Description

  The present invention relates to a gaming machine technique, and more particularly to a technique for positioning a component member constituting a gaming machine at a predetermined attachment position set to another component member.

2. Description of the Related Art Conventionally, in a gaming machine, when a constituent member constituting a gaming machine is attached, a technique for positioning the constituent member at a predetermined attachment position set to another constituent member and then fixing the constituent member is known. Yes. For example, as described in Patent Document 1.
In Patent Document 1, in a pachinko gaming machine (hereinafter referred to as a gaming machine), a winning ball back cage (hereinafter referred to as a back cage), which is a constituent member of the gaming machine, is composed of other components. A technique is described in which, when attached to a certain game board, the back cover is positioned at a predetermined attachment position set on the game board and then fixed.

Specifically, in the gaming machine, a positioning projection protrudes from the back cage, while a positioning projection is provided on the back surface of a pachinko game board (hereinafter referred to as a game board) to which the back cage is attached. A positioning hole for inserting a hole is formed at a predetermined mounting position.
The positioning protrusion protrudes in a substantially frustoconical shape from the back bowl body toward the game board side, and the outer diameter of the positioning projection on the tip side (game board side) is larger than the outer diameter of the root side (back bowl body side) Is also formed small. On the other hand, the positioning hole is formed such that the inner diameter of the positioning hole is larger than the outer diameter on the distal end side of the positioning protrusion and smaller than the outer diameter on the root side of the positioning protrusion.

  With such a configuration, positioning of the back paddle to a predetermined mounting position set on the game board, which is performed when the back paddle is attached to the game board, the positioning protrusion of the back pad is used for the game board. This is done by inserting it into the positioning hole. And since the outer diameter of the positioning projection at the base side is larger than the inner diameter of the positioning hole, the positioning projection inserted into the positioning hole has an outer peripheral wall of the positioning projection at the periphery of the opening of the positioning hole. It is held in contact. That is, since the positioning projection does not rattle with respect to the positioning hole, the back hook can be accurately positioned at a predetermined mounting position set on the game board.

However, in the technique described in Patent Document 1, the positioning of the back saddle (component) to the predetermined mounting position set on the game board (other component) has not been sufficiently accurate.
Specifically, in such a technique, since the outer diameter of the positioning projection at the base side is larger than the inner diameter of the positioning hole, when inserting the positioning projection into the positioning hole, the positioning projection and the positioning hole It was necessary to push in the positioning protrusion so as to crush at least one of the above. Therefore, if the positioning protrusion is not sufficiently pushed, the positioning protrusion is not sufficiently inserted into the positioning hole, the positioning protrusion floats from the positioning hole, and the back cover is set to a predetermined position set on the game board. There was a problem that it could not be positioned accurately at the mounting position.
Further, when the positioning protrusion is sufficiently inserted (pushed) into the positioning hole, at least one of the positioning protrusion and the positioning hole may be crushed. In such a case, there has been a problem that the shape of the positioning protrusion and the positioning hole (in other words, the shape of the gaming machine) is deformed so that it cannot be restored.

  The present invention has been made in view of the above-described problems, and the problem to be solved is that the constituent members constituting the gaming machine are not modified so that the shape cannot be restored. It is an object of the present invention to provide a gaming machine that can be accurately positioned at a predetermined mounting position set on a member.

When the center accessory 58 is attached to the game board 50, it is positioned at a predetermined attachment position set on the game board 50, and then fixed using screws 66. The center accessory 58 is provided with a positioning projection 70 for positioning at a predetermined mounting position set on the game board 50 (see FIG. 3).
The center accessory 58 is an embodiment of the “first constituent member” according to the present invention, and is not limited to this. That is, the “first constituent member” may be a member constituting the “game machine” according to the present invention.

  Next, with reference to FIGS. 3 to 8, positioning of the center accessory 58 at a predetermined attachment position set in the game board 50 performed when the center accessory 58 is attached to the game board 50 will be described. To do.

The positioning of the center accessory 58 at a predetermined attachment position set in the game board 50, which is performed when the center accessory 58 is attached to the game board 50, will be described later. This is done by inserting into the positioning hole 80 of the game board 50.
Below, the structure of the positioning protrusion 70 of the center accessory 58 and the positioning hole 80 of the game board 50 is demonstrated in detail.

First, the structure of the positioning projection 70 of the center accessory 58 will be described with reference to FIGS. 3 and 4.
The positioning protrusion 70 is an embodiment of the “protrusion” according to the present invention.

