Abstract

<P>PROBLEM TO BE SOLVED: To provide a prize winning device for game machines, which enables the simplification and miniaturization of its structure by: arranging a structure of combining a transmission function of drive force and a lock function against illegal outside; and making a transmission member move along the front-back direction. <P>SOLUTION: Under the jackpot state, when a plunger 21 is displaced backward to an intermediate position from its protruding position, an engaging pin 31 gets the first notched recessed part 41 retracted and so, a cylindrical rocking shaft 42 retracts with a slotlike recessed part 32 until contacting a backward stop wall part 64c. This causes a lock piece 44 to move backward along straight wall parts 61 and 62 to get a lock mechanism released. Subsequently, when the plunger 21 is displaced backward to the retraction position from the intermediate position, the engaging pin 31 forces the first notched recessed part 41 to retract, but the cylindrical rocking shaft 42 rotates around the axis O2 of its rocking because its backward movement is blocked with the backward stop wall part 64c. A prize winning door 10 turns around the axis O1 of its rotation to make a jackpot pocket 5a open. <P>COPYRIGHT: (C)2009,JPO&amp;INPIT

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 that is generally used as an “attacker” has a structure in which a rectangular large 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). . 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 (first position) that closes the big winning opening by a driving mechanism (linear actuator) such as a solenoid and a transmission mechanism such as a swing arm (transmitting member), and a front side from the closed position. Rotate and displace between the open position (second position) that falls on the side (player side) and opens the big prize opening.

  In addition, a prize winning device commonly called “Electric Chu (Electric Tulip)” has a pair of rotating wing pieces (rotating bodies) arranged between the front plate (base plate) and the front decoration part in the front-rear direction. It has a structure that rotates around an installed rotation shaft. Such a rotating blade piece is a first position that stands up to the center side and is difficult to win a prize opening by a driving means (linear actuator) such as a solenoid and a transmission mechanism such as a swing arm (transmission member). It is displaced between the (closed position) and a second position (open position) that falls from the first position outward in the left-right direction and is easy to win a winning opening.

  Since these winning devices are directly involved in paying out the prize balls, they are likely to be targets of fraud (commonly known as goto acts). For example, a foreign object such as a wire is inserted into the gaming machine, and a rotating body, a plunger of a solenoid, a transmission mechanism for transmitting power from the plunger to the rotating body, and the like are operated to forcibly bring the rotating body to the open position (second position). There is a risk that a large number of prize balls may be illegally acquired due to illegal acts of movement. Therefore, conventionally, the rotating body is configured so that the prize-winning opening is not illegally opened even if an external force that rotates the rotating body from the closed position (first position) to the open position (second position) is applied to the rotating body. A lock mechanism (security mechanism) for maintaining the position in the closed position (first position) is considered.

  At that time, the transmission mechanism is composed of a plurality of swing arms, and each swing arm has a swing axis fixed to a stationary member such as a case, and is supported only to swing around the swing axis. . Also, the lock mechanism is generally installed between these swing arms or between any of the swing arms and the rotating body so as to act separately from the transmission mechanism for power transmission (patent) Reference 1).

JP 2000-279585 A

  In such a winning device, since the front-rear position of the swing axis is fixed, the rotation angle of the rotating body is uniformly determined when the longitudinal length (full length) of the transmission mechanism is determined. If the moving angle is determined, the entire length of the transmission mechanism is also determined uniformly. Therefore, it is difficult to reduce the size of the structure unless the individual swing arms and the rotating body are reduced as a whole. In addition, since the lock mechanism is provided so as to act separately from the transmission mechanism, the lock mechanism can be arranged by selecting a part with high security in terms of security, but the number of parts is increased and the assembly process is complicated. If the structure becomes complicated and the structure is enlarged, it may become an obstacle to the effective use of the board surface (game area) of the game board.

