  2. Description of the Related Art Conventionally, there is known a pachinko machine configured such that a game board can be detachably attached to a game machine main body by a turning operation from the front side (Patent Document 1).

In the pachinko machine of Patent Document 1, a pair of connectors that are positioned opposite to each other on the back side of the gaming board side and the front side of the gaming machine main body and can be electrically connected or disconnected in accordance with the attaching / detaching operation of the gaming board are arranged. In addition, by using at least one of the connectors as a floating connector that can move in a plane perpendicular to the connection direction, both connectors can be securely connected even when the game board is shifted up and down or left and right during the attachment / detachment operation. It is proposing a technology that can be connected to.
Japanese Patent Laying-Open No. 2005-168679 (0019, FIGS. 3 and 9)

  However, since the operation of mounting the gaming board on the gaming machine main body in Patent Document 1 is based on a turning operation with the opposite side of the connector mounting position as a fulcrum, the connectors first contact each other at an angle. Initially, a load is applied to the connector pin, which may be difficult to insert or may be damaged in some cases.

  Therefore, in the present application, in the gaming machine configured so that the gaming board can be detachably attached to the gaming machine main body from the front side, an insertion / removal operation of the connector set attached to the gaming board and the middle frame is performed. An object of the present invention is to prevent damage to the connector by smoothly executing.

The gaming machine of the present invention made to achieve the above object is:
(1) A holder that is attached to any of the upper, lower, left, and right frame portions of the middle frame and holds one of the upper and lower sides or the left and right sides of the game board in a rotatable manner.
(2) A game board that is attached to a frame portion of the middle frame that is opposite to the frame portion to which the holder is attached and that holds one of the upper, lower, left, or right sides by the holder is rotated toward the middle frame. A fixing device that fixes and supports the other side of the top and bottom or left and right when moved;
(3) a game board side connector attached to a position away from the center of rotation of the back surface of the game board by a predetermined distance outward;
(4) It is attached to the front side of the middle frame and comprises a middle frame side connector that is inserted into and removed from the game board side connector in accordance with the turning operation, and further adopts the following configuration. A gaming machine.
(11) The middle frame side connector and the game board side connector each have a connection portion in which a large number of terminals are arranged in a single row or in a plurality of rows, and the connection to each mounting surface of the middle frame and the game board. It is attached so that the arrangement direction of a large number of terminals in the section is substantially parallel to the upper and lower or left and right sides of the middle frame.
(12) At least one of the middle frame side connector and the game board side connector is attached with the following configuration.
(12a) The connector is attached to the attachment surface in a floating state capable of at least moving in a direction orthogonal to the attachment surface and tilting in a direction along the attachment surface.
(12b) Between the back surface of the connector and the mounting surface thereof, an outer regulating member that regulates the tiltable angle to the outside of the gaming machine to be smaller than the tiltable angle to the inside of the gaming machine is interposed. thing.

  According to the gaming machine of the present invention, at least one connector is mounted in a floating state capable of three-dimensional movement / tilting with respect to the mounting surface (12a) and tilted outward with respect to the game board rotation center. By interposing an outer restricting member that restricts the angle to be smaller than the inward tilt angle (12b), a structure that is easy to tilt inward while allowing three-dimensional movement and tilting. It has been realized. Therefore, when the connectors come into contact and engage with each other as the game board is rotated, the connectors can be smoothly tilted in the direction in which the connectors are engaged with each other as the rotation operation proceeds. Is smoothly executed. Further, when the game board is rotated in the direction of removing the game board, smooth detachment without applying excessive force is realized. Therefore, according to the present invention, the connector can be smoothly inserted and removed simultaneously with the turning operation for attaching and detaching the game board, and the connector can be prevented from being damaged. The relationship between the configurations of (11) and (12) is as follows: “(a) When the middle frame is rotated in the left-right direction, the arrangement direction of the connector terminals is the left-right direction”, “(b) Left-right direction. "When the middle frame is rotated, the connector terminal arrangement direction is the vertical direction", "(c) When the middle frame is rotated in the vertical direction, the connector terminal arrangement direction is the vertical direction" "Or" (d) When the middle frame is rotated in the vertical direction, the connector terminals are arranged in the left-right direction. " In addition, “moving in the direction perpendicular to the mounting surface” in the floating state means “moving the middle frame in the front-rear direction”, and “tilting in the direction along the mounting surface” means “up and down or left-right direction”. It can be rephrased as “tilting”. In this case, the tilting direction is the left-right direction when the rotation center is the left or right frame part, and the vertical direction when the rotation center is either the upper or lower frame part.

