunger in the retracted position, and a compression coil spring that is interposed between the main body case and the head portion of the plunger and biases the plunger toward the protruding position. And
The electromagnetic force in the plunger suction direction generated by energizing the coil overcomes the biasing force of the compression coil spring to displace the plunger head from the projecting position to the retracted position, and accordingly the winning door is opened via the transmission mechanism. While displacing from the position to the closed position and holding the closed position by the magnetizing force of the permanent magnet when the current to the coil is cut off,
The plunger's head is displaced from the retracted position to the protruding position by overcoming the magnetizing force by the electromagnetic force and biasing force in the plunger push-out direction generated by energizing the coil, and the winning door is closed via the transmission mechanism. While being displaced from the position to the open position, the open position can be held by the urging force when the coil is de-energized.

Further, as a specific aspect of the transmission mechanism, the transmission mechanism includes a transmission member that swings around a swing axis that is arranged in parallel with the rotation axis behind the rotation axis,
The transmission member is connected to the head portion of the plunger and swings as the plunger moves back and forth, and the transmission member abuts the winning door behind the rotation axis to bring the winning door into the closed position. When the winning door is in the closed position, the connecting position between the first engaging portion and the head portion, and the contact position between the second engaging portion and the winning door are both included. It can be configured to be positioned below the swing axis.

  According to this, both the connection position where the first engagement portion and the head portion of the plunger are connected in the transmission member and the contact position where the second engagement portion and the winning door abut are both oscillating the transmission member. Since it is located below the axis, the height is reduced and the size is reduced. Further, in the transmission member, since both the connecting position and the contact position are located below the swing axis, the winning door is in the closed position when the plunger head portion is in the retracted position, and the plunger head portion is in the protruding position. In this case, the self-holding solenoid can be rationally assembled so that the winning door is in the open position.

  For example, if the longitudinal movement axis of the plunger is in the vicinity of the rotation axis in the vertical direction, and the contact position is set to be lower than both the longitudinal movement axis and the rotation axis, the winning door, While keeping the height of the self-holding solenoid and the transmission mechanism lower and more compact, the rotation angle of the transmission member (swinging arm) for opening and closing the winning door can be made relatively large.

  In addition, when the transmission mechanism includes a transmission member that directly transmits the driving force of the self-holding solenoid to the winning door and an auxiliary member that mainly assists the opening operation of the winning door by the transmission member. The winning door can be smoothly and reliably displaced from the closed position to the open position by the assistance of the auxiliary member.

  At this time, the transmission member of the transmission mechanism is connected to the head portion of the plunger and swings as the plunger moves back and forth, and the winning door abuts the winning door behind the rotation axis. The auxiliary member of the transmission mechanism swings in the same direction as the transmission member by making contact with the transmission member and the winning door, respectively, and is based on the transmission member. It can be configured to assist the opening operation of the winning door. According to this, since the winning door can be surely displaced to the open position with a small force, the center of gravity tilts to the open position by its own weight (movement of the center of gravity) when it is located in front of the rotation axis. It can be easily applied to any type of winning door.

  Specifically, in the transmission mechanism, when the head portion of the plunger moves from the retracted position to the protruding position, the auxiliary member contacts the transmission member by contacting at the first contact portion formed between the transmission member and the transmission member. After the rotation, the winning door can be pressed and moved to the open position by making contact with the second contact portion formed between the winning door and the winning door. According to this, since the auxiliary member operates in the form of being rotated around the transmission member, a simple structure can be achieved, and miniaturization and space saving can be achieved.

  At this time, in the closed position of the winning door, the second contact portion (the contact position) may be positioned between the contact position and the connection position in the front-rear direction and below the swing axis in the vertical direction. As a result, the arm length of the second engagement portion can be made relatively long, so the moment for closing the winning door is increased, and the closed state of the winning door can be reliably maintained. If the second contact portion is in a non-contact state (that is, if a gap is provided) when the second engagement portion and the winning door are in contact (that is, when the winning door is in the closed position), the first engagement The twisting of the second engaging portion can be prevented, and the assisting force by the auxiliary member can be increased by the collision (contact) of the second contact portion. In addition, play (instantaneous transmission stop) occurs when the winning door moves from the closed position to the open position by providing a gap that temporarily brings the second contact portion into a non-contact state, Such a temporary non-contact state (play) is included in “transmission of driving force by a transmission mechanism (transmission member)”.

