The boxer 25 is a boxer that the player himself controls, and by operating the lever 5, the arms of the boxer 25 move in the same way, and the horizontal swinging of the swinging support 3 moves the background and boxers. 25
movements can be displayed realistically.

FIG. 4 is a partially cutaway side view of the boxing game device 1, showing the swinging mechanism of the swinging support 3 relative to the base 2. FIG.

The base 2 has a box shape, and a circular hole 31 is bored in the approximate center of the upper plate 30.
A reinforcing plate 33 having a circular hole 32 concentric with 1 and having a larger diameter is stretched.

Then, three rotating rolls 35 are placed on the reinforcing plate 33.
The swinging support body 3 is swingably supported via.

The three rotating rolls 35 are provided on the bottom plate 34 of the swinging support 3 at equal intervals on the same circumference, and the axial direction of each rotating roll 35 is directed toward the center P of the circle forming the circumference. The swing support body 3 is supported so as to be rotatable (swingable) about the center P.

A disc 37 is screwed and fixed to the lower center of the bottom plate 34 of the swing support 3 with a buffer member 36 interposed therebetween by bolts 38 and nuts 39.

The disc 37 is positioned to be fitted into the circular hole 32 of the reinforcing plate 33.

The center of the disk 37 coincides with the center P, and a cylinder 40 is vertically provided below the center, and the cylinder 40 passes through the circular hole 31 of the upper plate 30 of the base 2.

A bearing 41 is interposed between the upper plate 30 and the disc 37 via a buffer member to fix the position of the disc 37, that is, the swing support 3, and to fix the swing support 3 with respect to the base 2. It can swing smoothly around P.

The cylinder 40 rotates together with the swing support 3, and its lower part is rotatably supported by a fixed frame 42, and projects horizontally in a fan shape from a predetermined part of the outer periphery of the cylinder 40, and its end edge A gear 43 having a tooth profile is fixed thereto.

As shown in FIG. 5, a swing angle detection volume 46 fixedly supported by an adjustment screw 45 on a support plate 44 fixed to a fixed frame 42 is arranged near the rear of the cylinder 40, and the swing angle detection volume 46 is fixedly supported by an adjustment screw 45. A gear 47 is fitted onto the operating shaft of the volume 46 and meshes with the gear 43.

The engagement between both gears 47 and 43 is determined by adjusting screw 45.
It can be adjusted by

Therefore, the rotation of the cylinder 40 swings the gear 43 and operates the swing angle detection volume 46 via the gear 47, so that the swing angle of the swing support 3 is determined by the swing angle detection volume 46. can be detected.

Next, the operating mechanism of the lever 5 will be explained based on FIGS. 6 and 7.

A rectangular box 50 is fixed to the swing support 3 at a position below the CRT display 4 on the swing support 3, and the operating mechanism of the lever 5 is housed inside the box 50.

Two support plates 51 having a U-shaped cross section are fixed to the inner surface of the rear side plate 50a of the box 50 on the left and right sides with both arms 51a protruding forward. The support shaft 52 is oriented in the left and right horizontal direction.
A lever support member 53 is provided with its base end pivotally supported by and oriented in the front-rear direction.

The lever support member 53 consists of left and right side plates 53a and a bottom plate 53b that are long in the front and back direction.
The rear end portion of a is pivotally supported by each arm portion 51a via a support shaft 52.

A U-shaped spring receiving member 54 is fixed to the left and right side plates 53a to sandwich the center position of the lever support member 53 from below, and a spring 56 is attached between the spring receiving member 55 fixed to the bottom plate of the case 50. is installed with a slight inclination.

Therefore, the lever support member 53 has its base end pivotally supported by each arm 51a, and its center part supported by the spring 5.
6, so that the tip of the lever support member 53 can swing up and down against the spring 56.

The lever 5 is inserted into the lever support member 53 so as to be oriented in the front-rear direction, and passes through the two front and rear support members 57 and 58 fixed inside the lever support member 53, and swings back and forth. Supported for free movement.

A stopper 59 is fixed to the rear end of the lever 5, and a buffer member 60 is fixed to the rear surface of the stopper 59.

A stopper 61 is fixed to the lever 5 between the support members 57 and 58.
A spring 63 is interposed between the lever 5 and the support member 57 so as to be penetrated by the lever 5.

A projection 62 projects horizontally from a portion 61a of the stopper 61 extending parallel to the side plate 53a, and passes through a horizontally long cutout 65 provided in a part of the side plate 53a.

A plate-shaped rotating member 64 is fixed to the end of the support shaft 66, and the protrusion 62 is loosely fitted into a hole 64a provided near the tip of the rotating member 64.

A gear 67 is fitted to the support shaft 66, and a gear 68a fitted to the operating shaft of the longitudinal position detection volume 68 meshes with the gear 67.

