    摘要： Paper is carried on an apertured platen and is rotated past a slowly moving printing head so as to scan in a raster fashion from top to bottom and from left to right over the surface of the paper. The paper is held to the platen drum by a vacuum that is applied to the inside of the platen. A valve is located at the entrance of the vacuum system of the platen in order to rapidly dissipate the vacuum so as to release or remove the paper from the still rapidly rotating platen. To facilitate inserting and releasing paper, a shroud system is placed very close to the periphery of the drum and guides the paper during insertion to close proximity with the vacuum. An exit door is provided in the shroud at a convenient location to permit the paper to exit from the drum once the vacuum has been dissipated. The size of the drum is made such that its circumference is slightly less than the length of the paper so as to provide overlap of the top and bottom edges of the paper. A light beam is directed tangential to the platen and is blocked once per revolution by the projection of flap of the overlapping edge of the paper. A photocell is placed opposite the light source and senses the temporary blockage of the light beam by the overlapping edge of the paper as the platen rotates.

    摘要： A closing mechanism 30 for a cabinet cover 14 is described including a pair of elongated flat links 32, 34 joined for sliding pivotal engagement. The remaining end of a first link 34 is pivotally secured to the enclosure cover 14 and the remaining end of the second link 32 is pivotally secured to the cabinet base 12. The links, when in their aligned position, are selectively locked in position by a cooperating notch 44 and tab 56. An articulated biasing means 59 in the form of two articulated coil springs 60, 62 serves to bias the links 32, 34 toward their axially aligned positions thus urging the cover 14 to its open position. The coil springs 60, 62 are hooked together with the remaining end of the second coil spring 62 hooked to a lip 20 on the cabinet base 12 adjacent the cover hinge 16. The remaining end of the first coil spring 60 is hooked to the link 32.
