摘要： A sheet feeding apparatus, in which a drive motor rotates a pickup roller, and a drive transmission portion provided between the drive motor and the pickup roller transmits a drive from the drive motor to the pickup roller. During sheet feeding, one of the drive motor and the drive transmission portion causes the pickup roller to perform an intermittent drive of iterating the drive and a stop, so that a sheet is gradually deflected between the pickup roller and separation claws.

摘要： A device for supporting a print head includes a tabular print head capable of contacting a platen, the print head being mounted on a head-supporting plate retained by a supporting shaft. A central part of the supporting shaft is supported on a fixed receiver plate. The head-supporting plate is subjected to spring forces from two springs on both sides of the receiver plate. Side plates are provided with elongated grooves extending normal to a tangential direction at a contact point of the platen with the print head, and both ends of the supporting shaft extend through the grooves. Displacement takes place at both ends of the supporting shaft, corresponding to distortion and deflection of the platen in cooperation with the grooves. The laterally elongate print head uniformly contacts over its entire length against the platen with automatic equilibrium requiring no adjustment.
摘要翻译：用于支撑打印头的装置包括能够接触压板的平板状打印头，打印头安装在由支撑轴保持的头部支撑板上。支撑轴的中心部分支撑在固定的接收板上。头部支撑板受到来自接收器板两侧的两个弹簧的弹簧力。侧板设置有在压板与打印头的接触点处垂直于切线方向延伸的细长槽，并且支撑轴的两端延伸穿过槽。在支撑轴的两端处发生位移，对应于与凹槽协作的压板的变形和偏转。横向细长的打印头在其整个长度上均匀地接触压板，自动平衡不需要调节。
