As shown in FIG. 15, the front-rear direction dimension L3 of the wall part that forms the speaker housing region 261 is substantially the same as the front-rear direction dimension L4 of the lower frame part 11a of the outer frame 11.

  As shown in FIG. 17, a speaker 252 is accommodated in the speaker accommodation area 261. The speaker 252 is a well-known speaker device that has a cone shape and outputs sound by vibrating a diaphragm, and has a diameter on the front surface larger than a height dimension. In this case, the speaker 252 is the same as the speaker 252 provided in the speaker unit 26 of the front door frame 14 in the gaming machine main unit 12. Further, a plurality of passage holes 252a are formed on the back side of the speaker 252. When the diaphragm vibrates, sound is output from both the front side and the back side of the speaker 252.

  The speaker 252 is disposed downward with respect to the speaker housing area 261 and is fixed to the bottom plate portion 262 of the speaker housing area 261 with screws 263 as shown in FIG. In this case, the bottom plate portion 262 is formed with a through hole 264 that penetrates in the vertical direction and has a slightly smaller diameter than the front surface of the speaker 252. The front surface of the speaker 252 is located directly above the through hole 264, and the entire front peripheral edge of the speaker 252 is in close contact with the peripheral edge of the through hole 264 on the upper surface of the bottom plate portion 262. Since the speaker 252 is installed as described above, the sound output from the front side of the speaker 252 propagates downward of the speaker unit 250 through the through hole 264 as shown in FIG.

  Sound output from the back side of the speaker 252 propagates in the speaker housing 251. In this case, the speaker housing 251 functions as an enclosure, and as shown in FIG. 19, a bass reflex is provided at the end of the front plate portion 265 of the base body 253 opposite to the speaker housing region 261 side. A sound outlet 266 is formed as a port. Thereby, the sound output from the back side of the speaker 252 propagates toward the front of the speaker unit 250 through the internal region of the speaker housing 251 and the sound outlet 266. Incidentally, the sound outlet 266 is formed by a cylindrical body 267 fixed to the front plate portion 265.

  The electrical wiring 252 b for supplying operating power to the speaker 252 extends from the inner side plate portion 268 in the speaker housing region 261 to the outside of the speaker housing 251. Specifically, as shown in FIG. 17, the side plate portion 268 of the base body 253 has a recess 269 that is recessed downward from the upper end thereof, and the recess 269 has a size corresponding to the thickness of the electric wiring 252b. ing. And the upper cover body 254 is being fixed with respect to the base body 253 in the state which let the electrical wiring 252b pass to this recessed part 269. FIG.

  The speaker unit 250 described above is fixed to the lower frame portion 11 a of the outer frame 11. Specifically, the bottom plate portion 262 of the speaker housing 251 is screwed to the lower frame portion 11a from the inside (see FIG. 18). In addition, it is good also as a structure which forms the flange part for screwing in the outer periphery peripheral part of the baseplate part 262 of the speaker housing | casing 251, and screws the said flange part and the lower frame part 11a. In this case, the speaker unit 250 can be attached to and detached from the outer frame 11 without requiring removal of the upper lid 254 from the base body 253.

  In a state where the speaker unit 250 is fixed to the lower frame portion 11a, the front edge of the speaker unit 250 and the front edge of the lower frame portion 11a are at the same position, and the rear edge and lower frame portion of the speaker housing area 261 in the speaker unit 250 The rear edge of 11a is in the same position. Note that the front-rear direction dimension of the speaker unit 250 may be reduced by the thickness dimension of the curtain plate 19 so that the curtain plate 19 does not protrude forward of the pachinko machine 10 from the lower frame portion 11a.

  Further, the side end surface of the speaker unit 250 on the side where the sound outlet 266 is formed is in contact with the inner end surface of the base 20, and the side end surface outside the speaker accommodating region 261 in the speaker unit 250 is the right side of the outer frame 11. It contacts the inner plate surface of the frame portion 11c. Thus, the positioning in the left-right direction is performed by contacting the inner end surface of the base 20 and the inner plate surface of the right frame portion 11c. Incidentally, since the speaker unit 250 is installed as described above, the speaker 252 is located on the lower end portion of the gaming machine main body 12 on the lower frame portion 11a, and the sound outlet 266 is located on the lower frame portion 11a. At the pivot base end of the main part 12.

