A reading rack for reading in a lying position, comprises a lamp stand, detachable book shelf, pen rack, folding legs, flexible metal arm, adjustable rod, folding arms, and clamps. The illuminating lamp is fixed on the lamp stand through a flexible metal arm, and the direction of the illuminating lamp can be adjusted to fit a reader's position. The detachable book shelf is attached on the rear of lamp stand by a sleeve ring. The flexible metal arm is fixed on a link rod, and can be freely bent; ...

A batch reading system for automatically reading documents such as tags or tickets having data marked thereon in the form of human readable characters which are also automatically readable by suitable apparatus, the system being capable of feeding documents which are curled, wrinkled, bent, and otherwise deformed or mutilated. The documents are fed from an input hopper by first feed means, which may be a vacuum belt, from which they are fed to a second vacuum belt on whose underside the tags are...

A dobby with a mechanical reading device for a control card having perforated and nonperforated portions therein according to a pattern. The reading needle of the reading device of the pattern card has yielding elements for the purpose of reducing the impact force of the reading needle onto the pattern card.

Apparatus for storing and reading data in association with a card which has a timing track comprising at least three different kinds of optically-readable timing markings arranged in the timing track in a cyclic sequence, and a data track, the apparatus including three optical timing sensors respectively responsive to the three different kinds of timing markings, and a reading direction detector controlled by the timing sensors.

An apparatus with a holder body forming a flat surface with an angular support member to hold a printed publication at a convenient angle. The publication maintains intimate contact with the body being superimposed with a transparent fixably attached retaining plate. The retaining plate being vertically adjustable and removable with hairlines inscribed into the parent material extending horizontally and vertically. An opaque locator body is slideably attached to the retainer plate with an overla...

The method of the present invention, in its broadest aspect, comprises the steps of generating a character mask or template of each of the printed characters to be machine read from the printed document which is to be machine read; providing with the template, in a machine readable format, labels in association with and identifying each of the character masks or templates; interrogating one line at a time of the printed document with the respective ones of the character masks or templates, to id...

For facsimile transmission or the like an optical system scans an original document and produces quantized electrical signals which are stored in a buffer memory. A data compression unit reads out the signals and performs data compression thereon asynchronously with storage of the signals in the buffer memory. The data compression rate decreases in accordance with the proportion of high density areas of the document, and the electrical data signals accumulate in the buffer memory. The scanning s...

A machine for teaching students to read is equipped with a visual display, a manual keyboard for entering alphabet letter responses, correctness and incorrectness indicators of display responses, and conditioning means for initiating particular grammar characteristic sequences to be practiced. The machine also includes a repertoire of words and letter combinations corresponding to word roots encoded in an electronic form and stored in digital memory. A word set is assembled in response to an ins...

Optical reading head, particularly for reading luminescent code bars on documents and the like, which reading head is provided with a source of light for irradiating the bars, with a detector including a hollow optical guide means for collecting the rays emitted by the bars, said guide means being made of a filter material transmitting ultraviolet radiation at least at the end of said guide near the point where the rays are collected.

A portable map-display system for auto, boat and airplane uses and the like includes a plurality of translucent maps and a compact light box proportioned for back-lighting one map at a time. To prevent unshielded glare from the light-box and to assure proper orientation of maps on the light-box a series circuit arrangement turns off the light circuit in the box when a map is not properly in place over the light-box. The series circuit arrangement includes a conductive strip asymmetrically dispos...
