PROBLEM TO BE SOLVED: To smoothly carry a cleaning card small in friction coefficient without increasing the capability of a motor. SOLUTION: When a cleaning card CL is carried, the central part of its rear edge first reaches a pair of 2nd carrying rollers 12. When the card CL are then inserted between vertical rollers 14 and 15 and is carried, the rear edge of a recessed part 5 of the card CL reaches the contact part 24a of a magnetic head 24. Since the card CL is completely held with the rollers 14 and 15 between at this point of time, the rear edge of the recessed part 5 goes over the contact part 24a by the carrying force of the rollers 14 and 15. |
