It is provided vertically. For this reason, it may be difficult for a player having a different physique to operate.
[0003]
Therefore, conventionally, in order to improve the operability of the operation handle, an operation handle in which the operation handle is movable in one direction (vertical direction) with respect to the front surface of the front frame has been invented and disclosed in Japanese Patent Laid-Open No. 3-128076. Yes.
[0004]
The operation handle disclosed in Japanese Patent Application Laid-Open No. 3-128076 is inserted from a side of the fixing member and a cylindrical fixing member that is provided with an elastic force adjusting mechanism and is fixed to the front surface of the pachinko machine. A connection pin, a handle connected to the front end of the fixing member via the connection pin and rotatable up and down around the connection pin, and an operation lever incorporated rotatably in the circumferential direction of the handle; Have. The operation handle has a rotating shaft that is inserted into the fixing member and the handle, one end is connected to the operation lever, and the other end is connected to the elastic force adjusting mechanism through a universal joint. The striking force can be adjusted by being transmitted to the elastic force adjusting mechanism provided integrally with the fixing member via the rotating shaft provided with the universal joint.
[0005]
Around the connecting pin, clutch teeth are provided on each member so as to fix the handle to the fixing member, and on the handle side so that the clutch teeth facing each other are always engaged. And a spring for pressing the clutch tooth against the clutch tooth on the fixed member side. Then, the clutch teeth on the handle side mesh with the clutch teeth provided on the fixed member side, and the handle is fixed to the fixed member at a predetermined angle.
[0006]
In order to change the angle of the handle, the handle is rotated up and down by a force that prevails over the spring that biases the clutch teeth, and is changed to a predetermined angle.

[0027]
As shown in FIG. 2, the bullet launching device 50 to be operated by the operation handle 60 is fixed to the front frame rear surface side 3b via a base plate 51 that collects and holds the main components of the bullet launching device 50. Yes.
[0028]
The main components provided on the base plate 51 are a launch bar 52 which is provided in the approximate center of the base plate 51 and launches a ball into the game board 40, a main shaft 53 which rotatably supports the launch bar 52, and a ball launch. Examples include a spring 54 that urges the launch bar 52 in a direction (direction of arrow S in the figure), a cam 56 that pulls the launch bar 52 back to a predetermined position against the spring 54, and a link mechanism 56a. The cam 56 is attached to an electric motor 55 for rotating the cam 56.
[0029]
Then, as the rotation angle of the cam 56 increases, the launch bar 52 is gradually pulled in the direction of the arrow R in the figure, and at the same time the cam 56 reaches a predetermined rotation angle, the restraint of the launch bar 52 is released via the link mechanism 56a. The ball is ejected onto the game board 40 by the tension of the spring 54 connected to the launch bar 52.
[0030]
The tension of the spring 54 can be arbitrarily adjusted via a spring adjusting mechanism. The spring adjustment mechanism is provided on the spring take-up pulley 57 to which one end of the spring 54 is fixed, the wire take-up pulley 59 connected to the spring take-up pulley 57 via the wire 58, and the wire take-up pulley 59.

[0031]
When the operation handle 60 is rotated in the circumferential direction, the rotation is transmitted in the order of the striking force adjusting shaft 11 → the wire take-up pulley 59 → the wire 58 → the spring take-up pulley 57. The spring 54 is wound up by rotating in the direction of the arrow K in the figure in synchronization with the rotation operation. Then, the fixed end of the spring 54 moves in the direction of increasing the tension (in the direction of the arrow k in the figure), so that it is possible to launch with a stronger striking force. Hereinafter, the operation handle 60 connected to the bullet launching device 50 will be described in more detail with reference to FIGS.
[0032]
The operation handle 60 is attached via a bearing 61 that rotatably supports the operation handle 60 with respect to the front surface 3a of the front frame in all directions. The bearing portion 61 is formed by combining a plurality of synthetic resin members, and as shown in FIG. 4, a spherical body 62 (convex portion) serving as a pivot point of the operation handle 60 and the spherical body 62 are rotatably engaged. A fixing member 64 having a spherical recess 63 and fixed to the front surface 3a of the front frame. In addition, 62a and 64a in FIG. 4 are the dividing lines of each member.
