Hereinafter, an embodiment according to the present invention will be described with reference to FIGS.
FIG. 1 is an external view of a shooting game apparatus 1 according to the present embodiment.
A display 3 is attached to the support column 4 behind the gantry 2 in which the game main body is built.

On the floor surface in front of the gantry 2, a foot operation input device 10 as an operation input means is connected to the gantry 2.
A simulated gun 30 simulating a handgun is placed on the gantry 2, and speakers 6 are arranged on the upper left and right of the gantry 2.

  In the shooting game apparatus 1, the player P places one foot on the foot operation input device 10, stands in front of the gantry 2, holds the simulated gun 30, operates the foot operation input device 10 with his feet, and displays 3 The target object displayed on the screen is aimed and shot with the simulated gun 30 to enjoy the play.

  Referring to FIGS. 1 to 3, foot operation input device 10 is a flat rectangular housing, and support brackets 11L and 11R project from the left and right ends on the upper surface, and hinges are respectively attached to support brackets 11L and 11R. A left pedal 13L and a right pedal 13R are provided so as to be swingable up and down via 12L and 12R.

As shown in the plan view of FIG. 2, the foot operation input device 10 has a left-right pedal 13L and a right-hand pedal 13R that have a left-right width substantially equal to the width of the foot and a narrower width in the back direction. A footrest plate 14 is formed.
The footrest plate 14 is positioned lower than the left and right support brackets 11L and 11R, and the left pedal 13L and the right pedal 13R are inclined from the left and right support brackets 11L and 11R toward the footrest plate 14, respectively.

Referring to FIG. 3 which is a cross-sectional view of the left pedal 13L, a compression spring 16 is interposed between the bottom plate 15 and the left pedal 13L to urge the left pedal 13L upward. The engagement piece 17a erected on the bottom plate 15 and the engagement piece 17b suspended from the lower surface of the left pedal 13L engage with each other, and the upward swing of the left pedal 13L biased upward is raised to a predetermined height. It is regulated by.
In a state where the left pedal 13L is regulated by the engagement pieces 17a and 17b, the upper surface of the left pedal 13L and the upper surface of the footrest plate 14 form a continuous surface without a step.

  Further, a projector 18a such as an LED and a light receiver 18b are arranged to face each other at a predetermined position on the bottom plate 15, and a blocking piece 18c protruding from the lower surface of the left pedal 13L can be inserted between the light projector 18a and the light receiver 18b. The left pedal switch 18L is configured.

  Therefore, when the left pedal 13L is stepped and swings downward against the compression spring 16, the blocking piece 18c is inserted between the projector 18a and the light receiver 18b to block the light from the projector 18a and block the light to the light receiver 18b. Therefore, the left pedal switch 18L can detect the depression of the left pedal 13L.

On the other hand, the right pedal 13R has the same structure as the left pedal 13L, and is also provided with a right pedal switch 18R, so that the depression of the right pedal 13R can be detected.
As a pedal switch, the depression amount may be detected as an analog value with a volume or an encoder.

The foot operation input device 10 as described above is operated by one foot of the player P, and the foot Pf (right foot in FIG. 2) is placed on the footrest plate 14 as shown by a two-dot chain line in FIG. The left pedal 13L can be depressed by swinging the toe to the left about the heel, and the right pedal 13R can be depressed by swinging the toe to the right.
In this way, the player P can selectively operate the left pedal 13L or the right pedal 13R with a simple operation with one foot.

  The footrest plate 14 becomes narrower as the left / right width goes deeper, and the left pedal 13L and the right pedal 13R are gradually approaching. If the toes are swung left and right, the left pedal 13L and the right pedal 13R can be selectively depressed easily.

Next, the simulated gun 30 will be described with reference to FIGS.
The simulated gun 30 simulates a handgun, and a gun handle 32 extends downward from the rear part of the barrel 31, and a trigger 34 is provided at the base of the gun handle 32 so as to be slidable back and forth.
The barrel 31 and the gun handle 32 are integrally formed of a left and right half gun casing 30a.

A lens 40 is fitted into the tip of the barrel 31, a photo sensor 41 is disposed behind the lens 40, and a signal processing board 42 is disposed behind the photo sensor 41.
The photo sensor 41 detects the light passing through the lens 40, and the signal processing board 42 processes the signal.

The trigger 34 is slidably supported back and forth together with the sliding portion 35 and is urged forward by a spring 36.
A trigger switch 37, which is a limit switch located above the sliding portion 35, is arranged so that its operating contact 37a is operated by the projection 35a of the sliding portion 35.

