Then, on the free end side of the operating piece 29c, a button convex portion 29d is provided on the upper surface, and a switch presser 29e is projected on the lower surface, and as shown in the enlarged view of FIG. It faces the upper surface of the switch button 29f of the sub switch 29b through the through hole 16i of 16b. The sub switch 29b is, for example, a known micro switch, and the switch button 29f is always urged in the direction of protruding outward by the elasticity of an internal spring (not shown), and the internal contact is closed in this state. ing. Therefore, when the switch button 29f protrudes to the outside, the electric striking ball 13 operates on the condition that other conditions are satisfied, and stops even if the switch button 29f is lowered.

The temporary firing stop means 29 is configured as described above. When no force is applied to the button projection 29d of the operating piece 29c, the switch presser 29e is positioned on the switch button 29f of the sub switch 29b by the elasticity of the operating piece 29c. In this state, the electric striking ball 13 is operable. Accordingly, in this state, the electric ball striking rod 13 operates when other predetermined conditions such as the above-described main switch 27 is turned on.
On the other hand, when the electric ball striking rod 13 is operating, if the button convex portion 29d of the operating piece 29c is pressed with a finger, the switch presser 29e is lowered and the switch button 29f of the sub switch 29b is pressed. However, the electric hitting ball 13 stops and the game ball stops firing. When the finger is released from the button convex portion 29d at an arbitrary timing, the operating piece 29c moves backward due to its own elasticity, the switch presser 29e rises, and the switch button 29f of the sub switch 29b also rises. 13 resumes operation.
As described above, when the player himself presses and releases the button convex portion 29d of the operating piece 29c, the launch of the game ball can be temporarily stopped at an arbitrary timing for an arbitrary time.

The button projection 29d of the operating piece 29c comes out of the cover member 16j. The cover member 16j is a touch switch having a conductive structure. When the player's hand is touching the cover member 16j, the electric hitting basket 13 can be operated only when the hand is touching. And

  8 and 10, reference numeral 16m denotes a wiring post having a U-shaped horizontal section projecting downward from an end of the hand mounting portion 16b on the side opposite to the sub-switch 29b, and the wiring post 16m is connected to the operation base 15. The tip of the communication hole 23 is inserted into the mechanism chamber 15d, and the wiring of the sub switch 29b (not shown) and the wiring of the touch switch of the cover member 16j (shown in FIG. (Not shown) is drawn into the mechanism chamber 15d.

[Launching power control device ... Operation unit + Operation base]
The operating portion 16 has an L-shape projecting from the shaft hole 22 of the operating base 15 through the rotation shaft 16h protruding from the shaft substrate 16e at one end of the bottom portion 16a, and protruding from the other end of the bottom portion 16a. The bent piece 16 f is installed on the upper surface of the operation base 15 in a state where the bent piece 16 f is passed through the arc-shaped long hole 25 of the operation base 15. The operation unit 16 is large enough to be covered with one hand of an adult male with the fingertip slightly opened as described above. Therefore, a part of the hand that operates on the upper surface of the operation base 15 in an operation posture. Appears.
As shown in FIG. 3, the operation unit 16 has the rotation shaft 16h (= shaft hole 22), which is the center of swinging rotation, disposed at a position closer to the player, and the arc side of the fan-shaped locus is anti-game. The direction is toward the person side (front side of the front frame 4).

  In a state where the operation unit 16 is installed on the upper surface of the operation base 15, the protrusion of the track portion 24 of the operation base 15 and the recess of the sliding portion 16 g of the operation unit 16 are in a loosely fitted state. Since the track portion 24 of the operation base 15 and the sliding portion 16g of the operation portion 16 have a circular arc shape in plan view with the same center (the rotation shaft 16h and the shaft hole 22), the operation portion 16 has the operation base 15 The center of the rotation shaft 16h (= shaft hole 22) is set as a fixed point P while the track portion 24 and the sliding portion 16g are combined, and the head can be swung around the fixed point P.

