Is possible.

  As shown in FIG. 5, the locking device 20 includes a locking rod 21 that slides up and down, hook pieces 22 and 23 that are provided in the vicinity of both upper and lower ends of the locking rod 21, and project to the rear side. It is generally composed of a cylinder lock 24 that can be moved up and down and locked. A cam piece (not shown) is provided at the rear end of the lock shaft of the cylinder lock 24, and the cam piece engages with an opening (not shown) provided on one side of the lock rod 21, By inserting a key into the cylinder lock 24 from the front side of P and turning it, the locking rod 21 is formed to slide up and down. Further, the flange pieces 22 and 23 provided on the locking rod 21 are formed so as to be able to engage with the opening portions 25 and 26 provided on the engaging portion of the right frame portion 1d of the outer frame 1.

  The locking device 20 shown in FIG. 5 is attached in the vicinity of the right end of the middle frame 2 as shown in FIG. 2, and the front of the raised portion U of the right frame portion 1d as shown in FIG. It is formed as a region 18 in which 20 locking rods 21 and flange pieces 22, 23 are arranged.

  The locking rod 21 of the locking device 20 has a spring and is formed so as to always be biased upward, and the flange pieces 22 and 23 engage with the upper side of the openings 25 and 26 and normally do not open to the front side. So that it is locked. On the other hand, by rotating the cylinder lock and moving the locking rod 21 downward, the hook pieces 22 and 23 are slid downward so that the state engaged with the upper side of the openings 25 and 26 is released. Then, the lock of the locking device 20 is released. As a result, the middle frame 2 to which the locking device 20 is attached is released from the state of being fixed to the outer frame 1, and is opened forward by rotating around the support members 14 and 15.

  The left frame portion 1c of the upper, lower, left, and right frame portions of the outer frame 1 is a flat portion F having a flat front end on the front side of the pachinko machine P as shown in FIG. The rear end side that is the rear side of the pachinko machine P of the frame portion is formed as a raised portion U that is wider than the flat portion F.

  The raised portions U of the left frame portion 1c and the right frame portion 1d are raised toward the accommodating side of the middle frame 2 located on the inner side surrounded by the frame portions 1a to 1d of the outer frame 1, and The outer surface of the outer frame 1 in the raised portion U is formed as a flat surface that continues to the flat portion F.

  In the present invention, the engaging portion of the first machine frame is preferably provided on the rear end side of the frame portion that does not include a portion facing the game board holding portion. That is, as shown in FIG. 6 (b), the portion formed as the raised portion U in the left frame portion 1c and the right frame portion 1d is the game board holding portion 9 when the middle frame 2 is accommodated in the outer frame 1. The portion facing the mechanism set board 8 is not included. Further, the flat portion F of the left frame portion 1c and the right frame portion 1d includes a portion facing the game board holding portion 9 when the middle frame 2 is accommodated in the outer frame 1, and the opening direction of the middle frame 2 (arrow in the figure) The opening direction of the middle frame 2 indicated by R is the front end side located on the front side of the pachinko machine P). As a result, as shown in FIG. 6 (b), the game board holding part 9 is located between the flat parts F and F of the left frame part 1c and the right frame part 1d, and the mechanism between the raised parts U and U is a mechanism. Set board 8 is located.

  As shown in FIG. 2, the game board holding unit 9 has an opening area for inserting the game board 3 of the middle frame 2, a game board holding surface that surrounds the opening area of the middle frame 2 and holds the periphery of the game board 3. , And a middle frame portion on which the holding surface is formed. That is, the game board holding unit 9 is located between the left frame 1c and the right frame 1d in the left-right direction of the pachinko machine P, as shown in FIG. It is formed within the range of the length of the flat portion F of the frame portion 1c and the right frame portion 1d. The portion of the frame portion facing the game board holding portion 9 means a portion corresponding to the so-called thickness direction length of the game board holding portion 9 in the longitudinal direction of the gaming machine. The length of the flat portion F of the frame portions 1c and 1d of the outer frame 2 is at least longer than the length of the game board holding portion 9 in the longitudinal direction of the gaming machine.

