JP5078577B2 - Game machine winning device and game machine using the same - Google Patents

Description

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

  For example, in a recent pachinko machine, in a game area formed on the front side (player side) of a game board, a variable display unit (for example, a liquid crystal display) is used to display various results such as lottery results and reach actions. In order to effectively display such effects, the center accessory and the side lamps for gaming machines are becoming larger. In addition, due to the relaxation of rules related to recent gaming machines, it has become possible to provide a plurality of start openings (start winning devices) and large winning openings (large winning devices).

  As described above, diversification of games can be achieved by increasing the size of the display unit, the accessory, and the like in the game area and adopting a plurality of start openings, prize winning openings, and the like. On the other hand, since the size of the game area is almost the same, the formation of a flow path (for example, nail arrangement) for flowing down the game balls is limited, and the game ball can flow only in a limited flow path in the game area If the flow path width becomes narrow and the game ball is likely to be clogged in the game area, the player's interest in the game is hindered. For this reason, downsizing of the winning device is attracting attention as a new request.

  By the way, a winning device generally used as an “attacker” has a structure in which a rectangular large winning opening having a left and right longitudinal direction 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 falls on a closed position that closes the large winning opening by a driving means such as a solenoid and a transmission mechanism such as a swinging arm (transmission member), and falls from the closed position to the front side (player side). It is displaced between the open position where the big prize opening is opened. And the interlocking structure of the swing arm and the winning door is interlocked by inserting the rear end of the winning door into a notch-shaped recess (C-shaped opening) formed on the front end side of the swing arm. Oscillating arm side opening type (see Patent Document 1), the front end of the oscillating arm is inserted into a notch-shaped recess (C-shaped opening) formed on the rear end side of the winning door, and the two are linked and connected. A winning door side opening type (see Patent Document 2) and the like are disclosed.

  Among these, the swing arm side opening type winning device has a relatively large swing angle (moving amount in the vertical direction), and the vertical height of the winning device is large. There are cases where it is disadvantageous to realize the reduction (thinning). On the other hand, in the winning door side opening type winning device, the swing angle of the swing arm can be easily suppressed as compared with the swing arm side opening type, which is advantageous for realizing a thin winning device. However, in the winning door side opening type, the front end of the swing arm enters the opening of the winning door and always slides, and thus power loss due to sliding resistance, twisting, wear, and the like are likely to occur. Therefore, if the swing angle of the swinging arm is further reduced in order to reduce the thickness of the winning device in this type, the sliding resistance of the swinging arm with respect to the winning door will increase, and the swinging arm or the winning prize will be increased. As a result, the durability of the winning device may be reduced.

  An object of the present invention is to provide a gaming machine winning device capable of reducing the thickness of the winning device without reducing durability by interlocking and connecting the transmission mechanism and the winning door with a simple and novel configuration. It is to provide a used gaming machine.

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 variable winning device for a gaming machine having a winning opening that opens in the left-right direction as a crossing direction and fixed to the gaming board,
The game board is parallel to the game board and is arranged so as to be rotatable about a rotation axis extending in the left-right direction, and the prize opening is closed by standing along the game board to introduce the game ball into the prize area. A winning door that displaces to a closed position that disables and an open position that allows the game ball to be introduced into the winning area by opening the winning opening by protruding in a crossing manner to the gaming area;
By holding a plunger that is linearly displaced in the front-rear direction at a front-side protruding position and a rear-side retracted position on one end side in the left-right direction of the winning opening, the winning door is moved around the rotation axis. A solenoid for rotating to displace between the closed position and the open position;
These winning doors are arranged between the winning door and the solenoid, and have a swing axis arranged in parallel to the pivot axis behind the pivot axis, and are connected to the plunger. Accordingly, the first action portion that swings around the swing axis and can maintain the winning door in the closed position by contacting the winning door at the rear side of the pivot axis, and the first action portion. The winning door can be shifted to the open position by contacting the winning door at the same height as or higher than the contact position between the action portion and the winning door and near the center in the left-right direction. A transmission mechanism including a second action part;
It is characterized by providing.

