  In FIG. 2, the electric-chu type winning device 10 has a mounting base plate 11 that is attached to the board surface of the game board 2 through the mounting hole 45, and a ball receiving opening 13 that receives a game ball in the upper center of the mounting base board 11. The U-shaped upper ball guide path portion 12 to be configured is attached so as to pass through the front and rear of the mounting base plate 11. The front face decoration board 14 is attached to the front surface of the upper ball guide path portion 12, and the winning game balls received by the ball receiving openings 13 so as to be connected to the rear end of the upper ball guide path 12 are faced sideways. An upper rear ball guide path member 15 to be guided is attached. A lower ball receiving portion 16 is integrally attached to the front surface of the lower center of the mounting base plate 11, and a lower ball guiding path portion 18 is attached to the rear surface of the lower central portion of the mounting base plate 11. A lower ball receiving portion front decorative plate 17 is attached to the front surface of the lower ball receiving portion 16, and a pair of opening / closing blades 19 serving as an opening / closing member is opened between the lower ball receiving portion front decorative plate 17 and the mounting base plate 11. It is provided to change between a state and a closed state. The opening / closing blade 19 is driven to open and close by a solenoid 20. The detailed structure will be described later in detail.

  In the present embodiment, the mounting base plate 11, the upper ball guide path portion 12, the receiving front decorative plate 14 and the opening / closing blade 19 are formed of a transparent synthetic resin (for example, polycarbonate) having translucency. As will be described in detail later, the light decoration effect can be exhibited by the light emitted from the LED. In addition, the surface of the receiving face front decorative plate 14 is color-printed by inkjet, but the device has been devised to increase the light transmittance by making the dot density coarser than the general density. Yes. Further, the game ball received by the opening / closing blade 19 is guided from the lower ball receiving portion 16 to the lower ball guiding path portion 18 and discharged from the electric-chu type winning device 10. For this reason, the lower ball receiving portion 16 and the lower ball guiding portion 18 are attached to the front and rear surfaces of the mounting base plate 11 so as to incline downward (may be integrally molded). An opening through which is passed is formed.

  Further, the electric chew type winning device 10 has a configuration other than the above, a first LED substrate 21 on which a plurality of LEDs 22 for light-decorating the peripheral portion of the mounting base plate 11 are mounted, and a U-shaped upper ball. The second LED board 25 on which the LED 26 for light-decorating the guide path portion 12 is mounted, and the third LED board 28 on which the LED 29 (see FIG. 5) for light-decorating the opening / closing blade 19 is mounted. 11 is provided at a position parallel to the mounting base plate 11 on the rear surface side. Hereinafter, the structure for optically decorating each member will be described.

  First, the structure for optically decorating the mounting base plate 11 will be described with reference to FIGS. A first LED substrate 21 is provided at a predetermined interval behind the mounting base plate 11. A plurality of LEDs 22 are circumferentially mounted on the front surface of the first LED substrate 21 at a predetermined interval. And the prism part opening groove | channel 23 as a prism part is located in the front position corresponding to these LED22. As shown in FIG. 3C, the prism portion opening groove 23 has a cross section having an inclined surface that reflects the optical path a of the light emitted from the LED 22 of the LED substrate 21 toward the outer peripheral direction of the mounting base plate 11. The triangular opening groove 23 for the prism portion is integrally formed by opening the front surface of the mounting base plate 11, and the prism portion opening groove 23 is formed as shown in FIGS. 2 and 3A. It is formed so as to circulate slightly toward the inside of the outer periphery of the plate 11. In order to increase the reflectivity of the inclined surface of the prism portion opening groove 23, it is desirable to apply a reflective paint to the inclined surface.

