ABSTRACT:
A rotating plate (36) which is rotated by raising a strap (39) upward by pulling the strap (39) is provided on the outer periphery of a strap feed and take-up drum (30) of a clip-carrying bookmaker. An operating drum (39) provided with a plurality of sawtooth-shaped projections (40) on the end surface thereof and rotated when the rotating plate (36) is rotated is provided. A ratchet (42) fixed to the support shaft (31) of the strap feed and take-up drum (30) is provided inside the operating drum (39). On the other hand, a coiled spring (48) urges the operating drum (39) so that the sawtooth-shaped projections (44) of the end surface thereof are meshed with the sawtooth-shaped projections (40) of the operating drum (39) constantly, and an operating drum (43) restricted in circumferential rotation is provided. Further, a ratchet (45) to be meshed with the ratchet (42) is provided inside the operating drum (43). Thus, the clip-carrying bookmarker of the invention can eliminate a rewind of the strap irrespective of a user's intention, removal of the clip due to an engagement of an operating shaft with other article, etc.
