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.

Drawing device and method of drawing

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.

In an acoustic ink jet printer, a configuration is such that an ink unitand a piezoelectric body unitare 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. 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.

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.
