摘要： In a printer using print hammers covering two adjacent print positions, random firing of the print hammers is made possible by using additional storage means for storing three bits for each print position. When a print hammer is fired for one of a pair of associated print positions, a bit is loaded into the storage for the other of the associated print positions and the bit count is advanced each time the hammer is optioned to fire for the associated print position. When the bit count reaches 0 0 0 the print hammer may be fired again. For an intermediate count firing of the print hammer is inhibited.

摘要： A printing device for electronic computors and the like comprises a printer drive circuit including a first group of printing coils for effecting printing of lower place figures and a second group of printing coils for effecting printing of higher place figures, and a switching mechanism for selectively switching print command signals to one of the first and second printing coil groups. The printing device includes means for selectively performing either a single printing operation with the energization of the lower place figure printing coils or two consecutive printing operations consisting of a first printing operation with the energization of the lower place figure printing coils and a second printing operation with the energization of the higher place figure printing coils by actuating the switching mechanism in accordance with a drive command signal.

摘要： A high speed printer of the chain type in which the type characters on the chain are spaced apart a distance greater than the distance between adjacent print positions and in which the number of firing hammers is less than the number of print positions such that each hammer services several print positions. The attachment or control for the printer maintains identity of the type character in front of a print position optioned to print by modifying a type character counter in accord with scan being taken, print position and position of the firing hammers.

摘要： Maximizing the printing rate of an electronic printer by causing it to print data characters at a relatively constant rate despite variations in the pattern of the incoming data. The number of characters in an incoming data pattern to be printed substantially simultaneously is monitored and the printing rate controlled within certain limits to provide a maximum printing rate consistent with the power and mechanical limits of the printer design.

摘要： A printer has a type cartridge with a plurality of characterbearing type levers, alternate levers having faces on the back at different levels. Print hammers for each print position have striking faces covering both levels, and selection of the type levers is made by operating an interposer between the printer hammers and type levers to the desired level.

摘要： The disclosure describes a printer in which characters are moved past a sheet support on an endless belt. Hammers move from a rest position to a strike position in order to strike the characters against the sheet. The time at which the hammers are moved from their rest positions so that the characters can be accurately struck irrespective of belt speed variations by means of a strike correction circuit arrangement which includes a first sensor means positioned with respect to the endless belt for generating a synchronizing pulse in response to the movement of a reference indicator on the belt past a first predetermined position and a second sensor means associated with the endless belt for generating a check pulse in response to movement of another indicator means on the belt past a second predetermined location. A logic circuit generates a signal representing