  The speaker housing 251 is formed with an extension region 270 that comes into contact with the right frame portion 11c of the outer frame 11 from the front side. The extension region 270 is formed on the right frame portion 11c side of the outer frame 11 with respect to the speaker housing region 261 so as to extend by the thickness of the right frame portion 11c, and the front-rear direction dimension is the right frame portion of the lower frame portion 11a. It is the part which extended ahead rather than 11c. Positioning in the front-rear direction is performed by bringing the extension region 270 into contact with the front surface of the right frame portion 11c in this way.

  Since the speaker unit 250 is fixed to the lower frame portion 11a, sound is output from the curtain region. Here, as described above, the sound output from the front surface side of the speaker 252 is propagated toward the lower side of the speaker unit 250, but the sound for guiding this sound to the front of the pachinko machine 10 in the lower frame portion 11a. A lead-out portion 271 is formed.

  Specifically, as shown in FIG. 18, the sound derivation unit 271 has a shape that is open at the top surface, bottom surface, and front surface of the lower frame portion 11a and that the left and right sides and the rear are closed by the lower frame portion 11a itself. ing. In this case, the portion (lower surface opening portion) opened downward in the sound derivation unit 271 is blocked by the installation base S of the pachinko machine 10 in the game hall (game room). That is, the sound derivation unit 271 is opened on the upper surface and the front surface of the lower frame portion 11a when the pachinko machine 10 is installed in the game hall. Further, the upper surface opening part 272 of the sound derivation part 271 has a circular shape, and the diameter thereof is the same as the diameter of the through hole 264 of the speaker housing 251. And the upper surface opening part 272 of the sound derivation | leading-out part 271 has overlapped with the through-hole 264 up and down. With the above configuration, the sound output from the front surface of the speaker 252 propagates toward the front of the pachinko machine 10 through the through hole 264 and the sound derivation unit 271.

  Incidentally, as described above, when the speaker unit 250 is installed with respect to the lower frame portion 11a, both the left-right direction and the front-rear direction are positioned. Since the positioning structure is provided in this way, when the speaker unit 250 is installed in the lower frame portion 11a, the through hole 264 of the speaker housing 251 and the upper surface opening portion 272 of the sound deriving portion 271 are naturally formed. Overlap each other. Therefore, the workability in installing the speaker unit 250 is improved.

  The electrical wiring 252 b of the speaker 252 drawn out of the speaker housing 251 is connected to the sound lamp control device 143. When the operating power is received from the sound lamp control device 143 through the electrical wiring 252b, the speaker 252 operates and outputs a sound. The sound output from the front side of the speaker 252 propagates toward the front of the pachinko machine 10 via the sound derivation unit 271 as described above. On the other hand, the sound output from the back side of the speaker 252 propagates toward the front of the pachinko machine 10 through the internal region of the speaker housing 251 and the sound outlet 266 as described above. Although the curtain plate 19 is provided in front of the speaker unit 250, a speaker hole 19a is formed in a portion of the curtain plate 19 located in front of the sound outlet 266. The output sound is not blocked by the curtain plate 19.

  Here, when sound is output from the speaker 252, the reverse action is performed on the front side and the back side of the speaker 252 with the diaphragm as a boundary. Specifically, for example, when the diaphragm moves to the front side of the speaker 252, air is pressed on the front side of the speaker 252 to become “dense”, while the back side becomes “sparse” with thin air, and the diaphragm Moves to the back side of the speaker 252, air is pushed to become “dense” on the back side of the speaker 252, while the front side becomes “sparse” with thin air. That is, sound waves having an opposite phase relationship are output to the front side and the back side of the speaker 252. In this case, it is known that if the sound wave output from the front side of the speaker 252 interferes with the opposite phase sound wave output from the back side, the sound transmitted to the player will be blurred by canceling each other. . In particular, the influence on the low-frequency sound having a long wavelength is remarkable, which causes a decrease in force and realism.

  On the other hand, since the front peripheral edge of the speaker 252 is in close contact with the bottom plate 262 as described above, the bottom plate 262 functions as a baffle plate, and the front side and the back side of the speaker 252 are It is separated. Therefore, the interference between the sound wave output from the front side of the speaker 252 and the sound wave output from the back side is suppressed, and sound output from the speaker 252 is favorably performed.

