Abstract
Abstract A vehicle-driving game where the street, a first group of cars and a second group of cars are pictured on separate transparent discs. A lamp behind the discs superimposes all three images, and additionally the image of a drive-controlled car, on a screen in front of the driver. Each of the three discs is separately driven, the speed of the road-bearing disc being controlled by the driver, and the speed of the two car-bearing discs being controlled by a differential gear mechanism between the road disc and each of the car discs, and a programmed control motor for each car disc. The image on the screen shows two groups of cars, each moving at a speed independent of the other group but determined through the differential by the relative speed of the roadway and the programmed controller. A photosensitive element on the driver-controlled car controls a circuit to a sounder which sounds when the image of one of the cars on one of the discs overlaps that of the driver-controlled car and blocks the light rays from the lamp.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
306 words
A vehicle-driving game, comprising: a multirotary disc mechanism comprising a first rotary disc made of a lighttransmitting material, on which a figure of a street is circumferentially drawn, a second rotary disc made of a lighttransmitting material, on which a figure of at least one vehicle is drawn in the area corresponding to said figure of a street on said first rotary disc; a differential gear means including an input rotary member adapted to be rotated in the direction opposite to the rotational direction of said first rotary disc, the rotational speed of said input gear being automatically varied, an output rotary member associated with said input rotary member and having an axis adapted to be revolved around the axis of said first rotary disc at a speed corresponding to the difference between the rotational speeds of said first rotary disc and said input rotary member and in the same direction as that one of said first rotary disc and said input rotary member the rotational speed of which is greater; and means for connecting said axis of said output rotary member to said second rotary disc so that upon revolution of said axis said second rotary disc is rotated; a lamp; a model vehicle; means for supporting said lamp and said model vehicle at the opposite sides of said multirotary disc mechanism; means for moving said model relative to said first rotary disc crosswise of said figure of a street drawn thereon; means including a screen on which the image of said model vehicle and the image of said figure of a street and said at least one vehicle on said first and second rotary discs are projected so as to be seen by the player of said game; and means operated by the player to change the rotational speed of said first rotary disc.
Claim 2
Dependent Claim
306 words
A vehicle-driving game, comprising: a multirotary disc mechanism comprising a first rotary disc made of a lighttransmitting material, on which a figure of a street is circumferentially drawn, a second rotary disc made of a lighttransmitting material, on which a figure of at least one vehicle is drawn in the area corresponding to said figure of a street on said first rotary disc; a differential gear means including an input rotary member adapted to be rotated in the direction opposite to the rotational direction of said first rotary disc, the rotational speed of said input gear being automatically varied, an output rotary member associated with said input rotary member and having an axis adapted to be revolved around the axis of said first rotary disc at a speed corresponding to the difference between the rotational speeds of said first rotary disc and said input rotary member and in the same direction as that one of said first rotary disc and said input rotary member the rotational speed of which is greater; and means for connecting said axis of said output rotary member to said second rotary disc so that upon revolution of said axis said second rotary disc is rotated; a lamp; a model vehicle; means for supporting said lamp and said model vehicle at the opposite sides of said multirotary disc mechanism; means for moving said model relative to said first rotary disc crosswise of said figure of a street drawn thereon; means including a screen on which the image of said model vehicle and the image of said figure of a street and said at least one vehicle on said first and second rotary discs are projected so as to be seen by the player of said game; and means operated by the player to change the rotational speed of said first rotary disc.
Claim 3
Dependent Claim
92 words
The vehicle-driving game of claim 1, wherein said multirotary disc mechanism comprises a first rotary disc made of a light-transmitting material, on which a figure of a street having a plurality of lanes is drawn, and a plurality of second rotary discs made of a light-transmitting material, on each of which a figure of at least one vehicle is drawn in the area corresponding to one of said lanes of the street on said first rotary disc, and wherein said differential gear means is provided for each one of said second discs.
Claim 4
Dependent Claim
46 words
The vehicle-driving game of claim 1, wherein said model vehicle is provided with a photosensitive element adapted to receive the light emitted by said lamp and produce an output signal when said light is intercepted by said figure of a vehicle on said second rotary disc.
Claim 5
Dependent Claim
27 words
The vehicle-driving game of claim 3, further including means operable in response to said signal to produce a sound similar to that produced upon collision of vehicles.
Claim 6
Dependent Claim
32 words
The vehicle-driving game of claim 3, further including means operable in response to said signal to stop the rotation of said first rotary disc for a predetermined relatively short period of time.
Claim 7
Dependent Claim
40 words
The vehicle-driving game of claim 5, further including means for counting the number of rotations of said first rotary disc for a predetermined period of time and indicating the counted number as the distance that said model vehicle has run.
Claim 8
Dependent Claim
31 words
The vehicle-driving game of claim 3, further including means for counting the number of signals produced by said photosensitive element during a predetermined period of time and indicaTing the counted number.
