Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crane game machine, and more particularly to a technique for improving an arm for holding a prize.

[0002]

2. Description of the Related Art Conventionally, a crane game machine is widely known as a prize acquisition game. This crane game machine moves a gripping pawl device to a position above a target prize in a case where a plurality of prizes are arranged, and then lowers the gripping pawl device to grip the prize by a claw member of the grip pawl device. Then, it is raised and the gripped prize is carried to the outlet to win the prize. For example, the actual fair 7-
In the crane game described in Japanese Patent No. 36707, a guide rail arranged at an upper part of a housing is movably supported in a horizontal plane, and a carrier slidably mounted on the guide rail is vertically moved via a telescopic tube. An operably supported gripper device is connected. The gripper device is provided with a pair of claw members each having an upper end supported so as to be openable and closable, and each claw member is biased in the closing direction via a spring. Then, the claw member is opened against the spring through the drive device and then lowered, and when the claw member is released by the drive device after reaching the prize or the floor, the claw member is closed by the spring. Holds the prize.

[0003]

However, in the above-mentioned prior art, when the grasping pawl device is stopped above the prize, it is only interesting to see the specified amount of the pawl member open and close, so that it is not interesting. At the same time, there is a problem in that it is not possible to position the claw member at a position intended by the player, so that a satisfactory feeling cannot be obtained. In other words, the position of the claw member with respect to the prize is determined when the gripper device is stopped above the prize, and the player cannot freely set the position of the claw member with respect to the prize. If there is a prize at a position that interferes with the rotation trajectory of the claw member,
You can't win a prize. Therefore, according to the present invention, since the arm for holding the prize can be positioned at the place intended by the player without being affected by the rotation trajectory, the prize cannot be obtained not only when the prize can be acquired. Even in such a case, the player can fully understand the situation and provide a crane game machine with which the player can be satisfied.

[0004]

In order to solve the above-mentioned problems, the invention described in claim 1 has two arms (movably provided along a rail (for example, the rail 12 in the embodiment)). For example, the arm 9 in the embodiment)
After lowering these arm positions and lowering these arms, both arms are moved inward to grip the prize. With this configuration, each arm that descends between the prizes moves inward to sandwich the prize, and a desired prize can be gripped.

The invention described in claim 2 is characterized in that the moving amount of the arm is determined based on preset data when the arm is moved inward. With this configuration, the success rate of the game can be controlled to some extent on the device side, and the player side can select the prize in consideration of the movement amount of the arm. It should be noted that it is preferable to provide a display means for visually indicating to the player the amount of movement of the arm inward.

The invention described in claim 3 is characterized in that the data is set by a random number. By constructing in this way, the element of contingency is greatly affected,
We can provide games that you will never get tired of.

According to a fourth aspect of the present invention, the arm is swingably provided outside. With this configuration, the movement of the arm to the inside does not grip or damage the prize too strongly, and the amount of movement of the arm to the inside of the device and the swing of the arm to the outside are prevented. By combining with, you can control the success rate of the game freely. An adjusting member such as a spring may be provided so that the amount and strength of arm swing can be adjusted.

According to a fifth aspect of the present invention, when the arm is moved inward, the arm is moved by a pressure sensor (for example, the pressure sensor SEN8 in the embodiment) provided on the arm until a predetermined pressing force is reached. It is characterized by With such a configuration, it is possible to reliably grasp the gripping state of the premium, which largely influences whether or not the premium can be gripped.

Next, the operation of the crane game machine will be described with reference to the flow charts of FIGS. Here, as described above, when a coin is inserted from the coin insertion slot 5 of the housing 1, the moving range of the arm 9, that is, the position of the arm 9 is determined by the LED lamp 15, and after the arm 9 descends, To what position the arm 9 moves inward to grab the prize is determined. Step S0
In 1, it is determined whether or not the forward switch SW1 has been pressed. If the determination result is "YES", the process proceeds to step S02, and if the determination result is "NO", the process of step S01 is repeated. In step S02,
The stepping motor M1 is rotated to move the gripping device 10 to the inner side, and the process proceeds to step S03. In step S03, it is determined whether the forward switch SW1 is released or the optical sensor SEN2 detects. If the determination result is “YES”, the process proceeds to step S04, and if the determination result is “NO”, the process of step S03 is repeated.

