Description

  The present invention relates to a grand prize opening device provided in a ball game machine.

  In the case of a ball game machine, if a big win occurs based on the lottery result performed by entering a game ball into the starting port, the big winning port in the closed state is opened, and a large number of game balls are acquired. Many are made possible. A device related to a special electric accessory that controls the opening / closing of the special prize opening is a so-called attacker or the like.

  In recent years, in elastic gaming machines, increasing the screen size of the symbol display device and increasing the size of an accessory have become one trend with the aim of diversifying display screens and improving visual effects. Such an increase in the size of the liquid crystal display parts and accessories makes it necessary to secure a space for mounting various electronic parts in a limited space on the back side of the game board. It is desired to downsize the entire unit including the unit.

  To reduce the size of the unit, the first consideration is to reduce the size of the solenoid, which is the drive source of the open / close door attached to the winning prize opening, but this has its limitations. Therefore, conventionally, a solenoid is vertically placed, that is, a plunger driven by the solenoid is moved vertically and parallel to the board surface (Patent Document 1), or a solenoid is placed horizontally behind a space through which a game ball passes. In other words, there has been proposed (Patent Document 2) in which the moving direction of the plunger is horizontal and parallel to the board surface. However, in these arrangements, the thickness is still large, and when a ball distribution mechanism is provided in the big prize opening, there is a problem that the number of parts is further increased and an increase in thickness cannot be avoided.

  The present invention has been made in view of the above-described situation, and an object of the present invention is to provide a grand prize opening device that is significantly thinner than the conventional one.

The present invention relates to a base plate having an opening, a ball receiving member that rotates around a first axis in the opening, and a plunger that linearly moves in a direction parallel to the base in response to excitation and demagnetization of a solenoid. A second shaft that rotates by linear movement of the plunger, a link mechanism that associates the rotation of the first shaft and the rotation of the second shaft, a case fixed to the back surface of the base plate, and a substrate And the second shaft extends parallel to the base plate on the side opposite to the base plate with the plunger interposed therebetween, and the solenoid is on the opening side on the back side of the base plate. The case is disposed in a region outside the peripheral edge composed of a side and a lower side, and the case includes a sphere distribution unit provided with a sphere detection unit and a link mechanism storage unit, and a sphere detection unit and a link mechanism storage unit below the sphere distribution unit. The board is mounted between the solenoid and the plan Catcher, the link mechanism, ball outlet portion, sphere detection unit, and the substrate are both a winning opening device, each of thickness are arranged to overlap each other without Tsumikasanara.

  In the design concept of thinning in the conventional prize opening device, the focus is only on whether the solenoid is placed vertically or horizontally, both of which are arranged near the back of the opening of the prize winning opening. It is common. This is considered to be a fundamental cause that the thickness cannot be sufficiently reduced. In this configuration, the solenoid is disposed beside or below the opening on the back surface of the base plate, so that the thickness secured on the back surface of the base plate for the operation of the link mechanism that rotates the first shaft is dead. It can be used as a part of the thickness required for solenoid placement without using space, and it is occupied by the solenoid placement by placing the second shaft outside the plunger, that is, on the side far from the base plate. This thickness can be effectively utilized for a link mechanism that operates as the second shaft rotates.

  In the special prize opening device, the second axis is preferably parallel to the first axis. With this configuration, the link mechanism can be accommodated in a compact manner between the opening and the solenoid disposed in the region outside the periphery composed of the side and lower sides thereof, and the door opening and closing mechanism on the back side of the base plate It is possible to avoid becoming longer than necessary.

  In one aspect, the big prize opening device of the present invention is such that the solenoid is disposed on the side of the back upper opening of the base plate, and the plunger linearly moves parallel to the base plate in the vertical direction. With this configuration, the vertical placement of the solenoid on the side of the opening is realized.

  According to the present invention, the thickness secured on the back surface of the base plate for the operation of the link mechanism and the thickness occupied by the arrangement of the solenoid are not stacked to contribute to the thickness of the big prize opening device, but each Since the arrangement configuration overlaps, it is possible to achieve ultra-thinness, and it can be used as a space for mounting mechanical parts of other accessories and electronic parts that control them as much as they are thinned. it can.

