BACKGROUND OF THE INVENTION
  The present inventionA gaming machine equipped with an output device capable of outputting various sound effects while a middle frame having a game board disposed thereon is assembled to an opening front surface of an outer frame formed in a rectangular frame shapeAbout.
[0002]
[Prior art]
For example, a gaming machine such as a pachinko machine or an arrangement ball machine has various symbol display devices that can variably display identifiable symbols such as numbers and characters at required positions in the gaming area set on the gaming board. The symbol display device is configured to perform symbol variation and various effects (reach effect, jackpot effect, etc.) corresponding to the gaming state. In addition, an output device capable of outputting various sound effects is disposed at a predetermined position of the gaming machine, and the player can play an entertaining game by outputting sound effects in accordance with the effects on the symbol display device. To get to do.
[0003]
The output device is disposed on the back side (the back side of the gaming machine) corresponding to the mounting hole formed in the mounting member such as a lower ball tray, for example, and the output portion facing the front side communicates with the mounting hole. . For the purpose of protecting the output portion, a cover body is disposed between the attachment member and the output device. The cover body is fixed by being screwed to the attachment member at a plurality of positions from the rear with the screws positioned in a state of being aligned between the attachment hole of the attachment member and the output portion of the output device. .
[0004]
[Problems to be solved by the invention]
In the gaming machine, after the cover body is screwed to the mounting member with a screw, the output device is screwed to the mounting member with the screw. That is, since a screw for the cover body and a screw for the output device are required, there is a problem that the number of parts is increased and the cost is increased. In addition, since screws are screwed into a plurality of locations in order to securely attach the cover body, the number of work steps is large and the work is very troublesome. Furthermore, there is a possibility that a gap is formed between the attachment member and the cover body at a position where the tightening of the screw is weak or away from the screw. When a gap is generated between the mounting member and the cover body, sound output from the front surface of the output unit in the output device leaks from the gap and interferes with sound output from the rear surface of the output unit, Since the sound output from the rear surface of the output unit leaks from the gap and interferes with the sound output from the front surface, it becomes difficult to output a clear sound and the fun of the game is impaired. In this case, since the cancellation of the sound particularly in the low frequency range becomes strong, there is a problem that the power of the game and the sense of reality are poor.
[0005]
Further, when the output device is screwed to the mounting member with a screw, there may be a gap between the cover body and the portion other than the screwing position. This causes problems such as the sound output to the player canceling out and the sound heard by the player becoming unclear.
[0006]

[Action]
  The present inventionFront plate of the lower frame member that forms the lower side of the outer frameAnd a frame-like frame surrounding the output portion of the output device,First of the front plateWith the protective cover body of the output part facing the opening part interposed, the sub frame is brought into contact with the frame of the output device from the back side, and the sub frame isFront plateBy attaching to the back side of theFirstThe output device is mounted and fixed in a state facing the opening. In addition, the subframeFront plateBy attaching to the back side ofThe frame of the output device is in close contact with the plate-like portion of the subframe, the entire circumference of the contact portion of the protective cover body is in close contact with the frame of the output device, and the contact portion of the protective cover body and The entire circumference of each partition is closely attached to the back of the front plate. Thus, the protective cover body of the output unit can be fixed without using screws or the like, and the number of parts can be reduced to reduce the cost. Further, since the screw tightening work is reduced, the attaching work can be easily performed and the working time can be shortened. Furthermore,The frame of the output device is brought into close contact with the plate-like portion of the subframe, the entire circumference of the contact portion of the protective cover body is brought into close contact with the frame of the output device, and the contact portion of the protective cover body and By sticking the entire circumference of each partition against the back of the front plateIt is possible to suppress the formation of a gap between the members. As a result, the sound output to the front (rear) of the output unit does not pass through the back (front) through a gap, and canceling out due to sound interference is prevented, so there is power and presence. You can play games.
