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 having a longitudinal direction on the left and right 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. Such a winning door includes a closed position that closes the big winning opening by a driving means (linear actuator) such as a solenoid and a transmission mechanism such as a swing arm (transmitting member), and a front side (player side) from the closed position. ) To the open position where the big prize opening is opened.

  Such a winning device is directly involved in paying out a prize ball, and thus 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, conventionally, a lock is used to keep the winning door in the closed position so that the large winning opening is not improperly opened even if an external force is applied to the winning door to rotate and displace the winning door from the closed position to the open position. Mechanism (security mechanism) is considered.

  At that time, the transmission mechanism is composed of a plurality of transmission members, and the lock mechanism is separated between the transmission members or between any of the transmission members and the winning door, in addition to the interlocking means (interlocking mechanism) for power transmission. It is common to install (refer patent document 1). Also, in a winning device commonly referred to as “electric chew” and having a pair of opening and closing members (rotating blade pieces), a solenoid arm (drive transmission member) for transmitting power from the plunger to the opening and closing member is a plunger in a closed state of the opening and closing member. A mechanism that directly engages and locks the head portion of the head is disclosed (see Patent Document 2).

JP 2000-279585 A JP 2003-340020 A

  Among these, in the former (Patent Document 1), since the lock mechanism is provided separately from the interlocking means, it is possible to select the part with high security in terms of crime prevention and arrange the lock mechanism, but the structure is complicated. It becomes easy to increase the size, which may be an obstacle to the effective use of the board surface (game area) of the game board. On the other hand, in the latter (Patent Document 2), the drive transmission member for power transmission also serves as a lock mechanism, so that the structure can be simplified and miniaturized. However, when an improper external force is applied to the winning door, the drive is performed. Since the rotational force of the transmission member is directly transmitted to the head portion of the plunger, the plunger is liable to be twisted, and there is a possibility of causing damage such as bending or bending of the plunger.

  An object of the present invention is to provide a combination of a driving force transmission function and an improper external force locking function between a connecting member connected to a driving member of a linear actuator and a transmission member connected to a prize door. Accordingly, it is an object of the present invention to provide a gaming machine winning device capable of simplifying and downsizing the structure and preventing damage to a driving member and a gaming machine using the same.

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:
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 prize-winning device for a gaming machine having a prize 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 drive door that is linearly displaced in the front-rear direction is held at the front-side protruding position and the backward-side retracted position on one end side in the left-right direction of the winning opening, so that the winning door is moved around the rotation axis. A linear actuator that is rotated to displace between the closed position and the open position;
A connecting member attached to the front end of the driving member and moving back and forth integrally with the driving member;
The swing door is disposed between the winning door and the linear actuator, and is arranged in parallel with the pivot axis behind the pivot axis, and alternatively with the engaging portion of the connecting member. A contact portion including a pair of contact surfaces that can contact the contact portion, and a transmission member that engages with the engagement portion,
The engagement portion of the connecting member and the contact portion of the transmission member are the first and second contact surfaces when the connection member moves from the protruding position to the retracted position. The transmission member rotates in one direction as it shifts to the contact state with the two contact surfaces, and the winning door is rotated and displaced from the closed position to the open position, while the connecting member is in the retracted position. When the engagement portion moves from the contact state with the second contact surface to the contact state with the first contact surface, the transmission member rotates in the other direction. And constituting a transmission mechanism for rotationally displacing the winning door from the open position to the closed position,
The first contact surface of the contact portion of the transmission member and the engagement portion of the connecting member are subjected to an external force that rotates the winning door from the closed position to the open position. And a locking mechanism for preventing the transmission member from rotating in one direction.

  In the above gaming machine, driving is performed between a connecting member (for example, a head cover) connected to a driving member (for example, a plunger) of a linear actuator (for example, a solenoid) and a transmission member (for example, a swing arm) connected to a winning door. It has a structure that doubles as a force transmission function and a lock function against unauthorized external force. That is, the driving force is transmitted by the contact between the first contact surface and the second contact surface of the contact portion of the transmission member and the engagement portion (for example, the engagement pin) of the coupling member, and the contact force of the transmission member is reduced. The first contact surface of the contact portion and the engaging portion of the connecting member are locked (rotation prevention) against an improper external force. Thus, the first abutment surface and the engaging portion serve both as a driving force transmission function and an improper external force locking function. Therefore, simplification and downsizing of the structure can be achieved by the dual configuration. Further, even if an improper external force is applied to the winning door, the turning force of the transmission member is not directly transmitted to the drive member, so that the drive member is not easily twisted, and the drive member can be prevented from being bent or broken.

