The third connection fitting 17 has a projection (rotation fulcrum) 17A for attaching the main body base 20. In a state where the third connection fitting 17 is fixed to the mounting piece 12A, the protrusion 17A is located at the center in the width direction of the mounting piece 12A. On the front end face of the mounting piece 12A, a fourth connection fitting 19 is disposed at the left end (right side shown in FIG. 3). A small hole 19 a is formed in the fourth connecting bracket 19.
[0027]
On the other hand, the width of the main body base 20 is set to be approximately half the depth of the outer frame 10. The main body base 20 is accommodated in the front half of the outer frame 10. A back mechanism panel 131 is attached to the rear surface 20B side of the main body base 20 as shown in FIG.
Next, a structure for attaching the main body base 20 and the upper door 30 to the outer frame 10 will be described.
[0028]
A fifth connection fitting 24 is fixed to the left end portion (the right side shown in FIG. 3) of the upper end surface 20C of the main body base 20. The fifth connection fitting 24 is obtained by axially supporting two stacked flat plates at a rotation fulcrum 23, and an elongated hole 24a extending in the front-rear direction is formed in the upper flat plate. A small hole 26 is formed on the lower end surface 20D of the main body base 20 at the center in the front-rear direction. The fifth connection fitting 24 is fixed to the first connection fitting 16 of the outer frame 10 through the long hole 24a, and the small hole 26 is fitted into a protrusion 17a formed on the upper surface of the lower frame piece 12 of the outer frame 10. ing. Thereby, the main body base 20 is rotatable about the rotation fulcrum 23 and the protrusion 17a.
[0029]
Next, a structure for attaching the upper door 30 to the outer frame 10 will be described.
A sixth connection fitting 42 protruding to the front side is fixed to the lower left end (the right side shown in FIG. 3) of the lower door 40. A small hole 42 a is formed in the sixth connection fitting 42. In addition, a seventh connection fitting 49 protruding to the front side is fixed to the upper left end (the right side shown in FIG. 3) of the lower door 40. A small hole 49 a is formed in the seventh connection fitting 49.
[0030]
On the other hand, an eighth connecting fitting 41 protruding to the front side is fixed to the upper left end (the right side shown in FIG. 3) of the upper door 30. A small hole 41 a is formed in the eighth connection fitting 41. In addition, a ninth connection fitting 39 protruding to the front side is fixed to the lower left end (the right side shown in FIG. 3) of the upper door 30. A small hole 39 a is formed in the ninth connection fitting 39.
The shaft 50 is inserted into the small hole 19 a from below through the small hole 42 of the lower door 40, and the lower door 40 is attached to the outer frame 10. Further, simultaneously with the attachment of the lower door 40 to the outer frame 10, the upper door 30 is attached to the outer frame 10. In other words, the shaft 48 is inserted into the small hole 18 a of the second connection fitting 18 through the small hole 41 a of the seventh connection fitting 49, and the small size of the seventh connection fitting 49 is inserted through the small hole of the ninth connection fitting 39. The shaft 47 is inserted into the hole 49a. Thereby, in a state where the upper door 30 is attached to the outer frame 10 and the lower door 40, the upper door 30 can be rotated about the shafts 48 and 47, and the right side can be opened forward. it can.
[0031]
Incidentally, as shown in FIG. 4, the position of the pivot base 23 of the main body base 20 and the protrusion 17 a functioning as the pivot base is in the front-rear direction. It is set at the center of the outer frame 10 in the width direction so as to be retracted backward. On the other hand, the rotation fulcrums 48 and 47 of the upper door 30 are located substantially along the front end face 10 </ b> A of the outer frame 10. In other words, the upper door 30 is configured to be rotatable around the other fulcrum 48 and 47 that are not on the same vertical line as the side frame of the outer door 10 and the rotation fulcrum 23 and 19 of the main body base 20. Yes.
[0032]
Therefore, in a state where the upper door 30 and the lower door 40 that are in use of the pachinko machine 1 are closed, only the upper door 30 and the lower door 40 are present in front of the outer frame 10, and the main body base 20 is closed. In addition to the upper door 30 and the lower door 40, the appearance can be made cleaner compared to the conventional method in which a part of the main body base 20 projects in front of the outer frame 10. Moreover, since only the upper door 30 and the lower door 40 exist in front of the outer frame 10, when the outer frame 10 having the same width is used, the thickness of the entire pachinko machine 1 can be slightly reduced. Since the thickness of the pachinko machine 1 is thus reduced, it is possible to prevent the upper door 30 from protruding forward from the game island 200 as shown in FIG. Thereby, the external appearance can be made cleaner.
