Abstract:
1. An application film transfer tool comprising, a) a supply bobbin around which an unused transfer tape is wound, the supply bobbin having a circular periphery and a first axis of rotation; b) a transfer head around which the transfer tape is extended, the transfer head pressure-sensitively transferring an application film of the transfer tape onto a transfer subject by pressing against the transfer subject; c) a take-up bobbin taking up the used transfer tape, the take-up bobbin having a second axis of rotation parallel to the first axis of rotation; d) a clutch mechanism engaged with the supply bobbin and the take-up bobbin for transmitting rotation of the supply bobbin to the take-up bobbin and controlling rotational speed of the take-up bobbin; and e) a reverse rotation prevention mechanism for preventing reverse rotation of the supply bobbin, said reverse rotation mechanism having engageable latching components including latching grooves and a latching protrusion engageable in the latching grooves such that engagement of the latching components permits rotation of the supply bobbin in one direction and prevents rotation of the supply bobbin in a direction opposite the one direction, one of the engageable latching components being provided on the supply bobbin for rotation with the supply bobbin and the other latching component being non-rotatable, the latching components being confined within the circular periphery of the supply bobbin and being engageable in a direction parallel to the first the axis of rotation of said supply bobbin, wherein part of the supply bobbin constitutes part of the reverse rotation prevention mechanism.
