[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a game ball launcher that launches a game ball (so-called pachinko ball) used in a game board (so-called pachinko).
[0002]
[Prior art]
  Conventionally, as a game ball launching device for launching a game ball made of metal (steel ball), a synchronous motor system, a step motor system, a rotary solenoid system, and a linear solenoid system are provided.
[0003]
  By the way, in the game ball launching device, it can be repeated 50 million times to 100 million times, the ball flight distance of the game ball can be arbitrarily changed by the handle operation, and the position of the handle is kept constant. However, it is required that the ball flight distance is constant and does not vary, that there are few shocks and operation sounds when hitting the ball, and that there is no unevenness of the ball flight for each unit without adjustment during mass production. In addition, the frequency of play balls per minute on the game board is set to 100 shots / minute or less, and it is fired at a frequency very close to 100 shots / minute within a range not exceeding 100 shots / minute. It has become.
[0004]
  When considering the above requirements, the synchronous motor type, step motor type, and rotary solenoid type game ball launching devices have a problem that the ball flight distance becomes unstable because the trajectory of the rotating lever and the game ball launch direction are shifted. . On the other hand, in the linear solenoid type game ball launching device, as shown in FIG. 41, the moving direction of the output shaft 5 of the solenoid body A (the direction of the arrow C in FIG. 41) and the launching direction of the game ball B (FIG. 41). (The direction of the arrow D in the middle) coincides at the time of launch, and there is an advantage that the ball flight distance is stabilized. A conventionally proposed linear solenoid type game ball launcher will be described below.
[0005]
  (Conventional example 1)
  As shown in FIG. 42, this type of game ball launcher includes a coil bobbin 2 that is cylindrical and has a coil 1 wound around it and has flanges 2a at both ends, a yoke 3a that houses the coil bobbin 2, By energizing the coil 1, a yoke 3 b that is caulked and coupled to the yoke 3 a so as to cover the opening surface of the yoke 3 a, a plunger 4 that is inserted into the through hole 2 c of the coil bobbin 2 and reciprocates linearly between two specified positions, and An output shaft 5 that cooperates with the plunger 4 to fire a play ball set in advance at a predetermined position of the game board in the vicinity of one of the two positions, and the output shaft 5 is the other position of the two positions. A return spring 10 made of a coil spring for returning the plunger 4 to the initial position, a bearing 6 for inserting one end of the output shaft 5 and slidably supporting the output shaft 5, and a plunger 4 are inserted. And a bearing 6 'for supporting the plunger 4 slidably.
[0006]
  By the way, the output shaft 5 has an ejecting member 9 made of an elastic body attached to one end portion on the side inserted into the bearing 6 and the other end portion press-fitted into the plunger 4. Here, the plunger 4 moves back and forth linearly at a frequency of, for example, about 100 times per minute by controlling energization to the coil 1. The weight of the plunger 4 is about 20 g to 30 g.
[0007]
  The return spring 10 is held between the yoke 3a and a disk-like plate 15 integrated with the plunger 4. The output shaft 5 is provided with a first stopper 13 made of an elastic body in the vicinity of the launching member 9, and the plunger 4 is provided with a second stopper 14 made of an elastic body positioned by a plate 15. Yes.
[0008]
  Further, in this conventional example, the bearing 6 that supports the output shaft 5 can be moved in a direction orthogonal to the axial direction of the output shaft 5 in order to absorb the shaft misalignment of the two bearings 6 and 6 ′ during assembly. In this way, the bearing 6 is positioned by pressing the fixed iron core 12 with the fixing member 11 made of rubber.
[0009]
  In this conventional example, the yoke 3a and the yoke 3b also serve as the outer shell of the solenoid, and the yoke 3a has a mounting hole 33 for mounting to the game board using screws. Therefore, when this conventional game ball launcher is attached to a predetermined part of the game board, a screw is inserted into the attachment hole 33 and directly fixed to the game board with the screw. In such a configuration, the plunger 4 has no portion that absorbs the impact force applied to the yokes 3b and 3a via the stoppers 13 and 14, so that the yokes 3a and 3b, the stoppers 13 and 14 and the mounting portion are damaged, Excessive vibration and sound are generated on the game board, which is not practical, and actually requires an external buffer structure as in Conventional Example 3 described later.
[0010]
  Next, the basic operation will be described.
[0011]
  When the coil 1 is not energized, the plunger 4 is in the predetermined initial position shown in FIG. 43 (c) by the spring force of the return spring 10, and when the coil 1 is energized with a predetermined exciting current, the plunger 4 is moved to the yoke 3b. As shown in FIG. 43 (a), it moves toward the fixed iron core 12 against the spring force of the return spring 10 (accelerates). At a position near the end of the acceleration operation, the launching member 9 collides with a game ball set in advance at a predetermined position on the game board, and the game ball is launched. Thereafter, the second stopper 14 collides with the yoke 3a as shown in FIG. Thereafter, the plunger 4 returns to the initial position by the spring force of the return spring 10 and stops at the initial position when the first stopper 13 collides with the yoke 3b.
[0012]
  (Conventional example 2)
  As another game ball launching device of this type, as shown in FIG. 44, a coil bobbin 2 that is cylindrical and has a coil 1 wound around it and has flanges 2a at both ends, and a yoke 3a that houses the coil bobbin 2 A yoke 3b that is caulked and coupled to the yoke 3a so as to cover the opening surface of the yoke 3a, a cylindrical guide pipe 8 that is inserted into the through hole of the coil bobbin 2, and a through hole 8c of the guide pipe 8 that is slidable. The plunger 4 is inserted into the first and second reciprocating linear movements between two specified positions, and the coil 4 is energized with the plunger 1 and is set in advance at a predetermined position on the game board in the vicinity of one of the two positions. An output shaft 5 for firing a game ball, a return spring 10 comprising a coil spring for returning the plunger 4 to an initial position where the output shaft 5 is the other of the two positions, and an output Both ends of the 5 is equipped with two bearings 6,6 for supporting freely inserted through sliding the output shaft 5, respectively, and a bearing holder 7, 7 for holding the bearings 6,6.
[0013]
  The bearing holders 7 and 7 have disk-like flange pieces 7a and 7a, and are fixed to the yokes 3a and 3b. Both end portions of the guide pipe 8 are inserted into the coupling holes of the bearing holders 7 and 7 and positioned. That is, the guide pipe 8 is used to improve the positioning accuracy of the bearings 6 and 6. Each yoke 3a, 3b has an insertion hole through which the guide pipe 8 is inserted. By the way, an ejecting member 9 made of an elastic body is attached to one end of the output shaft 5.
[0014]
  Also in this conventional example, the yoke 3a and the yoke 3b also serve as the outer shell of the solenoid, and the yoke 3a is continuously integrated with a mounting piece 31 in which a mounting hole 33 for mounting to a play board using screws is drilled. It is extended to. Therefore, when this conventional game ball launcher is attached to a predetermined part of the game board, a screw is inserted into the attachment hole 33 and directly fixed to the game board with the screw.
[0015]
  Next, the basic operation will be described.
[0016]
  When the coil 1 is not energized, the plunger 4 is in the predetermined initial position shown in FIG. 45 (d) by the spring force of the return spring 10, and when the coil 1 is energized with a predetermined exciting current, the plunger 4 is moved to the yoke 3a. As shown in FIG. 45A, it moves to the left in FIG. 45A against the spring force of the return spring 10 (accelerates). At a position near the end of the acceleration operation, the launching member 9 collides with a game ball set in advance at a predetermined position on the game board, and the game ball is launched. Thereafter, when the plunger 4 moves away from the yoke 3b as shown in FIG. 45 (b), a suction force acts in the opposite direction to that before and the moving speed of the plunger 4 is decelerated (decelerates). Thereafter, the plunger 4 moves in a direction to return to the initial position by the spring force of the return spring 10 as shown in FIG. 45 (c), and the stopper 13 collides with the bearing holder 7 as shown in FIG. 45 (d). To stop at the initial position.
[0017]
  (Conventional example 3)
  By the way, as a configuration for preventing the impact and sound accompanying the operation of the game ball launching device from being transmitted to the game ball main body, the solenoid itself is movable with respect to the game board, for example, a buffer as shown in FIG. 46 and FIG. Proposals have been proposed in which members 47 and 48 are provided to absorb the impact (for example, Japanese Patent Publication No. 61-29375, Japanese Patent Publication No. 62-292184, Japanese Patent Publication No. 2-82990, Japanese Patent Publication No. 2). -Ref. -88090). In addition, the same code | symbol is attached | subjected to the component similar to the prior art example 1. FIG.
[0018]
  In this game ball launching device, a certain number of signals are sent at a certain time by manipulating an operating means (not shown), and at the same time, a power source is energized to perform a hitting operation and play.
[0019]
  In this operation, when the solenoid body A is excited and starts firing, the launching member 9 enters the starting end, fires the previously set game ball B, and simultaneously makes the second stopper 14 collide with the case body 60. The protruding amount of the projecting member 9 is regulated. When the plunger 4 is returned by the return spring 10 due to demagnetization, the first stopper 13 collides with the case body 60 to determine the retracted position. As a result, the stopper 4 is hit by both the stoppers 13 and 14. The strokes are made uniform, and the flying distances of the game balls B under a constant current are made uniform.
[0020]
  When the plunger 4 reciprocates linearly, when the second stopper 14 collides with the case body 60, the buffer member 48 is compressed to absorb the impact, and then the plunger 4 is returned by the return spring 10. The shock of the first stopper 13 is absorbed by the other shock absorbing member 47, and vibrations and accompanying noises that are applied to the game board through the mounting frame 50 and the mounting substrate 100 are automatically absorbed.