[0033]
As shown in FIG. 7, a mortar-shaped opening 65 communicating with the concave portion 63 is formed on the surface portion of the fixing member 64 fixed in contact with the front surface 3a of the front frame. The hitting force adjusting shaft 11 is exposed in 65. Further, a rotation shaft insertion hole 66 continuously formed from the surface of the sphere 62 toward the opposite surface is formed on the surface of the sphere 62 facing the opening 65, and one end of the rotation shaft insertion hole 66 has the one end described above. A rotating shaft 67 connected to the striking force adjusting shaft 11 is inserted. A disc-shaped operation handle 60 is fixed to the other end of the rotating shaft 67. In the present embodiment, the rotating shaft 67 and the operation handle 60 are integrally manufactured as one member, but the members 60 and 67 can also be manufactured separately.
[0034]
A torsion coil spring 68 is fixed to one end side of the rotating shaft 67, and the rotating shaft 67 is connected to the striking force adjusting shaft 11 through the torsion coil spring 68. Further, a flexible tube 69 is fitted on the outer periphery of the torsion coil spring 68, and this tube 69 suppresses unnecessary deformation of the torsion coil spring 68 when the operation handle 60 is rotated.
[0035]
In the present embodiment, the torsion coil spring 68 is exemplified as the connecting member that connects the rotating shaft 67 and the striking force adjusting shaft 11. However, for example, a hard sponge formed in a columnar shape may be employed. Furthermore, you may connect using universal joints, such as a universal joint.
[0036]
As shown in FIG. 9, even when the rotation shaft 67 is rotated via the bearing portion 61, the rotation of the rotation shaft 67 is accurately transmitted to the batting force adjustment shaft 11 via the torsion coil spring 68. The The mortar-shaped opening 65 serves as a relief for avoiding interference between the rotating shaft 67 and the fixing member 64 when the rotating shaft 67 is inclined.
[0037]
In addition, an end surface 71 is formed on the surface of the sphere 62 with which the operation handle 60 comes into contact, and the operation handle 60 side in contact with the end surface 71 of the sphere 62 is also formed on the smooth surface 72. For this reason, the operation handle 60 is stably supported on the sphere 62, and when the operation handle 60 is operated, the smooth surface 72 of the operation handle 60 contacts the end surface 71 on the sphere 64 side and smoothly rotates the operation handle 60. Can be made.
[0038]
Thus, the operation handle 60 shown in the present embodiment is attached to the front frame front surface 3a via the bearing portion 61 that is rotatable in all directions with respect to the front frame front surface 3a. The operation handle 60 can be operated at an angle and a position.
[0039]
In addition to the above configuration, the operation handle 60 shown in the present embodiment further includes a fixing mechanism (fixing means) that fixes the operation handle 60 at a desired rotation angle. Hereinafter, this fixing mechanism will be described with reference to FIGS.
[0040]
First, the outline of the fixing mechanism will be described. A metal sleeve 80 that is slidably fitted to the rotating shaft 67 is provided, and the sleeve 80 is slid in the axial direction of the rotating shaft 67 and held by the bearing portion 61. The sphere 62 is press-fitted. The spherical body 62 is expanded by press-fitting the sleeve 80, and the surface of the expanded spherical body 62 is locked to the inner wall surface of the recess 63 of the fixing member 64. The angle and position of the operation handle 60 with respect to the front surface 3a of the front frame can be fixed at a desired position via the constrained sphere 62.
[0041]
The sleeve 80 that puts the spherical body 62 into a constrained state has a cylindrical shape formed of a rigid body such as metal, and an operation portion 83 is provided at one end of the sleeve 80. Further, a spherical protrusion 84 is provided at the other end of the sleeve 80 and is slidably fitted to the rotary shaft 67 so that the end portion side having the operation portion 83 becomes the operation handle 60 side. In the present embodiment, a plate-like operation unit 83 is simply employed, but the shape of the operation unit 83 is not limited to a plate shape.