  A transmission mechanism (for example, a swing arm) of the award winning device for the gaming machine has a first action portion (for example, a main door that can maintain the winning door in a closed position by contacting the winning door behind the pivot axis of the winning door. The winning door is opened by contacting the winning door at the same height as or higher than the contact position between the first action part and the winning door and near the center in the left-right direction. And a second action part (for example, a protruding part) that can move to a position. In other words, the second action part for shifting the winning door to the open position is the center in the left-right direction at a height equal to or higher than the contact position between the first action part and the winning door for maintaining the winning door in the closed position. Since it abuts the winning door close to the section, the winning door can be opened and closed even if the swing angle of the transmission mechanism is small. In this way, by linking the transmission mechanism and the winning door with a simple and novel configuration using the first action part and the second action part formed in the transmission mechanism, the swing angle of the transmission mechanism can be reduced. Since it can be easily suppressed, it is possible to easily realize the thinning (downsizing) of the winning device.

  Moreover, even when the swinging angle of the transmission mechanism is further reduced in order to reduce the thickness of the winning device, the sliding resistance of the transmitting mechanism with respect to the winning door hardly increases, and the transmission mechanism, the winning door, and thus the winning device. Does not reduce durability. In addition, the first action part for maintaining the winning door in the closed position is located on the one end side in the left-right direction of the winning area by contacting the winning door closer to the center in the left-right direction than the first acting part. And is not located inside the winning opening, so that it does not hinder the flow of game balls introduced into the winning opening and moving in the winning area.

In addition, the winning device as described above is
(1) A winning door of a type (hereinafter also referred to as a self-supporting type) in which the center of gravity is located above or behind the rotation axis and tilts to the open position around the rotation axis when a moment based on external force is applied;
(2) A winning door of a type that tilts to an open position by its own weight (moving the center of gravity) when the center of gravity is positioned in front of the rotation axis;
It can be applied to any of the above.

Therefore, in the above winning device,
When the solenoid plunger is displaced from the retracted position to the projecting position and the transmission mechanism contacts the first contact portion and the first action portion of the winning door, the winning door can be maintained in the closed position,
When the plunger of the solenoid is displaced from the protruding position to the retracted position and the transmission mechanism comes into contact with the second contact portion and the second action portion of the winning door, the winning door can be shifted to the open position.

  Thus, when the first action part of the transmission mechanism and the first contact part (for example, the protrusion part) of the winning door come into contact, the winning door can be maintained in the closed position, and the second action part of the transmission mechanism and the winning door Since the winning door can be shifted to the open position when the second abutting portion (for example, the extending portion) comes into contact, the winning door can be smoothly displaced between the closed position and the open position.

  In this case, when the first action part and the second action part are formed in the transmission mechanism in a form having a predetermined phase angle in the swing direction around the swing axis, the winning door is closed. The first action part for maintaining the position and the second action part for shifting the winning door to the open position are arranged with a phase shift (offset: 齟齬) in the swinging direction, so that a predetermined value is established between the two action parts. Can be easily set.

As an example of a specific aspect of such a gaming machine winning device,
The transmission mechanism directly moves the driving force of the plunger to the winning door so that when the plunger is displaced to the protruding position, the winning door is displaced to the closed position, and when the plunger is displaced to the retracted position, the winning door is displaced to the open position. A transmission member capable of transmitting to
A first action part and a second action part can be formed on the transmission member.

  As described above, when the first action part and the second action part are formed on the transmission member that can directly transmit the driving force of the plunger to the winning door as the transmission mechanism, the transmission mechanism is configured to be compact. Therefore, it is possible to reduce the thickness of the winning device.

  At this time, the transmission member has a first swinging portion interlocked with the plunger (head portion thereof) and a second swinging portion engageable with the winning door, and the first action portion and the second action portion. The part may be formed in the second swing part. By forming the first action part and the second action part on the second swinging part of the transmission member, the transmission mechanism can be made more compact and the winning device can be made thinner.

