  • Patent number: 4725158
    Abstract: A printing apparatus comprises an input device for entering a plurality of sets of data, each set including title information and character information associated with the title information. A memory stores a plurality of the sets of data entered by the input device and a printer is responsive to sets of data read from the memory to print any one of those sets of data either fully or partially. A selection device selectively causes the printer to print any one of the sets of data either fully or partially. The printing apparatus may also include a selector for selecting one of a first printing mode and a second printing mode. In the first printing mode, when selected, the printer is caused to print both the title information and the character information which may comprise text information. In the second mode, the text information is printed without the title information.

  • 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: 4714364
    Abstract: A paper setting mechanism of a printer for setting a sheet of paper in position around a platen roller for printing desired information includes a paper bail assembly having at least one bail roller, which is pivotally supported and normally biased so as to cause the bail roller to be pressed against the platen roller. The paper bail assembly may be set in a set position in which the bail roller is pressed against the platen roller and it may also be set in a retracted position in which the bail roller is separated away from the platen roller. After insertion of paper, the platen roller is driven to rotate first in the normal direction over a first predetermined amount and then in the reversed direction over a second predetermined amount, which is smaller than the first predetermined amount, whereby the reversed rotation of the platen roller is utilized to cause the paper bail assembly to return to its set position automatically.

  • Patent number: 4712934
    Abstract: A typewriter carriage escapement mechanism comprises a rack (10) movable with the typewriter carriage (2) and having two sets of teeth (16 and 18) projecting in opposite directions. An escapement dog (30) has two separate teeth or sets of teeth (44 and 54) arranged to engage the two sets of rack teeth (16 and 18) alternately as the dog (30) moves at right angles to the rack (10), on operation of the keys (90) or space bar (92) of the typewriter. One of the sets of teeth (54) is mounted on a pawl (50) movable relative to the other tooth (44) or set of teeth, to enable both sets of teeth to be disengaged from the rack (10) to release the carriage (2). The pawl (50) is movable against a return spring (70) by means of an actuating rod (80) engaging a lug (62) on the pawl (50). The mechanism of the invention enables a single escapement member (30) to effect both the stepwise movement of the carriage (2) and also the carriage release.

  • Patent number: 4712933
    Abstract: When a ribbon cassette containing a print ribbon and having a looped portion exposed to the outside is mounted on a printer frame, a ribbon guide member movable along a print line of a platen, while in its initial position, is located within a region surrounded by the looped ribbon portion. The ribbon guide member is moved as a carriage mounted with a print head travels. While in engagement with the looped ribbon portion, the ribbon guide member moves to a position beyond one end of a printing range, where it is releasably latched. Thus, the ribbon is automatically stretched to cover the whole printing range.

  • Patent number: 4707159
    Abstract: A printer for performing recording successively while a recording head moves backwards and forwards in a predetermined direction with respect to a recording medium such as paper. A paper hold roller for pressing the recording medium against a platen in the vicinity of a recording area opposite to a print head is detachable from the platen in relation to the movement of a carriage for carrying the recording head. The presence and absence of paper is detected to control the paper feed. An ink ribbon is provided which has color zones and an ink absorption zone in the direction of the ribbon width for multi-color printing by shifting the ribbon in the width direction by means of the carriage movement so that a selected color zone faces the recording head. The printer further includes a ribbon cassette, means for controlling paper insertion and feeding and means for cleaning the recording head. Also included are a paper bail control, color zone selector and paper detector.

  • Patent number: 4707155
    Abstract: An apparatus for supplying a newly re-coated continuous ribbon to a moving printhead carrier in a printer. The present invention is particularly adaptable for use in thermal printers having multicolored ribbons. The apparatus comprises a cartridge housing which is mounted on the printer frame, and which contains the ribbons. The newly re-coated ribbons exit the cartridge housing, become coupled to the moving printhead carrier, and then reenter the cartridge housing as used ribbon. The used ribbon passes a re-coating station where it is re-inked through contact with a donor ribbon and heated pressure rollers to become newly re-coated ribbon. A lift arm on the printhead carrier selects the desired colored ribbon which has been newly re-coated for printing.

  • Patent number: 4702632
    Abstract: A printing apparatus is disclosed which comprises a platen roller for feeding a cut paper sheet set on a hopper, a paper bail bar having paper bail rollers used in conjunction with the platen roller to secure the cut paper sheet against the platen roller, and a paper loading mechanism for loading the cut paper sheet by causing rotation of the platen roller at a predetermined angle. The paper loading mechanism includes a paper bail switch for checking whether the paper bail roller is in contact with the platen roller. When it is detected by the paper bail switch that the paper bail roller is released from the platen roller, the platen roller is rotated in the normal direction at a first predetermined angle. When, it is detected by the paper bail switch that the paper bail rollers are in contact with the platen roller, the platen roller is rotated in the reverse direction at a second predetermined angle.

  • Patent number: 4699533
    Abstract: An improved resistive ribbon for thermal transfer priting in which a coating is located on the resistive layer in order to reduce contact resistance between the ribbon and printhead, thereby reducing undesirable heating at the contact region between the ribbon and printhead. The coating is comprised of compositions selected from the group consisting of Cr-N, Sn-SnO, ITO, AlN and Al-Al.sub.2 O.sub.3, where the resistivity of the coating is significantly less than the resistivity of the resistive layer of the ribbon. Further, the sheet resistivity of the coating is greater than the sheet resistivity of the resistive layer. The rest of the resistive ribbon can be comprised of any combination of the usually employed layers, such as a current return layer, a release layer for facilitating the transfer of ink from the ribbon to a carrier, and the ink layer itself.
