Description

  The present invention relates to a gaming machine.

  A pachinko machine, which is a type of gaming machine, includes a speaker device, and attention to the game is increased by outputting various sounds from the speaker device according to the gaming state. In addition, it is considered that the degree of attention to the game can be increased by improving the sound quality of the sound output from the speaker device.

  In order to improve the sound quality, it is necessary that at least the sound output from the front side of the speaker device does not cancel out the sound output from the back side of the speaker device. As a pachinko machine that achieves high sound quality by suppressing cancellation of such sounds, for example, in Patent Document 1, a speaker mounting base is attached to the front of a gaming machine base having a gaming board and below the gaming board, A configuration is disclosed in which the speaker device is attached so that the front side of the speaker device faces the front of the pachinko machine with respect to the front side of the mounting base. In this case, sound from the back side of the speaker device is output to the enclosure formed by the speaker mounting base and the gaming machine base. Thereby, it is suppressed that the sound output from the back side of the speaker device is propagated to the front side of the mounting base while being in an opposite phase to the sound output from the front side of the speaker device. As the cancellation of the sound is suppressed, higher sound quality is achieved.

A series of front edge frame portions 112 formed so as to protrude from the front wall portion 111 to the rear of the base frame 51 so as to define the outer peripheral portion of the 51 is provided. Further, a rear wall portion 113 having wall surfaces facing the front and rear sides of the pachinko machine 10 in the resin base 21 on the outer peripheral portion of the resin base 21 in the gaming machine base unit 13 corresponding to the front edge frame portion 112. A series of rear side edge frame portions 114 are integrally formed so as to protrude forward from the resin base 21. A series of stepped portions 115 are formed on the rear edge frame portion 114 from the inner side to the outer side in the middle of the projecting direction, and the stepped portion 115 is compared to the inner peripheral surface on the base side of the stepped portion 115. The inner peripheral surface on the tip side is located on the outer peripheral side of the pachinko machine 10.

  In the closed state of the gaming machine front unit 14, the rear edge frame portion 114 is located on the outer peripheral side of the pachinko machine 10, so that the front edge side of the front edge frame portion 112 and the rear edge frame portion 114 from the step 115. Also, the leading end side overlaps with the inside and outside, and an overlapping area between the inside and outside of the front edge frame portion 112 and the rear edge frame portion 114 is formed over the entire outer periphery of the pachinko machine 10. In this case, a series of rubber packings 117 are provided on the stepped portions 115 forming a series of facing surfaces facing the projecting side end surface 116 of the front edge frame portion 112 as a sealing improvement means. In the closed state of the unit 14, the rubber packing 117 is sandwiched between the protruding side end surface 116 and the step portion 115 and is in a compressed state. Thereby, the airtightness of the space between the gaming machine front unit 14 and the gaming machine base unit 13 is enhanced.

  A space between the gaming machine front unit 14 and the gaming machine base unit 13 from the outer circumferential side of the pachinko machine 10 is provided by forming an overlapping region in the outer circumferential part of the pachinko machine 10 and providing the rubber packing 117. It is possible to make it difficult to perform an act of inserting a fraudulent jig into the inside.

  Further, as already described, the window panel unit 53 is attached to the base frame 51 from the back side. The window panel unit 53 protrudes from the front wall portion 111 to the rear of the base frame 51. In addition, although this protrusion amount is substantially the same as the protrusion amount from the front wall part 111 of the front side edge frame part 112, it is not limited to this, The same protrusion amount may be sufficient. Obviously a large configuration may be used.

  The peripheral portion 121 of the window hole 22 formed for exposing the game area in the resin base 21 accommodates the window panel unit 53 attached so as to protrude rearward from the front wall portion 111 as described above. A configuration is provided. Specifically, as shown in FIGS. 5 and 7, the peripheral portion 121 of the window hole 22 has a series of stepped portions 122 extending from the inside to the outside of the window hole 22 at a midway position in the penetration direction of the window hole 22. The inner peripheral surface on the base frame 51 side with respect to the stepped portion 122 is located on the outer peripheral side of the window hole 22 as compared with the inner peripheral surface on the game board 23 side with respect to the stepped portion 122. For convenience of explanation, the stepped portion 122 is omitted in FIG.