  As the first contact portion, for example, the transmission member side contact portion can be constituted by a pin and the auxiliary member side contact portion can be constituted by a long hole, and the pin and the long hole can be exchanged. Moreover, as a 2nd contact part, a winning door side contact part can be comprised by the rear-end surface part of a winning door, and an auxiliary member side contact part can be comprised with a pin, for example.

  Further, the transmission member is formed with a locking portion that is locked to the winning door in the closed position, and when an external force for forcibly rotating the winning door from the closed position to the open position is applied, The door can be configured to be locked to the transmission member by the engaging portion and prevented from rotating. According to this, since the engaging part for preventing the rotation of the winning door (rotation from the closed position to the opened position) is formed on the transmission member, an external force is applied to the closed winning door by an illegal act. However, it is possible to mechanically prevent the winning door from rotating, thereby further preventing fraud. In addition, when the latching portion is configured by a lock claw that is formed to protrude at the contact position between the second engagement portion and the winning door (the front end portion of the second engaging portion), the winning door is rotated. It can be blocked more firmly.

Therefore, in order to solve the above problems, the gaming machine of the present invention is:
The variable winning device for gaming machine as described above is fixedly arranged on the gaming board.

  As a result, it is possible to extend the life of the solenoid itself without adversely affecting peripheral parts, prevent illegal acquisition of prize balls due to fraud, and realize a gaming machine having an interesting board surface configuration. .

  The winning door 10 has a rectangular plate shape in which the left-right direction is the longitudinal direction when viewed from the front (see FIG. 1), and is, for example, parallel to the game board 2 so as to be fitted in the winning opening 5a. It is arranged so as to be rotatable around a rotation axis O1 extending along the lower side. Then, by standing along the game board 2, the winning opening 5a is closed to make it impossible to introduce the game ball into the winning area 5b (see FIG. 5A) and to the gaming area 2c. By projecting to the open position, the winning opening 5a is opened, and it is rotationally displaced to an open position (see FIG. 5C) that allows the game ball to be introduced into the winning area 5b.

Generate power. The permanent magnet 24 is built in the main body case 29 to attract and hold the plunger 21 in the retracted position. The compression coil spring 25 is interposed between the main body case 29 and the head portion 22 of the plunger 21 and biases the plunger 21 toward the protruding position. That is, the attractive force of the permanent magnet 24 is larger than the urging force of the compression coil spring 25, and the head portion 22 of the plunger 21 is in the retracted position (see FIG. 5A) rather than the protruding position (see FIG. 5C). It is in a more stable state. As shown in FIG. 4, the head portion 22 is connected to the through hole 22a through which the plunger 21 is inserted, and the plunger 21 and the transmission mechanism 30 (specifically, the connection hole 41a of the first arm 41). Connecting portions 22b and 22b are formed.

  Next, as shown in FIGS. 2 and 4, the transmission mechanism 30 swings around the swing axis O <b> 2 arranged in parallel with the pivot axis O <b> 1 behind the pivot axis O <b> 1 of the prize door 10. A swing arm (transmission member) 40 and an auxiliary arm (auxiliary member) 50 are provided. The swing arm 40 displaces the winning door 10 to the closed position when the head portion 22 of the plunger 21 of the self-holding solenoid 20 is displaced to the retracted position, and the winning door when the head portion 22 of the plunger 21 is displaced to the protruding position. The driving force of the plunger 21 is directly transmitted to the winning door 10 so that 10 is displaced to the open position. On the other hand, the auxiliary arm 50 assists (energizes, assists) the opening operation of the winning door 10 by the swing arm 40 mainly in the process of moving the head portion 22 of the plunger 21 from the retracted position to the protruding position.

