That is, by connecting the first connection reinforcing metal fitting 111 and the second connection reinforcing metal fitting 115 to the left frame member 37 and the curtain plate 44, the deformation of the left frame member 37 is restricted, and the outer The rigidity of the frame 11 can be improved.
同様に、前記外枠11の下枠部材40および右枠部材38は、第3の下連結金具120により連結固定される。この第2の下連結金具120は、断面L字状に形成された第4の連結補強金具125の支持板部127が断面コ字状に形成された第3の連結補強金具121における上下の対向板部122,123の間に臨むよう構成される。このため、外枠11に対して横方向の力が作用して右枠部材38が開口内側に倒れ込むよう変形しようとした場合には、前記第3の連結補強金具121の上側対向板部122が第4の連結補強金具125の支持板部127に接触し、該右枠部材38の変形が阻止される。また、前記第2の下連結金具120では、前記第3の連結補強金具121における前記上側対向板部122が前記下枠部材40における幕板44の右端部側に連結されると共に、下側対向板部123が下枠部材40における右側の第1固定部42に連結され、更に連結板部124が右枠部材38に連結されている。そして、前記第4の連結補強金具125は、重合板部126が前記第3の連結補強金具121の連結板部124に重なるよう右枠部材38に連結されると共に、前記支持板部127が前記幕板44における右側の第2固定部45に連結される。従って、前記右枠部材38が開口内側に倒れ込むよう変形する場合には、前記第3の連結補強金具121の上側対向板部122が左側に移動しようとするのに対して、該上側対向板部122が連結される幕板44は、前記第4の連結補強金具125にも連結されているため、該第4の連結補強金具125により幕板44の移動が規制される。すなわち、前記第3の連結補強金具121および第4の連結補強金具125の夫々を前記右枠部材38および幕板44に連結することで、該右枠部材38の変形が規制され、外枠11の剛性の向上が図られる。
Similarly, the lower frame member 40 and the right frame member 38 of the outer frame 11 are connected and fixed by a third lower connection fitting 120. The second lower connection fitting 120 is vertically opposed to the third connection reinforcement fitting 121 in which the support plate portion 127 of the fourth connection reinforcement fitting 125 formed in an L shape in cross section is formed in a U shape in cross section. It is comprised so that it may face between the board parts 122 and 123. FIG. For this reason, when a lateral force acts on the outer frame 11 and the right frame member 38 tries to be deformed to fall inside the opening, the upper opposing plate portion 122 of the third connection reinforcing metal member 121 The contact with the support plate portion 127 of the fourth connection reinforcing metal fitting 125 is prevented from deforming the right frame member 38. In the second lower connection fitting 120, the upper facing plate portion 122 in the third connection reinforcing fitting 121 is connected to the right end portion side of the curtain plate 44 in the lower frame member 40, and the lower facing portion is connected. The plate portion 123 is connected to the first fixing portion 42 on the right side of the lower frame member 40, and the connecting plate portion 124 is further connected to the right frame member 38. The fourth connection reinforcing bracket 125 is connected to the right frame member 38 so that the overlapping plate portion 126 overlaps the connection plate portion 124 of the third connection reinforcing bracket 121, and the support plate portion 127 is It is connected to the right second fixing portion 45 of the curtain plate 44. Therefore, when the right frame member 38 is deformed so as to fall into the inside of the opening, the upper facing plate portion 122 of the third connection reinforcing bracket 121 tends to move to the left side, whereas the upper facing plate portion Since the curtain plate 44 to which 122 is coupled is also coupled to the fourth coupling reinforcement fitting 125, the movement of the curtain plate 44 is restricted by the fourth coupling reinforcement bracket 125. That is, by connecting the third connection reinforcing metal fitting 121 and the fourth connection reinforcing metal fitting 125 to the right frame member 38 and the curtain plate 44, the deformation of the right frame member 38 is restricted, and the outer frame 11 The rigidity of the can be improved.

That is, the lower frame member 40 and the left frame member 37 are connected and fixed by the first lower connection fitting 110, and the lower frame member 40 and the right frame member 38 are connected and fixed by the second lower connection fitting 120, The connecting portion of the lower frame member 40 and the left frame member 37 and the connecting portion of the lower frame member 40 and the right frame member 38 are prevented from being deformed, and the rigidity of the entire outer frame 11 is improved.
そして、前記第1の下連結金具110の上側対向板部112には、中枠12の下端部(下支持金具23)を軸支する下支軸110aが形成されており、該中枠12を開放した状態では、中枠12だけでなく、該中枠12に配設された遊技盤13や前枠14、上下の球皿15,16、その他の部材の重量が全て第1の下連結金具110の上側対向板部112に集中する。この場合も、中枠12を支持する第1の連結補強金具111の上側対向板部112が第2の連結補強金具115の支持板部117で支持されるから、該上側対向板部112の変形等を招来することなく、中枠12を支持することができる。また、第1の連結補強金具111の上側対向板部112が第2の連結補強金具115の支持板部117で支持されることで、該上側対向板部112が当接する前記下枠部材40の幕板44(設置部46)に過大な負荷が掛かるのを防止でき、該幕板44(設置部46)が損傷するのを防止できる。
A lower support shaft 110a that pivotally supports a lower end portion (lower support metal fitting 23) of the middle frame 12 is formed on the upper facing plate portion 112 of the first lower connection fitting 110. In the opened state, not only the inner frame 12, but also the game board 13, the front frame 14, the upper and lower ball trays 15 and 16, and other members arranged on the inner frame 12 are all the first lower connecting brackets. It concentrates on the upper opposing plate part 112 of 110. FIG. Also in this case, since the upper opposing plate portion 112 of the first connection reinforcing metal fitting 111 that supports the middle frame 12 is supported by the support plate portion 117 of the second connection reinforcing metal fitting 115, the upper opposing plate portion 112 is deformed. The middle frame 12 can be supported without inviting etc. Further, the upper opposing plate portion 112 of the first connection reinforcing metal fitting 111 is supported by the support plate portion 117 of the second connection reinforcing metal fitting 115, so that the lower frame member 40 with which the upper opposing plate portion 112 abuts is supported. It is possible to prevent an excessive load from being applied to the curtain plate 44 (installation portion 46) and to prevent the curtain plate 44 (installation portion 46) from being damaged.