  Further, the outer peripheral side of the prism portion opening groove 23 of the mounting base plate 11 is a peripheral scattering portion 24 that scatters the light reflected by the prism portion opening groove 23. Accordingly, the peripheral scattering portion 24 excludes the upper side portion of the receiving front decorative plate 14 and the lower side portion of the lower ball receiving portion front decorative plate 17 as shown in substantially the entire circumference of the mounting base plate 11 (as shown in FIG. 3A). It is formed all around. In order to increase the reflectance of the peripheral scattering portion 24, it is desirable to apply a reflective paint to the surface of the peripheral scattering portion 24 that contacts the board surface of the game board 2.

  As described above, in the present embodiment, the prism base opening groove 23 that reflects the optical path a of the light emitted from the LED 22 of the LED substrate 21 toward the outer peripheral direction of the mounting base plate 11 in the mounting base plate 11. Are integrally formed on the outer periphery of the mounting base plate 11 slightly toward the inside, and the peripheral scattering portion 24 that scatters the light reflected by the prism opening groove 23 on the mounting base plate 11 outside the prism opening groove 23. Therefore, the peripheral part of the mounting base plate 11 can be uniformly decorated with light. In this case, the peripheral portion of the mounting base plate 11 can be uniformly light-decorated with a simple structure in which the prism portion opening groove 23 is formed integrally with the mounting base plate 11 and is integrally formed with the mounting base plate 11. The prism substrate opening groove 23 guides the light emitted from the rear of the mounting base plate 11 toward the peripheral portion of the mounting base plate 11, so that the LED substrate 21 provided with the LED 22 is mounted in the same manner as in the past. Since it can arrange | position facing the back of the baseplate 11, the arrangement | positioning location of the LED board 21 is not restrict | limited largely, and the shape of the prize-winning apparatus 10 is also not restrict | limited greatly. Particularly, since the opening groove 23 for the prism portion is formed so as to circulate slightly toward the inside of the outer periphery of the mounting base plate 11, it is possible to uniformly decorate the peripheral portion of the mounting base plate 11 over the entire periphery. it can.

  Next, the structure for optically decorating the upper ball guide path portion 12 and the receiving front decorative plate 14 will be described with reference to FIG. 4, at the rear end of the upper ball guide path portion 12 formed in a U-shape, as shown in FIG. 4 (C), a plurality of prism portions 27 having inclined surfaces with the passage surface as the upper end and toward the rear. Are formed at predetermined intervals, and a second LED substrate 25 on which a plurality of LEDs 26 corresponding to each prism portion 27 is mounted is attached to an outer position of the plurality of prism portions 27. The LED 26 mounted on the second LED board 25 is a side light emission type LED 26, and the light emitted from the LED 26 is reflected by the inclined surface of the prism portion 27 and is formed of a transparent synthetic resin. This is an optical path b (see FIG. 4B) that travels forward in the path portion 12. For this reason, the front end surface of the upper ball guide path portion 12 formed in a U-shape and the receiving front decorative plate 14 in contact with the upper ball guide path portion 12 are irradiated to the LED 26 to produce a light decorative effect. In this case, as described above, the surface decoration of the receiving face front decorative plate 14 is color-printed by ink-jet printing. However, by making the dot density coarser than the general density, the light transmittance is increased. Therefore, the decoration effect by the light of the receiving face front decorative plate 14 can be visually recognized more vividly than before. Note that, similarly to the above, it is desirable to apply a reflective coating to the inclined surface of the prism portion 27 in order to increase the reflectance of the inclined surface.

