In the gaming machine according to the present invention,
A launch rail is provided near the surface of the base plate of the game ball launching device, and a game ball is supplied onto the launch rail from an upper position on the side opposite to the base plate, and the game ball is played by the game ball launching device. A gaming machine configured to launch toward a gaming area,
Of the firing rail, a first shock absorbing member was arranged on the base plate, from a position where the supplied game ball was received to a rear firing standby position,
It is characterized by the following.
With this configuration, when a game ball is supplied to the launch rail, the game ball is launched when the game ball falls obliquely from an upper position opposite to the base plate of the game ball launching device and is supplied. Although it collides with the rail and collides too much with the base plate on the opposite side, by arranging the first shock absorbing member at this position, the collision energy is absorbed, and the game ball is placed on the launch rail. It is possible to avoid dancing and immediately settle down to the firing standby position in a stable state. Thereby, the ball sitting of the game ball can be improved, the launch by the game ball launching device can be always performed in a stable posture, the trajectory of the game ball is stabilized, and the game ball can be launched at a position intended by the player. As a result, foul spheres are reduced.
Until now, when a game ball (usually a steel ball) collides with a base plate (usually an aluminum alloy), the base plate is shaved, dust is generated and accumulated on the launch rail, and the launch condition deteriorates. However, these problems have been resolved.
Of course, by shaving the base plate, it is possible to prevent a situation in which the dancing of the game ball is further promoted.
In the present invention, the game area refers to, for example, an area surrounded by an outer rail and an inner rail.
Further, the position of the launching rail for receiving the supplied game ball means, for example, a point where the game ball is supplied onto the launching rail from an upper position on the opposite side of the base plate of the game ball launching device.
The firing standby position refers to, for example, a position where the game ball is stopped just before the firing action (hitting). Specifically, it indicates the position where the game ball is stopped and held by the lower end of the firing rail and the ball waiting member above it.
Further, the shock absorbing member is a cushioning material that reduces the impact, and whether or not to reduce the impact may be specified by, for example, a material. The cushioning 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, and a material similar thereto. In addition, a soft material as compared with the base plate may be used as the cushioning material.

In the gaming machine according to the present invention,
A ball feeding mechanism for feeding a predetermined number of game balls, a game ball launching device for launching game balls toward a game area, and the 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 for receiving a game ball supplied by the ball feed mechanism on the inclined surface having an inclined surface which is inclined upward in a direction in which the game ball is launched by the launch device, and the inclined surface being upstream of the launch standby position; A game ball supplied by the ball feed mechanism moves to the firing standby position along the inclined surface, and a game ball launched by the game ball launching device at the firing standby position moves along the inclined surface. The inclined surface has two surfaces that respectively support the lower half of the game ball from both sides and is open toward the upper side. A game machine is formed,
A base plate to which the firing rail is attached so that the surface is along the side of the firing rail, from a position for receiving a game ball supplied by the ball feed mechanism from the position on the firing rail to the firing standby position. A first shock absorbing member for reducing a shock when a game ball comes into contact is arranged at a predetermined position on the surface along the gap.
With this configuration, when the inclined surface of the firing rail is configured to support the lower half of the game ball, the resistance when the game ball is fired by the game ball firing device can be reduced and stable firing can be achieved. This can make the game easier, but there is a possibility that the rampage of the game balls supplied on the firing rail is prolonged. With the configuration of the present invention, when a game ball hit on the firing rail comes into contact with the shock absorbing member, the impact can be mitigated, and the game ball can be reduced in runaway to achieve stable firing. Will be able to

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 up-down direction and the lower end side has a smaller width than the upper end side. At a position where it is dropped and supplied obliquely from above, the falling energy is large and the dancing due to jumping is large, so it is necessary to cover this sufficiently. With the irregular shape, the dance of the game ball can be further suppressed.

Means 9: In the gaming machine of means 3 to means 8,
The launch rail is formed such that a cross section in a direction perpendicular to the launch direction of the game ball has an M shape, and a shock absorbing portion of the first shock absorbing member has a base plate corresponding to a top of the M shape. It is characterized by being located in a part.
In this manner, when the firing rail is formed such that a cross section in a direction orthogonal to the firing direction of the game ball has an M shape, the game ball supplied from above to the firing rail is inside the M shape. Since it collides with the slope, it climbs up the slope, crosses the M-shaped top, and collides with the side wall of the base plate. By providing the shock absorbing portion of the first shock absorbing member, the ball seating action becomes more effective for the firing rail having such a shape.

