Tape handling means

A system for automatically unwinding paper tape from a roll and feeding it to the output punch of a tape justifying computer. A 14-inch roll of tape without a reel is mounted upright on a hub on the outer wall of a soundproof housing enclosing the output punch. A pair of manually operable retainer members on the end face of the hub swing between inner release positions and outer effective positions to hold the tape roll in place. A roller on a pivoted arm rides on the tape roll and the traveling tape from the roll is turned 90 DEG in direction to a tape drive on the same housing wall, the tape drive feeding the tape to the tape punch inside the housing. The housing comprises a bottom wall and a separate removable box-like shell. The tape punch engages locating pins on the bottom wall and the shell interlocks with the bottom wall in proper relationship thereto for positioning the roll of tape and the tape drive on the housing shell accurately relative to the tape punch inside the housing.
