An appropriate number of light-shielding sheets are arranged so as to be movable back and forth along the platen, and an original is attached to the end of each of the light-shielding sheets facing the platen, and whether a document exists in the platen portion corresponding to the end position of the light-shielding sheet. a document sensor that detects whether or not the light shielding sheet is present; a drive means that moves the light shielding sheet forward or backward as appropriate; and a drive that controls the drive means so that the light shielding sheet stops at the edge position of the document based on the output of the document sensor. a copying machine comprising: an encoder that outputs a pulse signal according to the amount of movement from a reference position of a light-shielding sheet that advances and retreats along the length direction of a platen; and a long copying sheet having predetermined dimensions. a roll of paper wound around a rotary shaft, a document size determining means for determining the length of the document by counting the output pulses of the encoder, and a roll fed out by the rotation of the rotary shaft. A copying apparatus comprising: a document size determining means; and a separating means, which separates the roll paper fed out by the rotation of the rotary shaft in conjunction with the output of the document size dividing means. Paper feeding device of the machine.
