Description

  The present invention relates to a winning device in which a winning of a game ball into a winning opening is allowed / blocked by opening / closing a door installed on a game board.

  A pachinko game machine, which is a typical game machine, is a graphic display device such as a liquid crystal type or a drum type that plays a symbol change game by changing and stopping various symbols in a game area of a game board set in the machine. Is arranged at a position below the game board, and a start winning tool is provided as an opportunity to start the symbol variation game on the symbol display device. In addition, a special winning device (winning device) that is opened only when a special game occurs and allows a winning of a game ball is arranged below the starting prize-winning device, and the game ball is awarded to the special winning device. By doing so, a prize ball is paid out to a ball tray provided on the machine surface side by a ball payout device arranged on the back side of the gaming machine.

  FIG. 8 is a schematic explanatory view showing the main part of a general prize-winning device 60 that has been conventionally used, and is provided with an open / close door 62 that can be opened and closed on the front surface of the game board, and a drive source for the open / close door 62. And a swing member 64 that connects the plunger of the solenoid to the open / close door 62. On the back surface of the open / close door 62, an engaging portion 70 formed in a substantially U shape by upper and lower protrusions 66, 68 is provided, and extends from the base 72 of the swing member 64 to the front side. The open end (abutting portion) 74 a of the piece 74 is engaged in a state where it faces the inside of the engaging portion 70. The base 72 of the swinging member 64 is connected to a solenoid plunger at the upper portion thereof, and the swinging member 64 swings about the swinging shaft when the plunger reciprocates. Yes. That is, in the non-excited state of the solenoid, as shown in FIG. 8A, the swinging member 64 is maintained in a posture in which the extending piece 74 is inclined downward, and the contact portion 74a is The free opening of the open / close door 62 is restricted by contacting the lower protrusion 68 of the open / close door 62 from above. On the other hand, in the excitation state of the solenoid, the swinging member 64 is swung to raise the extending piece 74, whereby the protrusion 66 on the upper side of the open / close door 62 is pushed up to the contact portion 74a. Thus, the open / close door 62 is opened.

  By the way, in the winning ball confirmation operation of the winning device 60 performed in the inspection process of the gaming machine, it is necessary to forcibly open the open / close door 62 to win the gaming ball in the non-excited state of the solenoid. In addition, when the game ball is compensated for due to a malfunction during the game, there is a situation where the door 62 is forcibly opened. Therefore, as shown in FIG. 8A, the conventional prize-winning device 60 is shown in FIG. 8B when the open / close door 62 is forcibly opened with fingers even when the open / close door 62 is in the closed state. As shown, the opening / closing door 62 can be opened relatively easily against the effectiveness of the plunger.

However, such an open / close door 62 that can be opened relatively easily is often used in reverse, and the open / close door 62 is illegally opened using a cell board, piano wire, etc. is doing. In other words, a small hole is opened with a tool brought in at the ball outlet of the ball tray of the gaming machine, and an illegal device bent in a bowl shape is allowed to enter the game area through the small hole, thereby forcibly opening and closing the door 62. It is a fraudulent act that is opened to the public, which causes serious damage to the game store. Therefore, Patent Document 1 proposes a winning device including a lock mechanism that restricts the opening of the door when the solenoid is not excited. According to the winning device disclosed in Patent Document 1, the locking mechanism always locks the door in a non-excited state of the solenoid, so that the illegal act can be suitably prevented.
JP 2000-279585 A

  In the winning device disclosed in Patent Document 1, since the lock mechanism always locks the open / close door when the solenoid is not excited, it is completely impossible to open the open / close door with fingers. Therefore, when performing a prize ball check or prize ball compensation, an operating rod is inserted into an insertion hole provided in the front of the winning device, and the plunger is pushed by the operating rod to open the door. Yes. However, the operation of inserting the operating rod through such an insertion hole is very complicated, and it is pointed out that the work efficiency is lowered. In particular, for the prize ball compensation, a quick work is required so as not to wait for the player.

  Accordingly, the present invention has been proposed to solve the above-mentioned problems inherent in the conventional winning device, and it is proposed to solve this problem. It is an object of the present invention to provide a winning device that can suppress a decrease in workability of the opening work at times.