  The big prize opening apparatus 1 of embodiment which concerns on this invention is demonstrated below, referring drawings. As shown in FIGS. 1 to 7, the grand prize opening device 1 includes a base plate 2 having an opening 3 and a door 6 that opens and closes the opening 3 by rotating around a first shaft 5. The case 4 is fixed by being addressed to the back surface of the plate 2, the plunger 8 linearly moves in a direction parallel to the base plate 2 in accordance with the excitation and demagnetization of the solenoid 7, and the linear motion of the plunger 8 rotates. A second shaft 9 and a link mechanism 11 that relates the rotation of the first shaft 5 and the rotation of the second shaft 9 are provided.

  On the front surface of the base plate 2, as shown in FIG. 2, an inclined base 14 that extends obliquely upward to the right from the vicinity of the apex formed by the upper side and the right side of the opening 3 is formed so as to protrude. On the back surface, as shown in FIG. 1, a ball feeding portion 15 is formed at the lower right of the opening 3 so as to protrude downward in a U shape. An example of the thickness of the base plate 2 (excluding the decorative portion) is 1 mm.

  As shown in FIGS. 1 to 5, the case 4 is provided with a door 6 having a size that covers the opening 3 of the base plate 2 when it is addressed to the base plate 2. A pair of shafts 12 are partially inserted and fixed to the lower left end and the lower right end of the door 6, respectively, and the remaining portions of the shaft 12 extending in the left and right directions are rotatable to corresponding positions in the case 4. Has been inserted. At this time, a line extending along the lower side of the door 6 through the center of the shaft 12 serves as a rotation shaft (first shaft 5) that can rotate with respect to the case 4. The maximum thickness of the case 4 can be exemplified as 18 mm.

  In the present specification, the first shaft 5 means an axis that is the center of rotation. Therefore, in this embodiment, the shaft 12 itself is the first shaft 5 that is not displaced relative to the case 4, but it is sufficient if a virtual rotation center line can be assumed, and a rod-like member such as the shaft 12 is sufficient. The first shaft 5 itself may be displaced relative to the case 4.

  The sphere circulation part 18 of the case 4 is set in a range in which one sphere can pass with an internal dimension in a vertical cross section orthogonal to the base plate 2, and as shown in FIG. A sphere detector 19 that covers and tilts in the lower right direction, defines a space having a bottom surface 16a, a rear wall 16b, a side wall 16c, a ceiling 16d, and an inclined plate 48, and has a circular through hole at the lower right end of the bottom surface 16a. The link mechanism storage unit 21 and the link mechanism storage unit 21 provided adjacent to each other with the inclined plate 48 (see FIGS. 3 and 8) on the left side of the ball distribution unit 18. On the left side, a partition 49 is provided adjacent to a solenoid housing 23 and a control board housing 25 that is formed on the right side of the ball detector 19 and houses the control board 24. Further, as shown in FIG. 1, an LED substrate 26 is attached to the case 4 with a screw 27 in a space sandwiched between the ball detection unit 19 and the link mechanism storage unit 21 below the ball distribution unit 18. .

  As shown in FIGS. 1, 3, 4, and 6, the solenoid 7 is disposed above the solenoid housing portion 23 in the case 4, and the plunger 8 is disposed below the solenoid housing portion 23 in the case 4. The plunger 8 is accommodated in such a direction as to move linearly in the vertical direction parallel to the base plate 2 by the excitation and demagnetization. The solenoid 7 is covered with a metal frame 31 in most of the four surfaces except the surface facing the base plate 2 and the opposite surface. The metal frame 31 reduces the influence of the magnetic field on the control board 24 and the LED board 26 that are arranged close to each other on the winning a prize opening device 1, and the electronic board arranged around the winning prize opening device 1, and accommodates a solenoid. The solenoid 7 is positioned above the portion 23.

  In addition, a part of upper surfaces of the solenoid accommodating part 23 and the metal frame 31 are notched, and the input terminal 32 of the solenoid 7 is exposed so that a voltage can be applied. Further, as shown in FIG. 6, a through-hole 33 about the diameter of the plunger 8 is opened in the lower surface of the metal frame 31, and the length of the plunger 8 with the tip portion facing the lower side of the solenoid housing portion 23. Almost half of this is in. The plunger 8 has two flanges 34 extending in the radial direction with a predetermined interval in the axial direction at the tip. An inverted coil spring 36 is interposed between the lower surface of the metal frame 31 and the flange 34 of the plunger 8, and urges the flange 34 toward the bottom surface 35 of the solenoid housing portion 23.