[0042]
The operation handle 60 connected to the rotary shaft 67 is formed with a cut groove 85 in which the operation portion 83 of the sleeve 80 is accommodated on the smooth surface 72, and the operation portion 83 is accommodated in the cut groove 85. ing. That is, as shown in FIGS. 7 and 8, the operation portion 83 is accommodated in the kerf 85, and the operation unit 83 is operated in the kerf 85. For this reason, the operation part 83 does not get in the way and the stability of the operation handle 60 with respect to the end surface 71 of the sphere 62 is not impaired.
[0043]
On the other hand, the sphere 62 is provided with slits 86 that are radially cut from the front (game machine side) to the back (player side) (see FIGS. 4 and 10). A portion having low rigidity is locally formed in front of 62 (on the gaming machine side).
[0044]
Furthermore, a hollow portion 82 having a conical shape whose inner diameter decreases toward the front (the gaming machine side) is provided at a substantially intermediate point of the rotary shaft insertion hole 66 provided in the sphere 62. The entire length of the sleeve 80 is set so that the tip of the sleeve 80 protrudes into the portion 82. Since the sphere 62 is formed by two symmetrical members 62c and 62d as shown in FIG. 4, when the sleeve 80 is assembled into the sphere 62, the sleeve 80 is first fitted into one sphere 62c, Then, the sphere 62c incorporating the sleeve 80 and the other sphere 62d are joined.
[0045]
The vicinity of the opening (player side) of the rotary shaft insertion hole 66 into which the sleeve 80 is inserted is formed to have an inner diameter substantially equal to the outer diameter of the sleeve 80, and the sleeve 80 does not interfere with the rotary shaft 67. The rotary shaft 67 is inserted into the rotary shaft insertion hole 66 together with the rotary shaft 67. That is, the sleeve 80 corresponds to a guide for the rotation shaft 67, and the rotation shaft 67 is held by the sphere 62 via the sleeve 80. The sleeve 80 inserted into the rotation shaft insertion hole 66 is slidable with respect to the rotation shaft 67 as well as being slidable with respect to the rotation shaft insertion hole 66.
[0046]
When the operating portion 83 provided on the sleeve 80 is pushed forward (to the gaming machine side) in the kerf 85, only the sleeve 80 is moved forward (to the player side) with respect to the rotating shaft 67 and the sphere 62. It slides and the front-end | tip contacts the inner wall face of the cavity part 82 formed in the cone shape. Then, when the operation portion 83 is further pushed forward from there, as shown in FIGS. 9 and 11, the portion where the slit 86 is cut and the rigidity is lowered spreads outward and is pressed against the inner wall surface of the recess 63. Become. For this reason, the sphere 62 is locked to the inner wall surface of the recess 63. Therefore, the rotating shaft 67 and the operation handle 60 fixed to the rotating shaft 67 can be fixed at a predetermined inclination angle via the spherical body 62 constrained by the concave portion 63. FIG. 11 is a principle diagram when the sphere 62 spreads outward.
[0047]
Even when the sphere 62 expands and the bearing portion 61 is fixed, the sleeve 80 for expanding the sphere 62 is formed of a rigid body such as metal as described above. It is not crushed by the reaction force (restoring force) to return to the position, and the clearance between the rotary shaft 67 inserted into the sleeve 80 and the sleeve 80 is sufficiently secured. Therefore, even when the sleeve 80 is press-fitted, the rotation operation of the operation handle 60 is not hindered.