また、前記中枠12を閉成した状態では、該中枠12が幕板44(第2の傾斜案内部材56および支持リブ65)に支持され、中枠12に配設された遊技盤13等を含む重量が幕板44の上面49に集中する。実施例では、前記第2の下連結金具120における第3の連結補強金具121の上側対向板部122が幕板44の上面49の裏側に当接するから、該幕板44(第2の傾斜案内部材56および支持リブ65)に掛かる荷重を上側対向板部122で支持でき、該幕板44の変形等を招来することなく確実に中枠12を支持することができる。
When the middle frame 12 is closed, the middle frame 12 is supported by the curtain plate 44 (second inclined guide member 56 and support rib 65), and the game board 13 disposed on the middle frame 12 or the like. Is concentrated on the upper surface 49 of the curtain plate 44. In the embodiment, the upper facing plate portion 122 of the third connection reinforcing metal member 121 in the second lower connection metal member 120 abuts on the back side of the upper surface 49 of the screen plate 44, so that the screen plate 44 (second inclined guide). The load applied to the member 56 and the support rib 65) can be supported by the upper facing plate portion 122, and the middle frame 12 can be reliably supported without causing deformation of the curtain plate 44 or the like.
また、第1の下連結金具110における第1の連結補強金具111の連結板部114と、第2の連結補強金具115における重合板部116とを重ね合わせた状態で前記左枠部材37に一体的に連結するようにしたことにより、両補強金具111,115の一体性が向上し、補強効果の向上を期待できる。更に、前記第1の連結補強金具111における連結板部114に溝部114aを形成して、前記左枠部材37に形成した膨出部39と整合させるようにしたことで、該左枠部材37に対して第1の連結補強金具111が前後方向に位置ずれするのを防止でき、位置ずれによる補強効果の低下を防ぐことができる。また、第1の連結補強金具111と第2の連結補強金具115とを組み付けた際には、該第1の連結補強金具111の連結板部114に形成した位置決め突部114cが第2の連結補強金具115の重合板部116に形成した位置決め孔116bに挿入されるようにしたことにより、第1の連結補強金具111と第2の連結補強金具115とを位置決めすることができ、両補強金具111,115の位置ずれによる補強効果の低下を防止し得る。また、前記位置決め突部114cおよび位置決め孔116bにより、前記第1の連結補強金具111および第2の連結補強金具115が誤った状態で組み付けられるのを防止できる。
In addition, the connecting plate portion 114 of the first connecting reinforcing metal fitting 111 in the first lower connecting metal fitting 110 and the overlapping plate portion 116 in the second connecting reinforcing metal fitting 115 are overlapped with the left frame member 37 in an integrated state. As a result of the connection, the integrity of the two reinforcing metal fittings 111 and 115 is improved, and an improvement in the reinforcing effect can be expected. Further, a groove 114a is formed in the connecting plate portion 114 of the first connecting reinforcing metal fitting 111 so as to be aligned with the bulging portion 39 formed in the left frame member 37. On the other hand, it is possible to prevent the first connection reinforcing metal fitting 111 from being displaced in the front-rear direction, and to prevent a reduction in the reinforcing effect due to the displacement. Further, when the first connection reinforcing metal fitting 111 and the second connection reinforcing metal fitting 115 are assembled, the positioning protrusion 114c formed on the connection plate portion 114 of the first connection reinforcing metal fitting 111 is the second connection reinforcing metal fitting 111. By being inserted into the positioning hole 116b formed in the overlapping plate portion 116 of the reinforcing bracket 115, the first connecting reinforcing bracket 111 and the second connecting reinforcing bracket 115 can be positioned, and both the reinforcing brackets can be positioned. It is possible to prevent a reduction in the reinforcing effect due to the positional deviation of 111,115. Further, the positioning protrusion 114c and the positioning hole 116b can prevent the first connection reinforcing metal fitting 111 and the second connection reinforcing metal fitting 115 from being assembled in an erroneous state.
