Patent number: 7306387Abstract: A tape printer includes a holder support member at one side end in a roll sheet holder storage part in a direction substantially perpendicular to a feeding direction. In the holder support member, a mounting piece which is substantially rectangular in section and formed protruding outward on a positioning holding member of a roll sheet holder is fitted. The tape printer further includes a flat portion formed substantially horizontally between a rear edge of an insertion opening through which a roll sheet is inserted into the tape printer. On the flat portion, a front portion of a guide member is placed. At a rear edge of the flat portion in the feeding direction, at plural positions corresponding to various kinds of the roll sheets having different widths, there are formed four second positioning grooves in which part of the guide member is fitted.Type: GrantFiled: August 2, 2006Date of Patent: December 11, 2007Assignee: Brother Kogyo Kabushiki KaishaInventors: Kiyoshi Sugimoro, Keiji Seo, Akira Sago, Atsushi Kasugai

Patent number: 7281873Abstract: Print sheets 7 stacked up are inserted into a package member 8 so that the sheets 7 in this state can be set in a printer together with the package member 8. The package member 8 is provided with an identification mark 31 while the printer is equipped with a reflective sensor so that the identification mark 31 will be placed in a reading area of the reflective sensor only when the sheet package 9 is loaded in the printer in a correct direction.Type: GrantFiled: March 17, 2003Date of Patent: October 16, 2007Assignee: Brother Kogyo Kabushiki KaishaInventors: Minoru Yamamoto, Keiji Seo

Patent number: 7283147Abstract: A roll sheet is unwound and fed with its side edge being positioned in a reference point of the thermal head, and then subjected to printing by the thermal head. Coil springs are placed at positions respectively dividing substantially equally a length from a center to each end of the thermal head. A distribution of loads on the thermal head by each coil spring is determined so that a load exerted on the thermal head on the reference point side is larger than a load exerted on the thermal head on the opposite side. A position of a resultant force of the coil springs acts on the thermal head at a position displaced by a distance obtained by multiplying an entire length of the thermal head by a coefficient, from a center of the thermal head in the longitudinal direction toward the reference point.Type: GrantFiled: June 10, 2005Date of Patent: October 16, 2007Assignee: Brother Kogyo Kabushiki KaishaInventors: Akira Sago, Keiji Seo, Teruo Imamaki, Takashi Higashi

Publication number: 20070212150Abstract: A tape printer includes a roll sheet holder storage part of which a bottom is formed with a positioning recess which is rectangular in plan view and long sideways and has a predetermined depth. A discrimination recess rectangular in plan view is provided between the positioning recess and an inner base end of a holder support member). The discrimination recess fittingly receives a sheet discrimination part extending in a predetermined length from a lower end of the positioning holding member inward at substantially right angle thereto. The sheet discrimination part is formed with sensor holes arranged in an L-shaped pattern. In the discrimination recess, there are provided sheet discrimination sensors arranged in an L-shaped pattern.Type: ApplicationFiled: May 3, 2007Publication date: September 13, 2007Applicant: Brother Kogyo Kabushiki KaishaInventors: Kiyoshi Sugimoto, Akira Sago, Keiji Seo, Atsushi Kasugai

Patent number: 7198420Abstract: A printer 1 includes a sheet storage unit 6 in which a stack of sheets can be set, a pickup roller 12 which contacts one side of the stack of sheets set in the sheet storage unit 6, and a lid 10 which covers the other side of the stack of sheets. In this structure, each sheet 7 is conveyed toward a print mechanism unit 14 by the revolution of the pickup roller 12. The printer 1 is provided with first ribs 10a and a second rib 3a which forcibly curl the sheets 7 set in the sheet storage unit 6 in the sheet width direction.Type: GrantFiled: February 26, 2003Date of Patent: April 3, 2007Assignee: Brother Kogyo Kabushiki KaishaInventors: Minoru Yamamoto, Takashi Okumura, Hiroshi Taira, Keiji Seo
