Adhesive Base Tape Feeding (only for laminated tape cassettes)
A laminated tape cassette contains both a transparent laminated tape roll and a separate
adhesive base tape roll.
When a transparent laminated tape and an adhesive base tape pass through the contact point
(between the tape feed roller and tape feed sub roller), they are then bonded together into a
single, printed tape. The ink printed on the laminated tape is, therefore, sealed up with the
adhesive base tape.
Ink Ribbon Feeding (except for AV labels cassettes and stamp tape cassettes)
As the main motor rotates, the ribbon drive cam located at the middle of the gear train rotates
counterclockwise. When fitted on the ribbon drive cam, the ribbon take-up roll in the tape
cassette also rotates to take up the ink ribbon.
To apply proper tension to the ink ribbon between the platen and the ribbon drive cam, the feed
amount of the ribbon drive cam is slightly greater than that of the tape feed gear. The
difference between the feed speeds at the platen and at the ribbon drive cam is absorbed by
the clutch spring which is integrated in the ribbon drive cam and allows the cam to slip.
This way, the ink ribbon is kept tense, which enables the ribbon to clearly separate from the
tape at the stabilized angle after printing.
