Abstract

1424380 Automatic positioning INTERNATIONAL BUSINESS MACHINES CORP 13 Dec 1973 [26 Dec 1972] 57882/73 Heading G3N [Also in Division B6] A serial printer has a document support (cylindrical platen 13) and a printing mechanism (golfball 11) which are relatively movable linewise and characterwise. Sensors 43, 54 detect respectively rotational movement of the platen 13 and lead screw 17. Thus the character and line position of the printer is compared with character and line position data specified by manual input to the panel 60. A discrepancy between the actual position and the specified position is then remedied by the control circuit actuating motor 50 and line feed mechanism. As shown the panel 60 has rows 71 and columns 77 of conductive bands. A membrane 69 has holes 63b corresponding to each intersection of the bands 71, 77. To specify a particular character and line position probe 64 is inserted in the selected hole 63b. Thus two circuits are closed as one of the bands 71 is pressed against plating 73 and one of the bands 77 against plating 75. Encoders 81, 91 translate these circuit closures into binary code. A switch within the probe 64 is closed when it is pressed into a hole 63b. This switch closure gates the input to registers 83, 93. Comparison circuits 85, 95 compare the output of the registers 85, 95 and the coded output of the sensors 43, 54. Depending on the discrepancy, directional commands issue to feed 40 and motor 50. When the desired and actual positions coincide, the gates 84, 94 output to stop the motor 50 and feed 40 and actuate a detent 51 on the ratchet 52.
