Description

The present invention relates to a gaming machine capable of displaying information such as symbols and images.

(Exemplary Related Technology) As a known technology related to this type of gaming machine, there is a gaming machine including a variable display device that variably displays identification information (for example, see Patent Document 1). This variable display device includes a plurality of (for example, nine) rotating drums, and decorative symbols corresponding to special symbols are attached to the surfaces of the rotating drums. The variable display device can variably display decorative symbols by rotating a rotating drum, and can variably display special symbols and normal symbols by a 7-segment LED or the like.

In the variable display device, each rotating drum is driven by a stepping motor, and these stepping motors are stored in a drive unit storage box in a state of being arranged on a mounting substrate. An illumination lamp is disposed inside the rotary drum, and a decorative pattern on the surface of the rotary drum is lit and displayed by light transmitted through the lamp.

(Characteristics of publicly known technology) Since the above-mentioned variable display device uses a large number of mechanical and electrical devices serving as various heat sources such as stepping motors, power supply / relay boards, lamps, etc., the heat generated by these devices is variable. There is a possibility of adversely affecting each other in the display device.

For this reason, in a known gaming machine, a rotating drum of a variable display device, a stepping motor, its power supply / relay board, a lamp, and the like are housed in a housing case, and the inside is cooled by a cooling device.
JP-A-9-308735 (page 2-3, FIG. 11, FIG. 12)

(First Problem) In a known gaming machine, since the inside of the storage case can be cooled in a lump, it is considered unnecessary to individually cool each device stored in the storage case. However, all the devices that serve as heat sources are stored in the storage case, and most of the heat released from each device stays in the storage case. . Of course, although the inside of the housing is cooled by the cooling device, the extent to which the heat staying in the housing is removed depends greatly on the performance of the cooling device. For this reason, if the performance of the cooling device cannot keep up with the amount of heat generated by the entire device, a sufficient cooling effect cannot be obtained. Conversely, if the inside of the housing is sufficiently cooled, a considerably high-performance cooling device is provided. There is a problem that costs increase due to necessity.

Accordingly, an object of the present invention is to provide a technique capable of taking a sufficient heat countermeasure without using a particularly high-performance cooling device or the like.

(Second Problem) In addition, in a known gaming machine, a vent hole is formed in the mounting substrate of the rotating drum and the stepping motor, so that a plurality of rotating drums are in close proximity to each other in the storage housing (drive unit storage box). Even if it is housed, it is considered that the space between the rotating drums is easily cooled. However, it is only the outside of the rotating drum that is cooled inside the housing (see FIG. 11 of Patent Document 1, paragraph number 0049, etc.), and when the individual rotating drum is viewed alone, the inside thereof is hardly cooled. . For this reason, in a known gaming machine, there is a bias in a portion that is easily cooled, and there is still a possibility that an adverse effect due to heat may still occur in a lamp or the like inside the rotating drum that is not easily cooled.

Therefore, an object of the present invention is to provide a technique capable of realizing an even effective heat countermeasure for various parts of equipment.

In this invention, said 1st subject is solved by improving the heat dissipation (heat dissipation amount, heat dissipation efficiency, etc.) from the apparatuses used as various heat sources.

(Solution 1) For this reason, the gaming machine of the present invention has a display screen formed on the surface, and the display screen is arranged toward the front side of the gaming machine main body, and the back of the display unit. In a state of being opposed to each other, the control unit is disposed with a predetermined gap between the control unit and the control unit for controlling the operation of the display unit, and between the display unit and the control unit. A heat radiating air layer formed and capable of releasing heat generated from each of these units, and a ventilation means for ventilating by generating an air flow in the heat radiating air layer are provided.

In the above configuration, a heat radiation air layer is formed in the space between the display unit serving as a heat source and the control unit, that is, outside these units, and heat emitted from each unit can be released to this heat radiation air layer. ing. Furthermore, since the air in contact with each unit is constantly exchanged by ventilating the inside of the radiating air layer, the amount of heat radiated from each unit to the radiating air layer, the heat radiating efficiency, etc. can be greatly improved. .

(Solution 2) The gaming machine of the present invention may have an independent aspect. In this case, the gaming machine of the present invention has a display screen formed on the surface as its configuration, and the display screen faces the display unit arranged toward the front side of the gaming machine body and the back of the display unit. The display unit and the control unit, which are arranged in a connected state and equipped with a control device for controlling the operation of the display unit, are connected to each other at a predetermined interval. A connecting member that forms a radiating air layer capable of releasing heat generated from each unit with the outer surface of the control unit, a fan device that ventilates by generating an air flow in the radiating air layer, and a display unit or control Formed on at least one of the units, with the display unit and the control unit connected to each other by a connecting member, the fan device is sandwiched between these units and supported Has become that a that the mounting portion.