  An object of the present invention is to provide a game in which the structure can be simplified and reduced in size by having the transmission member move back and forth, and by providing a combined function of a driving force transmission function and an improper external force locking function. An object is to provide a machine winning device 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:
The game board has a winning opening that is opened to introduce a game ball from a gaming area formed on the board surface of the gaming board to a winning area that faces the rear side opposite to the front side where the player is located. A winning device for a fixed gaming machine,
A rotating body that is displaceable between a first position where it is impossible or difficult to win a prize opening and a second position where a prize can be won or easily won by turning around a rotation axis;
By holding the driving member that is linearly displaced in the front-rear direction at the front-side protruding position and the rear-side retracted position, the rotating body is rotated about the rotation axis, and the first position and the first position are A linear actuator for displacement between two positions;
Arranged between these rotating bodies and linear actuators, allowing linear displacement in the front-rear direction accompanying movement of the drive member and swing displacement around the swing axis extending in parallel with the game board A transmission member,
A swing preventing portion that is disposed between the fixed side member and the transmission member and that prevents the transmission member from moving in the front-rear direction and prevents swinging around the swing axis; and swinging of the transmission member A lock mechanism including a movement blocking unit that allows movement in the front-rear direction while allowing swinging around the axis,
When the driving member moves from the protruding position to the retracted position and rotationally displaces the rotating body from the first position to the second position, the driving member starts from the protruding position and moves to an intermediate position between the protruding position and the retracted position. Due to the preceding movement, the transmission member is moved rearward along the rocking prevention portion, and the movement member is moved around the rocking axis by the subsequent movement from the intermediate position to the retracted position of the end point. While rotating in one direction with
When the drive member moves from the retracted position to the protruding position and rotationally displaces the rotating body from the second position to the first position, the movement is performed by a preceding operation starting from the retracted position and reaching the intermediate position. In the blocking portion, the transmission member is rotated in the other direction around the swing axis, and the transmission member is moved forward along the swing blocking portion by a subsequent operation from the intermediate position to the protruding position of the end point. It is characterized by that.

In addition, when applied to a large winning device (attacker)
The rotating body is arranged so as to be rotatable around a rotation axis extending in the left-right direction in parallel with the game board, and by standing along the game board, the winning opening is closed and the game ball is introduced into the winning area. A winning door that is displaceable between a first position that is disabled and a second 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. it can.

  In these award winning devices for gaming machines, the transmission member (the swing axis thereof) moves back and forth without reducing the transmission member (for example, the swing arm) or the rotating body (for example, the winning door) as a whole. Even if the length (full length) of the transmission member is the same, the rotation angle of the rotating body can be increased, or the total length of the transmission member can be shortened even if the rotation angle of the rotation body is equal. It becomes easy.

  Further, the transmission member disposed between the rotating body and the linear actuator (for example, a linear drive type solenoid) includes a rocking prevention unit and a movement prevention unit between the fixed side member (for example, the case). Is arranged. The transmission member and the lock mechanism (the rocking prevention unit and the movement prevention unit) include a driving force transmission function by connecting the rotating body and the linear actuator directly or indirectly through another member, and an unauthorized function. It has a structure that doubles as a lock function against external force. Therefore, with this dual-use configuration, the driving force transmission function and the locking function against unauthorized external force can be stably demonstrated, and the increase in the number of parts and assembly man-hours can be suppressed to simplify and downsize the winning device. As a result, the board surface (game area) of the game board can be used effectively.

  In addition, in the prize winning device (attacker), if the swing axis of the transmission member is arranged parallel to the rotation axis of the rotating body and orthogonal to the movement axis (for example, the plunger axis) of the drive member, the transmission member Can be smoothly moved back and forth and rocked, and the transmission function of the driving force is further stabilized.

  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. Further, the linear actuator and the transmission member can be connected via a connecting member (for example, a head cover) that is attached to the front end portion (for example, a plunger head) of the driving member and moves back and forth integrally with the driving member. In this case, the connecting member and the transmission member constitute a transmission mechanism that transmits the driving force of the linear actuator to the rotating body.

  Therefore, in these winning devices, when an external force is applied to the rotating body to rotate and displace the rotating body from the first position to the second position, the rocking prevention portion of the lock mechanism acts as the rocking axis of the transmission member. The rotation to the one direction side around can be prevented.

  Thus, unless the drive member moves from the projecting position to the intermediate position and moves the transmission member backward along the rocking prevention portion, the transmission member prevents rocking in one direction around the rocking axis. Therefore, the rocking prevention part has a function of locking against an unauthorized external force.

