Description

  The present invention relates to a winning device for gaming machines and a gaming machine equipped with the same.

  In a gaming machine, for example, a winning device generally used as an “attacker” has a structure in which a large rectangular winning opening (winning opening) having a longitudinal direction on the left and right is closed so as to be opened and closed by a corresponding winning door (rotating body) It has become. Usually, the winning door is hinged at the lower edge both ends to the front plate (base plate) of the winning device, for example. Such a winning door has a closed position (first position) that stands up and closes the big winning opening by a linear drive type solenoid (linear actuator) and a transmission mechanism such as a swing arm (transmission member), and the closing thereof. Rotate and displace between the open position (second position) that falls from the position to the near side (player side) and opens the big prize opening.

  In such a winning device, the main part (solenoid, swinging arm, etc.) may be housed in a casing that is divided into upper and lower case bodies in consideration of assembly. At that time, a structure is disclosed in which the shaft portion (swing shaft) of the open / close second link (swing arm) is held by a bearing portion formed in the main body case (lower case body) (see Patent Document 1). .

Japanese Patent No. 4017820

  In a winning apparatus as shown in Patent Document 1, a solenoid and a transmission mechanism such as an open / close second link are connected, and a shaft portion of the open / close second link is used as a bearing portion (a bottom wall portion, a front wall portion, and a rear portion of the main body case). Assembling work can be easily performed by inserting into the accommodation space surrounded by the wall portion from above and placing it on the bearing portion (bottom wall portion). By the way, the solenoid plunger (driving member) is biased to the protruding position by a compression coil spring (biasing member) when not energized (including assembly). Therefore, for example, if the shaft portion of the opening / closing second link is assembled in a state where it is detached from the bearing portion or lifted by the urging force of the compression coil spring because it is unfamiliar with the assembly work, the shaft portion is damaged or the opening / closing second link There is concern about the possibility of malfunction.

  An object of the present invention is to improve the assembling property to the swinging shaft receiving portion, so that the mounting failure of the swinging shaft is less likely to occur, and the swinging shaft is not damaged or the transmission member is not erroneously operated. An object is to provide a device and a gaming machine using the device.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-described problems, the prize winning device for gaming machine of the present invention is:
A winning door that is parallel to the game board and is rotatable about a rotation axis extending in the left-right direction, displaceable between a closing position for closing the winning opening and an opening position for opening the winning opening, and a plunger in front A linear drive type solenoid that displaces the winning door to the closed position and the open position by linearly displacing to the protruding position on the side and the retracted position on the rear side, and biasing the plunger to the protruding position And a biasing member disposed between the winning door and the solenoid, and swinging around a swinging axis parallel to the pivoting axis to convert linear movement of the plunger into pivoting of the winning door A prize-winning device for a gaming machine comprising a transmission member for transmitting
A casing including at least a base body for accommodating the solenoid and the transmission member, and a cover body that covers the base body from either the upper or lower direction,
The base body is formed with a bag-like rocking shaft accommodating portion that opens to the rear side in an attached state to the game board in order to receive a rocking shaft formed integrally with the transmission member.
The swinging shaft is inserted and held in the swinging shaft housing portion by the biasing force of the biasing member inserted from the rear opening .
The cover body is formed with a closing portion for closing the opening of the swing shaft accommodating portion,
After inserting the pivot shaft, by covering the base body in the cover body, the pivot shaft receiving portion is characterized Rukoto is closed by the closing portion.

  In such a gaming machine winning device, the bag-shaped (pocket-shaped) rocking shaft housing that opens to the rear side has a rocking shaft formed integrally with a transmission member (for example, a rocking arm) from the rear. A rocking shaft housing space that can be inserted and held is configured. Therefore, if the swinging shaft is inserted from the rear opening, the swinging shaft does not come off from the swinging shaft housing portion due to the biasing force of the biasing member (for example, the compression coil spring), but rather the biasing force is not increased. By using this, the swing shaft can be smoothly attached to the swing shaft housing. As described above, it is possible to improve the assemblability to the rocking shaft housing portion, and it is difficult for the rocking shaft to be assembled poorly, so that the rocking shaft is not damaged or the transmission member is not erroneously operated.