In this case as well, as in the above solution 1, a radiating air layer is formed between the display unit and the control unit, and the inside of the radiating air layer is ventilated by the fan device. Heat dissipation efficiency can be improved.

In addition, in the solution means 2, only by connecting the display unit and the control unit by the connecting member, a radiating air layer is formed between them, and the fan device is supported between the two units. The In the solution 2, the “attachment portion” can take the following two modes. (1) The “mounting portion” is integrally formed with both the display unit and the control unit. When these two units are connected by a connecting member, the fan device is mounted by the mounting portion formed in each unit. Supported. (2) Alternatively, the “mounting portion” is formed integrally with either the display unit or the control unit and the connecting member. In this case, when the two units are connected by the connecting member, the fan device is supported by the attaching portion formed on one of the two units and the attaching portion formed on the connecting member.

In any of the above embodiments, the fan device is supported between the two units by simply connecting the display unit and the control unit. For this reason, when assembling the gaming machine, it is not necessary to individually attach the fan device to the display unit or the control unit, and the workability can be improved, and the number of parts for mounting can be reduced. Can do.

(Solution 3) In the above solution 2, a vent hole is formed in at least one outer peripheral surface of the display unit or the control unit, and the fan device has a vent hole whose blade rotation area is formed in the unit outer peripheral surface. It is preferable that the inside of at least one of the display unit and the control unit can be ventilated.

Display units, control units, etc. are usually equipped with electronic devices / equipment for transmitting control signals and performing logical operations, so the amount of heat generated by the operation of various devices / equipment inside these units. It can be said that there is a lot of adverse effects due to heat (such as CPU runaway). For this reason, in addition to ensuring ventilation by forming ventilation holes on the outer peripheral surface of each unit, the inside of the unit is efficiently ventilated by arranging the blade rotation area of the fan device so as to overlap the ventilation holes. It becomes possible. Thereby, since the heat radiation efficiency is improved even inside the unit, it is possible to effectively prevent the electronic device / equipment from being adversely affected.

In the solution 3, the “outer peripheral surface” includes the upper end surface, the lower end surface, the side surface, and the like of each unit. In addition, the vent hole may be formed on the “outer peripheral surface” in either the display unit or the control unit, or the vent hole may be formed in both and the inside of both units. May be a mode that can be ventilated by a fan device.

(Solution 4) The above display unit displays symbols and images on its display screen. By adding a display operation by an effect operating body to the display unit, it is possible to further enhance the effect during the game. it can.

Therefore, in the above solutions 1 to 3, the gaming machine of the present invention is arranged adjacent to the display screen, and has an effect operating body that performs an effect operation as viewed from the front side of the gaming machine main body together with the display screen. The effect operation unit is formed between the effect operation unit that supports the display operation unit along the outer peripheral surface of the display unit with a certain interval, and between the outer peripheral surface of the display unit and the effect operation unit. An aspect may further include an air flow passage that circulates air in a direction around the back surface and communicates with the radiating air layer.

The above-mentioned “production operation body” includes those that perform the production operation by displaying symbols and images in the same manner as the display screen, or by a movable object such as a drum or a reel, or an accessory device having a movable part. The thing which performs production operation is also included.

In any case, since an electronic circuit and a drive source are required to perform the rendering operation by the rendering operation body, there is considerable heat generation from the rendering operation unit as well as the display unit and the control unit. In this case, if the effect operation unit and the display unit are arranged close to each other, heat tends to stay between them, and there is a possibility that both of them have an adverse effect due to heat. On the other hand, it is necessary to arrange the display screen and the production operation body close to each other in order to improve the visibility from the player or to realize the visual display / production integration. Therefore, it is practically not preferable to dispose the display unit and the effect operating body at positions extremely away from each other in order to avoid the influence of heat.

For this reason, in the solution means 4, an air flow passage is formed between the outer peripheral surface of the display unit and the rendering operation unit, and the air flow is caused to flow from the outer peripheral surface of the display unit to the back through the air flow passage. Thus, it is possible to effectively prevent heat from being retained between the two. In addition, the airflow which circulated from the outer peripheral surface of the display unit to the back surface joins the radiating air layer as it is, and is subject to ventilation by the ventilation means (fan device).

(Solution means 5) Next, in this invention, said 2nd subject is solved by also improving the heat dissipation (heat dissipation amount, heat dissipation efficiency, etc.) from the inside of a production | presentation action body.

