Description

  The present invention relates to a gaming machine represented by a pachinko machine.

There is a gaming machine configured such that a game ball is supplied on a launch rail and the game ball is launched toward a game area by a game ball launching device.
Examples of the gaming machine having such a configuration include the following.

JP2007-201173.

In the gaming machine configured as described above, for example, when a game ball is supplied onto the firing rail from an upper position on the side opposite to the base plate in which the side wall is disposed in the vicinity of the side of the firing rail, the launch rail is caused by the momentum of the fall For example, when the launch rail is formed of a relatively soft metal, the side wall is shaved, and the shaving dust accumulates on the launch rail and distorts the trajectory of the game ball. There is a problem in that it collides with the side wall and bounces, reaches the launch standby position in an unstable posture, and the trajectory is not fixed when it is launched by the hitting ball portion, and does not become the hit ball as expected by the player.
In addition, the firing rail is often formed in a V-groove shape or a U-groove shape, for example, so as to be guided while holding the game ball with a small number of contacts (two or three points). In some cases, even a gaming machine designed to be supplied with a game ball from directly above the launch rail may cause a slight deviation in the supply position caused by deformation of a member such as a ball feed mechanism. It is possible that the game ball jumps.

  The present invention has been devised in view of such a problem, and when supplying a game ball on the launch rail, the base plate of the game ball launcher is not scraped and fired in a stable posture at an early stage. An object is to allow a ball to sit well at a standby position so that a game ball can be launched in a desired locus.

In order to achieve the above object, the gaming machine according to the present invention includes means 1 as follows:
A launch rail is provided close to the surface of the base plate of the game ball launcher, and a game ball is supplied onto the launch rail from an upper position opposite to the base plate, and the game ball is sent by the game ball launcher. A gaming machine configured to launch toward a gaming area,
The first impact absorbing member is arranged on the base plate from the position where the supplied game ball is received to the rear waiting position for firing, among the firing rails.
It is characterized by that.
With this configuration, when a game ball is supplied to the launch rail, if the game ball is dropped and supplied obliquely from an upper position opposite to the base plate of the game ball launcher, the game ball is launched. While colliding with the rail, it will collide with the base plate on the opposite side with excessive momentum. By arranging the first shock absorbing member at this position, the collision energy is absorbed, and the game ball moves on the launch rail. It is possible to avoid dancing, and immediately settle down to the launch standby position in a stable state. As a result, the ball sitting of the game ball can be improved, the game ball launching device can be launched with a stable posture at all times, the trajectory of the game ball is stabilized, and the game ball can be launched at the position intended by the player. It is possible to reduce the foul sphere.
And until now, game balls (usually steel balls) collide with the base plate (usually aluminum alloy), the base plate is shaved, dust is generated and accumulates on the firing rail, and the firing state may deteriorate. However, these problems are solved.
Of course, the situation where the dance of the game ball is further promoted by cutting the base plate can be avoided.

In the present invention, the game area refers to an area surrounded by, for example, an outer rail and an inner rail.
Further, the position of the launch rail that receives the supplied game ball refers to a place where the game ball is supplied onto the launch rail from an upper position opposite to the base plate of the game ball launcher, for example.
The launch standby position refers to, for example, a position where the game ball is stopped just before the launch action (striking). Specifically, it refers to the position where the game ball is stopped and held by the lower end of the launch rail and the ball waiting member thereabove.
Further, the shock absorbing member is a buffer material that reduces the impact, and whether or not to reduce the impact may be specified by a leaf, for example, a material. The buffer material in this case is made of a material having low rebound resilience that absorbs an impact force, and examples thereof include a vibration damping rubber, an elastomer, or a similar material. In addition, a softer material than the base plate may be used as the buffer love material.

In order to achieve the above object, the gaming machine according to the present invention provides the means 2,
A ball feeding mechanism for delivering a predetermined number of game balls, a game ball launching device that launches game balls toward a game area, and a game ball from a launch standby position where the game ball waits to receive a hitting operation by the game ball launching device A launch rail that has an inclined surface that is inclined upward in the direction in which the game ball is launched by the launching device, and that receives the game ball supplied by the ball feed mechanism upstream of the firing standby position of the inclined surface; And the game ball supplied by the ball feeding mechanism moves to the launch standby position along the inclined surface, and the game ball launched by the game ball launcher at the launch standby position follows the inclined surface. And the inclined surface has two surfaces that support the lower half of the game ball from both sides and are open upward. A game machine is formed,
A base plate to which the launch rail is attached so that the surface is along the side of the launch rail, and from the position where the game ball supplied by the ball feed mechanism is received from the launch rail to the launch standby position; A first shock absorbing member for reducing the shock when a game ball comes into contact is disposed at a predetermined position on the surface along the gap.

 With this configuration, when the inclined surface of the launch rail supports the lower half of the game ball, the resistance when the game ball is launched by the game ball launcher can be reduced and stable launch can be achieved. Although it can be made easier, there is a risk that the rampage of the game ball supplied on the launch rail will be prolonged accordingly. By adopting the configuration of the present invention, when a game ball rampaged on the launch rail comes into contact with the impact absorbing member, the impact can be mitigated, and the game ball rampage can be reduced to realize stable launch. Will be able to.

Mean 3: In the gaming machine of means 1 or means 2,
The base plate is provided with a main opening, and the first shock absorbing member is constituted by an impact absorbing portion into which the main opening is fitted, and an attachment portion for attaching to the base plate. It is attached to the back surface of the base plate.
Thus, the first shock absorbing member is composed of the shock absorbing portion and the mounting portion, and the whole is larger than the shock absorbing portion, and is attached by the mounting portion from the back surface of the base plate. There is an advantage that the attachment site becomes a wrinkle and is difficult to peel off.

