摘要： A small-sized printer having print characters circumferentially disposed around a plurality of print rings rotating by a motor on a common shaft, includes a detector comprised of an integrated circuit board rotating on the same shaft. The rotating circuit board incorporates conductive foil contacts which are sensed during rotation by fixed brushes, thereby providing a series of pulses indicative of the rotational position of the shaft and of the print characters which are in position for printing. An auxiliary signal, generated by additional contacts on the rotating circuit board, indicate positions between the print characters on the print rings. Logic circuitry combines the actual position pulses with the auxiliary signals to output converted position pulses which are free of noise and irregularities in waveform normally associated with brush contact switches. These converted pulses provide accurate timing as is required for the print cycle. A motor stop signal is also provided.

摘要： A miniaturized printer wherein the duration of each print cycle, the sequence of printing operations performed in each print cycle and the time between each print cycle is controlled by a detecting arrangement. The detecting arrangement is adapted to detect the rotary position of a plurality of print rings having print characters circumferentially disposed therearound and for generating a character selection timing pulse for each of the available rotational positions of each print ring during a print cycle. The rotational position of each print ring corresponds to a print character circumferentially disposed about the print ring and, to this end, a print selection mechanism associated with each of the print rings selectively positions each of the print rings at respective predetermined print positions during each print cycle in response to the character selection timing pulses produced by the detection arrangement so that printing can be performed thereby. The detecting arrangement is further constructed and arranged to produce a stand-by signal representative of each print ring being positioned at a stand-by position at the end of each print cycle. The detecting arrangement further includes a shutter mechanism for preventing the detecting arrangement from producing a stand-by signal until a predetermined interval of time after the last of the character selection timing pulses are generated during each print cycle.

摘要： An improved printer comprising a plurality of character rings provided with a plurality of characters on the respective peripheries thereof and corresponding pluralities of ratchet wheels and pawls. Each ratchet wheel is radially mounted on a character ring and a corresponding pawl is oscillatably mounted for engaging its corresponding ratchet at a preselected interval for stopping its associated character ring when a selected character is located at a predetermined position. Guides are provided for determining the constancy of oscillation of the pawls. Each pawl is spring driven into engagement with a corresponding ratchet wheel and a normal bias toward a corresponding ratchet wheel is provided. A releasable restraint acts oppositely to the bias on the pawl for normally preventing the pawl from engaging with its corresponding ratchet wheel. An electromagnetic device is provided for transducing an electronic signal into a mechanical motion which releases the restraint on the pawl whereby the bias on the pawl drives the pawl into engagement with its corresponding ratchet wheel and the character ring associated therewith is thereby fixed for aligning a preselected character in the strike path of an actuable platen. At a print command the platen abuts the character in its path and a paper or like imprint receiver is provided with an imprint of the preselected character.

摘要： A plurality of type carriers having spaced type characters and stop teeth thereon are yieldably driven past a printing station and are arrested by engagement of electromagnetically controlled stop pawls with selected ones of the stop teeth. The type characters and stop teeth on certain of the type carriers are staggered relative to the type characters and stop teeth on other type carriers to reduce the mechanical ''''break-away'''' load and the electrical load.

摘要： A cyclically operable high speed data printer comprising a plurality of type wheels supported and yieldably driven by a drive shaft, each wheel having character position stops and a home stop. The drive shaft is driven through two revolutions in the same direction for each cycle. During the first revolution, stop devices are spring actuated at different times to engage certain of the character position stops to arrest the type wheels in different type printing positions. Printing occurs after the first revolution, and during the second revolution, the stop devices are positioned to arrest the home stops whereby to locate the wheels in their home positions.

摘要： The keys of a typewriter effect the energization of selected electromagnetic windings whose cores are displaced steps of different length. The cores are connected to a control element which is displaced a distance corresponding to the total of the steps made by the cores. The displaced control element sets the type head to a selected position in which a selected type face, associated with the operated key, is operative.
