The front door 21 is attached to the window frame 13 of the front frame 11 so that the front door 21 can be opened and closed. A glass window 22 through which the game board 14 is seen is formed, and the game balls placed in the upper ball plate 24 are fed one by one to a launch rail 35 provided below the game board 14 by a ball feeder 25, The lever 33 of the operation portion 32 provided below the front surface of the front frame 11 is rotated by a predetermined angle so that a launch ball can be launched.

The ball launching device for launching this game ball is provided on the launcher 34, and normally the lever 33 of the operating portion 32 is biased counterclockwise by the elastic body so that the operating portion 32 can be grasped lightly. When the lever 33 is rotated clockwise against the force of the elastic body, the detection switch such as a limit switch is turned on, the motor starts rotating, and the hammer 51 moves it to a predetermined position on the firing rail 35. The sent game ball is launched, and the structure of the main part thereof is generally fixed to the rotation shaft 42 of the motor 41 and rotates with the rotation of the motor 41 as shown in FIG. A cam 43 having a crescent shape or the like is provided, and a pin 53 for abutting against the cam 43 and rotating the hammer 51 according to the rotation of the cam 43 to rotate the hammer 51 is used. Is provided on the rotary shaft 42 of the motor 41.
When the cam 43 rotates to a predetermined angle due to the displacement of the rotation shaft 52 of the hammer 51, the cam 43 is disengaged from the pin 53, and when the cam 43 is disengaged from the pin 53, the hammer 51 is returned. It is decided to return the hammer 51 to a position where it is vigorously returned by the spring 54 and the rear end of the hammer 51 hits the stopper 57 and is stopped, and thus when the hammer 51 returns to the original position, the predetermined position of the firing rail 35. It is launched by hitting the game ball placed in the with a spring 58 provided at the tip of the hammer 51.

One end 55 of the return spring 54 is hammered.
The other end 56 is fixed to a disc-shaped strength adjuster 61, and the strength adjuster 61 is rotatable around a rotation shaft 52 of the hammer 51 and meshes with the surroundings. Has a portion and meshes with an adjustment connection gear 62 that rotates together with the lever 33 of the operation portion 32. Therefore, when the lever 33 is rotated slightly clockwise, a detection switch (not shown) is activated and the motor 41
When the cam 43 comes into contact with the pin 53, the pin 53 and the hammer 51 start rotating around the rotating shaft 52 against the return spring 54, and when the cam 43 is disengaged from the pin 53, The hammer 51 returns by the force of the return spring 54, the game ball is launched by the spring 58 provided at the tip of the hammer 51, and the adjustment connection gear 62 rotates by the rotation amount of the lever 33 and meshes with this adjustment connection gear 62. The amount of rotation of the strength adjuster 61 is determined, and the return spring 54
By adjusting the return force of the game ball, the firing speed of the game ball is determined.

A foul ball return path 36 is provided between the launch rail 35 and the guide rail 15 to return the game balls not hit from the guide rail 15 to the surface of the game board 14 to the lower ball plate 31. I am trying.

[0006]

In a launching device for launching a game ball with a hammer provided with a spring at the tip as described above, if the center of the spring is not properly hit at the center of the game ball, the way the game ball flies Will be disturbed,
Hammer adjustment is necessary to prevent such disorder, and the center of the spring is also displaced due to precision and assembly error of parts of the launcher, so it is often necessary to adjust the hammer tip. As this hammer adjustment, delicate adjustment is required, and since this adjustment is a difficult task that requires skill, there is a drawback that it requires time and labor.

[0007] Further, since the impact when the game ball is fired is repeatedly applied to the hammer, the deterioration of the parts is severe, and further, if dust or the like adheres to the movable part, the return of the hammer is not constant and the game is played. In order to properly launch the ball at a predetermined speed, maintenance such as cleaning is often required, and there is a drawback that it requires labor.

[0008]

According to the present invention, a large number of electromagnets are arranged side by side along a firing rail, and a current is sequentially passed through the large number of electromagnets. Excited in order from the electromagnet placed below
Game balls are sequentially attracted and accelerated by the excited electromagnet so that they are launched from the launch rail.

[0009]

[Operation] According to the present invention, a game ball placed on the launch rail can be attracted and moved by sequentially exciting a current through a large number of electromagnets arranged along the launch rail. Then, by switching the electromagnet to be excited in order, the game ball is moved along the launch rail while sequentially attracting it so that it approaches the excited magnet, and the game ball is excited at high speed by exciting the lowest electromagnet in order in a short time. You can move the game ball from the launch rail.

EXAMPLE As shown in FIG. 1, the embodiment of the ball launching device according to the present invention is that 24 electromagnets 111 to 134 are arranged along the launching rail 35 and below the launching rail 35, and a microcomputer 71 Based on the output of (hereinafter simply referred to as "microcomputer 71"), 24 input / output interfaces 75 output 24 control signals, and by inputting these control signals into the switch circuit 80, 24 switch elements 81-104 are incorporated. The 24 electromagnets 111 to 134 arranged so as to be lined up along the firing rail 35 are sequentially excited from the first electromagnet 111 by sequentially connecting the switch elements of the switch circuit 80.