Means 4: In the gaming machine of means 1 to means 3,
The base plate is provided with at least one fastening opening apart from the main opening, and a projection to be fitted into the fastening opening is provided at a mounting portion of the first shock absorbing member. It is characterized by.
In this way, the base plate is provided with at least one fastening opening, and the mounting portion is provided with a protrusion that fits into the fastening opening, thereby fitting the first shock absorbing member. It can be fastened to the base plate by a joint means, and can be easily attached and detached without using screws or the like.
Of course, if there are a plurality of fastening openings and a plurality of the projections, a more robust and stable attachment can be achieved.

Means 5: In the gaming machine of means 3 or means 4,
At least one mounting hole is provided in a mounting portion of the first shock absorbing member, and an engagement protrusion that is fitted into the mounting hole is provided in the base plate.
In this way, at least one mounting hole is provided in the mounting portion, and the base plate is provided with an engagement protrusion to be fitted thereto, whereby the first shock absorbing member is fitted to the base plate by the fitting means. It can be easily attached and detached without using screws or the like.
Of course, if there are a plurality of mounting holes and a plurality of the engaging projections, a more robust and stable mounting can be achieved.
Further, when the at least one fastening opening portion of the base plate and the fitting means by the protrusions fitted into the fastening opening portion are used in combination, a more firm attachment can be performed.

Means 6: In the gaming machine of means 1 to means 5,
The lower part of the lower end of the launch rail is opened to allow the game ball to fall, and a ball waiting member is provided above the lower end part with a predetermined height H, so that the game ball is fired. The horizontal distance L and the height H between the initial position P0 of the tip of the hitting portion of the apparatus and the lower end of the firing rail are set to be the same length, or the horizontal distance L is set to be longer. It is characterized by that.
With this configuration, when a game ball having a smaller diameter than a predetermined size is illegally used for the purpose of increasing the winning rate, the game ball is supplied onto the launch rail. If it is done, it will not be received by the ball waiting member, but will pass through here and exceed the lower end of the firing rail. At that time, the horizontal distance L and the height H between the initial position P0 of the tip of the hitting portion of the game ball launching device and the lower end of the firing rail are the same length, or the horizontal distance L is longer. Therefore, the game ball is sandwiched between the hitting ball portion of the game ball launching device and the lower end portion of the launch rail, or falls downward from the lower end portion of the launch rail. As a result, an illegal small-diameter game ball is not normally launched, and an illegal game using such a small-diameter game ball can be avoided in advance.

Means 7: In the gaming machines of means 1 to means 6,
A ball feeding mechanism for supplying game balls to the firing rail is provided above the side of the firing rail, and a second shock absorbing member is provided at a position facing the first shock absorbing member of the ball feeding mechanism. It is characterized by.
As described above, the second impact absorbing member is provided at a position facing the first impact absorbing member of the ball feeding mechanism, so that it is supplied onto the firing rail and collides with the first impact absorbing member. When the game ball is not able to sufficiently absorb the impact force, it is repelled on the opposite side, but the second impact absorbing member is provided on the opposite side ball feed mechanism. The collision energy can be absorbed again, and the game ball can be stably settled at the launch standby position. Thereby, the ball sitting of the game ball can be further improved.

Means 8: In the gaming machines of means 1 to means 7,
The main opening has a large width in the vertical direction at the upper end side of the firing rail and a lower width at the lower end side, and the shock absorbing portion of the first shock absorbing member fitted therein The main opening is formed in the same shape as that of the main opening.
As described above, the shape of the shock absorbing portion of the first shock absorbing member is such that the upper end side of the firing rail has a large width in the vertical direction and the lower end side has a smaller width than that, so that the game ball In the position where the drop is supplied obliquely from above, the fall energy is large and the dance caused by jumping is large, so it is necessary to cover this sufficiently, and it is not a simple rectangle or circle but the above-mentioned large enough It is possible to further suppress the dancing of the game ball by making it an irregular shape.

Means 9: In the gaming machines of means 3 to 8,
The firing rail is formed such that a cross section in a direction perpendicular to the direction in which the game balls are fired has an M shape, and a shock absorbing portion of the first shock absorbing member is formed on a base plate corresponding to the top of the M shape. It is located in the part.
In this way, when the launch rail is formed so that the cross section in the direction orthogonal to the launch direction of the game ball has an M shape, the game ball supplied from above onto the launch rail is the inside of the M shape. Since it will collide with the slope, it will collide with the side wall of the base plate beyond the top of the M shape by climbing this slope, and the side wall portion of the base plate beyond the top of the M shape By providing the shock absorbing portion of the first shock absorbing member, the ball seating action becomes even more effective for the launch rail having such a shape.

According to the present invention, by arranging the first impact absorbing member on the base plate of the game ball launching device, the collision energy against the base plate at the time of supply of the ball game ball is absorbed, and the game ball dances on the launch rail. And immediately settle down to the launch standby position in a stable state, so that the ball sitting of the game ball can be improved, and the game ball launcher can always be launched in a stable posture. The trajectory is stable, the game ball can be launched at the position intended by the player, and the foul ball can be reduced.
And until now, the base plate has been scraped off by the game ball, dust is generated and collected on the launch rail, and the launch state has deteriorated, but there is also an advantage that such a problem is solved.
Other advantages will be apparent from the following description.

  Hereinafter, embodiments of a gaming machine according to the present invention will be described with reference to the drawings. In the following embodiments, a pachinko machine will be described for the sake of convenience. However, the present invention uses a ball ball game machine other than the pachinko machine (for example, an arrange ball machine, a sparrow ball game machine, etc.), and other game balls. The present invention can be applied to various types of gaming machines.