  On the other hand, an L-shaped bent piece 16f projecting downward from one end of the bottom portion 16a of the operation portion 16 is a circular arc in plan view having the same center (rotating shaft 16h, shaft hole 22) as the track portion 24 and the sliding portion 16g. In order to move in the arc-shaped elongated hole 25 of the shape, the swinging rotation of the operation unit 16 is not hindered. Furthermore, as shown in the enlarged view of FIG. 10, the L-shaped bent piece 16f is set so as to be hooked from the inside to the opening edge of the arc-shaped elongated hole 25 of the operation base 15, and the L-shaped bent piece 16f is caught. Thus, one end of the operation unit 16 is prevented from floating. A downward rib 25a protrudes along the lower surface of the opening edge of the arc-shaped long hole 25 of the operation base 15, and the contact portion of the operation portion 16 with the L-shaped bent piece 16f is made substantially linear to cause friction. Thus, the light movement of the operation unit 16 is not hindered.

Further, the L-shaped bent piece 16f acts on the swing lever 28 of the main switch 27 to turn off the main switch 27 when the operation portion 16 is at the position of the solid line in FIG. 3 closest to the player side. . Thus, when the main switch 27 is turned off, the electric ball striking rod 13 does not operate and the firing operation of the ball launching member 9 stops.
Therefore, in the present embodiment, the position of the operation portion 16 shown by the solid line in FIG. 3 that is closest to the player side on the operation base 15 is the initial position associated so that the firing operation of the ball launching member 9 stops.

[Launch force adjusting device ... Adjusting means]
The adjusting means 17 for increasing and decreasing the firing force of the ball launching member 9 is a variable resistor capable of changing the pulsed voltage value applied to the rotary solenoid 13b of the ball launching member 9, as shown in FIG. The resistor body 17a has a substantially cylindrical shape, and the adjustment shaft 17b protrudes from the center of the resistor body 17a. And it is attached to the back side (lower surface) of the upper surface member 15a of the operation base 15 through the support member 30 screwed to the upper surface member 15a with the adjustment shaft 17b facing upward. Since the resistor main body 17a of the adjusting means 17 protrudes below the support member 30, an oval cup portion 15e is provided on the bottom surface member 15c of the operation base 15 to provide resistance. The main body 17a is accommodated.

[Launching power adjusting device ... Adjusting means + operation unit]
As shown in FIGS. 4, 5, 9, and 10, the adjusting means 17 and the operation unit 16 are gears that are combinations of a substantially sector-shaped driving internal gear 31 and a substantially sector-shaped driven spur gear 32. They are connected by a transmission mechanism.

  The driving internal gear 31 is located at a position along the back side of the upper surface member 15a of the operation base 15 and is fixed to the lower end of the rotating shaft 16h of the operation unit 16 with a screw. The head can be swung. The driving internal gear 31 has teeth 31b, 31b,... Constituting the internal gear on the inner side of the peripheral wall 31a of the circumferential portion, and has a flange piece 31c on the outer side of the peripheral wall 31a. It passes between the grooves 33a of the rotating roller 33 that is pivotally attached to the 15 upper surface members 15a. Therefore, even if the weight balance of the driving internal gear 31 is fan-shaped, even if it is biased toward the peripheral wall 31a, there is no possibility that the peripheral wall 31a is lowered or fluctuated by the support of the rotating roller 33. Therefore, the swinging rotation of the driving internal gear 31 is stabilized.

  On the other hand, the driven spur gear 32 is located below the driving internal gear 31 and is in a state where a downward shaft tube portion 32a projecting from a portion corresponding to the center of the fan is placed on the upper end of the adjusting shaft 17b of the adjusting means 17. It is fixed and rotates integrally with the adjusting shaft 17b. .. Are formed on the outer periphery of the driven spur gear 32. The teeth 32b, 32b... And the teeth 31b, 31b of the driving internal gear 31 are shown in FIGS. Engage as shown. Therefore, when the driving internal gear 31 is swung and pivoted integrally with the operation unit 16 as shown in FIGS. 4 to 5, the rotation is transmitted from the driving internal gear 31 to the driven spur gear 32 and the adjusting shaft 17b rotates. The electrical resistance of the means 17 changes.

