Description

  The present invention relates to a gaming machine having a built-in voice generating device.

Conventionally, gaming machines represented by pachinko machines, slot machines, and the like have built-in speaker devices as sound generating devices that output various sound effects in games. In the past, such a speaker device had a strong secondary meaning in the game that it only has to be heard, but in recent years, the effect of playing the game by voice has become more important. Therefore, a more realistic sound is output from the stereo device using a plurality of speaker devices, or the speaker device is arranged on the front panel of the gaming machine as close to the ear as possible so that the player has a clearer and better sound quality. I try to hear sound effects.
Furthermore, in recent years, a directional speaker device is not simply disposed on the front panel of the gaming machine, but is further inclined to the player's head direction to achieve further improvement in sound quality. . Thus, the player can experience a more realistic sound effect by improving the arrangement of the speaker device, and the interest of the game is increased.

Incidentally, the speaker device is generally fixed to a predetermined mounting position by screwing. That is, the speaker device is restrained by matching the screw holes on the support portion side with the mounting holes on the speaker device side and screwing the screws. However, in the case where the speaker device is disposed at an angle as described above, it may be difficult to provide a screw hole in the support portion. That is, in general, the support portion that supports the speaker device is a molded part that is integrally formed with another portion, for example, the base plate of the front panel, by plastic molding using a mold in the current gaming machine. In plastic molding using a mold, it is preferable that the number of molds is reduced as much as possible and that a simple slide mold can be removed. That is, it is preferable to divide into two parts by two divided molds A and B as shown in FIG. 16A because the mold can be simplified and the cost can be suppressed, and troubles at the time of die cutting are reduced.
However, when the speaker device is tilted with respect to the reference vertical plane s as shown in FIG. 15 and disposed in the support portion, the screw hole 100 also needs to be tilted according to the tilt. However, in this case, the divided molds A and B may not be used. That is, when the divided molds A and B are slid in the direction of the arrow shown in FIG. 16 (b), the direction of the screw hole 100 (the direction of the hole axis p) is deviated from the direction of mold release. This is because the filled and solidified plastic becomes an obstacle and cannot be removed. In order to avoid this, for example, as shown in FIG. 16 (c), it is necessary to use three divided molds of ABC. However, this makes the die cutting very troublesome and increases the cost of the mold. Further, if the mold shape is complicated, the defective product rate is increased accordingly, which is not preferable. Furthermore, in reality, it is not possible to deal with screw holes with different directions in which three or more split molds are pulled out in this way. Instead, screw holes that are inclined due to the structure of the support part and other configurations are supported by the support part. In some cases, it cannot be formed.

Several measures can be taken to solve these problems. For example, in Patent Document 1, as shown in FIG. 8 of Patent Document 1, the opening shape of the screw lower hole 170 is a long hole along the inclined direction, and the shape in which the upper side of the inner wall surface extends outwardly from the drawing direction of the mold. As a result, the die can be removed and screwed so that the axial direction of the tapping screw 168 is orthogonal to the mounting plate 26 as shown in FIG.
As another means, when the cone-shaped speaker device 102 is arranged parallel to the inclined surface 101 as shown in FIGS. 17 and 18, the hook-like hooks 103 and 104 arranged on the upper and lower sides on the support side are used. The speaker device 102 can be fixed. The overhanging portion 108 on the speaker device 102 side is sandwiched between the support pins 105 and 106 and the hooks 103 and 104 at two upper and lower positions, and is supported in an inclined state.
Japanese Patent Laid-Open No. 2003-180954

However, in Patent Document 1, the screw lower hole 170 into which the tapping screw 168 is screwed has a long hole shape, so that the entire circumference of the tapping screw 168 does not bite into the screw lower hole 170. The tapping screw 168 is merely screwed into the screw lower hole 170 so as to be sandwiched between the front and rear inner peripheral wall surfaces. Therefore, in such a structure, although the die can be removed, the amount of biting in the screw lower hole 170 of the tapping screw 168 is insufficient, and the fastening force may not be sufficiently exhibited.
In addition, in the fixing means of the speaker device 102 shown in FIGS. 17 and 18, the end of the overhanging portion 108 is merely sandwiched between the support pins 105 and 106 and the hooks 103 and 104. Although the fixing force is weak and fixed, the speaker device 102 itself vibrates following the vibration of the cone because it is not firmly fastened like a screw, and the sound emitted is distorted. There is a problem (so-called sound is broken or symptom).
The present invention has been made paying attention to such problems existing in the prior art. The purpose of the game machine is that it can be fixed with screws with a simple structure without using a complicated mold when the sound generator is oriented in the direction of the player and fixed to a molded part. Is to provide.

