Further, the upper edge portions of the front and rear holding pieces 10 </ b> B and 10 </ b> C are attached to both ends of a handle 10 </ b> F that is gripped when the cassette 10 is carried or taken into and out of the storage chamber 7 of the apparatus body 3.

  A positioning hole 10G is formed at one front and rear intermediate position on the left side of the bottom plate 10A and two front and rear positions on the right side. On the other hand, as shown in FIG. 7, three positioning pins 43 are attached to the upper surface of the movable receiving plate 12 at positions corresponding to the three positioning holes 10 </ b> G, respectively. The corresponding positioning holes 10G and the positioning pins 43 are engaged with each other so that the cassette 10 is positioned on the movable receiving plate 12.

  As shown in FIGS. 15 and 16, the cassette 10 has a shape that allows the receiving piece 15 to pass through the bottom plate 10A and a part of the holding piece 10B on the front side, and restricts the drop-out of the ball, at the left side of the front end portion of the cassette 10. A gate portion 10H is formed.

  In the gate portion 10H, as shown in FIG. 5, due to the inclination of the movable receiving plate 12, the receiving piece 15 whose tip portion is rotated downward is rotated around the swing shaft 9 in the clockwise direction in FIG. Accordingly, a ball (not shown) moving on the gate portion 10H can be scooped up from the cassette 10 by the receiving piece 15 and taken out.

  Two guide protrusions 44 and 45 are attached to the upper surface of the bottom plate 10A of the cassette 10 from the inner side of the front holding piece 10B to the rear side. These guide protrusions 44 and 45 guide the moving direction of the ball in the cassette 10 due to the inclination of the movable receiving plate 12.

  Next, when the ball is set to a designated position on the billiard table using the billiard setting apparatus 1 configured as described above, the set arm 6 is first brought down as shown in FIG. The center position of the set ring 4 on the billiard table is determined by adjusting the direction of the apparatus main body 3 and the length of the set arm 6.

  Next, as shown in FIG. 17, with the set arm 6 standing up, the cassette 10 containing the ball B (shown in phantom) is dropped into the accommodation chamber 7 of the apparatus body 3 from above and set. . In FIGS. 17 to 20, a part of the billiard ball setting apparatus 1 described above is schematically omitted or simplified.

  FIG. 18 shows a state in which the cassette 10 is held on the movable receiving plate 12 in the storage chamber 7. In this state, the movable receiving plate 12 is inclined to the front side, and is also inclined to the left side along the inclined axis X as shown in FIG. 6, but as described above, the movable receiving plate 12 protrudes from the upper surface of the movable receiving plate 12. Since the positioning pin 43 (see FIG. 7) and the positioning hole 10G (see FIGS. 15 and 16) formed in the bottom plate of the cassette 10 are engaged, the cassette 10 is fixed at a predetermined position on the movable receiving plate 12. Yes.

  As shown in FIG. 19, when the switch 9 is turned on by the operation unit 11 or the remote control to drive the swing shaft 9 and the set arm 6 is rotated in the direction of the arrow, the receiving piece 15 is positioned at the gate portion 10H. The ball B is scooped up from below, and the ball B is held between the upper surface and the flat portion 21B of the relay plate 21.

  With the upward rotation of the receiving piece 15, the movable receiving plate 12 is tilted backward around the tilt axis X by the biasing force of the return spring 40, and the ball B following the ball B moves to the rear of the cassette 10. .

  After the backward tilting of the movable receiving plate 12 stops at the position restricted by the adjusting screw 41, the ball B taken out from the cassette 10 by the receiving piece 15 is rotated around the swing shaft 9 of the set arm 6. Then, it moves from the receiving piece 15 onto the relay plate 21 in the take-out passage 8.

  Then, as shown in FIG. 20, when the set arm 6 is further rotated to the lying position, the ball B is accelerated by passing over the inclined portion 21C formed on the front end side of the relay plate 21, and the set arm 6 is accelerated. Passed to 6.

  As shown in FIG. 21, the ball B moved onto the set arm 6 is guided by the ball guide surfaces 6F and 6G formed on the left and right sides of the ball B and falls into the set ring 4, and the billiard table S The ball B is set at the center position of the upper set ring 4.

