  Here, the present invention has been made in the background as described above, and the problem to be solved is to effectively prevent illegal acts often performed from the side of a pachinko machine, It is an object of the present invention to provide a pachinko machine having a novel structure capable of effectively securing the fixing strength of a part to a front frame.

  Hereinafter, embodiments of the present invention made to solve the above-described problems will be described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  That is, the present invention includes a front frame that is connected to the outer frame so as to be openable and closable and to which a gaming board is attached, and in the pachinko machine in which the gaming machine component is disposed on the back side of the front frame, It is characterized in that pressing means for fixing to the front frame is provided, and a wall portion covering the side surface of the pressing means is provided in the gaming machine part.

  According to the present invention, even when jigs or the like are illegally inserted from the side surface of the pachinko machine, the pressing of the jig is prevented by the wall portion covering the side surface of the pressing means from contacting the pressing means. It is possible to reduce the possibility that the fixed state is released when the means is operated from the outside. As a result, it is possible to effectively secure the fixing strength of the gaming machine parts to the front frame. In addition, the wall part in this invention may be provided so that attachment or detachment with respect to game machine components may be provided, and may be provided fixedly. In the present invention, it is sufficient that at least the wall portion covers the side surface of the pressing means. Therefore, for example, a cover member provided with a wall portion that surrounds the entire top, bottom, left, and right of the pressing means and the back may be formed separately from the gaming machine parts and attached so as to cover the back of the pressing means. Or, since illegal insertion of jigs and the like is often performed from the side surface of the pachinko machine, only the wall portion covering the pressing means is integrally formed on the gaming machine part without covering the back surface of the pressing means, etc. You may do it. For example, if only the wall portion that covers the side surface of the pressing means is formed, the employee of the hall or the like can operate the pressing means from the back of the pachinko machine while effectively preventing unauthorized contact with a jig or the like from the side surface. It can be done easily.

  In the present invention, the specific structure of the pressing means for attaching the gaming machine part to the front frame is not particularly limited, and a conventionally known structure can be appropriately employed. For example, it may be fixed with screws or bolts, or may be detachable without using a tool, for example, by adopting a latch mechanism.

It has been. The prize ball tank 66 is not necessarily provided in the main set 62. For example, the prize ball tank 66 may be provided on the base frame 16 and connected to the tank rail 70 in the attached state of the main set 62. good.

  The winning ball path 68 is connected to the tank rail 70 at the upper end and is curved outward, and then extends vertically downward on the side of the central window 64 (right side in FIG. 5 in this embodiment). It is considered a road. The lower end portion of the prize ball passage 68 is connected to the introduction portion 72 and communicates with the internal passage 73 formed inside the frame member 65 via the introduction portion 72.

  The internal passage 73 is a guide path that extends in the vertical direction in the main set 62. The upper end portion of the internal passage 73 is connected to the prize ball passage 68 through the introduction portion 72, while the lower end portion is an opening portion 74 opened below the central window 64 in front of the frame member 65. It is said that. The opening 74 is opened in a substantially rectangular shape, and has a size substantially equal to the outer shape of the fitting rib 59 of the through hole 58 formed in the base frame 16.

  As described above, the prize ball passage 68, the introduction portion 72, and the internal passage 73 are communicated with each other, and the opening portion opened from the prize ball tank 66 disposed on the back side of the main set 62 to the front of the main set 62. There are 74 guide paths for game balls. Thus, in the present embodiment, the payout passage is configured including the prize ball passage 68, the introduction portion 72, and the internal passage 73.

  A prize ball payout device 76 is disposed above the introduction portion 72. The prize ball payout device 76 houses a prize ball payout mechanism using a prize ball motor such as a pulse motor as a drive source, and the prize ball payout device 76 is rotated every time the rotation axis of the prize ball motor rotates by a unit amount. A game ball as a prize ball is paid out one by one to the introduction part 72. In addition, a discharge port 78 penetrating in the thickness direction of the frame member 65 is opened in front of a portion of the frame member 65 where the prize ball payout device 76 is attached. Connected with holes. Thus, when the game balls stored in the prize ball tank 66 are discharged, the game balls are discharged from the discharge port 78 by the prize ball payout device 76. The portion where the discharge port 78 is formed is overlapped with a gap that allows the game board 14 to pass the game ball, and the game ball discharged from the discharge port 78 passes through the back side of the game board 14. The guide ball is guided to a ball escape path of a missed ball (not shown).