  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 convenience, but the present invention uses a ball game machine other than a pachinko machine (such as an arrange ball machine or a sparrow ball game machine) and other game balls. The 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 of 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. FIG. 4 is a perspective view showing a state where the front frame 14 is opened, FIG. 5 is a front view showing a state where the front frame 14 is opened, and FIG. 6 is a front view showing the game board 30.

As shown in FIGS. 1 to 6, the pachinko machine 10 includes an outer frame 11 forming an outer shell of the pachinko machine 10 and an inner frame 12 supported on one side of the outer frame 11 so as to be openable and closable. 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 a 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 up and down on the opposite side (left side of the pachinko machine 10 in FIG. 1) from the front of the pachinko machine 10 opposite to the location where the game ball firing handle 18 is installed. The inner frame 12 can be sufficiently opened to the front side with respect to the axis. The inner frame 12 is made of a synthetic resin, specifically, an ABS (acrylonitrile-butadiene-styrene) resin. By doing so, the advantages of high viscosity, high impact resistance, and low-cost production can be obtained.

  The lower plate unit 13 is fixed to the inner frame 12 by fasteners such as screws. On the front side of the lower plate unit 13, a lower plate 15, a ball pulling lever 17, a game ball firing handle 18, an ashtray 22, and a sound output port 24 (upper left and right upper end positions of the inner frame 12) are provided. The lower plate 15 as a ball tray is provided substantially at the center of the lower plate unit 13 and serves to stop game balls discharged from the discharge port 16 when the upper plate 19 described later becomes full. There is. The ball removing lever 17 is for removing game balls in the lower plate 15. By moving the ball removing lever 17 to the left in FIG. 1, a predetermined portion of the bottom surface of the lower plate 15 is opened, The game balls retained in the plate 15 can be discharged to the player's ball storage box (dollar box) through the opening on the bottom surface of the lower plate 15.

The game ball firing handle 18 is disposed so as to protrude rightward from the lower plate 15 to the near side. In response to the operation of the game ball firing handle 18 by the player, the game balls are driven toward the game board 30 by the game ball firing device 38 (see FIG. 4). The game ball launching device 38 includes the game ball launching handle 18, a set handle described later, a launching motor, and the like.
The sound output port 24 is an output port for outputting a sound from a speaker provided at the upper right and left ends of the inner frame 12. The ashtray 22 is provided to the left of the lower tray 15, as shown in FIG. The ashtray 22 is supported so as to rotate (for example, rotate forward toward the front side) around an axis in the left-right direction (horizontal direction).

  It should be noted that the lower plate unit 13 is mostly formed of ABS resin, like the inner frame 12. By doing so, it is possible to have high viscosity and be strong against impact, and to manufacture at low cost. Particularly, the surface layer forming the lower plate 15 and the front panel portion at the back of the lower plate 15 are formed of flame-retardant ABS resin. For this reason, this part is difficult 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 opening / closing axis extending vertically to the left as viewed from the front of the pachinko machine 10. It can be opened to the front with your heart in mind. Moreover, the front frame 14 is attached so as to fit into the outer wall (rib) 12b 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) 12 b of the inner frame 12, the foreign matter (needle-shaped) is inserted through the gap between the inner frame 12 and the front frame 14. Alternatively, it is a thin plate or the like, which can prevent illegal acts such as inserting a wire, a piano wire, a celluloid plate or the like. Further, the front frame 14 is made of a synthetic resin, specifically, an ABS resin, like the inner frame 12, so that the front frame 14 has high viscosity, can be 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 below the front frame 14 (at a position above the lower plate 15 described above). The upper plate 19 is a ball tray for temporarily storing game balls and guiding them toward the game ball launching device 38 while aligning them in a line. Like the lower plate 15, the upper plate 19 has a configuration in which the surface layer is formed of a flame-retardant ABS resin.

