It is composed of a small diameter portion M and a cam portion N whose diameter gradually increases in the rotation direction. The small-diameter portion M has a diameter that does not enter the ball feeding cylinder 22, and the cam portion N has a small-diameter dimension on one side adjacent to the small-diameter portion M, and a large-diameter dimension on the other side for at least one ball. ing. The direction of the plate cam 241 is reversed between FIGS. 3 and 4 for convenience of description.

The plate cam motor 242 is connected to the ball feeding cylinder 2
It is fixed upward to a motor mounting plate 222b mounted on the bottom of the second vertical portion 222. Then, the plate cam motor 242 rotates and the plate cam 241 makes one rotation in the direction indicated by the arrow in FIG. 4, so that the balls fed to the lower end of the vertical portion 222 are fed out one by one to the horizontal portion 221 side. Like that. That is, when the small-diameter portion M of the plate cam 241 starts rotating from a position (initial position) facing the ball feeding cylinder 22, the ball fed to the lower end of the vertical portion 222 comes into contact with the cam portion N to be horizontal. It is fed out to the unit 221.

As a result, the shielding plate 241b is connected to the plate cam sensor 243.
The initial position of the plate cam 241 is detected when the light emitting element and the light receiving element are blocked, and the number of rotations of the plate cam 241 is counted each time the initial position is detected.

The urging force applying means 25 is composed of a pair of rollers 251 and 252 arranged opposite to each other, and a pair of rollers for independently driving the pair of rollers 251 and 252 in the direction shown by the arrow in FIG. Motor (DC motor)
253 and 254. This pair of rollers 25
1 and 252 are configured by arranging rubber members 251b and 252b on the outer periphery of metal members 251a and 252a, and a part of each of the rubber members 251b and 252b.
2,213. Further, the roller motors 253 and 254 are fixed to motor mounting plates 214 and 215 mounted on the ball firing cylinder 21, respectively.

Thus, the pair of rollers 251 and 252
Rotates together with the pair of roller motors 253 and 254 when the ball firing cylinder 21 rotates around the axis,
By rotating the ball BL in the directions indicated by arrows while sandwiching the ball BL from both sides, an urging force in the firing direction (forward direction) is applied to the ball BL. The pair of rollers 251 and 252 can give the ball a firing speed corresponding to the peripheral speed, and can apply a spin to the ball fired from the ball firing cylinder 21 by giving a difference in the peripheral speed. .

That is, when the peripheral speed of the roller 251 is
By making the peripheral speed relatively higher than the peripheral speed of 52, a top spin (drive) can be applied to the ball, and conversely, a back spin (cut) can be applied to the ball. When the peripheral speeds of the rollers 251 and 252 are substantially the same, a rotational force is hardly applied to the ball,
It can be a so-called knuckle ball. Further, when the ball firing cylinder 21 is rotated around the axis by the rotation means 26 and the pair of rollers 251 and 252 are tilted, when a difference in peripheral speed is given to the rollers 251 and 252,
A ball with side spin can be obtained.

The rotating means 26 includes a driven gear 261 mounted on the outer periphery on the rear end side of the ball firing cylinder 21, a driving gear 262 meshing with the driven gear 261, and a driving gear 26.
And a launch cylinder rotating motor 263 for driving the rotation of the launch cylinder 2. The motor 263 for rotating the firing cylinder is the ball feeding cylinder 2
Motor mounting plate 221 mounted on the second horizontal portion 221
When the motor 263 rotates in both the forward and reverse directions, the ball firing cylinder 21 rotates around the axis.

A shielding plate 262a extending in the radial direction is fixed to a side surface of the driving gear 262. On the other hand, a sensor mounting plate 221b is mounted on the motor mounting plate 221a, and a shielding plate 262 is mounted on the sensor mounting plate 221b.
A rotation sensor 264 composed of a photo interrupter in which the positions of the light emitting element and the light receiving element are set so that a can pass through the gap is fixed. Thereby, the driving gear 262
The shield plate 262a attached to the sensor blocks the light emitting element and the light receiving element of the rotation sensor 264 to detect an initial position around the axis of the ball firing cylinder 21. The state in which the pair of rollers 251 and 252 is positioned in the up-down direction is defined as the initial position of the ball firing cylinder 21. Further, in this embodiment, the ball launching cylinder 21 is configured to rotate in the left and right directions within a range of 45 ° with respect to the initial position.