  Note that a linear drive solenoid plunger is generally used as a drive member of the linear actuator, but a drive output shaft of a linear stepping motor or the like may be used, for example.

Specifically, when viewed from the swing axis direction, the first contact surface and the second contact surface face each other at a predetermined crossing angle so that the contact portion is a part of the outer peripheral edge of the transmission member. Formed in a notch having an opening opened to the front side by removing the part,
The engaging portion of the connecting member can be disposed (for example, inserted) in the cutout portion so as to protrude in the swing axis direction.

  As a result, the simplification and downsizing can be further achieved, and the engaging portion only needs to be arranged in the notch portion, so that the assembling property can be improved and the manufacturing cost can be reduced.

  At this time, the crossing angle α between the first contact surface and the second contact surface is larger than the swing angle β of the transmission member when the winning door rotates between the closed position and the open position, (Rocking angle β ≦ intersection angle α ≦ 90 °).

  By setting the swing angle β ≦ the crossing angle α, the amount of movement of the engaging portion within the notch portion can be relatively large. As a result, the pivot angle of the winning door with respect to the swing angle β of the transmission member β ′ can be increased (swing angle β ≦ rotation angle β ′), and the transmission mechanism can be further downsized. Note that, by setting the crossing angle α ≦ 90 °, it is possible to prevent the engaging portion of the connecting member from being detached (disengaged) from the notch opening of the transmission member when the transmission member swings.

  In addition, the first contact surface is positioned below the engaging portion of the connecting member, and is formed so as to be an inclined surface that becomes lower as the horizontal surface or the rear side when the connecting member moves to the protruding position, Is added to the winning door, it can be brought into contact with the engaging portion of the connecting member from the lower side to prevent the transmission member from rotating.

  In this way, the first abutment surface of the transmission member abuts the engaging portion of the connecting member from the lower side, so that an improper external force is applied to rotate the winning door from the closed position to the open position. Sometimes, it becomes easy to prevent the unauthorized external force from rotating the transmission member in one direction and moving the engaging portion of the connecting member from the protruding position to the retracted position.

  When the inclination angle γ formed by the inclined surface and the horizontal plane is set to 45 ° or less (inclination angle γ ≦ 45 °), the engaging portion of the connecting member is moved from the protruding position to the retracted position out of the above-described unauthorized external force. The horizontal component force to be moved to becomes smaller than the vertical component force to lift and move the engaging portion of the connecting member upward. Thus, the award opening of the winning door can be reliably prevented by the contact between the first contact surface of the transmission member and the engaging portion of the connecting member.

  Furthermore, the head portion of the plunger can be connected to the connecting member so as to be rotatable around its own longitudinal axis.

  Since the plunger is rotatably connected to the coupling member, even if the above-described unauthorized external force acts as the bending force or torsional force of the plunger, the plunger is released by the relative rotation of the coupling member and the head portion. Can be avoided, and damage such as bending or bending of the plunger can be more reliably prevented.

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

  Thus, between the connecting member (head cover) connected to the driving member (plunger) of the linear actuator (solenoid) and the transmitting member (swinging arm) connected to the winning door, By providing a configuration that can be combined with a lock function against unauthorized external force, the prize winning device can be simplified and reduced in size, and the driving member can be prevented from being damaged, so that an amusement machine having an interesting board surface configuration can be easily realized. Can do.

Example 1
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view illustrating a pachinko machine equipped with a winning device for gaming machines (hereinafter also simply referred to as a winning device) according to the present invention, and FIG. 2 is a partially broken view showing an example of the winning device according to the present invention. FIG. 3 is an exploded perspective view of the main part. As shown in FIG. 1, on the board surface 2a (front surface) of the game board 2 of the pachinko machine 1 (game machine), a substantially left half circumference is partitioned by two inner and outer firing rails 2b, and a circular game area 2c as a whole is formed. Is formed. A liquid crystal display unit 3 is mounted in the center of the game area 2c, and a winning device 4 (large winning device) is disposed below the liquid crystal display unit 3 (lower center of the game area 2c). An electric tulip (hereinafter also referred to as an electric chew) 6 having a start winning opening and formed by a pair of rotating blades (not shown) is provided between the liquid crystal display unit 3 and the winning device 4. Has been placed.

