  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In this embodiment, a pachinko machine that is a kind of a ball game machine, in particular, a first type pachinko game machine will be described as an example of the game machine. Note that it is naturally possible to use the present invention for the third kind pachinko gaming machine and other gaming machines.

  FIG. 1 is a front view of a pachinko machine P according to an embodiment of the present invention. As shown in FIG. 1, the pachinko machine P includes a wooden outer frame 1 formed in a substantially rectangular shape when viewed from the front, and an inner frame 2 formed in substantially the same outer shape as the outer frame. The inner frame 2 is pivotally supported by the outer frame 1 at two upper and lower ends of the left edge (left side in FIG. 1), and is configured to be swingable with respect to the outer frame 1.

  A front frame 3 is disposed on the front side of the inner frame 2 (the front side in FIG. 1) so as to cover the inner frame 2. As shown in FIG. 1, the front frame 3 is formed in a substantially rectangular shape when viewed from the front, and the inner frame 2 is formed by opening and closing shafts 4 disposed at two upper and lower positions on the left edge (left side in FIG. 1). Is pivotally supported. Therefore, the front frame 3 is configured to be openable and closable with respect to the inner frame 2 (see FIG. 2).

  A substantially circular opening 3a is formed in a substantially central portion of the front frame 3, and this opening 3a is a transparent glass plate attached to the back side of the front frame 3 (the back side in FIG. 1). 5 is covered. On the back side of this glass plate 2 (the back side in FIG. 1), a game board 6 is disposed facing each other with a predetermined interval L (see FIG. 5). A game area into which a ball is driven is formed between the opposing surfaces. The player can enjoy the game by visually recognizing the sphere flowing down the game area through the glass plate 5 of the opening 3a. Note that the game board 6 is attached to the back side (the back side in FIG. 1) of the inner frame 2 described above.

  Around the game area (game board 6), there are provided a plurality of winning holes (not shown) through which 5 to 15 balls are paid out when the balls are won. In addition, a liquid crystal display (hereinafter simply referred to as “LCD”) 8 for displaying a plurality of types of identification information and the like is provided in the approximate center of the game board 6.

  Below the LCD 8, a symbol operating port (first type starting port) 9 is provided, and when the ball wins the symbol operating port 9, the above-described variation display of the LCD 8 is started. Below the symbol operating port 9, a specific winning port (large winning port) 10 is provided. The specific winning a prize opening 10 is a big hit when the display result after the fluctuation of the LCD 8 matches one of the predetermined symbol combinations, and a predetermined time (for example, 30 seconds elapses) so that the ball can easily win a prize. (Or until 10 balls have been won).

  A V zone 10a is provided in the specific winning opening 10, and when the ball passes through the V zone 10a while the specific winning opening 10 is opened, a continuation right is established and the specific winning opening 10 is closed. Thereafter, the specific winning opening 10 is opened again for a predetermined time (or until a predetermined number of balls win the specific winning opening 10).

  The front frame 3 is made of a resin material, and an upper plate 7 is integrally formed by injection molding on the front surface (front side of FIG. 1). This upper plate 3 is a member for storing a sphere, and is formed so as to protrude toward the front (the front side in FIG. 1). Therefore, when the player grabs the upper plate 7 and intentionally or carelessly draws it to the near side, the front frame 3 is bent in the drawing direction, and the distance between the opposing surfaces of the glass plate 5 and the game plate 6 is increased. Will be widened.

  Here, in general, the interval between the two nails 11 disposed immediately above (upstream) the symbol operating port 9 gradually increases in a C shape from the root toward the tip (glass plate 5). Since it is erected in the mode, as described above, when the gap between the opposing surfaces of the glass plate 5 and the game board 6 is widened, the balls that have been driven into the game area are more likely to win the symbol operating port 9. Therefore, in order to prevent this widening, an engagement fitting 31 (see FIG. 5) is disposed on the back side of the front frame 3 (the back side in FIG. 1). By engaging the engagement metal fitting 31 with the engagement metal fitting 32 (see FIG. 3) of the inner frame 2, the deflection of the front frame 3 is suppressed, and the gap between the opposing surfaces of the glass plate 5 and the game board 6 is reduced. Widening is suppressed. The details of the engagement fitting 31 and the engagement fitting 32 will be described later.

  Below the front frame 3 (lower side in FIG. 1), a front lower door 12 is disposed so as to be openable and closable. In the substantially central portion of the front lower door 12, a lower plate 13 for storing the balls that could not be stored in the above-described upper plate 7 is formed in a substantially box shape with the upper surface (upper side in FIG. 1) released. On the right side (the right side in FIG. 1) of the lower plate 13, an operation handle 14 that is operated by the player to drive the ball into the game area is disposed.

  FIG. 2 is a perspective view of the pachinko machine P and shows a state in which the front frame 3 is released. As described above, the inner frame 2 is pivotally supported on the front surface side of the outer frame 1, and the game board 6 is attached to the rear surface side of the inner frame. Further, the front frame 3 is pivotally supported by the inner frame 2 via opening / closing shafts 4 disposed at two upper and lower positions, and is released from the inner frame 2 as shown in FIG.