[0021]
  (Conventional example 4)
  The basic configuration of this conventional example is substantially the same as that of the conventional example 1, and in order to restrict the rotation of the plunger 4, the end portions of the end winding portions at both ends of the return spring 10 are provided as shown in FIGS. The protrusions 10c and 10c are formed by raising vertically, and one of the protrusions 10c and 10c is inserted into the hole of the yoke 3a and the other is inserted into the hole of the plate 15 to prevent the plunger 4 from rotating. It is what I did. In addition, the same code | symbol is attached | subjected to the component similar to the prior art example 1, and description is abbreviate | omitted.
[0022]
  (Conventional example 5)
  The basic configuration of the conventional example is substantially the same as that of the conventional example 2, and in order to restrict the rotation of the plunger 4, as shown in FIGS. 51 and 52, the plunger 4 has a predetermined width over the entire length in the axial direction. The groove 4a is formed, a notch groove is formed in the guide pipe 8, and a projection 2b is provided on the inner peripheral surface of the through hole 2c of the coil bobbin 2 over the entire length in the axial direction. The projection 2b slides in the groove 4a of the plunger 4. In addition, the same code | symbol is attached | subjected to the component similar to the prior art example 2, and description is abbreviate | omitted.
[0023]
  (Conventional example 6)
  The basic configuration of the conventional example is substantially the same as that of the conventional example 2, and a part 5b ′ of the output shaft 5 is cut in the axial direction as shown in FIGS. 53 and 54 in order to restrict the rotation of the plunger 4. The plunger 4 is prevented from rotating by restricting the rotation of the output shaft 5 in accordance with the shape of the insertion hole of the bearing 6 and the shape of the cut.
[0024]
[Problems to be solved by the invention]
  However, in the game ball launching devices of the above-mentioned conventional examples 1, 2, 4, 5, and 6, since the structure for attaching to the game board is provided in the yoke 3a, when there are many types of game boards, If the shape of each mounting part is different, even if the components other than the yoke 3a, 3b such as the plunger 4 and the coil bobbin 2 are common, it is necessary to manufacture one kind of solenoid for each game board to be incorporated. As a result, the number of solenoids increased, and there were many problems in inventory management, delivery, and cost. In addition, depending on the shape of the mounting portion of the game board, the shapes of the yokes 3a and 3b may be complicated, and the workability of the sheet metal processing of the yokes 3a and 3b may be deteriorated and the cost may be increased.
[0025]
  Further, in the conventional examples 1 and 4, since one bearing 6 is press-fitted and fixed by the fixing member 11 made of an elastic body, it is difficult to adjust the positional accuracy of the output shaft 5 at the time of assembly. In some cases, an external force is applied to the output shaft 5 after the assembly, and the position of the bearing 6 is shifted. Further, in the conventional examples 1 and 4, since a part of the output shaft 5 is press-fitted into the central portion of the plunger 4 so that the axial directions thereof coincide with each other, the component machining accuracy of each of the plunger 4 and the output shaft 5 is increased. In addition to the need for improvement, it is necessary to manage the process so that the output shaft 5 does not tilt in the process of press-fitting the output shaft 5 into the plunger 4, which is troublesome.
[0026]
  In the conventional examples 2, 5, and 6, since the flange pieces 7a and 7a of the bearing holders 7 and 7 are fixed to the yokes 3a and 3b, the surfaces that contact the flange pieces 7a and 7a of the yokes 3a and 3b. When the accuracy of the parallelism between the bearings is low, there is a problem that the bearings 6 and 6 are displaced. Further, in the conventional examples 2, 5, and 6, the guide pipe 8 is used to obtain the coaxiality of the two bearings 6 and 6, but the bearing holders 7 and 7 are fixed to the yoke 3a whose shape is unstable. Therefore, there was a problem that the coaxiality could not be increased so much.
[0027]
  In the conventional examples 1 and 4, when the plunger 4 is attracted and accelerated by the yoke 3b as shown in FIG. 43 (a), the second stopper 14 collides with the yoke 3a as shown in FIG. 43 (b). When the first stopper 13 collides with the yoke 3b as shown in FIG. 43 (c), an impact is applied to the yokes 3a and 3b, and vibrations are transmitted to the game board and noise is generated. There was a risk of discomfort to the player.
[0028]
  In the conventional examples 2, 5, and 6, when the plunger 4 is attracted to the yoke 3a and accelerated as shown in FIG. 45 (a), the direction of the suction force acting on the plunger 4 as shown in FIG. 45 (b). 45, when the first stopper 13 collides with the bearing holder 7 as shown in FIG. 45 (d), an impact is applied to the yokes 3a and 3b, and vibration is transmitted to the game board and noise is generated. There was a risk of discomfort to the player.
[0029]
  In order to avoid this type of problem, the configuration of the conventional example 3 can be cited. In the configuration of the conventional example 3, the buffer members 47, 48, the mounting frame 50, etc. are disposed around the case body 60 of the solenoid. Since space is required and the number of parts increases, there is a problem that the cost of parts increases and the work of attaching to the play board becomes troublesome. Further, in Conventional Example 3, since the case main body 60 is semi-fixed with rubber or the like, the setting position of the case main body 60 tends to become unstable, and when the setting position is shifted, the launching member 9 collides with the game ball. Since the stroke position of the plunger 4 at the time is shifted, there is a problem that the force transmitted to the play ball varies and the play distance of the play ball varies.
[0030]
  In the conventional example 4, the return spring 10 made of a coil spring is used to restrict the rotation of the plunger 4. However, since the return spring 10 has a certain degree of freedom in the rotation direction, There was a problem that rotation could not be completely prevented. In addition, since the protrusions 10c and 10c of the end winding portion of the return spring 10 are merely inserted into the holes of the plate 15 and the yoke 3a, the protrusion 10c is pulled out of the hole by the vibration of the return spring 10 or external force during transportation. There was a case where I missed it. Further, since the process of forming the protrusion 10c needs to be raised at a right angle to the direction of the end turn, the process is troublesome, and the problem is that the end turn part is deformed and the cost of the return spring 10 is increased. was there.
[0031]
  Further, in Conventional Example 5, since the groove 4a of the plunger 4 and the protrusion 2b of the coil bobbin 2 slide, the sliding resistance affects the moving speed of the plunger 4 and the ball jumping unevenness is likely to occur. was there. In addition, since the magnetic path cross-sectional area is reduced by forming the groove 4a in the plunger 4, there is a problem that the launch force of the play ball (the play distance of the play ball) is reduced. In addition, there is a problem that the life of the solenoid is shortened due to generation of wear powder by sliding. Moreover, in the prior art 5, since it is necessary to form the notch groove for inserting the said protrusion part 2b in the guide pipe 8, the malfunction that the precision of alignment of a bearing 6 (coaxiality adjustment) will deteriorate. there were.
[0032]
  In addition, the conventional example 6 is characterized in that a part 5b ′ of the cylindrical output shaft 5 is cut so as to have a D-shaped cross section, but such a cutting process is difficult, and after the cutting is performed. However, since it is difficult to perform centerless polishing or the like on the cut surface, the surface roughness of the processed surface cannot be increased, and the manufacturing cost of the output shaft 5 becomes very high. Furthermore, since it is necessary to match the cross-sectional shape of the insertion hole of the bearing 6 to the cut-shaped cross-section of the output shaft 5, the surface roughness of the sliding surface cannot be increased on both the output shaft 5 side and the bearing 6 side. There was a problem that dynamic wear was likely to occur and it was difficult to extend the service life.
[0033]
  The present invention has been made in view of the above reasons.Its purpose is lowCost can be reducedAnd can stabilize the flight distance of the play ball at a low cost, and is transmitted to the play board.An object of the present invention is to provide a low-cost game ball launching device with low vibration and impact.
[0034]
[Means for Solving the Problems]
  ContractClaim1The present invention is a cylindrical bobbin that is wound with a coil and has flanges at both ends, a yoke that houses the coil bobbin, and a reciprocating linear movement between two specified positions inserted into a through hole of the coil bobbin. A plunger, an output shaft for cooperating with the plunger in response to the excitation of the coil, and firing a game ball preset in a predetermined position of the game board in the vicinity of one of the two positions; A solenoid body comprising a return spring that returns the plunger to an initial position that is the other of the positions, and two bearings through which both ends of the output shaft are inserted and slidably supported. The solenoid body is housed in the internal space, and is provided with a housing that is fitted in accordance with the shape of the mounting area of the game board. The housing is attached using screws to the mounting area of the game board. In the case of the game ball launcher for each user, which is characterized in that a mounting hole for attaching is provided, and the characteristics required for the solenoid body are the same and only the structure of the mounting part of the game board is different, Since the structure of the solenoid body can be made common and the change can be made by changing only the housing, the cost can be reduced. Moreover, since the housing does not need to form a magnetic path, there are few restrictions on the shape and material, and if the housing is formed of resin, it can be used for a complicated mounting structure, and can be reduced in cost and weight. Can be achieved. Further, if the housing is made of a metal such as zinc, brass, or aluminum, the specific gravity is larger and the weight is increased as compared with the case of resin, so that the impact transmitted from the solenoid body to the game board can be reduced. Further, since the housing is provided, it is not necessary to process the yoke in accordance with the shape of the attachment portion of the play board as in the conventional example, so that the cost required for processing the yoke and the assembling cost can be reduced.
[0035]
  In addition,Claim1DepartureIn the morning,Inserted into the through hole of the ilbobineRepSince it has a cylindrical guide pipe into which the ranger is inserted, and each bearing is built in at both ends of the guide pipe, the coaxiality of the two bearings is determined only by the precision of the parts of the bearing holder and the guide pipe. Since the high degree of coaxiality of the bearings can be obtained, the output shaft is not twisted due to the deviation of the coaxiality of the two bearings, and the flying distance of the play ball can be stabilized at low cost.