For example, when configuring the base body with the lower case body and the cover body with the upper case body,
The lower case body includes a bottom wall portion extending forward and backward to receive a swing shaft formed integrally with the transmission member, a front wall portion rising upward from a front end portion of the bottom wall portion, and the front wall A protruding wall portion extending in a bowl shape from the upper end portion of the portion to the rear is integrally formed,
The bag-shaped space (swing shaft housing portion) surrounded by the bottom wall portion, the front wall portion, and the protruding wall portion constitutes a swing shaft housing space in which the swing shaft can be inserted and held from the rear. be able to.

  That is, a bottom wall portion extending in the front-rear direction, a front wall portion rising upward from a front end portion of the bottom wall portion, and a bowl shape (and parallel to the bottom wall portion) from the upper end portion of the front wall portion to the rear. Since the protruding wall portion is formed integrally, the swing shaft can be inserted and held in the swing shaft housing portion (bag-shaped (pocket-shaped) space) from the rear. As described above, the swinging shaft is inserted into the hook-shaped projecting wall portion, so that the swinging shaft is prevented from being detached or lifted by the biasing force of the biasing member, and the swinging shaft is assembled to the swinging shaft housing portion. Becomes easier.

Further, by a closing portion and the rocking shaft accommodating portion, since the closure-shaped pivot shaft accommodation space is formed, to suppress the rattling of the inserted pivot shaft holding the rotating (swinging), The transmission member and the winning door can be operated smoothly. For example, the closing portion may be formed of a rear wall portion that is integrally formed with the upper case body and extends in parallel to face the front wall portion.

At this time, the rocking shaft accommodating portion of the base body is formed with a contact portion that contacts the rocking shaft from the outside in the vertical direction toward the rear, while the closing portion of the cover body extends forward. Forming an extension,
The extension portion can keep rotating about the swing axis of the swing shaft by contacting the swing shaft together with the contact portion from the outside in the vertical direction.

  By the extension part and the contact part, the rotation (swinging) of the swinging shaft can be held more reliably. Even if the contact portion extends rearward in a cantilevered manner, the strength of the contact portion can be supplemented by the extension portion. As a result, the transmission member can be smoothly rotated (oscillated) over a long period of time. For example, the contact portion may be constituted by a projecting wall portion extending in a bowl shape rearward from the upper end portion of the front wall portion, and the extension portion may be constituted by a ceiling wall portion extending forward from the rear wall portion. Good.

In addition, the award winning device for gaming machine as described above is
A winning door that is parallel to the game board and is rotatable about a rotation axis extending in the left-right direction, displaceable between a closing position for closing the winning opening and an opening position for opening the winning opening, and a plunger in front A linear drive type solenoid that displaces the winning door to the closed position and the open position by linearly displacing to the protruding position on the side and the retracted position on the rear side, and biasing the plunger to the protruding position And a biasing member disposed between the winning door and the solenoid, and swinging around a swinging axis parallel to the pivoting axis to convert linear movement of the plunger into pivoting of the winning door A prize-winning device for a gaming machine comprising a transmission member for transmitting
A casing including at least a base body for accommodating the solenoid and the transmission member, and a cover body that covers the base body from either the upper or lower direction,
The swing shaft integrally formed with the transmission member is formed with a fan-shaped cutout portion cut out in a predetermined range in the circumferential direction toward the front,
The base body has a bag-like swing having an engagement portion that opens rearward to receive the swing shaft and protrudes rearward to engage with a notch portion of the swing shaft. A shaft housing part is formed,
The cover body is formed with a closing portion for closing the opening of the swing shaft accommodating portion, and an extending portion extending forward from the closing portion,
After the swing shaft is inserted from the rear opening and is housed and held in the swing shaft housing portion by the biasing force of the biasing member, the swing shaft housing portion is covered with the cover body. When the extension portion is closed by the closing portion, the extension portion has a step in the vertical direction and is positioned outside the engagement portion, so that the swing shaft extends in the swing shaft housing portion. It moves back and forth along the part, and the notch part may be engageable / detachable with the engaging part.