  Further, below the central window 64 on the back surface of the frame member 65, a main control board case 80 for accommodating a main control board for controlling the game operation, power is obtained from the outside, and power is distributed to each control board and driving device. A power supply board case 82 is provided to accommodate the power supply board to be supplied. The main control board case 80 is provided with a conventionally known sealing means 84 so that it is not easily opened. As described above, in this embodiment, the main set 62 is provided with a plurality of models by providing the main ball 62 with a game ball payout path, a power supply board, and a main control board that can be used in common with a plurality of models. It can be used in common.

  The main set 62 having such a structure is attached to the back surface of the base frame 16 as shown in FIG. Particularly in the present embodiment, bearings 86 projecting rearward over a predetermined dimension on the upper and lower ends of one side in the width direction on the back surface of the base frame 16 (right side in FIG. 7 in the present embodiment), 88 is provided. These bearings 86 and 88 have shaft holes 90 and 92 each having a long hole shape extending in the front and back direction of the base frame 16 through the bearings 86 and 88 in the thickness direction, as schematically shown in FIG. Is formed. On the other hand, shafts 94 and 96 projecting downward are provided on the upper and lower ends of the main set 62 on the same side as the bearings 86 and 88 (right side in FIG. 7 in this embodiment). These shafts 94.96 are inserted into the shaft holes 90 and 92 from above and the bearings 86 and 88 and the shafts 94 and 96 are connected to each other to form a hinge mechanism. The base frame 16 is detachably attached and can be opened and closed. As described above, in this embodiment, the bearings 86 and 88 and the shafts 94 and 96 constitute attachment means.

  Furthermore, mounting holes 98a, 98b, 98c, and 98d for mounting a ny latch 104, which will be described later, are provided at positions near the four corners on the back surface of the base frame 16 (see FIG. 4). The mounting holes 98 are preferably formed at positions close to the four corners of the main set 62 attached to the base frame 16, but the mounting positions of the mounting holes 98 are determined according to the fixing strength of the main set 62 and the arrangement with other members. It is set in consideration of the installation space. In particular, in the present embodiment, the attachment hole 98a is formed slightly inward from the right end portion at the upper end portion in the rear view of the base frame 16, and the attachment hole 98d is formed at the lower end portion in the rear view of the base frame 16. It is formed slightly inward from the left end portion.

  The main set 62 hinged to the base frame 16 so as to be openable and closable by bearings 86 and 88 and shafts 94 and 96 is closed so as to be superimposed on the back surface of the base frame 16. Insertion holes 100a, 100b, 100c, and 100d penetrating through the frame member 65 are provided in portions of the member 65 that overlap the mounting holes 98a, 98b, 98c, and 98d, respectively. Particularly in the present embodiment, the mounting holes 98a, 98c, and 98d are formed through the rear end face of the cylindrical portion 101 protruding rearward as shown in FIG. 9 as an example of the mounting hole 98a. On the other hand, a cylindrical outer fitting portion 102 protruding forward is formed on the front surface of the insertion holes 100a, 100c, and 100d. The inner diameter of the outer fitting portion 102 is slightly larger than the outer diameter of the cylindrical portion 101. Thus, the outer fitting portion 102 is fitted on the cylindrical portion 101 in a state where the main set 62 is closed.

  Then, with the main set 62 closed, the ny latch 104 is inserted from the back of the insertion holes 100a, 100b, 100c, and 100d and attached to the attachment holes 98a, 98b, 98c, and 98d. The frame 16 is fixed in a closed state. The ny latch 104 in this embodiment is composed of a grommet 105 and a plunger 106 as schematically shown in FIG.

  The grommet 105 is an integrally molded part in which a disc part 107 having a disc shape and a tip part 108 divided into four in the circumferential direction are connected by a cylindrical part 109, and the tip part is obtained by the elasticity of the member. 108 can be opened and closed. An insertion hole 110 that penetrates the disc portion 107 and the cylindrical portion 109 is formed on the central axis of the grommet 105. On the other hand, the plunger 106 is formed with an operation portion 111 having a truncated conical shape whose diameter is reduced in the axial middle portion, and an action portion 112 extending in the axial direction from the operation portion 111 with a substantially cylindrical shape. Note that the distal end portion and the proximal end portion of the action portion 112 are slightly larger in diameter, and the diameter dimensions of the distal end portion and the proximal end portion of the action portion 112 are substantially equal to the inner diameter dimension of the insertion hole 110. .

