Outside the turntable 4 of the cabinet 1, there are four catcher arms 6 which are driven by respective driving mechanisms as shown in FIGS.

3 to 6 are diagrams showing the configuration of each part of the embodiment of the crane game device according to the present invention, in which FIG. 3 shows the catcher arm drive mechanism, FIG. 4 shows the catcher drive mechanism, and FIG. This figure is a perspective view showing the ball chain loosening detection mechanism, and FIG. 6 is a perspective view showing the catch mechanism.

A catch arm turning mechanism 31 is provided on the bottom plate of the cabinet 1.

A motor 33 for rotating the arm 6 is installed in the frame 32. The output shaft of the motor 33 is connected via a reduction gear train 34 to
The rotating shaft 35 is rotated. This rotating shaft 35 has
A disc 35a with a cam is provided to turn the limit switches LS1 and LS2 on and off according to the rotation angle. The limit switch LS1 is a switch for detecting that the catch arm 6 is in the standby position. The limit switch LS2 is
This is a switch for detecting the end (prize acquisition position) when the catcher arm 6 moves towards the center of the prize stand of the turntable 3.

A catcher lifting mechanism 36 is provided above the catcher arm rotating mechanism 31.

Inside the frame 37, there is a first
A pulley 41 and a second pulley 45 are rotatably attached.

A pin 41a is implanted on one side of the first pulley 41, and a gear 42 is coaxially provided on the other side, and a pinion gear 42a of the output shaft of the motor 43 meshes with this gear 42. There is.

The second pulley 45 is provided coaxially with the shaft 44 of the first pulley 41, and is provided with a long hole 45a into which the pin 41a is loosely fitted. Therefore, the first pulley 41 rotates differentially with respect to the second pulley 45 by the length of the elongated hole 45a at the beginning when the motor 43 starts forward and reverse rotation, and thereafter rotates integrally. become.

The second pulley 45 is provided with a cam surface 46, and this cam surface 46 turns on and off the limit switches LS3 and LS4 shown in FIG. 3b. The limit switch LS3 is a switch for detecting the position when the catcher 7 returns to the top. The limit switch LS4 is a switch for detecting that the catcher 7 has reached the prize table of the turntable 3.

A gear 47 is provided on the second pulley 45, and a brake mechanism 48 meshes with this gear 47. The brake mechanism 48 is connected to the catcher 7
Due to the weight of the second pulley 45, a braking force is applied to the extent that the second pulley 45 is not rotated. This is the first pulley 4
This is because the second pulley 45 is stopped at the beginning of the first rotation, and only the first pulley 41 rotates by the length of the elongated hole 45a to open the pawl 73 of the catcher 7. This is to prevent the claws 72 from turning together and making it impossible to open the claws 72.

A first ball chain 51 and a second ball chain 52 are hung on the first pulley 41 and the second pulley 45, respectively.

Above these pulleys 41, 45, there is a ball chain slack detection mechanism 53 as shown in FIG.
is provided.

The detection arm 54 is rotatably provided around a shaft 55, and is biased clockwise in FIG. 5 by a spring 56. A guide wheel 57 is provided on this arm 54, and each ball chain 51,
52 is multiplied. A cam 58 is provided coaxially with the guide wheel 57. This cam 58 turns the limit switch LS5 on and off. The limit switch LS5 allows the ball chains 51 and 52 to loosen before the catcher 7 reaches the prize stand.
This is a switch that detects that the detection arm 54 is activated. When prize 5 is exciting,
Before Catcher 7 reaches the prize stand, Prize 5
At this point, the catcher 7 needs to close the claw 73. At this time, the ball chains 51 and 52 hit the prize 5 and loosen, so this is detected and the timing for closing the claw 73 is obtained.

