<p>PURPOSE: To improve the operability of a cleaning card and to efficiently use a dirt removal part evenly by integrally providing a stopper engaged with the peripheral edge part of a card insertion port on both side edges of the card. CONSTITUTION: It is required that an insertion length 1 of a cleaning card 1 into a card reader 20 is lengthened relatively, and the dirt removal part of which length from a tip to stoppers 3 is formed to be L1 , between a pair of dirt removal parts of a cleaning card 1 is inserted from the card port 27 until the stoppers 3 are engaged with the peripheral edge part of the card port 27 along the arrow. The insertion of the dirt removal part is detected by a detector (not shown in the figure), and a motor 37 is driven, and both transfer belts 33, 34 travel. At this time, the dirt removal part is placed on both transfer belts 33, 34, and since both transfer belts 33, 34 travel while pressing and holding the dirt removal part of the cleaning card 1 engaging the stoppers 3 with the peripheral edge part of the card port 27, the dirt on the both transfer belts 33, 34 is transferred to the dirt removal part and removed.</p> |