The positioning protrusion 70 is for insertion into the positioning hole 80 of the game board 50. The positioning protrusion 70 protrudes from the rear end surface of the center accessory 58 toward the rear (the game board 50 side).
The positioning protrusion 70 includes an insertion portion 71, a pedestal portion 72, and a slit portion 73.

The insertion portion 71 is an embodiment of the “insertion portion” according to the present invention. As shown in FIG. 3B, the insertion portion 71 is disposed substantially at the rear portion (tip portion) of the positioning projection 70. The insertion portion 71 has a substantially cylindrical shape, and is formed in a tapered shape as it goes from one end side (base side) to the other end side (tip side). The insertion portion 71 is disposed with the distal end side formed in a tapered shape facing rearward and the axial center direction of the insertion portion 71 as the protruding direction of the positioning projection 70, that is, the front-rear direction.
In addition, in this embodiment, although the insertion part 71 is formed in the substantially cylindrical shape, it is not limited to this structure. That is, the insertion portion 71 may be formed in a tapered shape as it goes from one end side (base side) to the other end side (tip side). For example, the insertion portion 71 is formed in a substantially quadrangular prism shape, a substantially triangular prism shape, or the like. obtain.

  The pedestal 72 is an embodiment of the “pedestal” according to the present invention. As shown in FIG. 3B, the pedestal portion 72 is disposed substantially at the front portion (root portion) of the positioning protrusion 70 and is connected to the front end side (root side) of the insertion portion 71. That is, the pedestal portion 72 is formed at the rear end portion of the pedestal portion 72 so as to be continuous with the insertion portion 71 and is disposed in front of and behind the insertion portion 71. Further, the pedestal portion 72 is formed at the front end portion thereof so as to continue to the center accessory 58 main body (more specifically, the rear end face of the center accessory 58). The pedestal portion 72 is formed in a substantially cylindrical shape, and is arranged with the axial direction as the protruding direction of the positioning projection 70, that is, the front-rear direction. The axis of the pedestal 72 is disposed on an extension line ahead of the axis of the insertion portion 71.

  The pedestal portion 72 is formed in a substantially cylindrical shape and has an outer shape that is recessed inwardly from the outer shape of the front end portion (root portion) of the insertion portion 71. Specifically, the pedestal portion 72 is formed so that the maximum outer diameter (reference symbol W2 in FIG. 3) of the pedestal portion 72 is smaller than the outer diameter of the front end portion of the insertion portion 71 (reference symbol W1 in FIG. 3). The Therefore, as shown in FIG. 3A, the pedestal portion 72 is accommodated within the projection area of the insertion portion 71 in a rear view.

The slit portion 73 is an embodiment of the “slit portion” according to the present invention. As shown in FIG. 3, the slit portion 73 is a cutting region that divides the positioning projection 70 in the radial direction. As shown in FIG. 3A, the slit portion 73 is formed in a substantially cross shape in the rear view, and the positioning projection 70 is divided into four in the radial direction. That is, the slit portion 73 is constituted by two linear grooves extending in the radial direction through the substantially cylindrical center of the positioning protrusion 70, and the two grooves are orthogonal to each other.
In the following, as shown in FIG. 3A, each of the four portions of the insertion portion 71 is referred to as an “insertion division portion 71a”. Although the size of each insertion division part 71a is not specifically limited, it is desirable that each is the same. Moreover, the slit part 73 is not limited to the structure formed in a substantially cross shape by back view. In other words, the slit portion 73 is formed in a substantially single shape when viewed from the back, for example, and the positioning projection 70 is divided into a plurality of portions in the radial direction, such as a configuration in which the positioning projection 70 is divided into two in the radial direction. I just need it.

  The slit portion 73 is formed from the rear end portion (front end portion) of the insertion portion 71 to at least a part of the rear end portion side (front end portion side) of the pedestal portion 72 in plan view. That is, the slit portion 73 extends forward from the rear end portion of the positioning projection 70, and the front end portion (reference numeral P <b> 1 in FIG. 3) of the slit portion 73 is the rear end portion (reference number in FIG. 3). It is formed so as to be located in front of P2). The front end portion P1 of the slit portion 73 only needs to be positioned in front of the rear end portion P2 of the pedestal portion 72. For example, the front end portion P1 of the pedestal portion 72 in the front-rear direction in plan view with the front end portion (reference numeral P3 in FIG. The slit may be formed so as to be located at the same location, and the slit 73 may be formed over the entire front and rear direction of the pedestal 72. In the following, in the pedestal portion 72, as shown in FIG. 3, a portion between the rear end portion P2 of the pedestal portion 72 and the front end portion P1 of the slit portion 73 is referred to as an “elastic deformation portion 72a”.