In step S04, the stepping motor M1 is stopped and the process proceeds to step S05. Step S05
At, it is determined whether or not the left arm switch SW2 has been pressed. If the determination result is “YES”, the process proceeds to step S06, and if the determination result is “NO”, the process of step S05 is repeated. In step S06,
The stepping motor M3 is rotated to move the left arm 9a to the right, and the process proceeds to step S07. In step S07, it is determined whether the left arm switch SW2 has been released or the proximity sensor SEN5 has detected.
If the determination result is “YES”, the process proceeds to step S08, and if the determination result is “NO”, the process of step S07 is repeated. As a result, the left arm 9a that has moved to the right can be stopped between the prize intended by the player.

In step S08, the stepping motor M3 is stopped and the process proceeds to step S09. In step S09, it is determined whether the right arm switch SW3 has been pressed. If the determination result is “YES”, the process proceeds to step S10, and if the determination result is “NO”, the process of step S09 is repeated. Step S10
Now, rotate the stepping motor M4 to move the right arm 9
Move b to the left and proceed to step S11. Step S11
In, whether the switch SW3 for the right arm is released,
Alternatively, it is determined whether or not the proximity sensor SEN5 has detected. If the determination result is “YES”, step S12
Proceed to step S1 if the determination result is “NO”
The process 1 is repeated. As a result, the right arm 9b that has moved to the left can be stopped between the prize intended by the player and the prize.

In step S12, the stepping motor M4 is stopped to determine the descending position of both arms 9, the stepping motor M2 is rotated, the gripping device 10 is lowered (moved downward), and the process proceeds to step S13. By this operation, the two arms 9a and 9b are placed at the place intended by the player.
Will fall. Therefore, the arm 9 can be reliably inserted between the prizes. In step S13, it is determined whether any of the microswitches MS1 to MS6 is detected. If the determination result is “YES”, the process proceeds to step S14, and if the determination result is “NO”, the process of step S13 is repeated. In step S14, the stepping motor M2 is stopped and the stepping motor M3 and the stepping motor M4 are rotated to rotate the arm 9
The operation of gripping the prize with the claw 13 is performed. Specifically, both arms 9 are moved inward.

For example, when the arm 9 descends to the proper position, the microswitches MS1 and MS2 move to the sensor rod 3
Since it comes into contact with the floor surface 8 due to 5, the stepping motor M2 can be stopped by using this as a machine to start the operation of holding the prize by the arm 9. On the other hand, when the sensor rod 35 collides with the prize when the arm 9 descends, it means that the arm 9 has not descended to the proper position between the prizes, and at that time, the stepping motor By stopping M2 and starting the next ascending operation, it is possible to prevent the prize from being damaged and prevent the device from being overloaded. on the other hand,
When detected by the microswitches MS3 to MS6,
For example, when the prize collides with the lower end of the arm 9 and the prize does not collide with the sensor rod 35, or a large prize hits a part of the rail 12 (see, for example, FIGS. 9 and 11). There are cases. Even in such a case, the stepping motor M2 can be stopped in order to protect the prize, and the prize can be prevented from being damaged. Further, similarly to the above, it is possible to prevent the device from being overloaded.

In the next step S15, it is determined whether the arm 9 has moved by the set amount or the proximity sensor SEN5 has been detected. If the determination result is “YES”, the process proceeds to step S16, and if the determination result is “NO”, the process of step S15 is repeated. At this time, the arm 9 pivots around the pin 28, but the arm spring 9 clamps the prize by the elastic force adjusted by the wing nut 32 by the coil spring 31, so that the arm 9 can be elastically clamped without damaging the prize.

Here, the arm 9 operates so as to move by a set amount in order to grab a prize, but the moving amount of the arm 9 is set by the LED lamp 15 and this is given to the player in advance. Instead of the display mode, the following modes can be adopted. For example, the arm 9 is pinched for a certain period of time such as 0.5 seconds,
By utilizing the characteristics of the stepping motor M3 and the stepping motor M4, it is possible to continue the operation sandwiched by the number of pulses such as 100 pulses on the program.

