Patent number: 4749289Abstract: In a printer for printing an attributed character by printing a character part and an attribute part separately, the invented printer or typewriter is so constructed that only an attribute part, e.g., an underline part or a bold face part, is printed in case a printed character is detected to already have the attribute, i.e., is underlined, or bold face, thereby preventing a character part of the printed character from being double printed. This results in improved quality in printed characters and in complete clear character erasures. The printer is also effective for overprinting attribute parts to over a desired range of printed characters.Type: GrantFiled: June 9, 1987Date of Patent: June 7, 1988Assignee: Brother Kogyo Kabushiki KaishaInventors: Yoshio Sugiura, Kiyoshi Yamakawa

Patent number: 4729678Abstract: A method and apparatus for printing characters in bold form in a typing system. As disclosed, characters entered through an input device such as a keyboard are printed on paper, placed in a display and stored in memory substantially as they are entered. After a group of characters, such as a line of characters, have been entered and printed, those characters which are to be printed in bold form are identified from the information stored in the memory. The thus-identified characters are then printed a second time at a position slightly offset from that of the first printing of each of the characters.Type: GrantFiled: March 31, 1987Date of Patent: March 8, 1988Assignee: International Business Machines CorporationInventors: Douglas E. Hays, James F. Lederer

Patent number: 4624588Abstract: A check encoder (11) for printing of full field MICR (Magnetic Ink Character Recognition) codes on checks, includes a check guide (19) and means for sensing the position of the check (25,27) in the check guide (19). A pair of fixed roller assemblies (29,31), coact with a pair of movable roller assemblies (33,35) to grip the check and move the check under the action of a stepper motor (44) to an initial known position. A hammer (87), mounted in a hammer mount (83) and activated by an electrical solenoid (91) impacts the check against successive selected characters on a font wheel (61) to print the desired MICR code. A computer program, controls the operation of the check positioning, check encoding and check moving operations. When the desired MICR code has been printed on the check, the check is moved out of the encoder (11) by means of the fixed and movable roller assemblies (29,31,33 and 35).Type: GrantFiled: November 8, 1983Date of Patent: November 25, 1986Assignee: Maverick Microsystems, Inc.Inventor: Ken L.

Patent number: 4320980Abstract: Characters are typed in reverse, i.e. light characters on a dark background by first typing all over the field of the character using an ink ribbon, back spacing and typing the character using a correcting ribbon. The first typing may be effected with a solid character covering the whole field in one or a few operations but, in the preferred embodiment is effected by repeatedly typing a vertical bar with tiny line feed increments, say 1/120". The first typing may take place on depression of a special key, which also effects the back spacing and the correcting ribbon; the character key is then struck. Preferably the whole sequence takes place automatically upon depression of the character key while a mode selector is in REVERSE mode.Type: GrantFiled: February 6, 1980Date of Patent: March 23, 1982Assignee: Ing.