(Front configuration of pachinko machine)
FIG. 1 is a front view of the pachinko machine 10 according to the present embodiment, FIG. 2 is a perspective view from the front of the pachinko machine 10, and FIG. 3 is a perspective view of the front frame 14. 4 is a perspective view of the state in which the front frame 14 is opened, FIG. 5 is a front view of the state in which the front frame 14 is opened, and FIG. 6 is a front view of the game board 30.

As shown in FIGS. 1 to 6, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 that is supported on one side of the outer frame 11 so as to be openable and closable. I have. The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. The outer frame 11 may be made of light metal such as resin or aluminum in order to reduce the weight.
The opening / closing axis of the inner frame 12 is set so as to extend vertically on the opposite side of the game ball launching handle 18 (left side of the pachinko machine 10 in FIG. 1) as viewed from the front of the pachinko machine 10. The inner frame 12 can be sufficiently opened to the front side with the axis as the center. The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. By doing so, the advantages of high viscosity and high impact resistance and low cost production are exhibited.

  The lower plate unit 13 is fixed to the inner frame 12 with a fastener such as a screw. On the front side of the lower plate unit 13, there are provided a lower plate 15, a ball release lever 17, a game ball launching handle 18, an ashtray 22, and a sound output port 24 (positions on the left and right upper ends of the inner frame 12). The lower tray 15 serving as a ball receiving tray is provided at a substantially central portion of the lower tray unit 13 and serves to stop a game ball discharged from the outlet 16 when the upper tray 19 described later becomes full. There is. The ball removal lever 17 is for removing a game ball in the lower plate 15. By moving the ball removal lever 17 to the left in FIG. 1, a predetermined position on the bottom surface of the lower plate 15 is opened, The game ball stopped in the tray 15 can be discharged through the opening on the bottom surface of the lower tray 15 to the player's ball storage box (dollar box).

The game ball launching handle 18 is disposed so as to protrude to the front side on the right side of the lower plate 15. In accordance with the operation of the game ball launch handle 18 by the player, the game ball is driven toward the game board 30 by the game ball launch device 38 (see FIG. 4). The game ball launcher 38 includes a game ball launch handle 18, a set handle, a launch motor, and the like, which will be described later.
The sound output port 24 is an output port for outputting sound from a speaker provided at the position of the upper left and right ends of the inner frame 12. Moreover, the ashtray 22 is provided on the left side of the lower tray 15 as shown in FIG. The ashtray 22 is supported so as to rotate (for example, forwardly toward the front side) about an axis line in the left-right direction (horizontal direction).

  Note that most of the lower dish unit 13 is molded of ABS resin in the same manner as the inner frame 12. By doing so, it is highly viscous and resistant to impact, and can be manufactured at low cost. In particular, the surface layer forming the lower plate 15 and the front panel portion at the back of the lower plate 15 are molded from flame-retardant ABS resin. For this reason, this part is hard to burn.

As shown in FIG. 4, the front frame 14 is attached to the inner frame 12 so as to be openable and closable. Like the inner frame 12, the front frame 14 has an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10. It can be opened forward with the heart. Moreover, the front frame 14 is attached so as to fit into the outer wall (rib) 12 b of the inner frame 12.
That is, since at least a part of the side surface of the front frame 14 is attached so as to fit into the outer wall (rib) 12b of the inner frame 12, foreign matter (needle-like shape) is formed from the gap between the inner frame 12 and the front frame 14. Or, it is a thin plate or the like, and specifically, it is possible to prevent illegal acts such as inserting a wire, a piano wire, a celluloid plate, etc.). Further, since the front frame 14 is made of a synthetic resin, specifically, an ABS resin, like the inner frame 12, the front frame 14 is highly viscous and resistant to impact, and can be manufactured at low cost.

  On the other hand, an upper plate 19 (see FIG. 1) as a receiving tray for game balls is provided integrally with the front frame 14 at a lower portion of the front frame 14 (above the lower plate 15 described above). The upper tray 19 is a ball receiving tray for temporarily storing the game balls and guiding them to the game ball launching device 38 while aligning them in a line. Similar to the lower plate 15, the upper plate 19 has a structure in which the surface layer is formed of flame-retardant ABS resin.

As shown in FIG. 4, the inner frame 12 is mainly configured by a resin base 20 having a rectangular outer shape, and a substantially circular window hole 21 is formed at the center of the resin base 20.
A game board 30 shown in FIGS. 4 to 6 is detachably mounted on the rear side of the resin base 20. As shown in FIG. 6, the game board 30 is made of a rectangular plywood, one corner of the upper part is dropped (described later), and its peripheral edge abuts against the back side of the resin base 20 (inner frame 12). It is attached in the state.

  Accordingly, a substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the inner frame 12 through the window hole 21 of the resin base 20 (FIG. 4 shows an out port 36 of the game board 30). ing). And here, a corner (corner) close to a pivoting portion of the game board 30 with respect to the outer frame 11 of the inner frame 12 (a pivoting centering on an opening / closing axis extending vertically to the left side when viewed from the front of the pachinko machine 10). However, as shown in FIG. 6, the corner is dropped (notched) 720 in a substantially triangular shape (the notch is an arc line but becomes a substantially triangular notch).

Next, the configuration of the game board 30 will be described with reference to FIG. FIG. 6 is a front view showing the configuration of the game board 30. Two pairs of general winning ports 31, 31 are arranged in a stepped manner at a slightly lower position on the left and right of the game board 30, and a starting port 33 is arranged at the lower center. The general winning ports 31, 31 and the starting port 33 are openings that penetrate from the game area toward the back surface, and a winning device is attached to correspond to these openings. That is, a ball detection sensor corresponding to these is provided on the back surface of the game board 30, and these sensors are connected to a main control board (main control device) to be described later through an electric wiring (not shown). .
When a game ball enters the general winning openings 31, 31 and the start opening 33, it is detected by the detection sensors, and based on the output of the detection sensors, the upper plate 19 (or the lower plate 15). When a predetermined number of prize balls are paid out and a game ball enters the start port 33, a lottery to be described later is started.