  In the closed state of the gaming machine front unit 14, the outer peripheral surface of the panel frame 54 overlaps the inner peripheral surface in the region closer to the base frame 51 than the stepped portion 122 in the peripheral portion 121. Such an overlap region is formed over the entire circumference of the window hole 22. However, as shown in FIG. 2, the window hole 22 is partially cut downward so that the return sphere can be recovered by the return sphere recovery portion 77. Overlapping areas are not formed. In this case, as shown in FIG. 5 and FIG. 7, a series of rubber packings 123 are provided as sealing means for the stepped portion 122 that forms a series of facing surfaces facing the back surface of the panel frame 54. In the closed state of the gaming machine front unit 14, the rubber packing 123 is sandwiched between the back surface of the panel frame body 54 and the stepped portion 122 and is in a compressed state. Thereby, the airtightness of the space between the game board 23 and the window panel unit 53 is improved.

  An overlapping region is formed between the peripheral edge 121 of the window hole 22 and the window panel unit 53 and the rubber packing 123 is provided, so that the gaming machine front unit 14 and the game are played from the outer peripheral side of the pachinko machine 10. Even if the fraudulent jig is inserted into the space between the machine base unit 13, it is possible to prevent the fraudulent jig from entering the game area.

  As shown in FIG. 2, on the back surface of the front wall 111 in the base frame 51, a predetermined range including a location where one speaker device 63 is provided and a predetermined range including a location where the other speaker device 64 is provided. In this area, front recessed areas 131 and 132 that are recessed forward of the pachinko machine 10 from the rear surface of the window panel unit 53 and the protruding end face 116 of the front edge frame portion 112 are formed. One of the front recessed regions 131 and 132 is formed so as to include a corner portion of the upper part (upper right) of the rotation front end side of the base frame 51, and the other is an upper part of the rotation base end side of the base frame 51 ( It is formed so as to include the upper left corner portion. Both front recessed areas 131 and 132 are each partitioned by an inner peripheral surface of the front edge frame portion 112 and an outer peripheral surface of the panel frame body 54, and a plurality of partition walls (front side) formed on the back surface of the front wall portion 111. (Partition part) 133,134,135.

  As shown in FIG. 2, each partition wall 133 to 135 has a rearward projecting amount with respect to the front recessed regions 131 and 132 as compared to the rear surface of the window panel unit 53 and the projecting side end surface 116 of the front edge frame portion 112. Further, it is continuous from the inside with respect to the front edge frame portion 112 and is in contact with the outer peripheral surface of the panel frame body 54 from the outside. The area where the partition walls 133 to 135 are in contact with each other on the outer peripheral surface of the panel frame 54 is an area that does not enter the window hole 22 of the resin base 21 when the gaming machine front unit 14 is in a closed state.

  Of the partition walls 133 to 135, both front-side recessed regions 131 and 132 are partitioned right and left above the window panel unit 53 by an upper partition wall 133 formed at the upper part of the back surface of the front wall portion 111. Of the partition walls 133 to 135, the front side dent on the rotary front end side of the front side dent regions 131 and 132 is formed by the front side partition wall 134 formed on the back side of the front wall 111. A lower edge in the region 131 is defined. Of the partition walls 133 to 135, the base end side partition wall 135 formed on the back base end side on the back surface of the front wall portion 111 causes the rotation base end side of both front recessed regions 131 and 132. The lower edge of the front recessed area 132 is defined. The partition walls 133 to 135 also function as reinforcing ribs in the base frame 51.

  Corresponding to the formation of the front recessed areas 131 and 132 in the front wall 111, the rear recessed areas 141 and 142 are formed in the rear wall 113 of the resin base 21. One of the rear recessed areas 141 and 142 corresponds to the front recessed area 131 on the rotating front end side, and is formed so as to include the corner portion of the upper part (upper right) of the rotating front end side of the resin base 21. The other corresponds to the front recessed region 132 on the rotation base end side, and is formed so as to include the corner portion of the upper part (upper left) of the resin base 21 on the rotation base end side. Both of the rear recessed areas 141 and 142 are partitioned by the inner peripheral surface of the rear edge frame portion 114 and the outer peripheral surface of the panel frame body 54, and a plurality of partition walls formed on the front surface of the rear wall portion 113. (Rear partitioning portions) 143, 144, and 145.