In order to achieve the above object, according to the first aspect of the present invention, the front part facing the player is provided with a decorative member, and is provided with a molded part formed by molding, and the front part for sealing the internal device from the front. The panel is a molded part, and a support part with an inclined surface is formed by integral molding on the same molded part, and the same sound is generated with respect to the support part with a sound generating device having directivity on the inclined surface. In a gaming machine in which the device is fixed and the sound emitted from the sound generation device is directed toward the front and near the center of the front panel, with respect to the surface perpendicular to the die-cutting direction of the mold of the mold-molded part The inclined surface is configured to be inclined, and the support portion is formed with a through-hole penetrating through the front and back opening to the inclined surface, and the inner peripheral wall surface of the through-hole extends along the die cutting direction. Shape and the sound generator side Forms a threaded hole in which the axial direction coincides with the hole position in a state of being arranged the sound generating device in the same inclined surface perpendicular to the inclined surface direction,
A screw is inserted into the through hole so that the inclined surface and the axial direction are orthogonal to the back surface side of the support portion, and the screw is screwed into the screw hole through the through hole and tightened. The gist of the invention is that the sound generator is held on the inclined surface.

When the sound generator is fixed to the support portion by screwing, the screw hole on the support portion side and the screw hole on the sound generation device side are aligned and screwed. However, when the support portion has an inclined surface and the sound generator is disposed on this inclined surface, the screw hole axis on the support portion side must be aligned with the screw hole on the sound generator side unless it is orthogonal to the inclined surface. I can't. However, in a molded part in which the support part is integrally formed by molding, the die cutting direction may not be matched with the axis direction of the screw hole on the support part side. In such a case, the axis of the screw hole on the support portion side cannot be orthogonal to the inclined surface, and it is difficult to fix the sound generator to such an inclined surface with only screws.
However, according to the first aspect, the inner peripheral wall surface of the through hole formed so as to penetrate through the front and back of the support portion and open to the inclined surface has a shape extending along the die-cutting direction of the molded part. For this reason, it is possible to perform die cutting of the molded part. The through hole allows the screw to advance so that its axis is perpendicular to the inclined surface when the screw is inserted from the back side of the support portion. On the other hand, since the axial direction of the screw hole on the sound generating device side is orthogonal to the inclined surface direction, the through hole and the screw hole can be aligned with the inclined surface of the sound generating device. In other words, it is possible to insert the screw from the back surface side of the through hole so that the screw and the screw hole can be securely screwed together without shifting the axis of the screw. The sound generator is finally held on the inclined surface of the support portion by tightening the screws.
As a result, the molded part can be die-cut and the screw can be advanced from the back surface of the support portion so as to be orthogonal to the inclined surface direction in the axial direction and screwed into the screw hole. Various inclined surfaces can be provided regardless of the direction, and the sound generating device can be firmly fixed only with screws.

  In order to achieve the above object, according to the invention of claim 2, the front part facing the player is provided with a decorative member, and is provided with a molded part formed by molding, and the internal device is sealed from the front. A support part having an inclined surface is formed by integral molding on the same molded part, and the sound generating device having directivity is arranged on the inclined surface. In a gaming machine in which the sound generator is fixed and the sound emitted from the sound generator is directed to the front and near the center of the front panel, the sound generator is placed on a surface perpendicular to the mold release direction of the mold part. On the other hand, the inclined surface is configured to be inclined, and the support portion is formed with a through-hole penetrating the front and back that opens to the inclined surface, and the inner peripheral wall surface of the through-hole is expanded in the front-back direction. The sound generation On the installation side, a screw hole that coincides with the position of the same hole and whose axis direction is orthogonal to the direction of the inclined surface in a state where the sound generating device is arranged on the same inclined surface is formed. A screw is inserted from the rear surface side so that the inclined surface and the axial direction are orthogonal to each other, and the screw is screwed into the screw hole through the through hole, thereby restricting the sound generator to the inclined surface. The gist of this is to stop it.