The detection results detected by the winning detection sensors are taken into a main control board, which will be described later, and a payout command (the number of game balls to be paid out) according to the winning situation is paid out from the main control board. Sent to the board. Then, a predetermined number of game balls are paid out by the output of the payout control board.
In such a case, a conventional method (so-called evidence ball method) in which game balls won in various winning openings are once collected in a winning ball processing device and paid out after the winning ball processing device confirms the presence of winning balls one by one in order. Unlike the above, in the pachinko machine 10 according to the present embodiment, the winning of a game ball is electrically detected for each winning opening and the payout is immediately made (that is, the winning ball processing apparatus is abolished in the pachinko machine 10). is doing). Therefore, even if there are a lot of game balls to be paid out, the payout can be carried out quickly. However, the conventional “evidence ball system” may be applied to the present invention.

In addition, a decorative symbol display device 42 using a liquid crystal panel is disposed at the center of the game board 30, and through gates 34, 34 are disposed on the left and right side portions thereof. These through gates open and close the wings of the starting port 33 described later by passing the game ball.
In addition, a decorative member 35 having the above-described general winning ports 31 and 31 is provided at the lower left and right positions of the game board 30, and an out port 36 is provided at the lower part of the game board 30. A game ball that has not entered the apparatus or the like is guided through the out port 36 toward a ball discharge path (not shown) on the back of the game board 30. Further, the game board 30 is provided with a large number of guide nails for appropriately dispersing and adjusting the falling direction of the game balls, and a windmill having the same function.

  Further, the game board 30 is provided with a rail unit 50 for guiding the game ball launched from the game ball launching device 38 to the upper part of the game board 30, and is launched in accordance with the turning operation of the game ball launch handle 18. The played game balls are guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product (for example, a molded product added with fluororesin), and has an inner rail 51 and an outer rail 52 that are integrally formed in an inner and outer double. .

In addition, since the rail unit 50 is shape | molded by adding a fluororesin, it can reduce the frictional resistance of a game ball. The inner rail 51 is formed in a substantially annular shape except for about ¼ of the upper portion, and an outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51.
In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a spherical guide passage is formed by a portion (the left portion facing) where the rails 51 and 52 are parallel to each other at a predetermined interval. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip portion of the inner rail 51 (upper left portion in FIG. 6). This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 51 and the outer rail 52 to the upper part of the game board 30 returns to the ball guide path again. Yes. Further, a return rubber 54 is attached to the outer rail 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 6: a portion corresponding to the tip portion of the outer rail 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back. On the inner side surface of the outer rail 52, a sliding plate as a long metal strip made of stainless steel is attached to make the flight of the game ball smoother, that is, to reduce the frictional resistance of the game ball. It is worn.

  An arc-shaped flange 56 projecting outward is formed on the outer peripheral portion of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, screws or the like are inserted into a plurality of through holes formed in the flange 56. The rail unit 50 is fastened to 30.

A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail 51 and the outer rail 52 so as to close a part of the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail 51 to the lower end portion of the rail unit 50, and serves to guide the foul ball that does not reach the game area and flows backward in the ball guide passage to the foul ball passage. .
Note that the lower right corner and the lower left corner of the game board 30 are spaces for sticking stickers (S1 and S2 in FIG. 6) and plates such as stamps (for example, serial numbers are described). In order to secure this adhering space, notches 58 and 59 are formed in the flange 56. By sticking a sticker such as a certificate (S1, S2 in FIG. 8) to the lower right corner or the lower left corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape by the inner periphery (inner and outer rails) of the rail unit 50. In the present embodiment, the game area is an area excluding the area of the guide rail that is a parallel part of the inner and outer rails 51 and 52 among the area surrounded by the inner rail 51 and the outer rail 52 when viewed from the front of the pachinko machine 10. It is said.
Accordingly, since the game area does not include the guide rail portion, the left limit position toward the game area is specified not by the outer rail 52 but by the inner rail 51. Similarly, the right limit position toward the game area is specified by the inner rail 51. The lower limit position of the game area is specified by the lower end position of the game board 30. Further, the upper limit position of the game area is specified by the outer rail 52.

  In the resin base, below the window hole 21 (game board 30), a launch rail 170 for guiding the game ball immediately after being launched from the game ball launching device 38 is attached. The firing rail 170 is attached and fixed to the resin base 172 via a base plate 171 (a member for attaching the game ball launching device 38) which is a metal plate (here, an aluminum alloy) behind the firing rail 170, and a predetermined launch. It is configured to extend linearly at an angle (launch angle). This configuration will be described in detail later based on FIG. Accordingly, the game ball that is launched in accordance with the turning operation of the game ball launching handle 18 is first launched obliquely upward along the launch rail 170, and thereafter, into the predetermined game area through the ball guide path of the rail unit 50 as described above. Guided.

  Further, there is a gap of a predetermined interval between the firing rail 170 and the rail unit 50 (guidance rail), and a foul ball passage is formed below the gap. Therefore, if the game ball launched from the game ball launching device 38 does not reach the return ball prevention member 53 and returns to the inside of the guide rail as a foul ball, the foul ball passes through the foul ball passage 15 to the lower plate 15. To be discharged.