As shown in FIG. 4, the inner frame 12 is mainly composed of a resin base 20 having a rectangular outer shape, and a substantially circular window hole 21 is formed in the center of the resin base 20.
On the rear side of the resin base 20, a game board 30 shown in FIGS. 4 to 6 is detachably mounted. As shown in FIG. 6, the game board 30 is made of a square plywood, one upper corner of which is cut off (described later), and the peripheral edge thereof abuts against the back side of the resin base 20 (the inner frame 12). Installed in state.

  Accordingly, a substantially central portion of the front surface of the game board 30 is exposed to the front side of the inner frame 12 through the window hole 21 of the resin base 20 (an out port 36 of the game board 30 is shown in FIG. 4). ing). Here, here, a corner (corner) close to a pivot portion of the inner frame 12 of the gaming board 30 with respect to the outer frame 11 (a pivot centered on an opening / closing axis extending vertically to the left as viewed from the front of the pachinko machine 10). However, as shown in FIG. 6, a corner is dropped (notched) 720 into a substantially triangular shape (the notch is a circular arc line but is 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. At a position slightly below the left and right of the game board 30, a pair of general winning ports 31, 31 are arranged in a stepwise manner, and a starting port 33 is arranged below the center. The general prize ports 31, 31 and the start port 33 are openings penetrating from the game area toward the back surface, and prize devices are attached to the openings. That is, the corresponding incoming ball detection sensors are provided on the back of the game board 30, and these sensors are connected to a main control board (main control device) to be described later through electric wiring (not shown). .
When a game ball enters the general winning opening 31, 31 and the starting opening 33, it is detected by each of the detection sensors, and based on the output of the detection sensor, the upper plate 19 (or the lower plate 15) is detected. When a predetermined number of prize balls are paid out and game balls enter the starting port 33, a lottery to be described later is started.

The detection results respectively detected by the winning detection sensors are taken into a main control board, which will be described later, and a payout command (payout number of game balls) according to a prize situation is issued 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 (a so-called evidential ball method) in which game balls that have won various winning ports are once collected in a winning ball processing device, and the payout balls are checked out one by one by the winning ball processing device and paid out one by one. Unlike the pachinko machine 10 of the present embodiment, the payout is immediately performed by electrically detecting the winning of the game ball for each of the various winning ports (that is, the pachinko machine 10 of the present embodiment eliminates the winning ball processing device). are doing). Therefore, even if there are a large number of game balls to be paid out, the payout can be promptly carried out. However, the conventional “evidence sphere method” may be applied to the present invention.

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

  The game board 30 is provided with a rail unit 50 for guiding the game balls fired from the game ball launching device 38 to the upper part of the game board 30, and is fired by the turning operation of the game ball firing handle 18. The played game ball is 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, molded by adding a fluorine resin), and has an inner rail 51 and an outer rail 52 which are integrally formed inside and outside. .

Since the rail unit 50 is formed by adding a fluororesin, the frictional resistance of the game ball can be reduced. The inner rail 51 is formed in a substantially annular shape except for about 1/4 of the upper part, and an outer rail 52 is formed so as to face a part (mainly the left side) or the inner rail 51.
In such a case, a guide rail is formed by the inner rail 51 and the outer rail 52, and a ball guide passage is formed by a portion (the left side as viewed) 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 an abutment surface with the game board 30, that is, a groove shape having an open front side.

  A return ball preventing member 53 is attached to a tip portion (upper left portion in FIG. 6) of the inner rail 51. This prevents a situation in which a game ball once guided from the ball guide passage between the inner rail 51 and the outer rail 52 to the upper portion of the game board 30 returns to the ball guide passage again. I have. A return rubber 54 is attached to the outer rail 52 at a position corresponding to the maximum flying portion of the game ball (upper right portion in FIG. 6: a portion corresponding to the tip of the outer rail 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is rebounded. On the inner surface of the outer rail 52, a long sliding plate as a stainless steel metal band is provided to make the flying of the game ball smoother, that is, to reduce the frictional resistance of the game ball. Is being worn.

  An arc-shaped flange 56 that protrudes outward is formed on the outer peripheral portion of the rail unit 50. The flange 56 forms a mounting surface for the game board 30. When the rail unit 50 is mounted on the game board 30, the flange 56 abuts on the game board 30, and in this state, screws and the like are inserted through a plurality of through holes formed in the flange 56, and the game board is The rail unit 50 is fastened to the rail 30.

