Description

  The present invention relates to a speaker unit and a gaming machine.

  In gaming machines such as pachinko machines, a game board is detachably assembled to an inner frame that can be opened and closed with respect to an outer frame. The inner frame is provided with a front frame that can be opened and closed. In the central window of the game board, a symbol display device (liquid crystal display device) is provided, and around it, board parts such as rails, nails, through chuckers, chuckers, windmills, attackers, electric tulips, etc. and outro are provided. ing.

  A window portion is formed at the center of the front frame, and a transparent plate (a glass plate, a transparent resin plate, etc.) is provided on the window portion. In addition, around the window portion, a decoration portion such as a decoration member incorporating a light emitting unit or a speaker for outputting sound is provided. For the decorative member, for example, a light transmissive resin material (polycarbonate resin material, acrylic resin material, etc.) is used. In order to enhance the effect of light and sound such as a decoration effect by lighting display of a decoration member provided in the decoration part and a sound effect output from a speaker, a gaming machine described below has been proposed.

  For example, a game in which the LED board is placed in an area other than the placement position of the speaker, and the lens cover, speaker, and speaker mounting cover are detachably attached to the transparent plate holding frame to enhance the decorative effect around the speaker A machine has been proposed (see Patent Document 1).

In addition, an indicator lamp board is attached to the frame behind the acoustic unit in which an acoustic speaker is assembled in a box-type container that is a combination of a front unit container and a rear unit container made of a light transmissive resin material, and the indicator lamp emits light. There has also been proposed a gaming machine in which irradiation light is diffusely reflected by an uneven surface provided in the acoustic unit to irradiate the acoustic unit with light from behind (see Patent Document 2).
Japanese Patent Laid-Open No. 11-333060 JP 2007-175123 A

  However, since the gaming machine of Patent Document 1 described above is provided with the LED substrate in the peripheral region excluding the speaker placement region, the installation area of the unit including the speaker becomes large, and the degree of freedom in designing the decorative portion is limited. There is a problem that it is easy to receive. In addition, the unit such as the lens cover and the speaker and the LED substrate are individually attached to the transparent plate holding frame, and therefore, the number of assembling steps is large and labor is required.

  In addition, the gaming machine of Patent Document 2 is configured to illuminate the box-shaped container by turning on the indicator lamp on the display lamp substrate from behind the box-shaped container in which the acoustic speaker is built. However, since the front unit container is provided with a punching metal and a decorative body, the lighting effect visually recognized by the player is indirect and weak, and an indicator lamp board and an acoustic speaker are attached to the frame. The built-in unit containers must be stacked and assembled in this order, which requires a lot of assembly work and labor.

  Further, in consideration of the acoustic effect of the speaker, it is preferable not to provide a shield in front of the speaker. However, when viewed from the player side, the decoration effect by light is reduced for the installation area of the speaker. Thus, there has been a need to overcome the structural problems that conflict with the effects of the gaming machine and to further improve the effects.

  An object of the present invention is to provide a small speaker unit that improves the decorativeness of a speaker installation area and improves the assembling property to a gaming machine, and a gaming machine including the speaker unit.

In order to achieve the above object, the present invention comprises the following arrangement.

It is characterized by being assembled in one piece.

  The decorative member irradiated with light from the light emitting means is housed in the case body.

  Further, at least one of the front and rear of the speaker housed in the case body is provided with a decorative member made of a light transmissive resin material that is irradiated with light by the light emitting means.

  In addition, in the gaming machine, any one of the above-described speaker units is assembled to the front frame as a part of a decorative portion provided around a window portion through which the game board is seen.

  Further, the front frame is provided with a reflecting portion for reflecting the irradiation light from the light emitting means.

  If the above-described speaker unit is used, the speaker and the light emitting means are integrally assembled in the case body, so that the speaker unit can be attached to a gaming machine with a small area, and the light emitting means irradiates the case body with light. This makes it possible to enhance the decoration effect of the speaker installation area.

