PROBLEM TO BE SOLVED: To offset static electricity attaching to a paper sheet by a positive and a negative, and to prevent deceleration or stopping by static electricity attraction force between the paper sheet and a fixed guide by using a member lower in electrification than the paper sheet as a supply belt, and using a member higher in the electricifaction than the paper sheet as the fixed guide. SOLUTION: When the electrification of a supply belt 201 and a feed belt 207 is lower than a letter 214, when rubbing these belts, the supply belt 201 and the feed belt 207 are electrified to (-), and the letter 214 is electrified to (+). At this time, when the electrification of a fixed guide 213 is higher than the letter 214, the fixed guide 213 is electrified to (+) and the letter 214 is electrified to (-) by friction when the letter 214 slides on the fixed guide 213, so that static electricity of (+ and -) electrified to the letter 214 is offset and reduced, and attraction force is reduced so that the carrying letter 214 does not decelerate or stop on a guide surface. Therefor, a construction material of the feed belt 207 is formed of rubber, a construction material of the leter 214 is formed of paper, and a construction material of the fixed guide 213 is formed of plastic.
