Abstract: A drawing device includes a pen that applies a liquid material to a drawing surface and a cap that covers a tip side of the pen and is arranged at a standby position of the pen. The cap includes: an inner cap that has an opening and covers the tip side of the pen when a periphery of the opening is brought into contact with the outer peripheral surface of the tip side of the pen; an outer cap that has an opening, is arranged outside of the inner cap, and covers the tip side of the pen that is covered by the inner cap when the pen is locked into the outer cap; and an elastic member that is arranged between the outer cap and the inner cap and energizes the inner cap towards an opening side of the outer cap. The pen and the outer cap each have an interlockable locking mechanism.

Abstract: A drawing apparatus includes a drawing head, a movement mechanism, and a control unit. The drawing head holds at least one modification member having a first tip at its one end and operates in such a way as to allow the first tip of the modification member to touch ink which is undried or uncured and applied to a drawing target. The movement mechanism moves the drawing head. The control unit controls the drawing head and the movement mechanism. The control unit controls a modification operation in which the movement mechanism moves the modification member through the drawing head while the first tip is touching the ink on the drawing target so that a part of a pattern formed with the ink on the drawing target is modified.

Abstract: A color correction print apparatus includes a print head and a print data correction unit. The print head prints an image on a printing surface. The print data correction unit corrects, on the basis of a first density value of a constituent color included in the image and a second density value of the constituent color of the printing surface, the first density value.

Abstract: In an acoustic ink jet printer, a configuration is such that an ink unit 5b and a piezoelectric body unit 5a are separated, and a printing is carried out by the ink unit moving on the piezoelectric body unit. Herein, a configuration is such that a plurality of ink cartridges are disposed on a recording head 5. Also, at this time, a configuration is such that only necessary ink cartridges are disposed on the recording head. An acoustic ink jet printer is obtained with which a replacement of a head unit is unnecessary even in the event of a clogging or the like occurring in a nozzle, and with which, the structure of the ink cartridges being simplified, and furthermore, a simplification of the apparatus being achieved even when colorizing, a reduction in cost is possible.

Abstract: Ink for use in an ink-jet color recording apparatus and a plurality of kinds of small microcapsules dispersed in the solvent, each small microcapsule having an outer shell destroyable with ultrasonic waves of a predetermined resonant frequency, each small microcapsule containing a color former within its outer shell with the outer surface of the outer shell covered with a developer. The plurality of kinds of small microcapsules are destroyed selectively with the corresponding predetermined stimuli to thereby produce magenta, cyan, yellow or black. The ink is colorless before producing the color. The ink-jet color recording apparatus irradiates the plurality of small microcapsules with ultrasonic waves of a selected frequency corresponding to a desired color to thereby change the color of the ink on a path through which the ink is fed from a color ink feeding device to an ink cartridge.

Abstract: A color image forming method and apparatus using larger microcapsules each of which contains a plurality of kinds of smaller microcapsules scattered within the larger microcapsule, reacting substances that are mixed with each other to perform a coloring reaction being scattered inside and outside the smaller microcapsule. A protective wall of each smaller microcapsule is broken with a corresponding predetermined ultrasonic stimulus depending upon color component information to thereby cause the reacting substances to diffuse with each other to perform a coloring reaction and hence image printing. The conditions for breaking the protective walls of the respective smaller microcapsules that contain a color former component vary from smaller microcapsule to smaller microcapsule, or are determined depending upon the outer shapes, materials and thickness of the protective walls of the smaller microcapsules.

Abstract: An electrostatic recording apparatus includes a developing agent carrier member provided to extend along a predetermined path. A developing agent convey unit conveys a developing agent along the surface of the developing agent carrier member. The developing agent carrier member has a step in a developing agent convey direction of its surface. A plurality of recording electrodes are aligned on an upper surface of the step of the developing agent carrier member and spaced apart from each other with gaps therebetween in a direction perpendicular to the developing agent convey direction, and project uniformly from the step. An opposite electrode is disposed to oppose the plurality of recording electrodes. A leaf spring member supports at least portions of the plurality of recording electrodes projecting from the step and can swing the projecting recording electrodes in directions to approach to and to separate from the opposite electrode.