  As shown in FIG. 2, each of the partition walls 143 to 145 has a forward protrusion amount with respect to the rear recessed regions 141 and 142 as a reference, and the front end portion and the rear edge frame portion 114 in the peripheral portion 121 of the window hole 22. The rear edge frame 114 is continuous from the inner side with respect to the root side than the stepped portion 115, and the outer periphery of the panel frame body 54. It touches the surface from the outside. Each of the partition walls 143 to 145 is formed with an overlapping allowance space so as not to hinder the inner and outer overlap of the rear edge frame portion 114 and the front edge frame portion 112.

  Of the partition walls 143 to 145, both rear recessed regions 141 and 142 are partitioned right and left above the window hole 22 by an upper partition wall 143 formed at the upper portion of the front surface of the rear wall portion 113. Further, among the partition walls 143 to 145, the rear side partition wall 144 formed on the rear side of the rear wall portion 113 on the rear side of the rotary front side causes the rear side of the rotary front side of the rear side recessed regions 141 and 142. A lower edge in the side recessed area 141 is defined. Further, of the partition walls 143 to 145, the rotation base end of the rear recessed regions 141 and 142 is formed by the base end side partition wall 145 formed on the rotation base end side on the back surface of the rear wall portion 113. A lower edge in the side rear recessed area 142 is defined. The partition walls 143 to 145 also function as reinforcing ribs in the resin base 21.

  In the closed state of the gaming machine front unit 14, as shown in FIG. 6, the protruding side end surface of the upper partition wall 133 formed in the front wall portion 111 and the protruding side of the upper partition wall 143 formed in the rear wall portion 113. The end face overlaps the front and rear. Similarly, the protruding end surface of the partition wall 134 on the rotating tip side formed on the front wall portion 111 and the protruding side end surface of the partition wall 144 on the rotating tip side formed on the rear wall portion 113. Are overlapped in the front-rear direction, on the protruding side end surface of the rotation base end side partition wall 135 formed on the front wall portion 111, and on the rotation base end side partition wall 145 formed on the rear wall portion 113. The protruding side end surface overlaps the front and rear. As a result, as shown in FIG. 1, a closed space 151 is formed by the front recessed area 131 and the rear recessed area 141 on the rotating distal end side, and the front recessed area 132 and the rear recessed area on the rotating proximal end side. A closed space 152 is formed by the region 142. One speaker device 63 is disposed on the front wall portion 111 that defines the front side of the closed space 151 on the rotating distal end side, and the front wall that defines the front side of the closed space 152 on the rotating proximal end side. The other speaker device 64 is arranged with respect to the unit 111.

  Hereinafter, for convenience of explanation, the speaker device 63 and the closed space 151 on the rotating distal end side are referred to as a first speaker device 63 and a first closed space 151, and the speaker device 64 and the closed space 152 on the rotating proximal end side are referred to as a second. The speaker device 64 and the second closed space 152 are referred to. Since the first closed space 151 and the second closed space 152 have the same configuration, the configuration of the first closed space 151 will be described in detail, and the second closed space 152 has the same configuration. Description is omitted as it is.

  In the first closed space 151, the area of the front wall 111 that defines the front side of the first closed space 151 functions as a baffle plate for the first speaker device 63, and the first closed space 151 is the first speaker device 63. Sound is output from the back side of the first speaker device 63 into the first closed space 151.

  As shown in FIGS. 5 and 7, a through-hole 153 in the front-rear direction is formed in a region defining the first closed space 151 in the rear wall 113, and the through-hole 153 in the game board 23 extends in the front-rear direction. A through-hole 154 in the front-rear direction is also formed in the overlapping region, and an opening hole 155 is formed by communicating these through-holes 153 and 154. The opening hole 155 is linearly formed over the entire hole length direction, and the hole diameter is the same. The opening hole 155 is formed as a hole having a circular cross section, but is not limited thereto, and may be formed as a hole having a square cross section.

  The opening hole 155 is disposed at a position where the central axis A2 extending in the hole length direction of the opening hole 155 is not collinear with the central axis A1 extending in the thickness direction of the first speaker device 63. Specifically, the opening hole 155 is located at a position outside the region behind the pachinko machine 10 of the opening 105 formed in the front wall 111, in other words, the opening 105 toward the rear of the pachinko machine 10. It is formed at a position outside the projection range. In more detail, the opening hole 155 is located at a position outside the region behind the pachinko machine 10 of the first speaker device 63, in other words, the projection range of the first speaker device 63 to the rear of the pachinko machine 10. It is formed at a position deviated from.