When performing a stunning display using a staging body in a gaming machine, a mode using a movable body such as a drum or a reel is particularly suitable for variably displaying symbols and the like. For this reason, in the solution means 4 described above, the effect operating body includes a drum-shaped main body rotated around a predetermined axis, an opening formed at one end of the drum-shaped main body and opening the inside thereof, and other drum-shaped main bodies. A hub portion provided at the end and connected to the rendering operation unit; and a vent hole formed in the hub portion and communicating with the inside of the drum-shaped body. The rendering operation unit is one end of the drum-shaped body. In this state, the drum-shaped main body is formed as an outside air introduction path that guides the outside air to at least one of the air flow path and the heat radiating air layer. ing.

When the production operation body is configured as a drum as described above, the air permeability to the air flow path between the display unit and the production operation unit is improved by using the space inside the production operation body as a ventilation duct. In addition, the air permeability inside the production operation unit can be improved. In this case, since it is difficult for heat to stay in the production operation unit alone, adverse effects due to heat from the drive source or the like can be effectively prevented.

(Solution 6) In the above solution 5, the gaming machine of the present invention is disposed inside the drum-shaped main body of the production operation body, and emits decorative light from the inside toward the front side of the production operation body. It may be an aspect further provided.

In the above aspect, the symbols and the like attached to the outer peripheral surface of the drum-shaped main body are lit and displayed with the decoration light as the backlight (transmitted light), so that the player feels as if the symbols and the like are emitting light. A visual effect is obtained. On the other hand, when the light source is arranged inside the drum-shaped main body, the heat generated from the light source tends to stay in the structure, and the light source may cause a light emission failure due to an adverse effect due to the heat.

Even in such a case, in the above solution 5, in the present invention, the inside of the drum-shaped body is formed as an outside air introduction path, and the periphery of the light source is always ventilated by the circulation of the outside air. It is possible to effectively prevent heat from staying in the interior of the light source and to adversely affect the light source due to heat, and to improve the heat radiation efficiency from the light source. Therefore, it is possible to stably produce the decoration light using the light source in the production operation unit.

(Solution means 7) By the above solution means 1-6, it has become clear that the heat dissipation from various units is improved in the present invention, and that these are effectively prevented from being adversely affected by heat. Apart from this, in the present invention, the improvement of the decorative effect can be realized from another viewpoint.

For example, in the solving means 4 to 6 described above, the space between the outer peripheral surface of the display unit and the effect operation unit is used as an air flow path, and the inside of the drum-shaped main body of the effect operation body is the outside air introduction path. However, it can be said that both of the air flow passage and the outside air introduction passage have not only air circulation but also light emission.

The inventors of the present invention pay attention to this point, and by utilizing the air flow path and the outside air introduction path provided from the viewpoint of heat dissipation and air permeability as the decorative light radiation path, the decorative effect according to the present invention is achieved. Has succeeded in rationally raising.

Specifically, in the solution 6 described above, the gaming machine of the present invention includes a light-transmitting decorative body that decorates the display screen or the periphery of the production operation body, one end opening in the drum-shaped main body of the production operation body, and the display unit. And a light radiation path for emitting decorative light from the light source to emit light from the interior of the drum-shaped main body. In this case, since the light source originally used for lighting display of the effect operating body can be used for the purpose of causing other decorative bodies to emit light, the decorative effect can be enhanced while effectively using the light source.

The gaming machine of the present invention can improve heat dissipation from various heat source units, devices, and equipment, and can reliably prevent these from being adversely affected by heat.

In addition, the gaming machine of the present invention can prevent heat from being partially accumulated in the unit, and can take measures against heat that are effective as a whole.

For this reason, when the fan device 21 is operated, an upward air flow is generated in the radiating air layer. Accordingly, for example, below the radiating air layer (on both sides of the retaining piece 20b, the connecting frame 22 and the display unit 16). The outside air is introduced from a gap portion between the radiating air layer and the inside of the radiating air layer.

(3-8. Ventilation Holes) Further, the substrate box of the control unit 20 is appropriately formed with ventilation holes 20f on the upper end surface, the lower end surface and the back surface thereof. Since a part of the blade rotation area of the fan device 21 is arranged so as to overlap the vent hole 20f, the inside of the control unit 20 can be ventilated by the blowing force.

As described above, in the present embodiment, since the radiating air layer is formed between the back surface of the display unit 16 and the front surface of the control unit 20, heat generated from each unit can be released to the radiating air layer.

Further, since the inside of the radiating air layer is ventilated by the fan device 21, the heat released from each unit is not trapped or accumulated in the radiating air layer, and the heat radiating efficiency can be greatly improved. . Furthermore, since the inside of the control unit 20 is ventilated by the fan device 21, heat is not accumulated or accumulated in the board box. Therefore, it is possible to prevent the display unit 16 and the control unit 20 from being adversely affected by heat and to realize stable operation of each unit.