More specifically,
The first action part is configured by a notch-shaped recess formed at the front end of the transmission member, and can be engaged with a protrusion formed as a first contact part projecting from the end face on the one end side in the left-right direction of the winning door. Placed in
The second action part is composed of a protruding part that protrudes from the laterally central end face of the transmission member, and an extension part that extends rearward from the rear end part of the winning door as the second abutting part; Arranged to be engageable,
When the winning door is displaced from the open position to the closed position, the notched recess of the transmission member presses and holds the projection of the winning door from above, while when the winning door is displaced from the closed position to the open position, the transmission member protrudes. The part can at least temporarily jump up the extension part of the winning door from below.

  Thus, the notch-shaped recess (first action part) of the transmission member presses and holds the projection part (first contact part) of the winning door from above, so that the winning door is displaced from the open position to the closed position, The projecting portion (second action portion) of the transmission member flips up the extension portion (second contact portion) of the winning door at least temporarily from below, whereby the winning door is displaced from the closed position to the open position. Therefore, when the winning door is displaced from the open position to the closed position and when the winning door is displaced from the closed position to the open position, the winning door and the transmission member abut (contact) at different portions (parts). The winning door can be smoothly displaced between the closed position and the open position.

As another example of a specific aspect of such a gaming machine winning device,
The transmission mechanism directly moves the driving force of the plunger to the winning door so that when the plunger is displaced to the protruding position, the winning door is displaced to the closed position, and when the plunger is displaced to the retracted position, the winning door is displaced to the open position. And a supporting member that can assist the opening operation of the winning door by the transmitting member mainly in the process of moving the plunger from the protruding position to the retracted position by swinging around the swing axis. And
While forming a 1st action part in a transmission member, a 2nd action part can be formed in an auxiliary member.

  As described above, when the transmission mechanism includes the transmission member that can directly transmit the driving force of the plunger to the winning door and the auxiliary member that can mainly assist the opening operation of the winning door by the transmission member. Can share the functions of the first action part to the transmission member and the second action part to the auxiliary member. And since the winning door can be smoothly displaced from the closed position to the opened position with a small force by the assistance of the auxiliary member, it can be easily applied to a self-weight type winning door.

  At this time, the transmission member has a first swinging portion interlocked with the plunger (head portion thereof) and a second swinging portion engageable with the winning door, and the first action portion is moved to the second swinging portion. You may form in a moving part. In addition, the auxiliary member has a first auxiliary swinging portion interlocked with the transmission member (first swinging portion thereof) and a second auxiliary swinging portion engageable with the winning door, The part may be formed in the second auxiliary swinging part. In this way, the first acting part is assigned to the transmission member, the second acting part is assigned to the auxiliary member, and the function is assigned to each other, and with the assistance of the auxiliary member, the winning door can be smoothly moved from the closed position to the open position with a small force. Can be displaced.

More specifically,
The first action part is configured by a notch-shaped recess formed at the front end of the transmission member, and can be engaged with a protrusion formed as a first contact part projecting from the end face on the one end side in the left-right direction of the winning door. Placed in
The second action part is composed of an auxiliary extension part that extends forward from the front end part of the auxiliary member, and engages with a rear protrusion part that protrudes rearward from the winning door as the second contact part. Arranged as possible
When the winning door is displaced from the open position to the closed position, the notch-shaped recess of the transmission member presses and holds the protruding portion of the winning door from above, while when the winning door is displaced from the closed position to the open position, the auxiliary member assists. The extending part can at least temporarily flip up the rearward protruding part of the winning door from below.

  Thus, the notch-shaped recess (first action part) of the transmission member presses and holds the projection part (first contact part) of the winning door from above, so that the winning door is displaced from the open position to the closed position, The auxiliary extension part (second action part) of the auxiliary member causes the rearward protruding part (second contact part) of the winning door to jump at least temporarily from below, whereby the winning door is displaced from the closed position to the open position. . Therefore, when the winning door is displaced from the open position to the closed position and when the winning door is displaced from the closed position to the open position, the winning door, the transmission member, and the auxiliary member abut (contact) at different portions (parts). Therefore, the winning door can be smoothly displaced between the closed position and the open position.