The swinging mechanism 27 includes a cylindrical support 271 fixed to the base 91 (FIG. 5) and the ball feeding cylinder 22.
, A rotating shaft 273 fixed to the bottom of the vertical portion 222 and mounted in the column 271 via a ball bearing 272, a driven gear 274 fixed to the upper portion of the rotating shaft 273, and a drive in which the driven gear 274 meshes A gear 275 and a firing unit swing motor 276 for driving the driving gear 275 to rotate are provided. The firing part swinging motor 276 is fixed to a motor mounting plate 221 c mounted on the vertical part 222 of the ball feeding cylinder 22, and the motor 276 rotates in both forward and reverse directions so that the rotation shaft 273 is centered. The ball firing unit 20 is rotated left and right to swing. Thereby, when the ball launching unit 20 is located in the front-back direction, a straight ball can be launched, and when the ball launching unit 20 is located diagonally, the ball is aimed at the left and right corners (corners) of the table tennis table 10. Will be able to fire. That is, the swing mechanism 27 can shoot not only a ball in the straight direction but also a ball in the cross direction.

At the lower end of the rotating shaft 273, a shielding plate 273a whose tip is upward is attached. On the other hand, the column 271 has a sensor mounting plate 27
1a is attached to the sensor mounting plate 271a.
A rotation sensor 277 composed of a photo interrupter in which the positions of the light emitting element and the light receiving element are set so that the shielding plate 273a can pass through the gap is fixed. As a result, the shield plate 273a attached to the rotation shaft 273 blocks the light emitting element and the light receiving element of the rotation sensor 277, thereby detecting the initial position of the ball emitting unit 20 in the rotation direction about the rotation axis 273. It has become. Note that a direction that is straight in the front-rear direction of the ping-pong table 10 is an initial position of the ball firing unit 20.

Further, a sensor mounting plate 271b is mounted on the column 271 at the rear outer periphery at the lower end thereof, and a swing angle sensor 278 composed of a variable resistor is mounted on the sensor mounting plate 271b. The rotation shaft 277 a of the swing angle sensor 278 is concentrically fixed to the rotation shaft 273 of the swing mechanism 27. As a result, the swing angle of the ball firing unit 20 is detected based on the voltage value output from the swing angle sensor 278 according to the amount of rotation of the rotating shaft 273, and the ball firing unit 20 is determined based on the initial position.
The swing angle can be controlled.

The angle changing means 28 comprises a guide plate 28 which is rotatably disposed at a firing port 211 at the tip of the ball firing cylinder 21.
1 and a guide plate motor 282 that rotationally drives the guide plate 281 in a direction that blocks the path of the ball fired from the firing opening 211. When the ball launching cylinder 21 is at the initial position around the axis, the guide plate 281 is pivotally supported on both sides of the base end at positions facing the outer periphery of the distal end of the launching port 211. That is, one of the base ends is pivotally supported by the projection 211a, and the other is pivotally supported by the rotating shaft 282a of the guide plate motor 282 fixed to the motor mounting plate 211b mounted at an appropriate location on the outer periphery of the firing port 211. .

When the ball launching cylinder 21 is at the initial position about the axis, the guide plate motor 282 is rotated by a predetermined amount to rotate the guide plate 281 so that the launching direction of the ball is obliquely upward. (That is, the launch angle of the ball can be changed). That is, as a result of the ball of the firing port 211 being directed upward by hitting the guide plate 281, it is possible to fire the ball in a mountain (parabola). The parabolic shape of the mountain can be adjusted by the amount of rotation (elevation angle) of the guide plate 281 and the firing speed of the ball. On the side facing the guide plate 281, an angle regulating plate 283 is arranged along the axial direction of the ball firing cylinder 21. Thus, when the firing angle of the ball with a high firing speed is greatly changed by the guide plate 281, the ball comes into contact with the angle regulating plate 283 and the size of the mountain is regulated, so that the ball does not easily go over the court 12. Like that.

Further, a shielding plate 281a is attached to the base end side of the guide plate 281 so as to extend rearward.
On the other hand, a sensor mounting plate 211c is mounted in the vicinity of the emission port 211, and a photo interrupter in which the positions of the light emitting element and the light receiving element are set so that the shielding plate 281a can pass through the gap. Is fixed. Thus, the shield plate 281a blocks the light emitting element and the light receiving element of the guide plate sensor 284 to detect the initial position of the guide plate 281. Note that the direction along the axial direction of the ball firing cylinder 21 is the initial position of the guide plate 281.

A firing angle sensor 285 made of a variable resistor is mounted on the sensor mounting plate 211c, and its rotating shaft 285a is fixed to a projection 281b of a guide plate 281 which is coaxial with the projection 211a. ing. Thus, the amount of rotation of the guide plate 281 is detected based on the voltage value output from the firing angle sensor 285, and the firing angle of the ball can be controlled based on the initial position.

Next, a description will be given of a moving mechanism section 90 for moving the ball firing section 20 in the left-right direction. That is, as shown in FIG.
Are mounted on a pair of guides 92a and 92b fixed to the bottom of a base 91 on which the ball is mounted, and on a table 202 fixed in a housing 200 (FIG. 1) covering the ball firing unit 20. Guide rail 93 disposed along the left and right direction in which the guides 92a and 92b are slid.