The above is a description of the heat radiation air layer formed between the display unit 16 and the control unit 20, but in this embodiment, the heat radiation efficiency is further improved by the air flow path and the outside air introduction path communicating with the heat radiation air layer. This is also realized and will be described below with specific examples.

(3-9. Drum Unit) FIG. 6 shows the drum unit 18 in an exploded state. Here, the drum unit 18 positioned on the right side as viewed from the front is taken up, but the left drum unit 18 has a similar or symmetrical configuration.

(3-9-1. Producing action body (movable body)) Each drum unit 18 has three drums 18a which are movable bodies. These drums 18 a are rotatable around a horizontal axis, and are arranged in three upper and lower stages in the drum unit 18. Each drum 18a has a symbol display band (no reference symbol) affixed to the outer peripheral surface thereof, and a decorative symbol designed with the numeral “7” is attached to the symbol display band, for example. Note that a plurality (for example, five) of decorative symbols are arranged in the circumferential direction of the drum 18a.

The drum unit 18 also includes three stepping motors 18b corresponding to the three drums 18a. The side surface (right side surface in this example) of the drum unit 18 is covered with the motor base 18c, and the three stepping motors 18b are arranged in three upper and lower stages so as to be directed to the outer surface of the motor base 18c.

The drum unit 18 can realize a display operation by a movable body using the drum 18a and the stepping motor 18b, but the drum unit 18 further includes a device for performing a light emitting decoration.

(3-9-2. LED board) The light emitting decoration by the drum unit 18 is for emitting transmitted light from the inside of each drum 18a to light up and display the decorative design. For this reason, the drum unit 18 includes a light source and An LED substrate 18d is built in. Three sets of LED boards 18d are prepared corresponding to the respective drums 18a, and these are accommodated in an integral lamp housing 18e, respectively. The lamp housing 18e is covered with a casing 18f at the top, bottom, and rear, and the casing 18f is also formed integrally with the lamp housing 18e.

Further, a light diffusion plate 18g is attached to the front surface of each lamp housing 18e, and the light diffusion plate 18g is curved so as to protrude forward. The front surfaces of the three lamp housings 18e are further covered with a clear cover 18h, and the decorative design of each drum 18a is visible through the clear cover 18h. The clear cover 18h is fixed to the casing 18f at the top and bottom.

(3-9-3. Structure of Drum Unit) FIG. 7 shows a longitudinal section of the drum unit 18. As described above, the lamp housing 18e is arranged in three upper and lower stages corresponding to each drum 18a, and a gap for preventing interference with the drum 18a is secured between them. Therefore, the three drums 18a are combined so as to cover the outer sides of the corresponding lamp housings 18e, and can freely rotate in this state.

The individual lamp housings 18e are formed in a size that fits inside the drum 18a. As is apparent from the cross-sectional shape of FIG. 7, the lamp housing 18e has a tapered shape (C-shape) that expands forward, and holds the LED substrate 18d in a vertical posture at a position behind it.

The light diffusing plate 18g is disposed along the inner peripheral surface of the drum 18a, while the clear cover 18h is formed in a wave shape along the outer peripheral surface of each drum 18a. The light emitted from the LED elements on the LED substrate 18d is radiated forward from the lamp housing 18e and is diffused widely by the light diffusion plate 18g. As a result, the surface of the light diffusing plate 18g emits light substantially uniformly, so that the decorative design of the drum 18a is lit and displayed as a whole as viewed from the player.

The drum unit 18 has a substrate box 18i, which is attached to the back side of the casing 18f. A relay board is built in the board box 18i, and devices for relaying control signals for the stepping motor 18b, the LED board 18d, and the like are mounted on the relay board.

(3-10. Air Flow Path) Next, FIG. 8 shows a cross section of the drum unit 18 together with the display unit 16 and the control unit 20 described above. In FIG. 8, only the left drum unit 18 is shown, but the right drum unit 18 can be considered symmetrically.

As already described, the drum units 18 are respectively disposed on both sides of the display unit 16, and at this time, a certain interval is secured between both side surfaces of the display unit 16 and each drum unit 18. In the present embodiment, air flow passages can be formed on both sides of the display unit 16 by using this interval. Specifically, when the radiating air layer is ventilated by the fan device 21, an air flow is formed in a direction that wraps around from the both side surfaces of the display unit 16 to the back surface. Therefore, in this embodiment, the space on both sides of the display unit 16 is also ventilated together with the heat radiating air layer, so that the heat released from the side surface of the display unit 16 does not stay and the heat radiation efficiency is greatly improved. .