そして、第2の下連結金具120についても前述した第1の下連結金具110の関係が成立する。すなわち、前記第2の下連結金具120における第3の連結補強金具121の連結板部124と、第4の連結補強金具125における重合板部126とを重ね合わせた状態で前記右枠部材38に一体的に連結するようにしたことにより、両補強金具121,125の一体性が向上し、補強効果の向上を期待できる。更に、前記第3の連結補強金具121における連結板部124に溝部124aを形成して、前記右枠部材38に形成した膨出部39と整合させるようにしたことで、該右枠部材38に対して第3の連結補強金具121が前後方向に位置ずれするのを防止でき、位置ずれによる補強効果の低下を防ぐことができる。また、第3の連結補強金具121と第4の連結補強金具125とを組み付けた際には、該第3の連結補強金具121の連結板部124に形成した位置決め突部124cが第4の連結補強金具125の重合板部126に形成した位置決め孔126bに挿入されるようにしたことにより、第3の連結補強金具121と第4の連結補強金具125とを位置決めすることができ、両補強金具121,125の位置ずれによる補強効果の低下を防止し得る。また、前記位置決め突部124cおよび位置決め孔126bにより、前記第3の連結補強金具121および第4の連結補強金具125が誤った状態で組み付けられるのを防止できる。
And the relationship of the 1st lower connection metal fitting 110 mentioned above is materialized also about the 2nd lower connection metal fitting 120. FIG. That is, the right frame member 38 is overlapped with the connecting plate portion 124 of the third connecting reinforcing metal member 121 in the second lower connecting metal member 120 and the overlapping plate portion 126 in the fourth connecting reinforcing metal member 125. By connecting them integrally, the integrity of the two reinforcing metal members 121 and 125 is improved, and an improvement in the reinforcing effect can be expected. Further, a groove portion 124a is formed in the connection plate portion 124 of the third connection reinforcing metal fitting 121 so as to be aligned with the bulging portion 39 formed in the right frame member 38. On the other hand, it is possible to prevent the third connecting reinforcing metal member 121 from being displaced in the front-rear direction, and to prevent a reduction in the reinforcing effect due to the displacement. Further, when the third connection reinforcing metal fitting 121 and the fourth connection reinforcing metal fitting 125 are assembled, the positioning protrusion 124c formed on the connection plate portion 124 of the third connection reinforcing metal fitting 121 is the fourth connection reinforcing metal fitting 121. By being inserted into the positioning hole 126b formed in the overlapping plate portion 126 of the reinforcing metal fitting 125, the third connecting reinforcing metal 121 and the fourth connecting reinforcing metal 125 can be positioned, and both reinforcing metal fittings can be positioned. It is possible to prevent a reduction in the reinforcing effect due to the positional deviation of 121,125. Further, the positioning protrusions 124c and the positioning holes 126b can prevent the third connection reinforcing metal member 121 and the fourth connection reinforcing metal member 125 from being assembled in an incorrect state.
また、前記中枠12を枢支する上支持金具22における第1軸孔22aと第1の上連結金具100における上支軸100aとの遊びや、下支持金具23における第2軸孔23aと第1の下連結金具110における下支軸110aとの遊び等に起因して、中枠12の開放時に、中枠12の重量により開放端側が垂れ下がる。そこで、実施例に係るパチンコ機10では、前記外枠11における下枠部材40(幕板44)の第1の下連結金具110側(左枠部材37側)に、第1の傾斜案内部材50を配設すると共に、該下枠部材40(幕板44)の右端部側(右枠部材38側)に、第2の傾斜案内部材56を配設し、更に該下枠部材40(幕板44)における第1の傾斜案内部材50と第2の傾斜案内部材56との間に支持リブ65を設けて、中枠12を閉成するに際し、該中枠12の下端部を持ち上げるようにしたから、中枠12の開放端側の垂れ下がりが矯正され、下枠部材40(幕板44)に中枠12が接触するのを防止できる。
Further, the play between the first shaft hole 22a in the upper support fitting 22 that pivotally supports the middle frame 12 and the upper support shaft 100a in the first upper connection fitting 100, the second shaft hole 23a in the lower support fitting 23, and the second Due to the play with the lower support shaft 110 a in the lower connection fitting 110, the open end side hangs down due to the weight of the middle frame 12 when the middle frame 12 is opened. Therefore, in the pachinko machine 10 according to the embodiment, the first inclined guide member 50 is provided on the first lower connecting bracket 110 side (left frame member 37 side) of the lower frame member 40 (screen plate 44) in the outer frame 11. , A second inclined guide member 56 is disposed on the right end side (right frame member 38 side) of the lower frame member 40 (screen plate 44), and the lower frame member 40 (screen plate) is further disposed. 44), a support rib 65 is provided between the first inclined guide member 50 and the second inclined guide member 56 so that the lower end portion of the intermediate frame 12 is lifted when the intermediate frame 12 is closed. Thus, the sag of the open end side of the middle frame 12 is corrected, and the middle frame 12 can be prevented from contacting the lower frame member 40 (curtain plate 44).
具体的には、中枠12を閉成する過程において、中枠12における下支持金具23側の下端部が前記第1の傾斜案内部材50の第1の傾斜面部52aに乗り上げて持ち上げられ、この状態で更に中枠12を閉成させると、中枠12における下支持金具23側より右側の下端部が前記支持リブ65の第3の傾斜面部66に乗り上げて持ち上げられる。更に中枠12の閉成を続けると、中枠12の開放端側の下端部が前記第2の傾斜案内部材56の第2の傾斜面部60に乗り上げて持ち上げられる。すなわち、中枠12を閉成する際に、中枠12における下支持金具23側の下端部から開放端側の下端部に亘る全体が持ち上げられることで中枠12の傾きが矯正され、中枠12が下枠部材40(幕板44)の前面に接触するのは防止される。
Specifically, in the process of closing the middle frame 12, the lower end of the middle frame 12 on the lower support fitting 23 side rides on the first inclined surface portion 52a of the first inclined guide member 50 and is lifted. When the middle frame 12 is further closed in this state, the lower end portion on the right side of the middle frame 12 from the lower support fitting 23 side rides on the third inclined surface portion 66 of the support rib 65 and is lifted. When the closing of the middle frame 12 is further continued, the lower end portion on the open end side of the middle frame 12 rides on the second inclined surface portion 60 of the second inclined guide member 56 and is lifted. That is, when the middle frame 12 is closed, the whole frame 12 is lifted up from the lower end on the lower support fitting 23 side to the lower end on the open end side, so that the inclination of the middle frame 12 is corrected. 12 is prevented from contacting the front surface of the lower frame member 40 (curtain plate 44).