At the center in the left-right direction behind the base 91,
The shielding plate 91a is attached so as to extend downward. On the other hand, a sensor mounting plate 93a protruding rearward from the center in the left-right direction of the guide rail 93 has a central base made of a photo interrupter in which the positions of the light emitting element and the light receiving element are set so that the shielding plate 91a can pass through the gap. Stand sensor 97
Has been fixed. Thereby, the initial position of the base 91, that is, the initial position of the ball firing unit 20 in the left-right direction is detected by the shielding plate 91a blocking the light emitting element and the light receiving element of the central base sensor 97. I have. The center position of the table 202 in the left-right direction is set as the initial position of the ball firing unit 20, and the movement in the left-right direction is controlled based on this initial position.

The sensor mounting plates 93b, 9 projecting rearward from the leftward and rightward positions (both directions relative to the player) from the center of the guide rail 93.
A left base sensor 98 and a right base sensor 99 composed of a photo interrupter in which the positions of the light emitting element and the light receiving element are set so that the shielding plate 91a can pass through the gap are fixed to 3c. Thereby, the shielding plate 91a blocks the light emitting element and the light receiving element of the left base sensor 98 or the right base sensor 99, thereby moving the base 91 in the left-right direction, that is, moving the ball firing unit 20 in the left-right direction. The limit position is detected so that the ball firing unit 20 does not overrun the movement limit position.

The ball collecting section 30 is a ball that has been shot from the ball shooting section 20 onto the court 12 and hit by the player and has fallen on the floor, and has fallen from the left and right edge sides of the table tennis table 10 (so-called sideline sides). The ball and the ball dropped from the rear edge side (the so-called end line side) of the table tennis table 10 are collected on the ball firing unit 20 side, and the defective ball deformed by the player accidentally stepping on his / her foot will be described later. Bad ball collection box 33

The floor collecting section 31 is formed so as to include a region where the player plays.
Floor portion 311, a second floor portion 312 connected to the table tennis table 10 side of the first floor portion 311, and a second floor portion 31
2 at the center of the ball. The second floor portion 312 is separated into a left floor portion 312a and a right floor portion 312b on both left and right sides of the ball collecting portion 313, and both the left floor portion 312a and the right floor portion 312b have a lower ball collecting portion 313 side. It is arranged in an inclined state so as to become. Further, the ball collecting section 313 is arranged in a state of being inclined such that the court 14 side is lowered.

As a result, the balls dropped on the first floor 311 roll on the first and second floors 311 and 312 and are collected in the ball collecting section 313. Further, the balls collected in the ball collecting unit 313 are moved up in a cylinder described later by the ball pumping means 37 and transferred to the left collecting unit 32. In addition to the normal spherical ball, a partially recessed defective ball that has rolled to the ball collecting section 313 is transferred to the left collecting section 32 by the ball pumping means 37.

A plurality of (five in the figure) rail bodies arranged in parallel with the left collecting part 32 having a height lower than the table tennis table 10 and being inclined so that the rear collecting part 33 side is lower. 321, and a receiving plate 322 having a substantially C-shaped vertical section disposed below the plurality of rail bodies 321 and arranged so as to be inclined such that the rear recovery unit 33 side is lowered. The plurality of rail bodies 321 are arranged at intervals slightly smaller than the diameter of the ball. Therefore, a normal ball can be rolled between the adjacent rails 321, while a defective ball, which is partially dented by being stepped on by a player or the like, falls onto the receiving plate 322 from between the adjacent rails 321. Will be sorted out.

As a result, the normal ball rolls while straddling the adjacent rail body 321 and is transferred to the rear collecting section 33 side, and the concave defective ball collected by the floor collecting section 31 is Falls on the receiving plate 322 from between the rails 321 to be rolled, and rolls on the receiving plate 322 (or a ball that does not roll hits a ball that falls later).
It is transferred to a receiving plate 332 of the rear recovery unit 33 which will be described later.
Note that the ends of the plurality of rail bodies 321 and the receiving plate 322 intersect with the rail bodies and the receiving plate of the rear recovery unit 33 so that the balls can be transferred.

A plurality of rear collecting portions 33 are arranged at a height lower than that of the ping-pong table 10 and at an angle so that the right side (the lower side in FIG. 6) of the court 14 is lower. 5) rail body 331 and the plurality of rail bodies 33

And a defective ball collection box 334 disposed below the right edge of the receiving plate 332.

The plurality of rails 331 are connected to the left collecting section 32.
Similarly, they are arranged at intervals slightly smaller than the diameter of the ball. Therefore, a normal ball can be rolled between the adjacent rails 331, while a defective ball, which is partially depressed by being stepped on by a player or the like, falls onto the receiving plate 332 from between the adjacent rails 331. Will be sorted out. The normal ball relay box 333 has an opening on the housing 200 side, and is disposed in an inclined state so that the housing 200 side is lowered.