  Further, as shown in FIG. 5 and FIG. 7, the opening hole 155 has a first area with respect to a region constituting the peripheral surface of the first closed space 151 between the front wall portion 111 and the rear wall portion 113. It is formed at a position spaced inside the closed space 151. That is, while being separated from the overlapping region of the front edge frame portion 112 and the rear edge frame portion 114 inside the first closed space 151, the first region is overlapped with the overlapping region of the window hole 22 and the window panel unit 53. An opening hole 155 is formed at a position spaced inside the closed space 151 and further spaced inside the first closed space 151 with respect to the overlapping region of the partition walls 133, 143, 134, and 144. .

  The opening hole 155 opens the first closed space 151 to the rear of the game board 23, that is, the space behind the gaming machine base unit 13. Here, in the configuration in which sound is output from the back surface of the first speaker device 63 to the enclosure, the vibration of the diaphragm of the first speaker device 63 is easily suppressed by the viscosity of the air surrounded by the enclosure. In this case, in order to exert the bass reproduction capability of the sound output from the first speaker device 63, conditions such as a large volume of the enclosure and a large diameter of the first speaker device 63 are known. Yes. However, since various members such as the window panel unit 53, the upper plate 73, and the lower plate 74 are arranged on the front unit 14 of the gaming machine, there is a limit in trying to increase the size of the first speaker device 63. Since it is necessary to install the pachinko machine 10 in the existing island facilities in the hall, there is a limit to increasing the thickness, vertical and horizontal dimensions of the pachinko machine 10, and accordingly the enclosure volume is increased. There is a limit to trying to. On the other hand, since the opening hole 155 is formed as described above, the vibration of the diaphragm of the first speaker device 63 is hardly suppressed.

  As shown in FIG. 5, the opening hole 155 has a predetermined length L that is the sum of the thickness of the rear wall 113 and the thickness of the game board 23, and has a predetermined hole diameter Ra. Have. In this case, the hole diameter Ra is set so that the opening hole 155 functions as a bass reflex port for resonating a sound having a predetermined specific frequency in the low sound range. The hole diameter Ra is calculated and set using the following Helmholtz equation so that resonance occurs at a specific frequency in relation to the volume V in the first closed space 151 and the length L of the opening hole 155. Has been.

Ｆ：特定周波数、Ｃ：音速、Ｓ：開放用孔部１５５の開口面積（πＲａ２）、Ｖ：第１閉空間１５１の容積、Ｌ：開放用孔部１５５の長さ寸法
上記ヘルムホルツの数式を見ても分かるように、開放用孔部１５５の開口面積、すなわち開放用孔部１５５の孔径Ｒａを小さくすることにより、特定周波数を低くすることができる。本パチンコ機１０では、当該特定周波数を所定の低音域に設定するために、開放用孔部１５５の孔径Ｒａは第１スピーカ装置６３の前面側の口径Ｒｂよりも小さくなるように設定されている。なお、本パチンコ機１０では、開放用孔部１５５の長さ寸法Ｌが後壁部１１３の厚み寸法及び遊技盤２３の厚み寸法により規定されているため、開放用孔部１５５の孔径Ｒａを調整することで、特定周波数を調整しているが、例えば、後壁部１１３の前面や遊技盤２３の背面などに開放用孔部１５５の長さ寸法を延長させるための延長部材を設け、かかる延長部材の長さ寸法を調整することで、特定周波数を調整してもよい。

F: specific frequency, C: speed of sound, S: opening area of opening hole 155 (πRa2), V: volume of first closed space 151, L: length of opening hole 155 See the above Helmholtz equation As can be seen, the specific frequency can be lowered by reducing the opening area of the opening hole 155, that is, the hole diameter Ra of the opening hole 155. In the pachinko machine 10, the hole diameter Ra of the opening hole 155 is set to be smaller than the diameter Rb on the front side of the first speaker device 63 in order to set the specific frequency in a predetermined low frequency range. . In this pachinko machine 10, since the length L of the opening hole 155 is defined by the thickness of the rear wall 113 and the thickness of the game board 23, the hole diameter Ra of the opening hole 155 is adjusted. However, for example, an extension member for extending the length of the opening hole 155 is provided on the front surface of the rear wall 113, the back surface of the game board 23, or the like. The specific frequency may be adjusted by adjusting the length dimension of the member.

