According to the present invention, there is used a conveyance roller for the conveyance of a pasteboard with labels; a separating member is disposed on a downstream side from a pasteboard conveyance path with respect to a printing head which holds the pasteboard with labels between the same and a platen, and in a position close to the printing head; and a pinch roller is provided for holding between the same and the conveyance roller the pasteboard portion which has been bent and separated from a label after printing by the separating member. The conveyance of the pasteboard with labels for printing and the conveyance of the pasteboard for label separating can be done at a time by driving either the conveyance roller or the pinch roller.
