Description

  The present invention relates to a gaming machine, and more particularly to a gaming machine that launches a gaming ball using a rotary solenoid as a driving source.

  For example, in a pachinko machine which is a kind of gaming machine, a method of hitting a gaming ball using a rotary solenoid as a driving source has been developed. The outline of the mechanism will be described with reference to FIG. A hammer 83 is fixed to the rotating shaft 82 of the rotary solenoid 81. The rotation range of the hammer 83 is restricted by the first buffer rubber 84 on the upper side and the second buffer rubber 85 on the lower side. The rotary solenoid 81 rotates the rotating shaft 82 and rotates the hammer 83 in the direction of the arrow in response to a pulse as shown in FIG. 14 from a control circuit (not shown). Then, the game ball supplied on the track of the hammer 83 is hit. Since the torque of the rotary solenoid 81 disappears after the ball is hit, the hammer 83 rotates in the reverse direction due to the reaction of collision with its own weight and the first shock absorbing rubber 84, hits the second shock absorbing rubber 85 and stops.

However, since the hammer 83 strikes the second shock absorbing rubber 85 vigorously, a bounce phenomenon occurs. For this reason, the bounce phenomenon is not settled by the timing of the next pulse, and there is a problem that the rotary solenoid 81 is driven in the bounce state. That is, the rotation start position of the hammer 83 is not determined by the bounce and the strength of the hit ball is not constant.
The present invention has been made paying attention to such problems existing in the prior art. An object of the invention is to provide a gaming machine capable of stably launching a game ball by suppressing the bounce of a hammer.

In order to achieve the above object, according to the first aspect of the present invention, a rotary solenoid that is driven based on a hitting ball pulse output and a rotary solenoid that is fixed to an output shaft of the rotary solenoid and rotates within a predetermined rotation regulation range. In a gaming machine having a hitting ball launcher equipped with a moving hitting ball and allowing the hitting ball to continuously perform hitting motion within the same rotation restriction range, output at a predetermined cycle The gist of the invention is that a constant electric power smaller than that of the hitting pulse is supplied to the rotary solenoid during the repetition period of the hitting pulse.
In such a configuration, the striking ball that has been vigorously reversely rotated is given a positive torque that is normally rotated by a constant output smaller than the ball-throwing pulse, so that the momentum in the reverse rotation direction is weakened. Therefore, the bounce of the hit ball at the initial position is eliminated.

The invention according to claim 2 includes a rotary solenoid that is driven based on a pulse output for hitting a ball, and a hitting ball that is fixed to the output shaft of the rotary solenoid and rotates within a predetermined rotation restricting range. Ending the duration of the hitting pulse output at a predetermined cycle in a gaming machine having a hitting ball launching device and allowing the hitting ball to continuously perform hitting motion within the same rotation restriction range The gist is that a sub-pulse having a smaller average amplitude than that of the same hitting ball pulse is output to the rotary solenoid later.
In such a configuration, the striking ball that has been vigorously reversely rotated is given a positive torque that is normally rotated by the sub-pulse, so that the momentum in the reverse rotation direction is weakened. Therefore, the bounce of the hit ball at the initial position is eliminated.

  In the invention described in claim 1 or 2, since the bounce at the initial position of the hitting ball is eliminated, the launching operation of the game ball is stabilized.

Hereinafter, embodiments in which the present invention is applied to a pachinko machine will be described with reference to the drawings. In the following description, the front side or the front side means the side facing the player, and the rear side or the back side means the opposite side.

  As shown in FIG. 3, a set board 22 as an open / close board is attached to the back side of the game board 5 so as to be openable / closable with respect to the pachinko machine body 4. The set board 22 is supported on the pachinko machine main body 4 by hinge portions 23 arranged at the top and bottom, and is attached to and detached from the pachinko machine main body 4 by pulling out and pushing in the open / close pins 26 arranged in a scattered manner on the board surface. Near the center of the set panel 22, a symbol display unit 31 as a control mechanism for controlling the variable display device 13 is disposed. A control device unit 32 as a control mechanism for performing electronic control of the pachinko machine, such as discharging a prize ball, is disposed adjacent to the unit 31. A prize ball tank 33 is disposed above the units 31 and 32. An input / output base 34 is arranged on the right side of the prize ball tank 33. A ball payout mechanism P is disposed below the input / output base 34. A safe ball processing mechanism Q is disposed below the ball payout mechanism P. A game ball launching mechanism R is disposed below the set board 22. The game ball launching mechanism R will be described later.