(3-11. Outside Air Introducing Path) In the drum unit 18, an outside air introducing path for introducing outside air into the air flow path and the radiating air layer is formed. Specifically, as shown in FIG. 8, each drum 18 a has a main body (drum-shaped main body) at one end (a side end facing the display unit 16) that opens widely, and a hub portion 19 at the other end. Is formed. The hub portion 19 reinforces the other end of the drum 18a in the radial direction and is connected to the output shaft of the stepping motor 18b at the center thereof.

Further, a vent hole 19a is formed between the peripheral edge and the center of the hub portion 19, and air permeability into the drum 18a is secured by the vent hole 19a. The motor base 18c is also appropriately formed with an opening 19b, and the opening 19b ensures air permeability from the outside to the inside of the casing 18f.

When ventilation of the radiating air layer is performed by the fan device 21 as described above, outside air is introduced into the casing 18f from the opening 19b of the motor base 18c as indicated by arrows in FIG. The air flows from the inside of the casing 18f to the inside of the drum 18a through the vent hole 19a of the hub portion 19 and passes through the inside of the lamp housing 18e (the space between the both side surfaces of the display unit 16 and the drum unit 18). Space).

At this time, since the air flow passing through the front and rear of the LED board 18d is formed inside the lamp housing 18e, the periphery of the LED board 18d is efficiently ventilated. In addition, an opening 19c is formed on the rear surface of the casing 18f at the rear position of each lamp housing 18e, and good air permeability is ensured between the board box 18i and the casing 18f through the opening 19c. .

(3-12. Summary of Ventilation / Heat Dissipation) As described above, in the present embodiment, outside air is introduced into the drum unit 18 through the outside air introduction path, and this is circulated inside the drum 18a and the lamp housing 18e, and one end of the drum 18a. It can be guided to the side of the display unit 16 from the opening. The introduced outside air circulates from the side of the display unit 16 to the back side, and merges with the air flow in the heat radiating air layer.

Therefore, in the present embodiment, heat generated from the stepping motor 18b and the LED board 18d is not trapped or accumulated in the casing 18f or the lamp housing 18e, and the heat dissipation efficiency can be greatly improved. For this reason, the malfunction and damage by the thermal effect of an LED element are prevented especially and the production | presentation operation | movement by light emission decoration can be performed stably over a long period of time.

Further, since the inner space of the three drums 18a is used as a ventilation duct, an air flow toward the side surface of the display unit 16 can be formed, and the heat dissipation efficiency of the display unit 16 is further improved by this air flow. be able to.

(4. Decorative Action) Next, the improvement of the decorative action according to the present embodiment will be described. First, FIG. 9 shows the decorative body 14b and the drum unit 18 of the center accessory device 14 in the same cross section as FIG. Although the left drum unit 18 and the decorative body 14b are shown in FIG. 9, the right one can be considered symmetrically. In FIG. 9 and subsequent figures, reference numerals may be given only to parts related to the description, and reference numerals may be omitted for other parts.

In the center accessory device 14, the decorative body 14b which becomes the neck of the dragon is arranged along both side edges of the display screen 16a. The interior of the decorative body 14b is formed as a warp passage having a U-shaped cross section for guiding a game ball. A ball guide plate 24 is disposed behind the decorative body 14b so as to close the warp passage. The ball guide plate 24 extends in the vertical direction together with the decorative body 14b. When the game ball actually flows down in the warp passage, the game ball is guided along the inner surface of the ball guide plate 24 and the inner surface of the decorative body 14b.

Further, an LED board 26 is arranged behind the ball guide plate 24 with a certain interval, and the LED board 26 extends vertically along the rear side of the decorative body 14 b and the ball guide plate 24. A large number of LED elements are arranged on the LED substrate 26 at intervals in the vertical direction, and these LED elements can emit light from behind the ball guide plate 24 toward the front.

The spherical guide plate 24 and the decorative body 14b are both made of a light-transmitting resin molded member, and the light emitted from the LED elements is transmitted through the spherical guide plate 24 and the decorative body 14b and viewed from the front side. Since the spherical guide plate 24 and the decorative body 14b are respectively provided with uneven portions, designs, cuts, etc., the light from the LED elements is diffused in a complicated manner by the spherical guide plate 24 and the decorative body 14b.

(4-1. Light Radiation Path) Apart from the LED board 26 described above, in the present embodiment, the decorative body 14b can also emit light by using the backlight (LED board 18d) of the drum unit 18 as a light source.