  In order to enhance the sound in the low frequency range, it is preferable to ensure a long distance from the speaker 252 to the sound outlet 266. On the other hand, as described above, the speaker 252 is on the rotating tip of the gaming machine main part 12 on the lower frame part 11a, and the sound outlet 266 is on the rotating base of the gaming machine main part 12 on the lower frame part 11a. At the end. Therefore, a long distance from the speaker 252 to the sound outlet 266 is secured, and the sound in the low frequency range can be enhanced.

  Further, the sound derivation portion 271 is located at the end of the lower end portion 11a on the rotating front end side of the gaming machine main portion 12, and the sound outlet 266 is the rotation base end of the gaming machine main portion 12 in the curtain region. Located at the end of the side. That is, the sound output from the front side and the back side of the speaker 252 is propagated from the left and right ends of the pachinko machine 10 toward the front of the pachinko machine 10. A storage box for storing game balls is arranged below the lower plate 34 of the pachinko machine 10, but as described above, sound is propagated from the left and right ends of the pachinko machine 10 toward the front of the pachinko machine 10. By doing so, it is possible to prevent the sound output from the speaker 252 from being blocked by the storage box.

  Since the speaker unit 250 is provided in the curtain region, the gaming machine main part 12 is positioned above the speaker unit 250 when the gaming machine main part 12 is closed with respect to the outer frame 11. In this case, the speaker unit 250 receives the weight of the gaming machine main part 12. Such a configuration will be described below.

  As shown in FIG. 17 and the like, the upper cover 254 of the speaker housing 251 is provided with a plurality of metal plates (support plates) 275 on the upper surface thereof. Specifically, two metal plates 275 are provided. These metal plates 275 are formed of the same material, have the same size and shape, and are provided at a position closer to the front of the upper lid 254. One metal plate 275 is provided from the upper part of the extension region 270 to the upper part of the speaker housing region 261, and the other metal plate 275 is provided near the sound outlet 266.

  The metal plate 275 is fixed to the upper lid body 254 by screwing screws (support plate fixtures) 276 from above. In this case, as shown in FIG. 18, the upper end of the head of the screw 276 is at the same height or lower than the upper surface of the metal plate 275, and the screw 276 does not protrude above the metal plate 275. The upper surface of the metal plate 275 is higher than the upper surface of the upper lid 254 by the thickness of the metal plate 275.

  In a state where the gaming machine main part 12 is closed with respect to the outer frame 11, the lower end part of the gaming machine main part 12 is placed on each metal plate 275 as shown in FIG. 18. Thereby, a part of the weight load of the gaming machine main part 12 is applied to each metal plate 275, and the weight load applied to the metal plate 275 is received by the speaker unit 250. In this way, by receiving a part of the weight load of the gaming machine main part 12 by the speaker unit 250, when the gaming machine main part 12 is in the closed state, the speaker housing 251 of the speaker unit 250. The upper lid body 254 is pressed toward the base body 253, and the upper lid body 254 and the base body 253 are brought into close contact with each other.

  As described above, the internal area of the speaker housing 251 functions as an enclosure. And in order to exhibit the function as this enclosure effectively, it is so preferable that the sealing property of the speaker housing | casing 251 is high. Under such circumstances, as the upper lid 254 and the base body 253 are brought into close contact with each other as described above, the sealing performance of the speaker housing 251 is enhanced, and the function as an enclosure is effectively exhibited in the speaker housing 251. Thereby, the sound quality of the sound output from the back side of the speaker 252 is improved.

  Incidentally, as described above, the outer frame 11 is provided with the lower support bracket 18 and the base 20, and the lower support bracket 18 and the base 20 can receive the weight load of the gaming machine main part 12. As shown in FIG. 15 and the like, the speaker unit 250 does not overlap the lower support bracket 18 and the base 20 in the front-rear direction and the vertical direction. Therefore, the weight load received by the lower support bracket 18 and the base 20 is not applied to the speaker unit 250. The lower support bracket 18 has a function of rotatably supporting the gaming machine main part 12, and when the gaming machine main part 12 is opened with respect to the outer frame 11, most of the weight load is large. It will be hung on the lower support bracket 18. In this case, the gaming machine main part 12 is opened to the outer frame 11 by preventing the weight load received by the lower support bracket 18 and the base 20 from being applied to the speaker unit 250 as described above. In this case, it is possible to prevent the speaker unit 250 from being damaged due to a heavy weight load applied to the speaker unit 250.