[0014]
In addition, a housing case for housing the output device is disposed on the rear side of the output device, and an airtight housing portion is defined by the housing case and the front plate, so that the front and rear of the output device can be further improved. Interference of the output sound can be suppressed, and a clear sound can be output. In addition, since the bass reflex duct that connects the inside and the outside of the housing portion is provided, the low frequency range of the sound output from the output device can be enhanced, so that it is possible to output a realistic sound and powerful sound.
[0015]
In addition, a plurality of protrusions are formed on the back side of the front plate and at a required portion surrounding the opening, and a plurality of protrusions are allowed to be inserted into a portion of the subframe that is in contact with the output device frame. If the bottomed holes are correspondingly recessed and a protrusion is inserted into the bottomed hole, the subframe can be positioned at a predetermined position and temporarily fixed. That is, since the output device and the protective cover body can be easily positioned and temporarily fixed, the mounting operation can be made efficient and the working time can be shortened. In addition, since the through-hole penetrating the bottom of the bottomed hole is formed, when the subframe is temporarily fixed to the protrusion, a screw is inserted into the through-hole and screwed to the protrusion. The output device and the protective cover body can be easily fixed to the back side of the front plate.
[0016]
Furthermore, when the subframe is temporarily fixed, a slight gap is formed between the bottom of the bottomed hole and the top surface of the protrusion, thereby screwing the screw into the protrusion. Further, since the gap is crushed and retightening is allowed, a uniform pressing force can be applied over the entire circumference of the frame of the output device via the subframe. By forming a slight gap between the bottom of the bottomed hole and the top surface of the protrusion, and tightening it, the protective cover body is firmly attached to the frame and the back side of the front plate over the entire circumference. It is closely attached to. That is, the protective cover body can be prevented from falling off from the front plate, and the front and rear of the output unit can be more reliably separated from each other, and interference of sound output from the front and rear of the output device can be suppressed. In addition, since the output device is also firmly fixed, it is possible to reduce so-called chatter noise caused by resonance.

Therefore, when the members 23 and 24 are fixed, the gap S is crushed to allow additional tightening. In this way, by tightening, the mounting base 20a of the output device 20 moves forward via the subframe 24, and a uniform pressing force directed forward is applied over the entire circumference of the mounting base 20a. Can do. Thereby, the mounting base 20a is in close contact with the entire circumference of the first flange portion 35b of the second cover member 33. Further, the first flange portion 35b of the second cover member 33 exerts a uniform pressing force directed forward over the entire circumference of the second flange portion 37b in the mounting frame 37. The entire portion 37b is in close contact with the back side of the front plate 73.
[0061]
That is, the protective cover body 30 is firmly sandwiched and fixed between the back side of the front plate 73 and the mounting base 20a. For this reason, the protective cover body 30 can be easily removed from the opening portion 22 of the front plate 73 even if the pachinko machine P is vibrated during loading / unloading or the player pushes the protective cover body 30. The front side of the output unit 21 can be reliably protected. In addition, since the output device 20 is firmly fixed, generation of so-called chatter sound caused by resonance can be effectively suppressed, and the sound quality can be further improved.
[0062]
Here, generally, before and after the output device 20, for example, when a diaphragm (not shown) of the output device 20 moves forward, the air on the front surface is pushed and becomes “tight”, The reverse action is performed with the output device 20 as a boundary so that the rear surface is “sparse” with thin air. That is, it is known that sound of opposite phase is output from the front and rear of the output device 20, and if the sound of opposite phase output from the front and rear interferes, the sounds cancel each other and the sound becomes unclear. (Especially, the effect is significant for the low frequency range). However, in the output device mounting structure according to the embodiment, the back base of the output device 20 and the front plate 73 is provided over the entire circumference of the protective cover body 30 by retightening and fixing the subframe 24. It is closely attached. That is, the gap generated between the protective cover body 30 (first flange portion 35b) and the mounting base 20a and between the protective cover body 30 (second flange portion 37b) and the back side of the front plate 73 is reduced. Can do. For this reason, since the sound output from the front surface of the output unit 21 does not easily reach the rear surface side of the output unit 21, cancellation due to interference with the sound output from the rear surface is prevented. Sound can be transmitted to the player, and the interest of the game is increased. In addition, since cancellation of sounds in the low frequency range is prevented, it is possible to perform a game effect with a powerful and realistic feeling.