A projection 57 is formed at the entrance of the ball guide passage between the inner rail 51 and the outer rail 52 so as to partially close the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail 51 to the lower end of the rail unit 50, and serves to guide a foul ball flowing backward in the ball guide passage without reaching the game area to the foul ball passage. .
The lower right corner and the lower left corner of the game board 30 are spaces for sticking stickers (S1, S2 in FIG. 6) such as a stamp (for example, a serial number is described) and plates. Notches 58 and 59 are formed in the flange 56 to secure this attachment space. By sticking a seal such as a stamp (S1, S2 in FIG. 8) on the lower right corner or the lower left corner of the game board 30, uniqueness between the game board 30 and the stamp can be imparted.

Next, the game area will be described. The game area is defined by an inner circumference (inner and outer rails) of the rail unit 50 in a substantially circular shape. In the present embodiment, the game area is an area excluding a guide rail area, which is a parallel part of the inner and outer rails 51 and 52, of an area surrounded by the inner rail 51 and the outer rail 52 when viewed from the front of the pachinko machine 10. And
Therefore, when the game area is referred to, the guide rail portion is not included, so that 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. The upper limit position of the game area is specified by the outer rail 52.

  In the resin base, a firing rail 170 for guiding a game ball immediately after being fired by the game ball firing device 38 is attached below the window hole 21 (game board 30). The firing rail 170 is mounted and fixed to the resin base 172 via a base plate 171 (a member for mounting the game ball firing device 38), which is a metal plate (here, an aluminum alloy) at the rear of the firing rail 170. It is configured to extend linearly at an angle (launch angle). Such a configuration will be described later in detail with reference to FIG. Therefore, the game ball fired by the turning operation of the game ball firing handle 18 is firstly launched diagonally upward along the firing rail 170, and then to a predetermined game area through the ball guide passage of the rail unit 50 as described above. You will be guided.

  There is a gap at a predetermined interval between the firing rail 170 and the rail unit 50 (guide rail), and a foul ball passage is formed below this gap. Therefore, if the game ball fired from the game ball launching device 38 does not reach the return ball preventing member 53 and returns in the guide rail as a foul ball, the foul ball is transferred to the lower plate 15 through the foul ball passage. Is discharged.

  When the foul ball flows backward in the guide rail, most of the foul ball flows along the outer rail 52 and falls downward when it reaches the lower end of the outer rail 52. However, some foul balls fall in the guide rail. In some cases, it jumps to the inner rail 51 side. At this time, the bounced foul ball hits the convex portion 57 of the ball guide passage entrance and is guided to the foul ball passage, whereby all the foul balls are reliably guided to the foul ball passage, Interference between the ball and the game ball to be fired next is suppressed.

  As will be described later in detail with reference to FIG. 13 and the like, the game ball launching device 38 has one ball from a ball outlet on the front frame 14 side (a ball outlet leading from the most downstream portion of the upper plate 19).

The payout of the prize ball and the loan ball is controlled.

  The firing control device 312 controls the firing motor in accordance with the operation of the game ball firing 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 and the like. The card unit connection board 314 is electrically connected to the ball lending operation unit 120 (see FIG. 1) on the front of the pachinko machine and a card unit (not shown), and takes in a ball lending operation command by the player and sends it to the payout control device 311. Is output to In a cash machine in which game balls are directly rented to the upper plate 19 from a ball rental device or the like without using a card unit, the card unit connection board 314 is unnecessary.

