In the first sliding member 25, a member main body 25b is screwed to the front surface of the vertically long plate member 25a, and arcuate portions 25c for holding the linear bearings 30a and 30b are formed at both upper and lower ends of the member main body 25b. By inserting the liner bearings 30a and 30b into the outer periphery of the liner shafts 28a and 28b in the region on the left side of the stopper 24a, the liner bearings 30a and 30b are inserted along the liner shafts 28a and 28b in the region on the left side of the stopper 24a. It is supported so that it can slide. A rotary encoder 31 is fixedly attached to the back side of the member main body 25b, and a gear 32 is fixedly attached to the rotary shaft of the rotary encoder 31. Further, the limit switch 33 is fixedly fixed to the left side portion of the member main body 25b from the gear 32, and a pair of stop pieces 25d are formed on the left side edge of the member main body 25b. The electric signal transmitted from the rotary encoder 31 and the limit switch 33 is input to the control board of the ball launching device. Further, a light-shielding piece 34 capable of operating the optical sensors 29a and 29b is fixed to the back surface of the vertically elongated plate material 25a.
Then, one end of the pair of coil springs 35a and 35b is attached to the vertically long plate member 25a, and the other end of the coil springs 35a and 35b is attached to the stop piece 24b. Therefore, the first sliding member 25 is urged to the right by the elastic tension of the coil springs 35a and 35b, and normally, the first sliding member 25 abuts on the stopper 24. It can be stopped in the state of.

The second sliding member 26 has a member main body 26b screwed to the back surface of the folded plate member 26a, and arcuate portions 26c for holding the linear bearings 36a and 36b are formed at both upper and lower ends of the member main body 26b. By inserting the liner bearings 36a and 36b into the outer periphery of the liner shafts 28a and 28b, the liner bearings 36a and 36b are provided so as to be slidable along the liner shafts 28a and 28b on the front side of the first sliding member 25. Be done. Then, the upper end portion of the folded plate member 26a is bent forward to form a hook-shaped locking portion 26d, and the locking portion 26d is projected forward from the slit 27a. Further, a hook-shaped locking portion 26f is formed by bending forward at the lower end portion of the folded plate material 26a, and the locking portion 26f is projected forward from the slit 27b. Further, a rack tooth 37 that meshes with the gear 32 is horizontally integrally formed on the member main body 26b, and a rod-shaped actuating piece 38 that can operate the limit switch 33 and a rod-shaped stay 39 are formed on the rack tooth 37. It is formed so as to be parallel to.

In this way, the second sliding member 26 is arranged so as to be slidable along the liner shafts 28a and 28b on the right side of the first sliding member 25, so that the rack teeth 37 can be arranged with the gear 32. When the second sliding member 26 slides, the rotary encoder 31 operates, and the sliding position of the second sliding member 26 is detected as an electric signal by the rotary encoder 31. Further, one end of a pair of coil springs 40a and 40b is attached to the folded plate member 26a of the second sliding member 26, and the other end of the coil springs 40a and 40b is attached to the stop piece 25d. The second sliding member 26 is urged to the left by the elastic tensile force of the springs 40a and 40b, and the second sliding member 26 normally has the arc-shaped portion 26c on the arc-shaped portion 25c. It can be stopped in a state of contact. At this time, the actuating piece 38 presses and operates the limit switch 33, an electric signal from the limit switch 33 is input to the control board of the hitting ball launching device, and the hitting ball launching is stopped. In this state, the first sliding member 25 and the second sliding member 26 are in the initial positions, and the initial state of the guide rail body 23 is shown in FIG. 7 (a).

