摘要： A high-performance taking lens system suitable for a lens shutter type camera, which is capable of displaying superior optical performance as far as the edges of film image field with minimal deterioration of the performance despite a simple arrangement. The taking lens system has a front lens unit including at least one positive lens (G1) and at least one negative lens (G2) whose image-side surface has a higher curvature than that of the object-side surface thereof, and a rear lens unit disposed behind the front lens unit and including a doublet (G3) which consists of one positive lens and one negative lens and which has a positive refractive power, and a positive lens (G4). The lens surface of the doublet (G3) that is the closest to the image side is concave toward the image side. The intermediate lens surface of the doublet (G3) is convex toward the image side. The negative lens (G2) is preferably a meniscus negative lens having a concave surface directed toward the image side. Focusing from the infinite object point to a near object point is preferably effected by moving the two lens units together as one unit toward the object side while varying the air spacing therebetween.

摘要： A processing device is configured to irradiate a laser beam onto a glass substrate for processing. The processing device has a work table, a laser beam output section, a multi-spot focus section, a rotation drive mechanism, an optical system, and a laser beam scan section. The multi-spot focus section receives a laser beam, and splits and focuses the laser beam inputted therein into a plurality of beam focus spots. The rotation drive mechanism rotates the plurality of beam focus spots about a single center axis that is arranged in a center of the plurality of beam focus spots. The optical system guides the laser beam to the multi-spot focus section. The laser beam scan section moves all the plurality of beam focus spots rotating about the single center axis in a desired direction within a predetermined range of a plane arranged along a surface of the glass substrate.

摘要： A head holder includes a bottom plate of which a bottom surface is fixed to a top surface of a recording head having an ink supply port. A sleeve is fixed to the top surface of the recording head and communicates with the ink supply port. The bottom plate is formed with a recess in which a large diameter tubular part of the sleeve is held. A backup plate encloses a small diameter tubular part of the sleeve and is supported by the bottom plate. An O-ring is inserted around the small diameter tubular part of the sleeve in the backup plate, and an upper end of the sleeve is aligned with an outlet of an ink path in a passage plate laid horizontally in a container, and the passage plate and the bottom plate are fastened using a fixing plate and a bolt. The O-ring is resiliently deformed via the backup plate, so that a gap in a connection between the outlet and the sleeve is sealed.

摘要： A zoom lens system having three lens units, that is, a negative lens unit, a positive lens unit, and a negative lens unit. The idea of floating system is introduced into the rear focusing system to minimize the degree of aberration fluctuation at a short object distance with a simple lens arrangement, thereby stabilizing the optical performance during focusing at a short object distance. The zoom lens system includes a 1-st lens unit (G1) having a negative refractive power, a 2-nd lens unit (G2) having a positive refractive power, and a 3-rd lens unit (G3) having a negative refractive power, and effects zooming from the wide end to the tele end by varying the spacing between each pair of adjacent lens units. With the 2-nd lens unit (G2) defined as a focusing lens unit, focusing is effected by varying the axial air spacing between a lens component (L.sub.F) of the 2-nd lens unit (G2) that is the closest to the image side and the remaining lens component (L.sub.F ').
