Patent number: 7654760Abstract: A tape printer includes a cutter lever that is capable of moving within a prescribed operating range, a tape-cutting mechanism for cutting a printing tape after the printing tape has been printed by a thermal head when the cutter lever moves past a prescribed range, a cutter lever sensor for detecting movement of the cutter lever within the prescribed operating range, and drive circuits for halting the tape-feeding operation and printing operation controlled by a controller when the cutter lever sensor detects an operation by the cutter lever. With this construction, a printing mechanism, which includes a tape-feeding mechanism, is completely halted when a cutter unit is operated, thereby eliminating all tape jams.Type: GrantFiled: December 27, 2005Date of Patent: February 2, 2010Assignee: Brother Kogyo Kabushiki KaishaInventors: Yuji Sakano, Toshihiro Takahashi, Tsuyoshi Minoya

Publication number: 20090218761Abstract: The recording apparatus includes: a recording head having a recording surface; a conveyor unit having three rollers, and a conveyor belt looped around the rollers; and a roller moving mechanism. The mechanism moves at least one of the three rollers so as to allow the conveyor unit to shift between a first state and a second state. In the first state, an image can be formed by the recording head to a recording medium. A conveyor surface faces the recording surface with a predetermined gap therebetween, and the three rollers are in a predetermined relative positional relation so as to apply tension to the conveyor belt. In the second state, a gap larger than the predetermined gap exists between the conveyor surface and the recording surface, and the three rollers are in a relative positional relation different from the predetermined relative positional relation.Type: ApplicationFiled: February 12, 2009Publication date: September 3, 2009Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventor: Yuji Sakano

Publication number: 20090219333Abstract: An inkjet recording apparatus is provided. The inkjet recording apparatus includes an inkjet head having a discharge surface in which discharge ports are formed for discharging ink; a moving mechanism that is configured to move the inkjet head and a recording medium relative to each other; and a capture unit that is configured to capture an extraneous substance, the capture unit disposed upstream of the inkjet head in a moving direction of the recording medium relative to the inkjet head, and disposed adjacent to the inkjet head.Type: ApplicationFiled: February 20, 2009Publication date: September 3, 2009Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventors: Yuji SAKANO, Kiyoshi SUGIMOTO, Hideki YAMAMOTO

Publication number: 20090189967Abstract: An inkjet recording apparatus includes: one or more inkjet heads each having an ejection surface having a plurality of ejection openings formed thereon; and a conveyor mechanism which has a facing region facing the one or more ejection surfaces, and conveys a recording medium placed on the facing region. The inkjet recording apparatus further includes one or more moving mechanisms. Each of the one or more moving mechanisms includes a medium pusher which pushes down a recording medium towards the facing region. The each of the one or more moving mechanisms causes the medium pusher to move between a first position and a second position. The first position is such a position where a distance between the medium pusher and the facing region is further than the distance between the facing region and the ejection surfaces. The second position is such a position where the medium pusher contacts the facing region.Type: ApplicationFiled: January 30, 2009Publication date: July 30, 2009Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventor: Yuji SAKANO

Publication number: 20090167814Abstract: A recording apparatus includes: a conveyor which has one or more holes penetrating from a first surface to a second surface thereof, and which conveys, in a conveyance direction, a recording medium supported on the first surface; and a recording unit which is at such a position as to face the first surface, and records an image on a recording medium while the recording medium is conveyed by the conveyor. The recording apparatus further includes an exhauster capable of causing air exhaust through the one or more holes so that airstream in the one or more holes is directed from the second surface to the first surface; and a controller which controls the exhauster so as to cause air exhaust through at least one medium-facing hole out of the one or more holes, the medium facing hole being a hole facing a recording medium.Type: ApplicationFiled: December 23, 2008Publication date: July 2, 2009Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventors: Kiyoshi Sugimoto, Yuji Sakano

Patent number: 7524120Abstract: A tape printer capable of separating a print head and a platen when the print head and the platen adhere to each other while the tape printer is stored with a tape cassette uninstalled, keeping a holding member at a pressing position. A cassette cover has a pressing cam part which comes into contact with a roller holder to press the roller holder to a pressing position in a closed state of the cassette cover, and a withdrawing cam part which presses a withdrawing cam receiver to return the roller holder to a withdrawing position in the process of shifting from the closed state to an opened state of the cassette cover. Accordingly, the withdrawing cam part forces the withdrawing cam receiver provided in the roller holder, so that the thermal head and the platen roller which have adhered to each other can be surely separated even after the tape printer is stored for a long period with the tape cassette uninstalled, keeping the roller holder at the pressing position.Type: GrantFiled: December 22, 2005Date of Patent: April 28, 2009Assignee: Brother Kogyo Kabushiki KaishaInventors: Tsuyoshi Minoya, Toshihiro Takahashi, Yuji Sakano

Publication number: 20090085971Abstract: An inkjet recording apparatus includes: a conveyance mechanism which conveys a recording medium in the conveyance direction; an inkjet head; a first movement mechanism; a first movement printing controller; a fixed printing controller; and a mode instructor which instructs which one of the first movement printing controller and the fixed printing controller is to be active. The first movement mechanism causes the inkjet head to make a first movement parallel to the conveyance direction. The first movement printing controller controls the conveyance mechanism so that the recording medium stops at a predetermined position. The first movement printing controller also controls the inkjet head and the first movement mechanism so that the inkjet head ejects ink to a stopped recording medium during the first movement. The fixed printing controller controls the conveyance mechanism so that the recording medium passes through an area where the recording medium faces the ejection surface.Type: ApplicationFiled: October 1, 2008Publication date: April 2, 2009Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventor: Yuji Sakano

Publication number: 20080239053Abstract: An image recording apparatus includes a recording head, first and second rollers, an endless conveyor belt wound around the first and second rollers to convey a recording medium from the first to the second roller, a first adsorber giving adsorptivity for the recording medium toward an outer surface of the conveyor belt at least in a region thereof opposed to the recording head, a third roller disposed at a position opposite to the first roller across the second roller, and an endless separation belt wound around the second and third rollers. An outer surface of the endless separation belt has adsorptivity lower than the adsorptivity given by the first adsorber. The endless separation belt receives the recording medium from the conveyor belt and conveys the recording medium from the second roller to the third roller while supporting the recording medium on the surface thereof.Type: ApplicationFiled: March 28, 2008Publication date: October 2, 2008Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventor: Yuji Sakano