The locking portion 26d projects from the lateral hole 20a of the side wall panel 20 to the front surface of the side wall panel 20, and the locking portion 26f projects from the horizontally long notch 20b to the front surface of the side wall panel 20. Then, the manual operation unit 21 is guided by the guide rail body 23 and attached to the locking portion 26d and the locking portion 26f so as to be able to reciprocate in a substantially linear shape. The manual operation unit 21 forms the grip portion 21a in a substantially vertical cylindrical shape, and arranges the locking portion 26d on the upper surface of the horizontal plate portion 21b formed at the upper end of the grip portion 21a to form a horizontal lid 21c. By fixing the horizontal plate portion 21b to the locking portion 26d by screwing from above, the horizontal plate portion 21b is locked to the lower surface of the horizontal plate portion 21d formed at the lower end of the grip portion 21a in the same manner as the upper end portion. The horizontal plate portion 21d is fixed to the locking portion 26f by arranging the portion 26f and fastening the screw. Further, a switch body 21f is provided in the grip portion 21a, a push button 21h is arranged in a mounting hole 21g opened near the upper end portion of the grip portion 21a, and the switch body 21f is turned on / off by the push button 21h. I am trying to be operated. The surface of the grip portion 21a is conductively plated, and when the player grips the grip portion 21a, the touch state is electrically detected, and the electric signal controls the hitting ball launching device. It is input to the board and the pachinko ball is hit and fired. Even if the grip portion 21a is gripped, pressing the push button 21h suspends the firing of the pachinko ball, so that the player can hit and fire the hit ball at a desired timing.

Further, in a state where the grip portion 21a is grasped and the finger is released from the push button 21h, the grip portion 21a is pulled toward the front against the elasticity of the 40a and 40b (in FIG. 1, the grip portion 21 is directed to the right). By moving the rack teeth 37, the rack teeth 37 rotate the gear 32, and an electric signal is transmitted from the rotary encoder 31 to the control board of the ball launching device. That is, assuming that the manual operation unit 21 of the guide rail body 23 is in this initial position, a firing intensity operation area is formed on the right side of the movement range of the manual operation unit 21 from this initial position, and the player grips the grip unit. If the grip portion 21a is gripped and the grip portion 21a is pulled toward the front from this initial position against the elasticity of the coil springs 40a and 40b, the hitting ball launching device becomes stronger as the grip portion 21a is pulled toward the front. Will hit. Note that FIG. 7B shows the operating state of the guide rail body 23 when the manual operation unit 21 is in the firing intensity operation range.

Further, on the back surface and the left side of the manual operation unit 21 from the initial position, an effect operation area for changing the display of the effect device such as the display 12a and the symbol variation display device 5 is provided. That is, by extending the arm while the player holds the grip portion 21a and moving the grip portion 21a to the left side from the initial position, the arcuate portion 26c of the second sliding member 26 becomes the second. Since the first sliding member 25 is moved to the left against the elasticity of the coil springs 35a and 35b in a state of being in contact with the arcuate portion 25c of the sliding member 25, the firing of the pachinko ball is stopped. First, the light-shielding piece 34 operates the optical sensor 29a in this state. From this state, the first sliding member 25 is further moved to the left as shown by an arrow in FIG. 7 (c), and is moved from the notch 24d to a state in which the rack teeth 37 and the rod-shaped stay 39 protrude. In some cases, the shading piece 34 activates the optical sensor 29b. The signals of the optical sensor 29a and the optical sensor 29b are input to the display control device of the symbol variation display device 5 and the display 12a, and the display of the symbol variation display device 5 and the display 12a and the like is the operating state and optical of the optical sensor 29a. It changes greatly depending on the operating state of the sensor 29b. For example, when the optical sensor 29a is operated while the reach state is displayed on the symbol variation display device 5, the display 12a displays light having a color reminiscent of a flame surrounding the movable member 17. do. Then, when the player extends his arm and moves the grip portion 21a further to the left, the light changes to a more brilliant color and the movable member 17 moves in the direction of the symbol variation display device 5. The light also swings in conjunction with the swing, and as a result, a [big hit] is invited, so that the movable member 17 can be a powerful weapon for the player to obtain the [big hit]. do. By producing an effect in which the movement of the movable member 17 is linked to the display of the symbol variation display device 5 and the display 12a in this way, the playability of the ball gaming machine can be significantly improved.
In this embodiment, only two optical sensors 29a and 29b are provided in the effect operation range, but a larger number of optical sensors, limit switches, encoders, etc. are provided, and the effect operation is performed by these sensors. By sequentially detecting the position of the manual operation unit 21 in the region, the effect according to the position of the manual operation unit 21 can be performed, and the effect can be made more varied and diverse.