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

Here, the description relating to the above-mentioned firing control device 312 will be described in detail.
The launch control device 312 includes a launch control circuit. The firing control circuit is responsible for controlling the firing of the firing solenoid in accordance with the operation of the game ball firing handle 18 by the player, and the firing solenoid is driven when predetermined firing conditions are met. Specifically, the firing control circuit is connected with a firing switch, a touch sensor, and a hitting switch provided on the game ball firing handle 18 so that the firing switch and the touch sensor are on and the hitting switch is off. Only when this happens, a firing permission signal is output to the control board 80 of the main controller 261 (via the power supply monitoring board). The control board 80 outputs a firing control signal (pulse signal of 5 volts) of a predetermined cycle to the firing control circuit based on the input of the firing permission signal. The launch control circuit is provided with an amplifier (FET), and every time the launch control signal is input, the amplifier instantaneously supplies the power stored in the capacitor (for example, supplies 32 volt power). This drives the firing solenoid. In this case, the game ball firing handle 18 is provided with a dial variable resistor for determining the handle operation amount, and the firing control circuit is charged in the capacitor based on a change in the resistance value of the dial variable resistor. The launch speed of the firing solenoid is determined by adjusting the amount of power supply.
Also, in the control device 80, as normal processing, external output processing for outputting various commands to other control boards, updating processing of various counters, setting processing of commands, processing for opening and closing a special winning opening according to a hit state, game The ball launch control processing and the like are sequentially executed. The game ball launch control process is executed every 4 msec (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 value of the launch counter after the addition is 150 or more. In such a case, a time of 0.6 sec is required until the firing counter reaches 0 to 150. If the value of the firing counter HC is less than 150 in this step, this processing is terminated as it is, while if the value of the firing counter HC is 150 or more, the firing counter is cleared to 0. Next, it is determined whether or not the firing permission flag is set in the firing permission flag storage area of the RAM. The firing permission flag is a flag that is set when a firing permission signal is output from the firing control device 312. If the firing permission flag has been set, a firing control signal is output to the firing control device 312. If the firing permission flag has not been set, the process ends without outputting the firing control signal. In such a case, a configuration may be adopted in which the firing control signal is output on condition that the CR unit is connected without any defect. 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 present pachinko machine 10, a game ball is fired on condition that the player operates the game ball firing handle 18. In addition, as described above, a time of 0.6 sec is required until the firing counter reaches 0 to 150. Therefore, basically, the firing control signal is output 100 times per minute, and 100 times per minute. A game ball is fired. In addition, as described above, the configuration in which the control board 80 controls the permission of launching the game ball is to place a main part of the game in the pachinko machine 10 of launching the game ball 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 at the time of a payout error such as a clogged ball of the payout motor unit, the payout motor is rotated in the normal or reverse direction, so that the clogged ball is cleared (return to a normal state). Has become. The power control device 313 is provided with a RAM erase switch 323.

  As shown in FIG. 4, the corners of the game board 30 near the pivot portion 725 of the inner frame 12 with respect to the outer frame 11 have a substantially triangular shape as shown in FIG. ). As shown in FIG. 4, the pivot portion 725 is configured by pivotally attaching a mounting bracket fixed to the inner frame 12 to a bracket 726 (upper end) fixed to the outer frame 11 (the lower end is not shown).

  The spacer (intermediate member) 501 is made of a transparent resin, so that the presence or absence of a wrongdoing in the inside can be easily visually recognized from the outside, so that fraud can be more effectively prevented. Has become. Of course, the material may be formed of a translucent or opaque material instead of a transparent resin.

  A pair of upper and lower shafts 462 is provided at the end (the right end in FIG. 12) of the ball assembly plate 460 opposite to the end on which the opening / closing mechanism 410 is formed so as to project upward. The bracket 513 of the spacer (intermediate member) 501 is inserted through the shaft 462, thereby forming a spacer opening / closing means 466. Thus, the spacer (intermediate member) 501 has one end centered on the shaft 462 at one end. And is rotatably supported on a horizontal plane and can be opened and closed. That is, the opening / closing axis of the spacer (intermediate member) 501 is set so as to extend vertically on the opposite side (the right side in FIG. 12) of the opening / closing mechanism 410 forming end when viewed from the back of the pachinko machine 10. The spacer (intermediate member) 501 can be sufficiently opened rearward with the axis as the axis.

  As shown in FIG. 10, the first substrate case 201A is rotated by the opening / closing mechanism 410 at the end on the side where the opening / closing mechanism 410 is formed (the left end in FIG. 10) to one side (to the left in FIG. 10). Although it can be opened, the spacer (intermediate member) 501 has a structure opposite to that of the first substrate case 201A as shown in FIG. It can be opened in any direction. That is, the spacer (intermediate member) 501 and the first substrate case 201A can be opened and closed in the left and right opposite directions, more specifically, can be closed by folding from the left and right, and from the closed state. Each has a structure that can be opened to the left and right.