  Further, the metal plate 275 has an inclined portion 277 that is inclined downward toward the front of the pachinko machine 10 at the front end portion thereof. Thereby, when the gaming machine main part 12 is moved from the open state to the closed state, the lower end part of the gaming machine main part 12 is guided on the metal plate 275 by the inclined part 277, and the gaming machine main part 12 is placed on the metal plate 275. The part 12 is easily placed.

  Next, maintenance work for the speaker 252 will be described.

  When performing maintenance work on the speaker 252, the gaming machine main part 12 is first opened with respect to the outer frame 11. In this case, it is necessary to release the locked state of the gaming machine main part 12 with respect to the outer frame 11 by the locking device 131. By making the gaming machine main part 12 open, the entire upper surface of the speaker unit 250 is exposed.

  Thereafter, the fixing of the base body 253 and the upper lid body 254 of the speaker housing 251 is released. Specifically, the screw 257 is detached from above the upper lid body 254. The upper lid body 254 can be removed from the base body 253 by performing such a detachment operation on all the screws 257. Then, by removing the upper lid body 254, the inside of the speaker housing 251 is exposed, and the speaker 252 housed in the speaker housing 251 is exposed. Thereby, the back side of the speaker 252 can be cleaned. When it is necessary to remove the speaker 252, the screw 263 is detached from above the bottom plate portion 262 of the base body 253. The speaker 252 can be detached from the base body 253 by performing such a detachment operation on all the screws 263. Thereby, cleaning of the front side of the speaker 252 or replacement of the speaker 252 can be performed.

  Here, as described above, the speaker 252 is installed in the speaker housing 251 at the end of the gaming machine main body 12 on the rotating front end side. Therefore, the speaker 252 is close to the maintenance worker, and the task can be relatively easily performed when the speaker 252 is cleaned or replaced.

  After the cleaning or replacement of the speaker 252 is completed, an operation opposite to the above operation is performed. That is, the upper lid body 254 is placed on the base body 253, and the base body 253 and the upper lid body 254 are fixed by the screws 257. Thereafter, the gaming machine main part 12 is closed with respect to the outer frame 11. Thereby, the maintenance work of the speaker 252 is completed.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 20, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

In this case, a power supply and launch control board 321 is connected to the power failure monitoring circuit 303, and power is supplied to the CPU 311 (main control circuit 302) via the power failure monitoring circuit 303.

  On the other hand, a power failure monitoring circuit 303, a payout control board 322 and a relay terminal board 323 are connected to the output side of the CPU 311. Various commands such as a prize ball command are output to the payout control board 322. Various commands and the like are output from the main control circuit 302 to the sound lamp control board 324 provided in the sound lamp control device 143 via the relay terminal plate 323.

  The power failure monitoring circuit 303 relays between the main control circuit 302 and the power source and launch control board 321, and monitors a DC stable voltage of 24 volts that is the maximum voltage output from the power source and launch control board 321. When this voltage is 22 volts or more, a power failure signal is output to the main control circuit 302. The main control circuit 302 confirms the input of the power failure signal, and executes a power failure process (power failure process) based on the confirmation result.

  The payout control board 322 performs payout control of prize balls and rental balls by the payout device 224. The CPU 331 that is an arithmetic unit includes a ROM 332 that stores a control program executed by the CPU 331, fixed value data, and the like, and a RAM 333 that is used as a work memory or the like.

  Similar to the RAM 313 of the main control circuit 302, the RAM 333 of the payout control board 322 is configured to retain data by supplying the data storage holding power from the power supply and the launch control board 321 even after the power of the pachinko machine 10 is shut off.

  The power source and launch control board 321 includes a power source unit 321a and a launch control unit 321b. The power supply unit 321a is connected to, for example, a commercial power supply (external power supply) in a game hall or the like. Then, based on the external power supplied from the commercial power supply, necessary operating power is generated for each of the main control circuit 302, the payout control board 322, etc., and the generated operating power is indicated by a double line arrow. This is supplied to the main control circuit 302 and the payout control board 322 through the path.