[0036]
  In addition,Claim1DepartureIn the morning,A yoke block composed of a coil and a yoke is movable relative to the housing in a direction parallel to the direction of movement of the output shaft, and a buffer member made of an elastic body that restricts movement of the yoke block is provided on both sides of the direction of movement of the yoke block. Since it is provided, the yoke block can be moved and its movement is regulated by the buffer member, so that vibration and impact sound transmitted to the game board through the yoke with the reciprocating linear movement of the plunger can be reduced at low cost. And it is possible to provide a player with a comfortable game for a long time..
[0037]
  In addition,Claim1DepartureIn the morning, eachEach bearing is supported by the housing, and a guide pipe block composed of the bearing and the guide pipe is movable with respect to the housing in a direction parallel to the moving direction of the output shaft, and there is a weight that cooperates with the guide pipe block in the housing. A buffer member made of an elastic body that is provided on the other side of the two positions and restricts the movement of the weight is provided between the weight in the moving direction and the housing, so that the guide pipe block can be moved. As a result, vibration and impact sound transmitted from the guide pipe block to the game board through the case can be reduced, and it becomes possible to provide a player with a comfortable game for a long time. By providing a weight that moves together with the block, the plunger and the output shaft The displacement of the guide pipe block due to the rebound of the plunger block and the collision of the plunger can be suppressed, and the vibration transmitted from the guide pipe block to the game board through the housing by using a low hardness as the buffer member, The impact sound can be further reduced.
[0038]
  Claim2The invention of claim1In the invention, the shock-absorbing member made of an elastic body that restricts the movement of the weight is arranged in a cylindrical shape so that the output shaft and the axial direction coincide with each other and bends when the shock-absorbing member is compressed and deformed Since at least one of the outer peripheral surface and the inner peripheral surface is provided with a gentle projecting portion, the projecting portion has a smooth projecting portion on at least one of the outer peripheral surface and the inner peripheral surface at a portion that is bent during compression deformation of the buffer member. By providing this, local wear during compression deformation of the buffer member can be suppressed at a low cost, the life can be extended, and local wear during compression deformation of the buffer member can be suppressed. Since the amount of compressive deformation of the buffer member can be increased and the amount of displacement of the guide pipe block can be increased compared to the case where there is no protrusion, the guide pipe block Vibration transmitted to game machine along the housing, it is possible to further reduce impact noise.
[0039]
DETAILED DESCRIPTION OF THE INVENTION
  (Reference Example 1)
  Of this reference exampleAs shown in FIG. 1, the game ball launcher includes a coil bobbin 2 that is cylindrical and has a coil 1 wound around it and has flanges 2 a at both ends, a yoke 3 a that houses the coil bobbin 2, and an opening of the yoke 3 a. The yoke 3b combined with the yoke 3a so as to cover the surface, the plunger 4 inserted in the through hole 2c of the coil bobbin 2 and reciprocatingly moved between two predetermined positions, and the plunger 4 in response to excitation of the coil 1 An output shaft 5 that moves and fires a play ball set in advance at a predetermined position of the game board in the vicinity of one of the two positions, and an initial position where the output shaft 5 is the other of the two positions. A solenoid spring A for returning the plunger 4 and two bearings 6 and 6 through which both ends of the output shaft 5 are inserted to support the output shaft 5 slidably. And a housing 20 for mounting in accordance with the shape of the mounting portion of the game board while accommodating. The return spring 10 is a coil spring and is held between the plunger 4 and the inner surface of the housing 20.
[0040]
  The output shaft 5 is integrated through the plunger 4, and both end portions thereof are supported by the bearings 6 and 6 and protrude from the housing 20. Here, the plunger 4 moves back and forth linearly, for example, at a frequency of 100 times per minute by controlling energization to the coil 1. Further, a launching member 9 made of an elastic body that collides with the play ball when the output shaft 5 moves is attached to one end of the output shaft 5. Further, the output shaft 5 is provided with a stopper 13 made of an elastic body in the vicinity of the launching member 9. Here, the stopper 13 has a function of regulating the movement range of the plunger 4 in the direction in which the return force of the return spring 10 acts.
[0041]
  As shown in FIG. 3, the stopper 13 is continuously and integrally extended from a disc-shaped stopper main body portion 13a in which a hole 13c into which the output shaft 5 is press-fitted is formed in the central portion, and the periphery of the stopper main body portion 13a. It consists of a strip-shaped anti-rotation part 13b for preventing the stopper main body part 13a from rotating. Here, the stopper 13 co-operates with the output shaft 5, but the rotation preventing portion 13 b slides on the inner surface of the guide groove 24 a of the U-shaped guide portion 24 that is continuously extended from the housing 20. Therefore, the rotation of the stopper 13 is prevented, and as a result, the output shaft 5 and the plunger 4 are prevented from rotating. Accordingly, by appropriately setting the width of the guide groove 24a and the width of the rotation preventing portion 13b, the output shaft 5 and the return spring 10 can be provided without providing the protrusion 10c (see FIG. 49) as in the conventional example 4. The rotation of the plunger 4 can be restricted. In addition, the magnetic path cross-sectional area does not decrease as in the case of preventing rotation by forming the groove 4a (see FIG. 51) in the plunger 4 as in the conventional example 5, so that the flying distance of the play ball is affected. Never give. Further, since it is not necessary to form the groove 4a in the plunger 4 or to provide the protrusion 2b on the coil bobbin 2, the rotation of the output shaft 5 can be prevented at a low cost, and the flying distance of the play ball can be reduced. It can be stabilized.
[0042]
  by the way,In this reference exampleThe stopper 13 is formed of an elastic body such as rubber. The material of the stopper 13 is strong enough not to come out of the narrow portion 5c of the output shaft 5 due to an impact when it collides with the housing 20, and the guide groove It is desirable to use a material that has a small frictional resistance when sliding on the inner surface of 24a and has little wear.
[0043]
  Moreover, although the housing 20 is comprised by couple | bonding the division body 20a and the division body 20b, what is necessary is just to set the shape of the division bodies 20a and 20b suitably according to the shape of the attachment part of a game board.
[0044]
  As shown in FIG. 4, the yokes 3a and 3b are crimped by fitting the protruding portions 3h and 3h formed on the rectangular plate-shaped yoke 3b into the notches 3g and 3g formed on the U-shaped yoke 3a. But you canIn this reference exampleThe yokes 3a and 3b are positioned by being accommodated in the internal space of the rectangular parallelepiped housing body 27 of the housing 20, so that it is not necessary to perform caulking. Instead of the yokes 3a and 3b, for example, as shown in FIG. The so-called horizontal split yokes 3c and 3d having a U-shape can be used, or so-called vertical split yokes 3e and 3f having a U-shape can be used as shown in FIG. Also good. If the shape is not caulked in this way, the yoke forming process can be simplified.
[0045]
  The housing 20 has projecting portions 25 projecting from both end portions of the housing body 27, and the bearing 6 is disposed in the vicinity of the central portion of the tip portion of each projecting portion 25. The housing 20 is provided with an attachment piece 26 that matches the shape of the attachment part of the game board. The attachment piece 26 is provided with fixing holes 22 for fixing the divided bodies 20a and 20b. The hole 22 is used as an attachment hole for attaching to the attachment part of the game board using screws or the like.
[0046]
  Since the housing 20 does not need to form a magnetic path, there are few restrictions on the shape and material, and if the housing 20 is made of resin, it can be easily molded and can cope with a complicated mounting structure. Cost reduction and weight reduction can be achieved. In short, as compared with the case where the yoke 3a is provided with a structure for mounting on a play board as in the conventional examples 1, 2, 4, 5, 6, it is possible to cope with a more complicated mounting structure. Further, if the housing 20 is made of a metal such as zinc, brass, or aluminum, the specific gravity is larger and the weight is increased as compared with the case where the housing 20 is made of resin, so that the impact transmitted from the solenoid body A to the game board is reduced. Can do.
[0047]
  Moreover, since the housing 20 can be processed by resin integral molding or die casting, and the bearings 6 and 6 can be fixed by the housing 20, the yoke 3a having an unstable shape as in the conventional examples 1, 2, 4, 5, and 6 is used. Compared with the case where the bearing 6 and the bearing holder 7 are fixed to 3b, the coaxiality of the two bearings 6 and 6 can be easily obtained, so that the twisting of the output shaft 5 can be reduced and the reciprocating linear movement operation can be performed. The flying distance of the game ball can be stabilized stably.
[0048]
  In this reference exampleFIG. 7 shows a common structure of the solenoid body A in the case of a game ball launcher for each user that has the same characteristics required for the solenoid body A but is different only in the structure of the game board mounting portion. Since it is possible to cope with the shape change of only 20, it is possible to reduce the cost. In the game ball launching apparatus shown in FIG. 7, mounting portions 21 and 21 are integrally formed on the housing 20 of FIG. 1 in accordance with the shape of the mounting portion of the game board, and the game board is attached to the mounting portions 21 and 21. A mounting hole 23 is drilled in the site using a screw or the like.
[0049]
  Next, the operation of the game ball launcher configured as shown in FIG. 1 will be described.
[0050]
  When the coil 1 is not energized, the plunger 4 is in the predetermined initial position shown in FIG. 2D by the spring force of the return spring 10, and when the coil 1 is energized with a predetermined exciting current, the yoke 3 and the plunger 4 The plunger 4 is attracted by the yoke 3a and moves to the left in FIG. 2A against the spring force of the return spring 10 as shown in FIG. 2A (acceleration operation). To do). At a position near the end of the acceleration operation, the launching member 9 collides with a game ball set in advance at a predetermined position on the game board, and the game ball is launched. In addition, the arrow shown with the dashed-dotted line in Fig.2 (a) has shown the flow of magnetic flux.
