Patent number: 5496119Abstract: After initialization (S1), the cassette signal is retrieved (S2). Then the tape width of the tape in the tape cassette mounted in the tape printer is determined by tape TB1 (S4). The width of the image display zone is calculated using the tape width and using the table TB5 (S7). The data of standard format information is stored in the start address of the text memory (S8). A text input screen is displayed set with the image display zone corresponding to the tape width calculated in S2 for the display. A cursor is also displayed having the size of the display character size, which was determined based on the print character size, which has been calculated using the tape width, the number of lines "1," and the table TB3. Accordingly, it is possible to provide a grasp of the relation between tape width and the situation at which characters will be printed.Type: GrantFiled: December 28, 1994Date of Patent: March 5, 1996Assignee: Brother Kogyo Kabushiki KaishaInventors: Yasushi Kawakami, Kazuaki Koie, Sachiyo Nakahigashi, Kengo Omura, Shiro Yamada, Yasuyo Ooshio, Kazuko Ishida, Hideo Ueno, Minako Ishida
