摘要： A printer for performing recording successively while a recording head moves backwards and forwards in a predetermined direction with respect to a recording medium such as paper. A paper hold roller for pressing the recording medium against a platen in the vicinity of a recording area opposite to a print head is detachable from the platen in relation to the movement of a carriage for carrying the recording head. The presence and absence of paper is detected to control the paper feed. An ink ribbon is provided which has color zones and an ink absorption zone in the direction of the ribbon width for multi-color printing by shifting the ribbon in the width direction by means of the carriage movement so that a selected color zone faces the recording head. The printer further includes a ribbon cassette, means for controlling paper insertion and feeding and means for cleaning the recording head. Also included are a paper bail control, color zone selector and paper detector.
摘要翻译：一种用于在记录头相对于诸如纸张之类的记录介质沿预定方向向前和向前移动的情况下连续执行记录的打印机。用于将记录介质压靠在与打印头相对的记录区域附近的压板上的纸张保持辊相对于用于承载记录头的托架的移动而从压板可拆卸。检测纸张的存在和不存在以控制供纸。提供了一种墨带，其通过移动移动使色带沿宽度方向移动，使色带宽度方向上具有彩色区域和墨吸收区域，用于多色打印，使得所选择的色区面向记录头。打印机还包括色带盒，用于控制纸张插入和进纸的装置以及用于清洁记录头的装置。还包括纸张保释控件，色区选择器和纸张检测器。

摘要： An impact type dot head for forming a character, symbol or the like by a dot matrix comprises: four printing wires arranged in a line in a wire holder; a guide member to guide the wires in parallel; four drive units each for pushing the rear edge of the wire in its axial direction and allowing the front edge of this wire to be projected to the printing position; and a foredamper consisting of a silicone rubber serving as a vibration damping material attached to the holder along its side surface. The drive unit includes an armature to clap the rear edge of the wire and an electromagnetic member to attract the armature. Each printing wire comprises a long thin-diameter portion on the front edge side, a short thick-diameter portion near the rear edge side and an intermediate taper portion connecting them. A coil spring having a diameter which is larger than the diameter of the front edge of the wire and is smaller than the thick portion is elastically attached to the wire, thereby allowing the wire to be pushed and returned from the printing position to the original portion. The printing wires therefore can be accurately guided with a simple and inexpensive structure and printing noise can be reduced.
摘要翻译：用于通过点阵形成字符，符号等的冲击型点状头包括：在线保持器中以线排列的四条印刷线; 用于引导电线并联的引导部件; 四个驱动单元，每个驱动单元各自用于沿其轴向推动线的后边缘，并允许该线的前边缘突出到打印位置; 以及由用作缓冲材料的硅橡胶构成的前拉手，其沿着其侧表面附接到保持器。驱动单元包括用于拍击线的后边缘的电枢和用于吸引电枢的电磁部件。每个印刷线包括在前边缘侧上的长的细直径部分，在后边缘侧附近的短的粗直径部分和连接它们的中间锥形部分。直径大于线材的前边缘的直径并且小于厚度的螺旋弹簧被弹性地附接到线材，从而允许线材从打印位置推到原始部分。因此，能够以简单且廉价的结构精确地引导打印线，并且可以降低打印噪音。