[0051]
  After that, as shown in FIG. 2B, when the rear end of the plunger 4 (the end far from the launching member 9) passes through the insertion hole of the yoke 3b, the rear end of the plunger 4 and the yoke 3b In the meantime, the suction force acts to decelerate the plunger 4, and as a result, the direction in which the plunger 4 moves in the opposite direction (that is, the direction in which the plunger 4 returns to the initial position) changes. In addition, the arrow shown with the dashed-dotted line in FIG.2 (b) has shown the flow of magnetic flux.
[0052]
  Thereafter, as the plunger 4 returns to the initial position, a gap is formed between the front end of the plunger 4 (the end close to the launching member 9) and the yoke 3a as shown in FIG. Since a suction force is generated, the plunger 4 returns to the initial position while decelerating. In addition, the arrow shown with the dashed-dotted line in FIG.2 (c) has shown the flow of magnetic flux.
[0053]
  Thereafter, the plunger 4 returns to the initial position by the suction force toward the initial position and the return force of the return spring 10, and the stopper 13 attached to the output shaft 5 collides with the housing 20, and is shown in FIG. Thus, the plunger 4 stops at the initial position.
[0054]
  (Reference Example 2)
  Of this reference exampleBasic configuration of the game ball launcherIs Reference Example 18 to 10, a cylindrical guide pipe 8 is inserted into the through hole 2c of the coil bobbin 2, and the wide portions of the bearing holders 7 and 7 holding the bearings 6 and 6 are guided. The pipe 8 is fitted at both ends, and the narrow base ends of the bearing holders 7 and 7 are supported by the housing 20. Here, the divided bodies 20a and 20b constituting the housing 20 are formed with recesses for positioning and holding the base end portions of the bearing holders 7 and 7 when they are combined with each other. Therefore, by combining the divided bodies 20a and 20b, the position of the housing 20 and the guide pipe block composed of the bearings 6 and 6, the bearing holders 7 and 7, and the guide pipe 8 can be fixed. The return spring 10 is held between the bearing holder 7 and the plunger 4 on the side close to the launching member 9.
[0055]
  For this reason,In this reference exampleSince the positioning accuracy (coaxiality) of the bearings 6 and 6 is determined only by the component accuracy of the bearing holders 7 and 7 and the guide pipe 8, it can be managed with high accuracy and the shaft target accuracy can be easily obtained. it can. In short, since the high coaxiality of the two bearings 6 and 6 can be obtained, the malfunction such as the twisting of the output shaft 5 due to the deviation of the coaxiality of the two bearings 6 and 6 is eliminated, and the flight distance of the game ball is stabilized.In this reference exampleSince the coaxiality of the bearings 6 and 6 can be increased with a small number of parts and a simple structure, the parts cost is low, and the twisting of the output shaft 5 is reduced, so that the yield during assembly is improved. In additionReference example 1The same components as those in FIG. Also, basic operationReference example 1The explanation is omitted because it is the same as.
[0056]
  Also, with respect to the coaxiality of the plunger block itself composed of the plunger 4 and the output shaft 5, since two locations of the single output shaft 5 are supported by the two bearings 6, 6, even the straightness of the output shaft 5 is What is necessary is just to come out, and a very highly accurate thing can be obtained at low cost. Therefore,In this reference exampleSince the basic coaxial accuracy is high, it is possible to reduce the clearance between the inner diameters of the bearings 6 and 6 and the outer diameter of the output shaft 5, and the backlash of the output shaft 5 can be reduced. Wear is less likely to occur, stable solenoid characteristics can be obtained, and a longer life can be achieved.
[0057]
  Note that the material of the bearing holder 7 may be a resin or a metal as long as it is a non-magnetic material that does not affect the magnetic path. Also,In this reference exampleThe bearing 6 and the bearing holder 7 are formed separately, and the bearing 6 is press-fitted into the bearing holder 7. By using a material suitable for the bearing 6 as the bearing holder 7, the bearing holder 7 is replaced with the bearing 6. And may be integrated.
[0058]
  As the guide pipe 8, a drawing material such as brass which is easy to obtain coaxial accuracy and is nonmagnetic and inexpensive can be used. The material of the guide pipe 8 is not limited to brass, and may be any nonmagnetic material that can be easily processed by pipes.
[0059]
  (Reference Example 3)
  Of this reference exampleBasic configuration of the game ball launcherIs Reference Example 1As shown in FIG. 11, a yoke block including yokes 3 a and 3 b and a coil bobbin 2 around which the coil 1 is wound is arranged in the axial direction of the output shaft 5 inside the housing main body 27 of the housing 20. It is characterized in that it can move in parallel directions. Here, the yoke 3a is U-shaped formed by sheet metal bending, and the yokes 3a and 3b are joined together by caulking or the like by combining the flat yokes 3b.
[0060]
  A clearance is provided between the inner diameter dimension of the through hole 2 c (see FIG. 12) of the coil bobbin 2 and the outer diameter dimension of the guide pipe 8 so that the coil bobbin 2 can move on the outer peripheral surface of the guide pipe 8. Accordingly, the coil bobbin 2 is movable on the outer peripheral surface of the guide pipe 8 integrally with the yokes 3a and 3b. That is, the yoke block is movable on the outer peripheral surface of the guide pipe 8. Here, if the material of the coil bobbin 2 is made of a resin having good slidability, sliding wear with the guide pipe 8 is reduced, and the life can be extended.
[0061]
  Also,In this reference exampleIs provided with cushioning members 16 (see FIG. 13) made of an elastic body such as a cylindrical rubber at both ends of the guide pipe 8 so that the yoke block does not collide with the inner surface of the housing 20 in the moving direction. . Here, the buffer member 16 is inserted together with the guide pipe 8 into a hole formed in the projecting portion 25 of the housing 20, and one end portion in the axial direction projects into the internal space of the housing main body 27 of the housing 20. Therefore, the movement range of the yoke block is restricted by the buffer members 16 and 16, and it is possible to prevent the yoke block from directly colliding with the inner surface of the housing main body 27.
[0062]
  In addition,In this reference exampleSince the rubber formed in the cylindrical shape is used as the buffer member 16, the amount of deformation of the buffer member 16 can be increased, and the yoke can be formed without extremely reducing the rubber hardness as the physical property is unstable. The block can be displaced sufficiently.
[0063]
  Further, when rubber is used as the buffer member 16, it is made of a material having elasticity and hardness that has a stable physical property from low hardness to high hardness, such as silicon rubber, and can give an appropriate displacement to the yoke block. I just need it. Further, the buffer member 16 is not limited to rubber, and a spring made of a metal coil spring may be used.
[0064]
  Further, by making the inner diameters of the buffer members 16, 16 slightly larger than the outer diameter of the guide pipe 8, the inner peripheral surface of the buffer members 16, 16 can be smoothly deformed without sticking to the outer peripheral surface of the guide pipe 8. As a result, the yoke block can be moved stably.
[0065]
  next,Of this reference exampleThe operation of the game ball launcher will be described.
[0066]
  In a state where the coil 1 is not energized, the plunger 4 is at a predetermined initial position shown in FIG. 14 (d) by the spring force of the return spring 10, and the buffer member 16 is not deformed.
When a predetermined exciting current is applied to the coil 1, a magnetic flux is generated in the yoke 3 and the plunger 4, and the plunger 4 is attracted to the yoke 3a, and the spring force of the return spring 10 is increased as shown in FIG. In contrast, it moves to the left in FIG. 14 (accelerates). At this time, a reaction force is generated in the yoke block in the direction opposite to the direction in which the plunger 4 moves. However, the yoke block moves in the direction opposite to the direction in which the plunger 4 moves, and the buffer member 16 is deformed to buffer. Since the movement is restricted by the member 16, the reaction force to the yoke block is absorbed, and the vibration and impact transmitted to the housing 20 and the game board are alleviated.
[0067]
  At a position near the end of the acceleration operation, the launching member 9 collides with a game ball set in advance at a predetermined position on the game board, and the game ball is launched. In addition, the arrow shown with the dashed-dotted line in Fig.14 (a) has shown the flow of magnetic flux.
[0068]
  After that, as shown in FIG. 14B, when the rear end of the plunger 4 (the end far from the launching member 9) passes through the insertion hole of the yoke 3b, the rear end of the plunger 4 and the yoke 3 A gap is formed between them, and the plunger 4 is decelerated due to the suction force. As a result, the direction in which the plunger 4 moves in the opposite direction (that is, the direction in which the plunger 4 returns to the initial position) is changed. At the time of deceleration, the yoke block generates the suction force described above as a reaction force to the plunger 4 and is pulled by the plunger 4, so that a force in the same direction as the plunger 4 moves is applied, and the yoke block moves. Since the movement is restricted by the elastic deformation of the buffer member 16 on the side close to the punching member 9, it is possible to mitigate the impact generated in the yoke block from being transmitted to the housing 20 and the game board. In addition, the arrow shown with the dashed-dotted line in FIG.14 (b) has shown the flow of magnetic flux.
[0069]
  While the plunger 4 is reversed and returned to the initial position, a gap is formed between the front end of the plunger 4 (the end close to the launching member 9) and the yoke 3a as shown in FIG. Since a suction force is generated, the plunger 4 returns to the initial position while decelerating. In addition, the arrow shown with the dashed-dotted line in FIG.14 (c) has shown the flow of magnetic flux.
[0070]
  Thereafter, the plunger 4 returns to the initial position by the inertia in the direction of the initial position and the return force of the return spring 10, and the stopper 13 attached to the output shaft 5 collides with the bearing holder 7, as shown in FIG. 14 (d). Thus, the plunger 4 stops at the initial position.
[0071]
  The above operations are summarized as shown in FIG. Here, FIG. 15A shows the change with time of the displacement with respect to the initial position of the plunger 4, and FIG. 15B shows the change with time of the displacement with respect to the initial position of the yoke block.
