摘要： A plurality of sheets stacked on a lifting plate are fed to a separator plate and separated so that only a single sheet will be transported with the rotation of a feed roller. The single sheet is transported downstream in a sheet feeding direction. When the single sheet has been transported to a target position reaching a transport roller and a pinch roller, a sheet aligning/pressing portion and a separator plate pressing portion displace the remaining sheets in a direction away from the feed roller. This causes an abutting portion to move away from the feed roller, and prevent the remaining sheets from moving downstream in the sheet feeding direction.

摘要： A support structure for ink cartridge eliminates potential obstacles in replacement of an ink cartridge, thereby facilitating the replacement. The support structure includes a carriage (2) which has a rear wall (2a) for supporting a rear surface of an ink cartridge (1), a base for supporting a bottom surface of the cartridge (1), and a first lateral wall (2b) for supporting a first side surface of the cartridge (1). The structure also includes a front cover (5) connected to the carriage (2) openably and closably in a horizontal direction. The cover (5) presses a front surface of the cartridge (1) toward the rear surface, and presses a second side surface of the cartridge (1) toward the first side surface. Further, the structure includes an upper cover (7) connected to the carriage (2) openably and closably in a vertical direction. The cover (7) presses an upper surface of the cartridge (1) toward the bottom surface.

摘要： An ink jet printer has two first driven rollers (A) disposed at a most upstream position in a secondary scanning direction, two first driven rollers (B) disposed at an intermediate position in the secondary scanning direction, and a single first driven roller (C) disposed at a most downstream position in the secondary scanning direction. The pressing force on a trailing edge of the recording sheet (10) is dividedly released in three steps sequentially and, accordingly, the nipping force and feeding force working on the recording sheet (10) also vary stepwise. Load fluctuations that occur at the moment the trailing edge of the recording sheet (10) is released from the nipping force of the first transport roller (4) also vary stepwise, whereby it is not possible that the feed precision is disturbed in a moment.

摘要： A paper conveying apparatus, having a simple structure, in which variation in a load imposed on paper is reduced to suppress printing irregularities, and also a printer are provided. A pair of rollers of a second conveying apparatus, arranged at a predetermined interval away from a first conveying apparatus, are composed of a rotationally-driven driving roller and a driven roller which is trailingly rotated, with paper being gripped between the driving roller and the driven roller. The pairs of rollers of the second conveying apparatus are arranged in different positions along the paper conveying direction. The paper gripping pressure of the pair of driving rollers arranged on the upstream side along the paper conveying direction is set to be lower than that of the other pairs of driving rollers.

摘要： An object of the invention is to provide a less costly print head maintenance mechanism featuring a compact, simple construction and negating the need for a widthwise increase of space for permitting vertical movement of the print head maintenance mechanism. The mechanism is designed to utilize the rotation of first cams and second cams for switching cap holders and wiper holders to a printing mode position for permitting a normal printing operation, a capping mode position for sealing a nozzle surface at a print head with the cap, and a wiping mode position for cleaning by wiping the nozzle surface with the wiper.

摘要： A printer apparatus in which its apparatus main body's width dimension can be minimized, by achieving compact housing of a maintenance station for performing maintenance operations with effective use of the space existing at both ends of a printing region. There are maintenance stations separately arranged as left- and right-hand portions at both ends outside the printing region. The maintenance station provides: a capping mode for capping a nozzle of the printing head; a wiping mode for wiping the nozzle of the printing head; and an ink spitting mode for preventing clogging of the nozzle of the printing head, and also the maintenance station includes a waste ink collecting bath for collecting ink discharged during the ink spitting mode.
