ABSTRACT:
A thermal printer has a paper feeder including a platen roller, and a casing including a separating roller, the paper feeder being attached to the casing to be openable and closable. In this printer, when the paper feeder is opened, the separating roller is driven in response to the opening operation, to be set to a retracted position that is clear of the platen roller. When the paper feeder is closed, the separating roller is driven in response to the closing operation, to be set to an operative position out of contact with the platen roller with a predetermined spacing therebetween extending axially of the platen roller.
