Abstract: Disclosed is a mechanism for shifting the rack of a selection mechanism for a single element printer from one position to another in timed relationship to the translation of a barrel cam which provides the necessary mechanical input to control the amount of rotation of the typehead. The control of the rack shift mechanism is a cam arrangement operated in timed relationship with the translating barrel cam to provide for the shifting of the rack at the beginning of each print cycle, if necessary, and the retaining of the rack in its shifted position at the completion of the cycle, thereby eliminating the necessity to provide for the time required to shift the rack back to its home position at the end of the cycle. The elimination of the restore operation of the rack provides more time during the cycle to operate the selection mechanism and accomplish printing or conversely provides for a smaller amount of time being required for the necessary functions thereby providing the capability of operating the remainder of the mechanism at a faster rate.

Abstract: Web cartridge (10) having a supply spool (12), a take-up spool (34) and a web extending from the supply spool (12) to the take-up spool (34) through exit (18) and the entrance (26) apertures to form an exposed portion of the web exterior to the cartridge. A beam spring (40) supported by the cartridge, has one end (44) positioned in squeegeeing relation to the convolutions of the web accumulated on the take-up spool (34) for forcing the web against the convolutions, the end (44) being positioned to be the only portion of the spring (40) engaging the web in order to remove buckles in the last convolution and thus preventing voids and wrinkles in the spool.

Abstract: Connected to the take-up spool (26) of the ribbon cartridge (10) is a disc member (28) supporting a pair of flexible arms (32) with outwardly oriented pointed ends (34). Ends (34) engage ratchet teeth (44) formed on the internal surface of a cylinder (42) forming part of, or attached to, the ribbon cartridge (10). As disc (28) and arms (32) are rotated by the ribbon feed mechanism, arms (32) will flex and permit a rotation of disc (28) and take-up spool (26) with a minimal drag force. Upon reversal, the ends (34) of arms (32) engage ratchet teeth (44) and arms (32) become compression columns resisting the rotation of disc (28) and spool (26). Ends (34) of arms (32) are positioned such that they are one-half tooth out of phase to ensure that one tooth is always in engagement with the end (34) of one of the two arms (32).

Abstract: A print mechanism is described which has a constant current driven solenoid (22) acting against an arch-shaped hammer (10) to power the hammer (10) through an arc of powered flight followed by an arc of free flight. The solenoid/hammer engagement point (24) removes the solenoid to a position which does not obstruct print line visibility and the hammer (10) rest position is withdrawn to improve print line visibility.
