Claim:
A printer comprising: a printing device which prints information on a first sheet conveyed along a main conveying path, and a second sheet conveyed subsequently to the first sheet; a conveying device arranged on the conveying-out side of the main conveying path, and having a pair of conveying rollers which can be freely contacted with each other and separated from each other, which sandwich a front end side of the first sheet sent out from the main conveying path to convey the first sheet in a first direction, and which convey, after a trailing end side thereof passes the main conveying path, the first sheet into a second direction reverse to the first direction in the state that the trailing end side is directed ahead, so as to cause the first sheet to await at an awaiting position; a controlling device which controls in such a manner that the pair of conveying rollers are separated from each other to permit a front end side of the second sheet sent out from the main conveying path to be introduced into a gap between the conveying rollers, and based on a configuration that the distance from a trailing end side of the second sheet in a conveying direction to the pair of conveying rollers becomes equal to the distance from the trailing end side of the first sheet caused to await at the awaiting position to the pair of conveying rollers, the first and second sheets are sandwiched by the pair of conveying rollers so as to be conveyed in the first direction and be put onto each other, and subsequently the first and second sheets are conveyed to be sent out in the second direction; and a discharging unit which discharges the first and second sheets sent out in the state that the sheets are put onto each other.