  In such a gaming machine winning device as well, the bag-like (pocket-shaped) rocking shaft accommodating portion that opens to the rear side is located behind the rocking shaft that is integrally formed with the transmission member (for example, a rocking arm). The rocking shaft accommodating space that can be inserted and accommodated is constructed. Therefore, if the swinging shaft is inserted from the rear opening, the swinging shaft does not come off from the swinging shaft housing portion due to the biasing force of the biasing member (for example, the compression coil spring), but rather the biasing force is not increased. By using this, the swing shaft can be smoothly attached to the swing shaft housing. As described above, it is possible to improve the assemblability to the rocking shaft housing portion, and it is difficult for the rocking shaft to be assembled poorly, so that the rocking shaft is not damaged or the transmission member is not erroneously operated. In addition, since the rocking shaft housing portion and the closing portion form a closed rocking shaft housing space, the back and forth movement and rotation (rocking) of the rocking shaft inserted can be suppressed by suppressing rattling of the inserted rocking shaft. The transmission member and the winning door can be smoothly operated. In addition, since the swing shaft moves back and forth along the extending portion in the swing shaft housing portion, and the notch portion can be engaged with and disengaged from the engagement portion, the transmission member and the winning door can be reduced overall. Even if the transmission member (the swing axis thereof) is moved back and forth, the rotation angle of the winning door can be increased even if the length (full length) of the transmission member is equal, or the rotation angle of the winning door is increased. Even if it is equivalent, since the total length of the transmission member can be shortened, it is easy to downsize the structure of the winning device.

For example, when configuring the base body with the lower case body and the cover body with the upper case body,
The lower case body includes a bottom wall portion extending forward and backward to receive a swing shaft formed integrally with the transmission member, a front wall portion rising upward from a front end portion of the bottom wall portion, and the front wall While the protruding wall portion extending in a bowl shape from the upper end portion of the portion to the rear is integrally formed,
The upper case body has a rear wall portion extending in parallel to face the front wall portion, and extends forward from the rear wall portion to approach or contact the projecting wall portion from above and between the projecting wall portion. The ceiling wall that forms the upper and lower steps is integrally formed,
The closed space surrounded by the bottom wall portion, the front wall portion, the protruding wall portion, the rear wall portion, and the ceiling wall portion is covered with the upper case body after the swing shaft is inserted into the lower case body from the rear. As a result, it is possible to configure a rocking shaft housing space that can house and hold the rocking shaft in a form that slides back and forth on the bottom wall portion and rocks around the rocking axis.

  In such a prize-winning device for a gaming machine, between the notch portion of the swing shaft and the engaging portion of the swing shaft housing portion, the swing shaft is allowed to move in the front-rear direction while being allowed to move around the swing axis. It is possible to form a rocking prevention part that prevents rocking at the position and a movement blocking part that prevents movement in the front-rear direction while allowing rocking of the rocking shaft around the rocking axis.

  As described above, the notch portion of the swinging shaft accurately transmits the driving force of the plunger to the winning door and functions smoothly as a lock portion that prevents unauthorized opening of the winning door due to external force. In addition, by forming the rocking prevention part and the movement prevention part between the notch part and the engaging part, the configuration of the lock mechanism is simplified, and the number of parts and Manufacturing costs can be reduced by reducing the number of assembly steps.

  Further, the extending portion contacts the swing shaft from the outside in the vertical direction, thereby holding the swing shaft in the front-rear direction and rotating around the swing axis in the swing shaft housing portion. be able to.

  The extension portion can hold the swing shaft back and forth and rotate (swing) more reliably. Even when the engaging portion that engages with the notch portion of the swing shaft extends rearward in a cantilevered manner, the strength of the engaging portion can be supplemented by the extending portion. Thus, the transmission member can be smoothly moved back and forth and rotated (oscillated) over a long period of time.

Therefore, in order to solve the above problems, the gaming machine of the present invention is:
The award winning device for a gaming machine as described above is characterized in that it is fixedly arranged on the gaming board in a state where the opening of the swing shaft accommodating portion is located on the rear side.

  As described above, by improving the assemblability to the swinging shaft housing portion, it is difficult to cause the mounting failure of the swinging shaft, and it is difficult to cause damage to the swinging shaft or malfunction of the transmission member (for example, the swinging arm). A winning device can be provided, and a gaming machine having an interesting board surface configuration can be easily realized.