With such a configuration, in the positioning projection 70, the elastic deformation portion 72a of the pedestal portion 72 is connected to the other portion of the pedestal portion 72 (the front side of the elastic deformation portion 72a, that is, the front end of the slit portion 73 in the pedestal portion 72). Compared with each insertion division | segmentation part 71a), the thickness of radial direction is formed thinly, and it is comprised so that elastic deformation can be carried out to the said radial direction. Therefore, as shown in FIG. 4, when each insertion division 71a is pressed toward the inner diameter direction, the elastic deformation portion 72a connected to the front end side of each insertion division 71a is moved in the pressing direction (inner diameter direction). ), And each of the inserting and dividing portions 71a moves in the pressing direction (inner diameter direction). That is, as shown in FIG. 4A, each insertion division part 71 a moves so that the width of the slit part 73 with the insertion division part 71 a adjacent in the vertical and horizontal directions becomes narrow, and the insertion part 71. Is deformed so that the maximum outer diameter after pressing (reference numeral W10 in FIG. 4) is smaller than the maximum outer diameter before pressing (reference numeral W1 in FIG. 4).
In this embodiment, since the insertion portion 71 is formed in a substantially columnar shape, the maximum outer diameter of the insertion portion 71 before pressing is the same as the outer diameter of the front end portion of the insertion portion 71. In the drawings, the same symbol W1 is used.

Next, the positioning hole 80 of the game board 50 will be described with reference to FIG.
The positioning hole 80 is an embodiment of the “insertion hole” according to the present invention.

The positioning hole 80 is configured such that the positioning projection 70 of the center accessory 58 can be inserted therein, and the inserted positioning projection 70 can be extracted.
The positioning hole 80 is formed at a predetermined attachment position of the center accessory 58 set in the game board 50. The positioning hole 80 has a substantially cylindrical shape, and is drilled with the axial center direction directed in the front-rear direction, which is the insertion direction of the positioning projection 70.
In the present embodiment, the positioning hole 80 is drilled in a substantially cylindrical shape, but is not limited to this configuration. That is, the positioning hole 80 can be drilled in, for example, a substantially quadrangular prism shape or a substantially triangular prism shape. Furthermore, although the positioning hole 80 is drilled in a bottomed cylindrical shape, it may be configured to penetrate the game board 50 (see FIG. 9).
In the present embodiment, the positioning hole 80 has a substantially cylindrical shape and is drilled with the axial direction as the front-rear direction. In other words, the inner peripheral wall of the positioning hole 80 extends straight in the front-rear direction, but is not limited to this configuration. That is, the inner peripheral wall of the positioning hole 80 may be configured to increase in diameter as it goes rearward, or may be configured to have a step instead of extending straight.

Further, the positioning hole 80 is formed such that the inner diameter (reference numeral W3 in FIG. 5) of the positioning hole 80 is smaller than the maximum outer diameter W1 of the insertion portion 71 of the positioning protrusion 70. Further, the positioning hole 80 is formed such that the inner diameter W3 of the positioning hole 80 is larger than the maximum outer diameter W2 of the pedestal portion 72 of the positioning projection 70. In addition, when the positioning projection 70 is inserted into the positioning hole 80, the entire pedestal portion 72 is inserted into the positioning hole 80, and the root portion of the insertion portion 71 is formed on the inner peripheral wall of the positioning hole 80. It is comprised so that it may contact | abut.
In the present embodiment, the pedestal 72 is configured such that when the positioning projection 70 is inserted into the positioning hole 80, the entire pedestal 72 is inserted into the positioning hole 80. It is not limited.

  Next, the insertion of the positioning protrusion 70 of the center accessory 58 into the positioning hole 80 of the game board 50 will be described with reference to FIGS.

  As shown in FIG. 6, when the center combination 58 is attached to the game board 50, the center combination 58 is arranged in front of and in a position opposite to a predetermined attachment position set on the game board 50. . That is, the positioning projection 70 of the center accessory 58 is disposed in front of the positioning hole 80 of the game board 50 and at a position where the axis of the positioning projection 70 is on the extension line of the axis of the positioning hole 80. Then, as the center combination 58 moves rearward (game board 50 side), the positioning projection 70 moves rearward (game board 50 side) together with the center combination 58, and the rear end portion of the positioning projection 70 It will be inserted into the positioning hole 80 from the (tip portion).