As shown in FIGS. 1 and 2, a door frame 15 is disposed on the front surface of the game board 5 so as to be opened and closed. The door frame 15 is in contact with the door frame support frame 7 in a closed state. The door frame 15 has a substantially square outer shape, and a large square hole 16 is formed in the center. Five through holes 24 are formed in the upper beam 19 above the door frame 15 in the horizontal direction. The through holes 24 correspond to the lamps 8 of the door frame support frame 7. When the door frame 15 is closed, the lamps 8 are disposed in the corresponding through holes 24. A translucent decorative panel 25 is disposed in front of the upper beam 19 and covers the through hole 24. The light from the lamp 8 brightly illuminates the light transmissive decorative panel 25 through the through hole 24. The left vertical frame 21 is formed with a large trapezoidal cutout 28 for exposing the keyhole 27 (see FIG. 1).
As shown in FIG. 2, a metal reinforcing frame 29 surrounding the window hole 16 is disposed on the back side of the door frame 15 over the entire periphery of the window hole 16.

  An upper cover plate 35 is mounted below the door frame 15. The upper cover plate 35 is cantilevered by a hinge fitting (not shown) with respect to the pachinko machine body 4 and can be opened and closed with respect to the pachinko machine body 4. The upper cover plate 35 is formed to project forward, and an upper tray 36 is placed on the upper surface. A lower cover plate 37 is disposed below the upper cover plate 35. The lower cover plate 37 is fixed to the pachinko machine body 4. The lower cover plate 37 is formed to protrude forward, and a lower tray 38 is placed on the upper surface. The lower tray 38 mainly stores game balls that could not be stored in the upper tray 36. An ashtray 40 is attached to the lower cover plate 37. An operation handle 39 is attached to the right side of the lower tray 38.

  As shown in FIGS. 4 and 5, the operation handle 39 includes a handle body 41 and a hemispherical grip portion 42 on which a palm is placed, and a rotating handle 43 is rotatable between the handle body 41 and the grip portion 42. It is arranged. The operation handle 39 is fixed to the lower cover plate 37 by a handle body 41. The handle main body 41 is formed with an operation switch 44 for controlling the single shot of a game ball. A decorative plating layer 45 is formed on the grip portion 42. As shown in FIG. 4, a variable resistor 47 is disposed on the front surface of the lower cover plate 37 surrounded by the handle body 41. The variable resistor 47 is connected to the rotation shaft 43 a of the rotation handle 43. The variable resistor 47 detects the amount of rotation of the rotation handle 43. Adjacent to the variable resistor 47, a capacitance detecting device 48 for detecting a change in the capacitance of the rotating handle 43 is provided. The capacitance detection device 48 detects whether or not the player touches the plated portion of the rotary handle 43.

As shown in FIG. 6, a ball feeding mechanism 55 is disposed on the back side of the upper cover plate 35. The ball feed mechanism 55 includes a standby passage 56, a game ball supply arm 57, and a ball feed solenoid 58 as main components. The standby passage 56, the ball feed solenoid 58, and the like are stored in the storage case 52. In the standby passage 56, the game balls supplied from the upper tray 36 of the upper cover plate 35 through the passage 51 are arranged in a line and wait. The game ball supply arm 57 is disposed on the side of the standby passage 56 (left side in FIG. 6), and is rotatable about a rotation shaft 59. The game ball supply arm 57 includes a holder 60 that holds only one game ball at the tip of the standby passage 56, and a cantilever 61 that is formed at a position facing the holder 60 across the rotation shaft 59. The ball feed solenoid 58 disposed above the cantilever 61 includes a rod 62 that appears and disappears by excitation and demagnetization.
As shown in FIG. 8, the pachinko machine body 4 facing the ball feed mechanism 55 is positioned at the position of the pachinko machine main body 4 (that is, the position facing the back surface of the upper cover plate 35). Rails 63 are provided.
In such a ball feeding mechanism 55, when the ball feeding solenoid 58 is excited and the rod 62 protrudes downward, the cantilever 61 is pushed, and the game ball supply arm 57 is moved upward with a rotation shaft 59 as shown in FIG. Swing in the direction. Then, the state-of-the-art game ball in the standby passage 56 is stored in the holder 60. Next, when the ball feed solenoid 58 is demagnetized, the holder 60 swings downward by its own weight, and sends the game ball stored in the holder 60 toward the launch position at the lower end of the launch rail 63.