  Next, a configuration for optically decorating the opening / closing blade 19 as an opening / closing member will be described with reference to FIG. The opening / closing blade 19 is rotatably supported by the mounting base plate 11 by loosely fitting a rotating shaft 31 integrally projecting rearward from the lower end of the opening / closing blade 19 to the mounting base plate 11. The The opening / closing blade 19 is configured to be changed between the open state and the closed state by the solenoid 20 as described above, but in order to perform this opening / closing operation, the opening / closing blade 19 is slightly outside the rotating shaft 31. The linkage pin 32 and the solenoid 20 projecting rearward are linked by a first link member 34 and a second link member 40 which will be described later. Further, the rear end portion of the rotating shaft 31 faces the front end surface 30 a of the guiding prism body 30, and the rear end surface of the guiding prism body 30 faces the LED 29 mounted on the third LED substrate 28. ing. The third LED board 28 is provided at a position slightly ahead of the solenoid 20 located at the rearmost side of the electric chew type winning device 10. For this reason, the guiding prism body 30 that connects the LED 29 of the third LED board 28 and the rotation shaft 31 of the opening / closing blade 19 first linearly extends forward from the LED 29 on both the left and right sides of the electric chew type winning device 10. The first inclined surface portion is bent inward from the first inclined surface portion, and further bent downward from the second inclined surface portion, and then forwardly forward from the third inclined surface portion. It is configured to be bent and extended to reach 30a. Such a bending structure is employed so as not to obstruct the operation of the link members 34 and 40 that transmit the opening / closing operation of the opening / closing blade 19. The light emitted from the LED 29 is reflected by the first to third inclined surfaces of the guiding prism body 30 and guided to the rotating shaft 31 (see FIG. 5A), and the opening / closing blade 19 is reached. For this reason, the LED 29 is irradiated with the opening / closing blades 19 formed of a light-transmitting synthetic resin, thereby providing a light decoration effect. The rotating shaft 31 is a light introducing rotating shaft 31 that also has a function for introducing light emitted from the LED 29 into the opening / closing blade 19. Further, it is desirable to apply a reflective coating to the outer surfaces of the first to third inclined surfaces formed on the guiding prism body 30 in order to increase the reflectance of the inclined surfaces.

  Further, the operation of the opening / closing blade 19 will be described with reference to FIGS. 5, 6 and 7. In FIG. 6, at the rear ends of the pair of opening and closing blades 19, as described above, the light introduction rotary shaft 31 and the linkage pin 32 protrude rearward, of which the linkage pin 32 is as shown in FIG. It passes through an arc-shaped through hole 33 provided in the mounting base plate 11 and protrudes toward the rear surface side of the mounting base plate 11. The linkage pin 32 has a U-shaped engagement portion formed at the distal end portion of the first link member 34 that swings about a rotation shaft 35 that is pivotally supported in the middle of the rear side of the electric-chu winning device 10. 36 is engaged. A pair of first link members 34 are rotatably supported at both ends of the rotation shaft 35. Each of the first link members 34 is a rear vertical piece with a portion rearward of the rotating shaft 35 bent downward, and a pair of first link members 34 are provided above the rear vertical piece. An engagement connecting rod 37 to be connected is handed over (see FIGS. 5A and 5B). Further, an engaging piece 38 is formed at the lower end of the rear vertical piece so as to project inward. The engagement piece 38 is engaged with and disengaged from a notch recess 42 formed in the lower front portion of the second link member 40 fixed to the plunger 39 of the solenoid 20. The second link member 40 fixed to the solenoid 20 is fixed to the plunger 39 so as to move up and down as the plunger 39 of the solenoid 20 moves up and down. An engaging groove 41 (see FIG. 5B) is formed, and a notch recess 42 that engages and disengages with the engaging piece 38 of the first link member 34 is formed at the lower part of the front end. In the state where the opening / closing blade 19 is closed, in the loose fitting state between the engagement connecting rod 37 and the engagement groove 41, a slight clearance is generated below as shown in FIG. In the connected state of the engagement connecting rod 37 and the rear vertical piece of the first link member 34, as shown in FIG. 6B, they are connected by a long hole that causes a slight clearance upward. .

  In the opening / closing structure of the opening / closing blade 19 having the above-described configuration, when the solenoid 20 is not excited, the plunger 39 of the solenoid 20 is lowered downward as shown in FIG. The member 40 is also lowered, and in this state, the rear end side of the first link member 34 is pushed down by the engagement of the engagement groove 41 and the engagement connecting rod 37, and the first The engagement piece 38 protruding from the rear end lower portion of the first link member 34 is outside the notch recess 42 of the second link member 40 and is in contact with the front end portion of the second link member 40. Further, the U-shaped engaging portion 36 on the front end side of the first link member 34 is in a raised position (a position where the first link member 34 is in a substantially horizontal state even if it is in the raised position), As shown in FIG. 6A, the opening / closing blade 19 is centered on the light introduction rotating shaft 31 positioned below and inside the linkage pin 32 by the engagement of the U-shaped engagement portion 36 and the linkage pin 32. In addition, the opening / closing blade 19 is in a state of being rotated to a standing position, that is, in a closed state.