In order to overcome the above-mentioned problems and achieve the intended purpose, the winning device according to claim 1 is:
An open / close door (27) pivotally supported by the device body (21) attached to the game board (10) so as to be openable and closable, allowing a game ball to be awarded when opened and restricting a game ball when closed; A drive means (32) disposed in the apparatus main body (21) and a swinging drive by the drive means (32) to contact the restricting portion (28) provided in the open / close door (27) (42 ) Abutment surface (N) abuts to restrict the opening of the door (27) and pushes up the protrusion (26) provided on the door (27) to open the door (27) A winning device including a swinging member (24) that can be displaced in a second posture that releases
Abutment surface of the front abutment KiYurado member (24) (42) (N), the rotational center of the pivot center (O ₁₎ and door of the swing member in the first position (24) A lower part of the reference line (L) connecting (O ₂ ), and abuts on the regulating part (28) of the open / close door (27),
The shape of the contact surface (N) at the contact point (P) with the restricting portion (28) is:
When the opening / closing door (27) is forcibly opened while the swinging member (24) is in the first posture , the contact (P) and the swing center (O ₁ ) Forced opening force as vertical drag on the opening direction side of the swinging member (24) from the first posture to the second posture with respect to the connecting line and on the swinging center (O ₁ ) side of the contact (P) with (F) acts on the abutment surface (N), the forced opening force (F) is formed at an angle (theta) in the range of 10 ° to 70 ° relative to the line segment,
When the forced open the door (27), the forced opening force (F) is, with the pivot center of the contact (P) (O ₁₎ resistive force acting toward the direction (F _1), The swing member (24) is configured to be disassembled into a rotational force (F ₂ ) acting in an opening direction from the first posture toward the second posture ,
The lower part of the contact surface (N) from the contact (P) is the swing center (O ₁ ) side of the swing locus (C ₁ ) of the swing member (24) at the contact (P). It is characterized by being configured to be located at.
According to the first aspect of the present invention, the force acting on the swinging member through the opening / closing door when the opening / closing door is opened is the rotational force of the swinging member in the opening direction and the swing center from the contact portion. Broken down into resistance in the direction. That is, the force that opens the door does not directly act as a rotational force in the opening direction of the swinging member, but a part of it is decomposed as a resistance force. The power can be increased. Therefore, it becomes difficult to open the door with a fraudulent instrument, and it is possible to suppress the occurrence of the goto action. Further, when performing a prize ball check or the like, the open / close door is opened with fingers, so that there is little deterioration in workability with only a slight resistance. In addition, since the forced opening force makes an angle in the range of 10 ° to 70 ° with respect to the line segment connecting the contact point and the swing center, the resistance force becomes large and the forced opening becomes difficult, or the rotational force Does not increase the likelihood of anti-fraud prevention.

In the winning device according to claim 2, the contact surface (N) of the swinging member (24) in the first posture is such that the resistance force (F ₁ ) is larger than the rotational force (F ₂ ). It was configured to disassemble the forced opening force.

  According to the winning device according to the present invention, it is possible to suppress fraud by making it difficult to open the open / close door, and the deterioration in workability such as winning ball confirmation and winning ball compensation in the inspection process is minimized. Can be suppressed.

  Next, the winning device according to the present invention will be described in detail below with reference to the accompanying drawings by way of preferred embodiments. In the embodiment, a general pachinko machine that plays a game using a game ball will be described as an example. In the following description, front / rear and left / right are designated when the game board of the pachinko machine is viewed from the front as shown in FIG. 1 unless otherwise specified.

  FIG. 1 shows a front view of a game board 10 provided in a pachinko machine. The game board 10 according to the embodiment is formed in a rectangular shape, and a rail 10a that is curved in a substantially circular shape is attached to the front side thereof. A game area 11 defined by the rail 10a is provided by a launcher (not shown). A game ball (not shown) is launched. In addition, a large decorative member 14 having a symbol display device 13 such as a liquid crystal type or a drum type capable of various symbol variations and stop display is disposed above the game board 10. The game ball that has been launched into the winning prize 16 is placed on the start winning tool 16 disposed below the decorative member 14 of the game board 10, thereby changing the symbol on the symbol display device 13 and starting the required symbol variation game. It is like that. Then, as a result of the symbol variation game, a special game (so-called big hit) advantageous to the player is generated by displaying a specific symbol combination (for example, a triple of the same symbols) on the symbol display device 13. It is configured as follows. In addition, a winning device 20 (described later) that is opened when the special game is generated and allowed to win a game ball is disposed below the gaming board 10, and the game ball wins the winning device 20. Thus, a prize ball is paid out to a ball tray (not shown) provided in the pachinko machine.

