Patent ID: 8573277

Claim:
A coating film transfer tool comprising: a feed spool around which an unused transfer tape is wound; a transfer head from which the transfer tape is suspended and which pressure transfers a coating film on the transfer tape suspended therefrom to a transfer-receiving object by pressing the coating film thereagainst; a take-up spool around which the transfer tape is wound after the coating film is transferred; a rotation transmitting means for transmitting a rotation of the feed spool to the take-up spool; a transfer portion case configured to hold the feed spool, the take-up spool and the rotation transmitting means; a slip member which pivotally supports the feed spool and which is loosely fitted in the transfer portion case; a feed-side gear securely fitted on the slip member in a position lying between the feed spool and the slip member; and a take-up-side gear which rotates together with the take-up spool, wherein the slip member has a shaft portion to which the feed spool is pivotally attached, an arm portion including an arm base portion formed in proximity to one end of the shaft portion and a plurality of arms that project outwards from the arm base portion, and a large diameter portion that is positioned at a boundary portion between the shaft portion and the arm base portion and has a shaft diameter that is larger than a diameter of the shaft portion, wherein the feed-side gear is a disc-shaped gearwheel in which teeth are formed along an outer circumferential edge and an opening is formed in a central portion as a fitting portion and has a plurality of abutment projections formed on an inner circumferential edge of the fitting portion for abutment with the large diameter portion of the slip member and an elastic opening that is provided as a circumferentially extending cutout in proximity to the position where the abutment projections are formed, wherein the transfer portion case includes a circular abutment wall that is centered around the shaft portion to which the feed spool is pivotally attached and with which arms of the slip member are brought into abutment, wherein a rotation of the feed spool is transmitted to the take-up spool by the gears, and wherein the transfer portion case and the slip member configures a load adjusting means that generates a slip torque between the arms and the abutment wall, and the slip member and the feed-side gear configures a rotational speed adjusting means for causing the feed spool to slip by virtue of the abutment projections which abut with the large diameter portion of the slip member so that the whole rotation of the feed spool is not transmitted to the take-up spool.