  As shown in FIGS. 4 and 9, the game ball launching mechanism R is formed on an attachment base 64 attached to the pachinko machine body 4. A rotary solenoid 65 is disposed on the mounting base 64. A rotary shaft 66 of the rotary solenoid 65 projects from the back side of the mounting base 64, and a hammer 67 is fixed to the rotary shaft 66. A hard rubber head 67 a for repelling a game ball is attached to the tip of the hammer 67. A first buffer rubber 68 is disposed on the back side of the mounting base 64 and above the rotary solenoid 65, and a second buffer rubber 69 is disposed on the left side of the rotary solenoid 65. When the rotary solenoid 65 is in a demagnetized state, the hammer 67 falls down by its own weight and is placed on the second buffer rubber 69. On the other hand, when excited, it rotates in the direction of the first buffer rubber 68 (this direction is defined as a normal rotation direction), and abuts against the first buffer rubber 68 to restrict further rotation. As shown in FIGS. 3 and 4, a power supply control device 70 that controls power supply to the rotary solenoid 65 and the ball feed solenoid 58 is disposed behind the rotary solenoid 65.

Next, an electrical configuration of the pachinko machine configured as described above will be described.
As shown in FIG. 10, a read only memory (ROM) 71, a random access memory (RAM) 72, and a central processing unit (CPU) 73 are disposed in the control unit 32. The ROM 71 as the first main storage device stores in advance various control programs for the pachinko machine and further initial data for executing each program. The RAM 72 as the second main storage device temporarily stores new input data and the calculation result by the CPU 73. A variable resistor 47 and a capacitance detection device 48 are connected to the CPU 73, and a power supply control device 70 as a driver for driving the ball feed solenoid 58 and the rotary solenoid 65 is connected. The CPU 73 executes various arithmetic processes based on the programs and data in the ROM 71 and the RAM 72, the detection values of the variable resistor 47 and the capacitance detection device 48, and controls the ball feed solenoid 58 and the rotary solenoid 65. Further, a timer circuit 75 is connected to the CPU 73, and the timings of the ball feeding solenoid 58 and the rotary solenoid 65 are taken based on the timer circuit 75. The CPU 73 also controls the electromagnetic display, motor, etc. (not shown) of the variable display device 13, the ball payout mechanism P, and the safe ball processing mechanism Q, but the description thereof is omitted in this embodiment.

  Next, the operation timing of the ball feeding solenoid 58 and the rotary solenoid 65 and the actual operation of the hammer 67 will be described based on a first timing chart executed by the CPU 73 shown in FIG. The amplitude directions of the touch signal S1, the operation active signal S2, and the 0.6 second clock signal S3 indicate voltage values, and the amplitude directions of the ball feed solenoid 58 and the rotary solenoid 65 indicate current values. When the player touches the rotation handle 43 of the operation handle 39, the touch signal S1 rises at t1 based on the output from the capacitance detection device 48 and is turned on. At the same time, the operation active signal S2 rises and is turned on, and the weak brake current E is turned on with the rise of the operation active signal S2 as a trigger, so that the rotary solenoid 65 starts to be fed. The brake current E does not give the rotary solenoid 65 excitation enough to turn the hammer 67, but gives a constant positive torque to the hammer 67.

The 0.6 second clock signal S3 is a signal that is repeatedly output with a period of 0.6 seconds (actually, there is a slight difference in setting values depending on the model), and triggers the rise of the operation active signal S2 at t1. And rises after 0.3 seconds and is turned on. Then, in synchronization with this, the operating current to the ball feed solenoid 58 rises and turns on. That is, the first ball feed pulse a1 is input, the ball feed solenoid 58 is excited, the game ball supply arm 57 is swung as described above, and the game ball is sent in the direction of the hammer 67 of the rotary solenoid 65. The ball feed solenoid 58 falls at t3 and is turned off. Hereinafter, the operating current of the ball feed solenoid 58 rises in synchronization with the rise of the 0.6 second clock signal S3 (start of the ON state).
On the other hand, at t4 when 0.3 seconds have elapsed from t2, the 0.6 second clock signal S3 falls and is turned off. Thereafter, the 0.6 second clock signal S3 is repeatedly turned on and off in a cycle of 0.6 seconds. In synchronization with the fall of the 0.6 second clock signal S3, the operating current to the rotary solenoid 65 rises and turns on. That is, the first firing pulse b1 is input to the rotary solenoid 65, the hammer 67 rotates, and the game ball supplied from the game ball supply arm 57 is launched. Thus, there is a time lag in the drive start time of the ball feed solenoid 58 and the rotary solenoid 65 in consideration of the time from the game ball to the launch position of the hammer 67 from the game ball supply arm 57.
At this time, the CPU 73 determines the amplitude of the first firing pulse b1 based on the detection signal from the variable resistor 47. That is, if the player greatly rotates the rotation handle 43, a larger operating current is supplied to the rotary solenoid 65. Hereinafter, the operating current of the rotary solenoid 65 rises in synchronization with the fall of the 0.6 second clock signal S3 (start of the OFF state).
The first firing pulse b1 (same for the following firing pulses) is composed of a plurality of pulses having a very small pulse width in consideration of the ease of torque control of the rotary solenoid 65.

