Abstract
A tape reel device includes a spool in the form of a hollow cylinder having a hollow portion for winding a tape material around a peripheral surface thereof, a casing rotatably accommodating the spool, and a braking mechanism in sliding contact with the spool. The baking mechanism applies back tension to the tape material being rolled out from the spool. The braking means comprises a sliding-contact member brought into contact with the spool in an axial direction such that the spool is circumferentially slidable on the sliding-contact member, and a spring arranged within the hollow portion of the spool and supported by the casing for urging the sliding-contact member in the axial direction.
