Abstract
Abstract A rotatable assembly includes a plurality of writing devices which are selectably moveable into and out of writing position. As the assembly rotates, the writing devices in the writing position describe concentric patterns on a recording medium. The selective movement of the writing devices may be controlled by an array of sensing elements such as light sensors. These may be located on the assembly and may be selectively energized, as the assembly rotates, in response to a smaller stationary group of energy emitting elements located next to the assembly.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
120 words
In combination: means responsive to a signal for emitting energy; movable means comprising a plurality of energizable loads and a like plurality of energy sensing means, each coupled to a different one of said loads; means for creating relative motion between said energy emitting means and said movable means for causing said emitting means to be presented serially opposite the different ones of said sensing means; and signal producing means coupled to said emitting means for causing said emitting means to be energized while opposite certain of said sensing means, said certain of said sensing means being responsive to energy emitted by said energy emitting means for causing said loads with which they are coupled to become and remain energized.
Claim 2
Dependent Claim
120 words
In combination: means responsive to a signal for emitting energy; movable means comprising a plurality of energizable loads and a like plurality of energy sensing means, each coupled to a different one of said loads; means for creating relative motion between said energy emitting means and said movable means for causing said emitting means to be presented serially opposite the different ones of said sensing means; and signal producing means coupled to said emitting means for causing said emitting means to be energized while opposite certain of said sensing means, said certain of said sensing means being responsive to energy emitted by said energy emitting means for causing said loads with which they are coupled to become and remain energized.
Claim 3
Dependent Claim
51 words
The combination as set forth in claim 1, wherein said movable means is responsive to a reset signal for causing said energized loads to become unenergized and further including means producing said reset signal only after said emitting means has been presented opposite each of said plurality of energy sensing means.
Claim 4
Dependent Claim
89 words
The combination as set forth in claim 2 wherein said energy emitting means is an energizable light emitting source and wherein said energy sensing means are light sensing means responsive to light from said light emitting source for entering a state of conduction and where there is further included an energy source coupled between said light sensing means and said loads wherein when one of said light sensing means is made conductive, the one of said loads coupled thereto becomes and remains energized until said reset signal is produced.
Claim 5
Dependent Claim
86 words
The combination as set forth in claim 1 wherein said motion creating means creates rotary motion between said energy emitting means and said movable means and wherein said movable means are responsive to a reset signal for causing said energized loads to become unenergized and further including means producing said reset signal only after said emitting means has been presented opposite each of said plurality of energy sensing means and thereafter said movable means has made at least one complete revolution relative to said emitting means.
Claim 6
Dependent Claim
130 words
A plurality M of selectable energy emitting means; movable means comprising a plurality N of energizable loads and a like plurality of energy sensing means, each sensing means being coupled to a different load, where M and N are integers and N is greater than M; means creating relative motion between said energy emitting means and said movable means for serially presenting groups of M energy sensing means opposite said M energy emitting means so that in a group each of said sensing means is opposite a different emitting means; means energizing selected ones of said emitting means while each of said groups is opposite said emitting means for activating the ones of said sensing means opposite said selected emitting means for causing said loads coupled thereto to be energized.
Claim 7
Dependent Claim
130 words
A plurality M of selectable energy emitting means; movable means comprising a plurality N of energizable loads and a like plurality of energy sensing means, each sensing means being coupled to a different load, where M and N are integers and N is greater than M; means creating relative motion between said energy emitting means and said movable means for serially presenting groups of M energy sensing means opposite said M energy emitting means so that in a group each of said sensing means is opposite a different emitting means; means energizing selected ones of said emitting means while each of said groups is opposite said emitting means for activating the ones of said sensing means opposite said selected emitting means for causing said loads coupled thereto to be energized.