As shown in FIG. 1, on the board surface (front surface) of the game board 2 of the pachinko machine 1 (game machine), the left half of the circumference is partitioned by two inner and outer launch rails 2b to form a circular game area 2a as a whole. Has been. A liquid crystal display unit 3 is mounted at the center of the game area 2a, and a big winning device 4 (winning device) is disposed below the liquid crystal display unit 3 (lower center of the game region 2a). In addition, a start winning device 7 composed of an electric tulip (electric Chu) is disposed between the liquid crystal display unit 3 and the big winning device 4.

  The grand prize winning device 4 is fixed to the game board 2 by a base plate 5 made of a polymer material (for example, synthetic resin such as ABS resin). The base plate 5 is formed to penetrate in the thickness direction (front-rear direction), and has a rectangular shape that opens in the vertical direction in the flowing direction in the game area 2a and in the left-right direction that is the intersecting (for example, orthogonal) direction as the longitudinal direction. It has a large winning opening 5a (winning opening) (see FIG. 2). Therefore, a game ball (not shown) launched from the launch rail 2b is introduced from the game area 2a formed on the board surface of the game board 2 through the big prize opening 5a to the rear prize area 4a. (See FIG. 7).

  In this specification, the up and down direction means a direction (for example, a vertical direction) in which the game ball flows down along the board surface of the game board 2. Further, the left-right direction means a direction (for example, a horizontal direction) intersecting with the up-down direction in a form along the board surface of the game board 2, and means the left side and the right side when viewed from the player side. Further, the front-rear direction means a direction intersecting (for example, orthogonal) with the game board 2, the player side (front side) is the front side, and the opposite side (back side) is the rear side.

  In FIG. 2, a casing 6 (fixed side member) made of a polymer material (for example, synthetic resin such as polycarbonate (PC)) is provided on the rear surface (back surface) of the base plate 5 (see FIG. 1) constituting the grand prize winning device 4. ) Is attached. The casing 6 is composed of an upper case body 6U (cover body) and a lower case body 6D (base body). Both the case bodies 6U and 6D are integrated, and either one of the case bodies (for example, the lower case body). The body 6D) is fixed to the base plate 5.

  As shown in FIG. 3, the winning device 4 has a winning door 10 arranged corresponding to the winning port 5a (see FIG. 2) and a plunger 21 (driving member; see FIG. 5) in the front-rear direction. And a linear drive type solenoid 20 (linear actuator) arranged so as to be displaced to a distance, and a transmission mechanism 50 arranged between the winning door 10 and the solenoid 20 to transmit the driving force of the plunger 21 to the winning door 10. ing. The winning door 10, the solenoid 20, and the transmission mechanism 50, which are the main parts of the big winning device 4, are accommodated and placed in the casing 6. The casing 6 also houses a proximity switch (winning ball detector) for detecting a winning ball to the big winning device 4, a light emitting substrate for illuminating the inside of the big winning device 4, and the like. In either case, illustration is omitted.

  As shown in FIGS. 2 and 3, the winning door 10 has a rectangular plate shape in which the left-right direction is the longitudinal direction when viewed from the front, and closes the big winning opening 5 a. Specifically, the winning door 10 is disposed at the front end portion of the upper case body 6U that is open on the front side corresponding to the large winning opening 5a, and is parallel to the game board 2 (see FIG. 1) and is the large winning opening 5a. It is pivotally supported by the lower case body 6D so as to be rotatable around a rotation axis O1 extending along the lower side. The winning door 10 may be supported on the base plate 5. In this way, the winning door 10 stands along the game board 2 to close the large winning opening 5a and disable the introduction of the game ball into the winning area 4a (first position; see FIG. 6). ), And an open position (second position; see FIG. 7) that allows the game ball to be introduced into the winning area 4a by opening the big winning opening 5a by projecting into the gaming area 2a (see FIG. 1). ).

  The winning door 10 has pivot shafts 11 and 11 projecting left and right along the pivot axis O1 at the lower ends of both sides, and the pivot shafts 11 and 11 are rotatable to the lower case body 6D. It is supported (see FIGS. 6 and 7). In addition, it is good also as a form which forms a shaft hole instead of the rotating shafts 11 and is supported from the lower case body 6D or the base plate 5 side. Further, the winning door 10 is formed with side wall portions 12 and 12 extending rearward on both sides, and a round shaft shape is formed on the rear end portion of the left side wall portion 12 as viewed from the player side (one end side). The protruding portion 13 is formed so as to protrude outward from the left end face in parallel with the rotation axis O1 (see FIGS. 6 and 7). As will be described later, the projecting portion 13 constitutes an operated portion that receives an action from the transmission mechanism 50 (a swing arm 40 described later).