Therefore, when the lever 5 is slid back and forth, the rotating member 64 is moved by the protrusion 62 that moves together with the lever 5.
rotates, and the rotation of the rotating member 64 is caused by the gears 67, 68.
The operating shaft of the longitudinal position detection volume 68 is rotated via a.

By operating this longitudinal position detection volume 68, the longitudinal position of the lever 5 can be detected.

Further, a shock absorber 70 is provided inside the lever support member 53 near its base end.

That is, in the shock absorbing device 70, a rod member 72 is oriented in the front-rear direction and is supported through a support plate 71 fixed to the left and right side plates 53a of the lever support member 53.
A buffer member 73 is fixed to the front end of the bar member 72, a stopper 74 is fixed to the rear end, and a spring 75 is attached between the support plate 71 and the buffer member 73.
is inserted through the rod member 72.

The buffer member 73 faces the buffer member 60 provided at the rear end of the lever 5.

Since the lever 5 is configured as described above, the lever 5 is normally in the forward position due to the force exerted forward by the spring 63, and when force is applied backward from this position, the lever 5 resists the spring 63 and moves backward. When the lever 5 slides, the buffer member 60 at the rear end of the lever 5 comes into contact with the buffer member 73 of the shock absorber 70 and is damped and stopped.

At this time, the position of the lever 5 is determined by the longitudinal position detection volume 68 via the rotating member 64 and gears 67 and 68a.
can be detected.

In addition, a regulation plate 76 in which two vertical holes are formed on the left and right is located in front of the box 50, and the lever 50
passes through a hole in the regulating plate 76, and allows the lever 5 to swing up and down freely, and also regulates the width of the up and down swing.

At predetermined positions on the inner surfaces of the left and right side plates of the box 50, reflective optical sensors 7 are provided, one each on the upper and lower sides, slightly protruding inward.
7 and 78 are fixed.

An actuation plate 79 protruding downward is provided on one of the left and right side plates 53a of the lever support member 53. Passing near the reflective optical sensors 77 and 78, the actuating plate 7
The rectangular small hole 79a drilled in 9 faces the reflective optical sensor 77 when the lever support member 53 is in the upper position, and faces the reflective optical sensor 78 when the lever support member 53 is in the lower position. It's becoming like that.

Therefore, whether the lever 5, which moves up and down together with the lever support member 53, is in an upper, middle, or lower position can be determined by the operating states of the reflective optical sensors 77 and 78.

That is, when the lever 5 is in the upper position, the emitted light from the reflective optical sensor 77 passes through the small hole 79a and the reflective optical sensor 78 is also in the off state, and when the lever 5 is in the lower position The output light of the reflective optical sensor 77 is reflected by the actuating plate 79 and is in the on state, and the output light of the reflective optical sensor 78 is reflected by the small hole 79a.
When the lever 5 is in an intermediate position neither upward nor downward, the emitted light from both reflective optical sensors 77 and 78 is reflected by the actuating plate 79 and the lever 5 is in an on state.

As mentioned above, the lever operation in this boxing game device 1 includes back and forth strokes, up and down swings,
It can be operated in three directions (left and right swinging), and the forward and backward strokes and up and down swinging can be performed independently of each other with the left and right levers.

The longitudinal position of the lever 5 due to the longitudinal stroke is detected by a longitudinal position detection volume, and the vertical position due to the vertical swing of the lever 5 is detected by reflective optical sensors 77 and 78. That is, the left and right swing of the swing support body 3 is detected by the swing angle detection volume 46.

Since the lever 5 enables the above-mentioned movements, by combining various movements, the player can perform attacks such as straight, hook, jab, and deep cut on the left and right, just like in actual boxing, as well as blocking on the left and right, Defenses such as slipping are also possible.

Since the force of the forward and backward stroke is absorbed by the shock absorber 70 at an appropriate point, the player can feel as if he is hitting the opponent, and can enjoy more realistic play.

The movement of the player can be determined by analyzing the detection values of the swing angle detection volume 46, the longitudinal position detection volume 68, and the reflective optical sensors 77, 78.
Regarding the detected value, it is possible to determine not only the position but also the presence or absence of a punch by calculating the speed of movement.

The control system of this embodiment will be explained below.

FIG. 8 is a block diagram of the control system, in which the swing angle detection volume 46 and the longitudinal position detection volume 6 are
The analog quantity detection signal of 8 is sent to the A/D converter 10.
0 is converted into a digital signal and input to the computer, which turns on/off the reflective optical sensors 77 and 78.
The off signal is input directly to the computer.

The microcomputer that processes the above input information includes a microprocessor MPU101, a ROM102 that stores an operation control program for the microprocessor MPU101, and a microprocessor.
It consists of a RAM 103 used for the work of the MPU 101, and controls the progress of the game.

