PROBLEM TO BE SOLVED: To execute cleaning processing only when a prescribed cleaning card is inserted by detecting light with part of a light receiving element group via the light transmitting part provided in the inserted card and judging it as a cleaning card. SOLUTION: A hole provided in a card is detected by a controller while the card is transported in the direction of the arrow F, the inserted card is judged to be a cleaning card 5, and thereby executes a cleaning processing. Driving of a motor is not immediately stopped after detecting, and the driving is continued for a specified time. Since a contact point block 21 can move only to the end of an oblique guide groove 13, the cleaning card 5 becomes forcidly locked by a card abutting member 23 on the way. Consequently, a slip is generated between the cleaning card 5 and a conveying belt 17, and then dirt stuck to the conveying belt 17 is wiped away. |
