2. Description of the Prior Art The former ball game devices like pinball machines etc. have allowed only two dimensional movement of the ball as the ball moves on a plain surface, whereas the ball and net game device of the present invention achieves three dimensional movement of the ball as the ball is projected to, bounded on and dropped through the net board so that any player can enjoy such three dimensional playing factors as aiming at, projecting to and expecting to bound or drop in a specified mesh of prize hole with passing down through the net board by the ball.
BRIEF SUMMARY OF INVENTION ball and net game device has horizontally several levels of net board whose mesh is just large enough to let the ball pass down through, an uppermost net board having a projecting mechanism free to change .its projection angle, each level of said net board having such a detecting mechanism as a microswitch 'at a prescribed position, said detecting mechanism acted only by the ball dropped in a mesh of said prescribed position to let a prize ball discharging mechanism open and to let a slide-film projecting mechanism project a slide film.
The operation of the presentinvention is such that any game-player can enjoy to aim the ball projectile at a specified prize mesh and toexpect a chance of the slide-films projected on a screen as well as to gain some prize balls each time the ball drops in said specified mesh and that the player can sit in a chair to play a game without any mental and physical fatigue.

DESCRIPTION OF THE PREFERRED EMBODIMENT A ball and net game device comprises a main body 1 which has horizontally several levels of net boards 2 2a 2b 2c 2d etc.
A screen part 3 is mounted vertically at the rear an upper part of the main body 1.
A slide-film projector M can throw a picture on the screen part 3, as shown in FIG. 8.
A ball projecting mechanism 4 is mounted on the top plane of the main body 1.
against the ball projecting mechanism 4.
A ball 7 can be projected by the ball projecting mechanism 4 to the uppermost net board 2, as shown in H6. 5.
A mesh 8 of the net boards 2 2a 2b 2c 2d etc. is as large'as just enough to let the ball 7 pass through.
A guide conduit9jsmounted at the lowest position of the main body 1 to receive the ball 7 dropping.
A conveyor 10 will feeds the ball 7 from the guide conduit 9 to a prize ball tank 11.
Microswitches 12 12 are set under some mesh places of the net board 2 and under one mesh place of each level of the net boards 2a 2b 2c 2d etc.
When a pushing plate 13 of the microswitch 12 is pushed by the ball 7 dropped in the mesh 8 of the prescribed mesh place (FIG. 6), an electromagnet 14 will be operated through a relay 14a and a prize ball discharging mechanism 15 will be opened to discharge a prescribed number of balls lying in the prize ball tank 11 down to a hopper 16.
The ball 7 is fed on from the hopper 16 to a conveyer 17, from which the ball 7 is further fed out to a ball receiving conduit 18 adjacent to the ball projecting mechanism 4. I
A motor 19 drives the conveyer 10.
Another motor 20 will drives the conveyer 17.
I A microswitch 12 will'be acted to operate the slidefilm projector M and many kinds of slide-films will be projected on the screen 3 at a short time as they are exchanged in order. 1 i
The ball 7 which passed down through the net board 2 will drop and bound at random from the upper net board to the lower net board.
After dropping passage through the levels of net boards 20 2b 2c 2d etc. the ball 7 will be received by the guide conduit 9.
If the ball 7 pushes the pushing plate 13 of the microswitch 12 during said dropping passage, the microswitch 12 is acted to feed out the prescribed number of the balls in the prize ball tank 11 at each time of pushing and also to project orderly exchanging slide-films on the screen part 3.
The ball projecting mechanism 4 is composed of a projecting tube 22 which is inserted by a projecting rod 21 and a fan-shaped guide rail 24 which guides a leg part 23 having the projecting tube 22 en bloc.
The projecting tube 22 can be moved along the fanshaped guide rail 24 at a selected projecting angle to the net board 2 and can be freely adjusted.
A spring 25 will act at the projecting rod 21.
A knob 26 is fixed at the projecting rod 21.
Ball receiving parts27 27 stand on said mesh place of prize hole of the net board 2 to catch the ball 7 projected.
To explain a game played by the ball and net game device of the present invention, when the balls 7 7 are at first set in the ball receiving conduit 18, they will be fed to the projecting place before the projecting mechanism 4 one by one.
Then the player moves the projecting mechanism 4 to aim at the ball receiving part 27 of prize hole and projects the ball 7.
When the ball 7 drops in the prize hole directly or during passing and bounding down through the net boards, the prize ball discharging mechanism 15 and the slide-film projector M will be operated as mentioned above.
When the balls 7 7 drop in the prize hole continuously, switching operation of the microswitch 12 will result one by one through a known electrical circuit.
