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 that can be detachably set on a set holding frame by supporting the game board.

  In this type of gaming machine typified 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.

  Further, since the game board is formed of plywood in which thin plates are overlapped, some dimensional errors occur in the thickness direction. That is, if the thickness of the game board is larger than the width of the socket, there is a risk that the side edge of the game board and the socket will be rubbed and damaged during installation, and the game board is inserted into and removed from the socket. Work becomes difficult. On the other hand, if the thickness of the game board is smaller than the width of the receptacle, when the game board is set with respect to the set opening, rattling occurs in the front-rear direction, affecting the movement of the game ball. The problem that gives is pointed out.

  That is, the present invention has been proposed in order to suitably solve these problems inherent in the pachinko gaming machine according to the prior art, and can be easily performed without damaging the game board against the set holding frame.

A recess (D1) is provided on one surface of the game board (D) that is to face the protrusion (12c), and the thickness dimension of the game board (D) in the recess (D1) is Set the same dimension as the distance formed when the second restricting surface (78) is opposed to the protrusion (12c).
The game board (D) is rotated toward the set holding frame (12) in a state where one end face of the game board (D) is pressed against the first restriction surface (76) of the restriction member (72). By doing so, the protrusion (12c) of the set holding frame (12) comes into contact with the recess (D1) of the game board (D), and the second restriction surface is placed on the other surface of the game board (D). (78) is in contact with the game board (D) and is configured to hold the game board (D).

  Further, biasing means (80) for constantly biasing the regulating member (72) in a direction in which the second regulating surface (78) is separated from the flange surface (12a) of the set holding frame (12) is provided. The structure provided may be sufficient.

  Further, the second restricting surface (78) of the restricting member (72) may be formed such that the end edge (78a) is bent outward.

  Furthermore, it is also possible to adopt a configuration in which the holder (70) is provided at a position where it does not interfere with the game area (31) formed on the game board (D).

Before SL securing device (H) is detachably fitted the set holding frame (12) to the opened a set port (13) facing the peripheral holding portion (40), with respect to the holding portion (40) A locking device (55) that is set and rotatably supported;

The operation part (59) capable of rotating operation and the engagement part (60) that can be elastically engaged with the front side of the engagement receiving part (32) of the game board (D) are integrated. The structure to be formed can be adopted .

According to the pachinko gaming machine according to the present invention, since the restricting member of the holder is rotatably attached to the set holding frame, the first restricting surface and the first intersecting L-shape of the restricting member are provided. 2 A wide insertion space can be defined between the second restriction surface and the flange surface of the set holding frame by rotating so that the restriction surface faces the mounting side. That is, since the space for inserting the game board is widened, the positioning of the game board with respect to the holder is facilitated, and the possibility of damage due to the game board sliding against the holder is reduced. Further, the game board is provided with a recess at a required depth from one surface contacting the projection of the set holding frame, and the thickness dimension of the game board in the recess is limited to the projection. Since it is set so as to have the same dimension as the interval formed when the surfaces are opposed, the thickness dimension of the game board from the other surface to the bottom surface of the recessed portion can always be made uniform. Therefore, even if there is a slight error in the thickness of the game board, the thickness of the clamping portion between the second restriction surface and the protrusion is constant, so that it can be suitably fixed and supported. And the recessed portion engage with each other, so that accurate positioning can be achieved. Further, since the end portion of the game board is sandwiched between the second restriction surface of the restriction member and the protrusion of the set holding frame, the dimension is such that the second restriction surface abuts over the entire end portion of the game board. It is not necessary to reduce the size of the holder. Further, by projecting the protrusion at a position spaced inward from the wall surface of the set holding frame by a required distance, a relatively wide space is secured between the recessed portion and the wall surface. 1. With the end face of the game board in contact with the regulation surface, the game board can be easily mounted without interfering with the protrusions when the game board is rotated. Further, by inclining the end face of the protrusion facing the wall surface, the protrusion and the game board do not interfere with each other when the game board is inserted into the holder, and the game board can be scratched. Is reduced.

  When mounting the game board, the restriction member is in a state in which the second restriction surface is separated from the flange surface of the set holding frame by the biasing means, so that the game board can be easily inserted and positioned with respect to the holder. Can be done. Since the edge of the second regulating surface of the regulating member is bent outward, that is, on the side away from the flange surface of the set holding frame, the insertion space can be further expanded to facilitate the mounting operation. There are advantages. Further, when the game board is inserted into the insertion space, the edge of the second restricting surface is prevented from hitting the end face of the game board and being damaged. Furthermore, the game area can be widened by installing the holder at a position that does not interfere with the game area.

Upon detachment of Yu technique board, the locking device in the fixed device, it is possible to form a rotating operation by applying a fingertip to the operation unit, a special rotation operation instrument (tool) without using any Since the game board can be locked and unlocked, in addition to the effects of using the above-mentioned holder, the simple operation of the front of the set holding frame makes it easy and quick to attach and detach the game board. It has a beneficial effect that can be achieved.

  The game board in the pachinko gaming machine is configured to be detachably set on a set holding frame by holding one end side of the pachinko gaming machine with a holding tool and fixing and supporting the other end side with a fixing device. A pivot member attached to the wall surface intersecting the flange surface of the set retaining frame, and a first restriction surface and a second restriction surface which are hinged to the pivot member and pivoted to the retainer and intersect in an L shape. And a regulating member having a surface. Further, a protrusion having a required height is provided on the flange surface, and a recess is provided on one surface of the game board that is scheduled to face the protrusion. The distance is set to be the same as the distance formed when the second restriction surface is opposed to the protrusion. Then, with the one end surface of the game board pressed against the first restriction surface of the restriction member, the game board is rotated toward the set holding frame, so that the protrusion of the set holding frame is a game. The game board is configured to be in contact with the recess of the board and the second regulation surface is in contact with the other surface of the game board to hold the game board.

