Abstract
Abstract A microprocessor-controlled microfiche viewer which is adaptable for displaying microfiche having any format. The viewer calls up selected microfiche images in either a sequential mode or a random mode. In the sequential mode a carrier table follows a default sequence, and is cued by a keyboard control, by a dual-tone audio cueing signal that is received over a telephone line or from a tape player, or by a digital signal from an RS-232 port. In the random mode, particular images are selected by moving the carrier table in desired directions with directional keys, or by providing the coordinates of an image to the microprocessor. Image coordinates are entered manually at the keyboard, by dual-tone audio signals from a telephone line or a tape player, or by data from the RS-232 port. Means are provided for generating audio tones for recording cue signals on one track of an audio tape while playing back an audio accompaniment pre-recorded on the other channel, in order to synchronize the selection of images with an audio commentary. Also provided are means for holding the microfiche flat in the focal plane of the projection lenses, and a system of marking either the fiche to be viewed or a blank formatting fiche to adapt the viewer to the proper format.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
228 words
A control system for controlling movements of a carrier for a microfiche having images arranged in substantially any format to position said microfiche and a selected image at a focal point of an optical system for display by the optical system of said selected image on such microfiche, said focal point is substantially fixed and said carrier is movable to any location with an X-Y coordinate system, and wherein the microfiche bears format data identifying placement of said selected image and including X-motor means for moving the carrier and microfiche in an X direction and Y-motor means for moving the carrier and microfiche in a Y direction, comprising: memory means for storing digital data representing predetermined patterns of X and Y movements, address input means for receiving digital, audio, and manual inputs and in response generating digital address data indicative of movements to be performed, format input means for reading the format data on the microfiche and generating in response digital format data indicative of movements to be performed, cue input means for receiving digital, audio, and manual cue inputs and in response generating digital cue signals for initiating movements, processing means for receiving digital signals and data from said memory means, address input means, format input means, and cue input means and generating analog signals to control said X and Y motor means and said optical system.
Claim 2
Dependent Claim
228 words
A control system for controlling movements of a carrier for a microfiche having images arranged in substantially any format to position said microfiche and a selected image at a focal point of an optical system for display by the optical system of said selected image on such microfiche, said focal point is substantially fixed and said carrier is movable to any location with an X-Y coordinate system, and wherein the microfiche bears format data identifying placement of said selected image and including X-motor means for moving the carrier and microfiche in an X direction and Y-motor means for moving the carrier and microfiche in a Y direction, comprising: memory means for storing digital data representing predetermined patterns of X and Y movements, address input means for receiving digital, audio, and manual inputs and in response generating digital address data indicative of movements to be performed, format input means for reading the format data on the microfiche and generating in response digital format data indicative of movements to be performed, cue input means for receiving digital, audio, and manual cue inputs and in response generating digital cue signals for initiating movements, processing means for receiving digital signals and data from said memory means, address input means, format input means, and cue input means and generating analog signals to control said X and Y motor means and said optical system.
Claim 3
Dependent Claim
21 words
A system as in claim 1, including means for receiving such audio cue and audio address inputs from a telephone line.
Claim 4
Dependent Claim
52 words
A system as in claim 2, including means for receiving such audio cue and audio address inputs from a magnetic tape, and further comprising means for recording such audio cue and address inputs on such magnetic tape and means for transmitting such audio cue and audio address inputs on a telephone line.
Claim 5
Dependent Claim
66 words
A system as in claim 1, wherein said format input means includes for reading column markers and code markings in a header portion of such microfiche, such column markers indicating the locations of columns of images on such microfiche, and such code markings being located between two of such column markers and indicating formats of columns and rows in which images are arranged on such mircofiche.
Claim 6
Dependent Claim
27 words
A system as in claim 4, wherein such code markings are divided into at least two segments, each segment being located between two of said column markers.
Claim 7
Dependent Claim
31 words
A system as in claim 4, wherein such code markings further indicate the location of at least one image that is not arranged in such columns and rows on such microfiche.
Claim 8
Dependent Claim
35 words
A system as in claim 4, wherein such code markings indicate a format of images corresponding to a predetermined pattern of X and Y movements for which digital data are stored in said memory means.
Claim 9
Dependent Claim
84 words
A system as in claim 1 wherein: the analog signals generated by said processing means in response to digital cue signals from said cue input means corresponds to digital address data from said address input means when such digital address data are received by said processing means prior to receiving such digital cue signals, and the analog signals correspond to digital data from the memory means at times other than when such digital address data are received prior to receiving such digital cue signals.
Claim 10
Dependent Claim
43 words
A system as in claim 1, wherein said optical system includes lenses mounted in a movable turret, and said processing means generates analog signals to move such turret to select a desired lens in response to format data from said format input means.
Claim 11
Dependent Claim
43 words
A system as in claim 1, wherein said optical system includes a lamp and said processing means generates analog lamp signals to power such lamp, the lamp being relatively bright while images are being displayed and relatively dim during X and Y movements.
Claim 12
Dependent Claim
45 words
A system as in claim 10, wherein said processing means generate an analog lamp signal to maintain such lamp in a warm condition without generating substantial light at times other than when images are being displayed and other than when the microfiche is being moved.
Claim 13
Dependent Claim
25 words
A system as in claim 11, wherein said analog lamp signals are pulse signals, the frequency of such pulses determining the brightness of the lamp.
