  • Patent number: 7214897
    Abstract: An illuminated keyboard with illuminated figures being formed on the top surface of the keyboard including: a top cover, a bottom cover, a plurality of keys and an electroluminescent board. The top cover accommodates the keys and is combined with the bottom cover. The electroluminescent board is installed between the top cover and the bottom cover. The electroluminescent board includes at least one figured pattern to be displayed on a top surface of the keyboard on the top cover when the electroluminescent board is electrified to give light.

  • Patent number: 5791792
    Abstract: Ideographic typewriter and method in which a set of characters are printed on a keyboard panel in optically readable form and scanned to provide a bit map of a character which is to be printed. A printer is actuated in accordance with the bit map to form an image of the selected character on an output medium. Characters beyond those included in the set printed on the keyboard panel can be written on a calligraphy pad near the keyboard and scanned to provide bit maps for use in the printing of those characters. Information associated with the characters is prerecorded in tracks on a magnetic medium positioned beneath the keyboard panel and transduced in a manner which substantially eliminates crosstalk between the tracks.

  • Patent number: 4813798
    Abstract: Described is a lighting arrangement for typewriters or printers, which is arranged on a light shade member (4, 14) above the printing or typing mechanism well. For that purpose a fluorescent tube (6) may be disposed in a separate tube (7) at the front edge of the light shade member (4) or it may be integrated into a thickened portion. A light exit window (8) is so disposed as to provide for dazzle-free lighting of the material being typed.

  • Patent number: 4722621
    Abstract: A keyboard assembly for selecting characters to be recorded includes a substrate carrying an array of characters arranged on one face thereof. A character selection device moves between advanced and retracted positions along each of two axes of the array and, by means of an optical viewfinder, registers a given character with respect to the position of the selecting device. Registration openings distributed along each of the two axes cooperate with an associated detent carried by the selecting device so as to retain the selecting device in a fixed position relative to the locus of the character which has been selected. Movement of the character selection device to the locus of a given character serves to control the recording of the character selected.

  • Patent number: 4626117
    Abstract: A typewriter comprises a carriage (1) sliding parallel to a platen (3). The typing device (2) operates in a printing zone which is displaced along this platen (3).The casing (7) of the machine is open above the platen (3) and has a transparent anti-noise hood (10) covering its opening (8).In order to facilitate the reading of the last line of type across the hood (10) which absorbs a part of the light, the typewriter is provided with means for illuminating the platen (3). These illumination means are constituted by electric bulbs (17) either carried by a transparent slide (14) housed in a U-shaped throat (12) or lie in the direction of the platen (3).

  • Patent number: 4447148
    Abstract: An Edge Printing Device is utilized adjacent to the exposure station of a document reproducing apparatus having an auxiliary document handling apparatus mounted over the exposure station. The documents, moving over the exposure station drive a friction roller which in turn rotates an indicia roller so that supplemental information thereon is copied simultaneously with the image on the moving document. The supplemental information is produced on an edge portion of the copy sheet, in an area beyond the lateral dimensions on the copy sheet.

  • Patent number: 4428695
    Abstract: A cartridge which contains two spools. The supply spool has wound about it a printing ribbon and the take-up spool being used for wrapping the used ribbon. The cartridge has a ribbon exit at one location and a ribbon entry at a remote location to define a path for the ribbon to pass therealong. Two drive gears are engaged with each other and a pressure roller. The drive gears are located and their lower portions are configured to engage the respective drive shafts of various printers. When the first drive gear is driven by a printer, the second gear, which includes the drive wheel, rotates in the opposite direction of the drive shaft of the printer. When the second gear is driven, the integral drive wheel rotates in the same direction as the drive shaft of the printer. The pressure roller is provided with internal flexible spokes, or springs, and provides a self-adjusting bias against the drive wheel to drive the ribbon and provides an extremely efficient pinching action.

  • Patent number: 4385461
    Abstract: This sequentially highlighting copy holder employs fields of light as the frame of reference for an operator of a keyboard machine in keeping the place in the text of a document page. The page is affixed upon the copy holder for processing and is illuminated, portion by portion, as the place in the text advances. In one place keeping function the perceived effect of this highlighting delivered in sequence is that of a slender field of light slowly descending the document page. In another, the field of light disappears as a second field appears lower on the page, overlapping the position of the first field of light and disappearing in turn as a third field appears, overlapping the position of the second, so that as the place in the text moves downward the field of light moves with it in salient changes of position, holding to the moving place of attention in the text. In yet another function, ongoing input entered into the keyboard machine sets the downward pace of the field of light.