  On the back side of the front frame 3, as shown in FIG. 2, a support member 15 formed in a rectangular frame shape in front view is disposed so as to surround the periphery of the opening 3a. The support member 15 is a member mainly for reinforcing the front frame 3 and is made of a metal material such as stainless steel. The support member 15 is screwed and fixed to the back side of the front frame 3 with a plurality of screws (not shown). As a result, the rigidity of the front frame 3 as a whole is improved, and even if the upper plate 7 or the like is gripped and pulled by the player as described above, the front frame 3 is prevented from being bent.

  Moreover, the glass plate 5 mentioned above is engage | inserted by the inner peripheral side of the supporting member 15 (refer FIG. 3). Thus, since the glass plate 5 is disposed on the front frame 3 via the support member 15 having high rigidity, the upper plate 7 and the like are attracted by the player, and the front frame 3 itself is bent. However, since it can suppress that the glass plate 5 displaces in conjunction with the deformation | transformation, it can suppress that the opposing surface space | interval of the glass plate 5 and the game board 6 is expanded.

  Three engagement fittings 31 are attached to a portion of the support member 15 on the back side (front side in FIG. 2) and on the opening / closing shaft 4 side (right side in FIG. 2). On the side, three engaged metal fittings 32 are attached at positions that can engage with the engaging metal fittings 31 when the front frame 3 is closed. Here, with reference to FIG. 3, the detail of the engagement metal fitting 31 and the to-be-engaged metal fitting 32 is demonstrated.

  FIG. 3 is an enlarged perspective view showing a part III in FIG. As described above, the flat support member 15 is screwed and fixed to the back side of the front frame 3. As shown in FIG. 3, the support member 15 is formed to be bent in a substantially L shape in cross section, and one end side thereof is formed in a substantially U shape in cross section. A glass plate 5 is fitted into the formed portion.

  An engagement fitting 31 is attached to the back side of the support member 15. The engagement fitting 31 is a member for engaging an engagement fitting 32 described later, and is made of a metal material such as stainless steel. As shown in FIG. 3, the lower end side (lower side in FIG. 3) of the flat plate body that is screwed and fixed to the support member 15 with the screw 33 is bent substantially vertically. It is formed to be curved toward the inner frame 2. An engagement surface 31a is formed on the inner peripheral surface side of the curved portion, and the engagement surface 31a is brought into contact with an engaged surface 32a of an engaged metal fitting 32, which will be described later. The tool 31 and the metal fitting 32 are engaged.

  Since the screw 33 is screwed to the support member 15 and also to the front frame 3, the screw 33 is screwed to the support member 15 and the support member 15 is fixed to the front frame. It also has the function of screwing and fixing to 3. As a result, the number of screws can be reduced, and the component cost can be reduced.

  As shown in FIG. 3, the front side of the inner frame 2 is recessed at a position facing the curved portion (lower side in FIG. 3) of the engagement fitting 31 described above, and this recessed portion is defined as a recess 2a. ing. The recess 2a is a space for avoiding interference with the rotation locus of the engagement fitting 31 when the front frame 3 is opened and closed (see FIG. 5). In the space of the recess 2a, a substantially flat metal fitting 32 is attached, and the engagement surface 32a engaged with the engagement surface 31a of the engagement metal 31 described above is a metal to be engaged. It is formed on the back side of the tool 32 (the right back side in FIG. 3).

  4 is a cross-sectional view taken along line IV-IV in FIG. The engaged metal fitting 32 is formed in a flat plate shape from a metal material such as stainless steel, and is screwed and fixed with a screw 34 into the internal space of the concave portion 2a provided in the inner frame 2 as shown in FIG. ing. Since the engaged metal fitting 32 is disposed in a state in which one side (right side in FIG. 4) protrudes, the engaged surface 32a formed on the back surface side (upper side in FIG. 4) of the protruding portion is engaged. It can be engaged with the engagement surface 31 a of the metal fitting 31.

  Thus, since the metal fitting 31 to be engaged with the metal fitting 31 is made of a metal material, the metal fitting can be engaged more firmly. Moreover, since the engaging part with the engaging metal fitting 31 is formed by attaching another member (engaged metal fitting 32) to the inner frame 2, this engaging part is integrated with the inner frame 2 by injection molding. Since it is not necessary to mold the inner frame 2 into a complicated shape as compared with the case of molding, the molding cost can be reduced correspondingly, and the degree of freedom in design is increased. Can be formed into a higher strength shape.

  A screw 34 for screwing and fixing the engaged metal fitting 32 to the inner frame 2 is screwed to the inner frame 2 and also to the game board 6 disposed on the back side of the inner frame 2 as shown in FIG. Since the game board 6 is screwed together, the game board 6 is connected to the engaged metal fitting 32 through the screw 34. Therefore, in a state where the engagement fitting 31 is engaged with the engagement fitting 32, the glass plate 5 and the game board 6 are connected via the engagement fitting 31 (support member 15) and the engagement fitting 32 (screw 34). It will be connected (refer to Drawing 5).

