<p>A dispensing unit (20) for a thin film dispenser has a base (21), a wheel assembly (23), a thin film (26) and a locking device (28). The wheel assembly (23) is mounted on the base (21) and has a tape supplying wheel (24) and a used tape collecting wheel (25). The tape supplying wheel (24) and the used tape collecting wheel (25) are mounted rotatably on the base (21). The locking device (28) is resiliently disposed on the base (21) and selectively engages the wheel assembly (23) to prevent the wheel assembly (23) from rotating. Accordingly, the locking device (28) can provide a locking function to the wheel assembly (23) to prevent the thin film (26) from being loosened during the course of packaging, transporting and assembling processes.</p> |
