Description

  The present invention relates to a pachinko gaming machine, and more specifically, a set holding frame is provided with a holding tool and a fixing device, and one end of the game board is held by the holding tool and the other end is fixed by a fixing device. The present invention relates to a pachinko gaming machine in which the game board can be exchangeably set on a set holding frame by supporting.

  In this type of gaming machine represented by a pachinko machine, various gaming machine components are intensively mounted on an inner frame that can be attached to and detached from the outer frame that forms the outer shell of the machine body. . For example, with respect to a game board which is one of the gaming machine components, the game board is set in a state where the game surface is directed to the front side with respect to the set opening of the set holding frame located on the back side of the middle frame. Here, when classifying gaming machines based on the set form of the game board, the type configured to be attached and detached from the front side with the front frame with the glass door open (game board front side attachable / detachable type), It is broadly classified into a type (game board back side detachable type) configured to be attached or detached from the back side while the back mechanism board on the back side of the middle frame opened from the outer frame is opened or removed.

  In any type of gaming machine described above, the gaming board set on the front side of the set holding frame in the set mouth can be housed in a state free of rattling in the set mouth and properly fixed. Is the most important thing. Therefore, for example, provided with a fixing device (engagement holding component) around the inner side of the set port, the game board is assumed to be operated to release or operate each fixing device with respect to the game board set in the set port. There is a strong demand for quick and easy attachment and detachment with simple and easy operation.

  In order to solve these problems, a lock for game board is provided at each of the four corners on the top, bottom, left and right of the set holding frame, and the front frame with the glass door is opened. After the game board is stored and set from the window of the frame in the frame to the set opening of the set holding frame, the operation part of each locking tool is picked with a fingertip, and the locking tool is rotated in a predetermined direction to be displaced to the locking position. There has been proposed a fixing device in which the engaging portion elastically engages with the game board and the game board is elastically fixed and held (see, for example, Patent Document 1). However, according to such a game board support and fixing structure, each end of the game board and the set port must be attached in a state of being aligned from the front side. The pivoting operation to the unlocked position has a difficulty in reducing the work efficiency.

Therefore, for the purpose of further facilitating the replacement work of the game board, the length in the longitudinal direction is set to the longitudinal direction of the game board so as to receive the one edge of the game board in the one side edge of the housing recess in the base. And a stopper formed as a locking member for fixing the game board to the other side edge of the receiving recess. Have been proposed (see, for example, Patent Document 2).
Japanese Patent No. 3051962 JP 2001-327717 A

  However, the above-mentioned holder has a U-shaped groove extending in the vertical direction according to the shape of the game board, so that the side edge of the game board is aligned with the side edge of the game board. Since it must be inserted in a state, there is a troublesome disadvantage. Also, as the game board, display device, and control board increase in size, the overall weight of the game board tends to increase, and the burden on the operator increases if it takes time to insert the side edge of the game board into the receiving port. Difficulties are also pointed out. In particular, in the game board replacement work at the time of model change at a game store, since a large number of game boards must be replaced, simplification thereof is desired. In addition, there is a risk that the receiving opening and the side edge of the gaming board will rub against each other during the replacement work for inserting or removing the gaming board into the receiving opening and causing damage to the gaming board.

And a second restriction surface 78. A pair of hinge pieces 72a and 72a extending outward are integrally bent at both end edges orthogonal to the line where the first restriction surface 76 and the second restriction surface 78 intersect, and the hinge pieces Through holes 72b and 72b that allow the support shaft 73 to be inserted into the holes 72a and 72a are formed on the same axis. Further, the extension dimension of the first restriction surface 76 is set to be shorter than the thickness of the game board D. On the other hand, the extension dimension of the second restricting surface 78 and the width dimension of the restricting member 72 (the extending direction of the line orthogonal to the line where the first restricting surface 76 and the second restricting surface 78 intersect) are: The required dimensions are set so as not to interfere with the game area 31 of the game board D and to effectively hold the side end of the game board D. Further, an end edge 78a of the second restricting surface 78 of the restricting member 72 facing the inside of the set port 13 is bent outward (front side).