  Here, in a specific aspect of the above-mentioned game machine winning device, when the winning door is in the closed position regardless of whether the winning door is a self-supporting type or a dead weight type, the second action portion of the transmission member and the second winning door of the winning door By providing a gap that brings the contact portion into a non-contact state, play (instantaneous transmission stop) may occur when the winning door is displaced from the closed position to the open position. Such a temporary non-contact state (play) is included in “transmission of driving force by a transmission member (transmission mechanism)”.

Therefore, “the second action part of the transmission member (or auxiliary member) at least temporarily jumps up the second contact part of the winning door from below” includes the following two meanings.
(1) Regardless of whether the winning door is of its own weight type or self-supporting type, the winning door contacts (contacts) in a part of the section from the closed position to the open position; when the winning door is in the closed position, A gap is formed between the second action portion and the second contact portion of the winning door in a non-contact state. Thereby, the driving force of the solenoid (plunger) can be reduced.
(2) When the winning door is of its own weight type, the second operating portion of the transmission mechanism and the second contact portion of the winning door are brought into contact with each other over time from the initial non-contact state; The second action part of the transmission mechanism and the second contact part of the winning door are in a non-contact state in the entire section from the position to the open position. It will be in a contact state (contact). A contact state occurs when the pivot axis of the winning door is deformed by twisting due to changes over time, or when dust adheres to the pivot axis and it is impossible to tilt to the open position due to its own weight (movement of the center of gravity). . In the non-contact state, the driving force of the solenoid (plunger) can be reduced, and in the contact state, the winning door can be smoothly displaced from the closed position to the open position.

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 a result, by simply interlocking and connecting the transmission mechanism and the winning door with a simple and new configuration, the winning device can be thinned without reducing durability, and a gaming machine having an interesting board surface configuration can be achieved. It can be easily realized.

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 gaming machine winning device (hereinafter also simply referred to as a winning device) according to the present invention, and FIG. 2 is an overall perspective view illustrating an example of a winning device according to the present invention. 3 is an exploded perspective view, and FIG. 4 is a perspective view and a plan 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) 8 having a start winning opening and formed by a pair of rotating blade pieces 8a, 8a is disposed between the liquid crystal display unit 3 and the winning device 4. ing.

  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 FIGS. 1 and 2, 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). Accordingly, 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 enters the rear prize area 5b (FIG. 4 ( b) see).

  As shown in FIG. 3, the winning device 4 is arranged such that the winning door 10 (large winning door) attached to the base plate 5 corresponding to the winning opening 5a and the plunger 21 are linearly displaced in the front-rear direction. And a transmission mechanism 30 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 30 are accommodated in the lower case 4a and the upper case 4b and assembled to the base plate 5 (see FIG. 2). The lower case 4a and the upper case 4b have proximity switches 4c and 4c (winning ball detectors) for detecting a winning ball to the winning device 4, a sensor board 4d for transmitting winning ball detection data, A light emitting substrate 4e for illuminating the inside of the winning device 4 is also accommodated.

  As shown in FIG. 4, 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 5a, for example, parallel to the game board 2 (see 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 (see FIG. 1), the winning opening 5a is closed to make it impossible to introduce the game ball into the winning area 5b (see FIG. 5), and to the gaming area 2c. By projecting in an intersecting manner, the winning opening 5a is opened, and it is rotationally displaced to an open position (see FIG. 6) 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 along the rotation axis O1 at the lower ends of both side portions, and the rotating shafts 11 and 11 serve as the base plate 5 (or the lower case). 4a) is rotatably supported. In addition, it is good also as a form which forms a shaft hole instead of the rotating shafts 11 and 11, and is pivotally supported from 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 12a (first abutting portion) is formed so as to protrude in parallel with the rotation axis O1 from the left end face toward the outside. Further, an extension portion 12b (second contact portion) extending rearward is integrally formed at the rear end portion of the left side wall portion 12. As will be described later, these projecting portions 12 a and extending portions 12 b constitute an operated portion that receives an action from the transmission mechanism 30. The winning door 10 uses a self-weight type in which the center of gravity is positioned in front of the rotation axis O1 and tilts to the open position by its own weight (movement of the center of gravity).