[0063]
Further, when the inner bottom surface 25a of the fixing recess 25 is in contact with the rear end portion of the boss portion 23 by further tightening, the lower frame member extends over the entire circumference of the front end edge of the partition wall 24c in the subframe 24. It adheres to the back side of 41. As described above, the partition wall 24c is in close contact with the back side of the lower frame member 41 outside the protective cover body 30 that is in close contact with the back side of the mounting base 20a and the front plate 73. Interference between the sound output from the front surface and the sound output from the rear surface can be prevented. Further, since the backlash of the sub-frame 24 is reduced, so-called chatter noise generated by resonance can be effectively suppressed, and the sound quality can be further improved.
[0064]
In the embodiment, the gap S generated between the rear end portion of the boss portion 23 and the inner bottom surface 25a of the fixing recess 25 is set to be in the range of 0.5 mm to 1.5 mm. It is not restricted to this, It can be set as a required space | interval.
[0065]
(Operation of protective cover member)
Further, various sound effects output from the output unit 21 of the output device 20 are the openings of the protective cover body 30 including the first cover member 31 and the second cover member 33 disposed on the front side of the output unit 21. It passes through 31a, 33a and is transmitted to the outside (players, etc.). Thus, since the front side of the output unit 21 of the output device 20 is protected by the protective cover body 30 including the first and second cover members 31 and 33, the second side disposed on the front side. It is possible to restrict the foreign matter inserted into the opening 33a of the cover member 33 with the first cover member 31 disposed on the rear side.
[0066]
That is, the openings 31a and 33a of the first and second cover members 31 and 33 are formed in a slit shape and a substantially circular shape, respectively, and the opening width Z of the opening 31a of the first cover member 31 is set to the second cover member. Since the opening 33a is set to be smaller than the diameter of the opening 33a, even if foreign matter enters the opening 33a of the second cover member 33 on the front side, the opening 31a of the first cover member 31 can be easily passed through. The output unit 21 of the output device 20 can be prevented from being damaged. For example, even when the opening 31a of the first cover member 31 faces behind the opening 33a of the second cover member 33, the opening width Z of the opening 31a in the first cover member 33 is Since the diameter of the opening 33a in the second cover member 33 is set smaller than the diameter of the opening 33a, as shown in FIG. 10 (b), a round bar-like foreign substance U is inserted into the opening 33a of the second cover member 33. In addition, the first cover member 31 can be prevented from entering the slit-shaped opening 31a. If the openings 31a and 33a do not overlap in the front-rear direction, the foreign matter U that has been passed through the opening 33a of the second cover member 33 is allowed to enter the output portion 21 side. The restricting portion 31b and the connecting portion 31c are blocked.
[0067]
In addition, the first cover member 31 disposed on the output unit 21 side of the output device 20 is connected to a plurality of restricting portions 31b which are separated from each other at a required interval in the front-rear direction and whose outer dimensions become smaller toward the rear side. It arrange | positions in the outer frame 32 via the member 31c, and the opening part 31a is formed between each control part 31b. That is, as shown in FIG. 9, even if the opening width Z at which each opening 31a opened in the slit shape opens in the forward direction is narrow so that foreign matter does not enter the opening 31a, the opening Since the opening width Y opening in the oblique direction of 33a is sufficiently wide and a large effective opening area in the opening 31a can be ensured, the passage of the sound effect is hardly hindered and the sound effect is given to the player. Can communicate clearly. Further, each regulating portion 31b of the first cover member 31 is located in the vicinity of the output portion 21 that is formed in a concave shape toward the substantially central portion thereof, so that the first cover member 31 is connected to the output device. Since the depth dimension in the state attached to 20 becomes compact, the output part 21 can be arrange | positioned close to a player, and it is possible to transmit a clear sound effect.