  Next, in the state where the solenoid 20 is excited, when the plunger 39 of the solenoid 20 rises, the second link member 40 also rises. In the initial stage of the rise, since there is a clearance between the engagement connecting rod 37 and the engagement groove 41 and the long hole of the first link member 34, only the second link member 40 is slightly raised and the clearance is reduced. When it disappears, the rear portion of the first link member 34 is pushed up by the engagement connecting rod 37 from the rotating shaft 35. At this time (when the clearance disappears), the notch recess 42 of the second link member 40 is also slightly raised, so that the engagement piece 38 at the lower end of the rear portion of the first link member 34 can enter the notch recess 42. Therefore, when the rear portion of the first link member 34 is pushed up from the rotation shaft 35 by the engagement connecting rod 37, the first link member 34 is counterclockwise as shown in FIG. The U-shaped engaging portion 36 at the tip of the first link member 34 is pushed down by rotating in the direction. When the U-shaped engaging portion 36 is pushed down, the U-shaped engaging portion 36 exerts a pressing force on the linkage pin 32, so that the opening / closing blade 19 is centered on the light introduction rotating shaft 31 and the tip of the opening / closing blade 19. Is turned outward, that is, in an open state.

  As described above, the opening / closing operation of the opening / closing blade 19 is performed by the excitation / non-excitation of the solenoid 20, but in the case of the illustrated embodiment, the solenoid 20 is not forcibly excited but forcibly by unauthorized means. The structure is such that the opening / closing blade 19 cannot be opened. That is, if the open / close blade 19 in the closed state is forcibly opened by unauthorized means, the first link member 34 is rotated counterclockwise via the linkage pin 32 as shown in FIG. The action which tries to move works. However, since the engagement piece 38 at the lower end of the rear portion of the first link member 34 is in a state of being in contact with the front end surface slightly above the cutout recess 42 of the second link member 40, the first link member 34 Since the link member 34 does not rotate counterclockwise, the opening / closing blade 19 cannot be opened. That is, the opening / closing blade 19 cannot be opened by an unauthorized means.

  The configuration and operation of the electric chew type winning device 10 provided in the game board 2 have been described above, but the open / close door type winning device 50, which is another winning device provided in the game board 2, is described with reference to FIGS.

In order to receive a game ball, a winning opening 52 formed in a rectangular shape is opened, and an opening / closing door 53 as an opening / closing member for opening / closing the winning opening 52 is provided to be changed between an open state and a closed state. The opening / closing door 53 is driven to open and close by a solenoid 54. The detailed structure will be described later in detail.

  In the present embodiment, the mounting base plate 51 and the opening / closing door 53 are formed of a transparent synthetic resin (for example, polycarbonate) having translucency, and, as will be described in detail later, by light irradiated from the LED. The light decoration effect can be demonstrated. In addition, the open / close door type winning device 50 is provided with an LED substrate 55 on which a plurality of LEDs 56 for optically decorating the peripheral portion of the mounting base plate 51 and the open / close door 53 are mounted as a configuration other than the above. .

A plurality of LEDs 56 are circumferentially mounted on the front surface of the LED substrate 55 at a predetermined interval. A prism portion opening groove 57 serving as a prism portion is located at a front position corresponding to the plurality of LEDs 56. As shown in FIG. 9C, the prism portion opening groove 57 has a cross section having an inclined surface that reflects the optical path d of light emitted from the LED 56 of the LED substrate 55 toward the outer peripheral direction of the mounting base plate 51. The triangular prism-shaped opening groove 57 is integrally formed by opening the front surface of the mounting base plate 51, and as shown in FIGS. 8 and 9A, the prism-shaped opening groove 57 is formed in the mounting base. It is formed so as to circulate slightly toward the inside of the outer periphery of the plate 51. In order to increase the reflectance of the inclined surface of the prism portion opening groove 57, it is desirable to apply a reflective coating to the inclined surface.

