摘要： An ink droplet detecting apparatus for use in conjunction with an ink-on-demand jet printer having a nozzle is provided. A first electrode is disposed at a predetermined position spaced from and facing the nozzle. A second electrode is positioned so that an ink droplet following a correct path will reach the first electrode and change the impedance value between the first and second electrodes. This change in impedance is detected and used in determining the presence of correct ink droplet path. The second electrode may be either positioned facing the nozzle in spaced adjacent relation to the first electrode or within the ink path upstream of the nozzle.

摘要： A small size ink jet printer includes a cover which presses against the ink nozzle openings when the printer is inoperative. The printer head is electrically driven but operation of the nozzle cover is at least partially performed manually. Particularly, the nozzle covering operation which needs a large force, is often manually performed to conserve energy and reduce component size. Circuits detecting and responding to an inadvertent failure to cover the nozzles are also provided.

摘要： A small printer for printing characters on a printing medium especially adapted for use in a portable electronic calculator. The printer includes a frame having a carriage slidably mounted thereon for lateral displacement across the printing medium. An ink jet printing mechanism is carried on the carriage for selectively printing characters at predetermined positions along lines of the printing medium. A crank mechanism couples a motor to the carriage so that the printing mechanism can be translated across the printing medium. A printing position control circuit determines when the printing mechanism is in each predetermined printing position and selectively supplies a printing signal to the printing mechanism so that the printing mechanism will print a character at the selected predetermined positions.