Since the recessed defective ball has been recovered by the floor recovery unit 31, most of the recessed ball is received from the clearance between the rails 321 adjacent to the left recovery unit 32.
Although the ball on the rail body 321 rolls on the rail body with the same portion serving as a rolling axis, when the portion intersecting with the rolling axis is concave, the ball It will not fall from the gap of the body 321. Therefore, for a defective ball that has not fallen from the gap of the rail body 321, the rear recovery unit 33 is provided orthogonal to the left recovery unit 32, so that the rolling shaft is changed to a right-angled position and a concave is formed. The waist part will be opposed between the rail bodies 322,
The defective ball falls from the gap between the rail bodies 322.

As a result, the normal ball can be
21, 331, the defective ball passed to the normal ball relay box 333,
On the other hand, it falls on the receiving plate 322 or 332 and is transferred to the defective ball collection box 334.

52.

The front end of the receiving plate 352 is located above the defective ball collection box 334. In addition, most of the recessed defective balls are in the floor collection unit 3
1 has been collected through the rear collecting section 33, most of the ball should have been collected in the defective ball collection box 334. Those that did not fall from the gap between the adjacent rail bodies 331 of the rear recovery part 33 due to the direction of the part are changed by changing the direction of the recessed part with respect to the rail body 351 by the vertical recovery part 35 and the adjacent rail body 351 is changed.
Will fall from the gap.

As a result, the normal ball rolls while straddling the adjacent rail body 351 and moves to the rear
The defective ball that has been transferred to the sixth side and has been recessed falls from the gap between the adjacent rail bodies 351 onto the receiving plate 352 and is collected in the defective ball collection box 334. Note that the ends of the plurality of rails 351 and the receiving plate 322 intersect with the rails and the receiving plate of the horizontal recovery unit 36 so that the balls can be transferred.

The horizontal collection section 36 has a plurality of (four in the figure) rail bodies 361 arranged so as to be inclined such that the left side is lower, and the right side is lower below the plurality of rail bodies 361. It has a receiving plate 362 arranged so as to be inclined so as to form a normal ball collection box 363 arranged below the left end edges of the plurality of rail bodies 361. The interval between the plurality of rails 361 is set in the same manner as the rails 361 and the like.
While rolling to the left while straddling No. 1, the defective defective ball drops from the gap between the adjacent rail bodies 361 onto the receiving plate 362. The same applies to the case where the ball is collected from the right collecting unit 34 and guided to the vertical collecting unit 35 and the horizontal collecting unit 36. The collected ball from the right collecting unit 34 is connected to the left collecting unit 32 and the rear. Since the ball has not passed through the collecting section 33, the defective ball from the right collecting section 34 is sorted by the vertical collecting section 35 and the horizontal collecting section 36.

Next, an example of the operation of the table tennis apparatus according to the present invention configured as described above will be described. First, an initialization operation of each mechanism of the table tennis apparatus will be described with reference to a flowchart shown in FIG. First, the power switch is
When N is determined, a board check is performed to determine whether each component such as a CPU functions normally (step S1), and then each component is initialized (step S3). Next, the ball firing unit moving motor 296a is rotationally driven to move the ball firing unit 20 in the left-right direction (step S5),
It is determined whether or not the ball launching unit 20 is located at the center of the ping-pong table 10 after a predetermined time has elapsed (step S7).
The rotation drive of 6a is stopped (step S9).

If the determination in step S7 is negative, it is determined whether or not the ball launcher 20 is located at the left end or right end of the ping-pong table 10 (step S11). Launch unit 20 is table tennis table 10
(Step S13), and then returns to Step S7. If the determination is negative in step S11, it is determined that the ball launching unit 20 is moving to the center of the ping-pong table 10, and the process returns to step S7 to execute the subsequent operations.

Next, the swing angle in the left-right direction with respect to the ball shooting unit 20 is set (step S15), and the ball shooting unit 20 is rotated in the left-right direction. Here, it is determined whether there is any abnormality in the swing angle and the swing sensor 277 (step S17). If the determination is affirmative, the firing angle of the firing port 211 is set (step S19).
Thereafter, the guide plate 281 of the firing port 211 is rotated by an angle corresponding to the set firing angle, and it is determined whether the firing angle, the guide plate sensor 284, and the firing angle sensor 285 are normal (step S21). If the determination is affirmative, initial setting of the score display section 41, the image display section 42, an unillustrated electric lamp, etc. is performed (step S23).
Subsequently, initialization of the cold cathode tubes 181 to 184 is performed (step S25). When a negative determination is made in step S17 and step S21, error processing (for example, display of an abnormal portion on the image display unit 42) is performed (step S27, step S29).

