Summary:PURPOSE:To enhance accuracy in judement by integrating thickness over the carrier length of a medium so as to be compared with the thickness integral capacity for one piece of the medium, and thereby judging whether or not double transmission takes place. CONSTITUTION:The presence or the absence of a medium 6 to be carried is detected by a medium detecting means 7, and the thickness of the medium 6 is then detected by a thickness detecting means 8. An integration means 10 integrates thickness over the carrier length (a space for an existence of a detected signal (a)) of the medium 6 based on the detected signal (a) by the medium detection means 7 and the detected signal (c) by the thickness detection means 8. An operation means 11 takes in an integral capacity (f) and an thickness integral capacity R for one piece of a normal medium recorded on a reference value storing means 9, the ratio (g) of both the integral capacities is obtained so as to be inputted to a double transmission judging means 12, so that it is judged whether or not double transmission takes place.
