Abstract: A reversible typing ribbon cartridge has two pairs of pinch roll pairs for moving the ribbon in the direct and inverted positions respectively. When the cartridge is off the typing machine both pinch pairs are engaged with the ribbon, but as the cartridge is installed, a rod penetrates into the cartridge and disengages the pinch pair in the following position while drives engage the ribbon spool and the pinch pair in the leading position.

Abstract: A ribbon reverse mechanism for a high-speed line printer having a towel ribbon driven between a pair of spring-loaded spools by gear means coupled to band drive motor includes an input shaft coupled to the drive motor and having mounted thereon a pair of spaced-apart worms for driving respective gears. The gears are each coupled a wrap-spring clutch, housed within a clutch stop collar having a plurality of teeth engageable with a floating disk, to an output shaft coupled to the spools. Each of the floating disks are alternately engaged to its respective clutch stop collar, thereby permitting the wrap spring clutch to be wound up, through energization of a coil. As one spool becomes full, a ribbon direction sensor outputs a signal indicative thereof to a machine co-processor in order that the active engagement may be de-energized, while the inactive engagement coil may be energized for reversing the direction of ribbon travel.

Abstract: A microcomputer controls a ribbon drive assembly in a high speed wire matrix printer to eliminte ribbon slack, to insure proper ribbon positioning and to conduct diagnostics in conjunction with turning on the printer such as start-up time each day and after replacement of the ribbon with a new ribbon, the diagnostics checking to be sure that a ribbon is actually in the proper position, that it is threaded across the print line and also checking for proper operation of the ribbon drive, logic, and electronics. Tests are also made for proper ribbon drive during normal ribbon feeding operations.

Abstract: A device for detecting a travel condition of an inkribbon for printers is disclosed. The device is composed of a rotary member rotatable in response to the travel of the inkribbon and a signal generation means interlocked with the rotary member. The signal generation means generates a detection signal and can not only detect trouble of the detection device but also detect a mode in operation of a carrier on which the detection device is arranged as well as detect the travel of the inkribbon.

Abstract: A high-speed printer of the type having an inked ribbon traversing across a printing area and which is selectively movable to permit character impression and subsequent visibility of the character formed. A pair of pivoted cantilever arms are provided on each side of the printing area of the high-speed printer with a first ribbon guide being mounted adjacent the end of each pivoted cantilever arm. The inked ribbon is supported under tension between the two guides across the width of the printing area and pivoting means are provided for pivoting the cantilever arms in unison about a common pivot axis whereby the printing ribbon is selectively moved as a relatively rigid beam between the printing and viewing positions by pivotal movement of the cantilever arms. A second ribbon guide is mounted on each side of the high-speed printer for supporting the ribbon at points intermediate ribbon takeup and payout spools and the respective first ribbon guides. Each of the second ribbon guides are mounted with their peripheral surface supporting the ribbon in axial alignment with the pivot axis of the pivoted cantilever arm and the ribbon is twisted through substantially a right angle in the space between each second ribbon guide and its associated first ribbon guide so as to extend along a path that bisects the angular movement of the pivoted cantilever arms. Reversible, tensioning ribbon spool drive mechanisms are supported on opposite sides of the high-speed printer for moving the ribbon in either direction between the pair of takeup and payout spools. The spool drive mechanisms are selectively operable alternately to cause the spools to take up or pay out the ribbon and comprise rotatable supporting plates having driving and neutral freewheeling positions. A movable center gear and ratchet arrangement is supported on each supporting plate and coacts with a fixed center gear when the rotatable supporting plate is in its driving position. A spindle for supporting a ribbon spool is rotated by the fixed center gear and includes an actuable finger which is extended upon exhaustion of a ribbon from a spool under conditions where the spool is operating as a payout spool with the supporting plate in its neutral freewheeling position. An interposer lever is actuated by the extended finger upon exhaustion of the ribbon from the spool which then coacts with the ratchet to rotate the rotatable supporting plate from its neutral freewheeling position into a driving position thereby reversing the operation of the spool. A rotatable shaft interconnects the ribbon spool drive mechanisms on opposite sides of the printer with respective connecting links interconnecting the supporting plate of each spool drive mechanism with the rotatable shaft in a manner such that rotation of one of the supporting plates from the neutral freewheeling position to the driving position results in automatic rotation of the opposite supporting plate from the driving position to the neutral freewheeling position thereby providing jam-proof operation.
