  The movable main body 28 has a front-side movable part 28a and a rear-side movable part 28b which are split into two, and the front-side movable part 28a and the rear-side movable part 28b are integrated by screwing. Both the front-side movable part 28a and the rear-side movable part 28b are molded products of synthetic resin, and a hollow cover 33 is integrally formed at the tip of the front-side movable part 28a. The movable main body 28 and the cover 33 serve as a movie projector, and the rear end of the movable main body 28 is rotatably connected to the arm portion 27b of the support 27 via a support shaft 34. A torsion coil spring 35 is wound around the support shaft 34, and one arm portion 35a of the torsion coil spring 35 is hooked to the front side movable portion 28a, and the other arm portion 35b is hooked to the arm portion 27b. By being stopped, the movable main body 28 is elastically biased in the clockwise direction of FIG. Although detailed description will be given later, the rotation angle of the movable main body 28 is determined by the rear end portion of the back side movable portion 28b coming into contact with the drive pin 29c of the operating body 29, that is, depending on the slide position of the operating body 29. Is defined within a predetermined range (arrow θ in FIG. 10) between the initial position and the operation position.

  A first circuit board 36 and a second circuit board 37 are disposed in the movable main body 28 in a posture orthogonal to each other. A plurality of LEDs 38, circuit elements, and connectors are mounted on the first circuit board 36, and the first circuit board 36 is connected to the relay board 42 described above via a flat cable (not shown). A light guide 39 is sandwiched and fixed between the first circuit board 36 and the front side movable portion 28a, and a plurality of protrusions 39a are formed on the light guide 39. These protrusions 39a are inserted into the through holes of the front-side movable part 28a, and when the LED 38 is turned on, the light is emitted from each protrusion 39a to the front of the front-side movable part 28a. On the other hand, an LED 40 and a connector as a light source are mounted on the second circuit board 37, and the first circuit board 36 and the second circuit board 37 are connected to each other through a wire harness (not shown). . The motor 24 and the relay board 42 described above are connected to a control board (not shown) provided on the back side of the game board 3 via a wire harness, and the first is based on the control signal of this control board. The LEDs 38 and 40 on the second circuit boards 36 and 37 are turned on, and the rotation direction and the rotation amount of the motor 24 are controlled.

  Further, a lens 41 is disposed inside the movable main body 28, and this lens 41 is located in front of the LED 40. The surface of the lens 41 is exposed at the bottom of the cover 33, and the cover 33 is disposed so as to surround the lens 41. The cover 33 has a hollow structure with an open front end, and its external shape is a quadrangular pyramid that expands from the bottom toward the front end. As shown in FIGS. 9 and 10, a plurality of ribs 33 a are formed on the four inner side surfaces of the cover 33 so as to protrude at predetermined intervals, and these ribs 33 a extend radially around the lens 41. . For example, silver paint is applied to each inner side surface and bottom surface of the cover 33 as a light diffusion process.

  As shown in FIGS. 11 and 12, the lens 41 has an external shape that swells in a circular bowl shape, and its thickness gradually increases from the central part toward the outer peripheral part. A plurality of flat portions 41a and sawtooth portions 41b are alternately formed concentrically on the exit surface of the lens 41. When the LED 40 is turned on, the light passes through the flat portions 41a and the sawtooth portions 41b. Then, the light is emitted into the cover 33. At that time, as indicated by a solid line in FIG. 12, part of the light of the LED 40 passes straight through the flat portion 41 a and is emitted outward from the opening end of the cover 33 as it is. Also, as indicated by the alternate long and short dash line in FIG. 12, some of the light from the LED 40 toward the sawtooth portion 41 b is refracted by the sawtooth portion 41 b and is emitted as it is toward the inner surface of the cover 33, and some is the lens 41. After the irregular reflection is repeated inside, the light is emitted from the sawtooth portion 41 b toward the inner surface of the cover 33. And since some diffused light radiate | emitted from the lens 41 is reflected by the rib 33a formed in each inner surface of the cover 33 in this way, and the remainder is reflected by the inner surface where the rib 33a does not exist, both Due to the difference in reflectance, contrast between light and dark can be given to the inner surface of the cover 33.

  Next, the operation of the movable accessory device 13 configured as described above will be described with reference to FIGS.

  In the movable accessory device 13 according to the present embodiment, the movable main body 28 is normally at the home position shown in FIGS. 4 to 9. When this home position is called the initial position, as shown in FIG. The movable main body 28 stands by at the upper right corner of the display screen 14a of the variable display device 14. In this case, the support 27 that supports the movable body 28 is raised to the upper end of the guide rail 26 (the end position in the arrow Y1 direction), and the movable body 28 is shown in FIG. 10 by the elastic force of the torsion coil spring 35. It is held in a posture, that is, a posture in which the front-side movable part 28a faces the glass door 4 and the opening end of the cover 33 faces leftward. In addition, when the LED 38 on the first circuit board 36 is turned on in such a state, the light of the LED 38 is emitted from each protrusion 39a of the light guide 39 to the front side of the front side movable portion 28a. By emitting light from each protrusion 39a toward the glass door 4, it is possible to make the player suggest that there is a higher possibility of a big hit than usual.