  When the foul spheres flow backward in the guide rail, most of them flow along the outer rail 52 and drop downward when reaching the lower end of the outer rail 52. However, some foul spheres fall inside the guide rail. There is also a thing that jumps to the inner rail 51 side. At this time, the splashed foul ball hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage. As a result, all of the foul balls are reliably guided to the foul ball passage. Interference between the ball and the next-launched game ball is suppressed.

  As will be described in detail later with reference to FIG. 13 and the like, the game ball launcher 38 has one game ball from the ball outlet on the front frame 14 side (the ball outlet leading from the most downstream portion of the upper plate 19). The ball lever 173A provided to the ball feed mechanism 173 is operated by the solenoid 173C to supply the game balls one by one onto the firing rail. Further, the game ball launcher 38 is provided with a rhinocele-shaped conical hitting portion 38A made of synthetic resin and fixed to the tip of the shaft portion 38B, and the game is accompanied by the piston movement of the hitting portion 38A by excitation of the solenoid. A ball is fired.

  A reference numeral 67 in FIG. 4 is a discharge port communicating with the upper plate 19, and the game ball is discharged to the upper plate 19 through the discharge port 67. The discharge port 67 is provided with an openable / closable shutter that is displaced in a substantially horizontal state and a substantially vertical state about a rotation axis in a substantially horizontal direction, and has a state in which the front frame 14 is opened from the inner frame 12. In the state of FIG. 4, the shutter is changed from a substantially horizontal state to a substantially vertical state by an urging force of a spring or the like, and the discharge port 67 is closed so that the game ball does not spill from the discharge port 67.

  Further, when the front frame 14 is closed, the shutter is pushed open by a ball passage rod 69 (see FIG. 4) provided on the back surface of the front frame 14 to be in a substantially horizontal state and discharged toward the discharge port 67. The played game balls are discharged to the upper plate 19 through the ball passageway 69 without any leakage. Therefore, in the pachinko machine 10, it is possible to prevent the inconvenience that the game ball in the payout passage or the like spills out of the pachinko machine 10 when the front frame 14 is opened.

  As shown in FIG. 4, a front frame set opening detection switch 90 that detects that the front frame 14 is opened with respect to the inner frame 12 is provided on the upper side of the inner frame 12. When the front frame 14 is opened, it is output from the front frame set open detection switch 90 to the computer for the hall (in the pachinko parlor). Further, when the front frame 14 is closed, the metal reinforcing plate of the front frame 14 comes into contact with the pair of metal fittings of the inner frame 12, and the grounding of the front frame 14 is ensured.

Here, the front frame 14 described above will be described in more detail with reference to FIGS. 1 to 6.
A substantially oval window 101 is formed on the front frame 14 so that most of the game area can be viewed from the outside. Specifically, the base member includes an opening that forms the window portion 101, and a substantially central portion on the left and right sides thereof has a shape that is curved and thinned relatively gently as compared with the upper and lower sides. The substantially central portion may be linear.

In addition, the front frame 14 is provided with a light emitting portion such as various lamps as one of the effect devices 700 around the periphery (for example, a corner portion). These light emitting units play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state in the big hit game state or when the blade is opened. For example, at the periphery of the window portion 101, an annular illumination portion 102 incorporating a light emitting portion such as an LED is provided symmetrically, and at the center of the annular illumination portion 102 and at the top of the pachinko machine 10, Similarly, a central illumination unit 103 having a built-in light emitting unit such as an LED is provided.
In the pachinko machine 10, the central illumination unit 103 functions as a jackpot lamp, and lights and blinks during the jackpot gaming state to notify that the jackpot gaming state is in progress. In addition, an upper plate illumination unit 104 having a built-in light emitting unit such as an LED is also provided around the upper plate 19.

  In addition, on the left and right sides of the central illumination unit 103, there are provided a prize ball lamp 105 that is lit during the payout of the prize ball and error display lamps 810 and 813 (LED: which will be described later) that are lit when a predetermined error occurs. . Further, a small window portion 107 made of a transparent resin is provided so as to be able to visually recognize a part of the inner frame 12 surface, the game board 30 surface, and the like so as to be adjacent to the lower end portion of the annular illumination portion 102. Since the predetermined portion of the small window portion 107 has a flat shape, the stamp attached to the lower right corner portion of the game board 30 can be suitably read from the flat portion of the small window portion 107 by a machine. Furthermore, although there are electrical lamps and LEDs for a prize opening etc. in the game area, such a light emitting unit also constitutes a part of the effect device 700.

  Further, as shown in FIG. 1, a ball rental operation unit 120 is disposed below the window unit 101, and the ball rental operation unit 120 is provided with a ball rental button, a return button, and a frequency display unit.

Done. The ball lending button is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. The The return button is operated when requesting the return of a card or the like inserted into the card unit.

  The frequency display unit displays remaining amount information such as a card. Note that the ball lending operation unit 120 is not necessary for a pachinko machine in which a game ball is directly rented from the ball lending device unit to the upper plate 19 without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

(Back view of pachinko machine)
7 and 8 are a rear view of the pachinko machine 10 and a perspective view in which the set plate 400 is partially opened.

  The second control board unit 202 has a configuration in which an audio lamp control device is mounted on a pedestal, is disposed at a position covering the back side of the decorative symbol display device 42, and is attached to the game board 30. The audio lamp control device includes an audio lamp substrate.

  The third control board unit 203 includes a payout control device 311, a launch control device 312, a power supply control device 313, and a card unit connection board 314. The payout control device 311, the launch control device 312, and the power supply control device 313 are equipped with a control board including a central control CPU, ROM, RAM, various ports and the like as is well known. The payout of prize balls and rental balls is controlled.

