摘要： Printing platen for positioning a recording medium such as paper which includes an evacuated chamber having a slotted face plate for attracting, holding and guiding the paper. Slots are arranged parallel to each other and the direction of paper travel, and the vacuum attraction causes temporary deformation of the paper so that the slots can effect guiding and tension on the paper during advancement. Effective platen length can be varied to accommodate different paper widths.

摘要： Apparatus for incremental feeding of a paper web from an arborless supply roll over a transverse dancer bar resiliently supported at each end with the respective supports having different and variable spring rates to effect uneven pulling of the web during feeding and thus jogging of the supply roll. This action maintains a tight wrap of the outer layers of web on the roll and aids in maintaining web alignment during feeding.
摘要翻译：用于将纸幅从无轴承供应辊增加馈送到在每个端部处弹性地支撑的横向调节器条上的纸幅的装置，其中各个支撑件具有不同的和可变的弹簧速率，以在进给期间从而实现纸幅的不均匀拉伸，从而在供给辊上慢跑。该作用保持幅材外层的紧密包裹，并且有助于在进料期间保持卷材对准。

摘要： A printer has first and second print mechanisms separated by a gap for the passage of a print medium. The print mechanisms are mounted on relatively movable support members. A gap adjustment mechanisms has one set of cam means for moving the support members relative to each other for both forms loading and forms thickness adjusting. The cam means comprises a pair of elongate cam bars translatable along one support member and follower pins on the other member which are located in camming slots formed in the cam bars. The camming slots have first and second camming sections in the form of linear ramps with gentle and steep slope angles respectively. The cam bars are translatable by pinion gearing in engagement with rack gearing on the cam bars, the pinion gears being on a shaft rotatable by a knob to thereby cause the follower pins to be cammed by either the first linear ramp for forms thickness adjustment or the second linear ramp for forms loading.
摘要翻译：打印机具有由打印介质通过的间隙分开的第一和第二打印机构。打印机构安装在相对可移动的支撑构件上。间隙调节机构具有一组凸轮装置，用于相对于彼此移动支撑构件以用于两种形式的装载并形成厚度调节。凸轮装置包括可沿着一个支撑构件平行移动的一对细长凸轮杆，另一个构件上的从动销位于形成在凸轮杆中的凸轮槽中。凸轮槽具有分别具有平缓和陡峭倾斜角的线性斜面形式的第一和第二凸轮部分。凸轮杆可以通过与齿轮传动装置啮合的小齿轮传动装置平移在凸轮杆上，小齿轮位于可由旋钮旋转的轴上，从而使从动销由用于形式厚度调节的第一直线斜面或用于表单加载的第二个线性斜坡。

摘要： Apparatus for use with a printer which has a pair of tractors that engage sprocket holes in the paper to adjust for different paper widths or to adjust the lateral position of the paper. The apparatus comprises a pair of coaxial lead screws, one attached to a rotatable shaft and the second rotatable on the shaft adjacent to and relative to the one lead screw. One tractor is coupled to each lead screw. Rotation of the one lead screw is obtained by a knob keyed to an end of the rotatable shaft. Rotation of the second lead screw is prevented during rotation of the knob by spring loaded fingers with detent elements engageable with detention gearing on the end of the second lead screw. Rotation of both screws is obtained by rotation and axial movement of the knob on the shaft so that a cam surface on the knob engages cams of the spring fingers to disengage detent elements from the detention gearing and drive gearing on the knob engages drive gearing on the second lead screw.