  Further, when the drive member moves between the projecting position and the intermediate position, a movement guide unit for guiding the movement of the transmission member in the front-rear direction and stopping the movement of the transmission member at the projecting position and the intermediate position, respectively. May be formed integrally with the stationary member.

  In addition to the lock mechanism (swing prevention part and movement prevention part), by providing such a movement guide part on the fixed side member, the preceding operation and the subsequent operation of the drive member described above can be performed by the transmission member moving back and forth. It can be clearly divided into oscillations and transmitted. Therefore, the operation of the transmission member can be smoothly linked according to the operation of the drive member.

  Further, the rocking prevention portion and the movement prevention portion of the lock mechanism are each formed integrally with the fixed side member, and the lock portion integrally formed with the transmission member may be engaged with the rocking prevention portion and / or the movement prevention portion. it can.

  In this way, the lock portion integrally formed with the transmission member engages with the rocking prevention portion and the movement prevention portion integrally formed with the stationary member, thereby simplifying the configuration of the lock mechanism and the winning device. In addition to simplification and miniaturization, it is possible to reduce the manufacturing cost by reducing the number of parts and the number of assembly steps.

  Specifically, the lock part moves in parallel (plunger movement direction) with the movement axis (plunger axis) of the drive member while engaging with the rocking prevention part, and the rocking axis while engaging with the movement prevention part. By rotating around, the lock mechanism operates smoothly, and the driving force of the driving member is accurately transmitted to the rotating body. For example, the lock part may be formed of a lock piece that can slide along a rocking prevention part and a movement prevention part that are integrally formed with each other, or a circle formed on the whole or part of the axial direction of the rocking shaft. It can be constituted by arc-shaped (fan-shaped) notches.

By the way, the fixed side member includes a base plate which has a winning opening and is fixed to the board surface of the game board,
In the base plate, an insertion hole penetrating in the front-rear direction is formed adjacent to the winning opening,
When the rotating body is in the first position, the shaft-like unlocking tool is inserted into the insertion hole from the front side so as to penetrate the base plate and the game board, and the tip of the unlocking tool presses the transmission member. By moving backward along the rocking prevention portion, the locked state of the lock mechanism can be released and the rotational displacement of the rotating body from the first position to the second position can be made possible.

  In general, there are the following circumstances in amusement stores. For example, if you win a promising jackpot just before closing the store, the game will move to a promising change state (the probability of winning is a high probability) after the jackpot ends, and the next jackpot occurrence is almost fixed. In some cases, the player is compensated for the game. By inserting a shaft-like unlocking tool into the insertion hole formed in the base plate, it is possible for the game store clerk to unlock the locking mechanism, and it is easy to compensate for the occurrence of balls when the jackpot is about to close Yes. Moreover, since the insertion hole penetrates in the front-rear direction (for example, a direction that coincides with the front-rear movement direction of the lock part of the transmission member), the transmission member (the lock part thereof) can be simply inserted into the insertion hole. Can be pressed, skill is not required for the unlocking operation, and the unlocking tool is not easily broken.

  Specifically, the unlocking tool can be constituted by a single unlocking pin. For example, the locking piece can be pushed by the unlocking pin, or the swing shaft with the notch can be pushed.

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.

  As described above, the transmission member (for example, the swinging arm) moves back and forth, and the structure for combining the transmission function of the driving force and the locking function against an unauthorized external force makes it possible to simplify and downsize the winning device. It is possible to easily achieve a gaming machine having an interesting board surface configuration.

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. FIG. 2 is a diagram showing a big winning device that is an example of a winning device according to the present invention. FIG. 3 is an exploded perspective view of the whole perspective view, with the base plate omitted and partially broken. 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, between the liquid crystal display unit 3 and the grand prize winning device 4, a start winning device 7 (winning device) configured by an electric tulip (electric chew) is arranged.

  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 big winning opening 5a (winning opening) (see FIG. 4). 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 FIGS. 6 and 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 (fixed side member) and a lower case body 6D (fixed side member). Both the case bodies 6U and 6D are integrated, and one of the case bodies (for example, the upper side body) The case body 6U) is fixed to the base plate 5.