[Launching force adjusting device ... Returning means for operation section]
The operation section return means 18 urges the operation section 16 toward the initial position, that is, the position associated with the firing operation of the ball launching member 9 to stop, and the driven spur gear 32. It is comprised by the torsion coil spring 18a with which the outer periphery of the axial cylinder part 32a was mounted | worn. The torsion coil spring 18a urges the driven spur gear 32 counterclockwise in FIGS. 4 and 5 by engaging the spring shafts 18b and 18c at both ends with the bottom surface of the driven spur gear 32 and the support member 30, respectively. It is supposed to be. The urging force of the torsion coil spring 18a is transmitted from the driven spur gear 32 to the driving internal gear 31 and becomes a rotational force that moves the operating portion 16 toward the initial position. Therefore, even if the operation unit 16 is moved to a position away from the initial position by the player, if the player releases his / her hand from the operation unit 16, the operation unit 16 is automatically returned to the initial position by the urging of the torsion coil spring 18a. To return.

  In addition, since the operation part return means 18 of embodiment was comprised by the torsion coil spring 18a as mentioned above, there exists a possibility that it may return too vigorously at the moment when a player's hand leaves | separates from the operation part 16. Therefore, in the embodiment, the buffering means 18d is provided so that the backward movement of the operation unit 16 to the initial position is performed gently. The buffering means 18d is, for example, a rotary damper that generates a braking force by the viscous resistance of oil. The damper main body 18e is fixed to the upper surface side of the support member 30 as shown in FIG. The pinion gear 18f protruding from the upper portion of the damper main body 18e and the internal gear 32c formed on the lower surface of the driven spur gear 32 are engaged with each other, so that the driven spur gear 32 is moved to the initial position by the torsion coil spring 18a of the operating portion return means 18. When returning backward, the braking force due to the viscous resistance of the oil is applied to the pinion gear 18f, so that the operation unit 16 is slowly returned.

[Launching power control device ... Operating part levitation biasing means]
When the player's hand is not placed on the hand placement portion 16b of the operation portion 16, the operation portion levitation biasing means 20 moves the bottom portion 16a of the operation portion 16 to the operation base as shown in FIG. The gap 19 is formed so as to float from the upper surface of the table 15.
As shown in FIG. 8, the operation unit levitation urging means 20 includes a fixed main plate 20b having two fixed pins 20a and 20a projecting on the lower surface of the center, and an elastic extending on both sides of the fixed main plate 20b. Receiving tube portion 16n having wing pieces 20c, 20c and leg pieces 20d, 20d projecting on the lower surface of the end portion of the elastic wing piece 20c, the fixing pins 20a, 20a being formed on the bottom portion 16a of the operation portion 16. , 16n to fix the fixed main plate 20b, and the leg pieces 20d, 20d of the elastic blade pieces 20c, 20c to the upper surface of the operation base 15 from the leg through holes 16p, 16p provided in the bottom portion 16a of the operation section 16. It protrudes (between a pair of track portions 24, 24), so that the bottom portion 16 a of the operation portion 16 is lifted from the upper surface of the operation base 15. At this time, the operation unit 16 is supported by the elasticity of the elastic blades 20c and 20c of the operation unit levitation biasing means 20, and therefore the operation unit levitation biasing means 20 supports at least the weight of the operation unit 16. It has enough strength.

As described above, in a state where the operation unit 16 is supported by the leg pieces 20d and 20d of the operation unit levitation biasing means 20, the operation unit levitation biasing means 20 is formed of a resin having excellent lubricity (for example, a fluororesin). If this is done, the frictional resistance with the operation base 15 can be reduced, so that there is an effect that the operation section 16 can be moved backward easily by the operation section return means 18.
Further, even when the operation part levitation biasing means 20 is not formed with such a resin having excellent lubricity, the operation part can be prevented by avoiding the entire contact between the bottom 16a of the operation part 16 and the surfaces of the operation base 15. 16 can be made less susceptible to an increase in frictional resistance caused by dirt on the bottom 16a of the operation base 15 and the operation base 15, and in any case, the operation unit 16 can be easily moved back by the operation unit return means 18. effective.

  It should be noted that the fact that the operation part 16 can be easily moved backward by the operation part return means 18 as described above means that the spring constant of the torsion coil spring 18a of the operation part return means 18 can be reduced. In such a case, the effect that the operation in the direction against the urging of the torsion coil spring 18a of the operation unit 16 (the direction of rotating from the solid line position to the two-dot chain line position in FIG. 3) can be performed with a small force, As a result, it also leads to an effect that can reduce a player's fatigue.