  The left frame portion 1c and the right frame portion 1d, which are frame portions composed of the raised portion U and the flat portion F, are formed such that the raised portion U protrudes behind the game board holding portion 9. If formed in this way, the outer surface of the outer frame 1 can be formed smoothly, and the gaming board 3 can be taken out from the front of the gaming machine. Furthermore, sufficient strength as a gaming machine frame can be secured.

In the present invention, the engaging portion is preferably provided continuously in the longitudinal direction of the frame portion at the rear end of the frame portion, like the raised portions U of the frame portions 1c and 1d in the outer frame 1 of the embodiment. The raised portions U may be formed intermittently and discontinuously. However, when the raised portions U are formed continuously in the longitudinal direction as shown in FIG. 3, there is an advantage that the frame portion can be easily formed. Further, when the raised portions U are continuously formed, the strength of the outer frame can be further improved.

  In the present invention, when the raised portion U is formed in the frame portion, the shape of the raised portion U in the frame portion is not limited to the P-shaped cross section, and the cross section is a polygonal shape such as a triangular shape or a rectangular shape, or a polygonal shape. A shape with chamfered corners, a circular cross-section or a circle-like shape is also included.

  The raised portion U is raised so as to bulge from the rear end of the frame portion to the front end direction with a required length. The required length is formed to be at least larger than the thickness of the flat plate portion F. Further, when the raised portion U is formed by bending a flat plate material, the bent tip is formed so as to face the direction of the plate material. The bent tip may be separated without being in direct contact with the plate material, but if the tip and the plate material are in contact, the resistance force when a stress such as torsion is applied to the outer frame 1 is increased. It is preferable because impact resistance is improved.

  Of the frame portions 1a to 1c of the outer frame 1, the frame portion forming the raised portion U as the engaging portion is preferably at least the right frame portion 1d in which the openings 25 and 26 of the locking device 20 are formed, Furthermore, the left frame portion 1 is preferably formed in the same manner, and more preferably the upper frame portion 1a.

  The outer frame 1 is formed by molding each frame member and using a joining member or the like, or forming each end of the frame member as a joining portion and using the joining member without using the joining member. It can form as a frame by joining using a joining means. Further, a reinforcing member or the like can be used for the joint portion.

  The frame portion 1d having the engaging portion is preferably formed from a metal such as an aluminum alloy or a magnesium alloy. Further, when the frame portion is made of metal, the frame portion (upper frame portion 1a, lower frame portion 1b, left frame portion 1c, etc.) other than the right frame portion 1d having the engaging portion is also formed of metal, The entire outer frame 1 may be made of metal. The metal frame is obtained by metal forming. Specific examples of metal forming include a method of forming by deforming extrusion of an aluminum alloy or a magnesium alloy.

  By making the frame portions 1a to 1d constituting the outer frame 1 made of metal, it is possible to impart excellent strength to the frame portion and ensure sufficient strength of the gaming machine. In addition, when the frame portion 1d provided with the engagement portion is made of metal, compared to a wooden or resin-molded frame portion, it has superior rigidity and heat resistance. A part of the frame part can be dissolved to prevent illegal acts such as coming into contact with the inside of the aircraft from the outside.

  Moreover, since the frame parts 1a to 1d constituting the outer frame 1 are made of metal, it is possible to secure a wide discharge area without limiting the part where the ground wire is connected to the frame part. Improvement can be aimed at and the freedom degree of design can be ensured.

  In addition, when an aluminum alloy is used as the metal of the frame portions 1a to 1d, deterioration is less likely to occur compared to the resin even when reheated and dissolved during reuse. Therefore, it can be used again as a molding material for the frame, and the recyclability can be improved. And by improving recyclability, it is possible to provide a gaming machine that can suitably cope with effective use of resources.

  In addition, when a metal having higher rigidity than that of resin or wood is adopted as the molding material for each frame portion, a thinner frame portion can be formed as compared with a wooden or resin frame portion. As a result, the flat part F of the frame part can be formed into a thinner flat plate shape, and the game board holding part 9 in the middle frame 2 can be expanded more efficiently.

  Further, since the flat part F of the frame parts 1c and 1d is located in the opening direction of the middle frame 2 of the pachinko machine P, the raised part U of the frame part is located at the rear end opposite to the opening direction of the middle frame 2. Thus, the middle frame 2 can be reliably opened without obstructing the opening of the middle frame 2 with respect to the outer frame 1.