[0068]
As described above, since the first cover member 31, the second cover member 33, and the attachment frame 37 are detachably assembled, the protective cover body 30 is handled in a state where it is assembled as a single member. It becomes possible. Thereby, since the number of handling parts at the time of attaching the output device 20 can be reduced, assembly work can be simplified and work efficiency can be improved. In addition, since the protective cover body 30 is formed of separate members, when each member is damaged, only the damaged member can be replaced, and costs, waste, and the like can be reduced. In addition, a change can also be given to designability by employ | adopting the attachment frame 37 of a different shape and design for every game machine.
[0069]
(Enclosure structure, operation of bass reflex duct)
Since the output device 20 is arranged on the rear side of the front plate 73 of the lower frame member 41 in the outer frame A of the pachinko machine P having a relatively large space, the large-size and high-performance output device 20 is provided. Can be adopted. As described above, the output device 20 is disposed at the lower position of the pachinko machine P, and the bass reflex duct 105 is opened at the substantially longitudinal lower position of the pachinko machine P. Thus, various effects are provided near the abdomen of the player. The sound is output and the player can feel a powerful sound and can play a game with a sense of reality.
[0070]
Further, as described above, when sounds output from before and after the output unit 21 interfere with each other, they cancel each other out and the sound becomes unclear. However, in this embodiment, the housing case 103 covers the rear of the output device 20, and the housing case 103 and the lower frame member 41 are brought into close contact with each other to define the housing portion 104 of the enclosure structure. A rear portion of the output device 20 is accommodated in the portion 104. For this reason, the interference of the sound output from before and after the output device 20 is prevented, so that a clear sound effect can be output, and the player can play a more interesting game. In addition, it is possible to change the limit (limit frequency) of the low frequency range that can be output clearly by changing the volume of the accommodating portion 104 (in general, the limit frequency is lowered by lowering the volume and lower). It is possible to output sound effects in the range). In addition, a rubber packing is disposed between the housing case 104 and the front plate 73 so as to ensure the airtightness of the housing portion 104, so that the sound effect output from the output device 20 can be reduced. Sound leakage can be prevented.
[0071]
Here, generally, when the output device 20 is accommodated in a box having a duct to output sound, the sound output from the rear surface of the output device 20 is so-called Hertzholm by the space in the box and the duct. It is known that the sound is resonated at a specific frequency (referred to as anti-resonance frequency) and radiates sound from the duct to the outside. Further, at the frequency higher than the anti-resonance frequency, the output device It is known that it has the same phase as that of the sound output from the front face of 20. That is, by providing the bass reflex duct 105 that allows the inside of the enclosure structure housing portion 104 to communicate with the outside, the bass region is enhanced by the Hertzholm resonance phenomenon between the enclosure structure housing portion 104 and the bass reflex duct 105, It can output sound effects with an emphasis on the low frequency range and excellent presence. The anti-resonance frequency enhanced by the bass reflex duct 105 can be determined by the volume of the housing portion 104 of the enclosure structure, the diameter and length of the bass reflex duct 105, etc., and the vicinity of the limit frequency is enhanced. It is preferable to set so as to be able to.
[0072]
(Operation of protective member)
A protective member 106 provided with a restricting piece 107 for restricting entry of foreign matter or the like into the housing portion 104 of the enclosure structure is disposed in an opening portion 105a where the bass reflex duct 105 opens to the outside. In addition, the player's fingers and foreign objects are prevented from being inserted into the housing portion 1104 and damaged. In addition, by arranging the plurality of flat plate members 107a vertically apart from each other at a predetermined interval, the sound passing through the through hole 106b of the protective member 106 is not hindered by the restricting portion 107, and the sound effect can be efficiently performed. Can be output. Further, each of the flat plate members 107a is inclined so as to be lowered at a required angle from the rear side toward the front side, so that, for example, even when water is zeroed, the flat plate member 107a allows the bass reflex duct 105 and the housing portion to be The entry into 104 can be restricted to prevent adhesion of dirt and the like. Furthermore, since it becomes difficult for the player to see the inside of the bass reflex duct 105, mischief such as insertion of fingers can be suppressed. Further, since the protective member 106 is detachably disposed by the fitting means of the locking hole 105b and the locking piece 106c, when the protective member 106 is damaged, only the protective member 106 can be replaced, and the replacement cost is reduced. And work time, waste, etc. can be reduced. In addition, a change can be given to designability by arrange | positioning the protection member 106 of a different shape and design for every game machine.