  As shown in FIG. 5, the solenoid 20 is disposed in the front-rear direction at the left end portion of the winning door 10, and includes a plunger 21 having a head portion 22 formed at a front end portion protruding from the solenoid case 29, a solenoid case 29, and a later-described. And a compression coil spring 23 (biasing member) interposed between the head cover 30 and the head cover 30. The solenoid 20 holds the head portion 22 in a forward protruding position (see FIG. 6) and a backward retracted position (see FIG. 7), thereby rotating the winning door 10 around the rotation axis O1. Then, it is displaced between a closed position (see FIG. 6) and an open position (see FIG. 7). Specifically, in a normal state, the solenoid 20 is demagnetized, and the compression coil spring 23 biases the plunger 21 toward the protruding position, and holds (displaces) the winning door 10 in the closed position. On the other hand, in the big hit state, the solenoid 20 is excited, the plunger 21 moves to the retracted position against the urging force of the compression coil spring 23, and holds (displaces) the winning door 10 in the open position.

  Reference numeral 24 denotes a spring receiving member (for example, a washer) that can receive the compression coil spring 23 on the head cover 30 side when inserted into the plunger 21 together with the compression coil spring 23. When the washer 24 receives the urging force of the compression coil spring 23 on the outer surface of the head cover 30, the compression coil spring 23 cannot enter a holding portion 33 formed on the head cover 30 described later. As a result, the holding portion 33 is reliably held by the head portion 22 and the washer 24 of the plunger 21.

  Next, the transmission mechanism 50 is arranged in the front-rear direction along the plunger axis O <b> 3 (movement axis of the drive member) at the left end portion of the winning door 10. The transmission mechanism 50 is attached to the head portion 22 of the plunger 21 and has a head cover 30 (a connecting member) that moves back and forth integrally with the head portion 22 and a rotation axis line behind the rotation axis O1 of the winning door 10. It has a swing arm 40 (transmission member) engaged with the head cover 30 while swinging around a swing axis O2 arranged in parallel with O1 (see FIGS. 6 and 7). When the head portion 22 of the plunger 21 of the solenoid 20 is displaced to the protruding position, the swing arm 40 displaces the winning door 10 to the closed position (see FIG. 6), and when the head portion 22 of the plunger 21 is displaced to the retracted position. The driving force of the plunger 21 is transmitted to the winning door 10 through the head cover 30 so as to displace the winning door 10 to the open position (see FIG. 7). The swing axis O2 may be orthogonal to the plunger axis O3 (see FIGS. 6 and 7).

  As shown in FIG. 4, the head cover 30 slides and guides a cylindrical swing shaft 42 (swing shaft) integrally formed on both side surfaces of the swing arm 40 by the long hole-shaped recess 32 (FIG. 6). , See FIG. 7), the engaging pin 31 protruding in parallel with the swing axis O2 (cylindrical swing shaft 42) is inserted (arranged) into a first recess 40 of the first arm 40a described later. In addition, the holding portion 33 is held by the head portion 22 of the plunger 21 (see FIG. 5).

  The swing arm 40 is formed in a bent shape, and can contact (engage) the winning door 10 behind the first arm 40a (first swing portion) that can be connected to the head cover 30 and the rotation axis O1. Second arm 40b (second swinging portion) (see FIGS. 6 and 7). Specifically, the first arm 40a is formed with a part of an outer peripheral edge and a first notch-shaped recess 41 opened upward. The first arm 40 a (swinging arm 40) is connected to the cylindrical swinging shaft 42 (swinging axis O 2) by engaging the first notched recess 41 with the engaging pin 31 protruding from the head cover 30. Swing displacement around is possible. On the other hand, in the second arm 40b, a part of the outer peripheral edge is removed, and a second notch-shaped recess 43 is formed in the front side. The second notch-shaped recess 43 engages with the protrusion 13 of the side wall 12 on the rear side of the rotation axis O1, thereby closing the winning door 10 (see FIG. 6) or opening (see FIG. 7). Can be maintained.