  The spacer (intermediate member) 501 and the sphere collecting plate 460 are provided at the free end side (the left end side in FIGS. 10 and 12) of the spacer (intermediate member) 501 and the corresponding position on the sphere collecting plate 460. And sealing means for sealing. This sealing means has a first sealing portion 520a and a second sealing portion 520b.

  The upper and lower breaking screw insertion portions 515 provided at the bottom of the recessed portion of the spacer (intermediate member) 501 are provided between the upper and lower support portions of the bracket 413 in the opening / closing mechanism 410 as shown in FIGS. The first substrate case 201A is formed near the rivet head, which is a shaft 411 pivotally connecting the first substrate case 201A.

  As shown in FIGS. 10 to 12, a fixed end (right end in FIGS. 10 and 12) on the outer surface (side surface of the first substrate case 201A) of the spacer (intermediate member) 501 is locked to the tip. A rectangular locking piece 517 on which a claw is formed is disposed so as to protrude rearward (to the first substrate case 201A side), while a rectangular projection is provided on a free end of the first substrate case 201A. The portion 851 is disposed so as to protrude to the side (to the left in FIG. 10), and the locking piece 517 can be elastically locked to the projection 851. The locking piece 517 is integrally formed with the 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, since the spacer (intermediate member) 501 is interposed between the back surface of the game board 30 and the first control board unit 201, the space between the back face of the game board 30 and the first control board unit 201 is increased. The gaps between them are filled, so that no space is created for possible cheating. Further, since the spacer (intermediate member) 501 is fixed in a sealed state by the sealing means 520, it is difficult to remove the spacer illegally, and even if this sealing is broken illegally. Since traces remain, it is obvious at a glance that the seal has been broken, whereby fraudulent acts can be easily found.

  In assembling the pachinko machine 10, for example, electric components such as a relay board, an LED board, a 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, and these components are attached. If 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, the workability is improved. In such a case, at least a part of the electric component becomes a spacer. By covering with the (intermediate member) 501, the electric component is protected by the spacer (intermediate member) 501, and the electric component is prevented from being damaged during the mounting operation.

(Feature configuration)
Characteristic portions of this gaming machine will be described in detail with reference to FIGS. 4, 5, 13 to 22. The basic configuration of this gaming machine is that the launch rail 170 is provided in close proximity to the surface of the base plate 171 of the game ball launching device 38, and the launch rail 170 is provided from an upper position opposite to the base plate 171. A game ball is supplied on the game 170 and the game ball is launched by the game ball launching device 38 toward a game area.

  As shown in FIG. 14, the firing rail 170 is formed so as to have an M-shaped cross section (a cross section in a direction orthogonal to the firing direction of the game ball), and the resin base 172 is provided inside the M shape. In this 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 (a launch angle, here, 20 degrees). Therefore, the game ball fired by the turning operation of the game ball firing handle 18 (the magnetic force control of the firing solenoid) is first struck diagonally upward along the firing 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 from the launch standby position P2 where the game ball (SB) waits to receive the hitting operation of the game ball launching device 38 in a direction in which the game ball is launched from the game ball launching device 38. The game device is configured to receive a game ball (SB) supplied by the ball feeding mechanism 173 at a position upstream of the firing standby position P2 on the inclined surface and provided by the ball feeding mechanism 173. The game ball (SB) moves to the launch standby position P2 along the inclined surface, and the game ball (SB) launched by the game ball launching device 38 at the launch standby position P2 moves along the inclined surface. The inclined surface has two surfaces that respectively 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 one by one to the ball feed mechanism 173 from the ball outlet on the front frame 14 side (ball outlet leading from the most downstream portion of the upper plate 19), and FIG. 14 (exploded perspective view), FIG. ), FIG. 16 (a partially cutaway exploded perspective view), and FIG. 17 (a partially cutaway perspective view), a gate lever 173A provided in the ball feed mechanism 173 is provided with a solenoid 173C (in the body 173D). The game balls are supplied one by one onto the launch rail of the game ball launching device 38 (indicated by arrows in the figure). The game ball launching device 38 is provided with a rhinoceros cone-shaped hitting portion 38A made of a synthetic resin, and is fixed to the tip of the shaft portion 38B. A ball is fired.