  Further, the launch control device 312 controls the launch motor in accordance with the operation of the game ball launch handle 18 by the player, and the power supply control device 313 generates and outputs a predetermined power supply voltage required by various control devices. The card unit connection board 314 is electrically connected to the ball lending operation unit 120 (see FIG. 1) on the front surface of the pachinko machine and a card unit (not shown), and receives a ball lending operation command by the player and pays it out. Is output. Note that the card unit connection board 314 is unnecessary in a cash machine in which game balls are lent directly to the upper plate 19 from a ball lending device or the like without using a card unit.

  The payout control device 311, the firing control device 312, the power supply control device 313, and the card unit connection substrate 314 are respectively connected to a substrate case 315 (another substrate case located inside) 316 and 318 made of a transparent resin material or the like. The third control board unit 203 is configured together with a dispensing unit having a generally inverted L shape disposed from the top to the side of the set plate 400 and a discharge passage board disposed at the bottom. .

Here, the description regarding the said launch control apparatus 312 is given in detail.
The launch control device 312 includes a launch control circuit. The launch control circuit is responsible for launch control of the launch solenoid in accordance with the operation of the game ball launch handle 18 by the player, and the launch solenoid is driven when predetermined launch conditions are met. Specifically, the launch control circuit is connected to a launch switch, a touch sensor, and a stop switch provided on the game ball launch handle 18, and the launch switch and the touch sensor are on and the stop switch is off. Only when this happens, the firing permission signal is output to the control board 80 (via the power supply monitoring board) of the main controller 261. The control board 80 outputs a firing control signal (5-volt pulse signal) with a predetermined period to the firing control circuit based on the input of the firing permission signal. The firing control circuit is provided with an amplifier (FET), and whenever the firing control signal is input, the amplifier instantaneously supplies the power stored in the capacitor (for example, the power supply of 32 volts is supplied). To drive the launch solenoid. In this case, the game ball launching handle 18 is provided with a dial variable resistor for determining the handle operation amount, and the launch control circuit is charged in the capacitor based on the change in the resistance value in the dial variable resistor. The launching speed by the firing solenoid is determined by adjusting the amount of power supply.
Further, in the control device 80, as normal processing, external output processing for outputting various commands to other control boards, processing for updating various counters, command setting processing, processing for opening / closing the special prize opening according to the hit state, game Ball launch control processing and the like are sequentially executed. Among these, the game ball launch control process is executed every 4 msec (every normal process).

 In the game ball launch control process, first, the launch counter is incremented by 1, and then it is determined whether or not the incremented launch counter value is 150 or more. In such a case, a time of 0.6 sec is required while the firing counter reaches 0 to 150. In this step, when the value of the firing counter HC is less than 150, the present process is terminated as it is, and when the value of the firing counter HC is 150 or more, the firing counter is cleared to zero. Next, it is determined whether or not a launch permission flag is set in the launch permission flag storage area of the RAM. The launch permission flag is a flag that is set when a launch permission signal is output from the launch control device 312. If the firing permission flag has been set, a firing control signal is output to the firing control device 312, and if the firing permission flag has not been set, the process ends without outputting the firing control signal. In such a case, the firing control signal may be output on condition that the CR unit is connected without failure. The launch control device 312 inputs one launch control signal, thereby exciting the launch solenoid once and launching one game ball. That is, in the pachinko machine 10, the game ball is fired on condition that the player is operating the game ball launch handle 18. Further, as described above, since a time of 0.6 sec is required while the launch counter reaches 0 to 150, basically, the launch control signal is output 100 times per minute, and 100 per minute. A game ball is fired. Note that, as described above, the control board 80 controls the permission for launching the game ball because the main part of the game in the pachinko machine 10 that is the launch of the game ball is under the control of the control board 80. It is.

  As shown in FIG. 7, the payout control device 311 is provided with a state return switch 321. For example, when the state return switch 321 is pressed when a payout error occurs, such as a ball jam in the payout motor unit, the payout motor is rotated forward and reverse so that the ball clogging is eliminated (return to the normal state). It has become. The power supply control device 313 is provided with a RAM erase switch 323.

  As shown in FIG. 4, the corner of the game board 30 close to the pivoting portion 725 of the inner frame 12 with respect to the outer frame 11 is substantially triangular as shown in FIG. 6 (the center side of the game board is arcuate). ) Is 720.

A rectangular locking piece 517 formed with claws is disposed so as to protrude rearward (to the first substrate case 201A side), while a rectangular protrusion is formed on the free end of the first substrate case 201A. The portion 851 is disposed so as to protrude laterally (leftward in FIG. 10), and the locking piece 517 can be elastically locked to the protruding portion 851. The locking piece 517 is integrally formed with a spacer (intermediate member) 501. The locking piece 517 is used to maintain a closed state when the spacer (intermediate member) 501 is opened and closed.

  As described above, the spacer (intermediate member) 501 is interposed between the back surface of the game board 30 and the first control board unit 201, so that the back surface of the game board 30 and the first control board unit 201 are connected. The gap between the gaps is compensated for, so that a space that can be fraudulent is not formed. Furthermore, since this spacer (intermediate member) 501 is fixed in a state of being sealed by the sealing means 520, it is difficult to remove it illegally, even if this seal is illegally broken. Since the traces remain, it is obvious that the seal has been broken, so that fraud is easily detected.

  In the assembly of the pachinko machine 10, for example, electrical components such as a relay board, LED board, switch, and wiring are attached to the ball assembly plate 460, and a spacer (intermediate member) 501 is attached to the ball assembly plate 460. The unit is configured as a unit, and this unit is attached to the game board 30 and then the first control board unit 201 is attached, so that workability is improved. In such a case, at least a part of the electrical components is a spacer. By covering with the (intermediate member) 501, the electrical component is protected by the spacer (intermediate member) 501, and the electrical component is prevented from being damaged during the mounting operation.