Specifically, as already described, one end of each drum 18a is opened widely, and the lamp housing 18e is also opened toward the side surface of the display unit 16 like the drum 18a. When the LED element is caused to emit light, the decorative light is emitted not only in front but also in the lateral direction.

For example, as indicated by an arrow in FIG. 9, the decorative light emitted from the lamp housing 18 e in the lateral direction passes obliquely forward through the space between one end opening of each drum 18 a and the side surface of the display unit 16. Is also emitted. In the present embodiment, the main body of the drum 18a projects forward of the display screen 16a on the front side of the drum unit 18, and a certain gap is secured between the one end opening of the main body of the drum 18a and the LED board 26. Therefore, the decorative light is actually emitted obliquely forward from the inside of the lamp housing 18e through this gap (light emission path). The decorative light emitted from the lamp housing 18e is visible from the front side through the spherical guide plate 24 and the decorative body 14b, and is similarly diffused by the spherical guide plate 24 and the decorative body 14b.

(4-2. Relationship with Center Character Device) FIG. 10 shows a state in which the decorative body 14b on the left side is separated in the center character device 14. Further, in the drawing, the illustration of the ball guide plate 24 in the back of the left decorative body 14b is omitted.

As shown in FIG. 10, when the drum unit 18 and the display unit 16 are combined with the center accessory device 14, the display screen 16 a is located in a region partitioned in the center of the center accessory device 14, and both sides thereof are displayed. Thus, the drums 18a are respectively located in the small areas subdivided into three stages. At this time, when the ball guide plate 24 and the decorative body 14b are removed from the center accessory device 14, a part of the drum unit 18 can be viewed from the front side through a gap that is formed after the ball guide plate 24 and the decorative body 14b are removed. It has become.

As described above, in the positional relationship between the center accessory device 14 and the drum unit 18, the decorative light radiated from the drum 18a and the lamp housing 18e passes through the ball guide plate 24 and the decorative body 14b and is favorably viewed from the front side. It is understood that the structure is visible.

(4-3. Light emission control of LED board) FIG. 11 shows the spherical guide plate 24 and the decorative body 14b in a vertical section. As described above, it is understood that the decorative body 14b is entirely emitted from the top to the bottom by radiating the decoration light obliquely forward from the three drums 18a of the upper, middle, and lower sides.

The decorative light emitted from the drum 18a is originally intended to light up and display the decorative pattern of the drum 18a, so that the light emission timing is controlled exclusively in accordance with the operation of the drum unit 18. Accordingly, when the drum 18a is not decorated for light emission in the control of the drum unit 18, the decoration light is not emitted to the decorative body 14b.

On the other hand, the LED board 26 is a device for positively emitting the decorative bodies 14a and 14b, and the light emission operation by the LED board 26 is controlled in conjunction with entering the warp path. Specifically, as shown in FIG. 11, a ball entry switch 28 is arranged at an upper position of the warp passage. When a game ball jumps into the warp passage, the ball entry switch 28 detects this. The light emission control of the LED substrate 26 is performed.

At this time, all the LED elements on the LED board 26 are not lit at the same time. For example, the lighting timing is controlled so that the lighting position is shifted sequentially from top to bottom. It is recognized as if the part (decorative body 14a) emits light first, and then the decorative light flows down through the dragon's neck (decorative body 14b). In addition, the flow speed of the game ball is reduced in the warp passage, and the transition operation of the lighting position of the LED element is controlled so as to be synchronized with the flow operation.

As described above, in the present embodiment, in the center accessory device 14, the decorative body 14b can emit light using at least two systems of light sources (LED substrates 18d and 26). In this case, the decorative body 14b can be caused to emit light in conjunction with the lighting display of the drum unit 18, and the decorative body 14b can be caused to emit light in conjunction with the ball entry operation to the ball entrance 14c. The range of production variations can be expanded.

The operation of the drum unit 18 and the light emission operation of the LED board 26 are controlled by the sub-control board of the pachinko machine, and the control configuration will be described below.

(4-4. Configuration of Control System) FIG. 12 schematically shows the configuration of the control system in the pachinko machine. On the back side of the game board 1, a sub control board 32 is disposed together with the main control board 30. Each of the control unit 20 and the drum unit 18 receives a control signal from the sub-control board 32 and performs each process.

The sub-control board 32 is connected to the LED board 26 and the ball entry switch 28 and to the speaker device 34. The speaker device 34 is for outputting a sound effect and sound on the production, and its operation is controlled in accordance with the production operation by the display unit 16 and the drum unit 18.

(4-5. Contents of Control Processing) A large number of LED elements are mounted on the LED board 26, and the control system of these LED elements is three blocks (upper LED 26a, middle LED 26b, lower LED 26c). Each block includes a plurality of LEDs, and the upper, middle, and lower LEDs 26a to 26c are controlled to emit light collectively for each block.

