摘要： The ink ribbon feed mechanism comprises a pair of spool shafts adapted for carrying ribbon spools, a pair of feed pawls selectively engaged with one of the ratchet wheels on said spool shafts for imparting intermittent rotation to the spool shafts, and a reverse mechanism for changing the engaging state of the feed pawls relative to the ratchet wheels. The reverse mechanism includes a first member movable from one to the other direction through a connecting member which is adapted to rotate in unison with the ratchet wheel in dependence upon an operation of a sensor for indicating that reversal of the ribbon take-up direction is required, a second member movable from one to the other position after travel of the first member through a predetermined distance, for changing the engaging state of the feed pawl, and first and second detent members being provided for positioning the members in their two positions. The second movable member is forcibly movable from one to the other position at the same time that the first member is moved from one to the other position by cooperation of the first member and the first detent member, whereby the engaging state of the pair of feed pawls relative to the ratchet wheels may be smoothly changed for reversing the ink ribbon take-up direction.
摘要翻译：色带馈送机构包括一对适于携带色带卷轴的卷筒轴，一对进给爪选择性地与所述卷筒轴上的一个棘轮啮合，用于给卷筒轴进行间歇旋转;以及反转机构，用于改变进给棘爪相对于棘轮的接合状态。反转机构包括可以从一个方向移动到另一个方向的第一部件，该第一部件通过连接部件，该连接部件适于与棘轮一致地旋转，这取决于传感器的操作，该传感器用于指示需要反转卷带方向，第二构件，其在第一构件行进预定距离之后从一个位置移动到另一位置，用于改变进给爪的接合状态;以及第一和第二制动构件，用于将构件定位在其两个位置。第二可移动部件可以通过第一部件和第一棘爪部件的配合而在第一部件从一个位置移动到另一个位置的同时被强制地从一个位置移动到另一个位置，由此一对进给的接合状态可以平滑地改变相对于棘轮的棘爪，以便反转墨带卷取方向。

摘要： An impact printer utilizing a ribbon mounted to be drawn past a print station and including means for reversing the direction of ribbon movement. The ribbon is terminally secured to first and second rollers mounted on opposite sides of said print station and of sufficient length to be wound around each of said rollers through many turns. Drive means are provided for selectively driving either the first or second roller. When the first roller is driven, it draws the ribbon from the second roller past the print station. Similarly, when the second roller is driven, it draws the ribbon from the first roller past the print station. The ribbon normally unrolls from the nondriven roller along a path tangential to the circumferential surface thereof. As the ribbon continues to be drawn from the nondriven roller after the last turn has been unrolled, its path changes to substantially perpendicular to a tangent to the roller circumferential surface, i.e., in line with a diameter of the roller. Means mounted adjacent to each of the rollers is able to sense the path change and thereafter reverse the roles of the driven and nondriven rollers to thus reverse the direction of ribbon movement past the print station.
摘要翻译：一种冲击式打印机，其利用安装成经过打印站的色带，并包括用于反转色带运动方向的装置。丝带终端固定到安装在所述打印台的相对侧上的第一和第二滚子，并且具有足够的长度以绕过每个所述滚筒多圈。提供驱动装置用于选择性地驱动第一或第二辊。当第一个辊子被驱动时，它从第二个辊子拉出色带通过印刷站。类似地，当第二辊被驱动时，它从第一辊拉出色带通过印刷台。丝带通常沿着与其圆周表面相切的路径从非驱动辊展开。随着丝带在最后一个转动已经展开之后继续从非卷轴辊被拉出，其路径变化为基本上垂直于滚子圆周表面的切线，即与辊的直径一致。靠近每个辊安装的装置能够感测路径变化，并且此后扭转从动辊和非卷绕辊的作用，从而使带运动通过印刷站的方向反转。