As an application example of the setting based on the number of pulses, setting based on the moving distance is also possible. In this case, the movement distance of the arm 9 when one pulse is output is calculated from the step angle of one pulse of the stepping motor M3 and the stepping motor M4, the gear ratio, and the like, and based on that, an operation of sandwiching only 2 cm, for example. Can continue. Here, in this case, the display by the LED lamp 15 can be used together.

Further, as shown by a chain line in FIG. 6, a pressure sensor SEN8 is provided on the arm 9 and can be used as an input device. That is, the claw 13 or the arm 9 and the claw 13
The pressure sensor SEN8 is added to the portion for holding the prize, such as between the two, as an input device.
It is also possible to detect the pressing force of the prize by EN8 and continue the pinching operation until the pressing force reaches a predetermined value. As described above, by providing the pressure sensor SEN8, it is possible to surely grasp the gripping state of the prize, which largely influences whether or not the prize can be gripped, and increase the degree of freedom in various settings of the crane game machine such as the prize acquisition rate. At the same time, the player's gripping feeling can be set as desired.

In step S16, the stepping motor M3 and the stepping motor M4 are stopped, the stepping motor M2 is rotated, the gripping device 10 is raised (moved upward), and the process proceeds to step S17. Thereby, the prize held by the arm 9 can be moved upward.
In step S17, it is determined whether or not the microswitch MS7 has detected. That is, the micro switch M
In S7, it is detected whether the telescopic tube 16 has reached the upper limit position. If the determination result is “YES”, the process proceeds to step S18, and if the determination result is “NO”, the process of step S17 is repeated. In step S18, the stepping motor M2 is stopped and the stepping motor M2 is stopped.
1 is rotated to move the gripping device 10 to the front, and the process proceeds to step S19. In step S19, the optical sensor S
It is determined whether EN1 is detected. That is, the optical sensor SEN1 detects whether or not the gripping device 10 has reached the front limit position. If the determination result is “YES”, the process proceeds to step S20, and if the determination result is “NO”, the process of step S19 is repeated.

In step S20, the stepping motor M1 is stopped, the stepping motor M3 and the stepping motor M4 are rotated, the arm 9 is expanded, and the process proceeds to step S21. As a result, the outlet 1
The prize drops to 1 and moves to the prize outlet 4. In step S21, it is determined whether or not the optical sensors SEN3 and SEN4 have detected. If the determination result is “YES”, the process proceeds to step S22, and if the determination result is “NO”, the process of step S21 is repeated. Step S2
2 for stepping motor M3, stepping motor M4
Stop and return to the start. By this operation, the gripping device 10 and the arm 9 take the initial posture.

FIG. 24 is a flow chart corresponding to FIG. 23 when the prize outlet is small. That is, as shown in FIG.
21 is formed over the width direction of the gripping device 10, if the arm 9 is returned to the initial position when the prize is successfully gripped as shown in FIGS. Even if the prize is held at the position, the prize can be dropped into the outlet 11 by releasing the prize. However, as shown in FIG. 26, the outlet formed in a part of the gripping device 10 in the width direction is opened. In the case of 11A, when moving the gripping device 10 to the initial position, the arm 9 holding the prize must be moved with respect to the rail 12. The flowchart shown in FIG. 25 will be described below.
Since the processing shown in FIGS. 21 and 22 is the same, a part of it is used and the description thereof is omitted.

If the determination result in step S17 of FIG. 22 is "YES", the flow proceeds to step S30, where the stepping motor M1 is stopped and the stepping motor M3 and the stepping motor M4 are rotated to rotate the arm 9
Is moved to the left while maintaining the width of, and the process proceeds to step S31.
As a result, the outlet 1 which is smaller than that of the above-described embodiment is provided.
You can move the prize towards 1A. In step S31, it is determined whether or not the optical sensor SEN4 has detected. If the determination result is "YES", the process proceeds to step S32, and if the determination result is "NO", the process of step S31 is repeated.

In step S32, the stepping motor M3 is stopped, the stepping motor M4 is rotated in the opposite direction to open the arm 9, and the process proceeds to step S33. By this operation, the prize drops from the opened arm 9 to the outlet 11A. In step S33, the optical sensor SEN
It is determined whether or not 3 is detected. Judgment result is "YES"
If it is, the process proceeds to step S34, and the determination result is “N
If it is "O", the process of step S33 is repeated. In step S34, the stepping motor M4 is stopped and the process returns to the start. By this operation, the gripping device 10 and the arm 9 take the initial posture.