  However, as described above, the maximum outer diameter W1 of the insertion portion 71 of the positioning projection 70 is formed larger than the inner diameter W3 of the positioning hole 80. Therefore, as shown in FIG. 6, the positioning projection 70 is inserted into the positioning hole 80 while the outer peripheral wall of the insertion portion 71 (each insertion division portion 71a) and the peripheral edge portion of the front end portion of the positioning hole 80 are in contact with each other. Then, the insertion of the positioning projection 70 is once restricted.

  When the positioning projection 70 is further inserted into the positioning hole 80, the outer peripheral wall of the insertion portion 71 (each insertion division portion 71 a) of the positioning projection 70 presses the peripheral edge portion of the front end portion of the positioning hole 80. The reaction force acts on the insertion portion 71 (each insertion division portion 71a). And since the reaction force by the said press acts toward an inner diameter direction, the insertion part 71 (each insertion division | segmentation part 71a) of the positioning protrusion 70 will be pressed toward an inner diameter direction.

  When the insertion portion 71 (each insertion division portion 71a) is pressed toward the inner diameter direction, as described above, the maximum outer diameter W10 after pressing is deformed so as to be smaller than the maximum outer diameter W1 before pressing. (See FIG. 4). Then, as shown in FIG. 7, when the maximum outer diameter W10 after the insertion portion 71 is pressed is deformed so as to be smaller than the inner diameter W3 of the positioning hole 80, the positioning protrusion 70 can be inserted into the positioning hole 80. That is, since the positioning protrusion 70 is formed in a tapered shape as the insertion portion 71 moves from the front end side to the rear end side, the outer peripheral wall of the insertion portion 71 (insertion division portion 71 a) is used as the peripheral edge of the front end portion of the positioning hole 80. In other words, the outer peripheral wall of the insertion portion 71 (each insertion division portion 71a) is deformed so that the outer diameter of the insertion portion 71 is reduced by the reaction force caused by the pressing. It is inserted (pushed in) into the positioning hole 80 while sliding on the peripheral part of the part.

  As shown in FIG. 8A, when the positioning protrusion 70 is inserted into the positioning hole 80 and the rear end surface of the center accessory 58 comes into contact with the front surface of the game board 50, the insertion of the positioning protrusion 70 is completed. In other words, the positioning protrusion 70 is inserted into the positioning hole 80 when the center combination 58 and the game board 50 are brought into contact with each other at a position where they are fixed to each other. Then, the base portion of the insertion portion 71 of the positioning projection 70 is brought into contact with the inner peripheral wall of the positioning hole 80.

As described above, when the positioning projection 80 is inserted into the positioning hole 80, the entire pedestal portion 72 is inserted into the positioning hole 80 in the present embodiment. Note that the base portion of the insertion portion 71 is configured to contact the inner peripheral wall of the positioning hole 80.
With such a configuration, for example, even if the positioning hole 80 does not have the bottomed cylindrical shape in the present embodiment but penetrates the game board 50 as described above, as shown in FIG. A portion (tip portion) of the insertion portion 71 protrudes rearward from the game board 50, but a portion (root portion) of the insertion portion 71 is in contact with the inner peripheral wall of the positioning hole 80. That is, even if the positioning hole 80 is configured to penetrate the game board 50, the entire insertion portion 71 of the positioning protrusion 70 protrudes rearward from the positioning hole 80 (game board 50), and the insertion portion 71 of the positioning protrusion 70. The front end surface of the game board 50 and the rear end surface of the game board 50 do not come into contact with each other (the state in which the inner peripheral wall of the positioning hole 80 is locked to the pedestal portion 72 recessed inward from the insertion portion 71).

  With such a configuration, when the insertion of the positioning protrusion 70 into the positioning hole 80 is completed, the center accessory 58 and the game board 50 are in contact (contact), and a gap is formed between them. Absent. That is, the center accessory 58 can be accurately positioned at a predetermined mounting position set on the game board 50. Further, it is not necessary to push in the positioning projection 70 so as to crush at least one of the positioning projection 70 and the positioning hole 80. That is, it is possible to prevent the shape of the positioning protrusion 70 and the positioning hole 80 (in other words, the shape of the gaming machine 1) from being deformed so as not to be restored.