  As a result, for example, when the player holds the upper plate 7 or the like and the glass plate 5 is drawn together with the front frame 3, the game board 6 is connected to the engagement fitting 31 (support member 15) and the engaged metal. Since it is pulled in the same direction as the glass plate 5 via the tool 32 (screw 34), both members of the game board 6 and the glass plate 5 are kept relative to each other while keeping the facing surface distance L (see FIG. 5) constant. In other words, it is displaced in the same direction, and the widening of the distance between the opposing surfaces can be suppressed.

  Here, the engaged surface 32a of the engaged metal fitting 32 is formed in an outwardly convex arc shape, and the center of curvature of the arc portion of the engaged surface 32a is as shown in FIG. Furthermore, it coincides with the axis center of the opening / closing shaft 4 that pivotally supports the front frame 3 so as to be opened and closed. The curvature radius is R2. On the other hand, the engagement surface 31a of the engagement fitting 31 is formed to be curved in an inwardly convex arc shape, and this engagement surface 31a arc portion is a curvature radius of the arc surface portion of the engaged surface 32a described above. The radius of curvature R1 is substantially the same as R2. However, the center of curvature of the arcuate portion of the engaging surface 31a is slightly offset in the direction of the front side (left side in FIG. 4) of the front frame 3 with respect to the center of curvature of the engaged surface 32a (that is, the axis center of the opening / closing shaft 4). Has been.

  Therefore, when the engagement surface 31a of the engagement fitting 31 engages the engagement surface 32a of the engagement fitting 32 (see FIG. 5), the engagement surface 32a is lowered by the engagement surface 31a (lower side in FIG. 4). ) And the engaged metal fitting 32 is elastically deformed, so that both members can be firmly engaged without rattling, and as a result, the distance between the opposing surfaces of the glass plate 5 and the game board 6 can be increased. Widening can be suppressed more reliably. Further, for example, the front frame 3 rattles against the inner frame 2 due to assembly dimensional tolerance in manufacturing or wear of the opening / closing shaft 4 due to use, and as a result, the glass plate 5 and the game board 6 face each other. Even when the backlash occurs, the backlash between the glass plate 5 and the game board 6 can be absorbed by the elastic deformation at the time of engagement of the metal fitting 32 to be engaged. The surface interval can be kept constant.

  In this way, by forming the engaging surface 31a and the engaged surface 32a in an arc shape in this way, the engaging surface 31a and the engaged surface 32a that are in contact with each other on the rotation locus centering on the opening / closing shaft 4 are provided. Since the contact area can be maximized, the engagement fitting 31 and the engagement fitting 32 can be firmly engaged.

  The engagement fitting 31 includes a guide surface 31b formed on the distal end side (upper side in FIG. 4) of the engagement surface 31a. The guide surface 31b is a part for guiding the engaging surface 31a to the engaged surface 32a of the engaged metal fitting 32, and is formed in a tapered shape as shown in FIG. Thereby, as described above, the engaging surface 31a offset with respect to the engaged surface 32a can be properly guided to a predetermined position and reliably engaged with the engaged surface 32a.

  Next, with reference to FIG.4 and FIG.5, the effect | action of the engaging metal fitting 31 and the to-be-engaged metal fitting 32 comprised as mentioned above is demonstrated. FIG. 5 is a sectional view taken along line IV-IV in FIG. 3 and shows a state in which the front frame 3 is closed.

  When the swinging operation is performed in the direction in which the front frame 3 is closed from the state shown in FIG. 4, the engagement fitting 31 moves on the rotation locus around the opening / closing axis 4 in conjunction with the swinging operation of the front frame 3. The guide surface 31b is first brought into contact with the engaged metal fitting 32, and then the engagement surface 31a guided by the guide surface 31b is placed on the engaged surface 32a of the engaged metal fitting 32. And presses the engaged surface 32a. When the swinging operation of the front frame 3 is completed and the front frame 3 is completely closed, as shown in FIG. 5, the glass plate 5 attached to the front frame 3 via the support member 15 is played. 6, the engagement surface 31a of the engagement fitting 31 and the engagement surface 32a of the engagement fitting 32 are engaged with each other.

  On the other hand, when the front frame 3 is swung in the release direction from the state shown in FIG. 5, the engagement fitting 31 moves on the rotation trajectory around the opening / closing shaft 4 in conjunction with the swing operation of the front frame 3. Is rotated in the direction opposite to the arrow A, and the engaging surface 31 a slides on the engaged surface 32 a of the engaged metal fitting 32. When the front frame 3 is further swung in the releasing direction, the engaging surface 31a is separated from the engaged surface 32a as shown in FIG. The combined state is released.

  Thus, the engagement between the engagement fitting 31 and the engagement fitting 32 and the release thereof are automatically performed in conjunction with the opening / closing operation of the front frame 3. That is, both members (the engaging metal fitting 31 and the engaged metal fitting 32) are automatically engaged only by opening and closing the front frame 3, and the engagement state of both members is automatically released. Therefore, there is no need to perform a special operation for engaging both members, a special operation for releasing the engagement state of both members, etc., simplifying the work and improving work efficiency accordingly. be able to. Furthermore, since both members are automatically engaged, it is possible to prevent the manager from forgetting to perform the engaging operation, and the engagement state of both members is not released unless the front frame 3 is released. Therefore, the illegal act of illegally releasing the engaged state is suppressed.