In addition, there is an operation information memory 104 that stores the states of various flags for analyzing the movement of the lever 5 and other operation information.

The image control system of the CRT display 4 is roughly divided into character image setting means 105 that forms character images of the opponent boxer and the boxer corresponding to the player, and a background image generation means 106 that generates background images of the ring, spectators, etc. , a timing circuit 107 for forming XY addresses corresponding to vertical and horizontal synchronization signals, and the character image setting means 10.
5. It consists of a priority circuit 108 that selectively outputs images from the background image generation means 106 according to the priority, and a color expansion circuit 109 that makes the colors of the image information output from the priority circuit 108 more diverse.

The character image setting means 105 includes an image information parameter memory 110 that stores and holds image information parameters set based on the game program from the operation information, and a ROM, and a character image memory 111 that corresponds to various image information parameter memories. and a control circuit 112 that compares the image information parameters with the XY addresses corresponding to the vertical and horizontal synchronization signals, sets the display position on the screen, and outputs the corresponding image information from the character image memory 111. .

Background image generation means 1 that generates a background image next
06 includes a character generator 113 that outputs a planar image element, and a scroll 114 that expands this image element.

This background image generating means 106 changes as the lever 5 swings from side to side (swings together with the swinging support 3), and is arranged so that the background seen from the perspective of a boxer corresponding to the player is displayed on the screen. .

Operation procedure and lever 5 in the above control system
The processing procedure for the movement will be explained based on the flowcharts shown in FIGS. 9 to 12.

The flowchart in FIG. 9 outlines the overall flow of this device.

First, when the power is turned on, the title of the game is displayed on the CRT display 4 (step
Next, it is determined whether or not a coin has been inserted to start the game (step), and if no coin has been inserted, an initial demonstration is displayed on the screen (step), and in step it is determined whether or not the timer has counted a predetermined time, and if not, the process returns to step , and these steps , , , are repeated to wait for the time to elapse, and when the predetermined time has elapsed, a ranking list is displayed (step), and the process returns to step again.

The above steps are repeated until a coin is inserted, and once the coin is inserted, the process progresses from step to step and waits for the start button to be pressed.

When the start button is pressed, the game starts (step), and game processing is performed until the game ends (step,). When the game ends, a new ranking list is displayed (step), and the end of the game is displayed. (step) and return to step.

The game processing routine in this step is illustrated in FIG.

First, when entering the routine, initial settings (steps) of various parameters for starting the game are performed.
Then, the initial settings (steps) of each parameter for the game are made, and then the movements of the left and right levers are read from the detection values of the swing angle detection volume 46, the longitudinal position detection volume 68, and the reflective optical sensors 77 and 78. (Step〓〓).

That is, the stroke data is read from the detected value of the longitudinal position detection volume 68, and the reflective optical sensor 7
The vertical position data is read from the detected values of 7 and 78, and the horizontal position data is read from the detected value of the swing angle detection volume 46.

Then, compare and calculate each of the above data, and
Judging the movement and match situation (step 〓〓),
Based on the same judgment, the image is displayed (step 〓〓).

Based on the judgment of the match situation at Step 〓〓, it is determined in Step 〓〓 whether the opponent has been knocked out, and if the opponent has been knocked out, the process returns to Step 〓〓.

At this time, the CRT display 4 shows a screen showing that the opponent is down.

If the game has not been knocked out using Step 〓〓, judge whether the game is over (Step〓〓), and if it is not finished, return to Step〓
The movement is read, and the following steps 〓〓、〓〓、〓〓、
The match continues by repeating 〓〓.

Next, the processing routine of each data in step 〓〓 will be explained.
6. Data input to the computer from the longitudinal position detection volume 68 is inputted to the computer by the A/D converter 100.
It is input as a hexadecimal digital value (00H to FFH), and the position of the lever 5 is determined based on the input digital value, and the moving speed of the lever 5 is determined based on the rate of change of the input digital value.

A processing routine after the longitudinal movement of the lever 5, that is, the stroke amount is detected by the longitudinal position detection volume 68, is shown in FIG. 11 and will be described.

First, the stroke amount is detected by the longitudinal position detection volume 68 (Step 〓〓).

The stroke amount input to the computer is a digital value, and a step is used to determine whether the amount of change in the digital value is 15 or more. If the amount of change is 15 or more, it is determined that a punch has been delivered. step
Proceed to step 33, and if it is 15 or less, it is not judged as a punch, and proceed to step 32, where it is determined whether the lever position is at the limit for producing a punch or not. If it is not at the limit, it returns to step If so, step 36
fly to

When it is determined that a punch has been delivered at step 〓〓, it is determined whether the punch is being delivered (step 〓〓), and if the punch is in progress, step 〓〓 is executed.
If it is immediately after a punch has been thrown, proceed to Step 〓〓, detect each data of the punch starting state (Step 〓〓), and use the same data to perform various punches (jab, hot punch, etc.). Set the possibility flag for (step 〓〓).