  On the other hand, when the player places his / her hand on the hand rest 16b of the operation section 16, the operation section levitation urging means 20 has a strength that can not resist the increase in the weight of the hand, that is, the elastic wing piece. 20c and 20c are set to bend. Therefore, when the player places his / her hand on the hand-mounted portion 16b of the operation portion 16, the elastic wing pieces 20c and 20c of the operation portion levitation urging means 20 that supported the operation portion 16 as described above are bent, and FIG. As shown in b), the operation portion 16 is lowered together with the fixed main plate 20b, and the bottom portion 16a of the operation portion 16 and the upper surface of the operation base 15 are in contact with each other. Then, since the bottom 16a of the operation unit 16 and the upper surface of the operation base 15 are in contact with each other, the operation unit 16 may be stopped at an arbitrary position against the bias of the operation unit return means 18. It becomes easy.

[Others]
9 and 10, reference numeral 34 denotes a vibration unit provided in the rounded portion 21 of the operation base 15. The vibration unit 34 can be moved up and down by a base 34a fixed inside the operation base 15, a pair of left and right support springs 34b and 34b attached to the base 34a, and the support springs 34b and 34b. And a receiving portion 34d that is attached to the upper surface of the vibration member 34c and protrudes from the inside of the operation base 15 toward the upper surface of the round portion 21.

As shown in FIG. 3, the receiving portion 34 d has an arc shape in plan view along the rounded portion 21 of the operation base 15, and protrudes around the shaft substrate 16 e of the operation portion 16, so that the player can operate the operation portion 16. A part close to the wrist of the palm is placed when operating.
Accordingly, by operating the vibration member 34c, the vibration of the vibration unit 34 is transmitted to the player's hand through the receiving portion 34d. For example, if the vibration member 34c is operated at an appropriate timing in accordance with the content of the game. It is possible to increase the interest of the game, or it can be used for the purpose of relieving the player's hand fatigue by vibration. When the vibration unit 34 is used for a massage machine, a vibration switch for the player may be provided so that the player can freely operate.

[How to use pachinko machine]
Next, a method for using the pachinko machine of the present invention will be described with a focus on the launching force adjusting device 10.
The pachinko machine before the start of the game is in the state of FIG. 1, and the initial position where the operation unit 16 of the firing force adjusting device 10 is closest to the player side by the urging of the operation unit return means 18 as shown in FIG. 3. It is in. In the state in which the operation unit 16 is in the initial position, the main switch 27 provided inside the operation base 15 by the action of the L-shaped bent piece 16f of the operation unit 16 and the swing lever 28 as shown in FIGS. It is OFF and the ball launching member 9 is stopped. At this time, the operation unit 16 forms a gap 19 between the operation base 15 and the upper surface of the operation base 15 due to the elasticity of the elastic blade pieces 20c, 20c of the operation unit levitation biasing means 20 as shown in FIGS. Supported while kept.

  Therefore, when playing a game with this pachinko machine, first, the game ball is put into the ball tray 6 of the front frame 4, and the portion near the wrist of the palm of the right hand on the receiving portion 34 d in the rounded portion 21 of the operation base 15. , And put the palm and fingers on the hand rest 16 b of the operation section 16. At this time, the entire edge of the player's right hand including the little finger, for example, is placed on the upper surface of the operation base 15, or the thumb side is placed on the upper surface of the operation base 15, or the thumb and little finger are placed on the operation base 15. A finger other than the palm and the finger placed on the operation base 15 is placed on the hand placing portion 16b.

  When the hand is placed on the operation unit 16, the elastic wing pieces 20c and 20c of the operation unit levitation urging means 20 are bent as shown in FIG. The bottom part 16a and the upper surface of the operation base 15 come into contact with each other. Further, since the hand placed on the operation unit 16 touches the cover member 16j, the touch switch of the cover member 16j is turned on.

