A visual recognition line for showing the division position of transfer marks is disposed between the transfer marks, and the leading edge of the transfer head is a visual recognition positioning part, and the coincidence of the two is recognized as the standard for transfer, so that the transfer mark of the mark transfer tape can be accurately transferred on a transfer area.

Abstract: In a coating film transfer tool, a tape is unwound from a supply reel, fed over a transfer head, and wound onto a take-up reel driven from the supply reel by a drive mechanism having slippage. Instead of setting the average slipping torque at a high value, or minimizing its variations, to prevent it from falling below the winding threshold, the initial slipping ratio is set at a value of at least 34%. This avoids slackening of the tape without the need for close manufacturing tolerances or lubricants, and without causing a condition in which excessive force is required to wind the tape onto a take-up reel in the later stages of the tool's useful life.