The hammer 67 excited by the operating current (first firing pulse b1) and rotated vigorously strikes the game ball and then bounces against the first shock absorbing rubber 68, and vigorously moves in the direction of the second shock absorbing rubber 69. It turns counterclockwise.
However, the weak brake current E is input to the rotary solenoid 65 again with the falling edge of t5 as a trigger (that is, at the same time as the first firing pulse b1 as the operating current is turned off). Accordingly, the hammer 67 that reversely rotates toward the second shock absorbing rubber 69 is given a positive torque by the brake current E, and a momentum that collides with the second shock absorbing rubber 69 due to a kind of braking effect. Is weakened. And even if the hammer 67 collides with the second buffer rubber 69, the bouncing converges quickly and disappears before the second firing pulse b2 is started.
Here, the momentum of the hammer 67 colliding with the second buffer rubber 69 is the maximum output from the capacitance detection device 48, that is, the state where the player has rotated the rotation handle 43 most. Therefore, the brake current E is set with reference to the bounce of the hammer 67 with respect to the second buffer rubber 69 in the maximum output state from the capacitance detection device 48.

The next operating current (second ball feed pulse a2) is output to the ball feed solenoid 58 in synchronization with the 0.6 second clock signal S3 which rises again at t6 and is turned on. That is, the ball feed solenoid 58 is excited again and the next game ball is sent in the direction of the hammer 67 of the rotary solenoid 65 in the same manner as described above. The second ball feed pulse a2 falls at t7 and is turned off.
At t8 when 0.3 seconds have elapsed from t6, the 0.6 second clock signal S3 falls again to turn off, and in synchronization with this, the second operating current (second firing pulse b2) is input to the rotary solenoid 65. Is done. That is, the hammer 67 rotates and the game ball supplied from the game ball supply arm 57 is launched. This operating current falls at t9 and is turned off. Since the weak brake current E is input again to the rotary solenoid 65 in synchronization with the fall of t9, the hammer 67 behaves in the same manner as the first launch.

At time t10 to t11, when the third operating current (third ball feed pulse a3) is input to the ball feed solenoid 58, the touch signal S1 falls because the player releases the operation handle 39 at t12. Turns off. That is, since the game has been stopped, it is necessary to stop the ball feeding and ball launching operations.
When the 0.6 second clock signal S3 falls again at t13 and is turned off, the third operating current (third firing pulse b3) is input to the rotary solenoid 65 at t13 to t14 in synchronization with this. That is, since the hammer 67 rotates and the game ball supplied from the game ball supply arm 57 is launched, no game ball remains at the launch position.

The operation active signal S2 is continued until the next rising edge (t15) of the 0.6 second clock signal S3 on condition that the touch signal S1 is turned off when the 0.6 second clock signal S3 is on. This is because the game ball is not left at the launch position as described above. Accordingly, when the touch signal S1 is turned off when the 0.6 second clock signal S3 is turned off, the next ball feed pulse is not output, and the operation active signal S2 immediately falls and turns off. As the operation active signal S2 is turned off, signal input to the ball feed solenoid 58 and the rotary solenoid 65 is eliminated.
If the player does not release the operation handle 39 at t12, the operation active signal S2 is kept on, so that the 0.6 second clock signal S3 also continues, and the ball feed solenoid 58 and the rotary solenoid 65 act. Game balls are continuously launched at intervals of 0.6 seconds.