  The solenoid 20 is arranged in the front-rear direction at the left end portion of the winning door 10 (winning port 5a), a plunger 21 having a head portion 22 formed at the front end portion protruding from the main body case 29, and a main body case 29 and a connection described later. A compression coil spring 23 (a resilient member) interposed between the frame 31 and the frame 31; The solenoid 20 holds the head portion 22 in the forward protruding position and the backward retracted position, thereby rotating the winning door 10 about the rotation axis O1 to displace it between the closed position and the open position. . 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. The head portion 22 is fixedly held by a holding portion 31c formed on a connecting frame 31 described later (see FIG. 5B).

  Next, the transmission mechanism 30 is arrange | positioned in the front-back direction along the moving direction of the plunger 21 in the left end part of the winning door 10 (winning opening 5a). The transmission mechanism 30 includes a swing arm 40 (transmission member) that swings around a swing axis O2 disposed in parallel to the pivot axis O1 behind the pivot axis O1 of the winning door 10, and a swinging arm 40. It has the connection frame 31 (connection member) which connects the moving arm 40 and the head part 22 of the plunger 21. 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 directly transmitted to the winning door 10 so that the winning door 10 is displaced to the open position (see FIG. 6).

  The swing arm 40 is formed in an L shape and is interlocked and connected to the head portion 22 of the plunger 21 so as to swing around the cylindrical swing shaft 41b (the swing axis O2) as the plunger 21 moves back and forth. A first arm 41 (first swinging part) and a second arm 42 (second swinging part) that can contact (engage) the winning door 10 behind the rotation axis O1 are included. The second arm 42 has a notch-like recess that can maintain the winning door 10 in the closed position by contacting the projection 12a (first contact portion) of the side wall portion 12 on the rear side of the rotation axis O1. 42a (first action portion), a higher position than the contact position between the notch-shaped recess 42a and the protrusion 12a, and the inner portion (side the center in the left-right direction) 12b (first portion) of the side wall portion 12 A projecting portion 42b (second action portion) is formed which is capable of shifting the winning door 10 to the open position by contacting the second contact portion.

  The notched recess 42a and the protrusion 42b are formed on the second arm 42 in a form having a phase angle θ in the swing direction (circumferential direction) around the cylindrical swing shaft 41b (swing axis O2). (See FIGS. 5 and 6). By arranging the notch-like recess 42a for maintaining the winning door 10 in the closed position and the projecting portion 42b for shifting the winning door 10 to the open position, the two are shifted in the circumferential direction (offset; 齟齬). The positional relationship between the action portions 42a and 42b can be easily set.

  The connection frame 31 slides and guides the cylindrical rocking shaft 41b of the first arm 41 by the long hole-shaped recess 31b (see FIGS. 5B and 6B), and the connection pin 31a is the first arm. The head portion 22 of the plunger 21 is fixedly held by the holding portion 31c.

  Specifically, when the plunger 21 of the solenoid 20 is displaced from the retracted position to the projecting position, the elongated hole-shaped recess 31b of the connecting frame 31 slides and guides the cylindrical swing shaft 41b in one direction ( The winning door 10 is maintained in the closed position by rotating in a clockwise direction in FIG. 6 (a), and the notched recess 42a of the second arm 42 presses and holds the projection 12a of the side wall 12 from above (FIG. 6). 5). On the other hand, when the plunger 21 of the solenoid 20 is displaced from the protruding position to the retracted position, the elongated hole-shaped recess 31b of the connecting frame 31 slides and guides the cylindrical swinging shaft 41b to move the first arm 41 in the reverse direction (FIG. 5 ( a), the projecting portion 42b of the second arm 42 jumps up the extending portion 12b of the side wall portion 12 from below, thereby moving the winning door 10 to the open position (see FIG. 6). . Thus, when the winning door 10 is displaced from the open position to the closed position (FIG. 6 → FIG. 5) and when the winning door 10 is displaced from the closed position to the open position (FIG. 5 → FIG. 6) Since the door 10 and the transmission member 30 (the second arm 42 of the swing arm 40) abut (contact) at different portions (parts), the winning door 10 can be smoothly displaced between the closed position and the open position.