  The winning device 4 includes a base plate 5 for fixing to the game board 2. The base plate 5 is formed to penetrate in the thickness direction (front-rear direction), and has a rectangular shape that opens in the up-down direction in the flow direction in the game area 2c and in the left-right direction that is the intersecting (for example, orthogonal) direction as the longitudinal direction. It has a winning opening 5a (large winning opening; see FIG. 4). Therefore, a game ball (not shown) launched from the launch rail 2b passes from the game area 2c formed on the board surface 2a of the game board 2 through the prize opening 5a and the rear prize area 5b (see FIG. 4). ).

  In the present specification, the vertical direction means a direction (for example, a vertical direction) in which the game ball flows down along the board surface 2 a of the game board 2. Further, the left and right direction means a direction (for example, a horizontal direction) intersecting with the up and down direction along the board surface 2a 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.

  As shown in FIG. 2, the winning device 4 includes a winning door 10 (large winning door) attached to the base plate 5 (see FIG. 1) corresponding to the winning opening 5a (see FIG. 4), and a plunger 21 in the front-rear direction. A linear drive type solenoid 20 (linear actuator) arranged so that the (drive member) is linearly displaced, and the driving force of the plunger 21 arranged between the winning door 10 and the solenoid 20 is transmitted to the winning door 10. The transmission mechanism 50 is provided. The winning door 10, the solenoid 20, and the transmission mechanism 50 are accommodated in a front case 4 a and a rear case 4 b made of a polymer material (for example, synthetic resin) and assembled to the base plate 5. The front case 4a and the rear case 4b also accommodate a proximity switch (a winning ball detector) for detecting a winning ball to the winning device 4, a light emitting substrate for illuminating the inside of the winning device 4, and the like. In both cases, the illustration is omitted.

  As shown in FIG. 3, the winning door 10 has a rectangular plate shape whose longitudinal direction is the longitudinal direction when viewed from the front, and is fitted into the winning opening 5 a (see FIG. 4), for example, the game board 2 (FIG. 1) and is arranged so as to be rotatable around a rotation axis O1 extending along the lower side of the winning opening 5a. Then, by standing along the game board 2, the winning opening 5 a is closed to make it impossible to introduce the game ball into the winning area 5 b (see FIG. 4), and the gaming area 2 c ( By projecting in a crossing manner to FIG. 1), the winning opening 5a is opened, and the position is turned to an open position (see FIG. 7) that allows the game ball to be introduced into the winning area 5b.

  Specifically, the winning door 10 is provided with rotating shafts 11 and 11 projecting left and right along the rotation axis O1 at the lower ends of both sides, and the rotating shafts 11 and 11 are provided on the front case 4a. It is rotatably supported (see FIG. 4). In addition, it is good also as a form which forms a shaft hole instead of the rotating shafts 11 and is pivotally supported from the front case 4a 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 from the left end surface outward in parallel with the rotation axis O1. 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).

  The solenoid 20 is disposed in the front-rear direction at the left end portion of the winning door 10, and is disposed between a plunger 21 having a head portion 22 formed at a front end portion protruding from the main body case 29, and a main body case 29 and a head cover 30 described later. And an intervening compression coil spring 23 (a resilient member). The solenoid 20 rotates the winning door 10 around the rotation axis O <b> 1 by holding the head portion 22 in a forward protruding position (see FIG. 5) and a backward retracted position (see FIG. 7). Then, it is displaced between a closed position (see FIG. 5) 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. Thereby, the plunger 21 (head part 22) is hold | maintained (connected) rotatably with respect to the holding | maintenance part 33 around the plunger axis line O3 of the front-back direction (refer FIG. 4).

  Next, the transmission mechanism 50 is arrange | positioned in the front-back direction along the plunger axis line O3 direction in the left end part 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) that swings around a swing axis O2 arranged in parallel with O1 and that engages with the head cover 30. 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. 5), 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 is orthogonal to the plunger axis O3 (see FIG. 4).

  The swing arm 40 is formed in a substantially L shape, and is connected to the head cover 30 and swings about a cylindrical swing shaft 42 (swing axis O2) as the plunger 21 moves back and forth. (First swinging part) and a second arm 40b (second swinging part) that can contact (engage) the winning door 10 behind the rotation axis O1. The second arm 40b is formed with a notch-shaped recess 43 that can maintain the winning door 10 in the closed position or the open position by engaging with the protrusion 13 of the side wall 12 on the rear side of the rotation axis O1. Has been.