そして、図17〜図20に示すように、前記下枠部材40における幕板44の左右に離間する位置に前記第1の傾斜案内部材50(第1の傾斜面部52a)、第2の傾斜案内部材56(第2の傾斜面部60)および支持リブ65(第3の傾斜面部66)を設けたことにより、前記中枠12を閉成する過程において、中枠12の下端部が最初に第1の傾斜面部52aに接触して乗り上げ、該第1の傾斜面部52aに乗り上げる途中で中枠12の下端部が第3の傾斜面部66に接触して乗り上げると共に、第3の傾斜面部66に乗り上げる途中で中枠12の下端部が第2の傾斜面部60に接触して乗り上げることになる。このように、中枠12を閉成する過程で、中枠12の下端部を第1〜第3の傾斜面部52a,60,66で徐々に持ち上げることにより、中枠12の閉成動作を円滑に行ない得ると共に、第1〜第3の傾斜面部52a,60,66の夫々に掛かる荷重を分散でき、中枠12の開閉に対する耐久性の向上を図り得る。また、中枠12を完全に閉成した状態では、第2の傾斜案内部材56および支持リブ65に設けた支持面部62,67に中枠12の下端部が当接するから、該中枠12の荷重を分散して支持することができる。
As shown in FIGS. 17 to 20, the first inclined guide member 50 (first inclined surface portion 52 a) and the second inclined guide are arranged at positions separated from the left and right of the curtain plate 44 in the lower frame member 40. By providing the member 56 (second inclined surface portion 60) and the support rib 65 (third inclined surface portion 66), in the process of closing the middle frame 12, the lower end portion of the middle frame 12 is first the first. The lower end portion of the middle frame 12 contacts the third inclined surface portion 66 and rides on the third inclined surface portion 66 while riding on the first inclined surface portion 52a. Thus, the lower end portion of the middle frame 12 comes into contact with the second inclined surface portion 60 and rides up. Thus, in the process of closing the middle frame 12, the lower end portion of the middle frame 12 is gradually lifted by the first to third inclined surface portions 52a, 60, 66, thereby smoothly closing the middle frame 12. In addition, the load applied to each of the first to third inclined surface portions 52a, 60, 66 can be dispersed, and the durability against opening and closing of the middle frame 12 can be improved. Further, in a state where the middle frame 12 is completely closed, the lower end portion of the middle frame 12 abuts on the support surface portions 62 and 67 provided on the second inclined guide member 56 and the support rib 65. The load can be dispersed and supported.
ここで、前記第1の傾斜案内部材50は、前記中枠12を枢支する第1の下連結金具110に最も近接する位置に設けられており、閉成した中枠12が前記第1の傾斜案内部材50(第1の傾斜面部52a)に接触した際に、該中枠12と下枠部材40(幕板44)との交差角度が大きくなる。このため、前記第1の傾斜案内部材50における第1の傾斜面部52aを前端部から後方へ向けて一様に上方傾斜させた場合には、中枠12の閉成時に、第1の傾斜面部52aの左端部にのみ中枠12(下支持金具23)が接触し、当該第1の傾斜面部52aに傷や削れが生ずる原因ともなる。そこで、実施例では、閉成した中枠12が前記第1の傾斜案内部材50(第1の傾斜面部52a)に接触した際に、該第1の傾斜面部52aと中枠12における下支持金具23の接触部位とが平行になるよう構成してあるから(図18参照)、中枠12の下支持金具23を第1の傾斜面部52aの全体で支持でき、当該第1の傾斜面部52aへの傷や削れが生ずるのを防止しつつ、中枠12を円滑に持ち上げることができる。
Here, the first inclined guide member 50 is provided at a position closest to the first lower connecting fitting 110 that pivotally supports the middle frame 12, and the closed middle frame 12 is the first When contacting the inclined guide member 50 (first inclined surface portion 52a), the crossing angle between the middle frame 12 and the lower frame member 40 (curtain plate 44) becomes large. For this reason, when the first inclined surface portion 52a of the first inclined guide member 50 is uniformly inclined upward from the front end portion to the rear, the first inclined surface portion is closed when the middle frame 12 is closed. The middle frame 12 (lower support fitting 23) is in contact with only the left end portion of 52a, which may cause damage and scraping to the first inclined surface portion 52a. Therefore, in the embodiment, when the closed middle frame 12 comes into contact with the first inclined guide member 50 (first inclined surface portion 52a), the first inclined surface portion 52a and the lower support metal fitting on the inner frame 12 are used. 23, the lower support fitting 23 of the middle frame 12 can be supported by the entirety of the first inclined surface portion 52a, and the first inclined surface portion 52a can be supported. The middle frame 12 can be smoothly lifted while preventing the occurrence of scratches and scraping.
