    摘要： The typewriter comprises a character carrying daisywheel having flexible petals which is carried by a carriage that is movable transversely with respect to the platen roller. Mounted on the carriage are a motor for moving the carriage, a motor for character selection, a print hammer, a cartridge for the typing ribbon, a correction ribbon and a drive unit for advancing the typing ribbon and raising and advancing the correction ribbon. The structure of the hammer and the arrangement of the typing ribbon and the character carrying daisywheel are such that typing and reading of the line of print are possible without it being necessary for the typing ribbon to be raised. The carriage is displaced in the two directions from the current position to an intermediate position to the left of the desired position. The carriage is then positioned precisely by a tooth-type setting means after a undirectional displacement of the displacement motor.

    摘要翻译： 打字机包括具有柔性花瓣的带有菊花的字符，该花键由可相对于压纸辊横向移动的托架承载。 安装在托架上的是用于移动托架的马达，用于字符选择的马达，打印锤，用于打字色带的墨盒，校正色带和用于推进打字色带并提升和前进校正色带的驱动单元。 锤子的结构以及打字带和携带菊花轮的人物的布置使得打印行的打字和读取是可能的，而不需要提高打字色带。 滑架在从当前位置到期望位置的左侧的中间位置的两个方向上移位。 然后在位移电动机的不定向位移之后，通过齿型设置装置精确地定位滑架。

    摘要： An incremental impact printer of the dot matrix type. Binary words representative of data to be printed along a line of print may be accepted from either the printer keyboard or the output of a computer or other source. The printer electronics provides for either a single character or a burst of characters to be substantially instantaneously printed upon receipt. The print head is always moved to the right of the last character printed to facilitate observation of that character. The next character is printed by first moving the print head to the left of the last character printed and then abruptly reversing the print head to print one or a burst of characters "on the fly". A novel registration system serves the dual function of accurately locating the proper position for a character to be printed and determining the direction of movement of the print head at any given instant. The printer has a capability of receiving characters at a rate of 75,000 characters per second and of printing at a rate of up to 120 characters per second. The device can also be utilized in the transmission mode with the transmission rate through communication of other links being a function of the operator's typing speed. The printer is further capable of simultaneously accepting data while performing a printing operation.

    摘要： A high speed serial printer having a platen or backing for print-receiving media and printing members for effecting display of indicia in printing lines on the media, including a print head having a printing end and selectively operable printing members; motion translation mechanism for oscillating the printing end of the print head laterally relative to the platen from a starting position for the length of a printing line and return to the starting position, which includes a pivot for the print head having an axis of rotation perpendicular to the plane of lateral movement of the print end, and drive mechanism for oscillating the print head about the pivot to minimize the force required to move the printing end of the print head, swinging of the print head on a pivot being materially more efficient than sliding the entire print head along a printing line.

    摘要： In a back printer print hammers impact the document against type characters formed on upwardly projecting fingers of a steel band. The fingers are backed by a platen which is removable from the print position to permit inspection of the printed information through spaces between the fingers as the band moves along the print line.

    摘要： An image forming device for connection to first and second external devices, including a control unit having an alternate operation mode for performing alternating communication with external devices by switching communication at a predetermined cycle. During communication with one of such external devices, the control unit enables reception of commands and/or a print-start signal from that external device and refuses reception of commands and a print-start signal from another external device. When communication is changed over from one external device to another external device, the control unit provides an interval in which reception of commands and a print-start signal from both external devices is refused for a predetermined period of time.