With this configuration, the present embodiment has the following effects.
(1) When the firing pulse is output and the hammer 67 is rotated and returned to the reverse direction vigorously by the reaction that collides with the first shock absorbing rubber 68, the brake current E causes a positive torque in the positive rotation direction. Will be applied and a kind of brake will be applied. For this reason, the bounce on the second shock absorbing rubber 69 is suppressed, and the problem that the launch position is not stabilized and the speed of the hit ball is uneven is eliminated since the bounce is substantially settled until the next launch.
(2) Since the brake current E is based on the operating current (fire pulse) when the hammer 67 rotates most vigorously in the maximum output state from the capacitance detection device 48, the momentum of the hammer 67 is too strong. There will be no bounces before the next launch.
(3) Since the torque to the extent that the brake current E does not always rotate the hammer 67 is applied to the rotary solenoid 65 except when the firing pulse is output, the rotational speed of the hammer 67 when the firing pulse is output is braked. This is faster than when the current E is not applied, and a stronger launch of the game ball is possible.

  Next, the operation timing of the ball feeding solenoid 58 and the rotary solenoid 65 and the actual operation of the hammer 67 will be described based on a second timing chart executed by the CPU 73 shown in FIG. The amplitude directions of the touch signal S1, the operation active signal S2, and the 0.6 second clock signal S3 indicate voltage values, and the amplitude directions of the ball feed solenoid 58 and the rotary solenoid 65 indicate current values. When the player touches the rotation handle 43 of the operation handle 39, the touch signal S1 rises at t1 based on the output from the capacitance detection device 48 and is turned on. At the same time, the operation active signal S2 rises and is turned on.

The 0.6 second clock signal S3 is a signal that is repeatedly output with a period of 0.6 seconds (actually, there is a slight difference in setting values depending on the model), and triggers the rise of the operation active signal S2 at t1. And rises after 0.3 seconds and is turned on. Then, in synchronization with this, the operating current to the ball feed solenoid 58 rises and turns on. That is, the first ball feed pulse a1 is input, the ball feed solenoid 58 is excited, the game ball supply arm 57 is swung as described above, and the game ball is sent in the direction of the hammer 67 of the rotary solenoid 65. The ball feed solenoid 58 falls at t3 and is turned off. Hereinafter, the operating current of the ball feed solenoid 58 rises in synchronization with the rise of the 0.6 second clock signal S3 (start of the ON state).
On the other hand, at t4 when 0.3 seconds have elapsed from t2, the 0.6 second clock signal S3 falls and is turned off. Thereafter, the 0.6 second clock signal S3 is repeatedly turned on and off in a cycle of 0.6 seconds. In synchronization with the fall of the 0.6 second clock signal S3, the operating current to the rotary solenoid 65 rises and turns on. That is, the first firing pulse b1 is input to the rotary solenoid 65, the hammer 67 rotates, and the game ball supplied from the game ball supply arm 57 is launched. Thus, there is a time lag in the drive start time of the ball feed solenoid 58 and the rotary solenoid 65 in consideration of the time from the game ball to the launch position of the hammer 67 from the game ball supply arm 57.
At this time, the CPU 73 determines the amplitude of the first firing pulse b1 based on the detection signal from the variable resistor 47. That is, if the player greatly rotates the rotation handle 43, a larger operating current is supplied to the rotary solenoid 65. Hereinafter, the operating current of the rotary solenoid 65 rises in synchronization with the fall of the 0.6 second clock signal S3 (start of the OFF state).
The first firing pulse b1 (same for the following firing pulses) is composed of a plurality of pulses having a very small pulse width in consideration of the ease of torque control of the rotary solenoid 65.

The hammer 67 excited by the operating current (first firing pulse b1) and rotated vigorously strikes the game ball and then bounces against the first shock absorbing rubber 68, and vigorously moves in the direction of the second shock absorbing rubber 69. It turns counterclockwise.
However, the first sub-pulse P-S1 is input with an extremely short pulse width 0.1 seconds later using the falling edge of t5 as a trigger (that is, at the same time as the first emission pulse b1 as the operating current is turned off). Subsequently, the second sub-pulse P-S2 is input after 0.2 seconds with the same pulse width, and the third sub-pulse P-S3 is input with the very short pulse width after 0.3 seconds with the same pulse width. The amplitude of the first sub-pulse P-S1 is made equal to the maximum amplitude, the amplitude of the second sub-pulse P-S2 is 50% of the amplitude of the first sub-pulse P-S1, and the third sub-pulse P-S3 Is set to 30 percent.
Accordingly, the hammer 67 that reversely rotates toward the second shock absorbing rubber 69 is given a torque in the forward direction by the series of sub-pulses P-S1 to S3, and a kind of braking effect is exerted to act as the second shock absorbing rubber. The momentum of hitting 69 is weakened. And even if the hammer 67 collides with the second buffer rubber 69, the bouncing converges quickly and disappears before the second firing pulse b2 is started.
Here, the momentum of the hammer 67 colliding with the second buffer rubber 69 is the maximum output from the capacitance detection device 48, that is, the state where the player has rotated the rotation handle 43 most. Accordingly, the amplitude and interval of the sub-pulses P-S1 to S3 are set based on the bounce of the hammer 67 with respect to the second buffer rubber 69 in the maximum output state from the capacitance detection device 48.