  As shown in FIGS. 3 to 5, the lower case body 6 </ b> D includes a bottom wall portion 60 that extends horizontally in the front-rear direction to receive the cylindrical swing shaft 42, and a front end portion of the bottom wall portion 60. A front wall portion 61 that rises vertically upward from the top wall and a protruding wall portion 62 (contact portion) that extends from the upper end portion of the front wall portion 61 to the rear in a bowl shape and parallel to the bottom wall portion 60 are integrally molded. Yes. The bottom wall portion 60, the front wall portion 61, and the protruding wall portion 62 constitute a bag-like (pocket-shaped) rocking shaft housing portion in which the cylindrical rocking shaft 42 is housed. On the other hand, the upper case body 6U has a rear wall 63 (blocking portion) extending in parallel to face the front wall 61, and a ceiling extending in parallel with the bottom wall 60 from the rear wall 63 to the front. The wall portion 64 (extending portion) is integrally formed. The bottom wall portion 60, the front wall portion 61, the protruding wall portion 62, the rear wall portion 63, and the ceiling wall portion 64 form a pair of left and right closed swing shaft accommodation spaces S surrounding the cylindrical swing shaft 42. The Note that the lower surface of the protruding wall portion 62 and the lower surface of the ceiling wall portion 64 are arranged flush with each other when viewed from the direction of the swing axis O2, and come into contact with the cylindrical swing shaft 42 from above and Holds rotation (oscillation).

  In order to assemble the swing arm 40 of the transmission mechanism 50 to the casing 6, the cylindrical swing shaft 42 is moved from the rear opening of the swing shaft housing portion formed in the lower case body 6 </ b> D to the bowl-shaped protruding wall portion 62. It is inserted so as to be submerged in and stored in a bag-shaped (pocket-shaped) rocking shaft accommodating space S. At this time, the oscillating arm 40 is urged forward by the urging force of the compression coil spring 23, so that the cylindrical oscillating shaft 42 abuts on the front wall portion 61 and is accommodated and held in the oscillating shaft accommodating portion. Thereafter, by covering the upper case body 6 </ b> U, the swing shaft housing portion is closed by the rear wall portion 63, and the swing arm 40 is assembled to the casing 6. At this time, the cylindrical rocking shaft 42 is housed and held in the closed rocking shaft housing space S.

  In this way, by letting the cylindrical swing shaft 42 go into the bowl-shaped protruding wall portion 62, the cylindrical swing shaft 42 is prevented from being detached or lifted by the urging force of the compression coil spring 23, and the swing shaft housing is accommodated. Assembling property to the portion (swinging shaft accommodation space S) can be improved. Therefore, since the assembly failure of the cylindrical swing shaft 42 is less likely to occur, damage to the cylindrical swing shaft 42 and malfunction of the swing arm 40 are less likely to occur. Further, after the cylindrical swing shaft 42 is inserted from the rear into the swing shaft accommodating portion (bag-like space) of the lower case body 6D, the upper case body 6U is covered, so that the swing shaft accommodating portion becomes the rear wall portion 63. (Closed rocking shaft accommodation space S is formed), so that the cylindrical rocking shaft 42 inserted is prevented from rattling and holds its rotation (rocking), and the rocking arm 40 and the winning door 10 can be operated smoothly. Furthermore, since the ceiling wall portion 64 contacts the cylindrical rocking shaft 42 together with the protruding wall portion 62 from above, the rotation (rocking) of the cylindrical rocking shaft 42 can be held more reliably and the protruding wall portion 62 can be held. The rocking arm 40 can be smoothly rotated (swung) over a long period of time.

  Next, the operation of the special winning device 4 having the above-described configuration will be described with reference to FIGS.

<Normal state = closed position> (FIG. 6)
In the normal state (non-big hit state), the solenoid 20 is demagnetized, the compression coil spring 23 biases the plunger 21 toward the protruding position, and holds the winning door 10 in the closed position. Specifically, when the plunger 21 of the solenoid 20 moves forward from the retracted position (FIG. 7) to the protruding position (FIG. 6), the engagement pin 31 of the head cover 30 moves forward together with the long hole-shaped recess 32, and the cylindrical rocking motion occurs. The moving shaft 42 (oscillation axis O2) rotates clockwise (in the direction of the broken line arrow) in FIG. As a result, the winning door 10 rotates counterclockwise (in the direction of the broken arrow) in FIG. 7 around the rotation axis O1, and the large winning opening 5a is closed.