Here, the gaming machine of the present invention may further adopt the following configuration.
(21) Both the connectors are constituted by a connector having a box structure in which one is a socket type housing and the other is a plug type housing.
(22) The mounting in the floating state is inserted through through holes formed in the mounting bases formed at the bottom of the box so as to protrude outward from both ends of the terminal row of the connector. It is made up of a mounting screw member and a coil spring that is externally attached to each mounting screw member.
(23) As the outer regulating member, by a protrusion integrally formed on the mounting surface of the connector so as to come into contact with the back surface near the edge on the side far from the game board rotation center of the connector mounted in the floating state. Make up.

  By adopting the above configuration as well, both connectors are securely and reliably connected by fitting the socket (female) and the plug (male). In addition, while using a general-purpose connector of this type of box structure, it is possible to easily and reliably realize a mechanism that allows three-dimensional movement and tilting and that is easily tilted inward by an outer regulating member. Can do.

The gaming machine of the present invention may further adopt the following configuration.
(31) The tip of the connector on the side constituted by the plug type housing is tapered with a taper.

  By adopting this configuration as well, the plug type housing can smoothly enter the socket type housing, and a smoother connection is realized.

  Here, if the fitting part of the plug type housing and the socket type housing is asymmetrical with respect to the center of the terminal row, in addition to the induction at the tip taper, the induction action due to the shape specificity of the fitting part is also demonstrated. Is done. Further, by adopting an asymmetric shape, it becomes impossible to fit when there is an attachment mistake, and it is possible to prevent erroneous connection.

  In the gaming machine of the present invention, “when the connectors are attached so that the terminal rows are aligned in parallel with the upper and lower sides of the middle frame, the outer restricting member is positioned in the vicinity of each attachment screw member of the connector. By interposing in, the inclination angle of the upper part and the lower part at the time of connecting operation of the connector attached in a floating state with a high degree of freedom becomes almost uniform, so that it is difficult for the deviation to occur with respect to the turning direction of the game board, Occurrence of defects such as biting can be more reliably prevented. In this case, the “inner side restricting member is integrally formed on the mounting surface to which the connector is attached as a protrusion extending between positions near the mounting screw members of the connector”, and the inclined state of the connector and the game It is possible to reliably realize a function that makes it difficult to cause the deviation of the rotation state of the board.

The gaming machine of the present invention may further adopt the following configuration.
(41) An inner regulating member configured in a protruding shape having a height lower than that of the outer regulating member is interposed on the back side near the edge near the game board rotation center of the connector mounted in the floating state. That.

By adopting such a configuration as well, it is possible to prevent the inward inclination angle from becoming too large, and to achieve a balance between a large degree of freedom and sufficient regulation. In particular, by adopting the following configuration as well, it is possible to easily adjust the balance of the inclination angle by exchanging parts.
(51) The inner regulating member is configured as a pin-like component that is fitted into a fitting surface to which the connector is attached or a fitting hole formed on the back surface of the connector.

  Note that the gaming machine of the present invention has a bellows type terminal (a terminal provided with a spring property by bending a thin plate) by “(61) using a pair of bellows contact type connectors as the connector”. Due to the spring elasticity, a firm engagement can be achieved even with a loose socket and plug. In this case, “the male and female terminals have a bellows type” can be used. By using a bellows type for both males and females, the terminals themselves can be provided with a function of absorbing displacement with respect to the terminal rows.

