Abstract

Vernier adjustment of readhead 10 relative to card aligning rail 60 is facilitated by a clamping arrangement between tape drive drum 18 and detent wheel 36. The latter is keyed to shaft 16 which can be manually rotated via knob 15. Drum 18 and wheel 36 have half collars 48 and 56, respectively, which are connected together by screws 57, only one being shown. Adjustment in either direction is made by loosening one screw 57 and tightening the other. This causes drum 18 to rotate about shaft 16 because wheel 36 is held in position by detent roller 38. This movement of drum 18 displaces drive tape 30 without rotating knob 15. Calibrate lines 58 facilitate making the desired adjustment. Further details of the positioning and indicating mechanism are contained in the IBM Technical Disclosure Bulletin, December, 1967, Pg. 982.

Tape Drum Adjustment Device

Vernier adjustment of readhead 10 relative to card aligning rail 60 is facilitated by a clamping arrangement between tape drive drum 18 and detent wheel 36. The latter is keyed to shaft 16 which can be manually rotated via knob 15. Drum 18 and wheel 36 have half collars 48 and 56, respectively, which are connected together by screws 57, only one being shown. Adjustment in either direction is made by loosening one screw 57 and tightening the other.

This causes drum 18 to rotate about shaft 16 because wheel 36 is held in position by detent roller 38. This movement of drum 18 displaces drive tape 30 without rotating knob 15. Calibrate lines 58 facilitate making the desired adjustment.
