[Prior Art] For example, a game-experience game machine is one that enjoys maneuvering techniques, shooting sensations, etc. by performing predetermined operations while responding to a screen that changes in the manner of a high-speed drive or space war. It is widely used as a game console that even adults can enjoy.

With this kind of experience game machine, when maneuvering and shooting,
Mechanical vibration transmitted through a steering lever, a steering wheel, a steering wheel (hereinafter referred to as a bodily sensation member) is an important factor in obtaining a realistic sensation according to a screen. Therefore, in a so-called game center or the like, a large screen is incorporated in a cockpit of a substantially full scale, and it is put into practical use in which a large-sized motor or a hydraulic device gives a sensible vibration. In the field of everyday toys, on the other hand, the number of hands-on game machines that allow users to enjoy realistic games on their desks is expanding. In this case, particularly in a space war game in which battle scenes are included, the characteristics of the sensory vibration that conveys a feeling of weight and a sense of speed may determine the interest as a game machine.

Therefore, various means for changing the mechanical vibration have been proposed. For example, improvements have been considered in which a plurality of motors are interlocked with the sensation member and the vibration characteristics of the sensation member are appropriately changed when the operation mode is changed to generate more realistic sensation vibration.

[Problems to be Solved by the Invention]

However, in the above-described conventional sensation game machine, a mechanism including a motor and a vibration generating member linked to the motor is separately required for each type of sensation vibration mode, which makes the device large, complicated, and expensive. There was a risk of being invited.

The present invention has been made in view of the above points, and an object thereof is to provide a vibration generating means capable of generating vibrations of different suppressions with a simple mechanism.

The amplitude variable cam is configured by providing a receiving member that biases the pin so that the pin is positioned. For example, by applying the cam to the vibration generating unit of the sensation game machine, a simple structure including two members is provided. Despite the configuration, it is possible to generate bodily vibrations having different amplitudes.

In this embodiment, the small vibration at the time of forward rotation simulates the shooting vibration at the time of launching a missile, and the large vibration at the time of reverse rotation simulates the shock vibration at the time of hitting, and is configured to emit a simulated sound at the same time. Of course, the characteristics of the vibration and the sound are appropriately changed according to the content of the game.

In the above embodiment, when the pedestal 1 is set on the desk, the tracking scope 8 is positioned at an easy-to-see angle in front of the player. When the power switch 15 is turned on, a BG sound suitable for a space game is generated, and the target image 4 oscillates vertically and horizontally by the oscillating means 6 in front of the background image T rotating at a constant speed. Here, the player grasps the sensation levers 10 and 10 with both hands and sets the sighting mark on the tracking scope 8.

The tracking body 7 is appropriately swung. And mark M ₁ and mark
When M ₂ is about to match, pressing the firing button 9a of the trigger member 9 with the right thumb pushes the member 9f toward the pressing member 5a of the switch 5 via the members 9b, 9c, 9d and 9e. It

At this time, if the center line of the member 9f and the member 5a is in disagreement, with missile launch sound occurs, the motor is rotated forward of the vibration generator 11, the fan-shaped rotating member 13 receives the elongated hole N ₄ through the member U
The driven pin P ₄ is biased to one end of the one to rotate the driven rotor 14, and the small amplitude vibration of the eccentricity S ₁ is transmitted to the sensation levers 10, 10.

On the other hand, if the center lines of the member 9f and the member 5a coincide with each other,
Since the member 51 moves toward the front and is switched on in the hit mode, and the reflection mirror 5b is close to the light emitting lamp L, the background image T and the target image 4 become sharply bright and at the same time an explosion sound is produced. Then, the motor in the vibration generating section 11 reversely rotates, and the fan-shaped rotating member 13 shifts the drive pin P ₄ to the other end of the slot N ₄ via the receiving member U to rotate the driven pin with the eccentricity S _2. Rotate the body 14 and, through the long hole N ₁ , the sensation lever 1
A large amplitude is transmitted to 0 and 10. Further, each time the reverse rotation is started, the shooting down marker 20 rotates the counter 21 by a predetermined angle to increase the shooting down number by one.