Setting this possibility flag is to predict in advance the type of punch that is likely to be a jab, straight, hook, or hot cut based on the value of each data of the lever position at the beginning of the punch. , a possibility flag of a possible punch is set in advance.

For example, if the stroke amount is 50H or more, there is a possibility of a jab, so the jab possibility flag is set, and if the lever position detected by the reflective optical sensors 77 and 78 is downward, there is a possibility of a top cut. Set the flag.

After setting the flags for possible punches in this way, we detect each piece of data that occurs when punches are subsequently thrown (Step 〓〓), and then use that data to set flags for punches that are no longer possible. is turned off one after another (step 〓〓).

For example, if there is no change amount of 4 or more to the left (or right) in the detection data of the swing angle from the swing angle detection volume 46 when punching right (or punching left), the hook possibility flag is turned off; If the lever 5 is already in the upper position, the upper cut possibility flag is turned off.

Then, in the next step 〓〓, the opponent's position and the position of the punch are compared and calculated, and it is determined whether or not to hit the opponent (step 〓〓). If not hit, jump to step 〓〓, and when to hit, Proceed to step 〓〓.

In step 〓〓, the type of punch is determined from the position where the punch hits the opponent and the state of the punch possibility flag, and the strength of the punch is determined from the amount of change in data (step 〓〓).

Based on the same result, a screen display is made (step 〓〓).

Next, a defense processing routine based on the detected value of the swing angle detection volume 46 will be explained with reference to FIG.

A/D converter 100 of swing angle detection volume 46
The detected digital value is set so that the limit value when the lever 5 is swung to the left is 00H, and the limit value when the lever 5 is swung to the right is FFH.

Therefore, 68H with lever 5 at approximately the center position
It is determined not to defend between ~98H, and the left side
It is determined that a left guard and a right guard will be performed between 30H and 68H and between 98H and DOH on the right side, respectively, and then between 00H and 30H on the left side and between 98H and DOH on the right side.
During FFH, it is judged as slipping.

Note that even in the guard state, if the rate of change is large, it is determined to be slip-spring.

The above judgment process will be explained based on FIG. 12. First, the detected value of the swing angle detection volume 46 is input as a digital value (Step 〓〓), and whether the input value is smaller than 68H or larger than 98H. Determine whether or not (Step〓〓〓〓〓〓, if it is between 68H and 98H, return to the original state, if it is less than 68H, proceed to the left defense route of Step〓〓, and if it is 98H or more, go to Step〓〓 〓 Proceed to the right defense route.

When progressing to the step〓〓 of left defense, the swing speed is detected by the amount of change, and if the amount of change is 8 or more and fast, it jumps to step〓〓 and is judged as left slipping, and when it is 8 or less and slow Furthermore, the input value
It is determined whether or not it is smaller than 30H (Step 〓〓). If it is larger than 30H, it is determined to be a left guard (Step 〓〓), and if it is smaller than 30H, it is determined to be left slipping (Step 〓〓).

Similarly, when progressing to the right defense step,
The swing speed is detected by the amount of change, and if the amount of change is 8 or more (step〓〓), it is determined that it is slipping to the right (step〓〓), and if it is less than 8, it is determined whether the input value is greater than DOH. If it is smaller than DOH, it is judged as a right guard (Step 〓〓), and if it is larger than DOH, it is judged as right slipping (Step 〓〓).

The above judgment results are displayed on the screen, and when guarding, the boxer corresponding to the player takes a defensive stance.

As described above, in this embodiment, by gripping the left and right levers 5, attacks such as hooks, straights, jabs, deep cuts, body blows, etc., and defenses such as left and right guards, slipping, etc., are actually performed in the same way as in actual boxing. Since you can play according to the movements of the players, combined with the screen display of CRT Display 4, you can enjoy a sense of realism and enjoy the excitement of actually competing.

Note that since the grip portion 6 of the lever 5 rotates, there is no unnaturalness when delivering the punch.

When the swinging support 3 swings from side to side, the background changes accordingly, and the background as seen from the viewpoint after the movement of the boxer corresponding to the player is displayed, creating a more realistic feeling. .

Effects of the invention The present invention allows the user to perform various punches and defenses by realizing the actual movements of boxing, so that the user can enjoy the tension and excitement unique to boxing.

In addition, the player's movements are judged and converted into real-time images using image processing, which also moves the screen, creating a sense of realism that can be interesting.
