Abstract
Abstract A flexible wire with an input end and an output end extends through an arcuately bent tubular guide that has an input end portion, an output end portion and an arcuate connecting section. The output end portion of the guide is relatively secured. Its input end portion is mounted for movement longitudinally of the guide. A restraint is arranged about the input end portion of the guide and has a first condition in which said input end portion is secured from moving and a second condition in which the output end portion is free from restraint to permit guide movement. The wire and guide are proportioned such that a force applied to the input end of said wire axially thereof will (1) cause the wire to slide through and thereby project the output end of said wire from the output end portion of the guide, if the restraint is in said first condition; and (2) cause the guide to extend at its arcuate section in a direction away from the output end of said wire in consequence of frictional coupling of the guide and wire, if the restraint is in said second condition. This switching phenomenon is employed in a recorder having means for applying an oscillating force simultaneously to an input end of each wire in an array of flexible wires which respectively are arranged through arcuately bent flexible tubular guides. The input end portion of each guide is arranged for selective restraint, and release from restraint, in a fixed position such that: 1. WHEN RESTRAINED, A RIGID PATH IS PROVIDED FOR THE ASSOCIATED WIRE BY SUCH GUIDE AND, ALTERNATELY DURING RESPECTIVE PHASES OF EACH OSCILLATORY CYCLE, THE OUTPUT END OF THE WIRE WILL BE (A) FIRST PROJECTED FROM THE OUTPUT END PORTION OF THE GUIDE INTO PRINTING POSITION RELATIVE A RECORD CARRIER, AND (B) THEN WITHDRAWN; AND 2. WHEN FREE OR RELEASED FROM RESTRAINT, ALTERNATELY DURING RESPECTIVE PHASES OF EACH OSCILLATORY CYCLE, SUCH GUIDE AND ITS ASSOCIATED WIRE (A) FIRST BECOME FRICTIONALLY COUPLED AND BEND TO CAUSE ELONGATION OF INTERMEDIATE PORTIONS THEREOF WHICH ARE REMOTE FROM THE OUTPUT END OF THE WIRE, THEREBY TO PREVENT ITS PROJECTION INTO PRINTING POSITION, AND (B) THEN RETURN TO ORIGINAL POSITION. A character generator produces effects which are representative of the characters to be reproduced. It is coupled to restraining assemblies for the guides, whereby, simultaneously in one phase of each oscillatory cycle, selected wires will be projected for printing and the remaining wires will be prevented from printing.
