FIG. 4 is a block diagram of a light gun according to the prior art. According to this design, the light gun A comprises a control circuit A1, a photo receiver A2, a firing button A3, a communication interface A4, an autoloading switch A5, an autofiring switch A6, a semiauto firing switch A7, and an autofiring plus autoloading switch A8. The communication interface A4 allows communication between the light gun A and a game machine main unit B. When the player pressed the firing button A3, the photo receiver A2 receives a signal from a display screen C indicative of the coordinates data of the impact point of the shot (bullet), and the control circuit A1 immediately feeds back the impact point signal to the game machine main unit B, for enabling the game machine main unit B to calculate the coordinates of the impact point at the display screen C and to further proceed with further game program processing. When playing the game, the user can use the autoloading switch A5, the autofiring switch A6, the semiauto firing switch A7, and the autofiring plus autoloading switch A8 to control the operation of the simulated gun in the game.
  • However, the aforesaid autoloading switch A5, autofiring switch A6, semiauto firing switch A7 and autofiring plus autoloading switch A8 are respectively provided for on/off two positions selections. For example, when switched on the autoloading switch A5, the light gun A will automatically reload the bullets before empty; when switched off the autoloading switch A5, bullet reloading operation will be executed after the player achieves a particular operation control. However, different magazines for different guns carry different amount of bullets. For example, some magazines allow loading of 6 bullets, and some others allow loading of 15 bullets. The on/off autoloading switch A5 is not highly compatible to different shooting game programs.
  • 8Further, if the autofiring switch A6 is “on” position, the light gun A will keep firing the bullets when pressed the firing button A3. On the contrary, if the autofiring switch A6 is “off” position, the light gun A will fire only one bullet each time the player pressed the firing button A3. However, the firing speed varies with different game programs. In one game program, the simulated gun may be set to fire 3 bullets in one second. In another game program, the simulated gun may be set to fire 10 or more bullets in one second. However, the autofiring switch A6 allows the light gun A to fire bullets at a constant speed. This is a compatibility problem.
  • Further, the sound effect to match the light gun A in a conventional shooting game comes from the audio output at the display screen C but not from the light gun A itself. When playing the game, the background music of the game disturbs the firing sound of the light gun A, causing the player unable to fully enjoy the virtual reality of the game.
