The image erasing apparatus includes an erasing unit that erases an image, a reading unit that reads a size of the recording medium, a classification device that classifies the erasing-processed recording medium, and a control unit. The control unit recognizes the size of the erasing-processed recording medium based on data about the size, and controls the classification device to classify each recording medium from which the image has been erased for each different size. ## Claims ### Claim 1 An image erasing apparatus that erases an image formed on a recording medium, comprising: an erasing unit configured to erase the image formed on the recording medium; a reading unit configured to read a size of the recording medium; a classification device configured to classify each recording medium on which an erasing process of the image has been performed by the erasing unit, for each different size; and a control unit configured to recognize the size of the image erasing-processed recording medium based on data about the size read by the reading unit before a classification process performed by the classification device, and to control the classification device. ### Claim 2 (depends on 1) The image erasing apparatus according to claim 1, wherein the classification device includes first and second stock units that temporarily accommodate the recording medium which has not been classified yet, and a sheet discharge unit that accommodates the classified recording medium. ### Claim 3 (depends on 2) The image erasing apparatus according to claim 2, wherein the control unit repeats that each recording medium which has not been classified yet is alternately accommodated in the first and second stock units, and controls the classification device such that the recording medium with a predetermined size is accommodated for each repetition operation. ### Claim 4 (depends on 3) The image erasing apparatus according to claim 3, wherein the control unit controls the classification device such that all the recording media which have not been classified yet are accommodated in the first stock unit, then the recording medium with a predetermined first size among the recording media accommodated in the first stock unit is accommodated in the sheet discharge unit, and the recording media with sizes other than the predetermined size are accommodated in the second stock unit. ### Claim 5 (depends on 4) The image erasing apparatus according to claim 4, wherein the control unit controls the classification device such that the recording medium with a predetermined second size different from the first size among the recording media accommodated in the second stock unit is accommodated in the sheet discharge unit, and the recording media with sizes other than the second size is accommodated in the first stock unit. ### Claim 6 (depends on 5) The image erasing apparatus according to claim 5, wherein the sheet discharge unit has a sheet discharge box for accommodating the recording medium, and the sheet discharge box accommodates the recording medium with the first size, and subsequently accommodates the recording medium with the second size. ### Claim 7 (depends on 6) The image erasing apparatus according to claim 6, wherein the first size is larger than the second size. ### Claim 8 (depends on 5) The image erasing apparatus according to claim 5, wherein the sheet discharge unit has first and second sheet discharge boxes for accommodating the recording medium, the first sheet discharge box accommodates the recording medium with the first size, and the second sheet discharge box accommodates the recording media with sizes other than the first size. ### Claim 9 (depends on 8) The image erasing apparatus according to claim 8, wherein the first size is a size with a high frequency of use. ### Claim 10 (depends on 5) The image erasing apparatus according to claim 5, further comprising a reject box that accommodates the recording medium unrecognizable by the control unit.