  Thus, according to the pachinko machine P in the present embodiment, the engaging metal fitting 31 attached to the front frame 3 side and the engaged metal fitting 32 attached to the inner frame 2 side can be engaged. Therefore, it is possible to suppress the widening of the gap L between the opposing surfaces of the game board 6 and the glass plate 5 by engaging these two members. As a result, even when the upper plate 7 or the like is pulled toward the front by the player, the path width through which the ball can pass in the game area can be kept constant, and as a result, a pachinko machine that can perform a fair game Machine P can be obtained.

  FIG. 6 is an external perspective view of the pachinko machine P viewed from the back side. The outer frame 1 includes four wooden flat plates whose both ends are convexly or concavely formed, and the convex portions (concave portions) of the respective wooden flat plates are adjacent to the concave portions ( By fitting to the convex portion, as shown in FIG. 6, it is assembled in a substantially rectangular frame shape in front view.

  Both ends of adjacent wooden flat plates are screwed together by wood screws 63 as shown in FIG. Therefore, compared with the case where a wooden plate is combined using a nail like the conventional game machine, a wooden plate can be combined more firmly. In particular, since the male screw 63 is bitten into a wooden flat plate, the wood screw 63 exhibits a better binding force with respect to the load in the direction in which the wood screw 63 (nail) is pulled out than when a nail is used. To do.

  Further, as shown in FIG. 6, a metal reinforcing plate 61 formed by bending in an L shape in cross section is attached to the concave and convex fitting portion of the wooden flat plate. In a conventional gaming machine, the metal reinforcing plate 61 is riveted to a wooden flat plate. For this reason, there has been a problem that the wooden flat plate is broken by the pressure contact force in the caulking operation of the rivet end. Therefore, in this embodiment, the metal reinforcing plate 61 is screwed and fixed to the wooden flat plate using the wood screw 63. Thereby, the metal reinforcement board 61 is fixed firmly, without damaging a wooden flat plate. Similarly, the metal reinforcing plate 62 is also screwed and fixed to the side surface portion of the wooden flat plate using the wood screw 63.

  In addition, a ball launcher 50 to be described later is disposed in the lower left part of the back side of the pachinko machine P. The ball launcher 50 is a device for launching a ball to the game area, and is driven in conjunction with the operation of the operation handle 14 described above.

  FIG. 7 is an exploded perspective view of the ball launching device 50 as seen from the back side, and an arrow A in the drawing shows the rotation direction of the handle ring 24 when the hitting force of the hitting ball 44 is increased. . As shown in FIG. 7, the ball launcher 50 includes a handle 14 that is operated by a player. As described above, the handle 14 is disposed on the front lower door 11 on the front side of the pachinko machine P (see FIG. 1), and the handle main body 22 fixed to the front lower door 11 and the handle main body 22 are The shaft 23 is provided so as to be relatively rotatable, the handle ring 24 is operated to rotate the shaft 23, and the cap 25 is fixed to the handle body 22.

  The handle body 22 and the cap 25 are formed of a synthetic resin material such as ABS resin, while the shaft 23 is formed of a conductive metal material. The handle ring 24 is provided between the handle main body 22 and the cap 25, and is formed of a synthetic resin material, and the surface thereof is plated with a conductive metal material or the like.

  The shaft 23 of the handle 14 is formed so as to be able to be inserted into a substantially flat support plate 40 in the ball emitting device 50, and a pulley 41 is connected thereto. The pulley 41 is for transmitting the rotation of the shaft 23 to a hitting ball 44 to be described later, and one end of a wire 42 formed of a wire is connected to the outer periphery thereof. This wire 42 is for transmitting the rotation of the shaft 23 of the handle 14 together with the pulley 41, and the other end is connected to the lower end of the swinging member 43a to which one end of the adjustment spring member 43 is connected. The swing member 43a is for transmitting the rotation of the shaft 23 transmitted by the wire 42 to the adjustment spring member 43, and is pivotally supported by the support plate 40 so as to be swingable (tilted). The wire 42 is suspended between the lower end of the swing member 43a and the lower end of the pulley 41.

  One end of the adjustment spring member 43 is connected to the upper portion of the swing member 43a. The adjusting spring member 43 is for applying a biasing force to the hitting ball rod 44, which will be described later. The adjusting spring member 43 is formed by a tension spring formed of a coil spring, and the other end is above the support shaft 44a of the hitting ball rod 44. It is connected to the part. The hitting ball 44 is for hitting a ball at its upper end and driving it into the game area, and is pivotally supported on the support plate 40 via a support shaft 44a. The hitting ball 44 is biased toward the right side of FIG. 7 by the adjusting spring member 43 described above, and the biasing direction by the adjusting spring member 43 is configured to substantially coincide with the hitting direction of the ball. ing.

