Abstract

A light gun, which includes a control circuit, which communicates with a game machine main unit through a communication interface provides the game machine main unit with the coordinates data of the aiming point at a display screen detected by a position sensor, a firing button, which outputs a firing signal to the game machine main unit through the control circuit, and an autoloading control for setting the number of bullets to be reloaded automatically for enabling the light gun to reload bullets automatically subject to the set number after firing of a predetermined number of bullets.

Claims

1. A light gun used with a game machine main unit and a display screen

to play a shooting game, the light gun comprising:

a control circuit;

a communication interface, which allows communication between said control circuit and said game machine main unit;

a position sensor, which detects the aiming point of said light gun at said display screen and sends the coordinates data of the aiming point to said game machine main unit through said control circuit;

a firing button adapted to output a firing signal to said game machine main unit through said control circuit;

wherein said control circuit has an autoloading control electrically connected thereto for setting the number of bullets to be automatically reloaded for enabling said light gun to reload bullets automatically subject to the set number after firing of a predetermined number of bullets.

2. The light gun as claimed in claim 1, wherein said autoloading control allows to set the number of bullets to be 0˜

1+N, and the autoloading function is off when adjusted to 0.

3. The light gun as claimed in claim 1, wherein said control circuit further has a switch set electrically connected thereto for function control.

4. The light gun as claimed in claim 3, wherein said switch set includes an autofiring switch, which allows the light gun to fire bullets automatically when switched on.

5. The light gun as claimed in claim 3, wherein said switch set includes a semiauto firing switch for initiating a semiauto firing function.

6. The light gun as claimed in claim 3, wherein said switch set includes an autofiring plus autoloading switch for initiating an autofiring plus autoloading function.

7. A light gun used with a game machine main unit and a display screen to play a shooting game, the light gun comprising:

a control circuit;

a communication interface, which allows communication between said control circuit and said game machine main unit;

a position sensor, which detects the aiming point of said light gun at said display screen and sends the coordinates data of the aiming point to said game machine main unit through said control circuit;

a firing button adapted to output a firing signal to said game machine main unit through said control circuit;

wherein said control circuit has an autofiring speed control electrically connected thereto and adapted to let the player adjust the firing speed.

8. The light gun as claimed in claim 7, wherein said autofiring speed control is settable to autofiring zero speed mode, semiauto firing mode, and 1˜

1+N mode selectively, and the autofiring function of the light gun is off when adjusted said autofiring speed control to said autofiring zero speed mode.

9. The light gun as claimed in claim 7, wherein said control circuit further has a switch set electrically connected thereto for function control.

10. The light gun as claimed in claim 9, wherein said switch set includes an autoloading switch, which allows the light gun to reload bullets automatically.

11. The light gun as claimed in claim 9, wherein said switch set includes an autofiring plus autoloading switch for initiating an autofiring plus autoloading function.

12. A light gun used with a game machine main unit and a display screen to play a shooting game, the light gun comprising:

a control circuit;

a communication interface, which allows communication between said control circuit and said game machine main unit;

a position sensor, which detects the aiming point of said light gun at said display screen and sends the coordinates data of the aiming point to said game machine main unit through said control circuit;

a firing button adapted to output a firing signal to said game machine main unit through said control circuit;

wherein said control circuit has an autoloading control electrically connected thereto for setting the number of bullets to be automatically reloaded for enabling said light gun to reload bullets automatically subject to the set number after firing of a predetermined number of bullets, and a speaker electrically connected thereto for producing a sound corresponding to the operation of the light gun when firing/reloading a bullet.

13. A light gun used with a game machine main unit and a display screen to play a shooting game, the light gun comprising:

a control circuit;

a communication interface, which allows communication between said control circuit and said game machine main unit;

a position sensor, which detects the aiming point of said light gun at said display screen and sends the coordinates data of the aiming point to said game machine main unit through said control circuit;

a firing button adapted to output a firing signal to said game machine main unit through said control circuit;

wherein said control circuit has an autofiring speed control electrically connected thereto and adapted to let the player adjust the firing speed, and a speaker electrically connected thereto for producing a sound corresponding to the operation of the light gun when firing/reloading a bullet.
