Title:
REVERSE ROTATION PREVENTIVE MECHANISM AND RIBBON CARTRIDGE
Document Type and Number:
Japanese Patent JP3453213
Kind Code:
B2
Abstract:
PURPOSE: To control the vibration of a claw generated by an pressure sensitive adhesive during the normal rotation of a rotational member by sticking a thin plate coated with the adhesive to a main body through the claw in a rotation preventive mechanism equipped with the claw.
CONSTITUTION: A ratchet gear 17 is formed at one end of the circumferential surface of a take-up reel 12 for preventing the reverse feed of a ribbon 14, and two elastic claws 11b which engage with the ratchet gear 17 during the reverse rotation of the take-up reel 12 are installed to face each other directly in a main body 11. A thin plate 18, which was coated with a pressure sensitive adhesive, in which a hole larger than the ratchet gear 17 is formed in the middle is stuck on the inside of the main body through the claws 11b coaxially with the take-up reel 12. When a ribbon cartridge attached to the printer of a word processor is used, although the claws 11b vibrate by the ratchet gear 17 rotating normally with the take-up reel 12, the vibration of the claws is attenuated by the adhesion of the adhesive applied on the thin plate 18.