  The launch control unit 321b is responsible for launch control of the game ball launching mechanism 110 in accordance with the operation of the game ball launch handle 41 by the player, and the game ball launching mechanism 110 is driven when predetermined launch conditions are met. The

  In addition, the data storage holding capacitor 321c is mounted on the power supply and launch control board 321. The power storage unit 321a is connected to the data storage / holding capacitor 321c, and is stored when the power of the pachinko machine 10 is ON. In addition, the data storage holding capacitor 321c is connected to the VBB terminal of the CPU 311 in the main control circuit 302. When the power of the pachinko machine 10 is in an OFF state or when a power failure occurs in a commercial power supply, the data storage The storage capacitor 321 c is discharged, and the data storage holding power is supplied to the RAM 313. Therefore, even in such a situation, while the data storage holding power is supplied from the data storage holding capacitor 321c, the data stored in the RAM 313 is held without being erased. Incidentally, the capacity of the data storage holding capacitor 321c is relatively large, and the information stored in the RAM 313 before the power is shut off is held within a predetermined period (for example, 1 day or 2 days).

  The power supply and launch control board 321 is provided with a power failure processing capacitor different from the data storage holding capacitor 321c. In the power source and launch control board 321, even after the DC stable 24 volt power source becomes less than 22 volts, by discharging from the power failure processing capacitor, a time sufficient for execution of the power failure processing described later, The output of 5 volts, which is a drive power source for the control system, is configured to maintain a normal value. Thereby, the main control circuit 302 and the like can normally execute and complete the power failure process.

The main control circuit 302 is connected to the input side of the CPU 341 by relaying to the relay terminal plate 323, and based on various commands output from the main control circuit 302, the speakers 28 and 252, the various lamp units 23 to 25, and The display control device 325 is controlled. The display control device 325 controls the symbol display device 91 based on a display command input from the sound lamp control board 324.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  The speaker unit 250 is provided by effectively utilizing the curtain plate region between the lower frame portion 11a of the outer frame 11 and the gaming machine main portion 12. In this case, the speaker 252 is installed downward. Here, in the curtain plate region, the vertical dimension is defined by the lower frame part 11a and the gaming machine main part 12, but the longitudinal dimension is not defined by these. In general, the front and rear dimension of the lower frame portion 11a is larger than the vertical dimension of the curtain plate region. In such a situation, by installing the speaker 252 downward as described above, it is possible to increase the diameter of the speaker 252 compared to a configuration in which the speaker 252 is installed facing the front of the pachinko machine 10, The sound quality of the sound output from the speaker 252 is improved. Further, in the configuration in which the speaker 252 is installed downward as described above, since the sound deriving unit 271 is formed in the lower frame portion 11a, the sound output from the front side of the speaker 252 is derived to the sound deriving unit 271. Then, it will propagate toward the front of the pachinko machine 10, and the player can watch the sound. Note that dust and the like are prevented from being collected on the front side of the speaker 252 by installing the speaker 252 downward.

  The sound deriving portion 271 is configured to communicate with the front surface of the lower frame portion 11a from the lower position of the speaker 252 on the upper surface of the lower frame portion 11a, and at least the left and right sides and the rear side are closed. Thereby, the sound output from the front side of the speaker 252 can be propagated toward the front of the pachinko machine 10, and at least the left and right sides and the rear side of the sound deriving unit 271 are closed, so that the sound deriving unit 271 Sound leakage is reduced, and the sound output from the front side of the speaker 252 can be efficiently guided to the front of the pachinko machine 10.

  Further, the sound derivation portion 271 is formed so as to be opened downward on the bottom surface of the lower frame portion 11a. That is, the sound deriving portion 271 is formed so as to be opened at the upper surface, the front surface, and the bottom surface in the lower frame portion 11a, and can be formed easily compared to a configuration in which only the upper surface and the front surface are opened. Is achieved. Moreover, in the said structure, since the lower open part is obstruct | occluded by the installation stand S of the pachinko machine 10 in a game hall, the sound output from the front side of the speaker 252 can be guide | induced to the front of the pachinko machine 10 efficiently.

  A sound outlet 266 is formed in the front plate portion 265 of the speaker housing 251 so that sound output from the back side of the speaker 252 is propagated toward the front of the pachinko machine 10 through the internal region of the speaker housing 251 and the sound outlet 266. I made it. Since the sound output from the back side of the speaker 252 propagates through the internal region of the speaker housing 251, it is possible to output a sound with an increased volume in the low sound range from the sound outlet 266. In particular, the speaker 252 is on the rotating distal end side of the gaming machine main portion 12 on the lower frame portion 11a, and the sound outlet 266 is on the rotating proximal end side of the gaming machine main portion 12 on the lower frame portion 11a. Therefore, a long distance from the speaker 252 to the sound outlet 266 is secured, and the sound in the low frequency range can be enhanced.