  As the opening hole 155 functions as a bass reflex port, the sound output from the back side of the first speaker device 63 and having a specific frequency resonates in the opening hole 155 and the phase is inverted. In the state, that is, in the state of being in phase with the sound output from the front side of the first speaker device 63, it is radiated to the rear of the gaming machine base unit 13. The radiated sound is transmitted to the front of the pachinko machine 10 through a gap between the gaming machine base unit 13 and the outer frame 11, and the sound of a specific frequency set as a low frequency range is enhanced. Thereby, the sound quality in the low sound range is improved.

  Incidentally, the first speaker device 63 is electrically connected to an audio lamp control device 82 provided on the back surface of the game board 23, and a sound is generated according to a drive signal output from the audio lamp control device 82. Is output. In this case, as shown by a two-dot chain line in FIG. 5, the opening hole 155 is also used as a through hole for passing the signal line 156 for transmitting the drive signal before and after the gaming machine base unit 13. May be. In addition, other electrical components provided on the gaming machine front unit 14 such as an LED board, and a control device provided on the back side of the gaming machine base unit 13 such as an audio lamp control device 82 or on the rear side of the gaming machine base unit 13. An opening hole 155 may also be used as a through hole for a signal line for electrically connecting the two.

  As described above, the sound output from the back side of the first speaker device 63 to the first closed space 151 is transmitted to the front of the pachinko machine 10 through the opening hole 155, but other sounds in the first closed space 151 are also transmitted. In some places, the sealing is enhanced. That is, as already described, an overlap region is formed in the outer peripheral portion of the pachinko machine 10 by the front edge frame portion 112 and the rear edge frame portion 114, and a rubber packing 117 is provided for the overlap region. In addition, an overlapping region is formed between the peripheral portion 121 of the window hole 22 and the window panel unit 53, and a rubber packing 123 is provided for the overlapping region. Thereby, the airtightness of the 1st closed space 151 is improved. The improvement in the sealing performance is that the overlap in the front-rear direction between the partition walls 133 and 134 formed on the front wall portion 111 and the partition walls 143 and 144 formed on the rear wall portion 113 is a surface contact over a predetermined range. It is also planned by what is done. Since the airtightness is improved as described above, the sound output from the front side of the first speaker device 63 except the sound having a frequency less than the specific frequency transmitted through the opening hole 155, and the first speaker device 63. The sound output from the back side of the sound is suppressed from canceling out, and the sound quality is improved. By the way, the sound output from the back side of the first speaker device 63 with respect to the game ball flowing down the game area due to the enhanced sealing performance between the peripheral portion 121 of the window hole 22 and the window panel unit 53. There is also an effect that the influence of is reduced.

  As shown in FIGS. 5 and 7, a sound absorbing material 157 is provided as a sound absorbing means on the front surface of the region defining the first closed space 151 in the rear wall portion 113. In this pachinko machine 10, felt is used as the sound absorbing material 157, but the present invention is not limited to this, and glass wool, polyurethane, a general-purpose rubber plate, or the like may be used. The sound absorbing material 157 has a lower hardness than other regions that partition the first closed space 151. The sound absorbing material 157 is attached to the front surface of the rear wall 113 so as not to block the opening hole 155. By providing the sound absorbing material 157, the output level of the sound output from the back side of the first speaker device 63 is moderately suppressed, and sound chatter based on resonance in the first closed space 151 or the like. Can be reduced. Thereby, high sound quality is achieved. In FIG. 2, the sound absorbing material 157 is omitted for convenience of explanation.

  On the other hand, a reinforcing metal plate 158 is fixed to the back surface of the area defining the first closed space 151 in the front wall portion 111 in order to increase the strength in the surface direction of the base frame 51, and the sound absorbing material 157 is provided. Not. In FIG. 2, the reinforcing metal plate 158 is omitted for convenience of explanation.