前記第1の傾斜案内部材50は、前記下枠部材40の幕板44に形成した設置部46の第1設置凹部47に配置されて、該第1設置凹部47に第1の傾斜案内部材50を設置した状態で、前記第1の下連結金具110の上側対向板部112に形成した通孔112aおよび第1の傾斜案内部材50に形成した通孔54に挿通したネジを、設置部46(第1設置凹部47)のネジ孔47aに螺挿して固定される。すなわち、第1の下連結金具110を下枠部材40(幕板44)に連結するのに併せて第1の傾斜案内部材50を固定できるから、該第1の傾斜案内部材50を容易に取り付けることができる。
The first inclined guide member 50 is disposed in a first installation recess 47 of an installation portion 46 formed on the curtain plate 44 of the lower frame member 40, and the first inclination guide member 50 is disposed in the first installation recess 47. In the state in which the screw is inserted, the screws inserted into the through holes 112a formed in the upper facing plate portion 112 of the first lower connection fitting 110 and the through holes 54 formed in the first inclined guide member 50 are inserted into the installation portion 46 ( The first installation recess 47) is fixed by screwing into the screw hole 47a. That is, since the first inclined guide member 50 can be fixed in conjunction with the connection of the first lower connecting bracket 110 to the lower frame member 40 (screen plate 44), the first inclined guide member 50 is easily attached. be able to.
そして、前記第1の傾斜案内部材50を前記設置部46に固定した際には、該第1の傾斜案内部材50における第1の傾斜面部52aが前記第1の下連結金具110の上側対向板部112に形成した貫通孔112bに臨むから、中枠12の閉成時に中枠12の下端部を第1の傾斜面部52aに当接させることができる。また、第1の傾斜案内部材50における第1の傾斜面部52aを前記上側対向板部112の貫通孔112bに臨ませることで、該第1の傾斜面部52aに中枠12が接触した際に、当該第1の傾斜案内部材50が設置部46から外れることはない。
When the first inclined guide member 50 is fixed to the installation portion 46, the first inclined surface portion 52a of the first inclined guide member 50 is the upper facing plate of the first lower connecting bracket 110. Since it faces the through hole 112b formed in the portion 112, the lower end portion of the middle frame 12 can be brought into contact with the first inclined surface portion 52a when the middle frame 12 is closed. Further, by causing the first inclined surface portion 52a of the first inclined guide member 50 to face the through hole 112b of the upper facing plate portion 112, when the middle frame 12 comes into contact with the first inclined surface portion 52a, The first inclined guide member 50 does not come off from the installation portion 46.
また、前記第2の傾斜案内部材56は、該第2の傾斜案内部材56に形成された係止片59を下枠部材40の幕板44に形成した第2設置凹部48の係合溝48bに対して前方から差込むと共に、該第2設置凹部48に形成した係合孔48aに対して第2の傾斜案内部材56に形成した係合フック57,57を係合するだけで、当該第2設置凹部48に固定される。一方で、第2の傾斜案内部材56の係合フック57と第2設置凹部48の係合孔48aとの係合を解除すると共に、該第2の傾斜案内部材56を前方へ移動して前記係止片59と係合溝48bとの係合を解除するだけで、当該第2の傾斜案内部材56を第2設置凹部48から取り外すことができる。すなわち、前記第2の傾斜案内部材56を前記第2設置凹部48に対して簡単に着脱できる。
Further, the second inclined guide member 56 includes an engaging groove 48b of a second installation recess 48 in which a locking piece 59 formed on the second inclined guide member 56 is formed on the curtain plate 44 of the lower frame member 40. The engagement hooks 57, 57 formed on the second inclined guide member 56 are engaged with the engagement holes 48a formed in the second installation recess 48 from the front. 2 Fixed to the installation recess 48. On the other hand, the engagement between the engagement hook 57 of the second inclined guide member 56 and the engagement hole 48a of the second installation recess 48 is released, and the second inclined guide member 56 is moved forward to The second inclined guide member 56 can be removed from the second installation recess 48 simply by releasing the engagement between the locking piece 59 and the engagement groove 48 b. That is, the second inclined guide member 56 can be easily attached to and detached from the second installation recess 48.
中枠12の開閉時に中枠12を単独で支持することのある第1の傾斜案内部材50や、中枠12の垂れ下がりが最も大きくなる開放端側を支持する第2の傾斜案内部材56には、当該中枠12の開閉を繰り返すにつれて傷や削れ等の摩耗が生じ易い。実施例では、前述のように、前記第1の傾斜案内部材50および第2の傾斜案内部材56の夫々を、前記下枠部材40の幕板44とは別部材として形成し、該幕板44の第1設置凹部47および第2設置凹部48に対して着脱交換し得るよう構成したから、傷や削れ等の摩耗が生じた第1の傾斜案内部材50や第2の傾斜案内部材56のみを交換でき、コストや廃棄物の低減を図り得る。
The first inclined guide member 50 that supports the middle frame 12 alone when the middle frame 12 is opened and closed, and the second inclined guide member 56 that supports the open end side where the hanging of the middle frame 12 is the largest As the opening and closing of the middle frame 12 is repeated, wear such as scratches and scrapes is likely to occur. In the embodiment, as described above, each of the first inclined guide member 50 and the second inclined guide member 56 is formed as a separate member from the curtain plate 44 of the lower frame member 40. Since the first installation recess 47 and the second installation recess 48 are configured to be detachable and replaceable, only the first inclined guide member 50 and the second inclined guide member 56 in which wear such as scratches or scraping has occurred are provided. It can be exchanged, and cost and waste can be reduced.