[0033]
Further, it is directly attached to the outer frame 10 instead of the upper door 30 and the main body base 20. For this reason, the weight of the upper door 30 to which the glass plates 51 and 52 are attached is not applied to the main body base 20, and the main body base 20 can be pulled out and pushed into the outer frame 10 side with a relatively light force.
Furthermore, the connecting brackets 16, 17, 24 for attaching the main body base 20 to the outer frame 10 and the connecting brackets 18, 41 for attaching the upper door 30 to the outer frame 10 are separate connecting brackets. 20 and the upper door 30 and the lower door 40 are supported by a common connecting bracket, the load received by each of the connecting brackets 16, 17, 18, 24, 41 is small, and each of the connecting brackets 16, 17, 18, 24 and 41 can be extended. Furthermore, since the load received by each of the connecting fittings 16, 17, 18, 24, 41 is small, the strength is sufficient even if the connecting fittings 16, 17, 18, 24, 41 having a simple configuration are used.
[0034]
Next, the glass unit G assembled on the rear surface of the upper door 30 will be described. FIG. 5 is an exploded perspective view of the glass unit G. FIG. The glass unit G is obtained by laminating and holding an outer glass plate 51 and an inner glass plate 52 at a predetermined interval on a glass plate holding member 76 composed of a spacer 71 and a front plate 72.
The front plate 72 has a substantially square shape. The front plate 72 is formed by processing a plate-shaped sheet metal, and a bent piece 74 bent backward is provided over the entire circumference. A circular opening 99 corresponding to the window 31 of the upper door 30 is formed in the central region of the front plate 72.
[0035]
The front plate 72 is provided with receiving portions 77 to 79 that engage with hooks 361, 362, 371, 372, 381, 391 described later of the upper door 30 around the opening 99. Each of the receiving portions 77 to 79 is formed by cutting a part of the sheet metal of the front plate 72 forward.
On the right end side (the left side shown in FIG. 5) of the front plate 72, two projecting pieces 81 are arranged at intervals in the vertical direction. Two projecting pieces 81 are also arranged on the left end side (the right side shown in FIG. 5) of the front plate 72 with an interval in the vertical direction. Each protrusion 81 is formed by being bent outward from the tip end of the bent piece 74. Each protruding piece 81 is formed with a screw hole 811 so that the screw hole 811 can be screwed from behind.
[0036]
Two projecting pieces 83 projecting upward are provided on the upper end side of the front plate 72. Two projecting pieces 84 projecting downward are provided on the lower end side of the front plate 72. These protrusions 83 and 84 are obtained by bending the sheet metal of the front plate 72 outward from the front end portion of the bent piece 74, and screw insertion holes 831 and 841 are formed at substantially central portions thereof. .
The spacer 71 is a resin-made plate-like member whose outer shape is substantially square, and a circular opening 98 corresponding to the window portion 31 of the upper door 30 is formed in the center region. The spacer 71 is configured by ribs 85 combined in a lattice shape. For this reason, the weight of the spacer 71 can be reduced while keeping the interval between the outer glass plate 51 and the inner glass plate 52 at a predetermined interval.
[0037]
An outer glass plate accommodation space for accommodating the outer glass plate 51 is defined on the front surface side of the spacer 71 along the right side edge (left side shown in FIG. 5) and the left side edge (right side shown in FIG. 5). Projections 78 and 79 are provided. The protrusions 78 and 79 protrude forward from the spacer 71 and extend from the upper end portion to the lower end portion of the spacer 71 (not shown).
An inner glass plate accommodation space for accommodating the inner glass plate 52 is defined on the rear surface side of the spacer 71 along the right side edge (left side shown in FIG. 5) and the left side edge (right side shown in FIG. 5). Guides 87 and 88 are provided. The guides 87 and 88 protrude rearward from the spacer 71 and extend from the upper end portion to the lower end portion of the spacer 71. The inner glass plate 52 can be inserted between the guides 87 and 88 from above. When the guides 87 and 88 are inserted, the right end side 52a (the left side shown in FIG. 5) of the square inner glass plate 52 is inserted. ) And the left end side 52b (the right side shown in FIG. 5). On the lower end side 71c of the spacer 71, a receiving projection for receiving the lower end side (lower end edge) 52c of the inner glass plate 52 in which the inner glass plate 52 is inserted into the inner glass plate accommodation space from the left end portion to the right end portion. A strip (receiving projection) 86 projects rearward. On the rear surfaces 87B and 88B of the guides 87 and 88, pressing metal fittings 100 for pressing the inner glass plate 52 accommodated in the inner glass plate accommodating space to the spacer 71 side are arranged on the upper and lower portions, respectively. . In addition, although it is set as the structure which provides the two metal fittings 100 for pressing corresponding to the one end side of the inner glass plate 52, one may be sufficient and three or more may be sufficient.