  As shown in FIG. 4, the first arm 40 a has an opening opened to the front side by removing a part of the outer peripheral edge, and is selected from an engagement pin 31 (engagement portion) protruding from the head cover 30. A pair of contact surfaces 41a and 41b that can be contacted with each other is substantially V-shaped, and a notch 41 (contact portion) is formed. Among these, the 1st contact surface 41a located under the engaging pin 31 is formed horizontally in the closed position (projecting position of the head cover 30) of the winning door 10 shown in FIG. On the other hand, the second abutment surface 41b is disposed opposite to the first abutment surface 41a across the crossing angle α (see FIG. 5), and is formed in a vertical shape at the open position of the winning door 10 (the retracted position of the head cover 30). (See FIG. 7). Here, an intersection angle α (for example, 65 °; see FIG. 5) between the first contact surface 41a and the second contact surface 41b is determined when the winning door 10 rotates between the closed position and the open position. The swing arm 40 is formed to be larger than a swing angle β (for example, 30 °; see FIG. 7) and smaller than a right angle (swing angle β ≦ intersection angle α ≦ 90 °).

  In this way, by setting the swing angle β ≦ the crossing angle α, the amount of movement of the engagement pin 31 in the notch 41 can be relatively large. As a result, the swing angle β of the swing arm 40 is increased. In contrast, the rotation angle β ′ (for example, 50 °; see FIG. 7) of the winning door 10 can be increased (swing angle β ≦ rotation angle β ′), and the transmission mechanism 50 can be downsized. . By setting the crossing angle α ≦ 90 °, it is possible to prevent the engagement pin 31 of the head cover 30 from being detached (detached) from the opening of the notch 41 of the swing arm 40 when the swing arm 40 swings. .

  The head cover 30 is parallel to the swing axis O2 (cylindrical swing shaft 42) while sliding and guiding the cylindrical swing shaft 42 of the first arm 40a by the elongated hole-shaped recess 32 (see FIGS. 5 to 7). The engaging pin 31 protruding in a shape is inserted (arranged) into the cutout portion 41 of the first arm 40a in such a manner that the engaging pin 31 can selectively contact the pair of contact surfaces 41a and 41b, and the holding portion 33 and the head portion 22 of the plunger 21 are relatively rotatably held. The plunger 21 (head portion 22) is connected to the holding portion 33 so as to be rotatable around the plunger axis O3, and the holding portion 33 (head cover 30) is held on the cylindrical rocking shaft 42 by the elongated hole-like recess 32. Thus, the holding portion 33 itself is also connected to the plunger 21 (head portion 22) so as to be rotatable around the plunger axis O3. Therefore, even if an improper external force that attempts to rotationally displace the winning door 10 from the closed position to the open position acts as a bending force or a twisting force of the plunger 21, the relative rotation between the holding portion 33 and the head portion 22. Can escape (avoid twisting), and can prevent the plunger 21 from being bent or broken.

  Among the head cover 30 and the swing arm 40, the engagement pin 31 in the head cover 30 and the notch 41 in the swing arm 40 constitute the main part of the transmission mechanism 50. Specifically, when the head cover 30 moves from the protruding position to the retracted position (see FIGS. 5 to 7), the elongated hole-shaped recess 32 of the head cover 30 moves backward while sliding the cylindrical swing shaft 42, The engagement pin 31 of the head cover 30 moves rearward on the first contact surface 41a of the notch 41 (see FIG. 6). Next, the first arm 40a moves in one direction (counterclockwise) as the engagement pin 31 moves away from the contact state with the first contact surface 41a and shifts to the contact state with the second contact surface 41b. The winning door 10 is pivotally displaced from the closed position to the open position (see FIG. 7). At this time, the upper surface of the notch-shaped recess 43 of the second arm 40b presses and holds the protruding portion 13 of the side wall portion 12 from above to maintain the winning door 10 in the open position.