ところで、実施例に係るパチンコ機10では、遊技者が前記ハンドル部材17を操作してパチンコ球を遊技盤13の遊技領域13aに打出して遊技が開始されると、所定の制御条件に基づいて前記中枠12に設けられたスピーカユニット19から中低音が出力され、前記前枠14に設けられたスピーカユニット130から高音が出力される。このスピーカユニット19は、前記中枠12の左下部に設けられた第1箱状部28の第1空間S1内に、該第1箱状部28(蓋体32)の第1出力孔32aを介して出力部19aが前面に露出する状態で収容されている。この第1箱状部28は、前記収容部本体29に開設した第1の接続口30を介して第1空間S1の一部が中枠12の裏側に開口し、該中枠12を閉成した状態(すなわち、遊技が行なわれる状態)において、前記外枠11の下枠部材40に形成された第1ダクトD1の第2接続口71に連通接続する。また、前記第1ダクトD1は、前記下枠部材40に形成された第2箱状部78の第2空間S2に連通すると共に、第2空間S2は、当該第2空間S2内に設けた第2ダクトD2を介して、パチンコ機10の前面側に連通(開放)している。
By the way, in the pachinko machine 10 according to the embodiment, when the player operates the handle member 17 to launch the pachinko ball into the game area 13a of the game board 13 and the game is started, based on a predetermined control condition. Medium and low sounds are output from the speaker unit 19 provided in the middle frame 12, and high sounds are output from the speaker unit 130 provided in the front frame 14. The speaker unit 19 has a first output hole 32a of the first box-shaped portion 28 (lid 32) in the first space S1 of the first box-shaped portion 28 provided in the lower left portion of the middle frame 12. The output unit 19a is accommodated in a state exposed to the front surface. The first box-shaped portion 28 has a part of the first space S1 opened to the back side of the middle frame 12 through the first connection port 30 opened in the housing main body 29, and the middle frame 12 is closed. In this state (that is, a state where a game is performed), the second frame is connected to the second connection port 71 of the first duct D1 formed in the lower frame member 40 of the outer frame 11. The first duct D1 communicates with the second space S2 of the second box-shaped portion 78 formed in the lower frame member 40, and the second space S2 is provided in the second space S2. It communicates (opens) to the front side of the pachinko machine 10 via the two ducts D2.
すなわち、前記スピーカユニット19における出力部19aの前面から出力された効果音は、前記第1箱状部28の第1出力孔32aを介して直接遊技者側に出力されるのに対し、スピーカユニット19における出力部19aの背面から出力された効果音は、前記第1箱状部28の第1空間S1から第1ダクトD1、第2空間S2および第2ダクトD2の夫々を通って遊技者側に出力される。すなわち、実施例に係るパチンコ機10では、前記スピーカユニット19における出力部19aの背面から出力された効果音の経路が、所謂ダブルバスレフ構造に形成される。従って、前記スピーカユニット19における出力部19aの背面から出力された効果音は、第1空間S1から第1ダクトD1を通って第2空間S2に至る過程で低音域が増強されると共に、該第2空間S2から第2ダクトD2を通ってパチンコ機10の前面側に出力される過程で低音域がより一層増強されるから、音の拡がりを高め、パチンコ機10の音響効果の向上を図り得る。
That is, the sound effect output from the front surface of the output portion 19a in the speaker unit 19 is directly output to the player side through the first output hole 32a of the first box-shaped portion 28, whereas the speaker unit 19, the sound effect output from the back surface of the output portion 19a passes from the first space S1 of the first box-shaped portion 28 through the first duct D1, the second space S2, and the second duct D2. Is output. That is, in the pachinko machine 10 according to the embodiment, the path of the sound effect output from the back surface of the output unit 19a in the speaker unit 19 is formed in a so-called double bass reflex structure. Accordingly, the sound effect output from the back surface of the output unit 19a in the speaker unit 19 is enhanced in the low frequency range in the process from the first space S1 through the first duct D1 to the second space S2, and Since the bass range is further enhanced in the process of being output from the two spaces S2 through the second duct D2 to the front side of the pachinko machine 10, the sound spread can be enhanced and the acoustic effect of the pachinko machine 10 can be improved. .
ここで、前記第1箱状部28は、前記中枠12の左下部に設けられるため、該第1箱状部28内の第1空間S1の容積は比較的小さなものとなる。一方で、前記第2箱状部78は、パチンコ機10として機能するために必須の構成部材(制御装置や球処理機構、その他の遊技の実行に必要とされる構成)が設けられていない下枠部材40に設けるようにしたから、第2箱状部78内の第2空間S2の容積拡大を図り得る。すなわち、外枠11における中枠12より下方位置に第2箱状部78を設けることで、該第2箱状部78内に画成される第2空間S2を、中枠12に設けられた第1箱状部28に画成される第1空間S1以上の容積にできる。
Here, since the first box-shaped portion 28 is provided in the lower left portion of the middle frame 12, the volume of the first space S1 in the first box-shaped portion 28 is relatively small. On the other hand, the second box-shaped portion 78 is provided with no essential components (a control device, a ball processing mechanism, and other configurations necessary for the execution of the game) to function as the pachinko machine 10. Since the frame member 40 is provided, the volume of the second space S2 in the second box-shaped portion 78 can be increased. That is, by providing the second box-shaped portion 78 in the outer frame 11 below the middle frame 12, the second space S2 defined in the second box-shaped portion 78 is provided in the middle frame 12. The volume of the first space S1 or more defined in the first box-shaped portion 28 can be increased.