  Further, the outer peripheral side of the prism portion opening groove 57 of the mounting base plate 51 is a peripheral scattering portion 58 that scatters the light reflected by the prism portion opening groove 57. Therefore, the peripheral scattering portion 58 is formed on the entire circumference of the mounting base plate 51. In order to increase the reflectance of the peripheral scattering portion 58, it is desirable to apply a reflective paint on the surface of the peripheral scattering portion 58 that contacts the board surface of the game board 2.

  As described above, in the present embodiment, the prism portion opening groove 57 that reflects the optical path d of the light emitted from the LED 56 of the LED substrate 55 toward the outer peripheral direction of the mounting base plate 51 in the mounting base plate 51. Are integrally formed slightly inside the outer periphery of the mounting base plate 51, and the peripheral scattering portion 58 that scatters the light reflected by the prism opening groove 57 on the mounting base plate 51 outside the prism opening groove 57. Therefore, the periphery of the mounting base plate 51 can be uniformly decorated with light. In this case, the peripheral portion of the mounting base plate 51 can be uniformly light-decorated with a simple structure in which the prism portion opening groove 57 is formed integrally with the mounting base plate 51, and is integrally formed with the mounting base plate 51. Since the prism portion opening groove 57 guides the light emitted from the rear of the mounting base plate 51 toward the peripheral portion of the mounting base plate 51, the LED substrate 55 on which the LED 56 is provided is mounted as in the conventional case. Since it can arrange | position facing the back of the base plate 51, the arrangement | positioning location of the LED board 55 is not restrict | limited largely, and the shape of the opening-and-closing door type prize-winning apparatus 50 is also not restrict | limited greatly. In particular, the prism portion opening groove 57 is formed so as to circulate slightly toward the inside of the outer periphery of the mounting base plate 51, so that the peripheral portion of the mounting base plate 51 can be uniformly decorated over the entire periphery. it can.

  Next, a configuration for optically decorating the opening / closing door 53 as an opening / closing member will be described with reference to FIG. The open / close door 53 is pivotally mounted on the mounting base plate 51 by loosely fitting a rotary shaft 60 integrally projecting laterally at both lower ends of the open / close door 53 to the mounting base plate 51. Be supported. As described above, the open / close door 53 is configured to be changed between the open state and the closed state by the solenoid 54. In order to perform this open / close operation, the open / close door 53 is provided on the side wall of the open / close door 53 of one rotary shaft 60. The engagement notch 63 and the solenoid 54 formed are linked by a first link member 61, a second link member 65, a third link member 68, and a fourth link member 71, which will be described later. Further, the side end portion of the rotating shaft 60 faces the front end surface of the guiding prism body 59, and the rear end surface of the guiding prism body 59 faces the LED 56 mounted on the LED substrate 55. The guiding prism body 59 that connects the LED 56 of the LED board 55 and the rotation shaft 60 of the open / close door 53 has an inclined surface so that the optical path e (see FIG. 10B) of the light emitted from the LED 56 proceeds stepwise. It is comprised as the step-shaped member formed. The light emitted from the LED 56 is reflected by a plurality of inclined surfaces of the guiding prism body 59 to become an optical path e that leads to the rotating shaft 60, reaches the opening / closing door 53, and is totally reflected in the opening / closing door. It can be visually recognized by the user. For this reason, the opening / closing door 53 formed of a light-transmitting synthetic resin is irradiated on the LED 53 to provide a light decoration effect. The rotating shaft 60 is a light introducing rotating shaft 60 that also has a function for introducing light emitted from the LED 56 into the open / close door 53. In addition, it is desirable to apply a reflective paint on the outer surfaces of the plurality of inclined surfaces formed on the guiding prism body 59 and the rear surface of the open / close door 53 in order to increase the reflectance.