  As shown in FIGS. 2, 3, and 7, the winning device 20 is provided with a device main body 21 attached to the back (rear) side of the game board 10 and a front side of the device main body 21 with a required decoration. It is basically composed of a fixed decorative board 22 applied, and is screwed and fixed to the game board 10 through four through holes 22a, 22a, 22a, 22a formed near the corners of the fixed decorative board 22. The The fixed decorative plate 22 is provided with a horizontally-long rectangular winning opening 23 through which a game ball can pass, and is defined in the apparatus main body 21 and has a front opening portion of a winning space 25 having a required depth. Consistent. Further, as shown in FIG. 2, the apparatus main body 21 is provided with a ball discharge port 30 for discharging game balls won in the winning space 25 to the back side. The open / close door 27 for opening and closing the winning opening 23 is formed in a horizontally long rectangular plate substantially aligned with the winning opening 23, and shafts 27a and 27a (see FIG. 4) formed at the lower ends of the left and right side surfaces thereof. (Only one is shown) is pivotally supported with respect to the apparatus body 21 so as to be swingable in the front-rear direction. As shown in FIGS. 4 and 5, an open engagement piece that contributes to opening and closing of the opening / closing door 27 is brought into contact with and engaging with a swing member 24 described later on the left side of the back surface of the opening / closing door 27. A (projection) 26 and an opening restriction piece (regulation part) 28 are formed to project rearward.

  As shown in FIG. 3, a solenoid (driving means) 32 is assembled to the left rear portion of the apparatus main body 21, and a plunger 36 of the solenoid 32 always urged forward by the elastic member 34 is slidable in the front-rear direction. It is extended. A disc-shaped engagement plate 38 provided at the front end of the plunger 36 is connected to the swing member 24 positioned in front of the solenoid 32. As shown in FIG. 4, the swinging member 24 protrudes forward from the base portion 40 having first and second engaging portions 24 a and 24 b provided to be separated from each other in the front-rear direction and from the front portion of the base portion 40. An extension piece (abutment portion) 42 is provided on the base body 40 so as to be swingable in the up-down direction via a support shaft 40a extending in the left-right direction. That is, the plunger 36 is connected to the swing member 24 by the engagement plate 38 being positioned and engaged between the first engagement portion 24a and the second engagement portion 24b. As the member 36 slides back and forth, the swing member 24 is swung around the support shaft 40a.

  The front end of the extension piece 42 abuts on the opening restriction piece 28 when the opening / closing door 27 is closed, and abuts on the opening engagement piece 26 from below when the opening / closing door 27 is opened. Set to engage and push up. That is, as shown in FIG. 4A, when the solenoid 32 is in a non-excited state, the plunger 36 is extended forward by the elastic member 34, and the engagement plate 38 is the first member of the swing member 24. 1 The engaging part 24a is pressed. As a result, the swing member 24 is in the first posture in which the extending piece 42 is inclined downward to the front side, and the front end of the swinging member 24 abuts on the opening restricting piece 28 to maintain the open / close door 27 in the closed state. To do. Further, as shown in FIG. 4B, when the solenoid 32 is excited, the plunger 36 is drawn against the elastic force of the elastic member 34, and the engagement plate 38 is pulled into the second engagement portion 24b. The rocking member 24 is rocked by engaging. As a result, the swing member 24 assumes a second posture in which the extending piece 42 is inclined upward to the front side, and the extending engaging piece 26 is pushed up (bounced up) by the extending piece 42, and the opening / closing door 27 is moved. Open. In the following description, the swinging direction of the swinging member 24 from the first posture to the second posture is referred to as an open swinging direction.

