PURPOSE: To provide a paper thickness detecting device capable of easily detecting the thickness of a paper sheet without providing an exclusive sensor etc. and a printer, in a paper thickness detecting device used for a printer capable of printing on the paper sheet having a different thickness and the printer. CONSTITUTION: The paper sheet 54 is abutted on the clearance between resister rollers 55 and 56 for feeding the paper, the rollers 55 and 56 are rotated to carry the paper 54 and its passage is detected by a paper passage sensor 57. Then, the time from the drive of the resister rollers 55 and 56 to the detection of the passage of the paper 54 by the sensor 57 is detected to detect the thickness of the paper 54 in accordance with the detected time. |