As shown in FIGS. 14 to 17, the ball feed mechanism 173 includes a main body 173D having a passage for a game ball, a solenoid 173C, and a gate lever 173A pivotally supported by the ball feed mechanism 173 on the horizontal axis. When the solenoid 173C is excited, the gate lever 173A is turned up and down, thereby opening the internal passage and dropping and discharging the game ball onto the firing rail 170. It is configured as follows.
The main body 173D is made of synthetic resin, has two rotating shafts having a vertical axis, and is fitted to bearings 171A and 171A of a rear base plate 171 to be rotatably supported. It has one locking hook 173E, and is configured to be fitted into the engaging hole 171B of the rear base plate 171 by using the elastic deformation of the synthetic resin.
Further, the ball feed mechanism 173 is disposed so as to be displaced on the front side of the gaming machine with respect to the firing rail 170 so as not to hinder the firing rail 170. It is dropped and supplied to the firing rail 170 from obliquely above.

Then, as shown in FIG. 22, of the firing rail 170, the base plate 171 extends from a position P1 for receiving the supplied game ball to a rearward firing standby position P2, as shown in FIGS. The illustrated first shock absorbing member 175 is arranged. Here, the position P1 for receiving the supplied game ball refers to a position supplied from the ball feed mechanism 173 and first dropped and supplied on the firing rail 170, and the firing standby position P2 is The position where the launch of the launch is performed.
The first shock absorbing member 175 is a cushioning material for absorbing shock and is made of a material having low rebound resilience for absorbing shock force. Here, a damping rubber is used. The material has a rebound resilience of less than 10%. However, other than this material, a rubber, a synthetic resin, or the like having a sufficient cushioning property can be appropriately selected and used.

Then, as shown in FIG. 14, a main opening 176 is provided in the base plate 171, and a shock absorbing portion 175 A in which the first shock absorbing member 175 is fitted into the main opening 176, and the base plate 171. And a mounting portion 175B for mounting to the rear surface of the base plate 171 by the mounting portion 175B. The shock absorbing portion 175A of the first shock absorbing member 175 is located on 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 fastening openings 177, 177 apart from the main opening 176, and the fastening portion 175B of the first shock absorbing member 175 is provided with the fastening holes 177B. Protrusions 178, 178 fitted into the openings 177, 177 are provided. Thus, 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 fixing openings 177, 177 by utilizing the elastic deformation of the material. By fitting, the position can be fixed.

  Another fitting means is provided with two mounting holes 179, 179 at a mounting portion 175B of the first shock absorbing member 175, as shown in FIGS. Are provided with engaging projections 180, 180 fitted into the mounting holes 179, 179, and the mounting holes 179, 179 are formed in the engaging projections 180, 180 by utilizing elastic deformation of the material. It can be pushed in and fixed in position.

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

A lower portion of the lower end 170B of the firing rail 170 is opened to allow a game ball to fall, and a ball waiting member 181 has a predetermined height H (here, above the lower end 170B). A horizontal distance L (here, between the initial position P0 of the tip of the hitting portion 38A of the game ball firing device 38 and the lower end 170B of the firing rail is provided at a distance of 7 mm from the top of the M-shaped firing 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 protecting against illegal balls can be achieved.
Further, the ball waiting member 181 is made of a synthetic resin and has a substantially trapezoidal shape when viewed from the front, and is fixed to the rear base plate 171 by screws. The receiving surface side of the game ball is formed on an obliquely inclined surface such that the upper side is located forward and the lower side is located backward.

(Action)
With the above-described configuration, when a game ball is supplied to the firing rail 170, when the game ball falls and is supplied obliquely from an upper position on the side opposite to the base plate 171 of the game ball launching device 38, The game ball collides with the firing rail 170 and collides with the base plate 171 on the opposite side with excessive force. However, by disposing the first shock absorbing member 175 at this position, the collision energy is absorbed, It is possible to prevent the game ball from dancing on the firing rail 170 and immediately settle down to the firing standby position P2 in a stable state. Thereby, the ball sitting of the game ball can be improved, the launch by the game ball launching device 38 can be always performed in a stable posture, the trajectory of the game ball is stabilized, and the game ball is launched at a position intended by the player. And the foul sphere is reduced. At the same time, when the game ball (usually a steel ball) collides with the base plate 171 (usually an aluminum alloy), the base plate 171 is shaved, and dust is generated and accumulates on the firing rail 170, so that the firing state deteriorates. However, these problems will be resolved.
Of course, by shaving the base plate, it is possible to prevent a situation in which the dancing of the game ball is further promoted.