また、前記第1箱状部28の形成位置に対応して、前記下枠部材40(幕板44)の左端部側(第1の下連結金具110側)に第1ダクトD1を形成すると共に、第1箱状部28を中枠12の下端部に設けることで、外枠11における下枠部材40における幕板44の上面49からの第1ダクトD1の突出寸法を必要最小限とできる。このように、前記幕板44の上面49から前記第1ダクトD1が突出する寸法を小さくすることで、中枠12の開閉時等に各種配線が第1ダクトD1に引っかかるのを抑制でき、該中枠12の開閉操作を阻害するのを防止できる。なお、前記幕板44の上面49からの第1ダクトD1の突出寸法を小さくしたとしても、該第1ダクトD1の横幅寸法を大きくするようにしたことで、第1ダクトを通過する低音の増幅効果が損なわれることはない。また、前記第2箱状部78を構成する幕板44には、前記第1ダクトD1から離間する右端部側(第2の下連結金具120側)に第2出力孔76を開設したから、該第2出力孔76から第1ダクトD1に向けて延在する前記第2ダクトD2の長さを大きくできる。これにより、前記第2ダクトD2の容積を第1ダクトD1の容積以上に容易に形成することができる。そして、前記第2箱状部78の第2空間S2の容積を前記第1箱状部28の第1空間S1の容積以上に設定すると共に、前記第2ダクトD2の容積を第1ダクトD1の容積以上に設定することで、スピーカユニット19における出力部19aの背面側から出力される効果音(中低音)の低音域を、第1箱状部28(第1空間S1)、第1ダクトD1、第2箱状部78(第2空間S2)および第2ダクトD2により構成されたダブルバスレフ構造のエンクロージャを利用して効果的に増幅することができ、より豊かな低音を出力できる。
In addition, a first duct D1 is formed on the left end side (first lower connecting bracket 110 side) of the lower frame member 40 (curtain plate 44) corresponding to the formation position of the first box-shaped portion 28. By providing the first box-shaped portion 28 at the lower end portion of the middle frame 12, the projecting dimension of the first duct D1 from the upper surface 49 of the curtain plate 44 in the lower frame member 40 in the outer frame 11 can be minimized. Thus, by reducing the size of the first duct D1 projecting from the upper surface 49 of the curtain plate 44, it is possible to prevent various wires from being caught on the first duct D1 when the middle frame 12 is opened and closed. It is possible to prevent obstructing the opening / closing operation of the middle frame 12. Even if the projecting dimension of the first duct D1 from the upper surface 49 of the curtain plate 44 is reduced, the lateral width of the first duct D1 is increased so that the low-frequency amplification passing through the first duct is increased. The effect is not impaired. In addition, since the curtain plate 44 constituting the second box-shaped portion 78 has the second output hole 76 opened on the right end portion side (the second lower connecting bracket 120 side) spaced from the first duct D1, The length of the second duct D2 extending from the second output hole 76 toward the first duct D1 can be increased. Thereby, the volume of the second duct D2 can be easily formed to be larger than the volume of the first duct D1. And while setting the volume of 2nd space S2 of the said 2nd box-shaped part 78 more than the volume of 1st space S1 of the said 1st box-shaped part 28, the volume of the said 2nd duct D2 is set to the 1st duct D1. By setting the volume or more, the low frequency range of the sound effect (medium / low sound) output from the back side of the output unit 19a in the speaker unit 19 is changed to the first box-shaped portion 28 (first space S1) and the first duct D1. In addition, it is possible to effectively amplify by using the double bass reflex enclosure constituted by the second box-shaped part 78 (second space S2) and the second duct D2, and it is possible to output a richer bass.
また、前記第1ダクトD1および第2空間S2は、前記第2箱状部78を構成する前記幕板44とボックスカバー80とを組み付けるだけで形成されるから、該第1ダクトD1や第2空間S2を容易に形成することができる。また、前記ボックスカバー80に形成された延出片84や囲繞片88により、前記第1ダクトD1および第2空間S2の気密性を高めるよう構成してあるから、第1ダクトD1や第2空間S2での音漏れを抑制でき、低音域の増強効果が低下するのを防止し得る。更に、前記第1ダクトD1(ダクト前半体70)には、前記第1箱状部28の第1の接続口30に連通する第2の接続口71の開口縁に沿って突出片72が形成されて、中枠12の閉成時に該突出片72が第1の接続口30の開口内側に臨むよう構成されているから、第1箱状部28の第1空間S1と第1ダクトD1との間での音漏れも抑制され、低音域の増強効果が低下するのをより効果的に防止し得る。
Further, since the first duct D1 and the second space S2 are formed only by assembling the curtain plate 44 and the box cover 80 constituting the second box-shaped portion 78, the first duct D1 and the second space S2 are formed. The space S2 can be easily formed. In addition, the extending piece 84 and the surrounding piece 88 formed in the box cover 80 are configured to enhance the airtightness of the first duct D1 and the second space S2, so the first duct D1 and the second space Sound leakage at S2 can be suppressed, and the lowering of the bass enhancement effect can be prevented. Further, a protruding piece 72 is formed in the first duct D1 (duct first half 70) along the opening edge of the second connection port 71 communicating with the first connection port 30 of the first box-shaped portion 28. Since the protruding piece 72 faces the opening inside the first connection port 30 when the middle frame 12 is closed, the first space S1 and the first duct D1 of the first box-shaped portion 28 The sound leakage between the two is also suppressed, and it is possible to more effectively prevent the enhancement effect of the low frequency range from being lowered.