The input / output interface 75 outputs a first control signal of H level to the A1 signal from the first output terminal when an 8-bit specific signal is input from the microcomputer 71,
When the other specific signal of the bit is input from the microcomputer 71, the second control signal of the H level is output to the A2 signal from the second output terminal, so that the first output terminal to the twenty-fourth output terminal are output depending on the content of the specific signal. It outputs the control signal of H level from either one.

Then, the microcomputer 71 outputs a specific signal for sequentially outputting a control signal from the first output terminal of the input / output interface 75 to the second output terminal according to the program, and outputs 24 kinds of specific signals. It is sent to the input / output interface 75 in a short time of about 0.1 second, and as shown in FIG.
It outputs up to the 24th control signal output to 4 signals in order, and switches each control signal to A1 while advancing the switching timing so as to sequentially shorten the output time of each control signal.
It is assumed that the signals are continuously output from the A24 signal.

Further, the switch circuit 80 to which each control signal from the A1 signal to the A24 signal is input uses 24 non-contact switches such as switching transistors, and as shown in FIG. Switch element
The control terminals 81 to 104 are connected to each other so that the first switch element 81 becomes conductive when the first control signal is input and the second switch element 82 becomes conductive when the second control signal is input. It is assumed that each of the 24 switch elements 81 to 104 is made conductive by each control signal.
The first switching element 81 is inserted between the power source and the first electromagnet 111 in series with the first electromagnet 111, and the second switching element 8
2 is in series with the second electromagnet 112, and the third switching element 83 is the third
Each switching element 8 so that it is connected in series with the electromagnet 113.
1 to 104 are connected in series with each electromagnet 111 to 134.

Therefore, in this embodiment, the first control signal to the 24th control signal are sequentially output from the input / output interface 75 by the specific signal from the microcomputer 71, and each control is output from the A1 signal to the A24 signal. The first switching element 81 to the 24th switching element 104 are sequentially conducted by the signal to excite the first electromagnet 111 to the 24th electromagnet 134, and the first electromagnet 111 to the 24th electromagnet 134 are placed on the launch rail 35. The played game balls can be sequentially sucked and moved.

In FIG. 3, a diode circuit 140 having 24 diodes in parallel with the electromagnets 111 to 134 is
Each diode is used as a freewheel diode, and when the excitation of each electromagnet 111-134 is stopped, the counter electromotive force generated in the electromagnet 111-134 is consumed. Then, the electromagnets 111 to 134 are arranged at equal intervals of 1 cm or the like, and as described above, the switching timing of each control signal output from the A1 signal to the A24 signal is sequentially advanced,
The microcomputer 71 sends 24 types of specific signals in about 80 milliseconds.
When output from, the game ball can be fired at a speed of about 5 to 6 meters per second.

Further, in the above embodiment, the electromagnets 111 to 134 are arranged at equal intervals, and the first control signal to the 24th control signal based on the specific signal are provided.
Although the control signal switching timing is sequentially advanced to shorten the duration of the control signal to be H level, the duration of each control signal is the same, and the first electromagnet 111 and the second electromagnet 1
By gradually widening the intervals of the electromagnets 111 to 134 so that the interval between the 23rd electromagnet 133 and the 24th electromagnet 134 is wider than the interval of 12, it is possible to accelerate the game ball in accordance with the moving speed of the game ball. Sometimes

Then, when controlling the firing speed of the game ball, the rotation angle of the lever 33 is detected by an angle detector such as a rotary encoder, and when the rotation angle of the lever 33 is maximum, as described above, there are 24 types. Even if a specific signal is output to excite all 24 electromagnets 111 to 134, when the rotation angle of the lever 33 is small, the output of the specific signal is cut off and excited so that the number of output of the specific signal is reduced. If the electromagnets are sequentially excited from the first electromagnet 111, the number of electromagnets to be excited is reduced, and the number of electromagnets to be excited among the electromagnets 111 to 134 is increased in accordance with an increase in the rotation angle of the lever 33. , The speed of the game ball can be increased according to the rotation angle of the lever 33.

It is needless to say that the number of electromagnets is not limited to 24, and the number of switch elements and free wheel diodes may be appropriately adjusted to the number of electromagnets. In this way, in this embodiment, a large number of electromagnets 111 to 134 arranged so as to be lined up along the launch rail 35 are sequentially excited and accelerated by the attractive force of each electromagnet 111 to 134, thereby launching a game ball. Since it is a thing, it is possible to shoot a game ball without holding a hammer 51, and to simplify maintenance such as cleaning with a simple mechanical structure.