Next, the game operation will be described with reference to the flowchart shown in FIG. First, it is determined whether or not there is any abnormality in the initialization operation of each unit described above (step S31). If the determination is affirmative, a demo screen before the start of play is displayed on the image display unit 42 (step S3).
3). Then, it is determined whether or not a coin has been inserted into the coin insertion slot CE of the control box 70 (step S35). If the determination is affirmative, the game variables (the number of remaining balls, the launch angle, and the like) are initialized. (Step S3
7).

Next, it is determined whether or not a predetermined game course among the elementary course, the intermediate course, and the advanced course has been selected (step S39). Is set (step S41). When a negative determination is made in step S31, error processing (for example, display of an abnormal location on the image display unit 42) is performed (step S43).
The game cannot be started. If the determination in step S39 is negative, the determination is repeatedly performed until the game course is selected.

When the contents of the game are set in step S41, the ball pumping means 37 of the ball collecting section 30,
38 operates (step S45), and the ball stirring means 236 of the ball supply unit 23 operates (step S4).
7) The cold-cathode tubes of a predetermined emission color among the cold-cathode tubes 181 to 184 of the court 14 are turned on immediately before the ball is fired (step S49). Then, the ball is fired from the ball firing unit 20 toward the court 12 (step S5).
1) The position of the ball hit by the player on the court 14 is detected, and a scoring process is performed (step S53). Then, it is determined from the count value of the plate cam sensor 243 of the ball feeding means 24 whether or not the specified number of balls have been fired from the ball firing unit 20 (step S).
55) If the determination is affirmative, game end processing is performed (step S57). If a negative determination is made in step S55, the process returns to step S45, and the subsequent operations are repeatedly performed.

Next, steps S45 and S4 shown in FIG.
7, S49, S51, S53 and S57 will be described in order with reference to the flowcharts of FIGS. Steps S45, S47, S49, S
Each of the operations 51, S53, S55, and S57 is repeatedly executed at a predetermined cycle, for example, every 1/60 second. However, the flowcharts of FIGS. 15 to 20 focus on each operation for convenience of explanation. Has been explained.

First, the operation of the ball pumping means 37, 38 of the ball collecting section 30 in step S45 shown in FIG. 14 will be described with reference to the flowchart shown in FIG. Since the ball pumping means 37 and 38 have the same operation, the ball pumping means 37 will be described here as an example. First, the rotation of the stirring / feeding motor 379 in the forward direction is started (step S71), and the stirring / feeding motor 3
It is determined whether or not 79 has made one rotation (step S7).
3). If the determination is affirmative, the rotation number is counted up (step S75), and the rotation timer is subsequently counted up (step S77).

Thereafter, it is determined whether or not the rotation timer has reached a specified number (step S79). If the determination is affirmative, it is determined whether or not the rotation number of the stirring / feeding motor 379 has reached the specified number. It is determined (step S81). When the determination is affirmed, the error count is cleared (step S83). That is, when the stirring / feeding motor 379 is operating normally without the ball clogging in the vicinity of the ball stirring unit 377, and the game is in progress, step S71 is performed.
After that, the operation of step S83 is repeatedly executed. If the determination is negative in step S73, the process proceeds to step S77. If the determination is negative in step S79, the process returns to step S73, and the subsequent operations are repeatedly performed until the rotation timer reaches the specified number.

On the other hand, if a negative determination is made in step S81, the rotation of the stirring / feeding motor 379 is stopped, the rotation timer is cleared (step S85), and the stop timer is newly counted up (step S87). ). The case where the determination is negative in step S81 is a case where the ball is clogged near the ball stirring unit 377 and the stirring / feeding motor 379 is not rotating normally. Then, it is determined whether or not the stop timer has reached the prescribed number (step S89). If the determination is affirmative, the reverse rotation of the stirring / feeding motor 379 is started (step S9).
1). That is, the reverse rotation of the stirring / feeding motor 379 is performed to eliminate the ball clogging that occurs near the ball stirring unit 377. Step 8
If a negative determination is made in step 9, the process returns to step S87, and the determination is repeatedly performed until the stop timer reaches the specified number.

When the stirring / feeding motor 379 is rotated in the reverse direction in step S91, the stop timer is cleared and the rotation timer is counted up (step S91).
93) Subsequently, it is determined whether or not the rotation timer has reached a specified number (step S95). If the determination is affirmative, the rotation of the stirring / feeding motor 379 is stopped, the rotation timer is cleared (step S97), and then the stop timer is counted up (step S99). Then, it is determined whether or not the stop timer has reached the specified number (step S).
101), if the determination is affirmative, errors are counted up (step S103). Step S101
If the determination is negative in step, the process returns to step S99, and the determination is repeatedly performed until the stop timer reaches the specified number.