  Although the structure which provides the sound-absorbing material 157 in both the front surface of the area | region which divides the 1st closed space 151 in the rear wall part 113 and the back surface of the area | region which divides the 1st closed space 151 in the front wall part 111 is also considered, in this case, As a result, the volume of the first closed space 151 is restricted, which is not preferable. In addition, since the area that divides the side portion of the first closed space 151 has a boundary that is separated when the gaming machine front unit 14 is opened, if the sound absorbing material 157 is provided at the boundary, the gaming machine front unit 14 has a boundary. The sound absorbing material 157 may be caught during the opening / closing operation, which is not preferable. Furthermore, a configuration in which the reinforcing metal plate 158 is provided on the front surface of the front wall portion 111 instead of the back surface and the sound absorbing material 157 is provided on the back surface of the front wall portion 111 is also conceivable. As described above, since the LED substrates 61 and 62, the upper plate unit 71, and the lower plate unit 72 are provided, there is no space, and it is not preferable to provide the reinforcing metal plate 158 on the front surface side of the front wall portion 111. Therefore, in order to suitably suppress both chatter noise and improve the strength in the surface direction of the base frame 51, the sound absorbing material 157 is provided on the front surface of the region defining the first closed space 151 in the rear wall 113. In addition, it is preferable that the reinforcing metal plate 158 is provided on the back surface of the region defining the first closed space 151 in the front wall portion 111.

  Incidentally, in order to increase the strength of the resin base 21 in the surface direction, a reinforcing metal plate 159 may be provided on the back side of the rear wall 113 as shown by a two-dot chain line in FIG.

  The power source and launch control board 172 includes a power source unit and a launch control unit. The power supply unit supplies necessary operating power to the main control circuit 162, the payout control board 171 and the like through a path indicated by a double line arrow. The launch control unit is responsible for launch control of the game ball launch mechanism 43 according to the operation of the launch handle 44 by the player, and the game ball launch mechanism 43 is driven when predetermined launch conditions are met.

  The sound lamp control board 174 controls the LED boards 61 and 62, the speaker devices 63 and 64, and the display control device 178 based on the effect command transmitted from the MPU 164 of the main control circuit 162. The MPU 181 that is an arithmetic unit includes a ROM 182 that stores a control program executed by the MPU 181, fixed value data, and the like, and a RAM 183 that is used as a work memory or the like. Note that the present invention is not limited to a configuration in which an effect is performed through sound output from the speaker devices 63 and 64. When a predetermined abnormal state is specified by the MPU 164 of the main control circuit 162, the notification is performed. Therefore, a configuration may be adopted in which sound is output from the speaker devices 63 and 64. Further, the symbol display device 32 is controlled to be displayed through the display control device 178.

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

  In a state where the gaming machine front unit 14 is disposed at the closed position, closed spaces 151 and 152 are defined by the base frame 51 of the gaming machine front unit 14 and the resin base 21 of the gaming machine base unit 13, and the speaker device 63, Sound is output from the rear side of 64 to the closed spaces 151 and 152. Thereby, cancellation of the sound output from the front side of the speaker devices 63 and 64 and the sound output from the back side is unlikely to occur, and high sound quality is achieved. In particular, in this configuration, since the closed spaces 151 and 152 are formed using the gaming machine front unit 14 and the gaming machine base unit 13, the gaming machine front unit 14 is formed to form the closed spaces 151 and 152. And it is not necessary to provide a member different from the gaming machine base unit 13. Therefore, the above effects can be achieved while effectively utilizing the space on the back side of the gaming machine front unit 14 and the front side of the gaming machine base unit 13. Furthermore, since the closed space 151, 152 can be opened forward of the pachinko machine 10 by arranging the gaming machine front unit 14 in the open position, maintenance of the closed space 151, 152 and maintenance of the speaker devices 63, 64 are possible. Can be performed satisfactorily.