  A weight portion 44 c is disposed at the lower end of the hitting ball 44. The weight portion 44c is a portion for increasing the weight of the lower end portion of the hitting ball 44, and is formed to protrude toward the opposite side of a stopper member 44 described later. As a result, since the center of gravity of the hitting ball 44 is separated from the support shaft 44a by the weight of the weight portion 44c, the rotational inertia force when swinging about the support shaft 44a is improved accordingly. As a result, the ball can be hit and fired more firmly. Therefore, by providing the weight portion 44c, other portions can be made thinner, and the weight of the hitting ball 44 as a whole can be reduced accordingly.

  The weight portion 44c may be provided integrally with the ball striking ball 44, or the weight portion 44c may be formed as a separate body from a heavier material, and this may be hit by welding, bonding, screwing, or the like. You may comprise so that it may attach to the bulb 44. In this case, you may comprise so that the attachment position of the weight part 44c can be adjusted. Moreover, although the weight part 44c was arrange | positioned below the spindle 44a, you may arrange | position above the spindle 44a, Furthermore, you may arrange | position two or more above and below. .

  A stopper member 40a with which the lower end of the hitting ball rod 44 abuts is disposed below the hitting ball rod 44 and below the support plate 40, and the support shaft of the hitting ball rod 44 is supported by the stopper member 40a. Oscillation is restricted in the clockwise direction in FIG. 7 around 44a. In the vicinity of the support shaft 44a of the hitting ball 44 and on the side opposite to the connecting side of the adjusting spring member 43 (left side in FIG. 7), an extending portion 44b extends outward, and this extending portion A firing motor 45 is disposed in the vicinity of 44b. The firing motor 45 is used to apply power for hitting the ball to the hitting ball 44, and its rotation shaft (not shown) is used to play the extension 44b of the hitting ball 44. A cam 46 is fixed. The firing motor 45 is configured such that its rotation shaft is rotatable at approximately 100 rpm (100 rotations per minute), and the firing cam 46 is rotated based on the rotation of the rotation shaft.

  The firing cam 46 drives the firing motor 45, that is, pushes down the extended portion 44b of the hitting ball 44 in accordance with the rotation of the rotating shaft thereof, thereby causing the adjusting spring member 43 to move the adjusting ball member 44. It is for repelling in the counter-biasing direction (left side in FIG. 7) and causing the upper end of the hitting ball 44 to recoil in the biasing direction (right side in FIG. 7) by the adjusting spring member 43. A substantially crescent-shaped protrusion 46a that protrudes outward is provided. The protruding portion 46a protrudes toward the extended portion 44b of the hitting ball rod 44 described above, and the extended portion 44b described above extends at a portion where the protruding portion 46a intersects the rotation path.

  According to the ball launching device 50 configured as described above, the firing cam 46 is rotated in the clockwise direction in FIG. 7 along with the rotation shaft of the firing motor 45, and with this rotation, the hitting ball 44. The extended portion 44 b is pushed downward by the projection 46 a of the firing cam 46. When the extending portion 44b is pressed by the protrusion 46a, the upper end portion of the hitting ball rod 44 is tilted in the counter-biasing direction (the left side direction in FIG. 7) against the biasing force of the adjustment spring member 43. . When the firing cam 46 is further rotated by the firing motor 45 and the projecting portion 46a is disengaged from the extending portion 44b, the hitting force (restoring force) of the adjustment spring member 43 causes the hitting ball 44 to recoil to return to the original state. The ball is hit and fired by the reaction of the hitting ball 44. In this case, since the rotational inertia force of the hitting ball 44 is improved by the weight portion 44c disposed at the lower end portion thereof, the ball can be hit and fired firmly correspondingly.

  Further, when the shaft 23 is rotated by rotating the handle ring 24 of the handle 14, the pulley 41 is rotated and the wire 42 is pulled toward the pulley 41 arrangement side (left side in FIG. 7). As the wire 42 is pulled, the swinging member 43a is tilted in the pulling direction of the wire 42. On the other hand, as the swinging member 43a is tilted, the adjusting spring member 43 is placed on the side where the hitting ball 44 is disposed. It is pulled and extended in the opposite direction. That is, by adjusting the amount of rotation of the handle ring 24, the tension amount (deformation amount) of the adjustment spring member 43 is changed and adjusted. As a result, the biasing force of the adjustment spring member 43 that biases the striking ball rod 44 is increased. It can be adjusted. By adjusting the urging force of the adjusting spring member 43, the striking force of the ball by the striking ball 44 is adjusted, the firing speed of the ball hit by the striking ball 44, and the ball that is launched toward the game area The amount of flight can be adjusted.

  The present invention has been described above based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications and changes can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, in the present embodiment, the case where the engaged metal fitting 32 is attached to the inner frame 2 has been described, but the engaged metal fitting 32 may be attached directly to the game board 6.

  In this embodiment, the engagement surface 31a of the engagement fitting 31 presses the engagement surface 32a of the engagement fitting 32 so that the engagement fitting 32 is engaged in an elastically deformed state. However, the present invention is not necessarily limited to this, and it may be configured to engage with a slight gap between the engaging surface 31a and the engaged surface 32a.

