A sloped surface is provided inside an ink tank of an exchangeable ink jet head cartridge arranged in a scan-type ink jet apparatus. An acceleration of the ink jet head cartridge scanned for recording and an inertia of ink are utilized to allow the ink to climb the slope, whereby the ink can be favorably supplied to a recording head.

An ink-jet recording method employs a light-tonable recording liquid capable of being toned by light radiation, the liquid preferably containing a recording agent having an absorption peak within a certain wavelength range, an ammonium salt of an organic boron, and a liquid medium. The hue or the density of a desired portion of the light-tonable recording liquid on a recording member is changed by radiating toning light onto that portion. The recording member may have colored portions of an image previously recorded with a light-tonable recording liquid or colored portions just formed in the current recording. Toning light is radiated onto a desired position of the recording region of the member while varying the intensity and/or the period of light radiation in accordance with an information signal. Thus, toning may provide various half-tones or may render the toned portion of the recording liquid colorless, thereby erasing the relevant colored portions. Selective erasure may be followed by re-recording on the same position of the recording region, thereby effecting correction. All-surface erasure allows the recording member to be reused.

A roller comprises a rotary shaft, an outer peripheral wall member for defining an outer peripheral surface to be contacted with a sheet, and a support member for supporting the outer peripheral wall member so that the outer peripheral wall member surrounds the rotary shaft. The support member defines a space between the rotary shaft and the outer peripheral wall member and supports the outer peripheral wall member with maintaining a condition that the outer peripheral wall member is deformed to swell radially outwardly.

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.
摘要:
A liquid storage apparatus which comprises a pouring opening at the top of a vessel and a passage which is partially defined by a shield wall for preventing straight access of a liquid to the pouring opening. The structure defining the passage facilitates downward backflow of the liquid and is provided below and near the pouring opening.
摘要:
A recording device for reproducing an image from an original onto a recording medium as a visible image. The device includes a mounting table for supporting the original and a feeding device for feeding the original onto the mounting table. A detector device detects the arrival of the original at a predetermined position on the mounting table, and recording apparatus then records the information from the original onto a recording sheet. Recording is initiated by an instruction device in response to an output from the detector. A conveyor for the recording sheet then carries the recording sheet along a discharge path wherein a folding device is selectably operable to move the sheet against a stopping device to impart a fold to the sheet, whereupon the sheet is discharged to a tray in a folded or unfolded state.

In a serial recording apparatus wherein a recording head is carried on a carriage movable in the direction of a print column and the recording head is driven on the basis of printing data while scanning by the recording head, to thereby form a dot image on a sheet, piezoelectric elements are joined to a vibration plate provided on the underside of the carriage and the vibration plate is slidably urged against the surface of a fixed member by a resilient force to thereby constitute a travelling wave type ultrasonic motor. A travelling wave is generated in the vibration plate by the piezoelectric elements being driven to thereby control the movement of the carriage.

There is disclosed an image formation apparatus having a convey system for a recording medium in a continuous paper form such as fan fold paper, a recording means for forming images along the entire width of the recording medium, and the like, of which the operability is improved.
摘要:
An image forming apparatus having an oscillating recording head includes a recording device for recording the image onto a recording medium. Oscillating apparatuses provided for oscillatably supporting the recording head in accordance with a reference surface associated with a recording surface of the recording medium. Oscillation auxiliary apparatus supports the recording head to smoothly allow oscillation thereof.
摘要:
A data recorder in which a recording is moved by stepping motor whose rotor rotation angle is detected, the stepping motor having a current switching circuit which controls the application of excitation current to the drive coils of the motor in accordance with the detected rotation angle. A control circuit counts the detected result of the rotor rotation angle, detects the position of the head and generates start and stop control signals of the head, thereby starting and stopping switch-over control of the current switching circuit being effected.