Therefore, according to the above-described embodiment, the player can independently insert the left arm 9a and the right arm 9b between his / her intended prize and the prize, so that the gripping device as in the prior art. Compared with the case where it is determined whether or not the prize can be obtained depending on which position above 10 the prize is stopped, the player is convinced even if the prize is not acquired, and the prize is obtained. Can give high satisfaction. Further, since the arm 9 has a structure that moves along the rail 12, it eliminates the disadvantage of the conventional structure that opens and closes, that is, it cannot hold a prize outside the range of rotation, and a wide range is achieved. With, it is possible to grasp the prize, and it is possible to enhance the expectation given to the player. Further, the degree of freedom in the size and shape of the target free gift is increased, and as described above, the outlet 11 can be changed in accordance with the size and the like of the free gift to flexibly cope with it.

When the arm 9 descends to the proper position, the micro switches MS1 and MS2 move to the sensor rod 3
Since it comes into contact with the floor surface 8 by means of 5, the stepping motor M2 can be stopped to start the gripping operation of the prize by the arm 9. However, when the arm 9 descends, the sensor rod 35 collides with the prize. In this case, since the arm 9 has not descended to the proper position between the prizes, the stepping motor M2 is stopped at that point and the next ascending operation is started to prevent damage to the prize. At the same time, it is possible to prevent the device from being overloaded.

Furthermore, when the prize is in contact with the lower end of the arm 9 and the prize is not in contact with the sensor rod 35, or when a large prize comes first on a part of the rail 12 (see, for example, FIGS. 9 and 11). In such a case, one of the corresponding microswitches MS3 to MS6 is turned on and the stepping motor M2 is stopped, so that the prize may be damaged or the device may be overloaded as if the microswitch MS2 to MS6 continues to descend. Can be prevented. That is, in this embodiment, since the rail 12 is provided so that the arm 9 can be moved within a wide range in the width direction, the rail 12 may collide with the prize in some cases. In consideration of this, the microswitches MS3 to MS6 prevent the prize from being damaged and the device from being overloaded.

The present invention is not limited to the above embodiment, and the following structures can be adopted. The same parts as those in the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted. For example, as shown in FIG. 27, instead of providing the elevating device 46, each arm 9 itself may be expanded and contracted to raise the grasped prize.
In this case, the arm 9 is divided into an upper arm 90, a middle arm 91, and a lower arm 92 similarly to the telescopic cylinder 16, and a wire (arm vertical moving means) 94 is wound by a hoisting device (arm vertical moving means) 93. It can be expanded and contracted by rolling it up.

Also in this embodiment, the arms 9 can be inserted between the prizes to obtain the prizes corresponding to the prizes of various shapes and sizes, and further, the arms 9 can be retracted so that the rail 12 can be obtained. Since it is possible to support three points for holding the free gift between and, the holding power of the free gift is enhanced. Therefore,
Since the prize is not dropped when the rail 12 is moved even though the prize is held, there is an effect that the player can play the game with peace of mind.

Further, as shown in FIG. 28, it is also possible to use one telescopic tube 16 and rotate the gripping device 10 around the telescopic tube 16. This way, rail 1
Since the degree of freedom for selecting the direction in which the arm 9 holds the prize can be increased by rotating the arm 2, the arm 9 moving along the rail 12 is inserted between the prizes so as to be gripped from a free angle. You can increase the fun of the game.

Further, in the above embodiment, the arm 9
LED is used to determine how far the arm 9 can be moved to grab the prize after the interval is determined and the arm 9 is lowered.
Although the display is performed by the lamp 15, the LED lamp 15 can be used as an index for determining the range of the initial position of the arm 9 at the beginning of the game. In addition, the floor surface 8 is inclined so as to rise toward the outlet 11,
It is also possible to adopt a mode in which the prize is dropped while shifting. Further, the height of the wall between the floor surface 8 and the outlet 11 may be adjustable. Further, in the above embodiment, the motor is the stepping motor, but a DC motor, an AC motor or the like may be used. Also,
Although the elevating device 46 is moved in the depth direction by the rotating operation of the timing belt 50, the elevating device 46 may be moved by the rotation of a screw shaft having a long lead, for example.