  The action portion 112 of the plunger 106 is inserted into the insertion hole 110 of the grommet 105 from the rear in the axial direction, and the tip portion 108 of the grommet 105 is pushed by the action portion 112 being pushed in the tip direction. Is pushed from the inside.

  The ny latch 104 having such a structure is inserted into the insertion hole 100a from the back surface of the frame member 65 as shown in FIG. 9 as an example of the insertion hole 100a, and the tip end portion 108 of the grommet 105 is inserted into the mounting hole 98a. Is done. When the plunger 106 is pushed in the distal direction, the distal end portion 108 is opened and held in an open state, so that the frame member 65 and the cylindrical portion 101 are moved between the distal end portion 108 and the disc portion 107. The end face is clamped. As a result, the frame member 65 is fixed in a state of being pressed against the base frame 16.

  Here, as shown in FIG. 7, since the central window 64 is provided in the main set 62, for example, the liquid crystal display 113 disposed on the back surface of the game board 14 when the main set 62 is closed. Further, members such as the effect control board 114 and the sound / light control board 116 are disposed in the central window 64 of the main set 62 so as not to interfere with the main set 62. Further, particularly in the present embodiment, the shaft holes 90 and 92 constituting the hinge mechanism have a long hole shape extending in the front and back direction of the base frame 16. As a result, when opening the main set 62, the entire main set 62 is first moved rearward along the shaft holes 90, 92 so that the shafts 94, 96 are positioned at the rear ends of the shaft holes 90, 92. In this state, that is, the main set 62 can be rotated at a predetermined distance from the base frame 16. Thus, when the main set 62 is opened, the liquid crystal display 113 or the like disposed on the back surface of the game board 14 is not interfered. Similarly, when the main set 62 is closed, after the shafts 94 and 96 are positioned at the rear ends of the shaft holes 90 and 92, the main set 62 is rotated in the closing direction in advance, and then the main set 62 is closed. Since the whole can be brought close to the base frame 16, the main set 62 is not superimposed on the liquid crystal display 113 from the oblique direction, and the possibility of interference with each other is reduced.

  Further, particularly in the present embodiment, an attachment hole 118 having the same structure as the attachment hole 98a and the like is formed below the right side of the through hole 58 in the base frame 16 (see FIG. 4). At the same time, an insertion hole 120 having the same structure as the insertion hole 100 a is provided in the frame member 65 at a position overlapping the mounting hole 118 in the thickness direction of the frame member 65. Then, with the main set 62 closed, the insertion hole 120 is overlapped with the mounting hole 118, and the nail latch 122 having the same structure as the above-described nail latch 104 is attached from the back surface of the mounting hole 118. The portion of the set 62 where the opening 74 is formed is fixed so as to be pressed against the base frame 16. Thus, in the present embodiment, the pressing means is configured including the mounting hole 118, the insertion hole 120, and the ny latch 122.

  In the pachinko machine 10 having such a structure, the main set 62 is pressed against the base frame 16 by the ny latch 122 at a position close to the through hole 58, so that the main set 62 in the portion where the through hole 58 is formed. It is possible to effectively secure the fixing strength to the base frame 16 and to prevent a gap from being formed between the base frame 16 and the base frame 16. That is, since the bearings 86 and 88 and the shafts 94 and 96 for attaching the main set 62 to the base frame 16 are provided at substantially upper and lower ends of the main set 62, the main set 62 is provided at the portion where the through hole 58 is formed. And the adhering strength between the base frame 16 becomes weak, and a gap is likely to occur. Therefore, by providing the ny latch 122 at a position closer to the through hole 58 than the bearings 86 and 88 and the shafts 94 and 96, the fixing strength of the main set 62 to the base frame 16 at the portion where the through hole 58 is formed is effectively improved. It can be secured. As a result, it is possible to reduce the possibility that a piano wire, jig, or the like is inserted from the gap near the through hole 58, and also to reduce the possibility that the piano wire or the jig can be opened with the jig, thereby effectively preventing illegal acts. I can do it.

