Abstract: A manually operated typing device comprises a pistol-shaped housing which is formed with a hollow space at the rear part for receiving the tape magazine, is formed with another hollow space at the middle part for receiving a typing handle, is formed with an extension from one of the both side walls for supporting a rotary disc and further is formed with a tape guiding groove on the longitudinally extending upper portion, a rotary disc rotatably supported on said extension from the side walls, said rotary disc being formed with a series of substantially square holes along the periphery, a plurality of typing head assemblies displaceably disposed in the respective substantially square holes of said rotary disc, a hammer member adapted to depress the selected typing head assembly, a typing handle arranged rotatable about a pivotal pin which is extended between the both side walls of the housing, said typing handle being pivotally connected to said hammer member at the front end thereof, a ratchet wheel operative

Abstract: A printhead assembly for a typewriter of the kind that swipes a printhead along a ribbon in producing marks on a receiving medium, is mounted to pivot and includes a ribbon guide that serves to wrap the ribbon around the trailing side (for a forward printing direction) of the printhead. The assembly is positioned to permit the printhead to be rotated to a normal printing position at a printing line. By so arranging the ribbon path that the ribbon directions for arrival and departure of the assembly intersect the pivot axis, essentially zero resultant torque may be applied to the assembly by ribbon tension forces and the printing pressure at the receiving medium is, accordingly, unaffected by ribbon tension variations.