  In the present embodiment, the set arm 6 is slightly inclined toward the tip side at the lying position, and the ball B can be reliably sent to the set ring 4 using its own weight.

  However, when the ball B passes through the inclined portion 21C of the relay plate 21, it is accelerated here. Therefore, when the inclination angle of the inclined portion 21 is set to be large, the set arm 6 is placed horizontally at the lying position. Even so, the set ring 4 can be reached by the inertia of the ball B.

  The swinging shaft 9 is reversed by the operation unit or remote control operation, the set arm 6 is returned to the standing position, and the hand ball is practiced against the ball B (target ball) on the billiard table S. When the set arm 6 returns to the standing position, the receiving piece 15 pushes down the interlocking piece 42 provided on the movable receiving plate 12 against the urging force of the return spring 40, so that the movable receiving plate 12 is again shown in FIG. As shown, it tilts forward about the tilt axis X, and as a result, the subsequent ball B moves to the front end side of the cassette 10.

  At this time, if the movable receiving plate 12 is tilted forward from the state shown in FIG. 20, the succeeding ball B on the front side in FIG. 20 moves forward to create a space at the rear of the cassette 10. Since the plate 12 is inclined toward the front side of the figure along the inclination axis X, the ball B located at the back of the cassette 10 due to the forward and backward tilting of the movable receiving plate 12 is shown in FIGS. It moves sequentially along the guide ridges 44 and 45 so as to fill the space.

  In this manner, each time the set arm 6 is repeatedly laid down, a new ball B can be taken out from the cassette 10 and set in the same position on the billiard table S.

  In this embodiment, as described above, the rotation position of the swing shaft 9 is detected by these limit switches, and the stop position of the geared motor 18 shown in FIG. 8 is controlled. Alternatively, the rotation position of the swing shaft 9 may be detected using a non-contact sensor such as an optical sensor.

  Further, the set ring 4 is held with respect to the set ring holding plate 30 (see FIG. 12) so that a slight relative displacement in the vertical direction is possible, the set arm 6 falls down, and the lower end surface of the set ring 4 is the billiard table. It is also possible to detect the vertical displacement that occurs when abuts on the sensor with a sensor attached to the set ring holding plate and stop the geared motor 18.

  Next, a method for using the image ring 5 will be described. The image ring 5 is used when practicing to hit a ball (target ball) set on a billiard table from a direction different from a linear direction connecting the center of the pocket and hit it and drop it in the pocket.

As shown in FIG. 22, when the target ball at the center position O ₁ of the set ring 4 is aimed from the straight line N direction and applied to the target ball and dropped into a pocket in the straight line M direction, the image ring 5 is used. The rotation around the set ring 4 is adjusted so that the center position O ₂ is located on the straight line M, and the practice of aiming at the center O ₂ of the image ring 5 with the hand ball is repeated.

Then, leaving the set was specific sphere to the position of the set ring 4, along with a set arm 6, settling 4 and the image ring 5 is erected, virtual object ball centered at the center position O ₂ (images balls) When the hand ball is thrown toward the center position O ₂ , the target ball collides with an actual target ball at the center position O ₁ when the hand ball comes to the center position O _2. It is bounced in the direction of the straight line M passing through O ₁ and O ₂ and falls into the pocket.

  FIG. 25 is a schematic structural diagram of the billiard ball setting apparatus A1, and in this embodiment, the swing link A5 is fixed to the swing shaft 9 to which the set arm 6 is connected.

  The swing link A5 is connected to one end of the connection link A6 so as to be rotatable with respect to each other by a connection shaft A7. The other end of the connection link A6 is rotatably connected to a crankshaft A11 attached to a first crank disk A10 attached to the output shaft A9 of the rotational drive source A8.

  The rotational drive source A8 used here is composed of a geared motor with output shafts A9 projecting on both left and right sides thereof, and the first crank disc A10 is attached to the right end of the output shaft A9. In the figure, it is arranged on the back side of the rotational drive source A8. Further, the swing link A5 and the connection link A6 are also arranged close to the right side inside the apparatus main body A3, similarly to the first crank disk A10.

  Further, the rotation of the output shaft A9 is controlled by a limit switch (not shown) so that the rotation drive source A8 stops every half rotation in the clockwise direction in the figure, and the set arm 6 falls down every half rotation. The swing shaft 9 is swung so as to be in a position (position in the figure) and a standing position (position in FIG. 23).

