An ink-jet recording apparatus includes a positioning device for postioning a recording head on a carriage and an electrical connecting device for establishing electrical connection between the recording head and a main body portion. The positioning device and the electrical connecting device are provided on the carriage independently of each other. Therefore, the recording head and an ink tank can be certainly and simply installed on the recording apparatus. Also, an information processing system employs such recording apparatus to output input information, such as characters, image or so forth on a recording medium.

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.

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 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.

The present invention provides a recording apparatus which can determine a position of a carriage on which a recording head is mounted with high accuracy without enhancing positional accuracy of a carriage position detecting system. In this recording apparatus, a rod-like member is moved upwardly to be engaged by a recessed portion formed in the carriage. A deviation amount of the carriage generated by such engagement is detected by a linear encoder and is used as a correction value when the carriage is moved next time.

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.

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.
摘要:
A recording apparatus performs recording on a recording medium by using a coloring material-containing ink accommodated in a first accommodating portion and processing liquid contained in a second accommodating portion to make insoluble or coagulate the coloring material in the ink. This recording apparatus includes a means to hold a first ink jet head to eject the ink and a second ink jet head to eject the processing liquid in line and in an opposing relationship with the recording surface of the recording medium, and a control means to control the ejecting of the processing liquid from the second ink jet head in connection with the ejecting of the ink from the first ink jet head.
摘要:
In a recording apparatus for recording on a recording medium by using a plurality of recording heads arranged at a predetermined interval in a scan direction, the recording heads are caused to scan corresponding divided recording areas. When the recording heads are caused to scan the corresponding divided recording areas, at least one of the recording heads is caused to record in a plurality of different recording areas. Positions of a recording medium are defined at a plurality of reference positions provided for the recording areas in which the recording is made.
