Abstract
A tape reel device includes a cartridge case (20) rotatably accommodating a spool (22b) around which an ink ribbon (22a) is wound, and a brake (3) for providing back tension to the ink ribbon (22a) unwound from the spool (22b). The brake (3) includes a sliding contact member (35) in sliding contact with end surface of the rotating spool (22b), a coil spring (36) urging the sliding contact member (35) in shaft direction of the spool (22b), and a rotation restrictor (37) for restricting rotation of the sliding contact member (35). The rotation restrictor (37) includes an engaging portion protruded from the cartridge case (20) to be inserted into the sliding contact member (35), and a to-be-engaged portion (44) which is protruded from inner circumference of the sliding contact member (35) and with which the engaging portion engages in rotation direction of the spool (22b).
