摘要： A printing apparatus includes a printing head for printing on a bank book, a platen disposed opposite the printing head, and a cam mechanism for moving the platen. A sensor detects the thickness of the bank book which is between the printing head and the platen, and a sensor moving mechanism moves the sensor toward or away from the platen. A controller controls the operation of the cam mechanism and the sensor moving mechanism as the sensor is moved to a measuring position approaching the printing head. The platen is moved toward the printing head according to a detected value, and then the sensor is retracted from the measuring position. As a result, after moving the platen, the sensor does not contact the surface of the bank book, and therefore does not produce jamming or oblique feeding of the bank book during a line feed or printing operation.