  In a state in which the speaker housing 251 is composed of a base body 253 that is opened upward and an upper lid body 254 that closes the upper surface opening portion of the base body 253, and the gaming machine main part 12 is closed with respect to the outer frame 11, The upper lid 254 receives a part of the weight of the gaming machine main part 12 from below. As a result, when the gaming machine main part 12 is closed, the upper lid 254 is pressed downward by the weight of the gaming machine main part 12, so that the upper lid 254 and the base body 253 come into close contact with each other. The hermeticity is improved. Therefore, the function of the speaker housing 251 as an enclosure is enhanced, and sound output by the speaker unit 250 can be performed satisfactorily. In addition, a metal plate 275 is provided on the upper surface of the upper lid body 254, and the metal plate 275 is interposed between the upper lid body 254 and the lower end portion of the gaming machine main portion 12 when the gaming machine main portion 12 is closed. As a result, the upper lid body 254 made of synthetic resin receives the weight of the gaming machine main part 12 indirectly rather than directly, and the upper lid 254 is damaged when receiving the weight of the gaming machine main part 12. Is suppressed.

  The speaker 252 of the speaker unit 250 is the same speaker as the speaker 252 mounted on the front frame portion 14 of the gaming machine main unit 12. Thereby, in the structure provided with the some speaker 28,252, commonality of a speaker is achieved and member management can be performed suitably.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (1) The modification regarding the speaker unit in the said embodiment is shown to FIG.

  (1-1) In the modification shown in FIG. 21, the speaker unit 370 differs from the speaker unit 250 in the above embodiment in that the inner region of the speaker housing 371 is partitioned on the left and right by a partition wall 372. One speaker 375 and 376 is accommodated in each of the right region 373 and the left region 374.

In addition, a sound outlet 379 similar to that of the above embodiment is formed at the left end portion of the front plate portion 378 of the speaker housing 371 (that is, the end portion on the rotating base end side of the gaming machine main portion 12). . Thereby, the sound output from the front side of the first speaker 375 propagates toward the front of the pachinko machine 10 through the sound deriving unit 271, and the sound output from the back side of the first speaker 375 It will propagate toward the front of the pachinko machine 10 through 379.

  A speaker 376 (hereinafter also referred to as a second speaker 376) housed in the left region 374 is installed facing forward. In this case, a sound outlet 380 is formed in the front plate portion 378 of the speaker housing 371 in front of the second speaker 376, and sound output from the front side of the second speaker 376 passes through the sound outlet 380. 10 will propagate toward the front. However, the left region 374 is a sealed type so that the sound output from the back side of the second speaker 376 does not leak outside the left region 374. That is, the right region 373 has a function as a phase inversion type enclosure, while the left region 374 has a function as a sealed enclosure.

  As described above, the right side region 373 and the left side region 374 are provided in the speaker housing 371, and the speakers 375 and 376 are provided in the respective regions 373 and 374. It is possible to realize the output of sound in the middle and high range by the left region 374 and the second speaker 376. Particularly, since the first speaker 375 is installed downward as in the above embodiment, the diameter of the first speaker 375 can be increased, and the low-frequency sound can be output at a high volume. Can do.

  Also in this configuration, the speaker housing 371 includes the base body 253 and the upper lid body 254 as in the above embodiment, and the gaming machine main section 12 is in a state where the gaming machine main section 12 is closed to the outer frame 11. The upper lid body 254 is pressed from above, and the base body 253 and the upper lid body 254 come into close contact with each other. Therefore, the airtightness between the base body 253 and the upper lid body 254, that is, the airtightness of the right region 373 and the left region 374 is enhanced. Note that the gaming machine main part 12 may not be placed on the speaker housing 371 in a state where the gaming machine main part 12 is closed to the outer frame 11.