  In the present embodiment, the rotation drive source A8 can be controlled by an operation button or a remote controller of an operation unit (not shown) provided in the apparatus main body A3, and the output shaft A9 is halfway every time the operation button is pressed. By rotating, the set arm 6 falls and stands up alternately.

  The swing link A5, the connecting link A6, and the first crank disc A10 are used as components of a saddle crank mechanism that converts the rotational motion of the output shaft A9 into the swing motion of the swing shaft 9.

  On the other hand, a second crank disc A12 is attached to the left end of the output shaft A9, and one end of a connection link A14 is rotatably connected to the crankshaft A13. In the drawing, the second crank disk A12 is shown overlapping the first crank disk 10, but the second crank disk 12 and the connecting link A14 are on the left side inside the apparatus main body A3. It is arranged close to.

  The other end of the connection link A14 is connected to one end of a pusher A15 disposed at the rear end portion of the apparatus main body A3 so as to be rotatable with respect to each other by a connection shaft A16. The pusher A15 is pivotally supported at the intermediate position of the apparatus main body A3 by a support shaft A17. The rear end of the pusher A15 swings up and down in conjunction with the rotation of the output shaft A9.

  Although the detailed shape of the portion near the rear end of the pusher A15 is omitted, it is arranged at the center position in the width direction of the apparatus main body A3, and when this portion swings upward, the bottom surface of the cassette A2 It invades from the slit formed in the bottom and protrudes from the upper surface of the lower inclined guide A2n.

  In the present embodiment, an arcuate guide A18 is provided on the back side of the receiving piece 15. The arcuate guide A18 prevents the ball B on the gate portion A2e of the cassette A2 from being caught by the back surface of the receiving piece 15 when the receiving piece 15 rotates inside the cassette A2.

  The operation of the billiard ball setting apparatus A1 configured as described above will be described. The structure of the arm mounting piece 14, the receiving piece 15, and the set arm 6 and their functions are omitted because they are the same as those in the second embodiment. Here, the ball B on the set arm 6 from the cassette A2 is omitted. Only the extraction operation will be described.

  In FIG. 26, as indicated by the solid line in FIG. 26, in the state where the set arm 6 is in the upright posture, the pusher A15 is immersed inside the apparatus main body A3, and in this state, the cassette A2 containing the ball B therein. Wear.

  At this time, the leading ball B descending to the gate portion A2e (see FIG. 25) of the cassette A2 is positioned directly above the receiving plate 15 descending to the lower side of the cassette A2 and is in contact with the relay plate 21. . At this time, the arcuate guide A 18 provided on the receiving plate 15 is retracted into the apparatus main body 3.

  When the output shaft A9 is rotated clockwise (in the direction of the arrow) from this state, the swing shaft 9 rotates clockwise through the first crank disk A10, the connecting link A6, and the swing link A5. The leading ball B is scooped up by the receiving piece 15 as indicated by the phantom line, and is transferred from the receiving piece 15 to the relay plate 21.

  On the other hand, along with the rotation of the output shaft A9, the pusher A15 swings clockwise around the support shaft A17 via the second crank disk A12 and the connecting link A14, and the rear end portion enters the cassette A2. And protrudes from the upper surface of the lower inclined guide A2n.

  By this operation, the lower part of the ball B stacked up and down along the rear wall plate A2h of the cassette A2 is pushed forward as indicated by the phantom line in FIG. The movement of B is prevented from being hindered.

  As shown in FIG. 25, when the set arm 6 is rotated to the lying position, the ball B taken out from the cassette A2 by the receiving piece 15 moves to the set arm 6 side by its own weight, and thereafter, the billiard ball described above. Like the setting device 1, it falls into the set ring 4 and is set at a predetermined position on the billiard table S.

  When the ball B is thus set at the predetermined position, the output shaft A9 is further rotated halfway clockwise to return the set arm 6 to the standing position shown in FIG. Note that the rear end of the pusher A15 is retracted into the apparatus main body A3 in the process in which the set arm 6 falls from the position of the phantom line in FIG. 26 to the position in FIG. By repeating the operation described above, the ball B accommodated in the cassette A2 can be repeatedly set at a predetermined position on the billiard table S.