As shown in FIG. 6, a guide wheel 61 is provided at the tip of the catch arm 6, and each ball chain 51, 52 hung on this guide wheel 61.
A catcher 7 is attached to the tip. The ball chain 52 is attached to a cylindrical catch frame 71, and the ball chain 51 is attached to a weight 72 movably provided within the catcher frame 71. Three claws 73 are rotatably provided at the lower end of the weight 72, and the middle of the claws 73 and the catch frame 7
The outer walls of 1 are connected by links 74. Therefore, if only the ball chain 51 loosens, the weight 71
is lowered by its own weight, and the claw 73 opens.

Next, the operation of the crane game device according to the present invention will be explained.

The turntable 3 is always rotated in a constant direction at a low speed by the rotation of the motor 25.

When a coin is inserted into the coin slot 8c, the push button 8a shown in FIG. 1 flashes. When the push button 8a is pressed, the push button 8a changes from flashing to lit, and the motor 33 rotates. When the catcher arm 6 moves toward the center of the prize stand on the turntable 3 and releases the push button 8a, the lamp disappears and the catcher arm 6 moves toward the center of the prize stand on the turntable 3.
stops.

Next, the push button 8b starts blinking. In this state, when the push button 8b is pressed and released, the lamp goes out, the motor 43 rotates, and only the first pulley 41 rotates by the length of the elongated hole 45a.
Therefore, only the first ball chain 51 becomes loose,
As shown in FIG. 6, the weight 72 of the catcher 7
lowers and the claw 73 opens.

The first pulley 41 further rotates, and the pin 41a
When the second pulley 4 comes into contact with one end of the elongated hole 45a, the second pulley 4
5 starts rotating together, and the second ball chain 5
2 loosens, so the catcher 7 descends.

When the catcher 7 reaches the top of the prize stand, the cam 46 of the second pulley 45 operates the limit switch LS4, causing the motor 43 to rotate in reverse.

When the motor 43 reverses, only the first pulley 41 rotates in reverse by the length of the elongated hole 45a, closing the claw 73 of the catcher 7. At this time, if the prize 5 is in that position, the prize 5 can be grabbed with the claw 73.

The first pulley 41 further rotates, and the pin 41a
comes into contact with the other end of the long hole 45a, the second pulley 4
5 starts rotating together, and the second ball chain 5
2 and raise the catcher 7.
The cam 46 of the second pulley 45 is the limit switch.
When LS3 is activated, motor 43 stops and
Catcher 7 stops rising.

At the same time, the motor 33 rotates in reverse, and the catch arm 6 returns to its original position. This position is the position of the prize opening 3b of the turntable 3. At this position, the motor 43 rotates normally, only the first pulley 41 rotates, and the claw 73 is opened to drop the prize 5.

If the prize opening 3b is exactly where the prize 5 falls, the prize 5 can be obtained from the prize takeout opening 9 through the prize chute 9a. If the place where it fell is the slope 3a, the prize 5 will return to the original prize stand.

Note that when a large amount of prizes 5 are on the prize table, the claw 72 of the catcher 7 may hit the prizes 5 before reaching the prize table of the turntable 3.
Despite the rotation of each pulley 41, 42, the ball chains 51, 52 become loose. Therefore, the detection arm 54 shown in FIG. 5 is biased by the spring 56 and rotates clockwise, and the cam 58 closes the limit switch LS5. This signal causes the motor 43 to rotate in the reverse direction, causing the first pulley 41 to rotate in the reverse direction. Therefore, similarly to the above, the claw 73 of the catcher 7
At the same time, the catcher 7 is raised.

Without being limited to the embodiments described above,
Various modifications can be made.

Although a ball chain is shown as an example, other strings may be used.

Also, the explanation was given using an example in which the catcher moves up and the catcher arm immediately returns to its original position.
When it rises, press button 8b to blink,
If the catcher arm returns to its original position after pressing the push button 8b, it will be easier to aim at the prize opening of the turntable, so by timing it well, it will be easier to obtain the prize.

[Effect of idea]

As explained in detail above, according to the present invention,
Even if the jackpot grabs the prize, depending on the timing of the drop, it may not go into the prize slot and return to the prize stand, so in addition to game technique, the element of timing due to luck or bad luck comes into play, making crane games even more fun. can do.