  The partition wall 49 between the lower part of the solenoid housing part 23 and the link mechanism housing part 21 is provided with a communication hole 37 that communicates with each other, and faces the surface of the solenoid housing part 23 where the communication hole 37 is opened. A shaft support hole 39 is also formed on the surface. The line connecting the center of the communication hole 37 and the center of the shaft support hole 39 is on the side opposite to the base plate 2 across the plunger 8, that is, on the side farther from the base plate 2 than the plunger 8. 1 extends in a direction parallel to the axis 5 and perpendicular to the direction of movement of the plunger 8.

  As shown in FIGS. 1 and 8, the rotating piece 38 is fitted at one end into a shaft support hole 39 provided in the partition wall 50, passes through the communication hole 37, and extends into the link mechanism housing portion 21. The hole 37 and the shaft support hole 39 are pivotally supported by the inner walls. The rotating piece 38 has a flat wing 41 extending toward the tip of the plunger 8 in the solenoid housing portion 23, and the end of the flat wing 41 is two flanges formed at the tip of the plunger 8. 34. A concave groove 41 a is formed on the side of the flat wing portion 41 far from the base plate 2, and is loosely fitted and guided by a convex portion protruding from the inner wall of the case 4. As described above, by inserting the rotation piece 38, the line connecting the center of the communication hole 37 and the center of the shaft support hole 39 is the rotation axis 9 (second axis) that can be rotated by the linear motion of the plunger 8. 9).

  In the present specification, the second shaft 9 means an axis serving as a rotation center that can be rotated by the linear motion of the plunger 8. Therefore, as long as a virtual rotation center axis can be assumed, it is sufficient as long as the rotation center axis satisfies the condition of extending parallel to the base plate 2 on the side opposite to the base plate 2 with the plunger 8 interposed therebetween. It may be displaced relative to the solenoid 7 itself. That is, in the present embodiment, the second shaft 9 is a rotation shaft that is not displaced relative to the solenoid 7, but may be a rotation shaft that is displaced relative to the solenoid 7.

  A door opening / closing hand 43 is formed at the other end of the rotating piece 38 as shown in FIGS. The door opening / closing hand 43 is a flat plate extending substantially along a plane perpendicular to the rotation shaft 9 and has a U-shaped pinching finger 45 at the tip. When the plunger 8 is in contact with the bottom surface of the solenoid housing portion 23, the pinch finger 45 points in the direction of the base plate 2 with the case 4 being placed on the base plate 2. The engaging joint 47 protrudes from the side of the door 6 into the link mechanism storage unit 21. The groove of the pinch finger 45 holds the pin 47a of the engagement joint 47 so as to be slidable and rotatable. That is, the door opening / closing hand 43 and the engaging joint 47 constitute the link mechanism 11.

  Here, as shown in FIG. 9A, in a state where the door 6 is closed, the surface D including the rotation shaft 9 and the flat wing portion 41 and the surface E including the rotation shaft 9 and passing between the pinching fingers 45. The angle between the engagement joint 47 is inevitably determined by the position height of the engagement joint 47, and is arbitrary as long as the state in which the finger 45 is sandwiched between the engagement joint 47 and the finger 45 can be maintained. As shown in FIG. 9 (b), a surface F including the pivot shaft 9 and passing between the pinching fingers 45 in the fully opened state of the door 6 in which the plunger 8 is most taken into the solenoid 7 is a base plate 2. It is desirable to set so that it is not parallel to This is because there is a possibility that the engaging joint 47 may come off the pinching finger 45 when it is parallel to the base plate 2. The surface G including the rotation shaft 9 and the flat wing portion 41 and the surface F including the rotation shaft 9 and passing between the pinching fingers 45 are generally parallel.

