Abstract
1469586 Printers INTERNATIONAL BUSINESS MACHINES CORP 11 Nov 1974 [26 Dec 1973] 48622/74 Heading G4H A serial printer comprises a movable print element mounted on a carrier itself movable past a plurality of print positions along a print line of a document, the print element having two or more arrays of type characters, each array containing all of a group of commonly used characters and part of a group of less frequently used characters, the print element and carrier being driven so that normally only one of the arrays is presented to a particular print position and other arrays are presented to successive adjacent print positions, there being a print hammer operable to effect impact of a selected type character with the document, and means responsive to the positions of the type characters in the arrays and to a character which is to be printed in a particular print position to inhibit drive of the carrier when the character to be printed is not in the next array to be presented to the print position. As disclosed, drive of the carrier is also inhibited if the distance between successive characters to be printed in their respective arrays is not large enough to allow time for hammer recovery. The print element is shown as a wheel of flexible radial tabs but may be a belt or drum instead. Index pulses from the wheel drive a type counter which indirectly drives an array counter, each character to be printed being used together with the array counter output (specifying the next array) to address a look-up table to determine if the character is in the next array and if so its position. The position of the previous character to be printed, stored in a register, is compared with the type counter output to control hammer firing. The positions of these two successive characters are subtracted, and added to the array length, the result being compared with the hammer recovery time. If there is not enough time, or the latter of the two characters is not in the next array, hammer firing is inhibited and the carrier is stopped, until printing can be resumed. Carrier velocity is always the same when the hammer is fired.