  In this embodiment, the center of curvature of the arc portion of the engagement surface 31a is offset with respect to the axis center of the opening / closing shaft 4 in order to engage the engaged metal fitting 32 in an elastically deformed state. However, conversely, the center of curvature of the arc portion of the engaged surface 32a may be offset from the axis center of the opening / closing shaft 4 (upward in FIG. 4), or the centers of curvature of both arc portions may be set. Both may be offset. In addition, the engagement surface shape of the engagement surface 31a and the engaged surface 32a does not necessarily need to be formed in a circular arc shape, and can of course be formed in, for example, a linear shape or a waveform.

  You may implement this invention in the pachinko machine etc. of a different type from the said Example. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Moreover, after the jackpot symbol is displayed, it may be implemented as a pachinko machine that enters a special game state under the condition that a ball is awarded in a predetermined area. Further, in addition to the pachinko machine, various game machines such as an alepacchi, a sparrow ball, a game machine in which a so-called pachinko machine and a slot machine are fused may be used.

  In the slot machine, for example, a symbol is changed by operating a control lever in a state where a symbol effective line is determined by inserting coins, and a symbol is stopped and confirmed by operating a stop button. Is. Accordingly, the basic concept of the slot machine is that “a variable display means for confirming and displaying a symbol after a symbol string composed of a plurality of symbols is displayed in a variable manner, and the symbol resulting from the operation of the starting operation means (for example, an operating lever). The change of the symbol is stopped due to the operation of the stop operation means (for example, the stop button) or after a predetermined time has elapsed, and the fixed symbol at the time of the stop is a specific symbol Is a slot machine provided with special game state generating means for generating a special game state advantageous to the player. In this case, the game medium is typically a coin, a medal or the like.

  In addition, as a specific example of a gaming machine in which a pachinko machine and a slot machine are integrated, a variable display means for displaying a symbol after a symbol string composed of a plurality of symbols is displayed, and a handle for launching a ball is provided. What is not provided. In this case, after throwing a predetermined amount of spheres based on a predetermined operation (button operation), for example, the change of the symbol is started due to the operation of the operation lever, for example, due to the operation of the stop button, or With the passage of time, the fluctuation of the symbol is stopped, and a jackpot state advantageous to the player is generated on the condition that the confirmed symbol at the time of stoppage is a so-called jackpot symbol. A lot of balls are paid out.

  A modification is shown below. 2. The gaming machine according to claim 1, wherein the front door includes a front frame on which an upper plate is integrally formed and the protection plate is attached, and the interval holding unit is attached to the front frame. The game board and the first engagement member include a first engagement member and a second engagement member attached to the main body, and by engaging the second engagement member with the first engagement member. A gaming machine 1 that is configured to suppress at least a widening of a distance between opposing surfaces of the protective plate.

  In the conventional gaming machine, the game area is relatively narrow, so there is a limit to the interest of the game. Therefore, by forming the upper dish integrally with the front frame, the game area can be formed wider and the interest of the game can be improved. By the way, in the conventional gaming machine, since the game area is narrow (the opening is small), the rigidity of the front frame is ensured, and the front frame is separated from the upper plate so that the player can grasp it. No part of the front frame was present. On the other hand, if the game area is wide (opening is widened), the rigidity of the front frame is reduced, and the upper plate is formed integrally, so that the player holds the upper plate. If you deliberately or carelessly pull it toward you, the front frame will bend toward you. As a result, since the protective plate attached to the front frame is also drawn toward the front, the distance between the opposing surfaces of the protective plate and the game board is widened, and the path width through which the ball can pass changes. You will not be able to play games.

  According to the gaming machine 1, the gaming machine 1 includes the interval holding means having the first engagement member attached to the front frame and the second engagement member attached to the main body, and the first engagement member By engaging the second engagement member, it is possible to prevent the facing surface interval between the game board and the protection plate from widening. Therefore, even when the upper plate is formed integrally with the front frame, the path width through which the ball can pass in the game area can be kept constant, and as a result, a gaming machine capable of playing a fair game can be obtained. it can.

  Here, in general, in a ball that has been driven into the game area, two nails arranged just above (upstream) the winning opening gradually spread in a C shape from the base toward the tip (protection plate). Since it is arranged in a manner, it becomes easier to win a prize opening or the like when the distance between the facing surfaces of the game board and the protection plate is widened. Therefore, an illegal act that makes it easy to win a prize opening or the like by pulling the upper plate forward by configuring the interval holding means so as to suppress at least the gap between the facing surfaces of the game board and the protection plate is widened. It can be effectively suppressed.

  Further, when the function of the interval holding means is limited to suppressing the widening of the opposed surface interval, the configuration of the interval holding means (first and second engaging means) is simplified, and the manufacturing cost and the part cost are reduced. Therefore, the product cost of the entire gaming machine can be reduced accordingly.