  On the other hand, when the head cover 30 moves from the retracted position to the protruding position (see FIG. 7 → FIG. 5), the elongated hole-shaped recess 32 of the head cover 30 moves forward while sliding the cylindrical rocking shaft 42, and the head cover 30 The engagement pin 31 also moves forward from the second contact surface 41b of the notch 41 (see FIG. 6). Next, as the engagement pin 31 moves away from the contact state with the second contact surface 41b and shifts to the contact state with the first contact surface 41a, the first arm 40a moves in the other direction (clockwise). By rotating, the winning door 10 is rotationally displaced from the open position to the closed position (see FIG. 5). At this time, the upper surface of the notch-shaped recess 43 of the second arm 40b presses and holds the protruding portion 13 of the side wall portion 12 from above to maintain the winning door 10 in the closed position.

  In the cutout portion 41 of the swing arm 40, the converging portion (V-shaped pointed portion) between the first contact surface 41a and the second contact surface 41b having a substantially V shape has a substantially semicircular shape. A groove 41c is formed by a rounded surface or the like. Since the V-shaped pointed portion is removed by the formation of the groove 41c, when the engagement pin 31 moves between the first contact surface 41a and the second contact surface 41b, the V-shape of the notch 41 is formed. It is possible to prevent the engagement pin 31 from being locked at the pointed end and becoming immovable.

  Next, the assembly procedure of the winning device 4 will be outlined with reference to FIGS. First, the head portion 22 of the plunger 21 is inserted into the holding portion 33 of the head cover 30. Subsequently, the long hole-like recess 32 of the head cover 30 and the cylindrical rocking shaft 42 of the rocking arm 40 are fixed so as to protrude from the fixing plate 4c made of a polymer material (for example, synthetic resin) along the rocking axis O2. The solenoid 20 (main body case 29) is placed and fixed on the fixing plate 4c by a shaft 4d and a fastening member 4f such as a screw. Thereafter, with the solenoid 20, the head cover 30, and the swing arm 40 held by the fixed plate 4c, the fixed plate 4c is inserted from the rear case 4b into the front case 4a.

  At this time, the notch-like recess 43 of the swing arm 40 is engaged with the protrusion 13 of the winning door 10 whose pivot shaft 11 is rotatably supported by the recess 4a1 of the front case 4a at the front end. Further, in the intermediate portion, the fixing shaft 4d of the fixing plate 4c is fitted and fixed to the recess 4b1 formed on the inner surface of the rear case 4b. Further, at the rear end portion, the convex portion 4c1 of the fixing plate 4c is fitted and fixed to the claw portion 4b2 formed at the rear end of the rear case 4b using the elastic deformation of the synthetic resin. As described above, most of the winning device 4 can be assembled and unitized in advance by the fixing plate 4c, and then inserted into the cases 4a and 4b to be assembled with the winning door 10, thereby improving the efficiency of the assembling work. The manufacturing cost can be reduced, and design changes and specification changes can be handled quickly.

  Next, the operation of the winning device 4 having the above configuration will be described with reference to FIGS. 1, 4 and 5 to 7 in relation to the gaming state in the gaming area 2c.

<Normal state = closed position> (FIG. 5)
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 is displaced from the retracted position to the protruding position, the engagement pin 31 of the head cover 30 contacts the first contact surface 41a of the notch 41, and the upper surface of the notch-shaped recess 43 is the side wall. The winning door 10 is maintained in the closed position by pressing and holding the protruding portion 13 of the portion 12 from above. Accordingly, the game balls flowing down the game area 2c are not introduced into the winning area 5b.

<Big hit state = open position> (FIG. 7)
When a game ball flowing down the game area 2c wins the electric chew 6, a winning / losing 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 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 of the solenoid 20 is displaced from the protruding position to the retracted position, the elongated hole-shaped recess 32 of the head cover 30 moves backward while sliding the cylindrical swinging shaft 42 to engage the head cover 30. The pin 31 moves to an intermediate position (FIG. 6) where the contact state with the first contact surface 41a of the notch 41 is eliminated. Thereafter, the engagement pin 31 shifts to a contact state with the second contact surface 41b, and the upper surface of the notch-shaped recess 43 presses and holds the protruding portion 13 of the side wall portion 12 from above, thereby opening the winning door 10. Keep in position. As a result, game balls flowing down the game area 2c are introduced into the winning area 5b.

  When a predetermined number (for example, 10) of winnings in the winning opening 5a is detected or when a predetermined time (for example, 30 seconds) has elapsed, the solenoid 20 is demagnetized again, and the head portion 22 of the plunger 21 is The winning door 10 is displaced from the retracted position to the projecting position, and the winning door 10 is displaced from the open position (FIG. 7) through the intermediate position (FIG. 6) to the closed position (FIG. 5). 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.