[0072]
  By the way, since the point at which the launching member 9 collides with the game ball is when the plunger 4 is accelerated, if the yoke block moves due to the reaction during the acceleration of the plunger 4, the speed of the plunger 4 with respect to the game ball is reduced (the launching member 9). The collision speed of the game ball will be reduced), and the flight distance of the play ball will be reduced.
[0073]
  On the other hand, when the plunger 4 is decelerated, since the launching member 9 collides with the game ball and the game ball is fired, the movement of the yoke block is independent of the flight distance of the game ball. Since the plunger 4 is decelerated and reversed by the suction force in the direction opposite to the traveling direction of 4, the reaction force applied to the yoke block is larger than that during acceleration, so the buffer member 16 needs to be displaced greatly.
[0074]
  From the above, the hardness of each buffer member 16, 16 is reduced by reducing the hardness of the buffer member 16 on the side close to the launching member 9, thereby sufficiently displacing the yoke block to absorb vibration and impact, and launching It is desirable to increase the hardness of the buffer member 16 on the side far from the member 9 so as to reduce the displacement of the yoke block so as not to decrease the flight distance of the play ball.
[0075]
  ButOf this reference exampleIn the game board using the game ball launching device, vibration and impact sound transmitted from the yoke block to the game board can be reduced, and it is possible to provide a player with a comfortable game for a long time.
[0076]
  Further, unlike the conventional example 3, it is not necessary to provide the buffer members 47 and 48, the mounting frame 50 and the like separately from the solenoid, and the impact can be absorbed only by the solenoid body A, so that the number of parts and the assembly cost can be reduced. In addition, the accuracy of the mounting position of the game ball launcher with respect to the game board can be improved, and the factors causing variation in the flight distance of the game ball can be reduced.
[0077]
  (Reference Example 4)
  Of this reference exampleBasic configurationExample 316 to 18, the guide pipe block including the guide pipe 8, the bearings 6 and 6, and the bearing holders 7 and 7 is movable in a direction parallel to the axial direction of the output shaft 5. There is a feature in the point.
[0078]
  In this reference exampleThe base end portions of the narrow widths of the bearing holders 7 and 7 are slidable with respect to the holes of the housing 20 through which the base end portions are inserted. Here, a clearance is provided between the outer diameter of the base end portion of each bearing holder 7 and 7 and the inner diameter of the hole of the housing 20 so that the bearing holders 7 and 7 can slide in the axial direction. The pipe block is movable.
[0079]
  Also,In this reference exampleIn order to position the guide pipe block in the housing 20, a cushioning material 16a made of an elastic material such as rubber is disposed between the housing 20 and the bearing holders 7 and 7, respectively. Here, the cushioning material 16a has a disk shape having an opening in the center portion.Reference Example 3It is formed integrally with the buffer member 16 described in the above.
[0080]
  That is, the buffer member 16 has both a function of positioning the yoke block and restricting movement and a function of positioning the guide pipe block and restricting movement. There is no functional problem even if the cushioning member 16 and the cushioning material 16a are separated.In this reference exampleSince the shock-absorbing member 16 and the shock-absorbing material 16a are integrally formed, the number of parts can be reduced as compared with the case where they are separately formed, and the assemblability is improved and the cost is reduced.
[0081]
  Note that the shape and hardness of the cushioning material 16a reduce the occurrence of harmful vibration and collision noise to the game board when the guide pipe block receives an impact from the stopper 13 when the plunger 4 is returned to the initial position. What is necessary is just to set so that the guide pipe block can be displaced as much as necessary. The buffer material 16a may be any material that can effectively move the guide pipe block, and may be a coil spring, for example.
[0082]
  next,Of this reference exampleThe operation of the game ball launcher will be described.
[0083]
  When the coil 1 is not energized, the plunger 4 is in the predetermined initial position shown in FIG. 19D by the spring force of the return spring 10, and when the coil 1 is energized with a predetermined exciting current, the yoke 3 and the plunger 4 The plunger 4 is attracted by the yoke 3a and moves to the left in FIG. 19 against the spring force of the return spring 10 as shown in FIG. 19A (accelerates). At this time, a reaction force is generated in the yoke block in the direction opposite to the direction in which the plunger 4 moves. However, the yoke block moves in the direction opposite to the direction in which the plunger 4 moves, and the buffer member 16 is deformed to buffer. Since the movement is restricted by the member 16, the reaction force to the yoke block is absorbed, and the vibration and impact transmitted to the housing 20 and the game board are alleviated.
[0084]
  At a position near the end of the acceleration operation, the launching member 9 collides with a game ball set in advance at a predetermined position on the game board, and the game ball is launched. In addition, the arrow shown with the dashed-dotted line in Fig.19 (a) has shown the flow of magnetic flux.
[0085]
  After that, as shown in FIG. 19B, when the rear end of the plunger 4 (the end far from the launching member 9) passes through the insertion hole of the yoke 3b, the rear end of the plunger 4 and the yoke 3 A gap is formed between them, and the plunger 4 is decelerated due to the suction force. As a result, the direction in which the plunger 4 moves in the opposite direction (that is, the direction in which the plunger 4 returns to the initial position) is changed. During this deceleration, a suction force acts between the yoke block and the rear end of the plunger 4, and the yoke block is pulled by the plunger 4, so that a force in the same direction as the plunger 4 moves is applied, and the yoke block moves. Since the movement is restricted by the elastic deformation of the buffer member 16 on the side close to the punching member 9, it is possible to alleviate the impact transmitted to the yoke block from being transmitted to the housing 20 and the game board. In addition, the arrow shown with the dashed-dotted line in FIG.19 (b) has shown the flow of magnetic flux.
[0086]
  While the plunger 4 is reversed and returned to the initial position, a gap is formed between the front end of the plunger 4 (the end close to the launching member 9) and the yoke 3a as shown in FIG. Since a suction force is generated, the plunger 4 returns to the initial position while decelerating. In addition, the arrow shown with the dashed-dotted line in FIG.19 (c) has shown the flow of magnetic flux.
[0087]
  Thereafter, the plunger 4 returns to the initial position by the inertia toward the initial position and the return force of the return spring 10, and the stopper 13 attached to the output shaft 5 collides with the bearing holder 7. Then, due to the impact applied to the bearing holder 7, the guide pipe block is displaced to the right side in the figure as shown in FIG. 19 (d), the guide pipe block is displaced and the cushioning material 16a on the right side in the figure is also displaced. Is compressed and deformed, it is possible to suppress the impact accompanying the movement of the plunger 4 from being transmitted to the game board. Thereafter, the plunger 4 stops at the initial position.
[0088]
  The above operations are summarized as shown in FIG. Here, FIG. 20 (a) shows the time change of the displacement with respect to the initial position of the plunger 4, FIG. 20 (b) shows the time change of the displacement with respect to the initial position of the yoke block, and FIG. 20 (c) shows the guide pipe block. The time change of the displacement with respect to the initial position of is shown.
[0089]
  (Reference Example 5)
  Of this reference exampleBasic configurationIs Reference Example 121. As shown in FIG. 21, the only difference is that the outer shape of the stopper 13 is circular and a rotation stop member 13b ′ made of an elastic body is press-fitted into the output shaft 5 separately from the stopper 13. is there. In addition,In this reference exampleIs the shape of the anti-rotation member 13b 'Example 1The rotation stop member 13 b ′ slides on the inner surface of the guide groove 24 a of the guide portion 24 of the housing 20, thereby restricting the rotation of the output shaft 5 and the plunger 4.
[0090]
  (Embodiment1)
  Basic configuration of this embodimentIs Reference Example 422 to 24, the coil bobbin 2 is cylindrical and has a coil 1 wound around it and has flanges 2a at both ends, a yoke 3a that houses the coil bobbin 2, and a yoke A yoke 3b combined with the yoke 3a so as to cover the opening surface of 3a, a guide pipe 8 inserted into the through hole 2c of the coil bobbin 2, and a plunger which is inserted into the guide pipe 8 and reciprocates linearly between two specified positions. 4 and an output shaft 5 for firing a game ball set in advance at a predetermined position of the game board in the vicinity of one of the two positions in cooperation with the plunger 4 in response to the excitation of the coil 1; The return spring 10 is a coil spring that returns the plunger 4 to the initial position, which is the other of the two positions, and both ends of the output shaft 5 are inserted, and the output shaft 5 is slid. It has two bearing 6a for supporting, solenoid body A comprising a 6b to, comprises a housing 20 for mounting in accordance with the shape of the mounting portion of the game board while accommodating the solenoid body A. In additionReference Example 4The same reference numerals are given to the same constituent elements as in FIG.
[0091]
  The guide pipe 8 is inserted into the through hole 2c of the coil bobbin 2, and the wide portions 67a and 67b of the bearings 6a and 6b are fitted to both ends thereof. Each bearing 6a, 6b has a narrow base end portion 66a, 66b supported by the housing 20. Here, a pair of concave portions 28 and 29 for positioning and holding the base end portions 66a and 66b of the bearings 6a and 6b are formed in the divided bodies 20a and 20b constituting the housing 20 when they are combined with each other. . Therefore, the housing 20 can be positioned with the guide pipe block composed of the bearings 6a and 6b and the guide pipe 8 by combining the divided bodies 20a and 20b. The housing 20 is provided with projecting portions 25 projecting from both end portions of the housing main body 27, and bearings 6 a and 6 b are disposed in the vicinity of the center of the distal end portion of each projecting portion 25. .