  Next, preferred embodiments of the pachinko gaming machine according to the present invention will be described below with reference to the accompanying drawings.

That is, the holding device 70 is disposed on the side wall surface 12b proximate to the projecting portion 12c projecting from the flange surface 12a, and when the game board D is attached, the game area of the game board D 31 is provided at a site that does not interfere with 31.

(Pivot member)
As shown in FIG. 3, the pivot member 74 is formed in a U shape in which both end edges of a rectangular plate-like body are bent in the same direction, and bent portions 74 a and 74 a at opposite end edges are formed. The shaft holes 74b and 74b that allow the insertion of a support shaft 73 (described later) that pivotally supports the restricting member 72 are formed on the same axis. In the pivot member 74, a required number of fixing means such as screws inserted to fix the side wall surface 12b of the set holding frame 12 at an intermediate portion sandwiched between the opposed bent portions 74a, 74a ( In the first embodiment, two fixing hole portions 74c are opened. The pivot member 74 has the intermediate portion abutted against the side wall surface 12b of the set holding frame 12 to extend the bent portions 74a and 74a toward the inside of the set port 13, and the The bent portions 74a and 74a are arranged so as to be positioned in a vertical relationship.

(Regulatory member)
The restricting member 72 is formed in an L shape by bending a substantially intermediate portion of a rectangular plate-like body at approximately 90 degrees, and a first restricting surface 76 in which a surface facing inward intersects with the L shape. And a second regulating 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 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: It is set to a required size that does not interfere with the game area 31 of the game board D and that can 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 flange surface 12a of the set holding frame 12, and the first restricting surface 76 is also on the side. It is comprised so that it may space apart from the wall surface 12b. 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. As the restricting surface 78 is urged toward the direction away from the flange surface 12a of the set holding frame 12, the restricting member 72 is rotated rearward (to the flange surface 12a side of the set holding frame 12). The 2nd control surface 78 changes to the position which opposes the flange surface 12a. On the other hand, the first restricting 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 restricting member 72 is rotated rearward as the first restricting surface 72 is rotated. The surface 76 is shifted to a position facing the inside 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 protrusion 12c while holding the board surface side of the recessed portion D1 of the game board D. Note that the distance between the opposing second regulating surface 78 and the projecting portion 12c is set to be substantially the same as or slightly shorter than the thickness from the bottom of the recessed portion D1 to the board surface of the game board D. , 12c so that the game 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, for the attachment and detachment of the game board D to the middle frame B, necessary operations are performed on the front side of the middle frame B with the front frame provided with the glass door open. It can be done more easily. 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 projecting portions 12c and 12c project at positions that are spaced apart from each other in the vertical direction by a flange surface 12a that forms one side edge of the set port 13 and are displaced upward or downward, respectively. It is installed. Further, holders 70 are disposed on one side wall surface 12b of the set holding frame 12 so as to be spaced apart from each other in the vertical direction and biased upward or downward. That is, the protrusion 12c and the holder 70 are provided on the same side and are arranged close to each other.

  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. In addition, the space between the second restriction surface 78 and the flange surface 12a is widely opened, and the first restriction surface 76 faces the front side. In this state, first, with the game board D placed on the lower portion of the set port 13, the second restriction surface 78 of the restriction member 72 in the holder 70, the flange surface 12 a of the set holding frame 12, One side end of the game board D is inserted from the space opened between the two. As a result, the side end face 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 rotated rearward (to the flange surface 12a side of the set holding frame 12) with the holding tool 70 as a fulcrum. As it is moved, the restricting member 72 rotates about the support shaft 73 as a fulcrum. Then, the protrusion 12c of the set holding frame 12 enters the recessed portion D1 formed in the back surface of the game board D and comes into contact with the bottom surface of the recessed portion D1, thereby restricting the rotation. The projecting portion 12c and the second restricting surface 78 are held in a state where one side end portion of the game board D 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 second restricting surface 78 and the flange surface 12a of the set holding frame 12 are A wide insertion space for the game board D can be defined between them. 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 contacting the projection 12c of the set holding frame 12, and the side edge of the game board D is defined by the projection 12c and the second regulation surface 78. It 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. Also, 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 protrusion 12c of the set holding frame 12, the second restriction surface 78 is connected to the side edge of the game board D. It is not necessary to have a size that makes contact over the entire surface of the 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.

  The game board D is provided with a recess D1 at a required depth from the back surface that contacts the protrusion 12c of the set holding frame 12, and the thickness dimension of the game board D in the recess D1 is determined by the protrusion 12c. Is set to have the same dimension as the interval formed when the second restricting surface 78 is opposed to each other, so that the thickness dimension from the board surface of the game board D to the bottom surface of the recess D1 can always be made uniform. it can. That is, the game board is provided by cutting the back surface of the game board D that is to face the protrusion 12c in accordance with the distance from the second restriction surface 78 of the holder 70 that faces the protrusion 12c. The thickness dimension from the board surface of D to the bottom surface of the recessed part D1 is always made uniform.