  Further, the first shock absorbing member 175 is composed of a shock absorbing portion 175A and a mounting portion 175B. The first shock absorbing member 175 is larger than the shock absorbing portion 175B, and is attached from the back surface of the base plate 171 by the mounting portion 175B. As a result, the attachment portion 175B functions as a flange, making it difficult to peel off.

Further, the base plate 171 is provided with at least one fastening opening 177, and the mounting portion 175B is provided with a projection 178 fitted into the fastening opening 177, so that the first shock absorbing portion is provided. The member 175 can be fixed to the base plate 171 by a fitting means, and can be easily attached and detached without using screws or the like.
Of course, if the number of the fixing openings 177 is two or more as in the embodiment and the number of the projections 178 is plural, the mounting can be performed more firmly and stably.

Also, at least one mounting hole 179 is provided in the mounting portion 175B, and as shown in FIG. 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 screws or the like.
Of course, if the number of the mounting holes 179 is two or more as in this embodiment, and if the number of the engaging projections 180 is plural, the mounting can be performed more firmly and stably.
Furthermore, when the base plate 171 is used together with 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.

  As shown in FIG. 22, the horizontal distance L between the initial position P0 of the tip of the hitting portion 38A of the game ball firing device 38 and the lower end 170B of the firing rail 170 and the height H 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 launch rail 170, the ball is not received by the ball waiting member 181 and passes therethrough, and passes over the lower end 170B of the launch rail 170. As a result, the game ball is placed on the game ball launch device 38. It will be pinched between the hitting portion 38A and the lower end 170A of the firing rail 170, or will fall downward from the lower end 170B of the firing rail 170. As a result, an illegal small-diameter game ball is not fired properly, and an illegal game using such a small-diameter game ball can be avoided.

  Further, the shape of the shock absorbing portion 175A of the first shock absorbing member 175 is such that the upper end side of the firing rail 170 has a large width in the vertical direction and the lower end side has a smaller width than that. At the position where the game ball is dropped and supplied from diagonally above, the falling energy is large and the dancing by jumping is large, so it is necessary to cover this sufficiently. With the irregular size, the dance of the game ball can be further suppressed.

  Also, in the case where the firing rail 170 is formed such that a cross section in a direction perpendicular to the firing direction of the game ball has an M shape as in this embodiment, a game ball supplied onto the firing rail 170 from above. Will collide with the inner slope of the M-shape, and will climb up the slope to exceed the M-shaped top 170C and collide with the side wall of the base plate 171. 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 height, the ball seating action on the firing rail 170 having such a shape is more effective. Become.

(Modification)
The above-mentioned shock absorbing member may be further provided with a second shock absorbing member.
That is, a ball feed mechanism 173 for supplying a game ball to the firing rail 170 is provided above a side portion of the firing rail, but at a position opposed to the first shock absorbing member 175 of the ball feed mechanism 173. , A second shock absorbing member can be provided.
Specifically, the gate lever 173A is located at a position facing the first shock absorbing member 175, and the lower end portion itself may be made of a cushioning material or provided with a cushioning material there. I do.
As described above, by providing the second shock absorbing member at a position of the ball feed mechanism 173 opposed to the first shock absorbing member 175, the second shock absorbing member is supplied onto the firing rail 170 and the first shock absorbing member is supplied. When the game ball colliding with the member 175 cannot sufficiently absorb the impact force, the ball is flipped to the opposite side. However, the gate lever 173A of the ball feed mechanism 173 on the opposite side (other parts) Provided that the second impact absorbing member is provided, the collision energy can be absorbed again, and the game ball can be quickly and stably settled at the firing standby position. Thereby, the ball sitting of the game ball can be further improved.

  INDUSTRIAL APPLICABILITY The present invention can be appropriately applied to various types of game machines provided that they have a game ball launching device and a launch rail, and the applicable range is wide.