  The frame portion composed of the flat portion F and the raised portion U is preferably arranged so that the flat portion F side is positioned in the take-out direction of the game board 3 in the game board holding part 9. If the outer frame 1 is configured such that the raised portion U side is positioned in the take-out direction of the game board 3, the raised portion U becomes in the way and it becomes difficult to take out the game board 3. As a result, in order to actually take out the game board 3, the middle frame 2 is opened so that the raised portion U of the outer frame that is an obstacle to the direction of taking out the game board 3 does not get in the way, The board 3 is taken out, and the opening operation of the middle frame becomes complicated. On the other hand, when the flat portion F is positioned in the take-out direction of the game board 3, since the flat portion F is formed in a thin flat plate shape, it does not become an obstacle to the take-out direction of the game board 3. The game board 3 can be easily attached and detached while the middle frame 2 remains attached to the outer frame 1 without opening the middle frame 2 having the game board holding portion 9 from the outer frame 1. The game board 3 can be easily attached and detached.

  FIG. 6 (a) shows a horizontal cross section of the pachinko machine shown in Patent Document 1, and FIG. 6 (b) shows a horizontal cross section of the pachinko machine of this embodiment. FIG. 7 is a perspective view of a main part showing a locking device and a right frame part of a conventional pachinko machine. In the figure, an arrow R indicates the opening direction of the middle frame and the direction of taking out the game board. As shown in FIGS. 6 (a) and 7, in the conventional pachinko machine, when the locking device 110 is locked, the locking rod 112 is urged upward by the spring, and the hook 112 is engaged with the lower side portion of 101c. Match. The side surface side of the locking plate 101c of the right frame portion 101b has a cut portion 101d and can be accessed from the side surface side. Further, the rear side of the portion of the locking plate 101c with which the heel side 112 is engaged is not entirely covered by the bent portion of the frame portion, and therefore can be accessed from the rear side. Thus, if the hook 112 can be accessed from the outside of the machine by engaging the locking plate 101c, there is a possibility that the hook engagement state is released by making contact with a metal rod or the like.

  On the other hand, in the pachinko machine according to the present embodiment shown in FIGS. 5 and 6 (b), the portion provided with the openings 25 and 26 of the right frame portion 1d has only the front portion opened, and the side portion Both the rear side and the rear side are formed as walls, and it is impossible to access the engaging portions of the side edges 22 and 23 and the openings 25 and 26 from the side and the rear side. Therefore, like the conventional pachinko machine described above, the locked state of the locking device can be released, and the middle frame and the front frame can be arbitrarily opened to prevent illegal acts that directly access the game board.

  Furthermore, since the engaging portion of the right frame portion 1d of the present embodiment is formed as a raised portion that is continuous in the longitudinal direction, and all the portions other than the opening are formed as walls, the front surface excluding the opening, It is possible to prevent unauthorized actions by preventing access to the engaging portions of the sides 22 and 23 from the side surface and the rear surface.

  Further, in the pachinko machine of the present embodiment, as shown in FIG. 6B, the left frame portion 1c is formed as a flat portion F on the front end side including a portion facing the game board holding portion 9, and is provided with an engaging portion. Since the raised part U is provided avoiding the game board holding part 9, the game board holding part 9 can be expanded to a position adjacent to the left frame part 1c. The strength of the entire outer frame 1 can be imparted to the raised portion U of the frame portion. Since the raised portion U is formed on the rear end side not including the portion facing the game board holding portion 9, there is no possibility of interfering with the area of the game board holding portion 9. On the other hand, in the conventional pachinko machine, as shown in FIG. 6 (a), the left outer frame 101a is formed in a U-shaped cross section, and the right outer frame 101b is a member having a U-shaped cross section and a middle portion of the member. A plate-like body protruding in the direction of the game board holding portion is erected as an opening 101c, a front frame 104 and a middle frame 102 are provided on the front side of the outer frame, and between the left outer frame 101a and the right outer frame 101b The game board holding portion 109 is used as a storage area for the middle frame. At this time, the front end edge of the left outer frame 101a is formed between the game board holding part 109 and the left outer frame 101a so as to stand vertically to the size of the width S on the game board holding part side. For this reason, the dead space 110 is formed by the width S.
