COATING FILM TRANSFER DEVICE

PURPOSE:To reduce the number of part items by making slip the rotation of a winding core and the rotation of a delivery core by the elastic deformation, into a non-transmission condition, of a part to be engaged of a winding core which is engaged with the engaged part of a winding pivot shaft when an excessive tension is generated on a transfer ribbon with the rotation of the winding core. CONSTITUTION:A pivot shaft for delivery 9 to close-fit a delivery core 2 lockingly is provided in a transfer device case C, and a pivot shaft for winding 10 interlocked under the condition that a ribbon winding speed becomes faster than a ribbon delivery speed are provided on both pivot shafts 9 and 10. Also a part to be engaged 4b which is formed on an engaging part 10a is engaged with the engaging part 10a of the winding pivot shaft 10, and the part to be engaged 4b is formed so that it is deformed elastically in a non-transmitting condition when a relative rotational force of over a specified limit acts on it. By this, a slip interlocking mechanism to interlock the rotation of both cores 2 and 4 slipperily is formed. In addition, the part to be engaged 4b is made weaker in mechanical strength than the engaging part 10a.