(4-5-1. Basic Pattern) Specifically, when a game ball jumps into the ball entrance 14c of the center accessory device 14 during the game, the ball entry switch 28 detects this, and the detection signal is sub-controlled. Input to the substrate 32. When this detection signal is received, the CPU of the sub control board 32 (hereinafter referred to as “sub CPU”) starts a predetermined timer counter. At this time, the sub CPU can also operate the speaker device 34 to perform an effect operation using a sound effect (so-called direct hit sound) when entering the ball.

Next, the sub CPU counts the elapsed time with this timer counter, and the time required for the game ball to reach the dragon's head (decorative body 14a) in the warp passage after entering the ball entrance 14c (for example, 0.1). First, the upper LED 26a is caused to emit light (ON) in units of blocks.

Subsequently, when a predetermined time (for example, 0.5 seconds) elapses, the sub CPU stops (turns off) light emission from the upper LED 26a, and then causes the middle LED 26b to emit light in block units. When a predetermined time further elapses, the sub CPU stops the light emission of the middle LED 26b, and this time the lower LED 26c is caused to emit light in block units. When a predetermined time elapses thereafter, the sub CPU stops light emission of the lower LED 26c and turns off all the LEDs.

In this way, the sub CPU performs light emission control for each of the three blocks, and when the game ball jumps into the ball entrance 14c, the decoration bodies 14a and 14b simulating the head and neck of the dragon are directed from top to bottom. This makes it possible to obtain a visual effect as if decorative light is flowing down along with the game ball.

Since the center accessory device 14 is provided with two left and right decorative bodies 14a and 14b, the above-described light emission control is performed separately for the left and right LED boards 26. Therefore, for example, when a game ball jumps into the right ball inlet 14c during the game, the right decorative bodies 14a and 14b emit light correspondingly, and conversely, when a game ball jumps into the left ball inlet 14c, Correspondingly, the left decorative bodies 14a and 14b emit light. Even when the game balls jump into the left and right ball inlets 14c, if the timing of the game balls jumps in on the left and right, the light emission control of the LED board 26 is performed separately in accordance with the respective ball entry timings.

(4-5-2. Application Pattern) The basic pattern of the light emission control by the sub CPU has been described above. In addition, in this embodiment, a multicolor (or full color) LED element is used for the LED substrate 26. In the light emission control, the light emission mode (emission color, luminance, light emission timing, etc.) of the LED element can be varied according to the gaming state.

For example, during the special symbol variation display by the display unit 16 or the like, the sub CPU determines the jackpot reliability based on the variation pattern signal transmitted from the main control board 30, and the LED element according to the reliability at this time. It is possible to perform control to vary the emission color. In this case, when the CPU determines that the reliability of the jackpot is high, the CPU performs light emission control using colors with high visual appeal (for example, red, white, blue, etc.). On the other hand, when the sub CPU determines that the reliability is not so high, the sub CPU can perform light emission control using a color (for example, green or yellow) whose visual appeal is not so high.

When the sub CPU performs the above light emission control, the effect of the decorations 14a and 14b can be further enhanced, and the player can play a game with a strong expectation for the big hit.

In addition to the above, if the sub CPU determines that the reliability of the big hit is high during the special symbol variation display, the LED element emits light with higher brightness than usual, and the upper, middle and lower LEDs 26a to 26c blink. You can also make it emit light. Or, in the case of high reliability, by making the transition of the light emission position from the upper LED 26a to the lower LED 26c faster than usual, the effect of repeating the flow of decorative light in the decorative bodies 14a, 14b is performed two or more times. You can also.

In addition, the light emission mode of the LED element is different between when the special symbol is changing and when it is not changing, or is different between the big hit game and the normal game, and further, the privilege state after the big hit (so-called Various application patterns can be mentioned for effects by the light emission control of the LED substrate 26, such as providing a light emission mode peculiar to a certain change, time shortening, etc.

Further, the sub CPU can further enhance the interest of the player by adding the effect by the sound effect / BGM in conjunction with the light emission control of the LED board 26 in conjunction with the speaker device 34.

(4-6. Structure of Warp Path) As described above, in the warp path, the falling speed of the game ball is reduced in accordance with the light emission control of the LED board 26 by the sub CPU, and finally the lower LED 26c is turned off. Then, the game ball is released from the ball discharge port 14d almost at the same timing. For this reason, the warp passage not only guides the game ball but also has a structure capable of appropriately preventing the falling movement.