That is, when the trigger 34 is pulled, the sliding portion 35 slides backward against the spring 36 together with the trigger 34, and the projection 35a of the sliding portion 35 operates the operating contact 37a to turn on the trigger switch 37. .
The signal lines extending from the signal processing board 42 and the signal lines extending from the trigger switch 37 are bundled in a bundle and extend from the bottom of the gun handle 32 to the outside as a cable 38.

An impact vibration generator 50 is incorporated in the rear part of the barrel 31.
A one-way drive type electromagnetic solenoid 51 is fixed to the gun casing 30a with the plunger 52 oriented in the front-rear direction, and a slide plate member 55 is slidably supported back and forth along the upper surface of the electromagnetic solenoid 51. ing.

The slide plate member 55 has a horizontal central portion 55c formed in a rectangular shape (see FIG. 5), a narrow forward extending portion 55f extending forward from the horizontal central portion 55c, and a front end of the front extending portion 55f. The left right side portion is bent downward to form a pair of left and right bent front end portions 55ff.
On the other hand, a narrow rear extension 55r extends rearward from the horizontal central portion 55c, and a front end of the rear extension 55r is bent downward to form a bent rear end 55rr.
The slide plate member 55 is a metal plate and has elasticity.

  The slide plate member 55 has four elongated holes 55ch formed in the front and rear at four corners of a rectangular horizontal central portion 55c, and four screws screwed to the upper wall of the case 51a covering the electromagnetic solenoid 51. 56 is erected through the four long holes 55ch, and restricts the sliding of the slide plate member 55 forward and backward within a certain range.

The pair of left and right bent front end portions 55ff of the slide plate member 55 sandwich the front end portion of the plunger 52 of the electromagnetic solenoid 51 from the left and right, and are connected to the front end portion by a pin 57.
A compression spring 53 is interposed between the front end portion of the plunger 52 and the front wall of the case 51 a of the electromagnetic solenoid 51.

  Therefore, when the electromagnetic solenoid 51 is not energized and is in a demagnetized state, the plunger 52 and the slide plate member 55 are in the forward position by the compression spring 53 (the state shown in FIGS. 4 to 6), and the electromagnetic solenoid 51 is energized. When excited, the plunger 52 moves instantaneously backward along with the slide plate member 55 against the compression spring 53.

Since the electromagnetic solenoid 51 is energized instantaneously, the plunger 52 and the slide plate member 55 are immediately returned to the front by the compression spring 53.
In addition, an impact rubber member 54 is fixed at a predetermined position in front of the plunger 52, and the plunger 52 returning to the front by the compression spring 53 is received.

On the other hand, on the rear side of the slide plate member 55 facing the bent rear end portion 55rr, an impact rubber member 61 is fitted and attached to the support bracket 30b, and is a circle that is perforated in the front-rear direction of the impact rubber member 61 A weight member 62 having a columnar shape passes through the hole and is supported so as to be slidable in the front-rear direction.
The weight member 62 is formed with a flange 62a at a substantially central portion, and the flange 62a is located behind the impact rubber member 61.

  A circular opening 30d having an inner diameter substantially equal to the outer diameter of the weight member 62 is formed in a portion of the gun casing 30a facing the weight member 62 of the rear end wall 30c of the barrel 31. A compression spring 63 is interposed between the opening end surface of the weight member 62 and the flange 62 a of the weight member 62.

When the trigger 34 is not pulled, the projection 35a of the sliding portion 35 is positioned in front of the operating contact 37a of the trigger switch 37 as shown in FIG. The plunger 52 is urged by a compression spring 53 and abuts against an impact rubber member 54 and is in a forward position together with the slide plate member 55.
The weight member 62 is in a forward position with the flange 62a abutting against the impact rubber member 61 by the compression spring 63, and moves forward and backward so as not to generate abnormal noise.

Here, when the trigger 34 is pulled, referring to FIG. 7, the projection 35 a of the sliding portion 35 operates the operation contact 37 a of the trigger switch 37 to turn on the trigger switch 37.
Then, the electromagnetic solenoid 51 is excited and the plunger 52 moves rearward against the compression spring 53 together with the slide plate member 55, and the bent rear end portion 55rr of the slide plate member 55 first comes into contact with the weight member 62. .
FIG. 7 shows this moment.

Since the bent rear end portion 55rr of the elastic slide plate member 55 abuts against the weight member 62, the bent rear end portion 55rr is in contact with the weight member 62 without repelling the weight member 62, and further rearward As shown in FIG. 8, the weight member 62 pushed by the bent rear end portion 55rr of the slide plate member 55 collides with the opening end surface of the circular opening 30d via the compressed compression spring 63.
At substantially the same time, the bent rear end portion 55rr of the slide plate member 55 collides with the impact rubber member 61 that supports the weight member 62.