When the sound generator is fixed to the support portion by screwing, the screw hole on the support portion side and the screw hole on the sound generation device side are aligned and screwed. However, when the support portion has an inclined surface and the sound generator is disposed on this inclined surface, the screw hole axis on the support portion side must be aligned with the screw hole on the sound generator side unless it is orthogonal to the inclined surface. I can't. However, in a molded part in which the support part is integrally formed by molding, the die cutting direction may not be matched with the axis direction of the screw hole on the support part side. In such a case, the axis of the screw hole on the support portion side cannot be orthogonal to the inclined surface, and it is difficult to fix the sound generator to such an inclined surface with only screws.
However, in claim 2, the inner peripheral wall surface of the through hole that is formed through the front and back of the support portion and opens to the inclined surface has a shape that expands in the front and back direction. For this reason, it is possible to perform die cutting of the molded part. The through hole allows the screw to advance so that its axis is perpendicular to the inclined surface when the screw is inserted from the back side of the support portion. On the other hand, since the axial direction of the screw hole on the sound generating device side is orthogonal to the inclined surface direction, the through hole and the screw hole can be aligned with the inclined surface of the sound generating device. In other words, it is possible to insert the screw from the back surface side of the through hole so that the screw and the screw hole can be securely screwed together without shifting the axis of the screw. The sound generator is finally held on the inclined surface of the support portion by tightening the screws.
As a result, the molded part can be die-cut and the screw can be advanced from the back surface of the support portion so as to be orthogonal to the inclined surface direction in the axial direction and screwed into the screw hole. Various inclined surfaces can be provided regardless of the direction, and the sound generating device can be firmly fixed only with screws.
As a result, the molded part can be die-cut and the screw can be advanced from the back surface of the support portion so as to be orthogonal to the inclined surface direction in the axial direction and screwed into the screw hole. Various inclined surfaces can be provided regardless of the direction, and the sound generating device can be firmly fixed only with screws.

  In order to achieve the above object, in addition to the configuration of the invention of claim 2, in the invention of claim 3, the inner peripheral wall surface of the through hole in the case where the inclined surface faces downward is the lower side, and the inclined surface is the same. The gist is that the inner peripheral wall surface of the through-hole in the upward direction is such that the upper side is substantially orthogonal to the inclined surface.

In such a configuration, in addition to the operation and effect of claim 2, when inserting the screw into the through hole, the screw can be advanced into the through hole along the inner peripheral wall surface substantially orthogonal to the inclined surface. It is possible to increase the contact area between the head of the screw and the peripheral edge of the through hole on the back side of the hole.
In order to achieve the above object, in the invention of claim 4, in addition to the structure of any one of claims 1 to 3, the screw hole is directly formed in a main body frame constituting a part of the sound generator. The gist of this is
In such a configuration, in addition to the operation and effect of any one of the first to third aspects of the invention, the frame for fixing the sound generating device can be fixed to the inclined surface as it is without preparing a separate frame. Contributes to reduction, weight reduction, simplification of installation work of sound generators, etc.

  In the invention described in each of the above claims, the molded part having the support portion on which the inclined surface for mounting the sound generating device is inclined can be removed, and the sound generating device is inclined. It becomes possible to fix firmly to the surface only with screws.

Hereinafter, a first embodiment in which the present invention is applied to a pachinko machine will be described with reference to the drawings. First, the outline of the pachinko machine will be described based on FIG. 1 and FIG.
A gaming machine main body 13 and a front frame 14 are attached to an outer frame 12 of the pachinko machine 11 via a hinge 15 so as to be opened and closed. The gaming machine main body 13 is a panel-like structural member that forms the structural core of a pachinko gaming machine, and a mechanism panel 18 composed of a tank, a prize ball discharge unit 16, a mounting base 17 and the like (not shown) is provided on the back surface thereof. It is arranged. A gaming board 20 is mounted on the upper body of the gaming machine body 4 (the gaming board 20 is omitted in FIG. 2). The front surface of the game board 5 is a game surface 21 configured substantially vertically. In FIG. 1, the illustration of nails implanted in the game surface 21 is omitted. A glass window G is fitted at a position above the front frame 14, and an upper tray 22 is formed at a position below the glass window G. A cover plate 23 as a front panel is disposed below the front frame 14. The cover plate 23 is attached to the gaming machine body 13 through a hinge 15 so as to be opened and closed. The cover plate 23 is formed with a lower tray 24 that protrudes forward. An operation handle 27 is attached to the right side of the lower tray 24. On the front surface of the front frame 14, a decorative panel 25 incorporating a light source such as an LED (not shown) as a decorative member, an uneven portion 26 as a decorative member, and the like are formed.
Near the center of the back surface of the cover plate 23, a speaker device 30 as a sound generator is disposed.