  In the gaming machine according to the gaming machine 1, the front door includes a support member made of a material that supports the front frame and is stronger than the front frame. The gaming machine 2 is characterized in that the member is attached to the supporting member. The high-strength material means that the rigidity strength is higher. For example, when the front frame is made of a resin material, the support member is made of a metal material (iron, aluminum, stainless steel, etc.). The case where it comprises is illustrated. Moreover, it is preferable from a surface of ensuring rigidity that a supporting member is formed in a front frame substantially frame shape from one or two or more members.

  According to the gaming machine 2, the front frame is supported by a support member made of a high-strength material that is more excellent in rigidity and strength. Therefore, since the rigidity of the entire front frame can be improved, it is possible to suppress the front frame that is gripped by the player and pulled toward the front from being bent forward. It is possible to suppress an increase in the distance between the facing surfaces of the protection plate attached to the frame and the game board.

  Furthermore, even if the upper plate or the like is drawn to the player and the front frame itself bends, the first engaging member of the spacing means is made of a material having a higher strength than the front frame and has higher rigidity. Since it is attached to the support member, it can be suppressed that the first engagement member is displaced in conjunction with the deformation of the front frame. As a result, the first engagement member is attached to the main body. Since the displacement of the second engaging member engaged with the game board is also suppressed, it is possible to prevent the opposing surface interval between the game board and the protection plate from being widened.

  In the gaming machine 2, the protection plate is attached to the support member. According to the gaming machine 3, even if the upper plate or the like is attracted by the player and the front frame itself is bent, the protective plate is made of a material having a higher strength than the front frame and becomes a support member having higher rigidity. Further, since the supporting member is engaged with the second engaging member attached to the main body via the first engaging member, the protective plate is interlocked with the deformation of the front frame. Can be suppressed, and as a result, it is possible to suppress the gap between the opposing surfaces of the protective plate and the game board from being widened.

  In any one of the gaming machines 1 to 3, the interval holding means is configured such that the engagement between the first engagement member and the second engagement member is performed in conjunction with the opening / closing operation of the front door. When the front door is closed, the first engagement member and the second engagement member are engaged, and when the front door is opened by a predetermined angle or more, the first engagement member and the second engagement member are engaged. The gaming machine 4 characterized in that the engagement with the member is released.

  According to the gaming machine 4, the engagement between the first engagement member and the second engagement member is performed in conjunction with the opening / closing operation of the front door. Therefore, just by closing the front door, both members can be engaged automatically, and there is no need to perform any special operation after closing the front door, simplifying the work and improving work efficiency. Can be made. Similarly, since the engagement state of both members can be automatically released simply by opening the front door, a special operation for releasing the engagement state of both members is omitted, and the work is accordingly performed. Efficiency can be improved.

  In any one of the gaming machines 1 to 4, the interval holding means is elastically pressed by the first engagement member (second engagement member) pressing the second engagement member (first engagement member). A gaming machine 5 that is configured to engage in a deformed state. In addition, you may comprise so that both the members of a 1st and 2nd engagement member may engage in the state elastically deformed mutually.

  According to the gaming machine 5, the first engagement member (second engagement member) is configured to engage with the second engagement member (first engagement member) in a state of being elastically deformed by pressing. Therefore, both members can be firmly engaged without rattling, and as a result, it is possible to more reliably suppress the widening of the gap between the opposing surfaces of the protection plate and the game board. In addition, for example, the front door rattles against the main body due to dimensional tolerance in manufacturing of the opening / closing shaft or wear due to use, and as a result, the gap between the opposing surfaces of the game board and the protective plate is rattled. Even when the first engagement member or (and) the second engagement member is engaged, rattling against the main body of the front door can be absorbed by the elastic deformation when the first engagement member or (and) the second engagement member is engaged. The distance between the opposing surfaces of the protective plate can be kept constant.

  In any one of the gaming machines 1 to 5, a taper is provided at a distal end of an engagement surface where the first engagement member (second engagement member) engages with the second engagement member (first engagement member). A gaming machine 6 in which a guide surface is formed. The guide surface may be formed on each of the first and second engaging members.

  According to the gaming machine 6, since the tapered guide surface is formed at the tip of the engagement surface of the first engagement member or (and) the second engagement member, the first engagement member (second The engagement surface of the engagement member) can be properly guided to a predetermined position, and can be reliably engaged with the engagement surface of the second engagement member (first engagement member).

  In any one of the gaming machines 1 to 6, the main body includes an inner frame disposed on a front side of the game board, and the second engagement member of the interval holding unit is attached to the inner frame. A gaming machine 7 that is made of a material that is stronger than the inner frame. The high-strength material means that the rigidity strength is higher as in the case described above. For example, when the inner frame is made of a resin material, the second engagement member is made of a metal material (iron, The case where it comprises with aluminum or stainless steel etc. is illustrated.