The next operating current (second ball feed pulse a2) is output to the ball feed solenoid 58 in synchronization with the 0.6 second clock signal S3 which rises again at t6 and is turned on. That is, the ball feed solenoid 58 is excited again and the next game ball is sent in the direction of the hammer 67 of the rotary solenoid 65 in the same manner as described above. The second ball feed pulse a2 falls at t7 and is turned off.
At t8 when 0.3 seconds have elapsed from t6, the 0.6 second clock signal S3 falls again and is turned off, and in synchronization with this, the second operating current (second firing pulse b2) is output to the rotary solenoid 65. Is done. That is, the hammer 67 rotates and the game ball supplied from the game ball supply arm 57 is launched. This operating current falls at t9 and is turned off. Since the series of sub-pulses P-S1 to S3 are inputted again to the rotary solenoid 65 in synchronization with the fall of t9, the hammer 67 behaves in the same manner as the first firing.

At the stage when the third operating current (third ball feed pulse a3) is output to the ball feed solenoid 58 at t10 to t11, the touch signal S1 falls because the player has released his hand from the operation handle 39 at t12. Turns off. That is, since the game has been stopped, it is necessary to stop the ball feeding and ball launching operations.
When the 0.6 second clock signal S3 falls again at t13 and is turned off, the third operating current (third firing pulse b3) is output to the rotary solenoid 65 at t13 to t14 in synchronization with this. That is, since the hammer 67 rotates and the game ball supplied from the game ball supply arm 57 is launched, no game ball remains at the launch position.

The operation active signal S2 is continued until the next rise (t15) of the 0.6 second clock signal S3 as a condition that the touch signal S1 is turned off when the 0.6 second clock signal S3 is on. This is because the game ball is not left at the launch position as described above. Therefore, when the touch signal S1 is turned off when the 0.6 second clock signal S3 is turned off, the next ball feed pulse is not output, so that the operation active signal S2 falls immediately and turns off. As the operation active signal S2 is turned off, signal input to the ball feed solenoid 58 and the rotary solenoid 65 is eliminated.
Further, the first sub-pulse P-S1 and the second sub-pulse P-S2 are input to the rotary solenoid 65 from t14 to t15. These sub-pulses are essentially unnecessary because there is essentially no next game ball, but they remain because these sub-pulses are input triggered by the falling edge of the firing pulse.
If the player does not release the operation handle 39 at t12, the operation active signal S2 is kept on, so that the 0.6 second clock signal S3 also continues, and the ball feed solenoid 58 and the rotary solenoid 65 act. Game balls are continuously launched at intervals of 0.6 seconds.

With this configuration, the present embodiment has the following effects.
(1) When the firing pulse is output and the hammer 67 is rotated and returned to the reverse direction vigorously in response to the collision with the first shock absorbing rubber 68, the first to third sub-pulses P-S1 to S3 are returned. Thus, a positive torque in the positive rotation direction is applied, and a kind of brake is applied. For this reason, the bounce on the second shock absorbing rubber 69 is suppressed, and the problem that the launch position is not stabilized and the speed of the hit ball is uneven is eliminated since the bounce is substantially settled until the next launch.

It should be noted that the present invention can be modified and embodied as follows.
In the second timing chart shown in FIG. 12, a total of three pulses of the first to third sub-pulses P-S1 to S3 are input to the rotary solenoid 65, but this may be one or two There may be four or more.
The amplitudes of the first to third sub-pulses P-S1 to S3 are gradually reduced, but they may be the same size.
The magnitude of the amplitude of the brake current E and the first to third sub-pulses P-S1 to S3 (that is, the current supply amount) can of course be changed. In this case, for example, a variable resistor (volume) may be provided on the mounting base 64 as an adjustment mechanism along with the rotary solenoid 65.
The rotary solenoid 65 of the above-mentioned hitting ball launching device has a configuration in which a hammer 67 in the initial position is rotated to launch a game ball.
