    • An improvement in movement of the recording section in a recording apparatus such as a typewriter, a printer or the like is provided. This recording apparatus comprises: a print ribbon cassette having a recording material; a carriage having a solenoid or a cam for moving the cassette; a detector for detecting the vertical or horizontal moving amount of the cassette; and a controller for controlling the moving condition of the cassette moved by the carriage on the basis of an output from the detector. The moving time of the ribbon cassette is changed in accordance with the typing speed of the operator or the size of character to be recorded. Thus, the whole printing time can be shortened and the noise generated in association with the typing operation can be reduced.
    • 提供了诸如打字机,打印机等的记录装置中的记录部分的移动的改进。 该记录装置包括:具有记录材料的打印色带盒; 具有用于移动盒式磁带的螺线管或凸轮的滑架; 用于检测盒的垂直或水平移动量的检测器; 以及控制器,用于基于来自检测器的输出来控制由托架移动的盒的移动状态。 色带盒的移动时间根据操作者的打字速度或要记录的字符的大小而改变。 因此,可以缩短整个打印时间,并且可以减少与打字操作相关联的噪声。

    • The apparatus of the present invention is provided with a stain preventing element provided between a print drum and a hammer and adapted to shield alternate digits to be printed, said stain preventing element being shiftable in the transverse or advancing direction of print sheet. Said hammer is an intermediate hammer which is set to a predetermined initial position from an unsteady position upon the turning on of the power supply, and simultaneously necessary preparations such as paper feeding and ink application onto the print drum prior to the printing are performed. Also there is provided a stain preventing mechanism for multi-color printing, and the above-mentioned stain preventing member is provided with a means for preventing ink diffusion. Also the paper feed plunger etc. is structured similar to the said hammer thereby rendering the entire apparatus smaller and more compact.