  As shown in FIG. 5B, when the notch-like recess 42a of the second arm 42 and the projection 12a of the side wall portion 12 are in contact with each other (that is, when the winning door 10 is in the closed position), the second arm The protruding portion 42b of 42 and the extending portion 12b of the side wall portion 12 are in a non-contact state, and a gap S1 is formed between them. By providing the clearance S1, the driving force of the solenoid 20 (plunger 21) can be reduced, and the first arm 41 and the second arm 42 can be prevented from being twisted.

  As shown in FIG. 6A, when the winning door 10 is in the open position, the notch-shaped recess 42a of the second arm 42 and the protrusion 12a of the side wall 12 are separated from each other, and a gap S2 is formed therebetween. Has been. As described above, by providing the gaps S1 and S2, play (instantaneous transmission stop) occurs when the winning door 10 moves between the closed position and the open position. The engaged state (play) is handled as being included in “transmission of driving force by the transmission mechanism 30 (the swing arm 40)”.

  As described above, in this embodiment, the projecting portion 42b of the second arm 42 and the extending portion 12b of the side wall portion 12 are arranged in a part of the winning door 10 from the closed position (FIG. 5) to the open position (FIG. 6). However, the projecting portion 42b and the extending portion 12b may be brought into contact with each other over time from the initial non-contact state. That is, at the start of use, the projecting portion 42b and the extending portion 12b are not in contact with each other in the entire section from the closed position (FIG. 5) to the open position (FIG. 6). The both 42b and 12b are in a contact state (contact) in the entire section or a partial section. In other words, when the turning shaft 11 of the winning door 10 is deformed due to twisting or dust adheres to the turning shaft 11 due to a change over time, and it becomes impossible to tilt to the open position by its own weight (movement of the center of gravity). In addition, a contact state occurs. In this case, the driving force of the solenoid 20 (plunger 21) can be reduced in the non-contact state, and the winning door 10 can be smoothly displaced from the closed position to the open position in the contact state.

  Next, the operation of the winning device 4 having the above configuration will be described with reference to FIG. 1, FIG. 5 and FIG. 6 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 notch-shaped recess 42a of the second arm 42 closes the protruding portion 12a of the side wall portion 12 from above to close the winning door 10. Keep in position. Accordingly, the game balls flowing down the game area 2c are not introduced into the winning area 5b.

<Big hit state = open position> (FIG. 6)
When a game ball flowing down the game area 2c wins the electric chew 8, a winning lottery is executed, and if the lottery result is a big hit, a big hit symbol (for example, “7, 7, 7”) is displayed on the liquid crystal display unit 3. ) Is displayed. In the big hit state, the 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 projecting position to the retracted position, the projecting part 42b of the second arm 42 jumps up the extending part 12b of the side wall part 12 from below, so that the winning door 10 is opened. Migrate to As a result, game balls flowing down the game area 2c are introduced into the winning area 5b.

  When the proximity switches 4c and 4c detect a predetermined number (for example, 10) of winnings in the winning opening 5a, or when a predetermined time (for example, 30 seconds) elapses, the solenoid 20 is demagnetized again, and the plunger The head portion 22 of 21 is displaced from the retracted position to the protruding position, and the winning door 10 is displaced from the open 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.

  Thus, the protrusion 42b for moving the winning door 10 to the open position is at or above the height of the contact position between the notched concave portion 42a and the protrusion 12a for maintaining the winning door 10 in the closed position. Since it abuts the winning door 10 on the inner side, the winning door 10 can be opened and closed even if the swinging angle of the transmission mechanism 30 (swinging arm 40) is small. Therefore, the transmission mechanism 30 and the winning door 10 are interlocked and coupled with a simple and novel configuration using the notch-shaped recess 42a and the protrusion 42b formed in the second arm 42, thereby swinging the transmission mechanism 30. Since the corners can be easily suppressed, the winning device 4 can be easily made compact and thin (downsized).