Next, the mounting structure in the vicinity of the cover plate 23 where the speaker device 30 is mounted will be described in more detail.
The speaker device 30 is attached to a support portion 31 of a base plate 29 that constitutes a part of the cover plate 23. The base plate 29 is a horizontally long rectangular plate having a uniform thickness, and is formed integrally by plastic molding using a mold (not shown). The die cutting direction of the base plate 29 is the front-rear direction perpendicular to the reference plane V1 extending vertically in FIG. 3, that is, the direction of two arrows in FIG. 3 (that is, formed by two divided molds). To do). Here, the reference plane V1 of the base plate 29 refers to a plane extending in a substantially vertical direction in the installed state of the pachinko machine 11 (almost, the fact that the pachinko machine 11 is actually installed slightly tilted backward. To be). A front plate 32 is disposed on the front surface of the base plate 29. A skeleton of the cover plate 23 is constructed by the base plate 29 and the front plate 32. A number of sound generating holes 33 serving as outlets for sound effects output from the speaker device 30 are formed at positions facing the inner side of the lower tray 24 of the front plate 32.

As shown in FIGS. 3 to 5, the support portion 31 formed by integral molding at a position closer to the center of the base plate 29 is composed of a pair of rearward protruding portions 34 a and 34 b arranged on the left and right sides at a predetermined interval. . This interval is set according to the width of the speaker device 30 so as not to block the sound output from the speaker device 30. Both rear protrusions 34a and 34b are symmetrical, and are composed of a rear projecting portion 35 that is formed wider toward the upper side and an inclined portion 36 that is bent from the rear projecting portion 35 in a direction opposite to the hand of the heel. Has been. The inclined portion 36 is a plate body that is inclined backward toward the upper side, and ends of the inclined portions 36 that face each other are curved in accordance with the shape of the speaker device 30. The rear surface of the inclined portion 36 is an inclined surface 37 with which the front surface of the speaker device 30 abuts. In the first embodiment, the inclined surface 37 is inclined backward with respect to the reference surface V1 of the base plate 29 at an angle θ.
A through hole 38 penetrating in the thickness direction of the inclined portion 36 is formed at a position closer to the top and bottom of the inclined portion 36 of each of the rear protrusions 34a and 34b. The through hole 38 is formed in a circular shape in cross section, and its inner peripheral wall 38a extends along a direction orthogonal to the reference plane V1 of the base plate 29, that is, in a die cutting direction V2.

As shown in FIGS. 3 to 7, the speaker device 30 is fixed to the support portion 31 (rear protruding portions 34 a and 34 b) by screwing with a tapping screw 41 via the mounting frame 40.
The speaker device 30 includes a metal main body frame 42 that is widened toward the front, a vibration mechanism 43 that includes a coil, a magnet, and the like that are fixed to the bottom of the main body frame 42, and a cone as a vibration plate. A known speaker structure composed of a cone-shaped paper 44 is used. The cone paper 44 is stretched between the front opening of the main body frame 42 and the vibration mechanism 43.
The mounting frame 40 used for mounting the speaker device 30 is a mounting member having a bowl-shaped outer shape corresponding to the outer shape of the main body frame 42 of the speaker device 30, and is formed by plastic molding using a mold (not shown). It is formed integrally. The mounting frame 40 includes a surrounding portion 45 that surrounds the main body frame 42 and a flange-like contact edge 46 that is integrally formed on the periphery of the circular opening at the tip of the surrounding portion 45. As shown in FIGS. 4 and 5, the flange-like contact edge 46 has a square outer shape, and a screw hole 47 is formed in each of the four corners. The screw hole 47 is configured as a through hole penetrating in the thickness direction of the thick portion 48 configured to be thicker than the plate thickness of the flange-shaped contact edge 44, and the central axis P thereof is connected to the front surface 46 a of the flange-shaped contact edge 46. It is orthogonal to the inclined surface 37 in a state of being arranged on the support portion 31 (see FIG. 6).
The tapping screw 41 includes a screw body 49 and a head 50 each having a male screw formed on the outer periphery. The tip of the screw body 49 is sharp. The head 50 is formed with a plus groove 51 serving as an engaging portion when the tapping screw 41 is rotated by an instrument such as a screwdriver.