  Further, when the decorative member irradiated with light by the light emitting means is housed in the case body, the light irradiated by the light emitting means shines the decorative member, and the decorative effect of the case body visible from the outside can be enhanced.

  In addition, since at least one of the front and rear of the speaker accommodated in the case body is provided with a decorative member made of a light-transmitting resin material that is irradiated with light from the light emitting means, the decorative member emits light to the player side. Can be directly or indirectly visually recognized through the case body and the front frame.

  Also, in a gaming machine, when the above-described speaker unit is assembled to the front frame as a part of a decorative portion provided around the window portion through which the game board is seen, the speaker unit is small and decorative in the speaker unit installation area. As a result, the assembly man-hours can be reduced. In addition, since the speaker unit includes the light emitting means, a variety of effects can be obtained by combining with the light emission mode of the decorative member assembled to the front frame and with the sound output from the speaker.

  In addition, if the front frame is provided with a reflective part that reflects the light emitted from the light emitting means, the combination of the decorative effect by the light irradiation to the front of the speaker unit and the decorative effect by the reflected light from the reflective part, A synergistic decoration effect is born by the shade of the.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
A schematic configuration of the gaming machine according to the present embodiment will be described with reference to FIG. In this embodiment, a pachinko machine will be described as an example of a gaming machine. The gaming machine 1 includes an inner frame (not shown) in which an outer frame 2 and a game board 3 are provided, and a front frame 4 that covers the inner frame. An inner frame (not shown) is attached to the outer frame 2 by a hinge 5 so as to be opened and closed. The front frame 4 is attached to the inner frame so as to be openable and closable (the hinge portion is not shown). A window 4 a through which the player can see through the game board 3 is provided at the center of the front frame 4. A decorative portion A is provided around the window portion 4a. The decorative portion A is provided with a speaker unit 6 described later, a decorative cover 7 made of a light-transmitting resin material, and the like.

A central window 3a is formed in the game board 3. The central window portion 3a is a concave surface portion or an opening portion, and a symbol display device 11 and a decorative member 12 provided in a back unit (not shown) are disposed so as to be visible.

  In this example, a transparent resin plate is used, and the transparent resin plate is provided with a strip-like light emitting portion 3b. The strip-shaped light emitting portion 3b is formed by engraving a line-shaped pattern on the back side of the transparent resin plate. The belt-like light emitting portion 3b emits light by light incident from a light source provided on the end surface of the transparent resin plate. In the case of using a veneer plate, the band-like light emitting portion 3b is formed by assembling the lens together with the surface parts. The belt-like light emitting portion 3 b is formed to be a continuous pattern with the partition plate 21 that partitions the interior of the decorative cover 7. On the front surface side of the transparent resin plate, panel parts such as a nail 13, a through chucker 14, a chucker 15, a windmill 16, an attacker 17, an electric tulip 18, a rail 19, and an outro 20 are provided.

  Here, the configuration of the decorative portion A will be described with reference to FIGS. 2 is a perspective view showing the configuration of the upper right corner portion when the gaming machine 1 of FIG. 1 is viewed from the front, FIG. 3 is a partially broken perspective view of FIG. 2, and FIG. 4 is a cross-sectional view of a decorative portion A including a partition plate, FIG. 5 is an exploded perspective view of the decorative portion A. FIG. In FIG. 2, the front side of the decorative portion A is covered with a hollow frame-shaped decorative cover 7 using a light-transmitting resin material (polycarbonate resin material, acrylic resin material, etc.). In FIG. 3, the speaker unit 6 is assembled in the vicinity of the corner portion of the base portion 30.

  In FIG. 2, a small hole opening portion 7 a and an opening portion 23 are provided on the surface portion of the decorative cover 7 at the facing portion of the speaker unit 6. A partition area 22 partitioned by a plurality of partition plates 21 is provided inside the decorative cover 7. For the partition plate 21, a light transmissive resin material (polycarbonate resin material, acrylic resin material, etc.) is preferably used. In the partitioned area 22 partitioned by the partition plate 21, the speaker unit 6 is disposed to face the small hole opening 7 a, and the speaker 24 is provided to face the opening 23.