  In the gaming machine of the present invention, a pin contact type connector can also be used. In that case, “(71) As the connector, use a pair of pin contact type connectors in which the middle frame side connector is constituted by a plug type housing and the game board side connector is constituted by a socket type housing.” It is good to do. In the pin contact type connector, the plug type housing side is constituted by a hole row, and the socket type housing side is constituted by a pin row. Therefore, by adopting a plug type housing that is less likely to be damaged as the middle frame side connector, even if a pin contact type connector is adopted for a gaming machine installation configuration in which a game board may be replaced at any time. Therefore, it is possible to provide a gaming machine that is less wasteful and better matches the gaming machine installation mode.

  According to the present invention, in a gaming machine configured so that the gaming board can be detachably attached to the gaming machine main body by a turning operation from the front side, the connector set attached to the gaming board and the middle frame is inserted and removed. The operation can be performed smoothly and damage to the connector can be prevented. Therefore, it is possible to easily and reliably carry out the game machine assembly work at the game machine manufacturer and the game board replacement work at the game hall.

  Hereinafter, a pachinko machine according to an embodiment of the present invention will be described in detail with reference to the drawings. In this embodiment, “left” or “right” indicates “left” or “right” when viewed from the front side (front side) of the pachinko machine.

  As shown in FIGS. 1 and 2, the pachinko machine P according to the embodiment has a middle frame B attached to the front side of the opening of the outer frame A so as to be detachable and openable, and a game board D on the front side of the middle frame B. The front frame (glass door, not shown) for seeing through and protecting the front surface of the game board D is attached to the middle frame B so as to be openable and closable. Note that an upper ball tray E, a lower ball tray F, and a firing handle G are attached to the lower part of the front side of the middle frame B.

  A holder J for rotatably holding the left side DL of the game board D is attached to the left side frame portion BL of the middle frame B. This holding jig J is an L-shaped metal fitting that is pivotably attached to the left side frame portion BL of the middle frame B. The game board D is in contact with its left side DL and front surface DF. Hold.

  Also attached to the right side frame portion BR of the middle frame B is a fixing device H for fixing and supporting the right side DR side when the game board D held by the holder J is rotated toward the middle frame B. It has been. The fixing device H includes a rotation operation member H1 that presses and fixes the upper right corner portion DR1 and the lower right corner portion DR2 of the game board D from the front surface.

  Further, as shown in FIG. 2, a game board-side connector 10 is attached to the back surface of the game board D at a position near the right side DR that is separated from the left side DL, which is the center of rotation, by a predetermined distance L1. . On the front side of the middle frame B, a middle frame side connector 20 that is inserted into and removed from the game board side connector 10 is attached at a position separated from the rotation axis of the holder J by a predetermined distance L2 (≈L1). ing.

  As shown in FIG. 1, the middle frame side connector 20 and the game board side connector 10 are attached so that the arrangement direction of the terminals Pin is substantially parallel to the left and right sides of the middle frame.

  In the present embodiment, as shown in FIG. 3, a pair of pin contact type connectors in which the middle frame side connector 20 is constituted by a plug type housing 21 and the game board side connector 10 is constituted by a socket type housing 11 are used. .

  Here, as shown in FIG. 3, the middle frame side connector 20 is formed on each of the mounting base portions 22 formed on the bottom of the box so as to protrude outward from both ends of the terminals Pin in the arrangement direction. The screw 24 inserted through the through hole 23, the nut 25 screwed with the screw 24, and the coil spring 26 externally inserted into each screw 24 move in the direction perpendicular to the middle frame B (front-rear direction) and the middle frame B It is attached in a floating state that can tilt in the left-right direction.

  Further, a screw insertion hole 31 through which the screw 24 is inserted is opened on the surface of the middle frame B to which the middle frame connector 20 is attached, and a protrusion 32 is integrally formed on the right side of the screw hole 31. Yes. The protrusion 32 is a straight line extending between the screw insertion holes 31-31, and the amount of deviation from the screw insertion hole 31 to the right side is slightly smaller than ½ of the back surface width of the middle frame connector 20. It is said that. Therefore, in the attached state, the middle frame side connector 20 is in a floating state in which the outward tilt is restricted.

  Further, the plug-type middle frame side connector 20 has a tip 20a tapered with a taper, and the socket-type game board side connector 10 has a recess tip 10a with a taper. . Also, left and right asymmetrical irregularities are formed on the left and right fitting surfaces of both connectors.

