Patent number: 6196653Abstract: An ink jet printer includes a print head having ink nozzles, which is movable in a direction across the feeding path. A supply mechanism is provided at one side of the feeding path, which supplies ink to the print head located in the ink supply station. A maintenance mechanism is provided at the other side of the feeding path, which operates a predetermined operation. The ink jet printer is further provided with a first clutch which transmits the rotation of the actuator to the supply mechanism only when the print head is located in the above-mentioned one side, and a second clutch which transmits the rotation of the actuator to the maintenance mechanism only when the print head is located in the above-mentioned the other side. With this, the supply mechanism and the maintenance mechanism are actuated by a common actuator.Type: GrantFiled: July 1, 1998Date of Patent: March 6, 2001Assignee: Brother Kogyo Kabushiki KaishaInventors: Hiroshi Igarashi, Hiroo Ogawa, Makoto Ishii, Hiroshi Tokuda, Shinji Kimura, Takashi Nakata

Patent number: 6183060Abstract: An ink-jet recording apparatus includes a head for ejecting ink and a carriage for conveying the head. When the cartridge has moved to a maintenance area and rotates a lever, the rotational force is transformed into a force for causing a pressing plate supporting a strip to move against the nozzle, by means of bevel gears, a pressing piece and a pivot arm. The strip comes in contact with the nozzle surface to wipe ink. The recording apparatus has a pump for applying a pressure to the interior of the head for purging the head and a conveyer for conveying the strip to refresh the part of the strip opposing the head. The pump and conveyer can be driven by a common motor which is also used for conveying the recording medium. The driving source used for the recording apparatus is shared thus making it possible to achieve a simplified configuration of the recording apparatus.Type: GrantFiled: July 17, 1998Date of Patent: February 6, 2001Assignee: Brother Kogyo Kabushiki KaishaInventor: Hiroshi Tokuda

Patent number: 6161917Abstract: An ink jet recorder includes a recording head, a carriage for reciprocating the head, a sheet conveying roller, a motor for driving the roller, a maintenance mechanism and an ink supply mechanism. The driving force from the motor can be transmitted through a first clutch to the maintenance mechanism, and through a second clutch to the ink supply mechanism. One of the clutches is connected to a turn lever, and the other is connected to a shift lever. Each of the clutches can be switched mechanically by the carriage engaging with the associated lever. The single motive power source can drive a plurality of mechanisms. There is no need of a special switch for changing over the source.Type: GrantFiled: July 17, 1998Date of Patent: December 19, 2000Assignee: Brother Kogyo Kabushiki KaishaInventors: Hiroshi Igarashi, Hiroo Ogawa, Makoto Ishii, Hiroshi Tokuda, Shinji Kimura, Takashi Nakata

Patent number: 6045211Abstract: A detector detects the presence of a roll of a strip-like material within a cassette in a maintenance unit used in an ink-jet printer. The detector has a first movable part to rotate and press a switch when the cassette is not positioned at the predetermined mounting position, and a second movable part to rotate and press the switch when less than a predetermined amount of the strip resides in the cassette. The detector, based on the pressed state of the switch, detects whether the maintenance operation can be started. The detector has a pair of pivot arms which each have a similar shaped portion to the other so as to fold into each other and which project into the interior of the cassette when no roll resides in the cassette. When there is a roll inside the cassette, one arm comes in contact with the roll so that the arms retract from the cassette by folding the similar shaped portions into each other.Type: GrantFiled: July 17, 1998Date of Patent: April 4, 2000Assignee: Brother Kogyo Kabushiki KaishaInventor: Hiroshi Tokuda

Patent number: 5568237Abstract: An elongated toner box extending in a horizontal direction has a cylindrical portion where a toner discharge port is formed. A wrapping member serving as a shutter is rotatably disposed over the cylindrical portion for selectively shutting off the toner discharge port. The wrapping member has a circular shape concentrical with the cylindrical portion. A developing case is provided to which the toner box is detachably installable. The developing case has a wall confronting the toner box, and a toner inlet port is formed at the wall. A toner inlet shutter is slidably movably supported to the partition wall. When the wrapping member opens and closes the toner discharge port, the wrapping member is positioned close to the outer surface of the toner box and does not largely protrude from the toner box. Further, the discharge port shutter and the inlet port shutter are movable in interlocking relation with each other.Type: GrantFiled: February 6, 1996Date of Patent: October 22, 1996Assignee: Brother Kogyo Kabushiki KaishaInventors: Kazuhito Ishida, Hiroshi Tokuda, Shinji Kimura

Patent number: 5201507Abstract: In a cassette type sheet supplying device, two or more adjoining spaces for installing standard cassettes therein are joined into a continuous space to enable a large cassette to be installed in the space in lieu of two stantard cassettes. When no cassette is installed or a standard cassette is installed, a paper feeding unit is pulled to the paper feeding position by a spring, and a claw portion of a lock material engages lock holes formed on paper feeding unit side frames so that the paper feeding unit is held to the paper feeding position. When the large cassette is inserted in the cassette installation space, a lock release projection formed on the large cassette comes in contact with a projection of the lock material and extends it to the outside. At this time, the claw portion comes off from the lock hole. When the large cassette is further inserted, the paper feeding unit is pushed through a cushion material.Type: GrantFiled: January 30, 1992Date of Patent: April 13, 1993Assignee: Brother Kogyo Kabushiki KaishaInventor: Hiroshi Tokuda
