Abstract
A correction tape dispenser has a front cover (10), a core assembly (20), an extending-and-retracting mechanism (30) and a rear cover (50). The core assembly (20) is mounted slidably in the front cover (10) and has a convex portion extending out of the front cover (10). The extending-and-retracting mechanism (30) selectively drives the core assembly (20) to hold forward or backward. The rear cover (50) is mounted on the front cover (50). A user pushes the core assembly (20) with the extending-and-retracting mechanism (30) forward to extend the head (24) out of or retract the head (24) into the front cover (10). Retracting the head (24) prevents dust from accumulating on a correction tape on the head.
