Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a hitting ball launching device for a pachinko machine, in which a plunger portion of a solenoid is provided with a resilient portion, and the resilient portion faces a firing rail firing position. It is about.

<Prior Art> A conventional solenoid type launcher is disclosed in, for example, Japanese Patent Laid-Open No. 61-2937.
As described in Japanese Unexamined Patent Publication No. 5 (1999), a solenoid is placed on a cushion mount such as rubber or mounted, or disclosed in JP-A-58-16.
As described in Japanese Patent No. 5876, the solenoid is directly fixed without using a buffer mount.

<Problems to be Solved by the Invention> When the solenoid is directly fixed, vibrations when the plunger moves back and forth and shocks when a ball is shot are transmitted to the launching handle, which gives the player discomfort. Further, when the solenoid is attached via the cushion mount, the shock can be absorbed by the cushion mount by reducing the spring constant of the cushion mount, so that the vibration and the shock transmitted to the firing operation handle can be reduced. However, in this case, since the cushion mount is soft, the entire solenoid swings a lot each time the plunger moves back and forth, and when the projectile part repels the ball, it hits a position deviated from the center of the ball, The desired unevenness flying phenomenon that the firing direction of the hitting ball varies and the flight distance of the hitting ball is not stable. Further, if the spring constant of the buffer mount is increased to harden the buffer mount itself in order to prevent the uneven flying phenomenon, the vibration of the solenoid is transmitted through the buffer mount, and the buffer function is not exerted.

<Means for Solving Problems> The present invention has been proposed in view of the above, and a guide pin is fixed to a front surface of a reference plate provided with a firing rail substantially parallel to a firing direction of a hit ball, and the guide pin is fixed. Insert the solenoid into the mounting hole that is movably installed along the guide pin by inserting the solenoid into the guide hole, and let the elastic part provided at the tip of the plunger of the solenoid face the firing position of the firing rail. A cushioning member made of an elastic material is brought into contact with.

<Action> Even if the solenoid tries to vibrate when firing a hit ball, the mount moves back and forth slightly along the guide pin, and does not affect the positional relationship between the ball and the ball. . Further, even if the solenoid moves back and forth together with the mount, the cushioning member absorbs this vibration.

<Examples> The present invention will be described below based on Examples of the drawings.

The pachinko machine 1 has a frame-shaped front frame 2 as shown in FIG.
The reference plate 3 is erected below the back side of the game machine, and the game board 4 is provided so as to be placed on the reference plate 3.
A firing rail 5 is obliquely provided on the front surface of the reference plate 3, and an upper guide portion 6 is provided above the launch rail 5 at an interval allowing a hit ball to pass therethrough, and a firing formed at the lower inclined end of the launch rail 5. A launching device 8 is provided so as to face the position 7, and a ball supply device 9 is provided near the launching device 8.

The launching device 8 includes a plunger type solenoid 12 in which a plunger 10 is provided with a resilient part 11 made of urethane rubber or the like.
And a mounting base 13 for mounting the solenoid 12 and the mounting base 13
A base 15 that movably supports the guide pins 14 and 14.
Etc. Plunger type solenoid 12
The cylindrical coil 16 is penetrated through the plunger 10 and the plunger 10
When the coil 16 is energized, the plunger 10 is repulsed by the return spring 10 '.
Along with it, it projects forward (left side in FIG. 2). The mounting base 13 to which the solenoid 12 is attached is a shallow frame body having an open front surface that is slightly larger than the solenoid 12, and an upper support portion 18 having a long hole 17 formed as a guide hole is projectingly provided on one side of the upper edge. At the same time, lower support portions 20 having round holes 19 as guide holes are provided at both ends of the lower edge so as to project. The long hole 17 formed in the upper support portion 18 and the round hole 19 formed in both lower support portions 20 are
The solenoid 12 is located substantially parallel to the axial direction of the plunger 10, and the round holes 19 of the lower support 20 are located on a straight line. Guide pins 14, 1 for movably supporting such a mounting base 13.
Reference numeral 4 denotes a lower guide pin 14, 1 which is arranged substantially parallel to the axial direction of the plunger 10 of the solenoid 12 and which is fitted with the lower support portion 20.
Cylindrical cushioning materials 21, 21 are fitted to the front and rear ends of 4.
The cushioning material 21 is a support piece for the lower support portion 20 of the mounting base 13 and the base 15.
It is interposed between the first and second terminals 22 and absorbs the vibration in the front-back direction of the solenoid 12, and is made of an elastic material such as polyurethane. The cushioning material 21 is not limited to the one fitted to the guide pin 14, and may be in contact with the mounting base 13 so as to regulate the movement of the mounting base 13. The base 15 is for fixing the launching device 8 to the reference plate 3, and has mounting pieces 23a and 23b projecting from the upper edge and the front end thereof, and mounting holes are formed in the mounting pieces 23a and 23b.

