ABSTRACT:
In a recording apparatus of the type in which an image of an original is recorded on a recording sheet with the use of an elongated, web-like microcapsule sheet, it is contemplated to tightly wind the exhausted microcapsule sheet around a take-up roller without adversely affecting the formation of a latent image on a microcapsule sheet and/or development of the latent image. To this effect, when the recording operation is not being performed, a particular portion of the exhausted microcapsule sheet is grasped by a grasping unit and the take-up roller winds the exhausted microcapsule sheet while imparting a high tension thereto, whereby a space for accommodating the take-up roller can be made small. During the recording operation, the exhausted microcapsule sheet is free from the grasping force and the sheet is wound around the take-up roller while imparting a low tension thereto.