<Big hit state = open position> (FIG. 7)
In the big hit state, the solenoid 20 is excited, the plunger 21 moves to the retracted position against the biasing force of the compression coil spring 23, and the winning door 10 is held in the open position. Specifically, when the plunger 21 is retracted from the protruding position (FIG. 6) to the retracted position (FIG. 7), the engaging pin 31 is retracted together with the elongated hole 32, and the cylindrical swing shaft 42 (swing) The axis O2) rotates counterclockwise (in the direction of the solid arrow) in FIG. As a result, the winning door 10 rotates clockwise (in the direction of the solid line arrow) in FIG. 7 around the rotation axis O1 and the big winning opening 5a is opened, so that the game balls flowing down the gaming area 2a are in the winning area 4a. Will be introduced.

Further, a lock mechanism is provided between the casing 6 (the upper case body 6U and the lower case body 6D) and the swing arm 140.

  The lower case body 6D includes a bottom wall portion 160 (sliding portion) that extends horizontally in the front-rear direction to receive the cylindrical swing shaft 142, and a front wall portion that rises vertically upward from the front end portion of the bottom wall portion 160. 161 and an engagement wall portion 162 (engagement portion) that extends from the upper end portion of the front wall portion 161 in a bowl shape to the rear and in parallel with the bottom wall portion 160 are integrally formed, and the swing shaft accommodating portion is It is composed. The upper case body 6U includes a rear wall 163 (blocking portion) that extends in parallel to face the front wall 161, and a ceiling that extends forward from the rear wall 163 in parallel with the bottom wall 160. The wall part 164 (extension part) is integrally formed.

  The engaging wall portion 162 that constitutes the swing shaft accommodating portion extends horizontally from the upper end portion of the front wall portion 161 to the rear in a bowl shape. The front end surface (rear end surface) of the engagement wall portion 162 moves in a predetermined direction (for example, the vertical direction) in order to prevent the swing arm 140 from swinging around the swing axis O2 and prevent forward movement. A blocking surface 162x (movement blocking unit; lock mechanism) is formed. On the other hand, the lower surface of the engagement wall 162 is swung in a predetermined direction (for example, a horizontal direction) in order to prevent the swinging arm 140 from swinging around the swinging axis O2 while allowing the swinging arm 140 to move in the front-rear direction. A blocking surface 162y (rocking blocking portion; lock mechanism) is formed.

  In addition, an arc shape that is notched at a predetermined angle (for example, 90 °) in the circumferential direction at both ends in the axial direction of the cylindrical swing shaft 142 (swing axis O2) (a range in contact with the engagement wall portion 162). A (fan-shaped) notch 142a (lock portion; lock mechanism) is formed. The notch 142a includes a first abutment surface 142x (movement obstruction; lock mechanism) that engages with the movement prevention surface 162x of the engagement wall 162, and a second abutment surface 142y that engages with the oscillation prevention surface 162y. (Swing prevention part; lock mechanism). The angle formed by the movement preventing surface 162x and the rocking preventing surface 162y is set to be equal to (for example, 90 °) the angle formed by the first contact surface 142x and the second contact surface 142y. In addition, the lower surface (swing prevention surface 162y) of the engaging wall portion 162 is positioned below the lower surface of the ceiling wall portion 164, and forms a step in the vertical direction. Further, the lower surface of the ceiling wall portion 164 is in contact with the cylindrical rocking shaft 142 from above to move the cylindrical rocking shaft 142 in the front-rear direction and rotate (swing) around the rocking axis O2. keeping.

  Also in this case, in order to assemble the swing arm 140 to the casing 6, the cylindrical swing shaft 142 has a bag shape (pocket shape) formed by the bottom wall portion 160, the front wall portion 161 and the engagement wall portion 162. Is inserted from the opening on the rear side (so as to be embedded in the hook-shaped engagement wall 162). Then, after the cylindrical rocking shaft 142 is inserted, the rocking shaft housing portion is closed by the rear wall portion 163 by covering the upper case body 6U. In this way, the cylindrical rocking shaft 142 is housed so as to be movable back and forth and rocked by being surrounded by the bottom wall 160, the front wall 161, the engagement wall 162, the rear wall 163, and the ceiling wall 164. A pair of left and right closed pivot shaft accommodating spaces S are formed.