In order to attach the launching device 8 having the above-described configuration to the reference plate 3, the resilient part 11 of the solenoid 12 is directed to the launching position 7 of the launching rail 5, and the center line of the plunger 10 is almost aligned with the extension line of the launching rail 5. Match or launch rail 5
The screws 24 are passed through the mounting holes of the base 15 in a state in which the screws 24 are slightly inclined, and the screws 24 are screwed and fixed to the reference plate 3. Launcher 8 mounted in this way
In the normal state where the solenoid 12 is demagnetized, as shown by the solid line in FIG. 2, the plunger 10 is retracted by the urging of the return spring 10 ', and the resilient part 11 is stopped at the launch preparation position separated from the launch position 7. To do. Then, when the solenoid 12 is excited, the plunger 10 vigorously moves forward due to the magnetic force generated in the coil 16, the projecting portion 11 plunges into the firing position 7 and fires the ball at the firing position 7 (chain line in FIG. 2). When a ball is fired, vibration is transmitted to the solenoid 12 due to the impact and reaction at that time. Even if vibration is transmitted to the solenoid 12, the mounting base
Since the vertical and horizontal movements are restricted by fitting the support portions 18 and 20 of 13 and the guide pins 14 and 14, the mounting base 13 can be moved back and forth slightly along the guide pins 14 and 14. is there. Therefore, the solenoid 12 does not vibrate or swing in the vertical and horizontal directions, and the center line of the plunger 10 does not deviate from the predetermined position. For this reason, even when the elastic unit 11 moves forward by re-excitation of the solenoid 12, the elastic unit 11 always follows the same trajectory and plunges into the same position as the firing position 7. Therefore, there is no change in the positional relationship between the ball and the elastic unit 11, the ball can always be stably fired, and the uneven flying phenomenon does not occur. Also, the solenoid 12 has the guide pin 1
Even if it vibrates slightly in the front-back direction along 4, 14, this vibration is absorbed by the cushioning materials 21, 21 and is not transmitted to the reference plate 3. Therefore, unpleasant vibration is not transmitted to the firing operation handle operated by the player.

In addition, the flight distance of the hit ball launched by the launching device 8 is
The exciting force of the solenoid 12 can be adjusted by operating the firing operation handle to adjust the distance to a distance desired by the player.

In the embodiment shown in the drawing, the backward movement of the plunger 10 that fires a hit ball is used to operate the ball feeder 9 to feed one ball guided from the upper plate 25 to the firing position 7.