<Locked state = closed position> (FIG. 5)
When an external force is applied to the winning door 10 to rotate the winning door 10 from the closed position (FIG. 5) to the open position (FIG. 7), the first contact surface of the notch 41 in the swing arm 40 41a is in contact with the engaging pin 31 in the head cover 30 from below. Thereby, the counterclockwise rotation of the swing arm 40 is prevented, and the winning door 10 is maintained in the closed position.

  As described above, the driving force is transmitted by the contact between the first contact surface 41 a and the second contact surface 41 b of the notch 41 in the swing arm 40 and the engagement pin 31 in the head cover 30, and the notch 41. The first abutment surface 41a and the engagement pin 31 are locked (rotation blocked) against an unauthorized external force. That is, the first contact surface 41a and the engaging pin 31 serve both as a driving force transmission function and an improper external force locking function. With such a dual-use configuration, the structure can be simplified and downsized. Further, even if an improper external force is applied to the winning door 10, the turning force of the swing arm 40 is not directly transmitted to the plunger 21, so that the plunger 21 is unlikely to be twisted, and the plunger 21 can be prevented from being bent or broken.

  In the type in which the swing arm 40 is always positioned forward of the swing axis O2 and tilts clockwise by its own weight (moving the center of gravity) (so-called self-weight type), the closed position of the winning door 10 (see FIG. 5), there may be a slight gap between the first abutment surface 41a and the engagement pin 31 due to manufacturing errors and wear after the start of use. In addition, since the center of gravity of the swing arm 40 is always positioned above or behind the swing axis O2, it tilts clockwise around the swing axis O2 when a moment based on the driving force of the plunger 21 is applied ( In the so-called self-supporting type, a slight gap is generated between the second contact surface 41b and the engagement pin 31 at the open position of the winning door 10 (FIG. 7) due to manufacturing errors and wear after the start of use. There is a case.

After passing through the hole-like recess 32 and the cylindrical swing shaft 42 of the swing arm 40, the cylindrical swing shaft 42 of the swing arm 40 is rotatably supported by a fastening member 4e such as a screw.

(Example 2)
FIG. 10 is a side view for explaining the operation when the winning door is in the closed position in the winning device showing another example. FIG. 11 is a side view for explaining the operation when the winning door is between the closed position and the open position. FIG. 12 is a side view for explaining the operation when the winning door is in the open position. In the winning device 4 '(game machine winning device) shown in these drawings, the first of the notches 41 (abutting portions) located below the engaging pins 31 (engaging portions) of the head cover 30 (connecting member). The abutting surface 41a ′ is formed on an inclined surface that becomes lower toward the rear side in the closed position of the winning door 10 (projecting position of the head cover 30) shown in FIG. However, the inclination angle γ (for example, 5 °; see FIG. 10) formed by the inclined surface (first contact surface 41a ′) and the horizontal plane is set to 45 ° or less.

  As described above, since the inclination angle γ is set to 45 ° or less (inclination angle γ ≦ 45 °), the engaging pin 31 of the head cover 30 is moved from the protruding position to the retracted position out of the above-described unauthorized external forces. The horizontal component force to be smaller than the vertical component force to lift and move the engagement pin 31 upward. As described above, the award opening of the winning door 10 can be reliably prevented by the contact between the first contact surface 41 a ′ of the swing arm 40 (transmission member) and the engagement pin 31 of the head cover 30. In this embodiment, since the first contact surface 41a ′ is formed as an inclined surface, the engagement pin 31 moves between the first contact surface 41a ′ and the second contact surface 41b (particularly, During the movement from the first contact surface 41a ′ to the second contact surface 41b), the above-described locking phenomenon at the V-shaped pointed portion is unlikely to occur. Therefore, the groove 41c in the first embodiment (FIG. 4) is not formed in the cutout portion 41 of the present embodiment.

  In the modified example (FIGS. 8 and 9) and the second embodiment (FIGS. 10 to 12), the same reference numerals are given to the portions having the same functions as those in the first embodiment (FIGS. 2 to 7). Is omitted. The operation of the winning device 4 'shown in FIGS. 10 to 12 is the same as the operation of the winning device 4 shown in FIGS.