The characteristic part of this gaming machine will be described in detail with reference to FIGS. 4, 5, and 13 to 22. The basic structure which is characteristic of this gaming machine is that the launch rail 170 is provided in the vicinity of the surface of the base plate 171 of the game ball launcher 38, and the launch rail from the upper position opposite to the base plate 171. A game ball is supplied onto 170, and the game ball is launched toward the game area by the game ball launcher 38.

  As shown in FIG. 14, the firing rail 170 is formed to have an M-shaped cross section (a cross section in a direction perpendicular to the direction in which the game balls are fired), and the resin base 172 is disposed inside the M-shape. In that state, it is fixed to the base plate 171 behind it using two screws 174. The firing rail 170 is attached so as to extend linearly at a predetermined firing angle (launch angle, here 20 degrees). Accordingly, the game ball launched by the turning operation of the game ball launching handle 18 (magnetic control of the launch solenoid) is first launched obliquely upward along the launch rail 170, and then the ball of the rail unit 50 as described above. Through the guide passage, the player is guided to a predetermined game area desired by the player.

  The launch rail 170 is inclined so as to incline in a direction in which a game ball is fired from the game ball launcher 38 from a standby position P2 where the game ball (SB) waits to receive a hitting operation by the game ball launcher 38. A slanted surface that is configured to receive a game ball (SB) supplied by the ball feed mechanism 173 upstream of the firing standby position P2 and supplied by the ball feed mechanism 173. A game ball (SB) moves along the inclined surface to the launch standby position P2, and a game ball (SB) launched by the game ball launcher 38 at the launch standby position P2 along the inclined surface. The inclined surface has two surfaces that support the lower half of the game ball from both sides and is open upward. And it is what is formed in a groove shape.

  Game balls are supplied to the ball feeding mechanism 173 one by one from the ball outlet on the front frame 14 side (ball outlet leading from the most downstream part of the upper plate 19), and FIG. 14 (disassembled perspective view) and FIG. 15 (vertical side view). ), FIG. 16 (partially cutaway perspective view) and FIG. 17 (partially cutaway perspective view), the gate lever 173A provided on the ball feed mechanism 173 is connected to the solenoid 173C (main body 173D).

The gate lever 173A is rotated in the vertical direction by the excitation of the solenoid 173C, thereby opening the internal passage and dropping the game ball onto the firing rail 170. It is configured as follows.
The main body portion 173D is made of synthetic resin, has two vertical axis rotation shafts, is fitted to the bearings 171A and 171A of the rear base plate 171 and is pivotally supported. In addition, it has one locking hook 173E and is configured to be fitted into the engagement hole 171B of the rear base plate 171 using the elastic deformation of the synthetic resin.
In addition, the ball feeding mechanism 173 is disposed so as to be displaced from the firing rail 170 to the front side of the gaming machine so as not to interfere with the firing rail 170. Therefore, the game ball supplied from here is The fire rail 170 is dropped and supplied from obliquely above.

Then, as shown in FIG. 22, among the firing rails 170, the base plate 171 and the back-to-back firing standby position P2 are positioned on the base plate 171 as shown in FIGS. A first shock absorbing member 175 shown is disposed. The position P1 for receiving the supplied game ball here refers to the position supplied from the ball feed mechanism 173 and first dropped on the launch rail 170 and supplied, and the launch standby position P2 is The position where the launch is performed.
The first impact absorbing member 175 is a cushioning material that reduces the impact, and is made of a material having low resilience that absorbs the impact force. Here, a vibration damping rubber is used. As the physical properties of this material, the resilience is less than 10%. However, other than this material, rubber, synthetic resin, etc. having sufficient buffering properties can be appropriately selected and used.

As shown in FIG. 14, the base plate 171 is provided with a main opening 176, and the first shock absorbing member 175 is fitted into the main opening 176, and the base plate 171. It is comprised from the attachment site | part 175B for attaching to, and it attaches to the back surface of the said base board 171 by this attachment site | part 175B. The shock absorbing portion 175A of the first shock absorbing member 175 is located at a portion of the base plate 171 corresponding to the M-shaped top of the firing rail 170.
The first shock absorbing member 175 is attached by the following two means.

  One is that the base plate 171 is provided with two fixing openings 177 and 177 apart from the main opening 176, and the fixing part 175 </ b> B of the first shock absorbing member 175 is used for the fixing. Protrusions 178 and 178 that are fitted into the openings 177 and 177 are provided. As a result, the first shock absorbing member 175 is applied from the back surface of the base plate 171, and the projections 178, 178 are pushed into the fastening openings 177, 177 using the elastic deformation of the material. The position can be fixed by fitting.

  As shown in FIGS. 14, 18 to 21, another fitting means is provided with two mounting holes 179 and 179 in the mounting portion 175 </ b> B of the first shock absorbing member 175, and the base plate 171. Are provided with engaging projections 180 and 180 which are fitted into the mounting holes 179 and 179. The mounting holes 179 and 179 are used for the engaging projections 180 and 180 by utilizing elastic deformation of the material. It can be pushed in and fixed in position.

  In addition, the main opening 176 has the upper end 176A of the firing rail 170 having a large width in the vertical direction, and the lower end 176B formed with a smaller width than the first opening 176A. The shock absorbing portion 175A of the shock absorbing member 175 is configured in the same shape as the main opening 176.