  In FIG. 3, each speaker 24 is integrally assembled with a cover body 24a having a small hole formed on the front side of the speaker body 24b by locking the claw portion 24c to the speaker body 24b. Each speaker 24 unitized in this manner is engaged with a hook 23 a provided at the peripheral edge of the opening 23 so as to close the opening 23 and is assembled to the decorative cover 7.

  3 and 4, a light emitting substrate 25 (light emitting means) is assembled to the base portion 30. The light-emitting board 25 has a light source 26 for a partition plate (see FIG. 4) that irradiates light from the end surface of the partition plate 21 to the front of the gaming machine, and each partition area 22 partitioned by the partition plate 21 has a front of the gaming machine. A partition area light source 27 for irradiating light is provided (see FIG. 3). Monochromatic or full-color LEDs are preferably used for the light source 26 for the partition plate and the light source 27 for the partition area. The partition light source 26 and the partition light source 27 may be provided on different substrates. In addition, the light source 26 for the partition plate and the light source 27 for the partition area are provided so as to irradiate light toward the front of the gaming machine. However, the present invention is not limited to this arrangement configuration, and the partition plate light source 26 uses the partition plate 21. The partitioned area light source 27 may be provided so as to irradiate each of the partitioned areas 22 with light.

  Thus, by arranging a plurality of light sources on the same light emitting substrate 25, the number of parts and the installation area can be reduced, and the decoration portion A can be reduced in size. Moreover, since the area of the window part 4a can be enlarged by reducing the size of the decoration part A, the area that can be visually recognized from the player side can be expanded corresponding to the widening of the game area. In addition, since the light emitting substrate 25 is provided with the light source 26 for the partition plate that irradiates the partition plate 21 with light, the decoration effect is enhanced by irradiating light from the end surface of the partition plate 21 that normally becomes a decorative dead space to the front of the gaming machine. be able to. Further, various decoration effects can be obtained by irradiating the inside of the partition area 22 with the light source 27 for the partition area and irradiating the end face of the partition plate with the light source 26 for the partition board, and changing the combination of the light emission mode and the emission color. As a result, the production effect can be enhanced.

  In FIG. 3, reflection surfaces (mirror surfaces) 28 for reflecting the irradiation light of the partition plate light source 26 are provided on both side surfaces in the plate thickness direction of the partition plate 21. Thereby, the irradiation light of the partition plate light source 26 incident from the end face of the partition plate 21 does not diffuse into the partition region 22. Therefore, since the light incident from the partition plate light source 26 in the thickness range of the partition plate 21 can be clearly seen from the player side, the decoration of the decoration portion A can be enhanced. Further, the partition plate 21 may be engraved or the like for diffusing light incident on side surfaces other than the end surfaces. In addition, the reflective surface 28 can also reflect the light of the partition region light source 27 by using a seal or the like whose both surfaces are mirror surfaces. Further, the reflecting surface 28 is not limited to a planar shape, and may be a curved surface shape or an uneven surface shape.

  In FIG. 3, a reflector (reflector) 29 a is provided on the back side of the speaker unit 6 to reflect the light emitted from the light emitting means provided on the speaker unit 6 toward the front side of the gaming machine. Yes. Further, a diffusion plate 29 b (diffusion part) is provided on the back side of the partition region 22. The diffusing plate 29 b allows the irradiation light of the partition region light source 27 to be seen through and diffuses the incident light to each partition region 22. Thus, since the irradiation light of the partition area light source 27 can be diffused by the diffusion plate 29b, the entire partition area 22 can be brightly irradiated with a small number of partition area light sources 27.

  In FIG. 4, the diffusion plate 29 b is not provided at a portion facing the end surface of the partition plate 21 so that the light emitted from the light source 26 for the partition plate is directly incident on the end surface. Alternatively, the speaker unit 6 may be irradiated with the diffuser plate 29b and the partition region light source 27 disposed on the back side of the speaker unit 6. Further, the reflecting plate 29a and the diffusing plate 29b may be those obtained by secondary processing of a resin plate (seal sticking, paint coating).

