  • Publication number: 20220332534
    Abstract: The coating film transfer tool includes a feeding portion that feeds tape with a coating film, a transfer head that transfers the coating film from the tape onto a transfer target surface, a cassette to which the transfer head is fixed, and a head cap. Shaft portions are provided on either the head cap or the transfer head/cassette, and shaft bearing holes are provided on the other one. Due to relative rotation of the shaft portions, the head cap rotates between a closed position for covering the transfer head and an open position for exposing the transfer head. The distances from the rotation axis to the shaft portion and to the shaft bearing hole change along the circumferential direction. The head cap is biased toward the closed position when located on the closed position side, and is biased toward the open position when located on the open position side.