  Moreover, even when the swing angle of the transmission mechanism 30 is further reduced in order to reduce the thickness of the winning device 4, the sliding resistance of the transmission mechanism 30 (swing arm 40) with respect to the winning door 10 hardly increases. In addition, the durability of the transmission mechanism 30 and the winning door 10 and thus the winning device 4 is not lowered. Further, the projecting portion 42b is in contact with the side wall portion 12 (extending portion 12b) inside the notch-shaped recess 42a, so that the notch-shaped recess 42a for maintaining the winning door 10 in the closed position is outside the winning area 5b. Since it is not located inside the winning opening 5a, it does not hinder the flow of game balls introduced into the winning opening 5a and moving in the winning area 5b.

(Example 2)
7 is a perspective view and a plan view of the main part showing another example of the winning device, FIG. 8 is a left side view and a right side view when the winning door is in the closed position, and FIG. 9 is the winning door in the open position. It is a left side view and a right side view at that time. A winning device 104 (a gaming machine winning device) shown in FIG. 7 includes a winning door 110 (large winning door) attached to the base plate 5 (see FIG. 3) corresponding to the winning opening 5a, and a plunger 21 in the front-rear direction. The solenoid 20 is disposed so as to be linearly displaced, and the transmission mechanism 130 is disposed between the winning door 110 and the solenoid 20 and transmits the driving force of the plunger 21 to the winning door 110.

  The transmission mechanism 130 is disposed in the front-rear direction along the moving direction of the plunger 21 at the left end portion of the winning door 110. This transmission mechanism 130 is the same as the swing arm 140 (transmission member) that swings around the swing axis O2 arranged in parallel to the pivot axis O1 behind the pivot axis O1 of the winning door 110. An auxiliary arm 150 (auxiliary member) that swings around the swing axis O2 is provided, and the connecting frame 31 of the first embodiment is omitted. The swing arm 140 displaces the winning door 110 to the closed position when the head portion 22 of the plunger 21 of the solenoid 20 is displaced to the protruding position (see FIG. 8), and when the head portion 22 of the plunger 21 is displaced to the retracted position. The driving force of the plunger 21 is directly transmitted to the winning door 110 so that the winning door 110 is displaced to the open position (see FIG. 9). The auxiliary arm 150 mainly assists the opening operation of the winning door 110 by the swing arm 140 in the process in which the head portion 22 of the plunger 21 moves from the protruding position (see FIG. 8) to the retracted position (see FIG. 9). Help).

  The swing arm 140 is connected to the head portion 22 of the plunger 21 in conjunction with the first arm 141 (the first arm 141) that swings around the cylindrical swing shaft 41b (the swing axis O2) as the plunger 21 moves back and forth. One swinging portion) and a second arm 142 (second swinging portion) that can contact (engage) the winning door 110 behind the rotation axis O1 are formed in parallel. The second arm 142 has a notch-like recess that can maintain the winning door 110 in the closed position by abutting against the protrusion 12a (first abutting portion) of the side wall portion 12 behind the rotation axis O1. 42a (first action part) is formed.

  The auxiliary arm 150 is linked to the first arm 141 and swings around the cylindrical swing shaft 151b (swing axis O2) as the plunger 21 moves back and forth. A swinging portion) and a second auxiliary arm 152 (second assisting swinging portion) that can contact (engage) the winning door 110 behind the rotation axis O1 are formed in series. The first auxiliary arm 151 is formed with an engagement long hole 151a (auxiliary arm side engaging portion) for penetrating and holding the engaging pin 141a (swinging arm side engaging portion) of the first arm 141. . Further, the second auxiliary arm 152 has a rear protruding portion 112b (the rear protruding portion 112b of the winning door 110) that is higher than the contact position between the notched concave portion 42a and the protruding portion 12a and inside (closer to the center in the left-right direction). An auxiliary extension portion 152b (second action portion) is formed that can shift the winning door 110 to the open position by abutting on the second abutment portion.