Further, the lower portion of the lower end portion 170A of the firing rail 170 is opened so as to allow a game ball to fall, and a ball waiting member 181 is disposed above the lower end portion 170A with a predetermined height H (here, A horizontal distance L (here, the initial position P0 of the tip of the hitting portion 38A of the game ball launcher 38 and the lower end 170A of the launch rail) is provided with a distance of 7 mm from the top of the M-shaped launch rail 170. 9 mm), the horizontal distance L is set to be longer. However, even if the height H and the horizontal distance L are the same length, the purpose of defending against illegal balls can be achieved.
Further, the ball waiting member 181 is made of synthetic resin and has a substantially trapezoidal shape when viewed from the front, and is fastened to the rear base plate 171 by screws. The receiving surface side of the game ball is formed in a slanting inclined surface so that the upper side is positioned forward and the lower side is positioned rearward.

(Function)
With the above configuration, when a game ball is supplied to the launch rail 170, if the game ball is dropped and supplied from an upper position opposite to the base plate 171 of the game ball launch device 38, The game ball collides with the launching rail 170 and momentarily collides with the base plate 171 on the opposite side, but by disposing the first shock absorbing member 175 at this position, the collision energy is absorbed, It is possible to avoid the game ball from dancing on the launch rail 170 and immediately settle down to the launch standby position P2 in a stable state. Thereby, the ball sitting of the game ball can be improved, the game ball launching device 38 can always be launched in a stable posture, the game ball trajectory is stabilized, and the game ball is launched at the position intended by the player. And foul spheres are reduced. At the same time, when the game ball (normal steel ball) collides with the base plate 171 (normal aluminum alloy), the base plate 171 is scraped, dust is generated and collected on the firing rail 170, and the firing state may deteriorate. However, these problems will be solved.
Of course, the situation where the dance of the game ball is further promoted by cutting the base plate can be avoided.

  In addition, the first shock absorbing member 175 includes a shock absorbing portion 175A and a mounting portion 175B, and the whole is larger than the shock absorbing portion 175B, and is attached by the mounting portion 175B from the back surface of the base plate 171. As a result, the attachment portion 175B functions like a ridge and is difficult to peel off.

Further, the base plate 171 is provided with at least one fastening opening 177, and the attachment portion 175B is provided with a projection 178 fitted into the fastening opening 177, thereby this first shock absorption. The member 175 can be fixed to the base plate 171 by the fitting means, and can be easily attached and detached without using a screw or the like.
Of course, if there are two or more openings 177 for fastening and a plurality of the projections 178 as in the embodiment, a more firm and stable attachment can be achieved.

In addition, at least one mounting hole 179 is provided in the mounting portion 175B, and as shown in FIG. 18, the base plate 171 is provided with an engaging projection 180 to be fitted to the first impact hole. The absorbing member 175 can be fixed to the base plate 171 by the fitting means, and can be easily attached and detached without using a screw or the like.
Of course, if the number of mounting holes 179 is two or more as in this embodiment, and a plurality of the engaging projections 180 are combined, a more robust and stable mounting can be achieved.
Furthermore, when the base plate 171 includes at least one fastening opening 177 and a fitting means by a projection 178 fitted into the fastening opening 177, a more firm attachment can be performed. is there.

 Further, as shown in FIG. 22, the horizontal distance L and the height H between the initial position P0 of the tip of the hitting portion 38A of the game ball launching device 38 and the lower end 170A of the firing rail 170 are the same length. Alternatively, since the horizontal distance L is set to be longer, when a game ball SB having a smaller diameter than a game ball of a predetermined size is illegally used for the purpose of increasing the winning rate, the game ball Is supplied to the shooting rail 170, it is not received by the ball waiting member 181 and passes through the lower end portion 170A of the shooting rail 170. As a result, the game ball of the game ball shooting device 38 is passed. The ball is sandwiched between the hitting ball portion 38A and the lower end portion 170A of the firing rail 170 or falls downward from the lower end portion 170A of the firing rail 170. As a result, an illegal small-diameter game ball is not normally launched, and an illegal game using such a small-diameter game ball can be avoided in advance.

  Further, the shape of the shock absorbing portion 175A of the first shock absorbing member 175 is such that the upper end side 170B of the firing rail 170 has a large width in the vertical direction and the lower end side 170A has a smaller width. As a result, at the position where the game ball is dropped and supplied from obliquely above, the fall energy is large and the dancing by jumping is large, so it is necessary to cover this sufficiently, not a simple rectangle or circle The dance of the game ball can be further suppressed by using the above-mentioned sufficiently large shape.

  Further, when the launch rail 170 is formed so that the cross section in the direction orthogonal to the launch direction of the game ball has an M shape as in this embodiment, the game ball supplied onto the launch rail 170 from above. Will collide with the M-shaped inner slope, so that it will climb over the slope and collide with the side wall of the base plate 171 beyond the M-shaped top 170C. Since the shock absorbing portion 175A of the first shock absorbing member 175 is provided on the side wall portion of the base plate 171 exceeding the above, the ball seating action is more effective for the launch rail 170 having such a shape. Become.

(Modification)
The impact absorbing member may be further provided with a second impact absorbing member.
That is, a ball feeding mechanism 173 for supplying game balls to the firing rail 170 is provided above the side of the firing rail, but at a position facing the first shock absorbing member 175 of the ball feeding mechanism 173. A second shock absorbing member can be provided.
Specifically, the gate lever 173A is positioned at a position facing the first shock absorbing member 175, but the lower end portion of the gate lever 173A is made of a buffer material or provided with a buffer material there. To do.
As described above, the second shock absorbing member is provided at the position facing the first shock absorbing member 175 of the ball feeding mechanism 173, so that the first shock absorbing member is supplied onto the firing rail 170. When a game ball that has collided with the member 175 cannot sufficiently absorb the impact force, the game ball will be bounced to the opposite side. However, the trevor 173A of the ball feeding mechanism 173 on the opposite side (even in other parts) (B), the collision energy can be absorbed again, and the game ball can be settled at the launch standby position stably and quickly. Thereby, the ball sitting of the game ball can be further improved.
