Abstract
Abstract The specification discloses a gaming machine comprising a projector for projecting an endless film of horse races. The film is divided into four subframes a selected one of which is brought to a screen by means of a system of tilting mirrors. The selection of subframe is made at random twice in each race to give unpredictable variations of the race shown; a coin mechanism is provided so that bets can be made and winnings paid out in accordance with the outcome of the race.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
172 words
A game apparatus, comprising; an optical projection means for proJecting images carried on a cinematograph film having a plurality of different film sequences disposed side by side across the lateral width of the film, each of said film sequences extending longitudinally of the film, driving means for moving the film along a longitudinal path through said projection means, optical means for deflecting the projected images onto a screen, means for producing electrical signals actuated by movement therepast of predetermined points along the length of the film, motor-driven random selection means independent of said driving means and responsive to said electrical signals for actuating said optical means to project a randomly selected one of the plurality of film sequences onto the screen, means for initially selecting by choice respective film sequences of the plurality of film sequences before actuation of said driving means, and means for indicating the correspondence between said respective choice selected film sequences and said randomly selected film sequence finally determined at the cessation of operation of the game apparatus.
Claim 2
Dependent Claim
172 words
A game apparatus, comprising; an optical projection means for proJecting images carried on a cinematograph film having a plurality of different film sequences disposed side by side across the lateral width of the film, each of said film sequences extending longitudinally of the film, driving means for moving the film along a longitudinal path through said projection means, optical means for deflecting the projected images onto a screen, means for producing electrical signals actuated by movement therepast of predetermined points along the length of the film, motor-driven random selection means independent of said driving means and responsive to said electrical signals for actuating said optical means to project a randomly selected one of the plurality of film sequences onto the screen, means for initially selecting by choice respective film sequences of the plurality of film sequences before actuation of said driving means, and means for indicating the correspondence between said respective choice selected film sequences and said randomly selected film sequence finally determined at the cessation of operation of the game apparatus.
Claim 3
Dependent Claim
37 words
A game apparatus according to claim 1, wherein said optical means includes independently rotatable reflecting members controlled by said random selection means so as to project only the selected one of the film sequences towards the screen.
Claim 4
Dependent Claim
27 words
A game apparatus according to claim 2, wherein said optical means further includes fixed reflector means to project images from said rotatable reflecting members onto the screen.
Claim 5
Dependent Claim
29 words
A game apparatus according to claim 2, wherein said optical means further includes solenoids for positioning said rotatable reflecting members in response actuation thereby of said random selection means.
Claim 6
Dependent Claim
40 words
A game apparatus according to claim 4, wherein said random selection means includes microswitches electrically connected to said solenoids and a disc connected to a constant speed motor, said disc having formations sensed by said microswitches for controlling said solenoids.
Claim 7
Dependent Claim
17 words
A game apparatus according to claim 5, wherein said formations are annular grooves sensed by said microswitches.
Claim 8
Dependent Claim
38 words
A game apparatus according to claim 5, wherein the initial section of a film sequence by said means for choice selecting activates said constant speed motor, and said driving means for moving the film are energized independently thereof.
Claim 9
Dependent Claim
101 words
A game apparatus according to claim 4, wherein said film has at least four subframes arranged in at least two pairs side by side to represent a plurality of sequential events, said rotatable reflecting members including two movable mirrors, one of said mirrors is in either of two alternative positions to respectively project towards the other movable mirror one pair or the other pair of said subframes, and said other movable mirror is in either of two alternative positions to respectively project towards the screen one or the other subframe of said pair of subframes reflected by said one movable mirror.
Claim 10
Dependent Claim
39 words
A game apparatus according to claim 8, wherein said at least four subframes represent different sequential events, said subframes having similar events prior to said electrical signals being produced to project a coherent sequence of events onto the screen.
Claim 11
Dependent Claim
29 words
A game apparatus according to claim 1, wherein said means for producing electrical signals includes a microswitch mounted adjacent said projector to sense said predetermined point along said film.
