Incrementing Tape Cartridge

The incrementing tape cartridge consists of an enclosing case 10 having a supply spool 12 and a take-up spool 14 rotatably mounted therein.

A paper tape 16 on the supply spool 12 passes around a post or roller 18 which is mounted in an opening 20 to the outside of the case, past a writing area 22, along the outside of the case to a second opening 24, around a post or roller 26 and onto take-up spool 14.

A slider element 28 is mounted in a slot 30 in case 10 for reciprocal movement, as shown by arrow 32. A pin 40 engages the slider and may be actuated by a suitable mechanism to provide the reciprocal motion. A spring arm 34 is fixed to slider 28 for reciprocal motion therewith and, due to its spring nature, rides on the outer diameter of the tape-up spool 14. The arm 34 has a barbed end 36 which slides on the tape and spool flange in movement to the left, but engages the inside of the flange on movement to the right to increment the tape.

An element 38 mounted on the case wall is in frictional engagement with the flange of spool 14 and is angled so as to inhibit counterclockwise rotation of the spool 14.

Alternatively, the take-up spool flange may be provided with very fine radial teeth and the barb then acts as a ratchet drive.