In the hitting ball launching operation device according to the present invention, the manual operation unit 21 is moved substantially linearly as described above, and the strength of hitting ball launching is adjusted according to the amount of movement, so that the player can easily hit the ball with the desired strength. Since it can be fired and its adjustment is easy, the burden on the player's hand is reduced. Further, by moving the manual operation unit 21 provided so as to be able to reciprocate toward one end, the firing strength of the hitting ball launching device gradually increases, and the manual operation unit 21 is directed toward the other end. Since the effect state of the effect device related to the [big hit] is changed by the movement operation, the player can shoot a ball by simply changing the movement direction to the opposite side while holding the manual operation unit 21. The production state can be changed. Moreover, since the firing intensity operation area and the effect operation area are on extension lines of each other with the initial position in between, the change of the effect state by the operation of the player can always be accurately performed, and the ball game machine can be used. It is possible to improve the playability.
Further, in the present invention, since it is not necessary to provide a push button switch for directing on the front surface of the gaming machine as in the prior art, the space on the front surface of the gaming machine is relaxed and the degree of freedom in designing the gaming machine is increased.
Further, for the player, according to the present invention, the effect can be changed without operating the push button switch as in the conventional case, so that the player can press and hold the push button switch for a long time, which puts an excessive burden on the hand. There is no risk of hanging.
The support portion 22 provided so as to project forward on the lower side of the manual operation unit 21 can be used to support the wrist of the player during the game, thereby supporting the player's wrist. The burden on the hands is further reduced.
Further, since the linear shafts 28a and 28b are held horizontally and the linear bearings 36a and 36b slide along the linear shafts 28a and 28b, the player can arm while operating the manual operation unit 21. By weakening the force of the above and applying the weight of the arm to the manual operation unit 21, the gravity applied by the linear bearings 36a and 36b in the longitudinal direction with respect to the linear shafts 28a and 28b increases. , The frictional resistance between the linear shafts 28a and 28b and the linear bearings 36a and 36b increases. Therefore, the horizontal sliding resistance of the manual operation unit 21 increases only by the player weakening the force of the arm, and as a result, the manual operation unit 21 can be easily held at the player's desired position. Therefore, even with such a configuration, the burden on the hands and arms of the player during the game is reduced, and fatigue is reduced.

Further, in the embodiment shown in FIGS. 8 and 9, a bearing portion 22a is provided on the front surface of the ball game machine so as to project forward under the manual operation portion 21, and the upper surface of the support portion 22a has an uneven surface shape. The grip portion 21a and the horizontal board portion 21d of the manual operation unit 21 are configured to be able to move up and down slightly (about several millimeters) as shown in (a) and (b) of FIG. When the player relaxes the force of the arm while grasping the grip portion 21a, the grip portion 21a and the horizontal board portion 21d descend due to gravity, and the horizontal board portion 21d supports the bearing as shown in (b) of FIG. It comes into contact with the portion 22a, and the manual operation portion 21 is held in a fixed position by the frictional resistance thereof. By doing so, it becomes easier to keep the jumping amount of the pachinko ball constant at all times, and thus the fatigue caused by playing the ball game machine for a long time is further significantly reduced.

In the above embodiment, the manual operation unit 21 is reciprocated linearly in a slightly diagonal front-rear direction along the side wall panel 20, but is reciprocated left and right instead of the front-back direction. May be good. Alternatively, for example, the liner shafts 28a and 28b may be formed into a gently curved shape, and the manual operation unit 21 may be reciprocated along the curved line.