[0073]

[0085]
[Example of change]
In addition, although the Example demonstrated the case where the cover member which comprises the protective cover body which can protect the output part of an output device was set to two, it can also be comprised with three or more cover members. Also in this case, by forming the openings formed in the cover member in different shapes, it is possible to prevent the entry of foreign matter from the outside and prevent the output portion from being damaged. Here, when the protective cover body is constituted by three or more cover members, care must be taken so that the opening area does not become unnecessarily small. In addition, the shape of each cover member and its opening is not limited to that of the embodiment, and a triangular shape, a quadrangular shape, a star shape, or other shapes may be employed. For example, the outer frame of the cover member disposed on the rear side is formed in a substantially circular shape, and a plurality of openings having a required diameter are formed in a restriction portion formed in a concave shape toward the substantially central portion thereof, and arranged on the front side. It is also possible to form the cover member to be formed into a substantially circular shape having a size corresponding to the outer frame, and to form a rectangular opening in the plane portion. At this time, by setting the opening formed in the rear cover member to be smaller than the opening formed in the front cover member, foreign matter can be prevented from entering from the outside, Damage can be prevented.
[0086]
Locking pieces are formed at the upper and lower ends of the outer frame of the first cover member, but the position and number of the lock pieces can be set as required and correspond to the lock pieces on the second cover member. A locking hole may be formed at a position to be performed. Further, in the embodiment, the locking piece formed on the first cover member is fitted and fixed to the locking hole formed on the second cover member, but not limited to this, Various means known in the art such as adhesion using an adhesive can be used, but a means for detachably attaching is preferable.
[0087]
  And the storage caseFront plate of lower frame memberAlthough one output device is arranged on each of the left and right sides in the accommodating portion defined by the back side, the number and arrangement positions are not limited to this, and can be changed as appropriate. Furthermore, even if an output device for at least medium and high sounds is disposed as the output device in the housing portion of the enclosure structure, it is possible to output low-pitched and powerful sound effects. Further, although the output devices arranged on the left and right sides are accommodated in one accommodation case, each output device may be independently accommodated in the accommodation case. Moreover, although the output device is disposed at a lower position of the pachinko machine, the present invention is not limited to this, and the output device is disposed at a required position of the gaming machine, and the rear side is accommodated in the enclosure structure housing portion. If the inside and outside communicate with each other, it is possible to output a clear and powerful sound effect. Note that the bass reflex duct can be configured to be a labyrinth that is bent and extended, and the entire length of the duct can be lengthened to enable reproduction to a lower sound range. And if you use the so-called back load horn type that gradually expands the width of the bass reflex duct toward the output side (outside), you can play more strongly in the low range, so a crisp sound output is possible It becomes possible.
[0088]
Then, the engagement piece provided in the cover member is fitted and fixed to the engagement hole formed in the vicinity of the opening opened to the outside of the bass reflex duct. For example, various means known in the art such as screwing with an adhesive, bonding with an adhesive, and the like can be used, but a means for detachably attaching is preferable. In addition, although a plurality of flat plate-like restricting pieces are arranged on the cover member to constitute the restricting portion, other constitutions can be adopted as long as it is a constitution that can prevent entry of foreign matter or the like into the enclosure structure. In addition, in the case where a flat regulation piece is employed, the inclination angle can be changed as required.
[0089]
Moreover, although the case where the upper frame member and the left frame member are made of wood and the right frame member and the lower frame member are made of synthetic resin has been described, the material is not limited to that of the embodiment, but wood, synthetic resin Or a metal etc. can be used suitably. Further, the extended portion provided in the frame member is brought into surface contact with the inner surface of the frame member to be connected, but the extended portion is brought into surface contact with the outer surface of the frame member to be connected to reinforce the extended portion. A configuration in which the frame member is connected and fixed in a state where the frame member is sandwiched between the members may be employed. Furthermore, the number of bolts used at the connecting portion of each frame member is not limited to the number of examples, and can be appropriately selected according to the strength of use. Furthermore, in the embodiment, the fifth reinforcing member for connecting the lower frame member and the left frame member has been described as a case where the lower connecting member for assembling the front frame to the outer frame is also used. The left and right configurations of the members may be the same, and the third reinforcing member may be used instead of the lower connecting member.
