Abstract

1,261,577. Selective printers. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP. 22 April, 1969 [22 April, 1968], No. 20606/69. Heading G4H. [Also in Division B6] A high speed printer comprises a plurality of type wheels 1 spaced uniformly along and disposed tangentially to the print line, said wheels rotating synchronously and each carrying four circumferential bands of type, being axially displaceable to bring a selected band into register with the print line, a hammer 3 behind the paper opposite each type wheel, means for moving the paper sideways to print all character positions of a line and means for advancing the paper after the printing of a line. The direction of the sideways movement is reversed in successive line printing operations. There may be eight type wheels each carrying four bands of 32 characters. They are driven from a common shaft 7 and can be individually raised to one of four levels by a pair of solenoids 67, 69 which are energized or not and act through a lever mechanism. The shaft 7 carries a pulse generator 8, 9 the pulses being used to indicate the angular position of the typeheads. The paper is mounted on sprocket bands 17L and 17R and these are displaceable left or right for example by a rotary thread 12 giving eight spacing positions. At each side there is a detector providing a signal indicating that the paper has reached the end of its travel in that direction and the direction of travel is then reversed. Data corresponding to a line of characters to be printed is entered into a circulating store via a buffer store. The stored line of characters is read out in an order corresponding to the direction of movement of the paper carriage.