  Further, particularly in the present embodiment, the ny latch 122 is provided at a position close to the outside of the through hole 58. Thereby, for example, when an illegal act is performed in which a piano wire is inserted, when the piano wire reaches the communication hole 32, the ny latch 122 itself becomes an obstacle, making it difficult to insert the piano wire. Can be. As described above, in the pachinko machine 10 according to the present embodiment, the illegal action can be more effectively prevented by arranging the ny latch 122 at the specific position.

  As mentioned above, although one Embodiment of this invention was explained in full detail, this is an illustration to the last, Comprising: This invention is not limited at all by the specific description in this Embodiment.

  For example, in the pachinko machine 10 described above, a cover that covers the ny latch 122 may be formed in order to prevent the ny latch 122 from being illegally operated from the outside. As such a cover, for example, a box-shaped cover member 126 having an opening 124 on one side as shown in FIG. 11 is preferably used. As shown in FIG. 12, by covering the cover member 126 from the back surface of the nai latch 122, the entire ny latch 122 exposed on the back surface of the frame member 65 can be covered. Thereby, the ny latch 122 can be made inoperable from the outside. In particular, in this embodiment, a thin plate-like hook-like portion 128 is formed at a position spaced apart from the attachment plate portion 127 to which the ny latch 122 is attached in the frame member 65, and these attachment plate portions 127 and The cover member 126 is attached to the frame member 65 by being sandwiched between the shaped portions 128. Thus, the cover member 126 can be easily attached and detached without using any special tool.

  Further, the cover covering the ny latch 122 is not necessarily configured as a separate body from the frame member 65, and may be configured integrally with the frame member 65. For example, since fraudulent acts are often performed from the side of the pachinko machine, as shown in FIG. 13, as shown in FIG. The U-shaped wall portion 130 may be integrally formed to constitute the cover portion. In this way, it is possible to cover only the side surface without covering the back surface of the ny latch 122, and to effectively prevent fraud without hindering the operability from the back surface by, for example, employees of the hall. I can do it.

  Further, the position and number of the pressing means are not limited to the structure as in the above embodiment. For example, it may be provided not only at the outer position of the communication path but also at the inner side, the upper side, the lower side, or the like, or a plurality may be provided.

  Further, the specific structure of the attaching means for detachably attaching the main set 62 to the base frame 16 is not limited at all. For example, in the above-described embodiment, the attachment means is configured by the hinge mechanism including the bearings 86 and 88 and the shafts 94 and 96. However, without using such a hinge mechanism, the attachment holes 98a, The attaching means may be constituted by the ny latches 104, 104, 104, 104 attached to 98b, 98c, 98d. Alternatively, screws or bolts may be used as attachment means.

  In particular, in the pachinko machine 10 according to the above-described embodiment, the upper plate 30 is integrally attached to the front door 18. For example, as a separate body from the front door 18, A dish plate having substantially the same width dimension may be attached to the base frame 16 with a hinge or a screw, and the upper dish 30 may be attached to the dish plate.

  In addition, although not listed one by one, the present invention can be implemented in a mode with various changes, modifications, improvements, and the like based on the knowledge of those skilled in the art. It goes without saying that all are included in the scope of the present invention without departing from the spirit of the invention.

  The technical idea that can be grasped from the above embodiment will be described below.

  Conventionally, a pachinko machine generally has a front frame on which a game board is mounted connected to an outer frame so as to be openable and closable by a shaft attachment means such as a hinge, and a prize is awarded to the back of the front frame. A main set in which a payout passage for guiding a game ball as a ball is formed is attached. And, below the game board in the front frame, a communication path that penetrates in the front and back direction is formed, while the opening on the front side of the communication path is opened to the hitting ball supply tray provided on the surface of the front frame, The opening on the back side of the communication passage is connected to the outlet of the payout passage provided in the main set, so that the game ball guided through the payout passage is guided into the hitting ball supply tray through the communication passage. Yes.

  By the way, the main set is often fixed to the front frame by simple attachment means such as bolts and hinges, and a gap is likely to be formed between the front frame and the main set. There is a case where an illegal act of inserting a pachinko machine into the pachinko machine and converting the winning device provided on the game board into a state where it is easy to win is performed. In particular, the connecting portion between the communication passage and the payout passage is close to the winning device, so that a piano wire or the like is easily inserted.