[0048]
The hollow portion 82 is provided with a sleeve holding groove 87 that engages with a spherical protrusion 84 provided at the tip of the sleeve 80 to hold the sleeve 80 at a predetermined position of the hollow portion 82. Here, the predetermined position indicates a position where the sphere 62 is appropriately spread outward and restrained. In the present embodiment, a sleeve holding groove 87 is formed at the front end (game machine side) of the cavity portion 82. The sleeve 80 is held in the hollow portion 82 by the sleeve holding groove 83 and is not pushed back by the restoring force of the sphere 62.
[0049]
Therefore, the restraint state of the sphere 62 can be maintained even after the operation unit 83 is operated. Further, when the operation unit 83 is operated, a moderate feeling of moderation is obtained through the operation unit 83, and the player can recognize that the bearing unit 61 is fixed. As described above, the operation handle 60 can be fixed in a stepless manner at a desired rotation angle and position, so that the operability of the operation handle 60 is further improved.
[0050]
The fixing mechanism for fixing the bearing portion 61 is not limited to the one in which the sphere 62 side is expanded to fix the bearing portion 61, but the bearing portion 61 is contracted by contracting the concave portion 63 side that rotatably holds the sphere 62. A fixing mechanism that can fix 61 may be used. Hereinafter, a preferred embodiment in which the concave portion 63 side is contracted to fix the bearing portion 61 will be described.
[0051]
<Embodiment 2>
First, an outline of a fixing mechanism for fixing the bearing portion 61 by contracting the concave portion 63 side will be described with reference to FIGS. The fixing mechanism shown in this embodiment is provided with a pressing lid 90 that fits on the opening 91 side of the concave portion 63 described above, and by screwing the pressing lid 90 into the concave portion 63, the concave portion 63 is contracted, and the inside of the concave portion 63. Squeezes the sphere 62 incorporated in the. Thereby, the sphere 62 is locked to the inner wall surface of the recess 63 and the sphere 62 is restrained.
[0052]
As shown in FIG. 13, the push lid 90 to be screwed in from the opening 91 side of the concave portion 63 has a spherical body support portion 96 formed in a bowl shape in which a male thread 93 is cut on the outer peripheral surface and the inner peripheral surface follows the surface of the sphere 62. And when this spherical body support part 96 is integrated in the recessed part 63, the collar part 94 is provided in the end surface used as the near side (player side).
[0053]
On the other hand, the recess 63 side into which the push lid 90 is screwed is also greatly opened on the opening 91 side so as to have the same inner diameter as the outer diameter of the push lid 90, and the side wall surface in the vicinity of the opening 91 has the above-described push lid 90. A female thread 95 that engages the male thread 93 is formed. Then, after the spherical body 62 is assembled in the recess 63, the push lid 90 is attached.
[0054]
And when fixing the bearing part 61, after adjusting the operation handle 60 to a favorite position, the collar part 94 of the push lid 90 is turned, and the push lid 90 is screwed in into the recessed part 63. As shown in FIG. Then, the inside of the concave portion 63 is gradually contracted from the opening 91 side, and the sphere 62 incorporated in the concave portion 63 is pressed and locked to the inner wall surface of the concave portion 63. Therefore, the bearing 61 is fixed, and the operation handle 60 is held at a predetermined rotation angle and position by the fixed bearing 61.
[0055]
As described above, in this embodiment, the operation handle can be fixed steplessly by expanding the sphere or contracting the recess, so that the operation can be performed at a fine angle according to the player's physique and preference. The handle can be fixed.
[0056]
In addition, the operation handle shown in the present embodiment has fewer components than the conventional operation handle that rotates in one direction as described above, and is very easy to assemble. For this reason, the labor and cost required for production can be greatly reduced.
[0057]
Note that the operation handle shown in the present embodiment is not limited to the above-described bullet ball game machine, and can of course be employed in various ball game machines capable of playing a game using a bullet ball. Furthermore, the bullet launching device to which the operation handle is connected is not limited to the above-described bullet launching device, and can correspond to a bullet launching device that launches a bullet with another mechanism. That is, the operation handle shown in this embodiment can be provided in a ball game machine having a ball launching device capable of adjusting the hitting force in conjunction with the rotation operation of the operation handle.
