摘要： An objective lens holder of the present invention includes: (i) a cavity, having an entrance and an exit, which guides, to an objective lens, an incident light beam entering the entrance, the exit being provided on a side of the cavity where the objective lens is housed; and (ii) an aperture having an opening for limiting, to an effective diameter of the objective lens, a beam diameter of the incident light beam passing through the cavity. The cavity is surrounded with internal wall surfaces facing each other so that space between the internal wall surfaces gradually increases from the opening of the aperture toward the entrance or the exit. This makes it possible to provide a highly rigid objective lens holder that allows high speed read/write operations.

摘要： In a lens holding system of the present invention, at least two lens protection sections protruding from a surface of a lens holding section are provided, which surface faces the optical recording medium, the lens protection sections sandwiching an objective lens therebetween. A distance between each of the lens protection sections and the optical recording medium is smaller than a distance between the objective lens and the optical recording medium. Accordingly, according to the structure mentioned above, because each of plural lens protection sections is independently provided, spaces between (i) adjacent lens protection sections and (ii) each of the lens protection sections and the lens holding section are easily formed. This makes it possible to easily perform attachment/detachment of the objective lens to/from the lens holding section. Further, a region for releasing heat is easily formed by the space provided between adjacent lens protection sections mentioned above. Therefore, it becomes possible to prevent temperature rise, caused by generation of heat in driving sections, of the objective lens and a region surrounding the objective lens.

摘要： An ink jet printing apparatus and an ink jet printing method according to the present invention suppress a variation in the density of ink in a supply channel and a print head without the need for useless recovery operations, thus always providing very reliable high-grade images. The ink jet printing apparatus carries out printing using a print head for ejecting ink. The apparatus includes a scanning unit for causing the print head to scan across a printing medium, a measuring unit for measuring a time from an end of a preceding printing operation until a start of a current printing operation, and a determining unit for determining whether or not a result of measurement executed by the measuring unit exceeds a predetermined value. The scanning unit causes the print head to carry out at least one idle scan before the start of a printing operation depending on a result of determination made by the determining unit.
