摘要： The invention concerns a mechanism for raising and feeding different types of ink ribbons in typewriters and similar machines. With a simple design and using only one motor under programmed control, the mechanism is capable of utilizing ink ribbons economically, e.g. printing alternately in several printing zones of a ribbon or in several colors. It also feeds ribbon by a length which corresponds to the type of ribbon, or type of operation, e.g. proportional typing. The starting point for the various functions is a basic position to which the mechanism is positioned by the motor.

摘要： Function controlled raising and transporting mechanism for the selective control of a print ribbon or correction tape by means of a power drive and freewheeling clutches operative to effect print ribbon or correction tape transport incident to carriage motion in print direction only. In certain commanded functions such as spacing, tabulating, etc., both the print ribbon and correction tape transports are disabled by moving output elements of the freewheeling clutches to intermediate clutch disabled positions to thereby realize optimum utilization of the ribbon and tape capacities.

摘要： A drive system to raise and transport both print and correction ribbons on typewriters or like machines is powered by a single bidirectional stepping motor. In one direction of rotation the motor acts via a special action clutch to first drive mechanisms for raising a print ribbon and then to establish gear connections for driving mechanisms for transporting the print ribbon. In the other direction, the motor acts to establish gear connections for driving mechanisms for raising and transporting a correction ribbon.

摘要： A ribbon and correction tape are separately mounted on a typewriter for movement in closely spaced parallel planes from a position below a line of impact along a line of print to an elevated position opposite said line of print. To minimize interference and malfunctions during relative movement of the ribbon and tape during elevating movement of one, the ribbon and tape are supported at an acute angle to one another, thereby to move in scissor fashion relative to the other.

摘要： A device for monitoring paper feed movement in typewriters, printers or other paper-feeding apparatus, e.g. photocopiers wherein paper sheets inserted between a rotatable platen and pressure rollers are driven incident to rotation of the platen. A signal generator has a driving roll of the same size as the pressure rollers and axially aligned therewith which is prevented from being driven by the platen by the interposition of a narrow stationary belt positioned between the platen and drive roller adjacent one end of the platen. When paper is inserted a side edge passes between the belt and the drive roll and movement of the paper incident to platen rotation drives the drive roll of the pulse generator which monitors paper movement. If there is no paper movement due to paper jams or the end of a paper sheet is reached this condition is detected by the absence of pulses at the output of the pulse generator. The absence of pulse sequences serve to shut down the machine.
摘要翻译：一种用于在打字机，打印机或其他给纸设备中监视进纸运动的装置，例如打印机。其中插入在可旋转压盘和压力辊之间的纸张被驱动入台板的旋转的复印机。信号发生器具有与压力辊相同尺寸的驱动辊并与其轴向对准，通过插入位于压盘和驱动辊之间邻近压板的一端的狭窄的静止带而防止压板被驱动。当插入纸张时，侧边缘通过带和驱动辊之间，并且纸张入口到纸盘旋转的移动驱动监视纸张移动的脉冲发生器的驱动辊。如果由于卡纸而导致纸张移动不到位或纸张的末端达到，则脉冲发生器的输出端不存在脉冲来检测该状况。没有脉冲序列用于关闭机器。
