Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
239 words
A microfiche storage and display unit, comprising: storage means for storing a plurality of microfiche, each microfiche having a plurality of frames spaced in X horizontal direction rows and Y vertical direction columns, said storage means including selection means for selecting any one of said plurality of stored microfiche; display means including a viewing screen and having an optical axis for displaying upon said viewing screen a selected one of the frames of the selected one of said microfiche; X-Y positioning means for positioning said one selected frame of said one selected microfiche within said optical axis of said display means, said X-Y positioning means including X-Y positioning air jet means for carrying in a jet of air said one selected microfiche in said X horizontal direction and in said Y vertical direction within said X-Y positioning means to a position selected so that the selected frame is positioned within said optical axis; access air jet means for carrying in a jet of air said one selected microfiche into said X-Y positioning means from said storage means; return air jet means for carrying in a jet of air said one selected microfiche back into said storage means from said X-Y positioning means; transporter means for guiding said one selected microfiche between said storage means and said X-Y positioning means when said one selected microfiche is carried therethrough by said access air jet means or said return air jet means.
Claim 2
Dependent Claim
239 words
A microfiche storage and display unit, comprising: storage means for storing a plurality of microfiche, each microfiche having a plurality of frames spaced in X horizontal direction rows and Y vertical direction columns, said storage means including selection means for selecting any one of said plurality of stored microfiche; display means including a viewing screen and having an optical axis for displaying upon said viewing screen a selected one of the frames of the selected one of said microfiche; X-Y positioning means for positioning said one selected frame of said one selected microfiche within said optical axis of said display means, said X-Y positioning means including X-Y positioning air jet means for carrying in a jet of air said one selected microfiche in said X horizontal direction and in said Y vertical direction within said X-Y positioning means to a position selected so that the selected frame is positioned within said optical axis; access air jet means for carrying in a jet of air said one selected microfiche into said X-Y positioning means from said storage means; return air jet means for carrying in a jet of air said one selected microfiche back into said storage means from said X-Y positioning means; transporter means for guiding said one selected microfiche between said storage means and said X-Y positioning means when said one selected microfiche is carried therethrough by said access air jet means or said return air jet means.
Claim 3
Dependent Claim
139 words
The microfiche storage and display unit of claim 1 wherein said X-Y positioning means further includes: Y positioning means including Y actuator means for establishing the distance said one selected microfiche will travel in said Y vertical direction in increments equal to the vertical spacing of said frames of said microfiche; X positioning means including; X actuator means for establishing the distance said one selected microfiche will travel in said X horizontal direction in increments equal to the horizontal spacing of said frames of said microfiche; X positioning block means slideably mounted in said Y positioning means to move in said X horizontal direction and coupled to said X actuator means for establishing the distance in said X horizontal direction that said one selected microfiche is moved within said X-Y positioning means by said X-Y positioning air jet means.
Claim 4
Dependent Claim
52 words
The microfiche storage and display unit of claim 2 in which said Y positioning means further includes a member coupled to said Y actuator means and having opposing front and back fingers for holding said one selected microfiche and for moving in a freely sliding Y vertical direction within said transporter means.
Claim 5
Dependent Claim
46 words
The microfiche storage and display unit of claim 2 wherein said access air jet means includes a plurality of substantially downwardly directed A1 air jets arranged along said transporter means for carrying said one selected microfiche downwardly from said storage means into said X-Y positioning means.
Claim 6
Dependent Claim
39 words
The microfiche storage and display unit of claim 4 wherein said X-Y positioning air jet means includes a plurality of substantially horizontally directed A2 air jets for carrying said one selected microfiche horizontally against said X positioning block means.
Claim 7
Dependent Claim
94 words
The microfiche storage and display unit of claim 5 wherein said return air jet means includes: a plurality of substantially horizontally directed B1 air jets for carrying said one selected microfiche horizontally away from said X positioning block means; a plurality of substantially upwardly directed C1 air jets for carrying said one selected microfiche upwardly away from said Y positioning means and upwardly toward said storage means; and, a plurality of substantially upwardly directed C2, C3 air jets arranged along said transporter means for carrying said one selected microfiche upwardly into said storage means.
Claim 8
Dependent Claim
50 words
The microfiche storage and display unit of claim 6 wherein said return air jet means further includes an additional plurality of substantially horizontally directed B2 air jets for carrying said one selected microfiche horizontally away from said X positioning block means and into the influence of said C1 air jets.
Claim 9
Dependent Claim
38 words
The microfiche storage and display unit of claim 7 in which said substantially horizontally directed A2, B1 air jets both have downwardly directed components for carrying said one selected microfiche to the bottom of said Y positioning means.
Claim 10
Dependent Claim
41 words
The microfiches storage and display unit of claim 8 in which said substantially upwardly directed C1 air jets have horizontally directed components for carrying said one selected microfiche into substantial vertical alignment with said storage means while within said transporter means.
Claim 11
Dependent Claim
38 words
The microfiche storage and display unit of claim 9 in which said substantially horizontally directed B2 air jets carry said one selected microfiche away from said X positioning block means and into substantial alignment with said transporter means.
Claim 12
Dependent Claim
89 words
The microfiche storage and display unit of claim 10 further including: keyboard means for generating coded information signals in response to the actuation of the keys thereof; translator means for translating said coded information signals for coupling fluidic signals to said X actuator means, said Y actuator means and said plurality of air jets; and, pneumatic pressure source means for providing said fluidic signals under control of said translator means for displaying the selected one of the frames of the selected one of said microfiche upon said viewing screen.