  According to the gaming machine 7, the second engagement member is made of a material having a strength higher than that of the inner frame, and the rigidity strength thereof is secured, so that the upper plate or the like is drawn to the player and the first engagement is performed. Even when an external force is received from the member, it is possible to prevent the opposing surface interval between the protective plate and the game board from being widened against the external force. Further, as described above, since the engaging portion with the first engaging member is formed by attaching another member (second engaging member) to the inner frame, the engaging portion (second engaging member) is formed. Compared with the case where the inner frame is molded integrally with the inner frame, the inner frame itself does not need to be molded into a complicated shape, so the molding cost can be reduced correspondingly, and the degree of freedom in design increases. Therefore, it can be formed in a higher strength shape.

  In the gaming machine 7, the second engaging member attached to the inner frame is directly or indirectly connected to the gaming board 8. The direct connection is, for example, that the end of the second engagement member attached to the inner frame (for example, screwing, bonding, fitting, etc.) is extended to the game board and extended. A case where the part is also attached to the game board (for example, screwing, bonding, fitting, etc.) is exemplified. The indirect connection is exemplified by a case in which a screw for screwing the second engagement member to the inner frame is also screwed to the game board at the same time.

  According to the gaming machine 7, for example, the front frame that is grabbed by the player and pulled toward the front is bent, and the protective plate attached to the front frame is interlocked with the deformation of the front frame. Even when the first engaging member and the second engaging member engaged with the first engaging member are displaced in the deformation direction of the front frame, the second engaging member is directly connected to the game board. Or since it is connected indirectly, a game board is also displaced to the deformation | transformation direction of a front frame with a 2nd engagement member. Therefore, since the game board and the protective plate are relatively displaced in the same direction while the distance between the opposing surfaces is kept constant, it is effective that the distance between the opposing surfaces of the game board and the protective plate is widened. Can be suppressed.

  In any one of the gaming machines 1 to 6, the gaming machine 9 is characterized in that the second engagement member of the interval holding means is attached to the gaming board. According to the gaming machine 9, for example, the front frame that is grabbed by the player and pulled toward the front is bent, and the protection plate attached to the front frame is interlocked with the deformation of the front frame. Even if the first engaging member and the second engaging member engaged with the first engaging member are displaced in the deformation direction of the front frame, the second engaging member is attached to the game board. Since it is worn, the game board is also displaced in the deformation direction of the front frame together with the second engagement member. Therefore, since the game board and the protective plate are relatively displaced in the same direction while the distance between the opposing surfaces is kept constant, it is effective that the distance between the opposing surfaces of the game board and the protective plate is widened. Can be suppressed.

  In the gaming machine 4 or 5, the first engagement member and the second engagement member of the gap holding unit are disposed at least on the front door and the opening / closing axis side of the main body with respect to the intermediate position in the width direction of the front door and the main body. A gaming machine 10 that is characterized by

  According to the gaming machine 10, since the first and second engaging members are disposed closer to the opening / closing axis than the intermediate position in the width direction of the front door and the main body, according to the lever principle, the opening / closing axis serves as a fulcrum. A swing moment that is at least twice the swing moment applied by the opening / closing operation can be applied to the first and second engaging members, and as a result, the first and second engagements can be performed with a smaller opening / closing operation force. The member can be securely engaged (while elastically deforming).

  In any one of the gaming machines 1 to 10, the first engagement member and the second engagement member of the gap holding unit are supported by the main body so that the front door can be opened and closed in the height direction of the front door and the main body. The gaming machine 11 is characterized in that at least one or more shafts are arranged between the two open / close shafts. When three or more open / close shafts are provided, it is preferable to dispose at least one or more first and second engagement members between any two open / close shafts, more preferably all three or more. At least one or more first and second engaging members are disposed between the opening and closing shafts.

  According to the gaming machine 11, since at least one or more of the first and second engaging members of the interval holding means are provided between the two opening and closing shafts, the gap between the opposing surfaces of the game board and the protection plate is further widened. It can be effectively suppressed. That is, since the front door (front frame) is connected to the main body by the opening / closing shaft, for example, when the player holds the upper plate or the like and draws it toward the front, the front frame is attached to the opening / closing shaft. The part corresponding to the middle part will bend more greatly. Therefore, by providing the first and second engaging members between the two opening and closing shafts in order to suppress the deformation of this portion, it is possible to more effectively suppress the widening of the gap between the opposing surfaces of the game board and the protection plate. Can do.

  In any one of the gaming machines 1 to 11, at least one or more of the first engaging member and the second engaging member of the interval holding unit are provided in the vicinity of an upper plate provided integrally with the front door. A gaming machine 12 characterized by that. Note that the vicinity of the upper plate means that the height direction positions of the front door and the main body substantially coincide with the upper plate, and is necessarily provided at a position corresponding to the upper plate (overlaps with the upper plate) in front view of the front door. There is no need.

  According to the gaming machine 12, since at least one or more of the first and second engaging members of the interval holding means are provided between the two open / close shafts, the gap between the opposing surfaces of the game board and the protection plate is further increased. It can be effectively suppressed. That is, the front door (front frame) is generally pulled by the player after the upper plate is gripped by the player, so that the front frame is deformed by providing the first and second engaging members in the vicinity of the upper plate. As a result, it is possible to effectively suppress the widening of the gap between the opposing surfaces of the game board and the protection plate.