In the ball supply device 9, a swing rod 26 whose lower end faces the rear end of the plunger 10 is swingably attached to the front surface of the reference plate 3 by a support shaft 27, and one end is attached to the upper end of the swing rod 26. Connected transmission rod
The other end of 28 is connected to the upper portion of a claw member 29 axially mounted above the solenoid 12, and an upper claw portion 30 and a lower claw portion 31 formed on the claw member 29 are connected.
Facing the sprocket 32. A first stopper piece 33 and a second stopper piece 34 project upward in the middle of the length of the transmission rod 28, one end of a spring 35 is connected to the second stopper piece 34, and the first stopper piece 33 and A stopper protrusion 36 protruding from the reference plate 3 is exposed in the space between the second stopper pieces 34. Therefore, the transmission rod 28 always keeps the spring 35.
The first stopper piece 33 is stopped in contact with the stopper protrusion 36 by the urging force. The sprocket 32 has a plurality of grooves 37 ... Fitting one sphere to the outer peripheral edge, and a part of the outer peripheral edge faces the inside of the ball introducing trough 38 from the opening 38 'of the folded portion of the ball introducing trough 38. It is rotatably attached to the front surface of the reference plate 3 in a closed state. The ball introduction trough 38 guides the ball introduced from the upper plate 25 provided on the front panel of the pachinko machine 1 through the introduction port 39 to the launch position 7 of the launch rail 5, and the entrance 38a opening forward is the panel. An outlet 38b, which communicates with the inlet 39 and opens rearward, opens above the firing rail 5. As shown in FIGS. 7 and 8, the ball introducing trough 38 is molded separately from the reference plate 3 and the upper guide portion 6, and has a tip at the lower end of the back surface of the collar portion 40 with a hook shape. Locking claw
As for 41, upward locking portions 42, 42 are provided on the upper end of the flange 40, respectively, and an operation piece 43 is provided on the lower end of the surface of the flange 40 in a forward direction. Therefore, in order to attach the ball introduction trough 38 to the reference plate 3, first, the locking portions 42, 42 are respectively locked in the upper locking holes 44, 44 formed in the reference plate 3, and then the operation piece 43 is fixed to the reference plate 3. The locking claw 41 is locked in the lower locking hole 45 of the reference plate 3 by pressing it toward the 3 side. On the other hand, sphere introduction gutter 38
To remove from the reference plate 3, the operation piece 43 is pushed down with a finger. When the operation piece 43 is pushed down, the tip of the locking claw 41 rises, so that the locking claw 41 comes off the lower locking hole 45,
The ball introduction trough 38 can be removed from the reference plate 3.

In the sphere supply device 9 having the above-mentioned configuration, the upper plate 25
When the balls are thrown in, the balls flow into the ball introduction trough 38 through the introduction port 39 of the panel in a state of being aligned in one row, and the first ball fits into the groove 37 of the sprocket 32. Launching device 8
When the solenoid 12 of is demagnetized, the plunger
Since 10 moves backward and presses the lower end of the swing rod 26 (second
(Solid line in the figure), the transmission rod 28 moves forward against the bias of the spring 35, and the upper claw portion 30 of the claw member 29 engages with the groove 37 of the sprocket 32 to prevent the sprocket 32 from rotating. Therefore, the frontmost ball in the ball introducing trough 38 is stopped while being fitted in the groove 37 of the sprocket 32. In this state, when the plunger 10 is moved forward by exciting the solenoid 12, the transmission rod 28 is urged by the spring 35 so that the first stopper piece 33 causes the stopper projection 36.
As the claw member 29 rotates clockwise in FIG. 2, the upper claw portion 30 retracts and disengages from the groove 37 of the sprocket 32, and the lower claw portion 31 advances and the sprocket 32 moves. Into the other groove 37 of. Thus, when the upper claw portion 30 is disengaged from the groove 37 portion of the sprocket 32, the sprocket 32 is rotated by the own weight of the ball fitted in the other groove 37 portion located in the ball introducing trough 38, Allow the ball to flow down. This sphere is a groove
When the sprocket 32 rotates until it disengages from the 37 part, the lower claw part 31 engages with the groove 37 part, and the rotation of the sprocket 32 stops. Therefore, when the plunger 10 of the solenoid 12 moves forward once, the sprocket 32 flows down only one ball in the ball introducing trough 38. The ball that has flowed down falls from the outlet 38b of the ball introduction trough 38 onto the launch rail 5, rolls due to the inclination of the launch rail 5, and stops at the launch position 7. When the solenoid 12 is demagnetized, the plunger 10 which has been moved forward is retracted by the urging force of the return spring 10 ', so that the rear end of the retracted plunger 10 presses the lower end of the swing rod 26, and the swing rod 26 is pushed. Swing 26 against the bias of spring 35. When the oscillating rod 26 oscillates, the transmission rod 28 advances, so that the pawl member 29
2 rotates counterclockwise in FIG. 2 to move the upper claw 30 forward and the lower claw 31 backward. When the lower claw portion 31 retreats, it is disengaged from the sprocket 32, so that the sprocket 32 slightly rotates due to the weight of the ball, but the upper claw portion 30 that has moved forward immediately stops rotating. Therefore, the ball fitted in the groove 37 located in the ball introducing trough 38 does not come off from the groove 37. In this way, when the solenoid 12 is excited once and the plunger 10 is reciprocated once, the sphere supply device 9 is actuated once by the reciprocating movement of the plunger 10, and the sphere introducing trough 38 introduced from the upper plate 25 is introduced. It is possible to supply one of the balls to the firing position 7. Then, when the sphere supplied by the sphere supply device 9 is stopped at the firing position 7, the solenoid 12 is re-energized, so that the resilient part 11 that has advanced together with the plunger 10 fires the sphere at the previously supplied firing position 7. . Thus, each time the solenoid 12 of the launch device 8 is excited, that is, the launch device 8 moves the ball 1
Every time an individual ball is shot, the ball feeding device 9 reliably feeds one ball introduced from the upper plate 25 to the firing position 7.