Subsequently, it is determined whether or not the error count has reached a prescribed number (for example, "3") (step S1).
05) If the determination is negative, the process returns to step S71, and the subsequent operations are repeatedly executed. That is, when the clogging of the ball is eliminated by rotating the agitating / feeding motor 379 in the reverse direction, the steps from step S71 to step S83 are repeatedly executed thereafter. Also, from step S85 to step S103
If the ball clogging is not resolved by the repetitive operations up to the specified number of times (for example, three times), the determination in step S105 is affirmative, and error processing (for example, display of the ball clogging on the image display unit 42) Is performed (step S107). In this case, since the ball is not fired from the ball firing unit 20 after a predetermined time, for example, the progress of the game is stopped when the ball is no longer fired.

Next, the operation of the ball stirring means 236 of the ball supply unit 23 in step S47 shown in FIG. 14 will be described with reference to the flowchart shown in FIG.
First, rotation of the stirring motor 234 in the hopper is started (step S121). Next, the rotation timer is counted up (step S123), and thereafter, it is determined whether or not the rotation timer has reached a specified number (step S12).
5). When the determination is affirmative, the rotation of the stirring motor 234 in the hopper is stopped and the rotation timer is cleared (step S127), and subsequently, the stop timer is counted up (step S129). Then, it is determined whether or not the stop timer has reached the specified number (step S13).
1) If the determination is affirmative, the process returns to step 121, and the subsequent operations are repeatedly executed. If the determination in step S125 is negative, the process returns to step S123, and the determination is repeatedly performed until the rotation timer reaches the specified number. If a negative determination is made in step 131, the process returns to step S129, and the determination is repeatedly performed until the stop timer reaches the specified number.

Next, the lighting operation of the cold cathode tubes 181 to 184 in step S49 shown in FIG.
This will be described based on the flowchart shown in FIG. First, difficulty processing is performed according to the game course, the score, and the number of remaining balls (step S141). That is, a low degree of difficulty the game course (e.g., beginner course and intermediate course) cold cathode tubes of the plurality of areas of the region E ₂ to E ₅ coat 14 in order to easily get a score when the selected lights while the high degree of difficulty the game course (e.g., advanced courses) cold cathode tubes of any one region of the regions E ₂ to E ₅ coats 14 to difficult to obtain a score when is selected A difficulty level process is performed so as to be turned on. Also, for example, even when a game course with a low difficulty level is selected, if the score exceeds a predetermined value or the number of remaining balls is less than a predetermined value, it is difficult to obtain a score. one of the ₂ to E ₅ 1
The difficulty processing is performed so that the cold cathode tubes in the two areas are turned on.

Before the ball is fired from the ball firing unit 20, it is determined whether the difficulty level is low (step S).
143), if the determination is affirmative, the cold cathode tubes 182,1 in the two left (or right) regions E ₃ , E ₅ (or E ₂ , E ₄ )
84 (or 181, 183) are simultaneously turned (step S145), the determination is negative (i.e., when there is a high degree of difficulty) any one of the four regions E ₂ to E ₅
Cold cathode tubes 181, 182, 183 or 184
Is turned on (step S147).

Next, the ball firing operation of the ball firing unit 20 in step S51 shown in FIG. 14 will be described with reference to FIG.
This will be described based on the flowchart shown in FIG. First, it is determined whether or not the specified number of balls have been fired from the ball firing unit 20 (step S161). The ball type and the ball speed of the ball to be fired next are determined according to the number of balls (step S163). That is, when the difficulty of the game is high, for example, the type of the ball such as drive and cut, the degree of spin, and the like are frequently changed, and the firing speed is also increased. In addition, when the difficulty level of the game is low, for example, the type of the ball and the degree of the spin are not changed so much.
The firing speed is also reduced. If the determination in step S161 is negative, the operation shifts to the operation in step S53 shown in FIG.

Next, the firing position of the ball to be fired next is determined according to the difficulty of the game (step S1).
65). That is, when the difficulty level of the game is high, for example, the ball shooting unit 20 sets the court 1 on the court 14 corresponding to the position where the ball falls on the court 14 bounced back by the player.
4 in the left-right direction.

That is, when it falls on the second area E ₂ or the fourth area E ₄ on the right side of the court 14, the second detection signal output from the pair of microphones 192, 193 or 196, 197 causes the second signal. ball launching unit 20 is judged to be dropped onto the region E ₂ or the fourth region E ₄ table tennis 10
Is moved to, for example, the center position or the right end position of the right half. When the player falls on the third area E ₃ or the fifth area E ₅ on the left side of the court 14, the pair of microphones 194, 19
5 or the signal output from the 198 and 199 the third region E ₃ or the fifth region E ₅ that has fallen is discriminated on the ball firing unit 20 is the left half of the example the center position and the left edge of the table tennis 10 Moved to position. This movement is controlled by the number of pulses supplied to the firing unit moving motor 96a.

If the difficulty level of the game is low, the position of the ball launching section 20 may be fixed at the center position of the table tennis table 10 regardless of the position of the ball dropped on the court 14 returned by the player. The table tennis table 10 is fixed at the left end position or the right end position.