  Next, when the right hand to be operated is moved mainly clockwise around the wrist in FIG. 3 and a force is applied to the operation unit 16, the operation unit 16 rotates about the rotation shaft 16h which is a fixed point P. By this rotation of the operation unit 16, the L-shaped bent piece 16f is separated from the swing lever 28 as shown in FIG. 5, so that the switch piece 27a of the main switch 27 is released from being pressed and the main switch 27 is turned on. Thereby, the electric ball striking rod 13 of the ball launching member 9 starts the ball hitting operation.

  Normally, the game ball thrown into the ball tray 6 is stopped in front of the launching portion of the launch rail 12 by a ball supply device (not shown) linked to the electric ball striking rod 13 of the ball launching member 9. When the electric striking ball 13 starts a hitting operation, it is supplied one by one to the launching portion of the launching rail 12 in conjunction with the movement.

  On the other hand, the rotation of the operation portion 16 is transmitted from the rotation shaft 16h to the adjustment shaft 17b of the adjustment means 17 through the driving internal gear 31 and the driven spur gear 32 according to the gear ratio of the gear transmission mechanism. Accordingly, the adjusting shaft 17b rotates and the electric resistance of the variable resistor changes. As a result, the voltage applied to the rotary solenoid 13b of the electric ball striking rod 13 changes, and the striking force of the rod main body 13d changes. Therefore, the player only has to stop the operation unit 16 at the position when the hitting force becomes the targeted strength.

  Next, when it is desired to temporarily stop the launch of the game ball while the game ball is being fired, the button convex portion 29d projecting from the hand placement portion 16b of the operation unit 16 is pressed with, for example, the right hand index finger. Then, the sub switch 29b in the operation unit 16 is turned OFF, and the electric ball striking rod 13 stops during that time. Then, when the finger is released from the button convex portion 29d at an appropriate timing, the sub switch 29b is turned on, and the operation of the electric ball striking rod 13 is resumed. In the meantime, when the operation unit 16 is not moved, it can be resumed with the same striking force as before the stop.

  Next, when the player completely releases the hand from the operation unit 16 during the game, first, the touch switch of the cover member 16j of the operation unit 16 is turned off, so that the electric ball strut 13 is stopped at that time, and the operation is performed at the same time. The leg piece 20 d of the operation unit levitation biasing means 20 protrudes from the bottom part 16 a of the part 16, and the bottom part 16 a of the operation part 16 is separated from the upper surface of the operation base 15. Then, due to the biasing of the torsion coil spring 18a of the operating portion return means 18 and the action of the buffer means 18d, the operating portion 16 gently returns to the initial position, and the L-shaped bent piece 16f of the operating portion 16 hits the swing lever 28. The main switch 27 is turned off.

  By the way, conventionally, for example, a coin or similar foreign matter is sandwiched between the handle grip 102 of the conventional example of FIG. There are players who want to make adjustments easier. Such a selfish act of the player is unreasonable in that a coin or the like is forcibly inserted between the handle grip 102 and the dial 103, that is, between the fixed portion and the rotating portion, so that a part of the firing force adjusting device 10 is damaged. Therefore, effective measures were desired from the amusement hall side as a victim.

  On the other hand, the firing force adjusting apparatus 10 of the embodiment aligns the track portion 24 of the operation base 15 and the sliding portion 16g of the bottom portion 16a of the operation portion 16 as described above, and makes the contact surfaces of both non-linear. By doing so, disc-shaped coins and the like cannot be inserted. Therefore, it is possible to prevent an illegal act in which a player tries to insert a coin or the like between the operation unit 16 and the operation base 15.

  Note that the combination of the embodiment in which the track portion 24 of the operation base 15 is raised in a convex shape and the sliding portion 16g of the operation portion 16 is formed in a groove shape that is dug in a concave shape as in the embodiment is reversed. Is substantially synonymous with a combination in which a groove shape is formed by digging in a concave shape and a groove shape in which the sliding portion 16g is raised in a convex shape. Further, the number of the track portions 24 and the sliding portions 16g may be a single number in addition to a plurality as in the embodiment. When the track portion 24 and the sliding portion 16g are singular, it is preferable to form a curved shape having a width extending from the minimum diameter track portion 24 of the embodiment to the maximum diameter track portion 24 or slightly smaller than this. Even in such a combination of the single track portion 24 and the sliding portion 16g, a disk-shaped coin or the like cannot be inserted if the contact surface is curved.

