Abstract
Provided is a thermal transfer-system recording device which, by accurately conveying a medium between each of the thermal heads, eliminates image position displacement and image pitch variations between each of the thermal heads, thereby improving the overlay precision of each color and enabling printing on both sides of the medium. A pair of small pieces (300, 302) is provided between adjacent thermal heads and close to the conveying platen drum, and rollers (307, 308) are provided at both ends of the small pieces in the circumferential direction thereof. The rollers suppress separation of the recording paper from the platen drum by pressing the recording paper 100 against a flexible body 18A of the platen drum surface.