  (1-2) In the modification shown in FIG. 22, the speaker unit 390 is installed between the lower end portion of the gaming machine main portion 12 and the lower frame portion 11a of the outer frame 11 as in the above embodiment. . The speaker unit 390 includes a speaker 391, and the speaker 391 is installed downward. In addition, a sound derivation unit 271 is formed in the lower frame portion 11a as in the above embodiment, and the sound output from the front side of the speaker 391 propagates toward the front of the pachinko machine 10 through the sound derivation unit 271. . In addition, a sound outlet 394 is formed in the front plate portion 393 of the speaker housing 392, and sound output from the back side of the speaker 391 propagates toward the front of the pachinko machine 10 through the sound outlet 394. Thereby, the sound quality of the sound output from the speaker unit 390 is improved. In this configuration, no curtain is provided.

  In the above configuration, the speaker unit 390 does not receive the weight of the gaming machine main part 12 when the gaming machine main part 12 is closed with respect to the outer frame 11. More specifically, the outer frame 11 is provided with a base 20 for supporting the lower support bracket 18 from below at the end of the gaming machine main part 12 on the rotation base end side, and the gaming machine main part. A base 395 is also provided at the end of the twelve rotation tip side. The speaker unit 390 is installed between the two bases 20 and 395. In addition, the height position of the upper surface of the base 395 is the same as the height position of the upper surface of the combination of the lower support bracket 18 and the base 20, and the height position of the upper surface of the speaker unit 390 is the base 395. It is a position lower than the height position of the upper surface. Therefore, in a state where the gaming machine main part 12 is closed to the outer frame 11, the turning base end side of the gaming machine main part 12 is placed on the base 20, and the turning distal end side of the gaming machine main part 12 is placed on the base 395. A gap corresponding to a distance X is generated between the lower end of the gaming machine main unit 12 and the speaker unit 390. Therefore, the gaming machine main part 12 is not placed on the speaker unit 390, and the speaker unit 390 does not receive the weight of the gaming machine main part 12. In this configuration, the upper lid 396 is not pressed downward by the gaming machine main part 12, so that the sealing performance of the speaker casing 392 cannot be improved as in the above embodiment, but the gaming machine main part 12 is connected to the speaker casing 392. The weight of the speaker housing 392 is prevented from being damaged.

  In this configuration, the speaker housing 392 may be opened from the rear or the front instead of being opened from the top.

  (2) In the speaker unit 250, in order to make the sound propagation distance from the speaker 252 to the sound outlet 266 longer than that in the above embodiment, a pachinko machine is provided between the speaker 252 and the sound outlet 266 in the speaker housing 251. The sound path may be formed by detouring in the 10 front-rear direction and the left-right direction. In this case, the propagation distance of the sound output from the back side of the speaker 252 in the speaker housing 251 is increased, and the bass enhancement effect is enhanced as compared with the above embodiment. Moreover, it is good also as a shape which a cross-sectional area increases continuously or intermittently toward this sound path toward the downstream, and the enhancement effect of a bass is further enhanced in this case.

  (3) The sound derivation part 271 may be closed also by the lower frame part 11a itself, rather than being opened downward in the lower frame part 11a. In this case, the sound derivation part 271 is opened only on the upper surface and the front surface in the lower frame part 11a, and the other parts are closed. According to this configuration, the formation of the sound deriving portion 271 is more difficult than in the above embodiment, but the lower frame portion 11a itself closes the sound deriving portion 271. The lower part is securely closed.

  (4) In the sound deriving unit 271, in order to make the sound propagation distance from the speaker 252 to the exit of the sound deriving unit 271 longer than in the above embodiment, the front and rear direction and the left and right direction of the pachinko machine 10 in the sound deriving unit 271 The sound path may be formed by detouring. In this case, also for the sound output from the front side of the speaker 252, the propagation distance in the sound deriving unit 271 is increased, and the bass enhancement effect is enhanced. Moreover, it is good also as a shape which a cross-sectional area increases continuously or intermittently toward this sound derivation | leading-out part 271 toward a downstream, and the enhancement effect of a bass is further heightened in this case.

  (5) In the speaker unit 250, the size in the front-rear direction of the speaker housing area 261 may be larger than that in the above embodiment. For example, the speaker housing area 261 may be extended rearward from the rear end portion of the lower frame portion 11a. Thereby, the speaker 252 having a larger aperture than that of the above embodiment can be installed.

  (6) In the above embodiment, only the speaker housing area 261 in the speaker housing 251 bulges rearward compared to other areas, but instead, it is arranged on the left side of the speaker housing area 261. The area may bulge rearward from the above embodiment, and the rear end face of the area may be located on the same plane as the rear end face of the speaker housing area 261.
