Patent ID: 8013885

Claim:
A printer comprising: a recording portion having a recording thermal head for performing recording on one side of a recording medium and having a recording platen roller disposed in pressure contact with the recording thermal head for conveying the recording medium; a thermal activation portion arranged at a position off a conveying course of the recording medium conveyed by the recording platen roller of the recording portion, the thermal activation portion having a thermal activation head configured to heat the other side of the recording medium and having a thermal activation platen roller disposed in pressure contact with the thermal activation head for conveying the recording medium; a first discharge port provided on a downstream side of the conveying course of the recording medium conveyed by the recording platen roller of the recording portion; a second discharge port provided on the downstream side of the conveying course of the recording medium conveyed by the thermal activation platen roller of the thermal activation portion; a pair of conveying rollers arranged between the recording portion and the first discharge port and between the first discharge port and the thermal activation portion, the pair of conveying rollers being configured for conveying the recording medium from the recording portion to the first discharge port through normal rotation of the pair of conveying rollers, for changing the conveying course of the recording medium conveyed from the recording portion, and for conveying the recording medium to the thermal activation portion through reverse rotation of the pair of conveying rollers; a control device for controlling the pair of conveying rollers such that (1) when the recording medium has on the one side thereof a recording surface on which recording is performed by the recording thermal head and has on the other side thereof a heat-sensitive adhesive layer that is heated by the thermal activation head, the pair of conveying rollers are caused to undergo normal rotation until a trailing end portion of the recording medium reaches the pair of conveying rollers, at which point the pair of conveying rollers are caused to undergo reverse rotation in a state in which the trailing end portion of the recording medium is nipped, and (2) when the recording medium has on the one side thereof a recording surface on which recording is performed by the recording thermal head and has the other side thereof which is not required to be heated by the thermal activation head, the pair of conveying rollers are caused to undergo normal rotation until the recording medium is discharged through the first discharge port; and a temporary stocking portion arranged on a downstream side of the pair of conveying rollers for temporarily retaining the recording medium on the one side on which recording has been performed by the recording thermal head.
