| 106 | Electronic printer with interleaved storage of print wheel position, hammer intensity, and carriage position data in read only memory | US748985 | 1985-06-26 | US4687356A | 1987-08-18 | Hirotoshi Matsui; Takeo Tsumura; Eiichi Sakanaka |
| An impact-type electronic printer uses a rotary printing wheel and a ROM to store printing-type position data for dealing with respective printing types borne by the rotary printing wheel, hammer pressure data, and the spacing data respectively matching the designated printing types together with printing-type position data. The main CPU then draws out the printing-type position data, hammer pressure data, and the spacing data in response to the input data to allow the printer to execute the printing operation using the designated printing types in accordance with these data drawn out of the ROM, thus realizing distinctly clean printed characters. The unique system embodied by the present invention makes it possible for the controller to easily read important data from the ROM. In other words, since the control system reflecting the present invention allows the ROM to effectively store the printing-type position data, hammer pressure data, and the specifying data in two words, the control system can, for example, securely read the data merely by executing the reading operations twice. | ||||||
| 107 | Dot-matrix printer with font cartridge unit | US770994 | 1985-08-30 | US4660998A | 1987-04-28 | Yukio Tsuneki |
| A dot-matrix printer of the invention uses a font cartridge unit storing in advance character pattern data corresponding to characters other than standard characters. The font cartridge unit comprises a ROM or RAM storing character pattern data in a storage area in units of pages. A CPU sets a given page address in a page address register in the font cartridge unit in the case of dot printing of characters other than standard characters. The CPU reads out desired character pattern data from the storage area of the ROM or RAM corresponding to the preset page address, and stores the readout data in a work memory. A printing mechanism controller controls a printing mechanism including a print head in accordance with the character pattern data stored in the work memory so as to execute dot printng of, e.g., high-density characters other than standard characters. | ||||||
| 108 | Serial printer | US594274 | 1984-03-28 | US4632584A | 1986-12-30 | Raffaele Becchi; Felice Giacone |

| 110 | Impact printing apparatus with interchangeable rotary type wheels | US358556 | 1982-03-16 | US4448555A | 1984-05-15 | Keiji Hasegawa |
| An impact printing apparatus automatically discriminates the kind of a type element mounted on a reciprocating carriage of the printer and interchangeable with another type element. A print control program is selected in conformity to the specific kind of type element while desired printing is carried out according to the selected program. Each of the interchangeable type elements is provided with a mark or marks or coded data to be detected by a sensor which is located in a predetermined position on a stationary part of the printer. The mark or coded data is sensed while the type element is rotated or while the carriage carrying the type element is moved. A single mark in the form of a slit is formed in a rotary hub of the type element, and the sensor for detecting the mark comprises a light emitting element mounted on the carriage and a light receiving element mounted on the stationary part of the printer which corresponds to the light emitting element. A plurality of marks in the form of magnetic pieces are arranged on the rotary hub, tongue or mark bracket of the type element, and the sensor comprises a magnetic sensor mounted on the stationary part of the printer. | ||||||
| 111 | Character set expansion | US208748 | 1980-11-20 | US4359286A | 1982-11-16 | Johnny G. Barnes; Paul D. Waldo |
| A method of, and system for, increasing the number of characters available to be printed with a single print element. If a printer is printing from storage and the character being presented to the printer does not match the print element in use, a determination is made as to whether the character is in fact available on the element. If so, the character is caused to be printed. If not, a determination is made as to whether the presented character can be constructed from characters existing on the print element. If so, construction is caused to occur to avoid a print element change. If, however, the presented character does not exist on the print element and cannot be constructed from characters that do exist on the print element, a requirement for a print element change is signalled. Following a change, printing will continue with the new print element as long as characters are available, or can be constructed from available characters. As such, throughput is improved and required operator attention is diminished. | ||||||
| 112 | Shift mechanism | US165124 | 1979-10-07 | US4299505A | 1981-11-10 | Raymond Clavel |
| The invention concerns a shift mechanism for typewriters having a carriage in which the shift instruction is transmitted by two distinct interlocks of which one is in an active position when the other is in an inactive position. Each interlock is controlled by a primary lever and an auxiliary lever which causes it to work in connection with drive means serving to place it in an active position. A stirrup-shaped pivotal part is provided with two principal elements, one of which comprises the auxiliary lever controlling a first one of the interlocks, and the other element comprising an arm capable of being driven by the second interlock, the latter being normally controlled by the primary lever connected to a key on a keyboard. | ||||||
| 113 | Direct keyboard controlled rack shift device for a single element typewriter | US54760 | 1979-07-05 | US4277188A | 1981-07-07 | Robert F. McDaniel; Mike Prewarski; Leonard D. Ramey |
| A device is disclosed for shifting a bifurcated rack from one position to a second position, thereby engaging alternate sides of a bifurcated rack member with a pinion in a spacially fixed position. The rack shift mechanism is controlled by a direct link to the keyboard of the typewriter which responds to movement of a shift key lever. The mechanism performs a force multiplication and, at the same time, a displacement division function to reduce a relatively large key lever and link displacement to a relatively small rack displacement with a correspondingly higher force factor. The force multiplication linkage translates the rack of the rack/pinion pair to engage the alternate portion of the rack, thereby reversing the rotation of the pinion and allowing the selection from the opposite hemisphere of the type element in response to a selection output. | ||||||
| 114 | Apparatus for producing preliminary character printout of text and instruction codes of word processing apparatus | US913617 | 1978-06-08 | US4220417A | 1980-09-02 | Charles N. Sprott; Leonard S. Yates |
| A method and apparatus associated with word processing equipment for producing a preliminary printout of accessible lines of intermixed text characters and code characters representative of the format of such text. The apparatus includes logic controlled gates for selectively gating text codes, instruction codes, and reference line number codes to a print control coupled to, and controlling the printing by, a printer. Specific networks enable the printing of "font change" instructions and identifications and characteristic identifier symbols indicative of the presence of an instruction code. Audit print codes representing material ones of the instruction codes are substituted for the usual printer functional response to those instruction codes, that is, a code representation of the instruction code is printed instead of the printer executing the instruction. | ||||||
| 115 | Font and column format control system | US884062 | 1978-03-06 | US4205922A | 1980-06-03 | Robert A. Pascoe |
| A system for handling multiple printer font requirements during playout of a plurality of sequentially stored text columns in a side-by-side format. A line from one column is printed on a print line, the carrier is caused to escape, and any corresponding line from a succeeding column is printed on the same line. Printing and escapement continue until all corresponding lines from each column are printed on the same print line prior to causing a printer carrier return. During playout within a column, or from column to column, printer font requirements stored with the text are used to determine subsequent system events. If one of the columns, or a portion thereof, is to be printed in a different type style or language, the system will signal a need for a font change, stop the playout and await an indication that a font change has been made. | ||||||
| 116 | Typewriter attachment | US765279 | 1977-02-03 | US4088217A | 1978-05-09 | Ralph E. Bucknam |
| The device of the present invention is intended to be attached to a ball-element type typewriter to permit rapid switching among a plurality of ball elements. While the invention has utility in any instance where the need arises for switching rapidly and frequently among a number of ball elements, it is particularly useful in systems as described for utilization of a standard typewriter for typing Chinese or Japanese. | ||||||