  The weight member 62 is pushed by the plunger 52, which is a heavy object, through the elastic slide plate member 55 and collides with the opening end surface of the circular opening 30d, which is a restricting member. It gives the gun body a realistic shock vibration with a heavy feeling similar to, and can generate a realistic impact sound, allowing the player to experience a realistic shooting sensation.

In addition, shock vibration in which the elastic slide plate member 55 collides with the impact-receiving rubber member 61 is applied substantially simultaneously, so that more realistic shock vibration can be applied to the gun body.
The impact sound accompanying the impact vibration is not confined inside, and can pass through the rear circular opening 30d to the outside to generate a realistic shooting sound.

  Since the electromagnetic solenoid 51 is energized instantaneously and demagnetized immediately, the plunger 52 and the slide plate member 55 return to the front by the compression spring 53, and the plunger 52 collides with the impact rubber member 54, and this shock vibration is also generated. Join later.

  The player P holds the simulated gun 30 as described above and shoots at the target object displayed on the screen of the display 3. The direction of the muzzle of the simulated gun 30 is detected. In addition, the photosensor 41 provided at the tip of the barrel 31 of the simulated gun 30 is used.

A plurality of infrared emitters 5 for emitting infrared rays are arranged around the display 3, the infrared rays emitted from the infrared emitters 5 are detected by the photosensor 41 of the simulation gun 30, and the detection signal is processed by the signal processing board 42. The muzzle direction can be calculated from the processing signal.
In a cathode ray tube display, the muzzle direction can also be obtained by detecting scanning light.

A schematic block diagram of a control system in the shooting game apparatus 1 is shown in FIG.
A control system is configured on the game control board 80 built in the gantry 2.
The game control board 80 generates a sound effect and the like, a game arithmetic processing unit 81 that roughly controls the entire game, an image composition unit 82 that controls display of the game screen based on the processing result of the game arithmetic processing unit 81, and the like. The voice synthesizer 83 is configured.
The image synthesizer 82 displays an image on the display 3, and the voice synthesizer 83 drives the speaker 6 to generate sound.

The game calculation processing unit 81 includes a game progress means 90, a pedal depression state determination means 91, a muzzle direction calculation means 92, a virtual space state setting means 93, a display screen setting means 94, and the like.
The game progress means 90 controls the progress of the game based on object information, background image information, etc. according to the game program written in the memory. Muzzle direction information is input from stepping mode information and muzzle direction calculation means 92.

The pedal depression mode determining means 91 receives the signals of the left pedal switch 18L and the right pedal switch 18R and determines the mode of depression of the left pedal 13L and the right pedal 13R, that is, which pedal has been depressed. .
That is, it is determined which pedal has been pressed once, whether it has been pressed twice within a predetermined short time (corresponding to a double click in the case of a click operation), or whether it has been continuously pressed for a predetermined time or more. Is output to the game progress means 90.

The muzzle direction calculating means 92 calculates a muzzle direction by inputting a signal processed by the signal processing board 42 from the signal detected by the photosensor 41 of the simulated gun 30 as described above, and the muzzle of the simulated gun 30 is directed. Information on the current direction is output to the game progress means 90.
The muzzle direction information of the simulated gun 30 includes information on where the aim is on the screen of the display 3 and information on whether the muzzle is pointed at the screen of the display 3.

The game progress means 90 moves the various objects arranged in the virtual space assumed in advance to advance the game.
FIG. 10 shows a virtual space assumed by the shooting game apparatus 1.

  In this virtual space 100, drum-shaped defense members 101 are arranged at a plurality of intervals on the front side and the back side, respectively, and the player object (player P moves so as to be hidden by the defense members 101 on the front side). There is an object 102 that corresponds to a hero character that can perform an object), and there is a target object 103 (an object that corresponds to an enemy character that moves according to a program) 103 so as to be hidden by the defense member 101 on the back side.

  The game progress means 90 includes a player object position / motion determination means 90a and various object determination means 90b.

The player object position / motion determining means 90a determines the position and action of the player object 102 based on the determination result of the pedal depression mode determining means 91.
That is, the player object 102 moves to the left or right based on how the player P depresses the left pedal 13L and the right pedal 13R and operates differently during the movement.
The various object determining means 90b determines the position and action of the target object 103 according to the program.

Further, the game progress means 90 includes hit determination means 90c for determining whether or not the shooting with the simulated gun 30 has hit the target object 103.
The hit determination means 90c fires based on the position information of the target object 103 determined by the various object determination means 90b, the muzzle direction information calculated by the muzzle direction calculation means 92, and the ON signal of the trigger switch 37 of the simulated gun 30. It is determined whether or not the target object 103 has been hit.