  In the present embodiment, the game board side connector 10 is directly attached to the back surface of the game board D.

  Next, the operation when the game board D is attached to the middle frame B in the pachinko machine P will be described. The left side DL of the game board D is held by the holder J, and the game board D is pressed against the middle frame B by a turning operation. At this time, the game board side connector 10 and the middle frame side connector 20 attached to the back surface of the game board D are engaged with each other. At this time, as the turning operation of the game board D proceeds, the middle frame side connector 20 is guided and regulated so that it is easy to incline inward and hardly inclines outward. Therefore, the inclination in the direction in which the middle frame side connector 20 escapes from the game board side connector 10 is restricted, the inclination in the direction in which the middle frame side connector 20 engages is promoted, and the engagement of the connector set is executed smoothly. When the game board D is pressed against the middle frame B in this way, the rotation operation member H1 of the fixing device H provided in the middle frame B is operated to press and hold the front surface of the game board D.

  It should be noted that when the game board D is rotated in the direction of detaching, smooth detachment without applying excessive force is realized.

  Therefore, according to the pachinko machine P of this embodiment, the connectors 10 and 20 can be smoothly inserted and removed simultaneously with the turning operation for attaching and detaching the game board D, and the connectors 10 and 20 are prevented from being damaged. can do.

  Moreover, since the combination of the socket (female) and the plug (male) is adopted as both the connectors 10 and 20, they are securely and securely connected by fitting. Further, the tip of the middle frame side connector 20 constituted by the plug type housing has a tapered shape with a taper, and the recess tip of the game board side connector 10 has a tapered shape with a taper, so that the plug smoothly into the socket. And can be connected more smoothly. In addition, when the detachment is performed, a relief by the tip taper acts, and a smooth detachment without applying an excessive force is possible.

  Further, since the protrusion 32 extending between the positions near the screw insertion holes 31 and 31 is integrally formed on the connector mounting surface of the middle frame B, it is difficult to cause a deviation between the inclined state of the connector 20 and the rotational state of the game board D. The function to perform is surely realized.

  Next, a second embodiment will be described. The pachinko machine of the second embodiment has the same configuration as that of the above-described embodiment except that the connector is a bellows contact type. Here, the bellows contact type connector is any of the terminals of male and female connectors, as disclosed in JP-A-2006-66352, JP-A-2002-367694, JP-A-2000-260509, and the like. One of them is a contact having a spring property formed by bending a thin plate into a U-shape or the like.

  In the present embodiment, as shown in FIG. 4, a bellows contact obtained by bending a thin plate is used for the female terminal 41, and the connectors 40 and 50 using flat and straight contacts are used for the male terminal 51.

  In the present embodiment, a plug-type connector 40 is attached to the middle frame B side, and a socket-type connector 50 is attached to the game board D side. Both connectors 40 and 50 are inserted into through holes (not shown) formed in respective mounting bases (not shown) formed so as to protrude upward and downward, as in the first embodiment. The screws 44, 54, the nuts 45, 55 screwed with the screws 44, 54, and the coil springs 46, 56 externally attached to the screws 44, 54 are moved in the direction orthogonal to the mounting surfaces and left and right along the mounting surfaces. It is mounted in a floating state that can tilt in the direction.

  In addition, screw insertion holes (not shown) through which screws 44 and 54 are inserted are opened on the back surface of the game board D and the connector mounting surfaces on the front surface of the middle frame B, and the ridges 48 and 48 are formed on the right side of the screw holes. 58 is integrally formed. The protrusions 48 and 58 are linear across the screw insertion holes, and the amount of deviation from the screw insertion holes to the outside (right) is slightly smaller than ½ of the back surface width of the connectors 40 and 50. It is said to be a quantity. Accordingly, in the attached state, the connectors 40 and 50 are in a floating state in which the outward tilt is restricted.

  Furthermore, the tip 40a of the plug-type connector 40 has a tapered shape with a taper, and the tip 50a of the recess of the socket-type connector 50 has a tapered shape with a taper. Further, the upper and lower fitting surfaces of both connectors are formed with asymmetric top and bottom asperities.

