Abstract: A transducer track selection apparatus is disclosed enabling an operator selected coarse adjustment of a desired transducer position to be translated into a fine adjustment to a precise track location. The operator actuated coarse adjustment portion of the invention includes a track selector knob having a plurality of teeth radially positioned along the circumference thereof. These teeth are engageable with an externally mounted detent tooth so that the knob may be coarsely adjusted and held in one of the plurality of positions. Also connected to the knob is a shaft having a windlass rigidity mounted thereon. A cable in relatively high tension is wrapped around the windlass for movement thereby and is also connected to a transducer carrier, such as a magnetic head carrier, through a position compensator so that rotational movement of the coarse adjustment knob is translated into movement of the transducer, such as a maganetic head. A toothed rack is engageable with a single tooth on the head carrier and is disengaged from the head carrier by depression of the coarse selector knob against a spring bias, enabling rotation of the knob for making the coarse selection of desired head position. Upon release of the knob the toothed rack engages the single tooth on the head carrier providing a precise location of the magnetic head.
Abstract translation: 公开了一种换能器轨道选择装置，使得操作者能够将期望的换能器位置的粗略调整转换成对精确轨道位置的精细调整。 本发明的操作者致动粗调部分包括轨道选择器旋钮，其具有沿其圆周沿径向定位的多个齿。 这些齿可与外部安装的止动齿接合，从而可以将旋钮粗调并保持在多个位置中的一个位置。 还连接到旋钮的是具有安装在其上的卷扬机刚度的轴。 相对高张力的电缆缠绕在卷扬机上以便移动，并且还通过位置补偿器连接到诸如磁头载体的换能器载体，使得粗调钮的旋转运动转换成换能器的运动 ，如一个魔法头。 齿形齿条可与头架上的单个齿接合，并通过按压粗略选择旋钮的弹簧偏压而脱离头架，从而能够旋转旋钮以进行所需头部位置的粗选择。 在释放旋钮时，齿形齿条与磁头托架上的单个齿啮合，提供磁头的精确位置。

Abstract: An apparatus for receiving documents which tend to kite and/or curl upon being fed thereinto. The apparatus is made up of an elevatable platform which reduces curling problems upon low velocity feeding, and document elevatable wings which trap the leading edge of each document and overcome any curling and kiting problems during high velocity feeding.

Abstract: There is disclosed an envelope hopper for attachment to a printer requiring envelopes. Spring members provided with adjustable throats for permitting passage of a single envelope are biased downward against the upward force of the supply stack for compensating for changes in relative position of the uppermost envelope and the throats during separation from the stack.