  The big winning device 4 is arranged so that the winning door 10 (rotating body) arranged corresponding to the big winning opening 5a (see FIG. 1) and the plunger 21 (driving member) are linearly displaced in the front-rear direction. A linear drive type solenoid 20 (linear actuator), and a transmission mechanism 50 disposed between the winning door 10 and the solenoid 20 for transmitting the driving force of the plunger 21 to the winning door 10. 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 FIG. 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 (see FIG. 1). 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 pivotally supported on the base plate 5 (see FIG. 1). In this way, the winning door 10 stands along the game board 2 so as to close the large winning opening 5a and make it impossible to introduce the game ball into the winning area 4a (see FIGS. 6 and 7). (First position; see FIGS. 2 and 4) and projecting in a crossing manner to the game area 2a (see FIG. 1), it is possible to open the big prize opening 5a and introduce the game ball into the prize area 4a. It is rotationally displaced to the open position (second position; see FIGS. 6 and 7).

  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. 2 and 7). 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 lower case body 6D or the base plate 5 (refer FIG. 1) 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 includes a plunger 21 having a head portion 22 formed at a front end portion protruding from the solenoid case 29, and between the solenoid case 29 and a head cover 30 described later. And an intervening compression coil spring 23 (a resilient member). The solenoid 20 holds the head portion 22 in a forward protruding position (see FIG. 4) and a backward retracted position (see FIG. 6), thereby rotating the winning door 10 around the rotation axis O1. Then, it is displaced between a closed position (see FIG. 4) and an open position (see FIG. 6). 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 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. 4), 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 via the head cover 30 so as to displace the winning door 10 to the open position (see FIG. 6). The swing axis O2 is orthogonal to the plunger axis O3 (see FIGS. 4 to 6).

  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 (see FIGS. 4 to 6). An engagement pin 31 protruding parallel to the movement axis O2 (cylindrical rocking shaft 42) is inserted (arranged) into a first notch recess 41 of the first arm 40a described later, and the holding portion 33 is provided. It is held by the head portion 22 of the plunger 21.

  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). 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 40a (the swing arm 40) moves in the front-rear direction accompanying the movement of the plunger 21 (head cover 30) by engaging the first notch-shaped recess 41 with the engagement pin 31 protruding from the head cover 30. Linear displacement (see FIGS. 4 and 5) and rocking displacement (see FIGS. 5 and 6) around the cylindrical rocking shaft 42 (rocking axis O2). 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. 4) or opening (see FIG. 6). Can be maintained.

  Returning to FIG. 2, a lock mechanism is provided between the casing 6 (upper case body 6 </ b> U and lower case body 6 </ b> D) and the swing arm 40. This locking mechanism is directed inward from the outer peripheral walls of the upper case body 6U and the lower case body 6D in order to prevent the swing arm 40 from swinging around the swing axis O2 while allowing the swing arm 40 to move in the front-rear direction. The pair of upper and lower linear wall portions 61 and 62 (swing prevention portions) that are formed so as to protrude and extend in the front-rear direction at predetermined intervals, and swinging around the swing axis O2 of the swing arm 40 are allowed. In order to prevent movement in the front-rear direction, an arcuate curved wall portion 63 (movement prevention portion) that protrudes inward from the outer peripheral wall of the upper case body 6U is included.

  Specifically, the upper linear wall portion 61 and the curved wall portion 63 are integrally connected to the upper case body 6U in a form integrally connected. The lower linear wall portion 62 is integrally formed with the lower case body 6D. Further, a lock piece 44 (lock portion; lock mechanism) is integrally formed on the swing arm 40 (second arm 40b) so as to face the outer peripheral wall of the casing 6, and the upper straight wall portion 61 and the lower straight wall shape are formed. It slides in the front-rear direction along the wall 62 (linear movement) (see FIG. 5), and slides (rotates) along the curved wall 63 around the swing axis O2 (FIG. 6, FIG. 6). 7). Note that the lock piece 44 of the swing arm 40 is located on the extended line of the plunger axis O3 in a side view at the protruding position of the plunger 21 (head cover 30) (see FIG. 4).