Next, the firing angle of the ball to be fired next is determined according to the difficulty of the game (step S1).
67). That is, when the degree of difficulty of the game is high, for example, the firing angle is frequently changed, or the firing rate of the ball at the peak is reduced, and the firing rate of the ball at the lower position is increased. When the difficulty level of the game is low, for example, the firing angle is not frequently changed, or the firing rate of the mountain ball is increased and the firing rate of the low-position ball is reduced.

Next, the firing direction (straight direction or cross direction) of the ball to be fired next is determined according to the degree of difficulty of the game (step S169). That is,
When the difficulty of the game is high, for example, the launch direction of the ball is frequently changed. When the difficulty level of the game is low, for example, the launch direction of the ball is not changed much.

The rotation speeds of the pair of roller motors 253 and 254 of the urging force applying means 25 are quickly changed by PWM control (pulse width modulation control). 263 is driven by the supplied voltage of a predetermined number of pulses to rotate the ball firing unit 20 by a predetermined angle in the forward direction or the reverse direction, and set so that the ball type and the ball speed determined in step S163 become the same. Is performed (step S171). In addition, the firing unit moving motor 96a is driven by the supplied voltage of a predetermined number of pulses to move the ball firing unit 20 to the left or right predetermined position, and to move to the ball firing position determined in step S165. It is set (step S173). Note that the type of ball referred to in steps 163 and 171 refers to a type that is changed by the degree of spin applied by the urging force applying unit 25 and the rotating unit 26.
The ball speed changed by the angle and the angle changing means 28
And the like, which are generated by the above, can be included in the ball type.

Further, the guide plate motor 282 of the angle changing means 28 is driven until the voltage value output from the firing angle sensor 285 reaches a predetermined value, and the guide plate 281 is rotated by a predetermined angle, and is determined in step S167. It is set to the launch angle of the performed ball (step S175). Further, the launching unit swing motor 276 of the swing unit 27 is driven until the voltage value output from the swing angle sensor 278 reaches a predetermined value, and the ball firing unit 20 rotates leftward or rightward by a predetermined angle. Is moved and set to the launch direction of the ball determined in step S169 (step S17).
7).

When the coach mode selection switch CS of the control box 70 is turned on, step 16 is executed.
The operations of 3 to 169 are performed by the switch PS _{1 of the} area selection switch PS installed in the control box 70.
In addition, processing is performed in accordance with a signal output when any one of PS ₆ to PS ₆ is turned on. Even if the coach mode selection switch CS is turned on, if none of the area selection switches PS is turned on, the ball is fired under programmed conditions.

Next, it is determined whether or not the timing of firing the ball (for example, firing once every two seconds) has arrived (step S179). The rotation is started, and the plate cam 241 is rotated accordingly (step S18).
1). If the determination is negative in step S179,
The determination is repeatedly performed until the firing timing comes.

Then, it is determined whether or not the plate cam 241 has made one rotation (step S183). If the determination is affirmative, a firing sound (for example, a pseudo sound when a ball is hit with a racket) is generated (step S183). Step S185). Thereafter, the rotation of the plate cam motor 242 is stopped, and accordingly, the rotation of the plate cam 241 is stopped (step S187). If the determination is negative in step S183, the plate cam 2
It is determined whether or not a predetermined time has elapsed from the start of rotation of 41 (step S189), and if the determination is affirmative, error processing (for example, display of a blocked ball) is performed (step S189).
191). If the determination is negative in step S189, the process returns to step S183, and the subsequent operations are repeatedly executed.

Next, the detection of the drop position of the ball and the score processing in step S53 shown in FIG. 14 will be described with reference to FIG.
This will be described based on the flowchart shown in FIG. First, it is determined whether or not the ball has been fired from the ball firing unit 20 (step S221). If the determination is affirmative, it is determined whether or not the previous detection signals output from the microphones 190 to 199, which are vibration sensors, have been cleared. Is determined (step S223). Then, if the determination is affirmed, it is determined whether or not the ball hit back by the player has fallen on the court 14 (step S225). If the determination is negative in step S223, the determination is repeatedly performed until the detection signal is cleared, and the signal is ignored even if the next detection signal is output from the microphones 190 to 199 during that time. Has become.

That is, if the determination is affirmative in step S221, a flag is set, and the microphone 1 is set only when the ball falls on the court 14 while the flag is set.
While the detection signal output from 90 to 199 is taken in by the score addition means, once the detection signal is taken in by the score addition means, the flag falls, and the ball falls again on the court 14 due to bouncing or the like. Even if the detection signal is output, the detection signal is ignored and is not taken into the score adding means.

