121	Ink jet printing apparatus	US307339	1981-09-30	US4393386A	1983-07-12	Peter C. Di Giulio
An ink jet printing apparatus is described wherein an array of ink jet heads of the impulse jet type is compled to print sheets such as envelopes traveling past the heads. The ink jet heads are spaced along the travel path of the sheets and laterally staggered to print different image lines. The apparatus includes a microprocessor and controllers which are associated with individual heads. The controllers include buffers which are loaded with image signals derived from a font memory in correspondence with data to be printed. Presettable delay networks are used in the controllers to precisely determine when an ink jet head is to be printed in relationship with the detection of sheets at a particular distance relative to the heads. The ink jets heads are operated in timed relationship with each other and in synchronism with the traveling sheets while their associated buffers are reloaded at the proper times for a continual printing of different information such as addresses on envelopes.
122	Optical sensing of wire matrix printers	US190772	1980-09-25	US4339208A	1982-07-13	Horst H. Biedermann
An optical sensor is provided for each print wire of a print head and includes two glass fibers to carry light from a light-emitting diode to the surface of a record medium and to carry the reflected light to a photodiode. Each printed dot is detected and the sensor output is compared with a delayed or stored print signal which is applied to the drivers for the print wires.
123	Dot printer head	US8637	1979-02-01	US4244658A	1981-01-13	Masahiko Mori
In a dot printer head, a small, thin and flat lever or chip pivots on a fulcrum when attracted by an electromagnetic coil. Pivoting of the chip on the fulcrum drives a needle, in opposition to a biasing spring, against an ink ribbon and paper for printing on the paper with dots. The biasing spring returns the needle after printing. The fulcrum is positioned by a resilient restraint comprising a leaf spring. The magnetic gap between the coil and chip is small but provides a long needle stroke because of the mechanical advantage in the pivoting element. The gap requires no adjustments. The printer head includes a plurality of similar independently operating needles and drive mechanisms.