[0038]
Two protrusions 89 are formed on the left end surface (right side shown in FIG. 5) of the spacer 71. Although not shown in FIG. 5, two similar protrusions 89 are formed on the right end surface (see FIG. 5). (Left side shown by 5). A screw insertion hole 891 is formed in the protrusion 89.
After the outer glass plate 51 is fitted in the outer glass plate housing space formed on the front surface 71A side of the spacer 71, the front surface 71A side is covered with the front plate 72, and the screw 91 is screwed into the screw hole 811 through the screw insertion hole 891. Conclude. In this state, the outer glass plate 51 is sandwiched between the spacer 71 and the front plate 72, whereby the outer glass plate 51 is reliably held in the outer glass plate housing space.
[0039]
Since the spacer 71 is plate-shaped, the corners of the outer glass plate 51 can be supported by the spacer 71 and the front plate, whereby the outer glass plate 51 is firmly held by the glass plate holding member 76.
Note that the opening 98 formed in the spacer 71 and the opening 99 formed in the front plate 72 have the same circular shape as the window 31 of the upper door 30, and the size thereof is preferably the same as that of the window 31. As long as the main body base 20 and the upper door 30 are closed, the shape is not limited to a circular shape and may be a rectangular shape or an elliptical shape as long as the window portion 31 of the upper door 30 is not obstructed.
[0040]
Next, the pressing metal fitting 100 disposed on the rear surfaces 87B and 88B of the guides 87 and 88 will be described in detail. Each pressing metal fitting 100 has the same configuration. FIG. 6 is a perspective view showing the structure of the pressing metal fitting 100. FIG. 6 illustrates the pressing metal fitting 100 at the upper left of the four pressing metal fittings 100 as an example.
The pressing metal fitting 100 includes a substantially U-shaped base portion 101. Specifically, the base portion 101 includes a bottom plate 102 attached to the rear surface 87B of the guide 87 and a pair of side plates 103 and 104 rising from both ends of the bottom plate 102. A shaft 105 is spanned between the upper end portions of the side plates 103 and 104, and a torsion coil spring 106 is rotatably fitted around the shaft 105. A cylindrical pressing roller (pressing portion) 107 is attached to one end portion 106 a of the torsion coil spring 106, and a long lever (operation member) 108 is attached to the other end portion 106 b of the torsion coil spring 106. Yes. An engagement protrusion (engagement portion) 109 is formed at the left end portion of the lever 108, and both end portions 106 a and 106 b of the torsion coil spring 106 are displaced in the neutral state of the torsion coil spring 106. The pressing roller 107 and the lever 108 are attached to the torsion coil spring 106, and the pressing roller 107 is displaced according to the operation of the lever 108.
[0041]
An engagement hole (engagement portion) 110 is formed in the side plate 103 (on the right side in FIG. 6), and the engagement protrusion 109 is fitted into the engagement hole 110 while the lever 108 is pushed down to the front side. It can be put in.
When the lever 108 is pushed forward, the pressing roller 107 is displaced forward and comes into contact with the rear surface of the inner glass plate 52. Thereafter, the lever 108 is pushed further forward against the drag of the torsion coil spring 106, and then the engagement protrusion 109 is fitted into the engagement hole 110. In a state where the engagement protrusion 109 is fitted in the engagement hole 110, the pressing roller 107 presses the inner glass plate 52 forward.
[0042]
Further, when the lever 108 is lightly pressed to the front side again and then pulled out to the right side, the engagement between the engagement protrusion 109 and the engagement hole 110 is released, and the inner glass plate 52 is fixed. Canceled. For example, when the inner glass plate 52 is broken, the four pressing metal fittings 100 are sequentially operated to release the pressing of the inner glass plate 52, and then the inner glass plate 52 can be pulled upward.
Since the inner glass plate 52 can be easily fixed / unlocked in this way, when the inner glass plate 52 is broken, it is possible to replace only the inner glass plate 52 at the game store. The glass plate holding member 76 can be removed from the upper door 30 and replaced with another glass plate holding member, or the screw 91 of the glass plate holding member 76 removed from the upper door 30 is removed to remove only the outer glass plate 51. It can also be exchanged.
[0043]