If a shock absorbing member 46 such as urethane rubber is attached to the portion where the rear end of the plunger 10 and the lower end of the swing rod 26 come into contact with each other, shock and vibration can be mitigated and the operating noise can be reduced. it can. Similarly, the stopper protrusion 36 and the first
If the cushioning member 47 is attached to the portion where the stopper piece 33 and the second stopper piece 34 come into contact with each other, shock, vibration, and operation noise can be reduced.

The hit ball shot by the above-described launching device 8 is the game board 4 from the launch rail 5 through the guide rail 48 as in the conventional case.
Entered into the game part 49 formed on the surface of, and flowed down while being deflected by an obstacle nail while changing the direction of flow, entering any prize device 50 became a safe ball and did not enter any prize device 50 The thing enters the out mouth 51 and becomes an out ball. When the hit ball enters the prize winning device 50, a prize ball discharging device (not shown) provided on the back side of the game board 4 is activated to discharge a predetermined number of balls to the upper plate 25 or the lower plate 52 as prize balls. . As described above, the balls discharged to the upper plate 25 are supplied to the firing position 7 by the operation of the ball supply device 9 and are sequentially emitted by the operation of the emitting device 8. However, when the balls are filled in the upper plate 25, the prize is given. The balls overflow from the prize ball discharge gutter to the lower tray 52 via the overflow gutter 53.
Then, when the lower plate 52 is filled with the balls and the balls are accumulated at the lower end portion of the overflow gutter 53, the over-reservation detection mechanism detects the balls,
The operation of the ball supply device 9 is stopped and the firing of the hit ball is stopped.

As shown in FIG. 2, the over-reservoir detection mechanism is such that the lower end portion of the overflow gutter 53 is rotatably faced with a plate-shaped sphere detection portion 54, and one end is connected to the upper end of the sphere detection portion 54. The other end of 55 is made to face a receiving pin 56 protruding from the lower end of the swing rod 26 of the ball supply device 9. In the over-reservoir detection mechanism having such a structure, the ball rod 54 is not pressed by the ball rod in the state where the ball can be further stored in the lower tray 52, so that the operating rod 55 is located on the left side in FIG. The other end of 55 is separated from the receiving pin 56 of the ball supply device 9. Therefore, the ball supply device 9 is activated each time the launch device 8 is activated to supply one ball to the launch position 7 to enable a game. On the other hand, when prize balls are accumulated in the lower plate 52 and become full, the balls press the ball detecting section 54, and the ball detecting section 54 rotates to move the operating rod 55 to the right side in FIG. When the operating rod 55 moves to the right, the other end presses the receiving pin 56,
The swing of the swing rod 26 is restricted. Therefore, the rocking rod 26 remains stopped even when the launching device 8 is activated, and the launching position 7
The supply of balls to the game is stopped, and the game is temporarily stopped. When the ball in the lower plate 52 is removed, the ball detecting section 54 returns and rotates to move the operating rod 55 to the left side in FIG. 2, so that the swing rod 26 returns to the swingable state again. It is possible to restart the game.

<Effects of the Invention> As described above, according to the present invention, even if the solenoid is subjected to impact or vibration at the time of repulsion, the mounting base is slightly moved in the longitudinal direction of the guide pin by the guide of the guide pin. It just moves. Therefore, the elastic unit always reciprocates on the same straight line, and does not affect the positional relationship between the ball and the elastic unit. For this reason, stable firing can always be performed, and the firing direction of the hit ball and the flight distance are stable.

Further, even if the solenoid vibrates to some extent in the length direction of the guide pin together with the mounting base, the cushioning material absorbs this vibration. Therefore, the vibration is not transmitted to the firing operation handle, and the player does not feel uncomfortable vibration. Therefore, the player can always enjoy a comfortable pachinko game.