また、前記第2ダクトD2は、前記幕板44に形成した第2出力孔76に連通する第1連結筒部75を、前記ダクト部材90の第2連結筒部91に内挿し、前記ボックスカバー80と幕板44とを組み付けることで形成される。すなわち、後方および一側方に開放する簡単な形状のダクト部材90により、幕板44に沿って左右方向に延在する第2ダクトD2を形成し得るから、製造コストの増大を防止し得る。また、第2箱状部78を構成するボックスカバー80で第2ダクトD2の後壁を代用することで、第2箱状部78の薄型化が図られると共に、ダクト部材90の後方開口を塞ぐ蓋部材が不要となり、部品点数の低減を図り得る。
Further, the second duct D2 has a first connecting cylinder part 75 communicating with a second output hole 76 formed in the curtain plate 44 inserted in the second connecting cylinder part 91 of the duct member 90, and the box cover. 80 and the curtain 44 are assembled. That is, since the second duct D2 extending in the left-right direction along the curtain plate 44 can be formed by the duct member 90 having a simple shape that opens to the rear and one side, an increase in manufacturing cost can be prevented. Further, by substituting the rear wall of the second duct D2 with the box cover 80 constituting the second box-shaped portion 78, the second box-shaped portion 78 can be made thinner and the rear opening of the duct member 90 is blocked. A lid member becomes unnecessary, and the number of parts can be reduced.
また、前記ダクト部材90は、前記第2連結筒部91とダクト本体92との連設位置に形成した位置決め段部94に、該第2連結筒部91に内挿した第1連結筒部75が当接すると共に、該ダクト本体92に形成した第2支持ボス93の挿入孔93aに幕板44の第1支持ボス77を挿入することで、ダクト部材90の前方および上下左右方向への移動が規制される。そしてこの状態で、前記ダクト本体92における立上がり壁92bの後端縁に前記ボックスカバー80が当接することで、ダクト部材90の後方移動が規制される。すなわち、ネジ等を用いることなくダクト部材90を第2箱状部78に配設することができ、該ダクト部材90の取付作業を簡単に行なうことができる。
In addition, the duct member 90 includes a first connecting tube portion 75 inserted into the second connecting tube portion 91 in a positioning step portion 94 formed at a connection position between the second connecting tube portion 91 and the duct body 92. And the first support boss 77 of the curtain plate 44 is inserted into the insertion hole 93a of the second support boss 93 formed in the duct main body 92, so that the duct member 90 can be moved in the front and up / down / left / right directions. Be regulated. In this state, the box cover 80 comes into contact with the rear end edge of the rising wall 92b of the duct main body 92, whereby the backward movement of the duct member 90 is restricted. That is, the duct member 90 can be disposed in the second box-shaped portion 78 without using screws or the like, and the duct member 90 can be easily attached.

また、第2箱状部の第2空間に設けられる第2ダクトは、実施例の構成に限らず、一方の端部側で第2箱状部の第2開口部に連通すると共に他方の端部側で第2空間内に開口するよう形成すればよい。例えば、前記下枠部材の幕板には、前後に貫通する第2出力孔を開設し、前方および第1ダクト側の側方へ開放する箱状の第2のダクト部材を、該第2のダクトの閉鎖端部側に前記第2出力孔が臨ませて、当該第2のダクト部材の前方開放端に幕板の裏面を当接させることで、第2ダクトを形成することもできる。なお、前記ボックスカバーには、前記第2のダクト部材の後方および上下左右への移動を規制する規制片が形成されて、該ボックスカバーを幕板に組み付けた際に、該規制片が第2のダクト部材に当接して位置決めするよう構成される。この場合でも、簡単な形状の第2のダクト部材により第2ダクトを形成し得るから、製造コストの増大を防止し得る。また、第2箱状部を構成する幕板で第2のダクト部材の前面壁を代用することで、第2箱状部の薄型化を図り得ると共に、第2のダクト部材の前方開口を塞ぐ蓋部材が不要となり、部品点数の低減を図り得る利点がある。
The second duct provided in the second space of the second box-shaped portion is not limited to the configuration of the embodiment, and communicates with the second opening of the second box-shaped portion on one end side and the other end. What is necessary is just to form so that it may open in 2nd space by the part side. For example, the curtain plate of the lower frame member is provided with a second output hole penetrating in the front-rear direction, and a box-like second duct member that opens to the front and to the side on the first duct side is provided with the second output hole. A 2nd duct can also be formed by making the said 2nd output hole face the closed end part side of a duct, and making the back surface of a curtain plate contact | abut to the front open end of the said 2nd duct member. The box cover is formed with a restricting piece for restricting movement of the second duct member in the rear and up / down / left / right directions. When the box cover is assembled to the curtain plate, the restricting piece is a second piece. It is comprised so that it may contact | abut to the duct member of and position. Even in this case, since the second duct can be formed by the second duct member having a simple shape, an increase in manufacturing cost can be prevented. Further, by substituting the front wall of the second duct member with a curtain plate that constitutes the second box-shaped portion, the second box-shaped portion can be thinned and the front opening of the second duct member is blocked. There is an advantage that the lid member becomes unnecessary and the number of parts can be reduced.