(Support shaft)
The through holes 72b, 72b of the hinge pieces 72a, 72a positioned so as to sandwich the bent portions 74a, 74a of the pivot member 74 and the shaft holes 74b, 74b of the bent portions 74a, 74a are aligned. In this state, the support shaft 73 is inserted, and the restriction member 72 is rotatable with respect to the pivot support member 74. The support shaft 73 is a cylindrical member set to have substantially the same dimensions as the through-hole 72b and the shaft hole 74b, and has a latching portion set at one end with a larger diameter than the through-hole 72b and the shaft hole 74b. 73a is formed. The supporting shaft 73 inserted through the holes 72b and 74b has a hooking portion 73a hooked on one hinge piece 72a and a locking piece 75 on the other end protruding from the other hinge piece 72a. The movement in the axial direction is restricted by the fitting.

(Energizing means)
The restricting member 72 is always urged by the urging means 80 toward the direction in which the second restricting surface 78 is separated from the game board support surface 12 a of the set holding frame 12 and the first restricting surface 76.

The biasing means 80 is an elastic member having a required elasticity that is inserted between the pivot member 74 and the regulating member 72. In the first embodiment, the biasing means 80 is a coil spring that is externally attached to the support shaft 73. Is adopted. The biasing means 80 is not limited to a coil spring, and may be another elastic member such as a leaf spring as long as it has a required elasticity.

(Attaching the retainer)
As shown in FIG. 1 or FIG. 2, the holder 70 is disposed such that the support shaft 73 extends in the vertical direction, and the restricting member 72 is always moved by the urging means 80 to the second. The restricting surface 78 is biased in a direction away from the game board support surface 12a of the set holding frame 12, and the restricting member 72 is rotated rearward (toward the game board support surface 12a of the set holding frame 12). Accordingly, the second restriction surface 78 is shifted to a position facing the game board support surface 12a. On the other hand, the first regulating surface 76 always faces the front side (the direction in which the game board D is inserted) by the biasing means 80, and the first regulating surface is rotated as the regulating member 72 is rotated rearward. 76 shifts to a position facing the inner side of the set port 13 (a position facing the side wall surface 12b). When the restricting member 72 is in a normal use state (a state in which the game board D is set on the set holding frame 12), the first restricting surface 76 comes into contact with a side end face of the game board D and the set holding frame 12 The second restricting surface 78 faces the game board support surface 12a while holding the board surface of the game board D. Note that the distance between the opposing second restriction surface 78 and the game board support surface 12a is set to be substantially the same as or slightly shorter than the thickness of the game board D. The board D can be securely clamped.

  Next, the operation of the pachinko gaming machine according to the first embodiment will be described. In the pachinko machine P of the first embodiment configured as described above, the game board D can be easily attached to and detached from the middle frame B by performing necessary operations on the front side of the middle frame B with the glass door opened. Is. Therefore, an attachment / detachment mode of the game board D with respect to the set port 13 and an operation procedure in attachment / detachment will be described.

(Set of holders)
In the pachinko machine P according to the first embodiment, the holders 70 and 70 are disposed at positions that are spaced apart from each other on the one side wall surface 12b of the set holding frame 12 in the vertical direction and are biased upward or downward, respectively. . The restricting member 72 pivotally supported with respect to the pivot member 74 fixed to the side wall surface 12b is urged by the urging means 80 toward the front side which is the insertion direction of the game board D. The space between the second restriction surface 78 and the game board support surface 12a is widely opened, and the first restriction surface 76 faces the front side. First, in a state where the game board D is placed below the set port 13, the second restriction surface 78 of the restriction member 72 in the holder 70 and the game board support surface 12 a of the set holding frame 12. One side end of the game board D is inserted from the opened space. Then, the side end surface of the game board D is brought into contact with the first restriction surface 76 of the restriction member 72, and the game board D is rearward (on the game board support surface 12a side of the set holding frame 12) with the holding tool 70 as a fulcrum. As it rotates, the restricting member 72 rotates with the support shaft 73 as a fulcrum. Then, the game board support surface 12a of the set holding frame 12 abuts on the back surface of the game board D, so that the rotation is restricted, and the game board support surface 12a and the second restriction surface 78 are The game board D is held in a state where one side end portion is sandwiched, and the entire game board D is aligned with the window frame opening 11. Further, the game board D is set with respect to the set port 13 by fixing and supporting the other side end portion of the game board D with a required fixing device H.

