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 ').

摘要： A feeding device for feeding a recording medium having a predetermined printing area on one of its opposite surfaces. The printing area extends in a printing direction. The feeding device includes a pair of feed rollers which holds the medium therebetween in rolling contact with the opposite surfaces of the medium. At least one of the pair of feed rollers is driven so as to rotate about an axis perpendicular to the printing direction, to feed the medium in the printing direction. One of the feed rollers which contacts the above-indicated one surface of the medium has an outer circumferential surface which includes a small-diameter portion whose diameter is smaller than that of the other portions. The small-diameter portion is aligned with the printing area in a direction of width of the medium perpendicular to the printing direction, so that the small-diameter portion is prevented from contacting the printed image. The feed rollers may be replaced by a platen roller of a printer. The platen roller is rotated about an axis perpendicular to the printing direction, and cooperates with a print head of the printer to hold and feed the recording medium such that the platen roller and the print head contact the opposite surfaces of the medium. This arrangement also protects the printed image from an adverse influence by a feeding action of the feeding device.

摘要： An electric data switch, e.g., a rotary switch, that selects data by moving contact portion along tracks of electrodes, in which a contact portion touches two or more electrodes simultaneously, and in which leads between terminals of the electrodes are arranged to avoid touching with the contact portion. This simplifies the switch, allowing it to be smaller and more durable.
