The following Patent Documents 1 and 2 disclose hitting ball launching handles having the same structure as these.
Japanese Patent No. 2602185 Japanese Patent Laid-Open No. 2003-117099 (FIG. 5)

By the way, since the hitting ball launching handle of the pachinko gaming machine is operated by an unspecified number of people, it is desirable that the handle has a round shape that can be easily adapted to the player's hand and can be used by anyone without any discomfort.
However, in the conventional hitting ball launching handle, as shown in FIG. 11, the back side of the finger hooking projection c formed on the operation lever b is vertical even though the grip portion a is formed in a substantially spherical shape. As shown in FIG. 12, the back surface has a shape in which a cavity is opened, or as shown in FIG. There was a drawback that was difficult to adapt to fingers. Further, in the case where a portion d extending rearward as shown in FIG. 13 is formed, or in the case where a portion e extending forward is formed in the projection c as shown in FIG. Since e is separated from the outer peripheral surface of the grip portion a and a gap g is formed, the operability is rather impaired because there is a possibility that the skin of the finger is caught in the gap g when the operation lever b is rotated. There was also a possibility. Since these conventional control levers are integrally formed in an annular shape by a mold that is punched in the front-rear direction, a cavity opening on the back surface is inevitably formed in the protrusion c, and the above extension This is because it is difficult to mold the part d or e into a shape along the spherical surface of the grip part a because of the mold structure.
Further, as shown in FIG. 15, it is possible to form the upper surface of the protrusion c round, but there is a problem that it becomes difficult to see because the parting line f of the mold appears on the surface.
In order to solve such a problem, as shown in FIG. 16, it is conceivable to form the grip portion a in an aspherical shape. However, in this case, there is a problem that it is difficult to be familiar with the player's fingers. is there.

On the other hand, in the above-mentioned Patent Document 2 relating to the applicant's patent application, a configuration is shown in which the operating lever is divided into two parts and is formed into an annular shape by assembling both with a screw. However, the one disclosed in the same publication was not changed to the one formed by the die that was punched in the front-rear direction as described above, so that the player's fingers as in the conventional example shown in FIG. There was a drawback that was difficult to get familiar with.
SUMMARY OF THE INVENTION Accordingly, the present invention is intended to provide a hitting ball launching handle that can be easily adapted to a player's finger without forming a gap as described above in the operation lever or a cavity opened on the back surface.

For this purpose, the hitting ball launching handle of the pachinko gaming machine according to claim 1 is capable of rotating an annular operation lever for adjusting the hitting strength of the hitting ball on the outer periphery of the grip portion whose outer peripheral surface is formed in a substantially spherical shape. In the hitting ball launching handle of the provided pachinko gaming machine, the operation lever is formed by combining a substantially semi-annular upper molded body integrally formed with finger hooking projections on the outer peripheral portion and a substantially semi-annular lower molded body. When the upper molded body is plastic-molded, the finger-hooking projections are forwardly and without gaps from the outer peripheral portion of the upper molded body along the outer peripheral surface of the grip portion by die-cutting in the vertical direction. The lower surface is formed in an arc shape so as to extend rearward.
According to a second aspect of the present invention, in the ball striking ball launching handle, when the upper molded body is plastic-molded, the finger hooking protrusion is removed from the outer peripheral portion of the upper molded body by vertically releasing the upper molded body. The lower surface is formed in an arc shape so as to extend forward and rearward without any gap, and a cavity having an opening on the lower surface is formed inside the finger hooking projection.

  It is possible to provide a hitting ball launching handle having a shape that can easily be adapted to a player's finger and having excellent operability.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a hitting ball launching handle according to the present invention, and FIG. 2 is an exploded perspective view thereof. Reference numeral 1 denotes a handle base in which a hemispherical shell-like portion 1b is integrally formed at the tip of the cylindrical portion 1a. Reference numeral 2 denotes a rotation angle detector comprising a variable resistor provided in the handle base. The handle base is a pachinko game. Affixed to the front of the machine (not shown). Reference numeral 3 denotes a handle cap formed in a substantially hemispherical shell shape. The handle cap is fixed to the front surface of the handle base 1 with screws 4a to 4c with a rotatable annular operation lever 6 described later. The substantially spherical grip portion 5 is formed so as not to rotate. Reference numeral 3a denotes a spherical translucent cap that is integrally fitted to the tip of the handle cap.

  Thus, the operation lever 6 is formed in an annular shape by combining a substantially semi-circular plastic upper molded body 7 and a substantially semi-circular plastic lower molded body 8 and joining them with screws 9a and 9b. Is. Further, the upper molded body 7 is molded by a plastic injection molding die that is vertically cut, and a finger hooking projection 10 is integrally molded on the outer periphery thereof. The finger hooking protrusion 10 has a bottom surface formed in an arc shape so as to extend forward and rearward along the outer peripheral surface of the grip portion 5, and 3 on the upper surface with a gap corresponding to one finger. The chevron ridges 11a to 11c of the book are formed into a smooth curved surface, and a cavity 12 having an open bottom surface is formed inside the finger hooking projection 10. 13a and 13b are a pair of mounting ribs formed on the inner periphery of the upper molded body 7, and 14a and 14b are through holes formed in the ribs for inserting the screws 9a and 9b. The lower molded body 8 has an arc-shaped through-hole 15 on the inner periphery, a boss 16 is formed at the center, and a D-shaped mounting hole for inserting the shaft of the rotation angle detector 2 into the boss. 17 is formed. Reference numeral 18 denotes a winding spring that urges the operation lever 6 to rotate. One end of the winding spring is fastened in the handle base 1 with a screw 18a, and the other end is attached to an engagement piece 16a formed near the boss 16. By being fixed, when the operation lever 6 is in an unloaded state, the operation lever 6 is stopped at the initial rotation position by the elasticity of the winding spring so that the hit ball is not fired.

  In the hitting ball launching handle configured as described above, a finger is put between the chevron ridges 11a to 11c of the finger hooking protrusion 10, the operation lever 6 is rotated against the elasticity of the winding spring 18, and the finger By gripping the grip portion 5 with the palm of the hand, the operation lever 6 can be held at a desired rotation angle (rotation state). For this reason, the firing strength of the hit ball can be adjusted as desired, and the grip portion 5 has a substantially spherical shape, and the finger hooking projection 10 extends back and forth along its spherical surface. The number of fires can be adjusted as desired by any number of people. In addition, the finger hooking protrusion 10 is formed with a hollow opening on the lower surface, so that the finger hooking protrusion having the desired size and shape can be formed while keeping the thickness of the plastic constant, so that the upper surface is smooth. The curved shape can be used to fit the shape of a finger. There is no fear that the parting line of the mold will be difficult to see when it appears on the surface of the finger hooking projection. For this reason, there are advantages such as a novel design, excellent operability, and fatigue of fingers even when playing for a long time.