Here, a contact structure between the extending piece 42 of the swinging member 24 and the opening restricting piece 28 of the opening / closing door 27 will be described in detail with reference to FIG. Assuming that a line segment connecting the swing center (center of the support shaft 40a) O _{1 of the} swing member 24 and the rotation center (center of the shaft portion 27a) O ₂ of the open / close door 27 is a reference line L, the first posture is set. The contact P between the extending piece 42 of the swing member 24 and the opening restricting piece 28 of the open / close door 27 is set to be positioned below the reference line L. In addition, an abutting surface N that is inclined so as to be separated from the open / close door 27 from the top to the bottom in the first posture of the swing member 24 is formed at the end of the extension piece 42. When a force in the opening direction (front side) is applied to the open / close door 27 with the swinging member 24 in the first posture (see arrow A in FIG. 5), the opening restriction piece 28 is It tries to rise around the part 27a. Then, it acts as a force (vertical drag) F in the vertical direction of the contact surface N from the opening restriction piece 28 to the extension piece 42 (swing member 24) that comes into contact with the opening restriction piece 28 at the contact P. . That is, the force F means a force (forced opening force) that acts on the swing member 24 through the opening / closing door 27 when the opening / closing door 27 is forcibly opened. Here, when a line segment connecting the rotational center O ₂ and the contact point P and rotational force line l _2, the real force door 27 tries to rotate in a direction perpendicular to the turning force line l ₂ (i.e. , Expressed as a force F ′ in the tangential direction at the contact point P of the rotation locus C ₂ of the opening / closing door 27. However, the rotational force F ′ is decomposed into the forced opening force F and the force f in the direction along the contact surface N, and this force f does not act as a force for swinging the swinging member 24. It is considered that the forced opening force F acts on the swing member 24.

Further, as shown in FIG. 5, the forced opening force F includes a component force (resistance force F ₁ ) from the contact P in the direction of the swing center O _1, and a swing locus C of the swing member 24 at the contact P. ₁ and the component force (rotational force F ₂ ) in the oscillating direction of the oscillating member 24 in the open oscillating direction. In other words, due to the inclined shape of the contact surface N of the extended piece 42, the forcible opening force F acting on the swing member 24 is a line segment (resistance action line) connecting the contact P and the swing center O _1. l ₁ ) extending to a region on the opening direction side (upper side in FIG. 5) and a region on the oscillating center O ₁ side (left side in FIG. 5) in the tangential direction at the contact point P of the oscillating locus C ₁ . It is supposed to be. Since the swing member 24 is supported by the support shaft 40a, the resistance force F ₁ acting from the contact point P toward the swing center O ₁ disappears (cancels), and only the rotational force F ₂ is present. This contributes to the rocking of the rocking member 24. That is, a force necessary for forcibly opening the open / close door 27 (a force required to push the plunger 36 against the elastic force of the elastic member 34) is required more than before. On the other hand, when a certain amount of force is applied to the open / close door 27, the open / close door 27 is forcibly opened.

The shape of the contact surface N of the extending piece 42 is set so that the angle θ of the forced opening force F made with respect to the resistance acting line l ₁ becomes a value in the range of 10 ° to 70 °. . That is, if the value of the angle θ is set to be small, the resistance force F ₁ is increased accordingly, and it is difficult to perform forced opening (see FIG. 6A). Therefore, if the angle θ is smaller than 10 °, the forced opening of the opening / closing door 27 becomes very difficult, which may hinder the winning ball check operation. On the contrary, when the angle θ is set to be large, the resistance force F ₁ is decreased and the rotational force F ₂ is increased, so that the forced opening is easily performed (see FIG. 6B). Therefore, when the angle θ is larger than 70 °, the forced opening is facilitated, and the effect of preventing illegal acts cannot be expected. Further, the shape of the portion of the opening restricting piece 28 that comes into contact with the extending piece 42 is not particularly limited. However, as shown in FIG. 5, it is slightly curved to prevent the protruding piece 42 from being caught. desirable. However, as in the embodiment, it is not always necessary to curve the entire open end face of the opening restricting piece 28. For example, a hemispherical protrusion may be provided on a portion of the opening restricting piece 28 that contacts the extending piece 42, Only the part to contact may be formed in a curved shape, and the other part may be formed in a flat shape.