[0092]
  The output shaft 5 penetrates the plunger 4 and is integrated with the plunger 4, and both end portions thereof are supported by the bearings 6 a and 6 b and protrude from the housing 20. Here, the plunger 4 moves back and forth linearly, for example, at a frequency of 100 times per minute by controlling energization to the coil 1. Further, a launching member 9 made of an elastic body that collides with the play ball when the output shaft 5 moves is attached to one end of the output shaft 5. Further, a disc-shaped plunger stopper 43 made of an elastic material such as rubber is attached to the output shaft 5 in order to prevent the plunger 4 from directly colliding with the bearing 6b. In addition, the stopper 43 for plungers has the hole 43a in which the output shaft 5 is penetrated formed in the center part. Here, the plunger stopper 43 moves together with the plunger 4.
[0093]
  The return spring 10 is held between a spring guide 18 fixed to the plunger 4 and a bearing 6 a on the side close to the launching member 9. Here, the plunger 4 is press-fitted in which a plunger press-fitting portion 18 a provided in the spring guide 18 is press-fitted between the outer end surface of the output shaft 5 on one end side in the axial direction (side closer to the launching member 9). A portion 4b (see FIG. 24) is formed, and the spring guide 18 is fixed by press-fitting the plunger press-fit portion 18a into the press-fit portion 4b.
[0094]
  Also in this embodiment, the coil bobbin 2 is movable on the outer peripheral surface of the guide pipe 8 integrally with the yokes 3a and 3b. That is, the yoke block is movable on the outer peripheral surface of the guide pipe 8. Here, in this embodiment, the cylindrical buffer member 16 made of an elastic body such as rubber is inserted through the guide pipe 8 in the center so that the yoke block does not collide with the inner surface of the housing 20 in the moving direction. A disk-shaped buffer member 36 made of an elastic body in which holes are formed is externally mounted on the guide pipe 8. The buffer member 16 is disposed so that one end in the axial direction protrudes into the internal space of the housing main body 27 of the housing 20, and the buffer member 36 is disposed so as to contact the inner surface of the housing main body 27. Therefore, the movement range of the yoke block is restricted by the buffer members 16 and 36, and the yoke block can be prevented from directly colliding with the inner surface of the housing body 27 in the movement direction.
[0095]
  In this embodiment, the guide pipe block including the guide pipe 8 and the bearings 6 a and 6 b is movable in a direction parallel to the axial direction of the output shaft 5. In short, in the present embodiment, the narrow base end portions 66a and 66b of the bearings 6a and 6b are slidable with respect to the holes of the housing 20 through which the base end portions 66a and 66b are inserted. In the present embodiment, for positioning the guide pipe block in the housing 20, a cushioning material 16a formed integrally with the cushioning member 16 is disposed between the housing 20 and the wide portion 67a of the bearing 6a. It is.
[0096]
  By the way, in this embodiment, the cylindrical weight 19 (refer FIG. 25) for adding mass to a guide pipe block is armored to one end part by which the bearing 6b is fitted in the guide pipe 8. The weight 19 is stored in the protruding portion 25. As the weight 19, a material having a large specific gravity such as metal is used.That's fine.
[0097]
  A cylindrical shock-absorbing member 46 (see FIG. 26) made of an elastic body such as rubber that restricts the moving range of the weight 19 is externally mounted on the base end portion 66b of the bearing 6b. Here, the buffer member 46 is disposed between the weight 19 and the inner surface of the housing 20 in the axial direction of the output shaft 5. Further, as shown in FIG. 26, a projecting piece 46a projecting inwardly protrudes from one end of the buffer member 46 in the axial direction, while a wide portion is formed at the base end 66b of the bearing 6b. A groove 68b into which the protruding piece 46a is fitted is formed at a position close to 67b. The groove 68b is formed along the circumferential direction on the outer peripheral surface of the base end portion 66b. Therefore, the buffer member 46 can be supported by sandwiching the guide pipe block with the above-described buffer member 16 by fitting the protruding piece 46a into the groove 68b of the bearing 6b. Further, a built-in piece 19 a (see FIG. 25) that protrudes inward from the inner peripheral surface protrudes from one end side in the axial direction of the weight 19, and this built-in piece 19 a is connected to the output shaft 5. It is sandwiched between the wide portion 67b of the bearing 6b and the protruding piece 46a of the buffer member 46 in the axial direction. Accordingly, the protruding piece 46a of the buffer member 46 is inserted into the groove 68b of the base end portion 66b of the bearing 6b in a state where the weight 19 is sheathed on the guide pipe 8 and the assembled piece 19a is brought into contact with the wide portion 67b of the bearing 6b. By fitting, the weight 19 is integrated into the guide pipe block.
[0098]
  Next, the operation of the game ball launcher of this embodiment will be described.

  When the coil 1 is not energized, the plunger 4 is in the predetermined initial position shown in FIG. 22B by the spring force of the return spring 10, and when a predetermined exciting current is applied to the coil 1, the yoke 3a and the plunger 4 are energized. The plunger 4 is attracted by the yoke 3a and moves to the left in FIG. 27 against the spring force of the return spring 10 (acceleration operation) as shown in FIG. At this time, a reaction force is generated in the yoke block in the direction opposite to the direction in which the plunger 4 moves. However, the yoke block moves in the direction opposite to the direction in which the plunger 4 moves, and the buffer member 36 is deformed to cushion. Since the movement is restricted by the member 36, the reaction force to the yoke block is absorbed, and the vibration and impact transmitted to the housing 20 and the game board are alleviated.
[0100]
  At a position near the end of the acceleration operation, the launching member 9 collides with a game ball set in advance at a predetermined position on the game board, and the game ball is launched.
[0101]
  Thereafter, as shown in FIG. 27 (b), when the rear end of the plunger 4 (the end far from the launching member 9) passes through the insertion hole of the yoke 3 b, the rear end of the plunger 4 and the yoke 3 A gap is formed between them, and the plunger 4 is decelerated due to the suction force. As a result, the direction in which the plunger 4 moves in the opposite direction (that is, the direction in which the plunger 4 returns to the initial position) is changed. During this deceleration, a suction force acts between the yoke block and the rear end of the plunger 4, and the yoke block is pulled by the plunger 4, so that a force in the same direction as the plunger 4 moves is applied, and the yoke block moves. Since the movement is restricted by the elastic deformation of the buffer member 16 on the side close to the punching member 9, it is possible to alleviate the impact transmitted to the yoke block from being transmitted to the housing 20 and the game board.
[0102]
  While the plunger 4 is reversed and returned to the initial position, a gap is formed between the front end of the plunger 4 (the end close to the launching member 9) and the yoke 3a as shown in FIG. Since a suction force is generated, the plunger 4 returns to the initial position while decelerating.
[0103]
  Thereafter, the plunger 4 returns to the initial position by the inertia in the direction of the initial position and the return force of the return spring 10, and the plunger stopper 43 that has been cooperating with the plunger 4 collides with the bearing 6 b. Then, due to the impact applied to the bearing 6b, the guide pipe block is displaced integrally with the weight 19 as shown in FIG. Here, the plunger 4 moves together with the guide pipe block, or moves to the right side in the figure at a lower speed than the guide pipe block after the collision. The guide pipe block and the weight 19 are displaced by the deformation of the buffer member 46. However, since the reaction force of the buffer member 46 is increased, the guide pipe block and the weight 19 are reversed. At this time, if the plunger 4 is displaced integrally with the guide pipe block, the plunger 4 is also reversed. On the other hand, when the plunger 4 is displaced independently, the bearing 6b of the guide pipe block and the plunger stopper 43 collide again when the guide pipe block starts to reverse.
[0104]
  After the guide pipe block is reversed, the guide pipe block returns to the initial position shown in FIG. On the other hand, after the guide pipe block returns to the initial position, the plunger 4 moves forward (left direction in FIG. 27) as it is, and becomes a rebound.
[0105]
  In this embodiment, the operation is performed as described above. However, when the plunger stopper 43 collides with the guide pipe block, the guide pipe block moves to the right in FIG. 27 and the buffer member 46 is compressed and deformed. By doing so, it is possible to suppress vibrations and shocks accompanying the movement of the plunger 4 from being transmitted to the game board.
[0106]
  The above operations are summarized as shown in FIG. FIG. 28 (a) shows the time change of the coil current, FIG. 28 (b) shows the time change of the displacement with respect to the initial position of the plunger block, and FIG. 28 (c) shows the displacement with respect to the initial position of the guide pipe block. The time change of is shown.
[0107]
  By the way, in order to suppress the vibration caused by the collision between the plunger 4 and the guide pipe block and the transmission of the shock to the game board, the hardness of the buffer member 46 should be as small as possible. However, as the hardness of the buffer member 46 is reduced, the guide pipe block is greatly displaced by the collision of the plunger 4 (plunger stopper 43), and the reaction causes the plunger 4 to rebound greatly.
[0108]
  As an example, the result of measuring the rebound amount of the plunger block by changing the mass of the weight 19 variously under the condition that the mass of the plunger block is 25 gf, the mass of the guide pipe block is 10 gf, and the hardness of the buffer member 46 is 30 °. It shows in FIG. Here, the horizontal axis of FIG. 29 represents the total mass of the guide pipe block and the weight, and the vertical axis represents the rebound amount of the plunger block. From FIG. 29, the relationship between the total mass of the guide pipe block that is the collision object and the weight 19 and the mass of the plunger block that is the collision object is
[Mass of plunger block] ≤ [Total mass of guide pipe block and weight]
In other words, it can be seen that the rebound of the plunger 4 can be further reduced by increasing the mass of the weight 19. On the other hand, in order to reduce the weight of the entire apparatus, the weight 19 should have a smaller mass. Therefore, in this embodiment, the weight 19 has a mass of 15 gf.
[0109]
  Note that the optimum value varies depending on conditions such as the mass of the plunger block, the speed at which the plunger block collides with the guide pipe block, the hardness of the buffer member 46, and the like.