  As shown in FIG. 3, the swing arm 40 is formed in an L shape, is connected to the head portion 22 of the plunger 21, and swings as the plunger 21 moves back and forth (first engagement). Part) and a second arm 42 (second engagement part) that can contact the winning door 10 behind the rotation axis O1 and maintain the winning door 10 in the closed position. When the winning door 10 is in the closed position, the swing arm 40 has a connection position between the first arm 41 and the head portion 22 and a contact position between the second arm 42 and the winning door 10 (projecting portion 13). Both are assembled so as to be positioned below the swing axis O2.

  Specifically, as shown in FIG. 4, the swing arm 40 includes a spacing member 43 having a predetermined width in the left-right direction, and a pair of left and right first arms 41, 41 are disposed at both ends of the spacing member 43.

  Specifically, the auxiliary arm 50 has an engagement long hole 54 that engages (contacts) the contact pin 41b (the swing arm side contact portion; the first contact portion) of the first arm 41 (the swing arm 40). (Auxiliary arm side contact portion; first contact portion) is formed, and the contact pin 41b and the engagement long hole 54 constitute a first contact portion. The auxiliary arm 50 is provided with an extension 52 formed on the arc-shaped peripheral edge so as to extend in the radial direction with the swing shaft hole 51 as the center. The extension portion 52 includes an assist pin 53 (auxiliary arm) acting (contacting) on the assist receiving portion 14 (door side contact portion; second contact portion) formed on the rear end surface portion of the extension portion 12 of the winning door 10. Side contact portion; second contact portion) is provided along the swing axis O2, and the assist receiving portion 14 and the assist pin 53 constitute a second contact portion. In the first contact portion, the contact pin 41b of the swing arm 40 and the engagement long hole 54 of the auxiliary arm 50 may be replaced with each other.

  As shown in FIG. 3, when the pressing portion 42a of the second arm 42 and the protrusion 13 of the winning door 10 are in contact (that is, when the winning door 10 is in the closed position), the assistance receiving portion of the winning door 10 is received. 14 and the assisting pin 53 of the auxiliary arm 50 are not in contact with each other, and a gap S1 is formed between them. By providing the gap S1, the first arm 41 and the second arm 42 can be prevented from being twisted, and the second arm 42 can collide (engage) to increase the assisting force by the auxiliary arm 50.

  Further, as shown in FIG. 5C, when the winning door 10 is in the open position, the pressing portion 42a of the second arm 42 and the protruding portion 13 of the winning door 10 are separated to form a gap S2 therebetween. ing. As described above, by providing the gaps S1 and S2, play (instantaneous transmission stop) occurs when the winning door moves between the closed position and the open position. The combined state (play) is handled as being included in “transmission of driving force by the transmission mechanism 30 (the swing arm 40)”.

  Accordingly, when the head portion 22 of the plunger 21 moves from the retracted position (see FIG. 5A) to the protruding position (see FIG. 5C), the contact pin 41b constituting the first contact portion is engaged with the long hole. By contacting 54, the auxiliary arm 50 rotates with the swing arm 40. Thereafter, the support pin 53 comes into contact with the support receiving portion 14 constituting the second contact portion (see FIG. 5B; the support position), and the auxiliary arm 50 is pressed so as to jump up (kick up) the winning door 10. By doing so, the winning door 10 is moved to the open position. Thereby, the winning door 10 can be opened reliably.

  In addition, in the closed position of the winning door 10 shown in FIG. 3, the contact position between the assist receiving portion 14 and the assist pin 53 constituting the second contact portion 42 is the second arm 42 (pressing portion 42a) and the winning prize in the front-rear direction. Between the contact position of the door 10 (projection part 13) and the connection position of the first arm 41 and the head part 22, it is located below the swing axis O2 in the vertical direction. According to this, since the length of the 2nd arm 42 can be taken comparatively long, the moment which closes the winning door 10 becomes large, and a closed state can be maintained reliably.

  Next, with reference to FIGS. 1 and 5, the operation of the winning device 4 having the above-described configuration will be described in relation to the gaming state in the gaming area 2c.

