Abstract
Abstract An apparatus of the type having a display panel with game feature carriers and other indicating devices is provided in which the display panel is formed as a liquid crystal display. Circuit means are provided for selectively controlling the elements of the liquid crystal display so that three modes of control are employed, the display being different in each of the three modes. In one mode, certain of the display devices are continuously sequentially operated, and in a second mode a random control of certain display devices is provided, the last occurring indication in the second mode being held in the third mode of operation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A control and indicator apparatus, comprising a first group of a plurality of display devices, first and second counters, a clock generator connected to apply clock pulses to said first and second counters, shift register means, means for selectively applying the output of said counters to said shift register means, and decoder means coupled to determined stages of said shift register means for controlling said display devices, said means for selectively applying the outputs of said counters to said shift register means comprising first and second AND-gate means connected to the outputs of said first and second counters respectively, means for selectively operating said first and second AND-gate means, OR-gate means coupling the output of said second AND-gate means to said shift register means, a plurality of third AND-gate means coupling the output of said first ANDgate means to said OR-gate means and means for selectively opening the AND-gate means of said plurality of AND-gate means.
Claim 2
Dependent Claim
156 words
A control and indicator apparatus, comprising a first group of a plurality of display devices, first and second counters, a clock generator connected to apply clock pulses to said first and second counters, shift register means, means for selectively applying the output of said counters to said shift register means, and decoder means coupled to determined stages of said shift register means for controlling said display devices, said means for selectively applying the outputs of said counters to said shift register means comprising first and second AND-gate means connected to the outputs of said first and second counters respectively, means for selectively operating said first and second AND-gate means, OR-gate means coupling the output of said second AND-gate means to said shift register means, a plurality of third AND-gate means coupling the output of said first ANDgate means to said OR-gate means and means for selectively opening the AND-gate means of said plurality of AND-gate means.
Claim 3
Dependent Claim
81 words
The control and indicator apparatus of claim 1, further comprising a group of second AND-gate means having inputs connected to the output of said second counter and outputs connected said OR-gate means, and further comprising means responsive to said means for selectively opening the AND-gate means of said first mentioned plurality of AND-gate means for opening the AND-gate means of said second group of AND-gate means when the corresponding AND-gate means of said first mentioned group of AND-gate means are closed.
Claim 4
Dependent Claim
40 words
The control and indicator apparatus of claim 1, further comprising random control means for inhibiting the application of said clock pulses to said first counter, and means responsive to the count of said second counter for resetting said first counter.
Claim 5
Dependent Claim
66 words
The control and indicator apparatus of claim 1, further comprising a second group of a plurality of display devices, a source of coded signals of random frequency, signal transforming means connected to said clock generatOr for converting said coded signals to a lower frequency, and means for controlling the display devices of said second group of display devices with the output of said signal transformer means.
Claim 6
Dependent Claim
128 words
In an apparatus of the type having a display panel with game feature carriers, the improvement wherein said game feature carriers are mechanically fixed liquid crystal means positioned to provide rotating displays, and further comprising additional mechanically fixed liquid crystal means on said panel, and circuit means connected to the liquid crystal means of said game feature carriers and to said additional liquid crystal means for controlling displays thereon, said circuit means comprising means for controlling said liquid crystal means of said game feature carriers to produce rotating displays only during first determined times, means for controlling said liquid crystal means of said game feature carriers during second determined times to produce fixed displays, and means for controlling said additional liquid crystal means during said second determined times.
Claim 7
Dependent Claim
128 words
In an apparatus of the type having a display panel with game feature carriers, the improvement wherein said game feature carriers are mechanically fixed liquid crystal means positioned to provide rotating displays, and further comprising additional mechanically fixed liquid crystal means on said panel, and circuit means connected to the liquid crystal means of said game feature carriers and to said additional liquid crystal means for controlling displays thereon, said circuit means comprising means for controlling said liquid crystal means of said game feature carriers to produce rotating displays only during first determined times, means for controlling said liquid crystal means of said game feature carriers during second determined times to produce fixed displays, and means for controlling said additional liquid crystal means during said second determined times.
Claim 8
Dependent Claim
70 words
The apparatus of claim 5, wherein said additional liquid crystal means comprise first liquid crystal means arranged to produce a numerical display, and second liquid crystal means arranged to produce a matrix display and said circuit means comprises means during said second determined times for selectively controlling said first and second liquid crystal means, and further comprising means for displaying different colors on the liquid crystal means of said apparatus.
