摘要:
The present invention provides a sheet convey apparatus having a convey roller contacting with a sheet while rotating to apply a convey force to the sheet, a pinch roller for cooperating with the convey roller to convey the sheet, a support for supporting a center of the pinch roller in its widthwise direction, and a biasing device for biasing the support in such a manner that the support means urges the pinch roller against the convey roller in the widthwise direction of the pinch roller.

A recording apparatus having a carriage which scans along a guide shaft and which is provided with recording heads includes a position detector for detecting the positions of the carriage in the scanning direction; and a fixing device for engaging with the carriage to regulate the carriage in the scanning direction when it is detected by the position detector that the carriage is in a given fixing position and fixing the carriage in the given fixing position. With the structure thus arranged, this recording apparatus is capable of preventing the carriage from being bent or deformed when the ink tanks and recording heads are detachably mounted or the gap adjustment for the recording heads are executed on the carriage, thus enabling the operation and positioning of the carriage to be executed exactly.

Ink jet recording encounters deviations in the position at which a recorded dot is applied due to changes in the distance from the recording head to a recording medium, the carriage movement speed and the ink discharge speed or the like. When bidirectional recording is performed while moving the carriage having the recording head mounted thereon, deviations of the recorded dot may occur in the forward and rearward recording operations. The present invention is arranged in such a manner that values for correcting the deviations occurring in bidirectional recording and corresponding to the changes of the distance from the recording head to a recording medium, the carriage movement speed and the ink discharge speed or the like are previously stored. A drive signal, the timing of which has been corrected with the correction value, is used to operate the apparatus so that high-quality recordings free from deviations occurring in the bidirectional recording operation are obtained. The present invention disclosed a recording apparatus having a plurality of recording heads mounted on a carriage thereof, the recording apparatus being arranged in such a manner that the carriage movement speed is detected to determine the recording timing of the plural recording heads to prevent the deviation of dots formed by the plural recording heads due to the changes in the moving speed caused by changes in the environment of the apparatus to record high quality images.

A recording apparatus for performing recording uses a carriage mounted with a recording head moving along a guide shaft. The recording apparatus includes a magnetic linear encoder consisting of a scale element magnetized and a detection unit for detecting magnetized information magnetized to the scale element. Provided also are clicks formed on any one of the detection unit and the carriage and click engaging portions formed in the other one of the detection unit and the carriage. The clicks engage with the click engaging portions, whereby the detection unit is snap-locked to the carriage. This enables the detection unit of the magnetic linear encoder to be readily attached to the carriage and besides, when attached, prevents disorder of the information magnetized to the scale element. Further, even when a position of the carriage shifts corresponding to sheets having different thicknesses, a sliding load of the carriage does not change. Deformation and abrasion of the scale element of the magnetic linear encoder are restrained as much as possible. Moreover, the abrasion of bearings of a head of the magnetic linear encoder is eliminated.

A printing apparatus has a control unit for controlling the driving of a print head in accordance with a temperature measured by a sensor which is provided on a movable carriage for mounting the print head. The control unit controls a sensor such that the sensor measures the temperature when the carriage is in a position where the heat from motors or the like in the printing apparatus does not affect the sensor on the carriage.

A color ink jet printing apparatus including a single suction mechanism having a capping member designed to cap any one of the printheads of the apparatus and carrying out a suction recovery of that capped printhead. A plurality of additional caps which are not associated with the suction mechanism are provided for capping the printhead. Various printing moving schemes are devised to provide quick and efficient positioning of selected printheads opposing the suction mechanism to speedily service that printhead.

A recording apparatus, which is provided with a carriage supporting a recording head or reciprocating along a platen, includes a magnetized scale of a magnetic linear encoder positioned along a moving direction of the carriage, and a magnetic head of the magnetic linear encoder, mounted on the carriage and adapted for reading the magnetized pattern of the scale. The scale is provided with at least two magnetized lines of mutually different pitches of magnetization, for recording position information relating to the recording operation, and position information relating to other functions.

A recording apparatus effects a recording operation by scanning a recording medium in a predetermined direction with a recording head provided with discharge openings for recording liquid. A cap member is capable of covering a face with discharge openings of said recording head. A transmission member causes said cap member to cover said face with discharge openings in response to a motion setting said recording head to a predetermined position; and engaging members consisting of a protruding part are provided on one of said recording head and a carriage supporting said head. The protruding part engages a receiving part for said protruding part formed on the other of said recording head and said carriage, wherein said protruding part and said receiving part mutually engage at two points when said cap member covers said face with discharge openings.

To provide a roof panel (12) to a vehicle body (1) capable of opening/closing a vehicle cabin space (11), a link mechanism (3) for supporting the roof panel (12) at the vehicle body (1) having a front connecting link (33) rotatably connected to both of the vehicle body (1) and the roof panel (12), and a rear connecting link (34) rotatably connected to both of the vehicle body (1) and the roof panel (12) at rear side of a vehicle relative to front connecting link (33), and link restricting mechanism (500) for restricting the rear connecting link (34) to the vehicle body (1) when the roof panel (12) is in fully closed state over the vehicle cabin space (11).
摘要:
An apparatus uses a liquid ejection head including a first liquid passage communicating with an ejection port, a second liquid passage separated from the first liquid passage by a separation wall, and a movable member formed as a part of the separation wall. In the second liquid passage, a thermal energy generation device is arranged at a position opposing to the movable member. The movable member has a free end portion and a fulcrum. Recovery of the first and second liquid passages is performed by suction and/or pressurization. Upon recovery by discharging the liquid in respective liquid passage having higher flow resistance, the pressurizing force and/or the suction force for the liquid passage having higher resistance is set to be greater that the pressurizing force and/or the suction force for the other liquid passage having lower flow resistance.