However, the previously shot ball is dropped on the court 14 immediately before the next ball is shot, for example, by being hit back in a mountain shape, and bounces off and re-engages the court 14 immediately after the next ball is shot. In the case of falling up, the points are overlapped and added due to the bounce of the previous ball, and the point is not added in the next ball, which causes a disadvantage. For this reason, the detection signal due to the first bounce is held for a certain period of time (for example, 0.5 seconds), and even if the next detection signal is output within the holding time, the signal is ignored. I have. This allows the previously fired ball to enter the court 14 immediately before the next ball is fired.
Even in a case where the player falls down and bounces and falls again on the court 14 immediately after the next ball is shot, the points are not overlapped and added.

More specifically, as shown in FIG. 21 (a), the _first ball is fired from the ball firing unit 20 at time t ₁ and a flag F is set. ₂ to 2-shot eyes of the ball and that is firing the flag F is set. In this case, as shown in the figure, even if the first ball hit back on the court 14 continues to bounce on the court 14 before the second ball is fired, the first bounce time t _1a And the flag F falls, the detection signal due to the later bounce is not taken into the score adding means.

However, as shown in FIG. 21 (b), the ball bounces on the court 14 at time t _1b immediately before the ball is fired, and again at time t _1c immediately after the second ball is fired. Assuming that the ball bounces on the court 14, the flag F due to the launch of the ball is in a state of rising immediately before the bounce at the time t _1b , and the flag F due to the launch of the ball is in the state immediately before the second bounce at the time t _1c. Therefore, both detection signals are taken into the score adding means.

In this case, as shown in the figure, the detection signal is held for, for example, 0.5 second from the first bounce time t _1b , and a gate is provided during this time so that a new detection signal is not accepted. If the time when the holding is cleared is after the second bounce time t _1c of the ball, the detection signal by the first bounce of the ball is taken in by the score adding means, but the detection signal by the second bounce is taken. Will not be.

Note that the second ball usually bounces on the court 14 at time t _2a after the detection signal of the first ball is cleared, and the detection signal due to the bounce is scored. It will be taken into the addition means. Therefore, by appropriately setting the holding time of the detection signal with respect to the firing interval of the ball, it is possible to eliminate the inconvenience that the score is repeatedly added for the same ball. Note that the above 0.5 second is an example, and the time may be set to a time corresponding to the maximum value of the bound time or a time slightly longer than the maximum value.

Returning to FIG. 19, if the determination is negative in step S225, it is determined whether a predetermined time has elapsed (step S227), and if the determination is affirmative, FIG.
When the determination is denied, the process returns to step S225, and the determination is repeatedly performed until a predetermined time has elapsed. If the determination is affirmative in step S225, the ball hit back by the player is
₂ to 81 to 184 lit area E of whether dropped to E ₅ is determined (step S229), the high score and determination is affirmative (e.g., 2 points) is added to the score so far On the other hand, a sound effect such as music for awarding a score is output for a fixed time (step S231). In this embodiment, when the cold cathode fluorescent lamp falls on the boundary between the lit area and the non-lit area, the scoring process is performed as if the cold cathode ray tube fell into the lit area. ing.

Next, the cold-cathode tube in the area where the ball has fallen is blinked for a certain time in order to obtain the illumination effect,
The cold cathode tubes in the other areas are all turned on for a certain period of time (step S233), and the added score is displayed on the score display unit 41, and the score display unit 41 is blinked for a certain time to score. Appealed (step S23
5).

If the determination is negative in step S229, the normal score (for example, one point) is added to the score so far, while a sound effect such as music that recognizes the score is output for a certain period of time. (Step S237). Then, the added score is displayed on the score display section 41, and the score display section 41 blinks for a certain period of time, thereby appealing that the score has been obtained (step S239). Then, step S2
When the blinking operation of the score display section 41 in 35 or step S239 is completed, all the cold cathode tubes 181 to 184 are turned off (step S241).

Next, the game end processing in step S57 shown in FIG. 14 will be described with reference to the flowchart shown in FIG. First, the motor 234 for stirring in the hopper of the ball firing unit 20 and the motors 253 and 25 for rollers are used.
4. The rotation of the firing tube rotation motor 263, the firing unit swinging motor 276, the guide plate motor 282, and the firing unit moving motor 96a are stopped (step S261), and the image display unit 42 displays a demonstration screen regarding the end of the game. Is displayed (step S263). The demo screen for the end of the game includes updating of the high score, displaying the final score, and the like.

Then, the launching portion moving motor 96a of the moving means 90 is driven to rotate, and the ball launching portion 20 is moved to the table tennis table 1.
0 (Step S26)
5) The guide plate motor 282 of the angle changing unit 28 is driven to rotate, and the guide plate 281 is returned to the initial position (step S267). The ball firing unit 20 is returned to the initial position in the swinging direction (step S26)
9).

Thereafter, it is determined whether or not a predetermined time has elapsed (step S271).
9 is stopped (step S273). If the determination in step S271 is negative, the determination is repeatedly performed until a certain time has elapsed.