<Normal state = closed position>
When returning to the normal state (non-big hit state), the energization in one direction of the coil 23 generates an electromagnetic force in the plunger attracting direction according to the polarity (for example, + polarity) of the excitation applied voltage. When this electromagnetic force overcomes the urging force of the compression coil spring 25, the head portion 22 of the plunger 21 is displaced from the protruding position (FIG. 5C) to the retracted position (FIG. 5A). Accordingly, the winning door 10 is displaced from the open position (FIG. 5C) to the closed position (FIG. 5A) via the transmission mechanism 30. Thereafter, even when the coil 23 is turned off, the winning door 10 is magnetically attracted and held in the closed position (FIG. 5A) by the magnetic force of the permanent magnet 24.

<Big hit state = Open position>
When a game ball flowing down the game area 2c wins the electric chew 8, a winning lottery is executed, and if the lottery result is a big hit, a big hit symbol (for example, “7, 7, 7”) is displayed on the liquid crystal display unit 3. ) Is displayed. In the big hit state, the coil 23 is energized in the reverse direction to generate electromagnetic force in the plunger push-out direction according to the polarity (for example, -polarity) of the excitation applied voltage. The electromagnetic force and the urging force of the compression coil spring 25 overcome the magnetizing force of the permanent magnet 24, whereby the head portion 22 of the plunger 21 is moved from the retracted position (FIG. 5A) to the protruding position (FIG. 5C). Displace to Accordingly, the winning door 10 is displaced from the closed position (FIG. 5A) to the open position (FIG. 5C) via the transmission mechanism 30.

  Specifically, the contact pin 41b constituting the first contact portion is engaged while the head portion 22 of the plunger 21 is moving from the retracted position (FIG. 5A) to the protruding position (FIG. 5C). By contacting the long hole 54, the auxiliary arm 50 rotates with the swing arm 40. Thereafter, at the assisting position (see FIG. 5B), the assisting pin 53 comes into contact with the assisting receiving part 14 constituting the second contact part, and the auxiliary arm 50 jumps up (kicks up) the winning door 10. By pushing in, the winning door 10 is encouraged to lean to the open position (FIG. 5C) by its own weight (movement of the center of gravity). In this way, the winning door 10 rotates around the rotation axis O1 and is displaced to the open position. Thereafter, even if the power supply to the coil 23 is interrupted, the winning door 10 mechanically holds the open position by the urging force of the compression coil spring 25.

  When the proximity switch 7 detects a predetermined number (for example, 10) of winnings in the winning port 5a or when a predetermined time (for example, 30 seconds) has elapsed, the coil 23 is again energized in one direction. The head portion 22 of the plunger 21 is displaced from the protruding position (FIG. 5C) to the retracted position (FIG. 5A), and the winning door 10 is moved from the open position (FIG. 5C) to the closed position (FIG. 5). Displacement to (a)). Thereafter, even when the coil 23 is turned off, the winning door 10 is magnetically attracted and held in the closed position (FIG. 5A) by the magnetic force of the permanent magnet 24. With the above as one round (1R), the opening / closing operation of the winning door 10 is repeated over a predetermined number of rounds (for example, 15R), and the player can acquire a large number of prize balls during this period.

  As described above, the head portion 22 formed at the front end portion of the plunger 21 is straight in the front-rear direction between the front-side protruding position (FIG. 5C) and the rear-side retracted position (FIG. 5A). Accordingly, the transmission distance from the plunger 21 to the winning door 10 can be shortened, and the configuration of the transmission mechanism 30 (for example, the swing arm 40) can be simplified and formed compact and compact. In addition, since the self-holding solenoid 20 is used and the head portion 22 of the plunger 21 is demagnetized at the retracted position and the protruding position, power consumption and heat generation are suppressed, the durability of the solenoid 20 is improved, and energy saving is achieved. Can be achieved.

  The head portion 22 of the plunger 21 maintains the winning door 10 in the closed state by the magnetizing force of the permanent magnet 24 when retreating, and maintains the winning door 10 in the opened state by the biasing force of the compression coil spring 25 when protruding. Therefore, when the winning door 10 in the closed state (FIG. 5A) is intentionally opened, the head portion 22 of the plunger 21 cannot be pushed further from the retracted position (FIG. 5A), and the permanent magnet The operation of pulling out the head portion 22 directly or indirectly through the transmission mechanism 30 (for example, the swing arm 40) or the winning door 10 against the magnetic force of 24 is accompanied by a very difficult operation. Can be easily prevented.