[0110]
  Further, in the present embodiment, the weight 19 is configured as a separate part from the guide pipe block, and the built-in piece 19a provided on the weight 19 between the protruding piece 46a of the buffer member 46 and the wide portion 67b of the bearing 6b. However, the material of the bearing 6b may be made of a material having a large specific gravity, such as a metal, so that the mass of the guide pipe block itself may be increased. That is, you may make it give the function of the weight 19 to the bearing 6b. Further, it is desirable that the weight 19 and the guide pipe block be integrated, but a structure that is not integrated may be used.
[0111]
  In the present embodiment, the bearings 6a and 6b are respectively supported by the housing 20, and the guide pipe block composed of the bearings 6a and 6b and the guide pipe 8 moves relative to the housing 20 in a direction parallel to the moving direction of the output shaft 5. A weight 19 that cooperates with the guide pipe block is provided in the housing 20, and a buffer member 46 made of an elastic body that restricts the movement of the weight 19 is provided between the weight 19 and the housing 20. Therefore, by making the guide pipe block movable, vibrations and impact sounds transmitted from the guide pipe block to the game board 20 through the housing 20 can be reduced, and a comfortable game can be provided to the player for a long time. It becomes possible. Further, by providing the weight 19 that cooperates with the guide pipe block, even if the hardness of the buffer member 46 is reduced, the guide pipe block is rebound from the plunger 4 and the output shaft 5 or the guide pipe block is caused by the collision of the plunger 4. Displacement can be suppressed, and vibration and impact sound transmitted from the guide pipe block through the housing 20 to the game board can be further reduced by using a buffer member having a low hardness.
[0112]
  In addition, since the housing 20 does not need to form a magnetic path, there are few restrictions on the shape and material, and if the housing 20 is formed of resin, it can be easily molded and can cope with a complicated mounting structure. In addition, the cost and weight can be reduced. In short, as compared with the case where the yoke 3a is provided with a structure for mounting on a play board as in the conventional examples 1, 2, 4, 5, 6, it is possible to cope with a more complicated mounting structure. Further, if the housing 20 is made of a metal such as zinc, brass, or aluminum, the specific gravity is larger and the weight is increased as compared with the case where the housing 20 is made of resin, so that the impact transmitted from the solenoid body A to the game board is reduced. Can do.
[0113]
  Moreover, since the housing 20 can be processed by resin integral molding or die casting, and the bearings 6 and 6 can be fixed by the housing 20, the yoke 3a having an unstable shape as in the conventional examples 1, 2, 4, 5, and 6 is used. Compared to the case where the bearing 6 and the bearing holder 7 are fixed to the shaft 3b, the coaxiality of the two bearings 6a and 6b can be easily obtained, so that the output shaft 5 can be prevented from being twisted and the reciprocating linear movement operation can be achieved. The flying distance of the game ball can be stabilized stably.
[0114]
  Furthermore, in the case of a game ball launching device for each user that has the same characteristics required for the solenoid body A but differs only in the structure of the game board mounting portion, the structure of the solenoid body A can be made common to change the shape of only the housing 20. Since it can respond, cost reduction is attained.
[0115]
  (Embodiment2)
  Embodiment described above1Then, the shape of the buffer member 46 is formed in a cylindrical shape as shown in FIG. 30A. When the guide pipe block is displaced by the collision of the plunger stopper 43 with the bearing 6b, the buffer member 46 is compressed and deformed. However, when the displacement amount of the guide pipe block increases, the intermediate portion may be deformed into an extremely bent shape as shown in FIG. In the intermediate portion of the buffer member 46 bent in this way, the outer peripheral surface is stretched and the inner peripheral surface is in a compressed state. By the way, the embodiment1In this case, an elastic body such as rubber is used as the buffer member 46. However, although the rubber is less likely to cause a problem when it is stretched, friction occurs when it is compressed while being bent, and wear occurs when it is repeated. To do. Therefore, when the buffer member 46 has an extremely bent middle portion as shown in FIG. 30B, wear proceeds on the inner peripheral surface side of the middle portion of the buffer member 46, and the wear portion becomes a trigger. It is also conceivable that a crack K occurs and the shock-absorbing member 46 breaks at once, or a malfunction as a solenoid for firing a play ball occurs.
[0116]
  The basic configuration of this embodiment is the embodiment.1As shown in FIG. 31 (a), a gently hump-like protruding portion 46b is provided on the outer peripheral surface side at the intermediate portion of the buffer member 46 (that is, the portion that is bent during compression deformation). There is a feature in that. The other configurations are the embodiments.1Since it is the same as that, illustration and description are omitted.
[0117]
  In the present embodiment, since the protruding portion 46b is formed in advance in the intermediate portion of the buffer member 46, when the buffer member 46 is compressed and deformed, the protruding portion 46b and the portions on both sides thereof are bent. Even if the amount of displacement of the guide pipe block is the same as in FIG. 30B, the guide pipe block bends gently as shown in FIG. 31B compared to FIG. In short, in this embodiment, the buffer member 46 is not bent intensively, and local wear is less likely to occur.
[0118]
  The basic operation of this embodiment is the same as that of the embodiment.1However, when the buffer member 46 is deformed during operation, the reaction force of the buffer member 46 increases and the inertial force of the guide pipe block decreases, and the reaction force of the buffer member 46 and the guide pipe are reduced. The guide pipe block is displaced until the inertial force of the block becomes equal, and then the moving direction of the guide pipe block is reversed to the original direction and returned to the initial position.
[0119]
  Thus, in the present embodiment, local wear at the time of compression deformation of the buffer member 46 can be suppressed at low cost, the life can be extended, and the local at the time of compression deformation of the buffer member 46 can be achieved. Since the general wear can be suppressed, the amount of compressive deformation of the buffer member 46 can be increased and the amount of displacement of the guide pipe block can be increased as compared with the case without the protruding portion 46b. Vibration and impact sound transmitted from the pipe block to the play board through the housing 20 can be further reduced.
[0120]
  By the way, in the example shown in FIG. 31 (a), the protruding portion 46b has a partially protruding shape. However, as shown in FIG. 32, the thickness gradually decreases from the center toward both ends in the axial direction. The protruding portion 46b may be formed.
[0121]
  Further, the protruding portion 46b may be provided on the inner peripheral surface side of the buffer member 46, or may be provided on both the outer peripheral surface and the inner peripheral surface. Here, the shape of the protruding portion 46b, the material, hardness, dimensions, etc. of the buffer member 46 may be appropriately set according to conditions such as the speed and mass of the plunger 4, the life required for the solenoid, and environmental conditions.
[0122]
  In short, by providing a gentle projecting portion 46b on at least one of the outer peripheral surface and the inner peripheral surface at a portion that bends during compression deformation of the buffer member 46, local wear during compression deformation of the buffer member 46 can be reduced. In addition, it is possible to increase the life of the buffer member 46 and to suppress local wear during compression deformation of the buffer member 46, so that the buffer member can be compared with the case where there is no projecting portion 46b. The amount of compression deformation of 46 can be increased, and the amount of displacement of the guide pipe block can be increased, so that vibration and impact sound transmitted from the guide pipe block to the play board through the housing 20 can be further reduced. It is.
[0123]
  (Embodiment3)
  By the way, the embodiment1Or embodiment2In the game ball launching apparatus having the configuration, when the output shaft 5 rotates while continuously playing the game balls, the contact state between the launching member 9 attached to the tip of the output shaft 5 and the game balls gradually changes. However, since there may be variations in the flight distance of the play balls, it is desirable that the plunger block in the solenoid that reciprocates linearly does not have a rotational force during operation. In some cases, a rotational force may be generated on the output shaft 5 due to a positional shift when the play ball and the launching member 9 collide with each other.
[0124]
  The basic configuration of this embodiment is the embodiment.1The protrusion 10d as shown in FIG. 35 or FIG. 36 that protrudes in the direction of the winding axis is provided at the end of the end wound portion at both ends of the return spring 10 made of a coil spring, as shown in FIG. As described above, a rotation-preventing groove 69a having a V-shaped cross section is provided radially on the contact surface 65a of the bearing 6a with the end winding portion of the return spring 10 so that the protrusion 10d can enter and prevent the return spring 10 from rotating. As shown in FIG. 34, the protrusion 10d enters the contact surface 18c of the spring guide 18 with the end winding portion of the return spring 10, and the rotation prevention groove has a V-shaped cross section so that the return spring 10 can be prevented from rotating. It is characterized in that 18d is provided radially. Here, the protrusion 10d in FIG. 35 is a burr when the wire constituting the return spring 10 is cut, and the protrusion 10d in FIG. 36 is formed by bending the end of the wire. The other configurations are the embodiments.1Or embodiment2Since it is the same as that, illustration and description are omitted.
[0125]
  Since the initial load is applied to the return spring 10 at the time of incorporation, the projecting portion 10d of the end winding portion of the return spring 10 is pressed against the contact surface of the bearing 6a.
[0126]
  Therefore, in the present embodiment, when a rotational force is applied to the output shaft 5, the spring guide 18 in which the plunger press-fitting portion 18a is press-fitted into the press-fitted portion 4b of the plunger 4 rotates. Then, one protrusion 10d of the return spring 10 enters the rotation prevention groove 18d while being pressed against the contact surface 18c of the spring guide 18. Then, the return spring 10 rotates, and the other protrusion 10d of the return spring 10 similarly enters the rotation prevention groove 69a provided on the contact surface 65a of the bearing 6a.