  Next, the operation of the door 53 will be described with reference to FIGS. In FIG. 11, the engagement notch 63 is formed on the side wall on the one rotating shaft 60 side of the opening / closing door 53 as described above. The L-shaped long side portion of the L-shaped first link member 61 that rotates about the rotation shaft 62 is inserted into the engagement notch 63 so as to be engaged. Further, an engagement protrusion 64 is provided on the L-shaped short side portion of the first link member 61 so as to be parallel to the rotation axis. The engagement protrusion 64 of the first link member 61 is engaged with a U-shaped engagement groove 66 formed at the distal end portion of the second link member 65 formed in a U-shape. The other end of the second link member 65 is connected by a connecting pin 67 to a third link member 68 that is rotatably supported by a rotating shaft 69. The third link member 68 is formed in an inverted L-shaped plate shape, and the end portion of one side of the L-shape is rotatably supported by the rotation shaft 69 and extends substantially upward from the tip end of the one side. An engagement hole 70 having a long hole shape is formed along the other side of the provided side, and the engagement is projected to a fourth link member 71 fixed to the plunger 73 of the solenoid 54. A mating pin 72 is fitted. The connection position of the second link member 65 to the third link member 68 by the connection pin 67 is a position adjacent to the rotation shaft 69.

  In the open / close structure of the open / close door 53 configured as described above, when the solenoid 54 is not excited, the plunger 73 of the solenoid 54 is pushed forward as shown in FIG. The link member 71 is also positioned forward, and in this state, the third link member 68 is stopped at a predetermined position rotated clockwise by the engagement of the engagement pin 72 and the engagement hole 70. The second link member 65 coupled to the third link member 68 is also positioned forward, and the engagement protrusion 64 that engages with the engagement groove 66 of the second link member 65 is pushed forward. Thus, the first link member 61 stops at a predetermined position rotated in the clockwise direction around the rotation shaft 62. And since the lower end part of the engagement notch 63 of the opening / closing door 53 is pressed by the long side of the 1st link member 61, the opening / closing door 53 centering on the rotating shaft 60 to FIG. 11 (A), (B). As shown, the open / close door 53 is turned to a standing position, that is, is in a closed state.

  Next, in the state where the solenoid 54 is excited, when the plunger 73 of the solenoid 54 is pulled backward, the fourth link member 71 is also pulled. When the fourth link member 71 is pulled in, the third link member 68 rotates counterclockwise about the rotation shaft 69 due to the engagement between the engagement pin 72 and the engagement hole 70, and this third link member The second link member 65 connected to 68 is also pulled in, and the first link member 61 also rotates counterclockwise about the rotation shaft 62 due to the engagement between the engagement protrusion 64 and the engagement groove 66. Then, since the long side portion of the first link member 61 is not pushed downward to the engagement notch 63, the open / close door 53 is rotated forward by its own weight about the rotation shaft 60, that is, opened. It becomes a state.

  As described above, the opening / closing operation of the open / close door 53 is performed by the excitation / non-excitation of the solenoid 54. However, in the illustrated embodiment, the solenoid 54 is not forcibly excited but forcibly by an unauthorized means. The structure is such that the opening / closing door 53 cannot be opened. That is, if the open / close door 53 in the closed state is forcibly opened by unauthorized means, the second link member 65 is shown in the left side of the figure via the first link member 61 as shown in FIG. The action to move in the direction works. However, since the second link member 65 has a “h” shape, the acting force on the connecting pin 67 that connects the second link member 65 and the third link member 68 is the “h” shape side. This is an obliquely downward left direction along the portion, and thus acts as an action force for rotating the third link member 68 in the clockwise direction. That is, the door 53 cannot be opened because it only acts in the direction in which the fourth link member 71 is not pulled in, but in the direction in which it is pulled out. That is, the open / close door 53 cannot be opened by unauthorized means.