  Thus, the back and forth movement and rotation (swing) of the cylindrical swing shaft 142 can be reliably held by the swing shaft housing portion and the rear wall portion 163 and further by the ceiling wall portion 164. Further, in the swinging shaft accommodation space S, the cylindrical swinging shaft 142 slides back and forth on the bottom wall portion 160 and swings around the swinging axis O2, so that the swinging arm 140 and the winning door 10 are moved. Even if the overall size is not reduced, the structure of the special winning device 104 can be reduced in size. Further, the first contact surface 142x of the notch portion 142a is engaged with the movement prevention surface 162x of the engagement wall portion 162, and the second contact surface 142y is engaged with the oscillation prevention surface 162y. The configuration is simplified, and the manufacturing cost can be reduced due to the simplification and size reduction of the prize winning device 104 and the reduction in the number of parts and the number of assembly steps.

  Next, the operation of the special winning device 104 having the above-described configuration will be described with reference to FIGS.

<Normal state = closed position> (FIG. 13)
In the normal state (non-big hit state), the solenoid 20 is demagnetized, the compression coil spring 23 biases the plunger 21 toward the protruding position, and holds the winning door 10 in the closed position. Specifically, when the plunger 21 of the solenoid 20 moves forward from the retracted position (FIG. 13) to the intermediate position (FIG. 12), the engagement pin 31 of the head cover 30 is not provided with the first notch recess 41 of the swing arm 140. However, since the swing arm 140 (cylindrical swing shaft 142) is prevented from moving forward by the movement blocking surface 162x of the engagement wall 162, the swing wall 140 swings at the rear wall 163. It rotates clockwise (broken arrow direction) in FIG. 13 around the axis O2. As a result, the winning door 10 rotates counterclockwise (in the direction of the broken line arrow) in FIG. 13 around the rotation axis O1, and the large winning opening 5a is closed.

  Subsequently, when the plunger 21 moves forward from the intermediate position (FIG. 12) to the protruding position (FIG. 11), the engagement pin 31 advances the first notch recess 41, so that the cylindrical swing of the swing arm 140 is performed. The shaft 142 moves forward (broken line in FIG. 12) along the ceiling wall portion 164 and the bottom wall portion 160 together with the elongated hole-like recess 32 of the head cover 30 until the first contact surface 142x of the notch portion 142a contacts the movement preventing surface 162x. The lock mechanism is activated by moving in the direction of the arrow.

<Big hit state = open position> (FIG. 13)
In the big hit state, the solenoid 20 is excited, the plunger 21 moves to the retracted position against the biasing force of the compression coil spring 23, and the winning door 10 is held in the open position. Specifically, when the plunger 21 is retracted from the protruding position (FIG. 11) to the intermediate position (FIG. 12), the engaging pin 31 retracts the first recess 41, so that the cylindrical rocking shaft 142 is retracted. Moves along the ceiling wall portion 164 and the bottom wall portion 160 together with the elongated hole-like recess 32 until it abuts against the rear wall portion 163 in FIG. 12 (in the direction of the solid line arrow), and the lock mechanism is released.

  Subsequently, when the plunger 21 is retracted from the intermediate position (FIG. 12) to the retracted position (FIG. 13), the engagement pin 31 attempts to retract the first recess 41, but the cylindrical swinging shaft 142 Since the rear wall is blocked (stopped) by the rear wall portion 163, it rotates counterclockwise (in the direction of the solid arrow) in FIG. 13 about the swing axis O2. As a result, the winning door 10 rotates clockwise (in the direction of the solid line arrow) in FIG. 13 around the rotation axis O1, and the big winning opening 5a is opened, so that the game balls flowing down the gaming area 2a are in the winning area 4a. Will be introduced.

<Locked state = closed position> (FIG. 11)
When an external force is applied to the winning door 10 to rotationally displace the winning door 10 from the closed position (FIG. 11) to the open position (FIG. 13), the second contact surface 142y of the notch 142a and the engaging wall The rocking arm 140 is prevented (locked) from rotating counterclockwise in FIG. 11 about the rocking axis O2 by the rocking prevention surface 162y (see FIG. 10) of the portion 162. Thereby, the winning door 10 is maintained in the closed position.