As mentioned above, although embodiment of this invention was described, of course, this invention is not limited to the said embodiment. For example, in the embodiment, a pachinko machine in which a game ball is thrown into the ball tray 6 to play a game as an example of a ball game machine is illustrated, but a so-called encapsulated pachinko machine that circulates a game ball in the machine, or a sparrow ball type The same can be applied to other ball and ball machines.

  Further, in the embodiment, the touch switch is provided on the cover member 16j of the hand placement portion 16b of the operation portion 16, but for example, on both side surfaces of the hand placement portion 16b of the operation portion 16 as shown by a two-dot chain line in FIG. A touch switch 35 may be provided.

  In the embodiment, the fixed point P that is the center of the swinging rotation of the operation unit 16 is set on the operation base 15, but the fixed point P may be set outside the operation base 15. FIG. 11 shows the embodiment, and two large-diameter and small-diameter arc-shaped rails 36, 36 centering on the fixed point P are installed in the operation base 15 and the arc-shaped rail is disposed on the operation section 16. Rollers 37, 37... That can roll in contact with 36, 36 are provided. In this case, since the operation unit 16 moves along the two arc-shaped rails 36 and 36, the operation unit 16 is swung around the fixed point P that is the center of the arc of the arc-shaped rails 36 and 36.

  In such an embodiment, the fixed point P that is the center of swinging of the operation unit 16 can be set near the player's wrist without enlarging the operation base 15. Since the movement and the movement of the operating hand can be approximated, it is possible to further enhance the effect of the present invention in which a game can be played with an easy and comfortable posture.

  In the embodiment, a rotary solenoid 13b is used as a drive source for moving the rod main body 13d of the ball launching member 9, and a variable resistor for adjusting the output of the rotary solenoid 13b as the adjusting means 17 of the firing force adjusting device 10. However, as shown in FIG. 12, for example, an electric motor 13f and a traction spring (not shown) are adopted as a driving source for moving the rod main body 13d of the ball launching member 9, while the firing force adjusting device 10 is used. As the adjusting means 17, a known method for adjusting the tension of the spring for pulling the rod main body 13 d can be adopted.

  That is, in FIG. 12, 17c is a driving bevel gear fixed to the rotating shaft 16h of the operation unit 16, 17d is a driven bevel gear meshing with the driving bevel gear 17c, and 17e rotates integrally with the driven bevel gear 17d. A handle shaft, 17f is a pulley fixed to the end of the handle shaft 17e, 17g is a wire wound around the pulley 17f, 37 is a spring unit that urges the saddle body 13d in the launch direction, and 13g is an output of the electric motor 13f. The cam plate is fixed to the shaft and engages with the rod main body 13d to tilt the rod main body 13d in the opposite direction.

  In this case, the electric ball 13 has the cam plate 13g rotated in a certain direction by the operation of the electric motor 13f, and the rotation of the cam plate 13g causes the rod body 13d to counteract against the bias of the spring unit 37. 2 is tilted in the direction (the direction of the two-dot chain line from the broken line in FIG. 2), and at the moment when the cam plate 13g is detached from the rod body 13d, the rod body 13d is vigorously moved backward by the bias of the spring unit 37 and The game ball in the launching unit is launched.

  On the other hand, the adjusting means 17 of the embodiment shown in FIG. 12 is configured such that when the operating unit 16 is rotated in the direction of the two-dot chain line in FIG. The pulley 17f rotates via 17d and the handle shaft 17e, and the tension of the spring built in the spring unit 37 is increased by the tension of the wire 17g wound around the pulley 17f, so that the firing force of the rod main body 13d can be increased. In the embodiment shown in FIG. 12, the operation unit return means 18 for returning the operation unit 16 to the initial position is the spring unit 37, the wire 17g, the pulley 17f, the handle shaft 17e, the driven bevel gear 17d, and the driving bevel gear. 17c.

  As described above, the embodiment of FIG. 12 is an example in which the operation unit 16 and the electric ball striking rod 13 are mechanically connected, and a winding transmission mechanism such as a belt or a chain is adopted as well as a gear transmission mechanism other than the illustrated combination. May be.