The function and operation based on the above configuration will be described below.
When a command for opening the big prize device 1 is output from an unillustrated elastic gaming machine main body, a voltage is applied to the input terminal 32 of the big prize opening device 1 and the solenoid 7 is excited. Then, the plunger 8 is drawn into the solenoid 7 against the elastic force of the coil spring 36. At this time, the flat blade portion 41 of the rotating piece 38 sandwiched between the flanges 34 at the tip of the plunger 8 is also lifted up, and the rotating piece 38 is centered on a line connecting the center of the communication hole 37 and the center of the shaft support hole 39. The whole rotates clockwise as indicated by an arrow R when viewed from the side of the shaft support hole 39 toward the connection hole 37. Along with the rotation of the rotating piece 38, the door opening / closing hand 43 stored in the link mechanism storage portion 21 in the angle posture as shown in FIG. 9A also rotates clockwise, and the fingertip of the pinch finger 45 is It faces diagonally upward as shown in 9 (b). In this process, the engaging joint 47 is lifted up and rotated counterclockwise as indicated by an arrow S to slide toward the base of the pinch finger 45. The above-described force applied to the engagement joint 47 acts to open the door 6 from the opening 3 of the base plate 2 toward the front surface with the first shaft 5 as a support shaft.

  A part of a sphere that jumps directly into the opening 3 with the door 6 open or a sphere that is dropped onto the upper surface of the inclined base 14 formed on the surface of the base plate 2 and guided to the opening 3 is a part of the inclined plate. 48, collides with the ball circulating portion 18 and rolls along the inclined bottom surface 16a, falls to the ball feeding portion 15 through the ball detecting portion 19, and is discharged therefrom. When a certain period of time elapses, voltage application to the solenoid 7 is stopped, and the plunger 8 comes out of the solenoid 7 by the elastic force of the coil spring 36 and returns to the state where it is pressed against the bottom surface 35. As a result, a force in the direction opposite to that described above acts on each member described above, and the door 6 is closed.

  In the present embodiment, the solenoid 7 is arranged on the side of the opening 3 on the back surface of the base plate 2, so that it is secured on the back surface of the base plate 2 for the operation of the link mechanism 11 that rotates the rotating shaft 5. The thickness of the rotating shaft 9 can be used as a part of the thickness required for the arrangement of the solenoid 7 without making it a dead space, and the rotating shaft 9 is arranged outside the plunger 8, that is, on the side far from the base plate 2. Thus, the thickness occupied by the arrangement of the solenoid 7 can be effectively utilized for the link mechanism 11 that operates as the rotation shaft 9 rotates.

  Since the rotation shaft 9 is parallel to the rotation shaft 5, the link mechanism 11 is compactly accommodated between the opening 3 and the solenoid 7 disposed in a region outside the peripheral edge including the side and the lower side. It is possible to prevent the opening / closing mechanism of the door 6 on the back side of the base plate 2 from becoming longer than necessary.

  Since the solenoid 7 is disposed on the back surface of the base plate 2 to the side of the opening 3 and the plunger 8 linearly moves in parallel to the base plate 2 in the vertical direction, the solenoid at the side of the opening 3 is provided. 7 vertical placement is realized.

  Since the thickness secured on the back surface of the base plate 2 for the operation of the link mechanism 11 and the thickness occupied by the arrangement of the solenoid 7 are overlapped with each other, an ultra-thin shape is achieved. It can be used as a space for mounting mechanical parts of other accessories and electronic parts for controlling them as much as it is thinned.

  Note that the present invention is not limited to the above-described embodiment, and modifications and the like can be made without departing from the technical idea of the present invention. Included in the technical scope.

  For example, the position and orientation of the solenoid 7 are arbitrary as long as the solenoid 7 is arranged in a region outside the peripheral edge composed of the side and lower sides of the opening on the back side of the base plate. The solenoid 7 may be housed in the lower part of the solenoid housing part 23 in the case 4 and the plunger 8 may be housed in the upper part of the solenoid housing part 23 in the case 4 while maintaining the direction of the linear motion. Further, the solenoid 7 may be placed horizontally below the opening 3, that is, so that the moving direction of the plunger 8 is parallel to the base plate 2 and in the horizontal direction. At this time, if the first shaft 5 is provided along the lower side of the door 6 as in the above embodiment, the first shaft 5 and the second shaft 9 are orthogonal to each other. As a link mechanism 11 that relates the rotation of the second shaft 9 to the rotation of the first shaft 5 when the first shaft 5 and the second shaft 9 are orthogonal to each other, for example, Japanese Patent Laid-Open No. 2013-2003 Various conventionally known mechanisms such as the configuration described in 230276 and bevel gears can be employed. Moreover, as a ball | bowl receiving member, you may employ | adopt the opening / closing member of Unexamined-Japanese-Patent No. 2013-223590 besides the door 6 in the said embodiment.