  As described above, when the speaker unit 6 and the speaker 24 that output sound are provided in each partition region 22, the sound output from the speaker unit 6 and the speaker 24 and the light emission mode of the end surfaces of the partition region 22 and the partition plate 21 are provided. By combining, various visual and auditory effects can be obtained.

Here, an example of the assembly configuration of the decorative portion A will be described with reference to FIG.
Sheet metals 30a and 30b are screwed to the back side of the L-shaped base portion 30 in the vertical and horizontal directions to be reinforced. A light emitting substrate 25 is screwed to the front side of the base portion 30. The light emitting substrate 25 is assembled outside the installation area of the speaker unit 6.

  The partition plate 21 is screwed to the end surfaces of the reflecting plate 29a and the diffusing plate 29b at predetermined positions. The reflection plate 29a to which the partition plate 21 is screwed is assembled by being aligned by inserting a boss portion 30c protruding from the base portion 30 into the through hole 29c (see FIG. 3). Further, the diffusion plate 29 b to which the partition plate 21 is screwed covers the light emitting substrate 25 and is screwed to the base portion 30. The speaker unit 6 is fixed by screwing the boss 34b on the back side with the boss 30c of the base 30 (see FIG. 3). Further, the speaker 24 is engaged with a hook 23 a provided at the peripheral edge of the opening 23 so as to block the opening 23 and is assembled to the decorative cover 7 so that the decorative cover 7 covers the base 30. They are assembled together (see FIG. 3). The assembly structure between the members is not limited to screwing, and other assembly structures such as bonding and fitting may be used.

Next, a specific configuration of the speaker unit 6 will be described with reference to FIGS. 6, the speaker unit 6 houses a speaker 32 that outputs sound to a case body 31 made of a light-transmitting resin material, and a light emitting substrate 37 (light emitting means; see FIG. 7) that emits light toward the case body 31. ing. Thus, since the speaker 32 and the light emitting substrate 37 are integrally assembled in the case body 31, the assembly area of the speaker unit 6 with respect to the gaming machine 1 (see FIG. 1) can be reduced and the light emitting substrate can be reduced. Since 37 irradiates the case body 31 with light and makes it shine, the decoration effect of a speaker installation area | region can be heightened.

The second decorative member 36 may be formed with textures, knurling, or engraved patterns to diffusely reflect the irradiation light from the light emitting substrate 37, or may be colored in whole or in part. Also good. Since the light emission mode of the second decorative member 36 can be directly or indirectly visually recognized by the player side through the case body 31, the reflecting plate 29, and the decorative cover 7, the decorative effect is enhanced. In addition, the decoration member should just be provided in any one of the front of the speaker 32, or back.

  A first light source 38 for irradiating the first decorative member 35 with light is provided on the front surface of the light emitting substrate 37 accommodated in the case body 31, and the second decorative member 36 is irradiated with light on the back surface of the light emitting substrate 37. A second light source 39 is provided. As the 1st light source 38 and the 2nd light source 39, single color or full color LED is used suitably. Thus, by arranging the light sources on both surfaces of the light emitting substrate 37, the number of components is reduced, and the speaker unit 6 can be downsized. When the first light source 38 is turned on, the irradiation light is guided in the circumferential direction through the light guide tube 40 and is emitted in a ring shape as a whole. Further, when the second light source 39 is turned on, the irradiated light is diffused to the surroundings through the second decorative member 36 or reflected on the reflecting plate 29a (see FIG. 3), so that the reflected light can be visually recognized from the front side of the gaming machine. It is like that.

  In FIG. 7, the second decorative member 36, the light emitting substrate 37, the speaker 32, and the first decorative member 35 are integrally assembled by a set screw 42. Further, the flange portion 36 a of the second decorative member 36 is sandwiched between the first case body 33 and the second case body 34.