  Similarly to the first embodiment, the pachinko machine P of the present embodiment can smoothly insert and remove the connectors 40 and 50 simultaneously with the turning operation for attaching and detaching the game board D. Damage can be prevented. In addition, by using the bellows contact type terminal, it is possible to realize a firm engagement state even as a loose socket & plug.

  Next, a third embodiment will be described. As shown in FIG. 5, the third embodiment has a fitting hole 71 formed on the back side near the edge near the game board rotation center of the connector 10 attached in a floating state in the first embodiment. A pin-like protrusion 72 having a height lower than that of the protrusion 32 is detachably mounted.

  By adopting such a configuration as well, it is possible to prevent the inward inclination angle from becoming too large, and to achieve a balance between a large degree of freedom and sufficient regulation. In particular, since the pin-shaped protrusion 72 is a detachable pin-shaped component, the balance of the inclination angle can be easily adjusted by replacing the component.

  When the connector mounting position is 400 mm from the left side (rotation center) of the game board (full width 480 mm), a comparison is made between the case where both conventional connectors are directly attached and the case where the mounting method of the first embodiment of the present invention is adopted. consider.

  In the conventional mounting method, the deviation between the axis lines of both connectors at the start of insertion (in the direction perpendicular to the mounting surface) is about 3 degrees in angle, and it can be inserted somehow. As in the first embodiment, when mounting using a coil spring and a ridge so as to be in a “floating state in which tilting to the outside is restricted”, the deviation between the axes of both connectors at the start of insertion is about an angle. It was about 2 degrees and could be inserted very smoothly.

  Next, with respect to the case where the connector mounting position is 300 mm (position less than 2/3 of the full width) from the left side (rotation center) of the game board (full width 480 mm), The case where the mounting method of the first embodiment is adopted will be compared.

  In the conventional mounting method, the shift between the axes of the connectors at the start of insertion is about 5 degrees in angle, and the insertion is impossible. On the other hand, the middle frame side connector is “outward” as in the first embodiment. When mounting using coil springs and ridges so as to be in a “floating state where the tilting is restricted,” the misalignment between the axes of both connectors at the start of insertion is within about 3 degrees in angle and can be inserted. It was possible to be in a state.

  As described above, the present invention exhibits the action and effect that the connector can be connected by the turning operation for mounting the game board even when the connector mounting position is close to the center of the game board. You can also. That is, according to the present invention, even if the connector is arranged closer to the center of the game board, the connection can be performed by a turning operation for attaching the game board, thereby increasing the degree of freedom of the connector arrangement position, It can be said that the degree of freedom of arrangement of devices for wiring is increased and the effect of enabling efficient design is also exhibited.

  Even when the second embodiment and the third embodiment are attached, similarly to the above-described example, the game board can be rotated even when the connector is arranged at a position near the center that cannot be inserted by the conventional attachment method. The connector connection state can be completed by a dynamic operation.

  As mentioned above, although several embodiment and one Example were demonstrated as the best form for implementing this invention, this invention is not limited to this, Various within the range which does not deviate from the summary. It can be changed.

  For example, a bellows contact may be used not only on the female side but also on the male side using a connector using the bellows contact.

  Further, the present invention may be implemented for a pachinko machine that attaches and detaches the game board by the vertical rotation method, instead of the configuration in which the game board is attached and detached by the left and right rotation method. In this case, the connector mounting direction may be such that the terminal arrangement direction is along the upper and lower sides of the middle frame. Even when the game board is attached and detached by the left-right rotation method as in the above-described embodiment, the connector may be attached so that the terminal arrangement direction is parallel to the upper and lower sides instead of the left and right sides. Further, the attachment position of the connector may be near the center of the middle frame.

It is a front view of the pachinko machine of an embodiment. It is a cross-sectional view of the pachinko machine of the embodiment. The part of the connector in 1st Embodiment is shown, (A) is the longitudinal cross-sectional view seen from the left, (B), (C) is the cross-sectional view. It is a transverse cross section of the portion of a connector in a 2nd embodiment. It is a transverse cross section of the portion of a connector in a 3rd embodiment.