  The game progress means 90 is provided with an object state changing means 90d, and the object state changing means 90d is determined information / determination information of the player object position / motion determining means 90a, various object determining means 90b, and hit determining means 90c. Accordingly, the states of the player object 102 and the target object 103 are changed.

The virtual space state setting means 93 sets the change of the state of the player object 102 and the target object 103 by the object state changing means 90d in the virtual space 100.
The display screen setting means 94 sets a display screen to be actually displayed on the screen of the display 3 from the state of the virtual space 100 set in this way in accordance with an instruction from the game progress means 90.

  The image composition unit 82 includes an image processing unit 82a and an image forming unit 82a. The image composition unit 82 inputs information about the display screen set by the display screen setting unit 94 and processes it to form an image that the player P actually sees. To display.

A control example in the above control system will be described below.
First, the movement control of the player object 102 by the operation of the left pedal 13L and the right pedal 13R of the player P will be described with reference to the flowchart of FIG.
This control is based on the determination of the pedal depression mode performed by the pedal depression mode determination means 91.

The player P holds the simulated gun 30 and puts either the left or right foot Pf on the footrest plate 14 of the foot operation input device 10 and stands on the screen of the display 3.
Then, the player P swings the toe left and right with the foot Pf placed on the footrest plate 14 as the axis and selectively depresses the left pedal 13L or the right pedal 13R at any time while simulating the target screen with the simulated gun 30. The object 103 is aimed and shot.

  In step 1, it is determined whether or not the left pedal switch 18L is turned on. If it is turned on, the process proceeds to step 2. If not, the process jumps to step 11 to determine whether or not the right pedal switch 18R is turned on. If it is on, the process proceeds to step 12. If it is not on, the process returns to step 1.

Here, when the left pedal switch 18L is turned on, the left pedal 13L is stepped on, and when the light blocking element 18c is inserted between the light projector 18a and the light receiver 18b, the light from the light projector 18a is blocked and does not reach the light receiver 18b. Is on.
The same applies when the right pedal switch 18R is turned on.

When the left pedal switch 18L is turned on in step 1 and the process proceeds to step 2, it is determined whether or not the left pedal switch 18L is turned on again (corresponding to a double click) within a predetermined time.
That is, it is determined whether or not the left pedal 13L is stepped twice in a short time. When the left pedal 13L is stepped twice, the routine proceeds to step 4 where the player object 102 is moved to the specified point on the left side by a special action.

The specified point is a place where the defense member 101 that can hide the player object 102 in the virtual space 100 is present.
FIG. 12 shows an image displayed on the screen D of the display 3 in Step 4.
The player object 102 moves to the defense member 101 on the left side while rolling (special motion).
At this time, shooting with the simulated gun 30 is not possible.

In Step 2, it is determined that the left pedal 13L has not been depressed twice in a short time, and when proceeding to Step 3, it is determined whether or not the left pedal switch 18L is continuously turned on. If 18L is not turned on, it is determined that the left pedal 13L has been depressed only once, and the process proceeds to step 5 to move the player object 102 to a specified point on the left.
In this case, the simulated gun 30 can be aimed at the target object 103 and directed at the screen of the display 3.

FIG. 13 shows an image displayed on the screen D of the display 3 in step 5.
The player object 102 moves to the defense member 101 on the left side while shooting.
On the screen D, an aiming mark 105 in the muzzle direction of the simulated gun 30 is displayed.

When the muzzle of the simulated gun 30 is directed to the screen D of the display 3 and when it is not directed, the screen display is different. When the muzzle of the simulated gun 30 is directed to the screen D, as shown in FIG. The screen is displayed with the main part up, centering on 102, and the target object 103 is also easy to see and easy to aim with the simulated gun 30.
On the other hand, when the muzzle of the simulated gun 30 is not directed to the screen D, the screen displays a wide range of the virtual space 100 as shown in FIG.

  Further, when the player object 102 is not moved and is at the position of the defense member 101 which is the specified point, when the muzzle of the simulated gun 30 is not directed to the screen D, the player object 102 is displayed as shown in FIG. It is a screen that displays the wide range of the virtual space 100 because it is hidden behind the defense member 101 and the target object 103 can be easily found.

  When the muzzle of the simulated gun 30 is directed to the screen D, as shown in FIG. 15, the player object 102 has a screen display in which the main part is easily raised from the defense member 101 to easily aim at the target object 103.

  In this way, the display image is changed depending on whether the muzzle direction of the simulated gun 30 is directed to the screen of the display 3, so that a more effective image can be displayed as the game progresses and an exciting play can be enjoyed. be able to.

If it is determined in step 3 of the flowchart of FIG. 11 that the left pedal switch 18L is continuously on, the process proceeds to step 6 where the player object 102 is moved from the left-side specified point to the left-side specified point. Move.
Shooting is possible during this time.