  Specifically, when the plunger 21 of the solenoid 20 is displaced from the retracted position to the projecting position, the notch-like recess 42a of the second arm 142 closes the protruding portion 12a of the side wall portion 12 to close the winning door 110. The position is maintained (see FIG. 8). On the other hand, when the plunger 21 of the solenoid 20 is displaced from the protruding position to the retracted position, a second time lag occurs while the engaging pin 141a of the first arm 141 moves through the engaging long hole 151a of the first auxiliary arm 151. The auxiliary extension portion 152b of the auxiliary arm 152 jumps up the rearward projecting portion 112b of the winning door 110 from below, thereby shifting the winning door 110 to the open position (see FIG. 9). Thus, when the winning door 110 is displaced from the open position to the closed position (FIG. 9 → FIG. 8) and when the winning door 110 is displaced from the closed position to the open position (FIG. 8 → FIG. 9), the winning is achieved. Since the door 110 and the transmission member 130 (the second arm 142 and the second auxiliary arm 152) abut (contact) at different portions (parts), the winning door 110 can be smoothly displaced between the closed position and the open position. .

  As shown in FIG. 8B, when the notch-shaped recess 42a of the second arm 142 and the protrusion 12a of the side wall 12 are in contact with each other (that is, when the winning door 110 is in the closed position), the second auxiliary The auxiliary extension part 152b of the arm 152 and the rear protrusion part 112b of the winning door 110 are in a non-contact state, and a gap S1 is formed between them. By providing the clearance S1, the driving force of the solenoid 20 (plunger 21) can be reduced, and the first arm 141 and the second arm 142 can be prevented from being twisted.

  Further, as shown in FIG. 9A, when the winning door 110 is in the open position, the notch-shaped recess 42a of the second arm 142 and the protrusion 12a of the side wall portion 12 are separated from each other, and a gap S2 is formed therebetween. Has been. As described above, by providing the gaps S1 and S2, play (instantaneous transmission stop) occurs when the winning door 110 moves between the closed position and the open position. The engaged state (play) is handled as being included in “transmission of driving force by the transmission mechanism 130 (swinging arm 140)”.

  Next, the operation of the winning device 104 having the above configuration will be described with reference to FIG. 1, FIG. 8, and FIG. 9 in relation to the gaming state in the gaming area 2c.

<Normal state = closed position> (FIG. 8)
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 110 in the closed position. Specifically, when the plunger 21 of the solenoid 20 is displaced from the retracted position to the projecting position, the notch-like recess 42a of the second arm 142 closes the protruding portion 12a of the side wall portion 12 to close the winning door 110. Keep in position. Accordingly, the game balls flowing down the game area 2c are not introduced into the winning area 5b.

<Big hit state = open position> (FIG. 9)
When a game ball flowing down the game area 2c wins the electric chew 8, a winning lottery is executed, and if the lottery result is a big hit, a big hit symbol (for example, “7, 7, 7”) is displayed on the liquid crystal display unit 3. ) Is displayed. In the big hit state, the 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 110 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 second auxiliary arm is moved after the engagement pin 141a of the first arm 141 moves through the engagement long hole 151a of the first auxiliary arm 151. The auxiliary extension part 152b of 152 jumps up the rearward projecting part 112b of the winning door 110 from below, thereby moving the winning door 110 to the open position. As a result, the game balls flowing down the game area 2c are introduced into the winning area 5b as in the first embodiment.

  In this embodiment, the notch-shaped recess 42a can be assigned to the swing arm 140 (second arm 142), and the auxiliary extension 152b can be assigned to the auxiliary arm 150 (second auxiliary arm 152). And, with the assistance of the auxiliary arm 150 (second auxiliary arm 152), the winning door 110 can be smoothly displaced from the closed position to the opened position with a small force.