  As shown in FIG. 7, an R-shaped portion 44 that curves backward is formed on the upper surface of the opening / closing door 27. Further, on the upper edge of the winning opening 23 established in the fixed decorative plate 22, a back plate member 46 with which the upper back surface of the open / close door 27 abuts at the time of closing extends across the entire width of the winning opening 23. In addition, a rib 48 protruding forward is formed on the upper portion of the back plate member 46. A space S is defined by the rib 48 and the back plate member 46, and the upper portion of the open / close door 27 at the time of closing is accommodated in the space S. That is, as shown in FIG. 7A, the vertical dimension M of the opening / closing door 27 is set larger than the vertical dimension m of the winning opening 23, and the opening / closing door 27 is accommodated inside the winning opening 23. Instead, the winning opening 23 is closed in a state where the upper portion is slightly inclined forward and overlapped with the back plate member 46.

  By adopting such a structure, the following effects are exhibited. In the conventional general opening / closing door, the entire opening / closing door is accommodated inside the winning opening when closed. Further, in recent years, there is an increasing tendency to increase the size of the symbol display device, and accordingly, the vertical dimension of the winning device 20 is required to be reduced. However, since the conventional winning device has a structure in which the opening / closing door is accommodated in the winning opening, in order to narrow the vertical dimension of the winning device, the vertical dimension of the opening / closing door must also be reduced. However, if the vertical dimension of the open / close door is reduced, the open / close door that is opened during the special game cannot be reliably received, and there is a limit to reducing the vertical dimension of the winning device. On the other hand, in the winning device 20 according to the embodiment, since the opening / closing door 27 is closed so as to cover the winning opening 23 as described above, the vertical dimension M of the opening / closing door 27 is determined. Only the vertical dimension m of the winning opening 23 can be reduced without reducing the size. Accordingly, it is possible to suitably realize reduction in the vertical dimension of the winning device 20 required as the symbol display device 13 becomes larger. 7B, the rib 48 is formed at a position where the upper end of the R-shaped portion 44 and the lower end of the rib 48 are slightly separated when the door 27 is closed. Thus, it is difficult for the unauthorized appliances or the like to enter from the gap between the upper end of the open / close door 27 and the winning opening 23.

(Effects of Example)
Next, the operation of the winning device 20 according to the embodiment will be described. The game balls launched into the game area 11 along the rails 10a provided on the game board 10 come into contact with game nails, windmills, etc. provided on the game board 10 and flow down while changing the flow direction. At this time, the solenoid 32 is in a non-excited state, and the plunger 36 is extended forward by the elastic force of the elastic member 34 as shown in FIG. Accordingly, the swinging member 24 assumes the first posture, the extension piece 42 contacts the opening restriction piece 28, and the open / close door 27 is maintained in the closed state. That is, when the solenoid 32 is in a non-excited state, the open / close door 27 is maintained in a closed posture, and winning of a game ball is restricted.

  When a game ball flowing down the game area 11 wins the starting prize device 16, a required symbol variation game is started on the symbol display device 13, and as a result of the symbol variation game, a specific symbol set is displayed on the symbol display device 13. When the match is displayed, a special game is generated. Then, the solenoid 32 is excited and the plunger 36 is pulled against the elastic force of the elastic member 34. As a result, as shown in FIG. 4B, the swinging member 24 is swung in the opening direction, and the extension piece 42 pushes up the opening engaging piece 26 to open the opening / closing door 27. Winning of game balls into the winning opening 23 is allowed. When the special game is completed under a predetermined condition, the energization to the solenoid 32 is stopped, and the plunger 36 is slid forward by the elastic member 34. Along with this, the swinging member 24 swings downward, the extending piece 42 comes into contact with and engages with the opening restricting piece 28, pushes down the opening restricting piece 28, and closes the open / close door 27.

Here, for example, it is assumed that a fraudulent act in which a linear fraudulent device bent in a bowl shape is made to enter the game area and the open / close door 27 in the closed state is forcibly opened is performed. That is, when an unauthorized instrument is hooked on the upper part of the opening / closing door 27 and the opening / closing door 27 is forced to open, the force acting on the swing member 24 via the opening / closing door 27 is as shown in FIG. It acts on the swing member 24 as a forced opening force F. However, since the contact surface N is inclined from the upper side to the lower side, the forced opening force F is decomposed into the resistance force F ₁ and the rotational force F ₂ . That is, the forced opening force F acting on the swing member 24 does not all act as a force in the opening direction of the swing member 24, but the resistance force F _{1 in the} resistance acting line l ₁ direction disappears. Only the rotational force F ₂ contributes. Therefore, the force required to forcibly open the opening / closing door 27 becomes large, and it may be difficult to open the opening / closing door 27 due to fraud.