  In order to deal with such a problem, for example, as disclosed in Patent Document 1, a concave groove is formed around the communication passage formed in the front frame, while the outlet of the discharge passage formed in the main set. It is conceivable to make it difficult for a piano wire or the like to enter by forming a protruding piece around the groove and entering the groove.

  However, the main set is often attached to the front frame at the upper and lower ends. Accordingly, the substantially intermediate portion in the height direction of the main set where the outlet of the payout passage is formed is away from the attachment position to the front frame, so that the fixing strength to the front frame is weak, and it is easy to bend. Therefore, a jig or the like can be easily inserted between the front frame and the main set at the connection portion between the communication passage and the payout passage, and a piano wire or the like can be inserted from the gap formed by the opening. Therefore, the structure as described in Patent Document 1 is still insufficient.

  Here, the technical idea described below has been made in the background as described above, and the problem to be solved is to fix the strength of the main set to the front frame at the site where the communication path is formed. The object is to provide a pachinko machine having a novel structure that can be effectively secured.

  Hereinafter, aspects of the technical idea that can be grasped from the above-described embodiment for solving the above-described problems will be described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  That is, the technical idea (1) that can be grasped from the above embodiment is that the main set having a payout passage is attached to the back surface of the front frame to which the game board is attached and is provided on the front surface of the front frame through the front frame. In the pachinko machine in which the communication path for connecting the hit ball supply tray and the discharge path is formed, the pressing means for pressing the main set against the front frame is positioned closer to the communication path than the mounting means for attaching the main set to the front frame. It is characterized by providing.

  In this way, since the main set is pressed against the front frame by the pressing means, the fixing strength of the main set to the front frame can be effectively ensured. In particular, according to the technical idea (1), the bending of the main set can be effectively suppressed by disposing the pressing means at a position close to the communication path, which is a portion where the main set is easily bent. This makes it difficult to create a gap between the front frame and the main set at the communication passage forming site, and effectively prevents illegal acts such as inserting a jig between the front frame and the main set to pry it open. I can do it.

  In the technical idea (1), the specific structure of the attaching means for attaching the main set to the front frame is not particularly limited, and a conventionally known structure can be appropriately employed. For example, it may be fixed with screws or bolts, or may be detachable without using a tool, for example, by adopting a latch mechanism. Further, the main set does not necessarily have to be removed from the front frame. For example, the main set is hinged to the front frame using a hinge mechanism or the like, and either side of the main set is attached to the front frame. You may make it detachable.

  Moreover, also about the specific aspect of a pressing means, a conventionally well-known structure is employable suitably like the said attachment member. For example, a screw, a bolt, a latch mechanism, or the like can be suitably employed.

  The pressing means is not particularly limited as long as it is arranged at a position closer to the communication path than the arrangement position of the attachment means, but more preferably, at the periphery of the communication path, from the communication path. It is also desirable to be disposed at the outer position. If it does in this way, the pressing means itself between a front frame and a main set can be used as an obstruction at the time of inserting a piano wire, a jig, etc., and an illegal act can be blocked more effectively.

  Moreover, in the technical idea (2) which can be grasped from the above-described embodiment, a mode in which a cover part for covering the pressing means in the main set is provided can be suitably employed.

  According to the technical idea (2), even when jigs are illegally inserted from the outside, the pressing means can be operated from the outside by preventing the jigs from coming into contact with the pressing means at the cover. Thus, the possibility that the fixed state is released can be reduced. In addition, the cover part in this aspect may be provided so that attachment or detachment with respect to a main set may be provided, and may be provided fixedly. Further, the cover portion does not necessarily need to cover the entire pressing means. Therefore, for example, a cover member that surrounds the entire top, bottom, left, right, and back of the pressing means may be formed separately from the main set and attached so as to cover the back of the pressing means, or an improper tool or the like. Since the insertion is often performed from the side surface of the pachinko machine, a wall portion that covers only the side surface of the pressing means may be formed integrally with the main set without covering the back surface of the pressing device. If the cover is formed as such a wall, for example, when an employee of the hall operates the pressing means from the back of the pachinko machine while effectively preventing unauthorized contact such as jigs from the side, It can be operated without removing the cover.