  Further, in the configuration in which sound is output from the back side of the speaker devices 63 and 64 to the closed spaces 151 and 152, the diaphragms 103 and 104 of the speaker devices 63 and 64 depend on the viscosity of the air surrounded by the closed spaces 151 and 152. The vibration is easily suppressed. In this case, an opening hole 155 is formed in a region defining the closed spaces 151 and 152 in the rear wall portion 113 of the resin base 21, and the closed spaces 151 and 152 are opened to the outside. The vibrations of the diaphragms 103 and 104 of the devices 63 and 64 are hardly suppressed. Further, in the configuration in which the opening hole is formed in the area defining the closed spaces 151 and 152 in the front wall portion 111 of the base frame 51, the gaming machine base unit 13 from the front of the pachinko machine 10 through the opening hole. However, since the opening hole 155 is formed in the rear wall 113 as described above, the opening hole 155 is suppressed while suppressing the occurrence of such inconvenience. Can be provided.

  Furthermore, the opening hole 155 functions as a bass reflex port for enhancing the sound of a specific frequency set in the low sound range, and the sound radiated from the opening hole 155 is separated from the gaming machine base unit 13 and the outer frame. 11 is transmitted to the front of the pachinko machine 10 through a gap between the two and the like, and the sound of the specific frequency is enhanced. Thereby, the sound quality in the low sound range is improved.

  In the case where the speaker devices 63 and 64 are provided in the gaming machine front unit 14, the gaming machine front unit from the front of the pachinko machine 10 can be obtained by opening holes in the speaker devices 63 and 64 or removing the speaker devices 63 and 64. An act of illegally forming a passage leading to the rear of 14 and inserting a fraudulent jig into the rear of the gaming machine front unit 14 through the passage is assumed. In the configuration in which the opening hole 155 is formed in the rear wall 113 as described above, the act of causing the fraud jig to further enter the back side of the gaming machine base unit 13 through the opening hole 155. Is assumed. On the other hand, the opening hole 155 is formed at a position where the central axis extending in the hole length direction of the opening hole 155 is not collinear with the central axis extending in the thickness direction of the speaker devices 63 and 64. Even if the fraudulent jig is inserted linearly from the position of the speaker devices 63 and 64, it is difficult to enter the opening hole 155. Therefore, it is possible to suppress the injustice jig from entering the back side of the gaming machine base unit 13.

  In particular, the opening hole 155 is formed at a position outside the region behind the pachinko machine 10 of the speaker devices 63 and 64 when the gaming machine front unit 14 is disposed at the closed position on the rear wall 113. Therefore, even if the fraudulent jig is inserted from the position of the speaker devices 63 and 64, the fraudulent jig is bent to move the distal end side of the fraudulent jig to the position of the opening hole 155. It is necessary to bring it, and it becomes difficult for the fraudulent jig to enter the opening hole 155. Therefore, it is possible to suppress the injustice jig from entering the back side of the gaming machine base unit 13.

  The opening hole 155 is formed such that the area of the cross section in the direction orthogonal to the hole length direction is smaller than the area on the front side of the speaker devices 63 and 64. Also from this point, even if the fraud jig is inserted from the position of the speaker devices 63 and 64, the fraud jig does not easily enter the opening hole 155, and the fraud jig is not connected to the gaming machine base unit. 13 can be prevented from entering the back side.

  Further, the opening hole 155 is located at a position spaced inside the closed space 151, 152 with respect to the region constituting the peripheral surface of the closed space 151, 152 between the front wall portion 111 and the rear wall portion 113. Is formed. As a result, the tip side of the fraud jig inserted from the position of the speaker devices 63 and 64 is made to follow the peripheral surface of the closed spaces 151 and 152 to bring the tip side to the position of the opening hole 155. Even it becomes difficult to do.

  In order to effectively utilize the space on the front side of the gaming machine base unit 13, the gaming area and the closed spaces 151, 152 are adjacent to each other, and are attached to the window hole 22 and the base frame 51 formed in the resin base 21. The game area and the closed spaces 151 and 152 are partitioned by the overlapping area of the window panel unit 53. This makes it difficult for vibration due to sound output from the back side of the speaker devices 63 and 64 to be transmitted to the air in the game area, and sound output from the back side of the speaker device 63 and 64 to the game ball flowing down the game area. Can be reduced.

  The partition structure is formed by the panel frame body 54 of the window panel unit 53 entering the inside of the peripheral edge 121 of the window hole 22 and the peripheral edge 121 and the panel frame 54 overlapping inside and outside. Thereby, even if the fraud jig is inserted from the boundary between the gaming machine front unit 14 and the gaming machine base unit 13, the fraud jig can be prevented from entering the gaming area. At the same time, due to the enhanced sealing performance from the closed spaces 151 and 152 to the game area side, vibration due to sound output from the back side of the speaker devices 63 and 64 to the closed spaces 151 and 152 causes air in the game area. It becomes difficult to be transmitted to.