  In addition, when performing a game machine manufacturing process or a prize ball check or a prize ball compensation performed at a game store, a slight force is applied so that the extension piece 42 and the opening restriction piece 28 are in contact with each other. The opening / closing door 27 can be forcibly opened. Here, the prize ball confirmation, the prize ball compensation, and the like are normally performed by opening the opening / closing door 27 with fingers. 27 can be opened relatively easily. That is, in the winning device 20 according to the embodiment, the force required to forcibly open the opening / closing door 27 is increased, and the forced opening of the opening / closing door 27 due to fraudulent acts can be suppressed. It is not something that requires enough power.

  As shown in FIGS. 7A and 7B, the upper portion of the door 27 is formed in a space S defined by the upper edge of the winning opening 23 of the fixed decorative plate 22 by the back plate member 46 and the rib 48. There is only a slight gap between the upper end of the R-shaped portion 44 and the lower end of the rib 48. In addition, since the upper part of the opening / closing door 27 is a curved R-shaped part 44, it becomes very difficult to insert and hook an unauthorized instrument on the upper part of the opening / closing door 27 when the door is closed. Can be prevented. In the embodiment, since the opening / closing door 27 is closed so as to cover the winning opening 23, only the vertical dimension m of the winning opening 23 is reduced without reducing the vertical dimension M of the opening / closing door 27. And the vertical dimension of the winning device 20 can be reduced.

As described above, according to the winning device 20 according to the embodiment, when the opening / closing door 27 is opened, the forced opening force F acting on the swinging member 24 via the opening / closing door 27 is generated by the swinging member. 24 is broken down into a rotational force in the open swing direction and a resistance force in the swing center direction from the contact portion. That is, the force for opening the door 27 is not directly applied as a rotational force in the opening swing direction of the swing member 24, but a part thereof is dispersed as the resistance force F _1. The force required to open 27 can be increased. Therefore, it becomes difficult to open the door 27 by an unauthorized tool, and it is possible to suppress the occurrence of goto action. In addition, when opening and closing door 27 with fingers in the prize ball confirmation or the like, the workability is not deteriorated only by feeling a slight resistance. Furthermore, by making the contact surface N of the swing member 24 into an inclined shape, the forced opening force F is preferably decomposed into a resistance force F ₁ and a rotational force F ₂ . Further, if the inclination angle of the contact surface N is changed, the degree of force required to open the opening / closing door 27 can be adjusted.

In the embodiment, the shape of the contact surface N of the swing member 24 is configured as an inclined surface. However, the shape is not limited to a flat surface as in the embodiment, and the forced opening force F is equal to the resistance force F ₁ and the rotational force. Any shape that can be decomposed into F ₂ is acceptable. That is, the direction of the forced opening force F is defined by the shape (inclination angle, curvature, etc.) of the contact P on the contact surface N, and the forced opening force F is determined by the resistance force F ₁ and the rotational force F _2. If it can be disassembled, the shape of the contact surface N may be a curved surface or a stepped shape.

When the swing member is forced open the door while in the first position, at the contact, the second posture from the first posture of the swing member than the line segment connecting the contact and the swinging center in the heading the opening direction side, and with forced opening force as normal force to the swing center side than said contact is applied to the contact surface, the forced opening force is 10 ° to 70 ° relative to the line segment Formed to make a range angle ,
When the forced open the door, the forced opening force is a resistance force acting toward from said contact to the swinging center direction, towards the first position of the swinging member in the opening direction towards the second position is configured to be decomposed into a torque acting Te,
A winning device characterized in that a portion of the contact surface below the contact point is positioned closer to the swing center side than the swing locus of the swing member at the contact point. The winning device according to claim 1 , wherein the contact surface of the swing member in the first posture is configured to decompose the forced opening force so that the resistance force is larger than the rotational force .