Further, in the state where the insertion of the positioning protrusion 70 is completed, the positioning protrusion 70 is deformed so that the outer diameter of the insertion portion 71 is small, and the inner peripheral wall of the insertion portion 71 (each insertion division portion 71a) and the positioning hole 80 The peripheral walls are in contact with each other. That is, the restoring force of the elastically deforming portion 72a that is connected to the front end side of each inserting and dividing portion 71a and elastically deforms acts on each inserting and dividing portion 71a, and the outer peripheral wall of each inserting and dividing portion 71a. Will press the inner peripheral wall of the positioning hole 80 toward the outer diameter direction. As a result, it is possible to prevent the positioning protrusion 70 from easily coming out of the positioning hole 80. Further, since the positioning protrusion 70 does not rattle with respect to the positioning hole 80, the center accessory 58 can be accurately positioned at a predetermined mounting position set on the game board 50.
As described above, for example, when the inner peripheral wall of the positioning hole 80 is increased in diameter as it goes rearward, or when it is configured to have a step instead of being straightly extended, positioning is performed. Compared with the case where the inner peripheral wall of the hole 80 extends straight in the front-rear direction, each insertion division 71a that presses the inner peripheral wall of the positioning hole 80 toward the outer diameter direction is extracted forward. Becomes more difficult. That is, in such a case, the positioning protrusion 70 can be further prevented from easily coming out of the positioning hole 80.

  Further, when the restoring force of the elastic deformation portion 72a acts and the outer peripheral wall of each insertion division portion 71a presses the inner peripheral wall of the positioning hole 80 toward the outer diameter direction, more specifically, the insertion portion 71. The peripheral edge portion of the front end portion is in contact with the inner peripheral wall of the positioning hole 80. In other words, as shown in FIG. 8B, the peripheral edge portion of the front end portion (root portion) of the insertion portion 71 is in a so-called “edge standing” state with respect to the inner peripheral wall of the positioning hole 80. Therefore, for example, if the game board 50 in which the positioning hole 80 is formed is formed of an elastically deformable member such as a veneer plate, the peripheral edge portion of the front end portion of the insertion portion 71 is removed by the action of the restoring force. It is pressed toward the radial direction and is recessed (elastically deformed) in the outer diameter direction. That is, the peripheral edge portion of the front end portion of the insertion portion 71 is locked to the inner peripheral wall of the positioning hole 80, and the positioning protrusion 70 can be further prevented from easily coming out of the positioning hole 80.

Even in the state where the insertion of the positioning protrusion 70 is completed, the positioning protrusion 70 (center accessory 58) is not completely fixed to the positioning hole 80 (game board 50). Therefore, the positioning protrusion 70 can be extracted from the positioning hole 80 with an appropriate force. In such a case, as described above, even if the inner peripheral wall of the positioning hole 80 is recessed in the outer diameter direction by the positioning projection 70 (is elastically deformed), the shape can be restored by the restoring force. .
The “appropriate force” is a level of force that can pull out the center accessory 58 by human power without using a tool or the like. Even in such a case, when the center object 58 is fixed to the game board 50 using the screws 66, the positioning protrusions 70 may be rattled with respect to the game board 50. It is assumed that the positioning hole 80 is pushed (contacted) to a certain extent.

  As described above, the gaming machine 1 is a gaming machine including the center accessory 58 (first constituent member) and the game board 50 (second constituent member) fixed to each other, and the center accessory 58 is provided. The (first component) is provided with a positioning projection 70 (projection) that protrudes toward the game board 50 (second component), and the positioning projection 70 (projection) has a tip side to a tip side. An insertion portion 71 that is formed in a tapered shape as it goes to, a pedestal portion 72 that is connected to the base side of the insertion portion 71 and has an outer shape that is recessed inward from the outer shape of the root portion of the insertion portion 71, A slit portion 73 formed from the distal end portion of the insertion portion 71 to at least a part of the pedestal portion 72 and dividing the positioning projection 70 (protrusion) in the radial direction; The two component members) A positioning hole 80 (insertion hole) through which the positioning protrusion 70 (protrusion) of the accessory 58 (first constituent member) can be inserted and from which the inserted positioning protrusion 70 (protrusion) can be extracted is provided, When the center accessory 58 (first constituent member) and the game board 50 (second constituent member) are brought into contact with each other at a fixed position, the positioning protrusion 70 (protrusion) is moved to the positioning hole 80 ( The base portion of the insertion portion 71 of the positioning protrusion 70 (protrusion) is brought into contact with the inner peripheral wall of the positioning hole 80 (insertion hole).

  With such a configuration, the gaming machine 1 does not deform so that the shape of the gaming machine 1 cannot be restored, and the center accessory 58 that is a constituent member (first constituent member) constituting the gaming machine is provided. It can be accurately positioned at a predetermined mounting position set on the game board 50 which is another component member (second component member).