  Since the restricting member 72 of the holder 70 is rotatably attached to the pivot member 74 fixed to the side wall surface 12b of the set retaining frame 12, it intersects the L-shape of the restricting member 72. The first restricting surface 76 and the second restricting surface 78 are rotated so as to face the front side which is the insertion side of the game board D, so that the game board support surface 12a of the second holding surface 78 and the set holding frame 12 is provided. A large insertion space for the game board D can be defined between the two. As described above, since the space for inserting the game board D is widened, the game board D can be easily positioned with respect to the holder 70 when the game board D is attached. The possibility of scratches due to rubbing is reduced. Then, with the side end face of the game board D inserted from the insertion space in contact with the first restriction face 76, the restriction board 72 is also integrated by rotating the game board D to the set holding frame 12 side. The game board D is restricted from rotating by coming into contact with the game board support surface 12 a of the set holding frame 12, and the support surface 12 a and the second control surface 78 are connected to the side edges of the game board D. The part is pinched. That is, the game board D is aligned with the window frame opening 11 by rotating with the side end face in contact with the first restriction surface 76 of the holder 70, so that the trouble of positioning the game board D is reduced. Can be reduced. Further, since the side end portion of the game board D is sandwiched between the second restriction surface 78 of the restriction member 72 and the game board support surface 12a of the set holding frame 12, the second restriction surface 78 is attached to the game board D. It is not necessary to have a size that abuts over the entire side end portion, and the holder 70 can be reduced in size and weight can be reduced. Further, by reducing the size of the holder 70, the holder 70 is placed at a position (upper and lower portions) that does not interfere with the guide rail 30 even if the substantially circular guide rail 30 that defines the game area 31 is enlarged. The game area 31 can be widened.

  When the game board D is mounted, the restriction member 72 is in a state where the second restriction surface 78 is separated from the game board support surface 12a in the set holding frame 12 by the biasing means 80. 78 and the game board support surface 12a of the set holding frame 12 can be opened with a wide insertion space for the game board D, and the first restriction surface 76 faces the front surface. The game board D can be inserted and positioned more easily, and the possibility of the game board D being damaged is further reduced.

  Further, since the end edge 78a of the second restricting surface 78 of the restricting member 72 is bent outward, that is, on the side away from the game board support surface 12a of the set holding frame 12, the insertion space is expanded. Thus, there is an advantage that the game board D can be attached more easily. Further, when the game board D is inserted into the insertion space, the edge 78a of the second restriction surface 78 is prevented from hitting the end face of the game board D and being damaged.

  Next, in the pachinko machine P described in the first embodiment, one side end portion of the pair of holding tools 70 provided on the side wall surface 12b of the set holding frame 12 located on the back side of the window frame opening 11 in the middle frame B. A case where the following configuration is adopted as a fixing device for fixing the other side end of the game board D holding the above will be described as a second embodiment. The fixing device H is disposed on each of the inclined wall portions 27 formed at each even angle portion of the set holding frame 12 facing the side wall surface 12b on which the holding tool 70 is disposed. As shown, a holding portion 40 provided on each inclined wall portion 27 and a locking device 55 that is detachably fitted to the holding portion 40 and is rotatably supported. .

It has an engaging portion 41 that can lock the back side of the engagement receiving portion 32 in the stored game board D, and a shaft hole opening portion 42 to which the locking device 55 is attached. The engaging portion 41 includes a circular holding piece 43 positioned on the rear end side of each inclined wall portion 27 and a shaft support portion 44 positioned on the inclined end portion 28 on the front side of the holding piece 43. It is formed in a two-stage connection state. On the rear side of the holding piece 43, a bottomed circular fitting seat portion 45 with respect to the turning support 57 of the locking device 55 is formed. On the other hand, the shaft hole port portion 42 includes a shaft hole 46 extending between the holding piece 43 and the shaft support portion 44 in the front-rear direction of the set port 13, and an inward (inclined end portion) of the set port 13 from the shaft hole 46. 28 is formed in a front U shape by an insertion port 47 that opens in a direction perpendicular to 28, and the locking device 55 is mounted and set on the engaging portion 41 through the insertion port 47.

  In addition, a restricting portion 48 for restricting the unlocking end position of the locking device 55 is integrally formed on the wall portion 27 on the front surface of the oblique wall portion 27. The restricting portion 48 protrudes in an arc shape with the center of the shaft hole mouth portion 42 as a reference, and the guide wall portion 49 and the guide slope 50 with respect to the engaging protrusion 62 formed on the engaging portion 60 of the locking tool 55.
