TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hitting ball shooting operation handle in a pachinko gaming machine configured to partially vibrate.
[0002]
[Prior art]
A vibration generator is provided on a hit ball firing operation handle of a pachinko game machine, and by vibrating the handle at an appropriate time during the progress of the game, a vibrator that conveys an excitement state to the player with a tactile sensation and makes the game more exciting The hit ball launch operation handle is already known from the patent application of the present inventors.
[0003]
[Problems to be solved by the invention]
By the way, since the internal space of the conventional hit ball firing operation handle cannot afford a large vibration generator, it is necessary for the player to transmit vibrations of sufficient strength to the hand with a small vibration generator, In the conventional structure, the vibrating portion vibrates the entire front surface of the handle or vibrates most of the handle. Therefore, there is a disadvantage that vibration of sufficient strength cannot be transmitted, and the impact on the player has not been sufficient.
[0004]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and vibration of sufficient strength is transmitted to the palm of a player even with a small vibration generator by vibrating only a part of the front surface of the handle body. It is intended to provide a hit ball launch operation handle of a pachinko gaming machine which can excite a game.
[0005]

For this purpose, the hitting ball firing operation handle of the pachinko gaming machine according to the present invention has an operating lever for adjusting the hitting ball firing force provided rotatably on the outer periphery, and a substantially circular opening on the front surface of a substantially spherical handle body. A vibration transmission board formed in a substantially spherical shape that is connected to the surface of the handle main body and protrudes forward is mounted with an elastic member interposed in the opening, and the electromagnetic coil and the permanent magnet face each other in close proximity An electromagnetic vibration generator is provided in the handle main body and the vibration is transmitted to the vibration transmission board.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a pachinko gaming machine to which the present invention is applied. 1 is a glass door frame in which a game board 3 is disposed in a window hole 2, and 4 is provided below the glass door frame and is provided on the front surface for firing. A lower front plate on which a ball tray (upper plate) 5 for supplying a pachinko ball is formed, and a lower ball plate 6 is provided further below the front lower plate to store pachinko balls overflowing from the ball tray 5 on the front surface. (Lower plate) 7 is a front lower plate provided with a hit ball firing operation handle 8 at the right end. The surface of the glass door frame 1 is provided with an uneven design reminiscent of a volcanic crater.
[0007]
As shown in FIGS. 2 to 4, the hitting ball firing operation handle 8 has a handle body 12 having a substantially spherical shape (specifically, a cloud shape extending to one side) by joining the base portion 10 and the front cover portion 11 together. The base 10 is formed and fixed to the front surface of the front lower plate 6 by screws 13 so that the communication connector 14 provided in the base 10 matches the mating connector 15 provided on the front lower plate 6. A bearing 16 is provided on the front surface of the base 10 to rotatably support an annular operation lever 17, and the front cover 11 is fixed to the front of the operation lever 17 via a mounting plate 18 by screws 19. A variable resistor 20 is fixed to the center of the mounting plate 18 by a nut 21, and a rotating shaft 22 of the variable resistor is fixed to a center of the operation lever 17 via a collar 23. A single-use switch 24 and its operation button 25 are provided on one side of the mounting plate 18, and an arc-shaped conductive member 26 is fixed to an outer peripheral edge of the mounting plate 18. For this reason, by touching the conductive member 26 with a finger and operating the operation lever 17 to adjust the rotation angle, the resistance value of the variable resistor 20 is changed, and the signal of the variable resistor is transmitted to the ball launching device (not shown). ), The firing force of the hit ball hit on the game board can be freely adjusted. Reference numeral 27 denotes a coil spring provided for returning the rotation of the operation lever 17.
[0008]
Reference numeral 30 denotes a vibration transmission board, which is a transparent plastic board 31 having a front surface formed in a spherical shape having substantially the same curvature as the front cover portion 11 and a front face seen through the front of the transparent plastic board 31. It comprises a plastic design board 33 on which an obtained concavo-convex pattern 32 is formed, and this design board 33 is superposed on the rear surface of the transparent plastic board 31 and is integrally assembled.
The front cover portion 11 is formed in a substantially spherical shape so as to surround the variable resistor 20 and the single-shot switch 24, and has a substantially circular opening 34 in the front surface thereof. The elastic member 35 made of a rubber O-ring is interposed between the rear edge of the opening and the vibration transmission board 30. As a result, the vibration transmission board 30 is connected to the substantially spherical surface of the front cover portion 11 and projects forward in a substantially spherical shape.
[0009]
Reference numeral 36 denotes an electromagnetic vibration generator provided in the handle main body 12. In the electromagnetic vibration generator, as shown in FIG. 5, a metal thin plate 39 having elasticity is fixed to each of three mounting shafts 37 protruding from the rear surface of the front cover unit 11 with screws 38. A cylindrical body 40 is fixed to the front surface of the metal plate 39, an elastic plate 41 and an electromagnetic coil 42 are provided at the center of the cylindrical body, and a disk-shaped magnetic iron yoke 44 to which a permanent magnet 43 is fixed is annularly formed of elastic plastic. By supporting the outer peripheral edge of the cylindrical body 40 by the support piece 45, the electromagnetic coil 42 and the permanent magnet 43 are opposed to each other in a close state. The screw 38 is screwed to press the outer peripheral edge of the cylindrical body 40 against the outer peripheral edge of the vibration transmission board 30. Reference numeral 44 denotes a positioning pin formed on the annular support piece 45.
[0010]
For this reason, when a low frequency current of several Hz to several tens Hz is applied to the electromagnetic coil 42, the vibration generated by the electromagnetic action is transmitted to the vibration transmission board 30 via the cylindrical body 40, and the vibration transmission board is vibrated. Therefore, if the player holds the handle body 12, the vibration can be felt by the palm. As described above, since the vibration transmission board 30 can be made to have a relatively small mass in the form of projecting forward in a substantially spherical shape, the vibration transmission board 30 can be vibrated sufficiently with a small electromagnetic vibration generator. It can have a strong impact. By attaching the vibration transmission board 30 to the opening 34 with the elastic member 35 interposed, the restraint of the vibration transmission board 30 in the opening 34 is reduced, and free vibration is promoted.
[0011]
Also, since the vibration transmitted to the palm of the player can be reduced by transmitting the vibration to the palm of the player, the operability can be improved without hindering the fine adjustment of the rotation angle of the operation lever 17 with the fingertip. Does not harm.
[0012]
