Further, the shell body 71 of the control body 7 includes a tracking scope 8 corresponding to the target image plane 4, a sensory lever 10 having a trigger member 9 that can be interlocked with the switch 5, and a vibration generator 1.
1 respectively, and the experience lever 10 at the time of firing and at the time of hit.
The vibration is changing.

The tracking scope 8 is located at the front of the game machine main body,
It consists of a semi-transparent plate with an aiming mark M2 engraved in the center, and is configured to be able to swing freely together with the control body 7. The aiming mark M2 of the scope 8 comes to overlap with the target image M on the target image plane 4 when the front trigger member 9 on the rear surface of the control body 7 and the sensory switch 5 are aligned on the same straight line. ing.

The trigger member 9 is adapted to press the pressing portion 5a of the switch 5 with the pressing member 9f on the rear side by sequentially linking the pressing operation of the firing button 9a provided on the front side of the sensory lever 10. That is, when the firing button 9a provided on the front surface of the right sensory lever 10 is pressed, (1) the curved member 9b passing through the bar 10 is pushed inwards, (2) the terminal end of the curved member 9b is pushed inwards; The provided pin P3 rotates the rocking piece 9c about the axis J3, and as a result, the pin P4 of the rocking piece 9c moves the plate member 9d to the rear of the game machine, and The shaped member 9d is configured to swing the movable plate 9e about the axis J4, thereby moving the pressing member 9f toward the front (towards the front of the game machine) and pressing the pressing portion 5a. There is.

The sensory lever 10.10 is a gripping member for transmitting the sound and vibration when the missile is launched and the sound and vibration when the missile hits to the user of the game machine, and is similar to the control bar of a fighter jet and is used to control the control body 7. are provided on both sides. That is, the sensory lever 10.10 has gripping portions 10a, 10a protruding to the outside of the exterior body 100, and a long hole Ns provided at the tip thereof.
, N3, the variable amplitude cam 12 of the vibration generating section 11 provided inside the exterior of the main body 100 is fitted, and the variable amplitude cam 12 rotates in accordance with eccentric rotation of the axis J.

It is designed to be able to swing and vibrate around the center.

Here, the vibration generating section 11 includes a rectangular cylinder body 11a having a drive motor (not shown) inside, and is provided along the depth direction of the fixed body 2 at the center of the control body 7. There is.

Here, as shown in Figure 1.2, the variable amplitude cam 12 is composed of a fan-shaped drive piece 13 and a driven rotary body 14, and in response to forward and reverse rotation of the drive piece 13, the sensory lever 12 is moved with different amplitudes.
It is designed to be able to vibrate 0.10.

The fan-shaped drive piece 13 has a drive pin P5 erected at an eccentric position corresponding to the key of the fan, which is interlocked with a motor in the rectangular cylinder 11a of the vibration generating part 1, and can be rotated forward or backward by the motor. It is configured so that it can be reversed (in the figure, the forward direction is the direction a, and the reverse direction is the direction b). On the other hand, the driven rotor 14 has an elongated hole N that determines a different amount of eccentricity at each end.
4 through the drive pin P of the drive piece 13, and a U-shaped receiving member U that can be secured to the front part in the rotating direction of the drive piece 13 even if the drive piece 13 rotates in either forward or reverse direction. We are prepared. Here, the elongated hole N4 and the receiving member U are provided eccentrically with respect to the center of the driven rotary body 14. Therefore, as shown in the second diagram (a), when rotating forward (direction a), the center of the pin P3 of the drive piece 13 and the center of the driven rotating body 14 correspond to one end of the elongated hole N4. When the eccentricity S1 is determined and the rotation is reversed (in the b direction), the center of the pin P3 of the drive piece 13 and the center of the driven rotary body 14 are set so that the eccentricity S2 corresponding to the other end of the elongated hole N4 is (However, Sl < s2). That is, during forward rotation, a small amplitude vibration corresponding to the small eccentricity S1 is generated, and during reverse rotation, a large amplitude vibration corresponding to the large eccentricity S1 is generated, which can be transmitted to the sensory lever 10.1°. ing.

It should be noted that the variable amplitude cam of the present invention is of course applicable not only to sensory game machines but also to any device that requires different vibration characteristics.

Reference numeral 21 denotes a shot-down number counter, and the counter 21 is provided on the front of the game machine main body 100, near the vibration generating section 11, and is configured to be interlocked with the motor in the vibration generating section 11 via the claw piece 20. There is.

The counter 21 can be rotated via the claw piece 2o only when the motor is reversed, and moreover, can be rotated by a certain angle. That is, the game machine of this embodiment is configured to operate each time the hit mode is switched, and to increase the number of hits by one and display it on the front of the main body 100.

In this example, the small vibration during forward rotation simulates the shooting vibration during missile launch, and the large vibration during reverse rotation simulates the shock vibration at the time of a hit, and the system is configured to emit a simulated sound at the same time. Of course, the characteristics of this vibration and sound are changed as appropriate depending on the content of the game.

In the above embodiment, when the pedestal 1 is set on the desk, the tracking scope 8 is located at an angle that is easy to see in front of the player. When the power switch I5 is turned on, a BG sound suitable for a space game is generated, and the target image 4 is irregularly swung vertically and horizontally by the oscillating means 6 in front of the background image T that rotates at a constant speed. . Here, the player grasps the sensory lever 10.10 with both hands, aiming mark M of the tracking scope 8, and target throat mark M2 of the target image 4.
The tracking body 7 is appropriately swung so that they match. and,
When the marks M1 and M2 are about to match, when the firing button 9a of the trigger member 9 is pressed with the thumb of the right hand, the member 9f is directed toward the pressing member 5a of the switch 5 via the members 9b, 9c, 9d, and 9e. is pressed.

At this time, if the center lines of the member 9f and the member 5a do not match, a missile launch sound will be generated, the motor of the vibration generator 11 will rotate in the normal direction, and the fan-shaped rotating member 13 will pass through the receiving member U into the elongated hole N4. Drive pin P is shifted to one end to rotate driven rotary body 14, and small amplitude vibration of eccentricity S1 is transmitted to sensory lever 10.10.

On the other hand, when the center lines of the member 9f and the member 5a are successfully aligned, the member 51 moves toward the front and switches on to the hit mode, and the reflecting mirror 5b changes to the light emitting lamp L.
, the background image T and the target image 4 suddenly become brighter and at the same time an explosion sound is generated. Then, the motor in the vibration generating part 11 rotates in reverse, and the fan-shaped rotating member 13 shifts the drive pin P4 to the other end of the elongated hole N through the receiving member U, and moves the driven rotating body 14 by an eccentric amount S2. Rotate the long hole N
, transmits a large amplitude to the sensory lever 10.10.

Further, each time the reverse rotation is started, the shot down marker 20 rotates the counter 21 by a predetermined angle to increase the shot down number by one.
