Description

[Detailed description of the invention] [Field of industrial application] The present invention is a type of game machine in which a player uses a striking tool to hit targets that randomly appear from among a plurality of holes provided on the surface of a game board. This invention relates to an improvement of a target elevating device for a sortie game device.

[Conventional technology]

This type of hitting game device is known as ``whack-a-mole,'' which uses a target imitating a mole character, and is widely used in amusement parks and the like.

A target elevating device for such a hitting game device was previously disclosed in Japanese Utility Model Publication No. 56-3028, using a lever tilted by a crank mechanism by the rotation of a motor, and using the lever to move a main shaft with a target provided at the upper end. A device is disclosed in which the target is raised and lowered by pushing up.

However, in the above-mentioned target elevating device, the main axis of the target is tilted by a crank mechanism using a lever provided on the motor, so if the target is hit, overload will be applied to the mechanical parts and the motor, and there is a risk of damage to the bearings and levers. Furthermore, since the motor is controlled to rotate in forward and reverse directions, the control becomes complicated and there are problems in that the device often breaks down.

[Problem that the invention attempts to solve]

The present invention has been developed based on the above-mentioned viewpoints, and the object of the present invention is to provide a target elevating device with a simple and inexpensive structure, and to provide a device that can be used to hit a target with a striking tool. Therefore, it is an object of the present invention to provide a hitting game device in which mechanical parts are not damaged.

[Means for solving problems]

The above-mentioned object is to provide the above-mentioned percussion game machine with a main shaft that supports a target at the upper end, a device that supports the main shaft so that it can be raised and lowered between an upward movement end point and a downward movement end point and approximately vertically; an arm pivotably supported on the main shaft and capable of tilting between a substantially horizontal first position and a second position in which the tip is located above the first position; a spring that applies torque to the arm so as to cause it to rotate; a cam having a protrusion that releases the arm and allows the main shaft to freely fall to the end point of its downward movement; a motor that rotates the cam; a switch that is operated by the cam and controls the rotation of the motor; a switch that operates at the end of the movement and controls the rotation of the motor; a timer that operates by the command switch that operates at the end of the upward movement of the main shaft; and a timer that operates in response to the operation of the motor operation command switch and timer. This is achieved by providing the hitting game device described above, which is characterized in that it is equipped with a target elevating device comprising a device for controlling the elements.

[Effect]

The target elevating device of the hitting game device of the present invention is constructed as described above, whereby the cam rotates due to the rotation of the motor, and the arm that engages with the cam is held by the biasing force of the spring and rises. When the target reaches the end of its upward movement and the timer has stopped the target, if the player uses a striking tool to hit the target strongly, the target's arm, which is tiltable on its main axis, will be struck by the biasing force of the spring. It resists and tilts, coming off the cam and falling downward. This will display the score.

In the above configuration, since the motor only performs rotational motion, the device is not damaged and can be easily and inexpensively constructed.

The target elevating device 11 according to the present invention is provided in the casing 2 so that the targets 9, 9 can appear and retract freely in correspondence with the plurality of holes 8, 8 in the inclined board surface 3 of the play table.

At the center of the lower end of the target 9, a square tubular main shaft 13 is supported vertically by bearings 14, 14' so as to be vertically movable.
is attached and is supported on the top of the support base 12 by this support device.

The arm 15 is tiltably attached to a pivot shaft 16 on the main shaft 13.
Rotating torque is applied to the roller 17 side of the arm 15 by the tension spring force of a spring 21 attached to the opposite side of the roller 17 with respect to the pivot shaft 16. The roller 17 at the tip thereof is in contact with a buffer member 20 attached to the receiving plate 19 so as to be in a substantially horizontal first position.

The cam 24 has cam pieces 24a, 24a of the same shape formed radially in all directions, and the motor 2
When the cam 24 rotates counterclockwise in FIG. 2 due to the rotation of 3, the cam piece 24a engages the roller 17 and raises the main shaft 13 via the arm 15 from the downward movement end point to the upward movement end point shown in the figure. It is something.

Here, the torque force applied to the tip roller 17 portion of the arm 15 by the tension spring force of the spring 21 is larger than the weight of the target 9, the main shaft 13, etc., and the frictional resistance between the main shaft 14 and the bearings 14, 14'. When the target 9 is hit by the striking tool 10 while moving to the end point of the upward movement, the arm 1

As shown in the figure, in the target elevating device 11 according to the present invention, the main shaft 13 reaches the end point of upward movement due to the rotation of the motor 23, and the micro switch 25 is activated.
When it turns ON, the motor 23 stops, the timer starts at the same time, and the output continues for the predetermined time shown in the figure.
It becomes ON. After that, when the set time of the timer passes and the timer turns OFF, the motor 23 rotates again and the micro switch 25 turns OFF.
When the roller 17 comes off the cam piece 24a, the main shaft 13
falls to the end point of its downward movement.

Furthermore, when the player hits the target 9 while the output of the timer is ON, the arm 15 tilts and the main shaft 13 falls to the end point of the downward movement as described above, turning the micro switch 25 OFF. The score will be displayed on the display board 4.

Thus, in the hitting game device 1, when the player inserts a coin from the fee slot 5 and presses the operation command button 7, the plurality of targets 9, 9 are randomly moved by the target elevating device 11, 11 as described above. It appears from the holes 8, 8, and if the player hits the top of the appearing target 9 using the hitting tool 10 during the play time, the target 9 will fall, and the number of hits will be accurately counted. This is what is displayed on the display board 4.

Note that the configuration of the present invention is not limited to the above-described embodiment; for example, a tension spring 21 is used to tilt the arm 15, but a compression spring may be used to bias the arm from below.