(4-6-1. External Shape of Decorative Body) FIG. 13 shows a state when the left and right decorative bodies 14 b are removed from the center accessory device 14. In actual structure, the decorative body 14b is composed of parts in which the dragon's neck and lower jaw are integrated, and the other decorative body 14a is integrally formed with the dragon's head and upper jaw. .

As described above, a design imitating the dragon's neck is applied to the outer surface of the decorative body 14b that is symmetrical on the left and right. Among these, the half located in the center side when viewed from the front of each decorative body 14b is formed such that its outer shape undulates up and down imitating a bellows shape. On the other hand, the portion located almost in front of the bellows portion is formed so that the outer shape thereof is shaped like a scale on the flank of the dragon. Further, the portion located on the left and right sides adjacent to the scale-like portion has a triangular wave shape that imitates the back of the dragon.

(4-6-2. Shape of Ball Guide Plate) FIG. 13 shows the ball guide plate 24 attached to the center accessory device 14. When viewed in the vertical direction, the guide surface (front surface) of the ball guide plate 24 is formed in a curved shape in accordance with the curved shape of the warp passage, and a number of obstacle protrusions are formed in the vertical direction on this guide surface. 24a is formed. These obstacle protrusions 24a are arranged at an appropriate interval and protrude from the guide surface toward the front side, that is, into the warp passage. Note that FIG. 10 can be referred to as appropriate for the cross-sectional shape of the ball guide plate 24 and the outer shape of the obstacle protrusion 24a.

(4-6-3. Inner surface shape of decorative body) Next, Fig. 14 specifically shows the inner surface shapes of the left and right decorative bodies 14b. As described above, the warp passage is composed of a vertically long space surrounded by the inner surface of the decorative body 14 b and the ball guide plate 24. For this reason, by appropriately forming the obstacle protrusions 13 and 15 on the inner surface of the decorative body 14b, an appropriate obstacle is given to the falling motion of the game ball in the warp passage, and the dropping speed is suitably reduced. Is possible.

The falling speed of the game ball assumed here is synchronized with the switching timing of the upper, middle, and lower LEDs 26a to 26c by the sub CPU. That is, in the light emission control of the LED board 26, the falling speed in the warp passage is reduced in accordance with the timing at which the light emission position shifts from the upper block to the middle and lower stages. In this embodiment, the curved shape of the warp passage, the size of the obstacle protrusions 24a, 13, 15 and the like, the arrangement interval, and the like are appropriately set so as to obtain the above-described deceleration effect.

(4-6-4. Decorative Problems) Here, from the viewpoint of the player, the above-mentioned ball guide plate 24 is in a position hidden behind the decorative body 14b, so that the presence of the obstacle protrusion 24a is particularly visually recognized. Is never recognized. However, since the outer shape of the decorative body 14b is directly visible to the player and has light transparency, the presence of the obstacle protrusions 13 and 15 is present even though it is formed inside. It is easier to visually recognize from the outside. For this reason, if the obstacle protrusions 13 and 15 are formed considering only the deceleration effect in the warp passage, the balance with the design of the outer surface is lost when the presence of the obstacle protrusions 13 and 15 is visually recognized from the outside. , There is a risk that precious decorativeness is impaired.

Therefore, in the embodiment of the present invention, it is an object to obtain a sufficient deceleration effect without impairing the decorative properties of the decorative body 14b and the like.

(4-6-5. Solution) In the embodiment of the present invention, it should be noted that the shapes of the obstacle protrusions 13 and 15 formed on the inner surface of the decorative body 14b are all on the outer surface of the decorative body 14b. It is a point that is given unity and relevance to the design.

Specifically, first, the obstacle protrusion 13 is formed at a position corresponding to a portion simulating a dragon bellows shape on the outer surface of the decorative body 14b, and each of the obstacle protrusions 13 is provided on the outer surface. Each node is formed so as to protrude to the inner surface side.

The other obstruction projection 15 is formed at a position corresponding to a portion imitating the back of the dragon on the outer surface of the decorative body 14b, and the obstruction projection 15 is substantially the same as the portion protruding in a triangular shape on the outer surface. It has the outer shape.

For this reason, from the viewpoint of the player, the presence of the obstacle protrusions 13 and 15 on the inner surface of the decorative body 14b is difficult to visually recognize, or even if the presence is recognized, the outer surface design depends on the respective shapes. A sense of unity is recalled. Thereby, the obstacle protrusions 13 and 15 can sufficiently exhibit the function of decelerating the game ball in the warp passage, and can fully utilize the design and decorative functions of the decorative body 14b.

(5. Reference to Other Embodiments) The above is the description of one embodiment, but the embodiment of the present invention is not limited thereto. In the following, other embodiments will be described with some examples.