[0090]
NaAlthough the output part of the output device arranged in the pachinko machine is protected by the protective cover body, the output is arranged in various game machines such as a slot machine machine and an arrange ball machine. It is possible to prevent damage to the output unit in the apparatus.

  As described above, according to the present invention.Game machineIsFront plate of the lower frame member that forms the lower side of the outer frameAnd a frame-like frame surrounding the output portion of the output device,First of the front plateWith the protective cover body of the output unit facing the opening, the sub-frame is brought into contact with the frame of the output device from the back side, and the sub-frame is attached to the back side of the front plate so that the output unit ButFirst of the front plateThe output device is mounted and fixed in a state facing the opening. In addition, the subframeFront plateBy attaching to the back side ofThe frame of the output device is in close contact with the plate-like portion of the subframe, the entire circumference of the contact portion of the protective cover body is in close contact with the frame of the output device, and the contact portion of the protective cover body and The entire circumference of each partition is in close contact with the back surface of the front plate.That is, the protective cover body of the output unit can be fixed without using screws or the like, so that the number of parts can be reduced and the cost can be reduced. Further, since the screw tightening work is reduced, the attaching work can be easily performed and the working time can be shortened. Furthermore,The frame of the output device is brought into close contact with the plate-like portion of the subframe, the entire circumference of the contact portion of the protective cover body is brought into close contact with the frame of the output device, and the contact portion of the protective cover body and By sticking the entire circumference of each partition against the back of the front plateIt is possible to suppress the formation of a gap between the members. As a result, the sound output to the front (rear) of the output unit does not pass through the rear (front) through a gap, and the cancellation of the sound due to the interference of the sound is prevented. You can play certain games.
[0092]
In addition, a housing case for housing the output device is disposed on the rear side of the output device, and an airtight housing portion is defined by the housing case and the front plate, so that the front and rear of the output device can be further improved. Interference of the output sound can be suppressed, and a clear sound can be output. In addition, since the bass reflex duct that connects the inside and the outside of the housing portion is provided, the low frequency range of the sound output from the output device can be enhanced, so that it is possible to output a realistic sound and powerful sound.
[0093]
In addition, a plurality of protrusions are formed on the back side of the front plate and at a required portion surrounding the opening, and a plurality of protrusions are allowed to be inserted into a portion of the subframe that is in contact with the output device frame. If the bottomed holes are correspondingly recessed and a protrusion is inserted into the bottomed hole, the subframe can be positioned at a predetermined position and temporarily fixed. That is, since the output device and the protective cover body can be easily positioned and temporarily fixed, the mounting operation can be made efficient and the working time can be shortened. In addition, if a through-hole penetrating the bottom of the bottomed hole is formed, when the subframe is temporarily fixed to the protrusion, a screw is inserted into the through-hole and screwed to the protrusion. The output device and the protective cover body can be easily fixed to the back side of the front plate.
[0094]
Furthermore, when the subframe is temporarily fixed, a slight gap is formed between the bottom of the bottomed hole and the top surface of the protrusion, thereby screwing the screw into the protrusion. Further, since the gap is crushed and retightening is allowed, a uniform pressing force can be applied over the entire circumference of the frame of the output device via the subframe. By forming a slight gap between the bottom of the bottomed hole and the top surface of the protrusion, and tightening it, the protective cover body is firmly attached to the frame and the back side of the front plate over the entire circumference. It is closely attached to. That is, the protective cover body can be prevented from falling off from the front plate, and the front and rear of the output unit can be more reliably separated from each other, and interference of sound output from the front and rear of the output device can be suppressed. In addition, since the output device is also firmly fixed, it is possible to reduce so-called chatter noise caused by resonance.