  As a result, when the plunger 21 moves from the protruding position to the retracted position and pivotally displaces the winning door 10 from the closed position to the open position, the preceding operation starts from the protruding position and reaches an intermediate position between the protruding position and the retracted position. Then, the swing arm 40 (the lock piece 44) is moved rearward along the straight wall portions 61 and 62. Thereafter, by the subsequent operation from the intermediate position to the retracted position at the end point, the swing arm 40 (the lock piece 44 thereof) is moved around the swing axis O2 in one direction (counterclockwise in FIG. 6). Rotate. Specific operation will be described later.

  On the other hand, when the plunger 21 is moved from the retracted position to the projecting position to pivotally displace the winning door 10 from the open position to the closed position, the curved wall 63 ( The swing arm 40 (the lock piece 44) is rotated around the swing axis O2 in the other direction (clockwise in FIG. 6) while preventing forward movement. Thereafter, the swing arm 40 (the lock piece 44 thereof) is moved forward along the straight wall portions 61 and 62 by the subsequent operation from the intermediate position to the protruding position at the end point. Specific operation will be described later.

  Further, when an external force is applied to the winning door 10 to rotate the winning door 10 from the protruding position to the retracted position, the linear walls 61 and 62 of the locking mechanism are moved to the swing arm 40 (the locking piece of the swing arm 40). 44) is prevented from rotating in one direction (counterclockwise in FIG. 4) around the swing axis O2. Specific operation will be described later.

  Further, as shown in FIGS. 2, 3, and 7, a pair of guide portions 64, 64 (movement guide portions) that are arranged to face each other in the left-right direction are integrally formed in the lower case body 6D. When the plunger 21 (head cover 30) moves between the protruding position (see FIG. 4) and the intermediate position (see FIG. 5), the guide portion 64 has the cylindrical swing shaft 42 of the swing arm 40 in the front-rear direction. A sliding wall portion 64a (sliding portion) that slides and guides the movement to the left and right, and a hook-like shape that protrudes from the front and rear end portions of the sliding wall portion 64a toward the opposite side. It includes a front-side stop wall portion 64b (front-side stop portion) and a rear-side stop wall portion 64c (rear-side stop portion) that stop the movement of the cylindrical swing shaft 42 at each position.

  In addition to the lock mechanism (the straight wall portions 61 and 62, the curved wall portion 63 and the lock piece 44), the above-described plunger 21 (head cover 30) is provided by providing such a guide portion 64 in the lower case body 6D. The preceding operation and the subsequent operation are transmitted in distinctly divided into the longitudinal movement and the swing of the cylindrical swing shaft 42 of the swing arm 40. Therefore, the operation of the swing arm 40 (cylindrical swing shaft 42) is smoothly linked according to the operation of the plunger 21 (head cover 30). The curved wall 63 constitutes a forward movement blocking portion (lock mechanism), whereas the rear stop wall 64c also serves as a backward movement blocking portion (lock mechanism).

  As shown in FIGS. 1 and 8, the base plate 5 has a plunger axis line O3 adjacent to the big prize opening 5a in the front-rear direction (that is, in the direction coinciding with the front-rear movement direction of the lock piece 44 of the swing arm 40). The insertion hole 5b is formed so as to penetrate in parallel. By inserting the lock release pin 300 into the insertion hole 5b, the lock state of the lock mechanism is released.

  Next, using FIG. 4 to FIG. 6 and FIG. 8, the operation of the special winning device 4 having the above-described configuration will be described.

<Normal state = closed position> (FIG. 4)
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. 6) to the intermediate position (FIG. 5), the engagement pin 31 of the head cover 30 is not provided with the first notch recess 41 of the swing arm 40. However, since the lock piece 44 of the swing arm 40 is prevented from moving forward by the curved wall portion 63, the lock piece 44 is moved along the curved wall portion 63 around the swing axis O <b> 2. 6 rotates clockwise (in the direction of the broken line arrow). As a result, the winning door 10 rotates counterclockwise (in the direction of the broken arrow) in FIG. 6 around the rotation axis O1, and the special winning opening 5a is closed.