[0127]
  For example, FIGS. 35 (a) and 36 (a) show a state in which the protruding portion 10d of the return spring 10 has entered the rotation prevention groove 69a of the bearing 6a. In this state, for example, as shown in FIGS. 35 (b) and 36 (b), when a rotational force in the direction of arrow F1 is applied to the end portion of the end portion of the return spring 10, the protrusion 10d is prevented from rotating. The rotation of the return spring 10 is restricted by resistance when trying to escape from the state of entering the groove 69a. Conversely, as shown in FIGS. 35 (c) and 36 (c), when a rotational force in the direction of arrow F2 is applied to the end of the end of the return spring 10, the protruding portion 10d is a slope of the rotation preventing groove 69a. The rotation of the return spring 10 is restricted. Therefore, during the operation of the plunger 4, the protruding portion 10 d of the return spring 10 gets over the rotation prevention groove 69 a and rotates unless the end winding portion of the return spring 10 dances due to resonance or the like. Absent.
[0128]
  When the output shaft 5 is rotated by applying a large force by hand when the solenoid is not operating, the protruding portion 10d gets over the rotation prevention groove 69a, so the output shaft 5 rotates. If it does not rotate when the is operating, there will be no effect on the variation in the flight distance.
[0129]
  Thus, in the present embodiment, the projecting portions 10d and 10d projecting in the winding axis direction are provided at the ends of the end winding portions at both ends of the return spring 10 made of a coil spring, and the return springs of the bearing 6a and the spring guide 18 respectively. Since the protrusions 10d enter the contact surfaces 65a and 18c with the 10 end windings and the rotation preventing grooves 69a and 19d are provided in a radial manner to prevent the return spring 10 from rotating, the plungers are provided as in the conventional example. The magnetic path cross-sectional area does not decrease and the speed of the plunger 4 does not decrease due to sliding friction as in the case where the groove 4a is formed in the groove 4 to prevent the plunger 4 from rotating. The rotation of the output shaft 5 can be regulated at a low cost without giving any friction, and there is a part that wears like the case where the groove 4a is formed in the plunger 4 to prevent the plunger 4 from rotating. Because never Jill, it is possible to extend the life of. Further, the protruding portion 10d provided on the return spring 10 may be formed by using the burr at the time of cutting the wire as it is, or may be formed by bending the end portion, and the bearing 6a and the spring guide 18 respectively. The anti-rotation grooves 69a and 18d provided in FIG. 5 do not require special processing if the bearing 6a and the spring guide 18 are molded parts, and can prevent the return spring 10 from rotating at low cost.
[0130]
  In the present embodiment, the cross-sectional shape of the rotation preventing grooves 69a and 18d is V-shaped, but is not limited to the V-shape, and may be, for example, a square cross-sectional shape. Further, the size of the burr and the bending as the protruding portion 10d may be designed so that the return spring 10 does not rotate due to the rotational force generated when the solenoid operates. Further, the set load of the return spring 10 needs to be set so as not to be too light. That is, it is necessary to set the load so that the end winding portion does not lift up due to vibration caused by the operation of the plunger 4 and the plunger 4 does not rotate during the continuous operation of the solenoid.
[0131]
  (Embodiment4)
  The basic configuration of this embodiment is the embodiment.139. As shown in FIG. 39, projecting portions 10d projecting inward in the radial direction are provided at the ends of the end winding portions at both ends of the return spring 10 made of a coil spring, as shown in FIGS. As shown in the figure, a rotation prevention groove 69a is provided around the outer peripheral surface of the portion of the bearing 6a that protrudes from the contact surface 65a of the return spring 10 with respect to the end winding portion so that the rotation of the return spring 10 can be prevented. 38. As shown in FIG. 38, the protruding portion 10d is inserted into the outer peripheral surface of the portion of the spring guide 18 that protrudes from the contact surface 18c with the end turn portion of the returning spring 10, as shown in FIG. The anti-rotation groove 18d that can prevent the rotation of the rotation angle 10d is provided apart from each other in the circumferential direction.
[0132]
  Thus, in the present embodiment, projecting portions 10d and 10d projecting inward in the radial direction are provided at the ends of the end winding portions at both ends of the return spring 10 made of a coil spring, and the return of each of the bearing 6a and the spring guide 18 is provided. Anti-rotation grooves 69a and 18d that allow the protrusions 10d and 10 to enter and prevent the return spring 10 from rotating on the outer peripheral surface of the portion protruding from the contact surfaces 65a and 18c with the end winding portion of the spring 10 in the circumferential direction. Since the grooves 4a are formed in the plunger 4 to prevent the rotation of the plunger 4 as in the conventional example, the magnetic path cross-sectional area is reduced or the speed of the plunger 4 is slid. The rotation of the output shaft 5 can be regulated at a low cost without affecting the flying distance of the play ball, and the groove 4a is formed in the plunger 4. Because it does not cause parts to wear as in the case to prevent rotation of the plunger 4, it is possible to increase the life of. Further, the protruding portions 10d and 10d provided on the return spring 10 may be formed by using the burr at the time of cutting the wire as it is, or may be formed by bending the end portion, and the bearing 6a and the spring guide. The anti-rotation grooves 69a and 18d provided in the respective 18 do not require special processing if the bearing 6a and the spring guide 18 are molded parts, and can prevent the return spring 10 from rotating at a low cost.
[0133]
  By the way, in this embodiment, even if a rotational force is applied to the plunger 4, the protrusions 10 d and 10 d that have entered the rotation prevention grooves 69 a and 18 d are caught by the rotation prevention grooves 69 a and 18 d to become resistance and the rotation is restricted. . Further, when a strong rotational force such as turning by hand is applied, the protruding portion 10d is detached from the rotation preventing grooves 69a and 18d that have been in, but enters the nearby rotation preventing grooves 69a and 18d when the rotational force decreases, Rotation is restricted at that location.
[0134]
  Embodiment3, 4In both cases, it is not necessary to insert the protruding portion 10d of the return spring 10 into a specific groove or hole, so that there is no need to worry about the direction during assembly, and the assembly is improved.
[0135]
【The invention's effect】
  ContractClaim1The present invention is a cylindrical bobbin that is wound with a coil and has flanges at both ends, a yoke that houses the coil bobbin, and a reciprocating linear movement between two specified positions inserted into a through hole of the coil bobbin.

The solenoid body is housed in the internal space, and is provided with a housing that is fitted in accordance with the shape of the mounting area of the game board. The housing is attached using screws to the mounting area of the game board. In the case of a game ball launcher for each user, the characteristics required for the solenoid body are the same and only the structure of the game board attachment part is different, so that the structure of the solenoid body is shared. Therefore, it is possible to cope with the change by changing only the housing, and the cost can be reduced. Moreover, since the housing does not need to form a magnetic path, there are few restrictions on the shape and material, and if the housing is formed of resin, it can be used for a complicated mounting structure, and can be reduced in cost and weight. Can be achieved. Further, if the housing is made of a metal such as zinc, brass, or aluminum, the specific gravity is larger and the weight is increased as compared with the case of resin, so that the impact transmitted from the solenoid body to the game board can be reduced. Further, since the housing is provided, it is not necessary to process the yoke in accordance with the shape of the attachment portion of the play board as in the conventional example, so that the cost required for processing the yoke and the assembling cost can be reduced.
[0136]
  In addition,Claim1DepartureIn the morning,Inserted into the through hole of the ilbobineRepSince it has a cylindrical guide pipe into which the ranger is inserted, and each bearing is built in at both ends of the guide pipe, the coaxiality of the two bearings is determined only by the precision of the parts of the bearing holder and the guide pipe. Since the high coaxiality of the bearings can be obtained, the output shaft is not twisted due to the deviation of the coaxiality of the two bearings, and the flying distance of the play ball can be stabilized at low cost.
[0137]
  In addition,Claim1DepartureIn the morning,A yoke block composed of a coil and a yoke is movable relative to the housing in a direction parallel to the direction of movement of the output shaft, and a buffer member made of an elastic body that restricts movement of the yoke block is provided on both sides of the direction of movement of the yoke block. Because it is provided, the yoke block can be moved and its movement is regulated by the buffer member, so vibration and impact sound generated in the yoke and transmitted to the game board as the plunger reciprocates linearly moves can be reduced at low cost. And it is possible to provide a player with a comfortable game for a long time..
[0138]
  In addition,Issue of claim 1In the morning, eachEach bearing is supported by the housing, and a guide pipe block composed of the bearing and the guide pipe is movable with respect to the housing in a direction parallel to the moving direction of the output shaft, and there is a weight that cooperates with the guide pipe block in the housing. A buffer member made of an elastic body that is provided on the other side of the two positions and restricts the movement of the weight is provided between the weight in the moving direction and the housing, so that the guide pipe block can be moved. As a result, vibration and impact sound transmitted from the guide pipe block to the game board through the housing can be reduced, and it becomes possible to provide a player with a comfortable game for a long time. By providing a weight that moves together with the block, the plunger can be Displacement of the guide pipe block due to rebound of the plunger block consisting of the shaft and collision of the plunger can be suppressed, and by using a low hardness member as the buffer member, it is transmitted from the guide pipe block to the game board through the case. There is an effect that vibration and impact sound can be further reduced.
[0139]
  Claim2The invention of claim1In the invention, the shock-absorbing member made of an elastic body that restricts the movement of the weight is arranged in a cylindrical shape so that the output shaft and the axial direction coincide with each other and bends when the shock-absorbing member is compressed and deformed Since at least one of the outer peripheral surface and the inner peripheral surface is provided with a gentle projecting portion, the projecting portion has a smooth projecting portion on at least one of the outer peripheral surface and the inner peripheral surface at a portion that is bent during compression deformation of the buffer member. By providing this, local wear during compression deformation of the buffer member can be suppressed at a low cost, the life can be extended, and local wear during compression deformation of the buffer member can be suppressed. Since the amount of compressive deformation of the buffer member can be increased and the amount of displacement of the guide pipe block can be increased compared to the case where there is no protrusion, the guide pipe block Vibration transmitted to game machine along the housing, there is an effect that it is possible to further reduce impact noise.
