PURPOSE:To efficiently and satisfactorily reuse a sheet by providing a mechanism which can contain plural erased sheets, and also executing the secondary erasion of the sheet without enlarging a device. CONSTITUTION:A sheet 1 taken out from the inside of a cassette 2 held in a cassette holding part 10 is fed in the direction A1 by a sheet carrying means 50, and when the tip of the sheet 1 carried in the direction A2 is held by a roller 52, a mobile carrying part 51 moves, and the sheet 1 is carried in the direction A3 by a switch-back, and carried into the first stacker 40. The sheet 1 is carried in the direction A5 by the sheet carrying means 50 and carried into a reading part 20. The sheet whose reading is ended is carried in the directions A8-A10 and carried toward a primary erasing part 30. The sheet 1 whose erasion is ended is carried in the directions A12-A14 and carried into the second stacker 100. The sheet 1 which is selected and taken out by one sheet each from the second stacker 100 is received, passes through a secondary erasing part 60, and thereafter, carried into the cassette 2 in the cassette holding part 10.