The attachment structure of the speaker device 30 will be described in more detail together with the attachment process. The speaker device 30 is attached as follows, for example.
First, the speaker device 30 is accommodated in the mounting frame 40, and the front surface 46 a of the flange-like contact edge 46 on the front surface of the main body frame 42 is brought into close contact with the inclined surface 37. At this time, since the front end 46a of the main body frame 42 of the speaker device 30 and the front surface 46a of the flange-like contact edge 46 of the mounting frame 40 are flush with each other, the front end of the main body frame 42 is also brought into contact with the inclined surface 37.
The position of the mounting frame 40 is adjusted by moving it up, down, left, and right, so that the screw hole 47 is aligned with the through hole 38 on the inclined portion 36 side. And, the back side of the inclined portion 36 (corresponding to the front side as the whole pachinko machine 11. Accordingly, the “front side” is the attachment side of the speaker device 30 of the base plate 29, and the rear side as the whole pachinko machine 11. The same applies hereinafter), and the tapping screw 41 is inserted into the through-hole 38 so that the center line axis Q is orthogonal to the inclined surface.
As shown in FIG. 6, the diameter d of the screw main body 49 is defined by a line segment T <b> 1 passing through the upper corner of the inner opening of the through hole 38 of the inclined portion 36 and perpendicular to the inclined surface 37 and the lower corner of the outer opening of the through hole 38. It is configured to be smaller than the interval S between the street inclined surface 37 and the line segment T <b> 2 perpendicular to the street inclined surface 37. This is because the screw main body 49 cannot interfere with the inner peripheral wall 38a and the tapping screw 41 cannot be advanced so as to be orthogonal to the inclined surface 37 without such a configuration. Further, the diameter d of the screw body 49 is configured to be slightly larger than the inner diameter of the screw hole 47 of the mounting frame 40. This is because the tapping screw 41 is screwed into the screw hole 47 at the same time as it is biting into the screw hole 47 by the tapping screw 41 (that is, while threading).

  The tapping screw 41 is inserted into the through hole 38 and the tip is pressed against the screw hole 47. At this time, the center axis Q of the tapping screw 41 is made to coincide with the center axis P of the screw hole 47. The tapping screw 41 is rotated while being pressed, and the screw main body 49 is gradually advanced while biting into the inner peripheral surface 47 a of the screw hole 47. As shown in FIG. 7, the mounting frame 40 is attached to the support portion 31 (rear protruding portions 34a and 34b) by bringing the head 50 of the tapping screw 41 into contact with the periphery of the through hole 38 on the back side of the inclined portion 36 and tightening it further. Detained (state of FIG. 7). In the first embodiment, the attachment is completed by screwing the tapping screw 41 into the screw hole 47 by the same operation in four places. As a result, the speaker device 30 covered with the mounting frame 40 is pressed against the inclined surface 37 of the support portion 31.

By adopting such a configuration, the following effects are achieved in the first embodiment.
(1) Since the inner peripheral wall 38a of the through hole 38 formed in the inclined portion 36 extends along the die cutting direction V2, it is possible to perform die cutting when the base plate 29 is molded by plastic molding. . Then, the tapping screw 41 can be inserted so as to be orthogonal to the inclined surface 37 using the through hole 38. As a result, the center line axis Q of the tapping screw 41 can be made to coincide with the center axis P of the screw hole 47, and the attachment frame 40 can be screwed to be brought into close contact with the inclined surface 47. Since the speaker device 30 is disposed on the inclined surface 37, the sound is directed toward the face of the player diagonally forward and upward, so that the sound quality of the sound effect is improved and the sound is more easily heard and realistic. It will be a thing.
Further, even if the inclination of the inclined portion 36 is increased, the inner peripheral wall 38a of the through-hole 38 can be removed if it is extended along the release direction, so that various inclination angles and inclination directions can be obtained. It is possible to correspond to the sloped portion.
(2) Since the tapping screw 41 is securely screwed into the screw hole 47, the speaker device 30 is firmly brought into close contact with the inclined surface 37 of the support portion 31 via the mounting frame 40, so that the sound may be distorted by its own vibration. Absent.
(3) When the through-hole 38 is formed in the plate-like inclined portion 36, the depth of the through-hole 38 is shallow, and the centerline axis Q direction of the tapping screw 41 is inserted perpendicularly to the inclined surface 37. The screw main body 49 does not interfere with the inner peripheral surface 38a of the through hole 38 (that is, the interval S is not narrowed), and the screw can be inserted without opening the through hole 38 greatly. The portion 50 can be firmly engaged with the periphery of the through hole 38.