  Further, the partition structure is formed by using the window hole 22 and the window panel unit 53 that make the game area visible from the front of the pachinko machine 10. In other words, the above-described excellent effect resulting from the partition structure can be achieved while simplifying the configuration by forming the partition structure using a configuration necessary for making the gaming area visible in the pachinko machine 10. Can play.

  By providing the sound absorbing material 157 as a hardness reduction region on the peripheral surfaces that define the closed spaces 151 and 152, the output level of the sound output from the back side of the speaker devices 63 and 64 is moderately suppressed, Sound chatter based on resonance in the closed spaces 151 and 152 can be reduced. Thereby, high sound quality is achieved.

<Second Embodiment>
In the first embodiment, the opening hole 155 is formed with respect to the rear wall portion 113 constituting the resin base 21 of the gaming machine base unit 13, but in the present embodiment, it is a game.

Further, the configuration different from the first embodiment will be described, and the description of the same configuration as the first embodiment will be basically omitted.

  As shown in FIG. 9, a through hole 191 having a circular cross-section in the front-rear direction is formed in a region defining the first closed space 151 in the front wall portion 111, and the region where the through hole 191 is formed A port forming member 192 is attached. The port forming member 192 includes a cylindrical portion 194 in which a cylindrical hole 193 having the same diameter as that of the through hole 191 is formed, and the cylindrical portion 194 extends outward from one opening side end of the cylindrical hole 193. A flange portion 195 formed so as to protrude is integrally formed.

  The port forming member 192 has a rear surface of the front wall portion 111 such that the cylindrical hole 193 is positioned on the same axis as the through hole 191 and the flange portion 195 overlaps the peripheral edge portion of the through hole 191 on the rear surface of the front wall portion 111. It arrange | positions in the side and is screwed from the back side of the front wall part 111 in the state. As a result, the first closed space 151 has an opening hole as a bass reflex port for radiating the sound output to the first closed space 151 from the back side of the first speaker device 63 toward the front of the pachinko machine 10. 196 is provided.

  The length dimension and the hole diameter of the opening hole 196 are set so as to resonate a sound having a specific frequency in the low sound range. In addition, a front cover 65 is provided in front of the pachinko machine 10 in the opening hole 196, and a plurality of slits are provided as bass reflex port side discharge holes in a region facing the opening hole 196 in the front cover 65. 197 is formed.

That is, the sound is emitted in front of the gaming machine front unit 14 in the same phase as the sound output from the front side of the first speaker device 63. Thereby, the sound quality in the low sound range is improved. In particular, according to this configuration, the sound of a specific frequency resonated in the opening hole 196 is radiated from the opening hole 196 toward the front of the pachinko machine 10, and thus the sound is easily transmitted to the player. Become.

<Third Embodiment>
In the first embodiment, the opening hole 155 is formed with respect to the rear wall 113 constituting the resin base 21 of the gaming machine base unit 13, but in the present embodiment, the opening hole 155 is formed. The hole 155 is not formed, and instead, the function of the opening hole 155 is shared by a passage for guiding the game ball to a predetermined area. This configuration will be described with reference to FIGS. FIG. 10 is a front view of the pachinko machine 10 for explaining the region of the first closed space 201 in the present embodiment, and FIG. 11 shows the pachinko machine 10 showing the configuration of the first closed space 201 and its peripheral part. FIG. In FIG. 11, the configuration of the back side of the gaming machine base unit 13 and the gaming board 23 is omitted for convenience of explanation. Further, the configuration different from the first embodiment will be described, and the description of the same configuration as the first embodiment will be basically omitted.

  As shown in FIG. 10, the first closed space 201 covers the window panel unit over the region from the upper side of the window panel unit 53 to the lower side of the window panel unit 53 on the rotating front end side of the gaming machine body 12. It is formed so as to bypass 53. In this case, the lower side of the first closed space 201 is partitioned by a region in which the partition wall 202 provided in the gaming machine front unit 14 and the partition wall 203 provided in the gaming machine base unit 13 are vertically overlapped.
