Abstract: PROBLEM TO BE SOLVED: To provide a recorder capable of being smoothly recovered from an unusual state, by a method wherein, though accidents such as a trouble, a power source disconnection etc. are generated, pressure weld between a platen or the like and a recording head is easily released. SOLUTION: A table printer, when a driving shaft of a stepping motor SN is rotated in one direction, executes pressure weld motion wherein a platen P1 is urged to come into contact with a recording head via a pivot transmission means SD. When the driving shaft is rotated in a reverse direction, the tape printer carries out separating motion wherein the platen P1 is separated from the recording head. The pivot transmission means SD is equipped with a double- layered gear NG wherein when separating motion is carried out by rotating the driving shaft in the reverse direction after executing pressure weld motion by rotating the driving shaft in one direction, its transmission is delayed for a specific time without transmitting rotation immediately in the reverse direction of the driving shaft.