(Embodiment 2)
Next, the second embodiment will be described with reference to FIGS. The second embodiment is a variation that is relatively close to the first embodiment, except that only the shape of the through-hole 38 is different and the other configurations are the same. Therefore, the configuration different from that of the first embodiment will be mainly described, and the same components will be denoted by the same reference numerals in the drawing, and detailed description thereof will be omitted.
In the second embodiment, the inner peripheral wall 38a of the through hole 38 formed in the inclined portion 36 is not an inner peripheral wall 38a having a uniform vertical width on the front and back sides, but is configured such that the front surface side is wider than the back surface side. That is, as shown in FIG. 10 (a), a circular opening is formed on the back surface side, and as shown in FIG. 10 (b), an elliptical shape having a long axis in the vertical direction is formed on the front surface side. The lower side wall 55a of the inner peripheral wall 38a extends in a direction orthogonal to the inclined surface 37, and the upper side wall 55b extends in a direction orthogonal to the reference plane V1 of the base plate 29.
With such a configuration, the same effects as in (1) to (3) of the first embodiment are obtained, and the tapping screw 41 is extended in a direction orthogonal to the inclined surface 37 using the lower wall portion 55a as a guide. Can be issued. Further, as can be seen in comparison with the first embodiment, since the opening portion of the through hole 38 on the back surface side of the inclined portion 36 becomes smaller, the contact area between the head 50 of the tapping screw 41 and the periphery of the through hole 38 is increased. The tapping screw 41 can be firmly tightened.

(Embodiment 3)
Next, the third embodiment will be described with reference to FIGS. The third embodiment is a variation that is relatively close to that of the first embodiment. Only the mounting structure of the speaker device 30 is different, and the other configurations are the same. Therefore, the configuration different from that of the first embodiment will be mainly described, and the same components will be denoted by the same reference numerals in the drawing, and detailed description thereof will be omitted.
In the third embodiment, the speaker device 30 is directly fixed to the support portion 31 without using an intermediate member such as the attachment frame 40.
A flanged contact edge 61 is integrally formed at the front end of the main body frame 42 of the speaker device 30. The flange-like contact edge 61 has a square outer shape, and a burring-processed screw hole 62 is formed in each of the four corners. With burring, after forming a pilot hole, press the center of the pilot hole and process the concave conical part 63 on the back side of the flange-shaped contact edge 61 while expanding the pilot hole (deck pressing dimple process) It is a construction method.
With such a configuration, the same effects as those of the first embodiment (1) to (3) can be obtained, and the speaker device 30 can be directly connected to the inclined surface 37 without using an intermediate member such as the attachment frame 40. Therefore, this contributes to cost reduction, weight reduction, simplification of the operation of mounting the sound generator, and the like.

The present invention can be implemented with the following modifications.
-The shape of the said support part 31 is an example, Comprising: It is not limited.
-As long as it is a directional speaker apparatus, it will not be limited to the above.
In each of the above embodiments, the speaker device 30 is disposed on the back surface of the cover plate 23, but it is not limited to this position. For example, it may be arranged on the front frame 14. Of course, a plurality of speaker devices may be provided.
As the screw, the tapping screw 41 is used in each of the above embodiments, but it is also possible to fasten using other screws such as bolts and nuts.
In the above embodiment, the speaker device 30 is disposed on the back surface of the cover plate 23. However, the speaker device 30 may be disposed on the front plate 32 in the case of the front surface, for example, the cover plate 23.
In the second embodiment, the through hole 38 is expanded toward the front surface, but may be expanded toward the back surface. In the second embodiment, the lower side wall 55a extends in the direction orthogonal to the inclined surface 37, and the upper side wall 55b extends in the direction orthogonal to the reference plane V1 of the base plate 29. In other words, the inner wall 38a of the through hole 38 has been expanded on the side of the upper side wall 55b.
Further, the expanding direction may be performed in both directions instead of either the front or the back. That is, you may make it comprise a drum shape by the side cross-sectional shape of a through-hole.
-Although the said embodiment demonstrated the example applied to the pachinko machine, from the meaning of this invention, it is free to apply to other game machines, for example, a slot machine, a pacilot, etc. In addition, it is free to implement in a mode that does not depart from the spirit of the present invention.