  Thus, when the motor 24 is rotated in one direction when the movable body 28 is in the initial position, the rotation of the motor 24 is transmitted to the gear train 25 via the reduction gear unit 31, so that the final gear of the gear train 25 The rack 27 a meshing with the linear movement moves linearly, and accordingly, the support body 27 starts to move downward along the axial direction of the guide rail 26. Here, in the initial stage in which the support body 27 descends in the Y2 direction from the uppermost end position in the arrow Y1 direction, the movable body 28 maintains the posture in which the front side movable portion 28a is directly facing the glass door 4. However, when the support body 27 is lowered by a predetermined amount, the engagement pin 29b of the operating body 29 is lowered while contacting the inclined portion 23a of the holding case 23 as shown in FIGS. Then, the operating body 29 starts to slide in the X2 direction from the end position in the arrow X1 direction in FIG. As a result, the drive pin 29c of the operating body 29 presses the rear end portion of the rear side movable portion 28b, so that the movable body 28 counterclockwise from the initial position in FIG. 10 against the elastic force of the torsion coil spring 35. 15 and 16, when the support 27 moves to the lowermost position in the direction of arrow Y2 and the engagement pin 29b gets over the inclined portion 23a, the operating body 29 moves in the direction of arrow X2. The movable body 28 is rotated to the operating position by moving to the end position.

  That is, the movable main body 28 that has been waiting at the upper right corner of the display screen 14a in the initial position is located in the direction of the arrow Y2 in FIG. 2 while maintaining the posture in which the front-side movable portion 28a faces the glass door 4. After descending by a certain amount, the entire structure including the cover 33 is lowered to the lowermost position shown in FIG. 3 with the swinging motion of rotating to the near side. It becomes the posture which opposes from the back. Therefore, if the LED 40 on the second circuit board 37 is turned on during the lowering operation of the movable main body 28, the movable main body 28 is lowered with the opening end of the cover 33 facing the left side. By swinging the movable body 28 and directing the opening end of the cover 33 to the player, a novel lighting effect can be performed in which dazzling light is suddenly emitted from the cover 33 of the movable body 28 that is lowered.

  Here, in the movable accessory device 13 according to the present embodiment example, the flat portions 41a and the sawtooth portions 41b are alternately formed concentrically on the emission side surface of the lens 41 disposed in front of the LED 40, and thus flat. Since the light straightness by the portion 41a and the light diffusibility by the sawtooth portion 41b can be combined, a plurality of ribs 33a extending radially are formed on each inner wall surface of the cover 33. The emitted diffused light of the LED 40 can be reflected by the ribs 33a to give a contrast of light and dark. As a result, the player sees the diffused light that shines brightly at the opening end of the cover 33 and the straight-ahead light from the LED 40 at the same time, and gives out a glaring feeling over a wide range with the light emitted from one lens 41. Can do. Thus, for example, when the movable accessory device 13 is operated during super reach, the possibility of a big hit is very high due to both the movable aspect in which the movable main body 28 rotates while descending and the lighting effect by the irradiation light from the cover 33. Can be suggested to the player.

  When the movable main body 28 is at the lowermost position shown in FIG. 3, when the motor 24 is rotated in the other direction, the reverse operation is performed. In this case, in the initial stage in which the support body 27 rises in the Y1 direction from the lowest end position in the arrow Y2 direction, the engaging pin 29b of the operating body 29 slides on the inclined portion 23a of the holding case 23 from the bottom to the middle. Thus, the movable body 28 is rotated and returned from the operating position to the initial position by the elastic force of the torsion coil spring 35. Thereafter, while the support body 27 is raised to the uppermost position in the direction of the arrow Y1, the movable main body 28 is lifted together with the support body 27 while maintaining the posture in which the front side movable portion 28a is directly opposed to the glass door 4, Finally, it returns to the initial position (home position) shown in FIG.

  In the above embodiment, a pair of guide rails 26 are fixed to the bracket 22 in parallel with each other at a predetermined interval, and the support body 27 is guided in the vertical direction by the two guide rails 26. It is also possible to use other configurations as the guide means of the support 27, such as using a concave-convex fitting instead of the guide rail 26.

  In the above embodiment, the housing 30 is formed by integrating the bracket 22 and the holding case 23, and the operating body 29 is slid by the inclined portion 23a formed in the holding case 23. Such an inclined portion may be formed on the bracket 22 instead of the holding case 23, or the housing may be formed of a single member and the inclined portion may be formed on the member.