  Subsequently, when the plunger 21 moves forward from the intermediate position (FIG. 5) to the protruding position (FIG. 4), the engagement pin 31 advances the first notch recess 41, so that the cylindrical swing of the swing arm 40 is performed. The shaft 42 moves forward with the elongated hole-shaped recess 32 of the head cover 30 until it abuts against the front stop wall 64b, and the lock piece 44 moves forward (in the direction of the broken arrow) along the straight walls 61 and 62 in FIG. Then, the lock mechanism is activated.

<Big hit state = open position> (FIG. 6)
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 moves backward from the protruding position (FIG. 4) to the intermediate position (FIG. 5), the engaging pin 31 retracts the first recess 41, so that the cylindrical rocking shaft 42 is moved. Retreats together with the long hole-like recess 32 until it abuts against the rear stop wall 64c, and the lock piece 44 moves rearward (in the direction of the solid arrow) in FIG. Is released.

  Subsequently, when the plunger 21 is retracted from the intermediate position (FIG. 5) to the retracted position (FIG. 6), the engagement pin 31 attempts to retract the first notch recess 41, but the cylindrical rocking shaft 42 is moved. 6 is prevented (stopped) from moving backward by the rear stop wall 64c, so that the counterclockwise rotation in FIG. 6 centering on the swing axis O2 (in the form in which the lock piece 44 follows the curved wall 63). Rotate in the direction of the solid arrow. As a result, the winning door 10 rotates clockwise (in the direction of the solid line arrow) in FIG. 6 around the rotation axis O1, and the large 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. 4)
When an external force is applied to the winning door 10 to rotate the winning door 10 from the closed position (FIG. 4) to the open position (FIG. 6), the lock piece 44 of the swing arm 40 and the upper and lower linear walls. The portions 61 and 62 prevent (lock) the swing arm 40 from rotating counterclockwise in FIG. 4 about the swing axis O2. Thereby, the winning door 10 is maintained in the closed position.

<Unlocked state> (Fig. 8)
When the winning door 10 is in the closed position, when the game store clerk inserts the unlocking pin 300 into the insertion hole 5b of the base plate 5 in order to compensate for the withdrawal (FIG. 8A), the tip of the unlocking pin 300 is inserted. The portion presses the locking piece 44 of the swing arm 40 and moves to the rear intermediate position along the upper and lower linear wall portions 61 and 62 (FIG. 8B). By disengaging the lock piece 44 from the upper and lower linear wall portions 61, 62, the swing prevention state of the swing arm 40 is released. The game ball can be introduced into the winning area 4a by rotating the position from the position to the open position (FIG. 8C).

  As described above, the swing axis O2 (cylindrical swing shaft 42) of the swing arm 40 moves back and forth, whereby the structure of the big winning device 4 can be greatly reduced in size. Further, between the swing arm 40 and the casing 6, upper and lower linear wall portions 61 and 62 (swing prevention portion), a curved wall portion 63 and a rear side stop wall portion 64 c (movement prevention portion) are included. A lock mechanism is arranged, and the swing arm 40 and the lock mechanism have a configuration that serves as both a driving force transmission function and an improper external force locking function. Such a dual-use configuration stably exhibits a driving force transmission function and an improper external force locking function, and suppresses an increase in the number of parts and assembly man-hours, thereby simplifying and reducing the size of the winning device 4. Therefore, the board surface (game area 2a) of the game board 2 can be effectively utilized.

  Further, unless the plunger 21 (head cover 30) moves from the protruding position to the intermediate position and the lock piece 44 of the swing arm 40 is moved rearward along the upper and lower linear wall portions 61, 62, the swing arm 40 does not swing. The rotation around the movement axis O <b> 2 is blocked by the linear walls 61 and 62. As a result, the straight wall portions 61 and 62 can reliably perform a locking function against an unauthorized external force. In addition, since the lock function can be easily released simply by inserting the lock release pin 300 into the insertion hole 5b and pressing the lock piece 44 of the swing arm 40, the locked state when performing ball exit compensation or the like is achieved. The unlocking operation does not require skill and the lock release pin 300 is not easily broken.
